Description

Technical Field

[0001] The present invention relates to the technical field of detection equipment, and in particular to an automatic detection equipment for shell deformation used in the production of airtightness detectors. Background Art

[0002] The sealing tester is also called an airtightness tester or a leakage tester. It is mainly used for sealing tests of packaging bags, bottles, tubes, cans, boxes, etc. in industries such as food, pharmaceuticals, medical devices, daily chemicals, automobiles, electronic components, stationery, and consumer electronics. In the production process of the airtightness tester, it is necessary to detect the deformation of the airtightness tester shell. At present, the airtightness tester is placed on a conveyor belt, and the shell of the airtightness tester is photographed by a camera. Then, the surface of the shell of the airtightness tester is analyzed to obtain the deformation amount. The operation is simple and the degree of intelligence is high.

[0003] However, in the actual inspection process, if the inspection is only carried out through a camera, it is very likely that unqualified parts will be missed due to the negligence of the inspectors, and during the inspection, a certain amount of pressure and temperature are sometimes applied to the shell of the airtightness tester to simulate the use environment for inspection. However, this inspection method applies a certain amount of pressure and temperature, which can only simulate the use environment of the shell of the airtightness tester under specific circumstances when it is used. The inspection result is also not representative. In addition, during the inspection process, when the shell of the airtightness tester is deformed, it is very likely that only the protective film of the shell of the airtightness tester is bulged, and the shell of the airtightness tester itself is not deformed, resulting in misjudgment.

DETAILED DESCRIPTION

[0034] See also Figure 1-Figure 16 , an automatic shell deformation detection device for air tightness tester production, comprising a workbench 1, a transmission component 2, and a camera 22, wherein the transmission component 2 is fixedly installed in the workbench 1, and a top plate 3 is fixedly connected to the upper side of the workbench 1 through a bracket;

[0035] First, the camera 22 is installed on the lower side of the top plate 3. Secondly, the transmission component 2 is composed of a transmission chain plate and a plurality of transmission rods. The housing of the airtightness detector to be tested is fixed on the transmission chain plate, and the transmission rod is started to drive the housing of the airtightness detector to move on the transmission chain plate. Under the action of the camera 22, the surface of the housing of the airtightness detector is photographed, and the color and roughness of the surface of the housing of the airtightness detector are analyzed, so as to know whether the housing of the airtightness detector is deformed, and the deformation size of the housing of the airtightness detector can be measured. The above are all existing technologies and no unnecessary elaboration is made.

[0036] like Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 A simulation component for simulating the use environment of the airtightness detector housing is installed on the lower side of the top plate 3, and the simulation component includes a motor 11, a rotating plate 20, a center plate 7, a fixed frame 15, a pressure plate 16, and a heating rod 24. A threaded rod 5 is threadedly sleeved on the upper side of the top plate 3, and a slide plate 6 is rotatably connected to the lower side of the threaded rod 5. The slide plate 6 is slidably connected to multiple groups of brackets, and two groups of fixed clamping plates 9 are symmetrically fixedly connected to the lower side of the slide plate 6. The motor 11 is located between the two groups of fixed clamping plates 9, and the motor 11 is fixedly installed on the inner side of one of the fixed clamping plates 9. The output end of the motor 11 is fixedly connected to a rotating shaft 12, and the rotating plate 20 is fixedly sleeved on the outer side of the rotating shaft 12. The center plate 7 is located on the lower side of the rotating plate 20 and abuts against the rotating plate 20. The center plate 7 is connected to the slide plate 6 through multiple groups of telescopic sleeves 13, and the center plate 7 is connected to the slide plate 6 through multiple groups of reset springs 1 4 is connected to the slide plate 6, there are multiple groups of cameras 22, the fixed frame 15 is fixedly installed on the lower side of the center plate 7, the multiple groups of cameras 22 are fixedly installed on the lower side of the center plate 7, and the multiple groups of cameras 22 are symmetrically arranged on both sides of the fixed frame 15, the pressure plate 16 is slidably sleeved in the fixed frame 15, the upper side of the pressure plate 16 is fixedly connected with the positioning plate 21 through multiple groups of extrusion springs 25, a heating chamber 18 is opened in the pressure plate 16, the number of heating rods 24 is multiple groups, and the multiple groups of heating rods 24 are fixedly installed in the heating chamber 18, the lower side of the center plate 7 is symmetrically fixedly connected with multiple groups of fixed cylinders 10, the multiple groups of fixed cylinders 10 are slidably sleeved with moving cylinders 17, the moving cylinders 17 penetrate the fixed cylinders 10, the lower side of the moving cylinders 17 is fixedly connected with a contact plate 23, and a pressure sensor 4 is fixedly connected between the moving cylinder 17 and the side wall of the center plate 7;

