Description

  In the present invention, a rectangular plate-like workpiece (hereinafter referred to as “work”) having been processed is set to a vertical direction (the thickness direction is a horizontal direction) (hereinafter referred to as “standing”). The present invention relates to a processing apparatus provided with a loading / unloading apparatus for loading / unloading.

  Hereinafter, a conventional technique will be described with reference to the drawings. FIG. 8 is a left side view of the processing apparatus 100 including the carry-in / carry-out apparatus of Patent Document 1. The slider 1 sucks and holds the workpiece w whose surface has been processed by the lifter 2, moves from the back side to the near side of the page, and moves the workpiece w to the standby position (the workpiece placement surface is horizontal) on the rotary table 3. Placed on. When the work w on which the rotary table 3 is placed is held by a clamper provided on the rotary table 3 (not shown), the slider 1 moves to a position where it does not interfere with the rotary table 3. When the slider 1 moves to a position where it does not interfere with the rotary table 3, the rotary table 3 rotates 90 degrees counterclockwise (operating position) with the workpiece w held by the clamper to stand the workpiece w in the vertical direction. The hanger 4 holds a work w on the rotary table 3 by closing a clamper (not shown) provided on the hanger 4. When the workpiece w is held on the hanger 4, the clamper provided on the rotary table 3 releases the holding state of the workpiece w, and then rotates 90 degrees clockwise to return to the standby position. When the rotary table 3 returns to the standby position, the hanger 4 is lowered and the work w is stored in the storage portion of the stocker 5. The stocker 5 in which the work w is stored in the storage portion is positioned at a position where the next empty storage portion faces the hanger 4. When a predetermined number of works w are stored in the stocker 5, the stocker 5 is rotated 180 degrees in the horizontal direction by the turntable 6 which can be moved up and down. Then, the work w stored in the stocker 5 is moved to the processing table by the reverse procedure to the above, and the back surface of the work w is processed. According to this processing apparatus 100, since it is not necessary to provide a reversing device for reversing the workpieces w one by one or collectively, the entire apparatus can be reduced in size. Moreover, since both surfaces of the workpiece w can be processed continuously, the processing efficiency could be improved.

  Here, the work introduction part to the stocker 5 of the processing apparatus 100 will be further described. 9 is a detailed cross-sectional view of a portion B in FIG. 8, FIG. 10 is a view taken along arrow C in FIG. 9, and FIG. 11 is a plan view of the workpiece w. As shown in FIG. 11, the workpiece w is provided with a non-working region En around a working region Ek indicated by hatching. In the case of the illustrated workpiece w, the width fu of the non-processed area on the side held by the clamper (the upper side in the longitudinal direction) is larger than the width f (usually about 15 mm) of the other non-processed areas.

As shown in FIG. 9, the pedestal 20 of the loading / unloading apparatus is fixed to the bed of the processing apparatus 100 and is integrated with the processing apparatus 100.
The rotary table 3 includes a rotary plate 3a and a mounting table 3b fixed to the rotary plate 3a. The mounting table 3b is provided with a clamping means (not shown) for clamping the workpiece W. The rotary table 3 is rotatable around a shaft 6 supported at both ends by the pedestal 20. The rotary table 3 is rotatable within a range of 90 degrees from the horizontal position (standby position) indicated by the solid line on the surface 3bs of the mounting table 3b to the vertical position (operation position). The length L of the mounting surface of the mounting table 3b is equal to the length of the longest workpiece, and the X coordinate (left and right direction in the drawing) of the end on the shaft 6 side is the same as the X coordinate of the center of the shaft 6. In order to ensure the vertical positioning of the clamper of the hanger 4 and because the same rotary table 3 is used for the workpiece w having a different length, the position of the clamper in the standby state (ascending end) is not changed. Then, the end portion of the workpiece w held by the clamper (hereinafter referred to as “upper end”) is always positioned at the same position regardless of the length of the workpiece w. Therefore, in the case of the longest workpiece, the XZ coordinate (the left-right direction in the drawing) of the end on the shaft 6 side (hereinafter referred to as “lower end”) is the same as the X coordinate of the center of the shaft 6. Hereinafter, the X-axis direction is referred to as the front-rear direction, the right side in FIG. 9 is referred to as the front, and the left side is referred to as the rear.

  A surface 3ai is formed at the rear end of the rotating plate 3a. Here, when the surface including the surface 3bs of the mounting table 3b when the rotating table 3 is positioned at the operating position is referred to as “reference surface A”, the surface 3ab of the rotating table 3 at the standby position is opposed to the reference surface A. However, it is configured to be separated from the reference plane A by about 5 mm except for the portion facing the clamper. V-shaped guide grooves 5a connected to the work holding grooves 5h are formed on both upper sides in the Y direction of the stocker 5. The workpiece holding grooves 5h are arranged at various intervals such as 16 mm, 18 mm, and 25 mm in the X direction depending on the workpiece type.

  When the turntable 3 is in the standby position, a roller 7 that is rotatable around the shaft 8 is disposed at a position facing the surface 3ab across the reference surface A. Here, referring to FIG. 10, when a vertical surface including the center line in the width direction (Y direction) of the rotary table 3 is a surface Mo, the roller 7 has a front end 7 a separated from the reference surface A by about 5 mm, In the Y direction, the length of the end surface 7i on the side close to the surface Mo does not exceed the non-working area En of the workpiece W facing the front end 7a. In the Z direction, the Z coordinate of the rotation center is the lower end of the surface 3ai. It is supported on both the left and right sides of the opening 20a of the base 20 so as to be the same.

