The initial position of the sleeve holes 25 is concentric with the syringe. When the hydraulic pressure in the syringe increases, the push rod of the syringe will be pushed outward, so that the push rod enters the sleeve hole 25. At this time, the motor 7 starts to drive the gear 11 to rotate left and right, thereby driving the rack 10 to move up and down. At this time, the sleeve hole 25 drives the push rod of the syringe to swing up and down, so as to further detect the sealing inside the syringe.

[0051] One side of the support plate 5 is fixed to two groups of limit rods, and a connecting rod 8 is slidably connected to the limit rod. The connecting rod 8 is fixedly connected to the lifting plate 9, and plays a stabilizing role when the lifting plate 9 is raised or lowered.

[0054] The sealing detection system includes a control module and a logic judgment module.

[0055] The infusion control submodule includes a time recording unit.

[0056] The logic judgment module includes a photo receiving submodule, a hydraulic receiving submodule, an analysis submodule and a marking submodule. The photo receiving submodule is electrically connected to the camera 17 , and the hydraulic receiving submodule is electrically connected to the hydraulic gauge 13 .

[0057] The seal detection system includes the following methods of use:

[0058] Method 1: Pass the syringe through the ferrule 12, and fix the syringe by the cooperation between the ferrule 12 and the fixing seat 23;

[0059] It should be noted that the initial state of the syringe when it is fixed by the fixing assembly is a contracted state.

[0060] Method 2: Start the pressing assembly to drive the pressing plate 16 to move downward, press the surface of the syringe for a period of time and then move upward to determine whether the surface of the syringe is deformed when subjected to pressure;

[0061] Specifically, the camera 17 takes a picture of the syringe surface and transmits it to the picture receiving submodule to analyze whether the syringe surface is deformed. If it is deformed, the signal is transmitted to the marking submodule for recording.

[0062] Method three: Start the filling component and pour the liquid in the liquid storage tank 1 into the syringe. When the hydraulic pressure in the syringe increases, it will push the piston in the syringe to move outward until the syringe push rod stroke ends and the filling component stops working. At this time, the end of the syringe push rod extends into the sleeve hole 25, and the hydraulic gauge 13 detects the pressure of the connecting sleeve 21 and transmits it to the hydraulic receiving submodule to determine the sealing of the syringe;

[0063] Method 4: When the syringe sealing test is completed and the syringe needs to be removed, the surface of the syringe can be cleaned through the ring 12 to ensure that the surface of the syringe is clean.

[0064] Method 3 includes the following specific steps:

[0065] Method 3-a: When the syringe push rod is pushed, the time recording unit starts timing, and the timing ends when the syringe push rod reaches the end of its travel. At this time, the analysis submodule analyzes the time when the syringe push rod moves to determine whether there is liquid leakage when the syringe push rod moves;

[0066] Specifically, under normal circumstances, the time required for the syringe push rod to be pushed by the hydraulic pressure until the end of the stroke is t. When the actual time required for the syringe push rod is compared with the set time t, if they are consistent, it means that there is no leakage when the syringe push rod moves. If the time is inconsistent, it means that the syringe has a leak, causing the internal hydraulic pressure to become insufficient to push the syringe push rod into the sleeve hole 25 according to the set time. At this time, the staff will remove the syringe that is leaking liquid.

[0067] Method 3-b: When there is no leakage during the movement of the syringe push rod, the liquid is allowed to stand in the syringe for a period of time, and the hydraulic pressure on the connecting sleeve 21 is detected by the hydraulic gauge 13 and the data is transmitted to the hydraulic receiving submodule to further determine the sealing of the syringe;

[0068] Specifically, a constant hydraulic value r is set in the hydraulic receiving submodule. When the liquid is left standing in the syringe, if the hydraulic value does not change, it means that the liquid in the syringe is not leaking. If the hydraulic pressure decreases, it indicates that the liquid in the syringe is leaking, and the staff removes the syringe.

[0069] It should be noted that when the staff removes the syringe that leaks liquid, the valve control submodule starts the electric control valve 20 to close, blocking the connecting tube 24 between the connecting sleeves 21 to prevent the syringes from being connected in series and affecting the sealing detection.

[0070] Method 3-c: After confirming that the liquid in the syringe has not leaked after being left for a period of time, the adjustment component is activated to control the syringe push rod to swing up and down to determine whether the syringe will leak when the syringe push rod is disturbed;

[0071] Specifically, the hydraulic gauge 13 is detected in real time when the syringe push rod swings up and down. If the hydraulic gauge 13 changes compared with the constant hydraulic value r, it means that leakage occurs when the syringe push rod swings, indicating that the syringe has poor sealing. If the hydraulic gauge 13 does not change compared with the constant hydraulic value r, it means that the syringe has good sealing.

[0072] Method 3-d: When the syringe is well sealed, remove the liquid in the syringe and determine again whether the appearance of the syringe is deformed;

[0073] Specifically, after the liquid in the syringe is drawn out, the camera 17 is started again to take a photo of the surface of the syringe and transmit it to the photo receiving submodule. Since the syringe that has been deformed before the detection is recorded by the recording submodule in method two, the photo of the syringe after the detection is compared with the photo of the syringe that has been deformed before the detection. If the syringe after the detection is restored to its original shape by the pressure of the internal hydraulic pressure, it means that the appearance quality of the syringe is good. If the shape of the syringe after the detection is not restored, it indicates that the appearance quality of the syringe is poor, and the staff needs to be reminded to manually restore the syringe to its original shape.

[0074] Through the above steps, a progressive detection method is adopted to detect the sealing of the syringe from multiple angles, which can improve the detection of sealing and judge the appearance quality of the syringe, further ensuring the overall production quality of the syringe.

[0075] Method 4 includes the following specific steps:

[0076] Method 4-a: Collecting the leaked liquid in the collecting shell 26;

[0077] Method 4-b: When it is necessary to remove the syringe of good quality, start the liquid pump 29 to pump the liquid collected by the collection shell 26 into the ring 12 through the central tube 28 to soak the sponge;

[0078] Method 4-c: At this time, the staff loosens the fixing assembly and pulls out the syringe. When the syringe is pulled out, wipe the surface of the syringe with a wet sponge to ensure the cleanliness of the syringe;

[0079] Through the above steps, the inside and outside of the syringe can be kept clean after the syringe sealing is tested.

At this time, the analysis submodule analyzes the time when the syringe push rod moves to determine whether there is liquid leakage when the syringe push rod moves; Method three-b: when there is no leakage during the movement of the syringe push rod, the liquid is allowed to stand in the syringe for a period of time, and the hydraulic pressure on the connecting sleeve (21) is detected by a hydraulic gauge (13) and the data is transmitted to the hydraulic receiving submodule to further determine the sealing performance of the syringe; Method 3-c: After confirming that the liquid in the syringe has not leaked after being left for a period of time, the adjustment component is activated to control the syringe push rod to swing up and down to determine whether the syringe will leak when the syringe push rod is disturbed; Method 3-d: When the syringe is well sealed, draw out the liquid in the syringe and determine again whether the appearance of the syringe is deformed.

7. A syringe seal detection method according to claim 6, characterized in that: The method 4 comprises the following specific steps: Method 4-a: Collecting the leaked liquid in the collecting shell (26); Method 4-b: When it is necessary to remove the syringe of good quality, start the second liquid pump (29) to pump the liquid collected by the collection shell (26) into the ring (12) through the central tube (28) to soak the sponge; Method 4-c: At this time, the staff loosens the fixing assembly and pulls out the syringe. When the syringe is pulled out, wipe the surface of the syringe with a wet sponge to ensure the cleanliness of the syringe.
