Problems solved by technology
[0003] The existing welding method of the protective circuit module and the ceramic sensitive element is to use a hand-held protective circuit module and the ceramic sensitive element, place the FPC cable at the corresponding welding position, and then use welding equipment for welding, so that the protective circuit module and the ceramic sensitive The instability of the components will cause movement during the welding process, which will bring difficulties to the welding, and it is easy to weld defective products. The welding speed is slow and the efficiency is low. The labor intensity of the staff is high. Solder paste needs to be melted to solder, and the existing soldering method is complicated

The invention relates to the technical field of manufacture for sensors, in particular to a sensor welding tool which comprises a base, supports and a bearing cover plate. The supports are arranged on the base, the bearing cover plate is arranged on the supports and is supported by the supports, a heating device which penetrates the bearing cover plate is arranged above the base and comprises a heat-transfer guide block and a heater, the heat-transfer guide block is provided with a bearing surface and is heated by the heater, an accommodating groove is formed in the bearing cover plate and is positioned on one side of the heat-transfer guide block, and a sucking device is arranged between the accommodating groove and the heat-transfer guide block. The sensor welding tool has the advantages that solder paste at a weld point of a ceramic sensitive element can be quickly melted, a circuit protecting module, the ceramic sensitive element and an FPC (flexible printed circuit) flat cable can be prevented from moving in a welding procedure, the welding quality is guaranteed, the welding efficiency is improved, and the labor intensity of workers is reduced.
Description
technical field [0001] The invention relates to the technical field of sensor production, in particular to a sensor welding tool. Background technique [0002] The sensor includes a shell, a protective circuit module in the shell, and a sensor sensitive element connected to the wire of the protective circuit module. The sensor sensitive element is made of ceramic material, and the protective circuit module and the sensitive element are connected by FPC cables. There are welding points on the ceramic sensitive element, and the FPC cable is welded to the welding point; after the protection circuit module and the ceramic sensitive element are welded, they are assembled in the housing to form a sensor. [0003] The existing welding method of the protective circuit module and the ceramic sensitive element is to use a hand-held protective circuit module and the ceramic sensitive element, place the FPC cable at the corresponding welding position, and then use welding equipment for ...
