[0036] After the clamping component 2 clamps the workpiece on the carrier 32 of the lifting and lowering bearing component 3, the lifting and lowering driving component 31 of the lifting and lowering bearing component 3 drives the carrier 32 away from the clamping component 2 to avoid the clamping component 2; after the rotating driving component 1 rotates the clamping component 2, the lifting and lowering driving component 31 of the lifting and lowering bearing component 3 drives the carrier 32 to approach the clamping component 2 to receive the workpiece on the clamping component 2.

[0039] The clamping assembly 2 may include a first driving member, a first clamping plate, and a second clamping plate. The first driving member is in transmission connection with the first clamping plate, and the first clamping plate and the second clamping plate are arranged opposite to each other. The first driving member drives the first clamping plate to move toward the second clamping plate to clamp the workpiece, and the first driving member drives the first clamping plate to move away from the second clamping plate to release the workpiece. The first driving member, the first clamping plate, and the second clamping plate may be mounted on a mounting plate, and the mounting plate is in transmission connection with the rotating driving member 11.

[0040] The clamping assembly 2 may also include a clamping drive, a first clamping plate and a second clamping plate, wherein the clamping drive is connected to the first clamping plate and the second clamping plate in a transmission manner to drive the first clamping plate and the second clamping plate to move closer to or further away from each other.

The mounting secondary part is provided with an adjustment hole connected to the adjustment screw, the movable secondary part is provided with a threaded hole threadedly connected to the adjustment screw, the adjustment screw is passed through the adjustment hole and threadedly connected to the threaded hole, and the distance between the movable secondary part and the reference secondary part can be adjusted by rotating the adjustment screw, so that the first clamping part can adapt to workpieces of different thicknesses. The second clamping plate can adopt the same structure as the first clamping plate.

[0041] The workpiece may be a battery, a battery cell or other processed parts. The embodiment of the present application is mainly used to flip the power battery after the top cover side welding is completed, and flip the power battery 180 degrees from the top cover downward to the top cover upward.

[0042] After the flipping device clamps the workpiece on the carrier 32 of the lifting and lowering bearing assembly 3 through the clamping assembly 2, the lifting drive component 31 of the lifting and lowering bearing assembly 3 drives the carrier 32 away from the clamping assembly 2 to avoid the clamping assembly 2, thereby preventing the rotating workpiece from interfering with the carrier 32, thereby reducing the loss rate of the workpiece; the rotating drive assembly 1 rotates the clamping assembly 2 to flip the workpiece; the lifting drive component 31 of the lifting and lowering bearing assembly 3 drives the carrier 32 to approach the clamping assembly 2 to promptly receive the workpiece, thereby preventing the clamping assembly 2 from clamping the workpiece for too long, thereby shortening the time that the rotating reduction component 12 is subjected to the eccentric torque force, thereby reducing the loss rate of the rotating reduction component 12.

[0043] The flipping device also includes a bracket 4 and a rotating shaft 5. Both ends of the rotating shaft 5 are rotatably mounted on the bracket 4. One end of the rotating shaft 5 is transmission-connected to the rotating driving member 11 via the rotating reduction member 12. The clamping assembly 2 is mounted on the rotating shaft 5.

[0044] Since the embodiment of the present application is mainly used for the power battery after the welding of the flip top cover side is completed, the volume and weight of this power battery are relatively large, and the driving shaft of the rotating driving member 11 is directly connected to the clamping assembly 2, and the driving shaft of the rotating driving member 11 is easy to break, and the rotating driving member 11 is easy to be damaged. The bracket 4 can reduce the load of the driving shaft of the rotating driving member 11, and can also reduce the eccentric torque force on the rotating reduction member 12, and reduce the loss rate of the rotating driving member 11 and the rotating reduction member 12.

[0045] The bracket 4 includes a base plate, a first support plate and a second support plate. The first support plate and the second support plate are relatively mounted on the base plate. The shaft 5 is rotatably mounted on the first support plate and the second support plate. The clamping assembly 2 is located between the first support plate and the second support plate.

