Description

Technical Field

[0001] This invention relates to the field of lead-acid battery manufacturing equipment technology, and more specifically, to an automatic shaping machine and method for lead-acid battery coating electrode groups. Background Technology

[0002] In the production process of lead-acid batteries, after the positive and negative plates are coated, cured, and separated, they are stacked according to polarity to form "pole groups". Before entering the subsequent assembly or casting and welding processes, these pole groups must be shaped in the front-to-back, top-to-bottom, and left-to-right directions to eliminate unevenness caused by stacking. Achieving efficient and automated shaping is a key link in improving the overall efficiency and quality consistency of the production line.

[0003] Currently, automated forming technology in the industry has evolved from early manual operation to various mechanical automation solutions. However, while pursuing forming quality, the design of these existing solutions often becomes a bottleneck restricting further improvement in the overall production line efficiency due to limitations in equipment structure and work cycle.

[0004] Most automated shaping equipment uses a single shaping station. Its workflow is essentially sequential: pole groups are fed into the shaping area -> shaping actions (front-to-back, left-to-right, etc.) are performed -> shaping is completed and the poles are sent out. During this process, loading, shaping, and unloading processes cannot overlap, resulting in significant idle waiting time. The shaping mechanism cannot receive the next pole group until it completes the processing cycle of one pole group. The processing capacity (cycle time) per unit time is limited by the most time-consuming shaping process, thus limiting capacity expansion.

[0005] Another approach attempts to process multiple pole groups at once by setting up multiple sets of shaping fixtures. While this method can process multiple pole groups simultaneously, its operating mode remains "batch processing, batch transfer." Throughout the entire cycle of clamping and alignment, shaping actions, and post-shaping release and transport, the equipment is still in a "batch processing" state, unable to achieve uninterrupted, continuous flow of pole groups. Its production cycle depends on the total processing time of a single batch, rather than a more efficient continuous flow cycle.

[0006] The existing technology of Jiqun automated shaping equipment focuses on the realization of the shaping action itself. However, in terms of the working principle and cycle design of the equipment, it has failed to break through the traditional mode of "sequential processing" or "batch processing". This results in the equipment being unable to achieve full-cycle overlapping and parallel operation of Jiqun feeding, shaping and unloading, which limits the maximum improvement of production efficiency and equipment utilization.

[0007] Therefore, a technical solution is needed that can realize continuous, automated shaping of pole groups. Summary of the Invention

[0008] The technical problem to be solved by the present invention is to overcome the technical defects of existing electrode group shaping equipment, which are slow production cycle, low equipment utilization rate and inability to form efficient continuous production line operation with the preceding and following processes due to the use of single-station sequential or batch processing mode. The present invention provides an automatic shaping machine and shaping method for lead-acid battery coating electrode groups with multi-station cyclic operation.

[0009] To achieve the above-mentioned objectives, the present invention adopts the following technical solution: An automatic shaping machine for lead-acid battery coating electrode groups includes: frame; A front-end conveying mechanism is located at the input end of the frame; A downstream conveying mechanism is located at the output end of the frame; The extreme group shaping mechanism is mounted on the frame and located between the front conveying mechanism and the rear conveying mechanism; The pole group shaping mechanism includes a support, a drive source, a rotating shaft, and at least four upper and lower shaping units that are evenly distributed circumferentially along the rotating shaft. The rotating shaft is rotatably connected to the bracket and is driven by the drive source to rotate intermittently. The upper and lower shaping units are fixed to the rotating shaft and have a shaping station for accommodating a single pole group; The drive source can drive the rotating shaft to rotate intermittently at a fixed angle, so that each of the upper and lower shaping units sequentially circulates through at least three workstations. The receiving station connects to the preceding conveyor mechanism to receive the electrode group; The shaping station is equipped with an execution component for shaping the pole group; And the unloading station, which connects with the downstream conveying mechanism to deliver the electrode group; Specifically, when the rotating shaft rotates by a fixed angle, the upper and lower shaping units located at the receiving station receive a pole group, the upper and lower shaping units located at the shaping station complete a shaping process for the pole group within them, and the upper and lower shaping units located at the unloading station send out the shaped pole group within them, thereby realizing the spatial separation and temporal parallelism of the loading, shaping, and unloading processes.

[0010] Furthermore, there are four upper and lower shaping units, arranged in a cross shape, with an angle of 90° between two adjacent upper and lower shaping units. Specifically, the 90° angle setting allows the pole groups in the upper and lower shaping units to be in a stable state without the need for additional fixing devices.

[0011] Furthermore, the four upper and lower shaping units are synchronously and cyclically positioned at the receiving station, shaping station, unloading station, and a preparation station under the intermittent rotation drive of the rotating shaft.

