[0062] A battery pack is a unit composed of multiple battery modules, used to store and provide electrical energy. During the battery pack assembly process, the battery cells are assembled into a battery holder according to the positive and negative polarity pattern, and then processed through other steps to form battery modules.

[0063] Conventional assembly equipment is often used for mass production and requires a large number of components, such as a robotic arm that automatically grabs battery cells. This results in a large and expensive assembly system, making it unsuitable for small-batch production.

[0064] Therefore, it is necessary to provide a battery pack assembly device with a smaller volume and lower cost.

[0065] In view of the above technical problems, the present disclosure provides a battery pack assembly device, such as Figure 1 shown.

[0066] The battery pack assembling device comprises an operation table 1, a cell slot assembly 2, a sliding table 3, a driving assembly 4, a first pushing assembly 5, a second pushing assembly 6 and a lifting mechanism 7. The operation table 1 has an operation hole 10 for the first cell support 100 to extend out, wherein the first cell support 100 is parallel to the first direction X and the third direction Z, and perpendicular to the second direction Y, and the first cell support 100 has multiple rows of through holes arranged along the third direction Z. The cell slot assembly 2 has multiple sub-cell slots 20 arranged along the first direction X, and the cell slot assembly 2 is slidably connected with the operation table 1 along the first direction X and the second direction Y. The sliding table 3 has a sliding channel 30 arranged obliquely along the first direction X, the sliding channel 30 is used to carry multiple cells, and the multiple cells are arranged along the length direction of the sliding channel 30, and the first pushing assembly 5 is used to push the cells at the lower end of the sliding channel 30 into the sub-cell slots 20 of the cell slot assembly 2. The driving assembly 4 is used to drive the cell slot assembly 2 to slide along the first direction X, so as to adjust the sub-cell slots 20 opposite to the lower end of the sliding channel 30, and drive the cell slot assembly 2 to be opposite to the first cell support 100. The second pushing assembly 6 is used to push the cell slot assembly 2 to slide along the second direction Y, so as to make the cells inserted into at least one row of through holes of the first cell support 100. The lifting mechanism 7 is used to carry the first cell support 100, and the lifting mechanism 7 is used to drive the first cell support 100 to move along the third direction Z.

[0067] The first cell support 100 has multiple through holes for placing the cells.

[0068] The technical solution provided by the embodiment of the present disclosure can reduce the volume and cost of the battery pack assembly device. When assembling the battery pack, a plurality of battery cells are placed on the slide 30 of the slide 3. The driving component 4 drives the battery cell slot assembly 2 to slide along the first direction X, so that the sub-battery cell slot 20 on the battery cell slot assembly 2 is opposite to the lower end of the slide 30. At this time, the battery cell located at the lower end of the slide 30 is pushed to the sub-battery cell slot 20 by the first pushing component 5, and then the other battery cells on the slide 30 roll down along the slide 30. The driving component 4 continues to drive the battery cell slot assembly 2 so that the other sub-battery cell slots 20 are opposite to the lower end of the slide 30, and then the first pushing component 5 repeats the above operation until the battery cell slot assembly 2 is full of battery cells. After the battery cell slot assembly 2 is full of battery cells, the driving component 4 drives the battery cell slot assembly 2 to move in the opposite direction until the battery cell slot assembly 2 is aligned with the first battery cell bracket 100. The second pushing component 6 then pushes the battery cell slot assembly 2 filled with battery cells toward the first battery cell holder 100, and inserts the battery cells on the battery cell slot assembly 2 into the first battery cell holder 100. Finally, the second pushing component 6 pulls the battery cell slot assembly 2 back. After the first battery cell holder 100 is filled with a row of battery cells, the lifting mechanism 7 drives the first battery cell holder 100 to move downward, so that the upper row of through holes of the first battery cell holder 100 is aligned with the battery cell slot assembly 2, and repeats the above operation until the first battery cell holder 100 is filled with battery cells. Since the slide 3 is provided, after placing multiple battery cells on the slide 3, each battery cell can slide to the bottom of the slide 3, and there is no need to set up other mechanisms to grab the battery cells. Therefore, there are fewer components in the battery pack assembly device, which makes the battery pack assembly device smaller in size and lower in cost.

