Briefly describe the manual operation steps of linear motion of industrial robot.
Manual operation steps of straight-line motion of industrial robot:
The main contents are as follows: 1. Select the manual mode of the robot operation station and the instructor mode.
2. Observe the surrounding environment of the robot to avoid obstacles and affect the movement of the robot.
3. Use the instructor to power on, observe whether the robot and servo controller or motor react, and then adjust the moving speed to low speed [the speed is too fast and collide or reach the moving limit].
4. I can write a linear motion program by using the LINE instruction at two points of the new program equipment AB through the instructor, or find the previous program to call the straight line instruction from it.
5. Move the robot to the Home position after the operation is completed.
Industrial robot applications:
1. Application in palletizing:
In the palletizing of all kinds of factories, highly automated robots are widely used, manual palletizing work is intensive and labor-consuming, employees not only need to bear great pressure, but also have low work efficiency.
According to the characteristics of the moving object and the place where the moving object is classified, the handling robot can carry out efficient classification and transportation on the basis of keeping its shape and the properties of the object unchanged, so that the packing equipment can complete hundreds of palletizing tasks per hour. It plays an important role in loading and unloading of production line, handling of containers and so on.
2. Application in welding:
Welding robot is mainly responsible for welding work, and different industrial types have different industrial requirements, so the common welding robots are spot welding robot, arc welding robot, laser robot and so on. Automobile manufacturing industry is the most widely used industry of welding robot, which has incomparable advantages over manual welding in welding difficulty, welding quantity, welding quality and so on.
3. Application in assembly:
In industrial production, the assembly of parts is a huge amount of work, which requires a lot of labor. The former human assembly has been gradually replaced by industrial robots because of its high error rate and low efficiency. The research and development of assembly robot combines a variety of technologies, including communication technology, automatic control, optical principle, microelectronics and so on.
According to the assembly process, R & D personnel write appropriate programs and apply them to specific assembly work. The most important feature of assembly robot is high installation precision, great flexibility and high durability. Because the assembly work is complex and meticulous, we choose the assembly robot to install electronic parts and automobile fine parts.
4. Application in detection:
The robot has multi-dimensional additional functions. It can replace the work of staff in special positions, such as detection in high-risk areas such as nuclear contaminated areas, toxic areas, nuclear contaminated areas, high-risk unknown areas. There are also places that human beings can not specifically reach, such as the detection of sick parts of patients, the detection of industrial defects, the detection of life at the scene of earthquake relief, and so on.
A brief description of the operation steps of industrial robots
Industrial robot operation can not be explained clearly in thousands of words, the basic steps are that you may not be on the job after several months of vocational training, this is not playing with your mobile phone. For example, the operation of welding industrial robots in our company generally adopts the teaching method, that is, the operation keys of the teaching box are guided to the starting point, and then the keys are used to determine the position and mode of movement.

, swing mode, welding torch posture by professional engineers and various welding parameters. At the same time, the movement speed of the peripheral equipment can be determined through the teaching box. The welding process operation includes starting arc, welding arc extinguishing, filling burner, etc., which is also given through the teaching box. After the teaching is finished, the robot control system enters the program editing state, and the actual instruction operation can be carried out after the data program is generated.
How to integrate with CNC machine tools, hardware selection, integration steps, matters needing attention
1. Hardware selection
(1) composition of loading and unloading workstation for industrial robot
A typical industrial robot CNC machine tool loading and unloading workstation system is shown in figure 1. The main components include industrial robots, CNC machine tools, workpieces, grasping claws, peripheral equipment and system controllers.
The communication mode between industrial robot and CNC machine tool is also different according to different systems. For the system with less signal, the Icano signal line can be directly used to connect, at least including gating signal, clamping signal and machining completion signal. For systems with more signals, fieldbus and industrial Ethernet can be used to communicate.
(2) selection of loading and unloading robot
The CNC machine tool introduced in this example is a cylinder with a weight of ≤ 2kg, so the machine tool loading and unloading robot can choose Yaskawa MH6 robot, as shown in figure 3. The robot control system is Yaskawa DXl00.
The shape and quality of the clamping object should be taken into account in selecting the end effector of the industrial robot. in this example, the pneumatic claw is selected, as shown in figure 4, the type is HDS-20Y, and the solenoid valve which controls the claw movement is installed on the MH6 robot body. If the quality of the workpiece is large, you can choose hydraulic claws.
Considering the safety of power loss, the clamped workpiece should not fall after power loss, so the solenoid valve adopts double electric control. The pneumatic control circuit of the end effector is shown in figure 5. When the YV1 solenoid valve coil is powered on, the pneumatic claw shrinks and clamps the workpiece; when the YV2 solenoid valve coil is powered on, the pneumatic claw is released to release the workpiece; when the YV1 and YV2 solenoid valve coils are not energized, the pneumatic claw remains in its original state. The solenoid valve cannot be powered on at the same time.
(3) selection of PLC control cabinet and safety protection device
The PLC control cabinet is used to install components such as circuit breakers, PLC, switching power supplies, intermediate relays and transformers. PLC chooses the NJ301-1100 controller of OMRON company, which controls the start and stop of the loading and unloading robot and the operation of the conveying line.
The commonly used security protection is shown in figure 6, which has a security fence and a safety grating. Safety fence is selected for this workstation.
Install the loading and unloading robot and confirm what the contents of the box are.
Loading and unloading robot is a kind of automatic equipment, which can be used for material transportation and handling on industrial production line. Its installation needs to consider the following steps:
1. Determine the position of the robot: determine the installation position of the robot according to the requirements of the production line to ensure that the robot can load and unload materials smoothly.
two。 Installation robot: assemble and install the robot according to the instructions of the robot, and debug and test the electrical and software.
3. Connect and configure the system: connect robots and other devices for network configuration and parameter setting of the system.
4. Writing program: write the operation program of the robot, set its working mode and running logic according to the requirements of the production line.
When confirming the contents of the box, you can use the following ways:
1. Scan or identify the goods through bar code or RFID technology to confirm whether the packing content is correct.
two。 The visual recognition technology is used to identify the image of the boxed goods in order to judge whether they meet the requirements.
3. Cooperate with personnel for human-computer interaction, data entry and inspection to ensure the quantity and quality of boxed goods.
4. Place labels or marks in each box to record the name, quantity and bar code of the items contained in the box, so as to facilitate follow-up management and tracking.
