Description

Technical Field

[0001] This utility model relates to the field of printing film cutting technology, specifically a fully automatic cutting machine based on machine vision. Background Technology

[0002] Printing film is a special thin film material used in the printing process.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0026] Please see Figure 1-7 This embodiment provides a technical solution: a fully automatic cutting machine based on machine vision, including a cutting table 1 and a cutting mechanism 4;

[0027] A cutting frame 2 is fixedly connected to the front end of the upper surface of the cutting table 1, a positioning frame 3 is fixedly connected to the middle of the upper surface of the cutting table 1, a feeding rack 21 is provided on the rear side of the cutting table 1, a controller 28 is provided on the right end of the upper surface of the cutting frame 2, and a display screen 29 is provided on the left end of the upper surface of the cutting frame 2. The input end of the controller 28 is electrically connected to an external power supply, and the input end of the display screen 29 is electrically connected to the output end of the controller 28.

[0028] The cutting mechanism 4 includes a cutter holder 41, a lifting plate 43, a guide frame 44, a guide wheel 45, a cutter seat 46, and a cutting blade 47. The cutter holder 41 is located inside the cutting frame 2. Anti-collision plates 5 are fixedly connected to both ends of the cutter holder 41. The lifting plate 43 is vertically slidably connected inside the cutter holder 41. (A proximity switch can be installed in the middle of the cutter holder 41. The proximity switch can be an IGS204. When the lifting plate 43 moves within the sensitive area of ​​the proximity switch, the intensity of the eddy current effect changes with distance. The detection circuit of the proximity switch can calculate the displacement of the lifting plate 43 by monitoring the change of oscillation parameters in real time. When the lifting plate 43 reaches the specified displacement, the controller 28...) The proximity switch provides feedback, causing the external air pump to stop supplying air to the telescopic cylinder 42. The lower end of the lifting plate 43 is fixedly connected to a guide frame 44. The lower end of the guide frame 44 is rotatably connected to evenly distributed guide wheels 45. The lower end of the front surface of the guide frame 44 is fixedly connected to a tool holder 46. The lower end of the tool holder 46 is fixedly connected to a cutting blade 47. The cutting mechanism 4 also includes a telescopic cylinder 42, which is located inside the tool holder 41. The lower end of the piston rod of the telescopic cylinder 42 is fixedly connected to the rear end of the lifting plate 43. The air port of the telescopic cylinder 42 is connected to the air outlet of the external air pump through an air pipe. The input end of the external air pump is electrically connected to the output end of the controller 28.

[0029] The positioning frame 3 is equipped with a vision camera 6 at its upper end and a mounting frame 7 is fixedly connected to the middle of the positioning frame 3. Both ends of the mounting frame 7 are equipped with supplementary lights 8. (The controller 28 operates the supplementary lights 8 to ensure even light distribution on the printing film and prevent insufficient light in some areas from affecting the image acquisition effect of the vision camera 6.) The vision camera 6 is bidirectionally electrically connected to the controller 28, and the input ends of the two supplementary lights 8 are electrically connected to the output ends of the controller 28. When the printing film passes the positioning frame 3 on the upper surface of the cutting table 1, the controller 28 activates the vision camera 6. The vision camera 6 takes pictures and identifies the pattern position and outline, saves the data, and sends the image data to the signal receiving end of the controller 28 in real time. The controller 28 calculates the deviation between the actual coordinates of the pattern and the preset coordinates, sets a compensation value, and controls the printing film conveying distance accordingly. When the printing film reaches the designated position, the controller 28 monitors the operation status of the conveyor roller 10 based on the information feedback from the vision camera 6.

[0030] The cutting frame 2 is equipped with a servo motor, which drives the guide rail slider 9. The front end of the moving terminal of the guide rail slider 9 is fixedly connected to the rear end of the tool holder 41. (Alternatively, proximity switches can be installed at both ends of the guide rail slider 9. When the tool holder 41 reaches the sensing area of ​​the proximity switch, the controller 28 closes the guide rail slider 9 to prevent the tool holder 41 from colliding with the cutting frame 2. At the same time, the anti-collision plate 5 provides lateral anti-collision protection for the tool holder 41.) The input end of the guide rail slider 9 is electrically connected to the output end of the controller 28. When the printing film stops moving, the controller 28 activates the external air pump. An external air pump injects gas into the telescopic cylinder 42 through an air pipe. The piston rod of the telescopic cylinder 42 extends, pushing the lifting plate 43 downward. The downward movement of the lifting plate 43 causes the guide frame 44 to move downward, which in turn causes the cutting blade 47 to move downward. When the cutting blade 47 reaches the designated area, the external air pump stops supplying air into the telescopic cylinder 42. At the same time, the controller 28 enables the guide rail slider 9 to move. The moving terminal of the guide rail slider 9 moves from right to left, causing the tool holder 41 to move. The movement of the tool holder 41 causes the cutting blade 47 to move, and the cutting blade 47 cuts the printed film.

