On July 2, 2025, at the "Entering Li Auto: Integration of Intelligent Manufacturing and Industrial AI" Technology Day event held at Li Auto Beijing R&D Center , Qiaotian Intelligence, an innovative enterprise in the field of industrial flexible connection technology, was invited to participate. Product Manager Yin "Flexible Switching Product Technology and Best Practices" theme for technical sharing, explaining how Qiaotian quick-change plates, industrial connectors, and magnetic mold change products achieve cost reduction and efficiency improvement in the automotive industry through technological innovation, enhancing production line efficiency and quality.
Mr. Yin, Product Manager of Qiaotian Intelligent Quick-Change Disk
01 Welding Scenario Application
Under the current trend of multi-model mixed-line production in the automotive industry, the waste of production capacity caused by the low efficiency of traditional production line switching has become a key bottleneck restricting the construction of digital factories. For example, in the welding process, traditional tool replacement and energy switching rely on manual labor, with cumbersome and time-consuming processes.
The Qiaotian Quick Change Plate consists of a main body, standard modules, and customized modules, enabling communication for grippers, welding guns, riveting guns, tightening guns, and vision cameras. It uses pneumatic quick switching, eliminating the need for bolt disassembly. Tool change time is reduced to approximately 10 seconds (efficiency improvement exceeding 99% compared to traditional methods).
During the case sharing session, Engineer Yin provided a detailed analysis of the application breakthroughs of Qiaotian Quick Change Plates in complex scenarios: "In a certain customer's prototype vehicle trial production project, we faced four core challenges: completing the total assembly of the white body and multi-type connection processes within limited workstations with fewer than 4 robots; a single workstation needed to switch 4 types of end-effectors at high frequency; simultaneously compatible with cold connection (riveting) and hot connection (welding) processes; and at the same time requiring the quick change plate to integrate the function of weld spot quality inspection." In the face of this complex requirement, Qiaotian achieved the project implementation through a combination of high-frequency load technology support, multi-process coupling design, and intelligent signal transmission system.
"Flexible switching technology is a key link in achieving intelligent manufacturing."
02 Stamping & Injection Molding Scenario Applications

In addition, in the process of rapid switching of automotive multi-model body panels and multi-variety production of interior parts, traditional stamping die replacement relies on bolt fastening/hydraulic locking, Qiaotian Magnetic Die Change System can replace hydraulic/bolt, forming a technical combination with complementary load-bearing capacity with the quick-change plate to quickly switch dies.
"Flexible switching technology is transforming the traditional time-consuming process of device switching into an efficient value creation process."
03 Assembly Scene Application
The prerequisite for achieving flexible production is automatic interconnection. In the automotive final assembly stage, Qiaotian Industrial Connector is applied throughout core processes such as chassis assembly, electrical system integration, and functional testing.

Bridgefield industrial connectors can be flexibly configured according to the production requirements of the production line, ensuring efficient switching between different workstations, as well as floating installation and easy disassembly and replacement. The product has a plug-and-socket life of over 100,000 cycles, ensuring stable output during long-term plug-and-socket connections and reducing customers' additional spare parts and operation and maintenance costs.
Currently, the Bridgefield Industrial Connector Series has integrated modules such as voltage/current, I/O signals, compressed air, high voltage, small-diameter air connectors, single-sided self-sealing connectors, etc., and supports user-customized configurations.
"With the upgrading of the flexible demand of production lines, the flexible switching system has become a key infrastructure in the intelligent manufacturing system."
Qiaotian Intelligence is committed to providing reliable technical support for the mixed-line production of multiple vehicle models by automobile manufacturers, and promoting the continuous evolution of the automotive manufacturing industry towards flexibility and digitalization.
