Description

Technical Field

[0001] The utility model relates to the technical field of battery pack assembly, in particular to a device for loading a battery cell module into a box and a battery pack. Background Art

[0002] The battery pack mainly includes a box body and a battery cell module. The battery cell module is usually placed in the box body in a way of being loaded into the box with the positive side up. That is, the opening of the box body faces upward, and a heat-conducting structural adhesive is coated on the bottom plate of the box body. Before the heat-conducting structural adhesive solidifies, the battery cell module is hoisted from top to bottom into the box body by manual or mechanical means and bonded with the heat-conducting structural adhesive. Although this way of loading into the box with the positive side up is simple and convenient, since the battery cell module is formed by bonding a plurality of small battery cells in an array, that is, the battery cell module cannot form a rigid integral structure. When there are a large number of battery cells in the battery cell module, making the whole battery cell module relatively large, when using hoisting to load it into the box with the positive side up, it may cause the whole battery cell module to sink downward and bend or scatter.

[0003] To solve the above problems, usually suction cups are added to the tops of the respective battery cells in the battery cell module. However, when hoisting the whole battery cell module by the suction cups, there is a risk of suction cup failure, and the suction cups are vulnerable parts that need to be maintained and replaced irregularly, resulting in a relatively high assembly cost of the whole battery pack.

[0058] In order to make the technical problems solved by the present invention, the technical solutions adopted and the technical effects achieved more clearly, the technical solutions of the present invention are further explained below with reference to the accompanying drawings and through specific implementation methods.

[0059] like Figures 1 to 12 As shown, in this embodiment, a battery cell module boxing device and a battery pack are proposed, the battery pack includes a box body and a battery cell module 1, the box body includes a bottom plate 21 and an end plate 22, the battery cell module 1 is provided with end plates 22 at opposite ends along the X-axis, and the battery cell module 1 includes a plurality of battery cells 11 connected in an array, that is, each battery cell 11 is interconnected by a buffer insulation pad with double-sided adhesive; the battery cell module 1 is loaded upside down into the box body based on the battery cell module boxing device, so as to avoid the entire battery cell module 1 from sinking and bending or scattering when loaded into the box body, thereby ensuring the smooth loading of larger battery cell modules 1; and, it can avoid the risk of suction cup failure caused by lifting the entire battery cell module 1 by suction cup, and can reduce the assembly cost of the entire battery pack. Here, there is no limitation on the specific type of battery pack.

[0060] Specifically, Figures 1 to 12 As shown, the battery module boxing device includes a frame 10, a support frame 3, a clamping assembly 4, a pressing assembly 5 and a receiving transfer member 7; wherein the frame 10 is a U-shaped structure, the support frame 3 is connected to the frame 10 by rotation around the X axis, the end plate 22 and the battery module 1 can be placed on the support frame 3, and the pole of the battery 11 is arranged downward along the Z axis; the clamping assembly 4 is arranged on one side of the support frame 3, and the clamping assembly 4 can push one of the end plates 22 along the X axis, so that the battery module 1 is pushed to a preset length along the X axis, so as to be sleeved on the two end plates 22 The limiting belt 12 is provided, and the bottom plate 21 is placed upside down on the battery module 1; the pressing component 5 is connected to the supporting frame 3, and the pressing component 5 can press the bottom plate 21 downward to the battery module 1 along the Z-axis to avoid the bottom plate 21 and the battery module 1 from being separated from each other during the subsequent flipping process; the receiving transfer member 7 can be moved to the supporting frame 3 along the Y-axis, and the receiving transfer member 7 can receive the bottom plate 21 and the battery module 1 after the supporting frame 3 is flipped 180° around the X-axis, and can connect the end plate 22 to the bottom plate 21 to form a box, thereby placing the battery module 1 in the box.

