Description

Technical Field

[0001] This invention belongs to the technical field of electrode plate production equipment, and particularly relates to a lead-acid battery electrode plate stacking and receiving device and method. Background Technology

[0002] Lead-acid batteries are rechargeable batteries whose electrodes are primarily made of lead and its oxides, and whose electrolyte is sulfuric acid solution. They are among the most produced and widely used rechargeable batteries in the world. Their basic structure includes positive and negative plates, separators, and a container for dilute sulfuric acid. Their working principle is based on a reversible chemical reaction: during discharge, the active materials at the positive and negative electrodes react with the electrolyte to produce lead sulfate, releasing electrical energy; during charging, under the influence of an external current, the lead sulfate is reduced back to its original form, thus storing energy. The main advantages of lead-acid batteries are low cost, readily available raw materials, good high-rate discharge performance, a wide operating temperature range, and mature recycling technology with high recyclability.

[0003] Currently, conventional battery production requires automated plate coating technology. Under current technology, coating and plate separation are automated processes. Plates from the drying kiln flow out one by one, and in the subsequent process, they need to be stacked in groups of about 30. Some manufacturers stack them manually, while others use negative pressure stacking. Manual stacking requires a large amount of manpower and is labor-intensive. Negative pressure stacking is sometimes unstable; the negative pressure often fails to hold the plates, causing them to fall off and break, resulting in significant waste and increased costs.

[0004] Therefore, there is an urgent need for a lead-acid battery plate stacking and receiving device. Summary of the Invention

[0005] The purpose of this invention is to provide a lead-acid battery electrode plate stacking device and method, which has a scientific and reasonable structure, is simple and convenient to operate, is stable and reliable in operation, reduces electrode plate damage, and greatly improves the electrode plate stacking efficiency, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A lead-acid battery electrode plate receiving and stacking device includes a frame for mounting and supporting various actuators; a front-end conveying mechanism and a rear-end conveying mechanism, respectively connected to both ends of the frame for transferring the electrode plates; a height difference exists between the front-end conveying mechanism and the rear-end conveying mechanism, with the discharge end of the front-end conveying mechanism located above the feed end of the rear-end conveying mechanism; a main receiving mechanism includes a lifting assembly and a vertical receiving assembly, the lifting assembly being connected to the frame, and the vertical receiving assembly being connected to the power output end of the lifting assembly, the lifting assembly being located at the junction of the front-end conveying mechanism and the rear-end conveying mechanism; when the lifting assembly drives the vertical receiving assembly to rise, the electrode plates on the front-end conveying mechanism are transferred to the vertical receiving assembly for stacking; when the lifting assembly drives the vertical receiving assembly to fall, the electrode plates stacked on the vertical receiving assembly fall onto the rear-end conveying mechanism.

[0007] A further improvement of the present invention is that the front-end conveying mechanism and the rear-end conveying mechanism are respectively a front chain conveyor and a rear chain conveyor, and the front chain conveyor and the rear chain conveyor are respectively provided with a front chain group and a rear chain group, which support the electrode plate and drive the electrode plate to move linearly; a gantry frame is connected to the frame at the discharge end of the chain conveyor, and a photoelectric sensor is connected to the gantry frame to detect the amount of electrode plate material.

[0008] A further improvement of the present invention is that a feed roller is rotatably connected to the frame at the feed end of the front chain conveyor, the feed roller is located at the feed section of each conveying chain of the chain assembly, and the drive shaft of the front chain conveyor is connected to the roller shaft of the feed roller via a drive chain; guide rollers are connected to the drive shaft and driven shaft of the front chain conveyor, and the guide rollers are arranged alternately with each conveying chain of the front chain assembly.

[0009] A further improvement of the present invention is that the lifting assembly includes a vertically arranged electric screw linear slide module connected to the side of the frame; the vertical connecting plate assembly includes a crossbeam, one end of which is connected to the slide base of the electric screw linear slide module, and the crossbeam extends to the bottom end of the rear chain group of the rear chain conveyor; several vertical connecting plate plates are connected side by side on the crossbeam, and each vertical connecting plate plate is arranged alternately with each conveyor chain of the rear chain group.

[0010] A further improvement of the present invention includes a transition piece connection mechanism, which is connected to the frame and located above the feed end of the rear conveying mechanism.

[0011] A further improvement of the present invention is that the transition bonding mechanism includes a support, on which a transfer component and a baffle plate are connected; a transverse bonding component is connected to the transfer component, and comb-shaped transverse bonding components and comb-shaped vertical bonding components are arranged alternately. The transfer component drives the transverse bonding components to move up, down, forward, and backward, thereby receiving the electrode sheet conveyed by the front-end conveying mechanism and placing it on the vertical bonding component.

