Description

Technical Field

[0001] The present application relates to the technical field of battery cleaning, and in particular to a cleaning device for batteries after acid addition. Background Art

[0002] In the process of preparing the battery, it is usually necessary to fill the battery shell with dilute sulfuric acid as an electrolyte. In the process of filling the dilute sulfuric acid electrolyte, the dilute sulfuric acid easily overflows from the top of the shell and overflows onto the side wall of the battery, so that a certain amount of dilute sulfuric acid residual liquid exists on the top and four side surfaces of the shell of the prepared battery. In order to ensure that the cleanliness of the battery surface meets the requirements, the electrolyte adhering to the top and four side surfaces of the battery needs to be cleaned.

[0003] The existing battery cleaning device after acid addition often cleans the battery by flushing the top and four side surfaces of the battery, and then dries the cleaned battery. Since this cleaning method will cause a lot of liquid cleaning solution to remain on the surface of the battery, it will cause the user to spend a lot of time to dry the battery, and there is a problem of low drying efficiency.

[0004] For example, a patent document with publication number CN114178233B discloses a battery cleaning machine and a battery cleaning method. In the technical solution of the patent document, the battery is cleaned by flushing the electrolyte remaining on the top and four side surfaces of the battery. However, the cleaning structure used will cause more cleaning liquid to remain on the surface of the battery. Therefore, after cleaning the battery, the user will need to spend a lot of time to complete the drying of the cleaned battery, which will affect the overall efficiency of the battery processing.

[0029] In summary, compared with the prior art, the present application includes at least one of the following beneficial technical effects:

[0030] 1. Without affecting the transportation of the battery, the flexible absorbent block and the scraper can be used to remove the cleaning liquid on the top and outer side of the battery, thereby improving the cleaning effect and increasing the drying rate of the battery. At the same time, the flexible absorbent block can be squeezed to drain water to maintain a good absorption effect.

[0031] 2. Since a downward force is applied to the battery during the process of absorbing and cleaning the residual cleaning liquid on the top of the battery and scraping and cleaning the residual cleaning liquid on the four side surfaces of the battery, if the bottom of the battery is brought into contact with the continuously running roller conveyor during this process, the bottom of the battery may be easily worn by the continuously running roller conveyor. However, the technical solution of the present application is to clean the residual cleaning liquid on the battery after lifting the battery from the roller conveyor, thereby effectively avoiding the wear of the bottom of the battery by the continuously running roller conveyor during the process of cleaning the residual cleaning liquid on the top and four side ends of the battery.

[0032] 3. Lifting the batteries that need to be cleaned off the roller conveyor can not only ensure the orderly movement of other batteries, but also more fully and thoroughly remove the residual liquid at the bottom of the battery, thereby achieving all-round removal of the residual cleaning liquid on the battery, thereby further improving the subsequent drying efficiency of the battery.

[0040] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme of the embodiments of the present application will be clearly and completely described below in combination with the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the described embodiments of the present application, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of this application.

[0041] Reference Figure 1The present embodiment provides a cleaning device for batteries after acid addition, comprising a frame 1, a roller conveyor 2, a spray box 3, a feed port, a discharge port, a lifting module, a movable frame 4, a fixed plate 5, a push plate 6, a translation drive module, a side plate 7, a support plate 8, a cross plate 9, an inclined surface 10, an inclined surface 2 11, a cleaning frame 12, a wiper assembly 18, a flexible water absorbing block 13, a water removal unit, a flap 14 and a baffle 15.

