Automatic Screw Feeder with telescope screwdriver set

CM-40

The SEALS CM-40 Automatic Screw Feeder is designed for speed, stability, and convenience. It integrates high-precision jaws, a reliable automatic feeding system, and Japanese-made torque-controlled pneumatic or electric screwdrivers to significantly enhance screw fastening speed and production efficiency. The screw jaws are custom-designed based on the customer's screw type and working environment, ensuring smooth and stable operation. SEALS also provides screwdriver model recommendations tailored to your specific screw and workpiece characteristics to ensure optimal fastening results. The material hopper adopts an up-and-down pushing board design to minimize screw surface scratches and keep feeding noise to a minimum. Combined with a fiber optic control system, the feeder intelligently stops when the chute is full, saving power and further reducing noise. The air blow feeding mechanism enables the next screw to be delivered to the jaw within 0.5 seconds—often before the operator moves to the next fastening point—greatly improving cycle time. A horizontal vibration chute is available to improve feeding performance for lightweight screws, painted screws, or screws with washers. The telescope-type screwdriver delivers consistent downward force directly into the sleeve of the screw, making it particularly suitable for self-tapping screws and wood screws. For automation integration, the screw feeder can be triggered via a dry contact to blow one screw per cycle. The screwdriver can also be mounted on a cylinder to enable vertical fastening strokes in fully automated assembly systems.

Equipped with an auto bit-pushing function, the CM-B1 supports horizontal screw fastening, making it ideal for inline applications on conveyor belt assembly lines. This feature allows screw fastening to be done directly in-line rather than offline, significantly reducing handling time and increasing throughput. To accommodate the narrow spaces near connectors, the screw jaws are designed extra-thin to avoid interference with VGA, DVI, or similar connector structures, while still securely aligning with the screw holes for precise fastening.

Programmable VGA, DVI Card Automatic Screw Feeder Machine

CM-40AUT

The SEALS CM-40AUT is a professional, programmable automatic screw feeder specifically engineered for assembling VGA, DVI, and other interface cards. Designed to handle two or four standoff screws per board, it offers a teachable positioning system, allowing operators to store up to 200 sets of fastening positions—ideal for high-mix, low-volume production environments. To accommodate narrow screw locations near VGA and DVI connectors, CM-40AUT adopts extra-thin jaws that ensure accurate alignment without interference. Similar to other SEALS models such as CM-30T, CM-40T, and CM-B1, the CM-40AUT features an ergonomic auto bit-pushing mechanism, which enables smooth horizontal fastening without requiring operators to manually press or hold the PCB—making it especially suitable for use on conveyor belt systems. For integration into fully automated production lines, both CM-40AUT and CM-B1 models can be incorporated with XY tables, SCARA robots, 6-axis robots, or other customized auto assembly equipment. The automation versions also support I/O signal communication, allowing seamless control and feedback with central control systems.

Robot Type Automatic Screw Feeder

CM-TABLE

The SEALS CM-TABLE series is a programmable, robot-type automatic screw fastening solution designed to reduce manual labor and improve process consistency. By integrating Japanese JANOME desktop robots with precision screw jaws, torque-controlled electric/pneumatic screwdrivers, and intelligent screw feeding systems, CM-TABLE delivers high-speed, high-precision, and highly repeatable performance, ideal for high-mix, low-volume production environments. Screw fastening points and motion paths can be fully programmed and stored in up to 255 modules (or 30,000 points), allowing rapid changeover and support for flexible production lines. The system supports real-time error detection—including screw shortage, torque achievement, and stripped-thread detection (optional)—to ensure consistent quality and reliable operation. Depending on the application, SEALS offers both belt-driven XY systems with stepper motors and ball-screw-driven models powered by servo motors, providing optimal configuration for speed or precision. A range of working platform sizes (200×200mm to 510×510mm) is available to accommodate various workpiece sizes. With features like data collection, programmable control, and automation readiness, CM-TABLE helps standardize the screw fastening process and ensures high stability, independent of operator influence.

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).
