Description

Technical Field

[0001] The invention relates to the technical field of dental braces production, in particular to a dental braces laminating machine. Background Art

[0002] In the field of modern oral medicine, with the improvement of people's living standards and the increasing attention paid to oral health and aesthetics, the demand for tooth correction and restoration is growing. As a key instrument in the process of tooth correction and restoration, the production quality and efficiency of braces directly affect the treatment effect and patient experience. One of the core links in the production of braces is the dental mold film, which is to use specific equipment to fit the film tightly on the dental mold to form a braces model that accurately matches the shape of the patient's teeth.

[0003] At present, the technical level of dental braces lamination equipment varies, and there are many problems that need to be solved. In the domestic market, small dental laminators mainly rely on imports, such as German Schor laminators and Acter laminators. Although these imported equipment can meet basic lamination needs to a certain extent, they have significant limitations. First, the cost of imported equipment is high, and the purchase price is often several times the expected price of similar domestic equipment. This makes many dental clinics and small medical institutions face huge economic pressure when purchasing equipment, which limits the widespread popularization of advanced lamination technology. Secondly, most of these equipment require manual operation to complete each step, from the placement and heating of the membrane to the lamination, each link relies on manual operation, which is not only inefficient and difficult to meet the needs of large-scale production, but also the inconsistency of manual operation can easily lead to fluctuations in product quality, and it is impossible to ensure that the lamination effect of each brace can reach the ideal state. In addition, the accessories and maintenance costs of imported equipment are also high. Once the equipment fails, the maintenance cycle is long and expensive, which further increases the cost of use and affects the normal use of the equipment and the continuity of production.

[0004] From a technical perspective, existing laminating equipment has obvious deficiencies in heating control and automation. Some equipment is unable to accurately and real-time monitor and regulate the heating temperature of the diaphragm, resulting in uneven heating of the diaphragm. During the laminating process, the degree of fit between the diaphragm and the dental mold at different positions is inconsistent, affecting the quality and precision of the braces. For example, if the heating temperature is too high, the diaphragm may melt excessively, resulting in uneven thickness of the braces; if the heating temperature is too low, the diaphragm will not be able to fully fit the dental mold, resulting in gaps or looseness. In terms of automation, although some equipment has certain automation functions, the overall degree of automation is still low, and it is impossible to achieve full-process automation from diaphragm loading, heating, laminating to unloading. A lot of manual auxiliary work is still required, which not only increases labor costs, but also makes it easy for human errors to occur, reducing production efficiency and product quality stability.

[0005] In addition, existing film pressing equipment also has defects in dental model information management. Most equipment lacks effective dental model information recording and storage functions and cannot accurately record and trace the dental model information of each film pressing finished product. During large-scale production and quality control processes, this defect makes it difficult to effectively monitor and manage product quality, unable to promptly discover and solve problems that occur during the production process, and is not conducive to the optimization of production processes and the improvement of product quality.

[0006] In summary, existing dental brace film pressing equipment has many deficiencies in terms of cost, automation level, heating control, and information management, severely restricting the development of the dental brace production industry. Therefore, it is of great practical significance to develop a dental brace film pressing machine and HMI system with low cost, high automation level, precise heating control, and dental model information management functions, which can fill the domestic market gap and meet the urgent needs of the oral medical industry for efficient and high-quality dental brace manufacturing equipment.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The dental braces laminating machine realizes the full-process automation operation from grabbing, transporting, heating, laminating to unloading of the diaphragm through the transfer mechanism, lifting mechanism, rotating mechanism and heating mechanism. The transfer structure uses the vacuum emitter and the suction cup assembly to quickly and accurately absorb and grab the diaphragm, and uses the conveyor belt and the lifting cylinder to efficiently transport it to the designated position, saving the time and energy of manual loading. At the rotating station, the dividing plate is driven by the motor to rotate accurately, and the diaphragm can be quickly transferred to different processing stations, so that the entire production process is closely connected and efficiently operated. Compared with the traditional manually operated laminating machine, the present invention can shorten the production cycle of a single dental brace, improve production efficiency, significantly reduce labor costs, and effectively meet the urgent needs of large-scale production.

[0019] 2. The braces laminator is equipped with a temperature sensor in the heating mechanism, which can monitor the temperature of the heating lamp and the diaphragm in real time, and transmit the data to the HMI system in real time. The HMI system accurately controls the heating time of the heating lamp and the action of the rotating cylinder according to the preset temperature threshold. During the heating process, when the temperature approaches or reaches the set value, the system quickly controls the heating lamp to stop heating and make it leave the diaphragm, ensuring that the heating temperature of the diaphragm is always kept within the ideal range, avoiding problems such as excessive melting of the diaphragm and loose fitting due to excessively high or low temperature. Each diaphragm can obtain a consistent and stable heating effect, thereby making the quality of the finished laminating product more stable and reliable, effectively improving the product qualification rate, reducing the production of defective products, and providing a solid guarantee for the quality of braces production.

