Problems solved by technology

[0002] When packaging some semiconductor diodes, it is often necessary to clean and dehydrate the workpiece. Most of the existing spray devices use measuring cups to clean and dehydrate multiple workpieces in sequence. Due to the frequent manual operations and the randomness, it is difficult to clean and dehydrate the liquid. Stable and quantitative control, the instability of manual operation also causes serious waste of liquid resources or the impact of product quality, and the greater the frequency, the greater the labor intensity of personnel

Abstract

The invention discloses an automatic quantitative spray machine and a method thereof and relates to spray cleaning equipment. The automatic quantitative spray machine comprises a power supply module and a liquid storage tank, wherein the liquid storage tank is connected with a first flow guide pipeline through a first electromagnetic valve, the control end of the first electromagnetic valve is connected with the first output end of a controller, and a liquid delivery tank is positioned under a pipe opening of the first flow guide pipeline. The liquid delivery tank is connected with a second flow guide pipeline through a second electromagnetic valve, the control end of the second electromagnetic is connected with a second output end of the controller, a photoelectric level sensor is arranged on the liquid delivery tank, the output end of the photoelectric level sensor is connected with the first input end of the controller, and the power supply module supplies power to the first electromagnetic valve, the second electromagnetic valve and the controller. The automatic quantitative spray machine and the method thereof can control liquid quantity in the liquid delivery device, effectively reduce waste of washing liquid, save cleaning cost, achieve automation control, and greatly improve efficiency and reduce work amount.

Description

technical field [0001] The invention relates to a spray cleaning and dehydration equipment, in particular to an automatic quantitative spray machine and method. Background technique [0002] When packaging some semiconductor diodes, it is often necessary to clean and dehydrate the workpiece. Most of the existing spray devices use measuring cups to clean and dehydrate multiple workpieces in sequence. Due to the frequent manual operations and the randomness, it is difficult to clean and dehydrate the liquid. Stable and quantitative control, the instability of manual operation also causes serious waste of liquid resources or the impact of product quality, and the higher the frequency, the greater the labor intensity of personnel. [0003] Therefore, those skilled in the art are devoting themselves to developing an automatic quantitative spraying machine and method for solving the above problems. Contents of the invention [0004] In view of the above-mentioned defects in the...
