[0002] With the rapid development of electric vehicles and automobiles, the demand for power batteries has also grown rapidly. During the lithium battery production process, several battery cells need to be stacked and compressed into a battery module. Before this, a double-sided adhesive tape segment is applied to the stacking surface of each battery cell.

[0003] In the related art, the large-surface gluing process for battery cells requires the use of a gluing device. The gluing device includes a base, a glue feeding mechanism, a battery cell conveying mechanism, and a battery cell flipping mechanism. The glue feeding mechanism, battery cell conveying mechanism, and battery cell flipping mechanism are arranged on the base, and the battery cell conveying mechanism is arranged below the glue feeding mechanism. The glue feeding mechanism is used to drive the continuous movement of the glue material. The battery cell is placed in a lying position on the battery cell conveying mechanism with the large surface facing up. The battery cell conveying mechanism and the glue feeding mechanism operate synchronously, and the battery cell is in a lying position to complete single-sided gluing. After the single-sided gluing is completed, the battery cell needs to be flipped by the battery cell flipping mechanism, from lying to upright and then back to lying, to achieve large-surface gluing on the opposite side of the battery cell.

[0004] However, the above-mentioned gluing method requires the battery cell to be clamped and turned over multiple times during the gluing process, which can easily cause bumps and damage to the battery cell itself, and can easily lead to exposure of the internal structure or electrolyte leakage caused by bumps and damage to the battery cell, thereby reducing the quality of battery production.

DETAILED DESCRIPTION

[0024] The following is combined with Figure 1-6 This application is described in further detail.

[0025] The embodiment of the present application discloses a vertical large-surface glue laminating machine for battery cells, referring to Figure 1 The vertical large-surface gluing machine for battery cells includes a conveying mechanism 1, a gluing mechanism 2, and a gluing mechanism 3. The conveying mechanism 1 is used to convey the battery cells, the gluing mechanism 2 is used to drive the glue 4 to load, and the gluing mechanism 3 is used to realize the bonding process between the glue 4 and the large-surface side of the battery cells. In the lithium battery processing and production process, the gluing process is adapted to multiple stages, such as the stage where single battery cells are glued together to form a beam, or the stage where multiple beams are glued together to form a module. The battery cell described in this solution can refer to either a single battery cell or a beam.

[0026] Reference Figure 1The conveying mechanism 1 includes a conveying base 101 and a conveying assembly 10. The conveying assembly 10 includes a conveying chain 102, a first conveying roller 103, and a second conveying roller 104.

The first conveying roller 103 and the second conveying roller 104 are symmetrically arranged on opposite sides of the conveying base 101 along the X-axis direction. The conveying chain 102, the first conveying roller 103, and the second conveying roller 104 cooperate to form a conveying space. After the battery cell moves onto the conveying chain 102, it enters the conveying space, which facilitates the positioning and subsequent movement of the battery cell. The first conveying roller 103 is located on the side of the conveying base 101 close to the gluing mechanism 2 and the gluing mechanism 3, and a notch is provided in the middle section of the first conveying roller 103. The notch makes way for the gluing mechanism 3 to facilitate automatic gluing of the large surface side of the battery cell.

[0027] Reference Figure 1 and 2 The conveying mechanism 1 also includes a conveying assembly 11, which includes a conveying truss 111 and a pressure piece. The conveying truss 111 is fixedly arranged above the conveying base 101. The pressure piece includes a pressure drive 112 and a pressure plate 113. The pressure drive 112 is fixedly arranged at the end of the conveying truss 111, and the pressure plate 113 is fixedly connected to the output end of the pressure drive 112. Specifically, the pressure drive 112 can use a pressure cylinder, which drives the pressure plate 113 to move along the Z-axis direction, and the pressure plate 113 is against the side of the battery cell.

The output end of the conveying drive 114 is coaxially connected to a conveying screw 1151, and the conveying frame 115 is threadedly connected to the conveying screw 1151.

