The terminal 50 blinks one LED of the status display lamp 15 corresponding to the fastening #m, and starts the instruction of the first guide 12 corresponding to the fastening #m (step S3). The terminal 50 determines whether or not the torque driver 30 has passed the first guide 12 of the indicated fastening #m (step S4). When the terminal 50 determines that the torque driver 30 has not passed the first guide 12 of the instructed fastening #m but has passed the other first guide 12 or the second guide 13 (step S4: No). ), A warning such as an output of a warning sound or blinking all the LEDs of the status display lamp 15 is executed for a predetermined time (step S5). After the warning, the terminal 50 returns the state of the status display lamp 15 to the state being instructed, and returns to the process of step S4.

When the terminal 50 determines that the torque driver 30 has passed the first guide 12 of the instructed fastening # m (step S4: Yes), the terminal 50 determines whether or not the screw is tightened with a predetermined torque (step). S6). When the terminal 50 determines that the screw is not tightened with a predetermined torque (step S6: No), the terminal 50 repeats the determination in step S6 and waits for the operator to complete the screw tightening work.

When the terminal 50 determines that the screw is tightened with a predetermined torque (step S6: Yes), the terminal 50 changes the LED of the status display lamp 15 corresponding to the fastening #m from blinking to lighting (step S7). The terminal 50 acquires the torque value when the screw is finished tightened from the torque driver 30, and works by associating the acquired torque value with the fastening #m of the corresponding first guide 12 and the ID of the operator. A log is generated, and the generated work log is stored in the storage unit (step S8).

The terminal 50 determines whether or not the fastening #m is the same as the number of screw holes (step S9). When the terminal 50 determines that the fastening #m is not the same as the number of screw holes, that is, the fastening #m is less than the number of screw holes (step S9: No), the terminal 50 increments m (step S10) and steps. Return to S3.

When the terminal 50 determines that the number of fastening #m is the same as the number of screw holes (step S9: Yes), the terminal 50 determines whether or not the number of fastenings n is the same as a predetermined number of fastenings (step S11). .. When the terminal 50 determines that the number of fastenings n is not the same as the predetermined number of times, that is, the number of fastenings n is less than the predetermined number of times (step S11: No), the terminal 50 initializes to m = 1 and increments n (step S12). ), Return to step S3.

When the terminal 50 determines that the number of times of fastening n is the same as the predetermined number of times (step S11: Yes), the terminal 50 terminates the fastening management process assuming that the attachment of the upper electrode 60 is completed. After that, the cover 80 is set on the upper electrode 60 by the operator, and the guide jig 10 is set so as to cover the cover 80. Further, the conversion switch 16 is set on the second guide 13 side, which is the outer peripheral side.

It blinks all the LEDs of. In the example of FIG. 9, if the screw inserted into the second guide 13 corresponding to the through hole 81 and the screw hole 62 is an appropriate screw 90, no warning information is output, and a screw having a standard different from that of the screw 90. For example, if the screw 91 is longer than the screw 90, warning information is output. In addition to the length, the screw standard includes diameter, pitch, head shape, tooth shape, and the like.

Further, a camera may be installed on the guide jig 10 or the torque driver 30, and it may be determined by image recognition whether or not the screws 90 and 91 inserted into the screw holes are appropriate screws. In this case, the guide jig 10 or the torque driver 30 captures an image of the screw inserted in the first guide 12 or the second guide 13 of the fastening portion, and transmits the captured image to the terminal 50. The guide jig 10 or the torque driver 30 may capture an image of the screw before being inserted into the first guide 12 or the second guide 13 of the fastening portion, and transmit the captured image to the terminal 50. good. The terminal 50 detects a screw by image recognition based on the received image, and determines whether or not the detected screw is an appropriate screw. The terminal 50 outputs warning information if the inserted screw is not an appropriate screw. An electronic tag reader or a camera may be provided on both the guide jig 10 and the torque driver 30.

In the following description, the processing of steps S1 to S12 of the fastening management processing is the same as that of the embodiment, and thus the description thereof will be omitted.

Following the process in step S3, the terminal 50 determines whether or not the inserted screw is an appropriate screw based on the received electronic tag information, for example, information on the screw standard (step S21). When the terminal 50 determines that the inserted screw is not an appropriate screw (step S21: No), the terminal 50 executes a warning such as outputting a warning sound and blinking all the LEDs of the status display lamp 15 for a predetermined time (step S22). ). After the warning, the terminal 50 returns the state of the status display lamp 15 to the state being instructed, and returns to the process of step S21.

When the terminal 50 determines that the inserted screw is an appropriate screw (step S21: Yes), the terminal 50 proceeds to the process of step S4. In the determination of step S21, the terminal 50 may detect the screw by image recognition based on the image obtained by capturing the screw, and may determine whether or not the detected screw is an appropriate screw. As described above, in the modified example 1, a warning is given when the screw inserted into the first guide 12 or the second guide 13 of the fastening portion is not appropriate, so that it is possible to suppress a work error such as a screw mistake. ..
