As the core support component of the power battery of new energy vehicles, the battery tray is the "key line of defense" to resist the impact of the external environment, and the slightest sloppiness may affect the quality and performance of the finished battery, and even cause irreparable extreme accidents. Therefore, in the actual production process, the use of intelligent, automated, and flexible technical means to inspect the battery tray has basically become the mainstream method.
In this case, the end customer is located in Guangdong, mainly engaged in the production and sales of auto parts, and with the rapid development of the new energy vehicle industry, the customer received a large number of orders for the production of battery trays, most of which are "small batches, multiple varieties" and other needs.
Han's Robotics Elfin cobot is equipped with 3D industrial vision equipment, which can complete 10+ inspections such as flange surface flatness inspection, cavity length inspection, and solder joint inspection in 60 seconds, and can complete an average of 400-500 battery tray inspection tasks per day, which greatly improves the overall efficiency compared with manual inspection, and more than doubles the overall efficiency of manual inspection.
Advantage 1: "Robot on-the-job" is more scientific
Handheld 3D scanning equipment is the first to be used for the battery tray inspection process, but in the actual operation process, the longer the time is engaged in high-repetitive, low-value-added work, the worse the accuracy and stability of manual operation. After the Elfin collaborative robot replaces the manual, it mainly realizes -
(1) More stable operation: The repeated positioning accuracy of the Elfin collaborative robot is as high as ±0.02mm, and the trajectory accuracy can reach ±0.5mm, and the robotic arm runs more stably and without any difference, and can complete the battery tray detection task with high quality according to the planned detection path.
(2) Almost zero jitter at the end: When the vision device is running, the subtle jitter also affects the detection accuracy; Based on advanced motion control algorithms and vibration suppression algorithms, the Elfin series of cobots greatly reduces the occurrence of vibration and greatly improves the detection accuracy of battery trays.
(3) Battery tray inspection is a boring but important process, and "machine substitution" can avoid potential problems such as "missed inspection" and non-standard detection by workers, and can also optimize manpower allocation.
Advantage 2: Simple operation, one-key opening
For customers, it seems that traditional industrial robots can also automate battery tray inspection, but after inspection, it is found that it is more complex to operate and requires special personnel to debug. The "simplicity" of the Elfin cobot is reflected in the fact that:
(1) Simple programming: using graphical programming, ordinary employees can quickly master; At the same time, it supports offline programming, which is not afraid of problems such as many detection points and complex actions;
(2) Support the setting of the detection track of the battery tray by dragging and teaching;
(3) The threshold for use is extremely low: workers only need to place the battery tray to be inspected in the detection area, and then the detection can be started with one click.
Advantage 3: Fast and non-inductive changeover
Cobots have obvious advantages in flexible production. In view of the different specifications and materials of battery trays, customers pay more attention to the production mode of small batches and multiple varieties. The Elfin series of robots can preset the detection trajectory and program one by one, so as to cope with the frequent product change of the battery tray inspection station, and now the production change has been realized without feeling, which greatly saves time and energy.
The power battery is the core component of new energy vehicles, which can account for up to 50% of the cost of the whole vehicle, and strengthening the detection of battery trays is conducive to improving the safety and reliability of electric vehicles. Han's Robotics will continue to leverage the advantages of "stability, accuracy, ease of use, and efficiency" to further promote the automation process of auto parts manufacturers.
