Description

Technical Field

[0001] This invention relates to the field of fabric processing equipment technology, and in particular to a device for visual positioning and laser perforation of fabric. Background Technology

[0002] In the processing of clothing, home textiles, and industrial fabrics, it is often necessary to precisely punch holes at specific weave patterns or warp and weft intersections in the fabric to facilitate subsequent sewing or installation of accessories. Traditional methods rely entirely on manual operation: First, at least two employees need to work together to manually stretch and lay the fabric flat on a table; then, workers carefully observe the fabric surface with the naked eye, locate multiple standard weave patterns, and manually mark them with a marker; finally, the marked fabric is transferred to a laser cutting machine, and the laser head is manually adjusted to align with the marked points before starting the laser to punch holes.

[0003] This traditional work method has many drawbacks: First, the force cannot be precisely controlled when manually stretching the fabric, resulting in inconsistent fabric stretch lengths and excessive vertical fluctuations, which affects processing accuracy. Second, prolonged observation of fine textures with the naked eye can easily lead to visual fatigue among employees, resulting in deviations or omissions in position marking and unstable product yield. Third, using a marker pen to mark the fabric can not only cause dirt and increase subsequent cleaning costs, but the marking itself is also prone to error. Fourth, this workstation requires at least two employees to work together, resulting in high labor costs, low production efficiency, and difficulty in meeting the needs of modern intelligent manufacturing.

[0004] There is a need for a new type of fabric visual positioning and laser perforation equipment that can solve the problems mentioned above. Summary of the Invention

[0005] This invention provides a device for visual positioning and laser perforation of fabric. By technically modifying existing vision equipment, it solves the problems of cumbersome manual positioning operations and low processing efficiency in fabric perforation.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A device for visual positioning and laser perforation of fabric includes a machine base, a carrier, a rotary drive structure, a bottom rotating disk, a lower clamping module, an upper clamping module, a stretching drive assembly, a vision inspection module, a laser perforation module, and a main control system. The rotary drive structure is mounted on the machine base, and a horizontally arranged bottom rotating disk is mounted at the output end of the rotary drive structure. The carrier and the lower clamping module are mounted on the bottom rotating disk. The carrier is used to hold the fabric, and the lower clamping module is used to clamp the lower end of the fabric on the carrier. The stretching drive assembly and the upper clamping module are also mounted on the machine base. The assembly includes an upper clamping module for clamping the upper part of the fabric on the carrier, a stretching drive assembly for stretching and tensioning the fabric, and a vision inspection module and a laser drilling module arranged around the outer periphery of the bottom rotating disk. The vision inspection module and the laser drilling module are positioned facing the fabric on the carrier. The vision inspection module is used to scan and identify the fabric on the carrier, and the laser drilling module is used to drill holes at specific points on the fabric on the carrier. The rotation drive structure, the lower clamping module, the upper clamping module, the stretching drive assembly, the vision inspection module, the laser drilling module, and the main control system are electrically connected.

[0007] Preferably, the lower clamping module includes a clamping block, a horizontal slide rail, and a clamping block driving assembly. The clamping block is slidably mounted on the horizontal slide rail, and the clamping block driving assembly is used to drive the clamping block to slide horizontally along the horizontal slide rail. Four clamping blocks are distributed around the carrier on the bottom rotating disk, and the clamping blocks are used to clamp the fabric on the carrier.

[0008] Preferably, the clamping block has an arc-shaped surface on one side relative to the carrier that matches the outer wall of the carrier, and the arc-shaped surface is provided with anti-slip textures or an elastic pad.

[0009] Preferably, the stretching drive assembly includes a mounting bracket, a vertical slide rail, a vertical drive assembly, and an upper clamping module mounting base. The mounting bracket is mounted on the machine base, and the vertical slide rail and the vertical drive assembly are mounted on the mounting bracket. The upper clamping module mounting base is slidably mounted on the vertical slide rail. The vertical drive assembly is used to drive the upper clamping module mounting base to move up and down along the vertical slide rail. The upper clamping module is mounted on the upper clamping module mounting base.

[0010] Preferably, the visual inspection module includes a camera assembly and a light source, with the camera assembly positioned facing the fabric on the carrier.

