Description

Technical Field

[0001] This utility model relates to a polymer lithium battery tab welding device, belonging to the field of tab welding technology. Background Technology

[0002] Tabs are a raw material for lithium-ion polymer batteries. During the manufacturing process of lithium batteries, tabs need to be welded onto the cover plate to facilitate current conduction. This also effectively prevents short circuits between the metal strip and the aluminum-plastic film and extends the lifespan of the lithium battery.

[0003] The existing patent number CN117123978B describes a polymer lithium battery tab welding device. This device consists of a pair of rotating discs and a pair of placement boxes. A second motor continuously drives the rotating column in one direction to complete the welding operation. Simultaneously, a lifting component moves the rising plate upwards, raising the tabs inside the placement boxes to facilitate subsequent suction cup adsorption. This avoids the need for multiple adjustments to the hydraulic rod's downward distance and ensures the tabs are not damaged due to varying downward pressure. The vacuum suction tube connecting to the vacuum pump is existing technology and will not be discussed further. Workers only enter during tab filling, greatly minimizing health risks. The automated operation effectively improves welding efficiency. The device utilizes the spring force of the vibrating ball and the rotating rod... The device vibrates the second cavity, and the cyclic vibration ensures the detachment of the suction cup. However, while the two rotating disks at the top of the device can rotate the polymer lithium battery, they lack loading and unloading mechanisms. Therefore, during electrode welding, manual loading and unloading of the polymer lithium battery is still required in real time. Vibration during welding is caused by the influence of various driving components, affecting the stability of the polymer lithium battery and the final welding quality. Furthermore, after the pre-set electrodes are used up, they need to be manually refilled one by one, and vibration control of the suction cup is required, increasing the difficulty of operation and the manufacturing cost of the device. This is not conducive to the rapid loading and welding of electrodes. Utility Model Content

[0004] The purpose of this invention is to provide a polymer lithium battery tab welding device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A polymer lithium battery tab welding device includes a welding box, an extension plate, and a welding head. Extension plates are fixedly connected to both the left and right sides of the welding box. A conveyor belt is rotatably connected to the inner side of the welding box and the extension plates. A clamping plate is slidably connected to the outer side of the conveyor belt. The inner end of the clamping plate passes through the conveyor belt. A transmission rod is rotatably connected to the inner end of the clamping plate. A transmission plate is rotatably connected to the inner end of the transmission rod. A fixing ring is fixedly connected to the middle position of the upper front side of the inside of the welding box. A rotating disk is rotatably connected to the inner side of the fixing ring. The rotating disk is rotatably connected to the welding box. Welding heads are fixedly connected to the front and rear sides of the lower end of the rotating disk. Suction cups are sealed to the front and rear sides of the lower end of the welding head.

[0007] Furthermore, a limiting frame is fixedly connected to the outer side of the conveyor belt, and the limiting frame is slidably connected to the clamping plate.

[0008] Furthermore, a top pressure plate is provided at the middle position of the space between the welding box and the conveyor belt. The top pressure plate is fixedly connected to the welding box, and a pressure-bearing roller is rotatably connected to the upper end of the top pressure plate. The pressure-bearing roller is rotatably connected to the transmission plate.

[0009] Furthermore, a fixed telescopic rod is fixedly connected at the middle position of the outer end face of the transmission plate. A spring is provided inside the outer tube of the fixed telescopic rod, and the inner rod of the fixed telescopic rod is fixedly connected to the conveyor belt.

[0010] Furthermore, a drive motor is fixedly connected at the middle position of the upper front side of the welding box, and the output shaft of the drive motor is fixedly connected to the rotating disk.

[0011] Furthermore, the front end of the fixed ring is sealed with an air pump, the rear end of the air pump is sealed with an air guide pipe, the air guide pipe is sealed with the rotating disk, and the air guide pipe is sealed with the suction cup.

