[0108] In some embodiments of the present application, Figures 1 to 5As shown, a gripping device 30 is proposed, which includes a base 31, a drive shaft 32, a drive mechanism 34 and at least one gripping mechanism 33. The drive shaft 32 is rotatably mounted on the base 31, at least one gripping mechanism 33 is mounted on the drive shaft 32 and rotates synchronously with the drive shaft 32, the drive mechanism 34 is mounted on the base 31, the drive mechanism 34 includes a drive assembly 341 and a crank transmission assembly 342, the drive assembly 341 includes a drive seat 3411 that can reciprocate along a first direction a, the drive seat 3411 is transmission-connected to the drive shaft 32 through the crank transmission assembly 342 to drive the drive shaft 32 to rotate, and the first direction a is perpendicular to the rotation axis direction b of the drive shaft 32.

[0109] In the present application, the grabbing mechanism 33 is a mechanism capable of performing grabbing and gluing operations. When gluing the battery cell, the grabbing mechanism 33 grabs the film and sticks the film to the gluing surface of the battery cell.

[0110] Furthermore, the crank-connecting rod assembly forms a crank mechanism, wherein the crank mechanism is capable of converting a linear motion into a rotational motion.

[0111] When the grabbing device 30 performs the gluing operation on the battery cell, the grabbing mechanism 33 grabs the film, and the driving seat 3411 of the driving component 341 moves in the first direction a, thereby driving the driving shaft 32 through the crank transmission component 342 to rotate the driving shaft 32. Driven by the driving shaft 32, the grabbing mechanism 33 rotates synchronously with the driving shaft 32 and adjusts the direction so that the film corresponds to the gluing surface of the battery cell, thereby realizing the gluing operation on the battery cell.

[0112] In some embodiments of the present application, Figure 3 and Figure 4 As shown, the crank transmission assembly 342 includes a first transmission member 3421 and a second transmission member 3422. The first transmission member 3421 is fixedly mounted on the driving seat 3411, and the second transmission member 3422 is fixedly mounted on the driving shaft 32. The second transmission member 3422 is rotatably connected to the first transmission member 3421.

[0113] Specifically, the first transmission member 3421 is fixedly installed on the driving seat 3411, and the second transmission member 3422 is fixedly installed on the driving shaft 32. In the radial direction of the driving shaft 32, the second transmission member 3422 protrudes out of the radial direction of the driving shaft 32. The first transmission member 3421 is connected to the second rotating member, and the two can rotate relative to each other.

[0114] When the driving seat 3411 moves along the first direction a, the driving seat 3411 drives the first transmission member 3421 to move synchronously. During the movement, the first transmission rod drives the second transmission member 3422 to rotate relative to the first transmission rod. The rotation of the second transmission rod drives the driving shaft 32 to rotate synchronously, thereby realizing the conversion of the linear motion of the driving seat 3411 into the rotation of the driving shaft 32.

[0115] It should be understood that, during the movement of the crank transmission assembly 342, the first transmission member 3421 moves in a first plane, and the second transmission member 3422 rotates in a second plane, wherein the first plane and the second plane are parallel to each other.

[0116] The first transmission member 3421 and the second transmission member 3422 form a crank transmission assembly 342 with a simple structure, thereby transmitting the linear motion of the driving seat 3411 to the driving shaft 32 and causing the driving shaft 32 to rotate, thereby simplifying the mechanism and reducing the manufacturing cost of the grasping device 30.

[0117] In some embodiments of the present application, Figure 3 and Figure 4 As shown, a waist-shaped hole 34211 is provided on the first transmission member 3421, and the crank transmission assembly 342 also includes a connecting shaft 3423, which is fixedly mounted on the second transmission member 3422. The connecting shaft 3423 passes through the waist-shaped hole 34211 and can slide relative to the waist-shaped hole 34211 along the length direction of the waist-shaped hole 34211.

[0118] Specifically, in the present application, the first transmission member 3421 includes a first arm and a second arm, one end of the first arm is vertically connected to one end of the second arm, the first arm is connected and fixed to the driving seat 3411, the waist-shaped hole 34211 is opened on the second arm, and the length direction of the waist-shaped hole 34211 is perpendicular to the first direction a, the connecting shaft 3423 is passed through the waist-shaped hole 34211 and is fixedly connected to the second transmission member 3422, and in the length direction of the waist-shaped hole 34211, the connecting shaft 3423 can slide relative to the waist-shaped hole 34211, and the connecting shaft 3423 can also rotate relative to the waist-shaped hole 34211.

[0119] When the driving seat 3411 moves along the first direction a, the driving seat 3411 drives the first transmission member 3421 to move synchronously. During the movement, the first transmission rod drives the connecting shaft 3423, so that the connecting shaft 3423 moves along the length direction of the waist-shaped hole 34211. During the movement, the connecting shaft 3423 rotates relative to the waist-shaped hole 34211, and the connecting shaft 3423 drives the second transmission rod to rotate. The second transmission rod drives the driving shaft 32 to rotate synchronously, thereby realizing the conversion of the linear motion of the driving seat 3411 into the rotation of the driving shaft 32.