[0061] The support frame 3 is connected to the frame 10 by rotating it around the X-axis, placing the end plate 22 and the battery cell module 1 on the support frame 3, and setting the pole of the battery cell 11 downward along the Z-axis, that is, the battery cell module 1 is inverted into the support frame 3; at the same time, the clamping assembly 4 is pushed against one of the end plates 22 and the battery cell module 1 along the X-axis, so that the size of the battery cell module 1 on the X-axis is a preset length, so that the limiting belts 12 are sleeved on the two end plates 22 at both ends of the battery cell module 1 to limit each battery cell 11 in the battery cell module 1; then the bottom plate 21 is inverted on the battery cell module 1, and the pressing The component 5 presses the bottom plate 21 downward along the Z axis to the battery cell module 1; then the support frame 3 with the battery cell module 1, the bottom plate 21 and the end plate 22 are turned 180° around the X axis, and the pressing effect of the pressing component 5 on the bottom plate 21 is released, so that the bottom plate 21 and the battery cell module 1 thereon are dropped onto the receiving and transferring member 7 as a whole. At this time, the bottom plate 21 is placed horizontally on the receiving and transferring member 7, and the receiving and transferring member 7 transfers the battery cell module 1 and the bottom plate 21 as a whole to the outside of the frame 10 along the Y axis, so as to realize the inverted installation of the battery cell module 1 into the box formed by the bottom plate 21 and the end plate 22. In this embodiment, the receiving and transferring member 7 includes a moving trolley, so that the battery cell module 1 and the bottom plate 21 can be transferred as a whole to the outside of the frame 10 by reciprocating movement of the moving trolley on the Y axis. The moving trolley adopts a moving trolley structure commonly used in the prior art, and the structure and working process of the moving trolley are not described in detail here.

[0062] Compared with the prior art, the battery cell module loading device in this embodiment changes the loading method of the battery cell module 1 into the box body; when the battery cell module 1 includes a large number of battery cells 11, which makes the entire battery cell module 1 larger, the above-mentioned inverted loading method is adopted, which, compared with the prior art of using hoisting to load the battery cell module 1 upright, can prevent the entire battery cell module 1 from sinking and bending or scattering, thereby ensuring the smooth loading of the larger battery cell module 1; and, it is no longer necessary to add suction cups on the top of each battery cell 11 in the battery cell module 1, which can avoid the risk of suction cup failure caused by hoisting the entire battery cell module 1 by the suction cup, and can reduce the assembly cost of the entire battery pack.

[0063] Specifically, the box body in the battery pack also includes the above-mentioned limiting belt 12, which extends along the X-axis. The limiting belt 12 is used to limit and fix the two end plates 22 and each battery cell 11 in the battery cell module 1 to form a complete battery cell module 1, avoid the problem of separation between the battery cell 11 and the end plate 22 in the battery cell module 1, and ensure the overall structure of the battery cell module 1.

[0064] The battery module 1 is formed by fixing with a limiting band 12 in the battery pack. On the one hand, it can make the structure of the battery pack simple and the cost low. On the other hand, since there are many choices for the size of the limiting band 12 and it has a certain elasticity, a battery module 1 with a larger size can be formed by fixing with the limiting band 12, and the rigidity strength of the battery module 1 can be improved by the limiting and fixing effect of the limiting band 12.

[0065] Furthermore, the battery pack includes multiple groups of battery modules 1, and each group of battery modules 1 is arranged in sequence along the Y-axis. That is, in each group of battery modules 1, end plates 22 are respectively provided at opposite ends of the battery module 1 along the X-axis, and a limiting band 12 is sleeved on the two end plates 22 to form each group of independent battery modules 1, and each group of battery modules 1 is located on a bottom plate 21 to form a battery pack with a larger size, so that the battery pack can meet the usage scenarios with large power requirements.

[0066] Specifically, the battery pack in this embodiment specifically includes a bottom plate 21 and two groups of battery modules 1 arranged side by side on the bottom plate 21, and end plates 22 are respectively provided at both ends of each group of battery modules 1, and two limiting bands 12 are sleeved. The structure and assembly of the battery pack are relatively simple and convenient, the cost is low, and the limiting and fixing effect is good, and it can be applied to the usage scenarios with large power requirements.

