Obviously, the described embodiments are some of the embodiments of the application but not all the embodiments of the application. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the application.

The laser ranging module 140 is used to measure the extension distance of the lens assembly in the camera module to be tested.

[0033] Figure 1 The three-dimensional coordinate system is only for indicating direction and has no other meaning. For convenience of description, right refers to +X direction, left refers to -X direction, back refers to +Y direction, front refers to -Y direction, up refers to +Z direction, and down refers to -Z direction.

[0034] The micro motor extension test equipment is a left-right symmetrical structure, that is, two groups of camera modules to be tested can be tested simultaneously or alternately. In this embodiment, the laser ranging adjustment module on the right side is taken as an example for description. The laser ranging adjustment module includes a plane adjustment module 110, an inclination adjustment module 120, and a support module 130.

[0035] The plane adjustment module 110 is fixed on the bottom carrier 160 by bolts. The support module 130 is fixed on the plane adjustment module 110 by bolts. The inclination adjustment module 120 and the power supply module 150 are fixed on the support module 130 by bolts, respectively. The laser ranging module 140 is fixed on the inclination adjustment module 120 by bolts.

[0036] The plane adjustment module 110 is located behind the positioning module 100 and is fixed on the bottom carrier 160. The plane adjustment module 110 drives the laser ranging adjustment module to move along the X-axis and Y-axis directions through the support module 130, thereby driving the laser ranging module 140 to align and calibrate with the lens assembly in the X-axis and Y-axis directions.

[0037] As shown in FIG. 2, the plane adjustment module 110 includes a plane adjustment plate 111 and a plurality of adjustment screws 112. The plane adjustment plate 111 is fixed on the bottom carrier 160 by bolts. The support module 130 is fixed on the plane adjustment plate 111 by bolts. The inclination adjustment module 120 and the power supply module 150 are fixed on the support module 130 by bolts, respectively. The laser ranging module 140 is fixed on the inclination adjustment module 120 by bolts. Figure 2As shown, the planar adjustment module 110 includes an X-axis bottom plate 60, a Y-axis left linear rail 61, a Y-axis clamping block 62, a Y-axis micrometer 63, a Y-axis micrometer fixing block 64, a Y-axis right linear rail 65, an X-axis rear linear rail 66, an X-axis micrometer fixing block 67, an X-axis micrometer 68, an X-axis clamping block 69, an X-axis front linear rail 70, an X-axis heavy-duty tension spring 71, a Y-axis bottom plate 72, and a Y-axis heavy-duty tension spring 73. The Y-axis bottom plate 72 is slidably connected to the bottom carrier 160 through the Y-axis left linear rail 61 and the Y-axis right linear rail 65, the X-axis bottom plate 60 is slidably connected to the Y-axis bottom plate 72 through the X-axis rear linear rail 66 and the X-axis front linear rail 70, and the upper end of the X-axis bottom plate 60 is provided with a mounting hole for connecting with the support module 130.

[0038] The Y-axis left linear rail 61 and the Y-axis right linear rail 65 are both arranged along the Y-axis and are fixed on the bottom carrier 160 by bolts. The left and right ends of the Y-axis bottom plate 72 are fixed on the sliding blocks of the Y-axis left linear rail 61 and the Y-axis right linear rail 65 by bolts, respectively. Figure 3 As shown, the Y-axis heavy-duty tension spring 73 is arranged along the Y-axis direction and can be stretched along the Y-axis direction. The rear ends of one or more Y-axis heavy-duty tension springs 73 are fixed on the bottom carrier 160 by bolts, and the front ends of the Y-axis heavy-duty tension springs 73 are fixed on the lower end of the Y-axis bottom plate 72 by bolts. The Y-axis heavy-duty tension springs 73 are always in a stretched state, so that the Y-axis bottom plate 72 moves from front to back along the Y-axis.

[0039] The Y-axis micrometer 63 is installed on the bottom carrier 160 through the Y-axis micrometer fixing block 64. The Y-axis micrometer 63 is located behind the Y-axis bottom plate 72, and the distance between the Y-axis micrometer 63 and the Y-axis left linear rail 61 is the same as the distance between the Y-axis micrometer 63 and the Y-axis right linear rail 65. The Y-axis micrometer 63 is provided with a first adjusting knob and a first guide shaft, and the first guide shaft abuts against the middle part of the rear end of the Y-axis bottom plate 72. The Y-axis clamping block 62 is located on the same straight line as the first guide shaft and is fixed on the bottom carrier 160 by bolts. The Y-axis clamping block 62 is used to clamp and limit the first guide shaft.

