Mobile terminal disassembly equipment

Abstract

To provide a mobile terminal disassembly device that enables a mobile terminal to be safely and efficiently disassembled into a display part and a housing part. [Solution] The mobile terminal disassembly device 1 has a heating unit 3 that heats at least a portion of the outer edge of the mobile terminal to be disassembled, thereby reducing the adhesive strength of the adhesive layer interposed between the display portion and the housing portion. The heating unit 3 is configured to heat, for example, three sides of the outer edge of the display side of the mobile terminal. When performing the disassembly process, the worker presses down one end of a lever 15. As a result, the movement of the lever 15 is transmitted to the tip of a movable portion 13 to which an upper suction pad 9 is fixed, causing the movable portion 13 to rotate. This rotation action pulls the housing portion of the mobile terminal, which is adsorbed by the upper suction pad 9, diagonally upward, and the mobile terminal is forcibly disassembled into a display portion (lower portion) and a housing portion (upper portion).

Description

[Technical Field]

[0001] The present invention relates to a disassembly device used to disassemble mobile terminals (personal digital assistants) such as tablet terminals and smartphones. [Background technology]

[0002] In recent years, mobile devices such as tablets and smartphones have become widely used in educational settings and for business purposes, and these devices are subject to disposal after a certain period of use. In particular, educational devices deployed in elementary, junior high, and high schools nationwide under the Ministry of Education, Culture, Sports, Science and Technology's GIGA School Initiative require large-scale disposal when they reach the time for replacement, and establishing a method for safely and efficiently disposing of these devices has become a challenge.

[0003] However, mobile devices to be disposed of contain storage media (SSDs, etc.) that contain highly confidential data such as personal information, business information, and intellectual property information, as well as built-in batteries such as lithium-ion batteries that pose a risk of fire and explosion, and disposing of the device while these devices are still inside carries serious risks such as information leaks and fires. Therefore, from the perspective of safety and information security, it is necessary to disassemble the mobile device before disposal and properly remove storage media such as SSDs and batteries installed in the casing.

[0004] Conventionally, the disassembly method for discarding mobile terminals has been to heat the entire surface of the terminal to melt and soften the adhesive layer (the adhesive that bonds the display part to the housing part), thereby separating the display part from the housing part. For example, a common configuration is to heat the entire front of the terminal using a heating plate or the like.

[0005] However, with this type of full-surface heating method, there is a risk that the heat will affect the lithium-ion battery inside the casing, potentially causing serious safety issues such as overheating, fire, or explosion.On the other hand, if heating is done carefully to avoid full-surface heating, or if the display section is separated solely by hand, the disassembly process can take a lot of time and effort, posing a challenge in terms of work efficiency, especially in workplaces where a large number of mobile devices need to be processed. Summary of the Invention [Problem to be solved by the invention]

[0006] In view of the above-mentioned problems, an object of the present invention is to provide a mobile terminal disassembly device that enables a mobile terminal to be safely and efficiently disassembled into a display portion and a housing portion. [Means for solving the problem]

[0007] The above-mentioned object is to provide a disassembly device used for disassembling a mobile terminal, This is achieved by a mobile terminal disassembly device that has a heating section for heating at least a portion of the outer edge of the mobile terminal to reduce the adhesive strength of the adhesive layer interposed between the display section and the housing section.

[0008] In the mobile terminal disassembly device, the heating unit is configured to heat at least three sides of the outer edge portions of one and / or both sides of the mobile terminal.

[0009] In the mobile terminal disassembly device, the heating unit may be configured to heat one or more of one to four sides of the outer edge of one and / or both sides of the mobile terminal.

[0010] The mobile terminal disassembly device may further include a positioning unit that positions the mobile terminal in a predetermined position during disassembly.

[0011] In addition, the mobile terminal disassembly device a holding means for holding one of a display portion and a housing portion of the mobile terminal during disassembly; a separating means for moving the other of the display portion and the housing portion in a separation direction (to peel the other from the held one) while the holding means holds the other; may further comprise:

[0012] In the mobile terminal disassembling device, the holding means may include a lower suction portion configured to be able to be sucked onto the display portion or the housing portion.

[0013] In the mobile terminal disassembly device, the separating means an upper suction portion configured to be able to be adsorbed to the display portion or the housing portion; a movable section including an upper suction section of the separating means, the upper suction section being movable in a direction away from the lower suction section; It is possible to configure the system by including:

[0014] In the mobile terminal disassembling device, the movable portion of the separating means can be configured to be movable in a direction to obliquely pull up the display portion or the housing portion that is attracted to the upper attracting portion.

