[0058] At present, from the perspective of market development, the application of power batteries is becoming more and more extensive. Power batteries are not only used in energy storage power systems such as hydropower, thermal power, wind power and solar power stations, but also widely used in electric vehicles such as electric bicycles, electric motorcycles, electric cars, as well as aerospace and other fields. With the continuous expansion of the application field of power batteries, the market demand is also constantly expanding.

[0059] During the production of batteries, it is often necessary to use glue sticking equipment to stick the film on the battery cell. Since the glue sticking equipment relies on the clamping claws to pull the film on the film roll, the film cannot be pulled out completely, otherwise the film will be separated from the roller in the center of the film roll, causing the equipment to become chaotic. In the related art, when the film on the film roll is almost used up, it is often necessary to manually rotate the film roll in the opposite direction to collect the remaining film to form an empty roll, and then manually remove the empty roll and replace it with a new film, which is not only complicated to operate, but also wastes manpower.

[0060] A first aspect of the present application provides a glue sticking device, which is applied to a glue roll 90 to perform a corresponding glue sticking process on a battery cell.

[0061] See also Figures 1 to 8 As shown, Figure 1 A schematic diagram of the structure of a glue sticking device provided in some embodiments of the present application; Figure 2 A schematic structural diagram of a glue laminating device from another perspective provided in some embodiments of the present application; Figure 3 A schematic diagram of the assembly of the glue preparation mechanism and the film roll provided in some embodiments of the present application; Figure 4 A schematic diagram of the assembly of a shifting mechanism and a film provided in some embodiments of the present application; Figure 5 A schematic diagram of the structure of a shifting mechanism provided in some embodiments of the present application; Figure 6 A schematic diagram of the assembly of a film dispensing mechanism and a film roll provided in some embodiments of the present application; Figure 7 for Figure 6 A schematic diagram of the structure shown in another viewing angle; Figure 8 Schematic diagram of the positional relationship of the glue preparation mechanism, the shifting mechanism and the glue placing mechanism provided in some embodiments of the present application. The glue application device comprises: a glue preparation mechanism 100, a shifting mechanism 200 and a glue placing mechanism 300.

[0062] The glue preparation mechanism 100 is used to store the film 90 to be used; the glue dispensing mechanism 300 includes at least one bidirectionally rotatable film reel 310. The shifting mechanism 200 is movably arranged between the glue preparation mechanism 100 and the shifting mechanism 200. The shifting mechanism 200 can transfer the film 90 from the glue preparation mechanism 100 to the film reel 310; the film reel 310 rotates forward, and the film 90 on the film reel 310 outputs the film, and cooperates with the corresponding glue pulling mechanism 400 (mentioned below) to pull out the film for cutting.

[0063] When the film 90 on the film spool 310 has been consumed to a preset extent, the film spool 310 rotates in the opposite direction, and the film 90 on the film spool 310 reversely rolls the remaining film on the outside to form an empty roll 90b; in this way, automatic winding can be achieved, avoiding the remaining film of the film 90 from falling off and causing manual intervention, so that the shifting mechanism 200 can automatically remove the empty roll 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 glue sticking equipment; through the two-way rotation of the film spool 310 and in conjunction with the shifting mechanism 200, the automatic loading of the film 90 and the automatic unloading of the empty roll 90b are completed, without the need for manual reverse rotation of the film 90 and manual removal of the empty roll 90b, which effectively saves manpower.

[0064] It should be understood that positive rotation and reverse rotation are relative concepts. For example, the positive rotation of the film shaft 310 may be clockwise rotation, and the film 90 may release the film as the film shaft 310 rotates forward, while the reverse rotation of the film shaft 310 is counterclockwise rotation, and the film 90 may reel in the remaining film as the film shaft 310 rotates reversely to form an empty roll 90b; accordingly, the positive rotation of the film shaft 310 may be counterclockwise rotation, and the positive rotation of the film shaft 310 is clockwise rotation, which is subject to the design.

[0065] For ease of description, in the following embodiments, the film spool 310 drives the film 90 to rotate clockwise as a positive rotation, and the film 90 releases the film outward, and the film spool 310 drives the film 90 to rotate counterclockwise as a reverse rotation, and the film 90 reversely winds the remaining film outside.

[0066] 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 with the film of this distance as the remaining film outside to avoid the film of this section from being entangled in the glue sticking equipment and affecting the use of the equipment.

