Description

Technical Field

[0001] This utility model relates to the field of lead-acid battery technology, specifically to an automatic acid-adding device for lead-acid batteries. Background Technology

[0002] Lead-acid batteries (VRLA) are rechargeable batteries whose electrodes are primarily made of lead and its oxides, and whose electrolyte is sulfuric acid solution. In the discharged state, the positive electrode is mainly composed of lead dioxide, and the negative electrode is mainly composed of lead; in the charged state, both the positive and negative electrodes are mainly composed of lead sulfate. A single lead-acid battery cell has a nominal voltage of 2.0V, can discharge to 1.5V, and can charge to 2.4V. In practice, six single lead-acid batteries are often connected in series to form a nominal 12V lead-acid battery; 24V, 36V, and 48V batteries are also available.

[0003] Lead-acid batteries require acid addition during use. Currently, this is usually done using an acid-adding machine. The process involves manually applying anti-slip oil to the battery terminals, stamping the seal, placing an acid container on the battery, and then placing the battery with the container onto the acid-adding machine. This process requires waiting for one battery to finish adding acid before removing it, and then placing the un-acidified battery back onto the machine. This reduces the efficiency of acid addition. Utility Model Content

[0004] To address the problem that adding acid to lead-acid batteries requires waiting for one battery to finish before replacing it with an un-added battery, thus reducing the efficiency of adding acid, this invention aims to provide an automatic acid-adding device for lead-acid batteries.

[0005] To solve the above technical problems, the present invention adopts the following technical solution: an automatic acid-adding device for lead-acid batteries, comprising a base, two sets of symmetrically distributed fixing blocks fixedly installed at the top of the base, a rotating shaft rotatably passing through the top of each set of fixing blocks, two sets of symmetrically distributed pulleys fixedly installed on the outside of the rotating shafts, a transmission belt movably sleeved on the outside of each set of pulleys, a plurality of evenly distributed placement platforms provided on the outer surface of the transmission belts, connecting blocks fixedly installed on both sides of each placement platform, the connecting blocks being located at the bottom edge of the placement platform and fixedly connected to the transmission belts, an acid-adding machine fixedly installed on the upper surface of the base, a common support plate rotatably sleeved on the outside of the two rotating shafts, the support plate being located between the two transmission belts, the upper surface of the support plate being flush with the upper surface of the transmission belts, the lower surface of the support plate being flush with the lower surface of the transmission belts, a clamping assembly provided at the top of each placement platform, a motor fixedly installed at the top of the base, and the drive end of the motor being fixedly connected to one of the rotating shafts.

[0006] Preferably, a slot is provided at the center of the support plate, a first placement slot is provided on the front side of the support plate, a collection box is provided inside the first placement slot, and a connecting plate is fixedly installed on the front side of the collection box.

[0007] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0008] 1. This application enables the addition of acid to lead-acid batteries while placing un-acidified lead-acid batteries on a placement table and removing acidified lead-acid batteries, thereby improving the acid-adding efficiency of lead-acid batteries.

[0009] 2. This application enables the collection of acid remaining in the acid filling nozzle, preventing the acid from dripping directly onto the support plate and thus avoiding acid waste. Attached Figure Description

[0017] 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.

[0018] Example: Figure 1-5 As shown, this utility model provides an automatic acid-adding device for lead-acid batteries, including a base 1. Two sets of symmetrically distributed fixing blocks 11 are fixedly installed at the top of the base 1. A rotating shaft 12 rotatably passes through the top of each set of fixing blocks 11. Two sets of symmetrically distributed pulleys 13 are fixedly installed outside the rotating shaft 12. A transmission belt 14 is movably sleeved on the outside of each set of pulleys 13. Several evenly distributed placement platforms 15 are provided on the outer surface of the transmission belt 14. Connecting blocks 16 are fixedly installed on both sides of each placement platform 15, and the connecting blocks 16 are located at the bottom of the placement platform 15. At the edge of the part, the connecting block 16 is fixedly connected to the transmission belt 14. The acid adder 17 is fixedly installed on the upper surface of the base 1. The two rotating shafts 12 are rotatably sleeved with the same support plate 18. The support plate 18 is located between the two transmission belts 14. The upper surface of the support plate 18 is flush with the upper surface of the transmission belt 14, and the lower surface of the support plate 18 is flush with the lower surface of the transmission belt 14. Each placement platform 15 is provided with a clamping assembly 2 at its top. The top of the base 1 is fixedly installed with a motor 10. The drive end of the motor 10 is fixedly connected to one of the rotating shafts 12.

[0019] A slot 3 is provided at the center of the support plate 18, and a first placement slot 31 is provided on the front side of the support plate 18. A collection box 32 is provided inside the first placement slot 31, and a connecting plate 33 is fixedly installed on the front side of the collection box 32.

