Description

Technical Field

[0001] This application relates to the field of visual inspection technology, and in particular to a dust removal device and a visual inspection system for glass. Background Technology

[0002] In a visual inspection system, a light source illuminates the camera to help it capture images, thereby obtaining a clear image of the object being inspected. In practical applications, visual inspection of glass typically requires the light source to illuminate the glass from below at a specific angle. This highlights the features of the glass surface, making it easier for the camera to accurately capture relevant information.

[0003] However, in actual working environments, such as glass production or processing workshops, the air is filled with a large amount of dust; glass shards are generated during glass cutting and grinding processes; and water stains may also appear in environments with high humidity. These factors can cause dust, impurities, glass shards, and other pollutants to easily accumulate on the light-emitting surface of the light source, and may even form a mixture of water stains and dust.

[0004] These contaminants accumulated on the light-emitting surface of the light source can significantly affect its illumination. Dust and impurities can block the propagation of light, causing it to scatter and weaken; glass shards may alter the direction of light propagation; and a mixture of water stains and dust can form an uneven coating, further interfering with the normal emission of light. When the illumination effect of the light source is affected, the quality of the glass image captured by the camera deteriorates, leading to a decrease in the accuracy of visual inspection.

[0023] Please see Figure 1 and Figure 4 , Figure 1 This is a schematic diagram of the dust removal device. Figure 4 This is a schematic diagram of the dust removal device and the light source 2000. This application provides a dust removal device, including a base 1000 and an adjustment seat 1200 disposed on the base 1000. The adjustment seat 1200 is used to mount the light source 2000, and further includes: The conveyor belt 1300 is set on one side of the base 1000, and the guide rail 1400 is set above the conveyor belt 1300. The conveyor belt 1300 reciprocates along the setting direction of the guide rail 1400. A connecting plate 1500 is mounted on a conveyor belt 1300 and is movably connected to a guide rail 1400. The conveyor belt 1300 drives the connecting plate 1500 to move along the guide rail 1400. The cleaning component 1600 is mounted on the connecting plate 1500. The cleaning component 1600 moves above the adjusting seat 1200 as the connecting plate 1500 moves, so as to remove dust from the light source 2000 on the adjusting seat 1200.

[0024] In this embodiment, the dust removal device includes a base 1000, an adjusting seat 1200, a conveyor belt 1300, a connecting plate 1500, and a cleaning component 1600. Figure 1 As shown, the conveyor belt 1300 is positioned behind the base 1000, and a guide rail 1400 is positioned above the conveyor belt 1300, with the guide rail 1400's orientation parallel to the conveying direction. Two sets of guide wheels 1520 are also provided on the connecting plate 1500, arranged in pairs, vertically positioned to clamp the guide rail 1400, allowing the connecting plate 1500 to move along it. The connecting plate 1500 is fixedly mounted on the conveyor belt 1300, and when the conveyor belt 1300 moves, it drives the connecting plate 1500 to move along the guide rail 1400's orientation. An adjusting seat 1200 is also provided on the base 1000, and a light source 2000 is mounted on the adjusting seat 1200. The light source 2000 is elongated and its orientation is parallel to the guide rail 1400's orientation. It should be noted that the cleaning component 1600 is located on top of the connecting plate 1500, directly above the adjusting seat 1200, and is in contact with the light-emitting surface of the light source 2000. When the conveyor belt 1300 drives the connecting plate 1500 to reciprocate along the direction of the guide rail 1400, the cleaning component 1600 will reciprocate along the light-emitting surface of the light source 2000, thereby cleaning away debris from the light-emitting surface to ensure that the light source 2000 can complete the lighting work.

[0025] In some embodiments, the cleaning component 1600 includes a brush 1620 and a movable block 1610, the movable block 1610 being movably disposed on the top of the connecting plate 1500, and the brush 1620 being disposed on the movable block 1610.

