Design control system of auto air remaining machine based on programmable logic controller in the automotive manufacturing industry

This research was conducted in one of automotive manufacturing industry of shock absorber. Air remaining is the process of preparing Shock Absorber to achieve ideal conditions i.e. ready to test the quality of its damping power. The trick is to remove the gas fluid contained in the cylinder so that the fluid remaining in the cylinder is just the oil fluid. If there is still a gas fluid left in the cylinder at the moment of the damping test, the Shock Absorber will experience momentary loss of power and this will greatly affect the quality of the Shock Absorber. The high frequency of repetition in the process of testing the quality of the damping power Shock Absorber on the Damping Force Tester machine due to not ideally Shock Absorber condition. This condition is one of them caused by the error of method in previous process that is air remaining process. Based on the above problems, then we research and design of new methods of operation of auto air remaining machine and design the control system. The method used is to utilize the gravity and the density of the two types of fluid, namely oil and gas to optimize the elimination process in Auto Air Remaining machine. The gas fluid can be perfectly eliminated. Control system design using Programmable Logic Controller (PLC). The Input and Output of PLC has used are 19 of inputs and 19 outputs. This method ensures the removal of the remaining air process.

This research was conducted in automotive manufacturing industry company in Indonesia. There is one Key Performance Index that needs to be fixed, that is the process mounting actuator bracket. The type of trouble that can occur on the actuator bracket is on the quality of the mounted bracket. The bracket mounting process is carried out using three bolts on each side which must be mounted with a predetermined torque value of 5.4 Nm. Manually process can cause bolt on one side or more. Based on data from the Quality Assurance network, the process diagnostic table or tightening has shown less optimal installation process of actuator bracket on actuator brake in Jundate Trimming. The absence of line stop detection on a jig can cause a torque process error on one or more bolts. We modify the mechanical design of the pokayoke system. While the jig design is not modified there is only the addition of clamp systems that serves to determine the position of the work piece, proximity sensor as a detector work piece, and push button as a button to distinguish the work piece between ABS work piece and VSC on jig. This pokayoke system is based on Programmable Logic Controller control. This pokayoke system design prevents the occurrence of damaged bolts on screw threads when mounting an imperfect actuator bracket.
