Description

Technical Field

[0001] The utility model relates to the technical field of battery copper wire cleaning, in particular to a copper wire soaking device for batteries. Background Art

[0002] When manufacturing a three-electrode battery, concentrated sulfuric acid is required to soak copper wires to remove oxides or paint coatings on the surface of the copper wires, exposing a clean copper surface for subsequent battery assembly steps or battery tests to proceed smoothly. In the existing process of soaking copper wires in concentrated sulfuric acid, multiple layers of copper foils are usually used as the fixing carriers for the copper wires. Generally, there are four layers of copper foils, and the single-layer copper foil is 5μm. The double-sided tape is cut into strips suitable for the width of the copper wires. Then, one side of the double-sided tape is pasted at an appropriate position on the copper foil. Finally, the copper wires are placed on the copper foil, aligned with the position of the double-sided tape, and gently pressed to make the copper wires in close contact with the double-sided tape. However, using copper foils to fix copper wires has some obvious disadvantages: 1. The copper foils themselves will also be corroded to a certain extent in the concentrated sulfuric acid environment. Although the corrosion rate may be lower than that of the copper wires, long-term soaking may still cause the copper foils to become thinner or deformed, thus affecting their fixing effect; 2. The copper foils may not provide sufficient mechanical strength to firmly fix the copper wires, especially when the copper wires need to withstand greater tension or vibration, which makes the operation difficult. When fixing the copper wires on the copper foils, it is necessary to ensure close contact and good fixation between the two, which may require high operating skills and patience; 3. After soaking, concentrated sulfuric acid or other impurities may remain on the copper foils, and these substances may be difficult to completely remove, increasing the difficulty of the cleaning work. If the copper foils are severely corroded or deformed during the experiment, complex subsequent processing or replacement of new copper foils may be required, increasing the cost and complexity of the experiment; 4. There are safety hazards. If the copper foils are not firmly fixed or the copper wires fall off, it may cause damage to the experimental device or splashing of concentrated sulfuric acid, posing a safety threat to the experimental personnel.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model. It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other arbitrarily.

[0023] Please refer to Figures 1 to 4 A copper wire soaking device for a battery according to an embodiment of the present utility model includes a glass plate 2 and a glass container 1 for containing concentrated sulfuric acid with a first preset volume. The width of the glass plate 2 is less than the diameter of the glass container 1. After the copper wire 3 is wound around its side, the glass plate 2 is fixed inside the glass container 1. The height of the top of the concentrated sulfuric acid is 1-2 cm higher than the height of the bottom of the copper wire 3, so that a part of the copper wire 3 is located inside the concentrated sulfuric acid and another part is located above the concentrated sulfuric acid.

[0024] Here, the copper wire 3 is wound around the side of the glass plate 2, and a first preset volume of concentrated sulfuric acid is placed in the glass container 1. Ensure that when the glass plate 2 is placed in the glass container 1, the height of the top of the concentrated sulfuric acid is 1-2 cm higher than the height of the bottom of the copper wire 3, so that a part of the copper wire 3 is located inside the concentrated sulfuric acid and another part is located above the concentrated sulfuric acid, thereby ensuring that the concentrated sulfuric acid can soak the copper wire 3 located inside the concentrated sulfuric acid to remove the oxides or enamel on the surface of this part of the copper wire 3.

[0025] Specifically, the steps of soaking the copper wire 3 with concentrated sulfuric acid are as follows: 1. Prepare materials: enameled copper wire 3 with an appropriate diameter, such as 20 μm, concentrated sulfuric acid is usually 98.3% by mass fraction, glass container 1, deionized water, alcohol and other cleaning supplies, drying equipment, such as an oven or a hair dryer; 2. Cut the copper wire 3: Cut the enameled copper wire 3 to a certain length according to needs; 3. Fix the copper wire 3: Place the fixed copper wire 3 in the glass container 1 to ensure that the copper wire 3 can stand firmly for subsequent operations; 4. Add concentrated sulfuric acid: Add a certain amount of concentrated sulfuric acid to the glass container 1, and the liquid level should cover the bottom of the copper wire 3 by about 1.0-2.0 cm; Let it stand for corrosion: Let the copper wire 3 stand in the concentrated sulfuric acid for a period of time, generally 2 hours, so that the enamel at the bottom of the copper wire 3 is corroded and removed by the concentrated sulfuric acid, exposing the copper wire 3 inside; Wash the copper wire 3: Take out the copper wire 3 from the concentrated sulfuric acid, first wash it thoroughly with deionized water 3 times to remove the residual sulfuric acid, and then rinse it with alcohol 3 times to further remove the oil and impurities on the surface of the copper wire 3. 5. Dry the copper wire 3: Place the washed copper wire 3 in the drying equipment for drying to ensure that the surface of the copper wire 3 is completely dry.

