Description

  The present invention relates to a temperature management device for managing the temperature of a soldering iron.

Assembling work of various electric products using electronic parts such as IC is usually performed by a flow work, and this work process includes a soldering work. When the soldering operation is performed manually, the operator tends to set and adjust the tip temperature to a higher level because the work efficiency is prioritized. Thus, when the tip temperature is set high, the electronic components are likely to be thermally destroyed or deteriorated, resulting in a decrease in product yield and a decrease in quality.
This tendency becomes more prominent as lead-free solder containing no lead spreads. That is, since lead-free solder has a higher melting point than conventional lead-containing solder, an operator who fears a decrease in work efficiency sets the tip temperature higher, and as a result, the electronic component is thermally destroyed. Things were happening.

  As such measures, temperature management devices as shown in Patent Documents 1 to 3 are known, in which an identification card is used to identify a manager, or temperature setting adjustment is performed only using a card or barcode. It is possible. However, giving a high-performance temperature management device having a card / barcode reader function as disclosed in Patent Documents 1 to 3 to all workers is a cost burden on the factory side or the company side that is the introduction of the device. Is large and cannot be said to be practical.

Japanese Utility Model Publication No. 1-80262 (Fig. 1-3) Japanese Utility Model Publication No. 1-30141 (Fig. 1-3) Japanese Utility Model Publication No. 1-84871 (Fig. 1-4)

  For this reason, in the present situation, a form in which the operator is required to measure the temperature of the tip at a frequency of several times (about 3 degrees) / day and the measurement result is recorded on a recording sheet is widely adopted. However, it is difficult to say that such temperature management is perfect in view of factors such as erroneous measurement temperature entry, entry mistakes, or erroneous entry of a temperature different from an artificial measurement result. For workers, handwriting is troublesome, and there is also a dissatisfaction that work efficiency decreases.

  In addition, the management of data by the administrator is complicated and troublesome. That is, it is necessary to carry out a check operation comparing handwritten data (measured temperature) and the allowable temperature range several times a day, which takes time and is troublesome. There is also a disadvantage that check mistakes are likely to occur. In particular, there are several types of solder handled in the factory, and check mistakes are likely to occur when the allowable temperature range of each solder is different.

  The present invention has been made to solve the above problems, and the temperature of the soldering iron that can appropriately manage the temperature of the soldering iron tip while reducing the labor of the operator and the manager. An object is to provide a management apparatus.

  As shown in FIGS. 1 and 4, the temperature management device 1 for a soldering iron according to the present invention includes a temperature measuring unit 19 that measures the temperature of the tip 7 of the soldering iron 6, and the temperature measuring unit 19. A control unit 31 that determines whether or not the measured temperature is within the allowable temperature range, a code reader 3 that reads the code 17 attached to each soldering iron 6, and notification means 26 that notifies the determination result.・ 27. Based on the identification information and allowable temperature information of each soldering iron 6 included in the code 17 read by the code reader 3, the control unit 31 determines whether the detected temperature is within the allowable temperature range. It is characterized in that it is judged whether or not the product is good, and the judgment result is notified to the notification means 26 and 27.

In the present invention, the “cord 17 attached to the soldering iron 6” means that the grip 17 or the cord of the soldering iron 6 is attached with the cord 17 or a control device for controlling the temperature of the soldering iron 6. 5 or the like in which the code 17 is attached to the casing. The code 17 is not limited to a two-dimensional code as shown in the embodiment, but includes a concept including an IC chip in which the code is stored. The code reader 3 reads a two-dimensional code or a code stored in an IC chip. When the code is stored in the IC chip, the IC chip is mounted on the base made of plastic or paper, and a sticker or a card is used. . The concept of the code 17 is the same in the following operator code 37 and solder type code 67.
Specific examples of the notification means 26 and 27 include a speaker that emits a buzzer sound, an LED for displaying a determination result of OK / NG, and the like.

  For the solder type in which the type of the solder 60 is recorded on the outer surface of the flange 62 of the solder reel 61 in which the solder 60 of the wire is wound around the hub or the outer surface of the reel base 64 that rotatably holds the solder reel 61. A form in which the code 67 is arranged can be taken.

