[0046] Reference Figures 1 to 3 , an embodiment of the present invention provides a battery cell transfer device, the battery cell transfer device comprising:
[0047] A first conveying mechanism 1, wherein the input end of the first conveying mechanism 1 is connected to a first feeding station, and the output end of the first conveying mechanism 1 is provided with a receiving station;
[0048] The turning mechanism 2 is located below the material receiving station, the rotating shaft of the turning mechanism 2 is arranged horizontally, and the turning mechanism 2 is provided with an accommodating cavity 61;
[0049] A first driving device 3 is provided on the turning mechanism 2;
[0050] a baffle 4 connected to the first driving device 3;
[0051] The first conveying mechanism 1 is used to transport the battery cell assembly from the first feeding station to the receiving station; the flipping mechanism 2 is used to flip the accommodating cavity 61 to face the receiving station, so that the battery cell assembly at the receiving station can be received by the accommodating cavity 61; and the flipping mechanism 2 is used to flip the accommodating cavity 61 to face away from the receiving station, so that the battery cell assembly in the accommodating cavity 61 falls to the unloading station;
[0052] The first driving device 3 is used to drive the baffle 4 to cover the accommodating cavity 61 .
[0053] In this embodiment, the battery cell assembly may specifically include a battery cell body formed by stacking positive and negative electrode sheets and a material box for accommodating the battery cell body. The first conveying mechanism 1 may include a linear drive device and corresponding clamping devices. The flipping mechanism 2 may include a stepping rotary drive device, and its rotation angle has a mapping relationship with the number of pulse signals input thereto; preferably, the rated number of pulses can be set to the number of pulses corresponding to half a circle (180°) of rotation of the stepping rotary drive device, so that the stepping rotary drive device can be driven to intermittently switch between a first angle position (i.e., the accommodating cavity 61 is vertically facing upward and facing the material receiving station) and a second angle position (i.e., the accommodating cavity 61 is vertically facing downward and facing the material discharging station); wherein, the accommodating cavity 61 can be a cavity structure directly opened on the flipping mechanism 2, or it can refer to the inner cavity of the box body component externally connected to the flipping mechanism 2, which is not limited here; the contour of the accommodating cavity 61 corresponds to the setting of the battery cell assembly, and can be equal to or slightly larger than the battery cell assembly, so as to form a limiting effect on the battery cell assembly in the accommodating cavity 61 on a plane parallel to the rotation axis of the flipping mechanism 2.
[0054] The first driving device 3 can be a linear driving device or a rotational driving device, which is used to drive the baffle 4 to cover the accommodating cavity 61 by linear sliding or flipping, so that the accommodating cavity 61 becomes a closed chamber, thereby forming a limiting effect on the battery cell assembly in the accommodating cavity 61 in the direction perpendicular to the rotation axis of the flipping mechanism 2.
[0055] Testing and research have revealed that the loosening of the positive and negative electrode sheets within soft-pack battery cells is caused by prolonged localized stress during vertical transfer, which can easily damage the positive and negative electrode sheets. Based on this finding, this embodiment incorporates a flipping mechanism 2 to allow simultaneous flipping of the cell assembly during transfer between two stations with a height difference, thus preventing damage to the cell assembly due to localized stress. During the specific implementation process, the linear drive device of the first conveying mechanism 1 can drive the clamping device to clamp the battery cell assembly at the first feeding station and move the battery cell assembly horizontally to the receiving station; at this time, the battery cell assembly is located above the accommodating cavity 61, and the clamping device can loosen the battery cell assembly to allow the battery cell assembly to enter the accommodating cavity 61 (at this time, the first surface of the battery cell assembly is facing upward); then the first drive device 3 drives the baffle 4 to cover the accommodating cavity 61, so that the battery cell assembly in the accommodating cavity 61 has no degree of freedom; thereafter, the flipping mechanism 2 can drive the accommodating cavity 61 to rotate downward to be opposite to the discharge station below, and finally the first drive device 3 drives the baffle 4 to open, so that the battery cell assembly in the accommodating cavity 61 falls to the discharge station (at this time, the second surface of the battery cell assembly is facing upward, and the second surface is opposite to the first surface). In this way, the flipping operation of the battery cell assembly and the conveying and transfer operation between the first feeding station and the discharge station with a height difference are simultaneously realized while ensuring the structural stability of the battery cell assembly. Among them, the first conveying mechanism 1 moves to the first feeding station again to convey the next battery cell assembly after placing the above-mentioned battery cell assembly in the accommodating cavity 61; the flipping mechanism 2 also drives the accommodating cavity 61 to rotate upward to be opposite to the receiving station after completing the transfer and transportation of the above-mentioned battery cell assembly, so as to receive the next battery cell assembly conveyed by the first conveying mechanism 1, and this cycle is repeated to realize batch transportation of battery cell assemblies.
