Description

Technical Field

[0001] This utility model belongs to the field of lead-acid battery technology, specifically relating to a lead-acid battery formation and conversion workbench. Background Technology

[0002] In recent years, the production process of lead-acid batteries has become relatively mature. Currently, battery formation mostly adopts the internal formation process, also known as the battery formation process. The battery formation process includes primary acid addition, charging formation, acid transfer, secondary acid addition, small cap heat sealing, battery cleaning, etc. Due to the variety of battery types, production lines often switch to produce different battery models. The inventors discovered through research that changing battery models requires adjustments to the position and amount of acid added, replacement of the heat-sealing mold, adjustment of the acid extraction height, and determination of the mixed acid temperature and density. The entire changeover process requires the use of measuring instruments including transparent measuring tanks, measuring cylinders, thermometers, hydrometers, pipette-type density meters, and battery limit samples. The required small mechanical tools and auxiliary tools include hex screwdrivers, wrenches, pliers, acid-resistant gloves, and lubricating oil. The numerous tools are inconvenient to handle, and during operation, the measuring instruments often come into contact with sulfuric acid electrolyte. Random placement can contaminate the work area, and placing them on a table poses a risk of spillage and acid leakage. Furthermore, glass instruments are at risk of falling and breaking. Metal tools are generally stored in toolboxes to avoid corrosion by acid and contamination of the sulfuric acid electrolyte, but this is not conducive to handling, use, or drying after cleaning.

[0007] The distance between the measuring cylinder fixing plate and the upper desktop base plate is adapted to the height of the measuring cylinder base.

[0008] The groove on the measuring cylinder fixing plate is provided with an elastic protrusion for limiting the measuring cylinder.

[0009] The base plate is rectangular, and the surrounding panels include two long panels and two short panels; the measuring tool rack and measuring cylinder fixing plate are located on one side of the long panel, the magnetic strip is located outside the other side of the long panel, and the storage box is located outside the other side of the short panel.

The acid collection box 9 is placed below the lower tabletop 7 to store a small amount of acid collected by the acid drain pipe.

[0021] The upper desktop 1 is fixed to the main support frame 6 using screws or clips. The upper desktop resembles an open box, with its bottom four sides vertically enclosed by a panel of the same material as the bottom surface. The desktop can hold a transparent measuring tank, graduated cylinder, or acid limit sample battery, while simultaneously collecting acid. The desktop is approximately 1.5 meters long, 1 meter wide, and 1 centimeter thick, while the surrounding panels are approximately 10 centimeters high and 1 centimeter thick. The dimensions of the desktop and surrounding panels can be adjusted according to requirements. The desktop and surrounding panels are made of the same material, such as polytetrafluoroethylene (PTFE) or other corrosion-resistant materials. The surrounding panels are attached to the bottom plate using hot-melt or adhesive bonding, or are integrally formed with the bottom plate. Through holes are opened on the short sides or corners of the bottom plate for connecting flexible hoses to drain acid.

[0022] The measuring tool rack 2 is vertically fixed to one corner of the upper tabletop, resembling an inverted box. It consists of two vertical plates perpendicular to the bottom and parallel to the short side rail, and a horizontal plate parallel to the bottom. The horizontal plate has holes of different sizes, and protective sleeves are installed at the holes for placing various measuring tools. The measuring tool rack 2 is made of the same material as the tabletop, using polytetrafluoroethylene or other corrosion-resistant materials. Figure 3 2-1 is a protective sleeve for a hydrometer, used to place and protect the glass hydrometer; 2-2 is a protective sleeve for a thermometer, used to place and protect the thermometer; 2-3 is a pipette-type density meter; and 2-4 is an acid level detection tube.

[0023] The measuring cylinder fixing plate 3 and the measuring instrument placement rack 2 are on the same long side of the table. The square measuring cylinder fixing plate 3 is suspended and fixed to the long side plate parallel to the bottom plate of the table, and the installation height is the same as the height of the measuring cylinder base. The measuring cylinder fixing plate has several square grooves, the size of which is the same as the diameter of the measuring cylinder to be placed, so that multiple measuring cylinders can be placed. The groove openings on the measuring cylinder fixing plate can be provided with elastic protrusions 31 for limiting the measuring cylinder.

It can collect acid adhering to measuring instruments, measuring cylinders, etc., and drain it into the bottom acid collection box 9. The acid is periodically recycled and poured into the waste acid tank.

[0030] This utility model is typically placed next to primary or secondary acid addition equipment. The upper tabletop holds various commonly used measuring tools and acid level limit samples, while the side boxes hold gloves and lubricant. Magnetic strips hold commonly used tools such as hex screwdrivers, wrenches, and pliers. The lower tabletop holds heat-sealing molds for battery production, battery caps, photoelectric sensors, and other materials. Tools are used for measurement and adjustment during battery production, and are returned to their original positions after use. The measuring tools and metal tools can be stored separately and secured, preventing haphazard placement of measuring tools that could contaminate the work area with acid, and also preventing metal tools from contacting acid and causing corrosion.
