Description

Technical Field

[0001] The present application belongs to the field of battery processing technology, and more specifically, relates to a flipping and translation device and battery production equipment. Background Art

[0002] Square aluminum shell batteries need to be combined with multiple groups of battery cells to increase the energy capacity of the battery. Before combining multiple groups of battery cells, the single group of battery cells needs to be combined, and then the connecting pieces of several combined battery cell groups need to be welded. However, before the single group of battery cells are combined, some battery cell groups may have connecting piece directions that do not meet the requirements of the combination due to the previous processing steps. If the battery cell group is combined directly, the connecting piece will be sandwiched between the two battery cells, making it impossible to carry out the subsequent processes of combining the battery cells, resulting in jams and stagnation of the production process.

[0017] The flipping and translation device and battery production equipment provided by the embodiments of the present application have the following beneficial effects: the flipping and translation device of the embodiments of the present application flips a battery cell group whose connection tab direction does not meet the requirements of the core assembly process through a flipping assembly, so that the connection tab direction of the battery cell group meets the requirements of the core assembly process; the carrying platform of the translation assembly carries the flipped battery cell group, and drives the carrying platform to move the battery cell group to the next processing step through a moving drive member, thereby preventing the production process from being stuck or stagnant due to the connection tab direction of the battery cell group not meeting the requirements of the core assembly process;

[0031] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0032] See also Figure 1 and Figure 2 , the flipping and translation device provided in the embodiment of the present application is now described. The flipping and translation device provided in the embodiment of the present application includes a flipping assembly 1 and a translation assembly 2. The flipping assembly 1 is used to flip at least two workpieces around a horizontal axis, and the translation assembly 2 includes a carrying platform 21 and a movable driving member 22. The movable driving member 22 is connected to the carrying platform 21 in a transmission manner to drive the carrying platform 21 to reciprocate between two processing stations. The carrying platform 21 is used to carry the workpiece after the flipping assembly 1 is flipped. At least two first stations for placing workpieces are provided on the carrying platform 21. A positioning member 211 is provided between the two first stations. The positioning member 211 is used to push the two workpieces away from each other.

[0033] The workpiece in the embodiment of the present application may be a battery cell group whose connecting piece direction does not meet the requirements of the core assembly process. In addition, the workpiece may also be other workpieces that need to be turned over for processing.

[0034] The flip assembly 1 may include a gripper for picking up the battery cell group to be flipped and a rotary cylinder. The gripper is connected to the rotary cylinder to drive the gripper to rotate, thereby flipping the battery cell group. The flip assembly 1 flips the battery cell group 180° around the horizontal axis to change the orientation of the connecting tabs on the battery cell group.

[0035] The first workstations on the carrying platform 21 are arranged in pairs to facilitate the placement of battery cell groups.

[0036] The moving drive member 22 can be a linear motor, a pneumatic cylinder or an electric cylinder. The moving drive member 22 is used to drive the carrying platform 21 to move horizontally below the flip assembly 1.

[0037] Generally, a cell group with the connecting tabs facing upwards that does not meet the requirements of the core assembly process needs to be turned over so that the connecting tabs face downwards. In this way, the connecting tabs of the cell group can be exposed after the core assembly process.

[0038] The positioning member 211 may include a telescopic cylinder and a push rod, the push rod is used to contact a single battery cell, the telescopic cylinder is connected to the push rod to drive the push rod close to or away from the battery cell, the telescopic cylinder drives the push rod close to the battery cell so that the push rod pushes the single battery cell, so that the single battery cell is away from another battery cell in the battery cell group, so that the distance between the two battery cells in the battery cell group is increased, so that the robot can pick up two battery cells at the same time or other devices can process the two battery cells at the same time.

[0039] The battery cell group whose connecting piece direction does not meet the requirements of the core joining process is placed on the flipping component 1. The flipping component 1 flips the battery cell group whose connecting piece direction does not meet the requirements of the core joining process so that the connecting piece direction of the battery cell group meets the requirements of the core joining process. The carrying platform 21 of the translation component 2 carries the flipped battery cell group and drives the carrying platform 21 to move the battery cell group to the next processing step through the moving drive part 22. This can prevent the production process from being stuck and stagnant due to the connecting piece direction of the battery cell group not meeting the requirements of the core joining process.

[0040] The positioning member 211 on the carrying platform 21 can prevent the two cells of the cell group from shifting in position during the flipping and transfer process, resulting in a small distance between the cells, making it difficult for the robot to pick up the two cells at the same time, or making it difficult for the processing device to process the two cells at the same time.

[0041] Preferably, see Figure 3 The positioning member 211 includes a positioning driving member 2111 and two stops 2112. The positioning driving member 2111 is installed on the carrying platform 21. The two stops 2112 are transmission-connected to the positioning driving member 2111. The positioning driving member 2111 is used to drive the two stops 2112 to move closer to or away from each other. When the two stops 2112 move away from each other, they push the two workpieces on the first workstations away from each other.

[0042] The stopper 2112 can be configured as a baffle or a push block, preferably a baffle that takes up less space. The positioning drive member 2111 is a bidirectional cylinder, which can reduce one drive member.

