[0001] The present application relates to the technical field of battery, in particular to a cleaning device for battery module. BACKGROUND

[0002] At present, in the field of automatic battery module PACK (i.e. processing and assembling), when the busbar in the battery module is laser welded with the pole of the battery cell, smoke and slag will be generated, which will adhere to the surface of the busbar, not only affecting the appearance of the product, but also if not cleaned in time, the sharp corners of the slag may pierce the protective film of the battery cell, causing insulation failure of the battery module, and even the risk of short circuit.

[0003] The post-weld cleaning method of the existing battery module generally uses manual control of the dust collector to clean the smoke and slag. Since some slag is firmly adsorbed on the busbar, there is a problem of incomplete cleaning of the slag, which has a great safety hazard.

[0004] Therefore, it is urgent to develop a technology that can solve the above technical problems. SUMMARY

[0005] The purpose of the present application is to provide a cleaning device for battery module to solve the technical defects of the prior art.

[0006] To this end, the present application provides a cleaning device for battery module, comprising a rack, a cleaning assembly, a wire body assembly and a battery module tray assembly;

[0007] The cleaning assembly is arranged on the inner side of the upper part of the rack;

[0008] The wire body assembly horizontally penetrates through the lower part of the rack;

[0009] The battery module tray assembly is arranged on the wire body assembly;

[0010] The wire body assembly is used to carry the battery module tray assembly, convey the battery module tray assembly from right to left, and lift the battery module tray assembly upward when it is conveyed to the position below the cleaning assembly;

[0011] The cleaning assembly is used to perform surface cleaning operation on the battery module in the battery module tray assembly.

[0012] As can be seen from the technical solutions provided by the present application, compared with the prior art, the present application provides a cleaning device for battery module, which has a scientific structure design. By using the brush roller to separate the slag from the busbar in the battery module first, and then sucking the slag into the external dust removal equipment (such as conventional and mature dust removal machine), the cleaning device can ensure good cleaning effect and high cleaning efficiency, which has great practical significance.

[0013] By applying the present application, the smoke and slag particles adhered to the surface of the busbar in the battery module caused by the busbar and the cell pole after laser welding can be cleaned timely and reliably. BRIEF DESCRIPTION OF DRAWINGS

[0028] Referring to Figure 1 Figure 2 , Figures 3a to 3c , Figures 4a to 4b , Figure 5 , Figures 6a to 6b The present application provides a cleaning device for a battery module, comprising a rack 1, a cleaning assembly 2, a wire body assembly 3 and a battery module tray assembly 4.

[0029] The cleaning assembly 2 is arranged on the inner upper part of the rack 1;

[0030] The wire body assembly 3 transversely penetrates through the lower part of the rack 1;

[0031] The battery module tray assembly 4 is arranged on the wire body assembly 3;

[0032] The wire body assembly 3 is used to carry the battery module tray assembly 4 and convey the battery module tray assembly 4 from right to left, and when the battery module tray assembly 4 is conveyed to the position below the cleaning assembly 2, the battery module tray assembly 4 is lifted upward so that the bottom of the battery module tray assembly 4 is separated from the wire body 31 that the battery module tray assembly 4 has;

[0033] The cleaning assembly 2 is used to perform a surface cleaning operation on the battery module in the battery module tray assembly 4 (specifically, the surface of the busbar on the top of the battery module is cleaned of smoke dust and welding slag by the rotating brush roller 216).

[0034] It should be noted that the wire body assembly 3 can convey the battery module tray assembly 4 to move from right to left to different processing positions. Different processing positions can include multiple processing positions such as a battery module extrusion position, a battery module binding position, a battery module busbar welding position, and a battery module post-weld cleaning position, and the present application only specifically describes the structure of the battery module post-weld cleaning position.

[0035] In the present application, the whole of the rack 1 is of a frame type structure, and the top and bottom of the rack 1 are respectively provided with a cover plate and a bottom plate.

[0036] In the present application, as shown in Figure 2 、 Figures 3a to 3c The cleaning assembly 2 includes a cleaning and dust removal mechanism 21.