[0067] Furthermore, as Figures 8 to 12 shown, the end faces of the pole columns of each battery cell 11 placed in the support frame 3 are flush. That is, the battery module 1 is placed in the support frame 3 with the end faces of the pole columns of each battery cell 11 as the reference, and a thermal conductive structural adhesive is respectively provided on one end face of each battery cell 11 close to the bottom plate 21, so that the end faces of each battery cell 11 after being coated with the thermal conductive structural adhesive are flush, so that the bottom plate 21 is horizontally bonded to the thermal conductive structural adhesive.

[0068] By placing the battery module 1 upside down in the support frame 3. On the one hand, it can make the end faces of the pole columns of each battery cell 11 flush, ensure good flatness of the pole columns, be conducive to subsequent welding of the integrated busbar on each pole column, and further ensure the welding quality between the pole column and the integrated busbar. On the other hand, it can make the end faces of each battery cell 11 after being coated with the thermal conductive structural adhesive flush, so that the bottom plate 21 can be horizontally bonded to the thermal conductive structural adhesive, thus ensuring good bonding effect between the bottom plate 21 and the battery module 1 and avoiding the separation between the bottom plate 21 and the battery module 1.

[0069] It should be noted that as Figure 1 、 Figures 10 to 12As shown in the figure, two ribs 211 are oppositely arranged on the bottom plate 21 along the X-axis. The ribs 211 extend along the Y-axis. The battery cell module 1 is limited between the two ribs 211. On the same side, the ribs 211 are aligned with the end plate 22, so as to facilitate connecting the end plate 22 and the ribs 211 with bolts after subsequent flipping.

[0070] Furthermore, as Figures 2 to 5 shown, the support frame 3 includes an outer frame 31 and an inner frame 32; wherein, the outer frame 31 is rotatably connected to the inside of the frame 10 around the X-axis; the inner frame 32 includes a support plate 321 and two first side plates 322 oppositely arranged on the support plate 321. The support plate 321 is slidably connected to the outer frame 31 along the Y-axis. The support plate 321 can support the battery cell module 1 and limit the battery cell module 1 between the two first side plates 322. That is, the battery cell module 1 is placed on the support plate 321 and limited between the two first side plates 322 to place the battery cell module 1 inside the inner frame 32.

[0071] Specifically, as Figures 5 to 7 shown, the clamping assembly 4 includes a first driving member 41 and two second side plates 42; wherein, the fixed end of the first driving member 41 is arranged on the support plate 321; the two second side plates 42 are respectively connected to the support plate 321. The two second side plates 42 are respectively located at the opposite ends of the battery cell module 1 along the X-axis and are arranged outside the end plate 22, so that a square structure is formed by enclosing the two first side plates 322 and the two second side plates 42. The battery cell module 1 and the two end plates 22 are respectively limited and placed inside the square structure; and the driving end of the first driving member 41 is connected to one of the second side plates 42 and drives the second side plate 42 to move along the X-axis, so that the two second side plates 42 approach each other, so that the second side plate 42 pushes the end plate 22 and the battery cell module 1 along the X-axis to push each battery cell 11 in the battery cell module 1, so that the entire battery cell module 1 is pushed to a preset length along the X-axis. In this embodiment, the first driving member 41 can specifically be a handwheel. In other embodiments, the first driving member 41 can specifically be a motor.

[0072] By arranging the first driving member 41 and the second side plates 42 that cooperate with each other, the entire battery cell module 1 can be extruded to a preset length along the X-axis, so that the size of the battery cell module 1 along the X-axis meets the requirement of sleeving the limiting belt 12, so as to directly sleeve the limiting belt 12 on the end plates 22 at both ends of the battery cell module 1. In this embodiment, the limiting belt 12 can specifically be a steel belt with relatively high structural strength.

[0073] Furthermore, as Figures 2 to 5As shown, the pressing assembly 5 includes a connecting plate 51 and a pressing plate 52; wherein the connecting plate 51 extends along the Y-axis, and is slidably connected to the outer frame 31 along the Z-axis; the pressing plate 52 extends along the X-axis, and the connecting plates 51 are respectively connected to the opposite ends of the pressing plate 52 on the X-axis, and the battery module 1 is located between the two connecting plates 51, and the pressing plate 52 is slidably connected to the connecting plate 51 along the Y-axis, and the pressing plate 52 can press the bottom plate 21 downward along the Z-axis to the battery module 1.

