This series of equipment is the welding machine with double Y-axis and double workbenches. By feeding product at the pre-process and taking product at the post-process, its production efficiency is twice as high as that of the single Y-axis welding machine. It adopts the special assembly process of synchronous belt and motor to completely solve the tension and loosening problems of the synchronous belt used previously. It also can adopt the precision screw rod to control and is suitable for the product with high welding requirements. It is widely used in various electronic fields such as digital products, communication electronics, household appliances, automotive electronics, electrical products, consumer electronics, power supplies, tools , toys and lamps.
