[0010] In some embodiments, the gripping and flipping mechanism includes a positioning platform located on the second side of the flipping module. The positioning platform is used to carry and position the material flipped to the second side of the flipping module. The gripping drive mechanism is also used to drive the two grippers away from each other to release the material after the material has been flipped to the second side of the flipping module.

[0011] In some embodiments, the positioning platform includes a placement plate and a plurality of positioning blocks, the positioning blocks being disposed on the placement plate, the plurality of positioning blocks and the placement plate together forming a positioning space, the positioning space being used to position the material on the second side of the flipping module.

[0024] Please see Figures 1 to 4 and Figures 7 to 12 The present invention provides a clamping and flipping mechanism 100, comprising a clamping module 12 and a flipping module 14. The clamping module 12 includes a clamping drive mechanism 16 and a clamping member 18. The clamping member 18 includes two grippers 20. The clamping drive mechanism 16 is connected to the two grippers 20 and is used to drive the two grippers 20 to move closer together to clamp material 200 and to move further apart to release material 200. Each gripper 20 includes a clamping surface 22 with a groove 24 for limiting the material 200. The flipping module 14 is connected to the clamping drive mechanism 16 and is used to drive the clamping module 12 to flip the clamped material 200 from a first side of the flipping module 14 to a second side opposite to the first side, thereby flipping the material 200.

[0025] The aforementioned clamping and turning mechanism 100 provides a groove 24 on the clamping surface of the gripper 20, so that the material 200 is always clamped during the material picking and turning process, thereby eliminating defects caused by material dropping and avoiding safety hazards and human factors of manual material picking to a certain extent.

[0026] Specifically, please combine Figure 1 and Figure 2 The clamping and flipping mechanism 100 can be used in the production line 1000. Optionally, in one embodiment, the production line 1000 may further include a forging press and a forming machine. The material 200 includes a first side 26 and a second side 28 facing away from each other. The forging press and the clamping and flipping mechanism 100 can be connected by a production line 300, which is located on the first side of the flipping module 14, and the forming machine is located on the second side of the flipping module 14. When the forging press outputs the material 200 to the production line 300, the first side 26 of the material 200 faces upward and the second side 28 faces downward. The material 200 is transferred to the space between two grippers 20 via the production line 300. The clamping drive mechanism 16 can drive the two grippers 20 to move closer together so that the gripper 18 clamps the material 200. At this time, the two sides of the material 200 are respectively located in the grooves 24 of the two grippers 20. The material 200 is limited by the grooves 24, ensuring that the material 200 does not fall off during the clamping and flipping process.

[0027] The flipping module 14 is connected to the clamping drive mechanism 16. The flipping module 14 is used to drive the clamping module 12 to flip the clamped material 200 from the first side of the flipping module 14 to the second side of the flipping module 14 opposite to the first side, so that the material 200 is flipped over, that is, the second side 28 of the material 200 faces up and the first side 26 faces down. The shaping machine can perform shaping processing on the second side 28 of the material 200.

[0028] The clamping drive mechanism 16 includes, but is not limited to, a cylinder. The flipping module 14 includes, but is not limited to, a rotary motor. Optionally, the flipping module 14 can drive the clamping module 12 to flip the clamped material 200 by 180 degrees. For example, when on the first side of the flipping module 14, the first surface 26 of the material 200 is vertically upward and the second surface 28 is vertically downward. After the flipping module 14 flips the material 200, the second surface 28 of the material 200 is vertically upward and the first surface 26 is vertically downward.

[0029] In one embodiment, the initial temperature of the material 200 conveyed in the assembly line 300 is relatively high (e.g., 180 to 200 degrees Celsius), and the surface of the material 200 is oily. The material of the gripper 18 is heat-resistant, and the gripping module 12 grips the material 200 through the gripper 18. The gripping surface 22 is provided with a groove 24. While the material 200 is being gripped, it can be limited by the groove 24 to prevent the material 200 from falling during the gripping and flipping process. This ensures that no material falls during the operation of the gripping and flipping mechanism 100, thereby guaranteeing product quality and avoiding safety hazards and human factors caused by manual operation.

