[0002] When cells are automatically produced on the module production line, multi-tray stacking is a common loading method.

[0042] See also Figure 1 and Figure 2 , Figure 1 A three-dimensional diagram of a cell feeding device in an embodiment of the utility model is shown. Figure 2 A side view of a battery cell loading device in one embodiment is shown.

[0043] An embodiment of the utility model provides a battery cell loading device, including a support 10, a lifting mechanism 20, a telescopic mechanism 30, a frame 50 and a first conveying assembly 51. The support 10 is arranged on the frame 50, and the support 10 is used to support the battery cell through the first conveying assembly 51. Optionally, the battery cell can be placed in a battery cell tray 40, and multiple battery cell trays 40 are stacked. At this time, the support 10 is used to support the battery cell tray 40 to achieve support for the battery cell. The lifting mechanism 20 is used to lift the battery cell tray, and then lift the battery cell from a lower position to a higher position. When the battery cell is placed on the battery cell tray 40, the lifting mechanism 20 is used to lift the battery cell tray 40 to a higher position, so that the battery cell on the tray on the top layer can be removed by a robotic arm (not shown in the figure), and finally the empty tray can be removed. Since the lifting mechanism 20 lifts the cell tray 40 to a higher position, the cell tray 40 is prone to shake and cause the cells to fall. The telescopic mechanism 30 is used to abut the lifting mechanism 20 to limit its movement, thereby preventing the cells from shaking and falling.

[0044] The support member 10 is disposed on the frame 50 and can move relative to the frame 50 in a first direction. The first conveying assembly 51 is used for loading the battery tray 40 and can support the battery tray 40. The lifting mechanism 20 is connected to the support member 10 and is used to control the support member 10 to move in the first direction to drive the movement of the first conveying assembly 51 and the battery tray 40. Optionally, the first direction can be a vertical direction or a substantially vertical direction.

[0045] In some embodiments, the stacked multi-layer battery trays 40 are placed entirely on the support 10. After the robot arm takes away the battery cells and battery tray 40 at the top, the lifting mechanism 20 is required to lift the remaining battery trays 40 to a height that can be grasped by the robot arm, so as to facilitate grasping of the battery cells in the next layer of battery trays 40. This process is repeated multiple times until all the battery cells are taken away.

[0046] The lifting mechanism 20 includes a first driving member 21, a screw rod 22 extending in a first direction, and a stopper 23. The screw rod 22 is disposed in the support member 10 and is threadedly connected to the support member 10. The first driving member 21 is used to drive the screw rod 22 to rotate so that the support member 10 moves along the extension direction of the screw rod 22. The screw rod 22 can convert rotational motion into linear motion, that is, the rotation of the screw rod 22 can enable the support member 10 to achieve linear motion. The rotation direction of the screw rod 22 is different, and the moving direction of the support member 10 is also different, so that the rotation direction of the screw rod 22 can be controlled, and then the lifting or lowering of the support member 10 can be controlled. One end of the screw rod 22 is connected to the first beam 55, and the other end is connected to the second beam 56, so the first driving member 21 can control the support member 10 to move between the first beam 55 and the second beam 56.

[0047] The stopper 23 is fixed on the screw rod 22 and is arranged at one end of the screw rod 22 close to the second cross beam 56, and can rotate with the screw rod 22. Exemplarily, the stopper 23 is sleeved on the screw rod 22 and is fixedly connected to the screw rod 22, so that the stopper 23 can rotate with the screw rod 22.

[0048] Exemplarily, the lifting mechanism 20 is located on the side of the support 10 to lift and lower the support 10. Furthermore, two lifting mechanisms 20 can be provided, respectively located on both sides of the support 10, to lift the battery cells synchronously, which can improve the stability of the battery cells when lifting and further prevent the battery cells from falling.

[0049] The telescopic mechanism 30 includes a telescopic end 32, and the telescopic end 32 includes an extended state and a retracted state. Figure 3 and Figure 4 As shown, Figure 3 and Figure 4 Shows Figure 2 A magnified view of area A, where Figure 3 The telescopic end 32 of the telescopic mechanism 30 is in an extended state. Figure 4 The telescopic end of the telescopic mechanism 30 is in the retracted state. When the telescopic end 32 is in the extended state, it is located on the rotation path of the stopper 23 to limit the rotation of the stopper 23, thereby limiting the displacement of the support member 10.

