Laser window opener

Abstract

The invention discloses a laser window opener which comprises a rack, an XY-axis driving mechanism, a working platform, a Z-axis driving mechanism, a laser and a CCD detector. The rack comprises a rack platform and a rack door frame. A cross beam of the rack door frame is suspended above the rack platform, the XY-axis driving mechanism is mounted on the rack platform, the working platform is mounted on the XY-axis driving mechanism and is located below the cross beam, the XY-axis driving mechanism drives the working platform to slide below the cross beam along the length and width directions of the rack, the working platform comprises a clamping mechanism, the Z-axis driving mechanism is mounted on the rack door frame, the laser is mounted on the Z-axis driving mechanism and is located above the working platform, the laser head of the laser faces the working platform downward, the Z-axis driving mechanism drives the laser to ascend or descend, and the CCD detector is mounted on the laser or the Z-axis driving mechanism. Therefore, the laser window opener has the advantages of being high in work efficiency and high in processing precision, reducing artificial influence factor and being suitable for windowing various complicated patterns.

Description

technical field [0001] The invention relates to the field of mechanical equipment, in particular to a laser window opening machine suitable for opening windows on PCB boards. Background technique [0002] With the development of science and technology and the progress of humanities, the application technology of laser is becoming more and more developed, and the equipment of laser is becoming more and more advanced, and the laser window opener is a kind of laser equipment. [0003] For flat-plate workpieces such as plastic flat panels and printed circuit boards, in the process of partial electroplating, it is necessary to apply glue to the entire board first, and then cut off the glue on the parts that need to be electroplated by "window opening"; traditional window opening The method is to cut the colloid manually with a knife and a ruler. Its disadvantage is that there are relatively large human factors. If the force of the knife is too small, the colloid cannot be effect...

AI Technical Summary

Problems solved by technology

The disadvantage is that the human influence factor is relatively large. If the force of the knife is too small, the colloid cannot be effectively cut; if the force of the knife is too large, it will damage the surface of the colloid.

Secondly, the accuracy is insufficient. Manual tapping can generally only distinguish the accuracy of 1 mm. If the accuracy requirement is higher than this value, it will be difficult to complete the tapping operation.

In addition, there is also the problem of low work efficiency. Using a knife and ruler manually is inconvenient to operate and the efficiency of tapping rubber is low. Especially when encountering complex graphics, the efficiency is even lower.

Finally, personal pollution is serious, and long-term contact with colloids will cause certain harm to the skin