[0042] Reference Figure 1 , Figure 2 , Figure 4 and Figure 6 The roller conveyor 2 is arranged on the frame 1, the spray box 3 is arranged at the rear end of the frame 1, and the spray box 3 is located above the roller conveyor 2, the rear end of the spray box 3 is provided with a feed port, and the front end of the spray box 3 is provided with a discharge port, the lifting module is arranged on the frame 1, and the lifting module is located at the front side of the spray box 3, the movable frame 4 is arranged on the lifting module, the fixed plate 5 is fixedly connected to the lower end of the movable frame 4, the push plate 6 is horizontally slidably connected to the fixed plate 5, the side plate 7 is fixedly connected to the outer side of the push plate 6, and the support plate 8 is fixedly connected to the outer side of the side plate 7 away from the push plate 6. The transverse plate 9 is arranged between the left and right side ends of the frame 1, and the transverse plate 9 is arranged corresponding to the gap between adjacent rollers of the roller conveyor 2. The top of the transverse plate 9 is not higher than the upper surface of the vertical roller of the roller, so as to avoid obstruction to the transportation and lifting of the battery. The inclined surface 10 is arranged on both sides of the middle of the transverse plate 9, and the inclined surface 2 11 is arranged at the bottom end of the support plate 8. The inclined surface 10 is adapted to the inclined surface 2 11. When the support plate 8 moves inward, the inclined surface 10 will cooperate with the inclined surface 2 11, and the transverse plate 9 will lift the support plate 8 and the side plate 7 upward to lift the battery from the roller conveyor.

[0043] The cleaning frame 12 is arranged on the bottom wall in the middle of the top end of the movable frame 4, the wiper assembly 18 is arranged on the lower inner wall of the cleaning frame 12, the flexible water-absorbing block 13 is arranged on the top of the movable frame 4 and located on the inner side of the cleaning frame 12, and the flexible water-absorbing block 13 is a water-absorbing sponge block; the water removal unit is arranged on the movable frame 4, and is used to remove the cleaning liquid absorbed by the flexible water-absorbing block 13, the flap 14 is swingably arranged on the front side of the movable frame 4, and the baffle 15 is arranged on the rear side of the movable frame 4.

[0044] After a battery to be cleaned with residual cleaning fluid is conveyed to the bottom of the movable frame 4 by the roller conveyor 2, the battery will be positioned and adjusted in the front-to-back direction due to the obstruction of the flap 14, and the position of the battery in the front-to-back direction will be adapted to the cleaning frame 12. At the same time, the baffle 15 will block the next battery to prevent it from affecting the cleaning process of the residual cleaning fluid of the battery and the water absorption process of the flexible absorbent block 13.

[0045] Afterwards, the two push plates 6 can be driven by the translation drive module to move toward the middle, and the side plates 7 will also drive the support plate 8 to move during the process of moving toward each other. With the cooperation of the inclined surface 10 and the inclined surface 2 11, the cross plate 9 will lift the support plate 8 and the side plate 7 upward, thereby lifting the battery from the roller conveyor 2, and simultaneously adjust the position of the battery in the left and right directions so that the battery is located below the cleaning frame 12. Afterwards, the cleaning frame 12 is moved downward by the lifting module, and the cleaning fluid adhered to the four sides of the battery is scraped off by the wiper assembly 18, and the cleaning fluid remaining on the top of the battery is absorbed and cleaned by the flexible absorbent block 13.

[0046] During the battery cleaning process, in order to prevent the flap 14 from interfering with the vertical movement of the cleaning frame 12, the flap 14 can be rotated after the battery is lifted off the roller conveyor 2 and before cleaning, so that the flap 14 is misaligned with the cleaning frame 12.

[0047] In this embodiment, the cleaning frame 12 can only scrape away the residual cleaning liquid in most areas of the four side ends of the battery due to the interference of the side plate 7, while the flexible absorbent block 13 can absorb and clean the residual cleaning liquid on the top of the battery; the user only needs to appropriately lower the height of the side plate 7 and appropriately increase the thickness of the flexible absorbent block 13.

[0048] Afterwards, the movable frame 4, the cleaning frame 12 and the flexible water-absorbing block 13 can be moved upward by the lifting module for a certain distance, so that the cleaning frame 12 is higher than the top of the battery, and the battery is returned to the roller conveyor 2 by the translation drive module, so that the cleaned battery can continue to be conveyed forward; but because of the obstruction of the baffle 15, the next battery still cannot enter under the movable frame 4. At this time, the flexible water-absorbing block 13 can be dehydrated by the dehydration unit, so that the flexible water-absorbing block 13 can continue to effectively absorb the residual cleaning liquid on the top of the battery.

