Description

The present invention relates to a tape peeling method and a tape peeling device, and more particularly to a technique for reliably and cleanly peeling a ring-shaped tape attached to a thin plate ring-shaped frame.

In the field of electronic device manufacturing technology, a frame (or panel) that constitutes an electronic device is mounted on a surface portion of a frame on which electronic components are mounted so as to prevent foreign matter such as scratches and dust from being attached when the frame is loaded and stored. A protective tape is attached. Then, when the frame is used, after removing the tape attached from the frame, the frame is cleaned thoroughly.

Conventionally, the peeling of the tape from the frame relies on manual work capable of peeling reliably and cleanly. However, in a production line of an electronic device, the manual peeling of the tape impedes complete automation of the production line.

As a peeling device for mechanically peeling a tape or sheet, there are Patent Document 1 and Patent Document 2, for example.

The protective tape peeling device of Patent Document 1 attaches peeling adhesive tapes from the non-adhesive surface side to a protective tape attached to the surface of a semiconductor wafer held via a supporting adhesive tape of a ring-shaped frame. Stick by pressing with a member. Then, by peeling the peeling adhesive tapes, the protective tape is integrally peeled from the surface of the semiconductor wafer together with the peeling adhesive tapes.

The sheet peeling device of Patent Document 2 applies an adhesive to either the peeling sheet or the adhesive sheet of the adherend having the adhesive sheet stuck to the surface thereof, and bonds the peeling sheet to the adhesive sheet. The peeling sheet and the adherend are moved relative to each other, whereby the adhesive sheet is peeled from the adherend together with the peeling sheet.

As described above, the tape peeling devices of Patent Document 1 and Patent Document 2 attach a peeling tape to a tape to be peeled and peel the tape together, and the technical idea is the same.

Then, the adherend W to which the tape peeling is incomplete is removed from the above-mentioned transport line 24.

The cleaning station 18 has a pressurized water cleaning device 30 (see FIG. 8) for cleaning the back surface of the adherend W, and cleans the back surface of the adherend W after tape peeling. The pressurized water cleaning device 30 will be described in detail later.

In the drying station 20, the adherend W after the back surface cleaning is dried. Any drying method may be used as long as it does not adversely affect the quality of the adherend W, but hot air drying can be preferably used, for example.

The storage station 22 receives the dried adherends W one by one and stores them in a rack (not shown). As a storage means for the adherend W, a recovery robot (not shown) similar to the supply robot 26 can be used. That is, the recovery robot adsorbs the adherends W, which have been conveyed to the end point of the conveyance line 24, to the suction cups one by one and conveys them to the storage station 22 and stores them in the rack.

The transport line 24 only needs to be capable of continuously transporting the adherend W, and does not mean that the transport system of each station is the same.
Next, the tape peeling device 28 according to the embodiment of the present invention incorporated in the tape peeling station 14 will be described.

A tape T (for example, a protective tape) is attached so as to have a shape. 2, arrows indicate the direction in which pasting target body W is transferred, W _A denotes the side of the pasting target body W as seen from the conveying direction.

As the adherend W made of a material that can be attracted to the magnet, for example, ferritic stainless steel or martensitic stainless steel (JIS 400 series) can be used.

[Tape peeling device]
FIG. 3 is a side view illustrating the overall configuration of the tape peeling device 28 according to the embodiment of the present invention, and FIG. 4 is a perspective view of a main part.

As shown in FIGS. 3 and 4, the tape peeling device 28 according to the present embodiment mainly includes a tape peeling unit 32 that blows pressurized water onto the tape T of the adherend W to separate the tape T from the adherend W. And an adherend conveying means 34 that carries in the adherend W before tape peeling to the tape peeling section 32 and carries out the adherend W after tape peeling from the tape peeling section 32, and the tape peeling device 28. And a control means 35 (see FIG. 3) for controlling the.

The tape peeling section 32 and the adherend conveying means 34 are provided on the device frame 36. Further, in the present embodiment, an example in which the control means 35 for controlling the entire tape peeling/cleaning line 10 also controls the tape peeling device 28 will be described, but a dedicated control means for the tape peeling device 28 may be provided.

3 and 4, the conveyance direction of the adherend W by the adherend conveyance means 34 is the Y-axis direction, the direction orthogonal to the Y-axis direction on the horizontal plane is the X-axis direction, and the tape peeling device 28 is shown. The height direction will be described as the Z-axis direction.

(Transfer means for adherend)
The adherend conveying means 34 is a long plate mainly made of a material that is hard to be attracted to a magnet and arranged in the horizontal direction. The adherend W is placed and the tape peeling section 32 is a plate. And the width of the adherend with respect to the width direction (X-axis direction) of the placing plate 38 when the adherend W is placed on the placing plate 38. The positioning means 40 for positioning in the direction (X-axis direction), and the back surface of the adherend W placed on the placing plate 38, which is disposed below the placing plate 38, via the placing plate 38. A magnet means 42 for adsorbing and desorbing the magnet plate 42, a reciprocating means 44 arranged below the mounting plate 38 for reciprocating the magnet means 42 in the longitudinal direction (Y-axis direction) of the mounting plate 38, A delivery means 45 for delivering the adherend W from the delivery position which is the end point position of the mounting plate 38 to the inspection station 16.

In addition, it is preferable that the tape peeling portion 32 is provided at a position substantially at the center of the mounting plate 38 in the longitudinal direction. Further, the control means 35 controls the timing of attraction and desorption of the magnet means 42 and the reciprocating timing of the reciprocating means 44.

As shown in FIGS. 3 and 4, the mounting plate 38 is formed of a long rectangular plate horizontally arranged with a material that is hard to be attracted to the magnets. The mounting plate 38 has an upper side and a lower side. There is no passage of liquid such as water between them. The mounting plate 38 is supported at its four corners by four columns 37, 37... Standing on the floor surface 36A of the apparatus frame 36.
For example, austenitic stainless steel (JIS300 series) can be used as the mounting plate 38 made of a material that does not easily attract to the magnet (including a case where it does not attract at all).

