Electronic device and printed circuit board testing method

摘要

An exemplary printed circuit board testing method includes determining whether there is an open shielding box every a time interval. The method then transmits a first control signal including a first predetermined path to a robot when there is an open shielding box. Next, the method obtains an image captured by a camera and recognizes a unique identifier of a to-be-tested PCB in the obtained image. The method then determines a second predetermined path corresponding to the determined open shielding box, and transmits a second control signal comprising the determined second predetermined path to the robot. Next, the method closes the determined shielding box when a duration after transmitting the second control signal reaches a predetermined time, and controls a testing software to test the to-be-tested PCB, to generate a testing result corresponding to the unique identifier of the to-be-tested PCB.

主权项

1. An electronic device connected to a plurality of shielding boxes, a robot, and a camera, each of the shielding boxes capable of receiving a to-be-tested printed circuit board (PCB), each of the shielding boxes and each of the PCBs respectively comprising a unique identifier, the electronic device comprising:
a storage system storing a first predetermined path, the unique identifier of each of the shielding boxes, and a plurality of second predetermined paths each corresponding to one of the shielding boxes; the first predetermined path indicating a path from a depot storing a plurality of to-be-tested PCBs to a preset position in front of the camera; the unique identifier of each of the shielding boxes capable of being marked to identify that the shielding box corresponding to the marked unique identifier is open; each of the second predetermined paths indicating a path from the preset position in front of the camera to the corresponding shielding box; a processor; one or more programs stored in the storage system, executed by the processor, the one or more programs comprising:
a determining module operable to determine whether there is an open shielding box every a time interval;a first control module operable to transmit a first control signal comprising the first predetermined path to the robot when there is an open shielding box, to control the robot to carry the to-be-tested PCB from the depot to the preset position in front of the camera along the first predetermined path;an image analyzing module operable to obtain an image captured by the camera, recognize the unique identifier of the to-be-tested PCB in the obtained image, and transmit the recognized unique identifier of the to-be-tested PCB to a testing software;a second control module operable to determine the second predetermined path corresponding to a marked unique identifier of the shielding box, and transmit a second control signal comprising the determined second predetermined path to the robot, to control the robot to carry the to-be-tested PCB whose image has been captured by the camera from the preset position in front of the camera to the open shielding box along the second predetermined path; anda testing module operable to close the determined open shielding box when a duration after the second control module transmits the second control signal reaches a predetermined time, and control a testing software to test the to-be-tested PCB, to generate a testing result corresponding to the unique identifier of the to-be-tested PCB.
