Description

Technical Field

[0001] This utility model relates to the field of lithium battery technology, and in particular to an electrode cutting and adhesive application mechanism with multiple adhesive application stations. Background Technology

[0002] In the manufacturing process of lithium batteries, cutting tape and corner protection tape need to be applied to the electrodes before winding. During winding, stop tape is applied. The cutting tape is applied at the cut position of the electrode, and the corner protection tape is applied at the corner of the electrode inside the bare cell. These tapes protect the structure at the cut and corner points, preventing breakage and improving battery safety, stability, and lifespan. In existing winding machines, the processes of applying cutting tape and corner protection tape are separated. The electrode is cut and tape is applied using an electrode cutting mechanism, and then corner protection tape is applied using a separate tape-applying mechanism. This separation requires the winding machine to stop or slow down twice to apply the cutting and corner protection tapes separately, resulting in insufficient overall process efficiency and difficulty in ensuring accurate tape application.

[0037] The specific embodiments of this utility model are described with reference to the accompanying drawings.

[0038] refer to Figure 1The figure shows a three-dimensional structural diagram of an electrode cutting and adhesive application mechanism with multiple adhesive application stations. A cutting and adhesive application device 101, a first corner adhesive application device 102, and a second corner adhesive application device 103 are arranged sequentially along the electrode conveyor path. The cutting and adhesive application device 101 is used to cut the electrode and apply cutting adhesive. The first corner adhesive application device 102 and the second corner adhesive application device 103 are used to apply first corner protective adhesive and second corner protective adhesive, respectively.

[0039] refer to Figures 1 to 7 An electrode cutting and adhesive application mechanism with multiple adhesive application stations includes a cutting and adhesive application device 101, a first corner adhesive application device 102, and a second corner adhesive application device 103 arranged sequentially along the electrode conveyor path. The cutting and adhesive application device 101 has a front clamping roller assembly 201 and a rear clamping assembly 202 arranged on the front and rear sides of the electrode conveyor path to clamp and position the electrode. During the process of clamping the electrode by the front clamping roller assembly 201 and the rear clamping assembly 202, the cutting and adhesive application device 101 cuts the electrode and applies cutting adhesive to the A and B sides of the electrode respectively. The first corner adhesive application device 102 applies first corner protective adhesive to the A and B sides of the electrode respectively. The second corner adhesive application device 103 applies second corner protective adhesive to the A and B sides of the electrode respectively.

[0040] The electrode cutting and adhesive application mechanism of this application with multiple adhesive application stations cuts the electrode and applies cutting adhesive through the cutting and adhesive application device 101, and applies first corner protective adhesive and second corner protective adhesive through the first corner adhesive application device 102 and the second corner adhesive application device 103 respectively. The cutting adhesive and the two corner protective adhesives can be applied simultaneously with one electrode stop, which shortens the adhesive application time, improves production efficiency, and ensures the accuracy of the adhesive application position through component linkage.

[0041] In order to complete the cutting of the electrode sheet, in this embodiment, reference is made to... Figures 1 to 5 The cutting and applying device includes a cutting blade assembly 1, a cutting and applying suction cup assembly 2, a cutting and applying adhesive preparation assembly 401, and a cutting transverse movement assembly 3. The cutting blade assembly 1 and the cutting and applying suction cup assembly 2 are movably arranged between the cutting position 304 and the first adhesive preparation position 301 through the cutting transverse movement assembly 3. The cutting and applying adhesive preparation assembly 401 is arranged in the first adhesive preparation position 301. The cutting and applying suction cup assembly 2 receives the cutting adhesive in the first adhesive preparation position 301 through the cutting and applying adhesive preparation assembly 401, and applies the cutting adhesive to the cutting position of the electrode sheet in the cutting position 304.

[0042] Understandably, with this setup, the cutting blade assembly 1 and the cutting adhesive suction cup assembly 2 are located between the front clamping roller assembly 201 and the rear clamping assembly 202. The cutting adhesive suction cup assembly 2 completes the preparation of the cutting adhesive at the first adhesive preparation position 301. The front clamping roller assembly 201 and the rear clamping assembly 202 clamp the electrode sheet. After the cutting blade of the cutting blade assembly 1 cuts the electrode sheet, the cutting lateral movement assembly 3 will drive the cutting blade assembly 1 and the cutting adhesive suction cup assembly 2 to move laterally, so that the cutting adhesive suction cup assembly 2 moves from the first adhesive preparation position to the cutting position 304. The cutting adhesive suction cup assembly 2 applies the cutting adhesive to the cutting position of the electrode sheet, completing the cutting of the electrode sheet and the application of the cutting adhesive.

