[0020] To facilitate those skilled in the art to understand the present invention, specific implementations of the present invention are described below with reference to the accompanying drawings.

[0021] 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 at the lower side, a belt conveyor assembly 2 is arranged at the lower side of the guide groove 1, two pulleys of the belt conveyor assembly 2 are connected to an axial offset driving device, the axial offset driving device can drive the belt conveyor assembly 2 to reciprocate along the direction of the pulley shaft, a plurality of detection modules are arranged in the guide groove 1 along the length direction, the detection module comprises a detector 3 and a shading member 9, the detector comprises a first electric telescopic rod 31, the upper end of the first electric telescopic rod 31 is connected to a steering gear 32 at the top of the guide groove, a hook 33 is fixedly installed at the end of the telescopic rod of the first electric telescopic rod, the end of the telescopic rod 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 is extended. The front end of the light-emitting diode is raised by 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 set on the rear end side 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, and 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.

[0022] 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 influence between different groups during detection.

[0023] The paddle assembly includes a motor 4 fixedly mounted at the top of the guide groove, a paddle 5 is mounted on the output shaft of the motor 4 via a connecting component, a proximity sensor 6 is arranged at the top of the guide groove in front of the motor, when a light emitting diode determined to be unqualified passes through 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 moves the diode to one side to slide into the waste collection box outside the belt conveyor assembly, and a notch 7 is arranged in the guide groove corresponding to the paddle position.

[0024] An inclined feed groove is arranged at the front end of the guide groove, and the feed groove is flared. The end of the feed part and the width of the guide groove are slightly larger than the diameter of the reflective diode. This design can ensure that the entering reflective diode cannot move sideways or automatically turn while continuing to move forward.

[0025] The axial displacement driving device includes a guide rail 8, and the shaft seats of the two pulleys of the belt conveying 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 belt conveying assembly can be driven to translate through the extension and contraction of the second electric telescopic rod, thereby driving the light-emitting diode in the guide groove to rotate. The belt conveying assembly drives the light-emitting diode to move 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 pins of the light-emitting diode can be adjusted to a horizontal distribution through rotation when they are distributed up and down, and can ensure connection with the two flexible electrode sheets, thereby ensuring the accuracy of detection.

[0026] The above-described embodiments of the present invention do not constitute a limitation on the protection scope of the present invention. Any modification, equivalent substitution and improvement made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
