Description

Technical Field

[0001] The present application relates to the technical field of electrochemical devices, and in particular to a battery cell gluing device and a method for manufacturing the battery cell gluing device. Background Art

[0002] Due to their high energy density and light weight, lithium batteries are widely used in various technologies, including portable electronic devices and electric vehicles. During lithium battery production, the tabs of the cells must be welded. After welding, the tabs must be glued to secure and insulate the tabs. However, existing glue-applying equipment suffers from low glue-applying efficiency, large size, and high energy consumption. Summary of the Invention

[0003] The purpose of the embodiments of the present application is to provide a battery cell gluing device and a method for manufacturing the battery cell gluing device, so as to improve the gluing efficiency of the battery cell gluing device, reduce the volume of the battery cell gluing device and reduce the volume of the gluing device. The specific technical solution is as follows:

[0004] A first aspect of an embodiment of the present application provides a battery cell gluing device, the battery cell gluing device comprising:

[0005] Tooling board, used to carry battery cells;

[0006] The adhesive tape clamping and pulling mechanism is located above the tooling plate and is used to clamp the adhesive tape and drive the adhesive tape to move horizontally in a direction close to the battery cell;

[0007] The rubber cutting mechanism is located in front of the tooling plate along the conveying direction of the tape and is used to cut the tape into tape segments;

[0008] The gluing mechanism is located above the tooling plate and is used to press the tape segment onto the area to be glued;

[0009] The driving mechanism includes a motor and a transmission assembly. The motor is connected to the clamping and pulling mechanism, the glue cutting mechanism and the glue sticking mechanism through the transmission assembly to synchronously drive the clamping and pulling mechanism, the glue cutting mechanism and the glue sticking mechanism.

[0010] According to the battery cell gluing equipment of the embodiment of the present application, driven by the clamping and pulling mechanism, the tape passes through the glue cutting mechanism and the glue sticking structure in sequence, and is pressed onto the battery cell under the action of the glue sticking mechanism. The conveying path of the tape is short, and the various mechanisms cooperate closely, which increases the glue sticking efficiency of the battery cell gluing equipment. In addition, the driving mechanism uses the same motor to synchronously drive multiple mechanisms, which reduces the volume and energy consumption of the battery cell gluing equipment on the basis of further improving the working efficiency of the battery cell gluing equipment.

[0011] In some embodiments, the battery cell gluing equipment further includes a glue preparation mechanism, which is located on a side of the glue cutting mechanism away from the tooling board. The glue preparation mechanism is used to carry the tape and transport the tape toward the tooling board.

[0012] In some embodiments, the transmission assembly includes a cam drive group.

[0013] In some embodiments, a cam drive assembly includes a cam, a roller, a first connecting plate, and a connecting rod. The roller is disposed on the first connecting plate, and the cam abuts the roller. One end of the connecting rod is connected to the first connecting plate, and the other end of the connecting rod is connected to a mechanism to be driven. The cam drives the connecting rod to move vertically via the roller and the first connecting plate. The mechanism to be driven is at least one of a rubber clamping and pulling mechanism, a rubber cutting mechanism, and a rubber applying mechanism. Thus, multiple cams can synchronously drive the mechanism to be driven, and the multiple cams drive the connecting rods connected thereto to perform reciprocating linear motion. The multiple cams move synchronously without interfering with each other, resulting in a high stability of the cam drive assembly.

[0014] In some embodiments, the connecting rod includes a first section and a second section, the first section and the second section being threadedly connected, and the depth of the threaded connection between the first section and the second section is adjustable. Thus, the overall length of the connecting rod can be adjusted by adjusting the threaded depth of the first section and the second section. Therefore, the initial position and the position at which the connecting rod moves can be changed without replacing the connecting rod, thereby enabling precise adjustment of the initial position and the position at which the connecting rod moves.

[0015] In some embodiments, the cam drive group includes a first rod end bearing and a second rod end bearing, one end of the connecting rod is connected to the first connecting plate through the first rod end bearing, and the other end of the connecting rod is connected to the driven mechanism through the second rod end bearing.

[0016] In some embodiments, the first and second rod-end bearings are threadedly connected to the connecting rod, and the depth of the threaded connection between the connecting rod and the first and second rod-end bearings is adjustable. Thus, the distance between the first and second rod-end bearings can be adjusted, thereby enabling the initial and final positions of the connecting rod to be changed without replacing the connecting rod, thereby enabling precise adjustment of the initial and final positions of the connecting rod.

[0017] In some embodiments, the drive mechanism further includes an encoder for controlling the rotation angle of the cams. The encoder is used to monitor the rotation angle of the output shaft, thereby determining the rotation angle of multiple cams disposed on the output shaft at a specific moment or within a predetermined time period. This improves the positional accuracy and consistency of each cam during operation and reduces the possibility of cam-to-cam collisions caused by deviations in the position of one or more cams.

[0018] In some embodiments, the battery cell taping apparatus further includes a debonding mechanism located between the adhesive preparation mechanism and the adhesive cutting mechanism. The debonding mechanism is configured to apply downward pressure to the adhesive tape to release at least a portion of the adhesive tape from the adhesive preparation mechanism. The debonding mechanism is configured to apply downward pressure to the adhesive tape to cause a portion of the adhesive tape to be peeled off the tape roll, thereby debonding the tape roll and conveying the debonded tape toward the battery cell to be taped.

[0019] In some embodiments, the battery cell taping equipment further includes a mounting plate, and the debonding mechanism includes a first roller, a second roller, and a third roller disposed on the mounting plate. The second roller is positioned between the first and third rollers and is movable vertically, with the tape sequentially passing through the highest point of the first roller, the lowest point of the second roller, and the highest point of the third roller. The second roller drives the tape vertically, applying downward pressure to the tape to debond it. The first, second, and third rollers collectively support and guide the tape.

[0020] In some embodiments, the debonding mechanism further includes a first track disposed on the mounting plate and extending in a vertical direction, and the second roller is slidably connected to the first track;

[0021] The motor is used to synchronously drive the glue clamping and pulling mechanism, the glue cutting mechanism, the glue applying mechanism and the second roller.

[0022] In some embodiments, the core laminating apparatus further includes a first guide roller and a second guide roller, located between the adhesive stripping mechanism and the adhesive cutting mechanism. The adhesive tape sequentially passes over the lowest point of the first guide roller and the highest point of the second guide roller. The first guide roller and the second guide roller are used to support and guide the adhesive tape, keeping it taut and reducing the likelihood of the tape sticking and wrinkling.

[0023] In some embodiments, the glue preparation mechanism includes a tape installation roller and a brake connected to the tape installation roller. The tape is installed on the tape installation roller. The brake is used to control the rotation state of the tape installation roller and limit the amount of tape unsealing, thereby reducing the probability of excessive tape unsealing due to rotational inertia and other reasons during the tape conveying process, resulting in the probability of the tape sticking and wrinkling.

[0024] In some embodiments, the battery cell gluing device further includes a glue pressing mechanism, which is located on a side of the glue cutting mechanism away from the tooling plate, and is used to fix the tape.

