[0025] The utility model provides a fingerprint module testing device. Figures 1 to 3 A specific embodiment of a fingerprint module testing device provided by the utility model.
[0026] like Figure 2 and Figure 3As shown, an embodiment of the utility model provides a fingerprint module testing device 100, including a shell 1, a testing device 2 and a switching device 3, wherein the shell 1 is provided with a mounting cavity, the testing device 2 is arranged in the mounting cavity, and the testing device 2 includes a grating 21, a guide structure 11 is provided in the mounting cavity, the switching device 3 includes a mounting seat 31 for fixing the grating 21, and the mounting seat 31 is movably arranged on the guide structure 11, one end of the shell 1 is provided with a mounting port 12 for placing a module to be tested, the mounting port 12 is communicated with the mounting cavity, and is located on the optical path of the light source 22 of the testing device 2, and the moving trajectory of the grating 21 intersects with the optical path of the light source 22.
[0027] In the utility model, a mounting cavity is provided in the shell 1, the test device 2 is provided in the mounting cavity, and the test device 2 includes a grating 21, a guide structure 11 is provided in the mounting cavity, the switching device 3 includes a mounting seat 31 for fixing the grating 21, and the mounting seat 31 is movably arranged on the guide structure 11. One end of the shell 1 is provided with a mounting port 12 for placing a module to be tested, the mounting port 12 is communicated with the mounting cavity, and is located on the optical path of the light source 22 of the test device 2, and the moving trajectory of the grating 21 intersects with the optical path of the light source 22. The operator places the fingerprint module to be tested on the mounting opening 12. When the grating 21 is not located on the optical path of the light source 22 of the testing device 2, the testing device 2 performs the first testing process on the module to be tested. After completing the above test, the mounting seat 31 moves on the guide structure 11, so that the grating 21 moves to the optical path of the light source 22. The light emitted by the light source 22 of the testing device 2 passes through the grating 21 to reach the module to be tested, thereby performing the second testing process on the module to be tested. Only by moving the grating 21, two testing processes of the module to be tested can be completed, which greatly improves the testing efficiency. In addition, since the module to be tested performs the second testing process immediately after completing the first testing process, it is avoided that some modules to be tested only complete one testing process.
[0028] It should be noted that the first test process includes bright and dark field, open and short circuit and current tests, and the second test process includes fingerprint imaging and center offset tests.
[0029] Specifically, in some embodiments, Figure 2As shown, a placement station 13 and a test station 14 are arranged in the housing 1, and the test station 14 is located on the optical path of the light source 22 of the test device 2. The guide structure 11 extends from the placement station 13 to the test station 14, so that the grating 21 has a movable stroke from the placement station 13 to the test station 14. In this arrangement, since the grating 21 has a movable stroke from the placement station 13 to the test station 14, and the test station 14 is located on the optical path of the light source 22 of the test device 2, the moving trajectory of the grating 21 intersects with the optical path of the light source 22, and the two test processes can be switched by moving the position of the grating 21.
[0030] The driving method of the mounting seat 31 is not limited, as long as the mounting seat 31 can be moved on the guide structure 11. In some embodiments, such as Figure 2 As shown, the switching device 3 further includes a driving assembly 32, and the driving assembly 32 includes a guide portion 321 disposed on one side of the guide structure 11 and a driving portion 322 connected to an air pipe. The extension direction of the guide portion 321 is consistent with the extension direction of the guide structure 11. The driving portion 322 is movably disposed on the guide portion 321 and connected to the mounting seat 31. Since the extension direction of the guide portion 321 is consistent with the extension direction of the guide structure 11, the mounting seat 31 is driven to move on the guide structure 11 by the movement of the driving portion 322 on the guide portion 321. The driving assembly 32 can be an electric push rod or a cylinder, including but not limited to other devices known to those skilled in the art that can drive the mounting seat 31 to move in a translational manner.
[0031] When the driving part 322 moves on the guide part 321, if the driving part 322 moves excessively, the driving part 322 will hit the end of the guide part 321. After long-term use, the driving part 322 will be damaged. Therefore, in some embodiments, Figure 2 As shown, buffer portions 323 are provided at both ends of the guide portion 321. With such a configuration, the buffer portions 323 can limit the driving portion 322 on the one hand, preventing the driving portion 322 from excessively moving and detaching from the guide portion 321, and can also prevent the driving portion 322 from colliding with the end of the guide portion 321, causing damage to the driving portion 322. Specifically, the buffer portion 323 can be a buffer, or other elastic buffer portion 323 member.
[0032] Furthermore, in some embodiments, Figure 2 and Figure 3As shown, the switching device 3 further includes a solenoid valve 33 and a switching button 34. The solenoid valve 33 is connected to the driving part 322 through the air pipe. The switching button 34 is arranged at one end of the housing 1, and the switching button 34 is electrically connected to the solenoid valve 33. The driving assembly 32 is a double-acting cylinder. Both ends of the driving part 322 are connected to the air pipe. The air pressure is applied by the air in the air pipe to drive the driving part 322 to reciprocate on the guide part 321. Since the solenoid valve 33 is connected to the driving part 322 through the air pipe, the solenoid valve 33 can control the movement of the driving part 322 by switching. The switching button 34 is electrically connected to the solenoid valve 33. Pressing the switching button 34 can control the switch of the solenoid valve 33, thereby controlling the movement of the driving part 322.