[0011] Preferably, the laser drilling module includes a laser head and a two-dimensional moving platform. The laser head is mounted on the machine base via the two-dimensional moving platform, which is electrically connected to the main control system. The main control system is used to drive the laser drilling module to move in the horizontal plane to align with the drilling point based on the position coordinates identified by the vision inspection module.

[0012] Preferably, the main control system includes an image processing module and a motion control module; The image processing module is used to receive image data collected by the visual inspection module, identify fabric texture feature points and generate position coordinates; The motion control module is used to control the rotation angle of the rotation drive structure and the triggering timing of the laser drilling module according to the position coordinates.

[0013] Preferably, the machine is also equipped with a touch screen display.

[0014] A method of using a device for visual positioning and laser perforation of fabric includes the following steps: S1, the operator smoothly places the pre-cut tubular fabric onto the carrier; S2, Start the equipment. Under the control of the main control system, the clamping block drive assembly of the clamping module pushes the clamping block along the horizontal slide rail towards the carrier, clamping the lower edge of the fabric. At the same time, the upper clamping module operates to clamp the upper edge of the fabric. S3, the main control system controls the vertical drive component of the tension drive assembly to work according to the preset process parameters, which drives the upper clamping module to move upward along the vertical slide rail. The force sensor monitors the actual tension value in real time and feeds it back to the main control system. When the set tension value is reached, the vertical drive component stops and maintains its position, so that the fabric is flat and taut. S4. After the fabric is tensioned, the rotation drive structure starts to work, driving the bottom rotating disk and the carrier to rotate at a constant speed. During the rotation, the camera component of the vision inspection module continuously collects images of the fabric surface at a fixed frequency. The image processing algorithm built into the main control system analyzes the images in real time, identifies the texture feature points that need to be punched, and records the rotation angle and height position coordinates of each feature point. Since one rotation can cover the entire circumference of the fabric, a 360-degree panoramic scan is achieved, and the detection information is sent to the main control system in real time. S5, after a full rotation and scanning, the rotating drive structure drives the carrier to reverse, so that the fabric returns to the initial angle position, or stops directly at the drilling station corresponding to the laser drilling module. The motion control module of the main control system converts the previously recorded polar coordinate data into movement instructions for the two-dimensional moving platform, controls the laser drilling module to move to the corresponding height position, and at the same time, with the precise angle positioning of the bottom rotating disk, the laser head is aligned with each position that needs to be drilled. After alignment, the laser drilling module emits laser pulses to perform precise fixed-point drilling. S6. After all holes are drilled, each clamping module is released, and the operator removes the processed fabric to proceed to the next work cycle.

[0015] The beneficial effects of this invention are as follows: The newly developed fabric visual precision cutting equipment in this application only requires placing the prepared fabric onto the carrier, activating the cylinder of the tension drive component with the set tension value to drive the lower clamping module and the upper clamping module to move away from each other and perform a stretching action, then the carrier module rotates with the fabric, during which the camera module will identify and capture the texture position of the fabric surface through an algorithm, and finally the carrier rotates back, and the laser module performs pinpoint punching through the texture position identified by the camera module.

[0016] 1. High degree of automation: The fabric visual precision cutting equipment developed in this application only requires manual placement of the fabric onto the carrier, and the subsequent stretching, visual recognition, and punching processes are completed automatically, which greatly reduces the dependence on manual labor and lowers labor costs.

[0017] 2. Precise positioning: This application uses a high-precision vision inspection module to automatically identify the fabric texture, and with the help of a precise stretching drive component to control the fabric tension, it eliminates errors caused by uneven stretching force and visual fatigue, and significantly improves the accuracy and consistency of the punching position.

[0018] 3. To avoid fabric contamination, this application abandons the traditional marker dotting method, avoiding chemical contamination of the fabric and ensuring the cleanliness of the fabric.

