[0031] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory and should not have any limiting effect on the scope of protection of the present invention.

[0032] See also Figures 1 to 12 In a specific embodiment, an electronic micropore leak detector for row-up plastic ampoules includes a detection mesh belt for conveying row-up plastic ampoules 11, a detection station is provided on the detection mesh belt, and a detection electrode is provided on the detection station; the detection electrode is composed of an emitter probe and a receiver; the detection station includes a bottle body detection station and a head and tail detection station; at the bottle body detection station, the direction of the tangent line of the row-up plastic ampoules 11 is consistent with the conveying direction; at the head and tail detection station, the direction of the tangent line of the row-up plastic ampoules 11 is perpendicular to the conveying direction; the end of the bottle body detection emitter probe 12 at the bottle body detection station matches the shape of the upper surface of the bottle body of the row-up plastic ampoules 11.

[0033] like Figure 3 As shown, the emitter probe tip on the bottle body detection station is provided with grooves, which cooperate with the surface of the row of plastic ampoules 11 and can detect the depression at the cutting line position of the row of plastic ampoules.

[0034] like Figure 1 As shown, in order to improve the detection accuracy, the bottle body inspection of the row of plastic ampoules is divided into two inspections. Based on the above embodiment, the bottle body inspection station is further optimized and consists of a middle bottle body inspection station 4 and two side bottle body inspection stations 5. The middle bottle body inspection station 4 is used to inspect the ampoule body surface in the middle part of the row of plastic ampoules; while the two side bottle body inspection stations 5 are used to inspect the ampoule body surface on both sides of the row of plastic ampoules.

[0035] like Figure 1 As shown, based on the above embodiment, the head and tail inspection stations are further optimized, and include a head inspection station 9 and a tail inspection station 10. The head inspection station 9 is specifically used to detect defects at the head position of the row of plastic ampoules; while the tail inspection station 10 is used to detect defects at the tail of the row of plastic ampoules.

[0036] like Figure 6 As shown, based on the above embodiment, emitter probes are arranged above and below the heads of the row of plastic ampoules 11 at the head detection station 9. The emitter probes are symmetrically distributed.

[0037] In order to fill the detection position with liquid medicine and improve the detection accuracy, the above embodiment is further optimized. On the head detection station 9, the heads of the row of plastic ampoules 11 are tilted downward to fill the detection position with liquid medicine.

[0038] like Figure 4 As shown, based on the above embodiment, it is further optimized that multiple groups of equipotentially connected detection electrodes that can detect multiple ampoules one after another are arranged in parallel on the bottle body detection station.

[0039] like Figure 1 、 11 As shown, in order to realize the detection of the upper and lower surfaces of the bottle body and to realize the comprehensive detection of the bottle head and the bottle tail, the above embodiment is further optimized. At least two groups of bottle body detection stations are provided, and a first turning mechanism 6 for turning the upper and lower surfaces of the row of plastic ampoules 11 is provided between each group; at least two groups of head and tail detection stations are provided, and a second turning mechanism 19 for turning the upper and lower surfaces of the row of plastic ampoules 11 is provided between each group.

[0040] like Figure 1 As shown, based on the above embodiment, the detection mesh belt is further optimized, and the detection mesh belt includes a first detection mesh belt 3 and a second detection mesh belt 18; a bottle body detection station is set on the first detection mesh belt 3; a head and tail detection station is set on the second detection mesh belt 18; the first detection mesh belt 3 is distributed perpendicular to the second detection mesh belt 18; a bottle pushing mechanism 7 is provided between the first detection mesh belt 3 and the second detection mesh belt 18 for pushing the row of plastic ampoules 11 on the first detection mesh belt 3 to the second detection mesh belt 18.

[0041] like Figure 1 As shown, based on the above embodiment, an acceleration mesh belt 2 is further optimized and provided upstream of the detection mesh belt for separating the row of plastic ampoules 11 into intervals and then sending them to the detection mesh belt for detection.

[0042] like Figure 1 、 9 As shown, based on the above embodiment, an oscillation mechanism 8 is provided upstream of the head and tail detection station for oscillating the row of plastic ampoules 11 so that the heads are filled with liquid medicine.

[0043] The specific working principle of the present invention is:

[0044] like Figure 1 As shown, the row of plastic ampoules 11 are connected or placed manually and enter the bottle feeding mesh belt 1. The bottle feeding mesh belt 1 transports the row of plastic ampoules 11 forward, and the accelerating mesh belt 2 pulls the row of plastic ampoules 11 apart (the speed of the accelerating mesh belt is very fast, about twice that of the detection mesh belt), and then waits for the detection mesh belt. When the detection mesh belt is in a suitable position, the accelerating mesh belt transports the row of plastic ampoules to the work station of the detection mesh belt.

[0045] The push rod installed on the detection mesh belt pushes the row of plastic ampoules forward; then it passes through the middle bottle body detection station 4, which detects the bottle body and the bottle body cutting line. At this time, the relative positions of the bottle body, the bottle body cutting line and the detection electrode are as follows: Figure 3 shown.

