Description

Technical Field

[0001] This invention relates to the field of battery repair technology, specifically a device for precisely adding battery repair fluid. Background Technology

[0002] Lead-acid flooded batteries, commonly known as water batteries or open-type lead-acid batteries, are the most traditional type of lead-acid batteries. Their core feature is that the plates are completely immersed in free dilute sulfuric acid electrolyte, with abundant electrolyte that can flow freely. They have an opening at the top for filling. When repairing lead-acid flooded batteries, a precise filling device is required.

[0003] Currently, before adding repair fluid, workers typically need to manually measure sulfuric acid stock solution, pure water, and functional additives using simple tools such as measuring cups, syringes, and hydrometers. They then manually mix the components based on their experience, repeatedly measuring the sulfuric acid density before manually adding the solution. While this method can add repair fluid, the entire process of mixing the solution involves manual measurement and proportioning, resulting in poor accuracy and a tendency for the sulfuric acid density to be too high or too low, directly affecting the battery repair effect. Furthermore, the process is tedious and time-consuming, relying entirely on the operator's experience. The concentration of the repair fluid prepared by different personnel is inconsistent, leading to unstable quality during batch repairs. In addition, manual mixing is labor-intensive and inefficient. Moreover, the corrosive nature of sulfuric acid stock solution poses a risk of splashing and burns during manual operation, reducing the safety of the battery repair process.

[0004] Based on this, a precise battery repair fluid filling device is now provided, which can eliminate the drawbacks of existing devices. Summary of the Invention

