[0051] As Figure 1 and Figure 2 As shown, this embodiment provides a rewinding and unwinding device 100 for rewinding or unwinding a material 300 on a roller shaft 200. The rewinding and unwinding device 100 disclosed in this embodiment can be but is not limited to production scenarios such as coating, film preparation, battery electrode sheet preparation, roll-to-roll rolling, etc., and can also be applied to other scenarios where the material 300 needs to be rewound and unwound. The roller shaft 200 can be wound with the material 300, and at this time the rewinding and unwinding device 100 is used to unwind the material 300. The roller shaft 200 can also be not wound with the material 300, and the material 300 is to be wound around itself, and at this time the rewinding and unwinding device 100 is used to wind the material 300. The material 300 can be but is not limited to various strip-shaped wound materials 300 such as films, aluminum foils, copper foils, strip steels, etc., and it can be different according to specific application fields, and will not be elaborated and limited here.

[0052] Specifically, the rewinding and unwinding device 100 includes two oppositely arranged mounting brackets 10, two clamping mechanisms 20, and two supporting mechanisms 30. The two oppositely arranged mounting brackets 10 are used to mount the material roller. The two clamping mechanisms 20 are respectively arranged on the two mounting brackets 10 and can clamp the roller shaft 200 of the material roller. The two supporting mechanisms 30 are respectively arranged on the two mounting brackets 10. Each supporting mechanism 30 includes a V-shaped bearing surface, and the V-shaped bearing surface is used to support the roller shaft 200. The supporting mechanism 30 can drive and lift the roller shaft 200 to a position flush with the clamping mechanism 20. When loading, first place both ends of the roller shaft 200 on the supporting mechanism 30, and then the supporting mechanism 30 moves the roller shaft 200 to a position flush with the clamping mechanism 20. At this time, the clamping mechanism 20 extends and moves in the direction close to the roller shaft 200 to ensure smooth insertion into the roller shaft 200, successfully loading and fixing, which is convenient for operation; it can effectively avoid the risk that when the roller shaft 200 is loaded, due to inaccurate placement and docking positions of the AGV / forklift, the roller shaft 200 and the material 300 on it fall or even injure the staff, improving safety. The V-shaped bearing surface can automatically correct the centering position of the roller shaft 200 on the supporting mechanism 30, further ensuring the accuracy of the docking between the roller shaft 200 and the clamping mechanism 20. Among them, grooves are provided at both ends of the roller shaft 200 for the clamping mechanism 20 to extend into; the clamping mechanism 20 can be any existing air chuck that can achieve the above functions; the above-mentioned position flush with the clamping mechanism 20 is the position where the axis of the roller shaft 200 and the air chuck is flush when rotating, so that the air chuck can extend into the groove.

[0053] The rewinding and unwinding device 100 further includes a rotation driving mechanism. The rotation driving mechanism is arranged at the clamping mechanism 20 at at least one end of the roller shaft 200. The rotation driving mechanism is used to drive the clamping mechanism 20 to rotate to realize the release and winding of the material 300. The rotation driving mechanism can be a driving motor.

[0054] As Figure 1 shown, the rewinding and unwinding device 100 further includes a detection mechanism 40. The detection mechanism 40 is configured to detect the remaining amount of the material 300 on the roller shaft 200. Specifically, the detection mechanism 40 includes a mounting member 41 and a second detection member 42. The mounting member 41 is arranged on the mounting bracket 10, and the second detection member 42 is mounted on the mounting member 41 and faces the side of the roller surface of the roller shaft 200. The second detection member 42 is a distance sensor, and the distance sensor can detect the distance between the distance sensor and the outermost layer of the material 300 on the roller shaft 200 to determine how much material 300 is wound on the roller shaft 200. The rewinding and unwinding device 100 further includes a control component. The distance sensor is communicatively connected to the control component and can send the distance information to the control component; the control component is communicatively connected to the rotation driving mechanism, makes a judgment after receiving the distance information, and then controls the start and stop of the rotation driving mechanism to realize the start and stop control of the rewinding and unwinding.

[0055] Combination Figures 1 - 4 The specific structure of the supporting mechanism 30 will be described. For example Figures 1 - 4 As shown, the supporting mechanism 30 includes a driving component 31 and a connecting component 32, and the V-shaped bearing surface is arranged on the connecting component 32; the connecting component 32 is connected to the output end of the driving component 31, and the driving component 31 can drive the connecting component 32 to move between a first position and a second position; when the connecting component 32 is in the first position, the V-shaped bearing surface is located on one side of the clamping mechanism 20, and the connecting component 32 is used to receive and support the roller shaft 200 at the first position. In the second position, the roller shaft 200 on the V-shaped bearing surface is coaxial with the above-mentioned air chuck, and the connecting component 32 is used to support the roller shaft 200 at the second position for the clamping mechanism 20 to clamp. When in the first position, it is convenient for the staff to load and unload the roller shaft 200; when in the second position, it is convenient for the clamping mechanism 20 to clamp the roller shaft 200.

