Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical machinery and equipment technology, specifically to a transmission structure for high-pressure leak detection of glass medicine bottles. Background Technology

[0002] In October 2020, the Center for Drug Evaluation of the National Medical Products Administration (NMPA) issued the "Technical Guidelines for Sealing Studies of Packaging Systems for Injectable Chemical Drugs (Trial)." These guidelines set forth clear requirements for sealing studies of injection packaging systems: sterility testing must be conducted at the beginning and end of stability studies of injections; at other time points, sealing tests of the packaging system can be used as an alternative method. Furthermore, the guidelines emphasize that in commercial production, companies must establish comprehensive sealing testing and control measures for packaging systems to ensure drug quality and patient safety.

[0003] Currently, high-voltage discharge leak detection technology is widely used in the sealing inspection of injectable packaging systems, especially in the sealing inspection of vials and ampoules. The principle of this technology is: applying a high voltage to the vial to be inspected, and determining whether the vial's sealing is up to standard by detecting differences in electrical parameters (such as current and voltage) and characterizations (such as discharge phenomena) between defective and undefective vials. This method is non-destructive and highly sensitive, effectively identifying minute sealing defects. Although high-voltage discharge leak detection technology demonstrates high reliability in sealing inspection, it still has the following limitations in practical applications:

[0004] 1. Low detection efficiency: Current high-voltage discharge leak detectors can only detect a single medicine bottle and cannot detect multiple medicine bottles at the same time, resulting in low detection efficiency and making it difficult to meet the needs of large-scale production.

[0005] 2. Limited detection range: Current technology cannot detect all parts of the medicine bottle, but can only cover part of the bottle, which may lead to the risk of missed detections and affect the comprehensiveness and accuracy of the test results. Utility Model Content

[0006] The present invention aims to provide a transmission structure for high-pressure leak detection of glass medicine bottles, which can improve detection efficiency and avoid the risk of missed detection.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] 1) A transmission structure for high-pressure leak detection of glass medicine bottles includes a circular tray, an annular damping mechanism is provided on the upper surface of the tray with the center of the circle, a turntable is rotatably connected above the tray with the center of the circle, the turntable can rotate around its center on the upper surface of the tray, and several through holes are evenly distributed on the upper surface of the turntable along its circumferential direction, all through holes facing the damping mechanism, the through holes and the upper surface of the tray together form a groove for placing medicine bottles.

[0009] This invention employs a high-voltage discharge method to test the seal of medicine bottles, using a SPAX-HV high-voltage discharge leak detector. During the testing process, this invention is installed entirely within the high-voltage discharge detector, replacing the original medicine bottle placement structure to improve testing efficiency and comprehensiveness.

[0010] In this invention, a turntable is rotatably connected to the tray above it, and several through holes are evenly distributed along its circumference on the upper surface of the turntable. These through holes, together with the upper surface of the tray, form a groove for placing medicine bottles. When this invention is installed inside a high-voltage discharge detector, the drive device can drive the turntable to rotate. The rotation of the turntable can cause the medicine bottles placed in the groove to rotate synchronously. At the same time, the through holes can fix the position of the medicine bottles in the turntable, restricting the horizontal movement of the medicine bottles during rotation, thereby ensuring that the medicine bottles rotate under the resistance of the damping mechanism.

[0011] A damping mechanism is centrally located on the upper surface of the tray, with all through-holes facing the mechanism. During testing, the medicine bottle is placed within the groove, allowing its outer wall to directly contact the damping mechanism. As the turntable rotates, the medicine bottle rotates synchronously. Simultaneously, the damping mechanism contacts the outer wall of the bottle, creating resistance as the bottle moves with the turntable. This resistance, combined with the limiting effect of the through-holes, prevents the bottle from completely following the turntable's movement.

[0012] As the turntable rotates continuously, the medicine bottle is constantly driven by the turntable. Under the interaction of the driving force and the resistance of the damping mechanism, the bottle undergoes relative motion, causing it to rotate around its own axis. This rotation ensures that all parts of the bottle are fully exposed within the detection range of the equipment, thus improving the comprehensiveness of the detection. Furthermore, the turntable has several evenly spaced through holes, each capable of accommodating one medicine bottle. Therefore, multiple bottles can be detected simultaneously, thereby improving detection efficiency.

