Description

Technical Field

[0001] This utility model relates to the field of battery technology, and in particular to a cleaning device for battery modules. Background Technology

[0002] Currently, in the field of automated battery module PACK (i.e., processing and assembly), when the busbar and cell terminals in the battery module are laser welded, fumes and welding slag are generated. The fumes and welding slag adhere to the surface of the busbar, which not only affects the appearance of the product, but also, if not cleaned in time, the welding slag will fall between the two cells in the battery module. The sharp corners of the welding slag may puncture the protective film of the cell, causing insulation failure of the battery module, or even the risk of short circuit.

[0003] The current method for cleaning battery modules after welding generally involves manually controlling a vacuum cleaner to remove fumes and welding slag. However, because some welding slag adheres firmly to the busbars, there is a problem of incomplete cleaning, which poses a significant safety hazard.

[0004] Therefore, there is an urgent need to develop a technology that can solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this invention is to address the technical deficiencies of existing technologies by providing a cleaning device for battery modules.

[0006] Therefore, this utility model provides a battery module cleaning device, including a frame, a cleaning component, a line component, and a battery module tray component; The cleaning components are located on the upper inner side of the rack; The line assembly runs horizontally through the lower part of the frame; The battery module tray assembly is mounted on the line assembly; The line assembly is used to carry the battery module tray assembly and transport the battery module tray assembly from right to left. When it is transported to the position below the cleaning assembly, the battery module tray assembly is lifted upward. A cleaning component is used to perform surface cleaning operations on the battery modules in the battery module tray assembly.

[0007] As can be seen from the technical solution provided by this utility model above, compared with the prior art, this utility model provides a cleaning device for battery modules. Its structure is scientifically designed. By using a brush roller to first separate the welding slag from the busbar in the battery module, and then sucking the welding slag into an external dust removal device (such as a conventional and technologically mature dust removal machine), it ensures a good cleaning effect and high cleaning efficiency, which has significant practical significance.

[0008] By applying this invention, the dust and welding slag particles adhering to the surface of the busbar in the battery module after laser welding of the busbar and the cell terminal can be cleaned in a timely and reliable manner. Attached Figure Description

[0014] See Figure 1 Figure 2 , Figures 3a to 3c , Figures 4a to 4b , Figure 5 , Figures 6a to 6b This utility model provides a battery module cleaning device, including a frame 1, a cleaning component 2, a line component 3, and a battery module tray component 4; The cleaning component 2 is located on the upper inner side of the rack 1; Line assembly 3 extends laterally through the lower part of frame 1; Battery module tray assembly 4 is mounted on line body assembly 3; Line assembly 3 is used to carry battery module tray assembly 4 and transport battery module tray assembly 4 from right to left. When it is transported to the position below cleaning assembly 2, it lifts battery module tray assembly 4 upward so that the bottom of battery module tray assembly 4 is separated from its line 31. Cleaning component 2 is used to perform surface cleaning operations on the battery modules in the battery module tray assembly 4 (specifically, to clean the surface of the busbar on the top of the battery module by rotating the brush roller 216 to remove dust and welding slag).

[0015] It should be noted that the line assembly 3 can transport the battery module tray assembly 4 from right to left to different processing stations. The different processing stations may include multiple stations such as the battery module extrusion station, the battery module binding station, the battery module busbar welding station, and the battery module post-weld cleaning station. This utility model only describes the structure of the battery module post-weld cleaning station in detail.

[0016] In this utility model, the frame 1 is a frame structure, and the top and bottom of the frame 1 are respectively provided with a cover plate and a bottom plate.

[0017] In this utility model, see Figure 2 , Figures 3a to 3c As shown, cleaning component 2 includes a cleaning and dust removal mechanism 21; The cleaning and dust removal mechanism 21 includes a cleaning and dust removal mounting bracket 210, a stepper motor 211, a first synchronous pulley 212, a synchronous belt 213, a second synchronous pulley 214, a rotating shaft 215, and a brush roller 216; At the bottom front and rear ends of the cleaning and dust removal mounting bracket 210, there is a vertically distributed support plate 2101. The upper rear part of the support plate 2101 located at the rear is fixedly connected to one end of a motor mounting plate 2102; A stepper motor 211 is fixedly installed on the front side of the other end of the motor mounting plate 2102; The output shaft of the stepper motor 211 passes through the pre-drilled hole on the motor mounting plate 2102 and is fixedly connected to the first synchronous pulley 212; 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. The rotating shaft 215 is located on the outer wall between the two support plates 2101, and two brush rollers 216 are fitted thereon. It should be noted that the two brush rollers 216 are also connected on opposite sides by a cylindrical connecting cylinder; the connecting cylinder is fitted onto the rotating shaft 215.