[0037] First, the heating rod 24 is a common resistance heater in real life. When the heating rod 24 is energized, the corresponding material can be heated. Secondly, the pressure sensor 4 is a commonly used displacement sensor. One end of the displacement sensor is fixed on the upper side of the center plate 7, and the other end of the displacement sensor is fixed on the outside of the moving cylinder 17. When the moving cylinder 17 moves up and down relative to the center plate 7, the value of the displacement sensor changes. When the moving cylinder 17 moves upward relative to the center plate 7, the value of the pressure sensor 4 gradually increases. When the moving cylinder 17 moves downward relative to the center plate 7, the value of the pressure sensor 4 gradually decreases. The signal is then transmitted to the controller through the pressure sensor 4 to control the bell light to alarm. , and then remind the corresponding staff. This is the existing technology and no unnecessary elaboration is made. When the airtightness detector housing is tested, the airtightness detector housing is photographed by the camera 22 when passing through the lower side of the fixed frame 15, and then the airtightness detector housing can be tested. At this time, the contact plate 23 is also located on the upper side of the airtightness detector housing and abuts against the airtightness detector housing. Before the airtightness detector housing and the contact plate 23 abut against each other, the pressure sensor 4 and the fixed end of the moving cylinder 17 are located on the upper side of the fixed cylinder 10 and abut against the fixed cylinder 10. After the airtightness detector housing and the contact plate 23 abut against each other, the contact plate 23 and the moving cylinder 17 will move upward as a whole, and the pressure sensor 4 becomes Figure 4 The value of the pressure sensor 4 changes. In the following inspection process of the airtightness detector shell, if the flatness of the airtightness detector shell is high and there are no protrusions or depressions, the value of the pressure sensor 4 will not change. When there are protrusions or depressions on the surface of the airtightness detector shell, the contact plate 23 drives the movable cylinder 17 to move upward or downward relative to the fixed cylinder 10, and the value of the pressure sensor 4 changes, indicating that the shell of the airtightness detector shell is deformed. The camera 22 is used for detection to improve the detection effect. Secondly, the side wall of the slide plate 6 is provided with a groove, and the bracket and the inner wall of the groove are against each other. Under the restriction of the bracket, the slide plate 6 can only move up and down relative to the top plate 3. Then, before the airtightness detector shell is inspected, the threaded rod 5 is rotated first, and the threaded rod 5 drives the slide plate 6 to move up and down, and the slide plate 6 drives the center plate 7 to move up and down until the position of the center plate 7 meets the working requirements. Then, in the process of inspecting the airtightness detector shell, the motor 11 is started, and the motor 11 drives the rotating shaft 12 to rotate, and the rotating shaft 12 drives the rotating plate 20 to rotate. Under the action of the reset spring 14, the rotating plate 20 is always against the center plate 7, and under the action of the telescopic sleeve 13, the center plate 7 can only move up and down relative to the slide plate 6. Due to the special shape of the rotating plate 20, the structural features and shape of the rotating plate 20 refer to the attached Figure 5 As shown, since the center plate 7 is always against the rotating plate 20, as shown in FIG. Fig.16As shown, when the arc surface of the rotating plate 20 farthest from the center of the circle abuts against the center plate 7 (denoted as W1), the center plate 7 is at the lowermost side; when the arc surface of the rotating plate 20 closest to the center of the circle abuts against the center plate 7 (denoted as W2), the center plate 7 is at the uppermost side; when the rotating plate 20 changes from W1 to W2 (or from W2 to W1) (denoted as W3), the center plate 7 is in an upward or downward moving state, resulting in that during the transportation of the airtightness detector housing, the center plate 7 will repeat the movement of "uppermost side-downward movement-lowermost side-upward movement", and the center plate 7 drives the fixed frame 15 and the pressure plate 16 to repeat the same movement. When the fixed frame 15 is at the lowermost side, the fixed frame 15 just abuts against the airtightness detector housing, the contact plate 23 abuts against the airtightness detector housing, the pressure plate 16 abuts against the airtightness detector housing, and the extrusion spring 25 is compressed to form pressure on the airtightness detector housing. And during this process, the heating rod 24 is always in the open state, the pressure plate 16 and the airtightness tester shell are against each other, which will also form a heating effect on the airtightness tester shell, simulating that when the airtightness tester shell is working, the internal pressure changes, and the airtightness tester shell is squeezed. And as the pressure changes, the temperature of the internal environment of the airtightness tester shell also changes, forming a simulation of the use environment of the airtightness tester shell, thereby improving the detection effect. When the fixed frame 15 is in other motion states, the moving cylinder 17 moves downward relative to the fixed cylinder 10 under the action of its own gravity. If the airtightness tester shell is not deformed, the values ​​of all pressure sensors 4 will decrease at the same time. If the airtightness tester shell is deformed, the values ​​of all pressure sensors 4 will decrease at the same time. The values ​​of some pressure sensors 4 will not change, thereby reminding the corresponding staff.

