Description

Technical Field

[0001] This invention relates to a testing device, and more particularly to a leak-proof bottle testing device for a pharmaceutical packaging production line, applicable to the field of pharmaceutical packaging production technology. Background Technology

[0002] Packaging, as a crucial link in the pharmaceutical production process, directly affects the stability and safety of drug quality. Bottled packaging, one of the most common forms of pharmaceutical packaging, relies heavily on its airtight seal to ensure that drugs are protected from moisture, oxidation, and contamination during storage and use. Poor sealing of medicine bottles can easily lead to drug deterioration, seriously threatening medication safety. Therefore, rigorous sealing tests on filled and sealed medicine bottles at the end of the pharmaceutical packaging production line, and the rejection of substandard products, are essential quality control measures to ensure that the quality of drugs leaving the factory meets standards.

[0003] Various leak detection devices for medicine bottles already exist in the prior art. For example, Chinese Patent No. CN116793591B discloses a leak detection device and method for medicine bottles used in drug production, which uses a meshing drive to drive the detection ring to rotate and adjust the position of the limiting cylinder to achieve positioning detection of the medicine bottle; another example is Chinese Patent No. CN118698926B, which discloses a leak detection device for medicine bottles that can simultaneously place and batch-detect multiple medicine bottles, thereby improving leak detection efficiency.

[0004] However, after pharmaceuticals are produced, packaged, and shipped, they still need to go through multiple stages such as warehousing, transportation, and sales. During actual transportation, bottled pharmaceuticals inevitably experience varying degrees of bumps and vibrations. This vibrational environment can cause the sealing structure of bottles that were originally sealed properly under static conditions (such as the connection between the cap and the bottle body, and the sealing ring) to loosen, deform, or even be damaged due to continuous mechanical stress, leading to leakage problems during subsequent distribution. Existing bottle leak detection devices mostly conduct their detection process in a static environment, failing to effectively simulate the vibration conditions that bottles may encounter during transportation and other stages. Therefore, it is difficult to comprehensively assess the long-term sealing performance and structural reliability of bottles under dynamic disturbances. This limitation of static detection may prevent the timely detection of some sealing defects that only appear under dynamic conditions, significantly reducing the reliability and accuracy of the detection results and making it difficult to fully meet the stringent requirements for quality assurance throughout the entire life cycle of pharmaceuticals. Therefore, we propose a leak-proof bottle detection device for pharmaceutical packaging production lines. Summary of the Invention

[0005] The technical problem that this invention aims to solve in view of the above-mentioned prior art is that the existing medicine bottle leak detection devices are mostly carried out in a static environment, which fails to effectively simulate the vibration conditions that medicines may encounter during transportation and other processes, and makes it difficult to comprehensively evaluate the long-term sealing performance and structural reliability of medicine bottles under dynamic interference.

[0006] To address the aforementioned problems, this invention provides a leak-proof bottle detection device for a pharmaceutical packaging production line, comprising a detection platform with multiple detection slots evenly distributed along a straight line. A matching sealing cover is installed above each detection slot. A vertically upward-mounted sealing electric push rod is fixedly connected to the outer wall of the detection platform, with its output end fixedly connected to the sealing cover. Each detection slot's bottom end is connected to a vertically mounted inflation pipe, and each inflation pipe is equipped with a pressure reducing valve and an inflation solenoid valve, with the pressure reducing valve located below the inflation solenoid valve. A gas supply cylinder filled with compressed air is located on one side of the detection platform, and its outlet is connected to a gas delivery pipe. The end of the gas delivery pipe furthest from the gas supply cylinder is sealed. The bottom end of each inflation pipe is connected to the gas delivery pipe. Each detection slot is equipped with a slot pressure sensor.

[0007] In the aforementioned leak-proof bottle testing device for pharmaceutical packaging production lines, when testing the sealing performance of medicine bottles, airflow can be used to cause the medicine bottles to vibrate, simulating the vibration conditions that medicine bottles may encounter during transportation and other processes. This allows for a comprehensive evaluation of the long-term sealing performance and structural reliability of medicine bottles under dynamic disturbances.

[0008] As a further improvement of this application, the bottom end of the sealing cover plate is fixedly connected with a plurality of auxiliary vibration springs that can be inserted into the detection slot. The number of auxiliary vibration springs is equal to the number of detection slots and they correspond one-to-one. The auxiliary vibration springs are located directly above the corresponding detection slots, and the bottom end of each auxiliary vibration spring is fixedly connected with a strike plate that can be inserted into the detection slot.

