[0002] With the development of automation technology, people's requirements for the shape and style of printed fabric products are becoming more and more diverse, which means that the patterns of printed fabrics that need to be cut are becoming more and more complex, and thus the automation level of the cutting machine needs to be continuously improved. The automatic cutting table is a cutting device used to automatically cut fabrics. It is widely used in the clothing manufacturing industry. It uses the data set by the cutting table computer to control the cutting path of the cutter, and then cuts out the required fabric pieces. It can cut single-layer and multi-layer printed fabrics. During the cutting process, due to the large number of printed fabric layers, it is necessary to keep the cutting path of the cutting table consistent with the printed pattern when cutting the printed fabric to ensure that the pattern of the printed fabric remains intact after cutting.

[0003] However, in the traditional multi-layer automatic cutting table industry, when cutting printed fabrics, it is necessary to rely on manual observation to see whether the printed pattern is consistent with the cutting path of the cutting table, and then set the cutting data of the cutting table computer. Due to the error of manual observation, it is inevitable that a certain error will occur between the printed pattern and the cutting path of the cutting table during the cutting process, and it cannot be corrected in real time during the cutting process. When the pattern of the printed fabric is not accurately positioned with the cutting path of the cutting table, the cutting accuracy is reduced, and the pattern on the printed fabric will be destroyed by cutting and become waste, which not only causes fabric waste but also reduces cutting efficiency.

[0006] As a further technical solution, a distance sensor is fixedly connected to one side of the fixing plate, and the distance sensor is used to monitor the height between the camera lens of the visual camera and the printed fabric in real time.

[0007] As a further technical solution, the visual camera and the distance sensor are both electrically connected to the cutting table computer.

[0010] As a further technical solution, the distance sensor is a digital distance sensor.

[0011] The beneficial effects of the utility model are as follows: the visual positioning mechanism of the utility model is connected to the moving mechanism and moves synchronously with the cutting device. The height difference between the camera lens and the printed fabric can be kept consistent through the distance sensor. The camera only needs to focus once to ensure that the image transmitted to the multi-layer automatic cutting bed computer is clear, so that the cutting bed computer can better identify the print, keep the pattern of the printed fabric consistent with the cutting path of the cutting bed, and ensure cutting accuracy.

[0018] like Figure 1 and Figure 2 As shown, the utility model is a visual positioning automatic cutting device for printed fabrics, comprising a cutting bed body 1 and a cutting bed computer 2 provided with a PLC control system located on one side of the cutting bed body 1, wherein the cutting bed body 1 is also provided with a cutting device 4 for cutting printed fabrics 8, which is controlled and moved by a moving mechanism 3. The cutting bed body 1 also includes a vacuum suction device and a film pressing component, etc. The moving mechanism 3 includes an X-axis moving component and a Y-axis moving component, and the cutting device 4 is equipped with a cutting knife. The moving mechanism 3 and the cutting device 4 jointly drive the cutting knife to complete various curve or straight line cutting on the table. The PLC control system controls the cutting path, shape and route, as well as the cutting speed, cutting tool conversion, sharpening knife spacing, the starting, temporary and termination of the moving mechanism 3 and the cutting device 4, etc. The above adopts the existing technology and will not be described in detail here.

[0019] In a preferred embodiment, the moving mechanism 3 is connected to a visual positioning mechanism 5 electrically connected to the cutting table computer 2, the visual positioning mechanism 5 moves synchronously with the cutting device 4, the visual positioning mechanism 5 is connected to a visual camera 6 and a distance sensor 7, the visual camera 6 and the distance sensor 7 are electrically connected to the cutting table computer 2, and the distance sensor 7 preferably adopts a digital distance sensor to facilitate sending the signal directly to the PLC control system of the cutting table computer 2.

[0020] By monitoring the height between the distance sensor 7 and the printed fabric 8, the visual positioning mechanism 5 can be raised and lowered, so that the height difference between the camera lens of the visual camera 6 and the printed fabric 8 can always be kept consistent. The visual camera 6 only needs to focus once to ensure that the image transmitted to the cutting table computer 2 is clear, so that the cutting table computer 2 can better identify the print. The PLC control system of the cutting table computer 2 can drive the moving mechanism 3 and the cutting knife device 4 to accurately locate the pattern of the printed fabric 8 to ensure cutting accuracy.

[0021] In a preferred embodiment, the visual positioning mechanism 5 includes a fixed plate 501 fixedly connected to the moving mechanism 3 and a servo motor 502 fixedly connected to the fixed plate 501. The fixed plate 501 includes a horizontally arranged bottom fixedly connected to the moving mechanism 3 and a vertical portion perpendicular to the bottom, and the upper end of the vertical portion is fixedly connected to a top fixedly connected to the servo motor 502. The output end of the servo motor 502 is connected to a lead screw 503, and the lead screw 503 is connected to a lead screw slider 505, and the lead screw slider 505 is slidably connected to a guide rod 504 fixedly connected to the fixed plate 501, so that the servo motor 502 can drive the lead screw slider 505 to move up and down.

[0022] The lead screw slider 505 is fixedly connected with a visual camera 6, and the distance between the visual camera 6 and the printed fabric 8 is adjusted by the visual positioning mechanism 5, so that the cutting machine computer 2 can monitor the cutting path of the printed fabric by the cutting device 4 in real time according to the visual camera 6. Therefore, according to the above-mentioned distance sensor 7, the height difference between the camera lens of the visual camera 6 and the printed fabric 8 can always be kept consistent, and the camera only needs to focus once to ensure that the image transmitted to the multi-layer automatic cutting machine computer is clear, so as to better identify the printing and ensure the cutting accuracy.

[0023] When the utility model is in use, the cutting table body 1 does the preparation work, spreads the cloth, starts the vacuum to absorb the printed fabric, checks the actions to be correct, and then starts cutting. During the cutting process, the distance sensor 7 monitors the height difference between the visual camera 6 and the printed fabric 8 in real time, and transmits a signal to the PLC control system of the cutting table computer 2 to keep the height difference between the visual camera 6 and the printed fabric 8 appropriate, thereby ensuring that the image transmitted to the cutting table computer 2 is clear until the cutting is completed.

[0024] The working principle of the utility model is as follows: after the whole device is powered on, the visual camera 6 returns to the mechanical origin 506, and the focal length of the visual camera to the printed fabric is adjusted to make the image transmitted to the display clear. The distance sensor 7 senses the height difference between the visual camera 6 and the printed fabric 8 in real time, and transmits a signal to the PLC control system of the cutting table computer 2.
