Abstract
Description
Technical Field
[0001] This application relates to the field of material conveying technology, and in particular to a flipping assembly and conveying device. Background Technology
[0002] With advancements in automated material handling technology, production lines for optical glass products such as clear glass have seen significant efficiency improvements. In these processes, distinguishing the front and back of the product is crucial, directly impacting the quality of subsequent critical processes such as coating and lamination, especially for curved glass.
[0003] In current production lines, due to limitations in the operation methods or equipment operating modes of upstream processes (such as cleaning or preliminary inspection), the orientation of the front and back of glass parts output to the conveyor line is often inconsistent. Furthermore, different types of products typically do not have a uniform orientation. This inconsistency in front and back orientation poses significant challenges to subsequent automated workstations requiring specific orientations, thus hindering production efficiency. Utility Model Content
[0004] Therefore, it is necessary to provide a flipping component and a transport device to address the issue of inconsistent product orientation.
[0005] This application provides a flipping assembly, which includes a support, a first conveying component, a flipping component, and a lifting driver. The first conveying component is located at the top of the support. The flipping component includes a flipping arm, which is rotatably connected to the support about a first axis and is used to pick up a workpiece. The lifting driver is connected to the support to drive the support to move along a lifting direction between a conveying position and a flipping position. In the lifting direction of the support, the first axis is located below the first conveying component. When the support is in the conveying position, the conveying plane of the first conveying component and the conveying plane of the conveying assembly are located at the same position in the lifting direction, and the flipping arm is located below the first conveying component. When the support is in the flipping position, the flipping arm can be rotated so that the part of it used to pick up the workpiece is located at the same position in the lifting direction as the conveying plane of the conveying assembly.
[0006] In one embodiment, the first conveying component includes at least one conveying member rotatably connected to the support about a second axis; the second axis is located above the first axis along the lifting direction.
[0007] In one embodiment, the bracket, the flipping component disposed on the bracket, and the first conveying component constitute a flipping assembly, and the flipping assembly includes a plurality of the flipping assemblies.
[0008] In one embodiment, the lifting driver drives multiple flipping groups to lift and lower synchronously.
[0009] In one embodiment, the plurality of lifting drivers correspond to driving the plurality of flipping groups to lift and lower independently.
[0010] In one embodiment, the flipping components of each of the flipping groups rotate independently.
[0011] In one embodiment, the flipping arm includes an arm body, a stop, and a pickup part. One end of the arm body is rotatably connected to the support, and the pickup part is located on the side of the other end of the arm body. The pickup part has a contact surface for contacting the workpiece. The stop is located on the side of the arm body where the pickup part is located, and is closer to the support than the pickup part. When the support is in the flipping position, the contact surface is parallel or coplanar with the conveying plane of the conveying assembly, and the stop is used to block the workpiece conveyed by the conveying assembly.
[0012] In one embodiment, the tilting arm can rotate around the first axis between a picking position and a discharging position; when the tilting arm is in the picking position, the orthographic projection of the picking part overlaps with the second conveying component, and the contact surface has a first preset distance from the conveying plane of the second conveying component; when the tilting arm is in the discharging position, the orthographic projection of the picking part overlaps with the third conveying component, and the contact surface has a second preset distance from the conveying plane of the third conveying component.
[0013] In one embodiment, the number of the flipping arms is two, the two flipping arms are arranged in parallel, and the two flipping arms are rotationally symmetrical about the first axis.
[0014] In one embodiment, the flipping component further includes a slip ring, which includes a base and a rotating part. The base is connected to the rotating part and is fixed to the bracket. The rotating part is rotatably connected to the base about the first axis, and the flipping arm is connected to the rotating part and rotates about the first axis.
[0015] In one embodiment, the flipping assembly further includes a flipping driver disposed on the bracket and connected to the rotating part.
[0016] In one embodiment, the flipping arm further includes an arm body and a pickup part. One end of the arm body is connected to the rotating part, and the pickup part is located at the other end of the arm body. The arm body has a transmission channel that connects the rotating part and the pickup part.
[0017] This application also provides a transport device, which includes a conveying assembly and a flipping assembly as described above; the conveying assembly includes a second conveying component and a third conveying component, the second conveying component and the third conveying component being spaced apart, and the support being located within the space.
