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.

[0032] Reference Figure 1 - Figure 3 This utility model provides an embodiment of a camera module testing device, including a base 1. A viewfinder 2 is fixedly connected to the left outer wall of the base 1. The viewfinder 2 is existing technology. By bringing the camera module, which is fixed to the surface of the placement seat 85, closer to the viewfinder 2, the movement imaging test of the camera module can be determined. An electric slide rail 3 is provided on the surface of the base 1. The electric slide rail 3 is existing technology. A control motor is provided on the outer side of the base 1, which can drive the electric slide rail 3 to move the slider 4 laterally, thereby pushing the fixed camera module to perform the movement imaging test. The slider 4 is slidably connected to the inner wall of the electric slide rail 3. A support seat 5 is slidably connected to the top of the outer wall of the slider 4. A positioning component 8 is provided at the top of the support seat 5.

[0033] Reference Figure 1 - Figure 3 The positioning component 8 includes a fixed base 81, which is rotatably connected to the surface of the top of the support base 5. Two sets of placement seats 85 are fixedly connected to the surface of the fixed base 81. By providing two sets of placement seats 85, a quick switch can be made after one set of camera modules has completed its detection. A trapezoidal block 87 is elastically connected to the inner wall of the placement seat 85 via a return spring 86. The trapezoidal block 87 is slidably connected to the inner wall of the placement seat 85. The inner wall of the placement seat 85 has a cavity, so that the trapezoidal block 87 can only move laterally within the inner wall of the placement seat 85. One end of the return spring 86 is fixed. The other end of the return spring 86 is fixedly connected to the outer wall of the trapezoidal block 87, and the other end is fixedly connected to the inner wall of the placement seat 85. The function of the return spring 86 is to push the contact block 812 to move the trapezoidal block 87 to the position after it has moved on the inner wall of the placement seat 85 after the contact block 812 and the elliptical block 83 come into contact. Both sides of the outer wall of the trapezoidal block 87 are slidably connected to L rods 88. Guide grooves that fit the L rods 88 are opened on both sides of the trapezoidal block 87, so that the back and forth movement of the trapezoidal block 87 will push the upper and lower sets of L rods 88 to move closer or further away from each other on the inner walls of the inclined grooves on both sides.

[0034] Reference Figure 2 and Figure 3L-rod 88 is slidably connected to the inner wall of the placement seat 85. The inner wall of the placement seat 85 has a guide groove that fits L-rod 88, so that L-rod 88 can only move vertically and cannot move laterally. The end of L-rod 88 away from trapezoidal block 87 is fixedly connected to a movable seat 89. When the two sets of L-rods 88 are pushed together by trapezoidal block 87, they will simultaneously drive the movable seat 89 to move together, so that the positioning block 811 can press the camera module. The inner wall of the front end of the movable seat 89 has an internal thread, and a screw 810 is threadedly connected to the inner wall of the front end of the movable seat 89. The bottom end of the outer wall of the screw 810 is connected to... The positioning block 811 has a horizontal groove on its surface. The screw 810 moves along the thread to contact the inner wall of the horizontal groove of the positioning block 811. This provides positioning support for the positioning block 811 after it has been adjusted according to the size of the camera module. The positioning block 811 is made of hard rubber and is slidably connected to the inner wall of the moving base 89. The positioning block 811 can move along the inner wall of the moving base 89, allowing the spacing of the positioning block 811 on the inner wall of the moving base 89 to be adjusted according to the size of the camera module, thus better fitting the camera module.

The contact block 812 passes through and is slidably connected to the side wall of the placement seat 85. An elliptical block 83 contacts the outer wall of the contact block 812. When the fixed seat 81 rotates, it will drive the two sets of placement seats 85 to rotate synchronously. When one set of placement seats 85 rotates to the center of the support seat 5, the contact block 812 sliding on its inner side will be squeezed by the elliptical block 83, so that it moves on the inner wall of the placement seat 85. This allows the trapezoidal block 87 to drive the two sets of L rods 88 and the corresponding moving seats 89 to press the camera module. The elliptical block 83 is elliptical in shape and located near the right side of the fixed base 81. A connecting rod 82 is fixedly connected to the surface of the elliptical block 83. The end of the connecting rod 82 away from the elliptical block 83 is fixedly connected to the outer wall of the bottom of the support base 5. The elliptical block 83 can be connected and supported by the connecting rod 82. A motor 84 is fixedly connected to the outer wall of the top of the support base 5. The output shaft of the motor 84 is fixedly connected to the rotation center shaft of the fixed base 81. A limit component 6 is provided on the inner wall of the bottom of the support base 5.

The telescopic rod 62 is rotationally connected to the outer wall of the bottom end of the support base 5, and the end of the telescopic rod 62 away from the insertion rod a61 is hingedly connected with the insertion rod b63. When the insertion rod a61 rises, the insertion rod a61 rotates around the rotation center point through the telescopic rod 62 and pushes the insertion rod b63 to fall. Conversely, when the insertion rod b63 rises, the insertion rod b63 pushes the insertion rod a61 to fall through the telescopic rod 62 around the rotation center point. The insertion rod a61 is penetratingly and slidingly connected to the inner wall of the bottom end of the support base 5, and the insertion rod b63 is penetratingly and slidingly connected to the inner wall of the bottom end of the support base 5.

The limiting spring 64 is used to automatically reset the position of the insertion block 65 after the insertion block 65 is pulled outward. The insertion block 65 is penetratingly and slidingly connected to the inner wall of the insertion rod a61. The outer wall of the bottom end of the support base 5 is provided with two groups of through holes in the up-down direction. The end of the insertion block 65 is inserted into the inner wall of the through hole, and the insertion block 65 is in insertion with the through hole, so that the position of the insertion rod b63 in contact with the inner wall of the wave-shaped groove 7 and the position of the insertion rod a61 in series connection with the sliding block 4 can be fixed respectively. The left surface of the base 1 is provided with the wave-shaped groove 7.
