Description

Air tightness detection sealing device and air tightness detection system

Technical Field

The application relates to the technical field of detection, in particular to an air tightness detection sealing device and an air tightness detection system.

Background

The air tightness detection system is used for detecting the air tightness of an object to be detected (such as a water cooling plate). The structure of the air tightness detection system is more, so that the air tightness detection system is larger in size.

Disclosure of utility model

The application mainly solves the technical problem of providing an air tightness detection sealing device and an air tightness detection system, and solves the problem of larger size of the air tightness detection system.

In order to solve the technical problems, the first technical scheme adopted by the application is as follows: the utility model provides a gas tightness detects sealing device, gas tightness detects sealing device includes connecting the shutoff piece, and first casing and the second casing of detachable connection. The first housing and the second housing can be combined in a first direction into a vacuum box having a sealed chamber. The connecting plugging piece is arranged on at least one of the first shell and the second shell; when the first shell and the second shell are combined into the vacuum box, the connecting plugging piece is positioned in the vacuum box, and is connected with a connecting port of the piece to be detected in the vacuum box and plugs the connecting port of the piece to be detected in the vacuum box.

In the airtight detection sealing device, as the connecting plugging piece is directly arranged on at least one of the first shell and the second shell, and in the process of combining the first shell and the second shell to form the vacuum box, the first shell or the second shell drives the connecting plugging piece to plug and seal the connecting port of the piece to be detected, and the piece to be detected is fixed in the vacuum box. Therefore, a driving mechanism in the related art is not required to be arranged in the vacuum box to drive the connecting plugging piece and the limiting mechanism, so that the volume of the vacuum box pair can be reduced, and the total volume of the air tightness detection sealing device is reduced. The air tightness detection sealing device of the embodiment of the disclosure seals the connecting port of the to-be-detected member by utilizing the connecting and plugging member, so that the operation is simple (that is, the operation of a driving mechanism in the related art is not complex); then, when detecting the to-be-detected pieces, the detection time of each to-be-detected piece can be shortened, so that the detection efficiency is improved.

In some embodiments, the connection block is detachably connected with at least one of the first housing and the second housing. In this way, the connection of the blocking element to the vacuum box is facilitated.

In some embodiments, at least one of the first housing and the second housing has a mounting slot; the connecting plugging piece is inserted into the mounting groove. In this way, the closure member is conveniently connected to the first housing and/or the second housing.

In some embodiments, the connection block has an external connection channel that communicates with the lumen of the member to be tested. In this way, the external connection channel with the connecting plug can be connected to an external device outside the vacuum box.

In some embodiments, each connection block comprises a first connection block and a second connection block; the first connecting plugging piece is connected with the first shell, and the second connecting plugging piece is connected with the second shell. The first connecting plugging piece and the second connecting plugging piece are oppositely arranged and respectively plug two connectors of the piece to be detected, which are oppositely arranged.

In this way, one end of the first connecting plugging piece is inserted into the first connecting port of the piece to be detected, and the other end of the first connecting plugging piece is connected with the first shell (for example, the other end of the first connecting plugging piece is inserted into the mounting groove of the first shell); one end of the second connecting plugging piece is inserted into the second connecting port of the piece to be detected, and the other end of the second connecting plugging piece is connected with the second shell (for example, the other end of the second connecting plugging piece is inserted into the mounting groove of the second shell); thereby the piece to be detected is fixed between the other end of the first connecting plugging piece and the other end of the second connecting plugging piece.

In some embodiments, the connection block moves in the first direction in synchronization with the first housing or the second housing. In the process that the first shell and the second shell form the vacuum box, the connecting plugging piece is inserted into the connecting port of the piece to be detected and is connected with the first shell and/or the second shell.

In some embodiments, the direction of extension of the connection block is a first direction; after the to-be-detected piece is arranged in the vacuum box, the air tightness detection sealing device further comprises an adapter piece under the condition that the direction of the connecting port of the to-be-detected piece is intersected with the first direction; the adapter is provided with a first adapter port and a second adapter port which are communicated; the first rotating interface is communicated with the connecting port of the to-be-detected piece, and the direction of the second rotating interface is the first direction. At the moment, the connecting plugging piece is spliced in the second adapter; therefore, the to-be-detected piece with the direction of the connecting port crossed with the first direction is fixed in the vacuum box by utilizing the matching of the adapter piece, the vacuum box and the connecting plugging piece, and the connecting port of the to-be-detected piece is sealed.

In some embodiments, at least one of the first housing and the second housing has a first seal groove; the air tightness detection sealing device further comprises a first sealing structure, and the first sealing structure is located in the first sealing groove. The first sealing structure seals the first housing and the second housing when the first housing and the second housing are combined into the vacuum box. Thus, the first sealing structure and the first sealing groove can form a sealing cavity, and meanwhile, the air leakage of the vacuum box can be prevented.

In some embodiments, the part to be inspected is in contact with at least one set of opposing inner walls of the vacuum box when the first and second housings are in a combined state. In this way, the member to be inspected can be restricted to at least one set of opposite inner walls (such as the opposite first inner wall and the opposite second inner wall hereinafter), and shaking of the member to be inspected between at least one set of opposite inner walls (such as the opposite first inner wall and the opposite second inner wall hereinafter) can be avoided, so that stability of the member to be inspected in the vacuum box is enhanced. In addition, the member to be inspected is in contact with at least one set of opposing inner walls (e.g., the opposing first inner wall and the opposing second inner wall hereinafter), so that the member to be inspected can be prevented from expanding between the at least one set of opposing inner walls (e.g., the opposing first inner wall and the opposing second inner wall hereinafter) to prevent the member to be inspected from expanding and deforming.

In some embodiments, the connection block includes a body portion and a second seal structure disposed on a side of the body portion. When the body part is inserted into the connecting port of the to-be-detected piece, the second sealing structure is sealed between the side face of the body part and the side face of the connecting port of the to-be-detected piece. Thus, the second sealing structure can prevent air leakage between the body part and the connecting port of the to-be-detected piece.