[0028] Reference Figure 2 The transport assembly 11 also includes a positioning member, which includes a first positioning block 117, a mobile drive 118 and a second positioning block 119. The first positioning block 117 is fixedly connected to one end of the transport frame 115, and the mobile drive 118 is fixedly connected to the transport frame 115. Specifically, the mobile drive 118 uses a motor, and the output end of the mobile drive 118 is coaxially connected to a moving screw 1181. The second positioning block 119 is threadedly connected to the moving screw 1181. The mobile drive 118 drives the second positioning block 119 to move along the X-axis direction close to the first positioning block 117. The first positioning block 117 and the second positioning block 119 cooperate to clamp the battery cell.

[0029] Reference Figure 2The conveying mechanism 1 further includes a clamping assembly 12, which includes a clamping drive 121 and a clamping plate 122. The clamping drive 121 is a pneumatic cylinder. The clamping drive 121 is fixedly connected to the side of the conveying base 101, and the clamping plate 122 is fixedly connected to the output end of the clamping drive 121. There are at least two clamping assemblies 12, each two clamping assemblies 12 forming a group, which are arranged in a one-to-one correspondence along the Y-axis direction on opposite sides of the conveying base 101, that is, on the two opposite large sides of the battery cell. The clamping plates 122 are used to clamp the battery cell.

[0030] The battery cell moves onto the conveyor chain 102 in a standing position. When one end of the battery cell moves to abut against the first positioning block 117, the conveyor chain 102 stops. The clamping drive 121 drives the clamping plate 122 to move along the Y-axis, clamping the battery cell. The pressure drive 112 then controls the pressure plate 113 to move downward along the Z-axis, pressing it against the small side of the battery cell. The movement drive 118 then drives the second positioning block 119 to move, cooperating with the first positioning block 117 to clamp the battery cell. The transport rack 115 then continues to move with the battery cell to facilitate the subsequent gluing step.

[0031] Reference Figure 1 and 3 The gluing mechanism 2 includes a gluing base 21 and a gluing assembly 22. The gluing base 21 is disposed on one side of the conveying base 101. The gluing assembly 22 includes a gluing drive 221 and a gluing tray 222. The gluing drive 221 is fixedly connected to the gluing base 21, and the gluing tray 222 is rotatably connected to the gluing base 21. The gluing drive 221 can optionally be a motor, and the rotating shaft of the gluing tray 222 is connected to the output shaft of the gluing drive 221. The rubber material 4 is disposed on the rubber tray 222. The gluing drive 221 controls the rotation of the rubber tray 222 to release the rubber material 4.

[0032] Reference Figure 1 、 3 4. The gluing mechanism 2 also includes an adjustment assembly 23, which includes an adjustment plate 231, a first sensor, and a second sensor. The adjustment plate 231 is fixedly connected to the gluing base 21. A mating roller 232 is fixedly positioned above the adjustment plate 231. An adjustment roller 233 is slidably connected to the adjustment plate 231. The adjustment roller 233 moves relative to the mating roller 232 along the Z-axis. Multiple mating rollers 232 and adjustment rollers 233 are staggered along the X-axis, and the adhesive 4 is sequentially staggered around the mating rollers 232 and adjustment rollers 233. The first sensor and the second sensor are fixedly connected to the adjustment plate 231 along the Z-axis, with the first sensor positioned above the second sensor. Both the first sensor and the second sensor are used to detect the adjustment roller 233. Both the first sensor and the second sensor are electrically connected to the gluing drive 221.

[0033] If the rubber material 4 is being fed more tightly, the rubber material 4 drives the adjusting roller 233 to move closer to the matching roller 232 along the Z-axis direction. When the first sensor detects the adjusting roller 233, the first sensor sends a signal to the upper gluing drive 221. After receiving the signal, the gluing drive 221 accelerates the release of the rubber material 4. If the rubber material 4 is being fed more loosely, the rubber material 4 drives the adjusting roller 233 to move away from the matching roller 232 along the Z-axis direction. When the second sensor detects the adjusting roller 233, the second sensor sends a signal to the upper gluing drive 221. After receiving the signal, the gluing drive 221 slows down the release of the rubber material 4, so that the feeding of the rubber material 4 is automatically adjusted.

