[0002] SMD: It is the abbreviation of Surface Mounted Devices, which means: surface mount device, which is one of the SMT (Surface Mount Technology) components. In the early stages of electronic circuit board production, through-hole assembly was done entirely manually. After the first batch of automated machines were launched, they could place some simple pin components, but complex components still needed to be placed manually before reflow soldering. Surface mount components mainly include rectangular chip components, cylindrical chip components, composite chip components, and special-shaped chip components.

[0003] In the SMD processing process, it is often necessary to dock two material strips, which are generally inspected, measured, and cut one by one. This is not very efficient, and the second strip can only be processed after the first strip is disassembled on the equipment, resulting in a certain amount of displacement. The two material strips need to be realigned when docked. The above process is generally performed manually, and there are the following problems: 1. When manually docking materials, the materials in the material strips are taken out for testing. Uneven docking during manual docking will cause a high alarm rate of the placement machine; the cost of manually training a material receiver is high; manual measurement has a lag, and the existing equipment cannot simultaneously detect the integrity of new and old materials, and the old material model cannot be effectively detected during the docking process.
