Please refer to Figure 3 to Figure 5 together. Fig. 3 is the first schematic diagram of the first embodiment of the calibration device of the present invention; Fig. 4 is the second schematic diagram of the first embodiment of the calibration device of the present invention; Fig. 5 is the first schematic diagram of the calibration device of the present invention The third schematic diagram of the embodiment. As shown in the figure, the calibration device 1 includes: a first platform 11 , a second platform 12 , a third platform 13 , a control module 14 , a cover 15 , an adjustment part 16 and four resilient pieces 17 . The first platform 11 has three slots 111 , each slot 111 is provided with a positioning module 112 , and each positioning module 112 is composed of a curved body 1121 and a positioning elastic member 1122 . Wherein, the positioning module 112 may be a ball bearing combined with a spring in practical applications. The second platform 12 is disposed on one side of the first platform 11 and has grooves 121 corresponding to the curved surfaces 1121 . Four return springs 17 are disposed between the first platform 11 and the second platform 12 . Each curved surface body 1121 can be a spherical surface or an arc surface, and can be designed according to actual needs. The photosensitive component 10 is placed on the placement plane 123 of the second platform 12 , and the second platform 12 corresponds to the placement plane 123 , and is provided with a plurality of adsorption units 124 , so that the photosensitive unit 10 is flatly attached to the placement plane 123 by means of adsorption. Wherein, the placement plane 123 and the bearing surface 1221 of the bearing portion 122 are parallel to each other. The photosensitive element 10 may be a charge-coupled device (Charge-coupled device, CCD) or a complementary metal-oxide-semiconductor (Complementary Metal-Oxide-Semiconductor, CMOS). The second platform 12 also extends outwards from a supporting portion 122 . The third platform 13 is disposed on the other side of the first platform 11 and is electrically connected to the control module 14 . The cover body 15 has several stitches 151 corresponding to the shape of the photosensitive assembly 10 and uniformly pressed on the photosensitive assembly 10 so that the photosensitive assembly 10 is flat against the placement plane 123 of the second platform 12 . Wherein, the pitch of each stitch 151 may be between 3 cm and the length and width of the photosensitive element 10 . The adjusting part 16 has four working claws 161 , and each working claw 161 abuts against the bearing part 122 of the second platform 12 to displace the second platform 12 in the axial direction. Wherein, the adjustment part 16 may utilize a threaded structure or a gear module to respectively drive the working claws 161 to act. In this embodiment, the threaded structure is used as an example, but the actual application is not limited thereto.

When the photosensitive assembly 10 is placed on the placement plane 123 of the second platform 12, the photosensitive assembly 10 may have an inclination angle with the axis (indicated by a dotted line in the figure). The abutting portion 122 of the second platform 12 is used to adjust the inclination angle between the photosensitive assembly 10 and the axis through the second platform 12 . Moreover, since the placing plane 123 and the abutting surface 1221 are parallel to each other, the inclination angle between the photosensitive assembly 10 and the axis can be adjusted by pushing against the abutting surface 1221 . In addition, during the tilt adjustment process, through the positioning module 112 , the second platform 12 can only be displaced axially without axial rotation.

In detail, when the photosensitive component 10 is placed on the placement plane 123 of the second platform 12, it may form an oblique angle with the axis. The axis is vertical. Since the abutting surface 1221 of the abutting portion 122 of the second platform 12 is parallel to the placing plane 123 , the purpose of adjusting the photosensitive assembly 10 can be achieved by pushing against the abutting portion 122 . When the bearing portion 122 is pushed, the second platform 12 may undergo axial displacement, rotation or both simultaneously. To avoid rotation, the curved body 1121 of the positioning module 112 and the concave surface of the second platform 12 may The slots 121 interact with each other, so that the second platform 12 only moves axially but does not rotate. When the second platform 12 is axially displaced, the first platform 11 and the second platform 12 can be displaced at the same time through several return springs 17, so that the first platform 11 and the second platform 12 maintain a certain distance, thereby avoiding The positioning module 112 is damaged because the distance between the two platforms is too large. In addition, the control module 14 can be used to control the third platform 13 to adjust the photosensitive element 10 to the preset focal plane of the calibration device 1 .

