Frame collides, and causes rotary movement that can not be normally carried out;In addition, the rear and front end in panel turnover machine is respectively arranged with fiber sensor,
It forms pcb board and prevents the protection mechanism that fractures, the fiber sensor of front end is set to the lower part of overturning material guide mechanism, and pcb board is through overturning
When material guide mechanism enters panel turnover machine and starts, fiber sensor starts timing after sensing pcb board, if the sensitive time is preset
It then represents that guide is normal, does not occur the situation of snap-gauge within 20s, guide exception is represented if being more than 20s if the sensitive time, having can
Situations such as snap-gauge can occur, at this time equipment alarm, when preventing the pcb board to be stuck between panel turnover machine and the feeding device of its front end, turn over
Trigger carries out turnover panel action, the situation for the pcb board that directly fractures, and the fiber sensor of rear end is set under overturning material guide mechanism
Portion, after the completion of pcb board overturning, when exporting tipper, which senses pcb board, if sensing pcb board
Time within preset 20s, then judges that pcb board transport is normal, if it exceeds 20s, then judge that pcb board transport is abnormal, equipment
Alarm prevents tipper from the pcb board for being stuck in tipper rear end fractures when overturning next time, specifically:
The turning-over support mechanism of the present invention is used to support, overturns and limits fixed overturning material guide mechanism, turning-over support mechanism
Including two spaced stents, two stands are respectively arranged at the both ends of rack, on two stands respectively by the first bearing and
Second bearing sets turn drive motor and holds cylinder tightly, and turn drive motor is connected to overturning material guiding machine with holding cylinder tightly
The both sides of structure, and pass through shaft and connect with overturning material guide mechanism, overturning material guide mechanism is freely rotated around the shaft, turn drive motor
Driving overturning material guide mechanism overturns 180 °, is exchanged with the positive and negative for realizing pcb board on overturning material guide mechanism;Turn drive motor
Both sides are respectively arranged with two horizontally disposed positioning cylinders, after the completion of overturning, are started push rod insertion by two positioning cylinders
In in the location hole of overturning material guide mechanism side, horizontal direction is fixed on by material guide mechanism is overturn by location hole, prevents from overturning
Situations such as inclination that material guide mechanism is generated when overturning error, avoids causing pcb board normal because of overturning material guide mechanism inclination
The situation of transport;Cylinder is held tightly by the way that semicircular holding seat is driven to rotate, and will be located at and hold tightly in seat and with overturning material guiding machine
The cylindric connector of structure side connection is held tightly, is prevented after the completion of overturning, and overturning material guide mechanism influences to generate because of its own gravity
It tilts, holds cylinder tightly and dual anti-rotation mechanism is formed together with positioning cylinder, assembly precision is effectively ensured;In addition, in two stands
Lower part be both provided with lift cylinder, the output terminal of lift cylinder extend through upward stent top plate be connected to the first bearing with
The bottom of second bearing, lift cylinder the first bearing of driving and second bearing before preparing to overturn drive entire overturning material guide mechanism
It moves upwards, to avoid in switching process, when the half for overturning material guide mechanism length is more than its bearing height and machine
Frame collides, and leads to not situation about normally overturning.
The overturning material guide mechanism of the present invention combines overturning actual demand, devises double-deck material guide structure, the bilayer guide knot
It closes and includes upper and lower spaced upper strata transmission belt and lower floor's transmission belt, the clearance space between levels transmission belt is placed to be passed
Defeated pcb board, this kind of structure have been effectively ensured overturning material guide mechanism and have supported pcb board respectively in tow sides, and PCB is effectively ensured
The transmission of plate;In addition, being provided with block in clearance space between levels transmission belt, block is located at the one of clearance space
End, the other end is open architecture, and open end of the pcb board through clearance space enters in clearance space, until block is resisted, block
Horizontal limiting pcb board is act as, prevents pcb board from skidding off clearance space in switching process;In addition, the guide of overturning material guide mechanism
Frame uses the design structure that the first guide rack, the second guide rack and support plate are combined, the first guide rack and the second guide rack interval
Setting, upper strata transmission belt and lower floor's transmission belt are arranged at intervals at the medial surface of the first guide rack and the second guide rack up and down respectively,
And connect respectively by the second drive link and the first drive link with being set to the guide driving motor of the first guide rack lower part, pass through
Guide driving motor drives upper strata transmission belt and lower floor's transmission belt to travel forward, and completes the transport of pcb board;In addition, the present invention
Interval adjustable structure design is used between first guide rack and the second guide rack, it is ensured that the fortune of the pcb board of different in width
It is defeated, equipment interoperability is improved, spacing adjustable function adjusts component by spacing and realizes, spacing adjustment component is set to second and leads
Between rack and support plate on the outside of the second guide rack, including electronic adjustment and two ways is manually adjusted, passes through tune respectively
The first screw and the second screw that whole motor and handwheel drive are set in the first guide rack and the second guide rack rotate, second
Bar and the second screw, which then drive, is arranged on it and is fixed on first seat in the second guide rack and second seat along first
Bar and the second screw move along a straight line, and the second guide rack is driven to move along a straight line relative to the first guide rack, realize the first guide
The adjustment function of spacing between frame and the second guide rack, support plate for fixed adjustment motor, between support plate and the second guide rack between
Every setting, the first screw and the second screw are extended to through the second guide rack on the outside of support plate respectively, and the first screw outer end is fixed with tune
Whole drive, the part between support plate and guide rack are equipped with adjustment driving wheel, and adjustment motor is by adjusting drive band
Dynamic first screw and adjustment driving wheel rotation thereon, adjustment driving wheel are set to by adjusting synchronous belt drive on the second screw
The rotation of adjustment follower, it is achieved thereby that the first screw and the second screw are synchronized with the movement, the second guide rack of guarantee synchronizes flat
Quietly move along a straight line;In addition, connecting shaft and connector sleeve are respectively equipped in stent and the first guide rack, connecting shaft and connector sleeve difference
The output shaft of cylindric connector and turn drive motor that turning-over support mechanism is held tightly in seat is connected, is turned over so as to whole
Turn and hold tightly.
The embodiment of the present invention only introduces its specific embodiment, does not lie in and limits its protection domain.The skill of the industry