[0018] The rear end of the pivot 215 protrudes from the rear side of the support plate 2101 located at the rear, and is fitted with a second synchronous pulley 214; The first synchronous pulley 212 and the second synchronous pulley 214 are connected by a synchronous belt 213; Stepper motor 211 is used to drive brush roller 216 to rotate, so that when brush roller 216 comes into contact with the busbar surface of the battery module, it can separate welding slag and fumes from the busbar surface.

[0019] It should be noted that the first synchronous pulley 212 and the second synchronous pulley 214 mesh with the synchronous belt 213.

[0020] It should be noted that when the stepper motor 211 rotates, it drives the first synchronous pulley 212 to rotate, which in turn drives the second synchronous pulley 214 to rotate under the action of the synchronous belt 213, and finally drives the rotating shaft 215 to rotate.

[0021] In terms of 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. The specific structural design is as follows: The lower part of the two support plates 2101 is provided with a bearing mounting hole at a position corresponding to the front and rear ends of the rotating shaft 215; Each bearing mounting hole contains a fixed bearing (e.g., a ball bearing). The inner rings of the two bearings are connected to the front and rear ends of the rotating shaft 215 (fixed connection).

[0022] It should be noted that there are two brush rollers 216, which are fixed side by side on the rotating shaft 215, located behind the second synchronous wheel 214. The rotation of the rotating shaft 215 will drive the brush rollers 216 to rotate together.

[0023] It should also be noted that when the brush roller 216 comes into contact with the busbar surface in the battery module, if the brush roller 216 rotates, it can remove the dust and welding slag adsorbed on the busbar.

[0024] In specific implementation, the cleaning and dust removal mechanism 21 also includes a dust suction hood 217. Each brush roller 216 has a dust collection hood 217 on its left and right sides, and the upper opening of one of the dust collection hoods 217 is connected to one end of a hollow dust collection pipe 2170. The two dust covers 217 on both sides of each brush roller 216 have openings on opposite sides (i.e., the side facing the brush roller 216); The other end of the suction pipe 2170 is connected to the suction port of an external dust removal device (such as a conventional, technologically mature dust collector) through a hollow suction connection pipe; Furthermore, the tops of the two dust hoods 217 are fixedly connected to the bottom of the cleaning and dust removal mounting bracket 210; It should be noted that external dust removal equipment is existing, mature, and widely used equipment, such as dust collectors or dust removal machines. Specifically, external dust removal equipment can be the VJFB-3.0(DZ) industrial dust collector with dust collection function produced by Dongguan Huile Environmental Protection Co., Ltd.

[0025] It should be noted that there are two dust hoods 217, which are welded from sheet metal. The shape of the dust hood 217 is similar to a cube (open at the bottom and on the side facing the brush roller 216), and the inside of the dust hood 217 has an open hollow cavity. Each brush roller 216 is located in one of the hollow cavities.

[0026] It should be noted that a circular pipe (i.e., suction pipe 2170) is welded to the tail of the dust hood 217. This pipe is connected to an external dust collector through a dust collection connection pipe. The external dust collector absorbs the smoke and welding slag, and can promptly remove the welding slag and smoke separated from the manifold surface by the brush roller 216.

[0027] Furthermore, each dust hood 217 is provided with a brush baffle 218 at its bottom; It should be noted that the function of the brush baffle 218 is to block the smoke and welding slag that are brushed off when the brush roller 216 rotates, so as to prevent the smoke and welding slag from flying out of the dust collection hood 217 and affecting the dust collection effect.

[0028] In practice, the cleaning component 2 also includes a three-axis motion platform 22; The three-axis motion platform 22 is used to drive the cleaning and dust removal mechanism 21 to make linear movements in the front-back, left-right and / or up-down directions.

[0029] 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 along with the Y-axis motion module 222. The Y-axis motion module 222 can move linearly in the left-right direction along with the Z-axis motion module 223; the cleaning and dust removal mechanism 21 is mounted on the Z-axis motion module 223. The Z-axis motion module 223 is used to move the cleaning and dust removal mechanism 21 linearly in the vertical direction.

