The automation of welding processes is an important technology that enhances productivity and quality in the manufacturing industry. In particular, the automation of spot welding and arc welding has become a significant challenge in many manufacturing sites. This article will provide a detailed explanation of the key points when automating these welding techniques with robots. *For more detailed content of the blog, please refer to the related links.

Due to the labor shortage in logistics, it has become important to improve the efficiency of product shipping preparations and loading and unloading. In this article, we will compare and explain two representative methods (collaborative robots and industrial robots) for those considering automation. Collaborative robots are robots that can work safely alongside humans. They have the advantage of not requiring safety barriers, making them easy to implement even in space-constrained environments. *You can view the detailed content of the blog through the related links.

The coating process plays an important role in the manufacturing industry. By automating the coating process, many benefits can be achieved, such as improved production efficiency, uniform quality, and ensured safety. This article introduces specific points and examples regarding the automation of the coating process. There are several challenges associated with manual coating processes. - Variability in quality: Manual work requires measures to address quality variability due to the skill of the worker. - Low efficiency: Manual work is time-consuming and tends to result in low production efficiency. - Safety issues: Solvents and paints are often harmful to the human body, which can threaten the safety of workers. *For more detailed information, please refer to the related links.

We would like to introduce the demonstration of the "collaborative robot." A demo was conducted to operate the robot using an external device. The UR5e was controlled with a game console controller. In the demo of contact position correction using a force sensor, position correction was achieved without using a vision sensor. Additionally, the 3D-shaped workpieces were compatible with G-code. This made it suitable for teaching applications such as coating, sealing, deburring, and welding. A live demonstration of the vision system combined with the collaborative robot was also conducted. Object recognition using a 2.5D camera, an introduction to our vibrating parts feeder, and position correction using landmarks were performed. [Demo Content] ■ Demo 1: Operating the robot with an external device ■ Demo 2: Contact position correction using a force sensor ■ Demo 3: Compatibility with 3D-shaped workpieces ■ Demo 4: Vision system + collaborative robot *For more details, please feel free to contact us.

This device is a semi-custom dual-sided simultaneous protective film application system that accommodates various types of sheet materials. It was developed in response to requests from a punching metal manufacturer and has been implemented in multiple construction material manufacturers (steel and resin-based). It can be retrofitted into existing conveyor lines as part of the laser processing → inspection → film application process. By applying film to both sides simultaneously, it achieves processing times that are less than half of the traditional single-sided application done twice. Changing the width and length of materials can be completed without tools, and it flexibly accommodates design integration with previous processes (inspection) and subsequent processes (palletizing). By eliminating the risks of uneven manual application and scratches, it significantly reduces the burden on operators, contributing to improved line operating rates and stable quality maintenance. *For more details, please feel free to contact us.

This is a protective film application unit designed with partial implementation in mind to reduce the burden of introducing equipment for construction material factories. It accommodates 2m x 3m sheets and can be integrated behind existing inspection lines or laser processing machines, completing the automation of the application process. Thanks to its semi-custom specifications, it fits into existing layouts with minimal modifications. After implementation, it can shorten application time compared to manual application, potentially reducing labor costs by several million yen annually. We propose an optimal investment plan for medium-sized factories that prioritize cost-effectiveness in equipment expenses. *For more details, please feel free to contact us.*

This is a modular unit that allows outsourcing of only the protective film application process for line builders and SIers. It adopts a double-sided simultaneous application structure compatible with 2m x 3m sheets, avoiding the risks associated with developing from scratch in-house. Since it can be easily integrated into the latter part of existing transport lines, it also reduces the risk of delays in the overall equipment delivery schedule. This enables us to address projects that were previously lost due to insufficient equipment capacity, while shortening in-house development time and increasing deployment speed. *For more details, please feel free to contact us.

This device is a fully automated welding distortion correction system developed for construction machinery parts manufacturers. It automates the entire process from bulk picking for parts supply, robot welding, cooling transport, distortion correction, to palletizing. Compared to traditional manual distortion correction, it reduces the work time per process, achieving both uniform quality of heavy machinery parts and labor savings simultaneously. It can be optimized for each company's line configuration with full-order and semi-order support. We can flexibly accommodate requests for automation of only certain processes or phased implementation. *For more details, please feel free to contact us.
