Description

Technical Field

[0001] The present invention relates to the technical field of screw disassembly, and more particularly to a special disassembly device for screws in a mobile terminal. Background Art

[0002] The main function of a screw is to connect two workpieces together for fastening. A screw is a tool that uses the physical and mathematical principles of the inclined plane circular rotation and friction of an object to gradually fasten mechanical parts of a device. A screw is a general term for fasteners and is an indispensable industrial necessity in daily life: such as extremely small screws used in cameras, glasses, watches, electronics, etc.; general screws used in televisions, electrical products, musical instruments, furniture, etc.; for engineering, construction, and bridges, large screws and nuts are used; for transportation tools, airplanes, trams, cars, etc., both large and small screws are used.

[0003] The screws in a mobile phone can usually be removed with a screwdriver or an electric screwdriver. However, when some screws are stripped, they cannot be removed by conventional methods. When using automated equipment to remove screws, in addition to considering stripped screws, special situations such as screws covered by obstacles and defective screws are usually encountered. The disassembly efficiency of abnormal screws also needs to be improved. At the same time, for example, the utility model patent with the publication number CN215546582U discloses an automated disassembly device for the bottom screws of a mobile phone, including a mobile phone fixture, a fixture moving mechanism, a screw cleaning mechanism, a vision mechanism, a screw disassembly mechanism, a disassembly moving mechanism, and a bottom plate; the vision mechanism includes a vision base plate, vision side plates, a camera base plate, a CCD camera, camera side plates, a camera top plate, a bracket, and a light source. Its structure is simple, it cannot perform cutting processing on abnormal screws in special situations, and it also lacks a tool changing mechanism. Therefore, the disassembly efficiency is not high. Summary of the Invention

[0051] Working principle: When disassembling the screws inside the mobile phone, the mobile phone is placed through the transverse movement mechanism. After being fastened by the fixing assembly, the mobile phone can be moved below the disassembling mechanism. After the cutting assembly processes the abnormal screws of the mobile phone, the mobile phone is transferred to the transmission mechanism by the transverse movement mechanism and limited by the blocking assembly. Under the action of the vision mechanism, it is detected whether the abnormal screws inside the mobile phone have been removed. After the removal is completed, the blocking assembly releases, and the mobile phone can be sent out by the transmission mechanism, greatly improving the success rate of automatic disassembly of the mobile phone. At the same time, when the cutting assembly is in use, the tool head can be replaced through the tool changing mechanism, so as to replace it in time after the sharpness of the original tool head decreases and does not meet the requirements. Through the suction nozzle and protective net provided on the cutting assembly, chips can be absorbed and the splashing of chips can be prevented, further improving the safety of the disassembly device.
