  TECHNICAL FIELD The present invention relates to a screen protection sheet sticking device for portable electronic devices and a release sheet sticking device used for the screen protection sheet.

As represented by mobile terminals such as smartphones and tablets, recent portable electronic devices tend to increase those that use a display screen as an operation surface.
Under such circumstances, in order to prevent damage to the display screen of the portable electronic device, a screen protection sheet made of a transparent plastic film used by being attached to the display screen is becoming widespread.
In this screen protection sheet, an adhesive layer made of re-peelable glue is formed on the back surface to be attached to the screen. The adhesive layer may be provided on the entire back surface, or may be provided only on a part of the back surface such as near the edge of the screen protection sheet.
In any case, the release sheet is overlapped on the back surface of the screen protection sheet to cover the back surface so that the screen protection sheet before use does not stick to the other.
When using the screen protection sheet, the purchaser of the screen protection sheet peels off the release sheet from the back surface of the screen protection sheet and attaches the back surface to the screen of the portable electronic device.

However, in the above-mentioned pasting of the screen protection sheet to the screen of the portable electronic device, it is difficult and troublesome for an unfamiliar person or a clumsy person at hand to properly attach the screen protection sheet to the position where the screen is located. Work. For this reason, it often occurs that dust is caught between the screen and the screen protection sheet or that the screen protection film is wrinkled.
In view of such a situation, a screen protection film sticking aid shown in Patent Document 1 has been proposed.

  The screen protective film sticking aid shown in Patent Document 1 is a screen protective film sticking aid used for sticking a protective film for protecting the monitor screen to a monitor screen mounted on a device, wherein the monitor A removal object attached to the monitor screen is removed by attaching the frame to at least a part of the screen and a side surface of the screen and sliding the frame on the device.

However, in Patent Document 1, it is still necessary to manually perform the pasting operation on the screen. Moreover, although it is improved with the said sticking assistance tool, insertion of the protective film with respect to a sticking assistance tool must be performed by a user, and there exists a possibility that a wrinkle may arise depending on the direction and the method of insertion, and the speed of a slide.
Therefore, first of all, the present invention automatically sets a protective film, that is, a screen protection sheet and a portable electronic device to which the screen protection sheet is attached, at a predetermined position, and automatically without trouble. The present invention provides a sticking device for sticking a screen protection sheet to a screen of a portable electronic device to solve the above problems.
And secondly, the present invention particularly aligns the release sheet in the sticking device in order to accurately attach the screen protection sheet to the screen of the portable electronic device using the release sheet of the screen protection sheet. It is possible to carry out accurately.
Specifically, the coefficient of thermal expansion differs greatly between a plastic release sheet such as ABS resin and a metal device such as aluminum, and for example, ABS resin and aluminum are five times higher than a temperature change of 1 degree Celsius. There is a difference in thermal expansion coefficient. Therefore, due to changes in the climate and time of the area where the sticking device is used or the indoor environment such as air conditioning, there is a concern that the positioning of the release sheet cannot be accurately performed and the above automation is hindered.
For this reason, especially this invention aims at the solution of the said subject as what can position correctly with respect to a sticking apparatus about the peeling sheet provided in the sheet | seat for screen protection.

Devices, electronic dictionaries, portable reading devices for electronic books, portable navigation devices, notebook computers, digital cameras, portable televisions, portable music playback devices, and portable video playback devices.
The above "Paste the screen protection sheet to the screen" means whether to paste the screen protection sheet only on the screen, or to paste the screen protection sheet in a wider area including the screen, This includes the case where a screen protection sheet is pasted only on a part of the screen. For example, the screen protection sheet may be pasted over the entire screen in both cases where the entire surface of the portable electronic device is a screen and the other partial region of the surface is a screen. In contrast to the above, when the liquid crystal part or the pressure sensor part is provided only in a part of the screen, the screen protection sheet is attached only to the part of the screen, that is, the area requiring protection. It may be a thing.
Moreover, this invention can provide what took the next structure about the sticking apparatus of the screen protection sheet which sticks the screen protection sheet to the screen of portable electronic devices, such as a smart phone.
That is, the screen protection sheet is formed by forming a releasable adhesive layer on a part or the whole of the back surface to be attached to the screen, and a resin release sheet is overlapped on the back surface.

Moving toward the electronic device and pressing the back side of the screen protection sheet against the screen of the portable electronic device. In at least one step of the movement, the moving unit The screen protection sheet is moved in a direction substantially orthogonal to the thickness direction of the screen protection sheet with the one side of the screen protection sheet as the head, and moved in a direction substantially orthogonal to the thickness direction. During or before the movement, the peeling operation part moves relative to the holding part so as to intersect the head of the screen protection sheet, thereby moving the extension part to the screen protection sheet. The peeling sheet is turned from the top side of the screen protection sheet by pressing in the thickness direction of the screen, and after the turning, the peeling operation unit moves in a direction substantially orthogonal to the thickness direction. The sheet is moved in a substantially opposite direction relative to the movement of the sheet, and the rolled release sheet is gradually peeled from the back surface of the screen protection sheet, and the moving unit is configured to release the release sheet. It was possible to provide a device capable of moving the holding portion so as to press the back side of the screen protection sheet later to the screen of the portable electronic device.
Further, in the present invention, the device placement section has a device placement surface on which a portable electronic device can be placed, the holding portion includes a fitting portion, and the sheet placement surface and the device placement surface are Each includes a portion to be fitted that can be fitted into the mating portion, one of the mating portion and the portion to be mated is a recess, and the other of the mating portion and the portion to be mated is A convex portion that can be fitted into the concave portion, and the convex portion includes a guide portion that gradually decreases in diameter toward a tip of the convex portion, and the fitting portion is fitted in the fitting portion in the fitting portion. When the guide part comes into contact with the edge of the concave part and the convex part can be guided into the concave part, and the moving part stops the movement of the holding part, the mating part is brought close to the mating part. -The mating part can be displaced relative to the mating part in a direction intersecting with the direction of separation.

