Description

Technical Field

[0001] This utility model belongs to the field of die positioning technology, and in particular relates to a positioning mechanism for positioning the die of a cutting machine. Background Technology

[0002] Cutting machines are commonly used for stamping and cutting non-metallic materials such as rubber and foam. The machine applies pressure to a die of a specific shape, directly stamping and cutting the material surface. Different die shapes and specifications facilitate the cutting of various specified parts, and batch cutting helps improve production efficiency. However, existing cutting machines often require different dies for different workpieces, necessitating frequent adjustments. Due to the varying die specifications, existing die fixing structures typically require positioning adjustments after installation. In current technology, die positioning in cutting machines primarily relies on manual calibration or mechanical position sensors. While manual calibration is flexible, it is inefficient and its accuracy is heavily influenced by the operator's skill. Mechanical position sensors, while improving positioning accuracy, are often limited by complex and variable working environments, such as lighting and material thickness. Therefore, a die positioning mechanism needs to be developed to improve the accuracy and efficiency of die positioning in cutting machines. Utility Model Content

[0003] The purpose of this utility model is to provide a positioning mechanism for positioning the die of a cutting machine, which aims to solve the technical problem in the prior art that cutting machines often need to use different dies to process different workpieces during use, and therefore often need to adjust the different dies.

[0004] To achieve the above objectives, this utility model provides a positioning mechanism for positioning a cutting machine die, comprising a mounting base plate, a linear module, and a vision positioning device. The mounting base plate is disposed on the worktable surface of the cutting machine and located at the side end of the cutting machine die. The linear module is disposed on the mounting base plate, and the vision positioning device is disposed on the drive end of the linear module. The linear module drives the vision positioning device to move back and forth in the worktable direction. The linear module includes a module base, a servo motor, a lead screw, and a coupling. The module base is an upward-opening cavity disposed on the mounting base plate. The lead screw is disposed within the cavity of the module base, and its two ends are rotatably connected to the two ends of the module base. The servo motor is disposed on one side of the module base, and its drive end is connected to the lead screw via a coupling to drive the lead screw to rotate. The bottom end of the vision positioning device is provided with a nut seat that mates with the lead screw, and the vision positioning device is slidably connected above the module base.

[0005] Furthermore, the visual positioning device includes a slider and a CCD camera. A nut seat is located at the lower end of the slider, which is slidably connected to the module base, and the CCD camera is mounted on the slider.

[0006] Furthermore, the visual positioning device also includes an infrared sensor, which is mounted on the slider.

[0007] Furthermore, the module base has triangular grooves on both sides, and triangular limiting blocks extend from both sides of the bottom end of the slider towards the triangular grooves, with the triangular limiting blocks cooperating with the triangular grooves.

[0008] Furthermore, it also includes a baffle plate, which is set on one side of the module base and located between the die and the module base. The baffle plate is provided with a clearance hole for preventing air from entering the CCD camera and infrared sensor.

[0009] The positioning mechanism for positioning the die-cutting machine provided in this embodiment of the utility model has at least one of the following technical effects: The mounting base plate is used to fix and support the entire device, ensuring a stable installation position; the linear module drives the lead screw to rotate via a servo motor, thereby driving the vision positioning device to make precise forward and backward linear movements on the worktable; the vision positioning device is slidably connected above the module base via a nut seat that cooperates with the lead screw, enabling precise positioning and detection under the drive of the linear module.

