In the production process of liquid camera, there is a situation that the liquid camera is damaged, so it is necessary to conduct quality inspection on the liquid lens of liquid camera to ensure the reliability of liquid lens.

[0003] In the production process of liquid cameras, how to quickly and accurately detect whether the liquid lens is leaking is a problem that needs to be solved urgently. Summary of the invention

[0004] The present application aims to provide a liquid camera detection device and a liquid camera leakage detection method to solve the technical problem of being unable to quickly and accurately detect whether a liquid lens is leaking during the liquid lens production process.

[0005] In order to solve the above technical problems, this application is implemented as follows:

[0006] In a first aspect, an embodiment of the present application proposes a liquid camera detection device, which includes: a clamp for clamping a liquid camera; an infrared transmitter and an infrared receiver, which are arranged on the side walls of the clamp; wherein the liquid camera includes a liquid lens, and when the liquid camera is clamped in the clamp, the infrared transmitter transmits a first infrared signal, which is received by the infrared receiver after reflection or transmission by the liquid lens, and the infrared receiver receives a second infrared signal, and when a first ratio of the first infrared signal to the second infrared signal satisfies a first preset relationship, it is determined that the liquid lens is leaking.

[0007] In a second aspect, an embodiment of the present application provides a liquid camera leakage detection method, which is applied to the liquid camera detection device of the first aspect, and the method includes:

[0008] When the liquid camera is arranged in a fixture of the liquid camera detection device, and when a start instruction of the liquid camera is detected, the liquid lens of the liquid camera is detected by the infrared transmitter and the infrared receiver of the liquid camera detection device to obtain a first infrared parameter;

[0009] The method of detecting the liquid lens of the liquid camera by using the infrared transmitter and the infrared receiver of the liquid camera detection device includes:

[0010] The infrared transmitter transmits a first infrared signal;

[0011] The infrared receiver receives a second infrared signal, where the second infrared signal is a signal of the first infrared signal after being reflected or transmitted by the liquid lens;

[0012] Wherein, when the first infrared parameter satisfies a first preset relationship, a first prompt message is displayed;

[0013] The first infrared parameter is a first ratio of the first infrared signal to the second infrared signal;

[0014] The first prompt information is used to prompt that the liquid lens is leaking.

[0015] In a third aspect, an embodiment of the present application provides an electronic device, which includes a processor, a memory, and a program or instruction stored in the memory and executable on the processor, wherein the program or instruction, when executed by the processor, implements the steps of the method described in the second aspect.

[0016] The liquid camera detection device in the embodiment of the present application includes: a fixture and an infrared transmitter and an infrared receiver arranged on the side wall of the fixture. Among them, the liquid camera includes a liquid lens. When the liquid camera is clamped in the fixture, the infrared transmitter transmits a first infrared signal, and the first infrared signal is received by the infrared receiver after being reflected or transmitted by the liquid lens. The infrared receiver receives a second infrared signal. When the first ratio of the first infrared signal and the second infrared signal satisfies the first preset relationship, it is determined that the liquid lens is leaking. Because the corresponding infrared parameters (i.e., the ratio of the first infrared signal to the second infrared signal) are different when the liquid camera is leaking or not leaking.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0036] Combine the following Figures 1 to 6 , describing the liquid camera detection device 100 provided in an embodiment of the present application.

[0037] like Figure 1 As shown, an embodiment of the present application provides a liquid camera detection device 100, which includes: a clamp 500, an infrared transmitter 510 and an infrared receiver 520; the clamp 500 is used to clamp the liquid camera 410; the infrared transmitter 510 and the infrared receiver 520 are arranged on the side wall of the clamp 500.

[0038] Among them, the liquid camera includes a liquid lens. When the liquid camera is clamped in the fixture 500, the infrared transmitter 510 transmits a first infrared signal, and the first infrared signal is received by the infrared receiver 520 after being reflected or transmitted by the liquid lens. The infrared receiver 520 receives a second infrared signal. When a first ratio of the first infrared signal to the second infrared signal satisfies a first preset relationship, it is determined that the liquid lens is leaking.

