[0047] As shown in Figure 4 In this embodiment, the supporting plate 30 is provided with a long strip-shaped leg slot 31 and a positioning hole 33 which cooperates with the positioning column 25 on the handle 20. The long edge of the supporting plate 30 is provided with a groove 32 which avoids the position of the pipe shell.

[0048] As shown in Figure 5 In this embodiment, the partition 40 is composed of a plurality of matrix slots 41, and the height is 5mm.

[0049] As shown in Figure 6 This is a structure diagram of the cleaning basket 10 of the embodiment loaded with a circuit board 60 and a partition 40.

[0050] As shown in Figure 7As shown, the entire drain transfer basket 50 is constructed from stainless steel strips with a diameter of 5mm. A handle 54 is located at the center of the drain transfer basket 50. Cleaning basket grooves 51 are located on both sides of the handle 54. The depth of the cleaning basket grooves 51 is 2 / 3 of the height of the cleaning basket 10. A recessed retrieval groove 52 is located on the short side of the cleaning basket groove 51. A limiting groove 53, used in conjunction with the draining platform of the ultrasonic spray cleaning equipment, is located below the handle 54.

[0051] like Figure 8 As shown, in this embodiment, the tube shell 70 to be cleaned is placed on the tray 30 in the cleaning basket 10, and the cleaning basket 10 is placed in the cleaning basket groove 51 of the drain transfer basket 50. The limiting groove 53 passes through the positioning boss 55 of the drain table of the ultrasonic spray cleaning equipment to complete the positioning.

[0052] This invention discloses a universal circuit cleaning device applicable to both cases involving a circuit board 60 and a pre-assembled tube shell 70. It is simple to manufacture and easy to operate, effectively protecting the circuit while offering versatility, safety, convenience, efficiency, and long service life. The cleaning basket 10, used in conjunction with the drain transfer basket 50, enables stable and rapid draining of waste liquid, safe transfer, and simultaneous cleaning by both baskets 10. The tray 30, used in conjunction with the cleaning basket 10, allows thinner and softer guide legs to suspend without stress, separating the tube shell to prevent collisions and protecting its appearance. The partition 40, used in conjunction with the cleaning basket 10, separates the circuit board to prevent collisions and protect the circuit.

[0053] The cleaning basket 10 is made of 1mm thick 304 stainless steel perforated plate in multiple sizes. This material is sturdy, durable, not easily deformed, and has a long service life. The size of the cleaning basket 10 must be smaller than the size of the heating ultrasonic tank, and the height of the cleaning basket 10 should not exceed half the depth of the liquid tank of the heating cleaning machine.

[0054] The bottom surface 12 of the cleaning basket 10 is a stainless steel perforated plate with a hole diameter of 1mm. The perforations are distributed in a through-hole pattern, meaning that adjacent holes are staggered and the distance between adjacent holes is 3mm. In this design, the small-sized perforations on the bottom surface 12 ensure that the cleaning agent can be discharged smoothly, while the hole spacing, which is not a multiple of 2.54mm, ensures that the vertical leads of the circuit casing will not protrude from the perforations on the bottom surface and cause damage to the appearance.

[0055] The cleaning basket 10 has four perforated stainless steel plates 11 with 6mm diameter holes for drainage. The perforations on the side walls 11 are arranged in a through-hole pattern with a spacing of 10mm between adjacent holes. This design ensures rapid drainage of waste liquid while protecting the cleaning components from falling off the sides.

[0056] The bottom surface 12 of the cleaning basket 10 is provided with drainage holes 13. The bottom surface 12 is designed with 45° cuts at the four corners, with a dimension of 1cm in each direction. In this design, the drainage holes 13 can accelerate the outflow of waste liquid when the cleaning basket 10 is tilted at a small angle, and can also prevent circuits with a side length greater than 1cm from falling off the bottom surface during the drainage process.

[0057] The cleaning basket 10 is provided with two multifunctional handles 20 on the side, and the two handles 20 on the side of the cleaning basket 10 can effectively avoid scalding after heating and cleaning. The handle 20 is made of 304 stainless steel strip with a diameter of 3 mm. The rotating shaft 23 passes through the shaft tube 15 with a hole diameter of 4 mm welded and fixed on the side wall 11 to realize the connection with the cleaning basket 10. The bottom width of the rotating groove 24 is 6 mm, and the length from the bottom of the groove to the rotating shaft is equal to the length of the stainless steel tube from the top of the cleaning basket 10. The size can ensure that the handle rotates within a range of 180° along the rotating shaft. In the open state of the handle 20, the long handle 21 and the short handle 22 are both outside the cleaning basket 10, and the short handle 22 is close to the outside of the side wall 11, so as to ensure that the long handle 21 does not turn outward, and at this time, the long handle 21 serves as the handle of the cleaning basket 10. In the closed state of the handle 20, the long handle 21 is inside the cleaning basket 10, the long side of the "L" is close to the inside side wall 11 of the cleaning basket 10, the short side of the "L" is parallel to the bottom surface 12 of the cleaning basket 10, and the short handle 22 is vertically upward. The short side of the long handle 21 is provided with a positioning column 25, which is vertically upward in the closed state of the handle 20. The structure design cooperates with the supporting plate 30, the supporting plate 30 is placed on the short side of the "L" of the long handle 21, the positioning column 25 passes through the positioning hole 33 at the corresponding position of the supporting plate 30, at this time, the long handle 21 supports the supporting plate 30 to make the thin and soft legs suspended to avoid stress, and the short handle 22 serves as the handle of the cleaning basket 10.