[0017] In one embodiment of this utility model, reference is made to Figure 1As shown, a positioning mechanism for positioning a cutting machine die is provided, including a mounting base plate 100, a linear module 200, and a vision positioning device 300. The mounting base plate 100 is disposed on the worktable surface of the cutting machine and located at the side end of the cutting machine die. The linear module 200 is disposed on the mounting base plate 100, and the vision positioning device 300 is disposed on the drive end of the linear module 200. The linear module 200 is used to drive the vision positioning device 300 to move back and forth in the worktable direction. The linear module 200 includes a module base 210, a servo motor 220, a lead screw 230, and a coupling 240. The module base 210 is an upward-opening cavity. The module base 210 is mounted on the mounting base plate 100. The lead screw 230 is mounted in the cavity of the module base 210, and the two ends of the lead screw 230 are rotatably connected to the two ends of the module base 210. The servo motor 220 is mounted on one side of the module base 210, and the drive end of the servo motor 220 is connected to the lead screw 230 through the coupling 240 to drive the lead screw 230 to rotate. The bottom end of the vision positioning device 300 is provided with a nut seat that cooperates with the lead screw 230. The vision positioning device 300 is slidably connected above the module base 210. In this embodiment, the mounting base 100 is used to fix and support the entire device, ensuring a stable installation position. The linear module 200 drives the lead screw 230 to rotate via the servo motor 220, thereby driving the vision positioning device 300 to make precise linear movements back and forth on the worktable. The vision positioning device 300 is slidably connected above the module base 210 through a nut seat that cooperates with the lead screw 230, enabling precise positioning and detection under the drive of the linear module 200. The mounting base 100 is fixed on the worktable of the cutting machine to ensure the stability and accuracy of the device. Then, the servo motor 220 drives the lead screw 230 to rotate via the coupling 240. The rotational motion of the lead screw 230 is converted into linear motion of the vision positioning device 300 through the movement of the nut seat. Relying on the precise drive of the linear module 200, the vision positioning device 300 achieves precise positioning and detection of the cutting die position on the worktable, thereby effectively improving the accuracy and efficiency of the cutting process.

[0018] Specifically, refer to Figure 1 As shown, the visual positioning device 300 includes a slider 320 and a CCD camera 330. A nut seat is located at the lower end of the slider 320, which is slidably connected to the module base 210. The CCD camera 330 is mounted on the slider 320. In this embodiment, the CCD camera 330 is driven to slide on the worktable by the linear module 200. The imaging end of the CCD camera 330 captures images from multiple angles past the installed die. The visual positioning technology uses the image information acquired by the CCD camera 330 and analyzes and identifies it through image processing technology to determine the position of the die. This technology can not only flexibly cope with various working environments but also provide high positioning accuracy.

[0019] Specifically, refer to Figure 1 As shown, the visual positioning device 300 also includes an infrared sensor 340, which is mounted on the slider 320. In this embodiment, visual positioning by the CCD camera 330 may be limited in low-light or complex background environments. Infrared positioning technology determines the position of an object by emitting infrared rays and receiving reflected signals. This method has high reliability and fast response speed in stable working environments. Combining visual positioning with infrared positioning technology can compensate for the shortcomings of each, thereby achieving accurate die-cutting positioning in a wider range of application scenarios and improving the efficiency and quality of cutting operations.

[0020] Specifically, refer to Figure 1 As shown, the module base 210 has triangular grooves 211 on both sides, and triangular limiting blocks 321 extend from both sides of the bottom end of the slider 320 towards the triangular grooves 211, with the triangular limiting blocks 321 cooperating with the triangular grooves 211. In this embodiment, the slider 320 is slidably connected to the module base 210 through the cooperation between the triangular grooves 211 and the triangular limiting blocks 321, while preventing the slider 320 from moving during the process.

[0021] Specifically, refer to Figure 1 As shown, it also includes a baffle 400, which is disposed on one side of the module base 210 and located between the die-cutting mold and the module base 210. The baffle 400 has a clearance hole 410, which is used to prevent the CCD camera 330 and the infrared sensor 340 from entering. In this embodiment, the baffle 400 is used to protect the linear module 200 and prevent foreign objects from entering the linear module 200 and affecting the accuracy of the linear module 200 driving the visual positioning device 300. The clearance hole 410 is used to prevent the shooting end of the CCD camera 330 and the emitting end of the infrared sensor 340 from entering.

[0022] The rest of this embodiment is the same as that in Embodiment 1. Features not explained in this embodiment are explained using the methods in Embodiment 1, and will not be repeated here.