[0031] The following configuration is provided: a motor 22 is installed on the upper end of the left side surface of the feeding rack 21; a feeding roller 23 is fixedly connected to the right end of the output shaft of the motor 22; a printing film roll 24 is installed in the middle of the outer surface of the feeding roller 23; a guide roller 25 is rotatably connected to the rear end of the cutting table 1; a feeding roller 26 is rotatably connected to the rear end of the cutting table 1; a tension mechanism 27 is installed in the middle of the rear surface of the cutting table 1; symmetrically distributed pressure plates 30 are fixedly connected to the middle of the upper surface of the cutting table 1; a conveyor roller 10 is rotatably connected inside the cutting rack 2; the input end of the motor 22 is electrically connected to the output end of the controller 28; the controller 28 enables the motor 22 to operate; the output shaft of the motor 22 rotates, driving the feeding roller 23 to rotate; the feeding roller 23 and the conveyor roller 10 rotate to feed the printing film; the printing film moves from back to front, passing sequentially through the upper end of the guide roller 25, the lower end of the tension roller of the tension mechanism 27, the upper end of the feeding roller 26, between the two pressure plates 30, and the lower end of the conveyor roller 10.

[0032] The cutting table 1 has a material ejector 11 at its front end. Guide rods 14 are fixedly connected to both the left and right ends of the material ejector 11. A lower pressure plate 16 is slidably connected between the two guide rods 14 via a linear bearing 15. (In the initial state, the upper surface of the lower pressure plate 16, the upper surface of the cutting table 1, and the upper surface of the material ejector 19 are on the same horizontal plane.) Two symmetrically distributed telescopic cylinders 12 are installed at the upper end of the material ejector 11. Upper pressure plates 13 are fixedly connected to the lower ends of the piston rods of the two telescopic cylinders 12. The two upper pressure plates 13 are vertically aligned with the lower pressure plate 16. The lower surface of the lower pressure plate 16 and the bottom wall of the material ejector 11 are connected... Two springs 17 are installed between the guide rods 14. Each spring 17 is fitted onto the outer surface of an adjacent guide rod 14. The upper pins of each spring 17 can be engaged with the lower end of the lower pressure plate 16 via clips, and the lower pins of each spring 17 can also be engaged with the base plate of the discharge rack 11 via clips. Periodically, the clips on the upper and lower pins of the spring 17 are closed, the base plate of the discharge rack 11 is removed, and the springs 17 are moved from top to bottom. The old springs 17 are removed, and new springs 17 are fitted onto the outer surface of the corresponding guide rod 14. The clips on the new springs 17 are then re-engaged, thus achieving periodic replacement of the springs 17 and preventing them from aging. (To mitigate the impact on the resetting effect of the lower pressure plate 16), mounting plates 18 are fixedly connected to both ends of the front surface of the cutting table 1. A discharge plate 19 is fixedly connected to the upper end between the two mounting plates 18. The air ports of the two telescopic cylinders 11 are connected to the air outlet of an external air pump through air pipe 2. After the printing film is cut, the external air pump supplies air to the telescopic cylinder 12 through air pipe 2. The extension of the piston rod of the telescopic cylinder 12 pushes the adjacent upper pressure plate 13 downward. The downward movement of the upper pressure plate 13 pushes the cut printing film downward. When the upper pressure plate 13 moves down to contact the lower pressure plate 16, the upper pressure plate 13 pushes the lower pressure plate 16 downward, pressing down. Under the vertical limiting guidance of the linear bearing, plate 16 moves downward between the two guide rods 14. The downward movement of the lower pressure plate 16 causes the two springs 17 to be elastically compressed, thereby completely separating the cut printing film near the center of the cutting frame 2 from the uncut portion of the printing film. Then, the external air pump draws air from the inside of the telescopic cylinder 12 through the air pipe 2, causing the piston rod of the telescopic cylinder 12 to move upward. The upward movement of the piston rod of the telescopic cylinder 12 drives the adjacent upper pressure plate 13 to move upward. The elastic force of the spring 17 pushes the lower pressure plate 16 to move upward, realizing the reset of the lower pressure plate 16. Then, under the guidance of the discharge plate 19, the cut printing film is removed.

