Description

Technical Field

[0001] This invention belongs to the field of testing equipment, and more specifically, relates to a latex glove sterility testing device and testing method. Background Technology

[0002] Latex gloves are disposable protective gear made primarily of natural latex. They possess excellent elasticity, fit, and protective properties, and are widely used in medical examinations, laboratory operations, and cleaning protection. Inflation testing is a common quality inspection method for latex gloves, primarily used to check for tiny leaks. During the procedure, the glove's opening is connected to an inflation column and sealed. Then, a suitable amount of air is injected into the glove through the column to inflate it, and it is observed whether the glove can maintain its inflated state for a certain period. If the glove leaks air rapidly after inflation or fails to inflate, it indicates potential damage or pinholes, making it a substandard product. This method effectively detects minute defects that are difficult to see with the naked eye, ensuring the integrity and safety of the gloves.

[0003] Current methods for testing the inflation of latex gloves typically involve manually placing the glove's opening over an inflation column, then sealing the opening by hand before testing. This entire process requires manual intervention, resulting in high labor costs and low efficiency. Furthermore, manual testing increases the risk of bacterial contamination of the latex gloves, compromising their safety. Summary of the Invention

[0004] In view of the problems in the related technologies, the present invention proposes a latex glove sterility testing device and testing method to overcome the above-mentioned technical problems existing in the existing related technologies.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: This invention relates to a sterility testing device for latex gloves, comprising a testing cabinet equipped with multiple airtightness testing units. Each airtightness testing unit includes a conveying fixture, a sealing mechanism, and an inflation testing mechanism. The conveying fixture transports the latex gloves back and forth between the loading / unloading station and the inflation testing station. The inflation testing mechanism connects to the wearing opening of the latex gloves when they are transported to the inflation testing station. Simultaneously, the sealing mechanism clamps and seals the wearing opening of the latex gloves. The inflation testing mechanism also inflates and maintains pressure inside the latex gloves after sealing, and detects the air pressure inside the latex gloves.

[0006] Furthermore, the conveying fixture includes a guide rail and a hydraulic telescopic shaft. Both the guide rail and the hydraulic telescopic shaft are fixedly installed on the testing cabinet. A fixture seat for placing latex gloves is slidably installed on the guide rail. The telescopic end of the hydraulic telescopic shaft is fixedly connected to the fixture seat, and the hydraulic telescopic shaft can drive the fixture seat to move back and forth between the loading / unloading station and the inflation testing station along the guide rail.

[0007] Furthermore, the inflation testing mechanism includes an inflation nozzle and an inflation testing unit. The inflation nozzle is fixedly installed above the fixture base, and the inflation testing unit is fixedly installed at the inflation testing station position on the testing cabinet. When the inflation nozzle moves with the fixture base to the inflation testing station, the inflation nozzle can be sealed and connected with the inflation testing unit.

[0008] Furthermore, the inflation detection unit includes an inflation conduit, which is fixedly installed on the detection cabinet. One end of the inflation conduit is connected to the air storage tank through a solenoid valve, and the other end of the inflation conduit is provided with a plug that can be sealed and inserted into the air inlet of the inflation nozzle. A pressure gauge is also connected and installed on the inflation conduit.

[0009] Furthermore, the sealing mechanism includes an upper clamping sealing component and a lower clamping sealing component. The lower clamping sealing component is disposed on the fixture seat and located below the inflation nozzle. The upper clamping sealing component is disposed above the inflation testing station on the testing cabinet. When the fixture seat moves the latex glove to the inflation testing station, the upper clamping sealing component and the lower clamping sealing component can move towards each other and close together, so that the upper clamping sealing component and the lower clamping sealing component cooperate to clamp and seal the wearing opening of the latex glove. The clamping ends of the upper clamping sealing component and the lower clamping sealing component are provided with grooves corresponding to the inflation nozzle.

[0010] Furthermore, the upper clamping sealing assembly includes a crossbeam, which is fixedly installed on the upper end of the testing cabinet. A lifting hydraulic cylinder is fixedly installed on the crossbeam, and the telescopic end of the lifting hydraulic cylinder extends downward to the bottom of the crossbeam. A lifting plate is fixedly installed at the bottom of the telescopic end of the lifting hydraulic cylinder, and an upper sealing clamping block is fixedly installed on the bottom surface of the lifting plate.

