[0050] 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.

[0051] In the existing cell pre-processing method, thickness detection, cleaning and flipping processes are completed in different processing equipment, which not only increases the equipment cost but also affects the processing efficiency.

[0052] In view of this, the present application provides a battery cell pretreatment device, which can sequentially perform thickness measurement, cleaning and flipping operations on the battery cells, thereby improving the pretreatment efficiency of the battery cells and reducing equipment costs.

[0053] like Figure 1 to Figure 2 As shown, the cell pretreatment device in the embodiment of the present application includes a conveying mechanism 1, a thickness measuring mechanism 2, a cleaning mechanism 3, a handling mechanism 4, a turning mechanism 5, a feeding mechanism 6 and an NG buffer mechanism 7, wherein:

[0054] The conveying mechanism 1 is configured to convey the battery cell 100 placed in an upright state on the conveying mechanism along a first horizontal direction (such as the X-axis direction in the figure), and a thickness measuring station, a cleaning station and a handling station are sequentially arranged on the conveying path of the conveying mechanism 1.

[0055] The thickness measuring mechanism 2 is disposed at the thickness measuring station, and is configured to perform thickness detection, OCV or code scanning on the battery cell 100 located at the thickness measuring station to determine whether the thickness of the battery cell 100 is qualified.

[0056] The cleaning mechanism 3 is disposed at the cleaning station, and is configured to clean the battery cells 100 located at the thickness measuring station and having passed the thickness test. That is, when the battery cells 100 after the thickness test are transported to the thickness measuring station, the cleaning mechanism 3 only cleans the battery cells 100 having passed the thickness test, and the battery cells 100 having failed the thickness test directly pass through the thickness measuring station without being cleaned.

[0057] The transport mechanism 4 is disposed at the transport station, and is configured to transport the cleaned battery cells at the transport station to the flip mechanism 5 , and to transport the battery cells at the transport station that fail the thickness test to the NG buffer mechanism 7 .

[0058] The flipping mechanism 5 is arranged on the side of the unloading mechanism 6, and is configured to flip the cleaned battery cell 100 in an upright state toward the unloading mechanism 6, so that the battery cell 100 falls onto the unloading mechanism 6 in a horizontal state. The unloading mechanism 6 is used to transport the battery cell 100 to the next workstation.

[0059] It can be seen that, through the cooperation of the conveying mechanism 1, the thickness measuring mechanism 2, the cleaning mechanism 3, the transporting mechanism 4, the flipping mechanism 5 and the unloading mechanism 6, the battery cell pretreatment equipment provided in the embodiment of the present application can successively and sequentially perform thickness measurement, cleaning and flipping operations on the battery cell 100, and convey the pretreated battery cell 100 to the next workstation. Compared with the existing pretreatment method, the battery cell pretreatment equipment provided in the embodiment of the present application improves the pretreatment efficiency of the battery cell and reduces the equipment cost.

[0060] like Figure 2 Optionally, the conveying mechanism 1 includes a first conveyor belt, a first driving member, and a plurality of first position-limiting components 11, wherein the first driving member is configured to drive the first conveyor belt to move cyclically along a first horizontal direction, the first conveyor belt is configured to carry the battery cells 100 and transport the battery cells in an upright state along a first horizontal direction, and the plurality of first position-limiting components 11 are installed on the first conveyor belt in parallel along the first direction, and each first position-limiting component 11 includes two first position-limiting blocks installed in parallel on the first conveyor belt, and there is a gap between the two first position-limiting blocks for the battery cells 100 in an upright state to fit and insert. In this way, it can be ensured that the battery cells 100 are kept on the first conveyor belt in an upright state, and a predetermined size of interval is maintained between adjacent battery cells 100.

[0061] Similarly, if Figure 6 As shown, optionally, the unloading mechanism 6 includes a second conveyor belt, a second driving member and multiple groups of second limiting components 61, the second driving member is configured to drive the second conveyor belt to move cyclically along the first horizontal direction, the second conveyor belt is configured to carry the battery cells and transport the battery cells 100 in a horizontal state along the first horizontal direction, multiple groups of second limiting components 61 are installed in parallel on the second conveyor belt along the first direction, each group of second limiting components 61 includes two second limiting blocks installed in parallel on the second conveyor belt, and there is a gap between the two second limiting blocks for the battery cells in the horizontal state to fit and insert. In this way, it can be ensured that the battery cells 100 are kept on the second conveyor belt in a horizontal state, and the interval of a predetermined size is maintained between adjacent battery cells 100.

