SMT classification
SMT machine manufacturers are many, so the classification is also a lot. As follows: by speed, medium speed SMT machine, high speed SMT machine, ultra high speed SMT machine. Divided by function: special machine and multi-function machine. According to the way points, group take group stick, group take sub stick and sub take sub stick. According to automation, automatic mounter machine (most laminating machine is this kind) and manual mounter machine.
Application of SMT
With its incomparable advantages, surface mount technology quickly replaces the traditional through-hole mount technology and enters the field of consumption and information products. Today, PCBA production of various lighting fixtures, portable and popular notebook computers, mobile phones, household appliances and other production are beneficial to this.
The role of the SMT machine
- SMT machine cylinder
The cylinder is usually used in combination with the solenoid valve to lift and stop. In the structure of SMT machine, cylinder is widely used.
The cylinder of the mounter will wear and enter dust during use. It should be checked regularly. Once any problem is found, it should be handled immediately. Unless the cylinder expands flexibly or fails to reach the specified position due to unclean compressed air, it will be cleaned immediately.
- SMT machine filter
The filter of the laminator plays the role of compressing and filtering pressure during installation to ensure the cleanness of air shrinkage gas. If there is dirt on the filter and the filtering effect is not good, it will affect the suction of the suction nozzle and directly affect the lamination effect.
- the patch machine reflector cap and reflector plate
The reflector plate is used to test the electrode size and nozzle number of components. When poor identification occurs during the patch, the reflector plate and reflector cap should be inspected or replaced.
- Mounting machine bearings
Bearings on the patch machine play two roles
First, limit, bearing limit refers to the fixed shaft can only achieve transformation, but can not carry out axial and radial movement:
Three, support, support refers to bear the radial load of the shaft. Bearings are divided into rolling axial bearings, ball bearings and thrust bearings according to their functions. Bearing is a standard part widely used in the structure of the laminating machine. It requires smooth operation. If it runs for a long time, there will be wear and tear. For example, the joint bearings and rolling bearings used in the patch machine.
