Description

Technical Field

[0001] This utility model relates to the field of gas container connection technology, and in particular to a gas cylinder connector disassembly and assembly device. Background Technology

[0002] A gas cylinder is a container for storing gases. In the semiconductor manufacturing industry, chip production involves hundreds of processes, which require a large amount of specialty gases. These specialty gases need to be stored in gas cylinders. Most of these specialty gases are flammable, explosive, highly toxic, or corrosive. To ensure the safe transport and use of these hazardous gases, semiconductor plants install electronic specialty gas systems, equipped with specialized equipment such as electronic specialty gas cabinets (GC), gas distribution boxes (VMB), and specialty gas leak monitoring alarms.

[0003] However, the current application scenarios all involve manual replacement of special gas cylinders. These special gases are flammable, explosive, highly toxic, and corrosive, and there are risks involved in manual replacement operations. In particular, there are significant risks in manually installing and removing cylinder connectors, as well as risks such as installing the wrong type of cylinder and gas leakage. Utility Model Content

[0004] This utility model aims to solve the above problems and provides a gas cylinder connector disassembly and assembly device, the technical solution of which is as follows:

[0005] A gas cylinder connector assembly / disassembly device includes a connector assembly / disassembly base, a connector moving mechanism, and a connector rotating mechanism. The connector assembly / disassembly base is fixedly disposed relative to the gas cylinder. The connector moving mechanism is fixedly mounted on the connector assembly / disassembly base. The connector rotating mechanism is slidably disposed on the connector moving mechanism, and the sliding direction is parallel to the connector axis. The connector rotating mechanism includes a connector connecting seat. The connector connecting seat has a connector connecting hole on the side facing the connector. The inner circumferential surface shape of the connector connecting hole is consistent with the outer circumferential surface shape of the connector. When the connector is inserted into the connector connecting hole, the connector connecting seat and the connector rotate synchronously. The connector connecting seat and the connector's central axis are collinear, and the connector connecting seat rotates around its central axis.

[0006] Based on the above scheme, the connector moving mechanism is provided with a connection position and a disassembly position. The connection position is located on the side closer to the gas cylinder, and the disassembly position is located on the side farther away from the gas cylinder. When the connector rotating mechanism is in the connection position, the connector in the connector connecting seat is connected to the connector mounting position on the gas cylinder, or the connector connecting seat is sleeved on the outside of the connector on the gas cylinder. When the connector rotating mechanism is in the disassembly position, the connector connecting seat is separated from the connector on the gas cylinder, or the connector connecting seat and the connector are separated from the gas cylinder.

[0007] Preferably, the connector moving mechanism includes a first linear motor, a first slide rail, and a first slide table. The first slide rail is fixedly installed on the connector assembly / disassembly base and extends along the connector axial direction. The first linear motor drives the first slide table to move on the first slide rail, and the connector rotating mechanism is fixedly installed on the first slide table.

[0008] Preferably, the joint rotation mechanism further includes a first rotary motor and a rotary transmission mechanism, wherein the first rotary motor drives the joint connector to rotate through the rotary transmission mechanism.

[0009] Preferably, it also includes a connector disassembly and assembly sensor, which is positioned facing the gas cylinder and detects the position of the connector mounting position on the gas cylinder and the distance from the connector mounting position. The connector disassembly and assembly sensor is communicatively connected to the connector moving mechanism and the connector rotating mechanism.

[0010] Preferably, the cross-section of the connector connection hole is a regular polygon.

[0011] Preferably, the connector mounting base is provided with mounting holes.

[0012] Preferably, the first slide rail is fixedly connected to the two ends of the first limiting block, and the first slide table moves between the two first limiting blocks.

[0013] The beneficial effects of this utility model are as follows: by detecting the position and distance of the gas cylinder connector through the connector disassembly and assembly sensor, the connector connecting seat moves relative to the gas cylinder, ensuring that the connector connecting seat and the gas cylinder are properly matched; by driving the rotation transmission mechanism, the connector connecting seat and the connector to rotate through the first rotation mechanism, the installation and disassembly process of the gas cylinder connector is completed, replacing the traditional manual disassembly and assembly operation of the connector, reducing the risk of human operation, and providing protection for the personal safety of the operators.

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0018] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0019] In the description of this utility model, it should be understood that the terms "center," "length," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," and "inner," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0020] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0021] The gas cylinder structure adapted to this solution is as follows: Figure 3 As shown, a connector connection position is provided on the upper part of the gas cylinder 20, and a connector 201 is connected to the connector connection position. The connector 201 is threadedly connected to the connector connection position.