Then, with the back surface of the adherend W placed on the placing plate 38 being attracted by the magnet means 42 via the placing plate 38, the reciprocating means 44 moves the magnet means 42 onto the adherend W. The placement plate 38 is moved in the longitudinal direction (Y-axis direction), which is the transport direction. As a result, the adherend W moves in the Y-axis direction so as to slide on the mounting plate 38 as the magnet means 42 moves, so that the adherend W can be carried into the tape peeling section 32, It can be carried out from the tape peeling section 32.

As described above, the adherend transfer means 34 according to the present invention is a transfer system that moves the adherend W by sliding the adherend W on the mounting plate 38. A large number of hemispherical minute projections 46, 46... Are formed on the upper surface (the surface on which the adherend W is placed). As a result, the contact area between the back surface of the adherend W and the upper surface of the mounting plate 38 is reduced, and sliding friction can be reduced, so that the adherend W can be transported smoothly.

The size (diameter of the hemisphere) of the hemispherical minute projections 46 formed on the upper surface of the mounting plate 38 is such that the sliding friction of the adherend W can be reduced, and the adherend W is magnetized by the magnet means 42. It is preferable to design so as to satisfy the conditions that it can be adsorbed through the mounting plate 38 and that water is unlikely to collect on the upper surface of the mounting plate 38. For example, a diameter of 10 to 20 mm is suitable.

The adherend W placed on the mounting plate 38 is positioned by the positioning means 40 in the width direction (X-axis direction) of the adherend W with respect to the width direction (X-axis direction) of the mounting plate 38. Be seen. The reason for performing the positioning will be described in the tape peeling unit 32 described later.

As shown in FIGS. 3 and 4, the positioning means 40 includes a belt conveyor 48 which mainly carrying the pasting target body W, both sides W _A of pasting target body W conveyed by the belt conveyor _48, W _A ( 2) and a plurality of guide rollers 50, 50... Which rotate in contact with each other, and a vertically moving means 52 for vertically moving the belt conveyor 48. The belt conveyor 48 and the guide rollers 50 are provided on a support frame 54 provided inside the device frame 36, and the support frame 54 is supported by the vertical movement means 52 provided upright on the bottom 36A of the device frame 36.

The belt conveyor 48 has a pair of endless belts 56, 56 on both sides of the mounting plate 38 that run in parallel in the Y-axis direction. The pair of endless belts 56, 56 is stretched over a plurality of transport rollers 58 rotatably supported by the support frame 54. As a result, a belt conveyor 48 having a conveying portion parallel to the placing plate 38 is formed. Then, one of the plurality of transport rollers 58 is rotationally driven to rotate the pair of endless belts 56, 56 and transport the adherend W. The drive of the belt conveyor 48 is controlled by the control means 35.

A plurality of guide rollers 50 are disposed at regular intervals in the Y-axis direction on both sides of the belt conveyor 48, both sides W _A of pasting target body W conveyed by the belt conveyor _48, rotates in contact with the W _A. This guides the conveyance of the adherend W and positions the adherend W in the width direction with respect to the width direction of the placing plate 38 that is the conveyance destination.

The vertical movement unit 52 vertically moves the support frame 54 provided with the belt conveyor 48 and the guide roller 50. The standby position where the belt conveyor 48 is located above the placement plate 38 and the delivery position of the adherend W where the height of the pair of endless belts 56, 56 and the placement plate 38 are the same. Move up and down between. As the vertically moving means 52, for example, a cylinder device as shown in FIG. 3 can be used. The vertical movement means 52 is controlled by the control means 35. Accordingly, the adherend W can be transferred from the belt conveyor 48 to the placing plate 38 in a state where the adherend W is positioned in the width direction with respect to the widthwise direction of the placing plate 38.

FIG. 5 is a perspective view for explaining the magnet means 42 of the adherend transfer means 34.
As shown in FIG. 5, the magnet means 42 mainly includes a plate-shaped magnet holding plate 60 provided below the mounting plate 38 and having a surface parallel to the surface of the mounting plate 38, and a magnet holding plate. The plurality of permanent magnets 62, 62... (4 in FIG. 5) arranged on the mounting plate 38 side of 60 and the magnet holding plate 60 are moved up and down to be attached to the mounting plate 38. An elevating means 64 for adsorbing and desorbing the back surface of the body W via the mounting plate 38.

As shown in FIG. 5, the permanent magnets 62, 62... Are fixed to the projecting plates 60A, 60A... That are projected from the four corners of the rectangular magnet holding plate 60 in the X-axis direction, and a total of four permanent magnets are fixed.

The attraction surfaces 62A of the four permanent magnets 62 are formed to be flush with each other, and the attraction surfaces 62A of the four permanent magnets 62 are slightly (for example, about 1 to 2 mm) from the upper surface 60B of the magnet holding plate 60. It is preferable to make it protrude. As a result, the attraction surfaces 62A of the four permanent magnets 62 evenly contact the back surface of the mounting plate 38, and when the magnet means 42 is moved in the longitudinal direction (Y-axis direction) of the mounting plate 38, The upper surface 60B of the magnet holding plate 60 does not rub against the lower surface of the mounting plate 38. Therefore, the magnet means 42 can be smoothly moved with respect to the mounting plate 38.

In addition, in the present embodiment, the permanent magnets 62 are provided at the four corners of the magnet holding plate 60, but the arrangement position and the number of the permanent magnets 62 are not particularly limited. The point is that the back surface of the adherend W placed on the placing plate 38 can be surely adsorbed via the placing plate 38.

Further, a total of four auxiliary rollers 68 rotatably supported in the Y-axis direction are provided between the overhanging plates 60A at the four corners of the magnet holding plate 60 between the Y-axis directions. That is, two auxiliary rollers 68 are provided on each side of the magnet holding plate 60 in the width direction (X-axis direction).

Accordingly, when the back surface of the adherend W placed on the placing plate 38 is attracted via the placing plate 38, the four auxiliary magnets 68 are placed together with the four permanent magnets 62. It contacts the back surface of the plate 38. Then, when the magnet means 42 is moved in the longitudinal direction (Y-axis direction) of the mounting plate 38, the auxiliary roller 68 rotates the back surface of the mounting plate 38 in the longitudinal direction (Y-axis direction) of the mounting plate 38. Since the vehicle travels, the magnet means 42 can be moved more smoothly.

