The described embodiments are some, but not all, of the embodiments of the present utility model.

[0029] Therefore, the following detailed description of the embodiments of the present utility model provided in the drawings is not intended to limit the scope of the claimed present utility model, but merely represents selected embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts fall within the scope of protection of the present utility model.

[0030] In the following embodiments, Figure 1 Taking the coordinate system in

[0031] as the standard, the direction indicated by the arrow of the X-axis is set as right, the direction indicated by the arrow of the Y-axis is set as front, and the direction indicated by the arrow of the Z-axis is set as up.

[0032] As Figures 1 to 3 shown, in this embodiment, a rotary adhesive pasting device includes: a mounting plate 100, which is respectively provided with mounting parts at opposite ends, and the two mounting parts are respectively arranged opposite to the glue discharging station and the welding mark station; two adhesive pasting mechanisms 200, each adhesive pasting mechanism 200 includes a variable pitch component 210 and a plurality of glue sucking components 220 for lifting and adsorbing the cut glue tape. The variable pitch component 210 includes a positioning plate 211 and a variable pitch cylinder 212. The positioning plate 211 is installed on the mounting plate 100, the variable pitch cylinder 212 is installed on the positioning plate 211, and the output end of the variable pitch cylinder 212 is connected to the glue sucking component 220 to drive the plurality of glue sucking components 220 to vary the pitch to match the width required for welding marks after adsorbing the adhesive tape; and a driver 300, whose output end is connected to the mounting plate 100, for driving the mounting plate 100 to rotate so that each adhesive pasting mechanism 200 sequentially surrounds the glue discharging station and the welding mark station.

[0033] Specifically, mounting parts are respectively arranged at the front and rear ends of the mounting plate 100. In the initial state, the front mounting part is located above the glue discharging station, and the rear mounting part is located on the welding mark station. The two adhesive pasting mechanisms 200 are respectively connected to the mounting parts. The variable pitch component 210 is used to vary the pitch of the plurality of glue sucking components 220. The manner in which the variable pitch cylinder 212 drives the glue sucking component 220 to vary the pitch is known to those skilled in the art and can be realized, and will not be described in detail in this embodiment. The glue sucking component 220 is used to lift and adsorb the cut glue tape on the glue discharging station. The driver 300 is installed on the frame and is located below the mounting plate 100.

[0034] It should be noted that two sets of glue - applying mechanisms 200 are used in this rotary glue - applying mechanism 200. The two glue - applying mechanisms 200 are respectively set as the first glue - applying mechanism 200 and the second glue - applying mechanism 200. In the initial state, the first glue - applying mechanism 200 is located at the glue - discharging station on the front side, and the second glue - applying mechanism 200 is located at the welding - mark station on the rear side. During operation, the glue - sucking assembly 220 in the first glue - applying mechanism 200 descends to suck the adhesive tape and then returns to its original position. Then, the drive 300 drives the mounting plate 100 to rotate. At the same time, the pitch - changing cylinder 212 in the first glue - applying mechanism 200 changes the pitch, so that the distance between the glue - sucking assemblies 220 changes, thus matching the width required for welding marks. Until the drive 300 rotates 180°, the first glue - applying mechanism 200 reaches the welding - mark station and can descend for welding marks and then return to its original position. It can be understood that when the first glue - applying mechanism 200 rotates 180° to reach the welding - mark station for welding marks, the second glue - applying mechanism 200 rotates 180° to reach the glue - discharging station for taking glue. In this way, compared with the traditional linear - motion glue - applying mechanism 200, it can realize the simultaneous operation of glue - applying and glue - preparation actions, which can greatly improve the glue - applying efficiency and thus improve the single - machine efficiency of the machine.

[0035] Embodiment 2

[0036] This embodiment is a further implementation manner of Embodiment 1. In this embodiment, each glue - sucking assembly 220 includes a lifting unit 221 and a sucking unit 222. The lifting unit 221 is connected to the pitch - changing assembly 210, and the output end of the lifting unit 221 is connected to the sucking unit 222.

