Problems solved by technology

[0004] Defects in the above scheme include: first, the above-mentioned fixture can complete the embedding of the lug and the lug slot, and the cell and the cell slot, but the length of the tab and the cell protruding from the notch cannot be accurately controlled and needs to be adjusted manually ; Second, since the tabs and the battery cells are directly placed in the corresponding slots, the welding process is mainly through hand pinching, the clamping force is different, and the relative displacement between the tabs and the battery core is inevitable during the clamping process. Therefore, the relative position of the tab and the battery core cannot be guaranteed to be accurate, and thus the consistency of the performance of the welding product cannot be ensured.

Embodiment 1

[0051] Such as figure 1 As shown, the tab welding positioning tooling in Embodiment 1 includes a battery positioning box 1, and an open tab positioning groove 11 and a battery positioning groove 12 are respectively provided on the opposite box surface of the battery positioning box 1, and the battery positioning The side of the box 1 is provided with a lateral notch for accommodating the protruding part of the tab and the welding part of the battery cell,

[0052] Embodiment 1 also includes a cell gland 2, the edge of the cell gland 2 is provided with a cell rib 3 protruding toward the cell positioning groove 12, and both the cell gland 2 and the cell rib 3 are embedded In the cell positioning groove 12 , the cell rib 3 , the cell gland 2 and the cell positioning groove 12 enclose a cavity to accommodate the cell.

[0053] The cell rib 3 is sandwiched between the lateral notch of the cell positioning groove 12 and the cell gland 2 .

[0054] The cell rib 3 is detachably conn...

Embodiment 2

[0057] Such as Figure 2-4 As shown, embodiment 2 is based on the embodiment, the difference is that the tab welding positioning tool also includes a tab positioning block 4 embedded in the tab positioning groove 11, and the tab positioning block 4 surface opposite to the tab positioning groove 11 It is the tab adsorption surface a, and a vacuum adsorption hole 41 is also provided on the tab adsorption surface a, and the vacuum adsorption hole 41 communicates with the vacuum component (not shown in the figure).

[0058] In order to adapt to the operation that the tab is first adsorbed on the tab adsorption surface, the two sides of the edge of the tab adsorption surface a located at the lateral notch are respectively provided with limiting posts 42, the tab positioning block 4, the limiting post 42 and the tab The lateral notch of the positioning groove 11 surrounds the protruding hole of the welded portion of the tab.

Embodiment 3

[0060] Such as Figure 5 As shown, Embodiment 3 is based on Embodiment 2, the difference is that a limiting member 5 is provided between the cell positioning box 1 and the cell gland 2 .

[0061] The cooperating limiting member 5 includes a boss 51 and a boss slot 52, the boss 51 is protrudingly arranged on the outer edges of both sides of the cell gland 2, and the boss slot 52 is recessed and arranged on both sides of the cell positioning groove 12. On the side wall, the boss 51 and the boss slot 52 are plugged and fitted.

Abstract

The invention discloses a tab welding positioning tool, which comprises a cell positioning box, an open tab positioning slot and a cell positioning slot are respectively arranged on the opposite box surfaces of the cell positioning box, and the side of the cell positioning box is provided with There is a lateral notch for accommodating the tabs and the protruding part of the cell welding part; it also includes a cell gland, the edge of the cell gland is provided with a cell rib that protrudes toward the cell positioning groove, the cell gland and The battery ribs are all embedded in the battery positioning grooves, and the battery ribs, the battery gland and the groove surfaces of the battery positioning grooves are enclosed to form a cavity for accommodating the battery cells. The tab welding positioning tool adds a cell gland, and a cell rib is set on the edge of the cell gland. The cell gland and the cell positioning box clamp the cell to ensure that the position of the cell is fixed during the welding process. ;The edge of the battery cell can ensure the protruding length of the welding part of the battery cell, avoiding the alignment work before the welding operation.

Description

technical field [0001] The invention relates to the technical field of tab electric core welding tooling, in particular to a tab welding positioning tool. Background technique [0002] With the widening of the application field of power lithium batteries, the demand for lithium-ion batteries of various shapes and requirements is increasing. Before the battery is finalized, the process test requires low-cost, simple structure, and accurate positioning welding auxiliary tooling. [0003] The lug welding positioning tool in the prior art is as described in CN207149642U. The clamp carrier is provided with a positive pole lug groove, a negative pole lug groove and a battery cell groove, and the battery core groove and the pole lug groove are respectively located on the opposite surfaces of the fixture carrier. The following content is mentioned in the specific implementation method: ensure that the edge of the diaphragm at the tab end of the battery cell is flush with the side en...
