[0037] In the description of the embodiments of the present application, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a replaceable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium; it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific circumstances.

[0038] Please refer to Figures 1 to 3 , in the first aspect of the embodiments of the present application, a contactless transmission and conveying mechanism is provided, including: a motor 10, a transmission wheel set, and a roller 30.

[0039] The transmission wheel set includes: a driving wheel 21 and a driven wheel 22. The motor 10 is drivingly connected to the driving wheel 21 for driving the driving wheel 21 to rotate. In this solution, the motor 10 can be a reduction motor, and its output end can drive the driving wheel 21 to rotate by means of a fixed connection with the driving wheel 21, so as to reduce the wear between the driving wheel 21 during the transmission process and the driving wheel 21, and avoid the generation of debris due to the wear of the driving wheel 21.

[0040] The driven wheel 22 is arranged beside the driving wheel 21 and is magnetically coupled with the driving wheel 21, so that when the driving wheel 21 rotates, it can drive the driven wheel 22 to rotate through magnetic force; the driven wheel 22 is fixedly connected to the roller 30 for driving the roller 30 to rotate.

[0041] That is to say, in this embodiment, when the driving wheel 21 rotates, it can drive the driven wheel 22 to rotate without contacting the driven wheel 22 through the change of magnetic poles, and contactless transmission can be achieved. It should be noted that the principle of the driving wheel 21 driving the driven wheel 21 to rotate through magnetic force is a prior art and will not be elaborated in this embodiment.

[0042] During the transmission process, the motor 10 driving the driving wheel 21 to rotate can avoid the gear meshing method and does not generate debris; the same is true for the transmission method between the driven wheel 22 and the roller 30. The two can adopt a direct fixed connection method to achieve synchronous rotation, which can also reduce the debris generated during the transmission process, reduce the impact on the pole piece conveyed on the roller 30, and ensure the quality of the battery produced subsequently. Moreover, the contactless magnetic force transmission method can avoid the uncertain factors brought by too loose or too tight cooperation during gear contact transmission, and at the same time can effectively reduce the noise during the transmission process and reduce the loss of transmission components.

[0043] As an implementation manner, in the transmission wheel set, the axial direction of the driving wheel 21 and the axial direction of the driven wheel 22 are perpendicular to each other, which can effectively improve the transmission efficiency between the driving wheel 21 and the driven wheel 22.

[0044] In one embodiment, both the drive pulley set and the idler roller 30 include a plurality; the plurality of drive pulley sets and the plurality of idler rollers 30 are connected in one-to-one correspondence; the motor 10 is drivingly connected to the driving wheels 21 in the plurality of drive pulley sets.

[0045] Specifically, a connecting rod 40 may be fixedly connected to the output end of the motor 10; the driving wheels 21 of the plurality of drive pulley sets are fixedly sleeved on the connecting rod 40, so that the motor 10 can drive the plurality of driving wheels 21 to rotate synchronously by driving the connecting rod 40 to rotate, realizing the conveyance of the pole piece on the plurality of idler rollers 30.

[0046] As an implementation manner, the output end of the motor 10 is drivingly connected to the middle of the connecting rod 40; the plurality of drive pulley sets are symmetrically arranged with respect to the connecting rod 40, so that the motor 10 can evenly output the driving force to both ends of the connecting rod 40, avoiding the high-power output of the driving force of the motor 10 at one end, which can improve the service life of the motor 10 and the connecting rod 40, and at the same time improve the stability of the conveyance of the idler roller 30.

[0047] In a more specific embodiment, a bracket 50 is further included; the idler roller 30 is rotatably arranged on the bracket 50 through a first bearing 31; the drive pulley set is arranged on the bracket 50.

[0048] Furthermore, the idler roller 30 includes an inner shaft core 33 and an outer roller sleeve 34; the inner shaft core 33 is rotatably arranged on the bracket 50 through a first bearing 31; the outer roller sleeve 34 is rotatably sleeved on the inner shaft core 33 through a second bearing 32.

[0049] That is to say, in this embodiment, the inner shaft core 33 can rotate on the bracket 50 through the first bearing 31; the outer roller sleeve 34 can rotate on the inner shaft core 33 through the second bearing 32. Therefore, the outer roller sleeve 34 has a degree of freedom to rotate freely relative to the inner shaft core 33, so that the roller surface of the idler roller 30 can indirectly reach a semi-free turntable, enabling the rotation speed of the idler roller 30 to match the speed of the pole piece and improving the stability of conveying the pole piece.

[0050] It should be noted that there is a pulling force on the pole piece conveyed on the idler roller 30, that is, in the case where the idler roller 30 does not rotate, the pole piece can also move on the idler roller 30. Therefore, setting the first bearing 31 and the second bearing 32 in this embodiment will not cause idling between the idler roller 30 and the pole piece and result in the situation where the pole piece cannot be conveyed.

[0051] As an implementation manner, a vacuum suction nozzle is arranged on the idler roller 30, so that the idler roller 30 can suck and hold the pole piece located on the idler roller 30, improving the stability of the pole piece during the conveyance process and enabling the pole piece to be conveyed below the idler roller 30 as well.

[0052] As another implementation, it further includes a hair dryer 60; the hair dryer 60 is disposed below the over-roller 30 so that the electrode sheet located below the over-roller 30 is attached to the over-roller 30 under the blowing force of the hair dryer 60.

[0053] Specifically, both the top surface and the bottom surface of the over-roller 30 can be used to convey the electrode sheet; and through the hair dryer 60, the electrode sheet located on the bottom surface of the over-roller 30 can be lifted by the blowing force and attached to the bottom surface of the over-roller 30, avoiding the sagging or falling off of the electrode sheet.

[0054] The second aspect of the present application provides a coating machine, including the non-contact transmission and conveying mechanism of any one of the above.

[0055] The above are the preferred embodiments of the present application and are not used to limit the present invention. Although the present application has been described in detail with reference to the examples, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing examples, or perform equivalent replacements on some of the technical features. However, any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
