[0021] To make the above-mentioned objectives, features, and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments. This will enable a full understanding of how the present invention applies technical means to solve technical problems and achieve technical effects, and to implement the invention accordingly.

[0022] Due to the technical problems of low light conductivity, poor light transmittance, low transmittance and poor viewing angle brightness of the light guide plate materials in the existing technology, Figure 1 - Figure 5The utility model provides a double-sided hot-pressing PC film device, which can improve the light guiding property of the PC film light guide plate through double-sided hot pressing, improve the light transmittance, increase the transmittance and increase the viewing angle brightness. The device includes an electric control cabinet 1 and a PC film installed on the rotating shaft at the side end of the electric control cabinet 1. A feeding table 2 for moving the PC film horizontally is provided on the side of the electric control cabinet 1. Several hot pressing mechanisms 3 for hot pressing the PC film on both sides are provided on the side of the electric control cabinet 1. Several clamping tables 4 for laminating the PC film are provided on the side of the electric control cabinet 1. A circular cutting mold 5 for cutting the PC film is provided at the front of the side of the electric control cabinet 1. A main control console 6 is provided on the top of the electric control cabinet 1. The hot pressing mechanism 3 includes several hot pressing rotating shafts 3 pressed on the upper and lower surfaces of the PC film. 1. The left and right ends of the hot pressing shaft 31 are slidably connected with a plurality of fan-shaped magnets 32 for making the pressing force of the hot pressing shaft 31 more uniform. The left and right ends of the hot pressing shaft 31 are rotatably connected with a hot pressing auxiliary plate 33. The outside of the hot pressing auxiliary plate 33 is fixedly connected with a bracket plate 34. The top of the bracket plate 34 close to the electric control cabinet 1 is fixedly connected with a thermostat 35 for controlling the pressing temperature of the PC film. The side end of the thermostat 35 is fixedly connected with a temperature sensor 36 for detecting the temperature of the PC film. The side end of the thermostat 35 is fixedly connected with a number of warning lights 37. The left and right ends of the hot pressing shaft 31 are provided with a plurality of sliding cylinders for installing and removing the fan-shaped magnets 32. The side end of the hot pressing shaft 31 close to the electric control cabinet 1 is fixedly connected to the rotating end of the motor inside the electric control cabinet 1.

[0023] The utility model fixes the PC film and the coating material by the rotating shaft at the side end of the electric control cabinet 1, and uses the active control table 6 to set the electric control cabinet 1, such as the parameters such as the speed and time. After the setting is completed, the electric control cabinet 1 is started, and the device drives the PC film to move forward by the rotation of the feeding table 2. While moving, the correction device on the side of the electric control cabinet 1 will detect whether the PC film is in a straight line moving state during the hot pressing process. The PC film first enters the first hot pressing mechanism 3 to perform hot pressing on the front side. During the hot pressing process, due to the loss of long-term hot pressing and the influence of vibration generated by the electric control cabinet 1 when working, the hot pressing pressure becomes less and less. The hot pressing quality is not uniform, which causes the hot pressing quality to decline. The utility model cooperates with the hot pressing shaft 31 and the sector magnet 32. The magnetic force of the sector magnets 32 on both sides of the hot pressing shaft 31 can not only complete the hot pressing quickly, but also make the hot pressing pressure uniform with the assistance of the magnetic force, thereby improving the quality of the hot pressing. The sector magnets 32 can be disassembled and replaced regularly. In this embodiment, the number of sector magnets 32 is 8. During the replacement, several sector magnets 32 and non-magnetic sector blocks can be spaced apart. The spacing distance is the same as the distance between adjacent light guide points. In this way, more pressure can be obtained when hot pressing the light guide points.

