Description

Technical Field

[0001] The utility model relates to the field of lead-acid batteries, in particular to a tin welding wire detection sample preparation device. Background Art

[0002] Lead-acid batteries are a type of "resource recycling type" energy product with high safety, stable electrical performance, low manufacturing cost, wide application fields, and low-cost recycling. Their production is a deep processing and labor-intensive method. The copper terminals and pole columns of lead-acid batteries are welded by solder wires. The detection of the solder wires for copper terminals is an important link to ensure the welding quality and reliability. By detecting the solder wires, it can be ensured that their composition, melting point, etc. meet the requirements, thus ensuring the firmness and conductivity of the welding. Excessive content of impurity elements may affect the performance of the welded joint. In the production of lead-acid batteries, the welding quality is directly related to the reliability and safety of the product. By detecting the solder wires, the risk of failures caused by welding problems can be reduced. The photoelectric direct-reading spectrometer is a rapid quantitative analysis instrument for analyzing the composition of ferrous and non-ferrous metals. In the laboratory, the photoelectric direct-reading spectrometer is used to quickly and quantitatively analyze the composition of the solder wires, so as to judge the impurity composition and proportion of the solder wires. When the photoelectric direct-reading spectrometer is used for detection, the material to be detected needs to be flat and completely cover the detection port of the spectrometer. In the prior art, the experimenter often first intercepts an appropriate length of the sample and tightly curls it into a ball to obtain a prefabricated sample, and then uses a hammer to knock the surface of the prefabricated sample flat to obtain a detection sample, and then performs the detection through the photoelectric direct-reading spectrometer. However, using a hammer to strike the solder wire ball usually requires a very high operating level of the experimenter, and it is very easy to cause inaccurate detection results due to uneven knocking or light leakage, and it is also time-consuming and laborious. Therefore, it is necessary to design a sample preparation tool with simple operation, convenience, and high sample preparation quality. Summary of the Utility Model

[0029] Please refer to Figures 1 to 3 , the embodiment of the present application provides a tin solder wire detection sample preparation device 100, which is characterized in that it includes a base 1, a pressing block 2 and a handle 3. Among them, the base 1 is used to carry a prefabricated tin solder wire sample, the pressing block 2 is arranged above the base 1 and is movably connected to the base 1 through the handle 3. The handle 3 is arranged above the pressing block 2 and is movably connected to the pressing block 2. The handle 3 is rotatably connected to the base 1. The handle 3 is used to drive the pressing block 2 to abut against the upper surface of the prefabricated tin solder wire sample on the base 1 and apply pressure to the prefabricated tin solder wire sample to obtain a target tin solder wire sample.

[0030] The tin solder wire detection sample preparation device 100 provided by the embodiment of the present application drives the pressing block 2 to abut against the upper surface of the prefabricated tin solder wire sample on the base 1 through the handle 3, and applies pressure to the prefabricated tin solder wire sample to obtain a target tin solder wire sample with a flat surface, avoiding manual sample preparation, improving the efficiency of tin solder wire detection sample preparation, improving the uniformity of tin solder wire detection samples, and facilitating detection.

[0031] In a feasible implementation manner, a limiting sleeve 4 is provided on the base 1. The inside of the limiting sleeve 4 is hollow to form a chamber 41. The chamber 41 is used to accommodate the prefabricated tin solder wire sample. And the chamber 41 has an opening vertically upward. The pressing block 2 enters the chamber 41 through the opening to press the prefabricated tin solder wire sample. By setting the limiting sleeve 4, on the one hand, the position of the prefabricated tin solder wire can be fixed, and on the other hand, it can also provide accurate positioning for the pressing block 2 to extrude the prefabricated tin solder wire sample for sample preparation, facilitating the output of the pressure of the pressing block 2.

[0032] In a feasible implementation manner, the base 1 can also replace the limiting sleeve 4 by opening structures such as grooves to play a role in fixing the prefabricated tin solder wire, which will not be elaborated here.

[0033] In a feasible implementation manner, a through groove 42 is provided on the outer wall of the chamber 41 of the limiting sleeve 4. The through groove 42 is used for taking and placing the prefabricated tin solder wire sample. As Figure 4 shown, the prefabricated tin solder wire sample can be that one end of the tin solder wire to be detected is curled into a ball, and the other end remains filamentous for easy holding. The end curled into a ball can be a structure similar to a lollipop. When placing the prefabricated tin solder wire sample into the limiting sleeve 4, the filamentous end can be held, and the end curled into a ball can be placed on the surface of the limiting sleeve 4.

