(First embodiment)
Hereinafter, an example of the first embodiment of the present invention will be described with reference to the drawings. In the following description, description of components having the same configuration may be omitted.

  FIG. 1 is a diagram illustrating an example of the structure of a typical terminal device 200. The terminal device 200 is, for example, a portable information terminal such as a PC (Personal Computer), a tablet terminal, a smartphone, or a mobile phone. 1A is a top view of the terminal device 200, and FIG. 1B is a front cross-sectional view of the terminal device 200 taken along the line AB. The terminal device 200 includes a front plate 1, a housing 2, a display panel 3, an adhesive layer 4, a battery 5, and a circuit board 6. Further, in the top view of the terminal device 200 in FIG. 1A, a portion where an image is displayed is a display portion 7 and the other portion is a non-display portion 8.

  In the terminal device 200, the image displayed on the display panel 3 passes through the front plate 1 and is visually recognized by the user on the display unit 7. The housing 2 is made of, for example, metal or resin, and is bonded to the front plate 1 via the adhesive layer 4. In recent years, the terminal device 200 is generally configured such that the adhesive layer 4 is disposed inside the non-display unit 8, particularly around the display panel 3 (side) in order to reduce the thickness. Hereinafter, a contact surface between the front plate 1 and the housing 2 generated by the adhesive layer 4 will be described as an adhesive surface.

  An adhesive member such as a double-sided adhesive tape or an adhesive is used for the adhesive layer 4. The material used for the adhesive member generally has a characteristic that it softens when the temperature rises and the tensile shear strength decreases.

  FIG. 2 is a diagram illustrating a configuration example of the disassembling apparatus 100 according to the first embodiment. 2A is a top view of the disassembling apparatus 100, and FIG. 2B is a front view of the disassembling apparatus 100. FIG. Hereinafter, the directions orthogonal to each other parallel to the bonding surface between the front plate 1 and the housing 2 are the x direction (the right side in the drawing is the + x direction) and the y direction (the upper side in the top view is the + y direction). The direction orthogonal to each other will be described as the z direction (the upper side of the front view is + z direction). The disassembling apparatus 100 includes a component supply / removal unit BU, a heating / separation unit KU, a scraper unit SU, and a transport unit HU. The component supply / removal unit BU, the heating / separation unit KU, and the scraper unit SU share the front plate side base 40.

  The component supply / removal unit BU has an alignment member 31. The alignment member 31 is a member protruding in the + z direction shown in FIG. 2B from the front plate side base 40 and is used for alignment of the terminal device 200. The terminal device 200 is placed so that the end portion of the terminal device 200 is in contact with the alignment member 31 in a state where the front plate 1 faces downward with respect to the component supply / removal unit BU.

  The heating / separation unit KU includes a heating unit 10 with a holding function. A plurality of holes 9 are dispersedly arranged on the surface in contact with the terminal device 200 so that the heating unit 10 with a holding function can be applied to the terminal devices 200 having different sizes. The number of the holes 9 may be one as long as it has a predetermined adsorption capacity. The heating unit 10 with a holding function is connected to a separately prepared vacuum pump. And the control part of the separation apparatus 100 mentioned later drives the said vacuum pump, and sucks air from the hole 9, By this, the front plate 1 of the terminal device 200 is adsorbed to the lower surface of the heating part 10 with a holding function, and the front plate 1 Hold the whole.

  Further, the heating unit 10 with a holding function includes a heating device such as a hot plate that performs heating using resistance heating, a far-infrared heater, a hot air heater, a high-frequency heater, and the like, and heats the front plate 1 under the control of the control unit. To do. Although the heating device of the present embodiment is set to have a constant temperature, it may be set to a predetermined temperature profile.

  In addition, the decomposition apparatus 100 has a timer to be described later, and measures the time during which the heating unit 10 with a holding function heats the front plate 1. The control unit controls the heating unit 10 with a holding function to heat the front plate 1 for a predetermined time, and then stops the heating.

  The scraper unit SU includes a scraper 13 and a scraper slide unit 32. The scraper slide unit 32 holds the scraper 13 slidably in the ± x directions indicated by arrows in FIG. The slide unit 32 has a drive mechanism, and the control unit controls the operation of the drive mechanism, thereby moving the scraper 13 in the −x direction. Thereby, it becomes easy to insert the scraper 13 between the front plate 1 and the casing 2 of the terminal device 200 placed on the heating unit 10 with a holding function. Due to the pressure applied by the scraper 13 to the adhesive layer 4, the adhesive layer 4 itself is divided, or the adhesive force (adhesive strength of the adhesive layer) of at least one adhesive surface of the front plate 1 and the housing 2 is weakened and peeled off. The front plate 1 and the housing 2 are separated.

