The pressing force of the cylinder on the LCD screen is also not easy to control. Excessive pressing force can also cause the LCD screen to deform or even break. For this reason, the present application proposes an LCD screen cutting device. Utility Model Content

DETAILED DESCRIPTION

[0020] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0021] like Figure 1-Figure 3 As shown, the embodiment of the utility model provides an LCD screen cutting device, comprising:

[0022] The box body 1 is movably connected with a box door 2, the box door 2 is rotatably connected to the box body 1 through a hinge, and a door lock is provided between the box door 2 and the box body 1;

[0023] A water cutter 7 capable of three-dimensional movement is installed in the box 1. To further explain, an X-axis moving mechanism 3, a Y-axis moving mechanism 4 and a Z-axis moving mechanism 5 are installed in the box 1. The Y-axis moving mechanism 4 is installed on the moving end of the X-axis moving mechanism 3, and the Z-axis moving mechanism 5 is installed on the moving end of the Y-axis moving mechanism 4. The X-axis moving mechanism 3 and the Y-axis moving mechanism 4 are both electric slide rails and electric sliders, and the electric slider moves on the electric slide rails. The Y-axis moving mechanism 4 is installed on the electric slider on the X-axis moving mechanism 3. The Z-axis moving mechanism 5 is an electric push rod, and the Z-axis moving mechanism 5 is installed on the electric slider on the Y-axis moving mechanism 4. The water cutter 7 is installed on the output end of the Z-axis moving mechanism 5. The above are all prior arts, wherein the water cutter 7 is located in the box 1 as a hose, which is supplied with water by an external high-pressure pump;

[0024] A support platform 10 is provided with a circular groove 6 at the upper end of the support platform 10, and a connecting tube 15 is slidably connected in the circular groove 6. The connecting tube 15 is positioned by a locking mechanism installed on the support platform 10. The locking mechanism includes a locking pin 13 that penetrates the support platform 10 and extends into the circular groove 6 and is slidably arranged between the support platform 10. A spring 14 is fixed between the locking pin 13 and the support platform 10. A pin groove 16 is provided on the connecting tube 15, and the locking pin 13 is slidably connected in the pin groove 16. The locking pin 13 is manually pulled out of the pin groove 16. At this time, the connecting tube 15 is no longer limited, and the connecting tube 15 can be removed by moving it upward; similarly, during installation, the locking pin 13 is also pulled so that it is not in the circular groove 6 to avoid the locking pin 13 blocking the connecting tube 15; wherein, the bottom of the connecting tube 15 is sealed and connected to the circular groove 6 by a rubber ring;

[0025] A hollow plate 11 connected to the hollow plate 11 is fixed at the upper end of the connecting tube 15. Since the connecting tube 15 can be disassembled, the hollow plate 11 can be disassembled; a plurality of negative pressure holes 12 are provided at the upper end of the hollow plate 11, and a first vacuum pump 8 connected to the circular groove 6 on the support platform 10 is installed on the box body 1. The first vacuum pump 8 can generate negative pressure at the negative pressure hole 12 when it works, so that the display screen can be adsorbed and fixed on the hollow plate 11 (the display screen and the upper end of the hollow plate 11 are against each other), the adsorption positioning of the display screen is more stable, the force on the display screen is more uniform and it is not easy to cause the display screen to deform, wherein the size of the hollow plate 11 is the same as the size of the required display screen after cutting, that is, the water cutter 7 only needs to cut according to the boundary of the hollow plate 11 to obtain the required display screen, so that the hollow plate 11 can not only stably adsorb the display screen but also stably support it, and at the same time, the water cutter 7 will not cause damage to the hollow plate 11 when cutting the display screen, because there is a certain height between the hollow plate 11 and the box body 1, and the box body 1 will not be damaged;

[0026] Since the hollow plate 11 is detachable, the corresponding hollow plate 11 can be replaced for different display screens to meet the use requirements;

[0027] The second vacuum pump 9 is also included. The second vacuum pump 9 is installed on the box body 1 and is used to evacuate the interior of the box body 1. The box body 1 can be evacuated by the second vacuum pump 9.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