In some embodiments, the second sealing structure comprises a plurality of sealing rings; the plurality of the first guide members are arranged along the first direction and sleeved on the body part. In this way, the plurality of sealing rings are utilized to play a role in multiple sealing, so that the tightness between the body part and the connecting port of the to-be-detected piece is enhanced.

In some embodiments, the side of the body portion has a second seal groove, and the second seal structure portion is embedded within the second seal groove. And the other part of the second sealing structure is positioned outside the second sealing groove, so that when the connecting and plugging piece is plugged into the connecting port, the other part of the second sealing structure is extruded by the side surface of the connecting port, and the sealing and connecting plugging piece and the connecting port are arranged in the second sealing structure.

In some embodiments, the air tightness detection sealing device further comprises a base and a lifting mechanism, and the second housing is fixed on the base. The lifting mechanism is arranged on the base and is connected with the first shell; the lifting mechanism is configured to drive the first housing to move in a first direction. The vacuum box is connected with the lifting structure through the arranged base; when the lifting mechanism drives the first shell to move away from the second shell, the first shell and the second shell are detached and separated.

In some embodiments, the airtight detection sealing device further comprises a translation mechanism, wherein the translation mechanism is arranged on the base and is connected with the lifting mechanism; the translation mechanism is configured to drive the lifting mechanism to move on the base in a second direction. Under the condition that the first shell and the second shell are in a disassembly state, the translation mechanism can be used for enabling the first shell to be staggered with the second shell, so that a piece to be detected can be placed in the second shell conveniently.

In order to solve the technical problems, a second technical scheme provided by the application is as follows: the air tightness detection system comprises a gas detection device, a first vacuumizing device, a second vacuumizing device, an inflating device, a gas recovery device and the air tightness detection sealing device. The gas detection device is communicated with the vacuum box; the first vacuumizing device is communicated with the vacuum box; the second vacuumizing device is communicated with the inner cavity of the piece to be detected; the inflation device is communicated with the inner cavity of the piece to be detected; the gas recovery device is communicated with the inner cavity of the piece to be detected.

Due to the reduced volume of the vacuum box, the volume of the tightness detection sealing device is reduced, and thus the total volume of the tightness detection system is reduced. The volume of the vacuum chamber in the comparative version is greater than the volume of the vacuum box of the presently disclosed embodiments. When the part to be detected leaks, more gas leaks in the vacuum chamber in the comparison scheme, so that the detection range of the gas detection device can be reached; in the vacuum box of the embodiment of the disclosure, less leakage gas can reach the detection range of the gas detection device; therefore, the detection time of the to-be-detected piece is shortened, and the detection efficiency of the to-be-detected piece is improved.

The specific meaning of the above terms in the embodiments of the present application will be understood by those of ordinary skill in the art according to specific circumstances.

In the related art, the airtight detecting sealing device is used for fixing and sealing the to-be-detected member, and both the airtight detecting sealing device and the to-be-detected member located in the airtight detecting sealing device are connected with external equipment, so that the airtight of the to-be-detected member can be detected, so as to prevent the to-be-detected member from leaking medium (such as liquid, and gas) when in use. But current gas tightness detects sealing device can include vacuum chamber, stop gear, actuating mechanism and connection shutoff piece, and stop gear and actuating mechanism separately set up, and stop gear and actuating mechanism all are located the vacuum chamber. And fixing the part to be detected in the vacuum chamber by using a limiting mechanism. The connecting and blocking piece is arranged on the driving mechanism; the driving mechanism is used for driving the connecting plugging piece to move, so that a connecting port of the piece to be detected in the vacuum chamber is plugged. And finally, closing the vacuum chamber to be vacuumized. The limiting mechanism, the connecting plugging piece and the driving mechanism are all positioned in the vacuum chamber, so that the volume of the vacuum chamber is larger, and the total volume of the airtight detection sealing device is larger; when the pieces to be detected are detected, the detection time of each piece to be detected is longer, and the detection efficiency is lower.

In order to solve the problem that the total volume of the air tightness detection sealing device is large, embodiments of the present disclosure provide an air tightness detection sealing device. Referring to fig. 1 and 2, in the airtight detecting and sealing device 1, since the connection blocking member 16 is directly disposed on at least one of the first housing 111 and the second housing 112, and in the process of forming the vacuum box 11 with the combination of the first housing 111 and the second housing 112, the first housing 111 or the second housing 112 drives the connection blocking member 16 to block and seal the connection port 101 of the member to be detected 10, and the member to be detected 10 is fixed in the vacuum box 11. Therefore, the vacuum box 11 does not need to be provided with a driving mechanism in the related art to drive the connecting plugging member and the limiting mechanism, so that the volume of the vacuum box 11 pair can be reduced, and the total volume of the air tightness detection sealing device 1 can be reduced. Since the airtight detecting and sealing device 1 of the embodiment of the present disclosure seals the connection port of the member to be detected 10 with the connection stopper 16, the operation is simple (that is, there is no driving mechanism in the related art complicated in operation); then, when detecting the pieces to be detected 10, the detection time of each piece to be detected 10 can be shortened, thereby improving the detection efficiency.

In some embodiments, the part to be inspected 10 may be any container that needs to have a certain tightness, and the container may be a medium cooler, a medium reservoir, a medium heater, etc. The member to be detected 10 has an inner cavity and a connection port 101, and the connection port 101 communicates with the inner cavity so that a medium passes into and out of the inner cavity of the member to be detected 10 through the connection port 101.

The number of connection openings 101 may be one, for example, such that the medium passes through the connection openings 101 into the interior of the component 10 to be tested and out through the connection openings 101. Also by way of example, the number of connection ports 101 may be plural, for example, connection ports 101 may include an in-connection port and an out-connection port; i.e. the medium enters the inner cavity of the member to be detected 10 through the inlet connection port and exits from the outlet connection port. Wherein the medium may be at least one of a fixed, liquid and gas.