[0030] Optionally, the groove width of the groove 24 is slightly larger than the thickness of the material 200, so that the groove 24 has a certain degree of enveloping properties.

[0031] In some implementations, please refer to Figure 3 and Figure 4 , Figure 7 and Figure 9 The gripper 20 includes a guide portion 30 and a gripping portion 32 connected to each other. The gripping portion 32 includes a gripping surface 22. A gripping space 34 is formed between the grooves 24 of the two grippers 20. In the direction of entering the gripping space 34, the distance between the guide portions 30 of the two grippers 20 gradually decreases so as to guide the material 200 into the gripping space 34 and the groove 24.

[0032] Therefore, the gripping part 32 can easily and securely grip the material 200.

[0033] Specifically, one end of the gripping part 32 is connected to the gripping drive mechanism 16, and the other end is connected to the guide part 30. Material 200 is conveyed from the assembly line 300 into the gripping space 34. Since the distance between the guide parts 30 of the two grippers 20 gradually decreases in the direction of entering the gripping space 34, when material 200 is conveyed from the assembly line 300 into the gripping space 34, the distance between the guide parts 30 of the two grippers 20 that are farther from the gripping space 34 is larger, making it easier for material 200 to enter the space between the guide parts 30 of the two grippers 20. As material 200 approaches the gripping space 34, the distance between the guide parts 30 of the two grippers 20 decreases, narrowing the space between the guide parts 30 of the two grippers 20. This allows material 200 to be gradually guided into the gripping space 34, so that a portion of material 200 enters the groove 24, and the other portion is located between the gripping parts 32 of the two grippers 20. Figure 3 and Figure 9 As shown.

[0034] Optionally, the gripping part 32 and the guide part 30 are connected as an integral structure.

[0035] In some implementations, please refer to Figures 3 to 6 The groove 24 has an anti-slip structure 36 on the side facing the other gripper 20.

[0036] This increases the friction between the clamping part 18 and the material 200, and to a certain extent prevents the material 200 from slipping and falling.

[0037] Specifically, when the gripper 18 grips the material 200, the anti-slip structure 36 comes into contact with the material 200. The anti-slip structure 36 can increase the friction between the side of the groove 24 and the material 200, thereby increasing the friction between the gripper 18 and the material 200, and to a certain extent preventing the material 200 held by the gripper 18 from slipping and falling off.

[0038] In some implementations, please refer to Figures 4 to 6 The anti-slip structure 36 includes multiple anti-slip points 40, which are arranged at intervals.

[0039] Therefore, the anti-slip structure 36 is easy to manufacture.

[0040] Specifically, the spaced arrangement of multiple anti-slip points 40 ensures a uniform distribution of the contact surface between the anti-slip structure 36 and the material 200, which helps to evenly increase friction. Optionally, the multiple anti-slip points 40 are arranged in an array on the side of the groove 24. In one embodiment, the anti-slip points 40 and the gripper 20 are integrated into a single structure.

[0041] In some implementations, please refer to Figures 3 to 5The gripper 18 includes two support blocks 42, each support block 42 is connected to a corresponding gripper 20. The support block 42 includes a support surface 44 and a contoured fitting surface 46. The support surface 44 is connected to the contoured fitting surface 46. The contoured fitting surface 46 is used to fit with the turning end of the conveyor belt 302 of the production line 300. The support surface 44 is used to limit the material 200 located in the groove 24 to prevent the material 200 from falling.

[0042] Therefore, on the one hand, the support block 42 can be better fitted to the production line 300, and on the other hand, the material 200 can be limited to further prevent the material 200 from falling.

[0043] Specifically, the contoured contact surface 46 is designed to mimic the shape of the turning end of the conveyor belt 302 of the production line 300, allowing the gripper 18 to be positioned as close as possible to the conveyor belt 302 of the production line 300. Specifically, when the gripper 18 is located on the first side of the flipping module 14, the contoured contact surface 46 is in contact with the turning end of the conveyor belt 302 of the production line 300, thereby allowing the gripper 18 to be closer to the conveyor belt 302 of the production line 300, further preventing the material 200 from falling off.

