Description

technical field [0001] The invention relates to the technical field of chip mounters, and more specifically relates to the nozzle feeder arrangement of a multi-head chip mounter and an optimization algorithm for component mounting sequences. Background technique [0002] The workflow of the multi-head placement machine is that the multi-head goes to the feeder station to pick up multiple chip components, and after visual calibration, it moves to the placement position and places them one by one. The PCB component list includes the mounting coordinates of different components, the nozzle model, the feeding type and the feeder model. When retrieving, in order to maximize the efficiency, the multi-head placement machine needs to try to make the entire retrieving process as many as possible and minimize the displacement; when placing, in order to maximize the placement efficiency, the placement During each round of placement of the head, try to minimize the placement displaceme...

AI Technical Summary

Problems solved by technology

[0005] First, the operator manually specifies the nozzle and feeder arrangement plan, which cannot achieve the same pick-up and minimum displacement as possible, so the efficiency of pick-up is greatly reduced

[0006] Second, the operator manually arranges the placement sequence, which cannot minimize the displacement of the placement head during placement, so that the optimal placement sequence cannot be obtained, which reduces the placement efficiency

[0007] Third, the operator manually programs the pick-up and placement data one by one, which takes a long time and is time-consuming, error-prone, and difficult to find, resulting in a high pick-and-place error rate and low programming efficiency
