Referring to fig. 3 and 4, the fixed housing 20 avoids the imaging light to avoid blocking the camera module 40. Specifically, the fixed housing 20 is provided with a housing side avoiding hole 201 for avoiding the imaging light, that is, the housing side avoiding hole 201 is provided for avoiding the light transmitting hole 101 so as to avoid the imaging light between the camera module 40 and the light transmitting hole 101.
Referring to fig. 3 to 4, the positioning bracket 30 is disposed on the fixed housing 20 and coaxially aligned with the light-transmitting structure, and the camera module 40 is disposed on a side of the positioning bracket 30 away from the screen module 10 and coaxially aligned with the positioning bracket 30.

Referring to fig. 1 and 2, in order to make the camera of the camera module 93 coaxial with the screen printing hole 911 of the screen module 91, two side surfaces of the fixed housing 92 are respectively provided with a screen end positioning slot 923 and a camera end positioning slot 922, the camera end positioning slot 922 is provided with a through hole 921 at the bottom thereof, when assembling the camera, the screen module 91 is first installed in the screen end positioning slot 923, then the camera module 93 is installed in the camera end positioning slot 922, the screen end positioning slot 923 and the camera end positioning slot 922 respectively play a role in positioning the screen module 91 and the camera module 93, but because there are installation tolerances between the screen module 91 and the screen end positioning slot 923 and between the camera module 93 and the camera end positioning slot 922 during assembling, the position of the camera center relative to the screen printing hole 911 of the screen module 91 includes the sum of the two tolerances, the camera and the silk screen hole 911 can not be coaxially aligned, so that the shooting effect of the camera is deteriorated, and the user experience is reduced. In the conventional assembly of the screen assembly 91 and the fixed housing 92, although the position of the screen hole 911 on the screen assembly 91 is preset to be opposite to the front housing through hole 921, due to the existence of tolerance, if the edge of the TP is aligned with the edge of the fixed housing 92, the alignment of the screen hole 911 with the through hole 921 on the fixed housing 92 cannot be considered, and if the screen hole 911 and the through hole 921 of the fixed housing 92 are calibrated in advance in order to improve the alignment accuracy of the screen hole 911 and the through hole 921 on the fixed housing 92, the TP and the fixed housing 92 cannot be aligned easily. Meanwhile, because the distance between one side of the camera facing the screen component 91 and one side of the camera facing the screen component 91 is short relative to the distance between one side of the camera facing the screen component 91, the collision between the camera and the screen component 91 is easy to occur when the terminal equipment falls, so that the screen component 91 or the camera component 93 is invalid, and the reliability of the camera device is improved.
In view of the above problems, the present image pickup apparatus mounts the positioning bracket 30 on the stationary housing 20. This camera device is through setting up locating support 30 for the counterpoint of through-hole 921 and the silk screen printing hole 911 on the screen pack 91 becomes locating support 30 and the counterpoint of the light transmission structure of screen pack 10 in this embodiment on the fixed casing 92 among the prior art. Conventionally, adding one more component increases the alignment tolerance of one component, that is, the positioning bracket 30 should cause the alignment precision of the camera module 40 and the light-transmitting structure to be reduced, and in order to ensure the peripheral alignment precision of the fixed housing 20 and the screen module 10, the housing-side avoiding hole 201 of the fixed housing 20 and the light-transmitting hole 101 cannot be coaxially aligned by means of industrial camera calibration and the like. And in this camera device, earlier calibrate the position between locating support 30 and the light-transmitting structure, reduce the tolerance between its and the light-transmitting structure, guarantee after the two axiality with locating support 30 again on installing to fixed casing 20, constitute a new shell structure with locating support 30 in other words, it is accurate not only to have guaranteed the periphery of fixed casing 20 and screen subassembly 10 to counterpoint, also guaranteed the counterpoint precision between locating support 30 and the light-transmitting structure, just so whole reduce the tolerance between camera shooting subassembly 40 and the light-transmitting structure, the counterpoint precision between camera shooting subassembly 40 and the light-transmitting structure has been improved promptly, and then the shooting effect of camera shooting subassembly 40 has been improved. The shapes of the support side avoiding hole 301 and the light transmitting hole 101 may be regular patterns, such as circles, regular polygons, or irregular patterns, and the shapes of the two may be the same. Meanwhile, due to the arrangement of the positioning support 30, the fixed shell 20 is lifted, the axial distance between the camera 42 and the screen assembly 10 is increased, and the condition that the screen assembly 10 or the camera assembly 40 fails due to mutual collision when the camera assembly and the screen assembly fall off due to too small distance between the camera 42 and the screen assembly 10 is avoided.
Referring to fig. 3 and 5, the positioning bracket 30 and the camera module 40 can be mounted by clamping, plugging, fastening, or adhering. In this embodiment, the side of the positioning bracket 30 facing away from the fixing housing 20 is provided with an insertion groove 302, and the camera module 40 is disposed in the insertion groove 302. Optionally, the camera module 40 is inserted into the insertion groove 302 and fixedly connected to the positioning bracket 30 by interference fit, so as to achieve quick alignment and connection between the camera module 40 and the positioning bracket 30. Referring to fig. 6, the image capturing assembly 40 includes a bracket 41 and a camera 42 connected to the bracket 41 and extending toward the light hole 101, wherein when the image capturing assembly 40 is mounted on the positioning bracket 30, the camera 42 is coaxially aligned with the bracket-side avoiding hole 301. Referring to fig. 5 again, the bracket-side avoiding hole 301 is opened at the bottom of the insertion groove 302 to facilitate connection between the camera module 40 and the positioning bracket 30 and alignment between the camera 42 and the bracket-side avoiding hole 301. To prevent the fixed housing 20 and the positioning bracket 30 from blocking the camera 42 from imaging, the camera 42 is inserted into the bracket-side avoiding hole 301 and the housing-side avoiding hole 201 and extends toward the light-transmitting hole 101. Optionally, the cross section of the insertion groove 302 is non-circular, and the bracket 41 is in a shape adapted to the insertion groove 302, so that the camera module 40 is aligned through the insertion groove 302, and the insertion groove 302 limits the camera module 40 to prevent it from rotating.