  The drive mechanism of the slide unit 32 can be realized by a mechanism including, for example, a motor, a gear, a rail, and the like. The scraper 13 is pre-aligned at a height (z direction) that can be inserted between the front plate 1 and the housing 2 after movement, but the height is set in advance for each model of the terminal device 200. The versatility may be further improved by recalling the stored contents and changing the height by calling the stored contents.

  The transport unit HU includes a housing side base 41, a housing slide unit 33, a housing holding unit 11, and a movable unit 12. In FIG. 2A, the casing base 41 is not shown for convenience of explanation.

  The housing slide unit 33 holds the movable portion 12 so as to be slidable in the ± x directions. The movable unit 12 has a drive mechanism, and the control unit controls the operation of the drive mechanism, so that the movable unit 12 slides in the ± x direction along the housing slide unit 33. Moreover, the movable part 12 enables the housing holding part 11 to move up and down in the ± z directions. The control unit controls the operation of the drive mechanism of the movable unit 12, thereby moving the housing holding unit 11 up and down between the component supply / removal unit BU and the heating / separation unit KU to convey the terminal device 200. At the same time, in the state where the front plate 1 is held by the heating unit 10 having a holding function of the heating / separation unit KU, the front plate is moved relative to the case 2 by moving the case holding unit 11 upward. Apply a force to peel the housing 2 from 1.

  The housing holding part 11 has one or a plurality of holes 9 on the surface in contact with the terminal device 200. Similarly to the heating unit 10 with a holding function, the housing holding unit 11 is connected to, for example, a separately prepared vacuum pump, and the control unit drives the vacuum pump to suck in air from the hole 9, whereby the terminal device 200. The case 2 is adsorbed. In this embodiment, a so-called vacuum chuck that holds an object by negative pressure is used for the holding mechanism of the heating unit 10 with a holding function and the holding mechanism of the housing holding unit 11. The mechanism is not limited to this. For example, another chucking mechanism such as an electrostatic chuck or a clamp mechanism that holds and holds a component with a jig (so-called clamper) may be used.

  Further, in the present embodiment, the casing holding unit 11 is arranged on the upper side and the heating unit 10 with a holding function is arranged on the lower side, but it may be arranged upside down. In this case, the terminal device 200 is also turned upside down and placed on the component supply / removal unit BU with the front plate 1 facing upward, and the movable portion 12 has a holding function that sucks the top plate 1 of the terminal device 200. The heating unit 10 is moved in the ± x direction and the ± z direction.

  Moreover, in this embodiment, from the point of the battery protection arrange | positioned at the back surface side of a housing, only the front plate 1 is heated with the heating part 10 with a holding function, but when it is not necessary to consider battery protection. The case holding unit 11 may heat only the case 2 using a heater or the like, or may heat the case 2 in parallel with heating the front plate 1.

  In addition, the decomposition apparatus 100 includes a control unit (not shown) that integrally controls the operation of the decomposition apparatus 100. The control unit can be realized by, for example, a computer having an arithmetic device or the like.

  FIG. 3 is a diagram illustrating an example of a hardware configuration of the computer 110 that realizes the function of the control unit. The computer 110 includes an arithmetic device 141, a memory 142, an external storage device 143, an output I / F (Interface) 144, an input I / F 145, and a storage medium driving device 146. It is connected. In addition, a timer 147 is connected to the input I / F 145.

  The arithmetic device 141 is a central arithmetic device such as a CPU (Central Processing Unit), and executes processing according to a program recorded in the memory 142 or the external storage device 143. Each processing unit constituting the computer 110 realizes each function by the arithmetic device 141 executing a program.

  The memory 142 is a storage device such as a RAM (Random Access Memory) or a flash memory, and functions as a storage area from which programs and data are temporarily read. The external storage device 143 is a writable and readable storage medium such as an HDD (Hard Disk Drive).

  The output I / F 144 is an interface for outputting information to each connected device. The input I / F 145 is an interface for receiving signal input from each connected device. The storage medium driving device 146 is a device that inputs and outputs information from a portable recording medium 148 such as a CD (Compact Disk) or a DVD (Digital Versatile Disk). The timer 147 is a measuring instrument that measures the heating time for the terminal device 200.

