Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of electronic assembly, and in particular to an antenna board welding tool. Background Art
[0002] The traditional antenna board welding method is to weld two layers of antenna boards, and then use welding tools to fix the antenna boards and then weld them. That is, the antenna board is placed between the upper aluminum alloy pressure plate and the lower aluminum alloy pressure plate, and the upper aluminum alloy pressure plate and the lower aluminum alloy pressure plate are fixed with screws to press the antenna board, and then the antenna board is welded. When welding using the traditional antenna board welding method, long-term high temperature can easily cause the welding tooling to deform, resulting in gaps between the antenna boards. After welding, large areas of voids appear between the antenna boards, affecting the product's technical indicators and welding quality. In addition, the assembly process of the traditional welding tooling is cumbersome, which reduces the overall welding efficiency and is not conducive to large-scale production.

[0009] Furthermore, the antenna plate welding tool also includes a positioning device cover plate and a clamping device cover plate; the positioning device cover plate is connected to the positioning device, and the clamping device cover plate is connected to the clamping device.

The positioning device of the antenna board welding tooling is made of high-temperature resistant non-metallic material, which can prevent the continuous high temperature during the welding process from causing deformation of the positioning device; the clamping device is also made of high-temperature resistant non-metallic material, which can prevent the continuous high temperature during the welding process from causing the clamping device to move and deform, ensuring that the antenna board will not be damaged during the clamping process; and the clamping device and the positioning device are magnetically connected through a samarium cobalt magnet, replacing the traditional method of fixing with screws. The antenna board is pressed by suction, providing a stable clamping force for the antenna board during the welding process, avoiding the cumbersome steps of screw clamping.
