Description

Technical Field

[0001] The invention belongs to the technical field of lead-acid battery processing equipment, in particular to an automatic weighing device for lead-acid battery pole groups. Background Art

[0002] Lead-acid batteries are a widely used chemical power source. One of their core components is the electrode group, which is assembled in a certain order and quantity from positive plates, negative plates, and separators. It is the main site for the electrochemical reaction of the battery. The production process of the electrode group mainly includes the following key steps:

[0003] Plate manufacturing: The plate is the basic unit of the electrode group and is divided into positive and negative plates. The manufacturing of the plate usually includes processes such as lead powder preparation, paste mixing, plate coating, curing, and drying. Through these processes, lead powder, dilute sulfuric acid and additives are mixed to form lead paste, which is evenly coated on the grid to form a plate with a certain thickness and density.

[0004] Pole group assembly: The manufactured positive and negative plates are arranged alternately with separators in the specified quantity and order to assemble into pole groups. The function of the separator is to prevent the positive and negative plates from direct contact and short circuit, while allowing ions in the electrolyte to pass through to ensure normal charging and discharging of the battery.

[0005] Inserting the electrode group into the battery shell and welding: Place the assembled electrode group into the battery shell, and weld the positive and negative plates together through the busbar to form the positive and negative terminal of the battery.

[0006] Electrolyte injection and formation: Inject electrolyte into the battery shell and perform formation treatment. Formation is an important step in the battery manufacturing process. Through the charge and discharge process, the active substances on the plates undergo electrochemical reactions to form a stable electrode structure, thereby improving the performance of the battery.

[0007] In the production process of lead-acid batteries, the packing process is a key link and plays a vital role in the quality of the final product. However, in the actual production process, the pole groups produced by this process occasionally have some problems that cannot be ignored. The main manifestations are inaccurate number of pole pieces in the pole group, the presence of multiple or insufficient pole pieces, and large deviation in the overall weight of the pole group. The multiple pole piece phenomenon means that the number of pole pieces in the pole group exceeds the specified standard, which may cause the internal structure of the battery to be too tight, and the penetration and diffusion of the electrolyte to be hindered, affecting the battery's charge and discharge performance and cycle life; insufficient pole pieces will result in insufficient active substances in the pole group, reduced battery capacity, and unable to meet normal usage needs. The large deviation in the pole group weight will also destroy the balance of the electrochemical reaction inside the battery, making the battery performance unstable and the consistency poor.

[0008] Therefore, an automatic weighing device for lead-acid battery pole groups is proposed to ensure that the produced pole groups meet relevant standards and customer requirements and improve the market competitiveness of the products. Summary of the Invention

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] like Figures 1 to 5As shown, the present invention provides an automatic weighing device for lead-acid battery pole groups, including a battery automatic sheet wrapping equipment conveyor belt 8, and a structural member of the automatic weighing device for the pole group is arranged below the battery automatic sheet wrapping equipment conveyor belt 8. The structural member of the automatic weighing device for the pole group includes a base 1, a plurality of mounting support frames 2 and a top plate 6. The base 1 is located at the bottom, and the plurality of mounting support frames 2 are all located between the base 1 and the top plate 6 and are fixedly connected to the base 1 and the top plate 6 respectively. A hydraulic cylinder 3 is fixedly installed on the top of the base 1, and a weighing sensor 4 is provided on the output shaft of the hydraulic cylinder 3. A structural member 5 for pole group weighing is fixedly installed on the top of the weighing sensor 4; a lifting speed adjusting component 7 is provided on the outer wall of the hydraulic cylinder 3, and the lifting speed adjusting component 7 is located at the top of the outer wall of the lifting speed adjusting component 7; the base 1 and the mounting support frame 2 are both rectangular in design, and the length of the base 1 and the mounting support frame 2 is 1 / 4 of the base 1 and the mounting support frame 2. , and completely overlap in the vertical direction; several mounting support frames 2 are designed to be distributed in a rectangular shape, and several mounting support frames 2 are respectively arranged at the top corners of the base 1 and the mounting support frame 2; the conveyor belt 8 of the battery automatic wrapping equipment is in a pulsating step-by-step operation, and the conveyor belt is made of high-strength rubber material with a special anti-slip texture on the surface; the lifting speed adjustment component 7 is composed of a regulating valve and a connecting pipe, the regulating valve is made of brass, and the connecting pipe is made of a high-pressure rubber hose; the structural member 5 of the pole group weighing is made of lightweight aluminum alloy and is made by an extrusion molding process; the weighing sensor 4 adopts a high-precision strain gauge sensor, and the outer shell is made of stainless steel; the cylinder body of the hydraulic cylinder 3 is integrally formed of high-strength cast iron material, and its outer wall is rust-proofed; several mounting support frames 2 are made of high-quality carbon structural steel that has been quenched and tempered, and the shape is a slender cylinder.

