However, the state of the rubber pressure roller under manual adjustment cannot be quantified. Sometimes it is easy to be loose on one side and tight on the other side, and sometimes it is easy to over-adjust, resulting in wrinkling of the electrode tabs, which has a certain impact on the product manufacturing process of the subsequent process.

Therefore, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0044] Embodiment 1:

[0045] This embodiment provides a rubber pressing roller mechanism, including:

[0046] A bracket;

[0047] A rubber pressing roller 1, with swing arms 2 provided at both ends of the rubber pressing roller 1, and the swing arms 2 are rotatably connected to the bracket;

[0048] A control component, the swing arm 2 includes a driving end, and the control component is connected to the driving end of the swing arm 2 for controlling the swing arm 2 to rotate to drive the rubber pressing roller 1 to approach or move away from the traction roller 3;

[0049] An adjusting component, the adjusting component includes an inclined push block 4 and a driving module for driving the inclined push block 4 to reciprocate, the inclined surface of the inclined push block 4 abuts against the driving end of the swing arm 2, and the movement of the inclined push block 4 drives the driving end to approach or move away from the control component;

[0050] A pressure sensing component 5, which is installed on the driving end of the swing arm 2 and is used to detect the pressure between the rubber pressing roller 1 and the pole piece.

[0051] In this technical solution, a rotatable traction roller 3 and a rubber pressing roller 1 are installed on the bracket, and the pole piece to be coated passes between the traction roller 3 and the rubber pressing roller 1. Before coating, the control component is used to control the swing arm 2 to move to drive the rubber pressing roller 1 to approach the traction roller 3. When the distance between the rubber pressing roller 1 and the traction roller 3 reaches a reasonable range, the driving end of the swing arm 2 abuts against the inclined push block 4, so as to ensure that the pressure of the rubber pressing roller 1 can be set within a reasonable range. The gap between the rubber pressing roller 1 and the traction roller 3 is a gap suitable for the pole piece to pass through, and the pole ear of the pole piece will not be wrinkled.

[0052] When the rubber pressing roller 1 is worn after long-term operation, the gap between the rubber pressing roller 1 and the traction roller 3 will become larger. The pressure sensing component 5 senses the pressure change between the rubber pressing roller 1 and the pole piece, and the driving module of the adjusting component controls the inclined push block 4 to drive the swing arm 2 to move, so that the rubber pressing roller 1 approaches the traction roller 3 to make the pole piece to be coated be pressed tightly.

[0053] To sum up, it can realize the automatic adjustment of the rubber pressing roller 1 during the coating operation, thus avoiding the work abnormality caused by the staff's inability to accurately adjust the pressing degree of the rubber pressing roller 1, and further ensuring the coating quality of the pole piece and effectively improving the compatibility during the coating process.

[0054] Embodiment 2:

[0055] This embodiment provides a rubber pressing roller mechanism, which has the following technical features in addition to including the technical solution of the above embodiment.

[0056] Further, the control component includes:

[0057] A fixed seat 6;

[0058] The first driving member 7 is installed on the fixed seat 6.

[0059] The connecting member 8 is installed on the driving end of the first driving member 7 and is rotatably connected to the driving end of the swing arm 2.

[0060] In this technical solution, the fixed seat 6 is installed on the bracket, the first driving member 7 is installed on the fixed seat 6, and the driving end of the first driving member 7 is movably connected to the driving end of the swing arm 2 through the connecting member 8. When the inclined push block 4 moves and causes the driving end of the swing arm 2 to move, the entire swing arm 2 will rotate around the connection between the connecting member 8 and the swing arm 2, thereby driving the rubber pressing roller 1 to approach or move away from the traction roller 3, and further playing a role in adjusting the pressing degree between the rubber pressing roller 1 and the pole piece.

[0061] Further, the first driving member 7 is a cylinder. The connecting member 8 is installed on the output end of the cylinder. The rotation of the swing arm 2 will drive the connecting member 8 to move, affecting the telescopic amount of the cylinder, thereby realizing the change in the distance between the rubber pressing roller 1 and the traction roller 3.

[0062] Embodiment 3:

[0063] This embodiment provides a rubber pressing roller mechanism, which, in addition to including the technical solution of the above embodiment, further has the following technical features.

[0064] Further, the driving module includes:

[0065] The mounting seat 9, on which the inclined push block 4 is reciprocally movably installed;

[0066] The second driving member is installed on the mounting seat 9 and is used to drive the inclined push block 4 to reciprocate.

[0067] In this technical solution, the second driving member is used to control the reciprocating movement of the inclined push block 4 on the mounting seat 9 to realize the rotation of the swing arm 2 around the connection between the connecting member 8 and the swing arm 2, thereby affecting the telescopic amount of the cylinder and realizing the adjustment of the distance between the rubber pressing roller 1 and the traction roller 3.