[0018] In the aforementioned flipping assembly, the flipping arm is used to pick up the workpiece, and the flipping arm can rotate around a first axis. Therefore, after the flipping arm picks up the workpiece, it flips it around the first axis to achieve workpiece flipping. Furthermore, the first conveying component is located at the top of the support. In the lifting direction of the support, the first axis is located below the first conveying component. The support moves in the lifting direction between the conveying position and the flipping position. When the support moves to the flipping position, the flipping arm can rotate until its workpiece-picking part is at the same position as the conveying plane of the conveying component in the lifting direction. At this time, the flipping arm can pick up the workpiece conveyed by the conveying component and flip the workpiece. When it is not necessary to flip the workpiece, the support can be moved to the conveying position. At this time, the conveying plane of the first conveying component and the conveying plane of the conveying component are at the same position in the lifting direction, so the first conveying component can cooperate with the conveying component to convey the workpiece. Furthermore, at this time, the flipping arm is located below the first conveying component, so the flipping arm will not interfere with the conveying movement of the workpiece. With this configuration, the flipping assembly is compatible with different environments where workpiece flipping is required and where it is not. In other words, the flipping assembly can switch between unobstructed transport mode and flipping mode according to the specific posture of the workpiece, so as to flexibly adjust the posture of the workpiece, facilitate the subsequent workstation to process the workpiece, and improve production efficiency.

Detailed Implementation
[0027] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.
[0028] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.
[0029] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.
[0030] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0031] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.
[0032] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.
[0033] See Figure 1 , Figure 1This diagram shows an isometric view of a transport device according to an embodiment of the present application. The transport device 10 provided in this embodiment includes a flipping assembly 20 and a conveying assembly 30. The conveying assembly 30 is used to convey a workpiece 50 along the conveying direction S1. The flipping assembly 20 is disposed between two parts of the conveying assembly 30. When the workpiece 50 conveyed by the conveying assembly 30 needs to be flipped, the flipping assembly 20 can flip the workpiece 50 and transfer the workpiece 50 from one part of the conveying assembly 30 to the other part. When the workpiece 50 conveyed by the conveying assembly 30 does not need to be flipped, the flipping assembly 20 can retract relative to the conveying assembly 30 to cooperate with the conveying assembly 30 in transporting the workpiece 50.
[0034] It is understandable that the flipping component 20 typically has the function of blocking and picking up workpieces 50; however, workpieces 50 do not always require flipping. In various embodiments of this application, the flipping component 20 is configured with a lifting and retracting function. When a batch of workpieces 50 does not require flipping, the flipping component 20 can be operated to retract relatively, allowing workpieces 50 to pass unimpeded, thus improving the compatibility of the transport device 10 with different application scenarios. Furthermore, in some embodiments, due to the processing at the upstream station of the transport device 10, workpieces 50 may exhibit inconsistent front and back postures. In this case, the flipping component 20 can flip some workpieces 50 to the same front or back posture as other workpieces 50. For example, when the downstream process of the transport device 10 requires workpieces 50 to maintain a uniform front-facing posture, the flipping component 20 can flip workpieces 50 with a back-facing posture as they pass; while when workpieces 50 with a front-facing posture pass, the flipping component 20 can retract relatively to allow those workpieces 50 to pass unimpeded. This ensures that the workpieces 50 downstream of the transport device 10 have a uniform posture, making them easier to process.
[0035] Please see Figure 1 and Figure 2 In one embodiment, the transport device 10 further includes a transport assembly 30, which includes a second transport component 31 and a third transport component 32. The second transport component 31 and the third transport component 32 are spaced apart, and a flipping assembly 20 is arranged at the interval 33. The flipping assembly 20 flips the workpiece 50 as needed or allows the workpiece 50 to pass through the interval 33 without obstruction.
