[0047] See Figure 1 , Figure 1 The structure diagram of the fully automatic wiping device for the battery filling port according to one embodiment of the present invention is shown. The fully automatic wiping device for the battery filling port provided by one embodiment of the present invention includes: a frame 20, a feeding mechanism 30, a liquid spraying mechanism 40 and a wiping mechanism 50. The feeding mechanism 30 is arranged on the frame 20, and a plurality of guide devices 32 are installed on the feeding mechanism 30 along the conveying direction of the feeding mechanism 30. The liquid spraying mechanism 40 and the wiping mechanism 50 are installed on the feeding mechanism 30 in sequence along the conveying direction of the feeding mechanism 30. Figure 2 As shown, the battery 10 is a square structure, and the top of the battery 10 has an injection port 11 for injecting electrolyte. After the injection is completed, residual electrolyte or electrolyte crystals adhere to the injection port 11 and its surroundings, and need to be wiped to remove the residual electrolyte or electrolyte crystals. The feeding mechanism 30 first transports the battery 10 to the bottom of the spray structure, and the spray mechanism 40 sprays a cleaning liquid toward the injection port 11 of the battery 10 and its vicinity. The cleaning liquid is used to dissolve the residual electrolyte or electrolyte crystals to prevent the residual electrolyte or electrolyte crystals from adhering stubbornly and being difficult to wipe. The wiping mechanism 50 is installed on the upper side of the frame 20, and the wiping portion 53 of the wiping mechanism 50 extends to the top of the feeding structure. The wiping portion 53 wipes the residual electrolyte or electrolyte crystals adhering to the injection port 11 of the battery 10 on the feeding mechanism 30.

[0048] Continue reading Figure 1The frame 20 is a frame structure and also includes a circuit cabinet 21 mounted on one side. This cabinet houses circuits, processors, and other electronic components. At the bottom of the cabinet 21, there is at least one pair of universal rollers 211 capable of rotating and moving in any direction, allowing the cabinet 21 and the portion of the spray mechanism 40 and wiping mechanism 50 mounted on the circuit board to be moved relative to the frame 20. The rollers 211 also have a rotation stop to prevent the cabinet 21 from being stopped in a fixed position. The feeding mechanism 30 includes a conveyor belt 31 and a guide device 32. The conveyor belt 31 is mounted on the frame 20 to automatically transport the batteries 10. The guide device 32 is mounted above the conveyor belt 31. The guide device 32 includes a gantry 321, a screw 322, a guide bar 323, and a guide roller 324. The gantry 321 is mounted on the frame 20 and spans above the conveyor belt 31. Three guide bars 323 are mounted above the conveyor belt 31 via screws 322 along the conveyor belt 31's conveying direction. The spaces between adjacent guide bars 323 form a channel for the internal teeth to pass through. The three guide bars 323 form a dual channel, allowing two rows of batteries 10 to pass through the conveyor belt 31 simultaneously. The guide bars 323 are equipped with a number of guide rollers 324, arranged sequentially along their extension. The axes of the guide rollers 324 extend vertically and are rotatable about their respective axes. The gaps between the guide rollers 324 on adjacent guide bars 323 are adapted to the width of the batteries 10, ensuring that the batteries 10 passing through the channel abut against the circumferential sidewalls of the guide rollers 324. As the batteries 10 move along the conveyor belt 31, the guide rollers 324 adjust the battery 10's position so that the battery's filling port 11 faces the wiping mechanism 50. This prevents the battery 10 from moving sideways during wiping, which could result in poor wiping. The frame 20 also includes a beam that spans the conveyor belt 31. The beam has support legs on both sides. One support leg is mounted on the upper surface of the circuit cabinet 21, while the other support leg abuts the ground. The beam has several transversely extending beams. The spray mechanism 40 and the wiping mechanism 50 are both mounted on the beams. Different components of the spray mechanism 40 and the wiping mechanism 50 may be mounted on different beams.

