Description

Technical Field

[0001] The invention belongs to the field of pipeline sealing detection equipment, and more specifically relates to a male joint pipeline sealing detection machine. Background Art

[0002] The pipelines here refer to vehicle pipelines, including vacuum pipelines, fuel pipelines, brake pipelines, urea pipelines, cooling pipelines, spray pipelines, etc. The ends of the pipelines are generally connected with joints to facilitate the connection and quick installation of the pipelines. The joints are generally divided into female joints and male joints. Here we are talking about the sealing test of the pipelines equipped with male joints.

[0003] The female and male connectors on the pipeline can be docked. The male connector is generally designed as a hollow tube with a step, and the front end has a circular arc taper, which plays a guiding role during docking. The structure of the female connector is relatively complex. Generally, female connectors have two functions, namely sealing function and self-locking function. There are two O-rings inside the female connector. When the male connector is inserted into the female connector, the O-ring plays a sealing role. At the same time, there is a self-locking elastic buckle in the female connector that is stuck on the step of the male connector to lock the connection and realize the memory fixation of the male connector. This self-locking buckle in the female connector has an unlocking function. As long as you press and pinch the unlocking elastic buckle with your fingers, the elastic buckle can be evacuated from the step of the male connector, and the connection between the female and male connectors can be disconnected.

[0004] In addition, the pipeline needs to be tested for sealing according to the national standard or enterprise standard before leaving the factory, and 100% full inspection is adopted. At present, most of the management sealing detection equipment is manual detection, that is, multiple self-made male connectors are installed on a manifold, and there is an air hole on the manifold connected to the leak detector. A transition pipeline with press-fit female connectors at both ends is inserted into the male connector on the manifold. In this way, one end of the transition pipeline is inserted into the self-made male connector on the manifold, and the other end is connected to the male connector of the tested pipeline, and the sealing test can be detected.

[0005] After the sealing test is completed, each pipe is manually unplugged one by one. The disadvantages of this method are low efficiency and high labor intensity of manual unplugging. In theory, each connection point on the pipeline is a leak point. Because an extra transition pipeline is installed, the detection accuracy is also affected. The detection data is not automatically, timely and accurately recorded, and cannot be saved and traced. Summary of the invention

[0006] The purpose of the present invention is to provide a male joint pipeline sealing detection machine, which can perform sealing detection and loading and unloading at the same time, thereby improving the detection operation efficiency; the male joint to be tested is directly connected to the manifold, reducing the intermediate pipeline, reducing the leakage point, and improving the detection accuracy and efficiency; the male joint is automatically fixed during installation, and the exposed unloading of the male joint can be completed in one time, the unloading is convenient and quick, and the unloading labor intensity is low.

When one installation mechanism is performing detection, the other installation mechanism can perform loading and unloading operations.

[0009] Preferably, all the detection holes on the busbar are arranged in a straight line to form a detection hole group, and the male connector includes a sealing ring arranged at the outer end of the detection hole, a cover plate with holes that is pressed against the sealing ring and fixed to the busbar, and a guide rod symmetrically arranged on the upper and lower sides of the detection hole group, and the guide rod is sequentially sleeved with a number of card plates, springs and fixed baffles that are adapted to the detection holes, the fixed baffle is fixed to the busbar, and the card plate can slide along the guide rod, and the card plate realizes the compression of the step on the male connector inserted into the detection hole, thereby fixing the male connector;

[0010] The card plate is an L-shaped plate, one side of which is sleeved with the guide rod, and the other side is parallel to the mouth of the detection hole and has two C-shaped openings arranged opposite to each other. The two C-shaped openings are respectively placed outside the two adjacent detection holes, and the male connector passes through the C-shaped openings and is inserted into the detection hole; one of the C-shaped openings on the card plate is pressed against the step of the male connector under the elastic action of the spring, thereby fixing the male connector, and the other C-shaped opening plays a guiding role when the male connector is inserted.

