Description

Technical Field

[0001] This utility model belongs to the field of vision cutting machine technology, specifically a vision cutting machine. Background Technology

[0002] A vision cutting machine is an intelligent device that integrates machine vision technology and a cutting system. It acquires material images in real time using a high-resolution camera or industrial camera, and automatically identifies contours, locates features, and generates cutting paths using image processing algorithms, achieving high-precision, automated cutting operations. Its core components include a vision system, a motion control system, cutting tools (such as laser heads, vibrating blades, and drag blades), and intelligent software, allowing for flexible adaptation to different materials (such as fabrics, leather, metals, acrylic, and PCB boards). During operation, the machine automatically compensates for material deformation or positional deviations through image recognition. For example, when processing high-elasticity printed fabrics in the clothing industry, it can correct pattern distortion through deformation matching algorithms, ensuring smooth, error-free cutting edges.

[0003] CN202321065739.1 discloses a vibratory knife cutting machine using a wide-scanning camera. The wide-scanning camera is set vertically on the worktable. By precisely controlling the movement of the wide-scanning camera along the vertical direction of the crossbeam, it can scan and capture the feature information such as the outline, pattern, and markings of the processed material on the worktable in one go and output it to the PC. The accompanying image processing software is used to process the data and convert the processed image data into processing trajectory parameters, which are then sent to the vibratory knife cutting machine to perform cutting work that matches the material pattern.

[0004] In the above technical solution, the camera identifies the position and shape of the workpiece to achieve visual positioning, and the drive mechanism drives the laser cutting mechanism to move to cut the material. However, when fixing the fabric roll, a shaft needs to be passed through the paper tube of the fabric roll, and then the two ends of the shaft are placed on the fixing device to feed the material. When replacement is needed, the shaft must first be removed from the fixing device, then pulled out of the paper tube, and then inserted into the paper tube of the new fabric roll before being placed on the fixing device, which is troublesome.

[0031] 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.

[0032] Example 1

[0033] refer to Figures 1-3 A vision cutting machine includes a frame 1, a conveying unit 2, a cutting module 3, and a camera assembly 12 mounted on the frame 1. The conveying unit 2 is provided with a longitudinal drive mechanism 23. The cutting module 3 is connected to the longitudinal drive mechanism 23. The camera assembly 12 is located above the conveying unit 2. The machine also includes a feeding unit 5, which is located at one end of the frame 1 and adjacent to the input end of the conveying unit 2.

[0034] The feeding unit 5 includes a pair of support rollers 55 and a symmetrically arranged telescopic mechanism 51. The pair of support rollers 55 are rotatably connected to the frame 1. The telescopic mechanism 51 is connected to the frame 1 and is located above the support rollers 55. The telescopic mechanism 51 is provided with a rotatable clamping member 512. The pair of support rollers 55 jointly support the fabric roll, and the telescopic mechanism 51 drives the clamping member 512 to insert into the paper tube of the fabric roll to tighten and fix the paper tube.

[0035] The fabric roll can be draped over the conveying unit 2. The cutting module 3 is equipped with a liftable pressure plate 4. The pressure plate 4 is used to press the fabric onto the conveying unit 2 and cooperates with the conveying unit 2 through the longitudinal drive mechanism 23 to pull the fabric out in the longitudinal direction.

[0036] It should be noted that the camera component 12 can be a camera. The function of the camera has been disclosed in Chinese patent CN219768396U, so the function of the camera component 12 will not be explained in detail in this embodiment.

[0037] In this design, the worker first places the fabric roll onto a pair of support rollers 55. Then, by controlling the telescopic mechanism 51, the clamping member 512 is inserted into the paper core of the fabric roll to tighten and fix it. Next, a section of the fabric roll is pulled out and draped over the conveyor unit 2. Then, the camera component 12, in conjunction with the longitudinal drive mechanism 23 and the cutting module 3, cuts the fabric on the conveyor unit 2. After this section of fabric is cut, the cutting module 3 stops working, the pressure plate 4 descends and presses the fabric onto the conveyor unit 2, and then the longitudinal drive mechanism 23 drives the pressure plate 4. Moving longitudinally and cooperating with the conveying unit 2, the fabric is pulled out longitudinally, allowing the cutting module 3 to cut a new section of fabric. After the entire fabric roll is pulled out, leaving only the paper tube, the telescopic mechanism 51 drives the clamping member 512 to reset and release the paper tube. Then, the worker only needs to remove the paper tube and place the new fabric roll on a pair of support rollers 55, and then use the telescopic mechanism 51 to drive the clamping member 512 to tighten and fix the paper tube. In this way, it is convenient for workers to change fabric rolls, and the cutting module 3 can cut fabric continuously.

[0038] Preferably, the conveying unit 2 includes a fixed platform mounted on the frame 1, a belt conveyor 22 mounted on the fixed platform, and a longitudinal drive mechanism 23 mounted on the fixed platform;

[0039] It also includes a threaded rod 211, a mounting bracket 213, a first drive mechanism 215 mounted on the machine base 21, and a guide rod 212; the guide rod 212 and the threaded rod 211 are located on both sides of the belt conveyor 22, respectively.

[0040] The two ends of the mounting bracket 213 are respectively connected to the guide rod 212 and the threaded rod 211. The first driving mechanism 215 is connected to the threaded rod 211. The first driving mechanism 215 is used to drive the rotation of the threaded rod 211, thereby driving the lifting and lowering of the pressure roller 214.