[0009] As a further improvement of this application, the bottom end of the impact plate is fixedly connected to a matching elastic pad, and the inner wall of the detection groove is provided with a matching elastic liner, with the inflation tube penetrating through the elastic liner.

[0010] As a further improvement of this application, the detection device also includes a leak detection intelligent control system, which includes a leak detection setting module, a leak detection control module, and a leak detection analysis module. The leak detection setting module is signal-connected to the leak detection control module and the leak detection analysis module. The leak detection control module is signal-connected to the sealing tank electric push rod and the inflation solenoid valve. The tank air pressure sensor is signal-connected to the leak detection control module and the leak detection analysis module. The leak detection analysis module is signal-connected to the leak detection control module.

[0011] As a further improvement of this application, multiple feedback lights are fixedly connected to the top of the sealing cover plate. The number of feedback lights is equal to the number of detection slots and they correspond one-to-one. The feedback lights are located directly above the corresponding detection slots, and the leak detection analysis module is connected to the feedback light signals.

[0012] As another improvement of this application, the detection device also includes a loading robotic arm for placing the medicine bottle to be tested into the detection tank, and the leak detection intelligent control system also includes an output control module, which is signal-connected to the loading robotic arm and the leak detection control module.

[0013] As a supplement to another improvement of this application, the testing device also includes a discharge sorting mechanism, which includes a two-axis moving platform located on the side of the testing table away from the sealing groove electric push rod. A support base configured as a step is fixedly installed on the two-axis moving platform, and two bottle-clamping electric push rods are fixedly installed on the support base. The discharge sorting mechanism also includes two clamping plates, and the output ends of the two bottle-clamping electric push rods are respectively fixedly connected to the two clamping plates.

[0014] As a supplement to another improvement in this application, the two clamps are located on the left and right sides of the testing platform, respectively. The leak detection setting module and the leak detection analysis module are both connected to the upper output control module. The upper output control module is connected to the two-axis moving platform, the bottle clamping electric push rod, and the inflation solenoid valve.

[0015] As a supplement to another improvement of this application, the leak detection intelligent control system also includes a gas replenishment reminder module. A cylinder pressure sensor is installed inside the gas supply cylinder. Both the leak detection setting module and the cylinder pressure sensor are connected to the gas replenishment reminder module.

[0016] In summary, the testing device in this application, when performing a sealing test on medicine bottles, can induce vibration in the medicine bottle by simultaneously filling the testing tank with air, simulating the vibration conditions that medicine bottles may encounter during transportation and other processes. This allows for a comprehensive evaluation of the long-term sealing performance and structural reliability of the medicine bottle under dynamic interference, significantly improving the reliability and accuracy of the test results. Furthermore, through the combined setup of a leak detection intelligent control system, a material discharge sorting mechanism, and a feeding robotic arm, this application not only fully automates the testing process but also automatically sorts qualified and unqualified medicine bottles after the test, further improving testing efficiency.

Detailed Implementation

[0019] The three embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0020] First implementation method: Figures 1-3 This invention discloses a leak-proof bottle detection device for a pharmaceutical packaging production line, comprising a detection platform 101 with multiple detection slots 102 evenly distributed along a straight line on the platform 101. A matching sealing cover plate 103 is disposed above each detection slot 102. A vertically upward-mounted sealing electric push rod 104 is fixedly connected to the outer wall of the detection platform 101, and the output end of the sealing electric push rod 104 is fixedly connected to the sealing cover plate 103. A vertically mounted air inlet pipe 105 is connected to the bottom end of each detection slot 102. Each inflation tube 105 is equipped with a pressure reducing valve 106 and an inflation solenoid valve 107, with the pressure reducing valve 106 located below the inflation solenoid valve 107. A gas supply cylinder 108 is provided on one side of the test platform 101, and the gas supply cylinder 108 is filled with compressed air. The outlet of the gas supply cylinder 108 is connected to a gas delivery pipe 109, and the end of the gas delivery pipe 109 away from the gas supply cylinder 108 is sealed. The bottom end of each inflation tube 105 is connected to the gas delivery pipe 109. A tank pressure sensor is provided in each test slot 102.