In this embodiment, a total of four auxiliary rollers 68 are provided, but the arrangement position and the number of auxiliary rollers 68 are not particularly limited. The point is that the auxiliary roller 68 can smoothly move the magnet means 42.

Further, as shown in FIG. 5, as the elevating means 64, any means can be used as long as it can bring the magnet holding plate 60 into and out (approach and separate) from the mounting plate 38. A cylinder device in which the piston rod 64A expands and contracts in the Z-axis direction as in the form can be preferably used.

When a cylinder device is used as the elevating means 64, it is preferable that the tip end of the piston rod 64A and the magnet holding plate 60 are connected by a spherical joint 70. As a result, the magnet holding plate 60 can be swingably supported on the tip of the piston rod 64A. Therefore, even if the expansion and contraction direction of the piston rod 64A is not completely orthogonal to the mounting plate 38, when the magnet holding plate 60 is raised to bring the permanent magnet 62 into contact with the back surface of the mounting plate 38. The magnet holding plate 60 swings along the direction of the back surface of the mounting plate 38. As a result, the four permanent magnets 62 can be surely brought into contact with the back surface of the mounting plate 38, so that the adherend W mounted on the mounting plate 38 can be reliably contacted by the four permanent magnets 62. And it can be adsorbed uniformly.

The reciprocating means 44 may be any means as long as it can accurately reciprocate the magnet means 42 in the longitudinal direction (Y-axis direction) of the mounting plate 38, but as in the present embodiment, a reciprocating means of ball screw type. Can be preferably used.

As shown in FIGS. 3 and 4, the ball screw type reciprocating means 44 mainly includes a ball screw 72, a servomotor 74 that rotates the ball screw 72 forward and backward, a nut member 76 that is screwed into the ball screw 72, and a nut member. 76 and a rail 78 that is slidably supported.

That is, a long base 80 parallel to the mounting plate 38 (parallel to the Y-axis direction) is provided on the floor surface 36A of the device frame 36 below the mounting plate 38. A rail 78 is laid in the Y-axis direction on the base 80, and a nut member 76 is slidably supported on the rail 78 via a linear guide 82. Further, the nut member 76 is provided with a mounting base 84 on which the elevating means 64 of the magnet means 42 is mounted. A ball screw 72 arranged in the Y-axis direction is screwed into the nut member 76, and both ends of the ball screw 72 are supported by a pair of bearings 86, 86 arranged at both ends of the base 80. Further, one end of the ball screw 72 penetrates one bearing 86 and is connected to a servo motor 74 fixedly mounted on the base 80.

As a result, the nut member 76 reciprocates on the rail 78 by the forward and reverse rotations of the servomotor 74, so that the magnet means 42 mounted on the nut member 76 via the mounting base 84 reciprocates in the Y-axis direction. Therefore, the adherend W is attached to the tape peeling portion 32 while the back surface of the adherend W placed on the mount plate 38 is attracted by the four permanent magnets 62 of the magnet means 42 via the mount plate 38. It can be carried in and out.

The transport speed for transporting the adherend W on the mounting plate 38 is preferably in the range of 10 to 30 m/min in consideration of efficiency of tape peeling and conveyance accuracy of the adherend W. Here, the conveyance accuracy means that the adherend W can be conveyed in a state where there is no attraction deviation between the adherend W and the permanent magnet 62 during the conveyance.

The number of the magnet means 42 mounted on the mounting table 84 may be one, but as the long mounting table 84 which is long in the longitudinal direction (Y-axis direction) of the mounting plate 38, the magnet means 42 is provided at both ends in the longitudinal direction. It is preferable to provide 42 (42A, 42B). That is, by the reciprocating operation of the nut member 76, the carrying-in magnet means 42A that reciprocates between the tape peeling portion 32 and the transfer position where the adherend W is transferred from the positioning means 40 to the mounting plate 38, and the tape peeling portion. It is preferable to provide two of the carrying-out magnet means 42B that reciprocates between 32 and the position of the end of the mounting plate 38. Thereby, since the adherend W can be carried in and out of the tape peeling section 32 at the same time, the tape peeling tact time can be shortened.

The feeding means 45 is formed in the same structure except that the guide roller 50 is removed from the positioning means 40 described above. That is, the pair of parallel endless belts 56, 56 is stretched over the plurality of transport rollers 58 to form the belt conveyor 48, and the belt conveyor 48 is supported by the support frame 54. Then, the support frame 54 is moved up and down by the up-and-down moving means 52 to raise the belt conveyor 48 located below the placing plate 38 to the height of the placing plate 38, and the object placed on the placing plate 38 is lifted. The pair of endless belts 56 scoop and receive the both ends of the adherend W. Then, the adherend W received is conveyed to the inspection station 16.

The delivery means 45 is not limited to the above structure, and it is sufficient that the adherend W can be delivered from the tape peeling station 14 to the inspection station 16.

(Tape peeling part)
As shown in FIGS. 3 and 4, the tape peeling section 32 mainly prevents the pressurized water jet gun 88 for jetting the pressurized water, the splash of the pressurized water jetted from the pressurized water jet gun 88, and the loading of the adherend W. A chamber 94 having an opening 90 and a carry-out port 92 and having the mounting plate 38 as a bottom surface, and a tape provided below the chamber 94 and communicating with the chamber 94, the tape peeled from the adherend W is ejected under pressure. And a tape collecting means 96 (see FIG. 7) for collecting together with the pressurized water jetted from the gun 88.

3 and 4, the tape collecting means 96 is omitted for the sake of clarity, and FIG. 7 shows the tape collecting means 96. 6 shows the details of the pressurized water jet gun 88.