[0012] Furthermore, located at the shaping station, the electrode group shaping mechanism also includes left and right shaping units disposed on the support. The left and right shaping units are located on both sides of the shaping station width direction of the upper and lower shaping units. The left and right shaping units include a left drive cylinder and a right drive cylinder. The left and right shaping mechanism includes a left cylinder and a right cylinder. The piston rods of the left cylinder and the right cylinder are respectively fixedly connected to the left and right striking plates for shaping the electrode group by striking in the left and right directions.

[0013] Furthermore, the upper and lower shaping unit includes two relatively parallel partitions, a support plate, and the ejector component. The inner walls of the two partitions are respectively fixed to both ends of the support plate, forming the shaping station together. The bottom of the partition is fixedly connected to the bushing on the rotating shaft.

[0014] Furthermore, the drive source can drive the upper and lower shaping units carrying the pole groups and the pole groups inside to reciprocate at the shaping station, so that the pole groups hit the inner wall of the partition under inertia to complete the shaping in the front and back directions.

[0015] Furthermore, the angle of the reciprocating swing is 5~30°.

[0016] Furthermore, the ejector component is a lifting cylinder, the cylinder body of which is located below the support plate, and its piston rod moves upward and is connected to a support plate for supporting the electrode group for lifting, vibrating and shaping the electrode group in the vertical direction.

[0017] An automatic shaping method for an automated shaping machine includes the following steps executed cyclically: S1: Control the front conveyor mechanism to send a group of poles to be shaped into the upper and lower shaping units located at the receiving station; S2: Control the drive source to drive the rotating shaft to rotate by a fixed angle, so that the position status of each upper and lower shaping unit is updated synchronously; among them, the unit originally in the receiving station carries the pole group into the next station, the unit originally in the shaping station enters the unloading station after completing the shaping, and the unit originally in the unloading station enters the preparation station after unloading. S3: During the static period after rotation indexing, the following sub-steps are executed in parallel: At the current receiving station, proceed with the receiving step for the next electrode group; At the current shaping station, multi-directional shaping operations are performed on the pole groups located in the upper and lower shaping units of this station; At the current unloading station, the poles that have been shaped in the upper and lower shaping units at this station are transferred to the subsequent conveying mechanism.

[0018] Furthermore, the multi-directional shaping operation includes the following sequential processes: front and rear inertial impact shaping, up and down lifting and vibration shaping, and left and right slapping shaping.

[0019] Compared with the prior art, the technical solution provided by the present invention has the following significant advantages: This invention breaks through the traditional single-station sequential operation mode and adopts the principle of "multi-station cyclic flow operation". Through the rotating shaft, multiple upper and lower shaping units are driven to circulate through the receiving, shaping and unloading stations. This makes the three time-consuming processes of loading, core shaping and unloading spatially separated and completely parallel in time. The equipment is in a full-load state of "receiving, shaping and unloading" at any time, eliminating the waiting time between processes. The production cycle depends only on the slowest single process, rather than the sum of all processes, and achieves a doubling of production efficiency.

[0020] The multi-station function of this invention is achieved by driving multiple identical upper and lower shaping units to rotate and index through a single rotating shaft. The intermittent rotation of the drive source coordinates the actions of each station, enabling the completion of complex parallel operation processes with a relatively simple mechanical structure and control system. At the same time, the vertical rotation of the upper and lower shaping stations can effectively reduce equipment installation space and improve space utilization efficiency.

[0021] This invention realizes a multi-directional shaping process, including dynamic inertial impact, lifting and vibration, and synchronous tapping, ensuring that even under extremely high production rates, the product can still achieve thorough, gentle, and high-quality shaping.

Detailed Implementation

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0028] like Figure 1 and Figure 2 As shown, This embodiment provides an automatic electrode shaping machine for lead-acid battery coatings. The machine includes a frame 10, with a front conveyor mechanism 20 installed at the input end and a rear conveyor mechanism 40 installed at the output end. In this example, both are chain conveyors, which are conventional conveying mechanisms and will not be described in detail here. An electrode shaping mechanism 30 is provided on the frame 10 between the two. The electrode shaping mechanism 30 includes a bracket 301, on which a rotating shaft 302 is mounted via a bearing seat. One end of the rotating shaft 302 is connected to the output end of a drive source 303 via a coupling. The rotating shaft 302 is driven by a drive source 303. In this embodiment, the drive source 303 is a combination of a servo motor and a reducer, which can precisely control the rotating shaft 302 to perform intermittent rotation of 90 degrees and reciprocate at any angle in the vertical plane. A rectangular segment is provided on the rotating shaft 302, and a bushing is fitted on the rectangular segment. The bushing is fixed to the rotating shaft 302 by bolts. Four upper and lower shaping units 304 are integrally fixed on the bushing in a cross shape. Each upper and lower shaping unit 304 includes a bearing plate 3042 and two parallel partitions 304 vertically fixed on it. 1. This forms a U-shaped shaping station to accommodate a single pole group. The bottom of the partition plate 3041 is welded or bolted to the bushing. A lifting component, namely a lifting cylinder 3043, is bolted to the bottom of the bearing plate 3042. Its piston rod is connected upward to the receiving plate 3044. When the lifting cylinder 3043 is activated, it can push the receiving plate 3044 up and down, thereby lifting the pole group in the shaping station upward. On the bracket 301, corresponding to the "shaping station" where one of the vertical shaping units 304 stops (i.e., the vertical position), there are also left and right shaping units 305. The left and right shaping unit 305 includes a left cylinder 3051 and a right cylinder 3052. The piston rod ends of the two cylinders are respectively equipped with a left striking plate 30511 and a right striking plate 30521, which are located on both sides of the U-shaped groove of the work station. When the left cylinder 3051 and the right cylinder 3052 extend at the same time, the left striking plate 30511 and the right striking plate 30521 can strike the electrode group from the left and right sides at the same time to achieve shaping in the left and right directions. At the same time, the left striking plate 30511 and the right striking plate 30521 can be matched according to the structure of the electrode group to avoid damaging the electrode group.

