[0041] The present invention will be described more clearly and completely below by way of embodiments in conjunction with the accompanying drawings, but the present invention is not limited to the scope of the embodiments.
[0042] like Figures 1 to 7 As shown, this embodiment includes an acid cleaning device 100. The acid cleaning device 100 can be used for etching a glass substrate.
[0043] Combine Figure 1The pickling device 100 includes: a shell 11, a mesh plate 12 and a cover 13. The shell 11 has a receiving cavity 111 for placing a glass substrate; the mesh plate 12 is arranged in the receiving cavity 111; the glass substrate is arranged on the side of the mesh plate 12; and the cover 13 is covered on the shell 11 to close the receiving cavity 111. By inserting the mesh plate 12 into the receiving cavity 111 of the shell 11 and placing the glass substrate in the receiving cavity 111 at the same time, the volume of the receiving cavity 111 can be occupied, the volume of the acid solution contained in the receiving cavity 111 can be reduced, the amount of pickling solution can be reduced, and the waste of pickling solution can be avoided. At the same time, the concentration of the pickling solution can be exchanged through the through holes in the mesh plate 12, which can ensure the uniformity of the solution concentration during the corrosion process.
[0044] The pickling device 100 also includes an inner liner 14, which is disposed within the accommodating chamber 111 and has a slot 141, into which the screen 12 is secured. The inner liner 14 further occupies space within the accommodating chamber 111, further reducing the volume of the acidic solution contained within the accommodating chamber 111, thereby reducing the amount of pickling solution used and avoiding waste. The slot 141 of the inner liner 14 also secures the screen 12, improving the stability of the screen 12 and the stability of the glass substrate.
[0045] The outer circumference of the inner container 14 is in contact with the inner circumference of the accommodating cavity 111 . The inner container 14 has a hollow area 142 . The mesh plate 12 and the glass substrate are both disposed in the hollow area 142 .
[0046] The cross section of the hollow area 142 is rectangular as a whole, and the slot 141 is provided on the short side of the hollow area 142. The width of the slot 141 is smaller than that of the hollow area 142, so as to facilitate the taking and placing of the screen 12 and the glass substrate.
[0047] There are two screen plates 12, and both screen plates 12 are inserted into corresponding slots 141, and the two screen plates 12 are spaced apart, and the glass substrate is inserted between the two screen plates 12. The glass substrate is inserted between the two screen plates 12 so that both sides of the glass substrate can be corroded synchronously and evenly, which can improve the etching speed and quality of the glass substrate. The hydrofluoric acid etching of the glass substrate can also be carried out in an acid-resistant container similar to a beaker shape. Although this approach can save solution, it often fails to achieve the desired effect due to the different acid concentrations above and below the glass substrate. The pickling device 100 of this example can avoid the problem of uneven corrosion.
[0048] The inner container 14 is flush with the upper side of the accommodating cavity 111. Figure 3 Specifically, the inner liner 14 may include four stacked components as shown in the figure.
[0049] Optionally, the pickling device 100 further includes a fixing member 15, which is pressed onto the inner liner 14 and the housing 11 and is used to fix the inner liner 14 relative to the housing 11. The fixing member 15 can fix the inner liner 14 relative to the housing 11, thereby improving stability.
[0050] The cover 13 is provided on the top of the fixing member 15. The cover 13 is provided on the top of the fixing member 15 for better sealing.
[0051] Combine Figure 5 , the mesh plate 12 does not leak out of the accommodating cavity 111. There may also be a gap between the lower side of the mesh plate 12 and the bottom of the housing 11 to facilitate the flow of the solution.
[0052] The pickling device 100 is made of Teflon, which can prevent the pickling device 100 from being corroded.
[0053] The shell 11 can adopt an integrated structure to prevent leakage of acid solution and ensure the safety of the pickling device 100 during use.
[0054] The inner liner 14 can reduce the volume of the accommodating chamber 111, saving the acid solution needed for small-batch experiments in a laboratory environment, and has two slots 141, which can be inserted into two mesh plates 12, further reducing the container of the accommodating chamber 111. At the same time, the circular hole can also allow the concentration of the solution in the middle to exchange with the solutions on both sides.
[0055] The fixing member 15 can compact the inner tank and finally seal it with the cover 13 to prevent the acid liquid from gasifying and overflowing. The connection between the cover 13, the fixing member 15 and the housing 11 can also be sealed with a sealing strip to further improve the sealing performance of the pickling device 100.
[0056] In one embodiment, the pickling apparatus 100 is generally rectangular in shape. The pickling apparatus 100 may be no longer than 80 cm, no wider than 40 cm, and less than 50 cm in height. The housing 11 is a rectangular outer shell. The inner liner 14 has a shape similar to that of the housing 11. The mesh plate 12 may be a rectangular plate with through holes. The fixing member 15 is a hollow rectangular plate. The cover 13 is a rectangular plate.
[0057] The containers typically used for etching glass substrates have large capacities, leading to problems such as wasted solution. The pickling apparatus 100 of this example includes a housing 11, an inner container 14, two screens 12, a fixture 15, and a cover 13. The inner container 14 is mounted within the housing and secured by the fixture 15. The screen 12 is placed within the slot 141 of the inner container 14, which reduces the volume of the container and allows the concentration of the solution in the middle to be exchanged with that of the solutions on both sides through the circular holes, ensuring uniform solution concentration during the etching process. The cover 13 can be screwed to the fixture 15 to prevent harm to the human body from evaporating solution, thus ensuring the safety of the structure.
[0058] Although specific embodiments of the present invention have been described above, those skilled in the art will appreciate that these are merely illustrative and that the scope of protection of the present invention is defined by the appended claims. Those skilled in the art may make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, and such changes and modifications are intended to fall within the scope of protection of the present invention.
