This leads to the inability to directly use rivet guns in some connection processes that require high precision, and instead, methods such as laser welding must be used to complete the fusion welding or sealing between two parts, such as in the sealing of battery injection holes and explosion-proof valve welding in the production process of power batteries.
Although laser welding has a high degree of maturity and advantages, high temperatures are generated during the laser welding process. The metal surface is heated to a high temperature, causing the material to reach the boiling point and vaporize. At this time, the laser energy is transferred from the metal surface to the inside of the metal to form a molten pool. When the molten pool is close to the sealing member, there is a risk of the sealing member being instantaneously vaporized locally, and the internal pressure of the battery is ejected upward along the axis, which may lead to the risk of battery cracks or explosions.
To address precision and safety requirements in welding processes such as sealing battery injection holes, which are extremely high, Robustmotion has been deeply involved in the front line of lithium battery production for a long time, and has jointly developed with the world's leading battery manufacturers. After multiple iterations and production line verifications, SoftForce® electric rivet gun suitable for fully automatic equipment on the production line has been introduced.
Dare to challenge industry pain points and break through industry limits!
SoftForce® electric rivet gun can be flexibly installed on production line equipment according to the needs of the work, and with a visual system, a single mechanism can achieve a series of continuous actions such as fully automatic rivet feeding, pre-tightening, riveting, and nail retraction, without the need for manual operation, greatly reducing the impact of unstable manual operation factors and labor costs.
This rivet gun is equipped with Robustmotion's unique SoftForce® precision force control technology and efficient algorithms. The integrated drive control system is fully integrated inside the mechanism, using an efficient direct drive motor to drive, which can, like a human hand, achieve precise and minimal damage pre-tightening of the rivet, accurately positioned in the rivet hole, and then break the rivet with a huge instantaneous output, and finally retract the broken rivet. The maximum instantaneous output when breaking can reach several thousand Newtons.
While ensuring a large dynamic output range, the control of force is precise and stable, ensuring that the rivet action is well completed, the rivet is not deformed, the sealing is good, and the consistency is good.
The product has high rigidity, the overall structure is compact, the space occupation of the equipment is minimized, and the installation is simple, suitable for various production line equipment; the gun body is made of high-quality alloy steel, and the gun body after heat treatment has higher hardness and durability; the riveting head is made of high-carbon steel, which is more wear-resistant and not easy to deform.
At the same time, the product supports multiple control methods and bus protocols, which can maintain synchronization and consistency with PLCs, visual systems, and other equipment, and can monitor force, position, and speed data in real-time, with a beat efficiency far higher than laser welding.
This patented riveting process technology is suitable for key processes in the production of power batteries, such as sealing battery injection holes, which not only reduces variables in the battery production process, makes the production process safer, ensures the sealing of the battery, and improves the stability and safety and reliability of battery production, but also simplifies the sealing process of the battery injection port, effectively reducing the overall manufacturing cost of the battery. In the manufacturing process of power batteries and other industrial automated production lines, it further meets the technical process and intelligent equipment needs of enterprises for low cost, high quality, and high efficiency.