[0062] like Figure 3 to Figure 4As shown, optionally, the thickness measuring mechanism 2 includes a first mounting bracket 21, a first pressure block 22, a second pressure block 23, a thickness measuring sensor 24 and a sensing sheet 25, wherein: the first pressure block 22 and the second pressure block 23 are relatively arranged on the first mounting bracket 21, and a thickness measuring channel for the power core 100 to pass through is formed between the first pressure block 22 and the second pressure block 23. The thickness measuring sensor 24 is arranged on one of the first pressure block 22 and the second pressure block 23, and the sensing sheet 25 is arranged on the other of the first pressure block 22 and the second pressure block 23. The first pressure block 22 and the second pressure block 23 are configured to be able to move closer to the middle and separate to both sides. When the first pressure block 22 and the second pressure block 23 move closer to the middle, the battery cell 100 located in the thickness measuring channel is pressed from both sides, and the sensing sheet 25 cooperates with the thickness measuring sensor 24 to measure the thickness of the battery cell 100.

[0063] The thickness measuring mechanism 2 measures the thickness of the battery cell 100 as follows:

[0064] In the initial state, the first pressing block 22 and the second pressing block 23 are separated to both sides, and the conveying mechanism 1 conveys the battery cell 100 placed in an upright state toward the thickness measuring mechanism 2 .

[0065] When the battery cell 100 enters the thickness measuring channel between the first pressing block 22 and the second pressing block 23, the conveying mechanism 1 temporarily conveys the battery cell 100. The first pressing block 22 and the second pressing block 23 move toward the middle until the battery cell 100 in the thickness measuring channel is pressed from both sides.

[0066] Next, the induction sheet 25 cooperates with the thickness measuring sensor 24 to measure the thickness of the battery cell 100. After the thickness measuring operation of the battery cell 100 is completed, the first pressing block 22 and the second pressing block 23 are opened to both sides to release the battery cell 100, and the conveying mechanism 1 continues to convey.

[0067] Optionally, the thickness sensor 24 is a photoelectric sensor. When the first pressing block 22 and the second pressing block 23 press the battery cell 100 in the thickness measuring channel from both sides, the photoelectric sensor obtains the distance between it and the sensing sheet through laser ranging, and the distance is the thickness value of the battery cell 100. Of course, the thickness sensor 24 can also use other existing types of sensors.

[0068] Optionally, the thickness measuring mechanism 2 further includes an OCV detector or a barcode scanner located outside the thickness measuring channel to perform OCV or barcode scanning on the battery cell.

[0069] Optionally, the thickness measuring mechanism 2 further includes a first pressure block driving member 26 and a second pressure block driving member 27 which are relatively arranged on the first mounting bracket 21, wherein: the first pressure block 22 is connected to the driving end of the first pressure block driving member 26, and the first pressure block driving member 26 is used to drive the first pressure block 22 to move toward or away from the second pressure block 22. The second pressure block 23 is connected to the driving end of the second pressure block driving member 27, and the second pressure block driving member 27 is used to drive the second pressure block 23 to move toward or away from the first pressure block 22.

[0070] By providing the first pressing block driving member 26 and the second pressing block driving member 27, the first pressing block 22 and the second pressing block 23 are driven, so that the first pressing block 22 and the second pressing block 23 can press and release the battery cell 100 located in the thickness measuring channel from both sides. The first pressing block driving member 26 and the second pressing block driving member 27 can be, for example, a cylinder, and the first pressing block 22 and the second pressing block 23 are connected to the ends of the telescopic rod of the cylinder.

