[0047] In order to solve the technical problem that the flipping device and the conveyor line in the prior art are not compatible, and after the flipping is completed, a grabbing mechanism is used to take the battery cell from the flipping device and place it on the conveyor line, which leads to a complex structure of the entire device and high manufacturing cost, the utility model provides a battery cell flipping device, which can flip the battery cell and place it on the conveyor belt by setting a vertically movable mounting seat, a horizontally rotating connecting seat and two clamping plates. There is no need to additionally set up a grabbing mechanism, the structure is simple and the cost is low.

[0048] See also Figure 1 , Figure 1 It is a structural schematic diagram of a battery cell flipping device in one embodiment of the utility model.

[0049] The utility model provides a battery cell flipping device, comprising a base, a conveyor belt 2, a mounting seat 3, a connecting seat 5 and a clamping assembly 7; the conveyor belt 2 is arranged on the base; the mounting seat 3 is movably mounted on the base along the vertical direction, and is located above the conveyor belt 2; the connecting seat 5 is rotatably mounted on the mounting seat 3 along the horizontal axis; the clamping assembly 7 comprises two clamping plates 71 and a driving mechanism, the two clamping plates 71 are arranged at intervals on one side of the connecting seat 5 along the horizontal direction, and the two clamping plates 71 are movably arranged in directions of approaching and moving away from each other, so that when the two clamping plates 71 are close to each other, the two clamping plates 71 are used to clamp the battery cell, and the driving mechanism is connected to the two clamping plates 71.

[0050] In this example, see Figures 1 to 3The conveyor belt 2 is arranged on the base; the mounting seat 3 is movably mounted on the base along the vertical direction and is located above the conveyor belt 2; the connecting seat 5 is rotatably mounted on the mounting seat 3 along the horizontal axis, and the two clamping plates 71 are arranged at intervals on one side of the connecting seat 5 along the horizontal direction, and the two clamping plates 71 are movably arranged in the direction of approaching and moving away from each other, so that when the two clamping plates 71 are close to each other, the two clamping plates 71 are used to clamp the battery cell, and the driving mechanism is connected to the two clamping plates 71. When in use, the battery cell in a vertical state is placed between the two clamping plates 71, and then the driving mechanism drives the two clamping plates 71 to move relative to each other, so that the two opposite sides of the battery cell are clamped by the two clamping plates 71. Then the connecting seat 5 rotates 90 degrees, driving the two clamping plates 71 and the battery cell to flip over, so that the battery cell is in a horizontal state and is set toward the conveyor belt 2, and the mounting seat 3 drives the clamping assembly 7 to move vertically downward to place the battery cell on the conveyor belt 2, and the driving mechanism drives the two clamping plates 71 to release the battery cell, and the mounting seat 3 returns vertically upward to the initial position, and at the same time the connecting seat 5 rotates 90 degrees in the opposite direction to return to the initial state, and then the conveyor belt 2 transports the horizontally placed battery cell to the next workstation. By setting a vertically movable mounting seat 3, a horizontally rotating connecting seat 5 and the coordinated use of two clamping plates 71, the battery cell can be flipped and placed on the conveyor belt 2 without the need for an additional grabbing mechanism, with a simple structure and low cost.

[0051] In this example, see Figures 2 to 4 The battery cell flipping device also includes a mounting frame 1, a first driving component 4 and a second driving component 6. The mounting frame 1 is installed on the base and is erected above the conveyor belt 2. The mounting seat 3 is slidably installed on the mounting frame 1 along the vertical direction. The first driving component 4 is arranged on the mounting frame 1, and the first driving component 4 is connected to the mounting seat 3 to drive the mounting seat 3 to move along the vertical direction. The mounting seat 3 is arranged in a frame structure as a whole. The connecting seat 5 is rotatably installed in the mounting seat 3. The second driving component 6 is arranged on the outside of the mounting seat 3. The second driving component 6 is connected to the connecting seat 5 to drive the connecting seat 5 to rotate.

[0052] Specifically, the specific form of the first driving component 4 is not limited, as long as it can drive the mounting base 3 to move. In the present embodiment, the first driving component 4 includes two first cylinders, and the two first cylinders are arranged on opposite sides of the mounting frame 1. The push rod of each first cylinder is connected to the mounting base 3 to drive the mounting base 3 to move through the two first cylinders.