[0038] like Figure 8 , Fig. 9 , Fig.10 , Fig.11 , Fig.12, a regulating assembly 8 for regulating the position of the positioning plate 21 is installed in the center plate 7, and the regulating assembly 8 includes a circular plate 806 and a power rod 826. A third gear 805 is fixedly sleeved on the outer side of the rotating shaft 12, and a transmission rod 803 is rotatably connected to the inner side of one of the fixed splints 9. Two second gears 804 are fixedly sleeved on the outer side of the transmission rod 803. The third gear 805 meshes with one of the second gears 804. A rotating rod 801 is also rotatably connected to the inner side of one of the fixed splints 9. The circular plate 806 is fixedly connected to the rotating rod 801. The outer side of the rotating rod 801 is fixedly sleeved with a first gear 802. The first gear 805 is fixedly sleeved on the outer side of the rotating rod 801. 02 is meshed with another second gear 804, the outer side of the circular plate 806 is fixedly connected with a first connecting rod 807, the outer side of the first connecting rod 807 is rotatably sleeved with a first connecting plate 808, the outer side of the first connecting plate 808 is fixedly connected with a second connecting rod 821, the outer side of the second connecting rod 821 is rotatably sleeved with a second connecting plate 809, the second connecting plate 809 is rotatably sleeved with a connecting tube 822, the connecting tube 822 is rotatably sleeved with an extension rod 810, the lower side of the connecting tube 822 is fixedly connected with a power rod 826 through a connecting rod 811, a cavity 812 is opened in the center plate 7, and the power rod 826 runs through the cavity The upper side wall of cavity 812 is slidably connected to cavity 812, the lower side of power rod 826 is fixedly connected to power spring 825, the lower side of power spring 825 is fixedly connected to driven rod 827, the lower side of driven rod 827 passes through the lower side wall of cavity 812, and driven rod 827 is fixedly connected to positioning plate 21; the lower side of slide plate 6 is fixedly connected to return rod 815, the outer side of return rod 815 is rotatably sleeved with guide cylinder 816, the outer side of guide cylinder 816 is fixedly sleeved with two fourth gears 817, the upper side of center plate 7 is fixedly connected to fixed rack 819, the fixed rack 819 is meshed with one of the fourth gears 817 , the outer side of another fourth gear 817 is meshedly connected with a moving rack 818, one side of the moving rack 818 is slidably connected with a guide plate 820, the side of the guide plate 820 away from the moving rack 818 is fixedly connected with an auxiliary frame 814, the lower side of the auxiliary frame 814 is fixedly connected with a moving frame 813 through an auxiliary rod 824, the moving frame 813 is located in the cavity 812 and is slidably connected to the cavity 812, the driven rod 827 runs through the moving frame 813, both sides of the driven rod 827 are provided with through grooves 828, four card plates 829 are symmetrically fixedly connected in the moving frame 813, and the card plates 829 and the through grooves 828 are slidably connected;

