Detailed Implementation

[0043] To make the objectives, technical solutions, and advantages of this disclosure clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0044] Flipping plays an important role in industrial production. In the production process of various industries, it is often necessary to flip objects from one direction to another (e.g., 180° flip) according to the production process requirements of the product in order to carry out the next operation (e.g., processing, inspection, assembly, etc.) and thus enable the entire process to proceed continuously.

[0045] To achieve the purpose of material flipping, related technologies typically employ manual flipping or robotic arms to clamp and flip the material.

[0046] Each time a material is flipped, the operator or robotic arm can usually only flip one material, resulting in low efficiency and long processing time for the flipping process.

[0047] Reference Figure 1 As shown in the figure, this disclosure provides a material flipping mechanism, which may include a conveying component 1, a lifting component 2, and a clamping and rotating component 3.

[0048] The conveying assembly 1 is used for conveying the material to be turned over, and the jacking assembly 2 is located below the material to be turned over and is used for jacking up the material to be turned over.

[0049] Referring to Figure 2 As shown in the figure, the clamping and rotating assembly 3 includes a driving clamping arm 31, a driven clamping arm 32, and a clamping driving member 33. The driving clamping arm 31 includes a plurality of first clamping blocks 311, a plurality of rotating driving members 312, and a first clamping arm body 313. The first clamping blocks 311 are connected to the rotating driving members 312 one by one. The plurality of rotating driving members 312 are connected to the first clamping arm body 313. The driven clamping arm 32 includes at least two second clamping blocks 321 and a second clamping arm body 322. The second clamping blocks 321 correspond to the first clamping blocks 311 one by one and are rotationally connected to the second clamping arm body 322. The clamping driving member 33 is in transmission connection with the first clamping arm body 313 and the second clamping arm body 322, respectively.

[0050] In the embodiments of the present disclosure, the clamping and rotating assembly 3 has a plurality of first clamping blocks 311 and a plurality of second clamping blocks 321, so that a plurality of materials to be turned over can be clamped at the same time. In this way, the material turning mechanism can turn over a plurality of materials to be turned over at the same time in one turning action, reduces the working time of the turning process, and improves the working efficiency of the turning process.

[0051] The present disclosure does not limit the specific type of the material to be turned over, which can be matched and set according to the use scene of the material turning mechanism. For example, the material to be turned over can be a metal part or an electronic device.

[0052] In some embodiments, the contact surfaces of the first clamping blocks 311 and the second clamping blocks 321 with the material to be turned over can be provided with a buffer layer made of a flexible material such as sponge, so that the friction between the first clamping blocks 311, the second clamping blocks 321 and the material to be turned over does not cause damage to the material to be turned over during the turning process.

[0053] In some embodiments, as shown in the figure, Figure 3 The clamping driving member 33 can include a support plate 331 and an electric claw 332. The electric claw 332 is connected to the support plate 331 and has two movable ends 332a connected to the first clamping arm body 313 and the second clamping arm body 322, respectively.

[0054] The electric claw 332 is a mechanical claw based on the principle of an electromagnet, which has the characteristics of high precision and good stability. The electric claw 332 is internally integrated with a motor (e.g., a servo motor), a transmission mechanism, two movable ends 332a, and a control system, and has multiple working modes such as speed, torque, and position.

[0055] In this embodiment, the electric gripper 332 can be controlled in parallel using displacement mode and torque mode, thereby ensuring that the clamping force between the first clamping block 311 and the second clamping block 321 can be monitored and adjusted in real time. On the one hand, the displacement mode can automatically adjust the clamping position according to the size parameters of different materials to be flipped. On the other hand, the torque mode can identify whether the material to be flipped has been successfully clamped and the target clamping force has been reached. This can both ensure the clamping of the material to be flipped by the first clamping block 311 and the second clamping block 321 and avoid the problem of material damage caused by excessive clamping force.

[0056] Among them, the three types of material damage refer to the damage to the appearance of materials caused by various reasons during the production, handling, storage or processing of materials, such as: bumps, scratches and pressure marks.

[0057] In some embodiments, refer to Figure 4 As shown, the clamping drive component 33 may include a support plate 331, two nuts 333, a lead screw 334, and a motor 335. The two nuts 333 are respectively connected to the first clamping arm body 313 and the second clamping arm body 322. The lead screw 334 is driven by the two nuts 333. The thread direction of the lead screw 334 is opposite to that of different areas of the two nuts 333. The motor 335 is driven by the lead screw 334 and is used to drive the lead screw 334 to rotate.

