Description

Technical Field

[0001] This utility model belongs to the field of sheet metal parts inspection, and specifically relates to an inspection device for curved sheet metal parts. Background Technology

[0002] Sheet metal processing is a comprehensive cold working process for thin metal sheets (usually less than 6mm), including shearing, punching / cutting / combined cutting, bending, welding, riveting, splicing, and forming (such as car bodies). Its most significant characteristic is that the thickness of the same part is consistent. Products processed through sheet metal processing are called sheet metal parts. Sheet metal parts are characterized by their light weight, high strength, electrical conductivity (suitable for electromagnetic shielding), low cost, and good mass production performance. They are widely used in electronics, communications, automotive, and medical devices. For example, sheet metal parts are essential components in computer cases, mobile phones, and MP3 players. The term "sheet metal part" generally varies across different industries and is often used in assembly contexts.

[0003] In the existing technology, the processing of sheet metal parts usually adopts manual observation and inspection. During the inspection process, workers will observe the sheet metal parts with the naked eye. However, if the sheet metal parts are curved, it is not convenient to observe them manually. Observing both sides of the sheet metal parts will greatly increase the inspection time and make it difficult to improve the inspection efficiency. Therefore, a curved sheet metal parts inspection device was designed. Utility Model Content

Each transmission shaft 2 has a vertical plate at both ends. The vertical plate has a through hole, and a bearing is fixedly installed in the through hole. The two ends of the transmission shaft 2 pass through the bearing on the vertical plate and are fixedly connected to the inner ring of the bearing. Each transmission shaft 2 is fitted with a transmission roller 3. A transmission belt 4 is fitted on the two transmission rollers 3. The side of the transmission belt 4 that contacts the transmission roller 3 has mutually matching protrusions and depressions to prevent the transmission belt 4 from slipping and thus affecting the inspection efficiency.

[0030] To inspect curved sheet metal parts, an inspection component is provided above each transmission assembly. The inspection component includes two support arms 5, which are located on both sides of the transmission belt 4. A crossbeam 6 is provided between the support arms 5. A first electric push rod 7 is provided on the lower surface of the crossbeam 6. The first electric push rod 7 is connected to a motor. The movable end of the first electric push rod 7 faces the transmission belt 4 and is rigidly connected to a moving plate 8 by bolts. Vertically extending guide rails 9 are provided on the side surfaces of the support arms 5 that are close to each other. Guide blocks 10 are provided in each guide rail 9. The two guide blocks 10 are respectively connected to the two ends of the moving plate 8. The moving plate 8 can be moved along the length of the guide rails 9 by the first electric push rod 7.

Limiting rings 19 are provided on both sides of the support plate 17 and the connecting plate 18 respectively. An opening is provided on one side of the limiting ring 19. The lower end of the opening is flush with the upper surface of the transmission belt 4.

[0032] When one end of the curved sheet metal part moves into the flipping assembly, a fixing component is provided on the flipping assembly to fix the curved sheet metal part. The fixing component includes a baffle 20, which is located between the limiting rings 19. Both ends of the baffle 20 are fixedly connected to the limiting rings 19 on both sides. The baffle 20 is located on the other side of the opening on the limiting ring 19. A gasket 21 is provided on the side of the baffle 20 near the center of the limiting ring 19. The gasket 21 can prevent the curved sheet metal part from colliding with the baffle 20 and causing damage. The lower surface of the connecting plate 18 is provided with a second electric push rod 22. The movable end of the second electric push rod 22 faces the support plate 17. A clamping plate 23 is provided between the support plate 17 and the connecting plate 18. The movable end of the second electric push rod 22 is rigidly connected to the clamping plate 23 by bolts. A sensor is provided on the gasket 21. When the curved sheet metal part contacts the gasket 21, the sensor controls the second electric push rod 22 to work. The clamping plate 23 and the support plate 17 can fix curved sheet metal parts of different sizes and then flip them.

[0033] To ensure the flipped curved sheet metal part moves more stably over the transmission belt 4 on the other side, an adjustment assembly is provided on the fixed plate 12. The adjustment assembly includes a movable plate 24, with slide plates 25 connected to both ends of the movable plate 24. The slide plates 25 are located on both sides of the fixed plate 12.

A through hole is provided on the movable plate 24, and one end of the connecting shaft 15 located outside the fixed plate 12 passes through the through hole in the movable plate 24. The connecting shaft 15 is perpendicular to the movable plate 24. The device is equipped with bearings. One of the movable plates 24 is fixedly mounted with a drive motor 27, and the output end of the drive motor 27 is fixedly connected to one of the connecting shafts 15. The other movable plate 24 is equipped with a limit rod 28. The fixed plate 12 connected to this movable plate 24 is equipped with a fixed shaft 29. A turntable 30 is fixedly connected to the fixed shaft 29. The turntable 30 is equipped with a transmission rod 31. Both the limit rod 28 and the transmission rod 31 are equipped with collars. A fixed rod 32 is provided between the collars. When the turntable 30 rotates, the movable plate 24 moves along the length direction of the rectangular opening 13 when passing through the fixed rod 32.

[0034] Working principle: The operator places several curved sheet metal parts to be inspected sequentially on the conveyor belt 4 on one side of the processing table 1. At this time, the curved sheet metal parts will pass under the detection component. The position of the detection probe 11 is adjusted, and the surface of the curved sheet metal parts is photographed by the detection probe 11 and identified by the program. When the curved sheet metal parts move to the flipping component, the sensor controls the fixing component to clamp them, and the drive motor 27 controls the flipping component to flip. When the curved sheet metal parts are flipped to the top of the conveyor belt 4 on the other side, the horizontal height of the flipping component is controlled by the adjusting component, so that the curved sheet metal parts contact the corresponding surface of the conveyor belt 4. At this time, the clamping plate 23 in the fixing component moves away from the curved sheet metal parts, so that the curved sheet metal parts move under another detection component, realizing the detection of both sides of the curved sheet metal parts.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this invention.