[0025] In some embodiments, the adhesive pressing mechanism includes a support block and an adhesive pressing slider located above the support block, the adhesive pressing slider can move in a vertical direction, and the adhesive tape is located between the adhesive pressing slider and the support block;

[0026] The motor is also connected to the glue pressing slider through a driving component to synchronously drive the glue clamping and pulling mechanism, the glue cutting mechanism, the glue applying mechanism and the glue pressing slider.

[0027] In some embodiments, the gluing mechanism includes a second guide rail extending in a vertical direction and a pressure block structure slidably connected to the second guide rail. The motor is connected to the pressure block structure through a transmission assembly to drive the pressure block structure to slide relative to the second guide rail, thereby driving the tape under the pressure block structure to move downward to adhere to the battery cell.

[0028] In some embodiments, the pressure block structure includes a first pressure block, at least one first connecting rod, at least one second connecting rod, and a second pressure block. The first pressure block is connected to the transmission assembly, and the first pressure block is connected to the second pressure block through at least one first connecting rod and at least one second connecting rod. At least one first connecting rod or at least one second connecting rod includes an elastic member. The first pressure block and the second pressure block are connected through the first connecting rod or the second connecting rod. Since the first connecting rod or the second connecting rod has an elastic member, when the pressure block structure as a whole moves downward and contacts the surface of the battery cell, the elastic member acts as a buffer for the pressure block structure while providing space for the pressure block structure to continue to move downward, so that part of the pressure block structure continues to move downward until it contacts the battery cell tab, so that the tape can be attached to the large surface of the battery cell and the battery cell tab.

[0029] In some embodiments, the drive mechanism further includes a cylinder assembly; the adhesive clamping and pulling mechanism includes a first clamping block and a second clamping block, and the cylinder assembly is connected to the first clamping block and / or the second clamping block to drive the first clamping block and / or the second clamping block to move in a vertical direction. In the vertical direction, the adhesive tape is positioned between the first clamping block and the second clamping block, and the cylinder assembly controls the movement of the first clamping block and / or the second clamping block to control the first clamping block and the second clamping block to jointly clamp the adhesive tape.

[0030] A second aspect of the embodiments of the present application provides a method for manufacturing a battery cell gluing device, the method comprising:

[0031] Provide tooling board, which is used to carry battery cells;

[0032] A clamping and pulling mechanism is provided. The clamping and pulling mechanism is located above the tooling plate. The clamping and pulling mechanism is used to clamp the tape and drive the tape to move horizontally and toward the battery cell.

The motor is connected to the clamping and pulling mechanism, the glue cutting mechanism and the glue sticking mechanism through the transmission assembly to synchronously drive the clamping and pulling mechanism, the glue cutting mechanism and the glue sticking mechanism.

DETAILED DESCRIPTION

[0045] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field based on this application are within the scope of protection of this application.

[0046] In the description of this application, it should be noted that, unless otherwise specified, "multiple" means more than two; the terms "upper", "lower", "left", "right", "inside", "outside", etc., indicating directions or positional relationships, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting this application. In addition, the terms "first", "second", "third", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. "Vertical" is not strictly perpendicular, but is within the allowable error range. "Parallel" is not strictly parallel, but is within the allowable error range.

[0047] The directional words appearing in the following description are all directions shown in the figures, and do not limit the specific structure of this application. In the description of this application, it should also be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0048] The term "and / or" in this application simply describes an association between related objects, indicating that three possible relationships exist. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in this application generally indicates that the related objects are in an "or" relationship.

[0049] In the embodiments of this application, the same reference numerals represent the same components, and for the sake of brevity, detailed descriptions of the same components in different embodiments are omitted. It should be understood that the thickness, length, width, and other dimensions of the various components in the embodiments of this application, as well as the overall thickness, length, width, and other dimensions of the integrated device shown in the drawings are merely illustrative and should not constitute any limitation on this application.

[0050] The term "plurality" used in this application refers to two or more (including two).

[0051] The battery cells mentioned in the embodiments of the present application may also be referred to as battery cells. Battery cells are used to form batteries. A battery may include one or more battery cells to provide higher voltage and capacity. A battery generally includes a casing for encapsulating one or more battery cells. The casing can prevent liquids or other foreign matter from affecting the charging or discharging of the battery cells. In the present application, battery cells may include aluminum shell batteries, soft-pack batteries, cylindrical batteries, etc., which are not limited in the embodiments of the present application. Battery cells may be cylindrical, flat, rectangular, or in other shapes, which are not limited in the embodiments of the present application.

[0052] Multiple batteries can be connected in series and / or in parallel via terminals for use in various applications. In some high-power applications, such as electric vehicles, battery applications include three levels: cells, battery modules, and battery packs. A battery module is a system consisting of a number of cells electrically connected together and housed in a frame to protect the cells from external shock, heat, and vibration. A battery pack is the final battery system installed in an electric vehicle. A battery pack typically includes a casing that encloses one or more cells. The casing prevents liquids or other foreign matter from affecting the charging or discharging of the cells. The casing typically consists of a cover and a shell. Currently, most battery packs are made by assembling various control and protection systems, such as a battery management system (BMS) and thermal management components, onto one or more battery modules. With technological advancements, the battery module level can be eliminated, allowing battery packs to be formed directly from the cells. This improvement increases the gravimetric and volumetric energy densities of the battery system while significantly reducing the number of components. Batteries referred to in this application include either battery modules or battery packs.

[0053] The technical solutions described in the embodiments of the present application are applicable to various battery-using devices, such as mobile phones, portable devices, laptop computers, electric vehicles, electric toys, electric tools, electric vehicles, ships and spacecraft, etc. For example, spacecraft include airplanes, rockets, space shuttles and spacecraft, etc.

[0054] In the related art, a battery cell includes an electrode assembly, a battery cell shell, and an electrode terminal connected to the electrode assembly and led out from the battery cell shell, wherein the electrode terminal may also be referred to as a tab. In the production process of the battery, the positive and negative electrodes need to be spaced apart to form a battery cell. After the battery cell is formed, the tabs of the battery cell need to be welded, and after the tabs are welded, the welded parts of the tabs need to be glued to fix and insulate the tabs of the battery cell. The battery cell gluing equipment needs to complete processes such as glue pulling, glue pressing, and glue cutting. Therefore, the battery cell gluing equipment mostly includes multiple mechanisms. However, the coordination between the various mechanisms in the current battery cell gluing equipment is not tight, the gluing efficiency is low, and the multiple mechanisms need to be driven by different driving devices, which makes the battery cell gluing equipment larger in size and has higher energy consumption.

[0055] Based on the various problems of the above-mentioned battery cell gluing equipment, the inventor has developed a new type of battery cell gluing equipment, namely the battery cell gluing equipment of the present application. By adopting the same motor to synchronously drive multiple mechanisms, the volume and energy consumption of the battery cell gluing equipment are reduced on the basis of improving the working efficiency of the battery cell gluing equipment.