[0074] By providing a connecting plate 51 and a pressing plate 52 that cooperate with each other, on the one hand, the connecting plate 51 and the pressing plate 52 will not interfere with the battery module 1, so that the battery module 1 can smoothly fall onto the receiving transfer member 7 after being flipped 180°; on the other hand, the pressing plate 52 can slide onto the battery module 1 along the Y-axis, so that the pressing plate 52 presses the bottom plate 21 downward along the Z-axis onto the battery module 1, thereby ensuring the connection stability between the bottom plate 21 and the battery module 1, and preventing the bottom plate 21 and the battery module 1 from detaching from each other during the flipping process.

[0075] It is worth noting that if Figures 2 to 5 As shown, in order to ensure that the pressing effect of the pressing plate 52 on the bottom plate 21 is better, multiple pressing plates 52 are connected between the two connecting plates 51, so that the multiple pressing plates 52 can be pressed against the bottom plate 21 at the same time, thereby ensuring that the pressing effect of the multiple pressing plates 52 on the bottom plate 21 is better. In this embodiment, two pressing plates 52 are connected between the two connecting plates 51, and the specific number of the pressing plates 52 is not limited here.

[0076] Furthermore, if Figures 2 to 5 As shown, the pressing assembly 5 also includes a pressing driving member 53, a second screw rod 54 and a nut of the second screw rod 54; wherein, the fixed end of the pressing driving member 53 is arranged on the outer frame 31, the second screw rod 54 extends along the Z axis, the second screw rod 54 is rotatably arranged on the outer frame 31, the nut of the second screw rod 54 is threadedly sleeved on the second screw rod 54, and the nut of the second screw rod 54 is fixedly connected to the connecting plate 51; the pressing driving member 53 can drive the second screw rod 54 to rotate, so that the nut of the second screw rod 54 moves on the second screw rod 54 along the Z axis, so as to drive the connecting plate 51 to move along the Z axis. In this embodiment, the pressing driving member 53 can specifically be a hand wheel. In other embodiments, the pressing driving member 53 can be a motor.

[0077] It is worth noting that if Figures 2 to 5As shown in the figure, since there are two connecting plates 51, correspondingly, there are two second lead screws 54, that is, one second lead screw 54 is arranged at each connecting plate 51; therefore, a synchronous belt 55 and synchronous pulleys 56 are connected between the two second lead screws 54, so as to enable the synchronous rotation of the two second lead screws 54 through the synchronous belt 55 and the synchronous pulleys 56, thereby enabling the synchronous movement of the two connecting plates 51 in the Z-axis direction, so that both ends of the pressing plate 52 can be synchronously pressed against the bottom plate 21, resulting in better synchronous pressing performance and pressing effect on the bottom plate 21; at the same time, a pressing driving member 53 is respectively connected to both ends of each second lead screw 54, so as to enable any one of the four pressing driving members 53 to drive the second lead screw 54 to rotate, providing operational flexibility and convenience for the sliding of the connecting plate 51 in the Z-axis direction.

[0078] Furthermore, as Figures 1 to 12 shown, at least one set of battery cell modules 1 is placed in the inner frame body 32. At opposite ends of each set of battery cell modules 1 in the X-axis direction, a limiting belt 12 and two end plates 22 are respectively arranged. Multiple sets of battery cell modules 1 are arranged side by side along the Y-axis; the battery cell module loading device further includes an adjustment assembly 6. The adjustment assembly 6 is arranged between the outer frame body 31 and the inner frame body 32. The adjustment assembly 6 can adjust the distance between adjacent two sets of battery cell modules 1 along the Y-axis, so as to adjust the distance between adjacent two sets of battery cell modules 1 to an appropriate distance, thereby enabling each set of battery cell modules 1 to be limited within a square structure formed in the inner frame body 32 at an appropriate distance, which is beneficial for directly bonding the bottom plate 21 to each battery cell module 1 subsequently. In this embodiment, two sets of battery cell modules 1 are placed in the inner frame body 32.