  FIG. 4 is a flowchart illustrating an example of a terminal device disassembling method according to the first embodiment. The process of this figure is started when the disassembly apparatus 100 is activated by turning on the power, for example.

  First, the heating unit 10 with a holding function starts heating (step S11). For example, when the decomposition apparatus 100 receives a start instruction via the input I / F 145, the heating unit 10 with a holding function starts heating under the control of the control unit.

  Next, the terminal device 200 to be disassembled is placed on the component supply / removal unit BU (step S12). The terminal device 200 is placed on the component supply / removal unit BU so that the end of the terminal device 200 with the front plate 1 facing downward contacts the alignment member 31. Accordingly, the terminal device 200 is repeatedly placed on the heating / separation unit KU at the same position and posture. The control unit may transport the terminal device 200 to be disassembled using a separately prepared transport device such as a robot or a conveyor, and place it on the component supply / removal unit BU.

  Next, the control unit causes the case holding unit 11 to attract the case 2 of the terminal device 200 (step S13). Specifically, the movable unit 12 having the housing holding unit 11 has the end of the housing slide unit 33 as the initial position in the x direction, and lowers the housing holding unit 11 (moves in the −z direction). It is comprised so that the terminal device 200 may be adsorbed. The control unit detects that the housing holding unit 11 is in contact with the housing 2 by the lowering of the housing holding unit 11 by the movable unit 12, and causes the housing holding unit 11 to start sucking the housing 2. .

  Next, the movable part 12 moves the housing holding part 11 (step S14). The control unit controls the movable unit 12 to perform the following operation. First, the movable unit 12 moves the housing holding unit 11 that has attracted the terminal device 200 upward. Next, the movable portion 12 moves the housing holding portion 11 along the housing slide unit 33 from the component supply / removal unit BU to above the heating / separation unit KU. Next, the movable unit 12 moves the housing holding unit 11 downward and places the terminal device 200 on the heating / separation unit KU.

  FIG. 5 is a diagram (part 1) for explaining a terminal device disassembling method. FIG. 5A is a top view of the disassembling apparatus 100, and FIG. 5B is a front view of the disassembling apparatus 100. When the case holding unit 11 sucks the case 2 of the terminal device 200, the movable unit 12 raises the case holding unit 11 ((1) in the figure), and the movable unit 12 is moved along the case slide unit 33. Moves above the heating / separation unit KU ((2) in the figure).

  FIG. 6 is a diagram (No. 2) for explaining the terminal device disassembling method. 6A is a top view of the disassembling apparatus 100, and FIG. 6B is a front view of the disassembling apparatus 100. FIG. After the movable part 12 is moved above the heating / separation unit KU ((2) in the figure), the movable part 12 lowers the housing holding part 11 and places the terminal device 200 on the heating part 10 with a holding function. ((3) in the figure). Since heating of the heating unit 10 with a holding function has already been started in step S11 described above, heating of the terminal device 200 is started by placing the terminal device 200 on the heating unit 10 with a holding function ((in the drawing ( 4)). At this time, as the temperature of the front plate 1 increases, the tensile shear strength of the adhesive layer 4 decreases.

  Returning to FIG. Next, the heating unit 10 with a holding function sucks the front plate 1 (step S15).

  Next, a control part detects adsorption | suction of the front plate 1 by the heating part 10 with a holding function with a sensor etc., and makes a timer start the measurement of heating time (step S16). A heating time suitable for disassembling the terminal device 200 is set in advance in the timer.

  When the preset heating time has elapsed, the timer ends the measurement (step S17). The control unit may output the progress of the heating time to an output device separately prepared via the output I / F 144.

  Next, a control part stops heating with respect to the heating part 10 with a holding function (step S18). In this embodiment, from the viewpoint of work safety and battery protection, heating is stopped before performing the separation operation, but it is not essential to stop the heating.

  Next, the control unit causes the movable unit 12 to perform a separation operation. In the present embodiment, as the separation operation, the housing holder 11 is moved upward (step S19). At this point, the tensile shear strength of the adhesive layer 4 is reduced by heating. If the casing 2 adsorbed by the casing holding unit 11 is moved upward while the heating unit 10 with the holding function is adsorbing the front plate 1, the casing 2 is moved from the front plate 1 to the casing 2. A peeling force is applied in a direction away (+ z direction), and the adhesive force of the adhesive layer 4 is reduced. If the adhesive force is small, it can be separated only by this treatment. In that case, the next step 20 may be skipped.

