01Background

With the upgrade of the domestic automobile consumption market, besides traditional automobile manufacturers, many new car-building forces have developed in recent years. The four modernizations of the automobile have promoted industrial upgrading. New models and modified models release each year have become more frequent and product become diversified and customization has become a new competition point for various manufacturers. This also puts forward higher requirements and challenges for auto parts manufacturers.

02Pain points

In 2018, an automotive central control screen supplier was asked to complete the design and commissioning of an automated assembly production line for two automotive central control screens of a new energy vehicle within three months, while ensuring the car’s product shipments, consistency, and quality. The automobile factory investigated into some of the mainstream auto parts manufacturers at the time and found that most of the automated production lines used two modes: either manual production lines or xyz Cartesian coordinate robot production lines built with linear modules; therefore, users preferred to use the modules during the initial stage of the project. ELITE and the integrator analyzed the production process of the vehicle’s central control panel, and found that the project involved the process of screen component inspection, press-fitting, screw locking of the circuit board and shell, screen function test, and assembly of the back shell. The process is complicated and highly coupled; if the traditional module method is used, although the production process can be achieved, it can no longer properly meet the future production requirements, so we recommend the client to use robots as the core automation solution.
Integrators recognize the innovation of the robot solution and believe that advanced automated production concepts can bring a good demonstration effect to their end users. However, as a traditional manufacturing company, integrators still had some concerns: one was cost; the other was whether the production accuracy and cycle could meet the requirements; the third was whether it could meet the project cycle.

03Solution

ELITE and integrators have conducted targeted research and design taking customers’ processes and concerns into consideration, and have taken full advantage of ELITE’s complete product line- integrating collaborative robots, industrial six-axis robots, and four-axis SCARA robots. By combining the technical characteristics and advantages of different categories, we quickly submitted a collaborative, industrial and SCARA mixed line solution. The advantages of this solution are very obvious: the cooperative robot with upside-down installation is assigned to the tight-spaced loading station. The structure is compact and the human and the machine are working side by side; the SCARA robot will execute the barcode reading and assembly inspection of incoming materials and the screw tightening process because the robot only needs plane operation, and the tempo need is high. The high-speed industrial six-axis robot will move the material and assemble in different stations. 

04Results

ELITE’s excellent core technical capabilities and high component self-research rate make the cost of robot equipment economically controllable, and the product accuracy reaches the level of mainstream products in the industry, which can fully meet clients’ requirements. In addition, thanks to the optimized robot design, the entire solution has the characteristics of compact structure and easy maintenance. As a standard component, the robot simplifies the design of the mechanism. It has good interchangeability and can greatly reduce the risk of the entire solution as well as the risk of a downtime. The entire production line uses one collaborative robot, three SCARA robots, and three industrial six-axis robots. The same ELITE controllers and programming and operation methods are used. The adaptation to different products can be completed by writing different programs, which improves the efficiency of customer’s maintenance staff, and the flexibility of the production line is greatly enhanced. The project completed the design, deployment, commissioning, and launch of the project within three months as scheduled, and met the needs of the integrator for customer orders.

In this project, ELITE’s full range of robots are used. For different application scenarios, ELITE can provide clients with the most suitable products. The decade-long technology accumulation in control systems, and guaranteed self-sufficiency of core technologies and give ELITE a good advantage in the fierce market competition.
