Description

Technical Field

[0001] The present invention relates to the technical field of optical film cutting, and particularly relates to a three-axis positioning cutting device for optical films based on CCD vision detection. Background Art

[0002] Optical films are thin film materials with specific optical properties and are usually used in various optical and electronic applications. Optical thin films are prepared using materials with good optical transparency such as polycarbonate, polymethyl methacrylate, and polyester through processes such as extrusion, stretching, or coating, and then are cut and subjected to subsequent processing according to specific requirements.

[0003] Existing cutting devices for optical thin films, such as the optical film cutting device and method for a backlight module disclosed in Chinese document CN202211369287.6, although through the coordinated use of a control mechanism and a collection mechanism, reduce offset or quickly occur film offset and push the unevenly stacked films that fall into the inner side of the collection box to be neatly arranged, when the optical film is cut by the rectangular cutting device in this patent, the cut optical film or debris may stick to the cutting tool, which may lead to uneven cutting edges or damage, affecting the cutting quality, and it is necessary to stop the machine for cleaning or replace the cutting tool, significantly increasing the downtime of the production line and reducing the production efficiency. In addition, as the complexity of the film increases, the cutting tool also needs to be changed to a more complex cutting tool. These complexities not only require higher precision in cutting positioning but also higher precision requirements, and more and more miscellaneous scraps are generated during cutting and are more likely to adhere to the cutting tool. In view of this, the present invention proposes a three-axis positioning cutting device for optical films based on CCD vision detection to solve the problem that the cut optical film or debris may stick to the cutting tool. Summary of the Invention

[0007] Furthermore, the air blowing component further includes a heightening seat fixedly connected to the top surface of the upper knife holder. At least two heightening seats are fixedly connected to each side of the top surface of the upper knife holder. A transmission gear is rotatably connected to the heightening seat.

[0008] Furthermore, the anti-offset component includes a moving rod slidably connected to the four corners of the upper knife holder.

[0013] Further, at least two CCD cameras for positioning are fixedly connected inside the mounting frame, and a light-emitting strip for providing light sources to the CCD cameras is installed on the top surface of the workbench.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The present invention combines a CCD vision detection system with a control of a three-axis positioning cutting device. Based on the detection settings of the CCD vision detection system for ink dots, no matter how complex the cutting structure is, it can accurately position and control the three-axis positioning cutting device to achieve the operation of complex cutting structures. At the same time, the more complex the cutting is, the more scraps will be generated, and the cleaning requirements for the cutting tool are higher. Therefore, components such as a blowing component and an anti-offset component are provided. Through the linkage of the blowing component and the anti-offset component, the sealing cylinder inhales air, conveys the air to the high-pressure nozzle, and finally the high-pressure nozzle sprays out the air. And when spraying out, through a series of transmissions, the high-pressure nozzle moves and rotates. In this way, not only the cleaning of the cutting tool is realized, ensuring the cleanliness of the surface of the cutting tool, preventing the surface of the cutting tool from adhering to optical films or debris, which may lead to a decline in cutting quality or damage to the tool performance, but also the movement and rotation of the high-pressure nozzle enable the sprayed gas to cover the entire working surface of the cutting tool, improving the cutting accuracy and the yield rate.

[0016] 2. The present invention is provided with components such as a lower knife seat, a push plate, and a steel wire rope. When the upper knife seat and the lower knife seat approach each other, the push plate sinks into the groove of the lower knife seat, making the push plate in a horizontal position and cooperating with the cutting tool to complete the cutting work. When the upper knife seat and the lower knife seat move away from each other, one end of the push plate is connected to the workbench through a steel wire rope, and the other end is rotatably connected to the lower knife seat. Therefore, when the lower knife seat moves downward, an inclination angle will be formed, and thus the cut optical film will slide onto the conveyor belt. In this way, the optical film can be collected and moved quickly and smoothly without manual intervention, improving the production efficiency and the convenience of operation.

Detailed implementation manners

[0029] The present invention will be specifically introduced below in conjunction with the accompanying drawings and specific embodiments.

