Description

Technical Field

[0001] This utility model belongs to the field of storage battery production technology, and in particular relates to a plate brush ear mechanism for storage battery production. Background Technology

[0002] In the manufacturing process of lead-acid batteries, the plates are the core component, and their processing quality directly determines the battery's electrical performance and lifespan. During production, the top of the plate grid is cast with "tabs" for conduction and connection. In the process of assembling multiple positive and negative plates into an electrode group, tabs of the same polarity need to be aligned and welded together to form a busbar that connects to the battery terminals.

[0003] However, during casting, transportation, and storage, an oxide layer, primarily composed of lead oxide, easily forms on the surface of the electrode tabs. This oxide film has high resistance and poor solderability. If it is not removed before welding, it will lead to serious quality problems such as incomplete welds, false welds, and increased solder joint resistance. This will not only reduce the battery's discharge performance, leading to increased internal resistance and insufficient capacity, but will also cause overheating due to poor contact during long-term use, and may even trigger premature battery failure. Therefore, cleaning the electrode tab surface before the welding process, i.e., "brushing the tabs," is a crucial and indispensable step in the battery production process.

[0004] Currently, the main methods of ear brushing are divided into manual brushing and mechanical brushing. Manual brushing is inefficient, labor-intensive, and slow in production. Mechanical brushing, on the other hand, suffers from unstable quality, uneven brushing uniformity, and is prone to problems such as missed brushing, inadequate brushing, or excessive brushing that damages the ear.

[0005] In response to the aforementioned problems of low efficiency, uneven brushing uniformity, and missed or excessive brushing, this utility model designs a plate brush ear mechanism for battery production. Utility Model Content

[0006] The purpose of this utility model is to provide a plate brushing mechanism for battery production. Through the action of the plate brushing mechanism, a rotating wheel and a wire brush are configured at the corresponding position of each tab on the internal plate of the battery; and the tabs inside the battery are brushed and polished at the same time, ensuring the brushing quality and uniformity, and avoiding missed brushing or over-brushing, thus solving the problems mentioned above.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a plate brushing mechanism for battery production, comprising a battery and a plate brushing mechanism. Plates are uniformly packed inside the battery casing. The plate brushing mechanism includes a fixed frame, a lifting cylinder, and a brushing assembly. A lifting cylinder is fixedly mounted on the top of the fixed frame, and the telescopic end of the lifting cylinder passes through the fixed frame and is fixedly mounted on the brushing assembly. The lifting cylinder lowers the brushing assembly from above the battery to the point where it contacts the plate tabs, and the brushing assembly brushes the tabs. The batteries are evenly placed on the conveyor belt of a conveyor line, and fixed frames are fixedly mounted on both sides of the conveyor line.

[0008] As a preferred embodiment of this utility model, the brush assembly includes a drive motor, rotating wheels, and wire brushes; a transmission shaft is fixedly mounted on the output shaft of the drive motor; several rotating wheels are uniformly fixedly mounted on the transmission shaft; wire brushes are uniformly fixedly connected to the outer edges of the rotating wheels; the brush assembly provides rotating wheels and wire brushes at corresponding positions on each tab on the internal plates of the battery; and because all tabs inside the battery are brushed simultaneously each time, missed brushing and over-brushing are avoided.

[0009] As a preferred embodiment of this utility model, the telescopic end of the lifting cylinder is fixedly mounted with two symmetrically distributed brush ear assemblies via a connecting rod. The two brush ear assemblies are symmetrical about the center line of the telescopic end of the lifting cylinder. The brush ear assembly also includes a fixing cover. A drive motor is fixedly mounted on the outside of the fixing cover, and the rotating wheel and transmission shaft are both located inside the fixing cover. The two fixing covers are respectively fixedly mounted on both ends of the connecting rod. The fixing cover provides support for the drive motor and the transmission shaft.

[0010] As a preferred technical solution of this utility model, a limiting support plate is fixedly installed at the bottom of both ends of the fixed cover; a limiting slot is opened on the outer side of the two limiting support plates; the limiting slot contacts and engages with the top edge of the battery casing; the function of the limiting support plate and the limiting slot is to relative position the fixed cover and the electrode plates inside the battery to ensure the positional accuracy of the brushing process.

[0011] As a preferred embodiment of this utility model, the bottom of the fixed cover has a number of arc-shaped protective plates evenly arranged along the axial direction of the transmission shaft; each arc-shaped protective plate is located directly below the rotating wheel, and the two are in a clearance fit relationship; the arc-shaped protective plates are used to prevent the rotating wheel and the wire brush from causing other damage to the top of the electrode plate.

[0012] As a preferred technical solution of this utility model, the telescopic end of the lifting cylinder is fixedly installed with a positioning baffle behind the brush ear assembly; the positioning baffle is equipped with lateral positioning guide plates on both sides of the brush ear assembly; the two lateral positioning guide plates enable the battery to enter its set positioning position when it is conveyed by the conveyor belt of the conveyor line equipment, so as to ensure that the brush ear assembly performs precise brushing treatment on each tab inside the battery.

[0013] In a preferred embodiment of this invention, a stepper motor is fixedly mounted on the positioning baffle; screws A and B with opposite threads are fixedly mounted on both ends of the output shaft of the stepper motor; a lateral positioning guide plate is threadedly connected to screws A and B respectively; a sliding guide post is fixedly mounted on the side of the positioning baffle, the sliding guide post passes through the lateral positioning guide plate and slides with the lateral positioning guide plate; the stepper motor controls the two lateral positioning guide plates to move synchronously in opposite directions or synchronously in opposite directions through screws A and B with opposite threads, so as to achieve the function of clamping or releasing the battery.

[0014] This utility model has the following beneficial effects: 1. This utility model, through the action of the electrode plate brushing mechanism, configures a rotating wheel and a wire brush at the corresponding position of each electrode tab on the internal electrode plate of the battery; and since all the electrodes in the battery are brushed at the same time each time, it avoids missed brushing and over-brushing; it has the advantages of improving brushing efficiency, ensuring brushing quality and uniform brushing effect, and avoiding missed brushing and over-brushing.

[0015] 2. This utility model, through the function of the arc-shaped protective plate, has the function of preventing the rotating wheel and wire brush from causing other damage to the top of the electrode plate, and has the advantage of brushing protection.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description