[0036] Please see Figure 3 and Figure 4 , Figure 3 This paper shows an isometric schematic diagram of a flipping assembly provided in one embodiment of the present application. Figure 4 for Figure 3The image shows a side view of the flipping assembly. An embodiment of this application provides a flipping assembly 20 including a support 100, a first conveying component 200, a flipping component 300, and a lifting driver 400. Both the first conveying component 200 and the flipping component 300 are disposed on the support 100. The lifting driver 400 is connected to the support 100 to drive the support 100 to move along the lifting direction S2 between the conveying position and the flipping position. The first conveying component 200 is disposed at the top of the support 100 and is used to convey the workpiece 50. The flipping component 300 includes a flipping arm 310, which is rotatably connected to the support 100 around a first axis O1 and is used to pick up the workpiece 50. Therefore, the flipping arm 310 can pick up the workpiece 50 and flip it. In the lifting direction S2 of the support 100, the first axis O1 is located below the first conveying component 200. When the support 100 is in the conveying position, the conveying plane PL of the first conveying component 200 and the conveying plane PL of the conveying assembly 30 are located at the same position in the lifting direction S2, and the flipping arm 310 is located below the first conveying component 200. When the support 100 is in the flipping position, the flipping arm 310 can be rotated so that its part for picking up the workpiece 50 is located at the same position in the lifting direction S2 as the conveying plane PL of the conveying assembly 30. Figure 2 The bracket 100 shown is in the conveying position.
[0037] In the aforementioned flipping assembly 20, the flipping arm 310 is used to pick up the workpiece 50, and the flipping arm 310 can rotate around the first axis O1. Therefore, after the flipping arm 310 picks up the workpiece 50, it flips it around the first axis O1, thus achieving the flipping of the workpiece 50. Furthermore, the first conveying component 200 is located at the top of the support 100. In the lifting direction S2 of the support 100, the first axis O1 is located below the first conveying component 200. The support 100 moves along the lifting direction S2 between the conveying position and the flipping position. When the support 100 moves to the flipping position, the flipping arm 310 can rotate until its part for picking up the workpiece 50 is at the same position as the conveying plane PL of the conveying assembly 30 in the lifting direction S2. At this time, the flipping arm 310 can pick up the workpiece 50 conveyed by the conveying assembly 30 and cause the workpiece 50 to flip. When there is no need to flip the workpiece 50, the support 100 can be moved to the conveying position. At this time, the conveying plane PL of the first conveying component 200 and the conveying plane PL of the conveying assembly 30 are located at the same position in the lifting direction S2, so the first conveying component 200 can cooperate with the conveying assembly 30 to convey the workpiece 50. Furthermore, at this time, the flipping arm 310 is located below the first conveying component 200, so the flipping arm 310 will not interfere with the conveying movement of the workpiece 50. With this configuration, the flipping assembly 20 is compatible with different environments, both those requiring and not requiring the flipping of the workpiece 50. In other words, the flipping assembly 20 can switch between unobstructed conveying mode and flipping mode according to the specific posture of the workpiece 50 to flexibly adjust the posture of the workpiece 50, facilitating subsequent processing of the workpiece 50 and improving production efficiency.
[0038] It is understood that the support 100 is located within the interval 33 between the second conveying member 31 and the third conveying member 32.
[0039] In each embodiment, the conveying plane PL of the first conveying component 200 and the conveying plane PL of the conveying assembly 30 are located at the same position in the lifting direction S2. This means that the side of the first conveying component 200 used to contact the workpiece 50 (i.e., the conveying plane PL of the first conveying component 200) is coplanar with the side of the second conveying component 31 and the third conveying component 32 used to contact the workpiece 50 (i.e., their conveying planes PL), or has only a small error. In each embodiment, the tilting arm 310 can be rotated so that the part used to pick up the workpiece 50 is located at the same position in the lifting direction S2 as the conveying plane of the conveying assembly 30. This means that when the tilting arm 310 is in the picking position mentioned below, the side of the tilting arm used to contact and pick up the workpiece 50 (i.e., the contact surface 314 of the picking part 313 mentioned below) is coplanar with the side of the second conveying component 31 and the third conveying component 32 used to contact the workpiece 50 (i.e., their conveying planes PL), or has only a small error.