[0037] Specifically, the lifting unit 221 drives the sucking unit 222 to lift, so as to facilitate the glue - sucking unit to descend and suck the adhesive tape in the glue - discharging station.

[0038] In some embodiments, the lifting unit 221 includes a plate body 2211 and a lifting cylinder 2212. The output end of the pitch - changing cylinder 212 is connected to the plate body 2211, and the output end of the lifting cylinder 2212 is connected to the sucking unit 222.

[0039] Specifically, the pitch - changing cylinder 212 drives the plate body 2211 to move horizontally, so as to adjust the distance between multiple plate bodies 2211 and change the distance between the sucking units 222. The way that the lifting cylinder 2212 drives the sucking unit 222 to lift is known to those skilled in the art and can be realized, so it will not be described in detail in this embodiment.

[0040] In some embodiments, the suction unit 222 includes a vacuum generator 2222, a support 2221, and a suction cup 2223. The output end of the lifting unit 221 is drivingly connected to the support 2221. The vacuum generator 2222 is installed on the support 2221. The suction cup 2223 is connected to the vacuum generator 2222. The vacuum generator 2222 drives the suction cup 2223 to adsorb the adhesive tape.

[0041] Specifically, the output end of the lifting cylinder 2212 is connected to the support 2221 to drive the suction cup 2223 connected to the support 2221 to rise or fall. The suction cup 2223 is used to adsorb the adhesive tape. At the glue discharging station, the suction cup 2223 can be disposed directly above the glue discharging station. At the soldering mark station, the suction cup 2223 can be disposed directly above the welding position. The manner in which the vacuum generator 2222 drives the suction cup 2223 to generate a vacuum is known to those skilled in the art and can be implemented, and will not be described in detail in this embodiment.

[0042] In some embodiments, a cross plate 213 is provided at one end of the positioning plate 211 close to the mounting plate 100. The cross plate 213 is connected to the mounting plate 100. Two vertical plates 214 are arranged in parallel on the cross plate 213, and the two vertical plates 214 are connected to the positioning plate 211. The cross-sectional shape of the vertical plate 214 is set as a right trapezoid.

[0043] Specifically, the cross plate 213 and the mounting plate 100 can be connected by, but are not limited to, screwing. By setting the cross-sectional area of the vertical plate 214 as a right trapezoid and the right-angle side close to the positioning plate 211, it is convenient to form a more stable connection relationship. The cross plate 213 and the two vertical plates 214 form a support seat. By providing a support seat between the positioning plate 211 and the mounting plate 100, the connection between the positioning plate 211 and the mounting plate 100 is made more stable, and it is convenient to fixedly install the tape pasting mechanism 200 on the mounting plate 100. Thereby effectively increasing the practicability of the device. Preventing it from detaching from the mounting plate 100 after multiple rotations.

[0044] In some embodiments, the two mounting portions are disposed at the diagonal of the mounting plate 100.

[0045] Specifically, by respectively arranging the two mounting portions at the diagonals on the front and back sides, the corresponding soldering mark station and glue discharging station can be staggered, so that the overall layout effect is better.

[0046] In some embodiments, the driver 300 is set as a motor, and the driving direction of the motor is set to alternate between clockwise and counterclockwise.

[0047] Specifically, the manner in which the motor drives the mounting plate 100 to rotate is known to those skilled in the art and can be implemented, and will not be described in detail in this embodiment. To prevent the cable of the taping mechanism 200 from being twisted due to continuous rotation in the same direction, the rotation direction of the motor alternates between clockwise and counterclockwise.

[0048] In some embodiments, the rotary taping device 10 further includes an angle sensor for detecting the rotation angle of the mounting portion, and the angle sensor is electrically connected to the driver 300.

