The sealing body 210 may be a sealant, a sealing ring, or the like, and is not particularly limited herein.

The detection device comprises a sealing detection device 1 and a processing unit 2;

Meanwhile, compared with the detection of the electrostatic protection capability, the tightness detection has relatively low operation requirements on technicians, and the cost of the detection device is relatively low, so that the electrostatic protection detection of the terminal equipment 100 in batches is facilitated.

The type of the first parameter value used for characterizing the tightness of the gap 200 is not exclusive, and in some embodiments, the first parameter value is an air pressure value, and specifically, as shown in fig. 1, the tightness detecting apparatus 1 includes a sealed cabin 300, an air pressure adjusting unit 12, and a detecting unit 13.

The air pressure adjusting unit 12 is taken as a vacuum pump for illustration: the processing unit 2 controls the air pressure adjusting unit 12 to pump the air pressure in the sealed cabin 300 to-100 kPa (where, -100kPa is a first air pressure value), if 5 minutes (where 5 minutes is a first time period) has elapsed, the air pressure in the sealed cabin 300 is-92.5 kPa (where 92.5kPa is a second air pressure value, that is, a first parameter value), and the processing unit 2 determines that the electrostatic protection capability of the medium 220 in the terminal equipment 100 to be detected is 12KV according to the air pressure value of the sealed cabin 300 at this time, which is-92.75 kPa; if the air pressure value in the sealed cabin 300 is-87.5 kPa after 5 minutes, the processing unit 2 further determines that the electrostatic protection capability of the medium 220 in the terminal equipment 100 to be detected is 10KV according to the air pressure value of the sealed cabin 300 at the moment of-87.5 kPa; if the air pressure value in the sealed cabin 300 is-60 kPa after 5 minutes, the processing unit 2 determines that the electrostatic protection capability of the medium 220 in the terminal device 100 to be detected is 8KV according to the air pressure value of the sealed cabin 300 at the moment of-60 kPa.

Taking the air pressure adjusting unit 12 as a pressurization air pump as an example, the processing unit 2 controls the air pressure adjusting unit 12 to pressurize the air pressure in the sealed cabin 300 to 50kPa (where 50kPa is a first air pressure value), if 5 minutes (where 5 minutes is a first time period) elapses, the air pressure in the sealed cabin 300 is 15kPa (where 15kPa is a second air pressure value, that is, a first parameter value), and the processing unit 2 determines that the electrostatic protection capability of the medium 220 in the terminal device 100 to be detected is 8KV according to the air pressure value of the sealed cabin 300 at this time; if the air pressure value in the sealed cabin 300 is 30kPa after 5 minutes, the processing unit 2 determines that the electrostatic protection capability of the medium 220 in the terminal device 100 to be detected is 10KV according to the air pressure value of the sealed cabin 300 at the moment; if the air pressure in the sealed cabin 300 is 40kPa after 5 minutes, the processing unit 2 determines that the electrostatic protection capability of the medium 220 in the terminal device 100 to be detected is 12KV according to the air pressure value of the sealed cabin 300 at this time.

The processing unit 2 may determine the electrostatic protection capability of the medium 220 in the terminal device 100 to be detected according to a predetermined relationship between the first parameter value and the second parameter value in the terminal device 100, which may be obtained through experiments, and which will be described in detail later.

The tightness of the gap 200 of the terminal device 100 to be detected is detected by adjusting the air pressure value in the sealed cabin 300, so that the damage to the components inside the shell 110 of the terminal device 100 to be detected is relatively small (the influence on the corrosion and the like of the components inside the shell 110 is small because air enters or is drawn out of the sealed cabin), and the influence on the service life of the components inside the shell 110 caused by the test is reduced.

The air pressure adjusting unit 12 and the detecting unit 13 may be integrated with the processing unit 2, or may be disposed separately from the processing unit 2, which is not limited herein.

In some embodiments, as shown in fig. 1, the air pressure regulating unit 12 is in communication with the capsule 300 through a conduit 400, and the detecting unit 13 is disposed on the conduit 400. Therefore, the phenomenon that the detection unit 3 is directly arranged on the sealed cabin 300 to cause poor sealing of the sealed cabin 300 is avoided, and the accuracy of the detection device is improved.

The first parameter value is not limited to a gas pressure value, and in other embodiments, the first parameter value is a liquid level height value.

It should be noted that: in order to prevent the liquid in the capsule 300 from remaining on the housing of the terminal device 100, the terminal device 100 needs to be dried after the detection is completed.

Taking the air pressure adjusting unit 12 as a pressurization air pump as an example for explanation: the processing unit 2 controls the air pressure adjusting unit 12 to pressurize the air pressure in the sealed cabin 300 to 50kPa, at this time, a first preset interval is set as [15kpa,50kpa ], if the air pressure value in the sealed cabin 300 is 15kPa (where 15kPa is a first parameter value) after 5 minutes, the processing unit 2 confirms that the electrostatic protection capability of the medium 220 in the terminal device 100 to be detected is qualified; if the air pressure value in the hermetic chamber 300 is 10kPa (here, 10kPa is the first parameter value) after 5 minutes has elapsed, the processing unit 2 confirms that the electrostatic protection capability of the medium 220 in the terminal device 100 to be detected is not qualified.