[0039] First, the first gear 802, the two second gears 804, and the third gear 805 are of different sizes. When the motor 11 drives the rotating shaft 12 to rotate, the first gear 802, the second gear 804, the transmission rod 803, and the third gear 805 drive the rotating rod 801 to rotate. The rotating rod 801 rotates at a different speed than the rotating shaft 12. Then, under the action of the circular plate 806, the first connecting rod 807, the second connecting rod 821, the first connecting plate 808, and the second connecting plate 809, the circular plate 806 rotates. In the process of the connecting tube 822 driving the power rod 826 to move up and down, when it is in the W1 and W2 states, there are two clamping plates 829 located in the through slot 828, and the position of the driven rod 827 does not change. When it is in the W3 state, the center plate 7 moves downward as an example (the principle of the center plate 7 moving up and down is similar, so only one direction is taken as an example). The center plate 7 moves downward to Fig.10 Based on the direction of the fixed rack 819, the fixed rack 819 drives the movable rack 818 to move rightward through the fourth gear 817, and the movable rack 818 drives the auxiliary frame 814 to move rightward through the guide plate 820. The auxiliary frame 814 drives the movable frame 813 to move rightward through the auxiliary rod 824. Fig.11 Based on the direction of Fig.10 The moving frame 813 moving rightward in Fig.11 The moving frame 813 moves forward, and the moving frame 813 drives the card plate 829 to move forward. When the driven rod 827 is between the two card plates 829, the restriction of the card plate 829 is lost, the elastic force of the power spring 825 is released, and the driven rod 827 moves upward or downward. Then, when the other two card plates 829 enter the through groove 828, the power rod 826 is restricted by the card plate 829 again. In this process, the position of the power rod 826 changes, resulting in a change in the position of the positioning plate 21. In the subsequent process of the pressure plate 16 moving upward relative to the fixed frame 15, the deformation of the extrusion spring 25 will change, and the pressure on the housing of the airtightness detector will also change, which will result in that in the process of testing the housing of the airtightness detector, the pressure of the simulated use environment of the housing of the airtightness detector is different each time the test is performed, thereby ensuring the diversity and accuracy of the test results of the housing of the airtightness detector.

[0040] A limit rod 823 is fixedly connected between the two circular rods 815, and the movable rack 818 passes through the limit rod 823 and is slidably connected to the limit rod 823 to determine and limit the movement trajectory of the movable rack 818, so that the movable rack 818 is always in meshing state with the fourth gear 817.

[0041] like Fig.13 , the positioning plate 21 and the pressure plate 16 are fixedly sleeved with a transmission tube, a hose 19 is fixedly connected between the two transmission tubes, and a conical block 830 is fixedly connected to the lower side of the center plate 7. The conical block 830 and the upper transmission tube are matched. First, after the position adjustment of the positioning plate 21 is completed, since the position of the conical block 830 remains unchanged, the transmission tube will move up and down relative to the conical block 830, thereby adjusting the actual opening size of the transmission tube. When the heating rod 24 is used for heating, since the heating chamber 18 is under the action of the heating rod 24, the temperature of the heating chamber 18 is higher than the external environment temperature, and the opening size of the transmission tube will affect the internal temperature of the heating chamber 18. The larger the opening, the stronger the flowability with the external environment, resulting in a lower internal temperature of the heating chamber 18, which will cause the heating temperature of the airtightness detector housing to change, and ultimately make the test results convincing.

[0042] like Fig.14 , Fig.15 , both ends of the extension rod 810 are fixedly connected with a pressure plate 833, a tapered rod 831 is slidably sleeved in the moving cylinder 17, and a contact block 832 is fixedly connected to the upper side of the tapered rod 831. The pressure plate 833 is located on the upper side of the contact block 832, and the contact block 832 is connected to the moving cylinder 17 through a connecting spring 834. In the process of testing the shell of the airtightness detector, the shell of the airtightness detector is likely to bulge. There are two reasons for the bulge. One is that the shell of the airtightness detector is deformed as a whole, and the other is that the protective film on the surface of the shell of the airtightness detector is heated and deformed. When the shell of the airtightness detector is bulged, the contact plate 23 will drive the moving cylinder 17 to move upward, and the moving cylinder 17 is connected to the connecting spring 834. 834 drives the contact block 832 to move upward, and the contact block 832 and the pressure plate 833 are against each other. Since the extension rod 810 keeps moving up and down, the extension rod 810 drives the pressure plate 833 to move downward, and the pressure plate 833 drives the contact plate 23 to move downward, forming a knock on the protrusion of the air tightness tester housing. If the protective film is deformed, continuous knocking will puncture the protective film, the protrusion will disappear, and the contact plate 23 as a whole will return to its original position relative to the fixed tube 10. At this time, the value of the corresponding pressure sensor 4 changes. If the protective film is not deformed, continuous knocking will not cause the contact plate 23 as a whole to return to its original position relative to the fixed tube 10, and the value of the corresponding pressure sensor 4 will not change, thereby reminding the corresponding staff.

