[0002] Lithium-ion batteries, like lead-acid batteries, are chemical power sources, and are mainly composed of positive electrode materials, negative electrode materials, diaphragms, electrolytes, and shells. The electrolyte is injected through the injection hole reserved in the shell, and a certain amount of residual liquid will remain around the injection hole. Since the electrolyte is a corrosive substance, if the residual liquid remaining in the injection hole is not cleaned, it will reduce the adhesion of the glue, damage the health of personnel, and corrode the shell. Therefore, the battery production process also involves cleaning it and drying the cleaned batteries for packaging. With the continuous advancement of technology, battery products are developing in the direction of high integration and diversification, which makes the positioning accuracy, cleaning effect, and cleaning efficiency of the battery cleaning increasingly higher.

[0003] Therefore, there is an urgent need for a lithium battery cleaning device with a simple structure, high positioning accuracy, good cleaning effect and high efficiency to meet the needs of automated production. Summary of the invention

[0028] In order to explain the technical content and structural features of the present invention in detail, further description will be given below in combination with the implementation modes and the accompanying drawings.

[0029] See also Figures 1 to 3The present invention provides a lithium battery cleaning device 100, which is suitable for conveying and positioning a battery 200, and cleaning and drying the conveyed battery 200. In the present application, the battery 200 is specifically a lithium battery. The lithium battery cleaning device 100 of the present invention mainly cleans the outer wall and the edge of the battery 200, and in particular can simultaneously complete the cleaning of the two long sides or the two short sides of the battery 200. Specifically, the lithium battery cleaning equipment 100 provided in the preferred embodiment of the present invention includes a conveying device 10, a loading device 20 arranged on the conveying device 10 in sequence along the conveying direction of the conveying device 10, a first cleaning device 30, a reversing device 40, a second cleaning device 50, a first drying device 60, a second drying device 70 and a unloading device 80. The conveying device 10 circulates a plurality of carriers 12 uniformly distributed on the chain conveying mechanism 11 through a chain conveying mechanism 11. The loading device 20 is used to drive the conveying carrier 12 to move so as to place the battery 200 to be cleaned on the carrier 12. At this time, the battery 200 is specifically placed horizontally on the carrier 12, and its long side is at a position opposite to the first cleaning device 30. The first cleaning device 30 is used to circulate the conveying carrier 12. The two long sides of the battery 200 on the carrier 12 are cleaned, and the reversing device 40 is used to rotate the battery 200 whose long sides have been cleaned by 90° and put it back on the carrier 12, so that the battery 200 is specifically placed on the carrier 12 horizontally and longitudinally, that is, its short side is in a position opposite to the second cleaning device 50, so that the second cleaning device 50 cleans the two short sides of the battery 200 whose long sides have been cleaned on the carrier 12 passed through, the first drying device 60 uses cold air to dry the cleaned battery 200 once, and the second drying device 70 uses hot air to dry the battery 200 after the primary drying. The unloading device 80 is used to drive the carrier 12 passed through to move, so as to remove the battery 200 after the secondary drying from the carrier 12, thereby completing the entire cleaning operation. Of course, in other embodiments, the two short sides of the battery 200 can also be cleaned first, and then the two long sides can be cleaned, and it is only necessary to adjust the front and rear positions of the first cleaning device 30 and the second cleaning device 50 accordingly.

[0030] In addition, the lithium battery cleaning equipment 100 of the present invention also includes two liquid supply systems 90, which are arranged in sequence on the lower side of the conveying device 10, and are connected to the first cleaning device 30 and the second cleaning device 50 in a one-to-one correspondence, for the transportation and recovery of the cleaning liquid. Specifically, in this embodiment, the number of the first cleaning device 30 and the second cleaning device 50 is two, respectively, and the two first cleaning devices 30 and the two second cleaning devices 50 are arranged in sequence along the conveying direction of the conveying device 10, so that with the conveying of the conveying device 10, the two long sides and the two short sides of the battery 200 are continuously cleaned twice, thereby effectively ensuring the cleaning effect and better adapting to the requirements of efficient transmission of the automated production line. Among them, in order to simplify the structure, the two first cleaning devices 30 can share one liquid supply system 90, and the two second cleaning devices 50 can share another liquid supply system 90. It should be noted that the lithium battery cleaning equipment 100 of the present invention also includes a controller, which is electrically connected to the conveying device 10, the loading device 20, the first cleaning device 30, the reversing device 40, the second cleaning device 50, the first drying device 60, the second drying device 70, the unloading device 80 and the liquid supply system 90, and is used to control the coordinated actions among the nine. Among them, the structure and working principle of the controller are well known in the art and will not be repeated here.

