However, it should be noted that the drawings are schematic, and the relationship between the thickness and the planar dimensions, the ratio of the thickness of each part, and the like are different from the actual ones. Therefore, specific thicknesses and dimensions should be determined in consideration of the following description. Moreover, it is a matter of course that portions having different dimensional relationships and ratios are included between the drawings.
Further, the following embodiments exemplify apparatuses and methods for embodying the technical idea of the present invention, and the technical idea of the present invention is the material, shape, structure, and arrangement of components. Etc. are not specified below. The technical idea of the present invention can be variously modified within the technical scope defined by the claims described in the claims.

FIG. 1 is a schematic configuration diagram showing an example of a transport apparatus to which the present invention is applied. The conveyance device 1 conveys a printed wiring board as a conveyance object, and is a device that conveys a plurality of printed wiring boards stacked one by one to a predetermined place.
The transport apparatus 1 includes a transport pad 2 that holds the printed wiring board by suction and a moving unit 3 that moves the transport pad 2.
In FIG. 1, the transport pad 2 has a suction plate 12, and the transport pad 2 is attached to one end of the arm 4 so that the suction plate 12 is substantially horizontal. The other end of the arm 4 is attached to one end of the arm 5 so as to be rotatable in a plane parallel to the suction plate 12, and the other end of the arm 5 is attached to the arm fixing base 6.

  Then, the position of the transport pad 2 is controlled by controlling the rotation angle of the arms 4 and 5 in the plane parallel to the suction plate 12 and the position of the transport pad 2 in the direction perpendicular to the suction plate 12. The printed wiring boards stacked in a predetermined place as a transport source are picked up one by one by the transport pad 2 and moved to a predetermined transport destination, and then the printed wiring boards are released. In FIG. 1 and the following FIGS. 2 to 5, cables and the like are omitted. The arm 4 and the arm 5 constitute the moving unit 3.

2 to 5 are external views showing an example of the transport pad 2. 2 is a side view, FIG. 3 is a perspective view of the transport pad 2 viewed from the side facing the printed wiring board, and FIG. 4 is a view of the vicinity of the adhesive bar 16 when the transport pad 2 is viewed from the adhesive bar 16 side described later. FIG. 5 is a perspective view showing a part of the transport pad 2 from the side opposite to the surface facing the printed wiring board.
The transport pad 2 includes, for example, four suction fans 11. The suction fan 11 is fixed between the suction plate 12 and the support plate 13 so that the suction surface faces the suction plate 12. The suction fan 11 is a fan capable of sucking printed wiring boards having different shapes and sizes without changing the suction target distance by controlling the rotation speed of the suction fan 11. The suction plate 12 has a plurality of through holes 12a formed on the entire surface. When the suction fan 11 is operated, the printed wiring board, which is a conveyance object, is sucked through the through holes 12a and the suction plate 12 and the print plate 12 are printed. The printed wiring board is sucked and held by contacting the wiring board.

  The suction plate 12 and the support plate 13 have a substantially rectangular plate shape in plan view, and have approximately the same size. The support plate 13 is connected to a ball nut 15 provided at one end of the arm 4 shown in FIG. 1 via a screw shaft 14, and the screw shaft 14 and the ball nut 15 constitute a ball screw unit. By rotating the ball nut 15, the screw shaft 14 moves in a direction perpendicular to the suction plate 12, and thereby the transport pad 2 moves in a direction perpendicular to the suction plate 12. By rotating the screw shaft 14 and the ball nut 15 integrally, the transport pad 2 is rotated in a plane parallel to the suction plate 12 around the screw shaft 14.

As shown in FIG. 3, an adhesive bar 16 having a length equivalent to or shorter than the length of one side of the suction plate 12 is provided at the edge of one side of the suction plate 12. The adhesive bar 16 is formed to be movable in a direction perpendicular to the suction plate 12. The adhesive bar 16 includes a support bar 16 a and an adhesive member 16 b bonded to the support bar, and is fixed to the actuator 17 so as to be replaceable.
The adhesive member 16b is not a member that is fixed semi-permanently, such as an adhesive, but is a member that temporarily adheres to a printed wiring board that is an object to be conveyed by a physical action, and lifts the printed wiring board. For example, it is composed of a urethane sheet.