[0044] When the material 200 is clamped in the groove 24, the supporting surface 44 can be located below the material 200 to limit the material 200 and prevent it from falling. Optionally, the bottom surface of the groove 24 is flush with the supporting surface 44, or the supporting surface 44 is slightly lower than the bottom surface of the groove 24, so that the groove 24 can cover the side of the material 200.

[0045] In some implementations, please refer to Figures 2 to 3 The gripping and flipping mechanism 100 includes a positioning platform 48 located on the second side of the flipping module 14. The positioning platform 48 is used to carry and position the material 200 flipped to the second side of the flipping module 14. The gripping drive mechanism 16 is also used to drive the two grippers 20 to move away from each other to release the material 200 after the material 200 is flipped to the second side of the flipping module 14.

[0046] Therefore, after flipping the material 200, the material 200 can be placed on the positioning platform 48, which facilitates subsequent processing at the work station.

[0047] Specifically, please combine Figures 7 to 12The positioning platform 48 is located on the second side of the flipping module 14. After the flipping module 14 flips the gripping module 12 and the material 200 from the first side of the flipping module 14 to the second side of the flipping module 14, the material 200 can be just placed on the positioning platform 48, so that the positioning platform 48 can hold and position the material 200. Then, the gripping drive mechanism 16 can drive the two grippers 20 to move away from each other to release the material 200, so that the material 200 is separated from the grippers 20. The positioning platform 48 with the material 200 can be transferred to other processing equipment for processing, or processed in place by other processing equipment.

[0048] After the material 200 is released, the flipping module 14 can drive the unloaded gripping module 12 to flip from the second side of the flipping module 14 to the first side of the flipping module 14, so that the gripping module 12 can grip the next material 200.

[0049] In some implementations, please refer to Figure 3 The positioning platform 48 includes a placement plate 50 and multiple positioning blocks 52. The positioning blocks 52 are located on the placement plate 50. The multiple positioning blocks 52 and the placement plate 50 together form a positioning space 54. The positioning space 54 is used to position the material 200 on the second side of the flipping module 14.

[0050] Therefore, the material 200 can be effectively positioned by the cooperation of the placement plate 50 and the positioning block 52.

[0051] Specifically, to facilitate the entry of material 200 into the next workstation for processing, after material 200 is flipped, it needs to be effectively positioned to prevent displacement of material 200 and subsequent degradation of processing quality. After material 200 is flipped from the first side of the flipping module 14 to the second side of the flipping module 14, it is positioned in the positioning space 54 of the positioning platform 48. Thus, during the transfer of material 200 to the next workstation or during on-site processing at the next workstation, it can be ensured that material 200 and positioning platform 48 remain relatively stationary, while also preventing material 200 from falling.

[0052] exist Figure 3 In the middle, multiple positioning blocks 52 are located on the upper half of the placement plate 50 away from the flipping module 14, and the multiple positioning blocks 52 are respectively located close to the two sides and the top side of the placement plate 50, so that the positioning space 54 can position the material 200 on the three outer surfaces of the material 200.

[0053] In some implementations, please refer to Figure 3The clamping and flipping mechanism 100 includes a base plate 56, on which a first support block 58 and a second support block 60 are provided. The flipping module 14 includes a flipping drive mechanism 62, which includes a rotating shaft 64. The placement plate 50 is placed on the base plate 56 via the first support block 58. The rotating shaft 64 is fixedly connected to the clamping drive mechanism 16 and rotatably connected to the second support block 60.

[0054] This makes it easy to install the clamping module 12 and the placement plate 50.

