DETAILED DESCRIPTION

[0022] In order to make the purpose and advantages of the utility model more clear, the utility model is specifically described in combination with the following embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the utility model, and does not strictly limit the protection scope of the specific request of the utility model.

[0023] like Figure 3-6 As shown, an adsorption conveying robot arm includes a sliding arm 1 and a chassis 2, the chassis 2 is electrically rotatably connected to one end of the sliding arm 1, a disk cover 201 is fixedly connected to the top of the chassis 2, a hollow groove 203 is penetrated in the middle of the chassis 2 and the disk cover 201, a fixed block 204 is symmetrically fixedly connected to the inner wall of the hollow groove 203, a rotating disk 206 is rotatably provided in the middle of the hollow groove 203, the rotating disk 206 is rotatably connected to the fixed block 204, and the rotating disk 206 is The outer walls on both sides are fixedly connected with a rotating rod 216, and the outer wall of the hollow groove 203 is penetrated with a rotating groove 214 for the rotating rod 216 to rotate. The bottom of the rotating disk 206 is fixedly connected with a screw rod 205, and the outer wall of the screw rod 205 is slidably connected with a sliding ring 215. The sliding ring 215 is slidably engaged with the rotating disk 206 and the fixed block 204 at the same time through an insertion rod 217. The outer wall of the screw rod 205 and the bottom of the sliding ring 215 are threadedly connected with a nut 207.

[0024] According to the above structure, the nut 207 is rotated to separate it from the screw rod 205, and the sliding ring 215 is slid to make the insertion rod 217 separate from the rotating disk 206 and the fixed block 204 at the same time. The rotating screw rod 205 is rotated to drive the rotating disk 206 to rotate, and the rotating disk 206 drives the rotating rod 216 to rotate inside the disk cover 201. The above steps are performed in reverse order to fix the rotating disk 206 so that it no longer rotates.

[0025] See attached Figure 1 , Figure 2 , Figure 4 , Figure 6A trachea groove 202 is spirally provided at the bottom of the chassis 2, and a clip 208 is slidably inserted inside the trachea groove 202. A groove 211 for the clip 208 to slide through is provided on the top of the chassis 2. A suction cup 210 is spirally distributed inside the trachea groove 202. The suction cup 210 is fixedly connected to the clip 208 through a connecting column 213. Several connecting columns 213 are fixedly connected through the trachea 209, and a suction pipe 212 is fixedly connected to the top of one of the connecting columns 213. The sliding arm 1 is fixedly connected to the suction pipe 212. A notch 218 for the rotation of the rotating rod 216 is provided on the top of the clip 208, and a locking groove 219 for the rotation and engagement of the rotating rod 216 is provided on the top of the clip 208.

[0026] According to the above structure, the rotation of the rotating disk 206 will form the engagement or separation of the rotating rod 216 and the locking groove 219, so that the clip 208 slides out from the inside of the disk cover 201 through the embedding groove 211, and the clip 208 together with the connecting column 213, the air pipe 209, and the suction cup 210 can be removed from the inside of the air pipe groove 202, which is convenient for maintenance and replacement. The suction pipe 212 allows the air pipe 209 to absorb air through the suction cup 210, and the spiral arrangement of the air pipe groove 202 and the suction cup 210 at the bottom of the chassis 2 can expand the adsorption area and reduce the adsorption dead angle. The opening facilitates the rotation of the rotating rod 216 and has a certain blocking and limiting effect on the rotating rod 216. The utility model can integrate the air pipe 209 and the suction cup 210 inside the chassis 2. The structure is neat and flat, the adsorption area is wider, the adsorption dead angle is reduced, and the air pipe 209 and the suction cup 210 are exposed and scattered outside during the adsorption and transportation of the mold. The situation of being connected with other equipment parts is avoided, thereby avoiding the rupture of the air pipe 209. The suction cup 210 and the air pipe 209 can be disassembled relatively conveniently, which is convenient for subsequent replacement and maintenance.

[0027] The working principle of the utility model is as follows: by rotating the nut 207 to separate it from the screw 205, sliding the sliding ring 215 to make the insertion rod 217 separate from the rotating disk 206 and the fixed block 204 at the same time, rotating the screw 205 to drive the rotating disk 206 to rotate, and the rotating disk 206 drives the rotating rod 216 to rotate inside the disk cover 201. Reversely operate the above steps, then the rotating disk 206 can be fixed and no longer rotated; the rotation of the rotating disk 206 will form the engagement or separation of the rotating rod 216 and the locking groove 219, so that the clip 208 is By sliding out from the inside of the disc cover 201 through the embedded groove 211, the clip 208 together with the connecting column 213, the air pipe 209, and the suction cup 210 can be removed from the inside of the air pipe groove 202 for easy inspection and replacement. The suction pipe 212 allows the air pipe 209 to inhale air through the suction cup 210, and the spiral arrangement of the air pipe groove 202 and the suction cup 210 at the bottom of the chassis 2 can expand the adsorption area and reduce the adsorption dead angle. The opening of the missing groove 218 facilitates the rotation of the rotating rod 216 and has a certain blocking and limiting effect on the rotating rod 216.

[0028] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention.
