[0034] The lateral side wall of the longitudinal axis swing angle adjustment seat 31 is fixedly connected with a swing angle adjustment motor 33, and the motor shaft of the swing angle adjustment motor 33 is coaxially fixedly connected with the worm 324. The top wall of the longitudinal axis swing angle adjustment block 32 is fixedly connected with a laser 4, and the front end of the laser 4 is fixedly connected with a laser head 41.
[0035] Specifically, two guide rods 14 are fixedly connected in the column 1, the column 1 is provided with a slot 15, and the vertical slide 11 is provided with a vertical plate 111, which is slidably matched with the slot 15.

[0043] Specifically, see Figure 2 Two vertical recognition cameras 412 are provided on the front side of the bottom wall of the laser head 41 , and two oblique recognition cameras 113 are provided on the front side of the top wall of the vertical slide 11 .
[0044] The working principle of this utility model laser pattern machine is as follows:
[0045] Combination Figure 1 , Figure 2 , Figure 5 After placing the sportswear (or yoga wear) on the steel plate 5, the focus dial 13 drives the lead screw to rotate, thereby driving the laser head 41 to slide vertically to a suitable position to achieve the initial focus of the laser head 41. Figure 7 The status is shown in the left middle.
[0046] During the initial focusing process, the vertical recognition camera 412 and the oblique recognition camera 113 respectively shoot the sportswear (or yoga wear) from the vertical and oblique directions, thereby collaboratively calculating and recognizing the thickness of the sportswear (or yoga wear). According to the recognized thickness of the sportswear (or yoga wear), the transverse driving module 2 drives the transverse slider 21 to move to a suitable position, and at the same time, the swing angle adjustment motor 33 drives the worm 324 to rotate (see Figure 3 ), thereby driving the longitudinal axis swing angle adjustment block 32 to swing to a suitable angle, such as Figure 7 During the swinging process of the longitudinal swing angle adjustment block 32, the laser head 41 will perform self-fine adjustment of the focal length accordingly, so that the laser focal length is adapted to the swinging angle.
[0047] At this time, the angle between the laser light emitting path of the laser head 41 and the vertical direction is θ. Therefore, when the laser is irradiated to the surface of the yoga clothes (fitness clothes), part of the light will be reflected and will not be completely concentrated at the irradiation point, thereby reducing the energy concentration at the irradiation point, thereby avoiding damage to the clothing fibers at the marking location of the yoga clothes (fitness clothes), thereby avoiding easy tearing at the marking location.
[0048] See Figure 3 , Figure 4 Since the arc-shaped protrusion 312 is slidably connected to the arc-shaped groove 321, the longitudinal axis swing angle adjustment block 32 will not separate from the longitudinal axis swing angle adjustment seat 31 during the swinging process of the longitudinal axis swing angle adjustment block 32.
[0049] See Figure 5 The two rollers 112 on the same side abut against the sliding pair structure on the inner side of the guide rod 14 on the same side, which can improve the stability of the vertical slide 11 moving up and down, so that the vertical slide 11 always remains horizontal without deviation.
[0050] The above are only preferred embodiments of the present invention, and are not intended to limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