[0031] The following combination Figures 1 to 6 , the specific structure and working principle of the conveying device 10 are described:

[0032] See first Figures 1 to 4The conveying device 10 further includes a left frame 13 and a right frame 14 which are arranged in parallel and spaced apart along the Y-axis direction. The chain conveying mechanism 11 includes two gear assemblies, two ring chains 112 and at least one driving motor 113, wherein the two gear assemblies are symmetrically mounted on the left frame 13 and the right frame 14, the two ring chains 112 are connected to the two gear assemblies in a one-to-one correspondence, and a plurality of carriers 12 are mounted on the two ring chains 112 at equal intervals. The driving motor 113 is connected to the two gear assemblies to drive the two gear assemblies to rotate, so that the two ring chains 112 rotate accordingly, thereby cyclically transmitting each carrier 12 on the two ring chains 112. Preferably, the spacing between the left frame 13 and the right frame 14 is adjustable to accommodate the loading and transmission of carriers 12 of different sizes. Specifically, in this embodiment, each gear assembly includes a driving gear 114 and a driven gear 115 arranged in a straight line along the X-axis direction. The driving gear 114 and the driven gear 115 are rotatably arranged at the front and rear ends of the left frame 13 or the right frame 14. The ring chain 112 is meshed and connected to the driving gear 114 and the driven gear 115. The driving gear 114 is connected to the output end of the driving motor 113, so that it rotates under the drive of the driving motor 113, thereby driving the driven gear 115 and the ring chain 112 to rotate, so as to realize the cyclic transmission of the carrier 12. Specifically, a plurality of mounting plates 1121 arranged at equal intervals are correspondingly provided at the edges of the opposite side ends of the two ring chains 112, and two mounting grooves 12a arranged symmetrically are correspondingly provided at the left and right edges of the bottom side end of the carrier 12 (see Figure 5 ), the shape of the mounting groove 12a corresponds to the shape of the outer contour of the mounting piece 1121, when the mounting pieces 1121 on both sides of the carrier 12 are plugged into the corresponding mounting grooves 12a one by one, the carrier 12 can be conveniently and quickly fastened to the mounting pieces 1121 on both sides by screws, thereby realizing the assembly of the carrier 12 and the two ring chains 112. More specifically:

[0033] See also Figure 3 and Figure 4 Specifically, in this embodiment, the number of the driving motor 113 is one, and the driving motor 113 is specifically installed on the right side frame 14, and its output shaft 116 is rotatably inserted into the relative front side ends of the right side frame 14 and the left side frame 13, and the two driving gears 114 in the two gear assemblies are symmetrically inserted into the output shaft 116 between the left side frame 13 and the right side frame 14, and a rotating shaft 117 is rotatably inserted into the relative rear side ends of the right side frame 14 and the left side frame 13, and the two driven gears 115 are symmetrically inserted into the rotating shaft 117 between the left side frame 13 and the right side frame 14, so that the two driving gears 114 are driven to rotate synchronously by the driving motor 113, thereby driving the two ring chains 112 and the two driven gears 115 to rotate, so as to realize the cyclic transmission of the carrier 12, and the structure is simple and efficient, and the manufacturing cost is correspondingly reduced.

[0034] See also Figure 5 and Figure 6 Specifically, in this embodiment, the carrier 12 includes a mounting seat 121, a plurality of positioning posts 122 protruding at the relative center of the top side end of the mounting seat 121, a first clamping block 123 and a second clamping block 124 mounted on the mounting seat 121 and located at the front and rear opposite sides of the plurality of positioning posts 122, the plurality of positioning posts 122 are arranged at the same height and spaced apart, and are used to support the battery 200, and at least one of the first clamping block 123 and the second clamping block 124 is movably mounted on the mounting seat 121, so that it can cooperate with the other to clamp or release the battery 200 supported on the plurality of positioning posts 122. Since the plurality of positioning posts 122 are arranged at the same height and spaced apart, not only a horizontal supporting surface can be formed to facilitate the supporting of the battery 200, but also the spaced multi-point supporting facilitates the cleaning operation of the battery 200, and the cleaning brush can pass through the gap between the plurality of positioning posts 122 to more thoroughly clean the battery 200, and the drying operation after cleaning is also convenient. Furthermore, since at least one of the first clamping block 123 and the second clamping block 124 is movably arranged, the first clamping block 123 and the second clamping block 124 can not only realize the clamping and positioning of the battery 200, but also can be suitable for clamping and fixing the battery 200 in different placement directions by adjusting the spacing between the two, such as clamping and fixing the same battery 200 in different placement directions of horizontal horizontal placement or horizontal vertical placement on the supporting surface formed by multiple positioning columns 122, and can also adapt to the clamping and fixing of batteries 200 of different sizes, thereby effectively improving the compatibility of the carrier 12. The carrier 12 of the present invention has a simple overall structure, and by supporting and clamping the battery 200, the positioning is accurate and stable, easy to operate and highly adaptable, and more suitable for the needs of automated production. Preferably, the positioning column 122 is arranged on the mounting seat 121 in a height-adjustable manner, thereby further improving the adaptability of the carrier 12.

