Description

Technical Field

[0001] The present application relates to the field of lithium battery production equipment, and specifically to a flipping device. Background Art

[0002] During workpiece processing, a turning device is often required to turn the workpiece. For example, in the production of lithium batteries, the battery cell module needs to be turned over to perform processing on each side of the battery cell module.

[0003] Existing flipping devices include two opposing flipping mechanisms. After a handling device transfers a workpiece between the two flipping mechanisms, the two flipping mechanisms press the workpiece from both sides, completing the flipping of the workpiece. A major problem with existing flipping devices is that after transferring the workpiece between the two flipping mechanisms, the handling device must adjust the height of the workpiece and remain stationary for a long time. Only after the two flipping mechanisms have pressed the workpiece from both sides can the handling device release the workpiece and begin transferring the next workpiece. This affects the handling device's operating cycle and reduces production efficiency. Utility Model Content

[0004] In order to solve the above technical problems, the present application provides a flipping device, which adopts the following technical solutions:

[0005] A turning device includes a frame, a first turning mechanism, a second turning mechanism, and a lifting mechanism, wherein:

[0006] The first turning mechanism and the second turning mechanism are arranged on the frame in a relative manner;

[0007] The lifting mechanism is provided on the frame and is located between the first flipping mechanism and the second flipping mechanism. The lifting mechanism is configured to rise to support the workpiece to be flipped that is sent to the top of the lifting mechanism.

[0008] The first flipping mechanism and the second flipping mechanism are configured to clamp the workpiece to be flipped held by the lifting mechanism from both sides. The lifting mechanism is also configured to descend to avoid the flipping path of the workpiece to be flipped. The first flipping mechanism and the second flipping mechanism are also configured to cooperate to drive the workpiece to be flipped to flip vertically.

[0009] The flipping device provided by this application has a lifting mechanism disposed between the first flipping mechanism and the second flipping mechanism. The lifting mechanism is used to support the workpiece to be flipped and can automatically adjust the height of the workpiece to be flipped, ensuring that the first flipping mechanism and the second flipping mechanism press the workpiece to be flipped from the center of both ends of the workpiece to be flipped. In this way, after the handling device releases the workpiece to be flipped onto the lifting mechanism, it can then carry the next workpiece to be flipped, thereby speeding up the work cycle and improving production efficiency. The flipping device provided by this application is particularly suitable for flipping square workpieces such as battery modules.

[0010] In some embodiments, the lifting mechanism includes a base plate, a first lifting drive unit, a first lifting plate and at least one supporting member, wherein: the base plate is arranged on the frame; the first lifting drive unit is arranged on the base plate, the first lifting plate is connected to the driving end of the first lifting drive unit, and the supporting member is arranged on the first lifting plate; each supporting member is used to lift a workpiece to be flipped, and the first lifting drive unit is used to drive the first lifting plate to rise and fall, so as to drive the supporting member to rise and fall synchronously.

[0011] A lifting mechanism with a simple structure is provided, which drives the first lifting plate to rise and fall through the first lifting drive part to drive the bearing member arranged on the first lifting plate to support the workpiece to be flipped, and automatically adjusts the height of the workpiece to be flipped to ensure that the first flipping mechanism and the second flipping mechanism press the workpiece to be flipped from the center of both ends of the workpiece to be flipped.

[0012] In some embodiments, the lifting mechanism further includes a plurality of guide rods, a second lifting plate, a second lifting drive unit and at least one regularizing piece, wherein: the guide rod is slidably installed on the base plate in a vertical direction, and the upper end of the guide rod is connected to the first lifting plate; the second lifting plate is slidably connected to a plurality of guide rods, and the regularizing piece is arranged on the second lifting plate and corresponds to the carrier one by one; the second lifting drive unit is arranged on the second lifting plate, and the driving end of the second lifting drive unit is connected to the first lifting plate, and the second lifting drive unit is configured to drive the second lifting plate to rise and fall relative to the first lifting plate along the guide rod to drive the regularizing piece to rise and fall between the regularizing high position and the avoidance low position; when the regularizing piece rises to the regularizing high position, the regularizing end of the regularizing piece is higher than the bearing surface of the corresponding carrier, and the regularizing piece is used to regularize the workpiece to be flipped on the carrier; when the regularizing piece descends to the avoidance low position, the regularizing end of the regularizing piece is lower than the bearing surface of the carrier.