[0040] It should be noted that since the flipping arm 310 is rotatably connected to the support 100 around the first axis O1, the flipping arm 310 can flip to the position through the conveying plane PL of the conveying assembly 30 even when the support 100 is in the conveying position. In various embodiments of this application, the flipping arm 310 can be configured to be completely below the first conveying component 200 at at least one position during its rotation around the first axis O1. Thus, when the support 100 is in the conveying position, operating the flipping arm 310 to rotate to the aforementioned position completely below the first conveying component 200 can prevent the flipping arm 310 from interfering with the movement of the workpiece 50 to the conveying assembly 30 and the first conveying component 200. Furthermore, it should be emphasized that the flipping arm 310 is capable of flipping; regardless of whether the support 100 is in the conveying position or the flipped position, the flipping arm 310 has the ability to flip to the conveying plane PL through the conveying assembly 30. In this regard, in various embodiments of this application, the bracket 100 can be configured to be in the flipped position, and when the flipping arm 310 is flipped to its picking part (i.e., the contact surface 314 mentioned below) and acts on the workpiece 50, it has a better contact effect and the picking is more stable.
[0041] The embodiments of this application do not limit the conveying method of the first conveying component 200, the second conveying component 31, and the third conveying component 32. The three components can employ conveyor belt conveying, friction wheel conveying, double-speed chain conveying, and roller conveying, among other methods. As one example, when the three components use a conveyor belt, the aforementioned conveying plane PL refers to the top surface of the conveyor belt used to support the workpiece 50. When the three components use friction wheel conveying or roller conveying, the aforementioned conveying plane PL refers to the cross-section (usually the top cross-section) of the friction wheel or roller that contacts the workpiece 50.
[0042] Please see Figure 5 and Figure 6 In one embodiment, the first conveying component 200 includes at least one conveying member 210, which is rotatably connected to the support 100 about a second axis O2. The conveying member 210 is used to contact and transport the workpiece 50. Thus, when the support 100 is in the conveying position, the conveying member 210 allows the workpiece 50 to pass smoothly. Along the lifting direction S2, the second axis O2 is located above the first axis O1. Further, the first axis O1 and the second axis O2 are arranged parallel to each other.
[0043] Furthermore, when there are multiple conveying components 210, the multiple conveying components 210 can be arranged along the conveying direction S1 of the conveying assembly 30 to jointly support the workpiece 50 flowing through the interval 33 between the second conveying component 31 and the third conveying component 32, so that the workpiece 50 is smoothly conveyed from the second conveying component 31 to the third conveying component 32.
[0044] In one embodiment, the first conveying component 200 may have the function of actively conveying the workpiece 50. In this case, the first conveying assembly 30 further includes a drive module (not shown in the figure, the same below), which is connected to the conveying component 210 to actively transport the workpiece 50. Of course, in other embodiments, the first conveying component 200 may also be configured to passively allow the workpiece 50 to pass through, thereby simplifying the structure of the first conveying component 200, facilitating its installation on the bracket 100, and facilitating its arrangement between the second conveying component 31 and the third conveying component 32.
[0045] In one embodiment, the conveyor 210 may be configured as a wheel-like structure or a roller-like structure.
[0046] like Figure 1 As shown, the conveying assembly 30 may have multiple conveying channels 34 to improve conveying efficiency. See also... Figure 5 and Figure 6 Combined Figure 3 In one embodiment, the support 100, the flipping component 300 disposed on the support 100, and the first conveying component 200 constitute a flipping group 21. The flipping assembly 20 includes multiple flipping groups 21, which correspond to multiple conveying channels 34 respectively, so as to flip the workpiece 50 in each conveying channel 34.
[0047] In one embodiment, when the workpieces 50 transported by the transport device 10 have a uniform posture and need to be flipped uniformly, a lifting driver 400 can be configured to drive multiple flipping groups 21 to lift synchronously.
[0048] Please see Figure 3 and Figure 4 In one embodiment, the transport device 10 further includes a base frame 40, and the conveying assembly 30 is disposed on the base frame 40. The flipping assembly 20 includes a connecting frame 500 and a carrier plate 600. The connecting frame 500 is connected to the base frame 40, and the carrier plate 600 is movably disposed on the connecting frame 500. Multiple flipping groups 21 are disposed on the carrier plate 600, and a lifting drive 400 is connected to the carrier plate 600. By driving the carrier plate 600 to move, the multiple flipping groups 21 move synchronously along the lifting direction S2.