[0079] Specifically, the support plate 321 includes at least one sub-plate. One set of battery cell modules 1 is placed on one sub-plate, and the respective sub-plates are arranged along the Y-axis; as Figures 4 to 6 shown, the adjustment assembly 6 includes a second driving member 61, a first lead screw 62, and a first lead screw nut 63; wherein, the fixed end of the second driving member 61 is arranged on the outer frame body 31, the first lead screw 62 extends along the Y-axis, the first lead screw 62 is rotatably connected to the outer frame body 31, and the driving end of the second driving member 61 is connected to the first lead screw 62 to drive the first lead screw 62 to rotate around the Y-axis; the first lead screw nut 63 is threadedly sleeved on the first lead screw 62, and the bottom end of one sub-plate is fixedly connected to a first lead screw nut 63. The rotation of the first lead screw 62 can respectively drive each first lead screw nut 63 to move along the Y-axis, so as to drive the respective sub-plates to approach or move away from each other along the Y-axis, thereby adjusting the distance between adjacent two sub-plates, and further adjusting the distance between adjacent two sets of battery cell modules 1 to an appropriate distance.

[0080] It should be noted that second driving members 61 are respectively connected to opposite ends of the first lead screw 62, so that the first lead screw 62 can be driven to rotate by any one of the second driving members 61, providing operational flexibility and convenience for the rotation of the first lead screw 62. In this embodiment, the second driving member 61 may specifically be a handwheel. In other embodiments, the second driving member 61 may be a motor.

[0081] It should be noted that since two sets of battery cell modules 1 are arranged in the inner frame body 32, correspondingly, the support plate 321 includes two sub-boards, and a first side plate 322 is connected to one sub-board, so that the sub-board and the first side plate 322 can move synchronously along the Y-axis, thereby driving the battery cell modules 1 on each sub-board to approach or move away from each other along the Y-axis. Specifically, clamping assemblies 4 are arranged on each sub-board, that is, two second side plates 42 and a first driving member 41 are respectively arranged on each sub-board, so as to be able to independently push and clamp the end plates 22 and the battery cell modules 1 on each sub-board through the respective clamping assemblies 4, thereby ensuring that the lengths of the battery cell modules 1 in the inner frame body 32 are all preset lengths on the X-axis.

[0082] Furthermore, as Figure 2 and Figure 3 shown, the battery cell module loading device into the box further includes a third driving member 81 and a rotating shaft 82; wherein, the fixed end of the third driving member 81 is arranged on the frame 10; the rotating shaft 82 extends along the X-axis, the driving end of the third driving member 81 is connected to the rotating shaft 82 and drives the rotating shaft 82 to rotate around the X-axis, and the outer frame body 31 is fixedly sleeved on the rotating shaft 82, so as to be able to drive the outer frame body 31 to rotate synchronously around the X-axis through the rotating shaft 82, thereby being able to drive the inner frame body 32 and the battery cell modules 1 and the bottom plate 21 therein to flip 180° along the X-axis. Wherein, rotating shafts 82 are respectively and fixedly connected to opposite ends of the outer frame body 31 on the X-axis, and one rotating shaft 82 is drivingly connected to the third driving member 81, and the other rotating shaft 82 is rotatably arranged in the frame 10. In this embodiment, the third driving member 81 may specifically be a handwheel. In other embodiments, the third driving member 81 may be a motor.

[0083] The specific working process of the battery cell module loading device into the box in this embodiment is as follows:

[0084] First, buffer heat insulation pads with double-sided adhesive are pasted on each battery cell 11, so that the battery cells 11 are bonded to each other in an array to form the battery cell module 1.

[0085] Then, first place an end plate 22 of the first group of battery cell modules 1 inside the inner frame body 32, and then place a group of battery cell modules 1 inside the support frame body 3 with the end faces of the pole columns of each battery cell 11 flush. That is, make each battery cell 11 face downward and place them in two rows of twenty-six battery cells 11 adjacent to each other with positive and negative poles in sequence as a group of battery cell modules 1, and then place another end plate 22 inside the inner frame; and repeat the above steps to place another group of battery cell modules 1 inside the inner frame body 32; that is, there are two groups of battery cell modules 1 placed inside the inner frame body 32.

