Description

Technical Field

[0001] This utility model belongs to the field of profile processing, and specifically relates to a profile flipping device. Background Technology

[0002] With the rapid development of modern industry and the increasing variety of processing methods, laser processing methods, which were previously widely used in sheet metal, automotive, and plastics industries, are gradually being extended to the processing of profiles and medium-thick plates. In existing production methods, the flipping of profiles and other workpieces requires coordination with overhead cranes, resulting in high worker workload and low efficiency. Utility Model Content

[0003] In view of the above problems, this application provides a profile flipping device that can flip and position profiles without the need for a vehicle or external assistance.

[0004] This application provides a profile flipping device, which includes a support mechanism and two flipping mechanisms. The support mechanism has a second support surface for supporting the profile. The two flipping mechanisms are located on opposite sides of the second support surface along a first direction. Each flipping mechanism includes a first positioning component, a first driving component, and a lifting component. The first positioning component is used to releasably fix the profile and has a first support surface for supporting the profile. The first driving component is used to drive the first positioning component to rotate about a first axis, which is parallel to the first direction. The lifting component is used to drive the first positioning component to move along the direction of gravity, so that the first positioning component is located above the second support surface, where the direction of gravity is perpendicular to the first direction.

[0005] Specifically, during use, the first supporting surface is first rotated along the first axis by the flipping mechanism, making it parallel to the second supporting surface. Then, the lifting assembly drives the first positioning assembly to move, making the first and second supporting surfaces coplanar. The profile is then placed on the first and second supporting surfaces and fixed by the first positioning assembly for processing. Next, the lifting assembly drives the first positioning assembly to move along the direction of gravity, making the first supporting surface higher than the second supporting surface. This positions the profile above the second supporting surface, preventing interference from the second supporting surface. Subsequently, the first driving component drives the first positioning assembly to rotate, causing the profile to rotate. The lifting assembly then drives the first positioning assembly to move along the direction of gravity, bringing the profile into contact with the second supporting surface, completing the flipping of the profile. Finally, the first positioning assembly releases the profile and is driven by the first driving assembly to rotate around the first axis to reset and re-fix the profile for subsequent processing.

[0006] In the above technical solution, by setting a flipping mechanism, the profile flipping device can flip the profile without the aid of external force, thereby reducing the labor intensity of workers and improving processing efficiency.

[0007] In some embodiments, the first positioning component includes a first support member and two first limiting blocks. The first support member has a first supporting surface; the two first limiting blocks are movably disposed on the first support member along the extending direction of the first support member, and a first limiting gap for accommodating a profile is provided between the two first limiting blocks, wherein the extending direction of the first support member is perpendicular to the first direction.

[0008] In the above technical solution, a first limiting gap for accommodating the profile is provided between the two first limiting blocks, so that the size of the first limiting gap can be adjusted by moving the two first limiting blocks along the extension direction of the first support member; on the one hand, the size of the first limiting gap can be adjusted so that the first limiting block abuts against the profile to fix the profile; on the other hand, the size of the first limiting gap can be adjusted so that the first limiting block can be adapted to profiles of different widths, so that the first positioning component can position profiles of different sizes.

[0009] In some embodiments, the first positioning component further includes a first double-ended lead screw and a second driving member. The first double-ended lead screw is disposed on the first support member, and the two first limiting blocks are respectively provided with first threaded holes that are threadedly engaged with the first double-ended lead screw. The first double-ended lead screw rotates to drive the two first limiting blocks to move closer or further apart from each other; the second driving member is used to drive the first double-ended lead screw to rotate.

[0010] In the above technical solution, the first double-headed lead screw drives the two first limit blocks to move, thereby enabling one driving component to drive the first limit blocks to move, reducing the number of driving components and making the structure simple and easy to implement.

[0011] In some embodiments, the support mechanism includes a guide rail and a second positioning component. The guide rail extends along the first direction; the second positioning component is movably disposed on the guide rail along the first direction, and the second support surface is disposed on the second positioning component.