[0035] Specifically, in this embodiment, the number of the positioning posts 122 is four, and the four positioning posts 122 are arranged symmetrically in pairs, so that the battery 200 can be stably supported. The number of the first clamping block 123 and the second clamping block 124 are both two, and the two first clamping blocks 123 are arranged parallel to and spaced apart from each other along the Y-axis direction at the opposite front side ends of the mounting seat 121, and the two second clamping blocks 124 are arranged parallel to and spaced apart from each other along the Y-axis direction at the opposite rear side ends of the mounting seat 121. The arrangement of the two first clamping blocks 123 and the two second clamping blocks 124 can not only improve the stability of the positioning of the battery 200 through multi-point clamping, but also further provide an avoidance space, which is convenient for cleaning the battery 200 and drying it after cleaning. In addition, a card slot 12b is provided on the opposite sides of the first clamp block 123 and the second clamp block 124, which is used to clamp with the front and rear opposite sides of the top side end of the battery 200, thereby not only further improving the adaptability of the carrier 12, but also, through the clamping with the relative top side end of the battery 200, it can also effectively prevent the battery 200 from moving up and down in the vertical direction, thereby further improving the positioning accuracy.

[0036] Continue reading Figure 5 and Figure 6The carrier 12 further includes a guide rod 125 disposed at the opposite outer end of the mounting seat 121, a guide block 126 slidably inserted on the guide rod 125, and an elastic member 127 connected between the guide block 126 and the mounting seat 121. The guide rod 125 is horizontally arranged along the lateral width direction of the mounting seat 121. The top side end of the guide block 126 is used to connect with the second clamping block 124, so that the second clamping block 124 can be driven to move linearly close to or away from the first clamping block 123 by sliding the guide block 126 on the guide rod 125, so as to clamp or release the battery 200 supported on the positioning column 122. The elastic member 127 is used to constantly drive the guide block 126 to drive the second clamping block 124 to move linearly in the direction close to the first clamping block 123. Among them, the elastic member 127 is a spring. There are two guide rods 125, and the two guide rods 125 are arranged in parallel up and down with a certain distance. The guide block 126 is inserted on the two guide rods 125 to achieve smooth sliding. Furthermore, the ends of the two guide rods 125 are also connected with a connecting plate 128, which can not only strengthen the stability of the two guide rods 125, so that the guide block 126 can slide more smoothly, but also effectively prevent the guide block 126 from sliding out of the guide rod 125, thus playing a limiting role. Specifically, in this embodiment, the guide block 126 is provided with a plug-in slot 12c, and the output ends of the loading device 20 and the unloading device 80 can be correspondingly inserted into the plug-in slot 12c, so as to drive the guide block 126 to slide on the guide rod 125, thereby driving the second clamping block 124 to approach or move away from the first clamping block 123. Of course, in other embodiments, a protrusion can also be provided on the guide block 126, and the output ends of the loading device 20 and the unloading device 80 can push the protrusion, and can also drive the guide block 126 to slide on the guide rod 125.

[0037] Combination Figures 1 to 4 , Figure 7 and Figure 8 The structure and working principle of the loading device 20 and the unloading device 80 of the present invention are basically the same, the difference is that the actions to be completed are different, the former is used to place and fix the battery 200 on the carrier 12, and the latter is used to remove and unload the battery 200 on the carrier 12. The design of the same structure can effectively simplify the structure, facilitate assembly, and correspondingly reduce the manufacturing cost. The following takes the loading device 20 as an example to explain the specific structure and working principle of the loading device 20 and the unloading device 80:

[0038] See first Figures 1 to 4In general, the loading device 20 includes a positioning mechanism 21 and an opening and closing mechanism 22 arranged on the left and right opposite sides of the conveying device 10. The positioning mechanism 21 is used to abut against the lower side ends of the carrier 12 to position the carrier 12. The opening and closing mechanism 22 is used to drive at least one of the first clamping block 123 and the second clamping block 123 of the positioned carrier 12 to move linearly toward or away from the other, so as to cooperate with the other to clamp or release the battery 200 supported on the plurality of positioning columns 122. Among them, the positioning mechanism 21 can simultaneously position the plurality of carriers 12 conveyed on the chain conveying mechanism 11 each time, and the opening and closing mechanism 22 can drive the plurality of positioned carriers 12 to open and close at the same time each time, thereby effectively improving the efficiency of positioning and opening and closing. Specifically, the loading device 20 can simultaneously perform corresponding positioning and opening and closing operations on four carriers 12 each time.

