[0038] See also Figure 1 The flipping device provided in the embodiment of the present application is now described. The flipping device provided in the embodiment of the present application includes a mounting frame 1, a driving transmission assembly 2, a first driven transmission assembly 3, a second driven transmission assembly 4, a first clamping assembly 5, and a second clamping assembly 6.

[0039] The active transmission assembly 2 includes a rotation driving member 21 and a connecting rod 22 . The rotation driving member 21 is mounted on the mounting frame 1 . The rotation driving member 21 is in transmission connection with the connecting rod 22 to drive the connecting rod 22 to rotate.

[0040] The first driven transmission assembly 3 and the second driven transmission assembly 4 are arranged on the mounting frame 1, and are both connected to the connecting rod 22 of the active transmission assembly 2. The rotating driving member 21 drives the connecting rod 22 to rotate, thereby driving the first driven transmission assembly 3 and the second driven transmission assembly 4 to rotate simultaneously.

[0041] The first clamping assembly 5 and the second clamping assembly 6 are relatively arranged on the mounting frame 1. The first clamping assembly 5 and the second clamping assembly 6 are used to clamp both sides of the workpiece. The first clamping assembly 5 is transmission connected to the first driven transmission assembly 3, and the second clamping assembly 6 is transmission connected to the second driven transmission assembly 4.

[0042] The workpiece in the embodiment of the present application can be a soft-pack battery cell or a square battery cell, or other workpieces that need to be turned over. The connecting rod 22 rotates around its central axis, and its central axis is parallel to its length direction.

[0043] The rotary drive member 21 may include a rotary drive unit, a first driving gear, and a first driven gear. The rotary drive unit is in transmission connection with the first driving gear, which meshes with the first driven gear. The first driven gear is sleeved on the connecting rod 22. The rotary drive unit can rotate the connecting rod 22 via the first driving gear and the first driven gear. The rotary drive unit may be a rotary motor or a rotary cylinder.

[0044] The first driven transmission assembly 3 may include a second driving gear and a second driven gear. The second driving gear is connected to one end of the connecting rod 22, which is connected to the first clamping assembly 5. The second driving gear meshes with the second driven gear. The rotary drive member 21 rotates the connecting rod 22, which in turn drives the first clamping assembly 5 to rotate via the second driving gear and the second driven gear.

[0045] The second driven transmission assembly 4 may adopt the same structure as the first driven transmission assembly 3 .

[0046] The first clamping assembly 5 may include a first clamping driver, a first clamping plate, and a second clamping plate. The first clamping driver is connected to the first driven transmission assembly 3 and is in transmission connection with the first clamping plate and the second clamping plate. The first clamping driver drives the first clamping plate and the second clamping plate toward each other to clamp the workpiece, and drives the first clamping plate and the second clamping plate away from each other to release the workpiece. The first clamping driver may specifically be a pneumatic finger.

[0047] The first clamping assembly 5 may further include a mounting plate, a second clamping driver, a third clamping driver, a third clamping plate, and a fourth clamping plate. The second clamping driver and the third clamping driver are mounted on the mounting plate, which is connected to the first driven transmission assembly 3. The second clamping driver is in transmission connection with the third clamping plate, and the third clamping driver is in transmission connection with the fourth clamping plate. The second clamping driver and the third clamping driver respectively drive the third clamping plate and the fourth clamping plate toward each other to clamp the workpiece, and the second clamping driver and the third clamping driver respectively drive the third clamping plate and the fourth clamping plate away from each other to release the workpiece. The second clamping driver and the third clamping driver may be linear motors, pneumatic cylinders, or electric cylinders.

[0048] The second clamping assembly 6 can adopt the same structure as the first clamping assembly 5 .

[0049] Protective covers may be installed on the outer sides of the active transmission component 2 , the first driven transmission component 3 , and the second driven transmission component 4 .

