Description

Technical Field

[0001] This utility model relates to the field of wafer processing technology, and in particular to a semi-automatic liquid addition trolley for adding liquid. Background Technology

[0002] In the chip manufacturing process, a chip etching and cleaning process is required. The chip etching and cleaning machine contains two parts: an acid tank and a water tank. The acid tank contains a strong acid or strong alkaline solution.

[0003] The solution in the corrosion tank needs to be changed regularly. During the solution change, the solution in the acid tank must first be drained, and then the solution from the container must be poured into the acid tank. Currently, the solution change method still involves the operator manually lifting the container above the machine and pouring it out. This method of adding solution poses many safety hazards, as there is a high risk of solution splashing onto the operator's skin. Therefore, a semi-automatic solution-adding cart is designed to assist in adding solution, thereby avoiding direct contact between the operator and the solution and reducing the risk. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a semi-automatic liquid addition trolley with a simple structure and convenient operation. When adding liquid, there is no need for manual lifting and placing of the solution tank containing corrosive solution, which reduces the risk of injury to operators during the solution addition process. The operator can easily replace the solution tank at the bottom of the trolley to cooperate with the liquid replacement operation, which greatly simplifies the operation process and makes it safer for operators to operate.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: a semi-automatic liquid filling cart for adding liquid is provided, including a cart body, a water tank placement chamber and a blower pump storage chamber. The water tank placement chamber is provided in the lower part of the cart body, and the blower pump storage chamber is provided in the upper part of the cart body. A water tank is installed in the water tank placement chamber, and a blower pump is installed in the blower pump storage chamber. The blower pump and the water tank are connected by a water pipe. A panel structure is provided at the upper end of the cart body, and the air pipe of the blower pump passes through the panel structure. Universal wheels are installed at the four corners of the lower end face of the cart body.

[0006] In this technical solution, a water tank placement chamber and an airbag pump storage chamber are set on the trolley body to facilitate the installation of the water tank and airbag pump. The installation of the airbag pump facilitates liquid addition, avoids manual liquid addition by staff, and reduces operational risks. At the same time, the universal wheel structure facilitates the movement of the trolley body.

[0007] As a supplement to this technical solution, handle structures are installed at both ends of the upper surface of the panel structure. In this technical solution, the handle structures facilitate the pushing of the trolley body.

[0008] As a supplement to this technical solution, a central support panel is provided at the bottom of the airbag pump housing chamber, and the water pipe of the airbag pump passes through the central support panel and is connected to the water storage tank.

[0009] In this technical solution, a central support panel is provided to facilitate the connection between the airbag pump and the water storage tank.

[0010] As a supplement to this technical solution, a lower support panel is provided at the bottom of the water storage tank placement chamber, and a water storage tank mounting platform is provided on the middle of the upper surface of the lower support panel. A leak-proof groove matching the water storage tank is provided on the water storage tank mounting platform.

[0011] A water storage tank mounting platform is used to limit the water storage tank, and a leak-proof tank is used to prevent liquid leakage.

[0012] As a supplement to this technical solution, a lower support frame is horizontally installed at the center of the lower end face of the lower support panel.

[0013] As a supplement to this technical solution, the front end of the water storage tank placement chamber is provided with an opening, and a door panel structure is installed in the opening. One side of the door panel structure is connected to the trolley body through several hinge structures, and a door panel handle is installed on the other side of the door panel structure.

[0014] Beneficial effects: This utility model relates to a semi-automatic liquid dispensing cart for adding liquid. By setting a water tank placement chamber and a wind pump storage chamber on the cart body, the water tank and wind pump can be easily installed. The installation of the wind pump facilitates liquid dispensing, avoiding manual liquid dispensing by operators and reducing operational risks. At the same time, the universal wheel structure facilitates the movement of the cart body. It has the characteristics of simple structure, convenient operation, simplified operation process, convenient automatic liquid dispensing, and reduced operational risks. Attached Figure Description