[0030] An optical film three-axis positioning and cutting device based on CCD vision detection, as Figures 1 - 11 shown, includes a workbench 1, a mounting frame 2 and an adjustment component 3. A mounting frame 2 is installed on the top surface of the workbench 1. Plate members 201 capable of blocking light sources are fixedly installed around the mounting frame 2. The materials used for the plate members 201 include, but are not limited to, black semi-transparent glass or aluminum alloy. Two CCD cameras 302 for positioning are fixedly connected inside the mounting frame 2. The CCD cameras 302 are used to capture the ink dots 901 on the optical film raw material 9. A light-emitting strip 303 for providing light sources to the CCD cameras 302 is installed on the top surface of the workbench 1. The black plate members 201 not only provide light source occlusion but also help reduce the influence of stray light from the surrounding environment, ensuring that the influence of the light in the working environment on the detection structure is minimized. The light-emitting strip 303 provides a constant and uniform light source that can irradiate the optical film raw material 9, making the ink dots 901 on the optical film raw material 9 clearer, improving the image quality captured by the CCD cameras 302, and enhancing the accuracy and reliability of vision detection. A mounting frame 2 is installed on the top surface of the workbench 1. An adjustment component 3 is arranged inside the mounting frame 2. The lower part of the adjustment component 3 is connected to a cutting component 4 for cutting the optical film raw material 9.

[0031] The adjustment assembly 3 includes a movable plate 301. An X-axis adjustment device 311 is installed on the top surface of the movable plate 301. A Y-axis adjustment device 312 is installed on the top surface of the X-axis adjustment device 311. An angle adjustment device 313 is installed on the top surface of the Y-axis adjustment device 312. A cutting assembly 4 is fixedly connected to the bottom of the angle adjustment device 313. Among them, the X-axis adjustment device 311 and the Y-axis adjustment device 312 are both prior arts, so they will not be elaborated here. In this embodiment, the angle adjustment device 313 includes components such as a connecting plate 3131, a movable shaft 3132, and a second moving block 3133. Two fixed seats 3134 are symmetrically and fixedly connected to the top surface of the Y-axis adjustment device 312. A second screw 3137 is rotatably connected between the two fixed seats 3134. A servo motor 3135 is fixedly installed on the side surface of one of the fixed seats 3134. The output shaft of the servo motor 3135 is fixedly connected to the second screw 3137. A sliding device 3136 is fixedly installed on the top surface of the Y-axis adjustment device 312. A second moving block 3133 is fixedly connected to the sliding device 3136. The second moving block 3133 is threadedly connected to the second screw 3137. A connecting plate 3131 is arranged between the second moving block 3133 and the cutting assembly 4. One end of the connecting plate 3131 is fixedly connected to the cutting assembly 4, and the other end is fixedly connected to a movable shaft 3132. The second moving block 3133 is provided with a groove for the movement of the movable shaft 3132. Specifically, when angle adjustment is required during work, the servo motor 3135 is started. The output shaft of the servo motor 3135 drives the second screw 3137 to rotate, thereby driving the second moving block 3133 to move. Then, the second moving block 3133 presses the movable shaft 3132, causing the movable shaft 3132 to move in the groove of the second moving block 3133, thereby causing the connecting plate 3131 to rotate, and then driving the upper half of the cutting assembly 4 to rotate, thus completing the angle adjustment. The adjustment assembly 3 is connected to the cutting assembly 4. A conveyor belt 5 for conveying the cut optical film is connected to the right part of the cutting assembly 4. An anti-offset assembly 7 for preventing the optical film raw material 9 from offsetting during cutting and a blowing assembly 6 for preventing the cut optical film from sticking to the cutting assembly 4 are arranged on the cutting assembly 4. The anti-offset assembly 7 and the blowing assembly 6 are connected to each other.

[0032] Furthermore, a feed inlet and a discharge outlet are provided on the left and right sides of the mounting bracket 2. Tensioning devices for tensioning the raw material 9 of the optical film are installed on the sides of the workbench 1 and the mounting bracket 2. The tensioning devices are the same as those in the prior art, so they will not be elaborated here. A waste winding assembly 8 is provided on the right side of the mounting bracket 2. The waste winding assembly 8 includes two mounting blocks 801 symmetrically fixed on the right side of the mounting bracket 2. A winding drum 802 is rotatably connected between the two mounting blocks 801. A second motor 803 is fixedly installed on the side of the mounting block 801. The output shaft of the second motor 803 is fixedly connected to the winding drum 802. During specific operation, the raw material 9 of the optical film has been coated with ink dots 901 and boundary lines 902 and has been cured in the previous process, as Figure 11 shown. Then, the raw material 9 of the optical film is wound around the tensioning device on the left, enters through the feed inlet of the mounting bracket 2, exits through the discharge outlet, and then is wound around the tensioning device on the right and finally fixed on the winding drum 802. When in use, the second motor 803 is started. The output shaft of the second motor 803 drives the winding drum 802 to wind, so that the raw material 9 of the optical film moves from left to right. While moving, the CCD camera 302 is started. The CCD camera 302 can detect the ink dots 901 on the raw material 9 of the optical film. When an ink dot 901 is detected, the second motor 803 is turned off, and thus the raw material 9 of the optical film stops being conveyed. Then, the CCD camera 302 transmits the image information of the ink dot 901 to the control system through an electrical signal. Then, the control system determines the position of the ink dot 901 in the image through algorithms such as feature point detection, calculates the deviation of the ink dot 901 relative to the tool origin based on the image information, and then starts the X-axis adjustment device 311, Y-axis adjustment device 312, and angle adjustment device 313 for adjustment according to this deviation, so as to achieve precise control and adjustment of the production process, effectively reduce errors and material losses in production, and improve production efficiency and resource utilization rate. Here, the CCD camera can perform precise identification and adjustment according to the radius of the ink dot to cope with the interference caused by a complex cutting structure with a large number of points, resulting in mispositioning. That is, only when the radius of the ink dot detected by the CCD meets the radius requirement is it determined that the ink dot is a cutting positioning ink dot, and then the electrical signal is transmitted to the control system. The condition for the radius of the ink dot to meet the radius judgment is implemented by conditional judgment codes in the CCD detection system, which will not be elaborated here.

