[0005] Patent Literature 1: Japanese Patent Application Publication No. 2015-60878 SUMMARY

[0006] PROBLEMS TO BE SOLVED BY THE INVENTION

[0007] In the sheet attaching device disclosed in Patent Literature 1, the correcting unit corrects the adhesive sheet in a manner along the support surface before the adhesive sheet is attached to the adherend. Thereby, it is possible to prevent the adhesive sheet in a state having a wrinkle from being held by the holding mechanism. Therefore, in the sheet attaching device disclosed in Patent Literature 1, the corrected adhesive sheet is attached to the adherend. However, even when the adhesive sheet is attached to the adherend in a state without a wrinkle, air sometimes enters between the adhesive sheet and the adherend. In this case, when air enters between the adherend and the adhesive sheet, a bubble is generated, and thus there is a possibility that the appearance and the function are impaired. Therefore, it is required to provide a sheet attaching device capable of suppressing entry of a bubble between the adherend and the adhesive sheet.

[0008] An object of the present application is to provide a sheet attaching device capable of suppressing entry of a bubble between an adherend and an adhesive sheet.

[0025] <EMBODIMENT>

[0026] (adhesive sheet attaching device)

[0027] The following describes the general outline of the adhesive sheet pasting device 1 according to the embodiment. First, the adhesive sheet pasting device 1 cuts out an adhesive sheet 5 and pastes the cut-out adhesive sheet 5 onto the object to be pasted 6. Then, the adhesive sheet pasting device 1 presses the adhesive sheet pasted onto the object to be pasted 6. Thus, the adhesive sheet pasting device 1 includes a portion for cutting out the adhesive sheet, a portion for pasting the adhesive sheet, and a portion for pressing the adhesive sheet.

[0028] The adhesive sheet 5 is adhered to the adhesive surface 6a of the object to be adhered to 6. The adhesive sheet application device 1 cuts the adhesive sheet 5 to a length that does not protrude from the adhesive surface 6a. Figure 1A This diagram illustrates an example of attaching the adhesive sheet 5 to the object to be bonded 6 according to the embodiment. As shown in FIG1, one side of the adhesive sheet 5 is an adhesive layer 5a. The adhesive layer 5a is bonded to one side of the object to be bonded 6. For example, the object to be bonded 6 is a cuboid magnet. In this way, for example, the adhesive sheet 5 can be bonded to the magnet. This reduces the amount of air bubbles generated between the magnet and the adhesive sheet 5. Here, the adhesive sheet 5 is bonded to the widest surface of the object to be bonded 6.

[0029] For example, a magnet with adhesive sheet 5 attached is inserted into a magnet insertion hole 91 that runs through the rotor core 9 along the axial direction. That is, the object to be attached 6 can also be a rotor magnet 61 inserted into the rotor core 9. Figure 1B This illustrates an example of a rotor core 9 with a magnet insertion hole 91. Figure 1B A rotor magnet 61 is inserted into the magnet insertion hole 91 of the rotor core 9 shown. For example... Figure 1B As shown, the rotor core 9 extends axially and is cylindrical. The direction parallel to the central axis P of the rotor core 9 is the axial direction.

[0030] Then, the adhesive sheet 5 is attached to the rotor magnet 61. Figure 1C This is a diagram illustrating an example of the adhesive sheet 5 involved in the embodiment. (See diagram below.) Figure 1C As shown, the adhesive sheet 5 is stacked in the thickness direction in the following order: substrate sheet 5b, rotor core-side foam sheet 5c, magnet-side foam sheet 5d, and adhesive layer 5a. The substrate sheet 5b, rotor core-side foam sheet 5c, magnet-side foam sheet 5d, and adhesive layer 5a are all sheets of the same size when viewed from above. The side of the magnet-side foam sheet 5d opposite to the substrate sheet 5b side is the adhesive layer 5a.

[0031] First, the adhesive sheet 5 is attached to the magnet before being inserted into the magnet insertion hole 91. The rotor magnet 61 to which the adhesive sheet 5 is attached is inserted into the magnet insertion hole 91 of the rotor core. The rotor core 9 is heated in a state in which the magnet is inserted into the magnet insertion hole 91. By the heating of the rotor core 9, the adhesive sheet 5 foams and expands within the magnet insertion hole 91. That is, the adhesive sheet 5 after foaming presses the rotor magnet 61 in the radial direction within the magnet insertion hole 91. Thus, the rotor magnet 61 is positioned at a prescribed position within the magnet insertion hole 91.

[0032] Hereinafter, the processing of the adhesive sheet attaching device 1 will be described in the order of the cutting of the adhesive sheet 5, the attachment of the adhesive sheet 5, and the pressing of the adhesive sheet 5.

[0033] (Cutting of Adhesive Sheet 5)

[0034] Figure 2 FIG. 1 is a view showing an example of the cutting of the adhesive sheet 5 in the adhesive sheet attaching device 1 according to the embodiment. Figure 2 FIG. 2 is a view of the adhesive sheet attaching device 1 as viewed from the front.

[0035] As a portion that performs the cutting of the adhesive sheet 5, the adhesive sheet attaching device 1 has a supply roller 21, a first driven roller 22a, a second driven roller 22b, a third driven roller 22c, a fourth driven roller 22d, a winding roller 23, a leading end gripping portion 24, a label sheet pressing portion 25, a cutting portion 26, and an adhesive sheet attaching portion 27.

