Description

Technical Field

[0001] This utility model belongs to the field of float glass testing technology, and in particular relates to a color comparison device and a float glass production line. Background Technology

[0002] Float glass is a crucial basic material in fields such as building curtain walls, automotive glass, photovoltaic modules, and home appliance panels. Its appearance quality and optical properties directly impact the effectiveness of these applications. During the production of float glass, quality inspection typically involves testing the glass's transparency, color, and appearance consistency to ensure that the product meets industry standards and customer requirements.

[0003] Colorimetric testing methods are commonly used in production, with Lab values ​​being a universal color evaluation system. This system quantifies the color and transparency of glass using three parameters: L, a, and b. L represents the lightness of the glass, reflecting its brightness and light transmittance; a represents the red-green axis, characterizing the degree to which the glass leans towards red or green; and b represents the yellow-blue axis, characterizing the degree to which the glass leans towards yellow or blue.

[0004] However, existing testing methods mainly rely on manual visual observation. Since glass is a transparent material, its color difference is often very slight. Manual testing is easily affected by ambient light, observation angle, and the subjective experience of the testing personnel, resulting in unstable and inaccurate test results.

The color comparison device 100 can detect the glass plate 101 prepared by the float glass production line to ensure that the Lab value of the glass plate 101 meets the relevant requirements.

[0021] The color comparison device 100 includes a support assembly 300, a light source assembly 200, a clamping assembly 400, and a colorimeter 500.

[0022] Please see Figures 1 to 3 The support component 300 has a loading surface 303 for placing the glass plate 101. The loading surface 303 is parallel to the horizontal plane and faces upward. The glass plate 101 is erected on the loading surface 303, that is, the height direction of the glass plate 101 is vertical and the thickness direction of the glass plate 101 is horizontal.

[0023] Please see Figures 1 to 3 The light source assembly 200 is connected to the support assembly 300 and located on the carrier surface 303. The light source assembly 200 is used to project light onto the glass plate 101. The projection direction of the light source assembly 200 is parallel to the surface of the glass plate 101. That is, the light source assembly 200 emits light from one end of the glass plate 101 and exits from the opposite end of the glass plate 101.

[0024] Please see Figures 1 to 3The clamping assembly 400 is located on the loading surface 303 and connected to the support assembly 300, and is spaced apart from the light source assembly 200; multiple glass plates 101 are arranged in the horizontal direction, and each glass plate 101 is sequentially attached to the other, and the clamping assembly 400 is used to clamp each glass plate 101; it can be understood that the clamping assembly 400 can clamp and position each glass plate 101, so that the end face of each glass plate 101 remains stable and is located in the same vertical plane, so as to facilitate subsequent color difference detection.

[0025] Please see Figures 1 to 3 The colorimeter 500 is arranged opposite to the light source assembly 200, and each of the glass plates 101 is located between the colorimeter 500 and the light source assembly 200. The colorimeter 500 receives light rays refracted from each glass plate 101 and analyzes the color difference of each glass plate 101 based on the light rays to detect whether the color of the glass plate 101 meets the preparation requirements. It is understandable that when the preparation requirements are relatively relaxed, workers can replace the colorimeter 500 to reduce the cost of the color comparison device 100.

[0026] Please see Figures 1 to 3 The color comparison device 100 provided in this application embodiment supports each glass plate 101 through the support surface 303 of the support component 300, the clamping component 400 stably fixes multiple bonded glass plates 101, and the light source component 200 projects light onto each glass plate 101, so that the colorimeter 500 can detect the color difference of each glass plate 101, realize the quantitative detection of the Lab value of the glass plate 101, ensure the color consistency of each glass plate 101, and keep the color difference fluctuation within the allowable range.

[0027] Please see Figures 1 to 3 Optionally, the colorimeter 500 is an important testing device commonly used to detect whether the color of glass plate 101 is uniform and meets the standards. It illuminates the glass sample with a built-in standard light source and uses a high-sensitivity optical sensor to collect the spectral information of the transmitted or reflected light from the glass. Then, it combines the colorimetric model to calculate the colorimetric value, brightness, and color difference parameters of the glass, thereby achieving accurate quantification and comparison of the glass color.

[0028] Optionally, the dimensions of the support component 300 are 1000mm*360mm*500mm.

[0029] Please see Figures 1 to 3In some embodiments, the clamping assembly 400 includes a first clamp 41 fixed to the loading surface 303, a second clamp 42 slidably disposed on the loading surface 303 and disposed opposite to the first clamp 41, and a drive mechanism 43 for driving the second clamp 42 to move relative to the first clamp 41. The second clamp 42 moves toward the first clamp 41 to clamp each of the glass plates 101, or the second clamp 42 moves away from the first clamp 41 to release each of the glass plates 101.

[0030] Optionally, the stroke range of the second clamp 42 is 0~500mm.

[0031] Optionally, when multiple glass plates 101 are placed between the first clamp 41 and the second clamp 42, the second clamp 42 can be driven towards the first clamp 41 by the drive mechanism 43 to clamp each glass plate 101, and vice versa. This ensures stable positioning and uniform force on the glass plates 101 during the testing process, avoids positional deviations caused by manual fixing, improves the reliability and repeatability of the colorimeter 500 measurement data, and thus enhances the accuracy of float glass color detection.