[0056] As can be seen from the above working process, this embodiment separates the horizontal movement and flipping movement of the battery cell assembly by setting up a first conveying mechanism 1 and a flipping mechanism 2, and provides a baffle 4 that can be driven to cover by the first driving device 3 to form a targeted limiting protection function for the battery cell assembly during the flipping movement on the flipping mechanism 2. While avoiding the battery cell assembly from being damaged due to local force during the transfer process in the height direction through the flipping movement, it also avoids the battery cell assembly from being loosened and damaged during the flipping process. Under the premise of ensuring the structural stability of the battery cell assembly, the flipping operation of the battery cell assembly and the conveying and transfer operation between the first feeding station and the discharging station with a height difference are realized at the same time; and since the horizontal conveying and flipping movement of the battery cell assembly are carried out by two mechanisms, the first conveying mechanism 1 can convey the next battery cell assembly when the previous battery cell assembly is performing a flipping movement. Through the cooperation of the first conveying mechanism 1 and the flipping mechanism 2, the action time of the battery cell assembly is reasonably allocated, and there is no need to wait for the entire conveying and flipping process to be completed before repeating the above conveying and flipping process, thereby improving the batch transfer efficiency of the battery cell assembly.
[0057] Optionally, refer to Figures 1 to 3 , the battery cell transfer device also includes a second conveying mechanism 5; wherein:
[0058] The second conveying mechanism 5 is spaced apart from the first conveying mechanism 1, and the turning mechanism 2 is located between the first conveying mechanism 1 and the second conveying mechanism 5; the input end of the second conveying mechanism 5 is used to connect to the second feeding station, and the output end of the second conveying mechanism 5 is set at the receiving station;
[0059] The second conveying mechanism 5 is used to transport the battery cell components from the second feeding station to the receiving station.
[0060] Optionally, refer to Figures 1 to 3 There are two accommodating cavities 61, and the two accommodating cavities 61 are evenly distributed along the rotation circumference of the flip mechanism 2;
[0061] The flipping mechanism 2 is used to flip so that any one of the accommodating cavities 61 faces the material receiving station, and the other accommodating cavities 61 faces the material discharging station.
[0062] In this embodiment, schematically, when one of the accommodating concave cavities 61 is facing the upper receiving station, the other accommodating concave cavity 61 is facing the lower unloading station. In this way, when the lower accommodating concave cavity 61 is performing the unloading operation (i.e., the first driving device 3 drives the baffle 4 to open so that the battery cell assembly falls to the unloading station), the upper accommodating concave cavity 61 can simultaneously perform the receiving operation (i.e., the first conveying mechanism 1 conveys the battery cell assembly of the first feeding station to the receiving station and places it in the accommodating concave cavity 61, and the first driving device 3 drives the baffle 4 to close to form a limit for the battery cell assembly); when the flipping mechanism 2 rotates 90°, the accommodating concave cavity 61 that has completed unloading moves to the upper receiving station, and the accommodating concave cavity 61 that has completed receiving moves to the lower unloading station. At this time, the first conveying mechanism 1 has returned to the first feeding station to wait for the next battery cell assembly to be conveyed, and the second conveying mechanism 5 has already conveyed the second feeding station. When the battery cell assembly at the feeding station is transported to the receiving station, the accommodating cavity 61 located at the feeding station can perform the receiving operation, and the accommodating cavity 61 located at the discharging station can perform the unloading operation at the same time; when the flipping mechanism 2 rotates 90° again, the accommodating cavity 61 that has completed unloading moves to the upper feeding station, and the accommodating cavity 61 that has completed the receiving moves to the lower discharging station. At this time, the second conveying mechanism 5 has returned to the second feeding station to wait for the next battery cell assembly to be transported, and the first conveying mechanism 1 has transported the battery cell assembly of the first feeding station to the feeding station. At this time, the accommodating cavity 61 located at the feeding station can perform the receiving operation, and the accommodating cavity 61 located at the discharging station can perform the unloading operation, and this cycle is repeated.