  The external memory 22 includes a memory mounting portion 23 to which the external memory 22 is detachably mounted, and the control unit 31 associates at least the identification information of each soldering iron 6 included in the cord 17 with the determination result of the temperature determination to the outside. The form recorded in the memory 22 can be taken. Note that the phrase “at least” assumes that the type information of the solder 60 is recorded in association with the identification information of the soldering iron 6.

The code reader 3 can read a worker code 37 for identifying a worker who uses the soldering iron 6, and the control unit 31 is included in the worker code 37 read by the code reader 3. It is possible to record at least the identification information of the soldering iron 6 and the determination result of the temperature determination in the external memory 22 in association with the worker identification information for identifying the worker who is present.
The worker code 37 can be attached to the name tag 36 of each worker. It may be attached to a workbench performing soldering work.

  The temperature measuring unit 19 is configured to be separable from the apparatus main body 2 in which the control unit 31 and the memory mounting unit 23 are arranged, and the temperature measuring unit 19 is measured by mounting the temperature measuring unit 19 on the apparatus main body 2. The form in which the data of the detected temperature is read by the control unit 31 can be taken.

  In the present invention, a user such as an administrator or an operator causes the code reader 3 to read the code 17 attached to the soldering iron 6, and before and after this reading operation, the tip 7 of the soldering iron 6 is used. Is measured by the temperature measurement unit 19. The control unit 31 compares the allowable temperature obtained by the reading operation of the code 17 with the detected temperature measured by the temperature measuring unit 19, and if the detected temperature is within the allowable temperature range, the control unit 31 determines OK. If the detected temperature is outside the allowable temperature range, an NG determination is made and the determination result is notified by the notification means 26 and 27.

However, according to the temperature management device of the present invention, the operator and the manager can instantly grasp whether or not the detected temperature is within the allowable temperature range by using the notification means 26 and 27 such as sound and light. Therefore, the operator and the manager can know the temperature state of the tip 7 immediately without the trouble of checking the temperature within the allowable range or comparing the detected temperature with the soldering temperature associated with the temperature inspection. A reduction in work efficiency of the attaching work can be minimized.
In addition, since it is possible to eliminate the collation operation between the temperature within the allowable range and the detected temperature by the administrator, the administrator can use each soldering iron 6 only by confirming the determination result by the notification means 26 and 27. You can grasp and manage the situation. Therefore, it is possible to greatly reduce the labor of management work and reduce the burden on the administrator.
Above all, since the temperature of the tip 7 is determined based on the information on the allowable temperature included in the code 17, it is possible to completely eliminate the operation of checking the allowable temperature range. Therefore, even when the allowable temperature ranges of the plurality of soldering irons 6 are different, the temperature of the tip 7 can be accurately determined, and it is excellent in that there is no room for erroneous determination.

  The allowable temperature of the tip 7 of the soldering iron 6 is initially determined by the type of solder that the soldering iron 6 performs the soldering operation as one major factor. Accordingly, a solder identification code 67 on which information on the type of the solder 60 is recorded is disposed on the outer surface of the flange 62 of the solder reel 61 or the outer surface of the reel base 64 that rotatably holds the solder reel 61. If the quality determination is performed based on the type information read from the code 67, the quality determination can be performed more reliably, and a temperature management device with higher reliability can be obtained. Corresponding to the identification information of the soldering iron 6, the type information of the solder 60 can be managed, the labor of management work can be greatly reduced, and the burden on the manager can be reduced. The information stored in the cord 17 attached to the soldering iron 6 is compared with the information stored in the code 67 attached to the solder reel 61 etc., and the information is handled by the soldering iron 6 from both information. It is also possible to confirm whether or not the solder 60 is designated. That is, if the type information of the solder 60 is attached to the cord 17, the solder 60 used for the soldering operation by the soldering iron 6 is compared by comparing the type information with the type information of the code 67. It is possible to easily and surely confirm whether or not it is designated. Further, the result of the confirmation operation can be notified through the previous notification means 26 and 27.

