机器人螺柱焊解决方案
机器人螺柱焊是一种高效的连接工艺，可在一个快速工序中将螺纹螺柱、销钉或紧固件焊接到金属表面。该工艺能够实现牢固且可重复的连接，无需钻孔、攻丝或额外的机械紧固。
在自动化生产环境中，螺柱焊需要精确定位、稳定传输高焊接电流以及可靠的机械线缆和管路布置。极短的焊接周期与机器人动态运动相结合，对整个机器人系统提出了很高要求。
BizLink 为制造商提供集成机器人解决方案，有助于提升螺柱焊应用中的定位精度、电气稳定性和系统长期可靠性。
什么是机器人螺柱焊？
螺柱焊是一种将金属螺柱通过电弧法或电容放电法焊接到基材上的工艺。在这一过程中，螺柱端部和基材会被短暂熔化，并在受控压力下熔合在一起。
其结果是在整个螺柱截面上形成焊接连接，具有高机械强度、变形小且无需从背面进行操作。
机器人螺柱焊工艺的工作原理
该工艺通常包括：
- 将螺柱定位在工件上
- 引燃短时电弧或触发电容放电
- 熔化螺柱端部和基材
- 施加规定的压力以形成焊接连接
- 在毫秒内快速凝固
由于焊接周期极短，螺柱焊特别适合自动化生产和大批量制造。
常见螺柱焊方法
拉弧式螺柱焊
适用于较大尺寸的螺柱以及对焊接强度要求较高的高负载应用。
电容放电式（CD）螺柱焊
放电时间极短、整体热输入低，非常适合薄板材料和精密应用。
这两种方法都需要精确定位和稳定的能量传输，以确保焊接连接的一致成形。
机器人螺柱焊为何是现代制造不可或缺的工艺
固定点的高重复精度
机器人以高重复精度将螺柱焊接头定位到预定义坐标。然而，实际的螺柱定位精度取决于稳定的工具定位以及受控的机械线缆和管路布置。
即使是很小的位置偏差，也可能导致螺柱偏心或熔合不足。
High-Flex Welding and Control Cables
BizLink cables are designed for high current peaks and continuous robotic motion. Optimized conductor design and durable insulation ensure stable energy transmission and long service life under dynamic load.
Engineered Dresspack Systems
In robotic stud welding, extremely short weld cycles and high current peaks are combined with rapid mechanical movement and plunge motion. This creates dynamic stress on cables and routing systems.
BizLink dresspack solutions guide cables in defined paths, reducing torsion, absorbing mechanical shock and minimizing stress caused by repetitive motion. Controlled routing supports stable energy and signal transmission, helping to maintain consistent weld timing and process reliability.
This extends the lifetime of cables and robot components while ensuring stable performance in high-cycle stud welding applications.
BizLink advintec TCP Tool Measurement
In robotic stud welding, precise positioning of the welding tool is critical to ensure correct arc initiation, consistent fusion and accurate stud placement. Even small deviations can affect weld formation, alignment and joint strength.
BizLink advintec TCP enables automated and highly precise verification of the robot’s tool center point (TCP) directly within the production environment.
The system is independent of the specific application and primarily depends on the geometry of the robot tool. Rotation-symmetric tools can be calibrated particularly easily. Even complex or indirectly measurable stud welding tools can be referenced using auxiliary pins or defined reference components.
By compensating measured deviations directly within the robot program, advintec TCP ensures consistent stud positioning, supports stable lift and plunge behavior and enhances process reliability in high-cycle stud welding applications.
careDP – AI-Powered Condition Monitoring
In robotic stud welding, extremely short cycle times, rapid tool movement and repeated plunge motion create continuous mechanical stress on cables and routing systems. Over time, this can lead to wear, signal instability or unexpected failures.
careDP continuously analyzes robotic dresspack behavior and detects early signs of abnormal motion patterns or stress development.
By enabling predictive maintenance, it helps prevent unplanned downtime that could interrupt fastening operations and affect production throughput.
By combining calibration accuracy, durable cable management systems and intelligent monitoring, BizLink supports consistent stud placement, reduces process interruptions and enhances long-term reliability in high-cycle stud welding environments.