[0063] Through the cooperation of the above-mentioned first conveying mechanism 1, the second conveying mechanism 5 and the flipping mechanism 2, the waiting time caused by the inconsistency between the cycle of conveying the battery cell components from the feeding station to the receiving station and the cycle of the battery cell component flipping operation can be compressed, thereby further improving the batch transfer efficiency of the battery cell components.
[0064] Optionally, refer to Figures 1 to 3 The first conveying mechanism 1 includes a first multi-axis driving device 11 and a first clamping jaw 12; the first multi-axis driving device 11 is arranged on one side of the flipping mechanism 2, and the first clamping jaw 12 is connected to the first multi-axis driving device 11; the first multi-axis driving device 11 is used to drive the first clamping jaw 12 to move in a straight line along the first horizontal path and / or the first vertical path, and the first clamping jaw 12 is used to clamp the battery core assembly.
[0065] Optionally, refer to Figures 1 to 3 The second conveying mechanism 5 includes a second multi-axis driving device 51 and a second clamping jaw 52; the second multi-axis driving device 51 is arranged on the other side of the flipping mechanism 2, and the second clamping jaw 52 is connected to the second multi-axis driving device 51; the second multi-axis driving device 51 is used to drive the second clamping jaw 52 to move in a straight line along the second horizontal path and / or the second vertical path, and the second clamping jaw 52 is used to clamp the battery cell assembly.
[0066] Illustratively, the first multi-axis drive device 11 and the second multi-axis drive device 51 both have a horizontal moving axis and a vertical moving axis. When there is a height difference between the first feeding station, the second feeding station and the receiving station, it is easier to drive the battery cell assembly to the preset receiving station so that the battery cell assembly can be more accurately placed in the accommodating cavity 61.
[0067] Optionally, refer to Figures 1 to 3 The flip mechanism 2 is detachably connected to a housing shell 6, a housing cavity 61 is provided on the housing shell 6, and the first driving device 3 is provided on the housing shell 6;
[0068] A first positioning pin (not shown in the figure) is provided on the bottom wall of the accommodating cavity 61 . The first positioning pin is used to cooperate with the first positioning hole on the battery cell assembly.
[0069] In this embodiment, the housing 6 can be disassembled and replaced with different sized housings to accommodate different cell assemblies, thereby improving the applicability of the device. The provision of a first positioning pin serves to position the cell assembly when it is placed in the accommodating cavity 61 and to limit the cell assembly within the accommodating cavity 61 on a plane parallel to the rotation axis of the flipping mechanism 2, thereby further improving the stability of the cell assembly within the accommodating cavity 61 and preventing damage to the cell assembly during flipping.
[0070] Optionally, refer to Figures 1 to 3 The cell transfer device further includes a second driving device 63 and a second positioning pin 64; wherein:
[0071] The second driving device 63 is provided on the accommodating shell 6, the second positioning pin 64 is connected to the second driving device 63, and the side wall of the accommodating shell 6 is provided with a first avoidance through hole (not shown in the figure);
[0072] The second driving device 63 is used to drive the second positioning pin 64 to pass through the first avoidance through hole, so that the second positioning pin 64 abuts against the side wall of the battery cell assembly in the accommodating cavity 61 .
[0073] By providing a second positioning pin 64 that can be driven by the second driving device 63, the displacement of the battery cell assembly within the accommodating cavity 61 can be further limited, thereby further improving the stability of the battery cell assembly within the accommodating cavity 61 and preventing the battery cell assembly from colliding with the side wall of the accommodating cavity 61 during the flipping process and being damaged. The second positioning pin 64 abuts the side wall of the battery cell assembly. Specifically, the second positioning pin 64 can be directly pressed against the side wall of the battery cell assembly, or the second positioning pin 64 can be engaged with another positioning hole on the side wall of the battery cell assembly, which is not limited here.
