[0001] This application relates to the field of battery technology, and more specifically, to a cell transfer mechanism and a cell loading device. Background Technology

[0002] During the battery cell loading process, the cells need to be gripped and transferred. Currently, related technologies typically employ manual operation or robotic arms for gripping the cells. However, these methods can only grip a limited number of cells at a time, resulting in low efficiency, low automation, and the use of robotic arms can easily lead to cell deformation.

[0009] Furthermore, the top material component includes a connecting seat and a plurality of top material columns spaced apart on the connecting seat along the first direction.

[0010] Furthermore, the interval between two adjacent top material columns is equal to the interval between two adjacent battery cell storage slots.

[0021] Figures 1 to 8 This invention illustrates a battery cell loading device according to an embodiment of the present invention. It can automatically and accurately perform the battery cell loading process, reducing manual operation steps and improving work efficiency. The battery cell loading device includes a tray conveying mechanism 10, a battery cell transfer mechanism 20, a pipeline guiding mechanism 30, and a control mechanism (not shown in the figure). The control mechanism is electrically connected to both the tray conveying mechanism 10 and the battery cell transfer mechanism 20, and is used to control the normal operation of the battery cell loading device. The tray conveying mechanism 10 is used to convey a tray 2 containing battery cells 3. The battery cell transfer mechanism 20 is used to grab the battery cells 3 from the tray 2 for the next process. The pipeline guiding mechanism 30 is used to lay conduits and wires, improving the orderliness of the pipelines on the device.

[0022] Specifically, such as Figures 1 to 4 As shown, the tray conveying mechanism 10, the cell transfer mechanism 20, and the pipeline guiding mechanism 30 are respectively arranged on the frame 40. The tray conveying mechanism 10 is generally longitudinally elongated, extending along the second direction X. The tray conveying mechanism 10 includes a platform 11 and at least one conveying component. The platform 11 is generally located at one end of the conveying component along the second direction X, and is used to place an empty tray 2. The conveying component is used to convey the tray 2 containing the cell 3 along the second direction X towards the platform 11. The cell transfer mechanism 20 is generally located along the second direction X at the position opposite to the conveying component and the platform 11, and is at least partially located vertically above the tray conveying mechanism 10, for grabbing the cell 3 in the tray 2 and transferring it.

[0023] We define the vertical direction as the third direction Z, and define the first direction Y. The second direction X, the first direction Y, and the third direction Z are all mutually perpendicular.

[0024] By setting up a material tray conveying mechanism 10, this application eliminates the need for operators to manually move the material tray 2 filled with battery cells 3 to the battery cell transfer mechanism 20, reducing the workload of operators, avoiding problems such as inaccurate placement caused by manual handling, and ensuring operational efficiency.

[0025] like Figures 3 to 6 As shown, in some embodiments, the tray conveying mechanism 10 may include a platform 11, a first conveying component 12, and a second conveying component 13. The first conveying component 12 is disposed at one end of the platform 11 along a second direction X, and is used to convey a tray 2 filled with battery cells 3. The second conveying component 13 is at least partially disposed between the first conveying component 12 and the platform 11, and is used to convey the tray 2 between the first conveying component 12 and the platform 11 in a predetermined stepwise manner. The battery cell gripping component 22 of the battery cell transfer mechanism 20 corresponds approximately along the second direction X to the end of the platform 11 near the second conveying component 13.

[0026] During the cell loading process, the support member 133 in the second conveying component 13 can be moved to the first conveying component 12 to receive the material tray 2 conveyed on the first conveying component 12.

[0027] Furthermore, the support member 133 can approach the platform 11 in a preset step along the second direction X to gradually transport the tray 2 to the platform 11. During this process, each row of battery cells 3 in the tray 2 is grabbed and transferred by the battery cell transfer mechanism 20.

[0028] Furthermore, after all the battery cells 3 in the corresponding tray 2 on the second conveying component 13 are grabbed and transferred by the battery cell transfer mechanism 20, the support member 133 of the second conveying component 13 moves to the first conveying component 12 again to receive the tray 2 conveyed by the first conveying component 12, and so on.

[0029] It should be noted that this preset step can be flexibly set according to the arrangement of the battery cells 3 in the material tray 2, and is not specifically limited here. For example Figure 9 As shown, when the tray 2 is arranged in a matrix with multiple receiving positions 201 for receiving battery cells 3, the length of the preset step can be equal to the distance between two adjacent rows of receiving positions 201 along the second direction X in the tray 2.

[0030] Thus, after the cell transfer mechanism 20 finishes grabbing and transferring a row of cells 3 in the tray 2, the second conveying component 13 moves forward one step in the second direction X toward the platform 11 at a preset pace, which can ensure that the next row of cells 3 in the tray 2 corresponds to the cell transfer mechanism 20, thereby ensuring that the cell transfer mechanism 20 continues to grab the next row of cells 3 accurately, and achieving the accuracy of cell grabbing in the second direction X.

[0031] like Figures 3 to 5 As shown, in some embodiments, the platform 11 is mounted on the frame 40 and includes a pallet 111, at least one limiting component 112, and at least one positioning element 113. The pallet 111 is perpendicular to the third direction Z and abuts against the conveying component to carry the tray 2. The limiting component 112 is mounted on the pallet 111 and limits the tray 2 in the first direction Y and the third direction Z, respectively. The plane containing the limiting component 112 and the pallet 111 defines a tray conveying channel 110, which extends along the second direction X. The tray 2 can only move along the second direction X within the tray conveying channel 110. The positioning element 113 extends at least partially telescopically into the tray conveying channel 110 to restrict the movement of the tray 2 within the tray conveying channel 110.