Please refer to Figure 6 and Figure 7 together. FIG. 6 is a first schematic diagram of the second embodiment of the calibration device of the present invention; FIG. 7 is a second schematic diagram of the second embodiment of the calibration device of the present invention. As shown in the figure, the calibration device 1 includes: a first platform 11, a second platform 12, a third platform 13, a control module 14, a cover body 15, an adjustment part 16, a plurality of restoring elastic members 17, a sensing module 18 and Housing 19. The first platform 11 has three cavities 111 . Each of the cavities 111 is provided with a positioning module 112 . Each positioning module 112 includes a curved body 1121 and a positioning elastic member 1122 . The second platform 12 is disposed on one side of the first platform 11 and has three grooves 121 corresponding to each curved body 1121 . Wherein, a plurality of restoring elastic members 17 are disposed between the first platform 11 and the second platform 12 . The second platform 12 also extends outwards from a supporting portion 122 . The photosensitive assembly 10 is placed on the placement plane 123 of the second platform 12 , and passes through several suction units 124 in the second platform 12 to be flatly attached to the placement plane 123 . The third platform 13 is disposed on the other side of the first platform 11 and is electrically connected to the control module 14 . The cover body 15 presses the photosensitive assembly 10 to the second platform 12 through several pins 151 . Wherein, in practical application, the cover body 15 may be a flip cover, and the plurality of pins 151 are arranged on the upper cover of the flip cover corresponding to the photosensitive element 10 . The adjusting part 16 has four working claws 161 , and each working claw 161 pushes against the abutting part 122 to make the second platform 12 move along the axis. The sensing module 18 senses the displacement of the second platform 12 to generate a displacement signal and send it to the control module 14 .

Specifically, when the photosensitive assembly 10 is placed on the placement plane 123 of the second platform 12, the photosensitive assembly 10 may have an inclination angle with the axis (the optical axis of the imaging device), and in order to allow the photosensitive assembly 10 to be correctly arranged in the imaging device , so the photosensitive surface of the photosensitive component 10 needs to be adjusted to be perpendicular to the optical axis. At this time, each working claw 161 of the adjustment part 16 can be used to push against the supporting part 122 of the second platform 12 so that the photosensitive surface is perpendicular to the optical axis. During the pushing process, through the stretching of the positioning elastic member 1122 of the positioning module 112, the curved body 1121 is kept in contact with the groove 121 of the second platform 12 at any time, so that the first platform 11 and the second platform 12 are in the adjustment process. In , only displacement along the axis occurs, no rotation occurs. In addition, it is worth mentioning that when the calibration device 1 is in the initial state (when the second platform 12 is not pushed), the second platform 12 is flat against one side of the first platform 11, in other words, the calibration device 1 is In the initial state, there is no gap between the first platform 11 and the second platform 12, and during the adjustment process, the second platform 12 is pushed away and gradually moves away from the first platform 11. At this time, four return springs can 17. Make the first platform 11 move along with the second platform 12, so as to prevent the positioning module 112 from being damaged due to an excessive gap between the first platform 11 and the second platform 12 during the adjustment process. During the calibration process, the sensing module 18 senses the displacement of the second platform 12 at any time to generate a displacement signal and transmit it to the control module 14 . Wherein, in practical applications, the light-sensing distance measuring module can be used to measure the distance between the second platform 12 and the fixed top cover, so that the actual displacement of the second platform 12 can be measured and inferred. After the adjustment of the photosensitive assembly 10 is completed, the control module 14 can be used to lower the third platform 13 back to the original position according to the displacement signal; Excessive displacement in the opposite direction causes the problem that it cannot be adjusted. The control module 14 can receive and interpret the displacement signal. When the displacement reaches a critical value, the control module 14 controls the third platform 13 to perform reverse displacement to drive the The first platform 11 and the second platform 12 are axially displaced in opposite directions at the same time.