[0030] Furthermore, a vertically distributed connecting plate 2103 is provided at the top rear end of the cleaning and dust removal mounting bracket 210 in the cleaning and dust removal mechanism 21; The connecting plate 2103 is connected to the Z-axis motion module 223 (specifically, the slider that can move in the up and down direction).

[0031] It should be noted that the Z-axis motion module 223 can move the cleaning and dust removal mechanism 21 in a straight line in the vertical direction. In other words, under the action of the three-axis motion platform 22, the cleaning and dust removal mechanism 21 can move in a straight line in the forward, backward, left, right, and vertical directions.

[0032] It should be noted that the three-axis motion platform is a mature and widely used technology. Specifically, the three-axis motion platform 22 can be a three-axis platform manufactured by Suzhou Touchpoint Robotics Technology Co., Ltd., which has the function of driving objects mounted on it (such as the cleaning and dust removal mechanism 21) to perform linear motion in the forward, backward, left, right, and up / down directions. The model of this three-axis platform is: GE8GE8GE8DCTH12-350Lx350x1200Rx200BC-G1. This three-axis platform includes an X-axis motion module, a Y-axis motion module, and a Z-axis motion module.

[0033] In this utility model, see Figure 4a As shown, the line assembly 3 includes a line 31, a blocking cylinder 32, and a lifting plate 33; The line body 31 consists of two layers, namely an upper layer and a lower layer.

[0034] It should be noted that the upper layer of the line 31 can transport the battery module tray assembly 4 from right to left to different processing positions, and the lower layer of the line 31 can transport the transfer tray 41 in the battery module tray assembly 4 from left to right.

[0035] The blocking cylinder 32 is fixed on the upper layer of the line body 31 and is located on the left side of the lifting plate 33; In practice, the bottom center of the lifting plate 3 is linked to the power output end (e.g., piston rod) of a lifting cylinder 330. The lifting cylinder 330 is used to lift the battery module tray assembly 4 upward (specifically, to a preset height) when the battery module tray assembly 4 is moved by the line assembly 3 to the post-welding cleaning station of the battery module (i.e., below the cleaning and dust removal mechanism 21 of the cleaning assembly 2), so that the bottom of the battery module tray assembly 4 is separated from the line 31 in the line assembly 3 (at the same time, it also moves towards the cleaning and dust removal mechanism 21 of the cleaning assembly 2, i.e., moves upward). It should be noted that a lifting cylinder 330 is provided below the lifting plate 33, which can lift the lifting plate 33 and the battery module tray assembly 4 above the lifting plate 33 together, so that the battery module tray assembly 4 is separated from the line body 31.

[0036] For specific implementation details, see [link to implementation details]. Figure 4b As shown, the lifting cylinder 330 includes a lifting cylinder body 3301 and a piston rod; A lifting cylinder mounting plate 331 is fixedly installed at the lower end of the upper part of the line body 31. At the bottom of the lifting cylinder mounting plate 331, a lifting cylinder body 3301 is provided; A lifting plate 33 is provided directly above the cylinder body mounting plate 331 of the lifting cylinder; The piston rod extending from the top side of the lifting cylinder body 3301 passes through a pre-drilled vertical through hole on the lifting cylinder body mounting plate 331 and is then fixedly connected to the bottom of the lifting plate 33 via a cylinder connector 3302. It should be noted that the main components of the lifting cylinder 330 include the lifting cylinder body 3301 and the piston rod; the lifting cylinder body mounting plate is fixed on the upper layer of the line body 31; the cylinder connector 3302 is connected to the piston rod of the lifting cylinder and is fixedly connected to the lifting plate 33. When the piston rod of the lifting cylinder 330 moves upward, it will drive the lifting plate 33 to move upward together.

[0037] Furthermore, two vertically distributed guide columns 332 are respectively provided at the bottom left and right ends of the lifting plate 33; The lifting cylinder mounting plate 331 is provided with a vertically distributed guide through hole at the position corresponding to each guide post 332; Each guide hole is provided with a hollow guide sleeve 333; Each guide post 332 is vertically inserted into the central through hole of a guide sleeve 333.

[0038] It should be noted that, in practice, the lifting cylinder 330 is a well-established and technically mature cylinder, such as the SDA100X60SB cylinder produced by Airtac International Group, branded as Airtac.

