Background technology
In diode, most crucial parts are PN junction, be crystal grain (chip), need in enormous quantities the use when industrial production, at first large crystal grain is cut into to little crystal grain, then be put on suction disc and shake, make little crystal grain fall into the crystal grain fixing hole of suction disc, then transfer to next step and operated, and in this technique, when crystal grain rocks on suction disc, have a lot of crystal grain and be scattered in outside suction disc, need other equipment to be reclaimed, while producing the multiple grain diode; While in its next crystal grain fixing hole, needing a plurality of little crystal grain, rock medium and small crystal grain and easily overturn, cause the change of polarity, thereby cause produced diode to use; Finally, after crystal grain places in suction disc, shifted, during transfer, little crystal grain also can produce and rock, and causes above two kinds of problems, therefore needs a kind of more reasonably equipment.
Summary of the invention
For above deficiency, it is a kind of with transparent suction disc lid and the directional loading device vacuumized that the utility model provides, this device is by adding transparent suction disc lid, make crystal grain can not be scattered in outside suction disc in the process of rocking, coordinate and vacuumize simultaneously, make the crystal grain that enters the crystal grain fixing hole can upset not occur, thereby play the directed purpose of crystal grain (chip).
The utility model is achieved through the following technical solutions:
A kind of crystal grain orienting filling device, described crystal grain orienting filling device comprises suction disc and the transparent suction disc lid matched with suction disc, described suction disc is rectangular build, described suction disc is hollow-core construction, three limits of described suction disc upper surface are provided with baffle plate, described suction disc upper surface is provided with the crystal grain fixing hole to the suction disc inner recess, and described crystal grain fixing hole bottom is provided with the micropore for vacuumizing, and an end of described transparent suction disc lid is provided with sealing block.
One end of above-mentioned suction disc is provided with vacuum orifice, and because crystal grain fixing hole bottom is provided with micropore, micropore can not make crystal grain pass, and therefore can be vacuumized fixing to the above-mentioned crystal grain that enters the crystal grain fixing hole.
One end of above-mentioned vacuum orifice is arranged on an end of baffle plate.
The height of the height >=crystal grain of above-mentioned baffle plate, facilitate crystal grain to enter the crystal grain fixing hole.
Above-mentioned crystal grain fixing hole is cylinder type.
The height of the height >=crystal grain of above-mentioned crystal grain fixing hole.
The thickness of above-mentioned sealing block is identical with suction disc thickness, and thickness is identical, only the sealing block of transparent suction disc lid need to be placed into to the unbaffled side of suction disc alignment, and transparent suction disc lid can be positioned at desired location.
Above-mentioned transparent suction disc covers and is provided with alignment pin, and suction disc is provided with the location hole matched with alignment pin, for fixedly suction disc and transparent suction disc cover.
The beneficial effects of the utility model are: this device is by adding transparent suction disc lid, make crystal grain can not be scattered in outside suction disc in the process of shaking, coordinate and vacuumize simultaneously, make the crystal grain that enters the crystal grain fixing hole can upset not occur, thereby play the purpose of crystal grain orienting, the utility model is simple in structure, easy to use, effect is remarkable, is easy to promote.
