  By the way, the transfer is performed, for example, in a clean room, but in the conventional transfer, since the molded product is disposed below and the mold is disposed above, the air is transferred between the mold and the molded product. There is a possibility that transfer defects such as fine particles that are slightly present fall on the molded product due to gravity and the shape of the transferred fine pattern deteriorates.

  Therefore, it is possible to consider a measure for preventing a transfer failure due to fine particles in the air by disposing a mold on one side in the horizontal direction and a molded product on the other side.

  However, when the mold and the molded product are arranged in the horizontal direction, it is necessary to prevent the mold or the molded product itself from dropping due to gravity. Therefore, it is necessary to hold the mold or the molded product with the mold holding body or the molded product holding body by vacuum suction or a clamper.

  If the molded product is held by vacuum suction, a hole or groove for vacuum suction must be provided on the flat surface of the molded product holder where the back surface of the molded product comes into surface contact. When holes and grooves are provided in this way, when the mold and the molded product are pressed to transfer, the pressure of the transfer of the part of the molded product that contacts the hole or groove is higher than that of the part where there is no groove. There is a problem that there is a possibility that a transfer defect may occur due to insufficient pressing force at a portion of the molded product that contacts the hole or groove. This problem is a problem that occurs not only when the molded product is held by vacuum suction but also when the mold is held by vacuum suction.

It is configured with.

  Here, the molded product W and the like to be transferred by the transfer system 1 (transfer device 3) will be described in detail with examples.

  2 and 3 are diagrams showing a manufacturing process of the HDD substrate including a transfer process of the molded product W2 (molded product W).

  The molded product W2 is, for example, a base of a discrete media HDD substrate having track bits. FIG. 2A shows a molded product W2 before transfer. FIG. 2B shows the product W2 and the like when the product W2 is sandwiched between the molds MA and MB (each mold M) for transfer. FIG. 3C shows the molded product W2 after transfer.

  As shown in FIG. 2 (a), for example, the molded product W2 before transfer is formed of palladium (Pd) having a thickness of about 30 nm on both sides in the thickness direction of a flat glass disk substrate W1 having a diameter of 2.5 inches. ) A base layer and a perpendicular magnetic recording material cobalt chromium platinum (CoCrPt) having a thickness of about 50 nm are deposited to form the magnetic layers W3A and W3B. , W5B are deposited, and the resist films W7A, W7B are applied on the SiO2 films W5A, W5B, for example, by spin coating.

  As will be described in detail later, a fine transfer pattern (transfer formed with fine irregularities) formed on the mold M is formed on the molded product W2 before transfer shown in FIG. Pattern) is transferred (see FIG. 2B).

  As shown in FIG. 3C, in the molded product W2 after the transfer, the fine uneven patterns of the respective molds MA and MB are transferred onto the surfaces of the resist films W7A and W7B. As the resist films W7A and W7B, an ultraviolet curable resin (UV resin), a thermosetting resin, a thermoplastic resin, or the like can be used. In the state shown in FIG. 2A, the resist films W7A and W7B are cured. However, it is cured during the transfer shown in FIG.

  Subsequently, as shown in FIG. 3D, the magnetic layers W3A and W3B are patterned. Specifically, the SiO2 films W5A and W5B are etched by RIE (Reactive Ion Etching) until the surfaces of the magnetic layers W3A and W3B are reached by using the resist films W7A and W7B transferred with fine irregularities as a mask. Then, the magnetic layers W3A and W3B are etched using this pattern. The groove region thus formed becomes the separation region. The patterned magnetic layers W3A and W3B form a recording track band.

Thereafter, the surfaces of the SiO2 films W9A and W9B are polished and flattened by chemical mechanical polishing (CMP). Then, by forming diamond like carbon as the protective films W11A and W11B on the entire surface, a magnetic recording medium (HDD substrate) WP is obtained as shown in FIG.

  The transfer system 1 (transfer device 3) is in charge of the steps shown in FIGS. 2A, 2B, and 3C among the manufacturing steps shown in FIGS. . Moreover, although it is not clear in FIG.2 and FIG.3, the to-be-molded product W and each type | mold M (MA, MB) are formed in the thin disc shape which has a circular center through-hole in the center part.

  Next, the transfer device 3 will be described in detail.

  4 is a front view showing a schematic configuration of the transfer device 3, FIG. 5 is a view taken along arrow V in FIG. 4, FIG. 6 is a view taken along arrow VI in FIG. 4, and FIG. 4 is a view taken along arrow VII in FIG. 4, FIG. 8 is a view taken along arrow VIII-VIII in FIG. 4, and FIG. 9 is an enlarged view of a portion IX in FIG.