[0032] Specifically, the pallet 111 is generally rectangular in shape. The first conveying component 12 and the second conveying component 13 are both located at the same end of the pallet 111, and part of the structure of the second conveying component 13 can be located between the first conveying component 12 and the pallet 111 to realize the transfer of the material tray 2 between the two. The pallet 111 may be provided with a clearance window 1111 at the end near the conveying component along the second direction X to provide clearance for the second conveying component 13.

[0033] The limiting component 112 is connected to the two opposite sides of the pallet plate 111 along the first direction Y. The positioning member 113 is disposed on the limiting component 112 and is at least partially telescopically inserted through the limiting component 112 to extend into the pallet conveying channel 110.

[0034] The positioning element 113 extends into the material tray conveying channel 110 when the cell transfer mechanism 20 grips the cell 3 in the material tray 2, thereby restricting the movement of the material tray 2 along the second direction X. Thus, during the process of the cell transfer mechanism 20 gripping the cell 3, even if the material tray 2 is subjected to a force along the second direction X due to external collisions or other reasons, the material tray 2 will be relatively positioned in the second direction X under the action of the positioning element 113, avoiding affecting the gripping of the cell 3 by the cell transfer mechanism 20, and further ensuring the accuracy of cell gripping in the second direction X.

[0035] By setting the limiting component 112, it can be ensured that the position of the material tray 2 is relatively fixed in the first direction Y and the third direction Z during the conveying process on the material tray conveying mechanism 10, and it can only be moved along the second direction X. Therefore, it can be ensured that when it moves to the cell transfer mechanism 20, the cell transfer mechanism 20 is precisely aligned with the cell 3 inside it in the first direction Y and the third direction Z, thereby ensuring that the cell transfer mechanism 20 accurately grasps the same row of cells 3, and realizing the accuracy of cell grasping in the first direction Y and the third direction Z.

[0036] In this way, in conjunction with the preset steps of the second conveying component 13, the cell transfer mechanism 20 can accurately align and grasp the cell 3 inside the tray 2 in the second direction X, the first direction Y, and the third direction Z. That is, it ensures the accurate grasping of the cell 3 by the cell transfer mechanism 20.

[0037] like Figure 5 As shown, in some embodiments, the limiting component 112 may include at least two first limiting members 1121 and at least one second limiting member 1122. The first limiting members 1121 are plate-shaped, and at least one first limiting member 1121 is respectively provided on opposite sides of the pallet plate 111 along the first direction Y to limit the material tray 2 in the first direction Y. The first limiting member 1121 is disposed on the pallet plate 111 and is at least partially spaced from the plane of the pallet plate 111 along the third direction Z to limit the material tray 2 in the third direction Z.

[0038] Thus, during the process of material tray 2 being conveyed and battery cell 3 being grasped, even if material tray 2 is subjected to force along the first direction Y or the third direction Z due to factors such as vibration or external force, it will maintain relative positioning under the action of the first limiting member 1121 and the second limiting member 1122, so as to avoid affecting the grasping of battery cell 3 by battery cell transfer mechanism 20.

[0039] Specifically, there are two first limiting members 1121. Each first limiting member 1121 is generally a longitudinally elongated rectangular plate extending along the second direction X, partially corresponding to the pallet plate 111, and partially corresponding to the portions of the first conveying assembly 12 and the second conveying assembly 13 near the end of the pallet plate 111. In this way, when the tray 2 is moved between the several components, it can always be in a positioned state along the first direction Y.

[0040] There are two second limiting members 1122, which are correspondingly disposed on the two first limiting members 1121, and their positions along the second direction X correspond to the cell transfer mechanism 20. Each second limiting member 1121 is generally L-shaped plate structure, with its vertical wall disposed on the first limiting member 1121, perpendicular to the first direction Y, and its horizontal wall parallel to and spaced above the tray plate 111, perpendicular to the third direction Z.

[0041] See also Figure 9 The side wall of the tray 2 extends upward with at least two limiting posts 202. When the tray 2 is placed on the tray conveying mechanism 10, the at least two limiting posts 202 are located on opposite sides of the tray 2 along the first direction Y.

[0042] The distance between the horizontal wall of the second limiting member 1122 and the plane of the pallet plate 111 along the third direction Y is approximately equal to the distance between the top of the limiting post 202 and the bottom wall of the tray 2. The distance between the ends of the two second limiting members 1122 that are close to each other along the first direction Y is equal to or slightly greater than the distance between the ends of the two limiting posts 202 that are close to each other along the first direction Y.

[0043] Thus, the horizontal wall of the second limiting member 1122 can limit the material tray 2 by limiting the limiting post 202, and also avoid the horizontal wall extending above the receiving position 201 and affecting the cell transfer mechanism 20's gripping of the cell 3.

[0044] It should be noted that the number and length of the first limiting member 1121 and the second limiting member 1122 may be the same or different. For example, when there are two first limiting members 1121, the number of second limiting members 1122 may be set to four, etc.

[0045] In some other embodiments, the second limiting member 1122 may also be longitudinally elongated, extending partially to the position of the first conveying component 12 and the second conveying component 13 near the pallet plate 111.

[0046] In some other embodiments, when there is only one second limiting member 1122, it may also be in the shape of an inverted U-shaped cover, with its two sides connected to two first limiting members 1121 respectively. In this embodiment, the top wall of the second limiting member 1122 may also be provided with a through hole, so that the cell transfer mechanism 20 can extend through the through hole to the receiving position 201 of the material tray 2 to grab the cell 3.

