[0002] This section merely provides background information related to the present disclosure and is not necessarily prior art.

[0003] In modern society, the concept of environmental protection is becoming more and more popular. Many countries and regions have issued plastic bans, gradually eliminated plastic products, and encouraged the use of biodegradable and environmentally friendly materials as substitutes. At present, my country is also vigorously promoting the use of environmentally friendly materials and has achieved remarkable results. The use of paper-plastic lunch boxes instead of plastic lunch boxes is a typical link.

[0004] During the molding process, some paper plastic products will produce defective products. This can be caused by a variety of factors, including damage caused by insufficient pulp concentration in certain areas and residual impurities in the pulp that result in a poor appearance. Therefore, it is necessary to inspect both the front and back of the product and eliminate defective products. Existing production lines only design one set of inspection equipment for a single product, making it incompatible with products of varying sizes and models. This results in high production costs. Furthermore, during product inspection, the inspection equipment obstructs the camera, resulting in poor image quality and inaccurate inspections. Summary of the Invention

[0034] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments described herein. Rather, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0035] It should be understood that the terms used herein are for the purpose of describing specific example embodiments only and are not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms "one", "an" and "said" as used herein may also be meant to include plural forms. The terms "comprise", "include", "contain" and "have" are inclusive and therefore specify the presence of stated features, steps, operations, elements and / or parts, but do not exclude the presence or addition of one or more other features, steps, operations, elements, parts, and / or combinations thereof. The method steps, processes, and operations described herein are not to be construed as necessarily requiring them to be performed in the specific order described or illustrated, unless the order of execution is clearly indicated. It should also be understood that additional or alternative steps may be used.

[0036] Although the terms first, second, third, etc. can be used in the text to describe multiple elements, components, regions, layers and / or sections, these elements, components, regions, layers and / or sections should not be limited by these terms. These terms can only be used to distinguish an element, component, region, layer or section from another region, layer or section. Unless the context clearly indicates otherwise, terms such as "first", "second" and other numerical terms do not imply order or sequence when used in the text. Therefore, the first element, component, region, layer or section discussed below can be referred to as the second element, component, region, layer or section without departing from the teaching of the example embodiments.

[0037] For ease of description, spatially relative terms may be used herein to describe the relationship of one element or feature relative to another element or feature as shown in the figures, such as "inside," "outside," "inside," "outside," "below," "beneath," "above," and the like. Such spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is flipped, an element described as "below" or "beneath" another element or feature would then be oriented as "above" or "above" the other element or feature. Thus, the example term "below" can include both above and below orientations. The device may be oriented otherwise (rotated 90 degrees or in other orientations) and the spatially relative descriptors used herein should be interpreted accordingly.

[0038] like Figures 1 to 3 As shown, one embodiment of the present invention provides a product inspection device 1, which includes: a feeding mechanism 10, an image acquisition device 20, a rotation detection mechanism 30, a stacking mechanism 40, and a control mechanism (not shown). The feeding mechanism 10 includes a first detection position 141. The rotation detection mechanism 30 includes a shifting device 32 and a second detection position 311. The shifting device 32 includes a rotating platform 321 and at least one pickup portion 322 disposed on the rotating platform 321. The pickup portion 322 is capable of picking up and placing products. The first detection position 141 and the second detection position 311 are both located around the rotating platform 321. The image acquisition device 20 also includes a first image acquisition device 21 and a second image acquisition device 22. The first image acquisition device 22 acquires an image of the product at the first detection position 141 in a first direction, and the second image acquisition device 22 acquires an image of the product at the second detection position 311 in a second direction.

[0039] The feeding mechanism 10 includes a first conveyor belt 11, a second conveyor belt 12 connected to one end of the first conveyor belt 11, a positioning device 14 located at the end of the second conveyor belt 12, and a width adjustment device 13 connected to the second conveyor belt 12. The products to be inspected enter the first conveyor belt 11 in sequence and are arranged regularly along a straight line after passing through the first conveyor belt 11 and the second conveyor belt 12.

