Description

Technical Field

[0001] This utility model relates to the field of mechanical tooling technology, and in particular to a flipping device and conveying equipment. Background Technology

[0002] With the development of industry, the automation level of production equipment is getting higher and higher. Turning machines are used to flip workpieces, such as steel coils, molds, plates and cabinets.

[0003] In existing technology, a workpiece flipping machine includes a rotating shaft, a fixture, and a motor. The fixture is connected to the rotating shaft, and the motor drive is connected to the rotating shaft. The motor drives the rotating shaft to rotate, thereby causing the fixture to rotate, so as to achieve the flipping of the workpiece. However, when the workpiece to be flipped is a heavy workpiece, the motor needs to overcome a huge starting torque, which is laborious and energy-intensive during rotation. Furthermore, since the distance between the fixture and the ground is fixed, asymmetrical workpieces are affected by mechanical interference during flipping and cannot maintain their original position trajectory. That is, the position of the workpiece before and after flipping is inconsistent, and it is impossible to achieve flipping in the original position. In precision assembly lines, additional positioning and correction fixtures are required, which reduces production efficiency. Utility Model Content

[0004] To address the shortcomings of the prior art, this utility model provides a flipping device and a conveying equipment. When the first driving component drives the flipping frame to rotate, it can save more effort and reduce energy consumption. Furthermore, since the flipping frame can be raised and lowered in the vertical direction, the distance between the flipping frame and the ground is not fixed, thereby enabling the workpiece to be flipped in its original position.

[0005] The technical effects to be achieved by this utility model are realized through the following aspects:

[0006] In a first aspect, this utility model provides a flipping device, comprising:

[0007] The lifting mechanism is set to move vertically; and

[0008] A flipping mechanism is rotatably connected to the lifting mechanism. The flipping mechanism includes a rotating shaft, a flipping component, and a first drive component. The first end of the rotating shaft is rotatably connected to the lifting mechanism.

[0009] The flipping assembly includes a flipping frame and an arc-shaped rack; the flipping frame is connected to the second end of the rotating shaft, the arc-shaped rack is connected to the flipping frame, and the center of the arc of the arc-shaped rack is located at the rotating shaft; the first driving assembly is connected to the arc-shaped rack, thereby driving the flipping frame to flip.

[0010] In some implementations, the radius of the arc center is greater than or equal to half the height of the tilting frame.

[0011] In this implementation, the distance between the arc-shaped rack and the rotating shaft is greater than or equal to half the height of the tilting frame, which makes it easier for the first drive assembly to drive the arc-shaped rack to rotate, thereby ensuring that the tilting frame can tilt.

[0012] In some implementations, the first drive assembly includes a first drive member and a gear, the gear being sleeved on the output end of the first drive member and meshing with the arc-shaped rack.

[0013] In this implementation, the first driving component drives the gear to rotate, and the rotation of the gear drives the arc-shaped rack to rotate, thereby enabling the tilting frame to tilt.

[0014] In some implementations, the lifting mechanism includes a fixed base and a lifting frame, the lifting frame being slidably connected to the fixed base in a vertical direction, the first end of the rotating shaft being rotatably connected to the top of the lifting frame, and the first drive assembly being connected to the side of the lifting frame.

[0015] In this implementation, when the lifting frame rises vertically, it drives the tilting frame and the first drive assembly to rise. When the lifting frame descends vertically, it drives the tilting frame and the first drive assembly to descend, so that the gear of the first drive assembly continuously meshes with the arc-shaped rack, thereby ensuring the reliability of driving the tilting frame to tilt.

[0016] In some implementations, the fixed base has a sliding channel, and the lifting frame has a slider that cooperates with the sliding channel, with the slider slidably disposed within the sliding channel.

[0017] In some implementations, the fixed base is further provided with a limiting groove communicating with the sliding channel, and the first drive component is provided with a limiting plate, which passes through the limiting groove and is connected to the lifting frame.

[0018] In this implementation, when the limiting plate abuts against the top wall of the limiting slide groove, the lifting frame stops rising, and the first driving component drives the arc-shaped rack, thereby driving the tilting frame to tilt; the lifting frame descends until the limiting plate abuts against the bottom wall of the limiting slide groove, at which point the lifting frame stops descending.

[0019] In some implementations, the lifting mechanism further includes a second drive assembly, which is driven and connected to the lifting frame.

[0020] In some implementations, the second drive assembly includes a drive cylinder having a piston rod, the output end of which is connected to the lifting frame.

[0021] Secondly, this utility model provides a conveying device, including a roller conveyor and the aforementioned turning device, wherein the roller conveyor is located below the turning frame.

