Technical field

The present invention relates to BGA devices to plant ball technical field, more particularly to a kind of clamping force adaptive ball grid array Device smooth transfer fixture.

Background technique

A kind of BGA Package (hereinafter referred to as BGA) High Density Packaging Technology, be welded in shell bottom surface it is many spherical Salient point realizes a kind of Advanced Packaging interconnected between packaging body and substrate by these solder bumps.BGA package can provide Than other dual-in-line packages (Dual in-line package) or four side pin flat packages (Quad Flat Package) More number of pins are accommodated, entire package bottom surface can be used to be distributed pin entirely, rather than only can around packaging body It is distributed pin, there can also be shorter average conductor length compared with the encapsulated type limited around pin, has more preferably high speed Efficiency.Therefore, bga device is widely used in SMT production mounting technology.Since BGA package solder joint is hidden in encapsulation originally Below body, welding quality is more difficult to control, and whens production and assembly, which is easy to appear failure welding defect, to be reprocessed.It is reprocessed into reduce This, failure welding BGA device is removed from printed board, is assembled into printed board just after planting ball again as a kind of necessity.With Toward BGA using plant billiard table reprocess plant ball exercise and make when, BGA device is subjected to soldered ball from planting billiard table and be transferred to heating zone with tweezers Heat cure, in transfer process, tweezers method of clamping is difficult to realize BGA device smooth transfer, causes on device substrate without heat Often there is soldered ball shifting phenomena in cured soldered ball, influences BGA device and plants ball quality.

Summary of the invention

Object of the present invention is to be directed to the above-mentioned problems of the prior art and shortcoming, it is simple, real to provide a kind of structure With property, strong, flexible and convenient operation, easy to carry, clamps force adaptive BGA device smooth transfer fixture.

To achieve the above object, a kind of technical solution of the present invention: clamping force adaptive BGA device smooth transfer Fixture, comprising: the hinged upper connecting rod 4 of ear is pitched by the trapezoidal hinged both sides of head of slide plate 2, and its passes through the narrow connecting rod 5 of Z-shaped transition and Z The double leval jib telescoping mechanism that the wide connecting rod 6 of shape transition forms, it is characterised in that: traveller 1 of the top with handle passes through slide plate 2 Central through hole and spring 3, be connected center linkage block 11, the Z-shaped narrow connecting rod 5 of transition and the wide connecting rod 6 of Z-shaped transition by respective end to Hinge hole rivets upper connecting rod 4 with rivet component 12, is connected respectively with left clamp 9, right clamping plate 10 with screw assembly 13；Left clamp 9 It is connected two sides lower link 7 with right 10 tail end of clamping plate by screw assembly 13, constitutes a two sides lower link 7 and hold the center that is connected altogether 11 both ends of linkage block, any adjustable side parallelogram telescoping mechanism altogether of angle, and the side parallelogram altogether is flexible It on the joint of the subtended angle opening of mechanism, is equipped with and connects firmly in left and right clamping plate 9,10 tail ends, there is opposite symmetrical anti-skidding grip block.

The present invention have compared with prior art it is below the utility model has the advantages that

(1) of simple structure and strong practicability, flexible and convenient operation are easy to carry.The present invention using slide plate and upper connecting rod, excessively Z-shaped cross Narrow connecting rod, the wide connecting rod of Z-shaped transition, lower link, left splint, right splint pass through handle, rivet, spiral shell around traveller, center linkage block Any adjustable double leval jib telescoping mechanism and any adjustable side parallelogram altogether of angle are flexible at an angle for screw assembly structure Mechanism.Traveller top handle can make operator extract movement；The traveller passes through slide plate and spring cooperates, and slide plate can be along cunning Column slides up and down；When pressing slide plate, slide plate is moved downward along traveller, so that angle at the arbitrary quadrilateral handle where slide plate Become larger, angle at the total side parallelogram handle of left and right clamping plate composition is driven to become larger, so that left and right clamping plate opens, device clamping In the process, clamping plate opens distance and gradually becomes smaller, until clamping device, in the process, and left and right clamping plate distance change, band in turn Angle becomes smaller at parallelogram handle where dynamic clamping plate, under spring force effect, pushes slide plate along traveller upward sliding, directly It is clamped to device and realizes clamping force adaptive locking；Operator is by handle, by BGA device smooth transfer to heating zone, so Slide plate is then pressed afterwards, by link transmission left and right clamping plate is opened, is realized the steady placement of device.

(2) present invention pitches the hinged upper connecting rod 4 of ear by the trapezoidal hinged both sides of head of slide plate 2 and its passes through the narrow company of Z-shaped transition The double leval jib telescoping mechanism that bar 5 and the wide connecting rod 6 of Z-shaped transition form, it is flexible using any adjustable side parallelogram altogether of angle The gripping width of mechanism can be adjusted according to size of devices, and realize device clamping force adaptive locking, and operator can lead to Cross the smooth transfer that handle realizes BGA device.BGA device is transferred to heating zone from billiard table is planted when avoiding plant ball The soldered ball of appearance shifts, and can guarantee that device is smoothly transferred to heating zone from plant billiard table, it is ensured that device plants ball precision.

(3) present invention holds 11 both ends of center linkage block that are connected using two sides lower link 7 altogether, and any adjustable side altogether of angle is flat Row quadrangle telescoping mechanism, it is ensured that the clamping face of left and right clamping plate is in parastate always, steady when keeping clamping；Parallel four On the subtended angle opening joint of side shape telescoping mechanism, it is equipped with and connects firmly in left and right clamping plate 9,10 tail ends, there is opposite symmetrical anti-slip clip Hold block, it is ensured that the reliable retention of device, chucking power are locked according to size of devices automatic adjusument, it is ensured that device quick and stable folder It holds.