[0040] The first conveyor belt 11 includes a first conveyor belt body 111, and first and second straightening rods 112, 113, disposed on either side of the first conveyor belt body 111. The first straightening rods 112 and the first conveyor belt body 111 form a first angle, while the second straightening rods 113 and the second conveyor belt body 111 form a second angle. Before each inspection of a new product, the angle between the first and second straightening rods 112, 113 is adjusted based on the product's size, ensuring that the product is straightened after passing through the first and second straightening rods 112, 113. It will be appreciated that the feeding mechanism 10 also includes a first motor to drive the movement of the first running belt.

[0041] The second conveyor belt 12 comprises a second running belt. The second running belt includes an infeed end and an outfeed end. The infeed end of the second running belt connects with the outfeed end of the first running belt, allowing products to move smoothly from the outfeed end of the first running belt to the infeed end of the second running belt. It will be appreciated that the feeding mechanism 10 also includes a second motor to drive the movement of the second running belt.

[0042] The width adjustment device 13 includes a first limiting rod 131 and a second limiting rod 132. The width adjustment device 13 adjusts the distance between the first limiting rod 131 and the second limiting rod 132, causing them to move closer or further apart. This distance between the first limiting rod 131 and the second limiting rod 132 is slightly larger than the width of the product. This ensures that after passing through the first limiting rod 131 and the second limiting rod 132, the products are arranged in a regular pattern, connected end to end along a straight line.

[0043] The positioning device 14 is disposed at the output end of the second conveyor belt 12. The structure of the positioning device 14 is not limited, as long as it can serve to position the product. In this embodiment, the positioning device 14 includes a positioning plate and a fixing rod that fixes the positioning plate to the output end of the second conveyor belt 12. The position where the product abuts the positioning device 14 is defined as the first detection position 141, and the product will undergo the first detection at the first detection position 141. The first detection position 141 is disposed on the periphery of the rotating platform 321, so that the pickup portion 322 of the shifting device 32 can pick up the product from the product pickup station 141.

[0044] The image acquisition device 20 includes a first image acquisition device 21 and a second image acquisition device 22. The first image acquisition device 21 is located above the first inspection position 141 and spaced apart from the product at the first inspection position 141. The first image acquisition device 21 includes at least one camera. The camera captures the product from directly above, or from both directly above and at least one diagonally above, to capture images of the front of the product. Because the first image acquisition device 21 is spaced apart from the product at the first inspection position 141, the first image acquisition device 21 can automatically adjust the shooting angle and focal length of each camera, enabling high-precision capture of products of different sizes and models. The first image acquisition device 21 is located around the shifting device 32, so the shifting device 32 does not obstruct the image capture of the product. A control mechanism is electrically connected to the image acquisition device 20 to control the cameras. The image acquisition device 20 transmits the captured images to the control mechanism, which analyzes the images to identify defects on the front of the product, such as whether the product is good or defective.

[0045] The rotation detection mechanism 30 includes a detection platform 31 and a shifting device 32. The shifting device 32 is located above the detection platform 31, and the detection platform 31 supports the shifting device 32.

[0046] The inspection platform 31 includes a platform body and an inspection hole provided on the platform body. The platform body is connected to the second conveyor belt 12 so that the end of the fixing rod of the positioning device 14 at the end of the second conveyor belt 12, away from the positioning plate, can be fixed to the platform body. The rotating platform 321 rotates, causing a pickup unit to move to the inspection hole. The position of the product picked up by the pickup unit at the inspection hole is the second inspection position 311. The second image acquisition device 22 is located below the inspection hole and takes pictures from below the product. The second image acquisition device 22 includes at least one camera, which takes pictures from directly below the product or from directly below and at least one angle below the product to capture images. The control mechanism is electrically connected to the second image acquisition device 22 to control the camera of the second image acquisition device 22. The second image acquisition device 22 transmits the captured image of the bottom surface of the product to the control mechanism, which analyzes the image of the bottom surface of the product to identify defects on the bottom surface of the product, such as whether the product is good or defective. The second detection position and the first detection position are both located on the periphery of the rotating platform 321. Relative to the center of the rotating platform 321, the second detection position and the first detection position form a certain angle. Preferably, the angle is a multiple of 45 degrees. In one embodiment, the angle between the second detection position and the first detection position is 45 degrees or 90 degrees. In this embodiment, the angle between the second detection position and the first detection position is 45 degrees.