The external memory 22 has a memory mounting portion 23 to which the external memory 22 is detachably mounted, and the control unit 31 associates the identification information of each soldering iron 6 included in the cord 17 with at least the temperature determination result as the external memory 22. It is possible to take the form of recording in According to this, it is possible to save the troublesome trouble of the operator measuring the temperature of the tip 7 with the thermometer and recording it on the recording paper, which can contribute to the improvement of the work efficiency of the soldering work. It is possible to completely eliminate errors in measuring temperature, mistakes in writing, human error, etc., and the temperature of the tip 7 can be properly managed.
If the data stored in the external memory 22 is moved to a personal computer or the like and aggregated using spreadsheet software or the like, the temperature status of the soldering iron 6 can be managed at a glance on the screen of the personal computer. . Therefore, it is possible to greatly reduce the administrative work burden on the administrator. Even in the case of a large-scale factory, the use status of the soldering iron 6 can be reliably managed by a small number of managers.

  If the identification information of the soldering iron 6 and the determination result of the quality determination, and in some cases, the solder type information, etc. are recorded in the external memory 22 in association with the worker identification information, management and guidance can be performed in units of workers. Become. Therefore, a more detailed management system can be established.

If the temperature measuring unit 19 is separable from the apparatus main body 2, for example, only the temperature measuring unit 19 is given to the worker, and when this comes to the inspection time, the temperature is measured by turning to each worker in order. After the measurement of all persons is completed, the temperature measurement unit 19 is collected, and this is mounted on the apparatus main body 2 so that the control unit 31 reads the data of the detected temperature and adopts a usage pattern in which the quality is determined. it can. According to this, the operator only has to operate the temperature measuring unit 19 specialized for the temperature measuring function, compared with the case where each operator operates the entire temperature management device 1 having many operation buttons. The operation burden on the operator is reduced. Since the temperature can be measured more quickly, the reduction in work efficiency associated with the inspection work can be reduced. Since one apparatus main body 2 can correspond to a plurality of temperature measuring units 19, if the number of workers increases, the number of temperature measuring units 19 may be increased, and the cost burden on the factory side or the company side is increased. Can be suppressed. The thermistor and the like of the temperature measuring unit 19 are easily consumed, but it is also excellent in that maintenance and inspection or replacement of consumable parts such as the thermistor can be facilitated by separating this from the apparatus main body 2.
However, in the case of the use form as described above, it is necessary to register each soldering iron 6 or an operator in the temperature measuring unit in advance, and the operator must have the soldering iron 6 prior to the inspection. The identification information or the operator name is displayed on the display screen of the temperature measurement unit, and after the soldering iron 6 and the operator are authenticated or confirmed, the actual temperature is measured.

The code 67 includes the type information of the solder 60 (product number of the solder 60, etc.) encoded. In some cases, in addition to the type information, allowable temperature information of the tip 7 of the solder 6 may be included.

  On the side surface of the apparatus main body 2 of the temperature management apparatus 1, a temperature measuring unit 19 for measuring the temperature of the tip 7, a connector 21 to which a connector 20 of the two-dimensional code reader 3 is detachably connected, and an SD memory card A memory connector (memory mounting portion) 23 to which the external memory 22 is detachably connected (mounted) is disposed. Here, the connector 20 of the two-dimensional code reader 3 and the connector 21 of the apparatus main body 2 are USB standard terminals. On the front surface of the apparatus main body 2 of the temperature management apparatus 1, an operation unit 25 including a power switch and the like, a display unit (notification unit) 26 for displaying the temperature of the tip 7 measured by the temperature measurement unit 19, and notification A buzzer (notification means) 27 is provided. The temperature measuring unit 19 has a thermocouple 29, and the tip 7 comes into contact with the thermocouple 29 (see FIG. 3), and its temperature is measured. As shown in FIG. 2, the apparatus main body 2 includes a control unit 31 that controls the entire apparatus, a ROM 32 that stores a startup program and the like, and a storage unit 35 that includes a RAM 33 that serves as a work area for the control unit 31. Is provided.

  The two-dimensional code reader 3 can read not only the two-dimensional code 17 for the soldering iron but also the two-dimensional code (code) 37 (FIG. 3) for the worker placed on the name tag 36 owned by the worker. it can. The worker two-dimensional code 37 includes worker identification information (name, etc.) coded to identify the worker.

