Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of terminal product screen quick disassembly, and particularly relates to a screen quick disassembly device. BACKGROUND

[0002] At present, the screen quick disassembly device of a terminal product such as a smart phone is mostly based on the principle of thermal softening-mechanical separation: a local area of an adhesive region at the edge of a screen is heated by a preheating block, a screen surface is fixed by a screen disassembly carrier such as a vacuum suction cup or a mechanical clamp, and then a precise blade or a thin wedge-shaped tool is vertically cut along a heating path by a screen disassembly assembly driven by a pre-set trajectory to separate the screen from a body, and this kind of method relies on the rigid contact of the blade and the heating area, and the linear pushing force is used to overcome the bonding strength of the adhesive and the frame to realize the automatic and quick disassembly of the screen.

[0003] However, the existing screen quick disassembly device relies on the direct confrontation of the blade normal pressure and the material hardness, which causes the mechanical contradiction of the tool and the screen interface to be difficult to reconcile, and makes the vertical cutting mode have some defects: firstly, the contact surface of the blade when vertically cutting is single-point static extrusion, which is easy to cause stress concentration when the local resistance suddenly increases, such as when the screen frame is made of titanium alloy, which easily causes the blade to collapse or the screen to crack; secondly, the linear pushing relies on the high torque output of the motor, which is easy to cause the pushing speed to be unstable due to the resistance fluctuation in the complex frame structure, forcing the system to frequently start and stop to correct the path, which in turn prolongs the disassembly time, and more importantly, the rigid vertical cutting is difficult to adapt to the cutting angle requirements of screens with different curvatures, which easily causes the display module to be unevenly layered due to the non-orthogonal force, and for this purpose, a screen quick disassembly device is proposed.

DETAILED DESCRIPTION

[0029] In order to further illustrate the technical means and effects adopted by the application to achieve the predetermined application purposes, the specific embodiments, structures, features and effects according to the application are described in detail below in combination with the drawings and preferred embodiments.

[0030] Please refer to Figures 1-8As shown, the embodiment provides a screen quick disassembly device, which comprises a rack 1, a screen disassembly assembly 2, a screen disassembly carrier 3 and a preheating block 4 mounted on the screen disassembly assembly 2, and a quick disassembly assembly 5 located below the screen disassembly carrier 3; the quick disassembly assembly 5 comprises a driving part 51, a rotary cutting part 52, an L-shaped support part 53, a connecting rod lifting part 54, a connecting part 55 and an arc-shaped guide part 56, the L-shaped support part 53 is hinged with the screen disassembly assembly 2, the driving part 51 is in transmission connection with the rotary cutting part 52 through a support plate 6, the support plate 6 is movably connected with the L-shaped support part 53 through the connecting rod lifting part 54, one end of the connecting part 55 is fixed to the L-shaped support part 53, the other end of the connecting part 55 is slidably arranged in an arc-shaped groove 561 of the arc-shaped guide part 56, the driving part 51 drives the rotary cutting part 52 to rotate, the connecting rod lifting part 54 makes the support plate 6 drive the rotary cutting part 52 to cut into the screen, the connecting part 55 slides along the arc-shaped groove 561, and the connecting part 55 drives the L-shaped support part 53 to rotate around the hinge point to adapt to the cutting angle adjustment of screens with different curvatures, wherein the rotary cutting part 52 adopts a circular motion to cut the screen, instead of the traditional vertical cutting, which helps to disperse the stress during cutting and reduce tool damage caused by stress concentration, in addition, the continuous rotary motion of the rotary cutting part 52 makes the cutting process more smooth, reduces the energy loss caused by resistance fluctuation, thereby improving the cutting efficiency, and by sliding the connecting part 55 along the arc-shaped groove 561, the L-shaped support part 53 can rotate around the hinge point, which enables the device to adjust the cutting angle according to the curvature of the screen, enhances the adaptability of cutting screens with different curvatures, in addition, the transmission connection of the driving part 51 with the rotary cutting part 52 through the support plate 6 and the design of the connecting rod lifting part 54 can realize precise control of the cutting process, ensuring the accuracy of cutting and the integrity of the screen, further, the design of the arc-shaped guide part 56 allows the connecting part 55 to slide in the arc-shaped groove 561, increasing the flexibility of the device, enabling it to adapt to screens of different sizes and shapes, since the contact mode of the cutting part with the screen is more gentle and can be adjusted according to the curvature of the screen, the risk of damage to the screen during disassembly due to improper operation is reduced, and finally the quick disassembly is realized.

