[0032] The present invention will now be further described with reference to the accompanying drawings:

[0033] like Figures 1 to 3 As shown, the technical solution adopted by the present invention is as follows: a battery cell roll forming and coating device, comprising a support 11, the support 11 being horizontally arranged, and a vertical support plate provided thereon, characterized in that: it further comprises a transmission mechanism 1, a roll forming mechanism 2, an upper pressing mechanism 3, a top support mechanism 4, and an end pressing mechanism 5, wherein,

[0034] The upper pressing mechanism 3 and the top supporting mechanism 4 are arranged at intervals above and below each other and are respectively connected to the transmission mechanism 1, and are driven by the transmission mechanism 1 to move up and down respectively.

[0035] The roller pressing mechanism 2 is located on one side of the gap between the upper pressing mechanism 3 and the top support mechanism 4. The roller pressing mechanism 2 is connected to the transmission mechanism 1 and is driven by the transmission mechanism 1 to move up and down so as to wrap the adhesive paper that is horizontally adhered to the upper surface of the battery cell downward to the end face of the battery cell. The transmission mechanism 1 drives the roller pressing mechanism 2 to move horizontally so as to continue to wrap the adhesive paper on the end face of the battery cell to the lower surface of the battery cell.

[0036] The end-pressing mechanism 5 is located on one side of the gap between the upper pressing mechanism 3 and the top support mechanism 4. The end-pressing mechanism 5 is driven by the transmission mechanism 1 to move horizontally close to the adhesive paper on the end face of the battery cell, and moves up and down to slide into the lower surface of the battery cell, so as to maintain pressure on the adhesive paper on the end face and the lower surface of the battery cell.

[0037] The application realizes a power output through a cam cooperating with its transmission mechanism to drive the roll pressing mechanism 2, the upper pressing mechanism 3, the supporting mechanism 4 and the end pressing mechanism 5 to complete the battery cell rubberizing, supporting, roll pressing and rubberizing and pressure maintaining actions respectively, effectively improving the battery cell roll pressing and rubberizing device. The application is used for solving the problem of automatic rubberizing of battery cells. The application integrally designs the transmission mechanism 1, the roll pressing mechanism 2, the upper pressing mechanism 3, the supporting mechanism 4 and the end pressing mechanism 5. The supporting mechanism 4 supports the battery cell from below, the upper pressing mechanism 3 horizontally attaches the rubber paper to the upper surface of the battery cell, and the rubber paper is horizontally extended to the outside of the battery cell. After the rubber paper attached to the upper surface of the battery cell is rolled and flattened by the roll pressing mechanism 2, the roll pressing mechanism 2 bends and covers the horizontally extended rubber paper to the vertical end surface of the battery cell, and then re-bends the rubber paper to the horizontal direction and rolls it to the lower surface of the battery cell. The end pressing mechanism 5 presses the rubberized battery cell from the outside of the vertical end surface to the vertical end surface and the lower surface of the battery cell to maintain the pressure of the rubberized rubber paper. Thus, the horizontal rubber paper is automatically bent and rolled to the upper surface, the vertical end surface and the lower surface of the battery cell, and the rubberized rubber paper is automatically maintained. The roll pressing mechanism 2, the upper pressing mechanism 3, the supporting mechanism 4 and the end pressing mechanism 5 are integrally designed on both sides of the vertical support plate vertically arranged on the support 11, and the transmission shaft horizontally arranged at the lower part of the vertical support plate and penetrating through both sides of the vertical support plate is used as the power output execution component. The multiple cams arranged at intervals on the transmission shaft 13 correspond to the roll pressing mechanism 2, the upper pressing mechanism 3, the supporting mechanism 4 and the end pressing mechanism 5. During the rotation of the transmission shaft 13, the multiple cams are driven to rotate synchronously, and the multiple cams are designed to have different structures and external dimensions to drive the roll pressing mechanism 2 to move vertically and horizontally, drive the upper pressing mechanism 3 and the supporting mechanism 4 to move vertically, and drive the end pressing mechanism 5 to move horizontally. The above mechanisms complete the actions in sequence. Thus, only one power mechanism drives four rubberizing execution mechanisms to complete the automatic rubberizing according to the rubberizing process action sequence. Compared with the existing rubberizing equipment, the mode of multiple power output supporting transmission mechanisms and single power output transmission can more effectively reduce the transmission difference of rubberizing actions, ensure the stability of rubberizing actions, and greatly reduce the equipment cost and rubberizing production cost.