[0013] 2) According to the transmission structure for high-pressure leak detection of glass medicine bottles described in 1), wherein:

[0014] The damping mechanism includes a first damping ring and a second damping ring. The upper surface of the tray has a first damping groove and a second damping groove that are circularly arranged. The first damping ring is embedded in the first damping groove, and the upper surface of the first damping ring is flush with the opening of the first damping groove. The second damping ring is embedded in the second damping groove, and the upper surface of the second damping ring is flush with the opening of the second damping groove.

[0015] In this invention, when the turntable drives the medicine bottle to rotate, the outer wall of the medicine bottle contacts the first damping ring and the second damping ring. Since the first damping ring is embedded and fixed in the first damping groove, and the second damping ring is embedded and fixed in the second damping groove, it ensures that the first and second damping rings will not shift or loosen during contact with the medicine bottle, thus providing stable resistance as the medicine bottle rotates with the turntable. The resistance acting on the outer wall of the medicine bottle, combined with the limiting effect of the through hole, jointly restricts the medicine bottle from completely following the movement of the turntable. As the turntable continues to rotate, the medicine bottle is continuously subjected to the driving force of the turntable. Under the interaction of the driving force of the turntable and the resistance of the damping mechanism, the medicine bottle generates relative motion, thereby rotating around its own axis.

[0016] When the medicine bottle is placed in the groove formed by the through hole and the tray, the upper surface of the first damping ring is flush with the opening of the first damping groove, and the upper surface of the second damping ring is flush with the opening of the second damping groove. This ensures the flatness of the contact surface between the medicine bottle and the tray. Therefore, the outer wall of the medicine bottle can fully fit against the surface of the tray, thus preventing the medicine bottle from shaking or tilting due to uneven contact surfaces. At the same time, the upper surfaces of the first and second damping rings can make close contact with the outer wall of the medicine bottle, allowing the first and second damping rings to provide stable resistance to the medicine bottle and ensure the stability of the medicine bottle during its rotation.

[0017] The first and second damping rings simultaneously provide resistance to the medicine bottle, resulting in two points of resistance acting on the outer wall of the bottle. This configuration allows for a more uniform distribution of resistance on the outer wall of the bottle, preventing wobbling or displacement caused by uneven resistance and ensuring the stability of the bottle during rotation.

[0018] 3) According to the transmission structure for high-pressure leak detection of glass medicine bottles described in 1), wherein:

[0019] The through hole includes a narrow strip-shaped through hole. Several narrow strip-shaped through holes are formed around the center of the turntable on its upper surface. The narrow strip-shaped through holes are set close to the center of the turntable. Each narrow strip-shaped through hole is connected to a wide strip-shaped through hole at one end away from the center of the turntable.

[0020] In this invention, the upper surface of the turntable has several narrow strip-shaped through holes around its center. These narrow strip-shaped through holes are positioned close to the center of the turntable, and their size matches the neck of the medicine bottle to accommodate the neck. Each narrow strip-shaped through hole has a wide strip-shaped through hole connected to its end furthest from the center of the turntable. The size of the wide strip-shaped through hole matches the body of the medicine bottle to accommodate the body. The wide strip-shaped through holes connect with the narrow strip-shaped through holes, forming through holes that match the shape of the medicine bottle. When the medicine bottle is placed in the groove formed by the through holes and the upper surface of the tray, the neck of the medicine bottle fits against the inner wall of the narrow strip-shaped through hole, and the body of the medicine bottle fits against the inner wall of the wide strip-shaped through hole, thereby limiting the movement of the medicine bottle during the testing process and ensuring its stability.

