Problems solved by technology

[0003] At present, the 3D printing industry mostly uses conventional ultrasonic cleaning machines, combined with alcohol, which has high safety risks and environmental protection pressure.
At the same time, there is a lot of manual intervention. For places that are not clean, they are often washed manually with an air gun, which is harmful to the health of employees.
In addition, there is no accumulation in the cleaning process of workpieces. Different sizes and different sizes are all solved by manual intervention, and the degree of automation is low.
[0004] At present, the automatic cleaning industry has not paid much attention to the cleaning process of 3D printing products, and there is no corresponding solution. After exploring the process and combining a large number of basic tests, we have provided a basically complete cleaning solution for the 3D printing industry.

Embodiment 1

[0037] According to the preparation method of an automatic cleaning equipment for SLA three-dimensional printing provided by the present invention, the preparation process is as follows: figure 1 shown, including the following steps:

[0038] Step 1: Put the workpiece printed by the SLA equipment into the cleaning equipment as a whole or dispersedly;

[0039] Step 2: Select a plan with a workpiece height of 200 or more. After starting the equipment, the horizontal feeding mechanism will automatically send the workpiece to the blowing station;

[0040] Step 3: Wind blowing strategy According to the characteristics of the workpiece, adopt the large air volume mode and repeat the wind blowing for 8 cycles, which can clean 70% of the residual resin;

[0041] Step 4: Send it to the spray station, adopt the intermittent spray mode, spray for 10 seconds, and at the same time, the workpiece moves repeatedly;

[0042] Step 5: Liquid attachment and scouring can further clean the surfa...

Embodiment 2

[0048] Step 1: Put the workpiece printed by the SLA equipment into the cleaning equipment as a whole or dispersedly;

[0049] Step 2: Select the workpiece plan with a height of less than 200mm. After starting the equipment, the horizontal feeding mechanism will automatically send the workpiece to the blowing station;

[0050] Step 3: The wind blowing strategy adopts the medium air volume mode according to the characteristics of the workpiece, and automatically adjusts the distance between the blowing outlets to a closer position, and repeats the wind blowing for 5 cycles, which can clean 75% of the residual resin;

[0051] Step 4: Send it to the spray station, adopt the continuous spray mode, spray for 5 seconds, and at the same time, the workpiece moves repeatedly;

[0052] Step 5: Liquid attachment and scouring can further clean the surface of the workpiece, and the cleanliness can reach 90% at this time;

[0053] Step 6: Grasp by the vertical mechanism, and then move horiz...

Embodiment 3

[0058] The automatic cleaning system of the SLA three-dimensional printing workpiece provided according to the present invention includes:

[0059] Module M1: Removal of residual resin on the surface by wind blowing process;

[0060] Module M2: use spraying process to further clean the residual resin on the surface of the workpiece;

[0061] Module M3: Use soaking process to thoroughly clean the workpiece;

[0062] Module M4: Using an automated material delivery platform, the workpiece is automatically transported and cleaned in the whole process from loading to cleaning.

[0063] Preferably, the wind blowing process includes: through four high-pressure air pipes with a diameter of 2mm, blowing the surface of the workpiece with a wind pressure of 0.6MPa, and at the same time reciprocating the material delivery platform, and removing the residual resin on the surface of the workpiece by wind pressure .

[0064] Preferably, the spraying process includes: using a 6L / min, 10bar p...

Abstract

The invention provides an automatic washing method and system for an SLA three-dimensional printing workpiece. The automatic washing method comprises the steps that firstly, residual resin on the surface is removed through an air blowing process; secondly, the residual resin on the surface of the workpiece is further removed through a spraying process; thirdly, the workpiece is thoroughly cleanedthrough a soaking process; and fourthly, the workpiece is automatically conveyed and washed in the whole process from feeding to cleaning through an automatic material conveying platform. By means ofthe combined process method of air blowing, spraying and soaking, the problems that it is difficult to wash the surface of an SLA printing resin piece and the automation degree is low are solved, andbreakthrough on the important bottleneck is achieved for automation of the SLA product production process.

Description

technical field [0001] The invention relates to the technical field of automatic cleaning, in particular to an automatic cleaning method and system for SLA three-dimensional printing workpieces. Background technique [0002] 3D printing technology is fast and low-cost, can manufacture complex parts, and can eliminate defects in advance. It is precisely because of the complex structure and various forms of the printed workpiece that it is particularly difficult to clean the surface of the workpiece in the post-processing stage. At present, most of the industry uses conventional ultrasonic equipment and alcohol cleaning solutions. This kind of scheme has a low degree of automation, and workers often have to stand by the ultrasonic pool and participate manually, so the safety risk is high and the injury to the human body is also relatively serious. [0003] At present, the 3D printing industry mostly uses conventional ultrasonic cleaning machines combined with alcohol, which p...
