DETAILED DESCRIPTION

[0033] The technical solution of the utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all of the embodiments. The utility model will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0034] It should be noted that the terms "first", "second", etc. in the specification and claims of the utility model and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0035] In the present invention, unless otherwise specified, the directional words used, such as "up, down, top, bottom", usually refer to the directions shown in the drawings, or to the components themselves in the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directional words are not used to limit the present invention.

[0036] The utility model provides a pole piece conveying device 100, please refer to Figure 1 and Figure 2 The pole piece conveying device 100 includes a frame, and a conveying component 1 and a conveying drive component 2 arranged on the frame; the conveying component 1 includes a conveying roller 11 rotatably arranged on the frame; the conveying drive component 2 includes a first magnetic wheel 21 and a second magnetic wheel 22 arranged in coordination with each other, and a first driver 26 connected to the first magnetic wheel 21, the first driver 26 is used to drive the first magnetic wheel 21 to rotate, and the second magnetic wheel 22 is connected to the conveying roller 11; wherein, the first driver 26 drives the first magnetic wheel 21 to rotate, drives the second magnetic wheel 22 to rotate, and drives the conveying roller 11 to rotate together.

[0037] The utility model drives the first magnetic wheel 21 to rotate through the first driver 26. Under the magnetic force between the first magnetic wheel 21 and the second magnetic wheel 22, the second magnetic wheel 22 is driven to rotate, thereby driving the conveying roller 11 to rotate together to realize the transmission of the pole piece. Through the cooperation of the first magnetic wheel 21 and the second magnetic wheel 22, the drive of the conveying roller 11 utilizes adjacent opposite magnetic poles to promote rotation, realizes non-contact transmission of power, has higher driving efficiency, lower working noise, and no wear, can better ensure the smooth operation of the conveying roller 11, improve the yield of the pole piece, and ensure the quality of the pole piece.

[0038] The frame can be used to support both ends of the conveying roller 11, so as to be directly or indirectly connected to the conveying roller 11. The specific form of the frame is not specifically limited. Preferably, the frame can be a part of the box of the coating machine oven, so that the electrode conveying device 100 is covered in the box, thereby better protecting the electrode conveying device 100 from damage.

[0039] It should be noted that the magnetic wheel is also called a magnetic gear or a magnetic gear. The magnetic wheel generally includes an active magnetic wheel and a driven magnetic wheel. The active magnetic wheel and the driven magnetic wheel use repulsive force to convert into driving force. Among them, in the static state, the N and S poles of the two magnetic wheels correspond to each other. When the active magnetic wheel rotates, the position of the magnetic pole changes, and the adjacent opposite magnetic poles are used to push the driven magnetic wheel to rotate, thereby realizing non-contact magnetic transmission of power. In the utility model, the first magnetic wheel 21 is an active magnetic wheel, the second magnetic wheel 22 is a driven magnetic wheel, and the first driver 26 can be set as a driving motor. The first driver 26 drives the first magnetic wheel 21 to rotate, so that under the magnetic force of the first magnetic wheel 21 and the second magnetic wheel 22, the second magnetic wheel 22 is driven to rotate together to realize the rotation of the conveying roller 11. The driving of the conveying roller 11 is realized by non-contact magnetic force, so that the conveying roller 11 is more stable and less prone to fluctuations when rotating, and the pole piece is not easily deformed when being conveyed by the conveying roller 11, thereby better ensuring that the pole piece is not damaged.

[0040] Specifically, the rotation axis of the first magnetic wheel 21 is perpendicular to the rotation axis of the second magnetic wheel 22, so that a orthogonal transmission or a right-angle cone transmission can be formed between the first magnetic wheel 21 and the second magnetic wheel 22, so that the structure of the transmission drive assembly 2 is more compact, thereby occupying less space.

[0041] In another embodiment, the rotation axis of the first magnetic wheel 21 and the rotation axis of the second magnetic wheel 22 may be parallel to each other, so that the structure is simpler.

[0042] Among them, combined Figure 1 and Figure 2As shown, the conveying assembly 1 includes a mounting plate 23 and an adjusting assembly 24 connected to the mounting plate 23, the conveying roller 11 and the adjusting assembly 24 are respectively arranged on both sides of the mounting plate 23, and the rotating shaft of the conveying roller 11 passes through the mounting plate 23 and is rotatably connected to the adjusting assembly 24, and the adjusting assembly 24 is used to adjust the conveying roller 11 to move in the up-down direction of the frame. Preferably, the first magnetic wheel 21 and the second magnetic wheel 22 are orthogonal transmission, the axial direction of the conveying roller 11 is arranged along the lateral extension of the frame, the driving shaft of the first driver 26 is arranged along the up-down direction of the frame, the first magnetic wheel 21 is arranged on the driving shaft of the first driver 26, the second magnetic wheel 22 is arranged on the portion of the conveying roller 11 extending from the mounting plate 23, and the first magnetic wheel 21 and the second magnetic wheel 22 are arranged correspondingly. Placing the first magnetic wheel 21, the second magnetic wheel 22, the first driver 26 and the conveying roller 11 on both sides of the mounting plate 23 respectively can avoid interference between the magnetic wheels and the first driver 26 and the conveying roller 11, while also ensuring that the first magnetic wheel 21, the second magnetic wheel 22 and the first driver 26 have more installation space, thereby facilitating maintenance.

