Center Alignment System for Thick Film Screen Printer

Center Alignment System for Thick Film Screen Printer Description:

• Pressure sensor diameter 18mm* thickness 6.35mm

• 48 joint potentiometer 48mm*80mm*0.8mm

• GPS media antenna 25*25*4mm or smaller

It can eliminate the printing positioning deviation caused by the component contour error, so as to ensure the repeated positioning accuracy of multiple repeated thick film printing pattern overprinting.

For structural ceramics or other functional ceramics fired by casting stamping or powder pressing, often due to the uncertainty of material, pressing or firing, the shape of the component fired is inconsistent due to shrinkage, and there is a certain size deviation, which makes the subsequent printing and other processing technology positioning problems, such as the application of a right Angle for the side positioning of square porcelain pieces. Then all the external errors of the chip will accumulate in the direction of another right Angle, and if the right Angle is not the standard 90 degrees, then the standard edge of the placement of the chip can not be determined, so that the placement position of the chip itself can not be consistent, so that the precision of the printing position can not be mentioned. Similarly, for circular components, if the outer circle tolerance is very large, if the center of the circle cannot be found, it will also cause the position to be uncertain.

This fixture adopts the principle of center positioning, in the limited space through fine design and processing, set 3 groups of independent movement of automatic parallel clamping mechanism, the application of the component's own center point positioning, eliminating the positioning deviation caused by the shape of the component, so as to achieve the purpose of high-precision printing positioning.

The fixture changes different clamping heads and can hold components of different sizes or shapes.

3 sets of independent automatic parallel clamping mechanism, clamping head 3mm German 94 degree tungsten steel rod, after wear can be rotated direction, the built-in cylinder to push the clamping head, spring contraction automatic center positioning, clamping force of 5N per group. The repeated positioning accuracy is less than 0.015mm, and the service life is 10 million times

When the same batch of ceramic chips, the same press and screen are available in technical support, PPK data is compared between traditional positioning and central positioning printing results.