[0056] like Figures 1 to 5As shown, the battery cell gluing equipment provided by the embodiment of the first aspect of the present application includes a tooling plate 1, a clamping and pulling glue mechanism 3, a glue cutting mechanism 4, a glue sticking mechanism 5 and a driving mechanism 6. Among them, the tooling plate 1 is used to carry the battery cell 11. The clamping and pulling glue mechanism 3 is located above the tooling plate 1, and the clamping and pulling glue mechanism 3 is used to clamp the tape 21 and drive the tape 21 to move horizontally and toward the battery cell 11. Along the conveying direction of the tape 21, the glue cutting mechanism 4 is located in front of the tooling plate 1, and the glue cutting mechanism 4 is used to cut the tape 21 into tape segments. The glue sticking mechanism 5 is located above the tooling plate 1, and the glue sticking mechanism 5 is used to press the tape segments onto the battery cell 11. The driving mechanism 6 includes a motor 61 and a transmission assembly 62. The motor 61 is connected to the clamping and pulling glue mechanism 3, the glue cutting mechanism 4 and the glue sticking mechanism 5 through the transmission assembly 62 to synchronously drive the clamping and pulling glue mechanism 3, the glue cutting mechanism 4 and the glue sticking mechanism 5.

[0057] In the embodiment of the present application, the battery cell 11 has an area to be glued. The area to be glued can be the tab area of ​​the battery cell 11 or the side surfaces of the main body of the battery cell 11. The embodiment of the present application does not specifically limit this. The gluing mechanism 5 is used to press the tape onto the area to be glued on the battery cell 11.

[0058] When the battery cell gluing device provided in the embodiment of the present application is used to glue the battery cell 11, the motor 61 in the drive mechanism 6 drives the clamping and gluing mechanism 3 to clamp the tape 21 through the transmission assembly 62 and drives the tape 21 to move horizontally, so that the tape 21 moves in a direction close to the tooling plate 1 and the battery cell 11. At the same time, the drive mechanism 6 controls the cutting mechanism 4 to move in a horizontal direction and perpendicular to the side of the tape 21, cutting the tape 21 delivered to the cutting mechanism 4 into tape segments. After the cutting mechanism 4 cuts the tape 21, the clamping jaws 33 of the clamping and gluing mechanism 3 are opened, and then the gluing mechanism 5 presses the tape 21 toward the battery cell 11, so that the cut tape segment is attached to the area of ​​the battery cell 11 to be glued, such as the tab of the battery cell 11, to achieve gluing of the battery cell 11.

[0059] In the battery cell gluing device provided in the embodiment of the present application, the gluing of the battery cell 11 is accomplished by the glue clamping and pulling mechanism 3, the glue cutting mechanism 4, and the glue applying mechanism 5, with a high degree of automation. Furthermore, driven by the glue clamping and pulling mechanism 3 on the battery cell 11, the adhesive tape 21 sequentially passes through the glue cutting mechanism 4 and the glue applying mechanism 5, and is pressed against the battery cell 11 by the glue applying mechanism 5. The conveying path of the adhesive tape 21 is short, and the various mechanisms cooperate closely, thereby increasing the gluing efficiency of the battery cell gluing device. Furthermore, the drive mechanism 6 uses the same motor 61 to synchronously drive multiple mechanisms, further improving the operating efficiency of the battery cell gluing device while reducing the size and energy consumption of the battery cell gluing device.

[0060] In some embodiments, such as Figure 2As shown, the driving mechanism 6 also includes a cylinder assembly (not shown). The clamping and pulling mechanism 3 includes a first clamping block 35 and a second clamping block 36. The cylinder assembly is connected to the first clamping block 35 and / or the second clamping block 36 to drive the first clamping block 35 and / or the second clamping block 36 to move in the vertical direction.

[0061] In the embodiment of the present application, the adhesive tape 21 is vertically positioned between the first clamping block 35 and the second clamping block 36. The cylinder assembly is used to drive the first clamping block 35 and / or the second clamping block 36 to move vertically so that the first clamping block 35 and the second clamping block 36 can jointly clamp the adhesive tape 21. In one example, the first clamping block 35 can be stationary. When it is necessary to clamp the adhesive tape 21, the cylinder assembly drives the second clamping block 36 to move closer to the first clamping block 35 until the first and second clamping blocks 35, 36 can clamp the adhesive tape 21. Conversely, when it is necessary to release the adhesive tape 21, the second clamping block 36 is controlled to move away from the first clamping block 35 to release the adhesive tape 21. In another example, the second clamping block 36 can be stationary. When it is necessary to clamp the adhesive tape 21, the cylinder assembly is used to drive the first clamping block 35 to move closer to the second clamping block 36 until the first and second clamping blocks 35, 36 can clamp the adhesive tape 21. Correspondingly, when the tape 21 needs to be loosened, the first clamping block 35 is controlled to move away from the second clamping block 36 to loosen the tape 21. In another example, the cylinder assembly can drive the first clamping block 35 and the second clamping block 36 to move. When the tape 21 needs to be clamped, the cylinder assembly drives the first clamping block 35 and the second clamping block 36 to move toward each other until the first clamping block 35 and the second clamping block 36 can clamp the tape 21. Correspondingly, when the tape 21 needs to be loosened, the first clamping block 35 and the second clamping block 36 are controlled to move away from each other to loosen the tape 21.

[0062] In some embodiments, such as Figure 1 As shown, the battery cell taping equipment further includes a glue preparation mechanism 2. The glue preparation mechanism 2 is located on the side of the glue cutting mechanism 4 away from the tooling plate 1. The glue preparation mechanism 2 is used to carry the adhesive tape 21 and convey the adhesive tape 21 toward the tooling plate 1. Specifically, the glue preparation mechanism 2 is used to carry the rolled adhesive tape 21. When the clamping and pulling mechanism 3 applies a pulling force to the adhesive tape 21 in a direction away from the glue preparation mechanism 2, the rolled adhesive tape 21 rotates under the action of the pulling force, thereby debonding the adhesive tape 21 and conveying a portion of the adhesive tape 21 toward the tooling plate 1 and the battery cell 11, thereby taping the battery cell 11.

[0063] In some embodiments, the transmission assembly 62 includes a cam drive group.

[0064] In some embodiments, such as Figure 2 and Figure 4As shown, the cam drive assembly includes a cam 621, a roller 622, a first connecting plate 623, and a connecting rod 624. The cam 621 is mounted on the first connecting plate 623, and abuts against the roller 622. One end of the connecting rod 624 is connected to the first connecting plate 623, and the other end of the connecting rod 624 is connected to the mechanism to be driven. The cam 621 drives the connecting rod 624 in the vertical direction through the roller 622 and the first connecting plate 623. The mechanism to be driven is at least one of the glue clamping and pulling mechanism 3, the glue cutting mechanism 4, and the glue applying mechanism 5.

[0065] In the embodiment of the present application, the cam driving group may include multiple cams 621, and the number of cams 621 corresponds to the number of mechanisms in the battery cell gluing device or the number of components that need to be driven in multiple mechanisms. Figure 6 As shown, the plurality of cams 621 include a first cam 6211, a second cam 6212, a third cam 6213, a fourth cam 6214, and a fifth cam 6215. The connection between the first cam 6211, the second cam 6212, the third cam 6213, the fourth cam 6214, and the fifth cam 6215 and the mechanism to be driven will be described below in conjunction with the structure of each mechanism to be driven, and will not be repeated here.