[0022] like Figure 1 and Figure 2 As shown, a gas cylinder connector assembly / disassembly device includes a connector assembly / disassembly base 81, a connector moving mechanism, and a connector rotating mechanism. The connector assembly / disassembly base 81 is fixedly disposed relative to the gas cylinder 20, and the connector assembly / disassembly base 81 is provided with mounting holes for fixed connection.

[0023] The connector moving mechanism is fixedly mounted on the connector disassembly and assembly base 81. The connector rotating mechanism is slidably mounted on the connector moving mechanism, and the sliding direction is parallel to the axial direction of the connector 201. The connector rotating mechanism includes a connector connecting seat 833. The connector connecting seat 833 has a connector connecting hole on the side facing the connector 201. The inner circumferential surface shape of the connector connecting hole is consistent with the outer circumferential surface shape of the connector 201. When the connector 201 is inserted into the connector connecting hole, the connector connecting seat 833 rotates synchronously with the connector 201. The connector connecting seat 833 and the central axis of the connector 201 are collinear, and the connector connecting seat 833 rotates around its central axis. Preferably, the cross-section of the connector connecting hole is a regular polygon, and can be selected as a regular hexagon.

[0024] The connector moving mechanism is provided with a connection position and a disassembly position. The connection position is located on the side closer to the gas cylinder 20, and the disassembly position is located on the side farther away from the gas cylinder 20. When the connector rotating mechanism is in the connection position, the connector 201 in the connector connecting seat 833 is connected to the connector mounting position of the gas cylinder 20, or the connector connecting seat 833 is sleeved on the outside of the connector 201 on the gas cylinder 20. When the connector rotating mechanism is in the disassembly position, the connector connecting seat 833 is separated from the connector 201 on the gas cylinder 20, or the connector connecting seat 833 and the connector 201 are separated from the gas cylinder 20.

[0025] When installing connector 201, connector 201 is placed inside connector base 833. Connector base 833 moves connector 201 from the disassembly position along the axis of connector 201 to the connection position. Connector rotation mechanism drives connector base 833 and connector 201 to rotate. At the same time, connector moving mechanism moves connector base 833 closer to gas cylinder 20 until connector 201 is installed on gas cylinder 20. When disassembling connector 201, connector base 833 moves from the disassembly position to the connection position and is fitted over connector 201. Connector rotation mechanism drives connector base 833 and connector 201 to rotate. At the same time, connector moving mechanism moves connector base 833 further away from gas cylinder 20 until connector 201 is detached from gas cylinder 20. Connector base 833 moves connector 201 back to the disassembly position, completing the disassembly of connector 201.

[0026] Preferably, the system further includes a connector installation / removal sensor 84, which is positioned facing the gas cylinder 20 and detects the position of the connector mounting position on the gas cylinder 20 and the distance from the mounting position. The connector installation / removal sensor 84 is communicatively connected to the connector moving mechanism and the connector rotating mechanism. When installing or removing the connector 201, the connector installation / removal sensor 84 first identifies the presence or absence of the gas cylinder 20 and determines the distance between the connector connector 833 and the connector mounting position. After the determination is completed, the aforementioned installation or removal actions are performed.

[0027] Preferably, the connector moving mechanism includes a first linear motor 821, a first slide rail 822, and a first slide table 824. The first slide rail 822 is fixedly mounted on the connector mounting / dismounting base 81 and extends axially along the connector 201. The first linear motor 821 drives the first slide table 824 to move on the first slide rail 822. The connector rotating mechanism is fixedly mounted on the first slide table 824. First limiting blocks 823 are fixedly connected to both ends of the first slide rail 822, and the first slide table 824 moves between the two first limiting blocks 823.

[0028] The connector rotation mechanism further includes a first fixed seat 834, which is fixedly connected to the first slide 824. The connector rotation mechanism also includes a first rotary motor 831 and a rotary transmission mechanism 832. The first rotary motor 831 drives the connector connecting seat 833 to rotate through the rotary transmission mechanism 832. The connector connecting seat 833 is rotatably mounted on the first fixed seat 834.

[0029] The present invention has been described above by way of example, but the present invention is not limited to the specific embodiments described above. Any modifications or variations made based on the present invention shall fall within the scope of protection claimed by the present invention.