[0047] In some other embodiments, the first limiting member 1121 and the second limiting member 1122 may also be integrally arranged and form a plate structure with an L-shaped cross section. One side wall is used to limit the material tray 2 along the first direction Y, and the top wall is used to limit the material tray 2 along the third direction Z.

[0048] In some other embodiments, the first limiting member 1121 and the second limiting member 1122 may also be integrally configured as an inverted German U-shaped cover plate, covering the tray plate 111.

[0049] In some embodiments, the number of positioning members 113 may be at least two, respectively disposed on two first limiting members 1121.

[0050] Specifically, the positioning member 113 is disposed on the side of the first limiting member 1121 opposite to the material tray conveying channel 110 and is electrically connected to the control mechanism. The positioning member 113 has a telescopic rod that passes through the first limiting member 1121 and extends telescopically into the material tray conveying channel 110.

[0051] Among them, such as Figure 3 As shown, there are at least two positioning members 113, whose positions in the second direction X roughly correspond to those of the cell transfer mechanism 20. When the cell transfer mechanism 20 grips the cell 3, the positioning members 113 can extend their piston rods into the tray transfer space 100 to abut against the tray 2. The telescopic rods of the two positioning members 113 located on opposite sides of the tray 2 along the first direction Y extend into the tray transfer channel 110 to press the tray 2, thereby clamping the tray 2. This enables the positioning of the tray 2, further ensuring the accuracy of cell gripping in all directions.

[0052] See also Figure 4 and Figure 5 Furthermore, when the number of positioning members 113 is set to multiple, some positioning members 113 may correspond approximately to the cell transfer mechanism 20 in the second direction X, and some positioning members 113 may correspond approximately to the end of the first conveying assembly 12 near the tray plate 111 in the second direction X. In this way, during the process of the cell transfer mechanism 20 gripping the cell 3, the multiple positioning members 113 can respectively position the tray 2 where the gripped cell 3 is located and the tray 2 conveyed on the first conveying assembly 12.

[0053] Thus, even when the first conveying component 12 is picking up the battery cell 3, it still performs the tray conveying operation. The tray 2 it conveys will slide and rub against the first conveying component 12 under the positioning action of the positioning component 113, and remain relatively stationary with the pallet plate 111 in the second direction X, so as to avoid affecting the battery cell transfer mechanism 20 to pick up the battery cell 3 in the tray 2 on the second conveying component 13.

[0054] That is, by setting some positioning components 113 to correspond to the material tray 2 conveyed on the first conveying component 12, the positioning effect of the material tray 2 in the second direction X can be further improved, and the accuracy of the battery cell grabbing in the second direction X can be further ensured.

[0055] Of course, when there are multiple positioning elements 113, the positioning elements 113 can be evenly spaced along the second direction X on the material tray conveying mechanism 10 so that each positioning element 113 corresponds to positioning one or at least two material trays 2, so as to further improve the positioning effect of the material trays 2.

[0056] It should be noted that the positioning component 113 can specifically adopt a structure such as a cylinder, and the piston rod of the cylinder can be regarded as the telescopic rod of the positioning component 113.

[0057] In other embodiments, the positioning member 113 may also be configured as a rib, a baffle plate, or other blocking structure, which is movably mounted on the first limiting member 1121 or the tray plate 111. When it is necessary to limit the movement of a certain tray 2 in the second direction X, the positioning member 113 can be moved so that it protrudes from the front side of the tray 2 in the direction of movement and abuts against the tray 2, thereby achieving the effect of limiting the movement of the tray 2.

[0058] like Figure 3 and Figure 4 As shown, in some embodiments, the first conveying assembly 12 may include a drive motor 121, a transmission rod 123, two first guide rails 122, two sets of conveyor belts 124, and two sets of pulleys (not shown in the figure).

[0059] Both first guide rails 122 extend along the second direction X and are arranged parallel to each other along the first direction Y. Two sets of conveyor belts are respectively set on the two first guide rails 122, and two sets of pulleys are respectively set on the two first guide rails 122. Each set of conveyor belts is sleeved on each set of pulleys so that it can move by rotating the pulleys to support and convey the material tray 2.

[0060] The transmission rod 123 extends along the first direction Y and is positioned between two first guide rails 122. Both ends are coaxially connected to pulleys on the two first guide rails 122 for synchronous rotation. The drive motor 121 is electrically connected to the control mechanism, and its output shaft is coaxially connected to the transmission rod 123 to drive the transmission rod 123 to rotate, thereby driving the pulleys on the two first guide rails 122 and the conveyor belt 124 mounted on the pulleys.

[0061] Furthermore, such as Figure 3 As shown, each of the two first guide rails 122 is also provided with a stepped surface 1221, and the conveyor belt 124 is provided on the first guide rail 122 on the inner side of the stepped surface 1221. The stepped surface 1221 is used to limit the material tray 2 it transmits along the first direction Y.

[0062] Specifically, the first limiting member 1121 of the limiting component 112 is positioned at the same position as the step surface 1221 in the first direction Y, and the inner surfaces of the two are smoothly transitioned, together realizing the limiting of the material tray 2 by the material tray conveying mechanism 10 in the first direction Y.

[0063] It should be understood that the conveyor belt 124 is located inside the step surface 1221, which can be understood as the two conveyor belts 124 being located between the two step surfaces 1221 along the first direction Y.

[0064] It should be noted that the conveyor belt 124 may specifically adopt a belt structure with a certain friction to improve the stability of the material tray 2 transmission and avoid the material tray 2 and the conveyor belt 124 from easily sliding relative to each other, resulting in ineffective transmission.

[0065] It should be noted that the first transmission component 12 can be implemented using existing synchronous belt transmission structures, which will not be elaborated further here.

