Description

Technical Field

[0001] The present invention belongs to the technical field of battery cell transportation, and in particular relates to a cylindrical battery cell sorting device for lithium battery PACK. Background Art

[0002] A lithium battery pack consists of several cells, a PCM board, and several auxiliary units. The cells in a lithium battery pack can be either new cells or secondary cells that have not yet reached the end of their service life and have been disassembled from other lithium battery packs. Before assembling the lithium battery pack, the cell voltage, internal resistance, expected life, and other performance tests must be conducted. The cell voltage within each battery pack must be consistent, and the testing of secondary cells is particularly important to avoid affecting the charge and discharge performance of the entire lithium battery pack due to inconsistent cell voltages. Currently, the performance testing of cells still relies mainly on manual testing. Although some equipment has been developed to achieve assembly line testing of cells, the consistent placement of cells still requires manual operation, and human factors still restrict the efficiency of cell testing.

[0003] To address the above-mentioned issues, Chinese patent publication number CN114275463B discloses a cylindrical cell sorting device for lithium battery packs, primarily relating to the field of cell conveying. The device comprises a conveying mechanism, a silo, a filling mechanism, a filling line, and a controller. The filling line is detachably provided with several silos. The conveying mechanism, the filling mechanism, and the filling line are all electrically connected to the controller. The silo is provided at the front end of the conveying mechanism. The filling mechanism comprises a filling frame, a clamping cylinder, an extension cylinder, and a drive cylinder. Clamping heads are provided on the cylinder rods at both ends of the clamping cylinder, each of which is provided with a contact sensor. A position sensor for detecting the position of the cell is provided below the filling mechanism. Two groups of filling lines are provided. The beneficial effect of the present invention is that it can arrange disordered cylindrical cells in a manner consistent in orientation, so that they meet the requirements of subsequent cell assembly line testing, thereby improving the efficiency and accuracy of cell testing.

[0004] This device can arrange the battery cells, but it does not take the positive and negative pole directions of the battery cells into consideration when arranging the battery cells, which makes it inconvenient for actually taking out the battery cells. Summary of the Invention

[0005] In order to solve the above problems, the present invention provides a cylindrical battery cell sorting device for lithium battery PACK, which can adjust the positive and negative electrodes of the sorted battery cells through the design of an adjustment mechanism.

[0006] To achieve the above-mentioned object, the technical solution of the present invention is as follows: A cylindrical cell sorting device for lithium battery packs, comprising a conveying mechanism, an adjustment mechanism, a guiding mechanism, and a collecting mechanism arranged transversely in sequence, wherein the conveying mechanism comprises a first support frame and a controller, the first support frame is provided with a first conveyor belt, and the first conveyor belt is provided with an electrode sensor;

[0007] The adjusting device is a chain which is fixedly mounted on the drive shaft and has a first end fixedly mounted on the drive shaft, the first end of which is engaged with the first gear and the second gear is engaged with the first gear and the second gear is engaged with the first gear and the second gear is engaged with the first gear and the second gear is engaged with the first gear and the second gear is engaged with the first gear and the second gear is engaged with the first gear and the second gear is engaged with the first gear and the second gear is

[0008] The guiding mechanism comprises a second supporting frame, a second conveyor belt is arranged on the second supporting frame, a portion of the second conveyor belt is located below the adjusting disk, and a laminating guiding mechanism is arranged on the second conveyor belt.

[0009] The principle of the basic solution is: during operation, the battery cells to be sorted are first placed on the first conveyor belt, and then the electrode sensor on the first conveyor belt will detect the battery cells. If it is sensed that a certain battery cell flowing on the first conveyor belt is opposite to the positive and negative directions set in the controller, the electrode sensor will send information to the controller. After receiving the electrode information, the controller will start the first electric component. Under the drive of the first electric component, the baffle will rise, and then the battery cell will fall onto the adjustment plate under the drive of the first conveyor belt and be blocked by the baffle. At the same time, under the control of the controller, the first driving component will be started, thereby the main gear will rotate. At the same time, because the main gear and the slave gear are engaged, the slave gear will also rotate, and because the slave gear is fixedly connected to the support shaft, the support shaft will rotate.

