Description

Technical Field

[0001] This utility model belongs to the field of lead-acid battery technology, specifically relating to an electrolyte collection device in an adsorption-type glass fiber separator. Background Technology

[0002] In valve-regulated lead-acid batteries, the electrolyte is stored in AGM separators. There is no flowing liquid inside the battery case. During charge-discharge cycles, a concentration difference in the electrolyte within the separator occurs. Due to gravity, the electrolyte concentration is consistently higher at the top of the separator and lower at the bottom. When disassembling and analyzing the battery, it is necessary to measure the sulfuric acid concentration in the electrolyte at the top, middle, and bottom of the separator. Currently, this is done manually, which is difficult and results in uneven sampling.

[0003] Patent application CN110967277A discloses a method for determining the sulfuric acid content and proportion in battery separators and plates. This method involves first soaking the positive and negative plates in pure water and repeatedly washing and squeezing the separators to obtain a filtrate. The plates and separators are then dried under vacuum. The H2SO4 content is calculated by measuring the weight change of the plates and separators before and after drying, and the mass fraction of H2SO4 in the filtrate is also measured to calculate the proportion of H2SO4 in the plates and separators. However, this method involves multiple treatments of the plates and separators. In practice, this often leads to issues such as lead paste peeling off the plates and separator damage, resulting in significant errors in the determination of the H2SO4 content.

[0004] Patent application CN119666654A discloses a method for determining the sulfuric acid concentration of electrolyte stored in the plates or separators of a lead-acid battery. This method first immerses the plates or separators in pure water, and then uses a vacuum to remove residual gas from the micropores within the plates or separators, causing H2SO4 to mix thoroughly with the pure water, resulting in solution 1. Using a measuring device, the mass of the electrolyte in the plates or separators is obtained by calculating the difference between the mass of the plates or separators suspended in pure water and the mass of the pure water mixed with H2SO4 at the bottom. Simultaneously, the mass fraction of H2SO4 in solution 1 is measured, and the mass percentage of H2SO4 in the plates or separators is obtained by calculating the dilution ratio. However, this method does not accurately sample the middle and lower parts of the separator. Utility Model Content

[0005] To address the aforementioned technical problems in the prior art, this utility model provides an electrolyte collection device for an adsorption-type glass fiber separator.

[0006] This invention provides an electrolyte collection device for an adsorption-type glass fiber separator, comprising a separator cutting unit and a separator extrusion unit. The partition cutting unit includes: a first placement platform for placing partitions; a cutter, including at least one, for cutting the partitions; and a first driving mechanism for driving the cutter to cut the partitions into multiple segments along the vertical direction during assembly and use. The partition extrusion unit includes: a second placement platform with pressing holes, the number of which is the same as the number of segments after the partition is cut; a pressing head located above the pressing holes, with a pressing head above each pressing hole; and a second driving mechanism for driving the pressing head to extrude the electrolyte from the partition placed in the pressing hole.

[0007] Preferably, the partition cutting unit includes a first bracket disposed on one side of the first placement platform, and the first driving mechanism includes a first cylinder disposed on the first bracket and driving the cutter to move vertically. The first driving mechanism drives the cutter to move vertically, thereby cutting the partition. The cylinder achieves extreme simplification in structure, cost, and maintenance while ensuring sufficient cutting capacity and production efficiency. Furthermore, the cylinder can operate stably in dusty, humid, or slightly corrosive environments, ensuring high safety.

[0008] Preferably, the partition extrusion unit includes a second bracket disposed on one side of the second placement platform, and the second driving mechanism includes a second cylinder disposed on the second bracket for driving the pressure head to move vertically. The second cylinder drives the pressure head to move vertically downward, thereby squeezing the electrolyte in the partition downward and removing it.

[0009] Preferably, the cutter comprises two spaced-apart blades that cut the separator vertically into three equal sections (top, middle, and bottom) for assembly and use; correspondingly, there are three pressure holes and three pressure heads. This allows for the measurement of sulfuric acid concentration in the electrolyte at the bottom, middle, and bottom of the separator, making it more suitable for the dissection and analysis of lead-acid batteries.

[0010] More preferably, the interval between the two cutters is adjustable, allowing for the selection of specific sections of the partition for collection and measurement of sulfuric acid concentration as needed.

[0011] More preferably, the partition cutting unit includes a mounting guide post for mounting the cutter. The cutter has a mounting hole through which the mounting guide post passes, and the cutter is fixed to the mounting guide post by a positioning screw. The two cutters can move horizontally on the mounting guide post, thereby adjusting the interval between the two cutters.

[0012] Preferably, both the pressing hole and the pressing head are conical, with the bottom surface of the pressing hole having a through hole for electrolyte outflow. The conical shape of both the pressing hole and the pressing head allows for automatic alignment and guidance. As the pressing head is pressed in, the conical surfaces fit tightly together, achieving a smooth transition and uniform distribution of pressure, preventing localized stress damage to the workpiece. The through hole on the bottom surface ensures smooth electrolyte outflow during the extrusion process, avoiding accuracy deviations caused by liquid accumulation and preventing the formation of a sealed pressure chamber, thus ensuring the continuity and stability of the process flow.

