Description

Technical Field

[0001] This utility model relates to the field of empty barrel detection technology, and in particular to an insert-type plastic empty barrel bottom detection device. Background Technology

[0002] Bottled water is an indispensable daily necessity in homes and offices. Based on the principles of environmental protection and safe use, current bottled water manufacturers are proposing to use recyclable plastic containers. When collecting empty containers, manufacturers are required to conduct strict cleaning and disinfection before reuse, thereby achieving the recycling of empty containers, saving materials, and reducing costs.

[0003] To conduct scientific and rigorous testing of the cleanliness of empty containers, visual inspection technology is often used to check the cleanliness of the inside of the containers. Among these tests, the inspection of the bottom of the empty container is of paramount importance in the entire inspection process.

[0004] However, current solutions for inspecting the bottom of plastic buckets involve placing a visual inspection camera above the empty plastic bucket to take pictures of the bottom from the outside. However, the entrance to an empty plastic bucket usually has a long inlet, which limits the imaging range of the visual inspection camera, resulting in incomplete bottom images and affecting the accuracy of the inspection.

[0005] Therefore, in order to improve the accuracy of barrel bottom detection, it is necessary to provide a new type of plastic empty barrel bottom detection device. Utility Model Content

[0022] To provide a more detailed description of this utility model, the following description is provided in conjunction with the accompanying drawings. It should be noted that the embodiments described below are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0023] refer to Figure 1 As shown, an insertable plastic empty barrel bottom inspection device is used to visually inspect the bottom of a cleaned plastic empty barrel to obtain the cleanliness of the bottom. The inspection device includes a frame 1, on one side of which a conveying mechanism 2 and a support 3 are sequentially arranged along the direction away from the ground.

[0024] Specifically, refer to Figure 1 and Figure 2 As shown, the support 3 is equipped with at least one barrel bottom detection mechanism 4. In this embodiment, the support 1 is equipped with four barrel bottom detection mechanisms 4, and the barrel bottom detection mechanisms 4 are arranged equidistantly on the support 3 along the conveying direction of the conveying mechanism 2, so that the cleanliness of the bottom of four empty plastic barrels 0 can be detected at the same time.

[0025] The barrel bottom detection mechanism 4 is located directly above the conveying mechanism 2, and the barrel bottom detection mechanism 4 includes a lifting assembly and a visual inspection camera 41 for detecting the bottom of the empty plastic barrel 0; the lifting assembly includes a lifting cylinder 42 mounted on the bracket, a first piston rod 43 and a lifting seat 44, the lifting cylinder 42 is connected to the lifting seat 44 through the first piston rod 43; the visual inspection camera 41 is disposed on the lifting seat 44.

[0026] The conveying mechanism 2 is used to convey the empty plastic barrel 0 to the area directly below the corresponding visual inspection camera 41; the lifting cylinder 42 is used to drive the first piston rod 43 to lift the lifting seat 44, thereby inserting the lens of the visual inspection camera 41 into the inlet of the empty plastic barrel 0 directly below.

[0027] refer to Figure 2 and Figure 4 As shown, the empty plastic bucket 0 is conveyed by the conveying mechanism 2 to a position directly below the corresponding visual inspection camera 41. Then, the lifting cylinder 42 drives the first piston rod 23 to raise and lower the lifting seat 44, causing the visual inspection camera 41 to rise and fall in a direction perpendicular to the conveying mechanism 2. When the empty plastic bucket reaches the preset position of the conveying mechanism 2, i.e., when the inlet of the empty plastic bucket 0 is directly below the lens of the visual inspection camera 41, the lens of the visual inspection camera 41 on the lifting seat 44 descends vertically with the lifting seat 44 and inserts into the inlet of the empty plastic bucket directly below, so that the image range acquired by the visual inspection camera 41 is as shown... Figure 4 The enlarged view shown allows for the acquisition of full-range images of the bottom of the empty plastic bucket 0 for visual inspection, enabling comprehensive inspection of the bottom of the empty plastic bucket 0. This improves the accuracy of empty plastic bucket 0 inspection and enhances the efficiency and quality of cleanliness inspection for the recycling of empty plastic bucket 0.

[0028] The conveying mechanism 2 includes a conveying frame 21 and a conveyor belt 22 disposed on the conveying frame 21, and a motor 23 for driving the conveyor belt 22 to rotate is provided at one end of the conveying frame 21.

[0029] In this embodiment, the conveyor belt 22 is a transparent conveyor belt, and a plurality of planar light sources 6 are provided on one side of the frame 1, and the planar light sources 6 are arranged sequentially below the transparent conveyor belt.

[0030] The transparent conveyor belt, together with the bottom planar light source, forms a transmissive lighting environment. When the empty plastic bucket passes by, the planar light source provides good illumination to the bottom structure of the bucket through the transparent conveyor belt, enabling the visual inspection camera 41 inserted into the bucket opening to obtain a clearer image of the bottom of the bucket for inspection, thereby improving the efficiency and quality of inspection.

[0031] refer to Figure 2 and Figure 3 As shown, the conveying mechanism 2 also includes a photoelectric switch 24 disposed at the inlet end of the conveyor belt 22 and a limiting mechanism 25 disposed on the conveyor frame 21 on the side away from the inlet end; the photoelectric switch 24 is used to detect the plastic empty bucket 1 entering the conveyor belt 22; the limiting mechanism 25 is used to stop the movement of the plastic empty bucket 0 on the conveyor belt.

