Ball Permeability Tester DR-TQX01

This device is widely used for the air permeability testing of balls. The ball is immersed in a container filled with water, and then compressed by a certain amount, which is 25% of the diameter of the test ball for footballs and mini footballs, and 10% for beach footballs. The ball can be rotated between dives. 

Main technical parameters

Core Technology Highlights and Functional Design

 Intelligent Compression Control System: Precisely match the ball type and restore the real force application scenario. The equipment is equipped with a servo electric cylinder + pressure sensor (accuracy ±0.5%), and through the three steps of "ball type recognition - compression amount calculation - constant pressure maintenance", it realizes "customized compression detection" for different types of balls:

✦ Automatic adaptation to multiple ball types:

Supports three mainstream ball types: standard size 5 football (diameter approximately 22cm), mini football (size 4, diameter approximately 20cm), and beach football (diameter approximately 21cm). The ball diameter is automatically measured by a laser distance sensor (accuracy ±1mm).

Based on FIFA standards, the compression amount is automatically calculated: for football and mini football, the compression amount = diameter × 25% (e.g., a size 5 ball is compressed by 5.5cm); for beach football, the compression amount = diameter × 10% (e.g., a beach ball is compressed by 2.1cm), avoiding manual conversion errors (traditional manual measurement deviation > 10%). 

Constant pressure maintenance and dynamic adjustment:

Compression speed: 1–10mm/s (adjustable), simulating different force application scenarios such as "rapid impact" (10mm/s) or "slow compression" (1mm/s);

After compression, it automatically enters the "constant pressure maintenance mode" (duration adjustable from 1 to 5 minutes) to ensure the detection of "air permeability under continuous pressure" (such as the risk of air leakage in a football under prolonged pressure during intense play);

The pressure sensor provides real-time feedback. If the pressure of the ball drops due to air leakage (e.g., from the set 100kPa to 95kPa), the system automatically replenishes the pressure to the target value to maintain consistent test conditions. 

 360° Rotating Inspection Table: No Blind Spots, No Hidden Bubbles

The equipment is equipped with an electric rotating table and a transparent observation chamber (material: anti-corrosion acrylic, thickness 10mm). It achieves "0-360° full-surface inspection" of the sphere through "uniform rotation + high-speed camera":

✦ Uniform Rotation Function:

Rotation speed: 1-5 revolutions per minute (adjustable), ensuring that every surface area of the sphere (seams, air valves, skin joints) can be submerged in water and exposed to the camera's field of view;

Supports "stopping at a fixed point" (if suspicious bubbles are found, rotation can be paused and magnified for observation), facilitating precise location of leaks (traditional manual rotation is prone to missing hidden areas such as seams). 

High-speed Bubble Capture System:

Equipped with a 4K high-speed camera (frame rate 240fps), and in combination with a "ring-shaped LED fill light" (adjustable brightness), it can clearly capture "microbubbles with a diameter of ≥0.1mm" (the human eye can only identify bubbles ≥1mm);

Machine vision algorithms automatically analyze the "generation position, quantity, and rate" of the bubbles (such as "1 bubble per second at the air outlet"), and output a "leakage level" (mild/moderate/severe), avoiding human misjudgment (traditional methods rely on experience, with a missed detection rate >20%). 

 Intelligent Data Management: From Detection to Reporting, Fully Traceable

✦ Real-time Data Visualization:

Equipped with a 10-inch touch operation screen (resolution 1920×1080), it displays core parameters such as "sphere diameter, compression amount, current pressure, rotation speed, bubble position" in real time;

Supports "detection process replay" (viewing video clips of any time period), facilitating the tracing of details such as "the 30th second of the seam of ball No. X started to leak" (traditional methods only provide "pass/fail" conclusions). 

✦ Report Generation and Export:

Built-in FIFA/GB/T 22831 standard thresholds (such as "no visible bubbles", "pressure loss within 24 hours ≤ 15%"), automatically determine "pass/fail" and mark the location of leaks (such as "poor sealing of the air nozzle");

Supports PDF/Excel report export (including video clips of the test, bubble analysis charts, and compliance conclusions), and data can be synchronized to the enterprise MES system (such as synchronizing "the pass rate of a certain batch is 98%" to the quality control end to trigger a re-inspection). 

