Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
As fig. 1 and fig. 2, this embodiment provides a quick printing device of LCD3D printer, including liftable platform board 1, silo 2, from type membrane 3, LCD screen 6, medium plate 7 and vacuum adsorption device. Liftable landing slab 1 is conventional setting, drives landing slab 1 up-and-down motion through conventional elevating system and accomplishes the printing. Platform board 1 is located 2 tops of silo, and from type membrane 3 being located silo 2, middle plate 7 is located 2 below of silo, and LCD screen 6 is located on middle plate 7. The middle plate 7 is provided with a through hole, the vacuum adsorption device is communicated with the through hole, and the through hole is positioned below the trough 2.
Conventional 3D printer prints the process, and the upward movement of landing slab 1 at every turn can adsorb the type membrane 3 and live, follows landing slab 1 from type membrane 3 and up the lifting, needs the distance more than the deformation 5 mm. In the process, the lifting speed of the platform plate 1 cannot be too high, otherwise, the printed model is easy to deform or fall off due to the deformation of the release film 3, and the printing efficiency and the yield are low in the process. In the long-time printing process, even if the release film 3 is not damaged, the deformation is caused, so that the printing precision is reduced and the printing efficiency is lowered.
In this embodiment, by providing the vacuum adsorption device, before printing starts, the vacuum adsorption device is turned on, and the release film 3 is adsorbed from the lower side by vacuum, so that the release film 3 is adsorbed on the LCD screen 6. During printing, the release film 3 and the platform plate 1 can be quickly separated, and excessive deformation cannot be caused. Because being adsorbed from type membrane 3, landing slab 1 can rise fast, and landing slab 1 only need rise 1mm can simultaneously, very big improvement printing speed.
As shown in fig. 1, in order to ensure the vacuum adsorption effect, a rubber sealing ring is arranged between the middle plate 7 and the trough 2, the middle plate 7 is provided with a groove, and the groove can realize the rapid placement of the rubber sealing ring 4, so that the effects of positioning and increasing the sealing performance are achieved. The peripheral size in rubber seal 4 and the bottom of silo 2 equals, and the through-hole is located rubber seal 4. The gap between the LCD screen 6 and the release film 3 is eliminated under the action of vacuum pumping, and the release film 3 is firmly adsorbed on the LCD screen 6. This kind of mode guarantees that all points from type membrane 3 are adsorbed on LCD screen 6, and the process that the platform board 1 rises basically can not lead to the fact deformation from type membrane 3.
As shown in fig. 1, in order to further improve the vacuum absorption effect, the edge of the LCD screen 6 is provided with a screen edge sealing sticker 5, and the screen edge sealing sticker 5 seals the LCD screen 6 on the middle plate 7. The edge of the screen is sealed and pasted with 5 to be provided with air holes, the air holes correspond to the through holes of the middle plate 7, and the air holes and the through holes are used as channels for extracting air.
As shown in fig. 1 and 2, the vacuum suction device is disposed below the middle plate 7, and may be disposed at other positions as needed. The vacuum adsorption device comprises an air pipe joint 8, an air pipe 9 and a micro vacuum pump 10, wherein the micro vacuum pump 10 is connected with the air pipe joint 8 through the air pipe 9, and the air pipe joint 8 is connected with the through hole. A gap between the LCD screen 6 and the release film 3 forms a closed vacuum-pumping system through the air holes, the through holes, the air pipe joint 8, the air pipe 9 and the micro vacuum pump 10.
Adopt above-mentioned each technical scheme, the utility model discloses increased the structure of evacuation, made from the type membrane firm absorption on the LCD screen, print the in-process from the type membrane absorption can not produce deformation on the screen to can shorten the lifting distance when from the shape, thereby realize printing fast, print the model success rate height, can increase from the life of type membrane.
The above description is only exemplary of the present invention and should not be construed as limiting the present invention, and any modifications, equivalents and improvements made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
