Description

Technical Field

[0001] This utility model relates to the field of mobile phone camera production and testing technology, and more specifically, to a sealing test structure for mobile phone cameras. Background Technology

[0002] With the continuous development of smartphones, people have higher and higher requirements for the performance of mobile phone cameras. Among them, the sealing of the camera is one of the important factors affecting its performance. If the camera is not sealed well, moisture, dust and other impurities can easily enter the camera, causing problems such as blurry images and spots, thereby affecting the overall quality of the mobile phone and the user experience.

[0003] While there are many sealing tests available for mobile phones, there are no dedicated devices or instruments for testing the sealing and waterproofing of rear cameras. Currently, manual testing is the most common method, which has serious issues with missed tests, making it impossible to identify defective products.

[0004] A search revealed that Chinese patent CN217901151U discloses a sealing test device for a mobile phone rear camera. This device controls a lifting device to press down a flexible sealing device, causing the lower end of the silicone block of the flexible sealing device to cover the rear camera of the mobile phone and form a sealed cavity with the outer wall of the mobile phone. Then, a vacuum pump is controlled to extract air from the sealed cavity to create a vacuum in the silicone block. If the cavity is well sealed, the internal air pressure value after vacuuming is a stable value. If there is a problem with the sealing of the cavity, the internal air pressure value will change in real time. This is used to judge the sealing effect of the product. The structure is simple and the design is reasonable. It replaces manual inspection, has high testing efficiency and accuracy, and can effectively screen out defective products, avoiding the risk of defective products flowing out.

[0005] However, in actual use, due to the large differences in size and camera position of different mobile phone models, the fixed four corners method is difficult to be compatible with multiple models, and the limit blocks need to be replaced frequently, which affects the testing efficiency. Moreover, with only the four corners as the limit, there may be slight shaking on the back of the phone, which will cause the sealing cavity to shift when the flexible sealing device is pressed down, affecting the testing accuracy.

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a sealing test structure for mobile phone cameras to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A sealing test structure for a mobile phone camera includes a test frame, a fixing seat fixedly disposed on the top of the test frame, a support frame fixedly disposed on the top of the test frame, and a positioning mechanism disposed inside the test frame.

[0009] The positioning mechanism includes multiple first electric telescopic rods fixedly installed inside the test frame, with a movable plate fixedly installed at the output end of each first electric telescopic rod, and multiple guide grooves opened on the surface of the test frame;

[0010] The surface of the movable plate is provided with a sliding groove, and a T-shaped internal thread block is slidably arranged inside the sliding groove. A small stepper motor is fixedly installed on one side of the movable plate, and a screw is fixedly installed at the output end of the small stepper motor. The screw is threadedly connected to the T-shaped internal thread block. A positioning plate is fixedly installed on one side of the T-shaped internal thread block.

[0011] The movable plate is slidably connected to the guide groove. A fixing groove is provided on the surface of the movable plate. An L-shaped slider is slidably arranged inside the fixing groove. One end of the L-shaped slider is connected to the surface of the positioning plate.

[0012] By adopting the above technical solution: the positioning mechanism with multi-directional adjustment can achieve precise fixation of mobile phone camera, adapt to different product specifications, and the rubber layer design avoids damage to the camera surface during the test, while enhancing friction to ensure positioning stability.

[0017] An air pump is installed through one side of the sealing cover, a fixing strip is rotatably installed on the surface of the connecting frame, the fixing strip is connected to the connecting frame by bolts, and a controller is fixedly installed on one side of the test frame.

[0018] By adopting the above technical solution: the combination design of the sealing cover and the sealing layer ensures the airtightness of the test environment and improves the accuracy of the test results. Moreover, the pressure sensor monitors the air pressure changes in real time, providing a quantitative basis for the judgment of the sealing performance and reducing human error. Furthermore, the detachable connection of bolts and fixing strips allows for the quick replacement of sealing covers of different specifications, improving the versatility of the equipment.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] The embodiments disclosed in this application are as follows: Figure 1-5 The mobile phone camera sealing test structure shown includes a test frame 1, a fixing seat 2 fixedly installed on the top of the test frame 1, a support frame 3 fixedly installed on the top of the test frame 1, and a positioning mechanism installed inside the test frame 1.

[0030] The positioning mechanism includes multiple first electric telescopic rods 4 fixedly installed inside the test frame 1. The output end of the first electric telescopic rod 4 is fixedly provided with a movable plate 5. Multiple guide grooves 6 are opened on the surface of the test frame 1.

