Description

[Technical Field]

[0001] The present invention relates to the technical field of battery manufacturing, and more particularly to an apparatus for acid immersion of electrode plates for battery manufacturing. [Background technology]

[0002] In the battery manufacturing process, positive and negative electrode pastes are sprayed onto the grids, and then the electrodes are formed. Before the electrodes are dried, they are placed in an acid bath containing concentrated sulfuric acid. The positive and negative electrode pastes react with the concentrated sulfuric acid to form a thin layer of lead sulfate on the surface of the electrodes. This lead sulfate prevents cracks in the electrodes and improves their strength.

[0003] In conventional acid immersion methods, electrodes are manually placed into an acid immersion tank, which is then placed into an acid immersion bath for reaction. This method requires a large manual workload and is prone to injury due to contact with concentrated sulfuric acid during transportation. Currently, a belt conveyor is often installed inside the acid immersion bath, and the acid immersion tank, which has a hollow hole in the bottom, is moved by the conveyor belt, causing the electrode paste on the electrodes to react with concentrated sulfuric acid during transportation. However, this method still has the following problems.

[0004] 1. The friction force of the belt conveyor is insufficient during the process of transporting the acid soaking tank, causing the acid soaking tank to pile up in the acid soaking tank, which requires manual assistance to ensure smooth operation of the belt conveyor and affects the transport efficiency.

[0005] 2. A certain amount of concentrated sulfuric acid remains in the acid immersion tank, which corrodes other equipment during the subsequent transportation process and also affects the drying time of the subsequent plates. Summary of the Invention [Problem to be solved by the invention]

DETAILED DESCRIPTION OF THE INVENTION

[0024] The following clearly and completely describes the technical solutions in the embodiments of the present invention, in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and are not all embodiments.

[0025] In describing the present invention, it should be understood that the orientations or positional relationships indicated by the terms "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," "outer," etc. are orientations or positional relationships shown based on the drawings, and are intended merely to facilitate and simplify the description of the present invention, and do not suggest or imply that the devices or elements referred to have a particular orientation or must be configured and operated in a particular orientation, and should not be understood as limitations on the present invention. [Example]

[0026] 1 to 7, the apparatus for acid-soaking electrodes for manufacturing storage batteries includes an acid-soaking tank 1, a bracket 4 for supporting electrodes that is installed in the acid-soaking tank 1, and floating rolls 3 that are arranged equidistantly within the bracket 4.

[0027] In this embodiment, multiple sets of floating rolls 3 are used to support the acid immersion tank, and the acid immersion tank and the supporting floating rolls 3 have a line contact structure, which ensures that the acid immersion tank is surrounded by concentrated sulfuric acid as much as possible, so that the electrodes inside are fully immersed and the acid immersion effect is improved.

[0028] The traction assembly includes two sets of traction ropes 9, a first lug plate 6 and a second lug plate 7 fixedly attached above the bracket 4 and above the acid bath 1, respectively, a pulley 8 rotatably attached to one side of each of the first lug plate 6 and the second lug plate 7, the traction ropes 9 being wound around the pulleys 8, two sets of first guide bars 5 symmetrically installed on one side of the bracket 4, the first guide bars 5 being slidably attached to the acid bath 1, and a floating roll 3 rotatably installed between the two sets of brackets 4.

[0029] In this embodiment, the floating roll 3 is slidably mounted in the acid immersion tank 1 via a bracket 4, and is wound around the pulley 8 via a traction rope 9. When the first motor 11 is started, the traction rope 9 is pulled to lower or raise the floating roll 3.

[0030] This acid immersion apparatus further includes a traction assembly for driving the lifting and lowering of the roll frame, and the traction assembly further includes a first motor 11 fixedly attached to the outer wall of the acid immersion tank 1, with a traction shaft 10 drivably connected to the output end of the first motor 11, the traction shaft 10 being rotatably attached to the outer wall of the acid immersion tank 1, and pulleys 8 being fixedly attached to both ends of the traction shaft 10, and cylinders 12 are symmetrically attached to the outer wall of the acid immersion tank 1, located on both sides of the first motor 11.