[0066] Further, such as Figure 2 As shown, the driving mechanism 6 can also include an output shaft 63 connected to the motor 61, and the output shaft 63 is connected to a plurality of cams 621. The motor 61 drives the output shaft 63 to rotate so that the plurality of cams 621 fixed on the output shaft 63 rotate synchronously, thereby realizing the synchronous driving of the various mechanisms in the battery cell gluing equipment by the motor 61. Among them, the connection between each mechanism and the cam 621 will be described below in conjunction with the specific structures of the clamping and pulling mechanism 3, the glue cutting mechanism 4 and the gluing mechanism 5, and will not be repeated here. Among them, the motor 61 drives the plurality of cams 621 through the output shaft 63, and then drives the connecting rod 624 connected thereto to perform reciprocating linear motion through the plurality of cams 621. The plurality of cams 621 move synchronously and the plurality of cams 621 do not interfere with each other, so that the stability of the cam drive group is relatively high.

[0067] Furthermore, the motor 61 drives multiple cams 621 to rotate synchronously through the output shaft 63, thereby driving the driven mechanisms connected to each cam 621 to operate. When the output shaft 63 rotates one circle, the multiple cams 621 rotate one circle accordingly, and each driving mechanism jointly completes a gluing process, making the battery cell gluing equipment more stable and sustainable.

[0068] Furthermore, the roller 622 and connecting rod 624 are disposed on the first connecting plate 623, and transmission is provided between the cam 621 and the connecting rod 624 via the first connecting plate 623, further enhancing the stability of the cam drive assembly during movement. Furthermore, the connecting rod 624 can also be directly connected to the cam 621 via the roller 622, although this embodiment of the present application does not specifically limit this.

[0069] In some embodiments, the output shaft 63 of the drive mechanism 6 is a worm gear output shaft. The cam drive group is driven by the worm gear output shaft, which increases the reduction ratio of the cam drive group and makes the torque of the output shaft 63 larger, thereby increasing the sustainability of the movement of the connecting rod 624.

[0070] In some embodiments, such as Figure 4 As shown, the connecting rod 624 includes a first section 6241 and a second section 6242, the first section 6241 and the second section 6242 are threadedly connected, and the threaded connection depth between the first section 6241 and the second section 6242 is adjustable. Figure 4 As shown, the upper end of the first section 6241 is connected to the mechanism to be driven, and the lower end of the second section 6242 is connected to the first connecting plate 623. Since the threaded screw-in depths of the first section 6241 and the second section 6242 are adjustable, the overall length of the connecting rod 624 can be adjusted by adjusting the threaded screw-in depths of the first section 6241 and the second section 6242. Therefore, the initial position of the movement of the connecting rod 624 and the position where the action is completed can be changed without replacing the connecting rod 624, thereby enabling the initial position of the movement of the connecting rod 624 and the position where the action is completed to be accurately adjusted.

[0071] In some embodiments, such as Figure 4 As shown, the cam drive group includes a first rod end bearing 625 and a second rod end bearing 626, one end of the connecting rod 624 is connected to the first connecting plate 623 through the first rod end bearing 625, and the other end of the connecting rod 624 is connected to the mechanism to be driven through the second rod end bearing 626.

[0072] In the embodiment of the present application, the mechanism to be driven may be the glue clamping and pulling mechanism 3, glue cutting mechanism 4, glue sticking mechanism 5, etc. of the battery cell glue sticking equipment. The first rod end bearing 625 and the second rod end bearing 626 both include a rod end and a bearing end. Figure 4 As shown, the rod end of the first rod end bearing 625 is connected to one end of the connecting rod 624, and the bearing end of the first rod end bearing 625 can be connected to the first connecting plate 623 via fasteners such as bolts and screws. Correspondingly, the rod end of the second rod end bearing 626 is connected to the other end of the connecting rod 624, and the bearing end of the second rod end bearing 626 is connected to the mechanism to be driven. There are various ways to connect the first rod end bearing 625 and the second rod end bearing 626 to the connecting rod 624, and this embodiment of the application does not specifically limit this.

[0073] In some embodiments, the first and second rod-end bearings 625, 626 are threadedly connected to the connecting rod 624, and the depth of the threaded connection between the connecting rod 624 and the first and second rod-end bearings 625, 626 is adjustable. By adjusting the depth of the two ends of the connecting rod 624 threaded into the first and second rod-end bearings 625, 626, the distance between the first and second rod-end bearings 625, 626 can be adjusted. Therefore, the initial position and the position at which the connecting rod 624 moves can be changed without replacing the connecting rod 624, thereby allowing precise adjustment of the initial position and the position at which the connecting rod 624 moves.

[0074] In some embodiments, the first rod end bearing 625 and the second rod end bearing 626 are connected to the connecting rod 624 by a key connection or an interference connection.

[0075] In some embodiments, the first rod end bearing 625 and the second rod end bearing 626 are welded to the connecting rod 624 .

[0076] In some embodiments, the driving mechanism 6 further includes an encoder 64, which is used to control the rotation angle of the cam 621. Figure 4 As shown, encoder 64 is disposed on output shaft 63. Encoder 64 is used to monitor the rotation angle of output shaft 63, thereby determining the rotation angles of multiple cams disposed on output shaft 63 at a specific moment or within a preset time period. This increases the positional accuracy and consistency of each cam 621 during operation and reduces the possibility of collisions between cams 621 due to positional deviations of one or more cams 621. Encoder 64 includes, but is not limited to, incremental encoders, absolute encoders, hybrid absolute encoders, and the like.

[0077] In some embodiments, such as Figure 1 and Figure 2 As shown, the adhesive preparation mechanism 2 includes a tape installation roller 22 and a brake 23 connected to the tape installation roller 22 . The tape 21 is installed on the tape installation roller 22 . The brake 23 is used to control the rotation state of the tape installation roller 22 .

[0078] In the embodiment of this application, Figure 1As shown, the battery cell gluing equipment includes a mounting plate 100, and a tape installation roller 22 is pivotally mounted on the mounting plate 100. The tape installation roller 22 is used to carry the rolled tape 21. When the clamping and pulling mechanism 3 pulls the tape 21 in the horizontal direction and away from the glue preparation mechanism 2, the tape installation roller 22 rotates under the action of the pulling force to achieve the unsealing and conveying of the tape 21. The brake 23 is used to apply resistance to the tape installation roller 22. When the brake 23 is turned on, the tape installation roller 22 stops rotating. The brake 23 is used to control the rotation state of the tape installation roller 22, such as controlling whether the tape installation roller 22 rotates, the rotation time, and the number of rotations. Specifically, when it is necessary to glue the battery cell 11, the brake 23 is closed, so that the tape installation roller 22 can rotate and convey the tape 21 to the battery cell 11 on the tooling plate 1. When it is no longer necessary to continue conveying the tape 21 toward the battery cell 11, the brake 23 is opened and the tape installation roller 22 stops rotating, limiting the amount of tape 21 being untied, thereby reducing the probability of excessive untiing of the tape 21 due to rotational inertia and other reasons during the conveying process of the tape 21, resulting in adhesion and wrinkling of the tape 21.

