Abstract
The invention discloses a method for welding a tongue piece of an automobile back windshield. The method not only requires low-cost equipments and has convenient application process but also overcomes the quality defects of the prior art. The method has following steps of: (1) making column-shaped soldering tin to be flat by adopting a knocking method or a pressing method, and cutting the flat soldering tin into soldering tin pieces matched with the size of the tongue piece for standby; (2) opening a self-air temperature-adjusting plastic welding gun for pre-heating and standby; (3) using a glass-fiber bar for wiping silver paste at the positions to be welded on the windshield surface so as to remove an oxide layer; (4) placing the soldering tin pieces on the welding position and putting the tongue piece on the position, and then rapidly adopting the welding gun to blow and heat the soldering tin pieces so as to complete the welding after melting the soldering tin; and (5) placing the windshield on a special frame for cooling after completing welding. The method is simple and practical and can be popularized easily.
Description
Technical field
The present invention relates to a kind of method for welding tongue piece of automobile back windshield.
Background technology
Known, automobile back windshield needs the printed silver slurry, sinter heater wire (being used for defrosting after the energising) at the cold district vehicle glass, general silver slurry pattern as shown in Figure 1, wherein 1 represents automobile back windshield, the silver-colored slurry of 2 expressions, tongue piece 3 (joint that connects silver slurry and lead) is welded on the silver slurry bus 21.
At present, the maturation method of automobile backstop tongue piece welding is to adopt special-purpose tongue piece bonding machine welding.Because professional more intense, the tongue piece bonding machine of this special use has only external production at present, price is about 300,000 RMB.This kind equipment is not only relatively more expensive, and there is obvious defects in using: the one, this kind bonding machine adopts the spot welding mode, promptly withstand the heating of switching on of tongue piece two ends by two root bead pins, glass only has two minimum points to be heated like this, and temperature reaches about 500 ℃, the part of glass makes stress equilibrium destroyed because of expanding with heat and contract with cold fast like this, and therefore the strength of glass after the welding descends rapidly, and the self-destruction probability also can increase; The 2nd, this welding manner is owing to be to advance tin automatically, and solder stick is handled, and is cylindrical shape, and the contact area with tongue piece, glass is little like this, causes that easily rosin joint, scolding tin do not melt, the stability of influence welding; The 3rd, silver slurry surface was exposed to before welding and can be subjected to the oxidation of part degree in the air, and weld force can be affected like this, and the technology that present welding manner is not handled silver slurry surface.
Summary of the invention
Technical problem to be solved by this invention provides a kind of new method for welding tongue piece of automobile back windshield, and not only the equipment needed thereby price is low, easy to use to use this method, and can overcome the mass defect of existing mode.
The technical solution adopted in the present invention is: the present invention follows these steps to carry out:
(1) adopt the method for striking or pressing to make flat in cylindrical shape scolding tin earlier, and be cut into the solder plate that mates with the tongue piece size, stand-by;
(2) open from wind temperature adjustment plastic welding gun and carry out preheating, stand-by;
(3) need the silver slurry of welding position to carry out wiping with Fiber glass rod to glass surface, remove oxide layer;
(4) solder plate is placed on the welding position, puts tongue piece, then rapidly with welding gun to its heating of drying, after the melts soldering tin welding finish;
(5) the good back of welding glass is placed on the special-purpose frame and cools off.
The invention has the beneficial effects as follows: at first, the present invention uses from wind temperature adjustment plastic welding gun and replaces the tongue piece bonding machine, this kind welding gun price only is about 150 yuan, the more important thing is, it does not adopt the mode of local spot welding to weld fully, but pass through towards tongue piece, scolding tin and silver slurry position blowing hot-air, make melts soldering tin, this mode biggest advantage has overcome local heating exactly, tongue piece in the blowing process, scolding tin, silver slurry and glass heat simultaneously, heating surface (area) (HS surpasses 10 times of spot welding, and because of heating is by the blowing mode, be heated and non-heat affected zone does not have obvious limit on glass, farthest having avoided expanding with heat and contract with cold fast because of the part makes stress equilibrium destroy the defective that produces;
Secondly, scolding tin to cylindrical shape before welding carries out preliminary treatment, the method of it being struck or pressing is made flat, be cut into solder plate then with tongue piece size coupling, big during welding owing to contact area, add that heating surface area is big, and temperature is no more than 200 ℃ of scolding tin and just can melts rapidly, so firm welding and not only to almost not influence of strength of glass;
Once more, the silver slurry to position to be welded on glass before welding carries out preliminary treatment, adopts Fiber glass rod that it is carried out wiping, removes oxide layer, and weld force can be significantly increased.
To sum up, use the method for the invention, cheap, the easy operating of equipment needed thereby.Can also produce than the better product of bonding machine welding quality simultaneously.

The specific embodiment
Method for welding tongue piece of automobile back windshield of the present invention is characterized in that, it follows these steps to carry out:
(1) adopt the method for striking or pressing to make flat in cylindrical shape scolding tin earlier, and be cut into the solder plate that mates with the tongue piece size, stand-by;
(2) open from wind temperature adjustment plastic welding gun and carry out preheating, stand-by;
(3) need the silver slurry of welding position to carry out wiping with Fiber glass rod to glass surface, remove oxide layer;
(4) solder plate is placed on the welding position, puts tongue piece, then rapidly with welding gun to its heating of drying, after the melts soldering tin welding finish;
(5) the good back of welding glass is placed on the special-purpose frame and cools off.
The welding method of the tongue piece of automobile back windshield of the present invention is simple and practical, the use equipment price is cheap, promotes easily.