[0011] Furthermore, the lower clamping sealing assembly includes a lower sealing clamp and a lifting drive unit. The lower sealing clamp is slidably mounted on the top surface of the fixture seat via a sliding groove, and the lower sealing clamp is located below the inflation nozzle. When the lifting plate moves the upper sealing clamp downward, the lifting drive unit can drive the lower sealing clamp to move upward at the same time, so that the upper sealing clamp and the lower sealing clamp cooperate to clamp and seal the wearing opening of the latex glove.

[0012] Furthermore, the lifting drive unit includes a stop block, a lifting slider, and a translating wedge block. The stop block is fixedly installed on the bottom surface of the lifting plate. The lifting slider is slidably inserted into the top surface of the fixture seat. A lifting wedge block is fixedly installed at the bottom end of the lifting slider. The translating wedge block is slidably installed inside the fixture seat. Guide slopes are provided at both ends of the top surface of the translating wedge block. The guide slope at one end of the translating wedge block slides and abuts against the guide slope at the bottom end of the lifting wedge block. The guide slope at the other end of the translating wedge block slides and abuts against the guide slope at the bottom surface of the lower sealing clamp block.

[0013] Furthermore, a base is fixedly installed at the bottom end of the side of the lower sealing clamp block, and a return spring is installed abutting against the top surface of the base.

[0014] A method for aseptic testing of latex gloves, the specific steps of which are as follows: The latex gloves are held and placed on the conveyor fixture by a robotic arm; The conveying fixture transports the latex gloves from the loading and unloading station to the inflation testing station, and the inflation testing mechanism connects with the wearing opening of the latex gloves when the latex gloves are transported to the inflation testing station. The latex glove's opening is then clamped and sealed by a sealing mechanism. Finally, the latex glove is inflated by an inflation testing mechanism to make it expand. The air pressure inside the latex glove is then tested. If the air pressure remains unchanged, it indicates that the latex glove has good airtightness. If the air pressure decreases, it indicates that the latex glove is leaking air.

[0015] The present invention has the following beneficial effects: In this invention, during the inflation test of latex gloves, a robotic arm clamps the latex gloves and places them on a conveying fixture. The conveying fixture transports the latex gloves from the loading / unloading station to the inflation test station. The inflation test mechanism connects to the glove's wearing opening when the glove arrives at the inflation test station, and a sealing mechanism clamps and seals the wearing opening. Finally, the inflation test mechanism inflates the latex gloves, causing them to expand. The air pressure inside the glove is then measured. If the air pressure remains constant, the latex glove has good airtightness; if the air pressure decreases, the glove is leaking. Thus, the coordination of the conveying fixture, sealing mechanism, and inflation test mechanism achieves automated inflation testing of latex gloves. This reduces labor costs and improves testing efficiency. Furthermore, reduced human intervention makes it less likely for the latex gloves to become contaminated with bacteria, facilitating testing in a sterile environment.

[0016] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0020] The technical solutions of the embodiments of the invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the invention, and not all embodiments. Based on the embodiments of the invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the invention.

[0021] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the invention.

[0022] Example 1 Please see Figures 1-10 As shown, the present invention is a latex glove sterility testing device, including a testing cabinet 1. The testing cabinet 1 is equipped with multiple airtightness testing units. Each airtightness testing unit includes a conveying fixture 2, a sealing mechanism 3, and an inflation testing mechanism 4. The conveying fixture 2 can transport the latex gloves back and forth between the loading / unloading station and the inflation testing station. The inflation testing mechanism 4 can connect with the wearing opening of the latex glove when the latex glove is transported to the inflation testing station. At the same time, the sealing mechanism 3 clamps and seals the wearing opening of the latex glove. The inflation testing mechanism 4 can also inflate and maintain pressure inside the latex glove after it is sealed, and detect the air pressure inside the latex glove.

[0023] When performing inflation testing on latex gloves, a robotic arm clamps and places the latex gloves onto a conveying fixture 2. The conveying fixture 2 then transports the latex gloves from the loading / unloading station to the inflation testing station. The inflation testing mechanism 4 connects to the wearing opening of the latex gloves when they arrive at the inflation testing station. The wearing opening of the latex gloves is then clamped and sealed by a sealing mechanism 3. Finally, the inflation testing mechanism 4 inflates the latex gloves to make them expand. The air pressure inside the latex gloves is then tested. If the air pressure remains constant, it indicates that the latex gloves are airtight. If the air pressure decreases, it indicates that the latex gloves are leaking. Thus, the cooperation of the conveying fixture 2, the sealing mechanism 3, and the inflation testing mechanism 4 achieves automated inflation testing of latex gloves. This reduces the labor costs of latex glove testing, improves testing efficiency, and reduces the risk of bacterial contamination of the latex gloves due to reduced human intervention, thereby facilitating testing of latex gloves in a sterile environment.