[0079] In some embodiments, the brake 23 includes a magnetic powder clutch.

[0080] In some embodiments, such as Figure 1 As shown, the battery cell gluing equipment also includes a debonding mechanism 7, which is located between the glue preparation mechanism 2 and the glue cutting mechanism 4. The debonding mechanism 7 is used to provide downward pressure on the tape 21 so that at least part of the tape 21 is separated from the glue preparation mechanism 2. Specifically, the tape installation roller 22 carries a tape roll, and the debonding mechanism 7 is used to apply downward pressure to the tape 21 so that part of the tape 21 is peeled off from the tape roll, thereby debonding the tape roll and conveying the debonded tape 21 toward the battery cell 11 to be glued. Furthermore, the length of at least part of the tape 21 peeled off from the tape roll is greater than or equal to the length of the tape segment used to be attached to the battery cell 11.

[0081] In some embodiments, the debonding mechanism 7 includes a first roller 71, a second roller 72 and a third roller 73 arranged on the mounting plate 100, the second roller 72 is located between the first roller 71 and the third roller 73, and the second roller 72 can move in the vertical direction, and the adhesive tape 21 passes through the highest point of the first roller 71, the lowest point of the second roller 72 and the highest point of the third roller 73 in turn.

[0082] In the embodiment of the present application, the first roller 71, the second roller 72, and the third roller 73 are all pivotally mounted on the mounting plate 100, that is, the first roller 71, the second roller 72, and the third roller 73 can all rotate around their own axes. During the process of conveying the adhesive tape 21 by the adhesive preparation mechanism 2 in the direction close to the battery cell 11, the adhesive tape 21 passes the lowest point of the second roller 72. The second roller 72 can move in the vertical direction, so the second roller 72 drives the adhesive tape 21 to move in the vertical direction, providing downward pressure on the adhesive tape 21. When the second roller 72 moves below the tape roll on the tape installation roller 22, part of the adhesive tape 21 is separated from the tape roll under the action of the second roller 72, thereby achieving the debonding of the adhesive tape 21.

[0083] The first and third rollers 71, 73 are located on either side of the second roller 72, respectively, and are used to support and guide the tape 21. Optionally, the tape roll is cylindrical, and along the height direction, the height of the axis of the first roller 71 is higher than the height of the lowest generatrix of the cylindrical tape roll, so that the tape 21 located between the tape installation roller 22 and the first roller 71 is tangent to the outer side of the tape roll or forms an acute angle with the tape roll, thereby reducing the tension required for debonding the tape 21 and ensuring the stability of the debonding mechanism 2.

[0084] In some embodiments, such as Figure 1 As shown, the battery cell gluing equipment also includes a first guide roller 8 and a second guide roller 9. The first guide roller 8 and the second guide roller 9 are located between the glue opening mechanism 7 and the glue cutting mechanism 4. The tape 21 passes through the lowest point of the first guide roller 8 and the highest point of the second guide roller 9 in sequence.

[0085] In the embodiment of the present application, the first guide roller 8 and the second guide roller 9 are used to support and guide the adhesive tape 21. When the adhesive tape 21 is conveyed from the adhesive preparation mechanism 2 toward the tooling plate 1, the adhesive tape 21 passes through the highest point of the first roller 71, the lowest point of the second roller 72, the highest point of the third roller 73, the lowest point of the first guide roller 8, and the highest point of the second guide roller 9 in sequence. The multiple rollers and guide rollers keep the adhesive tape 21 in a taut state, reducing the probability of adhesive tape adhesion and wrinkles.

[0086] In some embodiments, annular protrusions are provided at both ends of the roller, and the tape 21 is located between the two annular protrusions of each intermediate roller. The two annular protrusions limit the tape 21, reducing the probability of the tape 21 slipping off the intermediate roller during transmission, wherein the roller is at least one of the first roller 71, the second roller 72, the third roller 73, the first guide roller 8 and the second guide roller 9.

[0087] In some embodiments, the intermediate roller is coated with a coating to protect it and reduce corrosion. Furthermore, the coating is used to reduce adhesion between the tape 21 and the intermediate roller. Examples of coatings include, but are not limited to, Teflon coatings and ceramic coatings.

[0088] In some embodiments, a toothed structure is provided on the middle roller to reduce the contact area between the adhesive tape 21 and the middle roller, thereby further reducing the probability of adhesion between the adhesive tape 21 and the middle roller.

[0089] In some embodiments, the glue-unloading mechanism 7 further includes a first track 74 disposed on the mounting plate 100 and extending in the vertical direction, and the second roller 72 is slidably connected to the first track 74. The motor 61 is also used to synchronously drive the glue-unloading mechanism 3, the glue-cutting mechanism 4, the glue-applying mechanism 5, and the second roller 72.

[0090] In the embodiment of the present application, the motor 61 is also used to drive the second roller 72 through the transmission assembly 62. Further, the motor 61 drives the second roller 72 through the first cam 6211. Specifically, Figure 1 As shown, the degumming mechanism 7 further includes a first slider 75 slidably connected to the first rail 74, with the second roller 72 disposed on the first slider 75. A third pressure block 6243 is disposed at one end of a connecting rod 624, corresponding to and positioned above the first slider 75. The other end of the connecting rod 624 is connected to a first cam 6211, enabling the motor 61 to drive the first slider 75 and the second roller 72 via the first cam 6211 and the connecting rod 624. Specifically, the motor 61 drives the first cam 6211 to rotate via the output shaft 63. The roller 622 located above the first cam 6211 moves along the edge of the first cam 6211, thereby driving the first connecting plate 623 connected thereto to move vertically. This, in turn, drives the third pressure block 6243 connected thereto to move via the connecting rod 624, thereby causing the first slider 75 located below the third pressure block 6243 and the second roller 72 fixed to the first slider 75 to move vertically.

[0091] Specifically, during the debonding process, the first cam 6211 drives the third pressure block 6243 downward via the connecting rod 624, causing the third pressure block 6243 to strike the first slider 75, causing the first slider 75 and the second roller 72 to move downward. The first cam 6211 then continues to rotate, driving the connecting rod 624 and the third pressure block 6243 upward to reset. At this point, the first slider 75 and the second roller 72 remain positioned downward under their own weight, pressing against the adhesive tape 21. When the adhesive clamping and pulling mechanism 3 clamps and pulls the adhesive tape 21, it overcomes the weight of the first slider 75 and the second roller 72. This means that the adhesive clamping and pulling mechanism 3 drives the adhesive tape 21, and the adhesive tape 21 drives the first slider 75 and the second roller 72 upward to reset.

[0092] In some embodiments, such as Figure 3 and Figure 5 As shown, the battery cell gluing equipment further includes a glue pressing mechanism 10 , which is located on a side of the glue cutting mechanism 4 away from the tooling plate 1 , and is used to fix the adhesive tape 21 .