The chamber 94 is formed in a rectangular tube shape with an upper surface and a lower surface opened, and a U-shaped cutout is formed in a lower front portion into which the adherend W is loaded and a lower rear portion from which it is unloaded. Then, the lower surface opening of the chamber 94 is closed at the central portion of the mounting plate 38 in the longitudinal direction. As a result, a box-shaped chamber 94 having an open upper surface is formed, and a carry-in port 90 and a carry-out port 92 for the adherend W are formed. A nozzle head 98 (see FIG. 6) of the pressurized water jet gun 88 is provided inside the chamber 94 to prevent the pressurized water jetted from the pressurized water jet gun 88 from being scattered by the chamber 94.

It is preferable to provide shutters (not shown) that move up and down and open and close at the carry-in port 90 and the carry-out port 92 of the adherend W in the chamber 94. As the shutter driving means, for example, a cylinder device can be used. The drive of the shutter is controlled by the control means 35. That is, the shutter is opened at the time of loading and unloading the adherend W to the tape peeling section 32, and the pressurized water is ejected from the pressurized water ejection gun 88 to close the shutter at the time of tape peeling of the adherend W. As a result, the splash of the pressurized water ejected from the pressurized water ejection gun 88 can be more reliably prevented.

The pressurized water jet gun 88 is supported by an XY moving mechanism 100 that is movable in the longitudinal direction (Y-axis direction) and the width direction (X-axis direction) of the mounting plate 38. That is, the Y-axis actuator 104 and the Y-axis rail 106 are fixed to the pair of upper beams 102 and 102 that are parallel to the Y-axis direction of the device frame 36, and the X-axis actuator straddles the Y-axis actuator 104 and the Y-axis rail 106. 108 is slidably supported. As a result, the XY moving mechanism 100 is formed.

The slider 110 is slidably supported by the X-axis actuator 108, and the slider 110 holds the pressurized water jet gun 88 via the holder 112.

Then, after the adherend W is carried into the chamber 94 of the tape peeling section 32 and stopped at the tape peeling position on the placing plate 38, the pressurized water jet gun 88 causes the adherend W to move in the width direction (X-axis). Direction) and the length direction (Y-axis direction), the pressurized water is jetted toward the adherend W and sprayed onto the tape T. As a result, the tape T attached to the adherend W is peeled off.

The movement program for moving the pressurized water jet gun 88 in the X-axis direction and the Y-axis direction is performed at the tape peeling position of the adherend W and the sticking position of the tape T adhered to the adherend W in the chamber 94. Accordingly, the control means 35 is programmed in advance. Therefore, the stop position (Y-axis direction position) of the adherend W, which is the tape peeling position, and the widthwise position (X-axis direction position) of the adherend W are accurate in accordance with the movement program of the pressurized water jet gun 88. Will need to be positioned. In particular, when the square tape T is attached only to the opening side portion of the square frame as in the adherend W of FIG. It is necessary to intensively spray pressurized water on a certain area.

In this case, regarding the stop position, the control means 35 may control the adherend conveying means 34 to control the carry-in magnet means 42A stop position. However, as described above, the adherend transporting means 34 is a method in which the back side of the adherend W is adsorbed by the magnet means 42 via the mounting plate 38 to the tape peeling section 32 in the width direction. The position is determined when the adherend W is attracted to the carry-in magnet means 42A. Therefore, when the adherend W is attracted by the magnet means 42, if there is a deviation in the width direction (X-axis direction) of the adherend W with respect to the movement program, the tape peeling performance at the tape peeling portion 32 is adversely affected. I'm concerned about it

As a countermeasure against this, in the adherend transporting means 34 in the present embodiment, before the adherend W is attracted by the magnet means 42, the above-mentioned positioning means 40 positions the adherend W on the mounting plate 38. In the delivery, the position of the adherend W with respect to the mounting plate 38 is preliminarily determined so that the widthwise position of the adherend W becomes the widthwise position of the tape peeling section 32. Thereby, the tape peeling performance can be improved.

When the supply robot 26 (see FIG. 2) of the supply station 12 described above is provided with a function of positioning the adherend W in the width direction with respect to the width direction of the mounting plate 38, the adherend is adhered. The positioning means 40 of the body transport means 34 can be omitted. Further, by providing the adherend transfer means 34 with a moving function in the X-axis direction in addition to the moving function in the Y-axis direction, the positioning means 40 can be omitted. However, these methods have a complicated structure and increase the apparatus cost.

FIG. 6 is an explanatory diagram illustrating the pressurized water jet gun 88.
As shown in FIG. 6A, the pressurized water ejection gun 88 is mainly composed of a nozzle head 98 for ejecting pressurized water and an oscillating rotation mechanism 114 for oscillatingly rotating the nozzle head 98.

Here, the swinging rotation means that the nozzle head 98 rotates about its axis (rotation) and the axis of the nozzle head 98 moves (swings) in a circular locus (revolution). It means performing a combined rotary motion that combines the two motions of and.

As shown in FIG. 6A, the holder 112 that holds the pressurized water jet gun 88 is formed in a box shape, and the swing rotation mechanism 114 and the motor 116 that imparts rotational power to the swing rotation mechanism 114 inside the holder 112. And are provided. Further, an upper surface opening 118 and a lower surface opening 120 are formed on the upper surface and the lower surface on the one end side of the holder 112.

In the swinging and rotating mechanism 114, a bearing member 122 is fixedly installed at a position of an upper surface opening 118 inside the holder 112, and a hollow spindle 124 is vertically rotatably supported by the bearing member 122. Then, the lower end of the pressurized water pipe 128 is connected to the upper end of the spindle 124 via the rotary joint 126, and the pressurized water hose 130 (pressure resistant hose) is connected to the upper end. As a result, even if the spindle 124 rotates, the pressurized water pipe 128 and the pressurized water hose 130 do not rotate.

Further, the pressurized water hose 130 is connected to a pressurized water supply means (not shown) (for example, an ultra-high pressure plunger pump), and high pressure pressurized water is supplied to the nozzle head 98 of the pressurized water jet gun 88 and sprayed onto the adherend W. The water pressure of the pressurized water ejected from the pressurized water ejection gun 88 is preferably in the range of 30 to 100 MPa, more preferably 30 to 50 MPa. The amount of pressurized water ejected from the pressurized water ejection gun 88 is preferably in the range of 15 to 25 liters/minute. The distance between the ejection surface 98A of the nozzle head 98 on which the ejection nozzles 132 are formed and the adherend is preferably in the range of 20 to 30 mm.