[0050] When the telescopic end 32 of the telescopic mechanism 30 is in the extended state, it abuts against the lifting mechanism 20, limiting the lifting and falling movements of the lifting mechanism 20. Since the lifting mechanism 20 is restricted in movement, the battery tray 40 can maintain stability and prevent the battery cells from falling. Exemplarily, the telescopic mechanism 30 is driven by a second driving member. When the telescopic end 32 is in the retracted state, it does not contact the lifting mechanism 20, thereby not limiting the movement of the lifting mechanism 20, and the lifting mechanism 20 can drive the battery tray 40 to rise.

[0051] Specifically, when the support member 10 is lifted to a certain height driven by the screw rod 22, if the motor 211 is accidentally shut down or the equipment shakes, the screw rod 22 may rotate in the opposite direction, causing the battery cell tray 40 to move down or even fall. At this time, the retractable end 32 is controlled to extend. Since the stopper 23 can rotate with the screw rod 22, and the retractable end 32 is located on the rotation path of the stopper 23 after being extended, the retractable end 32 limits the rotation of the stopper 23, and then limits the rotation of the screw rod 22, so that the position of the support member 10 is fixed, thereby preventing the battery cell from accidentally falling.

[0052] In the above-mentioned battery cell loading device, the first conveying assembly 51 is arranged on the support member 10, and can support the battery cell tray 40. When the support member 10 moves along the first direction, it can drive the first conveying assembly 51 to move, and then drive the battery cell tray 40 to move. The lifting mechanism 20 includes a first driving member 21, a screw rod 22 and a stopper 23. The stopper 23 is fixed on the screw rod 22 and can rotate with the screw rod 22. The first driving member 21 is used to drive the screw rod 22 to rotate to drive the support member 10 to move. The telescopic mechanism 30 includes a telescopic end 32. When the telescopic end 32 is in an extended state, it is located on the rotation path of the stopper 23 and can abut the stopper 23 to limit the displacement of the support member 10, so that the support member 10 is fixed to prevent its shaking from causing the battery cell to fall.

[0053] Exemplarily, the battery cells may be square battery cells, and the battery cells may be placed in a battery cell tray and loaded by a battery cell loading device.

[0054] Exemplarily, the telescopic mechanism 30 can be configured at the bottom or top of the lifting mechanism 20, that is, located at the first beam 55 or the second beam 56. Preferably, the telescopic mechanism 30 can be configured at the top of the lifting mechanism 20, that is, at the position of the second beam 56.

[0055] In some embodiments, the support member 10 includes a pair of support frames 11 and a connecting plate 12; the pair of support frames 11 extend along the second direction and are spaced apart at opposite sides of the frame 50 to provide support. The screw rod 22 is disposed on the support frame 11 and is threadedly connected to the support frame 11. Thus, when the first driving member 21 drives the screw rod to rotate, the screw rod 22 can rotate relative to the support frame 11.

[0056] The connecting plate 12 is connected between the supporting frames 11, and the first transmission assembly 51 is fixed on the connecting plate 12. At this time, the first driving member 21 drives the screw rod 22 to rotate to make the supporting frame 11 move upward, and the first transmission assembly 51 is arranged on the connecting plate 12, and the movement of the supporting frame 11 can synchronously drive the first transmission assembly 51 to move.

[0057] Please refer to Figure 2The first driving member 21 is arranged on the frame 50. The first driving member 21 includes a motor 211, a transmission chain 212 and a gear set (not shown). The gear set includes a first gear and a second gear. The output end of the motor 211 is connected to the first gear and can drive the first gear to rotate. The transmission chain 212 connects the first gear and the second gear. The second gear is sleeved and fixed on the screw rod 22. The second gear can rotate with the first gear under the drive of the transmission chain 212, thereby driving the screw rod 22 to rotate. Further, the screw rod 22 is threadedly connected to the support member 10, and the rotation of the screw rod 22 can drive the support member 10 to move along the first direction. Specifically, the motor 211 can be a servo motor.

[0058] For example, the stopper 23 may be a structure protruding from the screw rod 22, such as a square structure or other polygonal structure, and correspondingly, the retractable end 32 may be a cylindrical structure, a square structure or a polygonal structure. Figure 5 As shown, Figure 5 This is a schematic diagram of the state when the retractable end of an embodiment stops the stopper, and the figure shows the cross-sectional position relationship between the screw rod 22, the stopper 23 and the retractable end 32. The stopper 23 is a square structure, and the retractable end 32 is also a square structure. The retractable end 32 is located on the rotation path ω of the stopper 23. In the present application, the structure of the stopper 23 and the structure of the retractable end 32 are not limited, and the retractable end 32 can block the rotation of the stopper 23.

