Description

Technical Field

[0001] This utility model relates to the field of optical thin film processing technology, and in particular to an optical thin film punching and cutting device. Background Technology

[0002] In precision manufacturing fields such as optical displays and electronic devices, optical thin films are key components, and their processing precision directly affects the optical performance and usability of products. Optical thin film punching equipment, as the core equipment for achieving precise slitting and forming of thin films, can process wide thin films into narrow strips of specific widths or finished products of target shapes, meeting the diverse needs of different products for film size and shape.

[0003] In the prior art, equipment used for optical thin film processing typically consists of a separate slitting machine and a punching machine. The slitting machine uses blades in fixed positions to longitudinally cut the film, while the punching machine uses pressure to press the film into shape.

[0004] However, existing optical thin film processing equipment has a fixed slitting blade position, making it difficult to flexibly adjust the slitting width. Furthermore, the slitting and punching functions need to be completed by two separate machines. This not only makes the adjustments during production changeover cumbersome and time-consuming, but also results in low processing efficiency and reduced precision due to manual film transfer. As a result, it cannot meet the demand for efficient and precise processing of diverse specifications of films. Therefore, an optical thin film punching equipment is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an optical thin film punching device, which aims to improve the problems in the prior art where the slitting blade position is fixed and it is difficult to flexibly adjust the slitting width, and the slitting and punching functions need to be completed by two separate devices.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An optical thin film punching and cutting device includes a frame, a fixed frame fixedly connected to the top of the frame, a support frame fixedly connected to the top of the frame, cylinders fixedly connected to the top of both the fixed frame and the support frame, slides fixedly connected to the output ends of both cylinders, sliders fixedly connected to the side walls of both slides, a plurality of sliders slidably connected inside the fixed frame and the support frame, a sliding assembly disposed inside one slide, a punching blade fixedly connected inside the other slide, and a feeding assembly disposed on the top of the frame;

[0008] The slitting assembly includes a rotating column and multiple slitting blades. The rotating column is rotatably connected inside one of the slides, and the multiple slitting blades are slidably connected to the outer wall of the rotating column. A support block is fixedly connected to one side of one of the slides, and a second motor is fixedly connected to one side of the support block. One end of the rotating column is fixedly connected to the output end of the second motor, and an adjustment assembly is provided on one side of each of the multiple slitting blades.

[0009] As a further description of the above technical solution:

[0010] The feeding assembly includes two sets of fixed frames and feeding rollers. The two fixed frames are symmetrical from left to right and their bottoms are fixedly connected to the top of the frame. The two feeding rollers are rotatably connected inside the two fixed frames.

[0011] As a further description of the above technical solution:

[0012] Each of the two fixed frames is fixedly connected to one side of a motor, and one end of each of the two feeding rollers is fixedly connected to the output end of the two motors.

[0013] As a further description of the above technical solution:

[0014] The adjustment assembly includes multiple collars and positioning pins. One end of each collar is fixedly connected to one side of each of the multiple slitting blades. Each positioning pin is threadedly connected to the inside of each collar. All collars are slidably connected inside the rotating column.

[0015] As a further description of the above technical solution:

[0016] The rotating column has multiple positioning holes inside, and multiple positioning pins are respectively inserted into the corresponding positioning holes.

[0017] As a further description of the above technical solution:

[0018] A support frame is fixedly connected to the top of the frame, and symmetrical upper and lower limiting rods are rotatably connected inside the support frame.

[0019] As a further description of the above technical solution:

[0020] The support frame is rotatably connected to a bidirectional screw, one end of which is fixedly connected to a handwheel, and the outer wall of the bidirectional screw is threaded with symmetrical sliding blocks.

[0021] As a further description of the above technical solution:

[0022] Each of the two sliding blocks is fixedly connected to a limiting plate on one side, and both limiting plates are slidably connected to the outer walls of the two limiting rollers.

[0023] As a further description of the above technical solution:

[0024] A guide rod is fixedly connected inside the support frame, and a sliding sleeve is fixedly connected to the bottom of the sliding block. The sliding sleeve is slidably connected to the outer wall of the guide rod.