[0012] In the above technical solution, the second positioning component can be movably disposed on the guide rail along the first direction, so that by adjusting the second positioning component, the second positioning component can be positioned close to the center of gravity of the profile, thereby enabling the second positioning component to support the profile more stably.

[0013] In some embodiments, the lifting assembly includes a base and a linear module. The base is movably disposed on the guide rail along the first direction; the linear module is disposed on the base and extends along the direction of gravity, and the first positioning component is disposed at the output end of the linear module.

[0014] In the above technical solution, the base can move along the first direction, thereby enabling the base to drive the first positioning component to move along the first direction, and thus enabling the two first positioning components to position profiles of different lengths.

[0015] In some embodiments, the second positioning component includes a second support member and two second limiting blocks. The second support member has a second support surface; the two second limiting blocks are movably disposed on the first support member along a second direction, and a second limiting gap for accommodating the profile is provided between the two second limiting blocks, wherein the first direction, the second direction, and the gravity direction are perpendicular to each other.

[0016] In the above technical solution, a second limiting gap for accommodating the profile is provided between the two second limiting blocks, so that the size of the second limiting gap can be adjusted by moving the two second limiting blocks along the second direction; on the one hand, the second limiting block can be made to abut against the profile to fix the profile by adjusting the size of the second limiting gap; on the other hand, the second limiting block can be adapted to profiles of different widths by adjusting the size of the second limiting gap, so that the second positioning component can position profiles of different sizes.

[0017] In some embodiments, the second positioning assembly further includes a second double-ended lead screw and a third driving member. The second double-ended lead screw is disposed on the second support member, and the two second limiting blocks are respectively provided with second threaded holes that are threadedly engaged with the second double-ended lead screw. The second double-ended lead screw rotates to drive the two second limiting blocks to move closer or further apart from each other; the third driving member is used to drive the second double-ended lead screw to rotate.

[0018] In the above technical solution, the second double-headed lead screw drives the two second limit blocks to move, thereby enabling one driving component to drive the second limit blocks to move, reducing the number of driving components and making the structure simple and easy to implement.

[0019] In some embodiments, the second support member includes a first body and a second body. The two second limiting blocks are movably disposed on the first body along the second direction; the second body is movably disposed on the side of the first body away from the guide rail along the second direction, and the second body has the second support surface.

[0020] In the above technical solution, by movably positioning the second body along a second direction on the side of the first body away from the guide rail, when the profile is driven by the second limiting block to move towards the center position of the first body, the second body can be driven to follow the profile under the action of friction, thereby reducing the relative sliding between the second support surface and the profile, and reducing the wear of the profile on the second support surface. This improves the positioning accuracy of the second support surface during use.

[0021] In some embodiments, the second support member includes an elastic member. The two ends of the elastic member are respectively connected to the first body and the second body, and the elastic member is used to provide an elastic force to the second body to guide the second body to overlap with the second body at its midpoint in the second direction along the direction of gravity.

[0022] In the above technical solution, when the second positioning component drives the profile to be above the second support surface for flipping, the elastic element can drive the second body to reset, so that when the second limiting block is driven to move to the middle position of the first body next time, there is sufficient movement stroke between the second body and the first body.

[0023] In some embodiments, the profile flipping device further includes a detection mechanism. The detection mechanism is used to detect the contact between the first support surface and the profile, and / or, the detection mechanism is used to detect the contact between the second support surface and the profile.

[0024] In the above technical solution, the placement of the profile is detected by a testing agency, which improves the stability of the profile flipping device in fixing and releasing the profile. Attached Figure Description

[0031] The embodiments of this application will now be described in detail with reference to the accompanying drawings.

Therefore, they should not be construed as limitations on this application.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0034] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; 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; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0035] With the rapid development of modern industry and the increasing variety of processing methods, laser processing methods, which were previously widely used in sheet metal, automotive, and plastics industries, are gradually being extended to the processing of profiles and medium-thick plates. In existing production methods, the flipping of profiles and other workpieces requires coordination with overhead cranes, resulting in high worker workload and low efficiency.

