[0079] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0080] See also Figure 1 The embodiment of the present application provides a flipping device 100, which includes a clamping assembly 10, a driving assembly 20 disposed on one side of the clamping assembly 10, a flipping assembly 30 connected to the clamping assembly 10, and a holding assembly 40 disposed on the side of the driving assembly 20 away from the clamping assembly 10. The flipping device 100 realizes mechanical and standardized flipping of the workpiece, without manual flipping of the workpiece, thereby improving flipping efficiency and flipping accuracy. The workpiece may be a mobile phone middle frame, a mobile phone middle plate, etc.

[0081] For ease of description, a three-dimensional coordinate system is established in some drawings. Specifically, the X-axis direction is the second direction, the Y-axis direction is the first direction, and the Z-axis direction is the third direction, wherein the X-axis direction, the Y-axis direction, and the Z-axis direction are perpendicular to each other.

[0082] See also Figure 2 The clamping assembly 10 includes a clamping drive 11 rotatably connected to the driving assembly 20, and two clamping members 12 connected to the clamping drive 11 and symmetrically arranged at opposite ends of the clamping drive 11. The clamping drive 11 is connected to the flip assembly 30, and the two clamping members 12 are both roughly plate-shaped structures, and the two clamping members 12 are arranged opposite to each other and are respectively connected to the clamping drive 11. Exemplarily, in this embodiment, the clamping drive 11 is a cylinder.

[0083] In this way, the clamping drive member 11 drives the two clamping members 12 to move toward each other to clamp the workpiece, or move away from each other to release the workpiece, thereby achieving mechanized clamping or loosening of the workpiece without manual clamping of the workpiece, thereby improving the clamping efficiency and stability.

[0084] Please continue reading Figure 2The clamping member 12 includes a movable body 121 connected to the clamping driving member 11, and a flexible clamping body 122 connected to the movable body 121. The movable body 121 is generally a plate-shaped structure, and the movable body 121 is connected to the clamping driving member 11. The flexible clamping body 122 is generally a block-shaped structure, and the flexible clamping body 122 is arranged on a side of the movable body 121 facing the other clamping member 12. Exemplarily, the material of the flexible clamping body 122 is eutectic.

[0085] In this way, the movable body 121 drives the flexible clamping body 122 to move close to the workpiece, so that the flexible clamping body 122 can flexibly clamp the workpiece, avoiding excessive clamping force applied to the workpiece by the clamping member 12 and causing damage to the workpiece, thereby improving the clamping stability of the clamping assembly 10 and the quality of the workpiece.

[0086] See also Figure 1 , Figure 3 and Figure 4 The driving assembly 20 includes a lifting driving member 21 arranged on one side of the clamping driving member 11, a moving member 22 connected to the lifting driving member 21, a fixing member 23 connected to the moving member 22, two limiting members 24 arranged at intervals on the moving member 22, and a guide member 25 arranged on one side of the moving member 22. The lifting drive member 21 is arranged at one side of the clamping drive member 11 along the Y-axis direction, the moving member 22 is roughly in a plate-like structure, the moving member 22 is connected to the lifting drive member 21, and the moving member 22 moves along the Z-axis direction under the drive of the lifting drive member 21, the fixed member 23 is roughly in a rod-like structure, the fixed member 23 is connected to the side of the moving member 22 away from the clamping assembly 10, the two limit members 24 are roughly in a rod-like structure, the two limit members 24 are arranged at intervals along the Z-axis direction on the side of the moving member 22 away from the clamping assembly 10 and are both connected to the moving member 22, the two limit members 24 are away from the lifting drive member 21 relative to the fixed member 23 along the Z-axis direction, the guide member 25 is roughly in a long plate-like structure, the guide member 25 is arranged at one side of the moving member 22 along the X-axis direction, and the guide member 25 is provided with a guide groove 251 on the side facing the moving member 22, and the guide groove 251 is extended along the Z-axis direction and accommodates part of the moving member 22. Exemplarily, the lifting drive member 21 is a cylinder.