[0043] In order to apply the cutting adhesive, in this embodiment, refer to Figures 1 to 5 The cutting and applying suction cup assembly 2 includes a first suction cup 21 and a second suction cup 22. The first suction cup 21 and the second suction cup 22 are symmetrically arranged on the outer side of the A and B sides of the electrode. The first suction cup 21 and the second suction cup 22 are connected to the cutting and applying adhesive correction drive assembly 4 through the first bracket 23.

[0044] Understandably, with this configuration, the first suction cup 21 and the second suction cup 22 of the cutting and adhesive suction cup assembly 2 are both positioned perpendicular to the electrode's conveying direction. The first suction cup 21 faces the A side of the electrode, and the second suction cup 22 faces the B side of the electrode. After the electrode is cut, the first suction cup 21 and the second suction cup 22 are moved to the cutting position 304 by the cutting transverse moving assembly 3. The first suction cup 21 and the second suction cup 22 are pressed against the cutting position of the electrode by their respective cylinders, so that the cutting adhesive on the first suction cup 21 and the second suction cup 22 is simultaneously adhered to the electrode, and pressure is maintained for a period of time so that the cutting adhesive can be stably adhered to the cutting position of the electrode.

[0045] In order to drive the cutting blade assembly 1 and the cutting adhesive suction cup assembly 2 to move between the cutting position 304 and the first adhesive preparation position 301, in this embodiment, reference is made to... Figures 1 to 5 The cutting transverse component 3 includes a cutting transverse seat 31, a cutting transverse guide rail 32, and a cutting transverse cylinder 33. The cutting blade assembly 1 and the cutting adhesive suction cup assembly 2 are mounted on the cutting transverse seat 31, and the cutting transverse seat 31 is mounted on the cutting transverse guide rail 32. The cutting transverse guide rail 32 is set parallel to the electrode tape path. The cutting transverse cylinder 33 drives the cutting transverse seat 31, the cutting blade assembly 1, and the cutting adhesive suction cup assembly 2 to move along the cutting transverse guide rail 32.

[0046] Understandably, with this setup, both the cutting blade assembly 1 and the cutting adhesive suction cup assembly 2 are mounted on the cutting transverse support 31. The cutting transverse cylinder 33 drives the cutting transverse support 31 to move along the cutting transverse guide rail 32, which is set along the electrode conveyor path. This drives the cutting blade assembly 1 and the cutting adhesive suction cup assembly 2 to move between the cutting position 304 and the first adhesive preparation position 301, completing the cutting of the electrode and the application of the cutting adhesive.

[0047] To ensure precise application of the cutting adhesive, in this embodiment, refer to Figures 1 to 4 The electrode cutting and adhesive application mechanism with multiple adhesive application stations also includes a corner adhesive application and correction drive assembly 8. The corner adhesive application and correction drive assembly 8 includes a first correction motor 81, a first guide rod 82, and a correction mounting plate 83. The first correction motor 81 is connected to the correction mounting plate 83 through the first guide rod 82. The first corner adhesive application assembly 5 of the first corner adhesive application device 102 and the second corner adhesive application assembly 6 of the second corner adhesive application device 103 are mounted on the correction mounting plate 83. The first correction motor 81 drives the first corner adhesive application assembly 5 and the second corner adhesive application assembly 6 to move along the direction perpendicular to the electrode tape travel path.

[0048] It should be further explained that the cutting and adhesive correction drive assembly 4 includes a second correction motor 41 and a second guide rod 42. The second guide rod 42 is mounted on the cutting transverse seat 31 and is fixedly connected to the first bracket 23. The second guide rod 42 is connected to the screw drive end of the second correction motor 41 through the transmission seat 43. The second correction motor 41 drives the first suction cup 21 and the second suction cup 22 to move along the second guide rod 42 to adjust the adhesive application position.

[0049] Understandably, with this setup, a deviation correction detection component 203 is positioned in front of the front clamping roller assembly 201. The deviation correction detection component 203 detects the position of the electrode tape via a sensor. The signal detected by the deviation correction detection component 203 is transmitted to the cutting and applying adhesive deviation correction drive assembly 4 and the corner applying adhesive deviation correction drive assembly 8. The first deviation correction motor 81 of the corner applying adhesive deviation correction drive assembly 8 controls the travel of the deviation correction mounting plate 83 according to the signal. The second deviation correction motor 41 of the cutting and applying adhesive deviation correction drive assembly 4 controls the travel of the first bracket 23 according to the signal, thereby adjusting the position of the cutting and applying adhesive suction cup assembly 2, the first corner applying adhesive assembly 5, and the second corner applying adhesive assembly 6, correcting the position of the cutting adhesive and corner protective adhesive to ensure the accuracy of the adhesive application position.

