[0002] With the continuous maturity and advancement of energy manufacturing technology, the market demand for power batteries has shown strong growth, and improving battery quality and safety has received increasing attention. Among them, the cell coating process plays a relatively important role in improving the quality of the cell. In order to prevent the bare cell from being scratched on the surface during transportation and assembly, which leads to leakage, a layer of insulating film needs to be coated on the outside of the bare cell before the cell is installed into the shell. By sticking L-shaped tape, the insulating film and the bare cell can be tightly fitted together, which not only ensures the compact size of the cell, but also ensures the smooth progress of the subsequent cell shelling process, avoids scratches, and improves the safety performance of the cell.

[0003] However, since the L-type glue itself is not very sticky, it is easy for the insulating film to become loose due to loose adhesion, or even wrinkles.

The device also includes a conveying mechanism (not shown in the figure) and a gantry 400, wherein the conveying mechanism is arranged through the gantry 400, the glue feeding mechanism 200 is arranged on the gantry 400, and the glue placing mechanism 100 and the glue pressing mechanism 300 are respectively arranged on both sides of the conveying mechanism.

[0053] The adhesive dispensing mechanism 100 is used to pull the adhesive tape out of the adhesive tape roll and cut it into adhesive tape segments of suitable sizes;

[0054] The glue unwinding mechanism 100 includes a workbench 10, a unwinding assembly 11, a glue pulling assembly 12 and a glue cutting assembly 13. The unwinding assembly 11, the glue pulling assembly 12 and the glue cutting assembly 13 are all arranged on the workbench 10, and the glue cutting assembly 13 is arranged between the unwinding assembly 11 and the glue pulling assembly 12.

[0055] The unwinding assembly 11 is used to place the tape reel 500 to ensure the continuous supply of the tape 501;

[0056] The unwinding assembly 11 includes a reel support 111, a reel seat 112, a reel shaft 113, a magnetic damper 114 and a rotating wheel group 115. The reel support 111 is arranged on one side of the workbench 10. The reel shaft 113 is rotatably arranged on the reel support 111. One end of the reel shaft 113 is connected to the reel seat 112, and the other end of the reel shaft 113 is connected to the magnetic damper 114. The reel seat 112 is used to install the tape reel 500. The rotating wheel group 115 is arranged on the workbench 10, and the tape 501 of the tape reel 500 passes through the rotating wheel group 115. The rotating wheel group 115 consists of three rotating wheels, which are distributed in a triangle, and one rotating wheel is at a vertex of the triangle.

[0057] After the tape reel 500 is mounted on the reel seat 112 and fixed, the tape 501 can be pulled out from the tape reel 500 and the tape 501 can be passed through the rotating wheel set 115. The rotating wheel set 115 can flatten the tape 501 and reduce the pulling force on the tape 501 to prevent the tape 501 from being accidentally broken due to excessive force.

[0058] The magnetic damper 114 of the reel shaft 113 can increase the rotational inertia of the tape reel 500 to prevent the tape 501 from being entangled due to the rotation of the tape reel 500.

[0059] The adhesive pulling assembly 12 is used to pull the adhesive tape 501 of the adhesive tape reel 500 to the adhesive cutting station;

[0060] The glue drawing assembly 12 includes a glue drawing linear guide 121, a glue drawing chuck seat 122, a glue drawing chuck 123, a servo motor 124, a screw 125 and a screw seat 126, the screw seat 126 is arranged on the workbench 10, the servo motor 124 is fixed on the screw seat 126, and the drive shaft of the servo motor 124 is connected to the screw 125; the glue drawing linear guide 121 is arranged on the workbench 10, the glue drawing chuck seat 122 can reciprocate along the glue drawing linear guide 121, the glue drawing chuck seat 122 is movably connected to the screw 125 through a screw connector 127, and the glue drawing chuck 123 is arranged on the glue drawing chuck seat 122.

[0061] It should be noted that, in this embodiment, the glue pulling direction is the X-axis, the horizontal direction is perpendicular to the glue pulling direction is the Y-axis, and the vertical direction is the Z-axis, wherein the X-axis, the Y-axis and the Z-axis are perpendicular to each other.

