Abstract
Description
Technical Field
[0001] The utility model relates to a full-automatic liquid dripping mechanism. Background Art
[0002] Most of the fully automatic immunohistochemical staining machines on the market are three-axis devices. When multiple mixed liquids need to be dripped at the same location, most of them use the injection needle on this three-axis device to suck the liquid and then move it from one location to another to drip the liquid. This requires a high power motor because it needs to drip liquid in a short time. If the number is too large, it will greatly waste the running time and reduce the efficiency. Summary of the invention

[0017] The utility model is further described below in conjunction with the accompanying drawings.
[0018] like Figure 1 and Figure 2 The utility model is a fully automatic dripping mechanism, comprising a horizontal motion actuator 1, an injection needle 2 and a vertical motion actuator 3. The vertical motion actuator 3 is installed at the linear moving free end of the horizontal motion actuator 1, the injection needle 2 is arranged at the moving free end of the vertical motion actuator 3, and the vertical motion actuator 3 drives the injection needle 2 to move vertically.
[0019] The horizontal motion actuator 1 in the utility model adopts an electric screw, which has stable transmission and high transmission accuracy, and the vertical motion actuator 3 is installed on the slider of the electric screw.
[0020] like Figure 3 The vertical motion actuator 3 includes a mounting seat 31, a sliding block 32, a linkage arm 33 and a motor 34. The mounting seat 31 is mounted on the slider of the electric lead screw. A vertically arranged slide groove is provided on the mounting seat 31. The sliding block 32 is slidably connected in the slide groove. The motor 34 is fixed on the mounting seat 31. Two linkage arms 33 are hinged to each other, one of which is hinged to the sliding block 32, and the other linkage arm 33 is fixedly connected to the rotating shaft of the motor 34. A mounting arm 35 for mounting the injection needle 2 is fixed on the sliding block 32.
[0021] Combination Figure 4, the motor 34 can be set to an operating range of 0°-90°. When the motor 34 is running at the 0° position, the sliding block 32 connected to the injection needle 2 is at the bottom position. When the motor 34 is running at the 90° position, the sliding block 32 is at the top position. In this case, it is only necessary to obtain the operating signal of the motor 34 to know the current position of the injection needle 2. Therefore, the photoelectric detection of the upper and lower positions of the injection needle 2 can be omitted. At the same time, the entire operation of the motor 34 linkage is stable (crank connecting rod), the torque is large, the mechanism is cheap and easy to manufacture, and the motor screw and other components can be omitted, so the cost of the entire structure is low.
[0022] In order to make the appearance beautiful and realize dustproof of the sliding block 32, a protective cover 36 is provided on the outer side of the mounting seat 31, and the sliding block 32, the linkage arm 33 and the motor 34 are all placed in the protective cover. A drag chain is connected to the outer wall of the protective cover 36, and there are control wires, infusion tubes, etc. in the drag chain. The infusion tube is connected to the top of the injection needle 2, and the control wires are connected to the motor 34.
[0023] like Figure 5 Before the mechanism is operated, the injection needle 2 is at one end of the motor near the electric lead screw. The sliding block 32 connected to the injection needle 2 is at the lowest position. When dripping is required, the motor 34 first drives the injection needle 2 to the highest position. Then the horizontal motion actuator 1 operates to move the injection needle 2 to the position where dripping is required. When the slider stops, the motor 34 drives the injection needle 2 to move downward. When the injection needle 2 stops, dripping is performed. After dripping, the motor 34 drives the injection needle 2 to the highest position. When the injection needle 2 stops, the horizontal motion actuator 1 drives the injection needle 2 to move to the next position where dripping is required.
[0024] When there are multiple dyeing racks on the equipment on which the entire mechanism is installed and liquid dripping needs to be performed at multiple positions at the same time, the mechanism of the utility model can be installed next to different dyeing racks to achieve a highly efficient liquid dripping process without mutual interference.
[0025] The above is only a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements without departing from the principle of the present invention, and these improvements should also be regarded as within the protection scope of the present invention.
