Abstract
The invention discloses an eutectic pressure accurate regulating mechanism which is used for solving the problem that the welding pressure regulating accuracy of the traditional press welder is poor. The eutectic pressure accurate regulating mechanism comprises a rack, a left bearing support (6), a right bearing support (6), a long-handle rotating shaft (11) and a transverse connecting plate (10), wherein a lead screw (9) and a screw weight block (8) are arranged on the rear end face of a tail cross bar of a long handle (12) in the shape of a Chinese character 'gong', a T-shaped nose connecting block (3) is arranged on the front end face of a head cross bar of the long handle (12) in the shape of a Chinese character 'gong', the head part of the T-shaped nose connecting block (3) is connected with the front end face of the head cross bar of the long handle (12) in the shape of a Chinese character 'gong' by virtue of a bolt, the tail of the T-shaped nose connecting block (3) is extended into a notch between two head parts of a Y-shaped suction nozzle connecting block (2) and is penetratively connected with the head block of the Y-shaped suction nozzle connecting block (2) by virtue of a rotating shat, and a suction nozzle cover (13) and a suction nozzle (1) are arranged at the tail part of the Y-shaped suction nozzle connecting block (2). The eutectic pressure accurate regulating mechanism disclosed by the invention has the advantages of simple structure and good continuity in welding and regulating.
Description
Technical field
The present invention relates to the pressure regulating mechanism in a kind of press welder, the mechanism of particularly a kind of press welder employed adjusting welding eutectic pressure when the eutectic welding operation of carrying out chip and pedestal.
Background technology
[0002] press welder mainly is to be applied in little assembling device chip and pedestal carried out the eutectic welding, and the Device Host head will be realized the motion of above-below direction, in welding process, realizes the welding of chip and pedestal through exerting pressure.In welding process, if making, the too little or inhomogeneous meeting of applied pressure produces space or rosin joint between chip and the substrate, if pressure is excessive, then can produce fragment.
At present, this kind equipment mainly is to regulate through compression spring to the adjusting of pressure, exists welding pressure to regulate poor continuity, and welding pressure is regulated the problem of control accuracy difference.
Summary of the invention
The invention provides the accurate governor motion of a kind of eutectic pressure and solved the welding pressure adjusting poor continuity that prior art exists, welding pressure is regulated the problem of control accuracy difference.
The present invention overcomes the above problems through following scheme:
The accurate governor motion of a kind of eutectic pressure; Comprise frame, left and right sides diaxon bearing, long handle rotating shaft and horizontal connecting plate; Horizontal connecting plate and left and right sides diaxon bearing are formed door font support body, and the long handle rotating shaft is arranged between the two bearings on the left and right sides diaxon bearing in the font support body, and left and right sides diaxon bearing and frame are fixed together; In the afterbody cross bar of I-shaped long handle, be provided with through hole; I-shaped long handle through the through hole that is provided with in the afterbody cross bar and the cross-under of long handle rotating shaft together, the rear end face of the afterbody cross bar of I-shaped long handle is provided with leading screw, on leading screw, is movably set with the screw balancing weight; The front end face of the head cross bar of I-shaped long handle is provided with T font head contiguous block; The head of T font head contiguous block links together through the front end face of the head cross bar of bolt and I-shaped long handle, and the afterbody of T font head contiguous block extend in the breach between two header block of Y font suction nozzle contiguous block, and two header block cross-under through a rotating shaft and Y font suction nozzle contiguous block together; Afterbody at Y font suction nozzle contiguous block is provided with the suction nozzle cover, in the suction nozzle cover, is set with suction nozzle.
Montant middle part at I-shaped long handle is provided with bracing frame, and bracing frame is provided with cam.
The present invention is novel in design, and simple in structure, the welding pressure adjustable range is big, and the continuity of adjusting is good, and cost performance is high.
Description of drawings
Fig. 1 is a structural representation of the present invention.