[0039] In the embodiment of the present application, the clamp 500 may be tubular, and the shape of the cross section of the clamp 500 is compatible with the shape of the liquid camera.

[0040] Exemplarily, the liquid camera may include a housing 400, which may be tubular and include two oppositely disposed open ends. The liquid lens is located in the housing 400, and may be disposed in the middle of the housing 400, or at an end of the housing 400, or near an end of the housing 400.

[0041] For example, Figure 4 As shown, the liquid lens 410 includes a liquid lens film 411, in which liquid lens liquid is enclosed.

[0042] Exemplarily, the liquid camera can be disposed in the middle of the fixture 500, or at the end of the fixture 500, or near the end of the fixture 500. For example, the housing 400 of the liquid camera can be disposed in the middle of the fixture 500.

[0043] In the embodiment of the present application, when the infrared transmitter 510 and the infrared receiver 520 are arranged on the side wall of the fixture 500 , the first infrared signal emitted by the infrared transmitter 510 can be reflected or transmitted by the liquid lens 411 , and the second infrared signal can be received by the infrared receiver 520 .

[0044] The first possible implementation is:

[0045] In the embodiment of the present application, the first ratio of the first infrared signal to the second infrared signal is an infrared parameter of the liquid lens.

[0046] It can be understood that when the liquid lens is not leaking, the infrared parameters when not deformed and the infrared parameters when deformed both satisfy an interval, that is, both satisfy a preset relationship. That is, the first preset relationship of the numerical values ​​corresponding to the infrared parameters when not deformed and the first preset relationship of the numerical values ​​corresponding to the infrared parameters when deformed can be the same or different.

[0047] In the embodiment of the present application, the first ratio of the liquid lens when it is not deformed and the first ratio of the liquid lens when it is deformed can be pre-detected and stored when the liquid lens is not leaking. In this way, it is possible to determine whether the infrared parameters meet the corresponding first preset relationship based on the infrared parameters detected by the liquid camera detection device (i.e., the first ratio of the first infrared signal and the second infrared signal), thereby accurately determining whether the liquid lens is leaking.

[0048] In the embodiment of the present application, the values ​​corresponding to the infrared parameters when the liquid lens is deformed include the values ​​corresponding to the infrared parameters when the liquid lens is deformed at different times. Since the focal length of the liquid lens can be adjusted by controlling the deformation of the liquid lens, the values ​​corresponding to the infrared parameters when the liquid lens is deformed include the values ​​corresponding to the infrared parameters of the liquid lens at different focal lengths.

[0049] The second possible implementation is:

[0050] In the embodiment of the present application, the infrared parameter of the liquid lens may also be the intensity of the second infrared signal.

[0051] Similarly, it can be understood that when the liquid lens is not leaking, the infrared parameters when it is not deformed and the infrared parameters when it is deformed both satisfy an interval, that is, the intensity of the second infrared signal when the liquid lens is not deformed and the intensity of the second infrared signal when it is deformed both satisfy a preset relationship.

[0052] The first preset relationship between the numerical values ​​corresponding to the infrared parameters when not deformed and the first preset relationship between the numerical values ​​corresponding to the infrared parameters when deformed may be the same as or different from each other.

[0053] In the embodiment of the present application, the intensity of the second infrared signal when the liquid lens is not leaking and deformed, and the intensity of the second infrared signal when the liquid lens is deformed can be pre-detected and stored. In this way, it is possible to determine whether the infrared parameter satisfies the corresponding first preset relationship based on the infrared parameter detected by the liquid camera detection device (i.e., the intensity of the second infrared signal), thereby accurately determining whether the liquid lens is leaking.