[0036] To solve the above technical problems, refer to Figures 1-5This application provides a profile flipping device including a support mechanism 10 and two flipping mechanisms 20. The support mechanism 10 has a second support surface for supporting the profile. The two flipping mechanisms 20 are located on opposite sides of the second support surface along a first direction X. Each flipping mechanism 20 includes a first positioning component 21, a first driving component 22, and a lifting component 23. The first positioning component 21 is used to releasably fix the profile and has a first support surface for supporting the profile. The first driving component 22 is used to drive the first positioning component 21 to rotate around a first axis parallel to the first direction X. The lifting component 23 is used to drive the first positioning component 21 to move along the gravity direction Z, so that the first positioning component 21 is located above the second support surface, and the gravity direction Z is perpendicular to the first direction X.

[0037] The second support surface is the surface on the support mechanism 10 used to support the profile. The support profile refers to the surface where the second support surface abuts against the profile along the direction of gravity Z.

[0038] The first support surface is the surface on the support mechanism 10 used to support the profile. The support profile refers to the first support surface that abuts against the profile along the direction of gravity Z.

[0039] The first driving member 22 is a driving component for driving the first positioning component 21 to rotate. For example, the first driving member 22 can be a motor or a rotary cylinder.

[0040] In some embodiments, the flipping mechanism 20 further includes a turntable, which is rotatably mounted on the lifting assembly 23. A first positioning assembly 21 is mounted on the turntable, and a first driving member 22 is a drive motor mounted on the lifting assembly 23. The output end of the drive motor is used to drive the turntable to rotate.

[0041] Specifically, during use, the first supporting surface is first rotated along the first axis by the flipping mechanism 20, making the first supporting surface parallel to the second supporting surface. Then, the lifting component 23 drives the first positioning component 21 to move, making the first and second supporting surfaces coplanar. The profile is then placed on the first and second supporting surfaces and fixed by the first positioning component 21 for processing. Next, the lifting component 23 drives the first positioning component 21 to move along the direction of gravity Z, making the first supporting surface higher than the second supporting surface. This positions the profile above the second supporting surface, preventing interference from the second supporting surface. Subsequently, the first driving component 22 drives the first positioning component 21 to rotate, causing the profile to rotate. Then, the lifting component 23 drives the first positioning component 21 to move along the direction of gravity Z, causing the first positioning component 21 to bring the profile into contact with the second supporting surface, completing the flipping of the profile. Finally, the first positioning component 21 releases the profile and is driven by the first driving component to rotate around the first axis to reset, re-fixing the profile for subsequent processing.

[0042] In this technical solution, by setting a flipping mechanism 20, the profile flipping device can flip the profile without the aid of external force, thereby reducing the labor intensity of workers and improving processing efficiency.

[0043] According to some embodiments of this application, the first positioning component 21 includes a first support member 211 and two first limiting blocks 212. The first support member 211 has a first support surface; the two first limiting blocks 212 are movably disposed on the first support member 211 along the extending direction of the first support member 211, and a first limiting gap for accommodating the profile is provided between the two first limiting blocks 212, and the extending direction of the first support member 211 is perpendicular to the first direction X.

[0044] Understandably, when the first driving member 22 drives the first support member 211 to rotate, the rotation angle should be controlled within 90° so that the profile can still be supported by one of the two first limiting blocks 212 after rotation.

[0045] In this technical solution, a first limiting gap for accommodating the profile is provided between the two first limiting blocks 212, so that the size of the first limiting gap can be adjusted by moving the two first limiting blocks 212 along the extension direction of the first support member 211. On the one hand, the size of the first limiting gap can be adjusted so that the first limiting block 212 abuts against the profile to fix the profile; on the other hand, the size of the first limiting gap can be adjusted so that the first limiting block 212 can be adapted to profiles of different widths, so that the first positioning component 21 can position profiles of different sizes.

