They are mainly used in scenarios such as nucleic acid reagent kit production, drug development, and cell therapy. They can realize the dispensing of deep well plates and enzyme-linked immunosorbent assay (ELISA) plates in batches. They are mainly composed of core modules such as peristaltic pumps and dispensing nozzles. However, existing automated dispensing devices for reagent kit production generally have the problem that the spacing and height of the dispensing nozzles cannot be adjusted.

[0024] Example:

[0025] Please combine Figures 1-3 An automatic dispensing device for reagent kit production according to this embodiment includes a control box 1. A first slide rail 14 is installed on one side of the control box 1. An inner push plate 15 is slidably connected to the first slide rail 14. In this embodiment, the inner push plate 15 is supported to slide by two first slide rails 14 on one side of the control box 1.

[0026] Please combine Figure 3 As shown, in this embodiment, the inner push plate 15 is provided with two push grooves 16, and the two push grooves 16 are set at an inclined balance. In other embodiments, other numbers of push grooves 16 can be set according to specific circumstances.

[0028] With the above technical solution, when the lever 23 moves along the push groove 16 to the uppermost end of the push groove 16, the support plate 7 is pushed upward;

[0029] Conversely, when the lever 23 moves along the push groove 16 to the lowest end of the push groove 16, the support plate 7 is pushed down;

[0030] Please combine Figure 4 As shown, in this embodiment, a second slide rail 21 is installed on the side of the support plate 7 away from the inner push plate 15.

[0032] Please combine Figure 3 As shown, the inner push plate drive mechanism includes a first lead screw 13 rotatably connected to one side of the control box 1. The first lead screw 13 is threadedly connected to one side of the inner push plate 15. A second handwheel 12 is fixedly connected to one end of the first lead screw 13. By rotating the second handwheel 12, the first lead screw 13 is driven to rotate, thereby pushing the inner push plate 15.

[0033] Please combine Figure 3 As shown, the support plate limiting mechanism includes slide rods 3 that are slidably connected to both sides of the support plate 7, and both ends of the two slide rods 3 are fixedly connected to one side of the control box 1.

[0034] When the support plate 7 is pushed up and down by the inner push plate 15, it can slide along the direction of the slide rod 3, and the slide rod 3 provides stability.

[0035] Please combine Figure 5As shown, the equal-spacing adjustment mechanism includes a slide groove 24 opened on the support plate 7. A synchronization plate 26 is slidably connected to the inner side of the slide groove 24. An outer push plate 6 is fixedly connected to the side of the synchronization plate 26 away from the inner push plate 15. A plurality of equidistant inclined grooves 18 are opened on the outer push plate 6. Eight equidistant inclined grooves 18 are paired with eight fixed rods 25, and each fixed rod 25 is slidably connected to the inner side of the corresponding equidistant inclined groove 18. A synchronization plate drive mechanism is provided on the other side of the synchronization plate 26 to make the synchronization plate 26 slide up and down along the slide groove 24.

[0036] Please combine Figure 4 As shown, the synchronous plate drive mechanism includes a second lead screw 17 rotatably connected to the side of the support plate 7 away from the outer push plate 6.

[0037] With the above technical solution, when the No. 1 handwheel 8 is rotated, the outer push plate 6 is pushed upward, and the distance between two adjacent dispensing nozzles 9 decreases; conversely, when the outer push plate 6 is moved downward, the distance between two adjacent dispensing nozzles 9 increases.

[0038] Please combine Figure 1 As shown, the delivery pump mechanism includes eight peristaltic pumps 2 installed on one side of the control box 1, each peristaltic pump 2 being configured to cooperate with a drainage hose 20;

[0039] Please combine Figure 2 As shown, an LED control panel 27 is installed on one side of the control box 1. The LED control panel 27 is electrically connected to eight peristaltic pumps 2. A drainage hose 20 is connected to the upper side of each dispensing nozzle 9. A bracket 19 is installed on the upper side of each mounting bracket 11. Each drainage hose 20 passes through the inner side of the bracket 19 and is configured to cooperate with the peristaltic pump 2.

[0040] Please combine Figure 1 As shown, a workbench 4 is fixedly connected to one side of the control box 1. A reagent kit feeding mechanism 5 is provided on the workbench 4. The reagent kit feeding mechanism 5 is a mature and well-known technology in the field of liquid dispensers and is not within the scope of protection of this utility model.

[0041] Example 2:

[0042] The previous embodiment used a manual adjustment method to set equal spacing or height. In the second embodiment, the second handwheel 12 and the first handwheel 8 can be replaced with servo motors. A laser rangefinder and other sensors are installed on the control box 1. Each servo motor is electrically connected to the LED control panel 27, which can realize fully automatic adjustment of height and spacing. It is suitable for large reagent kit packaging assembly line operations and is also within the protection scope of this utility model.

[0043] The implementation principle of an automatic dispensing device for reagent kit production in this application embodiment is as follows: When it is necessary to adjust the spacing between dispensing nozzles 9, turn the first handwheel 8 to drive the second lead screw 17 to rotate, push the synchronization plate 26 to slide up and down along the inner side of the slide groove 24, and push the outer push plate 6 to move up and down through the synchronization plate 26. Since the outer push plate 6 has multiple specially distributed equidistant inclined grooves 18, when each fixed rod 25 slides inside the equidistant inclined groove 18, under the limiting action of the second slide rail 21, multiple dispensing nozzles 9 together with the slider 22, the mounting support 11 and the positioning hoop 10 can move closer or further away from each other, and each dispensing nozzle 9 is still set at equal intervals after the movement.

[0044] When it is necessary to adjust the height between the dispensing nozzle 9 and the reagent kit, the No. 1 screw 13 is rotated by turning the No. 2 handwheel 12, which in turn drives the inner push plate 15 to move along the No. 1 slide rail 14. The push groove 16 on the inner push plate 15 can push the locking rod 23 on the back of the support plate 7, thereby pushing the support plate 7 up and down, thus achieving the function of adjusting the height of the dispensing nozzle 9.

[0045] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