[0053] Specifically, see Figures 4 to 6, both ends of the connecting seat 5 are rotatably mounted on the mounting seat 3 through a rotating shaft, and the rotating shaft extends out of the mounting seat 3; the second driving assembly 6 includes two driving groups, and the two driving groups are arranged on opposite sides of the mounting seat 3, each of the driving groups includes a gear 61, a rack 62 and a second cylinder 63, the gear 61 is fixedly mounted on one end of the rotating shaft, the rack 62 is slidably mounted on the outer side of the mounting seat 3, and the rack 62 is meshed with the gear 61, the second cylinder 63 is arranged on the outer side of the mounting seat 3, and the push rod of the second cylinder 63 is connected to one end of the rack 62, which is used to drive the rack 62 to move, and the gear 61 is driven to rotate by driving the rack 62, thereby driving the connecting seat 5 to rotate.

[0054] In one embodiment, see Fig. 9 The clamping plate 71 includes a mounting portion 711 and a clamping portion 712 connected in sequence, the mounting portion 711 and the clamping portion 712 are arranged perpendicular to each other, the mounting portion 711 is slidably installed on one side of the connecting seat 5, and the two clamping portions 712 and the two mounting portions 711 together enclose a clamping area, which is used to accommodate the battery cell.

[0055] In this embodiment, since the clamping plate 71 is movably arranged on one side of the connecting seat 5, and the clamping plate 71 also needs to effectively clamp the battery cell, the clamping plate 71 is divided into a mounting portion 711 and a clamping portion 712 which are connected in sequence, and the extension direction of the mounting portion 711 is consistent with the extension direction of the connecting seat 5, and the mounting portion 711 is slidably installed on one side of the connecting seat 5, and the extension direction of the clamping portion 712 is perpendicular to the extension direction of the connecting seat 5. The clamping portion 712 is used to clamp the battery cell, and the driving mechanism is connected to the mounting portion 711, so as to drive the connecting seat 5 to move by driving the mounting portion 711.

[0056] In one embodiment, see Figures 6 to 9 The clamping assembly 7 further includes a pad 73, which is detachably mounted on the mounting portion 711 and is located in the clamping area. The pad 73 is used to abut against the side of the battery.

[0057] In this embodiment, the clamping portion 712 can clamp both side surfaces of the battery cell. During the clamping process, the battery cell is prone to shake, resulting in inaccurate positioning of the battery cell. In order to solve this problem, a pad 73 is further provided in the clamping area. The pad 73 is installed on the mounting portion 711. When the battery cell is placed in the clamping area, the other side of the battery cell is close to the pad 73, thereby limiting the battery cell, preventing the battery cell from shaking, and improving the positioning accuracy.

[0058] In one embodiment, a plurality of the cushion blocks 73 are provided, each of the cushion blocks 73 has a different thickness, and a plurality of the cushion blocks 73 can be selectively installed on the installation portion 711 so that the thickness of the clamping area can be adjusted.

[0059] In this embodiment, when placing the battery cell on the conveyor belt 2, the side of the battery cell needs to be in contact with the battery cell. Therefore, the length of the clamping portion 712 needs to be slightly smaller than the thickness of the battery cell, so that the battery cell protrudes from the clamping portion 712. Since different types of battery cells have different thicknesses, in order to adapt to battery cells of different thicknesses, the thickness of the pad 73 needs to be adjusted in time. Therefore, a plurality of pads 73 of different thicknesses are provided. During specific use, the corresponding pad 73 can be selected according to the thickness of the battery cell, thereby ensuring that the battery cell always protrudes from the clamping portion 712.

[0060] In one embodiment, see Figures 6 to 9 The driving mechanism includes two driving cylinders 72, which are arranged opposite to each other. The two driving cylinders 72 correspond to the two clamping plates 71 one by one. The push rod of each driving cylinder 72 is connected to the mounting portion 711 to drive the clamping portion 712 to move.

[0061] In this embodiment, the two driving cylinders 72 are arranged opposite to each other, that is, the push rods of the two driving cylinders 72 are opposite to each other, that is, when the two push rods approach each other, the two clamping plates 71 are driven to approach each other and clamp, and when the two drag rods move away from each other, the two clamping plates 71 are driven to move away from each other to release the battery cells. By setting the two driving cylinders 72 to drive the two clamping plates 71 to move respectively, the structure is simple and easy to install and debug.

[0062] In one embodiment, see Figures 6 to 9 The connecting seat 5 has a first side and a second side that are arranged opposite to each other, the mounting portion 711 is slidably mounted on the first side, the driving cylinder 72 is mounted on the second side, and the connecting seat 5 is also provided with a through hole connecting the first side and the second side; the clamping assembly 7 also includes a connecting member 74, the connecting member 74 is passed through the through hole and the two ends are respectively connected to the push rod of the driving cylinder 72 and the mounting portion 711.