[0013] Preferably, the first and second placement platforms use the same platform, with the partition cutting unit and the partition extrusion unit located at opposite ends of this platform. Using the same platform not only saves costs but also facilitates smoother operation of the partition cutting and extrusion processes.

[0014] Compared with the prior art, the present invention has the following beneficial effects: This invention allows for precise sampling of various parts of the lead-acid battery separator to determine the concentration of sulfuric acid in the electrolyte, resulting in more accurate measurement data.

[0021] like Figures 1-5 As shown, this embodiment provides an electrolyte collection device in an adsorption-type glass fiber separator, including a separator cutting unit and a separator extrusion unit.

[0022] The partition cutting unit includes a first placement table 2, a cutter 3, and a first driving mechanism. The first placement table 2 is used to place the partition 1; the cutter 3 includes at least one for cutting the partition 1; the first driving mechanism is used to drive the cutter 3 to cut the partition 1 into multiple segments along the vertical direction during assembly and use.

[0023] The partition cutting unit also includes a first bracket 5 disposed on one side of the first placement platform 2, and a first drive mechanism including a first cylinder 4 disposed on the first bracket 5 and driving the cutter 3 to move vertically. The first drive mechanism drives the cutter 3 to move vertically, thereby cutting the partition 1. The cylinder achieves extreme simplification in structure, cost, and maintenance while ensuring sufficient cutting capacity and production efficiency. Furthermore, the cylinder can work stably in dusty, humid, or slightly corrosive environments, ensuring high safety.

[0024] The partition extrusion unit includes a second placement platform 6, a pressure head 7, and a second driving mechanism. The second placement platform 6 has pressure holes 61, the number of which is consistent with the number of segments after the partition 1 is cut; the pressure head 7 is located above the pressure holes 61, with one pressure head 7 above each pressure hole 61; the second driving mechanism is used to drive the pressure head 7 to extrude the electrolyte from the partition 1 placed in the pressure hole 61.

[0025] Both the pressing hole 61 and the pressing head 7 are conical. The bottom surface of the pressing hole 61 has a through hole for electrolyte to flow out, and a sampling cup 8 can be placed below the through hole to receive the flowing electrolyte. The conical shape of the pressing hole 61 and the pressing head 7 allows for automatic alignment and guidance. As the pressing head 7 is pressed in, the conical surfaces fit tightly together, achieving a smooth transition and uniform distribution of pressure, avoiding damage to the workpiece from localized stress. The through hole on the bottom surface ensures smooth flow of electrolyte during the extrusion process, preventing accuracy deviations caused by liquid accumulation and preventing the formation of a sealed pressure chamber, thus ensuring the continuity and stability of the process flow.

[0026] The partition extrusion unit also includes a second support 10 disposed on one side of the second placement platform 6, and a second drive mechanism including a second cylinder 9 disposed on the second support 10 and driving the pressure head 7 to move vertically. The second cylinder 9 drives the pressure head 7 to move vertically downward, which can squeeze the electrolyte in the partition 1 downward and remove it.

[0027] The first placement table 2 and the second placement table 6 use the same placement table, with the partition cutting unit and the partition extrusion unit located at opposite ends of this placement table. Using the same placement table not only saves costs but also facilitates the smooth operation of the two processes of partition 1 cutting and extrusion.

[0028] To facilitate the dissection and analysis of lead-acid batteries, the cutter 3 includes two spaced-apart blades that cut the separator 1 vertically into three equal sections: upper, middle, and lower. Correspondingly, there are three pressure holes 61 and three pressure heads 7, which allows for the measurement of the concentration of sulfuric acid in the electrolyte at the upper, middle, and lower parts of the separator 1.

[0029] The interval between the two cutters 3 is adjustable, allowing for the selection of specific locations on the partition 1 for sulfuric acid concentration measurement as needed. Specifically, a mounting guide post 51 for mounting the cutters 3 is provided on the first bracket 5 of the partition cutting unit. The cutters 3 have mounting holes through which the mounting guide post 51 passes, and the cutters 3 are fixed to the mounting guide post 51 by positioning screws. The two cutters 3 move horizontally on the mounting guide post 51, thereby adjusting the interval between the two cutters 3.

[0030] The electrolyte collection device in the above-mentioned adsorption-type glass fiber separator is operated as follows: (1) After dissecting the battery, take out the separator 1 to be tested and place it on the first placement platform 2. Adjust the position of the cutter 3 on the mounting guide post 51 so that the cutter 3 is on the three-part line of the separator 1 to be cut. The first cylinder 4 drives the cutter 3 to descend and cut the separator 1 into three sections: upper, middle and lower.

[0031] (2) Place the cut partition 1 on the three pressure holes 61 on the second placement platform 6 respectively. The second cylinder 9 drives the pressure head 7 to descend and squeeze the partition 1 into the pressure hole 61. The sampling cup 8 below the pressure hole 61 collects the electrolyte from each extruded partition until no electrolyte drips down, and the sampling is completed.
