Description

Technical Field

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

[0002] The common method for forming lead-acid batteries involves quantitatively adding acid to the battery, then transferring the battery to a formation tank. The battery is placed in the formation tank, the charging connector is connected, and cooling water is circulated through the tank to a specified level. The battery is then connected to power to begin charging. However, this common method involves a relatively long time interval between adding acid and the introduction and circulation of cooling water in the formation tank, approximately 30-60 minutes. The inability to promptly circulate cooling water and begin charging after adding acid negatively impacts both the formation process and the battery's performance after formation. Utility Model Content

[0005] The technical solution of this utility model also includes an acid collection tank; the acid collection tank is set in a fixed area; when not adding acid, the acid injection head is moved above the acid collection tank by a movable bracket and handle.

[0006] The movable bracket and handle in the technical solution of this utility model are composed of a movable horizontal bracket, a movable vertical bracket and a handle; the handle is fixed on the movable vertical bracket.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1 , Figure 2 This utility model provides an embodiment of a lead-acid battery formation and acid-adding fixture, which includes an acid collection tank 1, an acid injection head positioner 2, an acid injection head 3, a movable support and handle 4, and a fixed support 5. The acid injection head 3 includes an acid injection pipe interface 11, a positioning tightening 12, a limiting block 13, and an acid injection port 14.

[0021] The fixed bracket 5 consists of a guide rail and a slider mounted on the guide rail. The guide rail is formed by rectangular rods with oblique grooves on both sides. The slider has a trapezoidal groove that mates with the guide rail. The slider is fitted onto the guide rail and can slide relative to it. The slider is equipped with a rotary joint for rotatably connecting the movable bracket and handle 4 to the fixed slider on the guide rail. The fixed bracket 5 is fixed to the production line frame above the formation tank.

[0022] The movable support and handle 4 consists of a movable horizontal support, a movable vertical support, and a handle. The movable horizontal support is a telescopic support, employing a rod-shaped telescopic design. The outer end of the inner rod is rotatably connected to the slider via a rotating joint on the slider. The movable vertical support is also a rod-shaped support, with its upper end fixedly connected to the outer end of the outer rod of the rod-shaped telescopic support via an elbow, forming a vertical shape. The handle is a round tube shaped for comfortable gripping and is horizontally fixed to the movable vertical support. The movable support and handle 4 can rotate horizontally.

[0023] There are six acid injection heads 3 in total, each consisting of an acid injection tube interface 11, a positioning tightening 12, a limiting block 13, and an acid injection port 14. The acid injection tube interface 11 is a straight, round tube. Its upper end connects to an acid metering device via an acid injection tube, which can be a transparent plastic flexible tube. Its lower end connects to the upper end of the acid injection port 14, which is also a straight, round tube and mates with the battery's acid injection hole. The limiting block 13 is located at the upper end of the acid injection port 14 and serves to limit its movement. The positioning tightening 12 consists of a thread on the outer wall of the acid injection tube interface 11 and two hexagonal nuts mounted on that thread.

[0024] The acid injection head positioner 2 is plate-shaped. The lower end of the movable vertical support of the movable bracket and handle 4 is rotatably mounted in the middle of the acid injection head positioner 2 via a rotary joint. Straight positioning holes are provided on both sides of the movable vertical support of the acid injection head positioner 2, with three acid injection heads 3 installed in each hole. The acid injection pipe interface 11 passes through the positioning hole. Two hexagonal nuts are respectively located on the outer threads of the acid injection pipe interface 11 on the upper and lower sides of the acid injection head positioner 2. Loosening the hexagonal nuts allows adjustment of the relative position of the acid injection heads 3. After the acid injection heads 3 are aligned, tightening the hexagonal nuts fixes their position, aligning each acid injection port 14 with each acid injection hole of the battery.

[0025] The acid collection tank 1 is a rectangular tank with an open top, located in a fixed area outside the formation tank. When no acid is added, the acid injection head positioner 2 and the acid injection head 3 can be moved above the acid collection tank 1 by rotating the handle relative to the fixed support 5 and the movable horizontal support and movable vertical support. When adding acid, the acid injection head positioner 2 and the acid injection head 3 are pulled out from the fixed area by the handle and moved to the formation tank, and the acid injection head positioner 2 is aligned with the acid injection hole of the battery to be added.

[0026] After the un-acidified batteries are transported to the formation tank, place them in the tank and arrange them neatly. Connect the charging connector and open the cooling water inlet valve to raise the cooling water level in the formation tank to the specified height (the cooling water outlet of the formation tank is normally open). When the acid-adding fixture is not in use, move it above the acid collection tank 1 in the designated area. To use the acid-adding fixture, hold the handle and move it from the designated area to the formation tank. Align the acid-adding head 3 on the acid-adding head positioner 2 with the battery to be acidified. Connect the acid-adding pipe interface 11 of the acid-adding head 3 to the acid-adding pipe. Align each acid-adding port 14 with each acid-adding hole of the battery. Loosen the hexagonal nut to adjust the relative position of the acid-adding head 3. After aligning the acid-adding head 3, tighten the hexagonal nut to fix its position.

[0027] The acid metering device is used to complete one acid metering operation, and the acid is then placed into the acid injection tube. The acid flows through the injection tube to the injection head and is added to the battery. After one battery is acid-added, the next battery is acid-added in the same way. After all batteries in the battery case have been acid-added, the acid-adding fixture is returned to the designated area (above acid collection tank 1) using the handle. Then, the charging circuit is connected to begin charging the batteries in the formation tank.

[0028] This invention allows the battery to be placed in a water bath in the formation tank before acid addition, which helps to reduce the immersion time after acid addition and helps to control the temperature of the electrolyte inside the battery after acid addition. The large amount of heat released by the reaction of sulfuric acid and lead oxide in lead paste during acid addition can be carried away in time by circulating water cooling, avoiding excessively high electrolyte temperature, thereby improving production efficiency, improving battery formation quality and enhancing battery performance.

[0029] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