[0025] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0026] In one embodiment, such as Figures 1-7 As shown, a precise filling device for battery repair fluid includes a placement base 1, a lifting plate 4 above the placement base 1, a mixing cylinder 5 and a pump 6 respectively installed on the upper surface of the lifting plate 4, a base plate 7 fixedly connected to the bottom of the lifting plate 4, and multiple filling heads 8 fixedly installed inside the base plate 7. The inlet end of the pump 6 is connected to the bottom of the mixing cylinder 5 through a pipe, and the outlet end of the pump 6 is connected to the upper surface of the multiple filling heads 8 through a pipe. A support frame 9 is fixedly installed on the upper surface of the lifting plate 4. The device also includes: A quantitative mixing component is installed on the support frame 9 and is used to quantitatively mix the repair fluid raw materials; The quantitative proportioning component includes multiple proportioning boxes 10 mounted on top of the support frame 9. Mounting sleeves 23 are fixedly connected to the surface of each proportioning box 10. Lowering frames 24 are symmetrically mounted on the surface of the mounting sleeves 23. Weighing sensors 25 are located below the lowering frames 24. The bottom of the weighing sensors 25 is fixedly connected to the upper surface of the support frame 9. Side plates 26 are symmetrically mounted on the surface of the mounting sleeves 23. Multiple damping rods 27 are fixedly connected to the upper surface of the support frame 9. The telescopic ends of the damping rods 27 are fixedly connected to the bottom of the side plates 26. Return springs 28 are sleeved around the damping rods 27 and abut against the side plates 26 and the support frame 9. The bottom of the proportioning box 10 is connected to the upper surface of the mixing cylinder 5 via a first solenoid valve 16 and a connecting pipe 17. In this embodiment, when the original solution of the repair fluid enters the mixing tank 10, the weight of the original solution causes the mixing tank 10 to shift downwards. At this time, the mixing tank 10 will drive the mounting sleeve 23 to move synchronously, and the mounting sleeve 23 will then drive the lower pressure frame 24 to move synchronously. When the bottom of the lower pressure frame 24 touches the upper surface of the weighing sensor 25, the weighing sensor 25 can weigh and quantify the original solution in the mixing tank 10. When the weight of the original solution reaches the specified standard, the weighing sensor 25 will transmit a signal to the controller, and the controller will then control the first solenoid valve 16 to open, at which point the quantification is completed. The original solution will enter the mixing cylinder 5, which can effectively perform quantitative proportioning of different original solutions, improve the accuracy and efficiency of the repair solution proportioning, and eliminate the tedious operation of manual measurement, mixing and repeated density measurement, significantly reducing the workload of the staff. During the downward movement of the installation sleeve 23, it will also drive the side plate 26 to move synchronously. At this time, the side plate 26 will squeeze the damping rod 27 and the return spring 28 synchronously. When the original solution in the proportioning box 10 enters the mixing cylinder 5, the return spring 28 will be reset, thereby driving the proportioning box 10 to move synchronously to reset. In one embodiment, such as Figure 2 and Figure 6 As shown, multiple guide rods 30 are fixedly installed on the upper surface of the support frame 9, and multiple side plates 26 are provided with through holes for the guide rods 30 to move. By setting the guide rods 30, the stability of the side plates 26 and the mixing box 10 during the movement can be effectively improved. In one embodiment, such as Figure 2 and Figure 6 As shown, a first bellows cover 29 is fitted over the damping rod 27. The two ends of the first bellows cover 29 are fixedly connected to the opposite side of the side plate 26 and the support frame 9, respectively. The first bellows cover 29 can effectively protect the damping rod 27 and the return spring 28, thereby effectively extending the service life of the damping rod 27 and the return spring 28. In one embodiment, such as Figures 1-4 As shown, multiple fixed brackets 11 are fixedly installed on the surface of the support frame 9. An inlet cylinder 12 is fixedly installed inside the fixed bracket 11. The bottom of the inlet cylinder 12 is connected to the upper surface of the mixing tank 10 through a second solenoid valve 13 and a hose 14. When it is necessary to quantitatively process different raw materials, simply add different raw materials into different inlet cylinders 12, and then open the second solenoid valve 13 at the bottom of the different inlet cylinders 12. At this time, different raw materials can enter different mixing tanks 10 for quantitative processing. In one embodiment, such as Figure 2 and Figure 5As shown, a rotating rod 21 is rotatably connected to the inner wall of the mixing cylinder 5, and multiple stirring frames 22 are fixedly installed on the outer wall of the rotating rod 21. A first motor 15 is fixedly connected to the upper surface of the mixing cylinder 5. The rotating rod 21 is driven by the first motor 15. When the raw liquid enters the mixing cylinder 5, the first motor 15 is started. At this time, the first motor 15 will drive the rotating rod 21 and the stirring frames 22 to rotate synchronously. During the rotation of the stirring frames 22, different raw liquids can be effectively mixed and stirred, thereby effectively producing the repair liquid and improving the uniformity of the repair liquid. In one embodiment, such as Figures 1-3 As shown, multiple partition positioning plates 3 are fixedly installed on the upper surface of the placement seat 1. The partition positioning plates 3 facilitate the placement of the battery by the staff, so that the device can effectively add repair fluid to the battery. In one embodiment, such as Figure 4 and Figure 7 As shown, an adjusting plate 19 is fixedly installed on the surface of the placement seat 1. A threaded rod 31 is rotatably connected to the inner wall of the adjusting plate 19. A second motor 20 is fixedly connected to the upper surface of the adjusting plate 19. The threaded rod 31 is driven by the second motor 20. A threaded plate 32 is threadedly connected to the outer wall of the threaded rod 31. The surfaces of the adjusting plate 19 and the placement seat 1 are provided with movable grooves for the threaded plate 32 to move. The surface of the threaded plate 32 is fixedly connected to the surface of the lifting plate 4. When it is necessary to add repair fluid to the battery, simply start the second motor 20. At this time, the second motor 20 will drive the threaded rod 31 to rotate synchronously. The threaded plate 32 will move synchronously on the outer wall of the threaded rod 31, driving the lifting plate 4 to move synchronously. The lifting plate 4 will then drive the filling head 8 to move synchronously. When the filling head 8 is inserted into the filling port on the upper surface of the battery, the pump 6 is started. At this time, the pump 6 can effectively transfer the repair fluid to the filling head 8 and then discharge it through the filling head 8. At this time, the battery can be effectively filled with repair fluid. In one embodiment, such as Figure 4 and Figure 7 As shown, a sliding sleeve 33 is fixedly connected to the surface of the threaded plate 32, and the sliding sleeve 33 is slidably connected to the outer wall of the adjusting plate 19. A fixed sleeve 34 is symmetrically installed on the surface of the adjusting plate 19, and a second bellows cover 35 is symmetrically installed on the surface of the sliding sleeve 33. The other end of the second bellows cover 35 is fixedly connected to the surface of the fixed sleeve 34. During the movement of the threaded plate 32, the sliding sleeve 33 will also move synchronously. At this time, the sliding sleeve 33 will stretch or compress the second bellows cover 35 synchronously. Through the setting of the second bellows cover 35, the interior of the adjusting plate 19 can be effectively protected, thereby preventing dust and other impurities in the external environment from entering the adjusting plate 19 and affecting the normal use of the threaded rod 31 and the threaded plate 32. In one embodiment, such as Figures 1-4 As shown, the surface of the placement seat 1 is symmetrically provided with guide grooves, and the inner wall of the guide grooves is symmetrically installed with slide rods 36. The outer wall of each pair of slide rods 36 is slidably connected with sliders 37. The surfaces of the two sliders 37 are fixedly connected to the surface of the lifting plate 4. Through the setting of slide rods 36 and sliders 37, the limiting and guiding function can be effectively played, thereby effectively improving the stability of the lifting plate 4 and the filling head 8 during the movement process.