The calibration space 203 provides a movement space for the positioning frame 30 to translate during the calibration process. In addition, as the positioning bracket 30 is pressed towards the groove bottom of the fixing groove 202, the gap between the shell side calibration plane 204 and the bracket side calibration plane 304 is reduced, when the adhesive 50 is too much, the adhesive 50 is pressed to be thin and spread towards the peripheral side, and overflows to the calibration space 203 between the positioning bracket 30 and the groove wall of the fixing groove 202, the calibration space 203 is used for preventing the adhesive 50 from overflowing to other areas of the fixing shell 20, and simultaneously preventing the adhesive layer from being too thick due to the fact that the adhesive 50 cannot overflow to affect the attachment of the shell side calibration plane 204 and the bracket side calibration plane 304 and the alignment of the positioning bracket 30 and the light transmission hole 101, and preventing the adhesive 50 from overflowing towards the bracket side avoiding hole 301 or the shell side avoiding hole 201 to cause the passing of the shielded imaging light. That is, the fixing groove 202 serves to roughly align the positioning bracket 30 and to limit the area where the adhesive 50 overflows.

S4, assembling the camera assembly 40 to the positioning bracket 30 such that the camera assembly 40 is coaxially aligned with the positioning bracket 30. That is, the camera assembly 40 is inserted into the insertion groove 302 and the camera 42 of the camera assembly 40 is inserted into the bracket-side avoiding hole 301, wherein the camera assembly 40 can move towards the bell mouth 303 so that the camera 42 moves towards the central axis of the bracket-side avoiding hole 301 along the bell mouth 303 until the camera is coaxially aligned with the bracket-side avoiding hole 301.
In the above method, after the support-side calibration plane 304 is attached to the housing-side calibration plane 204 of the fixed housing 20, the support-side calibration plane 304 is radially moved relative to the housing-side calibration plane 204 to align with the central axis of the light-transmitting structure, so that the positioning support 30 can be axially aligned while maintaining the radial direction unchanged, thereby achieving the rapid alignment between the positioning support 30 and the light-transmitting structure and improving the alignment reliability of the positioning support 30. The industrial camera adopts a visual alignment mode to calibrate the position of the positioning support 30, has high alignment precision and sensitivity and strong reliability, and greatly improves the alignment precision between the positioning support 30 and the light-transmitting structure. The camera shooting assembly 40 is coaxially aligned with the support side avoiding hole 301 through the horn mouth 303, and the alignment precision between the camera shooting assembly 40 and the positioning support 30 is improved. Therefore, the assembly method simultaneously reduces the tolerance between the positioning support 30 and the light-transmitting structure and the tolerance between the camera shooting assembly 40 and the positioning support 30, thereby greatly improving the alignment precision between the camera shooting assembly 40 and the light-transmitting structure and further improving the shooting effect of the camera shooting assembly 40.
The present invention is not intended to be limited to the particular embodiments shown and described, but is to be accorded the widest scope consistent with the principles and novel features herein disclosed.