[0036] The supply roller 21, the label sheet pressing portion 25, the cutting portion 26, the adhesive sheet attaching portion 27, and the leading end gripping portion 24 are arranged in the left-right direction. The label sheet pressing portion 25, the cutting portion 26, and the adhesive sheet attaching portion 27 are located between the supply roller 21 and the leading end gripping portion 24 in the left-right direction. The cutting portion 26 is located between the label sheet pressing portion 25 and the adhesive sheet attaching portion 27 in the left-right direction.

[0037] The label sheet roll 51 is attached to the supply roller 21. The label sheet roll 51 is composed of a label sheet 52 wound in a roll shape. The label sheet 52 is a sheet in which the adhesive sheet 5 and a release sheet 53 are overlaid in the thickness direction. The adhesive layer 5a is located on one face of the adhesive sheet 5. The adhesive layer 5a is, for example, a layer to which an adhesive is applied. That is, the sheet in which the adhesive sheet 5 and the release sheet 53 are overlaid in the thickness direction is the label sheet 52 by attaching the release sheet 53 to the adhesive layer 5a. In the present embodiment, the release sheet 53 is located on the lower side of the label sheet 52 that is fed out. The adhesive sheet 5 is located on the upper side of the label sheet 52 that is fed out.

[0038] The front end of the release sheet 53 in the label sheet 52 is mounted on the winding roller 23. The winding roller 23 is rotated by a driving force of a winding motor, not shown. The winding roller 23 winds the release sheet 53. In addition, the label sheet 52 is pulled out from the supply roller 21 by the rotation of the winding roller 23.

[0039] The release sheet 53 contacts with the fixed stage 25a, the first driven roller 22a, the second driven roller 22b, the third driven roller 22c, and the fourth driven roller 22d in this order from the upstream side of the sheet conveyance direction of the label sheet 52. The release sheet 53 contacts with the upper side of the fixed stage 25a and the right side of the fixed stage 25a when the adhesive sheet attaching device 1 is viewed from the front.

[0040] In addition, the fixed stage 25a is a part of a label sheet pressing portion 25. The label sheet pressing portion 25 has the fixed stage 25a, a movable stage 25b, and a movable stage moving portion 25c. The movable stage moving portion 25c has a movable stage moving shaft 25d extending in the vertical direction. The fixed stage 25a is fixed to a frame or the like, not shown. The movable stage 25b is supported by the movable stage moving shaft 25d. Specifically, the lower end of the movable stage moving shaft 25d is connected to the upper surface of the movable stage 25b. The movable stage moving portion 25c moves the movable stage 25b and the movable stage moving shaft 25d in the vertical direction. In this way, the movable stage 25b can be moved in the direction approaching the fixed stage 25a and in the direction away from the fixed stage 25a. The movable stage moving portion 25c is, for example, an air cylinder. In addition, the movable stage moving portion 25c is not limited to the air cylinder, but can be a mechanism that moves the movable stage 25b using a motor, or a solenoid.

[0041] The label sheet 52 is fed in the horizontal direction from the supply roller 21 toward the fixed stage 25a. The label sheet 52 passes between the fixed stage 25a and the movable stage 25b. The release sheet 53 in the label sheet 52 is bent downward at the right end portion of the fixed stage 25a. The traveling direction of the release sheet 53 is bent by the first driven roller 22a toward the winding roller 23. The first driven roller 22a, the second driven roller 22b, the third driven roller 22c, and the fourth driven roller 22d contact with the release sheet 53 and guide the conveyance of the release sheet 53. As a result, the release sheet 53 is directed toward the winding roller 23. The winding roller 23 winds the release sheet 53.

[0042] The adhesive sheet 5 is linearly advanced without being bent at the fixed stage 25a. Therefore, the release sheet 53 is peeled from the label sheet 52 when passing through the fixed stage 25a. In other words, the adhesive sheet 5 and the release sheet 53 are separated in the thickness direction thereof. The adhesive sheet 5 separated from the label sheet 52 is advanced to the right when the adhesive sheet attaching device 1 is viewed from the front. In other words, the adhesive sheet 5 is advanced toward the cutting portion 26, the adhesive sheet attaching portion 27, and the front end gripping portion 24.

[0043] The front end gripping portion 24 grips the front end of the adhesive sheet 5. The front end gripping portion 24 has a main body portion 24a, a fixed claw 24b, and a movable claw 24c. The fixed claw 24b is fixed above the main body portion 24a. The movable claw 24c is installed on the main body portion 24a. The movable claw 24c is located below the fixed claw 24b. The movable claw 24c is movable in the up-and-down direction with respect to the fixed claw 24b by a driving force of a not-shown movable motor. In the case of gripping the adhesive sheet 5, the movable claw 24c is moved in a direction approaching the fixed claw 24b. The movable claw 24c and the fixed claw 24b sandwich the adhesive sheet 5 in the up-and-down direction. In the case of separating the adhesive sheet 5 from the front end gripping portion 24, the movable claw 24c is moved in a direction away from the fixed claw 24b.

