[0003] The fixture is a conical groove. After the battery cell is inserted into the conical groove, both ends of the battery cell protrude outside the fixture. The two ends of the battery cell protruding from the fixture are clamped by clamping tools and moved to the corresponding workstation. The battery cell is coated with rubber by a robotic arm that holds the rubber tape (B) and rotates around the battery cell. The coating action is complicated and the coating quality is unstable. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings and deficiencies of the prior art by providing a device for coating the tabs of a large cylindrical battery with all tabs for use in magnetic levitation transportation.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] The present invention discloses a coating device for a large cylindrical battery with multiple tabs for magnetic levitation transportation. It includes a main support, a frame connected to the main support, and a movable gripper slidably connected to the frame. The frame is fixed with an unwinding mechanism and a fixed gripper. A cutting assembly fixed to the frame is disposed between the fixed gripper and the movable gripper. Below the cutting assembly is a coating module capable of driving the battery cell to rotate around its axis. The coating module can drive the battery cell to perform lifting and lowering movements.

[0007] Furthermore, the overmolding module includes a cell rotation module capable of lifting the cell and causing the cell to rotate around its axis, and a cell drive assembly capable of driving the cell to rotate.

[0008] Furthermore, the cell rotation module includes two symmetrically arranged cell support modules; each cell support module includes a support, an ejection cylinder, a lifting cylinder, a lifting seat that can slide up and down on the support, and a sliding seat slidably connected to the lifting seat; one end of the ejection cylinder is fixed to the lifting seat; the other end of the ejection cylinder is fixed to the sliding seat; a turntable connecting seat is fixed to the sliding seat; a turntable is rotatably connected to the turntable connecting seat; a horizontal guide rail is fixed to the surface of the lifting seat; and a lifting power module that can drive the lifting seat to move up and down is fixed to the support.

[0009] Furthermore, the lifting power module is a lifting cylinder; one end of the lifting cylinder is fixed on the support; the other end of the lifting cylinder is fixed on the lifting seat; the lifting seat is rotatably connected to two rollers arranged in the horizontal direction.

[0010] Furthermore, the turntable is made of insulating material.

[0011] Furthermore, the battery cell drive assembly includes a rotating shaft rotatably connected to the support and a rotary power module capable of driving the rotating shaft to rotate; a friction wheel is fixed on the rotating shaft.

[0012] Furthermore, the rotary power module includes a drive pulley rotatably connected to the support and a driven pulley fixed to the rotating shaft; a belt is tensioned between the driven pulley and the drive pulley; and a servo motor capable of driving the drive pulley to rotate is fixed on the support.

When the tape is pulled out, the fixed clamp releases its grip on the tape, and the moving clamp holds and fixes the end of the tape. The linear module drives the moving clamp to perform linear motion, pulling the tape out a set length, waiting for the battery cell to enter directly above the coating module. After the battery cell is transported to directly above the coating module via the magnetic levitation transport rail, the coating module lifts the battery cell within the magnetic levitation transport rail fixture, allowing the battery cell to...

[0031] The invention will now be further described with reference to the accompanying drawings.

[0032] like Figure 1 and 2 As shown, the present invention discloses a coating device for a large cylindrical battery with multiple tabs for magnetic levitation transportation. It includes a main support 6, a frame 10 connected to the main support 6, and a movable gripper 7 slidably connected to the frame 10. The frame 10 is fixed with an unwinding mechanism 1 and a fixed gripper 4. A cutter assembly 3, fixed to the frame 10, is disposed between the fixed gripper 4 and the movable gripper 7. Below the cutter assembly 3 is a coating module 5 capable of driving the battery cell to rotate around its axis. The coating module 5 can drive the battery cell to perform lifting and lowering movements. The unwinding mechanism 1 is essentially no different from existing technologies and therefore will not be described in detail.

[0033] A linear module fixed on the frame 10 is connected to the movable gripper 7; the linear module can drive the movable gripper 7 to slide on the frame 10; the cutter assembly 3 consists of a cutter and a cylinder that drives the cutter to move.