[0029] An automatic shaping method for an automated shaping machine includes the following steps executed cyclically: S1: Control the front conveyor mechanism 20 to send a group of poles to be shaped into the upper and lower shaping unit 304 located at the receiving station; S2: Control the drive source 303 to drive the rotating shaft 302 to rotate by a fixed angle, so that the position status of each upper and lower shaping unit 304 is updated synchronously; among them, the unit originally in the receiving station carries the pole group into the next station, the unit originally in the shaping station enters the unloading station after completing the shaping, and the unit originally in the unloading station enters the preparation station after unloading. S3: During the static period after rotation indexing, the following sub-steps are executed in parallel: At the current receiving station, proceed with the receiving step for the next electrode group; At the current shaping station, a multi-directional shaping operation is performed on the pole group located in the upper and lower shaping units 304 at this station. At the current unloading station, the poles that have been shaped in the upper and lower shaping units 304 at this station are transferred to the downstream conveying mechanism 40.

[0030] Furthermore, the multi-directional shaping operation includes the following sequential processes: front and rear inertial impact shaping, up and down lifting and vibration shaping, and left and right slapping shaping.

[0031] Combined with appendix Figure 1 With appendix Figure 3 The working process is described in detail below. Initial state: Assume that the four upper and lower shaping units 304 are respectively located at the A receiving station, B shaping station, C unloading station, and D preparation station.

[0032] At station A: the front conveyor 20 sends a group of poles to be shaped into the U-shaped groove of the upper and lower shaping unit 304 at that location; At station B: The complete shaping process is performed on the pole group in the upper and lower shaping unit 304: First, the drive source 303 drives the rotating shaft 302 to make the unit swing back and forth at a small angle, with an swing angle of 15° in both directions. This swing causes the pole group to slightly hit the inner side of the partition plate 3041 on both the front and rear sides under the action of inertia, thereby aligning the pole group in the front and rear direction. Then, the swing returns to the vertical state. Next, the lifting component 3043 lifts the pole group to a height of no more than 20cm. Then, the piston rod quickly retracts, and the pole group falls and hits the support plate 3042 under the action of gravity, thereby achieving compaction and alignment in the upper and lower direction. The left drive cylinder 3051 and the right drive cylinder 3052 act simultaneously, pushing the left action part 30511 and the right action part 30521 to strike the pole group from both sides synchronously, aligning the pole group in the left and right direction. Then, the cylinders retract. At station C: the downstream conveyor 40 will transport the pole group that has been shaped and is located in the upper and lower shaping unit 304 at that location. Workstation D is currently idle and ready for use.

[0033] When the shaping process at station B is completed, the drive source 303 drives the rotating shaft 302 to rotate 90 degrees clockwise. After the rotation, the original station A unit carrying the electrode group moves to station B to prepare for shaping, the original station B unit moves to station C to prepare for unloading, the original station C unit moves to station D to become ready, and the original station D unit moves to station A to prepare for receiving. After the rotation indexing is completed, the machine enters the above-mentioned "parallel execution cycle" again, and so on.

[0034] Meanwhile, in order to facilitate the receiving of pole groups, the partition 3041 can be set as multiple parallel spacers inserted between the conveyor chains, so that the upper and lower shaping units 304 and the conveyor chains have a common receiving part, which can reduce the load on the entire shaping mechanism 30.

[0035] This invention, through a four-station cyclical design, enables the three main processes of receiving, shaping, and unloading to be carried out simultaneously at any time, achieving uninterrupted continuous processing of the equipment. The production efficiency is several times that of traditional single-station equipment, and the structure is compact and the operation is smooth.

[0036] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical principles and concepts disclosed in the present invention, such as using three, five, or more upper and lower shaping units, should be included within the scope of protection of the present invention.