[0012] A further improvement of the present invention is that the transfer assembly includes a first cylinder vertically connected to the top of the support, the power output end of the first cylinder being connected to a lifting plate, and the lifting plate being connected to the support via a sliding rod and sleeve assembly A; the bottom end of the lifting plate is connected to a second cylinder arranged along the moving direction of the electrode plate, the power output end of the second cylinder being connected to a base, and the base being connected to the lifting plate via a sliding rod and sleeve assembly B; and a transverse connecting plate is connected to the base.

[0013] A further improvement of the present invention is that the baffle is connected to the bracket, and the baffle plate is close to the end face of the vertical connecting plate assembly away from the front end conveying mechanism, for blocking the electrode plate falling from the front end conveying mechanism, and the baffle plate is provided with a notch for the horizontal connecting plate assembly to pass through.

[0014] A further improvement of the present invention is that the discharge end of the frame of the front chain conveyor is rotatably connected to the frame, and the inlet end is placed on the frame; a third cylinder is hinged on the frame, a support plate is connected to the bottom end of the front chain conveyor, and the other end of the third cylinder is hinged to the support plate. When the third cylinder extends, it can lift the inlet end of the front chain conveyor.

[0015] A method for stacking lead-acid battery plates, using the aforementioned lead-acid battery plate stacking device, includes the following steps: Step 1: The plates flowing out of the front drying kiln are transferred to the front chain conveyor for accelerated conveying via the conveying mechanism.

[0016] Step 2: The electrode plates fall from the discharge end of the front chain conveyor onto the vertical receiving plate for stacking. When the number of plates reaches the program-specified number, the electric screw linear slide module drives the vertical receiving plate to descend rapidly, and the stacked electrode plates fall onto the rear chain conveyor for transfer to the next process.

[0017] Step 3: As the vertical receiving plate descends rapidly, electrode plates continue to fall from the discharge end of the front chain conveyor. At this time, driven by the first and second cylinders, the horizontal receiving plate quickly takes over from the vertical receiving plate to receive the continuously falling electrode plates. When the horizontal receiving plate has received a certain number of electrode plates, the vertical receiving plate rises to take over the receiving action, and the electrode plates stacked on the horizontal receiving plate fall onto the vertical receiving plate. However, the number of electrode plates on the vertical receiving plate has not reached the number specified in the program, and the vertical receiving plate continues to receive electrode plates.

[0018] Step 4: When the number of plates on the vertical receiving plate reaches the number specified in the program, the vertical receiving plate descends rapidly, and the stacked plates fall onto the rear chain conveyor; the horizontal receiving plate quickly takes over from the vertical receiving plate to receive the plates, and this cycle repeats.

[0019] The beneficial effects of this invention are: The lead-acid battery electrode plate stacking device and method of the present invention have a scientific and reasonable structure, are simple and convenient to operate, are stable and reliable in operation, reduce electrode plate damage, and greatly improve the electrode plate stacking efficiency.

[0020] The lead-acid battery electrode plate stacking device and method of the present invention, wherein the feeding roller and guide roller on the front chain conveyor provide rolling support for the electrode plates, so that when the electrode plates enter the chain conveyor from the upstream equipment or manual feeding port, they can transition smoothly, avoiding jamming, jumping or impact caused by direct contact with the chain, thus protecting the electrode plates and the conveyor belt; direct contact between the electrode plates and a stationary or low-speed chain will generate large sliding friction; the guide roller and feeding roller replace sliding contact with rolling contact, significantly reducing frictional resistance and also reducing wear on the chain, chain plates and electrode plate surfaces.

[0021] The lead-acid battery electrode plate receiving and stacking device and method of the present invention adds a transition electrode plate receiving mechanism to ensure that when the main electrode plate receiving mechanism places the electrode plate on the rear conveying mechanism, the transition electrode plate receiving mechanism can receive the electrode plate continuously falling from the front conveying mechanism, so that the front conveying mechanism does not need to stop and further improves the working efficiency.

[0022] The lead-acid battery electrode plate receiving and stacking device and method of the present invention can rotate the front-end conveying mechanism under the drive of the third cylinder. When the device malfunctions, the conveying mechanism passing through the drying kiln can disconnect from the front-end conveying mechanism without stopping the machine. The electrode plates can be temporarily discharged and stored in the collection box before entering the front-end conveying mechanism, which avoids the electrode plates staying in the drying kiln for a long time and being damaged, and reduces unnecessary economic losses.

