Industrial robot tool quick change installation

- Sep 18, 2019-

Robot tool quick-change installation allows a single robot to communicate with different end-effectors during manufacturing and assembly to increase flexibility. It is commonly used in automatic spot welding, arc welding, data snatching, stamping, inspection, crimping, assembly, and data. Removal, burr clearing, packaging, etc., with production line change


Quickly and effectively reduce downtime and many other advantages.


At present, foreign countries are more advanced in robot automatic change technology, starting early, high level of specialization, but expensive, technology is not external, the products produced have their own characteristics, more famous brands such as the United States DE-STA-CO, ATI , AGI, RAD, etc., and other local robot companies such as STAUBLI also have


Quick change installation for different models. OPT's tool quick-change installation is widely used in various automation industries such as automobile manufacturing, medical, aviation, food, etc. due to its common gas pressure loss maintenance function, high reliability, high repeatability and other characteristics.


Robotic tool changer installation (RoboticToolChanger) makes the robot application more flexible by allowing the robot to automatically change different end effectors or peripherals. These end effectors and peripherals include, for example, spot welding torches, grippers, vacuum tools, pneumatic and electric motors, and the like. Tool change


The installation includes a robot side for mounting on the robot arm and a tool side for mounting on the end effector. The tool quick change installation allows different media such as gases, electrical signals, liquids, video, ultrasound, etc. to be connected from the robot arm to the end effector. Robot tool quick change installation


The advantages are:


1. Production line change can be completed in a few seconds;


2. Maintenance and repair tools can be quickly changed, greatly reducing downtime;


3. Increase the flexibility by using more than one end effector in the application;


4. Use the end effector of the automatic communication single function to replace the original stupid and anti-complex multi-purpose tooling actuator.


The tool quick change installation is divided into the robot side (Masterside) and the tool side (Toolside), the robot side device is on the robot front end arm, the tool side device is on the execution tool (the tool is the welding tongs, the gripper, etc.), and the tool quick change installation can Quickly complete electricity, gas and liquid between the robot side and the execution tool


The body is connected. A robot side can be used in conjunction with multiple tool sides according to the user's practical conditions, increasing the flexible manufacturing of the robot production line, increasing the efficiency of the robot production line and reducing the production cost. The underlying principle is as follows:


The general construction of the tool quick change joint is shown below:


Consider the following information when choosing a tool quick change installation:


1. The torque resistance of the tool quick change installation - due to the tool quick change installation side of the robot side locking tool, along with the robot moving with a certain acceleration, plus the eccentricity of the execution tool, its own gravity, will constitute a large torque; The torque can be poor, and the opening angle will be formed between the robot side and the tool side.


The bus signal is suffixed, leaking/gas, and serious tools will fall.


2, tool quick change installation with gas pressure loss maintenance function - tool quick change installation most use pneumatic locking mechanism (ATI has electric drive open tool quick change installation), if debugging, application when the gas source infix, tool change The side of the mounting robot must adhere to the side of the locking tool. ATI relies on its own mechanical design.


The gas pressure loss maintenance function can be completed without the need of a spring; the spring itself has a clip and aging, and it is very unreliable to complete the gas pressure loss maintenance function;


3, tool quick change installation with tool bracket interlock function - robot demand control solenoid valve to tool quick change installation gas supply, complete tool quick change installation lock / open; in debugging, it is easy to give due to misuse Error instruction; ATI tool quick change installation through various monitorable links and tools


With the frame, when the normal operation is completed, even if the operation is given by the wrong operation, the tool quick-change installation will not perform the opening operation; if the DeviceNet bus control is used, the controller can detect these signals;


4, tool quick change installation has the possibility of online maintenance / repair - the production of the car factory is not allowed to exhibit a long-term shutdown, ATI tool quick-change installation with modular design, an all-in-one hex wrench can complete everything in 10 minutes Replacement of consumables; ATI provides a partial 3-year warranty policy for tool quick-change installation machinery.


Due to the problems caused by quality, processing defects, etc., we are repairing or changing new products;


5, tool quick change installation must provide professional technical training - let the car factory on-site maintenance personnel, and we understand the tool quick change installation, skillful completion of maintenance and repair;


6, think about the long-term use of the tool quick-change installation cost-tool quick-change installation as production equipment, customers must first pass the product's adherence, spare parts purchase and equipment provider's value-added service to consider its long-term use of the cost.
