The horizontal cylinder 7 drives the sliding plate 13 to move laterally, so that the pressing mechanism installed at the lower part of the sliding plate 13 can also move horizontally. The moving cylinder is controlled by solenoid valves to control air intake and shut-off.
[0018] see Figure 1~3 As shown, the pressing mechanism of the present invention includes a ball head pressing rod 17 and a screw picking and clamping mechanism. The bottom of the ball head pressing rod 17 is provided with a guide shaft and a shaft shoulder connected to the end face of the ball head 25. The arm drives the upper mold assembly to move down while picking up the dimming screw 5 while pressing the ball head 25 into the ball head frame 18. see Figure 1~3 As shown, the screw picking and clamping mechanism of the present invention includes at least two guide posts 9, a movable plate 14, a grabbing seat 15 and a grabbing cylinder 24. Each guide post 9 and a ball head pressing rod 17 are mounted on the sliding plate 13, at least two A guide sleeve 10 is installed on the corresponding guide post 9 and connected with the movable plate 14. Each guide post 9 of the present invention is installed at the diagonal of the movable plate 14, or each guide post 9 is installed at the four corners of the movable plate 14, The spring 11 is sleeved on the guide post 9 and located on the upper part of the guide sleeve 10. Through the elastic force of the spring 11, when the dimming screw 5 contacts the ball head 25 during the downward movement of the screw picking and clamping mechanism, the dimming screw 5 is provided with A certain buffering force enables the dimming screw 5 to reliably contact the ball head 25 and rotate into the ball head 25 smoothly. see Figure 1~3 As shown, in the present invention, a stop ring or stop pin for axially limiting the guide sleeve 10 is provided at the lower part of the guide post 9, and the guide sleeve 10 cannot be separated from the guide post 9 through the stop ring or the stop pin. see figure 2 As shown, the gripping seat 15 installed on the movable plate 14 of the present invention is provided with a vertical hole for placing the dimming screw, the gripping cylinder 24 is installed on one side of the gripping seat 15, and the piston rod of the gripping cylinder 24 is The vertical holes are connected. When the lateral movement mechanism drives the grasping base 15 to move down to the screw base 3, the grasping cylinder 24 moves to push the dimming screw 5 on the grasping base 15, and when the grasping base 15 moves to the rotating platform The upper part of 19 is controlled by the lifting arm of the press to move the upper mold assembly downward, and the dimming screw 5 is placed in the ball head hole, and the rotating platform 19 is driven to rotate by the motor 22 on the ball head frame positioning and rotating mechanism. In the process of moving the parts downwards, screw the dimming screw 5 into the ball head 25. When the displacement sensing mechanism senses that the dimming screw reaches the assembly height, it sends a letter, and the grabbing cylinder 24 loosens the dimming screw 5, and the grabbing cylinder The solenoid valve controls the intake and cut-off.

Inside, the horizontally moving cylinder drives the slide plate 13 to make the ball head pressing rod 17 correspond to the ball head 25, and the grab seat 15 is located on the upper part of the dimming screw 5. The upper mold assembly is driven to move down by the lifting arm of the press, and the ball head presses The rod 17 presses the ball head 25 into the ball head frame 18, and at the same time, the dimming screw 5 stretches into the vertical hole of the grasping base 15. At this time, the upper limit column 2 and the lower limit column 5 are connected, and the grasping cylinder 24 moves The dimming screw 5 rests on the grasping base 15; the press lifting arm drives the upper mold assembly to move up, and then the slide plate 13 is driven to move by the transverse cylinder 7 so that the grasping base 15 is located on the upper part of the rotating platform 19, and the press lifts The arm descends to drive the upper die assembly to move down. The motor 22 acts to drive the rotating platform 19, the ball head frame 18 and the ball head 25 to rotate. At this time, the displacement sensing mechanism starts to work. When the dimming screw 5 contacts the ball head 25, it passes The spring 11 provides a certain buffer force, so that the dimming screw 5 is reliably screwed into the ball head 25. When the dimming screw 5 is screwed into the set position, the displacement sensing mechanism 20 sends a signal, the motor 22 stops, and grabs the cylinder. 24 Loosen the dimming screw, at this time the upper limit post is connected with the 2 lower limit post 5, and the assembled ball head dimming assembly is taken out of the rotating platform 19, and then the next assembly cycle will be entered.