[0030] Through the coordinated design of the above-mentioned overall device, efficient and accurate automatic weighing of lead-acid battery pole groups in the production process is achieved; the conveyor belt 8 of the battery automatic sheet wrapping equipment operates in a pulsating step-by-step manner, and accurately and orderly conveys the wrapped pole groups to the top of the weighing device; when the pole group reaches the specified position, the hydraulic cylinder 3 starts working under the instruction of the control system, and its output shaft pushes the weighing sensor 4 and the pole group weighing structure 5 to rise, so that the pole group is smoothly transferred from the conveyor belt to the pole group weighing structure 5; the weighing sensor 4 senses the weight change of the pole group in real time and transmits the data to the control system for analysis and processing; in this process, the various components work closely together to ensure the accuracy and timeliness of the weighing operation, greatly improve production efficiency, reduce errors caused by manual intervention, and provide a reliable basis for subsequent product quality control;

[0031] Both the base 1 and the mounting support frame 2 are rectangular in design, with identical length and width values ​​and complete vertical overlap. This precise geometric coordination ensures extremely high stability for the entire weighing device structure. The base 1, serving as the foundational support, is integrally molded from high-strength alloy steel, providing a solid load-bearing platform for the components above. The mounting support frame 2 is made of high-quality, quenched and tempered carbon structural steel in a slender cylindrical shape, securely connected to the base 1 and top plate 6 through precise welding. This design not only effectively disperses and withstands the various forces generated during weighing, preventing structural deformation, but also ensures the stability of the hydraulic cylinder 3 during lifting and lowering, ensuring that the load cell 4 can accurately obtain extreme group weight data, thereby improving weighing accuracy and reliability.

[0032] The cylinder body of the hydraulic cylinder 3 is made of high-strength cast iron material in one piece, which has excellent strength and sealing, and can provide stable and powerful power for the lifting of the pole group; its outer wall has been treated with rust prevention, which extends its service life in a humid production environment; the lifting speed adjustment component 7 on the outer wall of the hydraulic cylinder 3 is composed of a regulating valve and a connecting pipe. The regulating valve is made of brass material with good wear resistance and corrosion resistance, and the connecting pipe is made of high-pressure rubber hose with good flexibility and strong sealing; through the regulating valve, the operator can accurately control the flow of hydraulic oil according to actual production needs, and then adjust the lifting speed of the output shaft of the hydraulic cylinder 3; this combination enables the pole group to be lifted smoothly and slowly, avoiding the problem of pole group shaking or inaccurate weighing data caused by excessive speed, and ensuring the stability and accuracy of the weighing process;

[0033] The weighing sensor 4 adopts a high-precision strain gauge sensor, whose sensitive element can accurately sense tiny weight changes. The shell is made of stainless steel, which has good corrosion resistance and wear resistance, and effectively protects the internal components of the sensor. The structural member 5 for the pole group weighing is made of lightweight aluminum alloy and is made by an extrusion molding process. It has the characteristics of light weight and high strength. Its flat square tray-like structure is convenient for placing and removing the pole group, and its smooth surface will not cause damage to the pole group. When the pole group is placed on the structural member 5 for the pole group weighing, it is evenly transmitted to the weighing sensor 4. The sensor converts the weight signal into an electrical signal and transmits it to the control system. This combination enables the weighing process to be completed quickly and accurately, while reducing the influence of the weight and deformation of the structural member itself on the weighing result, thereby improving the accuracy and reliability of weighing.

