[0012] As an optional embodiment, the mounting bracket includes:
[0013] Support frame;

[0023] During the feeding process, production personnel do not need to align the material cylinder with the chuck beforehand. An automated guided vehicle can directly place the material cylinder containing the roll onto the rollers.

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.
[0037] In related technologies, the chucks of unwinding and winding equipment generally use air-expansion clamping to clamp the electrode cylinder. However, the clamping force of the chuck is limited. On high-speed production equipment, the cylinder and the chuck slippage is serious, resulting in severe wear of the chuck and cylinder, and an increased equipment failure rate.
[0038] To address the aforementioned issues, this application provides a chuck device for a winding and unwinding equipment. By setting positioning and limiting components, the device enables alignment between the material cylinder and the chuck, preventing slippage between the material cylinder and the chuck, reducing equipment failure rate, and improving production efficiency.
[0039] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.
[0040] See Figure 1 and Figure 5 This application provides a chuck device for a winding and unwinding equipment, including a supporting mechanism 1 and a clamping mechanism 3. The supporting mechanism 1 includes a bracket 10 and a roller 11 rotatably mounted on the bracket 10 for supporting a material cylinder 2. After the material cylinder 2 is loaded, it can be pressed against the roller 11. See also... Figure 3 and Figure 4 Roller 11 can drive the material cylinder 2 to rotate at a first preset angle (from Figures 3 to 4 (The material cylinder 2 has rotated); the clamping mechanism 3 includes a movable frame 30 spaced apart from the bracket 10 along the axial direction of the material cylinder 2, and a chuck 31 rotatably disposed on the movable frame 30; the chuck 31 extends along the axial direction of the material cylinder 2, and a positioning member 32 is provided at one end of the chuck 31 facing the material cylinder 2, the positioning member 32 can rotate with the chuck 31 by a second preset angle; and when the material cylinder 2 rotates by a first preset angle and the positioning member 32 rotates by a second preset angle, the positioning member 32 is correspondingly disposed with the limiting member 20 of the material cylinder 2.
[0041] In this embodiment, the roll of material on the material cylinder 2 can be electrode roll, diaphragm roll, foil roll, etc., and this application does not limit it.
[0042] In this embodiment, the first preset angle and the second preset angle can be the same or different. For example, the first preset angle and the second preset angle can both be 90 degrees, or the first preset angle can be 90 degrees and the second preset angle can be 80 degrees. It is sufficient that when the barrel 2 rotates by the first preset angle and the positioning member 32 rotates by the second preset angle, the positioning member 32 and the limiting member 20 of the barrel 2 are correspondingly positioned. The corresponding positioning member 32 and the limiting member 20 of the barrel 2 can specify that the positioning member 32 and the limiting member 20 face each other, and that the positioning member 32 and the limiting member 20 can achieve a limiting engagement after moving closer to each other.
[0043] During the feeding process, production personnel do not need to align the material cylinder 2 with the chuck 31 beforehand. For example, an automated guided vehicle can place the material cylinder 2, loaded with the material roll, directly onto the roller 11. Supported by the bracket 10, the roller 11 drives the material cylinder 2 to rotate by a first preset angle. After the material cylinder 2 stops rotating, the positioning component 32 rotates with the chuck 31 by a second preset angle. After the positioning component 32 stops rotating, it is aligned with the limiting component 20 of the material cylinder 2, allowing them to achieve a limiting engagement after moving closer together. This achieves accurate positioning of the material cylinder 2 and the chuck 31, improving the success rate of material roll feeding, enhancing the stability and neatness of roll winding and unwinding, and thus ensuring the quality of the roll. Simultaneously, it also contributes to the automation of the winding and unwinding mechanism.
[0044] As an optional embodiment, see Figures 2 to 4 The clamping device also includes a first detection mechanism 4, which is mounted on the bracket 10 and adapted to detect the rotation angle of the material cylinder 2.
