Description

Technical Field

[0001] This invention relates to the technical field of testing equipment, specifically to a non-destructive testing device for sealed containers and its usage method. Background Technology

[0002] As people's demand for airtight storage continues to increase, the production efficiency and sealing effect requirements of various cup containers used for airtight storage are also increasing. Cup-type airtight containers achieve a sealing effect after the bottle mouth is tightened through a threaded structure that fits the cup body and the bottle mouth. However, existing production lines for cup-type airtight containers lack rapid testing equipment, which means that these containers can only be tested by sampling from each batch. The sealing effect of these containers consists of two parts: the integrity of the cup body and the threaded connection of the bottle mouth. Usually, only the presence of defects in the cup body can be detected, and it is not possible to test the sealing effect of both parts at the same time. As a result, some products have leakage problems in the seal between the lid and the cup body during use after leaving the factory. Furthermore, due to the limited testing methods, the production line cannot receive timely feedback and adjustments, resulting in a low yield rate of cup and bottle-type airtight containers in the market.

[0014] In a further technical solution, the testing base is provided with a main control unit, which is connected to and controls a pressure display module, a data control module, and a button adjustment module. An air pump assembly is embedded inside the testing base, and the air pump assembly is connected to a corresponding air pressure transmission and air pressure transmission component through an air pipe.

[0015] The present invention also provides a method of using a non-destructive testing device for sealed containers, comprising:

[0016] S1. Manufacturing test parts: Take an original sealing cap of a series of sealed containers to be tested and process it to make test parts. Drill a hole in the center of the sealing cap to form a test mounting hole.

[0017] S2. Assembly: Insert the embedded docking plate end into the detection mounting hole, and place the sealing top plate end on the top outer wall of the detection sealing cover. The assembly is achieved by using the threaded docking protrusion and the threaded docking groove. The detection sealing cover and the separation detection mechanism assembly are fixedly installed in the corresponding position of the detection transmission mechanism. The corresponding air pump assembly is connected to the corresponding detection telescopic rod, judgment telescopic rod and detection connecting pipe with the guide tube.

[0018] S3. Device positioning setting: Place the assembled device on the side of the production conveyor belt of this series of sealed containers, and position its separation detection mechanism and clamping processing mechanism at a suitable height on the corresponding sealing container transmission horizontal plane of the conveyor belt.

[0019] S4. Sampling inspection during production and transfer: In the production and transfer process of this series of sealed containers, the air pump assembly is started intermittently at regular intervals. First, the judgment telescopic rod slides down, and the sleeve ring is placed on the outside of the corresponding sealed container cup. At the same time, the electromagnet is started, which pushes the permanent magnet piston plate to slide and push the air pressure in the air-pushing linkage chamber into the clamping ring airbag, so that the clamping ring airbag forms a clamping and fixing effect on the outer wall of the cup. Then, the judgment shifting motor is started, which drives the clamping and processing mechanism and the sampled sealed container to deflect towards the inspection placement platform and place it in the inspection position.

[0020] S5. Sealed Container Inspection: The detection telescopic rod slides the detection function seat downwards, aligning the detection sealing cover with the mouth of the sealed container. The rotating motor then rotates the detection sealing cover, securing it firmly to the sealed container. The detection air pump assembly inputs air pressure through the detection connecting pipe into the connecting air passage, simultaneously outputting air pressure into the sealed container and to the side of the separating detection seat. During this process, some air pressure passes through the linkage air passage into the sealing annular airbag, causing it to expand. This, combined with the telescopic rubber ring, separates the mouth of the sealed container from the container storage cavity. The air pressure output effect, along with the air pressure valve orifice, applies a specified air pressure to both the mouth of the container and the container storage cavity simultaneously. The main detection module remains running, using two sets of air pressure sensor probes to detect the internal air pressure.

[0021] S6. Detection and Judgment Processing: The air pressure sensor probe on the side of the separation detection seat realizes stable air pressure detection at the cup opening, while the air pressure sensor probe at the lower end of the functional partition plate realizes stable air pressure detection inside the container storage cavity. When the pressure sensing values ​​of both air pressure sensor probes are stable and within the set threshold, the detection is qualified. The qualified sealed container is returned to the conveyor belt through structural reset. If the pressure sensing value of any one of the air pressure sensor probes changes, a sealing problem occurs. The information is recorded and transmitted to the main control unit inside the detection machine base. After structural reset, the unqualified sealed container is released and left in the detection placement table for processing.