[0050] To ensure precise application of the first and second corner protective adhesives, in this embodiment, reference is made to... Figures 1 to 4The alignment mounting plate 83 is provided with a corner adhesive application transverse guide rail 75. The corner adhesive application transverse guide rail 75 is provided with a first transverse seat 71 and a second transverse seat 73. The first corner adhesive application component 5 is installed on the first transverse seat 71, and the second corner adhesive application component 6 is installed on the second transverse seat 73. The alignment mounting plate 83 is provided with a first transverse motor 72 and a second transverse motor 74. The first transverse motor 72 and the second transverse motor 74 are respectively connected to the first transverse seat 71 and the second transverse seat 73 for transmission. The first transverse motor 72 drives the first transverse seat 71 and the first corner adhesive application component 5 to move along the corner adhesive application transverse guide rail 75, and the second transverse motor 74 drives the second transverse seat 73 and the second corner adhesive application component 6 to move along the corner adhesive application transverse guide rail 75.

[0051] Understandably, with this setup, the required placement of the corner protective adhesive varies depending on the electrode size. The first transverse motor 72 and the second transverse motor 74, through preset parameters, drive the first transverse seat 71 and the second transverse seat 73 to the specified positions, respectively, so that the first corner adhesive application component 5 and the second corner adhesive application component 6 can move to the corresponding adhesive application positions as required, thereby improving compatibility.

[0052] In order to attach two first corner protective adhesives to sides A and B of the electrode, in this embodiment, refer to Figure 6 The first corner adhesive assembly 5 includes a third suction cup 51 and a fourth suction cup 52. The third suction cup 51 and the fourth suction cup 52 are symmetrically arranged on the outer side of the A and B sides of the electrode sheet. The third suction cup 51 and the fourth suction cup 52 are mounted on the first transverse support 71 through the corresponding second bracket 53.

[0053] Understandably, with this setup, both the third suction cup 51 and the fourth suction cup 52 are perpendicular to the electrode's conveying direction. The third suction cup 51 faces side A of the electrode, and the fourth suction cup 52 faces side B of the electrode. After the third suction cup 51 and the fourth suction cup 52 complete the preparation of the first corner protective adhesive at the second adhesive preparation position 302, they are moved to the corresponding adhesive application position by the first transverse motor 72. The third suction cup 51 and the fourth suction cup 52 are pressed against the electrode by their respective cylinders, so that the first corner protective adhesive on the third suction cup 51 and the fourth suction cup 52 is simultaneously adhered to the electrode, and pressure is maintained for a period of time to ensure that the first corner protective adhesive is stably adhered to the electrode.

[0054] In order to attach two second corner protective adhesives to sides A and B of the electrode, in this embodiment, refer to Figure 6 The second corner adhesive assembly 6 includes a fifth suction cup 61 and a sixth suction cup 62. The fifth suction cup 61 and the sixth suction cup 62 are symmetrically arranged on the outer side of the A and B sides of the electrode sheet. The fifth suction cup 61 and the sixth suction cup 62 are mounted on the second transverse support 73 through the corresponding third bracket 63.

[0055] Understandably, with this setup, both the fifth suction cup 61 and the sixth suction cup 62 are perpendicular to the electrode's conveying direction. The fifth suction cup 61 faces side A of the electrode, and the sixth suction cup 62 faces side B of the electrode. After the fifth suction cup 61 and the sixth suction cup 62 complete the preparation of the second corner protective adhesive at the third adhesive preparation position 303, they are moved to the corresponding adhesive application position by the second transverse motor 74. The fifth suction cup 61 and the sixth suction cup 62 are pressed against the electrode by their respective cylinders, so that the second corner protective adhesive on the fifth suction cup 61 and the sixth suction cup 62 is simultaneously adhered to the electrode, and pressure is maintained for a period of time to ensure that the second corner protective adhesive is stably adhered to the electrode.

