Description

3D printer after treatment machine

The present invention relates to a 3D printer post-processing machine, and more particularly, since the acetone capsule is mounted on the capsule insertion unit and vaporized by ultrasonic vibration, the user can prevent the user from inhaling harmful gas when acetone is injected. The present invention relates to a 3D printer post-processing machine capable of finely treating the surface of a 3D printer output by installing a camera and an auxiliary injection nozzle which can be moved up and down inside.

3D printing is attracting attention as the core of the paradigm shift in the manufacturing industry through digital design drawings and 3D printers. Anyone can produce the products they need anywhere in the world. 3D printing itself has been mainly used for prototyping at the production site since the late 1980s, but with the development of material technology, it has been expanded to not only plastic but also glass and metal. The 3D printing process is designed using a 3D design program, etc. on a computer, and then stored in a predetermined data form, and analyzed by dividing the three-dimensional design into thin horizontal layers as if the 3D printer is 'differentially' and then design file. The three-dimensional model is completed by stacking materials from the bottom to the top as shown on the figure. In other words, it uses both the finely divided fine powder and the integral principle of combining these finely divided pieces into the original one.

The 3D printing method can be categorized by process method (solid, liquid, powder-based), that is, FDM (solid-based, resin extrusion technology), SLA (liquid-based photocurable resin molding technology), DLP (digital optical technology), It can be classified into SLS (powder-based rapid molding technology). In addition, 3D printing techniques may be classified according to whether the material used is a liquid, a solid or a powder, or how the shape is formed with the material.

In the case of the FDM method, materials such as solid plastics, which are soluble in heat, are pulled out like a thread and melted, and piled up by melting them. Spray to form a shape.

In the case of the SLA method, a laser is applied to a tank containing liquid photo-curable plastic in the form of light, and the layer is hardened one by one.As the sculpting plate is lowered in the tank, the hardened material is accumulated. It is suitable for making shapes, but has the disadvantage of being expensive and expensive.

In the case of the DLP method, the resultant is obtained by spraying a thin film of photocured plastic reacting to a laser or strong ultraviolet light on a plate to obtain a result. Stack by spraying raw materials. This DLP method has the highest precision and enables fine expression, but it has a disadvantage of taking time and cost. The DLP method is advantageous in terms of precision, surface finish and manufacturing speed, but the FDM method is more advantageous in terms of material strength.

In the case of the FDM type 3D printer as described above, the cost is relatively low, various materials can be added, and the durability of the model is strong, while the manufacturing speed is long, and the precision is not very high. For this reason, the post-treatment process is necessary because the thickness of the material injector clearly shows the layer on the surface and the surface of the finished product is rough. Thus, the post-treatment may be performed using a general fumigator. Since the 3D printer molded surface treatment device is a form in which acetone is heated and vaporized, heated acetone may explode and may present a safety risk to the user. have. In addition, the surface treatment apparatus of the conventional type of heating acetone is difficult to uniform surface treatment of the 3D three-dimensional fabric because the size and particle amount of the acetone vaporized particles vary depending on the heating temperature of the acetone.

In addition, there was a problem that the user inhales harmful gases when acetone is exposed to the atmosphere when acetone is input, and there is a problem that impairs the user's convenience because the user must control the surface treatment device while watching the surface treatment state directly. .

After the injection of the acetone fine particles, the operation stops and enters the standby mode so that the injected acetone fine particles can melt the surface of the 3D printer output 900, at which time the internal operation state notification LED light 215 lights up in white. The convection fan 203 continues to rotate at low speed to dry the 3D printer output 900.

At the same time, the discharge hole 303a is opened by the solenoid valve (not shown), so that the acetone solution in the liquid state inside the working part 200 is connected to the discharge hole 303a and the discharge hole 303a. Collected in the collecting container 305 through the hose 304, some of the acetone fine particles are moved to the water tank unit 600 through the discharge hose 304.

When the standby state ends, the opening and closing means 208 of the inlet opening and closing part 207 rotates to open the inlet hole 209 by the signal of the controller 101a, and at the same time, the opening and closing means 211 of the exhaust opening and closing part 210. When the exhaust hole 212 is rotated to open, the convection fan 203 rotates at high speed while the outside air introduced through the inflow part 105 is introduced into the work part 200 through the inlet hole 209. Afterwards, the tank unit of the exhaust unit 300 may be sequentially passed through the exhaust hole 212 and the exhaust hose 214 together with the acetone fine particles remaining in the work unit 200 by the operation of the exhaust fan 213. 600, and the moved acetone fine particles pass through the water contained in the tank 600, so that most of the acetone fine particles are dissolved in water. At this time, some of the acetone fine particles moved to the water tank unit 600 through the discharge hole 303a and the discharge hose 304 also pass through the water contained in the water tank unit 600, and most of them are dissolved in the water. At this time, the internal operation state notification LED light 215 is turned blue.

After performing the exhaust operation halfway as described above, the exhaust operation is stopped, and the entire surface of the circumference of the 3D printer output 900 is photographed in real time through the camera 700, and the captured image is displayed on the display of the control panel 101. Alternatively, the display may be displayed through a separate display device (not shown) so that the user may grasp a portion where surface treatment is insufficient.

At this time, if insufficient parts are not found, the above-described exhaust process is continuously performed, and if insufficient parts are found, the supplementary work is performed.

