[0003] The present application relates to the technical field of battery manufacturing, and in particular to a gluing device, a battery production line, and an automatic gluing method. Background Art

[0004] Blue adhesive is widely used in battery production. During the battery production process, adhesive laminating equipment is often required to apply adhesive to battery cells. However, in some cases, when the blue adhesive roll runs out, the laminating equipment needs to replace the new roll, which is complicated and labor-intensive.

[0005] Summary of the Invention

[0006] The first aspect of the present application provides a glue-applying device, comprising: a glue preparation mechanism for storing film to be used; a glue unloading mechanism, comprising at least one film reel rotatable in both directions; and a shifting mechanism capable of transferring the film from the glue preparation mechanism to the film reel; the film reel can rotate in the opposite direction so that the film on the film reel winds the remaining film on the outside in the opposite direction to form an empty reel; the shifting mechanism can remove the empty reel from the film reel.

[0007] By setting up a film preparation mechanism, a shifting mechanism and a film release mechanism, the shifting mechanism can transfer the film from the film preparation mechanism to the film spool; when the film on the film spool has been consumed to a preset level, the film spool rotates in the opposite direction, and the film on the film spool winds the remaining film on the outside in the opposite direction to form an empty roll; in this way, automatic winding can be achieved, avoiding the residual film falling off and causing manual intervention, and then the shifting mechanism can automatically remove the empty roll from the film spool, completing the automatic loading of the film and the automatic unloading of the empty roll, without the need for manual reverse rotation of the film and manual removal of the empty roll, effectively saving manpower.

[0008] In one embodiment, the glue-applying device includes a glue-pulling mechanism and a glue-applying mechanism; the film has a radially protruding glue head; the glue-pulling mechanism can grab the glue head of the film on the film reel and pull out the film, and the glue-pulling mechanism can cut the film pulled out of the film into a fixed-length film; the glue-applying mechanism can grab the fixed-length film for pasting.

[0009] Through the mutual cooperation of the glue preparation mechanism, the shifting mechanism, the glue releasing mechanism, the glue pulling mechanism and the glue applying mechanism, the forward and reverse rotation of the film shaft is utilized; not only is the fully automatic glue applying process of the battery realized with high efficiency, controllable and stable quality, and the situation of film falling off and causing downtime is effectively avoided, but also the automatic loading of the film and the automatic unloading of the empty roll are realized, which saves manpower and reduces production costs.

[0010] In one embodiment, the film preparation mechanism includes at least one film reel, the film reel and the film reel being spaced relative to each other and coaxially disposed. The shift mechanism is at least partially movable between the film reel and the film reel. This allows the shift mechanism to transfer film from the film preparation mechanism to the film reel via linear motion, facilitating a streamlined structure.

[0011] In one embodiment, the glue preparation mechanism includes a first guide rail, a mounting portion, and a first driver. The material shaft is mounted on the mounting portion, which is movably disposed on the first guide rail. The first driver is in transmission connection with the mounting portion. The first driver drives the mounting portion to adjust its position, thereby offsetting the material shaft and the film reel, making it easier for an operator to place a ready-to-use film roll onto the material shaft. The first driver then drives the mounting portion to adjust its position, restoring the material shaft and the film reel to their coaxial position, thereby enabling automatic loading of the film by the shifting mechanism.

[0012] In one embodiment, the film preparation mechanism includes an empty film magazine, a second guide rail, and a second actuator. The empty film magazine is located below the area between the film spool and the material spool, and is movably mounted on the second guide rail. The second actuator is in transmission connection with the empty film magazine. The second actuator drives the empty film magazine along the second guide rail, allowing an operator to withdraw the empty film magazine from below the area between the film spool and the material spool, facilitating centralized cleaning of the empty film rolls.

[0013] In one embodiment, the shift mechanism includes a third guide rail, a gripping module, and a sixth actuator. The third guide rail is mounted between the film spool and the film preparation mechanism and includes a first working position at one end and a second working position at the other end. The gripping module is movably mounted on the third guide rail, and the sixth actuator is used to drive the gripping module to switch between the first and second working positions. Automatic film loading and empty film unloading are achieved by switching the gripping module between the first and second working positions. The entire process is fully automated, requiring no human intervention and enabling film changes without stopping the machine.

[0014] In one embodiment, the clamping module includes a base, at least two opposing clamping jaws, and a third actuator. The base is movably mounted on a third guide rail, and all the clamping jaws are movably mounted on the base. The third actuator is used to drive the clamping jaws toward or away from each other. The third actuator drives the opposing clamping jaws away from each other, with the distance between the clamping jaws being greater than the outer diameter of the film roll, allowing the clamping jaws to be smoothly positioned around the outer periphery of the film roll / empty roll. The third actuator then drives the opposing clamping jaws toward each other, thereby clamping the outer periphery of the film roll / empty roll. The clamping jaws, holding the film roll / empty roll, enable smooth removal from or insertion into the film spool / material shaft, facilitating automatic film loading and empty roll unloading by the shifting mechanism.

[0015] In one embodiment, the shifting mechanism includes a first sensor disposed on the base; the first sensor is capable of sensing the film on the film preparation mechanism.

[0016] In one embodiment, the film unwinding mechanism includes a support portion and a fourth driver. The film reel is rotatably mounted on the support portion. The fourth driver is fixed to the support portion and is in transmission connection with the film reel. The fourth driver drives the film reel to rotate forward or reverse, thereby automatically winding the empty reel, effectively preventing film dropout and other downtimes. This enables automatic film loading and unloading, saving labor and reducing production costs.

[0017] In one embodiment, the unloading mechanism includes a push plate assembly and a fifth actuator. The fifth actuator is drivingly connected to the push plate assembly, which is capable of axially pushing the empty film roll from the film spool. The push plate assembly allows the empty roll to be smoothly separated from the film spool, facilitating gripper removal and enabling the shift mechanism to automatically unload the empty roll.

[0018] In one embodiment, the glue releasing mechanism includes a second sensor disposed on the support portion, the second sensor being used to sense the outer diameter of the film on the film spool; and / or, the glue releasing mechanism includes a third sensor disposed on the support portion, the third sensor being used to identify the rotation angle of the film on the film spool.