[0043] In the present invention, the housing of the airtight detector to be tested is fixed on the transmission chain plate by bolts and other mechanisms, and the transmission rod is started to drive the housing of the airtight detector to move on the transmission chain plate. Under the action of the camera 22, the surface of the housing of the airtight detector is photographed, and the color and roughness of the surface of the housing of the airtight detector are analyzed, so as to know whether the housing of the airtight detector is deformed, and the deformation size of the housing of the airtight detector can be measured. The above are all prior arts and no unnecessary elaboration is made. When the housing of the airtight detector is tested, When the airtightness detector housing passes the lower side of the fixed frame 15, it is photographed by the camera 22, and then the airtightness detector housing can be tested. At this time, the contact plate 23 is also located on the upper side of the airtightness detector housing and abuts against the airtightness detector housing. Before the airtightness detector housing and the contact plate 23 abut against each other, the pressure sensor 4 and one end of the movable cylinder 17 are located on the upper side of the fixed cylinder 10 and abut against the fixed cylinder 10. After the airtightness detector housing and the contact plate 23 abut against each other, the contact plate 23 and the movable cylinder 17 will move upward as a whole, and the pressure sensor becomes Figure 4 The value of the pressure sensor 4 changes. In the following inspection process of the airtightness detector shell, if the flatness of the airtightness detector shell is high and there are no protrusions or depressions, the value of the pressure sensor 4 will not change. When there are protrusions or depressions on the surface of the airtightness detector shell, the contact plate 23 drives the movable cylinder 17 to move upward or downward relative to the fixed cylinder 10, and the value of the pressure sensor 4 changes, indicating that the shell of the airtightness detector shell is deformed. The camera 22 is used for detection to improve the detection effect. Secondly, the side wall of the slide plate 6 is provided with a groove, and the bracket and the inner wall of the groove are against each other. Under the restriction of the bracket, the slide plate 6 can only move up and down relative to the top plate 3. Then, before the airtightness detector shell is inspected, the threaded rod 5 is rotated first, and the threaded rod 5 drives the slide plate 6 to move up and down, and the slide plate 6 drives the center plate 7 to move up and down until the position of the center plate 7 meets the working requirements. Then, in the process of inspecting the airtightness detector shell, the motor 11 is started, and the motor 11 drives the rotating shaft 12 to rotate, and the rotating shaft 12 drives the rotating plate 20 to rotate. Under the action of the reset spring 14, the rotating plate 20 is always against the center plate 7, and under the action of the telescopic sleeve 13, the center plate 7 can only move up and down relative to the slide plate 6. Due to the special shape of the rotating plate 20, the structural features and shape of the rotating plate 20 refer to the attached Figure 5 As shown, since the center plate 7 is always against the rotating plate 20, as shown in FIG. Fig.16As shown, when the arc surface of the rotating plate 20 farthest from the center of the circle abuts against the center plate 7 (denoted as W1), the center plate 7 is at the lowermost side; when the arc surface of the rotating plate 20 closest to the center of the circle abuts against the center plate 7 (denoted as W2), the center plate 7 is at the uppermost side; when the rotating plate 20 changes from W1 to W2 (or from W2 to W1) (denoted as W3), the center plate 7 is in an upward or downward moving state, resulting in that during the transportation of the airtightness tester housing, the center plate 7 will repeat the movement of "uppermost side-downward movement-lowermost side-upward movement", and the center plate 7 drives the fixed frame 15 and the pressure plate 16 to repeat the same movement. When the fixing frame 15 is at the lowermost side, the fixing frame 15 just contacts the outer shell of the airtight detector, the contact plate 23 contacts the outer shell of the airtight detector, the pressure plate 16 contacts the outer shell of the airtight detector, and the extrusion spring 25 is compressed to form pressure on the outer shell of the airtight detector. In this process, the heating rod 24 is always in the open state, and the pressure plate 16 contacts the outer shell of the airtight detector, which also forms a heating effect on the outer shell of the airtight detector. When the outer shell of the airtight detector is working, the internal pressure changes, the outer shell of the airtight detector is squeezed, and as the pressure changes, the temperature of the internal environment of the outer shell of the airtight detector changes. The degree also changes, forming a simulation of the use environment of the airtightness detector housing, thereby improving the detection effect. When the fixed frame 15 is in other motion states, the