[0049] Afterwards, the movable frame 4 and the baffle 15 can continue to move upward for a certain distance and reset, so that the baffle 15 releases the limiting effect on the next battery, allowing the next battery to move to the bottom of the movable frame 4. After that, the cleaning liquid remaining on the top of the next battery can be sucked and cleaned, and the cleaning liquid remaining in most of the side end areas can be scraped and cleaned.

[0050] Reference Figure 2 The wiper assembly 18 is a scraper strip respectively arranged on the inner walls of the four side ends of the bottom of the cleaning frame 12.

[0051] When the cleaning frame 12 moves downward relative to the battery, the scraping strips on the inner walls of the four side ends of the bottom of the cleaning frame 12 will scrape and clean the cleaning liquid remaining on the four side ends of the battery.

[0052] In addition, the wiper assembly 18 can also be a wiper frame strip disposed on the inner side wall of the cleaning frame 12. When the cleaning frame 12 moves downward relative to the battery, the wiper frame strip disposed on the inner side wall of the cleaning frame 12 will scrape and clean the residual cleaning fluid on the four side ends of the battery, which will not be described in detail here.

[0053] Reference Figure 2 The water removal unit includes a first telescopic push rod 21, a mounting frame 22 and a water removal roller 23.

[0054] The first telescopic push rod 21 is arranged at one side end of the movable frame 4 in the left-right lateral direction, the mounting frame 22 is arranged at the end of the output shaft of the first telescopic push rod 21, the mounting frame 22 is U-shaped, and the dewatering roller 23 is rotatably arranged between the two side ends of the mounting frame 22, and the dewatering roller 23 is used for rolling and dewatering the flexible water-absorbing block 13.

[0055] When there is no battery under the movable frame 4, the output shaft of the first telescopic push rod 21 can be extended to a certain length, so that the dewatering roller 23 can be moved from the outside of the cleaning frame 12 to the other side of the flexible absorbent block 13, so that the cleaning liquid absorbed by the flexible absorbent block 13 is rolled and removed, and the cleaning liquid passes through the roller conveyor. Subsequently, the output shaft of the first telescopic push rod 21 can be shortened to a certain length, so that the dewatering roller 23 is reset to the outside of the cleaning frame 12, so that the flexible absorbent block 13 can continuously and effectively absorb and clean the cleaning liquid remaining on the top of the battery.

[0056] The bottom of the flexible water-absorbing block 13 is also provided with a water-absorbing projection that matches the groove on the top of the battery. Through the water-absorbing projection, the flexible water-absorbing block 13 can better contact the top of the battery, thereby more fully absorbing and cleaning the residual cleaning fluid on the top of the battery.

[0057] Reference Figure 4 A blow hood 16 for cleaning the residual cleaning liquid on the bottom surface of the battery is also provided at one side end of the frame 1 close to the cleaning frame 12. The blow hood 16 is also provided with an air duct 17, which passes through the side end of the frame 1 and extends to the outside of the frame 1.

[0058] In the process of cleaning the residual cleaning fluid on the top and side ends of the battery, the air duct 17 can be connected to an external blowing device, and the wind is transmitted to the blowing hood 16 through the air duct 17 and blown out, thereby blowing and cleaning the residual cleaning fluid on the bottom surface of the battery.

[0059] Reference Figure 1 The lifting module includes two second telescopic push rods 31, four guide rods 32 and two top plates 33. The two second telescopic push rods 31 are respectively vertically arranged at the left and right ends of the top of the frame 1, and the two ends of the movable frame 4 are respectively connected to the top of the output shaft of the second telescopic push rods 31 on both sides; the four guide rods 32 are respectively vertically arranged at the left and right ends of the top of the frame 1, and the four guide rods 32 are respectively vertically slidably connected to the four corners of the movable frame 4, and the two top plates 33 are respectively arranged on the top of the two guide rods 32 on the same side.

[0060] The movable frame 4 can be raised and lowered conveniently and flexibly by only extending or shortening the output shafts of the second telescopic push rods 31 on both sides synchronously by a certain length. During the raising and lowering adjustment process, the movable frame 4 will also drive the cleaning frame 12, the wiper assembly 18 and the flexible water-absorbing block 13 to be raised and lowered. During the raising and lowering adjustment process, the movable frame 4 can also slide vertically relative to the guide plug rod 32, so that the movable frame 4 can move vertically more smoothly and avoid deformation and damage of the second telescopic push rod 31 due to non-vertical forces.

