DETAILED DESCRIPTION

[0036] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0037] like Figure 1 and Figure 2 As shown, at least one embodiment provides a cleaning tank, comprising: a main cleaning tank 1 having a accommodating cavity, wherein the main cleaning tank 1 is provided with at least two supporting modules along a first direction X; the supporting modules include at least three accommodating positions, which are rectangular; the accommodating positions are arranged in sequence along a second direction Y of the main cleaning tank 1, and the length direction of the accommodating positions is parallel to the second direction Y of the main cleaning tank; and a cleaning sub-tank 2, which is arranged around the main cleaning tank 1.

[0038] In some embodiments, a main cleaning tank 1 is provided to hold cleaning liquid, and a sub-cleaning tank 2 is provided around the main cleaning tank 1 to hold cleaning liquid overflowing from the main cleaning tank 1, and the main cleaning tank 1 and the sub-cleaning tank 2 are connected by a liquid medicine pipe 30, so that the cleaning liquid overflowing from the main cleaning tank 1 can enter the sub-cleaning tank 2, and the liquid in the sub-cleaning tank 2 is circulated to the main cleaning tank 1 through the liquid medicine pipe 30, thereby realizing the circulation and mixing of the liquid in the cleaning tank.

[0039] In some embodiments, by setting the main cleaning tank 1 to be rectangular and providing at least two carrying modules, each carrying module is configured to include at least three accommodating positions, each accommodating position is provided with at least one flower basket, so that the main cleaning tank 1 can clean at least 6 flower baskets at the same time, thereby improving the cleaning efficiency.

[0040] In some embodiments, the side wall of the main cleaning tank 1 may also be arc-shaped.

[0041] In some embodiments, an overflow screen plate 3 is provided between the main cleaning tank 1 and the auxiliary cleaning tank 2. Specifically, the overflow screen plate 3 includes but is not limited to being provided on the outer wall of the upper end of the main cleaning tank 1 in a clamping manner, and does not exceed the top of the main cleaning tank 1, so that the cleaning liquid overflowing from the main cleaning tank 1 passes through the overflow screen plate 3 and enters the auxiliary cleaning tank 2, and the uniformity of the cleaning liquid entering the auxiliary cleaning tank 2 is improved by the provided overflow screen plate 3.

[0042] In some embodiments, the height of the wall of the main cleaning tank 1 is smaller than the height of the wall of the auxiliary cleaning tank 2; and an overflow port 10 is opened at the upper end of the wall of the main cleaning tank 1 to allow the cleaning liquid in the tank to overflow.

[0043] Specific as Figure 3 As shown, in some embodiments, a flow equalizing mesh plate 4 is provided at the bottom of the main cleaning tank 1; the cleaning liquid in the sub-cleaning tank 2 enters into the main cleaning tank 1 through the liquid pipeline 30 and the liquid inlet hole opened at the bottom of the main cleaning tank 1, and the liquid is evenly mixed through the flow equalizing holes evenly distributed on the flow equalizing mesh plate 4 and then flows into the main cleaning tank 1, thereby improving the uniformity of the liquid and further improving the cleaning effect.

[0044] In some embodiments, an emergency tank 6 is further provided in the main cleaning tank 1; the top of the emergency tank 6 extends out from the top of the main cleaning tank 1, and the top of the emergency tank 6 is lower than the top of the sub-cleaning tank 2. When the drainage pipeline of the cleaning tank is blocked, the main cleaning tank 1 will continue to be replenished with liquid, but it cannot be discharged. If it is not discovered in time, the excessive cleaning liquid will overflow from the sub-cleaning tank 2, thereby causing the risk of corrosion. At this time, the emergency tank 6 is provided to play a role. Specifically, if the cleaning liquid in the cleaning tank is continuously replenished, it will overflow into the emergency tank 6 after overflowing from the main cleaning tank 1. At this time, the emergency water outlet 61 at the bottom of the emergency tank 6 discharges the cleaning liquid through the pipeline, thereby preventing the cleaning liquid from overflowing from the sub-cleaning tank 2 and causing environmental pollution.

[0045] In some embodiments, a bubbling tube 5 is further provided in the main cleaning tank 1. The bubbling tube 5 is located above the flow equalizing mesh plate 4, and a plurality of air holes are opened on the tube wall. The bubbling tube 5 supplies gas to the main cleaning tank 1 through an external gas source, and the gas is blown into the main cleaning tank 1 through the air holes, thereby further improving the uniformity of the liquid in the main cleaning tank 1. In addition, the presence of gas enables the cleaning liquid to always maintain a flow circulation, and can clean every part of the silicon wafer, thereby improving the cleaning effect.

[0046] As a preferred embodiment, the main cleaning tank 1 is further connected to a liquid replenishing tube, so as to continuously replenish the cleaning liquid into the main cleaning tank 1, so that the cleaning liquid in the main cleaning tank 1 always maintains an overflow state.

[0047] As an optional embodiment, a replenishing pipe is provided at the bottom of the main cleaning tank 1. The cleaning liquid passes through the replenishing pipe and flows through the flow equalizing mesh plate 4 and then enters the main tank. With the continuous replenishment of the cleaning liquid, the cleaning liquid in the main cleaning tank 1 will overflow from the top of the main cleaning tank 1. The overflowed cleaning liquid flows evenly through the overflow mesh plate 3 and then flows into the sub-cleaning tank 2. The sub-cleaning tank 2 and the main cleaning tank 1 are connected by a liquid pipe 30, so that the liquid in the sub-cleaning tank 2 is returned to the main cleaning tank 1, thereby realizing the circulation of the cleaning liquid.

[0048] As an optional embodiment, a tank cover (not shown in the figure) is further provided at the top opening of the main cleaning tank 1 to prevent the solution in the main cleaning tank 1 from volatilizing.

[0049] On the other hand, the utility model also provides a cleaning device, including: the above-mentioned cleaning tank and the blowing device 7 and the suction pipe 8; the blowing device 7 and the suction pipe 8 are both arranged above the cleaning tank to achieve air circulation in the cleaning tank through the blowing device 7 and the suction pipe 8.

[0050] In some embodiments, since the structure of the cleaning tank is rectangular, considering the length of the long side of the cleaning tank, in order to further improve the ventilation effect in the cleaning tank, a blowing device 7 and a suction pipe 8 are provided above the cleaning tank to ensure the ventilation effect, and the exhaust pipe and the suction pipe 8 are usually arranged on the cleaning tank that can produce harmful gases. In addition, a manipulator for grabbing the flower basket in the tank can also be provided above the cleaning tank. Thus, the flower basket is hung by the manipulator and transferred and cleaned in each liquid medicine. When the manipulator places the flower basket in the cleaning tank, the liquid medicine in the tank always keeps bubbling and overflowing, which can improve its cleaning effect. After cleaning, the manipulator sends it to the next liquid medicine tank or the next process.

[0051] In summary, the cleaning tank and cleaning equipment of the present invention contain cleaning liquid through the main cleaning tank 1, contain the cleaning liquid overflowing from the main cleaning tank 1 through the sub-cleaning tank 2 arranged around the main cleaning tank 1, and connect the main cleaning tank 1 and the sub-cleaning tank 2 through the liquid pipe 30, so that the cleaning liquid overflowing from the main cleaning tank 1 can enter the sub-cleaning tank 2, and the liquid in the sub-cleaning tank 2 is circulated to the main cleaning tank 1 through the liquid pipe 30, thereby realizing the circulation and mixing of the liquid in the cleaning tank.