  10 is a view (enlarged view) in the direction of arrow X in FIG. 4, FIG. 11 is a side view of FIG. 10, and FIG. 12 is a diagram showing the installation body 13 and the pressing body 15 of the transfer device 3. It is. In addition, the installation body 13 shown in FIG. 9 or the like is provided with a jig 17 on which a temporary assembly TA composed of a mold M (MA, MB) and a product to be molded W is installed.

  The transfer device 3 is, for example, a fine transfer formed on one surface in the thickness direction of the circular flat plate-shaped workpiece W on one surface in the thickness direction of the first mold MA in the circular flat plate shape. A fine transfer pattern formed on one surface in the thickness direction of the circular flat plate-shaped second mold MB is formed on the other surface in the thickness direction of the circular flat plate-shaped article W by transferring the pattern. This is a transfer device, and is configured to include an installation body 13 on which the jig 17 is detachably installed, and a pressing body 15 facing the installation body 13.

  As shown in FIG. 9, the jig 17 includes a main body member 19 and a support member constituting member 21 and is integrally configured. Accordingly, the jig 17 includes a disc-shaped base end portion 23 having a predetermined thickness, a disc-shaped distal end portion 25 having a predetermined thickness, and a columnar (pin-shaped) support body. 27. The proximal end portion 23, the distal end portion 25, and the support body 27 are arranged coaxially, and are connected in the order of the proximal end portion 23, the distal end portion 25, and the support body 27. The outer diameter of the base end portion 23 is larger than the outer diameter of the distal end portion 25, and the outer diameter of the support body 27 is smaller than the outer diameter of the distal end portion 25.

  On the outer periphery of the distal end portion 25 on the base end portion 23 side, a ring-shaped recess (a gripped portion) 29 is formed, and the temporary assembly TA is installed by the temporary assembly transport means 11 17 is transported, the hand 31 of the temporary assembly transport means 11 is engaged with the gripped portion 29 (see FIGS. 13, 14, and 29), and the jig 17 on which the temporary assembly TA is installed is removed. It is designed to grip. Note that the jig 17 may be integrally formed without being configured as a separate body, such as the main body member 19 and the support member constituting member 21.

  In the temporary assembly TA, the mold MA, the workpiece W, and the mold MB are overlapped in this order in the thickness direction. More specifically, in the temporary assembly TA, one surface in the thickness direction of the mold MA on which the fine transfer pattern is formed and one of the surfaces in the thickness direction of the molded product W onto which the fine transfer pattern is transferred. The thickness of the molded product W to which the fine transfer pattern is transferred and one surface in the thickness direction of the mold MB on which the fine transfer pattern is formed are overlapped with each other. The other surfaces in the direction overlap each other in surface contact. The temporary assembly TA is formed in a circular flat plate shape having a central through hole (see FIGS. 9 and 12).

  A circular installation surface 33 having a predetermined size is formed on the jig 17. The installation surface 33 is configured by a flat surface (end surface in the thickness direction) of the distal end portion 25. When the temporary assembly TA is installed on the jig 17, one surface in the thickness direction of the temporary assembly TA is in surface contact with the installation surface 33. More specifically, when the temporary assembly TA is installed on the jig 17, the back surface of the mold MB in the temporary assembly TA (the other surface in the thickness direction of the mold MB where the fine transfer pattern is not formed). The entire surface (the entire back surface of the mold MB corresponding to the surface on which the fine transfer pattern is formed) is in surface contact.

  Further, the installation surface 33 is not provided with any grooves or holes used for vacuum suction or the like for holding the temporary assembly TA, and the installation surface 33 is completely provided if negligible processing errors are ignored. It has a flat surface.

  As already understood, the support body 27 is provided on the jig 17 so as to protrude vertically from the central portion of the installation surface 33. The support 27 is used when the temporary assembly TA is installed on the jig 17 (including after the installation), and when the jig 17 on which the temporary assembly TA is installed is installed on the installation body 13. It is intended to prevent the temporary assembly TA from dropping due to gravity by being fitted in the center through hole of the temporary assembly TA in advance (including after installation). In addition, the support 27 is arranged so that the temporary assembly TA is mounted on the installation surface 33 in the direction in which the installation surface 33 is deployed (for example, in the Y-axis direction shown in FIG. 9). It is for positioning.