[0011] Preferably, the detection machine comprises two mounting modules, each of which is provided with a male connector of one type;

[0012] Each of the two installation modules is connected to a selection mechanism, which drives the installation module connected thereto to move to a detection station or a waiting station;

[0013] The selection mechanism includes a fixed plate arranged at the rear of the installation module and a selection cylinder installed on the fixed plate. The cylinder push rod of the selection cylinder is fixedly connected to the two installation mechanisms at the same time. The selection cylinder pushes the installation module connected to it forward to the detection station or pushes the installation module connected to it backward to the waiting station to realize the selection of the two installation modules.

[0014] The detection machine is provided with a protective mechanism, which includes rodless cylinders fixed at both ends of the busbar and arranged vertically, and a shielding plate is connected between the two rodless cylinders. The shielding plate is placed on the outside of the installation module and is raised and lowered under the action of the rodless cylinder, thereby shielding and protecting the installation module at the waiting station.

[0015] Preferably, the unloading module includes two unloading mechanisms respectively connected to the two mounting mechanisms, and the unloading mechanisms can expose all the steps on all the male connectors installed on the mounting mechanisms connected thereto at one time, so as to facilitate the male connectors to be pulled out of the detection hole for unloading.

The fixing ring is placed on the side of the clamping plate away from the spring. The unloading cylinder pushes the guide rod, and the guide rod pushes the clamping plate to compress the spring through the fixing ring thereon, exposing the step on the male connector that is pressed by the C-shaped mouth, making it convenient for the male connector to be pulled out of the detection hole for unloading.

[0017] Preferably, the detection module includes an air source, a booster connected to the air source, and a leak detector; the air source is also connected to air valves corresponding to the number of installation mechanisms, each air valve is connected to an installation mechanism, and the air valve blows air into the pipeline after detection to clean the residue in the pipeline.

[0018] Preferably, the detection machine further comprises an industrial computer, a printing module and an air purification module, and the installation module, the unloading module, the detection module, the printing module and the air purification module are all controlled by the industrial computer;

[0032] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.

[0033] Because in the prior art, when performing sealing detection, the conventional operation is to first connect the female connectors one by one with the self-made male connectors for detection installation on the manifold, then connect a transition pipeline with female connectors at both ends at the rear of the female connector, and then connect the pipeline to be tested with a male connector at the other end of the transition pipeline, block the other end of the pipeline to be tested, and finally perform the test. After the test is completed, the male connectors of the pipeline to be tested are unplugged from the female connector of the transition pipeline one by one. The operation method has been introduced in the above background technology, that is, press and pinch the unlocking elastic buckle on the female connector with your fingers, remove the elastic buckle from the step of the male connector, and then unplug the connection between the female and male connectors. The above-mentioned operation method requires the pipelines of the male connectors to be tested to be loaded and unloaded one by one. The loading and unloading operation time is long, and the detection work cannot be performed during loading and unloading, which seriously affects the efficiency of the detection work; on the other hand, during unloading, manually press and pinch the unlocking elastic buckle on the female connector, which is labor-intensive and difficult to operate.

[0034] Based on the defects of the male connector in the prior art described in the previous paragraph, a detection machine is designed in the technical solution of the present invention to solve the above problems. The design principle and logic of the detection machine in this technical solution are as follows Figure 1 As shown. A detection operation position is set on the detection machine, and two installation modules (i.e., installation module [1]) and installation module [2], which are respectively installed with different types of male connectors (i.e., male connector [1] and male connector [2]) are set on the detection operation position. Then, according to the type of the male connector to be tested, the installation module is selected through two different selection mechanisms (i.e., selection mechanism [1] and selection mechanism [2]). The installation module with an adapted male connector is pushed forward to the detection station of the detection operation position, and the other installation module that cannot be adapted stays at a relatively backward position and is isolated by a protective mechanism to avoid collision.

