The second limiting frame 33 is fixedly installed on the outer surface of one end of the rotating shaft 36. One end of the rotating shaft 36 is rotatably clamped on the outer surface of the bottom end of the micro motor 31. The bottom surface of the second limiting frame 33 is slidably plugged with a second arc-shaped clamping block 34. One end of the second limiting frame 33 is provided with an air port 35. The outer surfaces of the rotating shaft 36 and one end of the micro motor 31 are both fixedly installed with a second bevel gear ring 32.

[0029] The bottom end of the first micro cylinder 13 is aligned with the bottom center of the rubber tube 11 , and the bottom end of the air pipe 21 is internally connected to one end of the first limiting frame 25 . Both ends of the first limiting frame 25 are rotatably mounted on the outer surfaces of both ends of the rotating shaft 36 through the sleeve holes 23 .

[0030] Through the above technical scheme, the bottom end of the first micro-cylinder 13 can be aligned with the bottom center of the rubber cylinder 11, so as to drive the rubber head 14 to rise and fall inside the rubber cylinder 11. The bottom end of the air pipe 21 is internally connected with one end of the first limit frame 25. By extracting the air inside the first limit frame 25, the first arc-shaped block 26 rises to clamp the rubber head 14. The two ends of the first limit frame 25 are rotatably installed on the outer surfaces of the two ends of the rotating shaft 36 through the socket hole 23, ensuring that the first limit frame 25 and the second limit frame 33 are kept flipped synchronously.

The outer surfaces of both ends of the first fastening arc hoop 22 are connected with fastening screws, and the first fastening arc hoop 22 is fastened to the second fastening arc hoop 37 by fastening bolts, so that the first limiting component 2 and the second limiting component 3 are fixedly installed on the outer surface of one end of the robot arm 4, ensuring the stability of the operation of the first limiting component 2 and the second limiting component 3.

[0035] The working principle of the utility model is as follows: during the gluing process of the mechanical arm, when the glue head 14 needs to be replaced, the two groups of first micro-cylinders 13 are first controlled to run synchronously and extend downward, so that the glue head 14 descends due to gravity inside the glue barrel 11 until the glue head 14 descends to the bottom of the glue barrel 11, and then the air pump is controlled to add air to the inside of the air pipe 21, thereby pushing the first arc-shaped block 26 and the second arc-shaped block 34 to descend at the ends of the first limit frame 25 and the second limit frame 33, and then the micro-motor 31 is controlled to rotate and run, so that the micro-motor 31 drives the rotating shaft 36 and the first bevel gear ring 24 to rotate synchronously in the opposite direction through the second bevel gear ring 32 at the bottom, and at the same time, the first limit frame 25 and the second limit frame 33 are flipped away from each other, and after the second arc-shaped block 34 and the first arc-shaped block 26 are separated from the previous glue head 14, the second micro-cylinder 16 is controlled to drive the limit frame 15 at one end to retract and slide, so that the limit frame 15 drives the new and old groups of glue heads 14 to slide synchronously, so that the old glue head 14 slides to the other group of glue barrels 11 At the bottom center, the new glue head 14 moves to the middle part of the limiting slide 12 to wait for installation, and then the micro motor 31 rotates in the opposite direction, driving the second limiting frame 33 and the first limiting frame 25 to flip close to each other until the first arc-shaped block 26 and the second arc-shaped block 34 are close to both sides of the glue head 14, and then the air pump is controlled to extract the air inside the air pipe 21, so that the first arc-shaped block 26 and the second arc-shaped block 34 rise to clamp the new glue head 14 and align it with the rubber hose at one end of the robot arm 4, and then control another group of first micro cylinders 13 to retract and drive the replaced glue head 14 to rise and enter the interior of the rubber tube 11, thereby completing the automatic replacement of the glue head 14, and then continue to control the robot arm 4 to clamp the glue head 14 through the first limiting component 2 and the second limiting component 3 at one end to perform the gluing work, through the coordinated operation between the storage component 1, the first limiting component 2 and the second limiting component 3, the glue head 14 can be automatically replaced at one end of the robot arm 4, thereby improving the replacement efficiency of the glue head 14.

[0036] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
