Embodiment
For the ease of those skilled in the art's understanding, below in conjunction with embodiment and accompanying drawing the present invention is further described, the content that execution mode is mentioned not is to qualification of the present invention.
Extremely shown in Figure 6 like Fig. 1; A kind of special-shaped element inserter; Comprise frame 1, be arranged at vibrating feeder 2, slab feeding mechanism 3, feed mechanism 4 and the head aspiration mechanism 5 of frame 1; What slab feeding mechanism 3 comprised the lifting platform 31 that is movably set in frame 1 and was arranged at lifting platform 31 send panel guide 32, and frame 1 is provided with and drives first driving mechanism that lifting platform 31 moves up and down, said feed mechanism 4; Comprise guide rail holder 41 that is arranged at frame 1 and the long guideway 42 that is arranged at guide rail holder 41; The bottom of long guideway 42 is provided with arc-shaped guide rail 43, and dock with the bottom of long guideway 42 upper end of this arc-shaped guide rail 43, and the top of guide slot of arc-shaped guide rail 43 is equiped with guide rail press strip 44; The bottom of said arc-shaped guide rail 43 is provided with mobilizable feeding slide block 45, and this feeding slide block 45 offers groove 46; Also comprise and be used to drive second driving mechanism that feeding slide block 45 moves; Said head aspiration mechanism 5 comprises the elevating mechanism that is arranged at frame 1, the rotation angle mechanism that is arranged at frame 1, soup stick moving up and down 51 and is arranged at the suction nozzle 52 of the bottom of soup stick 51 that the upper end of this soup stick 51 is connected with elevating mechanism; The middle part of said soup stick 51 offers gas channel, and soup stick 51 is equiped with the adapter sleeve 53 of being convenient to connect gas-tpe fitting; Said rotation angle mechanism comprises bearing pedestal 54, the corner cover 55 that is installed in bearing pedestal 54 that is arranged at frame 1 and drives the motor 16 that corner cover 55 rotates that said soup stick 51 movable sets are in corner cover 55.
In plug-in unit processing; Earlier electronic component in bulk is supplied to feed mechanism 4 by vibrating feeder 2; By feed mechanism 4 electronic component is delivered to assigned address again, the electronic component that will be positioned at assigned address by head aspiration mechanism 5 again is drawn on the suction nozzle 52, this moment slab feeding mechanism 3 mobile PC B circuit boards; Make the electronic component that is adsorbed on the suction nozzle 52 be in the plug-in mounting position directly over after, accomplish plug-in units processing by head aspiration mechanism 5.
Carrying out feeding when work, electronic component is adjacent one by one, and gets in the guide groove of arc-shaped guide rail 43 along the guide groove of long guideway 42 successively, and at this moment, electronic component receives the effect of pushing of guide rail press strip 44 and rests in the guide groove of arc-shaped guide rail 43; Feeding slide block 45 moves under the effect of second driving mechanism backward; The groove 46 that is arranged at feeding slide block 45 also moves thereupon backward; When groove 46 move to the electronic component that is positioned at foremost under the time, this electronic component moves downwards down to the said groove 46 of embedding in the effect of pushing of guide rail press strip 44; Subsequently, feeding slide block 45 moves forward under the effect of driving mechanism, and the guide groove that this electronic component is transported to arc-shaped guide rail 43 is outside, so that the sucking action of head aspiration mechanism 5; After electronic component was taken away, feeding slide block 45 moved under the effect of driving mechanism backward, so that carry out feeding action next time.In the present invention; Said second driving mechanism once moves and only an electronic component is transported to assigned address, has improved the absorption accuracy of head aspiration mechanism 5 greatly, has reduced the difficulty of the work of drawing; Improved the feed efficient of inserter; Thereby improved the production efficiency of PCB circuit board, obviously progressive, practical.
Add man-hour carrying out plug-in unit, when electronic component be transported to soup stick 51 under the time, the gas channel to soup stick 51 middle parts begins air-breathing subsequently; Electronic component is being adsorbed under the effect of air-flow on the suction nozzle 52 that is arranged at soup stick 51 bottoms, and feeding slide block 45 withdrawal then is so that the transporting of next electronic component; Simultaneously also be convenient to carry out next step plug-in mounting; Soup stick 51 moves downward under the effect of elevating mechanism subsequently, so that carry out the plug-in unit action, and after electronic component is inserted to assigned address; Air-breathing stopping; Absorption affinity between electronic component and the suction nozzle 52 disappears, and soup stick 51 moves upward under the effect of elevating mechanism, so that carry out plug-in unit action next time.Head aspiration according to the invention mechanism is 5 simple in structure, it is firm to draw, and greatly reduces the manufacturing cost of equipment, reduced the damage to electronic component, and is practical.
Need to prove: the concrete shape of said suction nozzle 52 can be formulated according to the concrete shape of electronic component; When the alteration of form of the electronic component that needs plug-in unit; The suction nozzle 52 that only needs to change the respective shapes structure gets final product; Need not 5 integral replacings, reduce modification difficulty and repacking cost head aspiration mechanism.
