Description

Technical Field

[0001] The present invention relates to the technical field of air tightness detection, and specifically relates to a gas pipeline air tightness testing device and a testing method for a cartridge furnace. Background Art

[0002] A cassette stove is a portable cooking device that usually uses butane or propane gas as fuel. They are popular because of their small size, portability and ease of use. They are particularly suitable for cooking needs in outdoor activities, camping, picnics and emergencies.

[0003] The built-in gas pipeline of the cassette stove mainly transports the fuel from the gas tank to the burner head safely and stably to ensure the normal combustion of the flame. The gas pipeline structure is mainly composed of a main body and three openings, one for air intake, the second for exhaust, and the third for the assembly of the regulating valve. The produced gas pipeline needs to be tested for sealing before it is put into use. Since the gas component is mainly butane or propane gas, if the pipeline is unqualified and a leak occurs, it is very easy to explode when exposed to open flames. The test of pipeline sealing must be completed using designated equipment.

[0004] However, the existing gas pipeline sealing test equipment for cassette furnaces has the following shortcomings:

[0005] The main pipeline forming processes include cold drawing, hot rolling and welding, and each forming method will produce defective products with different probabilities, which cannot be identified by the naked eye. Traditional pipeline testing equipment is limited by its own structure and the effect achieved is relatively simple. In order to find the leaking position, multiple devices need to cooperate with each other and require a lot of manual assistance. Due to the low level of automation, batch testing steps are cumbersome and not conducive to the company's control of costs and pricing of later products.

[0006] Therefore, we propose a gas pipeline sealing test device and a test method for a cassette furnace to solve the above-mentioned problems. Summary of the invention

[0007] The purpose of the present invention is to provide a gas pipeline sealing test device and a test method for a cassette furnace. By setting up a joint collaborative mechanism, the mechanism includes three main parts. The first one completes the internal pressurization of the workpiece, and the actual value can be obtained through the hose connection. Then, the various components cooperate to ensure that the air pressure value inside the workpiece meets the standard conditions. The second one can cooperate with the submerged test to complete the image acquisition, position locking and defect marking in a distributed manner. The third one performs water stain treatment on the workpiece after measurement, so that each step is completed and the subsequent steps can be quickly connected to solve the problems raised by the above-mentioned background technology.

[0019] A method for testing a gas pipeline sealing test device for a cassette furnace comprises the following steps:

[0020] Step 1: Place the pipeline workpieces on the corresponding positioning fixtures in turn, fine-tune the position of each workpiece, and drive the first electric drive assembly, the second electric drive assembly and the third electric drive assembly to move the first gas joint, the second gas joint and the third gas joint toward the openings of the workpiece to complete the sealing of the openings of the workpiece.

[0021] Step 2: The relevant electrical module inside the electrical control box sets the air pressure value for each test. The gas compressed by the compressor unit is then evenly introduced into a corresponding workpiece through the connected hose and the first air guide joint. The compressed gas is then transferred to the cover in sequence through the connected hose, the third air guide joint and the fifth air guide joint. After the air pressure inside the workpiece and the cover stabilizes, the value measured by the air pressure sensor is the air pressure value inside the workpiece.

[0022] Step 3: The data can be quickly fed back to the relevant modules to determine the difference. If the internal air pressure is too low, the amount of compressed air introduced will be increased. Otherwise, the pressure will be slowly applied through the pressure relief pipe until the internal air pressure of the workpiece meets the set standard.

[0023] Step 4: Then turn on the pneumatic push rod to drive the workpieces in the positioning fixture to sink into the water source in the water storage tank, and the timing is determined by the relevant modules in the electrical control box.

[0024] Step 5: During the submersion time, the macro camera can move freely back and forth and left and right under the T-shaped top frame with the cooperation of multiple components to capture the water situation in real time. If there are no bubbles, and after the test time is reached, reset each component and further increase the air pressure intensity to complete the next submersion test. After all air pressure ranges have been tested, it means that all workpieces are qualified.

[0025] Step 6: If bubbles appear in the water within the field of view, the relevant module in the electrical control box determines the location of the bubble based on the image information and controls the opening of the excitation element. The relevant mechanical components work together to adjust the position of the transmitter head, accurately irradiate the emitted laser to the point where the bubble occurs, and quickly find inferior workpieces.

[0026] Step 7: After the test is completed and the workpiece is reset, high-speed airflow is emitted from each injection component. Through the coordination of mechanical components, the direction of airflow is freely controlled to complete the treatment of water stains on the surface of each workpiece.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] The present invention sets up a joint collaborative mechanism, which includes three main parts. The first one completes the internal pressurization of the workpiece, and the actual value can be obtained through the hose connection. Then, the various components cooperate to ensure that the air pressure value in the workpiece meets the standard conditions. The second one can cooperate with the submersion test to complete image acquisition, position locking and defect marking respectively. The third one performs water stain treatment on the workpiece after measurement, so that each step is completed and the subsequent steps can be quickly connected. By utilizing the main structure of the equipment, the various parts contained in the mechanism can be assembled one by one in sequence, and the system module is cooperated to analyze the obtained data to improve the response time of related components when replacing between steps, so that the equipment can independently complete the ability to control air pressure, capture air ports, screen targets and treat water stains, thereby effectively reducing labor costs and making subsequent products more cost-effective.

