SMD LED is a new type of surface-mounted semiconductor light-emitting device, which has the advantages of small size, large scattering angle, good uniformity of light emission, and high reliability. It is widely used in electronic devices that require signal indication and lighting. in components. In the prior art, manufacturers will carry out sampling tests on the SMD LEDs. The general testing process is to solder several SMD LEDs to the circuit board in sequence, and then pass through the two ends of the SMD LEDs respectively. The wire is connected to the power supply, so as to judge whether the SMD LED is qualified by whether it emits light.

However, the above-mentioned testing process has great defects: (1) Since the diode is small in size and the pin points are located on the sides and bottom of the two poles, it takes a lot of energy and time to solder it on the circuit board ;(2) During the test, if the soldering time of the soldering iron exceeds 3 seconds, it will cause color cast, dim or no light of the diode, which will affect the accuracy and progress of the test; Diodes are generally scrapped, so they cannot be reused, resulting in a waste of resources.

In view of this, it is necessary to provide a light emitting diode detection device to solve the above defects.
