DETAILED DESCRIPTION

[0038] The present application is described below based on the following embodiments, but the present application is not limited to these embodiments. In the detailed description of the present application below, certain specific details are described in detail. Those skilled in the art can fully understand the present application without the description of these details. To avoid obscuring the essence of the present application, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0039] Furthermore, persons of ordinary skill in the art will appreciate that the figures provided herein are for illustration purposes only and are not necessarily drawn to scale.

[0040] Unless otherwise specified or limited, the terms "mounted," "connected," "connect," "fixed," and the like should be interpreted broadly. For example, they may refer to fixed or detachable connections, or integration; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components or interaction between two components, unless otherwise specified. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0041] Unless the context clearly requires otherwise, words like “include”, “comprising” and the like throughout this application should be interpreted as including rather than exclusive or exhaustive; that is, as meaning “including but not limited to”.

[0042] In the description of this application, it should be understood that the terms "first", "second", etc. are used for descriptive purposes only and should not be understood to indicate or imply relative importance. In addition, in the description of this application, unless otherwise specified, "plurality" means two or more.

[0043] Figure 1 and Figure 2 Schematic diagram of the structure of the detection platform of this embodiment. Figure 1 and Figure 2 As shown, the detection platform includes a bearing plate 1, a rotating mounting plate 2, multiple rotating shafts 3, multiple carrier blocks 4, a positioning plate 5 (as shown in FIG. Figure 4 ), first rotary driver 6, and second rotary driver 7. The rotating mounting plate 2 is rotatably connected to the carrier plate 1 at both ends. Multiple rotating shafts 3 are movably connected to the rotating mounting plate 2. Multiple carrier blocks 4 are respectively disposed at the top ends of the multiple rotating shafts 3. A positioning plate 5 is mounted on the carrier plate 1 and located on one side of the rotating mounting plate 2. Each carrier block 4 is used to absorb and secure a product to be inspected.

[0044] The first rotary driver 6 is used to drive the rotary mounting plate 2, along with the multiple rotating shafts 3 and the multiple carrier blocks 4, to rotate simultaneously about the first axial direction to a predetermined angle, so that the product to be inspected contacts the positioning plate. The first rotary driver 6 then controls the carrier blocks 4 to stop adsorption, allowing the product to separate from the carrier blocks 4 and fall onto the positioning plate 5, thereby exposing the bottom surface of the product to be inspected. This exposed bottom surface facilitates bottom surface inspection of the product by the visual inspection component.

[0045] The second rotary driver 7 is connected to the multiple rotating shafts 3. The second rotary driver 7 drives the multiple rotating shafts 3 to drive the multiple carriers 4 to rotate around the central axis of the rotating shaft 3 at the same time, so that the multiple adsorbed products to be inspected can rotate synchronously, so that the visual inspection component can simultaneously inspect the four sides and top surface of the multiple products to be inspected.

[0046] Therefore, under the action of the first rotary driver 6 and the second rotary driver 7, the six surfaces of the product to be inspected can be directed towards or located within the monitoring range of the visual inspection component, thereby realizing the inspection of the six surfaces of the product to be inspected, maximizing the use of the visual inspection component, greatly saving costs, and being able to inspect multiple products to be inspected at one time, thereby improving work efficiency.

[0047] like Figure 3 and Figure 4As shown, the supporting plate 1 includes a support platform 11 and two support frames 12. The two support frames 12 are vertically fixed on both sides of the support platform 11, and the two support frames 12 are symmetrically arranged. The rotating mounting plate 2 is rotatably connected between the two support frames 12, so that the rotating mounting plate 2 and the multiple rotating shafts 3, multiple carrier blocks 4, and the second rotating driver 7 arranged thereon can rotate simultaneously. That is, the supporting plate 1 is used to provide support for the rotating mounting plate 2 and the components thereon. Among them, when the rotating mounting plate 2 is rotatably connected between the two support frames 12, the height of the rotating mounting plate 2 to the support platform 11 can meet the rotation and passage of the highest position component thereon.