[0035] In this way, one detection machine can perform seal detection on pipelines of at least two different types of male connectors, thereby improving the adaptability and utilization rate of the detection machine. Then, two installation mechanisms (i.e., installation mechanism [1-1] and installation mechanism [1-2]) for connecting male connectors that can perform independent detection are set on each installation module. The two installation mechanisms perform detection work in a cycle. When one of the installation mechanisms is performing detection, the other installation mechanism can perform loading (connecting the male connector to the male connector connector) and unloading (unplugging the tested male connector from the male connector connector) operations. In this way, the problem of spending a lot of time on loading and unloading and not being able to perform detection work during the loading and unloading time, which leads to low efficiency of seal detection, is effectively avoided in the prior art.

[0036] Each mounting mechanism (mounting mechanism [1-1], mounting mechanism [1-2], mounting mechanism [2-1], mounting mechanism [2-2]) on each of the two mounting modules is respectively connected to a discharge mechanism (respectively connected to a discharge mechanism [1-1], a discharge mechanism [1-2], a discharge mechanism [2-1], a discharge mechanism [2-2]) and a detection switch (detection switch [1-1], detection switch [1-2], detection switch [2-1], detection switch [2-2]), and each discharge structure and detection switch respectively performs detection control and discharge operation on the mounting mechanism connected thereto.

[0037] like Figure 2 As shown, it is an overall schematic diagram of a male joint pipe sealing detection machine of the technical solution of the present invention. Among them, the inspection door on the detection machine at the position marked 1 can be used to inspect the internal faults of the detection machine through the inspection door 1. The marking 2 is the operation button on the detection machine. This operation button 2 is connected to the industrial computer 4 and is used for the start, pause and emergency stop of the detection machine. The marking 3 is the operation button connected to the industrial computer. This operation button 3 is connected to the selection mechanism, detection module, unloading module, etc. to realize the control of the detection machine in the selection, detection and unloading work steps. The marking 6 is the protective cover of the detection operation position, that is, to protect the installation mechanism on the installation module of the detection operation position, and to isolate the installation mechanism from the surrounding equipment, so as to achieve semi-wrapping of the installation mechanism and protect the installation mechanism.

[0038] like Figure 3 As shown, it is a schematic diagram of the internal structure of the detection machine of the technical solution of the present invention, wherein the mark 7 is the air purifier of the air purification module, and the air purifier 7 is connected to a cigarette butt, which moves with the laser printing component to absorb the smoke generated by the printing part. The mark 8 is the supercharger, and the mark 9 is the laser generator of the laser printing component. The mark 11 is the leak detector of the detection module, and the detection principle and detection operation steps of the leak detector 11 are the existing technology. Here, the detection principle of the leak detector 11 for the pipeline to be inspected is consistent with the detection method and principle in the existing technology.

[0039] like Figure 4As shown, it is a schematic diagram of the structure of the laser printing assembly on the detection machine of the technical solution of the present invention. The detection machine is equipped with a tooling installation plate 14 parallel to the detection hole group, and a drag chain 15 is arranged on the tooling installation plate 14. The drag chain 15 is connected with the cigarette head of the air purifier 7, the printing mechanism and the driving mechanism of the laser printing assembly. The printing mechanism includes a servo three-dimensional slide 18 driven by a drag chain (which can realize the movement in six directions of front, back, left, right, up and down, mainly using a cylinder or a lead screw to complete the movement, which is a conventional device in the prior art), a support plate 17 is installed on the servo three-dimensional slide 18, a laser optical path 19 is installed on the support plate 17, and a laser printing head is connected to the laser optical path 19, and the laser printing head and the cigarette head move synchronously. The specific work is: after the detection is completed, the industrial computer determines that all male connectors are qualified, and then the industrial computer automatically controls the driving mechanism to drive the cigarette head of the air purifier 7 and the printing mechanism of the laser printing assembly to move to the upper part of the male connector, and the laser generator 9 and the laser optical path 19 work, so that the laser printing head prints the qualified male connector with the qualified mark. Meanwhile, when the laser print head is printing, the air purifier 7 is working, and the smoking head of the air purifier 7 sucks out the polluted smoke generated during printing, thereby cleaning the environment.