[0093] In the embodiment of this application, Figure 2 As shown, the glue pressing mechanism 10 is located between the glue cutting mechanism 4 and the second guide roller 9. When the tape 21 passes through the second guide roller 9 and reaches the glue pressing mechanism 10, the glue pressing mechanism 10 fixes the tape 21 so that when the glue cutting mechanism 4 cuts the tape 21, the tape 21 will not move or wrinkle, thereby reducing the difficulty of the cutting mechanism 4 in cutting the tape 21 and improving the efficiency of the glue cutting mechanism 4.

[0094] In some embodiments, the adhesive laminating mechanism 10 includes a support block 101 and an adhesive laminating slider 102 positioned above the support block 101. The adhesive laminating slider 102 is movable vertically, with the adhesive tape 21 positioned between the adhesive laminating slider 102 and the support block 101. The motor 61 is further connected to the adhesive laminating slider 102 via a transmission assembly 62 to synchronously drive the adhesive clamping and pulling mechanism 3, the adhesive cutting mechanism 4, the adhesive applying mechanism 5, and the adhesive laminating slider 102.

[0095] In the embodiment of the present application, as the adhesive tape 21 is being conveyed from the adhesive preparation mechanism 2 to the tooling plate 1, the adhesive tape 21 passes through the adhesive pressing mechanism 10, whereupon the adhesive tape 21 is positioned between the adhesive pressing slider 102 and the support block 101. The motor 61 drives the adhesive pressing slider 102 downward via the transmission assembly 62 until the adhesive pressing slider 102 contacts the support block 101, and the adhesive pressing slider 102 presses the adhesive tape 21 against the support block 101, thereby securing the adhesive tape 21.

[0096] Specifically, the motor 61 drives the adhesive laminating slider 102 to move vertically via the second cam 6212. The second cam 6212 in the transmission assembly 62 is connected to one end of a connecting rod 624 via a first connecting plate 623, and the other end of the connecting rod 624 is connected to the adhesive laminating slider 102. The motor 61 drives the second cam 6212 to rotate, causing the cam 6212 to drive the connecting rod 624 to move vertically via the first connecting plate 623, thereby driving the adhesive laminating slider 102 connected to the connecting rod 624 to move vertically.

[0097] Furthermore, during the gluing process, the brake 23 is closed, and the motor 61 drives the second roller 72 and the first slider 75 downward via the first cam 6211, so that the second roller 72 drives the tape 21 downward to achieve debonding. At this time, the support block 101 in the gluing mechanism 10 and the gluing slider 102 engage to fix the tape 21 between the support block 101 and the gluing slider 102. After the debonding is completed, the second cam 6212 drives the gluing slider 102 upward, causing the gluing mechanism 10 to open. At the same time, the clamping and pulling mechanism 3 drives the tape 21 to move, and the glue cutting mechanism 4 cuts the tape 21 into tape segments. The gluing mechanism 5 then attaches the tape segments to the battery cell 11, completing one gluing process.

[0098] In some embodiments, the upper surface of the support block 101 is coated with a coating to reduce the probability of adhesion between the tape 21 and the support block 101. The coating includes but is not limited to Teflon coating, ceramic coating, etc.

[0099] In some embodiments, the axis height of the second guide roller 9 is lower than the height of the upper surface of the support block 101 along the height direction. When the battery cell 11 is glued, the glue pressing slider 102 moves upward, and a portion of the tape 21 remains attached to the upper surface of the support block 101. When gluing the next battery cell 11, the glue clamping and pulling mechanism 3 continues to clamp the end of the tape 21 away from the glue preparation mechanism 2, and then the glue clamping and pulling mechanism 3 clamps the tape 21 and moves horizontally. Because the axis height of the second guide roller 9 is higher than the height of the upper surface of the support block 101, when the glue clamping and pulling mechanism 3 clamps the tape 21 and applies tension to the tape 21, the tape 21 detaches from the upper surface of the support block 101 and is then flattened and raised to a height approximately equal to that of the glue clamping and pulling mechanism 3 and the second guide roller 9. Therefore, the probability of the tape 21 adhering to the upper surface of the support block 101 is reduced, and the probability of the tape 21 wrinkling is reduced.

[0100] In some embodiments, such as Figure 3 and Figure 5 As shown, the glue pressing mechanism 10 further includes a third guide rail 103 disposed on the mounting plate 100 and a third slider 104 slidably connected to the third guide rail 103. The third guide rail 103 extends in the vertical direction. The third slider 104 is connected to the connecting rod 624, which is in turn connected to the glue pressing slider 102. When the motor 61 drives the second cam 6212 via the output shaft 63, the second cam 6212 drives the connecting rod 624 to move in the vertical direction via the first connecting plate 623, thereby driving the third slider 104 connected to the connecting rod 624 to move on the third guide rail 103, and further driving the glue pressing slider 102 connected to the third slider 104 to move in the vertical direction.

[0101] In some embodiments, such as Figure 1As shown, the gluing mechanism 5 includes a second guide rail 51 extending in the vertical direction and a pressing block structure 52 slidably connected to the second guide rail 51. A motor 61 is connected to the pressing block structure 52 via a transmission assembly 62 to drive the pressing block structure 52 to slide relative to the second guide rail 51. Specifically, the motor 61 drives the pressing block structure 52 to slide relative to the second guide rail 51 via a third cam 6213.

[0102] In the embodiment of the present application, the second guide rail 51 is provided on the mounting plate 100. The gluing mechanism 5 also includes a second slider 53 slidably connected to the second guide rail 51. The second slider 53 is connected to the connecting rod 624 of the transmission assembly 62, and the second slider 53 is connected to the pressure block structure 52. The motor 61 drives the connecting rod 624 to move in the vertical direction through the third cam 6213, thereby driving the second slider 53 connected to the connecting rod 624 to move on the second guide rail 51, and then drives the pressure block structure 52 connected to the second slider 53 to move in the vertical direction. During the gluing process of the battery cell 11, the pressure block structure 52 is controlled to move downward until it contacts the tape 21 and the tape 21 is attached to the area of ​​the battery cell 11 to be glued.

[0103] In some embodiments, the gluing mechanism 5 further includes a fourth guide rail 54 provided on the mounting plate 100 and a fourth slider 55 slidably connected to the fourth guide rail 54. The gluing mechanism 5 further includes a transmission member 56, which connects the second slider 53 and the fourth slider 55, and the pressing block structure 52 can be connected to the fourth slider 55. Since the second slider 53 and the fourth slider 55 are connected by the transmission member 56, the motor 61 drives the second slider 53 and the fourth slider 55 to move on the second guide rail 51 and the fourth guide rail 54 respectively, thereby driving the pressing block structure 52 connected to the fourth slider 55 to move in the vertical direction. Among them, the gluing mechanism 5 adopts a dual-guide rail structure (the second guide rail 51 and the fourth guide rail 54), which makes the pressing block structure 52 more stable during movement and makes the tape 21 attached to the battery cell 11 more flat.