[0050] In the embodiment of the present application, after the first clamping assembly 5 and the second clamping assembly 6 clamp the two sides of the workpiece, the rotary drive member 21 of the active transmission assembly 2 rotates the connecting rod 22, which drives the first driven transmission assembly 3 and the second driven transmission assembly 4 to simultaneously rotate the first clamping assembly 5 and the second clamping assembly 6, thereby flipping the workpiece. This improves production efficiency and meets production cycle requirements.

[0051] In addition, compared to rotating the clamping assembly on one side and then driving the clamping assembly on the other side to rotate through the workpiece, the flipping device of the present application does not transmit torque through the workpiece, thereby reducing the damage rate of the workpiece.

[0052] See also Figure 2 and Figure 3 The rotating driving member 21 includes a driving part 211, a rack 212 and a gear 213. The driving part 211 is installed on the mounting frame 1. The driving part 211 is connected to the rack 212 in transmission connection. The rack 212 is engaged with the gear 213. The gear 213 is sleeved on the connecting rod 22.

[0053] The drive unit 211 drives the rack 212 to move linearly, and the gear 213 meshing with the rack 212 converts the linear motion into rotational motion. The gear 213 drives the first and second driven transmission assemblies 3 and 4 through the connecting rod 22 to simultaneously rotate the first and second clamping assemblies 5 and 6, thereby flipping the workpiece.

[0054] The driving part 211 may be a linear motor, a pneumatic cylinder or an electric cylinder.

[0055] The rotary driving member 21 further includes a floating connection portion 214 , and the driving portion 211 is connected to the rack 212 via the floating connection portion 214 .

[0056] When the drive shaft of driver unit 211 is connected to another device, eccentricity or non-parallelism between the drive shaft and the other device can cause unsmooth movement. The floating connection 214 absorbs eccentric and lateral loads on the drive shaft of driver unit 211 caused by eccentricity or non-parallelism between the drive shaft and the other device, ensuring smooth and stable operation of driver unit 211.

[0057] The floating connection 214 may be a flexible metal bellows or a spring.

[0058] Preferably, the floating connection portion 214 includes a fixed connection sub-portion 2141 and a rotating connection sub-portion 2142 . The rotating connection sub-portion 2142 is connected to the rack 212 . The rotating connection sub-portion 2142 is rotationally connected to the fixed connection sub-portion 2141 . The fixed connection sub-portion 2141 is connected to the driving portion 211 .

[0059] One end of the rotating connection sub-part 2142 and the fixed connection sub-part 2141 is set to be spherical or hemispherical, and a limiting groove is set on the fixed connection sub-part 2141. The spherical or hemispherical end of the rotating connection sub-part 2142 is clamped in the limiting groove of the fixed connection sub-part 2141 to realize the rotating connection between the rotating connection sub-part 2142 and the fixed connection sub-part 2141.

[0060] Due to the rotational connection between the rotating connection sub-part 2142 and the fixed connection sub-part 2141, the rotating connection sub-part 2142 is allowed to swing in the limiting groove of the fixed connection sub-part 2141, so that even if the connection between the drive shaft and other devices is eccentric or non-parallel, the drive part 211 can still ensure smooth movement.

[0061] Preferably, see Figure 1 and Figure 4 The first driven transmission assembly 3 includes a first driving wheel 31, a first driven wheel 32 and a first synchronous belt 33. The first driving wheel 31 is connected to the connecting rod 22 of the active transmission assembly 2, the first driven wheel 32 is connected to the first clamping assembly 5, and the first synchronous belt 33 is sleeved on the first driving wheel 31 and the first driven wheel 32.

[0062] The first driving wheel 31 drives the first driven wheel 32 to rotate via the first synchronous belt 33, thereby rotating the first clamping assembly 5. Compared with transmission via gear meshing, this transmission method can increase the distance between the first clamping assembly 5 and the connecting rod 22, preventing the first clamping assembly 5 from colliding with the connecting rod 22 during rotation.

[0063] Keyways may be provided on the outer sides of the first driving wheel 31 and the first driven wheel 32 to increase the friction with the first synchronous belt 33 , thereby facilitating transmission by the first synchronous belt 33 .