[0015] The mobile terminal disassembling device may further include a lever for operating the movable portion of the separating means by lever principle. [Effects of the Invention]

[0016] The mobile terminal disassembly device of the present invention is configured to heat at least a portion of the outer edge of the mobile terminal, which weakens the adhesive strength of the adhesive layer between the display part and the housing part, making it possible to safely and efficiently separate the display part and the housing part of the mobile terminal. This minimizes the thermal impact on built-in batteries such as lithium-ion batteries compared to conventional methods of heating the entire side of a mobile device, enabling safer disassembly work that avoids risks such as fire or explosion. Furthermore, by limiting the heating target to the minimum necessary outer edge, advantages such as shorter heating time, reduced power consumption, and simplified device configuration are obtained, which also contribute to improved work efficiency and economy. Furthermore, this invention is particularly useful in situations where both efficiency and safety in processing are required, such as the mass disposal of terminals under the GIGA School Project.

[0017] In addition, according to the present invention, the heating unit is configured to heat at least three sides of the outer edge of one and / or both sides of the mobile terminal, or to be able to select and heat any one to four sides, thereby making it possible to efficiently heat only the minimum area necessary for decomposition. This reduces power consumption by avoiding unnecessary heating and shortens heating time, making it possible to significantly shorten the time required to disassemble each mobile device. In addition, the heating unit does not need to be overly complicated, which improves the reliability and maintainability of the device.

[0018] In addition, according to the present invention, by providing a positioning section that reliably places the mobile terminal in a predetermined position when disassembled, the heating section can be accurately abutted against the outer edge of the mobile terminal, preventing uneven or insufficient heating. This ensures stable melting and softening of the adhesive layer, improving the reliability and safety of disassembly. In addition, since workers do not need to visually align the mobile device each time, work variations are reduced, and the speed and quality of the disassembly process are stabilized. Furthermore, in places where large numbers of devices are processed, such as in the GIGA School Project, this technology is useful for improving the efficiency of the entire disassembly process, as it simplifies the alignment work required each time.

[0019] In addition, according to the present invention, by providing a holding means for holding one of the display part and the housing part, and a separation means for separating the other while in this held state, it becomes possible to reliably and quickly separate the display part and the housing part from a state in which the adhesive strength has been reduced by heating. This allows the disassembly process to proceed reliably even when the adhesive remains strong by fixing one side and forcibly separating the other. This also contributes to improving work efficiency and disassembly quality in workplaces where a large number of mobile devices are handled.

[0020] In addition, according to the present invention, the holding means is configured to include a lower suction portion that can be adsorbed to the display portion or the housing portion, making it possible to start the disassembly process while the mobile terminal is held stably on the device. In addition, the lower suction part eliminates the need for the worker to hold the terminal with their hand, improving work efficiency and contributing to ensuring safety. Therefore, this configuration has the practical effect of stably ensuring the speed, accuracy, and safety of disassembly work, even in sites where a large number of mobile terminals are processed continuously.

[0021] In addition, according to the present invention, the separation means is configured to include an upper suction portion that can be adsorbed to the display portion or the housing portion, and a movable portion that can move the upper suction portion in a direction away from the lower suction portion, making it possible to reliably separate the display portion and the housing portion under certain conditions with high reproducibility.

[0022] In addition, according to the present invention, the movable part of the separation means is configured to move in a diagonal direction to pull up the display part or housing part that is attracted by the upper suction part, so that force can be applied to the adhesive layer at an angle that makes it easy to peel it off, making the separation operation smoother and more reliable. In particular, even if the adhesive layer is firmly attached, pulling it up at an angle can more efficiently promote peeling of the adhesive layer than peeling it straight up in the vertical direction.

[0023] In addition, according to the present invention, the movable part of the separating means is provided with a lever for operating using the "leverage principle," so that the separating operation can be carried out smoothly with little force. This allows the display portion and the housing portion to be separated reliably and efficiently after the adhesive strength has been reduced by heating, significantly reducing the burden on the worker.