[0048] like Figure 6 As shown, the rotating mounting plate 2 includes a first mounting plate 21, a second mounting plate 22, a first connecting plate 23 and a second connecting plate 24, and the first mounting plate 21, the first connecting plate 23, the second mounting plate 22 and the second connecting plate 24 are connected end to end in sequence. Among them, the first mounting plate 21 and the second mounting plate 22 are parallel to each other, and the first connecting plate 23 and the second connecting plate 24 are parallel to each other and perpendicular to the first mounting plate 21 and the second mounting plate 22. Connecting shafts 25 are fixedly installed on the outer sides of the first connecting plate 23 and the second connecting plate 24 respectively. The rotating mounting plate 2 is rotatably connected to the two support frames 12 through two connecting shafts 25 on both sides. Among them, the two connecting shafts 25 are coaxially arranged to ensure that the rotating mounting plate 2 can rotate around the central axis (i.e., the first axial direction) of the connecting shaft 25. The central axis of the connecting shaft 25 is arranged parallel to the first mounting plate 21 and the second mounting plate 22.

[0049] It should be noted that the two connecting shafts 25 and the two supporting frames 12 can be rotatably connected via bearings to reduce friction when the connecting shafts 25 rotate.

[0050] The first rotary actuator 6 is mounted on the outside of the support frame 12 and connected to the connecting shaft 25 on the corresponding side, thereby enabling the first rotary actuator 6 to drive the rotary mounting plate 2 to rotate. In this embodiment, the first rotary actuator 6 can be a motor, which can be used with a reducer as needed to drive the rotary mounting plate 2 to rotate, thereby satisfying the purpose of turning the product to be inspected over and exposing the bottom surface of the product to be inspected for inspection.

[0051] The plurality of rotating shafts 3 are movably connected to the rotating mounting plate 2. That is, the plurality of rotating shafts 3 are rotatably arranged on the rotating mounting plate 2. Optionally, the plurality of rotating shafts 3 are rotatably connected to the rotating mounting plate 2 through bearings, which can reduce the friction when the rotating shafts 3 rotate.

[0052] In this embodiment, a plurality of mounting holes 26 are provided on the first mounting plate 21 and the second mounting plate 22, and the mounting holes 26 provided above and below are coaxially arranged. Figure 6 As shown. Two bearings 33 are provided on the rotating shaft 3. Figure 5As shown. When the rotating shaft 3 is mounted on the rotating mounting plate 2, the two bearings 33 thereon engage with the mounting holes 26 of the first mounting plate 21 and the second mounting plate 22, respectively, to achieve connection. The ends of the rotating shaft 3 extend from the top of the first mounting plate 21 and the bottom of the second mounting plate 22, respectively. In this embodiment, multiple rotating shafts 3 are arranged in a row. In other embodiments, the multiple rotating shafts 3 can also be staggered.

[0053] Among them, multiple rotating shafts 3 are connected to each other through synchronous belts 31, and one of the synchronous belts 31 is connected to the second rotating driver 7. The second rotating driver 7 drives the multiple rotating shafts 3 to rotate synchronously through the multiple synchronous belts 31. In other words, the second rotating driver 7 first drives two rotating shafts 3 to rotate synchronously through the synchronous belts 31, and the two rotating shafts 3 respectively drive the rotating shaft 3 next to them to rotate through another synchronous belt 31, and the transmission is sequentially transmitted, thereby achieving the synchronous rotation of multiple rotating shafts 3. Figure 5 shown.

[0054] In this embodiment, two synchronous pulleys 32 are provided on each rotating shaft 3. Figure 5 As shown. A synchronous belt 31 connects two synchronous pulleys 32 located at the same height of two adjacent rotating shafts 3. Multiple synchronous belts 31 are staggered up and down, thereby allowing multiple rotating shafts 3 to achieve synchronous rotation through the sequential transmission of the synchronous belts 31. Among them, the upper synchronous pulley 32 is located between two bearings 33. After the rotating shaft 3 is installed on the rotating mounting plate 2, the upper synchronous pulley 32 is located between the first mounting plate 21 and the second mounting plate 22, and the lower synchronous pulley 32 is located below the second mounting plate 22. The above installation and setting method can reduce the overall size of the structure and avoid the rotating mounting plate 2 being installed too high.