[0064] The first driven transmission assembly 3 further includes a tensioning adjusting member 34 , which is connected to the first synchronous belt 33 to adjust the tension of the first synchronous belt 33 .

[0065] The first synchronous belt 33 will become loose after being used for a long time, resulting in the first driving wheel 31 being unable to drive the first driven wheel 32 to rotate. The tensioning adjusting member 34 can adjust the tension of the first synchronous belt 33 to ensure the operation of the first driven transmission assembly 3.

[0066] The tensioning adjusting member 34 may be a rod provided on the mounting frame 1. After the first synchronous belt 33 becomes loose, the first synchronous belt 33 may be wound around the first driving wheel 31, the first driven wheel 32 and the tensioning adjusting member 34 to tighten the first synchronous belt 33.

[0067] Preferably, the tensioning adjustment member 34 includes an adjusting wheel 341 and an adjusting connection portion 342, the adjusting wheel 341 is connected to the first synchronous belt 33, the adjusting connection portion 342 is connected to the adjusting wheel 341, the adjusting connection portion 342 is installed on the mounting frame 1, and the adjusting connection portion 342 is used to adjust the position of the adjusting wheel 341.

[0068] The adjustment connection 342 can be a pneumatic cylinder or a linear motor. The adjustment connection 342 drives the adjustment wheel 341 to move, thereby changing the position of the adjustment wheel 341, thereby increasing or decreasing the area enclosed by the first synchronous belt 33, that is, changing the circumference of the first synchronous belt 33 to adjust the tension of the first synchronous belt 33.

[0069] Preferably, an adjustment slot 11 is provided on the mounting frame 1, and the adjustment connection part 342 includes an adjustment connection sub-part and a fixed sub-part, the adjustment connection sub-part is connected to the adjustment wheel, the adjustment connection sub-part is passed through the adjustment slot 11, and is connected to the fixed sub-part to fix the position of the adjustment wheel 341 on the mounting frame 1.

[0070] The adjustment slot 11 is specifically a waist-shaped hole or an elongated through-hole. The adjustment connecting portion can be a screw, and the fixing portion can be a nut. The adjustment connecting portion and the fixing portion are threadedly connected, allowing the adjustment connecting portion to slide within the adjustment slot 11. The fixing portion is connected to the adjustment connecting portion and abuts against the edge of the adjustment slot 11, thereby fixing the position of the adjustment wheel 341 on the mounting bracket 1.

[0071] The flipping device further includes a lifting assembly 7, which includes a gantry 71 and a lifting drive 72. The lifting drive 72 is installed on the gantry 71, and the lifting drive 72 is transmission-connected to the mounting frame 1.

[0072] After the first clamping assembly 5 and the second clamping assembly 6 clamp the workpiece on the transport device, the lifting drive component 72 drives the first clamping assembly 5 and the second clamping assembly 6 on the mounting frame 1 to drive the workpiece away from the transport device, and the active transmission assembly 2, the first driven transmission assembly 3, and the second driven transmission assembly 4 then rotate the workpiece clamped by the first clamping assembly 5 and the second clamping assembly 6.

[0073] After the workpiece is flipped, the lifting drive 72 drives the first clamping assembly 5 and the second clamping assembly 6 on the mounting frame 1 to bring the workpiece close to the transport device. The first clamping assembly 5 and the second clamping assembly 6 release the workpiece onto the transport device, and the transport device transports the workpiece to the next workstation.

[0074] The lifting drive member 72 can be a linear motor or a cylinder. The gantry 71 is arranged across the transport device for transporting the workpiece.

[0075] A buffer may also be provided on one side of the mounting frame 1 close to the lifting drive member 72 to prevent the mounting frame 1 from colliding with the gantry 71 .

[0076] An embodiment of the present application also provides a production device, including the above-mentioned turning device.

[0077] Since the production equipment 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 repeated here.

[0078] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