[0025] As a further description of the above technical solution:

[0027] This utility model has the following beneficial effects:

[0028] 1. In this utility model, by loosening the positioning pin on the collar, the collar is moved along the axis of the rotating column to drive the slitting blade to adjust the spacing. The positioning pin is aligned with the positioning hole and tightened. The second motor drives the rotating column to rotate the slitting blade to slit. In conjunction with the cylinder pushing the slide to drive the punching blade to move down to punch the film in the punching area, the slitting width can be flexibly adjusted and the slitting and punching can be performed simultaneously. This solves the problem that the slitting blade position is fixed and it is difficult to flexibly adjust the slitting width, and the slitting and punching functions need to be completed by two separate devices, thereby improving the practicality of the optical film punching equipment.

[0029] 2. In this utility model, the handwheel on the operating support frame drives the bidirectional screw to rotate. The bidirectional screw drives the sliding block to move relative to or away from each other. The limiting plate on the sliding block moves between the two limiting rollers, which realizes the effect of lateral limiting of films of different widths during feeding. This solves the problem that traditional equipment is difficult to adapt to the conveying of films of different widths and is prone to affecting the processing accuracy due to film offset, thereby improving the flexibility of optical film punching equipment.

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

[0038] Reference Figures 1-3 This utility model provides an embodiment of an optical thin film punching device, comprising a frame 1, a fixed frame 2 and a support frame 3 fixedly connected to the top of the frame 1, the fixed frame 2 and the support frame 3 being rigidly connected to the frame 1 by bolts, providing mounting support for actuators such as cylinders 7 and slides 8, cylinders 7 being fixedly connected to the top of both the fixed frame 2 and the support frame 3, and slides 8 being fixedly connected to the output ends of both cylinders 7, enabling smooth lifting and lowering under the drive of the cylinders 7, providing reliable up-and-down movement power for the slitting assembly and the punching blade 14, and both slides 8 having side walls A slider 9 is fixedly connected, and multiple sliders 9 are slidably connected inside the fixed frame 2 and the support frame 3 respectively. The slider 9 provides guidance for the lifting and lowering movement of the carriage 8, ensuring that the carriage 8 moves smoothly along the preset trajectory and avoiding deviation that affects the processing accuracy. One of the carriages 8 is equipped with a cutting component, which is responsible for cutting the wide film into the required narrow width. Another carriage 8 is fixedly connected with a punching knife 14, which is made of high-speed steel and precision ground. The cutting edge is sharp and wear-resistant and is used to form and punch the film. A feeding component is set on the top of the frame 1 to provide stable power and guidance for film conveying.

[0039] The slitting assembly includes a rotating column 12 and multiple slitting blades 13. The rotating column 12 is rotatably connected inside one of the slides 8, and the multiple slitting blades 13 are slidably connected to the outer wall of the rotating column 12. All slitting blades 13 are made of hard alloy, with highly wear-resistant blades, and can be moved axially to adjust their spacing. A support block 10 is fixedly connected to one side of one of the slides 9, and a second motor 11 is fixedly connected to one side of the support block 10. The second motor 11 is a servo motor, featuring adjustable speed and stable torque, which is existing technology and will not be described in detail here. The support block 10 is firmly connected to the slide 9 by bolts, providing mounting support for the second motor 11. One end of the rotating column 12 is fixedly connected to the output end of the second motor 11. When the second motor 11 is working... The drive column 12 rotates precisely, providing stable cutting power for the slitting blades 13. Each of the multiple slitting blades 13 has an adjustment component on one side, which includes multiple collars 15 and positioning pins 17. One end of each collar 15 is fixedly connected to one side of each slitting blade 13, and each positioning pin 17 is threaded into the collar 15. Each collar 15 is slidably connected to the inside of the drive column 12. The drive column 12 has multiple positioning holes 16, and each positioning pin 17 passes through the corresponding positioning hole 16. The collars 15 and the drive column 12 are rigidly locked by the threaded fastening force, ensuring that the position of the slitting blades 13 is fixed and preventing the spacing from shifting due to vibration during the slitting process, thus ensuring the consistency of the slitting width.

[0040] Reference Figures 2-4 The feeding assembly includes two sets of fixed frames 4 and feeding rollers 6. The two fixed frames 4 are symmetrical and fixedly connected to the top of the frame 1 at the bottom. The two feeding rollers 6 are rotatably connected inside the two fixed frames 4 and adopt a rubber-coated roller structure, which has good elasticity and friction. It can not only stably clamp the film to prevent slippage, but also avoid scratching the functional coating on the surface of the optical film. A motor 5 is fixedly connected to one side of each of the two fixed frames 4. One end of each of the two feeding rollers 6 is fixedly connected to the output end of the two motors 5. When the motors 5 are working, they drive the feeding rollers 6 to rotate synchronously. Through the friction between the motor and the film, the film is continuously and uniformly fed, ensuring the coordination of the processing rhythm and the slitting and punching actions.

