自動(dòng)焊接機(jī)器系統(tǒng)的結(jié)構(gòu)特性

自動(dòng)焊接機(jī)器人在我們的生活中更為常見,并且使用更加頻繁。但是,在使用過程中我們會(huì)遇到各種問題,因此您需要了解自動(dòng)焊接機(jī)器系統(tǒng)的特性。自動(dòng)焊機(jī)系統(tǒng)的結(jié)構(gòu)特點(diǎn):

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(jī)械
1. Machinery
自動(dòng)焊接機(jī)的系統(tǒng)由三部分組成:機(jī)械裝置,電源裝置和控制裝置。為滿足焊接工藝要求,增壓機(jī)構(gòu)(焊鉗)采用雙沖程氣動(dòng)快速傳遞機(jī)構(gòu)??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(tài)是焊鉗打開一小段行程。當(dāng)控制按鈕切換到“開”位置時(shí),通過按下手柄上的開關(guān)將夾具夾緊并加壓。同時(shí),在控制系統(tǒng)的控制下完成焊接循環(huán)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(guān),焊接電路等組成。目前,我們使用的焊接設(shè)備是單相工業(yè)頻率交流電阻焊接機(jī),功率為200kVA,二次輸出電壓為20V。由于生產(chǎn)了多個(gè)串聯(lián)模型,焊鉗要焊接高強(qiáng)度鋼板和低碳鋼板,并且焊鉗的槍臂要傳遞較大的機(jī)械力和電流。因此,焊鉗的強(qiáng)度,剛度和發(fā)熱要滿足一定的要求。并且要具有良好的導(dǎo)電性和導(dǎo)熱性。同時(shí),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(hào),以控制電阻焊機(jī)的動(dòng)作,以接通和斷開焊接電流,控制焊接電流的值,并進(jìn)行故障監(jiān)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(jiǎn)而言之,自動(dòng)焊接機(jī)轉(zhuǎn)盤式超聲波自動(dòng)焊接,與傳統(tǒng)的振動(dòng)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?yàn)椴皇褂弥竸?,大大降低了污染的風(fēng)險(xiǎn),從而提高了產(chǎn)品質(zhì)量;了因使用助焊劑,浪費(fèi)率低和可重復(fù)處理而造成的成本,自動(dòng)焊接機(jī)設(shè)備適用于批量生產(chǎn)和自動(dòng)化生產(chǎn)環(huán)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.
