Description

Technical Field

[0001] This invention relates to the field of lead-acid battery technology, and in particular to a lead-acid battery terminal milling device. Background Technology

[0002] After a period of use, lead-acid batteries gradually develop white acidic substances on their positive and negative terminals and connecting wires. In severe cases, leakage occurs at the terminals, and the base of the terminals may be burned or corroded. This is commonly referred to in the industry as acid creep or leakage. To address this issue, the common methods used in the market for lead-acid battery terminals are to increase the acid creep path at the battery terminals and to use rubber sealing rings for sealing.

[0003] For typical welded batteries, several anti-acid-creep rings are machined on a lathe before the lead terminals are welded to the battery body. The welding process requires a high level of skill from the welders, and the quality of batteries welded by different workers varies greatly. Furthermore, the welding efficiency is low and the cost is high. Therefore, it has been gradually replaced by casting welding in current development.

[0004] For cast-welded batteries where copper terminals are embedded in the terminals via gravity casting, the anti-acid creep ring cannot be cast in place due to demolding requirements, necessitating post-casting machining. For small batteries with a single groove adjacent to the copper terminal, milling is typically done manually using a specialized hollow drill, resulting in poor milling quality, low efficiency, and high labor intensity. Hollow drills cannot be used for large batteries with numerous anti-acid creep grooves, limiting the development of cast-welded batteries. Furthermore, after casting, the terminal head contains embedded copper terminals for customer wiring; when milling the anti-acid creep grooves, the cutting tool must avoid the copper terminals to prevent scratches leading to defects or scrap. During machining, milling requires complete removal of the oxide layer from the terminal surface, and the milled lead slag must be safely removed, strictly preventing it from falling into the battery separator paper.

[0005] Therefore, it is necessary to design a lead-acid battery terminal milling machine to overcome the above problems. Summary of the Invention

It has a simple structure, is easy to operate, and can be used for terminal milling operations of various lead-acid batteries.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0037] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0038] like Figures 1 to 4 As shown, the lead-acid battery terminal milling equipment provided in this embodiment includes: a frame 2, a conveying mechanism 3, a positioning mechanism 4, a flipping mechanism 5, a clamping mechanism 6, and a milling mechanism 7.

[0039] The conveying mechanism 3 is mounted on the frame 2 and is used to convey the lead-acid battery 1 placed on it. The positioning mechanism 4 is located on one side of the conveying mechanism 3 and is used to position the lead-acid battery 1, ensuring it remains in a designated position. Specifically, the positioning mechanism 4 includes a positioning cylinder 41 and a positioning rod 42. The positioning cylinder 41 is movably and adjustably mounted on one side of the conveying mechanism 3 along the conveying direction, and the positioning rod 42 is located at the movable end of the positioning cylinder 41 facing upwards from the conveying mechanism 3. When positioning the lead-acid battery 1 is required, the positioning cylinder 41 is activated, and the positioning rod 42 extends to block the lead-acid battery 1, preventing it from continuing to move on the conveying mechanism 3.

[0040] Meanwhile, the flipping mechanism 5 includes a flipping motor 51, a flipping shaft 52, and a flipping frame 53. The flipping shaft 52 is rotatably mounted on the frame 2, and the flipping motor 51 drives and connects to the flipping shaft 52. The flipping frame 53 is mounted on the flipping shaft 52. A clamping mechanism 6 is provided on the flipping mechanism 5 for clamping the lead-acid battery 1. The clamping mechanism 6 includes a limiting seat 61, a clamping seat 62, and a clamping cylinder 63. The limiting seat 61 and the clamping cylinder 63 are mounted on the flipping frame 53. The clamping cylinder 63 drives and connects to the clamping seat 62, driving the clamping seat 62 to move towards and away from the limiting seat 61. When the flipping frame 53 rotates above the conveying mechanism 3, the limiting seat 61 and the clamping seat 62 are located on opposite sides of the lead-acid battery 1.

