Why You Need Annual Maintenance for SMT Equipment?

14 Jun 2019

The technical innovation of any piece of equipment will gradually deteriorate with the increase of the service life, and the cooperation of various parts will inevitably produce different degrees of wear and looseness. The replacement of the internal lubricating oil of the machine is not complete, the moisture and oil contained in the gas path, etc., and the dust caused by improper environmental control may cause a large amount of dust and scale, gas path, solenoid valve, vacuum generating device, etc. accumulated inside the machine. To Learn more maintenance for SMT Equipment, please visit the leading electronics manufacturing expo in China NEPCON ASIA. Grease and moisture, excessive dust on the circuit and board, if it is not timely targeted protection and maintenance, it will affect the normal operation of the machine, and may cause excessive wear of some components and even lead to serious accidents. Therefore, it is necessary to carry out regular maintenance of machinery and equipment purchased at electronics manufacturing expos in accordance with scientific maintenance methods and technical specifications, so that all parts of the machine can always work well and reach full life.

Annual maintenance effect

Clean and remove the dust and scale on the surface of the machine and circuit board, so as to avoid the heat dissipation inside the machine due to dust and scale, causing the electrical parts to overheat and burn out;

Disassemble and clean the internal gas path, solenoid valve, vacuum generating device, cylinder, etc.; if the grease in the gas path can not be cleaned in time, it will block the gas path, resulting in poor gas path, resulting in high throwing; serious situation Under the corrosion of solenoid valves, vacuum generating devices, cylinders and other internal seals and components, resulting in damage to components, finally affecting the normal production of the machine;

Clean and lubricate the moving parts of the machine. Long-term operation of the machine, due to improper environmental control, there will be very dust on the moving parts (such as: screw, guide rails, sliders, drive belts, motor couplings, etc.). You can meet more suppliers at electronics manufacturing expos. If the maintenance and cleaning of the machine part is not timely and professional, the machine will run under overload for a long time, which will affect the life of the machine;

The machine has passed the warranty period and has been running for a long time. It is impossible to carry out comprehensive professional maintenance on the machine. Some parts of the machine probably purchaesd at electronics manufacturing expos have hidden dangers (such as: wear of the machine line, wear of the cable frame, looseness of the motor and screw fixing screws, etc.) Some mechanical parts do not work well, parameter settings are wrong, etc.), the machine is heavily maintained, timely inspection and discovery of hidden dangers inside the machine and solve, thus reducing the frequency of machine failures and improving production efficiency;

After the machine has been running for a long time, the relevant parts of the machine are worn, displaced, aged, etc. The most primitive parameters of the machine can no longer adapt to the current situation of the machine. The mounting accuracy of the machine has been seriously affected. Therefore, the machinea must be corrected regularly. Make the machine produce under the highest precision and improve the quality of the product;

Annual maintenance of the machine can effectively reduce the throwing rate, reduce the number of alarms, improve machine production efficiency, and improve production quality.
