Abstract

Developing to modular mechatronics system has been a need for complementary mechatronics learning system at Politeknik Manufaktur Astra. The system is a whole and integration in the conveyor belt system. We design a rotary gripper station that can be used for lifting work-object by gripping it with the vacuum. After work-object has been gripped, then shift it to the next station. In this paper, we design a rotary actuator as an actuator tool that can move by rotary until 1800. Based on the design results, calculation analysis, and testing this equipment, has been getting that the equipment specification as the same with the needs.

Abstract

Tingginya angka produksi perusahaan manufaktur membuat semua mesin harus mampu bekerja dengan baik. Mesin jig UUA Tack, line Underbody sering mengalami kerusakan pada sistem kontrolnya akibat error module sehingga line stop sering terjadi dan pada akhirnya tidak mampu menunjang angka produksi perusahaan. Untuk menanggulangi permasalahan tersebut maka dilakukanlah modifikasi dengan mengganti sistem kontrol menggunakan Programmable Logic Controller (PLC) dan membuat program (ladder diagram) yang disesuaikan dengan proses kerja pada mesin sehingga modifikasi ini diharapkan mampu mengurangi angka line stop pada mesin dan dapat menunjang produksi perusahaan.

Abstract

Penelitian ini dilakukan di sebuah perusahaan yang bergerak di bidang pengembangan industri otomotif. Testing & Durability Laboratory merupakan sub-departemen yang fokus pada pengembangan pengujian-pengujian di bidang komponen otomotif. Pengujian lithium battery jenis lithium-polymer (li-po) merupakan pengujian yang dilakukan untuk mengetahui berapa kapasitas lithium battery serta memonitor tegangan baterai dan arus charging-discharging pada baterai, dan untuk melakukan verifikasi antara rancangan kapasitas baterai dengan kapasitas baterai yang sudah dibuat. Divisi EDC menginstruksikan kepada penulis untuk membuat sebuah alat yang dinamakan Life Cycle Test. Alat Life Cycle Test dilengkapi dengan beberapa piranti yaitu sensor ACS untuk membaca arus ketika proses charging, sensor CSLA untuk membaca arus ketika proses discharging, dan voltage divider untuk membaca tegangan lithium battery. Dan juga SD card yang terdapat pada modul data logger yang digunakan untuk menyimpan data dari hasil pengujian. Pembuatan alat Life Cycle Test untuk men-charge dan men-discharge baterai secara otomatis dilakukan dengan menggunakan mikrokontroler arduino uno. Program arduino uno dibuat agar baterai dapat charge-discharge secara otomatis dan dapat menyimpan data (kapasitas baterai, arus charging discharging, dan tegangan baterai). Sehingga nilai kapasitas baterai dari hasil pengujian dapat diketahui yaitu sebesar 2341.5 mAH.

Abstract

In automotive manufacturing, accurate product marking is essential for traceability and safety. One interior component requires laser marking of the label "AIR BAG" and the attachment of a QR code. However, production data revealed recurring defects due to missing QR code labels or skipped marking processes, which were caused by the lack of a verification system. This study aims to design and implement an automated QR code verification system using a Raspberry Pi 4, a single-board computer (SBC) of this type. The novelty of this approach lies in its cost-effective integration of hardware and image processing software (OpenCV) to detect QR codes in real time. The system is designed to scan for a QR code before the laser marking process begins. If a QR code is detected, a signal is sent to the laser machine to proceed with marking. It ensures that each product is verified correctly and marked. The method involved prototyping, software development, hardware integration, and implementation on a real production line. Results showed a significant reduction in marking-related defects and an improvement in process reliability. This solution minimizes operator error, enhances production efficiency, and supports quality assurance. Future work will focus on integrating the system with PLC-based controls and exploring machine learning techniques to enhance detection accuracy and facilitate predictive maintenance.
