Description

  The present invention relates to a processing method and apparatus for a portable device.

  There are many portable devices around us today. The “portable device” in this specification refers to a device that can be carried and used. The portable device includes a communication device (terminal) and an information device (terminal). Various communication devices such as a multi-function mobile phone called a smartphone and a mobile Wi-Fi router are known, and various information devices such as a tablet and an electronic book terminal are known.

  Currently, from the viewpoint of securing resources, it is required to collect parts that constitute a used mobile device from the mobile device. And as the said component, the secondary battery used as the motive power source of the said portable apparatus is mentioned, for example. As the secondary battery, for example, a lithium ion battery is widely used in portable devices. The lithium ion battery is also referred to as a lithium ion secondary battery, hereinafter simply referred to as “LIB”, and LIB is given as a representative example of the secondary battery.

  Portable devices are miniaturized to facilitate carrying and use. On the other hand, the performance of the mobile device is increasing, and the power required by the mobile device is also increasing. Under such circumstances, the LIB is frequently used in the portable device because it can supply relatively high power compared to its size.

  For example, assuming a case where LIB is collected from a portable device, conventionally, the operation of collecting LIB from the portable device has to be performed manually. As long as it is done manually, the cost will naturally increase.

  In addition, there are many tablet terminals that incorporate a secondary battery (for example, LIB) among portable devices. As used herein, “tablet terminal” refers to a terminal that is a plate-like electronic device. Many tablet terminals have a touch panel display. The “touch panel display” refers to a display in which a display for displaying a screen and a touch panel are integrated. When a touch panel display is employed, considerable downsizing (thinning) can be realized, and a thin portable device can be provided. However, on the other hand, as long as it is thin, it is necessary to reduce the thickness of the LIB, and it is formed by inserting a plate-shaped (square) LIB, or in some cases, an electrolyte and an electrode into a resin film. It becomes necessary to attach a laminate-type LIB (also referred to as a battery pack) to a thin portable device. In this case, there is a high possibility that the LIB main body or the battery pack will be accidentally damaged when collecting the LIB from the portable device. That is, precision is required for the operation of collecting LIB from the portable device, and a highly skilled worker is required. If it becomes so, it will become difficult to shorten working time and the processing expense of a portable apparatus will increase further.

As means for solving the above problems, the present inventor is examining whether or not the technique disclosed by the present applicant (Japanese Patent Laid-Open No. 2014-183617) can be used based on his own knowledge. This technique is a technique for recovering a rare earth magnet disposed in a rotor, and is a technique in which a mild impact is applied to the rotor from the outside to discharge the inner rare earth magnet to the outside of the rotor.
However, when this technique was applied to the above case, the LIB was separated from the portable device, but the LIB was severely crushed, and the LIB could not be recovered satisfactorily.

  The present invention proposes a technique for efficiently recovering a secondary battery while collecting the secondary battery from a used portable device, without relying only on manual work and suppressing the secondary battery from being crushed. It is an object to do.

  In order to solve the above problems, the present inventor has intensively studied. At that time, the present inventor paid attention to the installation status of the LIB inside the portable device. As a result, the present inventor has obtained the knowledge that LIB is not firmly fixed inside the mobile device, but is fixed to the extent that it is fixed inside the mobile device with an adhesive in some cases. On the other hand, when the technique disclosed by the present applicant is applied to this case, it has also been found that the LIB is crushed because the impact is excessively applied to the portable device many times. Based on these findings, the present inventor has obtained the knowledge that the method of “applying a moderate impact at a time” is effective for a portable device when processing to collect LIB from the portable device is performed. .

In the present embodiment, the description will be made assuming that the top direction is the top direction and the ground direction is the bottom direction.

<1. Processing device 1 of portable device α>
First, the processing apparatus of the portable device α in the present embodiment is for separating LIB from the portable device α. A basic configuration of the processing apparatus will be described with reference to FIG. FIG. 1 is a diagram showing an outline of the processing device 1 of the portable device α in the present embodiment.
The processing apparatus 1 of the portable device α in the present embodiment has the following configuration.
・ Processing chamber 2 for processing used mobile devices α
A loading unit 3 for loading the mobile device α into the processing chamber 2
A rotating body 4 that is arranged in the processing chamber 2 and that blows the portable device α that is input from the input unit 3.
A scattering part 5 for scattering the position where the portable device α collides with the rotating body
-Collision part 6 which becomes the colliding destination of portable device α blown off by rotating body 4
Hereinafter, each configuration will be described in detail.