[0058] Motor 335 drives lead screw 334 to rotate. Lead screw 334 is fixed in the axial direction and slides relative to the two nuts 333, thereby driving the two nuts 333 to move linearly along the axial direction of lead screw 334. At the same time, the thread directions of different areas of lead screw 334 corresponding to the two nuts 333 are opposite, so the two nuts 333 move towards each other or in opposite directions, thereby realizing the first clamping arm body 313 and the second clamping arm body 322, which are respectively connected to the two nuts 333, to move towards each other (i.e., clamping process) or in opposite directions (i.e., releasing process).

[0059] In some embodiments, refer to Figure 5 As shown, the conveying assembly 1 includes a baffle 11, multiple support legs 12, two parallel conveyor belts 13, and a material substrate 14.

[0060] The baffle 11 is connected to the support foot 12 and slidably connected to the conveyor belt 13. On the one hand, the baffle 11 provides an installation position for the conveyor belt 13. On the other hand, the baffle 11 is located between the external environment of the material turning mechanism and the conveyor belt 13, which can effectively prevent foreign objects or operators from entering the working area of ​​the conveyor belt 13. This can ensure the stable operation of the conveyor belt 13 and also prevent operators from accidentally touching the working conveyor belt 13 and causing personal injury.

[0061] The connection relationship between the baffle 11 and the supporting leg 12 is not specifically limited in the present disclosure, and can adopt a detachable connection mode such as threaded fastening connection, buckle connection, or a non-detachable connection mode such as glue dispensing or welding. The specific connection mode can be matched and set according to the use scene of the material overturning mechanism, the connection strength requirement of the baffle 11 and the supporting leg 12 of different material overturning mechanisms, and other factors.

[0062] The plurality of supporting legs 12 are used to fix and support the material overturning mechanism. The supporting leg 12 can be connected with the ground or other foundation platform, thereby realizing the fixation of the entire material overturning mechanism.

[0063] The space between the two conveying belts 13 is used to accommodate the jacking assembly 2. In this way, the clamping and rotating assembly 3 is located above the conveying assembly 1, and the jacking assembly 2 is located inside the conveying assembly 1. The overall volume of the material overturning mechanism is small, which is conducive to the use of the material overturning mechanism in narrow places, and is also conducive to the assembly and transportation of the material overturning mechanism.

[0064] The two ends of the material base plate 14 are respectively overlapped with the two conveying belts 13, and the material base plate 14 is used to accommodate the material to be overturned. The arrangement of the material base plate 14 avoids the direct contact between the material to be overturned and the conveying belt 13, and effectively avoids the material damage problem caused by the vibration of the conveying assembly 1 and the friction of the conveying belt 13.

[0065] In some embodiments, as shown in Figure 1 , Figure 4 and Figure 5 , the supporting plate 331 is connected with the baffle 11 in the conveying assembly 1. Since the clamping and rotating assembly 3 is located above the conveying assembly 1, compared with being directly connected with the ground and the foundation platform, the supporting plate 331 is connected with the baffle 11, which can reduce the raw material usage and weight of the supporting plate 331, thereby reducing the manufacturing cost of the material overturning mechanism.

[0066] In some embodiments, as shown in Figure 6 , the material base plate 14 has a plurality of movable clamping jaws 141, and the size of the area defined by the plurality of movable clamping jaws 141 is adapted to the size of the material to be overturned. The movable clamping jaw 141 can adjust the position within a certain range. In this way, for different sizes of the material to be overturned, the material base plate 14 can adjust the position of the movable clamping jaw 141, so that the size of the area defined by the movable clamping jaw 141 is adapted to the size of various materials to be overturned, thereby improving the compatibility of the material base plate 14.

[0067] The number of movable clamping jaws 141 is not specifically limited in the present disclosure, and can be matched and set according to the size of the material base plate 14, the size and shape of the material to be overturned, the clamping strength requirement of the movable clamping jaw 141 and the material to be overturned, and other parameters.

[0068] The adjustment mode of the movable clamping jaw 141 is not specifically limited in the present disclosure. For example, the movable clamping jaw 141 can be manually adjusted by a person. For another example, the movable clamping jaw 141 can be driven by a pneumatic cylinder or a hydraulic cylinder to adjust. The adjustment accuracy requirement and the manufacturing cost limitation of the material substrate 14 can be matched and set.

[0069] In some embodiments, referring to Figure 5 and Figure 6 The conveying assembly 1 further includes a blocking piece 15 located between the two conveying belts 13. The blocking piece 15 is used to abut against the material substrate 14 to determine the target working position of the material to be turned over on the jacking assembly 2. The blocking piece 15 can be set with a working period according to the conveying speed of the conveying belt 13 and other factors, and lifted at a specific time in each working period. In this way, the material substrate 14 abuts against the blocking piece 15, thereby ensuring that the material substrate 14 and the material to be turned over stop at the target working position of the jacking assembly 2, and avoiding a certain misalignment of the material substrate 14 and the material to be turned over due to inertia, vibration and other factors.