Detailed Implementation

[0033] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments.

[0034] Example 1: As Figures 1-10 As shown, a lead-acid battery electrode plate receiving and stacking device includes a frame 1 for mounting and supporting various actuators; a front-end conveying mechanism 2 and a rear-end conveying mechanism 3, respectively connected to both ends of the frame 1 for transferring electrode plates 7; a height difference is provided between the front-end conveying mechanism 2 and the rear-end conveying mechanism 3, and the discharge end of the front-end conveying mechanism 2 is located above the feed end of the rear-end conveying mechanism 3; a main receiving mechanism 4 includes a lifting assembly and a vertical receiving assembly, the lifting assembly is connected to the frame 1, the vertical receiving assembly is connected to the power output end of the lifting assembly, and the lifting assembly is located at the junction of the front-end conveying mechanism 2 and the rear-end conveying mechanism 3; when the lifting assembly drives the vertical receiving assembly to rise, the electrode plates 7 on the front-end conveying mechanism 2 are transferred to the vertical receiving assembly for stacking; when the lifting assembly drives the vertical receiving assembly to fall, the electrode plates 7 stacked on the vertical receiving assembly fall onto the rear-end conveying mechanism 3.

[0035] The front-end conveying mechanism 2 and the rear-end conveying mechanism 3 are respectively a front chain conveyor 201 and a rear chain conveyor 301. The front chain conveyor 201 and the rear chain conveyor 301 are respectively equipped with a front chain group 202 and a rear chain group 302. The front chain group 202 and the rear chain group 302 support the electrode plate 7 and drive the electrode plate 7 to move linearly. A gantry frame 203 is connected to the frame at the discharge end of the chain conveyor. A photoelectric sensor is connected to the gantry frame 203 to detect the amount of material in the electrode plate 7.

[0036] A feed roller 204 is rotatably connected to the frame at the feed end of the front chain conveyor 201. The feed roller 204 is located at the feed section of each conveyor chain of the chain assembly, and the drive shaft of the front chain conveyor 201 is connected to the roller shaft of the feed roller 204 through a drive chain. Guide rollers 205 are connected to the drive shaft and driven shaft of the front chain conveyor 201, and the guide rollers 205 are arranged alternately with each conveyor chain of the front chain assembly 202.

[0037] The lifting assembly includes a vertically mounted electric screw linear slide module connected to the side of the frame 1; the vertical connecting plate assembly includes a crossbeam 402, one end of which is connected to the slide base of the electric screw linear slide module, and the crossbeam 402 extends to the bottom of the rear chain group 302 of the rear chain conveyor 301; several vertical connecting plate plates 403 are connected in parallel on the crossbeam 402, and each vertical connecting plate 403 is arranged alternately with each conveyor chain of the rear chain group 302.

[0038] Example 2: This example is a further improvement on Example 1. The main improvement is that in Example 1, when the main receiving mechanism 4 places the stacked electrode plates 7 onto the rear conveying mechanism 3, the front conveying mechanism 2 needs to stop, thus reducing work efficiency. In this example, the above-mentioned defects can be avoided. Specifically: It also includes a transition piece connection mechanism 5, which is connected to the frame 1 and is located above the feed end of the rear conveying mechanism 3.

[0039] The transition bonding mechanism 5 includes a bracket 501, on which a transfer component and a baffle plate 507 are connected. A transverse bonding component is connected to the transfer component. The comb-shaped transverse bonding component and the comb-shaped vertical bonding component are arranged alternately. The transfer component drives the transverse bonding component to move up, down, forward, and backward, thereby receiving the electrode sheet conveyed by the front-end conveying mechanism 2 and placing it on the vertical bonding component.

[0040] The transfer assembly includes a first cylinder 502 vertically connected to the top of the bracket 501. The power output end of the first cylinder 502 is connected to a lifting plate 503, and the lifting plate 503 is connected to the bracket 501 through a sliding rod and sliding sleeve assembly A. The bottom end of the lifting plate 503 is connected to a second cylinder 504 arranged along the moving direction of the pole plate 7. The power output end of the second cylinder 504 is connected to a base 505, and the base 505 is connected to the lifting plate 503 through a sliding rod and sliding sleeve assembly B. A transverse connecting plate 506 is connected to the base 505.

[0041] The baffle is connected to the bracket 501, and the baffle plate 507 is close to the end face of the vertical connecting plate assembly away from the front end conveying mechanism 2, which is used to block the electrode plate 7 falling from the front end conveying mechanism 2, and the baffle plate 507 is provided with a notch 508 for the horizontal connecting plate assembly to pass through.

