Description

Technical Field

[0002] With the advancement of technology, the term "battery" now broadly refers to a small device capable of generating electrical energy, such as a solar cell. The main performance parameters of a battery include electromotive force, capacity, specific energy, and resistance. Using batteries as an energy source provides a stable voltage, stable current, long-term stable power supply, and minimal susceptibility to external influences. Furthermore, batteries are simple in structure, portable, easy to charge and discharge, unaffected by external climate and temperature, and offer stable and reliable performance, playing a significant role in various aspects of modern life.

[0003] However, during the production process of cylindrical batteries, the battery cover and cylindrical shell need to be pre-welded and positioned by welding equipment. In the process of pre-welding and positioning the battery cover and cylindrical shell by welding equipment, the existing welding equipment directly places the battery cover in the preset position at the welding position with the cylindrical shell through a gripper mechanism.

[0004] However, during the process of placing the battery cover by the gripper mechanism, there may be excessive contact with the cylindrical outer shell. Excessive contact will cause damage to the aluminum battery cover and the cylindrical outer shell, resulting in a high scrap rate. Utility Model Content

Figure 8 This is a cross-sectional view from another perspective of the unidirectional flipping feeding mechanism in the battery cover welding device of this application. Figure 9 This is another perspective view of the layered structure of the unidirectional flipping feeding mechanism in the battery cover welding device of this application. (See diagram below.) Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, the unidirectional flipping feeding mechanism 324 includes a feeding body 3241, a bushing 3242 connected to one side wall of the feeding body 3241, a one-way bearing 3243 sleeved inside the bushing 3242, and a motor 22 connected to the one-way bearing 3243. A material receiving groove 3241A is provided at one end of the feeding body 3241, and an adapter groove 3241B is also provided on the side wall of the feeding body 3241. The adapter groove 3241B and the bushing 3242 are respectively located on adjacent side walls of the feeding body 3241. A flexible protective layer 3241C is also provided inside the adapter groove 3241B. The one-way bearing 3243 cooperates with the bushing 3242 and the motor 22 to ensure that the feeding body 3241 can only rotate towards the turntable 24 and cannot rotate away from the turntable 24. The initial position of the feeding body 3241 during operation is vertical. Here, the material receiving groove 3241A is set to load the battery cover and prepare for welding. The adapter groove 3241B is set to match the shape of the cylindrical shell through the matching concave groove, which avoids the feeding body directly hitting the cylindrical shell during the reset process of the unidirectional flip feeding mechanism 324, thus preventing damage to the cylindrical shell and effectively improving reliability.

[0045] Here, the battery cover welding device 30 has a turntable device 20 and a welding device 30 on its worktable 10. A motor 22 is fixed inside the housing 21 of the turntable device 20, and the motor 22 passes through the housing 21. A telescopic top assembly 23 is connected to the motor 22, and a turntable 24 is fixed to the telescopic top assembly 23. A limiting groove 24A is provided on the side wall of the turntable 24 in the telescopic top assembly 23. The limiting groove 24A corresponds to the lifting mechanism 234, and the lifting end of the lifting mechanism 234 can freely extend and retract within the limiting groove 24A. The telescopic top assembly 23 also includes at least one set of extension rods 232 and a support plate 233 connected to the extension rods 232. The lifting mechanism 234 is fixed to the support plate 233. From top to bottom, the sequence is turntable 24, telescopic top assembly 23, and motor 22. The motor 22 drives the telescopic top assembly 23 and turntable 24 synchronously. Rotation; the welding component 32 in the welding device 30 is connected to the first direction telescopic component 31. The first direction telescopic component 31 drives the welding component 32 to telescopically move along the first direction. In the welding component 32, the second direction telescopic mechanism 322 is connected to the support mechanism 321, and the welding mechanism 323 is connected to the second direction telescopic mechanism 322. The one-way flipping feeding mechanism 324 in the welding component 32 has a feeding body 3241, a bushing 3242 connected to one side wall of the feeding body 3241, a one-way bearing 3243 sleeved inside the bushing 3242, and a motor 22 connected to the one-way bearing 3243. A material receiving groove 3241A is provided on one end of the feeding body 3241. During the initial welding positioning process between the battery cover and the cylindrical shell, excessive contact between the battery cover and the cylindrical shell is avoided, effectively reducing the scrap rate.

[0046] To facilitate understanding, the working principle of this application is further described as follows: In the battery cover welding device, during operation, the battery cover is fed into the material receiving tank 3241A via an external feeding device. The material receiving tank 3241A accommodates 1 / 3 of the battery cover to avoid interference during the separation process between the battery cover and the feeding body. After the material receiving tank 3241A senses the battery cover through an external sensor, it sends a signal to an external automatic control switch, causing the first-direction telescopic component 31 to extend along the first direction. After the first-direction telescopic component 31 extends to a preset position, it sends a signal to the external automatic control switch, causing the motor 22 connected to the feeding body 3241 to rotate towards the turntable 24. At this time, under the action of the one-way bearing 3243, the feeding body 3241 rotates at a preset angle. At this time, the battery cover contacts the welding point of the cylindrical shell. During this process, if the rotation angle of the motor 22 is too large, the feeding body adaptively returns to its original position under the action of the one-way bearing 3243, effectively avoiding excessive contact between the battery cover and the cylindrical shell and reducing the scrap rate.

[0047] After the battery cover contacts the welded joint of the cylindrical shell, a signal is sent to the external automatic control switch again, causing the second-direction telescopic mechanism 322 to extend and drive the grounding rod 3231 and welding rod 3232 to approach the welded joint of the battery cover and the cylindrical shell for welding. After welding is completed, a signal is sent to the external automatic control switch through the external sensor, causing the second-direction telescopic mechanism 322 to retract and drive the grounding rod 3231 and welding rod 3232 to reset. Then, the lifting mechanism 234 extends to push one end of the feeding body. Under the action of the one-way bearing 3243, the feeding body rotates away from the turntable 24 until the flexible protective layer 3241C in the adapter groove 3241B contacts the outer wall of the cylindrical shell 21. At this time, the feeding body resets.

[0048] Finally, an external sensor sends a signal to an external automatic control switch, causing the first-direction telescopic component 31 to retract and the welding component 32 to reset, thus completing one welding operation. The external sensor then sends a signal to the external automatic control switch, causing the motor 22 in the turntable device 20 to rotate and drive the turntable 24 to rotate, in preparation for the initial welding positioning of the next battery cover and cylindrical housing 21.