[0026] In some embodiments, the top of the connecting plate 1500 has two mounting plates 1510 arranged opposite each other. One end of the movable block 1610 moves between the two mounting plates 1510 via a first rotating shaft 1512. A first positioning groove 1511 is provided on the mounting plate 1510. The movable block 1610 is fixed to the mounting plate 1510 by screws passing through the first positioning groove 1511.

[0027] In some embodiments, the brush 1620 is provided with a second positioning groove 1621, and the brush 1620 is mounted on the movable block 1610 by screws passing through the second positioning groove 1621. The relative position of the brush 1620 with the movable block 1610 can be adjusted along the setting direction of the second positioning groove 1621.

[0028] like Figure 2 As shown, Figure 2 This is a schematic diagram of the cleaning component 1600. In this embodiment, the cleaning component 1600 includes a movable block 1610 and a brush 1620. Two mounting plates 1510 are provided on the top of the connecting plate 1500 near the base 1000. One end of the movable block 1610 is mounted between these two mounting plates 1510 via a first rotating shaft 1512, allowing the other end of the movable block 1610 to rotate around the first rotating shaft 1512. In actual use, due to different areas requiring illumination, the angle of the light source 2000 needs to be adjusted to change the illumination direction of the light source 2000. To enable the cleaning component 1600 to better conform to the light-emitting surface of the light source 2000, a first positioning groove 1511 is also provided on the mounting plate. During operation, the movable block 1610 is first rotated around the first rotating shaft 1512 until the brush 1620 contacts the light-emitting surface of the light source 2000. At this time, the movable block 1610 reaches the appropriate position. Then, the screw is passed through the first positioning groove 1511 to fix the movable block 1610 on the mounting plate 1510.

[0029] A second positioning groove 1621 is provided on the brush 1620. Since the second positioning groove 1621 has a certain length, the specific installation position of the brush 1620 on the movable block 1610 can be flexibly adjusted according to the setting direction of the second positioning groove 1621. This design allows the installation position of the brush 1620 to be adjusted according to the size and dimensions of the light source 2000, ensuring that the brush 1620 is always in contact with the luminous surface of the light source 2000, thereby improving the cleaning effect.

[0030] In some embodiments, the cleaning assembly 1600 further includes two jet pipes 1630 located on either side of the movable block 1610.

[0031] In some embodiments, the connecting plate 1500 is further provided with an air guide pipe 1631, and the jet pipe 1630 is connected to the air pump through the air guide pipe 1631.

[0032] like Figure 2 As shown, in this embodiment, the cleaning component 1600 further includes a jet pipe 1630, an air guide pipe 1631, and an air pump. Specifically, two jet pipes 1630 are located on both sides of the movable block 1610, and the air guide pipe 1631 is located on the side of the connecting plate 1500 facing away from the base 1000. The air pump is connected to the two jet pipes 1630 through the air guide pipe 1631, thereby delivering airflow to the jet pipes 1630. In this embodiment, a plastic bamboo-joint tube can be selected as the jet pipe 1630. The plastic bamboo-joint tube has good adjustability, and its orientation can be adjusted arbitrarily. In actual use, the operator can adjust the position of the jet pipe 1630 according to the actual position and angle of the light source 2000 to ensure that the air outlet of the jet pipe 1630 is aligned with the light-emitting surface of the light source 2000, thereby using airflow to clean the surface of the light source 2000.

[0033] In summary, the design combining the jet nozzle 1630 with the brush 1620 further enhances the cleaning effect of the entire cleaning assembly 1600 on the light source 2000.

[0034] In some embodiments, grooved pulleys 1310 are provided at both ends of the conveyor belt 1300. One end of the conveyor belt 1300 is connected to a motor 1311, and the motor 1311 is used to drive the grooved pulley 1310 to rotate.