[0026] Specifically, the following precautions apply: 1. Safety First: When handling concentrated sulfuric acid, wear protective glasses, gloves, and a lab coat, and ensure that the work is done in a well-ventilated environment. 2. Handle with Care: Concentrated sulfuric acid is highly corrosive and oxidizing, and can severely burn the skin and eyes, and even cause fires and explosions. Therefore, extreme caution must be exercised during handling to avoid spills or leaks. 3. Accurate Control: Ensure the amount of concentrated sulfuric acid used and the soaking time are appropriate to avoid excessive corrosion or damage to the copper wire 3. 4. Post-Processing: After handling the concentrated sulfuric acid, clean the lab bench and equipment promptly, pour the waste liquid into the designated waste container, and dispose of it properly according to laboratory regulations.

[0027] Specifically, during the soaking process of the copper wire 3 in concentrated sulfuric acid, securing the copper wire 3 is a crucial step. Improper securing of the copper wire 3 can lead to a series of adverse consequences: 1. Uneven soaking: If the copper wire 3 is not securely secured, it may soak unevenly in the concentrated sulfuric acid. Some areas may not be fully exposed to the concentrated sulfuric acid, preventing effective removal of surface varnish or oxides, thus affecting subsequent test results. 2. Shifting or toppling of the copper wire 3: If the securing method is not secure, the copper wire 3 may shift or topple during the soaking process, or even completely fall out of the concentrated sulfuric acid liquid. This not only leads to soaking failure but also may expose the copper wire 3 to substances other than concentrated sulfuric acid, such as air or water, resulting in unpredictable reactions or contamination. 3. Safety issues: Improper securing of the copper wire 3 can also cause safety issues. For example, if the copper wire 3 suddenly topples during soaking, concentrated sulfuric acid may splash out, causing chemical burns to operators or posing a fire hazard. Furthermore, an unstable copper wire 3 may interfere with the normal operation of experimental equipment, increasing experimental risks. 4. Inaccurate experimental data: Problems such as uneven immersion or displacement of the copper wire 3 may lead to inconsistent performance of the copper wire 3 used in subsequent battery assembly or testing, thereby affecting the accuracy and reliability of the experimental data.

[0028] Specifically, based on the shortcomings of using copper foil as a carrier to fix the copper wire 3, in actual operation, you can try to use other fixing materials or methods, such as using a high-temperature resistant and corrosion-resistant carrier to fix the copper wire 3 to improve the reliability and safety of the experiment. The utility model effectively fixes the copper wire 3 by using a glass plate 2 instead of copper foil.

[0029] Specifically, using the glass plate 2 to fix the copper wire 3 has several significant advantages. These advantages are mainly reflected in the following aspects:

[0030] Chemical stability: Glass is a relatively chemically stable material and does not react with concentrated sulfuric acid. This means that in a concentrated sulfuric acid environment, the glass plate 2 maintains its integrity and is not damaged by corrosion, thus ensuring the safety and reliability of the experiment.

[0031] High temperature resistance: When concentrated sulfuric acid reacts with copper wire 3, a certain amount of heat may be released. Glass has a high melting point and can withstand certain temperature changes without deformation or cracking. Therefore, using glass plate 2 to fix copper wire 3 can ensure that the fixing device will not be damaged due to temperature rise during the experiment.

[0032] Easy to clean: If sulfuric acid splashes onto glass plate 2 during the experiment, since the glass surface is smooth and not easily adsorbent to liquids, it can be easily cleaned with water or other appropriate cleaning agents. This helps to maintain the cleanliness of the experimental environment and the accuracy of experimental results.

