[0041] In the processing procedure of the base material, before the surface of the base material is coated and processed, the base material needs to be ultrasonically cleaned to clean the surface of the base material, so as to ensure the subsequent coating effect of the base material.For the cleaning of the sheet-shaped base material, a straight cylinder structure needs to be arranged, and the base material is inserted into the straight cylinder structure for ultrasonic cleaning.However, the contact area between the base material and the straight cylinder structure is too large, which causes residual marks to appear at the position where the base material contacts the straight cylinder structure, the cleaning effect of the surface of the base material is not good, and then the coating quality of the subsequent base material coating is unstable, and the base material is prone to demolding.

[0042] In order to solve the above problems, such as Figures 1-4As shown, the embodiment provides a substrate cleaning tool. The substrate cleaning tool comprises a fixing frame 300, a supporting structure 200 and a leaning structure 100, wherein the supporting structure 200 is fixed with the fixing frame 300, the supporting structure 200 has a supporting end face for supporting a substrate 2000, the supporting end face is covered with upper and lower through holes 230, the leaning structure 100 is fixed with the fixing frame 300 and is arranged above the supporting structure 200 in a spaced manner, the leaning structure 100 comprises a plurality of rigid wires 110, each of the rigid wires 110 extends along a first direction in an S shape, the plurality of rigid wires 110 are arranged in a second direction in sequence, the bending directions of the adjacent two rigid wires 110 are opposite, and the adjacent two rigid wires 110 form a plurality of leaning rings arranged in the first direction in a spaced manner, each of the leaning rings is used for supporting a substrate 2000, the contact between the leaning ring and the substrate 2000 is point contact, and the first direction and the second direction extend along the horizontal direction and are perpendicular to each other.

[0043] The substrate cleaning tool can reduce the contact area between the supporting end face and the substrate 2000 when the substrate 2000 is supported on the supporting end face by arranging the supporting structure 200 and the leaning structure 100 in a spaced manner from bottom to top at the fixing frame 300 and arranging the upper and lower through holes 230 on the supporting end face of the supporting structure 200, the plurality of rigid wires 110 extending along the first direction in an S shape are arranged in the second direction in sequence by arranging the plurality of rigid wires 110 in the leaning structure 100, the first direction and the second direction extend along the horizontal direction and are perpendicular to each other, the bending directions of the adjacent two rigid wires 110 are opposite, the adjacent two rigid wires 110 form a plurality of leaning rings arranged in the first direction in a spaced manner by using the feature that the bending directions are opposite, each of the leaning rings supports a substrate 2000, the substrate 2000 is provided with leaning support along the horizontal direction on the basis of the vertical support provided by the supporting structure 200, thereby realizing the accommodation and fixation of the substrate 2000, and since the rigid wires 110 extend along the first direction in an S shape, the contact between the substrate 2000 and the leaning ring is point contact when the substrate 2000 leans on the leaning ring, the contact area between the substrate 2000 and the substrate cleaning tool is greatly reduced, the cleaning effect of the substrate 2000 is ensured, and the subsequent coating effect of the substrate 2000 is ensured.

[0044] It should be noted that in the embodiment, the first direction is the front-rear direction, the second direction is the left-right direction, and 19 rigid wires 110 extending in the front-rear direction in an S shape are arranged in the leaning structure 100 in sequence along the left-right direction. Adjacent two rigid wires 110 jointly form 29 leaning rings arranged at intervals along the front-rear direction.

[0045] In addition, the substrate cleaning tool provided in the embodiment is not only suitable for sheet-shaped substrates, but also suitable for various substrates that have leaning requirements when being contained and fixed.

[0046] In an optional solution, the rigid wire 110 is formed by laser cutting of a metal plate.

By subjecting the surface of the rigid wire 110 to chemical polishing treatment, the surface smoothness of the rigid wire 110 can be greatly improved. When the substrate 2000 is subjected to subsequent ultrasonic cleaning, even if the substrate 2000 and the rigid wire 110 slide in abutment, the rigid wire 110 will not cause abrasion to the surface of the substrate 2000. The specific polishing steps and polishing principles of chemical polishing belong to the prior art, and will not be described here.

[0048] As an optional solution, as Figure 3As shown, the leaning structure 100 further comprises a first frame 120, wherein the first frame 120 is fixedly connected with the fixing frame 300, and the first frame 120 has a first accommodating cavity penetratingly arranged in the up-down direction, and the rigid wire 110 is arranged in the first accommodating cavity and fixedly connected with the cavity wall of the first accommodating cavity. By arranging the first frame 120 in the leaning structure 100, and fixing the first frame 120 with the fixing frame 300, and arranging the first accommodating cavity penetratingly in the first frame 120, and arranging the rigid wire 110 in the first accommodating cavity and fixedly connecting the rigid wire 110 with the cavity wall of the first accommodating cavity, the stable fixation of the rigid wire 110 with the fixing frame 300 is realized, and the overall structural strength of the substrate cleaning tool is improved. It should be noted that in the present embodiment, the first frame 120 is a rectangular frame, and the first accommodating cavity is a rectangular accommodating cavity, so as to realize the accommodation and fixation of the plurality of rigid wires 110 in the form of a rectangle. Moreover, the rigid wire 110 and the first frame 120 are fixed by welding, and the first frame 120 and the fixing frame 300 are fixed by welding. In other embodiments, the rigid wire 110 and the first frame 120, and the first frame 120 and the fixing frame 300 can also be fixed by bonding or riveting, and the present embodiment is not limited in particular.