We can provide a screen protection sheet sticking device that has a joint. .

The present invention can provide a screen protection sheet sticking device for automatically sticking a screen protection sheet to a screen of a portable electronic device such as a smartphone.
In particular, in a screen protection sheet provided with a releasable glue adhesive layer on the back side to be attached to the screen, and the release sheet is overlapped on the back side, the release sheet can be peeled off smoothly, for screen protection. It was possible to suppress wrinkling on the sheet.
Furthermore, even if the alignment pin that forms the mating part is larger than the alignment hole that forms the mating part, the notch can be widened and the mating part can be forcibly mated. As a result, the release sheet can be reliably aligned with the sheet arrangement surface.
By providing a cut in the fitting portion that is the alignment hole in this way, a difference occurs in the size of the alignment pin that forms the fitting portion and the alignment hole that forms the fitting portion due to the difference in thermal expansion coefficient. Even if the fitted portion is not sized to fit the fitted portion, the fitted portion can be fitted to the fitted portion. In addition, by forming the notch of the fitting portion, the fitting portion can be pressed evenly toward the center of the diameter of the fitting portion by the elasticity of the exfoliated and peeled release sheet. The center axis coincides with the center axis of the fitting portion, that is, the centering action occurs, so that more accurate positioning can be performed. As an effect of the embodiment level, the action of the centering can be made particularly prominent by providing a plurality of notches in a radial pattern.
In addition, by providing a notch, it is possible to form the fitting part and the fitting part with the same diameter from the beginning without providing extra play in consideration of thermal expansion, and the influence of thermal expansion. Even in a normal state where there is no error, alignment can be performed with higher accuracy.

The fitted portion 32 is a protrusion provided on the sheet placement portion 3 so as to protrude and retract from the sheet placement surface 31 by a known means. Although illustration is omitted, for example, the sheet disposition unit 3 includes a cam mechanism driven by a motor, and the control unit controls the motor to operate the cam mechanism and accommodate the fitted portion 32. The present invention can be carried out by causing the sheet placement surface 31 to appear and disappear from within the receiving recess.
When the screen protection sheet m on the sheet arrangement surface 31 is adsorbed by the adsorption unit 51 described later, the control unit immerses the fitted part 32 from the sheet arrangement surface 31 and leaves the fitting part n3. Let

(Attaching part 5)
As shown in FIGS. 2A and 2B, the adhering unit 5 includes an adsorbing unit 51 as a holding unit that adsorbs and holds the surface m1 side of the screen protecting sheet m, and a moving unit 52 that moves the adsorbing unit 51. , One or a plurality of negative pressure supply units connected to the adsorption unit, and a plurality of valves 53.

  As illustrated in FIGS. 5A to 5C, the suction portion 51 includes a flat contact surface 51 c that faces the surface of the screen protection sheet m. The contact surface 51c is provided with a plurality of suction ports 51a and 51b. The negative pressure supply unit supplies negative pressure to the suction ports 51a and 51b, and adsorbs the surface m1 side of the screen protection sheet m to the contact surface 51c.

  Each of the suction ports 51a and 51b is distributed on the abutting surface 51c so as to be spaced apart from each other so as to correspond to the largest dimension of the screen protecting sheet m to be attracted. In this example, the minimum screen protection sheet m to be handled is for the smartphone k1, and as shown by a two-dot chain line in FIG. 5A, a part of the suction port (suction port 51a) is displayed in the region a corresponding to the screen g. ) Is distributed. In this example, the maximum screen protection sheet m to be handled is for the tablet k2, and all of the suction ports 51a and 51b are distributed in the area b corresponding to the screen g as shown by the broken line in FIG. . That is, since the region a is included in the region b, the suction ports 51a in the region a corresponding to the smartphone k1 are distributed together with other partial suction ports 51b in the region b corresponding to the tablet k2. It is also what you do.

The suction part 51 is a manifold having a passage extending in a branching manner from the connection part with the negative pressure supply part toward each of the plurality of suction ports 51a and 51b. The valve 53 is an electromagnetic valve.
When adsorbing the screen protection sheet m of the smartphone k1, some valves 53 block the supply of negative pressure to the other suction ports 51b among the suction ports 51a and 51b.

  That is, when adsorbing the screen protection sheet m having a size smaller than the maximum size of the screen protection sheet m, the valve 53 does not face the screen protection sheet m on the contact surface 51c as described above. The supply of negative pressure to the suction port 51b provided in the area (excluding the area a from the area b) is blocked.

  In this example, it is assumed that it corresponds to two types of smartphone and tablet, but can also be implemented as one corresponding to three or more types of portable electronic devices. In that case, in addition to areas a and b, other than smartphones and tablets An area corresponding to the screen of the portable electronic device may be set, and the number of suction ports and valves 53 corresponding to the area may be increased (illustration is omitted).

As shown in FIGS. 2A and 2B, the moving part 52 includes a piston part 52 a provided with the suction part 51 on the tip side, a cylinder part 52 b that accommodates the piston part 52 a in a retractable manner, and a case 1. And a guide 52c provided.
The guide portion 52c is a guide bar extending in the left and right directions L and R in FIGS. 2A and 2B, and the cylinder portion 52b is attached to the guide portion 52c. It is possible to move in the directions L and R. The guide portion 52c extends from above the sheet placement portion 3 toward above the device placement portion 2.