[0033] Simple operation: Glass plate 2 usually has a flat surface and appropriate hardness, making it an ideal choice for fixing copper wire 3. The experimenter can easily place copper wire 3 on glass plate 2 and use appropriate tools, such as double-sided tape, to fix it. This simple operation method helps to save experimental time and improve experimental efficiency.

[0034] Convenient observation: Since glass is transparent, using glass plate 2 to fix copper wire 3 also allows the experimenter to conveniently observe the reaction process. The experimenter can clearly see the changes of copper wire 3 in concentrated sulfuric acid, thus more accurately judging the reaction progress and results.

[0035] In summary, using glass plate 2 to fix copper wire 3 in the concentrated sulfuric acid immersion experiment has the advantages of good chemical stability, high temperature resistance, easy to clean, simple operation, and convenient observation. These advantages make glass plate 2 an ideal choice for fixing copper wire 3 in the experiment.

[0036] Cost saving: In the experiment of immersing copper wire 3 in concentrated sulfuric acid, using glass plate 2 to fix copper wire 3 not only has operational convenience and clear experimental observation, but also glass plate 2 as a fixing tool has the advantage of being reusable, which is of great significance for cost saving, avoiding waste and environmental pollution.

[0037] Environmentally friendly: Reusing glass plate 2 also helps to reduce waste generation and environmental pollution. If disposable fixing tools are used for each experiment, these tools are often discarded after use and become solid waste. As a reusable tool, glass plate 2 can significantly reduce the generation of such disposable waste, further reducing the negative impact of the laboratory on the environment and achieving the sustainable development of the laboratory, which is beneficial to environmental protection. Therefore, in the experiment of immersing copper wire 3 in concentrated sulfuric acid, using glass plate 2 to fix copper wire 3 and paying attention to its reusability not only meets the actual needs of experimental operations, but also is an important manifestation of saving resources and protecting the environment.

[0038] The glass container 1 can be a cylindrical container or a cuboid container.

[0039] Specifically, when the glass container 1 is a cylindrical container, the length direction of the glass plate 2 is vertically arranged, the width direction of the glass plate 2 is parallel to the bottom surface of the glass container 1, and the width of the glass plate 2 is less than the diameter of the bottom surface of the glass container 1, so as to facilitate inserting the glass plate 2 into the inside of the glass container 1; when the glass container 1 is a cuboid container, the length direction of the glass plate 2 is vertically arranged, the width direction of the glass plate 2 is parallel to the bottom surface of the glass container 1, and the width of the glass plate 2 is less than the length of the glass container 1, so as to facilitate inserting the glass plate 2 into the inside of the glass container 1. If the width of the glass container 1 is more than twice the thickness of the glass plate 2, multiple glass plates 2 can be placed in the glass container 1 at the same time, and multiple copper wires 3 can be soaked simultaneously.

[0040] The bottom end of the glass plate 2 can abut against the bottom end inside the glass container 1, and the axis of the glass plate 2 coincides with or is parallel to the vertical axis of the glass container 1.

[0041] Specifically, the plane where the glass plate 2 is located is perpendicular to the bottom surface of the glass container 1.

[0042] The glass plate 2 includes a first base body 21 for winding and fixing the copper wire 3, and four limiting blocks 22 for respectively limiting the left end and the right end of the copper wire 3. The four limiting blocks 22 are respectively arranged at the four corners of the first base body 21. Two limiting blocks 22 protrude from the top end of the first base body 21, and the other two limiting blocks 22 protrude from the bottom end of the first base body 21.

[0043] Specifically, the first base body 21 is vertically arranged inside the glass container 1. The length direction of the first base body 21 is perpendicular to the bottom surface of the glass container 1, and the width direction is parallel to the bottom surface of the glass container 1. The copper wire 3 is wound and fixed on the first base body 21 along the length direction of the first base body 21. Two limiting blocks 22 are arranged at the left and right ends of the top of the first base body 21, and two limiting blocks 22 are arranged at the left and right ends of the bottom of the first base body 21. Then, the upper and lower two limiting blocks 22 on the left side respectively limit the left end of the copper wire 3, and the upper and lower two limiting blocks 22 on the right side respectively limit the right end of the copper wire 3. At the same time, the two limiting blocks 22 at the bottom end of the first base body 21 can prevent the bottom end of the copper wire 3 from directly contacting the bottom end of the glass container 1, thereby avoiding uneven soaking of the bottom end of the copper wire 3.