[0087] In this way, when the lifting drive member 21 drives the moving member 22 to move along the Z-axis direction, the moving member 22 is guided by the guide member 25 that accommodates part of the moving member 22, so that the moving member 22 always moves stably along the Z-axis direction, thereby improving the movement stability of the moving member 22.

[0088] See 3 and Figure 4 The flip assembly 30 includes an elastic member 31 connected to the fixing member 23 and a flip member 32 connected to the elastic member 31. The flip member 32 passes through the moving member 22 and is connected to the clamping driving member 11, and the two ends of the elastic member 31 are respectively connected to the flip member 32 and the fixing member 23. Exemplarily, the elastic member 31 is a spring.

[0089] In this way, the flipping member 32 is connected to the clamping driving member 11, so that the flipping member 32 can drive the workpiece clamped by the clamping member 12 to flip synchronously, thereby quickly flipping the workpiece to a preset orientation, thereby improving the flipping efficiency.

[0090] See also Figure 4 The flip member 32 includes a rotating shaft 321 connected to the clamping driving member 11, a connecting body 322 connected to the rotating shaft 321, and a rotating body 323 connected to the connecting body 322. The rotating shaft 321 is generally a rod-shaped structure, and the rotating shaft 321 is movably arranged in the moving member 22 along the Y-axis direction and connected to the clamping driving member 11. The two ends of the connecting body 322 are respectively connected to the rotating shaft 321 and the other end of the elastic member 31. The connecting body 322 and the fixing member 23 are located on both sides of the limiting member 24 along the Z-axis direction. The rotating body 323 is arranged on the side of the connecting body 322 away from the clamping driving member 11 and connected to the connecting body 322.

[0091] In this way, when the workpiece is flipped to a preset orientation, the rotating body 323 is first abutted against the abutting assembly 40 under the drive of the moving member 22, so that the connecting body 322 rotates along the preset direction and stretches the elastic member 31, and then the rotating body 323 is disengaged from the abutting assembly 40 under the drive of the moving member 22, so that the stretched elastic member 31 provides elastic force to drive the connecting body 322 to continue to rotate along the preset direction, so that the connecting body 322 drives the workpiece clamped by the clamping member 12 to flip to the preset orientation through the rotating shaft 321, and at the same time, the connecting body 322 abuts against the limiting member 24, so that the connecting body 322 and the limiting member 24 cooperate with the workpiece clamped by the limiting clamping member 12, so that the workpiece maintains the preset orientation, prevents the workpiece from continuing to rotate and deviate from the preset orientation, and improves the flipping accuracy and stability.

[0092] See also Figure 3 and Figure 4 The connecting body 322 includes a connecting portion 3221 connected to the rotating shaft 321 and a protruding portion 3222 connected to the connecting portion 3221. The connecting portion 3221 is generally in the shape of a long strip, and is connected to one end of the rotating shaft 321 away from the clamping driving member 11. The rotating body 323 is disposed on a side of the connecting portion 3221 away from the rotating shaft 321 and is connected to the connecting portion 3221. The protruding portion 3222 is generally in the shape of a cylindrical rod, and is disposed on one end of the connecting portion 3221 away from the rotating shaft 321 and is connected to the elastic member 31.

[0093] In this way, when the rotating body 323 abuts against the abutting assembly 40, the connecting portion 3221 rotates with the rotating shaft 321 as the center and drives the protrusion 3222 to rotate synchronously, so that the protrusion 3222 stretches the elastic member 31. When the rotating body 323 disengages from the abutting assembly 40, the stretched elastic member 31 drives the connecting portion 3221 through the protrusion 3222 to drive the workpiece clamped by the clamping member 12 to rotate synchronously, thereby flipping the workpiece to a preset direction.

[0094] See also Figure 4 The rotating body 323 includes two rotating parts 3231 connected to the connecting part 3221 . The two rotating parts 3231 are symmetrically arranged about the axial direction of the connecting part 3221 and are both inclined to the axial direction of the connecting part 3221 . The two rotating parts 3231 are both connected to the connecting part 3221 .

