Description

Technical Field

[0001] The utility model relates to the technical field of manipulators, in particular to a novel manipulator for an injection molding machine. Background Art

[0002] In the process of unloading the injection molding machine, a robot is used to unload the finished product from the injection molding machine. First, the robot can improve production efficiency. Compared with manual operation, the robot can work continuously without being affected by factors such as fatigue and emotions, which greatly speeds up production. Secondly, the robot can ensure the stability and consistency of the production process.

[0003] The end of the robot used in conjunction with the injection molding machine generally uses a suction cup structure to remove the injection molded product from the injection molding machine, and the installation position of the suction cup at the end of the robot can be adjusted according to actual operations. However, the existing suction cup structure at the end of the robot cannot provide an effective angle condition for some injection molded products with multiple special-shaped surfaces. Since the suction cup cannot be adjusted at an angle, it may not be able to fully fit the special-shaped surface, resulting in loose adsorption or inability to grasp. If the special-shaped surface of the injection molded product has a complex shape or a special angle, the suction cup may not be able to adapt to these changes, resulting in loose adsorption or inability to effectively grasp.

The upper end of the locking seat 11 is connected to the main pipe in the machine head 7 through a pipeline. An angle condition mechanism 12 is arranged between the suction cup 9 and the connecting seat 10. The angle condition mechanism 12 includes two arc-shaped sleeve rods 13, a mounting seat 15 and a connecting rod 16. The two arc-shaped sleeve rods 13 are fixedly installed on the suction cup 9, and the mounting seat 15 is movably installed on the outside of the connecting seat 10. One end of the connecting rod 16 is movably installed between the two arc-shaped sleeve rods 13, and the other end of the connecting rod 16 is movably installed in the mounting seat 15 through the rotating shaft 24.

[0023] like Figure 3-Figure 5As shown, a fixing tube 17 is fixedly installed on the upper end of the suction cup 9, and a rotating ball 18 is fixedly installed on the upper end of the fixing tube 17. The rotating ball 18 is rotatably installed at the lower end of the connecting seat 10. The suction cup 9 is rotatably installed on the lower end of the connecting seat 10 through the rotating ball 18, so that the adsorption angle of the suction cup 9 can be adjusted. A fixing ring 14 is fixedly installed on the outer side of the connecting seat 10, and a slide groove 19 is provided on the outer side of the fixing ring 14. The longitudinal section of the slide groove 19 is T-shaped, and the upper end of the connecting seat 10 is threadedly connected to the lower end of the locking seat 11. The setting of the fixing ring 14 and the opening of the slide groove 19 on the outer side of the fixing ring 14 can provide conditions for the installation of the mounting seat 15. The two arc sleeve rods 13 are respectively inserted and installed on the outer side of the fixing tube 17, and the two ends of the two arc sleeve rods 13 are fixedly connected by connecting bolts 20.

[0024] like Figure 4-Figure 6 As shown, the mounting seat 15 is in a C-shaped structure, and a slider 22 is fixedly installed at one end of the mounting seat 15, and the slider 22 is slidably installed in the slide groove 19. Limit screws 23 are inserted and installed on both sides of the mounting seat 15, and screw grooves 25 are opened at the center positions of both sides of the rotating shaft 24. The rotating shaft 24 is placed in the mounting seat 15, and one end of the two limit screws 23 is respectively threadedly connected in the corresponding screw grooves 25, and a sleeve 21 is fixedly installed at one end of the connecting rod 16, and the sleeve 21 is inserted and installed on the outside of the corresponding connecting bolt 20, and the other end of the connecting rod 16 extends through the through hole in the rotating shaft 24 to the position above the rotating shaft 24 and is threadedly connected with a nut, and the arc sleeve 13 and the mounting seat 15 are movably connected through the connecting rod 16 and the rotating shaft 24, so that the suction cup 9 can be quickly fixed at an angle after the angle is adjusted at the lower end of the connecting seat 10 through the rotating ball 18.

[0025] It should be noted that the utility model is a novel manipulator for injection molding machines. When it is necessary to adjust the suction cup 9 by an adsorption angle, the nut at one end of the connecting rod 16 can be unscrewed first, and then the suction cup 9 can be rotated at the lower end of the connecting seat 10 with the rotating ball 18 as the axis. At the same time, since the suction cup 9 rotates with the rotating ball 18 as the axis, the fixing tube 17 synchronously drives the connecting rod 16 to rotate through the connecting bolt 20 between the two arc-shaped sleeve rods 13. Therefore, one end of the connecting rod 16 is inserted and installed in the rotating shaft 24, so that the connecting rod 16 can drive the mounting seat 15 to rotate through the screw groove 25, and then the slider 22 at one end of the mounting seat 15 rotates in the slide groove 19, so that the positions of the arc-shaped sleeve rod 13, the fixing ring 14 and the connecting rod 16 can be synchronously adjusted with the rotation of the suction cup 9, and the arc-shaped sleeve rod 13 and the connecting rod 16, The mounting seat 15 is rotated to the direction in which the angle of the suction cup 9 needs to be adjusted, and then the suction cup 9 is rotated to one side with the rotating ball 18 as the axis to adjust the angle. As a result, the suction cup 9 pushes the connecting rod 16 to move obliquely upward through the fixing tube 17, the arc sleeve rod 13, and the connecting bolt 20. As a result, the other end of the connecting rod 16 is inserted and moved in the through hole of the rotating shaft 24 and as the angle of the arc sleeve rod 13 and the mounting seat 15 changes, one end of the connecting rod 16 rotates outside the connecting bolt 20 through the sleeve 21, and the other end of the connecting rod 16 is inserted and moved in the through hole in the rotating shaft 24 and makes the rotating shaft 24 rotate in the mounting seat 15 with the two limit screws 23 as the axis. When the angle adjustment of the suction cup 9 is completed, the nut can be threadedly connected to the connecting rod 16 located above the rotating shaft 24, thereby limiting and fixing the suction cup 9 after the angle adjustment.
