This technique precisely coats the cell surface with a functional coating, optimizing properties such as insulation, voltage resistance, moisture resistance, rust prevention, and corrosion resistance. However, existing battery cells are fixed using clamping or gripper mechanisms, preventing rotation and requiring the spray gun to circle the cell during coating. This leads to two problems: first, the fixing method obstructs the coating area, necessitating secondary coating and reducing production efficiency; second, the repeated coating of the same area by the spray gun further reduces efficiency and can cause uneven coating thickness, affecting the consistency of cell performance.

[0029] Please see Figure 1 and Figure 2In this embodiment, the fixture is applied to a spraying production equipment. The fixture is used to adsorb the workpiece 50. The fixture rotates on the spraying production equipment to drive the workpiece 50 to rotate. The production equipment uses spraying technology to apply fluid to the surface of the workpiece 50, thereby realizing the spraying process of the workpiece 50. The fixture provided in this application includes a fixture base 10, a first driving mechanism, and an adsorption component 30. The first driving mechanism is disposed on the fixture base 10, and the adsorption component 30 is rotatably disposed on the fixture base 10 and connected to the first driving mechanism. The adsorption component 30 can be used to adsorb the workpiece 50 so that the workpiece 50 can rotate relative to the fixture base 10 under the drive of the first driving mechanism. In this embodiment, the workpiece 50 is a battery cell. It is understood that in other embodiments, the workpiece 50 can also be a columnar product from other industries, which is not limited here. With this design, when the battery cell needs to be coated, the adsorption component adsorbs one end of the battery cell that does not need to be coated. The adsorption component drives the battery cell to rotate under the drive of the first drive mechanism, so that the battery cell can be coated while rotating without obstruction. This is beneficial for the coating process on the side of the battery cell, thereby effectively improving the coating efficiency and coating quality.

[0030] The vacuum device may include, but is not limited to, vacuum pumps, vacuum generators, and other vacuum generating devices. It is not limited here. This embodiment uses a vacuum generator as an example.

[0031] The fixture base 10 can be a long strip fixture base 10, and there can be multiple adsorption components 30. Multiple adsorption components 30 are spaced apart on the fixture base 10 along the length direction of the fixture base 10. One adsorption component 30 adsorbs one workpiece 50, so that the fixture can adsorb multiple workpieces 50 at the same time.

[0032] Please see Figures 3 to 6 In some embodiments, in order for the first driving mechanism to drive the adsorption components 30, the first driving mechanism may include a first gear 21 and a driving component 22. The first gear 21 is rotatably mounted on the fixture base 10, and the driving component 22 is rotatably mounted on the fixture base 10 and connected to the first gear 21. Multiple adsorption components 30 are connected to the driving component 22. The first gear 21 is used to cooperate with the second driving mechanism of the production equipment to drive the driving component 22, so that the driving component 22 drives multiple adsorption components 30. It is understood that in other embodiments, a design method in which only the first driving mechanism drives the components may be adopted, and this is not limited here.

[0033] Furthermore, multiple adsorption components 30 are arranged sequentially along the length of the fixture base 10. The first gear 21 is located in the middle of the fixture base 10. There are two drive components 22, which are symmetrically arranged about the first gear 21. Multiple adsorption components 30 located on one side of the first gear 21 are connected to the drive component 22 located on the same side as the first gear 21, and multiple adsorption components 30 located on the other side of the first gear 21 are connected to the drive component 22 located on the other side of the first gear 21. That is, the first gear 21 drives the two drive components 22 for transmission, and the two drive components 22 then drive the multiple adsorption components 30 to rotate respectively.

