[0016] The present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0017] like Figure 1 As shown, the utility model is a light guide plate processing equipment for cutting semi-finished light guide plates, which includes a frame 1 and a cutting mechanism 2.

Limiting plates 61 are provided on the three adjacent side edges of the frame 1, and one side is left as a feed port 62. One side of the feed port 62 can cooperate with the conveyor belt for automatic loading. The cutting device is slidably connected to the guide rail through a pulley. The two guide rails are arranged along the length direction of the cutting table 6 and are located on the outside of two of the limiting plates 61. A plurality of vacuum suction nozzles 7 are provided on the upper end surface of the cutting table 6. The vacuum suction nozzle 7 is horizontal with the upper end surface of the cutting table 6. A vacuum source is provided on the frame 1 below the cutting table 6. A plurality of vacuum tubes are separated from the vacuum source, which are respectively connected to the vacuum suction nozzle 7. A plurality of photoelectric sensors 8 are also provided on the cutting table 6. The photoelectric sensor 8 is used to detect the position of the cutting mechanism 2.

[0018] like Figure 1 As shown, the cutting mechanism 2 has a linear module 4, a cutting head 5 is provided on the linear module 4, and a supporting block 3 is provided at each end of the linear module 4. A pulley is provided on the lower side of the supporting block 3 facing the linear module 4. When in use, the pulley is placed in the guide rail and slidably connected thereto, and the position of the linear module 4 on the supporting block 3 is higher than the height of the limit plate 61. A driving cavity is opened in one of the supporting blocks 3, and a progressive motor is installed in the driving cavity. The output shaft of the progressive motor extends out of the driving cavity and is connected to the pulley near it. The progressive motor drives a slide The pulley moves, and when the pulley moves, it drives the other pulley relative to it to move synchronously through the connected linear module 4, so that the cutting mechanism 2 moves along the X-axis direction; the cutting head 5 is fixed to the upper end of the linear module 4, and the linear module 4 spans the cutting table 6 above the cutting table 6. The linear module 4 drives the cutting head 5 to move along the Y-axis direction. In summary, the cutting head 5, under the action of the guide rail and the linear module 4, can be moved to any position on the cutting table 6, so as to realize the cutting of semi-finished light guide plates of different sizes, thereby improving the application range and convenience of the equipment.

[0019] like Figure 2As shown, the cutting head 5 has a housing, and a plurality of mutually cooperating mounting plates are provided in the housing. Specifically, the mounting plates include a first mounting plate 51 for mounting a driving assembly, a second mounting plate 52 provided between the transmission assembly and the tool, and a third mounting plate 53 fixed to one side of the first mounting plate 51 and used to fix the distance measuring assembly. The driving assembly adopts a servo motor 54, and the transmission assembly consists of a driving wheel 55, a driven wheel 56 and a transmission belt 57 wound around the two wheels. The output shaft of the servo motor 54 passes downward through the first mounting plate 51 and is connected to the driving wheel 55. The driven wheel 56 is mounted on the upper end surface of the second mounting plate 52. The driving wheel 55 drives the driven wheel 56 through the transmission belt 57. 6 synchronous movement, the tool is set on the lower end surface of the second mounting plate 52, and the tool consists of a transmission shaft 59, a protective shell 58 and a cutter head 11.

The transmission shaft 59 extends upward to pass through the driven wheel 56 and the first mounting plate 51 respectively, and extends upward from the upper end surface of the first mounting plate 51. The extended part is connected to the adjusting cylinder 10. There is an elastic pressing piece between the adjusting cylinder 10 and the transmission shaft 59. When the adjusting cylinder 10 requires the transmission shaft 59 to descend, the piston rod of the adjusting cylinder 10 extends downward and squeezes the elastic pressing piece, so that the transmission shaft 59 connected thereto moves downward synchronously.

[0020] like Figure 1 、 Figure 2 As shown, when in use, the semi-finished light guide plate is placed on the cutting table 6, and the cutting mechanism 2 moves along the guide rail from the side of the frame 1 to the cutting table 6. At this time, the height of the cutter head 11 is far away from the semi-finished light guide plate. When it moves to the first photoelectric sensor 8 of the cutting table 6, it stops moving. At this time, the laser rangefinder 9 as a distance measuring component is used to position the cutting head 5 and measure the distance between the cutter head 11 and the semi-finished light guide plate. Subsequently, pressure is applied to the drive shaft 59 by adjusting the cylinder 10, forcing the drive shaft 59 to move downward until the cutter head 11 can penetrate the semi-finished light guide plate. The servo motor 54 starts and synchronously drives the driving wheel 55 to rotate. The driving wheel 55 synchronously drives the driven wheel 56 to move through the transmission belt 57, and the driven wheel 56 drives the transmission shaft 59 to move, thereby causing the cutter head 11 connected to the transmission shaft 59 to rotate. By adjusting the position of the cutting head 5, the semi-finished light guide plate is cut into finished light guide plates of appropriate size.
