It should be noted that, the existing LCD photocuring 3D printing mainly realizes the molding through the cooperation of the ultraviolet light source and the display screen 700, and the light emitted by the ultraviolet light source passes through the display screen 700 and irradiates on the liquid photosensitive resin, so that the hydraulic photosensitive resin realizes the photocuring effect and is finally molded into the molding model required by the 3D printing. Because the display 700 shows the use of two sheets of polarized material, with a liquid crystal solution between the two sheets of polarized material, the liquid crystal solution will cause the crystal to rearrange so that light cannot pass through them when current is passed through the liquid crystal solution. Thus, each crystal acts like a louver, both allowing light to pass through and blocking light. In the process of LCD photocuring 3D printing, whether light emitted by the ultraviolet light source irradiates on the liquid photosensitive resin above the crystal can be controlled by controlling the opening and closing of each crystal in the display screen 700 so as to realize photocuring and forming, so that the fixation and position stability of the display screen 700 are particularly important.

One way to fix the display screen 700 to the cover plate 300 in the prior art is by using adhesive tape. When the fixing is carried out by adopting a tape bonding mode, the fixing function can be realized in a static state of the photocuring printer, however, in the actual printing process, the display screen 700 generates transverse displacement due to the movement of the liquid photosensitive resin and the assembly of the display screen 700, and once the display screen 700 generates transverse displacement, each crystal position inside the display screen 700 is required to be changed, so that the forming precision of photocuring of the liquid photosensitive resin above each crystal position is influenced, and finally, a 3D printed product becomes a defective product. Because the utility model relates to a display screen 700 of the fixed subassembly of 3D printer screen that the embodiment provided can with fixed plate 200 adhesive connection, the display screen 700 and the two absorption connection with glass welt 100 of fixed plate 200 jointly, therefore display screen 700 can not take place to remove even receiving great horizontal effort, has guaranteed display screen 700's stability to the qualification rate of 3D printing product has been improved.

Another way to secure the display screen 700 to the cover plate 300 in the prior art is to use a large amount of sealant to completely secure the display screen 700 to the cover plate 300. However, if a large amount of sealant is used to completely fix the display screen 700 to the cover plate 300, the sealant must be completely removed to replace the display screen 700 when the display screen 700 is damaged and needs to be replaced, which brings great inconvenience to the worker. Because the utility model relates to a display screen 700 of the fixed subassembly of 3D printer screen that the embodiment provided can with fixed plate 200 adhesive connection, the two absorption connection with glass welt 100 jointly of display screen 700 and fixed plate 200. Therefore, when a problem occurs in the display screen 700, the flat cable 710 of the display screen 700 is directly untied, and after the external decorative tape is removed, the display screen 700 and the fixing plate 200 are lifted up in the longitudinal direction, so that the display screen 700 is separated from the glass lining plate 100, and the replacement is very easy and convenient.

In one embodiment, the plate surface of the fixing plate 200 has the same size as the screen of the display screen 700.

In another embodiment, the size of the plate surface of the fixing plate 200 is smaller than the size of the screen of the display screen 700, and it should be noted that the size of the plate surface of the fixing plate 200 is not limited, as long as the fixing plate 200 has the adsorption layer 210 on the side facing the glass lining plate 100, so that the glass lining plate 100 is adsorbed by the adsorption layer 210; the side of the fixing plate 200 facing away from the glass lining plate 100 has an adhesive layer 220, so that the display screen 700 and the adhesive layer 220 can be adhesively connected.