[0095] The rotating part 3231 includes a linkage block 3231a connected to the connecting part 3221 and a rotating body 3231b connected to the linkage block 3231a. The linkage block 3231a is generally in the shape of a long strip, and the linkage block 3231a is arranged obliquely relative to the axial direction of the connecting part 3221 and connected to the connecting part 3221. The rotating body 3231b is generally in the shape of a rod, and the rotating body 3231b is arranged at one end of the linkage block 3231a away from the connecting part 3221 and connected to the side of the linkage block 3231a away from the connecting part 3221.

[0096] Please continue reading Figure 3 and Figure 4 The length of the limit member 24 in the Y-axis direction is greater than the distance between the connecting portion 3221 and the movable member 22, and is smaller than the distance between the linkage block 3231a and the movable member 22. This enables the clearance between the linkage block 3231a and the limit member 24 to be matched during the rotation of the flip member 32, thereby preventing interference between the linkage block 3231a and the limit member 24 that causes the flip member 32 to be unable to rotate to a preset angle. At the same time, it ensures that the connecting portion 3221 abuts against the limit member 24 after the workpiece is flipped, which is beneficial to the normal flipping operation of the flip member 32.

[0097] See also Figure 1 and Figure 5 The abutting assembly 40 includes a base 41 disposed on the side of the lifting drive member 21 away from the clamping drive member 11, a sliding member 42 slidably connected to the base 41, and an abutting member 43 connected to the sliding member 42. The base 41 is generally a long plate-shaped structure, and the base 41 is adjacent to the side of the lifting drive member 21 away from the clamping drive member 11 and is provided with a sliding groove 411, which extends along the Z-axis direction and accommodates part of the sliding member 42, and the abutting member 43 is disposed on the side of the sliding member 42 away from the base 41.

[0098] In this way, when the moving member 22 moves in a direction away from the sliding member 42 , the abutting member 43 can abut against the rotating body 323 , so that the connecting body 322 rotates around the rotating shaft 321 , thereby realizing the turning operation of the workpiece.

[0099] See also Figure 5 The sliding member 42 includes a sliding body 421 slidably disposed on the base 41, and a conical body 422 connected to the sliding body 421. The sliding body 421 is generally in the shape of a long plate, and the sliding body 421 is slidably connected to the base 41. The abutting member 43 is disposed on the sliding body 421 and connected to the sliding body 421. The conical body 422 is generally in the shape of a triangular pyramid, and the conical body 422 is connected to the sliding body 421. The conical body 422 is provided with a receiving groove 4221 and two abutting inclined surfaces 4222. The receiving groove 4221 is disposed on the side of the conical body 422 away from the sliding body 421 and is clearance-matched with the fixing member 23. The two abutting inclined surfaces 4222 are symmetrically disposed on both sides of the receiving groove 4221 along the X-axis direction and are inclined relative to the X-axis direction.

[0100] The supporting member 43 includes two supporting bodies 431 connected to the sliding body 421. The two supporting bodies 431 are located on both sides of the conical body 422 along the X-axis direction and are both connected to the side of the sliding body 421 away from the base 41. The ends of the two supporting bodies 431 away from the sliding body 421 form an activity space 4311.