[0067] Optionally, the film shaft 310 is an inflatable shaft. The film shaft 310 can be inflated to expand and maintain a larger diameter, so that the film 90 can be fixed on the film shaft 310 and rotated forward or reversely. When the film shaft 310 needs to be replaced with a new film 90, the film shaft 310 can be deflated and the volume can be reduced. The diameter of the film shaft 310 is smaller than the mounting hole (not marked) in the middle of the film 90. The film shaft 310 and the film 90 are no longer relatively fixed, and the film 90 / empty roll 90b can be smoothly taken out or put in from the film shaft 310, which facilitates the shift mechanism 200 to complete the automatic loading of the film 90 and the automatic unloading of the empty roll 90b.

[0068] In some possible embodiments, see Figures 9 to 11 As shown, Fig. 9 A schematic diagram of the structure of the glue pulling mechanism provided in some embodiments of the present application; Fig.10 A top view of a glue pulling mechanism provided in some embodiments of the present application; Fig.11 The structural diagram of the glue sticking mechanism provided in some embodiments of the present application. The glue sticking device includes a glue pulling mechanism 400 and a glue sticking mechanism 500.

[0069] The film 90 has a rubber head 91 protruding radially. The rubber pulling mechanism 400 can grab the rubber head 91 of the film 90 on the film reel 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.

[0070] 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 of the film roll itself, or it can be formed by connecting a customized card with the film of the film roll 90, depending on the specific design.

[0071] Specifically, the film reel 310 can drive the film 90 to rotate in the forward direction. When it rotates to a certain angle, the rubber head 91 is aligned with the rubber pulling mechanism 400; thus, it is convenient for the rubber pulling mechanism 400 to grab the rubber head 91. The rubber pulling mechanism 400 pulls the rubber head 91 outward, and the film reel 310 cooperates with the rubber pulling mechanism 400, thereby driving the film 90 to rotate in the forward direction continuously to release continuous films. The glue pulling mechanism 400 can cut the film 90 on the film reel 310 into fixed-length films 90c, and the glue sticking mechanism 500 can grab the fixed-length films 90c for sticking; 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.

[0072] 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 sticking mechanism 500, the forward and reverse rotation of the film reel 310 is utilized; not only the fully automatic glue sticking process of the battery is realized with high efficiency, controllable and stable quality, and the shutdown caused by film falling off 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.

[0073] In some possible embodiments, see Figures 1 to 3 ,as well as Figure 8 As shown, the glue preparation mechanism 100 includes at least one material shaft 110. The material shaft 110 is used to store the film 90 to be used; according to design requirements, the glue preparation mechanism 100 can store one or more films 90, and are arranged in series on the material shaft 110, so that the shift mechanism 200 can use them conveniently.

[0074] The film reel 310 and the material reel 110 are spaced apart from each other and are coaxially arranged; the shifting mechanism 200 is at least partially movably arranged between the film reel 310 and the material reel 110. In this way, the shifting mechanism 200 can transfer the film 90 from the film preparation mechanism 100 to the film reel 310 by linear motion without the need for corresponding lifting or turning, which is conducive to the simplification of the structure.

[0075] Optionally, the material shaft 110 is an inflatable shaft. The material shaft 110 can be inflated to expand and maintain a larger diameter, so that the film 90 can be easily fixed on the material shaft 110. When the film shaft 310 needs to be replaced with a new film 90, the material shaft 110 can be deflated and reduced in size. The diameter of the material shaft 110 is smaller than the mounting hole in the middle of the film 90, and the material shaft 110 and the film 90 are no longer relatively fixed. The shifting mechanism 200 can smoothly take the film 90 to be used from the material shaft 110 and transfer it to the film shaft 310, thereby completing the automatic loading process of the film 90.

[0076] In some possible embodiments, see Figures 1 to 3 ,as well as Figure 8 As shown, the glue preparation mechanism 100 includes a first guide rail 120, a mounting portion 130 and a first driver (not shown);

[0077] The mounting portion 130 can be a plate or a frame, and can be made of metal such as carbon steel or stainless steel. The material shaft 110 is mounted on the mounting portion 130, and the mounting portion 130 is movably arranged on the first guide rail 120, and the first driver is in transmission connection with the mounting portion 130. The first driver is used to drive the mounting portion 130 to move along the first guide rail 120. In this way, the first driver can drive the mounting portion 130 to adjust the position, so as to stagger the material shaft 110 and the film shaft 310, so that the operator can conveniently put the film 90 to be used on the material shaft 110, and then drive the mounting portion 130 to adjust the position by the first driver, so as to restore the material shaft 110 and the film shaft 310 to be coaxial, so as to realize automatic loading of the shifting mechanism 200.

