[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-8 This utility model provides a technical solution: an automated inspection device for the appearance of HUD white glass, comprising: an upper frame 1, a main body 2 and a lower frame 3;

[0027] The main structure 2 consists of a conveying mechanism 21, a glass centering mechanism 22, a glass side inspection station 23, a glass front inspection station 24, a glass back inspection station 25, and a magnetic roller conveyor line 26. Two parallel magnetic roller conveyor lines 26 traverse the glass side inspection station 23, the glass front inspection station 24, and the glass back inspection station 25, forming a dual-channel inspection system. The conveying mechanism 21 is located between the ends of the two magnetic roller conveyor lines 26. The function of the conveying mechanism 21 is to separate the two pieces of glass exiting the washing machine, allowing them to flow into the washing machine. Each magnetic roller conveyor line 26 has its own inspection channel. The loading end of each line is equipped with a glass centering mechanism 22. The glass centering mechanism 22 centers and straightens the incoming glass, ensuring that the product is transported in the center of the magnetic roller conveyor line 26. The glass side inspection station 23 uses a camera to detect defects on the two long sides of the glass. The glass front inspection station 24 and the glass back inspection station 25 use a line scan camera to detect defects on both sides of the glass. The magnetic roller conveyor line 26 transports glass products with high precision and stability. The product's vertical movement accuracy is ≤0.1mm.

[0028] The conveying mechanism 21 includes a Y-axis servo motor 211, which drives the Y-axis module 214 to move left and right. A nylon tray 212 is mounted on the Y-axis module 214 via a lifting cylinder 213. The nylon tray 212 adopts an equidistant upright plate design. When the upright plate is raised, it can pass through the magnetic roller conveyor line 26, lifting the glass away from the magnetic roller conveyor line 26. The lifting cylinder 213 lifts the nylon tray 212, and the glass is placed on the nylon tray 212. The Y-axis module 214 completes the movement in the Y-axis direction. After the lifting cylinder 213 lifts the glass tray 212, the Y-axis servo motor 211 drives the Y-axis module 214 to complete the movement in the Y-axis direction. The lifting cylinder 213 retracts the nylon tray 212 to complete one Y-axis conveying of the glass.

[0029] The glass centering mechanism 22 includes a first servo motor 221, which drives the connected split-module 222 to achieve simultaneous opening and closing of the modules. The split-module 222 includes two relatively movable platforms with several insert teeth 223. The ends of the insert teeth 223 are integrally provided with polyurethane cylinders 224. The design of the insert teeth 223 allows them to pass through the magnetic roller conveyor line 26 to contact the glass. By driving the split-module 222 with the first servo motor 221, the two sets of polyurethane cylinders 224 move relative to each other to straighten the glass.

[0030] The glass side inspection station 23 includes two sets of Z-axis servo motors 231 and two sets of coaxial light sources 235. The Z-axis servo motors 231 drive and connect to the Z-axis module 232. Two sets of symmetrical 500W cameras 233 are set on the sliding part of the Z-axis module 232, each with a lens 234. The lenses are aligned with the two sides of the glass by 90-degree refraction through the coaxial light source. The two are used together to detect defects on the long side and side edges of the glass. Each set of coaxial light sources 235 has two lenses, and each coaxial light source 235 is matched to the side of one camera 233. Its function is to emit strong light to make the image of the glass edge clearer and refract it 90° to the camera 233 to form an image and take a picture. Since the glass sizes are different, the object distance between the lens 234 and the glass being inspected needs to be adjusted. Therefore, the Z-axis servo motors 231 and the Z-axis module 232 need to be used in combination to ensure that the glass being inspected and the lens 234 are always kept at a fixed distance.

[0031] The glass front inspection station 24 is equipped with a three-axis movable front line scan camera 243 and three sets of front line scan light sources 241 in each inspection channel. A light shield is set between two channels. The front line scan camera 243 is equipped with a front line scan lens 242. The front line scan light source 241 is manually calibrated to rotate. The glass front inspection station 24 detects defects on the front of the HUD white glass. The front line scan light source 241 illuminates the HUD white glass to highlight appearance defects such as scratches, dirt, surface chips, and edge chips on the front of the product. The front line scan lens 242 and the front line scan camera 243 are used together to achieve the detection of defects on the front of the glass.

[0032] The glass reverse inspection station 25 is equipped with three sets of reverse line scan light sources 251 and one set of reverse line scan cameras 253 in each channel. The reverse line scan camera 253 and two sets of reverse line scan light sources 251 are located below the magnetic roller conveyor line 26, and one set of reverse line scan light sources 251 is located above the magnetic roller conveyor line 26. The reverse line scan camera 253 is equipped with a reverse line scan lens 252. The reverse line scan light source 251 illuminates the HUD white glass to highlight appearance defects such as scratches, dirt, surface chips, large defects, and edge chips on the reverse side of the product. The reverse line scan lens 252 and the reverse line scan camera 253 are used together to achieve the detection of defects on the reverse side of the glass.

[0033] The magnetic roller conveyor line 26 includes a second servo motor 261 and a reducer 262, which together form a power drive device. The output end of the reducer 262 is connected to a synchronous pulley 263, which is driven by a synchronous belt 264. The synchronous belt 264 is driven by a drive shaft 266, which is driven by a magnetic wheel 265. The magnetic wheel 265 is coaxially and fixedly connected to a passive shaft 267. A nylon roller 268 is installed on the passive shaft 267. The second servo motor 261 and the reducer 262 drive the drive shaft 266 to rotate. The drive shaft 266 drives the passive shaft 267 to rotate through the magnetic attraction between itself and the magnetic wheel 265. The passive shaft 267 drives the nylon roller 268 to rotate, so that the HUD white glass product is transported smoothly on the magnetic roller conveyor line 26.
