Description

Technical Field

[0001] This utility model generally relates to the field of ultra-thin glass, and more particularly to surface treatment equipment for ultra-thin glass. Background Technology

[0002] With the development of flexible screens and other devices, ultra-thin glass has emerged. This mainly refers to glass with a thickness of no more than 0.1 mm. Due to its combination of the advantages of both plastics and glass, it is a new material with significant application value. The processing of ultra-thin glass requires strengthening to enhance its performance. After strengthening, the surface of the ultra-thin glass will have minor imperfections. Therefore, micro-etching of the strengthened ultra-thin glass with acid is used to achieve better appearance and performance.

[0003] After surface treatment, ultra-thin glass needs to be cleaned as soon as possible to remove the acid residue on the surface. However, because ultra-thin glass is thin, it needs to be moved slowly and steadily when it is taken out of the acid solution and moved into the cleaning tank. During this process, the areas where acid accumulates on the bottom of the ultra-thin glass are very prone to leaving undesirable marks, which in turn affects the quality of the entire ultra-thin glass product. Utility Model Content

[0004] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide a surface treatment device for ultra-thin glass.

[0005] In a first aspect, a surface treatment apparatus for ultrathin glass is provided, comprising:

[0006] The first and second tanks are arranged in sequence. The first tank is used to hold the surface treatment liquid, and the second tank is used to hold the cleaning liquid.

[0007] A drive mechanism is used to move the ultra-thin glass within the surface treatment equipment;

[0008] A spray assembly is installed above the first tank and is used to spray and clean the ultra-thin glass.

[0009] As one possible implementation, the spray assembly includes at least two sets of spray nozzles arranged opposite each other, the spray nozzles being arranged along the length or width direction of the first groove.

[0010] As an implementation method, the spraying area of ​​the spraying assembly is located directly above the first trough, and the distance between the spraying assembly and the first trough is 10-20 cm.

[0011] In one possible implementation, the driving mechanism includes a first driving member and a second driving member, wherein the first driving member is used to drive the ultra-thin glass to move along the direction of entering or leaving the first groove, and the second driving member is used to drive the ultra-thin glass to move along the arrangement direction of the first groove and the second groove.

[0012] As an alternative implementation, a sealing cap is also included, which is mounted on the opening of the first groove and can be opened and closed at the opening of the first groove, for sealing the first groove when the ultrathin glass leaves the first groove.

[0013] As an option, the spray nozzle is a mist spray nozzle.

[0014] As an implementation method, the top surface of the sealing cover is an inclined surface that is higher in the middle and lower on the sides.

[0015] As an alternative implementation, a water tank is also included, which is connected to the spray assembly and supplies water to the spray assembly.

[0016] According to the technical solution provided in the embodiments of this application, the ultra-thin glass is sprayed by a spray assembly installed above the first tank, which reduces the concentration of acid accumulated on the ultra-thin glass and even performs preliminary cleaning, so that no bad marks are produced on the bottom of the ultra-thin glass where acid accumulates, thereby affecting the quality of the product.

[0024] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant utility model and not intended to limit the scope of the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.

[0025] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0026] Please refer to Figure 1 This embodiment provides a surface treatment device for ultra-thin glass, comprising:

[0027] The first tank 10 and the second tank 20 are arranged in sequence. The first tank 10 is used to hold the surface treatment liquid, and the second tank 20 is used to hold the cleaning liquid.

[0028] Drive mechanism 60, which is used to move the ultra-thin glass within the surface treatment equipment;

[0029] A spray assembly 40 is installed above the first tank 10 and is used to spray and clean the ultra-thin glass.

[0030] In this embodiment, a first tank 10 containing a surface treatment liquid is used to treat the surface of ultra-thin glass. Especially after the strengthening or polishing steps, the surface treatment liquid performs micro-etching on the surface of the ultra-thin glass, giving it good quality. After the ultra-thin glass is removed from the first tank 10, acid will accumulate at the bottom of the glass. The spray assembly 40 installed above the first tank 10 sprays the ultra-thin glass to reduce the concentration of the acid accumulated on the ultra-thin glass, and even perform preliminary cleaning, so that no bad marks will be formed at the bottom of the ultra-thin glass where the acid has accumulated, thus affecting the quality of the product.

