Description
Technical field
The utility model relates to Automatic laser field, specifically a kind of tin ball pump head for laser soldering.
Background technology
Common laser weld be by welded object through laser irradiate after, it is allowed to occur from the physical process being melted to recrystallization, term is referred to as " physical phase transition ", also include " alloy phase change " in its recrystallization process, even occur " chemical change " etc., the last welding body obtained, such Type of Welding is referred to as " laser welding weldering " by we, and welding mechanism is as follows:
Physical phase transition: solid phase → liquid phase → solid phase
Alloy phase change: for the welding of the first and second two kinds of different materials, often while thing phase change occurs, also will along with the generation of chemical phase transformation, as the alloying element in first object, when liquid phase occurs, combining of metallic bond will be produced with the carbon in second material, form a new molecular architecture, reconfiguring like this, will directly cause the mechanical performance after welding to change, as: change of fragility increase, welding stress, tensile strength etc.
Chemical change: two kinds of alloying substances via " solid phase → liquid phase → solid phase " and change in, probably can produce the compound made new advances, and new compound can solidify among last finished product, or become gaseous state to overflow, this is all possible, particular problem must be made a concrete analysis of, but inquires into category herein because exceeding, and does not allly repeat herein.
But, separately there is a kind of special welding, just can not use above-mentioned " laser welding weldering ", such as: superfine laser weld just can not use laser welding weldering, illustrates as follows:
There is the disk of a High Rotation Speed computer hard disc inside, side also has the scanner of a high speed, be used for reading and writing data, scanner is the precision optical machinery mechanism of a high speed swinging, the swing arm of scanning there is the flexible PCB that very little, its I/O, one end connects probe, the other end exports hard disk outlet to, and welding for flexible PCB here and probe, just can not weld with laser welding completely, not so, wire on the wire of flexible PCB and probe, can come to naught under powerful laser beam irradiation.Therefore, for this kind of meticulous laser weld, can only " laser soldering " be used, also known as " laser soldering ".
" laser soldering " primary stage is " laser scolding tin wire bond connects ", but the welding of this mode, spot size is wayward, and general solder joint is all somewhat excessive, does not reach the degree of meticulous welding.Proper is weld with the tin ball of a fusing, and Here it is " laser soldering ", and this method can be referred to as " ball bonding of laser tin ", also known as " weldering of laser molten drop ".
The diameter of tin ball is general all smaller, be applicable to doing superfine welding, tin bulb diameter includes ... Φ 0.3mm, Φ 0.4mm, Φ 0.45mm, Φ 0.5mm, Φ 0.55mm, Φ 0.6mm, Φ 0.76mm ... Deng equal-specification, the manufacture of tin ball is a kind of mature technology at present, therefore, do meticulous laser weld, meticulous laser weld can be carried out with the tin ball of a fusing completely.
" weldering of laser molten drop " operation principle: with laser fusion tin ball, to be power with certain air pressure spray the liquid tin ball of fusing simultaneously (drip in) on welded object, liquid tin ball will complete in solder within the extremely short time " infiltration " process, thus two objects are welded together.Facts have proved, " weldering of laser molten drop " is a kind of meticulous laser weld really, is adapted at high-tech area and does very meticulous welding.But carried out being separated and sorting by fine tin ball, and controlled to be pumped into laser nozzle medium to be welded, be one and be not too easy to thing, this mechanism, we are referred to as " tin ball pump head ".
The structure of existing disc type tin ball pump head is shown in Fig. 1, when rotating shaft 12 is rotated, rotating disk 1 synchronous axial system will be driven, and a point ball 1-B position delivered to by the tin ball deposited on rotating disk point of ball 1-A place, when this tin ball arrives 1-B position time, this tin ball will fall in nozzle 5 under gravity, wait laser irradiates, melted, in the moment of this tin ball of laser fusion, working gas will through gas blow pipe joint 7, transverse air channel 10, downward back taper air flue, the interior road of nozzle 5, rapidly the tin ball of fusing is blowed to soldered object below, thus complete welding.
Problem existing for this kind of mechanism:
The diameter of tin ball is general all smaller, and the diameter of tin ball will determine the thickness of rotating disk, in general, if the words of the tin ball with Φ 0.76mm, the thickness of rotating disk 1 will only have 0.8mm-0.9mm, this will cause this sheet parts manufacturing cost of rotating disk 1 high, in order to ensure the rigidity of mechanical strength and part, need to carry out intermediate heat-treatment, this will improve processing cost undoubtedly, and raising difficulty of processing, be difficult to ensure rotating disk two sides beat within design load, excessive because beat, rotating disk 1 will rub upper end cover 13 and bottom end cover 2, excessive friction will cause card ball to detect and be difficult to realization.
