Technical Field
[0001] The utility model belongs to the technical field of glass quality control, and in particular relates to an off-line glass defect detection device. Background Art
[0002] In daily glass production, the detection of glass defects usually relies on online glass defect detection equipment, but the detection accuracy of online glass defect detection equipment is generally around 0.3mm, that is, defects larger than 0.3mm will be detected, while defects smaller than 0.3mm will be missed. However, current customers require that the size of glass defects be controlled below 0.1mm, so online glass defect detection equipment cannot meet customers' requirements for glass quality.

[0006] The surface of the back plate in contact with the glass to be inspected is black. The movable baffle includes a vertical frame, a light strip and a shading plate for gathering light. The shading plate is movably connected to the vertical frame. The light strip is fixed to the vertical frame on the rear side of the shading plate.
[0007] Furthermore, the width of the shading plate is 15-20 cm.

[0011] Furthermore, the width of the back plate is smaller than the width of the glass to be inspected.
[0012] Furthermore, a universal wheel is provided at the bottom end of the base.
[0013] Compared with the prior art, the beneficial technical effects of the utility model are:
[0014] The utility model is based on the principle of glass edge light detection. When light is irradiated from the edge of the glass, tiny glass defects are magnified, and all glass defects larger than 0.1mm will be detected, which is conducive to controlling the size of glass defects below 0.1mm, solving the problem of insufficient detection accuracy of online glass defect detection equipment and meeting customers' requirements for glass quality. BRIEF DESCRIPTION OF THE DRAWINGS
[0015] Figure 1 It is the front view of the utility model.
[0016] Figure 2 It is a side view of the utility model. DETAILED DESCRIPTION
[0017] A glass defect offline detection device, such as Figure 1 and Figure 2 As shown, it includes a square base 1 and a square glass support frame 2, wherein the glass support frame 2 is connected to the base 1 and the angle between the glass support frame 2 and the base 1 is an acute angle. In this embodiment, the angle between the glass support frame 2 and the base 1 is 84°. In order to improve the stability of the connection between the glass support frame 2 and the base 1, a support rib 3 is provided between the glass support frame 2 and the base 1, and the two ends of the support rib 3 are respectively connected to the crossbeams of the glass support frame 2 and the base 1, thereby forming a stable triangular structure. Furthermore, in this embodiment, two support ribs 3 are provided, and the two support ribs 3 are respectively provided on the crossbeams on the left and right sides of the base 1.
[0018] The glass support frame 2 includes two slide rails 4, a back plate 5 for placing the glass to be inspected, and two movable baffles 6 slidably connected to the slide rails 4. The two slide rails 4 are respectively located at the upper and lower ends of the back plate 5, and the two movable baffles 6 are respectively located at the left and right sides of the back plate 5, and the movable baffles 6 can slide left and right along the slide rails 4. In this embodiment, the back plate 5 is arranged in the middle of the glass support frame 2. In this embodiment, preferably, in order to facilitate the operation of the workers, a handle 11 is provided on the movable baffle 6.
[0019] The movable baffle 6 includes a vertical frame 7, a light strip (not shown) and a visor 8 that can move forward and backward for gathering light. The visor 8 is movably connected to the vertical frame 7 by a hinge. The light strip is arranged on the vertical frame 7 and is located at the rear side of the visor 8. The width of the visor 8 is preferably 15-20 cm. Although the width of the visor 8 is larger, the shading effect is better, but the glass part covered by the visor 8 is not visible, and it is impossible to judge whether the glass part covered by the visor 8 has defects. When the glass to be inspected is placed on the glass support frame 2 against the back plate 5, the movable baffles 6 on the left and right sides of the glass to be inspected are moved, so that the light strip is close to the edge of the glass to be inspected, and then the visor 8 is attached to the front surface of the glass to be inspected, so that the light will not be scattered, and the light gathering effect is achieved, so that the light can be as much as possible into the glass to be inspected.
[0020] The surface of the back plate 5 in contact with the glass to be inspected is black, and the width of the back plate 5 is smaller than the width of the glass to be inspected. In this embodiment, the back plate 5 is a galvanized plate, and the surface of the back plate 5 in contact with the glass to be inspected is pasted with black velvet 9. Furthermore, the surface colors of the base 1 and the glass support frame 2 are both black.
[0021] In order to facilitate the movement of the glass defect offline detection device, universal wheels 10 are provided at the bottom ends of the four angles of the base 1 , and a locking device is provided on the universal wheels 10 .
[0022] The working process of the utility model is as follows: the utility model is placed in a dark room, the glass to be inspected is placed close to the back plate 5 on the glass support frame 2, the movable baffles 6 on the left and right sides of the glass to be inspected are moved to make the light strip close to the edge of the glass to be inspected, and then the shading plate 8 is adjusted to make the shading plate 8 close to the front surface of the glass to be inspected, so that the light can shine into the glass to be inspected as much as possible. After being irradiated by the light strip, the defects of the glass to be inspected are very clear, and then the size of the glass defects is checked, and defects smaller than 0.1mm are not counted.
[0023] The utility model is based on the glass edge light detection principle. When light is irradiated from the edge of the glass, tiny glass defects are magnified, and all glass defects larger than 0.1mm will be detected, thereby solving the problem of insufficient detection accuracy of online glass defect detection equipment and meeting customers' requirements for glass quality.
[0024] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