A group of second extension plates 919 are fixedly installed on the inner wall of the protective box 913, and a gas collecting tank 920 is fixedly installed inside each second extension plate 919. A sealing cover 921 is fixedly installed on the top of each gas collecting tank 920. An air pressure sensor 922 is fixedly inserted at the center of each sealing cover 921, and the sensing end of each air pressure sensor 922 is respectively placed inside a corresponding gas collecting tank 920, and a group of first information lines 923 are fixedly installed at the wiring terminal of each air pressure sensor 922, and the output end of each group of first information lines 923 is connected to the internal wiring of the equipment.

[0044] The effect achieved by the entire embodiment 1 is as follows: the positioning fixture 906 is used to fix the workpiece body. After the assembly is completed, the multiple openings set on the workpiece will be completely exposed and correspond to the first gas joint 905, the second gas joint 909 and the third gas joint 911 one by one. When the three are connected to the mechanical assembly, the sealing of each opening can be completed eventually. The compressed air flow can enter from the middle of the workpiece and diffuse to both sides, in order to ensure the gas filling density. Because the workpiece and the gas collection tank 920 can be directly connected through a hose, the air pressure measured by the air pressure sensor 922 is equivalent to the internal air pressure of the workpiece. The data can be shared with the relevant modules in the electrical control box 11, and the release amount of compressed air can be flexibly controlled to ensure that each workpiece test can be adjusted to the required air pressure range.

[0045] Embodiment 2, according to Figure 7 and Fig.10 As shown, a second expansion frame 928 is fixedly installed on the front surface of a sub-bracket 7, a group of first U-shaped frames 929 is fixedly installed on the outer wall of each second expansion frame 928, a first cross bar is movably inserted between the two sides of the inner wall of each first U-shaped frame 929, and an injection assembly 931 is fixedly sleeved on the outer wall of each first cross bar, a first drive assembly 930 is fixedly installed on one side of the outer wall of each first U-shaped frame 929, and the output end of each first drive assembly 930 is respectively connected to one end of the outer wall of a corresponding first cross bar, a group of second exhaust assemblies 932 is fixedly installed on the top of the protective box 913, and a group of third electric valves 933 are fixedly installed on the inner wall of the protective box 913, the exhaust end of each second exhaust assembly 932 is respectively connected to the intake end of a corresponding third electric valve 933, and the exhaust end of each third electric valve 933 is fixedly connected to a fourth hose 938, and the exhaust end of each fourth hose 938 is respectively connected to the intake end of a corresponding injection assembly 931.

[0046] The effect achieved by the entire embodiment 2 is as follows: since the equipment needs to be submerged in water, the purpose is that if there is gas leakage in the workpiece, it can be manifested in the form of bubbles in the water body, but after the workpiece is reset, a large amount of water stains will remain on its surface. The material of the pipeline workpiece is mostly metal. This part of the component can immediately complete the treatment of water stains on the surface of the workpiece through high-speed airflow after the workpiece is pulled away, and the various mechanical components are used in coordination during the process to repeatedly adjust the airflow derivation direction to ensure the adequacy of the water stain treatment and effectively avoid part of the water stains from penetrating into the interior of the workpiece when the workpiece is taken out. Since the anti-rust coating is usually provided on the outer wall of the workpiece, if the water stains that penetrate into the interior are not treated in time, it is easy to cause rust corrosion on the material.

[0047] Embodiment 3, according to Figure 3 , Figure 8 , Fig. 9 and Fig.10As shown, a hollow track 939 is fixedly installed at the bottom of the T-shaped top frame 6, a T-shaped slider 940 is movably installed inside the hollow track 939, a third external frame 941 is fixedly installed at the bottom of the T-shaped slider 940, a locking sleeve 942 and a second U-shaped joint 944 are respectively fixedly installed at the bottom of the third external frame 941, a macro camera 943 is provided inside the locking sleeve 942, a second cross bar is movably inserted between the two sides of the inner wall of the second U-shaped joint 944, and a square seat 945 is fixedly provided on the outer wall of the second cross bar, a transmitting head 948 is fixedly inserted inside the square seat 945, and an excitation element 946 is fixedly installed on the top of the square seat 945, and the excitation element The output end of 946 is connected to the input end of the transmitting head 948, the outer wall of the transmitting head 948 is fixedly sleeved with a cooling cover 947, the outer wall of the second U-shaped joint 944 is fixedly installed with a second driving component 949, the output end of the second driving component 949 is connected to one end of the outer wall of the second cross bar, the fourth electric drive component 950 is fixedly installed inside the T-shaped top frame 6, the inside of the T-shaped slider 940 is fixedly inserted with an associated bar 951, a parallel seat 952 is fixedly sleeved between the axial end of the fourth electric drive component 950 and one end of the outer wall of the associated bar 951, an inner slot 953 is opened on one side of the outer wall of the main bracket 3, and the parallel seat 952 is movably placed in the inner slot 953.

