Description

Technical Field

[0001] This utility model relates to the field of equipment for LED manufacturing, specifically to a fixing device for plug-in LED wire bonding. Background Technology

[0002] Through-hole LEDs are a traditional form of LED packaging where the leads can be directly inserted into holes in a circuit board for soldering. They are widely used in indicator lights, displays, lighting, and other fields.

[0003] The manufacturing process of plug-in LEDs includes chip bonding, wire bonding, adhesive encapsulation, and lead cutting. Wire bonding, also known as LED wire bonding, is a solid-state bonding process that bonds aluminum wires to the chip electrodes and the lead frame of the support. Because the pins of plug-in LEDs are relatively long, ordinary fixtures cannot be used during wire bonding. Fixtures that can hold plug-in LEDs require manual loading and unloading, and operational errors can damage the pins. Utility Model Content

[0004] This utility model aims to solve the technical problems mentioned in the background section above, and proposes the following technical solutions:

[0005] A fixing device for plug-in LED wire bonding includes a base, a fixing structure A, and a fixing structure B. The base has an LED sliding groove. Fixing structures A and B are respectively fixed to both sides of the LED sliding groove. One side of fixing structure A has a groove containing several springs, one end of which is fitted with a top plate. Fixing structure B is a hollow structure with openings on both sides. Rotating gears are respectively installed at the left and right ends of fixing structure B. A belt is fitted around the outer periphery of the two rotating gears. The base has two motor placement slots, corresponding to the positions of the two rotating gears. A motor is installed in each motor placement slot, and the motor is connected to a rotating rod. One end of the rotating rod is fixedly connected to the rotating gear. A pressure strip is provided around the outer periphery of the belt.

[0006] Preferably, the pressure strip is an elastic structure, and the top plate is interference-fitted with the pressure strip.

[0007] Preferably, the groove is provided with a plurality of partitions, and the plurality of partitions are respectively located between the two springs.

[0008] Preferably, a guide plate is provided between the spring and the top plate, and the guide plate is slidably connected to the partition and the fixed structure A around its perimeter.

[0009] Preferably, the LED chute has an opening at one end with a beveled edge.

[0010] The beneficial effects of this utility model are:

[0011] 1. By setting up LED chutes, top plates, and pressure bars, and using the top plates and pressure bars to clamp the LEDs, and setting the pressure bars to be movable, the LEDs can be moved by the movement of the pressure bars, so as to achieve the purpose of rapid loading and unloading.

[0012] 2. By setting partitions between the springs and guide plates between the top plate and the springs, it is possible to prevent the springs from bending and causing localized top plate depressions.

[0013] 3. By setting one end of the LED chute to have an angled opening, the material can be easily fed in. Attached Figure Description

[0023] Example 1

[0024] Reference Figure 1-4 A plug-in LED wire bonding fixing device includes a base 1, a fixing structure A2, and a fixing structure B3. An LED sliding groove 1-1 is provided on the base 1. Fixing structures A2 and B3 are respectively fixed to both sides of the LED sliding groove 1-1. A groove 2-1 is provided on one side of fixing structure A2, and several springs 2-2 are installed inside the groove 2-1. A top plate 2-3 is provided at one end of each spring 2-2. Fixing structure B3 is a hollow structure with openings on both sides. Rotating gears 4 are respectively installed at the left and right ends of fixing structure B3. Belts 5 are fitted around the outer periphery of the two rotating gears 4. Two motor placement slots 1-2 are provided inside the base 1, and their positions correspond to the positions of the two rotating gears 4. A motor 6 is installed inside the motor placement slots 1-2, and the motor 6 is connected to a rotating rod 7. One end of the rotating rod 7 is fixedly connected to the rotating gear 4. Pressure strips 8 are provided around the outer periphery of the belt 5.

[0025] Preferably, the pressure strip 8 is an elastic structure, and the top plate 2-3 is interference-fitted with the pressure strip 8.

[0026] In actual operation, plug-in LEDs are placed into the LED chute one by one by manual or automatic feeding device. The plug-in LEDs in the LED chute are clamped by the top plate 2-3 and the pressure strip 8. Under the rotation of motor 6, the rotating gear 4 drives the belt 5 to rotate, which can realize the forward movement of plug-in LEDs. A sensor can be set directly below the wire bonding device. When the LED moves to the sensor position, motor 6 stops rotating and then wire bonding is performed. After the wire bonding is completed, motor 6 continues to work, moving the subsequent plug-in LEDs to the wire bonding position. The plug-in LEDs that have completed the wire bonding are unloaded from the other end of LED chute 1-1.

[0027] Compared to modern clamping and fixing structures, this structure makes loading and unloading more convenient, and eliminates the need for workers to insert plug-in LEDs one by one into the clamping device, thus avoiding damage to the pins.

[0028] Example 2

[0029] Reference Figure 3 A number of partitions 9 are provided in the groove 2-1, and the partitions 9 are respectively located between the two springs 2-2. A guide plate 10 is provided between the spring 2-2 and the top plate 2-3. The guide plate 10 is slidably connected to the partitions 9 and the fixed structure A2 around its perimeter. By providing partitions 9 between the springs 2-2 and guide plates 10 between the top plate 2-3 and the springs 2-2, the bending of the springs 2-2 can be prevented, which would cause the top plate 2-3 to be concave in some areas.

[0031] Reference Figure 5 The LED chute 1-1 has an opening at one end with a beveled structure, which facilitates material loading.