[0022] The beneficial effects of this invention are:

[0023] The present invention discloses a non-destructive testing device for sealed containers, which is equipped with a rapid sampling inspection function. By setting it on the side of the production line conveyor belt, and through the detection and judgment transmission structure, it can realize the function of automatic sampling inspection at regular intervals during the production and conveying of sealed containers. By cooperating with the detection and judgment transmission structure and the data processing and recording module of the main control unit in the detection placement table and the detection machine base, qualified products can be automatically returned to the production line for subsequent processes, while unqualified products can be placed in the detection placement table and the data can be recorded. This allows the inspection personnel to handle and report production problems in a timely manner, enabling timely detection and adjustment of corresponding production process problems, thereby improving the yield rate.

[0024] The present invention discloses a non-destructive testing device for sealed containers, which is equipped with a separate synchronous inspection function structure. By using only one end cap of the series of sealed containers to make a test part, the non-destructive sampling inspection function of the series of sealed containers can be realized. At the same time, the test part made from the original cap has higher sealing test reproducibility and reliability. During the test, the separation test mechanism can separate the cup mouth of the sealed container to be tested from the sealed storage cavity of the cup body and perform pressure testing. Thus, when a defective product is found, the recorded data can quickly determine whether there are cracks or holes in the cup body or problems with the threads or rubber gasket sealing process between the cup mouth and the sealed end cap, thereby realizing rapid feedback and adjustment of the production process.

[0043] A method of using a non-destructive testing device for sealed containers includes:

[0044] S1. Manufacturing test parts: Take an original sealing cap of a series of sealed containers to be tested and process it to make test parts. Drill a hole in the center of the sealing cap to form a test mounting hole 36.

[0045] S2. Assembly: Insert the end of the embedded docking plate 41 into the detection mounting hole 36, and place the end of the sealing top plate 40 on the top outer wall of the detection sealing cover 32. The assembly is achieved by the threaded docking protrusion 57 and the threaded docking groove 56. The assembly of the detection sealing cover 32 and the separation detection mechanism 35 is fixedly installed in the corresponding position of the detection transmission mechanism. The corresponding air pump assembly is connected to the corresponding detection telescopic rod 27, the judgment telescopic rod 22 and the detection connecting pipe 39 through the guide tube.

[0046] S3. Device positioning setting: Place the assembled device on the side of the production conveyor belt of this series of sealed containers, and position the separation detection mechanism 35 and the clamping processing mechanism 25 at a suitable height on the corresponding horizontal plane of the conveyor belt for the sealed container.

[0047] S4. Sampling inspection during production and transfer: In the production and transfer process of this series of sealed containers, the air pump assembly is started intermittently at regular intervals. First, the judgment telescopic rod 22 is slid down to place the sleeve ring part 61 on the outside of the corresponding sealed container cup. At the same time, the electromagnet 66 is started, which pushes the permanent magnet piston plate 67 to slide and push the air pressure in the air-pushing linkage chamber 64 into the clamping ring air bag 62. This makes the clamping ring air bag 62 clamp and fix the outer wall of the cup. Then, the judgment shifting motor 24 is started to drive the clamping processing mechanism 25 and the sampled sealed container to be deflected towards the inspection placement table 34 and placed in the inspection position.

[0048] S5. Sealed Container Inspection: The detection telescopic rod 27 drives the detection function seat 29 to slide downward, aligning the detection sealing cover 32 with the mouth of the sealed container. The rotary motor 30 is then activated to rotate the detection sealing cover 32, achieving a secure installation between the detection sealing cover 32 and the sealed container. The detection air pump assembly inputs air pressure through the detection connecting pipe 39 into the connecting air passage 47, simultaneously outputting air pressure into the sealed container and to the separating detection seat 44. During this process, some air pressure passes through the linkage air passage 50 into the sealing annular airbag 53, causing the sealing annular airbag 53 to expand. Combined with the telescopic rubber ring 54, this separates the mouth of the sealed container from the container storage cavity. The air pressure output effect, along with the air pressure valve orifice 48, applies a specified air pressure to both the mouth of the container and the container storage cavity simultaneously. The main detection module 46 remains activated, using two sets of air pressure sensor probes 45 to detect the internal air pressure.

[0049] S6. Detection and Judgment Processing: The air pressure sensor probe 45 on the side of the separation detection seat 44 realizes stable detection of air pressure at the mouth of the cup, while the air pressure sensor probe 45 at the lower part of the functional partition plate 51 realizes stable detection of air pressure in the container storage cavity. When the pressure sensing values ​​of both air pressure sensor probes 45 are stable and within the set threshold, the detection is qualified. The qualified sealed container is returned to the conveyor belt through structural reset. If the pressure sensing value of any one of the air pressure sensor probes 45 changes, a sealing problem occurs. The data is recorded and transmitted to the main control body in the detection machine base 11. After structural reset, the unqualified sealed container is released and left in the detection placement table 34 for processing.