[0078] Optionally, the first driver may be a cylinder or a motor.

[0079] In some possible embodiments, see Figures 1 to 3 ,as well as Figure 8 As shown, the film preparation mechanism 100 includes an empty film roll compartment 140, a second guide rail 150 and a second driver (not shown).

[0080] The empty film chamber 140 is a slot structure with an opening at the top, and is used to store the empty roll 90b removed from the film shaft 310. Specifically, the empty film chamber 140 is located below the area between the film shaft 310 and the material shaft 110; when the film 90 on the film shaft 310 has been consumed to a preset degree, the shifting mechanism 200 can remove the empty roll 90b on the film shaft 310 from the film shaft 310, and release the corresponding fixed clamp at a predetermined position, so that the empty roll 90b falls into the empty film chamber 140 below, which is convenient for the operator to clean up. The shifting mechanism 200 then transfers the film 90 to be used from the film preparation mechanism 100 to the film shaft 310. The entire process is fully automated, without manual intervention, and the film 90 can be replaced without stopping the machine.

[0081] The empty film chamber 140 is movably arranged on the second guide rail 150; the second driver is in transmission connection with the empty film chamber 140. The second driver is used to drive the empty film chamber 140 to move along the second guide rail 150, and the operator pulls the empty film chamber 140 out from below the area between the film shaft 310 and the material shaft 110, so as to conveniently clean the empty film rolls 90b therein.

[0082] Optionally, the second driver may be a cylinder or a motor.

[0083] In some possible embodiments, see Figure 1 , Figure 2 , Figure 4 , Figure 5 as well as Figure 8 As shown, the shifting mechanism 200 includes a third guide rail 210 , a clamping module 220 and a sixth driver 230 .

[0084] The third guide rail 210 is installed between the film reel 310 and the glue preparation mechanism 100; the extension direction of the third guide rail 210 is generally parallel to the axial direction of the material reel 110. The third guide rail 210 includes a first working position at one end thereof and a second working position at the other end thereof, wherein the first working position is an end of the third guide rail 210 close to the glue preparation mechanism 100, and the second working position is an opposite end of the third guide rail 210 close to the glue placement mechanism 300.

[0085] The clamping module 220 is movably disposed on the third guide rail 210 , and the sixth driver 230 is transmission-connected to 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.

[0086] Specifically, when the sixth driver 230 drives the clamping module 220 to reach the first working position on the right side, 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.

[0087] Combination Figure 8 In the position shown, when the film 90 on the film reel 310 has been consumed to a preset level, the clamping module 220 moves leftward to the second working position, removes the empty roll 90b on the film reel 310 from the film reel 310, and drops the empty roll 90b into the empty film chamber 140 below at a predetermined position. Finally, the clamping module 220 moves rightward to the first working position again to clamp the film 90 to be used from the material reel 110 of the glue preparation mechanism 100.

[0088] 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.

[0089] Optionally, the sixth driver 230 may be a stepper motor, a servo motor or a cylinder.

[0090] In some possible embodiments, see Figure 1 , Figure 2 , Figure 4 , Figure 5 as well as Figure 8 As shown; the clamping module 220 includes a base 221, at least two clamping jaws 222 arranged opposite to each other and a third driver 223.

[0091] The base 221 is movably disposed on the third guide rail 210 , all the clamping jaws 222 are movably disposed on the base 221 , and the third driver 223 is used to drive the clamping jaws 222 to move closer to or away from each other.

[0092] The third driver 223 may be a cylinder, the cylinder body of which is fixed on the base 221, and the clamping claw 222 is fixed on the end of the movable rod of the third driver 223. Figure 4 The movable rod is extended and retracted by ventilating from different air inlet positions of the cylinder, so that the clamping jaws 222 are moved closer or farther away from each other. A third driver 223 drives all the clamping jaws 222 to move closer or farther away from each other. Alternatively, two or more third drivers 223 can respectively drive one clamping jaw 222 to move closer or farther away from each other.

[0093] 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.

[0094] In some possible embodiments, see Figure 4 As shown, 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 glue preparation mechanism 100 .

[0095] The first sensor 240 may be a position sensor or a photoelectric sensor.

