Application of Smart Electric Screwdrivers in the Assembly of New Energy Battery Packs
2022-07-21
More than half of 2022 has passed. After enduring repeated pandemic-related shutdowns and disruptions to offline sales, global inflation, and a sharp surge in crude oil prices triggered by the Russia-Ukraine conflict, China’s new-energy vehicle market has experienced explosive growth. According to reports, China’s new-energy vehicle retail sales reached a total of 2.6 million units in the first half of 2022, representing a year-on-year increase of 120%. In particular, BYD’s sales surged by as much as 315%.
As the core component of electric vehicles, batteries are assembled into battery packs during the packaging stage using methods such as laser welding, ultrasonic welding, pulse welding, or by means of contact via elastic metal strips. Following assembly, the battery pack is mounted onto the electric vehicle primarily through components like nuts, bolts, cable ties, and cable harness clamps, thereby integrating it with other vehicle subsystems to form the powertrain. The battery pack features hundreds of screws, each varying in type and torque requirements. Moreover, it’s crucial to avoid under-tightening, omissions, or incorrect tightening of screws—tasks that pose significant challenges for assembly-line workers. worker It brings considerable pressure.
Car battery packs are generally quite large, with both length and width exceeding... 1 meter—standard positioning brackets cannot achieve large-span operations, and the stopping coordinates are randomly selected. Against this backdrop, our company has developed... Smart electric screwdriver And its Smart tightening System Precisely designed to handle such scenarios, this is an intelligent tightening system that enables large-span operations for battery packs and features leak-proof and error-proof functionality with no fixed base point for parking.
Smart electric screwdriver Commonly referred to as a smart screwdriver or smart screwdriver. Install Tightening with the smart electric screwdriver After system implementation, screws are tightened in sequence, and the torque for different screws is accurately switched, enabling leak-proof and error-proof functionality.
1. Implement scanning-based retrieval of corresponding tightening process parameters to prevent incorrect tightening.
2. Generate a traceable tightening result report for each product code based on the barcode.
3. Implement base-point-free coordinate positioning and tighten in sequence; prevent omissions.
A 4.3-meter arm span enables comprehensive, dead-angle-free coverage of oversized products.
5. Precise coordinate reconstruction and computation to achieve accurate positioning of screw holes.