[0061] Reference Figure 2 and Figure 3 The translation driving module includes two mounting plates 41 , two racks 42 , four support rods 43 , two transverse shafts 44 , a gear 1 45 , a gear 2 46 and a rack 2 47 .

[0062] The two mounting plates 41 are respectively arranged on the left and right side ends of the movable frame 4, and the two mounting plates 41 are both L-shaped. The two racks 42 are respectively arranged vertically on the vertical parts of the two mounting plates 41. Two support rods 43 are respectively arranged on the outer side of each fixed plate 5. The two horizontal shafts 44 rotate respectively between the two support rods 43 on the same side. The two gears 45 are respectively arranged on the two horizontal shafts 44, and the two gears 45 are respectively meshed with the corresponding racks 42. The two gears 46 are respectively arranged on the two horizontal shafts 44, and the diameter of the gear 46 is larger than the diameter of the gear 45. The rack 47 is meshed with the gear 46, and the two racks 47 are respectively arranged on the top of the two push plates 6.

[0063] When the movable frame 4 is lowered by the lifting module, the movable frame 4 will drive the mounting plates 41 and rack 1 42 on both sides to move downward, the rack 1 42 will drive the gear 1 45 to rotate, and the gear 1 45 will drive the gear 2 46 to rotate during the rotation, and the gear 2 46 will drive the rack 2 47 to slide inward during the rotation, and the two racks 2 47 will respectively drive the corresponding push plates 6 to slide left and right relative to the fixed plate 5, and the push plates 6 will drive the side plates 7 to move towards each other in the direction close to the battery, so that the two side plates 7 are close to each other.

[0064] On the contrary, when the lifting module is used to adjust the movable frame 4 to rise, the movable frame 4 will cooperate with the mounting plate 41, rack 1 42, gear 1 45 and gear 2 46 to move rack 2 47 and push plate 6 outward, thereby moving the side plate 7 away from the battery.

[0065] In this embodiment, the translation drive module is driven by the lifting module and operates in coordination with the lifting module; however, in other embodiments, the translation drive module can also be an automatic telescopic rod arranged on the fixed plate 5, and the end of the output shaft of the automatic telescopic rod is connected to the push plate 6 through a connecting plate. In this way, it is only necessary to independently adjust the telescopic rod according to the operating state of the lifting module, and the translation drive of the push plate 6 can also be realized, which will not be repeated here.

[0066] Reference Figure 3 The rear ends of the two side plates 7 are also provided with guide plates 67 tilted outwards. The two guide plates 67 together form an outer eight-shaped guide channel, thereby making it easy for the storage battery to enter between the two side plates 7.

The fixed slide groove 57 is arranged at the top of the fixed frame 53, and the fixed slide groove 57 is slidably connected with the rack three 54. The third telescopic push rod 56 is arranged at the front side end of the top of the fixed frame 53, and the end of the output shaft of the third telescopic push rod 56 is connected to the front side end of the rack three 54.

[0068] It is only necessary to extend the output shaft of the third telescopic push rod 56 by a certain length so that the rack three 54 can slide relative to the fixed frame 53 in the opposite direction of the conveying direction, and the rack three 54 will drive the gear three 55 to rotate, and the gear three 55 will drive the flap 14 to swing and adjust in the opposite direction of the conveying direction to a state of vertical translation with the cleaning frame 12, thereby limiting the front and rear directions of the battery; it is only necessary to shorten the output shaft of the third telescopic push rod 56 by a certain length so that the rack three 54 can slide relative to the fixed frame 53 along the conveying direction, and the rack three 54 will drive the gear three 55 to rotate, and the gear three 55 will drive the flap 14 to swing and adjust in the conveying direction to a state higher than the height of the battery, so that the battery returned to the roller conveyor can continue to be conveyed.

