Description

Technical Field

[0001] The utility model relates to a detection structure, in particular to a robot quick-change disc locking detection mechanism, belonging to the technical field of robot quick-change discs. Background Art

[0002] The robot quick-change plate is also called the robot quick-change device, gun change plate, quick changer, quick-change tool plate, etc. It is a flexible connection tool used on the end effector in the industrial robot industry. Its main function is to achieve the rapid replacement of the robot end effector to increase the flexibility of the industrial robot, improve production efficiency, and reduce production costs. The robot quick-change plate usually consists of two parts: the robot side and the tool side. The robot side is installed at the end of the robot, while the tool side is installed together with the execution tool (such as welding gun, manipulator, fixture, etc.). The two parts are connected quickly and firmly through a mechanical locking mechanism, while ensuring high-precision positioning.

[0003] During the use of the robot quick-change disk, the main disk on the robot side and the sub-disk on the tool side are connected by a mechanical locking mechanism. However, most of the existing robot quick-change disks are not equipped with a locking detection mechanism. Therefore, after the quick-change disk is locked, the staff cannot obtain the signal feedback after locking. When the quick-change disk has insufficient air pressure or accessory failure, the staff cannot discover the problem in time, resulting in reduced safety during the use of the quick-change disk. Therefore, a robot quick-change disk locking detection mechanism is proposed. Utility Model Content

[0030] A proximity sensor 14 is installed on the inner wall of the main disk body 11, a through slot 15 is opened on one side of the main disk body 11, a magnetic sensor 16 is installed inside the through slot 15, a piston 112 is slidably connected to the inner wall of the main disk body 11, and a magnetic ring 116 is fixedly connected to the outer wall of the piston 112;

[0031] A sub-disk assembly 20 is disposed on one side of the main disk assembly 10 .

[0032] In this embodiment, specifically: the main disk assembly 10 further includes a guide sleeve 12 and a locking steel ball 13;

[0033] A guide sleeve 12 is fixedly connected to one side of the main disk body 11, and a locking steel ball 13 is evenly slidably connected to the inner wall of the guide sleeve 12. The piston 112 is slidably connected to the inner wall of the guide sleeve 12. Air is introduced into the main disk body 11 through the air intake pipeline to push the piston 112 to move. During the movement of the piston 112, the locking steel ball 13 on the side wall of the guide sleeve 12 is pushed to move, so that the locking steel ball 13 is close to the side wall of the slide groove 22.

[0034] In this embodiment, specifically: ventilation holes 17 are evenly opened on one side of the main plate body 11 , and air-stopping steel balls 110 are slidably connected to the inner side walls of the ventilation holes 17 .

[0035] In this embodiment, specifically: the outer wall of the air-stopping steel ball 110 is fixedly connected with a spring 19, one end of the spring 19 is fixedly connected with a sealing bolt 18, the sealing bolt 18 is used to fix the air-stopping steel ball 110, and the air-stopping steel ball 110 slides inside the vent hole 17 to ensure unidirectional flow of gas and prevent gas backflow from causing insufficient air pressure.

[0036] In this embodiment, specifically: grooves 113 are evenly formed on the outer wall of the piston 112 , and a guide ring 114 is fixedly connected to the outer wall of the piston 112 , and the guide ring 114 plays a guiding role during the movement of the piston 112 .

[0037] In this embodiment, specifically: a sealing ring 115 is fixedly connected to the outer wall of the piston 112 to prevent air leakage during the movement of the piston 112.

[0038] In this embodiment, specifically: the auxiliary tray assembly 20 includes an auxiliary tray body 21 and a slide groove 22;

After the main disk body 11 and the auxiliary disk body 21 are locked, the distance between the main disk body 11 and the auxiliary disk body 21 is detected by the proximity sensor 14 to ensure that the main disk body 11 and the auxiliary disk body 21 are tightly connected, confirming that the locking mechanism works normally, improving the safety of the robot quick-change disk during use, and detecting the position of the magnetic ring 116 on the piston 112 by the magnetic sensor 16 to confirm whether the piston 112 is in place to prevent the internal piston 112 from failing. When the piston 112 fails, a signal feedback problem is sent to the console through the communication interface 31 to remind personnel to repair the quick-change disk in time.
