Description

Technical Field

[0001] This application relates to the field of fixtures, and more specifically, to a miniLED fixture. Background Technology

[0002] In the miniLED display module production process, after the back IC components are mounted and soldered, specific base fixtures are required for the IC component layout during operation. The size and IC layout design of each product are quite different.

[0003] A search revealed that Chinese patent CN115570233A discloses a miniLED circuit board clamping fixture. This device uses a first spring to move the front and back connecting blocks to opposite sides, allowing the connecting blocks to drive the first clamping block to clamp the front and back of the miniLED circuit board placed at the clamping structure. By rotating the second handle, the threaded rod can be rotated, allowing the second clamping block to move to the bottom. This, in conjunction with the clamping structure, can clamp the miniLED circuit board. The rubber pads provide protection for the miniLED circuit board.

[0004] The aforementioned device requires adjustment of the clamping structure's position when fixing and disassembling the circuit board, resulting in low fixing efficiency. Therefore, we propose a miniLED fixing fixture. Utility Model Content

[0016] 3. Beneficial effects

[0017] Compared with the prior art, the beneficial effects of this application are:

[0018] 1) By opening a through hole in the middle of the support column, when the circuit board is placed on the support column, a pressure difference can be formed on both sides of the circuit board by means of a negative pressure mechanism to fix the circuit board on the support column; when it is necessary to remove the circuit board, the negative pressure mechanism can be stopped to release the fixation of the circuit board.

[0019] 2) By setting the plug and support column to cooperate, this application can adjust the installation position of the plug and support column according to the size of the circuit board and the layout of IC components, so as to fix different circuit boards, adapt to the production rhythm of rapid updates of electronic products, and reduce the cost of opening fixtures.

[0020] 3) By setting a limiting rod on the support column, this application can fix the limiting rod with the help of the plug and the limiting cap, so as to prevent the support column from rotating during use and affecting the support and fixing effect of the support column on the circuit board.

[0026] The technical solution of this application will now be clearly and completely described in conjunction with the accompanying drawings.

[0027] Please see Figure 1 and Figure 2 This application provides a technical solution:

[0028] A miniLED fixing fixture includes a base 1, with a cavity 101 inside the base 1. An exhaust port 102 is provided on one side of the base 1, and the exhaust port 102 communicates with the cavity 101. Multiple negative pressure holes 103 are provided on the upper surface of the base 1, and the negative pressure holes 103 communicate with the cavity 101. Multiple plugs 2 and support columns 3 are provided on the upper surface of the base 1. The plugs 2 and support columns 3 are inserted and matched with the negative pressure holes 103. A through hole 301 is provided in the middle of the support column 3.

[0029] Users can insert a specified number of support pillars 3 into the negative pressure holes 103 according to the size of the circuit board and the layout of the IC components, and insert plugs 2 into the remaining negative pressure holes 103. The support pillars 3 have various heights, which users can select according to their needs. By placing the circuit board on the support pillars 3 and connecting it to the exhaust port 102 using the negative pressure mechanism, a negative pressure is created in the cavity 101, which can be used to fix the circuit board, facilitating maintenance. When it is necessary to remove the circuit board, the air extraction from the cavity 101 can be stopped, allowing the circuit board to be easily removed.

[0030] Preferably, the negative pressure holes 103 are arranged in rows and columns, and the spacing between two adjacent negative pressure holes 103 in the horizontal or vertical direction is the same.

[0031] Preferably, the plug 2 is threadedly connected to the negative pressure hole 103, and a limit cap 201 is fixedly connected to the upper part of the plug 2. The diameter of the limit cap 201 is larger than the diameter of the negative pressure hole 103.

[0032] like Figure 3 and Figure 4As shown, the lower part of the support column 3 is provided with a threaded connection part 302, and the support column 3 is threadedly connected to the negative pressure hole 103 through the threaded connection part 302. A limit rod 303 is fixedly connected to the lower part of the support column 3. The limit rod 303 is perpendicular to the support column 3, and the length of the limit rod 303 is greater than the distance between two adjacent negative pressure holes 103 in the horizontal or vertical direction. A U-shaped groove 304 is opened at the end of the limit rod 3 away from the support column 3, and the width of the U-shaped groove 304 is not less than the diameter of the negative pressure hole 103. When installing the support column 3, the limit rod 303 can be moved to the adjacent negative pressure hole 103. By installing the plug 2 into the negative pressure hole 103 and fixing the limit rod 303 with the limit cap 201, the stability of the support column 3 can be effectively increased, and the rotation of the support column 3 can be prevented, which would affect the support and fixation effect on the circuit board.