With the above configuration, the moving unit 52 can move the suction unit 51 in the lateral direction from the sheet arranging unit 3 toward the device arranging unit 2 along the guide unit 52c.
The piston part 52a can move up and down with respect to the cylinder part 52b by protruding and retracting from the piston part 52a. Further, in this example, the negative pressure generated in the cylinder portion 52b is adsorbed in the piston portion 52a when the piston portion 52a extends downward from the cylinder portion 52b. An intake passage leading to the portion 51 is provided (not shown). That is, in this example, the piston part 52a and the cylinder part 52b constitute the negative pressure supply part. However, in addition to using the piston part 52a and the cylinder part 52b as the negative pressure supply part, it is also possible to implement a structure in which an air pump is separately connected to the suction part 51 as the negative pressure supply part.

  The moving part 52 further lowers the suction part 51 that has reached the upper side of the device placement part 2 after the peeling sheet n is peeled off by the peeling mechanism part 4 by extending the piston part 52a, and the rear face m2 of the screen protecting sheet m. Can be pressed against the screen g of the portable electronic device k.

(Peeling mechanism part 4)
As shown in FIGS. 2 (B), 4 (B), and 8 (A), the peeling mechanism unit 4 removes the release sheet n from the screen protective sheet m while the moving unit 52 moves the screen protective sheet m. It peels from the back surface m2. In this example, the peeling mechanism unit 4 peels the peeling sheet n from the back surface m2 of the screen protection sheet m while the screen protection sheet m is moving from the left side L to the right side R in FIG. Let
Specifically, the peeling mechanism unit 4 includes a peeling operation unit 41, an operation unit 42, a shaft stopping unit 43, a receiving unit 44, a driving unit 45, and a discharge guide unit 46.
In this example, the peeling operation unit 41 is a free roller, the operation unit 42 is two arms that rotatably hold the roller, and the shaft stopper 43 pivotally stops the arm. .

  Between the tips of the two arms of the operating portion 42, the roller as the peeling operation portion 41 is rotatably held (FIG. 4B). The shaft stopper 43 pivots the base side of the two arms of the operating portion 42. The shaft stopper 43 obtains power from a power source (not shown) such as a motor and swings the two arms around the base side. By this swinging, the roller as the peeling operation unit 41 moves from the upper side to the lower side with respect to the traveling direction of the screen protection sheet m during the movement from the left L to the right R in FIGS. 2 (B) and 8. And can cross. The receiving portion 44 is a rotating roller that rotates upon receiving power from the driving portion 45. The driving unit 45 employs known driving means such as a motor. The rotating roller which is the receiving portion 44 is fixed at a fixed position of the case 1. The rotating roller that is the receiving portion 44 can sandwich the release sheet n with the roller of the peeling operation portion 41 that has been lowered by the swing. The discharge guide part 46 guides the release sheet n peeled from the screen protection sheet m to the vicinity of the third opening / closing part 13.

  As described above, during the movement from the left L to the right R in FIG. 2B, that is, during the movement in the direction substantially perpendicular to the thickness direction of the screen protection sheet m, the peeling operation unit 41 is moved to the suction unit 51. By moving relative to the head of the screen protection sheet m, the front extending portion na is pressed in the thickness direction of the screen protection sheet m, that is, downward, to release the release sheet n. It is possible to hit from the head side of m.

  After the turning, the peeling operation unit 41 moves in a direction substantially opposite to the movement of the screen protection sheet m moving in the direction substantially orthogonal to the thickness direction, and the rolled release sheet n is used for screen protection. The sheet m is gradually peeled off from the back surface. This relatively reverse direction means that the screen protection sheet m is moving, and the peeling operation unit 41 does not necessarily move in the opposite direction to the screen protection sheet m with respect to the case 1. You don't have to.

(Power supply part)
The power supply unit supplies electricity from an external commercial power supply to the internal mechanism through the power cord. However, the battery is not limited to a commercial power source, and a battery may be used.

(Control part)
A control part receives supply of electricity from a power supply part, controls supply of electricity to each drive means and power source which have been described above, and controls operation of each part of the sticking apparatus.
Although illustration is omitted, a sensor is connected to the control unit, and the operation timing of each unit can be detected to match the operation timing of each unit. For example, when a light sensor composed of a light emitting part and a light receiving part is provided in the movement path between the suction part 51 and the suction part 51 in the case 1, the light receiving part receives light emitted from the light emitting part, or the light receiving part However, it can also be implemented by causing each unit to start the next operation with reference to the time when the light of the light emitting unit that has been received is blocked. Moreover, it can implement also as what uses physical sensors, such as a pressure-sensitive sensor, instead of such an optical sensor. Furthermore, a servo motor can be adopted as each driving means and power source, and the direction of the rotating shaft and the number of rotations of the motor can be detected to detect the operation timing of each part. In addition, the control unit may be provided with a timer to detect the passage of time from the start of operation and to determine the operation timing of each unit.

(Operation of equipment)
The operation of the device will be described.
By the operation of the operation unit, the power supply unit is turned on, the fan 14 is operated, and the inside of the case 1 is brought into a pressurized state.

