Abstract
Description
Technical Field
[0001] The utility model relates to the field of pearl detection, in particular to a visual aid device for pearl luster and halo detection. Background Art
[0002] The pearl industry still follows the previous labor-intensive sorting method, and pearls are divided into multiple grades. At this stage, it mainly relies on experienced workers to grade pearl jewelry. Because gloss and iridescence are important quality characteristics of pearls, sensory inspection is currently carried out through visual methods.
[0003] For example, in the prior art, such as the Chinese patent document with application number CN202310900358.9, a device for detecting pearls is disclosed, which can ensure that no external light enters each time a batch of pearls is detected through the cooperation of a push-up piece, a guide rail and a placement rack. The above patent document discloses a technical solution for visually inspecting pearls, and also solves the problem of external light entering during the visual inspection of pearls through the cooperation of a push-up piece, a guide rail and a placement rack.
[0004] However, the technical solution provided by the above patent document still has limitations in implementation, because the light source it provides is unidirectional and it only detects one quality feature. However, this requires the sample to pass through the detection device again, which increases the working steps and time. At the same time, in specific use, since there are many detection devices that need to be passed, it is impossible to well control the position and irradiation area of the light source applied to the sample each time during implementation. For example, when the sample passes through the latter detection device, the irradiation position of the light emitted by the light source is different from the light irradiation position in the previous detection device. If the light irradiation position in the latter detection device is biased towards the edge of the sample, it is easy to cause sensory errors, resulting in affected detection quality.

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0027] like Figure 1-Figure 3 As shown, the utility model provides a vision aid device for pearl luster and halo detection, comprising:
[0028] A rack 1, which is used to carry samples to be tested;
[0029] Two groups of light source detection groups 2, the two groups of light source detection groups 2 are respectively located on both sides of the sample, the two groups of light source detection groups 2 can simultaneously apply detection light to the sample, and the two groups of light source detection groups 2 are mirror-set with respect to the carrying surface of the placement rack 1 for carrying the sample to be tested so as to guide the detection light applied by each group of light source detection groups 2 to be in the same area;
[0030] The area of the region where each group of detection light rays is located is greater than or equal to the sample area.
[0031] The utility model can realize the action of emitting double light fields in sequence from the same device to simultaneously detect the pearl luster and iridescence by setting two groups of light source detection groups 2. Specifically, the sample is directly placed on the placement rack 1, and then the two groups of light source detection groups 2 are guided to apply detection light to the sample from both sides. When the light is irradiated, since the detection light applied by each group of light source detection groups 2 is in the same area, multiple pearl quality characteristics can be detected without the phenomenon of the light and the position of the sample being offset.
[0032] In the present invention, the sample refers to a combination of multiple arrays of pearls required for detection. Figure 2 , the samples are placed on the supporting surface in a linear array.
[0033] In some specific embodiments, it also includes a body 3 with a delivery port 4 for guiding the sample to the area where the detection light is located. The placement rack 1 and the light source detection group 2 are both fixed in the body 3, and the bearing surface on the placement rack 1 corresponds to the delivery port 4.
[0034] The inlet 4 is used to guide the sample into the central area of the body 3, and then the two light source detection groups 2 can be respectively arranged on the upper and lower sides of the sample.
[0035] In some specific embodiments, the light source detection group 2 includes a detection light area arranged inside the body 3, the detection light area can apply detection light, and a condenser 8 is provided on the side of the detection light area away from the sample.
[0036] In some specific embodiments, the detection light area includes two groups of bead-carrying plates 6 connected to the inner wall of the body 3, there is a gap 9 between the two groups of bead-carrying plates 6, and a detection lamp 5 (usually an LED light strip) is connected to the surface of the bead-carrying plate 6 away from the sample;
[0037] One of the light source detection groups 2 is provided with a window 7, which is located within a spacing 9 within the light source detection group 2. The window 7 can guide the light emitted by the detection lamp 5 to be narrow and long and perpendicular to the sample surface.
[0038] In order to achieve the irradiation of light, the detection lamp 5 is directly guided to emit light. After that, the light corresponding to the empty window 7 is directly irradiated on the sample, and the light that is not irradiated to the empty window 7 will be irradiated on the empty window 7 under the convergence of the condenser 8 (the principle of the condenser 8 to condense light is the same as that of a flashlight) and then irradiated on the sample through the empty window 7, so that the light intensity irradiated on the sample is higher, and the operator can better observe the quality of the pearls when observing.
[0039] At the same time, the light irradiated on the surface of the pearl by the empty window 7 is a horizontal narrow light band.
[0040] In some specific embodiments, based on the height direction of the body 3, the empty window 7 and the top projection of the sample are in the same area. This arrangement is to allow the light to better illuminate the area where the sample is located.
[0041] In some specific embodiments, the length of the window 7 is equal to the length of the carrying surface of the sample to be tested on the rack 1. This arrangement is to ensure that the observation is not limited by the length of the window 7, and the longer length of the window 7 can better guide the light to irradiate the sample.
[0042] In some specific embodiments, there is a set distance between the empty window 7 and the bearing surface, so that light can pass through the viewing area set on the side wall of the body 3.
[0043] This setting is to prevent the viewing area from being blocked. And the setting distance generally needs to meet the distance that the operator can see the pearl sample from the viewing area.
[0044] When the utility model is used, the sample is directly placed on the placement rack 1, and then the two groups of light source detection groups 2 are guided to apply detection light to the sample from the upper and lower sides, that is, the upper and lower groups (each group has two LED light strips) of detection lamps 10 are directly guided to emit light, and then the light corresponding to the empty window 7 is directly irradiated on the sample, and the light that is not irradiated to the empty window 7 will be irradiated on the empty window 7 under the convergence of the condenser 8 and then irradiated on the sample through the empty window 7, so that the light intensity irradiated on the sample is higher, and the operator can better observe the quality of the pearls when observing.
[0045] The above embodiments are only exemplary embodiments of the present application and are not intended to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and protection scope of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present application.
