Description

Technical Field

[0001] This invention belongs to the technical field of storage battery production and processing, specifically an acid-adding device for storage batteries. Background Technology

[0002] In the production process of lead-acid batteries, before acid injection, the acid filling pot of the circulating tool needs to be precisely inverted and pressed tightly against the battery filling port to form a sealed cavity to complete the subsequent vacuum acid filling, formation and degassing processes. The coaxiality and sealing consistency of the acid filling pot directly determine the battery acid injection yield.

[0003] Currently, the mainstream acid-adding operations in the industry are divided into two solutions: manual acid-adding and separate simple tooling. The manual method relies on the operator holding the acid-adding pot and pressing it down on the battery filling hole, which has obvious drawbacks: First, it is difficult to unify the force and alignment accuracy of manual placement, which easily leads to problems such as the acid-adding pot being crooked and the sealing ring not fitting properly; Second, both the acid-adding pot and the electrolyte are highly corrosive, and long-term close-range manual operation poses safety hazards such as sulfuric acid burns and inhalation of volatile acid fumes; Third, a single workstation can only complete the acid-adding pot for one row of batteries at a time, requiring frequent replenishment of the acid-adding pot, resulting in high labor intensity, slow production cycle, and incompatibility with automated mass production lines.

[0004] While some acid-adding fixtures can replace manual pressing of the filling tank, they are mostly split designs and still have several technical shortcomings: First, the battery positioning structure often uses dual-cylinder independent clamping and correction, making it difficult to match the synchronization of the two sets of cylinders. This results in cumbersome debugging, high component costs, and the battery is prone to unilateral displacement during clamping, making it difficult to ensure that the battery is centered and aligned, leading to large alignment deviations when pressing down the acid-adding tank. Second, the acid-adding tank lacks a batch storage structure for material feeding, allowing only single-row feeding. This necessitates frequent equipment shutdowns for replenishment, resulting in poor production line continuity and limited capacity. Third, the fastening actuator lacks a combined module for rotational transposition and lateral fine-tuning, enabling only vertical pressing operations. The acid-adding tank's transfer and alignment adjustment strokes are limited, resulting in insufficient fastening accuracy and frequent occurrences of the acid-adding tank failing to fully embed into the filling port or seal failure. Summary of the Invention

[0005] This invention provides an acid-adding device for storage batteries, which addresses the technical problems of existing acid-adding devices that rely on manual operation or traditional split-type tooling, resulting in poor alignment accuracy, low safety, low efficiency, poor synchronization of the dual cylinders in the tooling, lack of batch material storage, insufficient alignment adjustment capability, and poor fastening accuracy and sealing. These issues make it difficult to meet the technical requirements of automated mass production.

[0010] As a further technical solution of the present invention, the lateral length of the slide plate is less than the lateral length of the U-shaped plate, a groove is provided on the inner side of the U-shaped plate, and slide rails adapted to the groove are fixed on both sides of the slide plate.

[0011] As a further technical solution of the present invention, the fixing component includes a fixing plate, a movable plate is slidably installed on the bottom side of one side of the fixing plate, two driving push rods are fixed on the top of the fixing plate, and a connecting plate is fixed on the driving end of the driving push rods.

[0012] As a further technical solution of the present invention, the fixed base is located between the two drive push rods, and a fastening electric cylinder is fixed on the top of the U-shaped plate. The drive end of the fastening electric cylinder is fixedly connected to the fixed base. The fixed plate is L-shaped, and anti-slip pads are fixed on the opposite surfaces of the fixed plate and the moving plate.

[0013] As a further technical solution of the present invention, the centering mechanism includes two support seats fixed to the conveying rollers. Guide rods are fixedly installed inside the support seats. A middle crossbeam is fixed to the outside of the two guide rods. Two sliding crossbeams are also slidably installed outside the two guide rods. The two sliding crossbeams are located on both sides of the middle crossbeam.