  Further, a ring-shaped detachment preventing body 18 is fitted to the front end side of the support body 27 from the position where the temporary assembly TA is fitted, along with the temporary assembly TA. This disengagement prevention body 18 is located more than the position where the temporary assembly TA is fitted when the support 27 is fitted into the central through hole of the temporary assembly TA to prevent the temporary assembly TA from falling. The temporary assembly TA is prevented from coming off from the support 27 by being fitted to the front end side of the support 27 side by side with the temporary assembly TA. More specifically, this is for preventing the temporary assembly TA from being inclined obliquely. Therefore, the protruding length of the support 27 from the installation surface 33 is such that when the disengagement prevention body 18 is fitted to the front end side of the support 27 in this way, the tip protrudes beyond the disengagement prevention body 18. Such extended dimensions are set.

  The ring-shaped detachment prevention body 18 is configured to have a thickness and weight sufficiently larger than the temporary assembly TA, and both end surfaces of a predetermined size are formed on a plane perpendicular to the axial direction. Further, since the thickness is sufficiently larger than the temporary assembly TA, the axial length of the fitting surface of the anti-detachment body 18 with respect to the support body 27 is set to be equal to or larger than the diameter of the support body 27. ing.

  In addition, as shown in FIG. 12, when the temporary assembly TA is installed in surface contact with the installation surface 33, the temporary outer surface of the support 27 fitted in the central through hole of the temporary assembly TA is temporarily installed. At a position protruding outward from the assembly TA, a stepped portion 27a is provided for making the diameter smaller so that the tip end side is disengaged from the position and fitted into the prevention body 18. On the other hand, when the ring-shaped detachment prevention body 18 is fitted to the support body 27, the end of the inner peripheral surface 18a on the side adjacent to the temporary assembly TA interferes with the stepped portion 27a on the support body 27 side. An annular relief recess 18b to be avoided is provided. When the temporary assembly TA and the detachment prevention body 18 are fitted on the outer periphery of the pin-shaped support body 27, the fitting gap between the detachment prevention body 18 and the support body 27 is fitted into the support body 27 of the temporary assembly TA. It is set to be larger than the gap.

  The installation body 13 is formed in a columnar shape having a disc-shaped flange 35 on the base end side. The flange 35 is supported by the moving body 37 of the transfer device 3. A cylindrical recess 39 is provided at the distal end portion of the installation body 13, and the base end portion 23 of the jig 17 is formed on the side surface and the bottom surface (a plane developed in the Y-axis direction) of the recess 39. By fitting (fitting) and clamping the jig 17 with the clamper 41 (see FIGS. 10 and 11), the jig 17 is integrally installed at a predetermined position of the installation body 13. ing. In this way, the installation surface 33 of the jig 17 installed on the installation body 13 faces the horizontal direction. That is, when a straight line orthogonal to the planar installation surface 33 is assumed, the assumed straight line extends in the horizontal direction.

  As shown in FIG. 9, the pressing body 15 is formed in a columnar shape having a disc-shaped flange 43 on the base end side. At the tip of the pressing body 15, there is provided a pressing surface 45 that is a plane that comes into surface contact with the end surface of the detachment prevention body 18 that is disposed on the other surface (back surface of the mold MB) side of the temporary assembly TA. The pressing surface 45 is a plane of a predetermined size that is parallel to and faces the installation surface 33 of the jig 17 installed on the installation body 13. The pressing surface 45 and the both ends of the detachment support 18 are not provided with any grooves or holes for vacuum-sucking the mold MB, and are completely flat if processing errors are ignored. Yes.

  Then, in order to sandwich and press the temporary assembly TA installed on the installation body 13 via the jig 17 between the installation body 13 and the pressing body 15 (see FIG. 15), the pressing body 15 The installation body 13 can be moved and positioned relative to the pressing body 15 in a direction (X-axis direction) approaching / separating from the pressing body 15. As already understood, when the temporary assembly TA is sandwiched and pressed between the installation body 13 and the pressing body 15, one surface in the thickness direction of the temporary assembly TA (the back surface of the mold MA) is the installation surface. The other surface in the thickness direction of the temporary assembly TA (the back surface of the mold MB) is in surface contact with one end surface of the detachment preventing body 18. In addition, a hole 47 into which the tip of the support body 27 enters when the pressing is performed is provided in the center of the pressing surface 45 of the pressing body 15. The outer diameter of the support 27 is slightly smaller than the inner diameter of the hole 47.