[0044] The front end gripping portion 24 can also be provided with a not-shown front end gripping portion moving portion. The front end gripping portion moving portion moves the main body portion 24a, the fixed claw 24b, and the movable claw 24c in the left-and-right direction. For example, after the adhesive sheet 5 is cut out, the front end gripping portion moving portion can also move the main body portion 24a, the fixed claw 24b, and the movable claw 24c in a direction approaching the cutting portion 26. Thereby, the main body portion 24a, the fixed claw 24b, and the movable claw 24c are moved in order to grip the front end of the adhesive sheet 5. After the front end of the adhesive sheet 5 is gripped, when the label sheet 52 is fed out, the front end gripping portion moving portion can also move the main body portion 24a, the fixed claw 24b, and the movable claw 24c through below the adhesive sheet attaching portion 27 in a direction away from the cutting portion 26. For example, as viewed from above, the front end gripping portion moving portion moves the main body portion 24a, the fixed claw 24b, and the movable claw 24c to a position outside the adhesive sheet attaching portion 27. Thereby, the adhesive sheet 5 is located below the adhesive sheet attaching portion 27. The moving speed of the main body portion 24a, the fixed claw 24b, and the movable claw 24c can also be the same as the conveyance speed of the label sheet.

[0045] The cutting portion 26 is located below the adhesive sheet 5. The cutting portion 26 has a blade 26a and a blade moving portion 26b. The blade 26a has a cutting edge at an upper portion. The blade moving portion 26b moves the blade 26a in the up-and-down direction. That is, the blade moving portion 26b is movable in a direction approaching the adhesive sheet 5 and a direction away from the adhesive sheet 5 with respect to the blade 26a. The blade moving portion 26b is capable of moving the blade 26a upward until the upper end of the blade 26a is located above the adhesive sheet 5. In the case of cutting the adhesive sheet 5, the blade moving portion 26b moves the blade 26a above the adhesive sheet 5. In addition, the standby position of the blade 26a is below the adhesive sheet 5.

[0046] The adhesive sheet attaching section 27 has a holding section 27a and a first moving section 27b. The holding section 27a has, for example, a rectangular parallelepiped shape. The lower surface of the holding section 27a is horizontal. The first moving section 27b has a first moving shaft 27c extending in the up-and-down direction. The holding section 27a is supported by the first moving shaft 27c. Specifically, the upper surface of the holding section 27a is connected to the lower end of the first moving shaft 27c. The first moving section 27b moves the holding section 27a in the up-and-down direction. Thus, the holding section 27a can be moved in the direction approaching the adhesive sheet 5 and the direction away from the adhesive sheet 5. The first moving section 27b is, for example, an air cylinder. In addition, the first moving section 27b is not limited to an air cylinder, but can be a mechanism that moves the holding section 27a using a motor or a solenoid.

[0047] The holding section 27a has a plurality of suction holes 27d in the lower surface. In addition, the adhesive sheet attaching section 27 has a pipe 27e inside. The plurality of suction holes 27d are connected to the pipe 27e. A pressure reducing device 27f is connected to the pipe 27e. The pressure reducing device 27f is, for example, a pressure reducing pump. The adhesive sheet attaching section 27 sucks the adhesive sheet 5 by suction of the pressure reducing device 27f, and can hold the adhesive sheet 5. FIG. 1 shows a state in which the adhesive sheet attaching section 27 sucks the adhesive sheet 5. In addition, the adhesive sheet attaching section 27 can hold the adhesive sheet 5 by a method other than suction.

[0048] Next, an example of the cutting-out process of the adhesive sheet 5 will be described. First, the winding roller 23 rotates, and a label sheet 52 of a predetermined length is pulled out from the label sheet roll 51. The winding roller 23 winds the release sheet 53. Then, the winding roller 23 is stopped. The predetermined length is the length of one piece of the adhesive sheet 5 to be attached to the attachment target object 6.

[0049] On the other hand, the front end holding section 24 holds the front end of the adhesive sheet 5. In addition, the movable stage moving section 25c lowers the movable stage 25b. Thus, the fixed stage 25a and the movable stage 25b sandwich the adhesive sheet 5 in the thickness direction. Thus, both ends of the adhesive sheet 5 in the left-and-right direction are supported. That is, both ends of the adhesive sheet 5 in the conveying direction are supported. The front end holding section 24 and the label sheet pressing section 25 support the adhesive sheet 5 without slack.

[0050] The first moving section 27b moves the holding section 27a toward the adhesive sheet 5. The lower surface of the holding section 27a comes into contact with the upper surface of the adhesive sheet 5. The upper surface of the adhesive sheet 5 is the non-adhesive layer. Then, the suction of the adhesive sheet 5 by the pressure reducing device 27f is started. Next, the blade moving section 26b moves the cutting section 26 toward the adhesive sheet 5. Specifically, the blade moving section 26b moves the blade 26a upward. Thus, the cutting section 26 cuts the adhesive sheet 5. The cutting section 26 cuts the adhesive sheet 5 between the movable stage 25b and the adhesive sheet attaching section 27.

[0051] After the adhesive sheet 5 is cut, the blade moving section 26b moves the cutting section 26 to the lower side of the adhesive sheet 5. Then, the movable jaw 24c moves in a direction away from the fixed jaw 24b. As a result, the tip holding section 24 does not hold the adhesive sheet 5. Since the suction of the holding section 27a is continued, the cut adhesive sheet 5 does not fall from the holding section 27a. That is, the holding section 27a continues to hold the adhesive sheet 5. For example, the holding section 27a holds the adhesive sheet 5 horizontally. The holding section 27a can also hold the adhesive sheet 5 at a non-horizontal angle.

