DETAILED DESCRIPTION

[0033] The technical scheme in the utility model will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. Although the representative embodiments of the utility model have been described in detail, it will be understood by those skilled in the art that the utility model can be modified and changed in various ways without departing from the scope of the utility model. Therefore, the scope of the utility model should not be limited to the embodiments, but should be defined by the attached claims and their equivalents.

[0034] The utility model provides a material flipping mechanism, including a first support column, a second support column and a rotating frame 1-5; a clamping area for placing materials is formed in the rotating frame 1-5; the two ends of the rotating frame 1-5 are respectively rotatably connected to the first support column and the second support column, and the rotation axis of the first support column is coaxially arranged with the rotation axis of the second support column; the rotating frame 1-5 is provided with a plurality of clamping components 1-6 for clamping materials, and each of the clamping components 1-6 is located in the clamping area. When in use, the material 1-8 to be flipped is transferred to the clamping area of ​​the rotating frame 1-5 by hoisting, manipulator or other feasible methods, and the clamping component 1-6 is started to clamp the material 1-8. Then the rotating frame 1-5 is synchronously rotated around the first support column and the second support column to drive the material 1-8 to flip. Finally, the clamping component 1-6 is released to take out the material 1-8.

[0035] In order to improve the applicability of the material turning mechanism, the first support column is a fixed support column 1-2; the second support column is a movable support column 1-3 that can move relative to the fixed support column 1-2.

[0036] Specifically, the rotating frame 1-5 includes a fixed half frame 1-52 and a movable half frame 1-51, the fixed half frame 1-52 is slidably connected to the movable half frame 1-51 and the two are enclosed to form a clamping area for placing materials, and the sliding direction between the fixed half frame 1-52 and the movable half frame 1-51 is the same as the moving direction of the movable support column 1-3; the fixed half frame 1-52 is rotatably connected to the fixed support column 1-2; the movable half frame 1-51 is rotatably connected to the movable support column 1-3, and the rotation axis of the fixed half frame 1-52 is coaxially arranged with the rotation axis of the movable half frame 1-51; the fixed half frame 1-52 and the movable half frame 1-51 are both provided with a plurality of clamping components 1-6 for clamping materials 1-8, and each of the clamping components is located in the clamping area. When in use, adjust the relative position between the mobile support column 1-3 and the fixed support column 1-2, and the mobile half frame 1-51 moves synchronously toward the fixed support column 1-2 under the drive of the mobile support column 1-3, reducing the volume of the rotating frame 1-5 so that its clamping area reaches the preset size of the material 1-8 to be flipped. Use hoisting, manipulator or other feasible methods to transfer the material 1-8 to be flipped into the rotating frame 1-5, and start the clamping assembly 1-6 to clamp the material 1-8. Then make the fixed half frame 1-52 and the mobile half frame 1-51 of the rotating frame 1-5 rotate synchronously around the fixed support column 1-2 and the mobile support column 1-3, driving the material 1-8 to flip. Finally, release the clamping assembly 1-6 and take out the material 1-8.

[0037] Specifically, the multiple clamping components 1-6 on the fixed half frame 1-52 and the multiple clamping components 1-6 on the movable half frame 1-51 are arranged symmetrically one by one to ensure that the material 1-8 is subjected to uniform force when clamped.

[0038] Furthermore, the clamping assembly 1-6 includes a first clamping member 1-61, a first driving member 1-62 for driving the first clamping member 1-61 to move in a horizontal direction, a second clamping member 1-63, a second driving member 1-64 for driving the second clamping member 1-63 to move in a horizontal direction, and a third driving member 1-65 for driving the first clamping member 1-61 and the second clamping member 1-63 to move relative to each other; the first driving member 1-62 and the second driving member 1-64 are installed on the rotating frame 1-5; the clamping surfaces of the first clamping member 1-61 and the second clamping member 1-63 are arranged opposite to each other. When in use, the second driving member 1-64 first drives the second clamping member 1-63 to extend in the horizontal direction, and the material 1-8 to be flipped is placed on the clamping surface of the second clamping member 1-63. Then, the first driving member 1-62 drives the first clamping member 1-61 to extend in the horizontal direction, so that the first clamping member 1-61 is located above the second clamping member 1-63. The third driving member 1-65 is started to drive the first clamping member 1-61 to move toward the second clamping member 1-63, and the material 1-8 is clamped between the first clamping member 1-61 and the second clamping member 1-63. After flipping, the first clamping member 1-61 is located below the second clamping member 1-63, and the third driving member 1-65 is recovered to release the clamping state. At this time, the material 1-8 is placed on the clamping surface of the first clamping member 1-61, and then the second driving member 1-64 is used to recover the second clamping member 1-63, exposing the material 1-8, so that the manipulator or other equipment can take out the material 1-8. After the material 1-8 is taken out, the first driving member 1-62 recovers the first clamping member 1-61. In the next round of clamping, the first clamping member 1-61 is first extended to place the material 1-8, and then the second clamping member 1-63 is extended.

