[0027] Combined with Figure 1 and Figure 2 As shown, this embodiment provides a tab adhesive tape flattening device, including: a rotating assembly, a tooling fixture 20, and an adhesive tape rolling assembly 30, wherein:

[0028] The rotating assembly includes a fixed disk (not shown in the figure) and a rotating disk 10 arranged coaxially. The fixed disk is fixedly arranged above the rotating disk 10, and the rotating disk 10 can rotate around its central axis; a plurality of tooling fixtures 20 are evenly arranged along the circumference of the rotating disk 10. The tooling fixture 20 is used to load the battery. When the rotating disk 10 rotates around its central axis, it drives the tooling fixture 20 to rotate around the central axis of the rotating disk 10; the adhesive tape rolling assembly 30 is arranged on the fixed disk. The adhesive tape rolling assembly 30 can move axially along the rotating disk 10 to the tooling fixture 20. The adhesive tape rolling assembly 30 presses against the battery loaded in the tooling fixture 20 and rolls the tab adhesive tape of the battery to bond the tab adhesive tape to the tab.

[0029] Specifically, the adhesive tape rolling assembly 30 is fixedly arranged on the fixed disk, and the adhesive tape rolling assembly 30 is arranged above the turntable 10. When the turntable 10 rotates around its central axis, the fixed disk does not rotate, and the position of the adhesive tape rolling assembly 30 remains fixed, that is, the adhesive tape rolling assembly 30 does not rotate with the turntable 10, while the tooling fixture 20 rotates with the turntable 10. When the tooling fixture 20 rotates with the turntable 10 to the position of the adhesive tape rolling assembly 30, the adhesive tape rolling assembly 30 can move along the axial direction of the turntable towards the turntable 10 until the adhesive tape rolling assembly 30 presses against the battery loaded on the tooling fixture 20. The adhesive tape rolling assembly 30 rolls the adhesive tape at the root of the battery tab, so that the opened adhesive tape is re-pasted or the unopened adhesive tape is bonded more tightly together, thereby bonding the adhesive tape to the tab to protect the tab and the electrode plate.

[0030] In the tab adhesive tape flattening device provided in this embodiment, by arranging the adhesive tape rolling assembly on the rotating assembly, the turntable can convey the battery cell with the tab folded to the position of the adhesive tape rolling assembly. The adhesive tape rolling assembly rolls the adhesive tape at the root of the battery tab, so that the opened adhesive tape is re-pasted or the unopened adhesive tape is bonded more tightly together, improving the bonding strength of the adhesive tape bonded to the tab, protecting the tab and the electrode plate, avoiding short circuit of the battery cell, and improving the safety, quality stability and qualification rate of the battery cell; in addition, by arranging the adhesive tape rolling assembly on the rotating assembly, the rolling of the adhesive tape is realized during the conveying process of the battery cell, connecting all processes in the production process of the battery cell, which is beneficial to improving the production efficiency of the battery cell.

[0031] As an alternative embodiment, in combination with Figure 3 and Figure 4 As shown, the adhesive tape rolling assembly 30 includes a support seat 31, a first driving member 32, a first mounting seat 33, a second driving member 34 and a roller assembly 35. The first driving member 32, the first mounting seat 33, the second driving member 34 and the roller assembly 35 are all arranged on the support seat 31, and the support seat 31 is fixedly arranged on the fixed disk to realize the fixed arrangement of the adhesive tape rolling assembly 30 on the fixed disk. The second driving member 34 and the roller assembly 35 are both arranged on the first mounting seat 33. The first driving member 32 drives the first mounting seat 33 to move along the axial direction of the turntable 10 to drive the second driving member 34 and the roller assembly 35 to move along the axial direction of the turntable 10, so that the roller assembly 35 can approach and press against the battery loaded on the tooling fixture 20. The second driving member 34 is used to drive the roller assembly 35 to move along the radial direction of the battery, so that the roller assembly 35 rolls the adhesive tape at the root of the battery to bond the adhesive tape to the tab.

[0032] Specifically, in combination with Figures 3 to 5As shown in the figure, two sets of roller components 35 are provided on the first mounting base 33. The two sets of roller components 35 respectively roll press the two tab tapes of the battery. One set of roller components 35 rolls presses the tab tape on the positive tab of the battery, and the other set of roller components 35 rolls presses the tab tape on the negative tab of the battery. A second driving member 34 can be provided to simultaneously drive the two sets of roller components 35 to respectively roll press the two tab tapes of the battery, or two second driving members 34 can be provided to respectively drive the two sets of roller components 35 to roll press the two tab tapes of the battery.

[0033] In this embodiment, the included angle range between the two sets of roller components 35 is 83 degrees to 97 degrees. Thus, after the two tabs of the battery are folded, the included angle range between the two tabs is 83 degrees to 97 degrees. The included angle range between the two sets of roller components 35 is consistent with the included angle range between the two tabs, enabling the two sets of roller components 35 to exactly press against the corresponding tab tapes and roll press the entire tab tape, avoiding rolling pressing only part of the tab tape and still having the risk of short circuit subsequently. Preferably, the included angle between the two tabs is 90 degrees, and the included angle between the two sets of roller components 35 is 90 degrees.