1-A) Processing chamber 2
The processing chamber 2 in the present embodiment refers to a portion for processing the used mobile device α. A rotating body 4 and a collision unit 6 are provided in the processing chamber 2. As a specific structure, the configuration of the processing chamber 2 used for processing the used portable device α in a known apparatus may be adopted.

1-B) Input part 3
The input unit 3 in the present embodiment is a part for supplying the used portable device α into the processing chamber 2 and may be called a supply unit. As a specific structure, in a known apparatus, a configuration provided for supplying the used portable device α into the processing chamber 2 may be adopted. In the present embodiment, as shown in FIG. 1, an example in which an input port provided with an inclination that allows the portable device α to slide down into the processing chamber 2 is used as the input unit 3 will be described. Of course, a configuration may be provided in which the portable device α is thrown into the processing chamber 2 by a conveyor or the like, or the portable device α is thrown into the processing chamber 2 by being dropped.

  Note that the insertion unit 3 in the present embodiment is directed to the portable device α toward the starting point side in the rotation direction of the rotating body 4 (hereinafter also simply referred to as “upstream side”) in the upper half of the rotating body 4. Is placed in a position where it can be inserted. When the portable device α is thrown into the processing chamber 2 from the throwing portion 3, the portable device α slides down on the rotating rotating body 4 and is caught by the protruding portion 42. And the portable apparatus (alpha) remove | deviates from the protrusion part 42 with the peripheral speed of the rotary body 4, and is skipped to the collision part 6. FIG. By this operation, it is possible to apply an appropriate impact to the portable device α at a time. Note that the flying of the portable device α to the collision unit 6 is also referred to as “giving acceleration to the portable device α”.

  As described above as the knowledge of the present invention, the LIB is not firmly fixed in the portable device α that is a tablet terminal including a secondary battery (for example, LIB) and includes a touch panel display. Therefore, it is better that the impact given to the portable device α is not too large so as not to destroy other parts. On the other hand, if the technology disclosed by the present applicant is applied in this case, if the impact is excessively applied to the mobile device α many times, the LIB itself is crushed to cause electric leakage or ignition. It can be. In order to solve this situation, in the present embodiment, the mobile device α is applied to the mobile device α at a time by causing the mobile device α to fly and collide with the collision unit 6 by the rotating body 4. Adopted.

  In the present specification, “LIB crushing (and thus secondary battery crushing)” refers to a situation in which sparks due to ignition, short circuit, and electrolyte leakage occur as the LIB is damaged. In other words, “suppressing LIB crushing” means preventing the above-mentioned phenomena from occurring, and as long as this state can be maintained, the LIB casing (exterior) There is no limitation on the amount of deformation.

  If the LIB is separated by the flying device 4 thrown by the throwing unit 3 and the collision with the collision unit 6, the LIB falls downward from a gap (W, etc.) described later. LIB is stored in the storage section.

  On the other hand, even if the LIB is not separated from the portable device α due to flying and collision, the portable device α falls downward with the LIB built-in, and the portable device α is stored in a storage unit described later. Therefore, after the selection, the portable device α may be input again from the input unit 3 onto the rotating body 4.

As described above as the knowledge of the present invention, if the impact is excessively applied to the portable device α many times, the LIB is crushed. Therefore, a method of “applying a moderate impact at a time” to the portable device α is effective. In other words, it is ideal that the chance of collision of the mobile device α is once. In order to bring this ideal closer to reality, the configuration described in this embodiment is employed. With the configuration of the present embodiment, it is possible to apply a moderate impact to most of the input portable devices α at a time.
Note that some portable devices α may return to the rotating body 4 again and be thrown back to the collision unit 6. However, the number of such portable devices α collides with the rotating body 4 in addition to a very small number. It can suppress by adjusting the distance with the part 6, and the peripheral speed of the rotary body 4. FIG.

  In the present specification, “the“ starting point side (ie, upstream side) ”in the rotation direction of the rotating body 4” refers to the portion from the leftmost to the uppermost portion in the rotating body 4 shown in FIG. However, it preferably refers to the vicinity of the leftmost portion of the rotating body 4.

  In the present embodiment, the portable device α is preferably supplied to the upstream side in the rotation direction of the rotating body 4. This is because the supply to the upstream side can make the collision with the collision part 6 vigorously.

  Further, in order to prevent the portable device α processed in the processing chamber 2 from flowing back from the input section 3 by mistake, a partition such as a chain curtain (not shown) is provided on the input section 3 in front of the processing chamber 2. It may be provided.

