Description

Waterproof performance testing device and method for waterproof electronic product equipment

Technical Field

The invention relates to the technical field of performance detection, in particular to a waterproof performance testing device and a waterproof performance testing method for waterproof electronic product equipment, which can be used for performing waterproof performance tests on terminal equipment of various specifications such as waterproof watches, waterproof smart phones, waterproof tablet computers and the like, and provide waterproof testing equipment with high precision and high reliability.

Background

In order to measure the waterproof performance of a waterproof wristwatch, a general experimental method is to store an object to be measured in an airtight container, apply air pressure to the periphery of the object to be measured, measure the amount of deformation occurring on the surface of the object, and confirm the displacement of the amount of deformation to determine the waterproof performance of the object to be measured. However, this method is generally used for a measurement object having a high rigidity (for example, a water proof property that can withstand water pressure of 10m to 100 m) and a small surface area, such as a waterproof wristwatch. Compared with products such as a waterproof watch, terminal equipment such as a waterproof smart phone or a waterproof tablet personal computer has lower rigidity (for example, the terminal equipment can resist water pressure of 1-2 m and is waterproof) and has larger surface area. It is difficult to correctly determine the water-repellent properties of such products using devices specifically designed to determine the water-repellent watch properties. Therefore, even when a highly rigid object such as a wristwatch is measured by the same principle, it is necessary to use a waterproof test device different from a waterproof test device for measuring a less rigid object such as a smartphone. The present invention solves the above problems by controlling the test pressure and at the same time, making structural improvements in the setting of the deformation amount detector.

Conventionally, a device described in [ air tightness test device for wristwatch japanese patent No. 960021 ] has been generally used for such a waterproof performance test. Fig. 1 shows a schematic configuration diagram of the apparatus, and a specific test apparatus will be described below.

The gas pressurization source is a high-pressure gas tank capable of providing any gas pressure value required by the test or an air compressor capable of providing compressed air; 2. the air valve (electromagnetic valve) can boost the pressure in the airtight container to any set test pressure through intermittent opening and closing actions and can exhaust air at the same time; 3. the structure of the airtight container is designed to be capable of accommodating and bearing the object to be measured, has the pressure resistance performance capable of bearing the maximum test air pressure, and does not cause the structure to be damaged or deformed; 4. the pressure detector is a pressure sensor which measures the pressure in the closed container and converts the pressure into an electric signal; 5. the object to be measured is an object with a sealed structure, such as a waterproof watch; 6. the deformation detector is a displacement sensor which measures the deformation generated on the surface of the object to be measured and converts the physical displacement into an electric signal; 7. the control method is that the opening and closing actions of the electromagnetic valve are controlled by the signal transmitted by the pressure detector 4, and the electromagnetic valve is boosted to any set test pressure; then, by obtaining the displacement signal from the deformation amount detector 6, the control behavior of a series of actions of waterproof judgment is performed.

Fig. 2 indicates a flow chart of the above-described series of actions. When the deformation amount returns to the state before pressurization after the pressurization is completed, although the deformation does not occur at all or occurs in a short time, the state may be referred to as a leak state. On the other hand, when the deformation amount is gradually returned to the state before pressurization after the set pressure is reached, the leak state can be referred to as a small leak state. By performing a plurality of tests in succession, the object to be measured can be determined from a completely unsealed state to a minute leakage state. The specific determination operation is as follows.

(S1) the object 5 to be measured is carried in the airtight container 3. A susceptor needs to be placed in the airtight container 3 before carrying. The object 5 to be measured needs to be held stably when it is placed on the stage, and a portion where the deformation amount of the object 5 is to be detected needs to be held in vertical contact with a contact portion of the deformation amount detector.

(S2) the pressure-increasing solenoid valve is actuated to start increasing the pressure in the airtight container.

(S3) the pressure in the airtight container 3 is measured.

(S4) it is confirmed whether the pressure in the airtight container 3 reaches a preset arbitrary test pressure value.

(S5) when the pressure in the airtight container 3 reaches a predetermined arbitrary test pressure value, the solenoid valve for pressurization is closed.

(S6) the amount of deformation is measured.

(S7) if the deformation amount satisfies the leak judgment condition, it is judged that the leak is large and the process proceeds to S13.

