How to correctly deal with the metal surface problem of the dividing machine?

Dividing machine usually refers to PCB dividing machine, that is, circuit board dividing machine. Cutting machine is widely used in electronic product manufacturing industry; Because the traditional manual folding method will produce strong stress and seriously affect the product quality, the manual folding has been basically replaced by machine splitting.

Chemical treatment can be carried out after passing through the diaphragm: first, the acidic or alkaline solution is used to react with the oxide and oil stain on the workpiece surface, so as to dissolve it in the acidic or alkaline solution. The purpose of removing surface rust is to remove scale and oil stain.

The chemical treatment is carried out according to the flatness of sheet parts, but the disadvantage is that if the time is not controlled properly, even adding corrosion inhibitor will lead to excessive corrosion of steel.

Mechanical disposal methods: first, including shot blasting and shot blasting. Shot blasting is a method that uses centripetal force to accelerate the shot and project it onto the workpiece to stop rust removal and solidification.

However, the sensitivity of shot blasting is low and limited by this position. There is a certain awareness when cleaning the workpiece. It is easy to happen inside and outside the workpiece, the equipment structure is chaotic, there are many vulnerable parts, especially the blade and other parts wear fast, the maintenance time is long, the cost is high, and the one-time investment is large. On the basis of internship application, no matter which method to choose, there are many places to pay attention to.

During operation, if chemical treatment is adopted, the surface of the dividing machine can be effectively and thoroughly cleaned. However, in the process of operation, one of the problems we need to pay attention to is to have accurate time control. Please note that if the time problem cannot be controlled, it will be easier to corrode the equipment by placing the equipment in acidic or alkaline solution. Therefore, on the basis of internship application, it is best to invite those professionals to deal with it.

If mechanical disposal is adopted, there are many restrictions in actual operation. You know, the sensitivity of shot blasting is very poor in the process of accelerating the projectile by centripetal force.

In addition, in the actual operation process, there will be restrictions on the place of origin, such as the use of acidic or alkaline solution, chemical reaction with the oxide on the surface of the dividing machine workpiece, oil stain, etc.

In this case, the substance can be dissolved in acidic or alkaline solution, so the purpose of removing rust, scale and grease on the surface of the workpiece can be achieved. However, during the practice of daughter board machine, if you can't control the dose between the two, try not to use this method to deal with it, corrosion will occur.
