Project Overview
A professional industrial automation manufacturer in Southeast Asia focuses on the production and upgrading of automated optical inspection (AOI) equipment for electronic components. In the original equipment design, the traditional rotary motor plus screw transmission structure led to complicated mechanical clearance, low repeated positioning accuracy, and obvious operating vibration. During high-frequency short-stroke reciprocating inspection, the equipment was prone to position deviation, resulting in unstable shooting and inaccurate detection data. In addition, the customer’s production equipment needs to run continuously for a long time, requiring the drive components to have stable thrust output, low noise, and high durability to meet the high-precision inspection standards of electronic chips and circuit boards.
Customer Pain Points
Traditional transmission structures had mechanical gaps that affected overall positioning accuracy; severe operating vibration interfered with the precision shooting of industrial cameras, resulting in low detection accuracy and high false detection rate. The original driving structure had slow response speed, which restricted the overall operating efficiency of the inspection equipment. Moreover, the traditional structure had many wearing parts, requiring frequent maintenance and calibration, which increased equipment downtime and after-sales cost for the customer.
Our Solution
According to the customer’s high-precision inspection scenario, we provided customized high-performance linear stepper motor solutions. Different from traditional rotary motors, our linear stepper motors adopt an integrated direct-drive structure, which directly converts stepping motion into linear thrust, effectively eliminating mechanical transmission gaps. The optimized magnetic circuit and screw precision processing technology ensure ultra-smooth reciprocating motion, realizing micron-level repeated positioning accuracy. The motor features low vibration, low noise, and fast response speed, which perfectly adapts to high-frequency start-stop and short-stroke precise positioning requirements. At the same time, we matched professional driving parameters and conducted motion curve debugging to ensure stable coordination between the motor and the customer’s visual inspection system.
Project Effect
After applying our linear stepper motors, the positioning stability and inspection accuracy of the customer’s AOI equipment have been comprehensively improved. The problems of equipment vibration and detection deviation are completely solved, the product false detection rate is greatly reduced, and the overall equipment operation efficiency is increased by more than 20%. The integrated linear drive structure reduces mechanical wear and failure points, extending the service life of core components. The equipment no longer needs frequent shutdown calibration and maintenance, effectively reducing the customer’s operation and maintenance costs. With stable product performance and professional technical support, we have become the long-term fixed supplier of linear stepper motor solutions for the customer’s series of inspection equipment.
