In order to prolong the service life of reflow soldering, ensure the stable production of SMT, improve the output and ensure the product quality, every part of reflow soldering needs to be maintained very carefully.

①Track parallelism:

Measure the distance with vernier caliper. Adjustment method: take the width of the inlet as the reference point.

If the outlet is wide or narrow, using the fixed pliers and 19mm open-ended wrench to separate and loosen the chain and the rear end rotating gear bar of the track, and then turning the front and rear end transmission gear bar by hand to adjust to the same distance as the front and middle end.

②Track moving device:

If the track moving device fails to slide smoothly, it is necessary to manually adjust the track width to the limit and walk back and forth in the temperature range, and observe whether the track width is affected by the main force. If it is too tight, loosen the mobile device.

③Front and rear iron and steel plates of the fixed side of the track:

In addition to checking whether the iron and steel plates are offset with a level gauge, it is also necessary to check whether the fixing screws of the track are loose with a hexagon wrench. Ensure that the position of steel plate before and after the fixed edge of the track is stable and correct.

④Gear chains of track width adjustment drive motor:

It is necessary to check whether the gears and chains rotate normally, and the fixing screws of the axle center cannot be loosened, and keep their surfaces clean at all times, and then lubricate the gears and chains with lubricating oil.

⑤To adjust the width of the transmission rod:

The transmission rod needs to rotate normally, without dirt, deviation, bending or deformation. The rod surface must be kept clean and lubricated.

⑥Front end and middle fixed gear bar and gear:

They must be engaged normally, and there shall be no dirt, deviation, bending and other deformation.

⑦Middle fixed gear bar assembly:

It must move synchronously with the transmission motor, and travel smoothly. Remember to use a hex wrench to tighten the screws before checking the engagement.