[0052] (Pasting of sheet)

[0053] Figure 3 and Figure 4 is a view showing an example of pasting of the adhesive sheet 5 according to the embodiment. Figure 3 and Figure 4 is a view of the adhesive sheet pasting apparatus 1 as viewed from the front. As a part of the pasting sheet, the adhesive sheet pasting apparatus 1 has an adhesive sheet pasting section 27, a supply section 3, and a pasting stage support section 33.

[0054] The supply section 3 has a pasting stage 31 and a feeder 32. The pasting stage 31 has a placement surface 31a on which the pasting object 6 is placed. The feeder 32 supplies the pasting object 6 to the pasting stage 31. In the example of Figure 3 In the example of, the upper surface of the pasting stage 31 is the placement surface 31a.

[0055] The adhesive sheet pasting section 27 has a second moving section 27g in addition to the holding section 27a and the first moving section 27b. The second moving section 27g is capable of moving the holding section 27a and the first moving section 27b connected to the holding section 27a. The second moving section 27g is, for example, a robot arm. The second moving section 27g can also be a mechanism including a rail, a motor, and a mechanism that causes the holding section 27a and the first moving section 27b to slide. The second moving section 27g moves the adhesive sheet pasting section 27 and the first moving section 27b to a position above the pasting object 6 placed on the placement surface 31a of the pasting stage 31. That is, the second moving section 27g moves the cut adhesive sheet 5 to a position above the pasting object 6 placed on the placement surface 31a of the pasting stage 31.

[0056] Next, an example of the sticking process of the adhesive sheet 5 will be described. When the second moving section 27g moves the adhesive sheet sticking section 27 above the sticking table 31, the sticking target object 6 is placed on the sticking table 31. The adhesive sheet sticking section 27 holds the cut adhesive sheet 5. Then, the adhesive sheet sticking section 27 ends the holding of the adhesive sheet 5. The adhesive sheet sticking section 27, for example, stops the suction based on the pressure reduction of the pressure reduction device 27f. As a result, the adhesive sheet 5 falls due to gravity. The adhesive sheet 5 starts to fall in a horizontal state. In this way, the adhesive sheet sticking section 27 holds the cut adhesive sheet 5 and sticks the cut adhesive sheet 5 to the sticking target object 6. The adhesive layer 5a of the adhesive sheet 5 is stuck to the sticking surface 6a of the sticking target object 6.

[0057] If the adhesive layer 5a of the adhesive sheet 5 contacts the sticking surface 6a of the sticking target object 6 in parallel or substantially in parallel, a large air bubble is sometimes generated between the adhesive sheet 5 and the sticking target object 6. The smaller the air bubble, the greater the adhesive strength of the adhesive sheet 5 and the sticking target object 6. In the present embodiment, in order to suppress the entry of the air bubble between the adhesive sheet 5 and the sticking target object 6, the sticking table support section 33 that supports the sticking table 31 on which the sticking target object 6 is placed has the following structure.

[0058] The sticking table support section 33 supports a part of the sticking table 31. Specifically, the sticking table support section 33 supports the part of the sticking table 31 at a position higher than the other part. In other words, the sticking table support section 33 supports the end portion of the upstream side of the sticking table 31 from below in the feeding direction of the sticking target object 6. The sticking table support section 33 positions the part of the placement surface 31a close to the adhesive sheet 5. The plane of the adhesive sheet 5 held by the adhesive sheet sticking section 27 is parallel to the horizontal direction. The sticking table support section 33 inclines the sticking table 31 with respect to the horizontal direction.

[0059] In this way, the adhesive sheet sticking device 1 sticks the adhesive sheet 5 having the adhesive layer 5a to the sticking target object 6. The adhesive sheet sticking device 1 includes the sticking table 31 having the placement surface 31a that feeds and places the sticking target object 6, the adhesive sheet sticking section 27 that sticks the adhesive layer 5a of the adhesive sheet 5 to the sticking target object 6 placed on the placement surface 31a, and the sticking table support section 33 that inclines the sticking table 31 by supporting a part of the sticking table 31 so that the part of the placement surface 31a is positioned closer to the adhesive sheet 5 than the other part.

[0060] Therefore, the object to be bonded 6 placed on the mounting surface 31a of the bonding table 31 is also tilted relative to the horizontal direction. Thus, the adhesive sheet 5 held by the holding portion 27a of the adhesive sheet bonding portion 27 initially contacts the portion of the object to be bonded 6 closest to the adhesive sheet bonding portion 27 on the mounting surface 31a of the bonding table 31. Then, the adhesive sheets 5 are sequentially placed on the object to be bonded 6, starting from the position closest to the adhesive sheet bonding portion 27. As a result, the adhesive sheet 5 expands the contact area with the object to be bonded 6 while expelling air between itself and the object to be bonded 6. Therefore, compared to the case where the adhesive sheet 5 is placed parallel to the surface of the object to be bonded 6, the amount of air entering between the object to be bonded 6 and the adhesive sheet 5 can be reduced. Thus, air bubbles can be suppressed from entering between the object to be bonded 6 and the adhesive sheet 5, making it difficult for the adhesive sheet 5 to peel off from the object to be bonded 6. Furthermore, the object to be bonded 6 can be supplied to the bonding table 31 using the feeder 32. Therefore, it is easy to attach the adhesive piece 5 to the object 6.