[0037] The cleaning and dust removal mechanism 21 includes a cleaning and dust removal mounting bracket 210, a stepping motor 211, a first synchronous wheel 212, a synchronous belt 213, a second synchronous wheel 214, a rotating shaft 215, and a brush roller 216.

[0038] The bottom of the cleaning and dust removal mounting bracket 210 is provided with a vertical support plate 2101 at both ends.

[0039] The rear side of the support plate 2101 on the rear side is fixedly connected to one end of a motor mounting plate 2102;

[0040] The other end of the motor mounting plate 2102 is fixedly provided with a stepping motor 211;

[0041] The output shaft of the stepping motor 211 is fixedly connected to the first synchronous wheel 212 after passing through the through hole reserved on the motor mounting plate 2102;

[0042] The lower parts of the two support plates 2101 are pivotally connected (i.e., rotatably connected) to the front and rear ends of the same rotating shaft 215;

[0043] The outer wall of the part of the rotating shaft 215 between the two support plates 2101 is sleeved with two brush rollers 216;

[0044] It should be noted that the opposite side of the two brush rollers 216 is also connected through a cylindrical connecting cylinder; the connecting cylinder is sleeved on the rotating shaft 215.

[0045] The rear end of the rotating shaft 215 protrudes from the rear side of the rear support plate 2101, and is sleeved with the second synchronous wheel 214;

[0046] The first synchronous wheel 212 and the second synchronous wheel 214 are connected through the synchronous belt 213.

[0047] The stepping motor 211 is used to drive the brush roller 216 to rotate, so that the brush roller 216 can separate the welding slag and dust from the surface of the busbar when it contacts the surface of the busbar of the battery module.

[0048] It should be noted that the first synchronous wheel 212 and the second synchronous wheel 214 are engaged with the synchronous belt 213.

[0049] It should be noted that the stepping motor 211 rotates to drive the first synchronous wheel 212 to rotate, and under the action of the synchronous belt 213, the second synchronous wheel 214 is driven to rotate, and finally the rotating shaft 215 is driven to rotate.

[0050] In specific implementation, the lower parts of the two support plates 2101 are pivotally connected (i.e., rotatably connected) to the front and rear ends of the same rotating shaft 215, and the specific structure design is as follows:

[0051] The lower parts of the two support plates 2101 are respectively provided with a bearing mounting hole at positions corresponding to the front and rear ends of the rotating shaft 215;

[0052] A bearing (such as a ball bearing) is fixedly arranged in each bearing mounting hole;

[0053] The inner rings of the two bearings are connected (fixedly connected) to the front and rear ends of the rotating shaft 215.

[0054] It should be noted that the number of brush rollers 216 is two, and they are fixed side by side on the rotating shaft 215, located at the rear side of the second synchronous wheel 214. The rotation of the rotating shaft 215 will drive the brush roller 216 to rotate together.

[0055] It should also be noted that when the brush roller 216 contacts the surface of the busbar in the battery module, if the brush roller 216 rotates, the dust and welding slag adsorbed on the busbar can be separated.

[0056] In specific implementation, the cleaning and dust removing mechanism 21 further comprises a dust suction cover 217

[0057] The left and right sides of each brush roller 216 are respectively provided with a dust cover 217, and the upper opening of one of the dust covers 217 is in communication with one end of a hollow dust suction pipe 2170;

[0058] The opposite side (i.e. the side facing the brush roller 216) of the two dust covers 217 on the left and right sides of each brush roller 216 is open;

[0059] The other end of the dust suction pipe 2170 is in communication with the dust suction port of an external dust removal device (such as a conventional and technically mature dust removal machine) through a hollow dust suction connecting pipe;

[0060] Further, the top of the two dust covers 217 is fixedly connected with the bottom of the cleaning and dust removal mounting bracket 210;

[0061] It should be noted that the external dust removal device is a mature and widely used device in the prior art, such as a dust removal machine or a dust collector. In specific implementation, the external dust removal device can adopt the industrial dust collector with dust suction function produced by Dongguan Hui Le Environmental Protection Co., Ltd. with model number VJFB-3.0(DZ).

