Description

Technical Field

[0001] This utility model belongs to the technical field of dental prosthesis manufacturing equipment, and specifically relates to a rotary transfer mechanism for dental prosthesis materials. Background Technology

[0002] In the dental prosthesis manufacturing industry, efficient and stable material transfer is crucial for ensuring production efficiency and product quality. Currently, dental prosthesis material transfer systems generally employ traditional linear transfer methods, meaning that after material is processed at a workstation, it must completely exit the work area until the next material enters the workstation before processing can begin. This transfer method has significant technical drawbacks and has severely restricted the production efficiency and product quality of the dental prosthesis manufacturing industry.

[0003] Specifically, traditional dental prosthesis material handling systems typically include a work station and a waiting station, through which materials are processed sequentially. After the first material completes processing at the work station, the system waits for it to completely exit before the next material can enter and begin processing. This process takes time, resulting in significant waiting time during material handling. In high-frequency material handling, this accumulated waiting time significantly reduces overall production efficiency. For example, on a production line requiring the handling of five materials per minute, the efficiency loss due to waiting time in a traditional system can exceed 15%, severely impacting the production line's capacity utilization.

[0004] Furthermore, in traditional systems, the workstation remains open during material switching, making effective sealing and dust prevention impossible. The denture manufacturing process generates significant amounts of dust, which not only affects material cleanliness, leading to lower product yields, but also poses health risks to operators and contaminates production equipment, increasing maintenance costs. Dust in the work environment has become a pressing technical challenge for the denture manufacturing industry.

[0005] Existing dust control measures are mostly simple physical barriers that cannot achieve dynamic sealing during material transfer. For example, some systems use movable baffles at the work station, but these baffles need to be opened manually or automatically when materials enter or exit, making them unable to synchronize with the material transfer process and resulting in poor dust control. Furthermore, existing systems expose the work area for extended periods during material changes, leading to significant dust emissions, which fails to meet the high cleanliness requirements of modern dental prosthesis manufacturing. Utility Model Content

[0006] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a rotary transfer mechanism for dental prosthesis materials. It adopts a rotary synchronous transfer structure for dental prosthesis material platform and a dynamic dustproof design. By synchronously switching the material platform and the dynamic sealed working area, it can eliminate material transfer waiting time and achieve the effect of dust control in the working environment.

[0007] To solve the above problems, the technical solution adopted by this utility model is as follows: a rotary transfer mechanism for denture materials, comprising: a base, a slide rail provided on the upper end surface of the base, and a first motor provided at one end of the base;

[0008] A connecting mechanism, comprising a slider and a first fixed plate, wherein the slider is slidably connected to the slide rail and the slider is fixed below the first fixed plate;

[0009] A rotating mechanism is fixed above the connecting mechanism. The rotating mechanism is provided with a support frame, a rotating connecting device, and a rotating disk. The support frame is fixed above the first fixed plate. A second motor is provided on the side of the support frame. The rotating connecting device is fixed to the upper end of the support frame. The rotating disk is fixed to the rotating connecting device.

[0010] The front and rear module mechanism includes a third fixed plate and a first module and a second module fixed to both ends of the third fixed plate. The third fixed plate is connected to the rotating disk. When the rotating disk rotates, it can drive the fixed plate to rotate back and forth, so that the first module and the second module can alternately enter the working area.

[0011] Compared to existing technologies, the advantages of this invention are as follows: This application completely eliminates the waiting time in traditional material handling systems through a rotary synchronous transfer method. In traditional systems, there is a certain time interval between the exit of material from one workstation and the entry of the next. This application, by setting up front and rear modules and a rotating mechanism, allows the front and rear modules to rotate 180 degrees under the action of the rotating mechanism, achieving seamless switching between the first and second material platforms and eliminating the waiting time in traditional denture transfer systems. During the material switching process, dustproof doors are installed in the work area to ensure complete sealing of the work area during material transfer. More importantly, this application reduces equipment downtime without requiring complex control systems and frequent mechanical adjustments, bringing significant economic benefits to denture manufacturing companies. Simultaneously, the improved working environment protects the health of operators and reduces the incidence of occupational diseases.

[0012] In the aforementioned transmission mechanism, the slide rail is a linear guide rail, and the slider can drive the front and rear modules to move linearly along the linear guide rail.

[0013] In the aforementioned transmission mechanism, the first fixed plate has grooves on both sides, and a vertical support plate is fixed inside the grooves. The vertical support plate is used to connect the connecting mechanism and the rotating mechanism.

[0014] In the aforementioned transmission mechanism, the rotating mechanism has connecting plates on the left and right sides. The lower end face of the connecting plate is fixed to the vertical support plate, and the upper end face of the connecting plate is fixed to the lower end face of the rotating connecting device.

