Description

Technical Field

[0001] The invention relates to the technical field of high-speed material taking and placing equipment, and in particular to a split-type air slip ring structure. Background Art

[0002] Gas slip ring, also known as gas rotary joint or gas transmission rotary joint, is a rotary connection device specially used to transmit gas signals. It is widely used in automation equipment, robots, material handling systems and other fields. It is mainly used to transmit gas signals between rotating parts and fixed parts, such as control signals, sensor data or other gas information that needs to be transmitted in real time. Traditional gas slip rings usually consist of the following parts:

[0003] 1. Shell: The shell of the gas slip ring is usually made of metal material with high mechanical strength and wear resistance to protect the internal rotating parts from external influences.

[0004] 2. Rotating part: The rotating part contains the internal gas channel and sealing structure, which allows the device to transmit gas signals while rotating while maintaining the stability of the connection.

[0005] 3. Gas channel: The key part of the gas slip ring is the gas channel, which is responsible for transmitting gas signals during the rotation process. These gas signals can be control signals, sensor data or other gas information that needs to be transmitted in real time.

[0006] Although traditional gas slip rings perform well in many applications, they have obvious limitations in some complex working conditions, especially when simultaneous rotation and lifting actions are required:

[0007] The traditional one-piece air slip ring can only realize a single rotation function and cannot perform lifting and lowering movements while rotating. This limits its application in multi-station and complex motion modes. The overall height of the one-piece air slip ring is relatively large (for example, the total height of the 8-station slip ring is 126mm), which makes it difficult to install and use in some applications with limited space. When the suction nozzles at the material picking position and the material discharge position are subjected to force at the same time, the one-piece slip ring is prone to severe wear, affecting its service life and performance. The cost of traditional one-piece slip rings is relatively high, especially for multi-station applications, the price is often more than 800 yuan, which increases the overall cost of the equipment. Summary of the invention

[0008] The main purpose of the present invention is to provide a split air slip ring structure, which aims to solve the problem that the integrated air slip ring can only realize a single rotation function and cannot perform lifting and lowering actions while rotating. This limits its application in multi-station and complex motion modes. The overall height of the integrated air slip ring is relatively large (for example, the overall height of the 8-station slip ring is 126mm), which is difficult to install and use in some applications with limited space. When the suction nozzles at the material picking position and the material discharging position are subjected to force at the same time, the integrated slip ring is prone to severe wear, affecting its service life and performance.

[0009] In order to achieve the above-mentioned object of the invention, the first aspect of the present invention proposes a split gas slip ring structure, comprising:

[0010] An air intake base, wherein the air intake base has an air distribution annular air passage;

[0011] An airway gasket, which fits tightly with the air inlet base and is used to maintain an unobstructed airway;

[0012] A rotating body, fixedly connected to the airway gasket, for completing rotation and lifting actions in a limited space;

[0013] A guide column, slidably connected to the air inlet base, for guiding the movement of the rotating body;

[0014] The spring is installed on the guide column and is used to provide elastic force to keep the air intake base and the airway gasket in close contact at all times to ensure air tightness.

[0015] Furthermore, a plurality of workstation air inlet connectors are fixedly mounted on the side wall of the rotating body, and the workstation air inlet connectors are connected to the suction nozzle via an air pipe.

[0016] Furthermore, the spring and the guide column enable the air slip ring structure to maintain a close fit between the internal components and prevent air leakage when completing the rotation and lifting actions.

[0017] Furthermore, the airway gasket is made of wear-resistant material, preferably nylon, to enhance durability and sealing performance.

[0018] Furthermore, the air inlet base is provided with a vacuum air inlet and a vacuum breaking air inlet.

[0019] Furthermore, the vacuum-breaking air inlet is used to allow air to enter at the material discharge level, so as to release the vacuum state of the suction nozzle, thereby achieving the release of the material.

[0020] Furthermore, the rotating body is fixedly connected to the cam divider output shaft through the turret and the middle clamp, so as to synchronously complete the rotation and lifting actions during the operation of the cam divider while maintaining the connectivity of the gas path.

[0021] Furthermore, there are two guide columns, which are symmetrically distributed on the vertical line of the axis of the material taking position and the material discharging position, and are used to provide uniform guiding force and supporting force to ensure the stability of the rotating body during the lifting and rotation process.

[0022] Furthermore, the arc length of the gas distribution annular air duct is 20 mm to 80 mm, and the angle range is 30° to 180°.