[0046] According to some embodiments of this application, the first positioning component 21 further includes a first double-ended lead screw 213 and a second driving member 214. The first double-ended lead screw 213 is disposed on the first support member 211, and two first limiting blocks 212 are respectively provided with first threaded holes that are threadedly engaged with the first double-ended lead screw 213. The first double-ended lead screw 213 rotates to drive the two first limiting blocks 212 to move closer or further apart from each other; the second driving member 214 is used to drive the first double-ended lead screw 213 to rotate.

[0047] Understandably, a double-ended lead screw refers to a lead screw with external threads at both ends, and the threads rotate in the opposite direction. Two first limiting blocks 212 respectively engage with the external threads at both ends of the first double-ended lead screw 213. This allows the two first limiting blocks 212 to move towards or away from each other when the first double-ended lead screw 213 rotates. This enables the two first limiting blocks 212 to simultaneously clamp or release the profile, increasing the profile's centering accuracy and reducing positioning errors.

[0048] In some embodiments, the second drive element 214 may be a drive motor.

[0049] In this technical solution, the first double-headed lead screw 213 drives the two first limiting blocks 212 to move, thereby enabling one driving component to drive the first limiting blocks 212 to move, reducing the number of driving components and making the structure simple and easy to implement.

[0050] According to some embodiments of this application, the support mechanism 10 includes a guide rail 11 and a second positioning component 12. The guide rail 11 extends along a first direction X; the second positioning component 12 is movably disposed on the guide rail 11 along the first direction X, and a second support surface is disposed on the second positioning component 12.

[0051] In some embodiments, the second positioning components 12 are a plurality of components spaced apart along a first direction.

[0052] In this technical solution, the second positioning component 12 can be movably disposed on the guide rail 11 along the first direction X, so that by adjusting the second positioning component 12, the second positioning component 12 can be positioned close to the center of gravity of the profile, thereby enabling the second positioning component 12 to support the profile more stably.

[0053] According to some embodiments of this application, the lifting assembly 23 includes a base 231 and a linear module 232. The base 231 is movably disposed on the guide rail 11 along a first direction X; the linear module 232 is disposed on the base 231 and extends along the gravity direction Z, and a first positioning component 21 is disposed at the output end of the linear module 232.

[0054] In some embodiments, the second positioning component 12 is provided with a driving member, and / or the base 231 is provided with a driving member, the output end of the driving member is provided with a driving wheel adapted to the guide rail 11, the driving member drives the driving wheel to rotate to drive the second positioning component 12 to move, and / or the driving member drives the driving wheel to rotate to drive the base 231 to move.

[0055] In this technical solution, the base 231 can move along the first direction X, thereby enabling the base 231 to drive the first positioning component 21 to move along the first direction X, and thus enabling the two first positioning components 21 to position profiles of different lengths.

[0056] According to some embodiments of this application, the second positioning component 12 includes a second support member 121 and two second limiting blocks 122. The second support member 121 has a second support surface; the two second limiting blocks 122 are movably disposed on the first support member 211 along the second direction Y, and a second limiting gap for accommodating the profile is provided between the two second limiting blocks 122, wherein the first direction X, the second direction Y and the gravity direction Z are perpendicular to each other.

[0057] In this technical solution, a second limiting gap for accommodating the profile is provided between the two second limiting blocks 122, so that the size of the second limiting gap can be adjusted by moving the two second limiting blocks 122 along the second direction Y; on the one hand, the second limiting block 122 can be made to abut against the profile to fix the profile by adjusting the size of the second limiting gap; on the other hand, the second limiting block 122 can be adapted to profiles of different widths by adjusting the size of the second limiting gap, so that the second positioning component 12 can position profiles of different sizes.

[0058] According to some embodiments of this application, the second positioning component 12 further includes a second double-ended lead screw and a third driving member 123. The second double-ended lead screw is disposed on the second support member 121, and two second limiting blocks 122 are respectively provided with second threaded holes that are threadedly engaged with the second double-ended lead screw. The second double-ended lead screw rotates to drive the two second limiting blocks 122 to move closer or further apart from each other; the third driving member 123 is used to drive the second double-ended lead screw to rotate.