[0043] It should be noted again that when the pole piece conveying device 100 is working normally, the conveying roller 11 is extended in the horizontal direction, and the driving shaft of the first driver 26 is arranged in the up-down direction. For the convenience of description, in the present invention, the axial direction of the conveying roller 11 is along the front-back direction of the frame. Unless otherwise specified, the description of the relevant directions in the present invention can be referred to in this way.

[0044] Furthermore, if Figure 2 and Figure 3As shown, the adjustment assembly 24 includes an adjustment plate 241, an adjustment member 243 and a locking member. The adjustment plate 241 is arranged on the side of the mounting plate 23 facing away from the conveying roller 11. The conveying roller 11 is rotatably connected with the adjustment plate 241. A locking portion 242 is arranged on the adjustment plate 241. The adjustment member 243 is movably arranged on the mounting plate 23. The adjustment member 243 has a locking state in which it abuts against the mounting plate 23 along the radial direction of the conveying roller 11, and has an unlocking state separated from the mounting plate 23. The locking member is locked and matched with the locking portion 242 to lock the adjustment plate 241 along the axial direction of the conveying roller 11. The adjustment member 243 can realize the locking and unlocking of the adjustment plate 241 along the radial direction of the conveying roller 11, and the locking member can realize the locking and unlocking of the adjustment plate 241 along the axial direction of the conveying roller 11, so that the adjustment member 243 is easy to disassemble and move.

[0045] Preferably, the locking portion 242 includes an adjustment slot 2421 provided on the adjustment plate 241, and the adjustment slot 2421 is arranged in an arc shape that is bent in the up-down direction of the frame.

Since the adjustment slot 2421 is arranged in an arc shape, and the curvature of the adjustment slot 2421 is consistent with the curvature of the arc with the screw at the first end as the rotation center, when the height of the conveying roller 11 is to be slightly adjusted, the locking member can be unlocked so that the adjustment plate 241 can be rotated along the screw at the first end. When it is rotated to a suitable position, the locking member is locked at the adjustment slot 2421, so that the adjustment of the conveying roller 11 is more convenient, so as to ensure that the multiple conveying rollers 11 in the coating machine oven can better maintain a consistent height and be more stable when conveying the electrode.

[0046] Furthermore, a first matching hole is provided on the mounting plate 23, and the locking member includes a locking pin 25, which is passed through the adjustment groove 2421 and is threadedly connected to the first matching hole, so that the locking pin 25 can be easily unlocked and locked, thereby making fine adjustment of the conveying roller 11 more convenient.

[0047] Preferably, the adjusting member 243 includes two adjusting blocks 2431 and two adjusting pins 2432. The two adjusting blocks 2431 are respectively arranged on opposite sides of the adjusting plate 241. Specifically, the two adjusting blocks 2431 are respectively located on both sides of the adjusting plate 241 along the left-right direction; the two adjusting pins 2432 are screwed on the two adjusting blocks 2431 one by one, and can pass through the corresponding adjusting blocks 2431 to abut against the two sides of the adjusting plate 241, and each adjusting pin 2432 can be screwed in and out relative to the corresponding adjusting block 2431. By adjusting the adjusting pin 2432 to screw in the adjusting block 2431, the adjusting pin 2432 can move toward the direction close to the adjusting plate 241 to achieve locking of the adjusting plate 241; by adjusting the adjusting pin 2432 to screw out of the adjusting block 2431, the adjusting pin 2432 can move toward the direction away from the adjusting plate 241 to achieve unlocking of the adjusting plate 241. The two adjusting pins 2432 make it more reliable to fix the adjusting plate 241 on the mounting plate 23 , so as to ensure the working stability of the conveying roller 11 .

[0048] Moreover, the side surface of the adjustment plate 241 abutting against the adjustment pins 2432 is arranged in an arc shape, so that after the adjustment plate 241 is fine-tuned and rotated, it is ensured that each adjustment pin 2432 can still better abut against the side surface of the adjustment plate 241, thereby achieving a better locking effect on the adjustment plate 241.