[0034] In this embodiment, four mounting positions are provided on the first mounting base 33. The roller components 35 are installed on two of the mounting positions, and the other two mounting positions are used as spare mounting positions. Thus, when the roller components 35 are damaged, they can be replaced in time, or when the included angle between the two tabs changes, the roller components 35 can be installed on the appropriate mounting positions to facilitate adjusting the included angle between the two sets of roller components 35 according to the included angle between the two tabs.

[0035] Combined with Figure 6 As shown in the figure, each set of roller components 35 includes a second mounting base 351, a third mounting base 352, a connecting shaft 353, and a roller 354. The second mounting base 351 is provided on the first mounting base 33. The connecting shaft 353 connects the second mounting base 351 and the third mounting base 352. The roller 354 is installed on the third mounting base 352. The second driving member 34 drives the second mounting base 351 to move in the radial direction of the battery, and drives the roller 354 to move in the radial direction of the battery through the connecting shaft 353 and the third mounting base 352, so that the roller 354 rolls presses the tab tape at the root of the battery.

[0036] On the basis of the above embodiment, the pressure roller assembly 35 also includes an elastic member 355, which is sleeved on the outside of the connecting shaft 353, and one end of the elastic member 355 abuts against the second mounting seat 351, and the other end of the elastic member 355 abuts against the third mounting seat 352. The elastic member 355 is used to adjust the roller pressure of the pressure roller 354 on the ear tape. Since the size of each battery is slightly different, the distance between the end of the battery and the pressing roller 354 along the axial direction of the turntable 10 is also different, and the preset distance that the pressing roller 354 moves along the axial direction of the turntable 10 is fixed. If the distance between the end of the battery and the pressing roller 354 is less than the preset distance, the battery may be damaged when the pressing roller 354 presses against the battery. If the distance between the end of the battery and the pressing roller 354 is greater than the preset distance, the pressing roller 354 may not contact the end of the battery and cannot smoothly roll the tab tape. Therefore, by setting the elastic member 355, the rolling pressure of the pressing roller 354 rolling the tab tape can be adjusted to play a buffering role, thereby not only avoiding damage to the battery cell, but also ensuring that the pressing roller 354 presses against the tab tape, so that the effect of the pressing roller 354 rolling the tab tape is better. As an optional embodiment, the elastic member 355 can be a compression spring.

[0037] On the basis of the above embodiment, the pressing roller assembly 35 further includes a tab bead 356, which is mounted on the third mounting seat 352 and arranged on the outer side of the pressing roller 354 along the radial direction of the battery. The tab bead 356 is used to press the tab. Therefore, when the pressing roller 354 presses the tab tape, the tab bead 356 can press the tab, preventing the tab from tilting when the pressing roller 354 presses the tab tape, causing defects in subsequent production processes and affecting the production quality of the battery.

[0038] In this embodiment, the tab tape smoothing device further includes a third driving member 40, which is disposed below the turntable 10, and is used to drive the turntable 10 to rotate around its central axis.

[0039] In this embodiment, the first drive member 32, the second drive member 34 and the third drive member 40 can be cylinders or motors, and the first drive member 32, the second drive member 34 and the third drive member 40 can also be matched with mechanical transmission structures such as screw rods, gears, cylinders, chains or synchronous belts to better drive. As an optional embodiment, the first drive member 32 and the second drive member 34 are both cylinders, and the third drive member 40 is a motor, wherein the first drive member 32 can be a lifting cylinder, and the second drive member 34 can be a finger cylinder.

[0040] Combine the following Figures 1 to 6 The working principle of the tab tape smoothing device of this embodiment is described as follows:

[0041] After the tab of the battery is bent and formed, it is loaded onto the tooling fixture 20. The tooling fixture 20 rotates around its central axis along with the turntable 10. The tooling fixture 20 conveys the battery with the bent and formed tab to the adhesive tape roller pressing assembly 30. The first driving member 32 drives the second driving member 34 and the roller pressing assembly 35 to move along the axial direction of the turntable 10 by driving the first mounting seat 33, so that the roller pressing assembly 35 presses against the battery loaded on the tooling fixture 20. The elastic member 355 can adjust the pressing force of the pressing roller 354 pressing against the battery to adjust the roller pressing force of the pressing roller 354 on the tab adhesive tape. Subsequently, the second driving member 34 drives the pressing roller 354 to move along the radial direction of the battery, so that the pressing roller 354 roller presses the tab adhesive tape at the root of the battery, and the tab adhesive tape is bonded to the tab. At the same time, the tab pressing strip 356 presses the tab to prevent the tab from lifting when the pressing roller 354 roller presses the tab adhesive tape.

[0042] Although the present disclosure is disclosed as above, the protection scope of the present disclosure is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present disclosure, and these changes and modifications will all fall within the protection scope of the present utility model.