[0041] In practical use, the first drive mechanism 215 can use a motor and a bevel gear to drive the threaded rod 211 to rotate, thereby realizing the lifting and lowering of the pressure roller 214.

[0042] Specifically, the worker places the fabric on the belt conveyor 22, and then drives the threaded rod 211 to rotate by controlling the first drive mechanism 215, so that the pressure roller 214 can press the fabric onto the belt conveyor 22 at the feed end of the belt conveyor 22. This can both smooth the fabric and make it easier to move the fabric longitudinally on the belt conveyor 22.

[0043] Preferably, the cutting module 3 includes a cutting component 32 and a transverse driving mechanism 31 for driving the cutting component 32 to move laterally. The transverse driving mechanism 31 is connected to the longitudinal driving mechanism 23, and the cutting component 32 is connected to the transverse driving mechanism 31.

[0044] The transverse drive mechanism 31 is equipped with a first cylinder 41, and the output end of the first cylinder 41 is connected to the pressure plate 4.

[0045] The frame 1 is equipped with a gantry frame 11, and the camera assembly 12 is located on the top of the inner wall of the gantry frame 11.

[0046] The longitudinal drive mechanism 23, the cutting component 32, the camera component 12, and the transverse drive mechanism 31 have been disclosed in Chinese patent CN219768396U, so the structure of the longitudinal drive mechanism 23, the cutting component 32, and the transverse drive mechanism 31 will not be described in detail in this embodiment.

[0047] Specifically, when it is necessary to pull out the fabric, the cutting module 3 stops operating, and the first cylinder 41 drives the pressure plate 4 to move downward to press the fabric onto the belt conveyor 22. Then, the longitudinal drive mechanism 23 drives the pressure plate 4 to move in the longitudinal direction, while the belt conveyor 22 also moves in the longitudinal direction, thereby pulling out the fabric.

[0048] More preferably, the feeding unit 5 further includes a fixed frame 52 disposed at one end of the frame 1, and the two support rollers 55 are rotatably connected to the fixed frame 52;

[0049] The telescopic mechanism 51 includes a second cylinder 511 disposed on one side of the fixed frame 52, and the clamping member 512 is rotatably connected to the output end of the second cylinder 511.

[0050] The fixed frame 52 is provided with a second drive mechanism 54 and a hollow part. Both of the two support rollers 55 are connected to the second drive mechanism 54, and both of the two support rollers 55 are located above the hollow part.

[0051] A collection box 53 is provided below the support roller 55. The second drive mechanism 54 is used to drive the two support rollers 55 to move towards each other so that the paper tube falls from the cutout 6 into the collection box 53.

[0052] The second driving mechanism 54 includes a double-ended screw 542 and a guide rod 541 spaced apart along the length of the fixed frame 52. The fixed frame 52 is also provided with a rotary motor 543 for driving the double-ended screw 542 to rotate. The output end of the rotary motor 543 is connected to one end of the double-ended screw 542.

[0053] One end of the support roller 55 is connected to a first connecting block 551, and the other end is connected to a second connecting block 552. The first connecting block 551 is connected to the guide rod 541, and the second connecting block 552 is connected to the double-ended screw 542.

[0054] Furthermore, both support rollers 55 are rotatable, which facilitates the pulling out of the fabric. After the fabric is rolled onto the two support rollers 55, the second cylinder 511 drives the clamping member 512 to insert into the paper tube of the fabric roll and tighten it. After the fabric on the roll is completely pulled out, the rotary motor 543 drives the double-headed screw 542 to rotate, causing the second connecting block 552 to move, thereby driving the support rollers 55 to move, and then causing the two support rollers 55 to move towards each other. After that, the second cylinder 511 drives the clamping member 512 to reset, releasing the fixation on the paper tube. The paper tube then falls under the action of gravity and falls into the collection box 53 for collection after passing through the perforated part.

[0055] In this embodiment, the fixing frame 52 includes a frame body 521 mounted on the frame 1 and a frame body 522 connected to the frame body 521 by a spring 523. The hollow part includes a first opening 61 mounted on the frame body 522 and a second opening 62 mounted on the frame body 521. The frame body 521 is also provided with an arc-shaped guide plate 5211. The second driving mechanism 54 is mounted on the frame body 522. The telescopic mechanism 51 is symmetrically arranged on both sides of the frame body 521.

[0056] Furthermore, by connecting the frame 522 to the bracket 521 via the spring 523, the two support rollers 55 can better support the fabric roll. After the telescopic mechanism 51 drives the clamping member 512 to release the fixing of the paper tube, the paper tube passes through the first opening 61 and the second opening 62 in sequence and falls onto the guide plate 5211. The paper tube rolls on the guide plate 5211 and is then guided into the collection box 53 through the arc-shaped guide plate 5211.

[0057] Preferably, the clamping member 512 includes a first body 5121 and a second body 5122. The first body 5121 is cylindrical and is rotatably connected to the output end of the second cylinder 511. The second body 5122 is connected to the other end of the first body 5121 and gradually contracts in a direction away from the first body 5121.

[0058] Specifically, the second body 5122 gradually contracts in a direction away from the first body 5121, making it easier to insert into the paper tube of the fabric roll and tighten and fix the fabric roll. Moreover, the first body 5121 is rotatably connected to the output end of the second cylinder 511, so that when the longitudinal drive mechanism 23 drives the pressure plate 4 to move longitudinally, the fabric roll can be pulled out.

[0059] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements or modifications can be made without departing from the principle of the present utility model, and these improvements or modifications should also be considered within the protection scope of the present utility model.
