Description

Technical Field

[0001] This utility model relates to the field of circuit board cleaning technology, specifically a motor controller circuit board cleaning device. Background Technology

[0002] Circuit boards, also known as printed circuit boards, come in many types. They miniaturize and visualize circuits, playing a crucial role in the mass production of fixed circuits and optimizing the layout of electrical appliances. Circuit boards are also called printed circuit boards (PCBs). Flexible printed circuit boards (FPCs), also known as flexible circuit boards, are made with polyimide or polyester film as the substrate. They are highly reliable and extremely flexible, characterized by high wiring density, light weight, thinness, and good bending properties. During manufacturing, dust and other impurities easily adhere to their surface, requiring specialized cleaning equipment for better later use.

[0003] The existing circuit board cleaning auxiliary equipment with application number 202122175730.3 includes a main body, in which a first rotating shaft, a second rotating shaft, and a third rotating shaft arranged horizontally are rotatably connected. The first and second rotating shafts are on the same axis, and the third rotating shaft is located below the first and second rotating shafts. The box contains cleaning fluid, and a spray rack is installed in the main body above the circuit board. The spray rack is connected to the box via a pipe, and multiple nozzles are evenly distributed and fixed on the lower end face of the spray rack. However, it requires a long loading and unloading time, resulting in poor cleaning continuity and low cleaning efficiency for motor controller circuit boards. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4In this embodiment of the utility model, a motor controller circuit board cleaning device includes a lower frame 1 and a liquid storage tank 11. A first upright plate 2 is provided on one side of the upper end of the lower frame 1. An upper support 3 is slidably provided on one upper end of the lower frame 1 via a guide rod 10 and a lead screw. A second upright plate 4 is provided on the upper side of the upper support 3. A conveyor wheel 6 is rotatably provided on one side of the first upright plate 2 and the second upright plate 4 via a connecting shaft 5. A conveyor belt 8 is wound around the two conveyor wheels 6. A conveyor groove 9 for laterally clamping the circuit board is provided between the two sets of conveyor belts 8. A second motor 27 is connected to one end of the connecting shaft 5 via a belt flywheel group 7. The second motor 27 is fixedly installed on the lower side of the lower end of the first upright plate 2 for laterally clamping, positioning and conveying the circuit board. Multiple circuit boards are sequentially conveyed to the rinsing station and the air drying station for rinsing and drying. Moreover, the cleaning is highly continuous and the loading and unloading are convenient and quick, thereby improving the efficiency of cleaning motor controller circuit boards.

[0024] like Figure 1 and Figure 4 As shown, in order to store liquid, a first liquid storage tank 24 and a second liquid storage tank 23 are provided inside the liquid storage tank 11 through a partition 26. The side walls of the first liquid storage tank 24 and the second liquid storage tank 23 inside the liquid storage tank 11 are provided with a drain port 25 and a drain valve. The first liquid storage tank 24 is also provided with a liquid inlet on one side. The first liquid storage tank 24 is used to store clean water, and the second liquid storage tank 23 is used to store waste liquid after cleaning to prevent liquid from splashing.

[0025] like Figure 1 and Figure 3 As shown, in order to clean the circuit board from top to bottom simultaneously, a rinsing nozzle 16 is provided on one side of the first liquid storage tank 24 via a water supply pipe 15 and a water pump 17.

The rinsing nozzle 16 and the air drying nozzle 21 are symmetrically arranged in two sets on the top and bottom of the horizontally conveyed circuit board. A dust filter box and an electric heating wire heating box 19 are also provided at one end of the air supply pipe 18. An air concentrator 22 is also provided on the outside of the air drying nozzle 21, which enables the horizontally conveyed circuit board to be cleaned from top to bottom simultaneously, which is beneficial to further improve the efficiency of circuit board cleaning.

[0026] like Figure 1 and Figure 2 As shown, in order to meet the horizontal clamping and conveying of circuit boards of different specifications, a lead screw including a lead screw 13 rotatably set on the upper part of the lower frame 1 is also provided. The upper bracket 3 is threadedly connected to the lead screw 13. One end of the lead screw 13 is connected to the first motor 14. Two conveyor belts 8 are arranged horizontally in parallel, and the longitudinal section of the conveyor belt 8 is an L-shaped section. This allows the second vertical plate 4 to be moved laterally by the lead screw, thereby adjusting the distance between the first vertical plate 2 and the second vertical plate 4, and thus adjusting the width of the conveying groove 9. This can meet the horizontal clamping and conveying processing of circuit boards of different specifications.

[0027] like Figure 2 and Figure 3 As shown, the width of the liquid storage tank 11 is greater than the width of the lower frame 1, and the liquid storage tank 11 is provided with casters 12 on the lower side, which makes it easy to move and adjust the liquid storage tank 11, thereby making it easy to adjust the position of the rinsing nozzle 16 and the air drying nozzle 21.

[0028] The working principle and usage process of this utility model are as follows: When in use, the circuit boards to be cleaned are horizontally clamped into the conveyor grooves 9 between the conveyor belts 8. Then, the second motor 27 and the belt flywheel group 7 drive the conveyor belt 8 to rotate horizontally, which is used to clamp and position the circuit boards horizontally and convey them. Multiple circuit boards are then conveyed to the rinsing station and the air drying station in sequence for rinsing and drying. Moreover, the cleaning is continuous and the loading and unloading are convenient and quick, thereby improving the efficiency of cleaning the motor controller circuit boards.
