[0022] This application discloses a punching device for a strip 10, comprising: 100 racks; The drive roller 200 is rotatably mounted on the frame 100 and is used to wind the material belt 10; The needle roller assembly 300 is provided in multiple ways. The drive roller 200 has opposite sides, and each side of the drive roller 200 is provided with at least one needle roller assembly 300. The needle roller assembly 300 includes a rotatably disposed roller body 310. The side surface of the roller body 310 is provided with needles. The roller body 310 cooperates with the drive roller 200 to clamp the material strip 10. The needles are used to press into the material strip 10 passing through the roller body 310 to form blind holes.

[0023] In the technical solution of this utility model, a needle roller assembly 300 is set up and the material strip 10 is formed by physical rolling, which avoids the problem of heat-affected zone caused by high temperature during laser drilling and avoids the formation of heat-affected zone. In addition, by cooperating with the roller body 310 and the drive roller 200 to clamp the material strip 10 and roll it, continuous drilling of the material strip 10 is realized. The relative position of the roller body 310 and the drive roller 200 is fixed, which also ensures the drilling accuracy and reduces the complexity of the equipment and maintenance costs.

[0024] like Figures 1 to 4The frame 100 refers to the basic structure supporting the entire device, which can be a welded steel structure or an aluminum alloy frame structure. The drive roller 200 is a component rotatably mounted on the frame 100. The drive roller 200 is cylindrical and arranged in a horizontal direction. The drive roller 200 is used to wind and convey the material belt 10. Specifically, the drive roller 200 can be mounted on the frame 100 through bearings. One end of the drive roller 200 can be equipped with a motor to drive its rotation, so as to realize the continuous and stable movement of the material belt 10. The needle roller assembly 300 is used to complete the punching operation. Multiple needle roller assemblies 300 can be set, and at least one needle roller assembly 300 is set on each of the opposite sides of the drive roller 200. Each needle roller assembly 300 can be directly fixed to the frame 100 by a bracket. Each needle roller assembly 300 includes a rotatable roller body 310. The roller body 310 is cylindrical and arranged parallel to the drive roller 200. The roller body 310 and the drive roller 200 can cooperate to clamp the material strip 10. When the drive roller 200 rotates, the material strip 10 moves and drives the roller body 310 to rotate synchronously. The surface of the roller body 310 is provided with protruding needles. The needles form an array on the surface of the roller body 310. During the movement of the material strip 10, the needles can press into the material strip 10 and form blind holes on the material strip 10, thereby completing the punching operation. Multiple needle roller assemblies 300 are arranged on opposite sides of the drive roller 200, which can punch the material strip 10 at the same time, improving production efficiency. The above solution replaces laser drilling with mechanical roller pressing, avoiding the generation of heat-affected zones and protecting the material strip 10. At the same time, the device does not require complex electronic components such as lasers and controllers, simplifying the system structure and reducing manufacturing costs. Moreover, the synchronous rotation of the drive roller 200 and the needle roller assembly 300 ensures the consistency of hole positions and guarantees the accuracy of drilling.

[0025] like Figure 3 The diagram illustrates one structural form of the needle roller assembly 300. In this embodiment, the needle roller assembly 300 further includes: a support frame 320, which is fixedly connected to the frame 100; a connecting frame 330, which is slidably connected to the support frame 320 to be close to or away from the drive roller 200, and a roller body 310 is rotatably mounted on the connecting frame 330; and a drive member 340, which is mounted on the support frame 320 and is drivably connected to the connecting frame 330.

[0026] The bracket is a component that provides support for other parts on the needle roller assembly 300. It can be fixedly connected to the frame 100 by welding or bolting to ensure the stability of the needle roller assembly 300 during the punching process. The connecting frame 330 can achieve translational movement relative to the bracket through a sliding connection such as a guide rail slider or linear bearing. Through translation, the connecting frame 330 can move closer to or away from the drive roller 200 radially. The roller body 310 is rotatably mounted on the connecting frame 330. The driving component 340 is a component that provides power for the movement of the connecting frame 330. It can be in the form of a cylinder, hydraulic cylinder, or electric push rod. Driven by the driving component 340, the roller body 310 can come into contact with or disengage from the material belt 10. During the processing, when the material strip 10 on the drive roller 200 needs to be punched, the drive unit 340 can push the roller body 310 to contact the material strip 10 to punch the hole. When the material strip 10 does not need to be punched or needs to be replaced, the drive unit 340 can drive the roller body 200 to detach from the material strip 10. In this way, the user can adjust the needle roller assembly 300 according to the needs, which improves the flexibility of use.

[0027] In another embodiment of this application, the roller body 310 and the connecting frame 330 are detachably connected. Specifically, the roller body 310 can be connected by means of threaded connection or other methods. When the needle body is worn or damaged, the roller body 310 can be quickly replaced without disassembling the entire needle roller assembly 300. In addition, users can also replace different roller bodies 310 according to the needs of different sizes or densities of punching, which facilitates the maintenance of the needle roller assembly 300 and expands the application scenarios of the punching device for the strip 10.