[0066] like Figure 6 As shown, in some embodiments, the second conveying assembly 13 may include a third drive structure 131, a support member 133, and at least one vertical drive member 132. The third drive structure 131 and the vertical drive member 132 are electrically connected to a control mechanism. The vertical drive member 132 is disposed on the third drive structure 131, and the third drive structure 131 drives the vertical drive member 132 to move back and forth along the second direction X. The support member 133 is disposed on the vertical drive member 132 and is used to support the material tray 2. The vertical drive member 132 drives the support member 133 to move back and forth along the third direction Z. Thus, the support member 133 can move back and forth in both the second direction X and the third direction Z.

[0067] Specifically, please refer to the following: Figure 3 and Figure 4 The width of the second conveying assembly 13 in the first direction Y can be smaller than the spacing between the two inner sidewalls of the two first guide rails 122 in the first conveying assembly 12 along the first direction Y. In this way, the second conveying assembly 13 can be disposed between the two first guide rails 122 and the tray plate 111 via the frame 40.

[0068] The third drive structure 131 may specifically include a second guide rail 1311 extending along the second direction X, a movable seat 1312 movably disposed on the guide rail, and other structures. The second guide rail 1311 is disposed between the two first guide rails 122 along the first direction Y, and is disposed below the two first guide rails 122. There are two vertical drive members 132, which are spaced apart along the first direction Y on the movable seat 1312 to improve the stability of the support for the support member 133.

[0069] It should be noted that the third drive structure 131 can be implemented using existing drive and guide structures such as a lead screw and nut seat structure, a rodless cylinder structure, or a slide cylinder structure, which will not be elaborated further here. The vertical drive component 132 can be implemented using a cylinder, which will also not be elaborated further here.

[0070] In other embodiments, the number of vertical drive members 132 may be three, four, or more, and they may also be spaced apart along the second direction X on the movable seat 1312.

[0071] like Figure 3 and Figure 6 As shown, in some embodiments, the support member 133 is disposed between the first conveying assembly 12 and the pallet plate 111, and may include a support plate 1331 and at least two support rods 1332. The at least two support rods 1332 are disposed parallel to each other along a first direction Y on the side of the support plate 1331 near the pallet plate 111, and both extend along a second direction X.

[0072] Specifically, the length of the support member 133 in the first direction Y is less than the interval between the two first guide rails 122, so as to facilitate the movement of the support member 133 between the two first guide rails 122 to transfer the material tray 2. The support rod 1332 corresponds to the clearance window 1111 on the pallet plate 111 in the first direction Y, and the interval between the two outermost support rods 1332 in the first direction Y is less than the length of the clearance window 1111 in the first direction Y, so as to facilitate the extension of the support rod 1332 into the clearance window 1111 to realize the transfer of the material tray 2 from the support member 133 to the pallet plate 111.

[0073] The length of the support rod 1332 along the second direction X is approximately equal to the depth of the clearance window 1111 in the second direction X.

[0074] Furthermore, such as Figure 6 and Figure 2 As shown, each support rod 1332 may be provided with a first protrusion 1333 and a second protrusion 1334 at intervals along the second direction X. The interval between the first protrusion 1333 and the second protrusion 1334 is approximately equal to the length of at least one material tray 2 in the second direction X, so as to limit the material tray 2 in the second direction X.

[0075] In some embodiments, the vertical drive member 132 can move back and forth between a first horizontal position, a second horizontal position, and a third horizontal position under the drive of the third drive structure 131. The support member 133 can move back and forth between a first height position and a second height position under the drive of the vertical drive member 132.

[0076] When the vertical drive member 132 is in the first horizontal position, the support member 133 corresponds to the first transmission assembly 12 along the second direction X, and the support rod 1332 is located outside the clearance window 1111.

[0077] When the vertical drive member 132 is in the second horizontal position, the end of the support rod 1332 away from the support plate 1331 along the second direction X corresponds approximately to the cell gripping assembly 22 of the cell transfer mechanism 20 and approximately aligns with the clearance window 1111. In this position, the cell gripping assembly 22 can grip the cell 3 on the support rod 1332 along the second direction X near the end of the tray 2 near the end of the tray 111.

[0078] When the vertical drive member 132 is in the third horizontal position, the support rod 1332 extends into the clearance window 1111, and its end connected to the support plate 1331 roughly corresponds to the cell gripping assembly 22. In this position, the cell gripping assembly 22 can grip the cell 3 on the support rod 1332 along the second direction X near the end of the first conveying assembly 12 in the tray 2 near the end of the first conveying assembly 12.

[0079] When the support member 133 is in the first height position, its top surface is lower than the conveyor belt 124 of the first conveying assembly 12. At this height position, the support member 133 can move along the second direction X to below the conveyor belt 124.

[0080] When the support member 133 is in the second height position, the top surface of the support member 133 is approximately flush with the pallet plate 111 and is positioned above the conveyor belt 124.

[0081] During the specific operation of the battery cell feeding device, the vertical drive component 132 can first drive the support component 133 to move to a first height position, and the third drive structure 131 drives the vertical drive component 132 to move to a first horizontal position. This position is now defined as the material picking position.

[0082] When the support member 133 is in the material-picking position, it corresponds to the first conveying assembly 12 along the second direction X and is positioned between the two first guide rails 122 of the first conveying assembly 12 along the first direction Y. The support rod 1332 is entirely located outside the clearance window 1111, and at least one tray 2 on the first conveying assembly 12 is located near the pallet plate 111 along the second direction X, between the first protrusion 1333 and the second protrusion 1334 along the second direction X. The top surface of the support member 133 is lower than the top surface of the conveyor belt 124 in the third direction Z.