[0021] As the turntable rotates, the medicine bottle moves synchronously with it. The through-hole limits the bottle's movement, preventing it from wobbling or shifting during rotation. Simultaneously, the upper surfaces of the first and second damping rings are in close contact with the outer wall of the bottle, creating resistance to its movement. The combined effect of this resistance and the limiting function of the through-hole effectively prevents the bottle from completely following the turntable's movement. Under the interaction of the turntable's driving force and the resistance from the first and second damping rings, the bottle rotates around its own axis, thus achieving comprehensive inspection.

[0022] 4) According to the transmission structure for high-pressure leak detection of glass medicine bottles described in 1), wherein:

[0023] The upper surface of the tray has a circular conductive groove with the same center. The conductive groove is located between the first damping groove and the second damping groove. A conductive ring is embedded in the conductive groove, and the upper surface of the conductive ring is flush with the opening of the conductive groove.

[0024] In this invention, as the medicine bottle rotates with the turntable, its outer wall moves relative to the first and second damping rings, generating friction. This friction leads to charge transfer, thus generating static electricity on the surface of the medicine bottle. During continuous rotation, static electricity gradually accumulates. When it accumulates to a certain level, it may trigger a discharge phenomenon, generating electric sparks, which could damage the detection equipment or cause a safety accident. To eliminate the hazards of static electricity, when this device is installed inside a high-voltage discharge detector, the conductive ring is connected to the ground wire to release static electricity from the surface of the medicine bottle.

[0025] This invention features an annular conductive groove on the upper surface of the tray, positioned between a first damping groove and a second damping groove. A conductive ring is embedded and fixed within this groove, ensuring that the conductive ring will not shift or loosen when in contact with the medicine bottle. Furthermore, the upper surface of the conductive ring is flush with the opening of the conductive groove, guaranteeing the flatness of the contact surface between the medicine bottle and the tray. This allows the outer wall of the medicine bottle to fully conform to the tray surface, preventing shaking or tilting caused by uneven contact surfaces.

[0026] When the medicine bottle is placed in the groove formed by the through hole and the tray, the side wall of the medicine bottle is in close contact with the first damping ring, the second damping ring and the conductive ring at the same time. This allows the static electricity on the surface of the medicine bottle to be released to the ground wire through the conductive ring, thereby avoiding the occurrence of discharge and ensuring the safety of the detection process.

[0027] 5) According to the transmission structure for high-pressure leak detection of glass medicine bottles described in 1), wherein:

[0028] The turntable has a downward-extending connecting rod at the center of its bottom surface. The tray has a connecting hole that matches the connecting rod. The connecting rod passes through the connecting hole and is rotatably connected to the tray. The turntable can rotate on the upper surface of the tray with the connecting rod as the center.

[0029] When this invention is installed inside a high-voltage discharge detector, the tray is fixedly installed inside the detector, and the end of the connecting rod is fixedly connected to the drive mechanism. After the drive mechanism is started, it drives the connecting rod to rotate around its axis. The rotation of the connecting rod drives the turntable to rotate synchronously. The connecting rod passes through the connecting hole and is rotatably connected to the tray, allowing the turntable to rotate on the upper surface of the tray, thereby realizing the rotation of the medicine bottle and ensuring that the outer surface of the medicine bottle can be fully inspected.

[0030] Compared with the prior art, this utility model also has the following technical effects:

[0031] In this invention, the damping mechanism provides resistance to the rotating medicine bottle, and this resistance, combined with the limiting effect of the through-hole, restricts the medicine bottle from completely following the rotation of the turntable. Under the interaction of the driving force of the turntable and the resistance of the damping mechanism, the medicine bottle rotates around its own axis. Compared with the prior art, this invention ensures that all parts of the medicine bottle are fully exposed within the detection range of the detection equipment through the rotation of the medicine bottle, thereby improving the comprehensiveness of the detection. Secondly, the turntable is provided with multiple through-holes, allowing multiple medicine bottles to be placed for detection simultaneously, significantly improving detection efficiency. In addition, by setting a conductive ring, static electricity on the surface of the medicine bottle can be released in time, avoiding the discharge phenomenon that may be caused by static electricity accumulation, and ensuring the safety of the detection process.

