Industrial robots are multi-joint manipulators or multi-degree-of-freedom machine devices widely used in the industrial field. They have a certain degree of automation and can achieve various industrial processing and manufacturing functions by relying on their own power and control capabilities. Industrial robots are widely used in various industrial fields such as electronics, logistics, and chemicals.

Among them, when testing the antenna, the antenna is clamped by an industrial robot to perform near-field testing and far-field testing. The degree of automation is extremely high. The user only needs to complete the installation of the antenna to be tested and the calibration of the far-field beacon. The system can test various antenna indicators without intervention. The position of the antenna to be tested is controlled by the robot, and the position of the near-field beacon can also be adjusted, which effectively ensures the test accuracy and greatly improves the antenna test efficiency.

There are also ejectors 5 between the support plate 4 and the bottom plate 3. There are several ejectors 5 distributed along the circumference of the bottom plate 3. The ejectors 5 can eject the support plate 4 vertically, so that the support plate 4 is tilted after installation. Therefore, by controlling the tilt angle of the support plate 4, the horizontal accuracy of the support plate 4 can be adjusted in a timely and convenient manner, avoiding errors caused by the tilt of the base body 1 when the robot 2 is working.

In detail, a fastener 6 is provided between the support plate 4 and the bottom plate 3, and the support plate 4 and the bottom plate 3 can be fixedly connected by the fastener 6. In more detail, a plurality of first through holes 7 are provided in the circumferential direction on the support plate 4, and a plurality of second through holes 8 are provided in the circumferential direction on the bottom plate 3, and the first through holes 7 and the second through holes 8 are located opposite to each other, and the fastener 6 includes a screw rod 9 penetrating the first through holes 7 and the second through holes 8, and the support plate 4 and the bottom plate 3 are connected and fixed by the screw rod 9, and a nut and a gasket are also provided at one end of the screw rod 9, so as to further enhance the connection stability between the support plate 4 and the bottom plate 3.