 Multi-scenario Adaptability: From production lines to laboratories, flexibly meeting demands

✦ Production line batch testing mode:

Equipped with an "automatic loading robotic arm" (capable of holding 1 ball at a time), in conjunction with a "conveyor belt", a single machine can test 30-50 balls per hour (compared to only 10 balls per hour with traditional manual testing);

Supports "offline mode" (able to store 1000 sets of data without network) and "online mode" (real-time upload to the cloud platform for remote monitoring of production line quality). 

Laboratory R&D mode:

Optional "temperature/humidity environmental chamber" (temperature -20°C to 50°C, humidity 30% to 90% RH) can be equipped to simulate the changes in permeability under extreme conditions such as "low-temperature embrittlement", "high-temperature softening", and "moisture penetration" (for example, the leakage rate of a certain new type of ball bladder increases by 30% at 50°C and 90% humidity);

Supports "comparison testing" (simultaneous detection of 2 balls), and outputs a "Material A vs Material B leakage rate comparison" report (assists in R&D to optimize the formula). 

Application scenarios and customer value

1. Ball manufacturers: 80% improvement in production line quality control efficiency, with pass rate clearly visible

✦ Production line compatibility:

Seamlessly integrated with the ball production line's "forming - inflation - quality inspection" process, capable of testing 600-1000 balls per day per machine (based on an 8-hour workday), meeting the production demand of "20,000 balls per month" on a large scale;

The pass rate has increased from 90% (manual spot checks) to 99%, saving an annual rework cost of 300,000 yuan (based on an annual production of 240,000 balls). 

2. Third-party Testing Institutions: The "Golden Certificate" of Authority

✦ Compliance Support:

The equipment has been certified by the CNAS laboratory (China National Accreditation Service for Conformity Assessment), and the test reports comply with international and national standards such as FIFA and GB/T 22831;

It once helped a testing institution intercept "one batch of beach footballs (with a leakage rate over 20%)", preventing substandard products from entering the World Cup peripheral market. 

3. Material R&D Institutions: Accelerating Technology Iteration

✦ Research Support:

Simultaneously test the breathability of different bladder materials (such as butyl rubber vs. natural rubber) and different heat sealing processes (high-frequency heat sealing vs. cold bonding);

Output correlation reports on "material - leakage rate" and "process - sealing performance" (e.g., "The leakage rate of butyl rubber bladders is 50% lower than that of natural rubber"), assisting the R&D team in optimizing formulas (reducing the traditional manual testing time from 2 weeks to 10% of the original). 

Reliability and Maintenance

Structural Durability:

✦ The lifespan of the servo electric cylinder is ≥500,000 cycles (equivalent to continuous testing for 3 years, with an average of 100 balls tested per day);

✦ The transparent observation chamber is made of food-grade acrylic with a nano-coating (anti-corrosion and anti-yellowing), with a lifespan of ≥10 years.

Easy Maintenance Design:

✦ The equipment supports "automatic calibration" (verifying the compression accuracy through a standard airbag at startup each week, and automatically alarming when the deviation is >2mm);

✦ Self-diagnostic function for faults (displaying codes such as "compression abnormality" and "camera failure"), guiding quick repairs (average repair time <1 hour);

✦ A "drain valve" is equipped at the bottom of the observation chamber (draining water in 30 seconds) to prevent long-term water accumulation from causing chamber corrosion.

Operation Process (4-step Efficient Detection)

✦ Ball Recognition → Place the ball to be tested in the transparent observation chamber. The equipment automatically measures the diameter and recognizes the ball type (such as "size 5 football") through laser ranging;

✦ Parameter Setting → The system automatically matches the compression amount (e.g., 5.5cm for a size 5 ball). Users can customize "compression speed (5mm/s)", "constant pressure time (3 minutes)", and "rotation speed (2 revolutions per minute)";

✦ Start Detection → Click the "Start" button, and the equipment automatically completes the entire process: "filling water to submerge the ball", "compressing to the target amount", "uniform rotation", and "bubble capture";

✦ Result Output → The screen displays a "pass/fail" judgment (unqualified balls are marked with the location of the leak), and supports scanning to bind the ball number (e.g., "Ball No. 20250620-001"), with data automatically stored or uploaded. 

Precise pressure testing and comprehensive leak detection - with the meticulousness of a laboratory, we affix a "seal of reliable quality" to the air permeability of every ball.
