Description

Technical Field

[0001] This utility model relates to the field of industrial robot technology, specifically a cylindrical coordinate type industrial robot. Background Technology

[0002] With social development and technological progress, automated robots are gradually replacing workers in factories. In machining, the handling of workpieces mainly relies on cylindrical coordinate industrial robots, which are multi-jointed manipulators or multi-degree-of-freedom machines. They can automatically perform tasks and are machines that achieve various functions through their own power and control capabilities. They can be commanded by humans or run according to pre-programmed procedures.

[0003] The existing technology has the following shortcomings; the existing technology, in the "Cylindrical Coordinate Type Industrial Robot" with the publication number CN216372176U, "includes a base plate, a support plate, a fixed plate, a gear, a rotating shaft, two sets of connecting plates, a lifting plate, a rotating shaft, a worm gear, a drive sprocket, a worm, a first motor, a rotating device and a clamping device. The rotating device is installed on the upper part of the base plate, the support plate is fixedly installed on the rotating device, the support plate is fixedly installed on the upper part of the support plate, a rack is provided on the left end of the support plate, the fixed plate is fixedly installed on the upper part of the support plate, the gear meshes with the rack of the support plate, the gear is fixedly installed on the rotating shaft, and the rotating shaft is rotatably installed on the two sets of connecting plates";

[0004] The above-mentioned equipment is used by rotating the support plate through a rotating device, so that the support plate drives the workpiece to rotate to a suitable angle, and then the clamping device is opened to place the workpiece. The height of the lifting plate and the clamping device can be adjusted by rotating the gear, which facilitates the lifting and lowering of the workpiece and reduces limitations. However, when gripping the workpiece with the clamping device, it can only grip the workpiece at the bottom of the clamping device, which is inconvenient when gripping workpieces in different positions.
