焊接机器人应用于机械制造产业，其中在汽车制造业应用的较为普遍。焊接机器人的控制系统可以实现自动焊接，智能控制系统就和人的大脑一样，可以下达指令来完成一系列的操作，控制系统可以对焊缝智能识别，根据焊缝的规格做出反应，选择合适的焊接参数相匹配，保证焊接的稳定性。那么，怎样选择合适的焊接机器人呢？
Welding robots are used in mechanical manufacturing industry, especially in automobile manufacturing industry. The control system of the welding robot can realize automatic welding. The intelligent control system, just like the human brain, can issue instructions to complete a series of operations. The control system can intelligently identify the weld, react according to the weld specifications, select appropriate welding parameters to match, and ensure the stability of welding. So, how to choose the right welding robot?
1.机器人通用技术指标
General technical indicators of robot
①判断焊接机器人灵活性的重要指标是自由度数。一般而言，在机器人工作空间中可以到达3个自由度，但是焊接不仅必须到达空间中的某个位置，而且还必须确保焊枪的空间姿势。因此，电弧焊和切割机器人至少需要5个自由度，点焊机器人至少需要6个自由度。
The degree of freedom is an important index to judge the flexibility of welding robot. Generally speaking, three degrees of freedom can be reached in the robot workspace, but welding must not only reach a certain position in the space, but also ensure the spatial posture of the welding gun. Therefore, arc welding and cutting robots need at least 5 degrees of freedom, and spot welding robots need at least 6 degrees of freedom.
②负载是指机器人末端可以承受的额定负载。焊枪及其电缆，切割工具和煤气管，焊钳和电缆以及冷却水管都是负载。因此，电弧焊和切割机器人的负载能力为6-10kg。如果点焊机器人使用集成变压器和集成焊钳，则其负载能力应为6090kg。如果使用单独的焊钳，其负载能力应为4050kg。
The load refers to the rated load that the robot end can bear. The welding gun and its cables, cutting tools and gas pipes, welding tongs and cables, and cooling water pipes are all loads. Therefore, the load capacity of arc welding and cutting robots is 6-10kg. If the spot welding robot uses integrated transformer and integrated welding tongs, its load capacity shall be 6090kg. If a separate welding tongs is used, its load capacity shall be 4050kg.
工作空间制造商给定的工作空间是机器人在没有任何终端操纵器的情况下可达到的最大空间，该空间由图形表示。安装焊炬后，应特别注意焊炬的姿势。实际可焊接空间将比制造商提供的空间小一层。有必要用比例图法或模型法仔细计算以确定其是否满足实际需要。
Workspace The workspace given by the manufacturer is the maximum space that the robot can reach without any terminal manipulator, and this space is represented by a graph. After installing the torch, pay special attention to the position of the torch. The actual weldable space will be one floor less than the space provided by the manufacturer. It is necessary to calculate carefully with scale drawing method or model method to determine whether it meets the actual needs.
2.焊接机器人的特殊技术指标
Special technical indicators of welding robot
①适用的焊接或切割方法这对于弧焊机器人特别重要。这实质上反映了机器人控制和驱动系统的抗干扰能力。目前，一般的弧焊机器人只使用MIG焊接方法，因为这些焊接方法不需要使用高频电弧点火，机器人的控制和驱动系统没有特殊的抗干扰措施，可以使用钨极氩弧焊焊接。该机器人是近年来的新产品，它具有一套特殊的抗干扰措施。选择机器人时应注意这一点。
Suitable welding or cutting methods This is particularly important for arc welding robots. This essentially reflects the anti-interference ability of the robot control and drive system. At present, the general arc welding robot only uses MIG welding methods, because these welding methods do not need to use high-frequency arc ignition, and the robot control and drive system has no special anti-interference measures, and can use argon tungsten arc welding. The robot is a new product in recent years, which has a set of special anti-interference measures. This should be noted when selecting robots.
②摆动功能这对于弧焊机器人非常重要，它与弧焊机器人的工艺性能有关。目前，电弧焊机器人的摆动功能已经非常不同。有些机器人只有几种固定的摆动模式，有些机器人只能在xy平面上任意设置摆动模式和参数。最佳选择是能够在空间中移动。在该范围内任意设置摆动模式和参数。
Swing function is very important for arc welding robot, which is related to the process performance of arc welding robot. At present, the swing function of arc welding robot is very different. Some robots only have several fixed swing modes, and some robots can only set swing modes and parameters arbitrarily on the xy plane. The best choice is to be able to move in space. Set the swing mode and parameters arbitrarily within this range.
③焊接用户点示教功能这是在焊接示教中非常有用的功能，即在进行焊接示教时，首先示教焊缝上某个点的位置，然后调节焊枪或焊钳的姿势。调整姿势时，原始示教点的位置完全不变。实际上，机器人可以自动补偿由于姿势的调整而导致的住家点的位置变化，并确保住家点的坐标以方便教学操作者。
Welding user point teaching function This is a very useful function in welding teaching, that is, when teaching welding, first teach the position of a point on the weld, and then adjust the position of the welding gun or welding tongs. When adjusting the posture, the position of the original teaching point is completely unchanged. In fact, the robot can automatically compensate the position change of the home point caused by the posture adjustment, and ensure the coordinates of the home point to facilitate the teaching operator.
