Automatic Electrode Production Equipment Long-Term Maintenance & Wear Parts Replacement Cycle Specification

Published: JULY 27, 2026 - Shanghai Zhichen Medical Technology Co., Ltd.

Continuous long-term operation of ECG and TENS electrode automatic production lines will cause gradual wear of transmission, gluing, die-cutting and sensing components. Timely standardized maintenance and regular replacement of vulnerable parts can effectively reduce equipment downtime, stabilize finished product yield and extend the overall service life of the machine. This article unifies daily, weekly, quarterly and annual maintenance operations and standardized replacement cycle of all core wear parts.

1 Daily Routine Maintenance Operation Standards

1.1 Residual Glue & Substrate Cleaning

After daily shutdown, wipe the glue dispensing head, roller surface and die-cut mold surface with special alcohol cleaning cloth to solidify hydrogel residue, prevent long-term glue buildup from causing uneven coating and electrode burr defects.

1.2 Transmission Belt Inspection & Lubrication

Check conveyor belt tension for deviation, clean surface dust, add a small amount of food-grade lubricating oil to guide roller bearings.

1.3 Touch Screen & Sensor Reset Check

Restart control system to clear temporary parameter deviation, test tension sensor and photoelectric switch induction sensitivity.

2 Weekly Deep Maintenance Items

Dismantle glue valve for full disassembly cleaning, remove internal dried gel blockages

Check all wire harness connectors for looseness and oxidation

Calibrate the substrate feeding horizontal correction device

Clean the air compressor filter element and drain water storage tank

3 Quarterly Precision Calibration Maintenance

Complete full machine precision calibration every three months, including gel thickness tolerance, die cutting size tolerance, snap riveting pressure, and record all calibration data for equipment maintenance archives.

4 Annual Overhaul Full Machine Inspection

Dismantle the main transmission box to replace aging lubricating grease, check servo motor operating current, inspect cylinder sealing rings for air leakage, and replace aging plastic pipelines.

5 Core Wear Parts Standard Replacement Cycle

5.1 Rotary Die Cutting Mold

Normal continuous production 800,000 to 1,000,000 pcs; replace when obvious burrs appear on electrode edges.

5.2 Glue Dispensing Valve & Sealing Gasket

Gasket: replace monthly; integral glue valve core assembly replace every 6 months to avoid glue leakage and uneven coating.

5. TENSion Sensor & Photoelectric Switch

Stable service cycle 12 months, replace when induction delay and feeding deviation frequently occur.

5. Conveyor & Pressing Rubber Rollers

Replace every 4 months after surface wear and glue adhesion cannot be cleaned.

5. Air Cylinder Seals & Pneumatic Pipelines

Sealing ring half-year replacement, plastic gas pipe annual replacement to prevent air leakage affecting riveting pressure.

5. Heating Constant Temperature Tank Components

Temperature sensing probe replace every 10 months, heating rod replace every 18 months.

6 Wear Parts Stock Suggestion

Factories with single production line can reserve one set of full vulnerable parts for emergency replacement; multi-line mass production workshops shall maintain 2-3 sets of spare molds, glue valves and sensors to avoid production shutdown caused by sudden component damage.

Summary

Strict implementation of layered maintenance and regular replacement of wear parts is the core guarantee for stable and long-term operation of electrode production equipment, effectively reducing production loss caused by sudden machine failure and lowering long-term factory equipment investment cost.
