DETAILED DESCRIPTION

[0051] In order to make the above object, features and advantages of the present application more obvious, a preferred embodiment is described in detail below, and the accompanying drawings are used for detailed description. Obviously, the described embodiments are some embodiments of the present application, but not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0052] It should be noted that similar reference numerals and letters represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings. In addition, in the drawings, the thickness of components may be exaggerated or reduced in order to effectively describe the technical content.

[0053] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0054] See also Figure 1 and Figure 2 At least one embodiment provides an ultrasonic cleaning device, comprising: a cleaning tank body 100, and an ultrasonic vibration component and a conveying component 400 located in the cleaning tank body 100; wherein the conveying component 400 is arranged in the vibration area of ​​the ultrasonic vibration component; the feeding end and the discharging end of the conveying component 400 are respectively connected to the sheet inlet 110 and the sheet outlet 120 of the cleaning tank body 100; the sheet inlet 110 and the sheet outlet 120 are provided with a flexible sealing gasket 130; the flexible sealing gasket 130 is provided with a slit 131 suitable for the substrate to be cleaned to pass through. By arranging flexible sealing gaskets 130 at the film inlet 110 and the film outlet 120 of the cleaning tank body 100, when the glass substrate passes through the slit 131 of the flexible sealing gasket 130, the glass substrate is sealed by the slit 131, thereby preventing the cleaning liquid from overflowing from the film inlet 110 and the film outlet 120, ensuring the stability of the cleaning liquid level, and thus ensuring the cleaning effect of the glass substrate. Since the glass substrate continuously enters the cleaning tank body 100, the flexible sealing gaskets 130 of the film inlet 110 and the film outlet 120 will continue to seal with the glass substrate, thereby reducing the overflow of the cleaning liquid from the slit 131 of the flexible sealing gasket 130.

[0055] In a preferred embodiment, the ultrasonic cleaning device is a flow-through upper and lower ultrasonic cleaning device, and the ultrasonic vibration assembly includes an upper ultrasonic vibration plate 200 and a lower ultrasonic vibration plate 300. The upper ultrasonic vibration plate 200 and the lower ultrasonic vibration plate 300 are used to clean the glass substrate without dead angles, thereby improving cleaning efficiency.

[0056] The flexible sealing pad 130 provided at the sheet inlet 110 and / or the sheet outlet 120 of the ultrasonic cleaning device constitutes an anti-overflow structure, which is applicable not only to the ultrasonic cleaning device but also to other cleaning devices.

[0057] See also Figure 3 Specifically, in order to adapt to the sealing requirements of glass substrates of different thicknesses, in a preferred embodiment, the slit 131 is in the shape of a "door".

[0058] See also Figure 2 In some embodiments, the flexible sealing gasket 130 is fixed to the outer wall of the cleaning tank body 100 via a sealing flange 140. A feed port 141 is defined in the sealing flange 140 at a position corresponding to the slit 131. The sealing flange 140 secures the flexible sealing gasket 130 to prevent it from moving. Furthermore, a feed port 141 is defined in the position corresponding to the slit 131 to facilitate the feeding of glass substrates.

[0059] Please continue reading Figure 1 as well as Figure 2 In some embodiments, the conveyor assembly 400 includes multiple lower conveyor shafts 410 spaced apart and at least two upper conveyor shafts 420 . The two upper conveyor shafts 420 are disposed above the lower conveyor shafts 410 at both ends of the conveyor assembly 400 . To prevent the glass substrate from warping at the film inlet 110 and the film outlet 120 , the upper conveyor shafts 420 are disposed at the corresponding locations to press down on the glass substrate and prevent it from warping.

[0060] In some embodiments, a mounting groove 150 is provided at a position corresponding to the cleaning tank body 100 and the lower conveying shaft 410; an axial end sealing gasket 160 and an axial end flange 170 are provided at the mounting groove 150; the axial end sealing gasket 160 is provided on the inner wall of the mounting groove 150 of the cleaning tank body 100 through the axial end flange 170; the lower conveying shaft 410 and the upper conveying shaft 420 are installed on the cleaning tank body 100 after passing through the corresponding axial end sealing gaskets 160.

[0061] See also Figure 2 and Figure 4 Specifically, the shaft-end sealing gasket 160 includes an upper sealing sheet 161 and a lower sealing sheet 162. The gap between the upper and lower sealing sheets 161, 162 is shaped like a Chinese character "J." The upper and lower conveying shafts 420 and 410 pass through the corresponding upper and lower sealing sheets 161, 162, respectively, with the distance of the gaps matching the conveying intervals between the lower and upper conveying shafts 410 and 420. By adjusting the gap between the upper and lower sealing sheets 161, 162, the conveying requirements for glass substrates of varying thicknesses can be met.

