[0002] In the related art, during the manufacturing process of lithium batteries and other square battery cells, the cells need to be glued, that is, the tape is attached to the side of the cell and the two large surfaces adjacent to the side, and then the tape is attached to the cell in a "C" shape.

[0003] The utility model with application number CN202322904095.7 discloses a battery cell gluing device, including a battery cell feeding mechanism, a tape feeding mechanism and a gluing mechanism. The battery cell feeding mechanism is used to receive battery cells at the battery cell position to be received and send them to the battery cell position to be glued; the tape feeding mechanism is arranged on one side of the battery cell feeding mechanism and is L-shaped with the battery cell position to be glued, and the tape feeding mechanism is used to provide the tape to be glued; the gluing mechanism is arranged opposite to the tape feeding mechanism so as to absorb the tape to be glued, and the battery cell feeding mechanism is also arranged opposite to the battery cell feeding mechanism so as to paste the absorbed tape to be glued on the battery cell at the battery cell position to be glued; thus, through reasonable spatial layout, the cut tape can quickly reach the battery cell position to be glued for gluing, which not only reduces the occupied space but also improves the gluing efficiency.

[0059] The present invention is described in detail below with reference to the accompanying drawings.

[0060] like Figure 1-9 As shown, the lithium battery bottom glue application equipment includes a glue preparation mechanism 1 and a glue application mechanism 6.

[0061] The glue preparation mechanism 1 includes a laterally movable glue preparation drive base 16, which is mounted with the unwinding assembly 10 and the waste collection assembly 2. A glue preparation base plate 17 is provided at the bottom of the glue preparation base plate 16. A bottom guide rail 18 is provided along its length. Multiple bottom slides are slidably mounted on the bottom guide rail 18, and the bottom slides are connected to the glue preparation drive base 16. Also provided at the bottom of the glue preparation base plate is a bottom telescopic cylinder 19 arranged parallel to the bottom guide rail 18. The driving end of the bottom telescopic cylinder 19 is connected to the glue preparation drive base 16, thereby driving the glue preparation drive base 16 toward or away from the glue application mechanism 6.

[0062] The unwinding assembly 10 includes a rotatable unwinding shaft 11, on which is mounted an unwinding base plate 12, on which are mounted a plurality of axially inclined elastic fastening plates 13, the elastic fastening plates 1-3 being capable of elastically resisting against the inner ring wall of the unwinding disk; the waste collecting assembly 2 includes a rotatable waste collecting shaft 21, on which is mounted a waste collecting cylinder 22, which is mounted a waste collecting base plate 23 and a waste collecting top plate 24 arranged at intervals, the waste collecting base plate 23 and the waste collecting top plate 24 being coaxially formed with a movable hole 25 cooperating with the waste collecting cylinder 22, the hole wall of the movable hole 25 being formed with a guide groove 26, an axially arranged guide rod 27 being fitted on the outer ring wall of the waste collecting cylinder 22, the guide rod 27 being slidably fitted with the guide groove 26, and the waste collecting top plate 24 being axially slidable and removable and mounted on the waste collecting cylinder 22.

[0063] The adhesive reel to be unwound is sleeved on the unwinding shaft 11, and the elastic fastening piece 13 of the unwinding shaft 11 can bear against the inner ring wall of the adhesive reel under the action of the elastic seat, thereby fastening the adhesive reel and realizing the unwinding of the adhesive tape by synchronous rotation with the unwinding shaft 11; the waste tape after unwinding is wound and collected by the waste collection drum 22 of the waste collection shaft 21; when the waste collection shaft 21 is fully loaded with waste, the waste collection top plate 24 located at the waste collection drum 22 is slidably matched with the guide groove 26 through the guide rod 27, and the waste collection top plate 24 can be axially slidably removed from the waste collection drum 22 without the need for tedious operations such as screwing, which makes disassembly and assembly simple, reduces the pause time, and improves the unwinding efficiency.

[0064] Preferably, the elastic fastening piece 13 is driven by a spring to radially pop out, thereby fastening and locking the rubber disc sleeved on the unwinding shaft 11 .