[0039] Specifically, the first clamping member 1-61 includes a first clamping plate 1-611 and a first clamping block 1-612; the first clamping plate 1-611 is connected to the output end of the first driving member 1-62; the third driving member 1-65 is installed on the first clamping plate; the first clamping block 1-612 is installed at the output end of the third driving member 1-65.

[0040] Furthermore, N groups of clamping assemblies 1-6 are provided on the rotating frame 1-5, each group of clamping assemblies 1-6 includes two clamping assemblies 1-6, and the clamping assemblies 1-6 in the same group are arranged symmetrically along the rotation axis; the clamping assemblies 1-6 on the same side of the rotation axis are arranged at intervals, and there is an angle between the movement directions of adjacent clamping assemblies 1-6 on the horizontal plane. By adjusting the position of the clamping assemblies 1-6, it is adapted to the stable clamping of materials 1-8 of different sizes.

[0041] In an optimized implementation, the rotating frame 1-5 is a rectangular structure, which is divided into a fixed half frame 1-52 and a movable half frame 1-51 in the length direction. The rotation axes 1-4 of the fixed half frame 1-52 and the movable half frame 1-51 are coincident and are both located on the center line of the rotating frame 1-5. There are eight clamping components 1-6 in total, four of which are arranged at the four corners of the rotating frame 1-5, and the clamping parts move in the radial direction on the horizontal plane. The other four are symmetrically arranged on both sides of the rotation point of the fixed half frame 1-52 and the rotation point of the movable half frame 1-51, and the clamping parts move in the horizontal plane in the length direction of the rotating frame 1-5. The corresponding clamping components 1-6 on the fixed half frame 1-52 and the movable half frame 1-51 move in opposite directions on the horizontal plane. When the size of the material 1-8 to be flipped is small, only the four clamping components 1-6 near the rotation point can be used for clamping. When the size of the material 1-8 to be flipped is large, the clamping components 1-6 arranged at the four corners are activated.

[0042] Since the pole frame, pole plate and other materials 1-8 are large in size and have low hardness, in order to avoid deformation and damage during the flipping process, a centering component 1-7 for adjusting the center position of the material 1-8 to be flipped is provided on the rotating frame 1-5. By fine-tuning the material 1-8 through the centering component 1-7, the actual clamping area of ​​each clamping component 1-6 can be the same, the clamping is more secure, and the product is ensured not to be deformed due to problems such as rotational inertia.

[0043] Specifically, the centering component 1-7 includes a first V-groove 1-71, a driving cylinder 1-73 and a second V-groove 1-72; the first V-groove 1-71 is installed on the movable half frame 1-51; the driving cylinder 1-73 is installed on the fixed half frame 1-52; the second V-groove 1-72 is installed at the output end of the driving cylinder 1-73; the V-shaped opening of the first V-groove 1-71 and the V-shaped opening of the second V-groove 1-72 are arranged relative to each other. The V-groove is used to center the pole frame, pole plate and other materials 1-8. In another embodiment, the driving cylinder 1-73 can also be installed on the movable half frame 1-51, the first V-groove 1-71 is installed at the output end of the driving cylinder 1-73; the second V-groove 1-72 is installed on the fixed half frame 1-52. The position of the first V-groove 1-71 or the second V-groove 1-72 is adjusted by the driving cylinder 1-73, and the material 1-8 is fine-tuned to achieve centering. In order to avoid excessive static friction and the possibility of centering failure, the angle of the V-groove is preferably 160-175°.