[0044] The thickness of the glass plate 2 can be 2 - 3 mm.

[0045] The length of the glass plate 2 can be 195 - 205 mm, the width of the glass plate 2 is 95 - 105 mm, and the length of the limiting block 22 is 0.5 - 1.5 mm.

[0046] Specifically, the bottom of the glass plate 2 can be in close contact with the bottom of the glass container 1, so as to ensure the effective utilization of the concentrated sulfuric acid in which the copper wire 3 is immersed. The glass plate 2 should have a certain thickness, and the thickness of the glass plate 2 is 2-3 mm. If the thickness of the glass plate 2 is too small, there may be a risk that the copper wire 3 is cut by the two ends of the glass plate 2 during the winding process. A limiting block 22 is respectively arranged at the four corners of the upper, lower, left and right of the first substrate 21. The length of the glass plate 2 can be 200 mm, the width of the glass plate 2 can be 100 mm, and the length of the limiting block 22 can be 1 mm, so as to leave a groove with a depth of 1 mm at both ends of the glass plate 2 respectively. The functions of the groove are as follows: 1. It is convenient for the copper wire 3 to be wound, and it can ensure that the copper wire 3 will not break away from the glass plate 2 during the winding and fixing process of the copper wire 3 on the glass plate 2 and during the process of the copper wire 3 being immersed in the concentrated sulfuric acid; 2. It can prevent the bottom end (the end immersed in the concentrated sulfuric acid) of the copper wire 3 from directly contacting the bottom end of the glass container 1, so as to avoid uneven immersion of the bottom end of the copper wire 3.

[0047] As a copper wire immersion device for a battery in this embodiment, it may further include a double-sided tape 4. One side of the double-sided tape 4 is adhered to the part of the glass plate 2 above the concentrated sulfuric acid, and the other side is adhered to the part of the copper wire 3 above the concentrated sulfuric acid.

[0048] Specifically, the first substrate 21 is arranged vertically, and the copper wire 3 is wound and fixed on the first substrate 21 along the length direction of the first substrate 21. The width direction of the first substrate 21 can be parallel to the bottom surface of the glass container 1. One side of the double-sided tape 4 is adhered to the part of the glass plate 2 above the concentrated sulfuric acid, and the other side is adhered to the part of the copper wire 3 above the concentrated sulfuric acid. The axis of the double-sided tape 4 can be parallel to the width direction of the first substrate 21. One side of the double-sided tape 4 is first pasted on the glass plate 2, that is, the inner side of the double-sided tape 4 is adhered to the glass plate 2. Since the copper wire 3 is wound on the glass plate 2, both large surfaces of the glass plate 2 need to be pasted with the double-sided tape 4; the white protective tape on the outer side of the double-sided tape 4 is removed to expose the other side of the double-sided tape 4, that is, the outer side of the double-sided tape 4 is exposed; the copper wire 3 is wound around the other side of the double-sided tape 4 to fix the copper wire 3; after the copper wire 3 is wound, the white protective tape of the double-sided tape 4 is pasted again at the corresponding position where the double-sided tape 4 is pasted.

[0049] Specifically, the first substrate 21 includes a first side and a second side disposed opposite to each other, a third side respectively connected to one end of the first side and one end of the second side, and a fourth side respectively connected to the other end of the first side and the other end of the second side. The first side is parallel to the second side, the third side is parallel to the fourth side, the third side is perpendicular to the first side. The areas of the first side and the second side are larger, and the areas of the third side and the fourth side are smaller. The copper wire 3 is wound around the first side, the second side, the third side, and the fourth side respectively. The part of the copper wire 3 close to the first side of the first substrate 21 is the fifth side, and the part close to the second side of the first substrate 21 is the sixth side. One side of a double-sided tape 4 can be adhered to the first side. Align the position of the double-sided tape 4 and the fifth side of the copper wire 3, and gently press to make the other side of the double-sided tape 4 adhered to the fifth side; one side of another double-sided tape 4 can be adhered to the second side. Align the position of the double-sided tape 4 and the sixth side of the copper wire 3, and gently press to make the other side of the double-sided tape 4 adhered to the sixth side.