  The pressing body 15 is provided with an air passage (through hole) 49, and one end of the air passage 49 communicates with the bottom of the hole 47. The other end of the air path 49 is connected to a filter (not shown) and a negative pressure generator (not shown) such as a vacuum pump. The installation body 13 and the pressing body 15 connect the temporary assembly TA and the detachment prevention body 18 together. When sandwiched and pressed, the air in the hole 47 is sucked to remove fine particles present in the hole 47 in an extremely small amount.

  Similarly, the installation body 13 is also provided with an air path (through-hole) 51, and when the jig 17 is installed on the installation body 13, the air in the recess 39 is sucked into the recess 39. The fine particles generated by contact with the side surface of the jig 17 and the side surface of the base end portion 23 of the jig 17 or the fine particles originally existing in the recess 39 are removed.

  The installation body 13 is supported by the moving body 37 via the load cell 53. Then, the pressing force when the temporary assembly TA installed in the jig 17 is sandwiched and pressed by the installation body 13 and the pressing body 15 is measured by the load cell 53, and the control device 55 (FIG. 1) is measured. ), Control is performed so that the pressing force by the pressing body 15 (installation body 13) becomes a predetermined pressing force determined in advance according to the detection result of the load cell 53.

  Further, when the jig 17 on which the temporary assembly TA is installed is installed on the installation body 13, the strain generating body of the load cell 53 is caused by the rotational moment due to the weight of the temporary assembly TA, the jig 17 and the installation body 13. Although distortion occurs in the (strain generation section) 58, the transfer device 3 is provided with a distortion reduction means 56 for reducing the distortion.

  Explaining in detail with an example, the load cell 53 is configured to include, for example, a main body portion 57 having a circular through hole 54 in the central portion and formed in a disk shape with a predetermined thickness. An annular concave portion 59 is formed in the middle portion of the radial direction 57. By forming the concave portion 59, the main body portion 57 includes an annular central portion 61, an annular strain generating portion 58 positioned outside the central portion 61, and the strain generating portion 58. It is divided into an annular outer peripheral portion 63 located outside.

  The central portion 61 is provided integrally with the installation body 13 via the spacer 66, and the outer peripheral portion 63 is provided integrally with the moving body 37. The strain generating portion 58 is provided with a strain gauge (not shown). Then, when a rightward force is applied to the installation body 13 in FIG. 9, distortion occurs in the strain generating portion 58, and the pressing force of the temporary assembly TA by the installation body 13 and the pressing body 15 can be measured. It can be done.

  A cylindrical guide member 65 is integrally provided at the center of the base end portion of the installation body 13. For example, the guide member 65 is engaged with the cylindrical guide member support 67 in a sliding pair, and the guide member 65 is almost free from rattling with respect to the cylindrical guide member support 67. Thus, it can be moved in the X-axis direction. That is, the outer diameter of the guide member 65 is very slightly smaller than the inner diameter of the guide member support 67. The cylindrical guide member support body 67 is provided integrally with the moving body 37 described later in detail. As a result, the rotational moment due to the weight of the temporary assembly TA, the jig 17 and the installation body 13 can be received by the guide member 65 and the cylindrical guide member support 67, and the strain generating portion 58 of the load cell 53 can be received. The generated strain (initial strain) can be reduced.

  The guide member 65 and the guide member support 67 are located in the through hole 54 provided in the center of the main body 57, and the load cell 53 and the spacer 65 are recessed portions 69 formed in the moving body 37. Located in. Further, as the cylindrical guide member support 67, a linear guide bearing that rolls against the guide member 65 may be adopted. In this case, it is desirable that radial pressure is applied to the guide member 65 engaged with the cylindrical guide member support 67.

  The mold holder 121 is provided integrally with the base body 123 above the base body 123. A lower portion 131 of the mold holding body 121 is configured in the same manner as the pressing body 15 of the transfer device 3 described above. However, the lower portion 131 is provided with an air path 132 for vacuum-sucking the mold MB, and the back surface (upper surface) of the mold MB is brought into contact with the planar lower surface of the lower portion 131 to perform vacuum suction. The type MB is held.

  The jig holder 119 is positioned below and away from the mold holder 121, the jig holder 119 holds the jig 17 on which the mold MA is installed, and the mold holder 121 is the mold. In a state where the MB is held, the molded product W before being transferred is placed on the mold MA, and the jig holder 119 is raised until the molded product W contacts the mold MB. Temporary assembly in which the mold MA, the workpiece W, and the mold MB overlap each other on the jig 17 by releasing the holding of the mold MB by the mold holding body 121 and moving the jig holding body 119 downward. TA is set up.