[0019] 4. Improved efficiency: This application integrates rotation detection and laser drilling functions, realizing the integration of detection and processing, shortening material flow time, and effectively improving production efficiency. Attached Figure Description

[0021] The specific details of the present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0022] Please see Figure 1-4As shown, this invention provides a device for visual positioning and laser perforation of fabric, including a machine base 1, a carrier 2, a rotation drive structure 11, a bottom rotating disk 12, a lower clamping module 3, an upper clamping module 4, a stretching drive assembly 5, a visual inspection module 6, a laser perforation module 7, and a main control system. The rotation drive structure 11 is mounted on the machine base 1, and a horizontally arranged bottom rotating disk 12 is mounted on the output end of the rotation drive structure 11. The carrier 2 and the lower clamping module 3 are mounted on the bottom rotating disk 12. The carrier 2 is used to mount fabric 8, and the lower clamping module 3 is used to clamp the lower end of the fabric 8 on the carrier 2. The stretching drive assembly 5 is also mounted on the machine base 1. The upper clamping module 4 is used to clamp the upper end of the fabric 8 on the carrier 2. The tension drive assembly 5 is used to stretch and tension the fabric 8. A vision inspection module 6 and a laser drilling module 7 are also arranged on the outer periphery of the bottom rotating disk 12. The vision inspection module 6 and the laser drilling module 7 are set facing the fabric 8 on the carrier 2. The vision inspection module 6 is used to scan and identify the fabric 8 on the carrier 2, and the laser drilling module 7 is used to drill holes at fixed points on the fabric 8 on the carrier 2. The rotation drive structure 11, the lower clamping module 3, the upper clamping module 4, the tension drive assembly 5, the vision inspection module 6, the laser drilling module 7 and the main control system are electrically connected.

[0023] The rotation drive structure 11 uses a servo motor in conjunction with a high-precision reducer. The output end of the rotation drive structure 11 is vertically connected to and drives a horizontally arranged bottom rotating disk 12 to rotate. The rotation drive structure 11 is equipped with an angle encoder, which can accurately control the rotation angle of the bottom rotating disk 12, with a positioning accuracy of ±0.01°.

[0024] The carrier 2 is a cylindrical structure adapted to the fabric 8 tube. It is made of aluminum alloy and the surface is anodized, making it smooth and flat to avoid scratching the fabric 8.

[0025] Furthermore, the lower clamping module 3 includes a clamping block 31, a horizontal slide rail 32, and a clamping block 31 driving assembly. The clamping block 31 is slidably mounted on the horizontal slide rail 32, and the clamping block 31 driving assembly is used to drive the clamping block 31 to slide horizontally along the horizontal slide rail 32. Four clamping blocks 31 are distributed around the carrier 2 on the bottom rotating disk 12. The clamping blocks 31 are used to clamp the fabric 8 on the carrier 2.

[0026] Furthermore, in order to obtain a more stable clamping effect, the clamping block 31 is provided with an arc-shaped curved surface 311 that matches the outer wall of the carrier 2 on one side opposite to the carrier 2. The arc-shaped curved surface 311 is provided with anti-slip texture, which can increase the contact area and friction between the clamping block 31 and the fabric 8, making the clamping more stable, and effectively preventing the fabric 8 from being scratched or having clamp marks caused by sharp right-angle edges.

[0027] Furthermore, in order to enable the stretching drive assembly 5 to control the stretching force value so that the fabric 8 is stretched and straightened, the stretching drive assembly 5 includes a mounting bracket 51, a vertical slide rail 52, a vertical drive assembly 53, and an upper clamping module mounting seat 54. The mounting bracket 51 is mounted on the machine base 1. The vertical slide rail 52 and the vertical drive assembly 53 are mounted on the mounting bracket 51. The upper clamping module mounting seat 54 is slidably mounted on the vertical slide rail 52. The vertical drive assembly 53 is used to drive the upper clamping module mounting seat 54 to move up and down along the vertical slide rail 52. The upper clamping module 4 is mounted on the upper clamping module mounting seat 54.

[0028] Furthermore, the visual inspection module 6 includes a camera assembly and a light source, with the camera assembly positioned facing the fabric 8 on the carrier 2.

[0029] Furthermore, in order to achieve the functional effect of the laser drilling module 7, the laser drilling module 7 includes a laser head and a two-dimensional moving platform. The laser head is mounted on the machine base 1 through the two-dimensional moving platform. The two-dimensional moving platform is electrically connected to the main control system. The main control system is used to drive the laser drilling module 7 to move in the horizontal plane to align with the drilling point according to the position coordinates identified by the vision detection module 6.

[0030] The laser head of the laser punching module 7 is positioned directly over the fabric 8 on the carrier 2 to perform the punching operation. In this embodiment, the laser punching module 7 uses a CO2 radio frequency laser with a power of 150W, which is suitable for processing common clothing fabrics such as nylon and polyester, and features a small heat-affected zone and smooth cuts.

