Detailed explanation of preparation work before SMT patch processing
In the SMT production line, the most concerned issue of smt chip processing plant owners is often how to control production costs and improve production efficiency. This involves the problem of the throwing rate of the placement machine. The high throwing rate of SMT placement machine seriously affects SMT production efficiency. Dongguan SMT processing plant will discuss with you.
SMT placement machine throwing rate refers to the placement machine in the production process, after sucking the material, it does not paste, but throws the material into the throwing box or other places, or performs one of the above without sucking the material The throwing action is called the throwing rate. Throwing material consumes a lot of material, which will prolong production time and reduce production efficiency. Therefore, every boss will solve the problem of high throwing rate as a top priority.
1. Suction nozzle problem of SMT placement machine: The deformation, blockage, and damage of the suction nozzle will cause insufficient air pressure, air leakage, and cause the material cannot be sucked, the material is incorrectly picked or the recognition is not passed and the material is thrown. What we can do is to replace the nozzle in time.
Second, SMT placement machine recognition system problems: when there is dirt or debris on the vision or laser lens that interferes with recognition, or the recognition light source is improperly selected, the intensity is not enough, and the recognition system is broken, it will cause a high rejection rate. What we have to do is to clean and wipe the surface of the recognition system frequently to keep it clean. If the intensity and grayscale are not enough, we need to adjust ourselves. If the recognition system is broken, we must consider replacing it with a new recognition system component;

3. SMT placement machine reclaiming position problem: if the reclaiming is not in the center of the material or the position due to the incorrect reclaiming height, the reclaiming is not correct, etc. will be discarded by the recognition system as invalid materials, resulting in waste. Therefore, when we work, we must adjust the reclaiming position;
4. Vacuum problem of SMT placement machine: When the air pressure is insufficient, the vacuum pipe channel is not smooth, foreign objects are blocked or the air pressure is insufficient due to vacuum leakage, etc., which will cause the material to be unavailable or fall off on the way after picking it up. Falling conditions cause waste of throwing materials. Therefore, we must adjust the air pressure to the required air pressure value of the equipment. For leakage problems, we must repair them in time. As for the blockage caused, we must clean up in time.
