Structural Features

1. Frame structure :The main structure is whole welded with square tube, solid and reliable.

2. Transmission system:The mode of the component is transverse entry, that is, three surface canvas conveyor belt feeding, the transmission motor is controlled by frequency conversion.

3. Soldering system:The soldering system is triad structure, with each soldering head three axis direction independent movement of X, Y, R, to ensure the best soldering position.

4. Vision system:CCD high-definition industrial camera with 5 to 10 million pixels is optional to achieve the precise positioning of the junction box.

 5.Automatic tin loading system: With the material shortage alarm device, can realize the quick replacement of tin wire, compatible with tin roll weight 1-3kg

6.Control system :The control system can interactively upload device information with MES system.
