[0004] Although the above-mentioned ion beam processing device can flexibly move the ion source, the clamp for clamping the workpiece cannot be adaptively adjusted, the thickness and size of each workpiece may not be consistent, if the clamp cannot be adaptively adjusted to the workpiece, the problem of shaking of small workpieces and installation of large workpieces may occur, thereby affecting the processing effect of the workpiece. And in the ion beam processing process, any slight shaking or deviation may cause the processing precision to decrease, thereby affecting the production quality of the workpiece, therefore, the clamp needs to stably fix the workpiece so that it remains stable during the processing process, thereby ensuring the precision of the ion beam processing. In addition, some workpieces need to be regionally divided during the ion beam processing process, so as to compare and analyze the characteristics and states of the workpiece before and after processing; however, the existing clamp can only clamp the whole workpiece for processing, and cannot process the workpiece in different regions or cannot accurately position the position of the region, thereby affecting the processing of the workpiece, so that the comparison data before and after processing of the workpiece cannot be accurately obtained, the clamp can also use a baffle to partially shield and divide the region, but the baffle needs to be manually adjusted, so that the position of the baffle is not accurate enough, thereby affecting the processing effect of the workpiece, and the processed workpiece may have precision errors.
