[0026] like Figure 1-6As shown, a jig for assembling lithium batteries is provided, comprising: a lower plate 1, the lower plate 1 is provided with a first fixing groove 2 for installing and positioning the lithium battery, the lower plate 1 is provided with a first wire groove 3 for accommodating a connecting wire, the first wire groove 3 is communicated with the first fixing groove 2; a side plate 4, the side plates 4 are respectively arranged on both sides of the lower plate 1; an upper plate 5, the upper plate 5 is detachably mounted on the lower plate 1, the upper plate 5 is provided with a second fixing groove 6 for installing and positioning the lithium battery, the upper plate 5 is provided with a second wire groove 7 for accommodating a connecting wire, the second wire groove 7 is communicated with the second fixing groove 6.

[0027] In the processing of 18650 lithium batteries, some small-batch production involves the need to connect two or more 18650 lithium batteries through connecting wires for use. Before processing, two 18650 lithium batteries are adhered by glue, and one side of the two 18650 lithium batteries is welded together with end pieces. When in use, two 18650 lithium batteries are manually installed in the first fixing groove 2 of the lower plate 1 for fixing, and then the second fixing groove 6 of the upper plate 5 is aligned with the two 18650 lithium batteries for limiting, and the connecting wires are manually placed at the positions of the first wire groove 3 and the second wire groove 7 respectively. Since the first wire groove 3 and the second wire groove 7 are respectively connected to the first fixing groove 2 and the second fixing groove 6, the end pieces of the connecting wires are respectively placed at the polarity positions of the 18650 lithium batteries. Finally, the jig is manually placed on the welding machine for welding operation to complete the connection operation of the two 18650 lithium batteries.

[0028] Since the fixture used has a simple structure and is easy to process and prepare, the entire fixture consists of an upper plate 5, a side plate 4 and a lower plate 1, and has a low production cost, which effectively reduces costs; it is easy to use, effectively reduces the difficulty of operation, does not require professional personnel to use it, and saves labor costs.

[0029] Furthermore, the first fixing groove 2 is provided with a first through hole 8 for exposing the polarity of the lithium battery. The second fixing groove 6 is provided with a second through hole 9 for exposing the other polarity of the lithium battery. To facilitate subsequent welding operations, the first through hole 8 and the second through hole 9 are provided to expose the polarity of the lithium battery, so that the end piece of the connecting wire can be easily welded on the lithium battery.

[0030] refer to Figure 3-4 As shown, the side plates 4 are respectively provided with first magnets 10 , the upper plate 5 is provided with second magnets 11 magnetically attracted to the first magnets 10 , and the upper plate 5 is fixed to the lower plate 1 by magnetic attraction.

[0031] In order to quickly connect the upper plate 5 and the lower plate 1, the number of first magnets 10 and second magnets 11 to be installed can be selected according to the implementation situation. In this embodiment, two magnets are installed on the end faces of the side plates 4 respectively, and the assembly and disassembly processes are more convenient and more efficient by magnetic adsorption and fixation.

[0032] Positioning protrusions 12 are respectively provided on the side plates 4 , and positioning holes 13 cooperating with the positioning protrusions 12 are provided on the upper plate 5 .

[0033] By cooperating with the positioning protrusions 12 and the positioning holes 13, positioning can be quickly achieved, and the upper plate 5 and the side plates 4 are fixed by adsorption.

The second wire slot 7 has a third slot portion 16 and a fourth slot portion 17, the width of the third slot portion 16 is greater than the width of the fourth slot portion 17, and the third slot portion 16 is used to limit the lug of the connecting wire.

[0035] Since the connecting wire includes a wire, a terminal and a tab, the tab is used to be welded to the polarity of the 18650 lithium battery. Since there is a width difference between the tab and the wire, by making the width of the first groove portion 14 larger than the width of the second groove portion 15 and the width of the third groove portion 16 larger than the width of the fourth groove portion 17, the tab of the connecting wire can be accurately positioned at the first wire groove 3 and the second wire groove 7 manually.

[0036] 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.