[0031] In this embodiment, the specific steps for controlling the acid dip tank are as follows:

[0032] The first motor 11 is started, and the first motor 11 drives the traction shaft 10 to rotate, causing the pulleys 8 on both ends of the traction shaft 10 to rotate and loosen the traction rope 9, one end of which is connected to the pulley 8 on the first lug plate 6. Thus, after the acid immersion tank is placed on the floating roll 3, the floating roll 3 supports the acid immersion tank to sink under the action of gravity, thereby completely immersing the battery plates in the acid immersion tank 1.

[0033] After the acid immersion treatment, the first motor 11 is started to drive in the reverse direction, causing the pulleys 8 on both ends of the traction shaft 10 to rotate and wind up the traction rope 9, thereby pulling the first lug plate 6, pulling the brackets 4 on both sides, the floating roll 3 between the two sets of brackets 4, and the acid immersion tank to rise up to outside the concentrated sulfuric acid, and the cylinder 12 is started to push the acid immersion tank above the cleaning tank 2.

[0034] A transport assembly is installed in the cleaning tank 2, and a shower assembly is installed on one side of the transport assembly to remove concentrated sulfuric acid remaining on the surface of the acid immersion tank.

[0035] In this embodiment, a cleaning tank 2 is added to one side of the acid immersion tank 1, and a shower assembly installed in the cleaning tank 2 is used to clean the surface of the acid immersion tank of residual concentrated sulfuric acid, thereby preventing corrosion of other equipment during the subsequent transportation process and simultaneously shortening the drying time of the subsequent electrode plates.

[0036] The transport assembly includes a cleaning roll 13, on the surface of which ribs 32 are arranged at equal intervals in a circular pattern. The cleaning roll 13 is installed as a hollow roll, and drainage holes 39 are opened in each of the cleaning rolls 13 at positions that avoid the ribs 32.

[0037] In this embodiment, cleaning rolls 13 are installed in the cleaning tank 2, and adjacent cleaning rolls 13 are connected to each other so that they can be driven. The cleaning rolls 13 are used to clean the acid immersion tank after acid immersion. At the same time, the cleaning rolls 13 are installed in a hollow structure, and a water pump is used to inject water into the cleaning rolls 13. The water is then directed through drainage holes 39 to hit the bottom of the acid immersion tank, thereby cleaning surfaces that are difficult to clean and effectively removing concentrated sulfuric acid remaining on the surface of the acid immersion tank.

[0038] A first water distribution pipe 14 is connected to one end of the cleaning roll 13, and the bottom of the first water distribution pipe 14 is connected to a peristaltic pump 40 via an upper water distribution pipe 33. The peristaltic pump 40 is fixedly attached to one side of the outer wall of the cleaning tank 2, and a filter 34 is connected to the bottom end of the upper water distribution pipe 33.

[0039] In this embodiment, the peristaltic pump 40 is started, and the cleaning liquid in the cleaning tank 2 is sucked into the first drain pipe 14 through the upper drain pipe 33 equipped with the filter 34, and then injected into the cleaning rolls 13, respectively. As the cleaning rolls 13 rotate, they come into contact with the acid soaking tank using the ribs 32 and move the acid soaking tank to continuously transport it to the subsequent battery manufacturing process. At the same time, the ribs 32 push the acid soaking tank up to a certain height, thereby utilizing the gap between the cleaning rolls 13 and the acid soaking tank to facilitate water flow out of the drain hole 39 and wash the residue in the acid soaking tank as thoroughly as possible.

[0040] A third synchronous pulley 37 and a fourth synchronous pulley 38 are fixedly attached to one end of the cleaning rolls 13, a third motor 35 is fixedly attached to one side of the outside of the cleaning tank 2, a second synchronous pulley 36 is fixedly attached to the output shaft end of the third motor 35, the second synchronous pulley 36 is operably connected to the third synchronous pulley 37 at the end of one set of cleaning rolls 13, and adjacent fourth synchronous pulleys 38 are operably connected.