The processing unit 2 determines that the electrostatic protection capability of the medium 220 in the terminal device 100 to be detected is qualified by judging whether the first parameter value is within the first preset interval, so that the terminal device 100 with unqualified electrostatic protection capability can be screened in time to avoid flowing into the next production process. Meanwhile, compared with manual confirmation, the processing unit 2 is used for determining whether the electrostatic protection capability of the medium 220 in the terminal device 100 to be detected is qualified or not, so that the confirmation result is more accurate, the problem that deviation is easily generated in manual confirmation is solved, the processing efficiency is high, and the mass detection of the terminal device 100 is facilitated.

In some embodiments, each time the processing unit 2 confirms that the first parameter value of one terminal device 100 to be detected is within the first preset interval, it sends a signal indicating that the electrostatic protection capability of the medium 220 in the terminal device 100 is qualified, for example, sends a first signal to make a green indicator light flash; if the first parameter value is outside the first preset interval, the processing unit 2 sends a signal indicating that the electrostatic protection capability of the medium 220 in the terminal device 100 is not qualified, for example, sends a second signal to make a red indicator light flash. This makes it more convenient to remind the inspector to avoid confusing a qualified terminal device 100 with a non-qualified terminal device 100.

Therein, the relationship between the second parameter value and the first parameter value of the terminal device 100 may be stored in advance in the memory of the processing unit 2, which may be obtained through experiments. Specifically, a group of terminal devices 100 with different first parameter values may be respectively subjected to an electrostatic discharge test to obtain second parameter values corresponding to the different first parameter values, so as to obtain a relationship between the first parameter values and the second parameter values for characterizing the electrostatic protection capability of the medium 220; the second parameter value may be a withstand voltage value or a breakdown strength value of the medium 220.

The method for testing the electrostatic discharge comprises the following steps: the method comprises the steps of placing the terminal device 100 to be detected on an electrostatic test bed, carrying out air discharge or contact discharge tests on a plurality of test points around a gap 200 in the terminal device 100 through electrostatic discharge equipment (such as an electrostatic gun) after the device is placed, wherein each test point is subjected to discharge tests for multiple times, the discharge interval time of each time is more than or equal to 1s, the discharge times are not less than 10 times, for example, 4 test points can be selected at four corners around a screen, each test point is subjected to discharge tests for 20 times, after each time of electrostatic discharge, whether the display function of the display panel 120 is normal is checked, and then the next discharge test is carried out.

The electrostatic test stand is provided with a photoelectric sensor, an image sensor, and the like electrically connected to the terminal device 100 to be detected, and during the detection process, it can be determined whether the display function of the display panel 120 is normal through the photoelectric sensor, the image sensor, and the like, for example, a light intensity change of the display panel 120 of the terminal device 100 is converted into an electrical signal by using the photoelectric sensor to determine whether the display brightness of the display panel 120 is abnormal, a display image of the display panel 120 is obtained by using the image sensor, and the obtained display image is compared with the normal display image to determine whether the display image of the display panel 120 is abnormal.

Taking the second parameter value as the withstand voltage value of the medium 220 as an example, during the electrostatic discharge test, the discharge voltage may be changed from ± 2kV, ± 4kV, ± 6kV, ± 8kV, ± 10kV, ± 12kV, ± 14kV step by step, during the test process of a certain voltage class and after the test is finished, if it is judged by the photoelectric sensor that the display brightness of the display panel 120 is not changed, the control of turning on and off the screen is not abnormal, and the display panel 120 obtained by the image sensor has no bad phenomena such as no screen-splash, no white screen, no black screen, no stripe, no screen-shake, no screen-splash, etc., the terminal device 100 is considered to satisfy the current test voltage class; if at least one of the abnormal phenomena occurs during and after the test of at least one test point, the terminal device 100 is determined not to satisfy the current test voltage class, and then the maximum test voltage class that the terminal device 100 can satisfy is taken as the second parameter value of the terminal device 100, for example, the terminal device 100 does not satisfy the test voltage class of ± 12kV, and then the second parameter value corresponding to the terminal device 100 is ± 10kV.

The judgment of whether the display function of the display panel 120 is normal may be performed by a manual method, in addition to the judgment by the photo sensor and the image sensor, and is not limited herein.

The sealing performance detection apparatus 1 shown in fig. 1 will be described by taking as an example that the air pressure adjusting unit 12 is a booster pump: the three terminal devices 100 with the first parameter values of 15kPa, 30kPa, and 40kPa are respectively subjected to an electrostatic discharge test, so that the second parameter value (i.e., withstand voltage value) corresponding to 15kPa is 8kv, the second parameter value (i.e., withstand voltage value) corresponding to 30kpa is 10kv, and the second parameter value (i.e., withstand voltage value) corresponding to 40kpa is 12KV.

The above detection principle is equally applicable when the second parameter value is the breakdown strength value of the medium 220. After each discharge detection, a special discharge line is needed to perform electrostatic discharge processing on the terminal device 100 to avoid the damage of the device due to the accumulation of charges into high voltage caused by multiple discharges.

If the first parameter value of the terminal device 100 to be detected, which is obtained by the sealing detection device 1, is 40kPa, the processing unit 2 determines that the second parameter value of the terminal device 100 to be detected is 12kv according to the relationship between the second parameter value and the first parameter value in the terminal device 100, and 12kv is equal to the set threshold value, and then the processing unit 2 determines that the electrostatic protection capability of the medium 220 in the terminal device 100 to be detected is qualified.
