Description
Technical field
The utility model relates to manipulator field, and the transverse direction particularly related to for the punch press of FPC blank operation of arranging in pairs or groups moves material blanking manipulator.
Background technology
In current wiring board industry, especially FPC (being also referred to as FPC), has a procedure to be die-cut wiring board profile, is also referred to as stamping-out in row.The mode generally adopted in industry is one man operation punch press, processes wiring board profile by die-cut, and this mode has the advantages such as production efficiency is high, cost is low, uniformity is good.But Problems existing is that labour intensity is large, industrial injury risk is high, labour intensity is high, personnel are unstable.Along with expanding economy, the continuous rising of human cost and falling sharply of experienced operator, become the major issue of restriction FPC industry development.
Not long ago, applicant successfully develops a full-automatic gouging machine tool hand (patent No.: ZL201120389386.1) for this present situation, people's multi-machine operation pattern can be realized, solve the problems such as above-mentioned fatigue resistance is large, industrial injury risk is high, labour intensity is high, personnel are unstable, the equipment produced by implementing this patent had sold hundred, for numerous FPC producers adopts.This kind of type is because take into account the many-sides such as operation facility, the scope of application, material mode is moved before and after have employed, realized by counterdie turnover: counterdie runs to outside by servo screw body, feed in outside, after charged, counterdie is driven by screw mandrel and runs immediately below the patrix of inner side, and punch press matched moulds is die-cut.The repetitive positioning accuracy of this kind of mode to counterdie proposes high requirement, if repetitive positioning accuracy is not enough, will causes upper and lower mould Fast Wearing, even scrap; And flush shear force acts directly on movable lower mold mounting plate, also proposes high requirement to this block of material---shock-resistant, indeformable; Also have a bit, need the special cast iron plate of customization to change the original cast iron plate of punch press for installing screw mandrel slide rail etc., and this block casting iron plate needs has the higher depth of parallelism and surface smoothness, and need that there is enough impact strengths.
Because what time above, cause this blanking manipulator cost higher, portions of client wishes the solution that cost is cheaper.
Later stage has producer to develop Simple manipulator accordingly, it is die-cut that mode changes transverse shifting into, each assembly is directly contained on punch press body, cost significantly reduces really, but there is following defect: 1, because manipulator Traverse Displacement Unit is directly contained on punch press, cause the cantilever of loading and unloading paw installation sucker long, again because space constraint, structure is difficult to avoid causing shake because cantilever is long, finally causes fluctuation of service; 2, paw lifting adopts air cylinder driven mode, can only realize the operation of point-to-point transmission, when counterdie height changes, can only adapt to, make troubles to operation by means of the length of the screw below manual adjustments cylinder; 3, because paw lifting adopts air cylinder driven mode, cause suction nozzle to regulate narrow space, be difficult to the suction nozzle of tackling compared with complex product and regulate location, affect the adaptability of board; 4, because each assembly needs on-the-spot punching and punch press separate connection, installation and debugging and punch press maintenance is not easy to; 5, when drift keeps in repair, need each assembly to take apart separately, re-assembly examination again, need professional to be competent at after maintenance, use and maintenance work in the future of giving is made troubles.
