Description

Technical Field

[0001] This utility model relates to the field of visual inspection equipment, and in particular to a modular light source lens structure. Background Technology

[0002] In current visual inspection, dark or bright surfaces of products are frequently observed, which in turn affects the detection of defects or deficiencies. One factor is the existing light source, such as a surface light source, which mainly distributes light evenly on the surface of the object being inspected. When the object being inspected is a non-standard plane, it is easy to cause localized detection gaps, affecting the inspection results.

[0003] Therefore, the current approach is generally to use a combination of light sources for simultaneous detection or to use multiple sets of light sources for separate detection. Then, the images are compared after noise removal to obtain the detection results. This method involves a large amount of computation and places high demands on the software algorithm.

[0004] Therefore, achieving uniform light coverage on a non-planar surface is the key to the design, thereby improving detection efficiency. Utility Model Content

[0005] The main objective of this invention is to propose a modular light source lens structure, which aims to improve the combination of existing light sources and lenses, thereby increasing the matching degree between light and the detected object, reducing the generation of dark areas, and improving and reducing the image processing steps of the software.

[0006] To achieve the above objectives, this utility model proposes a modular light source lens structure, comprising:

[0007] The carrier has a plurality of spaced-apart prisms on its bottom wall, each prism having an incident light surface, a first irradiation surface, and a second irradiation surface.

[0008] The first and second irradiation surfaces extend beyond the lower wall of the carrier;

[0009] The light-incident surface is horizontally arranged, and two LED beads are arranged at intervals along the length of the light-incident surface above the light-incident surface.

[0010] An illumination area is provided between two adjacent triangular prisms.

[0011] In practical designs, such as new energy batteries, which are generally equipped with an insulating layer, the key to the design is how to develop scratches and thicknesses of the insulating layer. Therefore, by arranging multiple prisms at intervals and setting two LED beads on the same light-incident surface, two sets of light can be simultaneously irradiated in the same irradiation area, thereby avoiding the generation of dark areas and improving the detection effect.

[0012] Of course, in specific testing, the two LED beads can also be combined or set according to actual needs, such as combining red and blue light, white and red light, etc., to achieve different development effects.

[0013] This means that different development effects can be achieved using the same set of light sources, without the need for multiple sets of light sources and multiple images to be combined, thus improving detection efficiency. Attached Figure Description

[0025] like Figures 1 to 3 As shown, a modular light source lens structure includes:

[0026] The carrier 3 has a plurality of spaced-apart prisms 1 on its bottom wall. Each prism 1 has an incident light surface 11, a first irradiation surface 12 (corresponding to light rays 101) and a second irradiation surface 13 (corresponding to light rays 102).

[0027] The first irradiation surface 12 and the second irradiation surface 13 extend beyond the lower wall of the carrier 3;

[0028] The light-incident surface 11 is horizontally arranged, and two LED beads 100 are arranged at intervals along the length of the light-incident surface 11 above the light-incident surface 11.

[0029] An illumination area 2 is provided between two adjacent triangular prisms 1 (the light is superimposed to solve the problem of the existing surface not developing).

[0030] In practical design, for example, new energy batteries are generally equipped with an insulating layer. Therefore, how to develop the scratches and thickness of the insulating layer is the key to the design. By arranging multiple prisms 1 at intervals and setting two LED beads 100 on the same light-incident surface 11, two sets of light can be simultaneously irradiated in the same irradiation area 2, thereby avoiding the generation of dark areas and improving the detection effect.

[0031] Of course, in specific testing, the two LED beads 100 can also be combined or set according to actual needs, such as combining red and blue light, white and red light, etc., to achieve different development effects.

[0032] This means that different development effects can be achieved using the same set of light sources, without the need for multiple sets of light sources and multiple images to be combined, thus improving detection efficiency.

[0033] Specifically, the tilt angle between the first irradiation surface 12 and the second irradiation surface 13 is 45 degrees, which ensures that the light in the irradiation area 2 can be developed, thereby improving the efficiency of visual inspection.

[0034] Specifically, the prisms 1 are spaced apart along the length of the carrier 3, and the first irradiation surface 12 and the second irradiation surface 13 of adjacent prisms 1 are arranged adjacent to each other.

[0035] Of course, specifically, it is possible to achieve the same developing effect using other prisms, such as a pentaprism with all four irradiation surfaces at 45 degrees and four LEDs. Preliminary experiments have shown that the same effect can be achieved. However, compared to the pentaprism setup, the light and the refraction and scattering effects of the prism are not as good as those of a triangular prism.

[0036] In this embodiment of the invention, the included angle between the first irradiation surface 12 and the second irradiation surface 13 is 90 degrees.

[0037] In the first embodiment, the prism 1 is detachable:

[0038] The prism 1 is made of quartz glass and can be detachably installed on the carrier 3.

[0039] Specifically, the carrier 3 is provided with a plurality of through holes 30 spaced apart along its length, the through holes 30 being for placing the triangular prism 1;

[0040] The carrier 3 is provided with pressure strips 31 on both sides along its length. The pressure strips 31 are partially attached to the light incident surface 11, thereby realizing the installation and fixation of the prism 1.

[0041] The pressure strip 31 can be fixed by means of glue, ultrasonic welding, screws, etc.

[0042] Specifically, the through hole 30 is rectangular and the light-incident surface 11 is rectangular, thereby maximizing the light-incident surface 11 and improving the output of the light source.

[0043] Specifically, the through hole 30 has chamfers 32 on at least two sides. The chamfers 32 have the same tilt angle as the first irradiation surface 12 and the second irradiation surface 13, thereby ensuring maximum light refraction efficiency. The chamfers 32 also facilitate the installation of the prism 1. In this embodiment of the invention, the carrier 3 is made of aluminum alloy, which provides better heat dissipation and structural support.

[0044] In the second embodiment, the prism 1 and the carrier 3 are integrally formed by acrylic material, thereby reducing the assembly process.

[0045] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