[0031] refer to Figure 1As shown, the surface treatment equipment provided in this embodiment can generally be applied in the step after the ultra-thin glass is strengthened. After the ultra-thin glass is strengthened to 50%, it is placed in the surface treatment equipment. The surface treatment liquid is generally an acid, such as hydrofluoric acid, phosphoric acid, or sulfuric acid. The surface treatment liquid performs micro-etching on the surface of the ultra-thin glass. This treatment step is short, taking only a few seconds, and removes small imperfections on the surface of the ultra-thin glass, resulting in ultra-thin glass with good performance and appearance. Subsequently, the ultra-thin glass is moved to a pure water tank for immersion and cleaning. During the process of moving the ultra-thin glass from the surface treatment tank to the pure water tank, it is necessary to ensure the stability of the ultra-thin glass to prevent breakage or other problems during the movement. Therefore, the process of moving the glass from the surface treatment tank to the pure water tank generally takes 10-20 seconds. During the movement, the acid in the surface treatment tank accumulates at the bottom of the ultra-thin glass. The location where the acid accumulates is very likely to produce undesirable marks, affecting product quality. Therefore, the equipment has at least two tanks: the first tank 10 is a surface treatment tank, and the second tank 20 and subsequent third tanks are cleaning tanks. The cleaning solution is generally pure water. Multiple pieces of ultra-thin glass 50 are placed in containers such as cassettes (not all cassette structures are shown in the figure). Driven by the drive mechanism 60, they move sequentially from the first tank 10 to the next, realizing the surface treatment and cleaning of the ultra-thin glass 50. The ultra-thin glass enters the first tank 10 under the drive mechanism 60, stays briefly in the first tank 10 for surface treatment, and then leaves the first tank 10 under the drive mechanism 60. When the ultra-thin glass leaves the first tank 10, it is sprayed by a spray assembly 40 located above the first tank 10. The spray assembly 40 sprays pure water onto the ultra-thin glass to dilute and initially clean the acid on the ultra-thin glass, reducing the possibility of undesirable marks appearing on the ultra-thin glass.

[0032] The spray assembly 40 for pure water spraying is located above the first tank 10. When the ultra-thin glass leaves the first tank 10, the spray assembly 40 is turned on to spray pure water. This can dilute and clean the acid solution immediately or within a short time after the ultra-thin glass leaves the acid solution, thus preventing the formation of undesirable marks on the bottom of the ultra-thin glass.

[0033] Optionally, the spray assembly 40 includes at least two sets of spray nozzles 41 arranged opposite each other, the spray nozzles 41 being arranged along the length or width direction of the first groove 10.

[0034] like Figure 2 As shown, in this embodiment, two sets of spray nozzles 41 are provided above the first tank 10, preferably using... Figure 1 and Figure 2The spray pipes shown are arranged along the width or length of the first groove 10. The spray pipes are relatively long, and multiple spray nozzles 41 can be evenly opened on them for spraying. In this embodiment, the ultra-thin glass is generally placed in a cassette during surface treatment. The ultra-thin glass is vertically inserted into the cassette and arranged sequentially according to the space on the cassette, forming a... Figure 2 The arrangement shown has the spray nozzles 41 aligned with the ultra-thin glass, ensuring that the water sprayed from the spray pipes can cover each piece of glass, thus diluting the acid on each piece and ensuring that all glass is sprayed by the spray pipes, preventing undesirable marks from appearing on the glass surface.

[0035] In addition, the spray nozzles 41 on the spray pipe are adjusted to be positioned between adjacent ultra-thin glass, so that each spray nozzle 41 sprays onto the ultra-thin glass on both sides, ensuring the effectiveness and high efficiency of the spray pipe.

[0036] Optionally, the spraying area of ​​the spraying assembly 40 is located directly above the first groove 10, and the distance between the spraying assembly 40 and the first groove 10 is 10-20 cm.

[0037] In this embodiment, the spraying area is positioned directly above the first tank 10, and the spray pipes can be positioned on the side of the first tank 10, forming a configuration as shown below. Figure 1 The positional structure shown avoids the opening of the first groove 10, thus not affecting the vertical movement path of the cartridge assembly. Furthermore, the vertical distance between the spray pipe and the first groove 10 is small, allowing spraying to begin as soon as the cartridge carrying the ultra-thin glass leaves the first groove 10. This quickly reduces the concentration of acid on the glass, achieving the effect of preventing the aforementioned defects from appearing.

[0038] Optionally, the driving mechanism 60 includes a first driving member and a second driving member (not shown in the figure). The first driving member is used to drive the ultra-thin glass to move along the direction of entering or leaving the first groove 10, and the second driving member is used to drive the ultra-thin glass to move along the arrangement direction of the first groove 10 and the second groove 20.

