[0026] Embodiment:

[0027] As Figures 1-2 The utility model provides a row of plastic ampoule leak detection device, including: support subassembly, the support subassembly one side is the bottle end 01, the other side is the bottle end 02, including first guide rail 1 and second guide rail 2, first guide rail 1 and second guide rail 2 are arranged in the leak detection device both sides of the application, and the detection space between first guide rail 1 and second guide rail 2, the inner side of first guide rail 1 is provided with the outwardly convex outer convex part 11, the outer convex part 11 with first guide rail 1 is the integral structure through processing, the inner side of second guide rail 2 is provided with the inwardly recessed inner recess 21, the inner recess 21 with second guide rail 2 is the integral structure through processing, and the inner side of first guide rail 1 and the inner side of opposite second guide rail 2 are mutually parallelly arranged;Power assembly, the power assembly is used to drive row ampoule 7 from the bottle end 01 to the bottle end 02, including the gear teeth 3 of contact with row ampoule 7 and the driving part 4 connected with gear teeth 3, the power assembly is installed between first guide rail 1 and second guide rail 2, and the driving part 4 is belt drive or chain drive, the driving part 4 drives gear teeth 3, and gear teeth 3 drives row ampoule 7 to move forward, preferably, a plurality of gear teeth 3 are arranged at equal intervals in the driving part 4 to realize continuous detection;Detection assembly, the detection assembly includes two groups of electrodes arranged on first guide rail 1 and / or second guide rail 2, wherein the first electrode group 5 is arranged at the bottle end 01 or the bottle end 02, and the second electrode group 6 is arranged at the position of inner recess 21 or outer convex part 11, and the first electrode group 5 and the second electrode group 6 are connected with power supply through line. It needs to point out that the inner side in the application is all the side close to power assembly, and the outer side is all the side away from power assembly, and the upper surface is all the side close to detection assembly, which will not be described below.

[0028] By the above setting, when the row of ampoules 7 passes through the outer convex part 11 and the inner recessed part 21, the movement trajectory of the row of ampoules 7 changes from a straight line to a curved line, without the need to adjust the structure and position of the power assembly, so that the row of ampoules 7 is laterally displaced compared to the driving part 4, the contact position of the racking teeth 3 with the row of ampoules 7 is changed, and then the second electrode group 6 is arranged at the position of the inner recessed part 21 or the outer convex part 11, so as to solve the problem of detection blind area of the racking teeth 3 position in the leakage detection process in the prior art. The leakage detection device provided by the application further improves the detection precision and reduces the installation and maintenance difficulty under the premise of realizing continuous detection and ensuring the detection efficiency. And by arranging the inner side surface of the first guide rail 1 and the inner side surface of the second guide rail 2 in parallel, the stability of the row of ampoules 7 during movement is ensured, the risk of falling of the row of ampoules 7 is reduced, and the detection efficiency is further improved.

[0029] Specifically, as shown in Figures 1-5 The inner side of the first guide rail 1 is provided with a first guide table 8 for supporting one end of the row of ampoules 7, and the inner side of the second guide rail 2 is provided with a second guide table 9 for supporting the other end of the row of ampoules 7. The inner side surface of the first guide table 8 is parallel to the inner side surface of the first guide rail 1, and the inner side surface of the second guide table 9 is parallel to the inner side surface of the second guide rail 2. Through the above arrangement, when the row of ampoules 7 twists and jams during transportation and tends to fall off, the inner side surface of the first guide table 8 and the inner side surface of the first guide rail 1, and the inner side surface of the second guide table 9 and the inner side surface of the second guide rail 2 can limit the tail side, head side and downward protruding part of the row of plastic ampoules, effectively preventing the row of ampoules 7 from falling off and further improving the transportation stability. Preferably, the distance from the inner side surface of the first guide table 8 to the inner side surface of the first guide rail 1 and the distance from the inner side surface of the second guide table 9 to the inner side surface of the first guide rail 1 can be set according to the width of the plastic connecting piece at the tail and head of the row of plastic ampoules 7 for actual leakage detection operation, so as to ensure better transportation stability.

[0030] Specifically, as shown in Figures 1-2As shown, the first electrode group 5 is arranged on the first guide rail 1, and the second electrode group 6 is arranged on the second guide rail 2. The first electrode group 5 is used to detect a part of the arrayed ampoule 7, and the second electrode group 6 is used to detect another part of the arrayed ampoule 7. In the embodiment, the first electrode group 5 is detachably connected to the first guide rail 1 near the bottle inlet end 01 by a support, and the second electrode group 6 is detachably connected to the inner recessed part 21 of the second guide rail 2 by a support. It should be noted that, according to the installation position and the convenience of wiring, the first electrode group 5 can also be arranged at the outer protruding part 11, and the second electrode group 6 can be arranged at the position near the bottle inlet end 01 of the second guide rail 2 or the position near the bottle outlet end 02 of the second guide rail 2. Through the above arrangement, the problem of electrode group deformation leading to detection misalignment in the use process is avoided, and the cost is saved, and the detection blind area is ensured. Preferably, the first electrode group 5 and the second electrode group 6 are arranged by a plurality of electrode needle arrays symmetrically upward and downward. In the use process, the electrode needles can be increased or decreased according to the size and model of the arrayed ampoule 7 to be detected to ensure that there is no detection blind area.

