Description

Technical Field

[0001] This utility model belongs to the field of glass appearance inspection technology. Specifically, this utility model relates to a device for appearance inspection of ultra-thin grooved glass. Background Technology

[0002] Non-uniform thickness ultra-thin grooved glass (UFG) cover plates offer better bending performance and panel strength compared to ultra-thin glass (UTG). However, the production and processing of non-uniform thickness ultra-thin grooved glass (UFG) cover plates have higher processing and manufacturing requirements, and visual inspection of ultra-thin grooved glass (UFG) is also crucial during the manufacturing process. (See attached diagram in the instruction manual.) Figure 3 As shown, ① is the grooved area, with a thickness typically of 30-40 μm; ③ is the non-grooved area, with a thickness varying from 70-160 μm; ② is the transition zone between ① and ③. During the manufacturing process of UFG glass, the acid etching rate and time of the grooved area ① are controlled to create a thickness difference between the grooved area ① and the non-grooved area ③, thus meeting the manufacturing requirements for grooving in ultra-thin glass. However, the quality and appearance of the transition zone ② of the grooved glass have relatively high requirements. Since the overall thickness of grooved glass is generally thin, it is difficult for the human eye to directly observe and inspect it effectively, making it impossible to accurately identify the location of the transition zone ② and to assess its relevant appearance quality requirements.

[0003] Chinese patent (publication number: 102901418B) discloses a testing device and method for a glass guide channel in a vehicle door assembly. The testing device includes a testing rod whose axial distance is equal to the front-to-back distance of the glass guide channel. The rod is placed horizontally within the glass guide channel and moves up and down between its upper and lower stops to test the front-to-back distance. However, testing with the testing rod yields inaccurate results. Utility Model Content

[0004] This invention addresses the aforementioned problems and aims to provide a device for inspecting the appearance of ultra-thin grooved glass, capable of detecting the quality of the groove transition zone in the grooved glass.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a device for surface inspection of ultra-thin slotted glass, comprising a projection platform, a fixed platform and a detection structure disposed on the projection platform, the glass to be inspected being disposed on the fixed platform, and the detection structure being directly opposite the fixed platform.

[0006] The detection structure includes a support base, which is mounted on a projection platform and has a scattering point light source.

[0007] The support base includes a first support plate, which is disposed on the projection platform. A first fixing plate is connected to the top of the first support plate, and a first mounting plate is connected to one end of the first fixing plate. A second mounting plate is connected to the first mounting plate. The first and second mounting plates have mounting grooves that match the scattering point light source. The scattering point light source is disposed between the first and second mounting plates.

[0008] The fixed platform includes a fixed base, which is set on the projection platform. A limiting plate is provided on the fixed base, and a glass stage is provided on the limiting plate. The glass to be tested abuts against the limiting plate.

[0010] The projection platform includes a base plate, on which partition lines are evenly distributed.

[0011] The limiting plate has a limiting groove.

[0012] The base plate is a one-piece molded ivory whiteboard structure.

[0013] The technical advantages of this invention are as follows: During use, the glass to be tested is placed on the stage and fixed between two limiting plates to prevent displacement. The scattered point light source provides effective and stable scattered light, which passes through the stage and projects onto the base plate. The partition lines on the base plate provide reference coordinates for the testing personnel, facilitating accurate recording and analysis of the glass's position during the testing process, and measurement and testing of the transition zone of the glass groove.

[0019] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention, and to facilitate its implementation.

[0020] like Figures 1-2 As shown, an apparatus for surface inspection of ultra-thin grooved glass includes a projection platform 1, a fixed platform 2, and a detection structure 3. The glass to be inspected is placed on the fixed platform 2, and the detection structure 3 faces the fixed platform 2. The detection structure 3 emits stable scattered light, which projects onto the glass to be inspected. The fixed platform 2 provides a placement position for the glass to be inspected. The scattered light emitted by the detection structure 3 illuminates the glass to be inspected, and the point light source illuminates the grooved area of ​​the glass to be inspected, forming a corresponding projection on the projection platform 1. The shape and defects of the ultra-thin grooved glass are magnified through light and shadow, making it easy for the human eye to observe directly.

[0021] The detection structure 3 includes a support base 31, which is mounted on the projection platform 1. A diffused light source 301 is mounted on the support base 31. The support base 31 is bolted to the projection platform 1, and the diffused light source 301 is positioned directly facing the glass to be inspected for easy inspection. The diffused light source 301 provides effective and stable diffused light for projecting onto the ultra-thin grooved glass. The diffused light source 301 has functions for focus adjustment and slide installation and replacement. Focus adjustment allows for adjustment of the projected size of the glass, adjusting the focus according to the type of glass and the differences in the grooved area to achieve a suitable observation position. Different colored slides provide different colors of diffused light, which can be used to indicate defects according to different conditions.