[0065] The waste collection component 2 also includes a guide base plate 15 that is laterally connected to the rubber preparation drive seat 16. A torque motor 28 is installed at the bottom of the guide base plate 15, and the drive end of the torque motor 28 is connected to the waste collection shaft 21. The mechanical characteristics of the torque motor 28 are relatively soft, that is, as the load increases, the speed of the motor will automatically decrease, thereby keeping the output torque relatively stable. This characteristic enables the torque motor 28 to automatically adjust the output when the load changes, ensuring the stability of the system. Strong overload capacity: It can withstand a large overload load and can output a torque exceeding the rated torque in a short time. It is suitable for some occasions that need to deal with instantaneous overload conditions. Fast response: It has a fast response speed to the input signal and can quickly adjust the output torque and speed to meet the needs of some applications with high dynamic response requirements. Good characteristic linearity and small torque fluctuation: The output torque has a good linear relationship with the input current or voltage, and the torque fluctuation is small, which is conducive to achieving precise control. The speed can be adaptively adjusted according to the tension of the rubber reel during unwinding, and the waste tape can be stably rewound to prevent the waste tape from breaking during rewinding.

[0066] The guide base plate 15 is also equipped with a permanent magnetic brake 14. The braking end of the permanent magnetic brake 14 is sleeved on the unwinding shaft 11. The unwinding shaft 11 is a driven structure. The unwinding is achieved by driven rotation according to the rotation of the waste collecting shaft 21 of the waste collecting assembly 2. When there is a pause or the tape becomes loose during transmission, the permanent magnetic brake 14 can stop the unwinding shaft 11 and suspend the unwinding to prevent the tape from falling off.

[0067] The unwinding assembly 10 also includes a plurality of conveyor rollers 3 for conveying the tape. The conveyor rollers 3 are longitudinally mounted on the adhesive preparation drive base 16. The unwound tape is conveyed forward by the conveyor rollers 3. A tensioning roller 30 is provided next to the conveyor rollers 3. The adhesive preparation drive base 16 is laterally formed with a tensioning adjustment slot 31. A tensioning support block 32 is slidably mounted in the tensioning adjustment slot 31. The tensioning roller 30 is rotatably mounted on the tensioning support block 32. The tensioning support block 32 can move closer to or farther from the conveyor roller 3 along the tensioning adjustment slot 31.

[0068] In this embodiment, when the tension of the tape needs to be adjusted during transmission, the tension support block 32 can move closer to or away from the transmission roller 3 along the tension adjustment groove 31 to adjust the tension and prevent the tape from loosening or breaking.

[0069] Furthermore, a tensioning telescopic cylinder 33 and a tensioning adjustment rail 34 parallel to the tensioning adjustment groove 31 are installed at the bottom of the preparation glue driving seat 16, and the tensioning adjustment rail 34 is installed with a bottom sliding seat 35. The bottom sliding seat 35 is connected to the tensioning support block 32, and the driving end of the tensioning telescopic cylinder 33 is connected to the tensioning support block 32; under the drive of the tensioning telescopic cylinder 33, the tensioning support block 32 slides along the tensioning adjustment groove 31, and at the same time, the bottom sliding seat 35 connected to the tensioning support block 32 slides along the tensioning adjustment rail 34, thereby improving the stability of the movement of the tensioning support block 32.

[0070] Furthermore, the glue preparation drive seat 16 is further provided with a glue dragging mechanism 4 , a glue clamping mechanism 5 and a cutting mechanism 53 .

[0071] The laminating mechanism 5 comprises a laminating locating seat 51 and a laminating seat 52 spaced apart to the side of the laminating locating seat 51. The tape passes between the laminating seat 52 and the laminating locating seat 51 to be clamped by the laminating mechanism. The laminating seat 52 can move laterally toward or away from the laminating locating seat 51. During cutting, the laminating seat 52 approaches the laminating locating seat 51 until it is in contact, clamping the end of the tape. This prevents the tape from breaking during cutting, leaving a portion for the laminating mechanism to continue pulling forward.

