Embodiment 1

[0024] A new type of light guide film production equipment, including a frame body, an embossing mechanism 2, a tension mechanism 3 and a hot air mechanism 4, and the frame body includes a bottom plate 101, a table top 102, an unwinding roller 103 and a winding roller and a winding roller 104 The table top 102 is affixed to the bottom plate 101 through the legs 105 provided at the four corners of its lower surface, the first support plate 106 is fixed symmetrically on the left side of the upper surface of the table top 102, and the first support plate 106 is fixed symmetrically on the right side of the upper surface of the table top 102. The second support plate 107, the unwinding roller 103 is rotatably connected between the tops of the first support plate 106, and the winding roller winding roller 104 is rotatably connected between the tops of the second support plate 107 through a first rotating shaft , the rear end of the first rotating shaft extends out of the second suppo...

Embodiment 2

[0026] The difference from Example 1 is that it also includes the following:

[0027] The embossing mechanism 2 includes an embossing frame 201 and an embossing roller 202. The embossing frame 201 is a cuboid cavity structure with an open bottom. The embossing frame 201 is fixed on the center of the upper surface of the table 102. The two sides of the embossing frame 201 are symmetrical. A groove is provided, and a guide roller 203 is rotatably connected in the groove. Seat plates 204 are symmetrically fixed on both sides of the embossing frame 201. The embossing roller 202 is rotatably connected between the seat plates 204 through the second rotating shaft. The seat plate 204 There are also through holes 205 densely distributed on the top plates of the embossing frames 201 on both sides. The rear end of the second rotating shaft protrudes out of the seat plate 204 and is fixedly connected with a driven wheel 206. The driven wheel 206 and the driving wheel 108 are linked by a b...

Embodiment 3

[0029] The difference from Example 2 is that it also includes the following:

[0030] The tensioning mechanism 3 includes a gantry frame 301, a lifting plate 302 and a tension roller 303. The gantry frame 301 is fixedly connected to the table top 102. The two vertical plates of the gantry frame 301 are evenly provided with guide grooves 304, and the two sides of the lifting plate 302 are symmetrical. A guide block 305 is fixedly connected, and the lifting plate 302 is slidingly connected with the gantry frame 301 through the cooperation of the guide block 305 and the guide groove 304, and a spring 306 is evenly fixed between the upper surface of the lifting plate 302 and the lower surface of the horizontal plate of the gantry frame 301 , the lower surface of the lifting plate 302 is symmetrically fixed with ear plates 307 , and the tension roller 303 is rotatably connected between the ear plates 307 .

[0031] Preferably, when the guide block 305 is located at the bottom of th...

Abstract

The invention discloses novel light guide film production equipment. The novel light guide film production equipment comprises a frame body, a coining mechanism, tensioning mechanisms and a hot-blastair mechanism. The frame body comprises a base plate, a table top, an unwinding roller and a winding roller. The coining mechanism is arranged in the center of the upper surface of the table top. Thetensioning mechanisms are symmetrically arranged on the table top and further located on the two sides of the coining mechanism. The hot-blast air mechanism is arranged on the frame body. The novel light guide film production equipment has the beneficial effects of being novel in structure and practical in function. Hot-blast air produced by the hot-blast air mechanism can heat and soften a lightguide film when a coining roller conducts printing on the light guide film, so that soft pressing is conducted, and breaking of the light guide film is avoided. By adoption of the tensioning mechanisms, the light guide film can be kept to operate flatly in the coining process, and the coining effect is improved.

Description

technical field [0001] The invention relates to the technical field of light guide film equipment, in particular to a novel light guide film production equipment. Background technique [0002] Light guide film, which has the characteristics of ultra-thin, uniform luminescence, and multi-color changes, is used to guide light to a predetermined place. It is often used in backlight modules. The base material of the light guide film is mostly polymethyl methacrylate, which can Directly form micropatterns for light guide on the surface during injection molding. [0003] The micro-patterns on the surface of the existing light guide film are generally directly pressed and formed by a hard press, but the light guide film is generally brittle in texture, and the light guide film is easily crushed during the hard press printing process, causing the The scrap rate of the product is high. Contents of the invention [0004] In order to solve the above problems, the present invention ...
