Description

Technical Field

[0001] This utility model relates to the field of industrial robot technology, specifically to an industrial robot coordinate system calibration module. Background Technology

[0002] The earliest known industrial robot, conforming to the ISO definition, was completed by Griffith P. Taylor in 1937 and published in the Meccano magazine in March 1938. It was almost entirely constructed from crane-like components and powered by a single electric motor. Five axes of motion were possible, including rotational movement. Automation was achieved using perforated paper tape energized solenoids, which facilitated the movement of the crane's control levers. The robot could stack blocks on a pre-set pattern. The required number of revolutions for each motor needed to move was first plotted on graph paper. This information was then transferred to the paper tape, thus also driving the robot's individual motors. An industrial robot is a multi-jointed manipulator or multi-degree-of-freedom machine device for industrial applications. It can automatically perform tasks and is a machine that achieves various functions through its own power and control capabilities. It can be commanded by humans or operate according to pre-programmed procedures. Modern industrial robots can also act according to principles established by artificial intelligence technology. A complete replica of the robot built by Christschütt in 1997 was also documented. In the use of industrial robots, the tool coordinate system and workpiece coordinate system need to be calibrated before each teaching operation to ensure the accuracy of the industrial robot.

[0003] The existing technology has the following shortcomings: The existing technology, disclosed in CN202020203184.2, discloses an industrial robot coordinate system calibration module, including a calibration disk. An X-axis plate is fixedly connected to the top of the calibration disk, a Y-axis plate is fixedly connected to the top of the calibration disk, a Z-axis column is fixedly connected to the top of the calibration disk, a suction cup is fixedly connected to the top of the suction cup, a calibration column is fixedly connected to the top of the calibration disk, and a vertical column is fixedly connected to the top of the calibration disk. A sliding groove is provided on one side of the vertical column, and one side of the vertical column is movably connected to… The device includes a slider, an infrared emitter fixedly connected to one side of the slider, a first knob threadedly connected to one side of the slider, a support column fixedly connected to the bottom of the calibration plate, a holding plate fixedly connected to the bottom of the support column, a locking hole fixedly connected to the top of the holding plate, a scale movably connected inside the locking hole, a circular groove formed on the top of the holding plate, a locking slot formed on the top of the holding plate, a locking ring provided on the top of the locking slot, a second knob threadedly connected to one side of the locking ring, and a guide body fixedly connected to the top of the locking ring.

[0004] The aforementioned equipment has a basic integrated design, which makes it inconvenient to disassemble, thus making it relatively troublesome to carry and store. In addition, the calibration column is fixed with a suction cup, which is prone to falling off and being damaged by external forces, affecting the working effect. While existing equipment can also be fixed with bolts, which provides higher stability, the installation and disassembly are more troublesome, thus limiting its working use. Utility Model Content