  Next, the robot 12 that attaches and removes the detachment prevention body 18 to the upper side of the temporary assembly TA installed in the jig 17 will be described. As shown in FIG. 1 with a simplified arrow, the robot 12 first grips a ring-shaped detachment prevention body 18 that has been retracted to a position that does not interfere with the assembly of the temporary assembly TA, and a jig 17 It is placed on the temporary assembly TA assembled above and serves to fit the support 27. Further, at the time of separation, the detachment preventing body 18 placed on the upper side of the temporary assembly TA that has been transferred is gripped and lifted, and is again retracted to a position that does not interfere with the assembly of the next temporary assembly TA. .

  Note that the molded product W before being transferred is transported from the stocker 5 by the molded product transport means 9. In addition, the jig 17 in which the mold MA, the workpiece W, and the mold MB are stacked is released from the holding of the jig holder 119 by the clamper 41, and then transferred by the temporary assembly transport unit 11. 3 and is installed on the installation body 13 of the transfer device 3.

  Further, the jig 17 on which the temporary assembly TA including the molded product W transferred by the transfer device 3 is installed is unloaded by the temporary assembly transport means 11 and held by the temporary assembly / separation unit 7. It is designed to be installed on the body 119.

  Thereafter, the jig 17 is held by the clamper 41, the jig holder 119 is raised, the mold holder 121 is brought into contact with the mold MB, the mold MB is held by vacuum suction, and the jig holder 119 is lowered. Thus, the mold MB is separated from the assembly TA.

  In this state, the mold MA and the molded product W to which the transfer has been performed are installed on the jig holder 119 together with the jig 17. After this, the molded product W that has been transferred is conveyed to the stocker 5 by the molded product conveying means 9.

  Next, the stocker 5 will be described.

  As shown in FIG. 1, the stocker 5 includes a stocker 5A that stores a molded product W before transfer and a stocker 5B that stores a molded product W after transfer. The stocker 5A is configured so that a plurality of disk-shaped molded products W are arranged so that their thickness directions are in the vertical direction, and the molded products W are arranged at predetermined intervals in the vertical direction. And can be stored. The stocker 5B is configured similarly to the stocker 5A.

  Next, the molded product conveying means 9 will be described in detail.

  The molded product conveyance means 9 includes, for example, a first molded product conveyance means 133 configured by a single axis robot, a second molded product conveyance means 135 configured by a single axis robot, and a cylindrical coordinate robot. And a third article-conveying means 137 configured as described above.

  The single-axis robot 133 conveys the molded product W before transfer between the stocker 5A for the molded product before transfer and the cylindrical coordinate robot 137. The single-axis robot 135 is a cylindrical coordinate robot. The molded product W after transfer is transported between 137 and the stocker 5B for the molded product after transfer. The cylindrical coordinate type robot 137 conveys the molded product W between the uniaxial robots 133 and 135 and the temporary assembly / separation unit 7.

  24 (a) is a plan view of the single-axis robot 133, and FIG. 24 (b) is a side view of the single-axis robot 133. As shown in FIG. Is configured to include a housing 139 and a movable body 141 that can be moved and positioned in the Y-axis direction with respect to the housing. A clamper 143 is provided at the tip of the moving body 141, and the disc-shaped workpiece W is clamped by the clamper 143 and conveyed in the Y-axis direction. Clamping by the clamper 143 is performed by gripping the arc-shaped outer periphery of the workpiece W in the vertical direction. The housing of the stocker 5A can be moved and positioned in the vertical direction, and each molded product W stored in the stocker 5A can be carried out by the single-axis robot 133 one by one. . Note that the second molded article conveying means (one-axis robot) 135 (see FIG. 25) is also configured in the same manner as the one-axis robot 133 except that the moving stroke of the moving body 141 is different.

  As shown in FIG. 26 (side view of the cylindrical coordinate type robot 137) and FIG. 27 (plan view of the cylindrical coordinate type robot 137; XXVII arrow view in FIG. 26), the third article conveying means (cylindrical coordinate type) The robot 137 includes a housing 145 and an arm 147 extending in the horizontal direction. The arm 147 is movable and positionable in the Z-axis direction, and is also rotatable and positionable about an axis CL2 that extends in the Z-axis direction through the center of the housing 145.

