Description

Technical Field

[0001] The utility model belongs to the technical field of screen detachment and repair, and particularly relates to a screen detachment device. Background Art

[0002] Smartphones, tablets and the like are all electronic products used in daily life. Their screens are fragile and often need to be replaced. Therefore, maintenance personnel need to detach the broken screen from the main body and then replace it.

[0003] Currently, when detaching a broken screen from the main body, maintenance personnel need to fix one side of the main body on the loading platform, heat the main body to melt the glue that bonds the screen, then insert an optical glue separator into the gap on the side of the main body, and lift the screen of the main body to separate it from its body, thus completing the detachment of the screen. However, manually lifting the screen of the main body by maintenance personnel is difficult to grasp the turning amplitude for those with insufficient experience. When the lifting amplitude is too large, it may tear open the connected part of the glue that has not been dissolved yet, resulting in problems such as internal wire breakage. Summary of the Utility Model

Specific embodiments

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0020] The present invention provides a screen detachment device as Figures 1-4 shown, including:

[0021] A frame 1, a control panel 2 is provided at the front end of the frame 1, and a long board 3 is provided on the top surface of the frame 1. A bracket 4 is provided in the middle of the long board 3, and a fixing plate 5 for fixing a product is rotatably connected to the top of the bracket 4. Motor linear modules 6 are provided on the surface of the frame 1 and on both sides of the long board 3. A wire winding mechanism 7 for cutting the product fixed by the fixing plate 5 to separate the screen is provided on the surface of the motor linear module 6. The two wire winding wheels 8 of the wire winding mechanism 7 are respectively responsible for paying out and taking up the wire, so that when the two wire winding wheels 8 drive the wire to move, the screen on the surface of the fixing plate 5 can be accurately cut;

[0022] Tensioning frames 9, two groups of tensioning frames 9 are provided and are respectively arranged on the surface of the frame 1. Two groups of tensioning wheels 10 are rotatably connected to the surface of the tensioning frames 9. By passing the wire for paying out and taking up the wire by the wire winding wheels 8 between the two groups of tensioning wheels 10, when the two wire winding wheels 8 cooperate to wind the wire, the tensioning wheels 10 keep the wire in a taut state.

[0023] The wire winding mechanism 7 includes a moving plate 11 and a motor 12. The moving plate 11 is connected to the surface of the motor linear module 6, and one end of the moving plate 11 is slidably connected to a guide rail 13 provided on the surface of the long board 3. A motor bracket 14 is provided on the top surface of the moving plate 11, and the motor 12 is connected to the surface of the motor bracket 14.

[0024] The output end of the motor 12 is connected to the wire winding wheel 8. The tensioning frame 9 is connected to the surface of the moving plate 11, and a fine adjustment micrometer 15 is provided on the surface of the tensioning frame 9. The cutting depth and cutting position are calibrated and adjusted by the fine adjustment micrometer 15 to ensure that the cutting operation is more accurate.

[0025] On the surface of the frame 1 and on one side of the motor linear module 6, there is a drag chain 16 for wire routing. The drag chain 16 can effectively manage and protect the cables of the motor linear module 6, preventing them from being worn or wound due to frequent movement.

[0026] At the bottom of the long plate 3, there is a reduction motor 17, and the output shaft of the reduction motor 17 is connected to the fixed plate 5. The reduction motor 17 drives the product fixed plate 5 to rotate to achieve a certain angle, facilitating subsequent cutting. At the bottom of the fixed plate 5, there is a heating plate 18. On the surface of the fixed plate 5 and above the heating plate 18, there is a groove 19 for placing the product. On the surface of the groove 19, there are several mesh holes 20. When the heating plate 18 is heating, the heat can be transmitted to the product in the groove 19 through the mesh holes 20, thereby heating the product and softening the glue that bonds the screen to the product, facilitating subsequent cutting.

[0027] The motor linear module 6, the motor 12, the reduction motor 17, and the heating plate 18 are all electrically connected to the control panel 2. The PLC in the control panel 2 is used to intelligently control the motor linear module 6, the motor 12, the reduction motor 17, and the heating plate 18.

[0028] For this screen detachment device, the operator manually turns on the machine in advance and starts the heating plate 18 to work through the control panel 2 to preheat the fixed plate 5. After the preheating is completed, the operator places the product in the groove 19 on the surface of the fixed plate 5. The heat generated by the heating plate 18 can be transmitted to the product through the mesh holes 20, thereby heating the product and softening the glue that bonds the screen to the product, facilitating subsequent cutting;

[0029] Press the start button on the surface of the control panel 2 to start the suction cup (not shown in the figure) in the groove 19 to adsorb and fix the product. Then, the operator places the diamond wire at the incision of the product where the cutting is to start, and calibrates and adjusts the cutting depth and cutting position through the precision micrometer 15 to ensure that the cutting operation is more accurate. Then, start the two motors 12 to work. One of the two motors 12 rotates forward and the other rotates backward. Thus, the output shafts of the two motors 12 can drive the wire winding wheels 8 to rotate forward and backward. The two wire winding wheels 8 respectively wind and unwind the diamond wire. When the two wire winding mechanisms 7 cooperate with the wire winding, the tensioning wheel 10 combs the diamond wire and makes the diamond wire in a taut state, avoiding the state where the diamond wire sags. Then, through the operation of the two motor linear modules 6, drive the moving plate 11 to move slowly. Thus, drive the diamond wire on the surface of the wire winding wheel 8 to move through the moving plate 11 to cut the connection between the screen and the product, and simulate the forward and backward movement of the human hand to use the diamond wire to achieve the purpose of cutting and detaching the screen, so that the screen can be accurately detached from the main body, avoiding the problem of excessive manual lifting amplitude.

[0030] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
