DETAILED DESCRIPTION
[0046] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.
[0047] Example 1
[0048] like Figures 1 to 3 As shown, this embodiment provides a vacuum leak detector, comprising:
[0049] The box body 1 has a vacuum chamber 2, and the vacuum chamber 2 is used for detecting medicine bottles;
[0050] Sealing component 3, sealing component 3 includes:
[0051] A first sealing plate 4 is hingedly arranged on the box body 1;
[0052] The second sealing plate 5 is hingedly mounted on the box body 1. After the first sealing plate 4 and the second sealing plate 5 rotate, they are used to seal the vacuum chamber 2.
[0053] The supporting assembly 6 is also included, and the supporting assembly 6 includes:
[0054] The upper tray 7 is slidably arranged on the first sealing plate 4 . After the upper tray 7 rotates with the first sealing plate 4 , it is used to deliver the medicine bottles into the vacuum chamber 2 .
[0055] In this embodiment, in existing technology, after the medicine bottle enters the leak detector, the door must be closed before vacuum extraction can be performed. First, closing the door before vacuum extraction can damage the medicine bottle or the medicine inside. This situation is particularly noticeable in high-temperature or high-humidity environments. Second, closing the door before vacuum extraction can result in uneven distribution of the medicine inside the medicine bottle, which can affect the accuracy and repeatability of leak detection.
[0056] In order to solve the above problems, this solution is to set the supporting component 6 for supporting the medicine bottle on the sealing plate, and then when the sealing plate is closed, the medicine bottle to be inspected can be directly placed in the vacuum detection box, wherein the box body 1 of the vacuum detection box can be used to vacuumize and detect the medicine bottle, so as to realize vacuum detection of the medicine bottle.
[0057] The specific method is that an upper tray 7 for supporting medicine bottles is installed on the first sealing plate 4, so that the upper tray 7 can open and close the box body 1 as the first sealing plate 4 rotates. When the first sealing plate 4 and the second sealing plate 5 rotate, the upper tray 7 enters the box body 1 and is in a waiting position for inspection. At this time, the vacuum box is in a completely sealed state to ensure the subsequent vacuuming and testing. In this way, the present solution can directly perform vacuum extraction operations after closing the sealing plate, which greatly improves work efficiency and has high practicality.
[0058] Furthermore, the upper tray 7 has a plurality of first placement holes 8, the first placement holes 8 are used to place medicine bottles, the first sealing plate 4 has a first upper slide groove 9 and a first lower slide groove 10, the second sealing plate 5 has a second upper slide groove 11 and a second lower slide groove 12, after the first sealing plate 4 and the second sealing plate 5 rotate, the first upper slide groove 9 and the second upper slide groove 11 form a first channel, the first lower slide groove 10 and the second lower slide groove 12 form a second channel, the upper tray 7 is slidably arranged in the first channel, and the supporting assembly 6 further includes:
[0059] The lower tray 15 is slidably disposed on the second sealing plate 5 and has a plurality of second placement holes 16 . The lower tray 15 rotates with the second sealing plate 5 and slides along the second channel so that the first placement holes 8 are correspondingly connected to the second placement holes 16 .
[0060] In this embodiment, in order to further improve the detection efficiency, a lower tray 15 is also provided on the second sealing plate 5. The introduction of the lower tray 15 further improves the processing efficiency of this scheme. In particular, the lower tray 15 in this scheme can be used to support unqualified medicine bottles. When the upper tray 7 detects that the medicine bottles are leaking, the medicine bottles can be arranged from the first placement hole 8 to the lower tray 15. The specific method is that the upper tray 7 and the lower tray 15 can slide along the first channel and the second channel. When the first sealing plate 4 and the second sealing plate 5 are closed, since there is a gap between the upper tray 7 and the lower tray 15, the two trays are slid so that the corresponding first placement hole 8 and the second placement hole 16 thereon are in corresponding positions. Then, when unqualified medicine bottles are detected, they can be discharged and supported by the lower tray 15. After the detection is completed, since the upper tray 7 is installed on the first sealing plate 4 and the lower tray 15 is installed on the second sealing plate 5, the qualified products and the unqualified products are directly separated by opening the warehouse door, so that the processing efficiency is further improved.
[0061] Furthermore, the supporting assembly 6 further includes a plurality of clamping assemblies 17, with one clamping assembly 17 being provided on each first placement hole 8. The clamping assembly 17 includes:
[0062] A first clamping member 18 is slidably disposed on the upper tray 7 and is located on one side of the first placement hole 8;
[0063] The second clamping member 19 is slidably arranged on the lower tray 15 and is located on the other side of the first placement hole 8. The first clamping member 18 and the second clamping member 19 form a clamping space. After the first clamping member 18 and the second clamping member 19 slide, they are used to adjust the size of the clamping space.
[0064] In this embodiment, the present scheme fixes and clamps the medicine bottle to be tested by arranging a clamping assembly 17 for clamping the medicine bottle above the first placement hole 8, and the clamping member has a sensor, which can be a liquid sensor or a weight sensor. When the medicine bottle to be tested is empty, a weight sensor can be used. If the medicine bottle leaks in a vacuum, its weight is bound to change. At this time, the sensor detects the change, and the first clamping member 18 and the second clamping member 19 slide so that the unqualified medicine bottle can slide into the lower tray 15. Similarly, when the medicine bottle to be tested is filled with liquid medicine, the sensor can be a liquid sensing sensor. In this way, during the testing process, the upper tray 7 can support qualified products, and the lower tray 15 can receive unqualified products discharged by the upper tray 7, so that the practicality of this scheme is further improved.