  The axis CL2 passes through the base end side of the arm 147 in the longitudinal direction. A clamper 149 is provided on the tip end side of the arm 147, and the disc-shaped workpiece W is clamped and conveyed by the clamper 149. Clamping by the clamper 149 is performed by using two opposing members 151 and 153 on two arcuate outer peripheral portions (two opposing outer peripheral portions) of the molded product W. It is designed to be sandwiched with very little force from the direction. As described above, since the part holding the molded product W is different from each single-axis robot 133, 135, the cylindrical coordinate robot 137 holds the molded product W without interfering with each single-axis robot 133, 135. It can be held instead. That is, for example, the workpiece W held by the single-axis robot 133 can be held by the cylindrical coordinate robot 137 while being held.

  In addition, projections 155 and 157 for preventing the molded product W from falling are formed at the lower ends of the members 151 and 153 constituting the clamper 149 (FIG. 2A, FIG. 28 (c)). And when installing the molded product W in the temporary assembly / separation unit 7, the outer diameter of the mold MA is made larger than the outer diameter of the molded product W in order to avoid interference between the members 151, 153 and the mold MA. Slightly smaller.

  As shown in FIG. 1, the clamper 149 of the cylindrical coordinate robot 137 moves along an arcuate locus. Then, a single molded product W is received from the robot 133 at the position P1 and conveyed to the position P2 of the temporary assembly / separation unit 7, and a single molded product W is received at the position P2 of the temporary assembly / separation unit 7. , It is transported to the position P3 and delivered to the uniaxial robot 135.

  Next, the temporary assembly transport unit 11 will be described in detail.

  The temporary assembly transport unit 11 transports the temporary assembly TA and the disengagement prevention body 18 installed in the jig 17 between the temporary assembly / separation unit 7 and the transfer device 3 (temporary assembly TA and disengagement). The prevention body 18 is transported together with the jig 17), and is composed of, for example, an articulated robot 159. As shown in FIG. 29, a band (clamper) 31 is provided at the tip of the arm of the articulated robot 159, and the jig 17 can be held and transported by the clamper 31. .

  Next, the operation of the transfer system 1 will be described.

  As an initial state, the molded product W before transfer is stored in the stocker 5A, and the robots 133, 135, 137, 159 and the transfer device 3 do not hold the molded product W or the jig 17, It is assumed that the temporary assembly / separation unit 7 holds the jig 17 in which only the mold MA is installed and the mold MB (see FIG. 21).

  In this initial state, under the control of the controller 55, the robot 133 takes out one molded product W from the stocker 5A and transports it to the position P1 in FIG. Then, the workpiece W having the position P1 is held by the robot 137 and conveyed to the position P2 of the temporary assembly / separation unit 7 (see FIGS. 1 and 22). From the state shown in FIG. 22, the arm 147 of the robot 137 is lowered (the jig holder 119 may be raised), the product W is brought into contact with the mold MA installed on the jig 17, and the clamper is moved. The holding by 149 is released and the product W is placed on the mold MA. Thereafter, the arm 147 of the robot 137 is rotated to retract the clamper 149 (arm 147) from the position P2.

  Subsequently, the jig holder 119 is raised so that the product W and the mold MB are brought into contact with each other so that the mold MA, the product W, and the mold MB overlap in this order on the jig 17 from below ( Thereafter, the holding of the mold MB by the mold holding body 121 is released, and the jig holding body 119 is lowered. Thereby, temporary assembly TA is installed in the jig | tool 17 (refer FIG. 20). In this state, one surface in the thickness direction of the temporarily assembled temporary assembly TA (the back surface of the mold MA) is in surface contact with the installation surface 33 of the jig 17. Even if a part of the temporary assembly TA (through hole in the center) is in contact with (fitted to) the support body 27 provided in the jig 17, The assembly TA is prevented from dropping due to gravity. In the above state, the temporary assembly TA is positioned and installed with respect to the installation surface 33 in the deployment direction of the installation surface 33.

  Next, under the control of the control device 55, the robot 12 is moved, and the detachment prevention body 18 is placed on the upper side of the temporary assembly TA and fitted to the support body 27.

  Subsequently, the jig (the jig in which the temporary assembly TA and the detachment prevention body 18 are installed) 17 existing at the position P2 is gripped by the hand 31 of the robot 159 (see FIG. 20), and the robot 159 is moved. Then, it is transported to the transfer device 3 and installed in the transfer device 3. Thereafter, the arm of the robot 159 is retracted.

  The jig 17 in which the temporary assembly TA is installed is installed in the transfer device 3. The robot 159 conveys the jig 17 to a predetermined space between the installation body 13 and the pressing body 15. Then, change the orientation from a vertical posture to a horizontal posture.

