Description

Technical Field

[0001] This utility model relates to the field of shoe material machinery, specifically to a vision-guided cutting machine. Background Technology

[0002] As the material used for shoe uppers, after they are made, they still need to undergo die-cutting and trimming operations, which is the most critical process for shoe uppers.

[0003] Chinese invention patent announcement number CN 104257017 B discloses a stepping rotary shoe material punching machine. Its structure includes a gantry frame, a rotary punching head, and a punching base plate. A transverse lead screw driven by a first motor is mounted on the suspension beam of the gantry frame. The rotary punching head is positioned below the suspension beam of the gantry frame and reciprocates laterally. The rotary punching head has a nut threadedly connected to the transverse lead screw. The punching base plate is mounted on the punching machine worktable below the rotary punching head. The rotary punching head includes a slide block, a die mounting base, a pulley, a sleeve, a mandrel, and a hydraulic cylinder assembly. The slide block slides on a transverse guide rail. The cylinder assembly is fixedly installed on the cantilever beam of the gantry frame. The nut is fixedly connected to the slide block. The cylinder assembly includes a stationary and a moving part. The stationary part is fixed on the slide block. The lower end of the moving part is fixedly connected to the sleeve through a flange. The mandrel is rotatably disposed in the inner hole of the sleeve. The pulley is movably disposed on the outer circle of the sleeve. The mandrel and the pulley are fixedly installed on the top of the die mounting base. The die mounting base is disposed against the bottom of the sleeve. The pulley and the pulley are connected by belt drive. The pulley is mounted on the output shaft of the second motor. The second motor is mounted on the flange.

[0004] The above-mentioned structural operation process includes: 1. Vertical blanking action of the die: When pressurized oil enters the oil inlet pipe, it pushes the cylinder body downward, thus pushing the die downward through the flange, sleeve, and die mounting base to perform the blanking action. Conversely, when pressurized oil enters the oil inlet pipe, it pushes the cylinder body upward, thereby driving the die upward to return to its original position; 2. Lateral stepping reciprocating action of the die: When the first motor is working, it drives the lateral lead screw to rotate intermittently, thus driving the slide 5, the entire blanking head, and the die to perform a lateral stepping reciprocating action through the nut 4; 3. Rotation action of the die: When the second motor is working, it drives the pulley to rotate through the belt, and the rotation of the pulley drives the die mounting base and the die to rotate. Because the die can move vertically, laterally, and rotate during operation, the combination of these three actions makes the cutting interval of the shoe material material more compact. After cutting, as little scrap material is left on the shoe material material, more shoe uppers, midsoles and other shoe material products can be cut from the same area of ​​rubber sheet, thereby saving shoe material material waste and reducing production costs.

[0005] The above results have the following drawbacks: 1. When workers place the rubber sheet, they need to position it at a certain angle and location, which requires a high level of attention from the workers, resulting in low productivity; 2. During the operation, workers need to manually place the rubber sheet on the blanking base plate under the die, which poses certain safety hazards. Utility Model Content

[0006] To address the aforementioned problems, the purpose of this utility model is to provide a vision-based cutting machine that is highly efficient and safe to operate.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a vision-guided die-cutting machine, comprising a frame, on which a die that can move up and down and rotate independently is mounted, and a base plate is provided below the die. The base plate is characterized by having a conveyor belt, driven by a first motor to transport shoe material forward and by a second motor to slide left and right. A vision automatic recognition device is also mounted on the frame, comprising a camera installed above the input end of the conveyor belt. During operation, the camera captures shoe material information, which is then processed by the control software of the vision automatic recognition device to control the die to move up and down and rotate, and the conveyor belt to transport shoe material and slide left and right.

[0008] A base plate is mounted on the frame, which is located below the punching die. A transverse guide rail is provided on the base plate, and a slide block is mounted on the guide rail and slide block along it. The conveyor belt is mounted on the slide block. The output shaft of the second motor is connected to a lead screw, which is threadedly connected to the slide block.

[0009] A top plate is connected above the base plate via a guide rod. A slidable lifting plate is sleeved on the guide rod. A rotatable rotating seat is installed on the lifting plate. The punch is installed on the rotating seat. A third motor is connected to the side end of the lifting plate. The output shaft of the third motor is connected to the rotating seat via a belt. A lifting control mechanism for controlling the lifting of the die is also installed on the top plate.

