Description

Technical Field

[0001] This utility model relates to the field of welding technology, and in particular to a welding crimping tool with a dust extraction function. Background Technology

[0002] In existing welding processes, especially during the welding of copper busbars to the output electrodes of pouch cells, there is a problem of incomplete removal of foreign matter from the welding surface. The traditional method involves using an air gun to clean the welding surface, but this method often fails to completely remove foreign matter, leaving it in the narrow spaces or gaps of the cell or module. Furthermore, the welding device and the air gun are two separate pieces of equipment, requiring separate operations, which significantly reduces production efficiency and increases operational complexity.

[0003] More seriously, because the welding nozzle and the dust extraction component are separate in traditional methods, it is impossible to clean up foreign objects generated during the welding process in a timely manner. This often leads to welding defects, such as burn-through or explosion of the output electrode and connecting copper busbar of the pouch cell. In module production, a module typically contains more than a dozen cells. If even one cell is defective, the entire module must be scrapped, which undoubtedly increases production costs significantly and seriously affects the product yield. Utility Model Content

[0004] The purpose of this invention is to provide a welding pressing fixture with a dust-collecting function, so as to realize the integrated structure of the welding nozzle and the dust-collecting component, thereby cleaning up foreign objects generated during the welding process in a timely manner.

[0005] This utility model is achieved using the following technical solution: a welding crimping fixture with a dust suction function, characterized in that it includes a connector, the connector having a dust suction channel, welding crimping nozzles and suction nozzles connected to both ends of the connector, the suction nozzles being connected to a vacuum cleaner suction pipe, the welding crimping nozzles having a welding head interface, the welding head interface passing through the welding crimping nozzles and communicating with the dust suction channel, the welding head being inserted into the welding head interface and welding being performed on the crimping surface below the welding crimping nozzles, and during the welding process, the vacuum cleaner promptly sucks out the debris and foreign objects generated during the welding process from the welding point through the suction nozzles and the dust suction channel.

[0006] Furthermore, the connector includes a dust-collecting upper cover and a dust-collecting lower cover, which are bolted together, forming a dust-collecting channel between them.

[0007] Furthermore, the welding nozzle is provided with a dust suction port, which connects to the dust suction channel.

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

[0009] Furthermore, the dust suction cover is provided with a welding nozzle mounting plate, and the welding nozzle is bolted to the welding nozzle mounting plate.

[0010] Furthermore, the welding nozzle is provided with a limiting protrusion, and the dust suction cover is provided with a baffle. The baffle and the welding nozzle mounting plate form a mounting groove, and the limiting protrusion is inserted into the mounting groove to form an embedded limiting structure.

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

[0012] The welding and pressing fixture with dust extraction function described in this utility model has the following advantages:

[0013] 1. The welding nozzle and suction components are integrated into one component, reducing the number of parts, lowering material costs, and using screws for fixing, making assembly more convenient;

[0014] 2. Integrate the upper and lower dust collection covers on the welding nozzle to ensure that foreign objects can be sucked out by the vacuum cleaner in a timely manner after welding is completed;

[0015] 3. The upper and lower dust collection covers work together to form an air intake and exhaust channel, ensuring that foreign objects are directed into the vacuum cleaner through this channel;

[0016] 4. The welding nozzle and the dust suction cover are fixed by screws and an embedded limiting structure to ensure the reliability of their connection during the pressing process of the laser welding head, while meeting the pressure requirements. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0024] like Figure 1-3 As shown, a welding crimping fixture with a dust-collecting function includes a connector with a dust-collecting channel 21 inside. Welding nozzles 1 and suction nozzles 4 are connected to both ends of the connector, respectively. The suction nozzle 4 is connected to a vacuum cleaner hose. A welding head interface 13 is provided on the welding nozzle 1, which passes through the welding nozzle 1 and connects to the dust-collecting channel 21. The welding head is inserted into the welding head interface 13 and welded on the crimping surface below the welding nozzle 1. During welding, the vacuum cleaner promptly removes debris and foreign objects generated during the welding process from the weld joint through the suction nozzle 4 and the dust-collecting channel 21. A sealing ring 5 is also provided between the connector and the suction nozzle 4 to prevent foreign objects from falling from the connection point.

[0025] The connector includes a dust suction upper cover 2 and a dust suction lower cover 3, which are bolted together, forming a dust suction channel 21 between them.

[0026] The welding nozzle 1 is provided with a dust suction port 12, which is connected to the dust suction channel 21.

[0027] There are two suction ports 12. The front end of the suction channel 21 is divided into two channels by a diverter block. The two channels are respectively connected to the two suction ports 12.

[0028] The dust collection cover 2 is equipped with a welding nozzle mounting plate 22, and the welding nozzle 1 is bolted to the welding nozzle mounting plate 22. The welding nozzle 1 is also provided with a limiting protrusion 11, and the dust collection cover 2 is also provided with a baffle 23. A mounting groove is formed between the baffle 23 and the welding nozzle mounting plate 22, and the limiting protrusion 11 is inserted into the mounting groove to form an embedded limiting structure. During the downward pressing process, when the welding nozzle 1 touches the output electrode of the soft-pack battery cell, a reaction force will occur. Through the added embedded limiting structure, the welding nozzle 1 is effectively supported on both the upper and lower surfaces under the action of the dust collection cover 2 and the dust collection cover 3. This prevents fatigue or even damage between the welding nozzle mounting plate 22 and the main structure of the dust collection cover 2.
