This assembly line adopts accumulative speed chain, and sets several automatic assembly stations, including automatic tightening station, air tightness testing station, automatic turning station, automatic marking and labeling station, automatic loading and unloading station, etc. The product assembly adopts one-piece flow method, which greatly reduces the labor intensity of operators and saves cost and improves production efficiency. The assembly of products adopts one piece flow method, which greatly reduces the labor intensity of operators, saves cost and improves production efficiency.

The pallet adopts four-guide cylinder to jack up and accurately position, and the pallet in place adopts Japan SMC blocking cylinder and with the front end blocking and stopping anti-return mechanism to determine the stopping position. Line sensor adopts Germany SICK or Japan OMRON and other imported brands, stable and reliable.

Adopting Japan Mitsubishi Q series PLC as the main control element, together with Taiwan Advantech industrial control computer for software preparation, it can be used for tightening and pressure and other data collection and subsequent tracing. The position of the electric cylinder can be set on the upper computer, and the electric cylinder adopts Japan SMC brand, which is directly sent from Japan to China, with reliable quality and durability.

The pallet is made of aluminum monolithic casting to ensure rigidity, durable and not deformed. The pallet elevator adopts Japan SMC rodless cylinder, which is beautiful and reliable.

Horizontal automatic tightening station, using SMC electric cylinder driven by South Korea Shitai tightening machine, the position of the automatic setting and automatic walking, to prevent leakage of screwing bolts, to ensure the tightening accuracy.

Longitudinal automatic tightening station, using SMC electric cylinder driven by South Korea Seetai tightening machine, the position of the automatic setting and automatic walking, to prevent leakage of screwing bolts, to ensure the tightening accuracy.

Automatic overturning station, automatic positioning after the arrival of the product driven by the pallet. The products are automatically rotated after being lifted up by the jacking cylinder, and the whole product rotation angle can be set so as to facilitate the assembly at a farther place.