[0034] Furthermore, to simultaneously drive multiple adsorption components 30, the driving component 22 may include multiple second gears 221 and a transmission belt 222. The multiple second gears 221 are rotatably mounted on the fixture base 10, and the transmission belt 222 is wound around the outer periphery of the multiple second gears 221. One of the second gears 221 is coaxially connected to the first gear 21, and the multiple adsorption components 30 are correspondingly connected to the second gears 221. With this design, since one of the second gears 221 is coaxially arranged with the first gear 21, the second gear 221 rotates under the drive of the first gear 21, which on the one hand drives the adsorption component 30 to rotate, and on the other hand drives the transmission belt 222 to drive the other second gears 221 to rotate, thereby causing the other second gears 221 to drive the adsorption component 30 to rotate.

[0035] It is understood that, in addition to the gear + belt transmission method exemplified in this embodiment, the drive component 22 can also adopt other transmission methods such as gear + gear, gear + rack, magnetic wheel rotation, synchronous wheel rotation, and friction rotation, which are not limited here.

[0036] In some embodiments, the first drive mechanism may further include a tensioning mandrel component 23 and an idler pulley component 24. The tensioning mandrel component 23 is located outside the drive belt 222 and presses against the drive belt 222, while the idler pulley component 24 is located inside the drive belt 222 and presses against the drive belt 222. With this design, the drive belt 222 is pressed along a detour by the idler pulley component 24 and the tensioning mandrel component 23, thereby achieving tension on the drive belt 222.

[0037] The tensioning mandrel component 23 is mounted on the adjusting block and the clamping degree can be adjusted by adjusting the screw to ensure that the second gear 221 rotates synchronously and in a coordinated manner.

[0038] In some embodiments, to provide negative pressure for adsorbing the workpiece 50 to the adsorption assembly 30, the fixture base 10 may be provided with a vacuum chamber 113, which is connected to the adsorption assembly 30. The fixture may also include a vacuum connector component, which is located on the fixture base 10 and connected to the vacuum chamber 113, and can be used to connect to the vacuum device of the production equipment to provide negative pressure. It is understood that in other embodiments, a vacuum device may be provided on the fixture, which is not limited here.

[0039] The vacuum device may include, but is not limited to, vacuum pumps, vacuum generators, and other vacuum generating devices. It is not limited here. This embodiment uses a vacuum generator as an example.

[0040] In addition, when the vacuum connector component is connected to the vacuum device of the production equipment, it can also be quickly coupled to the output end of the power source such as the linear motor and cylinder used to drive the fixture to move on the production equipment. The precise displacement of the fixture is achieved through mechanical insertion. This component innovatively integrates vacuum adsorption and power transmission functions, thereby simplifying the structure of the fixture.

[0041] Please see Figure 6 and Figure 7 In some embodiments, the adsorption assembly 30 may include a pneumatic slip ring 31 and a suction cup component 32. The pneumatic slip ring 31 may include a fixed portion 311 and a rotating portion 312. The fixed portion 311 is disposed on the fixture base 10, and the rotating portion 312 is rotatably connected to the fixed portion 311. The suction cup component 32 is fixed to the rotating portion 312 and connected to a first driving mechanism. The rotating portion 312 can drive the suction cup component 32 to rotate relative to the fixed portion 311 under the drive of the first driving mechanism. The fixed portion 311 communicates with the vacuum chamber 113 and the suction cup component 32, and the suction cup component 32 is used to adsorb the workpiece 50. With this design, the rotating portion 312 is used for power transmission, and the fixed portion 311 is used for vacuum gas transmission. Continuous vacuum gas transmission in the rotating state is achieved through the precision sealing structure between the fixed portion 311 and the rotating portion 312, preventing leakage. Specifically, the fixed portion 311 is provided with a quick connector, which is connected to the vacuum chamber 113 through an air pipe 33.

[0042] Furthermore, the suction cup component 32 may also include a suction cup base 321, a suction cup cup 322, and a sealing suction cup 323. The suction cup base 321 is fixed to the rotating part 312, the suction cup cup 322 is disposed on the suction cup base 321, and the sealing suction cup 323 is disposed on the suction cup cup 322. The fixed part 311, the suction cup base 321, the suction cup cup 322, and the sealing suction cup 323 are connected in sequence. The sealing suction cup 323 is used to adsorb the workpiece 50.

