Technical Field

[0001] The present invention relates to the field of cutting equipment, and in particular to a laser cloth cutting equipment with panoramic vision and a cloth cutting method using the same. Background Art

[0002] When using a laser lace machine to process fabric, since the fabric is relatively soft, it is difficult to use ordinary fixtures to achieve workpiece positioning. Therefore, a panoramic camera is generally required to assist in positioning the fabric.

[0003] In the processing of conventional laser lace machines, most of them will manually import the vector diagram of the corresponding workpiece, and then use the computer to plan the path for processing.

[0004] However, during processing, even on different fabrics of the same size, different pairs of lace are often set. Similarly, even on the same piece of fabric, the same lace often has different sizes. Not to mention that in the processing of fabrics of various sizes and types, due to the large number of required patterns, not only does it take a lot of time to make the drawings, but it is often necessary to switch the drawings back and forth during processing, which is time-consuming and labor-intensive, and the processing efficiency is low. Summary of the invention

[0005] To solve the above problems, the present invention provides a laser cloth cutting device with panoramic vision, which directly generates a processing path through a computer by cooperating with panoramic vision shooting, thereby reducing the time for making drawings, avoiding the problem of switching drawings back and forth for fabrics of different sizes, and avoiding the situation where the drawing size and the actual workpiece size have different sizes, resulting in poor processing effects.

[0024] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0025] like Figure 1-2 As shown, the device includes a processing table 1, which is roughly square, and a recessed processing groove 2 is arranged on the table surface of the processing table 1. The processing groove 2 runs through one side of the processing table 1 (called the front side, the opposite side is called the back side, and the other two sides are called the left and right sides).

[0026] Preferably, a plurality of supporting feet 6 are respectively provided at the bottom of each corner of the processing table 1 .

[0027] Two slide grooves 7 of the same height and extending forward and backward are respectively arranged on the inner side walls on the left and right sides of the processing groove 2 (only one of them is shown in the figure), and the two ends of a screw rod 3 extending left and right are slidably installed on the two slide grooves 7, so that the screw rod 3 can slide forward and backward (the power equipment is not shown).

[0028] A laser galvanometer head 4 is movably mounted on the screw rod 3, and the laser galvanometer head 4 faces the bottom surface of the processing groove 2. The laser galvanometer head 4 can move left and right along the operation of the screw rod 3, and can move in the XY axial direction in conjunction with the forward and backward sliding of the screw rod 3, so as to process the cloth set below.

[0029] Two vertical support rods 8 are respectively arranged on the left and right sides of the table top of the processing table 1. The tops of the two support rods 8 are connected by a connecting rod 9 extending left and right, and a panoramic camera 5 is installed in the middle of the connecting rod 9. The shooting direction of the panoramic camera 5 is facing downward, so that the condition of the table top of the processing table 1 can be photographed.

[0030] In addition, a light source 10 is installed below the middle of the connecting rod 9 . The light source 10 is located below the panoramic camera 5 and can provide suitable lighting conditions for the operation of the panoramic camera 5 .

[0031] like Figure 3 As shown, when the equipment is used to cut cloth, the following processes are mainly included:

[0032] First, the cloth to be processed is loaded in the form of a roll, and the cloth is spread out and laid flat on the processing table 1, and passes through the processing tank 2 at the same time.

[0033] Then, a fixed template of lace is imported into the computer, and a panoramic camera 5 is used to photograph the fabric on the processing table 1 to obtain the fabric size and lace shape. A computer is used to generate a corresponding processing path for the lace (including alienated lace) on it and represent it with a closed vector diagram.

[0034] Then, the processing is started, and the laser galvanometer head 4 moves axially in XY direction to cut the fabric to form the required lace shape.

[0035] Then, after the processing is completed, the laser galvanometer lens 4 stops working and moves to a set safe position.

[0036] Finally, remove the cut fabric.

[0037] The present invention provides a laser cloth cutting device with panoramic vision, which mainly has the following beneficial effects:

[0038] 1. The closed vector image is generated by directly photographing the workpiece with the panoramic camera 5, and the fixed template of the lace is imported to directly generate the lace patterns of different sizes required for processing, that is, the processing path is directly generated by the computer in conjunction with the panoramic visual shooting, and the efficiency of generating the pattern is high;

[0039] 2. It can realize processing of incoming materials, reducing the time of making drawings;

[0040] 3. It avoids the problem of switching drawings of fabrics of different sizes, and realizes the needs of small quantities and diversity in actual processing;

[0041] 4. Avoid the situation where the difference between the drawing size and the actual workpiece size causes poor processing effect;

[0042] 5. The length, width, starting point coordinates and rotation angle of the template can be set to facilitate quick modification of the drawing.

[0043] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the creative concept of the present invention, which all belong to the protection scope of the present invention.