[0062] It should be noted that the number of dust covers 217 is two, which are made of sheet metal welding. The shape of the dust cover 217 is similar to a cube (the bottom and the side facing the brush roller 216 are open), and the dust cover 217 has an open hollow cavity inside. Each brush roller 216 is located in the hollow cavity.

[0063] It should be noted that the tail of the dust cover 217 is welded with a circular pipe (i.e. the dust suction pipe 2170), which is connected with the external dust removal machine through the dust suction connecting pipe. The dust and slag separated from the busbar surface by the brush roller 216 can be removed in time by the external dust removal machine.

[0064] Further, the bottom of each dust cover 217 is provided with a brush baffle 218;

[0065] It should be noted that the function of the brush baffle 218 is to block the dust and slag brushed down when the brush roller 216 rotates, so as to prevent the dust and slag from flying out of the dust cover 217 and affecting the dust suction effect.

[0066] In specific implementation, the cleaning assembly 2 further includes a three-axis motion platform 22;

[0067] The three-axis motion platform 22 is used to drive the cleaning and dust removal mechanism 21 to move linearly in the front-back, left-right and / or up-down directions.

[0068] It should be noted that the three-axis motion platform 22 includes an X-axis motion module 221, a Y-axis motion module 222, and a Z-axis motion module 223; wherein the X-axis motion module 221 can move linearly in the front-back direction with the Y-axis motion module 222. The Y-axis motion module 222 can move linearly in the left-right direction with the Z-axis motion module 223; the cleaning and dust removing mechanism 21 is arranged on the Z-axis motion module 223. The Z-axis motion module 223 is used for moving linearly in the vertical up-down direction with the cleaning and dust removing mechanism 21.

[0069] Further, the top rear end of the cleaning and dust removing mounting bracket 210 in the cleaning and dust removing mechanism 21 is provided with a vertically distributed connecting plate 2103.

[0070] The connecting plate 2103 is connected with the Z-axis motion module 223 (specifically, a slider movable in the up-down direction).

[0071] It should be noted that the Z-axis motion module 223 can move linearly in the up-down direction with the cleaning and dust removing mechanism 21. That is, the cleaning and dust removing mechanism 21 can move linearly in the front-back, left-right, and up-down directions under the action of the three-axis motion platform 22.

[0072] It should be noted that the three-axis motion platform is a mature device of the prior art that has been widely applied. Specifically, the three-axis motion platform 22 can adopt a three-axis platform produced by Suzhou Touchpoint Robot Technology Co., Ltd. and having the function of driving an installed object (such as the cleaning and dust removing mechanism 21) to move linearly in the front-back, left-right, and up-down directions. The model of the three-axis platform is: GE8GE8GE8DC TH12-350Lx350x1200Rx200BC-G1. The three-axis platform includes an X-axis motion module, a Y-axis motion module, and a Z-axis motion module.

[0073] In the present application, as shown in Figure 4a The wire body assembly 3 includes a wire body 31, a blocking cylinder 32, and a jacking plate 33.

[0074] The wire body 31 includes two layers, which are divided into an upper layer and a lower layer.

[0075] It should be noted that the upper layer of the wire body 31 can transport the battery module tray assembly 4 to move from right to left to different processing positions, and the lower layer of the wire body 31 can transport the transfer tray 41 in the battery module tray assembly 4 to move from left to right.

[0076] The blocking cylinder 32 is fixed on the upper layer of the wire body 31 and located at the left side of the jacking plate 33.

[0077] Specifically, the bottom center position of the jacking plate 33 is connected with the power output end (such as a piston rod) of a jacking cylinder 330 in linkage.

