The automatic welding machine improves the welding work by four to six times, and the automatic welding machine changes the welding machine cooling practice that the welding machine can only rely on natural cooling or PCB outlet, making the reflow process curve more perfect, avoiding problems such as surface mount equipment damage and welding deformation. With the popularity of automatic soldering machines, many workers are not familiar with installation and maintenance, there are different problems, such as fixture errors, what is the cause of this problem? How to solve it?
1, automatic soldering machine base positioning error
In the past, it was not possible to use two positioning tools, which, if forced, would result in an error in the Y-axis motion; Now, you're going to use the locator pin. Although this problem has been solved, but the positioning of the positioning pin has a new problem, so the positioning is not accurate. Every time you put the mold on the chassis, there's a positioning error.
2. Installation error
Since the iron core and FPCB need to be installed manually, whether the FPCB is installed in the horizontal plane and whether the vertical nickel plate is completely inserted into the hole of the welding plate, the degree of installation is directly related to the quality of the welding.
This is a big problem affecting welding quality at present. Due to the influence of machine tool accuracy and manual technology in smelting tool manufacturing, the size of each smelting tool can not be completely consistent, combined fixture tolerances, so the same fixture placed in different channels will produce errors, it turns out that this is a welding quality error.
3. Post-maintenance is difficult
Due to the need for high-precision welding, after all, errors disappear, new welding errors will be generated during the use of jigs, such as manual loading errors, tilt errors of nickel plate holes, smelting tools in the process of use, new errors caused by maintenance, scrubbing, grinding, etc.
The solder joints should not be too full when the soldering machine is working, and too large solder joints and adjacent solder joints are easy to break. And when the soldering machine is working, do not save too much tin, which often leads to virtual welding (where to work if you are not full). The correct use of the solder joint of the automatic soldering machine is in the middle of three or four points, the solder joint should be a small semicircle and the component foot, unsaturated tin, so that the solder joint contact is good, and the solder spot is clean and safe.
If the AC contactor is not turned off when the soldering machine is in use, that is, the power grid voltage is too low, the user should quickly solve the power supply problem, and can be used after the power supply is normal. However, if the main parts of the newly purchased automatic soldering machine have quality problems, you can directly replace the new automatic soldering machine or replace the main parts. Automatic soldering machine warranty one year, long-term maintenance service. In this case, notify the factory directly and the service is in place from three to seven days outside.
Soldering machine should use adjustable temperature soldering iron; When the iron head is not in use, Z should put a certain amount of tin on the iron mouth. Do not clean the iron holes in the sponge. Store on metal shelves. Sponges need to moisturize, so they stay wet all day.
I really don't know. The original automatic soldering machine operation also has a lot of "do not pay attention", in fact, as long as we do a good job of the daily maintenance of soldering, not only can save labor costs, but also improve work efficiency, become the top "robot factory" in the new century.