[0013] By providing a one-to-one correspondence between the aligning members and the supporting members, the aligning members can correct the position of the workpiece to be flipped after the supporting members have completed supporting the workpiece to be flipped. By placing the aligning members on a second lifting plate driven by a second lifting drive unit, the vertical position of the supporting members can be adjusted. When the aligning members descend to the avoidance low position, the aligning end of the aligning members is lower than the bearing surface of the supporting members, allowing the workpiece to be flipped to fall smoothly onto the supporting members. When the aligning members rise to the aligning high position, the aligning end of the aligning members is higher than the bearing surface of the corresponding supporting members, thereby implementing the aligning of the workpiece located on the supporting members.

[0014] In some embodiments, the tidying piece includes a first tidying plate, a second tidying plate and a tidying drive unit, wherein: the first tidying plate and the second tidying plate are slidably connected to the second lifting plate and are located on both sides of the corresponding supporting member; the tidying drive unit is arranged on the second lifting plate, and the tidying drive unit is configured to drive the first tidying plate and the second tidying plate to slide synchronously toward or away from the supporting member to implement the tidying of the workpiece to be flipped located on the supporting member.

[0015] A tidying piece with a simple structure is provided, which drives a first tidying plate and a second tidying plate to slide synchronously toward or away from a carrier through a tidying driving part, so as to tidy two opposite sides of a workpiece to be turned over on the carrier.

[0016] In some embodiments, the lifting mechanism includes two supporting members arranged side by side on the first lifting plate.

[0017] By providing two supporting members, the lifting mechanism can lift the two workpieces sequentially or synchronously, so that the first turning mechanism and the second turning mechanism can turn the two workpieces simultaneously.

[0018] In some embodiments, the carrier includes a first carrier plate and a second carrier plate that are arranged in pairs on the first lifting plate, and the first carrier plate and the second carrier plate cooperate to support the workpiece to be flipped.

[0019] A supporting member with a simple structure is provided, which can lift the workpiece to be flipped through the cooperation of a first supporting plate and a second supporting plate. On the premise of ensuring the lifting stability of the workpiece to be flipped, it can avoid the fragile structure at the bottom of the workpiece to be flipped (such as the pole at the bottom of the battery module) to prevent pressure loss to the fragile structure.

[0020] In some embodiments, a plurality of clearance grooves are provided at intervals on the supporting surfaces of the first supporting plate and the second supporting plate.

[0021] The first supporting plate and the second supporting plate can avoid the vulnerable structure at the bottom of the workpiece to be turned over, thereby preventing pressure damage to the vulnerable structure.

[0025] Two second flipping mechanisms with simple structures are provided, which drive the second clamping member to translate and rotate through the cooperation of the second translation drive part and the second rotation drive part, so that the second clamping member clamps the second end of the workpiece to be flipped and drives the workpiece to be flipped to rotate.

[0026] In some embodiments, the second rotary driving part is configured as a rotary cylinder.

[0039] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0040] like Figure 1 As shown, the turning device in the embodiment of the present application includes a frame 1, a first turning mechanism 2, a second turning mechanism 3 and a lifting mechanism, wherein:

[0041] The first turning mechanism 2 and the second turning mechanism 3 are arranged on the frame 1 opposite to each other.

[0042] The lifting mechanism 4 is disposed on the frame 1 and located between the first flipping mechanism 2 and the second flipping mechanism 3. The lifting mechanism 4 is configured to rise to support the workpiece to be flipped that is sent above the lifting mechanism 4. The workpiece to be flipped is, for example, a battery cell module 100.

[0043] The first flipping mechanism 2 and the second flipping mechanism 3 are configured to clamp the workpiece to be flipped, which is lifted by the lifting mechanism 4, from both sides. The lifting mechanism 4 is also configured to descend to avoid the flipping path of the workpiece to be flipped. The first flipping mechanism 2 and the second flipping mechanism 3 are also configured to cooperate to drive the workpiece to be flipped to flip vertically.