[0049] Furthermore, the flipping assembly 21 may be connected to the support 100 and the carrier plate 600, so that each flipping assembly 21 moves synchronously with the carrier plate 600 along the lifting direction S2.
[0050] In another embodiment, multiple lifting drivers 400 can be configured to drive multiple flipping groups 21 to lift independently, in order to address situations where the workpieces 50 transported by the transport device 10 have inconsistent postures.
[0051] It is easy to understand that the workpieces 50 in each conveying channel 34 of the conveying assembly 30 do not always move synchronously. Therefore, in one embodiment, the flipping component 300 of each flipping group 21 can be configured to rotate independently to flip the workpieces 50 conveyed in each conveying channel 34 independently.
[0052] Please see Figure 6 In one embodiment, there are two flipping arms 310, which are rotationally symmetrical about a first axis O1. That is, during the rotation of each flipping arm 310 around the first axis O1, each flipping arm 310 can rotate to the same position relative to the conveying component 30, facilitating the picking up of the workpiece 50 and flipping it over in the same posture and manner. Furthermore, the two flipping arms 310 are arranged in parallel. It is easy to understand that the support 100 is located within the interval 33 between the second conveying component 31 and the third conveying component 32, that is, the second conveying component 31 and the third conveying component 32 are located on different sides of the support 100. Therefore, by configuring the two flipping arms 310 to be arranged in parallel, during rotation, when one flipping arm 310 is aligned with the second conveying component 31, the other flipping arm 310 can be aligned with the third conveying component 32. The alternating switching of the positions of the two flipping arms 310 can improve the efficiency of flipping the workpiece 50. Furthermore, the two parallel flipping arms 310 can be conveniently positioned simultaneously below the conveying plane PL of the conveying assembly 30 to avoid the conveying plane PL. In other words, the parallel arrangement of the two flipping arms 310 in this application can balance the avoidance effect of the flipping arms 310 relative to the conveying plane PL with the efficiency of flipping the workpiece 50 conveyed by the conveying assembly 30.
[0053] Please see Figure 5 and Figure 6In one embodiment, the flipping arm 310 includes an arm body 311, a stop 312, and a pickup part 313. One end of the arm body 311 is rotatably connected to the support 100, and the pickup part 313 is located on the side of the other end of the arm body 311. The stop 312 is located on the side of the arm body 311 where the pickup part 313 is located, and is closer to the support 100 than the pickup part 313. When the support 100 is in the flipped position, the contact surface 314 is parallel or coplanar with the conveying plane PL of the conveying assembly 30, so as to fully contact and pick up the workpiece 50 conveyed by the conveying assembly 30. And when the support 100 is in the flipped position, the stop 312 is used to block the workpiece 50 conveyed by the conveying assembly 30, so that the workpiece 50 stops, so that the pickup part 313 can stably pick up the workpiece 50. It is easy to understand that the end of the arm body 311 can be rotatably connected to the support 100 about a first axis O1.
[0054] In another embodiment, a sensor can be configured to sense the position of the workpiece 50 at the flipping assembly 20, and the sensor can be configured to control the start and stop of the conveying assembly 30. Thus, when the workpiece 50 is transported to the flipping assembly 20 by the conveying assembly 30, the sensor is triggered to stop the conveying assembly 30, so that the flipping arm 310 can stably pick up the workpiece 50.
[0055] Please see Figure 5 and Figure 6 In one embodiment, the picking unit 313 has a contact surface 314 that contacts the workpiece 50, and the flipping arm 310 can rotate around the first axis O1 between a picking position and a discharging position. When the flipping arm 310 is in the picking position, the orthographic projection of the picking unit 313 overlaps with the second conveying member 31, so the flipping arm 310 can pick up the workpiece 50 conveyed by the second conveying member 31. Furthermore, when the flipping arm 310 is in the picking position, the contact surface 314 has a first preset distance from the conveying plane PL of the second conveying member 31. When the flipping arm 310 is in the discharging position, the orthographic projection of the picking unit 313 overlaps with the third conveying member 32, and the contact surface 314 has a preset distance from the conveying plane PL of the third conveying member 32. Thus, the workpiece 50 can be flipped stably and transferred from the second conveying member 31 to the third conveying member 32.
