[0021] like Figure 1-4As shown, a jig for processing lithium batteries is provided, comprising: a first plate 1, a receiving groove 2 for receiving the lithium battery is provided on the first plate 1, the receiving groove 2 is distributed along the length direction of the first plate 1, the upper and lower parts of the receiving groove 2 are respectively connected to the first plate 1, the upper part of the first plate 1 is provided with a mounting groove 3 for receiving a protective plate, the mounting groove 3 is correspondingly arranged at the position of the receiving groove 2; a second plate 4, the second plate 4 is detachably connected to the first plate 1, the second plate 4 comprises a side plate 5 and a pressing plate 6 hinged to the side plate 5, the side plate 5 cooperates with the receiving groove 2 to fix the lithium battery in the receiving groove 2, and the pressing plate 6 presses the pole ear of the protective plate onto the positive or negative electrode of the lithium battery.

[0022] The fixture for processing lithium batteries is used for processing 18650 lithium batteries. The protection plate with pole ears is welded to the positive and negative electrodes of the 18650 lithium battery. Due to the specifications and position of the protection plate, the fixture is designed for this purpose.

[0023] During use, the accommodating slot 2 is designed to be able to install three 18650 lithium batteries. The three 18650 lithium batteries are welded together in advance. The three 18650 lithium batteries are manually placed in the accommodating slot 2, and one end of the protective plate with the pole ear is welded to the positive or negative electrode of the 18650 lithium battery. After welding, the second plate 4 is manually held, and the side plate 5 and the first plate 1 are used to press the other side of the pole ear of the protective plate. Under the further pressing action of the pressing plate 6, the other side of the pole ear of the protective plate is pressed against the negative or positive electrode of the 18650 lithium battery for welding.

[0024] The above-mentioned fixture has a simple structure. The entire fixture is composed of a first plate 1 and a second plate 4, and the overall processing is more convenient, reducing costs. It is easy to use. The protection plate with the pole ear is manually placed on the mounting groove 3. After welding one end of the protection plate, the pole ear of the protection plate is further pressed onto the other end of the first plate 1 through the second plate 4 for subsequent welding. No professional operation is required, which reduces the work difficulty and is more suitable for wide use.

[0025] Specifically, the side plate 5 is connected to the pressing plate 6 via a hinge. Further, the pressing plate 6 can be rotated relative to the side plate 5, and the pressing plate 6 can press against the tab of the protection plate.

[0026] The pressing plate 6 is provided with welding holes 7 , which are opened corresponding to the positions of the receiving grooves 2 .

[0027] As a preferred embodiment, welding holes 7 are set on the pressure plate 6, and the welding holes 7 are used to weld the pole ears of the protection plate to the positive or negative pole of the lithium battery. This structural design can improve the accuracy of welding and avoid welding errors that may cause damage to the lithium battery.

[0028] Specifically, first magnets 8 are provided on both sides of the side plate 5, and second magnets matching the first magnets 8 are provided on the first plate 1; wherein the first magnets 8 and the second magnets are magnetically attracted, and the side plate 5 is connected to the first plate 1. Third magnets 9 are evenly arranged on the pressure plate 6, and fourth magnets matching the third magnets 9 are provided on the first plate 1; wherein when the third magnets 9 and the fourth magnets are magnetically attracted, the pressure plate 6 is connected to the first plate 1.

[0029] In practice, in order to facilitate the quick connection and quick disassembly of the first plate 1 and the second plate 4, a suitable number of first magnets 8 can be set on the side plate 5 and a corresponding number of second magnets can be set on the first plate 1. When the side plate 5 is close to the first plate 1, the side plate 5 and the first plate 1 are fixed to the lithium battery by magnetic adsorption. The third magnet 9 is set on the first plate 1 and the fourth magnet is set on the pressing plate 6. Under the action of magnetic adsorption, the pressing plate 6 presses the pole ear of the protective plate on the positive or negative electrode of the 18650 lithium battery for subsequent welding operations. After the welding operation, the force of magnetic adsorption is manually overcome to separate the first plate 1 and the second plate 4, and the lithium battery after welding is taken out, and this is repeated.

[0030] The above does not limit the technical scope of the present invention. Any modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