DETAILED DESCRIPTION OF THE INVENTION

[0025] The mobile terminal disassembly device of the present invention is a disassembly device used to disassemble various mobile terminals (personal digital assistants) such as tablet terminals and smartphones. In mobile terminals such as tablet terminals and smartphones, the display portion and the housing portion are bonded together using a strong adhesive to ensure waterproofing and improve rigidity, making them difficult to separate. (The adhesive bonded portion is referred to as the "adhesive layer" in this application.) Therefore, the mobile terminal disassembly device of the present invention aims to safely and efficiently disassemble mobile terminals with such adhesive structures, and is designed to achieve disassembly by applying heat to the adhesive layer (adhesive) that bonds the display part and the housing part, thereby weakening the adhesive strength. The embodiment described below is merely an example, and the mobile terminal disassembly device of the present invention is not limited to this. For example, it is possible to omit the suction part, movable part, lever, etc., which will be described later, and configure it as a device dedicated to heating.

[0026] The specific configuration of the mobile terminal disassembly device of the present invention will be described below with reference to the accompanying drawings.

[0027] (Configuration of mobile terminal disassembly device) The mobile terminal disassembly device 1 of this embodiment mainly includes: a heating unit 3 that heats the outer edge of the mobile terminal to be disassembled to melt and soften the adhesive layer; a positioning unit 5 for positioning the mobile terminal in a predetermined position when the mobile terminal is disassembled; a lower suction portion 7 and an upper suction portion 9 that are attached to the upper and lower surfaces of the mobile terminal when disassembled; a movable part 13 for forcibly moving the upper suction part 9 in a direction away from the lower suction part 7; A lever 15 that rotates the movable part 13 by the principle of leverage; a power switch 17 for supplying power to the decomposition device 1; The device main body 2 serves as a base for mounting the above-mentioned components. It has.

[0028] The specific configuration of each part of the mobile terminal disassembling device 1 will be described below.

[0029] The device body 2 is a base for holding and arranging the components that make up the entire mobile terminal disassembly device, and is provided with the rigidity and durability to ensure stable disassembly processing. The device body 2 incorporates the suction pads that make up the lower suction unit 7, the heating unit 3, the positioning unit 5, the movable unit 13, the lever 15, and other components, and is appropriately laid out so that these components operate functionally without interfering with each other. In addition, the device body 2 is provided with an inlet 21 (power input port) for connecting an external power source, as shown in Figure 3(b).

[0030] The heating unit 3 (heater) heats at least a portion of the outer edge of the mobile terminal to be disassembled, thereby reducing the adhesive strength of the adhesive layer between the display and the housing. In Figure 2, the U-shaped heat generation area generated by the heating unit 3 is indicated by hatching.

[0031] In this embodiment, the heating unit 3 is configured to heat three sides (i.e., two long sides and one short side) of the outer edge of the display-side surface of the mobile terminal. As a result, the heating unit 3 arranged in a U-shape applies heat intensively to a part of the adhesive layer, thereby reducing the adhesive strength efficiently and in a short time.

[0032] The heating temperature by the heating unit 3 is not particularly limited. For example, the outer edge of the mobile terminal can be heated in a temperature range of 100°C to 120°C. The heating temperature by the heating unit 3 can be adjusted. The heating time by the heating unit 3 is not particularly limited, and can be, for example, several tens of seconds (approximately 20 to 30 seconds).

[0033] The heating location of the mobile terminal by the heating unit 3 is not limited to the above-mentioned embodiment. That is, the heating unit 3 can be configured to heat at least three sides of the outer edge of one and / or both sides of the mobile terminal. Alternatively, the heating unit 3 can be configured to heat one or two of the first to four sides, or all four sides, of the outer edge of one and / or both sides of the mobile terminal. This configuration allows for flexible heating control depending on the target model and the state of adhesion.

[0034] The positioning unit 5 is configured to accurately position the mobile terminal in a predetermined position when disassembling. As shown in Fig. 1(a), the positioning unit 5 includes two fixed guides 51 and 52 and one movable guide 53.

[0035] In this embodiment, the mobile terminal can be placed in a predetermined position in a stable posture by placing the display surface of the mobile terminal facing downward and placing three sides of the mobile terminal against guides 51, 52, and 53 of device main body 2. Movable guide 53 is provided with handle 54, and by pushing and moving handle 54, the worker can easily adjust the position according to the dimensions and shape of the mobile terminal to be disassembled. By holding the mobile terminal in an accurate position by positioning unit 5, the relative positional relationship with heating unit 3 and suction units 7 and 9 is appropriately maintained, making it possible to improve the accuracy and stability of the heating process and decomposition process.

[0036] The lower suction part 7 serves as a "holding means" that adheres to the display surface of the mobile terminal during disassembly and holds the mobile terminal so that it does not move. Note that the lower suction part 7 may also adhere to and hold the housing surface of the mobile terminal during disassembly (turning it upside down).