[0041] A third synchronous pulley 37 and a fourth synchronous pulley 38 are fixedly attached to one end of each of the cleaning rolls 13, and adjacent third synchronous pulleys 37 are connected in a transmission-like manner, and adjacent fourth synchronous pulleys 38 are also connected in a transmission-like manner. At the same time, the ends of one pair of cleaning rolls 13 are connected in a transmission-like manner via the third synchronous pulley 37 and the second synchronous pulley 36, which start a third motor 35, which drives the second synchronous pulley 36 at the end of its shaft to rotate, thereby driving the cleaning rolls 13 to rotate and transport them through the acid immersion tank.

[0042] The shower assembly includes a main pipe 17 that is symmetrical vertically. One side of the main pipe 17 is connected to a branch pipe 19 via a pressure booster valve 18. One end of the branch pipe 19 is connected to a nozzle 20. A rotary drive assembly is installed between the cleaning tank 2 and the main pipe 17. The rotary drive assembly includes two sets of meshed racks 24 and two sets of first gears 23. The two sets of first gears 23 are fixedly attached to one end of the two main pipes 17. A guide wheel 25 is rotatably attached to the other end of the main pipe 17. The guide wheel 25 is slidably connected to a second guide bar 22.

[0043] In this embodiment, a shower assembly is installed on one side of the transport assembly, and two sets of rotatable main pipes 17 are installed. A branch pipe 19 and a nozzle 20 are connected to one side of the main pipe 17. The cleaning liquid is injected into the main pipe 17 and then sprayed into the acid immersion tank through the branch pipe 19 and the nozzle 20. At the same time, a booster valve 18 is installed in the branch pipe 19 to increase the impact force of the shower and clean as thoroughly as possible the concentrated sulfuric acid remaining on the surface of the acid immersion tank.

[0044] The shower assembly further includes two sets of positioning plates 15 symmetrically installed on one side of the inner wall of the washing tank 2, second drainage pipes 16 fixedly mounted in the positioning plates 15, a main pipe 17 rotatably connected and communicating between the two sets of second drainage pipes 16, and the second drainage pipes 16 are installed in communication with a peristaltic pump 40.

[0045] The two sets of main pipes 17 are connected between the two sets of second water distribution pipes 16 so as to be rotatable, and after the peristaltic pump 40 and the second water distribution pipes 16 are connected, the cleaning liquid is simultaneously injected into the main pipes 17.

[0046] A fixed frame 21 is fixedly attached to one side of the cleaning tank 2, and a second guide bar 22 is installed on one side of the fixed frame 21 and on the inner wall of the cleaning tank 2. A rack 24 is slidably attached within the second guide bar 22. A screw 28 is connected to one end of each of the two sets of racks 24, and the two sets of screws 28 are threadedly connected to internally threaded sleeves 27. A second gear 26 is connected to the surface of the internally threaded sleeve 27. A second motor 29 is attached to the outer wall of the cleaning tank 2, and a drive rod 30 is rotatably attached within the cleaning tank 2. A first synchronous pulley 31 is fixedly connected to the output shaft end of the second motor 29 and one end of the drive rod 30. The two sets of first synchronous pulleys 31 are connected in a transmission-capable manner. An internally threaded sleeve 27 is connected to one end of the drive rod 30, and the internally threaded sleeve 27 engages with the second gear 26. The drive rod 30 is located on one side of the fixed frame 21.

[0047] In this embodiment, the rotary drive assembly drives the main pipe 17 to rotate at a certain angle, preferably ±55°. Specifically, the second motor 29 is started, and the second motor 29 drives the first synchronous pulley 31 at the output shaft end thereof to rotate, which transmits power to the first synchronous pulley 31 at the shaft end of the drive rod 30, thereby driving the drive rod 30 to rotate. A second gear 26 is installed at one end of the drive rod 30, and a second gear 26 is also fixedly attached to the surface of the female threaded sleeve 27. The two sets of second gears 26 engage with each other, driving the female threaded sleeve 27 to rotate on one side of the inner wall of the cleaning tank 2, and the two sets of screws 2 8 are respectively installed as left-handed male screws and right-handed male screws, and the inner wall of the female threaded sleeve 27 is provided with left-handed female screws and right-handed female screws that are compatible with the left-handed male screws and right-handed male screws, so that by using the forward and reverse rotation of the second motor 29 to rotate the female threaded sleeve 27, the two sets of first racks 24 can be moved closer to or farther away from each other, thereby driving the first gear 23 to rotate forward and reverse, and finally realizing that the two sets of upper and lower main pipes 17 can rotate forward and reverse within a certain angular range.