[0044] The optional working process of the flipping device in the embodiment of the present application is as follows:

[0045] The transport device transports the workpiece to be flipped to a predetermined height above the lifting mechanism 4 .

[0046] Then, the lifting mechanism 4 is controlled to rise so that the height difference between the lifting mechanism 4 and the workpiece to be turned reaches a predetermined target value. Then, the handling device releases the workpiece to be turned so that the workpiece to be turned falls onto the lifting mechanism 4.

[0047] Next, the lifting mechanism 4 descends to complete the height adjustment of the workpiece to be flipped, ensuring that the first flipping mechanism 2 and the second flipping mechanism 3 press and clamp the workpiece to be flipped from the centers of both ends of the workpiece to be flipped.

[0048] After the first and second turning mechanisms 2 and 3 have pressed and clamped the workpiece to be turned, the lifting mechanism 4 continues to descend, thereby separating the lifting mechanism 4 from the workpiece to be turned and avoiding the turning path of the workpiece to be turned. Finally, the first and second turning mechanisms 2 and 3 cooperate to drive the workpiece to be turned vertically.

[0049] The flipping device provided in the embodiment of the present application has a lifting mechanism 4 provided between the first flipping mechanism 2 and the second flipping mechanism 3. The lifting mechanism 4 is used to lift the workpiece to be flipped and can automatically adjust the height of the workpiece to be flipped to ensure that the first flipping mechanism 2 and the second flipping mechanism 3 press the workpiece to be flipped from the center of both ends of the workpiece to be flipped. In this way, after the handling device releases the workpiece to be flipped onto the lifting mechanism 4, it can carry out the handling of the next workpiece to be flipped, thereby speeding up the work rhythm and improving production efficiency. The flipping device of the embodiment of the present application is suitable for performing flipping operations on square workpieces such as battery cell modules 100. Of course, it can also perform flipping operations on other types of workpieces.

[0050] like Figure 2 and Figure 3 As shown, the lifting mechanism 4 optionally includes a base plate 41, a first lifting drive unit 42, a first lifting plate 43, and at least one supporting member 44. The base plate 41 is disposed on the frame 1. The first lifting drive unit 42 is disposed on the base plate 41. The first lifting plate 43 is connected to the driving end of the first lifting drive unit 42. The supporting members 44 are disposed on the first lifting plate 43. Each supporting member 44 is used to lift a workpiece to be flipped. The first lifting drive unit 42 is used to drive the first lifting plate 43 up and down, thereby driving the supporting members 44 to rise and fall synchronously.

[0051] It can be seen that by driving the first lifting plate 43 to rise and fall through the first lifting drive unit 42, the supporting member 44 provided on the first lifting plate 43 can be driven to support the workpiece to be flipped, and the height of the workpiece to be flipped can be automatically adjusted to ensure that the first flipping mechanism 2 and the second flipping mechanism 3 press and clamp the workpiece to be flipped from the center of both ends of the workpiece to be flipped.

[0052] The first lifting drive unit 42 is, for example, a cylinder arranged in the vertical direction. The first lifting plate 43 is connected to the top end of the telescopic rod of the cylinder. When the cylinder drives the telescopic rod to extend and retract, the first lifting plate 43 is driven to move up and down.

[0053] Optionally, the lifting mechanism 4 further includes a plurality of guide rods 45, a second lifting plate 46, a second lifting drive unit 47, and at least one aligning member 48. The guide rods 45 are vertically mounted on the base plate 41, with their upper ends connected to the first lifting plate 43. The second lifting plate 46 is also vertically and slidably connected to the plurality of guide rods 45. The aligning member 48 is disposed on the second lifting plate 46 and corresponds one-to-one with the support member 44. A second lifting drive unit 47 is disposed on the second lifting plate 46, with its driving end connected to the first lifting plate 43. The second lifting drive unit 47 is configured to drive the second lifting plate 46 to rise and fall relative to the first lifting plate 43 along the guide rods 45, thereby shifting the aligning member 48 between a high aligning position and a low avoidance position. When the aligning member 48 is raised to the high aligning position, its aligning end is above the supporting surface of the corresponding support member 44. The aligning member 48 is used to align the workpieces to be flipped on the support member 44. When the regulating member 48 descends to the avoidance low position, the regulating end of the regulating member 48 is lower than the bearing surface of the bearing member 44 .