[0019] In one embodiment, the glue pulling mechanism includes a first clamping jaw assembly, a roller assembly, a cutting assembly, and a second clamping jaw assembly; the first clamping jaw assembly is capable of grabbing the glue head and driving the film of the film roll to pass through the roller assembly laterally in a first direction; the roller assembly is used to tension the film of the film roll; the second clamping jaw assembly is capable of grabbing the glue head from the first clamping jaw assembly and forming a fixed-length film between the second clamping jaw assembly and the first clamping jaw assembly, and the cutting assembly is used to cut the fixed-length film. The first clamping jaw assembly, the roller assembly, the cutting assembly, and the second clamping jaw assembly cooperate with each other to form a fixed-length film between the first clamping jaw assembly and the second clamping jaw assembly. The cutting assembly cuts the fixed-length film, separating the fixed-length film from the film roll, and the glue sticking mechanism grabs the fixed-length film and transfers it to the corresponding workstation for adhesion with the battery, thereby completing the automatic glue sticking process.

[0020] In one embodiment, the first clamping jaw assembly includes a fourth guide rail, a seventh actuator, and a first clamping jaw. Along the first direction, the fourth guide rail includes a fifth working position at one end and a sixth working position at the other end. The fifth and sixth working positions are located at opposite ends of the roller assembly along the first direction. When the first clamping jaw is in the fifth working position, the first clamping jaw can grasp the rubber head of the film on the film spool. The seventh actuator is used to drive the first clamping jaw to switch between the fifth and sixth working positions. When the first clamping jaw is in the fifth working position, the first clamping jaw can grasp the rubber head of the film on the film spool. Driven by the seventh actuator, the first clamping jaw switches from the fifth working position to the sixth working position, and the first clamping jaw can pull the rubber head of the film from the fifth working position through the roller assembly to the sixth working position, thereby automatically threading the film through the roller assembly, avoiding the manual threading process and effectively saving manpower.

[0021] In one embodiment, the second clamp assembly includes a fifth guide rail, an eighth driver, and a second clamp; along the first direction, the fifth guide rail includes a seventh working position close to the first clamp and an eighth working position away from the first clamp; the eighth driver is used to drive the second clamp to switch between the seventh and eighth working positions. By setting the second clamp in the seventh working position, the second clamp can grab the film from the first clamp. Driven by the eighth driver, the second clamp moves from the seventh working position to the eighth working position on the right side. During the movement, the first clamp is slightly loosened, allowing the second clamp to continue grabbing the film and extend a distance to the right along the first direction. Finally, the first and second clamps jointly clamp the film, thereby forming a fixed-length film between the first and second clamps, which is convenient for cutting.

[0022] In one embodiment, the roller assembly includes multiple rollers and a ninth driver configured to drive the rollers to rise or fall in a third direction. The rollers maintain tension on the film roll, preventing wrinkles from forming after the cutter assembly cuts the film to length.

[0023] In one embodiment, the cutting assembly includes a cutting knife and a tenth driver; along the first direction, the cutting knife is arranged between the second clamping jaw and the first clamping jaw; the tenth driver is used to drive the cutting knife to reciprocate horizontally along the second direction, and the second direction is arranged to intersect with the first direction.

[0024] In one embodiment, the glue-applying mechanism includes a driving unit, an action arm, and a negative pressure suction cup; the negative pressure suction cup is arranged at the end of the action arm, and the driving unit drives the action arm to move up and down.

[0025] A second aspect of the present application provides a battery production line, comprising the above-mentioned glue laminating equipment.

[0026] The third aspect of the present application provides an automatic glue-laminating method, comprising: controlling the film spool to rotate in reverse so that the film on the film spool winds the remaining film on the outside in reverse to form an empty roll; controlling the shifting mechanism to remove the empty roll from the film spool; and controlling the shifting mechanism to transfer the film stored in the glue preparation mechanism to the film spool of the glue release mechanism.

[0027] In one embodiment, after the step of controlling the shift mechanism to transfer the film stored in the film preparation mechanism to the film reel of the film dispensing mechanism, the method further includes:

[0028] Control the film reel to rotate forward until the glue head of the film is aligned with the glue pulling mechanism; control the glue pulling mechanism to grab the glue head and pull out the film, and cut it into a fixed length film; control the glue sticking mechanism to grab the fixed length film and stick it to the battery cell.

[0029] In one embodiment, the steps of controlling the rubber pulling mechanism to grab the rubber head and pull out the film, and cutting it to a fixed length to form a fixed-length film include: controlling the first clamping jaw assembly to grab the rubber head; controlling the first clamping jaw assembly to drive the rubber head to pass through the roller assembly laterally along the first direction; controlling the second clamping jaw assembly to grab the rubber head on the first clamping jaw assembly; controlling the roller assembly to tension the film on the film roll; controlling the second clamping jaw assembly to move laterally to form a fixed-length film between the second clamping jaw assembly and the first clamping jaw assembly; and controlling the cutting assembly to cut the fixed-length film.

[0061] Currently, market developments indicate that power batteries are becoming increasingly widely used. Power batteries are not only used in energy storage systems such as hydropower, thermal, wind, and solar power plants, but are also widely used in electric vehicles like electric bicycles, electric motorcycles, and electric vehicles, as well as in aerospace and other fields. As power battery applications continue to expand, market demand is also growing.

[0062] During battery production, gluing equipment is often required to apply film to the battery cells. Because the gluing equipment relies on grippers to pull the film from the roll, the film cannot be completely pulled out, otherwise the film will detach from the roller at the center of the roll, causing equipment to malfunction. In related technologies, when the film on the roll is nearly used up, it is often necessary to manually rotate the roll in the opposite direction to collect the remaining film to form an empty roll. The empty roll must then be manually removed and replaced with a new roll of film. This is not only complicated but also wastes manpower.

[0063] A first aspect of the present application provides a gluing device, which is used to perform a corresponding gluing process on a battery cell using a film roll 90 .

[0064] Referring to Figures 1 to 8, Figure 1 is a schematic structural diagram of a glue laminating device provided in some embodiments of the present application; Figure 2 is a schematic structural diagram of a glue laminating device provided in some embodiments of the present application from another perspective; Figure 3 is a schematic assembly diagram of a glue preparation mechanism and a film provided in some embodiments of the present application; Figure 4 is a schematic assembly diagram of a shift mechanism and a film provided in some embodiments of the present application; Figure 5 is a schematic structural diagram of a shift mechanism provided in some embodiments of the present application; Figure 6 is a schematic assembly diagram of a glue dispensing mechanism and a film provided in some embodiments of the present application; Figure 7 is a schematic structural diagram of the structure shown in Figure 6 from another perspective; Figure 8 is a schematic diagram of the positional relationship of a glue preparation mechanism, a shift mechanism, and a glue dispensing mechanism provided in some embodiments of the present application. The glue laminating device includes: a glue preparation mechanism 100, a shift mechanism 200, and a glue dispensing mechanism 300.

