[0046] The working process of the assembly station of this embodiment is as follows:

[0047] (1) The tray 8 with the workpiece is placed at the feeding end 21 of the connection line 2. At the same time, the top of the first blocking cylinder 25 limits the position of the tray 8. If the feeding sensor 31 detects a signal, the next step is entered, otherwise it stops and an error is reported.

[0048] (2) The first blocking cylinder 25 retracts, the stamp tray 8 is transported to the inside of the workstation body 1, and the second blocking cylinder 26 pushes out to limit the tray 8. If the in-position sensor 32 detects a signal, the next step is entered, otherwise it stops and an error is reported.

[0049] (3) The lifting cylinder 27 is pushed out, and the RFID tag on the tray 8 is read by the RFID reader 28. The RFID tag on the tray 8 is compatible with the type of the workpiece on the tray 8. In this embodiment, the workpiece is a pen holder, a seal or a car model.

[0050] (4) According to the RFID information, the articulated robot 7 connects to the corresponding gripper, moves the corresponding components on the tray 8 to the corresponding workstations on the assembly platform 4, and assembles them.

[0051] Specifically, if the workpiece is a pen holder, the articulated robot 7 connects to the first gripper 61, and then moves the pen holder to the pen holder mounting seat 411 through the clamping cylinder 613. After that, the articulated robot 7 takes the thermometer from the tray 8 through the suction cup 614, places the thermometer at the corresponding position on the pen holder, and the pressing cylinder 412 drives the pressing block 414 to press the thermometer. After the articulated robot 7 rotates the pen holder on the pen holder mounting seat 411 by 90° through the clamping cylinder 613, the articulated robot 7 takes the clock from the tray 8 through the suction cup, places the clock at the corresponding position on the pen holder, and the pressing cylinder 412 drives the pressing block 414 to press the clock. After the articulated robot 7 rotates the pen holder on the pen holder mounting seat 522 by 90° again through the clamping cylinder 613, the articulated robot 7 takes the insert from the tray 8 through the suction cup 614, places the insert at the corresponding position on the pen holder, and the pressing cylinder 412 drives the pressing block 414 to press the insert.

[0052] If the workpiece is a seal, the articulated robot 7 connects to the second gripper 62, and then moves the seal head to the seal mounting seat 421 by rotating the clamp 625, and the first electric clamp 422 clamps the seal head. After that, the articulated robot 7 grabs the seal handle from the tray 8 by rotating the clamp 625, moves the seal handle to the corresponding position of the seal head, and the linear guide 623 drives the rotating clamp 625 to move downward, and at the same time, the rotating clamp 625 rotates the seal handle and tightens the seal handle on the seal head.

[0053] If the workpiece is a car model, the articulated robot 7 connects to the second gripper 62, and then moves the model body to the car mounting seat 431 by rotating the clamp 625. After that, the articulated robot 7 grabs the wheel from the tray 8 by rotating the clamp 625, and after moving the wheel to the corresponding position of the model body, the second electric gripper 432 presses the wheel onto the model body.

[0054] (5) The articulated robot 7 moves the workpiece back to the tray 8, the second blocking cylinder 26 retracts, the stamp tray 8 is transported to the discharge end 22, and the third blocking cylinder 29 pushes out to limit the tray 8. If the discharge sensor 33 detects a signal, the next step is entered, otherwise it stops and an error is reported.

[0055] (6) The tray 8 is taken out and moved to the subsequent packaging station.

[0056] By identifying the RFID information on the pallet before assembly, this embodiment can assemble a variety of different fixed positions through one device, occupying a small area and reducing equipment costs.