[0069] In some examples, such as Figure 1 and Figure 2 As shown, the cell tank assembly 2 includes a first cell tank 21 and a second cell tank 22. The first cell tank 21 is located above the second cell tank 22. The first cell tank 21 is used to accommodate positive electrode cells, and the second cell tank 22 is used to accommodate negative electrode cells. The first cell tank 21 and the second cell tank 22 both have sub-cell tanks 20, and the number of sub-cell tanks 20 in the first cell tank 21 and the second cell tank 22 is the same.

[0070] The slide 3 includes a first slide 31 and a second slide 32. The first pushing assembly 5 includes a first push rod 51 and a second push rod 52. The first push rod 51 is used to push the positive battery cell located at the lower end of the first slide 31 to the first battery cell slot 21, and the second push rod 52 is used to push the negative battery cell located at the lower end of the second slide 32 to the second battery cell slot 22. The first slide 31 and the second slide 32 both have a slide 30. To prevent the battery cell from deviating from the slide 30, both sides of the slide 30 have a side plate 301. The side plates 301 have notches at the bottom end of the first slide 31 and the bottom end of the second slide 32, so that the first push rod 51 and the second push rod 52 can withdraw the battery cell from the bottom end of the first slide 31 and the bottom end of the second slide 32.

[0071] like Figure 1 As shown, the driving assembly 4 includes a first driving mechanism 41 and a second driving mechanism 42. The first driving mechanism 41 is used to drive the first battery cell slot 21 to slide along the first direction X, and the second driving mechanism 42 is used to drive the second battery cell slot 22 to slide along the first direction X.

[0072] When assembling the battery pack assembly device, multiple positive cells are placed on the first slide 31 and multiple negative cells are placed on the second slide 32. Then, the first drive mechanism 41 drives the first cell slot 21 to slide to a position opposite the notch at the bottom of the first slide 31. The second drive mechanism 42 drives the second cell slot 22 to slide to a position opposite the notch at the bottom of the second slide 32. The first push rod 51 then pushes the positive cells into the first cell slot 21, and the second push rod 52 pushes the negative cells into the second cell slot 22.

[0073] After the first and second cell slots 21 and 22 are filled with cells, the first and second drive mechanisms 41 and 42 respectively move the first and second cell slots 21 and 22 to their initial positions. Finally, the second pushing assembly 6 pushes the first and second cell slots 21 and 22 toward the first cell support 100.

[0074] In this way, the assembly efficiency of the battery pack can be accelerated, so that the first battery cell holder 100 can be loaded with two rows of battery cells at the same time.

[0075] For example, Figure 2 As shown, the first push rod 51 and the second push rod 52 each include a fixed platform 501, a telescopic rod 502 and a second push plate 503. The fixed platform 501 is fixed to the operating table 1, one end of the telescopic rod 502 is connected to the fixed platform 501, and the other end is connected to the second push plate 503, which is used to push the battery cell.

[0076] In other examples, the cell slot assembly 2 may further include a third cell slot and a fourth cell slot, thereby further improving assembly efficiency. The embodiment of the present disclosure does not specifically limit the number of cell slots in the cell slot assembly 2.

[0077] In some examples, if the first battery cell slot 21 and the second battery cell slot 22 slide in the same direction at the same time, the first battery cell slot 21 and the second battery cell slot 22 may also share the same driving mechanism.

[0078] In some examples, such as Figure 2 and Figure 3As shown, the first slide 31 and the second slide 32 are located on either side of the operating hole 10. The height of the first slide 31 gradually increases as it moves away from the operating hole 10. The height of the second slide 32 gradually increases as it moves away from the operating hole 10. This facilitates the placement of battery cells on the first and second slides 31, 32. If the first and second slides 31, 32 are located on the same side of the operating hole 10, the first slide 31 will be located above the second slide 32. As a result, when placing a negative battery cell on the second slide 32, it will be obstructed by the first slide 31.

[0079] When assembling the battery pack, the first drive mechanism 41 and the second drive mechanism 42 respectively drive the first cell slot 21 and the second cell slot 22 to move away from each other. After the first cell slot 21 and the second cell slot 22 are fully loaded with battery cells, the first drive mechanism 41 and the second drive mechanism 42 respectively drive the first cell slot 21 and the second cell slot 22 to move toward each other.

[0080] The following is an exemplary description of the implementation of the first driving mechanism 41 and the second driving mechanism 42 .

