[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Reference Figure 1 、 Figure 3 and Figure 4 , the utility model provides an embodiment: an FPC board laser cutting jig, including a shell 1, a protective door and an observation window are provided on the front side to provide external protection for the entire jig, and prevent external environmental factors from interfering with internal equipment and ongoing cutting operations. A cutting machine 2 is provided on the inner wall of the shell 1, which is used to perform laser cutting operations on the FPC board placed on the placement plate 3. This technology is existing technology, so it is not described in detail. A placement plate 3 is provided on the inner wall of the shell 1 near the bottom of the cutting machine 2 to provide a stable placement platform for the FPC board, and the FPC board is limited by a fixing mechanism. A fixing mechanism is provided on the inner wall of the shell 1, and the fixing mechanism includes a moving component and a clamping component. The moving component is provided on the inner wall of the shell 1 near the periphery of the placement plate 3 to drive the clamping component to move.

[0032] Furthermore, the clamping assembly includes a moving part 51, which can slide in the slide groove 44, so as to adjust the position of the clamping assembly in the horizontal direction to adapt to FPC boards of different sizes, and provide support for the fixed column 52. The moving part 51 is arranged on the moving assembly, and the right side of the moving part 51 is fixedly connected to the fixed column 52, which provides an installation position for the limit column 53, the compression spring 54 and the gasket 55. The inner wall of the fixed column 52 is slidably connected to the limit column 53. Under the action of the compression spring 54, pressure is applied downward to the FPC board to achieve clamping and fixing of the FPC board. The right side of the limit column 53 is set as a column, and the bottom end of the column on the right side of the limit column 53 is set as a rubber material, which can increase the friction between the FPC board and the FPC board, improve the stability of the clamping and avoid In order to avoid damage to the FPC board, a gasket 55 is provided on the upper side of the limiting column 53, and the gasket 55 is elastically connected to the fixed column 52 through a compression spring 54. One end of the compression spring 54 is fixedly connected to the inner wall of the fixed column 52, and the other end of the compression spring 54 is fixedly connected to the upper side of the gasket 55, connecting the gasket 55 and the inner wall of the fixed column 52, providing downward elastic pressure for the limiting column 53, so that the limiting column 53 can be tightly pressed on the FPC board to ensure that the FPC board will not loosen during the cutting process. At the same time, the reverse action force of the compression spring 54 is used to squeeze the moving part 51 and the slide groove 44, thereby frictionally limiting the moving part 51, and at the same time, the fixed rod 43 drives the slider 42 to squeeze the outer side of the guide rail 41, thereby stabilizing the fixed rod 43 and the slider 42.

[0033] Reference Figure 2 and Figure 3 The moving component includes a guide rail 41, which provides a stable moving track for the slider 42 to ensure that the slider 42 can move smoothly. The guide rail 41 is fixedly connected to the inner wall of the shell 1. The slider 42 is slidably connected to the outside of the guide rail 41, and cooperates with the guide rail 41 to slide on the guide rail 41. By connecting with the fixed rod 43, the fixed rod 43 and the clamping component installed on the fixed rod 43 are driven to move, so that the clamping position can be adjusted according to FPC boards of different sizes. The upper side of the slider 42 is fixedly connected to the fixed rod 43 as the mounting carrier of the clamping component, connecting the slider 42, and transmitting the movement of the slider 42 to the clamping component. There are multiple groups of guide rails 41 and sliders 42. Every two groups of guide rails 41 and sliders 42 are symmetrically arranged with the center line of the fixed rod 43 as the symmetry axis. Two groups of fixed rods 43 are provided, which improves the stability of the fixed rod 43.

[0034] Reference Figure 3 and Figure 4The inner wall of the fixed rod 43 is horizontally penetrated with a slide groove 44 to limit the moving direction of the movable member 51, so that the movable member 51 can slide horizontally on the fixed rod 43, so that the clamping point can be flexibly adjusted according to the different positions of the FPC board. The movable member 51 is slidably connected to the inner wall of the slide groove 44, and the clamping assembly is provided with multiple groups. The multiple groups of clamping assemblies are evenly arranged on the inner walls of the two groups of fixed rods 43, which can increase the clamping points of the FPC board and improve the clamping stability of the FPC board. A limiting assembly is provided on the outer side of the fixed column 52, and the limiting assembly includes a card slot 6 for limiting the limiting column 53. The limiting column 53 after being limited in sequence can be quickly moved out from above the placement plate 3, and at the same time effectively prevents the column part of the limiting column 53 from rubbing against the placement plate 3. The card slot 6 is opened on the rear side of the fixed column 52, and the limiting column 53 slides on the inner wall of the fixed column 52.

[0035] Working principle: During use, when the FPC board needs to be laser cut, the FPC board is placed on the placement plate 3. At this time, the fixing rod 43 is pulled to move, driving the slider 42 to slide on the guide rail 41, and adjusting the position of the clamping assembly in the horizontal direction to adapt to FPC boards of different sizes.

[0036] At this time, according to the specifications of the FPC board, the movable part 51 is slid on the inner wall of the slide groove 44, so that the right column of the limiting column 53 inserted in the card slot 6 is aligned with the edge of the FPC board, and the limiting column 53 is moved. Under the action of the compression spring 54, the limiting column 53 applies pressure downward to the FPC board to achieve clamping and fixing of the FPC board.

[0037] At the same time, the reverse force of the compression spring 54 causes the moving part 51 and the slide groove 44 to squeeze each other, thereby frictionally limiting the moving part 51. At the same time, the fixed rod 43 drives the slider 42 to squeeze the outer side of the guide rail 41, stabilizing the fixed rod 43 and the slider 42 to prevent sliding.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
