Description

Technical Field

[0001] The present application relates to the technical field of 3D printing equipment, and in particular to an installation cabinet and a 3D printing equipment. Background Art

[0002] 3D printing equipment is a device that rapidly manufactures three-dimensional objects based on 3D CAD data. 3D printing methods primarily include powder bed fusion, binder jetting, material extrusion, and directed energy deposition. Directed energy deposition typically melts wire material in a molten pool generated by a laser or electron beam. Once the molten material solidifies and takes shape, it forms the desired part of the product.

[0003] Currently, 3D printing equipment relies primarily on indoor lighting to illuminate the print head, allowing operators to quickly monitor the shape of the printed product. However, in some cases, the brightness of indoor lighting is low, making it difficult to clearly see the printed product, and this needs to be improved. Utility Model Content

[0004] In view of this, the present application provides an installation cabinet, which is equipped with a fill light to facilitate operators to view the shape of the product being printed.

[0005] An embodiment of the present application provides an installation cabinet, comprising a cabinet body and a fill light. An enclosed installation space is provided inside the cabinet body. The cabinet body comprises a mounting frame, a back panel, a door panel, a bottom panel, a top panel and two side panels. The back panel and the door panel are spaced apart along a first direction, the two side panels are spaced apart along a second direction, and the bottom panel and the top panel are spaced apart along a third direction. The back panel, the door panel, the bottom panel, the top panel and the two side panels are all connected to the mounting frame and enclose an installation space. At least part of the door panel and / or the side panel is transparent. The installation space is used to accommodate a 3D printing device, and the first direction, the second direction and the third direction are perpendicular to each other. The fill light is arranged in the installation space and connected to the inner wall of the cabinet body. The fill light is located at the intersection of the top panel and the door panel or the side panel. The fill light is configured to project illumination light toward the print head portion of the 3D printing device to illuminate the print head portion of the 3D printing device.

[0006] In the above embodiment, the fill light is located at the intersection of the top panel and the side panel or door panel, which can minimize the installation space occupied by the fill light and reduce the possibility of interference with the 3D printing device. At the same time, the 3D printing device can be installed in a closed installation space, which can reduce the gas, dust, etc. generated during the printing process and reduce harm to the human body. By illuminating the print head of the 3D printing device with the fill light, the operator can clearly view and monitor the shape of the printed product through the transparent part of the cabinet.

[0007] In some embodiments of the present application, the installation cabinet further includes a mounting plate, which is connected to the inner wall of the cabinet body, the mounting plate is inclined relative to the top plate, and the fill light is connected to the mounting plate.

The exhaust component and the sensing component are electrically connected to the control component. When the data detected by the sensing component exceeds a predetermined threshold, the control component controls the exhaust component to exhaust air.

[0010] In the above embodiment, when the temperature or humidity data detected by the sensing component exceeds a predetermined threshold, the control component controls the exhaust component to start exhausting or increase the exhaust speed, so that the gas in the installation space is exhausted, and the gas outside the installation space flows into the installation space through the ventilation gap, thereby accelerating the fluidity and replacement frequency of the gas in the installation space, so that the heat or water vapor in the installation space can be discharged to the outside of the installation space in time, thereby reducing the temperature or humidity in the installation space, so as to reduce the possibility of product deformation due to heat or damage to consumables due to moisture.

[0011] In some embodiments of the present application, the installation cabinet also includes an installation shell, which is arranged in the installation space and connected to the installation frame.

[0014] In the above embodiment, when air in the installation space flows due to extraction by the exhaust member or other reasons, the air in the installation space can flow into the installation housing through the first communication hole and out through the second communication hole. The sensing end of the sensor is located in the flow path of the airflow, allowing the sensing end of the sensor to promptly contact the airflow flowing from the installation space into the installation housing, thereby enabling timely and accurate detection of the temperature or humidity in the installation space.

[0015] In some embodiments of the present application, the suction member is provided with an exhaust pipe, and the exhaust pipe is connected to an air filter.

[0016] In the above embodiment, the air filter element can filter the gas flowing out of the installation space to reduce the content of harmful substances such as dust in the gas, thereby reducing pollution to the environment.

[0017] In some embodiments of the present application, the installation cabinet further includes an installation rack, which is configured to install consumables of the 3D printing device. The installation rack is disposed in the installation space and connected to the cabinet body.

[0018] In the above embodiment, the mounting bracket is used to wind the consumables so as to store the consumables in the mounting space, thereby reducing the possibility of the consumables being damaged by moisture.

[0019] In some embodiments of the present application, the installation cabinet also includes an installation bracket, which is configured to install consumables of the 3D printing device.

[0057] Reference Figure 3 and Figure 5 The exhaust element 28 is electrically connected to the control element 26. When the temperature data or humidity data detected by the sensing element 27 exceeds a predetermined corresponding threshold value, the control element 26 controls the exhaust element 28 to exhaust air to extract heat or moisture from the installation space 211, thereby reducing the temperature or moisture in the installation space 211.

When the air in the mounting space 211 flows due to extraction by the exhaust element 28 or other reasons, the air in the mounting space 211 can flow into the mounting housing 25 through the first communication hole 251 and out through the second communication hole 251. The sensing end of the sensing element 27 is located in the flow path of the airflow, allowing it to promptly contact the airflow flowing from the mounting space 211 into the mounting housing 25, thereby promptly and accurately detecting the temperature or humidity in the mounting space 211. In other embodiments, the first communicating hole 251 and the second communicating hole 251 may also be respectively provided on two opposite side walls of the mounting housing 25 .

[0059] In other embodiments, the sensor 27 may also be disposed outside the installation housing 25 , as long as the sensor 27 can detect the temperature or humidity data in the installation space 211 .

[0060] In some embodiments, the exhaust element 28 is provided with an exhaust pipe 281, which is connected to an air filter (not shown). The air filter can filter the air flowing out of the installation space 211 to reduce the content of harmful substances such as dust in the air, thereby reducing environmental pollution. In other embodiments, the air filter can be omitted, and the exhaust pipe 281 can be connected to the outside of the room, allowing other air in the installation space 211 to be extracted by the exhaust element 28 and discharged outdoors, thereby reducing the possibility of indoor air pollution.

[0061] In some embodiments, the door panel 214 remains closed while the 3D printing device 100 is printing a product. The light from the fill light 23 is projected onto the print head of the 3D printing device 100, allowing the operator to clearly view the shape of the printed product and adjust the parameters of the 3D printing device 1000 in a timely manner.