[0078] The jacking cylinder 330 is used to jack up the battery module tray assembly 4 (specifically, to a preset height) when the battery module tray assembly 4 is moved to the battery module post-weld cleaning position (i.e., a position below the cleaning dust removal mechanism 21 of the cleaning assembly 2) by the wire body assembly 3, so that the bottom of the battery module tray assembly 4 is separated from the wire body 31 in the wire body assembly 3 (at the same time, the battery module tray assembly 4 is also moved to the direction of the cleaning dust removal mechanism 21 of the cleaning assembly 2, i.e., upward movement).

[0079] It should be noted that the jacking plate 33 is provided below the jacking cylinder 330, which can jack up the jacking plate 33 and the battery module tray assembly 4 above the jacking plate 33 together, so that the battery module tray assembly 4 is separated from the wire body 31.

[0080] Specifically, referring to Figure 4b As shown, the jacking cylinder 330 includes a jacking cylinder cylinder body 3301 and a piston rod;

[0081] The lower end of the upper portion of the wire body 31 is fixedly provided with a jacking cylinder cylinder body mounting plate 331;

[0082] The bottom of the jacking cylinder cylinder body mounting plate 331 is provided with the jacking cylinder cylinder body 3301;

[0083] The jacking plate 33 is provided directly above the jacking cylinder cylinder body mounting plate 331;

[0084] The piston rod protruding from the top side of the jacking cylinder cylinder body 3301 is fixedly connected to the bottom of the jacking plate 33 through a cylinder joint 3302 after passing through a vertical through hole reserved on the jacking cylinder cylinder body mounting plate 331;

[0085] It should be noted that the main components of the jacking cylinder 330 include the jacking cylinder cylinder body 3301 and the piston rod; the jacking cylinder cylinder body mounting plate is fixed on the upper layer of the wire body 31; the cylinder joint 3302 is connected to the piston rod of the jacking cylinder, and is fixedly connected with the jacking plate 33. When the piston rod of the jacking cylinder 330 moves upward, the jacking plate 33 will move upward together.

[0086] Further, the bottom of the jacking plate 33 is provided with two vertically distributed guide columns 332 at the left and right ends, respectively;

[0087] The jacking cylinder cylinder body mounting plate 331 is provided with a vertically distributed guide through hole at a position corresponding to each guide column 332, respectively;

[0088] Each guide through hole is provided with a hollow guide sleeve 333;

[0089] Each guide column 332 is vertically inserted into the center through hole of a guide sleeve 333, respectively.

[0090] It should be noted that, in specific implementation, the jacking cylinder 330 is a mature and well-known cylinder in the prior art, for example, a cylinder produced by AIRTAC International Group, with a brand of AIRTAC and a model of SDA100X60SB can be adopted.

[0091] It should be noted that the blocking cylinder 32 is used to block or release the battery module tray assembly 4. When the battery module tray assembly 4 reaches the battery module post-weld cleaning station, it is blocked, and when the processing at the station is completed, it is released to flow into the next station.

[0092] In specific implementation, the jacking plate 33 has a jacking positioning pin 34 at each of the left and right ends at the top thereof.

[0093] The jacking positioning pin 34 is used to be inserted into a positioning shaft sleeve (specifically a positioning copper sleeve) 415 on the transfer tray 41 of the battery module tray assembly 4.

[0094] It should be noted that the jacking positioning pin 34 is two in number and is located at the left front corner and the right rear corner of the jacking plate 33 respectively. The jacking positioning pin 34 is used to accurately position the battery module tray assembly 4 on the jacking plate 33.

[0095] It should be noted that the line body 31 is a mature and well-known line body in the prior art, which is a line body on an existing assembly line and is used to convey (laterally convey left and right) the battery module tray assembly 4 thereon.

[0096] It should be noted that, in specific implementation, the blocking cylinder 32 is a mature and well-known cylinder in the prior art, for example, a blocking cylinder produced by AIRTAC International Group, with a brand of AIRTAC and a model of TTH63X30SKF can be adopted, which is used to block or release the battery module tray assembly 4.

[0097] It should be noted that the line body 31 is a mature and well-known line body in the prior art, which is a line body on an existing assembly line and is used to convey (for example, laterally convey left and right) the battery module tray assembly 4 thereon. For example, the line body 11 can be a tray conveyor produced by Dalian Meidele Industrial Automation Co., Ltd., with a model of PTS5.

