Description

Technical Field

[0001] The invention relates to the technical field of welding, and in particular to a welding crimping tool with a dust suction function. Background Art

[0002] In the existing welding process, especially in the welding process of connecting the copper busbar and the output pole of the soft-pack battery cell, there is a problem of incomplete cleaning of foreign matter on the welding surface. The traditional treatment method is to clean the welding surface with an air gun device, but this method often cannot completely remove foreign matter, and foreign matter will be left in the narrow space or gap of the battery cell or module. In addition, the welding device and the air gun device are two independent devices and need to be operated in two steps, which not only greatly reduces the production efficiency of the product, but also increases the complexity of the operation.

[0003] What is more serious is that, because the welding nozzle and the dust collection component are separated in the traditional method, it is impossible to clean up the foreign matter generated during the welding process in time. This often leads to poor welding during the welding process, such as the risk of welding penetration and welding explosion between the output pole of the soft-pack battery cell and the connecting copper busbar. In module production, a module usually contains more than a dozen batteries. If one of the batteries is defective, the entire module needs to be scrapped, which undoubtedly greatly increases the production cost and seriously affects the yield rate of product production. Summary of the invention

[0004] The purpose of the present invention is to provide a welding crimping tool with a dust suction function to realize an integrated structure of a welding crimping nozzle and a dust suction component, thereby timely cleaning foreign matter generated during the welding process.

[0005] The present invention is implemented by adopting the following technical scheme: a welding crimping tool with a dust suction function, characterized in that it includes a connecting piece, a dust suction channel is arranged in the connecting piece, a welding nozzle and a suction nozzle are respectively connected to the two ends of the connecting piece, the suction nozzle is connected to the vacuum cleaner suction pipe, a welding head interface is arranged on the welding nozzle, the welding head interface passes through the welding nozzle and is connected to the dust suction channel, the welding head is inserted into the welding head interface and welding is performed on the crimping surface below the welding nozzle, and during the welding process, the vacuum cleaner promptly sucks out the debris and foreign matter generated by the welding process from the welding point through the suction nozzle and the dust suction channel.

[0006] Furthermore, the connecting member includes an upper dust suction cover and a lower dust suction cover, and the upper dust suction cover and the lower dust suction cover are connected by bolts, and a dust suction channel is formed between the upper dust suction cover and the lower dust suction cover.

[0007] Furthermore, a dust suction interface is provided on the welding nozzle, and the dust suction channel is connected through the dust suction interface.

[0008] Furthermore, there are two dust suction interfaces, and the front end of the dust suction channel is divided into two channels by a diverter block, and the two channels are connected to the two dust suction interfaces respectively.

[0009] Furthermore, a welding nozzle mounting plate is provided on the dust suction upper cover, and the welding nozzle is connected to the welding nozzle mounting plate by bolts.

[0010] Furthermore, a limiting protrusion is provided on the welding nozzle, and a baffle is provided on the dust collection cover. A mounting groove is formed between the baffle and the welding nozzle mounting plate, and the limiting protrusion is inserted into the mounting groove to form an embedded limiting structure.

[0011] Furthermore, a welding head interface is provided on the welding nozzle, and is respectively connected to two dust suction interfaces.

[0012] The welding crimping tool with dust suction function described in the present invention has the following beneficial effects: 1. The welding nozzle and the dust collection parts are integrated into one component, which reduces the number of parts and material costs. It is fixed with screws, making assembly more convenient; 2. The upper and lower dust suction covers are integrated on the welding nozzle to ensure that foreign matter here can be sucked out by the vacuum cleaner in time when welding is completed; 3. The upper dust cover and the lower dust cover cooperate to form an air suction and sewage discharge channel to ensure that foreign matter is discharged into the vacuum cleaner in a directional manner through this channel; 4. The welding nozzle and the dust collection cover are fixed by screws and embedded limit structures to ensure the reliability of their connection during the downward pressure of the laser welding head and meet the pressure requirements.
