[0018] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0019] like Figures 1 to 4 As shown, this utility model discloses a wire-wrapping masking tape rotation module, including a base 1. The front side of the base 1 is provided with a first clamping device 2 for clamping the main body of the wire. The base 1 is provided with a sliding seat 3 that can slide back and forth relative to the base 1. The sliding seat 3 is provided with a clamping and pressing assembly 4. The clamping and pressing assembly 4 includes a mandrel 41 fixedly connected to the sliding seat 3 and extending forward, a second clamping device 42 connected to the front end of the mandrel 41 and capable of clamping the end of the wire, a rotating sleeve 43 sleeved on the mandrel 41 and capable of rotating around it, and a pressing device 44 connected to the front end of the rotating sleeve 43 and used to press the masking tape. The sliding seat 3 is also provided with a first driving mechanism 5 that can drive the rotating sleeve 43 to rotate, thereby driving the pressing device 44 to wrap the masking tape around the wire.

[0020] The base 1 can be made of metal profiles or castings to ensure sufficient rigidity and stability. A first clamping device 2 is provided on the front side of the base 1 for clamping the main body of the wire. The first clamping device 2 fixes the middle position of the wire, ensuring overall stability of the wire during subsequent paper winding. The sliding seat 3 is preferably guided and slidable via a guide rail pair or linear bearing, allowing it to slide back and forth on the base 1. The sliding seat 3 enables the clamping and pressing assembly 4 to move forward to the wire, facilitating subsequent paper winding operations. The mandrel 41 is a forward-extending shaft structure, with its rear end fixedly connected to the sliding seat 3. In this embodiment, its central axis is aligned with the wire's extension direction, providing a reference axis for rotation. The mandrel 41 provides a mounting base for the second clamping device 42, the rotating sleeve 43, and the pressing device 44. The second clamping device 42 can clamp the end of the wire using pneumatic or electromagnetic clamps. The jaw sizes of the first clamping device 2 and the second clamping device 42 can be adjusted according to the wire diameter. The second clamping device 42 is connected to the front end of the mandrel 41, thereby clamping both ends of the wire together with the first clamping device 2 to ensure stability during the paper winding process. A rotating sleeve 43 is fitted around the mandrel 41 and can rotate relative to it. The pressing device 44 is connected to the front end of the rotating sleeve 43, and during its rotation driven by the drive mechanism 5, it adheres the masking tape to the wire. The drive mechanism 5 can be a stepper motor, servo motor, or other type connected to the rotating sleeve 43 via gears, synchronous belts, or couplings to transmit rotational power.

[0021] The first clamping device 2 is preferably in the form of a pneumatic or electric clamp. In the embodiment, the first clamping device 2 includes a clamping cylinder 21, and a first clamping jaw 22 and a second clamping jaw 23 connected to the clamping cylinder 21 and capable of being driven by the clamping cylinder 21 to perform clamping actions. The clamping cylinder 21 controls the opening and closing of the jaws to ensure the overall stability of the wire during the paper winding process.

[0022] In one embodiment, the working steps of the wire-wrapping-with-mask-paper rotation module are as follows: The wire is conveyed from the previous process to this module station. At this time, masking paper has been initially attached to the wire. After the fixture moves the wire to the set position, the first clamping device 2 starts clamping. Then, the sliding seat 3 moves forward, bringing the second clamping device 42 closer to the end of the wire. After reaching the set position, the second clamping device 42 starts clamping, clamping the end of the wire. The pressing device 44 starts and presses it onto the masking paper. Subsequently, the first drive mechanism 5 starts, driving the rotating sleeve 43 to rotate. The rotating sleeve 43 drives the pressing device 44 connected to its front end to rotate synchronously. During the rotation, the pressing device 44 continuously applies pressure, so that the masking paper is evenly wrapped and adhered to the surface of the wire end. After the action is completed, each actuator resets, releases the clamps, and prepares to enter the next cycle. This wire-wrapping-with-mask-paper rotation module can further wrap and adhere the masking paper that has been initially attached to the end of the wire to the wire, making it firmly adhered to the surface of the wire.