[0023] Furthermore, when the split air slip ring structure is applied to automation equipment, the split air slip ring structure is linked with the cam divider to realize the material picking and discharging functions, which solves the problem of slip ring gas distribution rotation and lifting without affecting work efficiency.

[0024] Beneficial effects:

[0025] The split air slip ring structure of the present invention is derived based on the content of the patent claim 1 to obtain beneficial effects.

[0026] 1. The present invention decomposes the air slip ring into independent parts such as the air intake base, the airway gasket, the rotating body, the guide column and the spring, and can complete the compound action of rotation and lifting in a limited space. The rotating body can synchronously complete the rotation and lifting during the action of the cam divider, while maintaining the connectivity and air tightness of the air path, solving the problem that the traditional integrated slip ring can only rotate but not lift.

[0027] 2. The present invention is installed on the guide column by a spring, which provides elastic force to keep the air intake base and the airway gasket in close contact at all times to ensure air tightness. Even in complex rotation and lifting movements, gas leakage can be prevented to ensure the stability and reliability of the air path. The annular airway of the air intake base is designed as an arc-shaped airway with adjustable angle, with an arc length of preferably 20mm to 80mm and an angle range of 30° to 180°. It can be adjusted according to the requirements of different workstations and rotation angles to ensure that each workstation can obtain sufficient gas flow, thereby improving the versatility and applicability of the equipment.

[0028] 3. Compared with the one-piece slip ring with the same number of stations, the cost of the present invention is reduced by at least 40%. Specifically, taking 8 stations as an example, the total price of a single set of split slip ring processing parts is about 400 yuan, and the standard parts are 50 yuan, while the price of the general-purpose Murvron slip ring 8 stations is more than 800 yuan. Therefore, the split gas slip ring structure not only reduces the manufacturing cost, but also improves the cost performance.

[0029] 4. The invention adopts a quick disassembly structure through the connection between the airway gasket and the rotating body, which is convenient for maintenance and replacement, simplifies the repair and maintenance process, and reduces maintenance costs and time. Through the design of springs and guide columns, the split air slip ring structure can maintain a close fit between the components during rotation and lifting, reducing wear and tear and extending the service life of the equipment. Especially when the suction nozzles at the material picking and discharge positions are stressed at the same time, the structure can withstand a large load without affecting the service life and performance of the slip ring.

[0030] 5. The present invention sets a plurality of independent gas channels inside the rotating body, and each channel corresponds to a workstation without interfering with each other, thereby ensuring the independence and stability of the gas path. This enables the structure to flexibly respond to the needs of different workstations, and is particularly suitable for applications with multiple workstations and complex motion modes. When the split air slip ring structure is applied to automation equipment, it can be linked with the cam divider to realize the functions of picking up and discharging materials, which solves the problem of rotation and lifting of the slip ring gas distribution without affecting work efficiency. For example, in the fields of electronic component assembly, food packaging, and pharmaceutical manufacturing, the structure can ensure the precise handling and placement of materials, and improve production efficiency and product quality.

[0042] Reference Figure 1-Figure 4 An embodiment of the present invention provides a split air slip ring structure, comprising:

[0043] An air intake base 3, wherein the air intake base 3 has an air distribution annular air passage 31;

[0044] The airway gasket 2 is tightly fitted with the air inlet base 3 to maintain the airway unobstructed;

[0045] The rotating body 1 is fixedly connected to the airway gasket 2 and is used to complete the rotation and lifting action in a limited space;

[0046] A guide column 5 is slidably connected to the air inlet base 3 and is used to guide the lifting and lowering action of the rotating body 1 so that the base can only be lifted and lowered but not rotated;

[0047] The spring 4 is installed on the guide column 5 to provide elastic force to keep the air intake base 3 and the airway gasket 2 in close contact at all times to ensure air tightness.

[0048] The airway gasket 2 is made of wear-resistant material, preferably nylon, to enhance durability and sealing performance.

[0049] In this embodiment, the air inlet base 3 has an air distribution annular air duct 31. The air duct gasket 2 fits tightly with the air inlet base 3 to maintain the smoothness of the air path. The contact surface between the air duct gasket 2 and the air inlet base 3 ensures smoothness and flatness, ensuring that the two can fit tightly, further enhancing the sealing performance between the air inlet base 3 and the rotating body 1, preventing gas leakage, and ensuring the stability and reliability of the air path. The rotating body 1 is fixedly connected to the air duct gasket 2 and can complete rotation and lifting actions in a limited space. The guide column 5 is slidably connected to the air inlet base 3 to guide the movement of the rotating body 1. There are two guide columns 5, which are symmetrically distributed on the vertical line of the axis of the material taking position and the material discharging position, and are used to provide uniform guiding force and supporting force to ensure the stability of the rotating body 1 during the lifting and rotation process, reduce wear and extend the service life.

