An automatic screw tightening machine is an industrial automation system that automatically feeds, positions, and tightens screws into products. The JHIMS machine uses servo motors, ball screws, and linear guides with ±0.02mm repeat accuracy. It is specifically designed for LED module assembly and electronics manufacturing, handling screws from M0.6 to M2.0 at speeds up to 5,000 screws per hour.

The machine handles screws from M0.6 to M2.0 for the 2P-LXS500 model, and M0.8 to M2.0 for the 2P-ZXS320 model. This covers most LED module assembly requirements. Custom configurations for non-standard screw sizes are available upon request — contact our engineering team for details.

The cycle time is 0.9-1.2 seconds per 2 screws. Maximum throughput reaches 5,000 screws per hour for single-station models (2P-LXS500) and 11,000 units per hour for dual back-to-back configurations (4P-ZXS320). Actual speed depends on screw size, product complexity, and program settings.

Yes. The adjustable fixture supports LED modules up to 500×500mm (2P-LXS500) or 320×320mm per station (2P-ZXS320). The cylinder fixture can be repositioned to accommodate different module sizes, and support blocks can be rearranged for various form factors. Multiple smaller modules can be placed on a single platform simultaneously.

Programming is done via the handheld controller. Create a new program by pressing the '#' key, switch input methods with '#' to enter a program name, then press Enter. Use the CCD camera and X/Y directional keys to align the red cursor with each screw hole center, then press the Location key to record coordinates. The machine stores up to 999 programs with 999 coordinate points each. CAD file import is also available. Watch Video 2 for a complete walkthrough.

Regular maintenance includes: cleaning the vibrating feeder and screw track weekly, checking and replacing the batch rod (a wearing part) when slippage occurs, inspecting pneumatic connections for leaks, calibrating the ring sensor sensitivity, and keeping the linear guides lubricated. Wearing parts like the working head nozzle and batch rod should be replaced after extended use. Refer to our Operation Manuals for detailed maintenance schedules.

JHIMS provides a standard 12-month warranty on all screw tightening machines. After-sales support includes online video training, remote technical assistance via WhatsApp/Teams, and optional on-site installation and training services. Spare parts and wearing components are always in stock for fast delivery.

Press and hold the Stop button, then press Menu 1 simultaneously to open Menu 4. Navigate to Page 4 (press Next Page three times), select Option 6 (Language Setting), press OK, then select Option 2 for English. The interface will switch automatically. The detailed steps are shown in Video 2.

Safety features include: emergency stop switch (immediate power cut), pneumatic clamping safety interlock, automatic reset-to-origin requirement on startup, cylinder movement safeguards, and automatic torque detection with alarm. Important: Always press the Reset button before powering off the machine — this returns the working head to its origin position and prevents it from falling onto the product.

Most customers recover their investment within 6-12 months. The machine reduces labor costs by approximately 50% (replacing 2-3 manual operators), increases production output by 40%, and reduces rework rates by 30%. A Shenzhen LED manufacturer reported doubling production volume with zero quality loss within 3 months of installation.
