[0048] The embodiments of the present application disclose a rotary cleaning device.

[0049] Please refer to Figure 2 , an embodiment of a rotary cleaning device provided in the embodiments of the present application includes:

[0050] A fixing component and a spraying component.

[0051] The fixing component is used to fix the substrate wafer 3.

[0052] The spraying component includes a first spraying member 11, a second spraying member 12, and a spraying driver 13;

[0053] A plurality of first spray holes 111 for spraying and cleaning the first surface of the substrate wafer 3 on the fixing component are provided on the first spraying member 11; a plurality of second spray holes (not shown in the figure) for spraying and cleaning the second surface of the substrate wafer 3 on the fixing component are provided on the second spraying member 12.

[0054] The spray drive 13 is connected to the first spray member 11 and / or the second spray member 12, and is used to drive the first spray member 11 and / or the second spray member 12 to rotate.

[0055] In the rotary cleaning device designed in the present application, the spray assembly is designed with a first spray member 11 capable of spray-cleaning the first surface of the substrate film 3 on the fixed assembly and a second spray member 12 capable of spray-cleaning the second surface of the substrate film 3, so as to realize simultaneous spray-cleaning of the two surfaces of the substrate film 3, greatly improving the cleaning effect. Moreover, the spray assembly is also designed with a spray drive 13, which can drive the first spray member 11 and / or the second spray member 12 to rotate to realize rotary spray cleaning, and has a better cleaning effect compared with the direct spray cleaning method.

[0056] The above-mentioned first spray member 11, second spray member 12, and fixed assembly can be prepared from PEEK material, and there is no specific limitation.

[0057] The above is the first embodiment of a rotary cleaning device provided by the present application. The following is the second embodiment of a rotary cleaning device provided by the present application. For details, please refer to Figures 1 to 3 。

[0058] Based on the solution of the above-mentioned first embodiment:

[0059] Further, as Figure 1 shown, it further includes a moving plate 5 and a plate drive 4.

[0060] The plate drive 4 is connected to the moving plate 5 and is used to drive the moving plate 5 to move along the first horizontal straight line direction. The fixed assembly is installed on the moving plate 5. By driving the moving plate 5 to reciprocate through the plate drive 4, the substrate film 3 on the fixed assembly can be driven to reciprocate, so as to realize reciprocating dynamic cleaning operation and further improve the cleaning effect.

[0061] Further, as Figure 1 shown, the fixed assembly includes two jigs 2. Compared with the single jig 2 design, it can realize the cleaning operation of two substrate films 3 at a time, further improving the cleaning efficiency.

[0062] The two jigs 2 are spaced apart along the second horizontal straight line direction perpendicular to the first horizontal straight line direction and are symmetrically arranged with respect to a preset plane perpendicular to the second horizontal straight line direction.

[0063] The jig 2 is used to fix the substrate wafer 3 in an inclined manner, and the first surface of the substrate wafer 3 close to the preset surface is inclined downward, while the second surface away from the preset surface is inclined upward; the first spraying member 11 is a pipe structure, vertically arranged above the moving plate 5, and its central axis coincides with the preset surface; the width of the gap space between the substrate wafers 3 arranged on the two symmetrically arranged jigs 2 should be greater than the width of the first spraying member 11 to ensure that the moving plate 5 will not be interfered by the first spraying member 11 when moving. The inclination angle of the substrate wafer 3 in this application can be 45° or other angles.

[0064] The outer peripheral wall of the first spraying member 11 is provided with first spray holes 111, and the first spray holes 111 are evenly distributed.

[0065] As Figure 2 shown, taking the number of jigs 2 as two as an example, the second spraying member 12 is correspondingly designed as two and is a disk structure; the second spraying member 12 can be arranged parallel to the substrate wafer 3 on the jig 2. Correspondingly, the surface of the second spraying member 12 facing the substrate wafer 3 is provided with second spray holes, and the second spray holes are evenly distributed.

[0066] Furthermore, as Figure 1 and Figure 2 shown, for better fixed installation, the spraying assembly further includes a spraying bracket 14, and the spraying bracket 14 is in an inverted U-shaped structure.

[0067] The first spraying member 11, the second spraying member 12 and the spraying driver 13 are installed on the spraying bracket 14.

[0068] A first pipe joint 15 is connected to the first spraying member 11, and a second pipe joint 16 is connected to the second spraying member 12. The first pipe joint 15 and the second pipe joint 16 are respectively used to connect the cleaning liquid supply source.

[0069] Furthermore, in order to ensure rotational drive and at the same time avoid affecting the supply of the cleaning liquid, the spraying driver 13 is a hollow shaft rotating motor.

[0070] This application is preferably designed such that the spraying driver 13 is connected to the second spraying member 12. If there are two second spraying members 12, then there are also two corresponding spraying drivers 13 to achieve one-to-one connection. Other quantities also have one-to-one cooperation, which is not limited.

[0071] The second pipe joint 16 can pass through the hollow shaft of the spraying driver 13 and is rotationally connected to the second spraying member 12. Specifically, it can be connected through a rotary connector to ensure conduction with the second spraying member 12 without affecting the rotation of the second spraying member 12.

[0072] Furthermore, as Figure 1As shown, the plate driver 4 can be designed as a lead screw slider. Taking this as an example, the slider of the plate driver 4 is connected to the moving plate 5. Of course, it can also be an electric push rod, a telescopic cylinder linear displacement mechanism, and there is no specific limitation.

[0073] Furthermore, the fixing components are designed to be at least two and are arranged at intervals; correspondingly, the spraying components are also designed to be at least two and are in one-to-one correspondence with the fixing components, realizing at least double-station cleaning operations and further improving the cleaning efficiency.

[0074] Furthermore, as Figure 3 shown, in order to be able to fix the substrate wafer 3, the fixture 2 is provided with a card slot 21 for the substrate wafer 3 to be inserted.

[0075] Furthermore, as Figure 3 shown, there are two card slots 21 on the fixture 2 and they are arranged at intervals; the design of the spaced double card slots 21 can play a better role in fixing the substrate wafer 3.

[0076] Furthermore, as Figure 3 shown, in terms of the structural design of the fixture 2, it includes a connecting part 22 and a supporting part 23.

[0077] The connecting part 22 is fixed on the moving plate 5, and there are two supporting parts 23 which are arranged at intervals on the connecting part 22; taking the design of two card slots 21 as an example, then each supporting part 23 is respectively provided with a card slot 21.

[0078] Among them, the connecting part 22 can be a U-shaped plate structure, which saves manufacturing materials while meeting certain strength requirements.

[0079] The supporting part 23 can be a convex block structure, which is integrally formed with the connecting part 22, reducing the assembly process and making production more convenient.

[0080] Working principle (taking two fixing components and four fixtures 2 as an example):

[0081] 1. Manually install four substrate wafers 3 into the four fixtures 2 on the moving plate 5;

[0082] 2. The plate driver 4 drives the moving plate 5 to reciprocate, and then drives the fixture 2 and the substrate wafer 3 to reciprocate;

[0083] 3. Connect the first pipe joint 15 and the second pipe joint 16, and control the spraying driver 13 to drive the second spraying part 12 to rotate to realize the simultaneous cleaning of the two surfaces of the substrate wafer 3.

[0084] The above has introduced in detail a rotary cleaning device provided by the present application. For those of ordinary skill in the art, according to the idea of the embodiments of the present application, there will be changes in the specific implementation manners and application scopes. In summary, the content of this specification should not be construed as a limitation to the present application.
