[0024] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0025] An embodiment of the present application provides a gluing module, which can solve the technical problem in the related art that when gluing the battery cell, the tape is first adhered to the side of the battery cell, and then the tape is pressed toward the upper and lower surfaces of the battery cell using the gluing module, which may cause the tape near the right-angled edge of the side of the battery cell to not be well adhered to the battery cell, thereby affecting the quality of the battery cell.

[0026] See also Figure 1 As shown, a glue sticking module provided by an embodiment of the present application may include: a battery cell pushing component 1, the battery cell pushing component 1 is used to push the side of the battery cell; at least two groups of tape pressing components 2, at least two groups of tape pressing components 2 are located on opposite sides of the battery cell pushing component 1, each group of tape pressing components 2 includes a tape adsorption part 21 and a tape pushing component 22 connected to the tape adsorption part 21, the tape pushing component 22 is located between the tape adsorption part 21 and the tape pressing component 22. The battery cell pushing assembly 1 is provided with a driving assembly 3, wherein the driving assembly 3 is connected to the tape pushing assembly 22, and the driving assembly 3 is configured to drive the tape pushing assembly 22 along the pushing direction of the battery cell pushing assembly 1. The tape adsorption parts 21 on both sides of the battery cell pushing assembly 1 can jointly adsorb a tape, and the tape can be cut in the previous process. The tape is adhered to the side surface and the upper and lower surfaces of the battery cell under the action of the battery cell pushing assembly 1 and the tape pushing assembly 22.

[0027] The embodiment of the present application absorbs the tape through the tape adsorption member 21. When the tape adsorption members 21 located on both sides of the battery cell pushing component 1 jointly adsorb the same piece of tape, the battery cell pushing component 1 can be located in the middle of the tape. It should be understood that the middle does not only refer to the middle of the tape, but can also include any position other than the two ends of the tape. When the side of the battery cell gradually approaches the battery cell pushing component 1 and is subsequently pushed by the battery cell pushing component 1, the side of the battery cell is also in contact with the tape near the battery cell pushing component 1. The tape pushing components 22 located on both sides of the battery cell pushing component 1 can be driven by the driving component 3 to adsorb the tape. The tape absorbed by the component 21 is gradually pushed from the side of the battery cell to the middle of the battery cell, and the tape is adhered to the two side surfaces of the battery cell during the pushing process. Preferably, when the side surface of the battery cell and the battery cell pushing component 1 are in contact with each other, the end of the tape pushing component 22 close to the battery cell can have a certain distance from the battery cell along the pushing direction of the battery cell pushing component 1, so that the tape pushing component 22 can better adhere the tape to the right-angled side of the battery cell, which solves the technical problem that the gluing method used in the related art may cause the tape near the right-angled side of the battery cell to not be well adhered to the battery cell, thereby affecting the quality of the battery cell.

[0028] In some optional embodiments, each group of the tape pressing assembly 2 also includes a push rod 23, the push rod 23 is connected to the driving assembly 3, and the end of the push rod 23 away from the driving assembly 3 is connected to the tape adsorption component 21; the tape pushing assembly 22 is connected to the push rod 23, and the tape pushing assembly 22 is located between the push rod 23 and the battery cell pushing assembly 1. The tape pushing assembly 22 and the push rod 23 can be arranged up and down, and a pushing compression member 24 and a limiting assembly 25 are connected between the push rod 23 and the tape pushing assembly 22. The pushing compression member 24 is located between the push rod 23 and the tape pushing assembly 22, which can make the push rod 23 and the tape pushing assembly 22 have a certain thrust, that is, even if the push rod 23 and the tape pushing assembly 22 respectively have a force to move in a direction away from each other, under the action of the limiting assembly 25, the distance between the push rod 23 and the tape pushing assembly 22 is limited to a certain extent.

[0029] In the embodiment of the present application, the push-compression member 24 is configured as a spring compressed to a certain height. In some other embodiments, the push-compression member 24 can also be configured as a structure with other elasticity. Preferably, in order to reduce the influence of the battery cell pushing assembly 1 on the tape pushing assembly 22, the width of the battery cell pushing assembly 1 along the height direction of the battery cell can be selected to be slightly smaller than the thickness of the battery cell. Then, during the process of gluing, before contacting the battery cell, the distance between the tape pushing assembly 22 and the battery cell pushing assembly 1 may be smaller under the action of the pushing compression member 24. When the tape pushing assembly 22 just contacts the battery cell, the tape pushing assembly 22 may first contact a right-angled edge somewhere on the side of the battery cell close to the upper and lower surfaces. Thereafter, the tape pushing assembly 22 continues to move. Since the battery cell has a certain thickness, the tape pushing assembly 22 is pushed by the battery cell to move toward the direction close to the push rod 23. At this time, the tape pushing assembly 22 will form a certain thrust on the upper or lower surface of the battery cell under the action of the pushing compression member 24. Under the action of this thrust, the tape can be more tightly attached to the upper and lower surfaces of the battery cell.

[0030] Preferably, the tape pushing assembly 22 may include a rod and a roller connected to the rod, and the roller is arranged on the side of the rod close to the battery cell. In the process of the tape pushing assembly 22 pushing the tape, the tape is attached to the battery cell through the roller, which can further protect the battery cell and reduce the possibility of damage.

[0031] In some optional embodiments, the tape pushing assembly 22 is fixed with a guide block 26, and the push rod 23 is installed in the guide groove of the guide block 26. Preferably, the top surface of the guide block 26 can have an opening to facilitate the push rod 23 to be directly installed into the guide groove from the opening during installation. Under the action of the guide block 26, when the tape pushing assembly 22 moves in a direction away from or close to the push rod 23 under the action of the push compression member 24 and the battery cell, the tape pushing assembly 22 can always remain in a state of vertical movement, effectively reducing the possibility of its movement direction being offset. In some other embodiments, the top surface of the guide block 26 can also be set to be closed.