[0054] In the initial state, the aligning member 48 is located at the avoidance low position, and the aligning end of the aligning member 48 is lower than the bearing surface of the carrier 44. At this time, the handling device can smoothly place the workpiece to be turned over on the carrier 44.

[0055] When the handling device places the workpiece to be flipped onto the carrier 44, and the aligning piece 48 rises to the aligning high position, the aligning end of the aligning piece 48 is higher than the supporting surface of the corresponding carrier 44. At this time, the aligning piece 48 can realize the position correction of the workpiece to be flipped, ensuring that the workpiece to be flipped can finally be firmly clamped by the first flipping mechanism 2 and the second flipping mechanism 3.

[0056] The second lifting drive unit 47 is, for example, a cylinder arranged in the vertical direction, the cylinder body of the cylinder is arranged on the second lifting plate 46, and the upper end of the telescopic rod of the cylinder is connected to the first lifting plate 43. When the cylinder drives the telescopic rod to extend and retract, it drives the first lifting plate 43 to slide and rise along the guide rod 45.

[0057] like Figure 3 As shown, optionally, the aligning member 48 includes a first aligning plate 481, a second aligning plate 482, and a aligning drive 483, wherein the first aligning plate 481 and the second aligning plate 482 are slidably connected to the second lifting plate 46 and are located on both sides of the corresponding support member 44. The aligning drive 483 is disposed on the second lifting plate 46 and is configured to drive the first aligning plate 481 and the second aligning plate 482 to slide synchronously toward or away from the support member 44 to implement aligning of the workpiece to be flipped located on the support member 44.

[0058] The regularization driving portion 483 may be, for example, a double-headed cylinder having two driving ends, and the first regularization plate 481 and the second regularization plate 482 are respectively connected to one of the driving ends of the double-headed cylinder.

[0059] like Figure 3 As shown, optionally, the lifting mechanism 4 includes two supporting members 44 arranged side by side on the first lifting plate 43. By providing two supporting members 44, the lifting mechanism 4 can lift the two workpieces sequentially or synchronously, so that the first flipping mechanism 2 and the second flipping mechanism 3 can flip the two workpieces simultaneously, thereby improving the flipping efficiency of the workpieces.

[0060] like Figure 1 and Figure 4 As shown, the flipping device in the embodiment of the present application is suitable for flipping the battery cell module 100. Before flipping, the side of the battery cell module 100 provided with the pole 101 faces downward, and the flipping device in the embodiment of the present application is used to flip the side provided with the pole 101 to face upward.

[0061] like Figure 4 As shown, the supporting member 44 optionally includes a first supporting plate 441 and a second supporting plate 442 arranged in a pair on the first lifting plate 43. The first supporting plate 441 and the second supporting plate 442 cooperate to support the workpiece to be flipped. The first supporting plate 441 and the second supporting plate 442 cooperate to lift the battery module 100. While ensuring the stability of the lifting of the battery module 100, the poles 101 on the battery module 100 can be avoided to prevent pressure damage to the poles 101.

[0062] Optionally, a plurality of clearance grooves 443 are provided at intervals on the bearing surfaces of the first bearing plate 441 and the second bearing plate 442. The clearance grooves 443 can prevent the first bearing plate 441 and the second bearing plate 442 from contacting the poles 101 on the battery module 100.

[0063] like Figure 5 As shown, optionally, the first flipping mechanism 2 includes a first mounting bracket 21, a first translation drive unit 22, a first clamping member 23, and a first rotation drive unit 24, wherein: the first mounting bracket 21 is slidably connected to the frame 1 and is in transmission connection with the first translation drive unit 22 provided on the frame 1, and the first translation drive unit 22 is used to drive the first mounting bracket 21 to slide toward or away from the lifting mechanism 4. The first clamping member 23 is rotationally connected to the first mounting bracket 21 and is in transmission connection with the first rotation drive unit 24 provided on the first mounting bracket 21. The first clamping member 23 is used to clamp the first end of the workpiece to be flipped, and the first rotation drive unit 24 is used to drive the first clamping member 23 to rotate.

