In the wave soldering, why the chain will shake it, our experimental test found that the root cause is friction, then how to accurately identify the cause of the problem, we summarize the following points, but also lists the treatment, I hope each operation Master this skill.

Wave soldering chain jitter reasons:

1, the chain is too tight;

2, poor lubrication;

3, the Department of Transport synchronization chain tensioning device is OK;

4, chain claws encountered other things;

5, the guide has a bell mouth phenomenon;

6, entrance connection adjustment unreasonable;

7, the transmission gear on the machine loose.

Wave soldering chain jitter processing methods:

1, adjust the entrance of the connection tensioning device, adjust to the appropriate location;

2, add appropriate amount of high temperature lubricating oil to the chain once in January;

3, adjust the transport Department of tensioning device, must be tightened, and to ensure that in the same straight line;

4, check all the chain claws have not encountered other things, especially the claw claw box and the chain claw in the corner of the place have not encountered, replace the serious deformation of the claws;

5, there is no PCB track on the track, the chain is not jitter, and the board will shake the situation, then the guide has a trumpet phenomenon, you must first solve the problem of rail trumpet, as follows:

a, as the case may be, remove one or two gears at the screw;

b, choose a standard PCB board, placed on the track, and then turn the screw, the track before, during and after the width of the same tune;

c, reset all gear installed.

6, A, the entrance of the two rails connected with the main track of the two chains are not in the same line, will increase the tension, resulting in jitter, adjust the method: Take two standard test board, one on the connection, one on The main guide rail chain, adjust the connection, so that two in the same line, convergence in the two pieces of the same space;

B, connected to the chain too tight jitter caused, can be adjusted;

C, connecting the chain of small sprocket bearing damage or small sprocket within the gasket caused jitter, replacement and installation can solve the problem.

7, a comprehensive inspection of the entrance, exit of the transmission gear of the machine is loose, tighten all the machine can be.