[0046] like Figure 3 As shown, multiple sets of detection electrodes, including bottle body detection emitting probes 12 and bottle body detection receiving electrodes 13, are arranged in the same bottle body detection station. The emitting probes and receiving electrodes of these detection electrodes are all connected to the same potential. The distance between each set of detection electrodes is greater than the length of the row of plastic ampoules. This ensures that the row of plastic ampoules cannot contact the two sets of detection electrodes one by one, allowing a single high-voltage power supply to detect multiple row of plastic ampoules one by one.

[0047] Then it passes through the bottle body inspection stations 5 on both sides. The shapes and relative positions of the detection electrodes of the bottle body inspection stations 5 on both sides are the same as those of the middle bottle body inspection station 4. The difference is that the middle bottle body inspection station 4 detects the ampoules in the middle part of the row of plastic ampoules, while the bottle body inspection stations 5 on both sides detect the ampoules on both sides of the row of plastic ampoules.

[0048] The first turning mechanism 6 then flips the row of plastic ampoules 11, turning the lower surface over. The turning wheels of the first turning mechanism 6 have parallel blades, sandwiching the row of plastic ampoules to prevent them from shaking during turning, which could cause poor operation. After turning, the ampoules pass through the next set of two-side bottle inspection stations 5 and the middle bottle inspection station 4 for inspection.

[0049] Then, the row of plastic ampoules 11 are pushed onto the second detection mesh belt 18 by the bottle pushing mechanism 7; the second detection mesh belt 18 is arranged at 90 degrees to the first detection mesh belt.

[0050] The structure of the bottle pushing mechanism 7 is as follows: Figure 5-6 As shown, the servo motor 71 drives the synchronous belt 72 to move, and a push rod 73 is provided on the synchronous belt 72 to move synchronously; the push rod 73 pushes the row of plastic ampoules 11 on the first detection mesh belt 3 to the second detection mesh belt 18.

[0051] After the row of plastic ampoules 11 enters the second detection mesh belt 18, the oscillating mechanism 8 on the second detection mesh belt 18 oscillates the row of plastic ampoules 11 so that the head is filled with liquid medicine (the head has a small diameter and is difficult for liquid medicine to enter when placed flat).

[0052] The structure of the oscillation mechanism 8 is as follows: Figure 9As shown, it includes a synchronous belt 72 for conveying the row of plastic ampoules 11, a connecting rod 83 is provided above the synchronous belt 72, one end of the connecting rod 83 is connected to the linear reciprocating motion mechanism, and a fence frame is provided below the other end to push the row of plastic ampoules 11 to swing in the horizontal plane; the fence frame is composed of a first fence plate 81 and a second fence plate 82; the row of plastic ampoules 11 is conveyed between the first fence plate 81 and the second fence plate 82.

[0053] The oscillation mechanism 8 is installed above the synchronous belt 72. A push rod 73 is distributed on the synchronous belt 72. The synchronous belt 72 is arranged between the second detection mesh belt 18. The row of plastic ampoules 11 moves on the second detection mesh belt 18. The synchronous belt 72 drives the row of plastic ampoules 11 to move forward through the push rod 73. A first fence plate 81 and a second fence plate 82 are provided on both sides of the synchronous belt 72. The first fence plate 81 and the second fence plate 82 constitute a fence frame; the linear reciprocating motion mechanism drives the connecting rod 83 to swing left and right, driving the fence frame to swing left and right, so that the row of plastic ampoules 11 also swing left and right during the process of moving forward, so that the medicine liquid oscillates in the row of plastic ampoules, so that the medicine liquid can enter the head of the row of plastic ampoules.

[0054] The linear reciprocating motion mechanism is composed of a connecting rod 86, an eccentric shaft 87, and a motor 88; one end of the connecting rod 86 is hinged to the connecting rod 83, and the other end is hinged to the eccentric shaft 87; the eccentric shaft 87 is connected to the motor 88. Figure 1 As shown, the connecting rod 86 is hinged on the vertical hinge shaft on the connecting rod 83, and the other end is hinged on the eccentric shaft 87; when the motor 88 drives the eccentric shaft 87 to rotate, it drives the connecting rod 86 to produce a push-pull motion, thereby driving the connecting rod 83 to swing.

[0055] There is a gap between the first fence plate 81 and the second fence plate 82; the width of the gap is greater than the outer diameter of the push rod 73 on the synchronous belt 72. Since the push rod 73 needs to push the row of plastic ampoules to move, a gap needs to be left between the fence frames for the push rod 73 to move.

[0056] In order to improve the pushing stability of the fence frame on the row of plastic ampoules, the cross-sections of the first fence plate 81 and the second fence plate 82 are L-shaped.

[0057] In order to improve the stability of the movement of the connecting rod 83 , the connecting rod 83 is arranged on the guide rail 84 through a slider 85 .