[0120] The connecting shaft 3423 and the waist-shaped hole 34211 are provided so that the connection position between the first transmission member 3421 and the second transmission member 3422 can effectively realize transmission, so as to convert the linear motion of the driving seat 3411 into the rotation of the driving shaft 32, thereby realizing the adjustment of the direction of the grasping mechanism 33.

[0121] It should be noted that the connection and fixing methods between the connecting shaft 3423 and the second transmission member 3422 include but are not limited to welding, bonding, clamping or connection via fasteners.

[0122] In the present application, the connecting shaft 3423 and the second transmission member 3422 are connected via bolts. The bolt connection can realize the detachable connection between the connecting shaft 3423 and the second transmission member 3422. The detachable connection can realize the separate maintenance and replacement of the connecting shaft 3423 and the second transmission member 3422, thereby reducing the cost of maintenance and replacement.

The driving seat 3411 can abut against the first buffer 3413 or the second buffer 3414 to limit the moving stroke of the driving seat 3411.

[0144] Specifically, the first buffer 3413 and the second buffer 3414 are respectively mounted on the cylinder of the telescopic member 3412, and the first buffer 3413 and the second buffer 3414 are spaced apart in the first direction a, and the area between the first buffer 3413 and the second buffer 3414 is the moving area of ​​the driving seat 3411. When the driving seat 3411 abuts against the first buffer 3413, the driving member reaches the maximum stroke position on one side of the first direction a, and when the driving seat 3411 abuts against the second buffer 3414, the driving member reaches the maximum stroke position on the other side of the first direction a.

When the driving seat 3411 moves to one side of the second buffer 3414, the driving seat 3411 abuts against the second buffer 3414 through the stopper 3415.

[0148] In addition, the first buffer member 3413 may be a hydraulic buffer or a spring, etc. Similarly, the second buffer member 3414 may also be a hydraulic buffer or a spring, etc.

[0149] In some embodiments of the present application, the first buffer member 3413 is a first oil pressure buffer.

[0150] Specifically, by disposing the first buffer member 3413 , the structure of the first buffer member 3413 can be simplified, thereby reducing the volume of the first buffer member 3413 , thereby reducing the impact on the overall volume of the grasping device 30 .

The second stopper 352 is also fixedly mounted on the base 31 and is located radially outside the drive shaft 32. Along the circumferential direction of the drive shaft 32, the first stopper 351 and the second stopper 352 are arranged at intervals. The connection and fixing methods between the second stopper 352 and the base 31 include, but are not limited to, welding, bonding, clamping, or connection via fasteners.

The stopper 353 and the drive shaft 32 are detachably connected, so that the components can be replaced individually, thereby effectively reducing the cost of maintenance and replacement.

[0155] When the driving shaft 32 rotates, the limit member 353 rotates synchronously with the driving shaft 32. When the limit member 353 abuts against the first stop member 351, the driving shaft 32 reaches the maximum position on one side of its rotation direction. When the limit member 353 abuts against the second stop member 352, the driving shaft 32 reaches the maximum position on the other side of its rotation direction.

[0156] By utilizing the cooperation between the limit member 353 and the first stop member 351 and the second stop member 352, the rotation stroke of the drive shaft 32 can be limited, and the adjustment range of the direction of the grasping mechanism 33 can be controlled, so that the grasping device 30 can effectively adapt to the needs of battery production.

[0157] It should be understood that the angle between the first stopper 351 and the second stopper 352 along the circumferential direction of the drive shaft 32 can be 30°, 45°, 60°, 75°, 90°, 105°, 120°, 135°, or 150°.

[0159] Specifically, the third buffer 354 is mounted on the first stopper 351, the fourth buffer 355 is mounted on the second stopper 352, and the area between the third buffer 354 and the fourth buffer 355 is the rotation area of ​​the limiter 353. When the limiter 353 abuts against the third buffer 354, the driving member reaches the maximum stroke position on one side of the rotation direction of the driving shaft 32, and when the driving seat 3411 abuts against the fourth buffer 355, the driving member reaches the maximum stroke position on the other side of the rotation direction of the driving shaft 32.

[0160] At the same time, the third buffer member 354 and the fourth buffer member 355 both have buffering properties. When the driving seat 3411 abuts against the third buffer member 354 or the fourth buffer member 355, the third buffer member 354 or the fourth buffer member 355 absorbs the impact force of the driving seat 3411, and the third buffer member 354 and the fourth buffer member 355 are used to limit the limit member 353, thereby reducing the collision of the limit member 353 and reducing vibration and noise.
