Description

Technical Field

[0001] The utility model relates to the technical field of 5G communication testing, in particular to a laser self-positioning and identification module. Background Technique

[0002] In the wireless communication industry, the mainstream antenna radio frequency performance testing methods mainly include anechoic chamber testing and coupled antenna testing. For the testing of 5G communication products, the device under test (DUT) needs to be placed in a microwave anechoic chamber for detection. For the shape positioning and identification of the DUT, the shape and size of the DUT are mainly automatically identified by laser. In view of this, the researchers in this field have designed a laser self-positioning and identification module. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a laser self-positioning and identification module.

[0004] The technical solution of the utility model is: a laser self-positioning and identification module, which includes a three-axis moving platform and a laser positioning and identification module. The three-axis moving platform includes two groups of Y-axis moving modules, an X-axis moving module mounted on the Y-axis moving modules, and a Z-axis moving module arranged at the output end of the X-axis moving module. The X-axis moving module is connected to the output end of the Y-axis moving module. The laser positioning and identification module is arranged at the bottom end of the Z-axis moving module through a connecting plate. The laser positioning and identification module includes a laser and an interference source. The laser is vertically downwardly arranged at the bottom end of the three-axis moving platform, and the interference source is arranged on the side of the laser. The output end of the interference source intersects with the laser emitted by the laser.

[0005] As can be seen from the above solution, the laser is used to emit laser downward towards the DUT. The three-axis moving platform is used to drive the laser positioning and identification module to move in three moving directions through the X-axis moving module, the Y-axis moving module and the Z-axis moving module. The interference source is used to interfere with the laser emitted by the laser.

[0006] The Y-axis moving module, the X-axis moving module and the Z-axis moving module all include a driving motor, a slide rail and a slider slidably matched with the slide rail. The driving motor is arranged at the end of the slide rail, and the slider is connected to the output end of the driving motor. The X-axis moving module is connected to the output end of the Y-axis moving module through a connecting frame. Thus, the connecting frame is used for connecting the X-axis moving module above the Y-axis moving module, and the driving motor is used to drive the slider to slide on the slide rail to achieve movement.

[0007] The laser positioning and identification module is arranged at the bottom of the connecting plate through a connecting component. The connecting component includes a mounting base, a side plate, and a bottom plate perpendicular to the side plate. The mounting base passes through the bottom of the connecting plate, and the side of the mounting base is connected to the connecting plate through a locking member. The laser is fixedly connected to the outside of the side plate, and the interference source is fixed to the bottom end of the bottom plate through a crank arm block. It can be seen that the locking member is used to lock and limit the mounting base and the connecting plate laterally, realizing the fixed installation of the laser positioning and identification module at the bottom of the connecting plate. The crank arm block is used to form a specific angle between the interference source and the laser, so that the output end of the interference source interferes with the laser.

[0008] The interference source includes a transmitting part and an interference part arranged at the output end of the transmitting part. There is a specific included angle between the transmitting part and the laser. The end of the interference part intersects with the laser emitted by the laser emitting part. It can be seen that the transmitting part is used to emit the interference part, and the interference part intersects with the emitted laser, and its end blocks the emitted laser signal to form interference.

[0009] The outer side of the three-axis moving platform is covered with wave-absorbing cotton through an anti-slip frame. It can be seen that the wave-absorbing cotton is used to absorb electromagnetic waves, which is convenient for communication testing in the shielding box. Description of the Drawings