[0063] In this embodiment, the driving cylinder 72 and the clamping plate 71 are arranged on opposite sides of the connecting seat 5, and the push rod of the driving cylinder 72 and the mounting portion 711 are connected by the connecting member 74, so that the entire device structure is compact and the volume of the equipment is reduced.

[0064] In one embodiment, see Figures 6 to 9The mounting portion 711 is movably mounted on the connecting member 74 in a direction close to or away from another mounting portion 711, so that the position of the clamping portion 712 can be adjusted.

[0065] In the present embodiment, in order to make the structure of the whole device compact, the stroke of the selected driving cylinder 72 is relatively short, resulting in a limited range of motion of the clamping plate 71. In order to be able to clamp battery cells of different lengths, the mounting portion 711 is movably mounted on the connecting member 74 so that the position of the clamping portion 712 can be adjusted. Specifically, the two clamping plates 71 are arranged relatively to each other along a first direction, and each of the clamping plates 71 is movable along the first direction. The connecting member 74 is provided with a plurality of through holes, and the plurality of through holes are arranged at intervals along the first direction. The mounting portion 711 is provided with a threaded hole. The clamping plate 71 is connected to the mounting portion 711 by a screw connection. The screw connection can select one of the plurality of through holes to penetrate and be threadedly connected to the mounting portion 711. In this way, the position of the mounting portion 711 can be adjusted, thereby adjusting the distance between the two clamping portions 712 to adapt to battery cells of different sizes.

[0066] In one embodiment, see Figures 6 to 9 The clamping assembly 7 also includes a stop block 75 and a limit member 76. The stop block 75 is arranged on the second side and is located between the two driving cylinders 72. The limit member 76 is installed on the connecting member 74 and is arranged corresponding to the stop block 75. When the connecting member 74 moves, the limit member 76 abuts against the stop block 75 to limit the connecting member 74.

[0067] In this embodiment, since the clamping plate 71 is driven to move by the cylinder, a limiting member 76 is further provided on the connecting member 74 in order to limit the movement of the cylinder. When the connecting member 74 moves, it can drive the limiting member 76 to move, and the stop block 75 corresponds to the limiting member 76, so that it can abut against the limiting member 76 to limit it.

[0068] In one embodiment, the connecting member 74 is provided with a threaded hole; the limiting member 76 includes a screw rod, and the screw rod is threadedly connected to the connecting member 74 so that the length of the screw rod can be adjusted.

[0069] In this embodiment, in order to facilitate installation and debugging, the limiting member 76 is a screw rod, and the screw rod is threadedly connected to the connecting member 74, which is easy to use.

[0070] In one embodiment, see Figures 6 to 9A slide rail 78 is provided on one side of the connecting seat 5; the clamping assembly 7 also includes two sliders 77, and the two sliders 77 are slidably installed on the slide rail 78. The two clamping plates 71 correspond to the two sliders 77 one by one, and the clamping plates 71 are installed on the corresponding sliders 77 so that the clamping plates 71 are slidably installed on the connecting seat 5.

[0071] In this embodiment, the two clamping plates 71 are installed on the same slide rail 78 via the slider 77 , thereby ensuring the movement accuracy of the two clamping plates 71 .

[0072] In one embodiment, the connecting seat 5 is rotatably mounted on the mounting seat 3 along an axis in the conveying direction; two clamping assemblies 7 are provided, and the two clamping assemblies 7 are arranged at intervals along the conveying direction.

[0073] In order to better understand the present invention, the following Figures 1 to 9 The technical solution of the utility model is described in detail:

[0074] When in use, the battery cell in a vertical state is placed between the two clamping plates 71, and then the two driving cylinders 72 respectively drive the two clamping plates 71 to move closer to each other, so that the two opposite sides of the battery cell are clamped by the two clamping plates 71, and then the second driving component 6 drives the connecting seat 5 to rotate. After the connecting seat 5 rotates 90 degrees, the second driving component 6 stops. At this time, the two clamping plates 71 and the battery cell are turned over, so that the battery cell is in a horizontal state and is arranged toward the conveyor belt 2. The first driving component 4 drives the mounting seat 3 to move vertically downward, driving the clamping component 7 to move vertically downward. The battery cells are placed on the conveyor belt 2, the two driving cylinders 72 respectively drive the two clamping plates 71 to release the battery cells, the first driving component 4 then drives the mounting seat 3 to return to the initial position vertically upward, and the second driving component 6 drives the connecting seat 5 to rotate 90 degrees in the opposite direction to return to the initial state, and then the conveyor belt 2 transports the horizontally placed battery cells to the next station, and the battery cells can be turned over and placed on the conveyor belt 2 by setting a vertically movable mounting seat 3, a horizontally rotating connecting seat 5 and the two clamping plates 71.