[0015] In the aforementioned transmission mechanism, a clearance hole is provided between the support frame and the vertical support plate.

[0016] In the aforementioned transmission mechanism, the side of the rotary connecting device is provided with a first positioning mechanism, which is fixed below the third fixing plate.

[0017] The aforementioned transfer mechanism includes a first material platform on the first module and a second material platform on the second module. The first material platform can move up and down along the first module, and the second material platform can move up and down along the second module.

[0018] In the aforementioned transmission mechanism, a second positioning mechanism is provided at the front and rear of the slide rail, and the second positioning mechanism is fixed to the side of the slide rail.

[0019] The aforementioned transfer mechanism includes a dustproof door in the working area. When the dustproof door is opened, the front and rear module mechanisms can enter or exit sequentially.

[0020] The aforementioned transfer mechanism has a first material platform and a second material platform that are circular. Attached Figure Description

Detailed Implementation

[0024] The embodiments of this utility model are described in detail below, with reference to Figures 1 to 2 This utility model provides a rotary transfer mechanism for dental prosthesis materials, including: a base 100, a connecting mechanism 200, a rotating mechanism 300, and a front and rear module mechanism 400. The upper surface of the base 100 is provided with a slide rail 110, and one end of the base 100 is provided with a first motor 120. The connecting mechanism 200 includes a slider 210 and a first fixing plate 220. The slider 210 is slidably connected to the slide rail 110 and fixed below the first fixing plate 220. The rotating mechanism 300 is fixed above the connecting mechanism 200 and is provided with a support frame 310, a rotating connecting device 320, and... The rotating disk 330 and the support frame 310 are fixed above the first fixed plate 220. The side of the support frame 310 is provided with a second motor 311. The rotating connecting device 320 is fixed to the upper end of the support frame 310, and the rotating disk 330 is fixed on the rotating connecting device 320. The front and rear module mechanism 400 includes a third fixed plate 410 and a first module 420 and a second module 430 fixed to both ends of the third fixed plate 410. The third fixed plate 410 is connected to the rotating disk 330. When the rotating disk 330 rotates, it can drive the fixed plate 410 to rotate back and forth, so that the first module 420 and the second module 430 can alternately enter the working area.

[0025] This application completely eliminates the waiting time in traditional material handling systems through a rotary synchronous transfer method. In traditional systems, there is a certain time interval between the exit of material from one workstation and the entry of the next. However, this application, by setting up front and rear module mechanisms 400 and a rotating mechanism 300, allows the front and rear module mechanism 400 to rotate 180 degrees under the action of the rotating mechanism 300, achieving seamless switching between the first material platform 421 and the second material platform 431, eliminating the waiting time in traditional denture transfer systems. During the material switching process, this application ensures complete sealing of the work area by installing dustproof doors. More importantly, this application reduces equipment downtime without the need for complex control systems and frequent mechanical adjustments, bringing significant economic benefits to denture manufacturing enterprises. At the same time, due to the improved working environment, the health of operators is protected, reducing the incidence of occupational diseases.

[0026] Furthermore, the base 100, serving as the basic frame, provides stable moving support for the front and rear module mechanisms 400 through the sliding connection between the slide rail 110 and the slider 210. The combination of the first fixed plate 220 and the vertical support plate 230 of the connecting mechanism 200 ensures the stability of the rotating mechanism 300 and avoids structural deformation or vibration caused by rotation. The rotating disk 330 in the rotating mechanism 300 is driven by the second motor 311, which drives the third fixed plate 410 to rotate back and forth, allowing the first module 420 and the second module 430 to alternately enter the working area, completely eliminating the waiting time in traditional linear transmission. At the same time, the linkage design between the rotating disk 330 and the front and rear module mechanisms 400 allows the dust door to open and close synchronously with material switching, dynamically sealing the working area. Furthermore, the slide rail 110 proposed in this application is a linear guide rail, and the slider 210 can drive the front and rear module mechanisms 400 to move linearly along the linear guide rail. The high rigidity and smoothness of the linear guide ensure that the slider 210 moves along a predetermined trajectory during movement, reducing module jamming or positioning errors caused by deviation in the sliding direction. For example, in the material transfer of dentures, the first module 420 and the second module 430 need to frequently travel between the work area and the waiting area. Traditional guide rails 110 are prone to module position deviation due to manufacturing tolerances or wear during use. However, the linear guide rail in this solution, through the precise cooperation of the ball bearings or slider 210, controls the movement error within a certain range, significantly improving the transfer accuracy.

