(motion)
Next, the operation of the system configured as described above will be described.
(1) Operation of Soldering Iron 1 When an operator grips the soldering iron 1 and brings the iron 12 into contact with the land of the object 4, the pressure (load) of the iron 12 on the object 4 at this time is applied. It is detected by the pressure sensor 15, and the detected value is transmitted as pressure data from the communication unit 17 to the work support device 2. At the same time, the tilt angle of the iron 12 with respect to the object 4 is detected by the tilt sensor 16, and the detected value is transmitted from the communication unit 17 to the work support device 2 as tilt data. After that, the pressure and tilt angle detection operation and the pressure data and tilt data transmission operation are continuously performed until the trowel 12 is separated from the object 4.

(2) Determination of Soldering Pressure and Tilt Angle by Work Support Device 2 The work support device 2 executes a process for supporting the soldering work as follows. FIG. 2 is a flowchart showing the entire processing procedure and processing content.

(2-1) Acquisition of Pressure Data and Tilt Data The radio signal transmitted from the communication unit 17 of the soldering iron 1 is received by the communication unit 21, separated into pressure data and tilt data, decoded, and then decoded. They are input to the pressure data acquisition control unit 23 and the tilt data acquisition control unit 24, respectively.

When the pressure data acquisition control unit 23 determines in step S1 that the soldering operation has started based on the pressure detection value indicated by the pressure data output from the communication unit 21, the pressure from the communication unit 21 in step S2. The data is sequentially taken in, and the information indicating the change in the pressure value is output to the quality determination / estimation unit 25. In parallel with this, the tilt data acquisition control unit 24 sequentially captures the tilt data from the communication unit 21 and outputs information indicating the change in the tilt angle to the quality determination / estimation unit 25 in step S3.

(2-2) Appropriate determination of pressure and tilt angle The quality determination / estimation unit 25 represents information indicating changes in pressure and changes in tilt angle from the pressure data acquisition control unit 23 and the tilt data acquisition control unit 24, respectively. When the information is taken in, the soldering pressure and the inclination angle are determined as follows in step S4. FIG. 3 is a flowchart showing the processing procedure and the processing content.

That is, the quality determination / estimation unit 25 first compares the information indicating the change in pressure in step S40 with the preset threshold value indicating the appropriate range of pressure, and whether the pressure value is within the appropriate range or appropriate. Determine if it is out of range. Then, when it is determined that the pressure value is out of the appropriate range, it is determined in step S41 whether the pressure value is larger or smaller than the appropriate range, and the determination result is output to the determination / estimation result transmission control unit 27. ..

Then, when the determination / estimation result transmission control unit 27 receives the determination result that the pressure value is larger than the appropriate range, the determination / estimation result transmission control unit 27 generates a display message indicating that the pressure value is “excessively pressed” in step S42, and transmits this display message to the communication unit. It is transmitted from 21 to the presenting device 3. Further, when the determination / estimation result transmission control unit 27 receives the determination result that the pressure value is smaller than the appropriate range, the determination / estimation result transmission control unit 27 generates a display message indicating “insufficient pressing” in step S43, and transmits this display message to the communication unit. It is transmitted from 21 to the presenting device 3. The display message includes a text message and a voice message having the same content.

Then, in step S44, the determination / estimation result transmission control unit 27 uses the information representing the determination result of the large / small pressure in step S41 and the pressure value at that time as the pressure determination history information of the object 4. It is stored in the storage unit 26 in association with the identification information (identification ID of the product).

Further, the quality determination / estimation unit 25 compares the information indicating the change in the tilt angle with the preset threshold value indicating the proper range of the tilt angle in step S45, and determines whether the tilt angle is within the appropriate range. Determine if it is out of the proper range. Then, when it is determined that the tilt angle is out of the appropriate range, it is determined in step S46 whether the tilt angle is larger or smaller than the appropriate range, and the determination result is output to the determination / estimation result transmission control unit 27. ..

Then, when the determination / estimation result transmission control unit 27 receives the determination result that the inclination angle is larger than the appropriate range, the determination / estimation result transmission control unit 27 generates a display message indicating “too much inclination” in step S47, and sends this display message to the communication unit. It is transmitted from 21 to the presenting device 3. Further, when the determination / estimation result transmission control unit 27 receives the determination result that the tilt angle is smaller than the appropriate range, the determination / estimation result transmission control unit 27 generates a display message indicating “insufficient tilt” in step S48, and sends this display message to the communication unit. It is transmitted from 21 to the presenting device 3. In this case as well, the display message includes a text message and a voice message having the same content.

Then, in step S49, the determination / estimation result transmission control unit 27 targets the information representing the determination result of the large / small inclination angle in step S46 and the value of the inclination angle at that time as the determination history information of the inclination angle. It is stored in the storage unit 26 in association with the identification information (product identification ID) of the object 4.

(2-3) Presentation of Display Message On the other hand, in the presentation device 3, when the display message is transmitted from the work support device 2, the display message is received by the receiving unit 31, and is visually recognized by the display unit 33 and the speaker 34. Displayed objectively and audibly.

