Description

Technical Field

[0001] The utility model relates to the technical field of robot workstations, in particular to a positioning device for a robot workstation. Background Art

[0002] A robot workstation refers to one or more robots, equipped with corresponding peripheral equipment, such as positioners, conveyors, fixtures, etc. When the robot workstation processes the workpiece, a positioning device is generally required to fix the workpiece and then cooperate with the robot workstation to perform processing operations on the workpiece.

[0003] Traditional positioning devices generally position the workpiece through a clamp. The angle of the workpiece after positioning cannot be adjusted. After processing one side of the workpiece, the staff needs to cooperate in the face-changing operation, which reduces the working efficiency of the positioning device and increases the work intensity of the staff. At the same time, the clamp is generally bolted to the fixed frame through multiple sets of fasteners. When the clamp is damaged, the workstation personnel need to spend a lot of time to disassemble and assemble it, which brings inconvenience to the maintenance of the positioning device.

[0004] According to the publication number: CN219768027U, a positioning auxiliary device for metal workpiece processing is provided, which includes a bottom plate, a cross groove is provided on the top of the bottom plate, a fixed plate is fixedly connected to the inner bottom wall of the bottom plate, a motor is fixedly connected to one side of the fixed plate, the output shaft of the motor is fixedly connected to a bidirectional screw through a coupling, a movable block is movably connected to the outer wall of the bidirectional screw, a positioning block is fixedly connected to the inner wall of the bottom plate, a lead screw is movably connected to one side of the positioning block, a turntable is fixedly connected to one end of the lead screw, and a threaded block is movably connected to the outer wall of the lead screw. The positioning auxiliary device for metal workpiece processing can improve the firmness of positioning when positioning the metal workpiece, and can fully clamp it to avoid the metal workpiece from sliding and dislocation during processing, which not only improves the processing quality, but also improves the stability of clamping, and is convenient for the processing and use of metal workpieces.

[0005] According to the positioning auxiliary device introduced above, the angle after positioning cannot be adjusted. After processing one side of the workpiece, the staff needs to cooperate in the face-changing operation, which leads to a decrease in the working efficiency of the positioning device and an increase in the work intensity of the staff. At the same time, the fixture is generally bolted to the fixed frame through multiple sets of fasteners. When the fixture is damaged, the workstation personnel need to spend a lot of time on disassembly and assembly, which brings inconvenience to the maintenance work of the positioning device. Therefore, we need to propose a positioning device for a robot workstation. Utility Model Content
