Description

Technical Field

[0001] This invention relates to the field of new energy vehicle production technology, and more specifically, to a carton-flipping device and method. Background Technology

[0002] The new energy vehicle manufacturing industry involves multiple links and production lines, including the production, processing, testing, packaging, transportation of various components, and final vehicle assembly. Therefore, in the actual production process, many corresponding components are transported and packaged, as well as undergo corresponding testing. For example, after the production of major components is completed, they are temporarily stored in cardboard boxes. After corresponding testing and labeling, they are transported to the assembly line. In some production lines, before the corresponding new energy vehicle component packaging boxes are opened, the boxes also need to be inspected and marked.

[0003] After being packaged in cardboard boxes, the new energy vehicle components are transported to their respective locations or other workshops and production lines via corresponding conveyor lines. The conveyor lines mainly consist of conveying mechanisms (such as conveyor belts, conveyor rollers, and conveyor chains, which are common industrial conveying equipment) and related testing and operation equipment. The component boxes are continuously conveyed on the conveyor mechanism, passing through the corresponding workstations. For example, during the conveying process, visual recognition equipment is used to inspect the appearance of the component boxes to prevent damage or dents on the outer surface of the component boxes. After the appearance inspection of the component boxes is completed, they are then labeled or printed with inspection labels or other relevant information on the outer surface of the qualified component boxes.

[0004] For some new energy vehicle components, which have strict quality requirements, numerous labeling (or printing) locations, and other production requirements that require more work on the surfaces of the component box, it is necessary to flip the component box during the transportation process to expose the bottom surface that was originally in contact with the conveying structure for more thorough related work.

[0005] To quickly flip component boxes, robotic arms or flipping frames need to be installed at appropriate positions on the conveyor mechanism to flip the boxes, clamp them, and then continue conveying. However, for some heavy or delicate new energy vehicle components, such as packaging boxes for new energy battery packs or automotive control components, strict safety measures must be taken during actual flipping to avoid significant impacts and vibrations.

[0006] In existing carton-flipping equipment, if clamping devices are used to flip the component boxes, and the new energy vehicle components inside the boxes are relatively heavy, a greater clamping force is required to hold the boxes in place to prevent them from loosening and falling. However, this can easily cause crush damage to the side walls of the boxes. This can lead to identification errors when the component boxes are subsequently used for inspection and identification. If a flipping frame is used to support the component boxes before flipping them, and the new energy vehicle components inside are relatively heavy (for example, if multiple batteries need to be stored in the component box at the same time), their inertia is also relatively large. When the surface of the component box falls onto the subsequent conveying mechanism during flipping, it can easily create a certain inertial impact. If the impact is large, it will not only affect the safety of the new energy vehicle components inside the box, but also cause crush damage to the box walls, affecting subsequent identification. Summary of the Invention

[0007] The present invention provides a carton flipping device and method to solve the problem that when the weight of new energy vehicle components inside the component box is relatively large, the inertia is also relatively large. When flipping, the surface of the component box is prone to a certain inertial impact when it falls on the subsequent conveying mechanism. If the impact is large, it will not only affect the safety of the new energy vehicle components inside the component box, but also cause certain squeezing damage to the carton wall, affecting subsequent identification.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a carton flipping device, comprising a flipping controller, wherein an input conveying mechanism and an output conveying mechanism are respectively connected to both ends of the flipping controller, the input conveying mechanism and the output conveying mechanism are used to convey the object to be flipped, and multiple sets of unit lifting support roller groups are provided inside the flipping controller, wherein each set of unit lifting support roller groups is arranged parallel to each other;

[0009] The unit lifting support roller assembly includes a lifting roller frame, on which support rollers are rotatably mounted. The lifting roller frame is slidably disposed within the flip controller, and the lifting roller frame is driven to lift by a lifting driver.

[0010] The support roller is used to support the object to be turned. The support roller is equipped with a buffer protection component on its outside. The buffer protection component is used to buffer and protect the object to be turned between the object to be turned and the support roller when the object to be turned is turned.

[0011] In a preferred embodiment, the buffer protection component is a flexible belt, which is sleeved on the outside of each support roller to form a belt conveyor assembly. The support rollers and the flexible belt form contact support. The flip controller is also provided with a tensioning assembly and a belt drive roller group. The tensioning assembly is used to tension the flexible belt, and the belt drive roller group is used to drive the movement of the flexible belt. The flip controller is also provided with a guide roller group for supporting and guiding the flexible belt.

