Description

Technical Field

[0001] This utility model relates to the field of detection device technology, and in particular to a visual inspection mechanism and a coding device for tinplate printed products. Background Technology

[0002] Tinplate generally refers to cold-rolled low-carbon steel sheets with a thin layer of tin plating on the surface. It possesses good sealing properties, corrosion resistance, and ductility, and is commonly used to make packaging containers such as food cans, beverage cans, and gift boxes. To give the packaging containers an attractive appearance and clearly convey product information to consumers, printing is usually required on the tinplate used for packaging containers. To ensure printing quality, visual inspection of the printed tinplate is necessary.

[0003] Chinese patent document CN219737278U discloses a tinplate color printing inspection device. This device has the functions of visual defect and gloss detection, and can easily switch between the two functions as needed. However, the visual inspection camera will cause the temperature to rise due to prolonged operation, and the existing tinplate color printing inspection device does not have a heat dissipation function for the visual inspection camera. If the visual inspection camera cannot dissipate heat in time, it will reduce the speed of the visual inspection camera in recognizing and processing images, and cannot guarantee that the accuracy of the tinplate printed product inspection results remains at a high level. Utility Model Content

[0004] The purpose of this invention is to provide a visual inspection mechanism and a coding device for tinplate printed products, aiming to solve the problem that existing tinplate color printing inspection devices do not have a heat dissipation function for visual inspection cameras.

[0005] To achieve the above objectives, the solution provided by this utility model is as follows: The first aspect of this utility model provides a visual inspection mechanism, including a longitudinal beam and a visual inspection camera; it also includes a fixing component, a cooling fan, and an L-shaped connector; Both the visual inspection camera and the L-shaped connector can be detachably mounted on the fixing assembly; the cooling fan is fixedly mounted on the L-shaped connector, with the air intake of the cooling fan facing the visual inspection camera, and the air outlet of the cooling fan located at the top of the cooling fan or on the side of the cooling fan facing away from the visual inspection camera.

[0006] Optionally, the L-shaped connector includes a horizontal connecting part and a vertical connecting part; the cooling fan is fixed on the vertical connecting part; A first oblong hole is provided on the horizontal connecting part along the direction parallel to the length of the longitudinal beam, and a first screw is vertically inserted into the first oblong hole; the lower end of the first screw is fixed to the fixing component, and a first nut is threaded onto the first screw; the first nut presses against the horizontal connecting part.

[0007] Optionally, the fixing assembly includes a bracket and a slide block fixedly connected to the bracket; a slide rail parallel to the longitudinal beam is fixed on the longitudinal beam; the slide block is slidably disposed on the slide rail; The slide rail is fixed at both ends with support plates, and an adjusting screw is rotatably provided on the support plates; the slide block is sleeved on the adjusting screw, and the slide block and the adjusting screw are threadedly connected.

[0008] Optionally, a handwheel is connected to the end of the adjusting screw.

[0009] Optionally, the slide rail is provided in two sets, and the two sets of slide rails are fixed to the longitudinal beam in a mirror image; each set of slide rails includes two single rails arranged vertically, and each set of slide rails is slidably provided with a slide block.

[0010] Optionally, the bracket includes a first horizontal plate fixedly connected to the slide, a second screw that is vertically and fixedly inserted through the first horizontal plate, and a second horizontal plate movably sleeved on the second screw. The second horizontal plate is located above the first horizontal plate; the visual inspection camera and the L-shaped connector can both be detachably mounted on the second horizontal plate.

[0011] Optionally, the bracket further includes a third horizontal plate movably sleeved on the second screw; the third horizontal plate is located below the first horizontal plate, and the third horizontal plate is fixedly connected to a supplementary lighting component; the supplementary lighting component is located below the visual inspection camera.

[0012] Optionally, the supplementary lighting assembly includes a housing with light-transmitting plates on both the upper and lower sides, and a light source fixed inside the housing.

[0013] The second aspect of this utility model provides a coding device for tinplate printed products, including a conveying mechanism and a coding terminal disposed above the conveying mechanism; it also includes the aforementioned visual inspection mechanism; the visual inspection mechanism is fixedly mounted above the conveying mechanism and is located downstream of the coding terminal.

