Description

Technical Field

[0001] The present invention relates to the field of battery production equipment, and in particular to an automatic assembly line for battery steel shells. Background Art

[0002] Batteries are an indispensable power source in daily life and industrial production, and the demand and application scenarios are very large. With the rapid development of the battery industry, production efficiency has gradually become one of the most important factors affecting the benefits of battery manufacturers. In addition, the structure, production accuracy and performance reliability of batteries are also key factors in determining whether battery manufacturers can have sustainable competitiveness and economic benefits. Therefore, improving the efficiency of production and processing while ensuring battery performance has become a problem that battery manufacturers must consider and improve in order to achieve sustainable development and improve industry competitiveness.

[0003] At present, in the production process of batteries, it is necessary to assemble and fix the battery steel shell and the parts installed thereon, including the outer insulating ring, the inner insulating ring, the pole and the pressure ring, etc. Among them, the pole is installed and fixed in the hole on the upper surface of the battery steel shell, the outer insulating ring is installed and matched with the pole from the outside of the battery steel shell, and the inner insulating ring and the pressure ring are installed and matched with the pole from the inside of the hollow structure at the other end of the battery steel shell. After all the parts are matched, each part needs to be fixed by riveting or other methods. Therefore, when assembling the battery steel shell, it is necessary to assemble the various parts in a certain order, and it is also necessary to consider the impact of the assembly order on production efficiency. Since the parts on the surface of the battery steel shell are divided into two types of external installation and internal installation, therefore, when assembling the battery steel shell in the prior art, it is usually first externally installed or internally installed, and then the battery steel shell is flipped 180 degrees before another part is installed. This assembly method greatly reduces the production efficiency because the battery steel shell needs to be flipped once more in the middle, and the installed parts are also prone to loosening or falling off during the flipping process, thereby affecting the quality and precision of the finished product, reducing the yield rate, increasing the cost of production and manufacturing, and increasing the loss of the enterprise. Therefore, it is necessary to optimize and design an automated assembly line for battery steel shells, while realizing the fully automated production of battery steel shell assembly, shortening the time spent on assembly of each part, and improving production and processing efficiency. In addition, it is also necessary to ensure that the performance and precision of the battery steel shell products meet the requirements, improve the yield rate of the battery steel shell products, and increase the reliability of the battery steel shell products.

[0004] Based on the problems existing in the above-mentioned prior art, the present invention provides an automatic assembly line for battery steel shells, which can realize the automatic assembly and processing of components on the battery steel shells, including the assembly and riveting of outer insulation rings, pole columns, inner insulation rings and pressing rings. Through the synchronous double-line assembly method and design, the present invention effectively improves the battery production and processing efficiency, and enhances the reliability and yield rate of battery products.

[0063] The following will further describe the battery steel shell automatic assembly line of the present invention in detail in combination with specific embodiments and the accompanying drawings

[0064] Refer to Figures 1 to 25, in a non-limiting embodiment of the present invention, an automatic assembly line for battery steel shells includes a feeding and transporting system 1, a double-line steel shell assembly system 3, a finished product inspection system 6, and a finished product discharging system 7 arranged in sequence:

[0065] The feeding and transporting system 1 includes a feeding and transporting wire rope 10. There are a feeding turning device 2 and a first transfer manipulator 81 between the feeding and transporting system 1 and the double-line steel shell assembly system 3. The feeding turning device 2 is located between the feeding and transporting wire rope 10 and the first transfer manipulator 81, and the first transfer manipulator 81 is located between the feeding turning device 2 and the double-line steel shell assembly system 3;

[0066] The double-line steel shell assembly system 3 includes a first turntable 31, a second turntable 32, and an assembly and processing system 4. The first turntable 31 is located on the side close to the feeding and transporting system 1, the second turntable 32 is located on the side close to the finished product inspection system 6. There is a second transfer manipulator 82 between the first turntable 31 and the second turntable 32. The assembly and processing system 4 is located on both sides of the first turntable 31 and the second turntable 32 different from the feeding and transporting system 1 and the finished product inspection system 6. There is a third transfer manipulator 83 between the second turntable 32 and the finished product inspection system 6;

[0067] There is a finished product picking manipulator 63 between the finished product inspection system 6 and the finished product discharging system 7. The finished product discharging system 7 includes a discharging and transporting wire rope 70. The finished product picking manipulator 63 makes a reciprocating picking and placing movement between the finished product inspection system 6 and the discharging and transporting wire rope 70.

[0068] In this preferred embodiment, specifically, an automatic assembly line for battery steel shells is provided. According to the processing and moving sequence of the steel shells, the automatic assembly line for battery steel shells is successively provided with a feeding and transporting system 1, a double-line assembly system 3 for steel shells, a finished product inspection system 6, and a finished product discharging system 7. First, the feeding and transporting system 1 includes a feeding transporting wire 10 for transporting the battery steel shells that need to be installed. Between the feeding and transporting system 1 and the double-line assembly system 3 for steel shells, there are successively arranged a feeding flipping device 2 and a first transfer manipulator 81. Since the opening of the battery steel shell faces upward when transported by the feeding transporting wire 10, in order to ensure that the battery steel shell can be smoothly fixed and installed on the fixture during subsequent processing, it is necessary to flip the battery steel shell through the feeding flipping device 2 so that its opening faces downward. The transfer manipulator can transfer the flipped battery steel shell to the first turntable 31 of the double-line assembly system 3 for steel shells. The double-line assembly system 3 for steel shells includes a first turntable 31 and a second turntable 32 arranged in sequence. The first turntable 31 is located on the side close to the feeding and conveying system, and the second turntable 32 is located on the side close to the finished product inspection system 6. Preferably, both the first turntable 31 and the second turntable 32 are provided with 8 stations. Also, according to specific situations, the specific number of stations can be adjusted. On both sides of the first turntable 31 and the second turntable 32 different from the feeding and transporting system 1 and the finished product inspection system 6, there is an assembly and processing system 4 for assembling and installing the battery steel shells and the components to be installed thereon. Since the installation of components on the battery steel shell is divided into external components and internal components, the external components need to be installed on the battery steel shell from the outside, and the internal components need to be installed from the inside. If the installation method in the prior art is used to install them sequentially, an additional flip of the battery steel shell is required in the middle, which greatly reduces the production efficiency, and the already installed components are also prone to loosen or fall off during the flipping process, affecting the quality of the finished product and further affecting the production and processing efficiency. In the double-line assembly system 3 for steel shells of the present invention, by providing the first turntable 31 and the second turntable 32, after the first transfer manipulator 81 transports the battery steel shell to the first turntable 31, the components for external installation on the battery steel shell are assembled on the first turntable 31. At this time, the second turntable 32 synchronously assembles the components for internal installation on the battery steel shell and installs them on the fixtures at each station of the second turntable 32.
