[0031] In the conveying process, the first bottle pressing assembly 7 and the second bottle pressing assembly 8 move forward synchronously with the ampoule to be detected, and the ampoule bottle body to be detected is clamped and fixed upward and downward. First, through the above setting, high-speed leakage detection of the ampoule to be detected is realized, the problems of flying bottles and stacked bottles of the ampoule to be detected in the high-speed transmission process are solved, the detection efficiency is effectively improved, and the detection accuracy is ensured. Second, the ampoule bottle body to be detected is subjected to pressure from the first bottle pressing assembly 7 and the second bottle pressing assembly 8, so that the middle part is extruded, the internal pressure of the ampoule bottle is increased, and if there is leakage, the leakage degree can be aggravated, which is helpful to further improve the detection accuracy and avoid missed detection. Finally, through the above setting, the conveying posture can be ensured to be stable, and the forward and backward displacement of the ampoule to be detected can be avoided. In the data acquisition process, the accuracy of the data acquisition position and the continuity of the data transmission can be ensured.
[0032] Specifically, as shown in Figures 1-4 , the first bottle pressing assembly 7 and the second bottle pressing assembly 8 each comprise a guide rail 10, a conveying belt 11 wound on the guide rail 10, and a power source 12 driving the conveying belt 11 to rotate. The guide rail 10 is provided with a recessed guide groove 101, and the inner side of the conveying belt 11 is provided with a guide rib 111 matched with the guide groove 101. It should be noted that the power source 12 is driven by an electric motor or a hydraulic machine, and the electric motor driving is preferred in the present application, which will not be described in detail hereinafter. Through the above setting, the running stability of the conveying belt 11 is further enhanced, so that the ampoule bottle can be kept stable during conveying, and the posture change of the ampoule bottle caused by the deviation of the conveying belt 11 is avoided.
[0033] Specifically, as shown in Figures 1-3 , 5, the rotating lifting assembly 4 comprises a rotating lead screw 41 threadedly matched with the fixed frame 2. The upper end of the rotating lead screw 41 is connected with a hand wheel 42, and the lower end of the rotating lead screw 41 is rotatably installed in a connecting plate 43. The connecting plate 43 is connected with clamping blocks 44 installed on both sides of the guide rail 10, respectively. The rotating hand wheel 42 drives the rotating lead screw 41 to move up and down, so as to adjust the vertical height of the second bottle pressing assembly 8, and the clamping force of the ampoule bottle is easily controlled to adapt to ampoule bottles of different sizes, thereby effectively improving the applicability of the present application.
[0034] Specifically, as shown in Figure 5 , guide columns 45 are arranged on both sides of the connecting plate 43. One end of the guide column 45 is connected with the connecting plate 43, and the other end penetrates the fixed frame 2 and is fixed by a clamping block. Through this setting, the guide column 45 moves synchronously with the connecting plate 43 during the upward and downward movement of the rotating lead screw 41, which ensures the stability during adjustment and avoids the problem that the second bottle pressing assembly 8 is inclined and affects the leakage detection.
[0035] Specifically, as shown in Figure 1 ,2 As shown in Figure 6, an adjustable spacing section 13 is provided on one side of the bottle inlet end 5. The adjustable spacing section 13 is mounted on the base 1. The adjustable spacing section 13 includes at least two sets of adjustable spacing conveyor belts 131 that are adjacent to each other. The adjustable spacing conveyor belts 131 are all located on the same conveying plane and have different speeds from each other. It should be noted that the adjustable spacing conveyor belts 131 are driven by an electric motor, and their specific speed can be set according to the actual operation. In this application, the speed of the adjustable spacing conveyor belts 131 increases sequentially along the conveying direction, with the adjustable spacing conveyor belt 131 closest to the bottle inlet end 5 having the fastest speed. The above design can realize the adjustment of the ampoule spacing, so that the ampoules can maintain an appropriate spacing before entering the bottle pressing conveyor section 01, avoiding poor conveying or detection errors caused by too small a spacing.
[0036] Specifically, such as Figure 1 , 2 As shown in Figure 6, the adjustable section 13 also includes a bottle-sorting assembly. This assembly includes a connecting rod 14 horizontally positioned above the adjustable conveyor belt 131. The connecting rod 14 is detachably connected to both sides of the base 1. Two bottle-sorting plates 15 and a guide plate 16 located between the two bottle-sorting plates 15 are provided on the connecting rod 14. The extending directions of the bottle-sorting plates 15 and the guide plate 16 are consistent with the traveling direction of the adjustable conveyor belt 131. This design can organize the arrangement of ampoules, ensuring they remain neatly arranged before entering the bottle-pressing conveyor section 01. This ensures stable ampoule conveying posture and helps ensure the ampoules smoothly pass through the leak detection station 9, further improving detection accuracy and data transmission continuity. Furthermore, the surface of the connecting rod 14 is provided with graduation lines, and both the bottle-sorting plates 15 and the guide plate 16 are movably mounted on the connecting rod 14 using locking nuts 17. When testing ampoules of different sizes, simply loosen the locking nut 17, then adjust the positions of the ampoule feeder 15 and guide plate 16 according to the size of the ampoule to be tested, referring to the scale lines, and finally tighten the locking nut 17. This design allows for easy adjustment of the positions of the ampoule feeder 15 and guide plate 16 to accommodate ampoules of different sizes, reducing adjustment difficulty, improving work efficiency, and further enhancing applicability.
[0037] Specifically, such as Figure 7As shown, the distance from the end of the first pressure bottle assembly 7 to the distance adjusting part 13 is less than the distance from the second pressure bottle assembly 8 to the distance adjusting part 13, and the guide plate 16 is at least partially located above the first pressure bottle assembly 7. This design can ensure that the ampoule bottle can smoothly transition before entering the pressure bottle conveying part 01, avoiding changes in the posture of the ampoule bottle due to sudden changes in conveying speed. At the same time, the end of the first pressure bottle assembly 7 is connected with a connecting plate 18, and the end of the connecting plate 18 close to the distance adjusting part 13 is set to adapt to the arc shape of the distance adjusting conveying belt 131. This design helps to shorten the distance between the first pressure bottle assembly 7 and the distance adjusting part 13, and helps to reduce the impact and shaking of the ampoule bottle during conveying, further ensuring the smooth transition of the ampoule bottle.