[0046] There are two lifting and lowering bearing components 3, which are respectively arranged on both sides of the rotating shaft 5. The rotating driving member 11 drives the rotating shaft 5 to rotate so that the clamping component 2 is close to the lifting and lowering bearing component 3 located on one side of the rotating shaft 5. After the clamping component 2 clamps the workpiece on the lifting and lowering bearing component 3 located on one side of the rotating shaft 5, the rotating driving member 11 drives the rotating shaft 5 to rotate in the opposite direction so that the clamping component 2 is close to the lifting and lowering bearing component 3 located on the other side of the rotating shaft 5. The clamping component 2 places the workpiece on the lifting and lowering bearing component 3 located on the other side of the rotating shaft 5.

[0047] Since the clamping assembly 2 is arranged on the side wall of the rotating shaft 5, after the clamping assembly 2 flips the workpiece, the workpiece will move a certain distance in the horizontal direction. Two lifting and bearing assemblies 3 can be set to carry the workpiece before and after flipping respectively, further reducing the residence time of the workpiece on the clamping assembly 2, reducing the time that the rotating reduction component 12 is subjected to the eccentric torque force, and reducing the loss rate of the rotating reduction component 12.

[0048] The support 4 is provided with a position detection member 41 , and the position detection member 41 is used to detect whether there is a workpiece on the carrier 32 .

[0049] The in-place detection member 41 may be a photoelectric sensor or a 3D camera. The in-place detection member 41 is disposed on the bracket 4 but not mounted on the carrier 32, so as to prevent the connection line on the in-place detection member 41 from being pulled and moved to cause wear.

[0050] A limiting member 51 is provided on the side wall of the rotating shaft 5 , and an angle limiting member 5142 is provided on the bracket 4 . When the rotating driving member 11 rotates the rotating shaft 5 , the limiting member 51 on the rotating shaft 5 can abut against the angle limiting member 5142 to control the rotation angle of the rotating shaft 5 .

[0051] Since the embodiment of the present application is mainly used to flip the power battery after the top cover side welding is completed, the power battery is flipped 180 degrees from the top cover downward to the top cover upward. If the flip angle of the power battery is incorrect, the next process of the power battery will be affected, so the rotation angle of the rotating shaft 5 needs to be controlled.

[0052] The limit member 51 is a limit block arranged on the side wall of the rotating shaft 5. The angle limit member 5142 includes a limit mounting portion and a limit screw. The limit mounting portion is installed on the side wall of the first support plate or the second support plate of the bracket 4. The limit screw is threadedly connected to the threaded hole on the limit mounting portion. One end of the limit screw abuts against the limit member 51 to limit the rotation of the rotating shaft 5.

[0053] A wiring conduit 52 is disposed in the rotating shaft 5 . The inlet end of the wiring conduit 52 is disposed on the side wall of the rotating shaft 5 , and the outlet end of the wiring conduit 52 is disposed on the end of the rotating shaft 5 .

[0054] When the clamping assembly 2 clamps the workpiece and turns 180°, the rotation angle is large, and the air pipe or wire on the clamping assembly 2 may be entangled, cut or damaged. The air pipe or wire on the clamping assembly 2 enters from the inlet end of the wiring duct 52 and is led out from the outlet end of the wiring duct 52, so that the air pipe or wire of the clamping assembly 2 can rotate with the rotation of the rotating shaft 5, preventing the air pipe or wire from being entangled or damaged.

[0055] A wiring groove 53 is provided on the side wall of the rotating shaft 5 .

[0056] Before the air pipe or wire on the clamping component 2 enters the wiring pipe 52, there is a certain distance between the air pipe or wire on the clamping component 2 and the entrance end of the wiring pipe 52. The air pipe or wire on the clamping component 2 may fall and be scratched by other components when the rotating shaft 5 rotates. The wiring groove 53 can prevent the air pipe or wire on the clamping component 2 from falling before entering the entrance end of the wiring pipe 52.