In some examples, the part to be inspected 10 also has other holes (i.e. detachable other holes) that can be opened. When the member to be detected 10 is used normally, other holes are in a closed state; for example, when the member to be detected 10 is abnormal, other holes can be opened to exclude the medium in the member to be detected 10; and for example, the medium in the element 10 to be inspected can be observed through other holes. That is, in normal use of the member to be detected 10, the inner cavity of the member to be detected 10 may be communicated with the outside through the connection port 101, and the other holes may make the inner cavity of the member to be detected 10 not communicated with the outside. For example, the other holes may be drain holes, inspection holes, spare holes, etc. The media cooler may be a water cooler, which may be a plate-like structure. The present application is described with respect to the case where the object to be inspected 10 may be a battery cooling plate.

Referring to fig. 1 to 6, an embodiment of the present disclosure provides a gas tightness detection sealing device 1, the gas tightness detection sealing device 1 including a connection block 16, and a first housing 111 and a second housing 112 detachably connected. The first housing 111 and the second housing 112 can be combined in a first direction Z into a vacuum box 11 with a sealed chamber 119. The connection blocking piece 16 is configured to block the connection port 101 of the part to be inspected 10 in the vacuum box 11. The connection block piece 16 is provided on at least one of the first housing 111 and the second housing 112; when the first housing 111 and the second housing 112 are combined into a vacuum box, the connection blocking member 16 is located in the vacuum box 11, and the connection blocking member 16 is connected to the connection port 101 of the member to be detected 10 in the vacuum box 11 and blocks the connection port 101 of the member to be detected 10 in the vacuum box 11. Referring to fig. 1 and 3, the first housing 111 and the second housing 112 are detachably connected; that is, the first housing 111 and the second housing 112 may be detachable or may be integrally formed. The first and second cases 111 and 112 can be combined into the vacuum box 11 having the sealed chamber 119 in the first direction Z, and a state in which the first and second cases 111 and 112 are combined into the vacuum box 11 may be referred to as a combined state. Accordingly, a state in which the first housing 111 and the second housing 112 can be detached may be referred to as a detached state. Namely, the first housing 111 and the second housing 112 have a separated state and a combined state; wherein, in the combined state, the first housing 111 and the second housing 112 may be referred to as a vacuum box 11 as a whole of the first housing 111 and the second housing 112. When the first casing 111 and the second casing 112 are combined into the vacuum box 11, the following description may be understood as a combined state; i.e. both expressions mean the same. In some examples, the inner surface polishing process and the cleaning process of the first housing 111 and the second housing 112 reduce the air accumulation of the first housing 111 and the second housing 112, and increase the extraction speed of the vacuum box 11.

For convenience of explanation, referring to fig. 1, the air-tightness detecting sealing device 1 of the embodiment of the present disclosure further has a second direction X and a third direction Y. The first direction Z intersects (e.g., is perpendicular to) the second direction X and intersects (e.g., is perpendicular to) the third direction Y; the second direction X intersects (e.g., is perpendicular to) the third direction Y. Perpendicular to the second direction X in the first direction Z and perpendicular to the third direction Y; in the case where the second direction X is perpendicular to the third direction Y, the first direction Z, the second direction X, and the third direction Y may constitute a three-dimensional coordinate system, and the first direction Z, the second direction X, and the third direction Y may constitute a three-dimensional coordinate system.

The connection block piece 16 is provided on at least one of the first housing 111 and the second housing 112; for example, the connection plug 16 is arranged on the first housing 111. Also for example, the connection block 16 is arranged on the second housing 112. For example, the connection plug 16 is provided on the first housing 111 and the second housing 112; the number of the connecting plugging pieces can be one or two; in the case where the number of the connection plugs is two, one connection plug is provided on the first housing 111, and the other connection plug 16 is provided on the second housing 112.

When the first housing 111 and the second housing 112 are combined into the vacuum box 11, the connection blocking member 16 is located in the vacuum box 11, and the connection blocking member 16 is connected to the connection port 101 of the member to be detected 10 in the vacuum box 11 and blocks the connection port 101 of the member to be detected 10 in the vacuum box 11.

In this way, in the process of combining the first housing 111 and the second housing 112 into the vacuum box 11, the first housing 111 or the second housing 112 may drive the connection plugging member 16 to plug the connection port 101 of the to-be-detected member 10, and fix the to-be-detected member 10 in the vacuum box 11. Therefore, the vacuum box 11 does not need to be provided with a driving mechanism in the related art to drive the connecting block piece 16 and the limiting mechanism, so that the volume of the pair of vacuum boxes 11 can be reduced, and the total volume of the airtight detecting and sealing device 1 can be reduced. Since the airtight detecting and sealing device 1 of the embodiment of the present disclosure seals the connection port of the member to be detected 10 with the connection stopper 16, the operation is simple (that is, there is no driving mechanism in the related art complicated in operation); then, when detecting the pieces to be detected 10, the detection time of each piece to be detected 10 can be shortened, thereby improving the detection efficiency.

The connecting blocking member 16 may be understood as a structure capable of blocking the connection port 101 of the member to be inspected 10 in the vacuum box 11 to isolate the inner cavity of the member to be inspected 10 from the sealing chamber 119 of the vacuum box 11 so that the inner cavity of the member to be inspected 10 is not communicated with the sealing chamber 119 of the vacuum box 11. In this way, the vacuum box 11 does not need to be provided with a driving mechanism in the related art to drive the connection plugs 16, so that the volume of the vacuum box 11 pair can be reduced.

In some embodiments, for example, the shape of the connection port 101 is circular, the cross-section of the connection block 16 is circular, and for example, the shape of the connection port 101 is polygonal, and the cross-section of the connection block 16 is polygonal. The connecting closure 16 may be a rod-shaped structure, for example a rod with a circular cross-section, or a rod with a polygonal cross-section. Wherein the cross section intersects (e.g., is perpendicular to) the direction of extension of the connection block 16. Specifically, the extending direction of the connection block piece 16 may be a first direction Z, and the connection block piece 16 is cylindrical in shape; in this way, the connection plug 16 can be moved synchronously with the first housing 111 or the second housing 112 in the first direction Z and inserted into the connection port 101.

