The plurality of suction heads are moved toward the first transmission module 21 by the Z-axis drive assembly 315, the first and second suction heads take materials from the first material tray, and the third and fourth suction heads take materials from the second material tray.

[0070] In step four, after the materials are sucked, the cross beam 311 is moved above the vision module to take a picture by using the upward camera to detect the state of the material, then the cross beam 311 is moved above the second transmission module 22 by the Y-axis main drive device 313, the plurality of suction heads are moved toward the first transmission module 21 by the Z-axis drive assembly 315, the material is moved above the corresponding material, and then is pressed to be attached. In this process, each suction head can be independently moved along the Y-axis direction by the auxiliary Y-axis drive device 314 to adjust the attachment position.

[0071] In step five, the used material tray is moved toward the pre-storage module 23 at the discharging end along with the transmission component 235, the workpiece is moved above the supporting plate 2381, the workpiece is lifted by the supporting plate 2381 while the stop plate 233 moves out of the bottom of the pre-storage space, until the workpiece is lifted into the pre-storage space by the supporting plate 2381, at this time the stop plate 233 moves below the pre-storage space from both sides, and the supporting plate 2381 descends to realize the discharging and storage of the material tray. The material carrier flows along the second transmission module 22 to the next process.

[0072] In other embodiments, the four working modules 32 can all be dispensing mechanisms, or some are dispensing mechanisms and some are attachment mechanisms.
