Description

[0001] This application is a divisional application of Chinese invention patent application No. 202110834519.X, filed on July 23, 2021, entitled "An automatic application device for a tail sticker with an anti-drop soft-pack lithium battery cell". Technical Field

[0002] This invention relates to the field of soft-pack lithium battery technology, specifically to an automatic bonding device for the tail sticker of a soft-pack lithium battery. Background Technology

[0003] A pouch lithium battery is a liquid lithium-ion battery encased in a polymer shell. Structurally, it is packaged in an aluminum-plastic film. In the event of a safety hazard, a pouch battery will at most swell and crack. Once the protective circuit board is removed, the pouch lithium battery cell is what remains. It is the energy storage component of the pouch lithium battery, and the quality of the pouch lithium battery cell directly determines the quality of the pouch lithium battery. During the manufacturing process of the pouch lithium battery cell, the tail end needs to be wrapped with a heat-resistant sticker.

[0004] For example, an automatic sticker-applying machine with publication number CN212024323U uses a conveyor to transport the material to be stickered. When the material is conveyed to the bottom of the second positioning ring, the conveyor stops moving under the control of an external control program. Then, the drive motors at the rear end of the winding shaft and the right side of the insertion ring are started. After the right side insertion ring rotates to a length equal to the outer diameter of the second positioning ring, it stops rotating under the control of an external system. Then, the second electric telescopic rod is started. The second electric telescopic rod drives the connecting block and the first positioning ring to move downward, thereby squeezing the sticker through the rubber ring. At this time, the first electric telescopic rod is started. The first electric telescopic rod drives the pressure block to move downward. The cutting ring moves downward to cut the sticker. The cut sticker moves downward with the pressure block. When the cutting ring and the material squeeze each other, this device still has some shortcomings.

[0005] 1. Most existing automatic bonding devices use conveyor belts for movement during the feeding process. The positioning of this movement method is not accurate, which causes offset in the subsequent bonding work.

[0006] 2. Most existing automatic bonding devices stick the sticker to one side of the item, while soft-pack lithium battery cells need to be pasted around the tail. This makes many automatic bonding devices require secondary or multiple pasting, which is more troublesome to use.

[0007] 3. Existing automatic bonding devices simply stick the sticker on when bonding the end of the soft-pack lithium battery cell, which often results in the sticker not being firmly attached, causing it to fall off later and affecting the quality of the soft-pack lithium battery cell.

[0008] To address the aforementioned issues, there is an urgent need for innovative design based on the existing automatic bonding device structure. Summary of the Invention

[0009] The purpose of this invention is to provide an automatic bonding device for the tail sticker of a soft-pack lithium battery cell, to solve the problems mentioned in the background art. Existing automatic bonding devices mostly use conveyor belts for movement during the feeding process, which is not accurate in positioning, causing misalignment during subsequent bonding. Furthermore, most existing automatic bonding devices only apply the sticker to one surface of the item, while soft-pack lithium battery cells require bonding to the four sides of the tail. This forces many automatic bonding devices to perform secondary or multiple bonding operations, making them cumbersome to use. Moreover, existing automatic bonding devices simply adhere the sticker to the tail of the soft-pack lithium battery cell, often resulting in weak adhesion and subsequent sticker falloff, thus affecting the quality of the soft-pack lithium battery cell.

[0031] Compared with the prior art, the present invention has at least the following beneficial effects:

[0032] 1. The large slide table forms a sliding structure with the worktable through the first threaded shaft and the first guide rod. The first chuck forms a sliding structure with the large slide table through the first telescopic rod and the second guide rod. The first trapezoidal slider forms a sliding structure with the first chuck through the second telescopic rod.

The upper side of the top block passes through the arrangement chamber and is movably connected to the soft-pack lithium battery cells. After the soft-pack lithium battery cells are placed into the arrangement chamber, they are all squeezed to the right by the pushing block. The top block pushes out a section of the rightmost soft-pack lithium battery cell. Then, the first chuck descends, and the two first claws slide to clamp the pushed-out soft-pack lithium battery cell. Then, the first chuck rises to pull the soft-pack lithium battery cell out of the arrangement chamber. The large slide table drives the soft-pack lithium battery cell to move left and right, thus facilitating the movement and positioning of the soft-pack lithium battery cell.

[0033] 2. A sticker holder is fixedly installed on the front left side of the pasting table. A sticker roll is fitted on the front side of the sticker holder. A sticker baffle is fixedly installed on the front end of the sticker holder by bolts. Two guide rollers are fixedly installed on the front left side of the pasting table. A knife holder is fixedly installed on the upper right side of the pasting table. A cutting blade is movably connected to the inner side of the knife holder. A U-shaped platform is fixedly installed on the upper right side of the pasting table. A small slide is connected to the pasting table via a second threaded shaft and a third guide rod to form a sliding structure. A cutting blade is fixedly installed on the upper side of the knife handle. The knife handle is connected to the pasting table via a fourth telescopic rod to form a lifting structure. A second chuck is connected to the small slide via a fourth guide rod and a fifth telescopic rod to form a sliding structure. A second trapezoidal slider is connected to the second chuck via a sixth telescopic rod. A second jaw is connected to the second chuck via a second trapezoidal slider to form a sliding structure. A portion of the sticker from the sticker roll is pulled out, so that the adhesive side of the sticker is facing upwards, passing between the two guide rollers. Then, the second chuck moves forward via the fourth guide rod and the fifth telescopic rod, and then clamps one end of the sticker with the two second jaws. The second chuck moves to the right via the small slide, reaching the right side of the U-shaped platform. Then... A first chuck carrying a pouch lithium battery cell moves to the top of a U-shaped platform. The first chuck then descends with the pouch lithium battery cell, and during its descent, the tail of the pouch lithium battery cell contacts the sticker until it lands in the U-shaped platform. The U-shaped platform then wraps the tail of the pouch lithium battery cell with the sticker, so that the sticker covers the tail of the pouch lithium battery cell. Then, the second chuck releases the sticker, and the second chuck moves backward, then to the left, and finally forward to the left side of the cutter holder, where it clamps the sticker. Then, the cutting blade rises and cuts the sticker. The first chuck moves the pouch lithium battery cell with the sticker on its tail out of the U-shaped platform, so that the sticker can be automatically applied to the tail of the pouch lithium battery cell in one go.

