Problems solved by technology

However, PCB ink raw materials should not be in contact with air, because PCB ink will oxidize and produce precipitated particles after exposure to oxygen, which will affect the quality of PCB ink
However, the existing PCB board inks are mixed after being added to the mixer, and when stirring, it is easy to stir air into it, resulting in precipitation
In addition, each raw material must be used after opening, but due to the different ratios of each raw material, some redundant raw materials need to be discarded, which not only causes waste, but also pollutes the environment

Abstract

The invention discloses a PCB ink mixing and storing device, which comprises a plurality of raw material tanks, wherein pistons are installed in the raw material tanks, the bottoms of the raw materialtanks communicate with feeding pipes, first hydraulic pumps and first electromagnetic valves are installed on the feeding pipes, the feeding pipe is communicated with a discharging pipe, a second hydraulic pump and a second electromagnetic valve are installed on the discharging pipe, the discharging pipe is communicated with a stirring tank of a stirring device, the top of the stirring tank is communicated with a nitrogen tank through a gas pipe, a pressure gauge and a third electromagnetic valve are mounted on the gas pipe, a gas outlet pipe is further mounted at the top of the stirring tankand provided with a one-way valve, and the pressure gauge is in wired or wireless connection with the third electromagnetic valve. According to the invention, contact between ink raw materials and air during ink stirring is effectively isolated, corresponding raw materials can be pumped as required, and oxidation, precipitation and raw material waste of ink are effectively prevented.

Description

technical field [0001] The invention belongs to the field of machinery, and in particular relates to a PCB board ink mixing storage device. Background technique [0002] Printed PCB boards need to be sprayed with PCB ink during the production process. However, the PCB ink raw material should not be in contact with the air, because the PCB ink will oxidize and produce precipitated particles after exposure to oxygen, which will affect the quality of the PCB ink. However, the existing PCB inks are mixed by adding them into a mixer and stirring them, and when stirring, it is easy to stir air into it, resulting in precipitation. In addition, each raw material must be used after opening, but due to the different ratios of each raw material, some redundant raw materials need to be discarded, which not only causes waste, but also pollutes the environment. Contents of the invention [0003] In order to solve the above problems, the present invention discloses a PCB board ink mixi...
