[Problems to be Solved by the Invention] The outer dimensions of the molded object may vary due to machining errors that occur during machining. Therefore, there are cases in which the side portion of the molding object cannot be supported by the support portion of the conveying device, or the gap between the support portion and the molding object becomes large. In this case, there is a concern that the molding target cannot be conveyed by the conveying device, or the mounting position may deviate when the molding target is mounted on the molding target mounting portion.

Therefore, the subject of the present invention is to provide a conveying device capable of conveying a molded object even if there is a deviation in the outer dimension of the molded object, and capable of suppressing the deviation of the mounting position of the molded object mounting portion of the molding die, Resin molding apparatus and resin molded product manufacturing method. [Technical means to solve the problem]

In order to solve the above-mentioned problems, the conveying device of the present invention is an apparatus for conveying a molded object to a molding die of a resin molding apparatus, and is characterized by including a molded object holding portion, the molded object holding portion including: a molded object A placement portion on which the molded object is placed; and a plurality of edge restriction members provided on the periphery of the molded object placement portion or the outside of the molded object placement portion to restrict the A member of the edge of the molded object and can move in the direction of the inside of the molded object mounting portion.

The resin molding apparatus of the present invention is characterized by including: the conveying device; and a molding die, including a first mold having a molding object mounting portion for mounting the molding object, and a second mold disposed opposite to the first mold 2 molds.

The method for manufacturing a resin molded product of the present invention is characterized by including: a step of holding a molded object during loading, placing the molded object on a molded object mounting portion provided in a molded object holding portion of a conveying device, and setting it on The peripheral edge of the molded object placement portion or the outer side of the molded object placement portion and a plurality of edge restriction members that restrict the edges of the molded object face toward the edge of the molded object placement portion The inner direction is moved to thereby hold the molded object in the molded object holding portion; the molded object carrying-in step is to adjust the position of the molded object placement portion to the molded object mounting portion of the molding die The aligning method moves the molded object holding portion, and after the molded object is mounted on the molded object mounting portion, the molded object holding portion is moved to the outside of the molding die, so The molding mold includes a first mold having the molded object mounting portion on which a molded object is mounted, and a second mold disposed opposite to the first mold; and a resin molding step, in which the first mold and the After the second mold is closed, the molded object is resin molded. [Effects of the invention]

According to the present invention, even if there is a deviation in the outline size of each molding object, the molding object can be conveyed, and the deviation of the mounting position of the molding object mounting portion toward the molding die can be suppressed.

In the conveying device, the resin molding device, and the resin molded product manufacturing method of the present invention, the molded object is placed on the molded object placement portion, and the edge restriction member is directed toward the inside of the molded object placement portion. By moving in the direction, the molded object is held in the molded object holding portion. In this way, by using the movable edge restriction member, even if there is a deviation in the outline size of the molded object, the molded object can be held. In addition, since the edge restricting member can be moved so as to reduce the gap between the edge restricting member and the molded object, it is possible to suppress deviation of the position where the molded object is mounted on the molded object mounting portion.

The shape of the edge restriction member is not particularly limited. In addition, the type and shape of the molded object are also not particularly limited. Examples of the types of molding objects to which the present invention can be applied include semiconductor wafers, circuit boards, lead frames, glass substrates, metal substrates, etc., and examples of the shapes of molding objects include circles, rectangles, other polygons, and ellipses. Wait.

The method of manufacturing a resin molded product of the present invention may further include: a step of holding a molded object during unloading, and after the resin molding step, the first mold and the second mold are opened to load the molded object The molded object holding portion is moved so that the position of the placement portion is aligned with the molded object mounting portion, and the molded object that has been resin molded and mounted on the molded object mounting portion is placed on the molded object mounting portion. The molded object placement portion moves the edge restricting member toward the inside of the molded object placement portion, thereby holding the molded object in the molded object holding portion; and carrying out A step of moving the molded object holding portion to the outside of the molding die.