[0022] The support base 31 includes a first support plate 311, which is disposed on the projection platform 1. A first fixing plate 312 is connected to the top of the first support plate 311. A first mounting plate 302 is connected to one end of the first fixing plate 312. A second mounting plate 303 is connected to the first mounting plate 302. The first mounting plate 302 and the second mounting plate 303 have mounting grooves that match the diffused point light source 301. The diffused point light source 301 is disposed between the first mounting plate 302 and the second mounting plate 303.

[0023] The first support plate 311 of the support base 31 is fixed to the projection platform 1 by bolts. The top of the first support plate 311 is connected to the first fixing plate 312 by welding. The first mounting plate 302 is connected to the first fixing plate 312 by welding. The second mounting plate 303 is connected to the first mounting plate 302 by bolts. The first mounting plate 302 and the second mounting plate 303 are provided with mounting grooves that match the diffused point light source 301. After the diffused point light source 301 is located in the mounting groove, the first mounting plate 302 and the second mounting plate 303 are fastened together by bolts. The diffused point light source 301 is fixed, ensuring that the light source is installed firmly. At the same time, when disassembly and maintenance are required, the bolts can be loosened and the diffused point light source 301 can be removed, which is convenient to use.

[0024] The fixed platform 2 includes a fixed base 21, which is set on the projection platform 1. A glass stage 201 is set on the fixed base 21. The size of the glass stage 201 matches the size of the glass to be tested. When the glass to be tested is placed on the glass stage 201, it can be completely covered before measurement can begin, saving time as there is no need to spend time positioning the glass to be tested. Limiting plates 202 are set at both ends of the glass stage 201. The limiting plates 202 are connected to the fixed base 21. The limiting plates 202 are provided with grooves that match the glass stage 201. The two sides of the glass stage 201 are fixed in the grooves, and the glass to be tested abuts against the limiting plates 202. The mounting base 21 is used to connect to and fix the glass stage 201. The glass to be tested is placed on the glass stage 201. Two limiting plates 202 are provided. The glass to be tested is fixed between the two limiting plates 202 to prevent the glass from shifting. The scattering point light source 301 can provide effective and stable scattered light. The light passes through the glass stage 201 and projects onto the ultra-thin slotted glass.

[0025] The mounting base 21 includes a second support plate 211, which is disposed at both ends of the projection platform 1. A second fixing plate 212 is connected to the top of the second support plate 211, and the glass stage 201 is connected to the second fixing plate 212. The second support plate 211 is bolted to both ends of the projection platform 1, and the second fixing plate 212 is welded to the second support plate 211.

[0026] The projection platform 1 includes a base plate 101, on which partition lines 102 are evenly distributed. The base plate 101 is a flat plate, serving as a projection plate. The partition lines 102 provide reference coordinates for the inspectors, facilitating accurate recording and analysis of the glass's position during the inspection process, and measurement and inspection of the transition zone of the glass tank.

[0027] The limiting plate 202 has a limiting groove 4. The limiting groove 4 is a square groove, which can be used for measuring the transition area of ​​another glass groove of another size. The glass to be tested of another size is placed in the limiting groove 4 and fixed, which can facilitate the measurement of the glass to be tested, save time, and eliminate the need to position the glass to be tested.

[0028] The base plate 101 is an ivory white board with a one-piece molding structure. The base plate 101 adopts an ivory white board with a one-piece molding structure, which has good reflective properties and surface flatness. It can make the light projected by the diffused point light source 301 evenly distributed, ensuring that the projection of defects on the glass surface is clear and accurate, which is convenient for inspection personnel to observe and judge.

[0029] The role and effect of the embodiments

[0030] In use, the glass to be tested is placed on the stage 201, and fixed between two limiting plates 202 to prevent displacement. The diffused point light source 301 provides effective and stable diffused light. The light passes through the stage 201 and projects onto the base plate 101. The partition lines 102 on the base plate 101 provide reference coordinates for the inspector, facilitating accurate recording and analysis of the glass's position during the inspection process, and measurement and inspection of the transition zone of the glass groove. The partition lines 102 on the base plate 101 provide a good reference for observing and measuring the projected shape. This solves the problem of difficulty in observing and inspecting the transition zone and grooved area of ​​ultra-thin grooved glass, and provides auxiliary markings during the inspection process.