[0039] Combination Figure 5 and Figure 7 Specifically, the positioning mechanism 21 includes a positioning seat 211 mounted on the right side frame 14, a Z-axis driver 212, a driving arm 213 and a pressing plate 214 mounted on the positioning seat 211, and the pressing plate 214 includes a pivoting portion 2141 and abutting portion 2142 located at both ends thereof, the pivoting portion 2141 is used to pivot with the front end relative to the positioning seat 211, and the abutting portion 2142 is suspended on the upper side of the chain transmission mechanism 11, and is used to abut with the carrier 12. The driving arm 213 includes a pivoting portion 2131 and a pressing portion 2132 located at both ends thereof, the pivoting portion 2131 is used to pivot with the rear end relative to the positioning seat 211, and the pressing portion 2132 is used to connect with the pressing plate 214, and the output end of the Z-axis driver 3212 is connected to the driving arm 213. The Z-axis driver 3212 is used to drive the driving arm 213 to rotate relative to the positioning seat 211, and the rotating driving arm 213 drives the pressing plate 214 to rotate relative to the positioning seat 211, so that the pressing plate 214 rotates to be close to or away from the carrier 12 on the chain transmission mechanism 11, so as to press and fix the carrier 12 or release the pressing and fixing of the carrier 12. Specifically, there are two driving arms 213 and two pressing plates 214, and the two driving arms 213 are symmetrically connected to the output end of the Z-axis driver 3212. The two pressing plates 214 are connected to the two driving arms 213 in a one-to-one correspondence, and each pressing plate 214 is used to press and position two carriers 12 at the same time, thereby effectively improving the efficiency and stability of the pressing and positioning, and the positioning effect is better.

[0040] Combination Figure 5 and Figure 8The opening and closing mechanism 22 includes an X-axis driver 221 installed on the left side frame 13, a Y-axis driver 222 connected to the output end of the X-axis driver 221, and a driving rod 223 connected to the output end of the Y-axis driver 222. The Y-axis driver 222 is used to drive the driving rod 223 to move linearly along the Y-axis direction, so that the driving rod 223 moves close to or away from the positioned carrier 12, thereby being inserted into the insertion slot 12c of the guide block 126 or withdrawn from the insertion slot 12c. The X-axis driver 221 is used to drive the driving rod 223 inserted in the insertion slot 12c to move linearly along the X-axis direction, thereby driving the guide block 126 to slide on the guide rod 125, and then driving the second clamping block 124 to make a linear movement away from or close to the first clamping block 123, so as to take and place the battery 200. Specifically, in this embodiment, the number of driving rods 223 is four, and the four driving rods 223 are driven by the X-axis driver 221 to move synchronously, thereby driving the corresponding four carriers 12 to open or close at the same time, so as to release or restore the clamping and fixing of the battery 200. The number of Y-axis drivers 222 can be two, and the two Y-axis drivers 222 are symmetrically connected to the output end of the X-axis driver 221, and the output end of each Y-axis driver 222 is symmetrically connected to two driving rods 223, so that the driving rod 223 can be driven to move more accurately. Of course, in other embodiments, the number of Y-axis drivers 222 can also be one, and one Y-axis driver 222 drives four driving rods 223 to move at the same time, thereby simplifying the structure.

[0041] See also Figure 8 In some optional embodiments, the opening and closing mechanism 22 further includes a Y-axis driver 224 connected to the output end of the X-axis driver 221 and an adjustment plate 225 connected to the output end of the Y-axis driver 224. The Y-axis driver 224 is used to drive the adjustment plate 225 to move linearly along the Y-axis direction to approach or move away from the battery 200 placed on the carrier 12, thereby fine-tuning the placement position of the battery 200 on the carrier 12 along the Y-axis direction. In specific use, when the carrier 12 is in the open position where the second clamping block 124 is relatively far away from the first clamping block 123, after the battery 200 is aligned and placed on the positioning column 122, the adjustment plate 225 is first used to adjust the alignment, and the carrier 12 is then restored to the closed position where the second clamping block 124 is relatively close to the first clamping block 123, thereby clamping the battery 200 supported on the positioning column 122, effectively improving the accuracy of subsequent cleaning, reversing and drying operations.