[0096] 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 clamp 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.

[0097] In some possible embodiments, see Figure 1 , Figure 2 ,as well as Figures 6 to 8 As shown, the glue placing mechanism 300 includes a supporting portion 320 and a fourth driver 330 .

[0098] The support part 320 can be a plate or a frame, and can be made of metal such as carbon steel, stainless steel, etc. One end of the film shaft 310 is rotatably disposed on the support part 320 ; the other end of the film shaft 310 protrudes axially from the support part 320 for carrying the film 90 .

[0099] The fourth driver 330 is fixed on the support part 320 and is in driving connection with the film reel 310. The fourth driver 330 drives the film reel 310 to rotate forward or reversely, thereby realizing the automatic winding of the empty reel 90b, effectively avoiding the situation of film falling off and causing downtime, and then realizing the automatic loading of the film 90 and the automatic unloading of the empty reel 90b, saving manpower and reducing production costs.

[0100] Optionally, the fourth driver 330 may be a motor.

[0101] In some embodiments, see Figure 1 , Figure 2 ,as well as Figures 6 to 8 As shown, the glue releasing mechanism 300 includes a push plate assembly and a fifth driver 360; the fifth driver 360 is in driving connection with the push plate assembly, and the push plate assembly can push the empty roll 90b on the film shaft 310 out in the axial direction.

[0102] The push plate assembly may include a fixing seat 340 , a push plate 350 , and a sixth guide rail 341 .

[0103] The sixth guide rail 341 is disposed on the fixing seat 340, and the support portion 320 is movably disposed on the sixth guide rail 341. The extension direction of the sixth guide rail 341 may be parallel to the axial direction of the film reel 310. The sixth guide rail 341 includes a third working position at one end and a fourth working position at the other end.

[0104] The fifth driver 360 is in transmission connection with the support part 320; the fifth driver 360 is used to drive the support part 320 to switch between the third working position and the fourth working position. The push plate 350 is fixedly connected with the fixing seat 340, and the push plate 350 is located on the peripheral side of the film shaft 310; when the support part 320 is in the fourth working position, the push plate 350 can push out the film 90 / empty roll 90b on the film shaft 310.

[0105] Combination Figure 7 In the shown position, the current support portion 320 is in the fifth working position, and the film reel 310 can rotate in the positive direction so that the film 90 outputs the film, and cooperates with the corresponding film pulling mechanism 400 to pull out the film for cutting. When the film 90 on the film reel 310 has been consumed to a preset extent, the film reel 310 rotates in the reverse direction, and the film 90 on the film reel 310 reversely rolls the remaining film on the outside 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 reel 310 to move to the lower left, so that the empty reel 90b on the film reel 310 conflicts with the push plate 350; the film reel 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 reel 310 and is grasped and taken out by the clamp 222, which facilitates the shifting mechanism 200 to complete the automatic unloading of the empty reel 90b.

[0106] Optionally, the fifth driver 360 may be a motor or a cylinder.

[0107] In some possible embodiments, see Figure 6 and Figure 7 As shown, the glue dispensing mechanism 300 includes a second sensor 370 disposed on the support portion 320. The second sensor 370 can be a beam-type optical fiber, a photoelectric sensor, or a position sensor.

[0108] The second sensor 370 is used to sense the outer diameter of the film 90 on the film reel 310. In this way, the second sensor 370 can timely sense the extent of the film 90 consumption on the film reel 310. When the film 90 rotates forward, the output film is cut to a fixed length and then pasted, and 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 that the film reel 310 is full. The film 90 on 0 has been consumed to a preset extent and needs to be replaced with a new film 90; at this time, the film reel 310 is controlled to rotate in the opposite direction, and the film 90 on the film reel 310 reversely rolls the remaining film on the outside to form an empty reel 90b, thereby realizing automatic winding, avoiding the film remaining on the film 90 from falling off and causing manual intervention, and then enabling the shifting mechanism 200 to remove the empty reel 90b from the film reel 310, and cooperate with the shifting mechanism 200 to complete the automatic unloading of the empty reel 90b, without the need to manually monitor the use of the film 90, effectively saving manpower.

[0109] In some possible embodiments, see Figure 6 and Figure 7 As shown, the glue dispensing mechanism 300 includes a third sensor 380 disposed on the support portion 320. The third sensor 380 can be an angle sensor, a CCD camera, and the like.