  Next, the control unit moves the scraper 13 from the scraper unit SU in the direction of the heating / separation unit KU (−x direction), and divides the adhesive layer 4 (step S20). Specifically, the scraper slide unit 32 on which the scraper 13 is installed moves in the direction of the heating / separation unit KU by driving of the drive device of the scraper unit SU. Thereby, the scraper 13 is inserted into the adhesive layer 4, and the adhesive layer 4 itself is divided by the pressure applied to the adhesive layer 4, or the adhesive surface of the adhesive layer 4 between at least one of the front plate 1 and the housing 2 and the adhesive layer 4. The adhesive force is further weakened, and the front plate 1 and the housing 2 are divided at the adhesive surface. These processes in step 19 and step 20 may be performed only in one or both in parallel or in reverse order.

  Next, the control unit moves the housing holding unit 11 toward the component supply / removal unit BU with respect to the movable unit 12 (step S21). The movable unit 12 raises the housing holding unit 11 that has attracted the housing 2 as necessary, and slides the housing holding unit 11 along the housing slide unit 33.

  FIG. 7 is a diagram (No. 3) for explaining the terminal device disassembling method. After stopping the heating of the heating unit 10 with the holding function, the housing holding unit 11 is raised by the movable unit 12 ((5) in the figure), and the adhesive layer 4 is divided by the movement of the scraper 13 ((6 in the figure) )). The housing holder 11 is raised as necessary ((7) in the figure), and the movable body 12 moves the housing holder 11 to the component supply / removal / peel unit BU ((8) in the figure). .

  Returning to FIG. Next, the control unit stops the housing 2 from sucking the housing 2 (step S22).

  Next, the control unit accommodates the housing 2 in the collection container using a separately prepared transport device (step S23).

  Next, a control part stops adsorption | suction of the front plate 1 with respect to the heating part 10 with a holding function (step S24). Thereby, the front plate 1 can be recovered from the heating unit 10 with a holding function.

  Next, the control unit accommodates the front plate 1 in the collection container using a separately prepared transport device (step S25). In addition, since the suction force may be reduced by closing the suction hole 9 of the housing holding portion 11 with a broken piece of the adhesive layer 4, in this embodiment, the housing holding portion is used for transporting the front plate 1 to the collection container. 11 is not used, but the front plate 1 may be accommodated in the collection container using the housing holding part 11.

  After step S25, the process of this flowchart ends.

  In the above embodiment, the movable part 12 applies a force to peel the casing 2 away from the front plate 1 (+ z direction) by moving the housing holding part 11 upward (+ z direction). The adhesive strength of the adhesive layer 4 is weakened. If it is possible to weaken the adhesive force of the adhesive layer 4, any direction, that is, the housing holding part 11 is ± x direction (left and right direction), ± y direction (depth direction), ± z direction (vertical direction) ), Or may be pressurized by moving in a direction in which two or more are combined.

(Modification)
FIG. 8 is a diagram illustrating a configuration example of the disassembling apparatus 100 according to the first modification of the first embodiment. The decomposition apparatus 100 in this modification has a movable part 12b that moves the heating part 10 with a holding function in addition to the movable part 12a that moves the housing holding part 11. Similar to the movable unit 12 in the above-described embodiment, the movable unit 12a conveys the housing 2 by moving the housing holding unit 11 along the housing-side slide unit 33 or moving up and down. The movable part 12b is installed on the front plate side base 40 and moves the heating part 10 with a holding function by moving up and down.

  FIG. 9 is a diagram for explaining the flow of disassembly in the first modification of the first embodiment. FIG. 9 shows a predetermined portion including the tip of the scraper 13 for the sake of convenience, and the other portions are not shown.

  First, similarly to the above-described embodiment, the terminal device 200 is installed in the decomposition apparatus 100, and the heating unit 10 with a holding function heats the front plate 1. Under the control of the control unit, the movable unit 12b moves the heating unit 10 with a holding function that holds the front plate 1 in a direction opposite to the case holding unit 11 (−z direction). Similarly, the movable part 12a moves the case holding part 11 holding the case 2 in the direction opposite to the direction toward the heating part 10 with a holding function (+ z direction). That is, the movable part 12a and the movable part 12b apply a force so as to move the heating part 10 with the holding function and the casing holding part 11 away from each other. Thereby, it becomes easy to insert the scraper 13 between the front plate 1 and the housing 2.