[0042] In this embodiment, the front-end conveying mechanism 2 can be flipped under the drive of the third cylinder 6. When the device malfunctions, the electrode plate 7 can be discharged into the collection box before entering the front-end conveying mechanism 2, thus avoiding the electrode plate 7 from staying in the drying kiln for a long time and being damaged.

[0043] Apart from the above, this embodiment is exactly the same as Embodiment 1, and will not be described again here.

[0044] Example 3: This example is a further improvement on Example 2. The main improvement is that if a malfunction occurs during use in Example 2, the conveying mechanism of the drying kiln needs to be stopped, and the electrode plate 7 will be damaged if it stays in the drying kiln for a long time. In this example, the above-mentioned defects can be avoided. Specifically: The discharge end of the front chain conveyor 201 is rotatably connected to the frame 1, and the feed end is placed on the frame 1. A third cylinder 6 is hinged on the frame 1. A support plate 206 is connected to the bottom end of the front chain conveyor 201. The other end of the third cylinder 6 is hinged to the support plate 206. When the third cylinder 6 extends, it can lift the feed end of the front chain conveyor 201.

[0045] In this embodiment, the front-end conveying mechanism 2 can be rotated under the drive of the third cylinder 6. When the device malfunctions, the conveying mechanism passing through the drying kiln can disconnect from the front-end conveying mechanism 2 without stopping the machine. The electrode plate 7 can be temporarily discharged and stored in the collection box before entering the front-end conveying mechanism 2, which avoids the electrode plate 7 from staying in the drying kiln for a long time and being damaged, thus reducing unnecessary economic losses.

[0046] Apart from the above, this embodiment is exactly the same as embodiment 2, and will not be described again here.

[0047] Example 4: This example differs from Example 3, specifically: In this embodiment, the front chain assembly 202 on the front chain conveyor 201, the rear chain assembly 302 on the rear chain conveyor 301, the vertical connecting plate 403, and the horizontal connecting plate 506 are all arranged in parallel as two sets. This enables synchronous stacking of the two electrode plates 7, further improving the stacking efficiency of the electrode plates 7.

[0048] Apart from the above, this embodiment is exactly the same as embodiment 3, and will not be described again here.

[0049] The specific working principle of this invention is as follows: The present invention is equipped with a PLC controller. The servo motors of the front chain conveyor 201 and the rear chain conveyor 301, the servo motor of the electric lead screw linear slide module 401, photoelectric sensors, and the solenoid valves of each cylinder are all electrically connected to the PLC controller to realize the coordinated operation of each mechanism.

[0050] During operation, the electrode plate 7 flowing out of the front drying kiln is transferred to the front chain conveyor 201 for accelerated conveying through the conveying mechanism.

[0051] The electrode plate 7 falls from the discharge end of the front chain conveyor 201 onto the vertical receiving plate 403 for stacking. When the number of plates reaches 30 as specified in the program, the electric screw linear slide module 401 drives the vertical receiving plate 403 to descend rapidly, and the stacked electrode plate 7 falls onto the rear chain conveyor 301 for transfer to the next process.

[0052] As the vertical receiving plate 403 descends rapidly, electrode plates 7 continuously fall from the discharge end of the front chain conveyor 201. At this time, driven by the first cylinder 502 and the second cylinder 504, the horizontal receiving plate 506 quickly takes over from the vertical receiving plate 403 to receive the continuously falling electrode plates 7. When the horizontal receiving plate 506 has received 10 electrode plates 7, the vertical receiving plate 403 rises to take over the receiving action, and the electrode plates 7 stacked on the horizontal receiving plate 506 fall onto the vertical receiving plate 403. However, the number of electrode plates 7 on the vertical receiving plate 403 has not reached the 30 plates specified in the program, and the vertical receiving plate 403 continues to receive electrode plates 7. When the number of plates on the vertical receiving plate 403 reaches 30, the vertical receiving plate 403 descends rapidly, and the stacked electrode plates 7 fall onto the rear chain conveyor 301; the horizontal receiving plate 506 quickly takes over from the vertical receiving plate 403 to receive the electrode plates 7, and this cycle repeats.

[0053] The above embodiments are only for illustrating the technical concept and features of the present invention, and are intended to enable those skilled in the art to understand the content of the present invention and implement it accordingly. They should not be construed as limiting the scope of protection of the present invention. All equivalent transformations or modifications made in accordance with the spirit and essence of the present invention should be covered within the scope of protection of the present invention.