[0034] 3. A shrinking airbag is provided inside the bonding chamber. A connecting pipe is fixedly installed at the lower end of the shrinking airbag.

Then the piston 51 rises, causing the air in the pressure chamber 50 to enter the contraction airbag 48 through the connecting pipe 49. The air in the contraction airbag 48 expands, and the expansion of the contraction airbag 48 fully adheres the sticker to the soft-pack lithium battery cell 19, making the sticker and the soft-pack lithium battery cell 19 adhere more firmly. Then the piston 51 descends, and the air in the contraction airbag 48 returns to the pressure chamber 50. The contraction airbag 48 contracts, and the first retainer 10 removes the soft-pack lithium battery cell 19 and places it in the storage basket 54.

[0051] The working principle of the automatic bonding device in this embodiment is as follows: When using this automatic bonding device for the tail sticker of a soft-pack lithium battery cell, firstly according to... Figure 1-5The structure shown first involves placing the soft-pack lithium battery cell 19 into the arrangement chamber 15. The pushing block 18 moves to the right under the force of the spring 16, and the soft-pack lithium battery cell 19 moves to the right under the pressure of the pushing block 18. The top block 23 can move up and down via the third telescopic rod 22. When the top block 23 rises, it pushes out the rightmost soft-pack lithium battery cell 19 by a section. The first retainer 10 can move up and down via the first telescopic rod 8 and the second guide rod 9. Then, the first retainer 10 descends, and the first trapezoidal slider 13 moves up and down via the second telescopic rod 9. The retractor 12 moves up and down, and the first trapezoidal slider 13 moves up and down, causing the two first claws 14 to slide left and right. The two first claws 14 slide to clamp the protruding soft-pack lithium battery cell 19. Then the first chuck 10 rises to pull the soft-pack lithium battery cell 19 out of the arrangement chamber 15. The first motor 3 is started, and the first motor 3 drives the first threaded shaft 4 to rotate. The large slide table 6 moves left and right through the first threaded shaft 4 and the first guide rod 5, and drives the soft-pack lithium battery cell 19 to move left and right through the large slide table 6.

[0052] according to Figure 6-9 As shown, a portion of the sticker is pulled out from the sticker roll 26, so that the adhesive side of the sticker faces upwards, and passes between the two guide rollers 28. The second clamping shell 42 can move back and forth via the fourth guide rod 41 and the fifth telescopic rod 40. Then, the second clamping shell 42 moves forward, and the second trapezoidal slider 45 can slide back and forth via the sixth telescopic rod 44. The back and forth movement of the second trapezoidal slider 45 causes the two second clamping claws 46 to slide up and down, and then the two second clamping claws 46 clamp one end of the sticker. The second motor 35 is started, and the second motor 35 drives the second threaded shaft 36 to rotate. The third guide rod 37 and the small slide table 38 can move left and right via the second threaded shaft 36 and the third guide rod 37. The second clamping shell 42 moves to the right via the small slide table 38, reaching the U-shaped platform. On the right side of 34, the first chuck 10 moves the soft-pack lithium battery cell 19 to the top of the U-shaped platform 34. The first chuck 10 then lowers the soft-pack lithium battery cell 19. During the descent, the tail of the soft-pack lithium battery cell 19 contacts the sticker until it falls into the U-shaped platform 34. The U-shaped platform 34 then wraps the tail of the soft-pack lithium battery cell 19 in the sticker, so that the sticker covers the tail of the soft-pack lithium battery cell 19. Then the second chuck 46 releases the sticker, and the second chuck 42 moves backward, then to the left, and finally forward to the left side of the blade holder 33, where it clamps the sticker. The blade handle 31 drives the cutting blade 32 to rise through the fourth telescopic rod 30 to cut the sticker. The first chuck 10 moves the soft-pack lithium battery cell 19 with the sticker on its tail out of the U-shaped platform 34.

[0053] according to Figure 10As shown, the first retainer 10 inserts the soft-pack lithium battery cell 19 with a sticker attached to its tail into the bonding chamber 47. The piston 51 can slide up and down via the seventh telescopic rod 52. Then, the piston 51 rises, causing the air in the pressure chamber 50 to enter the contraction airbag 48 through the connecting pipe 49. The air in the contraction airbag 48 expands, causing the sticker to adhere completely to the soft-pack lithium battery cell 19, making the sticker and the soft-pack lithium battery cell 19 adhere more firmly. Then, the piston 51 descends, and the air in the contraction airbag 48 returns to the pressure chamber 50. The contraction airbag 48 contracts, and the first retainer 10 removes the soft-pack lithium battery cell 19 and places it in the storage basket 54. This completes the working process of the device.