[0010] The lifting control mechanism includes a sleeve connected to the top plate, a rotatable threaded rod inside the sleeve, a fourth motor installed at the side end of the sleeve, the output shaft of the fourth motor being connected to the threaded rod via a transmission belt, and a lifting sleeve also installed inside the sleeve and threadedly connected to the threaded rod, the lower end of the lifting sleeve being connected to the lifting plate.

[0011] The beneficial effects of this utility model are: workers or robotic arms randomly place shoe materials at the input end of the conveyor belt, and the camera in the vision automatic recognition device captures and positions them. Then, the vision automatic recognition device controls the conveyor belt to transport the sheet material to the bottom of the punching die, and controls the punching die to perform rotation, alignment and punching actions. This greatly improves the punching efficiency of the punching die, achieving the technical effect of high production efficiency and safe operation.

[0016] The present invention will be described in detail below through embodiments, which are only used to further illustrate the present invention and should not be construed as limiting the scope of protection of the present invention.

[0017] like Figure 1 — Figure 3 As shown, this embodiment discloses a vision-based die-cutting machine, including a frame 1. A die 2 that can move up and down and rotate on the frame 1 is mounted on the frame 1. A base plate 3 is provided below the die 2, and a conveyor belt 4 is provided on the base plate 3. The conveyor belt 4 is controlled by a first motor 5 to move forward and by a second motor 6 to move left and right. A vision automatic recognition device is also installed on the frame 1. The vision automatic recognition device is equivalent to the control system of the equipment. The vision automatic recognition device includes a camera 7, which is installed above the input end of the conveyor belt 4. During operation, the camera 7 captures the shoe material information, which is then processed by the control software of the vision automatic recognition device. The vision automatic recognition device then controls the die 2 to move up and down and rotate, and the conveyor belt to move the shoe material and slide left and right. In this way, the sheet material can be accurately delivered to the bottom of the die 2. The die 2 rotates and adjusts its position according to the information of the sheet material, and then performs die-cutting. The die-cut sheet material is output with the conveyor belt 4.

[0018] A base plate 3 is mounted on the frame 1, located below the punch die 2. A transverse guide rail 8 is provided on the base plate 3, and a sliding block is mounted on the guide rail 8. A conveyor belt 4 is mounted on the sliding block. The output shaft of the second motor 6 is connected to a lead screw, which is threadedly connected to the sliding block. This structure allows the second motor 6 to control the left and right movement of the sliding block, thereby controlling the left and right movement of the conveyor belt 4. This enables the alignment of randomly placed sheet metal with the punch die 2. The second motor 6 is controlled by a vision automatic recognition device.

[0019] A top plate 9 is connected to the top of the base plate 3 via a guide rod 10. A slidable lifting plate 12 is sleeved on the guide rod 10, and a rotatable rotating seat 11 is mounted on the lifting plate 12. The die 2 is mounted on the rotating seat 11. A third motor 13 is connected to the side end of the lifting plate 12. The output shaft of the third motor 13 is connected to the rotating seat 11 via a belt 14. A lifting control mechanism 1 for controlling the lifting and lowering of the die is also installed on the top plate 9. This structure allows the die to rotate while also reliably lifting and lowering, ensuring that the die is accurately aligned with the shoe material below. The third motor 13 is also controlled by a vision automatic recognition device.

[0020] The lifting control mechanism 1 includes a sleeve 16 connected to the top plate 9. A rotatable threaded rod is installed inside the sleeve 16. A fourth motor 12 is mounted on the side end of the sleeve 16. The output shaft of the fourth motor 12 is connected to the threaded rod via a transmission belt. A lifting sleeve 13, threadedly connected to the threaded rod, is also installed inside the sleeve 16. The lower end of the lifting sleeve 13 is connected to the lifting plate 12. The fourth motor 12 is controlled by a vision automatic recognition device. When the fourth motor 12 drives the threaded rod to rotate, it can drive the lifting plate 12 to rise and fall, thereby effectively controlling the lifting of the die-cutting mold. The structure is reliable and stable.

[0021] Using the above technical solution, workers or robotic arms randomly place shoe materials at the input end of the conveyor belt 4, and the camera 7 in the vision automatic recognition device captures and positions them. Then, the vision automatic recognition device controls the conveyor belt 4 to transport the sheet material to the bottom of the die 2, and controls the die 2 to perform rotation, alignment and punching actions. This greatly improves the punching efficiency of the die 2, achieving the technical effect of high production efficiency and safe operation.