[0022] In this implementation, after the lifting frame drives the tilting frame to descend to the preset position, the roller conveyor is started. During the rolling process, the roller conveyor carries the tilted workpiece out of the tilting frame, thereby transporting the tilted workpiece to the next station, ensuring the compactness of the overall structure and saving the space occupied by the overall equipment.

[0023] In some implementations, the roller line includes a plurality of rollers arranged in an array.

[0024] In summary, this utility model has at least the following advantages:

[0025] The flipping device provided by this utility model has a lifting mechanism that is movably arranged in the vertical direction. A flipping frame is rotatably connected to the lifting mechanism via a rotating shaft. An arc-shaped rack is connected to the flipping frame, with the center of the arc aligned with the axis of the rotating shaft. A first drive assembly drives the arc-shaped rack to rotate, thereby rotating the flipping frame and causing it to flip. Thus, the first drive assembly can drive the flipping frame to rotate with less effort, reducing energy consumption. Furthermore, because the flipping frame can be raised and lowered vertically, the distance between the flipping frame and the ground is not fixed, allowing the workpiece to flip within its original position.

[0036] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are some, but not all, of the embodiments of this utility model.

[0037] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0038] Example 1:

[0039] Please see the appendix Figure 1 ~Appendix Figure 3 The flipping device 10 of this utility model includes a lifting mechanism 100 and a flipping mechanism 200.

[0040] In this regard, please combine Figure 1 and Figure 2 , Figure 1 The structural relationship between the lifting mechanism 100 and the tilting mechanism 200 in this embodiment of the present invention is illustrated. Figure 2 The diagram illustrates the structural relationship between the tilting frame 221, the arc-shaped rack 222, and the first drive assembly 230 in this embodiment of the present invention. Specifically, the lifting mechanism 100 is movably arranged in the vertical direction; the tilting mechanism 200 is rotatably connected to the lifting mechanism 100, and the tilting mechanism 200 includes a rotating shaft 210, a tilting assembly 220, and a first drive assembly 230, with the first end of the rotating shaft 210 rotatably connected to the lifting mechanism 100. The tilting assembly 220 includes the tilting frame 221 and the arc-shaped rack 222; the tilting frame 221 is connected to the second end of the rotating shaft 210, and the arc-shaped rack 222 is connected to the tilting frame 221, with the center of the arc of the arc-shaped rack 222 located at the rotating shaft 210; the first drive assembly 230 is driven and connected to the arc-shaped rack 222, thereby driving the tilting frame 221 to tilt.

[0041] In this embodiment, the first end of the rotating shaft 210 is rotatably connected to the lifting mechanism 100, and the flipping mechanism 200 is connected to the second end of the rotating shaft 210, so that the flipping mechanism 200 can flip relative to the lifting mechanism 100. Specifically, the arc-shaped rack 222 is disposed on the side of the flipping frame 221 near the lifting mechanism 100, and the center of the arc of the arc-shaped rack 222 is located at the rotating shaft 210. The first driving component 230 drives the arc-shaped rack 222 to rotate along the rotating shaft 210, thereby enabling the flipping frame 221 to flip.

[0042] During the workpiece flipping process, the workpiece to be flipped is first placed in the flipping frame 221 by external equipment. Then, the lifting mechanism 100 rises vertically so that the distance between the flipping frame 221 and the ground is greater than the length of the workpiece to be flipped. Next, the first drive component 230 drives the arc rack 222 to rotate along the rotating shaft 210, thereby causing the flipping frame 221 to flip, thus realizing the flipping of the workpiece to be flipped. Finally, the lifting mechanism 100 descends vertically so that the flipping frame 221 is reset, and the external equipment transports the flipped workpiece to the next work station.

[0043] It is understandable that, since the rack is arc-shaped and the center of the arc of the rack 222 is located at the pivot 210, that is, the center of the arc of the rack 222 is aligned with the pivot of the pivot 210, the first drive assembly 230 drives the tilting frame 221 to tilt more effortlessly. Compared with the prior art, which uses a drive component to directly drive the pivot 210 to make the tilting mechanism 200 tilt, the tilting device 10 of this embodiment has a smaller starting torque of the first drive assembly 230, which is less effortless and consumes less energy when rotating.

[0044] In the aforementioned flipping device 10, the lifting mechanism 100 is vertically movable. The flipping frame 221 is rotatably connected to the lifting mechanism 100 via a rotating shaft 210. An arc-shaped rack 222 is connected to the flipping frame 221, with the arc center of the rack 222 aligned with the axis of the rotating shaft 210. The first drive assembly 230 drives the arc-shaped rack 222 to rotate, thereby causing the flipping frame 221 to rotate and thus flipping the frame 221. In this way, the first drive assembly 230 can drive the flipping frame 221 to rotate with less effort, thus reducing energy consumption. Furthermore, since the flipping frame 221 can be raised and lowered vertically, the distance between the flipping frame 221 and the ground is not fixed, allowing the workpiece to be flipped in its original position.

