Currently, the application of power batteries is more widespread from the development of market situation. The power battery is not only applied to energy storage power supply systems such as hydraulic power, firepower, wind power and solar power stations, but also widely applied to electric vehicles such as electric bicycles, electric motorcycles, electric automobiles and other fields. With the continuous expansion of the application field of the power battery, the market demand of the power battery is also continuously expanding.

The battery cell is the smallest unit constituting the battery, and a plurality of battery cells may be directly assembled to form the battery, or may be first assembled to form a battery module, and then assembled from one or more battery modules to form the battery. In the process of assembling the battery cells to form a battery, the battery cells need to be placed in a case to form a finished structure.

However, in the production process of the battery cell, in order to facilitate assembly and operation of the battery cell in the early stage, the battery cell is generally arranged horizontally, and particularly for the cylindrical battery cell, the operation can be better performed in the horizontal arrangement due to the special shape of the cylindrical battery cell, that is, the axial direction of the cylindrical battery cell is arranged along the horizontal direction.

However, due to the tooling requirement or transmission requirement of equipment in the processing process, the horizontal cylindrical battery cell needs to be turned to be vertical, even if the axial direction of the cylindrical battery cell is arranged along the vertical direction, the cylindrical battery cell is convenient to carry out subsequent conveying or assembly.

In most of the current battery production lines, the overturning is usually performed manually, which results in low operation efficiency and affects the overall production and assembly efficiency of the battery.

Based on the above-mentioned considerations, in order to solve the problem of low operation efficiency when the current battery cell performs the overturning operation, one or more embodiments of the present application provide an overturning device, where the first overturning member and the second overturning member can respectively overturn the first battery cell and the second battery cell from a horizontal state to a vertical state, i.e. the axial directions of the first battery cell and the second battery cell are set along the vertical direction; therefore, the turnover efficiency of the battery can be improved, the first battery unit and the second battery unit can be quickly assembled to form the battery pack, and the battery pack can be conveniently assembled into the box body, so that the overall production and assembly efficiency of the battery can be effectively improved.

Referring to fig. 1 and 2, an embodiment of the application provides a turnover device 100, which includes a base 10, a first turnover member 20 and a second turnover member 30, wherein the first turnover member 20 is rotatably disposed on the base 10 around a first direction a, and has a first accommodating position 21 for accommodating a first battery unit 200. The second flipping member 30 is rotatably disposed on the base 10 around the first direction a and spaced apart from the first flipping member 20 along a second direction b intersecting the first direction a, and the second flipping member 30 has a second accommodating position 31 for accommodating the second battery unit 300. The first turning member 20 and the second turning member 30 are configured to drive the first battery unit 200 and the second battery unit 300 to turn to a vertical state, so as to form the battery pack 400.

It should be noted that the turnover device 100 provided by the present application may be used for turnover of a cylindrical battery cell, and may also be used for turnover of a square battery cell. For ease of understanding, a cylindrical cell will be described below as an example.

The base 10 refers to a structure capable of providing a mounting base for the first flipping member 20, the second flipping member 30, and other structures in the flipping unit 100. The first battery cell 200 and the second battery cell 300 are cell groups formed by arranging a plurality of cylindrical battery cells. Specifically, a plurality of cylindrical cells are arranged in a radial direction to form one or more columns, thereby forming the first battery cell 200 or the second battery cell 300.

The battery pack 400 is an integral structure formed by combining the first battery cell 200 and the second battery cell 300 together, and the battery pack 400 is assembled into a case, thereby forming a complete battery structure.

The first overturning member 20 is a structure capable of supporting and carrying the first battery unit 200 and driving the first battery unit 200 to overturn to a vertical state. The second overturning member 30 is a structure capable of supporting and carrying the second battery unit 300 and driving the second battery unit 300 to overturn to a vertical state. The vertical state refers to a state that the axial direction of the cylindrical battery cell is arranged along the vertical direction.

Further, the first direction a may be set to a first horizontal direction, that is, the first flipping member 20 and the second flipping member 30 are rotated around the first horizontal direction, respectively, so that the first battery cell 200 and the second battery cell 300 are flipped from the horizontal state to the vertical state.

The second direction b is perpendicular to the first direction a, and the second direction b may be set to a second horizontal direction perpendicular to the first horizontal direction. Thus, the first flipping member 20 and the second flipping member 30 are disposed at intervals along the second horizontal direction, and both are rotated around the first horizontal direction to face each other, so that the first battery cell 200 and the second battery cell 300 are assembled after flipping, thereby forming the battery pack 400.

Through the above structure, the first overturning piece 20 and the second overturning piece 30 can respectively overturn the first battery monomer and the second battery monomer from a horizontal state to a vertical state, i.e. the axial directions of the first battery monomer and the second battery monomer are arranged along the vertical direction. Therefore, not only can the overturning efficiency of the battery be improved, but also the first battery unit 200 and the second battery unit 300 can be quickly assembled to form the battery pack 400, so that the battery pack 400 can be conveniently assembled into the box body, and the overall production and assembly efficiency of the battery can be effectively improved.

