DETAILED DESCRIPTION

[0027] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0029] In the description of the utility model, if there is a description of first and second, it is only for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0030] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0031] In the related art, air tightness testing is generally performed by manually connecting a test gas joint to the air filling port of the product for air tightness testing, and then injecting test gas into the product to test the air tightness of the product. During this testing process, the docking efficiency between the test gas joint and the air filling port of the product for air tightness testing is low.

[0032] Reference below Figures 1 to 4 The airtightness detection floating device according to the embodiment of the utility model is described.

[0033] like Figure 1 , Figure 2 As shown, the airtightness detection floating device according to the specific embodiment of the first aspect of the utility model includes a multi-dimensional driving mechanism, a floating docking joint 100, a position identification component 200 and a control component. The floating docking joint 100 and the position identification component 200 are arranged on the multi-dimensional driving mechanism, and can be driven by the multi-dimensional driving mechanism to move in multiple dimensions; the control component is respectively connected to the position identification component 200 and the multi-dimensional driving mechanism; the floating docking joint 100 can identify the position of the inflation port of the product to be tested and feed back to the control component, and the control component can drive the floating docking joint 100 to dock with the inflation port of the product to be tested through the multi-dimensional driving mechanism, thereby realizing the automatic docking of the detection air joint and the inflation port of the product to be tested, improving the efficiency of docking, and improving the efficiency of airtightness detection.

[0034] Specifically, the floating docking joint 100 is connected to the detection gas source through pipes, etc. The detection gas source is generally high-pressure gas. The position identification component 200 is driven to move by the multi-dimensional driving mechanism to identify the position of the inflation port of the product to be tested, and the position information is fed back to the control component. The control component drives the multi-dimensional driving mechanism to move the floating docking joint 100 to the position corresponding to the inflation port of the product to be tested and inserts the floating docking joint 100 into the inflation port of the product to be tested according to the position information fed back by the position identification component 200. The solenoid valve and other switch valves are opened to send the detection gas to the product, and then the air tightness of the product is determined by pressure detection (such as the pressure drop exceeds the set value and is determined to be unqualified for air tightness). After the detection is completed, the floating docking joint 100 is retracted by the multi-dimensional driving mechanism, that is, the detection process of the next product is entered. After automatic docking is realized, and rapid docking can be achieved, the efficiency of product air tightness detection can be greatly improved.

[0035] In some embodiments of the present invention, the floating docking joint 100 and the position identification component 200 are arranged on the multi-dimensional driving mechanism, and can be driven by the multi-dimensional driving mechanism to move in multiple dimensions, can realize the docking requirements in multiple directions, can meet the air tightness detection requirements of different products, and no manual intervention is required.

[0036] like Figure 4As shown, in some embodiments of the utility model, the floating docking joint 100 is provided with a gas channel, one end of the gas channel is a detection gas inlet 101, and the other end of the gas channel is a docking port 102 docked with the inflation port of the product to be tested. When working, a pipe for conveying the detection gas is connected to the detection gas inlet 101, and in conjunction with a switch valve such as a solenoid valve, the detection gas can be injected into the product after the docking port 102 is docked with the inflation port of the product to be tested.

[0037] Specifically, Figure 4 As shown, the floating butt joint 100 is an elongated structure, the gas channel penetrates the floating butt joint 100 along the length direction of the floating butt joint 100 , and the detection gas inlet 101 and the docking port 102 are respectively located at two ends of the floating butt joint 100 .

[0038] In some embodiments of the present invention, the inflation port of the product to be tested is generally an external connector on the product, corresponding to the docking port 102 .

[0039] It can be understood that in some embodiments of the present invention, a docking port 102 that docks with the inflation port of the product to be tested may be provided only on the floating docking joint 100, and a pipe for conveying the detection gas may be directly connected to the docking port 102, which may also meet the delivery requirements of the detection gas.

[0040] In some embodiments of the present invention, the floating docking joint 100 can be configured with a solenoid valve to control the on-off of the gas channel. The solenoid valve is connected to a control component. When the floating docking joint 100 is docked with the inflation port of the product to be tested, the control component can control the solenoid valve to open and inject the test gas into the product.

[0041] It is conceivable that, in some embodiments of the present invention, a switch valve such as a solenoid valve for controlling the delivery of the detection gas may also be provided on the pipe for delivering the detection gas, which will not be described in detail herein.