[0062] In order to facilitate adjustment of the gap between the upper sealing sheet 161 and the lower sealing sheet 162, in a preferred embodiment, both the upper sealing sheet 161 and the lower sealing sheet 162 are provided with waist-shaped fixing holes 163. The waist-shaped fixing holes 163 are used to adjust and fix the gap between the upper sealing sheet 161 and the lower sealing sheet 162.

[0063] Since the shaft end sealing gasket 160 and the shaft end flange 170 adopt hard sealing, there are gaps, and the upper sealing piece 161 and the lower sealing piece 162 also leave a few gaps, so the cleaning liquid will inevitably flow out from the gaps. In order to avoid the overflow liquid from entering the driving part of the upper conveying shaft 420 and the lower conveying shaft 410, in some embodiments, a water baffle 430 is arranged on the shaft body of the lower conveying shaft 410 and the upper conveying shaft 420 extending out of the cleaning tank body 100. The water baffle 430 can block the cleaning liquid flowing out along the shaft from the cleaning tank body, and since the upper conveying shaft 420 and the lower conveying shaft 410 are rotating, the cleaning liquid will be thrown out along the side wall of the upper conveying shaft 420 or the lower conveying shaft 410, avoiding the cleaning liquid from entering the driving part of the upper conveying shaft 420 and the lower conveying shaft 410.

[0064] Please refer to Figure 2 In the preferred embodiments, in order to avoid waste of cleaning liquid, a liquid supplement tank 500 is arranged below the cleaning tank body 100. The overflow cleaning liquid from the cleaning tank body 100 flows into the liquid supplement tank 500, and the overflow cleaning liquid is received by the liquid supplement tank 500, thereby facilitating subsequent recycling.

[0065] Please refer to Figure 2 and Figure 5 In some embodiments, the side wall of the cleaning tank body 100 is provided with a liquid inlet 180 and a liquid outlet 190. The cleaning tank body 100 is provided with a flow equalizing pipe 191 communicating with the liquid inlet 180. The flow equalizing pipe 191 is provided with a plurality of flow equalizing openings 1911. The cleaning liquid supplemented from the liquid inlet 180 is uniformly flowed into the cleaning tank body 100 through the flow equalizing openings 1911, and the fluctuation of the surface of the cleaning liquid is reduced, thereby improving the effect of ultrasonic cleaning.

[0066] Specifically, the liquid inlet 180 of the cleaning tank body 100 is connected with the liquid supplement tank 500. Since the overflow cleaning liquid from the cleaning tank body flows into the liquid supplement tank 500, the recycling of the cleaning liquid is realized, thereby avoiding waste of the cleaning liquid.

[0067] In order to detect whether the liquid level of the cleaning liquid in the cleaning tank body reaches the working liquid level, in the preferred embodiments, the cleaning tank body is further provided with a liquid level float ball 1912. When the liquid level float ball 1912 floats to the working liquid level, it indicates that the cleaning liquid reaches the working liquid level.

[0068] Please continue to refer to Figure 2 In some embodiments, the cleaning tank body 100 is further provided with a temperature detection sensor 1913. The temperature detection sensor 1913 is used to detect the temperature of the cleaning liquid in real time.

[0069] In summary, the utility model provides a kind of ultrasonic cleaning device, comprising: cleaning tank main body 100, upper ultrasonic vibration plate 200, lower ultrasonic vibration plate 300 and conveying assembly 400;The sheet inlet 110 and the sheet outlet 120 are provided with flexible sealing gasket 130;The flexible sealing gasket 130 is opened with the slit 131 suitable for the substrate to be cleaned to pass through.Glass substrate passes through the slit 131 of flexible sealing gasket 130, and the glass substrate is sealed by slit 131, to avoid overflow of cleaning fluid from sheet inlet 110 and sheet outlet 120, ensure the stability of cleaning liquid level, to ensure the cleaning effect of glass substrate, since glass substrate is continuously entered into cleaning tank main body 100, the flexible sealing gasket 130 of sheet inlet 110 and sheet outlet 120 will continue to seal with glass substrate, to reduce the overflow amount of cleaning fluid from the slit 131 of flexible sealing gasket 130.
