Description
Technical field
The utility model relates to a kind of negative-pressure adsorption nozzle unit, is specially the large suction suction nozzle of a kind of elasticity, belongs to semiconductor machining additional device technical field.
Background technology
At present, the application of suction nozzle is more and more extensive, especially, in the processing of semiconductor workpiece, generally all need suction nozzle to adsorb workpiece, its operation principle is, when suction nozzle is encountered by suction workpiece, workpiece two ends mineralization pressure is poor, and workpiece is just pressed in suction nozzle mouth, conversely when suction nozzle mouth negative pressure does not exist by nature, workpiece, due to the relation of gravity, has just fallen down and has departed from absorption.At present, suction nozzle is parts important in mounting device, and its quality directly decides the quality of mounting quality.But, current suction nozzle not only lacks flexibility buffer unit, easily when suction nozzle touches surface mount elements, surface mount elements is impacted, affects the serviceability of surface mount elements, and, existing suction nozzle due to contact area limited, absorption affinity is subject to certain restrictions, also easily cause absorption surface mount elements time, cause the local location stress deformation of surface mount elements, be not suitable for high-precision attachment process.
For solving above technical problem, the utility model provides the large suction suction nozzle of a kind of elasticity, by arranging quincuncial suction nozzle, the contact area of suction nozzle can be improved, making surface mount elements uniform force, being not easy distortion, by arranging buffer spring, suction nozzle can be avoided when contacting with surface mount elements, collsion damage is caused to surface mount elements, meanwhile, is provided with guide pillars and bushes, the uniformity that nozzle is subject to spring buffer power can be improved, improve paster quality.
Summary of the invention
For above-mentioned situation, for solving the defect of prior art, the object of the utility model just there is provided the large suction suction nozzle of a kind of elasticity, it comprises mount pad, buffer spring, guide pillar, guide pin bushing, suction nozzle body, suction nozzle, air flue and turnover tracheae, it is characterized in that, buffer spring is provided with between the rear end of described mount pad and described suction nozzle body, the two ends of described mount pad are fixedly installed described guide pillar, in described suction nozzle body, the position of corresponding described guide pillar is provided with described guide pin bushing, described guide pillar is slidably matched in described guide pin bushing, described suction nozzle is arranged on the front end of described suction nozzle body, air flue is provided with in described suction nozzle body, one end of described air flue is connected with described suction nozzle, the other end of described air flue is connected with described turnover tracheae, wherein, the shape of cross section of described suction nozzle is quincunx.
Further, as preferably, described buffer spring is disc spring.
Further, as preferably, the lower surface distance that the end of described guide pin bushing gives prominence to described suction nozzle body is 5-12mm.
Further, as preferably, the axis of described turnover tracheae becomes vertical with the air flue in described suction nozzle body and arranges.
Further, as preferably, the shape of described suction nozzle body is stepped.
The beneficial effects of the utility model:
The utility model provides the large suction suction nozzle of a kind of elasticity, by arranging quincuncial suction nozzle, the contact area of suction nozzle can be improved, making surface mount elements uniform force, be not easy distortion, by arranging buffer spring, suction nozzle can be avoided when contacting with surface mount elements, collsion damage is caused to surface mount elements, simultaneously, be provided with guide pillars and bushes, the uniformity that nozzle is subject to spring buffer power can be improved, improve paster quality.
