For transformers with small capacity, 50Hz power frequency AC can be used, while for transformers with large capacity, inverter technology has been used to change 50Hz power frequency AC into 600 ~ 700Hz AC, so as to reduce and reduce the volume of transformers. After voltage transformation, 600 ~ 700Hz AC welding can be directly used, or secondary rectification can be carried out and DC welding can be used. The welding parameters are adjusted by the timer, see Figure 1b. The new timer has been computerized, so the robot control cabinet can directly control the timer without additional interface. The welding tongs of spot welding robot usually use pneumatic welding tongs. The opening between the two electrodes of pneumatic welding tongs is generally only two-stage stroke. Moreover, once the electrode pressure is set, it cannot be changed at will. In recent years, a new type of electric servo spot welding clamp has emerged. The opening and closing of the welding clamp are driven by the servo motor and fed back by the code disk, so that the opening degree of the welding clamp can be arbitrarily selected and preset according to the actual needs. Moreover, the pressing force between electrodes can also be adjusted steplessly. The welding equipment of the welding robot adopts an integrated welding clamp, and the welding transformer is installed behind the welding clamp, so the transformer shall be miniaturized as far as possible. Automatic welding equipment.

自动焊接机器人的优点

Advantages of automatic welding robot

1、机器人焊接可以提高产品质量

1. Robot welding can improve product quality

焊接机器人在焊接过程中，只要给出焊接参数，和运动轨迹，机器人就会准确重复此动作，焊接参数如焊接电流、电压、焊接速度及焊接焊丝长度等对焊接结果起决定作用。采用机器人焊接时对于每条焊缝的焊接参数都是恒定的，焊缝质量受人的因素影响较小，降低了对工人操作技术的要求，因此焊接质量是稳定的，从而保证了我们产品的质量。而人工焊接时，焊接速度、焊丝伸长等都是变化的，因此很难做到质量的均一性。全自动焊接设备。

In the welding process, as long as the welding parameters and motion trajectory are given, the robot will accurately repeat this action. The welding parameters such as welding current, voltage, welding speed and welding wire length play a decisive role in the welding results. When robot welding is adopted, the welding parameters of each weld are constant, and the weld quality is less affected by human factors, which reduces the requirements for workers' operation technology. Therefore, the welding quality is stable, so as to ensure the quality of our products. In manual welding, the welding speed and wire elongation change, so it is difficult to achieve the uniformity of quality. Automatic welding equipment.

2、机器人焊接可以提高生产效率

2. Robot welding can improve production efficiency

焊接机器人响应时间短，动作迅速，焊接速度在60-3000px/分钟，这个速度远远高于手工焊接，机器人在运转过程中不停顿也不休息，但是工人上班时是不可能做到不停顿不休息，同时工人的工作效率也受到心情等因素影响，工人会请假、发呆、聊天、抽烟、上厕所，加班要给加班工资，而机器人就没有上述问题，只要保证外部水电气等条件，就可以持续工作，这就无形中提高了企业的生产效率。

The welding robot has short response time and rapid action. The welding speed is 60-3000px / min, which is much higher than that of manual welding. The robot does not stop or rest during operation, but it is impossible for workers to stop and rest at work. At the same time, the working efficiency of workers is also affected by mood and other factors. Workers will ask for leave, daze, chat, smoke and go to the toilet. Overtime pay is required for overtime, The robot does not have the above problems. As long as the external water, electricity and other conditions are guaranteed, it can continue to work, which virtually improves the production efficiency of the enterprise.

3、机器人焊接容易安排生产计划

3. Robot welding is easy to arrange production plan

由于机器人可重复性高，只要给定参数，就会永远按照指令去动作，因此机器人焊接产品周期明确，容易控制产品产量。机器人的生产节拍是固定的，因此安排生产计划十分明确。准确的生产计划可应使企业的生产效率、资源的综合利用做到更大化。

Due to the high repeatability of the robot, as long as the parameters are given, it will always act according to the instructions. Therefore, the robot welding product cycle is clear and it is easy to control the product output. The production rhythm of the robot is fixed, so the production plan is very clear. Accurate production planning can make the production efficiency of enterprises and the comprehensive utilization of resources greater.

4、机器人焊接可以降低企业成本

4. Robot welding can reduce the cost of enterprises

焊接机器人降低企业成本主要体现在规模化生产中，一台机器人可以替代2到4名产业工人，根据企业具体情况，有所不同。机器人没有疲劳，可24小时连续生产，另外随着高速焊接技术的应用，使用机器人焊接，成本降低的更加明显。

The reduction of enterprise cost by welding robot is mainly reflected in large-scale production. One robot can replace 2 to 4 industrial workers, which is different according to the specific situation of the enterprise. The robot has no fatigue and can produce continuously 24 hours a day. In addition, with the application of high-speed welding technology, the cost of robot welding is reduced more obviously.