  Thereafter, the installation body 13 (moving body 37) is moved, the installation body 13 and the jig 17 are engaged, and the jig 17 installed on the installation body 13 is clamped by the clamper 41. The installation of the jig 17 on the installation body 13 is completed (see FIGS. 13 and 14). Then, by installing the jig 17 on the installation body 13 in this way, the installation surface 33 of the jig 17 faces the horizontal direction, and the support body 27 also faces the horizontal direction.

  In this state, the installation body 13 (moving body 37) is moved, and the pressing body 15 and the installation body 13 sandwich the temporary assembly TA to perform transfer (see FIG. 15). At this time, the detachment preventing body 18 is interposed between the pressing body 15 and the temporary assembly TA, and one end surface of the detachment prevention body 18 comes into surface contact with the other surface of the temporary assembly TA (the back surface of the mold MB). In the state where the other end surface of the disengagement prevention body 18 is in surface contact with the pressing surface 45 of the pressing body 15, transfer by pressing is performed.

  Subsequently, a jig (post-transfer jig) 17 in which a temporary assembly TA including a molded product W on which fine transfer patterns are transferred on both surfaces in the thickness direction and a detachment prevention body 18 are installed is used as a robot 159. Is transferred from the transfer device 3 to the temporary assembly / separation unit 7 (see FIG. 20).

  After this transfer, the arm of the robot 159 is retracted, and the removal prevention body 18 at the uppermost stage is removed by the operation of the robot 12. Subsequently, the jig 17 installed on the jig holder 119 of the temporary assembly / separation unit 7 is clamped by the clamper 41 of the jig holder 119, the jig holder 119 is raised, and the mold MB and the mold are held. The body 121 is brought into contact with the mold holder 121 to hold the mold MB (see FIG. 23), and the jig holder 119 is lowered (see FIG. 21).

  Subsequently, the product to be molded (the product to be molded placed on the mold MA installed on the jig 17 installed on the jig holder 119) W is transported to the position P3 by the robot 137, and is transported. The molded product W is transported to the stocker 5B by the robot 135, stored in the stocker 5B, and the initial state is restored.

  By the way, when installing the jig 17 on the installation body 13 of the transfer device 3 in the transfer system 1, the jig 159 is positioned at a predetermined position by the robot 159, and the installation body 13 (moving body) of the transfer apparatus 3 is placed. 37) is moved, but the installation body 13 may be stopped at a predetermined position, and the jig 17 may be moved by the robot 159. When configured in this way, the pressing body 15 may be configured to be moved and positioned in the X-axis direction instead of or in addition to the installation body 13 (moving body 37).

  According to the transfer device 3, when the temporary assembly TA is fitted on the support body 27 of the jig 17, the disengagement prevention body 18 is fitted on the upper side thereof, so that the jig 17 is set in the transfer device 3. When the installation surface 33 of the jig 17 and the support 27 are oriented in the horizontal direction, or the jig 17 in which the temporary assembly TA is installed between the transfer device 3 and the temporary assembly / separation unit 7 is used. It is possible to prevent the temporary assembly TA from being detached from the support 27 when transporting.

  That is, since the support body 27 protruding in the horizontal direction is fitted in the central through hole of the temporary assembly TA, the load of the temporary assembly TA is supported by the support body 27, and thereby the temporary assembly TA. Is prevented from falling due to gravity, but with that alone, the temporary assembly TA may fall off when the support 27 is oriented in the horizontal direction. Therefore, it is conceivable to simply increase the protruding dimension of the support 27. However, simply increasing the length of the support 27 prevents the temporary assembly TA from falling off the support 27. The position of the solid TA does not change easily. In order to cope with this, the transfer device 3 is provided with a detachment prevention body 18.

  This detachment prevention body 18 is sufficiently larger in thickness than the temporary assembly TA and sufficiently large in weight. Accordingly, since the frictional resistance between the support 27 and the support 27 becomes larger than that of the temporary assembly TA in the state of being fitted on the outer periphery of the support 27, the resistance against the ease of falling off can be greatly increased. Therefore, it is possible to prevent the position shift and dropout. Further, in order for the detachment prevention body 18 to fall off, the detachment prevention body 18 must slide in the axial direction at least as much as its thickness, so that the detachment prevention body 18 is oriented even though the orientation of the support 27 is horizontal. There is almost no possibility that the temporary assembly TA will fall off, thereby reliably preventing the temporary assembly TA from falling off.

