1.Introduction

Automatic color pen assembly machine is designed for automatic assembling watercolor pen, pen and other types of pen , with reverse, pen mouth,ink feed, copper head, fiber head, big hat, hat and  complete assembly process function.

2.Process requirements

Each vibration table sends components, the spindle drives each axis to move forward , through the spindle encoder to locate the assembly process action of different interval.Which could detect defective product, and automatic nesting for defective products.

3.The program

The control system uses a WECON LEVI-700LK HMI and an LX3V-2416MT4H PLC.

The main program functions are as follows: The PLC communicates with the inverter to control the motor speed. The spindle encoder provides positioning for the angular work interval. A high-speed counter (C252, with Z-phase) and the E-cam instruction are used to achieve action distribution.

4.The introduction of project 

HMI program: The screens primarily display the action intervals for each process step, the status of equipment, and key parameters.

PLC program: Inverter communication and filter setting

E-cam program

5.The summary of program

1, The system depends on the encoder interval positioning, which mainly relies on ABSD instructions. The operation of these instructions is a multi-segment comparison, which achieves E-cam control. The form, the counter, etc. are set in absolute manner.

2, Additional offset count, residual tracking program, making the system control program more reliable.