[0031] Specifically, as shown in Figures 2-3 The surface of the inner recessed part 21 is arranged as a recessed plane 211, and the both ends thereof are smoothly transitioned to the second guide rail 2 through inclined surfaces 212. It can be understood that the inner side surface of the first guide rail 1 and the inner side surface of the second guide rail 2 are arranged in parallel, and therefore the surface of the outer protruding part 11 is arranged as a protruding plane 211, and the both ends of the plane 211 are smoothly transitioned to the first guide rail 1 through inclined surfaces 212. Through the above arrangement, when the arrayed ampoule 7 is conveyed through the inclined surface 212, the arrayed ampoule 7 is laterally displaced, and at this time, the ratchet 3 slides on the arrayed ampoule 7, which is more likely to cause the liquid in the arrayed ampoule 7 to shake. By arranging the surface of the inner recessed part 21 as a plane 211 with a certain length, the arrayed ampoule 7 moves stably, which can stabilize the liquid in the arrayed ampoule 7 and avoid affecting the detection precision due to the shaking of the liquid. Preferably, as shown in Figure 3As shown in the figure, the angle a between the plane 211 of the inner recess 21 and the two side slopes 212 ranges from 3° to 5°. The above parameters are very critical. If a is less than 3° or greater than 5°, the relationship between the overall size of the leak detection device and the transverse movement distance of the row of ampoules 7 cannot be coordinated. For example, when a is less than 3°, the slope 212 needs to be set too long to ensure that the transverse movement distance of the row of ampoules 7 is sufficient to eliminate the detection blind area caused by the pawl 3, which will result in the size of the leak detection device being too large. When a is greater than 5°, although the structure of the leak detection device can be compact, the stable conveying of the row of ampoules 7 cannot be guaranteed, which is prone to shaking and jamming. Only when a ranges from 3° to 5°, can the structure of the leak detection device be compact, the movement be stable, and the space occupied be small without detection blind area.

[0032] Specifically, as shown in the figure, Figure 3 The length H of the slope 212 and the angle a satisfy the following relationship: H = -38.5a + 303, and the unit of length H is mm. It can be seen that under the premise of ensuring no detection blind area, the length H of the slope 212 gradually shortens with the increase of the angle a, which further ensures the stable conveying of the row of ampoules 7 and controls the overall size of the leak detection device, thereby reducing the production cost.

[0033] Specifically, as shown in the figure, Figures 4-5 The vertical distance L0 from the upper surface to the bottom of the first guide 8 at the position of the first electrode group 5 is less than the vertical distance L1 from the upper surface to the bottom of the second guide 9 at the position of the first electrode group 5; the vertical distance L3 from the upper surface to the bottom of the second guide 9 at the position of the second electrode group 6 is less than the vertical distance L4 from the upper surface to the bottom of the first guide 8 at the position of the second electrode group 6. It can be understood that when the row of ampoules 7 is conveyed and moved to the position of the first electrode group 5, the row of ampoules 7 is inclined to the first guide 8, so that the liquid therein fills the side to be detected for leakage close to the first guide 8. Similarly, when the row of ampoules 7 is conveyed and moved to the position of the second electrode group 6, the row of ampoules 7 is inclined to the second guide 9, so that the liquid therein fills the side to be detected for leakage close to the second guide 9. Through the above setting, the detection accuracy can be ensured and the detection error can be avoided.

[0034] Specifically, as shown in the figure, Figure 1As shown, the device further comprises a bottle pressing assembly, which comprises a first bottle pressing plate 10 arranged close to the first electrode group 5 and the second electrode group 6 and close to one side of the bottle inlet end 01, and a second bottle pressing plate 12 arranged opposite to the first electrode group 5 and the second electrode group 6, and the first bottle pressing plate 10 and the second bottle pressing plate 12 are both arranged as a rounded corner close to one side of the bottle inlet end 01. Because the plastic material row ampoule 7 is more prone to warping during transportation or production, when leak detection is performed, the leak detection row ampoule 7 is first shaped by the bottle pressing plate and then enters the electrode group for leak detection. By arranging the bottle pressing assembly, the probability of detection error caused by warping of the row ampoule 7 can be effectively reduced, and the detection accuracy is further ensured.

[0035] Specifically, the outer side of the first guide rail 1 and the outer side of the second guide rail 2 are arranged in parallel and are both arranged as a plane 211. By this arrangement, the manufacturing difficulty can be reduced, and in the daily use process, it is convenient to maintain and add accessories.

[0036] The technical features of the above-mentioned embodiments can be combined arbitrarily, and in order to make the description simple, all possible combinations of the technical features in the above-mentioned embodiments are not enumerated, however, as long as the combination of the technical features does not exist contradictory, it should be considered as the scope of the present application.

[0037] For those skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which all belong to the protection scope of the present application, and the protection scope of the present application is subject to the appended claims.
