The placement rate of JUKI placement machine refers to the number of components placed within 1h, and the unit is c/h. The placement rate is the placement speed measured by the JUKI placement machine manufacturer under ideal conditions. The calculation of the theoretical speed does not consider the PCB loading and unloading time, the patch distance is the closest, and only a small number of components (about 150 chip components) are attached, and then the time it takes to mount one component is calculated, and the number of 1h placement is calculated based on this. .

The meaning of the placement rate The so-called placement rate refers to the ratio of the actual number of devices mounted to the number of suctions within a certain period of time, namely: the placement rate = X99.99% of the number of suctions. The total number of discarded pieces refers to the number of suction errors and identification errors. The number of pieces, the number of vertical pieces, the number of lost pieces, etc., and the identification error is divided into two types of device specification size error and device optical identification poor.

The whole process of JUKI placement machine placement is purely from the perspective of equipment. When the height of the suction nozzle and the relative position of the center of the suction nozzle and the feeder are correctly set, the main factors affecting the placement rate of the equipment are: At the pickup location, according to the production information intelligence of equipment statistics, its influence accounts for more than 80% of the entire influencing factors. The reason for this is, on the one hand, the feeder on the device storage and transportation device, and on the other hand, the suction nozzle. About 60% and 40% of the videos of the feeder between the two are caused by the pollution of the suction nozzle.