[0065] The film preparation mechanism 100 is used to store the film rolls 90 to be used. The film dispensing mechanism 300 includes at least one bidirectionally rotatable film spool 310. The shifting mechanism 200 is movably disposed between the film preparation mechanism 100 and the shifting mechanism 200. The shifting mechanism 200 is capable of transferring the film rolls 90 from the film preparation mechanism 100 to the film spool 310. As the film spool 310 rotates in the forward direction, the film rolls 90 on the film spool 310 are discharged, and the film is then pulled out by the corresponding film pulling mechanism 400 (described below) for cutting.

[0066] When the film 90 on the film spool 310 has been consumed to a preset level, the film spool 310 rotates in the opposite direction, and the film 90 on the film spool 310 winds the remaining film on the outside in the opposite direction to form an empty reel 90b; in this way, automatic winding can be achieved, avoiding the remaining film on the film 90 from falling off and causing manual intervention, thereby enabling the shift mechanism 200 to automatically remove the empty reel 90b from the film spool 310; in this way, there is no need for operators to stop the machine, which improves the production efficiency of the gluing equipment; through the two-way rotation of the film spool 310 and in conjunction with the shift mechanism 200, the automatic loading of the film 90 and the automatic unloading of the empty reel 90b are completed, without the need for manual reverse rotation of the film 90 and manual removal of the empty reel 90b, which effectively saves manpower.

[0067] It should be understood that forward rotation and reverse rotation are relative concepts. For example, forward rotation of the film spool 310 may be clockwise, allowing the film 90 to unwind as the film spool 310 rotates forward. Reverse rotation of the film spool 310 is counterclockwise, allowing the film 90 to rewind any remaining film to form an empty spool 90b. Accordingly, forward rotation of the film spool 310 may be counterclockwise, while forward rotation of the film spool 310 is clockwise. The specific design is subject to change.

[0068] For ease of description, in the following embodiments, the film spool 310 drives the film 90 to rotate clockwise as forward rotation, at which time the film 90 releases the film outward, and the film spool 310 drives the film 90 to rotate counterclockwise as reverse rotation, at which time the film 90 reversely winds the remaining film outside.

[0069] The film 90 is placed on the film reel 310. Under the action of the glue pulling mechanism 400, a section of the film of the film 90 is pulled outward for fixed-length cutting. When the film 90 on the film reel 310 needs to be replaced, the film 90 originally placed on the film reel 310 needs to be retracted as the remaining film outside to avoid the section of film being entangled in the glue laminating equipment and affecting the use of the equipment.

[0070] In some embodiments, the film spool 310 is an inflatable spool. The film spool 310 can be inflated to expand, maintaining a larger diameter. This facilitates the attachment of the film roll 90 to the spool 310 and allows for forward or reverse rotation. When the film spool 310 needs to be replaced with a new film roll 90, the spool 310 can be deflated, reducing its size. The diameter of the spool 310 becomes smaller than the mounting hole (not shown) in the middle of the film roll 90, and the film spool 310 and film roll 90 are no longer relatively fixed. The film roll 90 and the empty film roll 90b can then be smoothly removed from or inserted into the spool 310, facilitating the automatic loading of the film roll 90 and the unloading of the empty film roll 90b by the shift mechanism 200.

[0071] In some possible embodiments, referring to Figures 9 to 11, Figure 9 is a schematic diagram of the structure of a glue pulling mechanism provided in some embodiments of the present application; Figure 10 is a top view of the glue pulling mechanism provided in some embodiments of the present application; and Figure 11 is a schematic diagram of the structure of a glue applying mechanism provided in some embodiments of the present application. The glue applying device includes a glue pulling mechanism 400 and a glue applying mechanism 500.

[0072] The film 90 has a radially protruding rubber head 91. The rubber pulling mechanism 400 can grab the rubber head 91 of the film 90 on the film spool 310 and pull out the film. The rubber pulling mechanism 400 can cut the film pulled out of the film 90 into a fixed-length film 90c.

[0073] In each embodiment of the present application, each unused film roll 90 has a rubber head 91. The rubber head 91 can be a hard sheet formed by winding the film roll itself, or it can be formed by connecting a customized card with the film roll 90. The specific design shall prevail.

[0074] Specifically, the film spool 310 drives the film 90 in forward rotation. When rotated to a certain angle, the adhesive head 91 aligns with the adhesive pull mechanism 400, making it easier for the adhesive pull mechanism 400 to grasp the adhesive head 91. The adhesive pull mechanism 400 pulls the adhesive head 91 outward, and the film spool 310 cooperates with the adhesive pull mechanism 400, thereby driving the film 90 to continuously rotate forward, releasing a continuous film. The glue pulling mechanism 400 can cut the film 90 on the film reel 310 into fixed-length films 90c, and the glue pasting mechanism 500 can grab the fixed-length films 90c for pasting; when the film 90 on the film reel 310 has been consumed to a preset extent, the film reel 310 rotates in the opposite direction, and the film 90 on the film reel 310 reversely rolls the remaining film in the glue pulling mechanism 400 to form an empty reel 90b, and the shifting mechanism 200 can remove the used empty reel 90b from the film reel 310, and transfer the film 90 to be used from the glue preparation mechanism 100 to the film reel 310 again, so that the next round of production process can be automatically started.

[0075] In this way, through the mutual cooperation of the glue preparation mechanism 100, the shifting mechanism 200, the glue release mechanism 300, the glue pulling mechanism 400 and the glue applying mechanism 500, the forward and reverse rotation of the film shaft 310 is utilized; not only is the fully automatic glue applying process of the battery realized with high efficiency, controllable and stable quality, and effective avoidance of shutdown caused by film falling off, but also the automatic loading of the film 90 and the automatic unloading of the empty roll 90b are realized, saving manpower and reducing production costs.

[0076] In some possible embodiments, referring to Figures 1 to 3 and Figure 8 , the glue preparation mechanism 100 includes at least one material shaft 110. The material shaft 110 is used to store the film rolls 90 to be used. Depending on the design requirements, the glue preparation mechanism 100 can store one or more film rolls 90 and install them in series on the material shaft 110 for easy access by the shifting mechanism 200.