[0034] Reference Figure 3 and 4 The gluing mechanism 2 also includes a flip assembly 24, which includes a flip frame 241 and a flip rod 242. The flip frame 241 is fixedly connected to the gluing base 21, and both ends of the flip rod 242 are fixedly connected to the flip frame 241. The axial direction of the flip rod 242 is tilted relative to the ground along the vertical direction. Specifically, the tilt angle is 45 degrees. After the adhesive 4 is released, it is wound around the flip rod 242 to achieve the change of the angle of the adhesive 4 during the feeding process. The adhesive 4 is alternately wound around the matching roller 232 and the adjustment roller 233 along the Z-axis direction. Then, it passes through the flip rod 242, causing the feeding direction of the adhesive 4 to be flipped from the Z-axis direction to the X-axis direction, so that the adhesive 4 can adapt to the large surface side of the battery cell.

[0035] Reference Figure 3 and 4 The gluing mechanism 2 also includes a conveying assembly 25. A mounting platform 210 is provided on the gluing base. The conveying assembly 25 includes a conveying drive 251, a conveying roller 252, and a clamping roller 253. The conveying drive 251 is fixedly connected to the bottom of the mounting platform 210, and the conveying roller 252 is rotatably connected to the mounting platform 210. The conveying drive 251 controls the rotation of the conveying roller 252. The clamping roller 253 and the conveying roller 252 rotate along the Y-axis. After being flipped by the flipping rod 242, the adhesive material 4 passes between the clamping roller 253 and the conveying roller 252, and the rotation of the conveying roller 252 drives the adhesive material 4 to continue to move. There are two sets of conveying assemblies 25 on the mounting platform 210: one set of conveying assemblies 25 is closer to the flipping assembly 24, and the other set of conveying assemblies 25 is closer to the conveying base 101. These provide the power to move the adhesive material 4 during the gluing process.

[0036] Reference Figure 3 The gluing mechanism 2 also includes a detection part 26, which is fixedly connected to the mounting platform 210. The adhesive material 4 is passed through the detection part 26. The detection part 26 is used to detect whether the adhesive material 4 is broken or contaminated. If the detection part 26 detects that the adhesive material 4 does not meet the gluing processing requirements, an alarm will be issued to facilitate timely processing by the operator.

[0037] Reference Figure 3 The gluing mechanism 2 further includes a leveler 27, which is disposed on the mounting platform 210. Specifically, the leveler 27 is an adaptive leveler 27. After the adhesive 4 passes the inspection of the inspection unit 26 and is wound onto the leveler 27, the leveler 27 automatically levels the adhesive 4, so that the edge of the adhesive 4 is aligned with the surface of the mounting platform 210.

[0038] Reference Figure 3 The gluing mechanism 2 also includes a separation component 28 and a recovery component 29. The separation component 28 includes a separation knife 281 and a separation column 282. The separation knife 281 and the separation column 282 are fixed on the gluing base 21. The adhesive material 4 is wound around the blade end of the separation knife 281. The separation knife 281 separates the adhesive material 4 from the release paper 5. After the release paper 5 is separated from the adhesive material 4, it is wound around the separation column 282, and then the release paper 5 is centrally recovered through the recovery component 29.

[0039] Reference Figure 5 The gluing mechanism 3 includes a gluing base 301, a smoothing component and a gluing component. The gluing base 301 is fixedly connected to the conveying base 101, and the gluing base 301 is arranged at one end of the gluing base 21 close to the conveying base 101, so that after the glue material 4 and the battery cell are synchronously moved into place, the smoothing component clamps and smoothes the end of the clamped material, and the gluing component realizes the gluing process.

[0040] Reference Figure 5 and 6 The smoothing component includes a first smoothing base 31 and a second smoothing base 32. The first smoothing base 31 is fixed on the glue base, and the second smoothing base 32 is slidably connected to the glue base along the X-axis direction. A first smoothing piece 33 is provided on the first smoothing base 31, and a second smoothing piece 34 is provided on the second smoothing base 32. After the rubber material 4 passes through the first smoothing piece 33, the second smoothing piece 34 clamps the rubber material 4 and passes through one end of the first smoothing piece 33.

