Description

Technical Field

[0001] The utility model relates to the technical field of screen assembly production auxiliary devices, in particular to an auxiliary device for disassembling an OCA optical adhesive bonded screen. Background Art

[0002] OCA optical adhesive is an optical-grade acrylic-based adhesive primarily used for bonding optical components such as touch screens and display screens. Due to its excellent optical properties, thermal stability, and weather resistance, OCA optical adhesive has become recognized in the optical display industry as one of the best adhesive materials for touch screens.

[0003] However, during the OCA assembly process, touch screens may experience defects such as bubbles and foreign matter. These defective products require disassembly and rework. Currently, hot and cold disassembly are commonly used for OCA-bonded screens. Hot disassembly is less likely to damage the screen, but it is inefficient and damages the OCA adhesive, making it difficult to remove and recycle the touch screen. Therefore, cold disassembly is widely used in the industry for its low cost, high efficiency, and convenient OCA adhesive removal, facilitating touch screen recycling.

[0004] However, cold disassembly requires relatively high disassembly skills, is slow, and is prone to damaging the screen during the disassembly process, resulting in increased costs. Therefore, there is an urgent need to design a device that can assist employees in disassembly. Summary of the Invention

[0025] The technical solution of the present utility model is described in detail below with reference to the accompanying drawings and embodiments.

[0026] See Figure 1 and Figure 2 As shown, the embodiment of the present application provides an auxiliary device for disassembling an OCA optical adhesive bonded screen, including:

[0027] The handheld board 1 includes an integrally arranged head portion 11 and a handheld portion 12;

[0028] A raised rib 2 is provided on the outer end of the head 11 and extends in a direction parallel to the surface of the handheld board 1;

[0029] The limiting plate 3 is detachably connected to the head 11;

[0030] Among them, after the lifting rib 2 extends into the bonding part of the screen until the screen presses the limiting plate 3, the handheld board 1 is turned over to lift the screen for disassembly.

[0031] When disassembling the OCA bonded screen, after the screen is cold-disassembled before processing, the lifting rib 2 is extended into the bonding part of the screen and limited by the limit plate 3. Then, the handheld board 1 is flipped over to lift the screen for re-disassembly. One end of the screen can be lifted and detached, and the screen can be disassembled smoothly, quickly and intact, thereby reducing the disassembly scrap rate, improving the re-disassembly yield and efficiency, and is practical and convenient.

[0032] In this embodiment, the cold disassembly pre-processing operation is: first cut the OCA with a molybdenum wire, and then put the screen into a freezer for freezing. This operation is a common existing technology in this field and will not be described in detail again.

[0033] Furthermore, a disassembly structure 4 is provided between the limiting plate 3 and the head 11 .

[0034] Specifically, the disassembly and assembly structure 4 includes a plurality of first connecting threaded holes 41 opened on the head 11, and second connecting threaded holes 42 opened on the limiting plate 3 and arranged corresponding to the first connecting threaded holes 41. The first connecting threaded holes 41 and the second connecting threaded holes 42 are connected by screws or bolts.

[0035] During assembly, the limiting plate 3 is stacked on the head 11 of the handheld plate 1, and then moved to align the first connecting threaded hole 41 with the second connecting threaded hole 42 accordingly, and then the first connecting threaded hole 41 and the second connecting threaded hole 42 are threadedly connected respectively by screws or bolts, so that the limiting plate 3 and the handheld plate 1 are fixedly assembled together, which is practical and convenient.

[0036] In this embodiment, the position of the first connecting threaded hole 41 can also be opened according to the specific installation position of the limiting plate 3, which is practical and convenient.

[0037] Furthermore, the handheld plate 1 and the raised rib 2 are integrally provided, which facilitates processing and production.

[0038] Specifically, the head 11 is in the shape of a long strip.

[0039] The hand-held portion 12 is in the shape of a handle, which is convenient for employees to hold and operate.

[0040] The limiting plate 3 is arranged in the shape of a dumbbell bar.

[0041] Furthermore, the distance between the side wall of the limiting plate 3 close to the warping rib 2 and the outermost end of the warping rib 2 is L, wherein the value of L ranges from 10 to 15 mm.

[0042] In this embodiment, preferably, the value of L is 11 mm.

[0043] Furthermore, the thickness of the raised rib 2 is less than the thickness of the handheld board 1. This facilitates the raised rib 2 to smoothly extend into the screen bonding portion, which is practical and convenient.

[0044] Furthermore, the hand-held portion 12 is further provided with an anti-drop protrusion 120 at one end away from the head 11. By providing the anti-drop protrusion 120, it is prevented that the employee's hand slips off the hand-held portion 12 and falls off when the hand-held board 1 is rotated, which is practical and convenient.
