Referring to FIG. 2 , in one embodiment, the number of adsorption layers 210 of the 3D printer screen fixing assembly provided by the present invention is one. One side of the adsorption layer 210 is fixedly connected to the side of the fixing plate 200 facing the glass backing plate 100 , and the other side of the adsorption layer 210 is connected to the glass backing plate 100 by adsorption. The adsorption layer 210 is connected to the glass backing plate 100 by adsorption, so that the fixing plate 200 and the glass backing plate 100 can be easily separated.

In another embodiment, the number of adsorption layers 210 of the 3D printer screen fixing assembly provided by the present invention is multiple, and the multiple adsorption layers 210 are arranged at intervals. One side of the at least one adsorption layer 210 is fixedly connected to the side of the fixing plate 200 facing the glass backing plate 100 , and the other side of the at least one adsorption layer 210 is connected to the glass backing plate 100 by adsorption. The adsorption layer 210 is connected to the glass backing plate 100 by adsorption, so that the fixing plate 200 and the glass backing plate 100 can be easily separated. Since there are multiple adsorption layers 210 , the service life of the fixed plate 200 is greatly enhanced. When the suction force of one of the adsorption layers 210 decreases, the other adsorption layers 210 can be used to achieve the connection between the fixed plate 200 and the glass backing plate 100 . Snap connection.

In still other embodiments, the materials of the multiple adsorption layers 210 of the 3D printer screen fixing assembly provided by the present invention are different, so that the fixing plate 200 can be adsorbed and connected with the glass fixing plate 200 with different friction coefficients.

It should be noted that the plurality of adsorption layers 210 may be arranged at intervals along the length direction of the fixing plate 200 , may also be arranged at intervals along the width direction of the fixing plate 200 , or may be arranged at intervals along the axis of the fixing plate 200 .

It should be noted that the number of the adsorption layers 210 may be four, five or six, etc., which is not limited, as long as the adsorption between the fixing plate 200 and the glass backing plate 100 can be realized connection function.

In one embodiment, the adsorption layer 210 of the screen fixing component of the 3D printer provided by the present invention is made of silica gel material, and the adhesive layer 220 is made of optical glue. The silica gel is attached to the glass backing plate 100 by adsorption, and the optical adhesive is bonded to the display screen 700 , so that the display screen 700 can be bonded and connected to the fixing plate 200 .

It should be noted that the existing LCD light-curing 3D printing is mainly realized by 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 is irradiated on the liquid photosensitive resin, so that the hydraulic photosensitive resin realizes It is cured by light and finally formed into a molding model required for 3D printing. Since the display screen 700 shows the use of two pieces of polarized material, between the two pieces of polarized material is a liquid crystal solution, and the passing of the current through the liquid crystal solution causes the crystals to rearrange so that light cannot pass through them. Thus, each crystal acts like a shutter, both allowing light to pass through and blocking it. In the process of LCD light-curing 3D printing, by controlling the opening and closing of each crystal in the display screen 700, it is possible to control whether the light emitted by the ultraviolet light source irradiates the liquid photosensitive resin above the crystal to achieve photo-curing and molding. Therefore, the fixation and position stability of the display screen 700 are particularly important.

In the prior art, one way of fixing the display screen 700 and the cover plate 300 is to use adhesive tapes. When it is fixed by adhesive tape, it can play a fixed role when the photo-curing printer is stationary. However, in the actual printing process, the movement of the liquid photosensitive resin and the assembly of the display screen 700 will cause the display screen 700 to be horizontally displaced. Once the display screen 700 is displaced laterally, the position of each crystal inside the display screen 700 is bound to change, which in turn affects the molding accuracy of the photocuring liquid photosensitive resin above each crystal position, resulting in the final 3D printing. products become defective products. Since the display screen 700 of the screen fixing assembly of the 3D printer provided by an embodiment of the present invention can be adhesively connected with the fixing plate 200, the display screen 700 and the fixing plate 200 are both attached to the glass backing plate 100 by adsorption, so the display screen 700 can Even if it is subjected to a large lateral force, it will not move, which ensures the stability of the display screen 700, thereby improving the pass rate of 3D printed products.

In the prior art, another way to fix the display screen 700 and the cover plate 300 is to use a large amount of sealant to completely fix the display screen 700 on the cover plate 300 . However, if a large amount of sealant is used to completely fix the display screen 700 on the cover plate 300, when there is a problem with the display screen 700 and the display screen 700 needs to be replaced, the sealant must be completely removed before the replacement can be achieved, which brings great harm to the staff. a great inconvenience. Since the display screen 700 of the 3D printer screen fixing assembly provided by an embodiment of the present invention can be adhesively connected to the fixing plate 200 , the display screen 700 and the fixing plate 200 are both connected to the glass backing plate 100 by suction.