  At the start of use of the apparatus, the suction unit 51 is arranged directly above the arrangement surface 21 of the device arrangement unit 2 by the moving unit 52. That is, the suction part 51 is in the same position as shown in FIG. However, unlike the case of FIG. 7B, the suction portion 51 is retracted upward from the placement surface of the device placement portion 2 without sucking the screen protection sheet m, and the portable electronic device k is also placed in the device placement. It is not on the arrangement surface 21 of part 2. At this time, the fitted portion 32 of the sheet arrangement portion 3 protrudes from the sheet arrangement surface 31 as shown in FIG. Further, the shaft stopping portion 43 of the peeling mechanism portion 4 maintains the state where the distal end side of the operating portion 42 is directed downward and the peeling operation portion 41 is disposed below the sheet placement surface 31.

  A user opens the door of the 1st opening-and-closing part 11, and pulls out the apparatus arrangement | positioning part 2 to this side along the guide rail 24 (FIG.2 (B)). As shown in FIG. 3B or FIG. 4A, the portable electronic device k is placed at a predetermined position on the placement surface 21 of the device placement unit 2. In the arrangement, the position of the portable electronic device k is appropriately adjusted to a predetermined position on the arrangement surface 21 of the device arrangement unit 2 by the contact portion 22 described above. After the arrangement, the pulled out device arrangement portion 2 is returned to the original case 1 and the first opening / closing portion 11 is closed.

  In the case of the tablet k2, the tablet k2 is placed on the placement surface 21 as shown in FIG. 4 (A), and then the user opens the second opening / closing part 12 to open the tablet k2 as shown in FIG. 4 (B). As shown in FIG. 5, the screen protection sheet m is arranged on the sheet arrangement surface 31 of the sheet arrangement unit 3. In this arrangement, the protruding portion to be fitted 32 is fitted into the fitting portion n3 of the release sheet n on the back surface m2 of the screen protection sheet m, so that the screen protection sheet m is surely placed at a predetermined position on the sheet placement surface 31. Can be arranged. After the arrangement of the screen protection sheet m, the second opening / closing part 12 is closed.

When the arrangement of the portable electronic device k and the screen protection sheet m is completed, the user operates the operation unit to cause the sticking apparatus to start sticking work.
In response to the operation of the operation unit, the control unit causes the moving unit 52 to move the suction unit 51 directly above the sheet arrangement surface 31 of the sheet arrangement unit 3.

When the control unit detects the arrival of the suction unit 51 directly above the sheet arrangement surface 31 by the above-described sensor or timer, the control unit detects the shaft stop portion of the peeling mechanism unit 4 as shown in FIG. 43 is operated to swing so that the front end side of the operating portion 42 faces upward, and the peeling operation portion 41 is moved upward from the sheet placement surface 31.
And a control part makes the state to which the to-be-fitted part 32 was sunk from the sheet | seat arrangement | positioning surface 31, and removes the to-be-fitted part 32 from the fitting part n3.

Next, as shown in FIG. 7B, the control unit extends the tip of the piston portion 52a of the moving unit 52 downward to lower the suction unit 51, and the contact surface 51c to the surface m1 of the screen protection sheet m. Make contact. During this contact, the valve 53 (solenoid valve) is opened. The surface m1 of the screen protecting sheet m is sucked into the suction ports 51a and 51b by the negative pressure from the negative pressure supply unit, and is sucked and held by the suction unit 51.
After the screen protection sheet m is adsorbed, the control unit swings so that the distal end side of the operating unit 42 is directed downward by the operation of the shaft stopping unit 43, and the roller serving as the peeling operation unit 41 is received by the receiving unit 44. Contact a rotating roller.

  As shown in FIG. 6C, the above-described operation of the peeling operation unit 41 sandwiches the front extending portion na of the peeling sheet n between the peeling operation unit 41 and the receiving unit 44. As shown in FIG. 8A, the rotating roller that is the receiving portion 44 is located on the left side of the front end, that is, the right end of the sheet placement surface 31 of the sheet placement portion 3. For this reason, during the operation of the peeling operation unit 41, the peeling sheet n is smoothly rolled from the screen protection sheet m to the lower left side.

  As described above, when the front extending portion na of the release sheet n is sandwiched between the peeling operation unit 41 and the receiving unit 44, the control unit rotates the receiving unit 44 by driving the driving unit 45. Further, simultaneously with the rotation of the receiving unit 44, the control unit operates the moving unit 52 to start moving the suction unit 51 in the lateral direction, that is, the right direction R. The speed of movement of the suction part 51 and the speed of feeding the release sheet n due to the rotation of the receiving part 44 are set to be the same. Due to the coincidence of the speeds, the release sheet n is smoothly peeled off as shown in FIG. As shown in FIG. 7B, the separated separation sheet n is guided to the discharge guide portion 46 and dropped to the vicinity of the third opening / closing portion 13.

  When the control unit detects that the suction unit 51 has moved directly above the arrangement surface 21 of the device arrangement unit 2 as shown in FIG. 7B, the control unit, as shown in FIG. The moving part 52 lowers the suction part 51 and presses the screen protection sheet m against the screen g of the portable electronic device k, closes the valve 53 to release the negative pressure, and moves to the screen g of the portable electronic device k. A screen protection sheet m is pasted.

  Due to the inclination of the guide rail 24 described above, in the screen protection sheet m of the suction portion 51, the rear B side slightly floats from the front F side with respect to the screen g. For this reason, when the suction part 51 is pulled away, the rear B side of the screen protecting sheet m falls toward the screen g by its own weight, and the rear B side is gradually pasted to the screen g after the front F side. By gradually sticking to the screen G from the front F side to the rear B side in this way, the screen air is gradually removed from between the screen g and the screen protection sheet m for screen protection. Sheet m can be pasted.