[0023] By installing the second clamping device 42 at the front end of the mandrel 41 and the pressing device 44 at the front side of the rotating sleeve 43 sleeved on the mandrel 41, the clamping and pressing assembly 4 has a compact structure. Compared with the traditional paper winding module with dispersed actuators, the paper winding module of this application is small in size and highly modular. It can adapt to the space-constrained compact automated production line environment and is easier to integrate with other equipment.

[0024] The second clamping device 42 includes a first clamping jaw 421 and a second clamping jaw 422 that can move up and down. The first clamping jaw 421 is provided with a first rack 4211, and the second clamping jaw 422 is provided with a second rack 4221. A central rotating shaft 423 is inserted inside the spindle 41. A transmission gear 424 is fixedly connected to the front end of the central rotating shaft 423. The transmission gear 424 meshes with the first rack 4211 and the second rack 4221, so that when the transmission gear 424 rotates, it can drive the first clamping jaw 421 and the second clamping jaw 422 to move closer or further apart. The sliding seat 3 is provided with a second driving mechanism 6 that can drive the central rotating shaft 423 to rotate.

[0025] In this embodiment, the first rack 4211 and the second rack 4221 are located on both sides of the central rotating shaft 423 and arranged parallel to it. The central rotating shaft 423 extends from front to back through the mandrel 41 and to the rear side of the sliding seat 3. A transmission gear 424 is fixedly connected to the front end of the central rotating shaft 423. The transmission gear 424 meshes with both the first rack 4211 and the second rack 4221, so that when the transmission gear 424 rotates, it can drive the two grippers to move inward or outward synchronously, thereby clamping or releasing the wire end. When the second drive mechanism 6 is activated, it can drive the central rotating shaft 423 to rotate, and through the central rotating shaft 423, drive the transmission gear 424 to rotate synchronously, thereby causing the first gripping gripper 421 and the second gripping gripper 422 to move in opposite directions. When the transmission gear rotates forward, the two grippers move towards the middle to achieve the clamping action; when it rotates backward, the grippers are released. By setting the second drive mechanism 6 on the sliding seat 3 and driving it through the central rotating shaft 423, the drive components are avoided from being arranged at the front end of the spindle 41, reducing the front end weight, improving the response speed of the clamping action, saving space, and improving the overall integration of the module.

[0026] In this embodiment, the sliding seat 3 includes a guide rail 32 disposed on the seat body 1 in the front-back direction, a sliding table 31 slidably connected to the guide rail 32, and a sliding table mounting plate 33 disposed on the sliding table 31 in the vertical direction. A spindle 41 is mounted on the front side of the sliding table mounting plate 33. The seat body 1 is also provided with a drive cylinder 34 capable of controlling the front-back movement of the sliding table 31, thereby causing the sliding table 31 and the sliding table mounting plate 33 disposed on the sliding table 31 to move back and forth, thereby driving the clamping and pressing assembly 4 to move closer to or away from the first clamping device 2. The movement of the sliding seat 3 can also be achieved by means of a servo motor and a lead screw.

[0027] The number of clamping and pressing components 4 is two, and the rear ends of the central rotating shafts 423 of the two clamping and pressing components 4 are fixedly connected to clamping arms 425. The second driving mechanism 6 includes a clamping cylinder 61 provided on the sliding seat 3. The clamping cylinder 61 has a piston rod 611. The end of the piston rod 611 is connected to the end of one of the clamping arms 425, and the piston rod 611 can drive the clamping arm 425 to rotate when it extends or retracts. A linkage mechanism 7 is provided between the two clamping arms 425, which can drive the other clamping arm 425 to rotate in the same direction when one of the clamping arms 425 rotates.

[0028] Two clamping and pressing components 4 are symmetrically arranged on the sliding seat 3, allowing them to simultaneously clamp both ends of the wire or process two independent wires separately, improving work efficiency. When the clamping cylinder 61 drives the piston rod 611 to extend or retract, it pushes or pulls the connected clamping arm 425 to rotate around the central axis 423. A linkage mechanism 7 is provided between the two clamping arms 425, with both ends of the linkage mechanism 7 connected to the free ends of the two clamping arms 425 respectively. This allows the other clamping arm 425 to rotate in the same direction when one clamping arm 425 is driven to rotate, thereby enabling the second clamping device 42 of the two clamping and pressing components 4 to open and close synchronously.