[0042] Combination Figure 1 , Figure 2 , Figures 9 to 11The structure and working principle of the first cleaning device 30 and the second cleaning device 50 of the present invention are basically the same. The former is used to clean the two long sides of the battery 200, and the latter is used to clean the two short sides of the battery 200. The design of the same structure can effectively simplify the structure, facilitate assembly, and correspondingly reduce the manufacturing cost. The following takes the first cleaning device 30 as an example to illustrate the structure and working principle of the first cleaning device 30 and the second cleaning device 50:

[0043] See also Figures 9 to 11 The first cleaning device 30 includes a brushing and transferring mechanism 32, two spraying mechanisms 33 and two brushing mechanisms 34 installed on the frame 31. The two spraying mechanisms 33 are arranged in parallel and spaced apart along the Y-axis direction and are located on the upper side of the conveying device 10. The spacing between the two spraying mechanisms 33 corresponds to the length or width of the battery 200. In the present device, it corresponds to the length of the battery 200, so that it is located above the two opposite long sides of the battery 200 being conveyed. The two brushing mechanisms 34 are respectively connected to the brushing and transferring mechanism 32 and are symmetrically arranged on the outer sides of the two spraying mechanisms 33. Each brush The washing mechanism 34 has a plurality of cleaning brushes 341 arranged in a straight line along the X-axis direction, and the cleaning brushes 341 are rotatably arranged relative to the frame 31. Each liquid spraying mechanism 33 has a liquid spraying port 331 arranged in a one-to-one correspondence with the cleaning brush 341 of the adjacent washing mechanism 34. The liquid spraying mechanism 33 is used to spray the cleaning liquid onto the battery 200 from each liquid spraying port 331. The washing transfer mechanism 32 is used to drive the two washing mechanisms 34 to move in a straight line along the X-axis direction and the Z-axis direction. The two rows of cleaning brushes 341 of the two moving washing mechanisms 34 are rotatably used to wash the two opposite long sides of the battery 200 sprayed with the cleaning liquid. It should be noted that when the battery 200 is single and relatively large in size, the two rows of liquid spray ports 331 are used to spray liquid at multiple points on the two opposite sides of the battery 200, and the two rows of cleaning brushes 341 are used to perform multi-point continuous cleaning, thereby achieving efficient and high-quality cleaning. When there are multiple batteries 200, the liquid spray ports 331 on both sides can be arranged in a one-to-one correspondence with the batteries 200, and the cleaning brushes 341 pass through the multiple batteries 200 in sequence, thereby achieving multiple cleaning of the multiple batteries 200. Specifically, in this embodiment, each liquid spray mechanism 33 has four liquid spray ports 331, and each brushing mechanism 34 has four cleaning brushes 341 arranged in a row, so that the cleaning operation of four batteries 200 can be achieved each time, effectively improving the cleaning efficiency, and the four cleaning brushes 341 are moved from the first of the four batteries 200 to the fourth in sequence to perform brushing, thereby performing multiple cleaning on each battery 200, effectively improving the cleaning effect.

The middle slide plate 313 is slidably mounted on the lower support plate 314 along the X-axis direction, specifically, on two linear guide rails 3141 of the lower support plate 314. Among them, the upper fixed plate 312, the middle slide plate 313, the lower support plate 314 and the bottom support plate 315 are provided with corresponding through grooves 312a, 313a, 314a and 315a at the relative centers thereof, and the corresponding through grooves 312a, 313a, 314a and 315a are interconnected along the Z-axis direction, so as to facilitate the placement of the two brushing mechanisms 34.

The two liquid spraying mechanisms 33 are detachably connected to the bottom support plate 315, and the two rows of liquid spraying ports 331 of the two are located above the two opposite sides of the battery 200. The spacing between each liquid spraying port 331 and the battery 200 is adjustable. The Z-axis driver 321 is used to drive the lower support plate 314 to move linearly along the Z-axis direction, thereby driving the middle slide plate 313 and the two brushing mechanisms 34 on the middle slide plate 313 to move linearly along the Z-axis direction to approach the battery to be cleaned. The X-axis driver 322 is used to drive the middle slide plate 313 to move linearly along the X-axis direction on the lower support plate 314, thereby driving the two brushing mechanisms 34 on the middle slide plate 313 to clean the two long side walls or the two short side walls of the battery. Among them, two connecting rods 3142 are also provided on the lower support plate 314, and the relative lower ends of the two connecting rods 3142 are symmetrically connected to the edges of the two opposite sides of the lower support plate 314 along the Y-axis direction, and the relative upper ends of the two connecting rods 3142 pass upward through the upper fixed plate 312 and are connected through a connecting plate 3143. The output end of the Z-axis driver 321 is connected to the center of the connecting plate 3143. The Z-axis driver 321 can specifically use a rotating motor, and realize the connection with the connecting plate 3143 through a screw rod connected thereto, so as to conveniently and smoothly drive the lower support plate 314 to move up and down, and the X-axis driver 322 can specifically use a linear motor.

