Description

Technical Field

[0001] The utility model relates to the field of camera module testing, and in particular to a camera module testing fixture. Background Art

[0002] Before the camera module leaves the factory, it is necessary to test the performance of the camera module after it is powered on (for example: short circuit detection, open circuit detection, focus range detection, etc.) to ensure that the camera module has accurate focus, reliable operation and stable performance after leaving the factory. Before testing the performance of the camera module after it is powered on, the camera module will first be fixed on the testing platform (for example, by clamping the two sides of the camera module with a fixture), and then the connector in the camera module will be electrically connected through an external circuit. However, the existing camera module test fixture directly presses on the connector during the fixing and connection of the connector, which will cause the connector to be crushed, thereby damaging the product and affecting the product yield.

The surface of the connector 91 is provided with multiple connection points, which are used to electrically connect the camera module 90. The camera module 90 can be tested by electrically connecting the connection points on the connector 91 to a camera module test fixture.

[0039] Please continue reading Figure 2-Figure 5As shown, in this specific embodiment, the utility model provides a camera module test fixture for testing a camera module 90, which includes a connector 91 and a module body 92, including: a base 10, a fixing plate 20, a cover plate 30, a connector carrier 40 and a floating needle seat 50; the base 10 includes a carrier accommodating groove 11, the connector carrier 40 is arranged in the carrier accommodating groove 11, and the fixing plate 20 is installed on the base 10; the connector carrier 40 includes a floating carrier 41 and a first elastic member 42, the floating carrier 41 is arranged on the first elastic member 42 and is close to the fixing plate 20, the floating carrier 41 Used to support the connector 91; the fixing plate 20 is used to support the module body 92, and a connector placement hole 21 is provided on the fixing plate 20. The connector placement hole 21 is located directly above the carrier receiving groove 11, and the connector placement hole 21 is used to place the connector 91; the cover plate 30 is set on the base 10 and presses the module body 92; the floating needle seat 50 includes a test probe 51, the floating needle seat 50 is connected to the cover plate 30, and the test probe 51 is used to connect the connector 91. It should be noted that the connection between the test probe 51 and the connector 91 refers to an electrical connection, that is, the current can reach the connector 91 through the test probe 51. The camera module test fixture is used to support the connector 91 through the floating carrier 41 in conjunction with the first elastic member 42 to prevent the connector 91 from being damaged by excessive extrusion force, thereby solving the problem of the existing connector 91 being crushed during testing.

[0040] In one embodiment, the fixing plate 20 further includes a body receiving groove 22 for receiving the module body 92. The fixing plate 20 supports and receives the camera module 90, and a connector receiving hole 21 and a body receiving groove 22 are provided on the fixing plate 20. The cover plate 30 cooperates with the base 10 and the fixing plate 20 to press the module body 92, ensuring that the camera module 90 is stably set and does not tilt during testing. This also facilitates the precise positioning of the connector 91 on the floating platform 41 during testing.

[0041] In one embodiment, a first receiving groove 111 is defined at the bottom of the platform receiving groove 11. The first elastic member 42 is a spring structure and is located within the first receiving groove 111. The provision of the first receiving groove 111 facilitates the placement of the first elastic member 42 and prevents the first elastic member 42 from tilting under load, thereby preventing the floating platform 41 from tilting. The use of a spring structure for the first elastic member 42 facilitates the selection of existing spring materials, reducing manufacturing costs.

[0042] In one embodiment, the floating needle holder 50 further includes a probe holder 52, a second elastic member 53, and a floating pressure platform 54. The test probe 51 is connected to the cover plate 30 via the probe holder 52.

The floating pressure platform 54 is used to press the connector 91, and the test probe 51 passes through the floating pressure platform 54 to connect to the connector 91. Further, by providing the floating needle holder 50, the floating needle holder 50 mounts the test probe 51 via the probe holder 52 and presses the connector 91 via the floating pressure platform 54. The second elastic member 53 is provided between the floating pressure platform 54 and the probe holder 52 to ensure that the pressure exerted by the floating pressure platform 54 on the connector 91 is not excessive, and the pressure exerted by the floating pressure platform 54 on the connector 91 gradually increases, effectively preventing damage to the connector 91.

[0043] Building on the above solution, the floating platform 54 has a second receiving groove 541 on its surface facing the probe holder 52. The second elastic member 53 is a spring structure and is located within the second receiving groove 541. The second receiving groove 541 facilitates the placement of the second elastic member 53 and prevents the second elastic member 53 from tilting under load, thereby preventing the floating platform 54 from tilting.

[0045] In one embodiment, the camera module test fixture further includes a test circuit board 60, which is mounted on the cover 30 and electrically connected to the test probe 51. By arranging the test circuit board 60 on the cover 30, the conductive connection of the test probe 51 is facilitated.

[0046] In one embodiment, the camera module test fixture further includes a shorting assembly 70, which is connected to the base 10 and the cover 30. The shorting assembly 70 is used to determine whether the cover 30 and the base 10 are properly assembled and connected, that is, to determine whether the test probe 51 and the connector 91 are in contact and connected, thereby playing a foolproof role in assembly.

[0047] Based on the above scheme, the short-circuit assembly 70 includes a short-circuit copper seat 71 and a short-circuit needle seat 72. A short-circuit probe is provided in the short-circuit needle seat 72. The short-circuit copper seat 71 is installed on the surface of the cover plate 30 facing the base 10, and the short-circuit needle seat 72 is installed on the base 10.

[0048] In addition to the above solution, the camera module test fixture also includes a circuit board 80, on which the base 10 is mounted, and the circuit board 80 is electrically connected to the shorting probe. The circuit board 80 is used to install the camera module test fixture and also provides power to the camera module test fixture.