[0040] In the initial state of the Y-axis bottom plate 72, the Y-axis heavy-duty tension spring 73 is in a stretched state. After the Y-axis clamping block 62 is released, the first guide shaft can move forward and backward along the Y-axis, and the Y-axis bottom plate 72 can move forward and backward along the Y-axis left linear rail 61 and the Y-axis right linear rail 65. When the first adjusting knob is rotated to move the first guide shaft forward along the Y-axis, the Y-axis bottom plate 72 is pushed to move forward against the tension of the Y-axis heavy-duty tension spring 73. When the first adjusting knob is rotated to move the first guide shaft backward along the Y-axis, the first guide shaft moves from front to back, and at the same time, the Y-axis bottom plate 72 moves backward under the action of the tension of the Y-axis heavy-duty tension spring 73. After the position adjustment in the Y-axis direction is completed, the first guide shaft is clamped and limited by the Y-axis clamping block 62 to prevent the Y-axis bottom plate 72 from moving in the Y-axis direction, thereby realizing the positioning in the Y-axis direction.

[0041] Both the X-axis rear guide rail 66 and the X-axis front guide rail 70 are set along the X-axis and are fixed to the upper end of the Y-axis base plate 72 by bolts. The front and rear ends of the X-axis base plate 60 are fixed to the sliders of the X-axis front guide rail 70 and the X-axis rear guide rail 66 by bolts, respectively. The X-axis heavy-duty tension spring 71 is set along the X-axis direction and can extend and retract along the X-axis direction. The right ends of one or more X-axis heavy-duty tension springs 71 are evenly fixed to the upper end of the Y-axis base plate 72 by bolts, and the left ends of the X-axis heavy-duty tension springs 71 are fixed to the lower end of the X-axis base plate 60 by bolts. The X-axis heavy-duty tension springs 71 are always in a stretched state, pulling the X-axis base plate 60 to move from left to right along the X-axis.

[0042] The X-axis micrometer 68 is mounted on the right end of the Y-axis base plate 72 via the X-axis micrometer fixing block 67. The X-axis micrometer 68 is equidistant from the X-axis front guide rail 70 and the X-axis rear guide rail 66. The X-axis micrometer 68 is equipped with a second adjustment knob and a second guide shaft, which abuts against the middle of the right end of the X-axis base plate 60. The X-axis clamping block 69 is located on the same straight line as the second guide shaft and is fixed to the bottom carrier 160 by bolts. The X-axis clamping block 69 is used to clamp the second guide shaft and limit its position.

[0043] In the initial state, the X-axis base plate 60 is in a stretched state with the X-axis heavy-duty tension spring 71 in the stretched state. After the X-axis clamping block 69 is released, the second guide shaft can move left and right along the X-axis, and the X-axis base plate 60 can move left and right along the X-axis front rail 70 and the X-axis rear rail 66. When the second adjustment knob is rotated to move the second guide shaft to the left along the X-axis direction, the second guide shaft moves from right to left, pushing the X-axis base plate 60 to move to the left against the tension of the X-axis heavy-duty tension spring 71. When the first adjustment knob is rotated to move the second guide shaft to the right along the X-axis direction, the first guide shaft moves from left to right, and the X-axis base plate 60 moves to the right under the tension of the X-axis heavy-duty tension spring 71. After the X-axis position adjustment is completed, the second guide shaft is clamped and limited by the X-axis clamping block 69 to prevent the X-axis base plate 60 from shifting in the X-axis direction, thus achieving positioning in the X-axis direction.

[0044] like Figure 4 As shown, the tilt adjustment module 120 is located between the front end of the support module 130 and the laser ranging module 140. The tilt adjustment module 120 is used to adjust the tilt angle of the laser ranging module 140 in the X and Y axes, and to adjust the height of the laser ranging module 140 in the Z axis direction.

[0045] The inclination adjustment module 120 comprises a Z-axis micrometer 74, a Z-axis micrometer fixing block 75, a Z-axis clamping block 76, an X-axis inclination adjustment block 77, a fixing member with a second bearing 78, a guide rod 79, a test head fixing plate 80, an X-axis inclination fixing plate 81, an X-axis inclination adjustment plate 82, a Y-axis inclination fixing plate 83, a Y-axis ball head set screw 84, a first bearing 85, an X-axis ball head set screw 86, an adjustment block 87, a pull pin 88, a Y-axis heavy load tension spring 89, a cross roller 90, an X-axis heavy load tension spring 91, a test head pad 92, and a Z-axis heavy load tension spring 93. The specific component connection relationship is as follows:

[0046] As shown in Figure 5 , the upper end of the X-axis inclination adjustment plate 82 is rotationally connected with the upper end of the Y-axis inclination fixing plate 83. Specifically, the Y-axis inclination fixing plate 83 is fixed at the front end of the support module 130 by bolts, and the upper end of the Y-axis inclination fixing plate 83 is provided with two locking holes in the X-axis direction, which lock the guide rod 79. The two ends of the guide rod 79 respectively pass through the two locking holes and are connected with the second bearings provided on the fixing member 78. The fixing member 78 is fixed on the upper end of the X-axis inclination adjustment plate 82 by screws, and drives the X-axis inclination adjustment plate 82 to rotate around the guide rod 79 in the Y-axis direction.