[0083] Furthermore, the vertical drive member 132 can drive the support member 133 to move from a first height position to a second height position along the third direction Z. At this time, the top surface of the support member 133 gradually rises above the conveyor belt 124, so at least one tray 2 located on the conveyor belt 124 near the end of the pallet plate 111 along the second direction X can be lifted by the support member 1332 and confined along the second direction X between the first protrusion 1333 and the second protrusion 1334.

[0084] Furthermore, the third drive structure 131 can drive the vertical drive member 132 and the support member 133 to move from the first horizontal position to the second horizontal position.

[0085] It is now defined that when the support 133 is in the second height position and simultaneously in any horizontal position between the second and third horizontal positions, the support 133 is in the feeding position.

[0086] When the support member 133 is within the feeding position range and in the second horizontal position, in at least one tray 2 supported by the support member 133, the first row of battery cells 3 inside the tray 2 closest to the pallet plate 111 along the second direction X generally corresponds to the battery cell gripping assembly 22 of the battery cell transfer mechanism 20. At this time, the battery cell transfer mechanism 20 can grip and transfer at least some of the battery cells 3 located in the first row.

[0087] Furthermore, after the cell transfer mechanism 20 has grasped and transferred all the cells 3 located in the row, the control mechanism controls the third drive structure 131 to drive the vertical drive member 132 and the support member 133 to move forward one step closer to the pallet plate 111 according to a preset pace. At this time, the second row of cells 3 inside the material tray 2 along the second direction X close to the pallet plate 111 can correspond to the cell grasping component 22 of the cell transfer mechanism 20, and the cell transfer mechanism 20 can grasp and transfer at least some of the cells 3 located in the second row. This process continues until the third drive structure 131 drives the vertical drive member 132 and the support member 133 to gradually advance from the second horizontal position to the third horizontal position within the feeding position range according to a preset pace.

[0088] At this time, the support rod 1332 extends approximately into the clearance window 1111, and the last row of battery cells 3 on the tray 2 of the support rod 1332 corresponds to the battery cell gripping assembly 22 of the battery cell transfer mechanism 20. For example... Figure 1 and Figure 2 As shown, the cell transfer mechanism 20 can grab and transfer the last row of cells 3 located on the support rod 1332, leaving the material tray 2 on the support rod 1332 empty.

[0089] Furthermore, the vertical drive member 132 can drive the support member 133 to descend from the second height position to the first height position along the third direction Z. During this process, such as... Figure 2 As shown, since the pallet plate 111 is located in the first direction Y at the plate portion of the clearance window 1111, it can support the tray 2. Therefore, when the support member 133 descends, the empty tray 2 located on the support rod 1332 can be supported on the pallet plate 111, realizing the transfer of the empty tray 2 from the support member 133 to the pallet plate 111.

[0090] Furthermore, the third drive structure 131 can drive the vertical drive member 132 and the support member 133 to move from the third horizontal position to the first horizontal position along the second direction X.

[0091] Furthermore, the vertical drive 132 drives the support 133 to move upward along the third direction Z from the first height position to the second height position, so as to lift at least one tray 2 on the conveyor belt 124 again. This process is repeated continuously.

[0092] Of course, the above-mentioned specific steps for feeding battery cells are only one specific example. The specific steps can be flexibly adjusted based on the number of material trays 2 on the first conveying component 12 and the number of material trays 2 that the support rod 1332 can support. They will not be elaborated on one by one here.

[0093] It should be noted that when the control mechanism controls the third drive structure 131 to move the vertical drive member 132 and the support member 133 back and forth between the first horizontal position, the second horizontal position, and the third horizontal position, the interval between the second horizontal position and the third horizontal position can be equal to the length of a natural number of material trays 2 in the second direction X. In this way, it can be ensured that the support member 133 moves back and forth between fixed preset points, thereby further ensuring the accuracy of the cell transfer mechanism 20 in grasping the cell 3 in the second direction X.

[0094] In some other embodiments, the tray conveying mechanism 10 may include only a platform 11 and a second conveying component 13, which may include only a third drive structure 131 and a support member 133. During operation, the operator can place the tray 2 containing the battery cells 3 directly onto the support member 133, and the third drive structure 131 drives the support member 133 to move gradually towards the pallet plate 111 at a preset pace.

[0095] like Figures 1 to 4 As shown, in some embodiments, the cell transfer mechanism 20 may include a pushing assembly 21, a cell gripping assembly 22, a first driving structure 23, and a second driving structure 24, all electrically connected to a control mechanism. The pushing assembly 21, cell gripping assembly 22, first driving structure 23, and second driving structure 24 are all electrically connected to the control mechanism. The first driving structure 23 is mounted on a movable seat of the second driving structure 24, and moves back and forth in a direction perpendicular to the third direction Z under the drive of the second driving structure 24. The cell gripping assembly 22 and the pushing assembly 21 are mounted on a movable seat of the first driving structure 23, and move back and forth in a direction perpendicular to the third direction Z under the drive of the first driving structure 23. The cell gripping assembly 22 is used to grip the cell 3 in the tray 2 on the support member 133. The pushing assembly 21 is used to remove the cell 3 gripped by the cell gripping assembly 22 from the cell gripping assembly 22.

[0096] Specifically, the second drive structure 24 is mounted on the frame 40 and extends along the first direction Y to drive the first drive structure 23 and its cell gripping assembly 22 to move along the first direction Y. The first drive structure 23 extends along the third direction Z and is located above the tray conveying mechanism 10. The cell gripping assembly 22 is positioned in the second direction X, approximately corresponding to the end of the tray 111 near the support member 133, and can grip the cell 3 that has moved to the end of the tray 111 near the support member 133.

