Abstract
Description
Technical Field
[0001] This utility model relates to the field of quality inspection technology, specifically to an artificial visual inspection table for AG glass. Background Technology
[0002] With the increasing demand for AG glass in electronics, architectural decoration, and other fields, quality control has become a crucial link in the production process. Currently, manual visual inspection of AG glass mainly relies on traditional inspection environments and methods, which presents numerous problems affecting inspection effectiveness and efficiency. Uneven front lighting can cause shadows and reflections on the glass surface, interfering with inspectors' observation and judgment of defects such as flaws and scratches, significantly reducing inspection accuracy. Moreover, the fixed light source cannot flexibly adjust the lighting angle and intensity according to different inspection needs, making it difficult to focus on specific areas of the glass and hindering the detection of subtle defects that are difficult to detect under normal lighting conditions. Utility Model Content
[0003] The purpose of this invention is to propose an artificial visual inspection station for AG glass, which can improve the accuracy and efficiency of inspection.
[0004] To achieve the above objectives, this disclosure provides an AG glass manual visual inspection station, including a base, a back plate, and a top plate. The base is fixedly connected to the lower end of the back plate, and the upper end of the back plate is fixedly connected to the top plate. The back plate is provided with uniformly distributed front light sources. The top plate is provided with a top adjustable light source, which includes a point light source device with adjustable angle and height. The point light source device is fixed to the top frame of the inspection station by an adjustable bracket, and the bracket and the top frame are connected by an adjustable connection structure. The back plate is provided with a distance sensor, and the top plate is provided with a light sensor. The distance sensor and the light sensor are connected to a controller, and the controller is also connected to the front light source and the top adjustable light source.
[0005] Beneficial effects of the basic solution: The base, back plate, and top plate form the AG glass inspection area. The fixed connection of the base, back plate, and top plate forms a stable frame structure, providing stable support for the inspection table and ensuring that the inspection results will not be affected by external shaking or vibration during the inspection process. At the same time, it is also conducive to protecting the stability and service life of equipment such as light sources.
[0006] The back panel features evenly distributed front light sources, providing uniform front illumination to the AG glass, reducing shadows and reflections, and allowing inspectors to more clearly observe defects such as flaws and scratches on the glass surface, thus improving inspection accuracy. The top adjustable light source includes a point light source device with adjustable angle and height. The position and angle of the point light source can be flexibly adjusted according to different inspection needs and the glass placement angle, achieving focused illumination of specific areas of the glass, further enhancing the lighting effect and helping to detect subtle defects that are difficult to detect under normal lighting.
[0007] The distance sensor detects the distance between the personnel and the inspection table, which can automatically turn the light source on and off. The light source does not need to run at high power for a long time, saving energy and extending the life of the light source. In order to protect the AG glass, both hands are needed to hold the AG glass firmly when entering the inspection area during inspection. Turning on and off the light source requires one hand to be freed up. This embodiment can save this process.
[0008] At the same time, the brightness of the light source is automatically adjusted according to the ambient light intensity to ensure that the AG glass surface is illuminated by light of uniform and appropriate intensity, thereby improving the accuracy of inspection. It also saves the time of frequently adjusting the intensity, brightness and angle of the light source, thus improving the efficiency of inspection.
[0009] At the same time, inspectors can gradually adapt to the light as they get closer to the inspection table, avoiding the glare of strong light when inspectors are too close to the inspection table.
[0010] As a feasible preferred solution, the front light source is a long strip of light, which is installed along the length of the front of the inspection table and is parallel to the front of the inspection table. The light strip is fixed in a pre-set mounting groove on the front of the inspection table by fasteners, and the depth and width of the mounting groove are adapted to the size of the light strip.
[0011] As a feasible preferred embodiment, the top plate is uniformly equipped with multiple light sensors, and the controller generates a control signal to turn on the top adjustable light source near the position of the light sensor.
[0012] As a feasible preferred embodiment, the base, back plate, and top plate are all made of metal.
[0013] As a preferred feasible option, the surfaces of the base, back plate, and top plate are made of a black high-contrast material.
[0014] As a preferred feasible option, the back plate or base has a pen holder placement area on its side.
[0015] As a feasible preferred embodiment, the inspection table is equipped with a control switch for controlling the on and off of the top adjustable light source and the front light source, as well as adjusting the brightness of the light source. Attached Figure Description

[0019] To make the technical solution and advantages of this application clearer, the technical solution of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some embodiments of this utility model, and are only used to explain this application, not to limit it. It should be noted that the technical features or combinations of technical features described in the following embodiments should not be considered isolated; they can be combined with each other to achieve better technical effects. The same reference numerals appearing in the accompanying drawings of the following embodiments represent the same features or components, and can be applied to different embodiments.