[0056] Specifically, the driving component 31 includes a transmission member 312. The transmission member 312 is pivotally connected to the mounting frame 10 through a second shaft 314. The connecting component 32 is arranged at one end of the transmission member 312 and on one side of the second shaft 314; the connecting component 32 is used to drive the connecting component 32 to rotate around the second shaft 314, so that the connecting component 32 switches between the first position and the second position. When the connecting component 32 rotates to the first position, the connecting component 32 realizes receiving and supporting the roller shaft 200 placed between the mounting frames 10; and when rotating to the second position, the connecting component 32 sends the roller shaft 200 between the two clamping mechanisms 20 and is flush with the clamping mechanism 200.

[0057] Further, when the connecting component 32 rotates to a horizontal direction, it is in the first position. The V-shaped bearing surface on the connecting component 32 has an opening vertically upward and can be used to receive the roller shaft 200. When the connecting component 32 rotates clockwise around the second shaft 314, driving the V-shaped bearing surface and the roller shaft 200 thereon to rotate upward can reach the second position, so as to send the roller shaft 200 between the two clamping mechanisms 20 and be flush with the clamping mechanism 20, so that the clamping mechanism 20 can clamp the roller shaft 200.

[0058] The driving component 31 includes a driving member 311. The driving member 311 is pivotally connected to the mounting frame 10 through a first shaft 313 and can output linear motion; the transmission member 312 is pivotally connected to the mounting frame 10 through a second shaft 314. The output end of the driving member 311 is pivotally connected to the connecting component 32 through a third shaft. The first shaft 313, the second shaft 314, and the third shaft are arranged in parallel. During operation, the driving member 311 drives the transmission member 312 to rotate around the second shaft 314, thereby realizing the switching of the end of the transmission member 312 away from the driving member 311 between the loading position and the second position. Among them, the driving member 311 can be a cylinder.

[0059] Preferably, the connecting component 32 is detachably connected to the transmission member 312, which facilitates the quick disassembly and assembly of the connecting component 32 and the transmission member 312.

[0060] Optionally, as Figures 2 - 4 shown, the connecting component 32 includes a supporting member 321 and two sets of gasket groups 322. A V-shaped mounting surface is provided on the supporting member 321; the two sets of gasket groups 322 are oppositely mounted on the V-shaped mounting surface and form a V-shaped bearing surface. Each set of gasket groups 322 includes at least one gasket supporting member 321, and the number of gaskets in the gasket group 322 is adjustable. By adjusting the number of gaskets, the spacing of the V-shaped bearing surface is adjusted, so that the supporting member 321 can support rollers 200 with different diameters, improving the versatility of the winding and unwinding device 100.

[0061] Preferably, the gasket is detachably connected to the supporting member 321. Specifically, the gasket is detachably connected to the supporting member 321 through a fixing member, which facilitates the quick disassembly and assembly of the gasket and the supporting member 321. Among them, the fixing member is a bolt, and the bolt passes through the gasket and is threadedly connected to the supporting member 321, making the disassembly and assembly of the gasket and the supporting member 321 convenient and the connection reliable. In other embodiments, the fixing member can also be a rivet, a pin or a movable buckle, etc.

[0062] Optionally, the gasket is made of a flexible material to prevent damage to the roller 200.

[0063] Optionally, the supporting mechanism 30 further includes a first detection member, which is arranged on the supporting member 321 and is configured to detect whether a roller 200 is placed on the V-shaped bearing surface of the supporting member 321. Specifically, the first detection member is a pressure sensor, and both the pressure sensor and the driving member 311 are communicatively connected to the control component. The pressure sensor is used to transmit pressure information to the control component in real time; the control component is connected to the driving member 311, is used to receive the pressure information, and sends a control signal to the driving member 311 according to the pressure information to drive the driving member 311 to expand and contract. The automatic loading of the roller 200 is realized, reducing the potential safety hazards to the staff. It should be noted that the control component is a prior art, and any control component capable of realizing the above functions can be adopted in this embodiment.

[0064] As Figure 1 shown, the number of rollers 200 is at least two, and at least two rollers 200 are arranged at intervals in a direction perpendicular to the axis of the roller 200. Correspondingly, the number of clamping mechanisms 20 and supporting mechanisms 30 at both ends of the roller 200 is multiple groups, which can wind or unwind multiple rollers simultaneously, improving the winding and unwinding efficiency of the winding and unwinding device 100.

[0065] In order to make the mechanism of the winding and unwinding device 100 compact and prevent the supporting mechanisms 30 at adjacent two rollers 200 from interfering with each other, as Figure 1As shown, the supporting mechanisms 30 at two adjacent roller shafts 200 are arranged in opposite directions. The rewinding and unwinding device 100 further includes a flipping mechanism 50, which includes a flipping drive assembly (not shown in the figure) and a transmission gear. The flipping drive assembly drives the gear to rotate, thereby flipping the mounting frame 10 by 180°. The flipping drive assembly can be a drive motor. When loading the roller shaft 200, the roller shaft 200 is loaded onto the supporting member 321 with the V-shaped opening facing upward, and the clamping mechanism 20 clamps the roller shaft 200. Subsequently, the flipping drive assembly drives the gear to rotate, flipping the mounting frame 10 by 180° so that the other supporting member 321 has the V-shaped opening facing upward. Repeat the above actions until all the roller shafts 200 are loaded.
