Example two
In this embodiment, the execution component of the movable structure is used to move the connector component of the testing instrument, such as the thimble and the radio frequency testing head, so as to sequentially test each communication module in the PCBA. The method of the present embodiment may comprise the steps of:
s01, the control device obtains the initialized position information of the first communication module in the PCBA with a plurality of communication modules on the fixed station.

For example, if the distance between adjacent communication modules is d and the width of each communication module is e, the horizontal movement distance of the movable structure when testing a second communication module adjacent to the first communication module is d + e.
And S06, the control device sends a movement instruction carrying the horizontal movement distance to the movable structure, so that the movable structure moves based on the movement instruction, and the moved joint component corresponds to the position of the nth communication module in the PCBA.

In a specific implementation, an optical positioning component can be installed at a designated position of each jointed board PCBA, and an initial position is determined by the optical positioning component at a first communication module to be tested, so that the movement of the joint component is controlled.
The production flow in the prior art is that after the PCBA of the jointed board is finished, the jointed board is divided into single communication modules, and then the communication modules are calibrated and tested one by one, the problem of high labor cost exists in the process, and if the jointed board is to be modified into automation, only an expensive three-axis mechanical arm and a machine vision system can be used.
In the embodiment of the invention, the production flow is adjusted, after the PCBA of the jointed board is finished, the automatic jointed board calibration test is firstly carried out, and then the jointed board is divided into boards. Because the distance between the jointed boards is known and fixed, the cost for carrying out automatic reconstruction is very low, and the method can be realized by only adopting an XY sliding table assembly and a cylinder assembly, thereby better saving the cost.