  Next, the operation of the temperature management device 1 according to the present embodiment will be described. First, prior to measuring the temperature of the tip 7 of the soldering iron 6, for example, the manager operates the two-dimensional code reader 3, and the two-dimensional code 37 for the worker, the two-dimensional code 17 for the soldering iron, the solder The solder type two-dimensional code 67 attached to the reel 61 is read. Based on the read two-dimensional code 17, 37, 67, the control unit 31 of the temperature management device 1 performs soldering iron data (identification information of the soldering iron 6), allowable temperature range data (allowable temperature information), an operator The data and the type information of the solder 6 are stored in the RAM 33.

  Next, the manager brings the tip 7 of the soldering iron 6 into contact with the thermocouple 29 of the temperature measuring unit 19 and presses the button of the operation unit 25 in this state, thereby measuring the iron measured by the temperature measuring unit 19. The temperature data of the first 7 is read into the control unit 31. Then, the control unit 31 compares the measured temperature data of the tip 7 with the allowable temperature range data, and when it is determined that the temperature of the tip 7 is within the allowable temperature range, the display unit 26. The temperature of the tip 7 and “OK” are displayed (notified).

  On the other hand, when the control unit 31 determines that the temperature of the tip 7 is out of the allowable temperature range, the temperature of the tip 7 and “NG” are displayed (notified) on the display unit 26. At the same time, the buzzer 27 is sounded (notified). Thereafter, when the administrator presses the button on the operation unit 25, the temperature measurement unit 19 finishes measuring the temperature of the tip 7, and the display of “OK” or “NG” on the display unit 26 is deleted. When the buzzer 27 is sounding, the sound of the buzzer 27 is stopped. When the measurement of the temperature of the tip 7 is completed, the manager removes the tip 7 from the temperature measuring unit 19. In the case of “NG”, the manager adjusts the temperature of the tip 7 to an appropriate temperature with the temperature adjustment knob 15 of the soldering iron control device 5 or repairs the soldering iron 6.

  When the measurement of the temperature of the tip 7 is completed, the control unit 31 determines the measurement date / time data, the temperature data of the tip 7 measured by the temperature measurement unit 19, and the determination result of the temperature of the tip 7 (OK or NG). ) Data, operator identification information, and solder 60 type information are recorded in the external memory 22 in association with the soldering iron 6 identification information. When managing a plurality of soldering irons 6, a series of measurement operations such as reading of the two-dimensional codes 17, 37, and 67 and temperature measurement are repeated for each soldering iron 6. This measurement operation is performed about three times a day, for example.

  When the measurement operation for all the soldering irons 6 is completed, the administrator removes the external memory 22 (SD card) from the apparatus main body 2 and loads it into the memory reader of the personal computer. Data such as measurement date / time data, temperature data, worker identification information, identification information of solder 60 and soldering iron 6 and judgment results are transferred to a storage device (hard disk) of a personal computer, and then dedicated software, spreadsheet software, etc. And display this data as a list on the display of the personal computer. This list can be printed out as appropriate.

As described above, when the temperature management device 1 according to the present embodiment is used, the operator and the administrator can determine whether the detected temperature is within the allowable temperature range from the display on the display unit 26 or the buzzer 27. Can be grasped instantly by the notification sound. Therefore, the operator and the manager can quickly know the temperature state of the tip 7 without the trouble of checking the allowable temperature, comparing with the detected temperature, and the like. The reduction in work efficiency can be minimized.
In addition, since it is possible to eliminate the collation operation between the allowable temperature and the detected temperature by the manager, the manager can manage the temperature state of each soldering iron 6 only by confirming the determination result by the notification means 27. . Therefore, it is possible to greatly reduce the labor of management work and reduce the burden on the administrator. It is also excellent in that the type of solder 6 can be easily and reliably confirmed.
Above all, the temperature of the tip 7 is determined based on the information on the allowable temperature included in the two-dimensional code 17, so that the operation for checking the allowable temperature range and the like can be completely eliminated. Therefore, even when the allowable temperature range of the plurality of soldering irons 6 differs for each soldering iron 6, the temperature of the tip 7 can be accurately determined, and there is no room for occurrence of a determination error. .