[0012] In a preferred embodiment, the tensioning assembly includes a tensioning frame that is laterally slidably mounted in a flip controller, and an elastic element is installed between the tensioning frame and the flip controller. A tensioning roller is rotatably mounted on the tensioning frame and contacts the flexible belt. The belt drive roller assembly includes a drive roller that is driven to rotate by a rotation drive device and contacts the flexible belt. The tensioning roller, in conjunction with the drive roller of the guide roller assembly and the belt drive roller assembly, causes the flexible belt to form a V-shaped folded area.

[0013] In a preferred embodiment, a plurality of raised strip structures are fixedly connected to the outer surface of the flexible belt. The raised strip structures are integrally formed with the flexible belt, and an edge receiving area is formed between two adjacent raised strip structures.

[0014] In a preferred embodiment, a plurality of air blowing assemblies are provided on one side of the flip controller. Each air blowing assembly includes an air blowing box, and an air blowing hole is provided on one side of the air blowing box corresponding to the support roller. The air blowing box is connected to an air supply system through a pipe.

[0015] In a preferred embodiment, the convex structure is an I-shaped convex rib, with flanges on both sides of the I-shaped convex rib, and an airbag structure is provided in the edge receiving area between two adjacent I-shaped convex ribs, and an inflation / deflation component is provided on the airbag structure.

[0016] In a preferred embodiment, the inflation / deflation assembly includes a one-way air inlet and an exhaust control valve. The air inlet box is fixedly installed on the end of the lifting roller frame, and multiple sets of air inlets are provided on the air inlet box. The air inlet box slides with the edge of the flexible belt. The one-way air inlet is provided at one end of the airbag structure corresponding to the air inlet box. A one-way valve is provided inside the one-way air inlet. One set of air inlets on the air inlet box is provided corresponding to the one-way air inlet.

[0017] In a preferred embodiment, the exhaust control valve is disposed in the flexible belt at a position corresponding to the airbag structure. The exhaust control valve includes a first flexible block and a second flexible block, both of which are flexible structures and embedded in the flexible belt. The areas of the first and second flexible blocks near the airbag structure are set as hollow areas. The outer protrusion and the inner protrusion are respectively fixedly connected to the positions of the first and second flexible blocks away from the airbag structure. When the flexible belt is straight, the outer protrusion and the inner protrusion are tightly attached to each other under the elastic action of the flexible belt. When the flexible belt in the corresponding area forms a bend away from the direction of the exhaust control valve, the first and second flexible blocks are open, and the outer protrusion and the inner protrusion separate.

[0018] In a preferred embodiment, the inside of the flip controller is provided with a vertical lifting guide groove, and a slider structure is fixedly connected to the outside of the lifting roller frame. The slider structure is slidably installed in the lifting guide groove.

[0019] A method for turning over a cardboard box includes the following steps:

[0020] Step 1: The component box is transported to the flipping controller via the input conveyor mechanism and supported by the support rollers in the corresponding area;

[0021] Step 2: Using the flipping interface as the boundary, control the support rollers on the front and back sides of the flipping interface to gradually descend in a direction away from the flipping interface. During the descent, keep the support rollers on both sides of the flipping interface forming corresponding support planes, and ensure that the support planes formed by the support rollers on both sides of the flipping interface are perpendicular to each other, thereby causing the component box to start flipping.

[0022] Step 3: Adjust the lifting height of each support roller to make the two sets of support planes rotate synchronously, thereby causing the component box to continue to rotate.

[0023] Step 4: After the center of gravity of the component box has passed the flipping interface, control all the previously lowered support rollers to rise until the component box has completed a 90° flip, thus completing the flipping operation.

[0024] The beneficial effects of this invention are as follows: By setting multiple sets of unit lifting support rollers to perform wave-like lifting and lowering movements, this invention can control the flipping of the component box at multiple angles. During flipping, the triangular recessed areas formed by the support rollers on both sides of the flipping interface and the corresponding support planes can effectively support the front and bottom surfaces of the component box. With the help of buffer protective components, the component box can be effectively protected throughout the flipping process. There is no impact during the flipping process, and it will not damage the new energy vehicle components inside the component box. Moreover, when the component box is a cardboard box structure, the cardboard surface can be fully and effectively supported during flipping, without causing hard compression. When flipping the component box, it can effectively ensure the safety of the component box and its internal components, further improving the production efficiency of the new energy vehicle production line. In addition, this flipping device can be adapted to different sizes by controlling the lifting and lowering of the corresponding number of support rollers, which greatly improves the practicality of the device, reduces the production cost of new energy vehicle manufacturing to a certain extent, and ensures the production safety of the corresponding production line in the production of new energy vehicles.