[0101] First, one of the rotating parts 3231 moves close to the corresponding abutting body 431 under the drive of the moving part 22 and abuts against the corresponding abutting body 431, so that the connecting body 322 can drive the other rotating part 3231 to rotate into the activity space 4311 with the rotating shaft 321 as the center, and at the same time, the connecting body 322 stretches the elastic member 31 connected to it, and then, the rotating part 3231 abutting against the abutting body 431 is separated from the abutting body 431 under the drive of the moving part 22, and the stretched elastic member 31 provides elastic force and drives the connecting body 322 to drive the clamped workpiece to rotate synchronously, so as to flip the workpiece to a preset direction, and at the same time, the connecting body 322 abuts against the limiting member 24 to limit the workpiece, and finally, the rotating part 3231 is separated from the abutting body 431. Driven by the movable part 22, the rotating part 3231 continues to move close to the cone 422, and pushes the cone 422 through the corresponding abutment slope 4222 to drive the sliding body 421 to move along the X-axis direction, so that the other rotating part 3231 is misaligned with the active space 4311 and corresponds to the other abutment body 431, so that the other rotating part 3231 abuts against the other abutment body 431 when the flipping operation is repeated, thereby ensuring that the flipping device 100 repeats the flipping operation of the workpiece. At the same time, the storage groove 4221 stores the fixed part 23 and cooperates with the fixed part 23 when the movable part 22 moves close to the cone 422, so as to avoid the fixed part 23 interfering with the movement of the cone 422 along the X-axis direction.

[0102] The abutting body 431 includes a supporting portion 4312 connected to the sliding body 421 and an abutting portion 4313 connected to the supporting portion 4312. The supporting portion 4312 is generally a rod-shaped structure, and the supporting portion 4312 is extended along the Z-axis direction and arranged on the sliding body 421, and the abutting portion 4313 is generally a rod-shaped structure, and the abutting portion 4313 is protruded along the X-axis direction on one side of the supporting portion 4312 facing the other abutting body 431.

[0103] In this way, by setting the specific structure of the supporting body 431, a accommodating space can be formed between the supporting part 4312, the supporting part 4313 and the sliding body 421, so that the movable part 22 can drive the flipping part 32 to move in the accommodating space, and when the rotating body 3231b of the rotating part 3231 moves a preset distance, it can stably abut against the corresponding supporting part 4313 to stably realize the flipping operation of the workpiece.

[0104] The working process of the above-mentioned flipping device 100 is roughly as follows:

[0105] First, the clamping driving member 11 drives the two clamping members 12 to move toward each other to clamp the workpiece, and the workpiece is in the initial orientation at this time;

[0106] Secondly, the lifting driving member 21 drives the moving member 22 to move away from the sliding body 421, and one of the rotating parts 3231 abuts against the corresponding abutting body 431, so that the connecting body 322 drives the other rotating part 3231 to rotate into the activity space 4311 with the rotating shaft 321 as the center, and at the same time, the connecting body 322 stretches the elastic member 31 connected thereto;

[0107] Then, the lifting driving member 21 drives the moving member 22 to move close to the sliding body 421, and the rotating part 3231 abutting against the abutting body 431 is separated from the abutting body 431 under the drive of the moving member 22, and the stretched elastic member 31 provides elastic force and drives the connecting body 322 to drive the clamped workpiece to rotate synchronously, and the connecting body 322 abuts against the limiting member 24 when the workpiece is flipped to the preset direction to limit the continued rotation of the flipped workpiece, so that the workpiece clamped by the clamping member 12 can be quickly and accurately flipped to the preset direction, thereby improving the flipping efficiency and accuracy;

[0108] Finally, after the workpiece is flipped to the preset orientation, the lifting drive member 21 drives the moving member 22 to continue to move closer to the sliding body 421, and the rotating portion 3231 that is separated from the supporting body 431 pushes the conical body 422 through the corresponding abutment slope 4222 to drive the sliding body 421 to move along the X-axis direction, so that the other rotating portion 3231 is misaligned with the active space 4311 and corresponds to the other supporting body 431, so that the other rotating portion 3231 is abutted against the other supporting body 431 when the flipping operation is repeated, thereby ensuring that the flipping device 100 repeats the flipping operation of the workpiece. At the same time, the storage groove 4221 receives the fixed member 23 when the moving member 22 moves close to the conical body 422 and cooperates with the fixed member 23 clearance, so as to prevent the fixed member 23 from interfering with the movement of the conical body 422 along the X-axis direction.

[0109] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present application and are not intended to limit it. Although the present application has been described in detail with reference to the preferred embodiments, a person of ordinary skill in the art should understand that the technical solution of the present application may be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the present application.