The adhesive bar 16 is moved in a direction orthogonal to the suction plate 12 by the actuator 17. As shown in FIG. 4, the actuator 17 is constituted by, for example, an electric cylinder that moves the piston rod 17 a in the axial direction. An L-shaped member 17b is fixed.
The actuator 17 is formed in a substantially rectangular parallelepiped shape, for example, and the L-shaped member 17b has a shape along the bottom surface and one side surface of the actuator 17, and the L-shaped member 17b is moved in the axial direction of the piston rod 17a. Moves in the axial direction of the piston rod 17a using the side surface of the actuator 17 as a guide, and the L-shaped member 17b and the bottom surface of the actuator 17 are in contact with each other, thereby restricting the movement of the L-shaped member 17b.

  A support bar 16a of the adhesive bar 16 is fixed to the bottom of the L-shaped member 17b. Therefore, with the movement of the piston rod 17a in the axial direction, the adhesive bar 16 moves in a direction orthogonal to the suction plate. The actuator 17 is driven and controlled by the control device 21. The actuator 17 is formed so that the adhesive bar 16 can move in the direction of the surface opposite to the surface of the adhesive plate 16 where the adhesive member 16b faces the printed wiring board. In the state where the printed wiring board is sucked and held on the suction plate 12, the actuator 17 has the adhesive bar 16 on the opposite side of the surface where the adhesive member 16 b faces the printed wiring board of the suction plate 12. The movement of the printed wiring board is restricted by the suction plate 12 by moving it to a position that is positioned in the surface direction, so that the printed wiring board and the adhesive member 16b are separated.

  As shown in FIG. 3, an anti-slip member 18 is provided on the inner side of the side of the suction plate 12 where the adhesive bar 16 is provided and on the edge of one side adjacent to this side. The anti-slip member 18 is conveyed while the printed wiring board in the state of being sucked and held by the suction plate 12 is rotated on the suction plate 12 as the suction fan 11 rotates, and the printed wiring board is sucked and held. By moving the pad 2 at a relatively high speed, the printed wiring board is prevented from moving on the suction plate 12 due to inertia. The anti-slip member 18 may be any member that can prevent movement due to rotation of the suction fan 11 by friction between the anti-slip member 18 and the printed wiring board, for example, acrylic, urethane, rubber, etc. It is composed of copolymer foam.

  The anti-slip member 18 is located at least near the corner A of the two sides of the suction plate 12 where the adhesive bar 16 is provided, for example, the corner A shown in FIG. It is arranged including the part. Relative positional relationship between the printed wiring board and the transport pad 2 when the printed wiring board is held by suction so that the corner of the suction board 12 near the corner A and the portion near the corner of the printed wiring board face each other. Regardless of the size and shape of the adhesive bar 16 and the edge of one side of the printed wiring board while preventing the movement of the printed wiring board on the suction plate 12, regardless of the size and shape Can be adhered.

  Further, in the vicinity of the corner portion A of the suction plate 12, one or more pushers 19 for releasing the printed wiring board sucked by the suction plate 12 are provided as shown in FIG. The pusher 19 includes, for example, a solenoid shaft. The pusher 19 is normally maintained in a state in which the solenoid shaft does not protrude from the surface of the suction plate 12 facing the printed wiring board, and the solenoid shaft is moved in the direction of the printed wiring board by a magnetic attraction force. Passes through a through hole 12b (shown in FIG. 3) formed in the suction plate 12, protrudes toward the printed wiring board, and forms a gap between the printed wiring board sucked and held by the suction plate 12 and the suction plate 12. . As a result, the printed wiring board being held by suction is separated from the suction plate 12 while generating a suction force.

The support plate 13 includes a distance sensor 20 configured by a laser sensor or the like for detecting a distance between a surface of the suction plate 12 facing the printed wiring board and an object existing at a position facing the printed wiring board. Is provided.
The detection signal of the distance sensor 20 is input to the control device 21 as shown in FIG. The control device 21 controls the arms 4 and 5, the actuator 17 that controls the adhesive bar 16, and the pusher 19 based on various sensors (not shown) that detect the positions of the arms 4 and 5 and the detection signal of the distance sensor 20. The printed circuit board, which is the object to be transferred, is sucked and held by the transfer pad 2 one by one from the transfer source location to the transfer destination location.

FIG. 7 is a flowchart illustrating an example of a processing procedure when the printed wiring board is conveyed in the control device 21.
First, as an initial process (step S1), the control device 21 sets a target position in a plane parallel to the suction plate 12 of the transport pad 2 at the place where the printed wiring board is transported and a transport destination of the printed wiring board. The target position in the plane parallel to the suction plate 12 and in the direction perpendicular to the suction plate 12 of the transport pad 2 at the mounting position is set. This setting is performed by an operator performing an input operation. Subsequently, the control device 21 starts reading the detection signals of the distance sensor 20 and various sensors at a constant cycle. Also, the suction fan 11 is activated.