[0047] As shown in Figure 6 , the X-axis inclination adjustment plate 82 is located at the front end of the Y-axis inclination fixing plate 83, and the Y-axis inclination fixing plate 83 and the X-axis inclination adjustment plate 82 are clamped together by the tension of the Y-axis heavy load tension spring 89. In this embodiment, a plurality of Y-axis heavy load tension springs 89 are evenly distributed between the Y-axis inclination fixing plate 83 and the X-axis inclination adjustment plate 82. The Y-axis heavy load tension spring 89 is arranged along the Y-axis and can stretch in the Y-axis direction. The Y-axis inclination fixing plate 83 and the X-axis inclination adjustment plate 82 are provided with through holes in the Y-axis direction at positions corresponding to the Y-axis heavy load tension spring 89. The front and rear ends of the Y-axis heavy load tension spring 89 are fixed on the through holes of the X-axis inclination adjustment plate 82 and the Y-axis inclination fixing plate 83 by the pull pin 88.

[0048] The lower end of the Y-axis inclination fixing plate 83 is provided with a through hole in the Y-axis direction. The Y-axis adjustment ball head set screw 84 is threadedly connected with the through hole and can move forward and backward in the through hole. The ball head of the Y-axis adjustment ball head set screw 84 faces the X-axis inclination adjustment plate 82. By moving the ball head of the Y-axis adjustment ball head set screw 84 forward along the Y-axis direction to push the X-axis inclination adjustment plate 82, and under the joint action of the elastic force of the Y-axis heavy load tension spring 89, the X-axis inclination adjustment plate 82 rotates in the Y-axis direction, thereby achieving the inclination adjustment of the X-axis inclination adjustment plate 82 in the Y-axis direction, and achieving the purpose of adjusting the Y-direction inclination of the laser ranging module 140.

[0049] As shown in Figure 7As shown, the X-axis inclination fixing plate 81 is located at the front end of the X-axis inclination adjusting plate 82. The inner ring of the first bearing 85 is fixed to the lower part of the front end face of the X-axis inclination adjusting plate 82 by bolts, and the X-axis inclination adjusting plate 82 is provided with a positioning column, and the inner ring of the first bearing 85 is sleeved outside the positioning column. The outer ring of the first bearing 85 is fixed to the rear end face of the X-axis inclination fixing plate 81 by bolts, and the outer ring of the first bearing 85 can rotate around the inner ring of the first bearing 85, so that the X-axis inclination fixing plate 81 rotates along the X-axis inclination adjusting plate 82 in the X-axis direction.

[0050] One or more X-axis inclination heavy load extension springs 91 are uniformly arranged along the X-axis and can stretch in the X-axis direction. One end of the X-axis inclination heavy load extension spring 91 is fixed to the rear end face of the X-axis inclination fixing plate 81, and the other end is fixed to the front end face of the X-axis inclination adjusting plate 82.

[0051] Two X-axis ball head stop screws 86 are arranged on the left and right sides of the top end of the X-axis inclination adjusting plate 82 through adjusting blocks 87, respectively. The adjusting block 87 can adjust the distance between the X-axis inclination adjusting block 77 and the X-axis inclination adjusting plate 82. The X-axis ball head stop screw 86 is arranged along the X-axis. The adjusting block 87 is provided with a threaded hole along the X-axis direction, and the X-axis ball head stop screw 86 is threadedly connected through the threaded hole, and the X-axis ball head stop screw 86 can move forward and backward in the threaded hole. The heads of the two X-axis ball head stop screws 86 respectively abut against the left and right ends of the X-axis inclination fixing plate 81. By adjusting the distance between the heads of the left and right X-axis ball head stop screws 86 and the threaded hole, the upper end of the X-axis inclination adjusting plate 82 is moved in the X-axis direction, and under the elastic force of the X-axis inclination heavy load extension spring 91, the X-axis inclination fixing plate 81 is rotated in the X-axis direction, so as to adjust the inclination angle of the X-axis inclination fixing plate 81 in the X-axis direction, thereby achieving the purpose of adjusting the X-axis inclination angle of the laser ranging module 140.

[0052] The test head fixing plate 80 is installed on the front end face of the X-axis inclination fixing plate 81 through the cross roller 90, and the test head fixing plate 80 can slide up and down along the Z-axis direction on the X-axis inclination fixing plate 81 along the cross roller 90; the test head fixing plate 80 and the laser ranging module 140 are provided with test head pads 92, and the test head pads 92 are uniformly installed on the front end face of the test head fixing plate 80.
