Description
Technical field
The utility model relates to electronic component process and assemble field, the LED feeder apparatus that especially a kind of polarity detects automatically.
Background technology
Along with science and technology development, the every industrial machine equipment of China also progressively moves towards automation, and special electronic application field development rapidly.
The electrode of most electronic component all has both positive and negative polarity on the market at present, and the lamp base of LED partly has the branch of both positive and negative polarity.When the inserter plug-in unit,, will cause printed panel to use if the polarity of LED lamp base is opposite.The polarity checkout gear of present most of LED all can only detect the polarity position, but the opposite polarity LED in the streamline can not be screened, and is unfavorable for follow-up plug-in unit operation use, and these device structure complexity, and the cost height is safeguarded inconvenient.
Chinese patent application, application number is CN201010138040.4, disclosed a kind of bulk light-emitting diode (LED) feeder comprises material folding pusher, material folding body, reshaping device, the first polarity testing agency, changement, the second polarity testing agency, downslide guide rail mechanism and feeding erect-position mechanism.Its detection is to rely on two to detect slide plates and clamp LED, allows then detect the lamp base part that the detector probe that voltage difference is arranged on the slide plate is touched LED from the side, if two probes have electric current to pass through, the polarity that LED be described is right, can be transported to the next process use.Detect because probe is a side direction, can only side direction clamp LED so detect slide plate.After detecting waste product, the detection slide plate can only be displaced sideways and open, allow LED fall.Like this, just need to drive and detect the mechanism that slide plate is displaced sideways, in addition, also need LED is delivered to the material folding assembly that detects slide plate from delivery track, so this discharged way is too complicated, cost height, poor reliability.
Because the contact area of probe is less relatively, so probe is difficult to guarantee contact with lamp base exactly, it is bad to detect effect, the false drop rate height; In addition, whether electric current is arranged by arriving that the corresponding instrument of needs is just seen, so this detection mode is not directly perceived.In order to increase the accuracy that probe contacts with lamp base, also established a reshaping device in this application, the lamp base of LED is carried out the straightening shaping by two pressing plates, so just increased the parts of entire machine, the production cost height, maintenance is inconvenient.In addition, because lamp base is made of metal, certain elasticity is arranged, under the compacting of short time, can not guarantee lamp base shaping success very, will impact follow-up detection like this, false drop rate can increase, and result of use is bad.
If do not have electric current to pass through between two probes, can there be two kinds of possibilities, the one, the polarity of this LED is not right, and the 2nd, this LED is a waste product.So documents turns to the LED that does not measure electric current after detecting for the first time by steering mechanism, deliver to the second polarity testing agency again and detect once more.After the commutation, the second polarity testing agency does not also measure electric current, and explanation is a waste product, and at this moment, two detect slide plate opens, and LED falls from blanking port, does not enter next process.Because changement complex structure, part are many, have just caused the high phenomenon of cost.In addition, adopt this mode, the material folding assembly need pick up LED, front and back need be walked five stations altogether, and its process action is loaded down with trivial details, and the mechanism that is associated is too many, there is sub-fraction to go wrong slightly and will causes whole detection to carry out, and too complicated, be not easy to produce and safeguard.
At present, inserter on the market mainly adopts vacuum slot to pick up electronic component, this inserter structure is often all very complicated, its maintenance cost is higher, enterprise is caused bigger financial pressure, and this inserter is the custom plug-in machine, its scope of application is narrower, also do not have LED custom plug-in machine at present, do not have to carry out the inserter that polarity detects yet.In addition, these inserter often are difficult to control to the grafting dynamics of special-shaped electronic component, cause the reduction of rate of finished products, cause waste.
Therefore, be badly in need of to occur that a kind of detection is effective, detection efficiency is high, maintenance cost is low, production cost is low, the scope of application is big, automatic insertion LED inserter accurately.
