It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0021] See also Figure 1-4The embodiment provided by the utility model is a mechanical arm picking mechanism for an injection molding barrel, comprising a moving component 1, a limit seat 2, an anti-skid component 3 and a blowing adsorption component 4. The moving component 1 comprises a circular frame 101. The inner part of the circular frame 101 is slidably connected to an electric control slide bar 102 for providing horizontal displacement. The outer surface of the electric control slide bar 102 is slidably connected to an electric control slider 103 for providing lateral displacement. The four corners of the circular frame 101 are fixedly connected to mounting ears 104. The surface of the ear 104 is provided with a threaded hole for convenient installation and fixing of the moving component 1. The anti-skid component 3 includes a mounting seat 301. A servo motor 302 is fixedly mounted on the side wall of the mounting seat 301 by bolts. A slide groove 303 is provided at the bottom end of the mounting seat 301. A bidirectional screw rod 306 is fixedly mounted on the output end of the servo motor 302 by a coupling. The outer surface of the bidirectional screw rod 306 is symmetrically threadedly connected with two screw slides 307. The outer surfaces of the screw slides 307 are both sleeved with clamps 304. The plates 304 are symmetrically distributed and penetrate the bottom end of the slide slot 303. The two clamping plates 304 are made of stainless steel and are L-shaped. The external dimensions of the top of the clamping plates 304 are compatible with the internal dimensions of the servo motor 302, which improves the stability of the movement of the clamping plates 304. The spray adsorption component 4 includes a connecting seat 2 401 fixed to the bottom end of the mounting seat 1 301 by bolts. The connecting seat 2 401 is in a Chinese-shaped shape. An air pump 402 is fixed at the inner bottom end of the connecting seat 2 401 to provide air power. The connecting seat 2 4 Two suction cup tubes 403 are symmetrically inserted at the bottom of 01 and are connected to the output end of the air pump 402 for blowing and adsorbing the injection molding barrel, which improves the adsorption stability of the suction cup tube 403. By starting the servo motor 302, the screw slide 307 can be driven to slide along the outer surface of the bidirectional screw 306 toward each other, thereby changing the distance between the two clamps 304, so that the two clamps 304 are clamped on the two side walls of the injection molding barrel. Under the action of friction, the stability of the injection molding barrel grasping is improved, and the injection molding barrel can be prevented from slipping.

[0022] The limit seat 2 includes a U-shaped frame 201 fixed at the bottom end of the electric control slider 103, and a cylinder 202 is fixed at the inner top end of the U-shaped frame 201. The output end of the bottom end of the cylinder 202 passes through the U-shaped frame 201 and is fixed at the top end of the mounting seat 301. By starting the cylinder 202, the anti-skid component 3 and the spray adsorption component 4 can be easily driven to move up and down.

[0023] The adjacent side walls of the two clamping plates 304 are both provided with anti-skid pads 305 , which are made of plastic material, thereby increasing the friction coefficient of the surface of the clamping plates 304 and further improving the stability of grasping.

[0024] Working principle: When the robot picking mechanism of this injection molding barrel is in use, the operator first connects the external power supply and fixes the mounting ear 104 to the top of the factory building by bolts. When the injection molding barrel is in motion, the electric control slide bar 102 can be started to move horizontally inside the circular frame 101, and the electric control slider 103 can be started to move along the direction of the electric control slide bar 102, thereby realizing the lateral movement of the electric control slider 103. The moving component 1 is the prior art and will not be described here. The mounting seat 301 can be pushed up and down by starting the cylinder 202, so as to facilitate the change of the height of the anti-slip component 3 and the blowing adsorption component 4. The air pump 402 is started to exhaust air through the suction cup tube 403 to remove dust from the surface of the injection molding part, and then the suction cup at the bottom of the suction cup tube 403 is aligned with the dust-free injection molding barrel to remove the part, and at the same time, the suction cup tube 403 is aligned with another injection molding barrel. The plastic barrel is subjected to a spray dust removal operation, and then the injection molded parts are grasped again and again to prevent the suction cup at the bottom of the suction cup tube 403 from being contaminated with too much dust or impurities on the surface of the injection molded parts that need to be adsorbed, which affects its grasping operation and reduces the error rate of injection molded parts removal. The spray adsorption component 4 is a prior art and will not be described here. By starting the servo motor 302, the screw slide 307 can be driven to slide toward each other along the outer surface of the bidirectional screw 306, thereby changing the spacing between the two clamps 304, so that the two clamps 304 are clamped on the two side walls of the injection barrel. Under the action of friction, the stability of grasping the injection barrel can be improved to prevent the injection barrel from slipping and causing economic losses. The anti-skid pad 305 is made of rubber material and is sleeved on the side wall of the clamp 304. The rough surface of the anti-skid pad 305 further increases the friction resistance between the clamp 304 and the injection barrel.