[0043] Furthermore, the suction cup component 32 may also include a first sealing ring 325, which is disposed around the outer periphery of the sealing suction cup 323 to abut against the workpiece 50 when the sealing suction cup 323 adsorbs the workpiece 50. With this design, the first sealing ring 325 can improve the sealing performance between the workpiece 50 and the sealing suction cup 323, thereby improving the reliability of the adsorption assembly 30 in adsorbing the workpiece 50.

[0044] Among them, the suction cup 322 is made of stainless steel or other rigid materials that do not stick to paint and have a certain degree of support.

[0045] The sealing suction cup 323 includes, but is not limited to, polyurethane with a hardness value of 40 to 50 degrees, or other soft non-metallic materials with good sealing properties, which are embedded in the suction cup cup 322. Its upper surface that directly contacts the battery cell is 0.2 mm higher than the suction cup cup, thus avoiding direct metal contact with the battery cell; its top surface area is smaller than the bottom area of ​​the product battery cell.

[0046] In some embodiments, the suction cup component 32 may further include a collection groove 324, which is arranged around the outer periphery of the suction cup base 321 and can be used to collect paint dripping from the workpiece 50. The collection groove 324 on the outer periphery of the suction cup base 321 for collecting paint dripping from the workpiece 50 can cover the components below, preventing paint from dripping onto the components and affecting their normal movement. It also prevents paint from contaminating the working area, reducing safety hazards, preventing paint from penetrating the equipment interior to extend its service life, reducing secondary contamination of the workpiece 50 by paint, and improving processing efficiency. This achieves multiple benefits, including environmental cleanliness, equipment protection, quality improvement, and paint management.

[0047] In some embodiments, considering that the fixture needs to be transported between different workstations during use, the vacuum connector components may include a first vacuum connector component 41 and a second vacuum connector component 42. The first vacuum connector component 41 can be used to connect to the vacuum device of the corresponding production equipment workstation, and the second vacuum connector component 42 can be used to connect to the vacuum device of the corresponding production equipment conveying mechanism. With this design, when the fixture is at the production equipment workstation, the first vacuum connector component 41 is connected to the vacuum device of the corresponding production equipment workstation to continuously and stably provide a vacuum to the adsorption component 30 during processing at that workstation; when the fixture is moving on the production equipment, the second vacuum connector component 42 is connected to the vacuum device of the corresponding production equipment conveying mechanism to continuously and stably provide a vacuum to the adsorption component 30 during the movement.

[0048] Furthermore, considering that some production equipment conveying mechanisms may include multiple spaced sub-conveyor mechanisms, the second vacuum connector component 42 may include a third vacuum connector component 421 and a fourth vacuum connector component 422. The third vacuum connector component 421 can be used to connect to a vacuum device of the corresponding sub-conveyor mechanism, and the fourth vacuum connector component 422 can be used to connect to a vacuum device at the interval between two adjacent conveyor mechanisms, thereby enabling the entire production equipment conveying mechanism to stably provide a vacuum. Specifically, the first vacuum connector component 41 and the fourth vacuum connector component 422 are located on the top of the fixture base 10, and the third vacuum connector component 421 is located on the bottom of the fixture base 10.