1-C) Rotating body 4
The rotating body 4 in the present embodiment is disposed in the processing chamber 2 and is used for skipping the portable device α input from the input unit 3. The rotating body 4 mainly has the following two configurations.
The rotor 41 that is the basis of the rotating body 4
A protruding portion 42 protruding from the peripheral surface of the rotor 41

1-Ca) Rotor 41
The rotor 41 in this embodiment has a roller shape that is a base of the rotating body 4. As a specific structure, in a known device, the configuration of the rotor 41 used for processing the used portable device α may be adopted. A shaft serving as a central axis of the rotor 41 is fixedly installed in the processing chamber 2.

1-Cb) Protruding portion 42
The protrusion 42 in the present embodiment is configured so that the portable device α input from the input unit 3 can be received when contacting the rotating body 4 and the portable device α can be skipped by the rotation of the rotating body 4. This refers to a portion protruding from the circumferential surface of the rotor 41. As a specific structure, in a known device, a device attached to a rotor 41 for processing a used portable device α (for example, a swing hammer described in JP-A-2004-267820) is adopted. It doesn't matter.

  In order to fly the mobile device α vigorously, it is preferable that the projecting portion 42 further has a configuration projecting in the rotation direction of the rotating body 4 as shown in FIG.

  Moreover, the number of the protrusion parts 42 may be arbitrary. However, in the rotating body 4 composed of a plurality of disks, it is preferable that 2 to 4 protrusions 42 are provided on each disk. By carrying out like this, the portable apparatus (alpha) can fully be skipped to the collision part 6, and crushing of LIB can also be suppressed.

  Further, the rotor 41 and the projecting portion 42 may be prepared as separate members and assembled to form the rotating body 4, or the rotor 41 and the projecting portion 42 may be integrally formed as the rotating body 4. .

  Further, in the present embodiment, the LIB separated from the portable device α by colliding with the collision unit 6 can be dropped without being caught between the rotating body 4 and the inner wall of the processing chamber 2. Is provided. This gap is provided so that at least a component (LIB or substrate) separated from the portable device α (in addition to the portable device α after colliding with the collision unit 6) does not collide with the collision unit 6 again by the rotating body 4. It can be appropriately adjusted according to the size and input amount of the portable device so that it can be collected.

The above gap can be adjusted as the distance between the end point side (downstream side) in the rotation direction of the rotating body 4 shown in FIG. 1, that is, the right side portion, the inner wall of the processing chamber 2 and the collision portion 6. By doing so, when a plurality of collision parts 6 (collision members 62) to be described later are provided, the gap between the collision member 62 located on the most end point side (downstream side) in the rotation direction and the rotating body 4 is passed. The LIB can be dropped below the rotating body 4 without the LIB being caught between the rotating body 4 and the inner wall of the processing chamber 2. That is, the LIB can be recovered with almost no LIB crushing.
Note that the gap may be provided at a place other than the above-described places. For example, a gap is provided between the rotating body 4 and the inner wall of the processing chamber 2 when viewed in the central axis direction of the rotating body 4. It doesn't matter. Therefore, the “gap” described in the present embodiment includes other than the gap shown in FIG. However, for convenience of explanation, a gap may be cited as a representative example of the gap.

1-D) Spatter part 5
In the present embodiment, the scattering unit 5 scatters the positions where the portable device α collides with the rotating body 4 when the plurality of portable devices α are input into the processing chamber 2 from the input unit 3. This part As described above, the present embodiment aims to “apply a moderate impact at a time” to separate LIB from the portable device α. On the other hand, when the portable device α is thrown into the open field from the throwing unit 3, it is expected that the portable device is thrown into a predetermined portion of the rotating body 4. In that case, after being blown off by the projecting portion 42, the mobile device α should collide with the collision unit 6 without contacting with the other portable device α. There is also a risk of taking the opportunity to give a moderate impact at a time. Therefore, in this embodiment, it becomes possible to suppress said fear by providing the scattering part 5. FIG.

  The configuration of the scattering unit 5 may be arbitrary as long as the position where the portable device α collides with the rotating body 4 can be scattered. If a specific configuration example is given, for example, an opening having a width that can be sufficiently passed to secure a space between the portable devices α between the insertion port in the insertion unit 3 and the front of the processing chamber 2. You may provide the grating | lattice provided with two or more. In addition, a flow of movement of the mobile device α in the input unit 3 from the input port in the input unit 3 to the front of the processing chamber 2 is used as a water divide when the mobile devices α move. In order to divide into a plurality, a protruding portion that protrudes perpendicular to the moving direction of the portable device α and perpendicular to the paper surface of FIG. 1 may be provided. Of course, the configuration as described above may be provided in front of the charging unit 3 or may be provided in the processing chamber 2 in some cases.