The connection plug 16 is also capable of applying a certain pressure to the part to be tested 10. For example, the connection plug 16 is interference fit with the connection port 101 of the member to be detected 10; for another example, the outer side surface of the connection blocking piece 16 has a convex portion that can apply pressure to the port side wall of the connection port 101 of the member to be detected 10; the connecting plug 16 thus seals the connection opening 101 of the part to be tested 10, while limiting the part to be tested 10 in the first direction Z. In this way, by utilizing the cooperation of the connecting plugging piece 16 and the vacuum box 11, a limiting mechanism is not required to be arranged, so that the piece 10 to be detected is fixed in the vacuum box 11; nor is a drive mechanism required so that the connection port of the member to be inspected 10 is sealed.

The embodiment of the disclosure provides a contrast scheme, and the airtight detection sealing device of this contrast scheme can include carrier, vacuum housing, connection shutoff piece, stop gear and actuating mechanism, and the vacuum housing seals the setting and constitutes the vacuum chamber on the carrier. The limiting mechanism and the driving mechanism are separately arranged (namely, are not in an integral structure), and both the limiting mechanism and the driving mechanism are positioned in the vacuum chamber. The body of the piece to be detected is fixed on the carrier through the limiting mechanism (namely, the limiting mechanism is connected with a non-connecting port of the piece to be detected); the limiting mechanism can be a bolt, an elastic fixing piece, a buckle and the like. The driving mechanism is fixed on the carrier, and the connecting port of the part to be detected is sealed by the connecting plugging part through the driving mechanism; the driving mechanism may be a hydraulic driving mechanism, an air pressure driving mechanism, or the like. In this way, the driving mechanism (such as an air pressure driving mechanism) and the limiting mechanism in the comparison scheme are large in size and are arranged separately, so that the space occupied by the driving mechanism and the limiting mechanism in the vacuum chamber is large; in addition, the vacuum chamber is internally provided with a plurality of structures (namely a piece to be detected, a driving mechanism, a limiting mechanism and a connecting blocking piece), so that the volume of the vacuum chamber is larger.

In the comparison scheme, a plurality of structures (namely a piece to be detected, a driving mechanism, a limiting mechanism and a connecting blocking piece) exist; compared to the comparison scheme, the airtight detection sealing device 1 of the embodiment of the present disclosure adopts a structure (i.e. the connection plugging piece 16), and in the case that the airtight detection sealing device 1 can achieve the original function (by using the cooperation of the connection plugging piece 16 and the vacuum box 11, the to-be-detected piece 10 is fixed and sealed in the vacuum box 11), the structure of the airtight detection sealing device 1 is simplified (i.e. the driving mechanism and the limiting mechanism are removed), so that the volume of the vacuum box is reduced, and the volume of the airtight detection sealing device 1 is reduced.

In some embodiments, the connection block 16 is fixedly connected with at least one of the first housing 111 and the second housing 112, and the connection block 16 is detachably connected with the connection port 101 of the member to be detected 10.

In some embodiments, the connection block 16 is detachably connected with at least one of the first housing 111 and the second housing 112; for example, the connection block 16 is detachably connected to the first housing 111; also for example, the connecting closure 16 is detachably connected to the second housing 112; also for example, the connecting block 16 is detachably connected to the first housing 111 and the second housing 112.

The manner of detachably connecting the blocking member 16 to at least one of the first housing 111 and the second housing 112 is not limited; for example, the connecting block piece 16 is detachably connected with at least one of the first housing 111 and the second housing 112 by plugging; for another example, the connecting block piece 16 is detachably connected to at least one of the first housing 111 and the second housing 112 by magnetic attraction. As such, when the first housing 111 and the second housing 112 are combined into the vacuum box 11, there are at least two operation modes according to the operability of the workpiece 10 and the vacuum box 11, and two operation modes will be described below as examples.

Operation mode one: the connecting plugging member 16 can be connected with the connecting port 101 of the member to be detected 10 and plug the connecting port 101 of the member to be detected 10; then the whole connecting the blocking member 16 and the member to be inspected 10 is placed in the second housing 112 (or the first housing 111); after the first housing 111 (or the second housing 112) and the second housing 112 (or the first housing 111) in which the connection stopper 16 and the whole of the member to be inspected 10 are placed are combined into the vacuum box 11, the vacuum box 11 is connected to the first housing 111 and/or the second housing 112. From the fixing of the part to be inspected 10 in the vacuum box 11.

And the second operation mode is as follows: the connecting block piece 16 can be connected with the first housing 111 and/or the second housing 112 first, and then the piece 10 to be detected is placed in the second housing 112; when the first shell 111 and the second shell 112 form the vacuum box 11, the connecting and plugging piece 16 and the first shell 111 move synchronously, so that the connecting and plugging piece 16 is plugged into the connecting port 101 of the to-be-detected piece 10 to seal the connecting port 101 of the to-be-detected piece 10, and meanwhile, the to-be-detected piece 10 is fixed in the vacuum box 11.

In some embodiments, at least one of the first housing 111 and the second housing 112 is plugged with the connection block 16, the connection block 16 being plugged in the mounting slot 116. For example, the first housing 111 has a mounting groove 116, and the connection plug 16 is plugged into the mounting groove 116 of the first housing 111. For example, the second housing 112 has a mounting groove 116, and the connection plug 16 is plugged into the mounting groove 116 of the second housing 112. For example, the first housing 111 and the second housing 112 each have a mounting groove 116, and one connecting plug 16 is inserted into the mounting groove 116 of the first housing 111, and the other connecting plug 16 is inserted into the mounting groove 116 of the second housing 112. In this way, the attachment of the blocking member 16 to the first housing 111 and/or the second housing 112 is facilitated. In other examples, at least one of the first housing 111 and the second housing 112 is snapped into engagement with the connection block 16.

