[0022] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings.
[0023] This application proposes a fixture that can dynamically test the compressive performance. Please refer to Figure 1 and Figure 2 , including a sensor 12, a knob 13, a screw 10, a base 11, a first clamping plate 14 and a second clamping plate 15. The first clamping plate 14 and the second clamping plate 15 are arranged in parallel, the first clamping plate 14 is fixed above the second clamping plate 15 at an interval, a product placement area 20 is arranged between the first clamping plate 14 and the second clamping plate 15, the camera module is placed in the product placement area 20 for testing, the first clamping plate 14 is provided with a lens hole 21, and the lens of the camera module is aligned with the lens hole 21 to shoot outward. The second clamping plate 15 and the base 11 are both provided with matching mounting holes with internal threads, the sensor 12 is arranged at one end of the screw 10, the knob 13 is arranged at the other end of the screw 10, and the side of the screw 10 is provided with an external thread matching the mounting hole. The screw 10 is rotatably and telescopically arranged in the mounting hole, and the end of the screw 10 provided with the sensor 12 is close to the first clamping plate 14, and the base 11 is sleeved on the screw 10 and abuts against the side of the second clamping plate 15 away from the first clamping plate 14. The camera module to be tested is fixed in the product placement area 20, and the changes in the resolution and tolerance of the camera module can be monitored in real time within a certain range, so that the test data is more comprehensive, and the device has a simple structure and low cost, which can save the cost of purchasing large-scale testing equipment, thereby reducing the manufacturing cost.
[0024] See also Figure 1, the fixture of the present application also includes four adjustment columns 23, which serve to fix the first clamping plate 14 and the second clamping plate 15. The first clamping plate 14 is fixed to the second clamping plate 15 by four adjustment columns 23, and the four adjustment columns 23 are respectively arranged at the edges of the four sides of the first clamping plate 14, and the space enclosed by the four adjustment columns 23 is used to place the product to be tested. Specifically, one end of the adjustment column 23 is fixed to the first clamping plate 14, and the other end is provided with an external thread on the side, and the second clamping plate 15 is provided with four screw holes with internal threads, and the adjustment column 23 is rotated through the screw holes to adjust the distance between the first clamping plate 14 and the second clamping plate 15. Furthermore, a gasket is provided on one side of the sensor 12 and the test product. When the knob 13 applies pressure to the camera module through the screw 10, the gasket can protect the sensor 12 from contacting the camera module to be tested. In addition, the pressure applied to the camera module can be transmitted to the sensor 12 for sensing through the gasket. In addition, please refer to Figure 2 The protective layer 25 is arranged at the other end of the screw 10 away from the knob 13. The protective layer 25 is made of soft material. When the knob 13 and the screw 10 jointly apply pressure to the camera module, the protective layer 25 increases the contact area with the camera module and reduces the pressure. It can protect the appearance of the camera module to a certain extent and prevent the appearance of the camera module from being damaged to a greater extent.
[0025] See also Figure 1 The jig of the present application also includes a fixed bracket, which includes two support plates 22, which are respectively arranged on both sides of the second clamping plate 15. When using the jig, the tester does not need to operate it by hand. Specifically, the length of the support plate 22 is greater than the total length of the screw 10 and the knob 13 assembled, so that the support plate 22 can fully support the entire jig to prevent the knob 13 from touching the ground, and the staff does not need to pick up the jig to adjust the knob 13, reducing the interference of external forces such as the staff on the resolution of the camera module to be tested, thereby obtaining more accurate test data.
[0026] For further information, see Figure 2 The second clamping plate 15 has a groove 24 on one side of the first clamping plate 14 that matches the protective layer 25. The depth of the groove 24 is consistent with the height of the protective layer 25, which can be adjusted by the knob 13. The protective layer 25 is embedded in the groove 24, so that the height range of the testable camera module is larger to accommodate more camera modules, so that the universality of the fixture is stronger, and a limit is formed with the mounting hole to prevent the screw 10 and the sensor 12 from falling from the mounting hole. Furthermore, the knob 13 is fixedly connected to the screw 10, and the diameter of the knob 13 is larger than the diameter of the mounting hole, thereby forming a limit.
[0027] Preferably, the sensor 12 is a pressure sensor.
[0028] In addition, the fixture of the present application also includes an analysis terminal, and the sensor 12 is electrically connected to the analysis terminal. The analysis terminal can detect in real time the pressure applied by the knob 13 to the camera module and the corresponding changes in the resolution of the camera module to obtain comprehensive data and gain sufficient understanding of its own products.
[0029] When the camera module is placed in the product placement area 20, the camera module is connected to the analysis terminal. The staff can adjust the knob 13 so that the end of the screw 10 provided with the sensor 12 gradually applies a changing pressure to the camera module, and the sensor 12 can detect the pressure applied to the camera module in real time, and the real-time data of the pressure is transmitted to the analysis terminal. The pressure applied to the camera module corresponds to the resolution of the camera module in real time, so that the tester can dynamically observe the corresponding changes in the force and resolution of the camera module, and the data is more comprehensive.
[0030] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