In addition to the above-mentioned processing error caused during the processing, the deviation in the outline size of the molded object also occurs due to, for example, the following reasons. An example of the first cause is due to thermal expansion of the molded object. During the resin molding, the first mold and the second mold are heated to a temperature at which resin molding can be performed, so the temperature of the molded object becomes higher than the temperature before molding immediately after the resin molding. In order to improve production efficiency, it is necessary to remove the molded object from the molded object mounting part and carry it out to the outside of the molding die before the temperature drops sufficiently. Therefore, when the molded object is moved out, thermal expansion occurs compared to when it is moved in. The outer dimensions are different from when it was moved out. In addition, if the material of the molding object is different, the coefficient of thermal expansion is different, and therefore the outer size of the molding object also differs depending on the material of the molding object. As an example of the second cause, the problems that occur when overmold described below is performed are listed. Secondary molding refers to performing resin molding to the outside of the object to be molded, and is used when performing fan-out packages in which wiring or input/output terminals are also arranged on the outside of a resin-sealed wafer. The shape of the molded object that has undergone secondary molding becomes larger than the original shape, and therefore the outer dimensions of the molded object are different between when it is carried in and when it is carried out. According to the conveying device, resin molding device, and resin molded product manufacturing method of the present invention, the molded object can be held in any of the examples of the first cause and the second cause, and the molded object can be prevented from being molded. The position where the object is attached to the molded object attachment portion is deviated.

In addition, in the examples of the first and second reasons, the outer dimensions of the molded object are different when the molded object is loaded into the molding die and when the molded object is removed from the molding die. Therefore, it is described in Patent Document 1. In the resin molding apparatus described in, the conveying device (offloader) for unloading is provided separately from the conveying device (loading machine) for carrying in, which is a factor in increasing the cost of the resin molding device. In contrast to this, in the conveying device, resin molding device, and resin molded product manufacturing method of the present invention, the same conveying device is used when carrying in and when carrying out, so that the cost can be suppressed.

In the conveying device and the resin molding device of the present invention, it is desirable that the molded object holding portion further includes an urging member, and the urging member opposes the plurality of edge restriction members in the direction (molded object The direction of the inside of the mounting part) to apply force. In addition, in the method for manufacturing a resin molded product of the present invention, it is desirable that the plurality of edge restriction members are urged by the urging member in the state in which the molded object is held in the molded object holding portion. Apply force in the direction. Thereby, while the molded object is held in the molded object holding portion, the molded object is held by the plurality of edge restriction members that are urged toward the inside of the molded object placement portion by the urging member. Therefore, the molded object can be held more stably. For example, there are cases where the molded object holding portion and the molded object held by the molded object are close to the first mold and the second mold that have increased in temperature, and the molded object holding portion and the molded object correspond to their respective thermal expansion coefficients. Produce swelling. Even in this case, it is possible to stably hold the molded object by urging the plurality of edge restriction members in the direction of the inside of the molded object mounting portion.

In the conveying device of the present invention, a configuration including the following members can be adopted: a plate-shaped rotating member that rotates around the center of rotation; Each of the restricting members is provided with one for each of the end edge restricting members to be inserted through and capable of moving the end edge restricting member; and an end edge restricting member movement restricting portion relative to the plurality of end edge restricting members One is provided for each, and the direction in which the end edge restricting member can move is restricted to a straight line passing through the end edge restricting member and the center of rotation. Such a conveying device can be used for the resin molding apparatus and the resin molded product manufacturing method of the present invention.

According to the configuration having the rotating member, the guide long hole of the edge restricting member, and the movement restricting portion of the edge restricting member, by rotating the rotating member around the center of rotation, the edge restricting member guides the long hole in the edge restricting member. The position changes, and accompanying this, the edge restriction member moves on a straight line passing through the edge restriction member and the rotation center such that the distance from the rotation center changes. Thereby, the edge restriction member can be moved in the direction of the inside of the molding object placement part, or in the opposite direction of the said direction.

