Therefore, the following detailed implementation manners and the accompanying drawings are only exemplary descriptions of the technical solution of the present invention, and should not be regarded as the whole of the present invention or as a limitation or restriction on the technical solution of the present invention.

[0035] As Figure 1-3 shown, as a square lithium battery cell online taping machine of the present invention, it includes a taping mechanism 20, and the taping mechanism 20 is arranged on the production line 10;

[0036] The taping mechanism 20 includes a frame 21,

[0037] a product lifting component 22 for transporting products on the production line 10,

[0038] a tape feeding component 23 for tape conveying,

[0039] and a transplanting and pasting component 24 for transporting the tape and pasting it onto the product;

[0040] The product lifting assembly 22, the tape feeding assembly 23 and the transplanting and gluing assembly 24 are all arranged on the frame 21;

[0041] like Figure 3 As shown, the transplanting glue sticking assembly 24 includes a first cylinder 241, a sliding adjustment seat 242, a sliding connecting plate 243, a fixed plate 244 and a glue sticking part 245. The first cylinder 241 is fixed on the frame 21. The sliding adjustment seat 242 is transmission-connected on the output shaft of the first cylinder 241. The sliding adjustment seat 242 is provided with a sliding connecting plate 243 with adjustable position. The sliding connecting plate 243 is fixed with a fixed plate 244. The fixed plate 244 is provided with a rotatable and adjustable glue sticking part 245. The glue sticking part 245 transfers the tape and sticks it to the product.

[0042] Specifically, the first cylinder 241 controls the sliding adjustment seat 242 to move, which can move the glue sticking part 245. The glue sticking part 245 can transport the tape on the tape feeding assembly 23 to the square lithium battery cell for bonding operation. The sliding connecting plate 243 is located at different positions on the sliding adjustment seat 242, and can adjust the position of the glue sticking part 245 relative to the square lithium battery cell. This structural setting, on the one hand, can quickly and accurately perform glue sticking operations on the square lithium battery cell, and on the other hand, the position of the glue sticking part 245 can be adjusted in multiple directions, making the equipment more applicable.

[0043] The production line 10 is provided with a tray 30 for placing square lithium battery cells. The product lifting component 22 clamps and lifts the square lithium battery cells on the tray 30, and the transplanting and gluing component 24 transfers the tape on the tape loading component 23 and sticks it to the square lithium battery cells to complete the gluing operation of the square lithium battery cells. This method is directly applied to the production line 10, has a compact size, does not occupy additional production space, has high gluing efficiency, is more accurate in gluing position, and has better later use effect of the lithium battery cells.

[0044] like Figure 4 As shown, the gluing part 245 includes a rotating cylinder 2451, a second cylinder 2453 and a gluing head 2458. The rotating cylinder 2451 is fixed on the fixed plate 244. The output shaft of the rotating cylinder 2451 is connected to the first fixed seat 2452 in a transmission manner. The first fixed seat 2452 is fixed with the second cylinder 2453. The output shaft of the second cylinder 2453 is connected to the right-angle connecting seat 2454 in a transmission manner. The right-angle connecting seat 2454 is fixed with the second fixed seat 2455. The second fixed seat 2455 is symmetrically provided with a position-adjustable gluing head 2458.

[0045] Specifically, the rotating cylinder 2451 can drive the second cylinder 2453 and the right-angle connecting seat 2454, the second fixed seat 2455 and the gluing head 2458 to rotate as a whole, so that the gluing head 2458 can be adjusted at multiple angles, and can perform gluing operations on various different types of square lithium battery cells, with a wider range of applications; the second cylinder 2453 can move the second fixed seat 2455 and the gluing head 2458 in a single direction, which can further expand the movement range of the gluing head 2458, and has a wider range of applications.

[0046] like Figure 4-5 As shown, a third cylinder 2457 is fixed on the second fixed seat 2455 , and a sliding connection block 2456 is transmission-connected to the output shaft of the third cylinder 2457 . The sliding connection block 2456 is slidingly connected to the second fixed seat 2455 , and the sliding connection block 2456 is fixedly connected to the glue head 2458 .

[0047] Specifically, the third cylinder 2457 drives the sliding connection block 2456 to move, thereby driving the gluing head 2458 on the sliding connection block 2456 to move. The tape is located between the two gluing heads 2458. The two gluing heads 2458 squeeze the tape to fit it onto the square lithium battery cell, which can make the tape fit more stably.

[0048] like Figure 5 As shown, an interference block 2459 is provided between the two adhesive heads 2458, and the interference block 2459 is fixed on the second fixing seat 2455. Through the setting of the interference block 2459, on the one hand, when the tape is placed, the tape can be laid more smoothly without wrinkles. On the other hand, during the process of tape bonding, the interference block 2459 will squeeze the tape and press it onto the side wall of the square lithium battery cell, further improving the bonding stability of the tape.

[0049] like Figure 5 As shown, the corners of the opposite surfaces of the gluing heads 2458 are arc-shaped structures, and the two gluing heads 2458 are made of elastic material. This structural setting allows the gluing heads 2458 to move more smoothly to the square lithium battery cells during the process of pressing the tape to the square lithium battery cells, and at the same time, the tape can be pressed to ensure a stable tape laminating position.

[0050] like Figure 5 As shown, a negative pressure pump 2460 is provided on the gluing head 2458 and the resistance block 2459, and a through hole connected to the air inlet pipe of the negative pressure pump 2460 is opened in the gluing head 2458 and the resistance block 2459. Through this structural setting, the tape can be quickly and accurately sucked onto the gluing head 2458 and the resistance block 2459, which facilitates the limited transfer operation of the tape.