[0098] In the present application, referring to Figure 5 It is shown that the battery module tray assembly 4 includes a transfer tray 41 and a battery module 42.

[0099] The battery module 42 is located at the top of the transfer tray 41.

[0100] In specific implementation, referring to Figure 6a , Figure 6bAs shown, the transport tray 41 comprises a tray body 411, an insulation plate 412, a first side edge positioning frame 413, a clamping assembly 414 and positioning bushings (specifically positioning copper bushings) 415;

[0101] The insulation plate 412 is arranged at the top middle position of the tray body 411;

[0102] The battery module 42 is arranged at the top of the insulation plate 412;

[0103] It should be noted that the insulation plate 412 is made of insulating material, and the bottom of the battery module 42 is arranged on the insulation plate 412.

[0104] Further, the first side edge positioning frame is arranged at the rear side of the tray body 411;

[0105] It should be noted that the rear side of the battery module 42 is in contact with the first side edge positioning frame 413.

[0106] The clamping assembly 414 is arranged at the front side of the tray body 411;

[0107] It should be noted that the front side of the battery module 42 is in contact with the clamping assembly 414.

[0108] The battery module 42 is arranged between the side edge positioning frame 413 and the clamping assembly 414.

[0109] Further, the tray body 411 is provided with four positioning bushings (specifically positioning copper bushings) 415 at the positions close to the four corners of the insulation plate 412;

[0110] It should be noted that the number of positioning bushings (specifically positioning copper bushings) 415 is four, which are symmetrically arranged at the positions close to the four corners of the insulation plate 412.

[0111] It should be noted that when the jacking plate 33 jacks up the battery module tray assembly 4, the jacking positioning pin 34 on the jacking plate 33 will be inserted into the positioning bushing (specifically the positioning copper bushing) 415, so that the battery module tray assembly 4 is precisely positioned on the jacking plate 33.

[0112] In specific implementation, the clamping assembly 414 comprises a second side edge positioning frame 4141;

[0113] The second side edge positioning frame 4141 is fixedly arranged at the top front side of the tray body 411;

[0114] A push plate 4142 is arranged behind the second side edge positioning frame 4141;

[0115] Four longitudinal light shafts 4143 (i.e. cylindrical shafts) are arranged on the side of the push plate 4142 facing the second side edge positioning frame 4141;

[0116] The second side positioning frame 4141 is provided with a linear bearing at a position corresponding to each optical axis 4143;

[0117] The four optical axes 4143 correspond to the four linear bearings.

[0118] It should be noted that the four linear bearings include two first linear bearings 4144 in the middle and two second linear bearings 4145 on the left and right. The first linear bearings 4144 have hollow guide cylinders that protrude more forward than the second linear bearings 4145, which can enhance the guiding performance and effect.

[0119] It should be noted that for the present application, the cooperation of the optical axis and the linear bearing allows the push plate to move linearly in the forward and backward directions. When the battery module 42 is placed between the push plate of the clamping assembly 414 and the first side positioning frame 413, the battery module 42 with a larger width will push the push plate 4142 to move forward, and at the same time, the push plate 4142 will also push the battery module 42 to move backward to approach the first side positioning frame 413, thereby clamping the battery module 42.

[0120] It should be noted that the two first linear bearings 4144 are mature mechanical components of existing technology that have been widely applied, for example, the LMP12-D12 linear bearing produced by Dongguan Yiheda Automation Co., Ltd. can be used.

[0121] It should be noted that the two second linear bearings 4145 are mature mechanical components of existing technology that have been widely applied, for example, the LME13-D12 linear bearing produced by Dongguan Yiheda Automation Co., Ltd. can be used.

[0122] Further, the left and right ends of the second side positioning frame 4141 are respectively provided with a longitudinally penetrating elbow clamp mounting hole;

[0123] An elbow clamp 4146 is mounted on each elbow clamp mounting hole;

[0124] The elbow clamp 4146 has a longitudinally distributed push-pull rod rear end that is fixedly connected to the front side of the push plate 4142.