[0033] Among them, an electrical box 20 is set in the middle of the left side surface of the cutting table 1, and the main unit of the controller 28 and the external air pump can be stored inside the electrical box 20.

[0034] The working principle of the fully automatic cutting machine based on machine vision provided by this utility model is as follows: During operation, the operator first places the cutting table 1, the cutting frame 2, and other mechanisms stably in the horizontal working area. After stable placement, the controller 28 activates the motor 22. The output shaft of the motor 22 rotates, driving the feeding roller 23 to rotate. The rotation of the feeding roller 23 feeds the printing film. The printing film moves from back to front, passing sequentially through the upper end of the guide roller 25, the lower end of the tension roller of the tension mechanism 27, the upper end of the feeding roller 26, between the two pressure plates 30, and the lower end of the conveyor roller 10, before reaching the cutting area. When the printing film passes the positioning frame 3 on the upper surface of the cutting table 1, the controller 28 activates the vision camera 6. The vision camera 6 takes a picture and recognizes the pattern. The position and outline are recorded, data is saved, and image data is sent to the signal receiving end of controller 28 in real time. Controller 28 calculates the deviation between the actual coordinates of the pattern and the preset coordinates, sets compensation values, and controls the printing film conveying distance accordingly. When the printing film reaches the designated position, controller 28 controls the operation of motor 22 based on feedback from vision camera 6. When the printing film stops moving, controller 28 activates external air pump. External air pump injects gas into telescopic cylinder 42 through air pipe. The piston rod of telescopic cylinder 42 extends, pushing lifting plate 43 downward. Lifting plate 43 moves downward, driving guide frame 44 downward. Guide frame 44 moves downward, driving cutting blade 47 downward. When cutting blade 47 reaches the designated area, external air pump stops injecting gas into telescopic cylinder 42. Cylinder 42 is supplied with air, and controller 28 simultaneously controls the movement of guide rail slider 9. The moving terminal of guide rail slider 9 moves from right to left, driving the tool holder 41 to move. The movement of tool holder 41 drives the cutting blade 47 to move, and the cutting blade 47 cuts the printing film. After the printing film is cut, the cutting blade 47 moves upward and then presses the film. An external air pump supplies air to telescopic cylinder 12 through air pipe 2. The extension of the piston rod of telescopic cylinder 12 pushes the adjacent upper pressure plate 13 downward. The downward movement of upper pressure plate 13 pushes the cut printing film downward. When upper pressure plate 13 moves downward to contact lower pressure plate 16, upper pressure plate 13 pushes lower pressure plate 16 downward. Under the vertical limiting guide of linear bearing, lower pressure plate 16 moves downward between two guide rods 14. The downward movement of lower pressure plate 16 makes... The two springs 17 are elastically compressed, causing the end of the cut printing film near the center of the cutting frame 2 to completely separate from the uncut portion of the printing film. Then, an external air pump draws air from the inside of the telescopic cylinder 12 through the air pipe 2, causing the piston rod of the telescopic cylinder 12 to move upward. The upward movement of the piston rod of the telescopic cylinder 12 drives the adjacent upper pressure plate 13 to move upward, and the elastic force of the spring 17 pushes the lower pressure plate 16 to move upward, realizing the reset of the lower pressure plate 16. Then, under the guidance of the discharge plate 19, the cut printing film is removed. This integrates multiple processes such as feeding, identification, positioning, cutting, and receiving into one machine. Through the information interaction between the vision camera 6 and the controller 28, real-time printing film pattern recognition and compensation are realized, thereby completing fully automated high-precision adaptive cutting.It achieved unattended continuous operation.

[0035] It is worth noting that the visual camera 6 disclosed in the above embodiments can be MV-CU060, the controller 28 can be MT-6051IP, and the display screen 29 can be D070. The controller 28 controls the operation of the visual camera 6, the guide rail slider 9, the motor 22, the display screen 29, and the external air pump using methods commonly used in the prior art.

[0036] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