[0065] Furthermore, the supporting assembly 6 further includes a communication assembly 20, which has several components. The communication assembly 20 includes:
[0066] The first connecting pipe 21 is provided on the upper tray 7 and is located below the first placement hole 8;

[0068] The second connecting pipe 23 is provided on the lower tray 15 and is located above the second placement hole 16;
[0069] The second magnetic member 24 is provided on the telescopic end of the second connecting tube 23 . After the upper tray 7 and the lower tray 15 slide, the first magnetic member 22 and the second magnetic member 24 are magnetically engaged with each other to connect the first connecting tube 21 and the second connecting tube 23 .
[0070] In this embodiment, in order to further ensure the smooth discharge of medicine bottles from the upper tray 7 to the lower tray 15, this solution provides a first connecting tube 21 with a first magnetic component 22 on the lower end face of the upper tray 7, which is made of a retractable flexible material, and a second connecting tube 23 with a second magnetic component 24 on the upper end face of the lower tray 15. When the two trays slide to corresponding positions, the two magnetic components magnetically cooperate with each other to drive the connecting tube to extend, thereby forming a connecting channel for passing unqualified medicine bottles between the first placement hole 8 and the second placement hole 16, thereby avoiding the problem that the lower tray 15 cannot support the medicine bottles due to falling deviation of the medicine bottles during the falling process.
[0071] Furthermore, the upper tray 7 has a plurality of positioning slots 25, and the supporting assembly 6 further includes:
[0072] There are a plurality of positioning rods 26 , which are spaced apart and arranged on the lower tray 15 ;
[0073] There are several positioning members 27 , and each end of the positioning rod 26 is provided with a positioning member 27 . After the upper tray 7 and the lower tray 15 rotate and move, the positioning member 27 cooperates with the positioning groove 25 .
[0074] In this embodiment, in order to ensure that the two trays can stop and move at appropriate positions when sliding, this solution is provided with a positioning member 27 for positioning and stopping, which is connected to the lower tray 15 through a positioning rod 26. When the two trays slide, the positioning member 27 is correspondingly engaged with the positioning groove 25 of the upper tray 7, indicating that the placement holes of the two trays are in a state of facing each other, that is, the sliding is stopped and subsequent inspection operations are carried out.
[0075] Furthermore, the connectivity component 20 further includes:
[0076] There are a plurality of cleaning rings 28 , all rotatably disposed in the second communicating pipe 23 .
[0077] In this embodiment, since there is liquid medicine in the medicine bottle, if the medicine bottle leaks and the liquid medicine is left out, in order to ensure the cleanliness of the entire device, this solution provides a cleaning ring 28 for cleaning inside the second connecting tube 23. The outer wall of the medicine bottle is cleaned by rotating the cleaning ring 28 to ensure the cleanliness of the entire device.
[0078] Furthermore, the lower tray 15 further has a receiving cavity 29, and the plurality of second placement holes 16 are all connected to the receiving cavity 29. The supporting assembly 6 further includes a cleaning assembly 30, which includes:
[0079] A cleaning member 31 is slidably disposed in the receiving chamber 29;
[0080] The baffle 32 is hingedly mounted on the lower tray 15. After the cleaning member 31 slides, it drives the baffle 32 to rotate. After the baffle 32 rotates, it is used to open or close the storage chamber 29.
[0081] There are a plurality of elastic members 33 , one end of which is disposed on the lower tray 15 and the other end of which is disposed on the baffle 32 . The elastic members 33 are used to provide a force for the baffle 32 to close the storage cavity 29 .
[0082] In this embodiment, in order to facilitate the storage and cleaning of waste medicine bottles in the lower tray 15, this solution is provided with a storage cavity 29 for storing medicine bottles on the lower tray 15. At the same time, the storage cavity 29 has a cleaning pusher 31 for the user to push out the medicine bottles. When the entire system inspection is completed, the cleaning pusher 31 pushes the medicine bottles in the storage cavity 29 to complete the action of discharging the medicine bottles. At the same time, in order to prevent the medicine bottles from scattering during the storage process, this solution is also hingedly installed with a baffle 32, and also has an elastic member 33 for providing the baffle 32 to abut on the lower tray 15. When the medicine bottles are pushed out, the baffle 32 rotates to complete the unloading.
[0083] Furthermore, the cleaning component 30 further includes:
[0084] There are several mounting rods 34, all of which are rotatably mounted on the cleaning pusher 31;
[0085] The cleaning member 35 is sleeved on the plurality of mounting rods 34 . The cleaning member 35 abuts against the receiving cavity 29 . After the cleaning push member 31 slides, the cleaning member 35 rotates along with the mounting rods 34 .
[0086] In this embodiment, in order to clean the medicine liquid leaked from the storage chamber 29, a cleaning member 35 is further provided behind the cleaning pusher 31. The cleaning pusher 31 drives the cleaning member 35 to move, thereby clearing the medicine liquid in the storage chamber 29. At the same time, since the cleaning member 35 can extend out of the storage chamber 29, the cleaning member 35 can be cleaned and replaced more conveniently.
[0087] Furthermore, the second sealing plate 5 further has a snap-fit groove 36, and the sealing assembly 3 further includes:
