[0002] LCD3D printer is a 3D printer that uses the principle of liquid resin photocuring. It uses liquid crystal display (LCD) imaging technology. Under the drive of a computer and display driver circuit, a computer program first discretizes the three-dimensional model into layers of plane graphics. Then the display driver circuit controls the LCD screen to convert the specified position of the screen into a transparent area corresponding to the plane graphics (other areas remain opaque black), so that the ultraviolet light source below the LCD screen can pass through the LCD screen and irradiate the liquid resin above the transparent area, causing the resin to undergo a curing reaction and become solid.

[0026] The present application is described in detail below with reference to the accompanying drawings and specific implementation methods.

[0027] Example 1

[0028] See also Figure 1-7 In the embodiment, a snap-on material slot of an LCD 3D printing device is provided, comprising: a printer body 1, a material slot 11 is provided on the top of the printer body 1, a mounting slot 12 is provided at the bottom of the material slot 11, two frames 13 are provided inside the mounting slot 12, a release film 14 is provided between the two frames 13, a printing platform 15 is fixedly installed on the top of the printer body 1, and a disassembly and assembly component is provided on the material slot 11 to facilitate replacement of the release film 14, and the disassembly and assembly component comprises: a movable slot 2, a guide frame 21, a pull rod 22, a card block a23, a fixed frame 24 and a card slot 25.

[0029] Among them, a number of equally distributed sockets 4 are respectively opened on the four sides of the two frames 13, and a number of threaded holes 41 matching the number of sockets 4 are respectively opened on the fixing frame 24. Screws 42 are respectively inserted into the sockets 4, and one end of the screw 42 extends into the threaded hole 41.

[0030] When in use, place the release film 14 between the two frames 13, pass the screw 42 through the socket 4 and the release film 14, and screw one end of the screw 42 into the threaded hole 41, so as to install the release film 14 between the two frames 13, and then install the frames 13 into the installation groove 12 at the bottom of the material tank 11, fix the frames 13 by disassembling and assembling the components, and then install the material tank 11 on the printer body 1 for use, pour the resin into the material tank 11, move the printing platform 15 to the inside of the material tank 11, and print on the printing platform 15 through the printer body 1.

[0031] Example 2

[0032] On the basis of Example 1, a plurality of movable grooves 2 which are guided by the inside of the installation groove 12 are respectively opened on the opposite sides of the material trough 11, a guide frame 21 is fixedly connected to the inside of the movable groove 2, a pull rod 22 is slidably connected to the inside of the guide frame 21, one end of the pull rod 22 is fixedly connected to a card block a23, a fixed frame 24 is fixedly connected to the frame 13 at the top, and card slots 25 which are used to match the plurality of movable grooves 2 are respectively opened on the opposite sides of the fixed frame 24, one end of the pull rod 22 passes through the material trough 11 and extends to the outside and A limit plate 26 is fixedly connected, a handle 27 is fixedly connected to one side of the limit plate 26, two symmetrically arranged guide rods 28 are fixedly connected between the block a23 and the limit plate 26, the outside of the guide rod 28 passes through the guide frame 21 and the material trough 11, a pressure plate 29 is fixedly connected to the outside of the pull rod 22 near the guide frame 21, a washer 210 and a spring a211 are sleeved on the outside of the pull rod 22, one end of the spring a211 is connected to the pressure plate 29, and the other end of the spring a211 is connected to the washer 210.

[0033] When installing the frame 13, the frame 13 with the fixed frame 24 is inserted into the installation groove 12. Due to the inclined setting of the fixed frame 24 and one side of the card block a23, the inclined surface of the fixed frame 24 fits with the inclined surface of the card block a23 during insertion, so that the card block a23 is pushed into the movable groove 2. The guide frame 21 can move the moving range of the card block a23. When the card block a23 moves, it pushes the pull rod 22 to move. When the pull rod 22 moves, it drives the pressure plate 29 to move to one side. When the pressure plate 29 moves, it cooperates with the fixed gasket 210 to squeeze the spring a211. At the same time, when the pull rod 22 moves, it pushes the limit plate 26 and the handle 27 to move, so that the fixed frame 24 moves the card block a23 Push it open and insert it to the top of the installation slot 12. At this time, the movable slot 2 is flush with the card slot 25. At this time, the spring a211 pushes the pressure plate 29 to move to one side of the card slot 25 after the card block a23 loses its restriction. The pressure plate 29 drives the pull rod 22 and the card block a23 to be pushed into the card slot 25, thereby fixing the fixed frame 24, thereby installing the frame 13 in the installation slot 12. When the release film 14 needs to be replaced, pull the handle 27 to drive the pull rod 22 to move. During the movement, the pull rod 22 drives the card block a23 to move from the inside of the card slot 25 to the movable slot 2, thereby releasing the fixation of the fixed frame 24, thereby removing the frame 13 from the installation slot 12 and replacing the release film 14.

[0034] Example 3

[0035] On the basis of Example 1, the material trough 11 is fixedly connected with grab ears 3 on opposite sides, and two plug-in blocks 31 are fixedly connected to the bottom of the two grab ears 3, and two pairs of plug-in seats 32 are fixedly connected to the top of the printer body 1. A plug-in hole 33 is opened on the top of the plug-in hole 33, and movable cavities 34 are opened on opposite sides of the plug-in hole 33. Two symmetrically arranged moving blocks 35 are respectively arranged inside the two movable cavities 34. The two moving blocks 35 are respectively fixedly connected with a card block b36 used in conjunction with the plug-in block 31 at the opposite side near the top position, and the two movable cavities 34 are respectively fixedly connected with a fixed Plate 37, the two fixed plates 37 are respectively slidably connected with matching moving frames 38, the two moving blocks 35 are respectively provided with through holes for accommodating the moving frames 38 to pass through, the opposite ends of the two moving blocks 35 respectively pass through the two through holes and are respectively connected to the two moving blocks 35, the opposite sides of the socket 32 ​​are respectively provided with sliding grooves, the two sliding grooves are respectively slidably connected with pressing blocks 39, the opposite sides of the two pressing blocks 39 are respectively fixedly connected with connecting rods 310, the outside of the connecting rods 310 are respectively sleeved with springs b311, and the opposite ends of the springs b311 are respectively connected to the pressing blocks 39 and the fixed plate 37.

[0036] When installing the material trough 11, the two plug-in blocks 31 at the bottom of the grab ear 3 are respectively inserted into the plug-in holes 33 in the two pairs of plug-in seats 32. When inserted, the two inclined surfaces at the bottom of the plug-in block 31 are engaged with the two card blocks b36, thereby separating the two card blocks b36 to the opposite sides. The card block b36 drives the moving block 35 to move, and the moving block 35 drives the two moving frames 38 and the connecting rod 310 to move. When the connecting rod 310 moves, it drives the pressing block 39 to move inward. When the pressing block 39 moves, it squeezes the spring b311. When the plug-in block 31 passes through the two card blocks b36, it is pushed under the action of the spring b311. The moving block 35 moves, thereby cooperating with the two card blocks b36 to clamp the plug-in block 31. When the material trough 11 needs to be removed, the two pressing blocks 39 are pressed at the same time to make the two pressing blocks 39 move closer to the center. The pressing blocks 39 push the connecting rod 310 and the moving frame 38 to move. The moving frame 38 pushes the two moving blocks 35 to move to both sides, so that the two card blocks b36 separate the plug-in block 31, thereby releasing the fixation of the plug-in block 31, grab the two grab ears 3 to lift the material trough 11, so that the plug-in block 31 is pulled out from the inside of the plug-in hole 33, so that the material trough 11 is removed from the printer body 1.