[0041] Reference Figure 5 and 6The first smoothing member 33 includes a smoothing drive 331, a first smoothing plate 332, and a second smoothing plate 333. The smoothing drive 331 is fixedly connected to the first smoothing base 31, the first smoothing plate 332 is fixedly connected to the side of the first smoothing base 31 close to the conveying base 101, and the second smoothing plate 333 is fixedly connected to the output end of the smoothing drive 331. The smoothing drive 331 is used to drive the second smoothing plate 333 to move relative to the first smoothing plate 332 along the Y-axis direction. The rubber material 4 passes between the first smoothing plate 332 and the second smoothing plate 333, and the second smoothing plate 333 moves close to the first smoothing plate 332. The two smoothing plates cooperate to clamp the rubber material 4. The structure and operating principle of the second smoothing member 34 are basically the same as those of the first smoothing member 33 and will not be repeated here. After the rubber material 4 passes through the first smoothing member 33, the end portion extends into the second smoothing member 34. The second smoothing member 34 cooperates with the first smoothing member 33 to clamp and smooth the rubber material 4 for subsequent gluing.

[0042] Reference Figure 5 and 6 The glue sticking assembly includes a first slide 35, a second slide 36 and a glue sticking roller 37. The first slide 35 is connected to the second smoothing base 32 by sliding along the X direction, and the second slide 36 is connected to the first slide 35 by sliding along the Y axis direction. The glue sticking roller 37 is rotatably connected to one end of the second slide 36 toward the conveying base 101. The first slide 35 and the second slide 36 move in coordination, driving the glue sticking roller 37 to abut against the side of the glue material 4 facing away from the battery cell.

[0043] Reference Figure 5 and 6 The gluing mechanism 3 also includes a cutting component 38, which includes a cutting drive 381 and a cutting knife 382. The cutting drive 381 is fixedly connected to the first smoothing base 31, and the cutting knife 382 is fixedly connected to the output end of the cutting drive 381. The cutting drive 381 is used to drive the cutting knife 382 to move along the Z-axis direction. After the current battery cell is glued, the cutting drive 381 drives the cutting knife 382 to move and cuts the glue material 4 at the same time.

[0044] The battery cell and the adhesive material 4 are conveyed and moved synchronously. The battery cell stops when it reaches the notch. After the adhesive material 4 passes through the first smoothing member 33, the second smoothing base 32 moves closer to the first smoothing base 31. The second smoothing member 34 grips the end of the adhesive material 4 and flattens it. The second smoothing member 34 then moves away from the first smoothing member 33 to make way for the adhesive roller 37. The first slide 35 then moves toward the first smoothing base 31, while the second slide 36 moves along the Y-axis toward the adhesive material 4, causing the adhesive roller 37 to contact the adhesive material 4. The transport assembly 11 continues to move with the battery cell, and the adhesive material 4 is continuously applied, achieving automatic adhesive application.

[0045] The implementation principle of the vertical large-surface glue laminating machine for battery cells in the embodiment of the present application is as follows: The battery cell enters the conveyor space in a standing position. As the conveyor chain 102 moves, the first conveyor roller 103 and the fourth conveyor roller cooperate to maintain the cell's position. When the cell moves to abut against the first positioning block 117, the pressure plate 113 presses down on the side of the cell. The second positioning block 119 then moves toward the first positioning block 117 and clamps the cell. The transport rack 115 carries the cell and continues to move to the gap in the first conveyor roller 103.

[0046] The rubber disc is set on the rubber disc rack 222, and one end is released and stretched out to be wound around the matching roller 232 and the adjustment roller 233, and then passed between the clamping roller 253 and the conveying roller 252. After passing through the detector and the leveler 27 in turn, it is wound around the end of the separation knife 281 to achieve the separation of the release paper 5 and the rubber material 4.

The transport assembly 11 carries the battery cell and continues to move to complete the glue application. S7: Cutting: After the adhesive is applied, the cutting drive 381 drives the cutting knife 382 to move and cut the adhesive material 4. After cutting, the cutting knife 382 is reset. S8: The transport assembly 11 carries the battery cell and moves close to the first conveyor roller 103, and then the conveyor chain 102, the first conveyor roller 103 and the second conveyor roller 104 cooperate to continue to drive the battery cell to the next workstation. Synchronously, the positioning piece is reset, the pressure plate 113 is reset, and the transport rack 115 is reset.