[0010] The adjustment disk will rotate as a result, so that the battery cell will rotate to the side close to the second conveyor belt, and when the battery cell rotates to the side of the second conveyor belt, the positive and negative poles of the battery cell will also be adjusted to the specified direction. At the same time, because the adjustment disk is inclined, the battery cell will not be easily thrown out of the adjustment disk when the adjustment disk rotates. Then, under the control of the controller, the first electric part is started again to raise the baffle to a certain height, and then the groove on the baffle will be exposed, and the spring will extend out of the groove due to the release of pressure. When the wedge extends out of the groove, it can contact the battery cell, and then the battery cell will fall onto the second conveyor belt under the pushing force of the wedge, and then the coating guide mechanism on the second conveyor belt will guide and coat the battery cell on the second conveyor belt, and then the battery cell will flow along the second conveyor belt to the collection mechanism and be collected.

[0011] The basic solution has the following beneficial effects: by detecting and sensing the positive and negative poles of the battery cells, and then arranging and adjusting the positive and negative poles of the battery cells, the positive and negative poles of all the battery cells can be aligned in the same position, thereby achieving the alignment of the positive and negative poles of the battery cells. After the alignment, the positive and negative poles of the arranged battery cells are in the same position, making it easier for subsequent staff to directly use the battery cells. In addition, when adjusting the positive and negative poles of the battery cells, the positive and negative poles of the battery cells can be reversed by simply rotating the adjustment disk, which is a simple and convenient operation.

[0012] Furthermore, the collecting mechanism includes a second driving member, a second supporting rod is provided on the second driving member, the second supporting rod is fixedly connected to the second supporting frame at one end away from the second driving member, the output end of the second driving member is fixedly connected to a rotating shaft, the rotating shaft is coaxially fixedly connected to a main bevel gear, the main bevel gear is meshed with a slave bevel gear, the slave bevel gear is coaxially fixedly connected to a transmission shaft, the transmission shaft is fixedly connected to a M-shaped bracket at one end away from the slave bevel gear, each end of the M-shaped bracket is fixedly connected to a collecting box, the collecting box is located below the second conveyor belt, and a pressure sensor is provided at the bottom of the collecting box.

[0013] The principle and beneficial effects of the basic scheme are: during operation, the adjusted battery cells will fall from the second conveyor belt into the collection box. As more battery cells fall into the collection box, the weight will become heavier. Then, when the pressure sensor detects that the weight reaches a pre-stored threshold, the pressure sensor will send information to the controller. After receiving the pressure information, the controller will start the second drive member. Driven by the second drive member, the main bevel gear will rotate. At the same time, because the main bevel gear is engaged with the slave bevel gear, the slave bevel gear will also rotate. As a result, the M-shaped bracket will rotate, so that the unfilled collection box will be rotated to the bottom of the second conveyor belt to load the remaining battery cells.

[0014] Furthermore, a plurality of guide plates are provided on the second support frame, and the guide plates are located on a side close to the collection box.

[0015] The principle and beneficial effect of the basic solution are: the design of the guide plate can make the battery cells on the second conveyor belt fall into the collection box more accurately, reducing the possibility of accidental falling of the battery cells.

[0016] Furthermore, the coating guide mechanism includes a hollow top plate, which is located above the second conveyor belt, and support vertical rods are fixedly connected on both sides of the top plate, and the support vertical rods are fixedly connected on both sides of the second support frame. A rotating shaft is provided in the top plate, and a diamond block is rotatably fitted on the rotating shaft, and connecting rods are hinged at both ends of the diamond block, and the connecting rod is fixedly connected to a guide rod at one end away from the diamond block. The guide rod passes through the bottom of the top plate and extends to the outside of the top plate, and a second electric part is fixedly connected to the guide rod, and a sleeve rod is fixedly connected to one end of the guide rod away from the diamond block. The sleeve rod is located above the second conveyor belt, and an installation groove larger than the diameter of the battery cell is provided on the sleeve rod near the end of the second conveyor belt, and a protective film with a sticky film is provided on the sleeve rod, and a sliding groove corresponding to the guide rod is provided at the bottom of the top plate.