[0043] The first workstation is provided with a spacer 212 for supporting the workpiece.

[0044] Since the connecting tabs of the flipped battery cell group face downward, if the connecting tabs are long, the supporting platform 21 may abut against the connecting tabs, causing the connecting tabs to bend. Therefore, the flipped battery cell group needs to be raised by the raising member 212 .

[0045] A support block for supporting the connecting piece may be further provided between the two first workstations to prevent the connecting piece from falling between the battery cells.

[0046] A first clamping member 213 is provided on a side of the raising member 212 , and the first clamping member 213 is used to clamp a workpiece.

[0047] The first clamping member 213 includes a first abutting portion, a first clamping drive portion, a second abutting portion, and a second clamping drive portion. The first abutting portion and the second abutting portion are relatively arranged on both sides of the raising member 212. The first clamping drive portion is transmission-connected to the first abutting portion, and the second clamping drive portion is transmission-connected to the second abutting portion. The first clamping drive portion and the second clamping drive portion respectively drive the first abutting portion and the second abutting portion to approach each other to clamp the battery cell, and move away from each other to release the battery cell.

[0048] The first clamping drive unit and the second clamping drive unit can be electric cylinders or pneumatic cylinders.

[0049] The first clamping member 213 can prevent the battery cell from moving when the carrying platform 21 moves in the horizontal direction.

[0050] The translation assembly 2 also includes a translation base 23 and a lifting drive member 24. The translation base 23 is transmission-connected to the mobile drive member 22. The lifting drive member 24 is arranged on the translation base 23. The lifting drive member 24 is transmission-connected to the supporting platform 21 to drive the supporting platform 21 to move in a direction close to or away from the flip assembly 1.

[0051] The lifting drive 24 can be a linear motor, electric cylinder, or pneumatic cylinder. After the flip assembly 1 flips the battery pack, the mobile drive 22 drives the carrier platform 21 to move horizontally to the bottom of the flip assembly 1. The lifting drive 24 drives the carrier platform 21 vertically toward the flip assembly 1. The flip assembly 1 releases the battery pack and transfers it to the carrier platform 21. The lifting drive 24 drives the carrier platform 21 vertically away from the flip assembly 1. The mobile drive 22 drives the carrier platform 21 horizontally to the next processing station.

[0052] The translation assembly 2 further includes a displacement detection member, which is used to detect the displacement of the lifting drive member 24 .

[0053] The displacement detection member may be a photoelectric sensor or a displacement sensor, in order to detect the displacement of the carrying platform 21 driven by the lifting drive frame in the vertical direction, and prevent the carrying platform 21 from colliding with the flip assembly 1.

[0054] See also Figure 4The flip assembly 1 includes a flip platform 11 and a flip driving member 12. The flip driving member 12 is connected to the flip platform 11 for flipping the flip platform 11. At least two second workstations are provided on the flip platform 11. The second workstations are used to place the workpiece to be flipped.

[0055] The flip assembly 1 further comprises a bracket, on which a flip drive 12 is mounted and in transmission connection with the flip platform 11. The flip drive 12 can be a rotary motor or a rotary cylinder. The second station corresponds to the first station and is arranged in pairs.

[0056] The flipping platform 11 is further provided with an anti-slipping member 13 , and the anti-slipping member 13 is used to support the workpiece after the flipping platform 11 is flipped.

[0057] The anti-drop member 13 may include a cylinder and a support plate, which is in transmission connection with the support plate to drive the support plate toward or away from the battery cell along the horizontal direction of the flip platform 11. When the support plate approaches the battery cell, the support plate is located above the battery cell. After the flip platform 11 is flipped, the support plate is located below the battery cell to prevent the battery cell from falling due to gravity.

[0058] Preferably, the anti-slip component 13 includes a rotating part 131 and a supporting part 132. The rotating part 131 is arranged on the flip platform 11. The rotating part 131 is transmission-connected to the supporting part 132 to drive the supporting part 132 to rotate toward or away from the workpiece. The supporting part 132 is used to abut against the workpiece.

[0059] The rotating portion 131 is a rotating motor or a rotating cylinder, and the supporting portion 132 is a baffle. The rotating portion 131 drives the supporting portion 132 to rotate about a horizontal axis parallel to the flip platform 11, bringing the supporting portion 132 close to the battery cell. After the flip platform 11 flips, the supporting portion 132 is located below the battery cell, preventing the battery cell from falling due to gravity.

[0060] The second workstation is provided with a second clamping member 14 , and the second clamping member 14 is used to clamp a workpiece.

[0061] The second clamping member 14 may have the same structure as the first clamping member 213 .

[0062] An embodiment of the present application also provides a battery production device, including the flipping and translation device described above.

[0063] Since the battery production equipment of the embodiment of the present application includes the flipping and translation device in any of the above embodiments, it has the beneficial effects brought by the flipping and translation device in any of the above embodiments, which will not be repeated here.

[0064] The above description is only a preferred embodiment of the present application and is 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.