(S8) the steps from S3 onward are repeated within a predetermined large leak determination time, and after the large leak determination time has elapsed, the process proceeds to a small leak determination stage from S9 onward.

(S9) when no large leak is detected under any test pressure, the deformation amount at that time is defined as "0", and the deformation value is measured based on this.

(S10) if the value of the deformation amount satisfies the leak detection condition, the leak detection is detected as a leak, and the process proceeds to S13.

(S11) the steps from S9 onward are repeated for a small leak determination time that is arbitrarily set, and after the small leak determination time elapses, the flow proceeds to step S12.

(S12) if neither large leak nor small leak is detected, it is determined as a good product, and the process proceeds to step S14.

(S13) if a large leak or a small leak is detected, it is determined to be defective, and the process proceeds to step S14.

(S14) the test is ended after the high-pressure gas in the pressurized container is removed.

Fig. 3 indicates the determination conditions and setting methods of the large leak and the small leak. The test pressure is set to an arbitrary value within the range of the maximum test pressure in consideration of the test conditions and the characteristics of the object to be measured in advance. Other determination conditions that need to be arbitrarily set are as follows. a. The large leakage determination value is set to be that no deformation is generated after pressurization; or a deformation recovery amount in the case where the maximum deformation amount generated before the set pressure is reached is recovered quickly although the deformation is temporarily generated. b. The small leak determination value is a deformation recovery amount in a case where the maximum deformation amount generated after the pressurization is stopped is gradually and slowly recovered. c. The large leak determination time is a time during which the large leak determination is continued. d. The small leak determination time is a time during which the small leak determination is continued. In both of the large leak and the small leak, it is necessary to set an arbitrary determination time, and if no airtightness defect is detected within both the determination times, the airtightness is determined to be good.

The above-described conventional methods have the following problems. That is, the target test pressure for a product such as a wristwatch is generally 10m to 100m water pressure, and the pressure range is about 100Kpa to 1 MPa. The target test pressure adopted by products such as smart phones and the like is generally 1-2 m water pressure resistance, and the pressure range is about 10-50 kPa. Therefore, if the pressure control is performed by the opening and closing operation using the same type of electromagnetic valve, if the pressure control is performed mainly in the range of 100Kpa to 1MPa, the pressure increase rate is excessively high and a technical difficulty arises in the case where the pressure control is performed in the range of 10Kpa to 20 Kpa. On the other hand, if the apparatus is used mainly in the range of 10kPa to 20kPa, it is found that the pressure-increasing rate is too slow and it takes a long time to increase the pressure when the pressure is adjusted in the range of 100kPa to 1 MPa.

To solve this problem, the most technically easy to realize and the least expensive method is to set a test pressure for each object to be measured in advance in a device such as a pressure regulator for gas pressure supplied from a gas pressurization source. In this way, the pressure increase control by the opening and closing operation of the solenoid valve is not required, and thus the item [7 control method (the pressure increase control by opening and closing of the solenoid valve is controlled by the signal obtained by the 4-pressure detector to achieve the arbitrarily set test pressure) ] in fig. 1 is not required.

However, when the opening and closing operation is performed only by using the gas valve 2 used in fig. 1, the inside of the airtight container is raised from the atmospheric pressure to a test pressure which is set arbitrarily at a burst and which improves the adhesion between the gaps of the object 5 to be measured, and the gap which should be detected to be small may not be closed and thus may not be detected, and an erroneous determination may occur. This is also referred to as a "pseudo-occlusion phenomenon" because the pseudo-occlusion of the object 5 is improved due to the influence of the test pressure, and is a factor of erroneous determination. As for the effectiveness of the method of controlling the pressure increase rate when the pressure is increased from the atmospheric pressure to the arbitrarily set test pressure, reference is made to another patent [ japanese patent No. 2925987 for air tightness test apparatus for wristwatch ] filed by the same inventor as the aforementioned [ japanese patent No. 960021 for air tightness test apparatus for wristwatch ].

The reason why the conventional test technique requires a different test apparatus for a test object having relatively high rigidity such as a wristwatch than for a test object having relatively low rigidity such as a smartphone is explained above. The invention aims to solve the problem that when a waterproof performance test is carried out on terminal equipment such as a waterproof watch, a waterproof smart phone or a waterproof tablet personal computer, the same test equipment is provided, and a waterproof test can also be carried out on waterproof products with completely different water pressure resistance.
