AI Technical Summary
In PCBA production, magnets are easily loosened and attracted to each other due to narrow pitch design, resulting in operational risks and glue splashing. Existing jigs cannot effectively solve this problem.
A strong magnet bonding fixture for PCBA was designed. It adopts a base, positioning column, clamping mechanism and top seat structure. The strong magnet is adsorbed by a metal plate. The adsorption force is adjusted by controlling the thickness of the metal plate to ensure one-time clamping with a fixed spacing between the magnets.
The stable fixation of the magnet is achieved, the risk of magnet loosening and glue splashing is reduced, and production safety and efficiency are improved.

Abstract
Description
Technical Field
[0001] The utility model relates to the field of sensor assembly jigs, in particular to a strong magnet bonding jig used on PCBA. Background Art
[0002] The inductive sensor structure contains a magnet, which can detect the position of an object by using the changing strength of the magnetic field.
[0003] In actual production, a full PCBA is composed of 10 or more smaller ones. Magnets are glued to the end faces of each small PCBA using a jig. To save costs, the spacing between the small boards is relatively narrow. This makes it easy for magnets to attract adjacent magnets when they are fixed, causing them to loosen and engage. This can cause glue to splash into eyes, posing a risk to the operator.

[0019] It should also be noted that, in the description of the present invention, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections, direct connections, indirect connections via an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.
[0020] Example:
[0021] like Figures 1 to 2 As shown, according to an overall technical concept of the present invention, a strong magnetic bonding jig for PCBA is provided, comprising:
[0022] The base 1 has a positioning column 11 and a clamping mechanism 12 on its side. The positioning column 11 is used to position the PCBA 100, and the clamping mechanism 12 is used to clamp the PCBA 100 positioned on the positioning column 11.
[0023] The top seat 2 is provided above the base 1. The top seat 2 and the base 1 are detachably fixedly connected. The bottom side of the top seat 2 is provided with multiple groups of spaced steps 21, and the steps 21 are used to place the strong magnet 200. The front side of the top seat 2 is provided with a metal plate 22, and the metal plate 22 is used to attract the strong magnet 200.
[0024] In the assembled state, the multiple mounting positions on the top side of the PCBA 100 are arranged in a one-to-one correspondence with the multiple groups of strong magnets 200 .
[0025] like Figures 1 to 2 As shown, in an exemplary embodiment of the present invention, there are at least two positioning posts 11 , and the positioning posts 11 are arranged in a one-to-one correspondence with the positioning holes on the PCBA 100 .
[0026] like Figures 1 to 2 As shown, in an exemplary embodiment of the present invention, the clamping mechanism 12 adopts a clamping plate, which is detachably arranged on the front side of the base 1 through two locking bolts, and is used to clamp the PCBA 100 positioned on the positioning column 11.

[0028] Therefore, the utility model has the following advantages:
[0029] The strong magnet bonding jig for PCBA proposed in the utility model utilizes the principle of magnetic attraction and selects a metal plate to adsorb the strong magnet. When the spacing between the strong magnets remains unchanged, the magnitude of the adsorption force is controlled by the thickness of the metal plate. By selecting a metal plate of appropriate thickness, multiple strong magnets can be clamped into place at one time, reducing the problem of inaccurate positioning caused by mutual attraction between single clamps.