[0055] In this embodiment, the second rotary driver 7 is fixed to the second mounting plate 22 and is driven and connected to two of the rotating shafts 3 via a synchronous belt 31. Optionally, the second rotary driver 7 is driven and connected to the two rotating shafts 3 located in the middle position via a synchronous belt 31, so that when the middle rotating shaft 3 transmits power to the two sides, the transmission speed is increased, thereby improving the speed and stability of the simultaneous rotation of multiple rotating shafts 3.

[0056] In this embodiment, the second rotation driver 7 can be a motor, which can be used with a reducer as needed. The power is transmitted through the synchronous belt 31 to enable the synchronous rotation of multiple rotating shafts 3, and the synchronous rotation of multiple carriers 4 is achieved, so that the four sides of the product to be inspected can be inspected.

[0057] Furthermore, the detection platform also includes a plurality of adjustment followers 8 and a plurality of adjustment blocks 9, such as Figure 3As shown in the figure, the number of adjustment followers 8 matches the number of adjustment blocks 9, and is the same as the number of synchronous belts 31. The adjustment followers 8 are provided in a one-to-one correspondence with the synchronous belts 31 and are used to adjust the tension of the synchronous belts 31. The adjustment blocks 9 are connected to the adjustment followers 8 and are used to push the adjustment followers 8 to adjust the synchronous belts 31.

[0058] In this embodiment, the adjustment follower 8 includes a moving block 81, an adjustment wheel 82 and a fastener 83. Figure 7 As shown. The adjusting wheel 82 is rotatably connected to the moving block 81, and the adjusting wheel 82 is located on one side of the synchronous belt 31. The moving block 81 is movably set on the rotating mounting plate 2, and is used to move with the adjusting wheel 82 so that the adjusting wheel 82 contacts the synchronous belt 31 to adjust the tension of the synchronous belt 31. After the tension of the synchronous belt 31 is adjusted, the moving block 81 is locked to the rotating mounting plate 2 by the fastener 83. The adjusting block 9 is located on the outside of the moving block 81 and is connected to the moving block 81 by the connecting rod 10. The adjusting block 9 pushes the moving block 81 and the adjusting wheel 82 to move through the connecting rod 10 to adjust the tension of the synchronous belt 31.

[0059] Specifically, a plurality of adjustment holes 221 and a plurality of movement holes 222 are provided on the rotating mounting plate 2 (ie, the second mounting plate 22). Figure 6 As shown. The moving block 81 includes a positioning boss 811, which is movably disposed within the adjustment hole 221. The fastener 83 passes through the movable hole 222 and is fixedly connected to the moving block 81. The adjustment hole 221 and the movable hole 222 are both waist-shaped holes, allowing the moving block 81 to move and adjust the position of the adjustment wheel 82, and allowing the fastener 83 to pass through the movable hole 222 and be fixedly connected to the moving block 81. Because the multiple synchronous belts 31 are arranged in an upper and lower staggered manner, the multiple adjustment followers 8 and the multiple adjustment blocks 9 are installed above or below the second mounting plate 22 according to the position of the synchronous belts 31.

[0060] A plurality of carrier blocks 4 are respectively arranged at the top ends of a plurality of rotating shafts 3. The carrier blocks 4 are used to adsorb and fix the bottom surface of the product to be inspected, thereby exposing the four side surfaces and the top surface of the product to be inspected. Through the rotation control of the first rotary driver 6 and the second rotary driver 7, all six surfaces can be within the detection range of the visual inspection component, thereby realizing the inspection of the six surfaces of the product to be inspected. At the same time, the top of the carrier block 4 has a suction port for vacuuming to adsorb and fix the product to be inspected. By adsorbing and fixing the product to be inspected, the carrier block 4 can avoid damage to the surface of the product to be inspected, and can also quickly achieve adsorption and release.

