Description

Technical Field

[0001] The present invention relates to the technical field of disassembly jigs, and in particular to a flat screen disassembly jig and a use method thereof. Background Art

[0002] At present, the screen of electronic products is bonded to the shell of the electronic products by adhesives. To remove the screen from the shell, the existing screen removal tools mostly use a single hot air gun to heat the screen, and then manually disassemble the screen. The screen and the shell both have a large adhesive area. A large adhesive area can improve the bonding strength and improve the quality state, but at the same time it increases the difficulty of disassembly and replacement. During manual disassembly, the operator needs to use a hot air blower to aim at the position where the adhesive is set, soften the adhesive by heating to reduce the viscosity, and then press one end of the screen with one hand or a tool, and pry the screen and the shell apart at the other end to separate the screen from the shell. In the above operation process, because the worker first pries the screen from one corner when prying it apart, the force is applied at a single point, and the screen is easily damaged due to uneven force, improper operation, etc., which is not only inconvenient to operate, but also inefficient and the screen scrap rate is relatively high.

Step 3: The electric push rod 2 contracts, driving the heating strip to return, and the telescopic rod of the cylinder extends, sucking the suction cup onto the screen. The turntable drives the rotating shaft to rotate, which can make the bevel gear 1 drive the meshing bevel gear 2 to rotate, and then drive the screw 2 to rotate, which can make the threaded sleeve move toward the inside of the connecting plate, thereby driving the rubber plug to move, so that negative pressure is generated inside the suction cup, making the suction cup and the screen more closely adsorbed; Step 4: Start the cylinder telescopic rod to drive the connecting plate to move upward, which can drive the screen to move upward and separate from the flat panel.

[0014] The advantages of the present invention compared with the prior art are: The present invention places the tablet whose screen needs to be disassembled between two positioning posts, first determines the two sides of the tablet, the positioning posts slide in the slide groove, one end of the second spring is connected to the inner wall of the slide groove and the other end is connected to the positioning posts, the elastic force generated by the extrusion of the second spring causes the positioning posts to clamp the base plate, at this time, the first screw is rotated to push the active plate to move, the active plate, two short driven plates and the long driven plate form a parallelogram, a limiting post connected to the base plate is installed between the two short driven plates, the short driven plate can rotate around the limiting post, and the long driven plate will approach the active plate, so the other two sides of the tablet are tightened to fix tablets of different sizes.

[0015] The extension of the second electric push rod causes the heating strip to move to the upper end of the flat plate, and the heating strip heats the colloid between the flat plate and the screen to be pyrolyzed. The extension of the first electric push rod drives the support to move toward the gap between the flat plate and the screen, and the sliding slider enlarges the gap between the screen and the flat plate. The second electric push rod contracts, driving the heating strip to return, and the cylinder telescopic rod extends to suck the suction cup onto the screen. Turning the turntable drives the shaft to rotate, which can cause the first bevel gear to drive the meshing bevel gear second to rotate, and then drive the second screw to rotate, which can cause the threaded sleeve to move toward the inside of the connecting plate, thereby driving the rubber plug to move, so that negative pressure is generated inside the suction cup, so that the suction cup and the screen are more closely adsorbed, and the cylinder telescopic rod is started to drive the connecting plate to move upward, which can drive the screen to move upward, thereby separating it from the flat plate. The force during disassembly will be more uniform, avoiding damage to the screen. BRIEF DESCRIPTION OF THE DRAWINGS