[0020] 3. After the film pressing is completed, the barcode reader of this dental appliance film pressing machine can accurately read the dental model information on the film and store this information in the system. The stored information includes key data such as the patient's tooth characteristics and the dental appliance model, providing strong support for subsequent quality inspection, traceability, and optimization of the production process. In the quality inspection link, the staff can quickly screen out unqualified products based on the information recorded by the barcode reader and trace back to the relevant parameters and links in the production process, so as to timely discover problems and take targeted improvement measures.

The runner 3054 is rotatably connected to the positioning rod 3053 through a bearing, and the lower end of the positioning rod 3053 slides in the guiding chute 3055.

[0046] The driving device inside the diaphragm placement table 304 drives the rotating disk 3051 to rotate, thereby driving the runner 3054 and the positioning rod 3053 to revolve. When the positioning rod 3053 revolves, it is guided by the guiding chute 3055, causing the positioning rod 3053 to move towards the center or move outwards in the first chute 3052.

[0057] The automatic mode includes the following steps:

[0058] S1: The HMI system controls the transfer mechanism 2 to adsorb and grab the film and automatically transport it to the film pressing station;

[0059] S2: The first motor drives the indexing plate 404 to rotate clockwise, thereby driving the film on the film pressing station to rotate clockwise and transferring the film to directly above the film pressing plate 803;

[0060] S3: The pressing cylinder 801 expands and contracts to drive the film pressing plate 803 to move downward to press and fix the film;

[0061] S4: The rotary cylinder 502 drives the heating lamp cover 504 to rotate clockwise, thereby driving the heating lamp tube 505 to rotate clockwise to directly above the film pressing plate 803 to heat the film. The temperature sensor 506 detects the temperature around the heating lamp tube 505 and transmits the data to the HMI system. When the temperature reaches the threshold, the HMI system controls the rotary cylinder 502 to drive the heating lamp cover 504 to rotate counterclockwise and leave directly above the film pressing plate 803, and at the same time turns off the heating lamp tube 505 to stop heating;

[0062] S5: The lifting cylinder 601 drives the protective air hood 602 to press downwards, blow air and maintain pressure on the diaphragm that has completed heating, so that the diaphragm tightly wraps and adheres to the dental mold.

[0063] S6: The code reader 9 reads the code of the pressed diaphragm, records the dental mold information and stores it.

[0064] Working principle: When using this dental mold laminating machine, first, the driving device inside the diaphragm placement table 304 drives the rotating disk 3051 to rotate, and then drives the runner 3054 and the positioning rod 3053 to revolve. When the positioning rod 3053 revolves, it is guided by the guiding chute 3055, so that the positioning rod 3053 moves towards the center or moves outwards in the first chute 3052. While limiting and fixing the diaphragm on the rotating disk 3051, the diaphragm is positioned directly below the center of the suction cup 205, which is convenient for accurate picking. The forward and reverse motor 306 drives the screw assembly 303 to rotate, and the screw assembly 303 rotates to drive the diaphragm placement table 304 to move up and down; so that the suction cup 205 approaches the diaphragm on the rotating disk 3051, and the vacuum emitter 206 and the suction cup 205 perform vacuum extraction to adsorb the diaphragm on the rotating disk 3051. The conveyor belt 202 rotates to drive the lifting cylinder 204 to move left and right, and then drives the suction cup 205 to move left and right to transport the diaphragm, achieving the effect of automatic feeding. The laminating station limits the diaphragm. The first motor drives the indexing disk 404 to rotate, so that the diaphragm rotates to below the diaphragm pressing plate 803. The pressing cylinder 801 expands and contracts to drive the diaphragm pressing plate 803 to move downwards to press and fix the diaphragm. The heating lamp tube 505 heats the diaphragm, and the temperature sensor 506 monitors the temperature of the heating lamp tube 505 and the diaphragm in real time, accurately controlling the heating condition of the diaphragm and improving the laminating effect of the diaphragm. The lifting cylinder 601 drives the protective air hood 602 to press downwards, blow air and maintain pressure on the diaphragm that has completed heating, so that the diaphragm tightly wraps and adheres to the dental mold, and cools down the diaphragm on the laminating station through the exhaust hole 7032.