[0059] Understandably, a double-ended lead screw refers to a lead screw with external threads at both ends, and the external threads rotate in the opposite direction. Two second limiting blocks 122 respectively engage with the external threads at both ends of the second double-ended lead screw. This allows the two second limiting blocks 122 to move towards or away from each other when the second double-ended lead screw rotates, thereby clamping or releasing the profile, increasing the profile's centering accuracy, and thus reducing the profile's positioning error.

[0060] In some embodiments, the third drive element 123 can be a drive motor. Exemplarily, the third drive element 123 can be a servo motor with a torque mode. In torque mode, the third drive element 123 monitors the clamping torque in real time through a closed-loop feedback mechanism and dynamically adjusts the output torque according to a preset threshold, ensuring that the clamping force is always maintained near the target value. This avoids insufficient clamping force due to insufficient contact surface in traditional pressure control when the profile size is too small. It also avoids overload of the fixed pressure (e.g., squeezing the positioning component when the profile is too large) or loosening (e.g., not clamping tightly when the profile is too small) caused by fluctuations in profile size. This improves positioning accuracy.

[0061] In this technical solution, the second double-headed lead screw drives the two second limit blocks 122 to move, thereby enabling one driving component to drive the second limit blocks 122 to move, reducing the number of driving components and making the structure simple and easy to implement.

[0062] According to some embodiments of this application, the second support member 121 includes a first body 1211 and a second body 1212. Two second limiting blocks 122 are movably disposed on the first body 1211 along the second direction Y; the second body 1212 is movably disposed on the side of the first body 1211 away from the guide rail 11 along the second direction Y, and the second body 1212 has a second support surface.

[0063] In this technical solution, by movably positioning the second body 1212 along the second direction Y on the side of the first body 1211 away from the guide rail 11, the second body 1212 can be driven by friction to follow the profile when the profile is moved towards the center position of the first body 1211 by the second limiting block 122. This reduces the relative sliding between the second support surface and the profile, and reduces the wear of the profile on the second support surface. It also improves the positioning accuracy of the second support surface during use.

[0064] According to some embodiments of this application, the second support member 121 includes an elastic member 1213. The two ends of the elastic member 1213 are respectively connected to the first body 1211 and the second body 1212. The elastic member 1213 is used to provide an elastic force to the second body 1212 to guide the second body 1212 to overlap with the second body 1212 at the middle of the second direction Y along the gravity direction Z.

[0065] In some embodiments, a guide rod 12121 is provided on the side of the second body 1212 facing the first body 1211, and a mounting block 12111 is provided on the side of the first body 1211 facing the second body 1212. The mounting block 12111 is provided with a guide hole adapted to the guide rod 12121. The elastic element 1213 is a spring. There are two elastic elements 1213 disposed on opposite sides of the mounting block 12111 in the second direction Y. One end of the elastic element 1213 is connected to the second body 1212, and the other end of the elastic element 1213 is connected to the mounting block 12111.

[0066] In this technical solution, when the second positioning component 12 drives the profile to be positioned above the second support surface for flipping, the elastic element 1213 can drive the second body 1212 to reset, so that when the second limiting block 122 is driven to move towards the middle position of the first body 1211 next time, there is sufficient movement stroke between the second body 1212 and the first body 1211.

[0067] According to some embodiments of this application, the profile flipping device further includes a detection mechanism. The detection mechanism is used to detect the contact between the first support surface and the profile, and / or, the detection mechanism is used to detect the contact between the second support surface and the profile.

[0068] In some embodiments, the detection mechanism is a laser sensor, which has a built-in laser emitter (such as a semiconductor laser) that can directionally emit a beam of visible or invisible light (typically in the infrared band). When the beam hits the workpiece surface, it is reflected, and some energy returns to the sensor receiver (such as a photodiode). If the sensor does not receive a reflected signal (or the signal strength is below a threshold), it determines that there is "no profile"; if it receives a signal, it determines that there is "profile".

[0069] By testing the placement of the profiles through a testing agency, the stability of the profile flipping device in fixing and releasing the profiles is improved.

[0070] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0071] The above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit this application. For those skilled in the art, this application can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