[0021] During testing, the medicine bottle to be tested is placed in the testing slot 102. Each testing slot 102 can hold one medicine bottle, and multiple testing slots 102 can hold multiple medicine bottles, so that multiple medicine bottles can be tested at the same time. The control of the sealing groove electric push rod 104 drives the sealing groove cover plate 103 to move downward until the sealing groove cover plate 103 abuts against the test table 101 to seal the top of the test groove 102; By repeatedly opening and closing the inflation solenoid valve 107, each time the inflation solenoid valve 107 is opened, the compressed air in the gas supply cylinder 108 will be sprayed into the detection tank 102 through the gas delivery pipe 109 and the inflation pipe 105. This not only inflates the detection tank 102, increasing the air pressure in the detection tank 102, but also creates an airflow that impacts the medicine bottle, causing the medicine bottle to move upward. After the inflation solenoid valve 107 is closed, the medicine bottle will fall downward under its own weight. Therefore, by repeatedly opening and closing the inflation solenoid valve 107, the medicine bottle can be made to vibrate up and down repeatedly to simulate the vibration conditions that the medicine bottle may encounter during transportation and other processes. After repeatedly opening and closing the inflation solenoid valve 107, observe the air pressure data monitored by the tank pressure sensor. Since the air pressure inside the detection tank 102 is higher than the air pressure inside the medicine bottle, if there is a problem with the seal of the medicine bottle, the air inside the detection tank 102 will continuously flow into the medicine bottle, causing the air pressure inside the detection tank 102 to continuously decrease. Therefore, if the air pressure data monitored by the tank pressure sensor remains almost unchanged (a fluctuation threshold can be reasonably set according to the actual situation; if the fluctuation of the air pressure data is within the fluctuation threshold, it is considered that the air pressure data remains almost unchanged), it indicates that the seal of the medicine bottle in the corresponding detection tank 102 is good. Conversely, if the air pressure data monitored by the tank pressure sensor continues to decrease, it indicates that there is a problem with the seal of the medicine bottle in the corresponding detection tank 102.

[0022] The pressure reducing valve 106 is used to reduce and regulate the air pressure, making the airflow impacting the medicine bottle stable and controllable, and preventing damage to the medicine bottle due to excessive airflow impact. In addition, before starting the test, the opening degree of the inflation solenoid valve 107 can be preset according to the actual situation, on the premise that the medicine bottle can move upward smoothly under the impact of the airflow. This opening degree is recorded as the detection opening degree. The detection opening degree is less than the maximum opening degree of the inflation solenoid valve 107. During the test, the opening of the inflation solenoid valve 107 is controlled according to the detection opening degree each time it is opened. This can further precisely control the impact of the airflow on the medicine bottle, thereby further preventing damage to the medicine bottle due to excessive airflow impact.

[0023] Therefore, the testing device in this application can, while filling the testing tank 102 with air, use the airflow to make the medicine bottle vibrate, so as to simulate the vibration conditions that the medicine bottle may encounter in transportation and other processes. This allows for a comprehensive evaluation of the long-term sealing performance and structural reliability of the medicine bottle under dynamic interference, and significantly improves the reliability and accuracy of the test results.

[0024] Second implementation method: Figures 4-6 This invention discloses a leak-proof bottle detection device for a pharmaceutical packaging production line. Unlike the first embodiment, the bottom end of the sealing cover plate 103 is fixedly connected with a plurality of auxiliary vibration springs 201 that can be inserted into the detection groove 102. The number of auxiliary vibration springs 201 and the detection groove 102 are equal and correspond one-to-one. The auxiliary vibration springs 201 are located directly above the corresponding detection groove 102. The bottom end of each auxiliary vibration spring 201 is fixedly connected with a strike plate 202 that can be inserted into the detection groove 102.

[0025] During testing, after the sealing cover plate 103 abuts against the testing table 101, the auxiliary vibration spring 201 and the impact plate 202 are inserted into the testing slot 102. When the medicine bottle moves upward under the action of airflow, the medicine bottle will impact the impact plate 202 and compress the auxiliary vibration spring 201. Under the synergistic action of airflow impact and auxiliary vibration spring 201, the medicine bottle can be made to vibrate up and down repeatedly. Therefore, in this embodiment, during testing, after opening the inflation solenoid valve 107 according to the testing opening degree, it is only necessary to close the inflation solenoid valve 107 after the air pressure in the testing slot 102 reaches a certain level. There is no need to repeatedly open and close the inflation solenoid valve 107 to achieve the up and down vibration of the medicine bottle, thereby optimizing the testing process and improving testing efficiency.

