Description

Technical Field

[0001] This utility model relates to the field of 3D printing equipment, and more particularly to a 3D printing device for prototype parts. Background Technology

[0002] In the field of prototype component R&D and small-batch production, 3D printing technology is widely used due to its advantages of flexible molding and short cycle time. Currently, most mainstream prototype component 3D printing equipment adopts a single-station operation mode, which has obvious limitations in its operation process: before printing, the raw material needs to be manually fixed on the printing table at the top of the equipment; after printing, the machine needs to be stopped to remove the finished product, and then the residual printing waste (such as resin residue, powder particles, etc.) on the table needs to be manually cleaned. Finally, new raw material needs to be clamped before the next round of printing can be started. During this process, the equipment is completely idle in the stages of part removal, table cleaning, and material changing, and the repetitive waiting time accounts for a high proportion, which seriously restricts the overall printing efficiency. At the same time, the existing equipment has no station barrier structure. If an attempt is made to improve efficiency by switching between multiple stations, the waste from the printing station can easily fly directly into the waiting station, further aggravating the waste contamination problem, and affecting the subsequent printing accuracy. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a 3D printing device for prototype parts. Through a dual-station design, it can operate simultaneously. While the first station is printing, the second station is used for material loading and changing. Rotating to switch stations starts the new printing process, which greatly reduces equipment idle time and improves efficiency. The first station integrates dust collection to prevent waste from scattering. The barrier structure between the stations protects the cleanliness of the work stations, prevents raw material contamination, and ensures printing accuracy.

[0004] This utility model adopts the following technical solution: a 3D printing device for prototype parts, including a printing device body and a device base. A processing table is rotatably mounted on the upper end of the device base. The processing table is divided into a first station and a second station by a partition plate. The upper end of both the first station and the second station is provided with a clamp for fixing the printing material. A motor is mounted on the bottom of the device base through a motor frame. The output end of the motor is connected to the processing table to drive the processing table to rotate and switch between the first station and the second station. A collection component for collecting printing waste is installed through the processing table. A collection box is provided at the bottom of the device base. An air inlet is provided at the upper end of the device base. The air inlet is connected to the collection box through a pipe. An exhaust fan is installed at the bottom of the collection box. The exhaust fan, collection box, air inlet and collection component cooperate to form a waste collection channel.

[0005] Preferably, the collection assembly includes a fixed collection pipe that is fixedly inserted through the processing table. An inclined head is fixedly connected to the upper end of the fixed collection pipe. Multiple air inlets for sucking up waste chips are opened on the outer side of both the fixed collection pipe and the inclined head. A gooseneck tube is connected to the bottom of the fixed collection pipe. A spring telescopic pin is connected between the outer side of the gooseneck tube and the bottom of the processing table. The spring telescopic pin can drive the gooseneck tube to be in a retracted state by default.

[0006] Preferably, a docking plate is fixedly provided at the bottom of the gooseneck tube and the upper end of the air inlet. The opposite surfaces of the two docking plates are respectively provided with magnetic suction pieces with opposite magnetic properties. The magnetic suction pieces are used to achieve magnetic adsorption docking of the two docking plates, and the spring telescopic pin can be stretched to unfold the gooseneck tube when adsorbed.

[0007] Preferably, an annular rubber gasket is provided on the inner side of the docking disc. The rubber gasket is used to enhance the sealing performance after the two docking discs are docked and to prevent waste leakage.

[0008] Preferably, the air inlets are evenly distributed in multiple directions on the outside of the fixed collection tube and the tilting head to achieve all-round extraction and collection of waste chips from different directions during the printing process.

[0009] Preferably, the output end of the motor is connected to the center position of the processing table to ensure the coaxiality and stability of the processing table when rotating and switching positions, and to avoid the position offset affecting the printing accuracy.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model adopts a dual-station design. When the first station is printing, the second station can simultaneously carry out the preparation work of feeding and clamping new raw materials. There is no need to wait for the first station to complete all processes before starting the preparation operation. When the printing of the first station is completed, the next round of printing can be quickly started by simply rotating and switching stations, which greatly shortens the idle time of the equipment and significantly improves the continuous printing efficiency of prototype parts.

[0011] Based on this, the barrier structure set between the first and second workstations, and the dust collection function integrated in the first and second workstations, can collect the waste generated during the printing process in real time (such as resin debris, powder, etc.), preventing the waste from falling into the equipment or table, reducing the amount of subsequent cleaning work, and preventing the waste from contaminating the printing material, thus providing environmental protection for the printing accuracy of the prototype parts. Based on this, the waste collection components at the top of the first and second workstations can be quickly connected and disconnected from the collection port at the top of the collection box at the bottom of the device base, without affecting the switching between the first and second workstations, while meeting the requirement of effective collection of waste.

