Description

Technical Field

[0001] This utility model relates to the field of lead-acid battery technology, and more specifically to an auxiliary measuring tool for the roughness of perforated mesh grids used in lead-acid batteries. Background Technology

[0002] In the production of lead-acid batteries, perforated grids, as an important electrode material, are widely used due to their advantages such as high production efficiency, high degree of automation, and low production cost. Perforated grids are manufactured by producing continuous lead strips from lead ingots using the "lead strip continuous casting and rolling" technology, and then using "continuous grid punching technology." This process not only improves production efficiency but also reduces production costs, making perforated grids an indispensable part of lead-acid battery production.

[0003] However, in practical use, it has been found that the low surface roughness of the lead strip results in poor bonding between the perforated grid and the lead paste. This poor bonding directly affects the battery's charge acceptance and cycle performance, thus limiting the overall performance of the lead-acid battery. To solve this problem, most manufacturers roughen the perforated grid to increase its surface roughness and improve the bonding with the lead paste.

[0004] However, in actual production, to ensure the grid roughness achieves the desired effect, multiple measurements of the grid are required. Due to the thinness of the grid frame, traditional roughness testers face difficulties in positioning and measurement, hindering rapid and accurate measurement. This not only increases production costs but also affects production efficiency. Therefore, there is an urgent need for an auxiliary measuring fixture to achieve rapid and accurate positioning and measurement of the roughness tester, thereby improving production efficiency, reducing production costs, and ensuring the overall performance of lead-acid batteries.

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0028] Due to the thinness of the mesh frame, positioning and measurement with roughness instruments are relatively difficult, making it hard to achieve fast and accurate measurements. This not only increases production costs but also affects production efficiency. Therefore, this invention provides an auxiliary tooling for measuring the roughness of perforated mesh for lead-acid batteries, enabling rapid and accurate positioning and measurement with roughness instruments, thereby improving production efficiency, reducing production costs, and ensuring the overall performance of lead-acid batteries.

[0029] For the technical solution of this utility model, please refer to the appendix. Figure 1-5 ,include:

[0030] The contact portion 1, which may consist of at least two parts, can be strip-shaped, block-shaped, etc. In the specific embodiment shown in the accompanying drawings, the contact portions are two elongated strips; in other embodiments, there may be more than two. The inner sidewall of the contact portion 1 is tightly fitted to the outer frame of the mesh, ensuring that the tooling is perpendicular to the direction of the outer frame of the mesh and avoiding positioning deviation. At least one of the contact portions 1 has a positioning angle 2 near the outer frame of the mesh. The shape of the positioning angle 2 matches the shape of the rounded corner 10 of the outer frame of the mesh and is tightly fitted, further ensuring positioning accuracy. Alternatively, both contact portions 1 may have a positioning angle 2.

[0031] A longitudinally moving part is located on the contact part 1, and at least a portion of its structure is movable along the direction perpendicular to the outer edge of the grid (X direction); a transversely moving part is located on the longitudinally moving part, and at least a portion of its structure is movable along the direction parallel to the outer edge of the grid (Y direction).

[0032] The X and Y directions are given relative to the view direction for ease of understanding and should not be construed as limiting this application. The X direction serves as a reference for the direction of the outer border of the vertical grid, and the Y direction serves as a reference for the direction of the outer border of the row grid.

[0033] The measuring frame 6 has an internal space for installing instruments and a measuring port 8 at its bottom. The measuring frame 6 moves with the longitudinal and lateral moving parts to complete multi-point measurement of the grid.

[0034] The above solution enables rapid positioning of the grid through the contact part and positioning angle, and allows for multi-point measurement of the grid through longitudinal and lateral movement, which greatly reduces measurement time and improves production efficiency.

[0035] In the description of this utility model, it should be understood that the terms "upper", "lower", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0036] The longitudinal moving rod 4 and the longitudinal linear bearing 3 cooperate to form a longitudinal moving part, and each contact part 1 has at least two longitudinal linear bearings 3 at its top. In a specific embodiment of this utility model, there are two longitudinal linear bearings 3, which can be adjusted according to the number of contact parts 1 in other embodiments. Each longitudinal linear bearing 3 is correspondingly fitted with a longitudinal moving rod 4 that can move along the direction of the outer frame of the vertical grid.

