Description

Technical Field

[0002] Photoelectric detectors are sensors that convert light radiation signals into electrical signals using materials with photoelectric effect. The greater the light intensity, the greater the photocurrent. When there is no light, it is almost an insulator. Currently, it has been widely used in various fields such as industrial automation, smart wearables, missile guidance, light measurement and detection, flame detection, and communications.

[0003] There are also some technical studies on the testing of photoelectric detectors. For example, the announcement number: CN221261180U discloses a testing device for photoelectric detectors, including a tester body, a probe, a base, a tray and an ultraviolet lamp. The probe is installed on the outside of the tester body, a motor is fixedly installed inside the base, the tray is fixedly connected to the output end of the motor, a placement groove is provided on the surface of the tray, a support frame is fixedly installed on the outside of the base, and a connecting block is slidably connected to the surface of the support frame. In this invention, by setting the connecting block, the staff can drive the tray to rotate through the motor to move the photoelectric detector chip to the bottom of the probe, and then control the electric telescopic rod to retract, drive the connecting block to move downward, so that the probe can contact the contacts of the photoelectric detector chip under the push of the spring for detection. The whole process is simple and quick to operate, and there is no need for the staff to manually connect the probe to the contact, which is convenient for the staff to use for testing.