The processing cost being not only rotating disk 1 is high, and the upper end cover 13 matched with it, bottom end cover 2 all can improve machining accuracy, processing cost accordingly, could meet the running precision of rotating disk mechanism.Because rotating disk 1 is larger with the rubbing surface of upper end cover 13, bottom end cover 2, therefore, in order to ensure that the comprehensive gap after installing is in the state avoiding rubbing, so, mechanism is with regard to the artificial gap increased between rotating disk 1 and upper end cover 13, bottom end cover 2, but cross wide arc gap tin ball less than normal for dimensional tolerance to be stuck among upper and lower gap, cause failure mechanisms.Whenever so far, only have whole pump head is dismantled, cleans, ressembled adjustment.
In addition, rotating disk 1 is larger with the rubbing surface of upper end cover 13, bottom end cover 2, will, due to the composite factor manufactured, install, cause frictional resistance excessive, therefore, utilizes motor load curent change to judge that the function of card ball will be difficult to realize.

Because the quality comparation of tin ball is little, and can be adsorbed among tin ball reservoir 20-B ' because of frictional static, so, the longitudinal gas channel 18-B that the protection gas (nitrogen) with certain pressure sent here via the tin ball gas gas-tpe fitting 19 that blows off will pass through below rotor 18, enter the transverse air channel 20-A ' of rotor 20, after this strand of gas enters, can not to turn left advance, because left end is shut by end cover 16, therefore, this strand of gas orientation can only blow tin ball in tin ball reservoir 20-B ', this tin ball is forced to drop down to 22-A chute below, until arrive the tip of nozzle 21.
Be understandable that, rotor 20 has several transverse air channels 20-A (20-A '), with it the corresponding tin ball reservoir 20-B (20-B ') having quantity identical.
When tin ball reservoir 20-B moves to below rotor 20, now indicate with 20-B ' on Fig. 2, when tin ball reservoir 20-B ' aims at the falling sphere passage 18-C of outer sleeve 18, the respective transversal air flue 20-A (being now labeled as 20-A ' on Fig. 2) of rotor 20 is by the longitudinal gas channel 18-B below UNICOM's outer sleeve 18, this has also just connected the pressed gas from the tin ball gas gas-tpe fitting 19 that blows off, thus is blown off by the tin ball in tin ball reservoir 20-B ' rapidly.Rotor 20 turns over certain angle, the pressed gas in transverse air channel 20-A ', will automatically be cut off, thus also automatically stops blowing to tin ball reservoir 20-B '.
Referring to Fig. 2, rotor 20, when rotating, will drive end cover 16 synchronous axial system, and this will cause guide-lighting groove 16-A at a time could the fiber-optic sensor probe 32 of UNICOM's outer sleeve 18 both sides.Referring to Fig. 5, the detection light that the luminous point 32-A of fiber-optic sensor probe sends, by receive by the probe on opposite, this state only has a location point within the scope of 360 °, therefore, this location point will be used to the origin of coordinates of rotor 20 at circumferencial direction, for Automated condtrol.
Referring to Fig. 3, chute main body 22 and outer sleeve 18 are fixed together, the falling sphere passage 18-C that chute 22-A will be communicated with below outer sleeve 18, and tin ball slips and delivers to nozzle 21 by chute 22-A, and tin ball will wait to be illuminated here.
On chute main body 22, namely laser window 24 is equipped with in the upper end of nozzle 21, and this eyeglass is non-focusing lens, and Main Function has three:
1, through laser, allow laser penetration go down and melt the tin ball that is in nozzle 21 tip.
2, seal the working gas that blows, allow and blow ball gas and can not upwards overflow, and can only blow downwards, thus by the tin ball blowout nozzle 21 after fusing, until send on soldered workpiece, complete welding.
3, sealing detection air pressure, (referring to Fig. 2), allows the pressure sensor of gas (not drawing in figure) can measure air pressure change in tapered sleeve accurately, thus can judge whether there is tin ball in nozzle 21.Laser window 24 will be pushed down (referring to Fig. 2, Fig. 6) by eyeglass pressing plate 23.
The utility model also can have the warning of card ball, tin ball puts detection two controlling functions in place, is described below respectively:
Card ball is reported to the police
The utility model motor used is servomotor, when motor 15 normally rotates together with annex such as rotor 20 grade, the electric current that motor driver exports will be a certain steady state value, when meet accident card ball time, to high instantaneous current be there is in electric current, this will be arrived by systems scan, so system can think that card ball phenomenon appears in mechanism, therefore, operating personnel can be notified with the form of reporting to the police, need human intervention, remove card ball fault.
Tin ball puts in place detection
Because the specification of tin ball is too tiny, detecting in nozzle 21 whether have tin ball, in the utility model, is utilize the change of the tapered sleeve internal gas pressure detecting chute main body 22 to realize.