[0040] In the above technical solution, the laser printing component automatically prints the qualified male connector, which is conducive to the identification of the male connector, the extraction and storage of the male connector data, and the convenience of data management, construction management and after-sales traceability in the later stage. At the same time, the setting of the air purifier 7 can timely clean the waste gas generated by printing, purify the environment, improve the working environment of the staff, and ensure the physical safety of the staff.

[0041] like Figure 4 In the figure, marked 20 and 21 are respectively the rodless cylinder of the protective mechanism and the baffle plate connected to the two rodless cylinders. The baffle plate 21 is placed on the outside of the installation module. The rodless cylinder 20 drives the baffle plate 21 to move up and down, so as to shield the installation module that is not involved in the detection work at the waiting station, avoid it from external collision and pollution, and avoid the detection holes and male connectors on the installation module from being damaged, which affects the detection work.

[0042] like Figure 5 The detection machine of the technical solution includes an installation module for installing a male connector, and a discharge module and a detection module connected to the installation module. The male connector is installed on the installation module, and then the detection module is used to detect it. If the sealing of all the male connector pipelines involved in the detection is qualified, the qualified mark is marked on each male connector pipeline; if there is an unqualified seal, no mark is made.

[0043] like Figure 5The above is a schematic diagram of the structure of the selected mechanism and the position of the installation module of the detection machine. The detection machine is provided with two upper and lower installation modules A and B. Of course, the two installation modules A and B can also be arranged in a left-right arrangement, as long as one of the installation modules does not cause interference or interference when the other installation module is working. Different types of male connectors are installed on the two installation modules A and B, respectively, for adapting to different types of male connector pipeline detection. The design of this technical solution effectively increases the adaptability of the detection machine, and can detect more types of pipelines and male connectors, improve the utilization rate of the detection machine equipment, and reduce costs for enterprises.

[0044] Each mounting module in this technology includes two mounting mechanisms, such as Figure 5 The installation module A shown in the figure includes two installation mechanisms A1 and installation structure A2 respectively connected to the detection module. The installation mechanism A1 and the installation structure A2 are arranged to be arranged left and right, and of course, they can also be arranged to be arranged up and down. It is only necessary that when one of the installation mechanism A1 and the installation structure A2 is being detected, the other can load and unload without being affected or blocked. The two installation mechanisms A1 and A2 perform the detection work in a cycle, that is, when one of the installation mechanisms is being detected, the other installation mechanism can perform loading and unloading operations. The design of this technical solution effectively solves the problem of time waste in loading and unloading, and improves the efficiency of sealing detection work.

[0045] In this technology, each of the two installation modules A and B is connected to a selection mechanism, which can work independently. The selection mechanism drives the installation module connected to it to move to the detection position or the waiting position to realize the installation module selection. Figure 5 As shown, in order to describe the structure of the selected mechanism and its work, and to simplify the description language and facilitate understanding, the following is a comparison Figure 5 A specific embodiment of the selection mechanism on the installation module A is described. The selection mechanism includes a fixed plate 14 arranged at the rear of the installation module A and a selection cylinder 16 installed on the fixed plate 14. The cylinder push rod 28 of the selection cylinder 16 passes through the fixed plate 14 and is fixedly connected to the two installation mechanisms A1 and A2 at the same time. The selection cylinder 16 pushes the installation module A connected thereto forward to the detection station or pushes the installation module A connected thereto backward to the waiting station to realize the selection of the installation module. Figure 5 Four selection cylinders 16 can be seen in the figure, and the four selection cylinders are respectively connected to a mounting mechanism, and the two selection cylinders at the top are respectively fixedly connected to the two mounting mechanisms A1 and A2 on the mounting module A and work synchronously. The two selection cylinders at the bottom are fixedly connected to the two mounting mechanisms on the mounting module B and work synchronously.

