Equipment system and method for automatic cleaning and drying of braces

Abstract

The invention provides an equipment system and method for automatic cleaning and drying of braces. The equipment system comprises: an automatic loading platform for conveying a tool basket holding to-be-cleaned braces to a designated position; an automatic transferring module for grasping the tool basket and transferring the tool basket to each process position; a cleaning module comprising an ultrasonic cleaning module and a bubble cleaning module and used for cleaning the braces to remove residual materials on the surfaces of the braces; a compressed-air water cutting module for removing a large amount of liquid remaining on the surfaces of the braces after cleaning; a hot-air circulation drying module adopting circulating hot-air drying for evaporation of remaining moisture on the surfaces of the braces; a vacuum drying and sterilization module for sterilization of the braces in a vacuum ultraviolet sterilization manner and further evaporation of moisture; and a self-conveying unloading table for conveying the tool basket holding the cleaned and dried braces to a clean room for separation of the braces from the tool basket.

Description

technical field [0001] The invention relates to a braces cleaning device and method, in particular to an equipment system and method for automatic cleaning and drying of braces. Background technique [0002] Invisible orthodontics are usually accomplished with a series of invisible braces. Invisible braces are made of safe elastic transparent polymer materials. The types of polymer materials mainly include polycarbonate (PC), ethylene glycol modified-polyethylene terephthalate (PETG), thermoplastic polyurethane (TPU) )Wait. [0003] Such as figure 1 Shown is the shape and structure of the current invisible braces. The cleaning methods mainly include direct water washing, high-temperature and high-pressure steam washing, blowing washing, etc., and the drying methods mainly include wiping and drying. These methods mainly have the following problems: [0004] 1. Poor versatility of the cleaning method: limited by the existing invisible orthodontic braces production technolo...

AI Technical Summary

Problems solved by technology

[0004] 1. Poor versatility of cleaning methods: limited by the existing invisible orthodontic braces production technology, before the braces are hot-pressed, it is necessary to fill the concave area of ​​the dental mold with paraffin or artificial stone. When the mold and the orthodontics are separated, it is easy to remain on the inner surface of the braces and cause pollution to the braces, so it is necessary to remove the residual substances

Different cleaning methods are used for different residual substances. For example, high-temperature steam is often used to flush paraffin residues. Because the steam temperature is too high, the braces product will be deformed and the product quality will be reduced or the product will be scrapped directly, which brings great difficulty to the manual cleaning operation; artificial Stone residues are often washed with normal temperature and high pressure water

The existing cleaning methods have poor versatility, which complicates the production cleaning process and is not conducive to production site management

[0005] 2. Low cleaning and drying efficiency and high labor intensity: The braces need to be cleaned and dried one by one by the operator, and the cleaning and drying effect needs to be observed from time to time during the cleaning process, which increases the labor intensity of the operator

[0006] 3. The drying method is backward, and there are easy dead corners: At present, manual drying and sanitary cotton cloth (sterilizing) are often used to remove water, because the structure of the braces is relatively complicated, especially there are some dead corners on the inner surface of the braces that cannot be wiped. Cause tiny water droplets to remain

[0007] 4. Poor process stability and frequent rework: At present, the cleaning and drying method is highly dependent on the operator, and the operator may easily cause fatigue when working for a long time, or in order to pursue efficiency when manually cleaning and drying, it is easy to ignore the tiny impurities and small water on the surface of the braces. Beads cannot pass the quality inspection and must be reworked, which greatly wastes manpower and material resources

[0008] 5. Disinfection method: At present, the traditional alcohol wipe disinfection method is used, and the braces are polymer materials that are prone to chemical reactions with alcohol, resulting in whitening of the surface of the braces, affecting the appearance and performance of the braces
