METHOD AND APPARATUS OF STUD ARRAY UPSTAND SETTING

摘要

2137678 9400734 PCTABS00030 Apparatus and method of setting the upstand height of the studs (5) of an array (1) of studs used to form antenna panels is disclosed. The apparatus includes a transducer beam (10) having a row of spaced apart distance transducers (12). The apparatus also includes an actuator beam (22) having a row of spaced rotary actuators (26). The actuators (26) rotate the threaded studs (5) to raise or lower same until the corresponding transducer (12) indicates that the stud has achieved an intended height. Also disclosed is a method using an array of laser diodes (60), rather than the transducer beam (10), arranged at one end of the base plate (2) and an array of photodiodes (62) at the opposite end. Output (63) of the diodes (62) indicates the height of the studs (5).