[0046] like Figure 5As shown, in order to ensure that the installation module A moves stably and has a fixed motion trajectory during selection, a guide rod 23 passing through the fixed plate 14 is connected to the manifold 22 on the installation module A, and a linear bearing 24 fixed to the fixed plate is sleeved on the guide rod 23 to reduce the friction of the guide rod 23. The installation module B is configured in this way to ensure its stable movement.

[0047] like Figure 5 As shown, the two installation mechanisms A1 and A2 in the present technology each include a manifold, and the two manifolds are respectively provided with a plurality of detection holes and an air inlet channel connecting all the detection holes and the detection module on the manifold; a male connector is provided outside the detection hole. A separate detection switch is provided on each of the two air inlet channels. A verification hole is also provided on each of the two manifolds, and the verification hole is connected to one of the detection holes on the manifold.

[0048] In order to facilitate the description of the structure and to simplify the description process and description language, the following is a specific description of the embodiment of the installation mechanism A2 on the installation module A. The structure and working principle steps of the installation mechanism A1 are the same as those of the installation mechanism A2, and the structure and working principle steps of the installation module B are the same as those of the installation module A.

[0049] like Figure 7 As shown, the two installation mechanisms A2 in this figure each include a manifold 22, on which a plurality of detection holes 30 and an air inlet channel connecting all the detection holes and the detection module on the manifold 22 are arranged. A male connector is arranged outside the detection hole. A separate detection switch is connected to the air inlet channel. The air source of the detection module is connected to the air inlet channel, and the detection work on the installation mechanism A2 is automatically controlled by an industrial computer through the detection switch. When loading, connect the male connector of the pipeline to be tested with the male connector, so that the pipeline to be tested is connected to the detection hole, the other end of the pipeline to be tested is blocked, and the detection begins.

[0050] The manifold 22 is also provided with a verification hole, which is connected to one of the detection holes on the manifold 22, and the general verification hole is connected to the first detection hole. The verification hole is blocked when not in use. When a male connector with unqualified sealing appears on the manifold 22, all male connectors are unplugged, and then the remaining detection holes except the first detection hole are blocked, and the male connectors that have just been detected as unqualified are connected to the first detection hole one by one, and the air source is connected to the verification hole to form a detection loop of the verification hole and the first detection hole, so as to check all male connectors that have just been detected as unqualified and find out the unqualified products.

[0051] like Figure 7, all the detection holes 30 on the busbar 22 are arranged in a straight line to form a detection hole group. The male connector includes a sealing ring arranged at the outer end of the detection hole 30, a cover plate 32 with holes that presses the sealing ring and is fixed to the busbar 22, and two guide rods 31 symmetrically arranged on the upper and lower sides of the detection hole group. The guide rods 31 are sequentially sleeved with a number of clamping plates 27, springs 34 and fixed baffles 26 that are adapted to the detection holes 30. The fixed baffle 26 is fixed to the busbar 22, and the clamping plate 27 can slide along the guide rod 31. The clamping plate 27 realizes the compression of the step 331 on the male connector 33 inserted into the detection hole 30, thereby fixing the male connector. When the male connector 33 is inserted, the step 331 presses the card plate 27 to the side, and the card plate 27 compresses the spring 37 so that the card plate 27 moves to the side. At this time, the step 331 passes over the card plate 27 and enters the inner position of the card plate 27. Then the card plate 27 is reset under the action of the spring 34. At this time, the card plate 27 is outside the step 331, and the step 331 is pressed tightly, that is, the male connector 33 is fixed. The male connector 33 is prevented from falling off due to the high pressure during the detection, ensuring the normal detection.

[0052] like Figure 7 As shown, the card plate 27 is an L-shaped plate, one side of which is sleeved with the guide rod 31, and the other side is parallel to and opposite to the mouth of the detection hole 30 and has two C-shaped openings 35, which are respectively placed outside the two adjacent detection holes 30, and the male connector 33 passes through the C-shaped openings and is inserted into the detection hole 30. One of the C-shaped openings on the card plate 27 is used to press the step 331 on the male connector 33 under the elastic action of the spring 34, thereby fixing the male connector 33, and the other C-shaped opening is used to guide the male connector when it is inserted, but it will never press the step 331. On the one hand, the C-shaped opening opens a channel for the male connector to be inserted, which plays a guiding role, and on the other hand, it is used to press the step 331.

