[0028] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but the scope of protection of the present invention is not limited to the content described.

[0029] Please see Figure 1 and Figure 2 This application provides an industrial parts quality inspection device based on a smart camera, including a conveying mechanism 1, a flipping mechanism 2, a sorting mechanism 3, and a controller 4. The conveying mechanism 1 adopts a belt conveyor or a roller conveyor.

[0030] The conveying mechanism 1 is provided with a detection box 5 and a sorting mechanism 3 in sequence along its conveying direction. The detection box 5 is U-shaped and is upside down on the conveying mechanism 1. Its two sides are fixed to the frame of the conveying mechanism 1, thereby forming a square channel on the conveying mechanism 1.

[0031] The front end of the inspection box 5 is equipped with a first camera 6, and the left and right inner sides of the inspection box 5 are respectively equipped with a second camera 7 and a third camera 8. In actual installation, if the conveying mechanism 1 conveys from left to right, the left side of the inspection box 5 is defined as its front end, and the right side is defined as the rear end of the inspection box 5. The second camera 7 and the third camera 8 are located a distance behind the first camera 6, that is, the second camera 7 and the third camera 8 are roughly located in the middle of the inspection box 5. The first camera 6, the second camera 7 and the third camera 8 are all intelligent cameras. The intelligent cameras use an industrial computer as the core control unit, combined with a programmable logic controller (PLC) to realize the automated control of the entire inspection process. The image recognition algorithm is used to analyze the part images collected by the vision sensor to identify the type and location of defects on the surface of the part.

[0032] The detection box 5 is also equipped with a flipping mechanism 2 for flipping industrial parts, which can flip the parts vertically by at least 180 degrees; the sorting mechanism 3 is used to push out unqualified products on the conveying mechanism 1; the signal input terminal of the controller 4 is connected to the first camera 6, the second camera 7, and the third camera 8 respectively, and the controller 4 is connected to the conveying mechanism 1, the flipping mechanism 2, and the sorting mechanism 3 respectively.

[0033] The process of inspecting industrial parts using the aforementioned industrial parts quality inspection device includes the following steps:

[0034] S1. The industrial parts are placed on the conveying mechanism 1. The conveying mechanism 1 transports the industrial parts from left to right. When the industrial parts are transported to the area below the first camera 6, the first camera 6 recognizes that they have moved to the designated position. The first camera 6 transmits the relevant signals to the controller 4, and the controller 4 controls the conveying mechanism 1 to stop moving.

[0035] S2, the first camera 6, the second camera 7, and the third camera 8 scan and inspect the parts respectively, and preliminarily determine whether the parts are qualified by comparing them with the set standard scheme, and transmit the relevant image data to the controller 4. The controller 4 uses its internal analysis module to make a secondary judgment in combination with the parts library data, and then analyzes and processes it.

[0036] S3. Controller 4 controls the flipping mechanism 2 to flip the industrial parts so that the bottom of the industrial parts faces upward. Then, step S2 is repeated to re-evaluate the qualification of the industrial parts.

[0037] S4. Controller 4 controls the conveying mechanism 1 to operate again and continue to convey the industrial parts to the right. When the industrial parts move to the sorting mechanism 3, if it is determined that the industrial parts are unqualified at step S2 or step S3, controller 4 controls the sorting mechanism 3 to operate, thereby pushing the industrial parts off the conveying mechanism 1 and generating a detailed inspection report, including the part number, inspection results, reasons for non-compliance, and other information.

[0038] The industrial parts quality inspection device of this application can replace traditional manual quality inspection, eliminating the need for quality inspectors to personally enter the production workshop for quality inspection. This can effectively reduce the workload of quality inspectors and avoid the negative impact of environmental factors and heavy workload on quality inspectors.

[0039] Meanwhile, this application uses the flipping mechanism 2 to flip the industrial parts, so that both the upper and lower sides of the industrial parts can be detected, effectively ensuring the reliability of quality inspection.