[0042] In some embodiments of the utility model, a clamping mechanism capable of embracing the inflation port of the product to be tested is configured at the docking port 102, so as to clamp the inflation port of the product to be tested after the floating docking head 100 is docked with the inflation port of the product to be tested, thereby improving air tightness and reducing the occurrence of air leakage at the interface position.

[0043] like Figure 4 As shown, in some embodiments of the present invention, the clamping mechanism is a pneumatic tensioning assembly, and the floating docking joint 100 is provided with a driving air inlet 103 connected to the pneumatic tensioning assembly. By injecting high-pressure air into the driving air inlet 103, the pneumatic tensioning assembly can tighten the inflation port of the product to be tested, thereby improving the air tightness of the interface position.

[0044] Specifically, the pneumatic tensioning component can be an annular airbag or a seal that can be driven by a pneumatic expansion component. The pneumatic tensioning component has an inner ring for inserting the inflation port of the product to be tested. After the inflation port of the product to be tested is inserted into the above-mentioned inner ring, the airbag or the pneumatic expansion component is injected with high-pressure gas and expands and deforms. At the same time, the inner ring contracts to hold the inflation port of the product to be tested, thereby achieving the effect of improving the air tightness of the interface position.

[0045] In some embodiments of the present invention, the interior of the floating docking joint 100 is a hollow structure, and the driving air inlet 103 is connected to the pneumatic tensioning assembly through the hollow structure inside the floating docking joint 100 to realize air supply to the pneumatic tensioning assembly.

[0046] Specifically, the interior of the floating butt joint 100 is a hollow structure, and the driving air inlet 103 is preferably an air pipe joint. The driving air inlet 103 is connected to the hollow structure inside the floating butt joint 100, and at the same time, the hollow structure inside the floating butt joint 100 is connected to the pneumatic tensioning assembly. That is, the hollow structure inside the floating butt joint 100 is used to form a connecting channel connecting the driving air inlet 103 and the pneumatic tensioning assembly, thereby realizing air supply to the pneumatic tensioning assembly, and the structure is simpler and more compact.

[0047] During operation, a driving gas such as high-pressure gas is connected to the driving gas inlet 103 through a pipeline. The pipeline or the floating joint 100 is provided with a solenoid valve or other switch valve for controlling the on and off of the driving gas. When the floating joint 100 is docked with the inflation port of the product to be tested, the control component or other control module opens the solenoid valve or other switch valve of the driving gas. The high-pressure gas is injected into the pneumatic tensioning component through the driving gas inlet 103 and the hollow structure inside the floating joint 100 in turn, driving the pneumatic tensioning component to contract and hold the inflation port of the product to be tested, thereby improving the airtightness of the interface position, ensuring the sealing effect during detection, and improving the accuracy of detection.

[0048] It can be understood that in some embodiments of the present invention, the docking port 102 may be provided with an elastic sealing member such as a sealing ring to improve the air tightness of the interface position by tightly fitting with the inflation port of the product to be tested.

[0049] In some embodiments of the utility model, the delivery pipelines of the driving gas and the detection gas are both equipped with solenoid valves, which are connected to the control component. When the floating docking joint 100 is docked with the inflation port of the product to be tested, the control component controls the opening of the solenoid valve of the driving gas, so that the pneumatic tightening component clamps the inflation port of the product to be tested to avoid interface leakage. Then the solenoid valve of the detection gas is opened to deliver the detection gas into the product. The control component determines the air tightness of the product by monitoring the pressure changes. After the detection is completed, the corresponding pressure relief is performed. The entire process can be automated, which greatly improves the efficiency of product air tightness detection and has high detection accuracy.

[0050] like Figure 1 , Figure 2 , Figure 3 As shown, in some embodiments of the present invention, the floating docking head 100 and the position identification assembly 200 are arranged side by side, so that the floating docking head 100 and the position identification assembly 200 can share a multi-dimensional driving mechanism, making the structure simpler and the control more convenient.

[0051] Specifically, the floating docking head 100 and the position identification component 200 have set directionality, and the side-by-side arrangement of the two means that the two directions are roughly the same; the airtightness detection floating device is generally arranged on one side of the product conveyor line, and the detection and docking of the inflation port of the product to be tested are both directed towards the product. The floating docking head 100 and the position identification component 200 are arranged side by side on the side of the product conveyor line, which can simultaneously meet the detection and docking requirements of the inflation port of the product to be tested, and simplify the driving structure.

[0052] In some embodiments of the present invention, the position identification component 200 is a visual identification unit, which can determine the position of the inflation port on the product through visual recognition.

