自动焊接机器人在我们的生活中更为常见,并且使用更加频繁。但是,在使用过程中我们会遇到各种问题,因此您需要了解自动焊接机器系统的特性。自动焊机系统的结构特点:

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.机械
1. Machinery
自动焊接机的系统由三部分组成:机械装置,电源装置和控制装置。为满足焊接工艺要求,增压机构(焊钳)采用双冲程气动快速传递机构。可以通过改变行程控制手柄来改变焊钳的开度。它可以分为大孔径和小孔径,以满足焊接操作的要求。正常状态是焊钳打开一小段行程。当控制按钮切换到“开”位置时,通过按下手柄上的开关将夹具夹紧并加压。同时,在控制系统的控制下完成焊接循环后,电流将返回短行程。
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.电源装置
2. Power supply device
主电源电路由电阻焊接变压器,晶闸管单元,主电源开关,焊接电路等组成。目前,我们使用的焊接设备是单相工业频率交流电阻焊接机,功率为200kVA,二次输出电压为20V。由于生产了多个串联模型,焊钳要焊接高强度钢板和低碳钢板,并且焊钳的枪臂要传递较大的机械力和电流。因此,焊钳的强度,刚度和发热要满足一定的要求。并且要具有良好的导电性和导热性。同时,焊钳要用水冷却。因此,选择了可以承受400kg压力的新型焊钳。
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.控制装置
3. Control device
该控制装置主要提供信号,以控制电阻焊机的动作,以接通和断开焊接电流,控制焊接电流的值,并进行故障监视和处理。
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.
简而言之,自动焊接机转盘式超声波自动焊接,与传统的振动摩擦焊接和热熔焊接相比,超声焊接更具有快速,通常在二次清洗中完成焊接,因为不使用助焊剂,大大降低了污染的风险,从而提高了产品质量;消除了因使用助焊剂,浪费率低和可重复处理而造成的成本,自动焊接机设备适用于批量生产和自动化生产环境。
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.