[0034] Figure 3 This is a schematic diagram of the structure of the tray in the high-pressure leak detection of a glass medicine bottle according to this utility model. Detailed Implementation

[0035] The following detailed description illustrates the specific implementation method:

[0036] The reference numerals in the accompanying drawings include: tray 1, turntable 2, through hole 3, first damping ring 4, second damping ring 5, first damping groove 6, second damping groove 7, narrow strip through hole 8, wide strip through hole 9, conductive ring 10, conductive groove 11, connecting rod 12, and connecting hole 13.

[0037] See the example. Figure 1 , Figure 2 and Figure 3 As shown, the transmission structure for high-pressure leak detection of glass medicine bottles in this embodiment includes a circular tray 1. A ring-shaped damping mechanism is provided on the upper surface of the tray 1 with the center of the circle. A turntable 2 is rotatably connected to the upper surface of the tray 1 with the center of the circle. The turntable 2 can rotate around its center on the upper surface of the tray 1. Six through holes 3 are evenly distributed on the upper surface of the turntable 2 along its circumferential direction. All through holes 3 face the damping mechanism. The through holes 3 and the upper surface of the tray 1 together form a groove for placing the medicine bottle.

[0038] This embodiment uses a high-voltage discharge method to test the seal of the medicine bottle, employing a SPAX-HV high-voltage discharge leak detector. During the testing process, this embodiment is installed entirely within the high-voltage discharge detector, replacing the original medicine bottle placement structure to improve testing efficiency and comprehensiveness.

[0039] In this embodiment, a turntable 2 is rotatably connected to the tray 1 above it. Several through holes 3 are evenly distributed along the circumferential direction on the upper surface of the turntable 2. These through holes 3, together with the upper surface of the tray 1, form a groove for placing medicine bottles. When this embodiment is installed inside a high-voltage discharge detector, the driving device can drive the turntable 2 to rotate. The rotational movement of the turntable 2 can cause the medicine bottles placed in the groove to rotate synchronously. At the same time, the through holes 3 can fix the position of the medicine bottles in the turntable 2, restricting the horizontal movement of the medicine bottles during rotation, thereby ensuring that the medicine bottles rotate under the resistance of the damping mechanism.

[0040] A damping mechanism is provided concentrically on the upper surface of tray 1, and all through holes 3 are oriented towards the damping mechanism. During the testing process, the medicine bottle is placed in the groove, and the outer wall of the medicine bottle can directly contact the damping mechanism. When the turntable 2 rotates, the medicine bottle rotates synchronously. At the same time, the damping mechanism contacts the outer wall of the medicine bottle and creates resistance to the movement of the medicine bottle with the turntable. The resistance acting on the outer wall of the medicine bottle, combined with the limiting effect of the through holes 3, jointly prevents the medicine bottle from completely following the movement of the turntable 2.

[0041] As the turntable 2 rotates continuously, the medicine bottle is continuously driven by the turntable 2. Under the interaction of the driving force of the turntable 2 and the resistance of the damping mechanism, the medicine bottle generates relative motion, thus rotating around its own axis. This rotation ensures that all parts of the medicine bottle are fully exposed within the detection range of the testing equipment, thereby improving the comprehensiveness of the detection. Furthermore, the turntable has six evenly spaced through holes 3, each capable of accommodating one medicine bottle. Therefore, six medicine bottles can be detected simultaneously, thus improving detection efficiency.

[0042] The damping mechanism includes a first damping ring 4 and a second damping ring 5. A first damping groove 6 and a second damping groove 7, which are circularly formed, are opened on the upper surface of the tray. The first damping ring 4 is embedded in the first damping groove 6, and the upper surface of the first damping ring 4 is flush with the opening of the first damping groove 6. The second damping ring 5 is embedded in the second damping groove 7, and the upper surface of the second damping ring 5 is flush with the opening of the second damping groove 7.