[0017] The principle and beneficial effects of the basic scheme are as follows: when the battery cells flowing onto the second conveyor belt are coated, the second electric component is started first, and then, driven by the second electric component, the guide rod at one end of the diamond block will approach the diamond block. At the same time, because the connecting rod is hinged at both ends of the diamond block, when the guide rod at one end approaches the diamond block, the connecting rod at the other end of the diamond block will also pull the guide rod at the other end of the diamond block closer to the diamond block, and at the same time, the sleeve rod will approach the battery cell. At the same time, the battery cell will be moved into the installation groove under the squeezing force of the sleeve rod, and the protective films on the sleeve rod will adhere to each other. Therefore, when the second electric component drives the sleeve rod to move away from the battery cell, the protective film can be sleeved on the battery cell, and then the coating operation of the battery cell can be realized. At the same time, after the two stages of the battery cell are coated, the battery cell can be protected to a certain extent to avoid damage to the battery cell due to continuous movement and long-term placement, thereby affecting subsequent removal and use.

[0018] Furthermore, the laminating guide mechanism further includes a first push plate and a second push plate, and the first push plate and the second push plate are fixedly connected to the side of the sleeve rod away from the adjustment mechanism.

[0019] The principle and beneficial effect of the basic solution are: when the battery cell is being coated, as the sleeve rod approaches the battery cell, the first push plate and the second push plate will gradually approach the battery cell, and can guide and organize the battery cell to a certain extent to avoid the subsequent battery cell position being inaccurate and affecting the organization effect.

[0020] Furthermore, the first conveyor belt and the second conveyor belt are both provided with a plurality of anti-slip bumps.

[0021] The principle and beneficial effects of the basic solution are: the design of the anti-slip protrusions can increase the friction when the battery cells contact the first conveyor belt and the second conveyor belt, and to a certain extent reduce the possibility of the battery cells being misaligned between the first conveyor belt and the second conveyor belt.

[0022] Furthermore, limit plates are provided on both sides of the adjustment disk.

[0023] The principle and beneficial effect of the basic solution are: the design of the limit plate can reduce the possibility of the battery cell falling to the ground due to the rotational force when the adjustment disk rotates.

[0024] Furthermore, a sponge layer is provided on the limiting plate.

[0025] The principle and beneficial effect of the basic solution are: when the battery cell contacts the limit plate, the design of the sponge layer can reduce the impact force between the battery cell and the limit plate, thereby reducing damage to the battery cell.

The guide rod 29 is fixedly connected to a sleeve rod 33 at one end away from the diamond block 26. The sleeve rod 33 is located above the second conveyor belt 11. An installation groove 34 larger than the diameter of the battery cell is provided at one end of the sleeve rod 33 close to the second conveyor belt 11.

[0038] The collection mechanism includes a second drive member 13, on which a second support rod 12 is provided. The second support rod 12 is fixedly connected to the second support frame 10 at one end away from the second drive member 13. The output end of the second drive member 13 is fixedly connected to a rotating shaft, which is coaxially fixedly connected to a main bevel gear 23. The main bevel gear 23 is meshed with a slave bevel gear 24. The slave bevel gear 24 is coaxially fixedly connected to a transmission shaft 25. The transmission shaft 25 is fixedly connected to a cross-shaped bracket 15 at one end away from the slave bevel gear 24. Each end of the cross-shaped bracket 15 is fixedly connected to a collection box 14. The collection box 14 is located below the second conveyor belt 11. A pressure sensor is provided at the bottom of the collection box 14. A number of anti-slip bumps are provided on the first conveyor belt 1 and the second conveyor belt 11. Specifically, the first drive member and the second drive member are preferably motors, and the first electric member and the second electric member are preferably electric cylinders.

