Automation test wire of photoelectric detector

Abstract

The present invention discloses an automation test wire of a photoelectric detector. The test wire comprises a detection tool and an automatic push track, the detection tool comprises a rack, an upper tool plate and a lower tool plate, the lower tool plate is fixed on the rack, the two sides of the upper tool plate are respectively provided with one set of driving mechanism, each driving mechanism comprises a cylinder, a guiding track, a lower movable block, an upper movable block, a pressure spring and a connection rod, and the automatic push track comprises a first track cylinder, a second track cylinder, a pneumatic track sucker, a track conveyer belt and a track structure. Operators can directly put the photoelectric detector into a grip slipper from the right side to avoid hidden troubles caused by an original design, improve the safety operation coefficients, improve the operation field of vision and allow the operation to be more convenient and rapid. The automation test wire of the photoelectric detector can automatically push the photoelectric detector into the tool, is high in automation degree, can realize reciprocating motion of the photoelectric detector and can greatly improve detection efficiency.

Description

technical field [0001] The invention relates to an automatic test line for a photoelectric detector. Background technique [0002] The principle of a photodetector is that radiation causes a change in the conductivity of the irradiated material. Photodetectors are widely used in various fields of military and national economy. In the visible or near-infrared band, it is mainly used for ray measurement and detection, industrial automatic control, photometry, etc.; in the infrared band, it is mainly used for missile guidance, infrared thermal imaging, infrared remote sensing, etc. Another application of the photoconductor is to use it as the target surface of the camera tube. In order to avoid image blur caused by the diffusion of photogenerated carriers, high-resistance polycrystalline materials, such as PbS-PbO, Sb2S3, etc., are used on the continuous film target surface. Other materials can adopt the method of inlaying the target surface, and the entire target surface is...

Problems solved by technology

In the existing photodetector manufacturing process, batch quality inspection of photodetectors is an important part of the production process. The existing photodetector quality inspection equipment passes the upper jig plate 2 and the lower jig plate 3 Fix the photodetector in the jig, apply light to the photodetector, and process the output signal of the photodetector to determine whether the photodetector meets the factory standard. , the lower fixture plate 3 is fixed on the frame 1, and the upper fixture plate 2 is vertically slid and installed on the frame, so it is necessary to manually place the photodetector on the lower fixture plate and control the upper fixture The plate moves downward to realize the positioning of the photodetector, but in this operation mode, it is easy to cause the upper fixture plate to press down on the operator's arm due to operational errors or equipment failures, resulting in safety accidents; Less efficient operation on the lower fixture plate