[0033] Further, the cutting component 4 includes an upper tool holder 401 fixedly installed at the lower part of the connecting plate 3131. A cutting tool 402 is fixedly connected to the bottom surface of the upper tool holder 401. The air blowing component 6 includes a sealing cylinder 602 fixedly installed on the top surface of the upper tool holder 401. Two sealing cylinders 602 are installed on each side of the top surface of the upper tool holder 401. A movable rod 6021 is slidably connected in the sealing cylinder 602. A piston 6022 is fixedly connected to the lower part of the movable rod 6021. The piston 6022 is in sealed sliding connection with the sealing cylinder 602. A fixed rod 601 is fixedly connected to the upper part of the movable rod 6021. The fixed rod 601 is connected to the anti-offset component 7. The sealing cylinders 602 are connected to each other through pipes and one-way intake valves. Two groups of fixing blocks 604 are fixedly connected to each side of the bottom surface of the upper tool holder 401. Each group of fixing blocks 604 has two fixing blocks 604. A first screw rod 605 is rotatably connected between the two fixing blocks 604. A first moving block 603 is sleeved on the first screw rod 605 in a threaded manner. A high-pressure nozzle 606 is communicated with the bottom surface of the first moving block 603. The first moving block 603 is connected to the sealing cylinder 602 through a hose.

[0034] Further, the air blowing component 6 further includes a heightening seat 617 fixedly connected to the top surface of the upper tool holder 401. Two heightening seats 617 are fixedly connected to each side of the top surface of the upper tool holder 401. A transmission gear 616 is rotatably connected to the heightening seat 617. The transmission gear 616 is connected to the anti-offset component 7. An incomplete gear 611 is rotatably connected to the bottom surface of the first moving block 603. The incomplete gear 611 is fixedly connected to the high-pressure nozzle 606. Two meshing racks 612 are fixedly connected to each of the four side walls of the cutting tool 402. The meshing racks 612 are meshed with the incomplete gear 611. A first bevel gear 613 is fixedly connected to one end of the first screw rod 605. At least two second bevel gears 614 are rotatably connected to each of the four side walls of the cutting tool 402. The first bevel gear 613 is meshed with the second bevel gear 614. The second bevel gear 614 and the transmission gear 616 are connected to each other through a first synchronous belt assembly 615.

[0035] Further, the anti-offset component 7 includes a moving rod 701 slidably connected to the four corners of the upper tool holder 401. An elastic member 702 is arranged at the lower part of the moving rod 701. The elastic member 702 is a spring. The two ends of the elastic member 702 are respectively fixedly connected to the moving rod 701 and the upper tool holder 401. A pressure roller 703 is fixedly connected between the two moving rods 701. A rack structure is arranged on the moving rod 701. The moving rod 701 is meshed with the transmission gear 616.

[0036] Furthermore, the cutting component 4 further includes a bottom plate 415 fixedly connected to the lower part of the workbench 1. Two bidirectional lead screws 411 are rotatably connected to the top surface of the bottom plate 415. A lower tool holder 412 is arranged between the workbench 1 and the bottom plate 415. The lower tool holder 412 and the movable plate 301 are threadedly connected to the bidirectional lead screws 411. A push plate 413 is arranged on the lower tool holder 412. One end of the push plate 413 is rotatably connected to the lower tool holder 412, and the other end is connected to the workbench 1 through a steel wire rope 414.

