[0035] The present application is further described in detail below in conjunction with the drawings and specific embodiments of the present application.

[0036] Example one

[0037] Figures 1 to 5 An embodiment of the needle filling cleaning and sterilization system of the present application is shown. The needle filling cleaning and sterilization system of the embodiment includes a cleaning and sterilization box 1 arranged in a cleaning and sterilization area and a needle filling rack 3 arranged in a filling area. The needle filling 2 is installed on the needle filling rack 3. The needle filling cleaning and sterilization system further includes a needle filling lifting mechanism 41 and a needle filling translation mechanism 42, which are used to drive the needle filling rack 3 to move from the filling area to the cleaning and sterilization area. For details, see Figure 1In the embodiment, the needle filling translation mechanism 42 includes a translation servo motor 421, the translation servo motor 421 drives a synchronous belt wheel to rotate, the needle filling frame 3 is connected with a synchronous belt arranged on the synchronous belt wheel, so that reciprocating translation can be realized, and the translation precision is high and the automatic control is facilitated by using the servo motor as the translation driving part. Correspondingly, the needle filling lifting mechanism 41 can also use a lifting servo motor 411 as the lifting driving of the needle filling frame 3, and the lifting precision is high and the automatic control is facilitated. It should be noted that the specific structure of the needle filling lifting mechanism 41 and the needle filling translation mechanism 42 is not the main innovation point of the present application, in addition to the above-mentioned synchronous belt mechanism, chain wheel mechanism, screw nut mechanism, air cylinder and the like can also be used to realize the translation and lifting movement, which will not be described here.

[0038] The needle filling cleaning and sterilizing system of the embodiment can drive the needle filling frame 3 and the needle 2 to translate through the needle filling translation mechanism 42 after the needle 2 completes filling in the filling area, so that the needle 2 is moved from the filling area to above the cleaning and sterilizing box 1 located in the cleaning and sterilizing area, and then the needle filling frame 3 and the needle 2 can be lowered through the needle filling lifting mechanism 41, so that the lower end of the needle 2 extends into the cleaning and sterilizing box 1, facilitating subsequent cleaning and sterilization of the needle 2, and the structure is simple, the degree of automation is high, and the cleaning efficiency is improved.

[0039] Further, in the embodiment, the cleaning and sterilizing box 1 is provided with a box cover plate assembly 5, the box cover plate assembly 5 is provided with a locking structure for the needle 2 to pass through and lock the needle 2, and the box cover plate assembly 5 is connected with a cover plate lifting mechanism 6. After the needle 2 is lowered to pass through the locking structure, the box cover plate assembly 5 locks the needle 2, and then the cover plate lifting mechanism 6 drives the box cover plate assembly 5 and the needle 2 to finely adjust the height as a whole, so that the needle 2 presses the sealing element 11 (such as an O-shaped sealing ring, an inflatable sealing ring, etc.) in the cleaning and sterilizing box 1, which can ensure the sealing between the needle 2 and the cleaning and sterilizing box 1 on the one hand, prevent steam leakage during sterilization, and on the other hand, compared with the needle 2 being directly lowered by the needle filling lifting mechanism 41 to press the sealing element 11, it is beneficial to ensure the movement precision and avoid the problems of steam leakage due to insufficient pressing or damage of the needle 2 due to excessive pressing (since the lifting stroke of the needle filling lifting mechanism 41 is large and fast, and the cover plate lifting mechanism 6 only needs to finely adjust the height of the box cover plate assembly 5, so the cover plate lifting mechanism 6 can reliably press the sealing element 11 of the needle 2).

[0040] Further, in the embodiment, the outer wall of the filling needle 2 is provided with a clamping groove 21, the box cover plate assembly 5 comprises a movable cover plate 51, the locking structure comprises a first passing part 511 provided on the cover plate 51 for the filling needle 2 to pass through and a clamping part 512 for clamping the clamping groove 21, and the first passing part 511 is connected with the clamping part 512. The lower end of the filling needle 2 descends through the first passing part 511 until the clamping groove 21 is located in the first passing part 511, and then the descending is stopped. Then the cover plate 51 is moved so that the clamping part 512 clamps the clamping groove 21, the filling needle 2 is locked with the cover plate 51, and the subsequent height adjustment of the filling needle 2 with the cover plate 51 is facilitated. The structure is reasonable and effective. After the cover plate 51 is reversely moved and reset, the clamping groove 21 is located in the first passing part 511 again, and the filling needle 2 can be lifted and separated from the cover plate 51.

