介绍两种焊接机器人所常用的传感器原理。一、机械作用的原理机械式传感器系统有三种基本类型:传感器和焊枪刚性固定在一起;传感器和焊枪通过弹簧或传动机构相互联接,由传感器所形成的电信号来调节焊枪的位置。这些系统的优点是价格低,其缺点是对焊缝和工件有一定的几何形状要求,常受接 Describes the sensor principles commonly used in two welding robots. First, the principle of mechanical action Mechanical sensor system has three basic types: the sensor and the welding torch rigidly fixed together; sensors and welding torch through the spring or transmission mechanism connected to each other, the sensor formed by the electrical signal to adjust the position of the torch. These systems have the advantage of low prices, the disadvantage is that the welding seam and the workpiece has a certain geometric requirements, often by the access