[0031] The current screen quick disassembly device of terminal products such as smart phones is mostly based on the principle of thermal softening-mechanical separation: the preheating block 4 locally heats the adhesive area of the screen edge, the screen surface is fixed by the screen disassembly carrier 3 such as a vacuum suction cup or a mechanical clamp, then a precision blade or a thin wedge-shaped tool is vertically cut along the heating path by the screen disassembly assembly 2, the screen and the body are separated by the preset trajectory, this method relies on the rigid contact of the blade and the heating area, overcomes the bonding strength of the adhesive and the frame by linear pushing force, realizes automatic and quick disassembly of the screen, however, the current screen quick disassembly device relies on the direct confrontation of the blade normal pressure and the material hardness, which makes the mechanical contradiction of the tool and the screen interface difficult to reconcile, so that the vertical cutting mode has some defects: first, the contact surface of the blade when vertically cutting is single-point static extrusion, which is easy to cause stress concentration when encountering a titanium alloy screen frame, resulting in blade collapse or screen hidden cracks; second, linear propulsion relies on high torque output of the motor, which is easy to cause unstable pushing speed due to resistance fluctuation in complex frame structure, forcing the system to frequently start and stop to correct the path, which prolongs the disassembly time, more importantly, rigid vertical cutting is difficult to adapt to the cutting angle requirements of screens with different curvatures, which is easy to cause uneven layering of the display module due to non-orthogonal force.

[0032] To solve the above problems, in the embodiment, a rotating cutting part 52 is adopted, dynamic cutting is used instead of the traditional static vertical extrusion of the blade, local stress is dispersed by centrifugal force, the risk of blade collapse or screen hidden cracks is reduced, the L-shaped support part 53 is hinged with the screen disassembly assembly 2, the connecting part 55 slides along the arc-shaped groove 561 of the arc-shaped guide part 56, the L-shaped support part 53 rotates around the hinge point, the rotating cutting part 52 can automatically adjust the cutting angle according to the screen curvature, adapt to the cutting requirements of screens with different curvatures, avoid uneven layering caused by non-orthogonal force, the connecting rod lifting part 54 controls the depth and speed of the rotating cutting part 52 cutting into the screen by adjusting the lifting of the support plate 6, combines with the stable transmission of the driving part 51 to reduce the unstable pushing speed caused by resistance fluctuation, realizes continuous and stable cutting action, improves the disassembly efficiency, the preheating block 4 locally heats and softens the adhesive area of the screen, the screen surface is fixed by the screen disassembly carrier 3, which provides a stable working environment for the rotating cutting, further reduces the cutting resistance, through dynamic cutting, angle self-adaptive adjustment, resistance buffering and heating, the problems of tool damage, low efficiency and screen damage caused by rigid contact of the traditional device are solved.

[0033] When the terminal product such as a smart phone is made of high-strength material such as titanium alloy, the contact between the blade of the screen dismounting device and the screen interface is easy to cause local stress concentration, especially in the hard frame made of titanium alloy, which causes the blade to collapse or the screen to crack. In order to avoid this problem, in an embodiment, one end of the support plate 6 is hinged with the L-shaped support part 53, and the other end of the support plate 6 is connected with the connecting rod lifting part 54. Here, a lever structure is formed through the hinge point, the adjustment accuracy of the connecting rod lifting part 54 is amplified, and the controllability of the cutting depth of the rotary cutting part 52 is ensured. The hinge design allows the support plate 6 to move flexibly in the vertical and horizontal directions, avoiding stress concentration caused by rigid connection.

