[0001] The utility model relates to the field of thermos cup production, in particular to an air tightness detection device for the production of stainless steel thermos cups. Background Art

[0002] In the manufacturing process of stainless steel thermos cups, the evaluation of air tightness is a key step in quality control. After the stainless steel inner liner and the circular bottom sheet are welded into the thermos cup inner liner assembly, air tightness detection is required. Traditionally, this evaluation relies on the water immersion test method, that is, the thermos cup inner liner assembly is placed in water, and whether there are bubbles emerging is observed to judge whether its sealing performance meets the standard. However, this method exposes many limitations in practice, such as high resource consumption, cumbersome operation, environmental pollution risk, and limited scope of application. In view of the above limitations, there is an urgent need in the market for a more efficient, environmentally friendly, accurate and easy-to-operate air tightness detection device for stainless steel thermos cups to replace the traditional water immersion test method, so as to improve production efficiency and product quality, and reduce production costs and environmental pollution risks.

[0023] This embodiment mainly describes the structure of the airtightness detection device as follows:

[0024] An airtightness detection device for the production of stainless steel vacuum cups, as Figures 1-4As shown in the figure, it includes a workbench 1, a vacuum pump 2, a mounting plate 3, a conduit 4, a vacuum sensor 5, and a detection seat 6.

The vacuum pump 2 is fixedly connected to the mounting plate 3 by bolts. The output end of the vacuum pump 2 is connected to the lower end of the conduit 4. The upper end of the conduit 4 is fixedly connected to the detection seat 6. The detection seat 6 is made of hard metal. The vacuum pump 2 pumps out the air inside the thermos cup inner liner assembly to be detected through the conduit 4. A vacuum sensor 5 is installed at the upper end of the conduit 4. The vacuum sensor 5 is used to detect the pressure retention ability of the thermos cup inner liner assembly after being evacuated. And the height of the vacuum sensor 5 is lower than that of the detection seat 6. The feedback assembly for feeding back the detection result is fixedly connected to the workbench 1. The feedback assembly includes a feedback housing 7, a warning light 8, and a PLC module 9. The feedback housing 7 is fixedly connected to the workbench 1. The warning light 8 is installed on the top of the feedback housing 7. The warning light 8 lights up in a striking red color. The PLC module 9 is fixedly connected to the right side of the feedback housing 7. The PLC module 9 is electrically connected to the vacuum sensor 5. If the thermos cup inner liner assembly to be detected can retain pressure, its airtightness is good and it is a good product. The PLC module 9 will not control the warning light 8 to light up. If the thermos cup inner liner assembly to be detected cannot retain pressure, its airtightness is poor and it is a defective product. The vacuum sensor 5 will control the PLC module 9 to make the warning light 8 light up, reminding the operator that this detected thermos cup inner liner assembly is a defective product. It also includes a mounting seat 10, a positioning ring 11, and a wing nut 12. The mounting seat 10 is fixedly connected to the workbench 1. A groove is provided in the mounting seat 10. The positioning ring 11 is slidably connected in the groove. The left end of the positioning ring 11 is provided with threads. The left side of the positioning ring 11 is threadedly connected to the wing nut 12. The positioning ring 11 can change the fixed height in the groove of the mounting seat 10 according to the user's needs and is fixed with the wing nut 12, guiding the thermos cup inner liner assembly to be detected well and preventing the thermos cup inner liner assembly from deviating from the detection seat 6. It also includes a rotating seat 13 and a protective cover 14. The rotating seat 13 is fixedly connected to the workbench 1. The protective cover 14 is rotatably connected to the rotating seat 13. The protective cover 14 is used to protect the detection seat 6 and the conduit 4, improving the service life of the device. The width of the protective cover 14 is greater than the maximum diameter of the detection seat 6. It also includes a magnet 15. Magnets 15 are fixedly connected to both the protective cover 14 and the workbench 1. The magnet 15 is used to fix the protective cover 14 to the workbench 1 during the use of the device. It also includes a protective pad 16. The protective pad 16 is fixedly connected to the detection seat 6. The protective pad 16 is concentric with the conduit 4. And the outer diameter of the protective pad 16 is smaller than the outer diameter of the detection seat, and the inner diameter of the protective pad 16 is larger than the outer diameter of the conduit 4. The protective pad 16 is used to prevent the cup mouth of the thermos cup inner liner assembly from being scratched during the detection process. It also includes a collection box 17. The collection box 17 is fixedly connected to the right side of the workbench 1. The collection box 17 is used to temporarily store defective products to prevent defective products from being mixed into good products. It also includes a bundling plate 18,A bundling plate 18 is fixedly connected to the lower part of the workbench 1. The bundling plate 18 is used for bundling and arranging the conduit 4 to prevent the conduit 4 from being wound around the remaining lines, resulting in damage to the equipment.

