Mobile phone screen disassembly tool

Abstract

The invention provides a mobile phone screen disassembly tool. A left clamping block and a right clamping block are driven to move to the inner side synchronously until the left end and the right endof a mobile phone shell are clamped and fixed, then a suction cup is sucked at the lower end of a mobile phone screen, hot air blown out of a hot air gun is utilized to heat an adhesive strip at the lower end of the screen, a hand wheel II is rotated to drive a ratchet wheel and a cable guide wheel III to rotate, a pull rope pull the suction cup to pull the screen up under guiding of a cable guidewheel II and a cable guide wheel I, since connection between a pawl and the ratchet wheel is characterized by one-way rotation, the suction cup cannot move down, the handwheel II is rotated each timeto drive the ratchet wheel to rotate a ratchet clearance, thus the height of screen warping can be slowly controlled, a blade is utilized to cut an adhesive layer, the screen is separated from the shell slowly, finally flat cables are disassembled from a circuit board, and the mobile phone screen can be disassembled. The situation that the flat cables are broken due to overexerting manual operation is effectively avoided.

Description

technical field [0001] The invention relates to the technical field of mobile phone maintenance tools, in particular to a mobile phone screen disassembly tool. Background technique [0002] With the development of mobile phones, the current mobile phones generally adopt the form of a full screen. At the same time, the mobile phone adopts an integrated mechanism design and has a waterproof level of IP58, IP57 or even IP68. The circuit board can only be exposed after the body is removed, but due to the waterproof design, the screen is glued to the case by adhesive strips. Blow hot air, the hot air will heat and soften the rubber strip, and then pull the suction cup upwards to lift the screen. However, due to the current full-screen design of the mobile phone screen, an under-screen fingerprint module, infrared light sensor, structured light sensor, earpiece, speaker, etc. are integrated. Components, so the screen is connected to the circuit board through a cable. When disasse...

[0002] With the development of mobile phones, the current mobile phones generally adopt the form of a full screen. At the same time, the mobile phone adopts an integrated mechanism design and has a waterproof level of IP58, IP57 or even IP68. The circuit board can only be exposed after the body is removed, but due to the waterproof design, the screen is glued to the case by adhesive strips. Blow hot air, the hot air will heat and soften the rubber strip, and then pull the suction cup upwards to lift the screen. However, due to the current full-screen design of the mobile phone screen, an under-screen fingerprint module, infrared light sensor, structured light sensor, earpiece, speaker, etc. are integrated. Components, so the screen is connected to the circuit board through a cable. When disassembled, the force of pulling the suction cup is too large, causing the screen to lift too high and the cable to be broken, resulting in mobile phone failure.
