Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of robots, in particular to a large test table. BACKGROUND

[0002] Collaborative robots have become the focus of many enterprises due to their high accuracy and high safety. In the development process of collaborative robots, it is necessary to measure the repeatability of each joint of the robot and calibrate the torque of each joint of the robot.

[0003] In order to improve the measurement efficiency and measure the parameters of multiple groups of robot joints on the same test platform, a large test table is usually required, which causes a problem: the wires connecting the multiple test joints are very messy, which not only affects the appearance of the test table, but also affects the test process. In addition, most existing platforms only have holes on the surface for the wires to pass through, but do not solve the problem of connecting the wires to the power supply and terminals. Moreover, the power supply and terminals may be distributed in different directions around the test platform, and it is also a practical requirement to guide the wires to different directions. The present application provides a large test platform to solve the problem of wire storage when multiple objects are measured on a large platform, and to guide the wires to the required direction according to the actual terminal position, thereby solving the problem of connecting the wires to the power supply and terminals.

[0004] In the prior art, CN114527338A provides a multifunctional relay protection test platform, which specifically discloses a placement groove and a push-pull groove for placing messy objects, but the design of this structure is not aimed at the purpose of wire arrangement on a large platform, so this invention does not have the functions of arranging and guiding wires. From the functional point of view, this structure does not have the ability to solve the existing problems.

[0005] On the other hand, CN110252442B provides a multifunctional biological teaching test table, which specifically discloses an intermediate partition plate for placing messy objects, and also has a lighting and cleaning mechanism. However, as mentioned above, the design of this structure is not aimed at the purpose of wire arrangement on a large platform, so this invention does not have the functions of arranging and guiding wires.