In association with the identification information of each soldering iron 6 included in the two-dimensional code 17, measurement date / time data, temperature data, worker identification information, solder 6 type information and determination results are recorded in the external memory 22. The troublesome trouble of measuring the temperature of the soldering tip 7 with a thermometer and recording it on the recording paper can be saved, and the work efficiency of the soldering work can be improved. It is possible to completely eliminate errors in measuring temperature, mistakes in writing, human error, etc., and the temperature of the tip 7 can be managed accurately and accurately.
If the data stored in the external memory 22 is moved to a personal computer or the like and aggregated using spreadsheet software or the like, the temperature of the tip 7 can be managed on the screen of the personal computer. Therefore, the administrator can completely eliminate the trouble of determining and checking whether or not the temperature recorded on the recording sheet is within the allowable temperature range, and the management work burden on the administrator can be greatly reduced. It is easy to catch and analyze trends in units of workers or 6 units of soldering iron, and management and guidance can be performed in units of workers or 6 units of soldering iron. Therefore, a more detailed management system can be established.

Second Embodiment A second embodiment of the temperature management device 1 for a soldering iron according to the present invention will be described with reference to FIGS. The temperature management device 1 according to the second embodiment is greatly different from the first embodiment in that the temperature measurement unit 19 is separable from the device main body 2.

  Specifically, as shown in FIGS. 4 and 5, an operation unit 39 including a power switch and a display unit 40 for displaying the measured temperature of the tip 7 are arranged on the front surface of the temperature measurement unit 19. Further, on the side surface of the temperature measurement unit 19, a thermocouple 29, a main body connection connector 41 for removably connecting (attaching) to the apparatus main body 2, and a printer 42 (FIG. 8) for removably connecting. The printer connector 43 is arranged. Inside the temperature measurement unit 19, a secondary battery 45 (FIG. 5) for power supply is disposed, and as shown in FIG. 6, a control unit 46 and a storage unit 50 including a ROM 48 and a RAM 49 are provided.

  As shown in FIG. 4, an operation unit 25, a display unit (informing unit) 26, and a buzzer (informing unit) 27 are disposed on the front surface of the apparatus main body 2, and an external memory 22 is disposed on the side surface of the apparatus main body 2. A memory connector (memory mounting portion) 23 that is detachably connected (attached) and a main body connection connector 41 of the temperature measurement portion 19 are detachably connected (attached) to a measuring portion connection connector 51 (FIG. 9). ) Is arranged. As shown in FIG. 7, the apparatus main body 2 includes a control unit 31 and a storage unit 35 including a ROM 32 and a RAM 33. In the present embodiment, a USB memory is employed as the external memory 22 and a USB standard terminal is employed as the memory connector 23.

Next, the operation of the temperature management device 1 according to the second embodiment will be described. Here, first, the temperature measurement unit 19 alone is used to measure the temperature of the plurality of soldering irons 6, and then the usage mode in which the temperature measurement unit 19 is connected to the apparatus main body 2 will be described.
In such a usage pattern, prior to the temperature measurement by the temperature measurement unit 19, the soldering iron 6 and the operator are registered in the temperature measurement unit 19 and the apparatus main body 2. Specifically, the administrator operates the two-dimensional code reader 3 of the apparatus main body 2 to perform a reading operation on the two-dimensional code 37 for the worker, the two-dimensional code 17 for the soldering iron 6, and the solder identification code 67. The identification information of the soldering iron 6, the worker identification information, the allowable temperature range information, and the type information of the solder 6 are stored in the RAM 33 of the storage unit 35 of the apparatus body 2 and the RAM 49 of the storage unit 50 of the temperature measurement unit 19.