[0012] Furthermore, a fixing plate is fixedly connected to the lower front side of the welding box, and a storage frame is provided at the middle position of the upper end of the fixing plate. A lifting slide plate is slidably connected to the lower end of the storage frame. An electric telescopic rod is fixedly connected to the lower end of the fixing plate. The internal movable rod of the electric telescopic rod is slidably connected to the lifting slide plate. Limiting plates are fixedly connected to the left and right sides of the upper end of the fixing plate. The limiting plates are fitted and connected to the storage frame.

[0013] The beneficial effects of this utility model are:

[0014] This invention utilizes a limiting frame to insert polymer lithium batteries from the left end of the welding box. The drive of the conveyor belt rotates the polymer lithium battery, lifting it as the pressure rollers reach the top of the pressure plate. This causes the transmission plate to move upwards, compressing the fixed telescopic rod and spring. Simultaneously, the transmission rod moves the clamping plate inwards, clamping the polymer lithium battery and ensuring its stability during transport. The battery is also relaxed when positioned on the left and right extension plates, facilitating automatic unloading. This invention utilizes the rotation of the drive motor to rotate the disc... The device rotates, and when the welding head is at the front, the air pump provides suction to the front suction cup, allowing the tab to adhere to the lower end of the suction cup. After the rotating disc moves the tab to the rear, gas enters the rear air duct, causing the rear suction cup to lose suction and allowing the rear welding head to weld the tab to the polymer lithium battery. The extension and retraction of the electric telescopic rod moves the lifting slide up and down, continuously lifting the tab. The limiting plate restricts the storage frame and facilitates its replacement, eliminating the need to fill each tab individually. This improves the convenience of tab feeding and replacement, making the device easier to use and reducing manufacturing costs. Attached Figure Description

[0024] Please refer to Example 1 Figures 1-6 This utility model provides a technical solution:

[0025] A polymer lithium battery tab welding device includes a welding box 1, an extension plate 2, and a welding head 9. Extension plates 2 are fixedly connected to both sides of the welding box 1. A conveyor belt 3 is rotatably connected to the inner side of the welding box 1 and the extension plates 2. A clamping plate 4 is slidably connected to the outer side of the conveyor belt 3. The inner end of the clamping plate 4 passes through the conveyor belt 3. A transmission rod 5 is rotatably connected to the inner end of the clamping plate 4. A transmission plate 6 is rotatably connected to the inner end of the transmission rod 5. A limit frame 11 is fixedly connected to the outer side of the conveyor belt 3, and the limit frame 11 is slidably connected to the clamping plate 4. A top pressure plate 12 is provided at the middle position of the space between the welding box 1 and the conveyor belt 3. The top pressure plate 12 is fixedly connected to the welding box 1. A pressure-bearing roller 13 is rotatably connected to the upper end of the top pressure plate 12, and the pressure-bearing roller 13 is rotatably connected to the transmission plate 6. A fixed top pressure plate 12 is located at the middle position of the outer end face of the transmission plate 6. A fixed telescopic rod 14 is connected, and a spring 15 is provided inside the outer tube of the fixed telescopic rod 14. The inner rod of the fixed telescopic rod 14 is fixedly connected to the conveyor belt 3. By setting a limiting frame 11, the polymer lithium battery can be placed into the welding box 1 from the left end. By driving the conveyor belt 3 to rotate, the polymer lithium battery can be moved. After the pressure roller 13 moves to the upper end of the top pressure plate 12, it will be lifted, and the transmission plate 6 will move upward, and the fixed telescopic rod 14 and spring 15 will be compressed. At the same time, the transmission rod 5 can drive the clamping plate 4 to move inward, thereby clamping the polymer lithium battery, so that the lithium battery can remain stable during the transportation process, and the polymer lithium battery can be in a relaxed state when it is at the position of the left and right extension plates 2, so as to facilitate the automatic unloading of the polymer lithium battery.