The transmission shaft 13 is arranged in parallel and at intervals on one side of the output shaft of the motor 12, and is connected with the output shaft of the motor 12 through a transmission belt. The cam set includes at least two cams, which are fixed at intervals on the transmission shaft 13 and are driven by the transmission shaft 13 to rotate synchronously.

[0039] The upper pressing mechanism 3 and the jacking mechanism 4 are connected with the cam set and driven to move up and down respectively by the cam set;

[0040] The roller pressing mechanism 2 is connected with the cam set and driven to move up and down by the cam, so as to wrap the adhesive tape adhered to the upper surface of the battery cell downward to the end surface of the battery cell, and the cam drives the roller pressing mechanism 2 to move horizontally, so as to continue wrapping the adhesive tape on the end surface of the battery cell to the lower surface of the battery cell;

[0041] The end pressing mechanism 5 is driven by the cam set to move horizontally close to the adhesive tape on the end surface of the battery cell, and to move up and down to slide into the lower surface of the battery cell, so as to keep the pressure of the adhesive tape on the end surface and the lower surface of the battery cell.

[0042] As shown in Figure 3 and Figure 6 The cam set of the present application comprises a first cam 14, a second cam 15, a third cam 16, a fourth cam 17 and a fifth cam 18 arranged at intervals on the transmission shaft 13.

[0043] The transmission shaft 13 of the present application is driven by the motor 12 to drive the first cam 14, the second cam 15, the third cam 16, the fourth cam 17 and the fifth cam 18 to move synchronously.

[0044] As shown in Figure 1 and Figure 6 The present application is provided with a vertical support plate vertically arranged on the support 1.

[0045] The present application takes the vertically arranged vertical support plate as the support bearing structure, the roller pressing mechanism 2 and the upper pressing mechanism 3 are arranged on one side of the vertical support plate, and the jacking mechanism 4 and the end pressing mechanism 5 are arranged on the other side of the vertical support plate.

[0046] As shown in Figure 3As shown, the upper pressing mechanism 3 of the present application comprises a first roller 31, a first lifting slide 32, a first spring 33, a second roller 34, a first shifting rod 35, a third roller 36, an upper pressing slide 37 and an upper pressing block 38, wherein the first lifting slide 32 is slidably arranged on one side of the vertical support plate in the vertical direction and connected with the side wall of the vertical support plate through the first spring 33 arranged vertically; the first roller 31 is rotatably connected on the first lifting slide 32 and located above the first cam 14, and the first lifting slide 32 is driven to move up and down by the first roller 31 when the first cam 14 rotates; the upper pressing slide 37 is arranged on the side of the first lifting slide 32 and slidably connected with the side wall of the vertical support plate in the vertical direction; the first shifting rod 35 is arranged between the first lifting slide 32 and the upper pressing slide 37 and rotatably connected with the side wall of the vertical support plate, and strip-shaped sliding grooves are formed at both ends of the first shifting rod 35; the second roller 34 and the third roller 36 are rotatably arranged on the side walls of the first lifting slide 32 and the upper pressing slide 37 respectively and embedded in the strip-shaped sliding grooves at both ends of the first shifting rod 35 and freely slide in the strip-shaped sliding grooves; the upper pressing slide 37 is driven to move reversely by the first shifting rod 35 when the first lifting slide 32 moves up and down; and the upper pressing block 38 is reversibly slidably connected with the side wall of the upper pressing slide 37 in the vertical direction and fixed with the side wall of the upper pressing slide 37 through a screw rod.

