Application of EP3L-S in Vehicle Body Workshop

In application, the automotive body process requires the use of special fixtures to apply NVH anti noise adhesive on the body sheet metal parts after they are formed and before painting, and to cooperate with robots in the handling and welding processes to form a body component processing production line. In the compact car body workshop with a production line layout, collaborate with other large robots to complete the spraying process.

2、 Process requirements
1. 5~10kg load capacity, complementary to Faunc large-scale robot collaborative operation process
2. Using EtherCAT bus control
3. 24/7 uninterrupted operation
4. Perfect anti-collision mechanism, lightweight operation of all aluminum body

3、 System solution
1. The control system adopts KEBA robot controller CP505A+6 EP3L-S joint servos integrated into one robot body
2. Servo power range covers 100W~0.75kW

4、 Advantages of the plan
1. Collaborative robots have inherent advantages in lightweight loads and range of motion, thanks to modular joint design, small size and high integration, and a much wider operating range than ordinary 6-joint robots
2. Installation and fixation are extremely simple, and the electrical cabinet is only the size of a computer case
3. Standard EtherCAT protocol support, fully compatible with various customized requirements, such as controller online modification of SDO, support for feedforward setting of robot dynamics models, etc
4. Support manual drag and drop teaching, as well as collision detection function
5. Support network FOE upgrade, one Ethernet cable can upgrade all serial drivers

5、 Equipment Description EP3L-S
1. Voltage: DC 48V
2. Power: 0.1kW~0.75kW
3. Communication interface: EtherCAT, minimum synchronization period of 125 μ s
4. Control mode: Supports CSP, CSV, CST, where CSP mode is used for joint positioning and CST mode is used for robot drag and drop teaching
5. Supports up to 23 bit multi turn absolute value encoder
6. Direct current sampling technology, no need for isolation, more compact design
7. Adopting high-performance ARM+FPGA, a four layer circuit board integrated design with high reliability, higher integration, higher reliability, lower cost, lower power consumption, and smaller size
