Description

Technical Field

[0001] This utility model relates to the field of battery energy technology, and in particular to a tooling for detecting the casting and welding height of lead-acid batteries. Background Technology

[0002] In the manufacturing process of lead-acid batteries, the precise control of the busbar casting height is directly related to the battery's sealing performance and electrical safety. Currently, the traditional testing method commonly used in the industry requires removing the cast-welded electrode assembly from the battery case as a whole, and having operators manually measure the busbar at multiple points using vernier calipers.

[0003] However, this method has the following drawbacks in practical use: 1. Single-piece inspection takes several minutes and is cumbersome and labor-intensive; 2. Manual readings are easily affected by perspective errors and the randomness of measurement points, resulting in a systematic deviation of more than ±0.2mm, while the industry technical requirement for tolerance is only ±0.5mm, and insufficient accuracy can easily lead to quality control failure; 3. Frequent insertion and removal of electrode groups can easily cause structural damage such as separator tearing, electrode deformation, or poor soldering, thus increasing the rework and scrap rate. Therefore, there is an urgent need to develop a testing fixture that combines high efficiency, low cost, and non-destructive characteristics. Utility Model Content

[0004] In view of the above situation and in order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a method for detecting the welding height of lead-acid batteries, which effectively solves the problem of inconvenient detection of the busbar height of existing lead-acid batteries.

[0005] The technical solution is that the present invention includes a T-shaped stainless steel plate body, which is composed of a vertically arranged measuring beam and a horizontally arranged positioning beam. The connection between the upper left and right sides of the measuring beam and the positioning beam is distributed in a stepped manner. The plane connecting the left end of the positioning beam and the measuring beam is divided into a stepped surface by the first positioning point, the second positioning point, the third positioning point, and the fourth positioning point. The plane connecting the right end of the positioning beam and the measuring beam is divided into a stepped surface by the fifth positioning point, the sixth positioning point, the seventh positioning point, and the eighth positioning point.

[0006] Preferably, the distance between the first and second positioning points is 6.01 cm, the distance between the second and third positioning points is 1.15 cm, the distance between the third and fourth positioning points is 2 cm, the distance between the fifth and sixth positioning points is 6.04 cm, the distance between the sixth and seventh positioning points is 0.97 cm, and the distance between the seventh and eighth positioning points is 2.16 cm.

[0007] Preferably, the thickness of the positioning beam is 1 / 3 to 1 / 2 of the width of the measuring beam, and the two ends of the positioning beam extend symmetrically out of the two sides of the measuring beam, with the extension length being 0.8-1.2 times the width of the measuring beam.

[0008] Preferably, the surface of the stainless steel plate body is hardened to a hardness ≥ HRC40.

[0009] Preferably, the connection between the measuring beam and the positioning beam adopts a circular arc transition with a transition radius R = 2-3 mm.

[0010] Preferably, red markers are provided on all eight positioning points from the first to the eighth.

[0011] Compared with the existing technology, the beneficial effects of this utility model are: through the innovative design of the T-shaped stainless steel plate body, the vertically set measuring beam and the horizontally set positioning beam are integrated into a stepped detection structure. Combined with the red marking point and the arc transition structure, the problems of low measurement efficiency, battery damage and high misjudgment rate of traditional manual vernier calipers are completely solved.

Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the implementations of the base model disclosed below.

[0016] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0017] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0018] Depend on Figure 1The invention includes a T-shaped stainless steel plate body, which is composed of a vertically arranged measuring beam 1 and a horizontally arranged positioning beam 2. The upper left and right sides of the measuring beam 1 are connected to the positioning beam 2 in a stepped manner. The plane connecting the left end of the positioning beam 2 to the measuring beam 1 is divided into a stepped surface by the first positioning point 3, the second positioning point 4, the third positioning point 5, and the fourth positioning point 6. The plane connecting the right end of the positioning beam 2 to the measuring beam 1 is divided into a stepped surface by the fifth positioning point 7, the sixth positioning point 8, the seventh positioning point 9, and the eighth positioning point 10.

