Winding Machine Operation and Maintenance Procedures

I. General Provisions

Article 1 — Purpose

To standardize winding machine operation and maintenance behavior, ensure equipment safety, stability, and efficient operation, extend equipment service life, guarantee product quality and operator personal safety, these procedures are established based on relevant national mechanical equipment management regulations, industry standards, and enterprise internal equipment management systems.

Article 2 — Scope

These procedures apply to all models of automatic and semi-automatic winding machines in the company, including but not limited to parallel winding machines, ring winding machines, flyer winding machines, voice coil winding machines, etc. All activities involving winding machine operation, daily maintenance, periodic maintenance, and fault handling must comply with these procedures.

Article 3 — Management Principles

Safety first, prevention as priority; standardized operation, careful maintenance; individual responsibility, hierarchical management.

Article 4 — Key Terminology

• Operator: Personnel who have undergone professional training and passed assessment, authorized to perform daily winding machine production operations.
• Maintenance Personnel: Personnel with corresponding qualifications responsible for winding machine inspection, care, and repair as professional technical staff.
• Daily Care: Routine maintenance work including cleaning, inspection, and lubrication performed by operators before, after, and during each work shift.
• Periodic Maintenance: Systematic preventive maintenance work including inspection, adjustment, and replacement of wearable parts performed by maintenance personnel at predetermined intervals.
• Critical Components: Components directly affecting winding precision, equipment stability, and safety, such as main shaft system, wire arrangement system, tension control system, and control system.

II. Organization and Responsibilities

Equipment Management Department Responsibilities

• Formulate, revise, interpret, and supervise the execution of these procedures
• Organize training and assessment for winding machine operation and maintenance
• Develop annual and monthly maintenance plans and supervise implementation
• Responsible for winding machine major repairs and technical upgrades

III. Daily Operation Procedure

1. Turn on the winding machine power switch
2. Check that the winding machine is in normal working condition
3. Place electronic components requiring winding onto the winding machine
4. Adjust the winding machine winding head according to winding process requirements
5. Start the winding machine and monitor the winding process

IV. Daily Maintenance and Care

4.1 Pre-Operation Checks

• Carefully inspect the worktable, wire arrangement guide rails, and all main sliding surfaces
• Remove any obstacles, tools, or debris — must be cleaned and wiped
• Verify proper tension settings and wire guide alignment
• Check lubrication points for adequate oil levels

4.2 During Operation Monitoring

• Monitor winding quality continuously
• Listen for abnormal sounds or vibrations
• Check wire tension consistency
• Observe wire arrangement uniformity

4.3 Post-Operation Procedure

• Clean the machine surface of debris and dust
• Record operating parameters and production counts
• Report any anomalies to supervisors
• Disconnect power after complete shutdown

V. Periodic Maintenance

5.1 Weekly Maintenance

• Clean wire guide rails and apply specialized lubricant
• Check belt tensions and adjust as needed
• Inspect all electrical connections for security

5.2 Monthly Maintenance

• Calibrate tension control system
• Check main shaft bearing condition
• Clean electrical control cabinet filters
• Verify all safety interlocks function correctly

5.3 Quarterly Maintenance

• Inspect and clean all drive components
• Check wire guide mechanism for wear
• Verify control system parameter accuracy
• Replace worn bearings and seals as needed

VI. Safety Operation Requirements

1. All maintenance work must be performed with power disconnected and lockout/tagout applied
2. Never touch rotating parts during operation
3. Wear appropriate personal protective equipment
4. Keep work area clean and free of obstacles
5. Emergency stop buttons must be tested at start of each shift
