Referring to fig. 1 to 3, the present invention provides a prism adjusting position calibration mechanism, which includes: the camera module includes a frame 100, and a prism assembly, a camera assembly, and a support plate adjustment assembly provided in the frame 100.
The frame body 100, the frame body 100 has a cavity 102 penetrating along the length direction of the frame body 100; a support plate 200 is disposed within the chamber 102 along the length of the chamber 102.
The prism assembly comprises a prism support frame 202 arranged on the support plate 200 and a prism 204 arranged on the prism support frame 202. The prism support frame 202 is provided with a first opening 203 corresponding to the bottom end surface of the prism 204.

The frame 100 is provided with second openings 208 corresponding to the top and bottom surfaces of the prism 204, respectively. The second opening 208 of the frame 100 corresponding to the bottom end surface of the prism 204 is connected with the first opening 203. The first opening 203 and the second opening 208 are both for the intake of the light beam. The camera 207 of the present embodiment is coupled to a display such that the reticle image is displayed through the display.
The support plate adjusting assembly comprises a rotary connector arranged at one end of the support plate 200 and connected with the top wall surface of the inner cavity of the frame body 100, a connecting block 301 arranged at the other end of the support plate 200 along the width direction of the support plate 200, and a pair of connecting plates 303 respectively arranged on the inner side wall of the cavity 102 at two sides corresponding to the width direction of the connecting block 301; both lateral ends of the connection block 301 in the width direction are rotatably connected to a pair of connection plates 303, respectively. A pair of connecting plates 303 are provided with strip-shaped through grooves 305 along the height direction of the cavity 102; guide shafts 307 adapted to be inserted into the through grooves 305 are provided in the connecting plate 303 at the corresponding through grooves 305.
Specifically, the rotary connector of the present embodiment includes a first connecting frame 308 fixedly connected to the support plate 200, a second connecting frame 309 fixedly connected to a top wall surface of the inner cavity of the frame body 100, and a first center-oriented knuckle bearing 310 disposed between the first connecting frame 308 and the second connecting frame 309. Both lateral ends of the connection block 301 in the width direction are rotatably connected to the connection plate 303 through second pivot joint bearings 312, respectively.

More specifically, the through grooves 305 on the pair of connection plates 303 are symmetrically arranged.
In order to avoid the guide shaft 307 from moving along the through groove 305 under the action of gravity of the prism 204 and the camera 207 itself, the outer diameter of the guide shaft 307 is equal to the inner diameter of the through groove 305, that is, when the guide shaft 307 needs to move along the through groove 305, pressure needs to be applied from the outside so that the guide shaft 307 can move.
In order to allow the support plate 200 to be displaced longitudinally within the cavity 102, a gap exists between the support plate 200 and the bottom wall surface of the cavity 102.
In order to facilitate the alignment adjustment of the position of the prism 204, the end surface of the cavity 102 opposite to the camera 207 corresponding to the prism 204 is provided with a shielding plate 313 detachable from the frame 100. That is, in a normal state, when the position of the prism 204 does not need to be adjusted, the shielding plate 313 is connected to the frame 100 of the end surface of the prism 204 opposite to the camera 207, and when the position of the prism 204 needs to be adjusted, the shielding plate 313 is removed.
In this embodiment, a lamp panel structure is disposed at the outer edge of the second opening 208; the lamp panel structure includes an annular LED lamp 401, and a refractive panel 412 disposed on the outside of the LED lamp 401 facing away from the prism 204. Specifically, the second openings 208 of the frame body 100 corresponding to the top and bottom surfaces of the prism 204 are used for respectively normalizing the incidence of the beams of the cross center line on the product and the jig. The light emitted by the LED lamp 401 is focused through the refraction plate 412, so that an infinitely distant cross center line under dark background is generated at the cross center line of the standardized product and the jig and is used for target aiming. The prism 204 reflects the light beams at the cross center lines of the standardized product and the jig into the camera 207, and forms a corresponding bright cross line image on the display, i.e. whether the cross center lines of the standardized product and the jig coincide can be compared. If the prism 204 is coincident, the current position of the prism is consistent with the use requirement. If the prism 204 cannot be overlapped, the current position of the prism 204 needs to be adjusted.
The specific implementation manner of the prism adjusting position calibration mechanism in this embodiment is as follows: a bolt is inserted into a pair of through grooves 305 at the same time, the guide shafts 307 are adjusted upwards or downwards, so that the guide shafts 307 move downwards or upwards along the through grooves 305, in the moving process, the support plate 200 can rotate around the second centering knuckle bearing 312 through the cooperation of the first centering knuckle bearing 310 and the second centering knuckle bearing 312, further, the support plate 200 generates upward or downwards displacement, in the displacement process, the position of the prism 204 can be adjusted, in the adjustment process, the cross center lines of the jig and the standardized product in the display are continuously observed, whether the jig and the standardized product are overlapped or not is observed, and when the jig and the standardized product are overlapped, the position of the prism 204 is adjusted to be in place.