[0025] Before the device is put into use, the operator needs to first rotate the protective cover 14 by 180 degrees and make the magnet 15 on the protective cover 14 fit and adsorb with the magnet 15 on the workbench 1 to prevent the protective cover 14 from shaking during the test. Then, the operator needs to turn the wing nut 12 counterclockwise and adjust the height of the positioning ring 11 according to the height of this batch of stainless steel vacuum cup inner liner assemblies. After the adjustment is completed, turn the wing nut 12 clockwise to firmly fix the positioning ring 11 on the mounting seat 10. At this time, place the cup mouth of the vacuum cup inner liner assembly to be detected on the detection seat 6 with the cup mouth facing downwards, and align the cup mouth with the conduit 4 port of the detection seat 6. When the operator places the stainless steel vacuum cup inner liner assembly, after passing through the positioning ring 11, the positioning ring 11 will play a role in positioning and guiding the stainless steel vacuum cup inner liner assembly, achieving the effect of preventing the vacuum cup inner liner assembly from deviating from the detection seat 6. During the test, the protective pad 16 closely adheres to the detection seat 6. When the vacuum cup inner liner assembly is placed on the detection seat 6, the protective pad 16 can prevent the cup mouth of the vacuum cup inner liner assembly from directly contacting the hard detection seat 6, thereby avoiding abrasion or scratches on the cup mouth, which is crucial for protecting the appearance of the vacuum cup inner liner assembly and extending its service life. At this time, start the vacuum pump 2, and the vacuum pump 2 starts to extract the air inside the vacuum cup inner liner assembly through the conduit 4, gradually forming a vacuum state inside the vacuum cup inner liner assembly. At this time, the output end of the vacuum pump 2 is connected to the lower end of the conduit 4, and the upper end of the conduit 4 is closely connected to the detection seat 6 to ensure that the vacuum environment can be accurately formed. When a certain vacuum degree is reached inside the vacuum cup inner liner assembly, the vacuum pump 2 stops working. At this time, the vacuum sensor 5 starts to work to monitor the pressure-holding ability inside the vacuum cup inner liner assembly. The vacuum sensor 5 is installed at the upper end of the conduit 4 and its height is lower than that of the detection seat 6 to ensure that it can accurately sense the pressure change inside the vacuum cup inner liner assembly. If the vacuum cup inner liner assembly can maintain good sealing performance and pressure-holding ability, that is, the internal vacuum degree has no obvious change within the set time, the vacuum sensor 5 will transmit this information to the PLC module 9. After receiving the signal from the vacuum sensor 5, the PLC module 9 makes a judgment according to the preset program logic. If the vacuum cup inner liner assembly is a good product, that is, the pressure-holding ability meets the standard, the PLC module 9 does not control the warning light 8 to light up, and the test process ends. The operator can remove the vacuum cup inner liner assembly for the next step of processing. If the vacuum cup inner liner assembly is a defective product, that is, the pressure-holding ability does not meet the standard, the PLC module 9 will control the warning light 8 to light up, reminding the operator that there is a quality problem with this vacuum cup inner liner assembly and further processing or elimination is required. At the same time, the defective products can be temporarily stored in the collection box 17 to prevent confusion with the good products. After the test is completed, the operator can rotate the protective cover 14 to cover the detection seat 6 to protect components such as the detection seat 6 and the conduit 4. In addition, the conduit 4 on the bundling plate 18 can also be sorted out to prevent entanglement with other lines, ensuring the cleanliness and safety of the equipment.