The guide hole of the end edge restriction member can be configured as follows: a distance between a point on a center line in the width direction connecting the center of the guide hole of the end edge restriction member in the width direction and the rotation center is different from the point The distance between a point on the center line in the width direction and the center of rotation is different. Thereby, when the end edge restricting member moves between the two points in the guide long hole of the end edge restricting member by the rotation of the rotating member, the distances between the two points and the center of rotation are different from each other. The edge restricting member moves on a straight line passing through the end edge restricting member and the center of rotation. The "width direction" as used herein refers to a point on the outer edge of the long hole that guides the edge restricting member, and the point that sandwiches the inside of the long hole of the end edge restricting member and is located at the shortest distance. State the direction in which another point on the outer edge connects.

The following configuration can be adopted: the end edge restricting member guides the elongated hole so that the distance between the point on the center line in the width direction and the center of rotation increases as the point moves from one end of the center line in the width direction to the other end Way to form. Thereby, when the rotating member is rotated in either clockwise or counterclockwise direction in a plan view, the edge restricting member moves close to the center of rotation, and when the rotating member is rotated in the opposite direction, the edge restricting member Move away from the center of rotation.

In the conveying device and the resin molding apparatus having the urging member, it is desirable to further include an urging member control unit that starts/stops the operation of the urging member (ON/OFF) . In addition, in the step of holding the molded object at the time of loading (and the step of holding the molded object at the time of unloading) in the method of manufacturing a resin molded product using the operation of the urging member, it is desirable that the molded object Before placing on the molded object placement portion, the operation of the urging member is stopped, and after the molded object is placed on the molded object placement portion, the force of the urging member The action begins. Thereby, when the molded object is placed on the molded object placement portion, the plurality of edge restriction members are not urged toward the inside of the molded object placement portion by the urging member, so that the The plurality of end edge restricting members and the forming object simultaneously place the forming object on the forming object placing portion.

In the conveying device and the resin molding device of the present invention, it is desirable that all of the plurality of edge restriction members can move in the direction in conjunction with each other. In addition, in the method of manufacturing a resin molded article of the present invention, it is desirable that when the plurality of edge restriction members are moved in the direction, all of the plurality of edge restriction members are interlocked with each other. Move in the direction described. Thereby, the molded object can be held in the vicinity of the center of the molded object holding portion, and the accuracy of the attachment position to the molded object attachment portion can be improved.

It is desirable to provide one of the plurality of edge restriction members at a position corresponding to a notch (notch) provided on the molded object placed on the molded object placement portion . Thereby, by aligning the position of the cutout with the edge restriction member to place the molded object on the molded object placement portion, the direction of the molded object on the molded object placement portion can be determined .

A pair of convex rails 211 are provided on the lower surface of the two ends in the one direction of the base frame 21, and the pair of convex rails 211 are in a direction orthogonal to the one direction (the longitudinal direction of FIG. 2(a), Figure 2 (b) in the direction perpendicular to the surface of the paper). The resin molding apparatus 10 is provided with a rail 16 corresponding to the convex rail 211 (not shown in Figs. 2(a) to 2(c). Refer to Figs. 7(a) to 7()), which will be described later. f)) The entire conveying device 20 is guided by these rails to move between the inner side of the forming mold 15 and the outer side of the forming mold 15.

FIG. 3(a) shows a plan view of the elevator frame 22, and FIG. 3(b) shows a plan view of the turret 23. As shown in FIG. A shaft 221 protrudes from the center of the upper surface of the elevator frame 22. A hole 231 through which the shaft 221 is inserted is provided in the center of the turret 23, and the turret 23 rotates with the shaft 221 as the center of rotation.