[0054] It can be understood that in the above two possible implementation methods, when the liquid camera detection device detects the infrared parameters of the liquid lens, compared with when the liquid lens is not damaged, when the liquid lens is damaged, the curvature of the liquid lens changes, the emission angle of the first infrared signal emitted by the infrared transmitter changes, and the signal intensity transmitted through the liquid lens also changes, and then, the intensity of the second infrared signal received by the infrared receiver changes. The infrared parameters can be determined by the received second infrared signal, and by comparing the infrared parameters with the corresponding first preset relationship, it can be confirmed whether the liquid lens is leaking.

[0055] The liquid camera detection device provided in the embodiment of the present application can detect the infrared parameters of the liquid lens (i.e., the first ratio of the first infrared signal to the second infrared signal) through an infrared transmitter and an infrared receiver. Since the corresponding infrared parameters are different when the liquid lens is leaking or not leaking, it is possible to quickly and accurately determine whether the liquid lens is leaking based on the detected infrared parameters. Therefore, the embodiment of the present application can avoid damage to the liquid camera and the corresponding circuit board caused by leakage of the liquid lens during the use of the liquid camera.

[0056] Optionally, in the embodiment of the present application, combined with Figure 1 ,like Figure 2As shown, the above-mentioned liquid camera includes a housing 400 and a driving unit 420, and the liquid lens is arranged in the housing 400; the clamp 500 includes: a clamping part, used to clamp the housing 400; a fixing part 530, the fixing part 530 is arranged in the clamping part, and the infrared transmitter 510 and the infrared receiver 520 are both arranged in the fixing part 530; a power supply port, used to connect the first interface of the liquid camera.

[0057] When the power supply port is connected to the first interface, the liquid camera detection device can supply power to the first interface through the power supply port, so as to drive the liquid lens to deform through the driving unit 420.

[0058] It can be understood that the first interface of the liquid camera is electrically connected to the driving unit 420 .

[0059] In a possible example, the clamping portion may include a boss disposed on the inner wall of the clamp 500 , and the boss is used to clamp and fix the housing 400 so that the clamp 500 clamps the liquid camera.

[0060] In a possible example, the clamping portion may include a groove provided on the inner wall of the clamp 500 , and the groove is used to clamp and fix the housing 400 so that the clamp 500 clamps the liquid camera.

[0061] In a possible example, the clamping portion may include a bolt, a blind hole is provided on the outer wall of the shell, and a through hole is provided on the clamp corresponding to the blind hole. The bolt can be inserted into the blind hole through the through hole to fix the shell in the clamp so that the clamp clamps the liquid camera.

[0062] Exemplarily, the clamp includes a first sub-clamp and a second sub-clamp, and a connecting piece is provided on the outer periphery of the outer shell. When the liquid camera is clamped in the clamp, the connecting piece is located between the first sub-clamp and the second sub-clamp 500, so that the first sub-clamp and the second sub-clamp clamp the connecting piece, thereby clamping the liquid camera.

[0063] Exemplarily, the power supply port may be disposed on a side wall of the fixture 500 .

[0064] Exemplarily, the fixing portion 530 may be disposed on a side wall of the fixture 500, and the infrared transmitter 510 and the infrared receiver 520 are disposed on the fixing portion 530. That is, the infrared transmitter 510 and the infrared receiver 520 may be disposed on a side wall of the fixture 500 through the fixing portion 530.

[0065] Exemplarily, the positions of the infrared transmitter 510 and the infrared receiver 520 on the fixing portion 530 correspond to the edge of the liquid lens. It can be understood that the degree of deformation of the edge of the liquid lens is greater than the degree of deformation away from the inner wall of the fixture 500 (i.e., the center of the liquid lens), so that when leakage occurs, the liquid lens leakage can be quickly and accurately determined.

[0066] Exemplarily, the drive unit 420 may be an electric drive unit, a mechanical drive unit, a manual drive unit, or the like.

