Description

TECHNICAL FIELD

[0001] The application relates to the technical field of cylinder devices, in particular to a Z-axis adsorption carrying high-frequency cylinder with buffering. BACKGROUND

[0002] The high-frequency cylinder is a special pneumatic actuator used in industrial automation to achieve high-frequency and high-speed reciprocating motion. Its design optimizes structure, material and buffering system to meet the requirements of precise control, fast response and durability.

[0003] The background technology of the high-frequency cylinder comes from the increasing demand for high-speed and high-frequency reciprocating motion in industrial automation. It is especially suitable for short-stroke scenarios. The core challenge lies in balancing the motion frequency and buffering performance. Traditional cylinders cannot effectively buffer when the stroke exceeds 50 mm due to excessive impact. Short-stroke cylinders improve response speed by optimizing the pneumatic circuit, such as using fast exhaust valves, reducing load rate (<30%), and selecting electromagnetic valves with short switching time. In addition, the structure adopts a bladder cylinder design, which uses flexible materials to absorb high-frequency impact forces, reducing wear by 70%, extending service life by 50%, and reducing energy consumption and noise. These technical innovations solve the problems of sealing failure, positioning accuracy and equipment wear under high-frequency operation, and promote efficiency improvement in fields such as automobile manufacturing and electronic precision machining.

[0004] However, the current high-frequency cylinder has a high degree of wear and tear in short-stroke shock, a low service life, and a large overall size, which limits its position in actual use scenarios, has many wire harnesses, and has a less refined overall structure density. Over time, it can cause the entire piece to loosen. SUMMARY

[0030] Reference Appendix Figures 1-3 This is a schematic diagram of the overall structure of a high-frequency cylinder with buffer for Z-axis adsorption and conveying in one embodiment of this application.

[0031] Example 1

[0032] A high-frequency cylinder with buffer for Z-axis adsorption and conveying, comprising:

[0033] The housing includes a solenoid valve 2, a housing 1, and a magnetic ring 5;

[0034] The solenoid valve 2 is located on one side of the housing 1, and the magnetic ring 5 is located on the other side of the housing 1. The magnetic ring 5 is embedded in the housing 1.

[0035] The center of the outer shell 1 is hollow;

[0036] A negative pressure adsorption assembly, comprising a negative pressure interface 4 and a piston rod 6;

[0037] The negative pressure port 4 is connected to one end of the piston rod 6, and the other end of the piston rod 6 extends through the center of the outer shell 1 to the other end of the outer shell 1. The piston rod 6 has a through groove 105, and the negative pressure port 4 is connected to the through groove 105.

[0038] A high-frequency vibration assembly, comprising a positive pressure interface 3, a piston chamber, a first positive pressure connecting pipe 104, and a second positive pressure connecting pipe 103;

[0039] The positive pressure port 3 is located at one end of the outer shell 1. The positive pressure port 3 is guided into the solenoid valve 2 through the first positive pressure connecting pipe 104 opened inside the outer shell 1. The piston chamber is located at the center of the outer shell 1. The solenoid valve 2 is connected to the piston chamber through the second positive pressure connecting pipe 103. The piston rod 6 moves up and down in the piston chamber through the positive pressure impact or leakage of the second positive pressure connecting pipe 103.

[0040] The piston rod 6 is fixedly connected to the outer shell 1 at the end near the negative pressure port 4, and the negative pressure port 4 and the positive pressure port 3 are located on the same side.

[0041] Specifically,

[0042] First, negative pressure is connected to negative pressure port 4. The negative pressure will enter from negative pressure port 4, then enter from through groove 105 inside piston rod 6, and finally adsorb objects from the other end of piston rod 6. This is the principle of adsorption.

[0043] During adsorption, to achieve high-frequency vibration, when the negative pressure port 4 is working normally and sucking in an object, positive pressure is connected to the positive pressure port 3. The positive pressure in the positive pressure port 3 enters the first positive pressure connecting pipe 104 inside the outer casing 1 and then enters the P port of the solenoid valve 2. When the solenoid valve 2 is not energized, the P port is closed, and the A and R ports are connected. In this case, positive pressure cannot enter the solenoid valve 2 to proceed to the next step. Therefore, the solenoid valve 2 needs to be energized. When the solenoid valve 2 is energized:

[0044] Port P is connected to Port A. Positive pressure enters the solenoid valve 2 through Port P and exits through Port A into the second positive pressure connecting pipe 103. It then enters the piston chamber at the center of the outer casing 1 through the second positive pressure connecting pipe 103. The piston rod 6 is located in the piston chamber, which is divided into upper and lower spaces. The upper space 101 is the side of the piston rod 6 with spring elasticity, and the lower space 102 is the side of the piston rod 6 without elasticity. The second positive pressure connecting pipe 103 is aligned with the lower space 102 of the piston chamber, that is, the piston rod 6 is located at one end of the product. The lower space 102 of the piston chamber is gradually filled and compressed by the positive pressure. The lower space 102 expands, squeezing the lower space 102 of the piston chamber towards the upper space 101, squeezing the spring end of the upper space 101 of the piston chamber. Therefore, the piston rod 6 will move upward, causing the product end connected to the product to move upward. This is the process of driving the product to rise.

[0045] After the product's upward movement ends, solenoid valve 2 needs to be closed to achieve a non-energized state. When solenoid valve 2 is not energized, port P of solenoid valve 2 is closed, and the positive pressure in positive pressure port 3 cannot enter solenoid valve 2 through port P. Then, ports A and R are connected. When the positive pressure source of port P is cut off, the piston rod 6 in the piston chamber will be pushed back by the elastic potential energy accumulated by the originally compressed spring. That is, the upper space 101 of the piston chamber will be opened by the elastic potential energy of the spring. The piston rod 6 moves downward and squeezes the lower space 102 of the piston chamber. The positive pressure that entered the lower space 102 of the piston chamber before will enter solenoid valve 2 through port A and then be discharged from the vent of port R. At this time, the product moves downward with the piston rod 6. This is the downward movement of the product.

[0046] In summary, the product is continuously attracted to the piston rod 6 through the through groove 105. Then, under the combined action of the positive pressure of the piston rod 6, the piston chamber, and the solenoid valve 2, and the elastic potential energy of the spring on the piston rod 6, it achieves the effect of reciprocating motion of rising and falling. The solenoid valve 2 repeatedly starts and stops to achieve the purpose of reciprocating motion of rising and falling. The cylinder in this application can achieve 100Hz vibration and achieve the purpose of high frequency and long life.

[0047] In this embodiment, an engineering plastic part 106 is also included. The engineering plastic part 106 is disposed at the connection between the inner side wall of the outer shell 1 and the piston rod 6, and the engineering plastic part 106 is located at the other end away from the negative pressure interface 4.

[0048] Since the outer casing 1 is made of metal and the piston rod 6 is also made of metal, metal-to-metal contact will cause rapid wear. Therefore, engineering plastic 106 needs to be added at the connection between the outer casing 1 and the piston rod 6 to improve the product's service life.

[0049] In this embodiment, the piston rod 6 is not in contact with the piston chamber, and the piston rod 6 is limited at the center position of the outer casing 1.

[0050] Specifically, similarly, the piston rod 6 and the piston chamber are not in contact, so there will be no metal-to-metal contact. Furthermore, the positive pressure entering the lower space 102 of the piston chamber is also sufficient to push the lower space 102 of the piston chamber.

[0051] In this embodiment, the piston rod 6 is located at one end of the negative pressure interface 4 and an anti-rotation block 9 is provided at the spring position inside the housing 1.

[0052] Specifically, because the piston rod 6 may rotate during the rising and falling process when it is adsorbing an object, in order to prevent the piston rod 6 from rotating during high-frequency vibration, the position of the rotating block limiting spring is adjusted to prevent the piston rod 6 from rotating.

[0053] In this embodiment, an O-ring 8 is provided at the end of the piston rod 6 where the product is adsorbed.

[0054] Specifically, the O-ring 8 is installed on the piston rod 6. During the upward movement of the piston rod 6, it may collide with the outer shell 1. By setting the O-ring 8, metal-to-metal contact between the piston rod 6 and the outer shell 1 can be avoided, thus improving the service life.

[0055] In this embodiment, the outer casing 1 has a mounting nut 7 at the end where the product is adsorbed. Specifically, the mounting nut 7 allows the cylinder to be installed more conveniently in other devices.

[0056] In summary, because engineering plastic 106 is used to isolate metal-to-metal friction, the lifespan is longer. The piston rod 6 does not use a Y-type seal ring like traditional cylinders, but instead uses a micro-gap zero-friction method, resulting in a higher frequency.

[0057] Piston rod 6 is a hollow rod, or more accurately, a suction rod. By applying negative pressure and attaching a suction cup, it can pick up materials. It can be used to grip materials along the Z-axis. If there is a risk of materials sticking together, the high-frequency vibration mode can be activated to separate the materials, thus serving multiple functions in combination.