Ten edge limiting member guide recesses 222 are provided on the lifting frame 22, nine of which are arranged at 40° intervals along the circumference of the outer profile slightly inside the outer profile of the lifting frame 22 (Figure 2(c)) , Figure 3 (a)). The remaining one end edge restricting member guide recess 222A is arranged between two adjacent end edge restricting member guide recesses 222 among the nine edge restricting member guide recesses 222, and is arranged slightly inside of the nine end edge restricting member guide recesses 222 Place. The position in the circumferential direction of the guide recess 222A of the placement edge restricting member only needs to be the same as the position of the cut (notch) provided in the molded object when the molded object is mounted on the molding die (the position that is intended to face the cut). Direction) align and set arbitrarily. The vicinity of the lower surface of the cylindrical edge restricting member accommodating portion 272 (described later) of the one edge restricting member 27 is held in the one edge restricting member guide recess 222 (including the edge restricting member guide recess 222A). The distance between both ends in the extending direction of the straight line (dashed-dotted line in FIG. 3A) of the edge restricting member guide recess 222 intersecting the center of rotation is set to be larger than the diameter of the edge restricting member accommodating portion 272. In addition, the width of the edge restriction member guide recess 222 in the direction perpendicular to the straight line is set to be shorter than the distance and slightly larger than the diameter of the edge restriction member accommodating portion 272 so that the edge restriction member can be accommodated. The portion 272 hardly moves in the direction perpendicular to the straight line, and can move in the direction of the straight line. Thereby, the end edge restricting member 27 is restricted so as to be guided by the end edge restricting member guide recess 222 to move in the direction in which the straight line extends. The edge restriction member guide recess 222 is equivalent to the edge restriction member movement restriction portion.

The turret 23 is plate-shaped and is provided with ten end edge restricting member guide long holes 232, nine of which are arranged along the circumference of the outer profile at 40° intervals slightly inside the outer profile of the turret 23 (Figure 3(b)).

In addition, The left end of the guide long hole 232 of the edge restriction member is set to "r ₁ end" and the right end is set to "r ₂ end") to gradually decrease (hence r ₁ > r ₂ ), relative to taking the center of rotation as The edge restriction member guide long hole 232 is obliquely provided in the tangent direction of the center circle. The nine edge restriction member guide long holes 232 other than the edge restriction member guide long hole 232A are provided in the same shape and at the same slope with respect to the tangential direction. The end edge restricting member guide long hole 232A is directed from the left end to the right end of the center line in the width direction (the definition is the same as that of the other end edge restricting member guide long hole 232, and the end edge restricting member guides the long hole depicted in FIG. 3(b) The position of the hole 232A is from the right end to the left end), and the distance from the center of rotation of the turret 23 is gradually reduced _{from r 3 to r 4} (r ₃ > r ₄ , r ₁ > r ₃ , r ₂ > r ₄ ) It is inclined with respect to the tangent direction. The left end of the guide long hole 232A of the edge restriction member is set to "r ₃ end", and the right end is set to "r ₄ end".

With this structure, when the turret 23 is rotated counterclockwise in a plan view (hereinafter, "counterclockwise" and "clockwise" are specified in plan view), the position of each edge restriction member 27 is guided from the edge restriction member _{The r 1} end side in the long hole 232 _{moves to the r 2} end side (in the end edge restricting member guide long hole 232A, it _{moves from the r 3} end side to the r ₄ end side), thereby the end edge restricting member 27 (27A) The distance from the center of rotation gradually decreases, and it moves in the direction (the direction in which the center of rotation exists) inside the molding target placement portion 25 (FIG. 4( a )). On the other hand, when the turret 23 is rotated clockwise, the position of each end edge restricting member 27 _{moves from the r 2} end side in the _{end edge restricting member guide long hole 232 to the r 1} end side (guided by the end edge restricting member the long hole 232A is moved from the side end r ₄ r ₃ to the end side), whereby the end edge of the restricting member 27 (from 27A) and the center of rotation gradually increases in the direction of the object and the outer mounting portion 25 is moved toward the forming (Figure 4(b)). Here, the nine end edge restricting member guide long holes 232 other than the end edge restricting member guide long hole 232A are provided in the same shape and at the same slope with respect to the tangential direction, whereby the object to be formed is placed During the movement of the inner direction and the outer direction of the portion 25, the nine end edge restricting members 27 other than the end edge restricting member 27A maintain the same distance from the center of rotation. The edge restriction member 27A moves so as to be closer to the center of rotation than the other edge restriction members 27.