movable cylinder 17 moves downward relative to the fixed cylinder 10 under the action of its own gravity. If the airtightness detector housing does not deform, the values ​​of all the pressure sensors 4 decrease at the same time. If the airtightness detector housing deforms, the values ​​of all the pressure sensors 4 decrease at the same time. Some of the pressure sensors 4 will not change, thereby reminding the corresponding staff to adjust the circular plate 806, the first connecting rod 807, the second connecting rod 821, and the first connecting plate 808. , under the action of the second connecting plate 809, during the rotation of the circular plate 806, the connecting cylinder 822 and the extension rod 810 will be driven to move up and down as a whole. This is a more common four-bar mechanism transmission method, and no unnecessary details will be given. During the process of the connecting cylinder 822 driving the power rod 826 to move up and down, when in the W1 and W2 states, there will be two clamping plates 829 located in the through groove 828, and the position of the driven rod 827 will not change. When in the W3 state, the downward movement of the center plate 7 is taken as an example for explanation (the principle of the upward and downward movement of the center plate 7 is similar, so only one direction is taken as an example). The center plate 7 moves downward to Fig.10 Based on the direction of the fixed rack 819, the fixed rack 819 drives the movable rack 818 to move rightward through the fourth gear 817, and the movable rack 818 drives the auxiliary frame 814 to move rightward through the guide plate 820. The auxiliary frame 814 drives the movable frame 813 to move rightward through the auxiliary rod 824. Fig.11 Based on the direction of Fig.10The moving frame 813 moving rightward in Fig.11 The moving frame 813 moves forward, and the moving frame 813 drives the card plate 829 to move forward. When the driven rod 827 is between the two card plates 829, the restriction of the card plate 829 is lost, the elastic force of the power spring 825 is released, and the driven rod 827 moves upward or downward. Then, when the other two card plates 829 enter the through groove 828, the power rod 826 is restricted by the card plate 829 again. In this process, the position of the power rod 826 changes, resulting in a change in the position of the positioning plate 21. In the subsequent process of the pressure plate 16 moving upward relative to the fixed frame 15, the deformation of the extrusion spring 25 will change, and the pressure on the housing of the airtightness detector will also change. Changes occur, resulting in that during the process of testing the shell of the airtight detector, the pressure of the simulated use environment of the shell of the airtight detector is different each time the test is performed, thereby ensuring the diversity and accuracy of the test results of the shell of the airtight detector. After the position adjustment of the positioning plate 21 is completed, since the position of the conical block 830 remains unchanged, the transmission tube will move up and down relative to the conical block 830, thereby adjusting the actual opening size of the transmission tube. When the heating rod 24 is used for heating, since the heating chamber 18 is under the action of the heating rod 24, the temperature of the heating chamber 18 is higher than the external environment temperature, and the size of the transmission tube opening will affect the internal temperature of the heating chamber 18. The larger the opening, the stronger the flowability to the external environment, resulting in a lower temperature inside the heating chamber 18, which will cause the heating temperature of the airtightness detector shell to change, and ultimately make the test result convincing. In the process of testing the airtightness detector shell, the airtightness detector shell is likely to bulge. There are two reasons for the bulge. One is that the airtightness detector shell is deformed as a whole, and the other is that the protective film on the surface of the airtightness detector shell is deformed due to heating. When the airtightness detector shell bulges, the contact plate 23 drives the moving cylinder 17 to move upward, and the moving cylinder 17 drives the contact block 832 to move upward through the connecting spring 834. The contact block 832 and the pressure plate 833 are against each other. As the extension rod 810 keeps moving up and down, the extension rod 810 drives the pressure plate 833 to move downward, and the pressure plate 833 drives the contact plate 23 to move downward, thereby striking the protrusion of the airtightness detector housing. If the protective film is deformed, continuous striking will puncture the protective film, the protrusion will disappear, and the contact plate 23 as a whole will return to its original position relative to the fixed tube 10. At this time, the value of the corresponding pressure sensor 4 will change. If the protective film is not deformed, continuous striking will not cause the contact plate 23 as a whole to return to its original position relative to the fixed tube 10, and the value of the corresponding pressure sensor 4 will not change, thereby reminding the corresponding staff.