[0067] For example, Figure 2 As shown, the driving unit 420 of the liquid camera includes: a driving rod 423, an extrusion member 421 and a support member 422. The driving rod 423 is connected to the extrusion member 421, and the support member 422 is arranged opposite to the extrusion member 421. Along the optical axis direction of the liquid lens, the support member 422, the liquid lens, and the extrusion member 421 are arranged in sequence. The driving rod 423 is arranged on the side of the extrusion member 421 away from the liquid lens.

[0068] For example, refer to Figure 2 There can be two driving rods 423 on each extrusion piece 421.

[0069] For example, Figure 3 As shown, there are two extrusion members 421, which are arranged opposite to each other, that is, evenly distributed along the inner wall of the housing 400. In this way, when the driving unit 420 is working, the extrusion members 421 can apply a uniform extrusion force to the liquid lens.

[0070] It can be understood that each extrusion member 421 is connected to a driving rod 423, and each extrusion member 421 corresponds to a supporting member 422. A first spacing is set between the extrusion member 421 and the supporting member 422. When the driving rod 423 is driven by a driving force, the extrusion member 421 can move, and the supporting member 422 remains fixed. With the movement of the extrusion member 421, the distance of the first spacing can be reduced or increased to adjust the focal length of the liquid lens.

[0071] When the extrusion piece 421 squeezes the liquid lens, the deformation of the liquid lens film close to the extrusion piece 421 is smaller than the deformation of the liquid lens film far away from the extrusion piece 421. In order to detect real and objective infrared parameters, in the embodiment of the present application, the infrared transmitter 510 and the infrared receiver 520 are arranged far away from the extrusion piece 421.

[0072] Exemplarily, when the liquid camera is clamped in the fixture 500, that is, when the housing 400 of the liquid camera is clamped in the fixture 500 by the clamping part, in the orthographic projection of the fixture 500 and the liquid camera, the infrared transmitter 510 and the infrared receiver 520 are staggered with the extrusion piece 421, and the infrared transmitter 510 and the infrared receiver 520 are arranged away from the extrusion piece 421. For example, in the orthographic projection, the infrared transmitter 510 and the infrared receiver 520 are located at the center between two adjacent extrusion pieces 421 and close to the edge of the liquid lens.

[0073] Optionally, in the embodiment of the present application, Figure 4 As shown, when the liquid camera is clamped in the fixture 500, the infrared transmitter 510 and the infrared receiver 520 are respectively located on both sides of the liquid lens;

[0074] The second infrared signal is a signal obtained after the first infrared signal is transmitted through the liquid lens.

[0075] Exemplarily, the liquid camera may be disposed at a preset position of the fixture 500 , and the preset position may be a fixed position.

[0076] It can be understood that the infrared transmitter 510 and the infrared receiver 520 are fixed on the inner wall of the fixture 500, that is, the positions of the infrared transmitter 510 and the infrared receiver 520 on the inner wall of the fixture 500 are fixed. When the liquid camera is set in the fixture 500, when the liquid lens is not leaking, the distance a between the liquid lens and the infrared transmitter 510 is the same as the distance b between the liquid lens and the infrared receiver 520; when the liquid lens is leaking, the thickness of the liquid lens changes, then the distance a between the liquid lens and the infrared transmitter 510 will change, and the distance b between the liquid lens and the infrared receiver 520 will also change. Therefore, the first infrared signal emitted by the infrared transmitter 510 and the second infrared signal after being transmitted by the liquid lens also change accordingly, and then the infrared parameters change.

[0077] In this way, whether the liquid lens is leaking can be determined based on the infrared parameters detected by the liquid camera detection device.

[0078] For example, refer to Figure 4 As shown, the infrared transmitter 510 is located below the liquid lens, and the infrared receiver 520 is located above the liquid lens.

[0079] Exemplarily, the infrared transmitter may also be located above the liquid lens, and the infrared receiver may also be located below the liquid lens.

[0080] Optionally, in the embodiment of the present application, Figure 1 As shown, when the liquid camera is clamped in the clamp 500, the infrared transmitter 510 and the infrared receiver 520 are both arranged on the same side of the liquid camera;

[0081] The second infrared signal is: a signal obtained after the first infrared signal is reflected by the liquid lens.

