Description

Technical Field

[0001] This utility model relates to the technical field of dental prosthesis surface coating equipment, and in particular to a dental prosthesis surface coating equipment. Background Technology

[0002] In the field of dental prosthodontics, dentures, as important instruments for restoring tooth function and aesthetics, directly impact patients' quality of life. With rising living standards and increasing emphasis on oral health, the demand for dentures is becoming more diversified and focused on higher quality. In terms of materials, dentures have evolved from simple materials like metal and plastic to high-performance materials such as porcelain, all-ceramic, and resin-based composites. Different materials require different surface coatings, driving continuous innovation in denture surface coating equipment. In recent years, rapid technological advancements have provided opportunities for the innovation of denture surface coating equipment. The application of 3D printing technology in denture manufacturing has made denture design and manufacturing more precise and personalized, requiring coating equipment to match with higher precision and flexibility, capable of accurately coating the complex structures of 3D-printed dentures. Advances in materials science have led to the emergence of new denture coating materials, such as nanocomposite materials and smart responsive materials. The application of these new materials necessitates coating equipment with more advanced coating processes and control technologies.

[0003] Currently, dental coating equipment on the market mainly consists of a coating mechanism and a motion mechanism. From the perspective of dental fabrication, the layout and equipment placement in dental production workshops are often quite compact. If the worktable of traditional coating equipment is not easily adjustable in height, it can lead to height mismatches with other supporting equipment. When polished dentures need to be transferred to the coating equipment for surface treatment, if the worktable is too high or too low, operators not only increase their labor intensity during denture handling but are also prone to damage due to improper posture, affecting product quality. Furthermore, during the production of different batches of dentures, adjustments may be needed based on the denture's... Different types and manufacturing processes, along with various auxiliary tooling molds placed on the workbench, can lead to difficulties in achieving the ideal operating height if the workbench height cannot be flexibly adjusted. This makes it difficult to perform coating operations accurately, reducing production efficiency. Furthermore, individual differences among operators are a key factor. Denture makers vary in height, arm length, and operating habits. For shorter operators, an excessively high workbench requires them to frequently tiptoe and use additional auxiliary tools when operating the coating equipment. Prolonged work can easily lead to physical fatigue and make it difficult to operate the spray gun coating tool stably, thus affecting the uniformity and precision of the coating. Utility Model Content