[0046] See also Fig. 9 and Fig.10In some optional embodiments, the brushing and transferring mechanism 32 is also used to drive the two brushing mechanisms 34 to move linearly along the Y-axis direction to adjust the spacing between the two brushing mechanisms 34, so as to adapt to the cleaning of batteries 200 of different specifications and sizes, and to achieve the cleaning of batteries 200 with different placement directions, effectively improving the adaptability of the entire cleaning device. Specifically, the two brushing mechanisms 34 are movably arranged on the middle slide 313 along the Y-axis direction, and the brushing and transferring mechanism 32 also includes two Y-axis drivers 323, which are arranged on the middle slide 313 and connected to the two brushing mechanisms 34 in a one-to-one correspondence, and are used to drive the two brushing mechanisms 34 to move linearly along the Y-axis direction to adjust the spacing between the two brushing mechanisms 34.

The rotating motor 343 and the adjacent rotating wheels 344 are connected by synchronous belts 345. Each rotating wheel 344 has two belt winding areas arranged up and down. Except for the rotating wheel 344 farthest from the rotating motor 343, which is wound with only one synchronous belt 345, the remaining rotating wheels 344 are wound with two synchronous belts 345, so that the rotating wheels 344 are driven by a rotating motor 343 to rotate synchronously, and then the cleaning brushes 341 corresponding to the rotating wheels 344 are driven to rotate synchronously. The structure is simple and efficient. It should be noted that, in other embodiments, even if the rotating motor 343 is omitted, only the cleaning brush 341 is rotatably arranged on the middle slide plate 313, when the two rows of cleaning brushes 341 move close to the battery 200 and no longer move, the cleaning brushes 341 passing by can also be driven to rotate through the relative movement of the battery 200, so that the cleaning brushes 341 can also be rotated to scrub the battery 200. Specifically, the cleaning brush 341 includes a brush rod 3411 and a brush head 3412, the upper end of the brush rod 3411 is used to connect with the rotating motor 343 of the scrubbing mechanism 34, and the lower end of the brush rod 3411 is detachably connected with the brush head 3412, so that the frequently used brush head 3412 can be replaced efficiently and quickly, and the corresponding brush head 3412 can also be selected according to the specific shape of the battery.

[0048] Combination Figure 1 , Figure 2 and Fig.12 The reversing device 40 includes a suction transfer mechanism 42, a steering mechanism 43, a plurality of vacuum suction nozzles 44 and a correction mechanism 45 installed on a frame 41. The steering mechanism 43 is connected to the output end of the suction transfer mechanism 42. The plurality of vacuum suction nozzles 44 are connected to the output end of the steering mechanism 43 at equal intervals. The correction mechanism 45 is installed on the conveying device 10. The suction transfer mechanism 43 is used to drive the plurality of vacuum suction nozzles 44 to move linearly along the Z-axis direction and the Y-axis direction. The moving vacuum suction nozzles 44 are used to suck the carrier. The battery 200 on the carrier 12 or the sucked battery 200 is placed back on the carrier 12, and during the picking and placing process, the steering mechanism 43 is used to drive the multiple vacuum nozzles 44 to rotate, and the rotating vacuum nozzles 44 are used to drive the sucked battery 200 to rotate a certain angle, and the correction mechanism 45 is used to make a linear movement along the Y-axis direction close to or away from the carrier 12, so as to abut against the battery 200 that is rotated and placed back on the carrier 12 from the outside of the carrier 12, thereby correcting the placement position of the battery 200.

[0049] Specifically, the suction and transfer mechanism 42 includes an X-axis driver 421, a Z-axis driver 422 connected to the output end of the X-axis driver 421, and a mounting frame 423 connected to the output end of the Z-axis driver 422.

