VVT bolt is an important part of automotive engine VVT, vvt bolt assembly line is fully automatic, the machine is designed to perform the automatic assembly, inspection, laser marking and data recording. The machine is made up of 7 processes, including spring base press-fitting, valve sleeve assembly, spring and valve core assembly, steel ball and circlip feeding, laser marking, bolt body thread checking and trace-ability system. Conveyor line and turntable transfer the parts to proper position, the manipulator takes the part for assembly, the HMI and PLC control system perform parameter correction and data recording for assembly process.

Machine characteristics:

1、weigh the product and protect the product well

2、Press-fitting force of spring base is 2000-3000N

3、After valve sleeve mounting, perform check valve open pressure and leakage test

4、Laser marking at designed area

5、Spray anti-rust oil(nebulization)

6、Full set trace-ability system

6、Password setting: HMI can set password to avoid Improper operation of equipment to damage the machine or hurt people.