[0015] Beneficial effects: The first aspect of this utility model provides a visual inspection mechanism. By fixing a visual inspection camera onto a fixed component and using an L-shaped connector fixed to the fixed component to install a cooling fan, the air intake of the cooling fan can face the visual inspection camera, allowing direct air intake and cooling of the working visual camera. This quickly removes the heat generated by the visual inspection camera, preventing the image recognition and processing speed from decreasing due to overheating. At the same time, the air outlet of the cooling fan is located on the top of the fan or on the side away from the visual inspection camera, preventing the exhausted hot air from blowing back onto the visual inspection camera and affecting the cooling effect, and also preventing interference with the visual inspection field of view of the visual inspection camera. This effectively ensures that the visual inspection camera can always work efficiently, ensuring that the accuracy of the inspection results of tinplate printed products remains at a high level.

[0016] The second aspect of this invention provides a coding device for tinplate printed products. By setting the visual inspection mechanism downstream of the coding terminal, the coding quality of the tinplate printed products can be immediately detected by the visual inspection mechanism after coding is completed at the coding terminal. This allows for the timely detection of problems such as blurry coding and missed coding, preventing unqualified products from flowing into subsequent stages and ensuring product quality. Moreover, the visual inspection mechanism, the conveying mechanism 13, and the coding terminal form a continuous production and inspection process, which can reduce intermediate transfer links of tinplate printed products and improve overall production and inspection efficiency.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in the embodiments of this utility model are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0027] It should also be noted that when a component is described as "fixed to" or "set on" another component, it can be directly on the other component or there may be an intervening component present. When a component is described as "connected to" another component, it can be directly connected to the other component or there may be an intervening component present.

[0028] Furthermore, the use of terms such as "first" and "second" in this utility model is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0029] Please see Figures 1 to 6 The first aspect of this utility model provides a visual inspection mechanism, which can be installed above a conveying mechanism 13 for conveying thin metal sheets, thereby enabling visual inspection of tinplate printed products or other types of thin metal sheets. Specifically, the visual inspection mechanism includes a longitudinal beam 1, a visual inspection camera 2, a fixing component 3, a cooling fan 4, and an L-shaped connector 5.

[0030] The visual inspection camera 2 is fixedly mounted on the fixing component 3 with screws; one side of the L-shaped connector 5 is fixed to the fixing component 3, and the other side of the L-shaped connector 5 is fixedly connected to the cooling fan 4 with screws. The air intake 401 of the cooling fan 4 faces the visual inspection camera 2, and the air outlet of the cooling fan 4 is located on the top of the cooling fan 4 or on the side of the cooling fan 4 facing away from the visual inspection camera 2.

[0031] This invention fixes the visual inspection camera 2 onto the fixing component 3 and uses the L-shaped connector 5 fixed to the fixing component 3 to install the cooling fan 4. This allows the air intake 401 of the cooling fan 4 to face the visual inspection camera 2, directly drawing air to cool the working visual camera and quickly removing the heat generated by the visual inspection camera 2. This prevents the visual inspection camera 2 from reducing its image recognition and processing speed due to increased temperature. At the same time, the air outlet of the cooling fan 4 is located on the top of the fan or on the side away from the visual inspection camera 2, so that the exhausted hot air will not blow back onto the visual inspection camera 2, affecting the heat dissipation effect, nor will it interfere with the visual inspection field of the visual inspection camera 2. This effectively ensures that the visual inspection camera 2 can always work efficiently and ensures that the accuracy of the inspection results of tinplate printed products remains at a high level.

[0032] For example, the vision camera may be a Hikvision MV-CE100-30GM industrial camera.

