Description

Technical Field

[0001] This utility model relates to the field of metal bowl inspection technology, specifically a comprehensive online visual inspection system for metal bowls. Background Technology

[0002] Metal bowls may develop defects during production and use, such as cracks, rust spots, and foreign object contamination. These defects not only affect the appearance and lifespan of the product, but may also pose a threat to consumers' health. Therefore, it is essential to conduct rigorous testing on metal bowls.

[0003] Traditional metal bowl inspection primarily relies on manual visual inspection, a method with several significant limitations. First, due to the large size of metal bowls, manual inspection is relatively time-consuming, making it inefficient in fast-paced production environments and failing to meet the speed requirements of production lines. Second, the visual inspection of metal bowls needs to be comprehensive on the production line, where manual intervention is often limited and inconvenient. Furthermore, manual inspection is heavily influenced by subjective judgment, which can lead to inconsistencies in results, thus affecting the stability and reliability of product inspection. Utility Model Content

Secondly, the appearance inspection of metal bowls needs to be comprehensive on the production line, but manual intervention on the production line is often limited and inconvenient. Furthermore, manual inspection is significantly influenced by subjective judgment, which can lead to inconsistencies in inspection results.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an all-round online visual inspection system for metal bowls, including a strip plate and a control terminal, wherein a detection mechanism and a sorting mechanism are respectively arranged on the top of the strip plate;

[0006] The detection mechanism includes a U-shaped block fixedly connected to the top of the strip plate, a servo motor fixedly installed on the U-shaped block via a servo motor frame, and a flipping assembly set on the top of the inner cavity of the U-shaped block.

An area array camera and a sensing sensor are fixedly installed on the bottom of the circular plate, and an L-shaped plate is fixedly connected to the side wall of the circular plate. A line array camera is fixedly installed on the other end of the L-shaped plate.

[0007] The present invention is further configured such that: the flipping assembly includes an electric telescopic column 1 fixedly connected to the top of the inner cavity of a U-shaped block 1, a fixed plate fixedly connected to the other end of the electric telescopic column 1, and a servo motor 2 fixedly connected to the outer wall of the fixed plate through a servo motor frame 2.

[0008] Using the above technical solution, the control terminal controls the first electric telescopic column to extend and retract, which will move the fixed plate to a set height. Then, the control terminal controls the second electric telescopic column to extend, which will move the clamping block to the outer wall of the metal bowl, thereby clamping the metal bowl. Then, the control terminal controls the first electric telescopic column to rise to a certain height, and the control terminal controls the second servo motor to rotate 180 degrees. Next, the control terminal controls the first electric telescopic column to extend to the set height, and controls the second electric telescopic column to retract, causing the clamping block to retract, thereby realizing the flipping of the metal bowl, so that the area scan camera can take pictures and detect the bottom of the metal bowl.

The control terminal determines whether the processed part that has reached the distance sensor is qualified or unqualified based on the quality of the detected processed part and the moving speed of the processed part. Then, it controls the electric telescopic column to extend or shorten, so that qualified processed parts go out through one channel and unqualified processed parts go out through another channel. This achieves the goal of removing unqualified processed parts, greatly reducing the workload of manual visual sorting, and at the same time greatly improving sorting efficiency.

Then, control terminal 2 controls the electric telescopic column 385 to extend, which will move the clamping block 386 to the outer wall of the metal bowl, thereby clamping the metal bowl. Then, control terminal 2 controls the electric telescopic column 381 to rise to a certain height. Control terminal 2 controls the servo motor 383 to rotate 180 degrees.

[0037] When the distance sensor 44 senses the metal bowl approaching, it transmits a signal to the control terminal 2. The control terminal 2 determines whether the processed part that has reached the distance sensor 44 is qualified or unqualified based on the qualified or unqualified status of the processed part after detection and the moving speed of the processed part. Then, it controls the electric telescopic column 3 45 to extend or shorten, so that qualified processed parts go out through one channel and unqualified processed parts go out through another channel.

The control panel is responsible for the human-computer interaction channel, controlling the start and stop of the entire device, setting parameters, and visualizing the test results.

[0040] Working Principle: During operation, the workpiece to be tested is conveyed onto conveyor belt 6 after production. The control terminal controls the pneumatic conveyor motor 5, which drives the drive shaft. Under the combined action of the drive shaft, transmission rollers, driven shaft, and conveyor belt 6, the workpiece is sequentially transported to the detection mechanism 3. At this point, the sensing sensor 35 detects the metal bowl, and the control terminal 2 stops the conveyor motor 5. Then, the control terminal 2 controls the area scan camera 34 to take pictures of the inside of the metal bowl, while simultaneously controlling the servo motor 32 to rotate 360 ​​degrees. During this process, the line scan camera 37 scans and takes pictures of the side of the metal bowl. After taking pictures, the control terminal 2 controls the electric telescopic column 381 to extend and retract, which in turn moves the fixed plate 382... The device moves to a set height, and then the control terminal 2 controls the electric telescopic column 385 to extend. The electric telescopic column 385 drives the clamping block 386 to move to the outer wall of the metal bowl, thereby clamping the metal bowl. Then, the control terminal 2 controls the electric telescopic column 381 to rise to a certain height, and the control terminal 2 controls the servo motor 383 to rotate 180 degrees. Then, the control terminal 2 controls the electric telescopic column 381 to extend to the set height, and controls the electric telescopic column 385 to retract, so that the clamping block 386 retracts, thereby realizing the flipping of the metal bowl. The array camera 34 takes pictures of the bottom of the metal bowl for detection, thereby achieving all-round detection of the metal bowl, which greatly improves the detection efficiency and avoids the influence of subjective judgment in traditional manual detection.

[0041] Control terminal 2 continues to control the operation of conveyor motor 5, and conveyor belt 5 will transport the workpiece to be tested to sorting mechanism 4. When distance sensor 44 senses the metal bowl approaching, it transmits a signal to control terminal 2. Control terminal 2 determines whether the workpiece that has reached distance sensor 44 is qualified or unqualified based on whether the workpiece is qualified after detection and the moving speed of the workpiece. Then, it controls the electric telescopic column 45 to extend or shorten, so that qualified workpieces go out through one channel and unqualified workpieces go out through another channel, thereby removing unqualified workpieces, greatly reducing the workload of manual visual sorting, and greatly improving sorting efficiency.