[0053] Specifically, the position identification component 200 can directly determine the position of the inflation port based on its shape, or it can determine the position of the inflation port by detecting the position of the product (the position of the inflation port on the product is fixed, and necessary compensation can be set in the control component).

[0054] It can be understood that in some embodiments of the present invention, the position identification component 200 can also be an infrared detection probe, and a sensing unit corresponding to the infrared detection probe is set on the product or the product placement fixture. By moving the infrared detection probe to identify and dock with the sensing unit, the position of the product or the inflation port can also be determined.

[0055] like Figure 1 , Figure 2 , Figure 3 As shown, in some embodiments of the present invention, the multi-dimensional driving mechanism includes a floating workbench 301, and the floating docking head 100 and the position identification component 200 are arranged side by side on the floating workbench 301, so as to realize the side-by-side arrangement of the floating docking head 100 and the position identification component 200.

[0056] It can be understood that in some embodiments of the present invention, the floating docking head 100 and the position identification component 200 can be independently connected to the multi-dimensional driving mechanism and maintain the same orientation, and the floating docking head 100 and the position identification component 200 can also be arranged side by side.

[0057] like Figure 1 , Figure 2 , Figure 3 As shown, in some embodiments of the present invention, the floating workbench 301 is provided with a first Y-axis driving assembly 310, and the floating docking head 100 is connected to the first Y-axis driving assembly 310. The first Y-axis driving assembly 310 can drive the floating docking head 100 to move relative to the inflation port of the product to be tested to achieve docking and separation.

[0058] like Figure 2 As shown, in some embodiments of the utility model, the floating workbench 301 is provided with a second Y-axis drive assembly 320, and the position identification assembly 200 is connected to the second Y-axis drive assembly 320. The second Y-axis drive assembly 320 can drive the position identification assembly 200 to move relative to the inflation port of the product to be tested, and can adjust the distance between the position identification assembly 200 and the product according to different products to improve the accuracy of identification, and after the identification is completed, the second Y-axis drive assembly 320 can drive the position identification assembly 200 to retract, thereby reducing the occurrence of collisions between the position identification assembly 200 and other components during the movement and docking of the floating docking head 100.

[0059] like Figure 1 , Figure 2 As shown, in some embodiments of the utility model, the multi-dimensional driving mechanism also includes an X-axis driving component 330 and a Z-axis driving component 340, the Z-axis driving component 340 is connected to the X-axis driving component 330, and the floating workbench 301 is connected to the Z-axis driving component 340, and the two-axis driving of the floating workbench 301 is realized by the X-axis driving component 330 and the Z-axis driving component 340, and the three-axis driving of the floating docking head 100 and the position identification component 200 is realized in cooperation with the first Y-axis driving component 310 and the second Y-axis driving component 320.

[0060] Specifically, the directions of the X-axis, Y-axis, and Z-axis are as follows: Figure 1 As shown, the X-axis driving assembly 330 can drive the Z-axis driving assembly 340 to translate along the X-axis direction, and the Z-axis driving assembly 340 can drive the floating workbench 301, the first Y-axis driving assembly 310, and the second Y-axis driving assembly 320 to move along the Z-axis, thereby meeting the requirements of three-axis mobile drive.

[0061] Of course, in the specific implementation process, the multi-dimensional driving mechanism can also be a driving mechanism of other structures, such as a four-axis manipulator, a five-axis manipulator, etc., which will not be described in detail here.

[0062] In some embodiments of the present invention, the first Y-axis drive assembly 310, the second Y-axis drive assembly 320, the X-axis drive assembly 330, and the Z-axis drive assembly 340 can be linear drive mechanisms such as cylinder mechanisms, synchronous belt mechanisms, screw mechanisms, or spur rack mechanisms.

[0063] It is conceivable that in some embodiments of the present invention, the second Y-axis drive assembly 320 may not be configured, and the position identification assembly 200 only needs X-axis drive and Z-axis drive to meet the identification requirements of the inflation port of the set product.

[0064] It can be understood that in some embodiments of the present invention, the floating docking head 100 and the position identification component 200 can be independently configured with a multi-dimensional driving mechanism, that is, two sets of multi-dimensional driving mechanisms are configured to drive the floating docking head 100 and the position identification component 200 respectively, which can also meet the docking and identification requirements.

[0065] The technical features of the above embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0066] Of course, the present invention is not limited to the above-mentioned embodiments, and technicians familiar with the field may make equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