In some embodiments, the first flipping member 20 and the second flipping member 30 have a first state and a second state during rotation. As shown in fig. 1, in the first state, the first battery unit 200 is horizontally disposed in the first storage position 21, and/or the second battery unit 300 is horizontally disposed in the second storage position 31. As shown in fig. 2, in the second state, the first battery unit 200 is disposed in the first accommodating position 21 in a vertical state, and/or the second battery unit 300 is disposed in the second accommodating position 31 in a vertical state.

Specifically, in the process of turning over the first battery unit 200 and the second battery unit 300, in the initial state, the first turning member 20 and the second turning member 30 are both in the first state, at this time, the first battery unit 200 and the second battery unit 300 are moved from the previous process to the turning device 100, the first battery unit 200 is moved to the first accommodating position 21, the second battery unit 300 is moved to the second accommodating position 31, and the first battery unit 200 and the second battery unit 300 are both in the horizontal state.

Further, the first overturning member 20 and the second overturning member 30 are controlled to rotate from the first state to the second state, and at the same time, the first battery unit 200 on the first accommodating position 21 overturns from the horizontal state to the vertical state along with the first overturning member 20, and the second battery unit 300 on the second accommodating position 31 overturns from the horizontal state to the vertical state along with the second overturning member 30, so that the first battery unit 200 and the second battery unit 300 can be overturned quickly.

Therefore, in the process of switching between the first state and the second state of the first turning member 20 and the second turning member 30, the first battery unit 200 and the second battery unit 300 thereon can be driven to be turned from the horizontal state to the vertical state rapidly, so as to improve the turning efficiency, and facilitate assembling the first battery unit 200 and the second battery unit 300 to form the battery pack 400 after the turning is completed.

In some embodiments, the first flip member 20 and the second flip member 30 each include a first support plate 22 and a second support plate 23, where the first support plate 22 and the second support plate 23 intersect and enclose a first accommodating position 21 and/or a second accommodating position 31. In the first state, the first battery cell 200 and/or the second battery cell 300 is supported on the first support plate 22. In the second state, the first battery cell 200 and/or the second battery cell 300 is supported on the second support plate 23.

Specifically, the first support plate 22 and the second support plate 23 are disposed perpendicular to each other, so as to enclose a first accommodating position 21 and a second accommodating position 31 which form a right angle.

In the first state, the first support plates 22 of the first turning member 20 and the second turning member 30 are disposed horizontally, and the second support plates 23 are disposed vertically. At this time, when the first battery unit 200 is placed on the first receiving position 21, the first battery unit 200 is supported on the first support plate 22, and the second support plate 23 can limit the first battery unit 200 in the horizontal direction. Likewise, when the second battery cell 300 is placed in the second receiving position 31, the second battery cell 300 is supported on the first support plate 22, and the second support plate 23 can position the second battery cell 300 in the horizontal direction.

At this time, the first turning member 20 and the second turning member 30 are controlled to rotate from the first state to the second state, i.e. the first support plate 22 is vertically disposed, and the second support plate 23 is horizontally disposed. At this time, the first battery unit 200 and the second battery unit 300 are supported on the corresponding second support plates 23, and the first support plates 22 limit the first battery unit 200 and the second battery unit 300 in the horizontal direction at this time.

Through setting up first backup pad 22 and second backup pad 23, can support and spacing first cell 200 and second cell 300 respectively under first state and second state to can realize that first cell 200 and second cell 300 switch over smoothly between horizontal state and vertical state, improve the stability of upset process.

In some embodiments, the first flipping member 20 and the second flipping member 30 further include an end plate 24, the end plate 24 is connected to two ends of the first support plate 22 and the second support plate 23 along the first direction a, and the outer periphery of the end plate 24 is in a circular arc shape. The turning device 100 further comprises a wheel 40 rotatably arranged on the base 10 about a first direction a, the end plate 24 being supported on the wheel 40.

Specifically, the end plate 24 is connected to two ends of the first support plate 22 and the second support plate 23 along the first direction a, on one hand, the end plate 24 can realize connection between the first support plate 22 and the second support plate 23, so that the first support plate 22 and the second support plate 23 form an integral structure, and stability is improved. On the other hand, the outer periphery of the end plate 24 is provided in a circular arc shape, specifically, three-quarters of a circular arc, that is, the first support plate 22 and the second support plate 23 enclose a quarter of a gap.

Further, the wheel 40 is rotatably provided on the base 10 so as to protrude around the first direction a, and the end plate 24 is supported on the wheel 40. Wherein the number of wheels 40 matches the number of end plates 24. Thus, when the first turning member 20 and the second turning member 30 rotate around the first direction a, the rotating wheel 40 not only can support the end plate 24, but also can rotate the end plate 24 on the rotating wheel 40 relative to the base 10, thereby realizing smooth rotation of the first turning member 20 and the second turning member 30.

