Description

Technical Field

[0001] The present application relates to the field of lithium battery production equipment manufacturing, and specifically to a battery cell feeding device. Background Art

[0002] Battery cells generally need to be processed (such as gluing, attaching spacers, etc.) and tested during the transportation process. Battery cells with qualified test results will continue to be transported to the downstream process, while battery cells with unqualified test results will need to be removed from the conveying mechanism. After the unqualified battery cells are removed, vacancies will be created at the corresponding positions of the conveying mechanism. In order to ensure that the battery cells are continuously transported to the downstream processing station at a predetermined rhythm, a qualified battery cell needs to be added to the vacant position after each unqualified battery cell is removed.

[0003] The existing feeding device can only directly supply the next qualified battery cell to the post-processing station after the unqualified battery cell is removed. However, due to the process requirements of the post-processing station (such as the battery cell stacking station), the polarity of the battery cells transported by the conveying mechanism may not be the same. If the polarity of two adjacent battery cells is opposite, the pole direction of the rejected unqualified battery cell will be different from that of the next qualified battery cell.

[0004] Therefore, the next qualified battery cell cannot be used to replace the rejected unqualified battery cell. In this case, the only way is to manually adjust the polarity of a qualified battery cell to be consistent with the polarity of the rejected unqualified battery cell, and then add the adjusted qualified battery cell to the vacant position. This will affect the automation rhythm of the production equipment and reduce the production efficiency of the equipment. Utility Model Content

[0057] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0058] like Figures 1 to 3 As shown, the battery cell feeding device in the embodiment of the present application includes a conveying mechanism 1, a first conveying mechanism 2, a second conveying mechanism, a third conveying mechanism 3, a processing mechanism and a detection mechanism, wherein:

[0059] The conveying mechanism 1 is used to convey the battery cells. A processing station B, a detection station C and a rejection station D are sequentially arranged in the conveying direction of the conveying mechanism 1 .

[0060] The processing mechanism is arranged at the side of the processing station B, and is used to perform corresponding processing on the battery cells located at the processing station B. The detection mechanism is arranged at the side of the detection station C, and is used to perform detection on the battery cells located at the detection station C to determine whether the processed battery cells are qualified.

[0061] The first transport mechanism 2 is disposed at the side of the rejecting station D, and is used to remove the battery cells at the rejecting station D that are determined to be unqualified by the detection mechanism from the rejecting station D. Optionally, an NG battery cell output mechanism 5 is disposed at the side of the rejecting station D, and the first transport mechanism 2 places the unqualified battery cells rejected from the rejecting station D onto the NG battery cell output mechanism 5 .

[0062] A replenishing station A is also provided in the conveying direction of the conveying mechanism 1. The replenishing station A is located in front of the processing station B. The second transport mechanism is located on the side of the replenishing station A. It is used to pick up a replenishing cell and adjust the polarity of the replenishing cell to the same polarity as the rejected unqualified cell when the unqualified cell is rejected from the rejection station D, and then transport the replenishing cell to the replenishing station A.

[0063] The third transport mechanism 3 is arranged between the feeding station A and the rejecting station D, and is used to obtain the feeding cells from the feeding station A, and transport and place the feeding cells at the rejecting station D. In particular, the transport path of the third transport mechanism 3 is located above the transport path of the transport mechanism 1, and when the feeding cells pass through the processing station B, the processing mechanism is also used to process the feeding cells. When the feeding cells pass through the inspection station C, the inspection mechanism is also used to inspect the feeding cells.

[0064] The battery cell replenishing device in the embodiment of the present application adjusts the polarity of the replenished battery cells before replenishing, performs corresponding processing and detection on the replenished battery cells, and finally replenishes the replenished battery cells to the rejection station, thereby ensuring that the replenished battery cells replenished to the rejection station are processed qualified battery cells and have the same polarity as the rejected unqualified battery cells.

[0065] The battery cell feeding device of the present application does not disrupt the order of the battery cells being processed, and can ensure the accuracy of the polarity of the fed battery cells, thereby ensuring the automation rhythm of the production equipment and improving the feeding efficiency.

[0066] The battery cell involved in the embodiment of the present application is a square shell battery cell, and the positive and negative poles of the battery cell are both located on one end face of the battery cell. Polarity adjustment is to adjust the angle of the battery cell so that the orientation of the positive and negative poles of the battery cell meets the requirements. For example, the positive pole of the replenishing battery cell picked up by the second transport mechanism is located on the left side of the negative pole, while the positive pole of the rejected unqualified battery cell is located on the right side of the negative pole. Therefore, the replenishing battery cell needs to be rotated 180 degrees to adjust its polarity to be consistent with the polarity of the rejected unqualified battery cell.