[0032] Please see Figures 1 to 3 In some embodiments, the first clamp 41 includes a first base plate 412 connected to the loading surface 303 and a first upright plate 411 connected to the first base plate 412, the second clamp 42 includes a second base plate 422 slidably disposed and a second upright plate 421 connected to the second base plate 422, the driving mechanism 43 is connected to the second base plate 422, and the first upright plate 411 and the second upright plate 421 are used to clamp each of the glass plates 101 facing each other.

Protective pads are laid on the surface of the first upright plate 411 facing the glass plate 101 and the surface of the second upright plate 421 facing the glass plate 101. The first upright plate 411 and the second upright plate 421 respectively drive the two protective pads to clamp each glass plate 101 to avoid damage to the glass plate 101.

A handle 434 is provided on the turntable 433, through which the turntable 433 can be driven to rotate.

[0036] Optionally, the drive screw 431 is rotatably connected to the second base plate 422, and drives the second base plate 422 to slide, thereby causing the second upright plate 421 to slide. The sliding direction of the second upright plate 421 is related to the rotation direction of the drive screw 431. By changing the rotation direction of the drive screw 431, the sliding direction of the second upright plate 421 can be changed.

[0037] By applying torque to the turntable 433, the drive screw 431 can be rotated, thereby realizing the reciprocating linear motion of the second vertical plate 421, providing controllable clamping force and position adjustment, and avoiding deformation of the glass plate 101 caused by excessive or insufficient clamping force.

[0040] Please see Figures 1 to 3 It is understandable that the bearing 44 can be installed using an interference fit similar to that between a hole and a shaft. Alternatively, when the second base plate 422 is made of iron, the bearing 44 can be fixedly connected to the second base plate 422 through welding, while the drive screw 431 and the inner ring of the bearing 44 can be connected through an interference fit.

[0041] Please see Figures 1 to 3 In some embodiments, the insertion end of the drive screw 431 is provided with an annular groove 435 located in the insertion hole, and the wall of the insertion hole is provided with a limiting member 45 protruding into the annular groove 435.

The limiting member 45 is a bolt, which is screwed into the threaded hole and partially located in the annular groove 435. It is arranged at intervals with the bottom of the annular groove 435 to achieve axial limiting of the drive screw 431, prevent the drive screw 431 from falling off or loosening, and improve the structural reliability and safety of the clamping assembly 400.

[0043] Optionally, the loading surface 303 is provided with a clearance groove or a hollowed-out design at the position corresponding to the limiting member 45, so as to avoid interference between the limiting member 45 and the loading surface 303.

[0044] Please see Figures 1 to 3 In some embodiments, the color comparison device 100 further includes a guide rail 46 laid on the carrier surface 303 and connected to the support assembly 300, and the second clamp 42 is slidably connected to the guide rail 46.

[0045] Optionally, two guide rails 46 are arranged at intervals, and the drive screw 431 is located between the two guide rails 46. The two ends of the second base plate 422 are slidably connected to the two guide rails 46 respectively. The two guide rails 46 can realize the smooth sliding of the second base plate 422, reduce the sliding resistance and ensure the accuracy of the sliding trajectory, and improve the efficiency and stability of the clamping operation.

[0046] Optionally, the second base plate 422 can be raised by the two guide rails 46, so that there is a certain gap between the limiting member 45 and the loading surface 303, and interference between the loading surface 303 and the limiting member 45 is avoided.

[0047] Please see Figures 1 to 3 In some embodiments, the support assembly 300 includes a support plate 302 having the loading surface 303 and support columns 301 connected to the support plate 302, wherein a plurality of support columns 301 are arranged at intervals.

[0048] Optionally, the loading surface 303 and the support column 301 are located on two opposite surfaces of the support plate 302. The support plate 302 can be placed on the ground through the support column 301 to achieve the horizontal arrangement of the loading surface 303. In this embodiment, four support columns 301 are arranged, and the four support columns 301 are located at the four right angles of the support plate 302.

[0049] Please see Figures 1 to 3 In some embodiments, the light source assembly 200 includes a lamp housing and a light-emitting panel disposed within the lamp housing, the light-emitting panel projecting light toward the glass plate 101.

[0050] Please see Figures 1 to 3Optionally, by designing the light source assembly 200, including the lamp housing and the light-emitting panel, uniform parallel light projection onto the glass plate 101 can be achieved, further improving illumination consistency and brightness control, enhancing the accuracy of the colorimeter 500 in capturing transmitted light, and avoiding color deviation caused by uneven illumination, thereby enhancing the reliability and efficiency of Lab parameter quantification in float glass testing.

[0053] The color comparison device 100 can detect the Lab value of glass sheets 101 produced on the float glass production line, effectively identifying color differences between different batches of glass sheets 101. This ensures color consistency of glass sheets 101 in large-scale production and prevents color variations from affecting product performance. Simultaneously, the Lab value test results provide customers with a reliable basis for quality judgment and can be combined with light transmittance indicators to assist in evaluating the optical performance of the glass, such as whether high-transmittance glass, low-iron glass, or special colored glass meet standards.