[0097] The first drive structure 23 can drive the cell gripping assembly 22 and the pushing assembly 21 to move back and forth between a first vertical position, a second vertical position, and a third vertical position. The second drive structure 24 can drive the first drive structure 23 and the cell gripping assembly 22 and the pushing assembly 21 on it to move back and forth between the gripping position and the releasing position.

[0098] Specifically, when the cell gripping assembly 22 is in the gripping position, it corresponds to the tray conveying mechanism 10 in the first direction Y and is located directly above the tray conveying mechanism 10. When the cell gripping assembly 22 is in the unloading position, it is located on one side of the tray conveying mechanism 10 in the first direction Y.

[0099] When the cell gripping assembly 22 is in the first vertical position, it is positioned above the material tray conveying mechanism 10 in the third direction (Z). When the cell gripping assembly 22 is in the second vertical position, its position in the third direction (Z) corresponds to the height of the cell 3 to be gripped in the material tray 2 on the material tray conveying mechanism 10, facilitating the gripping of the cell 3. When the cell gripping assembly 22 is in the third vertical position, its position in the third direction (Z) corresponds to the equipment in the next process of battery production, facilitating the loading of the cell 3 into the equipment of that next process.

[0100] During the actual battery cell loading operation, the battery cell gripping assembly 22, driven by the first drive structure 23 and the second drive structure 24, moves along the first direction Y to the gripping position, and then moves along the third direction to the second vertical position. At this position, the battery cell gripping assembly 22 can grip at least a portion of the battery cells 3 in the material tray 2.

[0101] Furthermore, the first drive structure 23 can drive the cell gripping component 22 to move upward along the third direction Z to the first vertical position.

[0102] Furthermore, the second drive structure 24 can drive the first drive structure 23 and its battery cell gripping assembly 22 to move along the first direction Y to the feeding position.

[0103] Furthermore, the first drive structure 23 drives the cell gripping assembly 22 and the pushing assembly 21 to move from the first vertical position to the third vertical position. At this time, the position of the cell gripping assembly 22 corresponds to the position of the next battery manufacturing process after the cell loading, and the pushing assembly 21 can disassemble the cell 3 gripped by the cell gripping assembly 22 into the equipment of the next process.

[0104] Furthermore, the second drive structure 24 and the first drive structure 23 can cooperate to drive the cell gripping component 22 and the pushing component 21 from the feeding position and the third vertical position back to the gripping position and the second vertical position. The cell gripping component 22 can then grip the remaining cells 3 in the material tray 2. This process is repeated continuously.

[0105] It should be noted that the third vertical position may be higher than the first vertical position and / or the second vertical position, or it may be equal to or lower than the first vertical position and / or the second vertical position; no specific limitation is made here.

[0106] It should be noted that the extension direction of the second drive structure 24 can be flexibly set based on the position of the next battery manufacturing process after the cell is loaded. Therefore, the second drive structure 24 can also extend in any direction perpendicular to the third direction Z.

[0107] It should be noted that the first drive structure 23 and the second drive structure 24 can be implemented using existing drive and guide structures such as lead screw and nut seat structure, rodless cylinder structure, slide cylinder structure, and synchronous belt transmission mechanism, and are not limited here.

[0108] like Figure 7 As shown, in some embodiments, the cell gripping assembly 22 may include a gripping plate 221. The pushing assembly 21 may include a pushing drive 211 and a pushing member 212.

[0109] The gripping plate 221 is positioned perpendicular to the second direction X, and has multiple battery cell storage slots 2211 on its side facing the first conveying assembly 12 along the second direction X. These slots are evenly spaced along the first direction Y. Each battery cell storage slot 2211 has at least one magnetic attractor 222 on its wall for magnetically attracting the battery cell 3, thus confining the battery cell 3 within the slot 2211.

[0110] The pusher drive 211 is mounted on the movable seat of the first drive structure 23 and electrically connected to the control mechanism. It is used to drive the pusher 212 to be movably positioned along the third direction Z under the drive of the control mechanism. The pusher 212 is positioned along the second direction X on the side of the gripping plate 221 where the cell storage slot 2211 is provided, and is used to push the cell 3 in the cell storage slot 2211 out of the cell storage slot 2211 by pushing.

[0111] Specifically, both the gripping plate 221 and the pusher 212 are roughly rectangular plates. The shape of the cell receiving groove 2211 on the gripping plate 221 is roughly adapted to the shape of the cylindrical cell 3, and is roughly semi-rectangular or semi-cylindrical. When the cell 3 is housed in the cell receiving groove 2211, a portion of the cell 3 protrudes out of the cell receiving groove 2211 along the second direction X.

[0112] The bottom end of the cell storage slot 2211 extends through the gripping plate 221. A pusher drive 211 is located on the side of the gripping plate 221 furthest from the through side of the cell storage slot 2211 along the third direction Z. A pusher 212 is mounted on the movable part of the pusher drive 211 and is movably attached to the side of the gripping plate 221 where the cell storage slot 2211 is located along the second direction X. Driven by the pusher drive 211, the pusher 212 can move back and forth along the axial direction of the cell storage slot 2211.

[0113] The spacing between two adjacent cell storage slots 2211 on the gripping plate 221 is equal to the spacing between two adjacent receiving positions 201 along the first direction Y, so as to ensure that when the cell gripping assembly 22 is in the gripping position, each cell storage slot 2211 can correspond to a receiving position 201 that is uniformly spaced in a matrix in the material tray 2.