[0061] like Figure 4As shown, the positioning plate 5 is mounted on the carrier plate 1 and located to one side of the rotating mounting plate 2. The positioning plate 5 is parallel to the support platform 11. When the first rotary actuator 6 rotates the rotating mounting plate 2 and its components, the positioning plate 5 acts as a positioning mechanism, causing the rotating mounting plate 2 to stop rotating when it contacts the positioning plate 5. At this point, the carrier block 4 is controlled to stop adsorption, and the product to be inspected separates from the carrier block 4 and falls onto the positioning plate 5. The first rotary actuator 6 is then controlled to rotate the rotating mounting plate 2 to its original position, exposing the bottom surface of the product to be inspected for inspection by the visual inspection component.

[0062] In this embodiment, the installation height of the positioning plate 5 allows the first rotary actuator 6 to rotate the rotating mounting plate 2 90 degrees about the first axis, and the positioning plate 5 to position the product to be inspected. This allows the bottom of the product to be turned over for inspection. Furthermore, the rotation angle can be set according to actual needs.

[0063] In this embodiment, the detection platform further includes a first linear drive 20 and a second linear drive 30. Figure 1 and Figure 2 As shown in the figure, a first linear actuator 20 is connected below the carrier plate 1 and is used to drive the carrier plate 1 in a first direction X. A second linear actuator 30 is connected below the first linear actuator 20 and is used to drive the first linear actuator 20 and the carrier plate 1 in a second direction Y. The first direction X and the second direction Y are perpendicular, and the first axial direction is parallel to the second direction Y. The first linear actuator 20 and the second linear actuator 30 are used to move the carrier plate 1 and its components to a designated position to complete product surface inspection.

[0064] The first linear drive 20 and the second linear drive 30 may be linear drive mechanisms such as a linear drive cylinder, a motor, a ball screw, and a slide rail.

[0065] In this embodiment, the detection platform further includes a protective cover connected to the rotating mounting plate 2 and disposed on the outside of the second rotating driver 7 for protection and improving safety.

[0066] An external mechanism places the product to be inspected on the carrier block 4, and the second linear drive 30 moves the rotating mounting plate 2 to the specified position along the Y axis. Then the first linear drive 20 moves the rotating mounting plate 2 to the specified position along the X axis. The second rotary drive 7 drives the two middle rotating shafts 3 to rotate through the synchronous belt 31. The middle rotating shaft 3 rotates synchronously to both ends through the synchronous belt 31, thereby realizing the synchronous rotation of multiple carrier blocks 4, so that the four sides of the product to be inspected can be inspected. The first rotary drive 6 drives the rotating mounting plate 2 to rotate, that is, the rotating shaft 3 flips at a predetermined angle at the same time, and is positioned by the positioning plate 5. The product to be inspected can be turned over and the bottom surface is exposed to be inspected from above.

[0067] The inspection platform in this embodiment makes maximum use of visual inspection components to achieve multi-faceted inspection of multiple products, thereby reducing the number of inspection repetitions, shortening inspection time, and improving work efficiency.

[0068] This embodiment also provides a visual inspection device, comprising the inspection platform of the above embodiment and a visual inspection component. The visual inspection component may be a conventional structure capable of photographing the surface of a product for inspection. The visual inspection component is located on one side of the inspection platform and is configured to photograph the surface of the product to be inspected to obtain an image for inspection.

[0069] This embodiment also provides a visual inspection device that can be used for visual inspection of multiple sides of a product, and can detect 6 sides of a product. The overall structure is small in size and easy to operate, which greatly saves costs and improves work efficiency.

[0070] The foregoing is merely a preferred embodiment of the present application and is not intended to limit the present application. Persons skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application are intended to be within the scope of protection of the present application.