[0033] like Figure 2 and Figure 3As shown, in an optional embodiment, the L-shaped connector 5 includes a horizontal connecting portion 501 and a vertical connecting portion 502; the cooling fan 4 is fixed on the vertical connecting portion 502. The length direction of the horizontal connecting portion 501 is parallel to the length direction of the longitudinal beam 1, and a first oblong hole 5011 is provided on the horizontal connecting portion 501 along a direction parallel to the length direction of the longitudinal beam 1. A first screw 6 is vertically inserted into the first oblong hole 5011; the lower end of the first screw 6 is fixed on the fixing component 3, and a first nut 7 is threaded onto the first screw 6; the first nut 7 presses against the horizontal connecting portion 501. In this embodiment, by opening a first oblong hole 5011 on the horizontal connecting part 501 and cooperating with the first screw 6 passing through the first oblong hole 5011, the position of the L-shaped connector 5 on the fixing component 3 can be flexibly adjusted along the length direction of the first oblong hole 5011 when the first nut 7 is loosened, thereby adjusting the relative distance between the cooling fan 4 and the vision inspection camera 2, ensuring that the heat dissipation effect is adapted to the actual heat generation of the vision inspection camera 2; at the same time, after tightening the first nut 7, the horizontal connecting part 501 can be firmly fixed on the fixing component 3, ensuring the stability of the cooling fan 4 when it is working.

[0034] like Figure 1 As shown, in an optional embodiment, the fixing component 3 includes a bracket 31 and a slide block 32 fixedly connected to the bracket 31; a slide rail 8 parallel to the longitudinal beam 1 is fixed on the longitudinal beam 1; the slide block 32 is slidably disposed on the slide rail 8; support plates 9 are fixed at both ends of the slide rail 8, and an adjusting screw 10 is rotatably disposed on the support plate 9; the slide block 32 is sleeved on the adjusting screw 10, and the slide block 32 is threadedly connected to the adjusting screw 10. In this embodiment, rotating the adjusting screw 10 can drive the slide block 32 to move along the slide rail 8, thereby driving the bracket 31 and the vision inspection camera 2 on the bracket 31 to move synchronously, thereby realizing the fine adjustment of the vision inspection camera 2 along the length direction of the longitudinal beam 1, so as to flexibly adapt to the inspection needs of tinplate printed products of different sizes.

[0035] like Figure 1 As shown, in an optional embodiment, a handwheel 11 is connected to the end of the adjusting screw 10, which allows the operator to rotate the adjusting screw 10 using the handwheel 11.

[0036] like Figure 1 As shown, in an optional embodiment, the slide rails 8 are provided in two sets, and the two sets of slide rails 8 are fixed to the longitudinal beam 1 in mirror image; each set of slide rails 8 includes two single rails arranged vertically, and each set of slide rails 8 is slidably provided with a slide block 32. Since the slide blocks 32 can be fixedly connected to the bracket 31 to assemble into a fixed component 3, the visual inspection mechanism provided by this utility model can be equipped with two sets of visual inspection cameras 2, which can flexibly adapt to the synchronous inspection needs of tinplate printed products of different specifications on the same conveying mechanism 13.

[0037] like Figure 2 and Figure 3 As shown, in an optional embodiment, the bracket 31 includes a first horizontal plate 321 fixedly connected to the slide 32, a second screw 322 vertically and fixedly passing through the first horizontal plate 321, and a second horizontal plate 323 movably sleeved on the second screw 322. Specifically, the length directions of both the second horizontal plate 323 and the first horizontal plate 321 are perpendicular to the length direction of the longitudinal beam 1, and the second horizontal plate 323 is located above the first horizontal plate 321; the visual inspection camera 2 and the L-shaped connector 5 are both detachably mounted on the second horizontal plate 323. To ensure that the second horizontal plate 323 is fixedly sleeved on the second screw 322, nuts are sleeved on the second screw 322 both above and below the second horizontal plate 323. The nuts press against the surface of the second horizontal plate 323. In this embodiment, the second horizontal plate 323 is movably sleeved on the second screw 322 and fixed by nuts located on the upper and lower sides of the second horizontal plate 323; when the nuts are loosened, the height of the second horizontal plate 323 on the second screw 322 can be flexibly adjusted, thereby realizing the adjustment of the height of the vision inspection camera 2 and the L-shaped connector 5, thus enabling the vision inspection mechanism to adapt to the inspection needs of tinplate printed products of different thicknesses.

[0038] like Figure 2 and Figure 3 As shown, in an optional embodiment, the bracket 31 further includes a third horizontal plate 324 movably sleeved on the second screw 322; the third horizontal plate 324 is located below the first horizontal plate 321, and a supplementary lighting component 12 is fixedly connected to the third horizontal plate 324; the supplementary lighting component 12 is located below the visual inspection camera 2. To ensure the third horizontal plate 324 is fixedly sleeved on the second screw 322, nuts are sleeved on both above and below the third horizontal plate 324, with the nuts pressing against the surface of the third horizontal plate 324.