[0049] In order to further improve the leaning effect on the substrate 2000, the substrate cleaning tool comprises at least two groups of leaning structures 100, and the at least two groups of leaning structures 100 are fixedly arranged on the fixing frame 300 in the up-down direction and are all located above the supporting structure 200. It should be noted that in the present embodiment, the substrate cleaning tool has two groups of leaning structures 100, and the two groups of leaning structures 100 are fixedly arranged on the fixing frame 300 in the up-down direction and are all located above the supporting structure 200. In other embodiments, three groups, four groups or more groups of leaning structures 100 can be arranged in the substrate cleaning tool according to the actual size of the substrate 2000, and the present embodiment is not limited in particular.

[0050] In combination with Figure 4The specific structure of the supporting structure 200 is described. The supporting structure 200 comprises a second frame 220 and a supporting net 210, wherein the second frame 220 is fixedly connected with the fixing frame 300, the second frame 220 has a second accommodating cavity penetrating in the up-down direction, the supporting net 210 has a supporting end surface, the supporting net 210 is arranged in the second accommodating cavity and fixedly connected with the cavity wall of the second accommodating cavity, and the supporting net 210 is covered with the avoiding through holes 230. By arranging the supporting structure 200 as the second frame 220 and the supporting net 210, arranging the second accommodating cavity penetrating in the up-down direction in the second frame 220, arranging the supporting net 210 in the second accommodating cavity and fixedly connecting the supporting net 210 with the cavity wall of the second accommodating cavity, and fixedly connecting the second frame 220 with the fixing frame 300, the stable fixation of the supporting net 210 with the fixing frame 300 is realized, and by covering the supporting net 210 with the avoiding through holes 230, the contact area of the supporting net 210 with the substrate 2000 can be greatly reduced when the supporting net 210 supports the substrate 2000. It should be noted that in the embodiment, the first frame 120 and the second frame 220 have the same size specification, and when the first frame 120 and the second frame 220 are fixed on the fixing frame 300 in sequence, the overall appearance of the substrate cleaning tool can be improved.

[0051] In addition, in the embodiment, the supporting net 210 and the second frame 220 are fixed together by welding, and the second frame 220 and the fixing frame 300 are fixed together by welding. In other embodiments, the supporting net 210 and the second frame 220 can be fixed by bonding, riveting or other methods, and the second frame 220 and the fixing frame 300 can be fixed by bonding, riveting or other methods, and the embodiment is not limited in particular.

[0052] After the substrate 2000 is cleaned by the substrate cleaning tool, the substrate 2000 and the substrate cleaning tool need to be taken out of the cleaning liquid. Since the supporting net 210 is located at the lowermost part of the substrate cleaning tool, the cleaning liquid is easy to accumulate on the supporting net 210. If the cleaning liquid accumulated on the supporting net 210 is not cleaned in time, the supporting net 210 is easy to rust, which shortens the service life of the substrate cleaning tool. In order to improve the protection of the supporting net 210 and prevent the supporting net 210 from rusting, in the embodiment, the surface of the supporting net 210 is plated with chromium, and the chromium layer on the outer surface of the supporting net 210 can isolate the supporting net 210 from the cleaning agent and the air, so as to achieve the effect of rust prevention. In other embodiments, the surface of the supporting net 210 can be plated with zinc, nickel or copper, and the embodiment is not limited in particular.

[0053] As an optional solution, as shown in FIG. 8, the supporting net 210 is provided with a plurality of through holes 230, and the through holes 230 are arranged in the form of a grid. Figure 5As shown, the fixing frame 300 comprises a plurality of fixing columns 310, wherein the plurality of fixing columns 310 are arranged at intervals around the periphery of the first frame 120 and the second frame 220, and the plurality of fixing columns 310 are fixedly connected with the first frame 120 and the second frame 220. By fixing the plurality of fixing columns 310 at intervals around the periphery of the first frame 120 and the second frame 220, the first frame 120 and the second frame 220 are firmly fixed.

[0054] To facilitate determination of the vertical distance between the supporting net 210 and the rigid wire 110, the outer peripheral wall of the fixing column 310 is provided with a scale extending in the up-down direction. It can be understood that, in actual operation, the base material 2000 is produced according to a set specification, and the specific specification of the base material 2000 is known. To improve the cleaning effect of the base material 2000, a plurality of sets of base material cleaning tooling can be produced, and the vertical distance between the supporting net 210 and the rigid wire 110 in the base material cleaning tooling of different specifications is different. When cleaning the base material 2000, the appropriate base material cleaning tooling is selected according to the actual specification of the base material 2000. When selecting the base material cleaning tooling, the vertical distance between the supporting net 210 and the rigid wire 110 can be quickly determined according to the scale on the fixing column 310, and then the correct base material cleaning tooling is quickly selected, and the work efficiency is improved.

[0055] In an optional solution, the fixing frame 300 further comprises a handle (not shown in the figure), which is fixedly connected with the fixing column 310 and located at the upper end of the fixing column 310. By fixing the handle at the upper end of the fixing column 310, when it is necessary to transfer the base material cleaning tooling to the cleaning equipment or remove the base material cleaning tooling from the cleaning equipment, the staff can be facilitated to grasp and operate, and the transfer efficiency of the base material cleaning tooling is improved.