After sticking the screen protection sheet m, the control unit causes the moving unit 52 to raise the suction unit 51 from the arrangement surface 21 of the device arrangement unit 2.
As described above, each time the screen protection sheet m of one portable electronic device k is attached, one corresponding independent screen protection sheet m is set in the attaching device. By handling the protective sheet cut according to the device, it is possible to quickly and flexibly cope with portable electronic devices of various sizes and shapes.

(Example of change)
The moving unit 52 can be implemented by other known means as long as the above-described movement of the adsorption unit 51 is possible. For example, it can be implemented by moving the suction portion 51 from the suction to the screen g by displacing the suction portion 51 in a guide groove (not shown) by a known cam mechanism. By using the cam mechanism in this way, the device can be reduced in size.

However, it is also possible to configure and implement the moving unit 52 other than the illustrated one or the cam mechanism.
Further, the peeling mechanism unit 4 is not limited to the roller as the peeling operation unit 41, but can be implemented by using another pressing member to roll the peeling sheet n.

  When the screen protection sheet m is pasted on the screen g, the suction port of the suction portion 51 simultaneously shuts off suction by the valve 53, and in front of FIG. 2B (front F of FIG. 5A). The suction port located on the back side (the rear B in FIG. 5A) side of the suction port located on the) side can be controlled so as to release the suction with a gradual delay. As described above, when the suction of the suction port is canceled from the front side to the back side with a time difference, air can be smoothly discharged from between the screen protection sheet m and the screen g. The corresponding valves 53 are different between the suction ports at different positions between the front side and the back side so that the suction can be released due to the time difference, and the valve closing operation from the control unit to each valve 53 is performed. A plurality of command systems may be provided separately.

The screen protection sheet m does not need to be deformed like the release sheet n, and a material that is not easily deformed, such as a glass plate, can be employed in addition to the plastic film.
The release sheet n may be any material that can be rolled by the peeling operation unit 41. In addition to the plastic film, a deformable material such as a paper sheet can be used.

  Further, in the example described above, the holding unit is the suction unit 51 that sucks and holds the screen protection sheet with negative pressure. However, the holding unit is not limited to the negative pressure, and the screen protection sheet is used. As long as it can be appropriately held, it is possible to adopt a configuration other than the suction unit 51, such as an adhesive unit that holds a sheet by adhesion or a known gripping device that holds a sheet by picking a screen protection sheet. Note that the holding unit may generate a negative pressure to the suction unit 51 with a pump instead of the mechanism described above.

(Other embodiments)
Hereinafter, with reference to FIG. 9 to FIG. 18, the portable electronic device k on which the screen protection sheet m is pasted on the liquid crystal screen is exemplified for use on a smartphone.

That is, each fitting part n3 of the front extension part na is provided with three notches n4, and each fitting part n3 of the side extension part nb is provided with four notches n4. However, the configuration of each fitting portion n3 and the number of notches n4 can be changed as long as the operation of centering described later can be appropriately obtained. For example, the present invention can be implemented by providing a fitting portion n3 having five or more notches n4.
In this example, one of the fitting portions n3 is fitted into a fitting portion 32 that also serves as a mating portion bb described later. That is, one of the fitting portions n3 provided in the side extending portion nb shown in FIGS. 12A and 15 is fitted into the fitting portion 32 that also serves as the mating portion bb. Specifically, as shown in FIG. 15, of the two fitting parts n3 provided in the side extension part nb, the fitting part n3 provided on the front side in the sheet traveling direction, that is, near the right side R of the apparatus, is covered. It is fitted to the fitting part 32 that also serves as the fitting part bb.
In the extended portion of the release sheet n, the fitting portion n3 different from the fitting portion 32 that also serves as the mating portion bb, that is, the region where the fitting portion n3 that does not serve as the mating portion bb is provided. As a contact area, the sheet does not come into contact with the contact surface 51c of the suction part 51 even when the sheet is suctioned by the suction part 51 described later (FIG. 16). In this example, in the extension portion, the region where the fitting portion n3 that does not serve as the portion to be fitted bb of the side extension portion nb and the front extension portion na are the non-contact region.

By changing any of the position of the release sheet n overlapping the screen protection sheet m, the size of the release sheet n, the shape of the release sheet n, and the position of the fitting portion n3 in the release sheet n Changes in the size or shape of the sheet, that is, the adjustment work on the apparatus side required for the change in the portable electronic device k can be reduced. In particular, the size and shape of the screen protection sheet m are changed. Even if the position of the release sheet n overlapping the screen protection sheet m is changed, by providing the fitting portion n3 at a position that can correspond to each change from the beginning, in the above change, the dimensions of the release sheet n, the release sheet n This is the same as the embodiment shown in FIG. 4B, in that it can be handled without changing the shape and the position of the fitting portion n3.
Moreover, although the screen protection sheet m for smartphones was illustrated, for example, when the screen protection sheet m for tablet terminals is used, as described above, the change of the dimension of the release sheet n and the fitting portion as well as the screen protection sheet m What is necessary is just to respond | correspond by changing the number and arrangement | positioning of n3.

In a state where the portable electronic device k is arranged on the device arrangement surface 21, the mating portion aa has a height that protrudes upward from the portable electronic device k and the contact portion 22.
The mating portion aa is a pin provided with a guide portion t1 that gradually decreases in diameter toward the tip, that is, the apex thereof (FIGS. 9A and 9B). The guide part t1 is a tapered surface that tapers the to-be-filled portion aa, and the guide part t1 has a substantially conical shape. By making the inclination of the taper surface steep, it is possible to align the screen protection sheet m with higher accuracy to the screen g.
However, the guide part t1 can also be implemented as a hemispherical or spindle-shaped upper half or even a contour having a curved shape in a side view, such as Mt. Fuji. Moreover, the number and arrangement | positioning of the to-be-filled part aa are not limited to the above, It can change into the other position and other number of the apparatus arrangement | positioning surfaces 21. FIG.

