[0002] With the rapid development of new energy vehicles, the performance and safety of lithium-ion batteries, as one of their core components, have become a hot topic of research. In the manufacturing process of lithium-ion batteries, tab welding is an important link, which directly affects the performance and safety of the battery.

[0003] Semi-automatic welding of lithium battery tabs has high flexibility and saves production costs. It is widely used in small and medium-sized enterprises with not particularly large production demands or limited budgets. The existing semi-automatic welding of lithium battery tabs is usually done by workers placing the lithium battery on a workbench, pressing and fixing the lithium battery tabs on the lithium battery, and then starting the welding table to weld the tabs on the lithium battery electrodes. However, since the tabs need to be pressed and fixed by the workers during welding, injuries to the workers may occur, which is quite dangerous.

[0004] Therefore, a lithium-ion battery tab welding device is now developed that can assist in pressing and fixing the battery tab during the lithium-ion battery tab welding process to avoid injuries to workers. Utility Model Content

DETAILED DESCRIPTION

[0017] The utility model is further described below in conjunction with the embodiments shown in the accompanying drawings.

[0018] A lithium-ion battery tab welding device, such as Figure 1-Figure 3As shown, it includes a workbench 1, a protective cover 2, a revolving door 3, a trackless cylinder 4, a first guide rod 5, a slider 6, an electric push rod 7, a welding table 8, a vacuum tube 9, a limiting frame 10, a second guide rod 11, a sleeve 12, a sliding frame 13, a telescopic spring 14 and a fixing strip 15. The upper side of the workbench 1 is connected to the protective cover, the front side of the protective cover is rotatably connected to the revolving door 3, and the revolving door 3 is provided with a handle for easy opening. The inner rear wall of the protective cover 2 is connected to the trackless cylinder 4, and the inner rear wall of the trackless cylinder 4 is also connected to the first guide rod 5. The trackless cylinder 4 is slidably connected to the slider 6, and the slider 6 is slidably connected to the first guide rod 5. The slider 6 is connected to the electric push rod 7, and the telescopic end of the electric push rod 7 is connected to the welding table 8. A dust suction pipe 9 is also connected to the telescopic end of the electric push rod 7, and the dust suction pipe 9 passes through the protective cover 2. A limiting frame 10 is connected to the upper side of the rear portion of the workbench 1, and second guide rods 11 are connected to the upper sides of the left and right portions of the workbench 1. The left and right portions of the workbench 1 are slidably connected with front and rear sleeves 12, a sliding frame 13 is connected between the front sleeves 12, and a sliding frame 13 is also connected between the rear sleeves 12. The sliding frames 13 are all slidably connected to the second guide rod 11, and the sleeves 12 are all slidably connected to the adjacent sliding frames 13. Telescopic springs 14 are connected between the sleeves 12 and the connected sliding frames 13, and five fixing bars 15 are slidably connected between the sliding frames 13, and soft pads are provided on the fixing bars 15 to avoid crushing the pole ears.

[0019] When using the utility model, first place the workbench 1 in the lithium-ion battery pole ear welding area, then rotate and open the revolving door 3 on the protective cover 2, and place the lithium-ion battery between the limiting frames 10. The limiting frames 10 are convenient for positioning and limiting the lithium battery. After the lithium battery is placed, place the battery pole ear on the lithium battery, then slide the sliding frame 13 upward on the sleeve 12, so that the fixing bar 15 moves upward, the telescopic spring 14 is stretched, and then the sleeve 12 is slid on the second guide rod 11, so that the fixing bar 15 slides on the sliding frame 13, and the fixing bar 15 moves to the position to be fixed of the lithium-ion battery, and then the telescopic spring 14 rebounds, so that the sliding frame 13 moves downward, so that the fixing bar 15 moves downward and contacts with the pole ear, and then the The tab is pressed and fixed on the lithium-ion battery, thereby playing a role in assisting in pressing and fixing the battery tab during the welding process of the lithium-ion battery tab to avoid injury to the staff. After the tab is fixed, the trackless cylinder 4 is started to make the slider 6 slide on the first guide rod 5 to the welding position of the tab, and then the revolving door 3 is rotated to close, and then the electric push rod 7 is controlled to start, so that the telescopic end of the electric push rod 7 moves downward, driving the welding table 8 to move downward and contact the tab, and the tab is welded to the lithium-ion battery. When the telescopic end of the electric push rod 7 moves downward, the dust suction pipe 9 moves downward. When the lithium battery is welded, the dust suction pipe 9 absorbs the smoke and metal dust generated by welding to prevent the smoke and metal dust from causing harm to the staff.