[0077] The film reel 310 and the material reel 110 are spaced apart from each other and are coaxially arranged. The shift mechanism 200 is at least partially movably arranged between the film reel 310 and the material reel 110. As such, the shift mechanism 200 can transfer the film 90 from the film preparation mechanism 100 to the film reel 310 through linear motion without requiring corresponding lifting or turning, thereby simplifying the structure.

[0078] In some embodiments, the shaft 110 is an inflatable shaft. It can be inflated to expand its diameter, thus facilitating the attachment of the film roll 90 to the shaft 110. When the film roll 310 needs to be replaced with a new film roll 90, the shaft 110 can be deflated, reducing its size. The diameter of the shaft 110 is smaller than the mounting hole in the middle of the film roll 90, and the shaft 110 and film roll 90 are no longer fixed relative to each other. The shifting mechanism 200 can then smoothly remove the film roll 90 to be used from the shaft 110 and transfer it to the film roll 310, thus completing the automatic loading process of the film roll 90.

[0079] In some possible embodiments, referring to FIG. 1 to FIG. 3 and FIG. 8 , the glue preparation mechanism 100 includes a first guide rail 120 , a mounting portion 130 , and a first driver (not shown);

[0080] The mounting portion 130 can be a plate or frame, and can be made of metal such as carbon steel or stainless steel. The feed shaft 110 is mounted on the mounting portion 130, which is movably mounted on the first guide rail 120. A first driver is in transmission connection with the mounting portion 130. The first driver is configured to drive the mounting portion 130 along the first guide rail 120. This allows the first driver to drive the mounting portion 130 for position adjustment, thereby offsetting the feed shaft 110 and the film spool 310. This facilitates the operator's placement of the film roll 90 to be used onto the feed shaft 110. The first driver then drives the mounting portion 130 for position adjustment, restoring the feed shaft 110 and the film spool 310 to their coaxial position, thus enabling automatic loading of the shift mechanism 200.

[0081] In some embodiments, the first actuator may be a cylinder or a motor.

[0082] In some possible embodiments, referring to FIG. 1 to FIG. 3 and FIG. 8 , the film preparation mechanism 100 includes an empty film roll chamber 140 , a second guide rail 150 , and a second driver (not shown).

[0083] The empty film chamber 140 is a slot structure with an open top, used to store empty film rolls 90b removed from the film spool 310. Specifically, the empty film chamber 140 is located below the area between the film spool 310 and the material spool 110. When the film 90 on the film spool 310 has been consumed to a predetermined level, the shift mechanism 200 can remove the empty film roll 90b from the film spool 310 and release the corresponding fixed jaws at a predetermined position, allowing the empty film roll 90b to fall into the empty film chamber 140 below, making it easier for operators to clean it. The shift mechanism 200 then transfers the unused film 90 from the film preparation mechanism 100 to the film spool 310. The entire process is fully automated, requiring no human intervention, and allows for the replacement of film rolls 90 without stopping the machine.

[0084] The empty film compartment 140 is movably mounted on the second guide rail 150. A second actuator is in transmission connection with the empty film compartment 140. The second actuator is used to drive the empty film compartment 140 along the second guide rail 150. The operator removes the empty film compartment 140 from below the area between the film spool 310 and the material spool 110, facilitating centralized cleaning of the empty film rolls 90b therein.

[0085] In some embodiments, the second actuator may be a cylinder or a motor.

[0086] In some possible embodiments, referring to FIG. 1 , FIG. 2 , FIG. 4 , FIG. 5 and FIG. 8 , the shifting mechanism 200 includes a third guide rail 210 , a clamping module 220 and a sixth driver 230 .

[0087] The third guide rail 210 is mounted between the film spool 310 and the glue preparation mechanism 100. The third guide rail 210 extends generally parallel to the axial direction of the film spool 110. The third guide rail 210 includes a first working position at one end and a second working position at the other end. The first working position is the end of the third guide rail 210 closest to the glue preparation mechanism 100, while the second working position is the opposite end of the third guide rail 210, closest to the glue dispensing mechanism 300.

[0088] The clamping module 220 is movably disposed on the third guide rail 210 . The sixth driver 230 is in transmission connection with the clamping module 220 . The sixth driver 230 is used to drive the clamping module 220 to switch between the first working position and the second working position.

[0089] Specifically, when the sixth driver 230 drives the clamping module 220 to reach the first working position on the right, the clamping module 220 can clamp the film 90 to be used from the material shaft 110 of the glue preparation mechanism 100; the sixth driver 230 drives the clamping module 220 to move from the first working position to the second working position, and the clamping module 220 can transfer the film 90 to be used to the film shaft 310.

[0090] 8 , when the film 90 on the film spool 310 has been consumed to a predetermined level, the gripping module 220 moves leftward to the second working position, removes the empty film roll 90b from the film spool 310, and drops the empty film roll 90b into the empty film chamber 140 below at a predetermined position. Finally, the gripping module 220 moves rightward back to the first working position to re-grip the film roll 90 to be used from the material spool 110 of the film preparation mechanism 100.

[0091] The above process is repeated to realize automatic loading of the film 90 and automatic unloading of the empty roll 90b. The whole process is fully automated without manual intervention, and the film 90 can be replaced without stopping the machine.

[0092] In some embodiments, the sixth driver 230 may be a stepper motor, a servo motor, or a cylinder.

[0093] In some possible embodiments, referring to FIG. 1 , FIG. 2 , FIG. 4 , FIG. 5 and FIG. 8 , the clamping module 220 includes a base 221 , at least two clamping jaws 222 oppositely disposed, and a third driver 223 .

[0094] The base 221 is movably disposed on the third guide rail 210 , and all the clamping jaws 222 are movably disposed on the base 221 . The third driver 223 is used to drive the clamping jaws 222 to move closer to or away from each other.

[0095] The third actuator 223 can be a pneumatic cylinder, the cylinder body of which is fixed to the base 221, and the clamping jaws 222 are fixed to the ends of the movable rod of the third actuator 223. In conjunction with the orientation shown in FIG4 , air is supplied from different air inlet positions of the pneumatic cylinder to cause the movable rod to extend or retract, thereby moving the clamping jaws 222 toward or away from each other. A single third actuator 223 can drive all the clamping jaws 222 toward or away from each other. Alternatively, two or more third actuators 223 can each drive one clamping jaw 222, thereby achieving closer or farther movement.