  FIG. 9A is a diagram illustrating a state in which the scraper 13 is moved to the vicinity of the center of the terminal device 200. The scraper 13 is inserted between the front plate 1 and the housing 2 from one end of the adhesive layer 4, moves along the adhesive surface (−x direction), and reaches the other end. Thereby, the front plate 1 and the housing | casing 2 are isolate | separated (FIG. 9 (B)).

  As can be seen from the first embodiment and its modification, the adhesive layer 4 can be bonded by relatively moving the heating unit 10 with a holding function and the housing holding unit 11 (at least one of them is moved). A force that weakens the force works, and the front plate 1 and the housing 2 can be easily separated. Moreover, since it becomes easy to isolate | separate by weakening the adhesive force of the contact bonding layer 4 by heating, a decomposition | disassembly operation | work can be performed efficiently.

(Second Embodiment)
Next, a second embodiment will be described. Hereinafter, differences from the above-described embodiment will be described. FIG. 10 is a diagram illustrating a configuration example of the disassembling apparatus 100 according to the second embodiment. The decomposition apparatus 100 in the second embodiment measures the heating temperature for the terminal apparatus 200 and separates the front plate 1 and the housing 2 at an appropriate timing. Hereinafter, a description will be given focusing on differences from the above-described embodiment.

  The decomposition apparatus 100 has a radiation thermometer 14. The radiation thermometer 14 is a thermometer that can measure the temperature without contacting the object, and is used for measuring the surface temperature of the housing 2. Instead of the radiation thermometer 14, a thermometer that measures the temperature by contacting the housing 2 may be used.

  As the battery 5 built in the terminal device 200, a small and high-performance lithium ion battery is often used. Since the lithium ion battery may ignite at a high temperature, the temperature of the battery 5 is managed using the radiation thermometer 14, and the adhesive layer 4 is at a set temperature at which the enclosure temperature in the vicinity of the battery is equal to or lower than the battery protection temperature. Is heated for a period of time when the tensile shear strength of the steel sheet is reduced by a predetermined amount.

  FIG. 11 is a diagram showing an outline of the estimation of the temperature of the battery 5. Since the battery 5 is built in the terminal device 200 as shown in FIG. 1, the temperature cannot be measured directly. Therefore, the temperature of the built-in battery 5 is estimated based on the temperature measured from the outside of the terminal device 200. In order to estimate the temperature of the battery 5, the internal and external temperatures of the terminal device 200 are measured using the disassembled terminal device 200, and a profile is created.

  FIG. 11B is a diagram illustrating a temperature measurement location of the terminal device 200 for creating a profile. The profile shown in FIG. 11A shows the result of measuring the temperature in “a”, “b”, “c”, “d”, “e”, “f”, and “g” in FIG. It is. The profile shown in FIG. 11A is a record of the progress of heating the front plate 1 at about 160 ° C. by placing the terminal device 200 using aluminum in the housing 2 on the heating unit 10 with a holding function. .

  From the profile, the relationship between “g” that is the temperature of the battery 5 and “e” and “f” that are the temperatures of the housing 2 that can be measured from the outside can be understood. From this relationship, the temperature of “e” or “f” when “g” in the profile is the protection temperature of the battery 5 is specified in advance.

  When the decomposition apparatus 100 performs decomposition, the radiation thermometer 14 measures the temperature corresponding to “e” or “f” while the heating unit 10 with a holding function performs heating, and the protection temperature of the battery 5 The controller controls the temperature so as not to exceed the value. Thereafter, the front plate 1 and the housing 2 are separated from each other as in the previous embodiments. It should be noted that other locations may be used as long as the correlation can be obtained with the temperature “g” of the battery 5.

  FIG. 12 is a block diagram illustrating additional functions of the control unit 120 according to the second embodiment. The control unit 120 includes a temperature acquisition unit 121, a determination unit 122, and a storage unit 130 in addition to the above-described function that controls the operation of the decomposition apparatus 100 in an integrated manner. The storage unit 130 stores heating condition information 131.

  The temperature acquisition unit 121 acquires the temperature outside the housing 2 of the terminal device 200 using the radiation thermometer 14. The determination unit 122 determines whether the temperature outside the housing 2 satisfies a condition stored in heating condition information 131 described later.

  The heating condition information 131 stores conditions for managing heating. The conditions for controlling the heating are, for example, the temperature range outside the housing 2 where the temperature of the battery 5 does not exceed the protection temperature and can weaken the adhesive force of the adhesive layer 4, and the duration of the temperature range, It is created based on the aforementioned profile. Of course, the heating condition information 131 is not limited to the temperature range and the duration of the temperature range.