  When the inspection time comes, the temperature measurement unit 19 is given to the operator to measure the temperature. The operator operates the operation unit 39 to display the worker identification information or the identification information of the soldering iron 6 on the display unit 40, and further operates the operation unit 39 to perform the authentication / confirmation operation. Then, the tip 7 of the soldering iron 6 is brought into contact with the thermocouple 29 of the temperature measuring unit 19 to measure the temperature. The detected temperature and the detected time are stored in the RAM 49, and the detected temperature and the allowable temperature range are displayed on the display unit 40. Based on this detected temperature, the operator performs temperature control. When there are a plurality of workers, the temperature measurement unit 19 is sequentially advanced, and each worker performs an authentication / confirmation operation and a temperature measurement operation, and stores the detected temperature in the RAM 49. For example, a plurality of groups of a plurality of workers may be provided for each line in the factory or for each manufacturing process, and one temperature measuring unit 19 may be given to each group. The temperature measurement unit 19 is rotated to perform the authentication / confirmation operation and the temperature measurement operation.

  When the temperature measurement for all workers to be measured is completed, the administrator collects the temperature measurement unit 19 and attaches the temperature measurement unit 19 to the connector 51 of the apparatus main body 2 as shown in FIG. As a result, the detected temperature and detection time data stored in the RAM 49 of the temperature measuring unit 19 are read by the control unit 31 of the apparatus main body 2 together with the worker identification information and the identification information of the soldering iron 6, and the RAM 33. Stored in. The control unit 31 displays worker identification information, identification information of the soldering iron 6, allowable temperature information, measurement time, and the like on the display unit 26. The administrator checks the data displayed on the display unit 26, and presses the button on the operation unit 25 if the data is correct. In response to this, the control unit 31 of the apparatus main body 2 compares the temperature data of the tip 7 with the allowable temperature information, and determines that the temperature of the tip 7 is within the allowable temperature range. “OK” is displayed (notified) on the display unit 26 of the apparatus main body 2. On the other hand, when the control unit 31 of the apparatus main body 2 determines that the temperature of the tip 7 is out of the allowable temperature range, the display unit 26 displays (notifies) “NG” and the buzzer 27. Sound (notify). This determination operation may be performed for each soldering iron 6 or may be performed for a plurality of soldering irons 6 collectively.

  The control unit 31 of the apparatus main body 2 records the measurement date and time, the detected temperature, the determination result, and the worker identification information in the external memory 22 in association with the identification information of the soldering iron 6. The administrator removes the external memory 22 from the apparatus main body 2 and loads it into the USB terminal of the personal computer. After moving data such as measurement date and time data, temperature data, worker identification information, identification information of soldering iron 6, type information of solder 60 and determination result to a storage device (hard disk) of a personal computer, dedicated software or Spread the spreadsheet software and display this data as a list on the display of the personal computer. This list can be printed out as appropriate.

  If the temperature measuring unit 19 is separable from the apparatus main body 2 as in the second embodiment, only the temperature measuring unit 19 is given to the operator as described above, and each operation is performed in turn at the inspection time. The temperature measurement unit 19 is collected after the measurement by all the workers is completed, and the temperature measurement unit 19 is collected and attached to the apparatus main body 2 so that the control unit 31 can read the data of the detected temperature, and pass / fail judgment is made. It is possible to adopt a usage pattern such as According to this, the operator only has to operate the temperature measuring unit 19 specialized for the temperature measuring function, compared with the case where each operator operates the entire temperature management device 1 having many operation buttons. The operation burden on the operator is reduced. Since the temperature can be measured more quickly, the reduction in work efficiency associated with the inspection work can be reduced. Since one apparatus main body 2 can correspond to a plurality of temperature measuring units 19, if the number of workers increases, the number of temperature measuring units 19 may be increased, and the cost burden on the factory side or the company side is increased. Can be suppressed. Although the thermistor of the temperature measuring unit 19 is easily consumed, it is also excellent in that maintenance and inspection or replacement of consumable parts such as the thermistor can be facilitated by separating this from the apparatus body 2.

In addition to the use form as described above, the administrator may go around the work table and measure the temperature. In this case, the administrator operates the two-dimensional barcode reader 3 of the apparatus main body 2 to read the worker identification information, the identification information of the soldering iron 6, the type information of the solder 60 and the allowable temperature information, Before and after the reading operation, the temperature of the soldering iron 6 is measured using the temperature measuring unit 19. The detected temperature and the measurement time are stored in the RAM 49 of the temperature measurement unit 19.