[0049] See Figure 3 , Figure 3The figure shows a schematic structural diagram of the liquid spraying mechanism 40 in the fully automatic wiping device for the battery liquid filling port proposed in accordance with one embodiment of the present invention. The liquid spraying mechanism 40 is installed on a beam that spans the conveyor belt 31. The liquid spraying mechanism 40 includes: a liquid storage tank 41, a liquid pump 42, and a liquid spraying port 43. The liquid storage tank 41, the liquid pump 42, and the liquid spraying port 43 are sequentially installed from top to bottom on the beam directly above the conveyor belt 31. The liquid storage tank 41, the liquid pump 42, and the liquid spraying port 43 are connected in sequence by flexible water pipes. The number of the liquid storage tank 41, the liquid pump 42, and the liquid spraying port 43 is two each. A separate liquid storage tank 41, liquid pump 42, and liquid spraying port 43 constitute a separate liquid spraying system. The liquid storage tank 41 is a tank-shaped structure with a accommodating space inside, and an upward-facing liquid replenishing port 411 is provided on the top thereof for replenishing the cleaning liquid. The bottom of the liquid storage tank 41 is connected to the liquid inlet of the liquid pump 42 via a flexible water pipe. The liquid outlet of the liquid pump 42 is also connected to the liquid spray port 43 via a pipe. The liquid spray port 43 sprays liquid vertically downward. The installation position of the liquid spray port 43 on the beam directly faces the battery 10. The outlet of the liquid spray port 43 has a plurality of liquid holes. This ensures that the cleaning liquid particles sprayed from the liquid spray port 43 are small and evenly dispersed, evenly spraying the cleaning liquid around the liquid filling port 11 of the battery 10. When the liquid pump 42 is in operation, it draws cleaning liquid from the liquid storage tank 41 and sprays it out through the liquid spray port 43.

[0050] See Figure 4 、 Figure 5 As shown, the wiping mechanism 50 is installed above the rear side of the liquid spraying mechanism 40 in the conveying direction of the conveyor belt 31. The wiping mechanism 50 is installed on the beam frame. The wiping mechanism 50 includes: a vertical driving member 51, a driving guide rail 52, a wiping portion 53 and a cleaning device 54. The vertical driving member 51 is installed on the beam frame through the driving guide rail 52. The driving guide rail 52 drives the vertical driving member 51 to move back and forth along the extension direction of the crossbeam. A sliding plate 511 is installed at the driving end of the vertical driving member 51. The sliding plate 511 is driven by the vertical driving member 51 to move closer to or away from the conveyor belt 31. The wiping portion 53 is installed on the sliding plate 511. The wiping portion 53 enters or leaves the conveyor belt 31 area and approaches or moves away from the liquid filling port 11 of the battery 10 through the vertical driving member 51 and the driving guide rail 52, so that the wiping portion 53 can move freely in the vertical plane.

[0051] Combine Figure 6 As shown, Figure 6The present invention shows a schematic structural diagram of the wiping portion 53 in a fully automatic wiping device for a battery filling port according to an embodiment of the present invention. The wiping portion 53 is used to wipe residual electrolyte or electrolyte crystals around the filling port 11 of the battery 10. The wiping portion 53 includes a rotating drive portion 531, a transmission portion 532, and a wiping head 533. Rotating drive portion 531. The rotating drive portion 531 drives the wiping head 533 to rotate and wipe the filling port 11 of the battery 10 through the transmission portion 532 to achieve the cleaning purpose. The rotating drive portion 531 includes a first rotating drive member 5311 and a second rotating drive member 5312. The transmission portion 532 includes a first transmission member 5321 and a second transmission member 5322. The wiping head 533 includes two wet wiping heads 5331 and one dry wiping head 5332. The first rotary drive member 5311 is mounted on the side of the sliding plate 511 that is closer to the circuit cabinet 21. The first rotary drive member 5311 is drivingly connected to the first wet wiping head 5331 via the first transmission member 5321. The second rotary drive member 5312 is mounted side by side with the first rotary drive member 5311 on the side that is farther from the circuit cabinet 21. The second rotary drive member 5312 is drivingly connected to the second drive member. The second rotary drive member 5312 has a drive input end and two drive output ends. The drive input end is drivingly connected to the second rotary drive member 5312, and the two drive output ends are drivingly connected to the second wet wiping head 5331 and the dry wiping head 5332, respectively. The second wet wiping head 5331 is located closer to the first wet wiping head 5331. The second wet wiping head 5331 and the dry wiping head 5332 are arranged side by side with the first wet wiping head 5331, and the spacing between adjacent wiping heads 533 is equal to the spacing between the battery 10 injection ports 11 on the two channels of the conveyor belt 31. This ensures that when the wiping portion 53 approaches the battery 10, the two adjacent wiping heads 533 can simultaneously contact the battery 10 injection ports 11. The second driving member drives the wet wiping head 5331 and the dry wiping head 5332 to rotate synchronously via the second transmission member 5322.

