Description

Technical Field

[0001] This utility model belongs to the field of laser film peeling technology, specifically a high-precision positioning integrated laser film peeling mechanism. Background Technology

[0002] In the processing of laser film, the peeling process requires first fixing the rolled laser film tube, and then peeling the laser film from the backing paper.

[0003] The existing integrated film tube fixing structure has poor adaptability. It can usually only fix film tubes with a single inner diameter. When changing film tubes of different specifications, it is necessary to disassemble and replace the corresponding clamps, which is cumbersome and inefficient. During the peeling process, the film tension fluctuates greatly, which can easily cause the material to wrinkle, stretch and deform or deviate, resulting in poor positioning accuracy and affecting the quality of subsequent laser processing or bonding. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the prior art, this utility model provides a high-precision positioning integrated laser film peeling mechanism, which effectively solves the problems mentioned in the background.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-precision positioning integrated laser film peeling mechanism, comprising a base body, a motor fixedly connected to one side of the base body, the output end of the motor extending through to one side of the base body and fixedly connected to a winding rod, a sensor provided on one side of the base body, and a limit mechanism and an adjustment mechanism respectively provided on one side of the base body;

[0006] The limiting mechanism includes a support base rotatably connected to one side of the machine base body. A housing is fixedly connected to one side of the support base. A transmission rod is rotatably connected to the inner wall of the support base. One end of the transmission rod extends through into the housing and is rotatably connected to the inner wall of the housing. A worm gear and a first bevel gear are fixedly sleeved on the outside of the transmission rod. A worm adapted to the worm gear is rotatably connected inside the support base. A handwheel is fixedly connected to the top of the worm and extends through to the top of the support base.

[0007] Preferably, the housing has four rectangular holes arranged in a ring array on one side, and four support plates arranged in a ring array are fixedly installed inside the housing. Four first lead screws arranged in a ring array are rotatably connected inside the housing. One end of the first lead screw passes through the extended support plate and is fixedly connected to a second bevel gear. The second bevel gear meshes with the first bevel gear. A movable plate is threaded to the outside of the first lead screw. The movable plate is slidably disposed in the rectangular holes. A limit rod is slidably disposed inside the movable plate. One end of the limit rod is fixedly connected to the inner wall of the housing, and the other end of the limit rod is fixedly connected to the support plate.

[0008] Preferably, a rectangular groove is provided on one side of the movable plate, an L-shaped block is provided in the rectangular groove, a positioning bolt is provided on one side of the movable plate, one end of the positioning bolt moves the plate and the L-shaped block, an arc plate is fixedly connected to one side of the L-shaped block, and a rubber pad is fixedly connected to one side of the arc plate.

[0009] Preferably, the adjustment mechanism includes a U-shaped frame fixedly installed on one side of the machine base body. A transmission roller is rotatably connected inside the U-shaped frame. An annular plate is fixedly sleeved on the outside of the transmission roller. A limiting plate is movably sleeved on the side of the transmission roller away from the annular plate. Sliding holes are opened on both sides of the U-shaped frame. A second lead screw is rotatably connected to the inner wall of the two sliding holes.

A vertical rod is fixedly connected to the upper part of one of the wheels.

[0010] Preferably, both of the second lead screws are threaded to the outside of a sliding plate, and the same tension roller is fixedly connected to the corresponding side of the two sliding plates.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model drives the worm gear to rotate by rotating the handwheel. The worm gear meshes with the worm wheel, which drives the transmission rod and the first bevel gear to rotate synchronously. The first bevel gear meshes with four second bevel gears, driving the four first lead screws to rotate. Under the guidance of the limiting rod, the moving plate moves radially along the rectangular hole, so that the arc plate limits the laser film cylinder. By rotating the positioning bolt and removing it, and then moving the L-shaped block, the arc plate can be disassembled and replaced. It can quickly and firmly fix film cylinders with various inner diameters, greatly reducing material change time and tooling costs.

