Mounting machine failure analysis and troubleshooting

Whether the placement machine operate normal or not directly affects the placement quality and PCB manufacturing output. In order to run normally of machine, it is necessary to fully understand the structure and characteristics of the machine, to grasp the manifestations of the machine prone to various failures, the causes of failures, and the troubleshooting methods. Only by timely discovering the problem, finding out the cause, correcting and solving the problem in a timely manner, can the machine exert its proper placement efficiency.

1, common faults

Common errors include equipment aspect, as well as errors in picking up and posting errors. The main types of errors are the following.

A. The machine does not start:

B.The mounting head does not move

C.The PCB does not go forward after loading the board:

D.Pickup error:

E.Mounting error.

2, the main cause of failure

The main reasons for the failure are the transmission system, air path, nozzles, components, and placement procedures.

A. Transmission system-transmission system that drives the movement of PCB and placement head and corresponding sensors;

2 Air circuit--pipe, nozzle;

B.The nozzle aperture does not match the component;

C. The program setting is incorrect-the image is not well made or is not registered in the component library;

D. Irregular components-inconsistent with the image:

E. The component thickness and placement head height are incorrectly set.