[0082] Exemplarily, the liquid camera may be disposed at a preset position of the fixture 500 , and the preset position may be a fixed position.

[0083] It can be understood that the infrared transmitter 510 and the infrared receiver 520 are fixed on the inner wall of the fixture 500, that is, the positions of the infrared transmitter 510 and the infrared receiver 520 on the inner wall of the fixture 500 are fixed.

[0084] When the liquid camera is placed in the fixture 500, when the liquid lens is not leaking, the distance a between the liquid lens and the infrared transmitter 510 and the distance b between the liquid lens and the infrared receiver 520 are; when the liquid lens is leaking, the thickness of the liquid lens changes, and the distance a between the liquid lens and the infrared transmitter 510 will change, and the distance b between the liquid lens and the infrared receiver 520 will also change. Therefore, the first infrared signal emitted by the infrared transmitter 510 and the second infrared signal reflected by the liquid lens also change accordingly, that is, the infrared parameters change. In this way, it is possible to determine whether the liquid lens is leaking based on the infrared parameters detected by the liquid camera detection device.

[0085] Alternatively, when the liquid camera is placed in the fixture 500, compared to when the liquid lens is not damaged, when the liquid lens is damaged, the curvature of the liquid lens film changes, and the reflection and / or refraction angle of the first infrared signal emitted by the infrared transmitter 510 on the liquid lens changes, and then the light intensity of the second infrared signal reflected back by the infrared receiver 520 changes, that is, the infrared parameters change. In this way, it can be determined whether the liquid lens is leaking based on the infrared parameters detected by the liquid camera detection device.

[0086] For example, Figure 5 and Figure 6 As shown, due to Figure 6 The liquid camera in the Figure 5 and Figure 6 It can be seen that Figure 5 The curvature of the liquid lens film 411 is Figure 6 The curvature of the liquid lens film 411 is different. Figure 5 The second infrared signal received by the corresponding infrared receiver 520 must be Figure 6 If the second infrared signals received by the corresponding infrared receiver 520 are different, then the infrared parameters detected by the liquid camera detection device are different. It can be understood that Figure 5 The infrared parameters detected by the corresponding liquid camera detection device will satisfy the corresponding first preset relationship; Figure 6 The infrared parameters detected by the corresponding liquid camera detection device will not satisfy the corresponding preset relationship. In this way, it is possible to quickly and accurately determine whether the liquid lens is leaking based on the infrared parameters detected by the liquid camera detection device.

[0087] For example, Figure 1As shown, the infrared transmitter 510 and the infrared receiver 520 may both be disposed below the liquid lens.

[0088] Exemplarily, the infrared transmitter 510 and the infrared receiver 520 may also be disposed above the liquid lens.

[0089] The present application embodiment also provides an electronic device 200, such as Figure 7 As shown, the electronic device 200 includes the liquid camera detection device 100 provided in any one of the above embodiments.

[0090] The present application embodiment also provides an electronic device 300, such as Figure 8 As shown, the electronic device 300 includes a processing unit 302 and a power supply unit 301 connected to the processing unit.

[0091] In the scenario of producing the above-mentioned liquid camera, the power supply unit can be electrically connected to the power supply port of the liquid camera detection device to supply power to the driving unit, infrared transmitter, and infrared receiver of the liquid camera. Thus, the infrared parameters of the liquid lens of the liquid camera when undeformed and deformed can be detected, and the detected infrared parameters can be sent to the processing unit. Through the processing unit, the received infrared parameters are compared with the corresponding first preset relationship to accurately determine whether the liquid lens is leaking, thereby improving the quality of quality inspection of the liquid camera during the production stage and avoiding using damaged and leaking liquid cameras as normal products for other electronic devices.