[0047] When the transmission shaft 13 drives the first cam 14 to rotate, the first cam 14 drives the first lifting slide 32 to move up and down along the side wall of the vertical support plate through the first roller 31, the first lifting slide 32 drives the upper pressing slide 37 to move up and down in the opposite direction of the first lifting slide 32 through the first shifting rod 35 rotatably arranged on the side wall of the vertical support plate, and the upper pressing slide 37 drives the upper pressing block 38 to move so that the upper pressing block 38 presses the horizontally attached adhesive paper from above the battery cell to be tightly pressed, so that the subsequent rolling mechanism can carry the suspended clamped battery cell part to be coated with adhesive from above when rolling and coating on the bottom surface of the battery cell, avoiding the deformation of the battery cell caused by pressure when rolling and coating. At the same time, through the strip-shaped sliding grooves formed at both ends of the first shifting rod, the first lifting slide 32 and the upper pressing slide 37 are embedded in the strip-shaped sliding grooves at both ends of the first shifting rod through the second roller 34 and the third roller 36 respectively, so that the second roller 34 and the third roller 36 slide in the strip-shaped sliding grooves respectively during the rotation of the first shifting rod 35, avoiding the movement interference between the first shifting rod 35 and the first lifting slide 32 or the upper pressing slide 37 when the first shifting rod 35 rotates.

[0048] As Figure 6As shown, the top supporting mechanism 4 of the present application comprises a fourth roller 41, a second lifting slide 42, a fifth roller 43, a second shifting rod 44, a sixth roller 45, a top supporting slide 46, a second spring 47 and a top supporting block 48, wherein the second lifting slide 42 is slidably arranged on the other side of the vertical supporting plate in the vertical direction; the fourth roller 41 is rotatably connected to the side wall of the second lifting slide 42 and is located above the third cam 16, when the third cam 16 rotates, the second lifting slide 42 is driven to move up and down by the fourth roller 41; the top supporting slide 46 is arranged on one side of the second lifting slide 42 and is slidably connected to the other side wall of the vertical supporting plate in the vertical direction and is connected to the vertical supporting plate by the second spring 47 arranged vertically; the second shifting rod 44 is arranged between the second lifting slide 42 and the top supporting slide 46 and is rotatably connected to the other side wall of the vertical supporting plate, and strip-shaped sliding grooves are formed at both ends of the second shifting rod 44; the fifth roller 43 and the sixth roller 45 are rotatably connected to the side walls of the second lifting slide 42 and the top supporting slide 46 respectively and are embedded in the strip-shaped sliding grooves at both ends of the second shifting rod 44 and can slide freely in the strip-shaped sliding grooves; when the second lifting slide 42 moves up and down, the top supporting slide 46 is driven to move in the opposite direction by the second shifting rod 44; the top supporting block 48 is arranged on the top supporting slide 46.

[0049] When the transmission shaft 13 drives the third cam 16 to rotate, the third cam 16 drives the second lifting slide 42 to move up and down along the other side wall of the vertical supporting plate through the fourth roller 41, the second lifting slide 42 is driven to rotate through the second shifting rod 44 rotatably arranged on the other side wall of the vertical supporting plate, thereby driving the top supporting slide 46 to move up and down in the opposite direction of the second lifting slide 42, the top supporting slide 46 drives the top supporting block 48 to move up and down, so as to support the part to be coated of the suspended clamped battery cell from below, to provide bearing capacity from below, to avoid the deformation of the suspended battery cell caused by the roll pasting pressure on the upper surface of the battery cell during the coating process of the battery cell. In addition, the same as the first shifting rod 35, strip-shaped sliding grooves are also formed at both ends of the second shifting rod 44, the second lifting slide 42 and the top supporting slide 46 are connected to the second shifting rod 44 by embedding the fifth roller 43 and the sixth roller 45 in the strip-shaped sliding grooves, and the fifth roller 43 and the sixth roller 45 slide in the strip-shaped sliding grooves during the rotation of the second shifting rod 44, thereby avoiding the motion interference between the second shifting rod 44 and the second lifting slide 42 or the top supporting slide 46 during the rotation of the second shifting rod 44.

[0050] As shown, Figure 6As shown, the roller pressing mechanism 2 and end pressing mechanism 5 of the present invention include a lifting assembly, which includes a seventh roller 25 and a third lifting slide 26. The third lifting slide 26 is slidably disposed on the other side wall of the vertical support plate in the vertical direction. The seventh roller 25 is rotatably connected to the third lifting slide 26 and is located above the fourth cam 17. When the fourth cam 17 rotates, it drives the third lifting slide 26 to move up and down through the seventh roller 25.

