Abstract
Description
Technical Field
[0001] The utility model relates to the field of glass processing, in particular to a glass detection device. Background Art
[0002] Glass is an amorphous, inorganic, non-metallic material, typically made from a variety of inorganic minerals with a small amount of auxiliary raw materials. Ultra-clear glass panels are used in photovoltaic power generation. Ultra-clear glass is a type of ultra-transparent, low-iron glass, also known as low-iron glass or high-transparency glass. It is a high-quality, versatile, and new premium glass variety with a light transmittance exceeding 91.5%. Traditional defect detection methods use a single light source angle, and the glass moves slowly on a conveyor. Furthermore, since most defects on the glass surface are directional, the detection effect varies for scratches in different directions, making some directions difficult to detect. This reduces the accuracy of glass inspection. Utility Model Content

DETAILED DESCRIPTION
[0019] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.
[0020] In the drawings, the same reference numerals all refer to the same components.
[0021] like Figure 1-3 As shown, the utility model provides a glass detection device, including a base 1, a gantry 2 and a roller conveying mechanism 3. The gantry 2 and the roller conveying mechanism 3 are both arranged on the base 1, and the roller conveying mechanism 3 is located below the gantry 2. A first detection component 4 and a second detection component 7 are respectively provided on both sides of the gantry 2 to detect the glass.
[0022] In this embodiment, the glass to be inspected is sent to the gantry 2 by a roller conveyor mechanism 3 using the prior art, and the glass is inspected by the first inspection component 4 and the second inspection component 7 on the gantry 2;
[0023] The two first detection assemblies 4 and the two second detection assemblies 7 can simultaneously perform defect detection on the two pieces of glass on the roller conveyor mechanism 3 .
[0024] Furthermore, the first detection assembly 4 includes two first electric guide rails 5 and two first detection units 6. The two first electric guide rails 5 are horizontally arranged on one side outer wall of the gantry 2, and the two first detection units 6 are respectively arranged on the moving seats of the two first electric guide rails 5.
[0025] In this embodiment, two first electric guide rails 5 are provided on one side outer wall of the gantry 2 and are at the same height. The two first electric guide rails 5 respectively drive the corresponding first detection units 6 to move horizontally to perform defect detection on the passing glass.
[0026] Furthermore, the first detection unit 6 includes a first electric push rod 61, a first mounting seat 62, a first light source 63 and a first detection camera 64. The first electric push rod 61 is arranged on the moving seat of the first electric push rod 61, and its piston rod is arranged vertically downward. The first mounting seat 62 is arranged at the end of the piston rod of the first electric push rod 61. The first light source 63 and the first detection camera 64 are both arranged on the first mounting seat 62, and the ends of both are arranged vertically downward, and are both located between two adjacent rollers of the roller conveyor mechanism 3.
[0027] In this embodiment, the first electric guide rail 5 can drive the first electric push rod 61 installed on the movable seat to move horizontally. The height of the first mounting seat 62 can be adjusted through the first electric push rod 61, thereby adjusting the height of the first light source 63 and the first detection camera 64. The first light source 63 of the existing technology is used to illuminate the glass passing below with vertical downward light, and then the first detection camera 64 of the existing technology is used to detect defects in the glass. The first detection camera 64 is a CCD camera.
[0028] Furthermore, a second light source 10 is provided at the top of the base 1 , which is located below the roller conveyor mechanism 3 , and the light emitted by the second light source 10 passes obliquely upward between two adjacent rollers of the roller conveyor mechanism 3 corresponding to the first light source 63 .
[0029] In this embodiment, the light emitted vertically downward by the first light source 63 is difficult to illuminate all defects in the glass, so a second light source 10 using existing technology is added to emit inclined light from below the glass to illuminate the bottom end of the glass. The glass is illuminated by the staggered light from the first light source 63 and the second light source 10, thereby improving the accuracy of the first detection camera 64 in detecting glass defects; the second light source 10 is strip-shaped, so as to illuminate the entire piece of glass from one side to the other without moving the light source.
[0030] Furthermore, the second detection assembly 7 includes two second electric guide rails 8 and two second detection units 9. The two second electric guide rails 8 are horizontally arranged on one side outer wall of the gantry 2, and the two second detection units 9 are respectively arranged on the moving seats of the two second electric guide rails 8.
[0031] In this embodiment, two second electric guide rails 8 are provided on one side outer wall of the gantry 2 and are at the same height. The two second electric guide rails 8 respectively drive the corresponding second detection units 9 to move horizontally to detect defects on the passing glass.
[0032] Furthermore, the second detection unit 9 includes a second electric push rod 91, a second mounting seat 92, a third light source 93 and a second detection camera 94. The second electric push rod 91 is arranged on the moving seat of the second electric push rod 91, and its piston rod is arranged vertically downward. The second mounting seat 92 is arranged at the end of the piston rod of the second electric push rod 91. The third light source 93 and the second detection camera 94 are both arranged on the second mounting seat 92 and are both located between two adjacent rollers of the roller conveyor mechanism 3. The ends of the second detection camera 94 are both arranged vertically downward, and the light emitted by the third light source 93 passes obliquely downward between the two adjacent rollers of the roller conveyor mechanism 3 below it.
[0033] In this embodiment, the second electric guide rail 5 can drive the second electric push rod 91 installed on the movable base to move horizontally. The second electric push rod 91 can adjust the height of the second mounting base 92, thereby adjusting the height of the third light source 93 and the second detection camera 94. The third light source 93 of the prior art illuminates the glass passing below with an oblique downward light, and then the second detection camera 94 of the prior art is used to detect defects in the glass. The second detection camera 94 is a CCD camera.
[0034] The angle of the light emitted by the third light source 93 is different from that of the second light source 10, and can illuminate different defects in the glass.
[0035] Furthermore, a fourth light source 11 is provided at the top of the base 1 , which is located below the roller conveyor mechanism 3 , and the light emitted by the fourth light source 11 passes vertically upward between two adjacent rollers of the roller conveyor mechanism 3 corresponding to the third light source 93 .
[0036] In this embodiment, the light emitted by the third light source 93 at an angle upward is difficult to illuminate all defects in the glass, so a fourth light source 11 using existing technology is added to emit vertically upward light from the bottom of the glass to illuminate the bottom end of the glass. The glass is illuminated by the interlaced light from the third light source 93 and the fourth light source 11, thereby improving the accuracy of the second detection camera 94 in detecting glass defects; the fourth light source 11 is strip-shaped, so as to illuminate the entire piece of glass from one side to the other without moving the light source.
[0037] The utility model relates to a glass detection device, which performs two inspections on the glass on a roller conveyor mechanism through a first detection component and a second detection component on both sides of a gantry, and irradiates the glass with light sources of different angles in the first detection component and the second detection component respectively, and then detects defects inside the glass through a visual system, and then combines the two detection results to provide high detection accuracy.
[0038] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