[0024] Specifically, the conveying fixture 2 includes a guide rail 22 and a hydraulic telescopic shaft 23. Both the guide rail 22 and the hydraulic telescopic shaft 23 are fixedly installed on the testing cabinet 1. A fixture seat 21 for placing latex gloves is slidably installed on the guide rail 22. The telescopic end of the hydraulic telescopic shaft 23 is fixedly connected to the fixture seat 21, and the hydraulic telescopic shaft 23 can drive the fixture seat 21 to move back and forth along the guide rail 22 between the loading / unloading station and the inflation testing station, so as to drive the latex gloves to move back and forth between the loading / unloading station and the inflation testing station for inflation testing and loading / unloading. The loading / unloading station is located in an open space on the testing cabinet 1 with no obstruction above it, so as to facilitate loading / unloading of latex gloves manually or by a robotic arm.

[0025] Specifically, the inflation testing mechanism 4 includes an inflation nozzle 41 and an inflation testing unit. The inflation nozzle 41 is fixedly installed above the fixture base 21, and the inflation testing unit is fixedly installed at the inflation testing station position on the testing cabinet 1. When the inflation nozzle 41 moves with the fixture base 21 to the inflation testing station, the inflation nozzle 41 can seal and connect with the inflation testing unit. The inflation testing unit includes an inflation conduit 42, which is fixedly installed on the testing cabinet 1. One end of the inflation conduit 42 is connected to the air storage tank through a solenoid valve, and the other end of the inflation conduit 42 is provided with a connector that can seal and connect with the air inlet end of the inflation nozzle 41. A pressure gauge 43 is also connected and installed on the inflation conduit 42.

[0026] When the latex glove is placed on the fixture seat 21 at the loading and unloading station, the wearing opening of the latex glove is put over the inflation nozzle 41, so that the inflation nozzle 41 can extend into the inside of the latex glove. Then, when the inflation nozzle 41 moves with the fixture seat 21 to the inflation test station, the inflation nozzle 41 is sealed and connected to the plug of the inflation conduit 42. After the sealing mechanism 3 clamps and seals the wearing opening of the latex glove (at this time, the inflation nozzle 41 is sealed and plugged into the latex glove), the solenoid valve on the inflation conduit 42 is opened, so that the air tank inflates into the latex glove through the inflation conduit 42 and the inflation nozzle 41, thereby inflating the latex glove. Then the solenoid valve is closed to maintain the pressure inside the latex glove. At the same time, the air pressure inside the latex glove is detected by the pressure gauge 43. If the air pressure remains unchanged, it indicates that the latex glove has good air tightness. If the air pressure decreases, it indicates that the latex glove is leaking.

[0027] Specifically, the sealing mechanism 3 includes an upper clamping sealing component and a lower clamping sealing component. The lower clamping sealing component is mounted on the fixture base 21 and located below the inflation nozzle 41. The upper clamping sealing component is positioned above the inflation testing station on the testing cabinet 1. When the fixture base 21 moves the latex glove to the inflation testing station, the upper and lower clamping sealing components can move towards each other and close together, so that the upper and lower clamping sealing components cooperate to clamp and seal the wearing opening of the latex glove. The clamping end of the sealing component is provided with a groove corresponding to the inflation nozzle 41. When the upper clamping sealing component and the lower clamping sealing component are engaged, the upper clamping sealing component and the lower clamping sealing component clamp and seal the wearing opening of the latex glove. At the same time, the upper clamping sealing component and the lower clamping sealing component clamp and seal the latex glove and the inflation nozzle 41 through the groove corresponding to the inflation nozzle 41, thereby completely sealing the wearing opening of the latex glove, leaving only the inflation nozzle 41 as the inflation channel, so as to facilitate subsequent inflation testing of the latex glove.