[0081] In some examples, such as Figure 2 and Figure 3 As shown, the first drive mechanism 41 includes a first motor 411, a first gear 412 and a first support plate 413. The first motor 411 is connected to the first gear 412 through a coupling. The first rack 211 is engaged with the first gear 412, and the first battery cell 21 is connected to the first support plate 413 in a sliding manner along the first direction X. When it is necessary to drive the first battery cell 21 to slide, the first motor 411 drives the first gear 412 to rotate. Since the first rack 211 is engaged with the first gear 412, the first battery cell 21 will move linearly under the drive of the first rack 211. Since the length of the first battery cell 21 is long, the provision of the first support plate 413 can provide good support for the first battery cell 21 and prevent the first support plate 413 from tilting during movement. Moreover, when the first battery cell 21 needs to move along the second direction Y, the first rack 211 can be disengaged from the first gear 412, so that the first drive mechanism 41 will not affect the movement of the second pushing assembly 6.

[0082] The second drive mechanism 42 includes a second motor 421, a second gear 422, and a second support plate 423. The second motor 421 and the second gear 422 are connected by a coupling. The second rack 221 of the second battery cell 22 meshes with the second gear 422, and the second battery cell 22 and the second support plate 423 are slidably connected along the first direction X. The operating principle of the second drive mechanism 42 is the same as that of the first drive mechanism 41 and will not be further described here.

[0083] In some examples, such as Figure 1 and Figure 3 As shown, the drive assembly 4 also includes a first backplate 43, a second backplate 44 and a connecting rod 45. The first backplate 43 is fixed to the operating table 1 and is opposite to the first slide 31. The first slide 31 is located between the first push rod 51 and the first backplate 43. The first support plate 413 is fixed to the first backplate 43. The second backplate 44 is fixed to the operating table 1 and is opposite to the second slide 32. The second slide 32 is located between the second push rod 52 and the second backplate 44. One end of the connecting rod 45 is fixed to the second backplate 44, and the other end of the connecting rod 45 is connected to the first motor 411. The first backplate 43 can support the first battery cell slot 21 in the second direction Y. Similarly, the second backplate 44 can support the second battery cell slot 22 in the second direction Y.

[0084] In some examples, such as Figure 4 and Figure 5 As shown, the operating platform 1 also has two baffles 11, which are located on both sides of the operating hole 10. The inner sides of the two baffles 11 have first sliding grooves 110, and the battery cell trough assembly 2 has bosses 23 on both sides, which are slidably connected to the first sliding grooves 110. This can enhance the stability of the battery cell trough assembly 2 during sliding.

[0085] In some examples, such as Figure 3 As shown, the second pushing assembly 6 includes a fixed block 61, a cylinder body 62, a rod body 63 and a first push plate 64. The fixed block 61 is fixed to the operating table 1, the cylinder body 62 is looped around the rod body 63, and is slidably connected to the rod body 63 along the second direction Y, the cylinder body 62 is connected to the fixed block 61, and the rod body 63 is connected to the first push plate 64. The first push plate 64 is used to push the battery cell slot assembly 2 to slide along the second direction Y. The side walls of the first battery cell slot 21 and the second battery cell slot 22 are provided with a sliding groove 201, and the sliding groove 201 extends along the first direction X. The first push plate 64 has a sliding protrusion, which is located in the sliding groove 201, so that the first battery cell slot 21 and the second battery cell slot 22 can be slidably connected to the first push plate 64.

[0086] In some examples, such as Figure 6 As shown, the lifting mechanism 7 includes a lifting motor 71, a limiting rod assembly 72, and a first support plate 73. The limiting rod assembly 72 extends parallel to the third direction Z. The lifting motor 71 is used to drive the first support plate 73 to slide along the limiting rod assembly 72. The first support plate 73 is used to support the first battery cell holder 100. The longitudinal cross-section of the first support plate 73 is U-shaped, that is, the first support plate 73 forms a U-shaped groove. This prevents the first battery cell holder 100 from deflecting when the push plate assembly 8 pushes it.

[0087] The limiting rod assembly 72 includes a screw and a slide rod. The lifting motor 71 is in driving connection with the screw. When the lifting motor 71 drives the screw to rotate, the first support plate 73 can move up and down along the screw. The slide rod is used to assist in positioning the first support plate 73 and prevent it from shifting during movement.

