Application of Wecon hmi & plc in lock screw machine

Ⅰ Brief introduction

Automatic locking screw machine is also called automatic feed screw machines, automatic locking screw machine, industrial systems and tighten the screw lock pay robots, is a machine to replace the traditional manual screw down.Manual screw include pure hand tight and electric screwdriver or pneumatic screwdriver screw down , the latter by way of electric or pneumatic rotating power, instead of the frequent hand tighten the action, to some extent alleviate the work intensity of the lock screw, but due to manual screw placement, and on the screw head is still need to work takes up a lot of time and energy, so the overall efficiency is limited.

Ⅱ Operating principle

Automatically lock screw machine contains screw the whole unit, automatic screw conveyor unit and automatic tighten screw unit and test unit in the process of lock.

Screw automatic line unit will column loose screws lined up and a single output.The line units can separate by the vibration plate.Institutional implementation can also through the institution of swing arm screw to implement.Automatic screw conveying unit mainly to transfer the single screw to the before of screw unit.Automatic tighten the screw unit consists of rotation drive part and screw the import parts.Screw import way of common are blowing and adsorption.In general, blowing type due to continuous work, do not need to head back and forth movement, therefore, the overall efficiency is better than that of adsorption.But blowing type itself is limited by a screw shape and length to diameter ratio, not every kind of screw is suitable for blowing type.Detection unit detection problem including leakage locking screws, floating lock, card material, etc

Ⅲ Introduce the program

1.Operation screen: This picture mainly shows the current work of product Numbers, screw points, production, abnormal reset,etc

2.Manual opereation screen: In manual mode force the output of each cylinder,forward and inversion of each servo motor.

3.Coordinates formula:This screen save five kinds of products coordinate values of each working point.Convenient to call.

4.Coordinates setting: This screen mainly provided to the customers to set the coordinates of each point,Customers control motor to the each working point move by manual,and then execute each coordinate input, you can record the coordinates of each working points.

5.Main point of program:

(1)Four servo back to the origin.

(2)Location of four servo.

(3)Allocation and optimization of formula screen address.
