Bosch Automotive Electronics has upgraded its ECU (Electronic Control Unit) assembly equipment with high-precision rotary indexing tables to achieve synchronous accurate positioning across multiple workstations. Driven by a divider, the equipment’s rotary table completes a 90° indexing movement within 0.3 seconds, conveying PCB boards sequentially to welding, dispensing, inspection and packaging stations. It delivers a repetitive positioning accuracy of ±0.02 mm, greatly boosting assembly efficiency and yield rate. Its backlash-free transmission design effectively eliminates the jitter issue inherent to traditional air cylinder indexing systems, maintaining stable performance during high-speed continuous operation. The annual failure rate is cut by 60%, meeting the stringent cycle time and reliability requirements of automotive electronics manufacturing.