[0061] Furthermore, the adhesive sheet pasting device 1 includes a supply unit 3, which has a pasting table 31 and a feeder 32 for supplying the object to be pasted 6 to the pasting table 31. The feeder 32 has a replenishing surface 32a for placing the object to be pasted 6. The surface 31a of the pasting table 31 and the replenishing surface 32a are both inclined at the same angle relative to the horizontal direction. The pasting table 31 is connected to the downstream side of the object to be pasted 6 in the supply direction relative to the feeder 32.

[0062] Specifically, in Figure 3 In the example shown, the upper surface of the feeder 32 is a replenishment mounting surface 32a. One or more adhesive objects 6 can be mounted on the replenishment mounting surface 32a of the feeder 32. For example, an adhesive object 6 without an adhesive sheet 5 is mounted on the replenishment mounting surface 32a of the feeder 32. The adhesive table 31 is connected to the feeder 32. In this case, there are no steps in the vertical direction on both the mounting surface 31a of the adhesive table 31 and the replenishment mounting surface 32a of the feeder 32. That is, the mounting surface 31a of the adhesive table 31 and the replenishment mounting surface 32a of the feeder 32 form a flat plane.

[0063] Therefore, when the object to be pasted 6 is removed from the mounting surface 31a of the pasting table 31, the tilting of the replenishment mounting surface 32a of the feeder 32 allows the object to be pasted 6 placed on the replenishment mounting surface 32a of the feeder 32 to flow toward the mounting surface 31a of the pasting table 31. Thus, after the adhesive sheet 5 has finished pasting the object to be pasted 6, the next object to be pasted 6 can be supplied from the feeder 32 to the pasting table 31. Therefore, the adhesive sheet 5 can be continuously pasted onto multiple objects to be pasted 6.

[0064] Further, in the present embodiment, since the sticking table 31 is a structure different from the feeder 32, it is possible to only swing or move the sticking table 31. Thereby, it is possible to incline the sticking table 31 with respect to the horizontal direction. Thereby, as described above, it is possible to stick the adhesive sheet 5 to the sticking object 6 placed on the placement surface 31a of the sticking table 31 inclined with respect to the horizontal direction. Therefore, it is possible to easily realize the adhesive sheet sticking device 1 capable of suppressing the entry of bubbles between the sticking object 6 and the adhesive sheet 5.

[0065] The sticking table support portion 33 is an elastic member. For example, the elastic member is a compression spring. Thereby, since the sticking table support portion 32 supporting the sticking table 31 is an elastic member, in a case where the sticking table 31 is pressed from above by the pressing portion 7 described later, the inclination of the sticking table 31 changes. That is, the inclination of the sticking table 31 changes along the sticking jig 71 of the pressing portion 7 described later. Thereby, for the sticking object 6 placed on the placement surface 31a of the sticking table 31, it is possible to sequentially place the adhesive sheet 5 from the end portion thereof. Therefore, it is possible to easily realize the adhesive sheet sticking device 1 capable of suppressing the entry of bubbles between the sticking object 6 and the adhesive sheet 5.

[0066] Further, the sticking table 31 has a positioning portion 31b that determines the position of the supply direction of the sticking object 6 by the feeder 32 on the placement surface 31a. Thereby, the position of the sticking object 6 does not largely shift on the placement surface 31a of the sticking table 31. Thereby, it is possible to stick the adhesive sheet 5 to the determined position of the sticking object 6 placed on the placement surface 31a of the sticking table 31.

[0067] Specifically, the positioning portion 31b is provided to the end portion of the downstream side of the supply direction of the sticking object 6 in the sticking table 31. For example, the positioning portion 31b is a wall portion protruding upward from the placement surface 31a of the sticking table 31. The sticking object 6 supplied to the placement surface 31a of the sticking table 31 by the inclination of the supply placement surface 32a of the feeder 32 collides with the positioning portion 31b. The positioning portion 31b is located at the end point of the transport direction of the sticking object 6. In this way, the position of the sticking object 6 on the placement surface 31a of the sticking table 31 is determined. In addition, the structure that determines the position of the sticking object 6 on the placement surface 31a of the sticking table 31 is not limited to the above structure.

[0068] In the adhesive sheet sticking device 1, when the adhesive sheet 5 is stuck to the sticking object 6 placed on the placement surface 31a of the sticking table 31, the sticking table support portion 33 positions a part of the sticking table 31 closer to the adhesive sheet 5 than the other part. The sticking table support portion 33 supports a part of the sticking table 31 from below and lifts upward. The adhesive sheet sticking portion 27 places the adhesive sheet 5 from above on the sticking object 6 on the placement surface 31a.

[0069] When the adhesive sheet 5 is placed onto the object to be bonded 6 on the mounting surface 31a from above, the holding part 27a stops holding the adhesive sheet 5. For example, the decompression device 27f stops. For example, the horizontally held adhesive sheet 5 is pulled down towards the object to be bonded 6 by gravity. As a result, the adhesive layer 5a of the adhesive sheet 5 comes into contact with the object to be bonded 6. In this way, the adhesive sheet holding part 27a places the adhesive sheet 5 onto the object to be bonded 6 on the mounting surface 31a from above.