[0053] like Figure 7 As shown, the unloading module includes an unloading mechanism connected to the mounting mechanism A2, and the unloading mechanism can expose all the steps 331 on all the male connectors 33 installed on the mounting mechanism connected thereto at one time, so as to facilitate the male connector 33 to be pulled out and unloaded from the detection 30. The unloading method in the prior art, which requires the fingers to press and unlock the elastic buckle, is changed, and the unloading operation is simple and fast, and the labor intensity is greatly reduced. At the same time, the loading and unloading time is greatly shortened, and the detection operation efficiency is improved.

[0054] like Figure 7As shown, the unloading mechanism includes an unloading cylinder 29 connected to one end of the guide rod 31 and a fixing ring 25 sleeved on the guide rod 31 and the number of which is adapted to the detection hole 30. The fixing ring 25 is placed on the side of the clamping plate 27 away from the spring 34. The unloading cylinder 29 pushes the guide rod 31, and the guide rod 31 pushes the clamping plate 27 to compress the spring 34 through the fixing ring 25 thereon, exposing the step 331 on the male connector 33 pressed by the C-shaped mouth 35, so as to facilitate the male connector 33 to be pulled out of the detection hole 30 for unloading.

[0055] like Figure 6 and Figure 7 As shown, the unloading cylinder 29 pushes the guide rod 31. As the guide rod 31 moves to the right in the figure, the fixing ring 25 pushes the clamping plate 27 to the right, and the C-shaped opening on the left side of the clamping plate 27 evacuates the step 331 on the male connector 33, thereby exposing the step 331 on the connector 33, making it easier to directly pull the connector 33 out of the detection hole 30. When loading, the unloading cylinder 29 first moves to the left side in the figure to reset, the fixing ring 25 releases the card plate 27, and the card plate 27 moves to the left side under the action of the spring 34, and then the male connector 33 is manually inserted from the C-shaped opening position on the left side of the card plate 27. During the insertion, the step 331 squeezes the C-shaped opening position on the card plate 27, so that the card plate 27 moves to the right, and then the step 331 passes over the C-shaped opening position on the card plate 27, and then the card plate 27 drives the card plate 27 to reset under the action of the spring 34, and the C-shaped opening of the card plate 27 passes over the step 331 and is placed outside the step 331, so as to achieve the compression of the step 331, that is, to achieve the fixation of the male connector 33. In the whole process, the C-shaped opening on the right side of the card plate 27 does not exert force or action on the step 331, and the C-shaped opening on the right side of the card plate 27 only plays a guiding role to avoid interference when the male connector 33 is inserted.

[0056] The detection module in the present technical solution includes an air source, a supercharger 8 connected to the air source, and a leak detector; the air source is also connected to an air valve corresponding to the number of mounting mechanisms, each air valve is connected to an mounting mechanism, and after the male connector on the mounting mechanism is inspected, the air valve is started to blow air into the inspected pipeline to clean up garbage and waste generated and remaining in the pipeline during production, so as to prevent impurities in the pipeline from damaging the vehicle pipeline after the pipeline is installed on the vehicle.

[0057] The detection machine in this technology also includes an industrial computer, a printing module and an air purification module. The installation module, the unloading module, the detection module, the printing module and the air purification module are all controlled by the industrial computer. The printing module includes a laser printing component and a driving moving component. The industrial computer receives the qualified signal sent by the detection module, and then controls the moving component to move the laser printing component to the upper part of the qualified male connector, and prints a qualified mark on the male connector; while the laser printing component moves, the cigarette holder on the air purification module moves with the laser printing component to absorb the smoke generated by the printing part.

[0058] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention are implemented according to the conventional means in the field unless otherwise specified and limited.
