Pain Points & JHIMS Solutions

Rework & Disassembly Bottlenecks

  • Screw removal and rework are still done by hand — operators spend 10–20 minutes per board unscrewing defective units
  • Manual removal damages threads and pads, turning a repair into a scrapped panel
  • Large-format products (up to 500×500mm) are too heavy and awkward for handheld screwdrivers
  • Torque varies per operator, causing loose joints, cross-threading and field returns
  • No record of which screws were reworked, by whom, or at what torque
  • Slow changeover between product variants — manual fixture and program setup eats 15–30 minutes
  • Separate tightening and disassembly stations double floor space and equipment cost

JHIMS ZM500 Automation Solutions

  • One machine tightens AND removes screws — switch modes in the touch screen, no second station
  • Controlled unscrewing torque and depth detection protect threads and pads during rework
  • 520×520×100mm travel handles LED cabinets, EV battery trays and large PCB assemblies up to 500×500mm
  • Servo driver keeps torque consistent within ±3% on every screw, tighten or loosen
  • Touch screen logs torque, turns, screw position and NG events — full rework traceability
  • 1,000-program memory with camera-assisted teaching: product changeover in under 5 minutes
  • One operator runs 2–3 machines — 3–5× labor saving versus manual stations

Product Overview — ZM500 Screw Tightening and Removal Machine

JHIMS ZM500 desktop screw tightening and removal machine
JHIMS ZM500 screw tightening and removal machine

The ZM500 screw tightening and removal machine is a blow type screw locking machine that combines automated screw tightening and screw removal in one desktop station. The 3+1-axis system reaches ±0.025mm positioning accuracy at 0.9–1.2 seconds per screw, handles panels up to 500×500mm, and stores 1,000 product programs — so switching between fastening, loosening and rework operations takes minutes, not hours. A servo electric driver with real-time torque monitoring, a blow-type pneumatic feeder with precision vibrating disk, and camera-assisted point teaching make it a fit for LED modules, automotive electronics, medical devices and large-format PCB assemblies. The dual fasten/remove operation mode is the standout: the same machine tightens production screws and unscrews components for rework or repair, eliminating a second manual disassembly station.

Built on HIWIN linear guide rails with an Inovance servo motor system, AIRTAC pneumatic components and CHINT electrical parts for 24/7 industrial reliability.

Applications: the ZM500 automates screw tightening and removal for LED display modules, automotive electronics, consumer electronics, medical devices, industrial control panels, new energy products and telecommunications equipment.

Industry-Specific Screw Tightening & Removal Solutions

Consumer Electronics Assembly

For smartphones, tablets and wearables, the ZM500 drives M0.8–M1.7 micro-screws at 0.9–1.2 sec/screw on a 3+1 axis platform. Beyond fastening, it also removes screws — a dual capability that simplifies disassembly and rework in high-mix EMS environments. The servo electric driver holds exact torque, eliminating loose internal screws, and camera-assisted alignment keeps changeover fast between product variants.

Automotive Electronics

ECU housings, BMS controllers and ADAS modules require torque traceability for IATF 16949. The ZM500 touch screen records torque, turns and NG events per screw position, giving automotive audits complete documentation. Depth detection verifies correct seating on vibration-prone PCBs, and the removal function supports service and rework operations that other fastening machines cannot handle.

LED Module Manufacturing

LED modules and drivers on aluminum-substrate PCBs need careful torque control to avoid board damage. The ZM500’s programmable servo driver applies per-position torque profiles — gentle for thin substrates, firm for thick heat sinks. With 520×520mm effective travel, it handles large LED panels and backlight units that exceed desktop-station limits. The blow-type feeder suits clean, precise screw placement on reflective surfaces.

Medical Device Assembly

Medical device assembly demands zero-defect fastening with complete traceability. The ZM500’s NG detection and depth verification check every screw, while one-to-one fixture mode ensures consistent positioning for Class II and Class III devices. Full data logging supports FDA 21 CFR Part 820 and ISO 13485 quality systems. The screw removal function also aids in rework and repair of rejected assemblies.

Screw Tightening & Removal Technology Guide

Understanding screw tightening and removal technology helps production engineers optimize the final mechanical fastening step. Below is a comprehensive technical reference.

Blow-Type Feeding & Removal

The blow-type feeding system uses compressed air (0.55–0.65MPa) to carry screws from the precision vibrating disk through a blow tube to the nozzle. It handles small screws from M0.8 to M1.7, with a circular vibrator and precision separating cylinder delivering exactly one screw per cycle at 99.8%+ feed reliability. The reverse-drive removal function loosens and extracts screws for disassembly, rework and recycling operations.

Servo Torque Control

The servo electric driver provides closed-loop torque control — more consistent than pneumatic screwdrivers. Key parameters include rotation speed (RPM), lock turns to full seating, and target torque (Nm). Real-time monitoring flags an NG event, pauses and alerts the operator when torque leaves the set window, preventing under-tightening (loose screws) and over-tightening (stripped threads) in both fastening and removal modes.

3+1 Axis Precision Motion

The 3+1 axis motion system — three driving axes plus a Y-axis auxiliary — delivers ±0.025mm positioning accuracy with HIWIN linear guides and Inovance servo motors. X/Y travel spans 520×520mm for large boards and panels, with a 100mm Z-axis stroke for screw driving depth. Smooth acceleration/deceleration profiles minimize vibration during high-speed point-to-point movement, keeping repeatability at ±0.025mm.

Vision Alignment & Program Storage

The integrated camera captures fiducial marks or screw-hole features for automatic coordinate correction, compensating for fixture tolerances and PCB warpage. Repeatability holds at ±0.025mm. Up to 1,000 product programs are stored on the touch screen controller — switch between products by recalling a program and verifying screw positions, with no manual measurement or re-teaching.

Manufacturing Best Practices Guide

Maximize your ZM500’s performance and uptime with these operational and maintenance guidelines.

Daily Startup Checklist

1. Verify air pressure at 0.55–0.65MPa. 2. Check vibrating disk screw level — top up if below 30%. 3. Run 5 test cycles and verify torque readings on the touch screen. 4. Inspect nozzle for wear or debris. 5. Verify camera alignment with a reference product. 6. Check blow tube for kinks or blockages. 7. Record baseline torque values for SPC trending.

Preventive Maintenance Schedule

Daily: Clean nozzle tip, empty NG screw collection tray. Weekly: Clean vibrating disk bowl, inspect blow tube, lubricate Z-axis guides. Monthly: Calibrate torque sensor, verify XY positioning accuracy, clean camera lens. Quarterly: Replace air filters, check electrical connections, full system calibration. Annually: Comprehensive service by a JHIMS-certified engineer including servo driver inspection and guide rail replacement if needed.

Changeover & Program Recall

1. Recall the product program from the 1,000-program library. 2. Swap to the product’s dedicated one-to-one fixture. 3. Verify screw positions with camera-assisted teaching — typically under 2 minutes. 4. Run 5 validation cycles and check torque readings. 5. When switching screw sizes, replace the vibrating disk track and nozzle tip. 6. Log the new product’s torque baseline. Target changeover: under 5 minutes.

Environmental Requirements

Operate in a clean, dry environment at 10-35°C with 30-70% relative humidity (non-condensing). Avoid excessive dust, which can clog the vibrating disk mechanism. Place the machine on a level, vibration-free workbench. Compressed air must be filtered and dried — moisture in the air line causes screw feeding inconsistencies. Power supply must be stable AC 220V ±10%, 50Hz.
