1. Identify system problems

In the process of material identification of Samsung SMT card, if there is a system problem and the lens is not clear, impurities will interfere with machine identification. When the identification light source is not selected properly, the system will be seriously damaged. The surface of the identification system should be cleaned regularly, the lens should be kept clean, and the intensity and gray level of the light source should be adjusted appropriately. When the identification system components are damaged, they should be replaced in time.

2. Vacuum problem

When the pressure of Samsung SMT card is insufficient, the vacuum trachea channel is not smooth, and foreign objects enter and block the vacuum channel. If there is an appeal, the material will fall off during the pasting process because it is picked up. The pressure gradient should be adjusted to a reasonable value, and the pneumatic pipeline should be cleaned to repair the gas path.
