[0002] In the processing of aluminum tubes, the existing process is to manually collect the tubes cut by the tube cutting machine into the material frame, manually transport them to the required workstations, manually place the workpieces on the machine tool, and be responsible for the insertion and removal of the cores during the processing. The above contents have a low degree of automation, and the processing loading and unloading and transportation are heavily dependent on manual labor, resulting in insufficient production capacity;

[0003] There are four technical issues that need to be solved:

[0004] 1. The progress of workpieces between multiple processing workstations is different, making it difficult to allocate and schedule workpieces;

[0005] Second, the machine tool has high requirements for feeding accuracy, and the robot cannot directly grab and place it;

[0006] 3. The pipe is thin, and polyurethane needs to be stuffed in the middle before and after processing to avoid deformation during processing;

[0007] Fourth, the AGV itself has poor precision, and it is difficult to accurately transport tooling pallets at fixed points. Summary of the invention

[0008] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a fully automatic processing and transfer production process for aluminum tubes, the components used in the fully automatic processing and transfer production process for aluminum tubes include a material sorting table, a robot workstation, a processing machine tool, an automatic feeding tool, a tool limit mechanism and a tool plate, wherein the following production steps are included:

[0063] Working principle: After the pipe is cut by the cutting machine, it is pushed into the conveyor line by the cylinder and then sent to the loading stations of each workstation in turn. Each workstation will adaptively alarm the master control platform according to the number of workpieces to be processed and cached. The master control platform is responsible for the workpiece conveying position. After the workpiece arrives at the required station, it is blocked by the blocking cylinder. The sensor detects the status of the workpiece. The cylinder at the upper end of the line pushes it into the material sorting table and opens the baffle of the material sorting table, which solves the problem of difficulty in allocation and scheduling.

[0064] The material sorting table is mainly used to guide and position the rolling of pipes. The frame is welded from profiles. The centering cylinder is responsible for the centering of the workpiece, and the push cylinder is responsible for pushing the workpiece to the loading position and is detected by the material sensor. The full material sensor detects whether the workpiece is full and transmits the material status to the master control platform. The master control platform reasonably allocates the workpiece and cooperates with the robot workstation to grab it. Taking into account the high requirements of machine tool processing accuracy and the increased placement deviation of the robot, it is necessary to use automatic loading tooling to achieve precise loading. The robot is responsible for placing the workpiece grabbed from the material sorting table on the loading tooling, and the push cylinder pushes the workpiece to the machine tool processing station and is guided by the slider guide. This process solves the high requirements of machine tool loading accuracy.

[0065] To meet the process requirements, the robot cooperates with the mandrel threading and pulling tool to insert the shaft core into the pipe before loading. After the machine tool processing is completed, the robot removes the processed workpiece and cooperates with the mandrel threading and pulling tool to push out the shaft core. This solves the need for mandrel threading and pulling during the processing.

[0066] The robot places the workpiece on the tooling plate and adds a tooling limit mechanism to ensure the positioning accuracy of the tooling plate, which is more conducive to the subsequent AGV trolley's handling operations. The accuracy problem of the AGV trolley is solved here.

[0067] Finally, the AGV transports the full stack of tooling boards to other areas.

[0068] In summary, the present invention replaces the original manual transfer and loading and unloading operation process, which not only ensures the safety of personnel, but also greatly speeds up the production rhythm, improves production capacity, and improves the degree of automation.
