DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model; it is obvious that the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the utility model without making creative work are within the scope of protection of the utility model.

[0023] Example:

[0024] See also Figure 1-Figure 4 As shown, a high-precision eye drop filling device includes a workbench 1, a back plate 2 is vertically arranged on the rear side of the upper surface of the workbench 1, the back plate 2 is in an inverted L shape, the top of the back plate 2 extends forward, a liquid storage cylinder 3 is installed on the top of the back plate 2, so that the liquid storage cylinder 3 is in a suspended state, a slide groove 21 is vertically opened on the front side surface of the back plate 2, an I-shaped lifting plate 7 is vertically slidably installed inside the slide groove 21, and the I-shaped structure can ensure that it can only slide up and down along the slide groove 21, a lifting cylinder 17 is fixed on the upper part of the slide groove 21, and the output end of the lifting cylinder 17 is downwardly installed On the I-shaped lifting plate 7, the lifting cylinder 17 is used to control the up and down movement of the I-shaped lifting plate 7. An extension plate 8 is arranged on the front side of the I-shaped lifting plate 7. A filling head 9 is vertically installed on the surface of the extension plate 8. The bottom of the filling head 9 is conical and its diameter is larger than the bottle mouth. When it is in a long-closed state, when it moves down and is squeezed by the bottle mouth, the inside of the filling head 9 opens, so that the medicine flows downward into the empty bottle. A hose 10 is connected to the top of the filling head 9, and the end of the hose 10 away from the filling head 9 is connected to the bottom of the liquid storage cylinder 3 to guide the medicine inside the liquid storage cylinder 3 to the inside of the filling head 9.

[0025] Among them, a turntable 4 is rotatably installed on the upper surface of the workbench 1, and placement grooves 5 adapted to empty bottles are evenly opened on the upper surface of the turntable 4, so that the empty bottles can be limited by the placement grooves 5 to ensure the stability of the empty bottles when moving, which is convenient for accurate docking. Grooves 6 are evenly opened on the outer surface of the turntable 4, and multiple grooves 6 correspond to multiple placement grooves 5 one by one. When the placement grooves 5 of the rotating turntable 4 rotate to the rearmost end, the corresponding grooves 6 are also placed on the rearmost side and open backwards. A positioning hole 61 is opened inwardly at the center of the groove 6, and both sides of the groove 6 are provided with inclined surfaces with the center concave inward. When the sliding bolt 12 is pushed forward, the turntable 4 can be fine-tuned through the inclined surfaces of the groove 6 to adjust the position of the empty bottle at the rear side.

[0026] Please refer to Figure 2 , Figure 3 and Figure 5 As shown, an installation cavity 11 is opened at the lower part of the back plate 2, and a sliding bolt 12 is horizontally slidably installed inside the installation cavity 11. The sliding bolt 12 passes through the front surface of the back plate 2. The sliding bolt 12 is adapted to the inner size of the positioning hole 61. The turntable 4 is fixed by the cooperation of the two. An arc surface 121 is provided at the end of the sliding bolt 12 to facilitate guiding the docking.

[0027] Among them, a sliding rod 13 is vertically slidably installed on the lower surface of the inner part of the sliding groove 21, and the bottom of the sliding rod 13 is placed above the inside of the installation cavity 11. A connecting rod 14 is installed on the bottom of the sliding rod 13 through a pin shaft. The end of the connecting rod 14 away from the sliding rod 13 is installed at the rear end of the sliding bolt 12 through a pin shaft. The connection direction of the connecting rod 14 ensures that when the sliding rod 13 moves downward, it can drive the sliding bolt 12 to slide forward, so as to automatically fix the turntable 4.

[0028] Please refer to Figure 5 As shown, an adjusting pressure head 15 is installed on the top of the slide bar 13 through a threaded engagement, and the height of the adjusting pressure head 15 can be adjusted to ensure that when the I-shaped lifting plate 7 moves downward, the adjusting pressure head 15 is moved downward first, and when the end of the sliding bolt 12 enters the inside of the positioning hole 61, the bottom of the filling head 9 is docked with the bottle mouth to ensure the consistency of the two. The adjusting pressure head 15 is placed directly below the I-shaped lifting plate 7, and a spring 16 is sleeved on the surface of the slide bar 13. The top of the spring 16 contacts the lower surface of the adjusting pressure head 15, and the bottom of the spring 16 contacts the lower surface of the inside of the slide groove 21, so as to utilize the elastic force of the spring 16 to place the adjusting pressure head 15 at the top when no force is applied. At this time, the sliding bolt 12 is placed at the rearmost side and will not hinder the rotation of the turntable 4.

[0029] Working principle: first, place the empty bottle inside the placement slot 5 at the front side to keep it fixed. At this time, the mouth of the empty bottle faces upward. Due to the existence of the spring 16, the adjustment pressure head 15 is placed at the top of the stroke. At this time, the sliding bolt 12 is pulled backward by the connecting rod 14, which will not affect the rotation of the turntable 4. Then, the turntable 4 is rotated to place the unfilled empty bottle directly under the filling head 9. Then, the lifting cylinder 17 controls the I-shaped lifting plate 7 to move downward, so that the I-shaped lifting plate 7 gradually moves downward, so that the filling head 9 is connected to the bottle mouth. At the same time, the I-shaped lifting plate 7 can be adjusted. The pressure head 15 is pressed to make the slide bar 13 move down, and then the slide bolt 12 is pushed forward by the connecting rod 14. At this time, the turntable 4 can be corrected by the inclined surfaces on both sides of the groove 6. The slide bolt 12 is continuously pushed forward. When the empty bottle is completely aligned with the filling head 9, the end of the slide bolt 12 is placed in the slide groove 21 on the rear side to keep the turntable 4 fixed. Conversely, after the filling is completed, the I-shaped lifting plate 7 moves up, and the slide bolt 12 is disengaged from the groove 6. At this time, the turntable 4 can be rotated to rotate the filled bottle to the front to facilitate loading and unloading.

[0030] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
