The invention discloses an automatic
assembly line type cellphone online testing method, and the method comprises the following steps: (1), implanting
testing software in a plurality of to-be-tested cellphones; (2), preparing an automatic
assembly line type cellphone online testing
system; (3), enabling the to-be-tested cellphones to be placed on a testing carrier, wherein the to-be-tested cellphones is driven by the upper conveying rail to move to a testing
machine bench along with the testing carrier; (4), enabling a PC to transmit an AT instruction to built-in
testing software in the to-be-tested cellphones through a testing communication model, enabling a PLC to drive the testing
machine bench to carry out one operation for the to-be-tested cellphones according to the content of the AT instruction, and enabling the
testing software to test the functions of the to-be-tested cellphones; (6), taking out the to-be-tested cellphones after the detection is finished, enabling the testing carrier to move to the lower end of a feeding bench along with a lower conveying rail, and enabling a front end lifting platform to lift the testing carrier back to the feeding bench. The method is quick and accurate in testing instruction transmission, improves the testing efficiency, is quick and precise in testing, and reduces the testing time.
