Description

Technical Field

[0001] The utility model belongs to the technical field of syringe production, and in particular relates to a flip-type clamping module. Background Art

[0002] In the production process of syringes, in order to meet the requirements of dust-free and sterile standards, the syringes need to be cleaned and sterilized after production. In order to reduce labor costs and improve work efficiency, disc-type grippers are often used to grab the syringes on the automatic loading tray and then rotate them to the cleaning area for rinsing and cleaning. The cleaned syringes are then placed on the automatic unloading tray. However, both the automatic loading tray and the unloading tray require the opening of the syringe to face upward. However, if the syringe is directly rinsed and cleaned after grabbing it, the water will flow slowly due to the downward position of the needle tip, and the water in the syringe barrel cannot be quickly discharged in time, resulting in low production efficiency. In order to solve such problems, a flip gripper module is proposed. Utility Model Content

[0003] The utility model aims to solve at least one of the technical problems existing in the prior art.

[0004] To this end, the utility model provides a flip-type gripping module, which has the advantage of being able to adjust the direction of the syringe to facilitate cleaning of the syringe.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] The flip-type gripping module of the present utility model will be described in detail below with reference to the accompanying drawings.

[0026] like Figure 1-Figure 3As shown, the flip-type gripping module according to the embodiment of the utility model includes: a turntable, a clamping unit 21, a guide block 24, and two limit plates 28; the clamping unit 21 is rotatably connected to the turntable, and the turntable is used to drive the clamping unit 21 to rotate along the circumferential direction of the turntable. A guide rod 26 is provided at one end of the clamping unit 21, and the middle of the guide rod 26 is fixedly connected to the clamping unit 21. The guide block 24 faces the guide rod 26. When the turntable drives the clamping unit 21 to pass through the guide block 24, the guide block 24 changes the movement direction of the guide rod 26, so that the guide rod 26 drives the clamping unit 21 to flip, and the two limit plates 28 are respectively located on both sides of the guide block 24 along the movement direction of the clamping unit 21, and the limit plates 28 are used to limit the angles of the guide rod 26 before and after flipping.

[0027] In this embodiment, the clamping unit 21 includes a connecting shaft 22, and the connecting shaft 22 is connected to the turntable by a fixed block 23. The fixed block 23 is fixedly connected to the turntable, and the fixed block 23 is rotatably connected to the connecting shaft 22. One end of the connecting shaft 22 is fixedly connected to the guide rod 26. The turntable drives the clamping unit 21 to rotate to grab the syringe on the loading disk. At this time, the syringe on the clamping unit 21 is in an open upward state. During the rotation of the clamping unit 21, it is limited by a limit plate 28. At this time, the clamping unit 21 is always in a horizontal state to facilitate grabbing the syringe. When the clamping unit 21 passes through the guide block 24, the guide block 24 toggles the guide rod 26, and the guide rod 26 loses the limit of a limit plate 28 as it is toggled, thereby realizing the flipping effect of the clamping unit 21. After flipping, The clamping unit 21 drives the syringe into the cleaning area for cleaning. After the clamping unit 21 is flipped, another limit plate 28 continues to limit the guide rod 26 to prevent the clamping unit 21 from rotating during the subsequent movement, thereby ensuring the stability of the subsequent clamping unit 21 for subsequent cleaning operations. By setting the clamping unit 21 to be rotatably connected with the turntable, it is convenient to flip the clamping unit 21, so that the clamping unit 21 is easy to match the loading disc and the unloading disc, which is also beneficial to the cleaning of the syringe and the outflow of water in the syringe from the opening, thereby speeding up the cleaning speed. By setting the limit plates 28 on both sides of the guide block 24, the failure of grabbing the syringe due to the tilt of the clamping unit 21 is avoided, thereby ensuring the angle of the working state of the clamping unit 21.

[0028] The middle of one side of the guide rod 26 is connected to the clamping unit 21 , and guide posts 27 are provided at both ends of the other side of the guide rod 26 ; the guide block 24 is formed with a guide groove 25 along the moving direction of the clamping unit 21 , and the guide groove 25 is used to change the moving direction of the guide post 27 .

[0029] The middle of the guide groove 25 is convex upward, and a clamping groove 251 is formed on the upper surface of the middle of the guide groove 25. When a guide column 27 enters the middle position of the guide groove 25, the distance from the upper surface of the guide column 27 to the center of the guide rod 26 is greater than the protruding height of the guide groove 25.

[0030] When the two guide pillars 27 pass through the limiting plate 28 at the same time, the upper surfaces of the two guide pillars 27 are in contact with the lower surface of the limiting plate 28 .

[0031] The distance between the central axes of the two guide pillars 27 is greater than the distance between the limiting plate 28 and the guide block 24 .

[0032] The heights of both ends of the guide groove 25 are the same as the heights of the guide pillars 27 limited by the limiting plates 28 .

[0033] In this embodiment, the limit plate 28 is connected to the guide block 24. Under the limit of one limit plate 28, one guide post 27 directly enters one end of the guide groove 25 when passing through the guide block 24. At this time, the guide rod 26 that continues to rotate continues to push one guide post 27 to move into the guide groove 25. Since the guide groove 25 is inclined upward, under the height restriction of the turntable, the other end of the guide rod 26 rotates downward at this time. However, due to the length restriction of the guide rod 26, the guide rod 26 is still in an inclined state until the turntable drives one guide post 27 to be located in the middle position of the guide groove 25. 7 slides into the slot 251. At this time, the guide rod 26 is in a vertical state. The turntable continues to drive the guide rod 26 to move. At this time, due to the length limitation of the guide rod 26, one guide post 27 is stuck in the slot 251, and the other guide post 27 moves with the turntable first, until one guide post 27 slides out of the slot 251. As the guide slot 25 is curved downward, one guide post 27 gradually moves downward, pushing the other guide post 27 gradually upward, until one guide post 27 contacts the lower surface of the other limit plate 28. At this time, the guide rod 26 drives the clamping unit 21 to complete a 180-degree flip.

[0034] The guide post 27 is a roller, through which the guide post 27, the guide groove 25 and the limit plate 28 are all rollingly connected, reducing friction, avoiding jamming, and achieving smooth movement. The gap between the roller and the guide groove 25 and the clamping groove 251 is 0.15mm-0.25mm.

[0035] The guide groove 25 and the clamping groove 251 are smoothly connected to facilitate the cutting-in of the guide post 27 and avoid the phenomenon of jamming.

[0036] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "illustrative embodiments", "examples", "specific examples", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model.