The X-axis driver 421 and the Z-axis driver 422 drive the multiple vacuum nozzles 44 to move linearly along the X-axis direction and the Z-axis direction, respectively. The X-axis driver 431 is used to drive the rack 432 to move linearly along the X-axis direction, so that the multiple gears 433 rotate accordingly, thereby driving the multiple vacuum nozzles 44 correspondingly connected to the multiple gears 433 to rotate synchronously, so that the multiple batteries 200 sucked by the multiple vacuum nozzles 44 rotate synchronously. Among them, the X-axis driver 421 and the Z-axis driver 422 are specifically linear motors, and the X-axis driver 431 is specifically a linear cylinder.

[0050] See also Fig.12The correction mechanism 45 includes a mounting seat 451, a pressing plate 452 and a Z-axis driver 453 mounted on the bottom side of the mounting seat 451, and a correction plate 454 and a Y-axis driver 455 mounted on the top side of the mounting seat 451. The pressing plate 452 is rotatably mounted on the mounting seat 451 and connected to the output end of the Z-axis driver 453, so that it rotates relative to the mounting seat 451 under the drive of the Z-axis driver 453, and can be rotated to abut against the carrier 12 to fix the carrier 12 and prevent the carrier 12 from shaking during the process of taking and placing the battery 200, thereby improving the reversing positioning accuracy and efficiency. The correction plate 454 is movably arranged on the mounting seat 451 and connected to the output end of the Y-axis driver 455, so that it moves linearly along the Y-axis direction under the drive of the Y-axis driver 455 to abut against the battery 200 on the carrier 12 to check whether the battery 200 is properly placed on the carrier 12, and the correction plate 454 can be used to push the battery 200 to adjust the placement position of the battery 200. Specifically, the Z-axis driver 453 uses a linear cylinder, and the Y-axis driver 455 uses a linear motor. The correction plate 54 is in the shape of a strip, and the movement of a correction plate 54 can realize the synchronous verification of the corresponding batteries 200 carried on multiple carriers 300, thereby simplifying the structure and effectively improving the verification efficiency.

[0051] Specifically, in some optional embodiments, a correction plate 454 and a corresponding Y-axis driver 455 may be provided on opposite sides of the left frame 13 and the right frame 14 of the conveying device 10 , so that the placement position of the battery 200 can be corrected from two opposite sides of the carrier 12 . Of course, a Y-axis driver 456 and a plurality of push-pull blocks 457 may also be installed at the relative top side end of the mounting seat 451. The plurality of push-pull blocks 457 are connected to the output end of the Y-axis driver 456 at intervals, and are arranged one-to-one with the batteries 200 on each carrier 12. Each push-pull block 457 is movably inserted into the correction plate 454 along the Y-axis direction, and has a hook-pull portion at the end away from the correction plate 454. The Y-axis driver 456 is used to drive each push-pull block 457 to move relative to the correction plate 454, so that the hook-pull portion of each push-pull block 457 can drive the corresponding battery 200 on the carrier 12 to press against the correction plate 454 from the other side of the carrier 12, thereby realizing synchronous correction of the placement position of the batteries 200 on each carrier 12 from two opposite sides through the cooperation of a correction plate 454 and a plurality of push-pull blocks 457. The layout is reasonable, the structure is simple and the correction efficiency is high. Specifically, the Y-axis driver 456 uses a linear cylinder.

[0052] See also Figure 1 and Figure 2Specifically, in this embodiment, the first drying device 60 removes the cleaning liquid remaining on the surface of the battery 200 by means of an air knife, and the second drying device 70 removes the moisture on the surface of the battery 200 after the primary drying by means of a hot air blower, thereby completely drying the battery 200. It should be noted that, in some optional embodiments, a reversing device 40 may also be provided between the second cleaning device 50 and the first drying device 60. The reversing device 40 is specifically provided above the first drying device 60, and is used to rotate the battery 200 that has been passed through the first drying device 60 after the short side is cleaned by 90° and then put it back on the carrier 12, so that the cleaned battery 200 is placed horizontally on the carrier 12, and its long side is in a position opposite to the first drying device 60, so that the first drying device 60 and the subsequent second drying device 70 and the unloading device 80 perform primary drying, secondary drying and unloading operations on the battery 200 on the carrier 12 that has passed through.

