Universal fixture in use for supersound cleaning

Abstract

An ultrasonic cleaning universal fixture for ultrasonic cleaning, consisting of a sliding frame, a fixed frame, four sliding bars, several clips and a water-guiding support rod, the sliding frame and the fixed frame are the same rectangular frame, and The four corners are provided with round holes at the same position, and the upper and lower sides of the two frames are provided with slide grooves, and one end of the slide bar is respectively fixed with the fixed frame, and the slide frame is sleeved on the slide bar through the four corner round holes. The sliding frame is provided with four screw holes corresponding to the positions of the sliding rods, and the two ends of the water guiding support rods are also provided with round holes, which are sleeved on the two sliding rods below, between the sliding frame and the fixed frame, Multiple clips have a "["-shaped structure with a convex back and screw holes at the upper and lower ends. The clips can be freely installed on the sliding frame or the fixed frame by fastening screws. The invention can improve the effect and efficiency of ultrasonic cleaning of the coated film substrate, and improve the quality of the plated thin film.

Description

technical field [0001] The invention relates to glass coating, in particular to a universal fixture for ultrasonic cleaning, which can be used for ultrasonic cleaning of glass coating substrates and ultrasonic cleaning of workpieces in other industries. Background technique [0002] Since the glass coated substrate will leave residues such as polishing powder on the surface after cutting, polishing and many other processing procedures, and will also produce a lot of pollution during transportation. If these surface pollutants are not cleaned It is easy to form microdefects in the film. A large number of experiments now show that the micro-defects formed by impurities on the substrate surface in the film are one of the most important causes of laser damage to the film. If the formation of micro-defects is suppressed, the performance of the film can be greatly improved. The quality of the substrate cleaning directly affects the quality of the coated film, especially for the i...

Problems solved by technology

Manual scrubbing is not only inefficient, but also re-contaminates during scrubbing, which cannot meet the requirements of high-quality coatings; in current ultrasonic cleaning, some lay gauze on the bottom of the ultrasonic cleaner, and directly place the substrate flat on it for ultrasonic cleaning. Not only the number of substrates that can be cleaned each time is limited, but also the upper and lower sides of the substrate are cleaned unevenly, and it is inconvenient to take out the substrate after cleaning

For ultrasonic cleaning using fixtures, different fixtures are generally used for substrates of different specifications, which obviously cannot meet the ever-changing requirements of substrate specifications, resulting in a lot of waste

In addition, when the current fixture is slowly dehydrated with isopropanol in the final step of ultrasonic cleaning, a little cleaning solution will be left on the bottom of the substrate, so that after the cleaning solution evaporates, it will leave marks on the surface of the substrate
