Description

A LED product testing device with a clamping station

technical field

The utility model belongs to the field of LED product testing equipment, in particular to an LED product testing device with a clamping station.

Background technique

At present, with the continuous improvement of technology, LED products (Light Emitting Diode, light emitting diode) are widely used in people's life.

Taking spherical LEDs as an example, since each LED has different luminous characteristics, it is necessary to test and classify the LEDs. For spherical LEDs, the illuminant is spherical, the pins are arranged at the bottom of the illuminant, and the electrodes are arranged in the illuminant. If the LED product is tested, it is necessary to use a probe to extend from the bottom of the luminous body of the LED product into the luminous body, so that the probe is in contact with the electrode. In the existing test methods for LED products, there are usually two ways of clamping LED products. One is to use a suction nozzle to suck the LED product, so that the probe extends from the bottom of the LED product luminous body into the luminous body. Carry out the test, when the test is completed, the LED product is sucked by the suction nozzle and continues to be conveyed. The other is to place the LED product on the conveying mechanism, and the probe is set under the LED product. The probe extends from the bottom of the LED product, from bottom to top, into the interior of the luminous body of the LED product. When the probe abuts against the electrode, the LED product will be subjected to a force from bottom to top, and this force will make the LED product move upward. Therefore, a pressure plate is usually arranged above the LED product. During the test, the pressure plate presses the LED product tightly to prevent the LED product from moving upward. When the test is completed, the probe first releases the electrode, and then the pressure plate releases the LED product. The LED product enters the next station under the transmission of the transmission mechanism.

However, in the above-mentioned test method for LED products, there are still such problems:

1. The LED product is sucked by the suction nozzle, and the LED product is stable by the suction force of the suction nozzle. During the transmission process of the LED product, or when the probe detects the LED product, the LED product is easy to fall due to external force, thus Damage to LED products will affect the testing efficiency of LED products.

2. When pressing the upper end of the luminous body of the LED product with a pressure plate, the pressure plate will block the light emitted from the upper end of the luminous body, which will affect the test effect; When leaving the LED product, the LED product will easily stick to the pressure plate, and leave the station with the pressure plate, or fall to other positions. In this way, it is not convenient for the LED product to be transferred to the next station, which greatly affects the production efficiency .