[0056] It is understood that the first and second preset distances can be specifically designed based on the orientation of the pickup unit 313 relative to the workpiece 50 when picking it up, and the thickness of the workpiece 50 on the vertical conveying plane PL. The pickup unit 313 can operate on one side of the workpiece 50 that contacts the conveying plane PL, and it can also operate on the side of the workpiece 50 that faces away from the conveying plane PL. Please refer to [link / reference]. Figure 6As one example, when the tilting arm 310 is in the picking position, the picking part 313 of the tilting arm 310 acts on the side of the workpiece 50 that contacts the second conveying component 31 (i.e., below the workpiece 50). At this time, the first preset distance is zero, and the contact surface 314 is parallel to the conveying plane PL of the second conveying component 31. When the tilting arm 310 is tilted to the unloading position, the picking part 313 is located on the side of the workpiece 50 away from the conveying plane PL. The second preset distance can be equal to the thickness of the workpiece 50, so as to smoothly place the workpiece 50 onto the third conveying component 32.
[0057] Similarly, when the tilting arm 310 is in the picking position, the picking part 313 of the tilting arm 310 acts on the side of the workpiece 50 away from the second conveying component 31 (i.e., above the workpiece 50), and the first preset distance can be equal to the thickness of the workpiece 50. When the tilting arm 310 is tilted to the unloading position, the picking part 313 acts on the side of the workpiece 50 that is used to contact the third conveying component 32, the contact surface 314 is coplanar with the conveying plane PL, and the second preset distance is zero.
[0058] In other words, of the first preset distance and the second preset distance, one is zero, and the other is equal to the thickness of the workpiece 50 in the direction of the vertical conveying plane PL. The direction of the aforementioned vertical conveying plane PL can be the lifting direction S2.
[0059] Please see Figure 6 In one embodiment, when the tilting arm 310 is in the material-picking position, the tilting arm 310 is completely below the first conveying member 200 in the lifting direction S2. Of course, in other embodiments, the tilting arm 310 can also be configured to have a dedicated clearance position, in which the tilting arm 310 is completely below the first conveying member 200 in the lifting direction S2 when it is in the clearance position.
[0060] Please continue reading. Figure 6 In one embodiment, the arm body 311 is eccentrically arranged relative to the first axis O1, and the picking part 313 is located on the side of the arm body 311 closer to the first axis O1. With this arrangement, the contact surface 314 can be positioned close to the conveying plane PL before and after flipping, which facilitates stable transfer of the workpiece 50.
[0061] Please see Figure 7 Combined Figure 5In one embodiment, the pickup unit 313 can be configured to pick up the workpiece 50 by negative pressure adsorption. The flipping component 300 also includes a slip ring 320, which is disposed on the support 100 and connected to the flipping arm 310 to drive the flipping arm 310 to rotate around the first axis O1. The slip ring 320 is used to communicate with a negative pressure generator (not shown, the same below) and is also connected to the pickup unit 313 to apply negative pressure adsorption to the workpiece 50 through the pickup unit 313. It is understood that the slip ring 320 can stably transfer the fluid medium between the relatively fixed negative pressure generator and the relatively rotating flipping arm 310, so as to form negative pressure at the pickup unit 313 of the flipping arm 310 and reduce the risk of entanglement of the corresponding transmission pipe.
[0062] Furthermore, the slip ring 320 includes a base 321 and a rotating part 322. The base 321 is fixed to the bracket 100 and is used to connect to the negative pressure generator. The rotating part 322 is rotatable relative to the base 321, and the base 321 and the rotating part 322 are in communication. It can be understood that the slip ring 320 is configured to stably transfer fluid medium between the relatively rotating base 321 and the rotating part 322. The rotating part 322 is rotatably connected to the base 321 about a first axis O1, and the tilting arm 310 is connected to the rotating part 322 and rotates about the first axis O1. With this configuration, the rotating part 322 and the tilting arm 310 rotate synchronously, and the fluid medium transfer pipe can be connected between the rotating part 322 and the tilting arm 310. Since they rotate synchronously, the fluid medium transfer pipe is less likely to become entangled and hinder rotation.