[0049] Please see Figure 8 In some embodiments, the vacuum connector component may include a valve seat 43 and a valve stem 44. The valve seat 43 is disposed on the fixture base 10 and has a first hollow channel communicating with the vacuum chamber 113. The valve stem 44 is movably disposed within the first hollow channel and has a second hollow channel communicating with the vacuum device. The valve stem 44 is used to move under the push of the vacuum device until the second hollow channel communicates with the first hollow channel, so that the vacuum device is in an open state. Figure 8 As shown in (a), or, when the vacuum device is removed, it moves to the point where the second hollow channel and the first hollow channel are not connected, so that the vacuum device is in a self-locking state, as shown in (a). Figure 8 As shown in (b). With this design, when the fixture is at the production equipment station, the first vacuum connector component 41 is in the open state and connected to the vacuum device of the corresponding production equipment station, so that the fixture is in a vacuum state, and the second vacuum connector component 42 is in a self-locking state, so that the fixture can maintain pressure; similarly, when the vacuum adsorption fixture is flowing on the production equipment, the second vacuum connector component 42 is in the open state and connected to the vacuum device of the corresponding production equipment conveying mechanism, so that the fixture is in a vacuum state, and the first vacuum connector component 41 is in a self-locking state, so that the fixture can maintain pressure.

[0050] Furthermore, in order for the vacuum connector component to return to the pressure-holding self-locking state after being separated from the vacuum device, the vacuum connector component may also include an elastic reset member 45. One end of the elastic reset member 45 abuts against the inner wall of the valve seat 43 and the other end abuts against the valve stem 44. Under the push of the vacuum device, the elastic reset member 45 is compressed by the valve stem 44. When the vacuum device is removed, the elastic reset member 45 extends to drive the valve stem 44 to reset.

[0051] Furthermore, the vacuum connector component may also include a second sealing ring 46, which is sleeved on the valve stem 44 and abuts against the inner wall of the valve seat 43 to ensure the sealing performance of the vacuum connector component.

[0052] In addition, the valve seat 43 is provided with a through hole 431 that communicates with its interior. The through hole 431 is used for venting and air intake, so that the installation position of the elastic reset member 45 is connected to the outside air and a vacuum cavity 113 is not formed, which is conducive to the smooth operation of the downward pressing and upward springing action.

[0053] Both the second vacuum connector component 42 and the first vacuum connector component 41 can be one-way valves, so that both the second vacuum connector component 42 and the first vacuum connector component 41 can be in an open state and a self-locking state.

[0054] like Figure 6 As shown, in some embodiments, in order to install the first gear 21, the driving component 22 and the multiple adsorption components 30 on the fixture base 10, the fixture base 10 may include a mounting plate 11 and a mounting frame 12. The first gear 21 is rotatably disposed at the bottom of the mounting plate 11, the driving component 22 is located at the top of the mounting plate 11 and passes through the mounting plate 11 to be connected to the first gear 21, the mounting frame 12 covers the driving component 22, the driving component 22 is rotatably connected to the mounting frame 12, and the multiple adsorption components 30 are rotatably disposed on the mounting frame 12.

[0055] Furthermore, the mounting plate 11 may include a base plate 111 and a cover plate 112, the cover plate 112 and the base plate 111 being joined together to form a vacuum chamber 113, the adsorption assembly 30 being disposed on the cover plate 112, the first vacuum connector component 41 and the fourth vacuum connector component 422 being disposed on the cover plate 112, and the third vacuum connector component 421 being disposed on the base plate 111.

[0056] This application provides a fixture including a fixture base 10, a first driving mechanism, and an adsorption component 30. The first driving mechanism is disposed on the fixture base 10, and the adsorption component 30 is rotatably disposed on the fixture base 10 and connected to the first driving mechanism. The adsorption component 30 can be used to adsorb a workpiece 50, so that the workpiece 50 is rotated relative to the fixture base 10 under the drive of the first driving mechanism. In this embodiment, the workpiece 50 is a battery cell. It is understood that in other embodiments, the workpiece 50 can also be a columnar product from other industries, which is not limited here. With this design, when the battery cell needs to be coated, the adsorption component adsorbs one end of the battery cell that does not need to be coated. The adsorption component drives the battery cell to rotate under the drive of the first driving mechanism, so that the battery cell can be rotated and coated without obstruction, which is beneficial for the coating process on the side of the battery cell, thereby effectively improving the coating efficiency and coating quality of the battery cell.
