[0024] like Figure 1 As shown:

[0025] A dilution head module has an unloading assembly, which includes a tank body 1 provided with a slide slot 2. Both ends of the slide slot 2 are respectively provided with a front baffle plate 6 and a rear baffle plate 7 installed on the tank body 1.

[0026] A sliding block 3 is provided in the chute 2 and is slidably connected thereto. The top opening 4 of the chute 2 is tapered, and a cavity for placing a dilution head 9 is provided on the sliding block 3 .

[0027] A spring 5 is installed in the slide groove 2 to drive the slider 3 to slide and reset along the slide groove 2 from the narrow mouth to the wide mouth side. The two ends of the spring 5 are respectively connected to the rear baffle 7 and the slider 3. The front baffle 6 is used to limit the slider 3 to prevent the slider 3 from excessive movement.

[0028] A drainage hole 8 communicating with the cavity is provided at the bottom of the tank body 1 . The drainage hole 8 is connected to a waste liquid recovery tank via a pipeline to realize automatic collection of liquid dripping from the dilution head 9 .

[0029] A dilution head module further comprises a dilution head 9, which is inserted into the cavity of the slider 3, connected to the dilution pump through a pipeline, and plug-connected to the liquid taking gun 14 arranged on the robot arm.

[0030] A liquid inlet head 12 connected to the inside of the dilution head 9 is installed on the outer peripheral surface of the dilution head 9, and the liquid inlet head 12 is connected to the dilution pump through a hose.

[0031] A connecting groove 10 is provided at the top of the dilution head 9, and an O-ring 11 is installed on the inner circumference of the connecting groove 10. The dilution head 9 is pluggably connected to the liquid extraction gun 14 of the robot arm through the connecting groove 10. The connection with the liquid extraction gun 14 on the robot arm is reinforced by the O-ring 11 to prevent the dilution head 9 from falling off during the plug-in process.

[0032] The outer peripheral surface of the dilution head 9 is provided with an annular groove 13 which is slidably engaged with the top opening 4 of the slide groove 2. When the slider 3 slides along the slide groove 2 from the wide mouth to the narrow mouth, the annular groove 13 is embedded in both sides of the top opening 4. The top opening 4 limits the dilution head 9, making it convenient for the robot arm liquid gun 14 to disengage from the connecting groove 10.

[0033] When installing the dilution head 10, the robot arm first moves to above the dilution head 9, and then moves downward, and the liquid taking gun 14 on the robot arm is plugged into the connecting groove 10 of the dilution head 9 to achieve the connection between the dilution head 9 and the robot arm.

[0034] When disassembling the dilution head 9, the dilution head 9 is first placed in the cavity of the slider 3 by the robotic arm, and then the robotic arm drives the slider 3 to slide along the slide groove 2 from the wide opening to the narrow opening. At this time, the annular groove 13 is embedded in both sides of the top opening 4, and then the robotic arm moves vertically upward, and the dilution head 9 and the liquid taking gun 14 of the robotic arm can be disassembled;

[0035] When the dilution head 9 and the liquid taking gun 14 of the robot arm are separated, the spring 5 drives the slider 3 to slide along the slide groove 2 from the narrow opening to the wide opening side to realize the reset of the slider 3, so as to facilitate the robot arm to take the dilution head next time.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