Therefore, by providing the end plate 24 and the rotating wheel 40, not only the connection stability between the first support plate 22 and the second support plate 23 can be improved, but also the end plate 24 can smoothly rotate on the rotating wheel 40, so that the first support plate 22 and the second support plate 23 are driven to smoothly rotate, and the first state and the second state can be switched.

In some embodiments, the flipping device 100 further includes a first driving member 50, where one end of the first driving member 50 is connected to the base 10, and the other end of the first driving member 50 is connected to the first flipping member 20 or the second flipping member 30, and the first driving member 50 is used to drive the first flipping member 20 and the second flipping member 30 to rotate around the first direction a.

Specifically, the first driving member 50 can provide a driving force for switching the first flipping member 20 and the second flipping member 30 between the first state and the second state, so that the first flipping member 20 and the second flipping member 30 can rotate around the first direction a more stably under the driving of the first driving member 50.

Accordingly, the first driving member 50 can drive the first turning member 20 and the second turning member 30 to smoothly switch between the first state and the second state, thereby smoothly turning the first battery unit 200 and the second battery unit 300.

Referring to fig. 1 and 3 together, in some embodiments, the first driving member 50 includes a movable rail 51 and a tilting cylinder 52, wherein the movable rail 51 is disposed on the base 10 and has a supporting surface 53 disposed obliquely toward the first tilting member 20 or the second tilting member 30. One end of the flipping cylinder 52 is rotatably disposed on the supporting surface 53 around the first direction a, and the other end is rotatably connected to the first flipping member 20 or the second flipping member 30.

Specifically, the movable rail 51 may be, but not limited to, configured as a triangular prism structure, and has a supporting surface 53, wherein an included angle is formed between the supporting surface 53 and the upper surface of the base 10, and the supporting surface 53 is disposed obliquely toward the first flip 20 or the second flip 30.

Further, a rotation shaft may be provided on the support surface 53, and one end of the flipping cylinder 52 may be rotatably connected to the rotation shaft, and the other end of the flipping cylinder 52 may be also rotatably connected to the first support plate 22 of the first flipping member 20 and the second flipping member 30 through the rotation shaft.

Therefore, when the turning cylinder 52 drives the first turning member 20 and the second turning member 30 to rotate, the two ends of the turning cylinder 52 can rotate relative to the movable rail 51, the first turning member 20 and the second turning member 30, respectively, so as to drive the first turning member 20 and the second turning member 30 to smoothly rotate.

By providing the movable rail 51 and the overturning cylinder 52, the first overturning member 20 and the second overturning member 30 can be driven to smoothly rotate, and overturning of the first battery unit 200 and the second battery unit 300 can be smoothly achieved.

In some embodiments, the first driving member 50 is telescopically coupled between the base 10 and the first flipping member 20 and/or between the base 10 and the second flipping member 30.

Specifically, the overturning cylinder 52 is telescopically arranged, and one end of the overturning cylinder 52 is rotatably connected to the supporting surface 53, and the other end is rotatably connected to the first overturning member 20 and the second overturning member 30. Thus, the reversing cylinder 52 can realize the process of driving the first reversing element 20 and the second reversing element 30 to rotate through the telescopic movement of the reversing cylinder.

With the above structure, the first driving member 50 can be controlled to smoothly drive the first tilting member 20 and the second tilting member 30 to rotate by its own telescopic movement.

In some embodiments, the first driving member 50, the first flipping member 20, and the second flipping member 30 are all movably disposed on the base 10 along the second direction b.

When the first flipping member 20 and the second flipping member 30 are rotated from the first state to the second state, the flipping of the first battery unit 200 and the second battery unit 300 is completed, so that the first battery unit 200 and the second battery unit 300 are both in the vertical state.

At this time, the first and second flipping members 20 and 30 may be controlled to approach each other in the second direction b so that the first and second battery cells 200 and 300 can be smoothly assembled to form the battery pack 400, so that the battery pack 400 is subsequently assembled into the case.

Thus, through the above-described structure, it is possible to realize the assembly of the first and second battery cells 200 and 300 while realizing the overturning operation of the first and second battery cells 200 and 300, and smoothly form the battery pack 400, so that the battery pack 400 is assembled into the case in the subsequent process, and the assembly efficiency is improved.

In some embodiments, the turning device 100 further includes a sliding rail 60 extending along the second direction b and disposed on the base 10, and the first driving member 50, the first turning member 20, and the second turning member 30 are slidably disposed on the sliding rail 60 along the second direction b.

By providing the slide rail 60, not only stable installation of the first driving member 50, the first tilting member 20 and the second tilting member 30 can be realized, but also stable sliding of the first driving member 50, the first tilting member 20 and the second tilting member 30 thereon can be realized, the structure is simplified, and the operation is facilitated.

In some embodiments, the flipping device 100 further includes a second driving member 70 movably disposed on the base 10 along the second direction b, where the second driving member 70 is configured to drive the first driving member 50, the first flipping member 20, and the second flipping member 30 to move along the second direction b.