[0041] When the positioning mechanism 4 restricts the lead-acid battery 1 on the positioning conveying mechanism 3 so that it cannot continue to move on it, the flipping motor 51 is started, so that the flipping frame 53 flips above the conveying mechanism 3. At this time, the limiting seat 61 and the clamping seat 62 are located on opposite sides of the lead-acid battery 1. The clamping cylinder 63 is started, and the clamping seat 62 clamps the lead-acid battery 1 on the limiting seat 61. When the flipping frame 53 continues to flip, the lead-acid battery 1 will flip with the flipping frame 53.

[0042] To better protect the lead-acid battery 1, a protective pad 64 is provided on the side of the limiting seat 61 and clamping seat 62 where the lead-acid battery 1 is clamped. In addition, to accommodate lead-acid batteries 1 of various sizes, the limiting seat 61 and the clamping cylinder 63 are both adjustablely mounted on the flipping frame 53, which can adjust the position of the clamping mechanism 6 according to the actual processing needs, better clamp and fix the lead-acid battery 1, and prepare for the subsequent milling of the terminal post 11.

[0043] like Figures 1 to 4 As shown, the milling mechanism 7 is for upward milling operations. It is mounted on the frame 2 and located on the side of the flipping shaft 52 away from the conveying mechanism 3. When the flipping frame 53 rotates to above the milling mechanism 7, the milling cutter of the milling mechanism 7 corresponds to the terminal post 11 at the bottom of the lead-acid battery 1 clamped by the clamping mechanism 6.

[0044] In this embodiment, the milling mechanism 7 includes a mounting base 71 and milling components 72 mounted on the mounting base 71. The mounting base 71 is mounted on the frame 2 and can be moved up and down via an adjusting cylinder 73. The adjusting cylinder 73 can adjust the height position of the milling components 72, facilitating the milling components 72 to mill the terminals 11 at the bottom of the flipped lead-acid battery 1. For processing efficiency, the number of milling components 72 on the mounting base 71 corresponds to the number of terminals 11 on the lead-acid battery 1 to be milled. In this embodiment, two milling components 72 are used to mill two terminals 11 simultaneously, which is convenient and efficient. The specific structure of the milling components 72 can be selected and installed according to the milling requirements of the terminals 11, as long as the milling requirements are met. In this embodiment, the milling components 72 use a three-jaw cutter to mill the terminals 11 at the bottom of the lead-acid battery 1, ensuring processing quality and efficiency.

[0045] The lead-acid battery 1 is flipped upside down by the flipping mechanism 5 for milling. During this process, the lead slag from the milled terminals 11 falls off and does not enter the battery. This effectively prevents lead slag from falling into the battery separator paper due to incomplete subsequent cleaning, reducing worker workload and labor intensity, and improving the milling efficiency of the terminals 11. To further ensure that lead slag does not fall into the battery, a blowing mechanism is provided on the mounting base 71 facing the terminals 11 of the lead-acid battery 1 to blow away the lead slag adhering to the lead-acid battery 1.

[0046] In this embodiment, the tilting frame 53 has a tilting angle of 180 degrees. When above the conveyor, the lead-acid battery 1 is clamped or released, and after tilting 180 degrees, the lead-acid battery 1 is tilted to the position to be milled, facilitating the milling assembly 72 to perform milling operations. To ensure that the tilting frame 53 tilts to the designated position, a limiting post 21 is provided on the frame 2. When the tilting frame 53 rotates above the milling mechanism 7, the limiting post 21 provides limiting support below the tilting frame 53. At the same time, a positioning post 22 is provided on the frame 2. When the tilting frame 53 rotates above the conveying mechanism 3, the positioning post 22 provides positioning support below the tilting frame 53, which is used to limit the tilting position of the tilting frame 53, better clamp the lead-acid battery 1 and tilt it to the designated milling position, making it more precise and efficient. In addition, for processing safety, a protective cover is provided on the frame 2.

[0047] This milling equipment has a simple structure and is easy to operate. It can be used for milling the terminals of various lead-acid batteries, is highly efficient and stable, and can greatly reduce the workload and intensity of workers, thereby improving production efficiency and capacity.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
