Abstract

PURPOSE:To attach bar code labels in four different directions by a method wherein an attaching head holding bar code labels thereon is made switchable between two label attaching directions, i.e., reference position and an angular displacement of 90 deg. and the bar code is printed in two directions, regular and reverse. CONSTITUTION:When bar code label is attached at an angle of zero to the reference direction of a base plate, a system controller 234 gives instructions to a bar code printer 6 to print the designated bar code from left to right (regular rotation). When a bar code label is attached at an angle of 90 deg. to the reference direction of the base plate, the system controller 234 prints the designated bar code from left to right (regular rotation). When bar code label is attached at an angle of 180 deg. to the reference direction of the base plate, the system controller 234 prints the designated bar code from right to left (reverse rotation). When bar code label is attached at an angle of 270 deg. to the reference direction of the base plate, the system 234 prints the designated bar code from right to left (reverse rotation).

Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to an apparatus for attaching an identification barcode label to a workpiece such as a printed circuit board in a pre-stage of a component mounting process on a printed circuit board.

<Prior Art> In recent processes for mounting electrical components on printed circuit boards, barcode labels representing mounting specifications are sometimes pasted on the boards in order to manage the mounting specifications for each board. In the mounting process, components are mounted according to the board by reading barcode labels on the board.

Incidentally, the position where the barcode label is attached on the substrate and the direction in which the barcode label is attached are usually specified depending on each substrate. Normally, the pasting direction of the barcode label is relative to the reference direction of the board.
One of four directions, 0°, 90°, 180°, and 270°, is set.

Conventionally, in order to separate barcode labels in four directions, a label attaching head that suctions and holds a barcode label is configured to be rotatably displaceable in four directions.

<Problems to be Solved by the Invention> However, the conventional example having such a configuration has the following problems.

In other words, since the label pasting head is connected to a suction tube for suctioning and holding the barcode label, it is difficult to rotate the pasting head itself in four directions. There were problems such as the peripheral mechanisms becoming complicated and rotational malfunctions occurring.

The present invention has been made in view of these circumstances, and provides a barcode label pasting device that can paste barcode labels in four directions without complicating the configuration of the label pasting head. is intended to provide.

<Means for solving UIB> In order to achieve such an object, the present invention has the following configuration.

That is, the present invention includes a barcode printer, a barcode pasting mechanism for receiving a barcode label fed out from the barcode printer and pasting it onto a workpiece, and combining the barcode pasting mechanism with a barcode printer. Movement a to move to the predetermined barcode pasting position
m, and a workpiece conveyance m mechanism for transporting a workpiece to which a barcode label is pasted to the barcode pasting position, wherein the barcode labeling device is attached to the barcode pasting mechanism, a pasting head that can be switched between two positions, a reference position and a 90° rotational displacement position while holding a label; a rotation angle control means for controlling a rotation angle of the pasting head; and a barcode printer. On the other hand, the present invention includes printing direction control means for specifying the direction of printing the barcode in the forward direction or in the reverse direction of the barcode label.

<Effect> The effects of the present invention are as follows.

According to the present invention, barcode labels can be pasted in four directions depending on the combination of the printing direction of the barcode label and the position of the pasting head.

For example, if you print a barcode label in normal rotation and set the pasting head position to the reference position, the pasting position of the barcode label will be 0°, and if you print the barcode label in normal rotation and set the pasting head position to If the position is set to 90°, the barcode label pasting position will be 90°, and if the barcode label is printed in reverse and the pasting head position is set to the reference position, the barcode label will be pasted at 90°. If the pasting position of the barcode label is set to 18°, and the barcode label is printed in reverse and the pasting head position is set to 90°, the pasting position of the barcode label is 27°.
It becomes 0@.

When the movable member 28 is transferred, the air cylinder 4o is contracted and the movable member 28 is moved backward, and comes into contact with the stomper 52 attached to the rear end of the base plate 26 and stops.

When the label placement block 36 reaches the rear stop position P2, the rotary cylinder 54 attached to the base plate 26 is activated. A pusher member 56 is attached to the rotating shaft of the rotary cylinder 54. During the operation of transferring the barcode label BL to the label placement block 36, the pusher member 56 is in the retracted position as shown by the chain line in FIG. When the rotary cylinder 54 operates at the stop position P2, the button member 56 rotates approximately 90 degrees counterclockwise, and the label placement block 36

In addition, the reference numeral 58 in FIG. 4 is an optical sensor for confirming that the pusher member 56 is in the retracted position, and the reference numeral 60 is an adjuster for adjusting the height of the label placement block 36.

Next, the configuration of the pasting head section 10 will be explained with reference to FIGS. 8 to 10. FIG. 8 is a front view of the pasting head section 10, FIG. 9 is a side view thereof, and FIG. 10 is a partially cutaway view showing the rotational positioning mechanism of the pasting head.