Further, the center of the upper surface of a disk-shaped hollow eccentric plate 134 having the same rotation axis L1 as the spindle 124 is fixed to the lower end of the hollow spindle 124. As a result, the spindle 124 and the eccentric plate 134 communicate with each other to form a flow path for the pressurized water. A balance weight 136 is provided on the side surface of the eccentric plate 134.

On the other hand, the upper end of the nozzle pipe 138 of the nozzle head 98 is fixed to the lower surface of the eccentric plate 134 at the position of the eccentric axis L2 that is eccentric with respect to the rotational axis L1 of the spindle 124, and the nozzle pipe 138 is also fixed. The shaft center coincides with the eccentric shaft center L2. As a result, the nozzle head 98 is connected to the pressurized water supply means via the nozzle pipe 138, the hollow eccentric plate 134, the hollow spindle 124, the pressurized water pipe 128, and the pressurized water hose 130.

Further, a pulley 140 is provided at the lower end of the spindle 124 protruding from the bearing member 122. On the other hand, inside the holder 112, the motor 116 is fixed in parallel with the bearing member 122 downward, and the pulley 142 is provided on the motor rotation shaft 116A. Then, the timing belt 144 is stretched between the pulley 142 of the motor 116 and the pulley 140 of the spindle 124.

As a result, when the motor 116 is driven, the spindle 124 rotates and the nozzle head 98 eccentrically rotates via the eccentric plate 134. Therefore, the nozzle head 98 combines the two rotational motions, the circumferential motion and the combined rotary motion. The swing rotation is performed.

Further, as shown in FIG. 6B, the nozzle head 98 that swings and rotates is formed in a cylindrical shape, and has a plurality of ejection nozzles (ejection ports) 132, 132... On the ejection surface 98A. In the present embodiment, the nine nozzle ejection ports 132 are arranged in a grid pattern.

As described above, since the nozzle head 98 swings and rotates, the collision loci of the pressurized water ejected from the pressurized water ejection gun 88 and impinging on the adherend W overlap with each other as compared with the case where only the rotation (rotation) occurs. The collision density can be increased. Furthermore, by forming a plurality of ejection nozzles 132 (ejection ports) in the nozzle head 98 that swings and rotates, the collision density of the pressurized water can be further increased. Thereby, the peeling force for peeling the tape T of the adherend W increases.

(Collection means)
7A and 7B are explanatory views for explaining the tape collecting means 96, FIG. 7A is a perspective view, and FIG. 7B is a side view. The adherend transfer means 34, the pressurized water jet gun 88, etc. are not shown.

As shown in FIG. 7, the tape recovery means 96 mainly includes a tape recovery gun 146, a storage tank 148, a recovery opening 150 opened in the mounting plate 38, a recovery opening 150, and a storage tank 148. And a duct 152 that connects the two.

The tape recovery gun 146 is provided on one of the left and right side plates 94A and 94A of the chamber 94, which is opposite to the recovery opening 150 formed on the mounting plate 38. The tape collecting gun 146 is composed of a plurality (six in FIG. 7) of ejection nozzles 146A, 146A... Supported at regular intervals in the Y-axis direction, and the ejection nozzle 146A has a pressurized water supply means (not shown) (for example, Ultra high pressure plunger pump). The plurality of ejection nozzles 146A eject the pressurized water in the X-axis direction along the upper surface of the mounting plate 38 and toward the recovery opening 150. The water pressure of the pressurized water ejected from the tape collecting gun 146 may be smaller than the water pressure of the pressurized water ejection gun 88 for tape peeling.

The storage tank 148 has an openable/closable discharge door 148A for discharging the collected tape T from the storage tank 148, and a discharge pipe 148B for discharging the pressurized water accumulated in the storage tank 148 from the storage tank 148. As a result, the tape T separated from the adherend W by the pressurized water ejection gun 88 is recovered in the storage tank 148 through the duct 152 from the recovery opening 150 together with the pressurized water ejected from the tape recovery gun 146. You can As the pressurized water accumulated in the storage tank 148, both the pressurized water from the pressurized water jet gun 88 and the pressurized water from the tape collecting gun 146 are accumulated.

Further, it is more preferable to provide an air blow nozzle 154 in the tape collecting means 96 as in the present embodiment.

As shown in FIG. 7, a plurality of (two in FIG. 7) air blow nozzles 154, 154,... Are provided on the front plate of the chamber 94 where the carry-in port 90 is formed and the back plate where the carry-out port 92 is formed. The air blow nozzle 154 is connected to an air supply blower (not shown). The air blow nozzle 154 blows air along the upper surface of the mounting plate 38 in the Y-axis direction. As a result, the tape T separated from the adherend W is easily blown up by the air from the air blow nozzle 154 and easily separated from the adherend W. Therefore, when used in combination with the tape collecting gun 146, the work of collecting the tape T is facilitated. Further, by using the air blow nozzle 154 after collecting the tape T with the tape collecting gun 146, water attached to the upper surface of the adherend W can be removed (drained).

In FIG. 7, the air blow nozzles 154 are provided on both the front plate having the carry-in port 90 of the chamber 94 and the back plate having the carry-out port 92, but either one may be provided.

Although the tape collecting gun 146 and the air blow nozzle 154 are provided as the components of the tape collecting means 96 in the present embodiment, they can be used when the tape is peeled off. That is, the pressurized water jet gun 88 sprays the pressurized water from a direction perpendicular (orthogonal) to the adherend W, whereas the tape collecting gun 146 sprays the pressurized water along the surface of the adherend W. As a result, the tape peeling performance can be improved by using the pressurized water jet gun 88 and the tape collecting gun 146 at the same time or alternately. Further, since the air blow nozzle 154 produces a tape peeling action different from the pressurized water, the tape peeling performance can be improved by using the pressurized water jet gun 88, the tape collecting gun 146 and the air blow nozzle 154 together.
Next, the tape peeling method of the present invention using the tape peeling device 28 configured as described above will be described.

[Tape peeling method]
The control means 35 controls the operation of each device of the tape peeling device 28.