[0052] Furthermore, the first transmission member 5321 is a single-output shaft reducer, and the second transmission member 5322 is a dual-output shaft reducer. Furthermore, the wet wiping head 5331 is a flexible brush head with good wiping performance, and the dry wiping head 5332 is a sponge head with good water absorption. In this embodiment, a wiping scheme using two wet wiping heads 5331 and a single dry wiping head 5332 is employed. Alternatively, a single wet wiping head 5331, two or more wet wiping heads 5331, or two or more dry wiping heads 5332 can be employed to ensure effective wiping, depending on the actual situation. The number of wet wiping heads 5331 and dry wiping heads 5332 is not limited herein.

[0053] Continue reading Figure 5As shown, after wiping the battery 10 filling port 11 multiple times, the wiping head 533 becomes contaminated by the dirty cleaning liquid after dissolving the electrolyte, making it difficult to continue wiping the battery 10 filling port 11. The wiping mechanism 50 also includes a cleaning device 54 for cleaning the wiping head 533 and restoring it to a clean state. The cleaning device 54 is a hollow rectangular parallelepiped structure with an upwardly open surface. The interior of the cleaning device 54 is divided into two independent spaces: a wet area 541 and a dry area 542. The wet area 541 is used to accommodate the wet wiping head 5331, and the dry area 542 is used to accommodate the dry wiping head 5332. When the drive rail 52 drives the wiping portion 53 away from the end of the drive rail 52 away from the motor cabinet, the wiping portion 53 is directly above the cleaning device 54. The vertical drive member 51 drives the wet wiping head 5331 and the dry wiping head 5332 to extend into the wet area 541 and dry area 542 of the cleaning device 54 respectively. The vertical drive member 51 and the drive rail 52 vibrate the wiping head 533 to remove most of the dirty cleaning liquid adhered to it. Cleaning parts with water-absorbing properties are also provided in the wet area 541 and the dry area 542. The cleaning parts abut against the wiping head 533, driving the wiping head 533 to rotate and wipe against the cleaning parts to achieve the purpose of the cleaning parts wiping the cleaning head 533. Specifically, the material of the cleaning parts is sponge. Furthermore, the cleaning method of the cleaning device 54 includes one or both of shaking to remove dirty cleaning liquid and using the cleaning parts to wipe and absorb dirty cleaning liquid, which is not limited here. Furthermore, the cleaning device 54 is detachably mounted on the frame 20 to facilitate cleaning the interior of the cleaning device 54 or replacing the cleaning components therein, thereby further increasing the service life of the wiping head 533 and reducing production and use costs.

[0054] Specifically, the wiping method of the battery filling port fully automatic wiping device of the present application includes the following steps:

[0055] Step 1: The conveyor belt 31 transports a pair of batteries 10 to the bottom of the liquid spraying mechanism 40 , and the liquid pump 42 works to suck the cleaning liquid from the liquid storage tank 41 and spray the cleaning liquid around the liquid injection port 11 of the battery 10 through the liquid spraying port 43 .

[0056] Step 2: The conveyor belt 31 continues to convey the battery 10 to the bottom of the wiping mechanism 50. The wiping part 53 is driven by the driving guide rail 52 at a higher position to directly above the liquid filling port 11 of the battery 10, so that the first wet wiping head 5331 is directly facing the liquid filling port 11 of the battery 10 on the side close to the circuit cabinet 21 of the two batteries 10. The vertical driving member 51 drives the wiping part 53 to approach the battery 10 until the first wet wiping head 5331 abuts against the liquid filling port 11 of the battery 10 and maintains a certain pressure on it. The first rotating driving member 5311 drives the first wet wiping head 5331 to rotate to complete a wet wiping of the liquid filling port 11 of the battery 10.

