Problems solved by technology

[0006] 1. The manual cleaning process is cumbersome and the cleaning efficiency is low;
[0007] 2. Shaking the container manually during the cleaning process makes the alcohol splash, resulting in pollution of the operator and the operating environment and waste of alcohol;
[0009] 4. Cleaning depends on manual adjustment of the cleaning angle. The cleaning is not sufficient. After further curing and molding, the excess resin at the corners will change the shape and structure of the model, and the accuracy of the model will be seriously affected. As a result, the SLA printer cannot take advantage of the high printing accuracy.

Embodiment 1

[0039] Embodiment 1: as Figure 1-5As shown, a model cleaning device based on light-curing 3D printing includes a housing 1, a cleaning mechanism 2, and a loading table 3; The top end extends downwards to form an installation part 12, and an installation groove 13 is provided above the installation part 12; the cleaning mechanism 2 includes a water pump 21, a flow divider 22, a liquid inlet pipe 23, a liquid outlet pipe 24 and an impeller 25; the water pump 21 The bottom end of the housing 1 is fixedly connected by bolts. The lower part of the flow divider 22 is fixedly connected with four brackets by bolts. The brackets are fixedly connected to the bottom end of the housing 1 by bolts. To the inner bottom of the housing 1, the liquid outlet of the water pump 21 is fixedly connected to the joint at the bottom of the flow divider 22 through a pipeline. In this embodiment, the water pump 21 can be used for diving, and its model is HQB-2200; The interior of the installation groo...

Embodiment 2

[0045] Embodiment 2: This embodiment is different from Embodiment 1. The difference is that in Embodiment 1, when cleaning the model, only the surroundings and the top of the model can be cleaned, but the bottom of the model cannot be cleaned; while in this embodiment , can avoid the above defects, specifically:

[0046] The cleaning mechanism 2 also includes a shower head 29; the shower head 29 is screwed to the top of the flow divider 22, and is located below the material placement platform 3, and the material placement platform 3 is provided with several through holes 32; When the present embodiment is working, the alcohol branch is sprayed upwards from the shower head 29 at the bottom of the material placing table 3, so as to achieve the purpose of all-round cleaning.

[0047] Apart from this, this embodiment is completely the same as Embodiment 1, which will not be repeated here.

Embodiment 3

[0048] Embodiment 3: This embodiment is a further improvement of Embodiment 2. The main improvement is that when placing the model in Embodiment 2, the model is likely to interfere with the drain pipe, which is troublesome to use; and in this embodiment, The above drawbacks can be avoided, specifically:

[0049] It also includes a lifting mechanism 5; the lifting mechanism 5 includes symmetrically arranged slideways I51, slideways II52, connecting rods I53, connecting rods II54, sliders I55 and sliders II56, and the slideways I51 are laterally fixedly connected by bolts The lower part of the inner wall of the housing 1 on both sides adjacent to the door 11, the slideway II52 is vertically fixedly connected to the inner wall of the housing 1 above the slideway I51 by bolts, and the slider I55 and the slider II56 are slidably connected to the slideway I51 and the slideway I51 respectively. In the inner chute of track II52, the size of slider I55 and slider II56 is smaller than t...

Abstract

The invention discloses a model cleaning device based on photocuring 3D printing. The model cleaning device comprises a shell, a cleaning mechanism and a material storing table, wherein one side of the shell is opened and a door is arranged at the opening; the top end of the inner wall of the shell extends downwards to form a mounting part; a mounting groove is arranged above the mounting part; the cleaning mechanism comprises a water pump, a flow divider, a liquid inlet pipe, a liquid outlet pipe and an impeller; the water pump and the flow divider are both arranged at the bottom end in the shell; a liquid inlet of the water pump is connected with a pipeline and extends to the bottom end in the shell; a liquid outlet of the water pump is connected with the flow divider through the pipeline; the impeller is arranged in the mounting groove and is rotatably connected to the mounting part through a pivot at the bottom; a cover plate is detachably and fixedly connected to the upper openingof the mounting groove; a liquid discharge hole is formed in the center of the impeller; and the liquid discharge hole penetrates through the impeller and extends into the pivot. According to the model cleaning device based on photocuring 3D printing, the traditional manual cleaning is replaced by equipment cleaning, so that the cleaning process is more convenient and fast, the working efficiencyis greatly improved, and the cleaning effect is more perfect.

Description

technical field [0001] The invention relates to the technical field of 3D printing auxiliary equipment, in particular to a model cleaning device based on photocuring 3D printing. Background technique [0002] SLA3D printer, also known as light-curing 3D printer, is a 3D printing device that uses the principle of stereolithography technology. It is a very important process technology in the molding process of 3D printing technology. [0003] Use a laser with a specific wavelength and intensity to focus on the surface of the photocurable material (the material is mainly a liquid photosensitive resin), so that it is solidified sequentially from point to line, from line to surface, and completes a layer of drawing work, and then the lifting platform moves in the vertical direction The height of one layer is then solidified into another layer, so that layers are superimposed to form a three-dimensional entity. [0004] SLA is the earliest practical rapid prototyping technology. ...