[0071] like Figure 4 As shown, optionally, the thickness measuring mechanism 2 further includes an in-position sensing sensor 28 disposed on the first mounting bracket 21. When the battery cell enters the thickness measuring channel, the in-position sensing sensor 28 is triggered to generate an in-position signal, and sends the in-position signal to the first pressing block driving member 26, the second pressing block driving member 27 and the thickness measuring sensor 24. After receiving the in-position signal, the first pressing block driving member 26 and the second pressing block driving member 27 immediately control the first pressing block 22 and the second pressing block 22 to press the battery cell 100 located in the thickness measuring channel from both sides, and the thickness measuring sensor 24 performs the thickness measuring operation.

[0072] like Figure 5 As shown, optionally, the cleaning mechanism 3 includes a first cleaning part 31 and a second cleaning part 32, wherein: the first cleaning part 31 is located at a first side of the cleaning station, and is used to clean one side surface of the battery cell located at the cleaning station. The second cleaning part 32 is located at a second side of the cleaning station, and is used to clean the other side surface of the battery cell located at the cleaning station.

[0073] Optionally, the first cleaning section 31 and the second cleaning section 32 have the same structure, and the first cleaning section 31 includes a first horizontal driving module 311, a first lifting driving module 312, a dust suction pipe 313 and a plasma cleaner 314, wherein: the first lifting driving module 312 is connected to the movable part of the first horizontal driving module 311, the dust suction pipe 313 is connected to the movable part of the first lifting driving module 312, the air inlet of the dust suction pipe 313 faces the cleaning station, and the plasma cleaner 314 is arranged at the air inlet of the dust suction pipe 313.

[0074] When the vertical battery cell enters the cleaning station between the first cleaning section 31 and the second cleaning section 32 driven by the conveying mechanism 1, the plasma cleaner 314 of the first cleaning section 31 is close to the first side surface of the battery cell, and the plasma cleaner 314 of the second cleaning section 32 is close to the second side surface of the battery cell.

[0075] Next, the first horizontal driving module 311 and the first lifting driving module 312 cooperate to drive the plasma cleaner 314 to translate along the first horizontal direction and lift along the vertical direction, so that the corresponding plasma cleaner 314 moves closely to the first side surface or the second side surface of the battery cell to clean the debris on the first side surface or the second side surface of the battery cell. The dust suction pipe 313 removes the debris generated by the plasma cleaner 314 in the process of cleaning the battery cell.

[0076] Of course, the first cleaning part 31 and the second cleaning part 32 may also adopt cleaning mechanisms of other structures capable of cleaning the first side surface or the second side surface of the battery cell.

[0077] Continue to refer Figure 5 As shown, optionally, the first cleaning part 31 and the second cleaning part 32 both include a regular block 315 disposed above the plasma cleaner 314. When the first horizontal driving module 311 and the first lifting driving module 312 cooperate to drive the plasma cleaner 314 to perform plasma cleaning on the battery cell, the regular block 315 synchronously moves close to the corresponding side surface of the battery cell, thereby regularizing the battery cell and also scraping off the hard-to-clean dirt on the corresponding side surface of the battery cell.

[0078] like Figure 6 As shown, optionally, the transport mechanism 4 includes a second translation drive module 41 and at least one picking portion 42, wherein: the picking portion 42 is connected to the movable part of the second translation drive module 41, and the second translation drive module 41 is used to drive the picking portion 42 to translate, so as to drive the picking portion 42 to pick up the cleaned battery cells at the transport station and transport them to the flipping mechanism 5, and to pick up the battery cells that fail the thickness test at the transport station and transport them to the NG buffer mechanism 7.

[0079] In this way, qualified battery cells and unqualified battery cells after thickness detection can be classified and unloaded.

[0080] The second translation drive module 41 can adopt various existing linear drive modules that can drive the pickup part 42 to translate. For example, the second translation drive module 4 is a screw drive module composed of a screw motor, a screw, a screw nut and a sliding mounting plate. The screw is connected to the driving end of the screw motor, the screw nut is screwed on the screw, the sliding mounting plate is fixedly connected to the screw nut, and the pickup part 42 is connected to the sliding mounting plate. When the screw motor drives the screw to rotate, the sliding mounting plate is driven to translate along the screw through the screw nut, thereby driving the pickup part 42 to translate synchronously.