[0028] Specifically, the upper clamping sealing assembly includes a crossbeam 31, which is fixedly installed on the upper end of the testing cabinet 1. A lifting hydraulic cylinder 32 is fixedly installed on the crossbeam 31. The telescopic end of the lifting hydraulic cylinder 32 extends downward to the bottom of the crossbeam 31, and a lifting plate 33 is fixedly installed at the bottom of the telescopic end of the lifting hydraulic cylinder 32. An upper sealing clamping block 34 is fixedly installed on the bottom surface of the lifting plate 33. The lower clamping sealing assembly includes a lower sealing clamp 35 and a lifting drive unit. The lower sealing clamp 35 is mounted on the top surface of the fixture seat 21 via a sliding groove, and the lower sealing clamp 35 is located below the inflation nozzle 41. When the lifting plate 33 moves the upper sealing clamp 34 downward, the lifting drive unit can drive the lower sealing clamp 35 to move upward at the same time, so that the upper sealing clamp 34 and the lower sealing clamp 35 cooperate to clamp and seal the wearing opening of the latex glove.

[0029] The lower sealing clamp 35 is initially hidden in the groove on the top surface of the fixture 21, so that there is enough space below the inflation nozzle 41 to facilitate the wearing opening of the latex glove onto the inflation nozzle 41. Then, when the fixture 21 and the latex glove move to the inflation test station (at this time, the lower sealing clamp 35 is directly below the upper sealing clamp 34), the lifting hydraulic cylinder 32 drives the lifting plate 33 and the upper sealing clamp 34 to move downward, while the lifting drive unit drives the lower sealing clamp 35 to move upward, so that the upper sealing clamp 34 and the lower sealing clamp 35 gradually move and close, and clamp and seal the wearing opening of the latex glove at the height of the inflation nozzle 41.

[0030] Specifically, the lifting drive unit includes a stop block 36, a lifting slider 37, and a translating wedge block 39. The stop block 36 is fixedly installed on the bottom surface of the lifting plate 33. The lifting slider 37 is slidably inserted into the top surface of the fixture seat 21. A lifting wedge block 38 is fixedly installed at the bottom end of the lifting slider 37. The translating wedge block 39 is slidably installed inside the fixture seat 21. Guide slopes are provided at both ends of the top surface of the translating wedge block 39. The guide slope at one end of the translating wedge block 39 slides and abuts against the guide slope at the bottom end of the lifting wedge block 38. The guide slope at the other end of the translating wedge block 39 slides and abuts against the guide slope at the bottom surface of the lower sealing clamp block 35. A base 310 is fixedly installed at the bottom end of the side of the lower sealing clamp block 35. A return spring 311 is abutted against the top surface of the base 310.

[0031] When the fixture seat 21 moves to the inflation test station, the lifting slider 37 is located directly below the abutment block 36. Then, when the lifting plate 33 descends, it drives the abutment block 36 to move downwards simultaneously, causing the abutment block 36 to abut the lifting slider 37 downwards. At this time, the lifting slider 37 drives the lower lifting wedge block 38 to slide downwards. As the lifting wedge block 38 slides downwards, it moves the translation wedge block 39 to abut the lower sealing clamp block 35 through the guide slope, so that the translation wedge block 39 gradually pushes the lower sealing clamp block 35 upwards through the guide slope. This causes the lower sealing clamp 35 to gradually move upward and cooperate with the upper sealing clamp 34 to clamp and seal the wearing opening of the latex glove. When the inflation test of the latex glove is completed, when the lifting plate 33 drives the upper sealing clamp 34 to move upward and reset, the lifting plate 33 drives the abutment block 36 to move upward and reset simultaneously to release the pressure on the lifting slider 37. At this time, the lower sealing clamp 35 slides downward and resets under the reset force of the reset spring 311, so that the lower sealing clamp 35 moves downward again and hides in the groove on the top surface of the fixture seat 21, which facilitates the subsequent placement and testing of the latex glove.

[0032] Example 2 This embodiment discloses a method for aseptic testing of latex gloves, the specific steps of which are as follows: The latex gloves are held and placed on the conveyor fixture 2 by a robotic arm; The conveying fixture 2 conveys the latex gloves from the loading and unloading station to the inflation detection station, and the inflation detection mechanism 4 connects with the wearing opening of the latex gloves when the latex gloves are conveyed to the inflation detection station. The sealing mechanism 3 then clamps and seals the opening of the latex glove. Finally, the latex glove is inflated by the inflation testing mechanism 4 to make it expand. The air pressure inside the latex glove is then tested. If the air pressure remains unchanged, it indicates that the latex glove has good air tightness. If the air pressure decreases, it indicates that the latex glove is leaking air.