(Sheet placement part 3)
The sheet placement portion 3 shown in FIGS. 9A and 10 is a table whose upper surface is a sheet placement surface 31, and is fixed to the case 1 so that it can be pulled out from the case 1 in this example.
In the plan view of the sticking device, the sheet placement unit 3 is located on the opposite side of the device placement unit 2 (in this example, the left side L of the device placement unit 2) across the peeling operation unit 41 and the receiving portion 44 of the peeling mechanism unit 4. Is provided.

Also in this embodiment, as shown in FIG. 9A and FIG. 10, a plurality of fitted portions 32 are provided on the sheet arrangement surface 31. Each of the fitted portions 32 is fitted into the fitted portion n3 of the peeled sheet n as shown in FIGS. 12D and 12G and positions the screen protection sheet m on the sheet placement surface 31. In this respect, the fitted portion 32 is the same as that shown in FIG. However, in the embodiment shown in FIGS. 9 to 18, the fitted portion 32 is fixed at a fixed position on the sheet arrangement surface 31 in a plan view, and does not appear or disappear, that is, fixed vertically. It is.
The fitted portion 32 is a pin provided with a guide portion t3 that gradually decreases in diameter toward the tip, that is, the apex thereof. The guide part t3 is a tapered surface that tapers the fitted portion 32, and the guide part t3 has a substantially conical shape. The guide part t3 can also be implemented as a hemispherical, spindle-shaped, or Mt.
However, since the user may touch the fitted portion 32, it is preferable to make the tapered surface gentler than the fitted portion aa.
The guide part t3 can be rounded like the fitted part 32 shown in dark color in FIGS. 12D and 12G.
Furthermore, the sheet arrangement surface 31 also includes a mating portion bb that is fitted into the mating portion cc. In the sheet arrangement surface 31, the mating portion bb is provided at a position facing the mating portion cc of the holding portion when the screen protection sheet m is held by the holding portion. The mating portion bb of the sheet arrangement surface 31 also has the same shape as the mating portion aa of the device arrangement surface 21. However, since the user may also touch the filled portion bb of the sheet arrangement surface 31, it is preferable that the tapered surface is made gentler than the filled portion aa.
In particular, in this embodiment, as shown in FIGS. 10 and 15, one of the fitted portions 32 also serves as the fitted portion bb. In this example, one of the fitted parts 32 fitted to the fitting part n3 provided in the side extending contact part nb of the release sheet n also serves as the fitted part bb.
However, the mating portion bb can be implemented even if it is provided separately from the mated portion 32 and does not serve as the mated portion 32.
In addition, the number and arrangement | positioning of the to-be-fitted part 32 are not limited to the above, It can change into the other position and other number of the apparatus arrangement | positioning surface 21. FIG.

(Attaching part 5)
The sticking unit 5 includes a moving unit 52. The moving unit 52 moves the suction unit 51, that is, the holding unit from above the sheet arrangement surface 31 to above the device arrangement unit surface 31, and moves the holding unit up and down. The point provided with the vertical movement mechanism to be made is the same as that of embodiment shown in FIGS. That is, the screen moving sheet m can be held by the vertical movement mechanism moving the holding portion up and down in a state where the horizontal movement mechanism has arranged the suction portion 51, that is, the holding portion above the sheet arrangement surface 31. During the movement from the upper side of the sheet arrangement surface 31 to the upper side of the device arrangement part surface 21, the peeling from the back surface of the screen protection sheet m of the peeling sheet n is performed.
In this example, unlike the embodiment shown in FIGS. 1 to 8, the moving part 52 does not include the piston part 52a and the cylinder part 52b. Specifically, as shown in FIGS. 11A to 11D, the moving unit 52 includes a casing 54 that is provided integrally with the guide unit 52 c, an elevating drive unit 52 b that is attached to the casing 54, and an elevating unit. An elevating shaft 52a assembled to the drive unit 52b, a guide shaft 55, a support shaft 56 that supports the adsorption unit 51, and a holding plate 57 fixed to the tip of the elevating shaft 52a are provided. The negative pressure is supplied to the suction part 52 by connecting a tube (not shown) connected to the suction part 52 directly to a pump (not shown) installed in the sticking apparatus. In this example, the raising / lowering drive part 52b is a direct acting motor provided as a vertical movement mechanism, and the motor shaft assembled to the direct acting motor is the raising / lowering shaft 52a.
At the bottom of the casing 54, there are provided a through-hole through which the lifting shaft 52a passes and protrudes downward from the casing 54, and a through-hole through which the guide shaft 55 passes. The lower end of the guide shaft 55 is fixed to the holding plate 57, and the guide shaft 55 protrudes and retracts from the casing 54 through the through hole by the lifting and lowering of the lifting shaft 52a. The raising and lowering of the holding plate 57 by the raising and lowering of the raising and lowering shaft 52a is guided by the protrusion and depression. In this example, four support shafts 56 are fixed to the upper surface side of the suction portion 51 with a space between the front, rear, left and right. However, the number of support shafts 56 is not limited to four, and two, three, or five or more can be implemented as long as the suction portion 51 can be appropriately supported. The holding plate 57 includes a through portion through which the support shaft 56 passes. A stopper is provided on the upper end side of the support shaft 56 so that the support shaft 56 does not fall downward from the through portion. The retaining member includes a seating surface that comes into contact with the upper surface of the holding plate 5. The support shaft 56 is suspended from the holding plate 57 by the retaining. For this reason, after the suction part 52 comes into contact with the screen protection sheet m on the sheet arrangement surface 31 by the lowering of the lifting shaft 52c, the support shaft 56 moves backward from the holding plate 57 to the suction part 52 more than necessary. The screen protection sheet m is not pressed.
The mating portion cc and the mating portion aa include the clearance for mounting the support shaft 56, the clearance for swinging the motor shaft that is the lifting shaft 52a, the clearance between the rail 52c and the casing 54 provided on the guide portion 52c, and the like. The mating portion cc can be displaced in a direction intersecting with the approaching / separating direction and in a direction intersecting with the approaching / separating direction between the mating portion cc and the mating portion bb.
Although illustration is omitted, the position corresponding to the non-contact region of the side extending portion nb of the release sheet n on the contact surface 51c of the suction portion 51 retreats upward or receives the fitted portion 32. What is necessary is just to set it as an avoiding part which avoids contact | abutting with the to-be-fitted part 32, forming as a pin hole similar to the fitting part cc to do. In this example, the avoidance part is a pin hole.

