The automatic stencil cleaning machine is a cabinet type vertical cleaning machine. The stainless steel looks beautiful and generous, can clean the screen (copper plate) with solder paste or red glue, and will not cause damage to the stencil. . Because the cleaning machine technology used in the automatic screen cleaning machine is ultrasonic cleaning, in addition, a sprinkler device is added, which can effectively clean the solder paste on the screen plate under the dual action of the ultrasonic wave and the spray system. And it will automatically dry, will not leave traces of water stains on the screen, use a white and clean cloth to gently wipe the screen, do not see any residue or dust on the white cloth, which can also explain that cleaning The cleaning effect of the machine is worthy of our trust!

The stencil cleaning machine has three cleaning processes, namely cleaning of the cleaning solution, rinsing of the ultrasonic wave, and water removal by the wind cutting. The first solvent cleaning process uses the splint assembled in the stencil cleaning machine to clamp the stencil and automatically control it so that the stencil can be pulled back and forth to ensure that each position can be sprayed in place and the cleaning solvent is in place. Under the action of ultrasonic waves, tens of thousands of cavitation bubbles are generated. As the small bubbles that are formed continuously blast in a positive pressure environment, the bubbles after blasting will form an impact force, that is, we let go and feel that there will be numerous needles. I feel that if the frequency is higher, I always feel that my palm can be penetrated, so don't try it easily. The force generated by the tens of thousands of bubble bursts can quickly shoot down the solder paste glue stuck on the screen, plus a high-pressure spray system, it can be said that the whole network cleaning without dead ends.

The second cleaning process is ultrasonic rinsing. Since the first ultrasonic cleaning has achieved a good cleaning effect, after all, a chemical cleaning agent is used, so the screen needs to be rinsed. The medium used in this process is Water, and the frequency of the ultrasonic wave is 40Khz, and the liquid temperature is about 40 degrees Celsius. After the rinsing is completed, the stencil cleaning machine automatically performs the third process, namely air-cut drying, which can dry the water stain of the second process. In fact, the operation of the entire cleaning process is also simple, only the worker needs to put the screen on the robot arm of the screen cleaning machine, and the pneumatic button is pulled down, the robot of the equipment will send the screen to the fixed station, according to the engineer. The fixed station process completes the cleaning of each step and finally goes to the in-situ operation to complete the cleaning process.

The solvent used in the stencil cleaner is a water-based solvent, which has many advantages over organic solvents. We know that organic solvents can not be reused, while water-based solvents can be reused, which can save solvent costs; organic solvents are a volatile liquid, while water-based solvents are not easily volatilized; In terms of quantity, the organic solvent has more ions than the water-based solvent. If the organic solvent is used for cleaning, it is equivalent to about 8 to 10 yuan for each screen of the manufacturer. If the water-based solvent is used, the cost of washing a screen can be reduced by 50%.
