Problems solved by technology
[0003] At present, many optocouplers need to be inspected after production, but the existing inspections are all manually installed on the circuit after installation. The number of legs of the optocoupler is different, which will affect the detection effect due to misoperation, and cannot be compared. The second stage distinguishes the quality of light-emitting diodes and light-receiving triodes

The invention discloses a quality testing device for optocoupler production. The device comprises a detection bench. Grooves are formed in the two sides of the detection table. An electric push rod isarranged in the groove in one side. The output end of the electric push rod is connected with a mobile detection plate. A clamping frame is arranged on the inner wall of the groove in the other side,a fixed detection plate is connected to the inner wall of the clamping frame in a clamped mode, a first universal meter and a second universal meter are arranged on the two sides of the detection table respectively, a battery bin is arranged on the side, close to the second universal meter, of the detection table, and the fixed detection plate is connected with the first universal meter in series. According to the invention, the electric push rod replaces a manual electric coupler installation process, the violent installation process of fragile pins is reduced, the movable detection plate can be replaced to achieve detection of different pin electrical couplers, two circuits are arranged during detection, and the quality and magnification times can be accurately judged through the photoelectric effect. Compared with a traditional detection effect, the quality of the produced electrical couplers is more visually and comprehensively reflected, and the detection operation of assembly line production can be matched.
Description
technical field [0001] The invention relates to the technical field of optocoupler production, in particular to a quality testing device for optocoupler production. Background technique [0002] Optocoupler is also called opto-isolator or opto-coupler, referred to as opto-coupler. It is a device that transmits electrical signals with light as the medium. Usually, the emitter (infrared light-emitting diode LED) and the light receiver (photosensitive semiconductor tube) are packaged in the same package. When the input terminal is powered on, the light emitter emits light, and the light receiver generates photocurrent after receiving the light, which flows out from the output terminal, thus realizing the "electricity-optical-electricity" conversion. The optocoupler, which uses light as a medium to couple the input signal to the output, has the advantages of small size, long life, no contact, strong anti-interference ability, insulation between output and input, and one-way sig...
