[0002] Prism reflection modules provide an optical component that can efficiently and flexibly reflect and converge light in multiple directions, and are widely used in lighting systems, optical displays, optical communications, optical sensing and solar energy collection systems.

[0003] In traditional optical design, a single mirror or lens group is usually used to reflect and guide light.

[0004] Traditional optical inspection equipment uses three cameras, three prism modules, and three light sources to simultaneously inspect the dispensing status on three sides of a product. The cameras and prisms need to be relatively perpendicular, and the positional accuracy between the cameras is critical, making setup difficult within a limited space. Therefore, we propose a solution to address these technical problems. Utility Model Content

[0020] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution, its main features are:

[0021] This device combines multiple reflectors at a certain angle to form a prism module, and designs a central through hole at the top of the prism module.

[0035] Please see Figures 1 to 7 This utility model embodiment provides a multi-directional prism reflection module, including:

[0036] The module base 1 is in the shape of a through frustum, and multiple mirror mounting slots 12 are provided on its inner side. The multiple mirror mounting slots 12 are sealed together end to end. Multiple mirrors 2 are fixedly installed on the inner side of the mirror mounting slots 12. The multiple mirrors 2 are sealed together end to end.

[0037] Connecting seat 3 is fixedly installed on the top of module base 1, and multiple loading holes 4 are provided through the connecting seat 3;

[0038] The limiting seat 5 is fixedly installed on the top of the connecting seat 3, and an installation groove 6 is provided on its inner side. An arc groove 7 is provided through the limiting seat 5 at the corner of the installation groove 6.

[0039] Penetrating seat 9 is located inside the mounting slot 6;

[0040] In use of this device, the module base 1 is used to load and limit the reflector 2. Since the module base 1 is in the shape of a through frustum, it ensures that the reflective effect is not missing during use. The multiple reflector mounting slots 12 opened on its inner side are used to load the reflector 2. In this embodiment, there are eight reflector mounting slots 12, and there are also eight sets of reflectors 2 on their inner side. The multiple reflector mounting slots 12 are sealed end to end to ensure the integrity of the light source projection and avoid light leakage. The multiple reflectors 2 are fixedly installed on the inner side of the reflector mounting slots 12. Specifically, with the use of eight sets of optical devices, the reflectors 2 can enhance the light source and make the camera area clearer. The multiple reflectors 2 are sealed end to end.

[0041] The connecting seat 3 is used to connect to the module base 1, thereby facilitating the loading of the connecting seat 3 on the module base 1. The connecting seat 3 is fixedly set on the top of the module base 1, and the multiple loading holes 4 through the connecting seat 3 are used to facilitate the fixing and loading of this device.

[0042] The limiting seat 5 is used to connect with the connecting seat 3. The mounting groove 6 opened on the inner side of the limiting seat 5 is used to load the penetrating seat 9. The arc groove 7 opened through the corner of the limiting seat 5 and located at the mounting groove 6 is used to cooperate with the loading and limiting of the penetrating seat 9.

[0043] Light is projected through the penetrating seat 9;

[0044] By combining multiple reflectors 2 at a certain angle to form an integrated prism module, and designing a central through hole at the top of the prism module, a combination of a camera and a light source is used to achieve visual inspection of the top and sides of the target. This achieves multi-faceted inspection while reducing space layout and investment costs. The structure is simple and reliable. The camera module is kept relatively perpendicular to the reflectors 2, which improves the positional accuracy between the camera modules and reduces the difficulty of debugging in a limited space.

[0045] The original machine design can meet the inspection requirements of the original products without changing the original design. The integrated design greatly reduces the installation space and motor load. The inspection position can be adjusted by simply adjusting the height and rotation angle of the prism module. The motor is a mature existing technology and will not be discussed in detail in this article.

[0046] By using only one camera in conjunction with this device, the images reflected by each prism have different distortions, and distortion calibration is performed on the images of each reflecting surface.

[0047] Please see Figure 5 Multiple positioning holes 11 are provided on the module base 1 and on the outside of the reflector mounting slot 12, and the multiple positioning holes 11 are arranged in a ring.

[0048] When this device is in use, multiple positioning holes 11 are provided on the module base 1 and located on the outside of the reflector mounting slot 12 for connection with the connecting seat 3. Since the multiple positioning holes 11 are arranged in a ring, the stability of the two after installation can be guaranteed, so that they are evenly stressed during use.

[0049] Please see Figure 4 The arc groove 7 is connected to the positioning hole 11;

[0050] When this device is in use, since the arc groove 7 is connected to the positioning hole 11, it is convenient to install screws or fill sealant during the connection between the limit seat 5 and the module base 1.

[0051] Please see Figure 7 Multiple connecting grooves 8 are provided on the arc groove 7. The multiple connecting grooves 8 are arranged in a ring and are connected to the positioning hole 11.

[0052] When this device is in use, multiple connecting slots 8 opened on the arc groove 7 are used for the connection between this device and the camera module. The camera module is a mature existing technology and will not be described in detail in this article. The multiple connecting slots 8 are arranged in a ring to ensure uniform installation and make the seal between this device and the camera module uniform.

[0053] Please see Figure 3 and Figure 5 The perimeter of the bottom edge of the penetrating seat 9 is less than the perimeter of the bottom edge of the polygonal prism formed by the sealing splicing of multiple reflectors 2 end to end.

[0054] When this device is in use, since the perimeter of the bottom edge of the penetrating seat 9 is smaller than the perimeter of the bottom edge of the polygonal prism formed by the sealing and splicing of multiple reflectors 2, the light source can be evenly irradiated onto the reflector 2 when passing through this device, thus ensuring the supplementary lighting effect of this device.

[0055] Please see Figure 6 The center of the bottom edge of the penetrating seat 9 and the center of the bottom edge of the polygonal prism formed by the sealing splicing of multiple reflectors 2 are on the same axis;

[0056] When this device is in use, since the center of the bottom edge of the penetrating seat 9 and the center of the bottom edge of the polygonal prism formed by the sealing and splicing of multiple reflectors 2 are on the same axis, the center line of the camera module can be aligned with the center line of this device, thereby facilitating the uniformity of the light source and improving the lighting effect.

[0057] Please see Figure 5 The penetrating seat 9 has a rectangular structure, and a penetrating groove 10 is provided in the center of the penetrating seat 9;

[0058] When this device is in use, the through slot 10 opened in the center of the through slot 9 is used for the extension of the camera module, which helps to reduce the exposure of the light source.

[0059] Please see Figure 5 The through groove 10 has a rectangular slotted structure.

[0060] Please see Figure 5 The bottom side of the penetrating seat 9 is in contact with the top surface of the module base 1.

[0061] Please see Figure 5 The limiting seat 5 is a through cylinder;

[0062] When this device is in use, the through cylindrical limiting seat 5 facilitates the loading of the through seat 9. The limiting seat 5 provides pre-installation space for the through seat 9.

[0063] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the principles of the present utility model should be included within the protection scope of the present utility model.