[0104] In some embodiments, the pressure block structure 52 includes a first pressure block 521, at least one first connecting rod 522, at least one second connecting rod 523, and a second pressure block 524. The first pressure block 521 is connected to the transmission assembly 62, and the first pressure block 521 is connected to the second pressure block 524 via the at least one first connecting rod 522 and the at least one second connecting rod 523. At least one first connecting rod 522 or at least one second connecting rod 523 includes an elastic member.

[0105] In the embodiment of the present application, the tab extends from one end face of the battery cell 11. When the area of ​​the battery cell 11 to be glued is the tab of the battery cell 11, the tape 21 needs to cover the tab of the battery cell 11 and extend to the side surface of the battery cell 11 adjacent to the end face where the tab is located (hereinafter referred to as the large surface of the battery cell). There is a stepped transition between the tab of the battery cell 11 and the large surface of the battery cell. The first pressing block 521 and the second pressing block 524 are connected by the first connecting rod 522 or the second connecting rod 523. Since the first connecting rod 522 or the second connecting rod 523 has an elastic member, when the pressing block structure 52 moves downward as a whole to contact the large surface of the battery cell 11, the elastic member acts as a buffer for the pressing block structure 52 while providing space for the pressing block structure 52 to continue to move downward, so that part of the pressing block structure 52 continues to move downward to contact the tab of the battery cell, so that the tape 21 can be attached to the large surface of the battery cell and the tab of the battery cell. The connecting rod with the elastic member is located above the large surface of the battery cell, while the connecting rod without the elastic member is located above the tab of the battery cell.

[0106] In one example, the second pressing block 524 includes a first portion and a second portion, a first connecting rod 522 having an elastic member connected to the first portion, and a second connecting rod 523 connected to the second portion. After the pressing block structure 52 moves as a whole until it contacts the large surface of the battery cell, the pressing block structure 52 continues to move downward, and the elastic member on the first connecting rod 522 is compressed so that the first portion remains in contact with the large surface of the battery cell. The second portion continues to move downward until it contacts the tab of the battery cell 11. Under the action of the first and second portions, the tape 21 adheres to the large surface of the battery cell and the tab, achieving stepped adhesive application, so that the tape 21 adheres more evenly to the battery cell 11. The elastic member includes but is not limited to a spring, a spring, etc.

[0107] In some embodiments, such as Figure 3 As shown, the pressing block structure 52 includes two first connecting rods 522 and two second connecting rods 523 .

[0108] In some embodiments, the rubber cutting mechanism 4 includes a fixed block 41 and a cutter 42 disposed on the fixed block 41. The fixed block 41 is connected to a cam drive assembly. Under the action of the cam drive assembly, the fixed block 41 moves in a direction horizontally and perpendicular to the direction of tape transport, thereby driving the cutter 42 disposed on the fixed block 41 to move and cut the tape 21. Specifically, the fixed block 41 moves in a direction horizontally and perpendicular to the direction of tape transport under the action of the fourth cam 6214 in the cam drive assembly.

[0109] Furthermore, the rubber cutting mechanism 4 also includes a second connecting plate 43 disposed on the mounting plate 100, a fifth track 44 disposed on the second connecting plate 43, a fifth slider 45 slidably connected to the fifth track 44, and a third connecting plate 46. The fifth track 44 extends vertically. One end of the connecting rod 624 is connected to the fourth cam 6214 via the first connecting plate 623, and the other end is fixedly connected to the fifth slider 45. The third connecting plate 46 is pivotally mounted on the second connecting plate 43. One end of the third connecting plate 46 is fixedly connected to the fifth slider 45, and the other end of the third connecting plate 46 is fixedly connected to the fixed block 41.

[0110] Specifically, when the tape 21 needs to be cut by the tape cutting mechanism 4, the fourth cam 6214 drives the connecting rod 624 to move in the vertical direction, thereby driving the fifth slider 45 fixed thereto to slide relative to the fifth rail 44, and at the same time driving one end of the third connecting plate 46 fixedly connected to the fifth slider 45 to move in a roughly vertical direction. Since the third connecting plate 46 can rotate relative to the second connecting plate 43, the other end of the third connecting plate 46 moves in a roughly horizontal direction, thereby driving the fixed block 41 fixed to the third connecting plate 46 to move in the horizontal direction, and then driving the cutter 42 set on the fixed block 41 to move to cut the tape 21.

[0111] In some embodiments, a slot is provided on the fixing block 41 , and the cutter 42 is inserted into the slot.

[0112] In some embodiments, the fixing block 41 is connected to the cutter 42 by magnetic attraction.

[0113] In some embodiments, such as Figure 2 and Figure 4 As shown, the clamping and glue pulling mechanism 3 includes a sixth guide rail 31 disposed on the mounting plate 100 and extending horizontally, a sixth slider 32 slidably connected to the sixth guide rail 31, and a clamping jaw 33 fixedly connected to the sixth slider 32. A motor 61 is connected to the sixth slider 32 via a cam drive assembly to drive the sixth slider 32 to slide on the sixth guide rail 31, thereby driving the clamping jaw 33 fixedly connected to the sixth slider 32 to move horizontally. Specifically, the motor 61 drives the sixth slider 32 to slide relative to the sixth guide rail 31 via a fifth cam 6215 and a connecting rod 624.

[0114] Furthermore, the adhesive clamping and drawing mechanism 3 also includes a fourth connecting plate 34 pivotally mounted on the mounting plate 100. One end of the fourth connecting plate 34 is connected to the connecting rod 624, and the other end of the fourth connecting plate 34 is fixedly connected to the sixth slider 32. Specifically, the motor 61 drives the connecting rod 624 to move in the vertical direction via the fifth cam 6215, thereby driving one end of the fourth connecting plate 34 connected to the connecting rod 624 to move in the vertical direction. This then causes the entire fourth connecting plate 34 to rotate relative to the mounting plate 100, driving the other end of the fourth connecting plate 34 to move in the horizontal direction. This then drives the sixth slider 32, which is fixedly connected to the other end of the fourth connecting plate 34, to move on the sixth guide rail 31, thereby driving the clamping jaw 33 connected to the sixth slider 32 to move in the horizontal direction. Furthermore, when the clamping jaw 33 grasps the adhesive tape 21, it moves horizontally in a direction close to the adhesive application mechanism 5. After grasping the adhesive tape 21, the clamping jaw 33 drives the adhesive tape 21 to move horizontally in a direction away from the adhesive application mechanism 5.

[0115] In some embodiments, the battery cell taping apparatus includes a frame, on which the adhesive preparation mechanism 2, adhesive clamping and pulling mechanism 3, adhesive cutting mechanism 4, adhesive application mechanism 5, drive mechanism 6, adhesive opening mechanism 7, and adhesive pressing mechanism 10 are all disposed. Furthermore, a mounting plate 100 is fixedly connected to the frame. Furthermore, the drive mechanism 6 is disposed on the frame and below the mounting plate 100, which lowers the overall center of gravity of the battery cell taping apparatus and increases its stability.

