Problems solved by technology

[0006] The pallet adopts the working method of diving, rising and waiting mainly to use the leveling of the liquid itself, but the movement process of the pallet takes a lot of time, and the auxiliary work time is longer, resulting in a decrease in production efficiency, and when the layer thickness is small , the edge of the scraper is easy to touch the cured production layer, thus destroying the workpiece and reducing the success rate of the workpiece
[0007] Because the negative pressure adsorption device uses a micro-diaphragm vacuum pump to directly provide negative pressure and control the negative pressure through a pressure regulating module, its matching cost is relatively high

Embodiment 1

[0030] Figure 1-2 It is a schematic diagram of an embodiment of the present invention. It can be seen from the figure that the negative pressure leveling device of the photosensitive curing molding machine includes a positive pressure air source, negative pressure equipment, and a leveler. The leveler has a cavity 5, and the negative pressure equipment includes Intake pipe 1, nozzle 2, air outlet pipe 3, air suction pipe 4, the air inlet pipe 1, nozzle 2, air outlet pipe 3 are connected in sequence, one end of air suction pipe 4 is vertically connected with air outlet pipe 3, and the other end is connected with cavity 5 The positive pressure air source is connected to the intake pipe 1 . The positive pressure air source is a small air compressor, which reduces equipment operating costs.

[0031] When the device is working, negative pressure will be generated in the cavity 5 to absorb a certain amount of photosensitive resin, and the photosensitive resin stored in the cavity ...

Embodiment 2

[0038] The negative pressure scraping device of the photosensitive curing molding machine includes a positive pressure air source, negative pressure equipment, and a scraper, and the scraper has a cavity 5,

[0039] The negative pressure equipment includes an air inlet pipe 1, a nozzle 2, an air outlet pipe 3, and an air suction pipe 4. The air inlet pipe 1, the nozzle 2, and the air outlet pipe 3 are connected in sequence, and one end of the air suction pipe 4 is vertically connected with the air outlet pipe 3. The other end is connected with the cavity 5 , and the positive pressure air source is connected with the air intake pipe 1 .

[0040] When the device is working, negative pressure will be generated in the cavity 5 to absorb a certain amount of photosensitive resin, and the photosensitive resin stored in the cavity 5 will be used to supplement the recessed part, which can effectively improve the effect of photosensitive curing and recoating. There is a distance of 0.2m...

Description

technical field [0001] The invention relates to the field of photocuring rapid prototyping machines, in particular to a negative pressure scraping device for photocuring and prototyping machines. Background technique [0002] Rapid prototyping technology is a manufacturing technology based on the principle of layer-by-layer superposition of materials to slice and layer the data obtained from CAD three-dimensional digital models, and build them up layer by layer through special equipment. Photosensitive curing rapid prototyping is that the ultraviolet beam forms a focused spot on the resin liquid surface through the beam focusing device and the beam scanning device, so that the resin liquid surface is photosensitive and cured. Then the liquid is coated with a layer of resin on the surface of the cured layer, and then cured by light, and so on to finally make the whole workpiece. [0003] Since the production of the workpiece is to move down to the next layer in the vertical ...