[0048] The effect achieved by the entire embodiment 3 is as follows: during the submerged test, the third external frame 941 and its connected components can reciprocate left and right at the bottom of the T-shaped top frame 6 under the cooperation of the driving component. On the one hand, the macro camera 943 captures the water surface conditions in real time, and the data is shared with the relevant modules in the electrical control box 11. If bubbles appear in some positions, the position where the bubbles occur is determined after judgment and analysis by the relevant modules, and then the corresponding mechanical components are controlled by the connected modules in the electrical control box 11 to accurately adjust the laser emission direction to ensure that the laser can accurately irradiate the bubble generation point. At the same time, the defective workpieces can be quickly screened out to facilitate direct viewing by relevant personnel.

[0049] The complete working principle of the equipment is as follows: in the preparation stage, the equipment is first moved to the designated working area, and the bottom of each load-bearing leg 13 is fully in contact with the ground, and a suitable depth of water is poured into the water storage tank 1, and then the external line is connected to the power supply of the equipment to provide energy for multiple electrical components therein. According to the opening position of the workpiece, each workpiece is initially placed in a corresponding positioning fixture 906, and the workpiece is manually fine-tuned to ensure that the first air connector 905, the second electric drive component 907 and the third air connector 911 can correspond to each opening one by one.

[0050] During the pressure stabilization stage, the start / stop button 12 is pressed to start the equipment. The first exhaust assembly 914 continuously introduces air into the compressor unit 915 to further complete the gas compression, the purpose of which is to increase the subsequent gas pressure. The first electric valve 918 can adjust the power supply in the fourth gas guide joint 917 to control the release amount of compressed air. The compressed air is released from each first gas guide joint 905 into a corresponding workpiece through the first hose 934 and the three-way assembly 935. Because the sealing cover 921 can be connected to the third hose 937, the compressed air can be simultaneously added to the workpiece and the gas collection tank 920. When the air in the workpiece is overflowing, the corresponding gas collection tank 920 is also quickly overflowing. The air pressure sensor The actual data measured by the device 922 can fully illustrate the internal air pressure state of the workpiece. Its value is analyzed and determined by the relevant modules in the electrical control box 11. If the air pressure is too high, the first electric valve 918 is closed to stop the release of compressed gas, and the second electric valve 926 is opened to slowly release the air pressure inside the workpiece. After the change value tends to the standard range, the internal channel of the expansion joint 925 is closed in time, otherwise the power of the compressor unit 915 is increased to further increase the air pressure. After the air pressure in each workpiece is stable, the pneumatic push rod 5 is turned on to drive the T-shaped top frame 6 and its connected components to move slowly downward until each workpiece is completely sunk into the water source in the water storage tank 1, and the timing is started by the relevant modules of the electrical control box 11.

[0051] During the marking stage, when the workpiece is submerged in water for testing, the fourth electric drive assembly 950 is turned on to allow its inner axis to retract and retract back and forth in the cavity, and act on the associated bar 951 and the parallel seat 952. The active connectivity of the T-shaped slider 940 and the hollow track 939 is utilized to slowly drive the third external frame 941 and its connected components to reciprocate left and right above the water storage tank 1. During the process, the macro camera 943 can capture the water surface image in real time and share the relevant modules in the electrical control box 11. If bubbles are generated in the water, the relevant modules can accurately determine the bubble generation point based on the image data, and control the opening of the second drive assembly 949, driving the square seat 945 in the second U-shaped joint 944 to rotate flexibly, thereby adjusting the angle of the transmitter head 948. After the position is locked, the excitation element 946 is turned on, and its energy is excited by the transmitter head 948. The laser can accurately and directly hit the bubble generation point to mark the target defective workpiece.

[0052] During the water stain treatment stage, when a batch of workpiece tests are completed, the pneumatic push rod 5 completes the reset of each component, and then each workpiece body is exposed again, and then each second exhaust component 932 is opened, and the incoming high-speed airflow is released by a corresponding third electric valve 933, and transported to each injection component 931 through the fourth hose 938, and finally the high-speed airflow is sprayed onto the target workpiece. This process starts the first drive component 930 and completes the angle adjustment of each injection component 931 to ensure that the water stain on the workpiece surface is fully treated.

[0053] During the removal stage, each second electric valve 926 is opened to continuously release the compressed air trapped in the workpiece and the cover 921. After the value returns to zero, the first electric drive component 904, the second electric drive component 907 and the square connector 908 are opened in sequence to pull the first air connector 905, the second air connector 909 and the third air connector 911 away from the opening of the workpiece in sequence. The workpiece loses its fixation and can be easily removed from the positioning fixture 906.

[0054] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