  FIG. 13 is a flowchart illustrating an example of a method for disassembling the terminal device 200 according to the second embodiment. Similar to the disassembling method of the terminal device 200 in the first embodiment shown in FIG. 4, this processing is started when the disassembling device 100 is activated by turning on the power, for example.

  First, the heating unit 10 with a holding function starts heating (step S31). Since the process performed from step S31 to step S35 is the same as the process performed from the above-mentioned step S11 to step S15, description is abbreviate | omitted.

  Next, the temperature acquisition unit 121 acquires the temperature outside the housing (step S36).

  Next, the determination unit 122 determines whether or not the temperature in the temperature range of the heating condition has continued for a predetermined time (step S37). Specifically, when the determination unit 122 determines that the temperature of the casing acquired by the temperature acquisition unit 121 in step S26 has reached the temperature range stored in the heating condition information 131, the determination unit 122 uses the timer to continue the duration. Measure. The determination unit 122 determines whether the temperature within the temperature range has continued for the duration stored in the heating condition information 131.

  When the determination unit 122 does not determine that the temperature in the temperature range has continued for a predetermined time (in the case of “NO” in step S37), the determination unit 122 repeats the process of step S37.

  When the determination unit 122 determines that the temperature in the temperature range has continued for a predetermined time (in the case of “YES” in step S37), the temperature acquisition unit 121 stops acquiring the temperature of the housing (step S38).

  Next, the heating unit 10 with a holding function stops heating under the control of the control unit (step S39). Since the process performed from step S39 to step S46 is the same as the process performed from step S18 to step S25, description is abbreviate | omitted.

  According to the present embodiment, it is possible to reduce the risk associated with the temperature rise of the battery 5 when the terminal device 200 is disassembled.

(Modification)
Next, a modification of the second embodiment will be described. Since the position, material, and the like of the battery 5 are different for each model of the terminal device 200, in this embodiment, the heating condition information is provided for each model of the terminal device 200, and heating is performed under the heating condition according to the model.

  FIG. 14 is a block diagram illustrating additional functions of the control unit 120 according to a modification of the second embodiment. The control unit 120 includes a terminal model specifying unit 123 in addition to the temperature acquisition unit 121, the determination unit 122, and the storage unit 130. The storage unit 130 includes model-specific heating condition information 132 and terminal model information 133 instead of the heating condition information 131.

  The terminal model specifying unit 123 acquires the feature information of the terminal device 200 using the feature information acquisition device provided in the component supply / removal unit BU. The terminal model specifying unit 123 specifies the model of the terminal device 200 by referring to the terminal model information 133 using the acquired feature information. The feature information acquisition device is, for example, an optical sensor or a weight sensor, and acquires, for example, the outer dimensions and weight of the terminal device 200 as the feature information. The feature information acquisition device is, for example, a camera, and acquires, for example, an image of the terminal device 200 as feature information.

  The model-specific heating condition information 132 is information in which a heating condition used for determining whether to stop heating of the terminal device 200 is associated with each model of the terminal device 200. The terminal model information 133 is information in which feature information is stored for each model of the terminal device 200.

  After the control unit 120 places the terminal device 200 on the component supply / removal unit BU in the above-described step S32, the terminal model specifying unit 123 uses the feature information acquired by the feature information acquisition device to use the terminal model. With reference to the information 133, the model associated with the acquired feature information is specified.

  In step S38 described above, the determination unit 122 identifies the heating condition associated with the model identified by the terminal model identification unit 123. The determination unit 122 determines whether or not the specified heating condition is satisfied using information acquired from the temperature acquisition unit 121 and the timer.

  According to the present embodiment, even when terminal devices 200 of different models are continuously disassembled, automatic disassembly can be efficiently performed according to each model.

(Third embodiment)
Next, a third embodiment will be described. Hereinafter, a description will be given focusing on differences from the above-described embodiment. The decomposition apparatus 100 in the present embodiment does not have the heating unit 10 with a holding function, but instead has a front plate center holding unit that sucks the center of the front plate 1 and a heating unit 15 that heats the peripheral portion of the front plate 1. And have.

  FIG. 15 is a diagram illustrating a configuration example of the disassembling apparatus 100 according to the third embodiment. FIG. 15A is a top view of the disassembling apparatus 100 in the third embodiment, and FIG. 15B is a front view of the disassembling apparatus 100 in the third embodiment. The decomposition apparatus 100 in this embodiment includes a heating unit 15 and a front plate center holding unit 16 instead of the heating unit 10 with a holding function.