[0039] The specific implementation process is as follows: during operation, the battery cells to be sorted are first placed on the first conveyor belt 1, and then the electrode sensor on the first conveyor belt 1 will detect the battery cells. If it is sensed that a certain battery cell flowing on the first conveyor belt 1 is opposite to the positive and negative directions set in the controller, the electrode sensor will send information to the controller. After receiving the electrode information, the controller will start the first electric component 20. Under the drive of the first electric component 20, the baffle 17 will rise, and then the battery cells will fall onto the adjustment disk 8 driven by the first conveyor belt 1 and be blocked by the baffle 17. At the same time, under the control of the controller, the first driving component 4 will be started, thereby the main gear will rotate. At the same time, because the main gear and the slave gear 6 are engaged, the slave gear 6 will also rotate, and because the slave gear 6 is fixedly connected to the support shaft 19, the support shaft 19 will rotate.

[0040] As a result, the adjusting disk 8 will rotate, so that the battery cell rotates to the side close to the second conveyor belt 11, and when the battery cell rotates to the side of the second conveyor belt 11, the positive and negative poles of the battery cell will also be adjusted to the specified direction. At the same time, because the adjusting disk 8 is inclined, the battery cell is not easily thrown out of the adjusting disk 8 when the adjusting disk 8 rotates. Then, under the control of the controller, the first electric component 20 is started again to raise the baffle 17 to a certain height, and then the groove 18 on the baffle 17 will be exposed, thereby the spring 22 will extend out of the groove 18 due to the release of pressure. When the wedge block 21 extends out of the groove 18, it can contact the battery cell, and then the battery cell will fall onto the second conveyor belt 11 under the pushing force of the wedge block 21;

[0041] When the battery cells flowing onto the second conveyor belt 11 are coated, the second electric component 30 is first started. Then, under the drive of the second electric component 30, the guide rod 29 at one end of the diamond block 26 will approach the diamond block 26. At the same time, because the connecting rod 28 is hinged at both ends of the diamond block 26, when the guide rod 29 at one end approaches the diamond block 26, the connecting rod 28 at the other end of the diamond block 26 will also pull the guide rod 29 at the other end of the diamond block 26 to approach the diamond block 26. At the same time, the sleeve rod 33 will approach the battery cells. At the same time, the battery cell will be moved into the installation groove 34 under the squeezing force of the sleeve rod 33, and the protective films on the sleeve rod 33 will adhere to each other. Therefore, when the second electric component 30 drives the sleeve rod 33 to move away from the battery cell, the protective film can be sleeved on the battery cell, and then the coating operation of the battery cell can be realized. At the same time, after the two stages of the battery cell are coated, the battery cell can be protected to a certain extent to avoid the battery cell being damaged under constant movement and long-term storage, thereby affecting the subsequent removal and use;

[0042] Then the adjusted battery cells will fall from the second conveyor belt 11 into the collection box 14. As more battery cells fall into the collection box 14, the weight will become heavier. Then when the pressure sensor detects that the weight reaches a preset threshold, the pressure sensor will send information to the controller. After receiving the pressure information, the controller will start the second driving member 13. Driven by the second driving member 13, the main bevel gear 23 will rotate. At the same time, because the main bevel gear 23 is engaged with the slave bevel gear 24, the slave bevel gear 24 will also rotate. As a result, the M-shaped bracket 15 will rotate, so that the unfilled collection box 14 will rotate to the bottom of the second conveyor belt 11 to load the remaining battery cells.

[0043] Example 2

[0044] The difference from the above embodiment is that a plurality of guide plates are provided on the second support frame 10 , and the guide plates are located near the side of the collecting box 14 .

[0045] The specific implementation process is as follows: The design of the guide plate can make the battery cells on the second conveyor belt 11 fall into the collection box 14 more accurately, reducing the possibility of accidental falling of the battery cells.

[0046] Example 3

[0047] The difference from the above embodiment is that the laminating guide mechanism further includes a first push plate 7 and a second push plate, and the first push plate 7 and the second push plate are fixedly connected to the side of the sleeve rod 33 away from the adjustment mechanism.

[0048] The specific implementation process is as follows: when the battery cell is being coated, as the sleeve rod 33 approaches the battery cell, the first push plate 7 and the second push plate will also gradually approach the battery cell, and can guide and organize the battery cell to a certain extent to avoid the subsequent battery cell position being inaccurate and affecting the organization effect.