[0032] When the empty plastic bucket 0 begins to enter the conveyor belt 22, the photoelectric switch 24 is triggered, and the system can start timing. After a preset time, the conveying can be paused, thereby driving the bucket bottom detection mechanism 4 to acquire and detect the bottom image of the empty plastic bucket 0. Simultaneously with the pause in conveying, the limiting mechanism stops the movement of the empty plastic bucket 0 to be detected on the conveyor belt that is directly opposite the limiting mechanism 25, and prevents subsequent empty plastic buckets to be detected from moving slightly, or stops the movement of multiple empty plastic buckets 0 to be detected on the conveyor belt that are directly opposite the limiting mechanism 25. This avoids the situation where slight displacement of the empty plastic bucket 0 after the conveying is paused causes the inlet of the empty plastic bucket 0 to be misaligned with the lens of the visual inspection camera 41, making lens insertion difficult, thus achieving accurate positioning of the empty plastic bucket during the conveying process.

[0033] With the cooperation of photoelectric switch 24 and limiting mechanism 25, the conveyor belt 22 can be paused after the preset time when the photoelectric switch 24 is triggered to allow the empty plastic barrel 0 to enter the conveyor belt. At this time, a certain empty plastic barrel 0 has reached the position in front of the limiting mechanism 25. The limiting mechanism 25 stops the movement of the empty plastic barrel 0 that has reached the position in front of the limiting mechanism 25, ensuring that the inlet of the empty plastic barrel 0 is directly facing the lens of the corresponding visual inspection camera 41, so that the lens can be inserted into the inlet of the empty plastic barrel 0 to obtain inspection images.

[0034] The limiting mechanism 25 includes a stop cylinder 251 and a first limiting guardrail 252 disposed on one side of the conveyor frame 21; the stop cylinder 251 is connected to a limiting plate 254 via a second piston rod 253; and the first limiting guardrail 252 is disposed on the other side of the conveyor frame 21 and is disposed opposite to the limiting plate 254; and the stop cylinder 251 is used to drive the second piston rod 253 to move the limiting plate 254 along the direction close to the first limiting guardrail 252.

[0035] The stop cylinder 251 drives the second piston rod 253 to move the limiting plate 254 along the direction close to the first limiting guardrail 252, so that the empty plastic bucket 0 can be limited and fixed on the limiting plate 254 and the first limiting guardrail 252, thus achieving the stationary state of the empty plastic bucket.

[0036] A second limiting guardrail 5 is also provided on the side of the conveyor frame 21 opposite to the first limiting guardrail 252. The second limiting guardrail 5 is arranged along the length direction of the conveyor belt 22 and is located above the stop cylinder 251.

[0037] The first limiting guardrail 252 and the second limiting guardrail 5 limit the position of the empty plastic bucket 0 on the conveyor belt 22, effectively preventing accidental drops or collisions during transport and improving the stability of the transport process. The second limiting guardrail 5 is located above the stop cylinder 251, while the first limiting guardrail 252 is positioned opposite to it. This creates a height difference between the first limiting guardrail 252 and the second limiting guardrail 5, better accommodating empty plastic buckets 0 of different sizes and ensuring stable support and positioning during transport.

[0038] The working principle of this utility model is as follows: When a single empty plastic bucket enters, the photoelectric switch 24 is triggered when the empty plastic bucket 0 begins to enter the transparent conveyor belt, and the system starts timing; after a predetermined time, when the empty plastic bucket 0 reaches the designated position, the conveyor belt 22 stops conveying, and the second piston rod 253 is driven by the stop cylinder 251 to move the limiting plate 254 along the direction close to the first limiting guardrail 252, so that the empty plastic bucket 0 can be limited and fixed on the limiting plate 254 and the first limiting guardrail 252, fixing the empty plastic bucket 0. The lifting cylinder 42 on the empty plastic bucket 0 drives the first piston rod 23 to move the lifting seat 44 up and down, so that the visual inspection camera 41 descends along the direction perpendicular to the conveying mechanism 2 until it is inserted into the empty plastic bucket 0. At the same time, the planar light source 6 at the bottom lights up, and the visual inspection camera 41 takes a picture to obtain the inspection image. After that, the stop cylinder 251 retracts the limiting plate 254, and the empty plastic bucket 0 moves downwards in the inspection process; the above process is repeated after the next empty plastic bucket 0 enters and triggers the photoelectric switch 24.

[0039] When multiple empty plastic barrels 0 enter, they are grouped according to the number of vision inspection cameras 41. When the first empty plastic barrel 0 triggers the photoelectric switch 24, the system starts timing. After a predetermined time, each empty plastic barrel 0 reaches the designated position, the conveyor belt 22 stops conveying, and the movement of the empty plastic barrel 0 is stopped by the limit mechanism 25, so that the empty plastic barrel 0 is fixed in the corresponding position. At this time, the vision inspection camera 41 above is inserted into the inlet of the corresponding empty plastic barrel 0 for inspection.

[0040] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model and do not limit the utility model to the specific implementations described. Obviously, other modifications and variations can be made based on the content of this specification. The embodiments selected and specifically described in this specification are intended to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. They are not intended to limit the utility model, and any simple modifications to this utility model fall within the protection scope of this utility model.
