Description

Technical Field

[0001] The utility model relates to the technical field of laser welding, in particular to a battery shell support plate laser welding dust suction device. Background Art

[0002] Laser welding is an efficient and precise welding method that uses a high-energy-density laser beam as a heat source. Laser welding is one of the important aspects of the application of laser material processing technology. It is mainly used for welding thin-walled materials and low-speed welding. The welding process is a heat conduction type, that is, the laser radiation heats the workpiece surface, and the surface heat diffuses to the inside through heat conduction. By controlling the laser pulse width, energy, peak power, repetition frequency and other parameters, the workpiece is melted to form a specific molten pool. Due to its unique advantages, it has been successfully used in the precision welding of micro and small parts.

[0003] A dust suction device for battery laser welding disclosed in publication number CN116140795A relates to the field of battery production technology. It includes a dust suction body, which is provided with a working hole and a dust suction port. The working hole is located in the middle of the dust suction body. There are multiple dust suction ports, which are evenly arranged around the working hole. A dust suction chamber is formed on the side of the dust suction body that is against the welded workpiece, and the dust suction chamber is connected to the dust suction port and the working hole; the dust suction ports are all connected to dust suction pipes, and the multiple dust suction pipes are finally connected to a dust collector. The dust collector can provide suction, and the smoke generated on the surface of the welded workpiece passes through the dust suction chamber and the dust suction port in turn, and finally the smoke is sucked into the dust collector. The fact that there are multiple dust suction ports evenly arranged around the working hole can make the suction force evenly distributed, alleviating the problem of poor dust suction effect and the smoke floating up and easily adhering to the protective lens of the welding head.

[0004] In response to the above problems, although the reference document alleviates the problem of poor dust suction effect and the problem of smoke and dust easily adhering to the protective lens of the welding head, during the implementation of the welding operation, dust will inevitably be generated during the welding process, and the dust will spread everywhere with the flow of air. Although the welding equipment is equipped with dust suction equipment, after the installation of these equipment, their angles and positions are often set to a fixed state, lacking the necessary flexibility and adjustability. Such a design makes the dust suction device only able to effectively capture dust in specific local locations, and cannot achieve comprehensive coverage of a wider area. Therefore, the absorption range of the dust suction device is relatively limited, which undoubtedly reduces its efficiency in actual work and makes it difficult to fully meet the cleaning needs of the welding operation site.

[0036] Further, such as Figure 1 As shown, the following preferred technical solutions are provided:

[0037] The four corners of the bottom of the workbench 1 are fixedly connected with support blocks 17, and the four support blocks 17 are symmetrically arranged.

[0038] Further, such as Figure 1 and Figure 2 As shown, the following preferred technical solutions are provided:

[0039] A protective pad 18 is fixedly connected to one side of the splint 24. The protective pad 18 is made of rubber. The provision of the protective pad 18 protects the battery housing, reduces the contact between the battery housing and the splint 24, and makes the battery housing less susceptible to damage, thereby extending the service life of the battery housing.

[0040] Working principle: the user places the battery shell on the top of the fixed block 21, and then the user turns the second handle 16, the second handle 16 drives the bidirectional threaded rod 22 to rotate, the bidirectional threaded rod 22 drives the two first threaded blocks 23 to move relative to each other, and the first threaded block 23 drives the clamping plate 24 to move when moving. As the clamping plate 24 continues to move, the protective pad 18 will contact the battery shell, so that the battery shell can be fixed, and then the user can perform laser welding on the battery shell.

[0041] Subsequently, the user can absorb the dust generated during the welding process by starting the dust suction device 10, and start the first motor 5. The output shaft of the first motor 5 drives the threaded rod 6 to rotate. When the threaded rod 6 rotates, it will drive the second threaded block 7 to move, and the second threaded block 7 drives the placement plate 8 to move. When the placement plate 8 moves, it will drive the guide block 15 to slide on the surface of the guide rod 14. At the same time, the placement plate 8 will drive the adjusting mechanism 9 to move, and the adjusting mechanism 9 will drive the dust suction device 10 to move, so that dust at different positions can be absorbed. The user starts the third motor 97. The output shaft of the third motor 97 drives the third short rod 98 to rotate, and the third short rod 98 drives the second bevel gear 99 to rotate, and the second bevel gear 99 drives the first bevel gear 94 to rotate, and the first bevel gear 94 drives the first short rod 93 to rotate, and the first short rod 93 drives the dust suction device 10 to swing left and right, thereby increasing the absorption range.

[0042] The second motor 95 and the third motor 97 are started at the same time, the second motor 95 drives the second short rod 96 to rotate, and the second short rod 96 drives the adjusting block 92 to rotate. At this time, the third motor 97 is started, and the output shaft of the third motor 97 drives the third short rod 98 to rotate, and the third short rod 98 drives the second bevel gear 99 to rotate. Since the first bevel gear 94 is meshed with the second bevel gear 99, the adjusting block 92 can drive the dust collection device 10 and the first bevel gear 94 to adjust the angle through the setting of the first short rod 93 when rotating, thereby increasing the absorption range again.