[0059] Optionally, the number of the stoppers 23 may be multiple, and the multiple stoppers 23 are arranged on the screw rod 22 along the circumference of the screw rod 22, and there is a gap between two adjacent stoppers 23, and the gaps between two adjacent stoppers 23 are equal or unequal. For example, the number of the stoppers 23 may be four, and the four stoppers 23 are evenly spaced and distributed on the side of the screw rod 22. Exemplarily, the telescopic end 32 of the telescopic mechanism 30 extends into the gap between the stoppers 23, such as Figure 6 As shown, there are four stoppers 23, which are arranged at intervals on the circumference of the screw rod 22. When the retractable end 32 is extended, it is located in the interval between the stoppers 23, that is, it is located on the rotation path ω of the stoppers 23, thereby limiting the rotation of the stoppers 23. In this way, the retractable end 32 blocks the stoppers 23, limits the movement of the stoppers 23, and further limits the rotation of the screw rod 22. When the screw rod 22 is restricted from rotating, the support member 10 is also restricted from moving up and down, thereby achieving the stability of the support member 10.

[0060] In order to allow the retractable end 32 to extend into the interval between the stoppers 23, generally, the interval width between adjacent stoppers 23 is greater than the width of the retractable end 32. Therefore, after the retractable end 32 extends into the interval between adjacent stoppers 23, there is still a certain amount of space, and the screw rod 22 has a certain amount of rotation, which causes the tray to shake. In order to further improve the stability of the support 10, the number of stoppers 23 can be increased, and the number of intervals can be increased, the width of the intervals can be reduced, and the allowable extension position of the retractable end 32 can be increased to reduce the redundant space after the retractable end 32 extends into the interval.

[0061] In some embodiments, the frame 50 includes a first beam 55 and a second beam 56 , one end of the screw rod 22 is connected to the first beam 55 , and the other end is connected to the second beam 56 , and the stopper 23 is disposed at one end of the screw rod 22 close to the second beam 56 .

[0062] Please combine Figure 1 and Figure 2 In a specific embodiment, the first crossbeam 55 is located at the bottom of the frame 50, the second crossbeam 56 is arranged at the top of the frame 50, one end of the screw rod 22 is rotatably connected to the first crossbeam 55 through the second gear of the first driving member 21, and the other end is rotatably connected to the second crossbeam 56 through the supporting member 10. Specifically, the screw rod 22 can be connected to the second crossbeam 56 through a bearing. Exemplarily, the telescopic mechanism also includes a second driving member 33, the output end of the second driving member 33 is connected to the telescopic end 32, and the second driving member 33 is fixed to the second crossbeam 56 through a mounting plate. In this way, the second driving member 33 can drive the telescopic end 32 to switch between the extended state and the retracted state.

[0063] Optionally, the lifting mechanism 20 further includes one or more guide members 24, which are used to limit the moving direction of the support member 10. The guide members 24 extend along the first direction, and the guide members 24 are all disposed through the support member 10. In this way, when the guide members 24 are fixed, the support member 10 is restricted to move along the extending direction of the guide members 24. When the extending direction of the guide members 24 is the first direction where the screw rod 22 is located, the stability of the support member 10 during movement can be further improved to prevent it from shaking. Optionally, the two ends of the guide member 24 are respectively fixed to the first crossbeam 55 and the second crossbeam 56.

[0064] See also Figure 1 and Figure 7 In some embodiments, the battery cell loading device also includes a first fixing mechanism 53 and a second fixing mechanism 54, which are respectively arranged on a second cross beam 56 on opposite sides of the frame 50, and the first fixing mechanism 53 and the second fixing mechanism 54 can move relative to each other to fix the battery cell tray.

[0065] Optionally, the first fixing mechanism 53 and the second fixing mechanism 54 can be configured near the top of the frame 50. When the battery cell tray 40 rises to a preset position, the first fixing mechanism 53 and the second fixing mechanism 54 fix the topmost battery cell tray 40, thereby ensuring the stability of the topmost battery cell tray 40 when the robot arm grasps it, and at the same time improving the grasping accuracy of the robot arm.