[0096] Specifically, the sixth driver 230 drives the base 221 to reach the first working position, and the third driver 223 drives the relatively arranged jaws 222 to move away from each other. The distance between the jaws 222 is greater than the outer diameter of the film 90, so that the jaws 222 can be smoothly placed on the outer peripheral side of the film 90 / empty reel 90b. The third driver 223 then drives the relatively arranged jaws 222 to move closer to each other, thereby clamping the outer peripheral side of the film 90 / empty reel 90b. The jaws 222 clamp the film 90 / empty reel 90b and can smoothly take it out or put it in from the film shaft 310 / material shaft 110, which facilitates the shifting mechanism 200 to complete the automatic loading of the film 90 and the automatic unloading of the empty reel 90b.

[0097] In some possible embodiments, referring to FIG. 4 , the shifting mechanism 200 includes a first sensor 240 disposed on the base 221 ; the first sensor 240 can sense the film 90 on the film preparation mechanism 100 .

[0098] The first sensor 240 may be a position sensor or a photoelectric sensor.

[0099] Specifically, when the sixth driver 230 drives the base 221 to move toward the first working position, when the first sensor 240 senses the film 90 on the glue preparation mechanism 100, the first sensor 240 sends a corresponding signal to facilitate the determination of the position of the first working position, so that the clamping claw 222 can clamp the film 90 to be used from the material shaft 110 of the glue preparation mechanism 100; and facilitate the shifting mechanism 200 to complete the automatic loading of the film 90.

[0100] In some possible embodiments, referring to FIG. 1 , FIG. 2 , and FIG. 6 to FIG. 8 , the glue dispensing mechanism 300 includes a supporting portion 320 and a fourth driver 330 .

[0101] The support portion 320 can be a plate or frame and can be made of metal such as carbon steel or stainless steel. One end of the film shaft 310 is rotatably mounted on the support portion 320 ; the other end of the film shaft 310 protrudes axially from the support portion 320 to carry the film 90 .

[0102] The fourth driver 330 is fixed to the support portion 320 and is in transmission connection with the film spool 310. The fourth driver 330 drives the film spool 310 to rotate forward or reverse, thereby automatically winding the empty film roll 90b, effectively preventing film dropouts and other downtimes. This enables automatic loading of the film roll 90 and automatic unloading of the empty film roll 90b, saving manpower and reducing production costs.

[0103] In some embodiments, the fourth driver 330 may be a motor.

[0104] In some embodiments, referring to Figures 1, 2, and 6 to 8, the glue releasing mechanism 300 includes a push plate assembly and a fifth driver 360; the fifth driver 360 is transmission-connected to the push plate assembly, and the push plate assembly can push the empty roll 90b on the film shaft 310 out axially.

[0105] The push plate assembly may include a fixing seat 340 , a push plate 350 , and a sixth guide rail 341 .

[0106] The sixth guide rail 341 is mounted on the fixing base 340, and the support portion 320 is movably mounted on the sixth guide rail 341. The sixth guide rail 341 may extend parallel to the axial direction of the film spool 310. The sixth guide rail 341 includes a third working position at one end and a fourth working position at the other end.

[0107] The fifth actuator 360 is in transmission connection with the support portion 320 and is used to switch the support portion 320 between the third and fourth working positions. The push plate 350 is fixedly connected to the fixing base 340 and is located around the film spool 310. When the support portion 320 is in the fourth working position, the push plate 350 can push the film 90 / empty spool 90b off the film spool 310.

[0108] 7 , the current support portion 320 is in the fifth working position, the film reel 310 can rotate forward to allow the film 90 to output the film, and the corresponding film pulling mechanism 400 can be used to pull out the film for cutting. When the film 90 on the film spool 310 has been consumed to a preset extent, the film spool 310 rotates in the reverse direction, and the film 90 on the film spool 310 winds the remaining film on the outside in the reverse direction to form an empty reel 90b; along the direction from the upper right to the lower left, the fifth driver 360 pulls the support part 320 to move to the fourth working position, and the support part 320 drives the film spool 310 to move to the lower left, thereby causing the empty reel 90b on the film spool 310 to conflict with the push plate 350; the film spool 310 can be reduced in size, so that under the action of the push plate 350, the empty reel 90b is smoothly separated from the film spool 310 and is grasped and taken out by the clamping claw 222, which facilitates the shifting mechanism 200 to complete the automatic unloading of the empty reel 90b.

[0109] In some embodiments, the fifth driver 360 may be a motor or a cylinder.

[0110] 6 and 7 , the adhesive dispensing mechanism 300 includes a second sensor 370 disposed on the support portion 320. The second sensor 370 may be a through-beam optical fiber, a photoelectric sensor, or a position sensor.

[0111] The second sensor 370 is used to sense the outer diameter of the film 90 on the film spool 310. In this way, the second sensor 370 can timely sense the degree of film consumption on the film spool 310. When the film 90 rotates forward, the output film is cut to a fixed length and then pasted. The outer diameter of the film 90 also shrinks as the film is continuously output. When the outer diameter of the film 90 shrinks to a preset value, such as 100 mm, 90 mm, or other settable values, the second sensor 370 senses the outer diameter of the film 90 and sends a corresponding signal. After receiving the signal, the controller (not shown) of the gluing device determines whether the film 90 is used up. The film 90 on the spool 310 has been consumed to a preset extent and needs to be replaced with a new film 90; at this time, the film spool 310 is controlled to rotate in the opposite direction, and the film 90 on the film spool 310 reversely winds the remaining film on the outside to form an empty spool 90b, thereby realizing automatic winding and avoiding manual intervention caused by the remaining film on the film 90 falling off, thereby enabling the shifting mechanism 200 to remove the empty spool 90b from the film spool 310, and cooperating with the shifting mechanism 200 to complete the automatic unloading of the empty spool 90b, without the need for manual monitoring of the use of the film 90, effectively saving manpower.

[0112] 6 and 7 , the adhesive dispensing mechanism 300 includes a third sensor 380 disposed on the support portion 320. The third sensor 380 may be an angle sensor, a charge coupled device (CCD) camera, or the like.

[0113] The third sensor 380 is used to identify the rotation angle of the film 90 on the film spool 310. The film spool 310 can drive the film 90 to rotate in the forward direction. When the film 90 rotates to a certain angle, the third sensor 380 can identify the edge of the side of the adhesive head 91 of the film 90 and determine the angular position of the adhesive head 91 itself. This allows the adhesive head 91 to be aligned with the adhesive pulling mechanism 400, making it easier for the adhesive pulling mechanism 400 to grasp the adhesive head 91.

