The conveyor belt sequentially transports the glass cover plate to the cleaning assembly and the detection assembly.

[0043] After the spraying is completed, the telescopic rod is extended to push the glass cover plate that has been sprayed with fluorescent liquid from the pusher 11 to the conveyor belt. The conveyor belt is located below the cleaning assembly and the detection assembly, and the operation of the conveyor belt can sequentially transport the glass cover plate to the cleaning assembly and the detection assembly. When the glass cover plate reaches the cleaning assembly, the cleaning member 45 wipes the fluorescent liquid on the surface of the glass cover plate to ensure that only the fluorescent liquid remains at the defect or scratch. Then, the glass cover plate is continuously transported by the conveyor belt to the detection assembly, the ultraviolet light source 63 irradiates the surface of the glass cover plate, and the fluorescent liquid remaining in the defect or scratch is excited to emit light. Since the ultraviolet light cannot excite the glass cover plate itself to emit light, no strong reflected light is generated. The image acquisition device 62 can clearly capture the position of the defect, so that subtle scratches and shallow pits and other not obvious defects can also be checked out.

[0044] According to some embodiments of the utility model, the cleaning assembly comprises a fixed frame 40 and an elastic member 42, the fixed frame 40 is connected to the base 30 and hollowly forms a containing cavity 41, and the top and bottom thereof are provided with guide holes 46, the guide holes 46 are slidingly connected with slide rods 43, the protrusions 44 connected with the slide rods 43 are located in the containing cavity 41, one end of the slide rod 43 close to the conveying belt is connected with a cleaning member 45, the two ends of the elastic member 42 are connected with the top of the fixed frame 40 and the protrusion 44 respectively, the conveying belt drives the glass cover plate that has been sprayed with fluorescent liquid to move to below the cleaning assembly, the glass cover plate pushes the slide rod 43 and the protrusion 44 to slide upwards, the elastic member 42 is compressed and makes the cleaning member 45 closely adhere to the glass cover plate, so as to wipe the fluorescent liquid of the glass cover plate.

[0045] The conveying belt drives the glass cover plate that has been sprayed with fluorescent liquid to move to below the cleaning assembly. The glass cover plate contacts the cleaning member 45 at the lower end of the slide rod 43 and exerts an upward pushing force, pushing the slide rod 43 and the protrusion 44 to slide upwards along the guide holes 46. When the slide rod 43 rises, the protrusion 44 compresses the elastic member 42, making it generate a reverse elastic force and push the cleaning member 45 to closely adhere to the surface of the glass cover plate. During the continuous movement of the conveying belt, the cleaning member 45 wipes the glass cover plate with constant pressure, removing excess fluorescent liquid and retaining only the residue at the defect. When the glass cover plate completely passes through the cleaning assembly, the elastic member 42 rebounds, driving the slide rod 43 and the cleaning member 45 to reset, disengaging from the glass cover plate and waiting for the cleaning of the next glass cover plate.

[0046] According to some embodiments of the utility model, the glass cover plate surface defect rapid detection device further comprises a storage tank 50, the storage tank 50 and the cleaning assembly are separately arranged on both sides of the liquid storage tank 20, the storage tank 50 is provided with a slot 51, a limiting plate 52 and a storage groove 53 for storing glass cover plates, the storage groove 53 extends from the top end of the storage tank 50 to the bottom end of the storage tank 50, the slot 51 communicates with the storage groove 53, the first driving member 10 drives the pushing seat 11 to move to the storage tank 50 or the liquid storage assembly, and the limiting plate 52 can move to the storage groove 53 along the slot 51 to control whether the glass cover plate falls to the pushing seat 11.

[0047] The storage tank 50 is located on one side of the liquid storage tank 20, and is internally provided with a storage groove 53 for vertically stacking and storing a plurality of glass covers to be detected. The insertion groove 51 is in communication with the storage groove 53, the limiting plate 52 can move horizontally along the insertion groove 51, and is inserted or withdrawn from the storage groove 53 to block or release the glass cover. The pushing seat 11 is driven by the first driving member 10 and can reciprocate between the storage tank 50 and the liquid storage assembly. When the pushing seat 11 moves below the storage tank 50, the limiting plate 52 moves outward along the insertion groove 51 (withdraws from the storage groove 53), and the limiting of the bottommost glass cover is released. The bottommost glass cover automatically falls due to gravity and falls onto the pushing seat 11. The limiting plate 52 is then reinserted into the storage groove 53 to block the glass cover above from falling, ensuring that only one glass cover is released each time. Subsequently, the first driving member 10 moves the pushing seat 11 to transport the glass cover from below the storage tank 50 to the liquid storage assembly for fluorescent liquid spraying. After spraying is completed, the conveying belt sends the glass cover to the cleaning assembly for wiping, and finally enters the defect detection link. The pushing seat 11 returns to the storage tank 50 position, and the limiting plate 52 releases the next glass cover again. The above steps are repeated for the detection of the next glass cover.

The processing member is electrically connected with the image acquisition device 62 and is used for defect detection of images.

[0050] After the glass cover is sprayed and cleaned, the fluorescent liquid remaining on the surface is only attached to defects (such as cracks and scratches). The ultraviolet light source 63 is installed on the connecting frame 60 through the fixing rod 61, and the irradiation angle can be adjusted to ensure uniform light coverage on the surface of the glass cover. Under the excitation of ultraviolet light, the fluorescent liquid at the defect emits visible light, so that the defect is visible. The image acquisition device 62 is fixed on the connecting frame 60 and is aligned with the glass cover for shooting. The shot image is transmitted to the processing member (such as an industrial computer or an embedded processor), and the defects marked by the fluorescent liquid are automatically identified through image algorithms (such as edge detection and threshold segmentation), thereby realizing high-precision defect detection.