[0041] As a preferred embodiment, the clamping groove 21 is an annular groove, and the first passing part 511 and the clamping part 512 are both arc-shaped. Since the clamping groove 21 adopts the annular groove, the installation angle of the filling needle 2 is not required, and the clamping part 512 can clamp the clamping groove 21. The first passing part 511 and the clamping part 512 adopt the arc-shaped structure, which is convenient for adapting to the annular groove, has good stress balance, and has a simple and effective structure. Of course, in other embodiments, the clamping groove 21 can be provided on one side or opposite sides of the filling needle 2, and needs to be installed at a correct angle when installed on the filling needle frame 3.

[0042] Further, in the embodiment, the box cover plate assembly 5 further comprises a bottom plate 52 and a cover plate driving member 53 (such as a pneumatic cylinder, an electric push rod, etc.) for driving the cover plate 51 to move, the bottom plate 52 is provided with a guide part 521 for guiding the cover plate 51 and a second passing part 522 for the filling needle 2 to pass through, the cover plate driving member 53 is arranged on the bottom plate 52, and the cover plate lifting mechanism 6 is connected with the bottom plate 52. The lower end of the filling needle 2 descends through the first passing part 511 and the second passing part 522 on the bottom plate 52 until the clamping groove 21 is located in the first passing part 511, and then the descending is stopped. Then the cover plate driving member 53 drives the cover plate 51 to move so that the clamping part 512 clamps the clamping groove 21. On one hand, the guide part 521 can provide a guiding effect for the movement of the cover plate 51, ensure the movement accuracy, and avoid deviation. On the other hand, the guide part 521 can prevent the cover plate 51 from moving upward relative to the bottom plate 52. Then the cover plate lifting mechanism 6 drives the cover plate 51 and the filling needle 2 to descend for height adjustment through the bottom plate 52. The structure is reasonable and effective.

[0043] Further, in the embodiment, the cover plate driving member 53 is arranged at one end of the bottom plate 52, and the other end of the bottom plate 52 is provided with a locking-in-place detection member 54 (such as various sensors, travel switches, etc.) for detecting whether the cover plate 51 is locked in place. After the locking-in-place detection member 54 detects that the cover plate 51 is in place, the clamping part 512 clamps the clamping groove 21 at this time, and the cover plate driving member 53 stops moving to ensure the reliability of the locking structure.

[0044] Further, in the embodiment, the cover plate lifting mechanism 6 comprises a lifting driving member 61 (for example, a pneumatic cylinder, an electric push rod, etc.), a connecting member 62, and a compression-to-position detection member 63 (for example, various sensors, travel switches, etc.) for detecting whether the box cover plate assembly 5 is compressed to position. The lifting driving member 61 is connected with the box cover plate assembly 5 (specifically, the bottom plate 52) through the connecting member 62. When the compression-to-position detection member 63 detects that the box cover plate assembly 5 (preferably, the bottom plate 52) is compressed to position, the filling needle 2 compresses the sealing member 11 at this time, and the lifting driving member 61 stops working, which is beneficial to ensure the sealing between the filling needle 2 and the cleaning and sterilizing box 1, prevent the filling needle 2 from being damaged due to excessive compression, and improve the reliability and the automation and intelligence level.

[0045] As a preferred embodiment, the connecting member 62 is in a U-shaped groove structure, the cleaning and sterilizing box 1 is located in the middle of the connecting member 62, and the box cover plate assembly 5 is connected with the connecting member 62 at both sides, so that the overall structure is compact and occupies less space, and the stress balance of the two sides of the box cover plate assembly 5 is ensured.