[0114] In some embodiments, as shown in Figures 6 and 7 , the adhesive dispensing mechanism 300 includes a fourth sensor 390 disposed on the support portion 320. The fourth sensor 390 can be a photoelectric sensor, a CCD camera, etc. The third sensor 380 can identify by color whether the film 90 on the film spool 310 is placed upside down and issue a corresponding alarm signal to ensure normal operation of the adhesive dispensing device.

[0115] In some possible embodiments, referring to Figures 1, 2, and 9 to 14, Figures 12 to 14 are schematic diagrams illustrating the positional relationship between the adhesive dispensing mechanism, adhesive pulling mechanism, and adhesive application mechanism provided in some embodiments of the present application. The adhesive pulling mechanism 400 includes a first clamping jaw assembly 410, a roller assembly 420, a cutting assembly 440, and a second clamping jaw assembly 430.

[0116] The first clamping jaw assembly 410 can grasp the film head 91 and drive the film 90 to pass through the roller assembly 420 along a first direction. The first direction is generally one direction in the horizontal plane and intersects the axial direction of the film shaft 310.

[0117] The roller assembly 420 is used to tension the film of the film roll 90; the second clamping assembly 430 can grab the rubber head 91 from the first clamping assembly 410 and form a fixed-length film 90c between the second clamping assembly 430 and the first clamping assembly 410, and the cutting assembly 440 is used to cut and form the fixed-length film 90c.

[0118] Specifically, the film spool 310 rotates forward under the drive of the fourth driver 330. When rotated to a certain angle, the adhesive head 91 is aligned with the adhesive pulling mechanism 400, facilitating the first clamping assembly 410 to grasp the adhesive head 91. The first clamping assembly 410 drives the film 90 to pass through the roller assembly 420 in a first direction. The film spool 310 cooperates with the first clamping assembly 410, thereby driving the film 90 to continuously rotate forward and release a continuous film. After the first clamping jaw assembly 410 reaches the predetermined position, the roller assembly 420 can tension the pulled-out film to prevent it from becoming loose. The second clamping jaw assembly 430 grabs the film of the film roll 90 and continues to extend it for a distance along the first direction. In this way, a fixed-length film 90c is formed between the first clamping jaw assembly 410 and the second clamping jaw assembly 430. The cutting assembly 440 cuts the fixed-length film 90c to separate the fixed-length film 90c from the film roll 90. The gluing mechanism 500 grabs the fixed-length film 90c and transfers it to the corresponding workstation for adhesion with the battery, thereby completing the automatic gluing process.

[0119] In some possible embodiments, referring to FIG. 9 to FIG. 14 , the first clamping jaw assembly 410 includes a fourth guide rail 411 , a seventh driver 412 , and a first clamping jaw 413 .

[0120] Along the first direction, the fourth guide rail 411 includes a fifth working position at one end and a sixth working position at the other end. Referring to Figures 12 to 14 , the fifth working position is the left end of the fourth guide rail 411 away from the second clamping jaw assembly 430, and the sixth working position is the right end of the fourth guide rail 411 close to the second clamping jaw assembly 430.

[0121] The first clamping jaw 413 is movably arranged on the fourth guide rail 411; the seventh driver 412 is transmission-connected to the first clamping jaw 413, and the seventh driver 412 is used to drive the first clamping jaw 413 to switch between the fifth working position and the sixth working position.

[0122] The fifth and sixth working positions are located at the two ends of the roller assembly 420 along the first direction, respectively. As shown in FIG12 , when the first clamping jaw 413 is in the fifth working position, the first clamping jaw 413 is able to grasp the rubber head 91 of the film 90 on the film spool 310. Furthermore, as shown in FIG13 , driven by the seventh driver 412 , the first clamping jaw 413 switches from the fifth working position to the sixth working position. The first clamping jaw 413 is able to pull the rubber head 91 of the film 90 from the fifth working position through the roller assembly 420 to the sixth working position, thereby automatically threading the film 90 through the roller assembly 420, eliminating the need for manual threading and effectively saving manpower.

[0123] In some embodiments, the seventh driver 412 may be a servo motor or a motor.

[0124] In some possible embodiments, referring to FIG. 9 to FIG. 14 , the second clamping jaw assembly 430 includes a fifth guide rail 431 , an eighth driver 432 , and a second clamping jaw 433 .

[0125] Along the first direction, the fifth guide rail 431 includes a seventh working position at one end and an eighth working position at the other end; wherein, in combination with the orientations shown in Figures 12 to 14, the seventh working position is close to the left end of the first clamping jaw 413, and the eighth working position is away from the right end of the first clamping jaw 413.

[0126] The second clamping jaw 433 is movably disposed on the fifth guide rail 431, and the eighth driver 432 is in transmission connection with the second clamping jaw 433. The eighth driver 432 is used to drive the second clamping jaw 433 to switch between the seventh working position and the eighth working position.

[0127] Specifically, as shown in FIG13 , the first clamping jaw 413 pulls the film of the film roll 90 from the fifth working position through the roller assembly 420 to the sixth working position, and the second clamping jaw 433 is in the seventh working position. The second clamping jaw 433 can grab the film of the film roll 90 from the first clamping jaw 413; and as shown in FIG14 , under the drive of the eighth driver 432, the second clamping jaw 433 moves from the seventh working position to the eighth working position on the right side; during the movement, the first clamping jaw 413 is slightly loosened, so that the second clamping jaw 433 can continue to grab the film of the film roll 90. It extends a distance to the right along the first direction, and finally the first clamping jaw 413 and the second clamping jaw 433 jointly clamp the film of the film roll 90, so that a fixed-length film 90c is formed between the first clamping jaw 413 and the second clamping jaw 433; the fixed-length film 90c is adsorbed by the gluing mechanism 500, and the cutting component 440 cuts the fixed-length film 90c, so that the fixed-length film 90c is separated from the film roll 90, and the gluing mechanism 500 transfers the adsorbed fixed-length film 90c and sticks it to the battery, thereby completing the process of automatic threading and automatic gluing, effectively saving manpower.

[0128] In some possible embodiments, referring to FIG. 9 to FIG. 14 , the roller assembly 420 includes a plurality of rollers 421 and a ninth driver 422 .

[0129] The plurality of rollers 421 are arranged at intervals along the first direction. Usually, two adjacent rollers 421 are distributed along the third direction on the upper and lower sides of the horizontal plane where the film of the film roll 90 is located. The ninth driver 422 is used to drive the rollers 421 to rise or fall along the third direction.