[0043] In this embodiment, when the turntable 2 drives the medicine bottle to rotate, the outer wall of the medicine bottle contacts the first damping ring 4 and the second damping ring 5. Since the first damping ring 4 is embedded and fixed in the first damping groove 6, and the second damping ring 5 is embedded and fixed in the second damping groove 7, it ensures that the first damping ring 4 and the second damping ring 5 will not shift or loosen during contact with the medicine bottle, thus providing stable resistance when the medicine bottle rotates with the turntable. The resistance acting on the outer wall of the medicine bottle, combined with the limiting effect of the through hole 3, jointly restricts the medicine bottle from completely following the movement of the turntable 2. As the turntable 2 continues to rotate, the medicine bottle is continuously subjected to the driving force of the turntable 2. Under the interaction of the driving force of the turntable 2 and the resistance of the damping mechanism, the medicine bottle generates relative motion, thereby rotating around its own axis.

[0044] When the medicine bottle is placed in the groove formed by the through hole 3 and the tray 1, the upper surface of the first damping ring 4 is flush with the opening of the first damping groove 6, and the upper surface of the second damping ring 5 is flush with the opening of the second damping groove 7. This ensures the flatness of the contact surface between the medicine bottle and the tray 1. Therefore, the outer wall of the medicine bottle can fully fit against the surface of the tray 1, thus preventing the medicine bottle from shaking or tilting due to uneven contact surfaces. At the same time, the upper surfaces of the first damping ring 4 and the second damping ring 5 can make close contact with the outer wall of the medicine bottle, so that the first damping ring 4 and the second damping ring 5 can provide stable resistance to the medicine bottle, ensuring the stability of the medicine bottle during its rotation.

[0045] The first damping ring 4 and the second damping ring 5 simultaneously provide resistance to the medicine bottle. Therefore, there are two resistance points acting on the outer wall of the medicine bottle. This arrangement allows for a more uniform distribution of resistance on the outer wall of the medicine bottle, thus preventing swaying or displacement caused by uneven resistance and ensuring the stability of the medicine bottle during its rotation.

[0046] The through hole 3 includes a narrow strip through hole 8. Six narrow strip through holes 8 are formed around the center of the upper surface of the turntable 2. The narrow strip through holes 8 are set close to the center of the turntable 2. Each narrow strip through hole 8 is connected to a wide strip through hole 9 at the end away from the center of the turntable 2.

[0047] In this embodiment, six narrow strip-shaped through holes 8 are formed around the center of the upper surface of the turntable 2. These narrow strip-shaped through holes 8 are located close to the center of the turntable 2, and their size matches the neck of the medicine bottle to accommodate the neck of the medicine bottle. Each narrow strip-shaped through hole 8 has a wide strip-shaped through hole 9 connected to its end away from the center of the turntable 2. The size of the wide strip-shaped through hole 9 matches the body of the medicine bottle to accommodate the body of the medicine bottle. The wide strip-shaped through hole 9 communicates with the narrow strip-shaped through holes 8, forming a through hole that matches the shape of the medicine bottle. When the medicine bottle is placed in the groove formed by the through hole 3 and the upper surface of the tray 1, the neck of the medicine bottle fits against the inner wall of the narrow strip-shaped through hole 8, and the body of the medicine bottle fits against the inner wall of the wide strip-shaped through hole 9, thereby limiting the movement of the medicine bottle during the testing process and ensuring its stability.

[0048] When turntable 2 rotates, the medicine bottle moves synchronously with it. Due to the limiting effect of the through-hole 3, the medicine bottle does not wobble or deviate during the rotation of turntable 2. Simultaneously, the upper surfaces of the first damping ring 4 and the second damping ring 5 are in close contact with the outer wall of the medicine bottle, creating resistance to the movement of the medicine bottle with turntable 2. The resistance acting on the outer wall of the medicine bottle and the limiting effect of the through-hole combine to prevent the medicine bottle from completely following the movement of turntable 2. Under the interaction of the driving force of turntable 2 and the resistance of the first damping ring 4 and the second damping ring 5, the medicine bottle rotates around its own axis, thus achieving comprehensive detection.

[0049] A circular conductive groove 11 is formed on the upper surface of the tray 1, with the center of the groove. The conductive groove 11 is located between the first damping groove 6 and the second damping groove 7. A conductive ring 10 is embedded in the conductive groove 11, and the upper surface of the conductive ring 10 is flush with the opening of the conductive groove 11.

