Description

Technical Field

[0001] The invention relates to a 3D printer based on AR technology, belonging to the technical field of printers. Background Art

[0002] For example, a 3D printer disclosed in application number: 201710673897.8 includes a mounting frame, and a printing platform, a printing material conveying device, a hot extrusion device and a displacement device arranged on the mounting frame. The printing platform is placed horizontally, and the hot extrusion device is located above the printing platform. The displacement device is arranged between the printing platform and the hot extrusion device, and drives the printing platform and the hot extrusion device to move relative to each other. The displacement device includes a plane displacement device, and the plane displacement device includes a plane track, a plane displacement seat and a plane driving mechanism. The plane track is fixed to the mounting frame in a horizontal direction and is located above the printing platform. The plane driving mechanism drives the plane displacement seat to slide on the plane track. The hot extrusion device is installed on the plane displacement seat. The plane displacement device also includes a rotation driving mechanism. The rotation driving mechanism drives the printing platform to rotate horizontally. The plane track intersects with the rotation axis of the printing platform. By adopting the above scheme, a 3D printer with reduced printer volume and increased space utilization is provided.

[0003] According to our search and analysis, the existing 3D printers have the following problems: 1. The printing operation structure of the printer in the prior art is an open printing operation structure. The prior art cannot achieve sealing for 3D printing. Compared with the sealed and openable printing structure in the present application, the 3D printing structure in the prior art is less safe. The existing printer may cause operators to be easily injured during operation and may also cause noise transmission and the spread of harmful substances. 2. The prior art cannot realize the operation of sealed display. In this application, an LED lamp arranged inside the sealed body is used to provide backlight for the non-backlight LCD to realize its transparent screen graphic display function, which is not beautiful enough compared with the prior art of this application.

[0004] 3. The printing structures in the prior art are mostly single-door or manual-door structures. Compared with the double-door and automatic-door structures that can be monitored in real time in this application, the printing devices in the prior art are more complicated to operate, have a narrow scope of application, and cannot be monitored in real time; In view of the deficiencies in the above-mentioned prior art, a 3D printer based on AR technology is designed to solve the deficiencies in the above-mentioned prior art.

DETAILED DESCRIPTION

[0019] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is further described in detail below in conjunction with embodiments and drawings, but the implementation manner of the present invention is not limited thereto.

[0020] Compared with the prior art, we believe that the present invention specifically provides four aspects of improved technology, which we list in a general way: Improvement plan 1: Because the existing technology cannot realize the function of sealing for 3D printing, the present invention Figure 1-3 and Figure 5 It can be seen that the reasonable structure of the sealing shell component and the printing component can achieve the function of sealing 3D printing and preventing noise transmission or the dispersion of harmful substances.

[0021] Improvement plan 2: Because the prior art cannot move the printing placement table, it will be difficult to take the printed piece. Figure 1 , Figure 3 and Figure 4 It can be seen that through the reasonable combination of the slide rail assembly and the pulling assembly, the placement table can be manually pulled and moved after the printing is completed, so that the printed work can be easily taken.

[0022] Improvement plan 3: Because the prior art cannot perform the function of automated mobile three-dimensional printing, the present invention Figure 1 , Figure 4 and Figure 6 It can be seen that the function of automated mobile 3D printing can be achieved through the reasonable combination of the mobile rail component, the limited number receiving component and the control component.

[0023] Improvement plan 4: Because the existing technology cannot realize the functions of real-time monitoring and automatic door opening, the present invention Fig. 9 and 10 It can be seen that the internal printing situation can be monitored in real time through the monitoring part. When the printing is completed, the signal can be transmitted to the upper and lower driving parts to drive the door body to rotate to achieve the function of automatic opening. The monitoring can scan the size of the print and automatically analyze the function of opening the large door body or the small door body.

[0024] In summary, the present invention has an integrated improved technical solution, through Figure 1-10 It can be seen that the listed improvement schemes 1-4 are organically combined together to form an integrated device to realize sealed 3D printing. After printing, the printing placement plate can be moved, single-side double doors can be opened, monitored automatic door opening can be realized, and automatic analysis of the size of the printed part can be realized.

[0025] We will discuss and explain the improvement plan 1 listed above in detail: Next we pass Figure 1 , Figure 2 , Figure 3 and Figure 5 It is observed that the 3D printer is formed into a printing device by sealing the body 2 and the door, and the interior of the body 2 is a hollow structure design.

[0026] We will discuss and explain the improvement plan 2 listed above in detail: pass Figure 1 , Figure 3 and Figure 4 It can be seen from the observation that the molding platform 16 at the bottom of the printer body 2 is inserted into the limit rail 20 at the bottom of the body 2 through the sliding block 22 to slide, and the limit rail 20 and the sliding block 22 are moved and displaced through the moving cavity 21 to reduce resistance; pass Figure 1 , Figure 3 and Figure 4 It can be seen from observation that the opening and closing of the opening and closing door 32 is sensed by the opening and closing sensor 24 installed on the outside of the pulling handle 23. When the sensor 24 senses that the opening and closing door 32 is opened, it can give a prompt to the staff. The staff can pull and shift the forming platform 16 through the pulling handle 23 installed on the outer end of the forming platform 16. When moving to the opening, the staff can easily take out the printed product to prevent damage to the product during the taking process.

[0027] We will discuss and explain the improvement plan 3 listed above in detail: pass Figure 1 , Figure 4 and Figure 6It can be seen from observation that the data required for 3D printing is input into the system through the data input control 26. After the input, the system will assign the printing work, and the signal will be received through the motion signal receiving component 18 and the motion signal receiving component 2 19 on the three-dimensional motion module 9. When the door of the body 1 is closed, the equipment can be automatically started for automated mobile printing, and the material can be sprayed and printed by starting the nozzle module 13. The motor 15 is started to drive the lead screw 11 to rotate. During the rotation of the lead screw 11, the height of the three-dimensional motion module 9 can be adjusted, and printing can be performed while adjusting the height. This device can achieve the function of three-dimensional automated 3D printing.

[0028] We will discuss and explain the improvement plan 4 listed above in detail: pass Fig. 9 and 10 It can be observed that during the 3D printing operation, the printing situation inside the body 2 can be monitored in real time through the monitoring 38. During the monitoring process, the size of the printed piece can be monitored and analyzed. When the monitoring 38 analyzes that the printed piece is large, the monitoring 38 transmits a signal to the upper opening and closing driving member 33 and the lower opening and closing driving member 35 to drive the opening and closing door 32 to rotate and open the body 2. When the monitoring 38 monitors that the printed piece is small, the small door on the opening and closing door 32 can be opened. Fig.10 It can be seen that the monitoring 38, the upper opening and closing driving member 33 and the lower opening and closing driving member 35 are electrically connected structures and can perform control operations.