[0130] As shown in FIG12 , the first clamping jaw 413 is in the fifth working position. The first clamping jaw 413 can grab the film 90 on the film spool 310. The multiple rollers 421 located on the upper and lower sides of the horizontal plane are kept retracted under the action of the ninth driver 422, that is, the rollers 421 are away from the film 90. As shown in FIG13 , under the drive of the seventh driver 412, the first clamping jaw 413 switches from the fifth working position to the sixth working position. The first clamping jaw 413 can pull the rubber head 91 of the film 90 from the fifth working position through the roller assembly 420 to the sixth working position. The second clamping jaw 433 can be moved from the fifth working position to the sixth working position. The first clamp 413 grabs the film of the film roll 90, and the multiple rollers 421 located on the upper side of the horizontal plane are vertically lowered for a distance under the action of the ninth driver 422, and the multiple rollers 421 located on the lower side of the horizontal plane are vertically raised for a distance under the action of the ninth driver 422, forming a form as shown in Figure 14. The multiple rollers 421 are used to tension the film of the film roll 90, so that when the second clamp 433 grabs the film of the film roll 90 and extends it to the right along the first direction, the film of the film roll 90 is always kept in a tensioned state, avoiding wrinkles after the cutting component 440 cuts the fixed-length film 90c.

[0131] In some embodiments, the ninth driver 422 may be a cylinder or a motor.

[0132] In some embodiments, referring to FIG. 9 to FIG. 14 , the cutting assembly 440 includes a cutting blade 441 and a tenth driver 442 .

[0133] The cutter 441 may be a blade or a cutting tool, and the tenth driver 442 may be a transverse cylinder or a motor.

[0134] Along the first direction, the cutting blade 441 is disposed between the second clamping jaw 433 and the first clamping jaw 413 ; the tenth driver 442 is used to drive the cutting blade 441 to reciprocate horizontally along the second direction.

[0135] As shown in Figure 14, a fixed-length film 90c is formed between the first clamping jaw 413 and the second clamping jaw 433; the fixed-length film 90c is adsorbed by the gluing mechanism 500, and the tenth driver 442 drives the cutting knife 441 to cut the fixed-length film 90c along the second direction, so that the fixed-length film 90c is separated from the film 90.

[0136] It should be understood that after the first clamp 413 grabs the glue head 91 of the film and moves to the sixth working position, it usually remains stationary; the second clamp 433 continuously switches between the seventh working position and the eighth working position, thereby continuously pulling out the fixed-length film 90c, and then the gluing mechanism 500 adsorbs the fixed-length film 90c, and the cutting component 440 cuts the fixed-length film 90c, realizing the automatic gluing process.

[0137] In the above process, the cutting knife 441 is usually located closer to the first clamping jaw 413, but there is still a distance between the incision of the cutting knife 441 and the first clamping jaw 413. In this way, when the fixed-length film 90c is cut, a section of the film roll 90 will still remain on the first clamping jaw 413 as a new glue head to facilitate the second clamping jaw 433 to re-grab it, and repeat the actions between Figures 13 and 14.

[0138] When the film 90 on the film spool 310 has been consumed, the film spool 310 can rotate in the opposite direction. As shown in Figures 13 and 14, the film spool 310 is used to roll the remaining film extending from the circumference of the film 90 to the right to the first clamping claw 413 to form an empty reel 90b, effectively avoiding the situation where the film falls off and causes downtime. As shown in Figure 8, the used empty reel 90b is removed from the film spool 310 by the shifting mechanism 200, and the film 90 to be used is transferred from the glue preparation mechanism 100 to the film spool 310 again, so that the next round of production process can be automatically started, which not only realizes the fully automatic glue bonding process of the battery with high efficiency and controllable and stable quality, but also realizes the automatic loading of the film 90 and the automatic unloading of the empty reel 90b, saving manpower and reducing production costs.

[0139] In each embodiment of the present application, the first direction and the second direction may be two intersecting directions in a horizontal plane, and the third direction may be a vertical direction perpendicular to the first direction and the second direction.

[0140] In some possible embodiments, referring to Figures 1, 2, and 11 to 14, the adhesive laminating mechanism 500 includes a driving unit 510, an action arm 520, and a negative pressure suction cup 530. The negative pressure suction cup 530 is disposed at the end of the action arm 520, and the driving unit 510 drives the action arm 520 to move up and down.

[0141] Among them, the driving unit 510 can be a servo motor or a cylinder. Under the drive of the driving unit 510, the action arm 520 can realize the lifting action; the negative pressure suction cup 530 is set at the end of the action arm 520. When the fixed-length film 90c is formed between the first clamping jaw 413 and the second clamping jaw 433, the driving unit 510 drives the action arm 520 to descend, driving the negative pressure suction cup 530 to descend until it contacts the fixed-length film 90c and realizes negative pressure adsorption; the component to be cut 440 cuts the fixed-length film 90c, and the fixed-length film 90c is separated from the film roll 90; the driving unit 510 drives the action arm 520 to rise, thereby transferring the fixed-length film 90c, and completing the corresponding adhesion of the fixed-length film 90c to the battery.

[0142] In some embodiments, the adhesive bonding mechanism 500 includes two sets of spaced-apart action arms 520. These two sets of action arms 520 can be attached to the ends of the fixed-length adhesive sheet 90c, facilitating bonding to the battery. The spacing between the two sets of spaced-apart action arms 520 can be fixed or adjustable, allowing the action arms 520 to adjust to the varying lengths of the fixed-length adhesive sheet 90c, facilitating bonding.

[0143] A second aspect of the present application provides a battery production line, comprising the above-mentioned glue laminating equipment.

[0144] A third aspect of the present application is an automatic glue laminating method, which is applied to the above-mentioned glue laminating equipment.

[0145] 1 to 15 , the automatic glue application method includes:

[0146] S10: Confirm that the film 90 on the film spool 310 has been consumed to a predetermined extent. The controller (not shown) of the gluing device can sense the outer diameter of the film 90 on the film spool 310 via the second sensor 370 disposed on the support portion 320. Thus, as the film 90 rotates forward to output film, the outer diameter of the film 90 decreases as the film is continuously output. When the outer diameter of the film 90 decreases to a predetermined value, such as 100 mm, 90 mm, or another configurable value, the second sensor 370 senses the outer diameter of the film 90 and sends a corresponding signal. Upon receiving the signal, the controller determines that the film 90 on the film spool 310 has been consumed to a predetermined extent and that a new film 90 needs to be replaced.