[0092] Specifically, the electronic device 300 can detect the infrared parameters of the liquid lens when it is not deformed through an infrared transmitter and an infrared receiver, and send the detected infrared parameters to the processing unit. The processing unit compares the received infrared parameters with the corresponding first preset relationship. If the received infrared parameters meet the corresponding first preset relationship, it is determined that the liquid lens is not leaking; otherwise, it is leaking.

[0093] The electronic device 300 can also detect infrared parameters of the liquid lens when it is deformed through an infrared transmitter and an infrared receiver, and send the detected infrared parameters to a processing unit. The processing unit compares the received infrared parameters with the corresponding first preset relationship. If the received infrared parameters meet the corresponding first preset relationship, it is determined that the liquid lens is not leaking; otherwise, it is leaking.

[0094] Optionally, in the embodiment of the present application, the electronic device 300 further includes a display unit 303; the display unit is used to display a first prompt message or a second prompt message, the first prompt message is used to prompt that the liquid lens is leaking, and the second prompt message is used to prompt that the liquid lens is not leaking.

[0095] Exemplarily, the display unit may be electrically connected to the power supply unit via the processing unit, and the display unit is used to display the processing result of the processing unit.

[0096] like Fig. 9 As shown, the embodiment of the present application also provides a liquid camera leakage detection method, which can be applied to the liquid camera detection device provided in any of the above embodiments. The method provided in the embodiment of the present application is described below with the liquid camera detection device as the execution subject. The method includes step 101 and step 102.

[0097] Step 101: When the liquid camera is placed in a fixture of a liquid camera detection device and a start command of the liquid camera is detected, the liquid lens of the liquid camera is detected by an infrared transmitter and an infrared receiver of the liquid camera detection device to obtain a first infrared parameter.

[0098] In the embodiment of the present application, the start instruction may be: a shooting instruction, such as a photo taking instruction or a video recording instruction.

[0099] Step 102: when the first infrared parameter satisfies the first preset relationship, displaying the first prompt information;

[0100] In step 101, “detecting the liquid lens of the liquid camera by using the infrared transmitter and the infrared receiver of the liquid camera detection device” includes:

[0101] Step 101a: The infrared transmitter transmits a first infrared signal.

[0102] Step 101b: The infrared receiver receives a second infrared signal, where the second infrared signal is a signal of the first infrared signal after being reflected or transmitted by the liquid lens.

[0103] Wherein, the first infrared parameter is a first ratio of the first infrared signal to the second infrared signal;

[0104] The first prompt information is used to prompt that the liquid lens is leaking.

[0105] In the embodiment of the present application, the first preset relationship is: a preset relationship between numerical values ​​corresponding to infrared parameters of the liquid lens when the liquid lens is not deformed.

[0106] In the embodiment of the present application, when the above-mentioned start-up instruction is detected, the liquid camera can be in a state where no deformation occurs. Figure 6 As shown, Figure 6A schematic diagram of a liquid camera in a state where no deformation occurs is shown. In this case, power can be supplied to the infrared transmitter and the infrared receiver unit by a power supply unit of an external device, the infrared transmitter can transmit a first infrared signal to the liquid lens, and the infrared receiver can receive a second infrared signal, thereby detecting a first infrared parameter (e.g., a first ratio of the first infrared signal to the second infrared signal, or an intensity value of the second infrared signal). Furthermore, the first infrared parameter can be compared with the corresponding first preset relationship to determine whether the first infrared parameter satisfies the first preset relationship.

[0107] In the embodiment of the present application, the first prompt information can be displayed in a highlighted manner, thereby making it convenient for users to view.

[0108] Exemplarily, the first prompt information includes at least one of the following: text prompt information, logo prompt information. Taking text prompt information as an example, the first prompt information may be: the liquid camera is leaking.

[0109] Optionally, in the embodiment of the present application, when the liquid camera is clamped in the fixture, the infrared transmitter and the infrared receiver are respectively located on both sides of the liquid lens;

[0110] The second infrared signal is a signal obtained after the first infrared signal is transmitted through the liquid lens.