In some embodiments, the connection block 16 has an external connection channel 165, the external connection channel 165 communicating with the lumen of the member to be tested 10. In this way, the external connection 165 with the connection plug 16 can be connected to external devices outside the vacuum box 11.

In some examples, other apertures (e.g., drainage apertures) of the part to be inspected 10 may be opened such that the other apertures of the part to be inspected 10 communicate with external devices outside the vacuum box 11.

In some examples, the first housing 111 and/or the second housing 112 (e.g., the second housing 112) has a first channel 117, and an external device outside the vacuum box 11 communicates with the interior cavity of the part 10 to be inspected within the vacuum box 11 through the first channel 117. Wherein the first passage 117 is in a sealed state such that the sealed chamber 119 of the vacuum box 11 is in communication with the outside. In other examples, the first housing 111 and/or the second housing 112 has a first channel 117, and an external device outside the vacuum box 11 communicates with both the sealed chamber 119 of the vacuum box 11 and the interior cavity of the part 10 to be inspected through the first channel 117.

In some embodiments, the number of connection ports 101 of the member to be tested 10 is the same as the number of connection plugs 16. For example, in the case where the number of connection ports 101 of the member to be detected 10 is one, the number of connection plugs 16 may be one. For example, in the case where the number of connection ports 101 of the member to be inspected 10 is plural (for example, two or three), the number of connection plugs 16 may be plural (for example, two or three).

In some embodiments, referring to fig. 4-6, the connection block 16 may include a first connection block 161 and a second connection block 162. The first connection block 161 is connected to the first housing 111, and the second connection block 162 is connected to the second housing 112. The first connection blocking piece 161 and the second connection blocking piece 162 are disposed opposite to each other, and respectively block the two connection ports 101 of the member to be detected 10 disposed opposite to each other.

Each connection port 101 (e.g., an inlet connection port, and also e.g., an outlet connection port) of the member to be inspected 10 may include at least one connection port. For example, each connection port (e.g., an in-connection port, and also e.g., an out-connection port) of the member to be inspected 10 may include two connection ports 101 (the two connection ports 101 may be referred to as a first connection port 1011 and a second connection port 1012). The first connection blocking member 161 and the second connection blocking member 162 block two connection ports 101 (i.e., in the first connection port 1011 and the second connection port 1012) of the member to be inspected 10, respectively, which are disposed opposite to each other. Thus, one end of the first connection plug 161 is inserted into the first connection port 1011 of the member to be detected 10, and the other end is connected to the first housing 111 (for example, the other end is inserted into the mounting groove 116 of the first housing 111); one end of the second connection plugging member 162 is plugged into the second connection port 1012 of the member to be detected 10, and the other end is connected with the second housing 112 (for example, the other end is plugged into the mounting groove 116 of the second housing 112); thereby fixing the member to be inspected 10 between the other end of the first connection block member 161 and the other end of the second connection block member 162.

The first connection blocking piece 161 and the second connection blocking piece 162 are disposed opposite to each other, and it is understood that the extending direction of the first connection blocking piece 161 is the same as the extending direction of the second connection blocking piece 162. For example, the extending direction of the first connection plug 161 and the extending direction of the second connection plug 162 are both the first direction Z. Specifically, the first connection block piece 161 and the second connection block piece 162 are coaxially disposed.

In some embodiments, the connection block 16 moves in the first direction Z in synchronization with the first housing 111 (or the second housing 112). In this way, the connecting block piece 16 is connected to the first housing 111 (or the second housing 112), and the member to be inspected 10 is placed in the second housing 112 (or the first housing 111); the connection plugging member 16 moves along the first direction Z in synchronization with the first housing 111 (or the second housing 112), so that the connection plugging member 16 is inserted into the connection port 101 of the member to be detected 10 and connected with the first housing 111 and/or the second housing 112 in the process of forming the vacuum box 11 by the first housing 111 and the second housing 112.

In some embodiments, the direction of extension of the connection block 16 is a first direction Z; for example, the extending direction of the first connection plug 161 and the extending direction of the second connection plug 162 are both the first direction Z. After the member to be inspected 10 is placed (or put) in the vacuum box 11, the connection stopper 16 is brought into contact with the connection port 101 of the member to be inspected 10 in the case where the direction of the connection port 101 of the member to be inspected 10 is the first direction Z.

In some embodiments, the direction of extension of the connection block 16 is a first direction Z; in the case where the direction of the connection port 101 of the part to be inspected 10 intersects (e.g., is perpendicular to) the first direction Z after the part to be inspected 10 is placed (or put) in the vacuum box 11, the air-tightness detecting sealing device 1 further includes an adapter. The adapter is provided with a first adapter port and a second adapter port which are communicated; the first rotating interface is communicated with the connecting port 101 of the member to be detected 10 (for example, the first rotating interface and the connecting port 101 of the member to be detected 10 can be connected by screw threads or the like); the direction of the second interface is the first direction Z. At this time, the connecting plug 16 is plugged into the second adapter; so that the member to be inspected 10 whose direction of the connection port 101 crosses the first direction Z is fixed in the vacuum box 11 by the cooperation of the adapter, the vacuum box 11 and the connection stopper 16, and the connection port 101 of the member to be inspected 10 is sealed.

Where, for example, each connection port 101 of the member to be inspected 10 may include a first connection port 1011 and a second connection port 1012, the number of first connection ports per adapter is two. The extending direction of the connecting plugging member 16 is a first direction Z; for example, the extending direction of the first connection plug 161 and the extending direction of the second connection plug 162 are both the first direction Z.