[0147] In addition, in addition to sensing the outer diameter, the second sensor 370 can also sense the weight of the film 90. As long as the controller of the gluing device can confirm under certain conditions that the film 90 on the film spool 310 has been consumed to a preset level and needs to be replaced with a new film 90, the specific design shall prevail.

[0148] S20, controlling the film reel 310 to rotate in the reverse direction, so that the film 90 on the film reel 310 winds the remaining film on the outside in the reverse direction to form an empty reel 90b.

[0149] S30, control the shift mechanism 200 to remove the empty roll 90b from the film shaft 310. Specifically, the controller of the gluing device controls the shift mechanism 200 to move the empty roll 90b from the film shaft 310 to the empty film chamber 140, so as to facilitate centralized processing of the empty rolls 90b.

[0150] S40 , controlling the shifting mechanism 200 to transfer the film 90 stored in the glue preparation mechanism 100 to the film reel 310 of the glue dispensing mechanism 300 .

[0151] By executing steps S20-S40 and coordinating the actions of various components, the automatic winding of the gluing equipment can be achieved, and manual intervention caused by the remaining film on the film 90 falling off can be avoided, so that the shifting mechanism 200 can automatically remove the empty reel 90b from the film shaft 310; in this way, there is no need for operators to stop the machine, which improves the production efficiency of the gluing equipment; the controller of the gluing equipment controls the bidirectional rotation of the film shaft 310 and cooperates with the shifting mechanism 200 to complete the automatic loading of the film 90 and the automatic unloading of the empty reel 90b, without the need for manual reverse rotation of the film 90 and manual removal of the empty reel 90b, effectively saving manpower.

[0152] In some possible embodiments, referring to FIG. 1 to FIG. 15 , after step S40 , the automatic glue application method further includes:

[0153] S50: Control the film spool 310 to rotate forward until the adhesive head 91 of the film 90 is aligned with the adhesive drawing mechanism 400. The controller of the adhesive laminating device controls the film spool 310 to rotate forward, thereby driving the film 90 to rotate forward. When the film 90 rotates to a certain angle, the adhesive head 91 is aligned with the adhesive drawing mechanism 400, thereby facilitating the adhesive drawing mechanism 400 to grasp the adhesive head 91. The angle can also be determined by a sensor that senses the angle and sends a signal back to the controller, which will not be further described here.

[0154] S60: Control the glue pulling mechanism 400 to grab the glue head 91 and pull out the film, and then cut it to a fixed length to form a fixed-length film 90c. The controller of the glue laminating device controls the glue pulling mechanism 400 to pull the glue head 91 outward in a first direction. The film spool 310 rotates in conjunction with the glue pulling mechanism 400, thereby driving the film 90 to continuously rotate forward and release a continuous film. In this way, the glue pulling mechanism 400 can cut the film 90 on the film spool 310 into fixed-length films 90c.

[0155] S70: Control the gluing mechanism 500 to grab the fixed-length film 90c for gluing. The controller of the gluing device controls the drive unit 510 to drive the action arm 520 up and down. The negative pressure suction cup 530, which cuts off the ink of the action arm 520, suctions the fixed-length film 90c under negative pressure. The drive unit 510 drives the action arm 520 up, thereby transferring the fixed-length film 90c and completing the corresponding gluing between the fixed-length film 90c and the battery. The entire process does not require operator intervention, thereby improving the production efficiency of the gluing device.

[0156] In this way, in steps S10-S70, through the mutual cooperation of various components and the bidirectional rotation of the film shaft 310, not only is the fully automatic gluing process of the battery realized with high efficiency and controllable and stable quality, and the situation of film falling off causing downtime is effectively avoided, but also the automatic loading of the film 90 and the automatic unloading of the empty roll 90b are realized, which saves manpower and reduces production costs.

[0157] In some possible embodiments, referring to FIG. 1 to FIG. 16 , the glue pulling mechanism 400 includes a first clamping jaw assembly 410 , a roller assembly 420 , a cutting assembly 440 , and a second clamping jaw assembly 430 .

[0158] The S60 steps specifically include:

[0159] S61: Control the first clamping jaw assembly 410 to grab the adhesive head 91. The controller of the adhesive laminating device controls the film reel 310 to rotate forward; when it rotates to a certain angle, the adhesive head 91 is aligned with the first clamping jaw assembly 410, thereby facilitating the first clamping jaw assembly 410 to grab the adhesive head 91.

[0160] S62: Control the first clamping jaw assembly 410 to drive the adhesive head 91 through the roller assembly 420 in a first direction. The controller of the adhesive laminating device controls the first clamping jaw 413 of the first clamping jaw assembly 410 to pull the film of the film roll 90 from one end position through the roller assembly 420 to the other end position; thereby automatically threading the film roll 90, avoiding the manual threading process and effectively saving manpower.

[0161] S63 : Control the second clamping jaw assembly 430 to grab the adhesive head 91 on the first clamping jaw assembly 410 . The controller of the adhesive laminating device controls the second clamping jaw 433 of the second clamping jaw assembly 430 to grab the film of the film roll 90 from the first clamping jaw 413 .

[0162] S64: Control the roller assembly 420 to tension the film on the film roll 90. The controller of the gluing device controls the ninth driver 422 of the roller assembly 420 to rise or fall in the third direction, thereby causing the multiple rollers 421 of the roller assembly 420 to tension the film on the film roll 90, ensuring that the film on the film roll 90 remains tensioned, thereby preventing wrinkles from forming after the cut-to-length film 90c is cut by the cutting assembly 440.

[0163] S65: Control the second clamping assembly 430 to move so as to form a fixed-length film sheet 90c between the second clamping assembly 430 and the first clamping assembly 410. The controller of the adhesive laminating apparatus controls the eighth driver 432 to drive the second clamping jaw 433 of the second clamping assembly 430 to move the film roll 90 a certain distance in the first direction, thereby forming the fixed-length film sheet 90c between the first clamping jaw 413 and the second clamping jaw 433.

[0164] S66: Control the cutting assembly 440 to cut the fixed-length film 90c. The gluing mechanism 500 absorbs the fixed-length film 90c, and the cutting assembly 440 cuts the fixed-length film 90c, separating the fixed-length film 90c from the film roll 90. The gluing mechanism 500 transfers the absorbed fixed-length film 90c and attaches it to the battery, thereby completing the automatic threading and gluing process, effectively saving manpower.
