Description

Technical Field

[0001] The utility model relates to a quick disassembly and assembly mechanism, belonging to the technical field of robots. Background Art

[0002] With the continuous advancement of robot teaching technology, new teaching methods are emerging. The operator teaches once by holding the teaching handle, and the teaching system records the operator's teaching trajectory and reproduces the trajectory through the robot. Taking spraying as an example, the operator holds the teaching handle to demonstrate once, and the robot with the spray gun reproduces the teaching trajectory. This method of simulating human trajectory through the robot is a relatively simple teaching method with a low operating threshold.

[0003] Among them, in order to allow the operator to observe the actual spraying effect in real time during the teaching process, the best way is to use a real spray gun on the teaching handle and the spray gun can spray paint. For this reason, it is generally necessary to install a set of clamps on the teaching handle to clamp the spray gun. At the same time, the end of the robot must be installed with a spray gun that is as identical as possible through the clamp to achieve the best effect when reproducing.

[0004] However, when one set of spray guns is installed on the teaching handle and another set of spray guns is installed at the end of the robot, problems may arise: (1) It is difficult to make the two spray guns completely consistent: even if the same model and batch of spray guns are used, there are subtle differences in spray width, atomization, oil volume, fan shape and other effects. It is very difficult to adjust the two spray guns to be completely consistent in actual application scenarios, which makes it difficult to completely match the effect during teaching with the effect reproduced by the robot. (2) The hardware procurement cost increases: the spray gun on the teaching handle requires corresponding pumps, valves, electrostatic generators and other components, which is equivalent to increasing the system hardware procurement cost. (3) There is a waste of using two spray guns: the spray gun installed on the teaching handle is only used during teaching and is not used most of the time. In addition, since the paint generally has the problem of solidification, the spray gun and its pipes must be cleaned immediately after teaching. The general way to clean the spray gun is to use liquid consumables such as diluents to repeatedly flush the pipes and spray guns, which is a serious waste. (4) The gun cleaning process takes a long time, generally about ten minutes, which increases the workload of on-site operators and affects production efficiency. Utility Model Content