1-E) Colliding part 6
The collision unit 6 in the present embodiment is a part that becomes a collision destination of the portable device α that is blown off by the rotating body 4, and has a configuration capable of separating LIB from the portable device α due to an impact at the time of the collision. Refers to things.

The collision unit 6 has a collision surface that can realize the above-described content, has a hardness and a shape that can release the fixed state of the LIB built in the portable device α and can separate the LIB from the portable device α. If the said collision surface has, there will be no restriction | limiting in particular. If the specific example of the collision part 6 is given, the member 62 for a collision attached to the inner wall of the process chamber 2 and the connection member 61 provided with respect to the inner wall of the process chamber 2 will be mentioned. In the present embodiment, an example using the collision member 62 is given.
Less than,
The connecting member 61 provided for the inner wall of the processing chamber 2
A collision member 62 attached to the connecting member 61
Will be described.

1-Ea) connecting member 61
The connecting member 61 in the present embodiment has a function of connecting the processing chamber 2 and the collision member 62. As long as it has this function, a known member may be used.

By using the connecting member 61, the collision member 62 is provided at an arbitrary position away from the inner wall of the processing chamber 2. By doing so, first, it becomes possible to reduce damage and wear of the inner wall of the processing chamber 2.
Further, it is possible to employ a configuration in which the collision member 62 can be attached to and detached from the processing chamber 2. That is, even if the processing apparatus 1 of the present embodiment is used for a long period of time, if only the collision member 62 is replaced, it is possible to maintain a state where damage and wear are small.

  Of course, the connecting member 61 and the collision member 62 may be integrated as the collision portion 6, but a separate body is preferable because it can cope with a situation where only the collision member 62 needs to be replaced.

  Furthermore, when it is a separate body, it is possible to adopt a configuration that can adjust the angle of the collision member 62 with respect to the rotating body 4. By adopting this configuration, the angle of the collision surface of the collision member 62 with respect to the rotating body 4 can be adjusted according to the portable device α to be processed and the LIB to be collected.

  By adjusting the angle, the degree of impact applied to the portable device α can be adjusted. For example, when the trajectory on which the mobile device α is blown is defined as the tangential direction of the circumference of the rotating body 4, if the degree of impact is desired to be increased, the collision surface may be provided so as to face the tangential direction of the circumference. . On the other hand, when the mobile device α has only a relatively low strength, there is a possibility that the mobile device α and thus the LIB may be crushed by an impact caused by a collision. In that case, the angle of the collision member 62 may be changed so that the collision surface does not face the tangential direction of the circumference.

  Further, by changing the direction of the collision surface, after the portable device α collides with the collision surface, the portable device α after the collision can be quickly dropped from the gap or the like. In other words, the direction of the collision surface can be changed so that the number of collisions of the mobile device α is likely to be one.

1-Eb) Colliding member 62
The collision member 62 in the present embodiment is a portion having a collision surface that is a collision destination of the mobile device α that is blown by the rotating body 4. The collision member 62 has a function of separating the LIB from the portable device α by an impact at the time of the collision. As long as it has this function, a known member may be used.

  As a preferred form of the collision member 62, as described above in the section 1-Ea) the connecting member 61, the collision wall is provided away from the inner wall of the processing chamber 2, so that the inner wall of the processing chamber 2 is provided. This has the effect of suppressing damage and wear.

  As another preferred form of the collision member 62, as shown in FIG. 1, the collision surface has a curved shape that is dented toward the rotating body 4, and the rotating body 4 is on the extended line of the curved shape. There is a configuration that exists.

  First, since the collision surface has the curved shape as described above, the portable device α that is blown by the rotating body 4 falls on the curved surface smoothly after colliding with the collision surface. In a shape other than a curved shape, a plurality of portable devices α may stay on the collision surface while the portable device α is skipped from one to the next.

  As the shape of the collision surface, a plurality of protrusions may be provided on the curved surface in order to increase the degree of impact applied. The shape and material of the collision surface may be appropriately set according to the type of the mobile device α and the degree of impact to be applied.

  As another preferred form of the collision part 6, as shown in FIG. 1, a configuration in which a plurality of the collision parts 6 (that is, the collision members 62) are arranged in the rotation direction of the rotating body 4 can be mentioned. Of course, the number of collision members 62 is not limited to two, and may be three or more.

