Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is further illustrated.
Embodiment:
A kind of intelligent welding automatic production line, comprising:
AOI device, for for carrying out image photographic to pcb board, and being formed comparison with non-defective unit pcb board image, being calculated the coordinate of bad bump by software;
Select spraying machine, for spraying scaling powder to the bad solder joint on pcb board;
Select tin soldering machine, for carrying out correction scolding tin to bad solder joint;
Conveyer, for being transferred to AOI device successively, selecting spraying machine and select tin soldering machine by pcb board.
In the specific implementation, pcb board is transferred to AOI device, selects spraying machine and select tin soldering machine by conveyer successively.Pcb board is first transferred to the detection position of AOI device by conveyer, AOI device carries out image photographic to pcb board and non-defective unit pcb board image forms comparison, the coordinate of bad bump is calculated by software, and the coordinate of bad bump given selection spraying machine and select tin soldering machine, select spraying machine and selection tin soldering machine to carry out spraying scaling powder and scolding tin respectively according to the bad solder joint of the coordinate of bad bump.This production line forms full-automatic structure, substitutes and manually repairs, full process automatization process, improves yields and formation efficiency.AOI device is optical detector, and conveyer can be belt conveyer, chain transmission device etc.Pcb board, when carrying out image photographic, is moved to desired location by fixture by AOI device, as desired location is provided with sensor, then stops mobile, locate for auxiliary photo-taking when fixture moves to sensing station; When acquisition pcb board image, carry out division coordinate to pcb board image, and compare with non-defective unit pcb board image, the image of non-defective unit pcb board can first be stored in the memory of AOI device; Find out bad bond pad locations by software and calculate the coordinate of bad solder joint, then the coordinate of bad solder joint being sent to and select spraying machine and select tin soldering machine.
Further, described AOI device is provided with image capturing system, image capturing system stores non-defective unit pcb board image, image capturing system is compared to the pcb board image gathered and non-defective unit pcb board image, coordinate division is carried out to the pcb board image gathered simultaneously, when bad solder joint appears in pcb board, image capturing system carries out coordinate mark to the bad solder joint on pcb board, records the coordinate of bad solder joint; Described AOI device is also provided with sender unit, and the coordinate information of pcb board picture and bad solder joint externally sends by sender unit, and described selection spraying machine and selection tin soldering machine are equipped with signal receiving device.Select spraying machine to carry out spraying scaling powder to bad solder joint, select tin soldering machine to carry out scolding tin to bad solder joint.
In the technical program, be provided with image capturing system by AOI device, this image capturing system carries out coordinate division to pcb board picture, and compares with non-defective unit pcb board image, finds out bad solder joint; Bad bond pad locations is corresponded in the coordinate of picture, bad solder joint can be oriented accurately, and the coordinates transmission of bad solder joint given selection spraying machine and select tin soldering machine, select spraying machine to realize man-to-man scaling powder spraying according to coordinate data to bad solder joint, select tin soldering machine also according to coordinate data, bad solder joint to be realized to man-to-man scolding tin, drags tin.In the specific implementation, sender unit, signal receiving device can be all WiFi device, arrange a WiFi router on a production line; By WiFi router, signal is forwarded.Conveniently coordinate value shares, and AOI device, selection spraying machine, selection tin soldering machine all adopt identical workbench, namely adopt identical control pcb board motion.
