[0037] During application, the staff places the iron pieces on the four groups of loading stations 302 on the turntable 301, and eight iron pieces can be placed in each group of loading stations 302. During loading, the driving motor 303 drives the turntable 301 to rotate, so that one group of loading stations 302 rotates to the position corresponding to the jacking mechanism 304. At this time, the jacking mechanism 304 jacks up the height of a workpiece through the jacking opening of the turntable 301, and then the manipulator in the manipulator conveyor 2 absorbs and transfers the eight iron pieces placed in the loading station 302 by negative pressure suction, so as to place them on the heating plate 501 in the precision positioning station 5 for further processing. The heating treatment is performed, and when the iron piece is heated, the manipulator in the manipulator conveyor 2 sucks the transferred workpiece again by negative pressure suction, transfers it to the mold of the injection molding machine 1, and performs injection molding. After the injection molding is completed, the finished workpiece is taken out, and the manipulator in the manipulator conveyor 2 transfers it and places it on the conveyor belt 4 by negative pressure suction; when the iron pieces of one group of loading stations 302 are taken out, the lifting mechanism 304 descends, and the driving motor 303 drives the turntable 301 to rotate again, so that another group of loading stations 302 is rotated to the position corresponding to the lifting mechanism 304, so as to realize automatic loading and unloading operations;

[0038] The utility model is also provided with an area restriction base 6 to limit the activity area of ​​the staff, so that when performing the above-mentioned automated operation, the staff is required to stand on the stepping plate 604 of the area restriction base 6 all the time, and the area restriction base 6 can be fixedly connected to the ground through fasteners inserted through the fixed installation holes 602, so that it can be fixedly installed in front of and below the manipulator conveyor 2, so that the staff standing on the stepping plate 604 of the area restriction base 6 can clearly observe the operating status of the current equipment; and when the staff stands on the stepping plate 604, Under the weight of the staff, the pressing plate 604 moves down along the pressing groove 605 until the bottom end surface of the pressing plate 604 contacts the bottom end surface of the inner end of the pressing groove 605. At this time, the spring support 607 is in a compressed state, and the pressing plate 609 that was originally in contact with the timing on-off switch 6011 will also move down along the pressing cavity 6010, and it will be separated from the button end of the timing on-off switch 6011. When the staff leaves the activity range of the area restriction base 6, there is no more weight of the staff pressing down, and the spring support 607 in a compressed state quickly The reset rebound pushes the pressing plate 604 to move upward along the pressing groove 605, and the synchronous pressing plate 609 will also move upward along the pressing cavity 6010, thereby pressing the timing on-off switch 6011 again.

When the time when the staff leaves the area restriction base 6 exceeds the set timing value of the timing module 6013, it can be determined that the staff is away from work beyond the time limit. The timing module 6013 feedbacks a signal to the microcontroller 6014, and the microcontroller 6014 controls the buzzer 603 to start, so as to realize a high-decibel buzzer reminder, which can not only remind the staff who are away from work, but also remind the responsible management personnel, so that they can know that the current staff has been away from work beyond the time limit, which can serve as a basis for subsequent processing of the overtime leave.