[0062] The servo motor 124 is used to drive the screw rod 125 to rotate, so that the glue pulling chuck seat 122 can reciprocate along the glue pulling linear guide 121, which can ensure that the glue pulling chuck seat 122 moves more accurately, realize accurate cutting of the tape 501, and ensure the subsequent pasting effect.

[0063] The adhesive cutting assembly 13 is used to cut the adhesive tape 501 into adhesive tape segments 502 of appropriate sizes at the adhesive cutting station.

[0064] The rubber cutting assembly 13 includes a cutter cylinder 131, a cutter linear guide 132, a cutter sliding plate 133 and a cutter mounting plate 134. The cutter cylinder 131 and the cutter linear guide 132 are both arranged on the workbench 10. The movable part of the cutter cylinder 131 is connected to the cutter sliding plate 133. The cutter sliding plate 133 can reciprocate along the cutter linear guide 132. The cutter mounting plate 134 is arranged on the cutter sliding plate 133. A cutter 135 is provided on the cutter mounting plate 134. Preferably, the cutter 135 is a toothed cutter, which can conveniently cut the tape 501.

[0065] After the glue cutting action is completed, in order to facilitate the glue pulling component 12 to continue to perform the glue pulling action, the glue cutting component 13 is provided with a tape fixing component 14 on the side close to the unwinding component 11, and the tape fixing component 14 includes an adjusting base 141, and the adjusting base 141 is provided with a fixed pressure block 142 and a tape fixing cylinder mounting plate 143. The fixed pressure block 142 and the tape fixing cylinder mounting plate 143 can reciprocate along the conveying direction of the tape 501. The tape fixing cylinder mounting plate 143 is provided with a tape fixing cylinder 144, and the movable part of the tape fixing cylinder 144 is provided with a tape pressure strip 145. When the tape 501 needs to be cut, the movable part of the tape fixing cylinder 144 moves toward the fixed pressure block 142, so that the tape pressure strip 145 presses the tape 501 on the fixed pressure block 142, thereby fixing the tape 501. When the cutting is completed, the glue pulling chuck 123 of the glue pulling component 12 moves toward the tape fixing component 14 and clamps the end of the tape 501. Then, the glue pulling chuck 123 of the glue pulling component 12 moves away from the tape fixing component 14, thereby realizing the continuous supply of the tape 501.

[0066] The glue feeding mechanism 200 is used to remove the adhesive tape segment 502 from the adhesive placing mechanism 100 and paste it on the adhesive pasting position corresponding to the battery cell 3;

The gantry 400 is provided with a glue feeding bracket slide rail 401 and a glue feeding bracket driver. The glue feeding bracket slide rail 401 is arranged along the Y-axis direction. Driven by the glue feeding bracket driver, the glue feeding bracket 201 can reciprocate along the glue feeding bracket slide rail 401. The glue feeding bracket 201 is provided with a glue feeding lifting assembly. The two glue feeding arms 202 can move in the vertical direction, i.e., the Z-axis direction, through the glue feeding lifting assembly. Each glue feeding arm 202 is provided with a tape suction head 2021 at the end close to one end of the glue pressing mechanism. Each glue feeding arm 202 is provided with a glue sticking arm 203.

The glue sticking arm 203 is provided with a glue sticking roller 2031 at one end away from the glue feeding arm 202.

[0068] The glue feeding lifting assembly is provided with a glue feeding variable distance cylinder, and the two glue feeding arms 202 can be moved closer to or farther away from each other under the drive of the glue feeding variable distance cylinder. When it is necessary to absorb the tape segment 502, the glue feeding variable distance cylinder drives the two glue feeding arms 202 to move closer to each other to facilitate the absorption of the tape segment 502. After the tape segment 502 is absorbed and ready for glue application, the glue feeding variable distance cylinder drives the two glue feeding arms 202 to move away from each other so that the distance between the two glue feeding arms 202 is adapted to the width of the battery cell 600.

[0069] In order to realize the glue sticking action, each glue feeding support arm 202 is provided with a support arm driving cylinder 204 , and the movable part of each support arm driving cylinder 204 is connected to a glue sticking support arm 203 .

[0070] In order to facilitate sticking the adhesive tape to the adhesive sticking position at the corner of the rear end of the battery cell, a storage groove 2022 is provided at the end of the adhesive feeding support arm 202 , and the adhesive sticking roller 2031 can be stored in the storage groove 2022 .