[0050] As a copper wire soaking device for a battery in this embodiment, it may further include two limiting blocks 22 fixed to one end respectively and located above, and a fixing member 5 fixed to the outer side wall of the glass container 1 at the other end.

[0051] The fixing member 5 may include a connecting plate 54 fixed to the two limiting blocks 22 located above the first substrate 21, a first mounting through hole penetrating through the connecting plate 54, a support screw 51 lapped on the top end of the glass container 1, and two first fastening nuts 52 respectively disposed on both sides of the connecting plate 54. The middle part of the support screw 51 is fixedly connected to the first mounting through hole. The two ends of the support screw 51 respectively protrude outside the glass container 1. The two first fastening nuts 52 are respectively screwed onto the two parts of the support screw 51 protruding outside the glass container 1, and the two first fastening nuts 52 respectively abut against the outer side wall of the glass container 1.

[0052] Specifically, the two ends of the support screw 51 are respectively lapped on the top end of the glass container 1. The two ends of the support screw 51 respectively protrude outside the glass container 1. The two first fastening nuts 52 are respectively screwed onto the two parts of the support screw 51 protruding outside the glass container 1. Rotate the first fastening nuts 52 to make the first fastening nuts 52 abut against the outer side wall of the glass container 1. The two first fastening nuts 52 respectively abut against the outer side wall of the glass container 1, thereby fixedly connecting the support screw 51 and the glass container 1, ensuring that the glass plate 2 is stably and vertically arranged inside the glass container 1, thereby stably placing the copper wire 3 in concentrated sulfuric acid. After the copper wire 3 is soaked, rotate the two first fastening nuts 52 respectively to make the two first fastening nuts 52 respectively away from the glass container 1, and take the support screw 51, thereby the glass plate 2 can be taken.

[0053] The fixing member 5 may further include two second fastening nuts 53 respectively arranged on both sides of the connecting plate 54. The two second fastening nuts 53 are respectively screwed onto two portions of the supporting screw rod 51 above the glass container 1, and the two second fastening nuts 53 respectively abut against both side surfaces of the connecting plate 54.

[0054] Specifically, through the two second fastening nuts 53, the supporting screw rod 51 is detachably and fixedly connected to the glass plate 2. By rotating the two second fastening nuts 53 to adjust the position of the supporting screw rod 51 passing through the first mounting through hole, the vertical center line of the supporting screw rod 51 can be adjusted to coincide with the vertical axis of the glass plate 2. The horizontal axis of the supporting screw rod 51 is perpendicular to the vertical axis of the glass plate 2, and the lengths of the portions of the supporting screw rod 51 on the left and right sides of the glass plate 2 are equal.

[0055] Specifically, the glass container 1 is a cylindrical container. The horizontal axis of the glass plate 2 may coincide with a straight line where a diameter of the bottom of the glass container 1 is located, so that the glass plate 2 is arranged at the middle position inside the glass container 1. The horizontal axis of the supporting screw rod 51 may be parallel to another diameter of the bottom of the glass container 1. The two first fastening nuts 52 respectively abut against the top of the outer side wall of the glass container 1. One side of the first fastening nut 52 abutting against the outer side wall of the glass container 1 may be tangent to the outer side wall of the glass container 1. The glass container 1 is a cuboid container. The horizontal axis of the glass plate 2 may be parallel to the length direction of the bottom surface of the glass container 1. If the width of the glass container 1 is more than twice the thickness of the glass plate 2, multiple glass plates 2 can be placed inside the glass container 1 at the same time, and multiple copper wires 3 can be soaked simultaneously. The multiple glass plates 2 are arranged in parallel. A connecting plate 54 is connected to each glass plate 2. The multiple glass plates 2 share one supporting screw rod 51 and two first fastening nuts 52. The horizontal axis of the supporting screw rod 51 may be parallel to the width direction of the bottom surface of the glass container 1. One end of the supporting screw rod 51 is arranged on one side of the glass container 1, and the other end of the supporting screw rod 51 sequentially passes through the first mounting through holes on the multiple connecting plates 54 and protrudes on the other side of the glass container 1. The two first fastening nuts 52 respectively abut against the top of the outer side wall of the glass container 1. The supporting screw rod 51 and the connecting plate 54 connected to one glass plate 2 are detachably and fixedly connected through the two second fastening nuts 53.