[0074] Optionally, refer to Figures 1 to 3, a third driving device 65 is provided on the accommodating shell 6, and the third driving device 65 has an abutting portion; a second avoidance through hole (not shown in the figure) is opened on the bottom wall of the accommodating shell 6;
[0075] The third driving device 65 is used to drive the abutting portion to penetrate the second avoidance through hole, so as to push the battery cell assembly in the accommodating cavity 61 through the abutting portion, so that the battery cell assembly abuts against the baffle 4 covering the accommodating cavity 61 .
[0076] The third driving device 65 can be a linear cylinder, and the abutting portion can be the piston end of the linear cylinder. The abutting and limiting effect of the abutting portion can keep the battery cell assembly close to the baffle 4, preventing the battery cell assembly from shaking in the accommodating cavity 61 due to the gap during the flipping process, which could cause collision damage to the battery cell assembly.
[0077] Optionally, refer to Figures 1 to 3 , a suction assembly 62 is fixed on the accommodating shell 6;
[0078] The battery cell assembly accommodated in the accommodating cavity 61 has a pole ear portion located outside the accommodating cavity 61 , and the suction assembly 62 is used to suction and fix the pole ear portion.
[0079] The provision of the suction assembly 62 prevents the thin, fragile tabs exposed in the accommodating cavity 61 from becoming loose and damaged due to excessive shaking during the flipping process, thereby more comprehensively protecting the overall structural stability of the battery cell assembly during the flipping process. The suction assembly 62 can be a suction cup or various devices that utilize air pressure for suction, which are not listed here.
[0080] Optionally, refer to Figures 1 to 3 , the battery cell transfer device also includes a lifting drive device 7; wherein:
[0081] The turnover mechanism 2 is disposed on a lifting drive device 7 ; the lifting drive device 7 is used to drive the turnover mechanism 2 to perform a lifting motion so that the accommodating cavity 61 approaches or moves away from the discharge station.
[0082] By providing the lifting drive device 7, it is easier to control the vertical distance between the accommodating cavity 61 and the discharge station. Specifically, if the accommodating cavity 61 is still at a large height difference from the discharge station after being rotated downward by the turning mechanism 2, the lifting drive device 7 can be used to drive the turning mechanism 2 downward to bring the accommodating cavity 61 closer to the discharge station. When the vertical distance between the accommodating cavity 61 and the discharge station is appropriate, the first drive device 3 can be used to drive the baffle 4 to open to perform the unloading operation, thereby preventing damage to the battery cell assembly due to the battery cell assembly falling too high.
[0083] Optionally, refer to Figures 1 to 3The first driving device 3 includes a double-shaft motor 31, a first screw rod 32 and a second screw rod 33, and the baffle 4 includes a first plate body 41 and a second plate body 42; wherein:
[0084] The dual-output shaft motor 31 is disposed on the flip mechanism 2, with the accommodating cavity 61 facing away from the dual-output shaft motor 31; one end of the first screw rod 32 is connected to the first output end of the dual-output shaft motor 31, and the other end of the first screw rod 32 is connected to the first plate 41; one end of the second screw rod 33 is connected to the second output end of the dual-output shaft motor 31, and the other end of the second screw rod 33 is connected to the second plate 42;
[0085] The dual-shaft motor 31 is used to drive the first plate 41 and the second plate 42 to move linearly toward each other, so that the first plate 41 and the second plate 42 cover the accommodating cavity 61 .
[0086] The first plate 41 and the second plate 42 may each include a connecting portion and a covering portion that are interconnected to form an L-shape as shown, wherein the connecting portion is used to connect the first screw rod 32 and the second screw rod 33, and the covering portion is flat and parallel to the plane where the opening of the accommodating cavity 61 is located. Driven by the dual-output shaft motor 31, the first plate 41 and the second plate 42 can be attached to the plane where the opening of the accommodating cavity 61 is located and simultaneously slide linearly toward each other to cover the accommodating cavity 61 or open from the accommodating cavity 61. Compared with the flip-opening method, this movable opening and closing method of the baffle 4 can save more space in the vertical direction, avoid interference between the baffle 4 and the first clamping jaw 12 and the second clamping jaw 52 after opening during the material receiving process, and avoid interference between the baffle 4 and the discharge station after opening during the unloading process.
[0087] It should be noted that other contents of the battery cell transfer device disclosed in the present invention can be found in the prior art and will not be described in detail here.