  By providing a plurality of collision members 62 aligned in the rotation direction, the following effects are obtained. Even if the portable device α does not collide with the first collision member 62 (upstream side) and passes through the gap between the first collision member 62 (upstream side) and the rotating body 4, the second It becomes possible to make it collide with the collision member 62 (downstream side).

  Further, in this case, it is preferable that the collision member 62 is arranged so that the ends of the collision portions 6 of the plurality of collision portions 6 overlap each other when viewed from the rotation center of the rotating body 4. In this way, the mobile device α can be reliably collided once.

  Moreover, it is preferable that the collision part 6 is distribute | arranged to the position where the clearance gap between each collision part 6 and the rotary body 4 becomes narrow as it progresses in a rotation direction among the plurality of collision parts 6 provided. Referring to FIG. 1, the gap between the second collision member 62 (downstream side) and the rotating body 4 is larger than the gap between the first collision member 62 (upstream side) and the rotating body 4. It is set narrowly. By carrying out like this, the possibility that the portable apparatus (alpha) after skipping may pass through all the collision parts 6 can be suppressed.

  In the above case, the collision part 6 includes the connecting member 61 and the collision member 62. Of course, other members may be provided as the collision part 6. In the first place, the collision part 6 may be used as the inner wall of the processing chamber 2. In that case, the above-listed examples can be applied even when the collision portion 6 is used as the inner wall of the processing chamber 2 by changing the shape of the inner wall of the processing chamber 2 to a shape preferable for the collision member 62 described above. It is. However, as described above, it is more advantageous to provide the collision member 62 separately from the inner wall of the processing chamber 2.

1-F) Storage Unit or Discharge Unit A storage unit for collecting the processed portable device α and the separated LIB is preferably provided below the rotating body 4 (not shown). By doing so, it is possible to suppress the portable device α from being caught between the rotating body 4 and the inner wall of the processing chamber 2. In addition, as the storage unit, for example, the portable device α is guided so that the portable device α after colliding with the collision unit 6 does not return onto the rotating body 4 (in other words, away from the rotating body 4). A guiding part may be formed, and the arrangement and shape of the connecting member 61 and the collision member 62 of the collision part 6 may be adjusted as appropriate.

  In addition to the above configuration, a configuration that is appropriately required for an apparatus for processing the used portable device α may be adopted.

<2. Processing method of portable device α>
Next, a processing method of the mobile device α in the present embodiment will be described. The contents of the following steps are <1. There is a part which overlaps with the contents explained in the section of processing device 1> of portable device α. Therefore, for contents not described below, <1. As described in the section of the processing apparatus 1> of the portable device α.

2-A) Input Process In the input process, the portable device α is input into the processing chamber 2. In addition, the processing method of the portable apparatus (alpha) in this embodiment can be performed continuously unlike the batch type. Therefore, the portable device α may be continuously input. In addition, the scattering unit 5 described above is installed inside the input unit 3, and the mobile device α collides with the rotating body 4 when a plurality of mobile devices α are input from the input unit 3 into the processing chamber 2. A scattering process for scattering the position to be performed may be performed. However, even if the scattering portion 5 is not provided, it is possible to perform LIB separation by performing the following steps and obtain the effects of the present invention.

  Incidentally, as will be described in the item of the embodiment described later, when a plurality of portable devices α are continuously input, there are cases where LIB cannot always be separated from all the portable devices α. However, when collecting LIB from a used portable device, there is no change in that LIB can be efficiently collected without depending on only manual work and suppressing LIB crushing. As a result, the present embodiment is sufficiently applicable even when a plurality of mobile devices α are continuously input, as a matter of course when the mobile device α is input alone.

2-B) Battery Separation Step In the battery separation step, the portable device α is blown by the rotation of the rotating body 4 arranged in the processing chamber 2 and caused to collide with the collision unit 6 in the battery separation step. Separate LIB from

  In the charging process, the portable device α is loaded toward the starting point side (that is, the upstream side) in the rotation direction of the rotating body 4 in the upper half of the rotating body 4. By doing so, the portable device α can be vigorously blown to the collision portion 6 and an appropriate impact can be given at one time.

  In addition, a sufficiently wide gap is provided between the rotating body 4 and the processing chamber 2. Therefore, the LIB separated from the portable device α by colliding with the collision unit 6 can be dropped without being caught between the rotating body 4 and the processing chamber 2.

