Description

Technical Field

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

[0002] Before stacking the processed battery cells into battery cell modules, the processed battery cells need to be pre-processed such as appearance inspection, thickness inspection and cleaning. Specifically, the battery cells are driven by the conveyor line to pass through various pre-processing stations to receive corresponding pre-processing.

[0003] The existing battery cell pre-processing device is only equipped with one continuous conveyor line, so the appearance inspection mechanism set above or on the side of the conveyor line cannot inspect the bottom surface of the battery cell. In order to solve this problem, the existing processing solution is to add a flipping mechanism to the conveyor line, and the flipping mechanism will flip the battery cell during the appearance inspection process, so as to ensure that the appearance inspection mechanism can complete the inspection of all surfaces of the battery cell. The flipping operation prolongs the time consumption of appearance inspection, reduces the efficiency of battery cell processing, and easily causes damage to the battery cell. Utility Model Content

[0051] 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.

[0052] like Figure 1 As shown, the battery cell pretreatment device in the embodiment of the present application includes a first conveying mechanism 1, a second conveying mechanism 2, a handling mechanism 3, a first appearance inspection mechanism, a second appearance inspection mechanism and a material unloading mechanism.

[0053] The second conveying mechanism 2 is located behind the first conveying mechanism 1 , and the transfer mechanism 3 is arranged between the first conveying mechanism 2 and the second conveying mechanism 3 .

[0054] The first conveying mechanism 1 is used to carry and convey the battery cell 100 to the downstream. The battery cell 100 is carried on the first conveying mechanism 1 in an upright state. The first surface and the second surface of the battery cell 100 are in the direction of conveyance of the first conveying mechanism 1 ( Figure 1 The first side surface and the second side surface of the battery cell 100 are parallel to the direction indicated by the straight arrow L in the middle, and the first side surface and the second side surface of the battery cell 100 are perpendicular to the conveying direction of the first conveying mechanism 1.

[0055] The transport mechanism 3 is used to transport the battery cell 100 from the first transport mechanism 1 to the second transport mechanism 2. The second transport mechanism 2 is used to transport the battery cell 100 to the unloading station A. The battery cell 100 is carried on the second transport mechanism 2 in an upright state. The first surface and the second surface of the battery cell 100 are aligned with the transport direction of the second transport mechanism 2 ( Figure 1The first side surface and the second side surface of the battery cell 100 are parallel to the direction indicated by the straight arrow M in the middle, and the first side surface and the second side surface of the battery cell 100 are perpendicular to the conveying direction of the second conveying mechanism.

[0056] The first appearance inspection mechanism is disposed on the conveying path of at least one of the first conveying mechanism 1 and the second conveying mechanism 2, and is used to inspect the top end surface, the first surface and the second surface of the battery cell.

[0057] The second appearance inspection mechanism is disposed on the transport path of the transport mechanism 3 , and is used to inspect the bottom end surface, the first side surface and the second side surface of the battery cell.

[0058] The unloading mechanism is arranged at the side of the unloading station A, and is used to transfer the battery cells 100 that have passed the inspection from the unloading station A to the next station, and to transfer the battery cells 100 that have failed the inspection to the NG recycling station.

[0059] The cell pretreatment device in the embodiment of the present application is provided with two conveying mechanisms in sequence. When the conveying mechanism 3 conveys the cell 100 from the first conveying mechanism 1 to the second conveying mechanism 2, the bottom surface of the cell 100 is exposed from the first conveying mechanism 1 and inspected by the second appearance inspection mechanism. Therefore, by using the cell pretreatment device provided by the present application to perform the appearance inspection of the cell, there is no need to flip the cell. The appearance inspection of the entire surface of the cell can be completed during the conveying and handling process, thereby improving the inspection efficiency and reducing the risk of damage to the cell.

[0060] Optionally, the first appearance inspection mechanism includes a first inspection component and a second inspection component. The first inspection component can be arranged above the first conveying mechanism 1 or above the second conveying mechanism 2, and the first inspection component is used to inspect the top end surface of the battery cell. The second inspection component can be arranged on both sides of the first conveying mechanism 1 or on both sides of the second conveying mechanism 2, and is used to inspect the first surface and the second surface of the battery cell.

[0061] The first detection component and the second detection component can both adopt various known detection components capable of detecting the surface of the battery cell. For example, the first detection component includes a first camera, and the first camera performs surface detection on the top end surface of the battery cell 100 by imaging the top end surface of the battery cell 100. The second detection component includes a second camera and a third camera arranged opposite to each other, and when the battery cell 100 passes between the second camera and the third camera, the second camera and the third camera respectively image the first surface and the second surface of the battery cell 100 to perform surface detection on the first surface and the second surface of the battery cell 100.

