Description

Technical Field

[0001] This utility model relates to the field of LED manufacturing, specifically to a plug-in LED lead cutting machine. Background Technology

[0002] Lamp LEDs are a traditional LED packaging method where pins are directly inserted into a circuit board (PCB) for soldering. They are widely used in indicator lights, displays, lighting, and automotive electronics. Lamp LEDs are characterized by having relatively long pins, with the two pins being of different lengths, representing the positive and negative terminals respectively.

[0003] In the process of through-hole LED packaging, the lead cutting process is a key step in the post-packaging process, which directly affects the electrical performance, mechanical stability and compatibility of the product with end applications. Existing lead cutting machines cut the leads to the required length by placing the through-hole LED in the corresponding position and then pressing down the cutter. Generally, the above operation needs to be performed twice, and the positions of the through-hole LEDs are different in the two operations, in order to cut the leads to different lengths.

[0004] This method is not only inefficient, but also requires that if the pin is placed in the wrong position, the pin length will not meet the set value. Utility Model Content

[0005] This utility model aims to solve the technical problems mentioned in the background section above, and proposes the following technical solutions:

[0006] A plug-in LED lead-cutting machine includes a lead-cutting platform, a lead-cutting roller, a stepper motor, and a conveyor belt. The lead-cutting platform is provided with an LED placement slot, and a conveyor belt groove is provided in the middle of the LED placement slot. The conveyor belt is installed in the conveyor belt groove. A motor slot is provided on one side of the lead-cutting platform. Two lead-cutting roller connecting posts are provided on the lead-cutting platform. The lead-cutting roller is installed between the two lead-cutting roller connecting posts and is rotatably connected to the lead-cutting roller connecting posts. One end of the lead-cutting roller passes through the lead-cutting roller connecting post and is connected to a driven wheel. The stepper motor is fixedly installed in the motor slot. A driving wheel is connected to the stepper motor. A belt is fitted around the outer periphery of the driven wheel and the driving wheel. A positive cutter and a negative cutter are provided on the outer periphery of the lead-cutting roller.

[0007] Preferably, the positive electrode cutter and the negative electrode cutter are arranged alternately.

[0008] Preferably, the cutting roller is provided with a pressing strip.

[0009] Preferably, one end of the pressing strip is provided with a rubber pad.

[0010] Preferably, one end of the LED placement slot is provided with a lamp bead slot.

[0011] The beneficial effects of this utility model are:

[0012] 1. By using a cutting roller to replace the traditional cutting method, the cutting roller method can cut the shape in one go without repeated cutting, which can improve the efficiency of the cutting operation.

[0013] 2. By setting a pressing strip, the plug-in LED can be fixed in place, preventing the plug-in LED from shifting or moving during lead cutting, thus avoiding the problem of the lead length not matching the expectation.

[0014] 3. Use LED slots to place LED beads to prevent the height difference between the LED beads and the pins from forming a gap below the pins. This prevents the pins from bending when the cutter presses down on the plug-in LEDs. Attached Figure Description

[0024] Example 1

[0025] Reference Figs. 1-3 A plug-in LED lead cutting machine includes a lead cutting platform 1, a lead cutting roller 2, a stepper motor 3, and a conveyor belt 4. The lead cutting platform 1 is provided with an LED placement slot 1-1, and a conveyor belt groove 1-2 is provided in the middle of the LED placement slot 1-1. The conveyor belt 4 is installed in the conveyor belt groove 1-2. A motor slot 1-3 is provided on one side of the lead cutting platform 1. Two lead cutting roller connecting posts 5 are provided on the lead cutting platform 1. The lead cutting roller 2 is installed between the two lead cutting roller connecting posts 5 and is rotatably connected to the lead cutting roller connecting posts 5. One end of the lead cutting roller 2 passes through the lead cutting roller connecting post 5 and is connected to a driven wheel 6. The stepper motor 3 is fixedly installed in the motor slot 1-3. A driving wheel 7 is connected to the stepper motor 3. A belt 8 is fitted around the outer periphery of the driven wheel 6 and the driving wheel 7. A positive cutter 9 and a negative cutter 10 are provided around the outer periphery of the lead cutting roller 2.

[0026] Preferably, the positive electrode cutter 9 and the negative electrode cutter 10 are arranged alternately, with a negative electrode cutter 10 distributed between two positive electrode cutters 9 and a positive electrode cutter disposed between two negative electrode cutters 10, and the widths of the positive electrode cutter 9 and the negative electrode cutter 10 are the same.

[0027] In actual operation, the feeding device transfers the plug-in LED to the LED placement slot 1-1 on the cutting platform 1. The conveyor belt 4 will drive the plug-in LED to continue moving until it moves to the center of the LED placement slot 1-1. Then the stepper motor 3 starts and drives the cutting roller 2 to rotate. The positive cutter 9 and the negative cutter 10 located on the cutting roller 2 cut out positive and negative leads of different lengths from the two legs of the plug-in LED.

[0028] After the cutting is completed, the stepper motor 3 drives the cutting roller 2 back to the position before cutting, and the conveyor belt 4 continues to work, continuing to move the plug-in LED for unloading.

[0029] Using a cutting roller for cutting feet allows for one-time cutting without the need for repeated cutting, thus improving the efficiency of the cutting operation.

[0030] Example 2

[0031] Referring to the figure, a pressing strip 11 is provided on the cutting roller 2. A rubber pad 12 is provided at one end of the pressing strip 11. The pressing strip is located on one side of the negative electrode cutter 10. By setting the pressing strip 11, the plug-in LED can be fixed, and the problem of the plug-in LED shifting or moving during the cutting process, which would cause the pin length to be inconsistent with the expectation, can be avoided.

[0032] Example 3

[0033] Referring to the figure, an LED placement slot 13 is provided at one end of the LED placement slot 1-1. The LED is placed through the LED slot 13 to prevent the LED from bending when the cutter presses down on the plug-in LED because the LED is too high, resulting in a height difference between the pin and the LED.