The lifting frame 22 is provided with a torsion spring 234 that urges the turret 23 to rotate counterclockwise. Thereby, the edge restriction member 27 is urged in the direction of the inside of the molding object mounting portion 25. The torsion spring 234 and the turret 23 correspond to the urging member. In addition, the urging member is not limited to a torsion spring, and an air cylinder or a servo motor that rotates the turret 23 counterclockwise can also be used.

A cutout 235 is provided on the outer edge of the turret 23. In addition, a stopper 225 is provided on the outer edge of the lifting frame 22. The stopper 225 is urged toward the side of the cutout 235 by a spring, and is arranged at a position to engage with the cutout 235 when the turret 23 is rotated clockwise for one full turn. As described above, the turret 23 is urged by the torsion spring 234 in the counterclockwise rotation (that is, the end edge restricting member 27 is moved in the direction of the inside of the molded object placement portion 25), but by making the stop The mover 225 is engaged with the notch 235 and can stop the turret 23 in a full clockwise rotation (that is, the end edge restricting member 27 is moved toward the outside of the molding target placement portion 25). Furthermore, by disengaging the engaged stopper 225 from the cutout 235, the turret 23 is rotated counterclockwise by the action of the torsion spring 234. The stopper 225 and the cutout 235 correspond to a urging member control unit that starts/stops the operation of the urging member. The position or direction of the stopper 225 is not particularly limited.

The non-rotating frame 24 and the forming object placement portion 25 are provided with end edges having the same planar shape as the end edge restricting member guide recess 222 at positions corresponding to the end edge restricting member guide recess 222 of the elevator frame 22.

The elevating mechanism 26 is a mechanism that is provided on the upper surface of the base frame 21 and raises and lowers the elevating frame 22. Along with the raising and lowering of the lifting frame 22, the turret 23, the non-rotating frame 24, and the forming object placement portion 25 provided on the lifting frame 22 also rise and fall.

As shown in FIG. 5, the edge restriction member 27 has an edge restriction member main body 271, the above-mentioned cylindrical edge restriction member accommodating portion 272, and an elastic member 273. The edge restriction member main body 271 is a cylindrical member having a diameter smaller than that of the cylinder of the edge restriction member accommodating portion 272. The elastic member 273 supports the lower end of the end edge restricting member body 271 and is disposed at the bottom of the end edge restricting member receiving portion 272. When the upper end of the edge restricting member body 271 is pressed, the elastic member 273 is compressed and the upper end is lowered. When the pressing is released, the elastic member 273 stretches, and the upper end returns to the original position. When the upper end of the edge restricting member main body 271 is located at the original position, the upper end passes through the edge restricting member penetration hole 252 and protrudes above the upper surface of the molded object placement portion 25. On the other hand, the upper end of the edge restricting member accommodating portion 272 is located lower than the upper surface of the molding object placement portion 25. The molding object placement portion 25 and the edge restriction member 27 are combined to constitute the molding object holding portion 28.

The lifting frame 22 is provided with four plate-shaped positioning tools 2241 to 2244 for aligning the positions of the conveying device 20 and the upper mold 151 in the lateral direction in the forming mold 15. The positioning pieces 2241 to 2244 are arranged in such a way that when the conveying device 20 is raised from below the upper mold 151, each of the positioning pieces 2241 to 2244 abuts against the four side surfaces of the upper mold 151, respectively.

Next, the rotating frame 23 is rotated clockwise to engage the stopper 225 with the notch 235. Thereby, the edge restriction member 27 moves to the outer side of the molding target object mounting part 25 (FIG. 6(a-1), FIG. 6(a-2)). In this state, the disc-shaped object to be molded (semiconductor wafer) S is arranged inside the area surrounded by the nine edge restricting members 27 on the upper surface of the object placement portion 25. Here, a cut SC is provided on the outer edge of the molded object S, and the position of the cut SC is aligned with the position of the edge restriction member 27A (FIG. 6( a-1 )). In the above state, each end edge restriction member 27 (including the end edge restriction member 27A) is not in contact with the outer edge of the molded object S.