For example, when a display message indicating "over-pressing" is received, a character message indicating "over-pressing" is displayed on the display unit 33, and the voice message is loudly output from the speaker 34. When a display message indicating "insufficient pressing" is received, a character message indicating "insufficient pressing" is displayed on the display unit 33, and the voice message is loudly output from the speaker 34. Therefore, the operator can immediately adjust the pressing force of the soldering iron 1 during the soldering operation.

On the other hand, when a display message indicating "too tilted" is received, the character message indicating "too tilted" is displayed on the display unit 33, and the voice message is loudly output from the speaker 34. When a display message indicating "insufficient tilt" is received, a character message indicating "insufficient tilt" is displayed on the display unit 33, and the voice message is loudly output from the speaker 34. Therefore, the operator can immediately adjust the tilt angle of the soldering iron 1 during the soldering operation.

(3) Estimating the quality of soldering (3-1) Calculation of soldering work time When the operator separates the soldering iron 1 iron 12 from the object 4, the pressure data transmitted from the soldering iron 1 is used. The indicated pressure detection value becomes zero. In step S5, the pressure data acquisition control unit 23 of the work support device 2 determines that the soldering work has been completed based on the pressure detection value indicated by the pressure data output from the communication unit 21.

The quality determination / estimation unit 25 uses the soldering start timing previously detected in step S1 and the soldering end detection timing detected in step S5 to determine the individual soldering points of the object 4 having a plurality of soldering points. Calculate the working time for the soldered area. Then, the calculated information representing the soldering work time for each portion is stored in the storage unit 26 in association with the identification information of the object 4. When the soldering work for one object 4 is completed, for example, the pressure detection value becomes zero after the soldering work for one soldering point is completed, and it is detected that there is no next soldering point for a predetermined time. It can be determined by detecting the elapse of the time (the time set to the extent possible).

(3-2) Quality Estimate Processing When the soldering work for one object 4 is completed, the quality determination / estimation unit 25 estimates the quality of the soldering work that has just been completed in step S6 as follows.
That is, the information representing the soldering determination history for the object 4 is read from the storage unit 26. At the same time, information indicating the soldering work time is read out. Then, the quality of soldering to the object 4 is estimated based on the determination history information and the soldering work time information.

For example, when the pressure value is P, the tilt angle value is R, and the time required for the soldering work is T, the soldering quality Q is Q = f (P, R, T) = αP + βR + γT.
Represented by. Note that α, β, and γ are weighting coefficients for pressure, tilt angle, and time, respectively, and are determined in advance.

Then, the pressure value, the inclination angle, and the working time value read from the storage unit 26 are substituted into the above relational expression to obtain the soldering quality Q. The obtained quality Q is stored in the storage unit 26 in association with the identification information (product identification ID) of the object 4.

(3-3) Transmission of quality estimation result It is assumed that the manager of the production line transmits a transmission request of the quality estimation result from a control terminal device (not shown) at a fixed time or an arbitrary time within the day, for example. When the work support device 2 receives the transmission request by the communication unit 21, the work support device 2 stores information representing the quality estimation result corresponding to the product identification ID specified by the transmission request under the control of the quality determination / estimation unit 25. Read from 26, and transmit information representing the quality estimation result from the communication unit 21 to the requesting control terminal device.
Therefore, the manager can extract the corresponding product and check the quality individually based on the information representing the quality estimation result.

(Effect of the first embodiment)
As described in detail above, in the first embodiment, in the work support device 2, the pressure and tilt angle data of the iron 12 with respect to the object 4 detected by the pressure sensor 15 and the tilt sensor 16 during the soldering work are obtained. Obtained from soldering iron 1, the obtained pressure value and tilt angle are compared with the threshold value to determine whether or not it is within the appropriate range, and if it is determined to be outside the appropriate range, a message to that effect is sent. It is displayed on the presentation device 3 so as to be presented to the operator.

Therefore, in response to the above message, the operator can adjust the pressing force and tilt angle of the soldering iron during the soldering work, which enables even a less skilled worker to have an appropriate pressure and tilt. The corners make it possible to perform soldering work. In addition, this makes it possible to increase the yield of soldering and maintain the quality of the product.

Further, in the first embodiment, the determination result of the pressure and the tilt angle during the soldering work and the pressure value and the tilt angle at that time are stored in the storage unit 26, and after the soldering work for one object 4 is completed. , The quality of the product is estimated based on the stored pressure value and tilt angle and the soldering work time, and the estimation result is output. As a result, the manager can extract the corresponding product and check the quality individually based on the above quality estimation result. It is also possible to estimate the skill level of the worker based on the above quality estimation result.

One of them lights up by the display signal indicating that the pressure detection value is out of the proper range, and the other one lights up by the display signal indicating that the tilt angle detection value is out of the proper range.

With such a configuration, when the operator starts the soldering work on the object 4, the pressure (load) of the trowel 12 on the object 4 is detected by the pressure sensor 15, and the detected value is the determination unit. It is input to 61. At the same time, the tilt angle of the trowel 12 with respect to the object 4 is detected by the tilt sensor 16, and the detected value is input to the determination unit 61.

The determination unit 61 compares the pressure detection value input from the pressure sensor 15 with the threshold value indicating the appropriate pressure range, and determines whether the pressure detection value is within or outside the appropriate range.
