Description

Technical Field

[0001] The utility model belongs to the technical field of float glass quality detection equipment, in particular to an online detection device for detecting deformation of glass edges. Background Art

[0002] Float glass is deformed at the edges due to the action of the edge drawing machine gears. This deformed glass must be cut off and cannot be included in the finished glass. Therefore, minimizing the deformation band at the edge of the glass is one of the important means to improve the yield of glass.

[0003] Without a reference object for comparison, it's difficult to visually determine the extent of the deformation band on the glass edge. The traditional testing method involves taking a sample of the glass edge and bringing it to a testing room, where it's placed on specialized testing equipment to examine the level of deformation and the size of the edge. This testing method is not only time-consuming but also wastes glass. Utility Model Content

[0004] The purpose of the utility model is to provide an online detection device for detecting deformation of glass edges, which effectively solves the problem of poor timeliness of current detection methods for deformation bands on glass edges.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0006] An online detection device for detecting deformation of glass edges includes a movable bracket, a light box, and a black and white striped curtain. The bottom wall of the light box is connected to the top of the movable bracket. The light box is in the shape of a rectangular parallelepiped with an open front. The black and white striped curtain is arranged on the front side of the light box and covers the front opening of the light box. The black and white striped curtain is painted with black and white stripes, and the angle between the stripes and the bottom horizontal line of the light box is 45 degrees.

[0007] Furthermore, the light box has multiple LED tubes built in, and the outer surface of the light box is painted black.

[0008] Furthermore, the total brightness of the light box is 1500 lx.

[0009] Furthermore, the black and white striped curtain is made of an acrylic plate, the width of the black stripes on the black and white striped curtain is 25 mm, and the spacing between adjacent black stripes is 25 mm.

[0010] Furthermore, the light box is made of a wooden board, and the movable bracket is in the shape of a cuboid and is made of angle irons welded together.

[0011] Furthermore, the length of the movable bracket is the same as the length of the light box.

[0012] Furthermore, the light box has four built-in LED light tubes.

[0013] Furthermore, a caster is provided at each of the four corners of the bottom of the movable bracket.

[0014] Compared with the prior art, the beneficial technical effects of the present invention are:

[0015] This new system utilizes a combined design of a movable support, a light box, and a black-and-white striped screen. The movable support is moved to the left and right sides of the annealing lehr's F zone, ensuring that the bottom edge of the black-and-white striped screen is at the same height as the glass in the F zone. By observing the reflection of the black-and-white striped screen on the glass and the degree of curvature of the black-and-white stripes in the reflection, the level of glass edge deformation and the size of the edge entry can be determined. This system enables continuous monitoring of the level of glass edge deformation and the size of the edge entry directly on the production line, significantly improving detection efficiency and reducing detection costs.

[0018] Explanation of reference numerals: movable bracket-1; light box-2; black and white striped curtain-3; stripes-4; casters-5. DETAILED DESCRIPTION

[0019] Example 1: Figure 1 and Figure 2 As shown, the online inspection device for detecting glass edge deformation includes a movable bracket 1, a light box 2, and a black and white striped curtain 3. The bottom wall of the light box 2 is connected to the top of the movable bracket 1. The light box 2 is a rectangular parallelepiped with an open front. The black and white striped curtain 3 is fixed to the front side of the light box 2 and covers the front opening of the light box 2. The black and white striped curtain 3 is painted with black and white stripes 4, and the stripes 4 form a 45° angle with the bottom horizontal line of the light box 2.

[0020] In this embodiment, the movable bracket 1 is a rectangular parallelepiped made of 50*50mm welded angle iron. It has a height of 2400mm and a length and width of 1200mm and 500mm, respectively. The light box 2 is made of a 1.5cm thick wooden board and has dimensions of 1200*300*1200mm.

[0021] In this embodiment, the light box 2 has four 18W LED tubes built in, the total brightness of the light box 2 is 1500 lx, and the outer surface of the light box 2 is painted black.

[0022] In this embodiment, the black and white striped curtain 3 is made of an acrylic plate. The width of the black stripes on the black and white striped curtain 3 is 25 mm, and the interval between adjacent black stripes is 25 mm.

[0023] In this embodiment, in order to facilitate the movement of the entire equipment, a caster 5 is provided at each of the four corners at the bottom of the movable bracket 1, and each caster 5 is equipped with a braking device. When the movable bracket 1 is moved to the required position, the braking device is used to lock the caster 5 to prevent the movable bracket 1 from moving.

[0024] The working principle of the present invention is as follows: two online detection devices according to the present invention are respectively placed on the left and right sides of the annealing furnace F zone opposite to each other and slightly offset, with the lower edge of the black and white striped curtain 3 at the same height as the glass on the annealing furnace F zone, and the reflection of the black and white striped curtain 3 on the glass is observed. According to the bending degree of the black and white stripes in the reflection, the level of deformation of the glass edge and the edge entry size can be judged.

[0025] The utility model can continuously monitor the level of glass edge deformation and the edge entry size directly on the production line, greatly improving the detection efficiency and reducing the detection cost.

[0026] Parts not described in the present invention can be realized by adopting or drawing on existing technologies.

[0027] 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 scope of protection of the present invention.