In the present embodiment, the magnet means 42 will be described as a case where there are two magnet means 42A for carrying in and magnet means 42B for carrying out.

The adherends W before tape peeling loaded on the supply station 12 are sucked and conveyed one by one to the positioning means 40 of the tape peeling device 28 by the supply robot 26. That is, the supply robot 26 adsorbs the upper surface of the adherend W and bridges the adherend W on the pair of endless belts 56 provided on the belt conveyor 48 of the positioning means 40. The pasting target body W is conveyed to the transfer position by the endless belt 56 while being guided to both sides W _A in the guide roller 50 in the width direction of the pasting target body W (X axis direction). By this conveyance, the width direction position (X-axis direction position) of the adherend W at the tape peeling position in the tape peeling unit 32 is positioned (positioning step).

Next, the belt conveyor 48 of the positioning means 40 is lowered to the position of the mounting plate 38 by the vertical movement means 52. As a result, the adherend W is transferred from the belt conveyor 48 to the mounting plate 38 and mounted. Then, the magnet holding plate 60 of the carry-in magnet means 42A is raised by the elevating means 64 to bring the magnet holding plate 60 into contact with the back surface of the mounting plate 38. As a result, the back surface of the adherend W placed on the mounting plate 38 is attracted to the four permanent magnets 62 via the mounting plate 38 (adsorption step).

Next, the magnet holding plate 60 attracting the adherend W is moved in the longitudinal direction (Y-axis direction) of the mounting plate 38 by the reciprocating means 44 and stopped at the tape peeling position in the chamber 94. As a result, the adherend W is slid on the mounting plate 38 and carried into the tape peeling section 32 (carrying-in step).

In the first tape peeling operation when the tape peeling device 28 is started, the carry-out magnet means 42B moves from the tape peeling section 32 to the delivery position of the mounting plate 38 without adsorbing the adherend W. Alternatively, the adherend W to which the tape is manually peeled by the worker may be attracted to the carry-out magnet means 42B only during the first tape peeling operation. As a result, the unloading magnet means 42B also conveys the adherend W from the tape peeling section 32 to the inspection station 16 from the mounting plate 38 to the delivery position where the adherend W is delivered.

Next, while the adherend W carried into the tape peeling section 32 is attracted to the permanent magnet 62 of the carrying-in magnet means 42A, the pressurized water jet gun 88 is moved in the XY axis directions by the movement program, and Pressurized water is sprayed onto the area of the adherend W to which the tape T is adhered to separate the tape T (tape separating step). As a result, the conventional problem of adhesive adhesion can be solved, and moreover, the tape T adhered to the adherend W can be reliably and neatly peeled off.

In addition, in the tape peeling device 28 of the embodiment of the present invention, not only the tape T is peeled from the adherend W by the pressurized water, but also the surface of the adherend W (tape T It is also possible to perform cleaning of the surface on which the is peeled off.

Next, the pressurized water is ejected from the tape collecting gun 146 and the tape T separated from the adherend W is sent together with the pressurized water from the collecting opening 150 to the storage tank 148 via the duct 152. In this way, the tape T separated from the adherend W is collected (collection step). In this collecting step, air can be blown from the air blow nozzle 154 onto the adherend W to assist the tape recovery or to remove water droplets adhering to the adherend W.

After the tape is peeled off, the loading magnet means 42A is moved down by the elevating means 64. As a result, the loading magnet means 42A detaches the adherend W. Then, by the reciprocating means 44, the carrying-in magnet means 42A returns from the tape peeling position of the mounting plate 38 to the delivery position, and the carrying-out magnet means 42B returns from the sending position to the tape peeling position.

The carrying-in magnet means 42A that has returned to the delivery position adsorbs the next adherend W delivered to the placement plate 38 by the positioning means 40. On the other hand, the carrying-out magnet means 42B that has returned to the tape peeling position attracts the first adherend W to which the tape has been peeled off in the tape peeling section 32. Then, the reciprocating means 44 moves the carrying-in magnet means 42A from the transfer position of the mounting plate 38 to the tape peeling position, and the carrying-out magnet means 42B from the tape peeling position to the sending position.

Thereby, the carrying-in magnet means 42A carries in the adherends W to the tape peeling section 32 one after another, and the carry-out magnet means 42B successively carries the adherends W from which the tape has been peeled to the delivery position. You can

As described above, since the tape peeling method of the present invention uses the high-pressure pressurized water, the drive system equipment, such as the adherend conveying means 34, which constitutes the tape peeling device 28 is exposed to the pressurized water or the pressurized water enters. Otherwise, there is a risk of equipment failure.

Therefore, if, for example, a roller conveyor is used as the adherend conveying means 34, pressurized water easily enters the bearing portion and the power transmission portion that transmits power to the roller conveyor, which causes a failure. This requires frequent maintenance.

On the other hand, in the adherend conveying means 34 of the tape peeling device 28 of the present invention, the upper side region of the mounting plate 38 where the pressurized water is jetted by the mounting plate 38, the magnet means 42, and the vertical movement means 52. The lower region of the mounting plate 38 on which the drive system devices such as the reciprocating means 44 are disposed is partitioned off. Then, the back surface of the adherend W placed on the placing plate 38 is adsorbed by the magnet means 42 via the placing plate 38, and the reciprocating means 44 moves the magnet means 42 to move the placing plate. A carrier structure in which the adherend W is slid on the 38 and carried is adopted. That is, the structure is such that it is not necessary to dispose the drive system of the adherend transfer means 34 in the upper region of the mounting plate 38 from which the pressurized water is ejected. This prevents the pressurized water from splashing on the drive train equipment.

By using the adherend transfer means 34 of this transfer structure, it is possible to prevent pressurized water from entering and entering the drive system devices, so that it is difficult to cause a failure and maintenance can be reduced.

Further, a chamber 94 having the mounting plate 38 as a bottom surface is provided in the tape peeling portion 32 provided with the pressurized water jet gun 88 so that the pressurized water jetted from the pressurized water jet gun 88 does not splash to the outside of the chamber 94.