[0013] 2. This utility model drives one of the rotating wheels to rotate by rotating the vertical rod. The two rotating wheels rotate synchronously through belt transmission, which in turn drives the second lead screw to rotate synchronously. The slide plate moves along the sliding hole, driving the tension roller to rise and fall, changing the relative height between the tension roller and the transmission roller. At the same time, the sliding limit plate moves along the axial direction of the transmission roller, forming a lateral constraint with the annular plate. This can limit the large deviation during material transmission, realize the active limiting and adjustment of tension, and ensure that the film is flat and vibration-free during the peeling process, providing a foundation for high-precision positioning processing.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Example 1, by Figures 1-4The present invention includes a base body 1, a motor 2 fixedly connected to one side of the base body 1, and a winding rod 3 fixedly connected to the output end of the motor 2 through one side of the base body 1. The winding rod 3 is directly used to wind the bottom paper to be wound. Driven by the motor 2, the rod rotates to evenly wind the bottom paper onto the rod, completing the winding operation. A sensor 4 is provided on one side of the base body 1. A limit mechanism 5 and an adjustment mechanism 6 are respectively provided on one side of the base body 1. The limit mechanism 5 includes a support base 501 rotatably connected to one side of the base body 1. The support base 501 is a frame structure and is rotatably connected to one side of the base body 1 through a bearing. A housing 502 is fixedly connected to one side of the support base 501. The housing 502 is a hollow cylinder and is fixed to the support base 501. On one side of the support base 501, a transmission rod 503 is rotatably connected to the inner wall of the support base 501. This transmission rod, acting as an intermediate transmission component, transmits the power of the worm gear 505 to the first bevel gear 507. One end of the transmission rod 503 extends through into the housing 502 and is rotatably connected to the inner wall of the housing 502. A worm wheel 504 and the first bevel gear 507 are fixedly sleeved on the outside of the transmission rod 503. A worm gear 505, compatible with the worm wheel 504, is rotatably connected inside the support base 501. A handwheel 506 extends through the top of the worm gear 505 to the top of the support base 501 and is fixedly connected to it. Rotating the handwheel 506 drives the worm gear 505 to rotate, thereby driving the worm wheel 504 and the transmission rod 503 to rotate slowly. Four openings are provided on one side of the housing 502. A rectangular hole 508 is arranged in a ring array. Four support plates 509 arranged in a ring array are fixedly installed inside the housing 502. Four first lead screws 510 arranged in a ring array are rotatably connected inside the housing 502. One end of each first lead screw 510 extends through the support plate 509 and is fixedly connected to a second bevel gear 511. The second bevel gear 511 meshes with the first bevel gear 507, converting the horizontal rotational motion of the transmission rod 503 into the radial rotational motion of the first lead screw 510. A movable plate 513 is threaded onto the outside of the first lead screw 510. The movable plate 513 is slidably disposed within the rectangular hole 508, which provides a channel for the movement of the movable plate 513. The movable plate 513 has limited internal sliding space. Positioning rod 512, one end of which is fixedly connected to the inner wall of housing 502, and the other end of which is fixedly connected to support plate 509. A rectangular groove 514 is provided on one side of moving plate 513, and an L-shaped block 515 is provided in the rectangular groove 514. A positioning bolt 516 is provided on one side of moving plate 513. One end of positioning bolt 516 moves plate 513 and L-shaped block 515. By rotating and removing positioning bolt 516, L-shaped block 515 can slide along rectangular groove 514 and be removed. An arc plate 517 is fixedly connected to one side of L-shaped block 515, and a rubber pad 518 is fixedly connected to one side of arc plate 517. The rubber pad 518 can increase the friction with the material and further improve the limiting stability.

[0023] The adjusting mechanism 6 includes a U-shaped frame 601 fixedly installed on one side of the machine base 1. A transmission roller 602 is rotatably connected inside the U-shaped frame 601. An annular plate 603 is fixedly sleeved on the outside of the transmission roller 602. A limiting plate 604 is movably sleeved on the side of the transmission roller 602 away from the annular plate 603. The transmission roller 602 guides the material to pass through its surface, reducing frictional resistance during material transmission. The annular plate 603 forms a lateral limiting on the transmission roller 602 to prevent the material from shifting axially along the roller body during transmission. Sliding holes 605 are provided on both sides of the U-shaped frame 601. The sliding holes 605 provide guidance for the movement of the slide plate 606, ensuring that the slide plate 606 only moves up and down in the vertical direction. The inner walls of the two sliding holes 605 are rotatably connected to a second... Two lead screws 607 extend through the top of the second lead screw 607 to the top of the U-shaped frame 601 and are fixedly connected to a wheel 609. The two wheels 609 are externally connected to the same belt 610. A vertical rod 611 is fixedly connected above one of the wheels 609. Slide plates 606 are threadedly connected to the outside of both second lead screws 607. The same tension roller 608 is fixedly connected to the corresponding side of the two slide plates 606. Rotating the vertical rod 611 drives one of the wheels 609 to rotate, and drives the other wheel 609 to rotate synchronously through the belt 610, thereby causing the two second lead screws 607 to rotate synchronously. Under the action of the threads, the slide plates 606 on both sides rise and fall synchronously along the sliding hole 605 to ensure that the tension roller 608 moves horizontally.

[0024] Working principle: In use, the laser film tube is sleeved over the arc plate 517. Turning the handwheel 506 drives the worm gear 505 to rotate. The worm gear 505 meshes with the worm wheel 504, driving the transmission rod 503 and the first bevel gear 507 to rotate synchronously. The first bevel gear 507 meshes with four second bevel gears 511, driving the four first lead screws 510 to rotate. Under the guidance of the limiting rod 512, the moving plate 513 moves radially along the rectangular hole 508, limiting the arc plate 517 on the laser film tube. Then, the laser film passes sequentially through the transmission roller 602 and tension roller 608 and winds onto the winding rod 3. The rotation of the motor 2 drives the winding rod 3 to wind up, separating the laser film from the backing paper. The separated laser film blocks the sensor 4, allowing... Sensor 4 can automatically sense and control the start and stop of motor 2. Workers can remove the laser film in sequence by rotating the positioning bolt 516 and then moving the L-shaped block 515 to disassemble and replace the arc plate 517. By rotating the vertical rod 611, one of the rotating wheels 609 is driven to rotate. The belt 610 drives the two rotating wheels 609 to rotate synchronously, which in turn drives the second lead screw 607 to rotate synchronously. The slide plate 606 moves along the sliding hole 605, which drives the tension roller 608 to rise and fall, changing the relative height between the tension roller 608 and the transmission roller 602 to adjust the tension. At the same time, the sliding limit plate 604 moves axially along the transmission roller 602, forming a lateral constraint with the annular plate 603, which can limit the large deviation during material transmission.