[0110] The third sensor 380 is used to identify the rotation angle of the film 90 on the film reel 310. The film reel 310 can drive the film 90 to rotate in the positive direction. When the film 90 rotates to a certain angle, the third sensor 380 can identify the edge on the side of the glue head 91 of the film 90 to determine the angle position of the glue head 91 itself; in this way, the glue head 91 can be aligned with the glue pulling mechanism 400; in this way, it is convenient for the glue pulling mechanism 400 to grab the glue head 91.

[0111] Optionally, see Figure 6 and Figure 7 As shown, the glue dispensing mechanism 300 includes a fourth sensor 390 disposed on the support portion 320, and the fourth sensor 390 can be a photoelectric sensor, a CCD camera, etc. The third sensor 380 can identify whether the film 90 on the film reel 310 is placed upside down by color, and send out a corresponding alarm signal to ensure the normal operation of the glue dispensing device.

[0112] In some possible embodiments, see Figure 1 , Figure 2 , Figures 9 to 14 As shown, Figure 12 to Figure 14The schematic diagram of the positional relationship of the glue placing mechanism, the glue pulling mechanism and the glue sticking mechanism provided in some embodiments of the present application. 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 .

[0113] The first clamping jaw assembly 410 can grab the rubber head 91 and drive the film of the film roll 90 to pass through the roller assembly 420 in a first direction. The first direction is usually one of the directions in the horizontal plane and intersects with the axial direction of the film shaft 310.

[0114] The roller assembly 420 is used to tension the film of the film roll 90; the second clamping jaw assembly 430 can grab the rubber head 91 from the first clamping jaw assembly 410 and form a fixed-length film 90c between the second clamping jaw assembly 430 and the first clamping jaw assembly 410, and the cutting assembly 440 is used to cut and form the fixed-length film 90c.

[0115] Specifically, the film shaft 310 rotates forward under the drive of the fourth driver 330; when it rotates to a certain angle, the rubber head 91 is aligned with the rubber pulling mechanism 400, so that the first clamping jaw assembly 410 can grab the rubber head 91. The first clamping jaw assembly 410 drives the film of the film 90 to pass through the roller assembly 420 in the first direction, and the film shaft 310 cooperates with the first clamping jaw assembly 410, thereby driving the film 90 to rotate forward continuously to release 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 loosening. 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.

[0116] In some possible embodiments, see Figures 9 to 14 As shown, the first clamping jaw assembly 410 includes a fourth guide rail 411 , a seventh driver 412 , and a first clamping jaw 413 .

[0117] 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. Figure 12 to Figure 14 The fifth working position is when the fourth guide rail 411 is away from the left end of the second clamping jaw assembly 430, and the sixth working position is when the fourth guide rail 411 is close to the right end of the second clamping jaw assembly 430.

[0118] The first clamping jaw 413 is movably disposed 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.

[0119] The fifth working position and the sixth working position are respectively located at two ends of the roller assembly 420 along the first direction; Fig.12 As shown, when the first clamping jaw 413 is in the fifth working position, the first clamping jaw 413 can grab the glue head 91 of the film 90 on the film reel 310. Fig.13 As shown, under the drive of the seventh driver 412, the first clamp 413 switches from the fifth working position to the sixth working position, and the first clamp 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, thereby completing the automatic passage of the film 90 through the roller assembly 420, avoiding the manual threading process and effectively saving manpower.

[0120] Optionally, the seventh driver 412 may be a servo motor or a motor.

[0121] In some possible embodiments, see Figures 9 to 14 As shown, the second clamping jaw assembly 430 includes a fifth guide rail 431 , an eighth driver 432 , and a second clamping jaw 433 .

[0122] 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; Figure 12 to Figure 14 In the orientation shown, 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 .

[0123] The second clamping jaw 433 is movably disposed on the fifth guide rail 431, and the eighth driver 432 is transmission-connected 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.

[0124] Specifically, combined Fig.13 As shown, 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, and the second clamping jaw 433 can grab the film of the film roll 90 from the first clamping jaw 413; Fig.14As shown, driven by the eighth driver 432, the second clamp 433 moves from the seventh working position to the eighth working position on the right; during the movement, the first clamp 413 is slightly loosened, so that the second clamp 433 can continue to grab the film of the film roll 90 and extend a distance to the right along the first direction. Finally, the first clamp 413 and the second clamp 433 clamp the film of the film roll 90 together, so that a fixed-length film 90c is formed between the first clamp 413 and the second clamp 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, which effectively saves manpower.

