[0029] In combination Figures 1-4 The present embodiment discloses a cutting module based on visual positioning, aiming to realize high-precision and high-efficiency cutting of wide fabric by integrating visual positioning technology, multi-axis driving system and flexible cutter 360 mounting structure.

[0030] In the present embodiment, the cutting module specifically includes a displacement device, a punching device 300 and a visual positioning device.

[0031] Among them, such as Figure 1As shown, the displacement device comprises two first slide rails 100 arranged in parallel with a left-right interval, a first sliding block 110 movably connected on the first slide rail 100, a first driving member connected with the first sliding block 110, the first driving member being capable of controlling the first sliding block 110 to reciprocate along the length direction of the first slide rail 100; a second slide rail 200 is vertically arranged above the first slide rail 100, the bottom of the second slide rail 200 is connected with the first sliding block 110 on the left and right two first slide rails 100, the first sliding block 110 is capable of driving the second slide rail 200 to reciprocate along the length direction of the first slide rail 100, a second sliding block 210 is movably connected on the second slide rail 200, a second driving member is connected with the second sliding block 210, the second driving member is capable of controlling the second sliding block 210 to reciprocate along the length direction of the second slide rail 200. In actual application, the first slide rail 100 is used to provide structural support for the front and back movement of the second slide rail 200, and the second slide rail 200 is used to provide structural support for the left and right movement of the blanking device 300, and the two are cooperated to constitute a double-shaft linkage mechanism, so that the blanking device 300 can be flexibly moved.

[0032] In order to accurately control the positions of the first sliding block 110 and the second sliding block 210, a position sensor 130 (such as a photoelectric switch or a proximity switch) is arranged. When the sliding block reaches the preset position, the position sensor 130 sends a signal to trigger the driving member to stop running, so as to ensure that the moving distance is within the safe stroke range.

[0033] Further, the first driving member and the second driving member specifically adopt a reduction motor, which are respectively a first motor 120 and a second motor 220, and a screw transmission assembly is arranged between the first motor 120 and the first sliding block 110 and between the second motor 220 and the second sliding block 210. The reduction motor has the advantages of large output torque, stable rotating speed, high control precision, etc., and can meet the accurate position control requirements of the cutting die assembly in the horizontal and vertical directions.

[0034] In order to ensure the stable sliding between the first sliding block 110 and the first slide rail 100 and between the second sliding block 210 and the second slide rail 200, a linear guide structure is arranged, and in the embodiment, guide grooves are arranged on the side walls of the first slide rail 100 and the second slide rail 200. The linear guide structure can improve the stability and precision of sliding.

[0035] The second sliding block 210 is detachably connected with a blanking device 300, which is used to complete the cutting of the label in cooperation with an external pressure structure (such as a hydraulic mechanism).

[0036] Specifically, the punching device 300 comprises a base 310, which is a U-shaped frame structure, and one end of the base 310 is connected with the second sliding block 210 through fasteners (bolts). The base 310 is provided with a rotary driving member, which is specifically a third motor 331.

The third motor 331 can accurately adjust the angle of the pressing rod 320 according to actual instructions, so as to meet the punching requirements at different angles.

[0037] Further, the pressing rod 320 is vertically arranged and can move up and down relative to the base 310. The top of the pressing rod 320 is provided with a pressing block 321 for receiving an external pressing mechanism. The bottom of the pressing block 321 is abuttingly provided with a reset spring 340 relative to the base 310. The bottom of the pressing rod 320 is provided with a detachable cutter 360. Figure 2 And Figure 4 The bottom of the pressing rod 320 is provided with a cutter seat 350. The cutter 360 is detachably arranged at the bottom of the cutter seat 350. The shape and size of the cutter seat 350 are matched with the cutter 360, so that the cutter 360 can be stably installed and transmit the pressing force. The cutting edge of the cutter 360 faces downward, which is used for cutting the fabric. The top of the cutter seat 350 is provided with a buffer structure between the base 310, which is used for reducing the impact and damage to the fabric during cutting, and improving the cutting quality. The buffer structure in the embodiment is a disc spring 370, and the extension direction of the disc spring 370 is parallel to the longitudinal direction.

[0038] In order to adapt to the cutting requirements of some special fabrics (such as thermoplastic materials), the cutter seat 350 is provided with a heating module. The heating module can heat the cutter 360 to a certain temperature, so that the cutter 360 can soften the fabric during cutting, reduce the cutting resistance, and improve the cutting efficiency and quality.

[0039] The application of the buffer structure and the heating module can reduce the impact and damage to the fabric and the cutter 360 during cutting, and improve the cutting quality and service life.

[0040] The base 310 is provided with an extension frame 380, and the visual positioning mechanism 390 is installed on the extension frame 380. The extension frame 380 is vertically arranged on the top of the base 310, and the visual positioning mechanism 390 is located on one side of the pressing rod 320, so as to facilitate real-time capture of the pattern information on the fabric. The visual positioning mechanism 390 adopts a high-precision camera and an image processing algorithm, can capture the pattern information on the fabric in real time, and accurately calculate the cutting position. Through linkage control with the driving system, high-precision cutting of complex patterns or fine lines on the fabric is realized. The application of the visual positioning mechanism 390 greatly improves the cutting precision and efficiency, and reduces the difficulty and error of manual operation. The image processing algorithm in the visual positioning mechanism 390 can identify and analyze the patterns on the fabric, and extract the feature information required for cutting. By comparing and matching with the preset cutting template, the cutting position is calculated. The image processing algorithm has the characteristics of high precision, high speed and strong robustness, and can adapt to the cutting needs of different fabrics and patterns. It should be noted that the visual positioning mechanism 390 is prior art, and its specific structure and working principle will not be described here. Those skilled in the art can select and implement it from prior art according to actual working conditions.
