Summary of the invention:
The objective of the invention is at the deficiencies in the prior art, a kind of laser micro-welding process of network filter is provided, this technology can reduce production costs, and enhances productivity, and guarantees product quality, satisfies the unleaded environmental requirement of product.
For achieving the above object, the present invention is achieved by the following technical solutions: laser micro-welding process of network filter, and it may further comprise the steps:
The first step, the punching press copper sheet is pin and the pin frame that links together with the copper sheet punch forming, and pin comprises pin root and pin tip, and described pin tip is the clip slot shape;
Second step, the bending pin;
The 3rd step was wound into the lead-in wire that twines the ring magnetic coil on the pin, formed to-be-welded pieces;
In the 4th step, to-be-welded pieces is placed into the laser works platform;
In the 5th step, laser instrument emission micro laser beam is a laser point with pin tip clip slot, and to-be-welded pieces is carried out the laser scanning welding, and the lead-in wire on pin melts the back and is wrapped in pin links to each other;
In the 6th step, cut pin and be processed into semi-finished product.
In the described first step, described copper sheet is the phosphor bronze sheet.
In described second step, bending pins becomes 87 ° ± 10 ° shapes, is asymmetric staggering between pin.
In described the 3rd step, the canoe that described lead-in wire is wound on the pin is, lead-in wire is around pin root 2～3 circles, again 3～4 circles and stick into clip slot around the pin tip.
In described the 4th step, the described process that to-be-welded pieces is placed into the laser works platform comprises, the clamping to-be-welded pieces transmits to-be-welded pieces to workbench, accurately locatees to-be-welded pieces.
In described the 5th step, the condition of work of laser instrument is, peak power output is 300W, and rated welding current is 63A～315A, and laser beam wavelength is 1.06 μ m, and the minimum light spot diameter is 0.4mm, and the speed of welding of laser instrument is 40～200 solder joints of per second.
Described the 6th step is used epoxy tree resin, with the semi-finished product injection mo(u)lding after cutting pin and being processed into semi-finished product.
Beneficial effect of the present invention: the present invention does not use any scolder, directly scan welding by laser beam, make the network filter after the welding unleaded, and the heat-affected zone of laser weld is little, therefore the present invention has and reduces production costs, enhance productivity, guarantee product quality, satisfy the advantage of the unleaded environmental requirement of product.
