LH-TC Tool Changer Helps BYD Boost New Production Capacity

Since 2013, China has maintained a leading position in the global industrial robot welding sector. With accelerated transformation in the manufacturing industry, demand for welding robots is surging, and quality requirements for intelligent welding are rising. In this context, the tool changer—an essential component of intelligent welding—plays a critical role in upgrading manufacturing capabilities. LH-TC has broken through technological barriers, offering domestic tool changers whose performance rivals or even surpasses that of international brands, showcasing the strength of Chinese intelligent manufacturing.

Among BYD’s nine major production bases, the LTC-0630F tool changer is widely used on welding lines. At BYD’s Xi’an factory, for instance, the LTC-0630F enables seamless switching between multiple tools at a single station, significantly improving workstation efficiency. Whether switching welding guns to grippers, welding gun to welding gun, gripper to gripper, or between aluminum spot welding and FDS/SPR, the LTC-0630F handles all scenarios with ease, fulfilling BYD’s demand for high-efficiency, flexible production lines.

Key Advantages of the LTC-0630F Tool Changer

The LH-TC spot welding tool changer is designed for automatic switching between different tools in robotic spot welding processes. With modules for high power, signals, servo, and more, it supports fast switching between various welding tools, improving welding efficiency and enabling flexible production line configuration.

Durable Cooling Water Module
Patented mechanical self-sealing ensures automatic sealing of water and air media when the master and tool sides of the changer are disconnected. This enables fast fluid connections between industrial robots, tools, welding guns, and fixtures.

Redundant Signal Design
LH-TC’s electrical signal module adopts an active static redundancy design to ensure high-quality and reliable signal transmission.

Air Pressure Loss Self-Locking