[0063] In one embodiment, one end of the arm body 311 is connected to the rotating part 322, meaning the arm body 311 is rotatably connected to the support 100 via the rotating part 322, and the pickup part 313 is located at the other end of the arm body 311. The arm body 311 has a transmission channel (not shown in the figure, the same below) for transmitting fluid media, and the transmission channel connects the rotating part 322 and the pickup part 313. In other words, in this embodiment, the arm body 311 can be directly connected to the rotating part 322.
[0064] Please see Figure 7 Combined Figure 5 In one embodiment, the flipping assembly 20 further includes a flipping driver 700, which is disposed on the bracket 100 and connected to the flipping arm 310 to drive the flipping arm 310 to rotate about the first axis O1. The flipping driver 700 can be connected to the rotating part 322 to drive the flipping arm 310 to flip through the rotating part 322.
[0065] Furthermore, the flipping driver 700 can be directly connected to the rotating part 322 to drive the rotating part 322 and the flipping arm 310 to rotate. Alternatively, in another embodiment, the flipping assembly 20 further includes a transmission component 800, through which the flipping driver 700 is connected to the rotating part 322. This arrangement improves the flexibility of the placement of the flipping driver 700, reserving space along the axial direction of the first axis O1 to facilitate the sequential arrangement of multiple flipping groups 21 along the axial direction of the first axis O1. It is understood that the first axis O1 can be perpendicular to the conveying direction S1 of the conveying assembly 30. The multiple conveying channels 34 and the multiple flipping groups 21 of the conveying assembly 30 are arranged along the axial direction of the first axis O1.
[0066] Please continue reading. Figure 7 Combined Figure 5 In one embodiment, the transmission component 800 can be configured to drive the flip driver 700 and the rotating part 322 via a belt drive. The transmission component 800 includes a transmission belt 810, a first wheel 820, and a second wheel 830. The transmission belt 810 is wrapped around the first wheel 820 and the second wheel 830 so that when one of them rotates, the other rotates. The flip driver 700 can be connected to the first wheel 820, and the rotating part 322 can be connected to the second wheel 830. The flip driver 700 drives the first wheel 820 to rotate, and the first wheel 820 drives the second wheel 830 and the rotating part 322 to rotate via the transmission belt 810. Of course, the transmission component 800 can also be configured to use other transmission methods, which will not be described in detail here.
[0067] Furthermore, the rotating part 322 includes a connecting body 322a and a shaft 322b. The connecting body 322a is rotatably connected to the base 321, and the shaft 322b is connected to the side of the connecting body 322a away from the base 321. The shaft 322b passes through the bracket 100, and the connecting body 322a and the second wheel 830 are located on opposite sides of the bracket 100. The bracket 100 supports the shaft 322b, enabling the second wheel 830 to stably drive the rotating part 322 to rotate. Furthermore, the flipping assembly 20 also includes a bearing 900, which is embedded in the bracket 100. The outer periphery of the bearing 900 is fixedly connected to the bracket 100, and the inner ring of the bearing 900 is connected to the shaft 322b. That is, the shaft 322b is rotatably connected to the bracket 100 through the bearing 900 to improve the smoothness of the rotation of the rotating part 322.
[0068] In one embodiment, any flipping assembly 21 includes a support 100, a first conveying component 200, a flipping component 300, a flipping driver 700, a transmission component 800, and a bearing 900 as described in various embodiments.
[0069] It is understood that the flipping assembly 20 and the transport device 10 provided in the embodiments of this application can be applied to various production and processing equipment with flipping requirements. As one example, the transport device 10 can be applied to an inspection device, which also includes an inspection unit (not shown in the figures, the same below). The transport device 10 is used to transport the workpiece 50 to be inspected to the inspection unit. Since the transport device 10 includes the flipping assembly 20, the transport device 10 can flip the workpiece 50 to be inspected, so that the workpiece 50 at the inspection unit has a uniform posture, ensuring the accuracy and reliability of the inspection.
