With the intermittent suction of the suction hose 17 and the intermittent feeding of the motor 8, the material-taking structure can make the robot arm 2 work continuously, avoiding the process of the robot arm 2 taking materials, and effectively improving the working efficiency of the automatic buckle installation equipment.

The provided spring clip 13 can prevent the buckle from falling automatically, so that the buckle can be installed.

[0023] See also Figures 1 to 6The valve core mechanism includes a first communicating groove 20, the interior of the second connecting pipe 18 is connected to the valve box 14 through the first communicating groove 20, the interior of the second connecting pipe 18 is connected to the exhaust hose 19 through the second communicating groove 21, a baffle 22 is installed inside the second communicating groove 21, a vent hole 23 is passed through the middle of the baffle 22, a piston 24 is provided inside the first communicating groove 20, a return spring 25 is installed between the piston 24 and the baffle 22, and a vent groove 26 is equidistantly opened on the ring side of the piston 24, and the end of the piston 24 away from the return spring 25 is fixedly connected to a connecting rod 27, and the connecting rod 27 is located inside the valve box 14. The end is fixedly connected to a valve block 28, and a material passage 29 is passed through the valve block 28 at the position corresponding to the feed pipe 15. A material blocking groove 30 is opened at the top of the valve block 28 near the material passage 29. The inner diameter of the first communicating groove 20 is smaller than the inner diameter of the second communicating groove 21, and the inner diameter of the first communicating groove 20 coincides with the outer diameter of the piston 24, and the piston 24 is elastically connected to the baffle 22 through the return spring 25.

[0024] Working principle: This is an automatic buckle installation device for automobiles. When the automatic buckle installation device is in use, the fan (an existing common device, so it is not shown in the figure, and the existing technology is directly quoted) works to make the suction hose 17 suck the buckle (the vibrating feeder can automatically arrange the buckle neatly. The vibrating feeder is an existing common feeding device. This solution has not improved it, so it is not shown in the figure), and the buckle falls into the inside of the box body 3. The motor 8 drives the first screw rod 5 and the second screw rod 6 on both sides to rotate in opposite directions through the transmission gear 7, and a workpiece groove is formed between the first screw rod 5 and the second screw rod 6, which drives the buckle between the first screw rod 5 and the second screw rod 6 to move toward the discharge pipe 9. After the buckle moves to the discharge pipe 9, the pushing cylinder 11 pushes the buckle out and buckles it on the automobile parts. With the intermittent suction of the suction hose 17 and the intermittent feeding of the motor 8, the material-taking structure can make the robot arm 2 work continuously, avoiding the material-taking process of the robot arm 2, and effectively improving the working efficiency of the automatic buckle installation device. After the buckle falls into the inside of the discharge pipe 9, the spring piece 13 is pressed against the bottom of the buckle, and after the robotic arm 2 drives the discharge pipe 9 to move to the specified position, the telescopic end of the pushing cylinder 11 extends into the inside of the box body 3 and pushes the buckle in the discharge pipe 9 to move downward, so that the buckle pushes the spring piece 13 away and continues to fall, thereby completing the installation of the buckle. The spring piece 13 is provided to prevent the buckle from automatically falling off, so that the buckle can be installed. When the fan is working, the exhaust hose 19 generates suction to form a negative pressure state, which drives the piston 24 to overcome the return spring 25 and move toward the baffle 22. After the opening of the vent groove 26 on the side of the piston 24 moves into the second connecting groove 21, the air flow path is opened, and at the same time, the piston 24 drives the valve block 28 to move through the connecting rod 27, so that the valve The material trough 29 of the block 28 is misaligned with the discharge pipe 15, closing the discharge pipe 15, and then increasing the suction force of the suction hose 17, so that the buckle can be smoothly sucked in and dropped into the valve box 14, so that the bottom of the buckle is against the material blocking groove 30, preventing the buckle from being sucked into the second connecting pipe 18. After the fan stops working, the return spring 25 drives the piston 24 and the valve block 28 to reset, so that the material trough 29 is aligned with the discharge pipe 15, and the buckle falls into the interior of the box body 3 through the material trough 29 and the discharge pipe 15. Through the valve core mechanism, the discharge pipe 15 can be automatically closed or opened when the fan is working, so that the buckle can smoothly enter the interior of the box body 3, so that the buckle automatic installation equipment can automatically take the material, avoiding the robot arm 2 wasting stroke to repeatedly take the material.
