Technical Field

[0001] This utility model relates to the field of cylindrical battery technology, specifically to a cylindrical battery end cap welding device. Background Technology

[0002] Cylindrical batteries are a type of battery characterized by high capacity, long cycle life, and a wide operating temperature range. They are widely used in solar lighting, lawn lighting, backup power, power tools, and toy models. Cylindrical batteries are mainly classified into different systems, including lithium iron phosphate, lithium cobalt oxide, lithium manganese oxide, cobalt-manganese hybrid, and ternary materials. The casings are available in steel and polymer types. Among these, steel-cased cylindrical lithium iron phosphate batteries are the mainstream product, widely used in various fields due to their high capacity, high output voltage, good charge-discharge cycle performance, stable output voltage, high current discharge capability, electrochemical stability, and safety. Furthermore, cylindrical batteries also offer advantages such as a wide operating temperature range and environmental friendliness.

[0003] When welding the end caps of cylindrical batteries, the cylindrical batteries need to be fixed in place. However, existing cylindrical battery end cap welding equipment is usually not suitable for fixing cylindrical batteries of different sizes. Therefore, it is necessary to customize fixing devices for cylindrical batteries of different sizes, which leads to increased costs. Utility Model Content

[0012] This utility model has the following beneficial effects:

[0013] 1. This cylindrical battery end cap welding equipment, by starting the first motor, causes the positive and negative lead screws to rotate. The positive and negative lead screws drive the sliding block to slide in the fixed shell. The sliding block causes the push arm to rotate around the support base as the fulcrum. During the rotation, the push arm pushes the connecting seat to move. The connecting seat pushes the push block and the fixing plate to move out of the fixed shell, so that the fixing plate gradually approaches the cylindrical battery on the placement plate until the fixing plate touches the cylindrical battery, thus fixing the cylindrical battery. In this way, cylindrical batteries of different sizes can be fixed without the need for customized fixing devices for cylindrical batteries of different sizes, thereby reducing costs.

[0014] 2. This cylindrical battery end cap welding equipment, by starting the first motor, drives the second rotating rod to rotate within the fixed base. The second rotating rod drives the fourth bevel gear, which in turn drives the third bevel gear and the first rotating rod to rotate. Simultaneously, the first rotating rod drives the second bevel gear to rotate, which in turn drives the first bevel gear to rotate. The first bevel gear drives the positive and negative lead screws to rotate within the fixed housing, enabling the fixing mechanism to fix multiple cylindrical batteries at once. This reduces the workload of workers and improves production efficiency. Attached Figure Description

[0029] Furthermore, a support column 4 is fixedly connected to one end of the base 1, and a moving mechanism 5 is provided on the support column 4.

[0035] By adopting the above technical solution, the laser welding head 8 can be moved vertically to weld the cylindrical battery end cap.

[0036] Working principle: When a cylindrical battery is placed on the placement plate 6, the first motor 316 on the fixed base 2 is started. The first motor 316 drives the second rotating rod 315 to rotate within the fixed base 2. The second rotating rod 315 drives the fourth bevel gear 314, which in turn drives the third bevel gear 313 and the first rotating rod 312 to rotate. Simultaneously, the first rotating rod 312 drives the second bevel gear 311 to rotate, which in turn drives the first bevel gear 304 to rotate. The first bevel gear 304 drives the positive and negative lead screw 305 to rotate within the fixed housing 301. The positive and negative lead screw 305 then drives the sliding... The movable block 307 slides within the fixed housing 301, causing it to move towards the center of the forward and reverse lead screw 305. The sliding block 307, via the support base 308, causes the push arm 309 to rotate around the support base 308. During this rotation, the push arm 309 pushes the connecting seat 310 to move. The connecting seat 310 then pushes the push block 306 and the fixed plate 302 to slide within the groove 303 on the fixed housing 301, causing the fixed plate 302 to move outward from the fixed housing 301. This allows the fixed plate 302 to gradually approach the cylindrical battery on the placement plate 6 until it touches the cylindrical battery, at which point the first motor 316 stops. Rotation fixes the cylindrical battery in place by the fixing mechanism 3. Then, the second motor 502 on the first support platform 501 is activated. The second motor 502 drives the first lead screw 503 to rotate within the first support platform 501. The first lead screw 503 then moves one side of the first moving platform 504 within the first support platform 501, causing the other side of the first moving platform 504 to slide on the round rod 508 within the second support platform 507. This causes the first moving platform 504 to move the laser welding head 8 longitudinally. Next, the third motor 505 on the first moving platform 504 is activated. The third motor 505 drives the second... The lead screw 506 rotates on the first moving platform 504, and the second lead screw 506 drives the second moving platform 509 to move within the first moving platform 504, which in turn causes the first moving platform 504 to move the laser welding head 8 laterally. Finally, the fourth motor 510 on the second moving platform 509 is activated, and the fourth motor 510 drives the third lead screw 511 to rotate within the second moving platform 509. The third lead screw 511 drives the moving block 7 to move within the second moving platform 509, which in turn causes the second moving platform 509 to move the laser welding head 8 vertically, allowing the laser welding head 8 to weld the cylindrical battery end cap.