[0031] The surface of the movable plate 5 is provided with a sliding groove, and a T-shaped internal thread block 7 is slidably arranged inside the sliding groove. A small stepper motor 8 is fixedly installed on one side of the movable plate 5. A screw 9 is fixedly installed at the output end of the small stepper motor 8. The screw 9 is threadedly connected to the T-shaped internal thread block 7. A positioning plate 10 is fixedly installed on one side of the T-shaped internal thread block 7. A rubber layer 11 is fixedly installed on one side of both the movable plate 5 and the positioning plate 10.

[0032] The movable plate 5 is slidably connected to the guide groove 6. A fixing groove is provided on the surface of the movable plate 5. An L-shaped slider 12 is slidably arranged inside the fixing groove. One end of the L-shaped slider 12 is connected to the surface of the positioning plate 10.

[0033] The controller 26 issues a command to activate multiple first electric telescopic rods 4 inside the test frame 1. The output end of the first electric telescopic rod 4 extends, causing the movable plate 5 to slide along the guide groove 6, thereby causing the movable plate 5 to move closer to both sides of the mobile phone camera until the rubber layer 11 on one side of the movable plate 5 contacts both sides of the mobile phone camera for initial fixation.

[0034] Next, the small stepper motor 8 starts, and its output end drives the screw 9 to rotate. Since the screw 9 is threadedly connected to the T-shaped internal thread block 7, the T-shaped internal thread block 7 will move along the direction of the screw 9 in the sliding groove on the surface of the movable plate 5, thereby driving the positioning plate 10 to move. The rubber layer 11 on one side of the positioning plate 10 contacts the mobile phone camera and clamps and fixes the other side of the mobile phone camera. The rubber layer 11 plays the role of anti-slip and protecting the mobile phone camera. At the same time, the L-shaped slider 12 slides in the fixing groove of the movable plate 5, assisting the positioning plate 10 to move smoothly and ensuring the positioning effect.

[0035] Reference Figure 2-4 As shown, a second electric telescopic rod 13 is fixedly installed inside the support frame 3, an adjustment block 14 is fixedly installed at the output end of the second electric telescopic rod 13, an adjustment frame 15 is fixedly installed on one side of the adjustment block 14, and the adjustment block 14 is slidably connected to the support frame 3.

[0036] The adjustment frame 15 is equipped with a detection mechanism, which includes a stepper motor 16 fixedly installed on one side of the adjustment frame 15. A ball screw 17 is fixedly installed at the output end of the stepper motor 16. A moving block 18 is installed outside the ball screw 17. The moving block 18 is slidably connected to the adjustment frame 15.

[0037] The second electric telescopic rod 13 inside the support frame 3 is started under the control of the controller 26. Its output end drives the adjusting block 14 to slide along the support frame 3. The adjusting block 14 drives the adjusting frame 15 to move up and down, adjusting the adjusting frame 15 to a suitable height so that the subsequent sealing cover 21 can be in a suitable relative position with the mobile phone camera.

[0038] The stepper motor 16 is started, and its output drives the ball screw 17 to rotate. The moving block 18 slides along the adjustment frame 15 under the action of the ball screw 17, thereby adjusting the horizontal position of the connecting frame 19, the connecting block 20, and the sealing cover 21, so that the sealing cover 21 can be accurately positioned directly above the mobile phone camera.

[0039] Reference Figure 1 , 4As shown in Figure 5, a connecting frame 19 is fixedly provided at the bottom of the movable block 18, a connecting block 20 is inserted into the inside of the connecting frame 19, a sealing cover 21 is fixedly provided at the bottom of the connecting block 20, a sealing layer 22 is fixedly provided at the bottom of the sealing cover 21, and a pressure sensor 23 is fixedly provided inside the sealing cover 21.

[0040] An air pump 24 is provided through one side of the sealing cover 21, a fixing strip 25 is rotatably provided on the surface of the connecting frame 19, and the fixing strip 25 is connected to the connecting frame 19 by bolts. A controller 26 is fixedly provided on one side of the test frame 1.

[0041] The second electric telescopic rod 13 is activated again, causing the connecting frame 19 to move downwards. The connecting block 20 causes the sealing cover 21 to descend. The sealing layer 22 at the bottom of the sealing cover 21 fits tightly against the periphery of the mobile phone camera, forming a sealed space. Then, the air pump 24 is activated to evacuate the sealed space inside the sealing cover 21, changing the air pressure inside the sealed space. The pressure sensor 23 inside the sealing cover 21 detects the changes in air pressure inside the sealed space in real time and transmits the detection data to the controller 26. The controller 26 analyzes and judges the data transmitted by the pressure sensor 23. If the air pressure inside the sealed space remains stable within the set time, it indicates that the mobile phone camera is well sealed. If there is a significant change in air pressure, it indicates that there is a sealing problem with the mobile phone camera.