[0026] Please refer to Example 2 Figure 1 , Figure 4 , Figure 5 and Figure 6The difference between this embodiment and Embodiment 1 is that: a fixed ring 7 is fixedly connected to the middle position of the upper front side inside the welding box 1; a rotating disk 8 is rotatably connected to the inner side of the fixed ring 7; the rotating disk 8 is rotatably connected to the welding box 1; welding heads 9 are fixedly connected to the front and rear sides of the lower end of the rotating disk 8; suction cups 10 are sealed to the front and rear sides of the lower end of the welding head 9; a drive motor 16 is fixedly connected to the middle position of the upper front side of the welding box 1; and the output shaft of the drive motor 16 is fixedly connected to the rotating disk 8. The front end of the fixed ring 7 is sealed with an air pump 17, and the rear end of the air pump 17 is sealed with an air guide pipe 18. The air guide pipe 18 is sealed with the rotating disc 8 and with the suction cup 10. A fixed plate 19 is fixedly connected to the lower front end of the welding box 1. A storage frame 20 is provided at the middle of the upper end of the fixed plate 19. A lifting slide plate 21 is slidably connected to the lower end of the storage frame 20. An electric telescopic rod 22 is fixedly connected to the lower end of the fixed plate 19. The electric telescopic rod 22 is internally... The movable rod is slidably connected to the lifting slide plate 21. Limiting plates 23 are fixedly connected to both the left and right sides of the upper end of the fixed plate 19. The limiting plates 23 are fitted to the storage frame 20. The rotation of the drive motor 16 causes the rotating disk 8 to rotate. When the welding head 9 is at the front, the air pump 17 provides suction to the front suction cup 10, allowing the electrode tab to adhere to the lower end of the suction cup 10. After the rotating disk 8 moves the electrode tab to the rear end, gas enters the rear air duct 18 to facilitate the rear suction... The disk 10 loses its suction, allowing the welding head 9 on the rear side to weld the tabs onto the polymer lithium battery. The extension and retraction of the electric telescopic rod 22 drives the lifting slide plate 21 to move up and down, continuously lifting the tabs. The limiting plate 23 restricts the storage frame 20, making it easier to replace. There is no need to fill each tab into the storage frame 20 individually, improving the convenience of feeding and replacing the tabs, making the device easier to use, and reducing the manufacturing cost of the device.

[0027] The working principle of this utility model is as follows: When in use, the limiting frame 11 allows the polymer lithium battery to be placed from the left end of the welding box 1. Driving the conveyor belt 3 causes the polymer lithium battery to move. After the pressure roller 13 moves to the top of the pressure plate 12, it is lifted, causing the transmission plate 6 to move upwards and compressing the fixed telescopic rod 14 and spring 15. Simultaneously, the transmission rod 5 drives the clamping plate 4 to move inwards, thus clamping the polymer lithium battery and ensuring its stability during transport. When the polymer lithium battery is positioned at the left and right extension plates 2, it is in a relaxed state, facilitating automatic unloading. The rotation of the drive motor 16 rotates the disc... The rotating disc 8 can rotate. When the welding head 9 is in the front position, the air pump 17 provides suction to the front suction cup 10, allowing the electrode to be adsorbed onto the lower end of the suction cup 10. After the rotating disc 8 moves the electrode to the rear end, gas enters the rear air duct 18, causing the rear suction cup 10 to lose suction and allowing the rear welding head 9 to weld the electrode onto the polymer lithium battery. The extension and retraction of the electric telescopic rod 22 can drive the lifting slide plate 21 to move up and down, so as to continuously lift the electrode. The setting of the limiting plate 23 restricts the storage frame 20 and facilitates the replacement of the storage frame 20. It is not necessary to fill the storage frame 20 with electrode one by one, which improves the convenience of electrode feeding and replacement, makes the device easier to use, and reduces the manufacturing cost of the device.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