[0086] After that, make the first driving member 41 drive the second side plate 42 to move along the X-axis, so that the two second side plates 42 approach each other, causing the second side plate 42 to push against the end plate 22 and the battery cell module 1 along the X-axis, so as to push each battery cell 11 in the battery cell module 1, making the entire battery cell module 1 have a preset length along the X-axis, and sleeving a limiting belt 12 on the two end plates 22 at both ends of the battery cell module 1; and repeat the above process to squeeze the other group of battery cell modules 1 to the preset length and put a limiting belt 12 on this battery cell module 1.

[0087] Then, make the second driving member 61 drive the first lead screw 62 to rotate, so as to drive each first lead screw nut 63 on the first lead screw 62 to move along the Y-axis respectively, so as to drive the two splitter plates to approach each other along the Y-axis, thereby adjusting the distance between the two splitter plates, and further adjusting the distance between the two groups of battery cell modules 1 to an appropriate distance, so as to be able to inject an adhesive between the two groups of battery cell modules 1, making the two groups of battery cell modules 1 adhesively connected to each other.

[0088] After that, respectively coat a heat-conducting structural adhesive on one end face of each battery cell 11 close to the bottom plate 21, so that the end faces of each battery cell 11 after coating the heat-conducting structural adhesive are flush, and reversely and horizontally bond the bottom plate 21 to the heat-conducting structural adhesive. At this time, the two groups of battery cell modules 1 are located between the two convex strips 211, and one convex strip 211 is aligned with the two end plates 22 on the same side.

[0089] Then, make the two pressing plates 52 slide along the Y-axis to the directly above the battery cell module 1, and make the connecting plate 51 drive the pressing plate 52 to move downward along the Z-axis, so that the pressing plate 52 presses tightly against the bottom plate 21, thereby making the pressing plate 52 press tightly against the bottom plate 21 downward along the Z-axis onto the battery cell module 1.

[0090] After that, make the third driving member 81 drive the rotating shaft 82 to rotate around the X-axis, so as to drive the outer frame body 31 to rotate around the X-axis synchronously through the rotating shaft 82, thereby being able to drive the inner frame body 32 and the battery cell module 1 and the bottom plate 21 inside it to flip 180° along the X-axis; at this time, the bottom plate 21 and the battery cell module 1 are supported by the two pressing plates 52; and connect the end plates 22 on both sides to the bottom plate 21 respectively through bolts.

[0091] Finally, the two pressure plates 52 are slid along the Y-axis to separate from the bottom plate 21 and the battery cell module 1, so that the bottom plate 21 and the battery cell module 1 fall onto the receiving transfer member 7 as a whole, so that the bottom plate 21, the end plate 22, the limiting belt 12 and the battery cell module 1 are moved out of the frame 10 as a whole through the receiving transfer member 7; thereby completing the entire process of inverted installation of the battery cell module 1 into the box.

[0092] The battery cell module loading device in the present embodiment adopts a method of loading the battery cell module 1 upside down. When the battery cell module 1 includes a large number of battery cells 11, which makes the entire battery cell module 1 larger, compared with the prior art of loading the battery cell module 1 upright by hoisting, the inverted loading method can prevent the entire battery cell module 1 from sinking and bending or scattering, thereby ensuring the smooth loading of the larger battery cell module 1. In addition, the entire loading process is simple and convenient, and the loading of the battery cell module 1 can be completed by only one flipping, so that the assembly efficiency of the battery cell 11 package is higher.

[0093] Furthermore, the battery cell module box-entering device in the present embodiment places the battery cell module 1 in the support frame 3 based on the flush end faces of the poles of each battery cell 11, so as to ensure good flatness of the poles; and can make the end faces of each battery cell 11 flush after being coated with the thermally conductive structural adhesive, thereby ensuring that the bottom plate 21 is horizontally bonded to the thermally conductive structural adhesive.

For ordinary technicians in this field, according to the concept of the present invention, there will be changes in the specific implementation methods and application scopes. The contents of this specification should not be understood as limiting the present invention.