[0057] Step 3: After the vertical driving member 51 drives the wiping portion 53 to move a certain distance away from the battery 10, the driving guide rail 52 drives the vertical driving member 51 to move toward the circuit cabinet 21, so that the first wet wiping head 5331 and the second wet wiping head 5331 in the wiping portion 53 are respectively aligned with the liquid filling port 11 of the battery 10, and the vertical driving member 51 drives the wiping portion 53 close to the battery 10 until the wiping head 533 abuts against the liquid filling port 11 of the battery 10, so that the first wet wiping head 5331 completes one wet wiping of the liquid filling port 11 of the battery 10 away from the circuit cabinet 21, and the second wet wiping head 5331 completes a second wet wiping of the liquid filling port 11 of the battery 10 close to the circuit cabinet 21.

[0058] Step 4: After the vertical driving member 51 drives the wiping portion 53 to move a distance away from the battery 10, the driving guide rail 52 continues to drive the vertical driving member 51 to move toward the circuit cabinet 21, so that the second wet wiping head 5331 and the dry wiping head 5332 in the wiping portion 53 are respectively aligned with the liquid filling port 11 of the battery 10, and the vertical driving member 51 drives the wiping portion 53 to approach the battery 10 until the wiping head 533 abuts against the liquid filling port 11 of the battery 10, and drives the wiping head 533 to rotate and wipe, so that the second wet wiping head 5331 completes a second wet wiping of the liquid filling port 11 of the battery 10 away from the circuit cabinet 21, and the dry wiping head 5332 completes a dry wiping of the liquid filling port 11 of the battery 10 close to the circuit cabinet 21;

[0059] Step 5: After the vertical driving member 51 drives the wiping portion 53 to move a certain distance away from the battery 10, the driving guide rail 52 continues to drive the vertical driving member 51 to move toward the circuit cabinet 21, so that the dry wiping head 5332 is aligned with the liquid filling port 11 of the battery 10 close to the side of the circuit cabinet 21. The vertical driving member 51 drives the dry wiping head 5332 to approach the battery 10 until the dry wiping head 5332 abuts against the liquid filling port 11 of the battery 10. The second rotating driving member 5312 drives the dry wiping head 5332 to rotate and wipe, so that the dry wiping head 5332 completes dry wiping of the liquid filling port 11 of the battery 10 away from the circuit cabinet 21.

[0060] Step 6: After the wiping part 53 wipes the battery 10 , the driving guide rail 52 and the vertical driving member 51 drive the wiping head 533 to enter the cleaning device 54 , and the cleaning device 54 cleans the wiping head 533 .

[0061] Repeat the above steps 1 to 6 to achieve full automation of the battery filling port full-automatic wiping device of the present application, thereby greatly improving production efficiency.

[0062] The fully automatic wiping device for the battery filling port of the present application uses a double wet wiping head 5331 to wet-wipe the filling port 11 of the battery 10 multiple times to improve the wiping and cleaning effect; the dry wiping head 5332 performs dry wiping on the filling port 11 of the battery 10 to prevent residual cleaning liquid or electrolyte from causing secondary contamination of the filling port 11. The fully automatic wiping device for the battery filling port of the present application connects the second wet wiping head 5331 and the dry wiping head 5332 in parallel, and the rotation speed of the second wet wiping head 5331 and the dry wiping head 5332 is lower than that of the first wet wiping head 5331. This reduces the number of rotating drive parts without reducing the wiping and cleaning effect, thereby reducing production and maintenance costs. The fully automatic wiping device for the battery filling port of the present application uses a cleaning device 54 to clean the contaminated wiping head 533, so that the wiping head 533 can be reused, reducing the cost of use.

[0063] See Figure 7 , Figure 7 The figure shows a schematic diagram of the structure of a fully automatic wiping device for a battery filling port according to an embodiment of the present invention after a hood 60 is installed. The fully automatic wiping device for a battery filling port of the present application also includes a hood 60, which covers and wraps the outer periphery of the wiping mechanism 50. A control panel 61 is provided on the side of the hood 60 near the circuit cabinet 21.