[0041] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0042] Refer to the instruction manual appendix Figures 1 to 14 A carton flipping device and method includes a flipping controller 1. The two ends of the flipping controller 1 are respectively connected to an input conveying mechanism 11 and an output conveying mechanism 12. The input conveying mechanism 11 is connected to the production or packaging production line of new energy vehicle components, while the output conveying mechanism 12 is connected to stacking or transportation equipment, or can be directly transported to other production lines for the manufacturing of new energy vehicles. The input conveying mechanism 11 and the output conveying mechanism 12 are used to convey component boxes 4 (component boxes 4 are box structures for packaging and sealing some new energy vehicle components, such as new energy batteries, automotive control components, structural parts, etc.). The input conveying mechanism 11, the flipping controller 1 and the output conveying mechanism 12 form a set of conveying lines. The component boxes 4 are conveyed along the direction from the input conveying mechanism 11 to the output conveying mechanism 12. The flipping controller 1 is provided with multiple sets of unit lifting support roller groups 2, and each set of unit lifting support roller groups 2 is arranged parallel to each other.

[0043] The unit lifting support roller assembly 2 includes a lifting roller frame 21, on which a support roller 22 is rotatably mounted. The lifting roller frame 21 is slidably disposed within the flip controller 1 (for example, a vertical lifting guide groove 13 is provided on the flip controller 1, and a slider structure 211 is provided on the outside of the lifting roller frame 21, so that the slider structure 211 is slidably installed within the lifting guide groove 13). The lifting roller frame 21 is driven to lift by a lifting driver 23. The lifting driver 23 can be a conventional linear drive device such as a cylinder, a motor screw, or a hydraulic cylinder. When the object to be flipped is relatively heavy, a hydraulic cylinder can be used. The pressure cylinder serves as the lifting drive 23, and each lifting roller frame 21 in each unit lifting support roller group 2 can be equipped with two lifting drives 23, and the two lifting drives 23 drive synchronously, thereby improving the lifting control effect of the lifting roller frame 21. The support roller 22 is used to support the object to be flipped (i.e., the component box 4), that is, to support the component box 4. The support roller 22 is provided with a buffer protection 3 on its outside. The buffer protection 3 is used to buffer and protect the component box 4 between the component box 4 and the support roller 22 when the component box 4 is flipped. Therefore, the buffer protection 3 is preferably made of rubber.

[0044] By setting multiple sets of liftable support rollers 22, each unit of lifting support roller group 2 forms a wave-like tumbling control component within the flip controller 1. For details, please refer to the appendix of the instruction manual. Figure 3 When component box 4 is conveyed to the flipping controller 1, the vertical plane corresponding to the front face of component box 4 before flipping (with the conveying forward direction as the front, the front face of component box 4 is the side corresponding to the conveying direction) serves as the flipping interface 42. When it is necessary to control the flipping of component box 4, the corresponding support rollers 22 in the area of ​​component box 4 can be controlled to descend, thereby forming a triangular recessed area in the flipping controller 1 to support component box 4 and cause component box 4 to tilt. That is, when it is necessary to control the component box 4 to start flipping, the flipping interface 42 serves as the boundary (at this time, the flipping interface 42...). Corresponding to the bottom edge of the front face of the component box 4, the support rollers 22 on both sides of the flipping interface 42 are controlled to gradually descend in a direction away from the flipping interface 42. During the descent, the support rollers 22 on both sides of the flipping interface 42 are kept in a corresponding support plane, and the support planes formed by the support rollers 22 on both sides of the flipping interface 42 are set perpendicular to each other, so as to effectively support the front face and bottom face of the component box 4 at the same time. Then, the lifting height of each support roller 22 is slowly adjusted to make the component box 4 continue to flip. Figure 3 For example, at this time, the center of gravity 41 of component box 4 has not yet crossed the flipping interface 42. The main weight of component box 4 is still borne by the support rollers 22 behind the flipping interface 42. Then, the lifting and lowering of each support roller 22 is controlled so that the support planes formed by the support rollers 22 on both sides of the flipping interface 42 flip. Refer to the appendix of the instruction manual. Figure 4Until the center of gravity zone 41 of component box 4 crosses the flipping interface 42, the main weight of component box 4 is borne by the sets of support rollers 22 on the front side of the flipping interface 42. That is to say, component box 4 will no longer flip backward. At this time, all the previously descending support rollers 22 can be controlled to start gradually rising. During the rising process, it is necessary to keep the sets of support rollers 22 on the front side of the flipping interface 42 in the same support plane. That is, all the support rollers 22 in this area simultaneously provide effective support to the original front face of component box 4 (which will become the bottom face later) until component box 4 completes a 90° flip, thus completing the flipping operation.