[0049] Specifically, the angle sensor is set as a photoelectric sensor. The angle sensor is installed below the mounting plate 100, and the rotation angle of the mounting plate 100 can be detected by the photoelectric sensor and fed back to the motor.

[0050] Embodiment 3

[0051] Provided is a battery production device, including the rotary taping device of Embodiment 1 or 2, further including: a glue dispensing mechanism 400 for cutting the adhesive tape to the required length at the glue dispensing station and a soldering mechanism for soldering the adhesive tape onto the battery cell at the soldering mark station.

[0052] Specifically, the glue dispensing mechanism 400 is disposed below one of the taping mechanisms 200, and the soldering mechanism is disposed below the other taping mechanism 200.

[0053] In some embodiments, the glue dispensing mechanism 400 includes a large plate 410, a clamping assembly 420, a glue transfer assembly 430, and a glue cutting assembly 440. The glue transfer assembly 430, the clamping assembly 420, and the glue cutting assembly 440 are sequentially disposed on the large plate 410, and the glue cutting assembly 440 and the clamping assembly 420 are set at the glue dispensing station.

[0054] Specifically, the glue transfer assembly 430 includes a glue supply bracket and a reel installed on the glue supply bracket to carry the adhesive tape roll. The adhesive tape is released from the adhesive tape roll on the reel, and the clamping assembly 420 clamps the end of the released adhesive tape. The clamping assembly 420 can be, but is not limited to, clamping plates. The glue cutting assembly 440 cuts the adhesive tape with two cutting knives. The glue dispensing mechanism 400 further includes a support plate for supporting the cut sheet-shaped adhesive tape.

[0055] Its working principle is as follows: The alternation of two tape - sticking mechanisms 200 is realized by a motor. The first tape - sticking mechanism 200 and the second tape - sticking mechanism 200 are exactly the same, and their rotation angles can be detected by a photoelectric sensor under the mounting plate 100 of the tape - sticking mechanism 200 and fed back to the motor. Each tape - sticking mechanism 200 can change the distance between tapes through a variable - pitch cylinder 212, so as to realize the transformation of the tape distance from the glue - discharging mechanism 400 to the battery welding mark. When the glue - discharging mechanism 400 pulls out the tape and the scalpel cuts the tape, the lifting cylinder 2212 on the first tape - sticking mechanism 200 descends to drive the suction cup 2223 to suck the tape; after the lifting cylinder 2212 on the first tape - sticking mechanism 200 rises, the motor drives the mounting plate 100 of the tape - sticking mechanism 200 to rotate 180°. At the same time, the variable - pitch cylinder 212 on the first tape - sticking mechanism 200 opens to the width required for the cell welding mark, and the variable - pitch cylinder 212 on the second tape - sticking mechanism 200 retracts to the tape width when the glue - discharging mechanism 400 discharges glue; the first tape - sticking mechanism 200 rotates to the tape - sticking station of the cell welding mark, and the second tape - sticking mechanism 200 rotates above the glue - discharging mechanism 400 to perform the glue - cutting and glue - preparing actions; after the first tape - sticking mechanism 200 rotates to the tape - sticking station of the cell welding mark, the lifting cylinder 2212 on it descends to paste the tape at the battery welding mark position, the suction cup 2223 releases the vacuum, and then the lifting cylinder 2212 of the first tape - sticking mechanism 200 rises, the motor rotates, and the second tape - sticking mechanism 200 that has prepared the glue comes directly above the cell to prepare for the tape - sticking action; this is a cyclic action. The glue - sucking and tape - sticking processes of the second tape - sticking mechanism 200 are the same as those of the first tape - sticking mechanism 200.

Moreover, the first feature being above, over, and on top of the second feature includes the first feature being directly above and diagonally above the second feature, or merely indicating that the first feature has a higher horizontal height than the second feature. The first feature being below, under, and beneath the second feature includes the first feature being directly below and diagonally below the second feature, or merely indicating that the first feature has a lower horizontal height than the second feature.