[0028] In another embodiment of this application, a mounting groove with a top opening is provided at one end of the connecting frame 330 near the drive roller 200, and limiting grooves with top openings are provided at both ends of the mounting groove. The roller body 310 includes two connecting parts 311 and a roller pressing part 312 rotatably disposed between the two connecting parts 311. The roller pressing part 312 is accommodated in the mounting groove, and the connecting parts 311 are embedded in the limiting groove.

[0029] The mounting groove is a groove with a top opening on the connecting frame 330 near one end of the drive roller 200. Its size and shape are adapted to the roller body 310 to provide a space for the roller body 310. Limiting grooves with top openings are provided at both ends of the mounting groove along the axial direction of the drive roller 200. In addition, the roller body 310 includes a rolling part 312 and a connecting part 311. The rolling part 312 is used to roll with the material belt 10. The needle body is provided on the outer surface of the rolling part 312. Support structures of the roller body 310, namely the connecting parts 311, are provided at both ends of the rolling part 312. The connecting parts 311 are rotatably connected to the rolling part 312. During installation, the roller body 310 allows the roller pressing part 312 to be directly inserted into the mounting groove from above, while the connecting part 311 is embedded in the limiting groove. The limiting groove constrains the axial and radial displacement of the connecting part 311, ensuring the stability of the roller pressing part 312's position. Furthermore, the limiting groove and the connecting part 311 can be fixed together with screws to further improve the stability of the roller body 310. When disassembling the roller body 310, simply lift the roller body 310 upwards; the roller pressing part 312 will detach from the mounting groove, and the connecting part 311 will detach from the limiting groove. Through this solution, this application ensures the installation accuracy of the roller body 310 while facilitating its disassembly, shortening replacement time, and improving maintenance efficiency, enabling the material strip 10 perforation device to better adapt to the demands of high-speed continuous production.

[0030] like Figure 3 In another embodiment of this application, the needle roller assembly 300 further includes a locking member 350, which connects the support frame 320 and the connecting frame 330 to fix or release the connecting frame 330. The locking member 350 can be a pin, snap-fit, or bolt. After the driving member 340 drives the roller 200 to abut or disengage from the driving roller 200, the locking member 350 can lock the connecting frame 330 to the support frame 320, thus eliminating the influence of equipment vibration or the traction force of the material belt 10 on the connecting frame 330 and keeping the position of the roller body 310 constant. When the roller body 310 is in contact with the material belt 10, the locking member 350 can prevent the position of the roller body 310 from shifting during the punching process of the material belt 10, improving punching accuracy and product consistency. When the roller body 310 is separated from the material belt 10, the locking member 350 can prevent the roller body 310 from contacting the material belt 10, preventing scraping between the material belt 10 and the roller body 310.

[0031] like Figure 4In another embodiment of this application, the locking member 350 includes: a support portion 351, fixedly connected to the support frame 320; a clamping portion 352, fixedly connected to the connecting frame 330, the clamping portion 352 having a first inclined surface inclined toward the support portion 351; a sliding portion 353, slidably disposed on the support portion 351 along a first direction, the sliding portion 353 having a second inclined surface adapted to the first inclined surface; and a driving portion 354, movably disposed on the support portion 351, the driving portion 354 being drively connected to the sliding portion 353 to drive the sliding portion 353 to abut or disengage from the clamping portion 352.

[0032] The support part 351 is a column and can be fixed to the support frame 320 with screws. The clamping part 352 is a square block structure and is fixed to the connecting frame 330 with screws. In addition, a slide rail can be provided on the side of the support part 351 facing the clamping part 352, and the sliding part 353 can be slidably connected to the slide rail. Figure 4 The sliding part 353 slides vertically. Additionally, a first inclined surface is provided on the side of the clamping part 352 facing the sliding part 353, and this first inclined surface slopes towards the support part 351, creating a wedge-shaped space between the clamping part 352 and the support part 351. Furthermore, a second inclined surface is provided on the side of the sliding part 353 facing the clamping part 352, and the second inclined surface slopes in the same direction as the first inclined surface. Additionally, the support part 351 is also provided with a driving part 354, which can be an electric push rod, cylinder, etc., and can drive the sliding part 353 along... Figure 4 It slides in the up and down direction. When the drive unit 340 drives the roller body 310 to contact the material belt 10, the clamping part 352 moves close to the support part 351, and then the drive unit 354 drives the sliding part 353 along the up and down direction. Figure 4 The sliding part 353 moves downwards, causing the first inclined surface to abut against the second inclined surface. At this time, the sliding part 353 can act like a wedge. The sliding part 353 applies a force away from the support part 351 to the clamping part 352. With the cooperation of the sliding part 353 and the driving member 340, the connecting frame 330 is clamped and fixed, ensuring the stability of the position of the roller body 310 during the punching process, thereby ensuring the punching quality. Similarly, when the driving member 340 drives the roller body 310 to separate from the material belt 10, the clamping part 352 moves away from the support part 351. Then, the driving part 354 drives the sliding part 353 to move its position and clamp it between the support part 351 and the clamping part 352. With the cooperation of the sliding part 353 and the driving member 340, the connecting frame 330 can also be clamped and fixed, preventing the roller body 310 from accidentally moving and contacting the material belt 10, thus reducing the risk of damage to the material belt 10.

