Description
The present invention relates to a kind of device of cutting masking tape, it can be used for the boundary belt of cutting is sticked on the metal tape, thus the non-coated portion on the protection metal tape.
Bar shaped applies band and can be used on the lead-in wire of various electric wire connecting junctions and integrated circuit lead frame.
It is a kind of bar shaped basal plane that bar shaped applies band, and it is by longitudinally applying as copper alloy, stainless steel, nickel or other isometric bonding jumpers, and coated portion and non-coated portion are banded continuously arranged mode and make.
Bar shaped applies the making of being with can be rapid in two steps, comprises that the boundary belt that will downcut is attached to the stickup step of making non-coated portion on the metal tape, reaches the step with gold, silver or fine material metallizing band.Coated copper or the internally coated preparation process of nickel before this process also can be included in and paste.
Along with the raising of integrated circuit, strict more as coating width and required precision at interval that the bar shaped coating of lead frame is with to the large scale integrated circuit degree of integration.The coating positional precision that requires is usually at+0.05mm or littler.
The precision that applies position and width directly depends on the stickup precision of used boundary belt.
In the step of traditional stickup boundary belt, require to adopt the cutter sweep that the boundary belt high accuracy can be cut into given width, to improve the stickup precision of boundary belt.
In the flat 3-178796 of the uncensored patent publications No. of Japan (referring to Fig. 4), a kind of traditional boundary belt cutter sweep is disclosed.Boundary belt MT is longitudinally cut into the rectangular of several various width on reception wheel 104.Cut by cutting blade 105.
Boundary belt MT is in extended state during cutting on reception wheel 104.In this case, if cutting blade 105 is not pressurized on the boundary belt MT, just be not easy cutting masking tape.Therefore, this has just increased the cutting resistance that is added on the cutting blade 105, makes the adhesive force of boundary belt MT be easy to attached on the cutting blade 105.So just be provided with X-axis objective table 112, be used for mobile continuously cutting blade 105, to avoid causing cutting power to descend on the cutting blade 105 owing to boundary belt MT sticks to.
If receiving on the wheel 104, the biasing force of cutting blade 105 cutting masking tape MT is excessive, and cutting blade will be interfered mutually with reception wheel 104.On the contrary, if the biasing force of cutting blade 105 too a little less than, cutting blade 105 can not cutting masking tape MT.Y-axis objective table 111 is set is the interference that is used for preventing to receive between wheel 104 and the cutting blade 105, and accurately adjust the biasing force that is applied on the boundary belt MT.
The quantity of cutting blade 105 is identical with slitting quantity, and the interval that equates with the slitting width is arranged.Z axle objective table 110 is set, and is to be used for moving at the width of boundary belt MT the device of cutting blade 105, makes its position with metal tape J consistent.
If metal tape J is every through 10m, the long blade of 1cm is when arrow W direction moves 1mm, and the maximum length of the metal tape that can cut with such cutting blade is 100m.Like this, because the sword face length degree of cutting blade determines that if the total length of metal tape is longer than the maximum length of the metal tape that can cut, the amount of movement of X-axis objective table 112 is just little than predetermined value.Therefore, metal tape is long more, and the mobility of X-axis objective table 112 is more little, causes edges dull.In some cases, because moving boundary has just been stated in the amount of movement error before stickup is finished, like this, will continue to finish stickup by blunt cutting blade 105.
The biasing force adjustment of Y-axis objective table 111 is very strict, so that needs consummate experience to carry out highly difficult like this operation.Excessive biasing force will cause cutting blade 105 and reception wheel 104 mutual generations to be interfered, thereby can damage cutting blade 105.On the contrary, too weak biasing force can make the cutting blade 105 can not cutting masking tape MT.
Purpose of the present invention just provides a kind of device of cutting masking tape, and it has overcome the above-mentioned defective of prior art, has little cutting resistance, and can easily adjust the position of cutter.
