Description

Technical Field

[0001] The utility model relates to the technical field of LED packaging, in particular to an LED lamp bead packaging bracket. Background Art

[0002] LED lamp bead packaging technology is an important part of modern lighting technology. The packaging quality directly determines the luminous performance, stability and service life of the LED lamp bead. In the LED lamp bead packaging process, the packaging bracket plays a vital role. It not only supports the LED chip, but also ensures a stable connection between the chip and the electrode.

[0003] When traditional LED lamp bead packaging brackets leave the factory, iron sheets are usually used to fix the positive and negative pins. Although this fixing method ensures the stability of the pins to a certain extent, the iron sheets need to be cut and cleaned after packaging, which increases the complexity and cost of the packaging process. Since the distance between the chip contacts and the connection points is relatively large, longer gold wires are required for connection, which not only increases the amount of gold wire used, but may also affect the performance and reliability of the LED lamp beads. For this reason, we propose an LED lamp bead packaging bracket. Utility Model Content

[0004] The purpose of the utility model is to provide an LED lamp bead packaging bracket to solve the problems raised by the above background technology.

[0005] To achieve the above object, the utility model provides the following technical solutions: an LED lamp bead packaging bracket, comprising an insulating support block, a protrusion is provided on the top surface of the insulating support block, a first pole piece and a second pole piece are bonded to the top surface of the insulating support block, and the first pole piece and the second pole piece are respectively located on both sides of the protrusion on the top surface of the insulating support block;

[0006] The top surfaces of the first pole piece and the second pole piece are both integrally formed with an L-shaped conductive sheet, the top surface of the insulating support block is provided with an LED chip, and a gold wire is connected between the LED chip and the L-shaped conductive sheet.

[0007] Preferably, the insulating support block is made of PVC material.

[0008] Preferably, a U-shaped cardboard is fixedly mounted on one end of the L-shaped conductive sheet, the U-shaped cardboard is made of PVC material, and the LED chip is located between two U-shaped cardboards.

[0009] Preferably, the distance between the inner sides of the two U-shaped card boards appropriately matches the length dimension of the LED chip, and the width dimension of the inner side of the U-shaped card boards appropriately matches the width dimension of the LED chip.

[0010] Preferably, one end of the gold wire is welded to the contact surface of the LED chip, and the other end of the gold wire is welded to the L-shaped conductive sheet.

[0011] Preferably, pins are fixedly mounted on the bottom surfaces of the first pole piece and the second pole piece.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The LED lamp bead packaging bracket adheres the first pole piece and the second pole piece to both sides of the raised portion on the surface of the insulating support block through insulating glue. The raised portion separates and insulates the first pole piece from the second pole piece, so that there is no need to support the pin, the first pole piece, and the second pole piece by arranging an iron sheet on the outside of the pin, thereby eliminating the process of punching the iron sheet after the packaging is completed.

[0014] 2. The LED lamp bead packaging bracket is connected to the first pole piece and the second pole piece respectively through two L-shaped conductive sheets for electrical conduction, so that the gold wire only needs to be connected from the LED chip to the surface of the L-shaped conductive sheet to complete the wiring work, reducing the amount of gold wire used and saving costs.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Embodiment 1

[0020] Please refer to Figure 1-2 As shown, the utility model provides an LED lamp bead packaging bracket, including an insulating support block 1, a convex portion is provided on the top surface of the insulating support block 1, a first pole piece 2 and a second pole piece 3 are bonded to the top surface of the insulating support block 1, and the first pole piece 2 and the second pole piece 3 are respectively located on both sides of the convex portion on the top surface of the insulating support block 1;

[0021] The top surfaces of the first pole piece 2 and the second pole piece 3 are both integrally formed with an L-shaped conductive sheet 5 , the top surface of the insulating support block 1 is provided with an LED chip 7 , and a gold wire 8 is connected between the LED chip 7 and the L-shaped conductive sheet 5 .

[0022] Specifically, by setting an L-shaped conductive sheet 5, when connecting the wires, the L-shaped conductive sheet 5 is directly connected to the contacts of the LED chip 7, and the L-shaped conductive sheet 5 is conductive to the first pole piece 2 or the second pole piece 3, thereby reducing the amount of gold wire 8. The insulating support block 1 supports the first pole piece 2 and the second pole piece 3, and the raised portion of the insulating support block 1 separates the first pole piece 2 and the second pole piece 3.

[0023] Wherein: the insulating support block 1 is made of PVC material.

[0024] Among them: a U-shaped card board 6 is fixedly installed at one end of the L-shaped conductive sheet 5, and the U-shaped card board 6 is made of PVC material.

The spacing between the inner sides of the two U-shaped card boards 6 is appropriately matched with the length dimension of the LED chip 7, and the inner width dimension of the U-shaped card board 6 is appropriately matched with the width dimension of the LED chip 7. The two U-shaped card boards 6 can position the LED chip 7, and when the LED chip 7 is bonded to the top surface of the first pole piece 2, the LED chip 7 can be prevented from being skewed.

[0025] Among them: one end of the gold wire 8 is welded to the contact surface of the LED chip 7, and the other end of the gold wire 8 is welded to the L-shaped conductive sheet 5, and the gold wire 8 plays a conductive effect.

[0026] Wherein: pins 4 are fixedly mounted on the bottom surfaces of the first pole piece 2 and the second pole piece 3 , and the first pole piece 2 and the second pole piece 3 are electrically conductive with two pins 4 respectively.

[0027] Working principle: The utility model is a LED lamp bead packaging bracket. When the bracket is installed, the first pole piece 2 and the second pole piece 3 are bonded to the two sides of the raised part on the surface of the insulating support block 1 by insulating glue. The raised part separates and insulates the first pole piece 2 from the second pole piece 3, so that it is not necessary to support the pin 4, the first pole piece 2, and the second pole piece 3 by arranging an iron sheet outside the pin 4, thereby eliminating the process of punching the iron sheet after the packaging is completed;

[0028] The two L-shaped conductive sheets 5 are connected to the first pole piece 2 and the second pole piece 3 for electrical conduction, so that the gold wire 8 only needs to be connected from the LED chip 7 to the surface of the L-shaped conductive sheet 5 to complete the wiring work, thereby reducing the amount of gold wire 8 and saving costs;

[0029] The LED chip 7 is positioned by the U-shaped card plate 6 connected to the L-shaped conductive sheet 5. When the LED chip 7 is bonded to the top surface of the first pole piece 2, it is not easy to deviate, which facilitates rapid confirmation of the position, ensures chip packaging efficiency, and reduces defective rate.