[0040] In this embodiment, as Figure 3 As shown, the flipping mechanism 2 includes a vertical movement drive assembly 201, a flipping electric telescopic rod 202, a flipping motor 203, and a flipping suction cup 204. There are two vertical movement drive assemblies 201, which are respectively arranged opposite to each other on both sides of the detection box 5. The vertical movement drive assembly 201 is equipped with a flipping motor 203. The output shaft of the flipping motor 203 is equipped with a flipping electric telescopic rod 202. The telescopic rod of the flipping electric telescopic rod 202 extends into the detection box 5. The telescopic rod of the flipping electric telescopic rod 202 is equipped with a flipping suction cup 204.

[0041] When industrial parts need to be flipped, the two flipping electric telescopic rods 202 extend, and the flipping suction cups 204 at their ends can firmly adhere to the industrial parts. Then, the flipping motor 203 drives the flipping electric telescopic rods 202 to rotate, thereby flipping the industrial parts.

[0042] When the industrial part is rectangular or large in size, and its flipping would interfere with the conveying mechanism 1, the flipping suction cup 204 will hold the industrial part in place. Then, the up-and-down moving drive assembly 201 will drive the flipping electric telescopic rod 202 to move upward, thereby lifting the industrial part a certain distance, so that the flipping process of the industrial part can proceed smoothly.

[0043] Preferably, a pressure sensor can be installed between the flipping suction cup 204 and the flipping electric telescopic rod 202. The pressure sensor detects the pressure of the flipping electric telescopic rod 202 on the flipping suction cup 204, thereby determining whether the flipping electric telescopic rod 202 has extended to the correct position, effectively avoiding the technical problem of industrial parts being crushed.

[0044] In this embodiment, as Figure 4As shown, the up-and-down moving drive assembly 201 includes a drive motor 2011, a crank 2012, a sliding sleeve 2013, and a rectangular connecting frame 2014; the rectangular connecting frame 2014 is roughly rectangular and consists of two vertical rods and two horizontal rods.

[0045] The drive motor 2011 is fixedly mounted on the frame of the conveying mechanism 1. The output shaft of the drive motor 2011 is fixedly connected to one end of the crank 2012. The other end of the crank 2012 is hinged to a sliding sleeve 2013. The sliding sleeve 2013 is slidably connected to the bottom crossbar of the rectangular connecting frame 2014. The flipping motor 203 is fixedly mounted on the top crossbar of the rectangular connecting frame 2014.

[0046] When the drive motor 2011 is energized and rotates, it drives the crank 2012 to rotate, which in turn drives the tilting motor 203 to move upward through the rectangular connecting frame 2014. At the same time, the sliding sleeve 2013 adaptably moves left and right on the bottom crossbar of the rectangular connecting frame 2014. In some specific embodiments, the up-and-down movement drive assembly 201 may also be an electric telescopic rod.

[0047] In this embodiment, as Figure 3 As shown, the sorting mechanism 3 includes a push plate 301, a sorting electric telescopic rod 302, and a sorting conveyor belt 303; the sorting conveyor belt 303 is provided on the side of the conveying mechanism 1, and one end of the sorting conveyor belt 303 is connected to the side of the conveying mechanism 1; the sorting electric telescopic rod 302 is provided on the conveying mechanism 1, and the installation position of the sorting electric telescopic rod 302 corresponds to the position of the sorting conveyor belt 303, and the push plate 301 is provided on the telescopic rod of the sorting electric telescopic rod 302.

[0048] Thus, when the sorting electric telescopic rod 302 extends, it drives the push plate 301 to move towards the end of the sorting conveyor belt 303, thereby pushing the unqualified products off the conveying mechanism 1 and onto the sorting conveyor belt 303. The structure is simple and the operation is convenient.

[0049] In this embodiment, the inlet end of the conveying mechanism 1 is provided with a guide baffle 9. The front end of the guide baffle 9 is flared to laterally constrain the parts and transport them along a predetermined path. This ensures that when the two flipping electric telescopic rods 202 extend to the same length, the flipping suction cups 204 at their ends simultaneously contact the industrial parts, effectively ensuring the smooth progress of the flipping process.

Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