[0066] Specifically, Figure 7 and Figure 8 As shown, Figure 8 Shows Figure 1 Enlarged view of the middle C area. The first fixing mechanism 53 includes a first cylinder 531 and a first clamping plate 532, and the second fixing mechanism 54 includes a second cylinder 541 and a second clamping plate 542. The first cylinder 531 and the second cylinder 541 are respectively fixed to the corresponding second crossbeam 56. The output end of the first cylinder 531 is connected to the first clamping plate 532, and the output end of the second cylinder 541 is connected to the second clamping plate 542. The first cylinder 531 can drive the first clamping plate 532 to move, and the second cylinder 541 can drive the second clamping plate 542 to move, so that the first clamping plate 532 and the second clamping plate 542 can move relative to each other, and then the first clamping plate 532 and the second clamping plate 542 can clamp the battery tray 40, so as to fix the battery tray 40. The first fixing mechanism 53 may also include a first clamping plate guide 533, which is connected between the first cylinder 531 and the first clamping plate 532 to guide the moving direction of the first clamping plate 532, and the second fixing mechanism 54 may also include a second clamping plate guide 543, which is connected between the second cylinder 541 and the second clamping plate 542 to guide the moving direction of the second clamping plate 542, thereby ensuring that the first clamping plate 532 and the second clamping plate 542 effectively fix the battery cell tray 40.

[0067] In order to facilitate the movement of the cell tray 40 and the cells carried thereon, in some embodiments, the cell loading device further includes a first conveying assembly 51 for loading the cell tray 40; the first conveying assembly 51 is disposed on the support 10, and the first conveying assembly 51 can move synchronously with the support 10. For example, in actual production, an operator can transport a material transporting trolley loaded with the cell tray 40 to the first conveying assembly 51, and manually transfer the cell tray 40 on the material transporting trolley to the first conveying assembly 51.

[0068] Usually, each battery cell tray 40 carries a large number of battery cells, and the weight of each battery cell tray 40 is very heavy. The weight after stacking will increase several times. For example, in some embodiments, the first conveying component 51 can also be connected to an automatic handling system, such as being able to accept automatic feeding from an AGV (Automated Guided Vehicle) cart, further saving manpower.

[0069] Alternatively, in some embodiments, the battery cell loading device also includes a second conveying component 52, and the first conveying component 51 can be moved adjacent to the second conveying component 52 to receive the battery cell tray on the second conveying component 52. Turning on the second conveying component 52 can automatically transfer the stacked battery cell trays 40 to the first conveying component 51 to complete the loading.

[0070] In some embodiments, the battery cell loading device also includes a position sensor and a controller. The position sensor is used to detect the position of the battery cell tray 40. The controller is electrically connected to the position sensor and can control the retractable end 32 of the retractable mechanism 30 to switch between an extended state and a retracted state according to the detection result of the position sensor.

[0071] See also Fig. 9 , Fig. 9 Schematic diagram of the controller controlling the first drive member and the second drive member in one embodiment. When the lifting mechanism 20 includes a screw rod 22 and a first drive member 21, the controller 7 can be connected to the first drive member 21 for communication, so as to control the rotation of the screw rod 22 and the rotation direction through the first drive member 21. When the telescopic mechanism 30 includes a second drive member 33, the controller 7 can be connected to the second drive member 33 for communication, so as to control whether the telescopic end 32 is in an extended state or a retracted state.

[0072] The controller 7 is configured to, while sending a start command to the screw rod 22 to the first drive member 21, send a retraction command to the second drive member 33 to release the movement restriction of the telescopic mechanism 30 on the lifting mechanism 20; and, while sending a stop command to the first drive member 21, send an extension command to the telescopic mechanism 30 to restrict the movement of the lifting mechanism 20.

[0073] The position sensor 8 is used to detect the position of the battery cell or the battery cell tray 40. Through the above setting, the controller 7 is electrically connected to the position sensor 8, so that the controller 7 can obtain the battery cell position detected by the position sensor 8, and then control the start and stop of the lifting mechanism 20 based on the position of the battery cell, as well as control the extension and retraction of the retractable end 32, which can improve accuracy.

[0074] The controller 7 controls the first driving member 21 to start, and the second driving member 33 drives the retractable end 32 to retract, releasing the restriction on the block, so that the screw rod 22 can rotate to drive the battery cell to rise, so that the battery cell at the top layer moves to a position convenient for the robot arm to pick up. When the battery cell at the top layer moves to a suitable position, the controller 7 controls the first driving member 21 to stop, and the second driving member 33 drives the retractable end 32 to extend, so that the retractable end 32 stops the stop block, preventing the screw rod 22 from reversing and causing the battery cell to fall, which can ensure the stability of the battery cell moving upward and reduce safety hazards.
