Description

Technical Field

[0001] The present invention relates to the technical field of denture processing, and in particular to a denture 3D printing molding device and a denture processing method. Background Art

[0002] Denture 3D printing molding equipment is an advanced equipment specially used for manufacturing dentures. It is based on 3D printing technology and can manufacture the required denture processing equipment according to the specific conditions of the patient's oral cavity.

[0003] In the prior art, most denture 3D printing molding equipment is composed of a molding system, a feeding system, a motion system and a control system. The working principle of denture 3D printing molding equipment is mostly based on a three-dimensional digital model, and the denture is manufactured by stacking materials layer by layer. Before printing, it is necessary to use an oral scanning device to obtain accurate data of the patient's oral cavity and generate a three-dimensional digital model. After that, the model data is imported into the 3D printing equipment. The equipment will solidify or bond the liquid photosensitive resin, thermoplastic plastic and other printing materials layer by layer according to the preset program to finally form a denture. At present, denture 3D printing molding equipment has been widely used in dental clinics, oral hospitals, denture processing plants and other places.

[0004] In actual use, unlike traditional 3D printing technology, denture 3D printing molding equipment not only has strict requirements on the processing environment when processing dentures to prevent impurities from being mixed into the dentures during the processing, but also has high requirements on the molding temperature of the dentures. However, the denture 3D printing molding equipment in the existing technology, when processing dentures, mostly prints the dentures directly on the printing carrier. When printing the dentures, it is difficult to preheat the printed denture materials. When there is a temperature difference on the surface of the denture material after printing, it may cause deformation of the material, internal stress concentration and other problems, affecting the dimensional accuracy and mechanical properties of the denture.

[0015] A denture processing method, using the above-mentioned denture 3D printing molding device, comprises the following steps: Step 1, 3D printing, when printing the denture, by starting the positioning motors on the X-axis positioning assembly, the Z-axis positioning assembly and the Y-axis positioning assembly, the output end of the positioning motor drives the positioning worm to rotate, the rotation of the positioning worm drives the positioning worm wheel to rotate, and the rotation of the positioning worm wheel drives the positioning ball nut group to move, when the positioning ball nut group rotates, the positioning ball nut group moves on the positioning screw, and the movement of the positioning ball nut group simultaneously drives the positioning frame to move, and the movement of the positioning frame drives the positioning box to move, under the movement of the positioning box in the X-axis positioning assembly, the Z-axis positioning assembly and the Y-axis positioning assembly, the molding system is driven to move to any position on the thermal printing base plate, and the denture can be 3D printed through the cooperation of the feeding system and the molding system; Step 2: preheating the denture. During the 3D printing of the denture, start the industrial hot air blower so that the hot air blown out of the industrial hot air blower enters the hollow loading plate through the gas delivery elbow and the gas delivery telescopic pipe.

[0017] 2. The present invention can preheat the hollow carrier plate by adjusting the temperature of the industrial hot air blower when printing the denture, and the hot air blown out through the exhaust elbow can fully preheat the denture. After the denture is printed, the industrial hot air blower can be turned off to cool down the denture as a whole, which can effectively avoid the problem of deformation of the denture due to temperature difference. 3. In the present invention, when printing the denture, the sealed printing box can not only effectively prevent foreign matter from entering the printing box and ensure the cleanliness of the denture, but also when taking out the denture, the denture can be moved to one side of the printing box, which is convenient for medical staff to take out the material, greatly reducing the difficulty of taking out the material, and the convenient taking out of the material can effectively prevent the problem of denture breakage caused by some reasons during the taking out process.

9. The denture 3D printing device according to claim 8, characterized in that: A viewing through hole is also provided on one side of the printing box (1), and a viewing window (25) is sealed in the viewing through hole.

10. A denture processing method, using the denture 3D printing molding device according to claim 9, characterized in that: The following steps are involved: S1. 3D printing. When printing a denture, the positioning motor (21) on the X-axis positioning assembly, the Z-axis positioning assembly, and the Y-axis positioning assembly is started. The output end of the positioning motor (21) drives the positioning worm (22) to rotate. The rotation of the positioning worm (22) drives the positioning worm wheel (23) to rotate. The rotation of the positioning worm wheel (23) drives the positioning ball nut assembly (19) to move. When the positioning ball nut assembly (19) rotates, the positioning ball nut assembly (19) ) moves on the positioning screw (18), and the movement of the positioning ball nut group (19) drives the positioning frame (20) to move at the same time, and the movement of the positioning frame (20) drives the positioning box (17) to move. Under the movement of the positioning box (17) in the X-axis positioning assembly, the Z-axis positioning assembly and the Y-axis positioning assembly, the molding system is driven to move to any position on the thermal conductive printing base plate (10). Through the cooperation of the feeding system and the molding system, the denture can be 3D printed; S2, preheating the denture. During the process of 3D printing the denture, the industrial hot air blower (11) is started, so that the hot air blown out of the industrial hot air blower (11) enters the hollow material carrier plate (4) through the gas delivery elbow (14) and the gas delivery telescopic pipe (13). While preheating the hollow material carrier plate (4), the gas in the hollow material carrier plate (4) is blown toward the denture on the thermal printing base plate (10) through the exhaust elbow (15), so as to preheat the denture; S3, denture material removal. After the denture is printed, the material removal motor (9) is started, and the output end of the material removal motor (9) drives the material removal screw (6) to rotate. When the material removal screw (6) rotates, it drives the material removal ball nut group (7) to move. The movement of the material removal ball nut group (7) drives the material removal adjustment block (8) to move. The movement of the material removal adjustment block (8) drives the hollow material loading plate (4) to slide toward one side of the processing box door (2). When the hollow material loading plate (4) slides, the hollow material loading plate (4) drives the material removal baffle plate (5) to move, so that the material removal baffle plate (5) is separated from the processing box door (2). At the same time, the hollow material loading plate (4) drives the denture on the thermal conductive printing base plate (10) to move to one side of the printing box (1), so that the medical staff can take the denture material.
