Abstract

PURPOSE:To obviate the need for a troublesome operation such as replacing reel by a method wherein individual bar code printing data is fed into a bar code printer for each work and the bar code to be printed is automatically varied responding to changes in the work specifications. CONSTITUTION:A printed bar code label is sent to the next bar code reader in order to read its bar code. The data thus read is sent to a system controller 234 to verify whether or not the data agrees with the corresponding bar code printing data. If a normal printing is indicated by the agreement between these two data, the bar code label is fed onto a peeling-off plate 32, positioned by a bar code label positioning part, held by suction on an attaching head part, transferred to a bar code label attaching position and attached to a predetermined place on a base plate.

is driven by a motor 128 (see FIG. 14), and the transport heald 124 is driven by a motor 130 (see FIG. 15).

When the substrate W is transferred from the right side of FIG. 11 to the conveyor bells 124 and 126 by a loader (not shown), the substrate W is conveyed 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 is composed of an air cylinder 134 fixed on the main body frame 2 and a stomper 136 attached to the rod thereof.

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 fiP of the movable frame 114. This positioning mechanism 138 has a pusher plate 146 attached to a rod 144 of an air cylinder 140 attached to the movable frame 114 via a member 142, and when the rod 144 extends, the substrate W held by the stopper 136 can be moved.

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.
No. 4 rod 74 is 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 At this time, since the stroke adjustment stopper 92 has been retracted, the pasting head 66 descends until the upper connecting plate 70 comes into contact with the damper 101 and stops as a buffer.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 the 20-bottom position 1, 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.

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 188 are each provided with a conveyor belt 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.

Next, with reference to FIG. 21, a schematic configuration of the control system of the barcode label pasting apparatus according to this embodiment will be described.

In the figure, reference numeral 230 is a process control computer that controls the production control of the process, and the host computer 232 of the barcode label pasting device and the host computer of the mounting process are
It gives the specification information of the processing board and receives the processing status of the board from each host computer. The host computer 232 of the barcode label pasting device determines the type of barcode label to be pasted on each board and the pasting of the barcode label on the board based on the board specification information given from the process control computer 230. Determine labeling specifications such as location. Label pasting specification information for each board is given to the system controller 234 of this device. The system controller 234 provides barcode printing data to the barcode printer 6 based on the label pasting specification information, and provides the XY axis drive mechanism 12 with barcode printing data.
14 to move the pasting head section 10 to a predetermined barcode pasting position, and control each unit in the apparatus in a predetermined sequence. A system controller 234 provided in connection with the host computer 232 corresponds to barcode print data supply means and print barcode verification means in the present invention. The operation panel 4 is used to issue a process start command to the system controller 234 and manually input label pasting specifications.

Hereinafter, the barcode printing processing procedure of the embodiment apparatus will be explained with reference to the flowchart shown in FIG.

First, the system controller 234 provides barcode printing data given from the host computer 232 to the barcode printer 6 (step S1). As shown in FIG. A barcode label is fed out from the loop 45, and a barcode based on the barcode print data is printed by the thermal print head 44 (step S2).
). The printed barcode label is sent to the next barcode reader, and the barcode is read (step S3). The read data is sent to the system controller 234, and it is verified whether the read data matches the corresponding barcode print data (step S4).

If the two match, it is assumed that printing has been performed normally, and the barcode label is fed out onto the peeling plate 32 (step S5), and the barcode label is moved to the barcode label positioning unit 8 as described above. After positioning, the barcode label is sucked and held by the upper part 10 of the pasting bar, transported to the barcode label pasting position, and the barcode label is pasted at a predetermined position on the board (step 36). Then, the process returns to step S1, and barcode printing data corresponding to the next board is given to the barcode printer 6, and the same process is repeated.

If the read data and the corresponding barcode print data do not match, it is determined that printing has not been performed normally, and the process proceeds to step S7, where the barcode label is peeled off in the same manner as described above. Pay out onto plate 32.

Then, the number of barcode printing attempts N is counted up by rl, and it is determined whether the value has reached a predetermined value N0. If NUN, proceed to step SIO. In this step 510, the barcode label with the printing error is delivered to the pasting head section 10 via the barcode label positioning section 8, and the X-Y axis drive mechanism 12.14 is driven to move the pasting head section 10 to a predetermined position. The barcode label is moved to the barcode label disposal position, and the barcode label with the printing error is discarded at that disposal position. and,
Returning to step S1, the same barcode printing data is given to the barcode printer 6 again to print the barcode, and it is determined in step S4 whether printing was performed normally.

Even if the same barcode is printed N0 times, if the read data does not match the corresponding barcode print data, it is assumed that some abnormality has occurred and the process proceeds to step Sll, where the device is stopped and a signal is sent. The light 22 is turned on to notify the operator of the abnormality.

In the above embodiment, the barcode label positioning section 8 for positioning the barcode label is provided separately from the pasting head section 10, but the pasting head 66 of the pasting head section 10 is provided with a positioning pin. 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.

Further, in the above-described embodiment, a barcode label with a printing error is pasted and carried to a disposal position by the upper part 10 of the barcode label, and the barcode label is discarded. When feeding out the barcode label from the barcode printer 6, the barcode label positioning section 8
Alternatively, the holding plate 50 of the barcode printer 6 may be configured to be retractable and the holding plate 50 may be moved in and out in the event of a printing abnormality. By making the bending angle of the separator S at the tip of the peeling plate 32 gentler, the barcode label with printing abnormality is prevented from peeling off from the separator S, and the barcode label is sent downward together with the separator S. It may be discarded.

<Effects of the Invention> As is clear from the above description, the following effects are achieved according to the present invention.

That is, since the barcode print data supply means supplies barcode print data to the barcode printer for each workpiece, even if the specifications of the workpiece change, the printed barcode is automatically changed accordingly. This eliminates the need for the operator to replace the barcode label reel every time the work specifications change, which is the case with conventional devices, and improves the operating rate of the device.

In addition, barcode printing errors are automatically detected based on whether the data read from the barcode label matches the corresponding barcode print data, and if a printing error occurs, the Since the code labels are automatically discarded, there is no need for the operator to remove and discard the barcode labels with printing errors each time, and in this respect as well, the operating rate of the apparatus can be further improved.
