[0023] 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.

[0024] See also Figure 1 , Figure 2 and Figure 3As shown, a camera module automatic positioning test device 10 includes: a camera module 100 and a lateral positioning module 200, the lateral positioning module 200 includes a base 210, a sliding support 220, a driving member 230, a left-side in-place sensor 240, a middle in-place sensor 250 and a right-side in-place sensor 260, the sliding support 220 is located on the base 210, the camera module 100 is installed on the sliding support 220, and the driving member 230 is connected to the sliding support 220, the left-side in-place sensor 240 and the right-side in-place sensor 260 are respectively arranged at two ends of the base 210, the middle in-place sensor 250 is arranged between the left-side in-place sensor 240 and the right-side in-place sensor 260, and an in-place sensing block 270 is arranged on the sliding support 220, the driving member 230 is used to drive the sliding support 220 to perform a lateral reciprocating displacement along the base 210, so that the in-place sensing block 270 passes through the left-side in-place sensor 240, the middle in-place sensor 250 and the right-side in-place sensor 260 respectively.

[0025] It should be noted that before performing a shooting test operation on the camera module, it is necessary to adjust the position of the camera module automatic positioning test device 10 and the ISO chart, and at the same time adjust the relative position between the camera module automatic positioning test device 10 and the ISO chart to ensure that after the camera module outputs the image, its shooting center is aligned with the center of the ISO chart, that is, the center position is defined as the shooting center of the camera module, that is, the position of the middle in-place sensor 250 can make the position where the camera module 100 stops as the shooting center. Then, the driving member 230 can drive the sliding support member 220 to move to the left or right. For example, the driving member 230 drives the sliding support member 220 to move horizontally to the left. When the in-position sensing block 270 on the sliding support member 220 passes over the left in-position sensor 240, the left in-position sensor 240 identifies and limits the position, thereby controlling the camera module 100 to stop at the test position, which is defined as the left four corners shooting test position of the ISO chart; then, the driving member 230 drives the sliding support member 220 to move horizontally to the right. When the in-position sensing block 270 on the sliding support member 220 passes over the right in-position sensor 240, the right in-position sensor 260 identifies and limits the position, thereby controlling the camera module 100 to stop at the test position, which is defined as the right four corners shooting test position of the ISO chart. After determining the relative position, the subsequent camera module can be tested. Furthermore, the camera module 100 is driven to move in positioning through the lateral positioning module 200. Specifically, the camera module 100 is supported by the sliding support member 220, and the sliding support member 220 is driven by the driving member 230 to pass through the left-side in-position sensor 240, the middle in-position sensor 250 and the right-side in-position sensor 260 respectively, so that the positioning stop of the sliding support member can be controlled by the left-side in-position sensor, the middle in-position sensor and the right-side in-position sensor, instead of manually adjusting the position of the camera module, to realize automatic positioning test operation on the camera module, thereby improving the shooting test accuracy of the camera module.

[0026] In one embodiment, the sliding support member 220 includes a sliding block 221 and a sliding support plate 222. The sliding block 221 is connected to the driving member 230. The sliding support plate 222 is arranged on the sliding block 221, and the in-position sensing block 270 is arranged on a side surface of the sliding support plate 222. The sliding block 221 is installed on the driving end of the driving member 230. For example, the driving member 230 is a motor screw drive structure. The motor screw drive structure mainly includes a motor 231 and a screw 232. One end of the screw is arranged on the driving end of the motor, and the sliding block 221 is installed on the screw. The motor drives the screw to rotate, thereby driving the sliding block 221 to perform a lateral linear displacement along the screw. The use of the motor screw drive structure can ensure the accuracy of the moving position of the sliding support member 220 and the stability of the movement. Furthermore, in order to improve the movement stability of the sliding support 220, a guide rail can be provided on the base 210, and a slider can be provided on the sliding block 221. The slider is slidably provided on the guide rail to guide the movement of the sliding support 220, thereby further improving the movement stability. Furthermore, a buffer limit block 221a is provided in the movement direction of the sliding block 221 along the sliding support 220. The buffer limit block 221a is used for limiting and buffering to prevent the sliding block 221 from hitting the two ends of the base and causing damage when the driving member is abnormal. For example, the buffer limit block 221a is a rubber buffer block.

[0027] See also Figure 2 As shown, in one embodiment, the lateral positioning module 200 also includes a dust cover 280, which is arranged on the top of the base 210, and a limit cavity is opened on the base 210, and the sliding support 220 is located in the limit cavity. At the same time, the screw in the motor screw drive structure is also located in the limit cavity. The dust cover 280 blocks the screw and the sliding support 220. In this way, dust can be prevented from accumulating on the screw and the sliding support 220, thereby affecting the accuracy of the moving position of the sliding support 220.

[0028] Furthermore, the sliding support plate 222 is provided with a first mounting protrusion 222a and a second mounting protrusion 222b, an avoidance groove 222c is formed between the first mounting protrusion 222a and the second mounting protrusion 222b, the dust cover 280 is located in the avoidance groove 222c, and the camera module 100 is installed on the first mounting protrusion 222a and the second mounting protrusion 222b. By providing the first mounting protrusion 222a and the second mounting protrusion 222b, it is convenient to avoid the dust cover 280, so as to install the camera module 100 on the sliding support plate 222.

[0029] Furthermore, the in-position sensing block 270 includes a mounting portion 271, an extension portion 272 and a sensing portion 273. The mounting portion is mounted on one side of the sliding support plate, one end of the extension portion is connected to the mounting portion, and the other end of the extension portion extends away from the mounting portion and is connected to the sensing portion. The sensing portion and the extension portion form a preset angle, for example, the preset angle is 90 degrees. At the same time, the sensing portion is arranged downward, so that the sensing portion can be moved to the left in-position sensor 240, the middle in-position sensor 250 and the right in-position sensor 260.

[0030] Furthermore, the left in-place sensor 240 is provided with a first sensing protrusion 241 and a second sensing protrusion, and a sensing groove is formed between the first sensing protrusion and the second sensing protrusion. When the driving member drives the sliding support member to move to the left in-place sensor, the sensing portion 273 on the in-place sensing block 270 is located in the sensing groove. In this embodiment, the structure of the middle in-place sensor and the right in-place sensor is the same as that of the left in-place sensor. For example, the left in-place sensor 240, the middle in-place sensor 250 and the right in-place sensor 260 are all photoelectric induction limit switches. In addition, a strip-shaped adjustment installation groove is provided on the side wall of the base 210. By adjusting the installation groove, the positions of the left in-place sensor 240, the middle in-place sensor 250 and the right in-place sensor 260 can be adjusted and installed.

[0031] Furthermore, the camera module automatic positioning test device 10 also includes a support frame 300, and the lateral positioning module 200 is arranged on the support frame 300. The support frame 300 is a triangular support frame to ensure the installation stability of the lateral positioning module. A height adjustment structure is arranged on the top of the support frame 300, and the height of the lateral positioning module is adjusted by the height adjustment structure. For example, an adjustment rod is arranged at the bottom of the base 210, and a mounting hole is arranged on the top of the support frame 300. The adjustment rod is inserted into the mounting hole. After the position adjustment is completed, it can be locked by bolts.

[0032] In one embodiment, the camera module 100 includes a test frame and a camera. The test frame is installed on a sliding support, and the camera is installed on the test frame. The test frame is used to fix the camera, and the signal box is also set on the test frame.

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.