[0045] In some preferred embodiments, the radius of the arc center is greater than or equal to half the height of the tilting frame 221. That is, the distance between the arc-shaped rack 222 and the rotating shaft 210 is greater than or equal to half the height of the tilting frame 221. This makes it easier for the first drive assembly 230 to drive the arc-shaped rack 222 to rotate, thereby ensuring that the tilting frame 221 can be tilted.

[0046] In some preferred embodiments, please refer to Figure 3 , Figure 3 The diagram illustrates the structural relationship between the first driving member 231 and the gear 232 in this embodiment of the invention. Specifically, the first driving assembly 230 includes the first driving member 231 and the gear 232. The gear 232 is sleeved on the output end of the first driving member 231 and meshes with the arc-shaped rack 222. The first driving member 231 drives the gear 232 to rotate, and the rotation of the gear 232 drives the arc-shaped rack 222 to rotate, thereby enabling the tilting frame 221 to tilt. The structure of the gear 232 meshing with the arc-shaped rack 222 makes it easier to drive the tilting frame 221 to tilt, reducing the energy consumption of the first driving member 231. Preferably, the first driving member 231 can be a motor.

[0047] Example 2:

[0048] The difference between this embodiment and Embodiment 1 is that this embodiment further optimizes the structure of the flipping device 10 of this utility model. Please refer to the appendix. Figure 2 ~Appendix Figure 3 .

[0049] Please see below. Figure 2 , Figure 2 The diagram illustrates the structural relationship between the fixed base 110 and the lifting frame 120 in this embodiment of the present invention. Specifically, the lifting mechanism 100 includes a fixed base 110 and a lifting frame 120. The lifting frame 120 is slidably connected to the fixed base 110 in the vertical direction. The first end of the rotating shaft 210 is rotatably connected to the top of the lifting frame 120, and the first drive assembly 230 is connected to the side of the lifting frame 120.

[0050] In this embodiment, when the lifting frame 120 rises vertically, it drives the tilting frame 221 and the first drive assembly 230 to rise. When the lifting frame 120 descends vertically, it drives the tilting frame 221 and the first drive assembly 230 to descend, causing the gear 232 of the first drive assembly 230 to continuously mesh with the arc-shaped rack 222, thereby ensuring the reliability of driving the tilting frame 221 to tilt. Furthermore, this also makes the overall structure more compact.

[0051] In some preferred embodiments, please refer to Figure 3 , Figure 3The diagram illustrates the structural relationship between the sliding channel 111 and the slider 121 in this embodiment of the invention. Specifically, the fixed base 110 has a sliding channel 111, and the lifting frame 120 has a slider 121 that cooperates with the sliding channel 111. The slider 121 is slidably disposed within the sliding channel 111. The lifting frame 120 is slidably connected to the sliding channel 111 via the slider 121, thereby making the lifting frame 120 smoother and more stable during the upward or downward sliding process. This ensures the stability of the tilting frame 221 and avoids jamming during the sliding process, which could prevent the tilting frame 221 from tilting smoothly.

[0052] In some preferred embodiments, the fixed base 110 is further provided with a limiting groove 112 communicating with the sliding channel 111. The first drive assembly 230 is provided with a limiting plate 233, which passes through the limiting groove 112 and is connected to the lifting frame 120. When the limiting plate 233 abuts against the top wall of the limiting groove 112, the lifting frame 120 stops rising, and the first drive member 231 drives the arc-shaped rack 222, thereby driving the tilting frame 221 to tilt. When the lifting frame 120 descends until the limiting plate 233 abuts against the bottom wall of the limiting groove 112, the lifting frame 120 stops descending. In this way, the positioning accuracy of the lifting frame 120 can be guaranteed without the need for a separate control system to control the positioning accuracy of the first drive member 231.

[0053] In some other embodiments, the flipping device 10 further includes a first sensing structure for sensing the flipping position of the flipping frame 221. When the first driving member 231 drives the flipping frame 221 to flip to a first preset flipping position, the first sensing structure triggers a control signal to control the first driving member 231 to stop driving, thereby achieving flipping. When the first driving member 231 drives the flipping frame 221 to flip to a second preset flipping position, the first sensing structure triggers a control signal to control the first driving member 231 to stop driving, so that the flipping frame 221 is reset. This avoids the problem of the flipping function of the flipping frame 221 failing due to continuous driving of the first driving member 231, thereby making the overall structure more reliable. Preferably, the first sensing structure can be a magnetic induction switch.

