Description

Technical Field

[0001] This utility model relates to the field of mobile phone glass processing technology, specifically a mobile phone glass processing device with ultra-alkali resistant protective oil. Background Technology

[0002] Super alkali-resistant protective oil is a coating material that can provide protection for glass surfaces. Glass protective oil is mainly used for the protection and masking of the surface processing of mobile phone glass covers. The product has good adhesion to glass and enables etching processing of mobile phone glass.

[0003] In practical use, mobile phone glass processing equipment often prints alkali-resistant protective ink on the glass surface. After drying, the unprotected areas are etched with an alkaline solution, and finally the protective layer is removed with an acidic deinking solution. However, existing alkali-resistant protective inks can only withstand 10%-20% NaOH solution, resulting in poor processing effects. At the same time, the squeegee in screen printing is usually fixed with screws, which increases the difficulty of installation and makes it difficult to flexibly and conveniently install and remove the squeegee, reducing the work efficiency during squeegee installation and removal and making it inconvenient to use.

[0034] The working principle of the ultra-alkali resistant protective oil mobile phone glass processing device provided by this utility model is as follows:

[0035] By placing the phone cover body 4 above the placement seat 3, and then rotating the screen printing frame plate 6 downwards to fix the screen printing frame plate 6 onto the phone cover body 4, the two limiting baffles 25 are then rotated onto the screen printing frame plate 6. Next, the two second inserts 26 are snapped into the screen printing frame plate 6 and the placement seat 3 to securely position the screen printing frame plate 6. Then, ultra-alkali resistant protective oil is applied to the screen printing frame plate 6. Finally, the controller 67 activates the electric push rod 23, causing the electric push rod 23 to drive the mounting seat 7 downwards, so that the inclined scraper 11 adheres to the screen... At point 6 of the screen printing frame, the controller 67 starts the servo motor, and the output shaft of the servo motor drives the lead screw 8 to rotate. In this way, the horizontal plate 9 on the lead screw 8 can drive the inclined scraper 11 to move and evenly print the super alkali-resistant protective oil on the mobile phone cover plate. At the same time, two locking posts 12 are inserted into the horizontal plate 9 and the inclined scraper 11 to initially lock and fix the inclined scraper 11. Then, two first insert rods 14 are locked into the locking posts 12 and the side plate 13 to further fix the inclined scraper 11. This locking method can improve the loading and unloading efficiency of the inclined scraper 11, saving time and effort.

[0036] The phone cover plate body 4, printed with ultra-alkali resistant protective oil, is removed and placed on the rack 17 in the heating chamber 15. The heating chamber 15 is then closed, and the controller 67 activates the nickel-chromium alloy heating wire 16 to heat the phone cover plate. It is pre-cured at 80°C for 10 minutes, then post-cured at 150°C for 30 minutes to form a dense cross-linked structure. The cured phone cover plate is then placed in the first pot 19 of the first oil bath 18, which contains a 50% NaOH solution. The controller 67 then activates the first oil bath 18, heating the 50% NaOH solution at 120°C for 60 minutes to etch the unprotected areas of the phone cover plate. The alkali-etched phone cover plate is then placed in the second pot 21 of the second oil bath 20, which contains a pH... A 10-12% alkaline deinking solution is used, and then the controller 67 starts the second oil bath 20, immersing the glass at 60℃ for 10 minutes to remove the protective layer. The entire process does not require strong acid, achieving efficient and environmentally friendly mobile phone glass etching.
