Photosensor testing sorting machine

Abstract

The invention discloses a photosensor testing sorting machine which comprises a main tower rotating disc system, a feeding screening module and a feeding transfer device. The main tower rotating discsystem performs systematic control over module devices, a loading disc containing a device is placed on a product launching loading platform of the feeding screening module, a vision CCD device of thefeeding screening module recognizes the device, a device taking and placing suction nozzle selects a product of a correct directional surface from the loading disc, and the product is transferred toa device positioning reverse mold of the feeding transfer device; the feeding transfer device transfers the product to the portion under the working position of a vacuum suction nozzle of the main tower rotating disc system; the existing production mode that workers perform manual testing under the special environment and workers perform appearance inspection under a microscope is changed into themode that machine equipment intelligently and automatically selects a qualified product, and unqualified products are classified concentratedly; in this way, the production efficiency is high, the error rate is low, the mode can be popularized to mass production, the labor cost is greatly reduced, and the working efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of industrial automation, and in particular relates to a photosensitive device testing and sorting machine. Background technique [0002] A photoelectric conversion sensor based on the semiconductor photoelectric effect, also known as a photoelectric sensor. The use of light and electricity technology can achieve non-contact, long-distance, fast and accurate measurement, so semiconductor photosensitive devices are often used to indirectly measure other physical or chemical quantities that can be converted into light quantities. Semiconductor photosensitive devices are divided into photoconductive type and photovoltaic type according to the photoelectric effect (see photoelectric sensor). The main parameters and characteristics of semiconductor photosensitive elements are sensitivity, detection rate, illumination rate, illumination characteristics, volt-ampere characteristics, spectral characteristics, time ...

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to overcome the existing defects and provide a photosensitive device testing and sorting machine to solve the traditional method proposed in the above-mentioned background technology, which is manual testing in a special environment, and manual testing under a microscope. Product appearance inspection, select qualified products

This method has low production efficiency and high error rate, and cannot be extended to mass production; its production method cannot meet the high-speed, high-precision, high-reliability photosensitive device packaging product manufacturing process requirements.