[0114] Furthermore, the number of cell receiving slots 2211 on the gripping plate 221 is equal to the number of a row of receiving positions 201 whose line connecting them is perpendicular to the second direction X, at the placement angle of the tray 2 on the tray conveying mechanism 10. For example, in Figure 7 and Figure 8 In the embodiment shown, there are 16 battery cell storage slots 2211 and 16 rows of storage positions 201.

[0115] In this way, the cell gripping assembly 22 can grip an entire row of cells 3 at once using magnetic attraction, which not only improves the efficiency of the loading operation but also simplifies the movement path of the second drive structure 24 and the first drive structure 23 on the cell gripping assembly 22. By setting the magnetic suction component 222 to grip the cell 3 using magnetic attraction, a relatively uniform attraction force can be provided to the entire side of the cell 3 through magnetic attraction, avoiding local stress concentration and thus effectively solving the problem of cell 3 deformation caused by robotic gripping.

[0116] During the specific battery cell loading process, the third drive structure 131 of the second conveying component 13 can drive the support member 133 to move along the second direction X, so that a row of battery cells 3 along the second direction X near the end of the pallet plate 111 in the material tray 2 near the end of the pallet plate 111 is in the ready-to-grab position.

[0117] Furthermore, after the first drive structure 23 and the second drive structure 24 drive the cell gripping assembly 22 to the second vertical position and the gripping position, the third drive structure 131 can drive the support member 133 to move one step along the second direction X towards the gripping plate 221, so that the row of cells 3 moves from the pre-grip position to the row of cell storage slots 2211 of the gripping plate 221, and is magnetically gripped by the magnetic suction member 222 provided on the slot wall. At this time, the next row of cells 3 in the tray 2 moves to the pre-grip position accordingly.

[0118] Furthermore, driven by the first drive structure 23 and the second drive structure 24, the battery cell gripping assembly 22 transfers the battery cell 3 to the third vertical position and the feeding position. At this time, the pushing drive 211 can drive the pushing component 212 to move downward along the third direction X. Since the pushing component 212 is attached to the side of the gripping plate 221 where the battery cell storage groove 2211 is provided, and the battery cell 3 partially protrudes from the battery cell storage groove 2211, the pushing component 212 can provide downward pushing force to the battery cell 3. When the pushing component 212 moves downward, it can push the battery cell 3 to move downward synchronously along the axial direction of the battery cell storage groove 2211 until the magnetic attraction force provided by the magnetic suction component 222 to the battery cell 3 cannot resist the gravity of the battery cell 3 itself. The battery cell 3 is released from the battery cell storage groove 2211 and falls into the equipment of the next process under the action of gravity, completing the feeding of the battery cell 3.

[0119] Furthermore, the pusher drive 211 can drive the pusher 212 to move upward along the third direction Z, so that the cell storage slot 2211 on the gripping plate 221 is exposed again. The first drive structure 23 and the second drive structure 24 can drive the cell gripping assembly 22 back to the second vertical position and the gripping position.

[0120] Furthermore, the third drive structure 131 drives the support member 133 to move one step closer to the gripping plate 221 along the second direction X, so that the next row of battery cells 3 moves into the battery cell storage slot 2211 of the gripping plate 221 and is magnetically gripped by the magnetic suction member 222 provided on the slot wall. This process is repeated in a continuous cycle.

[0121] It should be noted that the pre-grabbing position is located on the side of the cell storage slot 2211 near the first conveying component 12 in the second direction X, and is spaced from the cell storage slot 2211 by a predetermined step length along the second direction X. Thus, whenever the third drive structure 131 drives the support member 133 to move forward one step along the second direction X by the predetermined step, a row of cells 3 located at the pre-grabbing position can move into the cell storage slot 2211 and magnetically attract with the magnetic suction member 222, completing the grasping process.

[0122] It should be noted that the pusher drive component 211 can be a cylinder. By setting its piston rod to move telescopically along the third direction Z, and setting the pusher component 212 on its piston rod, the pusher component 212 can move along the third direction Z.

[0123] In some other embodiments, the number of cell storage slots 2211 on the gripping plate 221 may be less than the number of a row of storage positions 201 in the tray 2. During the gripping of the cell 3, the cell transfer mechanism 20 completes the gripping of a row of cells 3 by driving the cell gripping component 22 to grip at least twice.

[0124] In some other embodiments, the pusher 212 may also be a plurality of rod-shaped pusher structures or block-shaped pusher structures that are arranged corresponding to the cell storage slot 2211.

[0125] like Figure 4 and Figure 8 As shown, in some embodiments, the cell transfer mechanism 20 may further include a top-feeding component 25. The top-feeding component 25 is disposed on the tray conveying mechanism 10, positioned along the second direction X between the first conveying component 12 and the tray plate 111. When the cell gripping component 22 is in the gripping position, the top-feeding component 25 is correspondingly disposed to the cell gripping component 22, and is used to push out the cell 3 at the corresponding position in the tray 2 on the support member 133, so that the cell gripping component 22 can grip the cell 3 by magnetic attraction.

[0126] Specifically, the top-feeding assembly 25 may include a top-feeding drive 251 and a top-feeding component 252. The top-feeding drive 251 is electrically connected to the control mechanism, mounted on the tray conveying mechanism 10 via a bracket, and positioned below the plane of the tray plate 111. The top-feeding component 252 is mounted on the top-feeding drive 251 and can move up and down along the third direction Z under the drive of the top-feeding drive 251.

