The above is an example of unusable information, and the information notified by the audio output unit as unusable information can be appropriately changed according to the configuration of the tube joining device.

As described above, the information in the range of normal use and the information in the unusable state are more important than the information in the range of normal use. In order to clarify the difference in importance, different guide sounds (melody) may be added before each information.

<Power supply unit>
The power supply unit 80 has a function of supplying electric power to each part of the tube joining device 1. As shown in FIGS. 1 and 3, the power supply unit 80 includes a battery 81 capable of supplying electric power to each unit and a charger 82 for charging the battery 81.

<Control unit>
The control unit 90 can be configured by a microcomputer or the like. The control unit 90 includes a CPU and a storage unit that stores a control program for the entire device executed by the CPU and various data. The storage unit can be configured by a ROM, RAM, or the like.

As shown in FIG. 12, the control unit 90 includes a power supply unit 80, an operation unit 60, a notification unit 70, a tube detection unit 24, an open / close detection unit 26, an interlock 30, a temperature sensor 11e, a wafer detection unit 42, and a feed unit. It is electrically connected to 50 mag. The control unit 90 controls each unit in an integrated manner.

The CPU of the control unit 90 has a function as a determination unit for determining the volume of the voice output unit 73 and a function as an operation control unit for controlling the operation of the voice output unit 73 based on the determination result of the determination unit. Each function will be described in detail below.

When the volume of the voice output unit 73 set by the volume setting unit 63 is equal to or higher than the reference volume, the determination unit sets the volume of the voice output unit 73 for notifying all the information by the volume setting unit 63. Judge to make the volume. When the volume of the voice output unit 73 set by the volume setting unit 63 is lower than the reference volume, the determination unit of the voice output unit 73 makes a notification according to the importance of the information notified by the voice output unit 73. It is determined whether the volume is set to the volume set by 63 in the volume setting unit or the reference volume.

The reference volume is not particularly limited as long as the user M can hear it, but for example, the volume of the voice output unit 73 can be set to a value equal to or less than the median within a range in which the volume of the voice output unit 73 can be set by the volume setting unit 63. For example, in the present embodiment, the range in which the volume of the voice output unit 73 can be set by the volume setting unit 63 is a range from silence to a fourth volume. Therefore, the median value in the range in which the volume of the voice output unit 73 can be set by the volume setting unit 63 means the second volume. In this case, for example, the reference volume can be set to the first volume or the second volume as a value equal to or less than the median value.

For example, an example in which the reference volume is the second volume will be described. When the volume of the voice output unit 73 is set to the reference volume (second volume) or higher by the volume setting unit 63, the determination unit sets the volume of the voice output unit 73 at the time of notifying all the information. It is determined that the volume is set by 63 in the unit. Then, when the volume of the voice output unit 73 is set to silence (or the first volume) by the volume setting unit 63, the determination unit notifies the voice output unit 73 according to the importance of the information to be notified. It is determined whether the volume of the voice output unit 73 is silenced (or the first volume) or the reference volume (second volume).

In the present embodiment, when the volume of the voice output unit set by the volume setting unit 63 is lower than the reference volume, the determination unit of the voice output unit 73 when notifying the information within the range of normal use. It is determined that the volume is set to the volume set by the volume setting unit 63, and the volume of the voice output unit 73 at the time of notification is used as the reference volume for information outside the normal use range and unusable information. Note that the reference volume may differ between information outside the range of normal use and information that cannot be used. For example, depending on the importance of information, the reference volume may be set to a relatively low first volume for information outside the normal use range, and the reference volume may be set to a relatively high second volume for unusable information.

The operation control unit adjusts the volume of the voice output unit 73 according to the determination result of the determination unit, controls the operation of the voice synthesis unit, and causes the voice output unit 73 to output a predetermined voice.

<Usage example>
Next, a usage example of the tube joining device 1 will be described. First, as shown in FIG. 1, the user M inserts the wafer cassette WC containing the wafer WF into the cassette insertion hole 11c of the tube joining device 1 when using the tube joining device 1. Next, the user M presses the button of the operation unit 60 to turn on the power of the tube joining device 1.

Next, as shown in FIG. 15, the control unit 90 controls the operation of the voice output unit 73, and the voice output unit 73 opens the lid 22 to the user M and holds the tubes T1 and T2 into the holding unit 23. It is set and notified to close the lid 22 (ST1). Since this information is within the range of normal use, the determination unit determines that the voice output unit 73 notifies at a volume set by the volume setting unit 63.

The user M sets the tubes T1 and T2 in the holding portion 23 as shown in FIGS. 5 and 16. Next, the user M performs an operation of closing the lid portion 22 (an operation of bringing the lid portion 22 relatively close to the housing 10). Since the lid portion 22 is closed, as shown in FIG. 2, the outer peripheral portion of the fusing portion of the tubes T1 and T2 is covered with the cover 223 and is isolated from the outside. This makes it possible to carry out the fusing-joining operation in an aseptic state.

The control unit 90 confirms whether the tubes T1 and T2 are set in the holding unit 23 by the tube detecting unit 24 and whether the lid portion 22 is closed by the open / close detecting unit 26 (ST2). When the set of the tubes T1 and T2 to the holding portion 23 and the closed state of the lid portion 22 cannot be detected (ST2: NO), the control unit 90 closes the set of the tubes T1 and T2 and the lid portion 22 to the audio output unit 73. (ST3). Since this information is outside the range of normal use, the judgment unit sets the volume of the audio output unit 73 to be the reference volume when the volume set by the volume setting unit 63 is smaller than the reference volume. to decide. When the volume set by the volume setting unit 63 is equal to or higher than the reference volume, the determination unit determines that the volume of the voice output unit 73 is the volume set by the volume setting unit 63.