[0041] Reference Figure 1 and Figure 5A support frame 18 is fixedly connected to the top of the frame 1 by bolts, providing installation support for components such as the limiting rollers 19 and the bidirectional screw 20. The support frame 18 contains symmetrically arranged limiting rollers 19, made of chrome-plated steel tubing, which provide initial guidance and limiting for the film, preventing significant deviation during initial transport. A bidirectional screw 20 is rotatably connected inside the support frame 18, with a handwheel 25 fixedly connected to one end for manual adjustment. Symmetrical sliding blocks 21 are threaded onto the outer wall of the bidirectional screw 20. Due to the opposite rotation directions at both ends of the bidirectional screw 20, rotation allows the sliding blocks 21 to move relative to or away from each other. Limit plates 22 are fixedly connected to one side of each sliding block 21, and both limit plates 22 are slidably connected to the outer walls of the two limiting rollers 19. 2. Made of wear-resistant plastic material, with a flexible rubber pad on the inside, it can move synchronously with the sliding block 21 to accurately limit the lateral movement of films of different widths, ensuring the stability of the film conveying path. The support frame 18 is fixedly connected to the guide rod 23, and the bottom of the sliding block 21 is fixedly connected to the sliding sleeve 24. The sliding sleeve 24 is slidably connected to the outer wall of the guide rod 23, which plays an auxiliary guiding role in the movement of the sliding block 21, preventing it from rotating or deviating during the movement, and ensuring the accuracy of the adjustment of the limit plate 22. The frame 1 has a material drop trough 26 inside, which facilitates the collection and falling of waste and debris generated during the cutting process. The bottom of the frame 1 is equipped with a collection box 27, which is located at the bottom of the fixed frame 2 and adopts a drawer-type structure, which can be easily pulled out for cleaning, avoiding the accumulation of waste and affecting the equipment operating environment, keeping the processing area clean, and reducing equipment maintenance costs.

[0042] Working principle: When using this optical film punching equipment, the operator first guides the optical film to be processed, passing one end of the film through the symmetrical upper and lower limiting rollers 19 in the support frame 18, and then through the feeding roller 6. Then, the motor 5 is started. The output end of the motor 5 drives the feeding roller 6 to rotate in the fixed frame 4. When the feeding roller 6 rotates, it continuously conveys the film to the slitting and punching area inside the equipment through the friction between the feeding roller 6 and the film. Before the film is conveyed to the slitting area, the spacing of the slitting blades 13 can be adjusted according to the processing requirements. First, loosen the positioning pin 17 on the collar 15, move the collar 15 along the axis of the rotating column 12, and drive the slitting blades 13 to move synchronously. After aligning the positioning pin 17 with the corresponding positioning hole 16 of the rotating column 12, tighten it to complete the setting of the spacing of the slitting blades 13. Then, the motor 11 is started, and its output end drives the rotating column 12 to rotate, so that the slitting blades 13 rotate with the rotating column 12 to slitting the conveyed film, cutting the wide film into the required narrow width.

[0043] When the film needs to be punched, the film continues to be conveyed to the punching area. At this time, the cylinder 7 is activated, and its output end pushes another slide 8 to move down. The punching blade 14 on the slide 8 moves down accordingly to punch the slit film and obtain the optical film product of the target shape. Waste and debris generated during the slitting process can fall into the collection box 27 below through the drop chute 26 opened at the top of the frame 1, which is convenient for regular centralized cleaning and keeping the processing area of ​​the equipment clean.

[0044] When processing films of different widths, the handwheel 25 on the support frame 18 can be operated to drive the bidirectional screw 20 to rotate. The sliding block 21, which is threaded to the outer wall of the bidirectional screw 20, can move relative to or away from each other due to the rotational characteristics of the bidirectional screw 20. The limiting plate 22 on the sliding block 21 moves between the two limiting rollers 19 accordingly, and the films of different widths are laterally limited on the feeding roller 6 to prevent the films from deviating during transportation. Thus, films of different widths can be effectively limited.
