Beneficial effects

[0016] Through the setting of the adjustment mechanism, the present invention realizes the adjustment of the position of the adjustment air pipe. When it is necessary to move the adjustment air pipe, only need to pull out the limit member outward. At this time, the limit insertion rod will disengage from the limit hole in the positioning slider, releasing the lock on the adjustment air pipe. Subsequently, the adjustment air pipe can be manually adjusted by pushing the fixed ring. During the adjustment process, the positioning slider continuously jumps under the action of the positioning compression spring and is inserted into the positioning slot, thereby realizing the stagewise precise positioning of the adjustment air pipe. After the position adjustment is completed, only need to insert the limit insertion rod back into the positioning slider to fix the current position of the adjustment air pipe, making it adapt to the assembly requirements of steel sheets of different specifications, significantly improving the applicability and flexibility of the equipment.

[0017] In addition, through the setting of the automatic replacement mechanism, the automatic replacement of the loading suction cup is realized. When the loading suction cup is damaged, the air pressure inside the adjustment air pipe changes, the pressure sensor is triggered and transmits a signal to the PC controller. After receiving the signal, the controller will control the adjustment servo motor and the driving servo motor to drive the adjustment air pipe to move directly above the recycling box. Subsequently, the micro electric push rod is activated to push the installation limit block out of the installation limit slot, so that the loading suction cup falls into the recycling box under the action of gravity. Next, the PC controller continues to control the adjustment air pipe to move above the magazine table and communicates with the UHF tag through the micro reader to read the UID information therein. The photoelectric sensor is used to detect whether there is a usable loading suction cup in the suction cup slot corresponding to the UID and feedback the detection result to the PC controller, which saves the data to the database. When the micro reader successfully reads the UID of the UHF tag, the controller will compare the UID with the records in the database. If it is confirmed that there is a usable loading suction cup in the corresponding suction cup slot, the controller will activate the adjustment electric push rod to drive the adjustment air pipe to move downward, so that the installation pipe of the loading suction cup in the suction cup slot is inserted into the lower end inside the adjustment air pipe. At the same time, the installation limit block is inserted into the installation limit slot under the action of the installation compression spring, thereby completing the automatic replacement and fixation of the loading suction cup, realizing the full automation of the entire suction cup replacement process without manual intervention, effectively reducing the labor cost and the labor intensity of the operator, significantly improving the work efficiency and operation continuity, and meeting the actual requirements of the high-efficiency and stable operation of the production line.

[0018] In addition, through the above arrangement of the mechanism, not only is the flexible adjustment of the position of the adjusting air pipe realized to meet the assembly requirements of steel sheets of various specifications, but also the automatic identification, disassembly and replacement of the suction cups are realized, further improving the intelligent level and production adaptability of the equipment.