[0069] Reference Figure 3 , Figure 4 and Figure 5 , and also includes an anti-interference module 1 and an anti-interference module 2. The anti-interference module 1 includes an extension plate 61, a groove 1 62, a partition 1 63 and a clearance hole 64. The extension plate 61 is arranged on the top of the side plate 7, the groove 1 62 is opened on the inner side wall of the extension plate 61, the partition 1 63 is flipped and connected with the groove 1 62 through a torsion spring, and the partition 1 63 can flip downward into the inside of the groove 1 62 when subjected to a downward force, and the partition 1 63 can flip out of the groove 1 62 under the cooperation of the torsion spring when subjected to an upward force; the clearance hole 64 is arranged on the support plate 8, and the clearance hole 64 is adapted to the cleaning frame 12.

[0070] Reference Figure 3 , Figure 4 and Figure 5 The anti-interference module 2 includes a groove 2 65 and a partition 2 66. The groove 2 65 is opened on the inner wall of the flap 14. The partition 2 66 is flipped and connected to the groove 2 65 through a torsion spring. When the partition 2 66 is subjected to a downward force, it can flip downward into the interior of the groove 2 65. When the partition 2 66 is subjected to an upward force, it can flip out of the groove 2 65 with the cooperation of the torsion spring.

[0071] When the battery is lifted and positioned in the left and right directions, the partition 63 can be made to collide with the side ends of the battery, so that there is a gap between the side plate 7 and the left and right side ends of the battery, thereby avoiding interference between the cleaning frame 12 and the side plate 7 during the downward movement of the battery. When the cleaning frame 12 touches the partition 63, the flap 14 can be flipped into the groove 62 through the torsion spring, thereby avoiding obstruction to the subsequent vertical movement of the cleaning frame 12, so that the cleaning frame 12 can be inserted into the support plate 8 through the clearance hole 64, so that the wiper assembly 18 moves to the bottom of the battery, thereby fully scraping and cleaning the cleaning fluid on the four side ends of the battery; when the cleaning frame 12 moves upward to the top of the partition 63, the partition 63 will be flipped to a horizontal state again under the action of the torsion spring for reset.

[0072] Partition 2 66 can create a gap between the flap 14 and the front side end of the battery, thereby avoiding interference between the flap 14 and the cleaning frame 12 during the downward movement relative to the battery. When the cleaning frame 12 touches partition 2 66, the flap 14 can be flipped into groove 2 65 through the torsion spring, thereby avoiding obstruction to the subsequent vertical movement of the cleaning frame 12. When the cleaning frame 12 moves upward to above partition 2 66, it can be flipped again to a horizontal state and reset under the action of the torsion spring. Therefore, when the user is cleaning the residual cleaning fluid on the battery, there is no need to flip the flap 14 before moving the cleaning frame 12 downward. The user can wait until the residual cleaning fluid in the battery is cleaned before flipping the flap 14, thereby effectively preventing the battery from easily shifting in the front-to-back direction during the cleaning process.

[0073] Reference Figure 2 and Figure 3 The translation driving module also includes two support plates 48, two support slots 49, a through hole, two connecting plates 410, an auxiliary support slot 411, an auxiliary support rod 412, a connecting slider and a connecting slot 413.

[0074] Reference Figure 2 and Figure 3, the two support plates 48 are both arranged on the top of the frame 1, and the two support plates 48 are respectively located on the inner sides of the corresponding fixed plates 5, the two support slide grooves 49 are arranged between the corresponding fixed plates 5 and the support plates 48, the two push plates 6 are respectively slidably connected with the two support slide grooves 49, and the through holes are arranged on the support plates 48 and the fixed plates 5 on both sides, and the through holes are adapted to the corresponding racks 47 and the support slide grooves 49; the outer ends of the two connecting plates 410 are respectively connected with the inner ends of the two push plates 6, and the inner ends of the two connecting plates 410 are respectively connected with the inner ends of the two push plates 6. The side ends are respectively connected to the corresponding side plates 7 in vertical sliding manner, the auxiliary support groove 411 is arranged between the support plates 48 and the fixed plate 5 on both sides, the auxiliary support rod 412 is Z-shaped, the upper horizontal part of the auxiliary support rod 412 is connected to the auxiliary support groove 411 in sliding manner, and the inner side end of the auxiliary support rod 412 is connected to the side plate 7 in vertical sliding manner; the inner side ends of the connecting plates 410 and the auxiliary support rod 412 on both sides are respectively provided with connecting sliders, and the outer side wall of the side plate 7 is provided with connecting grooves 413 connected to the corresponding connecting sliders in sliding manner. Both the connecting slider and the connecting groove 413 are dovetail-shaped, and in another embodiment, the connecting slider and the connecting groove 413 can also be T-shaped, so that the connecting slider can only slide vertically relative to the connecting groove 413 and cannot be relatively offset horizontally.