[0045] In this embodiment, the first detection mechanism 4 can be a position sensor. The position sensor detects the rotation angle of the limiting member 20 on the material cylinder 2. When the limiting member 20 on the material cylinder 2 rotates by a first preset angle, it indicates that the limiting member 20 has rotated to the target position, and the material cylinder 2 can be controlled to stop rotating.
[0046] As an optional embodiment, the chuck device further includes a second detection mechanism (not shown in the figure), which is adapted to detect the rotation angle of the chuck 31.
[0047] In this embodiment, the second detection mechanism can also be a position sensor. The position sensor detects the rotation angle of the positioning member 32 on the chuck 31. When the positioning member 32 on the chuck 31 rotates to a second preset angle, it indicates that the positioning member 32 has rotated to the target position, and the chuck 31 can be controlled to stop rotating.
[0048] As an optional embodiment, see Figure 1 and Figure 2 The bracket 10 includes a fixed frame 100 and a movable frame 101. The fixed frame 100 is rotatably provided with rollers 11. The movable frame 101 is provided on the fixed frame 100 and can move up and down on the fixed frame 100 to move towards or away from the material cylinder 2. The movable frame 101 is provided with a limiting groove 102 that cooperates with the limiting groove 102. When the movable frame 101 moves towards the material cylinder 2, the movable frame 101 lifts the material cylinder 2 through the limiting groove 102, so that the material cylinder 2 is separated from the rollers 11.
[0049] In this embodiment, the bracket 10 can be composed of a fixed part and a movable part. The fixed part includes a fixed frame 100, and the movable part includes a movable frame 101. The fixed frame 100 supports the roller 11 to support the material cylinder 2. The movable frame 101 can move up and down on the fixed frame 100 to move towards or away from the material cylinder 2. When the positioning member 32 is aligned with the limiting member 20 of the material cylinder 2 by rotating the roller 11, the movable frame 101 can move towards the material cylinder 2. At this time, the fixed frame 100 remains stationary, and the movable frame 101 extends so that the limiting groove 102 is located above the roller 11, lifting the material cylinder 2. The material cylinder 2 is separated from the roller 11, and is no longer supported by the roller 11, but by the movable frame 101, achieving precise alignment between the material cylinder 2 and the chuck 31. This facilitates accurate alignment of the positioning member 32 of the chuck 31 with the limiting member 20 of the material cylinder 2, ensuring the success rate of feeding and guaranteeing the quality of the rolled material.
[0050] As a preferred embodiment, see Figure 2 The fixed frame 100 includes a support frame 1000, a support shaft 1001, and a fixed seat 1002. One end of the support shaft 1001 can extend and retract along the axial direction of the material cylinder 2, and the other end is connected to the support frame 1000 and is used to drive the support frame 1000 to move along the axial direction of the material cylinder 2. The fixed seat 1002 is located at the bottom end of the support frame 1000, and a roller 11 is rotatably provided on the fixed seat 1002. The movable frame 101 is located on the fixed seat 1002 and can move up and down on the fixed seat 1002.
[0051] In this embodiment, the support frame 1000 can be connected to the frame 5 of the winding and unwinding equipment, and the support shaft 1001 can be connected to the side plate of the winding and unwinding equipment. Through the telescopic movement of the support shaft 1001, the support frame 1000 moves along the axial direction of the material cylinder 2, thereby adjusting the distance between the roller 11 and the material cylinder 2 to accommodate different sizes of material rolls. A fixed seat 1002 is provided at the bottom of the support frame 1000 to support the roller 11, thereby supporting the material cylinder 2 and ensuring stable rotation of the material cylinder 2 on the roller 11.
[0052] In this embodiment, the side of the support frame 1000 away from the fixed base 1002 can be used to connect to the frame 5, and the side of the support frame 1000 away from the fixed base 1002 can be arc-shaped to fit the frame 5, so as to reduce the weight of the support frame 1000 and improve the integration of the equipment.
[0053] As a preferred embodiment, see Figure 1 and Figure 2The bracket 10 also includes a first drive mechanism 103, which is mounted on the fixed base 1002. The drive end of the first drive mechanism 103 is connected to the movable frame 101 and is used to drive the movable frame 101 to move up and down on the fixed base 1002.