[0064] It can be seen that the first translation drive unit 22 and the first rotation drive unit 24 cooperate to drive the first clamping member 23 to translate and rotate, so that the first clamping member 23 clamps the first end of the workpiece to be flipped and drives the workpiece to be flipped to rotate.

[0065] Similarly, the second flipping mechanism 3 includes a second mounting bracket 31, a second translational drive unit 32, a second clamping member 33, and a second rotational drive unit 34. The second mounting bracket 31 is slidably connected to the frame 1 and is in transmission connection with the second translational drive unit 32 disposed on the frame 1. The second translational drive unit 32 is used to drive the second mounting bracket 31 to slide toward or away from the lifting mechanism 4. The second clamping member 33 is rotationally connected to the second mounting bracket 31 and is in transmission connection with the second rotational drive unit 34 disposed on the second mounting bracket 31. The second clamping member 33 is used to clamp the second end of the workpiece to be flipped, and the second rotational drive unit 34 is used to drive the second clamping member 33 to rotate.

[0066] It can be seen that the second translation drive unit 32 and the second rotation drive unit 34 cooperate to drive the second clamping member 33 to translate and rotate, so that the second clamping member 33 clamps the second end of the workpiece to be flipped and drives the workpiece to be flipped to rotate.

[0067] Optionally, the first clamping member 23 and the second clamping member 33 have the same structure. Taking the first clamping member 23 as an example, it includes anti-falling blocks arranged above and below and side anti-falling plates arranged opposite to each other on both sides. The anti-falling blocks and the side anti-falling plates together form a first clamping space for clamping the first end of the workpiece. When the first translation drive unit 22 drives the first clamping member 23 to move toward the workpiece to be flipped, the first end of the workpiece to be flipped is snapped into the first clamping space. Similarly, when the second translation drive unit 32 drives the second clamping member 33 to move toward the workpiece to be flipped, the second end of the workpiece to be flipped is snapped into the second clamping space. In this way, it is achieved that the first clamping member 23 and the second clamping member 33 cooperate to clamp and fix the workpiece from both ends.

[0068] By the attached Figure 5It can be seen that the first clamping member 23 and the second clamping member 33 are not vertically symmetrical structures. Therefore, after the workpiece is flipped 180° by the first clamping member 23 and the second clamping member 33, the first clamping member 23 and the second clamping member 33 need to be reset after the workpiece is removed in order to clamp the next workpiece. In order to achieve the reset of the first clamping member 23 and the second clamping member 33, it is necessary to configure the first rotation drive unit 24 and the second rotation drive unit 34 respectively. Therefore, the first translation drive unit 22 can use a component with a large driving force. The first translation drive unit 22 can drive the first clamping member 23, the workpiece, and the second clamping member 33 to flip synchronously. After the workpiece is removed, the first translation drive unit 22 drives the first clamping member 23 to flip and reset. The second rotation drive unit 34 only needs to drive the second clamping member 33 to flip. Therefore, the second rotation drive unit 34 can use a rotary cylinder with a small driving force, light weight, and low cost.

[0069] Optionally, the first translation drive unit 22 and the second translation drive unit 32 can adopt various existing linear drive modules that can drive the first clamping member 23 and the second clamping member 33 to translate. For example, the first translation drive unit 22 is a screw drive module, and the second translation drive unit 32 is a cylinder drive module.

[0070] Optionally, the first rotation drive unit 24 and the second rotation drive unit 34 are rotary cylinders. The rotary cylinders can drive the corresponding first clamping member 23 and the second clamping member 33 to rotate quickly and stably. Moreover, the rotary cylinders are lightweight, thereby reducing the driving load of the first translation drive unit 22 and the second translation drive unit 32.

[0071] The above description of the present application is sufficiently detailed and has certain particularities. Those skilled in the art should understand that the descriptions in the embodiments are merely exemplary, and that all changes made without departing from the true spirit and scope of the present application should fall within the scope of protection of the present application. The scope of protection claimed in the present application is defined by the claims, not by the above description in the embodiments. Furthermore, the embodiments mentioned in the present application are not limited to being implemented individually, and some embodiments can also be implemented in combination.