[0034] Since the resistance of the rotary cutting part 52 will suddenly increase from not cutting into the screen to cutting into the screen, and the rotary cutting part 52 needs to be driven by a motor, if the rotary cutting part 52 is directly driven by the motor, the resistance fluctuation is easy to cause the motor load to suddenly change, causing unstable speed or even shutdown. In order to avoid this problem, in an embodiment, the driving part 51 includes a driving part 511 arranged on one end of the support plate 6 and a support block 512 arranged on the other end of the support plate 6. A rotating shaft 513 is rotatably arranged on the support block 512. The rotating shaft 513 is in transmission connection with the driving end of the driving part 511. The rotary cutting part 52 is fixedly sleeved on the rotating shaft 513. The rotary cutting part 52 is a cutting wheel. The teeth of the cutting wheel are ladder teeth. The connection part 55 between adjacent two ladder teeth is divided into an arc structure. The driving part 511 and the rotating shaft 513 are connected by a belt transmission. The instantaneous resistance fluctuation is absorbed by the elasticity of the belt, reducing the impact on the motor, ensuring the stability of the cutting wheel speed, realizing smooth power transmission, and balancing the stress of the rotary cutting part 52, reducing vibration and structural deformation. The driving part 511 here is a motor. In addition, in the titanium alloy frame, the design of the ladder teeth increases the contact area between the cutting wheel and the adhesive. By replacing the traditional extrusion with shear force, the unit area pressure can be reduced. The adjacent ladder teeth are transitioned by an arc structure. The purpose is to optimize the stress distribution, avoid local stress exceeding the material strength, reduce the risk of tooth collapse, and the arc structure and the centrifugal force of the rotary cutting work together to further disperse the cutting stress and reduce the accumulation of friction heat.

[0035] In order to further reduce errors and improve cutting accuracy, in an embodiment, the connecting rod lifting part 54 includes a hinged rod 541, a sliding block 542 slidingly arranged on the L-shaped support part 53, a limiting block 543 arranged on the L-shaped support part 53, and a guide rod 544, both ends of the hinged rod 541 are hinged with the sliding block 542 and the support plate 6 respectively, the guide rod 544 penetrates the limiting block 543 and is connected with the sliding block 542, and the guide rod 544 is screwed with the limiting block 543, the guide rod 544 and the limiting block 543 are connected through threads, rotating the guide rod 544 can accurately control the displacement of the sliding block 542, realizing micron-level adjustment of the cutting depth, and the screwing structure has self-locking property, ensuring that the position of the sliding block 542 is fixed during cutting, preventing displacement deviation caused by vibration or resistance fluctuation, and it is to be noted that the adjustment of the guide rod 544 here and the adjustment of the arc-shaped plate below are both controlled by an electric control system, and the control of the electric control system belongs to mature prior art, which will not be described in detail here.