  Next, the control apparatus 21 moves the conveyance pad 2 to the target position which is a conveyance origin based on the detection signal of various sensors. Further, based on the detection signal of the distance sensor 20, the distance between the printed wiring board and the suction plate 12 is set to a predetermined distance without bringing the transport pad 2 into contact with the printed wiring board and the suction plate 12. Move to the position (step S2). The predetermined distance between the printed wiring board and the suction plate 12 is such that the printed wiring board is transported by the suction force of the suction fan 11 when the transport pad 2 is brought close to the printed wiring board with the suction fan 11 activated. The distance is not attracted to the pad 2 and is set to a distance at which the printed wiring board can be attracted and held by the transport pad 2 by lifting the printed wiring board by an adhesive bar 16 described later.

  Next, the position of the transport pad 2 is left as it is, and only the adhesive bar 16 is moved to the printed wiring board side, and the adhesive member 16b is brought into contact with the printed wiring board to adhere the printed wiring board to the adhesive member 16b. Subsequently, the adhesive bar 16 is moved on the side opposite to the printed wiring board, that is, in a direction in which the printed wiring board approaches the suction plate 12 (step S3). At this time, since the suction fan 11 is in operation, if the distance between the printed wiring board adhered to the adhesive bar 16 and the suction plate 12 becomes narrower as the adhesive bar 16 moves in the direction of the suction plate 12, The printed wiring board is attracted to the suction plate 12. At this time, the predetermined distance between the printed wiring board and the transport pad 2 is such that the printed wiring board is not attracted to the suction plate 12 when the transport pad 2 is brought close to the printed wiring board in a state where the suction fan 11 is operated. Therefore, the printed wiring board located under the printed wiring board adhered to the adhesive bar 16 is not easily attracted to the transport pad 2. That is, it is avoided that a plurality of stacked printed wiring boards are attracted to the transport pad 2.

  Subsequently, the control device 21 moves the transport pad 2 to the target position, which is the transport destination of the printed wiring board, with one printed wiring board being sucked and held by the transport pad 2, and the suction plate 12 and the printed board. The distance from the target position of the wiring board is moved to a position where the distance is a predetermined distance (step S4). The predetermined distance between the printed wiring board and the transport pad 2 at this time is a state in which the suction fan 11 is operated and a printed wiring board sucked and held by the transport pad 2, which will be described later, is released by the pusher 19, The distance is set so as not to give an impact to the printed wiring board when the printed wiring board falls.

  Next, the rotational speed of the suction fan 11 is controlled to reduce it to a certain suction force, and the pusher 19 is operated to cause the solenoid shaft of the pusher 19 to protrude toward the printed wiring board (step S5) and is held by suction. The printed wiring board is pressed by the pusher 19 to form a gap between the printed wiring board and the suction plate 12. Due to the gap, the force for sucking the printed wiring board is weakened, the printed wiring board cannot be sucked and held, and the printed wiring board is released. That is, the printed wiring board is placed at the target position of the transport destination.

In a state where the printed wiring board is sucked and held by the suction plate 12, the adhesive bar 16 is moved in the direction opposite to the surface facing the printed wiring board of the suction plate 12, and the adhesive member 16b. And the printed wiring board are in a detached state. Therefore, by pressing the printed wiring board held by suction with the pusher 19 and creating a gap between the printed wiring board and the suction board 12, the adhesive force by the adhesive member 16b acts on the printed wiring board. In addition, the printed wiring board is easily detached from the suction plate 12.
When all the predetermined printed wiring boards have not been transported (step S6), the rotational speed of the suction fan 11 is controlled to return the suction force to a predetermined magnitude, and the process returns to step S2 to transport the pad 2 Is moved to the target position, which is the transport source of the printed wiring board, and the next printed wiring board is transported to a predetermined transport destination in the same procedure as described above. When the predetermined number of printed wiring boards have been transported, the suction fan 11 is stopped and the process is terminated (step S7).

