- FIG. 1 illustrates the particle loading apparatus
- FIGS. 2a and 2b illustrate a cross-sectional view of The invention relates to apparatus useful in loading 5 the rotating member of FIG. 1.
- the invention comprises a pin dispenser which is not wholly dependent on the force of gravity for aligning and dispensing a plurality of pins.
- a plurality of feed tubes feed small and lightweight pins to a rotary dispenser having a sleeve with a plurality of apertures equivalent in number to the number of pins to be dispensed simultaneously.
- a rotor within the sleeve contains a number of cavities extending radially into the rotor and corresponding in number and position to the apertures in the sleeve, with each said radial cavity interconnected by a longitudinal cavity.
- a vacuum source and an air pressure source are alternately connected to said longitudinal cavity and controlled by the rotation of the rotor acting as a rotary valve, such that in the feed phase of the operation the air pressure differential created by the vacuum source assists in feeding the pins to the rotor.
- the rotor Upon completion of the feed phase, the rotorrotates within the sleeve until the rotor cavities are aligned with a second set of apertures within the sleeve. Simultaneously, the longitudinal cavity becomes aligned with the air pressure source.
- the air pressure differential created by the air pressure source expels the pins from the axial cavities in the rotor and through the apertures in the sleeve.
- Suitable dispensing means or output tubes may be attached to the sleeve to direct the pins to the unit within which the pins are to be accurately positioned.
- a primary object of the invention is to provide a simple means for distributing lightweight particles from a magazine into predetermined positions in a receiving member.
- Another object of the invention is to provide a means which is essentially independent of the force of gravity to feed small lighweight particles into a receiving memher.
- Another object of the invention is to provide a means having a high confidence level in simultaneously feeding a plurality of particles to a receiving member.
- Another object of the invention is to provide a particle dispensing machine which has a minimum of mov ing parts and bearing surfaces.
- Another object of the invention is to provide a particle dispensing means which uses readily available peripheral equipment to thereby reduce the cost of incorporating the invention into present manufacturing environments.
- DESCRIPTION OF THE PREFERRED EMBODIMENT Pin loading devices are generally used as part of the manufacturing process in making various types of electric and electronic devices.
- the portion of the devices made during this phase of the manufacturing process is the means by which the resulting'device communicates with the outside world, that is, the means by which power is introduced to it and control signals are entered, as well as the basic input and output connections.
- the means for communication is by way of electrically conducting pins extending from the device and mating with a suitable receptacle in the apparatus to which the device is attached.
- the pins are short thin lengths of wire piercing but sealably connected to a part of the envelope of the device.
- the location of th pins is within a defined area or portion of the envelope, usu ally the base of the'device.
- a common illustration of this type of device is the well known electronic tube. 1
- the minimum pin size is a variable function dependent primarily on the weight of the pin and the friction of the passageways through which it must travel. As the ratio of friction toweight increases, the reliability of each tube simultaneously depositing a pin within the envelope base decreases 'rapidly as a function of the number of pins to be deposited. Consequently, the rejection rate of incomplete or faulty pin assembly in the envelope base is substantially increased.
- magnets or electromechanical coils are used to orient or guide the pins into the feed tubes. The pins may become magnetized and will then tend to attach themselves to other magnetic materials, resulting in an impeded flow of pins and a decreased operational reliability. Either situation raises the over-all cost of manufacture, and for devices having low profit margins, the economic feasibility of the devices is in jeopardy.
- the pin assembly technique taught in the instant'invention overcomes the prior reliance on gravity and provides a measure of reliability relatively independent of the pin size and only incidentally associated with the sliding friction present in the pin channelling passageways.
- a hopper l or magazine which may be any one of several configurations, serves the purpose of orienting the pins along their longitudinal axis in a plurality of streams.
- a plurality of feed tubes 2, each associated with a stream of pins, are attached to the hopper 1 in a receiving relationship, whereby the pins are fed into the tubes 2.
- the feed tubes 2 are also connected to a circular sleeve 3.
- the sleeve 3, enveloping a cylindrical member 4, is perforated by a first set of apertures or holes 5, which may be aligned in a row along the longitudinal dimension of the sleeve.
- Each of the feed tubes 2 is associated with one of the holes in this first set of 25 holes.
- a second set of holes 6, which may also be aligned in a row in the direction of the longitudinal aixs of sleeve 3, are located in the same longitudinal positional relationship as the first set of holes 5.
- Each one of a plurality of output tubes 7 is associated with each of the holes 6 in the second set.
- the rotor or cylindricalmember 4 shown in perspective in FIG. 1 and on end in FIGS. 2a and 2b, may be described as follows.
- the cylindrical member 4 may have two.diametrically opposed longitudinally oriented cavities 8, 9.
- Each of the longitudinal cavities is associated with a plurality of radial cavities or passageways l connecting the longitudinal cavity with the surface of the cylindrical member 4.
- Each of these passageways is positionally oriented to and matches with a corresponding hole in each of the sets of holes in the sleeve 3.