[0058] The supporting plate 30 is made of PBT polyester material, which can be placed flat in the cleaning basket 10 and supported by the short side of the long handle 21. According to the size and spacing of the legs of the pipe shell 70 to be cleaned, a long strip-shaped leg groove 31 is arranged, and the positioning hole 33 for positioning the supporting plate 30 to avoid shaking and the groove 32 for facilitating the taking and placing of the supporting plate 30 are arranged. The design limits the position of the pipe shell 70 to be cleaned by reasonably arranging the long strip-shaped leg groove 31, cooperates with the handle 20 to make the supporting plate 30 not shake, the pipe shell not collide and the leg not bear stress during the cleaning process; the groove 32 is arranged to facilitate the taking and placing operation of the supporting plate.

[0059] The fence 40 is made of PBT polyester material, which can be placed flat in the cleaning basket 10 and close to the bottom surface 12. The matrix type groove 41 with a height of 5 mm is designed according to the size of the peripheral circuit board. The design of the matrix type groove 41 with a height of 5 mm can avoid the stacking and collision of the circuit board during the cleaning process.

[0060] The materials used by the supporting plate and the fence have the characteristics of preventing static electricity, corrosion resistance, stable nature and softness, which will not scratch the circuit.

[0061] The leaching transfer basket 50 is made of 304 stainless steel strip with a diameter of 5 mm, and is composed of a cleaning basket groove 51 and a handle 54. The leaching transfer basket 50 is provided with two cleaning basket grooves 51 located at two sides of the handle 54, and the size is larger than that of the cleaning basket 10, and the depth is 2 / 3 of the height of the cleaning basket 10. A concave taking groove 52 is designed at the short side to facilitate taking of the cleaning basket 10. The handle 54 is arranged in the middle of the leaching transfer basket 50 to ensure balance on both sides. A limiting groove 53 is arranged below the handle for use of the leaching table of the ultrasonic spraying cleaning equipment. The convex positioning column on the leaching table of the equipment is inserted into the limiting groove 53 to effectively prevent the leaching transfer basket 50 from sliding during the leaching process.

[0062] The following briefly describes the cleaning operation process: preparation before cleaning: when the to-be-cleaned parts are circuit boards 60, the handle 20 is rotated to the open state, the matched partition 40 is placed at the bottom of the cleaning basket 10, and the circuit boards 60 are placed one by one; when the to-be-cleaned parts are to-be-cleaned pipe shells 70 and the legs are thin and soft, the handle 20 is rotated to the closed state, the matched supporting plate 30 is placed on the short side of the long handle 21 "L", and the to-be-cleaned pipe shells 70 are placed one by one. Except the above two cases, if there is no special requirement, the to-be-cleaned parts can be directly placed in the cleaning basket 10.

[0063] Cleaning process: the cleaning basket 10 loaded with the to-be-cleaned parts is placed in the heated ultrasonic cleaning equipment, and the handle is higher than the cleaning agent liquid surface by more than 5 cm; after the cleaning program is executed, the cleaning basket 10 is lifted by holding the handles 20 at both sides of the cleaning basket 10, and after the cleaning liquid is quickly discharged from the bottom surface 12, the side surface 11, and the drainage hole 13, the cleaning basket 10 is stably carried by both hands to the cleaning basket groove of the leaching transfer basket 50; the leaching transfer basket 50 is placed on the leaching table of the ultrasonic spraying cleaning equipment, the limiting groove 53 is positioned through the positioning convex column of the leaching table to realize positioning, and the ultrasonic spraying equipment is started to execute the cleaning program. After the ultrasonic spraying cleaning is completed, the leaching transfer basket 50 is slightly lifted to be inclined at a small angle, the waste liquid is discharged, and the cleaning is completed.

[0064] As can be seen from the above technical solution, by designing the cleaning basket 10, the supporting plate 30, the partition 40, and the leaching transfer basket 50, the safe cleaning and transfer function of common types of circuit boards and pipe shells with completed circuit assembly are realized.