[0036] It is worth mentioning that since the screen of the terminal product such as a smart phone is disassembled, when the phone is fixed on the disassembly carrier 3, the quick disassembly assembly 5 is disassembled when the cutting wheel cuts into the titanium alloy phone frame, the titanium alloy has high hardness, the resistance rises sharply in the instant of contact, the instantaneous impact force is too large, and frequent impact will accelerate the wear of device components such as the hinge point and the sliding block 542, in order to solve this problem, in an embodiment, the hinge point of the hinged rod 541 and the support plate 6 is located below the support plate 6 at the support block 512, the sliding block 542 is an elastic sliding block 542, and a damping structure is formed between the hinged rod 541 and the sliding block 542, which is used to buffer the sudden change of resistance when the rotating cutting part 52 cuts into the screen, first, the hinge point is moved downward, the cantilever length of the support plate 6 is shortened, the moment of the cutting resistance on the hinge point is reduced, the risk of structural deformation is reduced, the cutting resistance is more directly transmitted to the L-shaped support part 53 and the arc-shaped guide part 56, rather than concentrated on the hinge point, the local stress is avoided to exceed the limit, the sliding block 542 is made of an elastic material such as polyurethane or silica gel, the instantaneous impact energy is absorbed through deformation of the sliding block 542 itself, the impact force transmitted to the cutting wheel and the screen is reduced, in addition, the sliding block 542 slides on the L-shaped support part 53, cooperates with the swing of the hinged rod 541, allows local elastic deformation and position fine adjustment, dynamically adapts to resistance changes, when the resistance suddenly increases, the elastic sliding block 542 is compressed and deformed, and at the same time, the hinged rod 541 slightly swings around the hinge point, forming a "spring-damping" system, quickly consuming impact energy, and then automatically resetting, the buffering effect of the elastic sliding block 542 avoids the cutting teeth of the cutting wheel from breaking due to too large instantaneous resistance, reduces the impact force on the screen, reduces the risk of hidden cracks, and allows the cutting part to slightly retreat or adjust the angle when the resistance suddenly changes, maintains the continuity of the cutting path, and avoids path deviation caused by jamming.

[0037] In order to enable the rotary cutting part 52 to better adapt to the angle, in an embodiment, the arc-shaped guide part 56 is an arc-shaped plate, and an arc-shaped groove 561 is arranged on the arc-shaped plate, the included angle of the arc-shaped groove 561 with the horizontal plane is greater than 15° and less than 30°, and the inclination angle of the arc-shaped groove 561 determines the rotation range of the L-shaped support part 53. The included angle range of 15°-30° enables the cutting part to cover the cutting angle requirement of the screen from the plane to the medium curvature screen. If the angle is too small, i.e. less than 15°, it will lead to insufficient rotation adjustment range and cannot adapt to the curved screen. If the angle is too large, i.e. greater than 30°, it may cause structural instability or cutting path deviation due to excessive rotation of the support part. By limiting the angle range, it is ensured that the cutting force is always applied along the tangent direction of the screen, avoiding damage to the display module caused by angle deviation. 15°-30° is an empirical optimization value, which can meet the curvature requirement of most screens and avoid excessive complexity of the structure. For the lower limit of 15°, it can adapt to common micro-curved screens and ensure the minimum effective adjustment range. The upper limit of 30° can adapt to high-curvature screens and prevent excessive rotation of the support part from causing mechanical interference or instability of the center of gravity.

[0038] In the above embodiment, the disassembly assembly 2 is provided with a through hole 21, the length of the through hole 21 is greater than 1.5 times and less than 2 times the diameter of the cutting wheel, and the width of the through hole 21 is greater than 2 times and less than 3 times the thickness of the cutting wheel. The length of the through hole 21 is greater than 1.5 times the diameter of the cutting wheel to ensure that the cutting wheel has enough longitudinal movement space when rotating and cutting in to avoid collision with the end of the through hole 21. The length is less than 2 times the diameter to prevent the through hole 21 from being too long to cause the local strength of the disassembly assembly 2 to decrease, especially the thin-walled structure, and the through hole 21 is too long to form a stress concentration area, which is easy to cause the disassembly assembly 2 to crack or deform. In addition, the lower limit of 1.5 times, the length of 1.5 times the diameter of the cutting wheel can cover the maximum displacement of the rotating track, for example, a cutting wheel with a diameter of 10 mm requires a through hole 21 with a length of at least 15 mm. The upper limit of 2 times, exceeding this value will cause the through hole 21 to occupy too much structural space, weakening the overall rigidity of the disassembly assembly 2, which is easy to fatigue failure under frequent stress working conditions. The narrow through hole 21 is easy to be blocked by cutting debris, affecting the movement of the cutting wheel. In order to avoid this problem, the width of the through hole 21 is greater than 2 times the thickness of the cutting wheel to provide sufficient lateral clearance to prevent the cutting wheel from contacting the side wall of the through hole 21 due to vibration or assembly error. A larger width allows the heat and debris generated during cutting to be discharged in time to prevent the adhesive from being cured again due to heat accumulation. The lower limit of 2 times, the width of 2 times the thickness of the cutting wheel can accommodate its dynamic swing and reserve a tolerance margin. The upper limit of 3 times, exceeding this value will significantly reduce the lateral support ability of the disassembly assembly 2, especially when cutting high-hardness materials, which may cause structural deformation. Finally, it needs to be pointed out that when the angle of the arc-shaped groove 561 is adjusted, the L-shaped support part 53 drives the cutting wheel to move in the through hole 21. The size of the through hole 21 needs to match the rotation and displacement requirements of the cutting wheel. The L-shaped support part 53 is an L-shaped support plate 6. For example, when the cutting wheel is inclined due to angle adjustment, the length of the through hole 21 needs to cover the projected track after inclination, and the width needs to accommodate the lateral swing. It needs to be pointed out that when the angle of the arc-shaped groove 561 is adjusted to the appropriate position, the locking block 7 and the arc-shaped plate can be limited by friction to make the connecting part 55 stable at the adjusted position.