[0015] In the description of this utility model, "multiple" means two or more, unless otherwise explicitly specified.

[0016] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Please combine Figure 1-5 The 3D printing device for prototype parts consists of a printing device body (not shown) and a device base 1. A processing table 2 is rotatably mounted on the upper end of the device base 1. The processing table 2 is divided into a first station and a second station by a middle partition plate 3. Both the first station and the second station are equipped with clamps 4 to facilitate product clamping. A motor 5 is mounted on the bottom of the device base 1 via a motor frame 51. The motor 5 drives the processing table 2 on the upper end of the device base 1 to rotate, realizing the switching between the first station and the second station. When the first station is printing, the second station can simultaneously carry out the preparation work of feeding and clamping new raw materials. There is no need to wait for the first station to complete all processes before starting the preparation operation. When the printing of the first station is completed, the next round of printing can be quickly started by simply rotating to switch stations.

[0019] The baffle plate 3 installed on the upper end of the processing table 2 can separate the first and second workstations. When printing is performed at the first workstation, the waste generated will be blocked by the baffle plate 3 to prevent it from entering the second workstation and causing pollution. At the same time, multiple sets of collection components 9 are also installed through the upper end of the first and second workstations. A collection box 6 is installed at the bottom of the device base 1, and an air inlet 8 is installed at the upper end of the device base 1. The air inlets 8 are all connected to the collection box 6 through pipes. An exhaust fan 7 is installed at the bottom of the collection box 6. Thus, the exhaust fan 7, the collection box 6, and the air inlets 8 form a "vacuum cleaner" structure, which can extract the waste generated during the printing process through the air inlets 8.

[0020] In consideration of the switching between the first and second workstations, the connection between the collection component 9 and the air inlet 8 was replaced with a movable connection, which also maintains relative stability during connection. Specifically, the collection component 9 encloses and fixes the fixed collection pipe 91 that runs through the upper end of the processing table 2. An inclined tilting head 92 is fixedly connected to the upper end of the fixed collection pipe 91, and multi-directional air inlets 93 are provided on the outside of the fixed collection pipe 91 and the tilting head 92 to facilitate the comprehensive extraction and collection of waste chips. Meanwhile, a gooseneck tube 94 is provided at the bottom of the fixed collection tube 91. This, along with a spring telescopic pin 96 between the outer side of the gooseneck tube 94 and the bottom of the processing table 2, enables a telescopic connection. The gooseneck tube 94 itself has a telescopic effect, and the spring telescopic pin 96 in its default retracted state can cause the gooseneck tube 94 to be in a retracted state, at which point it cannot dock with the upper end of the air inlet 8. Therefore, docking plates 95 are provided at both the bottom of the gooseneck tube 94 and the upper end of the air inlet 8. The function of the docking plates 95 is that when switching between the first and second work positions, when the gooseneck tube 94 docks with the upper end of the air inlet 8, both docking surfaces are equipped with docking plates 95. The magnetic plates 952 on the docking surfaces of the docking plates 95 have opposite magnetic properties and magnetic attraction, thereby stretching the spring telescopic pin 96 to lower the gooseneck tube 94, thus achieving precise docking between the gooseneck tube 94 and the air inlet 8, and magnetically attracting the temperature. Simultaneously, the annular rubber pad 951 on the inner side of the docking plates 95 increases the sealing effect after connection. At this time, the exhaust fan 7 is activated during the printing process. The waste generated during processing enters through the fixed collection pipe 91 and the air inlet 93 on the outside of the tilting head 92. After passing through the fixed collection pipe 91, the gooseneck pipe 94, and the air inlet 8, it enters the collection box 6 for storage, which facilitates unified collection and subsequent processing.

[0021] Based on this, when switching workstations is required, the two sets of docking plates 95 magnetically adsorbed at the bottom of the gooseneck tube 94 and the top of the air inlet 8 will not affect the rotation of the processing table 2, that is, it will not affect the switching between the first and second workstations. After the switching is completed, the collection component 9 of the corresponding workstation can be reconnected to the air inlet 8 to facilitate subsequent collection, prevent waste from falling into the equipment or table, reduce the workload of subsequent cleaning, and prevent waste from contaminating the printing material, thus providing environmental protection for the printing accuracy of the prototype parts.

[0022] The above embodiments are preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.