Next, the stopper 225 is disengaged from the notch 235, and the turret 23 is rotated counterclockwise by the action of the torsion spring 234. Thereby, the ten edge restriction members 27 move in the direction of the inside of the molding object placement portion 25 in a coordinated manner. Furthermore, when the end edge restricting member body 271 of the end edge restricting member 27 abuts against the outer edge of the object S, the rotation of the turret 23 is stopped (therefore, the turret 23 does not necessarily rotate one full turn counterclockwise), and the object to be molded The object S is held by the molding target object placement portion 25 (Fig. 6(b-1), Fig. 6(b-2)). In this way, the plurality of end edge restricting members 27 abuts against the outer edge of the molded object placement portion 25 in a coordinated manner, the molded object S is held in the center of the molded object placement portion 25, and the molded object S can be suppressed Position deviation. In addition, even if there is a deviation in the outer dimension of the molded object S due to processing errors or the like, the molded object S can be held by the movement of the edge restriction member 27, and the deviation of the mounting position can be suppressed. Furthermore, in the edge restricting member 27, the edge restricting member 27A arranged at the position of the cut SC is engaged with the cut SC, whereby the position in the circumferential direction of the molded object S is also prescribed, so that the molded object can be identified The direction of the molded object S on the object placement portion 25. At this point, the step of holding the molded object at the time of loading is completed.

After the molding object S is placed on the molding object placement portion 25 in this way, the conveying device 20 is moved along the rail 16 between the upper mold 151 and the lower mold 152 so that the molding object placement portion 25 and The position of the molding target attachment portion 1511 of the upper mold 151 is aligned (FIG. 7( a )).

In this position, the elevating mechanism 26 raises and lowers the portion on the upper side of the lifting frame 22 that includes the molding object placement portion 25, so that the molding object S placed on the molding object placement portion 25 abuts against The molding target attachment portion 1511 (FIG. 7(b)). At this time, the upper end of the edge restricting member main body 271 abuts against the molded object mounting portion 1511 before the molded object S, and then when the lifting mechanism 26 further rises, the elastic member 273 is compressed, thereby interacting with the molded object S. The relative position of the upper surface of the placing portion 25 is lowered. Therefore, the molded object S can be brought into contact with the molded object attachment portion 1511 without being disturbed by the edge restriction member 27.

In such a state that the molding object S is in contact with the molding object mounting portion 1511, gas is sucked from the gas suction hole 1512 by the vacuum pump, whereby the molding object is mounted on the molding object mounting portion 1511. The gas is continuously sucked from the gas suction hole 1512 until the stop time described later. Then, the turret 23 is rotated clockwise to move the edge restricting member 27 toward the outside of the molding object placement portion 25, and after the molding object placement portion 25 and the like are lowered by the elevating mechanism 26, the conveying device 20 moves to the outside of the forming mold 15 (FIG. 7(c)). At this point, the step of carrying in the molded object is completed.

Next, after the mold release film F is laid on the inner surface of the cavity C of the lower mold 152 by a mold release film laying mechanism not shown, the resin material P containing a thermosetting resin is supplied by a resin material supply mechanism not shown. Supply into the chamber C (Figure 7(d)). The release film laying mechanism and the resin material supply mechanism have been widely used in existing resin molding apparatuses, so detailed descriptions are omitted. The resin material P is melted in the cavity C by the heat supplied from the heater 142.

After the resin material P in the cavity C is melted, the crank connecting rod 113 is used to raise the movable platen 121. Thereby, the lower mold 152 on the movable platen 121 abuts against the upper mold 151 and presses the upper mold 151, so that the upper mold 151 is fixed to the fixed platen 122, whereby the upper mold 151 and the lower mold 152 are closed ( Figure 7(e)). After a predetermined time has elapsed in this state, the resin material P is cured, and a resin molded product PS obtained by resin molding on the surface of the molded object S is obtained. At this point, the resin molding step is completed.