[0127] like Figure 4 As shown, when it is not necessary to push the battery cell 3, the top of the pusher 252 can be located below the plane of the tray plate 111 to avoid affecting the drive of the tray conveying mechanism 10 on the tray 2. When it is necessary to push the battery cell 3 in the tray 2, the pusher 252 can move upward under the drive of the pusher drive 251, and the top of the pusher 252 is higher than the plane of the tray plate 111. The battery cell 3 located in the tray 2 is pushed to the top of the tray 2 along the third direction Z so that the battery cell 3 can be received in the battery cell storage slot 2211.

[0128] It should be noted that the top material drive component 251 can be a structure such as a cylinder, and the top material component 252 can be mounted on its piston rod and move along with the extension and retraction of the piston rod.

[0129] It should be noted that, as Figure 9 As shown, each receiving position 201 of the tray 2 may have a through hole 203 penetrating through it. The top material member 252 can extend into the receiving position 201 through the through hole 203 to push out the battery cell 3 located in the receiving position 201.

[0130] See also Figure 8 In some embodiments, the top material member 252 includes a connecting seat 2521 and a plurality of top material columns 2522. The connecting seat 2521 is disposed on the top material drive member 251 and extends along a first direction Y. The plurality of top material columns 2522 are evenly spaced along the first direction Y on the connecting seat 2521.

[0131] The interval between two adjacent top material columns 2522 is equal to the interval between two adjacent cell storage slots 2211, and also equal to the interval between two adjacent receiving positions 201 along the first direction Y, so as to achieve a one-to-one correspondence between the top material columns 2522, the cell storage slots 2211, and the cells 3 in the receiving positions 201.

[0132] In some embodiments, the number of top posts 2522 may be equal to the number of cell storage slots 2211.

[0133] When the number of top-feeding columns 2522 equals the number of cell receiving slots 2211 and the number of a row of receiving positions 201, each top-feeding column 2522 can lift the cell 3 in the entire row of receiving positions 201, so that the cell gripping component 22 can grip the entire row of cell 3 at the same time, improving the cell feeding efficiency. For example, in Figure 7 and Figure 8 In the embodiment shown, there are 16 battery cell storage slots 2211 and 16 top material columns 2522.

[0134] In some other embodiments, the number of top material columns 2522 may be greater than or less than the number of cell storage slots 2211.

[0135] In some other embodiments, when the height of the tray 2 is set such that the portion of the battery cell 3 exposed in the tray 2 is sufficient for the magnetic attractor 222 of the battery cell storage slot 2211 to magnetically attract the battery cell 3, the battery cell transfer mechanism 20 may not be equipped with the top material assembly 25.

[0136] For example Figure 4 As shown, it should be noted that since the top material assembly 25 is disposed between the first conveying assembly 12 and the pallet plate 111 along the second direction X, and its top material component 252 is movably disposed along the third direction Z, the second guide rail 1311 in the third drive structure 131 of the second conveying assembly 13 is difficult to extend through the top material assembly 25 to below the clearance window 1111. Therefore, the moving seat 1312 and the vertical drive component 132 are also difficult to move to below the clearance window 1111.

[0137] In some embodiments, the length of each support rod 1332 of the support member 133 in the first direction Y is less than the interval between two adjacent top material columns 2522, and the setting position of each support rod 1332 in the first direction Y corresponds to a different interval space between two adjacent top material columns 2522. Thus, even if the support rod 1332 extends into the clearance window 1111 in the second direction X under the drive of the third drive structure 131, it can still pass through the top material member 252, and their movement paths will not affect each other.

[0138] By setting the support plate 1331, the vertical drive component 132 and the support rod 1332 can be connected. Even if the second guide rail 1311 is difficult to extend to the bottom of the clearance window 1111, the support rod 1332 can extend to the clearance window 1111 under the drive of the third drive structure 131, thereby realizing the transfer of the material tray 2 from the second conveying component 13 to the pallet plate 111.

[0139] In some other embodiments, when the cell transfer mechanism 20 is not equipped with the top material assembly 25, the second guide rail 1311 may also extend partially below the clearance window 1111, allowing the moving seat 1312 and the vertical drive member 132 to move below the clearance window 1111. This allows the cell 3 in the tray 2 on the support plate 1331 to be directly grasped by the cell transfer mechanism 20. In this embodiment, the support member 133 may consist only of the support plate 1331, or it may consist only of at least two support rods 1332.

[0140] like Figures 1 to 4 As shown, in some embodiments, the pipeline guiding mechanism 30 may be mounted on the support of at least some of the other mechanisms, and may be implemented using existing technologies such as existing tank chains, which will not be elaborated on here.

[0141] like Figure 1 and Figure 2 As shown, this application also constructs a battery cell feeding system, which may include the battery cell feeding device in any of the foregoing embodiments and a plurality of material trays 2. The material tray 2 may be placed on the material tray conveying mechanism 10 of the battery cell feeding device and transported along the second direction X.

[0142] See also Figure 9 The tray 2 has multiple receiving positions 201 arranged in a matrix to receive battery cells 3.

[0143] In some embodiments, each receiving position 201 has a through hole 203 on its bottom wall for making way for the top material assembly 25.

[0144] In some embodiments, at least a portion of the sidewall of the tray 2 may extend upwards with a limiting post 202 to cooperate with the limiting component 112 to achieve limiting in the third direction Z during transmission.

[0145] Understandably, the above-mentioned technical features can be used in any combination without restriction.

[0146] The above embodiments merely illustrate specific implementation methods of this application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this application's patent. It should be noted that those skilled in the art can freely combine the above technical features without departing from the concept of this application, and can also make several modifications and improvements, all of which fall within the protection scope of this application. Therefore, any equivalent transformations and modifications made within the scope of the claims of this application should be covered by the claims of this application.