[0050] The present invention provides a non-destructive testing device for sealed containers, which is equipped with a rapid sampling inspection function. By setting it on the conveyor belt side of the production line, and through the detection and judgment transmission structure, it can realize the automatic sampling inspection function periodically during the production and conveying of sealed containers. In conjunction with the detection and judgment transmission structure and the data processing and recording module of the main control unit in the detection placement table 34 and the detection base 11, it can realize that qualified products can be automatically returned to the production line for subsequent processes, while unqualified products can be placed in the detection placement table 34 and the data can be recorded, which can facilitate the timely and rapid handling and feedback of production problems by inspection personnel. It can also realize the timely detection and adjustment of corresponding production process problems, thereby improving the yield rate.

[0051] The present invention provides a non-destructive testing device for sealed containers, which is equipped with a separate synchronous inspection function structure. By taking only one end cap of the series of sealed containers to make a test part, the non-destructive sampling inspection function of the series of sealed containers can be realized. At the same time, the test part made from the original cap has higher sealing test reproducibility and reliability. During the test, the separation test mechanism 35 can separate the cup mouth of the sealed container to be tested from the sealed storage cavity of the cup body and perform pressure test. Thus, when a defective product is found, the recorded data can quickly determine whether there are cracks or holes in the cup body or problems with the threads or rubber gasket sealing process between the cup mouth and the sealed end cap, thereby realizing rapid feedback and production process adjustment.

[0052] The above embodiments are only for illustrating the technical concept and features of the present invention, and are intended to enable those skilled in the art to understand and implement the present invention. They should not be construed as limiting the scope of protection of the present invention. All equivalent changes or modifications made in accordance with the spirit and essence of the present invention should be covered within the scope of protection of the present invention.

8. A method of using a non-destructive testing device for sealed containers, characterized in that, The non-destructive testing device for a sealed container according to claim 7 includes: S1. Manufacturing test parts: Take an original sealing cap of a series of sealed containers to be tested and process it to make test parts. Drill a hole in the center of the sealing cap to form a test mounting hole. S2. Assembly: Insert the embedded docking plate end into the detection mounting hole, and place the sealing top plate end on the top outer wall of the detection sealing cover. The assembly is achieved by using the threaded docking protrusion and the threaded docking groove. The detection sealing cover and the separation detection mechanism assembly are fixedly installed in the corresponding position of the detection transmission mechanism. The corresponding air pump assembly is connected to the corresponding detection telescopic rod, judgment telescopic rod and detection connecting pipe with the guide tube. S3. Device positioning setting: Place the assembled device on the side of the production conveyor belt of this series of sealed containers, and position its separation detection mechanism and clamping processing mechanism at a suitable height on the corresponding sealing container transmission horizontal plane of the conveyor belt. S4. Sampling inspection during production and transfer: In the production and transfer process of this series of sealed containers, the air pump assembly is started intermittently at regular intervals. First, the judgment telescopic rod slides down, and the sleeve ring is placed on the outside of the corresponding sealed container cup. At the same time, the electromagnet is started, which pushes the permanent magnet piston plate to slide and push the air pressure in the air-pushing linkage chamber into the clamping ring airbag, so that the clamping ring airbag forms a clamping and fixing effect on the outer wall of the cup. Then, the judgment shifting motor is started, which drives the clamping and processing mechanism and the sampled sealed container to deflect towards the inspection placement platform and place it in the inspection position. S5. Sealed Container Inspection: The detection telescopic rod slides the detection function seat downwards, aligning the detection sealing cover with the mouth of the sealed container. The rotating motor then rotates the detection sealing cover, securing it firmly to the sealed container. The detection air pump assembly inputs air pressure through the detection connecting pipe into the connecting air passage, simultaneously outputting air pressure into the sealed container and to the side of the separating detection seat. During this process, some air pressure passes through the linkage air passage into the sealing annular airbag, causing it to expand. This, combined with the telescopic rubber ring, separates the mouth of the sealed container from the container storage cavity. The air pressure output effect, along with the air pressure valve orifice, applies a specified air pressure to both the mouth of the container and the container storage cavity simultaneously. The main detection module remains running, using two sets of air pressure sensor probes to detect the internal air pressure. S6. Detection and Judgment Processing: The air pressure sensor probe on the side of the separation detection seat realizes stable air pressure detection at the cup opening, while the air pressure sensor probe at the lower end of the functional partition plate realizes stable air pressure detection inside the container storage cavity. When the pressure sensing values ​​of both air pressure sensor probes are stable and within the set threshold, the detection is qualified. The qualified sealed container is returned to the conveyor belt through structural reset. If the pressure sensing value of any one of the air pressure sensor probes changes, a sealing problem occurs. The information is recorded and transmitted to the main control unit inside the detection machine base. After structural reset, the unqualified sealed container is released and left in the detection placement table for processing.