[0031] This application employs a high-precision vision inspection module 6 to automatically identify the fabric texture 8, and a precise stretching drive component 5 to control the fabric tension. This eliminates errors caused by uneven manual stretching force and visual fatigue, significantly improving the accuracy and consistency of the drilling position. Laser drilling itself has the characteristics of being non-contact and having minimal thermal effect, resulting in smooth, burr-free hole walls.

[0032] Furthermore, the main control system includes an image processing module and a motion control module; The image processing module is used to receive image data collected by the visual inspection module 6, identify the feature points of the fabric 8 texture, and generate position coordinates. The motion control module is used to control the rotation angle of the rotation drive structure 11 and the triggering timing of the laser drilling module 7 according to the position coordinates.

[0033] The image processing module receives image data acquired by the vision inspection module 6, identifies fabric texture feature points 8 using built-in image recognition algorithms (such as edge detection and feature matching), and generates the corresponding polar coordinate positions (rotation angle and height position) of these feature points. The motion control module controls the rotation angle of the rotation drive structure 11 and the triggering timing and drilling parameters of the laser drilling module 7 based on the position coordinates generated by the image processing module.

[0034] Furthermore, in order to achieve a more convenient control effect, a touch screen display 9 is also installed on the machine tool 1.

[0035] A method for using a device for visual positioning and laser perforation of fabric 8 includes the following steps: S1, the operator smoothly places the pre-cut tubular fabric 8 onto the carrier 2; S2, the equipment is started. Under the control of the main control system, the clamping block 31 drive assembly of the clamping module 3 pushes the clamping block 31 along the horizontal slide rail 32 toward the carrier 2, clamping the lower edge of the fabric 8. At the same time, the upper clamping module 4 is activated, clamping the upper edge of the fabric 8. S3, the main control system controls the vertical drive component 53 of the tension drive component 5 to work according to the preset process parameters, driving the upper clamping module 4 to move upward along the vertical slide rail 52. The force sensor monitors the actual tension value in real time and feeds it back to the main control system. When the set tension value is reached, the vertical drive component 53 stops moving and maintains its position, so that the fabric 8 is flat and taut. S4, after the fabric 8 is tensioned, the rotation drive structure 11 starts to work, driving the bottom rotating disk 12 and the carrier 2 to rotate at a constant speed. During the rotation, the camera component of the vision inspection module 6 continuously collects images of the surface of the fabric 8 at a fixed frequency. The image processing algorithm built into the main control system analyzes the images in real time, identifies the texture feature points that need to be punched, and records the rotation angle and height position coordinates of each feature point. Since one rotation can cover the entire circumference surface of the fabric 8, a 360-degree panoramic scan is achieved, and the detection information is sent to the main control system in real time. S5, after the complete one-turn scan, the rotating drive structure 11 drives the carrier 2 to reverse, so that the fabric 8 returns to the initial angle position, or stops directly at the drilling station corresponding to the laser drilling module 7. The motion control module of the main control system converts the previously recorded polar coordinate data into the movement command of the two-dimensional moving platform, controls the laser drilling module 7 to move to the corresponding height position, and at the same time, with the precise angle positioning of the bottom rotating disk 12, the laser head is aligned with each position that needs to be drilled. After alignment, the laser drilling module 7 emits laser pulses to perform precise fixed-point drilling. S6, after all holes are drilled, each clamping module is released, and the operator removes the processed fabric 8, and then the next work cycle can begin.

[0036] The newly developed fabric 8 visual precision cutting equipment in this application only requires placing the prepared fabric 8 on the carrier 2, activating the cylinder of the tension drive component 5 with the set tension value to drive the lower clamping module 3 and the upper clamping module 4 to move away from each other and perform a stretching action. Then, the carrier 2 module carries the fabric 8 to rotate. During this time, the camera module will identify and capture the texture position on the surface of the fabric 8 through an algorithm. Finally, the carrier 2 rotates back, and the laser module performs pinpoint punching through the texture position identified by the camera module.

[0037] 1. High degree of automation: The fabric visual precision cutting equipment developed in this application only requires manual placement of the fabric onto the carrier, and the subsequent stretching, visual recognition, and punching processes are completed automatically, which greatly reduces the dependence on manual labor and lowers labor costs.