[0045] In this configuration, each set of support rollers 22 can be driven without power. Simply tilting the entire flip controller 1 and allowing the component box 4 to slide automatically under gravity will enable the flip controller 1 to transport the component box 4. In addition, each set of support rollers 22 can also be driven independently, meaning that each support roller 22 has rotational power to actively transport the component box 4. The buffer protection component 3 can be a simple soft sleeve 31, that is, a soft sleeve 31 made of rubber, which is placed over the support rollers 22 to provide a certain amount of buffer protection when in contact with the component box 4.

[0046] It should be noted that by setting the number of unit lifting support roller groups 2 and the length of the working area, the component box 4 can be continuously controlled to rotate at 90°, 180°, 270°, and 360°, thus enabling more angles of rotation control for the component box 4. During the control process, the up-and-down movement of each support roller 22 is similar to a wave state. Therefore, the mechanism composed of each group of unit lifting support roller groups 2 is called a wave-type tumbling control assembly. Moreover, depending on the size of different component boxes 4, only the corresponding number of support rollers 22 need to be controlled to rise and fall during actual use to adapt to the size, thus adapting to more sizes of component boxes 4. At the same time, when the component box 4 is rotated, the triangular recessed areas formed by the support rollers 22 on both sides of the rotation interface 42 and the corresponding support planes can effectively support the front and bottom surfaces of the component box 4, and effectively isolate and protect it with the help of the buffer protective parts 3. The component box 4 can be effectively protected throughout the entire rotation process. The device operates without impact, preventing damage to the new energy vehicle components inside component box 4. Furthermore, when component box 4 is constructed as a cardboard box, the cardboard surface is effectively supported during flipping, preventing hard compression and thus avoiding damage to the component box 4 itself. This ensures the safety of component box 4 and its internal new energy vehicle components during flipping operations, especially when the component box 4 contains new energy batteries and other precision components of new energy vehicles, providing effective safety protection for these components. Moreover, the flipping device provided in this embodiment is not limited to paper packaging boxes; it can also flip other types of packaging boxes such as plastic boxes, foam boxes, and wooden boxes. It can adapt to component boxes 4 of various sizes and specifications, fully accommodating the production and manufacturing of different new energy vehicle components. It eliminates the need for separate flipping structures for different component box sizes, effectively saving on new energy vehicle production costs and improving flipping efficiency.

[0047] In the above technical solution, if more efficient conveying is required for each component box 4, each support roller 22 needs to be driven to rotate independently. Moreover, although multiple sets of support rollers 22 support the component box 4 simultaneously, the support area of ​​the roller-type structure is limited. Therefore, there is still room for improvement in the support effect. To this end, this embodiment also provides the following technical solution: the buffer protective component 3 adopts a flexible belt 32. Specifically, the flexible belt 32 is sleeved on the outside of each support roller 22 to form a belt conveyor assembly. The support roller 22 and the flexible belt 32 form contact support. At the same time, in order to adapt to the change of the flexible belt 32 when the above-mentioned unit lifting support roller group 2 forms a triangular concave area, the flip controller 1 is also provided with a tensioning component 5 and a belt drive roller group 6. The tensioning component 5 is used to tension the flexible belt 32 to ensure that the flexible belt 32 will not wrinkle during use. The belt drive roller group 6 is used to tension the flexible belt 32. For motion driving, specifically, the flip controller 1 is also equipped with a guide roller group for supporting and guiding the flexible belt 32. The tensioning assembly 5 includes a tensioning frame 51, which is laterally slidably installed in the flip controller 1, and an elastic element is installed between the tensioning frame 51 and the flip controller 1. A tensioning roller 52 is rotatably installed on the tensioning frame 51, and the tensioning roller 52 contacts and cooperates with the flexible belt 32. The belt drive roller group 6 includes a drive roller, which is driven to rotate by a rotation drive device (e.g., a motor). The drive roller contacts and cooperates with the flexible belt 32. The tensioning roller 52, together with the guide roller group and the drive roller of the belt drive roller group 6, makes the flexible belt 32 form a V-shaped folded area. When the flexible belt 32 is concave in the triangular concave area, the flexible belt 32 in the V-shaped folded area will squeeze the tensioning roller 52 to make it move and shorten the range of the V-shaped folded area to compensate for the concavity of the flexible belt 32 in the triangular concave area.