[0037] In this embodiment, the lower suction portion 7 is composed of suction pads provided on the device main body 2. The suction pads constituting the lower suction portion 7 are arranged to face the suction pads of the upper suction portion 9 in the vertical direction. Note that although only the upper suction portion 9 is shown in the plan view of Fig. 1, the lower suction portion 7 is arranged directly below it.

[0038] The mobile terminal disassembly device 1 is also provided with a lower suction unit control switch 23 that controls the suction operation of the lower suction unit 7. The suction operation begins when the lower suction unit control switch 23 is turned on while the mobile terminal is lightly pressed against the lower suction unit 7 (suction pad). This creates a negative pressure inside the suction pad, and the pressure difference with atmospheric pressure firmly suctions the bottom surface (display surface) of the terminal. This vacuum suction principle allows the mobile terminal to be held stably, reliably preventing the mobile terminal from shifting or floating up during the disassembly process. The negative pressure required for suction can be generated, for example, by an electric vacuum pump connected to the device main body 2.

[0039] There is no particular limitation on the number of suction pads that make up the lower suction portion 7. In this embodiment, the number of suction pads provided is the same as that of the suction pads in the upper suction portion (three).

[0040] The movable part 13 equipped with the upper suction part 9 serves as a "separation means" that pulls up the housing part of the mobile terminal (the housing part that is sucked by the upper suction part 9) in a direction away from the display part. Note that the display part of the mobile terminal may also be pulled up in the opposite direction (by placing it upside down) in a direction away from the housing part.

[0041] In this embodiment, the movable part 13 is configured by an L-shaped member equipped with an upper suction part 9, and one end of the L-shaped member is rotatably attached to a movable part support base 32 via a rotation shaft 31. The movable part support base 32, which rotatably supports the movable part 13, is fixed to the device body 2 by a support base fixing screw 33, as shown in FIG.

[0042] The movable portion 13 having the above-described configuration is rotated via a lever 15 .

[0043] The upper suction part 9, which is a part of the separating means, is configured to be able to be attached to the surface of the housing of the mobile terminal. The upper suction part 9 is fixed to a movable part 13, which is also a part of the separating means. The movable part 13 is configured to be able to move the upper suction part 9 in a direction away from the lower suction part 7.

[0044] In this embodiment, the upper suction portion 9 is composed of suction pads provided on the movable portion 13. The suction pads constituting the upper suction portion 9 are arranged at positions facing the suction pads of the lower suction portion 7 in the vertical direction.

[0045] The suction operation begins when the upper suction unit 9 is lightly pressed against the surface of the mobile terminal's housing and the upper suction unit control switch 24 is turned on. This creates a negative pressure inside the suction pad of the upper suction unit 9, and the pressure difference with atmospheric pressure firmly suctions the top surface of the terminal (housing surface). This vacuum suction principle ensures that the housing parts are securely held during the separation process, and even if the adhesive strength of the adhesive layer remains, it is possible to accurately peel off the housing parts while maintaining a stable suction state. The negative pressure required for suction can be generated, for example, by an electric vacuum pump connected to the device main body.

[0046] There is no particular limitation on the number of suction pads that make up the upper suction portion 9. In this embodiment, the number of suction pads provided is the same as that of the suction pads in the lower suction portion (three).

[0047] The lever 15 serves to operate the movable part 13 of the separating means by the principle of leverage. In this embodiment, lever 15 is a separate member rotatably attached to the tip end of an L-shaped member that constitutes movable part 13, and when an operator presses it down, it applies a force that rotates movable part 13. Lever 15 is configured to be rotatable around a rotation axis provided in device main body 2 as a fulcrum, and when an operator presses one end of lever 15 downward, L-shaped movable part 13 rotates and upper suction part 9 moves diagonally upward.

[0048] In this way, by utilizing the principle of leverage, the operation of lifting the housing portion can be efficiently performed with a relatively small force.

[0049] Movable part 13 of the separation means is configured to be movable in a direction to diagonally pull up the casing part that has been sucked by upper suction part 9. In this embodiment, movable part 13 is rotatably attached to movable part support base 32 fixed to device main body 2 via rotation shaft 31, and is configured to rotate around this rotation shaft 31 as a fulcrum by pressing down lever 15. This allows the casing part that has been sucked by upper suction part 9 to be pulled up diagonally upward relative to device main body 2.