[0034] In a feasible implementation manner, the handle 3 is hingedly connected to the base 1. The hinge connection has the following advantages: Rotation and translation: The hinge allows the two connected parts to rotate relative to each other; Angle adjustment: The hinge can be adjusted to a specific angle to keep the object stable or reach the ideal use position. Extended service life: High-quality hinges can withstand repeated opening and closing actions, reduce wear, and thus extend the service life of the connected components. Easy maintenance: The hinge design facilitates disassembly and reinstallation, making it convenient for cleaning, inspection, or replacement. Safety: Prevent accidental closing: The damping hinge can close slowly to prevent pinching. Stable support: Ensure the stability of the connected components in the open state and prevent accidental collapse. Load-bearing capacity: The hinge can support a large weight and improve the structural stability of the equipment. Save maintenance costs: Durable hinges reduce long-term maintenance and replacement costs.

[0035] Further, the specific manner in which the handle 3 is hingedly connected to the base 1 is as follows: A first hinge hole 11 is provided on the base 1. A second hinge hole 321 is provided on the handle 3. A first hinge shaft 12 passes through the first hinge hole 11 and the second hinge hole 321 to hinge the base 1 and the handle 3.

[0036] In a feasible implementation manner, the handle 3 includes a continuous holding portion 31 and a sliding portion 32. The holding portion 31 is for holding. One end of the sliding portion 32 away from the holding portion 31 is hinged to the base 1. The pressing block 2 is slidably connected to the sliding portion 32.

[0037] In a feasible implementation manner, a chute 322 is provided on the sliding portion 32 along a first direction X. A sliding shaft 323 is provided in the chute 322 along a second direction Y. A third hinge hole 21 is provided on the pressing block 2 along a third direction, and a third hinge shaft 22 is passed through the third hinge shaft 22. Two ends of a connecting rod 5 are respectively hinged to the sliding shaft 323 and the third hinge shaft 22. Wherein, the second direction Y is perpendicular to the first direction X, and the third direction is parallel to the second direction Y.

[0038] In a feasible implementation manner, the included angle α between the upper surface of the holding portion 31 and the upper surface of the sliding portion 32 is 0° - 30°. In this way, when the prefabricated tin solder wire sample is placed in the limiting sleeve 4 in a relaxed state, and when the pressing block 2 abuts against the upper surface of the prefabricated tin solder wire sample, the upper surface of the holding portion 31 is in a horizontal or slightly downwardly inclined state. In this way, it is convenient for the user to hold, convenient for the user to apply a downward pressure to the holding portion 31, convenient for the output of the pressure, and has a labor-saving effect.

[0039] In a feasible implementation manner, the length of the sliding portion 32 is less than the length of the holding portion 31. In this way, when the pressing block 2 is pressed down, as Figure 3 shown, a power F1 is applied to the holding portion 31 of the handle 3 by the hand. After the pressing block 2 presses on the prefabricated solder wire, a resistance F2 is applied to the sliding portion 32 of the handle 3 through the connecting rod 5. Since the handle 3 rotates around the third rotating shaft, the power arm is L1 and the resistance arm is L2. Since F1 * L1 = F2 * L2 and L1 > L2, this structure forms a labor-saving lever, making the force applied by the hand much smaller than the force applied by the pressing block 2 on the surface of the prefabricated solder wire sample. Usually, the strength of the solder wire does not exceed 70 MPa. Assuming the diameter of the pressing block 2 is 30 mm, and the force required for the pressing block 2 to flatten the solder wire is F, then F / (π * 0.015 * 0.015) = 70 * 10 3 Pa, so F = 70 * 10 3*(π * 0.015 * 0.015) = 49.48 N, and this structure is a labor-saving lever. Therefore, the force that the hand needs to provide is much less than 49.48 N. Usually, the strength of a human hand is 101 N. Therefore, the sample preparation work can be easily completed.

[0040] In a feasible implementation manner, the cross-section of the pressing block 2 and the cross-section of the chamber 41 of the limiting sleeve 4 are circular, and the cross-sectional area of the pressing block 2 is slightly smaller than the cross-sectional area of the chamber 41. The pressing block 2 with a circular cross-section can provide a uniform pressure distribution on the contact surface, which helps to avoid local stress concentration and reduce the deformation or damage of the material. A circle has no specific directionality, which means that no matter from which angle the force is applied, the effect is the same. This is particularly useful for applications that require isotropic pressure. Compared with a square or rectangular pressing block 2, the edge of the circular pressing block 2 is smoother, which can reduce edge stress concentration and the risk of crack formation. The circular pressing block 2 can be simply positioned and centered through its axis, which is particularly important especially in applications involving rotation or precise alignment. The manufacture of the circular pressing block 2 usually achieves higher precision more easily than complex shapes, which helps to improve the quality and consistency of the final product. Design flexibility: The circular pressing block 2 can easily fit various-shaped holes or grooves, providing greater design freedom. High material utilization rate: Manufacturing the pressing block 2 with a circular cross-section usually allows for a higher material utilization rate from the raw materials, reducing waste. Strength and rigidity: A circular cross-section generally has higher bending and torsional strength under the same volume, providing better structural rigidity.

[0041] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0042] The above-described embodiments only represent several implementation manners of the present utility model. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the present utility model patent shall be subject to the appended claims.
