Description

Technical Field

[0001] The utility model relates to the technical field of circuit board cleaning, in particular to a pneumatic liquid transfer pump device for a circuit board cleaning agent. Background Art

[0002] Circuit boards (circuit boards) need to be cleaned during the processing process. Since circuit boards usually contain electronic components, they are not suitable for direct cleaning with water. Special cleaning agents are required to achieve better cleaning and deoxidation effects. When using cleaning agents, pump equipment is required to achieve efficient, accurate and safe delivery of circuit board cleaning agents.

[0003] At present, pneumatic diaphragm pumps are often used to transport circuit board cleaning agents. However, after installation, existing pneumatic diaphragm pumps are not easy to move and are difficult to transfer between multiple cleaning areas. They lack flexibility in use, and the connection between the pneumatic diaphragm pump and the delivery pipeline is prone to dripping. The cleaning agent falls directly on the ground and contaminates the ground, making it difficult to clean up later.

[0004] To this end, we propose a pneumatic pipetting pump device for circuit board cleaning agent to solve the above problems. Utility Model Content

[0008] In a further embodiment, a rubber pad is provided between the base and the fixing frame of the pneumatic diaphragm pump, and the base and the fixing frame of the pneumatic diaphragm pump are in close contact with the rubber pad.

[0009] In a further embodiment, the inner diameters of the tube holes are different.

[0010] In a further embodiment, a screw is provided at the bottom end of the U-shaped frame, which passes through the interior of the connecting plate, and the connecting plate is fixed to the side of the chassis. The screw passes through the bottom end of the connecting plate and is screwed with a nut through the external thread.

[0011] In a further embodiment, the casters are symmetrically distributed at the four bottom corners of the chassis.

[0012] In a further embodiment, the caster is a universal wheel with a brake.

[0013] In a further embodiment, the drain port of the chassis is located at the lowest point of the chassis, and the inner bottom surface of the chassis is inclined toward the drain port.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] The utility model is provided with a pneumatic diaphragm pump, and after installation, its working position can be adjusted by moving the chassis, which has higher flexibility in use and is convenient for later maintenance or replacement. At the same time, the chassis can collect dripping cleaning agent and collect the cleaning agent in a unified manner, which is convenient for later centralized treatment and saves the trouble of cleaning the ground in the later stage. The combing plate is provided with pipe holes of different specifications, which can store and organize the inlet pipes of the pneumatic diaphragm pump. BRIEF DESCRIPTION OF THE DRAWINGS
