[0014] 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.
[0015] Reference Figure 1, the utility model provides an embodiment: a needle suction cup with high safety, including an adsorption air inlet 1 and a release air inlet 2, the adsorption air inlet 1 is one of the air inlet points of the needle suction cup, and is used to introduce compressed air in the adsorption stage, and the air inlet is designed to withstand the inflow of air with a certain pressure to ensure sufficient air flow to drive the internal mechanical components, and the release air inlet 2 is another key air inlet point, which is dedicated to introducing compressed air in the release stage. It can also withstand a certain pressure and allow compressed air to flow in when the adsorption needs to be released. The left and right sides of the adsorption air inlet 1 are fixedly connected with adsorption air inlet ducts 3, and the bottoms of the two adsorption air inlet ducts 3 are fixedly connected with downward pressure chambers 4. The adsorption air inlet duct 3 is a channel connecting the adsorption air inlet 1 and the downward pressure chamber 4, which guides the compressed air from the adsorption air inlet The air from the air inlet 1 flows into the downward pressure chamber 4, providing necessary air pressure support for the adsorption action. The downward pressure chamber 4 is used to accommodate the piston 7 and perform energy conversion of compressed air. When the compressed air enters, the downward pressure chamber 4 will push the piston 7 to move downward, thereby initiating the adsorption action. The left and right sides of the release air inlet 2 are fixedly connected with the release air inlet duct 5. The release air inlet duct 5 is a channel connecting the release air inlet 2 and the lifting chamber 6. In the release stage, it guides the compressed air to flow from the release air inlet 2 to the lifting chamber 6, providing necessary air pressure support for the release action. The tops of the two release air inlet ducts 5 are fixedly connected with the lifting chamber 6. The lifting chamber 6 is used to receive compressed air and act on the piston 7 in the release stage. After the compressed air enters the lifting chamber 6, it will push the piston 7 to move upward, thereby prompting the steel needle 11 to retract;
[0016] The interiors of the two downward pressure chambers 4 are both slidably connected with pistons 7, and the exteriors of the pistons 7 are slidably connected to the interiors of the upward lifting chambers 6. The pistons 7 are the core moving parts of the needle suction cups. The design of the pistons 7 enables them to slide up and down between the downward pressure chambers 4 and the upward lifting chambers 6 in a sealed manner, thereby transmitting force during adsorption and release. The far sides of the two pistons 7 are both fixedly connected with piston connecting rods 8, and the exteriors of the piston connecting rods 8 are slidably connected to the interiors of the downward pressure chambers 4. The function of the piston connecting rods 8 is to transmit the linear motion of the pistons 7 to the needle seat 9, thereby controlling the extension and retraction of the steel needle 11. The far sides of the two piston connecting rods 8 are both provided with There are adjustment components, both of which include needle seats 9. The adjacent sides of the two needle seats 9 are fixedly connected to the distant sides of the two piston connecting rods 8. Adjustment nuts 10 are respectively arranged inside the two needle seats 9. The needle seats 9 and the adjustment nuts 10 are responsible for fine-tuning the extension of the steel needle 11 to adapt to objects of different thicknesses. By rotating the adjustment nuts 10, the position of the needle seat 9 can be changed, thereby accurately controlling the stroke of the steel needle 11. The adjacent sides of the bottoms of the two adjustment components are fixedly connected with steel needles 11. The steel needles 11 are the final actuators of the needle suction cups, which are fixed to the adjacent sides of the bottoms of the adjustment components. In the adsorption stage, the steel needles 11 extend to grasp the surface of the object; in the release stage, the steel needles 11 are retracted to detach from the surface of the object. The precise control of the steel needles 11 ensures the efficient and safe operation of the suction cup.
[0017] Working principle: compressed air is introduced into the adsorption air inlet 1, and no compressed air is introduced into the release air inlet 2. The compressed air enters the downward pressure chamber 4 through the adsorption air inlet duct 3, pushing the piston 7 downward, and the piston 7 drives the piston connecting rod 8 and the needle seat 9 downward to extend the steel needle 11 to achieve adsorption. The extension stroke of the steel needle 11 can be controlled by adjusting the nut 10. Compressed air is introduced into the release air inlet 2 and the compressed air introduced into the adsorption air inlet 1 is disconnected at the same time. The compressed air enters the upward lifting chamber 6 through the release air inlet duct 5, pushing the piston 7 upward, and the piston 7 drives the piston connecting rod 8 and the needle seat 9 upward to retract the steel needle 11 to achieve release.
[0018] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