- rotation of the cylindrical member 4 within the sleeve 3 will periodically cause the passageways 10 to be aligned with the holes in each of the sets of holes in the sleeve 3.
- a first rectangular like member 12 shown in FIG. 1 is representative of apparatus acting as a rotary valve, and as the means by which the cylindrical member 4 is connected to both air pressure and vacuum sources. It contains two channels 13 and 14, one end of each having an aperture 15, 16, respectively, facing the cylindrical member 4 and the other ends connected to air pressure and vacuum sources through tubes 17 and 18, respectively.
- the orientation of the apertures l5, 16 is such that as the cylindrical member 4 rotates, the longitudinal cavities 8, 9 therein will periodically align themselves with each of the apertures l5, 16.
- a second rectangular like member 19 is representative of the support and drive means for rotating the cylindrical member-t.
- a crank 20 is shown attached to the cylindrical member 4, it is to be understood that a geared shaft or any other means may be used to connect the cylindrical member 4 to the rotating drive means 20.
- the drive means also includes the requisite timing apparatus, whether it is mechanical or electronic, to control the cylindrical member 4 rotation.
- the drive means may be arranged to rotate the cylindrical member 4 in a step like fashion so as to permit it to halt momentarily, whenever the radial cavities in the cylindrical member 4 are aligned with the holes in the sleeve 3.
- the drive means may also be designed to sequentially rotate the cylindrical member 4 in each direction within the angle represented by the input and output tubes attached to the sleeve.
- Such an arrangement permits the utilization of rotational limiters to insure that the apertures within the sleeve 3 are aligned with the axial cavities of the cylindrical member 4 during the pin injection and ejection operations.
- the use of a rotating member decreases the number of bearing surfaces required'compared to prior art devices and thereby the wear characteristic is also improved.
- the output tubes 7 attached to the sleeve 3 correspond in number to the input tubes 2.
- the receiving member 21 shown is illustrative of any member to which the exit end of the output tubes 7 may be attached.
- the receiving member 21 contains holes 22 each matched and aligned with a respective output tube exit.
- the orientation of the output tube exit ends shown is that of the pin positions normally used for a standard electronic tube.
- the portion of the envelope (base 23) discussed above which is to receive the pins may be operably connected to and aligned with the receiving member holes 22.
- the hopper l aligns the pins 24 and feeds them into the respective input tubes 2.
- the pins 24 within the feed tubes 2 lie end to end and the foremost pin lies within at least a portion of the sleeve 3.
- the cylindrical member 4, then aligned as shown in FIG. 2a, will have the passageways 10, associated with the longitudinal cavity 8, aligned with the holes 5 in the sleeve 3 and the feed tubes 2.
- the foremost pins positioned within the feed tube 2 will then be free to enter the passageway 10.
- the longitudinal cavity 8 is aligned with the aperture 15 of channel 13 and associated with a vacuum source connected to tube 17. Thereby, there will be a partial vacuum within the cavity 8.
- the hole depth used must be such that the pin 24 entering the cylindrical member 4 comes to rest without any portion of it extending beyond the perimeter 11 of the cylindrical member 4. Similarly, the pin will extend approximately up to the perimeter 11 of the cylindrical member 4 in order to support and prevent the succeeding pin 24 from extending beyond the sleeve 3 into the passageway 10 of the cylindrical member 4. If these caveats are not observed, the pins 24 lodged between the sleeve 3 and the cylindrical member 4 may hinder the rotation of the cylindrical member 4 within the sleeve 3.
- the cylinder surface may be relieved about the passageway 10 to accommodate the normal range of tolerances in pin length.
- the invention may easily be expanded to include a plurality of sets of output tubes operating in conjunction with a plurality of axial passageways whereby the output tubes may be fed alternately, or seriatum, or in some other scheme.
- there may be a plurality of pairs of input and output tubes whereby several sets of pins may be fed to their respective envelope bases per revolution of the cylindrical member. Appropriate modifications will then have to be made tochannels 13 and 14.
- Pin aligning apparatus for positioning electrical contact pins in a pin support member of an electron tube, comprising a rotatable cylinder having a plurality of radially directed cavities arrayed lengthwise of the cylinder, each radial cavity extending inwardly from the periphery of the cylinder to a depth substantially equal to or less than the length of a pin, and a longitudinally directed cavity interconnecting the bottom region of the radial cavities adapted for alternately coupling to an air source and a vacuum source,
- a sleeve concentrically disposed about the cylinder in closely spaced relation therewith having first and second pluralities of apertures spaced peripherally on the sleeve and each plurality respectively arrayed lengthwise of the sleeve at distances corresponding to the distances between the cylinder radial cavities, each aperture being shaped to accommodate an individual pin oriented lengthwise for passage through the aperture,
- output means for receiving pins from the second plurality of apertures, said output means being so constructed and arranged as to direct individual pins to prescribed positions in the electron tube pin support member, and
