Pcb assembly PCB component adjustment method

First of all, the mechanical adjustment of PCB assembly PCB components, nozzle rotation adjustment direction, this method can achieve limited accuracy, it’s not suitable for future models.

Therefore, the camera recognition, the X-Y coordinate system adjusts the position, the nozzle rotates itself to adjust the direction, the camera is fixed, and the placement head plane is swept over the camera for image recognition.

Under normal circumstances, there are dozens to twenty placement heads installed on the turret. Each placement head is equipped with 2 to 4 vacuum nozzles (earlier models) or 5 to 6 vacuum nozzles (current models). ). Due to the characteristics of the turret, the action is subtle, the nozzle is changed, the feeder is moved in place, components are taken, component identification, angle adjustment, workbench movement (including position adjustment), placement of components actions can be completed in the same time period, so the real high-speed PCB assembly and smt process can be realized. At present, the fastest time period reaches 0.08~0.10S/piece.

This model is superior in speed and suitable for assembly and processing of large quantities of PCB. However, it can only use ribbon packaging components. If it is a dense pin or a large integrated circuit, only pallet packaging cannot be completed.Thus it depends on mutual cooperation of other machine modes.