[0054] In some preferred embodiments, please refer to Figure 2 , Figure 2 The diagram illustrates the structural relationship between the second drive assembly 130 and the lifting frame 120 in this embodiment of the invention. Specifically, the lifting mechanism 100 further includes a second drive assembly 130, which is driven and connected to the lifting frame 120. The second drive assembly 130 drives the lifting frame 120 to rise and fall, thereby causing the lifting frame 120 to drive the tilting frame 221 and the first drive assembly 230 to rise and fall, thus enabling the tilting frame 221 to adjust its distance from the ground, thereby ensuring the reliability of the tilting mechanism.

[0055] Furthermore, the flipping device 10 also includes a second sensing structure, which senses the lifting position of the lifting frame 120. When the lifting frame 120 is raised to the first preset lifting position, the second sensing structure triggers a control signal to stop the second drive assembly 130 from driving. Then, the first drive component 231 drives the flipping frame 221 to flip. After the flipping is completed, when the second drive assembly 130 drives the lifting frame 120 to descend to the second preset lifting position, the second sensing structure triggers a control signal to stop the second drive assembly 130 from driving. This avoids the problem of mechanical interference between the flipping frame 221 and other components, leading to damage, when the flipping frame 221 reaches the preset position and the second drive assembly 130 continues to drive. Preferably, the second sensing structure can be a magnetic induction switch.

[0056] In some preferred embodiments, the second drive assembly 130 includes a drive cylinder 131 with a piston rod 132, the output end of which is connected to the lifting frame 120. The drive cylinder 131 drives the piston rod 132 to extend and retract. When the piston rod 132 extends, it moves the lifting frame 120 away from the fixed seat 110, thereby causing the lifting frame 120 to lift the tilting frame 221 and the first drive assembly 230. When the piston rod 132 retracts, it moves the lifting frame 120 closer to the fixed seat 110, thereby causing the lifting frame 120 to lower the tilting frame 221 and the first drive assembly 230.

[0057] Example 3:

[0058] This embodiment, based on the above embodiments, provides a conveying device 20. Please refer to the appendix. Figure 4 .

[0059] A conveying device 20 includes a roller conveyor 300 and the aforementioned overturning device 10.

[0060] The roller line 300 is located below the tilting frame 221.

[0061] In this embodiment, after the lifting frame 120 drives the tilting frame 221 to descend to the preset position, the roller conveyor 300 is started. During the rolling process, the roller conveyor 300 carries the tilted workpiece out of the tilting frame 221, thereby transporting the tilted workpiece to the next station, ensuring the compactness of the overall structure and saving the space occupied by the overall equipment.

[0062] In some other embodiments, after the lifting frame 120 drives the tilting frame 221 to descend to the second lifting preset position, the tilting workpiece can be pushed out of the tilting frame 221 by manual operation. At this time, the roller line 300 does not need to be equipped with a drive mechanism, so that the tilting workpiece can be removed from the tilting frame 221.

[0063] In some preferred embodiments, the roller conveyor 300 includes a plurality of rollers 310 arranged in an array. As the rollers 310 roll, they move the rotated workpiece, causing it to detach from the rotating frame 221. This eliminates the need for manual removal or additional clamping mechanisms to unload the rotated workpiece and transport it to the next station. It is understood that workpieces to be rotated can also be loaded using the same method, with the rollers 310 continuously rolling, allowing the workpiece to enter the rotating frame 221.

[0064] The conveying device 20 of this utility model has a lifting mechanism 100 that is movably arranged in the vertical direction. A tilting frame 221 is rotatably connected to the lifting mechanism 100 via a rotating shaft 210. An arc-shaped rack 222 is connected to the tilting frame 221, and the center of the arc of the rack 222 is aligned with the axis of the rotating shaft 210. A first drive assembly 230 drives the arc-shaped rack 222 to rotate, thereby causing the tilting frame 221 to rotate, and thus enabling the tilting frame 221 to tilt. In this way, the first drive assembly 230 can drive the tilting frame 221 to rotate with less effort, thereby reducing energy consumption. Furthermore, since the tilting frame 221 can be raised and lowered in the vertical direction, the distance between the tilting frame 221 and the ground is not fixed, thus allowing the workpiece to be tilted in its original position.

[0065] In this utility model, unless otherwise explicitly 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. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0066] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this utility model is in use. They are only for the convenience of describing this utility model 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. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0067] Furthermore, terms such as "horizontal," "vertical," and "sag" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0068] In this invention, unless otherwise expressly specified and limited, "above or below" the first feature may include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on" the first feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the first feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0069] Although the description of this utility model has been given in conjunction with the specific embodiments described above, it is obvious to those skilled in the art that many substitutions, modifications, and variations can be made based on the above description. Therefore, all such substitutions, modifications, and variations are included within the spirit and scope of the appended claims.
