[0031] When the light guide plate is cut by the cutting equipment, the light guide plate is first placed on the cutting table 2, and the light guide plate spans above the cutting groove 3. On the premise that a cutting mark is marked on the light guide plate, the light of the laser light strip 4 is then mapped to the cutting mark of the light guide plate, and the laser light strip 4 is arranged to be aligned up and down with the cutting wheel of the electric cutter 10. The laser light strip 4 maps the light to the position to be cut at the mark of the light guide plate, thereby facilitating the rapid and accurate determination of the position to be cut of the light guide plate, and facilitating the accurate cutting of the light guide plate by the electric cutter 10, saving the time for adjusting the cutting position of the light guide plate, and effectively improving the cutting efficiency.

[0032] like Figure 3-6 As shown, in this embodiment, a negative pressure pump 5 is fixed at the bottom end of the frame 1, and the air inlet of the negative pressure pump 5 is connected with two negative pressure pipes 6. Negative pressure adsorption chambers 7 are opened at the left and right ends of the inside of the cutting table 2, and the negative pressure pipes 6 are connected with the negative pressure adsorption chamber 7 on the same side. A plurality of negative pressure adsorption holes 8 communicating with the negative pressure adsorption chamber 7 are opened at the upper end of the cutting table 2. A mounting plate 12 is fixed at the upper end of the electric cutter 10, and the protective cover 9 slides through the mounting plate 12, and a return pressure plate 1 is fixed at the lower end of the protective cover 9. 1, at least two return springs 13 are connected between the return-type pressure plate 11 and the mounting plate 12, and a plurality of pressure rollers 14 are rotatably connected to both sides of the lower end of the return-type pressure plate 11, and a return-type sponge pad 15 connected to the lower end of the return-type pressure plate 11 is arranged between the pressure rollers 14 on the left and right sides, and an electric cylinder 25 is fixed to the lower end of the sliding block 21, and the power end of the electric cylinder 25 is connected to the upper end of the mounting plate 12, and the distance between the return-type sponge pad 15 and the cutting table 2 is smaller than the distance between the pressure roller 14 and the cutting table 2.

[0033] After the light guide plate determines the cutting position, the negative pressure pump 5 is started, and then negative pressure is generated in the negative pressure adsorption hole 8 through the negative pressure tube 6 and the negative pressure adsorption chamber 7. Then, the light guide plate can be stably adsorbed and fixed on the cutting table 2 through the negative pressure to prevent the light guide plate from shifting before cutting. In addition, the operation of the cylinder electric cylinder 25 drives the mounting plate 12, the return spring 13, the protective cover 9, the return pressure plate 11, the pressure roller 14, the return sponge pad 15 and the electric cutter 10 to move downward. First, the return sponge pad 15 will be pressed on the knife plate. After the return sponge pad 15 is deformed by pressure, Then the pressure roller 14 at the lower end of the pressure plate will press on the light guide plate, and the mounting plate 12 will continue to drive the electric cutter 10 to move downward to compress the return spring 13, so that the electric cutter 10 moves downward out of the protective cover 9 and the return pressure plate 11. Before the electric cutter 10 is powered on, the electric cutter 10 will cut the light guide plate. Since the light guide plate is fixed by negative pressure adsorption and elastically pressed by the pressure roller 14, it is beneficial to better ensure the stability of the light guide plate during cutting, avoid position deviation of the light guide plate during cutting, and effectively ensure the cutting quality.

[0035] When the knife plate needs to be moved back and forth for cutting, the forward and reverse motor 22 drives the screw rod 23 to work, and the screw rod 23 drives the sliding block 21 to move back and forth along the guide shaft 24, and then the sliding block 21 drives the electric cylinder 25, the mounting plate 12, the electric cutter 10, the protective cover 9, the return pressure plate 11, the pressure roller 14 and the return sponge pad 15 to move back and forth together, the pressure roller 14 will roll back and forth along the knife plate, and the return sponge pad 15 will sweep the surface of the light guide plate, so as to clean the dust adhering to the light guide plate, so as to conveniently drive the electric cutter 10 to move back and forth and cut the light guide plate.