[0111] Optionally, in an embodiment of the present application, when the liquid camera is clamped in the fixture, the infrared transmitter and the infrared receiver are both arranged on the same side of the liquid lens;

[0112] The second infrared signal is a signal obtained after the first infrared signal is reflected by the liquid lens.

[0113] Optionally, in an embodiment of the present application, the above method also includes steps 103 to 105.

[0114] Step 103: When the first infrared parameter does not satisfy the first preset relationship, controlling the driving unit of the liquid camera to drive the liquid lens to deform;

[0115] Step 104: Detect the liquid lens of the liquid camera through the infrared transmitter and the infrared receiver of the liquid camera detection device to obtain a second infrared parameter;

[0116] Step 105: When the second infrared parameter satisfies the first preset relationship, display a second prompt message;

[0117] The second infrared parameter is: a second ratio of the first infrared signal emitted by the infrared transmitter to the second infrared signal received by the infrared receiver after the liquid camera is deformed;

[0118] The second prompt information is used to prompt that the liquid lens is leaking.

[0119] It can be understood that after the driving unit controlling the liquid camera drives the liquid lens to deform, the above steps 101a and 101b can be repeated to obtain the second infrared parameter.

[0120] It is understandable that the liquid lens does not leak when it is not deformed. However, when it is deformed, the liquid lens film may be damaged due to pressure during use, thereby leaking. In order to ensure that the liquid lens is in a state of not leaking whether it is deformed or not, it is also necessary to detect whether the liquid lens is leaking when the liquid lens is in a deformed state.

[0121] It should be noted that the first preset relationship in the embodiment of the present application is: a preset relationship between numerical values ​​corresponding to infrared parameters when the liquid lens is deformed.

[0122] In the embodiment of the present application, if the first infrared parameter satisfies the corresponding first preset relationship (i.e., the preset relationship of the numerical value corresponding to the infrared parameter when the liquid lens is not deformed), it means that when the liquid lens is in a state where no deformation occurs, the liquid lens is not leaking. In this case, the liquid lens can be driven to deform by the driving unit.

[0123] After the liquid lens is deformed, the liquid lens can be further detected through the infrared transmitter and the infrared receiver to obtain a second infrared parameter. If the second infrared parameter satisfies the corresponding first preset relationship (i.e., the preset relationship of the numerical value corresponding to the infrared parameter when the liquid lens is deformed), it means that the liquid lens is not leaking, and the liquid lens is a good product (i.e., a normal product). If the second infrared parameter does not satisfy the corresponding first preset relationship, it means that the liquid lens is leaking, and a second prompt message can be displayed. The specific scheme of the second prompt message can refer to the above-mentioned first prompt message, which will not be repeated here.

[0124] For example, see Figure 5 and Figure 6 As shown, due to Figure 6 The liquid camera in the Figure 5 and Figure 6 It can be seen that Figure 5 The curvature of the liquid lens film 411 is Figure 6 The curvature of the liquid lens film 411 is different. Figure 5 The second infrared parameter detected by the corresponding liquid camera detection device must be Figure 6 The second infrared parameters detected by the corresponding liquid camera detection device are different. It can be understood that Figure 5 The second infrared parameter detected by the corresponding liquid camera detection device will satisfy the corresponding first preset relationship; Figure 6The second infrared parameter detected by the corresponding liquid camera detection device will not satisfy the corresponding first preset relationship.

[0125] Optionally, in the embodiment of the present application, the above method also includes: step 106.

[0126] Step 106: When the second infrared parameter does not satisfy the first preset relationship, display a third prompt message;

[0127] Among them, the third prompt information is used to prompt the liquid camera

[0128] It can be understood that the first preset relationship in the embodiment of the present application is: a preset relationship between numerical values ​​corresponding to infrared parameters when the liquid lens is deformed.

[0129] It should be noted that if the first infrared parameter satisfies the corresponding first preset relationship, the third prompt information may also be displayed.

