[0002] In the battery production process, one of the processes involved is battery filling. The role of lithium battery electrolyte is to conduct ions between the positive and negative electrodes and serve as a medium for charging and discharging. The filling process is to inject the battery electrolyte into the battery in a quantitative manner after the battery is assembled. The process can be divided into two steps. The first step is to inject the electrolyte into the battery, and the second step is to fully infiltrate the injected electrolyte with the battery's internal pole pieces and diaphragms. The duration of the infiltration will affect the production cost of lithium-ion batteries. In this process, too much injection can easily cause the battery to bulge and cause uneven battery thickness. Too little injection will lead to a reduction in battery capacity and cycle times, and uneven injection will lead to consistency differences in battery capacity and cycle performance. After the battery is filled, the battery's filling port and battery surface need to be cleaned to remove residual electrolyte and other substances on the surface, and then enter the next welding and sealing process to seal the filling port.

[0015] A battery post-filling cleaning machine comprises a battery post-filling wiping device.

[0016] The beneficial effects of the present invention are: In view of the defects and shortcomings of the prior art, the present invention independently developed and designed a battery post-filling wiping device and a battery post-filling cleaning machine, which utilizes the movement of a single wiping belt to achieve synchronous and continuous wiping and cleaning of multiple battery filling ports, thereby improving cleaning efficiency and continuity, and has an overall flipping function, thereby achieving angle adjustment while improving belt changing efficiency, and achieving load bearing and limiting during the flipping process through an arc-shaped load-bearing surface, thereby effectively reducing the energy consumption of the flipping drive while ensuring the accuracy of the flipping position, and ensuring flexible contact between the wiping belt and the battery filling port through flexible contact and integrated rotating belt abutment, while improving local cleaning effect.

[0017] The present invention aims to provide a battery filling process section applied to the field of new energy batteries, which belongs to a cleaning device after battery filling, and its function is to realize automatic cleaning of the battery filling port after the filling is completed. Specifically, the present invention uses a U-shaped box-shaped frame wiping bracket with an opening facing upward as a supporting structure. A lifting slide is slidably arranged in the vertical direction in the wiping bracket. The U-shaped box-shaped frame structure with the liquid level opening facing upward of the lifting slide is driven by the power output of the lifting motor arranged below to move up and down in the vertical direction, so as to drive the lifting and lowering of the wiping support, the flip assembly and the wiping assembly arranged horizontally on its upper part, so as to realize the movement in the vertical direction, so as to approach or move away from the battery on the battery platform; the present invention has an angle flipping function, which can not only realize the angle adjustment of the wiping assembly, but also facilitate its switching in the vertical and horizontal directions. It is convenient to wipe the battery filling port in the vertical direction, and it is convenient to disassemble and replace the wiping material belt when rotating to the horizontal direction; the special thing is that the flipping method of the present invention is compared with the traditional flipping method in that the tilted top cylinder arranged at both ends outputs linear power to realize the flipping drive of the wiping support plate. This driving method converts the simple cylinder linear drive into the rotation drive of the wiping support, and at the same time utilizes the rotatable setting at both ends of the tilted top cylinder to effectively avoid the motion interference in the power output process. Furthermore, during the flipping process of the wiping support plate, it has an arc-shaped guiding support function along the direction of its movement trajectory, that is, by respectively arranging arc-shaped support plates on the left and right sides of the wiping support platform, roller supports are respectively arranged on the left and right sides of the wiping support plate above the arc-shaped support plate, and the support rollers rotatably arranged on the roller supports contact the arc-shaped support plate. During the rotation of the flipping support plate, the support rollers roll along the arc-shaped supporting surface at the top of the arc-shaped support plate. By using the arc-shaped supporting surface along the flipping path direction of the flipping support plate, the flipping process of the flipping support plate is realized without interfering with its flipping movement. The real-time rolling support in the device can effectively share part of the gravity of the flip support plate, reduce the power output demand, and reduce the energy consumption of the equipment; at the same time, through the guide rollers respectively arranged on both sides of the support roller, the two guide rollers roll along the left and right side walls of the arc-shaped support plate during the flipping process of the flip support plate, thereby realizing the left and right limit guiding of the flip support plate, which can effectively ensure the stability of the position angle of the flip support plate during the flipping process, improve its displacement accuracy, and the use of rolling contact with the arc-shaped support plate can effectively reduce the friction resistance in the guiding process and avoid motion interference. Furthermore, the cleaning