[0032] In some optional embodiments, the driving assembly 3 may include: a driving frame 31, which is connected to the push rod 23; a first driving cylinder, which is installed on the driving frame 31, and the first driving cylinder is configured to drive the driving frame 31 to move along the pushing direction of the battery cell pushing assembly 1, that is, the driving frame 31 can be driven to move along the pushing direction of the battery cell pushing assembly 1 under the action of the first driving cylinder. Of course, the driving frame 31 can also be driven to move in the direction opposite to the pushing direction of the battery cell pushing assembly 1 under the action of the first driving cylinder, and the push rod 23 also moves accordingly under the drive of the driving frame 31. Since the push rod 23 is connected to the tape pushing assembly 22, during the movement of the driving frame 31, the tape adsorption component 21 and the tape pushing assembly 22 also move synchronously.

[0033] In some optional embodiments, the battery cell pushing assembly 1 may include: a driving mechanism 11, the driving mechanism 11 is installed on the driving frame 31; a pushing member 12, the pushing member 12 is connected to the driving mechanism 11, and the pushing member 12 is passed through a side plate of the driving frame 31, and a pushing block 13 is installed at the end of the pushing member 12 away from the driving mechanism 11. The pushing block 13 can directly contact the side of the battery cell. In order to effectively reduce the damage of the pushing block 13 to the battery cell, the pushing block 13 is made of non-metallic material. The pushing member 12 can reciprocate along the pushing direction of the battery cell pushing assembly 1 under the action of the driving mechanism 11. When the pushing member 12 moves, the driving frame 31 can remain stationary. By driving the pushing member 12 by the driving mechanism 11, the pushing force of the pushing block 13 can be adjusted by the driving mechanism 11 when pushing the side of the battery cell, thereby enhancing the fit between the pushing block 13 and the battery cell and avoiding damage to the battery cell.

[0034] See also Figure 2 As shown, in some optional embodiments, the driving mechanism 11 may include: a linear rail 111, which is installed on the driving frame 31, and the linear rail 111 extends along the extension direction of the pushing member 12; a second driving cylinder 112, the second driving cylinder 112 is connected to a sliding rod 113, the sliding rod 113 is slidably installed on the linear rail 111, and one end of the sliding rod 113 is connected to the pushing member 12. In the embodiment of the present application, through the cooperation of the linear rail 111 and the sliding rod 113, the second driving cylinder 112 can maintain a certain moving direction during the process of driving the pushing member 12 to move, thereby reducing the possibility of offset.

[0035] In some optional embodiments, an adjustment member 14 is sandwiched between the sliding rod 113 and the pushing member 12, and the adjusting member 14 has a mounting groove, the pushing member 12 is passed through the mounting groove, and the pushing member 12 and the two side walls of the mounting groove are passed through a first rotating shaft; both side walls of the mounting groove have an annular groove, and the annular groove is passed through a fixing bolt. In the embodiment of the present application, the pushing member 12 can be rotatably installed on the adjusting member 14, and the axis of the first rotating shaft can be perpendicular to the extension direction of the pushing member 12, so that the pushing member 12 can adjust the angle under the action of the first rotating shaft. When the angle between the push block 13 and the battery cell is offset to a certain extent, the offset can be adjusted by adjusting the angle of the pushing member 12. After the offset adjustment is completed, a fixing bolt is passed through the annular groove to fix the positions of the pushing member 12 and the adjusting member 14, so that the glue-sticking module can adapt to various conditions.

[0036] Preferably, the second driving cylinder 112 is installed on the driving frame 31 through a mounting sleeve 15 fixed to the driving frame 31, and the second driving cylinder 112 is passed through a side wall of the driving frame 31; the driving mechanism 11 also includes a connecting plate 16, and the connecting plate 16 is fixed to the second driving cylinder 112 and one end of the sliding rod 113 away from the driving frame 31, that is, the second driving cylinder 112 indirectly drives the sliding rod 113 to move through the connecting plate 16. This method can make the sliding rod 113 more stable during movement.

[0037] See also Figure 3 As shown, in some optional embodiments, the driving assembly 3 further includes an angle adjustment member 32, the angle adjustment member 32 is fixed to the driving frame 31, and the angle adjustment member 32 is provided with a receiving groove, the push rod 23 is received in the receiving groove, and the push rod 23 and the angle adjustment member 32 are connected by a second rotating shaft 321; a side wall of the angle adjustment member 32 is further provided with a plurality of first bolt holes 322, the push rod 23 is provided with a plurality of second bolt holes corresponding to the first bolt holes 322, and the inner diameter of the first bolt hole 322 is greater than The inner diameter of the second bolt hole, the first bolt hole 322 and the second bolt hole are jointly penetrated by a fixing part, which can be a bolt. In the embodiment of the present application, by setting the angle adjustment part 32, the angle of the push rod 23 relative to the driving frame 31 can be adjusted, and the glue-applying module can be further made to have stronger environmental adaptability. It should be understood that the inner diameter of the first bolt hole 322 is larger than the inner diameter of the bolt hole, but it should also be ensured that the inner diameter of the first bolt hole 322 is smaller than the nut diameter of the bolt, so that the angle adjustment part 32 and the push rod 23 can be effectively fixed when the bolt is tightened.

[0038] Preferably, each of the tape adsorbents 21 is equipped with a vacuum joint, that is, the tape adsorbent 21 adsorbs the tape by vacuuming, and all the tape adsorbents 21 can be connected to a vacuum pump so that multiple tape adsorbents 21 can be absorbed or put down synchronously.