[0037] A transverse linear bearing 5 is provided, and the transverse moving rod 41 and the positioning ring 7 form a transverse moving part. Specifically, each of the longitudinal moving rods 4 has a transverse linear bearing 5, which can move along the direction of the vertical outer frame of the grid following the longitudinal moving rod 4. This can be understood as the transverse linear bearing 5 being externally fixed to the longitudinal moving rod 4. See [reference needed]. Figure 1 The length of the longitudinal moving rod 4 is not fully shown, but its length should be sufficient to meet the measurement requirements. The transverse linear bearing 5 connects the two transverse moving rods 41 of the measuring frame, allowing the measuring frame to move in a direction parallel to the outer edge of the grid. This means the transverse moving rod 41 can move in a direction parallel to the outer edge of the grid, simultaneously measuring the roughness of the inner and outer grid edges. Each transverse linear bearing 5 has a reserved positioning hole facing the measuring frame 6, and each transverse moving rod 41 has a positioning ring 7 corresponding to the positioning hole. The two positioning rings 7 can slide on the transverse moving rods on both sides of the measuring frame. During measurement, the corresponding positioning rings 7 can be installed in the positioning holes to form a tight fit, ensuring accurate positioning of the transverse moving rod 41 and the transverse linear bearing 5 during the measurement process.

[0038] The longitudinal linear bearing enables the longitudinal moving rod and the measuring frame to move in a direction perpendicular to the outer frame of the grid (X direction), thereby enabling multi-point measurement of the roughness of the inner and outer grid frames.

[0039] The transverse linear bearing enables the transverse moving rod and the measuring frame to move in a direction parallel to the outer frame of the grid (Y direction), while simultaneously measuring the roughness of the inner and outer grid frames.

[0040] The positioning ring is located on the transverse moving rods on both sides of the measuring frame. When the positioning ring moves to the left or right and reaches its end, it can form a tight fit with the reserved positioning hole on the outer frame of the transverse linear bearing, ensuring the accuracy of positioning during the measurement process.

[0041] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "connection", "joining", "fixing", etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0042] In this embodiment of the invention, the top of the measuring frame 6 is open to facilitate the insertion of instruments, and it has a reading window 9 on the operating side for easy data reading. A reinforcing plate 11 is provided at the bottom facing the measuring port 8 to enhance the support strength of the bottom of the measuring frame.

[0043] The measuring frame 6 holds the measuring instrument, and its height is higher than 1 / 3 of the instrument's height. The bottom of the measuring frame 6 is 1-2mm higher than the grid surface to ensure measurement accuracy and equipment safety.

[0044] See appendix Figure 5 During measurement, a 1-meter-long grid can be laid flat on the worktable. Place the fixture on both sides of the grid, adjust the positioning angle on the contact part to align with the rounded corners of the grid's outer frame, and ensure that the sidewall of the contact part fits tightly against the outer frame of the grid. The positioning ring engages with the positioning hole on the transverse linear bearing, and the roughness instrument is placed inside the measuring frame.

[0045] According to the measurement requirements, move the longitudinal moving rod to change the position of the measuring frame in the X direction, and move the lateral moving rod to change the position of the measuring frame in the Y direction. Measure the measuring points, and repeat the above steps to complete the multi-point measurement of the grid.

[0046] This invention achieves basic positioning of the fixture and the mesh grid through the tight combination of the positioning angle and the rounded corners of the outer frame; it achieves multi-point longitudinal measurement of the inner and outer mesh grid edges through the longitudinal movement of the measuring frame; and it achieves roughness measurement of the inner and outer edges through the lateral and longitudinal movement of the measuring frame. This fixture enables rapid and accurate positioning and measurement of the roughness meter, reducing human error in measurement and improving product reliability.