[0068] Embodiment 4:

[0069] This embodiment provides a rubber pressing roller mechanism, which, in addition to including the technical solution of the above embodiment, further has the following technical features.

[0070] Further, the second driving member includes:

[0071] The motor 10 is installed on the mounting seat 9;

[0073] Among them, the inclined push block 4 is threadedly connected to the lead screw 11.

[0074] In this technical solution, the second driving member is composed of a motor 10 and a lead screw 11. A guide rail or a guide rod is provided on the mounting seat 9. The inclined push block 4 is installed on the guide rail or the guide rod. The guide rail or the guide rod plays a role in limiting and guiding the reciprocating movement of the inclined push block 4. By driving the lead screw 11 to rotate through the motor 10, the inclined push block 4 is driven to move along the axial direction of the lead screw 11. Through this structural design, the movement stability of the inclined push block 4 can be enhanced.

[0075] It is worth mentioning that the output end of the motor 10 and the lead screw 11 are connected by a flexible coupling or a flexible coupler, which can absorb the vibration and impact generated at the connection between the motor 10 and the lead screw 11 during the operation of the motor 10, and reduce the influence on the battery and the lead screw 11. In addition, the flexible coupling can compensate for the axial and radial deviations to a certain extent, and can effectively improve the transmission stability.

[0076] Embodiment 5:

[0077] This embodiment provides a rubber pressing roller mechanism, which has the following technical features in addition to the technical solution of the above embodiment.

[0078] Furthermore, the pressure sensing assembly 5 includes:

[0079] A fixed block 501, the fixed block 501 is in contact with the inclined push block 4;

[0081] A fixing plate 503, the fixing plate 503 is installed on the pressure sensor 502 and is connected to the driving end of the swing arm 2.

[0082] Furthermore, the bottom end of the fixed block 501 is provided with an inclined surface structure adapted to the inclined push block 4.

[0083] In this technical solution, as Figure 3 shown, the inclined surface of the fixed block 501 is in contact with the inclined surface of the inclined push block 4. The fixed block 501 can be prevented from moving in the X direction by setting a guide rod or a guide rail structure (not shown in the figure). When the motor 10 controls the lead screw 11 to rotate and drives the inclined push block 4 to move rightward in the X direction, the fixed block 501 will move upward, driving the telescopic amount of the air cylinder to become smaller, so that the gap between the rubber pressing roller 1 and the traction roller 3 becomes larger; conversely, when the lead screw 11 rotates reversely, the inclined push block 4 moves leftward in the X direction, the fixed block 501 moves downward, driving the telescopic amount of the air cylinder to become larger, and the gap between the rubber pressing roller 1 and the traction roller 3 becomes smaller.

[0084] Embodiment 6:

[0085] This embodiment provides a rubber pressure roller mechanism, which, in addition to including the technical solutions of the above embodiments, further has the following technical features.

[0086] Furthermore, the fixed block 501, the pressure sensor 502 and the fixed plate 503 are connected by setting fasteners.

[0087] In this technical solution, the fixed block 501, the pressure sensor 502 and the fixed plate 503 are connected and fixed together by setting fasteners, enhancing the structural stability of the pressure sensing assembly 5 and making the overall movement of the pressure sensing assembly 5 smoother.

[0088] Furthermore, the fastener is a screw;

[0089] The fixed plate 503 is provided with a first mounting hole;

[0090] The pressure sensor 502 is provided with a second mounting hole;

[0091] The fixed block 501 is provided with a third mounting hole;

[0092] Among them, the first mounting hole, the second mounting hole and the third mounting hole are sequentially communicated. The head of the screw abuts against the fixed plate 503. The threaded part of the screw penetrates through the first mounting hole and the second mounting hole and is threadedly connected to the third mounting hole.

[0093] In this technical solution, the first mounting hole is a counterbore structure and penetrates through the fixed plate 503. The second mounting hole penetrates through the pressure sensor 502 and is correspondingly communicated with the first mounting hole. The third mounting hole is a threaded hole and is correspondingly communicated with the second mounting hole. By setting the screw to pass through the first mounting hole and the second mounting hole and be threadedly connected to the third mounting hole, the fixed plate 503, the pressure sensor 502 and the fixed block 501 can be connected and locked, enhancing the connection stability. In addition, the head of the screw is located in the counterbore of the first mounting hole and does not protrude, hiding the head of the screw, reducing the influence of the external environment on the force of the screw head, reducing the risk of damage or loosening of the threaded head due to external force, and also improving the flatness and aesthetic degree of the fixed plate 503 to a certain extent.
