[0035] The present utility model provides a bottle body detection light source and a vision detection system, which are applicable to the application scenario of visually detecting a to-be-detected bottle body, and can illuminate the bottle body and the bottle top of the to-be-detected bottle body to improve the accuracy of vision detection.

[0036] See Figure 1 and Figure 2 , the vision detection system includes a bottle body detection light source 1 for illuminating the to-be-detected bottle body 100, a camera module for acquiring image information of the to-be-detected bottle body 100, and a conveyor belt 3 for conveying the to-be-detected bottle body 100.

[0037] The bottle body detection light source 1 includes a cylindrical bottle body lighting part 101 and a conical bottle top lighting part 102 located above the bottle body lighting part 101; an avoidance space 103 for the to-be-detected bottle body 100 to pass through is provided at the middle position of both the bottle body lighting part 101 and the bottle top lighting part 102.

[0038] The bottle body detection light source 1 and the vision detection system provided in this embodiment. The conveyor belt 3 sends the bottle body 100 to be detected into the bottle body detection light source 1 through the avoidance space 103. The bottle body lighting part 101 horizontally lights the bottle body of the bottle body 100 to be detected, illuminating the bottle body position of the bottle body 100 to be detected. The bottle top lighting part 102 obliquely downward lights the bottle top of the bottle body 100 to be detected, illuminating the bottle top position of the bottle body 100 to be detected. Then, the camera module can obtain the image information of the bottle body 100 to be detected through the detection hole, and further complete the vision detection operation of the bottle body 100 to be detected.

[0039] Therefore, the bottle body detection light source 1 and the vision detection system provided by the present utility model can light the bottle body and the bottle top of the bottle body 100 to be detected, so as to improve the accuracy of vision detection.

[0040] Optionally, the bottle body detection light source 1 is a structure symmetrically arranged with respect to the avoidance space 103, so as to evenly light the bottle body 100 to be detected from both left and right sides.

[0041] The bottle top lighting part 102 is provided with a longitudinal detection hole 1021 oppositely arranged with the bottle top of the bottle body 100 to be detected, and the bottle body lighting part 101 is provided with a transverse detection hole 1011 oppositely arranged with the bottle body of the bottle body 100 to be detected.

[0042] Correspondingly, the camera module includes a bottle top detection camera 201 located above the bottle body detection light source 1 and a bottle body detection camera 202 located on the side position of the bottle body detection light source 1.

[0043] The bottle top detection camera 201 obtains the image information of the top of the bottle body 100 to be detected downward through the longitudinal detection hole 1021, and the bottle body detection camera 202 horizontally obtains the image information of the bottle body of the bottle body 100 to be detected through the transverse detection hole 1011.

[0044] The bottle body lighting part 101 includes an arc-shaped lamp panel 1012 and an arc-shaped diffusion panel 1013. The arc-shaped lamp panel 1012 irradiates light to the arc-shaped diffusion panel 1013, so that the arc-shaped diffusion panel 1013 emits light evenly, and then evenly illuminates the bottle body position of the bottle body 100 to be detected.

[0045] The bottle top lighting part 102 includes a plurality of inclined lamp panels 1022 with a semi-circular ring structure; each of the inclined lamp panels 1022 is spliced to form a hemispherical light-emitting surface. It should be noted that the manufacturing cost of an integrally structured hemispherical lamp panel is relatively high. The present utility model splices a plurality of inclined lamp panels 1022 with a semi-circular ring structure to obtain a hemispherical light-emitting surface, which can not only realize multi-angle light emission and irradiation, but also reduce the manufacturing cost.

[0046] In summary, the bottle body detection light source 1 and the vision detection system provided in this embodiment have the following advantages:

[0047] ①The light-emitting part 101 of the bottle body emits light horizontally towards the bottle body of the bottle to be measured 100, illuminating the position of the bottle body of the bottle to be measured 100. The light-emitting part 102 of the bottle top emits light obliquely downwards towards the bottle top of the bottle to be measured 100, illuminating the position of the bottle top of the bottle to be measured 100, so as to improve the accuracy of visual detection of the camera module.

[0048] ②The inclined light plates 1022 with multiple semi-circular structures are spliced to obtain a hemispherical light-emitting surface, which can not only realize multi-angle light emission and illumination, but also reduce the manufacturing cost.

[0049] Finally, it should be noted that although the above embodiments have been described in the text and drawings of the specification of the present application, the patent protection scope of the present application cannot be limited thereby. Any technical solutions obtained by equivalent structure or equivalent process substitution or modification based on the substantial concept of the present application and using the content recorded in the text and drawings of the specification of the present application, as well as the technical solutions of the above embodiments directly or indirectly implemented in other related technical fields, are all included in the patent protection scope of the present application.
