Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of printed circuit board processing, in particular to a conveying device for copper-clad foil substrate. BACKGROUND

[0002] It is known that the copper-clad foil substrate is the core substrate for manufacturing printed circuit boards. In the process of production, it is necessary to convey the copper-clad foil substrate for the purpose of transfer between processes and packaging. The mainstream conveying method in the prior art is completed by a belt conveyor. In recent years, cleaning, guiding and protection functions have been added to reduce the possibility of copper-clad foil substrate adhering to impurities. In some environments with high cleanliness requirements, a roller conveyor is also used for conveying.

[0003] In the automatic processing of existing copper-clad foil substrates, the copper-clad foil substrates are usually conveyed to a positioning location, then picked up by a mechanical arm or a machine table, and then moved to a processing location. Although this method can continuously and stably work, it is time-consuming to pick up and move the substrate. In addition, the substrate needs to be repositioned for single processing, and the efficiency needs to be improved. Moreover, the conveying device in the prior art, whether it is a belt type or a roller type, is large in size and has single functionality. Based on the above-mentioned situation, we found that the copper-clad foil substrate conveying device in the prior art is difficult to avoid the above problems at the same time. Therefore, we propose a conveying device for copper-clad foil substrate that can customize the guide rail for the conveying direction and can use the conveying device for copper-clad foil substrate as a processing table to replace the worktable of some equipment for direct processing, thereby saving the moving and grabbing steps, improving the efficiency, not needing to reposition the substrate every time, effectively improving the functionality of the conveying device, and adjusting the state of the copper-clad foil substrate as needed to adapt to the processing equipment. SUMMARY
