Magnetic Type Automatic Screw Feeding Machine
CM-20M
The CM-20M is a handheld automatic screw fastening solution that integrates vibratory screw alignment, air-blow screw feeding, and trigger-activated fastening operation. This configuration allows operators to maintain a stable cycle time even when working at mobile stations or in multi-angle fastening applications.
After alignment, screws are delivered to the fastening point via air-blow feeding and positioned by a magnetic driver bit, ensuring stable alignment and improved positioning accuracy during the initial fastening stage.
During operation, the operator simply pulls the trigger, causing the driver bit to advance the screw and complete the fastening process. Since this fastening method does not require the front sleeve or fixture to press against the workpiece surface, it effectively reduces the risk of scratches or surface marks. This makes the CM-20M especially suitable for cosmetic parts, painted components, anodized surfaces, or products with surface protection requirements.
It should be noted that the positioning mechanism of the CM-20M relies on the driver bit’s ability to hold the screw magnetically. Therefore, only screws with magnetic properties are applicable. For non-magnetic screw materials—such as most stainless-steel screws—a push-down type fastening model without magnetic dependency is recommended to ensure stable feeding and fastening performance.

Features
◎ Trigger-Activated, Handheld Operation
Fastening is initiated by pulling the trigger, offering flexible handling. This design is suitable for workstations that require fine position adjustments or multi-angle fastening.
◎ Non-Contact Fastening Design
During fastening, the front sleeve does not need to contact the workpiece surface, reducing the risk of cosmetic defects or surface damage.
◎ Magnetic Screw Positioning
The driver bit holds the screw magnetically, improving alignment stability during the initial fastening stage.
◎ Torque-Based Feeding Control
The system advances the next screw only after fastening is completed and a valid torque signal is received, ensuring consistent fastening quality.
◎ Screw / Workpiece Counting Management
Supports air-blow counting and torque-based counting, and can be combined with workpiece counting to facilitate production quality and output control.

Robot Type Vacuum Pick-up Automatic Screw Feeder
CM-TABLE-V
The CM-TABLE-V system integrates a Japan-made Quicher screw presenter with a programmable XY desktop robot for automatic vacuum screw pick-up and placement. Screws are lined up and rotated to the vacuum pick-up point, where the nozzle collects and delivers them to each fastening position according to programmed paths.The system is ideal for automated screw fastening where operators only need to load/unload the workpieces, as the robot handles the entire screw fastening cycle. The vacuum nozzle and clamping system can be customized based on screw type and working conditions for consistent, stable operation.Equipped with a brushless torque-controlled screwdriver, the system can detect floating screws, stripped threads, and torque completion, ensuring fastening quality. The belt-driven stepper motor ensures low noise and high positioning accuracy (±0.02mm).