[0070] The result, such as Figure 4 As shown in the top section of the diagram, the end of the adhesive sheet 5 first contacts the object to be bonded 6. Specifically, the upstream end of the adhesive sheet 5 in the supply direction of the object to be bonded 6 contacts the object to be bonded 6. As the adhesive sheet 5 descends, the area of ​​the adhesive sheet 5 in contact with the object to be bonded 6 gradually widens. Figure 4 As shown in the middle and bottom sections of the diagram, the adhesive sheet 5 is sequentially attached to the object 6 from above the inclined surface (upstream side of the supply direction). As a result, the adhesive sheet 5 is attached to the object 6 while squeezing out the air between the object 6 and the adhesive sheet 5.

[0071] When the adhesive sheet 5 is applied to the object to be applied 6 placed on the mounting surface 31a of the application table 31, the application table support 33 supports the application table 31 from below. As a result, the mounting surface 31a of the application table 31 and the object to be applied 6 placed on the mounting surface 31a of the application table 31 are inclined relative to the horizontal direction. Therefore, the adhesive sheet 5 held by the holding portion 27a of the adhesive sheet application portion 27 contacts the portion of the object to be applied 6 closest to the adhesive sheet application portion 27 first. Then, the adhesive sheets 5 are placed sequentially on the object to be applied 6, starting from the position closest to the adhesive sheet application portion 27. The adhesive sheet 5 expands the contact area with the object to be applied 6 while squeezing out the air between itself and the object to be applied 6. Therefore, compared to the case where the adhesive sheet 5 is placed parallel to the surface of the object to be applied 6, the amount of air entering between the object to be applied 6 and the adhesive sheet 5 can be reduced. This prevents air bubbles from entering between the object to be pasted 6 and the adhesive sheet 5, making it difficult for the adhesive sheet 5 to peel off from the object to be pasted 6.

[0072] To reliably ensure that the ends of the sheet make contact first, such as Figure 3As shown, when the adhesive sheet 5 is placed from above with respect to the adherend 6, the position at which the end of the adhesive sheet 5 is closest to the adherend 6 can also be a position overlapping the adhering stage support portion 33 when the adhesive sheet 5 is viewed from above or a position further outside than the adhesive sheet 5. Thus, the end of the adhesive sheet 5 first comes into contact with the adherend 6. That is, the adhesive sheet 5 is adhered to the adherend 6 from the end of the adhesive sheet 5. The adhesive sheet 5 is adhered to the adherend 6 while expelling air between the adhesive sheet 5 and the adherend 6. Thus, the adhesive sheet 5 can be adhered to the adherend 6 while reducing air bubbles.

[0073] (Pressing of sheet)

[0074] Figure 5 and Figure 6 is a view showing an example of pressing of the adhesive sheet 5 according to the embodiment. Figure 5 and Figure 6 shows an example of the adhering stage 31 of the adhesive sheet adhering apparatus 1 viewed from the right side. Figure 7 shows an example of the adhering stage 31 according to the embodiment when the adhesive sheet adhering apparatus 1 is viewed from the front side and the adhesive sheet 5 is pressed.

[0075] As a portion for pressing the sheet, the adhesive sheet adhering apparatus 1 has an adhering stage moving portion 4 and a pressing portion 7. For example, the pressing portion 7 is located in front of the adhesive sheet adhering portion 27. In addition, the position of the pressing portion 7 is not limited to the front of the adhesive sheet adhering portion 27.

[0076] The adhering stage 31 in the supply portion 3 is movable in the front-rear direction by the adhering stage moving portion 4. In other words, the adhering stage moving portion 4 is capable of moving the adhering stage 31 from an adhering position at which the adhesive sheet 5 is adhered to the adhering stage 31 to a pressing position at which the adhesive sheet 5 is pressed. In addition, the adhering stage moving portion 4 is capable of moving the adhering stage 31 from the pressing position to the adhering position.

[0077] For example, the adhering stage moving portion 4 has a slide rail 41 and a slide moving motor not shown. In the case of moving the adhering stage 31, the slide moving motor is rotated. When the slide moving motor is rotated, the adhering stage 31 is moved along the slide rail 41. The adhering stage moving portion 4 moves the adhering stage 31 to the pressing position. By moving to the pressing position, the adhering stage 31 is separated from the feeder 32. After the pressing of the adhesive sheet 5 is completed, the adhering stage moving portion 4 returns the adhering stage 31 to the adhering position. By moving the adhering stage 31 to the adhering position, the adhering stage 31 is connected to the feeder 32.

[0078] The pressing part 7 has an adhesive clamp 71. The adhesive clamp 71 presses the adhesive sheet 5, which is placed on the object to be adhered to 6 via the adhesive sheet adhesive part 27, onto the object to be adhered to 6. By pressing the adhesive sheet 5 adhered to the object to be adhered to 6 by the adhesive clamp 71 of the pressing part 7, air bubbles between the adhesive sheet 5 and the object to be adhered to 6 are squeezed out. As a result, air bubbles between the adhesive sheet 5 and the object to be adhered to 6 can be further reduced. This makes it difficult to peel the adhesive sheet 5 off the object to be adhered to 6.