[0039] It should be noted that the function of the blocking cylinder 32 is to either block or allow the battery module tray assembly 4 to pass. When the battery module tray assembly 4 reaches the post-weld cleaning station of the battery module, it is blocked; when the processing at that station is completed, it is allowed to pass, allowing it to flow to the next station.

[0040] In practice, a lifting positioning pin 34 is provided at each of the left and right ends of the top of the lifting plate 33; The lifting positioning pin 34 is used to correspond to the positioning bushing (specifically the positioning copper bushing) 415 on the transfer tray 41 of the battery module tray assembly 4.

[0041] It should be noted that there are two lifting positioning pins 34, located at the front left corner and the rear right corner of the lifting plate 33, respectively. The function of the lifting positioning pins 34 is to accurately position the battery module tray assembly 4 on the lifting plate 33.

[0042] It should be noted that line 31 is a well-established and technically mature production line, and is a production line on an existing production line, used to transport (transport horizontally and left and right) the battery module tray assembly 4 on it.

[0043] It should be noted that, in specific implementation, the blocking cylinder 32 is a well-established and known cylinder with mature existing technology. For example, a blocking cylinder with the brand name AirTAC and model number TTH63X30SKF produced by AirTAC International Group can be used. Its function is to block or allow the battery module tray assembly 4 to pass.

[0044] It should be noted that line 31 is a well-established and technologically mature production line, used to transport (e.g., laterally or left-right) the battery module tray assembly 4. For example, line 11 can be a tray conveyor of model PTS5 manufactured by Dalian Medela Industrial Automation Co., Ltd.

[0045] In this utility model, see Figure 5 As shown, the battery module tray assembly 4 includes a transfer tray 41 and a battery module 42; Battery module 42 is located on top of transfer tray 41.

[0046] For specific implementation details, see [link to implementation details]. Figure 6a , Figure 6b As shown, the transfer pallet 41 includes a pallet body 411, an insulating plate 412, a first side positioning frame 413, a clamping assembly 414, and a positioning bushing (specifically a positioning copper bushing) 415. Insulating plate 412 is located at the top center of the tray body 411; The battery module 42 is disposed on top of the insulating plate 412; It should be noted that the insulating plate 412 is made of insulating material, and the bottom of the battery module 42 is set on the insulating plate 412.

[0047] Furthermore, the first side positioning frame is located on the rear side of the pallet body 411; It should be noted that the rear side of the battery module 42 contacts the first side positioning bracket 413.

[0048] Clamping assembly 414 is disposed on the front side of pallet body 411; It should be noted that the front side of the battery module 42 is in contact with the clamping assembly 414.

[0049] The battery module 42 is positioned between the side positioning bracket 413 and the clamping assembly 414.

[0050] Furthermore, the pallet body 411 is provided with four positioning bushings (specifically positioning copper bushings) 415 at the four corners near the insulating plate 412; It should be noted that there are four positioning bushings (specifically, positioning copper bushings) 415, which are symmetrically arranged at the four corners near the insulating plate 412.

[0051] It should be noted that when the lifting plate 33 lifts the battery module tray assembly 4 upward, the lifting positioning pin 34 on the lifting plate 33 will be inserted into the positioning bushing (specifically the positioning copper bushing) 415, thereby accurately positioning the battery module tray assembly 4 on the lifting plate 33.

[0052] In specific implementation, the clamping assembly 414 includes a second side positioning frame 4141; The second side positioning frame 4141 is fixedly installed on the top front side of the pallet body 411; A push plate 4142 is provided directly behind the second side positioning frame 4141; The push plate 4142 has four longitudinally distributed optical axes 4143 (i.e. cylindrical axes) on the side facing the second side positioning frame 4141. The second side positioning frame 4141 is provided with a linear bearing at a position corresponding to each optical axis 4143; The four optical axes 4143 are inserted through the four linear bearings.

[0053] It should be noted that the four linear bearings include two first linear bearings 4144 located in the middle and two second linear bearings 4145 located on the left and right sides. Among them, the first linear bearings 4144 have hollow guide cylinders that protrude further forward than the second linear bearings 4145, which can enhance the guiding performance and effect.

[0054] It should be noted that, in this invention, the optical axis and linear bearing work together to ensure that the push plate can only move linearly in the front-back direction. When the battery module 42 is placed between the push plate of the clamping assembly 414 and the first side positioning frame 413, the wider battery module 42 will push the push plate 4142 forward, and at the same time, the push plate 4142 will also push the battery module 42 backward toward the first side positioning frame 413, thereby clamping the battery module 42.