[0058] Then it passes through the head detection station 9, and the head detection emitter probe 15 is arranged at the upper and lower positions of the head detection station 9. The head detection emitter probe 15 cooperates with the head detection receiver 16 to ensure that the surface of the front half of the head is completely inspected in turn. Then it passes through the tail detection station 10, and the tail detection emitter probe 21 cooperates with the tail detection receiver 22 to complete the inspection of the lower part of the tail.

[0059] like Figure 8 , which is a schematic structural diagram of the tail detection emitter probe 21. The tail detection emitter probe 21 is arranged horizontally. When the row of plastic ampoules 11 moves past, the end of the tail detection emitter probe 21 contacts the tail of the row of plastic ampoules 11 for detection.

[0060] Then, the second flipping mechanism 19 is used to turn the upper and lower surfaces of the row of plastic ampoules over, and then the second group of head inspection stations 9 are used to complete the surface inspection of the rear part of the head (after flipping, this part of the surface is forward). When passing through the second group of tail inspection stations 2, the upper part of the bottle tail (which becomes the lower part after flipping and contacts the drug solution) is inspected.

[0061] After the test is completed, according to the test results, the scrapping mesh belt 20 is controlled to shave the scrap. When shaving, the scrapping mesh belt 20 rotates forward a certain angle to allow the scrap to fall under the scrapping mesh belt, and the qualified products are transported backward through the scrapping mesh belt. The entire test result is completed.

[0062] Among them, the first detection mesh belt 3 and the second detection mesh belt 18 are both composed of a support plate 34 and a conveyor belt 35, and a shift rod 41 is distributed on the conveyor belt 35; the support plates 34 are distributed on both sides of the conveyor belt 35; the row of plastic ampoules slides on the support plate 34, and when the conveyor belt 35 is running, the corresponding row of plastic ampoules is pushed forward by the shift rod 41.

[0063] like Figure 11 、 12 As shown, the structure of the first flip mechanism and the second flip mechanism is as follows: they include two coaxially arranged synchronously rotating flip wheels 38; the two flip wheels 38 are arranged opposite to each other in the air; a first detection mesh belt or a second detection mesh belt for pushing the row of plastic ampoules is provided between the two flip wheels 38; a shifting rod 41 is provided on the first detection mesh belt or the second detection mesh belt; an equal number of flip blades 46 for flipping the row of plastic ampoules are provided in a circular array on the wheel surface of the flip wheel 38; the flip blades 46 on the two flip wheels 38 are arranged in a one-to-one correspondence.

[0064] The flip blade 46 consists of two parallel sub-blades 461. The gap between the two sub-blades 461 on the same flip blade 46 forms a cavity 462 for accommodating the row of plastic ampoules. The gap between the two sub-blades 461 should be larger than the thickness of one row of plastic ampoules but smaller than the thickness of two row of plastic ampoules, ensuring that only one row of plastic ampoules can be accommodated at a time.

[0065] A driving shaft 32 connected to the flip motor 51 is set at the center of the back of one of the flip wheels 38; a driven shaft 42 is set at the center of the back of the other flip wheel 38; the driving shaft 32 and the driven shaft 42 are installed on the corresponding mounting plates 40 on both sides; a first pulley 36 is set on the driving shaft 32 and the driven shaft 42; a transmission shaft 49 parallel to the driving shaft 32 is set between the mounting plates 40; a second pulley 47 corresponding to each first pulley 36 is set on the transmission shaft 49; a first synchronous belt 39 is set between the first pulley 36 and the second pulley 47.

[0066] In order to enable the shifting rod 41 to move between the flipping wheels 38 , in a preferred embodiment, the distance between the two flipping wheels 38 is larger than the outer diameter of the shifting rod 41 .

[0067] Support plates 34 for supporting the rows of plastic ampoules are provided on both sides of the conveyor belt 35 ; the turning wheel 38 is located between the two support plates 34 .

[0068] The row of plastic ampoules moves on the support plate 34 and is pushed forward by the lever 41 on the detection mesh belt. The tail of the ampoule moves forward and enters the flip wheel 38. The flip blade 46 of the flip wheel 38 holds the row of plastic ampoules and rotates clockwise, so that the head of the row of plastic ampoules faces forward and walks out of the flip mechanism, realizing a 180° flip of the continuous medicine (the head can also face forward and the tail faces forward), and then continues to fall onto the support plate 34 and continues to be pushed forward by the push rod 73.

[0069] It should be noted that, in this article, the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements that are inherent to such process, method, article or apparatus.

[0070] This article uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only used to help understand the method of the present invention and its core ideas. The above is only a preferred implementation method of the present invention. It should be pointed out that due to the limitations of textual expression, there are objectively infinite specific structures. For ordinary technicians in this technical field, without departing from the principles of the present invention, they can make several improvements, modifications or changes, and can also combine the above technical features in an appropriate manner; these improvements, modifications, changes or combinations, or the direct application of the inventive concept and technical solution to other occasions without improvement, should be regarded as the scope of protection of the present invention.
