DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] The utility model provides a technical solution:

[0028] See also Figures 1 to 4 A CNC machining automatic material picking component includes a manipulator 1, a stepper motor 2 is fixed to the end of the manipulator 1 by bolts, a fixed rod 3 is fixed to the power output shaft of the stepper motor 2, an adjustment mechanism for adjusting the material picking is connected to the end of the fixed rod 3, and both ends of the adjustment mechanism are connected to an adsorption mechanism for picking up the workpiece;

[0029] The adjusting mechanism comprises an adjusting member 4, which is fixed to the end of the fixing rod 3, and both ends of the adjusting member 4 are connected to movable plates 43;

[0030] The adsorption mechanism includes a connecting tube 5, which is fixed at the ends of the two movable plates 43 respectively, one end of the connecting tube 5 is connected with a connecting port 51, the other end of the connecting tube 5 is telescopically connected with a movable tube 52, the end of the movable tube 52 is connected with a suction cup 53, one side of the suction cup 53 is abutted and connected with a spring 54 sleeved on the outer surface of the movable tube 52, a fixed ring 55 is fixed to the inner wall of the connecting tube 5, a movable ring 56 is fixed to the end of the movable tube 52, one side of the movable ring 56 is provided with a through hole 57 interconnected with the movable tube 52, and the diameter of the movable ring 56 is smaller than the fixed ring 55.

[0031] By adopting the above technical scheme, before using the CNC machining automatic material picking component, the manipulator 1 is first placed in a suitable position. After the manipulator 1 drives the two suction cups 53 to contact the outer surface of the workpiece, the adjusting member 4 is pushed toward the workpiece again, so that the suction cup 53 can push the movable tube 52 to move. At the same time, the suction cup 53 pushes the spring 54 to move and compress. When the movable tube 52 moves, it drives the movable ring 56 and the fixed ring 55 to separate. At this time, the air in the connecting tube 5 is extracted. Since the movable ring 56 and the fixed ring 55 are separated, the negative pressure air can reach the suction cup 53 through the through hole 57, and the air in the suction cup 53 is extracted to achieve the effect of adsorbing the workpiece. When the manipulator 1 moves the workpiece, the spring 54 loses the external pressure. Under the effect of the elastic reset of the spring 54 itself, it will push the suction cup 53 to move, so that the movable ring 56 moves to fit the fixed ring 55, and the through hole 57 is sealed, thereby reducing the leakage of the suction cup 53 and improving practicality.

[0032] Specifically, Figure 1-Figure 4 As shown, a dual-axis motor 41 is fixed to the inside of the adjusting member 4 by bolts, a screw 42 is fixed to the power output shaft of the dual-axis motor 41, and the screw 42 is threadedly connected to the movable plate 43. A limiting block 44 is fixed to the inside of one side of the movable plate 43 and close to the adjusting member 4, and the end of the connecting port 51 is connected to the air pipe 6. A limiting plate 7 for limiting the air pipe 6 is fixed to the outer surface of the manipulator 1. A negative pressure box 8 connected to the air pipe 6 is installed on one side of the manipulator 1, and a vacuum pump 9 is connected to the right side of the negative pressure box 8. The output end of the vacuum pump 9 is connected to an exhaust pipe 12. A fixed base 10 is fixed to the lower end of the manipulator 1, and a fixing bolt 11 is fixed to the inside of the fixed base 10.

[0033] By adopting the above technical scheme, the stability of the manipulator 1 can be ensured by fixing the base 10, and then the fixing bolts 11 are tightened to fix the fixed base 10. When in use, the set vacuum pump 9 first extracts the air in the negative pressure box 8, and discharges it to the outside through the exhaust pipe 12, so that a vacuum state is formed in the negative pressure box 8. The manipulator 1 drives the stepper motor 2 to move, and the stepper motor 2 can drive the fixed rod 3 to rotate, so as to adjust the angle of the adjustment member 4, which is convenient for sucking the workpiece. The set dual-axis motor 41 can drive the screw rod 42 to rotate, thereby synchronously driving the two movable plates 43 to move, so that the distance between the two suction cups 53 can be adjusted, which is convenient for sucking workpieces of different sizes. The set limit block 44 can prevent the movable plate 43 from falling off due to excessive movement, and the set limit plate 7 can limit the air supply pipe 6.

[0034] Working principle: the manipulator 1 drives the stepper motor 2 to move, and the stepper motor 2 can adjust the angle of the adjusting member 4. After the manipulator 1 drives the two suction cups 53 to contact the outer surface of the workpiece, it pushes the adjusting member 4 toward the workpiece again, so that the suction cup 53 can push the movable tube 52 to move, and the movable tube 52 drives the movable ring 56 and the fixed ring 55 to separate when moving. The vacuum air pressure in the negative pressure box 8 extracts the air in the connecting tube 5 through the air supply pipe 6, and extracts the air in the suction cup 53 to achieve the effect of adsorbing the workpiece. When the manipulator 1 moves the workpiece, the spring 54 loses the external pressure. Under the effect of the elastic reset of the spring 54 itself, it will push the suction cup 53 to move, so that the movable ring 56 moves to fit the fixed ring 55 and seals the through hole 57, thereby reducing the leakage of the suction cup 53 and improving practicality. The dual-axis motor 41 can drive the screw rod 42 to rotate, thereby synchronously driving the two movable plates 43 to move, and the distance between the two suction cups 53 can be adjusted.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
