[0024] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application usually described and marked in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present application.

[0025] The utility model discloses a welding pin fixture for an LED lamp board, which is mainly used in the scenario where the pin feet and pin needles of the LED lamp board are small in size and there is a certain degree of difficulty in welding.

[0026] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 , a welding pin fixture for an LED lamp board, comprising a base plate 1, and further comprising:

[0027] Opening and closing mechanism for easy use of the jig;

[0028] A fixing mechanism for further stabilizing the pin;

[0029] The top outer wall of the bottom plate 1 is provided with a plurality of holes 4, one side outer wall of the bottom plate 1 is fixedly connected with two mounting blocks, the outer walls on the opposite sides of the two mounting blocks are movably connected with the same pressing plate 2 through a rotating shaft, the top outer wall of the pressing plate 2 is provided with four openings 3 distributed at equal distances, and the bottom outer wall of the pressing plate 2 is fixedly provided with three gaskets 7;

[0030] The fixing mechanism includes a plurality of cross slots 8 opened inside the base plate 1, four clamping blocks 9 and four return springs 10 are arranged inside the cross slot 8, an arc-shaped notch is opened at the front end of the clamping block 9, the position of the opening 3 corresponds to the position of the hole 4, the hole 4 is located in the central position of the cross slot 8, one end of the return spring 10 is connected to the outer wall of one side of the clamping block 9, and the end of the return spring 10 away from the clamping block 9 is connected to the inner wall of the cross slot 8.

[0031] Among them, the four arc-shaped notches on the four clamping blocks 9 form a circular structure, and the diameter of the circular structure is smaller than the diameter of the hole 4, which is used to clamp and fix the pin needle. At the same time, the top of the arc-shaped notch on the clamping block 9 is set as an inclined structure to ensure that the pin needle is smoothly squeezed into the middle of the four clamping blocks 9.

[0032] Furthermore, the bottom outer wall of the bottom plate 1 and the bottom outer wall of the pressing plate 2 are made of rubber material, which can reduce damage to the contact piece and increase the friction with the contact piece, thereby improving the fixing effect.

[0033] Furthermore, the gasket 7 on the pressing plate 2 leaves space for placing the pin contact sheet.

[0034] It should be noted that the diameter and depth of the hole 4 are compatible with the diameter and length of the pin.

[0035] During specific use, the pin contact sheet is placed on the bottom plate 1, and then the pin needle is inserted into the contact sheet in alignment with the hole 4. During the insertion of the pin needle into the hole 4, the pin needle squeezes the four clamping blocks 9, and the clamping blocks 9 clamp and fix the pin needle under the action of the reset spring 10. Then, the pressure plate 2 is closed, and the opening and closing mechanism is used to fix the pressure plate 2 and the bottom plate 1, so that the pressure plate 2 presses and fixes the contact sheet, and finally the pin foot is welded from the opening 3.

[0036] Reference Figure 2 In a preferred embodiment, the opening and closing mechanism includes three magnets 5 fixedly installed on the top outer wall of the bottom plate 1 at equal distances, and three iron blocks 6 are installed on the bottom outer wall of the pressure plate 2, and the positions of the three iron blocks 6 correspond to the positions of the three magnets 5 respectively.

[0037] Specifically, after the pin is fixed, the pressing plate 2 is closed, and the magnet 5 on the bottom plate 1 attracts the iron block 6, thereby fixing the pressing plate 2 and the bottom plate 1. After welding is completed, the pressing plate 2 can be directly opened, which is convenient to open and close.

[0038] Working principle: When in use, place the pin contact sheet on the bottom plate 1, and then align the pin needle with the hole 4 to insert the pin needle into the contact sheet. During the process of inserting the pin needle into the hole 4, the pin needle squeezes the four clamping blocks 9. Under the action of the reset spring 10, the clamping blocks 9 clamp and fix the pin needle. Then close the pressure plate 2, the magnet 5 on the bottom plate 1 attracts the iron block 6, the pressure plate 2 presses and fixes the contact sheet, and finally the pin foot is welded from the opening 3.

[0039] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited to this. The replacement can be a replacement of part of the structure, device, method step, or a complete technical solution. Equivalent replacement or change based on the technical solution of the utility model and its utility model concept should be included in the protection scope of the utility model.
