Description
Technical field
The invention belongs to clean detection technique field, more particularly to a kind of suction nozzle cleans detection method.
Background technology
Product quality is improved, the target that the manufacturing cost Shi Ge enterprises of product are constantly pursued is reduced, is also to realize that enterprise is sent out
What is turned is basic.With the development of science and technology, the product of high-quality turns into the leading of market.In order to generate profit, ensureing product product
On the premise of matter, it is the effective means generated profit to reduce manufacturing cost.In current product manufacturing, product cost is constituted main
Have：1st, constant expense, such as equipment investment, place etc.；2nd, labour cost；3rd, Master Cost.Constant expense is with labour cost in recent years
Come in rising trend, and the product of high-quality is also required to be realized using high-end devices and the personnel being best suitable for, so, reduce into
This main means is to reduce the expense of material.
To realize the high-quality of product, the reduction of fee of material be not to buy low material, but in the fabrication process,
The manufacture loss of component is constantly reduced to realize successively decreasing for Master Cost.The mistake of component automatic welding is completed with high-speed equipment
Cheng Zhong, raising equipment production in sorption rate and be filled with rate, just can effectively control the loss of component.The sorption of influence equipment and it is filled with
Rate it is critical only that the suction nozzle rate of air circulation that equipment is used, the i.e. patency of suction nozzle.To ensure the unobstructed of suction nozzle, regularly clearly
It is a kind of maintaining method to wash, and is then one of the key link for the suction nozzle confirmation method after cleaning.
Traditional confirmation method is mainly artificial visual confirmation：By the suction nozzle after cleaning against light source, by the mesh of affirmant
Depending on carrying out the unobstructed confirmation of suction nozzle.Its drawback is：The influence of visual deviation and lamp, the suction after visually confirming
Mouth real machine percent of pass often occurs that high materials loss rate occurs when the suction nozzle real machine after confirming is produced about 70%.Need
The suction nozzle reproduction for more renewing, and abandoning material and can only do waste treatment before, virtually improve the finished product of product.It is solution
A kind of the drawbacks of certainly visually confirming, it is necessary to device that can substitute artificial visual confirmation, is realized using the automatic method for judging
100% merits and demerits rate after confirmation.
The content of the invention
In view of the foregoing defects the prior art has, detection method is cleaned this application provides a kind of suction nozzle, the purpose is to
Ensure it is confirmed it is qualified after suction nozzle, carry out real machine produce when do not produce spillage of material.
To achieve the above object, the technical scheme of the application use is：Suction nozzle cleans detection method, specifically includes：
S1:Suction nozzle suction nozzle to be detected being put on automatic rotational positioning mounting table places hole position；
S2:Automatic rotational positioning mounting table is rotated by driving stepper motor, and limit sensors determine rotation position, make
Each suction nozzle places hole position above corresponding green light source device；
S3:After green light source device is lighted, directly passed through by suction nozzle bottom, emerged on suction nozzle surface；
S4:2D cameras directly read the light source of microscope acquisition, after amplified certain multiple, in terminal imaging display dress
Showed on the display screen put；
S5:Image information is fed back into light sensation analysis inductor, light sensation analyzes inductor according to the suction nozzle area for setting
Threshold value carry out the division of non-defective unit, defective products；
Defective products result is input into corresponding PLC simultaneously, PLC lights the warning lamp of bad suggestion device.
Further, suction nozzle conversion is completed using the delay function of limit sensors, a suction nozzle detection time is set
It it is N seconds, motor is automatically rotated to next suction nozzle and is detected after N seconds.
Further, if the warning lamp of bad suggestion device is lighted, in next suction nozzle detection process is carried out, operator
Take bad suction nozzle away, then cleaned；Extracting position is put back to after cleaning.
Further, the method is not provided with automatic detection number of times, and circulation is detected；Until automatic rotational positioning mounting table
On all suction nozzles all detection it is qualified after, click on stop.
The present invention can obtain following technique effect due to using above technical scheme：The application instead of it is original according to
The suction nozzle detection for manually visually being carried out；The deviation during visually confirming and missing inspection are compensate for, is not only saved manually, together
When be that suction nozzle one-pass finished rate after detection is improved to 100%, fully met the demand of equipment production.Make the proportion of goods damageds of component
It is reduced to 0.23%.