[0071] Preferably, in order to facilitate the control of the glue application action, each glue feeding arm 202 has two tape suction heads 2021 , and the two tape suction heads 2021 are respectively arranged on both sides of the storage groove 2022 .

[0072] The glue feeding mechanism 200 moves the glue feeding arm 202 to the glue cutting station, and adsorbs the tape 501 located at the glue cutting station onto the tape suction head 2021 through the tape suction head 2021, and then the glue cutting component 13 cuts the tape 501 into tape segments 502 of appropriate sizes, and then the glue feeding mechanism 200 moves the glue feeding arm 202 to the glue sticking station for glue sticking.

[0073] When gluing, the glue feeding arm 202 moves with the tape segment 502 toward the tail end of the battery cell 600 and abuts against the tail end of the battery cell 600, and sticks one end of the tape segment 502 to the gluing position at the tail end of the battery cell 600. Then the tape suction head 2021 stops adsorption, and the arm driving cylinder drives the glue sticking arm 203 to move toward the battery cell 600. The glue sticking arm 203 moves the glue sticking roller 2031 out of the storage groove 2022, bends the tape segment 502 and sticks the remaining part of the tape segment 502 to the side of the battery cell 600 through the glue sticking roller 2031, thereby completing the gluing action of the battery cell 600.

[0074] The glue pressing mechanism 300 includes a glue pressing follower bracket 301 and two glue pressing arms 302.

A reset elastic member 303 is provided between each glue pressing arm 302 and the glue pressing follower bracket 301. When the glue feeding mechanism 200 is pasting the adhesive tape section 502, the glue feeding mechanism 200 drives the two glue pressing arms 302 to move toward the glue pressing follower bracket 301, and the insulating film 601 pre-pasted on the battery cell 600 is smoothed and shaped by the glue pressing roller 3021.

[0075] In order to make the movement of the glue pressing arm 302 more stable and reliable, the glue pressing follower bracket 301 is provided with a bracket slide rail 3011, and each glue pressing arm 302 is provided with an arm slider 3022, and the glue pressing arm 302 reciprocates along the bracket slide rail 3011 through the arm slider 3022.

[0076] A glue pressing station is formed between the two glue pressing arms 302 of the glue pressing mechanism 300, and the battery cell 600 with the insulating film 601 pasted is transported to the glue pressing station through the conveying mechanism. When pasting glue, the glue feeding arm 202 moves with the tape segment 502 to the tail end of the battery cell 600. In this process, until it abuts against the tail end of the battery cell 600, one end of the tape segment 502 is pasted on the glue pasting position at the tail end of the battery cell 600, and then the arm driving cylinder drives the glue pasting arm 203 to move toward the battery cell 600, and the end of the glue pasting arm 203 immediately abuts against the end of the glue pressing arm 302, and pushes the glue pressing arm 302 toward the head end of the battery cell 600. At this time, the glue pressing arm is set The glue pressing roller 3021 on 302 can first smooth out and shape the insulating film 601 on both sides of the battery cell 600. At the same time, the glue sticking arm 203 drives the glue sticking roller 2031 to move out of the storage groove 2022, bend the tape segment 502 and stick the remaining part of the tape segment 502 to the side of the battery cell 600 whose insulating film 601 has been flattened by the glue sticking roller 2031, that is, the gluing action of the battery cell 600 is completed. Since the glue pressing roller 3021 on the glue pressing arm 302 has smoothed and shaped the insulating film 601, when the tape segment 502 is stuck, it can prevent the insulating film 601 from becoming loose or even wrinkled due to force.

[0077] From the above description, it can be seen that the beneficial effect of the utility model is that it provides a tape pasting device, which can flatten and shape the insulating film that has been pasted on the battery cell in advance when pasting the tape segment on the battery cell, effectively avoiding the situation where the insulating film becomes loose or even wrinkled due to force when pasting the tape segment, greatly reducing the difficulty of the battery cell shelling process, thereby ensuring the quality and safety of the battery.

[0078] It is easy for those skilled in the art to understand that the above-mentioned implementation modes can be freely combined and superimposed without conflict.
