Detailed Description of Embodiments

[0011] Referring to the attached Figure 1-5 drawings, the present utility model provides a three-station robot welding workstation, which comprises a welding robot 1 and further comprises a BASE plate 2. Three groups of welding fixtures arranged in a "triangular" layout are arranged on the BASE plate 2. An arc light protection plate 7 is arranged between the welding robot 1 and each group of welding fixtures. The workstation further comprises an integral protective cover 9, and protective doors 10 corresponding to the three groups of welding fixtures are arranged on the integral protective cover 9; a baffle 13 is further arranged between every two adjacent groups of welding fixtures.

[0012] Preferably: the baffle cooperates with the arc light protection plate, so that the three groups of welding fixtures form relatively independent working areas, effectively preventing the welding station from affecting operators at the station where workpieces are being replaced.

[0013] Preferably, the arc flash protection plate 7 is fixed on the protection plate mounting bracket 8, and the protection plate mounting bracket 8 is raised and lowered in conjunction with the BASE plate 2 via a lifting cylinder 6. Specifically, two sets of synchronously lifting cylinders have their upper free ends connected to the protection plate mounting bracket via a connecting frame, and their lower ends are fixed to the BASE plate via bolts. By controlling the two lifting cylinders to raise and lower the arc flash protection plate, the protection of personnel during welding operations is achieved. To ensure the reliability of the raising and lowering, guides or limit devices can also be installed.

[0014] Preferably, the base plates of the three sets of welding fixtures are fixed to the BASE plate 2 by bolts.

[0015] Preferred: The three sets of welding fixtures are welding fixture I3; welding fixture II4; and welding fixture III5.

[0016] Preferably, it also includes a feeding device 11 and a control device 12; the feeding device is used to provide consumables to the welding robot, and the control device is used to control the operation of the robot and related components. The structure and connection relationship of the two are existing technologies and will not be described in detail.

[0017] Preferably, the BASE plate includes channel steel, steel plate, reinforcing ribs, and anchor expansion bolts; the channel steel, reinforcing ribs, and steel plate are fixed together by welding, and the entire BASE plate is installed in a predetermined area by anchor expansion bolts; forming an installation plate for installing welding fixtures (or welding robots, etc.) at three workstations.

[0018] Preferably, the overall protective cover is assembled from profiles and steel plates by welding or bolting, forming a protective shield for the entire working area to prevent welding spatter and arc light from harming surrounding workers. The protective door is a roller shutter structure, and its opening and closing are controlled by a motor.

[0019] The working process of this utility model structure is as follows: When the welding operator places the workpiece onto the fixture, the fixture is clamped by the air valve. After the workpiece is installed and clamped in place, the welding arc protection plate is lowered by the lifting cylinder under the control of the PLC. After the motor drives the protective door to the lowering position, the robot begins the welding operation. The operator can then go to the other two workstations to install other workpieces. After the robot finishes its welding operation, it returns to its original position. The PLC controls the cylinder to raise the arc protection plate, and the motor drives the protective door to the uppering position. After the clamping position is raised, the operator can remove the workpiece. At the same time, the robot performs welding operations at the other two workstations. After the workpiece at a workstation is installed, the protective door is lowered to await the robot's welding operation. In this way, welding can be performed at one workstation while the other two workstations are clamped, effectively improving the efficiency of the welding operation. The use of robots for welding operations can also greatly improve the welding quality. When a product is upgraded or an old product is phased out, all that is needed is to disassemble the old fixture, redesign and replace it with a new product's welding fixture according to the original base plate's structural dimensions, teach and program the robot to complete the new program, and the upgrade and switchover can be completed. In this way, if the old product is produced again in the future, the old fixture can be switched back to continue production.
