Application example of pet dog tracker air tightness detector

Speaking ofDog trackerThe first thing we should consider is still fall proof and waterproof, because dogs are not so obedient. They especially like to have fun outdoors, and often get caught in the rain or splash,Therefore, it is necessary to test the air tightness of dog tracker, which is related to the service life of such equipment.


This time, Harris technology will bring you the air tightness test of pet dog trackerOfIt is hoped that our case can inspire the manufacturers in the improvement of waterproof performance and waterproof technology of testing equipment. Here's the solution.

What hiris wants to detect this timeThe pet dog tracker is shown in the figure belowIt is rectangular in shape and tight in structure. The shell is coated with rubber paint and sealed as a whole without air filling port,Such a designIt can improve the waterproof performance to the greatest extent, but the structure and small volume of the overall seal are nottoLosslessSealing testOfBring inconvenienceSo the technical staff of HarrisIt is decided to use indirect detection method to customize the mold auxiliary detection for the dog tracker.The figure below showsPet dog trackerMold drawing of sealing tester.

The mold is mainly used for product fixation, to create a sealed and stable environment for testing, in order to achieve the goalHigh precision air tightness detection of tracker. When testing,holdTracking deviceIn the mold, after the upper and lower mold is closed, a sealed detection space will be formed, and the mold can also be protectedTrackerIt is not damaged in the test. At this time, after the tooling connected with the mold is started, a certain volume of gas is injected into the mold through the air source. When the air pressure is detected, the air supply is automatically cut off and the pressure is stabilized. At this time, the airtightness detection system of Harris technology will monitor the air pressure in the mold to determine the leakageAirtightSealing.The figure below showsPet dog trackerSealing testerTooling displayFig.

HarrisPet dog trackerThe air tightness tester is divided into three parts: tester, air source and tooling. Because the tester, gas source and tooling are self-contained, they cooperate with each other in the detection, but do not affect each other, which improves the accuracy of air tightness detection. With different tooling, different types and sizes of products can be detected, and the applicability of the equipment is high. The following is the actual picture of the air tightness detector.

3Pet dog trackerFunction introduction of air tightness tester


1. The tester can support leakage test, blocking test, positive pressure test, negative pressure test and other leakage test methods. The test range is wide, and users can choose according to their own detection needs.

2. Large size touch screen is used as the human-machine interface, which can easily monitor the test results and set various parameters in the process of waterproof test.

3. It has the alarm function of qualified and unqualified products, which can eliminate the possibility of manual misjudgment and misinspection.

4. Belt4Circuit switch input and output8It can accept the control of external sensors and switch buttons, and can control the external relay, solenoid valve and other executive components, so as to realize the full automation of the test conveniently.

5. Tester ownedtwo hundredBy setting the parameters of the subprogram on the touch screen, the user can connect different subprograms in series to form a test processI/OThe interface enables the leakage meter to receive control signals from external sensors and control external actuators (relays, solenoid valves, etc.). So as to realize the automation of the test process.

6. With test data recording function, test data can be downloaded toUDisk, and through the computer display.

7. With barcode scanning function, it can track and record defective products and repair situation; The function of upper computer.