[0062] Optionally, the second appearance inspection mechanism includes a third inspection component and a fourth inspection component. The third inspection component is used to inspect the bottom surface of the battery cell, and the fourth inspection component is used to inspect the first side and the second side of the battery cell. The third inspection component and the fourth inspection component can adopt various known inspection components that can inspect the surface of the battery cell. For example, the third inspection component includes a fourth camera, and the battery cell 100 passes over the fourth camera during transportation. The fourth camera performs surface inspection on the bottom surface of the battery cell 100 by imaging the bottom surface of the battery cell 100. The fourth inspection component includes a fifth camera and a sixth camera that are arranged relatively to each other. The battery cell 100 passes between the fifth camera and the sixth camera during transportation. The fifth camera and the sixth camera respectively image the first side and the second side of the battery cell 100 to perform surface inspection on the first side and the second side of the battery cell 100.

[0063] like Figure 1 As shown, optionally, the first conveying mechanism 1 includes a first conveying belt group 11, a first driving member 12 and a plurality of first limiting components 13, wherein: the first driving member 12 is configured to drive the first conveying belt group 11 to convey, the first conveying belt group 11 is used to carry the battery cell 100, and the plurality of first limiting components 13 are arranged along the conveying direction ( Figure 1 The first conveyor belt group 11 is installed at intervals in the direction indicated by the straight arrow L in the middle. Each group of first limit assemblies 13 includes two first limit blocks installed in parallel on the first conveyor belt group. There is a gap between the two first limit blocks for the vertical battery cells to be inserted. The first conveyor belt group 11 includes at least two first conveyor belts arranged side by side.

[0064] Compared with a conventional single conveyor belt, the first conveyor belt group 11 composed of at least two first conveyor belts arranged side by side has better transmission efficiency and stronger load-bearing capacity, which can ensure stable transportation of the battery cells 100. In addition, since each first conveyor belt in the first conveyor belt group 11 is narrower and lighter than a conventional single conveyor belt, it is easier to achieve tension, thereby further improving the transportation effect of the battery cells 100.

[0065] The first limiting assembly 13 disposed on the first conveyor belt assembly 11 realizes fixed limiting of the battery cell 100 , thereby preventing the battery cell 100 from tilting or sliding during the conveying process.

[0066] like Figures 1 to 3 As shown, optionally, the second conveying mechanism 2 includes a second conveying belt group 21, a second driving member 22 and a plurality of second limiting components 23, wherein: the second driving member 22 is configured to drive the second conveying belt group 21 to convey, the second conveying belt group 21 is used to carry the battery cell 100, and the plurality of second limiting components 23 are arranged along the conveying direction ( Figure 1The second conveyor belt group 21 is installed at intervals (in the direction indicated by the straight arrow M in the middle), and each group of second limiting components 23 includes two second limiting blocks installed in parallel on the second conveyor belt group 21, and there is a gap between the two second limiting blocks for the vertical battery cell 100 to be inserted. The second conveyor belt group 21 includes at least two second conveyor belts arranged side by side.

[0067] Similarly, compared with a conventional single conveyor belt, the second conveyor belt group 21 composed of at least two second conveyor belts arranged side by side has better transmission efficiency and stronger carrying capacity, which can ensure stable transportation of the battery cells 100. In addition, since each second conveyor belt in the second conveyor belt group 21 is narrower and lighter than a conventional single conveyor belt, it is easier to achieve tension, thereby further improving the transportation effect of the battery cells 100.

[0068] The second limiting assembly 23 disposed on the second conveyor belt assembly 21 realizes fixed limiting of the battery cell 100 to prevent the battery cell 100 from tilting or sliding during the conveying process.

[0069] Optionally, the second conveying mechanism 2 also includes a first guide rod 24 and a second guide rod 25 which are arranged in pairs on both sides of the second conveyor belt group 21 and extend along the conveying direction of the second conveyor belt group 21. The first guide rod 24 and the second guide rod 25 can guide and position the battery cell 100.

[0070] like Figure 1 As shown, optionally, the battery cell pretreatment device in the embodiment of the present application also includes a cleaning mechanism 4 arranged on the conveying path of the first conveying mechanism 1 and located in front of the first appearance inspection mechanism and the second appearance inspection mechanism, and the cleaning mechanism 4 is used to clean the battery cell 100 to be inspected on the first conveying mechanism 1.

[0071] By arranging a cleaning mechanism before the first appearance inspection mechanism and the second appearance inspection mechanism, the debris on the surface of the battery cell 100 to be inspected is cleaned, thereby preventing the debris from interfering with the appearance inspection of the first appearance inspection mechanism and the second appearance inspection mechanism.