method adopted by the present invention is to use the wiping belt body in motion to contact and rub the surface of the battery filling port when passing through the surface of the battery filling port, so as to complete the liquid absorption at the battery filling port and wipe its surface;Specifically, the belt body component is used as the releasing and collecting structure of the wiping belt body, and the wiping belt body is released and collected by the first reel and the second reel which are arranged on the side wall of the wiping support plate at intervals. For example, the clean belt body which has not been wiped clean is wound on the first reel, and is connected to the second reel after passing through a plurality of tensioning rollers arranged on the wiping support plate. In the process of the second reel rotating to pull out the wiping belt body and winding up the wiping belt body, the wiping belt body is pulled out and the automatic collection of the wiping belt body after wiping and cleaning is realized. In the process of leading out the wiping belt body, the pressure roller and the adjustment roller which are arranged on the wiping support plate are passed through. When the wiping belt body passes through the gap space between the pressure roller and the adjustment roller, it is pressed and fixed by the two rollers, and the pressure roller has the function of actively rotating The function is that when the pressure roller rotates, the static friction force is used to assist in pulling out the wiping belt body, and the tension of the wiping belt body can be adjusted in real time. In view of the process requirements of wiping multiple battery filling ports synchronously, the present invention arranges multiple groups of tensioning rollers in the vertical direction on the wiping support plate. When the wiping belt body passes through the multiple groups of tensioning rollers, multiple vertical spaces spaced apart from each other are formed. Wiping components are respectively provided in the multiple vertical spaces. When the wiping belt body moves to the bottom of the wiping component, the wiping component outputs downward power to push the wiping belt body downward and tighten it, and make it close to the battery filling port. When the wiping belt body passes through the battery filling port during movement, the friction between the belt surface and the battery filling port is used to complete the wiping. Automatic cleaning at the battery filling port; the wiping component is connected to the side wall of the wiping support plate with a wiping vertical plate, and the wiping cylinder vertically arranged on the wiping vertical plate and with the output end facing downward outputs downward power to drive the wiping driving seat to move up and down, and the wiping driving seat drives the wiping slide connected thereto to move up and down, and the wiping slide drives the wiping rod arranged at its lower end to move up and down, so that after the lower end of the wiping rod is against the upper belt surface of the wiping belt body, the wiping belt body is close to the battery filling port; the special feature of the wiping slide of the present invention is that it has an adaptive adjustment function in the vertical direction, that is, the wiping slide is movably connected to the wiping driving seat in the vertical direction, and is adjusted by a wiping spring arranged on its top and a wiping extension extending horizontally on the side wall of the wiping driving seat. The wiping slide is connected with an extension block; the movable elastic setting mode of the wiping slide makes the wiping rod and the wiping belt body realize flexible contact with the battery filling port, and the elastic buffer provided by the wiping spring can effectively avoid collision and extrusion of the battery filling port during the contact process, and when the wiping slide drives the wiping rod to move downward to push the wiping belt body to the battery filling port, the upward reaction force of the battery filling port on the wiping rod pushes the wiping slide upward, so that the wiping spring is in a compressed state, and the elastic force of the wiping spring in the compressed state has a tendency to push the wiping slide downward in the opposite direction, so that the wiping rod and the wiping belt body maintain continuous downward pressure on the battery filling port, so as to ensure the contact stability between the wiping belt body and the battery filling port during the wiping and cleaning process;In addition, the wiping slide of the present invention is an L-shaped structure, the vertical side wall of which is slidably connected to the wiping drive seat, and the horizontal side wall of which is provided with a rotary motor with an output end facing downward, the wiping rod is connected to the output end of the rotary motor, and is driven by the rotary motor to rotate, and while the wiping rod pushes the wiping belt downward, its lower end surface drives the wiping belt to contact the battery liquid injection port, and then rotates on the upper surface of the wiping belt to improve the cleaning effect of the wiping belt at the battery liquid injection port; in addition, an auxiliary part is also provided on one side of the wiping rod, and the auxiliary part drives the auxiliary slider through the auxiliary cylinder to drive the auxiliary block to press the wiping belt downward through the guide slope at the bottom of the wiping rod, and while adjusting the tension of the wiping belt, a plurality of air holes are arranged at the bottom of the guide slope for blowing out high-pressure gas, which simultaneously realizes the self-cleaning and drying of the wiping belt, and effectively ensures the cleaning effect of the wiping belt. ; BRIEF DESCRIPTION OF THE DRAWINGS

Example 5

[0038] As an embodiment of the present invention, the present invention discloses a battery post-filling cleaning machine including a battery post-filling wiping device.