[0034] The conveyor belt 8 of the automatic battery sheet wrapping equipment is made of high-strength rubber material with a special anti-slip texture on the surface, which can effectively prevent the pole group from sliding during transportation and ensure that the pole group can be accurately and stably transported to the top of the weighing device; the pulsating stepping operation mode enables the conveyor belt to deliver the pole group to the designated weighing position according to a fixed rhythm and position, perfectly coordinating with the lifting and lowering action of the weighing device; when the pole group reaches the weighing position, the conveyor belt stops running and the hydraulic cylinder 3 starts working to perform the weighing operation; after the weighing is completed, the conveyor belt continues to run and transports the weighed pole group to the next process; this coordination realizes the automation and continuity of the production process, improves production efficiency, reduces the time and error of manual operation, and also ensures the accuracy and consistency of the weighing operation;

[0035] The careful selection of materials for each component further enhances the performance and effect of the overall device; the base 1 and the mounting support frame 2 are made of high-strength alloy steel and high-quality carbon structural steel to ensure the stability and load-bearing capacity of the device; the high-strength cast iron material and rust-proof treatment of the hydraulic cylinder 3 ensure the stability and durability of the power output; the brass regulating valve and high-pressure rubber hose connecting pipeline of the lifting speed adjustment component 7 improve the accuracy and reliability of the adjustment; the stainless steel shell and high-precision strain gauge of the weighing sensor 4 ensure the accuracy and anti-interference ability of weighing; the lightweight aluminum alloy material of the pole group weighing structural member 5 reduces the weight of the device while ensuring sufficient strength, so that the entire lead-acid battery pole group automatic weighing device can operate stably for a long time in harsh production environments, greatly improving product quality and production efficiency and reducing production costs.

[0036] The working principle and use process of the present invention:

[0037] The operator starts the lead-acid battery pole group automatic weighing device, and the control system performs an initialization check on each component to ensure that the battery automatic sheet packaging equipment conveyor belt 8, hydraulic cylinder 3, weighing sensor 4, lifting speed adjustment component 7 and other components are in normal working condition;

[0038] According to actual production needs, the operator sets relevant parameters through the control system, such as the lifting speed of the hydraulic cylinder 3 and the weighing accuracy threshold. By adjusting the regulating valve of the lifting speed regulating component 7, the flow rate of the hydraulic oil is controlled, thereby setting the lifting speed of the output shaft of the hydraulic cylinder 3.

[0039] The electrode groups enter the conveyor belt: The electrode groups that have completed the packaging in the battery automatic packaging equipment are placed on the conveyor belt 8 of the battery automatic packaging equipment; the conveyor belt is made of high-strength rubber material with a special anti-slip texture on the surface, which can effectively prevent the electrode groups from sliding during transportation;

[0040] The conveyor belt operates in a pulsating step-by-step manner, transporting the electrode group forward at a fixed rhythm and position. This mode of operation can accurately control the conveying position of the electrode group, ensuring that the electrode group can accurately reach the designated position above the weighing device.

[0041] The pole group arrives at the weighing position: When the pole group moves with the conveyor belt to the top of the weighing device, the conveyor belt stops running and the pole group stays above the weighing position, waiting for the next weighing operation;

[0042] After receiving the signal of the arrival of the pole group, the control system sends a start command to the hydraulic cylinder 3, and the hydraulic cylinder 3 begins to prepare for work. Its output shaft is in a standby state, ready to push the weighing sensor 4 and the pole group weighing structure 5 up;

[0043] The output shaft of the hydraulic cylinder 3 extends upward, pushing the load cell 4 and the pole group weighing structure 5 to rise steadily; the pole group weighing structure 5 is made of lightweight aluminum alloy through an extrusion molding process. Its flat square tray-like structure can smoothly receive the pole group falling from the conveyor belt;

[0044] After the pole group is placed on the pole group weighing structure 5, the weight is evenly transferred to the weighing sensor 4; the weighing sensor 4 uses a high-precision strain gauge sensor, whose sensitive element can accurately sense tiny weight changes and convert the weight signal into an electrical signal;

[0045] Data transmission and analysis: The weighing sensor 4 transmits the collected electrical signal to the control system, which analyzes and processes the data to determine whether the weight of the pole group meets the standard requirements; at the same time, the weighing data is recorded for subsequent quality traceability and production statistics;

[0046] After weighing is completed, the output shaft of the hydraulic cylinder 3 descends, and the electrode group weighing structure 5 brings the electrode group back to its initial position; the battery automatic packaging equipment conveyor belt 8 continues to operate in a pulsating step-by-step manner, conveying the weighed electrode group to the next process, such as electrode group shelling, welding, etc.

[0047] If the weight of the pole group is found to be inconsistent with the standard during the weighing process, the control system will issue an alarm, prompting the operator to intervene manually to inspect and handle the abnormal pole group to ensure product quality;

[0048] The entire device operates in a cycle according to the above-mentioned work flow, and continuously weighs the electrode groups transported on the conveyor belt 8 of the automatic battery packaging equipment, thereby realizing the automation and continuity of the production process and improving production efficiency and product quality.