[0072] like Figure 4 As shown, the cleaning mechanism 4 includes a first cleaning portion 41 and a second cleaning portion 42, wherein: the first cleaning portion 41 is located on the first side of the first conveying mechanism 1, and is used to clean the battery cells 100 on the first conveying mechanism 1 from the first side, and the second cleaning portion 42 is located on the second side of the first conveying mechanism 1, and is used to clean the battery cells 100 on the first conveying mechanism 1 from the second side.

[0073] Optionally, the first cleaning section 41 and the second cleaning section 42 have the same structure. Taking the first cleaning section 41 as an example, the first cleaning section 41 includes a first horizontal driving module 411, a first lifting driving module 412, a dust suction pipe 413 and a plasma cleaner 414, wherein: the first lifting driving module 412 is connected to the movable part of the first horizontal driving module 411, the dust suction pipe 413 is connected to the movable part of the first lifting driving module 412, the air inlet of the dust suction pipe 413 faces the first conveying mechanism 1, and the plasma cleaner 414 is arranged at the air inlet of the dust suction pipe 413. The first horizontal driving module 411 and the first lifting driving module 412 cooperate to drive the plasma cleaner 414 to move horizontally and vertically, so that the plasma cleaner 414 moves closely to the battery cell to remove impurities on the surface of the battery cell 100, and the dust suction pipe 413 is used to extract impurities processed by the plasma cleaner 414.

[0074] When the vertical battery cell is driven by the first conveying mechanism 1 to enter the cleaning station between the first cleaning section 41 and the second cleaning section 42, the plasma cleaner 414 of the first cleaning section 41 is close to the first surface of the battery cell 100, and the plasma cleaner 414 of the second cleaning section 42 is close to the second surface of the battery cell 100.

[0075] Next, the first horizontal driving module 411 and the first lifting driving module 412 cooperate to drive the plasma cleaner 414 to move horizontally and vertically, so that the corresponding plasma cleaner 414 moves closely to the first surface or the second surface of the battery cell to remove impurities on the surface of the battery cell 100. The dust suction pipe 413 removes the debris processed by the plasma cleaner 414.

[0076] Of course, the first cleaning part 41 and the second cleaning part 42 may also adopt cleaning mechanisms of other structures capable of cleaning the first surface or the second surface of the battery cell.

[0077] Optionally, the first cleaning section 41 and the second cleaning section 42 both include a regularization block 415 disposed above the plasma cleaner 414. When the first horizontal driving module 411 and the first lifting driving module 412 cooperate to drive the plasma cleaner 414 to perform plasma cleaning on the battery cell, the regularization block 415 synchronously moves close to the corresponding surface of the battery cell, thereby regularizing the battery cell 100 and scraping off the hard-to-clean dirt on the corresponding surface of the battery cell 100.

[0078] The first horizontal driving module 411 and the first lifting driving module 412 can both adopt various existing linear driving modules, such as a linear driving module composed of a cylinder, a slide rail and a slider, or a linear driving module composed of a motor, a screw and a screw nut.

[0079] Optionally, the cleaning mechanism 4 further includes an in-place detection component 43. When the battery cell 100 enters the cleaning station between the first cleaning section 41 and the second cleaning section 42, the in-place detection component 43 generates an in-place sensing signal, triggering the first cleaning section 41 and the second cleaning section 42 to start cleaning the battery cell 100.

[0080] Optionally, the arrival detection component 43 includes a light transmitter disposed on the first cleaning portion 41 and a light receiver disposed on the second cleaning portion 42. When there is no battery cell at the cleaning station, the light receiver can continuously receive the light emitted by the light transmitter. When the battery cell 100 enters the cleaning station, the light path between the light transmitter and the light receiver is blocked by the battery cell 100, and the light receiver cannot receive the light, thereby being triggered to generate an arrival sensing signal.

[0081] Continue to participate Figure 1 As shown, optionally, the battery cell pretreatment device in the embodiment of the present application further includes a thickness measuring mechanism 5 arranged on the conveying path of the second conveying mechanism 2. The battery cell 100 passes through the thickness measuring mechanism 5 driven by the second conveying mechanism 2, and the thickness measuring mechanism 5 is used to perform thickness detection on the battery cell 100. Of course, the thickness measuring mechanism 5 can also be arranged on the conveying path of the first conveying mechanism 1.

[0082] like Figure 5 As shown, optionally, the thickness measuring mechanism 5 includes a mounting bracket 51, a first driving member 52, a first pressure block 53, a second driving member 54 and a second pressure block 55, wherein: the first driving member 52 and the second driving member 54 are relatively arranged on the mounting bracket 51. The first pressure block 53 is connected to the driving end of the first driving member 52, and the second pressure block 55 is connected to the driving end of the second driving member 54. When the first pressure block 53 and the second pressure block 55 are in an initial position away from each other, a thickness measuring channel for the power core to enter is formed between the first pressure block 53 and the second pressure block 55. When the first driving member 52 and the second driving member 54 cooperate to drive the first pressure block 53 and the second pressure block 55 to move toward the middle, the first pressure block 53 and the second pressure block 55 are pressed against the first surface and the second surface of the battery cell 100 respectively.