[0019] For ease of measurement, the distance between the first positioning point 3 and the second positioning point 4 is 6.01 cm, the distance between the second positioning point 4 and the third positioning point 5 is 1.15 cm, the distance between the third positioning point 5 and the fourth positioning point 6 is 2 cm, the distance between the fifth positioning point 7 and the sixth positioning point 8 is 6.04 cm, the distance between the sixth positioning point 8 and the seventh positioning point 9 is 0.97 cm, and the distance between the seventh positioning point 9 and the eighth positioning point 10 is 2.16 cm.

[0020] For structural strength, the thickness of the positioning beam 2 is 1 / 3 to 1 / 2 of the width of the measuring beam 1, and the two ends of the positioning beam 2 extend symmetrically from the two sides of the measuring beam 1, with the extension length being 0.8-1.2 times the width of the measuring beam 1.

[0021] For ease of use, the surface of the stainless steel plate is hardened to a hardness ≥ HRC40.

[0022] For ease of use, the connection between the measuring beam 1 and the positioning beam 2 is made with a circular arc transition, with a transition radius R = 2-3 mm.

[0023] For easy identification, red markings are provided on all of the above-mentioned positioning points 1 through 8.

[0024] When using this utility model, the upper limit of the height is first tested: the tooling positioning beam 2 is placed horizontally on the upper edge of the battery compartment, and the measuring beam 1 is inserted vertically into the compartment, so that the short handle at the bottom of the positioning beam 2 is close to the outer wall of the compartment. The position of the tooling is adjusted so that the third positioning point 5 (located on the left stepped surface) is precisely aligned with the edge of the upper port of the battery compartment. At this time, the positional relationship between the top of the busbar and the left stepped surface is observed. If the busbar can simultaneously contact the connecting plane formed by the first positioning point 3 and the second positioning point 4 (distance 6.01cm), it indicates that the casting height does not exceed the upper limit (≤6.01 cm) and is judged to be qualified; if the busbar is higher than the plane, it is judged to be out of tolerance.

[0025] Subsequently, perform the lower limit height detection: Keep the positioning beam 2 horizontally close to the trough body, and move the tooling to align the 7th positioning point 9 (located on the right stepped surface) with the edge of the upper port of the battery trough. Observe the relationship between the top of the bus bar and the right stepped surface - if the bus bar cannot contact the connection plane formed by the 5th positioning point 7 and the 6th positioning point 8 (spacing 6.04 cm), it indicates that the casting and welding height is not lower than the lower limit (≥6.04 cm), and it is judged as qualified; if the bus bar contacts or is lower than this plane, it is judged as insufficient.

[0026] During the whole detection process, it is necessary to ensure that the tooling is perpendicular to the battery trough body (using the arc transition structure for auxiliary positioning), and the operation force should be gentle to avoid deformation. After detection, clean the tooling, and regularly calibrate the key dimensions (such as the tolerance of ±0.03 cm for the spacing of 1.15 cm between the 2nd and 3rd positioning points 5, the spacing of 0.97 cm between the 6th and 7th positioning points 9, etc.).

[0027] Compared with the prior art, the beneficial effects of the present utility model are as follows: Through the innovative design of the T-shaped stainless steel plate body, the vertically arranged measuring beam and the horizontally arranged positioning beam are integrated into a stepped detection structure. Combining the red marking points and the arc transition structure, it completely solves the problems of low measurement efficiency, battery damage, and high misjudgment rate of traditional manual vernier calipers. This structure is simple, novel in concept, convenient to use, and has strong practicability.

[0028] It should be noted that according to the needs of implementation, each component described in the embodiments of the present utility model can be split into more components, or two or more components or parts of components can be combined into new components to achieve the purpose of the embodiments of the present utility model.

[0029] The above embodiments only represent several implementation manners of the present utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the patent of the present utility model. It should be pointed out 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 patent of the present utility model should be subject to the appended claims.