[0047] It is understood that the inspection platform 31 can be omitted, and the second image acquisition device 22 can be positioned directly below the second inspection position 311. The second image acquisition device 22 is spaced a certain distance from the product at the second inspection position 311. The second image acquisition device 22 can automatically adjust the shooting angle and focal length of each camera, thereby enabling high-precision photography of products of different sizes and models. The second image acquisition device 22 is located around the shifting device 32, so the shifting device 32 does not obstruct the product image, achieving unobstructed photography.

[0048] The shifting device 32 includes a rotating platform 321 and at least one picking portion 322 arranged around the rotating platform 321. The rotating platform 321 includes a cylindrical platform body, an annular support frame fixed to the top of the platform body, and a fourth motor that drives the platform body to rotate. The annular support frame is used to carry at least one picking portion 322. The fourth motor drives the rotating platform 321 to rotate under the control of the control mechanism. In this embodiment, each rotation angle of the rotating platform 321 is 45 degrees. Therefore, the angle between the second detection position 311 and the first detection position 141 is set to 45 degrees, which also facilitates the rotating platform 321 to move the picking portion 322 from the first detection position 141 to the second detection position 311.

[0049] The pickup unit 322 includes a suction cup 3222 for picking up products, a vacuum generator that controls the suction force of the suction cup 3222, a solenoid valve that controls the vacuum generated by the vacuum generator, and a cylinder 3221 that controls the vertical movement of the suction cup 3222. Both the solenoid valve and cylinder 3221 are controlled by a control mechanism. Cylinder 3221 controls the vertical movement of the suction cup 3222 based on instructions from the control mechanism. The suction cup 3222 includes a flexible plate that contacts the product. This plate protects the product from damage during contact. Furthermore, the suction cup 3222 can hold products of different sizes and models, enabling the shifting device 32 to move products of different sizes and models. The solenoid valve controls the shutoff of the vacuum generator. When the solenoid valve is on, the vacuum generator generates a vacuum, and the suction cup 3222 holds the product in contact. When the solenoid valve is off, the vacuum generator stops generating a vacuum, causing the product to fall from the suction cup 3222. The cylinder 3221 controls the lifting and lowering of the tray. When a product needs to be picked up, the cylinder 3221 controls the suction cup 3222 to descend and contact the product. After the suction cup 3222 generates a vacuum under the action of the vacuum generator to absorb the product, the cylinder 3221 controls the suction cup 3222 to rise and pick up the product. The solenoid valve and the cylinder 3221 are both connected to the control mechanism. Under the control of the control mechanism, the suction cup 3222 is controlled to rise and fall as needed, and the suction cup 3222 is controlled to absorb and put down the product. In this embodiment, the shifting device 32 includes four picking parts 322, namely a first picking part, a second picking part, a third picking part, and a fourth picking part. The four picking parts are spaced 90 degrees apart from each other, and the four picking parts 322 are arranged at intervals around the annular support frame of the rotating platform 321.

[0050] The working principle of the rotation detection mechanism 30 is: Figure 3 After the first image acquisition device 21 acquires the front image of the product at the first detection position 141, the control device controls the rotating platform 321 to rotate, and the first pickup unit moves to the first detection position 141. The control mechanism controls the first pickup unit to descend, and controls the solenoid valve to turn on the suction cup 3222 of the first pickup unit to generate an adsorption force, thereby picking up the product at the first detection position 141. After that, the first pickup unit rises and returns to its original position. Figure 4 The rotating platform 321 rotates 45 degrees, causing the first pickup unit to move to the second detection position 311. At the second detection position 311, the second image acquisition device 22 acquires an image of the bottom surface of the product (because the detection hole of the detection platform 31 is located below the second detection position 311, the first pickup unit does not need to put the product down and still maintains the state of adsorbing the product). Afterwards, the control mechanism determines whether the product is a good or bad product based on the front and bottom images of the product acquired by the image acquisition device 20. Please refer to Figure 5, the rotating platform 321 continues to rotate 90 degrees, and the first picking part moves the product to the top of the stacking mechanism 40. The first picking part moves the product to the stacking platform 42 for stacking good products in the stacking mechanism 40 or the stacking platform 42 for stacking defective products. While the first picking part performs the above-mentioned inspection work, the second picking part, the third picking part and the fourth picking part follow the rear of the first picking part and repeat the above-mentioned inspection work. In this way, the four picking parts work at the same time, thereby improving the efficiency of product inspection.