When the tubes T1 and T2 are set in the holding portion 23 and the closed state of the lid portion 22 is detected (ST2: YES), the control unit 90 confirms whether the wafer WF is housed in the wafer cassette WC by the wafer detecting unit 42. (ST4). When the wafer WF is not stored in the wafer cassette WC (ST4: NO), the control unit 90 notifies the audio output unit 73 to store the wafer WF in the wafer cassette WC (ST5). Since this information is outside the range of normal use, the judgment unit sets the volume of the audio output unit 73 to be the reference volume when the volume set by the volume setting unit 63 is smaller than the reference volume. to decide. When the volume set by the volume setting unit 63 is equal to or higher than the reference volume, the determination unit determines that the volume of the voice output unit 73 is the volume set by the volume setting unit 63.

When the wafer WF is housed in the wafer cassette WC (ST4: YES), the control unit 90 causes the feed unit 50 to take out the wafer WF from the wafer cassette WC, and the fusing preparation position (the wafer WF in FIG. 18 is indicated by a broken line). It is sent out to the position where it is (ST6). Next, the control unit 90 confirms whether the wafer WF can be used for fusing (ST7). If the wafer WF is not suitable for fusing (ST7: NO), the control unit 90 notifies the audio output unit 73 that the wafer WF is not suitable for fusing or that the wafer WF is sent out again. Let (ST8). Since this information is outside the range of normal use, the judgment unit sets the volume of the audio output unit 73 to be the reference volume when the volume set by the volume setting unit 63 is smaller than the reference volume. to decide. When the volume set by the volume setting unit 63 is equal to or higher than the reference volume, the determination unit determines that the volume of the voice output unit 73 is the volume set by the volume setting unit 63. Then, the control unit 90 causes the feed unit 50 to take out the wafer WF from the wafer cassette WC again and send it to the fusing preparation position (ST6). At this time, the wafer WF that is not suitable for fusing is pushed out from the fusing preparation position by the next wafer WF.

When the wafer WF delivered to the fusing preparation position can be used (ST7: YES), the control unit 90 controls the operation of the audio output unit 73 and notifies that the tubes T1 and T2 are joined (ST9). Since this information is within the range of normal use, the determination unit determines that the voice output unit 73 notifies at a volume set by the volume setting unit 63.

Next, the control unit 90 operates the interlock 30 to lock the lid portion 22 in the closed state.

Next, the control unit 90 controls the operation of the heater to heat the wafer WF at the fusing preparation position (ST10). Then, the wafer WF heated by the feed unit 50 is moved to a fusing position (the position where the wafer WF in FIG. 18 is shown by a solid line), and fusing is performed as shown in FIG. 18 (ST11).

Next, the control unit 90 controls the operation of the rotation drive unit, and causes the tube pressing unit 25 to exchange the positions of the replacement side Y1 of the tube T1 and the replacement side Y1 of the tube T2 as shown in FIG. 19 (ST12). .. After that, the control unit 90 controls the operation of the straight drive unit, and as shown in FIG. 20, presses the ends of the tube T1 and the tube T2 replaced by the tube pressing unit 25 in the left-right direction Y to pressurize and join. (ST13).

Next, the control unit 90 unlocks the interlock 30 and controls the operation of the voice output unit 73 to notify that the joining is completed and to open the lid 22 and remove the tubes T1 and T2. (ST14). Since this information is within the range of normal use, the determination unit determines that the voice output unit 73 notifies at a volume set by the volume setting unit 63. Next, the user M performs an operation of opening the lid portion 22, and removes the tubes T1 and T2 from the tube joining device 1 as shown in FIG.

If the tube joining device 1 becomes unusable between steps ST1 to ST14 due to, for example, the interlock not operating or the rotation drive unit being stopped halfway, the control unit 90 transfers the audio output unit 73. Controls the operation of the tube joining device 1 to notify that the tube joining device 1 is in an unusable state and needs to be inspected. Since this information is unusable information, the determination unit determines that the volume of the voice output unit 73 becomes the reference volume when the volume set by the volume setting unit 63 is smaller than the reference volume. When the volume set by the volume setting unit 63 is equal to or higher than the reference volume, the determination unit determines that the volume of the voice output unit 73 is the volume set by the volume setting unit 63.

As described above, in the tube joining device 1, after the end portion of the tube T1 and the end portion of the tube T2 are fused by the heated plate-shaped wafer WF, the fused end portion of the tube T1 and the fused end of the tube T2 are fused. It is a tube joining device that joins by exchanging parts. The tube joining device 1 includes an audio output unit 73, a volume setting unit 63, a determination unit, and an operation control unit. The voice output unit 73 voicely notifies the information to be used for the tube joining device 1. The volume setting unit 63 can set the volume of the voice output unit 73 by the operation of the user. When the volume of the voice output unit 73 set by the volume setting unit 63 is lower than the reference volume, the determination unit of the voice output unit 73 makes a notification according to the importance of the information notified by the voice output unit 73. It is determined whether the volume is set to the volume set by the volume setting unit 63 or the reference volume. The operation control unit controls the operation of the voice output unit 73 based on the determination result of the determination unit.