<Effect of this embodiment>
This embodiment has the following effects.
When the transport device 1 according to the embodiment of the present invention sucks and holds the printed wiring board by the transport pad 2, the distance between the transport pad 2 and the printed wiring board is determined by the suction force of the transport pad 2. First, the printed wiring board is transported by lifting the printed wiring board with an adhesive bar 16 having an adhesive strength that can temporarily lift the printed wiring board while keeping the board at a distance that cannot be adsorbed. After moving to a position where the suction force of the pad 2 can be sucked, the printed wiring board is sucked by the suction force of the transport pad 2. Since the transport pad 2 is in a position where the printed wiring board cannot be sucked by the suction force, the printed wiring board under the printed wiring board lifted by the adhesive bar 16 is not sucked together. The printed wiring board adsorbed to the transport pad 2 is only the printed wiring board lifted by the adhesive bar 16. That is, it can be avoided that a plurality of printed wiring boards are simultaneously attracted to the transport pad 2.

  Further, when releasing the printed wiring board being held by suction, the pusher 19 is operated to provide a gap between the suction board 12 and the printed wiring board so as to weaken the suction force to the printed wiring board. Here, when the suction force is weakened by controlling the suction force of the suction fan 11, for example, by stopping the suction fan 11, the number of rotations of the suction fan 11 decreases until the suction fan 11 stops. However, it takes time for the suction force to weaken. Further, if the suction fan 11 is repeatedly stopped and started, a failure or the like is likely to occur accordingly.

  In the transport device 1, the suction fan 11 remains in an operating state, and the printed wiring board is released while a certain amount of suction force is generated. As a result, each printed wiring board is set in a predetermined state while the suction fan 11 is in an operating state from when the conveying device 1 is started to when it is stopped, including when the printed wiring board is sucked and when the printed wiring board is released. Can be transported to other transport destinations. Since it is possible to prevent the suction fan 11 from repeatedly starting and stopping, it is possible to reduce a failure or the like occurring in the suction fan 11 by repeating the starting and stopping.

Further, a pusher 19 is provided in the vicinity of the corner A, and the printed wiring board and the transport pad 2 are arranged so that the corner of the printed wiring board is in the vicinity of the corner A as a guide. For this reason, the vicinity of the corner of the printed wiring board is positioned in the vicinity of the pusher 19. As a result, regardless of the shape and size of the printed wiring board, the printed wiring board can be arranged so that the pusher 19 and the printed wiring board face each other. Even if only one pusher 19 is provided, the printed wiring board can be arranged. A gap can be formed between the suction plate 12 and the printed circuit board.
In addition, since the adhesive bar 16 is provided only on one side of the transport pad 2, one side of the two opposite sides of the printed wiring board is stacked on the printed wiring board only on the other side. Is lifted. Therefore, only one printed wiring board can be reliably adsorbed to the transport pad 2 while suppressing the adhesive force required to lift one printed wiring board.

  Moreover, since the adhesive bar 16 is provided over the entire side of the transport pad 2, even when the shape or size of the printed wiring board is changed, by adhering to the adhesive bar 16, By setting the positional relationship between the adhesive bar 16 and the printed wiring board so that the printed wiring board can be lifted, a plurality of printed wiring boards can be conveyed simultaneously regardless of the size of the printed wiring board. Can be avoided. Further, the position adjustment of the adhesive bar 16 and the printed wiring board should be adjusted so that the corner of the printed wiring board and the vicinity of the corner A portion of the suction plate 12 face each other, and high-precision adjustment is necessary. There is no rough adjustment. Therefore, even if the printed wiring board is changed to another printed wiring board having a different shape, size, etc., it is only necessary to roughly adjust the positional relationship between the transport pad 2 and the printed wiring board placed on the transport source. Subsequently, it can be avoided that a plurality of printed wiring boards are conveyed simultaneously. That is, even if the printed wiring board is changed, the conveyance can be continued without significantly adjusting the conveyance device 1. In particular, when a plurality of types of printed wiring boards are transported or the like, it is not necessary to make a large adjustment every time the printed wiring boards are switched.

  Further, since the printed wiring board is sucked by the suction fan 11 in the transport pad 2, the printed wiring board is the suction board 12 depending on the magnitude of the frictional force between the suction board 12 and the printed wiring board. The printed wiring board moves on the suction plate 12 while being sucked and held, and the printed wiring board moves similarly on the suction plate 12 by moving the transport pad 2 at high speed. There is a case. Depending on the positional relationship between the suction fan 11 and the printed wiring board, if the printed wiring board moves on the suction plate 12, the suction force may be insufficient, and the printed wiring board may be released during conveyance. However, since the conveyance device 1 is provided with the anti-slip member 18 on the suction plate 12, it is possible to prevent the printed wiring board from moving on the suction plate 12.