  The front plate center holding portion 16 has one or a plurality of holes 9 and sucks air from the holes 9 to adsorb the center portion of the front plate 1. The front plate 1 is fixed to the decomposition apparatus 100 by suction of the front plate center holding portion 16. The adsorption method is not limited to the method using negative pressure, as in the previous embodiments.

  The heating unit 15 is provided around the front plate center holding unit 16. In the disassembling apparatus 100 shown in FIG. 15, the heating unit 15 is formed over the entire periphery of the front plate center holding unit 16, and the peripheral portion including the four sides of the terminal device 200 is heated. Since the terminal device 200 often has the peripheral portion of the front plate 1 bonded to the housing 2, the peripheral portion including the four sides of the terminal device 200 is used to reduce the tensile shear strength of the adhesive material. It is enough to heat. Therefore, in this embodiment, the peripheral part of the terminal device 200 is heated by the heating part 15. Since the battery 5 is often installed near the center of the terminal device 200, this configuration can prevent an unintended temperature rise of the battery 5.

  The decomposition apparatus 100 in the present embodiment improves the ease of inserting the scraper by heating the peripheral edge of the terminal device 200. However, it is easy to insert the scraper by heating only the portion close to the scraper in the peripheral portion, and even if heating is performed along the insertion direction (−x direction) of the scraper, the separation of the adhesive layer is propagated. Therefore, only a part of the peripheral edge of the front plate 1 may be heated. These will be described in detail in other embodiments.

(Fourth embodiment)
Next, a fourth embodiment will be described. Hereinafter, differences from the above-described embodiment will be described. Similarly to the third embodiment, the heating unit 15 in the present embodiment is provided at a position where the periphery of the front plate center holding unit 16 is heated, and heats the peripheral portion of the front plate 1 excluding the central portion. The center part of the front plate 1 is adsorbed by the front plate cooling holding unit, and the casing 2 is adsorbed by the casing cooling holding unit. The front plate cooling holder and the casing cooling holder have a cooling function.

In addition to the heating unit 15, the decomposition apparatus 100 in the present embodiment includes a front plate cooling holding unit 17 and a casing cooling holding unit 18. The decomposition apparatus 100 may have a scraper 13. The front plate cooling and holding unit 17 has one or a plurality of holes 9, and adsorbs the central portion of the front plate 1 using negative pressure, and does not adsorb at least a part of the peripheral portion. In this respect, the front plate cooling holder 17 functions as a front plate holder. The heating unit 15 heats the peripheral portion of the front plate 1 that has not been adsorbed by the front plate cooling and holding unit 17. In addition, although the heating part 15 has the hole 9 which adsorb | sucks the front plate 1, the adsorption | suction function is not provided in this embodiment.

  Similarly, the housing cooling and holding unit 18 has one or a plurality of holes 9 and sucks and holds the housing 2 by sucking air from the holes 9. In this respect, the case cooling holding unit 18 functions as a case holding unit.

  The front plate cooling holder 17 has a coolant flow path 19. The coolant flow path 19 is a tube through which coolant (refrigerant such as water) flowing out from a separately prepared pump flows. The coolant flowing through the coolant channel 19 may be adjusted to a predetermined temperature by a separately prepared liquid temperature management device connected to the pump. By flowing the coolant through the coolant channel 19, the central portion of the front plate 1 of the terminal device 200 heated by the heating unit 15 is cooled. In this respect, the front plate cooling and holding unit 17 functions as a front plate cooling unit. The cooling of the front plate 1 by the front plate cooling holding unit 17 is performed in parallel with the heating of the peripheral portion of the front plate 1 by the heating unit 15 or continuously after the heating is stopped.

  Similarly to the front plate cooling holding unit 17, the case cooling holding unit 18 also has a coolant flow path 20 and cools the case 2 of the terminal device 200 heated by the heating unit 15. Thereby, the heating risk of the battery 5 can be reduced.

  In addition, this embodiment cools the center part of the front plate 1 by the front plate cooling and holding unit 17 and cools the case 2 by the case cooling and holding unit 18 so that the two opposing surfaces of the terminal device 200 are provided. Although it cools simultaneously, the housing | casing cooling holding | maintenance part 18 may not have a cooling function similarly to the housing | casing holding | maintenance part 11 of Embodiment 1. FIG. By heating the peripheral portion of the front plate 1 with the heating unit 15 and cooling the central portion with the front plate cooling and holding unit 17, the heating and cooling temperatures are adjusted so that the terminal device 200 can be disassembled efficiently. The front plate 1 and the housing 2 can be separated.

