The main reason of the SMT machine chip throwing

The so-called throwing material, refers to the feeding machine in the suction after the non-stick material, but the material into the throwing box or other places, or do not suction the above throwing action.

The main reason for throwing material

Reason 1: The suction nozzle is defective, deformed, blocked and damaged, resulting in insufficient air pressure and air leakage, which leads to the inability to absorb materials, incorrect material taking, and the materials are thrown out due to the failure to pass the identification.

Reason 2: Problems with the recognition system, poor eyesight, unclean vision or laser lens, sundry interference in recognition, improper selection of recognition light source, insufficient intensity and gray level, may lead to the failure of the recognition system.

Reason 3: Location problem, the recovered material is not in the material center, the recovery height is not correct, resulting in deviation, the recovered material is not correct, there is deviation, the identification of the corresponding data parameters do not match, the identification system as invalid material discarded.

Reason 4: vacuum problem, air pressure is insufficient, the vacuum duct passage is not smooth, the guide is blocked the vacuum passage, or the vacuum leakage, resulting in insufficient air pressure, and the material cannot be taken or dropped on the paste road after taking the material.

Reason 5: There is a problem in the program. The parameters of each component in the edited program are not correctly set, and the actual size and brightness of incoming materials are not matched, which leads to identification failure and discard.