[0050] During installation, the spring 4 should be pre-compressed to a certain extent so that the spring 4 is always in a compressed state. The spring 4 rebounds so that the airway gasket 2 and the air intake base 3 always remain in contact.

[0051] Compared with the one-piece slip ring with the same number of stations, the cost of this structure is reduced by at least 40%. Specifically, taking 8 stations as an example, the total price of a single set of split slip ring processing parts is about 400 yuan, and the standard parts are 50 yuan, while the general-purpose Murvron slip ring 8-station price is more than 800 yuan. Therefore, the split gas slip ring structure not only reduces the cost, but also improves the cost performance.

[0052] In addition, the equipment can withstand the situation where the suction nozzles at the material picking position and the material discharging position are subjected to force at the same time without affecting the service life and performance of the slip ring. This design solves the problem that the traditional integrated slip ring is easy to wear and affect the service life under force, and improves the overall reliability and durability of the equipment.

[0053] Optionally, a plurality of station air inlet connectors 11 are fixedly mounted on the side wall of the rotating body 1, and the station air inlet connectors 11 are connected to the suction nozzle via an air pipe.

[0054] It should be noted that a number of station air inlet connectors 11 are fixedly installed on the side wall of the rotating body 1. These connectors are connected to the suction nozzle through air pipes to ensure that each station can obtain an independent and stable air supply. A plurality of independent gas channels are arranged inside the rotating body 1, each channel corresponding to a station, and they do not interfere with each other, ensuring the independence and stability of the gas path.

[0055] The spring 4 and the guide column 5 enable the air slip ring structure to maintain a close fit between the internal components and prevent air leakage when completing the rotation and lifting actions.

[0056] The spring 4 is mounted on the guide column 5, providing elastic force to keep the air intake base 3 and the airway gasket 2 in close contact at all times to ensure air tightness. Through the design of the spring 4 and the guide column 5, the air slip ring structure can still maintain a close fit between the internal components and prevent air leakage when completing the rotation and lifting action.

[0057] The air inlet base 3 is provided with a vacuum air inlet 32 ​​and a vacuum breaking air inlet 33, and the vacuum breaking air inlet 33 is used to let in air when the material is discharged to release the vacuum state of the suction nozzle, thereby releasing the material.

[0058] The rotating body 1 is fixedly connected to the cam divider output shaft through a turret and a hoop in the middle, and is used to synchronously complete the rotation and lifting actions during the operation of the cam divider while maintaining the connectivity of the gas path.

[0059] The arc length of the annular gas distribution channel 31 is 20 mm to 80 mm, and the angle range is 30° to 180°.

[0060] The annular gas channel 31 is designed as an adjustable arc-shaped gas channel according to the number of workstations and the rotation angle. The preferred arc length is 20 mm to 80 mm and the angle range is 30° to 180°. For 8-workstation applications, an angle range of 90° to 120° is recommended to ensure smooth transitions between each workstation and adapt to different workstation layouts.

[0061] In one embodiment, when the split air slip ring structure is applied to automation equipment, the split air slip ring structure is linked with a cam divider to realize the material picking and discharging functions, which solves the problem of slip ring gas distribution rotation and lifting without affecting work efficiency.

[0062] It should be noted that in the automated production line, this structure can be linked with the cam divider to realize the functions of picking up and discharging materials, which solves the problem of rotation and lifting of the slip ring gas distribution without affecting work efficiency. For example, in the fields of electronic component assembly, food packaging, and pharmaceutical manufacturing, this structure can ensure the precise handling and placement of materials, improve production efficiency and product quality. In material handling equipment, this structure can perform multi-station rotation, separate gas distribution, and up and down movement, which is suitable for complex material handling tasks. For example, in automatic sorting systems, robot gripping devices, and other occasions, this structure can flexibly respond to the needs of different stations and ensure that each station has a stable supply of gas.

[0063] In screening and testing equipment, this structure can cooperate with the suction nozzle to grab and release materials to ensure the accuracy and efficiency of the testing process. For example, in quality inspection, size measurement and other links, this structure can quickly switch the air path to achieve precise control of materials.

