Description
Technical field
Involved in the present invention is a kind of method and adsorption structure of automatic absorption nut, and it relates generally to a kind of adsorption method and structure, especially method and the structure that nut is adsorbed.
Background technology
On circuit board, follow at present the mode of various nut, mostly be with then assembling of surface mounting technology, its technology is with the nozzle structure generation absorption affinity of bleeding, use this nut is attracted to adhere to, and after aligning predetermined welding position, be released on the circuit board, the circuit board that will place all multicompartments more already is welded in each assembly and nut on the circuit board with surface mount via the solid welding of tin stove.
The technology of at present general prior art such as Republic of China's patent announcement number the 509294th " can utilize the information of automation facility absorption and the bolt structure of communication articles for use ", notification number M248188 " nut insert that is used for surface mount component ", notification number ground M248193 " is used for the capping of surface mount component " and connects a small wooden pile content and is all the hollow cylinder of nut for connecting, its central authorities offer a through hole, this through hole inner surface is formed with a screw thread: right, utilizing nozzle structure to adsorb above-mentioned nut when moving, can't adsorb owing to be subjected to the influence of through hole, Gu for overcoming the restriction that through hole causes absorption, the technology of being taked for have following several:
1, adds a closed component at an end of nut and temporarily be fixed on the nut, and contain an end face of whole nut and the hollow position that this through hole defines, make nozzle structure adsorb this closed component again, after treating that the nut solid welding is finished, again this closed component is removed;
2, in the hollow position that the through hole of nut defines, clog a closed component and adsorb for nozzle structure, treat that the nut solid welding is finished after, again this closed component is removed;
Right aforesaid way, on implementing, reality have its problem to exist, because then the number of the nut on circuit board is various, and, must additionally add a closed component for nut can be adsorbed, make material cost increase, moreover also also increased the work formality of adding and remove this closed component, and not only consuming time taking a lot of work, operating efficiency is poor, and accuracy and correctness also can't reach standard, are not inconsistent use in fact.
As No. 500197 " nut of tool blind hole " novel patent case of Chinese patent notification number, the technology that it disclosed is the hollow cylinder that belongs to non-perforation for this nut, its central authorities offer a blind hole, this blind hole internal surface is formed with a screw thread, and since its sentence nut attracted to adhere to for so this nozzle structure of blind hole can adsorb this blind hole smoothly, to overcome the restriction that aforementioned through hole causes absorption.
Described execution mode also has its problem to exist, since in blind hole, offer screw thread its to make yield relatively poor, and also can be residual in the blind hole, for forming the surplus bits of screw thread, when suction nozzle adsorbs this nut, also simultaneously residual surplus bits are attracted into, not only cause the absorption affinity of nozzle structure to reduce through accumulation, and then influence the installation of nut, also can cause this nozzle structure to damage what is more.
