Compared with prior art; Can realize the synchronous spraying printing mark code when electric logging equipment testing circuit board that adopts the present technique scheme to provide is qualified; Promptly utilize same equipment to accomplish electrical measurement and spray printed mark sign indicating number; Avoid the people for obscuring defective circuit board and qualified circuit board thus, and enhance productivity greatly.
Description of drawings
Fig. 1 is the structural representation of the electric logging equipment that provides of present technique scheme implementation example.
Embodiment
Below will combine embodiment and accompanying drawing that the electric logging equipment that the present technique scheme provides is described in detail.
See also Fig. 1, the electric logging equipment 100 that present technique scheme implementation example provides comprises board 10, electrical measurement portion 20, feeding unit 60, sensing member 30, control part 40 and coding portion 50.
Sensing member 30 is fixed in the installed surface 112 of top board 11; And between defective plate rest area 13 and on-gauge plate rest area 14; So that follow-up in the process that will be delivered to on-gauge plate rest area 14 and defective plate rest area 13 by electrical measurement portion 20 through the circuit board after electrical measurement portion 20 test this circuit board of sensing, and this sensing result transferred to control part 40.Sensing member 30 can be this area optoelectronic switch or imageing sensor commonly used.
Fixture 15 is fixed in coding portion 50, and its nozzle is relative with sensing member 30, its qualified circuit board of electrical measurement when electrical measurement portion 12 is delivered to predetermined coding position according to the instruction of control part 40 directly at circuit board surface spray printed mark sign indicating number.Coding portion 50 can be this area ink gun commonly used.
When using the electric logging equipment 100 electrical measurement circuit boards that present embodiment provides; If circuit board is after 20 electrical measurements of electrical measurement portion are characterized by on-gauge plate, control part 40 is opened sensing members 30, when feeding unit 60 should qualified circuit board be delivered to sensing member 30 present positions; Sensing member 30 senses this circuit board; And sensing result is delivered to controller 40, and 50 codings of controller 40 control coding portions are in this circuit board surface, and feeding unit 60 places on-gauge plate rest area 14 with this circuit board.If circuit board is indicated as defective plate through electrical measurement, control part 40 is closed sensing member 30, and the portion of coding simultaneously 50 does not operate, and feeding unit 60 directly is delivered to defective plate rest area 13 with this circuit board from electrical measurement portion 20.
In addition; The control part 40 of present embodiment can be provided with the computer program that prelists of mark code; This computer program is given a unique mark code to the qualified circuit board of each electrical measurement, controls coding portion 50 thus at this unique mark code of the qualified circuit board surface spray printing of each electrical measurement.The structure of the electric logging equipment 100 of present embodiment is not limited to this, as fixture 15 is not set, and coding portion 50 is directly fixed on installed surface 112, and makes its shower nozzle along the gravity direction setting.Control part 40 can be located at top board 11; And adopt other any conventional means of this area to fix; Position relation between electrical measurement portion 20, defective plate rest area 13, fixture 15 and the on-gauge plate rest area 14 can be provided with by other form; As long as detecting part 30 and coding portion 50 are located between electrical measurement portion 20 and the on-gauge plate rest area 14, can the sensing electrical measurement qualified circuit board also is synchronized with this circuit board surface coding and gets final product.Especially, sensing member 30 can be opened running always, though promptly control part 40 links to each other with sensing member 30; Whether do not operate but do not control sensing member 30, at this moment, if the electrical measurement result of electrical measurement portion 20 is indicated as on-gauge plate; Electrical measurement portion 20 is with this electrical measurement result transmission to control part 40; In case feeding unit 60 transfers to the zone that sensing member 30 can sense with this circuit board, sensing member 30 transfers to control part 40 with sensing result, and control part 40 control coding portions 50 are in this qualified circuit board surface spray printed mark sign indicating number.In addition; Control part 40 can not link to each other with electrical measurement portion 20; Accordingly, defective plate rest area 13 is not located between electrical measurement portion 20 and the on-gauge plate rest area 14, at this moment; Feeding unit 60 only will be delivered to on-gauge plate rest area 14 from electrical measurement portion 20 via sensing member 30 through the qualified circuit board of electrical measurement portion 20 electrical measurements, realize this qualified circuit board of a sensing thus.
