The limiter is used to realize limit fixation of the equipment to be tested on the carrier platform, and the laser recognition module is correspondingly arranged on the carrier platform to facilitate laser recognition and positioning of the equipment to be tested on the carrier platform, so as to identify the external dimensions of the equipment to be tested.

The Y-axis mobile module includes two sets of parallel Y-axis mobile frames, and the X-axis mobile module is located at the output end of the Y-axis mobile frames. Thus, the X-axis mobile module, Y-axis mobile frame, and Z-axis mobile module are used to drive the laser recognition module to achieve movement in three sets of axial directions.

[0007] The laser recognition module includes a laser, which is connected to the bottom of the Z-axis moving module via a mounting plate.

The transmission module includes a driving pulley, a transmission belt body and a driven pulley. The driven pulley is connected to the driving pulley through the transmission belt body. The driving pulley is connected to the output end of the second rotating motor. The supporting platform is coaxially connected to the driven pulley through a connecting shaft.

[0009] The position limiting member includes a plurality of suction cups disposed on the carrying platform, the suction cups being disposed upwards. It can be seen that the suction cups are used to adsorb the device under test on the carrying platform, thereby achieving position limiting and fixing of the device under test on the surface of the carrying platform.

[0010] The outer surfaces of the two-axis rotating platform and the three-axis movable platform are both covered with absorbing cotton. This shows that the absorbing cotton is used to cover the two-axis rotating platform and the three-axis movable platform to absorb electromagnetic waves, facilitating the use of the two-axis rotating platform and the laser positioning recognition module in a shielding box.
