Detailed description of the invention
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the present invention, is not intended to limit the present invention.
If Fig. 1-3 is embodiments of the invention schematic diagram, as seen from the figure, resin coating system of photosensitive curing forming machine of the present invention, comprise computer 1, scraper plate 4, pressure adjustable type vacuum generator 12, flexible pipe 13, liquid storage box 14, guide rail 15, Timing Belt 16, motor 17 and blade holder 21, computer 1 and motor 17 are electrically connected, and computer directly controls the running of motor 17; Motor 17 is connected by Timing Belt 16 with scraper plate 4; Scraper plate 4 is arranged in blade holder, is convenient to the cleaning of scraper plate 4, replacing and maintenance; Blade holder 21 is slidably arranged on guide rail 15, and blade holder can be carried scraper plate 4 and make horizontal reciprocating movement on guide rail 15; Scraper plate 4 has the cavity of bottom opening; Cavity, liquid storage box 14, pressure adjustable type vacuum generator 12 are connected by flexible pipe 13 order, make scraper plate 4 inside present negative pressure state by the effect of pressure adjustable type vacuum generator 12, the tension force capillarity due to resin surface can make there is a certain amount of resin in the cavity of scraper plate 4.Scraper plate sidewall is provided with window 22, is convenient to observe resin liquid height in cavity.
The bottom opening number of scraper plate 4 cavity is three, and cavity lower bottom part is divided into three runners by described three openings, thus realizes the repeatedly coating of resin.Intermediate flow channel is equipped with narrow meshed spoiler 27, can avoid because the reasons such as bracket lifting or scraper plate 4 rapid movement cause scraper plate 4 cavity to lose negative pressure.The opening of runner is " eight " font structure, and scraper plate 4 can be avoided to be scratched by workpiece.
The outer wall of scraper plate 4 two bottom sides is provided with the notch 24 concaved, and photosensitive resin liquid can be avoided to condense bottom scraper plate 4.
When resin coating system of photosensitive curing forming machine uses, the distance between described scraper plate 4 and resin liquid level is set as 0.2mm.
Job step:
Operationally: the individual-layer data that computer 1 designs according to workpiece or support Data Control laser beam and form a cured layer at the photosensitive resin liquid level of major trough do two-dimensional scan.When after one deck resin scanning solidification, computer 1 controls lifting platform and drives workpiece to decline the degree of depth of a cured layer, and computer 1 controls motor 17 makes scraper plate 4 level on guide rail 15 reciprocating motion by transmission mechanism such as Timing Belt 16 grade again.There is bottom scraper plate 4 cavity of opening, flexible pipe 13 one end is coupled, the other end is connected with pressure adjustable type vacuum generator 12 after liquid storage box 14, scraper plate 4 inside is made to present negative pressure state by the effect of pressure adjustable type vacuum generator 12, make there is a certain amount of resin in the cavity of scraper plate 4, and between strickle and liquid level, form the resin molding of thin layer, resin height we can carry out Real Time Observation by window 21.Due to the viscosity of photosensitive resin liquid, the resin liquid that lifting platform moves down rear surface of the work there will be the phenomenon protruded or cave in, when scraper plate 4 moves, the projection of uncured resin layer on workpiece can be struck off sunk part and then be filled and led up by the resin in cavity.Scraper plate 4 applies the resin liquid level of major trough 11, and the resin liquid in its cavity is used for the coating carrying out uncured resin layer at surface of the work, thus realizes high-quality coating.
Last it is noted that the foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, although with reference to previous embodiment to invention has been detailed description, for a person skilled in the art, it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