  As described above, even when the installation surface 33 is oriented in the horizontal direction, the temporary assembly TA and the detachment prevention body 18 are stably installed on the installation body 13 together with the jig 17. Without providing a clamper, it is possible to suppress the occurrence of transfer failure to the molded product W with a simple configuration.

  That is, by flowing air with a higher degree of cleanness, for example, from above to below, in the space between the pressing body 15 and the temporary assembly TA installed on the jig 17 installed on the installation body 13, Since the particulates existing in the air in the space around the temporary assembly TA can be prevented from being retained and the particulates can be eliminated, and the temporary assembly TA is held by the jig 17 without vacuum suction. The installation surface 33 of the jig 17 (installation surface with which the temporary assembly TA comes into contact) 33, the both end surfaces of the detachment prevention body 18 and the pressing surface 45 of the pressing body 15 can be made to be almost completely flat, and transfer is performed. It is possible to press the entire surface of the product W or the molds MA and MB with a uniform pressing force, and to prevent the occurrence of transfer failure due to a partial lack of pressing force.

  Further, since it is not necessary to hold the temporary assembly TA with the jig 17 using a clamper, the configuration of the apparatus is simplified, and a thin plate-like temporary assembly TA is applied by partially applying a clamping force with the clamper. The risk of bending is avoided, and the occurrence of transfer defects can be prevented.

  In addition, since the temporary assembly TA is installed in the jig 17, the temporary assembly (temporary assembly before being transferred to the molded product W) TA is installed in the transfer device 3, or the temporary assembly TA is temporarily installed. When unloading the assembly (temporary assembly transferred to the product W) TA from the transfer device 3, the robot 159 may hold the jig 17, and the temporary assembly TA can be easily transported.

  Further, according to the transfer device 3, when the jig 17 on which the temporary assembly TA is installed is installed on the installation body 13, the rotational moment due to the weight of the temporary assembly TA, the jig 17, and the installation body 13 is obtained. Since distortion generated in the strain generating body 58 of the load cell 53 can be reduced, the pressing force at the time of transfer can be made correct, and accurate transfer can be performed.

  Further, the transfer device 3 includes the piezo element 75 that elastically deforms the central portion of the pressing surface 45 of the pressing body 15 so as to protrude slightly toward the installation body 13 side. It is possible to prevent the phenomenon that the transfer is not performed at the center of the molded product W or the transfer becomes insufficient.

  Incidentally, the transfer system 1 includes one transfer device 3, one stocker 5, one temporary assembly / separation unit 7, one robot 133, one robot 135, and one robot. 159, but the number of each device may be changed according to the process work time (tact time) of each device.

  For example, if the tact time of the transfer device 3 is about half that of the other devices, one transfer device 3, two stockers 5, two temporary assembly / separation units 7, and two The robots 133, 135, 137, and 159 may constitute a system.

  In addition, in the transfer system 1, the product W is sandwiched between the molds MA and MB, and transfer is performed on both surfaces in the thickness direction of the product W, but one of the molds MA and MB is transferred. A fine transfer pattern may be transferred only to one surface in the thickness direction of the product W without using a mold (see FIG. 30).

  In the transfer device 3, the ring-shaped detachment prevention body 18 is shown separately from the mold M. However, the detachment prevention body 18 is formed integrally with the adjacent mold MB from the beginning. Is also possible.

  Further, the transfer system 1 may be configured such that the jig 17 is deleted.

  That is, when installing the temporary assembly in which the transfer device is a plane of a predetermined size facing in the horizontal direction and the mold and the molded product overlap, one surface of the temporary assembly An installation body having an installation surface that is a plane in contact with the surface, and a horizontal penetration of the temporary assembly when the temporary assembly protrudes horizontally from the installation surface and is installed in surface contact with the installation surface. By fitting into the hole, a support body that supports the temporary assembly and prevents the temporary assembly from dropping due to gravity, and both end faces are formed in a plane perpendicular to the axial direction, and the support body is the temporary assembly. When the temporary assembly is prevented from falling by being fitted into the central through-hole of the assembly, it is aligned with the temporary assembly at the front end side of the support body from the position where the temporary assembly is fitted. A ring-shaped disengagement that prevents the temporary assembly from coming off from the support by fitting. A pressing surface for pressing the other surface of the temporary assembly through the anti-separation body, which is a flat surface of a predetermined size facing the stationary body and the installation surface of the installation body in parallel. It is good also as a transfer device which has a press body which is provided and has a temporary assembly installed in the installation body sandwiched and pressed in cooperation with the installation body.
