Description
Technical field
The present invention relates to LED chip mounter technical field, refers in particular to a kind of feed device in LED chip mounter.
Background technology
LED chip mounter, be SMT production line in capital equipment, also known as LED surface mounting system or LED placement equipments, utilize control system driving mounting head motion, original paper is drawn at feed by suction nozzle, Surface Mount Component is properly placed on PCB pads, completes attachment.The feed device of traditional large LED chip mounter mainly will attachment component is accurate, is continuously sent to LED chip mounter feeding position, then feeding feeding is carried out by suction nozzle, but traditional feed device has the disadvantage that：1）At feeding and at feeding relatively far apart, each feeding feeding suction nozzle is required for moving a considerably long segment distance, inefficient；2）When web feed mounts component, charging aperture relies on machinery positioning, it is desirable to which precision is higher, and prior art is difficult to accomplish；3）Complicated, economy is not high.
Production of the attachment efficiency of LED chip mounter for LED chip mounter is particularly significant, traditional LED chip mounter is equipped with suction nozzle, carrying out suction nozzle when feeding operation and feeding operate every time all needs to move a considerably long segment distance, so causes to mount inefficient, it would be highly desirable to further improve.
The content of the invention
The defects of it is an object of the invention to overcome existing LED chip mounter feeding loading efficiency not high, propose a kind of more efficiently succinct LED chip mounter feed device.Technical problem to be solved is without feeding on suction nozzle to charging tray and to feeding on pcb board, and directly LED lamp bead is sent on pcb board and corresponds to welding position, completes the attachment of component.Due to not needing this device of suction nozzle so that feed device is more succinct, improves attachment efficiency.
The object of the invention to solve the technical problems is realized using following technical scheme, according to a kind of LED chip mounter feed device proposed by the present invention, it includes charging tray storage and material strip feeding device, upper scrap belt storage device, lower scrap belt storage device, LED lamp bead reverse side conveying device and photoelectric detector.The charging tray storage and material strip feeding device transport track and driver including charging tray holder, material strip, and its front-right is provided with scrap belt storage device, and lower right is provided with lower scrap belt（Protective film）Storage device, it is respectively used to store up scrap belt and lower scrap belt.It is to stand upside down to place that material strip is transported in track in material strip, when driver provides a trigger pulse, charging tray stores and material strip feeding device reception signal starts the lattice of material conveying tape travel one, upper scrap belt storage device and lower scrap belt storage device are driven the upper scrap belt of traction and lower scrap belt movement same distance simultaneously, upper scrap belt is with being placed with LED lamp bead reverse side conveying device immediately below the lower scrap belt place of separation, the lower scrap belt on material strip（Protective film）Due to being lifted a lattice so that the LED lamp bead in that lattice loses protection and fallen into LED lamp bead reverse side delivery track.The distance that LED reverse side delivery track separates place with upper and lower scrap belt is very short, and LED lamp bead will not be overturn after falling into track, and lamp bead scolding tin is face-up, lights face-down.
The present invention is solved its technical problem and is also realized that, according to a kind of LED chip mounter feed device proposed by the present invention, it includes above-mentioned LED lamp bead reverse side conveying device and photoelectric detector using following technical scheme.The LED lamp bead reverse side conveying device includes LED lamp bead reverse side delivery track and ultrasonic oscillator, the front of LED lamp bead reverse side delivery track is semicircle, ultrasonic oscillator and two photoelectric detectors are provided with the right of it, extending small pin is provided with the middle part of track, an opening more bigger than LED lamp bead is respectively arranged with above and below track so that LED lamp bead can fall into and skid off track.When photoelectric detector one detects that LED lamp bead falls into LED lamp bead reverse side delivery track upper opening from material strip, ultrasonic oscillator starts to vibrate, LED lamp bead is promoted to be slided in smooth semicircular track, until being skidded off from the opening below semicircular track, fall exactly on pcb board at corresponding welding position；When photoelectric detector two detects that LED lamp bead skids off from track lower opening, turn off ultrasonic oscillator, whole LED reverse side delivery track is to right translation suitable distance, small pin is allowed just to be directed at the LED lamp bead being just slipped on pcb board, and lamp bead is compressed downwards, whole track goes back to origin-location to left again, continues to convey next LED lamp bead.
The present invention is solved its technical problem and also realized using following technical scheme, according to LED lamp bead reverse side delivery track proposed by the present invention, the rectangular cross-section of the track, it is long and wide only more slightly larger than LED lamp bead, so when LED lamp bead is moved in reverse side delivery track, it will not overturn, will not also swing to, but moved along Satellite Orbit Smoothing.When lamp bead has just fallen into track, scolding tin is face-up, lights face-down, when lamp bead skids off track, because the movement locus of LED lamp bead in orbit is semicircle, lamp bead just reverse side, scolding tin is face-down, it is luminous face-up, then fall on pcb board and correspond at welding position, meet that attachment requires.
From above technical scheme, a kind of LED chip mounter feed device of the present invention at least has following advantages：Compared with traditional LED chip mounter manually collects upper scrap belt and lower scrap belt, the device energy automatic conveying and collection material strip, upper scrap belt and lower scrap belt, function are more perfect.Because there is provided LED lamp bead reverse side conveying device, LED lamp bead falls into delivery track and reverse side can fall on pcb board and correspond at welding position automatically after half circular motion, compared with the feed device of traditional LED chip mounter, a LED lamp bead need not often be mounted, suction nozzle will move a segment distance to material strip feeding and to this operation of feeding on pcb board, feeding time and manufacturing cost are saved, attachment efficiency is also higher.Track desigh can make in the motion process of LED lamp bead in orbit into semicircular be advantageous in that, solder side is exchanged mutually with light-emitting area, meet the attachment requirement of lamp bead.In addition, in order to prevent LED lamp bead from falling into transfixion after LED lamp bead reverse side delivery track, it is specially provided with a ultrasonic oscillator and promotes LED lamp bead to be moved in smooth track, so as to complete the attachment of component.
