[0022] like Figure 1-6As shown, a combined jig for processing lithium batteries is provided, comprising: a first plate 1, on which a first receiving groove 2 for receiving a lithium battery is provided, the number of the first receiving grooves 2 is more than one, the first receiving grooves 2 are distributed in a linear array on the first plate 1, and the first receiving grooves 2 are respectively provided with mounting grooves 3 for receiving a lithium battery protection plate; a second plate 4, the second plate 4 is detachably connected to the first plate 1, and at least one end surface of the second plate 4 is provided with a second receiving groove 5 for receiving a lithium battery, the second receiving groove 5 is arranged corresponding to the first receiving groove 2, and the second receiving groove 5 and the first receiving groove 2 form a fixation for the lithium battery; a third plate 6, the third plate 6 is provided with a recessed area 7 for receiving the first plate 1, and the upper and lower sides of the third plate 6 are provided with positioning pieces 8 extending toward the first receiving groove 2, and the positioning pieces 8 are used to press the pole ears of the protection plate onto the positive and negative electrodes of the lithium battery.

[0023] In view of the technical problems recorded in the background technology, a combination jig for processing lithium batteries is provided, which is mainly used for welding a protection plate with pole ears to the positive and negative electrodes of a lithium battery. When in use, the protection plate with pole ears is manually embedded in the mounting groove 3, and the pole ears at both ends of the protection plate extend outside the first plate 1, and then the lithium battery is placed in the first receiving groove 2. The first receiving groove 2 is designed according to the contour of the lithium battery. Since the processing object is a 18650 lithium battery, its structure is cylindrical, so the first receiving groove 2 is an arc groove structure. The second receiving groove 5 of the second plate 4 is manually matched with the first receiving groove 2, and the first receiving groove 2 and the second receiving groove 5 fix the lithium battery, and then the recessed area 7 of the third plate 6 is matched with the first plate 1, and the positioning piece 8 on the third plate 6 presses the pole ears of the protection plate on the positive and negative electrodes of the lithium battery, and then, it is manually placed on the welding equipment for welding operation.

[0024] By adopting the above technical solution, the entire fixture is composed of a first plate 1, a second plate 4 and a third plate 6. It has a simple structure and low manufacturing cost. It can fix the protection plate and the lithium battery, which is convenient for subsequent welding operations. The operation method is convenient. The protection plate is manually embedded in the installation groove 3, and the lithium battery is installed and fixed between the first receiving groove 2 and the second receiving groove 5. The positioning piece 8 of the third plate 6 is used to press the pole ears of the protection plate onto the positive and negative poles of the lithium battery. No professional personnel are required, and it is more suitable for wide use.

[0025] Specifically, a wire groove 9 for accommodating the connecting wire is provided on the first accommodating groove 2 , a first end of the wire groove 9 extends to the mounting groove 3 , and a second end of the wire groove 9 extends to an edge of the first plate 1 .

[0026] Since there are connection terminals on the protection board, by providing a wire groove 9, after the protection board is embedded in the installation groove 3, the connection terminals of the protection board are led out through the wire groove 9, which will not cause any influence in the subsequent welding.

[0027] First magnets 10 are respectively disposed on both sides of the first plate 1 , and second magnets 11 cooperating with the first magnets 10 are disposed on both sides of the second plate 4 . The first plate 1 and the second plate 4 are fixed or disassembled by magnetic adsorption.

[0028] In implementation, in order to facilitate the quick connection and quick disassembly of the first plate 1 and the second plate 4, the first plate 1 and the second plate 4 are connected by magnetic adsorption. The number and installation position of the first magnets 10 can be selected and installed according to actual conditions. The second magnet 11 is set corresponding to the first magnet 10. When in use, the first plate 1 and the second plate 4 are manually brought close to each other. Under the action of magnetic adsorption, the first plate 1 and the second plate 4 can be quickly connected or disassembled.

[0029] Positioning bosses 12 are respectively provided on both sides of the first plate 1 , and positioning holes 13 matched with the positioning bosses 12 are respectively provided on both sides of the second plate 4 .