[0039] Furthermore, the present invention designs a battery post-filling wiping device and a battery post-filling cleaning machine that utilizes the movement of a single wiping belt to achieve synchronous and continuous wiping and cleaning of multiple battery filling ports, thereby improving cleaning efficiency and continuity, and having an overall flipping function, achieving angle adjustment while improving belt changing efficiency, and realizing load bearing and position limiting during flipping through an arc-shaped bearing surface, effectively reducing flipping drive energy consumption while ensuring flipping position accuracy, and ensuring flexible contact between the wiping belt and the battery filling port through flexible contact and integrated rotating belt contact while improving local cleaning effect. The present invention aims to provide a battery filling process section applied to the field of new energy batteries, which belongs to a battery post-filling cleaning device, and its function is to achieve automatic cleaning of the battery filling port after the filling is completed. Specifically, the present invention uses a U-shaped box-shaped frame wiping bracket with an opening facing upward as a supporting structure. A lifting slide is slidably arranged in the vertical direction in the wiping bracket. The U-shaped box-shaped frame structure with the liquid level opening facing upward of the lifting slide is driven by the power output of the lifting motor arranged below to move up and down in the vertical direction, so as to drive the lifting and lowering of the wiping support, the flip assembly and the wiping assembly arranged horizontally on its upper part, so as to realize the movement in the vertical direction, so as to approach or move away from the battery on the battery platform; the present invention has an angle flipping function, which can not only realize the angle adjustment of the wiping assembly, but also facilitate its switching in the vertical and horizontal directions. It is convenient to wipe the battery filling port in the vertical direction, and it is convenient to disassemble and replace the wiping material belt when rotating to the horizontal direction; the special thing is that the flipping method of the present invention is compared with the traditional flipping method in that the tilted top cylinder arranged at both ends outputs linear power to realize the flipping drive of the wiping support plate. This driving method converts the simple cylinder linear drive into the rotation drive of the wiping support, and at the same time utilizes the rotatable setting at both ends of the tilted top cylinder to effectively avoid the motion interference in the power output process. Furthermore, during the flipping process of the wiping support plate, an arc-shaped guiding support function is provided along the direction of its motion trajectory, that is, by respectively arranging arc-shaped support plates on the left and right sides of the wiping support platform, roller supports are respectively provided on the left and right sides of the wiping support plate located above the arc-shaped support plate, and the arc-shaped support plate is contacted by the support rollers rotatably arranged on the roller supports. During the rotation of the flipping support plate, the support rollers roll along the arc-shaped support surface at the top of the arc-shaped support plate. By using the arc-shaped support surface along the flipping path direction of the flipping support plate, real-time rolling support of the flipping support plate during the flipping process is achieved without interfering with its flipping motion, which can effectively share part of the gravity of the flipping support plate, reduce the power output demand, and reduce the energy consumption of the equipment.At the same time, by means of guide rollers respectively arranged on both sides of the support roller, the two guide rollers roll along the left and right side walls of the arc-shaped support plate as the flipping support plate flips, thereby realizing the left and right limit guiding of the flipping support plate, which can effectively ensure the stability of the position angle during the flipping process of the flipping support plate and improve its displacement accuracy. In addition, the use of a rolling contact arc-shaped support plate can effectively reduce the friction resistance during the guiding process and avoid motion interference. Furthermore, the cleaning method adopted by the present invention is to use the wiping belt body to contact and rub against the surface of the battery filling port when the moving wiping belt body passes through the surface of the battery filling port, so as to complete the liquid absorption at the battery filling port and wipe its surface; specifically, the belt body component is used as the release and collection structure of the wiping belt body, and the wiping belt body is released and collected by the first reel and the second reel arranged at intervals on the side wall of the wiping support plate. For example, the first reel is wound with