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.

自動焊接機器人的優點

Advantages of automatic welding robot

1、機器人焊接可以提高產品質量

1. Robot welding can improve product quality

焊接機器人在焊接過程中，只要給出焊接參數，和運動軌跡，機器人就會準確重復此動作，焊接參數如焊接電流、電壓、焊接速度及焊接焊絲長度等對焊接結果起決定作用。采用機器人焊接時對于每條焊縫的焊接參數都是恒定的，焊縫質量受人的因素影響較小，降低了對工人操作技術的要求，因此焊接質量是穩定的，從而保證了我們產品的質量。而人工焊接時，焊接速度、焊絲伸長等都是變化的，因此很難做到質量的均一性。全自動焊接設備。

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、機器人焊接可以提高生產效率

2. Robot welding can improve production efficiency

焊接機器人響應時間短，動作迅速，焊接速度在60-3000px/分鐘，這個速度遠遠高于手工焊接，機器人在運轉過程中不停頓也不休息，但是工人上班時是不可能做到不停頓不休息，同時工人的工作效率也受到心情等因素影響，工人會請假、發呆、聊天、抽煙、上廁所，加班要給加班工資，而機器人就沒有上述問題，只要保證外部水電氣等條件，就可以持續工作，這就無形中提高了企業的生產效率。

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、機器人焊接容易安排生產計劃

3. Robot welding is easy to arrange production plan

由于機器人可重復性高，只要給定參數，就會永遠按照指令去動作，因此機器人焊接產品周期明確，容易控制產品產量。機器人的生產節拍是固定的，因此安排生產計劃十分明確。準確的生產計劃可應使企業的生產效率、資源的綜合利用做到更大化。

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、機器人焊接可以降低企業成本

4. Robot welding can reduce the cost of enterprises

焊接機器人降低企業成本主要體現在規?；a中，一臺機器人可以替代2到4名產業工人，根據企業具體情況，有所不同。機器人沒有疲勞，可24小時連續生產，另外隨著高速焊接技術的應用，使用機器人焊接，成本降低的更加明顯。

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.