[0072] The cutting mechanism 53 includes a transversely arranged cutting drive seat 54 located between the tape dragging mechanism and the tape clamping mechanism 5. The cutting drive seat 54 moves perpendicular to the tape's forward direction and is equipped with a cutting blade 55. The tape dragging mechanism 4 includes a clamping drive seat 41 that moves toward or away from the conveyor roller 3. This clamping drive seat 41 is equipped with a clamping member 42 that can open and close. After the tape is conveyed, the clamping drive seat 41, equipped with the clamping member 42, approaches the conveyor roller 3, clamps the outer end of the tape, and drags it outward to the desired length.

[0073] Before cutting, the glue-pulling mechanism 4 approaches the glue-clamping mechanism 5 via the clamping drive seat 41, clamps the tape, and then retracts and drags it. After retracting to the desired length, the glue-clamping mechanism 5 clamps the rear end of the tape through the cooperation of the glue-clamping seat 52 and the glue-clamping positioning seat 51. At this time, the cutting mechanism 53 is activated, and the cutting drive seat 54, driven by the telescopic cylinder, approaches the tape, thereby cutting the tape. During cutting, the glue-clamping mechanism 5 can prevent the tape from breaking, and can reserve a portion for the debonding mechanism to continue pulling it back for the next cutting.

[0074] Preferably, the glue dragging mechanism 4 also includes a conveyor belt 43 arranged along the movement direction of the clamping drive seat 41, and one of the long side sections of the conveyor belt 43 is equipped with a transmission seat 44, which is connected to the clamping drive seat 41. The clamping drive seat 41 is equipped with a clamping finger cylinder 45 that drives the clamping member 42 to open and close. When the conveyor belt 43 moves, the transmission seat 44 will move in a straight line, thereby driving the clamping drive seat 41 to move close to or away from the conveyor roller 3, and then clamping the tape under the drive of the clamping finger cylinder 45.

[0075] After passing through the glue preparation mechanism 1, the adhesive tape is driven by the glue dragging mechanism 4 to move to the bottom of the glue applying mechanism 6. The glue applying mechanism 6 includes a glue applying drive seat 60 that can move laterally and longitudinally. The glue applying drive seat 60 is provided with a laterally arranged positioning seat 62 for laterally supporting the battery. The top and bottom surfaces of the positioning seat 62 are respectively slidably mounted with a glue rolling assembly 61. The glue rolling assembly 61 includes a glue pressing roller 74 and a glue pressing seat 63. The outer end surface of the glue pressing seat 63 is used to position the adhesive tape. When the glue pressing seat 63 moves laterally, the adhesive tape is tightly attached to the surface of the battery through the bottom surface of the glue pressing seat 63.

[0076] The gluing mechanism 6 cooperates with the tape located in the glue preparation mechanism 1 through the movement of the gluing drive seat 60 to achieve gluing of the battery. During gluing, the two sets of glue rolling assemblies 61 move simultaneously. The glue pressing seat 63 first bends the tape attached to the side of the battery 90 degrees to the surface, so that the upper half of the tape is attached to the top surface of the battery and the lower half of the tape is attached to the bottom surface of the battery. Then, the glue pressing roller 74 rolls with the top and bottom surfaces of the battery to roll the initially attached tape, thereby improving the adhesion stability between the tape and the battery and preventing the tape from falling off the battery. Without moving the battery cell, the gluing mechanism 6 can realize U-shaped gluing and can apply glue to multiple surfaces of a product. It can ensure a certain degree of accuracy in the gluing function. It is also relatively convenient to collect and release materials. Maintenance and debugging are relatively convenient.

[0077] The outer end surface of the glue pressing seat 63 is provided with a plurality of adsorption holes 64 for adsorbing the tape; initially, after the tape is in place, the upper and lower parts of the tape are respectively adsorbed and positioned through the adsorption holes 64 of the glue pressing seat 63, and then the battery is laterally approached to the side of the positioning seat 62 where the tape is positioned, and then the side of the battery is attached to the middle of the tape and presses the positioning seat 62 at the same time, waiting for subsequent attachment.