[0035] like Figure 1As shown, in this embodiment, a grooved pulley 1310 is provided at each end of the conveyor belt 1300, and a motor 1311 is connected to one of the grooved pulleys 1310. The motor 1311 drives the grooved pulley 1310 to rotate in a first direction or a second direction, and the first direction and the second direction are opposite. Specifically, when the motor 1311 drives the grooved pulley 1310 to rotate in the first direction, the conveyor belt 1300 and the connecting plate 1500 on the conveyor belt 1300 move to the left. When the connecting plate 1500 reaches the left end of the guide rail 1400, the motor 1311 drives the grooved pulley 1310 to rotate in the second direction, causing the conveyor belt 1300 and the connecting plate 1500 on the conveyor belt 1300 to move to the right. When the connecting plate 1500 reaches the right end of the guide rail 1400, the motor 1311 then drives the grooved pulley 1310 to rotate in the first direction, and so on. Preferably, the conveyor belt 1300 can be made of steel wire rope to ensure strength. This arrangement causes the connecting plate 1500 to reciprocate on the guide rail 1400, thereby causing the cleaning component 1600 to reciprocate on the light-emitting surface of the light source 2000 to complete the cleaning work of the light source 2000.

[0036] In some embodiments, the adjusting seat 1200 includes a support frame 1210 and a movable frame 1220. One end of the movable frame 1220 is connected to one end of the support frame 1210 via a second rotating shaft 1230. The other end of the support frame 1210 is provided with a screw 1211, which is used to adjust the distance between the other end of the movable frame 1220 and the other end of the support frame 1210.

[0037] like Figure 3 As shown, Figure 3 This is a schematic diagram of the adjusting seat 1200. In this embodiment, the movable frame 1220 is disposed above the support frame 1210. One end of the movable frame 1220 is movably connected to one end of the support frame 1210 via a second rotating shaft 1230. This allows the other end of the movable frame 1220 to rotate around the second rotating shaft 1230, thereby moving the other end of the movable frame 1220 closer to or further away from the other end of the support frame 1210. A screw 1211 is also disposed below the other end of the support frame 1210. When the screw 1211 is screwed into the support frame 1210, it can lift the movable frame 1220 on the support frame 1210, causing the movable frame 1220 to move away from the support frame 1210; conversely, when the screw 1211 is screwed out, the movable frame 1220 will move closer to the support frame 1210.

[0038] This application further proposes a visual inspection system for glass, including an inspection camera and a light source 2000 providing illumination for the inspection camera, as well as the aforementioned dust removal device. The specific structure of the dust removal device is as described in the above embodiments. Since this visual inspection system for glass adopts all the technical solutions of all the above embodiments, it at least has all the technical effects brought about by the technical solutions of the above embodiments, which will not be elaborated here. Figure 4 As shown, the light source 2000 is used to provide illumination for the detection camera, and the light source 2000 is mounted on the movable frame 1220 of the adjustment base 1200. By adjusting the distance between the movable frame 1220 and the support frame 1210, the tilt angle of the light source 2000 can be changed so that the light source 2000 can adjust the illumination area according to actual needs.

[0039] In some embodiments, the brush 1620 may come into contact with the light-emitting surface of the light source 2000 as the movable block 1610 moves.

[0040] In this embodiment, the movable block 1610 is rotated around the first rotating shaft 1512 until the brush 1620 on the movable block 1610 contacts the light-emitting surface of the light source 2000, and then the movable block 1610 is fixed so that the cleaning component 1600 can be adjusted according to the angle and position of the light source 2000 to ensure that the cleaning component 1600 is in the optimal dust removal position.

[0041] In summary, this application proposes a dust removal device and a visual inspection system for glass. The visual inspection system includes a dust removal device, an inspection camera, and a light source 2000. The dust removal device can adjust the position of the cleaning component 1600 according to the size and position of the light source 2000, effectively cleaning the light-emitting surface of the light source 2000, ensuring stable illumination of the light source 2000, thereby improving the accuracy of visual inspection of glass.
