[0020] 所述的第一、第二光接收传感器列阵器件选用相同的器件,并使两个光接收传感器列阵安装时在垂直位置上有一个错位,错位的距离为光接收传感器列阵中相邻两个光敏管间隔的一半,这样就保证了光信号的全部接收。 [0020] said first and second light receiving devices use the same sensor array device, and the two light receiving sensor array is mounted on a displacement in the vertical position, the displacement distance of the light receiving sensor array the spacing between two adjacent photodiodes half, thus ensuring all the received optical signal. [0021] 本发明的工作原理说明如下: [0021] The working principle of the present invention will be described as follows:

[0022] 发光管组件1发出的光束经光发射集光镜2形成平行光束,光束穿过间歇旋转的被检测的透明或半透明密封溶器(安瓿及输液瓶等)3,进入光接收集光镜4,由成像镜5形成被检测容器中溶液区域的成像光束,成像光束直接到达第一光接收传感器列阵7。 [0022] The light beam emitted by the light-collecting mirror the arc tube assembly 2 forms a parallel beam emitted from the light beam passes through the intermittent rotation of the detected transparent or translucent sealing melting device (ampoules and infusion bottles) 3, into the light-receiving set Light mirror 4, the light beam detected by imaging solution container area, the imaging beam directly to the first light receiving sensor array is formed by the imaging lens 5 7. 这样成像光束是被单个光接收传感器列阵所接受,但光接收传感器是由几十个独立的光敏管组成,因而光敏面不是连续的。 Such a single imaging light beam is accepted by the light receiving sensor array, but the light receiving sensor is composed of dozens of independent photosensitive tubes, and thus the photosensitive surface is not continuous. 如图3所示,图中带剖面线为光敏面,其余为盲区。 As shown, in Figure 3 hatch with a photosensitive surface, the rest is blind. 这样投射到光接收传感器列阵的成像光束没有全部转换成电信号,只有投射到光敏面部分的光信号被转换成电信号。 Thus projected onto the light receiving sensor array are not all the imaging beam into an electric signal, only projected onto the photosensitive surface portion of the optical signal is converted into an electric signal. 而投射到盲区的光信号不能转换成电信号。 The blind spot projected onto the optical signal can not be converted into an electrical signal. 为了补充盲区区域光信号接收,本发明提出了如图1所示的光路结构和如图2所示具体结构的具有双光信号接收传感器列阵结构的自动异物检查机。 To supplement the blind spot area of the light receiving signal, the present invention provides an optical structure as shown and illustrated in the specific structure shown in Figure 2 has a dual structure of an optical signal receiving sensor array automatic foreign matter inspection machine. 本发明一个特点就是在到达第一光接收传感器列阵7的光路中增设了45度半反射半透射分光镜或分光立方棱镜6,这样接收的成像光束被45度半反射半透射分光镜分光立方棱镜6分成二束光,分别形成了相同的二个图像,其中一个图像由光接收传感器列阵7接收,另一个图像由光接收传感器列阵8接收。 A feature of the present invention is to reach the first light receiving sensor array 7 in the optical path of the addition of 45 semi-transmissive semi-reflective dichroic mirror or dichroic prism 6 cubic, thus received imaging light beam is 45 degree semi-reflective semi-transmission dichroic beamsplitter cube 6 the prism into two beams, are formed of the same two images, one image received by the light receiving sensor array 7, another image sensor array 8 is received by receiving light. 这样接受的光信号被分成了二部分,如图4所示,图4设定光图像信号等分分割。 Such received optical signal is divided into two parts, as shown in Fig 4 setting signal light image segmentation 4 aliquots. 分割后光接收区和暗区垂直方向上宽度相等.左斜线部分如图5所示,右斜线部分如图6所示。 After receiving an equal split on the light and dark areas of the vertical width of the left shaded area as shown in Figure 5, right hatched portion shown in Figure 6. 如果如图5所示部分的光信号被光接收传感器列阵7接收,那末图6所示部分的光信号就被光接收传感器列阵8接收。 As shown in FIG. 5, if the optical signal by the light receiving portion 7 receives sensor array, then the portion of the optical signal is shown in Figure 6 to 8 receives light receiving sensor array. 图4表示全部光信号,这样的双光接收传感器列阵结构,使光信号的接收就不会因光敏管之间的不灵敏区遗漏了。 Figure 4 shows all of the light signal, this double light receiving sensor array structure, the received optical signal will not cause a dead zone between the photodiode missing.

[0023] 如果光路结构中的选择相同的光接收传感器列阵器件,两个光接收传感器列阵安装时在垂直位置上设有一个错位,错位的距离为光接收传感器列阵中相邻两个光敏管中心距离的一半。 [0023] If the optical structure of the light receiving sensor select the same array device, two light receiving sensor array installation with a displacement in the vertical position, the displacement distance of the light receiving sensor array adjacent two half from the center of the photodiode. 这样就保证了光信号的全部接收。 This ensures that all of the received optical signal. 如果光敏管光敏区垂直方向上的宽度大于盲区宽度则光信号的接收有一定的覆盖度,但是光敏管光敏区垂直方向上的宽度不能小于盲区宽度,这样会造成光信号接收的遗漏。 If the width of the vertical photodiodes blind photosensitive area is greater than the width of the received optical signal has some coverage, but the width of the photosensitive area photodiode in the vertical direction can not be less than the width of the blind, this will cause the optical signal received omissions.

[0024] 本发明另一个特点则是在两个光接收传感器列阵前均设置有光栏,光栏为狭缝光栏,调节光栏的宽度可以调节进入光接收传感器列阵的光通量,同样也调节了检测异物的信噪比(被检有效面积和异物面积的比例),光栏狭缝越小,相对检测信噪比越高,可以充分提高光检测信噪比,调节光栏狭缝宽度即可调节检测信噪比,提高灵敏度。 [0024] Another feature of the present invention is in the two light-receiving sensor array are set before the light bar, light bar slit diaphragm, adjust the column width of the light can be adjusted into the light receiving sensor array flux, the same also adjust the signal to noise ratio to detect foreign matter (subject effective area and foreign area ratio), the smaller the slit diaphragm, the higher the signal to noise ratio relative to detect, can fully improve the light detection signal to noise ratio, adjust the slit diaphragm SNR detection width can be adjusted to improve sensitivity. 而其它的光信号全部无遗漏接收的领域,例如:光纤,光敏管错位安装,但光栏狭缝宽度不能任意调小,不能充分提高信噪比。 And all of the other light signals received no missing areas, such as: optical fiber, photodiodes dislocation installation, but the light bar can not arbitrarily transfer a small slit width is not sufficiently improve the SNR.
