The car central control screen is getting bigger and bigger, who is doing it

background

With the trend of intelligent vehicle machine system, in order to better visual interaction experience and content loading, the screen size has also undergone great changes, and the on-board central control screen is being popularized to more and more models, and the large screen has better scalability, can display more content, and has stronger customization capabilities. Located in East China, this automotive supplier has set foot in the research of large-screen car machine solutions earlier, focusing on interactive experience and fully considering user needs - it has strong advantages in stability, safety, reliability and other aspects. With the rise in the demand for customization, manufacturers need to have more flexibility on the supply side to meet the rapid changeover and changes of multi-variety production lines, so they have been looking for automation solutions that can help existing production lines improve production efficiency and have flexibility.

pain point

Since the development of collaborative robot technology, one of the most widely used scenarios is the auto parts industry, including Continental Automotive Electronics, Valeo, BMW, Audi, SAIC Volkswagen, Nissan, etc., and other major vehicle and Tier One manufacturers have introduced collaborative robots in the back-end process for handling, assembly, screw locking, testing, gluing and other applications. Unlike traditional industrial robots, which need to be equipped with safety fences, collaborative robots can realize the sharing of man-machine operating space, and the rich interfaces and easy-to-use programming experience make this production tool flexible, lightweight, safe and easy to program in the process of use. Therefore, more and more factories are learning from similar application scenarios of collaborative robots and incorporating them into the single-station transformation of existing production lines.

In this case, the user wants to try the cobot at the inspection station, and the central control screen stays on the inspection station for 75 seconds, without any room for error. Manual needs to carry out key and touch screen detection on each product, and the product can be transferred to the next process only if the product is qualified. "At this stage, we have been using manual work to perform this task," said the engineering director, "As long as it is manual operation, there will inevitably be errors and omissions, so we have always wanted to replace manual labor with automation solutions to improve the efficiency and accuracy of product inspection." ”

The user chose to arrange the Elite EC63 (3kg load) cobot in the touch screen quality inspection post, and when the EC63 stylus clicked on the touch panel, if there was no quality problem with the material, it would flow out smoothly. If an anomaly is detected, "NG" will be displayed on the display, and the signal light will be lit with the alarm sound of the siren, so that the operator can immediately notice the anomaly and deal with it in time.

Two EC63 desktop cobots are used at the end inspection station, with the robot on the left performing key detection and the robot on the right performing touch detection on the touch screen. Collaborative robots are especially suitable for automation transformation in small spaces, and meet the requirements of curved or double-sided screen detection.

The head of the engineering department said: "In order to ensure the personal safety of our employees, we have conducted a risk assessment in accordance with the company's safety standards. For example, when EC63 was first introduced, we made some adjustments to ensure security. Because the working accuracy and stability of cobots are higher than those of humans, they can still meet the requirements of the production line and the quality of the inspection work has also been improved. ”

From the delivery of the robot, to the overall design, installation and testing of the system, and the on-line operation, the whole cycle took about one and a half months. Connecting the robot to external devices such as PLCs and PCs is a difficult step. According to the customer, "After about two weeks of repeated testing, we set up our own independent system. "It is worth mentioning that Elite worked with the customer to improve the design of the fixture, and after repeated fine-tuning of the fixture, the gripper touch is more adaptable and can support the various touch modes required for inspection.

The supervisor in charge of the inspection station said confidently about the introduction of the cobot, "Employees are prone to errors when using the touchscreen system, but I am satisfied that the cobot can do the job accurately." Once the robot is activated, the inspection task can be carried out by the robot independently, so the productivity is also much higher. In the event of an abnormal outage, the system will send an alarm and the person in charge of production technology will come to check on it, so we can rest assured that production will not be interrupted. ”

In fact, the user saved about 1.5 man-laborers by using the cobot, and the cost was paid for itself within 18 months. As a result, the company plans to deploy more cobots in other production lines. "The assembly process has always been a labor-intensive process, and it is not excluded that we will try to replace people with robots in these positions in the future, after all, flexible automation is a major trend in the future." For the future, not only Elite, but also the confidence and experience accumulated by users in practice will bring more imagination.
