Automatic welding robot is more common and used more frequently in our life. However, in the process of using, we will encounter various problems, so you need to understand the characteristics of automatic welding machine system. Structural features of automatic welding machine system:

1.機械

1. Machinery

自動焊接機的系統由三部分組成：機械裝置，電源裝置和控制裝置。為滿足焊接工藝要求，增壓機構(焊鉗)采用雙沖程氣動快速傳遞機構?？梢酝ㄟ^改變行程控制手柄來改變焊鉗的開度。它可以分為大孔徑和小孔徑，以滿足焊接操作的要求。正常狀態是焊鉗打開一小段行程。當控制按鈕切換到“開”位置時，通過按下手柄上的開關將夾具夾緊并加壓。同時，在控制系統的控制下完成焊接循環后，電流將返回短行程。

The system of automatic welding machine consists of three parts: mechanical device, power supply device and control device. In order to meet the requirements of welding process, the supercharging mechanism (welding tongs) adopts double stroke pneumatic fast transfer mechanism. The opening of welding tongs can be changed by changing the stroke control handle. It can be divided into large aperture and small aperture to meet the requirements of welding operation. The normal state is that the welding tongs are opened for a short distance. When the control button is switched to the "on" position, the clamp is clamped and pressurized by pressing the switch on the handle. At the same time, after the welding cycle is completed under the control of the control system, the current will return to the short stroke.

2.電源裝置

2. Power supply device

主電源電路由電阻焊接變壓器，晶閘管單元，主電源開關，焊接電路等組成。目前，我們使用的焊接設備是單相工業頻率交流電阻焊接機，功率為200kVA，二次輸出電壓為20V。由于生產了多個串聯模型，焊鉗要焊接高強度鋼板和低碳鋼板，并且焊鉗的槍臂要傳遞較大的機械力和電流。因此，焊鉗的強度，剛度和發熱要滿足一定的要求。并且要具有良好的導電性和導熱性。同時，焊鉗要用水冷卻。因此，選擇了可以承受400kg壓力的新型焊鉗。

The main power circuit is composed of resistance welding transformer, thyristor unit, main power switch and welding circuit. At present, the welding equipment we use is single-phase industrial frequency AC resistance welding machine, with power of 200KVA and secondary output voltage of 20V. Due to the production of multiple series models, the welding tongs need to weld high-strength steel plate and low-carbon steel plate, and the gun arm of the welding tongs needs to transfer large mechanical force and current. Therefore, the strength, rigidity and heating of welding tongs should meet certain requirements. And it should have good conductivity and thermal conductivity. At the same time, the welding tongs should be cooled with water. Therefore, a new type of welding tongs which can bear 400kg pressure is selected.

3.控制裝置

3. Control device

該控制裝置主要提供信號，以控制電阻焊機的動作，以接通和斷開焊接電流，控制焊接電流的值，并進行故障監視和處理。

The control device mainly provides signals to control the action of resistance welding machine, to connect and disconnect welding current, to control the value of welding current, and to monitor and deal with faults.

簡而言之，自動焊接機轉盤式超聲波自動焊接，與傳統的振動摩擦焊接和熱熔焊接相比，超聲焊接更具有快速，通常在二次清洗中完成焊接，因為不使用助焊劑，大大降低了污染的風險，從而提高了產品質量;了因使用助焊劑，浪費率低和可重復處理而造成的成本，自動焊接機設備適用于批量生產和自動化生產環境。

In short, compared with the traditional vibration friction welding and hot melt welding, the rotary table type ultrasonic automatic welding of automatic welding machine is faster, and the welding is usually completed in the secondary cleaning, because no flux is used, which greatly reduces the risk of pollution and improves the product quality; The automatic welding machine is suitable for mass production and automatic production environment.
