[0016] Compared with the prior art, the technical solution of this utility model has the following advantages:

[0017] The workpiece cleaning device of this utility model, by adding the pump circulation assembly, enables the cleaning medium to be recycled. Combined with the added filter, impurities in the cleaning medium can be effectively filtered out for continued cleaning of the next batch of workpieces, thereby effectively saving cleaning medium consumption and reducing the cleaning cost.

[0036] As described in the background section, existing technologies for cleaning workpieces still have many problems. These will be explained in detail below.

[0037] Before coating workpieces (such as PCBA boards), it is necessary to clean and remove substances such as flux, oil film, and iron slag from their surfaces. However, current liquid storage tanks on the market are simply water tanks, which cannot meet the functions of circulating and filtering cleaning media or simultaneously loading and unloading multiple workpieces.

[0038] Based on this, the present invention provides a workpiece cleaning device. By adding the pump circulation assembly, the cleaning medium can be circulated for reuse. Combined with the added filter, impurities in the cleaning medium can be effectively filtered out for continued cleaning of the next batch of workpieces, thereby effectively saving cleaning medium consumption and reducing the cleaning cost of the workpieces. The addition of the carrying assembly facilitates the placement of multiple workpieces and allows for simultaneous loading and unloading of multiple workpieces, improving cleaning efficiency.

[0039] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0041] Please refer to Figure 1 and Figure 6 A workpiece cleaning device includes: a liquid storage tank 100, the liquid storage tank 100 including a cleaning area 100a and a filtration area 100b; a filter body (not shown), the filter body being assembled in the filtration area 100b; a pump circulation assembly (not shown), the pump circulation assembly being connected to the cleaning area 100a and the filtration area 100b respectively, for circulating the cleaning medium between the cleaning area 100a and the filtration area 100b; and a support assembly 200, the support assembly 200 being placed in the cleaning area 100a, the support assembly 200 being used to support and fix a plurality of workpieces.

[0042] By adding the pump circulation assembly, the cleaning medium can be recycled. Combined with the added filter, impurities in the cleaning medium can be effectively filtered out for reuse in the next batch of workpieces, thus effectively saving cleaning medium consumption and reducing cleaning costs. Adding the carrying assembly 200 facilitates the placement of multiple workpieces and allows for simultaneous loading and unloading, improving cleaning efficiency.

[0043] In this embodiment, the workpiece is a product to be coated, specifically a motor stator loaded with a PCBA board, wherein both the PCBA board and the motor stator need to be cleaned before coating.

[0044] PCBA boards are formed by mounting components onto a bare PCB (Printed Circuit Board) using SMT (Surface Mount Technology) or DIP (Dual In-line Package) insertion. PCBA boards are among the most common and crucial components in all electronic products. Similar to the neural network of the human brain, they are the core of all electronic products, almost determining their core structure, performance, and reliability.

[0045] In other embodiments, the workpiece may also be other components that are mounted on a PCBA board.

[0046] In other embodiments, the workpiece may also be a PCBA board.

[0047] In this embodiment, alcohol is used as the cleaning medium.

[0048] Please refer to Figure 2 and Figure 3 In this embodiment, the workpiece cleaning device further includes a draining tank 103, which is fixed to the filtration area 100b. The filter body is assembled in the draining tank 103, and the bottom of the draining tank 103 is hollow. Adding the draining tank 103 facilitates the placement and positioning of the filter body.

[0049] In this embodiment, the filter element can be filter cotton, lint-free cloth, or mesh. The filter element is laid flat at the bottom of the drain tank 103.

[0050] Please continue to refer to this. Figure 2 In this embodiment, there is a gap between the bottom of the draining tank 103 and the bottom of the filter area 100b, meaning that the draining tank 103 is fixed to the upper part of the filter area 100b. This allows the cleaning medium filtered by the filter body to flow out quickly from the bottom of the draining tank 103.

[0051] Please continue to refer to this. Figure 2 In this embodiment, the bottom of the drain tank 103 is an inclined surface S. The bottom of the inclined surface S can increase the filtration area, and the impurities filtered from the cleaning medium can first remain in the upper part of the inclined surface S, without blocking the flow of the cleaning medium to the lower part of the inclined surface S.

[0052] Please continue to refer to this. Figure 2In this embodiment, the drain tank 103 exposes the filter element, i.e., the top of the drain tank 103 is open. The open design of the drain tank 103 facilitates the replacement of the filter element.

[0053] Please refer to Figure 4 In this embodiment, the workpiece cleaning device further includes a baffle plate 104, which is disposed between the cleaning area 100a and the filtering area 100b, and has a water outlet 104a at its bottom. Since the motor stator in the workpiece is connected to wires, the addition of the baffle plate 104 prevents the cleaning medium flowing into the filtering area 100b from splashing onto the cleaning area 100a, thereby wetting the parts of the workpiece that do not require cleaning (e.g., the motor stator wires) placed in the cleaning area 100a, and thus damaging the workpiece.