[0020] The clamping assembly 2 includes a fixing plate 20, which is fixed to a placement platform 15. A fixing seat 21 is fixedly installed on the side of the placement platform 15 away from the fixing plate 20. A threaded rod 22 is threadedly connected to the top of the fixing seat 21. A rotating wheel 23 is fixedly installed on the side of the threaded rod 22 away from the fixing plate 20. A handle 24 is fixedly installed on the side of the rotating wheel 23 away from the threaded rod 22. A clamping plate 25 that mates with the fixing plate 20 is fixedly installed on the side of the threaded rod 22 away from the rotating wheel 23. The clamping assembly 2 also includes two symmetrically distributed trapezoidal blocks 4, which are fixed at the bottom edge of the clamping plate 25. A trapezoidal groove 41 that mates with the trapezoidal blocks 4 is provided at the top edge of the placement platform 15. By setting the clamping assembly 2... When the lead-acid battery is placed on the placement platform 15 and one side of the outer wall of the lead-acid battery is in contact with the fixing plate 20, the handle 24 is then turned, which drives the rotating wheel 23 and the threaded rod 22 to rotate. The clamping plate 25 is limited by the cooperation between the trapezoidal block 4 and the trapezoidal groove 41, and will not rotate with the rotation of the threaded rod 22. This causes the clamping plate 25 to drive the trapezoidal block 4 to move towards the fixing plate 20 on the trapezoidal groove 41, so that the clamping plate 25 is in contact with the other side of the outer wall of the lead-acid battery. This achieves clamping of the lead-acid battery placed on the placement platform 15, and prevents the lead-acid battery from shaking during movement, which would cause the acid filling position of the lead-acid battery to deviate from the acid filling nozzle on the acid filling machine 17, thus affecting the acid filling of the lead-acid battery.

[0021] Each placement platform 15 has a second placement slot 5 at the top center. By setting the second placement slot 5, it is clearer which position on the placement platform 15 the lead-acid battery needs to be placed so that the acid filling position of the lead-acid battery corresponds to the acid filling nozzle on the acid filling machine 17, thereby improving the accuracy between the lead-acid battery and the acid filling nozzle.

[0022] Each placement platform 15 is fixedly installed with a slider 6 at its bottom end. The outer surface of the support plate 18 is provided with a groove 61 that works with the slider 6. By setting the slider 6 and the groove 61, when the transmission belt 14 rotates, it drives the connecting block 16 and the placement platform 15 to move. While the placement platform 15 moves, the slider 6 moves in the groove 61, thereby increasing the stability of the movement of the placement platform 15.

[0023] A rubber sleeve 7 is fixedly installed on the outside of the handle 24. Several annularly distributed anti-slip particles are fixedly installed on the outside of the rubber sleeve 7. By setting the rubber sleeve 7, the comfort between the hand and the handle 24 is increased, making it easier to rotate the handle 24 to drive the rotating wheel 23 and the threaded rod 22 to rotate.

[0024] Working principle: In actual use, lead-acid batteries containing acid containers are placed on the placement platform 15 below the acid filling nozzle and on the placement platform 15 to the right of the acid filling machine 17, respectively. Then, the lead-acid batteries are clamped and fixed by the clamping assembly 2. Then, the acid filling machine 17 is started, so that the acid filling nozzle moves down to fit with the acid container on the lead-acid battery, and then acid is added. After the first lead-acid battery is added, the motor 10 is started, which drives one of the rotating shafts 12 to rotate. The rotation of the rotating shaft 12 drives two sets of pulleys 13 to rotate. The rotation of the two sets of pulleys 13 drives the transmission belt 14 to rotate. As the transmission belt 14 rotates, it drives the other two sets of pulleys 13 to rotate, thereby driving the other rotating shaft 12 to rotate at the same time. As the transmission belt 14 rotates, it drives the connecting block 16, the placement platform 15, and the lead-acid batteries on the placement platform 15 to move.

[0025] When the next placement platform 15 moves to the bottom of the acid filling nozzle on the acid filling machine 17, the drive belt 14 stops rotating. Then, the lead-acid battery is acidified by the acid filling machine 17. When the lead-acid battery is acidified, the acid-filled lead-acid battery can be removed. After removal, the lead-acid battery is placed on the placement platform 15 on the right side of the acid filling machine 17 and then fixed. When it is placed, the lead-acid battery on the previous placement platform 15 is acidified. At the same time, the drive belt 14 starts rotating again. The operation can be repeated.

[0026] After the lead-acid battery is filled with acid, the acid remaining in the filling nozzle will drip from the empty slot 3 into the collection box 32, instead of dripping onto the support plate 18, thus collecting the acid and avoiding waste. Then, the connecting plate 33 and the collection box 32 are pulled out from the first placement slot 31 periodically to empty the acid in the collection box 32. When placing the collection box 32, the collection box 32 and the connecting plate 33 are passed through the front drive belt 14 and then inserted into the first placement slot 31 for the next acid collection.

[0027] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