[0039] The supplementary lighting component 12 is located below the visual inspection camera 2, providing sufficient and uniform light to the camera's inspection area. This effectively improves the problem of blurred image recognition caused by insufficient light, enhancing the accuracy of tinplate printing product inspection results. The third horizontal plate 324 can be flexibly adjusted in height along the second screw 322 by tightening and loosening the nut, thereby driving the supplementary lighting component 12 to rise and fall synchronously. This allows for adjusting the supplementary lighting height to achieve the best lighting effect based on the light requirements of tinplate printing products of different thicknesses or different inspection scenarios. It also matches the height adjustment of the visual inspection camera 2 on the second horizontal plate 323, ensuring that the supplementary lighting range always precisely matches the inspection field of view of the visual inspection camera 2.

[0040] like Figure 4As shown, in an optional embodiment, the supplementary lighting assembly 12 includes a housing 122 with light-transmitting plates 121 on both the upper and lower sides, and a light source 123 fixed inside the housing 122. The light source 123 can be a surface light source 123. In this embodiment, the housing 122 effectively protects the internal light source 123, preventing external dust from contacting the light source 123 during the detection process, reducing the risk of damage to the light source 123, and extending the service life of the light source 123. The light-transmitting plates 121 on the upper and lower sides allow the light emitted by the light source 123 to be emitted evenly in both directions. This provides sufficient and soft illumination for the visual inspection camera 2 located above the supplementary lighting component 12, improving the clarity and detail of the images captured by the visual inspection camera 2, while also reducing light waste and ensuring that the illumination coverage matches the detection field of view of the visual inspection camera 2. At the same time, the design of the housing 122 and the light-transmitting plates 121 can also concentrate the light to a certain extent and enhance the local illumination intensity. Even in scenes with low ambient light, it can provide stable illumination conditions for detection, further maintaining the efficient working state of the visual inspection camera 2.

[0041] like Figure 5 and Figure 6 As shown, the second aspect of this utility model provides a coding device for tinplate printed products, including a conveying mechanism 13 and a coding pad disposed above the conveying mechanism 13; it also includes the aforementioned visual inspection mechanism; the visual inspection mechanism is fixedly mounted above the conveying mechanism 13 and is located downstream of the coding pad.

[0042] In the coding device for tinplate printed products provided by this utility model, by setting the visual inspection mechanism downstream of the coding terminal, the coding quality of the tinplate printed products can be immediately detected by the visual inspection mechanism after coding is completed at the coding terminal. This can promptly detect problems such as blurry coding and missed coding, prevent unqualified products from flowing into subsequent stages, and ensure product quality. Moreover, the visual inspection mechanism, the conveying mechanism 13, and the coding terminal form a continuous production and inspection process, which can reduce intermediate transfer links of tinplate printed products and improve the overall production and inspection efficiency.

[0043] For example, the spray nozzle 14 may be a spray nozzle provided by Shanghai Shanghao Digital Technology Co., Ltd.

[0044] In an optional embodiment, a housing 15 is fixedly mounted above the conveying mechanism 13; the vision inspection mechanism is fixed inside the housing 15 by a longitudinal beam 1; the top of the housing 15 is provided with an exhaust vent, and an exhaust fan 16 is installed inside the exhaust vent; a door 17 is connected to the side hinge of the housing 15. In this embodiment, the housing 15 provides a closed protective space for the internal vision inspection mechanism, effectively preventing external dust from contacting the vision inspection mechanism, extending the service life of the vision inspection mechanism, and avoiding interference from changes in ambient light on the imaging accuracy of the vision inspection camera 2, thus ensuring inspection stability; while the exhaust fan 16 inside the exhaust vent at the top of the housing 15 can promptly expel the hot air accumulated inside the housing 15, forming an air circulation channel, further improving heat dissipation efficiency, and preventing the temperature inside the housing 15 from being too high and affecting the working performance of the various components of the vision inspection mechanism.

[0045] The door 17, connected by a hinge on the side of the chassis 15, is easily opened by the operator to adjust the position of the internal vision inspection mechanism or to perform maintenance.

[0046] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