  When LIB is collected from the portable device α, the rotational speed of the peripheral surface of the rotating body 4 (more specifically, the protruding portion 42, more specifically, the central portion of the protruding portion 42) is 7.5 m / s or more (the number of rotations) 15 Hz (1 / s) or more), and preferably 10 m / s or more (rotational speed 20 Hz (1 / s) or more). By doing so, it is possible to apply an appropriate impact to the mobile device α at a time. More specifically, when the speed is 7.5 m / s or more, the LIB can be reliably separated with the portable device α having an openable / closable lid that can replace the battery. When the speed is 10 m / s or more, the LIB can be reliably and efficiently separated even if the LIB-integrated portable device α has a structure in which the battery cannot be replaced by the end user of the portable device α. LIB can be reliably separated from various portable devices α.

  In addition, in order to make it hard to produce damage to LIB, it is preferable that the rotational speed of the surrounding surface of the rotary body 4 shall be 25 m / s or less (50 Hz or less). Furthermore, it is very preferable that the rotation speed of the peripheral surface of the rotating body 4 is 15 m / s or less (30 Hz or less). As shown in an example described later in which LIB is recovered from a used smartphone, under this condition, LIB can be recovered by the storage unit while naturally reducing the risk of breakage.

  In the present embodiment, the portable device α is processed by performing the above steps. However, in addition to the above steps, it is preferable to additionally perform the following steps.

2-C) Re-injection step In this step, the portable device α itself after the battery separation step or each of its components is collected by the storage unit, and then, what needs to be reintroduced is introduced into the processing chamber 2.

There are mainly two reasons for performing this step.
One is that, as described above, the LIB that has not been separated in one collision with the portable device α is thrown into the processing chamber 2 again (first recharging). Process). In this case, the same operation as the battery separation step described above may be performed after this step.

  Another reason other than the LIB separation re-challenge is separation of parts (for example, a substrate) other than LIB from the portable device α (second re-introduction step). There are also members formed of various valuable metals on the substrate mounted on the portable device α. Further, the gold quality of the portable device α after separating the LIB is often improved. Even if this is not the case, the substrate is often useful as a raw material for smelting. For this reason, collecting the substrate often contributes to improvement in economy. When performing this process for this reason, the following processes are performed.

2-D) Substrate Separation Step In this step, the substrate is separated from the portable device α by an impact when the recharged portable device α is blown by the rotation of the rotating body 4 and collides with the collision unit 6. Note that the first re-input step and the second re-input step may be performed together. However, it is preferable to perform both processes separately. More specifically, in the second recharging process, it is preferable to increase the rotational speed of the peripheral surface of the rotating body 4 than in the 2-B) battery separating process mentioned above. The reason is as follows.

  As described above, the LIB is not firmly fixed to the portable device α, but is fixed to the extent that it is fixed inside the portable device α by an adhesive in some cases. However, unlike the LIB, the substrate is often fixed to the portable device α by a locking member such as a screw. Therefore, the rotational speed of the peripheral surface of the rotator 4 is increased more than the battery separation step, the impact at the time of collision with the portable device α is increased, and the substrate is easily separated from the portable device α.

  After separating the substrate from the portable device α by the above method and collecting the substrate through the storage unit or the discharge unit, a sieving process, a magnetic separation process, or the like is appropriately performed. In addition, after recovering a predetermined part from the substrate, the substrate may be crushed and the material may be recovered for each material (for example, iron or copper) constituting the substrate. Thereafter, the elements may be recovered for each element by magnetic separation or XRF sorter.

<3. Advantages of the embodiment>
According to this embodiment, the following effects can be obtained.

  In the present embodiment, LIB separation can be ensured by adopting a configuration that aims to “apply a moderate impact at a time”. As a result, when collecting the LIB from the used portable device α, it is possible to provide a technique for collecting the LIB without depending on only manual work and suppressing LIB crushing.

  The LIB to be collected in the present embodiment (including later-described second embodiment; the same shall apply hereinafter) is not particularly limited as long as it is built in the portable device α including the touch panel display. As mentioned above, there are various cases such as mounting a rectangular LIB, and in some cases, a laminated LIB (battery pack) formed by inserting an electrolyte and an electrode into a resin film to a thin portable device α. In this case, the present embodiment can be applied.

  On the other hand, this embodiment has a remarkable effect when the lid for attaching / detaching the LIB is not separately provided in the exterior of the portable device α. The reason is as follows.