[0016] The beneficial effects of this invention are: This invention features a centering mechanism. After the battery is conveyed by the conveying rollers, it can be centered using the centering mechanism. By retracting the push cylinder, one of the sliding beams moves. As the sliding beam moves, the swing rod hinged to it swings, which in turn causes the hinge plate to rotate. The angle between the swing rod and the hinge plate decreases, causing the other swing rod to swing, which in turn causes the other sliding beam to move. The two sliding beams approach each other, and the battery is centered and corrected using two rows of limiting posts. This allows the battery to maintain a vertical posture, making it easier to accurately press the acid filling pot into the filling port during the acid filling operation. By setting up a fastening mechanism, the acid filler can be moved above the battery by the rotation of the drive turntable. The slide plate is moved by the drive push rod, and the fixed base is moved down by the fastening electric cylinder. The acid filler can be accurately fastened into the battery's filling port, further improving the fastening accuracy. By setting up a feeding mechanism, multiple rows of acid-adding pots are fastened inside the buckle plate, enabling sequential feeding operations and eliminating the need for manual fastening of the acid-adding pots. Before operation, simply fasten the multiple rows of acid-adding pots inside the buckle plate and use the support frame to support them, effectively improving the efficiency of fastening the acid-adding pots.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] like Figure 1 - Figure 6 As shown, the acid-adding device for storage batteries includes a conveying roller 1, a feeding platform 2 fixed on one side of the conveying roller 1, a fastening mechanism 3 rotatably mounted on the top of the feeding platform 2, and a feeding mechanism 4 also supported on the top of the feeding platform 2. The feeding mechanism 4 is located on one side of the fastening mechanism 3, and an alignment mechanism 5 for aligning the storage batteries is fixed at the bottom of the conveying roller 1. The feeding mechanism 4 includes a support frame 41, a buckle plate 42 is fixed inside the support frame 41, and multiple rows of acid-adding pots 44 are fastened inside the buckle plate 42. A fixed horizontal plate 45 is fixed on the top of each row of acid-adding pots 44. Side grooves 43 are opened on both sides of the support frame 41 corresponding to the two sides of each row of acid-adding pots 44.

[0022] The surface of the buckle plate 42 has multiple rows of snap-fit ​​grooves, and the acid pot 44 is snapped in an inverted position inside the snap-fit ​​grooves.

[0023] Specifically, by setting multiple rows of snap-fit ​​grooves, each row of acid-adding pots 44 can be vertically fixed by simply snapping the drain end of the acid-adding pot 44 into the snap-fit ​​groove. A side groove 43 is also provided to facilitate the installation of the acid-adding pot 44 onto the buckle plate 42, providing operating space.

[0024] The fastening mechanism 3 includes a drive turntable 31, a telescopic sleeve plate 39 fixed to the top of the drive turntable 31, and a U-shaped plate 32 fixed to the top of the telescopic sleeve plate 39. A slide plate 33 is slidably installed inside the U-shaped plate 32, and a push plate 34 is fixed to the top of the slide plate 33. Two drive push rods 35 are fixed to the side of the top of the U-shaped plate 32 away from the push plate 34. The drive end of the drive push rod 35 is fixed to the side wall of the U-shaped plate 32. A fixing component 38 is provided at the bottom of the U-shaped plate 32. A lifting electric cylinder 36 and a row of telescopic rods 37 are fixed to the top of the drive turntable 31. The lifting electric cylinder 36 and the telescopic rods 37 are located on both sides of the telescopic sleeve plate 39, and the telescopic ends of the lifting electric cylinder 36 and the telescopic rods 37 are fixedly connected to the bottom surface of the U-shaped plate 32.

[0025] Specifically, the lifting electric cylinder 36 drives the U-shaped plate 32 to rise, and the drive push rod 35 drives the sliding plate 33 to move laterally, which can facilitate the movement of the fixing component 38 to the position above the acid filling pot 44. Then, the lifting electric cylinder 36 drives the U-shaped plate 32 to move down, which can move the fixing component 38 to dock with the acid filling pot 44, making it easier to grab the acid filling pot 44.

[0026] The telescopic sleeve 39 includes a fixed sleeve and a connecting plate. The connecting plate is slidably installed inside the fixed sleeve, and the top of the connecting plate is fixedly connected to the bottom surface of the U-shaped plate 32.

[0027] Specifically, the telescopic sleeve 39 extends and retracts as driven by the lifting electric cylinder 36, and the telescopic rod 37 extends and retracts adaptively, thereby improving the stability of the U-shaped plate 32 during lifting.

[0028] The lateral length of the slide plate 33 is less than the lateral length of the U-shaped plate 32. The inner side of the U-shaped plate 32 is provided with a sliding groove, and the two sides of the slide plate 33 are fixed with sliding rails that are adapted to the sliding groove.

[0029] Specifically, the slide plate 33 is set to be less than the lateral length of the U-shaped plate 32, providing installation space for the telescopic rod 37 and the drive end of the lifting electric cylinder 36.

[0030] The fixing assembly 38 includes a fixing plate 381. A movable plate 385 is slidably mounted on one bottom side of the fixing plate 381. Two drive push rods 382 are fixed to the top of the fixing plate 381, and a connecting plate 383 is fixed to the drive end of each drive push rod 382. A connecting rod 384, which is fixedly connected to the connecting plate 383, is fixed to the outer side of the movable plate 385. A fixing seat 386 is also fixed to the top of the fixing plate 381. The fixing seat 386 is located between the two drive push rods 382. A latching electric cylinder is fixed to the top of the U-shaped plate 32. The drive end of the latching electric cylinder is fixedly connected to the fixing seat 386. The fixing plate 381 is L-shaped, and anti-slip pads are fixed to the opposite surfaces of the fixing plate 381 and the movable plate 385.

