The first embodiment, as shown in Figure 6, for the camera module of Figure 1, the utility model test fixture includes a base plate 15, a support block 22, a large test board 6, a support column 20 and a test adapter plate 5, the support block 22 includes a product support block 21, a test board support block 13, and the bottom plate 15 is provided with a symmetrical test large board fixing groove 16 along the central axis and a test adapter board support block fixing groove 18 along the vertical direction of the test large board fixing groove 16 , one end of the test adapter board 5 is connected to the test large board 6, and the other end is lapped on the test board support block 13, the diameter of the support column 20 is smaller than the fixing groove, the support column 20 is placed in the fixing groove 16, and the test large board 6 passes The support column 20 and the bottom plate 15 are slidably connected along the first direction, the first direction is the direction along the axis of symmetry of the bottom plate 15, the bottom plate 15 and the support block 22 are slidably connected along the second direction, the second direction is perpendicular to the first direction, and the connector 4 is installed on the test adapter board 5. Fix the test large plate support column 20 on the bottom surface of the large plate with screws; according to the position of the positioning hole on the test large plate, the large plate is fixed on the base plate 15 with screws; connect one end of the test adapter plate 5 with the test large plate 6 connected; put the step of the test adapter plate support block 13 against the other end of the test adapter plate 5, and then fix the support block on the bottom plate through the screw hole at the bottom of the support block. The installation position of the support block can be on the adapter plate End face or side; connect one end of the camera with the flexible circuit board (FPC) 2 to the test connector 4 on the test adapter board through the golden finger. According to the actual position of the product, install the product support block 21, adjust the position of the support block along the second direction, then be fixed on the base plate 15 with screws, so that the product is just fixed in the groove of the product support block.

Its position can be adjusted according to needs: if the product is too long and exceeds the product support block 21, or is too short and does not reach the position, it is necessary to adjust the position of the test large plate along the first direction by adjusting the position of the large plate support column 20 , so that the position of the test adapter plate 5 is also adjusted accordingly; if the product position is too low, it is necessary to add a gasket of appropriate thickness between the support column 20 and the screw of the test large plate to improve the position of the test large plate, so that the test adapter plate The position of the product should also be adjusted accordingly; if the product position is too high, it is necessary to add spacers between the bottom of the product support block and the screws, or choose a product support block with a larger thickness.

After installation as shown in Figure 7, connect to the computer through the USB interface on the test adapter board, start its test program, and test.

The second embodiment, as shown in Figure 7, for the camera module shown in Figure 2, the difference between this embodiment and the first embodiment is that the test fixture also includes a pressure plate support block 14, a pressure plate 9, and an opening on the bottom plate 15. There is a fixing groove 17 for the supporting block of the pressing plate, and the supporting block 22 is the supporting block 13 for the test plate. Fix the test large plate support column 20 on the bottom surface of the large plate with screws; according to the position of the positioning hole on the test large plate, the large plate is fixed on the base plate 15 with screws; connect one end of the test adapter plate 5 with the test large plate 6 connected; put the step of the test adapter plate support block 13 against the other end of the test adapter plate 5, and then fix the support block on the bottom plate through the screw hole at the bottom of the support block. The installation position of the support block can be on the adapter plate End face or side; test adapter plate 5 is welded with test connector 4, the camera module is connected to test connector 4 through lens connector 3; press plate support block 14 is fixed in the press plate support block fixing groove 19 on the base plate The two sides of the pressure plate 9 are hinged with the pressure plate support block 14 by screws; the position of the pressure plate support block 14 is adjusted along the second direction, so that after the pressure plate is pressed down, the lens hole 10 is completely aligned with the product lens 1, and the pressure plate 9 is in a horizontal state.

The position can be adjusted according to the needs: if the pressing plate cannot be reached when it is pressed down, and it is in a downward tilting state, it means that the position of the camera module is too low, and it is necessary to use spacers to increase the height of the test board and the position of the adapter plate; if the pressing plate is pressed If the bottom is tilted up, it means that the product is too high, and it is necessary to use gaskets and high pressure plate support blocks.