[0081] like Figure 6 As shown, optionally, the transport mechanism 4 includes two picking parts 42, each of which includes a second lifting drive module 421 and a clamping assembly 422, wherein: the second lifting drive module 421 is connected to the movable part of the second translation drive module 41, and the clamping assembly 422 is connected to the movable part of the second lifting drive module 421. The second lifting drive module 421 is used to drive the clamping assembly 422 to rise and fall, so as to drive the clamping assembly 422 to clamp the battery cell from the transport station.

[0082] Since the two picking parts 42 can each independently carry out the gripping and carrying of a battery cell 100, the carrying efficiency of the carrying mechanism 4 is improved. For example, the two picking parts 42 can synchronously carry two cleaned battery cells to the flipping mechanism 5. For another example, the two picking parts 42 can synchronously pick up two battery cells that fail the thickness test and carry them to the NG buffer mechanism 7. For another example, when one of the picking parts 42 carries a cleaned battery cell to the flipping mechanism 5, the other picking part 42 picks up a battery cell that fails the thickness test and carries it to the NG buffer mechanism 7.

[0083] The second lifting drive module 421 can adopt various existing linear drive modules that can drive the gripping assembly 422 to rise and fall, such as a cylinder drive module composed of a cylinder, a slide rail and a slider, the slide rail is arranged in the vertical direction, the slider is slidably mounted on the slide rail and connected to the telescopic rod of the cylinder, the gripping assembly 422 is connected to the slider, and the cylinder drives the slider to slide along the slide rail to rise and fall, thereby driving the gripping assembly 422 to rise and fall. The gripping assembly 422 can be, for example, a gripping claw driven by a gripping claw cylinder.

[0084] like Figure 7As shown, optionally, the flip mechanism 5 includes a second mounting bracket 51, a flip plate 52, a flip driving member 53 and at least one clamping assembly 54, wherein: the flip driving member 53 is arranged on the second mounting bracket 51. The flip plate 52 is rotatably mounted on the second mounting bracket 51 and is in transmission connection with the flip driving member 53, and the clamping assembly 54 is arranged on the flip plate 52. The clamping assembly 54 is used to clamp the battery cell in an upright state transported by the transport mechanism 4, and the flip driving member 53 is used to drive the flip plate 52 to flip toward the unloading mechanism 6, so that the battery cell clamped on the clamping assembly 54 falls onto the unloading mechanism 6 in a horizontal state.

[0085] Figure 7 The turning mechanism 5 in the illustrated embodiment is provided with two clamping assemblies 54. Therefore, it can receive two battery cells synchronously carried by the carrying mechanism 4 and synchronously drop the two battery cells onto the unloading mechanism 6 in a horizontal state.

[0086] In some embodiments, the subsequent processing station has requirements on the orientation of the battery cell 100 conveyed by the unloading mechanism 6, for example, requiring the upward surface of the battery cell 100 to be the first side surface. Therefore, the flipping mechanism 5 needs to flip the battery cell 100 with the first side surface facing upward and place it on the unloading mechanism 6.

[0087] In order to meet this requirement, optionally, the clamping assembly 54 includes a flipping drive part 541 and a clamping part 542, wherein the flipping drive part 541 is arranged on the flip plate 52, and the clamping part 542 is connected to the driving end of the flipping drive part 541, the clamping part 542 is used to clamp the battery cell 100, and the flipping drive part 541 is used to drive the clamping part 542 to rotate so as to flip the battery cell 100 clamped on the clamping part 542, so as to ensure that when the battery cell 100 falls onto the unloading mechanism 6, the target surface (for example, the first side surface) faces upward.

[0088] The flipping driving part 541 may be, for example, a rotary motor, and the clamping part 542 may be, for example, a clamping claw driven by a clamping claw cylinder.

[0089] The present application is described in sufficient detail above with certain particularity. It should be understood by those skilled in the art that the description in the embodiments is merely exemplary, and all changes made without departing from the true spirit and scope of the present application should fall within the scope of protection of the present application. The scope of protection claimed in the present application is defined by the claims, rather than by the above description in the embodiments.