The base member 62 of the pasting head section 10 is connected to the X-axis drive mechanism 12. An air cylinder 64 for raising and lowering the pasting head 66 is attached to this base member 62.
is installed. A pair of guide shafts 6B are slidably fitted into the base member 62 with their upper and lower ends connected by connecting plates 70 and 72.

By connecting the lower connecting plate 72 to the long door 4 of the air cylinder 64, the guide shaft 68 and the connecting plates 70, 72 are configured to move up and down as a unit by the expansion and contraction movement of the rod 74. .

A rotary cylinder 76 for rotationally displacing the pasting head 66 by 90 degrees is provided on the lower surface of the connecting plate 72, and a head support member 80 is attached to a rotating shaft 78 of the rotary cylinder 76. A pair of guide shafts 8 each having a compression spring 82 fitted into the head support member 80

The downward stroke of the air cylinder 64 is switched between large and small. When the rod 88 is contracted and the stopper 92 extends toward the head side, the contact member 94 located on the side of the rotary cylinder 76 contacts the tip of the stopper 92 when the air cylinder 64 is extended. In addition, the downward stroke of the air cylinder 64 is shortened so that the lower limit position of the pasting head 66 at this time substantially coincides with the label placement block 36 of the barcode label positioning section 8. Furthermore, when the rod 88 is extended and the stopper 92 is retracted, the downward stroke of the air cylinder 64 becomes longer, and as will be described later, the barcode label BL, which is suctioned and held by the pasting head 66, is moved onto the substrate. It is designed to descend to a position where it can be pasted upward.

The pasting head 66 according to this embodiment is configured to be rotatably displaced by 90 degrees by the above-mentioned rotary cylinder 76. Specifically, as shown in FIG. 10, the side surface of a substantially triangular rotating member 96 attached to the rotating shaft 78 of the rotary cylinder 76 touches a stopper 98 or 100 provided at a side position of the rotary cylinder 76. The attachment plate 66 is configured to be rotated by 90° upon contact.

A side plate 102 and a fixed frame 1.degree. 4 are erected in parallel on the main body frame 2, and a pair of screw shafts 106, 108 and guide shafts 110, 112 are installed between these members. A movable frame 114 is fitted into these screw shafts 106, 108 and guide shafts 1.10, 112. The screw shafts 106 and 108 transfer the rotational force of the motor 116 attached to the side plate 102 to the belts 118 and 120.
are rotated by being applied to each other via the . As a result, the movable frame 114 moves to the guide shaft 110.

The transport heald 124 is driven by a motor 130 (
(See Figure 15).

When the substrate W is transferred from the right side of FIG. 11 to the transfer rails 24, 126 by a loader (not shown), the substrate W is transferred to the left in the figure. When the substrate W reaches the barcode pasting position P, the stopper mechanism 132 shown in FIG. 14 is activated to receive the substrate W. This stopper mechanism 132
It consists of an air cylinder 134 fixedly installed above and a stop bar 136 attached to the rod.

A positioning mechanism 138 in the width direction of the substrate W as shown in FIG. 13 is provided at a position corresponding to the barcode pasting position fP of the movable frame 114. This positioning mechanism 138 has a puncher plate 146 attached to a rod 144 of an air cylinder 140 attached to the movable frame 114 via a member 142.
44, the substrate W received by the stopper 136 is laterally pressed against the fixed frame 104 side, thereby positioning the substrate W.

Next, the substrate support part 18 for supporting the substrate W from below when attaching a barcode label to the positioned substrate W will be described with reference to FIG. 16.

The substrate support portion 18 shown in FIG.
It is located on the main body pedestal 2 below the substrate W received by the board, and is composed of a plurality of substrate support mechanisms 148 and a mounting table 150 on which these are placed.

The mounting table 150 is made of a magnetic material such as iron, and has grid-like marked lines 152 engraved on its surface to serve as a guide for determining the mounting position of the substrate support mechanism 148.

If electrical components are already mounted on the back side of the board W transferred by the board transport mechanism 16, the operator uses the marked line 152 drawn on the mounting table 150 as a guide to bring each board support mechanism 148 into contact. Each board support mechanism 148 is positioned at a position where the member 160 does not touch the mounted components on the board. At this time, since the substrate support mechanism 148 is only attracted to the mounting table 150 by the magnet 156, the position of the substrate support mechanism 148 can be easily and quickly changed. When pasting a barcode label, the rod 158 of the air cylinder 154 of each substrate support mechanism 148 is driven to extend, and when each contact member 160 pushes up the substrate W from below, the side edge of the upper surface of the substrate W is Frame 10.4.

The air cylinder 6 of the pasting head 10 has been moved to a predetermined position above the substrate W by the shaft drive mechanism 14.
40 rods 74 are driven to extend. At this time, since the stroke adjustment stopper 92 has been retracted, the pasting head 66 descends until the upper connecting plate 70 comes into contact with the damper 101 and stops as a buffer. At this lowered position, the lower surface of the pasting head 66 comes into contact with the surface of the substrate W, and the barcode label that has been suctioned and held by the pasting head 66 is pasted onto the substrate W.

