Pasting method for multilayer circular product, and multilayer circular product

The invention discloses a pasting method for a multilayer circular product. Because a feature mark is not shielded by an avoiding position of a second pasting part, the feature mark of a first pastingpart still can be taken as the reference for grabbing during the pasting of other second pasting parts, and the steps 3-6 are continuously performed during the pasting of other second pasting parts till all second pasting parts are pasted. Moreover, because each second pasting part takes the feature mark of the first pasting part as the reference for grabbing, the errors are independent during the pasting of each layer, and cannot be accumulated, thereby improving the pasting precision, reducing the defective products, and reducing the production cost. 本发明公开了种多层圆形产品的贴合方法，由于特征标记不被第二贴合件的避空位所遮挡，所以在贴合其他第二贴合件时，仍能以第贴合件的特征标记作为基准进行抓取，而贴合其他第二贴合件时则继续重复执行步骤3至步骤6，直到所有的第二贴合件完全贴合完毕为止，而由于每层第二贴合件都是以第贴合件的特征标记作为基准进行抓取，所以每层贴合时的误差互不干扰，不会累积，由此提高贴合精度，从而减少了不良品，降低生产成本。