[0054] In this embodiment, a first drive mechanism 103 is provided on the fixed base 1002, so that the first drive mechanism 103 is fixed to the fixed base 1002 and does not move with the movable frame 101. This realizes the integration of the roller 11 for supporting the material cylinder 2 and the first drive mechanism 103 for driving the movable frame 101 to move up and down on the fixed base 1002, thereby improving the working efficiency of the equipment.
[0055] In this embodiment, the first drive mechanism 103 can be a servo motor, cylinder, etc., and this application does not limit it.
[0056] As a preferred embodiment, see Figure 3 and Figure 4 The bracket 10 also includes a second drive mechanism 104, which is disposed on the fixed base 1002. The drive end of the second drive mechanism 104 is connected to the roller 11 and is used to drive the roller 11 to rotate on the fixed base 1002.
[0057] In this embodiment, two rollers 11 can be arranged side by side, and the upper surfaces of the two rollers form an arc-shaped support surface adapted to the material cylinder 2 to improve the support force on the material cylinder 2. The rotation shaft of the roller 11 can mesh with a gear, and the drive end of the second drive mechanism 104 is connected to the gear to drive the gear to rotate, thereby driving the roller 11 to rotate.
[0058] In this embodiment, the second drive mechanism 104 can be a servo motor, cylinder, etc., and this application does not limit it.
[0059] As a preferred embodiment, see Figure 2 The movable frame 101 includes a vertically arranged movable seat 1010 and a support 1011 extending along the axial direction of the material cylinder 2 and connected to the top of the movable seat 1010. A limiting groove 102 is provided on the movable seat 1010. The driving end of the first driving mechanism 103 is connected to the support 1011 and is used to drive the support 1011 to move towards the direction of the chuck 31 to lift the chuck 31.
[0060] In this embodiment, the movable frame 101 is divided into two parts: a movable seat 1010 and a support platform 1011. The limiting groove 102 on the movable seat 1010 can be used to support the material cylinder 2, and the support platform 1011 can be used to support the chuck 31. When the first drive mechanism 103 drives the support platform 1011 to move towards the chuck 31 (e.g., upward), the limiting groove 102 can lift the material cylinder 2, and the support platform 1011 can lift the chuck 31, so that the limiting member 20 on the material cylinder 2 and the positioning member 32 on the chuck 31 are precisely aligned.
[0061] During feeding, after the positioning element 32 is aligned with the limiting element 20 of the material cylinder 2 by rotating the roller 11, the first drive mechanism 103 can drive the support platform 1011 to move towards the chuck 31 (e.g., upward), so that the limiting groove 102 lifts the material cylinder 2 and the support platform 1011 lifts the chuck 31, so that the limiting element 20 on the material cylinder 2 and the positioning element 32 on the chuck 31 are precisely aligned.
[0062] During unloading, the first drive mechanism 103 can drive the support platform 1011 to move away from the chuck 31 (e.g., downwards), which allows the limiting groove 102 to separate from the cylinder 2, the support platform 1011 to separate from the chuck 31, and the cylinder 2 to be pressed back onto the roller 11, thus supporting the cylinder 2 and facilitating the smooth separation of the chuck 31 from the cylinder 2. This enhances the safety of unloading and loading operations, reduces the rate of unwinding, and lowers cost losses.
[0063] As an optional embodiment, see Figure 5 The movable frame 30 can move along the axial direction of the material cylinder 2 so that the chuck 31 moves toward or away from the material cylinder 2.
[0064] In this embodiment, the movable frame 30 can be movably mounted on the frame 5 of the winding and unwinding equipment and moves along the axial direction of the drum 2 on the frame 5 so that the chuck 31 moves toward or away from the drum 2, adjusting the distance between the chuck 31 and the drum 2 so that the limiting member 20 on the drum 2 and the positioning member 32 on the chuck 31 are precisely aligned.