[0048] By adopting the above-described implementation method, when the component box 4 is flipped, the flexible belt 32 provides buffer support. At the same time, the flexible belt 32 can provide a larger contact support area, thereby improving the protection effect of the component box 4. After the flipping is completed, the flexible belt 32 is driven by the belt drive roller group 6 to drive the component box 4 to continue moving forward. There is no need to drive and control each support roller 22, reducing the drive source, improving the conveying effect and reducing the cost of the device.

[0049] It should be noted that the above solution is not limited to the flipping control of component box 4, but is also applicable to some non-boxed panel component packages 8, such as the stacked and bundled packages used for some interior panels and component shells in new energy vehicles. The solution provided in this embodiment can also effectively flip them. Moreover, since the front end of the panel component package 8 can be effectively supported during the flipping process, the relative slippage between layers of panels caused by gravity when tilted can be effectively avoided, thereby effectively ensuring the safety of the object to be flipped during the flipping process.

[0050] Furthermore, in the above embodiment, due to the addition of the flexible belt 32, the flexible belt 32 actually creates a right-angle bend in the triangular recess area to provide two support planes. The corner of the two support planes is in contact with the bottom edge of the component box 4. As a flexible structure, the flexible belt 32 is mainly in an arc-shaped deformation at this point. If the bottom edge of the component box 4 is required to be relatively sharp, the flexible belt 32 at the arc-shaped point can easily cause the bottom edge of the component box 4 to be squeezed and crushed, thus easily damaging the edge. Therefore, this embodiment also provides the following technical solution: Specifically, multiple protruding strip structures 33 are fixedly connected to the outer surface of the flexible belt 32. The protruding strip structures 33 are integrally formed with the flexible belt 32, and an edge receiving area is formed between two adjacent protruding strip structures 33. For details, please refer to the appendix of the specification. Figure 10 In actual use, before flipping, the edge of the control component box 4 is located in the area between two adjacent convex structures 33 (rounded corners can be set on the convex structure 33. If the edge of the component box 4 is not placed in the receiving area, the rounded corners can be used to guide it during the bending process of the flexible belt 32, and the component box 4 will slide appropriately so that the edge is placed in the receiving area). This makes the bottom edge of the component box 4 suspended and not squeezed.

[0051] Furthermore, when using cardboard boxes as component boxes 4 to package automotive components, paper scraps or paperboard sheets may remain on the production line of new energy vehicle manufacturing. To prevent component boxes 4 from being pressed against paper scraps or paperboard sheets during flipping, affecting visual recognition and detection, or causing reverse compression damage to component boxes 4, this embodiment also provides the following technical solutions, as detailed in the appendix to the specification. Figure 8 On one side of the flip controller 1, there are multiple air blowing components 7. The air blowing components 7 include an air blowing box 71. The air blowing box 71 has an air blowing hole 72 on one side corresponding to the support roller 22. The air blowing box 71 is connected to an air supply system (e.g., an air pump) through a pipe, so that air can be blown on the flexible belt 32 above the flexible belt 32 to clean the flexible belt 32 and avoid the residue of paper scraps and paper boards.

[0052] Based on the above implementation method, tilting may occur during the transportation of component box 4. Please refer to the appendix of the instruction manual. Figure 11 Therefore, within the triangular recessed area, one of the vertical edges of the component box 4 will first contact the support plane formed by the flexible belt 32 on the front side of the flipping interface 42. If the convex structure 33 is too thick and relatively hard, it is easy to damage the vertical edge. Therefore, this embodiment also provides the following technical solution, please refer to the appendix to the specification. Figure 12 and Figure 13 The protruding strip structure 33 can be an I-shaped protruding strip 331. Both sides of the I-shaped protruding strip 331 are provided with flange plates 3311. In actual use, when the flexible belt 32 is in a straight state, the flange plates 3311 can flatten, providing better support for the component box 4. When the flexible belt 32 is bent, the edge can squeeze and deform the flange plates 3311 without damaging the edge of the component box 4. Moreover, through the above arrangement, the main body of the I-shaped protruding strip 331 can be made relatively thin, and it is easy to deform when it comes into contact with the vertical edge of the component box 4.