Complementary work for areas lacking surface treatment can be carried out selectively in two ways.

First, after the user checks the photographed image through the display of the control panel panel 101 or a separate display device (not shown), the user grasps a portion where surface treatment is insufficient, and the user directly controls the control panel panel 101. After rotating the holder 202 so that the surface of the surface treatment is insufficient to face the auxiliary spray nozzle 800, the auxiliary spray nozzle 800 is moved up and down to further spray acetone fine particles on the surface of the surface spray treatment. Complementary work can be performed.

Second, after checking the images photographed by the camera 700 through the display of the control panel panel 101 or a separate display device (not shown), the user clicks on the image corresponding to the insufficient surface treatment. When the control unit 101a automatically rotates the holder 202 so that the surface corresponding to the clicked image of the entire circumference of the 3D printer output 900 faces the auxiliary injection nozzle 800, the auxiliary injection nozzle 800 After moving up and down, the auxiliary injection nozzle 800 can be automatically supplemented by additional injection of acetone fine particles.

The discharge hole 303a is locked by a solenoid valve (not shown) during the supplementary work as described above, and in the supplementary work, the standby state and the exhaust process for drying the 3D printer output 900 are performed as in the present work. The camera 700 may retake the entire circumference of the 3D printer output 900 in real time, and display the captured image on the display of the control panel 101 or through a separate display device (not shown). In addition, the user may perform a process of identifying a portion where surface treatment is insufficient.

When the surface treatment work, the supplementary work and the exhaust work as described above, the concentration and the working part of the acetone microparticles in real time in the VOC sensor 204 and the temperature sensor 205 installed on the inner top of the working part 200 Measure the temperature inside the 200.

When the concentration of the acetone fine particles in the working part 200 measured by the VOC sensor 204 exceeds a preset reference value, the main locking device 302 and the auxiliary locking device 307 by the locking signal of the controller 101a. ) Keeps the front door 201 of the work unit 200 in a locked state, and the main lock device is released by the unlocking signal of the controller 101a when the measured concentration of acetone fine particles falls below a preset reference value. The 302 and the auxiliary locking device 307 release the locked state of the front door 201.

In addition, since the acetone fine particles may be ignited when the internal temperature of the work part 200 measured by the temperature sensor 205 is higher than the reference temperature, the controller 101a generates a warning signal. At this time, the warning to the user according to the warning signal of the control unit 101a may use a variety of known methods such as generating a warning sound or displaying a warning message on the display of the control panel panel 101.

Therefore, the locked state of the front door 201 of the work part 200 is released only when the acetone concentration of the inside of the work part 200 measured by the VOC sensor 204 falls below a predetermined reference value by the exhaust operation to release the front door ( 201), the 3D printer output 900 can be taken out after the surface treatment is completed. At this time, when the acetone concentration inside the working part 200 measured by the VOC sensor 204 falls below a preset reference value, the internal operation state notification LED light 215 is turned green to indicate that it is safe.

On the other hand, the acetone fine particles discharged through the exhaust process passes through the water contained in the water tank 600, at this time, most of the acetone fine particles are dissolved in water. At this time, some of the acetone fine particles moved to the water tank unit 600 through the discharge hole 303a and the discharge hose 304 also pass through the water contained in the water tank unit 600, and most of them are dissolved in the water.

Thereafter, the remaining acetone fine particles move through the through hole 602 to pass through the carbon filter 601a and the catalyst filter 602a, and then are discharged to the outside through the discharge unit 306.

Since the 3D printer post-processing machine according to the present invention attaches the acetone capsule to the capsule insertion part and covers the cover to completely encapsulate the capsule insertion part and then vaporizes it by ultrasonic vibration, the acetone is not exposed to the outside when the acetone is injected at all. This leakage to the outside can prevent the user from inhaling.

In addition, by installing the camera and the sub-injection nozzle which can move up and down inside the work part, the entire surface of the 3D printer output can be photographed through the camera to grasp the lack of surface treatment and to supplement the work through the sub-injection nozzle. It is possible to fine-tune the surface of 3D printer output.

In addition, when the camera photographs the surface of the 3D printer output, the controller can grasp the surface roughness of the 3D printer output using the captured image and automatically calculate the working time.

In addition, a VOC sensor and a temperature sensor are formed on the upper part of the work part, and the concentration of the inside of the work part is measured in real time through the VOC sensor. When the concentration exceeds the reference value, the locking state of the front door is maintained, and the concentration is less than the reference value. Since the front door can be opened by releasing the locking state only when it is dropped, the acetone can be prevented from leaking to the outside and the user can measure the temperature in real time with the temperature sensor to warn the user when the internal temperature is high. Therefore, the user can use it safely.

In addition, by separately providing an exhaust unit at the bottom of the working part to purify the acetone discharged to the exhaust unit through the exhaust portion after the surface treatment through the water and the filter, and then discharged to the outside, to prevent the user from inhaling the vaporized acetone fine particles. And acetone is almost completely diluted to release harmless water, so there is no problem of environmental pollution.

In addition, an airtight packing is formed in the front door of the work part, and when the front door is closed, the inside of the work part is completely sealed to prevent leakage of acetone.

In addition, the internal operating state notification LED lighting is formed on the upper part of the work unit, and the user can intuitively grasp the current working state by changing the lighting of different colors according to the operation of the surface processor.