[0033] like Figure 4As shown, in one embodiment of this application, the driving part 354 includes: a driving rod 3541, which is rotatably disposed on the support part 351 and threadedly engaged with the sliding part 353; and a locking member 3542, which is disposed on the support part 351 and is used to clamp or release the driving rod 3541.

[0034] The drive rod 3541 can be a screw, and the drive rod 3541 moves along... Figure 4 The drive rod 3541 extends vertically and is rotatably connected to the support 351. In addition, the bottom end of the drive rod 3541 passes through the sliding part 353 and is threadedly engaged with the sliding part 353. When the drive rod 3541 rotates, the drive rod 3541 can drive the sliding part 353 to move vertically. By using the above-mentioned threaded engagement, the position of the sliding part 353 can be finely adjusted, and by utilizing the self-locking characteristic of the thread, the stability of the sliding part 353 after it is adjusted to the correct position can be ensured. In addition, to further improve the stability of the fixed position of the sliding part 353, the support part 351 is also provided with a locking member 3542. The locking member 3542 includes a clamping block with an opening in the middle and a notch on one side. The drive rod 3541 can be inserted into the clamping block. The locking member 3542 also includes a screw. The screw is arranged laterally and connects the side walls on both sides of the notch. When the screw is rotated, it can drive the side walls on both sides of the notch to move closer or separate, thereby locking or releasing the drive rod 3541. When the drive rod 3541 adjusts the sliding part 353 into place, the locking member 3542 can be adjusted to lock the drive rod 3541. This can prevent the drive rod 3541 from rotating unexpectedly in a vibration environment and ensure that the needle roller assembly 300 maintains positioning stability during the punching process.

[0035] In another embodiment of this application, multiple needle roller assemblies 300 are staggered along the axial direction of the drive roller 200. Two needle roller assemblies 300 may be provided on each side of the drive roller 200, and each needle roller assembly 300 is staggered along the axial direction of the drive roller 200. This allows for simultaneous punching of the strip 10 at different positions along the axial direction of the drive roller 200, improving punching efficiency. Furthermore, the multiple needle roller assemblies 300 abutting against different positions on the drive roller 200 ensures uniform force distribution on the strip 10, thereby ensuring smooth operation of the strip 10 and high punching accuracy.

[0036] like Figure 1 In another embodiment of this application, the punching device for the strip 10 further includes: A vision inspection component 400 is disposed above each needle roller assembly 300. The vision inspection component 400 is used to detect the state of blind holes on the material strip 10. An ultrasonic dust removal component 500 is disposed below each needle roller assembly 300. The ultrasonic dust removal component 500 is used to emit ultrasonic waves toward one side of the conveyor belt 10 and remove dust from the conveyor belt 10.

[0037] The visual inspection component 400 is used to capture images of blind holes in the material strip 10. It can be implemented using an industrial camera and image processing algorithms to accurately identify blind hole positional deviations, abnormal hole diameters, or missing holes. The visual inspection component 400 is positioned above the needle roller assembly 300 to ensure that images of the blind holes are acquired after the needle body is pressed into the material strip 10, thereby judging the drilling quality and facilitating user adjustment of equipment parameters. The ultrasonic dust removal component 500 is a device that uses ultrasonic vibration to loosen and remove dust. It can be implemented using a combination of an ultrasonic generator and a negative pressure dust collection system. The ultrasonic dust removal component 500 is positioned below the needle roller assembly 300. It emits ultrasonic waves to detach dust particles adhering to the surface of the material strip 10 and generates a negative pressure airflow to suck the dust particles away from the material strip 10, thus improving the cleanliness of the material strip 10 and ensuring the normal operation of subsequent processes.

[0038] like Figure 1 In another embodiment of this application, the punching device for the strip 10 further includes a tension roller 600, which is disposed below the drive roller 200. The tension roller 600 cooperates with the drive roller 200 to clamp the strip 10. The tension roller 600 is arranged parallel to the drive roller 200. When the drive roller 200 rotates, the tension roller 600 rotates synchronously. Through their cooperation, the strip 10 maintains uniform tension during movement, thereby ensuring that the strip 10 remains straight in the punching area, improving overall punching quality and production continuity.

[0039] The above are merely exemplary embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the technical concept of this utility model and the contents of this utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