[0024] During the rotation process, the support plate 34 and the hot pressing auxiliary plate 33 enable the hot pressing shaft 31 to smoothly complete the rotation and hot pressing. The temperature during the hot pressing process is detected and adjusted by the temperature controller 35 and the temperature sensor 36. When a problem occurs with the equipment, the warning light 37 is used to remind the staff to solve the equipment problem in time. After the hot pressing is completed, the first mold clamping table 4 is used to laminate the front side of the PC film. In this process, the second hot pressing mechanism 3 is then used to hot press the back side of the PC film, and the second mold clamping table 4 is used to laminate the back side. Finally, the cutting and forming of the PC film is completed by the circular cutting mold 5. The utility model can not only hot press the front and back sides of the PC film at the same time through the action of the hot pressing mechanism 3, but also make the pressure of the double-sided hot pressing uniform through the action of the fan-shaped magnet 32, thereby avoiding the situation where the hot pressing shaft 31 is subjected to uneven force during the hot pressing process, which affects the hot pressing effect of the PC film. The double-sided hot pressing improves the light guiding property of the PC film light guide plate, improves the light transmittance, improves the transmittance and increases the viewing angle brightness.

[0025] Due to the technical problems of low light conductivity, poor light transmittance, low transmittance and poor viewing angle brightness of the light guide plate materials in the existing technology, Figure 1 - Figure 5 The utility model provides a double-sided hot pressing PC film device, which can improve the light guiding property of the PC film light guide plate through double-sided hot pressing, improve the light transmittance, increase the transmittance and increase the viewing angle brightness. The device includes a plurality of rotating shafts arranged on the top side of an electric control cabinet 1, a correction device arranged on the rear side of a feeding table 2, a platform for installing a feeding table 2, a hot pressing mechanism 3, a clamping table 4 and a circular cutting mold 5 is arranged on the side wall of the electric control cabinet 1, and a plurality of motors for providing rotational power for the rotating shaft are arranged inside the electric control cabinet 1. The hot pressing mechanism 3 is arranged in front of the feeding table 2, and the hot pressing mechanism 3 and the clamping table 4 are staggered. The active table 6 and the electric control cabinet 1 are electrically connected.

[0026] The platform on the side wall of the electric control cabinet 1 in the present invention can have enough space to place multiple feeding tables 2, hot pressing mechanisms 3, mold clamping tables 4 and circular cutting molds 5. In this embodiment, a combination of a feeding table 2, two groups of hot pressing mechanisms 3 and mold clamping tables 4 and a circular cutting mold 5 is provided. The motor inside the electric control cabinet 1 can drive multiple shafts to rotate, including a hot pressing shaft 31, a circular cutting shaft 51 and an upper shaft 52. The PC film is first hot pressed by the first hot pressing mechanism 3, so the front of the feeding table 2 is the hot pressing mechanism 3, and then the film is coated by the first mold clamping table 4 to complete the hot pressing and peritoneum on the front side, and the hot pressing and peritoneum on the back side are completed by the second group of hot pressing mechanisms 3 and mold clamping tables 4. The active control table 6 can control the operation of the electric control cabinet 1 and can display the parameters of the electric control cabinet 1 during the working process, such as working time, number of shaft rotations, actual voltage parameters, etc.

[0027] Reference Figure 4 and Figure 5 The utility model provides a double-sided hot pressing PC film device, which can improve the light guiding property of the PC film light guide plate and improve the light transmittance through double-sided hot pressing. At the same time, the PC film light guide plate can be quickly cut by using a circular cutting mold to complete the production of the PC film light guide plate. The device includes a circular cutting shaft 51 pressed on the top surface of the PC film and an upper rotating shaft 52 slidably connected to the bottom surface of the PC film. The left and right sides of the circular cutting shaft 51 and the upper rotating shaft 52 are rotatably connected to circular cutting side plates 53. The outer side of the circular cutting side plate 53 is fixedly connected to a circular cutting bracket 54.

[0028] The utility model clamps the raised PC film light guide plate through the circular cutting shaft 51 and the upper rotating shaft 52, and uses the cutting knife 55 to perform predetermined cutting on the PC film light guide plate. The staff can replace the cutting knife 55 of different shapes according to the preset shape, and assist the circular cutting side plate 53 and the circular cutting bracket 54 to rotate the circular cutting shaft 51 and the upper rotating shaft 52. Through the action of the circular cutting mold, the cutting shape of the PC film light guide plate can be preset, and the shape of the PC film light guide plate can be quickly cut after the hot pressing is completed, which greatly improves the production efficiency of the PC film light guide plate and shortens the production time. At the same time, the disassembly of the circular cutting mold increases the flexibility of the cutting shape.