  First, the necessity of collecting the LIB built in the portable device α is as described above. When collecting the LIB, depending on the portable device α, a cover for attaching / detaching the LIB may be provided on the exterior. Even in this case, the present embodiment can be applied. However, as long as the lid is attached, the workability is improved. In such a case, the skill level is often not particularly necessary for the work, and the superiority of automation over the manual LIB separation is diminished.

  On the other hand, as the mobile device α is made thinner, the LIB has been made smaller and thinner. In that case, it cannot be denied that the durability of the LIB becomes weaker than before. In some cases, if the end user of the portable device α tries to replace the LIB, the possibility of damaging the LIB cannot be denied. As a countermeasure, there are many cases where a lid for attaching / detaching the LIB is not separately provided on the exterior of the portable device α.

  If this measure is adopted, the end user of the portable device α will certainly not be able to exchange the LIB. However, as in this case, it takes a lot of time to separate the LIB from the used portable device α.

  Depending on the mobile device α, a lid for attaching / detaching the LIB may not be separately provided on the exterior of the mobile device α, but the entire exterior may be a lid for attaching / detaching the LIB. In this case, the LIB separation work is easier than the case where the lid for attaching / detaching the LIB itself is not provided on the exterior of the portable device α, but when the lid is opened, only the LIB can be visually observed and gripped. In comparison, workability is clearly reduced.

  However, by applying this embodiment, even when a lid for attaching / detaching the LIB is not separately provided on the exterior of the portable device α, the LIB is prevented from being crushed without depending on only manual work. However, it is possible to recover the LIB. As a result, in order to increase the effect of the present embodiment, it is preferable that a lid for attaching / detaching the LIB is not separately provided on the exterior of the portable device α.

  As described above, in this embodiment, an example of LIB is given as the secondary battery. Of course, the present invention can be applied to other known secondary batteries.

[Embodiment 2]
In the second embodiment, a method for performing LIB separation by dropping a mobile device α (for example, a smartphone) from a high place will be described. As a processing target, a case will be described in which a portable device α in which a LIB is incorporated but a lid for attaching / detaching the LIB is not separately provided on the exterior is used. Note that those not described below are the same as those described in the first embodiment.

  In the battery separation process of the present embodiment, the LIB is separated from the portable device α by causing the portable device α after the predetermined acceleration to be given a predetermined speed to collide with the collision portion.

  The “predetermined acceleration” referred to here may be acceleration (ie, gravitational acceleration g) given by dropping the mobile device α by its own weight as exemplified in the present embodiment. Of course, the acceleration may be given by being skipped by the protrusion 42 in the processing apparatus described in the first embodiment.

  Further, the “predetermined speed” before the portable device α collides with the collision part may be a speed corresponding to the rotational speed described in the first embodiment.

  By the way, in the first embodiment, an example is given in which processing is performed on the mobile device α which is a tablet terminal (for example, a device having a touch panel display) incorporating a secondary battery (for example, LIB). It may be an example that is not limited to a terminal. However, in order to increase the effect of the present invention, it is preferable to process the portable device α in which a lid for attaching / detaching the LIB is not separately provided on the exterior.

  Next, an Example is shown and this invention is demonstrated concretely. Of course, the present invention is not limited to the following examples.

  In this example, a used smart phone (hereinafter simply referred to as “smart phone”) among the mobile devices was selected as a test target. Among them, iPhone (registered trademark) terminal (hereinafter referred to as terminal X) and Android (registered trademark) terminal (hereinafter referred to as terminal Y) were selected.

(Reference Example 1)
As a test, first, as Reference Example 1, the terminal X was manually disassembled.
A lid for attaching / detaching the LIB is not separately provided on the exterior of the terminal X. Therefore, it took about 15 seconds to remove the exterior (rear surface) of the terminal X. Further, the LIB of the terminal X is a laminate type battery pack, which is fixed by being adhered to the main body, and it took about 15 seconds to separate the LIB.
As a result, the total time for collecting the LIB from the terminal X was about 30 seconds.
In addition to the recovery of LIB, the time required for further recovery of the substrate from the terminal X was 100 seconds in total, and the time required to completely disassemble the terminal X was 200 seconds in total.

(Reference Example 2)
Similar to the above test, as Reference Example 2, the terminal Y was also dismantled manually. As the terminal Y, a test was performed on a terminal on which a square LIB was mounted and a terminal on which a laminate type battery pack was mounted as in the terminal X. Further, like the terminal X, a lid for attaching / detaching the LIB is not separately provided on the exterior of the terminal X.
As a result, the total time for collecting the LIB from the terminal Y was about 10 seconds when the LIB was square, and about 60 seconds when the LIB was a battery pack.