[0055] Specifically, in Figure 3 In this design, the gripping component 18 is mounted on the gripping drive mechanism 16, which is fixedly connected to the rotating shaft 64 via a bracket 66. The end of the rotating shaft 64 passes through and is rotatably connected to the second support block 60. The second support block 60 provides another fulcrum at the end of the rotating shaft 64. When the rotating shaft 64 rotates, it can drive the gripping module 12 to flip between the first and second sides of the flipping module 14, thereby flipping the material 200 from the first side to the second side of the flipping module 14, and flipping the unloaded gripping module 12 from the second side to the first side of the flipping module 14 for gripping the next material 200. The structure is simple and easy to implement. The gripping drive mechanism 16 includes, but is not limited to, a cylinder.

[0056] The placement plate 50 is mounted on the base plate 56 via the first support block 58, which makes the positioning platform 48 relatively stable. The placement plate 50 and the first support block 58 can be connected by means of, but not limited to, bolts, clips, etc.

[0057] In some implementations, please refer to Figure 3 The flipping module 14 also includes a fixing plate 68, and the flipping drive mechanism 62 includes a drive body 70, which is connected to the rotating shaft 64. The drive body 70 is mounted on the base plate 56 via the fixing plate 68.

[0058] This facilitates the handling and installation of the clamping and flipping mechanism 100.

[0059] Specifically, the drive body 70 of the flipping drive mechanism 62 is mounted on the base plate 56 via a fixing plate 68. Thus, the base plate 56 can connect the positioning platform 48, the flipping module 14, and the clamping module 12 into a single unit, facilitating the handling and installation of the clamping and flipping mechanism 100. The drive body 70 can drive the rotating shaft 64 to rotate.

[0060] The connection methods between the components may include, but are not limited to, bolts, screws, welding, clips, etc.

[0061] The drive body 70 includes, but is not limited to, electrical components such as rotary motors and rotary cylinders that can achieve rotation.

[0062] Please combine Figure 1 and Figure 2 The production line 1000 provided by this utility model includes the gripping and flipping mechanism 100 of any of the above embodiments.

[0063] The aforementioned production line 1000 provides a groove 24 on the gripping surface of the gripper 20, ensuring that the material 200 remains clamped during the material handling and turning process. This eliminates defects caused by material dropping and also avoids safety hazards and human factors associated with manual material handling to a certain extent.

[0064] Optionally, the production line 1000 may further include a first processing device and a second processing device, the first processing device being connected to the gripping and flipping mechanism 100 via an assembly line 300. The assembly line 300 is located on the first side of the flipping module 14, and the second processing device is located on the second side of the flipping module 14. Optionally, the second processing device may also be connected to the gripping and flipping mechanism 100 via another assembly line 300.

[0065] When production line 1000 is operating, the first processing equipment processes material 200. After processing, the first processing equipment transfers the processed material 200 to assembly line 300. At this time, the first side 26 of material 200 faces upward and the second side 28 faces downward. Assembly line 300 transfers material 200 between the two grippers 20 of gripper 18. Gripping drive mechanism 16 drives the two grippers 20 to move closer together to grip material 200. Then, flipping module 14 drives gripping module 12 to flip material 200 from the first side of flipping module 14 to the second side, so that the second side 28 of material 200 faces upward and the first side 26 faces downward. The flipped material 200 is placed on positioning platform 48. Then, gripping drive mechanism 16 drives the two grippers 20 to move away from each other to release material 200. Flipping module 14 drives the unloaded gripping module 12 to flip from the second side of flipping module 14 to the first side to grip the next material 200. The material 200 located on the positioning platform 48 can be processed in place by the second processing equipment, or transferred to the second processing equipment via another production line 300 for processing. The first processing equipment includes, but is not limited to, a forging press, and the second processing equipment includes, but is not limited to, a forming machine.

[0066] Optionally, in Figure 2 In the production line 1000, a support frame 72 is also included, and the clamping and flipping mechanism 100 can be mounted on the support frame 72 via the base plate 56.

[0067] In summary, the clamping and flipping mechanism 100 and production line 1000 of this utility model are highly functional, simple in structure, and can be integrated into automation to avoid external factors. The mechanism meets the need to replace manual labor. The clamping and flipping mechanism 100 has properties such as high temperature resistance, anti-fall-off, and material flipping function.
