Based on the position signal, the controller sends a control signal to the engagement cylinder 37, so as to realize the alignment of the engagement rail 24 and the engagement rail 24. The carrying rail 28 is fixedly joined, and the controller sends a control signal to the second motor 46, so that the cart machine 27 pushes the carrying trolley 17 from the connecting section 19 upstream of the pretreatment process area 11 through the joint rail 24 to the flying frame 25 Load the track 28.

When the controller recognizes that there are at least two carriages 17 carrying the same type of workpiece among the multiple carriages 17, it controls the first motor 32 and the cart machine 27 respectively according to the workpiece information fed back by the barcode reader 54 Action, push multiple carriages 17 carrying the same kind of workpieces to the flying frame 25 one by one. Specifically, in conjunction with Figures 17-19, the controller adjusts the size and specifications of the workpiece to carry the same kind of workpieces. The number of multiple carriages 17 pushed onto the flying frame 25. For example, when the identification information shows that the workpieces currently carried by the carriage are small-sized workpieces, three carriages will be transported to the flying frame 25. Two load-bearing rails 28 are sequentially aligned with the joint rails 24, and the three carrying trolleys are respectively located in the three load-bearing tracks; when the identification information shows that the workpiece carried by the current carrying trolley is a large-size workpiece, the controller only pushes one carrier to the flying frame Trolley, the carrier trolley is located in the middle load rail 28; and when the identification information shows that the current workpiece is of medium size, the controller pushes two carrier trolleys to the flying frame, and the two carrier trolleys are respectively located in the load rails on both sides.

Finally, the controller sends a control signal to the crane driving mechanism to control the crane 22 to move directly above the flying frame 25 to lift the flying frame 25 to prepare for the pre-treatment process of the workpiece. The workpiece is lifted by the crane 22 after the pre-treatment process. Transported to the downstream of the pre-treatment process area 11, the carriage 22 transfers the current flying frame 25 to the transfer base station 14 downstream of the pre-treatment process area 11, and transfers to the pre-treatment process area 11 via the transfer base station 14 On the downstream connection section 19, it is convenient for the carrying trolley to continue to work in the next process area.