[0079] Specifically, the pressing part 7 includes an adhesive clamp 71 and an adhesive clamp moving part 72. The adhesive clamp moving part 72 has an adhesive clamp moving shaft 73 extending in the vertical direction. The adhesive clamp 71 is supported by the adhesive clamp moving shaft 73. Specifically, the lower end of the adhesive clamp moving shaft 73 is connected to the upper surface of the adhesive clamp 71. The adhesive clamp moving part 72 moves the adhesive clamp 71 and the adhesive clamp moving shaft 73 in the vertical direction. Thus, the adhesive clamp 71 can move towards the adhesive table 31 and the adhesive sheet 5 and away from the adhesive table 31 and the adhesive sheet 5. The adhesive clamp moving part 72 is, for example, a cylinder. In addition, the adhesive clamp moving part 72 is not limited to a cylinder; it can also be a mechanism that uses an electric motor to move the adhesive clamp 71, or it can be a solenoid. The adhesive clamp 71 presses the adhesive sheet 5 downward.

[0080] Next, use Figure 5 to Figure 7 Here is an example illustrating the process of pressing and bonding sheet 5. Figure 5 and Figure 7 The left figure shows an example of the position of the adhesive clamp 71 and the adhesive clamp moving axis 73 before pressing. The adhesive clamp 71 moves downward by means of the adhesive clamp moving part 72. Figure 6 and Figure 7 The right figure shows an example of the state in which the adhesive clamp 71 presses down on the adhesive piece 5.

[0081] Here, as Figure 5 to Figure 7 As shown, the surface of the adhesive clamp 71 that contacts the adhesive sheet 5 is a curved surface 71a that protrudes in the direction of pressing the object 6 to be adhered. This allows the convex portion of the curved surface 71a to be pressed onto the adhesive sheet 5. As a result, air bubbles in and around the portion of the adhesive sheet 5 that contacts the clamp are squeezed out of the adhesive sheet 5.

[0082] For example, the four corners of the lower surface of the adhesive clamp 71 can be chamfered. The lower surface of the adhesive clamp 71 can also be a curved surface 71a based on the chamfering treatment. The adhesive clamp 71 can also be a U-shaped shape that bulges downward when viewed from the right or left of the adhesive patch adhesive device 1. In addition, the adhesive clamp 71 can also be a U-shaped shape that bulges downward when viewed from the front or rear of the adhesive patch adhesive device 1.

[0083] Further, the adhesive jig 71 has an elastic portion 71b in a portion that contacts the adhesive sheet 5. The elastic portion 71b covers the entire lower surface of the adhesive jig 71. In other words, the elastic portion 71b is attached to the lower surface of the adhesive jig 71. For example, the elastic portion 71b is made of urethane rubber. Alternatively, the elastic portion 71b can be made of a material other than urethane rubber. The elastic portion 71b of the adhesive jig 71 is deformed by contact with the adhesive sheet 5, and uniformly applies pressure to the adhesive sheet 5. That is, when the adhesive jig 71 is pressed against the adhesive sheet 5, the range of the adhesive sheet 5 pressed by the adhesive jig 71 gradually expands. Thus, air bubbles between the adhesive sheet 5 and the adherend 6 can be pushed out from the center to the periphery of the adhesive jig 71.

[0084] In the adhesive sheet adhesive device 1, the position at which the front end of the curved surface 71a of the adhesive jig 71 contacts the adhesive sheet 5, as viewed from the direction in which the jig presses the adhesive sheet 5, can also be the center of the adhesive sheet 5 placed on the adherend 6. Here, the center of the adhesive sheet 5 refers to the geometric center of the adhesive sheet 5 as viewed from above. The center of the adhesive sheet 5 can also be offset from the geometric center of the adhesive sheet 5. For example, the front end of the curved surface 71a of the adhesive jig 71 can press a position that is offset from the center by several mm or so. Thus, the front end of the curved surface 71a of the adhesive jig 71 can be pressed against the center of the adhesive sheet 5. Thus, air bubbles near the center of the adhesive sheet 5 can also be pushed out to the outside of the adhesive sheet 5.

[0085] Further, the portion of the adhesive jig 71 that contacts the adhesive sheet 5 can overlap the adhesive sheet 5, as viewed from the direction in which the jig presses the adhesive sheet 5. That is, the adhesive jig 71 can press the entire face of the adhesive sheet 5. The adhesive sheet 5 can be pressed using the adhesive jig 71. By pressing the adhesive sheet 5 using the adhesive jig 71, air bubbles between the adhesive sheet 5 and the adherend 6 are pushed out to the outside of the adhesive sheet 5.

[0086] Here, the adhesive stage support portion 33 is an elastic member. Thus, when a force is applied to the adhesive stage 31, the inclination of the adhesive stage 31 changes. When the adhesive jig 71 presses the adhesive sheet 5, the inclination of the adhesive stage 31 gradually changes due to the pressing force. As the pressing proceeds, the angle of the placement surface 31a of the adhesive stage 31 with respect to the horizontal direction becomes parallel or substantially parallel to the lower surface of the adhesive jig 71.