[0057] The lifting drive member 31 is provided with a lifting platform 311, and a slot 3111 is provided on the lifting platform 311. A convex portion 321 is provided at the bottom of the carrier 32, and the convex portion 321 on the bottom of the carrier 32 is inserted into the slot 3111 of the lifting platform 311 to prevent the carrier 32 from moving on the lifting platform 311.

[0058] Since the sizes of power batteries of different models may be different, it is necessary to replace different types of carriers 32 according to different types of power batteries. The carrier 32 can be easily disassembled and installed on the lifting platform 311 by the way of the protrusion 321 and the slot 3111, thereby improving work efficiency.

[0059] The carrier 32 is provided with a limiting groove 322 for preventing the workpiece from being displaced.

[0060] Since the power battery needs to maintain this posture after flipping in order to facilitate the next processing, the limiting groove 322 can prevent the power battery from shifting after flipping, further improving the processing effect of the power battery.

[0061] See also Figure 2 The embodiment of the present application also provides a flipping device, including the flipping device described above, and also includes a transfer device 6, wherein the transfer device 6 is used to move the workpiece after the flipping device is rotated.

[0062] The transfer device 6 can be a mobile fixture or a robot.

[0063] Since the flipping device of the embodiment of the present application includes the flipping device in any of the above embodiments, it has the beneficial effects brought by the flipping device in any of the above embodiments, which will not be described in detail here.

[0064] The flipping device may also include a welding device and a rolling device, wherein the welding device is used to weld the workpiece, and the rolling device is used to roll the flipped workpiece. The welding device includes a laser and a welding fixture 7, wherein the welding fixture 7 is used to clamp the workpiece, and the laser welds the workpiece in the welding fixture 7. The rolling device includes a rolling member and a rolling fixture 8, wherein the rolling fixture 8 is used to clamp the workpiece, and the rolling member is used to roll the workpiece in the rolling fixture 8.

[0065] After the laser welds the workpiece in the welding fixture 7, the transfer device 6 transfers the workpiece in the welding fixture 7 to the flipping device. After the workpiece is flipped by the flipping device, the transfer device 6 transfers the flipped workpiece to the rolling fixture 8 of the rolling device, and the rolling part rolls the workpiece in the rolling fixture 8.

[0066] The working principle / process of the flip device provided in the embodiment of the present application is as follows:

[0067] After the welding device performs side welding on the top cover of the power battery, it is moved by the transfer device 6 to the carrier 32 of the lifting load-bearing assembly 3 located on one side of the rotating shaft 5. The rotating drive member 11 drives the rotating shaft 5 to rotate 90° toward the lifting load-bearing assembly 3 located on one side of the rotating shaft 5, so that the clamping assembly 2 on the rotating shaft 5 is close to the lifting load-bearing assembly 3 containing the power battery, and the clamping assembly 2 clamps the power battery on the carrier 32 of the lifting load-bearing assembly 3. The lifting drive member 31 of the lifting load-bearing assembly 3 located on one side of the rotating shaft 5 drives the carrier 32 to descend to move away from the power battery. The rotating drive member 11 drives the rotating shaft 5 to rotate 180° toward the lifting load-bearing assembly 3 located on the other side of the rotating shaft 5, so that the clamping assembly 2 on the rotating shaft 5 drives the power battery to flip 180°, turning the power battery from the top cover downward posture to the top cover upward posture, and placing the power battery on the carrier 32 of the lifting load-bearing assembly 3 located on the other side of the rotating shaft 5. The clamping assembly 2 releases the power battery onto the carrier 32, and the lifting drive component 31 of the lifting load-bearing assembly 3 located on the other side of the rotating shaft 5 drives the carrier 32 to descend to avoid the clamping assembly 2. The rotating drive component 11 drives the rotating shaft 5 to rotate 90° toward the lifting load-bearing assembly 3 located on one side of the rotating shaft 5 to avoid the transfer device 6. The transfer device 6 transfers the power battery to the rolling device for rolling.
