According to above-mentioned technical characteristics, the laser welding main body is integrally formed and structure by laser and CCD camera
Into.
According to above-mentioned technical characteristics, the laser air-supply arrangement connector is that by up big and down small, inside is hollow
Conically shaped is constituted.
Advantageous effects of the present utility model：Because described light supply apparatus bottom is provided with for increasing the preheating of hot blast
Device；The preheating device includes the laser air-supply arrangement connector being directly connected with light supply apparatus, is arranged at laser air-supply arrangement
Hot blast connection tooth pipe on connector, the hot blast delivery tube of tooth pipe connection is connected with the hot blast, the hot blast delivery tube is arranged at another
The hot blast control box of one end, is arranged at the tray for work pieces of laser air-supply arrangement connector bottom, and be connected with hot blast control box
Hot blast exhaust apparatus.In welding process, because the hot blast that preheating device discharges is heated to pad and tin cream in advance, Ke Yi great
Amount is reduced in laser beam welding, and because of the factor that laser heat is concentrated, the moment of thermal weld is directly connected to from cold welding in tin cream, and
Cause the tin sweat(ing) grain number that the tin sweat(ing) in tin cream is splashed to around pad, it is to avoid cause short circuit phenomenon because splashing tin sweat(ing) is excessive.
While preheating device release hot blast is heated to pad and tin cream in advance, the flux activity in tin cream can be made, because slow
Slow preheating so that scaling powder uniformly melts so that remove bond pad surface oxide very well in welding process, reduces welded material
The tension force on matter surface, is conducive in welding process scolding tin to fill up pad uniform, smooth flow, reduce scaling powder residue in by
Welding workpiece surface, so as to improve welding quality.Again it is heated evenly due to soldering paste, it is to avoid soldering paste is produced greatly in welding process
Measure stomata.
To have further understanding to the purpose of this utility model, construction feature and its function, hereby coordinate accompanying drawing specifically
It is bright as follows：
【Brief description of the drawings】