[0027] Furthermore, referring to Figure 1 The first fixing plate 220 proposed in this application has grooves 221 on both sides. A vertical support plate 230 is fixed inside the grooves 221. The vertical support plate 230 is used for connection. Furthermore, the vertical support of the vertical support plate 230 effectively suppresses the lateral swaying of the connecting mechanism 200, ensuring that the rotation axis of the rotating disk 330 is always in the center position, preventing the material platform from tilting or material from falling due to eccentric rotation. This design also optimizes the spatial layout, making the assembly of the rotating mechanism 300 and the connecting mechanism 200 more compact and reducing the overall space occupied. The groove 221 structure provides an embedded installation space for the vertical support plate 230, maximizing the contact area of ​​the connection part, thereby dispersing the lateral force generated during rotation and avoiding structural fatigue fracture caused by local stress concentration. Further, referring to… Figure 1 and Figure 2The rotating mechanism 300 has connecting plates 340 on both sides. The lower end of the connecting plate 340 is fixed to the vertical support plate 230, and the upper end of the connecting plate 340 is fixed to the lower end of the rotating connecting device 320. The lower end of the connecting plate 340 is welded or bolted to the vertical support plate 230, and the upper end is tightly fitted to the rotating connecting device 320, forming a triangular support structure, which greatly enhances the torsional resistance of the rotating mechanism 300. For example, in the material transfer of dentures, the rotating disk 330 needs to support a relatively heavy material platform (such as a tray for denture semi-finished products). Traditional rotating mechanisms 300 are prone to structural deformation due to weak connections. However, this solution, through the reinforcement design of the double-sided connecting plates 340, improves the load-bearing capacity of the rotating mechanism 300, enabling it to stably support materials of a certain weight.

[0028] Furthermore, referring to Figure 2 In this application, a clearance hole 500 is provided between the support frame 310 and the vertical support plate 230. The clearance hole 500 provides sufficient space for the rotating shaft of the rotary connecting device 320, preventing physical collision between the rotating disk 330 and the support frame 310 during rotation. Simultaneously, the open structure of the clearance hole 500 facilitates the injection and maintenance of lubricant, reducing the maintenance difficulty of the rotating mechanism 300. Furthermore, referring to… Figure 1 The rotating connecting device 320 proposed in this application has a first positioning mechanism 321 on its side, which is fixed below the third fixing plate 410. The first positioning mechanism 321 cooperates with the positioning hole of the third fixing plate 410 to ensure that the rotating disk 330 can accurately reset after rotating 180 degrees each time. For example, in the transfer of denture materials, if the positioning deviation of the rotating disk 330 exceeds a certain value, it may cause misalignment of the material platforms of the first module 420 and the second module 430, resulting in material collision or jamming. This solution, through the precise locking of the first positioning mechanism 321, controls the positioning error of the rotating disk 330 within a certain range, ensuring seamless switching of the material platform. In addition, the automatic locking function of the positioning mechanism 321 avoids operational errors caused by manual adjustment and improves the degree of automation.

[0029] Furthermore, the first module 420 of this application is provided with a first material platform 421, and the second module 430 is provided with a second material platform 431. The first material platform 421 can be raised and lowered along the first module 420, and the second material platform 431 can be raised and lowered along the second module 430. The first material platform 421 and the second material platform 431 can be used to place denture materials. Of course, this application does not limit the specific structure of the lifting platform. Preferably, the lifting function mentioned in this application can be realized by a hydraulic cylinder or an electric push rod. Further, referring to... Figure 2The slide rail 110 mentioned in this application is provided with a second positioning mechanism 111 at the front and rear, and the second positioning mechanism 111 is fixed to the side of the slide rail 110. The second positioning mechanism 111 on the side of the slide rail 110 solves the positioning deviation problem caused by wear of the slide rail 110 or loosening of the slider 210 during the movement of the front and rear module mechanisms 400. The second positioning mechanism 111 typically includes a magnetic sensor or a mechanical limit block, which monitors the position of the slider 210 in real time and feeds it back to the control system to ensure the accuracy of module movement.

[0030] Furthermore, the work area mentioned in this application is equipped with a dustproof door. When the dustproof door is opened, the front and rear module mechanisms 400 can enter or exit sequentially. The dustproof door design in the work area solves the product quality problems caused by dust contamination in traditional transfer systems. The dustproof door is pneumatically or electrically driven and opens and closes synchronously with the movement of the front and rear module mechanisms 400, ensuring a completely sealed work area during material switching. Moreover, this application does not limit the specific shape of the first material platform 421 and the second material platform 431. Preferably, the first material platform 421 and the second material platform 431 are circular. The symmetrical structure of the circular platform ensures a uniform distribution of the center of gravity, balanced force during rotation, and reduces material displacement caused by centrifugal force. More importantly, the circular material platform can better match the denture material, preventing denture dislodgement caused by shearing forces generated during material rotation.