[0037] Furthermore, the cutting component 4 further includes a first motor 416 fixedly connected to the bottom surface of the bottom plate 415. The output shaft of the first motor 416 is fixedly connected to one of the bidirectional lead screws 411. The bidirectional lead screws 411 are interconnected through a second synchronous belt assembly 417.

[0038] During specific operation, when cutting the optical film raw material 9, after the adjusting component 3 has adjusted the orientation of the cutting tool 402, the first motor 416 is started. The output shaft of the first motor 416 drives one of the bidirectional lead screws 411 to rotate. The bidirectional lead screws 411 achieve synchronous rotation through the second synchronous belt assembly 417, so that the upper tool holder 401 and the lower tool holder 412 approach each other. When the upper tool holder 401 and the lower tool holder 412 approach each other, the push plate 413 falls into the groove of the lower tool holder 412, making the push plate 413 in a horizontal position. When the upper tool holder 401 and the lower tool holder 412 continue to approach, the pressure roller 703 acts on the push plate 413, so that the optical film raw material 9 is pressed tightly, thereby reducing the movement or misalignment of the material during the cutting process, preventing problems such as wrinkling or folding, ensuring the accurate size of the cut product, ensuring that the cutting line is straight and clear, and improving the cutting quality.

[0039] Since the pressure roller 703 contacts the optical film raw material 9 first and presses the optical film raw material 9 tightly, but at this time the cutting tool 402 has not yet contacted the optical film raw material 9, the upper tool holder 401 and the lower tool holder 412 will still continue to approach. As a result, the pressure roller 703 squeezes the elastic member 702, causing the elastic member 702 to deform. The upper tool holder 401 moves downward relative to the moving rod 701. The movable rod 6021 and the piston 6022 are stationary relative to the moving rod 701, and the sealing cylinder 602 moves downward relative to the piston 6022. Then the sealing cylinder 602 inhales air through the pipeline and the one-way intake valve, thus completing the cutting of the optical film raw material 9.

[0040] After the cutting is completed, the first motor 416 is started. Then, the first motor 416 drives the upper tool holder 401 and the lower tool holder 412 to move away from each other. Then, the elastic member 702 resets, driving the moving rod 701 to move downward. Then, the moving rod 701 drives the transmission gear 616 to rotate through meshing transmission. The transmission gear 616 drives the second bevel gear 614 to rotate through the first synchronous belt assembly 615. The second bevel gear 614 drives the first bevel gear 613 to rotate through meshing transmission. Then, the first bevel gear 613 drives the first screw rod 605 to rotate, causing the first moving block 603 to move. When the first moving block 603 moves, it drives the high-pressure nozzle 606 to move. While the high-pressure nozzle 606 moves, it drives the incomplete gear 611 to move. The incomplete gear 611 realizes self-rotation through meshing transmission with the meshing rack 612. While the incomplete gear 611 rotates, it drives the high-pressure nozzle 606 to rotate. Thus, the movement and rotation of the high-pressure nozzle 606 are realized, expanding the cleaning range. At the same time, when the elastic member 702 resets, it drives the moving rod 701 to move downward. Then, the piston 6022 moves downward relative to the sealing cylinder 602. Then, the piston 6022 conveys the inhaled air to the first moving block 603 through the hose and finally sprays it out through the high-pressure nozzle 606. In this way, the cutting tool 402 is cleaned, ensuring the cleanliness of the surface of the cutting tool 402 and preventing debris of the optical film or the cutting material from adhering to the surface of the cutting tool 402, which may cause a decline in cutting quality or damage to the tool performance. The movement and rotation of the high-pressure nozzle 606 enable the sprayed gas to cover the entire working surface of the cutting tool 402. It should be added that when the upper tool holder 401 and the lower tool holder 412 continuously approach, the high-pressure nozzle 606 will move and rotate, but at this time, the sealing cylinder 602 is in the air suction state, so it will not affect the cutting.

[0041] When the upper tool holder 401 and the lower tool holder 412 move away from each other, the cut optical film falls onto the top surface of the push plate 413. And when the lower tool holder 412 moves downward, since one end of the push plate 413 is connected to the workbench 1 through the steel wire rope 414 and the other end is rotatably connected to the lower tool holder 412, when the lower tool holder 412 moves downward, an inclination angle will be formed. Then, the cut optical film will slide onto the conveyor belt 5 and be transported to the next cleaning process. After cleaning, the operator judges whether the cutting is complete through the boundary line 902, and the waste after cutting is wound up by the winding drum 802.

[0042] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