[0033] When the driving unit 322 moves too fast, it may cause the driving unit 322 to be difficult to control and excessive movement may occur. When the driving unit 322 moves too slowly, the speed at which the mounting seat 31 moves from the placement station 13 to the test station 14 may be too slow, resulting in low test efficiency. Therefore, in some embodiments, Figure 2 As shown, the switching device 3 also includes a regulating unit 35 for adjusting the air pressure of the trachea, and the regulating unit 35 is connected to the driving unit 322 through the trachea. In this way, the air pressure of the trachea is adjusted by the regulating unit 35, thereby adjusting the moving speed of the driving unit 322, and the operator can adjust the moving speed of the driving unit 322 in real time according to actual needs.
[0034] Before testing the module to be tested, it is necessary to scan the module to be tested to determine the ID of the module to be tested. Generally, the module to be tested is first placed on a code scanning device for scanning, and then the module is placed on a testing device for testing. However, in this process, the ID of the module to be tested may not match the module that has completed the test. Therefore, in some embodiments, Figure 1 As shown, the fingerprint module testing device 100 further includes a code scanning device 4, which is arranged on one side of the housing 1, and the mounting port 12 is located in the code scanning area of the code scanning device 4. In this arrangement, the code scanning device is combined with the testing device, and the operator only needs to place the fingerprint module on the mounting port 12, and the code scanning device 4 can scan the code. After the code scanning is completed, there is no need to move the module, and the next step of testing can be carried out directly, which greatly improves the work efficiency.
[0035] Preferably, in some embodiments, Figure 1As shown, the test equipment further includes a connecting component 5 and a fixing component 6 for fixing the code scanning device 4. The connecting component 5 is arranged on one side of the housing 1, and the fixing component 6 is movably connected to the connecting component 5. The code scanning device 4 is fixed to one side of the housing 1 by the connecting component 5 and the fixing component 6. The connecting component 5 can be arranged on one side of the housing 1 in the x direction or on one side in the y direction. The specific setting position is determined according to the test site.
[0036] Furthermore, the structure of the connecting component 5 is not limited, as long as the connecting component 5 is arranged on one side of the housing 1 and the connecting component 5 can be connected to the fixing component 6. For example, in some embodiments, Figure 1 As shown, the connecting component 5 also includes a first connecting portion 51, a second connecting portion 52 and a third connecting portion 53, the first connecting portion 51 is arranged at one side of the housing 1, the second connecting portion 52 is movably mounted on the first connecting portion 51 along the z direction, the third connecting portion 53 is movably mounted on the second connecting portion 52 along the y direction, and the fixing component 6 is movably mounted on the third connecting portion 53 along the x direction. With such arrangement, the code scanning device 4 can be movable relative to the housing 1 in the x direction, the y direction and the z direction. Since the coding positions of different fingerprint modules may be different, the tester can adjust the position of the code scanning device 4 according to different coding positions, so that the code scanning device 4 is directly opposite to the coding position in the z direction, so as to improve the recognition rate and recognition speed of the code scanning device 4.
[0037] Furthermore, the specific structure of the fixing component 6 is not limited, as long as the fixing component 6 can fix the code scanning device 4. For example, in some embodiments, Figure 1 As shown, the fixing assembly 6 includes a connection seat 61 and a fixing portion 62 for fixing the code scanning device 4, the connection seat 61 is connected to the connection assembly 5, and the fixing portion 62 is rotatably mounted on the connection seat 61 along an axis extending in the x direction. Generally, when the code scanning device 4 is facing the coding position of the module to be tested in the z direction, the recognition rate and recognition speed of the code scanning device 4 are the highest, but sometimes affected by light, the code scanning device 4 facing the coding position cannot obtain a good recognition rate and recognition speed. At this time, the tester can rotate the fixing portion 62 and adjust the angle of the code scanning device 4 to obtain a better recognition rate and recognition speed.
[0038] The operator can directly place the module to be tested on the installation opening 12 for testing. However, since the size of the installation opening 12 is fixed, the test equipment can only be applied to fingerprint modules of certain sizes. In order to apply to fingerprint modules of more different sizes, in some embodiments, such as Figure 3As shown, the fingerprint module testing device 100 further includes a mounting portion 7, the mounting portion 7 covers the mounting opening 12, and the mounting portion 7 is provided with a mounting hole 71 for mounting the module to be tested, and the mounting hole 71 is located on the optical path of the light source 22 of the testing device 2. With such an arrangement, the fingerprint module of different sizes can be applied only by replacing the mounting portion 7 with mounting holes 71 of different sizes, and the production cost is low.
[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