[0026] An elastic pad 203 is fixedly connected to the bottom of the impact plate 202, and an elastic liner 204 is provided on the inner wall of the detection groove 102. The inflation tube 105 passes through the elastic liner 204. The elastic pad 203 and the elastic liner 204 can play a buffering and protective role to prevent the medicine bottle from being damaged due to the detection.

[0027] The detection device also includes a leak detection intelligent control system, which includes a leak detection setting module, a leak detection control module, and a leak detection analysis module. The leak detection setting module is connected to the leak detection control module and the leak detection analysis module by signal. The leak detection control module is connected to the sealing groove electric push rod 104 and the inflation solenoid valve 107 by signal. The groove air pressure sensor is connected to the leak detection control module and the leak detection analysis module by signal. The leak detection analysis module is connected to the leak detection control module by signal.

[0028] Multiple feedback lights 205 are fixedly connected to the top of the sealing cover plate 103. The number of feedback lights 205 is equal to that of the detection slots 102 and they correspond one-to-one. The feedback lights 205 are located directly above the corresponding detection slots 102. The leak detection analysis module is connected to the feedback lights 205.

[0029] In this embodiment, before testing, the detection opening, fluctuation threshold, and detection air pressure are reasonably set by the leak detection setting module according to the actual situation. During testing, after placing medicine bottles into each detection slot 102, the leak detection control module controls the detection slot 102 to move the sealing cover plate 103 downwards until the sealing cover plate 103 abuts against the detection platform 101. Then, the leak detection control module opens the inflation solenoid valve 107 according to the detection opening to inflate the detection slot 102. Under the synergistic action of the airflow and the auxiliary vibration spring 201, the medicine bottles vibrate up and down. The air pressure data monitored by the slot air pressure sensor is transmitted to the leak detection control module in real time. When the air pressure in the detection slot 102 reaches the detection threshold, the leak detection control module will initiate the test. After the air pressure is released, the leak detection control module will close the inflation solenoid valve 107 to stop inflation. The air pressure data monitored by the tank air pressure sensor will also be transmitted to the leak detection analysis module in real time. The leak detection analysis module will analyze the air pressure data according to the fluctuation threshold to determine whether the medicine bottle is leaking or whether there is a problem with the sealing. When the leak detection analysis module determines that there is a problem with the sealing of a medicine bottle in a certain detection tank 102, the leak detection analysis module will light up the corresponding feedback light 205 to provide feedback to the relevant personnel. After the judgment is completed, the leak detection analysis module will send a signal to the leak detection control module, causing the leak detection control module to control the sealing tank electric push rod 104 to drive the sealing tank cover plate 103 to move upward and reset. Therefore, the leak detection intelligent control system not only improves the automation level of detection and greatly reduces manual operation, but also realizes automatic analysis and judgment, which can effectively avoid errors caused by manual observation and judgment, and further improve the accuracy of detection results.

[0030] The third implementation method: Figures 7-9 The present invention discloses a leak-proof bottle detection device for a pharmaceutical packaging production line. Unlike the second embodiment, the detection device further includes a loading robotic arm (not shown in the figure, the loading robotic arm adopts existing technology, and its specific structure is not described here) for placing the medicine bottle to be tested into the detection tank 102. The leak detection intelligent control system also includes an output control module, which is signal-connected to the loading robotic arm and the leak detection control module.

[0031] In this embodiment, during testing, the top-out control module controls the feeding robotic arm to grab the medicine bottle to be tested and place it into the testing slot 102, thus eliminating the need for manual placement of the medicine bottle and further improving the automation of the testing. After the medicine bottle is placed, the top-out control module sends a signal to the leak detection control module, causing the leak detection control module to control the testing slot 102 to move the sealing cover plate 103 downward, so that the testing is performed automatically and in an orderly manner.

[0032] The testing device also includes a discharge sorting mechanism 003, which includes a two-axis moving platform 301 located on the side of the testing table 101 away from the sealing slot electric push rod 104. A stepped support base 302 is fixedly installed on the two-axis moving platform 301. Two bottle-clamping electric push rods 303 are fixedly installed on the support base 302. The discharge sorting mechanism 003 also includes two clamping plates 304, and the output ends of the two bottle-clamping electric push rods 303 are fixedly connected to the two clamping plates 304 respectively.

[0033] Two clamping plates 304 are located on the left and right sides of the testing platform 101, respectively. The leak detection setting module and the leak detection analysis module are both connected to the upper output control module. The upper output control module is connected to the two-axis moving platform 301, the bottle clamping electric push rod 303, and the inflation solenoid valve 107.

