Mobile phones are now equivalent to our“The apple of your eye”, always hold it in the palm of your hand for fear that it will fall.If I accidentally drop it on the ground, I will pick it up immediately to see if it is damaged.Let me tell you, if it falls on the ground, it is fine. What if you fall into the water and see?No need for a mobile phone without waterproof function“Half disabled”Right?

Not to mention, this sentence may not be true!There are exceptions to everything, such as an American uncle’s iPhone 4.It is understood that this American uncle accidentally dropped his iPhone 4 into an icy lake while fishing a year ago.Because the weather was bad and the lake was frozen, he did not go to retrieve it.Later, he informed everyone on Facebook that his cell phone was lost.I don’t know whether it was God’s will or the iPhone 4 was destined to die. A year later, he found the iPhone 4 that he had lost in the same place.It’s really hard to find it. What’s even more amazing is that this phone can actually be turned on!Is it really that magical?In fact, this credit must be attributed to the waterproof mobile phone case. This is a product that has beenWaterproof testAfter putting on the waterproof mobile phone case, the mobile phone will have a layer of barrier from the lake water.In addition, the silt in the lake was very viscous and surrounded the mobile phones, forming a layer of“Waterproof membrane”.That's why this iPhone4 miraculously survived.

The above story tells us the importance of mobile phone waterproof cases, but that was before, and its waterproof level was just a concept. Now the mobile phone body itself can achieve IP67 and IP68 waterproof levels, but what is the focus of body protection? Do you know?Let’s analyze the key points of mobile phone waterproofing and the basic method of using an air tightness tester to test mobile phone waterproofing:

1. Mobile phone back shell Nowadays, mobile phone back shells will have cameras, flashes, and important antennas, and some will also have buttons, card trays, etc. Generally speaking, mobile phone back shells are the top priority in the waterproofing process of mobile phones.Make a mobile phone back caseWaterproof testerbecomes more important

2. The panel is the mobile phone screen. The most involved thing here is the home button. The home button is now mostly used for fingerprint unlocking, key operations and other functions. The home button needs to be pressed frequently, so its protection is very important.It is also necessary to useAir tightness detectorTested for waterproofing

3. Speaker: The waterproofing of this area is very important. If it is not handled well, the sound quality will be greatly affected. First, it must ensure that the sound can come out and not be sealed tightly. Second, it must ensure that water cannot enter from here.Therefore, it is necessary to do a good job in air tightness and waterproof testing of the speakers.

4. Charging position There are many charging methods now, including plug-in charging port, metal contact charging method, induction type, etc. No matter which one, because it is not integrated, you need to pay attention to waterproofing.A waterproof test is also required.

Now that we have done so many waterproofing and sealing processes, how do we do it?Waterproof testingWoolen cloth?You might say, can’t it just be soaked in water directly?Yes, this is a method, but it is very inappropriate if it is placed on the production line. First, it greatly affects the production progress and takes a long time; second, it is difficult to clean; third, if water enters, it will cause damage to the product; fourth, manual judgment will be wrong, not scientific and rigorous enough, and a series of other undesirable factors.So is there an instrument and equipment that can detect accurately, be time-efficient, and cause no damage to the product?The answer is yes. The waterproof tester produced by Shenzhen Hiraysi Automation Technology Co., Ltd. is a high-quality product for various sealing products.Air tightness and waterproof detector, especially for the seal detection of mobile phones and mobile phone peripheral accessories, which has been recognized by customers in the industry.Shenzhen Hiraysi Automatic Technology Co., Ltd. has many years of experience in waterproof testing. It has been committed to the research, development and production of waterproof testing and air tightness testing for various products for more than ten years.Today's new generationWaterproof testingThe system has been launched and has successfully entered the market, winning unanimous praise from customers.

Below we will introduce the waterproof tester of Shenzhen Hiraysi brand:

Equipment overview.

Waterproof detector, usually called air tightness testing equipment,Air tightness detector、Air tightness testing, air tightness testing, waterproof testing, waterproof testing, waterproof testing equipment, sealing testing equipment, sealing detectors, etc., mainly used for sealing product testing, IPX waterproof testing and identification.It integrates the control unit assembly, sensor unit assembly, test tooling, and execution module.The high-end models are equipped with built-in RS232 and RJ45 communication interfaces, allowing you to develop your own host computer system and monitor remotely. The host computer can automatically read test data and control the product to start testing.The test history data is saved inside the instrument and the test data can be traced and queried.The USB expansion interface can be used to export test history records, and can also be used to connect an external barcode scanner. The scanned barcode content and test data can be combined and saved.

The parameters of the new waterproof detector are as follows:

Air supply pressure: 0.4~1.2MPa

Power supply voltage: 220v/50hz or 110v/60hz

Pressure adjustment range: -40~-0.5KPa, 5~150KPa

Pressure adjustment accuracy: 0.1KPa

Pressure test range: -60~150KPa

Pressure decay test minimum resolution 1Pa

Minimum resolution of leakage flow test: 0.01ml/mi

Test principle

Use a certain pressure and a certain volume of compressed air to inflate the product. If the product has an inflation hole, supply air directly to the product's inflation hole. After charging for a certain period of time, cut off the air supply, and use the pressure sensor inside the instrument to monitor the pressure changes after the product is inflated. If the product does not have an inflation hole, design a mold to wrap the product, and then quantitatively inflate the product surface through the mold, cut off the air source, and use the pressure sensor inside the instrument to monitor the pressure changes after the product is inflated. Two productsWaterproof testThe schematic diagram is as follows:

Test method.

First determine the test standards, such as waterproof camera requirementsIP waterproof level test, IP67 protection standard.This is an international standard test requirement. The test method is relatively mature and I will not introduce it in detail. Currently, most high-pressure air tightness tests are non-standard customization. The test requirements are determined by the customer. The test standards need to be based on the product's use environment and sealing requirements. The product characteristics must pass experimental tests and the test data can be analyzed to obtain the test standards.The conventional testing method is to inflate the product, cut off the air pressure after it reaches a specified pressure, and then detect the air pressure inside the product. The detection data is collected and analyzed by the air tightness detection system to calculate the leakage amount and obtain the leakage value.Compare the leakage value with the standard value to determine whether it is qualified.It can be concluded whether the corresponding waterproof level is reached
