and step 3: when the pipe is conveyed to the station of the detection guide mechanism 34, the visual detection mechanism 51 detects the defects of the pipe, if the pipe has larger defects, the pipe is transmitted to an upper computer, the upper computer sends the defects to a PLC (programmable logic controller), the PLC controls the defects to alarm, and the pipe is manually removed;

and 4, step 4: the upper computer sends out an order number, and the PLC analyzes the data parameters to obtain the length data of the pipe and transmits the length data to the console 21;

and 5: after the data are obtained, the control console 21 controls the positioning cylinder 23 to enable the positioning cylinder 23 to drive the baffle assembly 8 to automatically move to the cutting length distance;

step 6: the conveying mechanism 33 continues conveying, when the pipe is conveyed to the cutting station, the sensor 22 detects the incoming material until the pipe is conveyed to the designated position of the cutting station, and at the moment, the conveying motor 47 stops rotating;

and 7: when the pipe is conveyed to the position of the baffle assembly 8, the sensor 22 detects that the pipe is in place, the first clamping mechanism 5, the second clamping mechanism 6 and the adjustable clamping mechanism 7 automatically press the pipe, wherein the adjustable clamping mechanism 7 adjusts the clamping position according to the length of the tail end of the pipe;

and 8: the saw blade 11 in the cutting mechanism 4 automatically extends out for cutting, and after the cutting is finished, the first clamping mechanism 5 and the second clamping mechanism 6 loosen the pipe material to flow to the transplanting unit 26;

and step 9: the transplanting unit 26 station continuously moves the cut pipe towards the pipe advancing direction, and when the pipe is conveyed to the processing unit 27, the robot 66 grabs the pipe in an electromagnet mode;

step 10: the material conveying unit 24 and the cutting unit 25 continue the steps 1-8, the steps are sequentially circulated until the 6-meter pipe is cut in a segmented mode, the residual waste materials enter a recovery mechanism (not shown in the figure), the next pipe can be conveyed, and the steps are repeatedly circulated;

step 11: the robot 66 is conveyed into the processing machine tool 65 through the track points, the robot 66 exits from the processing machine tool 65, and meanwhile, the processing machine tool 65 starts to process; then the robot moves to the unit 26 to grab the pipe subjected to subsequent cutting, and the pipe is conveyed to another processing machine tool 65 through the track points; the processing machine tool 65 and the robot 66 are in signal interaction fit, after the pipes in the processing machine tool 65 are processed, the robot 66 takes out the processed pipes and sends the processed pipes to the transplanting unit 26 for code spraying, and the robot 66 sequentially performs circular processing, picking and placing;

step 12: when the sensor 64 detects that the pipe is in place, the stop cylinder 55 works to prevent the processed pipe from moving continuously;

step 13: the code spraying mechanism 54 automatically produces digital codes according to the contents of the tube codes and the like, and the code spraying mechanism 54 starts to spray codes;

step 14: after the code spraying is finished, the stop cylinder 55 is relieved, and the pipe subjected to the code spraying is discharged to a discharging trolley 57 through a discharging unit 29; when the weight of the pipe material in the blanking trolley 57 reaches a certain weight (set weight), a buzzer alarms (not shown in the figure) to prompt that the blanking trolley 57 needs to be replaced manually.

While particular embodiments of the present invention have been described in the foregoing specification, various modifications and alterations to the previously described embodiments will become apparent to those skilled in the art from this description without departing from the spirit and scope of the invention.