Example 1
In this example, a test was performed using the processing device for a portable device described in the first embodiment. In addition, the distance (W1) between the rotating body 4 and the collision part 6 in the processing apparatus was fixed to 100 mm. And the rotational speed of the surrounding surface of the rotary body 4 is 5 m / s (10 Hz), 7.5 m / s (15 Hz), 10 m / s (20 Hz), 15 m / s (30 Hz), 20 m / s (40 Hz), 25 m. Each case was tested as / s (50 Hz) and 30 m / s (60 Hz). In addition, a single terminal X is input to the processing apparatus.

  FIGS. 2A and 2B show photographs of the terminal X after processing and each part (including LIB) existing in the terminal X. FIG. 2A (a) to (d) and FIGS. 2B (e) to (g) respectively show rotational speeds of 5 m / s, 7.5 m / s, 10 m / s, 15 m / s, 20 m / s, and 25 m / s. , Corresponding to 30 m / s. 2A and 2B, in the case of the terminal X, LIB (parts surrounded by a dotted line in the figure) may be separated from the terminal X after the stage of FIG. 2A (c), that is, when the rotational speed is 10 m / s or more. did it. In addition, before the stage of FIG. 2B (f), that is, when the rotational speed was 25 m / s or less, excessive crushing such that the end of the LIB was missing did not occur. Even better, before the stage of FIG. 2A (d), that is, when the rotational speed was 15 m / s or less, damage to the LIB hardly occurred even though it was a battery pack.

(Example 2)
Using the same method as in Example 1, a test was performed on one terminal Y incorporating a square LIB. As a result, LIB could be separated from terminal Y when the rotational speed was 7.5 m / s or more.

(Example 3)
In this example, as in Example 1, the test was performed using the portable device processing apparatus described in Embodiment 1. In addition, the rotational speed of the surrounding surface of the rotary body 4 was 10 m / s (20 Hz). After that, three terminals X were continuously introduced into the processing apparatus.

FIG. 3 shows a photograph of the terminal X after the processing and the LIB existing therein. Referring to FIG. 3, the LIB could be separated from the terminal X. Moreover, even though LIB was a battery pack, almost no damage occurred.
In addition, the work time required only 3 seconds. Therefore, the cost required for the work can be reduced to about 1/6 of the reference example 1 using the terminal X even if the cost required for the controller of the apparatus and the input / transport of the terminal X is taken into consideration.

Example 4
Using the same method as in Example 3, the test was performed using the portable device processing apparatus described in Embodiment 1. In addition, 20 terminals X were continuously added to the processing apparatus.

FIG. 4 shows a photograph of the terminal X after the processing and the LIB existing therein. Note that only a few main bodies of the terminal X other than the LIB are displayed in FIG. 4 because of space. Referring to FIG. 4, LIB could be separated from 15 out of 20 terminals X. In other words, LIB could be efficiently recovered even when a large number of terminals X as many as 20 were continuously inserted. Moreover, even though the LIB was a battery pack, almost no damage occurred in any LIB.
In addition, the work time required only 3 seconds. Therefore, the cost required for the work can be reduced to about 1/6 of the reference example 1 using the terminal X even if the cost required for the controller of the apparatus and the input / transport of the terminal X is taken into consideration.

(Example 5)
Using the same method as in Example 3, the test was performed using the portable device processing apparatus described in Embodiment 1. Note that 16 terminals Y were continuously added to the processing apparatus.

FIG. 5A shows a photograph of the terminal Y after the processing, and FIG. 5B shows a photograph of the LIB existing in the terminal Y. Referring to FIGS. 5A and 5B, LIB could be separated from 14 out of 16 terminals Y. In other words, LIB could be efficiently recovered even when a large number of terminals Y such as 16 were continuously inserted. Moreover, almost no damage was caused in any LIB.
In addition, the work time required only 3 seconds. Therefore, the cost required for the work can be reduced to about 1/6 of the reference example 2 using the terminal Y even if the cost required for the controller of the apparatus and the input / transport of the terminal Y is taken into consideration.

  As a result of the above, according to the present embodiment, when recovering LIB from a used portable device, the LIB can be efficiently obtained without depending on only manual work and suppressing crushing of the LIB constituting the portable device. It was found to be recoverable.

In addition, when the content described so far is put together and the present invention is applied to as many portable devices as possible, the following configuration is obtained.