The direction of the connection port 101 of the test piece 10 can be understood as the extending direction of the geometric center line of the connection port 101 of the test piece 10. When the connection port 101 of the workpiece 10 is, for example, circular, the direction of the connection port 101 of the workpiece 10 can be understood as the extending direction of the geometric center line of the connection port 101 of the workpiece 10 (since the axis coincides with the geometric center line when circular, the extending direction of the geometric center line can also be expressed as the extending direction of the axis). For example, the direction of the connection port 101 of the to-be-detected member 10 is the first direction Z, which may be understood as the extending direction of the geometric center line of the connection port 101 of the to-be-detected member 10. As another example, the direction of the connection port 101 of the member to be inspected 10 crosses the first direction Z hereinabove, and it can be understood that the extending direction of the geometric center line of the connection port 101 of the member to be inspected 10 crosses the first direction Z.

The direction of the first swivel joint is understood as the direction of extension of the geometric centre line of the first swivel joint. The direction of the second swivel joint can be understood as the direction of extension of the geometric centre line of the second swivel joint. The description of the direction of the first swivel interface and the direction of the second swivel interface may refer to the description of the direction of the connection port 101 of the object to be inspected 10.

In some embodiments, the direction of extension of the connection block 16 intersects (e.g., is perpendicular to) the first direction Z. For example, when the extending direction of the connection stopper 16 is the same as the direction of the connection port 101 of the member to be detected 10, the connection stopper 16 is in contact with the connection port 101 of the member to be detected 10. For another example, when the extending direction of the connection stopper 16 intersects (e.g., is perpendicular to) the direction of the connection port 101 of the member to be detected 10, the connection stopper 16 is connected to the connection port 101 of the member to be detected 10 via an adapter.

In some embodiments, at least one of the first housing 111 and the second housing 112 has a first seal groove 114. The tightness detecting and sealing device 1 further comprises a first sealing structure 113, wherein the first sealing structure 113 is located in the first sealing groove 114. The first sealing structure 113 seals the first housing 111 and the second housing 112 when the first housing 111 and the second housing 112 are combined into the vacuum box 11. Thus, the first seal structure 113 and the first seal groove 114 can form a seal chamber, and can prevent the vacuum box 11 from leaking.

For example, the first housing 111 has a first seal groove 114; the second housing 112 and the first seal groove 114 of the first housing 111 enclose the seal chamber 119. For another example, the second housing 112 has a first seal groove 114; the first seal groove 114 of the first housing 111 and the second housing 112 encloses the seal chamber 119. For another example, the first housing 111 and the second housing 112 each have a first seal groove 114; at this time, the first seal groove 114 of the second housing 112 and the first seal groove 114 of the first housing 111 enclose the seal chamber 119 described above.

Illustratively, the first seal structure 113 is adapted to the structure of the first seal groove 114. For example, in the case of the first seal groove 114 being annular; the first sealing structure 113 is annular, and in this case, the first sealing structure 113 may be referred to as a sealing ring. The material of the first sealing structure 113 may be silica gel or rubber.

In some embodiments, the part to be inspected 10 is in contact with at least one set of opposing inner walls of the vacuum box 11 when the first housing 111 and the second housing 112 are in a combined state. In this way, the part to be inspected 10 can be restricted to at least one set of opposite inner walls (e.g. the opposite first inner wall and the opposite second inner wall hereinafter), and the part to be inspected 10 can be prevented from shaking between at least one set of opposite inner walls (e.g. the opposite first inner wall and the opposite second inner wall hereinafter), and the stability of the part to be inspected 10 in the vacuum box 11 is enhanced. In addition, the member to be inspected 10 is in contact with at least one set of opposing inner walls (e.g., opposing first inner wall and second inner wall hereinafter), so that the member to be inspected 10 can be prevented from expanding between the at least one set of opposing inner walls (e.g., opposing first inner wall and second inner wall hereinafter) to prevent the member to be inspected 10 from expanding and deforming.

Illustratively, the sealing chamber 119 of the vacuum box 11 is contoured to the part 10 to be inspected, preventing deformation of the shape of the part 10 to be inspected. The contoured design of the sealed chamber 119 of the vacuum box 11 with the part 10 to be inspected can be understood to mean that the shape of the sealed chamber 119 of the vacuum box 11 is substantially the same as the shape of the part 10 to be inspected. Moreover, the volume of the sealing chamber 119 is slightly larger than the volume of the member to be inspected 10, or the inner wall surface of the sealing chamber 119 is partially or entirely bonded to the outer wall surface of the member to be inspected 10. For the to-be-detected member 10 with a very thin cavity wall, during the internal inflation detection process, the cavity wall of the to-be-detected member 10 may be extruded and deformed or even be broken by the internal air pressure, so that the sealing cavity 119 of the vacuum box 11 and the to-be-detected member 10 are in a profile design, and the shape deformation of the to-be-detected member 10 can be prevented. Since some gaps exist between part or all of the inner wall surface of the sealed chamber 119 and the outer wall surface of the member to be inspected 10, the leaked inspection gas can be contained and drained. In some examples, micro-grooves may also be provided in the inner wall of the sealed chamber 119 to contain and drain the leaking test gas.

In some embodiments, since part or all of the inner wall surface of the sealing chamber 119 is attached to the outer wall surface of the to-be-detected member 10, the internal gap has poor drainage effect on the leaked detection gas, and a plurality of detection ports may be formed on the inner wall surface of the vacuum box 11, and a sensor for detecting the gas is disposed in each detection port. For example, the first housing 111 and the second housing 112 each have a receiving groove, and a plurality of detecting openings are formed in a groove wall of the receiving groove of the second housing 112, and the plurality of detecting openings are circumferentially spaced around the second housing 112. Wherein both the receiving groove of the first housing 111 and the receiving groove of the second housing 112 may be mated to form a sealing chamber 119; the receiving groove of the first housing 111, the receiving groove of the second housing 112, and the second sealing groove may cooperate to form a sealing chamber 119.

For example, the vacuum box 11 has a set of opposing inner walls (which may be referred to as opposing first and second inner walls) that may be arranged in a first direction Z, a second direction X, or a third direction Y.