[0116] In some embodiments, the transmission assembly 62 further includes an elastic structure connected to the cam 621. The elastic structure is used to apply pressure or tension to the cam 621, ensuring that the cam 621 remains in close contact with the roller 622 on the first connecting plate 623 during rotation, thereby enabling the roller 622 to move along the contour of the cam 621. Furthermore, the elastic structure can be positioned below the cam 621. During rotation of the cam 621, the elastic structure exerts upward pressure on the cam 621 through its own rebound force, ensuring that the cam 621 remains in close contact with the roller 622 above the cam 621 during rotation. The elastic structure can also be positioned above the cam 621. During rotation of the cam 621, the elastic structure exerts upward tension on the cam 621 through its own retraction force, ensuring that the cam 621 remains in close contact with the roller 622 above the cam 621 during rotation. Examples of elastic structures include, but are not limited to, springs, spring clips, and the like.

[0117] Specifically, in the embodiment of the present application, the cam 621 may include a first cam 6211, a second cam 6212, a third cam 6213, a fourth cam 6214 and a fifth cam 6215, and each cam 6215 is correspondingly provided with a first connecting plate 623. Among them, some of the five cams can adopt an upper fixing structure of an elastic structure, and the other part can adopt a lower fixing structure of an elastic structure, so that the space inside the battery cell gluing device can be fully utilized, thereby saving the internal space of the battery cell gluing device and reducing the volume of the battery cell gluing device. In an example, Figure 4 and Figure 6 As shown, the third cam 6213 (driving the glue laminating mechanism 5), the fourth cam 6214 (driving the glue cutting mechanism 4) and the fifth cam 6215 (driving the glue clamping and pulling mechanism 3) adopt an elastic structure lower fixed structure, and the first cam 6211 (driving the glue opening mechanism 7) and the second cam 6212 (driving the glue pressing mechanism 10) adopt an elastic structure upper fixed structure.

[0118] In the embodiment of the present application, the cam 621 can be connected to the mechanism to be driven via two connecting rods 624 (upper connecting rod 6244 and lower connecting rod 6245). Figure 4 As shown, the cam drive group also includes a first middle piece 627 and a second middle piece 628. The cam 621 is connected to one end of the lower connecting rod 6245 through the first connecting plate 623, the other end of the lower connecting rod 6245 is connected to one end of the first middle piece 627, the other end of the first middle piece 627 is connected to one end of the second connecting piece 628, one end of the second middle piece 628 is connected to one end of the upper connecting rod 6244, and the other end of the upper connecting rod 6244 is connected to the mechanism to be driven. Furthermore, the process of the cam 621 driving the mechanism to be driven through the upper connecting rod 6244 and the lower connecting rod 6245 is as follows: the cam 621 rotates to drive the lower connecting rod 6245 to move in the vertical direction, thereby driving one end of the first middle piece 627 to move in a substantially vertical direction, and then driving the first middle piece 627 to rotate around a fixed point ( Figure 4 The first intermediate member 627 drives the second intermediate member 628 fixedly connected thereto to rotate at a fixed point, thereby driving the upper connecting rod 6245 connected to one end of the second intermediate member 628 to move in the vertical direction, and finally drives the mechanism to be driven.

[0119] In particular, since when the cam 621 is an upper elastic structure fixed structure, the first connecting plate 623 is located below the center point of the cam 621, and when the cam 621 is a lower elastic structure fixed structure, the first connecting plate 623 is located above the center point of the cam 621, the length of the lower connecting rod 6245 corresponding to the upper elastic structure fixed structure of the cam 621 is greater than the length of the lower connecting rod 6245 corresponding to the lower elastic structure fixed structure of the cam 621. For example, Figure 4As shown, the length of the lower connecting rod 6245 corresponding to the second cam 6212 is greater than the length of the lower connecting rod 6245 corresponding to the fifth cam 6215 .

[0120] In the embodiment of the present application, when the battery cell gluing device is gluing, the brake 23 is closed, and the motor 61 drives the output shaft 63 to rotate, the glue pressing slider 102 in the glue pressing mechanism 10 is in contact with the support block 101 (the glue pressing mechanism 10 is closed), and at the same time, the second roller 72 of the glue unsealing mechanism 7 moves downward, driving the tape 21 to move downward, so that part of the tape 21 (the length is greater than the length of the required tape segment) is peeled off the tape roll, and the brake 23 is opened. Then the glue pressing slider 102 moves upward (the glue pressing mechanism 10 is opened), and at the same time, the clamping and pulling mechanism 3 clamps the tape 21 and drives the tape 21 forward. At the same time, the glue cutting mechanism 4 cuts the tape 21 transmitted to the glue cutting mechanism 4 into tape segments, and the glue cutting and applying mechanism 5 attaches the tape segments to the battery cell 11. At this time, the output shaft 63 rotates one circle, and a gluing process is completed. It can be seen that the stability and sustainability of the battery cell gluing device in the embodiment of the present application are relatively high. In addition, the various parts of the battery cell gluing equipment can operate synchronously. For example, when the glue cutting mechanism 4 completes glue cutting and the glue pressing mechanism 10 is in the glue pressing process, the glue preparation mechanism 2 can operate synchronously to open the glue, thereby improving the working efficiency of the entire equipment.

[0121] The second aspect of the embodiment of the present application provides a method for manufacturing a battery cell gluing device, such as Figure 7 As shown, the manufacturing method of the above-mentioned battery cell gluing device includes the following steps:

[0122] Provide tooling board, which is used to carry battery cells.

[0123] A clamping and pulling adhesive mechanism is provided, which is located above the tooling plate. The clamping and pulling adhesive mechanism is used to clamp the adhesive tape and drive the adhesive tape to move horizontally and in a direction close to the battery cell.

[0124] A rubber cutting mechanism is provided. The rubber cutting mechanism is located in front of the tooling plate along the conveying direction of the tape and is used to cut the tape into tape segments.

[0125] A gluing mechanism is provided, which is located above the tooling plate and is used to press the tape segment onto the battery cell.

[0126] A driving mechanism is provided, which includes a motor and a transmission assembly. The motor is connected to the clamping and pulling mechanism, the glue cutting mechanism and the glue sticking mechanism through the transmission assembly to synchronously drive the clamping and pulling mechanism, the glue cutting mechanism and the glue sticking mechanism.

[0127] In the battery cell gluing device manufactured according to the manufacturing method of the battery cell gluing device provided in the embodiment of the present application, the gluing of the battery cell is realized by the clamping and pulling mechanism, the glue cutting mechanism and the gluing mechanism, and the degree of automation is high. Driven by the clamping and pulling mechanism on the battery cell, the tape passes through the glue cutting mechanism and the gluing mechanism in sequence, and is pressed onto the battery cell under the action of the gluing mechanism. The conveying path of the tape is short, and the various mechanisms cooperate closely, which increases the gluing efficiency of the battery cell gluing device. In addition, the driving mechanism uses the same motor to synchronously drive multiple mechanisms, which further improves the working efficiency of the battery cell gluing device and reduces the volume and energy consumption of the battery cell gluing device.

[0128] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply the existence of any such actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article, or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or device. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not exclude the presence of other identical elements in the process, method, article, or device comprising the element.