[0051] See also Figure 6 The stacking mechanism 40 includes a receiving platform 41 and at least two stacking platforms 42 located below the receiving platform 41 .

[0052] The receiving platform 41 includes a receiving platform body and at least two spaced-apart through-holes disposed on the receiving platform body. Preferably, the size of the through-holes can be adjusted according to the size of the product, thereby guiding the product placed by the picking portion 322 and causing it to fall onto the stacking platform 42 below. In this embodiment, the receiving platform body of the receiving platform 41 is provided with three through-holes, namely, a first through-hole, a second through-hole, and a third through-hole.

[0053] Each of the at least two stacking platforms 42 includes a stacking platform body 421, a product stacking support 422 disposed above the stacking platform body 421, and a lifting device 423 disposed below the stacking platform body 421. The product stacking support 422 is capable of supporting products that fall from the pickup portion 322. There are at least two product stacking supports 422. In this embodiment, the product stacking supports 422 include a first product stacking support, a second product stacking support, and a third product stacking support, which are spaced 45 degrees apart from each other.

[0054] The first product stacking support is located below the first through hole, the second product stacking support is located below the second through hole, and the third product stacking support is located below the third through hole. Through the design of the linear bearing, the three product stacking supports 422 can move up and down.

[0055] The lifting devices 423 include at least two components. In this embodiment, there are three lifting devices 423, namely, a first lifting device, a second lifting device, and a third lifting device. The first lifting device controls the lifting and lowering of the first product stacking support, the second lifting device controls the lifting and lowering of the second product stacking support, and the third lifting device controls the lifting and lowering of the third product stacking support. A through-hole is formed in the stacking platform body 421 to allow the lifting devices 423 to connect to the product stacking support 422. The first, second, and third lifting devices are controlled by a first stepper motor, a second stepper motor, and a third stepper motor, respectively.

[0056] The stacking mechanism 40 operates as follows: The control mechanism controls the pickup unit 322 to drop the product onto one of the product stacking supports 422, depending on whether the product is good or defective. When a product is added to the first product stacking support, the first stepper motor controls the first product stacking support to descend a certain distance. The same applies to the second and third product stacking supports. This ensures that the products on the first, second, and third product stacking supports never become too high, allowing newly dropped products to continue to accumulate on the stacking supports. When the products on the first product stacking support reach their stacking limit and are all removed by staff, the first stepper motor controls the first product stacking support to return to its highest position. The same applies to the second and third product stacking supports.

[0057] The beneficial effects of the product inspection device 1 of the present invention are: first, the rotating detection mechanism 30 can automatically move the product, and the image acquisition device 20 can automatically detect the product, so the product inspection device 1 of the present invention can realize automatic defect detection, fast detection speed, and reduced cost; second, the product image is obtained and identified by the image acquisition device 20, which is relatively accurate, avoiding the problem of high error rate of defect identification by the human eye; third, the product inspection device 1 includes a first detection position 141 and a second detection position 311, which can detect the front and back of the product, thereby improving the comprehensiveness of the detection; fourth, the picking part 322 can be multiple, and multiple picking parts 322 work simultaneously, further improving the detection speed; and fifth, by adjusting the first angle between the first rocker arm 112 and the first conveyor belt body 111 The second angle between the second rocker arm 113 and the first conveyor belt body 111 can be used to align products of different sizes; the width adjustment device 13 can arrange products of different sizes in sequence along a straight line by adjusting the distance between the first limit rod 131 and the second limit rod 132, which is convenient for the picking up of the rotating detection mechanism 30. The picking part of the rotating detection mechanism 30 can pick up products of different sizes and models through its suction cup 3222. Therefore, the product inspection device 1 of the present invention can perform defect detection on products of different sizes and models; Sixth, the first detection position and the second detection position are both located around the rotating detection mechanism 30. During the process of shooting the product by the first image acquisition device and the second image acquisition device, they are not blocked by the rotating detection mechanism 30, and can realize unobstructed product inspection with high detection accuracy.