[0053] In addition, an airbag structure 34 can be provided in the edge receiving area between two adjacent I-shaped protrusions 331, and an inflation and deflation component is provided on the airbag structure 34. When the flexible belt 32 is not bent, air is inflated into the airbag structure 34 to expand it and provide effective support for the component box 4. The support and cushioning effect is better, especially when the component box 4 is tilted, one of the vertical edges is contacted in advance. When the component box 4 needs to be flipped, the flexible belt 32 deflates the airbag structure 34 in the bending area at the corner of the two support planes, so that the airbag structure 34 contracts and thus does not squeeze the bottom edge of the component box 4.

[0054] Furthermore, the aforementioned air-blowing box 71 is fixedly installed on the end of the lifting roller frame 21. Air-blowing components 7 can be installed on all lifting roller frames 21, or they can be installed at intervals of one or two sets. The air-blowing box 71 has multiple sets of air-blowing holes 72. The air-blowing box 71 slides against the edge of the flexible belt 32. The airbag structure 34 has a one-way air inlet 35 corresponding to one end of the air-blowing box 71. A one-way valve is installed inside the one-way air inlet 35. One set of air-blowing holes 72 on the air-blowing box 71 corresponds to one set of one-way air inlets 35. That is, when the flexible belt 32 is in a straight state, and the movement of the flexible belt 32 causes the one-way air inlet 35 to correspond to one of the air-blowing holes 72, refer to the appendix of the instruction manual. Figure 12 and Figure 14 The air inlet 72 can inflate the airbag structure 34 with air.

[0055] Furthermore, an exhaust control valve 36 is provided in the flexible belt 32 at the position corresponding to the airbag structure 34. The exhaust control valve 36 includes a first flexible block 361 and a second flexible block 362. Both the first flexible block 361 and the second flexible block 362 are flexible structures (e.g., rubber) and are embedded in the flexible belt 32. The areas of the first flexible block 361 and the second flexible block 362 near the airbag structure 34 are set as hollow areas. The outer protrusion 363 and the inner protrusion 364 are respectively fixedly connected to the positions of the first flexible block 361 and the second flexible block 362 away from the airbag structure 34. (Refer to the appendix of the specification.) Figure 12 When the flexible belt 32 is straight and not bent, the outer protrusion 363 and the inner protrusion 364 are tightly pressed together by the elasticity of the flexible belt 32, forming a seal in the hollow area. When the component box 4 needs to be flipped, and the flexible belt 32 in the corresponding area bends away from the direction of the exhaust control valve 36, the first flexible block 361 and the second flexible block 362 open up, and the outer protrusion 363 and the inner protrusion 364 separate. The hollow area is opened, and the airbag structure 34 can be automatically deflated without the need for complex pipelines, resulting in relatively low cost.

[0056] Refer to the instruction manual appendix Figure 15 The present invention also provides a method for turning over a cardboard box, comprising the following steps:

[0057] Step 1: The component box 4 is conveyed to the flip controller 1 via the input conveying mechanism 11 and supported by the support roller 22 of the corresponding area;

[0058] Step 2: Using the flipping interface 42 as the boundary, control the support rollers 22 on the front and rear sides of the flipping interface 42 to gradually descend in a direction away from the flipping interface 42. During the descent, keep the support rollers 22 on both sides of the flipping interface 42 forming corresponding support planes, and the support planes formed by the support rollers 22 on both sides of the flipping interface 42 are perpendicular to each other, thereby causing the component box 4 to start flipping.

[0059] Step 3: Adjust the lifting height of each support roller 22 to make the two sets of support planes rotate synchronously, thereby causing the component box 4 to continue to rotate.

[0060] Step 4: After the center of gravity 41 of the component box 4 passes the flipping interface 42, control all the previously descending support rollers 22 to rise until the component box 4 completes a 90° flip, thus completing the flipping operation.

[0061] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