[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "set" and "connection" should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection (including various forms of mechanical connection, such as couplings or gear pairs), or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0021] Furthermore, unless otherwise defined, the technical or scientific terms used in this description shall have the ordinary meaning as understood by one of ordinary skill in the art to which this invention pertains.
[0022] The present invention will now be described in further detail with reference to the accompanying drawings:
[0023] Reference numerals: base 1, back plate 2, top plate 3.
[0024] Reference Figures 1 to 3 An AG glass manual visual inspection table includes a base 1, a back plate 2, and a top plate 3. The base 1 is fixedly connected to the lower end of the back plate 2, and the upper end of the back plate 2 is fixedly connected to the top plate 3. The angle between the top plate 3 and the back plate 2 is 90°. The base 1, back plate 2, and top plate 3 are preferably made of metal to ensure the stability and durability of the entire inspection table. The base 1, back plate 2, and top plate 3 are preferably made of a high-contrast black material to help highlight imperfections on the AG glass surface.
[0025] The back panel 2 or the base 1 has a pen holder area on its side for storing pens and other stationery for recording, so that inspectors can record inspection results at any time.
[0026] The back panel 2 is equipped with evenly distributed front light sources, which are long, strip-shaped LED strips installed along the length of the front of the inspection table and parallel to it. The LED strips are secured to pre-set mounting slots on the front of the inspection table using clips or screws. The depth and width of the mounting slots are matched to the size of the LED strips to ensure secure and accurate installation. The purpose of the front light sources is to supplement illumination from the front, reducing shadows on the AG glass surface caused by top lighting and further improving the visibility of defects. When used in conjunction with the top adjustable light source system, it enables more comprehensive and accurate detection of defects on the AG glass surface. It connects to a power cord to provide power.
[0027] The top plate 3 is equipped with an adjustable top light source, including a point light source device with adjustable angle and height, which can adjust the illumination angle and intensity of the light according to the inspection requirements. The light source device is fixed to the top frame of the inspection table by an adjustable bracket, and the bracket and the top frame are connected by an adjustable connection structure, such as a telescopic cantilever or a rotatable and lifting bracket connection method, which is convenient for adjustment and fixation.
[0028] The inspection table is equipped with control switches to control the on and off of the top adjustable light source and the front light source, as well as to adjust the brightness of the light source.
[0029] The inspection process is as follows: Turn on the top adjustable light source and the front light source, and adjust the angle and brightness of the top light source as needed; identify and record defects by observing the surface condition of the AG glass under a black background and high-brightness light source; after the inspection is completed, turn off the light source to complete the inspection process.
[0030] Example 2
[0031] The technical feature that distinguishes this embodiment from the above embodiments is that the back panel 2 is provided with a distance sensor, the top panel 3 is provided with a light sensor, the distance sensor and the light sensor are connected to the controller, and the controller is connected to the front light source and the top adjustable light source.
[0032] The distance sensor detects people approaching or moving away and automatically turns on the front light source. When the AG glass enters the detection area (the space formed by the detection platform, back panel 2, and top panel 3), the light sensor detects the object, the controller sends a control signal to turn on the top adjustable light source, and the brightness is adaptively adjusted according to the ambient light intensity.
[0033] Since the inspection table is generally long enough to accommodate multiple people working at the same time, in one embodiment, multiple light sensors are evenly arranged on the top plate 3, and the controller generates a control signal to turn on the top adjustable light source near the position of the light sensor.
[0034] This technical solution can automatically turn the light source on and off, eliminating the need for the light source to operate at high power for extended periods, thus saving energy and extending its lifespan. In order to protect the AG glass, it is necessary to hold the AG glass firmly with both hands when entering the inspection area during inspection, and turning the light source on and off requires a separate hand to operate. This technical solution can save this process.
[0035] At the same time, the brightness of the light source is automatically adjusted according to the ambient light intensity to ensure that the AG glass surface is illuminated by light of uniform and appropriate intensity, thereby improving the accuracy of inspection. It also saves the time of frequently adjusting the intensity, brightness and angle of the light source, thus improving the efficiency of inspection.
[0036] At the same time, inspectors can gradually adapt to the light as they get closer to the inspection table, avoiding the glare of strong light when inspectors are too close to the inspection table.
