Description

Technical Field

[0001] This utility model relates to the field of cosmetic appearance inspection technology, specifically a camera motion module for cosmetic appearance inspection. Background Technology

[0002] Currently, during the production process of cosmetic packaging tubes, it is necessary to test the product quality of the packaging tubes to avoid defects in the packaging tubes that could affect product quality.

[0003] Current cosmetic appearance inspection mainly relies on industrial CCD cameras with a single ring light source, which has significant drawbacks: 1) Axial illumination from a single light source leads to the loss of details in the reflective areas of the bottle; 2) Motion blur occurs due to insufficient frame rate during motion detection; 3) Complex curved surfaces require multiple adjustments of the light source angle to achieve complete imaging. Utility Model Content

[0004] The purpose of this invention is to provide a camera motion module for cosmetic appearance inspection, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a camera motion module for cosmetic appearance inspection, comprising a mounting plate, wherein the upper and lower ends of the mounting plate are fixedly connected by connecting columns, and a light source module is provided at the front end of the mounting plate, and a camera mounting seat is provided on the rear side of the mounting plate, and a camera module is fixed to the top of the camera mounting seat by bolts.

[0006] Furthermore, the light source module consists of two sets forming a dual asymmetric light source, with one set of light source modules being 30° low-angle diffuse light and the other set of light source modules being 60° polarized directional light.

[0007] Furthermore, the illumination surface of the light source module forms a collaborative illumination area, and the illumination surface of the camera module forms a camera field of view area. The camera field of view area and the collaborative illumination area work together to achieve visual inspection of the appearance of cosmetics in a clamped and rotating state.

[0008] Furthermore, the mounting plate is bolted to the top of the connecting seat, and the connecting seat slides along the length of the machine body.

[0009] Furthermore, a motor is provided on the side of the machine body, and the rotating end of the motor is connected to a lead screw via a synchronous belt drive, and the lead screw is threadedly engaged with the connecting seat.

[0010] Furthermore, the body is bolted to the top of the mounting base, and the mounting base is fixedly connected to the bottom of the mounting base around the perimeter.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. In use, this utility model achieves dynamic compensation through the collaborative design of a camera module and a dual asymmetric light source module. One set of light source modules uses 30° low-angle diffused light to highlight surface texture features, while the other set of light source modules uses 60° polarized directional light to suppress reflections in specific wavelengths. The camera module and the light source module are pulse-synchronized, and visual inspection of the cosmetic appearance is achieved under the cooperation of the camera's field of view and the collaborative illumination area, while the cosmetic is held in a rotating state. In this way, diffuse reflection and polarized light data are acquired simultaneously in a single scan. This structure not only improves the efficiency of cosmetic appearance inspection, but also significantly improves the accuracy of identifying reflective interference areas. It is particularly suitable for the inspection of foundation bottles containing pearlescent powder. Attached Figure Description

One set of light source modules 3 is a 30° low-angle diffuse light, and the other set of light source modules 3 is a 60° polarized directional light. Dynamic compensation is achieved through the collaborative design of the camera module 6 and the dual asymmetric light source modules 3. One set of light source modules 3 uses 30° low-angle diffuse light to highlight surface texture features, and the other set of light source modules 3 uses 60° polarized directional light to suppress reflection in specific wavelength bands. The camera module 6 and the light source module 3 are pulse-synchronized.

The camera field of view 7 and the cooperative illumination area 4 cooperate to realize the visual inspection of the appearance of the cosmetics in the clamping and rotating state. The mounting plate 1 is bolted to the top of the connecting seat 8, and the connecting seat 8 slides along the length of the machine body 9. The side of the machine body 9 is equipped with a motor 10, and the rotating end of the motor 10 is connected to a lead screw 11 through a synchronous belt drive. The lead screw 11 is threaded with the connecting seat 8. The machine body 9 is bolted to the top of the fixing seat 12, and the bottom of the fixing seat 12 is fixedly connected with support feet 13.

[0019] Working principle: Dynamic compensation is achieved through the collaborative design of camera module 6 and dual asymmetric light source modules 3.