[0088] In some examples, such as Figure 1 As shown, the battery pack assembly apparatus further includes a base plate 9, a second support plate 1a, and a support plate drive mechanism 1b. The base plate 9 is located below the operating table 1. The second support plate 1a is used to support the second battery cell holder. The support plate drive mechanism 1b is used to drive the second support plate 1a to slide along the base plate 9 in the second direction Y to engage the second battery cell holder with the first battery cell holder 100.

[0089] When the height of the first cell holder 100 is the same as that of the second cell holder, the second cell holder on the second support plate 1a is joined to the first cell holder 100. The interface of the second support plate 1a is U-shaped, thereby preventing the second cell holder from falling off the second support plate 1a.

[0090] The bottom plate 9 has a second sliding groove 91 extending along the second direction Y. The bottom of the second supporting plate 1 a has a protrusion located in the second sliding groove 91 , so that the second supporting plate 1 a can slide along the bottom plate 9 .

[0091] When the first cell holder 100 is filled with cells, the support plate driving mechanism 1b drives the second support plate 1a toward the first support plate 73, thereby combining the second cell holder with the first cell holder 100. Then, the push plate assembly 8 pushes the second cell holder and the first cell holder 100, causing the second cell holder to leave the second support plate 1a and the first cell holder 100 to leave the first support plate 73.

[0092] Exemplarily, the support plate driving mechanism 1b may be a telescopic cylinder.

[0093] In some examples, such as Figure 6 As shown, the battery pack assembly device further includes a push plate assembly 8. The push plate assembly 8 is located below the operating table 1. When the first battery cell holder 100 faces the push plate assembly 8, the push plate assembly 8 is used to push the first battery cell holder 100 to slide along the first direction X.

[0094] When assembling the battery pack, the lifting mechanism 7 is located at the bottom. After the first cell holder 100 is placed on the lifting mechanism 7, the lifting mechanism 7 drives the first cell holder 100 upward, positioning it above the access hole 10. After the first cell holder 100 is fully loaded with cells, the lifting mechanism 7 drives it downward. Then, the push plate assembly 8 pushes the first cell holder 100 off the lifting mechanism 7.

[0095] The working process of the battery pack assembly device is exemplarily described below.

[0096] In the first step, the lifting motor 71 drives the screw in the limiting rod assembly 72 to rotate, so that the first battery cell holder 100 moves upward to above the operating hole 10 .

[0097] In the second step, a plurality of battery cells are placed on the first slide 31 and the second slide 32. The first driving mechanism 41 and the second driving mechanism 42 respectively drive the first battery cell tank 21 and the second battery cell tank 22 to slide away from each other.

[0098] In the third step, the first push rod 51 pushes the positive battery cell at the lower end of the first slide 31 to the first battery cell slot 21, and the second push rod 52 pushes the negative battery cell at the lower end of the second slide 32 to the second battery cell slot 22. This continues until the first battery cell slot 21 and the second battery cell slot 22 are filled with battery cells.

[0099] In the fourth step, the first driving mechanism 41 and the second driving mechanism 42 respectively drive the first battery cell slot 21 and the second battery cell slot 22 to slide in a direction approaching each other until the first battery cell slot 21 and the second battery cell slot 22 are opposite to the first battery cell bracket 100 .

[0100] In the fifth step, the second pushing assembly 6 pushes the first cell slot 21 and the second cell slot 22 to the first cell holder 100. After the cell is inserted into the through hole of the first cell holder 100, the second pushing assembly 6 drives the first cell slot 21 and the second cell slot 22 away from the first cell holder 100.

[0101] In the sixth step, the lifting mechanism 7 moves the first cell holder 100 downward so that the through holes in the upper row are opposite to the first cell slots 21 and the second cell slots 22. The above operation is then repeated until the first cell holder 100 is filled with cells.

[0102] In the seventh step, the lifting mechanism 7 drives the first battery cell holder 100 filled with battery cells to descend to the bottom plate 9 .

[0103] In the eighth step, the support plate driving mechanism 1 b drives the second support plate 1 a to approach the first support plate 73 , thereby combining the second battery cell holder with the first battery cell holder 100 .

[0104] In the ninth step, the push plate assembly 8 pushes the second cell holder and the first cell holder 100 , so that the second cell holder leaves the second support plate 1 a and the first cell holder 100 leaves the first support plate 73 .

[0105] The above descriptions are merely optional embodiments of the present disclosure and are not intended to limit the present disclosure. Any modifications, equivalent replacements, improvements, etc. made within the principles of the present disclosure shall be included in the scope of protection of the present disclosure.