Then, the pressurized water ejected into the chamber 94 is collected in the storage tank 148 of the tape collecting means 96 together with the peeled tape T. As a result, it is possible to reliably prevent the pressurized water from splashing into or entering the drive train devices.

Next, the pressurized water cleaning device 30 incorporated in the cleaning station 18 will be described.

Since the pressurized water cleaning device 30 of the present embodiment is incorporated in the cleaning station 18 of the tape peeling cleaning line 10, the case of the adherend W after the tape has been peeled off as the cleaning target will be described. However, it goes without saying that the pressurized water cleaning device 30 of the present invention can be used as a separate cleaning device without being incorporated in the tape peeling cleaning line 10.

[Pressurized water cleaning device]
FIG. 8 is an explanatory diagram illustrating the pressurized water cleaning device 30 incorporated in the cleaning station 18 of the tape peeling cleaning line 10. Further, FIG. 9 is a top view of the pressurized water jetting rod-shaped gun 156 and the eccentric rocking mechanism 158 of the pressurized water cleaning device 30 as viewed from above.

As shown in FIGS. 8 and 9, the pressurized water cleaning device 30 includes a hollow base 160, and a cleaning chamber 162 provided on the base 160 and having a width (X-axis direction) narrower than that of the base 160. Attached to the device frame 164.

The pressurized water cleaning device 30 is mainly provided with a roller conveying means 166 for sandwiching and conveying the adherend W with an upper roller 166A and a lower roller 166B, and a roller length of the roller conveying means 166 provided below the roller conveying means 166. Driving side eccentric rocking mechanism 158A arranged on one end side in the direction, driven side eccentric rocking mechanism 158B arranged on the other end side in the roller length direction of roller conveying means 166, and driving side eccentric rocking mechanism. Both ends of the motor 168, which applies an eccentric rocking force to the 158A by eccentric rotation, and the drive-side eccentric rocking mechanism 158A and the driven-side eccentric rocking mechanism 158B are supported, and the driving-side eccentric rocking mechanism 158A driven by the motor 168. A long plate-shaped rocking plate 170 that rocks in conjunction with the eccentric rocking of the driven side eccentric rocking mechanism 158B and eccentrically rocks the driven side eccentric rocking mechanism 158B. A pressurized water jet rod gun 156 having a rod-shaped nozzle head 172 in which a plurality of jet nozzles 172A, 172A for jetting pressurized water are arranged at intervals in the shank direction, and a control means 35 for controlling the pressurized water cleaning device 30. Composed. A dedicated control means for controlling the pressurized water cleaning device 30 may be provided.

That is, in the roller conveying means 166, the upper roller 166A and the lower roller 166B are rotatably supported at the upper positions of the side walls 162A, 162A of the cleaning chamber 162 via the bearings 174, 174,. Further, a plurality of roller conveying means 166 are arranged in the Y-axis direction, which is the front and back direction of FIG. 8, and the adherend W for which tape peeling has been confirmed at the inspection station 16 is conveyed while being sandwiched in the cleaning chamber 162.

The drive-side eccentric rocking mechanism 158A and the driven-side eccentric rocking mechanism 158B are arranged on the base 160 so as to face the outsides of the side walls 162A of the cleaning chamber 162.
The drive-side eccentric rocking mechanism 158A and the driven-side eccentric rocking mechanism 158B have basically the same structure, and will be described with the drive-side eccentric rocking mechanism 158A drawn as a cross-sectional view so that the inside can be seen on the right side of FIG. To do.

The drive side eccentric rocking mechanism 158A mainly includes a main spindle 178 rotatably supported by the body 176, and an eccentricity provided at the tip of the main spindle 178 at a position eccentric to the axis of the main spindle 178. The spindle 180 includes an eccentric oscillating member 182 rotatably supported by the eccentric spindle 180, and a balance weight 184 that prevents rotational shake of the main spindle 178.

That is, in the drive-side eccentric rocking mechanism 158A, the tubular body 176 is vertically supported on the base 160, and the pair of bearings 186 and 186 are provided at the upper end and the lower end of the body 176. The main spindle 178 is rotatably supported by the pair of bearings 186.

The lower end of the main spindle 178 protrudes from the bearing 186, and is connected to the rotary shaft 168A of the motor 168 disposed inside the base 160 through an opening 188 formed in the upper part of the base 160. The upper end of the main spindle 178 supports the center of the lower surface of the disc-shaped eccentric plate 190. An eccentric spindle 180 is erected on the upper surface of the eccentric plate 190 at a position eccentric to the axis of the main spindle 178.

The cylindrical eccentric rocking member 182 is rotatably supported by the eccentric spindle 180 via a pair of upper and lower bearings 192 and 192. A balance weight 184 is provided on the side of the eccentric plate 190 to prevent the main spindle 178 from rotating.

When the amount of eccentricity (the axial center distance between the shaft center 178A of the main spindle 178 and the shaft center 180A of the eccentric spindle 180) is small, the eccentric spindle 180 can be directly provided on the main spindle 178 without the eccentric plate 190. Is.

The driven-side eccentric rocking mechanism 158B differs from the drive-side eccentric rocking mechanism 158A in that the balance weight 184 is preferably provided and the motor 168 is not provided.

Then, both ends of the rocking plate 170 are supported by the eccentric rocking member 182 of the drive-side eccentric rocker 158A and the eccentric rocking member 182 of the driven-side eccentric rocking mechanism 158B. That is, the oscillating plate 170 is disposed in the X-axis direction through the oscillating openings 194 and 194 formed at the central positions of the side walls 162A of the cleaning chamber 162, and both ends of the oscillating plate 170 are respectively described above. The eccentric rocking members 182, 182 are connected to the connecting portions 182A, 182A by bolt members or the like. The swing opening 194 is formed in such a size that it does not hit the side walls 162A of the cleaning chamber 162 when the swing plate 170 swings eccentrically, which will be described later. Thus, the eccentric rocking mechanism 158 that eccentrically rocks the rocking plate 170 is configured.