<Modification>
In the above-described embodiment, when the printed wiring board is released at the conveyance destination, the conveyance pad 2 is stopped at a position away from the target position where the printed wiring board is placed by a predetermined distance, and in that state, the pusher 19 Although the case where the printed wiring board is dropped by pressing the printed wiring board has been described, the present invention is not limited to this. For example, in a state where the printed wiring board held by suction is in contact with the target placement location, while the printed wiring board is pressed by the pusher 19, the transport pad 2 is moved in the opposite direction to the printed wiring board, The printed wiring board may be detached from the conveyance pad 2 without giving an impact to the printed wiring board by moving only the conveyance pad 2 while being placed on the placement place.

Moreover, in the said embodiment, although the case where the adhesive member 16b was continuously provided in the adhesive bar 16 was demonstrated, the adhesive member 16b does not need to be provided continuously and partially. It may be provided, and in short, it may be arranged in any manner as long as an adhesive force capable of temporarily lifting the conveyance target can be obtained.
Further, the adhesive member 16b is not limited to the urethane sheet, and may be, for example, a sucker sheet. Such a material may be used.

Moreover, the anti-slip | skid member 18 which generate | occur | produces frictional force between printed wiring boards may be provided partially, and may be provided continuously. Further, the anti-slip member 18 is not limited to the case where the anti-slip member 18 is provided at the edge of the conveyance pad 2, and may be provided at a portion predicted to contact the conveyance object. What is necessary is just to be arrange | positioned in the position which can suppress that a target object moves on the adsorption | suction board 12. FIG.
Moreover, although the case where the four suction fans 11 were provided was demonstrated in the said embodiment, the number and arrangement position of the suction fans 11 should just be set arbitrarily. For example, depending on the shape and size of the printed wiring board to be transported by the transport device 1, any shape and size of the printed wiring board can be sucked and held by the transport pad 2. The number of suction fans 11 that can generate suction force may be provided, and the arrangement position thereof may be similarly determined.

  At this time, the number of suction fans that can securely hold the printed wiring board and transport it to the transport destination based on the shape and size of the printed wiring board and the suction force of each suction fan 11. 11 and the remaining suction fans 11 may remain stopped, and a sufficient suction force is applied to the printed wiring board in accordance with the shape and size of the printed wiring board and the position of the suction fan 11. You may make it drive only the suction fan 11 arrange | positioned in the position which can emit. In this way, the power consumption can be reduced by changing the suction fan 11 driven according to the type of the printed wiring board and the control state thereof.

In the above embodiment, the case where the suction force is generated by the suction fan 11 has been described. However, the present invention is not limited to this. For example, a blower may be used instead of the suction fan 11. Any device capable of generating can be applied.
In the above-described embodiment, the case where only one pusher 19 is installed has been described. However, the present invention is not limited to this, and a plurality of pushers 19 may be provided. What is necessary is just to set a location.

Moreover, in the said embodiment, although the case where a printed wiring board was conveyed as a conveyance target was demonstrated, it is not restricted to this, The plate-shaped member which is mounted in the laminated state and picks up one by one and conveys If so, it can be applied.
Moreover, in the said embodiment, although the case where the printed wiring board laminated | stacked on the mounting place of the conveyance origin was demonstrated, it is not restricted to this, For example, the line conveyed by lines, such as a belt The present invention can be applied even when the upper plate member is moved to another line. For example, even when the belt or the like is made of a relatively soft and light member, when the printed wiring board is moved to another line, it is possible to avoid the belt from being adsorbed simultaneously with the printed wiring board. it can.

Moreover, in the said embodiment, the conveying apparatus 1 may be mounted in the rack etc. with a caster. By configuring the transfer device 1 to be movable in this manner, for example, the transfer device 1 can be easily moved to a required location according to a work process. Particularly in a printed wiring board production line or the like, there are many work processes, and many printed wiring boards are often moved from one line to another. Therefore, by configuring the transport apparatus 1 to be movable, the transport apparatus 1 can be used effectively, and the operating efficiency of the transport apparatus 1 can be improved.
It should be noted that the scope of the present invention is not limited to the illustrated and described exemplary embodiments, but includes all embodiments that provide the same effects as those intended by the present invention. Further, the scope of the invention can be defined by any desired combination of particular features among all the disclosed features.
