[0017] To facilitate those skilled in the art to understand the present invention, specific embodiments of the present invention are described below with reference to the accompanying drawings.

[0018] like Figures 1 to 4As shown, the present invention provides an automatic packaging detection device for light-emitting diodes, comprising a guide groove 1 with an opening on the lower side, a belt conveyor assembly 2 is arranged on the lower side of the guide groove 1, two pulleys of the belt conveyor assembly 2 are connected to an axial offset driving device, and the axial offset driving device can drive the belt conveyor assembly 2 to move back and forth along the direction of the pulley shaft, and multiple groups of detection modules are arranged in the guide groove 1 along the length direction, the detection module includes a detector 3 and a light-shielding member 9, the detector includes a first electric telescopic rod 31, the upper end of the first electric telescopic rod 31 is connected to the steering gear 32 at the top of the guide groove, the telescopic rod end of the first electric telescopic rod is fixedly installed with a hook 33, the telescopic rod end of the first electric telescopic rod is located at the front side of the hook 33 and two flexible electrode sheets 34 are installed through a bracket, the flexible electrode sheets are preferably made of relatively thin copper sheets, the two flexible electrode sheets are connected to the electrical detection device, when the two pins of the light-emitting diode 11 are respectively in contact with the flexible electrode sheets, the electrical detection device supplies power to the diode, and changes the power supply The positive and negative properties of the electrical electrodes can detect whether the light-emitting diode is energized. A light sensor 35 is installed on the bracket. The light sensor 35 and the electrical detection device are both connected to the computer. If the light sensor senses a light signal during the detection process and the computer receives the power-on information sent by the electrical detection device, it means that the light-emitting diode is qualified. At this time, the first electric telescopic rod is shortened and the light-emitting diode passes. If the electrical detection device does not detect a current signal, the servo drives the first electric telescopic rod to rotate toward the diode while the first electric telescopic rod extends, raising the front end of the light-emitting diode through the hook, so that the light-emitting diode can be turned around, and then the diode continues to move forward to the next detection module for detection. A toggle component is provided on the rear end of the guide groove. The toggle component will toggle the light-emitting diode that is still unqualified after being detected by multiple detection modules to one side to leave the belt conveyor assembly. The light-emitting diode that has successfully passed multiple groups of detection modules enters the packaging module at the rear end of the belt conveyor assembly.

[0019] The shading member 9 is preferably made of flexible fabric, and the upper end of the shading member is fixedly connected to the top of the guide groove. The shading member 9 separates the detectors of multiple detection modules and can separate different light sensors to avoid different groups from affecting each other during detection.

[0020] The toggle assembly includes a motor 4 fixedly installed at the top of the guide groove, a paddle 5 is installed on the output shaft of the motor 4 through a connecting component, and a proximity sensor 6 is set at the top of the guide groove in front of the motor. When a light-emitting diode determined to be unqualified passes by the proximity sensor, it is sensed, and then when the light-emitting diode moves to the paddle position, the motor drives the paddle to rotate and move the diode to one side to slide it into the waste collection box outside the belt conveyor assembly. A notch 7 is set in the guide groove corresponding to the paddle position.

[0021] An inclined feed trough is set at the front end of the guide groove. The feed trough is expanded. The end of the feed trough and the width of the guide groove are slightly larger than the diameter of the light-emitting diode. This design can ensure that the entering light-emitting diode cannot move sideways or automatically turn while continuing to move forward.

[0022] The axial offset drive device includes a guide rail 8, and the shaft seats of the two pulleys of the belt conveyor assembly 2 are installed on the guide rail through a slider 9, and the slider is connected to the second electric telescopic rod 10. The extension and contraction of the second electric telescopic rod can drive the belt conveyor assembly to move horizontally, thereby driving the light-emitting diode in the guide groove to rotate. The belt conveyor assembly drives the light-emitting diode forward while driving it to rotate. When the light-emitting diode moves to the position of the flexible electrode sheet, it can ensure that the light-emitting diode pins can be adjusted to a horizontal distribution by rotation when they are distributed up and down, and can ensure connection with the two flexible electrode sheets to ensure the accuracy of detection. The above-described embodiments of the present invention do not constitute a limitation on the scope of protection of the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the claims of the present invention.