[0067] Optionally, the processing mechanism in the embodiment of the present application includes a gluing section and a patch section, and correspondingly, the processing station includes a gluing station and a patch station, that is, the processing of the battery cell in the embodiment of the present application is to apply the spacer to the battery cell. Specifically, the patch station is located after the gluing station. The gluing section is arranged on the side of the gluing station, and is used to attach the adhesive strip to the battery cell located at the gluing station. The patch mechanism is arranged on the side of the patch station, and is used to bond the spacer to the battery cell located at the patch station via the adhesive strip.

[0068] When the replenished battery cell passes through the gluing station under the transport of the third transport mechanism 3, the gluing unit is also used to attach the glue strip to the replenished battery cell. When the replenished battery cell passes through the patch station, the patch unit is also used to bond the spacer to the replenished battery cell via the glue strip.

[0069] Of course, in other embodiments, the processing of the battery cells may also be other processing procedures, and correspondingly, a corresponding processing mechanism is provided on the side of the processing station.

[0070] like Figures 1 to 5As shown, optionally, the third transport mechanism 3 includes a first translation drive module 31, a first lifting drive module 32 and a first clamping assembly 33, wherein: the first lifting drive module 32 is connected to the movable part of the first translation drive module 31, and the first clamping assembly 33 is connected to the movable part of the first lifting drive module 32. The first translation drive module 31 is used to drive the first clamping assembly 33 to translate back and forth between the feeding station A and the rejection station D, and the first lifting drive module 32 is used to drive the first clamping assembly 33 to move up and down, so that the first clamping assembly 33 clamps the feeding cell located at the feeding station A, and places the clamped feeding cell processed by the processing station at the rejection station D.

[0071] The process of the third transport mechanism 3 transporting the battery cells is as follows:

[0072] First, the first translation driving module 31 drives the first clamping assembly 33 to the feeding station A. The first clamping assembly 33 clamps the feeding cell from the feeding station A.

[0073] Next, the first translation drive module 31 drives the first clamping assembly 33 to move to the rejection station D. During this process, the battery cell clamped on the first clamping assembly 33 passes through the processing station B and the detection station C in sequence. When the battery cell passes through the processing station B, the processing mechanism processes the replenished battery cell, and when the battery cell passes through the detection station C, the detection mechanism detects the processed replenished battery cell.

[0074] When the refilled cells that have completed the inspection arrive at the rejection station D, for the qualified refilled cells confirmed after the inspection, the first lifting drive module 32 drives the first clamping assembly 33 to descend, and the first clamping assembly 33 places the refilled cells to the rejection station D, thereby completing the refilling. For the unqualified cells confirmed after the inspection, the first transport mechanism 2 can transport them to the NG cell output mechanism 5. If the refilling fails, the third transport mechanism 3 needs to repeat the above process and implement refilling.

[0075] The first translation drive module 31 can adopt various existing translation drive modules that can drive the first clamping assembly 33 to translate back and forth between the feeding station A and the rejection station D. For example, the first translation drive module 31 is a synchronous belt driven by a drive motor and a pulley, and the synchronous belt extends from the feeding station A to the rejection station D. The first lifting drive module 32 is fixedly connected to one side of the synchronous belt (such as the lower belt body). When the synchronous belt runs in a first direction (such as clockwise), the first clamping assembly 33 is driven from the feeding station A to the rejection station D. When the synchronous belt runs in a second direction (such as counterclockwise), the second clamping assembly 33 is driven from the rejection station D to the feeding station A.

[0076] like Figure 4 and Figure 5As shown, optionally, the first lifting drive module includes a connecting plate 321, a lifting plate 322 and a lifting drive member 323. Among them, the connecting plate 321 is connected to the movable part of the first translation driving module 31 (such as a side belt body of the synchronous belt), the lifting plate 322 is slidably connected to the connecting plate 321 and can slide up and down relative to the connecting plate 321, and the first clamping assembly 33 is installed on the lifting plate 322. The lifting drive member 323 is arranged on the connecting plate 321 and is transmission-connected to the lifting plate 322. The lifting drive member 323 is used to drive the lifting plate 322 to slide up and down relative to the connecting plate 321, so as to drive the second clamping assembly 33 to rise and fall.