[0053] See also Figures 1 to 12 , the working principle of the lithium battery cleaning device 100 of the present invention is described as follows:

[0054] First, the conveying device 10 cyclically conveys the carriers 12 in groups of four between the workstations. After conveying the four carriers 12 to the loading device 20, the positioning mechanism 21 and the opening and closing mechanism 22 of the loading device 20 are actuated to simultaneously press and position the four carriers 12 conveyed, and then the guide blocks 126 of the four positioned carriers 12 are driven to slide synchronously on the guide rods 125, so that each second clamping block 124 moves linearly away from the first clamping block 123 to make way, so that the four batteries 200 are placed one by one on the four carriers 12 by manual operation or a robot, and then the loading device 20 reverses and each second clamping block 124 is reset to clamp the batteries 200 placed on the carriers 12; thereafter, the conveying device 10 conveys the four carriers 12 carrying the batteries 200 toward the first cleaning device 30;

[0055] Next, when the four carriers 12 carrying the batteries 200 are transferred to the first first cleaning device 30, the first cleaning device 30 is activated. First, the Z-axis driver 321 of the brushing and transferring mechanism 32 drives the two rows of cleaning brushes 341 to move downward synchronously, so that the two rows of cleaning brushes 341 are close to the two long sides of the battery 200. The X-axis driver 322 of the brushing and transferring mechanism 32 is activated accordingly, driving the two rows of cleaning brushes 341 to move linearly along the X-axis direction. At the same time, the two liquid spraying mechanisms 30 and the two rotating motors 343 are activated, and the two liquid spraying mechanisms 30 spray the cleaning liquid from the corresponding liquid spraying ports 331 accurately onto the battery 200. 00, two rotating motors 343 drive the correspondingly connected cleaning brushes 341 to rotate, so that the two rows of moving cleaning brushes 341 are rotated to brush the two long sides of the battery 200 sprayed with the cleaning liquid, and move from the first carrier 12 of four to the fourth carrier 12 to complete one brushing of the two long sides of the four batteries 200 in a group, and then the conveying device 10 conveys the battery 200 after the long side is brushed once to the second first cleaning device 30, and repeats the above cleaning action to complete the second brushing of the two long sides of the four batteries 200 in a group;

[0056] Then, the reversing device 40 simultaneously removes the four batteries 200 whose long sides have been secondarily cleaned from the corresponding carriers 12, rotates them 90°, and then puts them back on the carriers 12, so that as the conveying device 10 continues to convey, the two second cleaning devices 50 successively perform second cleaning on the two short sides of the four batteries 200 conveyed; then, the first drying device 60 and the second drying device 70 successively perform cold air drying and hot air drying on the four batteries 200 that have been cleaned;

[0057] Finally, the conveying device 10 conveys the carriers 12 carrying the batteries 200 in groups of four after secondary drying to the unloading device 80, and the positioning mechanism 21 and the opening and closing mechanism 22 provided at the station cooperate to press and fix the four carriers 12 conveyed and drive the four fixed carriers 12 to open and close synchronously, thereby releasing the clamping and fixing of the batteries 200, so that the batteries 200 can be removed manually or by a robot.

[0058] By repeating the above actions continuously, the automated production line operation of conveying, positioning, cleaning and drying the battery 200 can be completed.

[0059] Compared with the prior art, in the lithium battery cleaning equipment 100 provided by the present invention, on the one hand, a plurality of carriers 12 uniformly distributed thereon are cyclically transmitted through the chain conveying mechanism 11, so that the carrier 12 is cyclically transmitted through the loading device 20, the first cleaning device 30, the reversing device 40, the second cleaning device 50, the first drying device 60, the second drying device 70 and the unloading device 80, and the transmission is stable and the positioning is accurate, and the simultaneous transmission and precise positioning of the carriers 12 of multiple processes and multiple stations can be realized, so as to efficiently complete the corresponding actions, and the carrier 12 is driven by the loading device 20 and the unloading device 80, so that the carrier 12 is in a position convenient for the placement and removal of the battery 200, thereby further improving the cleaning efficiency. In addition, during the cleaning process, the battery 200 is always positioned on the carrier 12 of the conveying device 10, and there is no need to move it. When the battery 200 is transferred to a cleaning tank or other cleaning mechanism, there is no need for secondary positioning, thereby optimizing the structure and further improving the positioning accuracy and cleaning efficiency. On the other hand, the first cleaning device 30 simultaneously cleans the two long sides of the battery 200, and the reversing device 40 automatically rotates the battery 200 90° after the long side cleaning is completed, thereby adjusting the placement direction of the battery 200 on the carrier 12, so that the second cleaning device 50 can simultaneously clean the two short sides of the battery 200, thereby effectively improving the cleaning efficiency and accurately transmitting and positioning. Moreover, the cleaned battery 200 is also secondary dried by the cold air of the first drying device 70 and the hot air of the second drying device 80, so that the drying effect is better. The lithium battery cleaning equipment 100 of the present invention has a simple overall structure, a reasonable layout, high transmission positioning accuracy, good cleaning effect and high efficiency.