[0034] The tape B unwound from the unwinding mechanism 1 passes through the counterweight, tension wheel, and guide wheel, and then passes through the two jaws of the fixed jaw 4. It is then clamped and fixed by the passive jaw 7. When the tape B is pulled out, the fixed jaw 4 releases its grip on the tape B. After the moving jaw 7 clamps and fixes the end of the tape B, the linear module drives the moving jaw 7 to make a linear motion. The linear module drives the moving jaw 7 to pull the tape B out to the set length, waiting for the battery cell to enter directly above the coating module 5.

[0035] After the battery cell is transported to the top of the coating module 5 via the magnetic levitation transport rail, the coating module 5 lifts the battery cell inside the magnetic levitation transport rail fixture, causing the battery cell to separate from the fixture; the battery cell continues to rise until it contacts the tape B and a portion of the tape B is pasted and fixed on the surface of the battery cell.

[0036] The fixed gripper 4 clamps and fixes the tape B, and the cutter assembly 3 cuts the tape B. The tape B automatically falls onto the surface of the battery cell and is stuck to the battery surface from the cut position to the end of the tape B that contacts the battery cell.

[0037] The coating module 5 drives the battery cell to rotate, and the tape B clamped in the moving jaw 7 is wound up and pasted onto the surface of the battery cell. When the coating is wound up, the linear speed of the tape B is equal to the moving speed of the moving jaw 7, which reduces the tension on the tape B and also prevents the tape B from being folded and stuck together.

[0038] After the coating is completed, the battery cell is lowered through the coating module 5 and then placed back onto the fixture; this structure enables automatic coating of the battery cell, the coating action is simple, and the coating quality is more stable.

[0039] like Figure 3 , 4 As shown in Figure 5, in a preferred embodiment of the present invention, the overmolded module 5 includes a cell rotation module capable of supporting the cell and causing the cell to rotate about the cell's axis, and a cell drive assembly capable of driving the cell to rotate.

[0040] The cell rotation module includes two symmetrically arranged cell support modules 5A. Each cell support module 5A includes a support 5A1, a push-out cylinder 5A6, a lifting cylinder 5A9, a lifting seat 5A2 that can slide up and down on the support 5A1, and a sliding seat 5A11 slidably connected to the lifting seat 5A2. One end of the push-out cylinder 5A6 is fixed to the lifting seat 5A2, and the other end is fixed to the sliding seat 5A11. A turntable connecting seat 5A5 is fixed to the sliding seat 5A11, and a turntable 5A4 is rotatably connected to the turntable connecting seat 5A5. A horizontal guide rail 5A10 is fixed to the surface of the lifting seat 5A2. A slider is provided inside the sliding seat 5A11. The sliding seat 5A11 achieves a sliding connection with the lifting seat 5A2 through the slider and the horizontal guide rail 5A10.

[0041] One end of the lifting cylinder 5A9 is fixed on the support 5A1; the other end of the lifting cylinder 5A9 is fixed on the lifting seat 5A2; the lifting seat 5A2 is rotatably connected to two rollers 5A3 arranged in the horizontal direction;

[0042] A lifting guide rail 5A7 is fixed on the support 5A1; a lifting slider 5A8 that is slidably connected to the lifting guide rail 5A7 is fixed on the lifting seat 5A2; the sliding connection between the lifting seat 5A2 and the support 5A1 is achieved through the lifting guide rail 5A7 and the lifting slider 5A8.

[0043] The battery cell is transported via a magnetic levitation transport rail to a position above four rollers 5A3. Simultaneously, lifting cylinders 5A9 on both sides activate, causing lifting seats 5A2 on both sides to rise. The battery cell is then supported at one end by two rollers 5A3 on one side, and at the other end by two rollers 5A3 on the other side. This four-point support stabilizes the battery cell. Then, pushing cylinders 5A6 on both sides activate, causing sliding seats 5A11 on both sides to move towards each other. Two turntables 5A4 clamp the two ends of the battery cell. Since both turntables 5A4 and rollers 5A3 rotate freely, the battery cell can still rotate around its axis after being clamped.

[0044] In addition to its supporting role during the rising or falling of the battery cell, the roller 5A3 can also rotate with the battery cell during its rolling process, and further press the tape B wrapped on the surface of the battery cell onto the surface of the battery cell through the roller 5A3.

[0045] In a preferred embodiment of the present invention, the turntable 5A4 is made of insulating material.