[0078] The rubber rolling assembly 61 also includes a rubber rolling drive seat 65, which is respectively equipped with the rubber pressing roller 74 and the rubber pressing seat 63. The rubber rolling drive seat 65 is provided with an elastic drive structure 7 that drives the rubber pressing roller 74 to elastically press against the lateral end surface of the rubber application drive seat 60; the elastic drive structure 7 includes a rubber roller drive seat 71 installed on the rubber rolling drive seat 65, and a rolling drive groove 72 is provided at the bottom of the rubber roller drive seat 71. The rubber roller drive seat 71 is equipped with a mounting bracket 73 that can swing longitudinally through the rolling drive groove 72 and the structure of the shaft hole, and the rubber pressing roller 74 is rotatably mounted on the bottom of the mounting bracket 73 through the shaft hole structure; a compression spring 75 is provided between the rubber application drive seat 60 and the mounting bracket 73. In this embodiment, initially, the glue roller driving seat 65 does not extend outward, and the mounting bracket 73 installed on the glue roller driving seat 71 is elastically driven by the compression spring 75, and the mounting bracket 73 will swing downward, so that the glue pressing roller 74 installed at the bottom of the mounting bracket 73 will press against the top or bottom surface of the positioning seat 62; after moving horizontally, the glue pressing roller 74 will be elastically driven by the compression spring 75 and will adaptively press against the positioning seat 62 and the battery surface according to the height, so that the tape can be quickly attached to the battery cell, thereby increasing the glue sticking efficiency and ensuring the glue sticking quality.

[0079] The glue driving seat 60 is provided with a transverse driving member 8 that drives the glue rolling assembly 61 to move transversely along the glue driving seat 60. The transverse driving member 8 includes transverse driving seats 81 that are respectively slidably installed on the top and bottom surfaces of the glue driving seat 60, and a longitudinal connecting plate 82 is connected between the two transverse driving seats 81; under the connection of the longitudinal connecting plate 82, the transverse driving seats 81 located at the top and bottom of the glue driving seat 60 can move laterally synchronously at the same time, and the two glue rolling assemblies 61 move at the same time to achieve simultaneous gluing of the top, bottom and side surfaces of the battery.

[0080] Furthermore, the transverse driving member 8 also includes a guide rail 83 arranged along the length direction of the glue driving seat 60, and the guide rail 83 is slidably installed with a guide sliding seat 84, and the guide sliding seat 84 is connected to the transverse driving seat 81; the glue driving seat 60 is provided with a transverse telescopic cylinder 85 along the length direction, and the transverse telescopic cylinder 85 is connected to the longitudinal connecting plate 82; the transverse telescopic cylinder 85 drives the longitudinal connecting plate 82 to move transversely, and the transverse driving seat 81 moves along the guide rail 83 through the guide sliding seat 84, further improving the stability of the transverse movement.

[0081] The gluing mechanism 6 also includes a gluing drive mechanism 9 that drives the gluing drive seat to move horizontally and vertically. The gluing drive mechanism 9 includes a horizontally arranged gantry 91, and the gantry 91 has a horizontal linear module 92 arranged horizontally along its length. The driving end of the horizontal linear module 92 is installed with a horizontal sliding seat 93, and the horizontal sliding seat 93 is installed with a vertically arranged vertical driving plate 94. The vertical driving plate 94 is installed with a vertically arranged vertical lifting cylinder 95. The driving end of the vertical lifting cylinder 95 is installed with a vertical lifting seat 96 that moves up and down along the vertical driving plate 94. The vertical lifting seat 96 is connected to the gluing drive seat 10, and the gluing drive seat 10 can achieve lifting movement. Driven by the horizontal linear module 92 and the vertical lifting cylinder 95, the gluing drive seat 10 can move horizontally and vertically, and can absorb the prepared adhesive tape for battery gluing.
