As an outdoor security product, outdoor cameras are used in harsh environments and need to work normally in windy and rainy weather.The waterproof level of outdoor cameras needs to reach IP67 level, so manufacturers will perform IP67 waterproof testing on the cameras after the camera is assembled.In this article, Hai Ruisi will introduce to you the test results of dual-station outdoor camera air tightness testing equipment.

in the countryAir tightness testing equipmentBefore the development was immature, some manufacturers used imported air tightness testing equipment, and some used the water soaking method to conduct air tightness testing.However, the imported instruments are very expensive and the after-sales service is very inconvenient. Although the water immersion test is cheap, it is troublesome to operate and is not suitable for the batch air tightness test requirements of the factory.

The positive and negative pressure air tightness testing equipment launched by Hairuis Air Tightness Tester to adapt to market demand can accurately detect small leaks of products, with a measurement accuracy of up to 1pa, and supports two testing methods: positive pressure inflation testing and negative pressure vacuum testing.And according to different customer testing requirements, there are three pressure instruments to choose from: high, medium and low. The test range is from -100kpa ~1500kpa.

Testing requirements for outdoor camera customers:

The customer's output is relatively large, with an average daily output of two thousand outdoor cameras. A single-station air tightness tester cannot meet the customer's testing output. Hairis Technology customized this non-standard outdoor camera air tightness testing equipment for the customer. It can test two products at the same time, and the two work stations independently determine the leakage of the product. Both parties are not affected, and the air tightness test results are accurate.

At the same time, one instrument, two workstations, and only one operator are needed, saving human capital and saving testing costs for manufacturers.

The test parameters of outdoor security camera dual-station air tightness testing equipment are as follows:

1. Air tightness detector: Hairis HN pilot series instrument. Hairis pilot series is an instrument specially designed by Hairis for the automation field.It has very high flexibility and scalability.With modular design, the control system and execution part are independent.It can realize a system to control multiple execution modules to form a multi-channel test.

2. Dual-station camera air tightness testing equipment: an integrated equipment composed of HN embedded air tightness detector and tooling.

3. Test pressure range selection: The customer wants to use positive pressure for testing. The test pressure range selected for the customer is the standard range of 0-150kpa.

4. Test pressure: Because the waterproof level the customer wants to test is IP67, a test pressure of 12kpa is set for the customer.

5. Test time: The internal space of the product we want to test is relatively large, the air intake time is 7s, the voltage stabilization time is 5s, the test time is 7s, the complete time to test two products is 19s, and the average time to test one product is 10s.

HNembeddedAir tightness detectorFeatures

① High flexibility, functions can be added or deleted according to needs.

② Strong scalability, multiple sets of sensors.

③ Multi-channel tests can be quickly formed, greatly shortening the automated development cycle.

④ The analysis control system can use various methods such as industrial control computers plus control cards or embedded systems to facilitate the docking and implementation of the MES system.

 ⑤ The screen size supports customization. The embedded system comes standard with 7" and can be customized with 10.4", 12" or 15"; the screen size of the industrial control computer is not limited.The standard configuration adopts the full-function valve island of Hai Ruisi, with two pressure forms, positive and negative, and 8 test methods; the two pressure forms and five test methods can be programmed into more than 20 test functions.

⑥ Multiple communication protocols and interfaces: built-in RS232 and RS485 serial ports, USB2.0 interface, external I/O control port.

⑦ Optional barcode scanning function and host computer software facilitate product data management and quality traceability, and the instrument history record can reach up to 500,000 items