[0046] like Figure 3 As shown, in a preferred embodiment of the present invention, the battery cell drive assembly includes a rotating shaft 502 rotatably connected to a support 5A1 and a drive pulley 505 rotatably connected to the support 5A1; a friction wheel 501 and a driven pulley 503 are respectively fixed at both ends of the rotating shaft 502; a belt 504 is tensioned between the driven pulley 503 and the drive pulley 505; a servo motor capable of driving the drive pulley 505 to rotate is fixed on the support 5A1; after the cut tape B comes into contact with the battery cell, the friction wheel 501 abuts against the surface of the battery cell; the servo motor starts and drives the friction wheel 501 on the rotating shaft 502 to rotate through the drive pulley 505, the belt 504 and the driven pulley 503; the rotating friction wheel 501 drives the battery cell to rotate, winding the tape B held on the moving jaw 7 and wrapping it around the surface of the battery cell.

[0047] In a preferred embodiment of the present invention, the outer circumferential surface of the friction wheel 501 is covered with rubber.

[0048] In a preferred embodiment of the present invention, a frame linear module 2 and a frame slide rail 8 are fixed on the main support 6; a frame slider 9 that is slidably connected to the frame slide rail 8 is fixed on the frame 10; and the slide table of the frame linear module 2 is connected to the frame 10.

[0049] The frame linear module 2 is not fundamentally different from existing technology, so it will not be described in detail. The sliding direction of the slide table on the frame linear module 2 is set along the axial direction of the battery cell. The frame linear module 2 can drive the unwinding mechanism 1, fixed gripper 4, and movable gripper 7 on the frame 10 to move along the axial direction of the battery cell, so that the tape can be aligned with different positions of the battery cell in the axial direction. This makes it convenient to align the tape application with the required application position of the battery cell.

[0050] In a preferred embodiment of the present invention, a tape winding display panel 11 is fixed on the main support 6. The tape winding display panel 11 displays the path of the tape winding.

[0051] When using this invention, the linear module on the frame first drives the unwinding mechanism, fixed gripper, and movable gripper on the frame to move along the axial direction of the battery cell, aligning the adhesive application with the required adhesive application position on the battery cell. The tape unwound by the unwinding mechanism passes through the counterweight, tension wheel, and guide wheel, first through the two jaws of the fixed gripper, and then is clamped and fixed by the passive gripper. When the tape is pulled out, the fixed gripper releases its grip on the tape, and the movable gripper clamps and fixes the end of the tape. The linear module then drives the movable gripper to move linearly, pulling the tape out to the set length, waiting for the battery cell to enter directly above the coating module. The battery cell is transported to the top of four rollers via a magnetic levitation transport rail. The lifting cylinders on both sides are activated simultaneously, causing the lifting seats on both sides to rise. Two rollers on one side support one end of the battery cell, and two rollers on the other side support the other end of the battery cell. The four-point support stably supports the battery cell, lifting the battery cell in the magnetic levitation transport rail fixture, so that the battery cell... Separated from the fixture; the ejection cylinders on both sides are activated, driving the sliding seats on both sides to move towards each other, and the two turntables clamp the two ends of the battery cell tightly; as the battery cell continues to rise until it contacts the tape and a portion of the tape is adhered and fixed to the surface of the battery cell; the fixed gripper holds and fixes the tape, and the cutter assembly cuts the tape. The tape from the cut point to the end of the tape that contacts the battery cell automatically falls onto the surface of the battery cell and adheres and fixes it to the battery surface; the servo motor is activated, driving the friction wheel on the rotating shaft to rotate through the active pulley, belt and driven pulley; the rotating friction wheel drives the battery cell to rotate, winding the tape held on the moving gripper and wrapping it around the surface of the battery cell; during the wrapping and winding, the linear speed of the tape winding is equal to the moving speed of the moving gripper, reducing the tension on the tape and preventing the tape from being folded and stuck; after the wrapping is completed, the battery cell is lowered through the wrapping module and placed back onto the fixture; this structure can realize automatic wrapping of the battery cell, the wrapping action is simple, and the wrapping quality is more stable.

[0052] The above description is only a preferred embodiment of the present invention. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of this patent application are included in the scope of this patent application.