[0065] As a preferred embodiment, see Figure 5 The clamping mechanism 3 also includes a fourth drive mechanism 34, which is connected to the movable frame 30 and is used to drive the movable frame 30 to move along the axial direction of the material cylinder 2.
[0066] In this embodiment, the fourth driving mechanism 34 drives the moving frame 30 to move along the axial direction of the material cylinder 2, so that the chuck 31 moves toward or away from the material cylinder 2, so that the limiting member 20 on the material cylinder 2 and the positioning member 32 on the chuck 31 cooperate to limit the clamping of the material roll.
[0067] In this embodiment, the fourth drive mechanism 34 can be a servo motor, cylinder, etc., and this application does not limit it.
[0068] As a preferred embodiment, see Figure 5 The clamping mechanism 3 also includes a third drive mechanism 33, which is arranged along the axial direction of the material cylinder 2 through the moving frame 30 and is connected to the chuck 31 and is used to drive the chuck 31 to rotate.
[0069] In this embodiment, the third drive mechanism 33 passes through the movable frame 30 and only drives the chuck 31 to rotate, but does not drive the movable frame 30 to rotate.
[0070] In this embodiment, the third drive mechanism 33 can be a servo motor, cylinder, etc., and this application does not limit it.
[0071] As an optional embodiment, see Figure 1 One of the positioning element 32 and the limiting element 20 is a protrusion, and the other is a groove.
[0072] In this embodiment, the positioning member 32 can be a protrusion and the limiting member 20 can be a groove; or, the positioning member 32 can be a groove and the limiting member 20 can be a protrusion.
[0073] Taking the positioning element 32 as a protrusion and the limiting element 20 as a groove as an example, at least one end of the chuck 31 is provided with a protrusion facing the material cylinder 2. The protrusion can be arranged radially or circumferentially along the chuck 31. At least one end of the material cylinder 2 is provided with a groove facing the chuck 31. The groove can be arranged radially or circumferentially along the material cylinder 2.
[0074] When the barrel 2 rotates at a first preset angle, the groove can be set horizontally, and when the positioning member 32 rotates at a second preset angle, the protrusion can be set horizontally, so that the groove and the protrusion are set opposite to each other.
[0075] When the moving frame 30 moves along the axial direction of the material cylinder 2, the chuck 31 moves toward the material cylinder 2, so that the protrusion is inserted into the groove, thereby achieving the limiting clamping of the chuck 31 and the material cylinder 2.
[0076] Corresponding to the aforementioned application function implementation device embodiments, this application also provides a winding and unwinding device and corresponding embodiments.
[0077] See Figure 5 This application embodiment also provides a winding and unwinding device, including a frame 5 and at least two of the aforementioned clamping devices, the at least two clamping devices being arranged opposite to each other to form a clamping space for clamping the material cylinder 2.
[0078] In this embodiment, the frame 5 may include a horizontally arranged frame body and two side plates located at both ends of the frame body. Two sets of clamping devices may be provided, each set located on one side of the frame body. Each set of clamping devices may have two clamping devices positioned opposite each other at both ends of the frame body, forming a clamping space between the two oppositely positioned clamping devices to hold the material cylinder 2. During loading and unloading, the material roll can be loaded and unloaded through the clamping space.
[0079] During the feeding process, production personnel do not need to align the material cylinder 2 with the chuck 31 beforehand. The material cylinder 2, containing the material roll, can be directly placed on the roller 11 via an automatic guide trolley. Supported by the bracket 10, the roller 11 drives the material cylinder 2 to rotate by a first preset angle. After the material cylinder 2 stops rotating, the positioning component 32 rotates with the chuck 31 by a second preset angle. After the positioning component 32 stops rotating, it is aligned with the limiting component 20 of the material cylinder 2, allowing them to achieve a limiting engagement after moving closer together. This ensures accurate positioning of the material cylinder 2 and the chuck 31, improves the success rate of material roll feeding, enhances the stability and neatness of roll winding and unwinding, and ultimately guarantees the quality of the roll. Simultaneously, it also contributes to the automation of the winding and unwinding mechanism.