For another example, vacuum box 11 has three sets of opposing inner walls (the two sets of opposing inner walls may be referred to as a first inner wall, a second inner wall, a third inner wall, and a fourth inner wall), the first inner wall opposing the second inner wall, the third inner wall opposing the fourth inner wall; the first and second inner walls may be arranged in one of the first, second and third directions Z, X and Y, and the third and fourth inner walls may be arranged in the second direction X.

For another example, the vacuum box 11 has three sets of opposing inner walls (the three sets of opposing inner walls may be referred to as a first inner wall, a second inner wall, a third inner wall, a fourth inner wall, a fifth inner wall, and a sixth inner wall), the first inner wall opposing the second inner wall, the third inner wall opposing the fourth inner wall, and the fifth inner wall opposing the sixth inner wall; the first and second inner walls may be arranged in one of the first, second and third directions Z, X, Y, the third and fourth inner walls may be arranged in the second direction X, and the fifth and sixth inner walls may be arranged in the third direction Y.

In some embodiments, the cross section of the connecting closure member 16 is adapted to the shape of the connection port 101 of the member to be tested 10, and the outer side surface of the connecting closure member 16 is in contact with the inner side surface of the connection port 101 of the member to be tested 10; so that the connection plug 16 directly plugs the connection port 101 of the member to be inspected 10.

In some embodiments, with continued reference to fig. 4-6, the connection block 16 includes a body portion 163 and a second sealing structure 164, the second sealing structure 164 being disposed on a side of the body portion 163. When the body 163 is inserted into the connection port 101 of the workpiece 10, the second sealing structure 164 is sealed between the side surface of the body 163 and the side surface of the connection port 101 of the workpiece 10. Thus, the second sealing structure 164 is provided to prevent air leakage between the body 163 and the connection port 101 of the workpiece 10. For example, the body 163 extends in the first direction Z. The body portion 163 may be cylindrical, such as a cylinder. The material of the body 163 may be plastic, and the material of the second sealing structure 164 may be silica gel or rubber.

In some embodiments, the second sealing structure 164 may include a sealing ring.

In some embodiments, the second sealing structure 164 may include a plurality (e.g., two, and yet another example, three) of sealing rings. The plurality of sealing rings are arranged along the first direction Z (for example, a gap exists between two adjacent sealing rings, and for example, two adjacent sealing rings are contacted with each other), and the plurality of sealing rings are sleeved on the body part 163. In this way, the plurality of seal rings function as multiple seals, thereby enhancing the sealing property between the body 163 and the connection port 101 of the workpiece 10 to be inspected.

In some embodiments, the side of the body 163 has a second seal groove 166, and a portion of the second seal structure 164 is embedded within the second seal groove 166. The other part of the second sealing structure 164 is located outside the second sealing groove 166, so that when the connecting plug 16 is plugged into the connecting port 101, the other part of the second sealing structure 164 is pressed by the side surface of the connecting port 101, so that the connecting plug 16 and the connecting port 101 are sealed in the second sealing structure 164. I.e., the second sealing structure 164 is an interference fit with the connection port 101.

In one possible implementation, where the second sealing structure 164 includes a plurality of sealing rings; for example, the number of the second sealing grooves 166 may be one, and a plurality of sealing rings are sleeved in the second sealing grooves 166. For another example, the number of the second seal grooves 166 may be plural, and when the number of the second seal grooves is the same as that of the plural seal rings, the plural seal rings are respectively sleeved in the plural second seal grooves 166; the plurality of second seal grooves 166 are arranged along the first direction Z.

In one possible implementation, the direction of extension of the connection plug 16 is the first direction Z, and the direction of the connection port 101 (or the first connection port 1011 and the second connection port 1012) is the first direction Z. One end of the body 163 of the first connecting plug 161 is inserted into the first connecting port 1011, and the other end is inserted into the mounting groove 116 of the first housing 111; one end of the body 163 of the second connecting plug 162 is inserted into the second connecting port 1012, and the other end is inserted into the mounting groove 116 of the second housing 112; the first sealing structure 113 of the first connection block piece 161 is used for sealing the body portion 163 of the first connection block piece 161 and the first connection port 1011, and the first sealing structure 113 of the second connection block piece 162 is used for sealing the body portion 163 of the second connection block piece 162 and the second connection port 1012. For example, the first connection block 161 has an external connection channel 165, and for example, the second connection block 162 has an external connection channel 165; for another example, the first connection block 161 and the second connection block 162 each have an external connection channel 165 that communicates with and can communicate with two structures in an external device.

In some embodiments, with continued reference to fig. 1 and 2, the tightness detection sealing device 1 further comprises a base 13 and a lifting mechanism 15. The second housing 112 is fixed to the base 13. The elevating mechanism 15 is mounted on the base 13, and the elevating mechanism 15 is connected to the first housing 111. The lifting mechanism 15 is configured to move the first housing 111 in the first direction Z. The first direction Z may be perpendicular to the plane of the base 13, for example, when the first direction Z is a vertical direction, the lifting mechanism 15 is configured to drive the first housing 111 to rise or fall.

When the lifting mechanism 15 drives the first housing 111 to move towards the second housing 112, the first housing 111 and the second housing 112 form the vacuum box 11. When the lifting mechanism 15 drives the first shell 111 to move away from the second shell 112, the first shell 111 and the second shell 112 are detached and separated.

The lifting mechanism 15 may be a telescopic mechanism having a telescopic function, and for example, the telescopic mechanism may be an electric telescopic mechanism, a hydraulic telescopic mechanism, an air-pressure telescopic mechanism, a screw lifting mechanism 15, or the like. In some examples, the lifting mechanism 15 may be an air cylinder.