[0042] When the sealing cover 21 needs to be replaced, first unscrew the bolts between the fixing strip 25 and the connecting frame 19, then rotate the fixing strip 25 to release the limit on the connecting block 20, thereby pulling the connecting block 20 out of the connecting frame 19, thereby driving the sealing cover 21 out for replacement.

[0043] Working principle of this utility model:

[0044] This utility model is a sealing test structure for mobile phone cameras. When using the device, the mobile phone camera to be tested is placed on the fixed seat 2 at the top of the test frame 1 for positioning and fixing. The controller 26, the first electric telescopic rod 4, the small stepper motor 8, the second electric telescopic rod 13, the stepper motor 16 and the air pump 24 are all connected to an external power source.

[0045] Then the controller 26 issues a command to activate multiple first electric telescopic rods 4 inside the test frame 1. The output end of the first electric telescopic rod 4 extends, causing the movable plate 5 to slide along the guide groove 6, thereby causing the movable plate 5 to move closer to both sides of the mobile phone camera until the rubber layer 11 on one side of the movable plate 5 contacts both sides of the mobile phone camera for initial fixation.

[0046] Next, the small stepper motor 8 starts, and its output end drives the screw 9 to rotate. Since the screw 9 is threadedly connected to the T-shaped internal thread block 7, the T-shaped internal thread block 7 will move along the direction of the screw 9 in the sliding groove on the surface of the movable plate 5, thereby driving the positioning plate 10 to move. The rubber layer 11 on one side of the positioning plate 10 contacts the mobile phone camera and clamps and fixes the other side of the mobile phone camera. The rubber layer 11 plays the role of anti-slip and protecting the mobile phone camera. At the same time, the L-shaped slider 12 slides in the fixing groove of the movable plate 5 to assist the positioning plate 10 to move smoothly and ensure the positioning effect.

[0047] Then, the second electric telescopic rod 13 inside the support frame 3 is started under the control of the controller 26. Its output end drives the adjustment block 14 to slide along the support frame 3. The adjustment block 14 drives the adjustment frame 15 to move up and down, adjusting the adjustment frame 15 to a suitable height so that the subsequent sealing cover 21 can be in a suitable relative position with the mobile phone camera.

[0048] The stepper motor 16 is started, and its output drives the ball screw 17 to rotate. The moving block 18 slides along the adjustment frame 15 under the action of the ball screw 17, thereby adjusting the horizontal position of the connecting frame 19, the connecting block 20, and the sealing cover 21 so that the sealing cover 21 can be accurately positioned directly above the mobile phone camera.

[0049] The second electric telescopic rod 13 is activated again, causing the connecting frame 19 to move downwards. The connecting block 20 causes the sealing cover 21 to descend. The sealing layer 22 at the bottom of the sealing cover 21 fits tightly against the periphery of the mobile phone camera, forming a sealed space. Then, the air pump 24 is activated to evacuate the sealed space inside the sealing cover 21, changing the air pressure inside the sealed space. The pressure sensor 23 inside the sealing cover 21 detects the changes in air pressure inside the sealed space in real time and transmits the detection data to the controller 26. The controller 26 analyzes and judges the data transmitted by the pressure sensor 23. If the air pressure inside the sealed space remains stable within the set time, it indicates that the mobile phone camera is well sealed. If there is a significant change in air pressure, it indicates that there is a sealing problem with the mobile phone camera.

[0050] After the test is completed, the air pump 24 stops working, the second electric telescopic rod 13 drives the adjustment frame 15 to rise, so that the sealing cover 21 is removed from the mobile phone camera. At the same time, the first electric telescopic rod 4 shortens, the movable plate 5 resets, and the positioning plate 10 resets under the control of the small stepper motor 8. The tested mobile phone camera is taken out and ready for the next test.

[0051] When the sealing cover 21 needs to be replaced, first unscrew the bolts between the fixing strip 25 and the connecting frame 19, then rotate the fixing strip 25 to release the limit on the connecting block 20, thereby pulling the connecting block 20 out of the connecting frame 19, thereby driving the sealing cover 21 out for replacement.

[0052] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