Therefore, when the motor 168 is rotationally driven, the main spindle 178 of the drive side eccentric rocking mechanism 158A rotates, and the eccentric spindle 180 eccentrically rotates via the eccentric plate 190. By the eccentric rotation of the eccentric spindle 180, the eccentric oscillating member 182 rotatably supported by the eccentric spindle 180 eccentrically oscillates to describe an oscillating locus of a gyration circular motion. As a result, the rocking plate 170 connected to the eccentric rocking member 182 also interlocks with the eccentric rocking of the eccentric spindle 180 to perform the eccentric rocking of the circular turning motion. Further, the eccentric oscillating member 182 of the driven-side eccentric oscillating mechanism 158B eccentrically oscillates in a turning circular motion in conjunction with the eccentric oscillating of the oscillating plate 170.

That is, the driven-side eccentric rocking mechanism 158B moves in a driven manner via the rocking plate 170 in conjunction with the eccentric rocking of the drive-side eccentric rocking mechanism 158A by the rotational driving of the motor 168. As a result, the eccentric oscillating mechanism 158A and the driven eccentric oscillating mechanism 158B do not deviate from each other in eccentric oscillating motion, so that the eccentric oscillating mechanism 158 can be operated smoothly.

Incidentally, the driven-side eccentric rocking mechanism 158B can also be provided with a motor 168 to synchronize with the drive-side eccentric rocking mechanism 158A, but smooth eccentric rocking is hindered due to synchronization deviation, etc. It is easy to apply excessive force to.

The eccentric amount of the drive side eccentric oscillating mechanism 158A and the driven side eccentric oscillating mechanism 158B (axial center distance between the shaft center 178A of the main spindle 178 and the shaft center 180A of the eccentric spindle 180) may be in the range of 5 mm to 7 mm. preferable.

Further, as shown in FIG. 8, in the cleaning chamber 162, a space below the rocking plate 170 ejects pressurized water from the pressurized water ejecting rod-shaped gun 156 to store the dirty water for cleaning the back surface of the adherend W to be retained 162B. It has become. A drain hose 196 for discharging the dirty water accumulated in the storage portion 162B is connected to the lower portion of one side plate forming the storage portion 162B of the both side walls 162A of the cleaning chamber 162.

The pressurized water jet rod-shaped gun 156 has a rod-shaped nozzle head 172 fixed on the rocking plate 170 via connecting plates 198, 198. The length of the nozzle head 172 is slightly longer than the width (X-axis direction) of the adherend W, and a pair of pressurized water supply ports 200, 200 for supplying pressurized water into the nozzle head 172 are formed at both ends. It A pressure-resistant water hose 202 having a pressure resistance is connected to the pair of pressurized water supply ports 200. A plurality of ejection nozzles 172A and 172A are linearly arranged at equal intervals between the pair of pressurized water supply ports 172 in the longitudinal direction of the nozzle head 172. Although 24 ejection nozzles 172A are provided in the present embodiment, the number is not limited to this.

Then, the pressurized water supplied to the nozzle head 172 is jetted upward from the plurality of jet nozzles 172A, and is sprayed on the back surface (lower surface) of the adherend W to be sandwiched and transported by the roller transport means 166.
Next, a method for cleaning pressurized water using the pressurized water cleaning device 30 configured as described above will be described.

[Pressurized water washing method]
The control means 35 controls the operation of each device of the pressurized water cleaning device 30.

In the inspection station 16, the adherend W whose tape peeling has been confirmed is conveyed at a constant speed in the cleaning chamber 162 by the roller conveying means 166.

Then, the motor 168 is driven to operate the eccentric oscillating mechanism 158, and at the same time, the pressurized water is ejected from the ejection nozzles 172A of the nozzle head 172 of the pressurized water ejection rod gun 156 to convey the back surface of the adherend W to be conveyed. Spray pressurized water toward.

As a result, the pressurized water jet rod-shaped gun 156 mounted on the rocking plate 170 is attached from the plurality of jet nozzles 172A arranged on the nozzle head 172 of the pressurized water jet rod-shaped gun 156 while performing the eccentric swing of the swirling circular motion. The pressurized water is sprayed on the back surface of the dressing W. In other words, since each of the ejection nozzles 172A linearly arranged in the nozzle head 172 performs a circular movement, the pressurized water ejected from the adjacent ejection nozzles 172A overlap each other.

As a result, the collision loci of the pressurized water ejected from the ejection nozzles 172A and impinging on the adherend W overlap, so that the cleaning energy density of the pressurized water can be increased. Therefore, the effect of cleaning the adherend W can be dramatically improved as compared with the case where the pressurized water jet bar-shaped gun 156 is in a stationary state or only when it is linearly swung.

Since the pressurized water cleaning device 30 of the present embodiment is configured as a device for cleaning the back surface of the adherend W, the pressurized water jet bar gun 156 and the eccentric rocking mechanism 158 are arranged only below the roller conveying means 166. However, if it is provided both below and above the roller conveying means 166, both sides of the adherend can be washed at once.

( Tape collection means)
7A and 7B are explanatory views for explaining the tape collecting means 96, FIG. 7A is a perspective view, and FIG. 7B is a side view. The adherend transfer means 34, the pressurized water jet gun 88, etc. are not shown.

Although the tape collecting gun 146 and the air blow nozzle 154 are provided as the components of the tape collecting means 96 in the present embodiment, they can be used when the tape is peeled off. That is, the pressurized water jet gun 88 sprays the pressurized water from a direction perpendicular (orthogonal) to the adherend W, whereas the tape collecting gun 146 sprays the pressurized water along the surface of the adherend W. As a result, the tape peeling performance can be improved by using the pressurized water jet gun 88 and the tape collecting gun 146 at the same time or alternately. Further, since the air blow nozzle 154 produces a tape peeling action different from the pressurized water, the tape peeling performance can be improved by using the pressurized water jet gun 88, the tape collecting gun 146 and the air blow nozzle 154 together.
Next, a tape peeling method using the tape peeling device 28 configured as described above will be described.

As described above, since the tape peeling method using the tape peeling device of the present invention uses the high-pressure pressurized water, the pressurized water is not applied to the drive system devices constituting the tape peeling device 28, for example, the adherend conveying means 34. If it is splashed or if pressurized water enters, there is a risk of equipment failure.
