[0014] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts should fall within the scope of protection of the present invention.

[0015] In an embodiment of the present invention, Figure 1 This is a structural entity diagram provided based on the specific structure of an adjustable cleaning carrier for circuit cleaning of the utility model, such as Figure 1 As shown, the utility model specifically includes

[0016] A base 1, a limit strip 2 and a limit block 3, the base 1 is provided with a hollow window 11, one set of opposite sides of the hollow window 11 is provided with a sliding groove 12, the sliding groove 12 is arranged along the width direction of the base 1, the limit strip 2 is arranged in the hollow window 11, the two ends of the limit strip 2 are slidably arranged in the sliding groove 12, the limit block 3 is arranged along the length direction of the base 1 and is arranged on another set of opposite sides of the hollow window 11.

[0017] The base is made of heat-resistant and corrosion-resistant alloy material, the surface is treated with anti-oxidation, and the limiting component is made of PEEK organic plastic.

[0018] Among them, Figure 2As shown, the limiting strip 2 includes a base plate 21, a threaded hole 22, and a limiting protrusion 23. The threaded hole 22 and the limiting protrusion 23 are provided on the base plate 21, with the threaded hole 22 located on both sides of the limiting protrusion 23. The limiting protrusion 23 is positioned within the hollow window 11, and the threaded hole 22 is positioned within the sliding groove 12. The threaded hole 22 is threadedly connected to the adjusting nut 4. To prevent the limiting strip from falling off, the diameter of the adjusting nut 4 is larger than the width of the sliding groove 12.

[0019] The limiting block 3 includes a plurality of limiting nuts arranged along the length direction of the base 1, and the limiting nuts 1 are threadedly connected to the base. Figure 4 As shown, the cross section of the limiting nut is in an inverted trapezoidal shape.

[0020] The process of using this utility model is as follows:

[0021] When turning the adjustment nut 4, be careful to control the force. Do not use too much force to cause the nut to slip, resulting in component damage and circuit fixation failure.

[0022] The material requirements for the structure are as follows:

[0023] like Figure 3 As shown, by loosening the adjusting nut 4, the limit bar 2 is controlled to move up and down on the base 1, and the circuit is limited to the step formed by the limit protrusion of the limit bar 2 and the bottom plate. The edge limit nut is in a fixed state and the height can be adjusted according to the thickness of the circuit, thereby fixing the circuit.

[0024] According to the different sizes of circuits, place them on the steps of the limit bar 2 and the platform of the limit nut 4, tighten the adjusting nut 4, fix the circuit, put it into the cleaning material box, load it into the cleaning equipment, and wait for cleaning.

[0025] After cleaning is completed, loosen the adjusting nut 4 to easily remove the circuit on the step, put it into the tray and proceed to the next step. Repeat the above operation to achieve continuous operation.

[0026] It should be noted that when rotating the adjustment nut 4, you must control the force and avoid excessive force to cause the nut to slip, resulting in component damage and circuit fixation failure.

[0027] The base 1 and the adjusting nut 4 are made of corrosion-resistant alloy material and are treated with anti-oxidation to avoid oxidation and corrosion by high-temperature alkaline cleaning fluid during the cleaning process; the limit strip 2 is made of organic PEEK material to prevent scratches on the placed circuit during the cleaning process.

[0028] The base 1 is deburred and has a smooth surface to prevent the adjusting nut 4 from getting stuck during use and affecting the upward and downward movement of the limit bar 2.

[0029] Finally, it should be noted that the above specific implementation methods are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to examples, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
