Disclosed is disassembly device for disassembling component such as touch display screen, the component comprising a first substrate and substrates which are arranged oppositely and between which adhesive is provided. The device comprises oppositely arranged two fixture mechanisms which fix the first substrate and the second substrate, respectively, and which can relatively move close to or away from each other. The device further comprises an adhesive processing mechanism, such that an adhesive force between the adhesive after processing and the first (and/or second) substrate is less than the adhesive force between the adhesive before processing and the first (and/or second) substrate. With the disassembly device according to the embodiments of the disclosure, the mutually attached first substrate and second substrate can be efficiently disassembled without damaging the first substrate and the second substrate.