[0029] In this embodiment, the linkage mechanism 7 includes a connecting rod 71 connected to two clamping arms 425, and a spring seat 72 provided on the connecting rod 71. The spring seat 72 provides a certain preload to the linkage mechanism 7, so that it remains stable during movement, thereby improving the stability of the linkage mechanism 7.

[0030] The front part of the mandrel 41 is fixedly connected to a first mounting plate 45. A first linear guide rail 46 is provided on the left side of the first mounting plate 45 along the vertical direction, and a second linear guide rail 47 is provided on the right side of the first mounting plate 45 along the vertical direction. The first linear guide rail 46 and the second linear guide rail 47 are arranged parallel to each other. The first clamping jaw 421 is slidably connected to the first linear guide rail 46, and the second clamping jaw 422 is slidably connected to the second linear guide rail 47. The first rack 4211 and the second rack 4221 are arranged opposite to each other, and the transmission gear 424 is located between the first clamping jaw 421 and the second clamping jaw 422.

[0031] The front side of the rotating sleeve 43 is fixedly connected to a second mounting plate 48, and a third linear guide rail 49 is provided on the second mounting plate 48. The pressing device 44 includes a first pressing claw 441 and a second pressing claw 442 slidably connected to the third linear guide rail 49. A third driving mechanism 8 is provided between the first pressing claw 441 and the second pressing claw 442, which can drive the two to move closer or further apart.

[0032] The guide components are integrated on the first mounting plate 45 and the second mounting plate 48, featuring a high degree of modularity and facilitating disassembly and replacement. Linear guide rails guide the grippers up and down, ensuring a straight clamping path and uniform clamping force distribution.

[0033] In this embodiment, one or more guide rod bodies are provided between the first pressing claw 441 and the second pressing claw 442. A spring is sleeved on the guide rod body to further guide the movement direction of the claws and to cause the first pressing claw 441 and the second pressing claw 442 to quickly reset through the spring.

[0034] The third driving mechanism 8 includes a first pressing cylinder 81 and a second pressing cylinder 82 disposed on the second mounting plate 48. The output end of the first pressing cylinder 81 is connected to the first pressing claw 441, and the output end of the second pressing cylinder 82 is connected to the second pressing claw 442.

[0035] When the two cylinders operate synchronously, the first pressing jaw 441 and the second pressing jaw 442 move towards the center along the third linear guide rail 49, thereby clamping the masking tape; when operating in the opposite direction, the two jaws open, releasing the masking tape. The use of independent dual-cylinder drive facilitates precise control of the jaw opening and closing force and speed.

[0036] The clamping and pressing components 4 are in the form of two, and the first drive mechanism 5 is connected to a transmission mechanism 9 that enables it to synchronously drive all pressing devices 44 to rotate. The transmission mechanism 9 allows a single drive mechanism to complete multi-point synchronous rotation operations, simplifying the control system design. Simultaneously, the transmission mechanism 9 ensures that all pressing devices 44 rotate synchronously, guaranteeing uniform and consistent masking tape wrapping.

[0037] The first drive mechanism 5 includes a rotary motor 51 mounted on a sliding seat 3, and the transmission mechanism 9 includes a first synchronous pulley 91 connected to the output end of the rotary motor 51, a second synchronous pulley 92 mounted on each rotating sleeve 43, and a synchronous belt 93 connecting the first synchronous pulley 91 to all the second synchronous pulleys 92.

[0038] After the rotary motor 51 is started, the power is transmitted sequentially through the first synchronous pulley 91 and the synchronous belt 93 to each of the second synchronous pulleys 92, ultimately driving the rotating sleeves 43 in each clamping and pressing assembly 4 to rotate synchronously, thereby realizing the synchronous rotation of all pressing devices 44. Through the synchronous belt pulley system structure, the synchronous rotation operation of multiple clamping and pressing assemblies can be achieved by a single drive motor.