[0039] In this embodiment, the ultra-thin glass is placed in a cartridge. The movement of the cartridge moves the ultra-thin glass from the tempering equipment to the first slot 10 and the subsequent second slot 20 in this embodiment. Preferably, the drive mechanism 60 is equipped with a hook, and the cartridge is hung on the hook and moved under the drive of the drive mechanism 60. A first drive member is provided to move the cartridge vertically, and a second drive member is provided to move the cartridge horizontally, so that it can enter the first slot 10 from the outside and be taken out from the first slot 10 for pure water spraying, and then enter the second slot 20, the third slot, etc. for soaking and cleaning.

[0040] Furthermore, it also includes a sealing cap 30, which is installed on the opening of the first groove 10 and can be opened and closed at the opening of the first groove 10, for sealing the first groove 10 when the ultra-thin glass leaves the first groove 10.

[0041] In this embodiment, to quickly spray the ultra-thin glass, the corresponding spraying area is positioned above the first tank 10. To prevent the sprayed liquid from dripping into the first tank 10 and affecting the acid concentration therein, this embodiment preferably provides a sealing cover 30 on the first tank 10. This sealing cover 30 is pushed by a drive mechanism 60 and reciprocates from the rear of the first tank 10 towards its opening. The direction of movement of the sealing cover 30 is independent of the length of the spray pipe; its position is determined based on the layout space of the equipment. Figure 1 For example, in this embodiment, if there is sufficient space in the front-to-back direction of the first tank 10, the sealing cover 30 is set to move in the same direction as the length of the spray pipe. If there is sufficient space in the left-to-right direction of the first tank 10, the sealing cover 30 is set to move along the left-to-right direction of the first tank 10. This embodiment accurately controls the moving time of the sealing cover 30 and the time when the ultra-thin glass leaves the first tank 10. When the ultra-thin glass is processed in the first tank 10 and begins to move upward, the sealing cover 30 is controlled to start moving to cover the first tank 10, so that the first tank 10 can spray the ultra-thin glass immediately after sealing, thereby reducing the acid concentration on the ultra-thin glass as quickly as possible.

[0042] Furthermore, the spray nozzle 41 is a mist spray nozzle 41. The surface treatment equipment in this embodiment is applied to ultra-thin glass, which is generally less than 0.1 mm thick. Therefore, during the corresponding operation, it is necessary to ensure that the glass will not be damaged or suffer other adverse conditions due to unnecessary stimulation. The operation of the spray assembly 40 in this embodiment to spray the ultra-thin glass to reduce the acid concentration also needs to ensure that the spray water is not too strong and will not affect the glass itself. Preferably, a mist spray nozzle 41 is used to spray pure water onto the ultra-thin glass in the form of a spray. While reducing the acid concentration, the water mist has little impact on the glass.

[0043] Optionally, the top surface of the sealing cover 30 is an inclined surface that is higher in the middle and lower on the sides.

[0044] refer to Figure 1 or Figure 2As shown, in this embodiment, the top surface of the sealing cap 30 is inclined. When pure water is sprayed from the spray pipe onto the ultra-thin glass 50 to dilute the acid solution on the ultra-thin glass 50, liquid dripping may occur. To prevent liquid from flowing into the first tank 10 when the sealing cap 30 is opened and affecting the acid concentration in the first tank 10, the sealing cap 30 is preferably designed to be higher in the middle and lower on both sides, facilitating rapid liquid flow. Furthermore, a groove for water storage and drainage (not shown in the figure) can be provided at the top of the sealing cap 30 to collect the dripping liquid and discharge it through the groove to the corresponding recovery pipeline for discharge treatment.

[0045] Furthermore, it also includes a water tank, which is connected to the spray assembly 40 and supplies water to the spray assembly 40. In this embodiment, a water tank (not shown in the figure) is provided to supply water to the spray assembly 40.

[0046] In this embodiment, the second tank 20 and the subsequent third tank contain cleaning solutions, generally using pure water for cleaning. The ultra-thin glass is taken out from the first tank 10 and placed into the second tank 20 and the subsequent third tank for soaking and cleaning (only the first tank 10 and the second tank 20 are shown in the figure). After a period of time, the pure water in the second tank 20 and the third tank is replaced.

[0047] In this embodiment, a drive assembly is used to move the cartridge that prevents the ultra-thin glass from moving. The figure only shows the part of the drive assembly used to hook the cartridge structure; other drive parts are not shown.

[0048] The surface treatment equipment provided in the above embodiment adds a spray assembly 40 above the first acid tank. When the ultra-thin glass leaves the acid tank, the spray assembly 40 sprays pure water to dilute the acid on the glass, so that no bad marks appear on the bottom of the ultra-thin glass, thus improving the quality of the product.