[0034] In this embodiment, before the test, the discharge opening needs to be reasonably set by the leak detection setting module according to the actual situation. The discharge opening is greater than the detection opening. That is, when the inflation solenoid valve 107 is opened with the discharge opening, the intensity of the airflow ejected from the inflation pipe 105 is greater than the intensity of the airflow ejected from the inflation pipe 105 when the inflation solenoid valve 107 is opened with the detection opening. And each time the test is performed, after the result is determined, the leak detection analysis module will send the judgment result to the upper control module. After the test is completed, that is, after the leak detection control module controls the sealing groove electric push rod 104 to move the sealing groove cover plate 103 upward and reset, the leak detection control module will send a signal to the upper output control module. After receiving the signal, the upper output control module will control the two-axis moving platform 301 to move the support base 302 upward, which can drive the clamping plate 304 upward until the height of the clamping plate 304 is between the test table 101 and the sealing groove cover plate 103 (the specific movement distance is preset by the leak detection setting module according to the actual situation). For ease of description, after each test and result interpretation, let's define the detection slot 102 with no internal sealing issues as A and the detection slot 102 with internal sealing issues as B. After the clamping plate 304 has moved upwards, the upward control module, based on the judgment result and according to the discharge opening, opens the inflation solenoid valve 107 corresponding to A (if all medicine bottles have no sealing issues, all inflation solenoid valves 107 are opened). Under the impact of the strong airflow, the medicine bottles with no sealing issues will move upwards to outside the detection slot 102 and be positioned between the two clamping plates 304, and then the upward control... The control module controls the bottle-clamping electric push rod 303 to move the two clamping plates 304 toward each other to clamp the medicine bottle. Then, the upper control module controls the two-axis moving platform 301 to move the support base 302 to the left until the two clamping plates 304 and the medicine bottle are all moved to the left side of the detection table 101. Then, the upper control module controls the bottle-clamping electric push rod 303 to move the two clamping plates 304 in opposite directions to release the clamping of the medicine bottle, thereby completing the discharge of the medicine bottle with no sealing problem. Then, the upper control module controls the two-axis moving platform 301 to move the support base 302 to the right to reset. Subsequently, based on the judgment result and according to the discharge opening, the upper discharge control module opens the inflation solenoid valve 107 corresponding to B, and completes the discharge of the medicine bottle with sealing problems according to the above discharge operation for medicine bottles with no sealing problems. However, the difference is that after the medicine bottle is clamped by the clamping plate 304, the upper discharge control module will control the two-axis moving platform 301 to drive the support base 302 to move to the right. That is, the medicine bottle with sealing problems will be discharged to the right side of the detection platform 101. Of course, the medicine bottle with no sealing problems can also be discharged to the right side of the detection platform 101 and the medicine bottle with sealing problems can be discharged to the left side of the detection platform 101, as long as the two types of medicine bottles are not discharged to the same side of the detection platform 101. In addition, if all medicine bottles have no sealing problems, this step is skipped. Finally, the upper control module will control the two-axis moving platform 301 to drive the support base 302 to move downwards and reset; Therefore, by combining the leak detection intelligent control system, the discharge sorting mechanism 003, and the feeding robotic arm, not only has the detection been fully automated, but qualified and unqualified medicine bottles can also be automatically sorted after the detection is completed, further improving the detection efficiency.

[0035] The leak detection and intelligent control system also includes a gas replenishment reminder module. A cylinder pressure sensor is installed inside the gas supply cylinder 108. Both the leak detection setting module and the cylinder pressure sensor are connected to the gas replenishment reminder module. The cylinder pressure sensor is used to monitor the compressed air pressure inside the gas supply cylinder 108, and the pressure data detected by the cylinder pressure sensor is transmitted to the gas replenishment reminder module in real time. A pressure threshold is reasonably preset by the leak detection setting module. When the pressure inside the gas supply cylinder 108 is lower than the pressure threshold, the gas replenishment reminder module will issue a prompt sound to remind the relevant technicians, prompting them to replenish the gas supply cylinder 108 in time to prevent the detection from being affected.

[0036] In light of current practical needs, the above-described embodiments adopted in this application are not limited to this scope of protection. Various changes made within the knowledge of those skilled in the art without departing from the concept of this application still fall within the protection scope of this invention.