[0125] It should be noted that the elbow clamp 4146 is a mature mechanical component of existing technology that has been widely applied, for example, the WDC36202M quick clamp produced by Dongguan Yiheda Automation Co., Ltd. can be used. By operating the handle on it, the push plate can be moved forward and backward, which is beneficial to the push plate clamping the battery module backward and ensures the positioning effect of the battery module.

[0126] Specifically, referring to Figure 5 As shown in the figure, the battery module 42 comprises a plurality of battery cells 421;

[0127] The plurality of battery cells 421 are connected in parallel, in series, or in series-parallel (i.e., a combination of series and parallel connection) ;

[0128] It should be noted that the poles of the plurality of battery cells 421 are connected together in sequence through a plurality of busbars 422.

[0129] It should be noted that the battery module is arranged by a plurality of battery cells 421 arranged in a certain series or parallel arrangement;

[0130] It should be noted that for the battery module, the specific way of connecting a plurality of battery cells in series, in parallel, and in series-parallel is a conventional known technology in the existing battery technology field, which will not be described here.

[0131] It should be noted that as is known, each battery cell 421 contains a positive pole and a negative pole, and the battery cell poles need to be connected together through the busbar 422 to ensure normal operation of the battery module 42. To ensure that the poles are firmly connected to the busbar 422, laser welding is generally used to weld the poles of the battery cell 421 and the busbar 422 together.

[0132] It should be noted that welding of the poles and the busbar will generate smoke and slag, although there is a dust suction device in the battery module welding station, but a small amount of smoke and slag will be adsorbed to the surface of the busbar, and the device of the present application needs to be used to clean the surface of the busbar after welding.

[0133] In order to more clearly understand the technical solutions of the present application, the working principle of the present application is described below.

[0134] First, the battery module tray assembly 4 is conveyed from right to left by the wire body assembly 3, so that the battery module tray assembly 4 moves from right to left to the battery module post-weld cleaning station (i.e., the position below the cleaning dust removal mechanism 21 of the cleaning assembly 2) ;

[0135] Then, under the action of the blocking cylinder 32, the battery module tray assembly 4 stops moving, the lifting plate 33 is lifted upward, the battery module tray assembly 4 is separated from the wire body 31, and the positioning pin 34 is inserted into the positioning shaft sleeve 415 in the battery module tray assembly 4, so that the battery module tray assembly 4 is accurately positioned;

[0136] Then, through the three-axis motion platform 22, the cleaning and dust removing mechanism 21 is driven to move linearly in the front-back, left-right and / or up-down directions, so that the brush roller 216 in the cleaning and dust removing mechanism 21 is in contact with the busbar surface of the top of the battery module (for example, the leftmost position) in the battery module tray assembly 4, that is, reaches the working position (for example, the working mode of an embodiment can be: if the battery module is below the front of the cleaning and dust removing mechanism 21, then the X-axis motion module 221 moves forward with the Z-axis motion module 223, and the Z-axis motion module 223 moves downward with the cleaning and dust removing mechanism 21 to reach the working position of the brush roller 216), then the stepping motor 211 drives the brush roller 216 to rotate, under the action of the rotation of the brush roller 216, the smoke and slag are separated from the busbar 422, then under the action of the dust suction cover 217 and the dust remover, the separated smoke and slag are sucked into the dust remover located outside. Then, the Y-axis motion module 222 moves the cleaning and dust removing mechanism 21 to the right, and sequentially cleans the smoke and slag on each busbar 422, when all the smoke and slag on the busbars 422 are cleaned, the jacking plate 33 ends the jacking, the battery module tray assembly 4 falls back to the line body 31, the blocking cylinder 32 releases, and the battery module tray assembly 4 flows to the next working position.

[0137] The above is only the preferred embodiment of the present application, it should be noted that for those skilled in the art, without departing from the principles of the present application, can make several improvements and refinements, these improvements and refinements should also be considered as the protection scope of the present application.