[0027] In one embodiment, such as Figure 3 As shown, a rubber anti-slip pad 18 is attached to the bottom of the placement base 1. Herringbone anti-slip grooves are evenly spaced on the bottom of the rubber anti-slip pad 18. The rubber anti-slip pad 18 and the herringbone anti-slip grooves can effectively increase the friction between the placement base 1 and the ground, thereby preventing the device from shifting during use and effectively improving the stability of the device during use.

[0028] The above embodiment discloses a precise battery repair fluid filling device. When a battery needs repair fluid filling, simply add different original solutions of the repair fluid into the inlet cylinder 12, and then open the second solenoid valve 13 at the bottom of each inlet cylinder 12. This allows the different original solutions to enter different mixing tanks 10. When the original repair fluid enters the mixing tank 10, its weight causes the mixing tank 10 to shift downwards. This causes the mixing tank 10 to move the mounting sleeve 23 synchronously, which in turn moves the lower pressure frame 24 synchronously. The bottom of the lower pressure frame 24 then contacts the weighing... When the upper surface of sensor 25 is reached, the weighing sensor 25 can be used to weigh and quantify the stock solution in the mixing tank 10. When the weight of the stock solution reaches the specified standard, the weighing sensor 25 will transmit a signal to the controller. The controller will then control the first solenoid valve 16 to open and the corresponding second solenoid valve 13 to close. At this time, the quantified stock solution will enter the mixing cylinder 5. After the stock solution enters the mixing cylinder 5, the first motor 15 will be started. At this time, the first motor 15 will drive the rotating rod 21 and the stirring frame 22 to rotate synchronously. During the rotation of the stirring frame 22, different stock solutions can be effectively mixed and stirred. This allows for the effective production of the repair solution, improving its uniformity, mixing accuracy, and efficiency. It also eliminates the tedious manual measuring, mixing, and repeated density checks, significantly reducing the workload for staff. During the downward movement of the installation sleeve 23, the side plate 26 moves synchronously, simultaneously squeezing the damping rod 27 and the return spring 28. When the original solution in the mixing tank 10 enters the mixing cylinder 5, the return spring 28 resets, thus driving the mixing tank 10 to move synchronously back to its original position. After the repair solution is mixed, the second... Motor 20, at this time, will drive the threaded rod 31 to rotate synchronously, and the threaded plate 32 will move synchronously on the outer wall of the threaded rod 31, driving the lifting plate 4 to move synchronously. The lifting plate 4 will then drive the filling head 8 to move synchronously. When the filling head 8 is inserted into the filling port on the upper surface of the battery, the liquid pump 6 will be started. At this time, the liquid pump 6 can effectively transfer the repair fluid to the filling head 8 and then discharge it through the filling head 8. At this time, the battery can be effectively filled with repair fluid, improving the efficiency and effect of battery repair fluid filling (the weighing sensor 25 is model LCE02 single point type).

[0029] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