After that, the movable platen 121 is lowered by the crank connecting rod 113 to open the forming mold 15 (FIG. 7( f )). Then, the conveying device 20 is conveyed between the upper mold 151 and the lower mold 152 so that the molding target placement portion 25 is aligned with the molding target mounting portion 1511 of the upper mold 151 (FIG. 8(a)) . Then, in the state where the edge restricting member 27 is moved to the outside of the molding object placement portion 25 by rotating the turret 23 to the right (FIG. 6(a-1), FIG. 6(a-2)) Next, the lifting mechanism 26 raises the molded object placement portion 25 and the like, so that the upper surface of the molded object placement portion 25 abuts the lower surface of the resin molded product PS (FIG. 8( b )). Next, the gas suction from the gas suction hole 1512 is stopped, and the molding object placement portion 25 and the like are lowered by the lifting mechanism 26.

Furthermore, by rotating the turret 23 counterclockwise, the edge restricting member 27 is moved toward the inner side of the molding object placement portion 25 (FIG. 6(b-1), FIG. 6(b-2)) to abut On the outer edge of the resin molded product PS. Thereby, the resin molded product PS obtained by resin molding on the surface of the molded object S is held in the molded object holding portion 28. At this time, the resin molded product PS has not been sufficiently cooled, and the outer dimension may be larger than the molded object S before resin molding. However, even in this case, it can be moved by the edge restricting member 27. Keep the resin molded product PS. Similarly, the secondary molded resin molded product PS obtained by resin molding to the outer side of the outer profile of the molded object S can also be moved and held by the edge restricting member 27. At this point, the step of holding the molded object at the time of carrying out is completed.

After that, the conveying device 20 is moved to the outside of the forming mold 15 (carrying out step). Then, in a state where the edge restricting member 27 is moved to the outside of the molding object placement portion 25 by rotating the turret 23 to the right, the resin molded product PS is removed from the molding object placement portion 25, and the The production of this resin molded product PS is completed.

The operations of the conveying device 20 described so far, specifically the rotation of the turret 23, the movement along the rail 16, and the raising and lowering of the molding object placement portion 25 by the elevating mechanism 26 can be automatically performed using power. It can also be done manually by the operator.

Each end edge restriction member 27D is provided with a jig 29 placed on the lifting frame 22 and arranged outside the molding object placement portion 25D. The jig 29 is a rod-shaped material that rotates centered on an axis parallel to the upper surface of the molding target mounting portion 25D, and is arranged such that the projection on the upper surface faces the center of the molding target mounting portion 25D. When one end of the jig 29 descends by rotating, it comes into contact with the edge restriction member 27D, and the edge restriction member 27D is pushed out toward the center of the molding object placement portion 25D.

When the molding object S is transported by the transport device 20D in the third modification, the circular molding object S is placed on the molding object placement portion 25D, and then the clamp 29 is rotated to thereby shape the object The end portion of the jig 29 on the center side of the mounting portion 25D descends, and the edge restriction member 27D including the flexible pin is pushed out toward the center side (FIG. 12 ). Thereby, the edge restriction member 27D is pressed against the end of the molded object S, and the molded object S is fixed to the molded object placement portion 25D. Here, by synchronizing the four jigs 29, the molded object S can be arranged in the center of the molded object placement portion 25D.

The present invention is not limited to the above-mentioned embodiment and modification examples. For example, in the above embodiment, a case where a compression molding device is used is used as an example. However, even if a transfer (transfer) molding device is used instead of the compression molding device, it is possible to use the same conveying device 20, The structure of the conveying device 20B, the conveying device 20C, and the conveying device 20D.

The following stoppers 225A and grooves 226A can be used instead of the urging member control unit including the stoppers 225 and the cutouts 235 provided in the conveying device 20. In FIG. 13( a ), a part of the upper surface of the elevator frame 22 is enlarged for the conveying device 20 provided with the stopper 225A and the groove 226A. The stopper 225A has a rod 2251A attached to the turret 23 and extending in a direction from the center of the turret 23 to the outside, a roller 2252A connected to the rod 2251A, and urges the rod 2251A toward the center of the elevator 22 The elastic member 2253A.
