Mobile phones and laptops use lithium-ion batteries, which are commonly referred to as lithium batteries by people. Batteries generally use materials containing lithium elements as electrodes and are representatives of modern high-performance batteries. During processing, multiple lithium-ion batteries are usually combined, wrapped in a laminated film to form a group, and then welded with nickel sheets, and a lithium-ion battery pack is formed through subsequent processing.
[0003] When welding lithium-ion batteries, workers need to hold a nickel sheet in one hand and place it at the welding position, and operate the welding machine with the other hand. This is not only very inconvenient to operate, but also a slight tremor of the hand holding the nickel sheet during welding will cause the nickel sheet to deviate from the welding point, resulting in a decrease in welding accuracy. In order to prevent the lithium-ion battery from shifting during welding, the lithium-ion battery is usually clamped and fixed. However, when welding the other side after welding one side, the existing clamping and fixing device needs to remove the lithium-ion battery, turn it over, and then fix it again, which is very troublesome.

[0030] In summary, it is possible to assist in positioning the nickel sheet during welding, avoid the situation of nickel sheet deviation caused by wrist shaking when holding the nickel sheet by hand, and thus improve the welding accuracy.
[0031] Please refer to again Figure 1 、 Figure 2 and Figure 4, a lifting block 140 is slidably connected to the lower side of the inner cavity wall of the T-shaped vertical groove plate 110. The lifting block 140 is used to drive the positioning frame 142 to move through the damping rotating shaft 141. A damping rotating shaft 141 is fixedly connected to the left side wall of the lifting block 140. The damping rotating shaft 141 is used to enable the positioning frame 142 to rotate. The left end of the damping rotating shaft 141 extends to the outside of the T-shaped vertical groove plate 110 and is fixedly connected to the positioning frame 142. The positioning frame 142 is used to cooperate with the positioning clamping block 144 to clamp and fix the lithium-ion battery. A servo motor 143 is fixedly connected to the front side of the left side wall of the positioning frame 142 by bolts. The servo motor 143 is used to drive the bidirectional screw 145 to rotate. The left and right sides of the inner side wall of the positioning frame 142 are slidably connected with positioning clamping blocks 144. The positioning clamping blocks 144 are used to clamp and fix the lithium-ion battery. A bidirectional screw 145 is screwed inside the front sides of the two positioning clamping blocks 144. The bidirectional screw 145 is used to drive the two positioning clamping blocks 144 to move towards each other. The right end of the bidirectional screw 145 is connected to the right side inner wall of the positioning frame 142 by a bearing, and the left end of the bidirectional screw 145 is fixedly connected to the output shaft of the servo motor 143. A limiting rod 146 is slidably connected to the rear sides of the two positioning clamping blocks 144. The limiting rod 146 is used to limit the positioning clamping blocks 144.

The second electric telescopic rod 147 is used to drive the lifting block 140 to move, and the top end of the second electric telescopic rod 147 is fixedly connected to the top of the inner cavity wall of the T-shaped vertical groove plate 110. A gasket is provided on the inner side wall of the positioning clamping block 144. The gasket is used to improve the friction between the positioning clamping block 144 and the lithium-ion battery to enhance the fixing effect, and at the same time prevent hard contact between the positioning clamping block 144 and the lithium-ion battery from causing damage to the lithium-ion battery. A placing rubber plate 150 is fixedly connected to the bottom of the base 100 and below the positioning frame 142.

When it is necessary to turn over, start the second electric telescopic rod 147 through an external controller. The second electric telescopic rod 147 thereby drives the positioning frame 142 to move upward through the lifting block 140 in cooperation with the damping rotating shaft 141, and then rotate the positioning frame 142 through the damping rotating shaft 141 to turn over the lithium-ion battery;
[0032] In summary, it is possible to conveniently turn over the lithium-ion battery, so that when welding one side and then welding the other side, there is no need to separately remove the lithium-ion battery for turning over.
[0033] In specific use, when a person skilled in the art uses it, a nickel sheet is placed at the bottom of the hollow block 120. The micro suction pump 121 is started through an external controller. The micro suction pump 121 extracts the air between the nickel sheet and the hollow block 120 through the suction holes 122, thereby fixing the nickel sheet at the bottom of the hollow block 120.

Then, by moving the hollow column 118 to drive the sliding block 114 to slide back and forth on the cross plate 113 to adjust the vertical position of the nickel sheet. After positioning, the first electric telescopic rod 116 is started again through an external controller to make the first electric telescopic rod 116 insert into the adjusted positioning hole 117 to complete the positioning of the nickel sheet. The lithium-ion battery is placed on the placement rubber plate 150. The servo motor 143 is started through an external controller. The output shaft of the servo motor 143 rotates to drive the bidirectional screw 145 to rotate, thereby driving the two positioning clamping blocks 144 to move towards each other in cooperation with the limiting rod 146 to clamp and fix the lithium-ion battery. The hollow block 120 is pulled down by the mounting rod 119 to make the nickel sheet drop to the welding point position for welding by the welding machine body 130. After welding one side, first move the hollow column 118 to the leftmost side. The second electric telescopic rod 147 is started through an external controller. The second electric telescopic rod 147 thus drives the positioning frame 142 to move upward through the lifting block 140 in cooperation with the damping rotating shaft 141, and then rotates the positioning frame 142 through the damping rotating shaft 141 to turn over the lithium-ion battery, and then reset the positioning frame 142 to perform welding on the other side.