[0051] Unlike the upper pressing mechanism 3 and the top supporting mechanism 4, which only involve vertical movement, the roller pressing mechanism 2 and the end pressing mechanism 5 of this invention need to move in the horizontal direction so that the roller pressing mechanism 2 can roll the adhesive paper on the upper or lower surface of the battery cell, or the end pressing mechanism 5 can extend horizontally under the battery cell to maintain pressure. Based on the above requirements, this invention uses the fourth cam 17 provided on the transmission shaft 13 to drive the seventh roller to move the third lifting slide 26 up and down on the other side wall of the vertical support plate; the third lifting slide 26 serves as the power transmission component for the roller pressing mechanism 2 and the end pressing mechanism 5 in the vertical direction.

[0052] like Figures 3 to 4 As shown, the roller pressing mechanism 2 of the present invention further includes an eighth roller 21, a roller pressing horizontal slide 22, a third spring 23, a horizontal connecting seat 24, a vertical connecting seat 27, a connecting slide 28, a ninth roller 29, a roller pressing seat 210, and a roller pressing head. The roller pressing horizontal slide 22 is slidably connected to one side wall of the vertical support plate in the horizontal direction and is connected to the vertical support plate via the third spring 23. The eighth roller 21 is rotatably connected to the roller pressing horizontal slide 22 and is located on the side of the second cam 15. When the second cam 15 rotates, it drives the roller pressing horizontal slide 22 to move horizontally in a straight line via the eighth roller 21. The horizontal connecting seat 24 is vertically fixed to the roller pressing horizontal slide 22 and has a strip-shaped groove formed on it in the vertical direction. The vertical connecting seat 27 is horizontally connected to the third lifting slide. The connecting slide 28 is slidably connected to the side wall of the vertical connecting seat 27 located on one side of the vertical support plate in the horizontal direction, and is connected to the vertical connecting seat 27 by a spring; the ninth roller 29 is rotatably disposed on the side wall of the connecting slide 28 and embedded in the strip-shaped groove on the horizontal connecting seat 24, and moves freely in the strip-shaped groove; the roller pressing seat 210 is disposed on the side wall of the connecting slide 28; the roller pressing head is disposed on the roller pressing seat 210; the horizontal connecting seat 24 drives the connecting slide 28 to move linearly in the horizontal direction through the ninth roller 29; the vertical connecting seat 27 drives the connecting slide 28 to move linearly in the vertical direction, and slides in the strip-shaped groove through the ninth roller 29 to avoid motion interference.

[0053] The transmission shaft 13 of the present invention drives the second cam 15 to rotate, and the second cam 15 drives the roller pressing horizontal slide 22 to move horizontally linearly along one side wall of the vertical support plate via the eighth roller 21. Simultaneously, as... Figure 4 As shown, a through groove is provided on the side wall of the vertical support plate. A vertical connecting seat 27 is fixed to the side of the third lifting slide 26 near the vertical support plate. The vertical connecting seat 27 extends from the other side of the vertical support plate to one side of the vertical support plate through the through groove. When the third lifting slide 26 moves up and down, it drives the vertical connecting seat 27 connected to it to move up and down within the through groove. A connecting slide 28 is slidably connected to the vertical connecting seat 27 in the horizontal direction. The connecting slide 28 moves up and down with the vertical connecting seat 27. Figure 3 As shown, the connecting slide 28 extends horizontally to the roller pressing horizontal slide 22, and a ninth roller 29 is rotatably mounted on the side wall of the connecting slide 28. A connecting seat 24 is provided on the roller pressing horizontal slide 22, and a vertically formed strip-shaped groove is formed on the connecting seat 24. The connecting slide 28 is embedded into the strip-shaped groove of the connecting seat 24 via the ninth roller 29 and slides freely within the strip-shaped groove. This achieves the connection between the roller pressing horizontal slide 22 and the connecting slide 28. The roller pressing horizontal slide 22 drives the connecting slide 28 to move horizontally via the ninth roller 29. Simultaneously, the connecting slide 28 also moves up and down with the vertical connecting seat 27. During the up and down movement, the connecting slide 28 slides within the vertically formed strip-shaped groove via the ninth roller 29, thus avoiding motion interference with horizontal movement. This structure enables the connecting slide 28 to move vertically and horizontally, thereby driving the roller pressing head mounted on the connecting slide 28 to move horizontally and vertically.