In some embodiments, with continued reference to fig. 1 and 2, the tightness detection sealing device 1 further comprises a translation mechanism 17. The translation mechanism 17 is disposed on the base 13, and the translation mechanism 17 is connected with the lifting mechanism 15. The translation mechanism 17 is configured to drive the lifting mechanism 15 to move on the base 13 in the second direction X. For example, when the second direction X is a horizontal direction, the translation mechanism 17 is configured to drive the lifting mechanism 15 to translate on the base 13. With the first housing 111 and the second housing 112 in the disassembled state, the first housing 111 and the second housing 112 can be staggered by the translation mechanism 17, so that the to-be-detected piece 10 can be placed in the second housing 112 conveniently.

In some examples, translation mechanism 17 may have a telescoping mechanism with telescoping functionality; the type of telescopic mechanism may be referred to in the lifting mechanism 15 as described in relation to the type of telescopic mechanism. In some examples, the translation mechanism 17 may be a cylinder.

In some examples, the tightness detection sealing device 1 further comprises a frame 14, the lifting mechanism 15 being mounted on the frame 14, the frame 14 being mounted on the translation mechanism 17.

In some examples, the number of lifting mechanisms 15 may be one or more. The plurality of lifting mechanisms 15 may be arranged along the third direction Y, and the plurality of lifting mechanisms 15 are connected to one translation mechanism 17, so that one translation mechanism 17 may drive the plurality of lifting mechanisms 15 to move synchronously.

In some examples, the air-tightness detecting and sealing device 1 further includes a sliding mechanism by which the frame 14 is provided on the base 13; the translation mechanism 17 is connected to the frame 14. The sliding mechanism may be a structure of a slider and a slide rail. In some examples, the gantry 14 rests on the base 13 and the translation mechanism 17 is coupled to the gantry 14.

In some embodiments, the airtight detecting and sealing device 1 further includes a code scanner 12, where the code scanner 12 is disposed on the base 13, for recording the to-be-detected member 10. For example, the piece to be detected 10 is attached with a bar code, and the bar code scanner 12 is used for scanning the bar code to indicate that the piece to be detected 10 is detected.

In some embodiments, the first housing 111 is provided with a positioning member 115, the second housing 112 has a positioning hole 118, and the positioning member 115 can be inserted into the positioning hole 118; the positioning member 115 and the positioning hole 118 are provided to facilitate connection of the first housing 111 and the second housing 112.

Embodiments of the present disclosure provide a further air-tightness detection system, referring to fig. 7, configured to detect air tightness of the part to be detected 10 to prevent the part to be detected 10 from being used by leakage (e.g., air leakage, liquid leakage), thereby avoiding occurrence of safety accidents. The leaked part to be inspected 10 may also be referred to as a defective part to be inspected 10.

The air tightness detection system includes an air tightness detection sealing device 1 and an external device. Wherein the external equipment may include a first evacuating device 6, a second evacuating device 2, an inflating device 3, a gas recovery device 4, and a gas detection device 5. The gas detection device 5 and the first vacuumizing device 6 are communicated with a vacuum box 11; the second vacuumizing device 2, the inflating device 3 and the gas recovery device 4 are all communicated with the inner cavity of the member to be detected 10, for example, the second vacuumizing device 2, the inflating device 3 and the gas recovery device 4 can be communicated with the inner cavity of the member to be detected 10 through the same external connecting channel 165. So that the air tightness of the object to be inspected 10 can be inspected using the air tightness inspection sealing device 1 and the external equipment.

The working principle of the air tightness detection system is as follows: the first housing 111 and the second housing 112 are formed into the vacuum box 11 by, for example, a robot. And the air tightness detecting and sealing device 1 is connected with external equipment (i.e., the member to be detected 10 is fixed and sealed in the vacuum box 11, and the external equipment is communicated with the vacuum box 11 and the member to be detected 10). Starting the first vacuumizing device 6 to vacuumize the vacuum box 11 and reaching a preset vacuum degree; starting the second vacuumizing device 2 to vacuumize the to-be-detected piece 10 and reaching a preset vacuum degree; the first evacuating means 6 and the second evacuating means 2 are closed. Starting the gas detection device 5 to detect the gas in the vacuum box 11; starting the inflating device 3 to inflate preset gas in the member to be detected 10, and then closing the inflating device 3; if the gas detection device 5 detects gas in the vacuum box 11 (for example, the gas detection device 5 alarms to indicate that the gas is detected), the member to be detected 10 leaks; if the gas detection device 5 does not detect the gas in the vacuum box 11, the member to be detected 10 does not leak; the gas detection means 5 are turned off. Starting the gas recovery device 4 to recover the gas in the member to be detected 10 for the next use; after the recovery is finished. The vacuum degree of the vacuum box 11 and the piece 10 to be detected is broken, the vacuum box 11 is opened, the piece 10 to be detected is taken out by a manipulator, and the detection of the piece 10 to be detected is completed once. If the to-be-detected piece 10 leaks gas, the to-be-detected piece is placed on a defective goods shelf; if the to-be-detected piece 10 does not leak gas, the to-be-detected piece is placed on a good product shelf.

As the volume of the vacuum box 11 is reduced, the volume of the tightness detection sealing device 1 is reduced, so that the total volume of the tightness detection system is reduced. The volume of the vacuum chamber in the comparative version is greater than the volume of the vacuum box 11 of the presently disclosed embodiment. When the member to be detected 10 leaks, more gas leaks in the vacuum chamber in the comparison scheme, so that the detection range of the gas detection device 5 can be reached; in the vacuum box 11 of the embodiment of the disclosure, less leakage gas can reach the detection range of the gas detection device 5; thereby reducing the detection time of the member to be detected 10 and further improving the detection efficiency of the member to be detected 10.

In some embodiments, the first evacuating device 6 may include a first vacuum pump, a first vacuum measuring mechanism, and a first valve. The first vacuum pump communicates with the vacuum box 11 through a first valve for opening or shutting off the vacuum box 11 and the first vacuum pump. The first vacuum measuring means is for measuring the vacuum in the vacuum box 11, and may be a pirani vacuum measurement. The first valve may be a solenoid valve.

In some embodiments, the second evacuating device 2 may include a second vacuum pump, a second vacuum measuring mechanism, and a second valve.
