[0033] As can be seen from the background art, the existing masking tape pressure maintaining tooling still needs to be improved.

[0034] Currently, masking tape pressure-maintaining tooling all uses standard customized blocks. Although they are universal for most products, as electronic products continue to develop towards precision and miniaturization, the use of existing universal parts is very inconvenient for production and has low operating efficiency.

[0035] After research, the inventor found that the recessed positioning groove on the base plate can position the workpiece to be processed. After the masking tape covers the surface of the workpiece to be processed, the downward pressure component maintains the pressure on the masking tape to ensure the tightness of the fit between the masking tape and the workpiece to be processed. At the same time, the downward pressure component rotates along the surface parallel to the vertical plate to ensure a larger stroke, which will save more effort and have a wider range of applications.

[0036] After research, the inventor also found that the vertical plate and the bottom plate are detachably connected, so that the bottom plate can be replaced according to different parts to be processed to match the positioning grooves suitable for the parts to be processed, making the product operation method more convenient and improving operation efficiency.

[0037] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.