[0070] In some embodiments, referring to Figure 6 The conveying assembly 1 further includes a supporting plate 16 located in the area surrounded by the conveying belt 13 and connected to the baffle 11. The supporting plate 16 is used to provide a supporting force to the conveying belt 13 and the material substrate and the material to be turned over carried by the conveying belt 13, thereby ensuring the stable conveying of the material substrate 14 and the material to be turned over on the conveying belt 13.

[0071] The supporting plate 16 can also prevent the conveying belt 13 from sagging at some positions, effectively reducing the direct contact of the conveying belt 13 with the ground or other objects, thereby reducing the wear of the conveying belt 13 and avoiding potential conveying risks caused by the sagging conveying belt 13.

[0072] In some embodiments, referring to Figure 7 The rotary driving member 312 includes a rotary cylinder 3121, a first rotary bearing 3122, an inductive sheet 3123 and at least two photoelectric sensors 3124. The rotary cylinder 3121 is in transmission connection with the first rotary bearing 3122. The first rotary bearing 3122 is connected with the first clamping block 311 and the inductive sheet 3123, respectively. The photoelectric sensors 3124 are used to detect the position of the inductive sheet 3123.

[0073] The rotary cylinder 3121 can drive the first rotary bearing 3122 to rotate the first clamping block 311 and the sensing plate 3123. Taking a flipping angle of 180° as an example, when the first clamping block 311 is in the first position, the sensing plate 3123 is opposite to a photoelectric sensor 3124. After the rotary cylinder 3121 drives the first rotary bearing 3122 to rotate the first clamping block 311 and the sensing plate 3123 by 180°, the sensing plate 3123 is opposite to another photoelectric sensor 3124. In this way, the rotation attitude of the first rotary bearing 3122 can be detected in real time by detecting the position of the sensing plate 3123 through the photoelectric sensor 3124, thereby ensuring the attitude of the first clamping block 311 and the material to be flipped, and ensuring that the material to be flipped can be flipped into place.

[0074] In some embodiments, refer to Figure 3 and Figure 4 As shown, the driven clamping arm 32 also includes a second rotary bearing 323, which is connected to the second clamping arm body 322 and the second clamping block 321 respectively. The second rotary bearing 323 can reduce the friction between the second clamping arm body 322 and the second clamping block 321. On the one hand, it can improve the working life of the driven clamping arm 32; on the other hand, it can reduce the increased power consumption of the active clamping arm 31 due to overcoming the friction between the second clamping arm body 322 and the second clamping block 321.

[0075] In some embodiments, refer to Figure 8 As shown, the lifting component 2 includes a suction cup 21, which is located on the side of the lifting component 2 facing the material to be flipped, and is used to connect the lifting component 2 with the material to be flipped.

[0076] The suction cup 21 ensures that when the lifting component 2 lifts the material to be flipped, the lifting component 2 not only provides support but also provides suction through the suction cup 21. This ensures that the material to be flipped will not fall off the lifting component 2 due to factors such as vibration of the material flipping mechanism, thus protecting the material to be flipped and ensuring the working efficiency of the material flipping mechanism.

[0077] In some embodiments, the lifting component 2 is a single-stage lifting structure, that is, the lifting component 2 is connected to the suction cup of the material to be flipped through the suction cup 21, and the material to be flipped is lifted, while the material substrate 14 is not lifted by the lifting component 2.

[0078] In some other embodiments, the lifting component 2 is a two-stage lifting structure. Taking a 180° flipping angle as an example, its working process is as follows:

[0079] First, the main body of the lifting component 2 simultaneously lifts the material substrate 14 and the material to be flipped. At this time, the material substrate 14 gradually separates from the conveyor belt 13 until it is lifted to the first lifting position.

[0080] Then, the suction cup 21 is connected with the material to be flipped, and continues to lift the material to be flipped, at this time, the clamping between the material to be flipped and the movable clamping jaw 141 gradually fails until it is lifted to the second lifting position;

[0081] Then, the clamping and rotating assembly 3 flips the material to be flipped located in the second lifting position;

[0082] Then, the suction cup 21 is connected with the flipped material, and is lowered to the first lifting position, at this time, the flipped material and the movable clamping jaw 141 are clamped again;

[0083] Finally, the material substrate 14 and the flipped material can be transferred to other target positions by other ways.

[0084] The jacking assembly 2 is a two-stage lifting structure, which can realize the whole transfer of the material substrate 14 and the flipped material, or the respective transfer of the material substrate 14 and the flipped material, so as to realize the separation of the flipped material from the conveying assembly.