[0056] In order to prepare the cutting adhesive and corner protection adhesive, in this embodiment, refer to Figures 1 to 7 The electrode cutting and adhesive application mechanism with multiple adhesive application stations also includes a back plate 9. The cutting and adhesive application preparation component 401 of the cutting and adhesive application device, the first corner adhesive application preparation component 402 of the first corner adhesive application device 102, and the second corner adhesive application preparation component 403 of the second corner adhesive application device 103 are mounted on the back plate 9. The cutting and adhesive application preparation component 401, the first corner adhesive application preparation component 402, and the second corner adhesive application preparation component all include a mounting frame 91. The mounting frame 91 is fixedly connected to the back plate 9. The mounting frame 91 is provided with two material trays 92. The two material trays 92 are guided by multiple material rollers 93 to two adhesive tapes to the cutting position 305. The cutting position 305 is provided with a cutting seat 94. The mounting frame 91 is provided with two sets of adhesive pulling modules 98. The adhesive pulling modules 98 are provided with adhesive pulling rollers 99 for pulling adhesive tapes.

[0057] Understandably, with this setup, the cutting and applying adhesive preparation component 401, the first corner adhesive preparation component 402, and the second corner adhesive preparation component 403 are located at the first preparation position 301, the second preparation position 302, and the third preparation position 303, respectively, to perform the preparation of cutting adhesive, first corner protective adhesive, and second corner protective adhesive. The cutting and applying adhesive preparation component 401, the first corner adhesive preparation component 402, and the second corner adhesive preparation component 403 are all installed together on the back plate 9, so that the preparation position can be kept stable. The adhesive pulling module 98 drives the adhesive pulling roller 99 in the direction of the vertical electrode tape, so that the adhesive pulling roller 99 can pull out the tape of a specified length from the cutting position 305 and be attracted by the corresponding suction cup. Then, the tape is cut by the cutting seat 94, thus completing the preparation of adhesive.

[0058] In order to cut the cutting adhesive and corner protection adhesive during the adhesive preparation process, in this embodiment, reference is made to... Figure 7 Two cutting blades 95 are provided on the cutting base 94. The two cutting blades 95 are symmetrically arranged on both sides of the cutting base 94. A suction plate 96 is provided on the outside of the cutting blade 95. The suction plate 96 is movably mounted on the mounting frame 91 by the cutting cylinder 97.

[0059] Understandably, with this setup, two tapes need to be cut simultaneously during the preparation process at each tape preparation station. The two tapes at the tape cutting station 305 are not far apart. The tape cutting blade 95 remains stationary while the suction plate 96 moves. After the suction cup holds the tape, the tape cutting cylinder 97 drives the suction plate 96 to move towards the tape cutting blade 95, so that the tape cutting blade 95 contacts and cuts the tape.

[0060] The working process of this application is as follows: After the electrode sheet is stopped at the designated position by the anti-vibration roller assembly 204, the front clamping roller assembly 201 and the rear clamping assembly 202 clamp the electrode sheet. The cutting blade assembly 1 approaches the electrode sheet and cuts it. The cutting adhesive correction drive assembly 4 and the corner adhesive correction drive assembly 8 correct the deviation based on the signal transmitted by the correction detection assembly 203, and adjust the adhesive application positions of the cutting adhesive and the first corner protective adhesive and the second corner protective adhesive. The cutting transverse movement assembly 3 drives the cutting adhesive suction cup assembly 2 to move to the cutting position 304. The first transverse movement motor 72 and the second transverse movement motor 74 respectively drive the first corner adhesive application assembly 5 and the second corner adhesive application assembly 6 to translate to the corresponding adhesive application positions. Under the drive of their respective cylinders, the first suction cup 21 and the second suction cup 22, the third suction cup 51 and the fourth suction cup 52, the fifth suction cup 61 and the sixth suction cup 62 cut the cutting adhesive and the first corner protective adhesive. Corner protective adhesive and second corner protective adhesive are respectively pasted onto the electrode sheet and separated after being pressed for a period of time. Then, the front clamping roller assembly 201 and the rear clamping assembly 202 release the electrode sheet, and the electrode sheet proceeds to normal conveyor belt operation. The cutting adhesive suction cup assembly 2, the first corner adhesive assembly 5 and the second corner adhesive assembly 6 move to the first adhesive preparation position 301, the second adhesive preparation position 302 and the third adhesive preparation position 303 respectively. The cutting adhesive, the first corner protective adhesive and the second corner protective adhesive are prepared by the cutting adhesive preparation assembly 401, the first corner adhesive preparation assembly 402 and the second corner adhesive preparation assembly 403. After the adhesive preparation is completed, the cutting adhesive suction cup assembly 2, the first corner adhesive assembly 5 and the second corner adhesive assembly 6 correct their positions according to the signals of each correction detection assembly 203 and move laterally to the corresponding adhesive application position. After the electrode sheet stops conveying, the next adhesive application is performed.

[0061] The above does not limit the technical scope of this utility model. Any modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of this utility model shall still fall within the scope of the technical solution of this utility model.