a clean belt body that has not been wiped and cleaned. After passing through a plurality of tensioning rollers arranged on the wiping support plate, it is connected to the second reel, and the second reel rotates and moves In the process of automatically pulling out the wiping belt and winding the wiping belt, the wiping belt is pulled out and the wiping belt is automatically collected after wiping and cleaning; in the process of leading out the wiping belt, the pressure roller and the adjustment roller arranged on the wiping support plate are used, and the wiping belt is pressed and fixed by the pressure roller and the adjustment roller when passing through the gap space between the pressure roller and the adjustment roller. At the same time, the pressure roller has an active rotation function. When the pressure roller rotates, the static friction force is used to assist in pulling out the wiping belt, and the tension of the wiping belt can also be adjusted in real time. In view of the process requirements of wiping multiple battery filling ports synchronously, the present invention adopts A plurality of tensioning rollers are arranged vertically up and down on the wiping support plate, and a plurality of vertical spaces spaced apart from each other are formed when the wiping belt passes through the plurality of tensioning rollers. Wiping components are respectively arranged in the plurality of vertical spaces. When the wiping belt moves to the bottom of the wiping component, the wiping component outputs a downward force to push the wiping belt downward and tighten it, and make it close to the battery filling port. When the wiping belt passes through the battery filling port during its movement, the friction between the surface of the belt and the battery filling port is used to complete the automatic cleaning of the battery filling port. The wiping component is connected to the side wall of the wiping support plate with a wiping vertical plate, and a plurality of vertical spaces are arranged vertically on the wiping vertical plate. The wiping cylinder with the output end facing downward outputs downward power to drive the wiping driving seat to move up and down, the wiping driving seat drives the wiping slide connected thereto to move up and down, and the wiping slide drives the wiping rod arranged at its lower end to move up and down, so that after the lower end of the wiping rod abuts against the upper belt surface of the wiping belt body, the wiping belt body is close to the battery filling port; the special feature of the wiping slide of the present invention is that it has an adaptive adjustment function in the vertical direction, that is, the wiping slide is movably connected to the wiping driving seat in the vertical direction, and is connected to the wiping extension block horizontally extending from the side wall of the wiping driving seat through a wiping spring arranged at the top thereof;The movable elastic setting mode of the wiping slide seat enables the wiping rod and the wiping belt body to achieve flexible contact with the battery filling port. The elastic buffer provided by the wiping spring can effectively avoid collision and squeezing of the battery filling port during the contact process. When the wiping slide seat drives the wiping rod to move downward to push the wiping belt body to the battery filling port, the upward reaction force of the battery filling port on the wiping rod pushes the wiping slide seat upward, so that the wiping spring is in a compressed state. The elastic force of the wiping spring in the compressed state has a tendency to push the wiping slide seat downward in the opposite direction, so that the wiping rod and the wiping belt body maintain continuous downward pressure on the battery filling port to ensure the contact stability of the wiping belt body and the battery filling port during the wiping and cleaning process. In addition, the wiping slide seat of the present invention is an L-shaped structure, and its vertical side wall and the wiping drive seat can be The sliding connection has a rotating motor with an output end facing downwards on its horizontal side wall. The wiping rod is connected to the output end of the rotating motor and is driven by the rotating motor to rotate. While the wiping rod pushes the wiping belt downwards, its lower end surface drives the wiping belt to contact the battery liquid injection port and rotate on the upper surface of the wiping belt to improve the cleaning effect of the wiping belt at the battery liquid injection port. In addition, an auxiliary part is also provided on one side of the wiping rod. The auxiliary part drives the auxiliary slider through the auxiliary cylinder to drive the auxiliary block to press the wiping belt downward through the guide slope at the bottom of the wiping rod. While adjusting the tension of the wiping belt, a plurality of air holes are arranged at the bottom of the guide slope for blowing out high-pressure gas, which simultaneously realizes the self-cleaning and drying of the wiping belt, and effectively ensures the cleaning effect of the wiping belt. ;
