2019-2020 Shenzhen weigute DLP prism ultrasonic cleaning machine

  1、 Overview DLP prism the full name of DLP is digital light processing, which means “ in Chinese; Digital optical processing technology;
The core component of DLP projector is DMD, which is fully called digital micromirror device, which means “ Data micromirror device ”, By controlling the opening and deflection of the lens, the image can be displayed

In addition, other core components of DLP include light bulb, optical prism and projection lens
DLP projectors are divided into single-chip, double chip and three chip DMD projectors according to the number of DMDs
In the three piece system, the white light generated by the photo lamp is divided into red, green and blue through the prism

2、 Prism (lens cleaning) &mdash& mdash; Mainly cleaning after coating
Purpose of coating:
1
Beautiful;
2
Reduce reflection and increase the projection rate of the optical system;
3
Improve image definition;
4
Increase added value

Purpose of the cleaning machine: to clean and dry the dirt on the surface of optical glass (PRISM)

Cleaning principle of ultrasonic cleaning machine:
With the improvement of coating technology and the increase of requirements for optical (PRISM) glass, the cleaning after coating becomes more and more important
Although some optical (PRISM) glass has been strictly cleaned for several times, it is bound to be polluted to varying degrees by saliva, fingerprints, dust in the air and other pollutants after processing and transportation in different processes, which will directly affect the quality of the next coating
The decontamination and cleaning of optical (PRISM) glass is generally easy to complete, but in order to achieve high-precision coating technology, the dehydration and drying after cleaning are more critical than decontamination and cleaning

The ultrasonic cleaning machine uses the ultrasonic frequency electrical signal higher than 20kHz, which is converted into mechanical oscillation by the transducer and transmitted into the cleaning solution
The ultrasonic wave radiates forward in the cleaning solution in a dense and alternating manner, making the liquid flow and generating tens of thousands of tiny bubbles
These bubbles form and grow in the negative pressure area formed by the longitudinal propagation of the ultrasonic wave, and close rapidly in the positive pressure area
The formation, growth and rapid closure of these bubbles are called cavitation phenomenon
In the cavitation phenomenon, the closure of these bubbles forms an instantaneous high pressure of 1000 atmospheres
The continuous instantaneous high pressure is like a series of small “ Explosion ”, Continuously bombard the surface of the object, so that the dirt on the surface of the object and in the gap can peel off quickly, so as to achieve a rapid cleaning effect

Our vgt-1407fh optical ultrasonic cleaning machine after coating aims at “ Prism ” Cleaning of:
  Vgt-1407fh is an optical ultrasonic cleaning machine after coating
The equipment has 14 functional tanks, equipped with soaking system, filtration circulation system, automatic constant temperature system, throwing system, ultrasonic cleaning system, slow pulling dehydration system, hot air drying system, closed cylinder door system, exhaust device, etc
The equipment is washed with environment-friendly water solvent and rinsed with pure water
It is an environment-friendly cleaning machine

Analyze the partial structure of vgt-1407fh optical ultrasonic cleaning machine after coating:
Structure of soaking system:
1
One side overflow port is set, and the overflow groove is 35mm wide
The dirt floating on the surface of the tank is directly discharged through the overflow port;
2
Set municipal water inlet;
3
Drain valve is set at the bottom of each tank;
4
Throw is set outside the groove

Filter circulation system:
1
A removable filter screen is added in front of the pump, and a filter is installed behind the pump;
2
A water pressure gauge is installed in front of the filter, indicating that the filter needs to be replaced or cleaned

Slow pull dehydration system:
High precision surface cleaning requires not only reasonable cleaning process and configuration, but also good dehydration effect
If there are any dirt or water spots on the surface of the workpiece, the coating will eventually fail
High temperature slow drawing dehydration of high-purity water is an essential process for high-precision cleaning of glass products
It can effectively form a uniform hot pure water film, quickly lose surface moisture, achieve high-definition surface cleanliness, and lay a favorable foundation for subsequent drying

Hot air drying trough: each drying trough is equipped with a set of air cylinders, which drive the tempered glass to move together to form a sealing cover

Throwing system: the workpiece is evenly thrown during the cleaning process, which can increase the friction between the workpiece and the liquid, help the surface dirt fall off quickly, and improve the cleaning effect
