Description

Technical Field

[0001] The utility model relates to the field of fastening components, and particularly to a rotary fastening mechanism. Background Technique

[0002] When fastening between an upper cover and a lower cover, generally a flat suction and flat fastening method is adopted. The upper cover is adsorbed by a manipulator. When the covers are fastened, the manipulator moves vertically downward again, so that the upper cover can be fastened to the lower cover. However, this fastening method is applicable to the case where the gap between the upper and lower products is large. When the gap between the upper and lower products is small and there are adverse factors such as incoming material deformation, the vertical movement accuracy of the manipulator is relatively low, the deformation amount of the injection molded part shell is relatively large, the fastening is unstable, and it is difficult to accurately align and fasten the upper cover and the lower cover, resulting in a low success rate of fastening between the upper cover and the lower cover.

By means of the lifting frame 311, it is convenient to connect with the output end of the lifting cylinder 2, and by means of the support frame 313, it is convenient to provide support for the fixed-axis rotation of the rotary assembly 321.

[0045] Specifically, the rotary fastening mechanism 32 includes: a rotary assembly 321, which is rotatably arranged at the bottom of the mounting mechanism 31; a pneumatic extrusion assembly 322, which is installed between the rotary assembly 321 and the mounting mechanism 31, and the pneumatic extrusion assembly 322 is used to provide power for the rotation of the rotary assembly 321; an adsorption assembly 323, which is installed on the rotary assembly 321, and the adsorption assembly 323 is respectively arranged on both sides of the pneumatic extrusion assembly 322. The upper cover is adsorbed by the adsorption assembly 323. At this time, the upper cover is in an inclined state. The lifting cylinder 2 drives the upper cover to move downward, so that the upper cover is buckled from one side of the lower cover first to realize the pre-fastening between the upper cover and the lower cover. Then, an external air pump is used to blow gas into the pneumatic extrusion assembly 322 to push the rotary assembly 321 to rotate axially relative to the mounting mechanism 31, so as to facilitate the rotary pressing of the inclined upper cover, and thus the upper cover and the lower cover can be completely fastened. By the axial rotation of the rotary assembly 321 relative to the support frame 313, it is convenient to rotate and press the inclined upper cover, and the adsorption of the upper cover is facilitated by the adsorption assembly 323.

[0046] Specifically, the rotary assembly 321 includes: a rotary frame 3211, which is arranged between the support frames 313; a rotating shaft 3212, which is respectively connected to both sides of the rotary frame 3211, and the rotating shaft 3212 is rotatably inserted and connected to the bottom of the support frame 313.