[0087] Figure 7 An example of the change in the inclination angle of the adhesive stage 31 with respect to the horizontal direction is shown in FIG. 8. As shown in FIG. 8, the inclination angle of the adhesive stage 31 with respect to the horizontal direction gradually decreases as the adhesive jig 71 presses the adhesive sheet 5. As the pressing proceeds, the angle of the placement surface 31a of the adhesive stage 31 with respect to the horizontal direction becomes parallel or substantially parallel to the lower surface of the adhesive jig 71. Figure 7As shown, the sticking jig 71 presses the adhesive sheet 5 until the lower surface of the sticking jig 71 is in close contact with the entire adhesive sheet 5. As the pressing proceeds, the elastic portion 71b is flattened. As a result, the lower surface of the sticking jig 71 becomes horizontal or substantially horizontal. Therefore, the placement surface 31a of the sticking table 31 also becomes horizontal or substantially horizontal. The lower surface of the sticking jig 71 is in close contact with the entire adhesive sheet 5. Thus, the entire adhesive sheet 5 can be pressed, and a large number of air bubbles present between the adhesive sheet 5 and the sticking object 6 can be squeezed out.

[0088] After the adhesive sheet 5 is pressed, the sticking jig moving portion 72 moves the sticking jig 71 upward. Thus, the sticking jig 71 is not in contact with the adhesive sheet 5. With the upward movement of the sticking jig 71, the sticking of the sticking object 6 to the adhesive sheet 5 is completed. The adhesive sheet sticking device 1 can also be provided with a sticking finished product moving portion that moves the sticking finished product, i.e., the sticking object 6 to which the adhesive sheet 5 is stuck, from the sticking table 31. For example, the sticking finished product moving portion can also be a robot arm. Alternatively, the sticking finished product moving portion can be a pin that pushes out the sticking finished product from the sticking table 31 toward a storage portion for the sticking finished product.

[0089] Then, the sticking table moving portion 4 moves the position of the sticking table 31 to the sticking position. When returning to the sticking position, the sticking table 31 is connected to the feeder 32. When the sticking table 31 is connected to the feeder 32, a new sticking object 6 can also be supplied from the feeder 32 to the sticking table 31 in the absence of the sticking object 6.

[0090] In the case where the sticking of the adhesive sheet 5 to the sticking object 6 is repeated, the cutting of the adhesive sheet 5, the sticking of the adhesive sheet 5, the movement of the sticking table 31 to the pressing position, the pressing of the adhesive sheet 5, the movement of the sticking table 31 to the sticking position, and the supply of the sticking object 6 to the sticking table 31 are repeated.

[0091] (Other Embodiments)

[0092] The above describes embodiments of the present application, but the above-described embodiments are merely examples for implementing the present application. Therefore, the above-described embodiments are not limited to the above-described embodiments, and can be appropriately modified within the scope of the gist of the present application.

[0093] In the above-described embodiments, an example is described in which, after the holding portion 27a of the adhesive sheet sticking portion 27 is moved above the sticking table 31, the suction based on the decompression device 27f is stopped, and the holding of the cut adhesive sheet 5 is ended, thereby sticking the cut adhesive sheet 5 to the sticking object 6. However, the holding portion 27a of the adhesive sheet sticking portion 27 can end the holding of the adhesive sheet 5 after the first moving portion 27b moves the holding portion 27a in a direction approaching the sticking object 6 so that the adhesive sheet 5 comes into contact with the sticking object 6.

[0094] Further, the first moving section 27b of the adhesive sheet attaching section 27 can also move the holding section 27a of the adhesive sheet attaching section 27 toward the attaching object 6 until the entire adhesive sheet 5 held by the holding section 27a of the adhesive sheet attaching section 27 is attached to the attaching object 6. After the entire adhesive sheet 5 held by the holding section 27a of the adhesive sheet attaching section 27 is attached to the attaching object 6, the holding section 27a of the adhesive sheet attaching section 27 can also end the holding of the adhesive sheet 5. At this time, the holding section 27a of the adhesive sheet attaching section 27 presses the adhesive sheet 5 against the attaching object 6. Thereby, when the adhesive sheet 5 is attached, it is possible to squeeze out the air bubbles between the adhesive sheet 5 and the attaching object 6.

[0095] In the case where the holding section 27a of the adhesive sheet attaching section 27 presses the adhesive sheet 5 against the attaching object 6, the attaching table support section 33 that supports the attaching table 31 is an elastic member. Therefore, in the case where the attaching table 31 is pressed from above by the holding section 27a of the adhesive sheet attaching section 27, the inclination of the attaching table 31 changes in the same manner as Figure 7 In the same manner as the structure in which the attaching jig 71 presses the adhesive sheet 5 as shown in FIG. 6, the inclination of the attaching table 31 changes. That is, the inclination of the attaching table 31 changes along the lower surface of the holding section 27a of the adhesive sheet attaching section 27. Thereby, it is possible to squeeze out the air bubbles between the adhesive sheet 5 and the attaching object 6.

[0096] The surface of the holding section 27a of the adhesive sheet attaching section 27 that contacts the adhesive sheet 5 can also be a curved surface that protrudes toward the direction in which the attaching object 6 is pressed. Further, the portion of the holding section 27a of the adhesive sheet attaching section 27 that contacts the adhesive sheet 5 can also be composed of urethane rubber. Alternatively, the portion of the holding section 27a that contacts the adhesive sheet 5 can also be composed of an elastic material other than urethane rubber. Further, for example, the elastic material of the holding section 27a can also cover the entire lower surface of the holding section 27a.

[0097] In the embodiment described above, the adhesive sheet attaching apparatus 1 is provided with the supply section 3 that has the attaching table 31 and the feeder 32 that supplies the attaching object 6 to the attaching table 31. However, the adhesive sheet attaching apparatus 1 can also be provided with a robot that supplies the attaching object 6 to the attaching table 31.
