[0026] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0028] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0029] like Figure 1 and Figure 2 As shown, it includes an industrial camera 1 and a bracket 2. The shooting end of the industrial camera 1 is aligned with the bracket 2 to receive the light reflected from the glass to be tested. A position for placing the glass to be tested is provided on the bracket 2. A light guide bar 3 for illuminating the glass to be tested is provided above the bracket 2. The light guide bar 3 emits a light 7 to illuminate the bracket 2. Glass 4 is placed on the bracket 2. The light guide bar 3 diffusely reflects the light 7 through the glass 4. The light 7 is refracted into the shooting end of the industrial camera 1. The light guide bar 3 diffusely reflects the effective light 7 and shrinks it on the glass 4. Then the effective light 7 is refracted from the glass 4 and shrinks to the shooting end of the industrial camera 1. The industrial camera 1 then cooperates with relevant equipment to feedback the detection results.

[0030] The bracket 2 can be tilted, and the tilt angle of the bracket 2 can be adjusted, so that the glass 4 is tilted on the bracket 2, and the light guide bar 3 emits a light 7 to the glass 4 and the light 7 is reflected from the glass 4 to the shooting end of the industrial camera 1 to form an angle. Light sources 6 are arranged at both ends of the light guide bar 3. In other embodiments, the light source 6 can also be arranged at only one end of the light guide bar 6, and the light source 6 illuminates the light guide bar 3. The light source 6 provides light to the light guide bar 3. The light emitted by the light guide bar 3 is actually the light 7 provided by the diffusely reflected light source 6. The diffusely reflected light 7 of the light guide bar 3 appears dark, so the light 7 will not illuminate the entire background.

[0031] Furthermore, a base plate 5 is provided on the bracket 2, and the base plate 5 is obliquely arranged on the bracket 2. The inclined surface of the base plate 5 faces the shooting end of the industrial camera 1 and the light-emitting end of the light guide strip 3 at the same time. The glass 4 is laid flat on the base plate 5 so that the glass 4 is supported by the base plate 5 to prevent the glass 4 from being easily damaged due to uneven force.

[0032] like Figure 3 and Figure 4 As shown, a first oblique rod 21 and a second oblique rod 22 are movably arranged on the bracket 2. The first oblique rod 21 and the second oblique rod 22 are inclined and the inclination angle is adjustable. The first oblique rod 21 and the second oblique rod 22 are arranged in parallel with a distance from each other, and the base plate 5 is placed obliquely on the first oblique rod 21 and the second oblique rod 22.

[0033] A first blocking piece 23 and a second blocking piece 24 are arranged on the bracket 2 at intervals, and the bottom end of the bottom plate 5 is placed on the first blocking piece 23 and the second blocking piece 24. To prevent the bottom plate 5 from slipping, when the glass 4 is placed on the bottom plate 5, the first blocking piece 23 and the second blocking piece 24 jointly block the glass 4 to prevent the glass 4 from slipping. The first blocking piece 23 and the second blocking piece 24 can also be columns.

[0034] In order to place the glass 4 more stably on the bottom plate 5 , the first blocking piece 23 and the second blocking piece 24 are both bent once, so that the glass 4 and the bottom plate 5 are clamped together by the first blocking piece 23 and the second blocking piece 24 .

[0035] Furthermore, an anti-scratch layer is provided on the upper surface of the bottom plate 5 , and black flocking is used to prevent the surface of the glass 4 from being scratched, and it can also shield the background to prevent the light 7 from illuminating the background.

[0036] like Figure 5 and Figure 6 As shown, multiple light guide strips 3 are arranged to intersect each other vertically and horizontally to form a light strip grid. The ends of multiple light guide strips 3 are connected to a light source 6. The light source 6 uses a safe voltage. In this example, a 12V safety voltage is used. The light guide strips 3 are of a curved light path type. Support columns 33 are provided on adjacent light guide strips 3 to prevent adjacent light guide strips 3 from being close to each other. The support columns 33 allow gaps to exist between adjacent light guide strips 3.

[0037] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with this technology to understand the content of the utility model and implement it accordingly. They cannot be used to limit the protection scope of the utility model. All equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