[0050] In this embodiment, when the medicine bottle rotates with the turntable 2, its outer wall moves relative to the first damping ring 4 and the second damping ring 5, generating friction. This friction leads to charge transfer, thereby generating static electricity on the surface of the medicine bottle. During continuous rotation, static electricity gradually accumulates. When it accumulates to a certain level, it may trigger a discharge phenomenon, generating electric sparks, which could damage the detection equipment or cause a safety accident. To eliminate the hazards of static electricity, when this device is installed inside a high-voltage discharge detector, the conductive ring 10 is connected to the ground wire to release static electricity from the surface of the medicine bottle.

[0051] In this embodiment, an annular conductive groove 11 is formed on the upper surface of the tray 1, and the conductive groove 11 is located between the first damping groove 6 and the second damping groove 7. The conductive ring 10 is embedded and fixed in the conductive groove 11, which ensures that the conductive ring 10 will not shift or loosen when in contact with the medicine bottle. In addition, the upper surface of the conductive ring 10 is flush with the opening of the conductive groove 11, which ensures the flatness of the contact surface between the medicine bottle and the tray 1, so that the outer wall of the medicine bottle can fully fit with the surface of the tray 1, avoiding shaking or tilting caused by uneven contact surfaces.

[0052] When the medicine bottle is placed in the groove formed by the through hole 3 and the tray 1, the side wall of the medicine bottle is in close contact with the first damping ring 4, the second damping ring 5 and the conductive ring 10 at the same time, so that the static electricity on the surface of the medicine bottle can be released to the ground wire through the conductive ring 10, thereby avoiding the occurrence of discharge phenomenon and ensuring the safety of the detection process.

[0053] The turntable 2 has a downward-extending connecting rod 12 at the center of its bottom surface. The tray 1 has a connecting hole 13 that matches the connecting rod 12. The connecting rod 12 passes through the connecting hole 13 and is rotatably connected to the tray 1. The turntable 2 can rotate on the upper surface of the tray 1 with the connecting rod 12 as the center.

[0054] When this embodiment is installed inside a high-voltage discharge detector, the tray 1 is fixedly installed inside the detector, and the end of the connecting rod 12 is fixedly connected to the drive mechanism. After the drive mechanism is started, it drives the connecting rod 12 to rotate around its axis. The rotation of the connecting rod 12 drives the turntable 2 to rotate synchronously. The connecting rod 12 passes through the connecting hole 13 and is rotatably connected to the tray 1, allowing the turntable 2 to rotate on the upper surface of the tray 1, thereby realizing the rotation of the medicine bottle and ensuring that the outer surface of the medicine bottle can be fully inspected.

[0055] In this embodiment, the damping mechanism provides resistance to the medicine bottle rotating with the turntable 2. This resistance, combined with the limiting effect of the through-hole 3, restricts the medicine bottle from completely following the movement of the turntable 2. Under the interaction of the driving force of the turntable and the resistance of the damping mechanism, the medicine bottle rotates around its own axis. Compared with the prior art, this embodiment ensures that all parts of the medicine bottle are fully exposed within the detection range of the detection equipment through the rotation of the medicine bottle, thereby improving the comprehensiveness of the detection. Secondly, the turntable 2 is provided with 6 through-holes 3, which can simultaneously place 6 medicine bottles for detection, significantly improving the detection efficiency. In addition, by providing the conductive ring 10, the static electricity on the surface of the medicine bottle can be released in time, avoiding the discharge phenomenon that may be caused by the accumulation of static electricity, and ensuring the safety of the detection process.

[0056] The above are merely embodiments of this utility model. Commonly known technical solutions and / or characteristics are not described in detail here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the technical solution of this utility model. These modifications and improvements should also be considered within the scope of protection of this utility model, and will not affect the effectiveness of the implementation of this utility model or the practicality of the patent. The scope of protection claimed in this application shall be determined by the content of its claims, and the specific embodiments described in the specification can be used to interpret the content of the claims.