[0039] The working principle and use process of the present application are as follows:

[0040] By replacing the static vertical extrusion of the traditional blade with the rotating cutting part 52, the centrifugal force generated by its dynamic cutting disperses the local stress, avoiding stress concentration caused by single-point contact. The rotating cutting part 52 rotates at a uniform speed under the drive of the drive part 51, combined with the local heating and softening of the screen edge adhesive area by the preheating block 4, reducing the cutting resistance. The L-shaped support part 53 is hinged to the screen disassembly assembly 2, and slides along the arc-shaped groove 561 of the arc-shaped guide part 56 through the connecting part 55, driving the support part to rotate around the hinge point, so that the cutting angle is automatically adjusted according to the screen curvature, ensuring that the cutting force is always applied along the tangent direction of the screen, avoiding uneven delamination caused by non-orthogonal force application. The connecting rod lifting part 54 precisely adjusts the displacement of the sliding block 542 through the screw guide rod 544, controls the lifting of the support plate 6, and realizes fine control of the cutting depth and speed. The shock-absorbing structure formed by the elastic sliding block 542 and the hinge rod 541 absorbs the instantaneous impact energy, buffers the sudden change in resistance, and protects the cutting wheel and screen interface;

[0041] In use, the terminal product, such as a smart phone, is fixed on the screen disassembly carrier 3, and the preheating block 4 is started to locally heat and soften the adhesive area at the edge of the screen. The drive part 51 drives the rotating cutting part 52 to rotate at high speed through belt transmission, while the connecting rod lifting part 54 adjusts the support plate 6 to descend, so that the cutting wheel contacts the screen. During the cutting process, the connecting part 55 slides along the arc-shaped groove 561 of the arc-shaped guide part 56, driving the L-shaped support part 53 to rotate around the hinge point, and automatically adjusting the cutting angle to match the screen curvature. The elastic sliding block 542 absorbs the instantaneous change in resistance by compression deformation, and the screw structure of the guide rod 544 and the limiting block 543 ensures the stability of the cutting depth. The cutting wheel continuously cuts along the preset path until the screen is separated from the body. After cutting is completed, the connecting rod lifting part 54 lifts the support plate 6, the cutting wheel is reset, and the debris in the through hole 21 is cleaned and the component state is checked for the next operation. Through the above process, efficient and low-loss screen disassembly is realized.

[0042] The above is only a preferred embodiment of the present application, and does not limit the present application in any form. Although the present application has been disclosed as above, it is not intended to limit the present application. Any person skilled in the art can make some changes or modifications to the above disclosed technical content without departing from the scope of the technical solution of the present application, and any equivalent embodiments with equivalent changes and modifications made to the above embodiments according to the technical essence of the present application are still within the scope of the technical solution of the present application.