[0048] In the present invention, in the initial position, the floating roll 3 is suspended horizontally above the acid bath 1, and the acid solution such as concentrated sulfuric acid in the acid bath and the acid bath 1 is released. The acid bath is then placed on the floating roll 3, and the first motor 11 is started. The first motor 11 drives the traction shaft 10 to rotate, causing the pulleys 8 on both ends of the traction shaft 10 to rotate and loosen the traction rope 9. One end of the traction rope 9 is connected to the pulley 8 on the first lug plate 6. Therefore, after the acid bath is placed on the floating roll 3, the floating roll 3 supports the acid bath to sink under the action of gravity, thereby completely immersing the battery plates in the acid bath 1.

[0049] After the acid immersion treatment, the first motor 11 is started to drive in the reverse direction, the pulleys 8 on both ends of the traction shaft 10 rotate to wind up the traction rope 9, thereby pulling the first lug plate 6, pulling the brackets 4 on both sides, the floating roll 3 between the two sets of brackets 4, and the acid immersion tank to rise up to outside the concentrated sulfuric acid, and the cylinder 12 is started to push the acid immersion tank to above the cleaning tank 2. The peristaltic pump 40 is started, and the cleaning liquid in the cleaning tank 2 is sucked into the first drain pipe 14 through the upper drain pipe 33 equipped with the filter 34, and then injected into the cleaning rolls 13, respectively. As the cleaning rolls 13 rotate, they come into contact with the acid soaking tank using the ribs 32, and move the acid soaking tank to continuously transport it to the subsequent battery manufacturing process. At the same time, the ribs 32 push the acid soaking tank up to a certain height, thereby utilizing the gap between the cleaning rolls 13 and the acid soaking tank to facilitate water flow out of the drain hole 39, and thoroughly clean the acid soaking tank as much as possible. The second motor 29 is started and rotated forward and backward, causing the female thread sleeve 27 to rotate, thereby moving the two sets of first racks 24 closer to or farther from each other, thereby driving the first gear 23 to rotate forward and backward, and finally realizing that the two sets of upper and lower main pipes 17 can rotate forward and backward within a certain angular range.

[0050] The peristaltic pump 40 injects the cleaning liquid into the second drain pipe 16, then into the main pipe 17, and then sprays it into the acid immersion tank through the branch pipe 19 and the nozzle 20. At the same time, a booster valve 18 is installed in the branch pipe 19 to increase the impact force of the shower, so as to thoroughly clean the concentrated sulfuric acid remaining on the surface of the acid immersion tank. The second motor 29 drives the first synchronous pulley 31 at the end of its output shaft to rotate, transmitting power to the first synchronous pulley 31 at the shaft end of the drive rod 30, thereby rotating the drive rod 30. The drive rod 30 drives the female threaded sleeve 27 to rotate on one side of the inner wall of the washing tank 2. The two sets of screws 28 are respectively installed as left-handed male screws and right-handed male screws, and the inner wall of the female threaded sleeve 27 is respectively provided with left-handed female threads and right-handed female threads that match the left-handed male threads and right-handed male threads. Therefore, by using the forward and reverse rotation of the second motor 29, the female threaded sleeve 27 rotates to move the two sets of first racks 24 closer to or farther away from each other, thereby driving the first gear 23 to rotate forward and reverse, finally allowing the two sets of upper and lower main pipes 17 to rotate forward and reverse within a certain angular range, ensuring as large a shower cleaning range as possible.