[0050] By using this diagonal pulling configuration, a tearing force can be applied not only to adhesive layers whose adhesive strength has been reduced by heating, but also to adhesive layer portions that have not been sufficiently melted or softened (adhesive layer portions that have not been heated).As a result, it is possible to reliably cut the entire adhesive layer, achieving a stable separation operation.

[0051] (Operation when disassembling using a mobile terminal disassembly device) Next, the operation of the mobile terminal disassembling device when disassembling the mobile terminal will be described.

[0052] First, the mobile device to be disassembled is placed lightly on the lower suction part 7 of the device body 2 with the display surface facing downwards. At this time, the mobile device is placed so that the outer edge of the display surface is positioned above the heating part 3 (see Figure 2) arranged in a U-shape, which allows efficient heating treatment of the specified three outer edges.

[0053] When setting the mobile terminal on the device main body 2, the mobile terminal is placed with the display face down so that two adjacent sides of the mobile terminal are pressed against two fixed guides 51, 52 provided on the device main body 2, and furthermore, the remaining side is positioned by pressing the movable guide 53 while sliding it from the front to the back.

[0054] Next, the worker gently presses down on the top surface of the mobile terminal to be disassembled to bring the display surface (bottom surface) into close contact with the lower suction part 7, and turns on the lower suction part control switch 23 to start the suction operation. This creates a negative pressure inside the lower suction part 7, and the pressure difference with atmospheric pressure causes the display part of the mobile terminal to be firmly suctioned from below.

[0055] Next, the movable part 13 is tilted toward the mobile terminal, and the upper suction part 9 (suction pad) is lightly pressed against the top surface of the housing part (the top surface of the set mobile terminal). In this state, when the upper suction part control switch 24 is turned on, a negative pressure is created inside the suction pad of the upper suction part 9, and the pressure difference with atmospheric pressure causes the housing part to be firmly suctioned from above. This stably holds the upper and lower components of the mobile terminal by suction, preparing them for the subsequent separation operation.

[0056] Next, the outer edges of the mobile terminal, i.e., two long sides and one short side on the display side, are heated by the heating unit 3. As a result, the adhesive layer between the display and housing parts melts or softens due to the heat, reducing its adhesive strength and making it easier to forcibly separate them in a later process.

[0057] Then, after a predetermined heating time (for example, several tens of seconds) has elapsed, the operator manually pushes one end of lever 15 downward, as shown in Fig. 5. As a result, the movement of lever 15 is transmitted to the tip of movable part 13, causing movable part 13 to rotate in a direction away from lower suction part 7. This rotational movement pulls the housing part that is adsorbed by upper suction part 9 diagonally upward, forcibly separating the display part from the housing part.

[0058] At this time, the diagonal pulling action exerts a tearing force on the adhesive layers whose adhesive strength has been reduced by the heat treatment, as well as on the remaining parts that have not been sufficiently melted or softened, making it possible to reliably cut all of the adhesive layers.

[0059] In this embodiment, only three sides of the outer edge of the mobile terminal are heated, and the remaining side is not heated, but in the separation operation of pulling up diagonally, the adhesive begins to peel off starting from the heated sides, and finally the unheated side remains. As a result, when the housing part is pulled up, the remaining adhesive layer is pulled in a concentrated manner, making it possible to accurately cut the adhesive layer on that side even without heating.

[0060] This configuration ensures sufficient separation performance without heating all four sides of the mobile device, contributing to shorter heating times and improved energy efficiency.

[0061] When the lever 15 is fully lowered, a spacer may be inserted between the separated display portion and the housing portion.

[0062] Then, once the portable terminal has been separated into the display portion and the housing portion, the upper and lower suction portion control switches 23 and 24 are turned off to release the suction by the suction portions 7 and 9.

[0063] Through the above-described operations, this device can quickly and reliably disassemble mobile devices to be disposed of, achieving both high work efficiency and safety, particularly in workplaces where a large number of devices need to be processed continuously.

[0064] (Other embodiments) The mobile terminal disassembly device of the above-described embodiment is equipped with a heating unit as well as an adsorption unit, a movable unit, a lever, etc., but this configuration is only an example, and the mobile terminal disassembly device of the present invention is not limited to this.

[0065] For example, it is possible to configure the device as a dedicated heating device by omitting components such as the suction unit, movable unit, and lever (components for peeling off the top surface of the mobile terminal). Such a decomposition device dedicated to heating can be configured, for example, with a device main body, a heating unit, a power switch, and the like. [Explanation of symbols]