[0083] The first driving member 52 and the second driving member 54 may be, for example, air cylinders, and the first pressing block 53 and the second pressing block 55 are connected to the ends of the telescopic rods of the air cylinders.

[0084] Optionally, the thickness measuring mechanism 5 measures the thickness of the battery cell 100 as follows:

[0085] In the initial state, the first pressing block 53 and the second pressing block 55 are in the initial position away from each other. At this time, the initial distance between the first pressing block 53 and the second pressing block 55 (ie, the width of the thickness measuring channel) is a predetermined value, set to A.

[0086] The second conveying mechanism 1 conveys the battery cell 100 placed in an upright state toward the thickness measuring mechanism 5. When the battery cell 100 enters the thickness measuring channel between the first pressing block 53 and the second pressing block 55, the second conveying mechanism 2 temporarily conveys it. The first driving member 52 and the second driving member 54 respectively drive the first pressing block 53 and the second pressing block 55 to move toward the middle until the first pressing block 53 and the second pressing block 55 are respectively pressed against the first surface and the second surface of the battery cell 100.

[0087] The driving stroke B of the first driving member 52 and the driving stroke C of the second driving member 54 are obtained, and the thickness T of the battery cell 100 is calculated based on the initial spacing A between the first pressing block 53 and the second pressing block 55, the driving stroke B of the first driving member 52 and the driving stroke C of the second driving member 54, T=ABC.

[0088] Optionally, the first driving member 52 and the second driving member 54 are both connected to the PLC controller signal, and the first driving member 52 and the second driving member 54 respectively send the corresponding driving stroke A and driving stroke B to the PLC controller, and the PLC controller calculates the thickness T of the battery cell 100 based on the initial spacing A between the first pressing block 53 and the second pressing block 55, the driving stroke B of the first driving member 52 and the driving stroke C of the second driving member 54.

[0089] After the thickness measurement operation of the battery cell 100 is completed, the first driving member 52 and the second driving member 54 respectively drive the first pressing block 53 and the second pressing block 55 to separate to both sides to release the battery cell 100 , and the second conveying mechanism 2 continues to convey the battery cell 100 .

[0090] Optionally, a pressure sensor 56 is further provided at the contact point between the driving end of the second driving member 54 and the second pressing block 55. When the pressing force between the second pressing block 55 and the second surface of the battery cell 100 reaches a predetermined value, the pressure sensor 56 is triggered to generate a stop signal, and the second driving member 54 stops driving the second pressing block 55.

[0091] Similarly, a pressure sensor may be provided at the contact point between the driving end of the first driving member 52 and the first pressing block 53. When the pressing force between the first pressing block 53 and the first surface of the battery cell 100 reaches a predetermined value, the pressure sensor is triggered to generate a stop signal, and the first driving member 52 stops driving the first pressing block 53.

[0092] like Figure 6 As shown, optionally, the unloading mechanism 6 includes a second translation drive module 61, a second lifting drive module 62, a rotation module 63 and a clamping assembly 64, wherein: the second lifting drive module 62 is connected to the movable part of the second translation drive module 61, the rotation module 63 is connected to the movable part of the second lifting drive module 62, and the clamping assembly 64 is connected to the movable part of the rotation module 63.

[0093] The second translation drive module 61 and the second lifting drive module 62 are used to cooperate in driving the clamping assembly 64 to translate and lift, so as to drive the clamping assembly 64 to transfer the qualified battery cells 100 from the unloading station to the next station, and to transfer the unqualified battery cells 100 to the NG recycling station. The rotation module 63 is used to drive the clamping assembly 64 to rotate during the transfer process to adjust the orientation of the battery cells 100.

[0094] The second translation drive module 61 and the second lifting drive module 62 can both adopt various existing linear drive modules, such as a linear drive module composed of a cylinder, a slide rail and a slider, or a linear drive module composed of a motor, a screw and a screw nut. The rotation module 63 can adopt various existing rotation drive modules, such as a rotation drive module composed of a motor, a driving gear and a driven gear. The clamping assembly 64 can be, for example, a clamping claw driven by a clamping claw cylinder.

[0095] The transport mechanism 3 in the embodiment of the present application may also adopt a structure similar to the unloading mechanism 6. When the transport paths of the first conveying structure 1 and the second conveying mechanism 2 are parallel, the transport mechanism 3 may not be provided with a rotating module. Of course, the unloading mechanism 6 and the transport mechanism 3 may also adopt other mechanisms capable of transporting the battery cells, such as a gripper driven by a robot arm.

[0096] 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.