[0075] When the rack 2 47 applies a force to the push plate 6, the push plate 6 will slide relative to the supporting groove 49, and the push plate 6 will move the side plate 7 through the connecting plate 410, the connecting slider and the connecting groove 413; under the support of the supporting groove 49, when the side plate 7 is driven to translate left and right through the connecting plate 410, the auxiliary support rod 412 can also slide left and right relative to the fixed plate 5 and the support plate 48, so that the side plate 7 can slide left and right smoothly; the cooperation between the inclined surface 10 and the inclined surface 2 11 makes it possible for the side plate 7 to slide vertically relative to the auxiliary support plate 48 during the vertical movement of the side plate 7 relative to the connecting plate 410 and the rack 2 47, so that the vertical movement of the side plate 7 is smoother.

[0076] Reference Figure 4 The bottom of the frame 1 is also provided with a liquid collecting tank 71 covered under the roller conveyor 2, and the bottom of the liquid collecting tank 71 is provided with a liquid outlet pipe 72, which is arranged at the bottom of the middle end of the liquid collecting tank 71, and the left and right sides of the liquid collecting tank 71 are inclined toward the middle.

[0077] The cleaning liquid generated by flushing the battery filled with electrolyte, the cleaning liquid cleaned from the battery, and the cleaning liquid cleaned from the flexible absorbent block 13 will fall into the liquid collecting tank 71 to be collected and processed, and the collected cleaning liquid can be discharged from the collecting tank through the liquid outlet pipe 72.

[0078] The implementation principle of the embodiment of the present application is: multiple batteries filled with electrolyte are placed on the loading end of the roller conveyor 2 respectively, so that they enter the spray box 3 through the feed port, and the electrolyte remaining on the top and four side ends of the battery is washed off, and then removed from the spray box 3 through the discharge port.

[0079] After a battery to be cleaned with residual cleaning fluid is transported to the bottom of the movable frame 4 by the roller conveyor 2, the battery can be suspended from being transported by the flap 14, and the position of the battery in the front-to-back direction can be adapted to the cleaning frame 12, and then the movable frame 4 can be moved downward by the lifting module, and the movable frame 4 will drive the baffle 15 to move to the rear side of the battery located under the movable frame 4, thereby preventing the next battery from moving to the bottom of the movable frame 4 in advance, and then the battery can be lifted from the roller conveyor 2, and the position of the battery in the left-right direction can be adapted to the cleaning frame 12; then the cleaning fluid adhered to the four sides of the battery can be scraped off, and the flexible absorbent block 13 can be driven to move downward to the top of the battery to absorb the cleaning fluid remaining on the top of the battery, and the outer end of the air duct 17 can be connected to the blowing device to supply air to the blowing hood 16, so as to blow and clean the cleaning fluid remaining on the bottom surface of the battery detached from the roller conveyor 2.

[0080] Afterwards, the movable frame 4, the cleaning frame 12 and the flexible absorbent block 13 can be moved upward by a certain distance through the lifting module, so that the cleaning frame 12 is higher than the top of the battery. Then the battery can be returned to the roller conveyor 2, so that the battery can continue to be conveyed forward and the cleaned battery can be moved to the front side of the movable frame 4.

[0081] However, the baffle 15 will continue to block the next battery to prevent it from entering under the movable frame 4, and then the cleaning liquid absorbed by the flexible water-absorbing block 13 can be cleaned, and then the movable frame 4 can continue to move upward through the lifting module and reset, so that the baffle 15 releases the limit on the next battery, allowing the next battery to move to the bottom of the movable frame 4 and clean the residual cleaning liquid.