[0077] Optionally, the first clamping assembly 33 includes a first clamping driving module 331, a first clamping plate 332, and a second clamping plate 333, wherein: the first clamping driving module 331 is disposed on a movable component of the first lifting driving module 32 (such as the lifting plate 322 in the above embodiment), and the first clamping plate 332 and the second clamping plate 333 are connected in pairs to the driving end of the first clamping driving module 331. The first clamping driving module 331 is used to drive the first clamping plate 332 and the second clamping plate 333 to clamp or release the feeding battery cell.

[0078] The first clamping driving module 331 can adopt various existing clamping driving modules that can drive the first clamping plate 332 and the second clamping plate 333 to move toward the middle and separate toward both sides.

[0079] As known to those skilled in the art, the battery cells are generally stored in a vertical state on a tray or a rack, while the conveying mechanism 1 may need to convey the battery cells to the processing station in a horizontal state. Therefore, after picking up the replenishing battery cells, the second transport mechanism 4 not only needs to adjust the polarity of the replenishing battery cells, but also needs to flip the replenishing battery cells to a horizontal state and place them at the replenishing station A.

[0080] like Figure 6 to Figure 7 As shown, optionally, the second transport mechanism 4 includes a polarity adjustment part 41 and a flipping part 42, wherein: the polarity adjustment part 41 is used to pick up the replenishing battery cell placed in an upright state, and drive the replenishing battery cell to rotate, so as to adjust the polarity of the replenishing battery cell to the same polarity as the rejected unqualified battery cell. The replenishing station A is arranged at the head end of the conveying mechanism 1, and the flipping part 42 is located in front of the replenishing station. The flipping part 42 is used to receive the replenishing battery cell that has completed the polarity adjustment 41, and flip the replenishing battery cell toward the replenishing station A, so that the replenishing battery cell falls to the conveying mechanism 1 at the replenishing station A in a horizontal state. The third transport mechanism 3 obtains the replenishing battery cell from the conveying mechanism 1.

[0081] It can be seen that, through the cooperation of the polarity adjustment part 41 and the flipping part 42, the second transport mechanism 4 realizes the polarity adjustment and flipping of the replenished battery cells, so that the replenished battery cells have the same polarity as the rejected unqualified battery cells and fall onto the conveying mechanism 1 in a horizontal state.

[0082] Optionally, the second transport mechanism 4 further includes a transfer platform, and after the polarity adjustment of the battery cell is completed, the polarity adjustment unit 41 transports the supplementary battery cell with completed polarity adjustment to the transfer platform, and the flipping unit 42 obtains the supplementary battery cell with completed polarity adjustment from the transfer platform. Of course, the polarity adjustment unit 41 can also transport the supplementary battery cell with completed polarity adjustment to the flipping unit 42 by itself.

[0083] like Figure 6 As shown, optionally, the polarity adjustment unit 41 includes a second translation drive module 411, a second lifting drive module 412, a first rotation module 413 and a second clamping assembly 414, wherein: the second lifting drive module 412 is connected to the movable part of the second translation drive module 411, the first rotation module 413 is connected to the movable part of the second lifting drive module 412, and the second clamping assembly 414 is connected to the movable part of the first rotation module 413. The second translation drive module 411 and the second lifting drive module 412 are used to cooperate in driving the second clamping assembly 414 to translate and lift, so as to drive the second clamping assembly 414 to pick up the replenishing battery cell placed in an upright state, and the first rotation module 413 is used to drive the second clamping assembly 414 to rotate, so as to adjust the polarity of the replenishing battery cell to be the same as the polarity of the rejected unqualified battery cell.

[0084] The second translation drive module 411 and the second lifting drive module 412 can both adopt various existing translation drive modules. For example, the synchronous belt driven by the drive motor and the pulley in the above embodiment can be adopted, and the screw drive module composed of the screw motor, the screw and the screw nut can be adopted. The first rotation module 413 can adopt various existing rotation modules that can drive the second clamping assembly 414 to rotate in the horizontal plane, such as a rotation module composed of a motor, a driving gear and a driven gear.

[0085] The second clamping assembly 414 may adopt a structure similar to the first clamping assembly 33 in the previous embodiment, ie, two pairs of clamping plates driven by a clamping drive.

[0086] like Figure 7As shown, optionally, the flip part 42 includes a mounting bracket 421, a flip plate 422, a flip driving member 423 and a third clamping assembly 424, wherein: the flip driving member 423 is arranged on the mounting bracket 421, the flip plate 422 is rotatably connected to the mounting bracket 421 and connected to the driving end of the flip driving member 423, and the third clamping assembly 424 is arranged on the flip plate 422. The third clamping assembly 424 is used to clamp the charging cell, and the flip driving member 423 is used to drive the flip plate 422 to flip downward, so that the third clamping assembly 424 flips the charging cell to a horizontal state.