[0031] Specifically, as the electric cylinder drives the fixed base 386 to move down, the fixed plate 381 first adheres to one side of the acid filling pot 44, and the moving plate 385 moves through the drive push rod 382, ​​which, together with the fixed plate 381, clamps the two sides of the acid filling pot 44, thus facilitating the gripping of the acid filling pot 44.

[0032] The centering mechanism 5 includes two support seats 51 fixed to the conveyor roller 1. Guide rods 52 are fixedly installed inside the support seats 51. A middle crossbeam 53 is fixed to the outside of the two guide rods 52. Two sliding crossbeams 54 are also slidably installed outside the two guide rods 52. The two sliding crossbeams 54 are located on both sides of the middle crossbeam 53. Several limiting posts 55 are fixed to the top of the sliding crossbeams 54. A pushing electric cylinder is fixed to the bottom of the middle crossbeam 53 through a mounting plate. A driven seat 57 is fixed to the bottom of one of the sliding crossbeams 54. The driving end of the pushing electric cylinder is fixedly connected to the driven seat 57. A hinge plate 56 is movably hinged to the bottom of the mounting plate. A swing rod 59 is hinged to both ends of the hinge plate 56. An extension seat 58 is fixed to the far ends of the bottom of the two sliding crossbeams 54. The far ends of the two swing rods 59 are respectively hinged to the extension seats 58 at the corresponding positions. The limiting post 55 consists of a support post and a contact post. The support post is located within the gap of the conveying roller 1, and the contact post is fixed to the top of the support post. Both sliding beams 54 have sleeves embedded inside that are slidably connected to the guide rod 52.

[0033] Specifically, the retraction of the push-pull electric cylinder drives one of the sliding crossbeams 54 to move. As the sliding crossbeam 54 moves, it drives the swing rod 59 hinged to it to swing. In turn, the swing rod 59 drives the hinge plate 56 to rotate. The angle between the swing rod 59 and the hinge plate 56 decreases, causing the other swing rod 59 to swing, thereby driving the other sliding crossbeam 54 to move. The two sliding crossbeams 54 move closer together, thereby using two rows of limit posts 55 to center and correct the battery.

[0034] This invention discloses an acid-adding device for storage batteries. In use, the batteries are transported by a conveyor roller 1. The batteries are placed one by one on the top of the conveyor roller 1 and first enter the centering area of ​​the centering mechanism 5, at which point the conveyor roller 1 stops.

[0035] The retraction of the electric cylinder drives one of the sliding beams 54 to move. As the sliding beam 54 moves, it causes the swing rod 59, which is hinged to it, to swing. In turn, the swing rod 59 drives the hinge plate 56 to rotate. The angle between the swing rod 59 and the hinge plate 56 decreases, causing the other swing rod 59 to swing, which in turn drives the other sliding beam 54 to move. The two sliding beams 54 move closer together, and the battery is centered and corrected by the two rows of limit posts 55. At this time, the battery is located at the center line of the conveyor roller 1 and is placed horizontally.

[0036] Then, the material is fed through the fastening mechanism 3. The feeding mechanism 4 first stores multiple rows of acid-adding pots 44. The multiple rows of acid-adding pots 44 are upside down and fastened to the fastening plate 42. Each row of acid-adding pots 44 has a fixed horizontal plate 45 on its top, which makes it easy to connect the acid-adding pots 44 together.

[0037] When the fastening mechanism 3 is feeding material, it first drives the U-shaped plate 32 to rise through the lifting electric cylinder 36, which in turn drives the fixing component 38 to rise. Then, it drives the slide plate 33 to move laterally through the drive push rod 35, aligning the fixing component 38 above the acid adding pot 44.

[0038] The fixing plate 381 is first attached to one side of the acid-adding pot 44 by the electric cylinder driving the fixing base 386 to move down. The moving plate 385 moves by driving the push rod 382, ​​and works with the fixing plate 381 to clamp the two sides of the acid-adding pot 44, so as to facilitate the gripping of the acid-adding pot 44.

[0039] The drive turntable 31 is rotated 180° to rotate the acid filling pot 44 above the conveying roller 1. The drive push rod 35 drives the slide plate 33 to move laterally to adjust the position of the acid filling pot 44 so that it is aligned directly above the battery's liquid filling port. Then, the locking cylinder drives the fixing seat 386 to move down, inserting the acid filling pot 44 into the battery's liquid filling port. The drive push rod 382 drives the moving plate 385 to disengage from the acid filling pot 44. The locking cylinder drives the fixing seat 386 to rise, thus completing the acid filling pot operation.

[0040] Then start the conveyor roller 1 to send out the battery after it has been processed by the acid pot, drive the turntable 31 to reset, and start grabbing the next row of acid pots 44.

[0041] The above description is merely an example and illustration of the structure of the present invention. Those skilled in the art can make various modifications or additions to the specific embodiments described, or use similar methods to replace them, as long as they do not deviate from the structure of the invention or exceed the scope defined in the claims, all of which should fall within the protection scope of the present invention.