[0064] Furthermore, the split air slip ring structure is mainly used in automation equipment, especially in complex working conditions that require multi-station rotation, separate air distribution, and up and down movement. The working principle is as follows:

[0065] The cam divider is in a high position, and the rotating body 1 is fixedly connected to the cam divider output shaft through the turret and the middle clamp. At this time, the suction nozzle has been connected to the vacuum air source. After starting, the cam divider drops to the material taking position, the suction nozzle sucks the material, and then starts to rotate as the output shaft rises to a high position, and rotates a fixed angle according to the number of workstations, repeating the action of descending, sucking, rising, and rotating.

[0066] Then, when the cam divider descends, the spring 4 compresses and pushes back the air base 3, so that the base and the airway gasket 2 always keep in close contact, ensuring the connectivity and air tightness of the air path. Through the arc-shaped airway of the base, the suction nozzle always maintains a vacuum state, adsorbing the material and moving it to the discharge station.

[0067] When the cam divider rotates to the discharge position and then drops to the low position, air is introduced into the vacuum-breaking air inlet 33 to release the vacuum state, and the suction nozzle places the material at the discharge position, returns to the normal pressure state, and rotates to the material taking position to repeat the material taking action.

[0068] Note: The cam divider is in a high position: In the initial state, the cam divider is in a high position. The rotating body 1 is fixedly connected to the cam divider output shaft through the turret and the middle clamp. At this time, the suction nozzle has been connected to the vacuum air source and is ready for material removal. The air distribution annular air duct 31 on the air intake base 3 maintains close contact with the gas channel in the rotating body 1 through the air duct gasket 2 to ensure that the air path is unobstructed. The spring 4 provides elastic force to keep the air intake base 3 and the air duct gasket 2 in close contact at all times to prevent air leakage.

[0069] When the cam divider is lowered to the material fetching position, the rotating body 1 descends together with the cam divider. During this process, the guide column 5 guides the movement of the rotating body 1 to ensure its smooth descent. At the same time, the spring 4 is compressed and pushes back the air intake base 3, so that the base and the airway gasket 2 always maintain close contact, ensuring the connectivity and air tightness of the air path. After reaching the material fetching position, the suction nozzle absorbs the material through the vacuum air source. At this time, the vacuum air inlet 32 ​​on the air intake base 3 continuously provides vacuum pressure to ensure that the suction nozzle can firmly grasp the material. The cam divider drives the rotating body 1 to rise to a high position. As the rotating body 1 rises, the spring 4 gradually returns to its original state and continues to provide elastic force, so that the air intake base 3 and the airway gasket 2 maintain close contact, ensuring the stability and sealing of the air path.

[0070] After reaching the high position, the cam divider drives the rotating body 1 to rotate to the next station according to the preset rotation angle. During the rotation process, the airway gasket 2 effectively prevents gas leakage to ensure that each station can obtain an independent and stable air supply. When the cam divider rotates to the discharge position, the rotating body 1 drops to the low position again. At this time, the vacuum-breaking air inlet 33 allows air to enter to release the vacuum state of the suction nozzle. Specifically, the vacuum-breaking air inlet 33 introduces air into the system, breaks the vacuum environment inside the suction nozzle, and causes the suction nozzle to release the material. After the suction nozzle releases the material, the material is placed on the discharge position. At this time, the system returns to normal pressure and prepares for the next round of material picking operation.

[0071] The application examples are as follows:

[0072] On the automated production line, the split air slip ring structure can be linked with the cam divider to realize the material picking and unloading functions, which solves the problem of slip ring gas distribution rotation and lifting without affecting work efficiency. For example, in the fields of electronic component assembly, food packaging, and pharmaceutical manufacturing, this structure can ensure the precise handling and placement of materials, improving production efficiency and product quality.

[0073] In material handling equipment, this structure can perform multi-station rotation and individual gas distribution as well as up and down movement, which is suitable for complex material handling tasks. For example, in automatic sorting systems, robot gripping devices and other occasions, this structure can flexibly respond to the needs of different stations and ensure that each station can obtain a stable gas supply.

[0074] In screening and testing equipment, this structure can cooperate with the suction nozzle to grab and release materials to ensure the accuracy and efficiency of the testing process. For example, in quality inspection, size measurement and other links, this structure can quickly switch the air path to achieve precise control of materials.

[0075] After the discharge is completed, the cam divider drives the rotating body 1 back to the high position, and repeats the above-mentioned action cycle of taking in materials, rising, rotating, and discharging materials as needed. During the whole process, the split air slip ring structure always ensures the connectivity and air tightness of the air path, and can maintain stable gas transmission even in complex rotation and lifting actions.
