Waterproof testing: the lifeline to protect underwater safety
The swimming pool cleaning robot has a complex structure, including structural parts, transmission parts, control parts and cleaning parts. It relies on multi-sensor fusion algorithms to achieve intelligent underwater navigation, and completes cleaning tasks through the collaborative operation of motors, water pumps and roller brushes.

However, it has been in a corrosive water environment containing chloride ions for a long time and needs to withstand the continuous pressure brought by different water depths.Under such harsh conditions, waterproof performance has become the key to determining product life and user safety: the failure of any sealing link may trigger a chain reaction - internal circuit short circuit, functional paralysis, and lithium battery leakage causing safety accidents.
Customer demand: precise control under 100kPa pressure
A manufacturer of head-mounted swimming pool robots once faced a severe challenge: after the products rolled off the production line, a small number of them still needed to be repaired due to waterproof failure, which not only increased after-sales costs, but also caused hidden damage to the brand reputation.
The customer put forward clear testing requirements: air tightness testing of the six core components of the lithium battery, waterproof motor, traveling motor, electronic control box, infrared component, and motor quick-plug connector. The test pressure is 100kPa and must meet the highest waterproof level requirement of IP68.
Solution: High-precision air tightness detection
Core equipment
HC classic series high-precision air tightness detector

Tooling configuration
Double-station/single-station desktop tooling improves inspection efficiency;
Customized jig and sealing silicone accurately match the shape of the component to avoid pressure loss or loose sealing.

Technical Highlights
The test range covers -80~2500kPa, adapting to various pressure requirements;
The cumulative deployment of equipment exceeds 20,000 units, with high maturity and strong stability.
Solution core advantages
Intelligent detection system:Equipped with a 0.2% F.S high-precision sensor with a minimum resolution of 0.1Pa, it effectively reduces the impact of temperature and environmental changes on the detection results and eliminates missed and misjudged results.
Customized sealing fixture:Special fixtures are designed for special-shaped parts, and matched with aviation-grade standard sealing silicone, the "flexible packaging" of special-shaped products is achieved, which not only ensures absolute reliability of sealing, but also avoids product damage.
MES system docking:It supports interconnection with customers' existing production management systems to realize automatic uploading, tracing and analysis of detection data. The software supports secondary development to meet future iteration needs of new products and save maintenance and equipment replacement costs.
Full life cycle services:From solution design, equipment debugging to operation training, we provide full-process support from pre-sales to after-sales to ensure worry-free use.
Implementing customer value: building a strong brand moat
By introducing the Hirays air tightness detection solution, the customer has realized three core values:
Quality leap:The detection accuracy rate has been greatly improved, potential water leakage risks have been effectively intercepted, and the product yield rate has been significantly improved;
Reduce costs and increase efficiency:Duplex inspection, single piece inspection time ≤30 seconds, production line efficiency is greatly improved, and the equipment supports MES system docking and software secondary development, which can significantly reduce long-term operating costs;
Brand moat:Highly reliable waterproof detection reduces the after-sales failure rate and strongly supports the brand's high-end positioning.