[0044] In one embodiment, the material turning mechanism includes the above-mentioned refined clamping assembly 1-6 and V-groove centering assembly 1-7, and the method of using the same is as follows: adjust the relative position between the mobile support column 1-3 and the fixed support column 1-2, and the mobile half frame 1-51 moves synchronously toward the fixed support column 1-2 under the drive of the mobile support column 1-3, so as to reduce the volume of the rotating frame 1-5 so that its internal space reaches the preset size of the material 1-8 to be turned. Multiple clamping assemblies 1-6 are started synchronously, and first the second driving member 1-64 drives the second clamping member 1-63 to extend in the horizontal direction, and the material 1-8 to be turned is transferred to the rotating frame 1-5 by hoisting, manipulator or other feasible methods, and placed on the clamping surface of the second clamping member 1-63 of the multiple clamping assemblies 1-6. Fine-tune the driving cylinder 1-73, and use the first V-groove 1-71 and the second V-groove 1-72 to center the material 1-8, so that the clamping area of ​​the material 1-8 on each clamping assembly 1-6 is the same. Then, the first driving member 1-62 drives the first clamping member 1-61 to extend horizontally, so that the first clamping member 1-61 is located above the second clamping member 1-63, and the third driving member 1-65 is started to drive the first clamping member 1-61 to move toward the second clamping member 1-63, so that the material 1-8 is clamped between the first clamping member 1-61 and the second clamping member 1-63. The fixed half frame 1-52 and the movable half frame 1-51 of the rotating frame 1-5 are synchronously rotated around the fixed support column 1-2 and the movable support column 1-3, so as to drive the material 1-8 to turn over. After flipping, the first clamping member 1-61 is located below the second clamping member 1-63, and the third driving member 1-65 is recovered to release the clamping state. At this time, the material 1-8 is placed on the clamping surface of the first clamping member 1-61, and then the second driving member 1-64 is used to recover the second clamping member 1-63 to expose the material 1-8, so that the robot or other equipment can take out the material 1-8. After the material 1-8 is taken out, the first driving member 1-62 recovers the first clamping member 1-61.

[0065] The clamping assembly 1-6 includes a first clamping member 1-61, a first driving member 1-62 for driving the first clamping member 1-61 to move in a horizontal direction, a second clamping member 1-63, a second driving member 1-64 for driving the second clamping member 1-63 to move in a horizontal direction, and a third driving member 1-65 for driving the first clamping member 1-61 and the second clamping member 1-63 to move relative to each other; the first driving member 1-62 and the second driving member 1-64 are installed on the rotating frame 1-5; the first clamping member 1-61 includes a first clamping plate 1-611 and a first clamping block 1-612; the first clamping plate 1-611 is connected to the output end of the first driving member 1-62; the third driving member 1-65 is installed on the first clamping plate; the first clamping block 1-612 is installed at the output end of the third driving member 1-65; the second clamping member 1-63 is connected to the output end of the second driving member 1-64; the clamping surfaces of the first clamping block 1-612 and the second clamping member 1-63 are arranged relatively.

[0066] There are eight clamping assemblies 1-6 in total, four of which are arranged at the four corners of the rotating frame 1-5, and the corresponding first clamping members 1-61 and second clamping members 1-63 move in radial directions on the horizontal plane, and the corresponding clamping assemblies 1-6 on the fixed half frame 1-52 and the movable half frame 1-51 move in opposite directions on the horizontal plane. The other four are symmetrically arranged on both sides of the first V-shaped groove 1-71 and the second V-shaped groove 1-72, and the corresponding first clamping members 1-61 and second clamping members 1-63 move in the horizontal plane in the length direction of the rotating frame 1-5.

[0067] The method of using the above material turning mechanism is as follows:

[0068] 1. First, determine the size of materials 1-8 transported by hoisting, manipulator or other feasible means. Materials 1-8 with a diameter of 1500-1900mm are defined as small-sized materials, and materials 1-8 with a diameter of 1900-2500mm are defined as large-sized materials.