[0125] In some possible embodiments, see Figures 9 to 14 As shown, the roller assembly 420 includes a plurality of rollers 421 and a ninth driver 422 .

[0126] The plurality of rollers 421 are arranged at intervals along the first direction. Usually, two adjacent rollers 421 are distributed along the third direction at 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.

[0127] Combination Fig.12 As shown, the first clamping jaw 413 is in the fifth working position, and the first clamping jaw 413 can grab the film of the film roll 90 on the film reel 310, and the plurality of rollers 421 located on the upper and lower sides of the horizontal plane are kept contracted under the action of the ninth driver 422, that is, the rollers 421 are away from the film of the film roll 90; Fig.13 As shown, under the drive of the seventh driver 412, the first clamp 413 switches from the fifth working position to the sixth working position, the first clamp 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 clamp 433 can grab the film of the film 90 from the first clamp 413, 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 as shown in FIG. Fig.14 In the form shown, 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 always remains in a tensioned state, avoiding wrinkles after the cutting component 440 cuts the fixed-length film 90c.

[0128] Optionally, the ninth driver 422 may be a cylinder or a motor.

[0129] In some embodiments, see Figures 9 to 14As shown, the cutting assembly 440 includes a cutting blade 441 and a tenth driver 442 .

[0130] The cutting blade 441 may be a blade or a cutting tool, and the tenth driver 442 may be a traverse cylinder or a motor.

[0131] Along the first direction, the cutting knife 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 knife 441 to reciprocate horizontally along the second direction.

[0132] Combination Fig.14 As shown, a fixed-length film 90c is formed between the first clamp 413 and the second clamp 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.

[0133] 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 fixed-length film 90c is adsorbed by the gluing mechanism 500, and the cutting component 440 cuts the fixed-length film 90c, realizing the automatic gluing process.

[0134] 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 cutting edge of the cutting knife 441 and the first clamping jaw 413, so that after the fixed-length film 90c is cut, a section of the film 90 will still remain on the first clamping jaw 413 as a new rubber head to facilitate the second clamping jaw 433 to re-grasp, and the process is repeated. Fig.13 as well as Fig.14 Actions between.

[0135] When the film 90 on the film spool 310 has been consumed, the film spool 310 can rotate in the reverse direction. Fig.13 and Fig.14 As shown, the remaining film extending from the circumference of the film 90 to the right on the first clamping claw 413 is reversely rolled by the film reel 310 to form an empty reel 90b, effectively avoiding the situation where the film falls off and causes downtime; combined with Figure 8 As shown, the used empty roll 90b is removed from the film reel 310 by the shifting mechanism 200, and the film 90 to be used is transferred from the glue preparation mechanism 100 to the film reel 310 again, so that the next round of production process can be automatically started, which not only realizes the fully automatic glue sticking 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 roll 90b, saving manpower and reducing production costs.

[0136] 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.

[0137] In some possible embodiments, see Figure 1 , Figure 2 ,as well as Figures 11 to 14 As shown, the glue sticking 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.

[0138] 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 arranged 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 cutting component 440 cuts the fixed-length film 90c, and the fixed-length film 90c is separated from the film 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 and the battery.

[0139] Optionally, the adhesive bonding mechanism 500 includes two sets of mutually spaced action arms 520, so that the two sets of action arms 520 can be respectively adsorbed on both ends of the fixed-length film 90c, so as to facilitate the bonding with the battery. The spacing between the two sets of mutually spaced action arms 520 can be fixed in length, or can be designed to be movable and adjustable, so that the action arms 520 can be adjusted according to the different lengths of the fixed-length film 90c, so as to facilitate the adsorption and bonding.

[0140] A second aspect of the present application provides a battery production line, comprising the above-mentioned glue laminating equipment.

[0141] A third aspect of the present application is an automatic glue sticking method, which is applied to the above-mentioned glue sticking equipment.

[0142] See also Figures 1 to 15 As shown, the automatic gluing method includes:

[0143] S10, confirm that the consumption of the film 90 on the film reel 310 has reached a preset level. The controller (not shown) of the gluing device can sense the outer diameter of the film 90 on the film reel 310 through the second sensor 370 disposed on the support portion 320; thus, when the film 90 rotates forward to output the film, 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, and after receiving the signal, the controller determines that the film 90 on the film reel 310 has been consumed to a preset level and needs to be replaced with a new film 90.

