Detailed ways

The present invention will be described in detail below in conjunction with the accompanying drawings.

As shown in the structural diagram of the present invention in Figure 1, the present invention provides a loading and unloading manipulator for stamping, including a support 1, a lifting motor 3 is vertically fixed on the bottom plate 2 of the support 1, and the lifting motor 3 The output end of the drive screw 4 is connected to the drive screw 4, and the drive nut 5 is set on the drive screw 4. The drive nut 5 is fixed on the lifting plate 6, and the driving guide rods are respectively fixed on the corners of the lifting plate 6. 7. The driving guide rod 7 passes through the top of the support 1 and is installed with a fixed plate 8, on which a fixed support 9 is installed, and on the fixed support 9, two rows of driving rollers 10 are installed horizontally, A mechanical arm 11 is slidably connected between the two rows of driving rollers 10 , and a plurality of mechanical hands are uniformly arranged at the front end of the mechanical arm 11 .

Auxiliary guiding devices are respectively installed on both sides of the bracket 1, and the auxiliary guiding devices respectively include connecting plates 12, on which a driving gear 13 is horizontally installed, and the driving gear 13 is vertically meshed and connected with The gear rod 14 is fixedly mounted with an auxiliary support 15 on the top of the gear rod 14 , and two rows of auxiliary rollers 16 are laterally arranged on the auxiliary support 15 . The spacing between the auxiliary rollers 16 matches the height of the mechanical arm 11 .

Described manipulator comprises mounting plate 17, fixed disk 18 and suction cup 19, and described mounting plate 17 is fixed on the side of mechanical arm 11, and described fixed disk 18 is vertically installed on the side of mounting plate 17, is connected on the bottom surface of described fixed disk 18 There are 20 suction cups.

The driving guide rod 7 is connected with the support 1 through the guide sleeve 20 in an up-and-down transmission manner.

The working process of this example: when the loading and unloading manipulator for stamping provided by the present invention is performing the action of taking materials, the lifting motor 3 starts, drives the driving screw mandrel 4 to rotate, and drives the driving screw mandrel 4 to be sleeved on the driving screw mandrel 4 after rotating. The driving nut 5 on the top moves downward along the driving screw 4. Since the driving nut 5 is fixed on the lifting plate 6, the driving nut 5 moves downward while driving the lifting plate 6 to move downward together. At this time, the lifting plate 6 will also move downward. Drive the drive guide rod 7 fixed on the corner to move downward, the drive guide rod 7 is driven up and down through the guide sleeve 20 and the bracket 1, and the drive guide rod 7 moves downward to drive the fixed plate 8 on the top to move downward. 8 is equipped with a fixed support 9, and the downward movement of the fixed plate 8 drives the fixed support 9 to move downward. On the fixed support 9, two rows of driving rollers 10 are horizontally installed, and the two rows of driving rollers 10 drive the mechanical arm 11. Move down and carry out the retrieving action by the manipulator. After the manipulator completes the reclaiming action, the two rows of driving rollers 10 installed horizontally on the fixed support 9 rotate to drive the mechanical arm 11 to move laterally. When the lateral action is completed, the manipulator The plate to be stamped is placed in the area to be stamped through the mounting plate 17, the fixed plate 18 and the suction cup 19, so that a stable and stable lifting force can be provided, and the buffer force is small, so that the manipulator can effectively and safely grab the workpiece.

At the same time, auxiliary guides are respectively installed on both sides of the support 1, and two rows of auxiliary rollers 16 are horizontally arranged on the auxiliary support 15, which can move in the lateral direction and play an auxiliary role in straightening, so that the mechanical arm 11 is Wherein the movement is more stable and stable. A drive gear 13 is installed horizontally on the connecting plate 12. The drive gear 13 is vertically meshed with a gear rod 14, which can ensure the high movement precision of the mechanical arm 11 and prolong its service life.