(Peeling mechanism part 4)
In this embodiment, the peeling mechanism portion 4 includes a receiving portion holding body 47 together with a peeling operation portion 41, an operating portion 42, a shaft stopping portion 43, a receiving portion 44, a driving portion 45, and a discharge guide portion 46.
In this example, the peeling operation part 41 is a free roller that is axially fixed to the operating part 42 by the axial stop part 43. The shaft stop portion 43 is a hole provided in the operation portion 42 and receives the shaft of the roller. The operating portion 42 is a frame that holds the roller in a rotatable manner and engages with a link member (not shown) to operate up and down.

The roller which is the peeling operation unit 41 is rotatably held between the pair of shaft stop portions 43 provided in the operation unit 42 (FIGS. 9 and 13). The operating portion 42 is fixed to the link member and can move up and down with respect to the sheet placement portion 3 by swinging of the link member. The swing of the link member is linked directly or indirectly to any of the members that support the suction portion 52 so as to be interlocked with the lateral movement of the suction portion 52 by the moving portion 51 ( (Illustrated).
However, as long as it is possible to cause the roller to perform a peeling operation as the peeling operation unit 41, a mechanism other than moving the operation unit 42 up and down by the link member can be employed. For example, as in the embodiment shown in FIGS. 1 to 8, the arm having the roller fixed on the distal end side is referred to as the operating portion 42, and the base end side of the operating portion 42 is axially fixed to the peeling device. It can also be implemented as a roller that moves up and down by turning. In this case, as will be described later, like the receiving portion 44 receiving the driving force from the driving portion 45, the arm may be rotated by receiving the driving force transmitted from the driving portion 45, or a separate independent motor or the like. It is good also as what turns by obtaining motive power from a power source (not shown).
In this example, the roller of the peeling operation unit 41 that moves up and down as the peeling operation of the operating unit 42 protects the screen during movement from the left L to the right R as indicated by a thick arrow in FIG. As shown in FIG. 14 (A), the traveling direction of the sheet m can be moved from the upper side to the lower side to intersect. The receiving portion 44 is a rotating roller that rotates upon receiving power from the driving portion 45. The driving unit 45 employs known driving means such as a motor. The rotating roller which is the receiving portion 44 is fixed at a fixed position of the case 1. The rotating roller as the receiving portion 44 can sandwich the release sheet n between the roller of the peeling operation portion 41 that has been lowered. The discharge guide part 46 guides the release sheet n peeled from the screen protection sheet m to the vicinity of the third opening / closing part 13.

  As described above, during the movement from the left side L to the right side R in FIG. 13C, that is, during the movement in the direction substantially perpendicular to the thickness direction of the screen protection sheet m, the peeling operation unit 41 is shown in FIG. As shown in A), the front extending portion na is pressed in the thickness direction, that is, the lower side of the screen protection sheet m by moving so as to intersect the head of the screen protection sheet m relative to the suction portion 51. The release sheet n can be rolled from the top side of the screen protection sheet m.

  After the turning, the peeling operation unit 41 moves in a direction substantially opposite to the movement of the screen protection sheet m moving in the direction substantially orthogonal to the thickness direction, and the rolled release sheet n is used for screen protection. The sheet m is gradually peeled off from the back surface. This relatively reverse direction means that the screen protection sheet m is moving, and the peeling operation unit 41 does not necessarily move in the opposite direction to the screen protection sheet m with respect to the case 1. You don't have to.

(Operation of equipment)
In the operation of the apparatus shown in FIGS. 9 to 18, the basic operation of each part of the apparatus is the same as that of the embodiment shown in FIGS. Here, it demonstrates centering on the difference of the said operation | movement. As shown in FIGS. 9B and 15, the user pulls out the sheet placement portion 3 from the case 1, aligns the fitting portion n <b> 3 with the tip of the fitted portion 32, and protects the sheet placement surface 31 for screen protection. Place the sheet m and lightly press the screen protecting sheet m downward. At this time, the fitted portion 32 is fitted to the fitted portion n3 by the weight of the screen protecting sheet m and the pressing force of the user's fingertip. In this fitting, even if the fitted portion 32 does not fit the inner diameter of the fitting portion n3 due to thermal expansion or expansion / contraction of the screen protection sheet m, as shown in FIGS. n4 is expanded and opened, and the fitting portion n3 can receive the fitted portion 32. In the fitting, the above-described centering action is obtained.
Then, as shown in FIG. 15, the portable electronic device k is set on the device arrangement surface 21 of the device arrangement unit 2.