[0144] 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 equipment can confirm under certain conditions that the film 90 on the film reel 310 has been consumed to a preset level and needs to be replaced with a new film 90, the specific design shall prevail.

[0145] S20, controlling the film reel 310 to rotate in the reverse direction, so that the film 90 on the film reel 310 rolls the remaining film on the outside in the reverse direction to form an empty reel 90b.

[0146] S30, control the shift mechanism 200 to remove the empty roll 90b from the film shaft 310. Specifically, the controller of the glue laminating 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.

[0147] 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 placing mechanism 300 .

[0148] By executing steps S20-S40 and coordinating the actions of various components, the automatic winding of the gluing equipment can be achieved, and the remaining film on the film 90 can be avoided from falling off and causing human intervention, so that the shifting mechanism 200 can automatically remove the empty roll 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 roll 90b, without the need for manual reverse rotation of the film 90 and manual removal of the empty roll 90b, effectively saving manpower.

[0149] In some possible embodiments, see Figures 1 to 15 As shown, after step S40, the automatic glue sticking method further includes:

[0150] S50, control the film reel 310 to rotate forward until the glue head 91 of the film 90 is aligned with the glue pulling mechanism 400. The controller of the glue sticking device controls the film reel 310 to rotate forward, thereby driving the film 90 to rotate forward, and when it rotates to a certain angle, the glue head 91 is aligned with the glue pulling mechanism 400; in this way, it is convenient for the glue pulling mechanism 400 to grab the glue head 91. The angle can also be determined by a sensor sensing the angle and feeding back a signal to the controller, which will not be repeated here.

[0151] S60, control the glue pulling mechanism 400 to grab the glue head 91 and pull out the film, and 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 along the first direction, and the film reel 310 rotates in coordination with the glue pulling mechanism 400, thereby driving the film 90 to continuously rotate forward to release continuous films, so that the glue pulling mechanism 400 can cut the film 90 on the film reel 310 to form a fixed-length film 90c.

[0152] S70, control the gluing mechanism 500 to grab the fixed-length film 90c for gluing. The controller of the gluing device controls the driving unit 510 to drive the action arm 520 to rise and fall, and uses the negative pressure suction cup 530 of the action arm 520 to absorb the fixed-length film 90c under negative pressure, and the driving unit 510 drives the action arm 520 to rise, thereby transferring the fixed-length film 90c, and making the fixed-length film 90c and the battery complete the corresponding gluing; the whole process does not require operator operation, thereby improving the production efficiency of the gluing device.

[0153] Thus, in steps S10-S70, through the cooperation of various components and the bidirectional rotation of the film reel 310, not only is the fully automatic gluing process of the battery realized with high efficiency and controllable and stable quality, and the film falling off and causing downtime can be 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.

[0154] In some possible embodiments, see Figures 1 to 16 As shown, 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 .

[0155] The S60 step specifically includes:

[0156] 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, so that the first clamping jaw assembly 410 can grab the adhesive head 91 conveniently.

[0157] S62, control the first clamping jaw assembly 410 to drive the adhesive head 91 to pass through the roller assembly 420 along the 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 completing the automatic film threading of the film roll 90, avoiding the process of manual threading, and effectively saving manpower.

[0158] 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 .

[0159] S64, controlling the roller assembly 420 to tension the film of the film roll 90. The controller of the gluing device controls the ninth driver 422 of the roller assembly 420 to rise or fall along the third direction, so that the plurality of rollers 421 of the roller assembly 420 tension the film of the film roll 90, ensuring that the film of the film roll 90 is always in a tensioned state, and avoiding wrinkles after the cutter assembly 440 cuts the fixed-length film 90c.

[0160] S65, control the second clamping jaw assembly 430 to move so as to form a fixed-length film 90c between the second clamping jaw assembly 430 and the first clamping jaw assembly 410. The controller of the glue laminating device controls the eighth driver 432 to drive the second clamping jaw 433 of the second clamping jaw assembly 430 to move the film of the film roll 90 along the first direction for a distance; thereby forming a fixed-length film 90c between the first clamping jaw 413 and the second clamping jaw 433.

[0161] S66, control the cutting component 440 to cut the fixed-length film 90c. The gluing mechanism 500 absorbs the fixed-length film 90c, 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 absorbed fixed-length film 90c and sticks it to the battery, thereby completing the process of automatic tape threading and automatic gluing, effectively saving manpower.