[0130] The specific scheme of the third prompt information can refer to the above-mentioned first prompt information, which will not be repeated here.

[0131] It can be understood that if the second infrared parameter satisfies the corresponding first preset relationship, it means that the liquid lens is not leaking and the liquid camera is a good product (i.e., a normal product). Therefore, the third prompt information can be displayed to remind the inspection personnel that the inspected liquid camera is a normal product.

[0132] Optionally, in the embodiment of the present application, the liquid camera detection device includes an infrared detection unit, and the infrared detection unit includes the above-mentioned infrared transmitter and infrared receiver. If there are multiple infrared detection units, the first infrared parameter and the second infrared parameter are both: the average value of the infrared parameters obtained by detecting the liquid camera through multiple infrared detection units.

[0133] Thus, the influence of different damage positions on the detection results of the infrared detection unit is avoided, and the accuracy of the detection results is improved.

[0134] Optionally, in the embodiment of the present application, the “controlling the driving unit of the liquid camera to drive the liquid lens to deform” in the above step 103 includes step 103a.

[0135] Step 103a: Control the driving unit of the liquid camera to drive the liquid lens to generate a first deformation amount.

[0136] The first deformation amount is greater than or equal to the first preset deformation amount, and less than or equal to the second preset deformation amount. For example, the first deformation amount is the deformation amount corresponding to when the liquid lens reaches 2 times the focal length (or other focal lengths).

[0137] It should be noted that the second preset deformation amount is the deformation amount corresponding to the maximum deformation of the liquid lens, and the first preset deformation amount is the deformation amount corresponding to the minimum deformation of the liquid lens.

[0138] It can be understood that the first preset deformation amount is smaller than the second preset deformation amount.

[0139] Exemplarily, the first deformation amount may be slightly smaller than the second preset deformation amount, so as to prevent the first deformation amount from being too large and causing damage to the liquid lens, and to detect whether the liquid lens is leaking when working normally.

[0140] Optionally, in the embodiment of the present application, before “detecting the liquid lens of the liquid camera by using the infrared transmitter and the infrared receiver of the liquid camera detection device” in step 101, the method further includes:

[0141] Step A: determine whether the liquid lens is deformed.

[0142] Step B: If deformation occurs, control the liquid lens to be in a state where no deformation occurs.

[0143] Step C: If no deformation occurs, execute step 101.

[0144] In the embodiment of the present application, whether the liquid lens is deformed can be determined by the focal length of the liquid lens.

[0145] In the embodiment of the present application, the liquid lens is controlled to be in a state where no deformation occurs, that is, the liquid lens is controlled to be in an initial state.

[0146] Exemplarily, if deformation occurs, the liquid lens can be controlled to be in a non-deformed state by a driving unit of the liquid camera.

[0147] The liquid camera leakage detection method provided in the embodiment of the present application is that when the liquid camera is set in the fixture of the liquid camera detection device, and when the start command of the liquid camera is detected, the liquid lens of the liquid camera is detected through the infrared transmitter and infrared receiver of the liquid camera detection device, and when the first infrared parameter satisfies the first preset relationship, a first prompt message is displayed; the first prompt message is used to prompt that the liquid lens is leaking. Therefore, the user (i.e., the detection personnel) can conveniently confirm whether the liquid lens of the liquid camera is leaking through the first prompt message, improve the accuracy of the quality inspection of the non-leaking liquid lens in the production process of the liquid camera, and avoid using the liquid camera when the liquid lens is leaking, which causes damage to the liquid camera and the corresponding circuit board.

[0148] It should be noted that the liquid camera leakage detection method provided in the embodiment of the present application can be executed by a liquid camera detection device, or a control module in the liquid camera detection device for executing the liquid camera leakage detection method. In the embodiment of the present application, the method of executing liquid camera leakage detection by a liquid camera leakage detection device is taken as an example to illustrate the liquid camera leakage detection device provided in the embodiment of the present application.