A pulley 194 is fixed to a shaft 180 that rotatably supports the side plate 172, and the rotational force of a rotary cylinder 196 provided at the center of the side plate 172 is transmitted to the pulley 194 via an endless belt 198. Accordingly, the fixed frame 178 and the movable frame 188 are configured to be integrally driven by half a rotation.

The fixed frame 178 and the movable frame 18B are each provided with a transport heald mechanism having the following configuration on their inner surfaces. As shown in FIG. 18, below both inner ends of the fixed frame 178, there are pulleys 202 and 204 on which an endless conveyor belt 200 is installed, and the pulley 202 is driven by a motor 206. On top of this conveyor belt 200, another conveyor belt 208 is connected to a pulley 210.

The system controller 234 is the host computer 2
Based on the label pasting specification information given from 32, the printing direction of the barcode and the angular position of the pasting head 66 are set as follows, depending on the pasting direction of the barcode label.

(1) When the label pasting direction is 0° (see FIG. 22(a)) When pasting a barcode label at an angle of Oo with respect to the reference direction of the board, the system controller 234 A command is given to the barcode printer 6 to print from left to right (forward rotation). The barcode label printed in this direction is suction-held by the pasting head 66 of the pasting head section 10 via the barcode label positioning section 8, and is transported to the barcode label pasting position. Subsequently, the system controller 234 moves the rotary cylinder 76 (see FIGS. 8 and 9) so that the displacement angle of the pasting head 66 becomes Oo.
After this is controlled, pasting of the barcode label is performed. Thereby, the barcode label is attached to the substrate at an angle of 0° with respect to the reference direction.

(2) When the label pasting direction is 90° (22nd
(See Figure (b)) When pasting a barcode label at an angle of 90° with respect to the reference direction of the board, the system controller 234
A command is given to the barcode printer 6 to print the designated barcode from left to right (forward rotation). The barcode label printed in this direction is suction-held by the pasting head 66 and transported to the barcode label pasting position, as in the case (1) above. Subsequently, the rotary cylinder 76 is controlled by the system controller 234 so that the displacement angle of the pasting handle 6 becomes 90 degrees, and then the bar code label is pasted.

This allows the barcode label to be placed at 90 degrees with respect to the reference direction.
It is attached to the substrate at an angle of 0°.

(3) When the label pasting direction is 180° (second
(See Figure 2 (C)) When pasting a barcode label at an angle of 180° with respect to the reference direction of the board, the system controller 234 prints the specified barcode from right to left (reversely). A command is given to the code printer 6. The barcode label printed in this direction is suction-held by the pasting head 66 and transported to the barcode label pasting position, as in the case (1) above. Subsequently, after the rotary cylinder 76 is controlled by the system controller 234 so that the displacement angle of the pasting head 66 becomes 0°, pasting of the barcode label is performed.

This makes the barcode label 1
It is attached to the substrate at an 80° angle.

(4) When the label pasting direction is 270° (second
(See Figure 2(d)) When pasting a barcode label at an angle of 270° with respect to the reference direction of the board, the system controller 234 prints the specified barcode from right to left (reversely). A command is given to the code printer 6. The barcode label printed in this direction is suction-held by the pasting head 66 and transported to the barcode label pasting position, as in the case (1) above. Subsequently, after the rotary cylinder 76 is controlled by the system controller 234 so that the displacement angle of the pasting head 66 becomes 90'', pasting of the barcode label is performed.

This makes the barcode label 2
It is attached to the substrate at a 70° angle.

In the above-described embodiment, the barcode label positioning section 8 for positioning the barcode label is provided separately from the pasting head section 10, but a positioning pin is provided on the pasting head 66 of the pasting head section 10. If this is installed, it is also possible to directly position the barcode label fed out from the barcode printer 6 with the pasting head 66 and hold it by suction.

Further, in the embodiment, the substrate reversing section 20 is provided at the rear stage of the substrate transport mechanism 16, but the substrate reversing section 20 may be arranged at the front stage of the substrate transport mechanism 16.

Further, in the embodiment, a printed circuit board is used as an example of a workpiece to which a barcode label is attached, but the present invention can be applied to other workpieces.

<Effects of the Invention> As is clear from the above description, according to the present invention, the pasting head that holds the barcode label is aligned with the reference position.
Since it is configured so that it can be switched between two directions at the 0° rotational displacement position, and the barcode printing direction can be switched between forward and reverse directions, the combination of both allows the barcode label to be printed in four directions. It can be pasted in different directions. Therefore, it is not necessary to configure the pasting head itself so that it can be switched in four directions, unlike the conventional apparatus, and the pasting head can be constructed accordingly.