  FIG. 17 is a diagram illustrating an example of the structure of the front plate cooling holder 17 according to the fourth embodiment. FIG. 17A is a top cross-sectional view of the front plate cooling and holding unit 17, and FIG. 17B is a front cross-sectional view of the front plate cooling and holding unit 17 taken along the line CD.

  The coolant flow path 19 is installed in a bent shape so that the front plate 1 can be efficiently cooled. Further, as shown in FIG. 17B, the coolant flow path 19 is configured to allow the coolant to flow in from the lower surface and flow out from the lower surface when the surface on which the front plate 1 is installed is installed on the upper side. . In FIG. 17, the flow of the coolant and air is illustrated using arrows.

(Modification)
Next, a modification of the fourth embodiment will be described. In this modification, the center part of the front plate 1 is cooled by flowing air through the pipe instead of the coolant.

  FIG. 18 is a cross-sectional view focusing on the heating / separation unit KU and the housing holding part 11 in the disassembling apparatus 100 according to the modification of the fourth embodiment. The front plate cooling holder 17 and the case cooling holder 18 in this modification have a cavity 21 instead of the coolant channel 19. The cavity 21 is open on the side in contact with the terminal device 200, and the terminal device 200 is cooled by air flowing in or out of the air flow path 22 provided on the side opposite to the surface in contact with the terminal device 200. The air flow path 22 is connected to a separately prepared compressor or the like, and air that has been adjusted to room temperature or a constant temperature flows in. In FIG. 18, the flow of air is illustrated using arrows. 18 shows the case cooling holding part 18 having the cavity 21, the case cooling holding part 18 may not have a cooling function.

(Fifth embodiment)
Next, a fifth embodiment will be described. Hereinafter, a description will be given focusing on differences from the fourth embodiment. In the present embodiment, when the heating unit 15 heats the front plate 1, not all are heated at the same temperature, but the temperature is partially changed.

  FIG. 19 is a diagram focusing on the heating / separation unit KU and the housing holding part 11 in the disassembling apparatus 100 according to the modification of the fifth embodiment. FIG. 19A shows a front cross-sectional view of the heating / separation unit KU and the housing holding part 11 in the present embodiment, and FIG. 19B shows the first of the decomposition apparatus 100 in the present embodiment. 4 is a top cross-sectional view of a separation heating unit 23 and a second separation heating unit 24. FIG. The decomposition apparatus 100 in this embodiment includes a front plate cooling and holding unit 17, a casing cooling and holding unit 18, a scraper 13, a first separation heating unit 23, and a second separation heating unit 24. . The front plate cooling holder 17 and the case cooling holder 18 do not necessarily have a cooling function.

  The first separation heating unit 23 is a first region (of the front plate 1 of the front plate 1) in the periphery of the front plate cooling and holding unit 17 (including the outer edge portion of the terminal device 200). (A region including one side near the scraper 13 on the outer edge).

  The second separation heating unit 24 is provided in a second region other than the first region around the front plate cooling holding unit 17.

  The first separation heating unit 23 heats the first region. The second separation heating unit 24 heats the second region. The first separation heating unit 23 heats the first region to a temperature higher than that of the second region by heating at a temperature higher than that of the second separation heating unit 24. For example, the temperature of the heating source of the first separation heating unit 23 is set to 250 ° C., and the temperature of the heating source of the second separation heating unit 24 is set to 150 ° C. Heat. Due to the heating of the first separation heating unit 23, the tensile shear strength of the adhesive layer 4 close to the first region is lowered faster than the adhesive layer 4 close to the second region. Therefore, the scraper 13 can be inserted quickly and easily.

  The movable part 12 pulls the front plate 1 in the range heated by the first separation heating part 23 by moving the housing cooling holding part 18, and then the scraper 13 is inserted into the adhesive layer 4 from the first region. Move to the other end. Thereby, the front plate 1 and the housing | casing 2 isolate | separate.

  In FIG. 19, the first separation heating unit 23 and the second separation heating unit 24 are physically divided, but the heating unit does not need to be physically separated, and is classified by region. Any device capable of setting the temperature may be used.

  According to the present embodiment, the terminal device 200 can be disassembled without heating the entire front plate 1 to a high temperature. Thereby, the cost used for heating can be reduced, and the risk due to the temperature rise of the battery 5 can be reduced.