[0087] The third clamping assembly 424 may adopt a structure similar to the first clamping assembly 33 in the previous embodiment, ie, two pairs of clamping plates driven by a clamping drive.

[0088] like Figures 8 to 9 As shown, in other embodiments, the second transport mechanism 4 includes a third translation drive module 43, a third lifting drive module 44, a second rotation module 45, a fourth clamping assembly 46 and a flipping drive module 47, wherein: the third lifting drive module 44 is connected to the movable part of the third translation drive module 43, the second rotation module 45 is connected to the third lifting drive module 44, the fourth clamping assembly 46 is connected to the movable part of the second rotation module 45, and the flipping drive module 47 is arranged on the fourth clamping assembly 46. The third translation drive module 43 and the third lifting drive module 44 are used to cooperate in driving the fourth clamping assembly 46 to translate and lift, so as to drive the fourth clamping assembly 46 to pick up the replenishing battery cell placed in an upright state, and to transport the replenishing battery cell to the replenishing station A. The second rotation module 45 is used to drive the fourth clamping assembly 46 to rotate during the transport process, so as to adjust the polarity of the replenishing battery cell to be the same as the polarity of the rejected unqualified battery cell. The flipping drive module 47 is used to flip the charging cell from an upright state to a horizontal state during transportation.

[0089] It can be seen that through the coordinated driving of the third translation drive module 43, the third lifting drive module 44, the second rotation module 45 and the flipping drive module 47, the fourth clamping assembly 46 can directly transport the picked up replenishment battery cells to the replenishment station A, and complete the polarity adjustment and flipping of the replenishment battery cells during the transportation process, thereby improving the battery cell replenishment efficiency.

[0090] Optionally, the feeding station A is located above the conveying mechanism 1. After the flip driving module 47 flips the feeding cell to a horizontal state, the feeding cell remains on the fourth clamping assembly 46 and does not fall on the conveying mechanism 1. The third handling mechanism 3 directly obtains the feeding cell from the fourth clamping assembly 46. Of course, the feeding station A can also be set on the conveying mechanism 1. The flip driving module 47 flips the feeding cell to a horizontal state and then releases the feeding cell, so that the feeding cell falls on the conveying mechanism 1 at the feeding station A. The third handling mechanism 3 obtains the feeding cell from the conveying mechanism 1.

The flipping drive module 47 is arranged on the fourth clamping plate 463, and the flipping drive module 47 is transmission-connected to the second rotating clamping block 465. The second clamping drive module 461 is used to drive the third clamping plate 462 and the fourth clamping plate 463 to move toward the middle, so as to drive the first rotating clamping block 464 and the second rotating clamping block 465 to clamp the feeding battery cell from both sides. The flipping drive module 47 is used to drive the second rotating clamping block 465 to rotate, so as to flip the feeding battery cell from a vertical state to a horizontal state.

[0093] Of course, the flip drive module 47 can also be set on the third clamping plate 462, and the flip drive module 47 is connected to the first rotating clamp block 464 by transmission. The flip drive module 47 drives the first rotating clamp block 464 to rotate, so as to flip the replenishing battery cell from the vertical state to the horizontal state. Alternatively, the flip drive module 47 is set on the third clamping plate 462 and the fourth clamping plate 463, and the flip drive module 47 is connected to the first rotating clamp block 464 and the second rotating clamp block 465 by transmission, and the flip drive module 47 simultaneously drives the first rotating clamp block 464 and the second rotating clamp block 465 to rotate, so as to flip the replenishing battery cell from the vertical state to the horizontal state.

[0094] The flip driving module 47 can adopt various existing flip driving modules that can drive at least one of the first rotating clamp 464 and the second rotating clamp 465 to rotate. Fig. 9 In the illustrated embodiment, the flip driving module 47 includes a motor, a driving wheel, a driven wheel and a synchronous belt, wherein the driving wheel is connected to the driving shaft of the motor, the driven wheel is fixedly connected and coaxially arranged with the second rotating clamp 465, and the synchronous belt is sleeved on the driving wheel and the driven wheel. When the motor drives the synchronous belt to operate via the driving wheel, the driven wheel and the second rotating clamp 465 are driven to rotate synchronously.