[0051] like Figure 6As shown in the figure, the tape feeding assembly 23 includes a mounting plate 231, a tape roller 232, a tape guiding roller 233, a first limiting frame 234, a second limiting frame 235, a fourth cylinder 236, a fifth cylinder 237 and a cutting knife 238. The mounting plate 231 is fixed on the frame 21. There is a tape roller 232 for storing the tape on the mounting plate 231. There is a tape guiding roller 233 on the mounting plate 231 for changing the tape conveying direction. A first limiting frame 234 and a second limiting frame 235 are arranged on the mounting plate 231 on the output side of the tape guiding roller 233. The first limiting frame 234 is fixed on the mounting plate 231. The second limiting frame 235 is slidably arranged on the mounting plate 231. The second limiting frame 235 clamps and drags the tape to move. A fourth cylinder 236 is connected to the second limiting frame 235. The fourth cylinder 236 is fixed on the mounting plate 231. The fourth cylinder 236 controls the movement of the second limiting frame 235. A cutting knife 238 is arranged between the first limiting frame 234 and the second limiting frame 235 on the mounting plate 231. The cutting knife 238 is arranged on the side close to the first limiting frame 234. The cutting knife 238 is arranged on the fifth cylinder 237. The fifth cylinder 237 controls the movement of the cutting knife 238 to cut the tape.

[0052] Specifically, the roll of tape is placed on the tape roller 232. The tape passes through the tape guiding roller 233 and is arranged through the first limiting frame 234 and the second limiting frame 235. The tape guiding roller 233 maintains the tension of the tape. The fourth cylinder 236 controls the second limiting frame 235. The second limiting frame 235 clamps the tape and moves it, so that the tape moves from the position close to the first limiting frame 234 to the position far from the first limiting frame 234. When the length of the tape is appropriate, the fifth cylinder 237 controls the cutting knife 238 to cut the tape, so that the tape can be cut into sections for sticking to the square lithium battery cells; after the cutting knife 238 cuts the tape, a part of the tape extends out of the first limiting frame 234. The fourth cylinder 236 controls the second limiting frame 235 to move to the position of the tape extending out of the first limiting frame 234 and clamps the tape, so as to drive the tape to move.

[0053] As Figure 6 shown in the figure, a support block is slidably arranged inside the first limiting frame 234. A support spring connecting the bottom of the first limiting frame 234 is arranged at the bottom of the support block. During the process of keeping the tape position stable on the first limiting frame 234, the tape on the first limiting frame 234 can also move. An elastic gasket is slidably arranged inside the second limiting frame 235. A hydraulic telescopic rod for driving the elastic gasket to move is arranged in the second limiting frame 235. The movement of the elastic gasket is controlled by the hydraulic telescopic rod. When the tape is squeezed, the position of the tape on the second limiting frame 235 can be restricted.

[0054] As Figure 7-8As shown, the product lifting assembly 22 includes a limit plate 221, an eighth cylinder 222, a circular frame 223, a clamping head 229, a seventh cylinder 2210 and a sliding limit seat 2211. The limit plate 221 is fixed on the frame 21. The eighth cylinder 222 is bolted to the limit plate 221. The output shaft of the eighth cylinder 222 is transmission-connected with the circular frame 223. Sliding limit seats 2211 are symmetrically provided on both sides of the bottom of the circular frame 223. The sliding limit seat 2211 is slidingly connected with the clamping head 229 for clamping the product. The seventh cylinder 2210 for driving the clamping head 229 to move is fixed on the circular frame 223.

[0055] Specifically, the eighth cylinder 222 is used to control the movement of the circular frame 223 and the equipment on the circular frame 223. The clamping head 229 on the circular frame 223 clamps and limits the square lithium battery cells, thereby performing a lifting operation on the square lithium battery cells; the sliding limit seat 2211 is slidably connected to the clamping head 229 of the clamping product, and the seventh cylinder 2210 that drives the clamping head 229 to move is fixed on the circular frame 223, so that the position of the clamping head 229 can be adjusted, which is suitable for clamping operations of different types of square lithium battery cells, and can also perform clamping and limiting operations on square lithium battery cells at different parts of the production line 10.

[0056] like Figure 7-8 As shown, a sixth cylinder 224 is symmetrically provided on the circular frame 223, and a first pressing plate 225 is transmission-connected to the output shaft of the sixth cylinder 224. The first pressing plate 225 is located below the circular frame 223;

[0057] The frame 21 is symmetrically provided with sliding rods 228, and the sliding rods 228 are provided with a placement plate 226, and a second pressing plate 227 is fixed on the placement plate 226. The first pressing plate 225 and the second pressing plate 227 clamp the product to limit the product position and correct the product deformation.

[0058] Specifically, the eighth cylinder 222 controls the clamping head 229 to clamp the square lithium battery cell for lifting, the seventh cylinder 2210 controls the horizontal movement of the clamping head 229 to move the square lithium battery cell onto the second pressing plate 227, and the sixth cylinder 224 controls the first pressing plate 225 to move downward, so that the first pressing plate 225 and the second pressing plate 227 clamp and limit the position of the square lithium battery cell, preventing the square lithium battery cell from moving during the gluing process, making the gluing process more stable and the gluing effect better.

[0059] The technical scope of the present invention is not limited to the contents of the above description.