Between the rotary table 3, the roller 7 and the stocker 5, two sets of rollers 9 </ b> F and 9 </ b> B that are rotatable around the shaft 10 are arranged. The rollers 9F and 9B have end portions 9Fa and 9Ba on the side close to the reference plane A in the X direction at a distance of 2 to 3 mm in the X direction from the reference plane A, and the Y direction in the side close to the surface Mo. The end faces 9Ri and 9Li are rotatably supported on both the left and right sides of the opening 20a so as not to exceed the opposing non-working regions.
The height of the work storage portion of the stocker 5 is determined such that the upper end of the longest work w is the height of the upper end surface 5s of the stocker 5. When a workpiece w having a short length is stored, a spacer having a thickness equal to the difference between the length of the workpiece and the length of the longest workpiece is previously stored in the stocker 5 at the bottom of the stocker 5. The height of the upper end of the workpiece w is always the same.

  The plate | board thickness of the workpiece | work w is 0.1-1 mm. When the clamping state by the clamping means on the mounting table 3b is released, the workpiece w held by the hanger 4 by the clamping means provided on the hanger 4 can freely move in the X direction. Since it has the rigidity which can become independent without bending inside, the lower end does not swing in the X direction. Further, even when the lower end of the workpiece w was swung in the X direction for some reason, the lower end of the workpiece w could be guided to the guide groove 5a by the rollers 9F and 9B.

  In recent years, the number of printed circuit boards has been increased, and a workpiece w having a thickness exceeding 2 mm has been put into practical use. In a multi-layer printed circuit board, warping due to the manufacturing process often occurs. For example, in the case of a printed circuit board having a length of 600 mm, both ends in the length direction are centered as shown in FIG. There is a workpiece w that warps about 30 mm. For example, when the length of the workpiece w is L and the rotary table 3 is in the standby position, the lower end of the workpiece w held by the clamper provided on the hanger 4 is positioned between the surface 3ab and the roller 7. Therefore, even after the rotary table 3 is moved to the standby position, the lower end of the work w is between the surface 3ab and the roller 7, so that the work w can be easily inserted into the stocker 5. However, among the workpieces w having a short length, when the rotary table 3 is in the standby position due to the warp of the workpiece W or the like, the lower end of the workpiece w held by the clamper of the hanger 4 is the surface 3ab and the roller 7. There are things that fall out of between. In such a case, not only the workpiece w having a large warp cannot be inserted into the stocker 5, but also the workpiece w, the roller 7 or the rotary table 3 may be damaged by lowering the hanger 4.

  An object of the present invention is to provide a machining apparatus that can be smoothly housed in the stocker 5 even if the workpiece w has warped.

  In order to solve the above-described problems, the present invention provides a rotary table having a horizontal direction as a standby position and a vertical direction perpendicular to the horizontal direction as an operating position, and a moving means that holds the upper end of the workpiece and is movable in the vertical direction. A first guide device provided with a guide surface in a processing device in which a horizontal work piece is stood in a vertical direction by the rotary table and the work piece is stowed by the moving means. And a rotating device that supports a second guide device having a guide surface and positions the supported second guide device at a predetermined first position and a second position in a horizontal plane, The first guide device is disposed so as to face the work placing surface of the rotary table, the guide surface being positioned at the operating position, with a predetermined distance therebetween, and the rotating device is The position of 1 is a position where the guide surface sandwiches the workpiece on which the second guide device stands in a vertical direction and faces the first guide device at a predetermined distance, and the second position is: The second guide device is disposed at a position where it does not interfere with the rotary table, and the workpiece is guided in the vertical direction by the guide surfaces of the first guide device and the second guide device. It is characterized by.

  In this case, it is more effective if a linear guide device is provided between the second guide device and the rotating device, and the second guide device is configured to be movable in the linear direction.

  It is more effective if a plurality of rotating bodies (rollers or spheres) having the same diameter are aligned in the vertical direction, and a plane including all the apexes of the rotating bodies is used as the guide surface.

  Even if the workpiece W is warped, the workpiece W can be smoothly stored in the stocker 5 without damaging the workpiece W, the roller 7 or the rotary table 3.

The bearing 30b is fixed to the lower portion of the guide 13L so that the surface 13Ra is perpendicular to the moving direction. The guide 13R (not shown) is symmetric with respect to the surface Mo. The guide 13R and the guide 13L can be reciprocated and positioned on the track 30a by a driving device (not shown). The distances between the surfaces 13Ra and 13La and the rotation centers O1r and O1l of the rotary actuators 14R and 14L are p, and the distances from the reference plane A of the rotation centers O1r and O1l are (q + c). The standby positions of the guide 13R and the guide 13L are positions where the surface 13Ra and the surface 13La are at a distance p from the rotation center of the rotary actuators 14R and 14L, as in the first embodiment.

Next, the operation of this embodiment will be described.
Procedure A: Procedures 1 to 4 in the first embodiment are performed in order.
Procedure B: The rotary actuators 14R and 14L are operated to rotate the guide 13R and the guide 13L at the standby position by 90 degrees.
Procedure C: A driving device (not shown) is operated, and the guide 13R and the guide 13L are positioned at operating positions (as shown by arrows in FIG. 3, they are moved toward the surface 11Ra and the surface 11La by a distance c). Then, the distances between the surfaces 13Ra and 11Ra of the guide 13R and the surfaces 13La and 11La of the guide 13L are the same distance mb as in the first embodiment, and the left turn of the workpiece w is the second guide.

That is, the surface B is the same surface as the surface 11Ra of the right guide device 11R in the first embodiment. Similarly, the surface in contact with the rear end of all the rollers 16 supported by the right guide device 15L is the same surface as the surface 11La of the right guide device 11L.

The second guide device 18 includes a right guide device 18R and a right guide device 18R and a left guide device 18L that is different from the right guide device 18R.