[0069] 2. When turning over a large-sized material 1-8, the mobile support column 1-3 moves on the guide rail 1-11 toward the fixed support column 1-2, and the mobile half frame 1-51 moves synchronously toward the fixed half frame 1-52 driven by the mobile support column 1-3, reducing the surface area of ​​the rotating frame 1-5 until the mobile support column 1-3 stops moving after the surface area reaches the preset size of the material 1-8 to be turned over. The clamping components 1-6 located at the four corners of the rotating frame 1-5 are started synchronously, and first the second driving component 1-64 drives the second clamping component 1-63 to extend radially on the horizontal plane, and the material 1-8 to be turned over is transferred to the rotating frame 1-5 by hoisting, manipulator or other feasible methods, and placed on the clamping surfaces of the second clamping components 1-63 of the four clamping components 1-6. Fine-tune the drive cylinder 1-73, and use the first V-groove 1-71 and the second V-groove 1-72 to center the material 1-8, so that the clamping area of ​​the material 1-8 on each second clamping member 1-63 is the same. Then the first drive member 1-62 drives the first clamping member 1-61 to extend radially on the horizontal plane, so that the first clamping block 1-612 of the first clamping member 1-61 is located above the second clamping member 1-63, and the third drive member 1-65 is started to drive the first clamping block 1-612 to move toward the second clamping member 1-63, and the material 1-8 is clamped between the first clamping member 1-61 and the second clamping member 1-63. Start the rotating shaft 1-4, so that the fixed half frame 1-52 and the movable half frame 1-51 of the rotating frame 1-5 rotate synchronously around the fixed support column 1-2 and the movable support column 1-3, driving the material 1-8 to flip. After flipping, the first clamping member 1-61 is located below the second clamping member 1-63, and the third driving member 1-65 is recovered to release the clamping state. At this time, the material 1-8 is placed on the clamping surface of the first clamping member 1-61, and then the second driving member 1-64 is used to recover the second clamping member 1-63 to expose the material 1-8, so that the robot or other equipment can take out the material 1-8. After the material 1-8 is taken out, the first driving member 1-62 recovers the first clamping member 1-61 to complete a round of flipping.

[0070] 3. When turning over small-sized materials 1-8, the mobile support column 1-3 moves on the guide rail 1-11 toward the fixed support column 1-2, and the mobile half frame 1-51 moves synchronously toward the fixed half frame 1-52 driven by the mobile support column 1-3, reducing the surface area of ​​the rotating frame 1-5, and the mobile support column 1-3 stops moving after the surface area reaches the preset size of the material 1-8 to be turned over. The clamping components 1-6 located on both sides of the first V-shaped groove 1-71 and the second V-shaped groove 1-72 are started synchronously, and first the second driving member 1-64 drives the second clamping member 1-63 to extend in the length direction on the horizontal plane, and the material 1-8 to be turned over is transferred to the rotating frame 1-5 by hoisting, manipulator or other feasible methods, and placed on the clamping surfaces of the second clamping members 1-63 of the four clamping components 1-6. Fine-tune the drive cylinder 1-73, and use the first V-groove 1-71 and the second V-groove 1-72 to center the material 1-8, so that the clamping area of ​​the material 1-8 on each second clamping member 1-63 is the same. Then the first drive member 1-62 drives the first clamping member 1-61 to extend in the length direction on the horizontal plane, so that the first clamping block 1-612 of the first clamping member 1-61 is located above the second clamping member 1-63, and the third drive member 1-65 is started to drive the first clamping block 1-612 to move toward the second clamping member 1-63, and the material 1-8 is clamped between the first clamping member 1-61 and the second clamping member 1-63. Start the rotating shaft 1-4, so that the fixed half frame 1-52 and the movable half frame 1-51 of the rotating frame 1-5 rotate synchronously around the fixed support column 1-2 and the movable support column 1-3, driving the material 1-8 to flip. After flipping, the first clamping member 1-61 is located below the second clamping member 1-63, and the third driving member 1-65 is recovered to release the clamping state. At this time, the material 1-8 is placed on the clamping surface of the first clamping member 1-61, and then the second driving member 1-64 is used to recover the second clamping member 1-63 to expose the material 1-8, so that the robot or other equipment can take out the material 1-8. After the material 1-8 is taken out, the first driving member 1-62 recovers the first clamping member 1-61 to complete a round of flipping.
