[0027] Example 1

[0028] This embodiment provides a tab gluing device, comprising a first structure for placing and positioning battery cells and a second structure for positioning tab protection tape when gluing tabs, wherein the first structure and the second structure are vertically stacked up and down.

[0029] The ultrasonic welding post-tab gluing device provided in the present application is mainly used for manual gluing. By cooperating with the first structure and the second structure, the position of the protective tape is clearly limited, which reduces the influence of human uncontrollable factors. It can effectively reduce the proportion of defects such as battery cell short circuit and laser welding explosion points caused by poor gluing, and improve the gluing yield.

[0030] Example 2

[0031] In this embodiment, one side of the first structure and the second structure are connected by a hinge 6, and the other side can be opened and closed.

[0032] With this structure, when adjusting the second structure, the first structure can be opened and rotated around the hinge, and after adjustment, the first structure can be closed. The hinge 6 can be a hinge or other hinges in the prior art.

[0033] Example 3

[0034] This embodiment provides a specific structure of a first structure, which includes a transparent upper plate body 1, a first positioning block 4 fixedly connected to one side of the upper end of the upper plate body 1 along the longitudinal direction, and a second positioning block 5 connected to the upper end of the upper plate body 1 along the transverse direction and arranged perpendicular to the first positioning block 4, and capable of adjusting its position along the longitudinal direction.

[0035] It should be noted that the first structure is used to carry the battery cell after ultrasonic welding and fix the position of the battery cell. The first positioning block 4 and the second positioning block 5 are combined into a right angle, which can fix the position of the battery cell and is used to fix the battery cell to be glued after ultrasonic welding.

[0036] Among them, a horizontal upper plate body center line 3 is set in the middle position of the upper end of the upper plate body 1, and the upper end of the upper plate body 1 is divided into two parts by the upper plate body center line 3, one part of which is provided with two long mounting holes 7 arranged parallel in the longitudinal direction, and the screw passes through the second positioning block 5 and is connected to the long mounting hole 7.

[0037] When the second positioning block needs to be adjusted, the screw is loosened, and then, after adjusting the position of the second positioning block, the screw is tightened. By adjusting the distance between the second positioning block 5 and the middle line 3 of the upper plate, different types of battery cells can be compatible.

[0038] Example 4

[0039] This embodiment provides a specific structure of the second structure, which includes a lower plate body 2, a first positioning mechanism and a second positioning mechanism arranged at the upper end of the lower plate body 2 and arranged in a symmetrical structure, the first positioning mechanism including a third positioning block 8 arranged in the transverse direction, connected to the lower plate body 2 and capable of adjusting the longitudinal position, and four fourth positioning blocks 11 arranged in the longitudinal direction, connected to the third positioning block 8 and capable of adjusting the transverse position.

[0040] It should be noted that the second structure is used to refer to the position where the tape is attached to the tab.

[0041] Wherein, the lower plate body 2 is a U-shaped plate, and the first positioning mechanism and the second positioning mechanism are arranged in the U-shaped groove of the U-shaped plate.

[0042] The lower plate 2 is provided with two parallel rows of longitudinal connection holes 10, each row comprising a plurality of evenly spaced holes. Screws pass through the third positioning block 8 to connect the third positioning block 8 to the lower plate 2. When the third positioning block needs to be adjusted, the screws are loosened, and then, after adjusting the position of the second positioning block, the screws are screwed into the corresponding connection holes.

[0043] The third positioning block 8 is provided with a horizontal row of connecting holes 9, each row including a plurality of evenly spaced holes. Screws pass through the fourth positioning block 11 to connect the fourth positioning block 11 to the third positioning block 8. When the fourth positioning block needs to be adjusted, the screws are loosened, and then, after adjusting the position of the fourth positioning block, the screws are screwed into the corresponding connecting holes.

[0044] It should be noted that the third and fourth positioning blocks are positioned perpendicularly, and the block 4 can be moved via through-holes and threaded holes. By shifting the relative position of the fourth positioning blocks, a reference position is provided for applying the protective tape. Each pair of fourth positioning blocks secures a single adhesive application point, corresponding to the four protective tape application points on a single side of the cell. Furthermore, the third positioning block is positioned perpendicular to the lower plate, and by moving the third positioning block, the height of the protective tape extending beyond the tab weld mark can be adjusted.

[0045] Example 5

[0046] The lower plate 2, the third positioning block 8, and the fourth positioning block 11 provided in this embodiment have different colors.

[0047] It should be noted that, in the tab glue tooling, in order to make the limit reference more obvious, the actual color of block 6 can be differentiated from that of block 5 and block 4.

[0048] It should be noted that the process of gluing is as follows: Figure 3 shown.

[0049] It should be noted that Figure 4 The second pasting position 14, the third pasting position 15, the fourth pasting position 16, and the fifth pasting position 17 can be fixed by the fourth positioning block 11. The right angle limit 12 is fixed by Figure 1 The positioning blocks 4 and 5 shown are perpendicularly intersected and combined to form a right-angle limit.

[0050] Figure 4 The first paste position 13 in the first paste position 13, through Figure 2 The third positioning block 8 and the fourth positioning block 11 work together to achieve fixation.

[0051] After the adjustment of the second structure is completed, close the first structure and the second structure, place the battery cells, and combine the transparent plate characteristics of the upper plate. Figure 4 Just indicate to paste it.

[0054] It should be noted that when placing Figure 1 Centerline and Figure 4 The center lines of the pole groups coincide, Figure 1 The distance from the right side of the second positioning block 5 to the center line 3 is Figure 4 The distance from the edge of the electrode group sample to the center of the electrode group remains consistent.

[0055] at the same time, Figure 4 The 12 right angles marked in the figure should pass through Figure 1 The middle positioning block 4 and the positioning block 5 intersect to produce right-angle contact positioning. Figure 1 The middle positioning block 4 and the center line 3 are the positioning reference datums.