[0054] Please continue to refer to this. Figure 2 and Figure 4 In this embodiment, the workpiece cleaning device further includes a slot 105, which is fixed between the cleaning area 100a and the filtering area 100b, and the baffle plate 104 is inserted into the slot 105. The slot 105 enables quick insertion and installation of the baffle plate 104.

[0055] Please refer to Figure 5 In this embodiment, the pump circulation assembly includes: an inlet pipe, one end of which is connected to the circulation inlet 106 of the filtration area 100b, and the inlet of the inlet pipe is located above the filter body; a pump body, the other end of which is connected to the pump body; and an outlet pipe, one end of which is connected to the pump body, and the other end of which is connected to the circulation outlet 107 of the cleaning area 100a.

[0056] Please continue to refer to this. Figure 5 In this embodiment, the bottom of the liquid storage tank 100 is inverted conical in shape to better collect the cleaning medium. The circulation outlet 107 is located at the bottom of the liquid storage tank 100, which facilitates better pumping by the pump body.

[0057] Please continue to refer to this. Figure 6In this embodiment, the supporting component 200 includes: a support plate 2001, on which a plurality of contoured openings 2002 are formed, the workpiece is assembled into the contoured openings 2002, and the contoured openings 2002 expose the cleaning surface of the workpiece; and a handle 2003, which is detachably connected to the support plate 2001. By designing the handle 2003 and the support plate 2001 to be detachably connected, only one handle 2003 is needed to connect to the support plate 2001 required for different workpieces, which greatly enhances versatility and effectively reduces costs.

[0058] Please refer to Figure 7 , Figure 8 and Figure 9 In this embodiment, the support plate 2001 has a plurality of gourd-shaped holes 2004; the handle 2003 has a plurality of support columns 2005, and the ends of the support columns 2005 have locking heads 2006 adapted to the gourd-shaped holes 2004; the locking heads 2006 of the handle 2003 pass through the large holes corresponding to the gourd-shaped holes 2004, and by rotating (e.g., clockwise) the handle 2003, the locking heads 2006 are limited to the small holes corresponding to the gourd-shaped holes 2004. When disassembly is required, it is only necessary to rotate the handle 2003 in the opposite direction (counterclockwise) to rotate the locking heads 2006 to the large holes corresponding to the gourd-shaped holes 2004.

[0059] Please continue to refer to this. Figure 6 and Figure 7 In this embodiment, the workpiece cleaning device further includes a wire management assembly 300, which is fixed to the supporting assembly 200. The wire management assembly 300 is used to wind and organize the wires of the workpiece (motor stator). Adding the wire management assembly 300 facilitates the organization and fixing of the workpiece wires. Specifically, the wire management assembly 300 includes several winding posts 3001 and wire pressing plates 3002. The motor stator wires are organized by winding them around the winding posts 3001, while the wire pressing plates 3002 limit the wires to prevent them from breaking.

[0060] Please continue to refer to this. Figure 6 and Figure 7 In this embodiment, the cable management assembly 300 is located between the handle 2003 and the support plate 2001. Specifically, the cable management assembly 300 is fixed within the space supported by the support column 2005 of the handle 2003.

[0061] Please continue to refer to this. Figure 6 and Figure 7In this embodiment, the support plate 2001 is provided with a drag-reducing opening 2007. Specifically, the drag-reducing opening 2007 is opened at a position corresponding to the cable management assembly 300. The workpiece will not be placed at this position. By adding the drag-reducing opening 2007, the resistance when placing the bearing assembly 200 into the cleaning medium and taking it out of the cleaning medium can be effectively reduced.

[0062] Please continue to refer to this. Figure 1 and in conjunction with references Figure 10 In this embodiment, the workpiece cleaning device further includes a shelf 400, which is placed in the cleaning area 100a, and the supporting component 200 is placed on the shelf 400. The shelf 400 supports the workpiece at a certain height, facilitating a more comprehensive and thorough cleaning of the workpiece surface by the cleaning medium.

[0063] It should be noted that in this embodiment, after the workpiece is positioned in the contour opening 2002, the cleaning surface of the PCBA board faces the bottom of the liquid storage tank 100. Therefore, by adding the shelf 400, a certain gap is created between the cleaning surface of the PCBA board and the bottom of the liquid storage tank 100, so that the cleaning medium can better clean the cleaning surface of the PCBA board. In addition, since the bottom of the liquid storage tank 100 is inverted conical, it cannot provide a flat surface for supporting the support component 200. Therefore, the shelf 400 also provides a flat support surface for the support component 200.

[0064] Please continue to refer to this. Figure 1 In this embodiment, the workpiece cleaning device further includes a cleaning cover 500, which covers the liquid storage tank 100. By equipping the liquid storage tank 100 with the cleaning cover 500, the cleaning cover 500 can be placed on the liquid storage tank 100 during cleaning to prevent the cleaning medium from splashing.

[0065] Please continue to refer to this. Figure 1 In this embodiment, the workpiece cleaning device further includes a frame 600, and the liquid storage tank 100 is fixed on the frame 600. Adding the frame 600 provides more stable support for the liquid storage tank 100.

[0066] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
