点焊机器人的操作步骤

1.确保水和电完好无损，并释放安全门和光栅的警报。

2.当机器人处于手动状态时，将机器人光标移至警报栏，然后按All确认已启用焊接功能（示教盒屏幕左下角的蓝色按钮不在十字形内）。州）。

3.在机器人示教盒上选择输入/输出接口，检查是否重置了机器人的工作信号和工作完成信号，如果没有重置，请进行重置；然后将机器人示教盒上的状态选择开关转到自动位置。示教器上的程序指针将指向CELL主程序。 （如果示教盒上的程序指针未指向CELL主程序，则需要将机器人示教盒上的状态选择开关转到手动文件，然后在R1文件夹Cell程序中将其选中（按Enter选择）），然后将机器人示教盒上的状态选择开关切换到自动档}，机器人将切换到自动操作状态。

4.按下主控制台上的警报重置按钮，然后将手动/维护/自动选择开关设置为自动位置。

5.确认示教盒上的程序指针是否指向CELL主程序。

6.开启伺服电源：同时按下操作箱上的伺服电源按钮，开启定位器的伺服电源，相应的绿色伺服电源灯亮，并确保报警器红灯亮重置并关闭。如果没有，请按几次此重置按钮。然后按下启动按钮（2s），同时相应的指示灯亮起，工作站将进入自动运行状态。

简单的问题处理

1.如果机器人由于任何原因停止，请同时手动按下机器人和操作框，然后按一次或两次按操作框上的警报复位，然后将机器人光标移至报警栏，然后按全部确认重置警报，然后自动单击示教器，然后重复上述步骤6。

2.如果电极头掉落，则在其他机器人完成工作后，将示教盒和手术台切换为手动T1模式。如果安装方便，请按按钮并重新启动机器人。重置警报，将机器人光标移至警报栏，然后按全部进行确认，重置警报，然后将示教盒设置为自动，然后重复上述步骤6）；如果安装不方便，则需要将机器人移动到“位置”（不要撞到任何东西），更换后，将机器人移动到“停止”位置之前的位置（将机器人移动到靠近该位置的位置），然后选择该点到该点，并按住进行检查，直到机器人自动停止并确保在此过程中不会碰撞为止，只需重新启动即可。

发展趋势

编辑

点焊机器人的首次大规模使用将出现在发达地区。随着产业转移的进行，发达地区的制造业需要升级。基于增加工人成本的现实，点焊机器人的应用已成为最佳选择。未来，中国点焊机器人的大规模应用将集中在广东，江苏，上海，北京等地，其点焊机器人将占全国的一半以上。点焊机器人市场的增长及其巨大的市场潜力吸引了世界著名机器人制造商的关注。目前，从中国进口的点焊机器人主要来自日本，但是随着诸如“机器人”之类具有自有知识产权的公司的不断涌现，中国将越来越多地生产点焊机器人。

advantage

edit

The spot welding robot is composed of a robot body, a computer control system, a teaching box and a spot welding welding system. In order to adapt to the requirements of flexible movement, welding robots usually use the basic design of articulated industrial robots, which usually have six degrees of freedom: waist rotation, arm rotation, arm rotation, wrist rotation, wrist swing and wrist twist. There are two drive modes: hydraulic drive and electric drive. Among them, the electric drive has the advantages of easy maintenance, low energy consumption, fast speed, high precision, good safety and so on, so it has been widely used. The spot welding robot performs the spot welding operation according to the actions, sequences and parameters specified in the teaching process. The process is fully automated and has an interface to communicate with external devices. This interface can be used to accept superior master control and management computers. Control commands work.

Operation steps of spot welding robot



1. Make sure the water and electricity are intact and release the alarms of the safety gate and light grid.

2. When the robot is in the manual state, move the robot cursor to the alarm bar, and then press All to confirm that the welding function is enabled (the blue button in the lower left corner of the teaching box screen is not inside the cross). State).

3. Select the input / output interface on the robot teaching box, check whether the working signal and work completion signal of the robot are reset, if not reset, please reset; then turn the state selection switch on the robot teaching box To the automatic position. The program pointer on the teach pendant will point to the CELL main program. (If the program pointer on the teaching box does not point to the CELL main program, you need to turn the status selection switch on the robot teaching box to the manual file, and then select it in the Cell program in the R1 folder (press Enter to select)), Then switch the state selection switch on the robot teaching box to automatic mode}, and the robot will switch to the automatic operation state.

4. Press the alarm reset button on the main console, and then set the manual / maintenance / automatic selection switch to the automatic position.

5. Confirm whether the program pointer on the teaching box points to the CELL main program.

6. Turn on the servo power: simultaneously press the servo power button on the operation box to turn on the servo power of the positioner, the corresponding green servo power light is on, and make sure that the red light of the alarm is reset and turned off. If not, please press this reset button several times. Then press the start button (2s) and the corresponding indicator lights up, the workstation will enter the automatic operation state.

Simple problem handling

1. If the robot stops for any reason, please manually press the robot and the operation frame at the same time, then press the alarm reset on the operation frame once or twice, then move the robot cursor to the alarm bar, and then press all to confirm the reset alarm, Then click the Teach Pendant automatically and repeat step 6 above.

2. If the electrode head is dropped, after other robots complete the work, switch the teaching box and operating table to manual T1 mode. If the installation is convenient, press the button and restart the robot. Reset the alarm, move the robot cursor to the alarm bar, then press all to confirm, reset the alarm, then set the teaching box to automatic, and then repeat the above step 6); if the installation is not convenient, you need to move the robot to " "Position" (do not hit anything), after replacement, move the robot to the position before the "stop" position (move the robot to a position close to the position), then select the point to the point, and press and hold to check, Until the robot automatically stops and ensures that it will not collide during this process, just restart it.



development trend

edit

The first large-scale use of spot welding robots will appear in developed regions. As the industrial transfer proceeds, the manufacturing industry in developed regions needs to be upgraded. Based on the reality of increasing worker costs, the application of spot welding robots has become the best choice. In the future, large-scale application of spot welding robots in China will be concentrated in Guangdong, Jiangsu, Shanghai, Beijing and other places, and its spot welding robots will account for more than half of the country. The growth of the spot welding robot market and its huge market potential have attracted the attention of world-renowned robot manufacturers. At present, spot welding robots imported from China are mainly from Japan, but as companies such as "robots" with their own intellectual property continue to emerge, China will increasingly produce spot welding robots.