[0055] It should be noted that the two first linear bearings 4144 are existing mature mechanical components that have been widely used. For example, linear bearings of model LMP12-D12 produced by Dongguan Yiheda Automation Co., Ltd. under the Yiheda brand can be used.

[0056] It should be noted that the two second linear bearings 4145 are existing, mature, and widely used mechanical components. For example, linear bearings of model LME13-D12 produced by Dongguan Yiheda Automation Co., Ltd. under the Yiheda brand can be used.

[0057] Furthermore, a longitudinally penetrating elbow clamp mounting hole is provided at each of the left and right ends of the second side positioning bracket 4141. Each elbow clamp mounting hole has an elbow clamp 4146 installed; The elbow clamp 4146 has a longitudinally distributed push-pull rod at the rear end, which is fixedly connected to the front side of the push plate 4142.

[0058] It should be noted that the elbow clamp 4146 is a mature and widely used mechanical component. For example, a quick clamp with the Yiheda brand and model number WDC36202M produced by Dongguan Yiheda Automation Co., Ltd. can be used. By operating the handle on it, the push plate can be driven to move back and forth, which helps the push plate to clamp the battery module backward and ensure the positioning effect of the battery module.

[0059] For specific implementation details, see [link to implementation details]. Figure 5 As shown, the battery module 42 includes multiple battery cells 421; Multiple battery cells 421 are connected in parallel, series, or series-parallel (i.e., a combination of series and parallel connections); It should be noted that the terminals of multiple battery cells 421 are connected together in sequence through multiple busbars 422.

[0060] It should be noted that the battery module is composed of several cells 421 arranged in a certain series or parallel manner; It should be noted that the specific methods for connecting multiple cells in series, parallel, or in a series-parallel configuration for battery modules are common and well-known technologies in the existing battery technology field, and will not be elaborated here.

[0061] It should be noted that, as is well known, each battery cell 421 contains a positive terminal and a negative terminal. The battery cell terminals need to be connected together through a busbar 422 to ensure the normal operation of the battery module 42. To ensure a firm connection between the terminals and the busbar 422, laser welding is generally used to weld the battery cell 421 terminals and the busbar 422 together.

[0062] It should be noted that welding of terminals and busbars will generate fumes and welding slag. Although there is a dust extraction device in the battery module welding station, a small amount of fumes and welding slag will still be adsorbed onto the surface of the busbar. Therefore, the device of this utility model is required to perform post-weld cleaning treatment on the surface of the busbar.

[0063] To better understand the technical solution of this utility model, the working principle of this utility model is explained below.

[0064] First, the battery module tray assembly 4 is transported from right to left by the line assembly 3, so that the battery module tray assembly 4 moves from right to left to the post-welding cleaning station of the battery module (i.e., below the cleaning and dust removal mechanism 21 of the cleaning assembly 2). Then, under the action of the blocking cylinder 32, the battery module tray assembly 4 stops moving and the lifting plate 33 is controlled to lift upward, so that the battery module tray assembly 4 is separated from the line 31. At the same time, the lifting positioning pin 34 is inserted into the positioning bushing 415 in the battery module tray assembly 4, so that the battery module tray assembly 4 is accurately positioned. Then, the cleaning and dust removal mechanism 21 is driven to make linear movements in the front-back, left-right and / or up-down directions through the three-axis motion platform 22, so that the brush roller 216 in the cleaning and dust removal mechanism 21 contacts the busbar surface of the top (e.g., the leftmost position) of the battery module in the battery module tray assembly 4, that is, it reaches the working position (for example, in one embodiment, the working mode can be: if the battery module is in front of and below the cleaning and dust removal 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 removal mechanism 21 to the working position of the brush roller 216). Then, the stepper motor 211 drives the brush roller 216 to rotate. Under the action of the rotation of the brush roller 216, the smoke and welding slag are separated from the busbar 422. Then, under the action of the dust hood 217 and the dust collector, the separated smoke and welding slag are sucked into the dust collector located outside. Then, the Y-axis motion module 222 moves to the right with the cleaning and dust removal mechanism 21, cleaning the smoke and welding slag on each busbar 422 in turn. When the smoke and welding slag on all busbars 422 are cleaned, the lifting plate 33 ends the lifting, the battery module tray assembly 4 falls back onto the line 31, the blocking cylinder 32 releases, and the battery module tray assembly 4 flows to the next station.

[0065] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