When the setting of the screen protection sheet m and the portable electronic device k is completed, the sticking device is activated.
As shown in FIGS. 13 to 14 and FIGS. 16 to 18, the screen protection sheet m is attached to the portable electronic device k through basically the same steps as those of the embodiment of FIGS. 1 to 8. Is done. During the stroke, the suction part 51 descends to hold the screen protection sheet m, and then the mating part bb is pulled out from the mating part cc and the mating part 32 is pulled out from the fitting part n3. And while the adsorption | suction part 51 moves to the horizontal direction in the moving part 5, as shown to FIG. 14 (A), the action | operation part 42 holding the peeling operation | movement part 41 by the interlocking | linkage with a link member (not shown) is concerned. The peeling operation unit 41 is moved linearly from the thickness direction of the screen protecting sheet m crossing the movement, that is, from the upper side to the lower side, and the peeling of the sheet is started. After the sheet is peeled off, the mating portion cc is guided to the mating portion bb of the device arrangement portion 2, and the screen protection sheet m is pasted.
In the above process, the negative pressure of the suction part 51 is generated by the pump, and the fitted part 32 does not sink when the sheet is held by the suction part 51. The point of shifting to the peeling operation after separating from the point, the point of the peeling operation due to the linear movement of the peeling operation unit 41, and the adsorbing part 51 and the sheet arrangement surface using the mating parts aa, bb and the mating part cc 31 and the device arrangement surface 21 are different from the embodiment shown in FIGS. Except for the above-described differences, the embodiment shown in FIGS. 9 to 18 is the same as the embodiment shown in FIGS.
1 to 8, the same as the embodiment shown in FIGS. 9 to 18, the mating portion cc and the mating portions aa and bb are provided, and the adsorbing portion 51 is lowered. After holding the screen protection sheet m, the mating portion bb is pulled out from the mating portion cc by rising, and the mating portion 32 is pulled out from the mating portion n3. When adopting a configuration in which the fitted portion 32 is removed from the fitted portion n3, the fitted portion aa is fitted to the device arranging portion 2 and the sheet arranging portion 3 is also fitted in the embodiment shown in FIGS. The portion bb can be carried out by providing a fitting portion cc to the suction portion 51, that is, the holding portion.

In the above, the positioning in the sheet placement unit 3 and the device placement unit 2 is performed by the pins (the mating portions aa and bb) provided in the sheet placement unit 3 and the device placement unit 2 and the pin holes provided in the suction unit 51. By performing the fitting with the (mating portion cc), the pasting error can be minimized, and the holding portion can be guided to the correct position.
It should be noted that the mating portions aa and bb and the mating portion cc can be reversed, that is, the mating portions aa and bb can be pin holes and the mating portion cc can be a pin.

Further, the hole of the sheet to be fitted, that is, the fitting part n3 has the same diameter as the pin provided on the sheet placement part 3, that is, the outer diameter of the fitted part 32, and a slit or notch n4 is provided in the sheet hole. This makes it difficult for misalignment to occur at the time of sheet installation, and minimizes a pasting error due to misalignment at the time of sheet layout.
In particular, when the screen protection sheet m is arranged at an appropriate position in the fitted portion 32 by not providing the fitting portion n3 arranged in the release sheet n with play with respect to the fitted portion 32. In addition, as shown in FIGS. 12D and 12G, the periphery of the hole of the release sheet n is lifted by slits or cuts n4 that are evenly arranged around the fitting portion n3 that is a positioning hole, and the fitting is completed. Since the lifted release sheet n has a restoring force that keeps the positioning pin, that is, the fitted portion 32 in the center of the fitting portion n3, by the cuts n4 that are evenly arranged on the circumference, the sheet is displaced when the sheet is placed. Is unlikely to occur.
In addition, as described above, the suction portion 51 is guided to the correct position of the sheet placement portion by the mating portion bb and the mating portion cc, that is, the fitting pin and the fitting pin hole, and sucks the screen protection sheet m. can do.
As shown in FIGS. 14A, 14B, and 17, the release sheet n that has been positioned is removed, but the appropriate information on the position of the screen protection sheet m, that is, the positional relationship, is determined by the fitting pin hole. 18, the adsorbing portion 51 is guided to the correct position of the device placement portion 3 by the fitting pin and the fitting pin hole.
In terms of the accuracy of the fitting, as shown in FIG. 12, the fitting portion n3 is provided with three or more cuts n4 provided radially at equal intervals, but in addition, the fitting portion n3 Also, the present invention can be implemented by providing one or two notches n4. Moreover, when the fitting part n3 is provided with two or more cuts n4, it is preferable that the cuts n4 are equally spaced from each other.
That is, it is as follows when the fitting part n3 is summarized.
1) In order to prevent the screen protection sheet m from being rotated and placed when the screen protection sheet m is set, no margin is provided between the fitting portion n3 of the release sheet n and the fitting portion 32. Is preferred.
2) Since the notch n4 is provided in the one fitting portion n3, the fitting portion 32 that is a fitting pin does not enter the release sheet n by not providing the margin, or the fitting portion n3 of the release sheet n. Can be avoided.
3) As described above, there is no problem in setting the release sheet n even if the number of slits that are the cuts n4 is one or two, but by arranging three or more on the circumference, the cuts n4 are springs. Thus, the function of centering can be remarkably exhibited, and the screen protection sheet m can be set more accurately.
