The substrate conveyors 32 and 34 supported by the substrate 31, the substrate holding devices 42 and 44, the component supply device 48, the head moving device 58, and the like. It should be noted that the electrical control device of the component mounting machine 10 is installed in the support base 30, and therefore it is appropriate to consider the part of the support base 30 that houses the electrical control device as the mounting machine body side.
The holding and releasing of the components by the suction nozzle 102 are controlled by a negative pressure supply device and a positive pressure supply device (not shown) provided on the mounting machine body side, and a combined pressure switching provided on the component mounting head 56. This is performed under the control of the unit 106 (see FIG. 8). The compound pressure switching unit 106 controls holding and releasing of parts by selectively supplying negative pressure and positive pressure to the suction nozzle 102 and opening the suction nozzle 102 to the atmosphere.

  The component mounter 10 can attach the diagnostic head 120 shown in FIG. 9 to the adapter 60 in place of the component mounting head 56. The diagnostic head 120 includes a head main body 122 that can be attached to and detached from the adapter 60 in the same manner as the head main body 104 of the mounting head 56a shown in FIG. The head main body 122 includes a compound pressure sensor unit 124 that can detect both positive pressure and negative pressure, and a positive pressure supply passage, a negative pressure supply passage, and an atmospheric pressure that are not illustrated for the compound pressure sensor unit 124. A compound pressure switching unit 126 that can selectively communicate with the passage is attached. The head main body 122 is further provided with an acceleration sensor unit 128 capable of detecting acceleration in the X-, Y-, and Z-axis directions and a printed circuit board 130. As the acceleration sensor unit 128, for example, a MEMS (Micro Electro Mechanical System) type acceleration sensor unit such as CXL10GP3 manufactured by Crossbow Co., Ltd. can be used, and the printed circuit board 130 has a continuous connection as shown in FIG. An electronic circuit 138 constituting the diagnosis unit 140 is formed in cooperation with the pressure sensor unit 124, the compound pressure switching unit 126, and the acceleration sensor unit 128. The electronic circuit 138 outputs a voltage / current sensor unit 142 that detects the voltage and current of the power supply to the diagnostic head 120, and outputs the voltage / current sensor unit 142, the combined pressure sensor unit 124, and the acceleration sensor unit 128. A / D converters 144, 146, and 148 that perform analog / digital conversion, a communication unit 150 that communicates with the main body side control unit 114, and a computer 152 are included.

  For example, communication between the communication unit 118 of the main body side control unit 114 and the communication unit 116 of the head side control unit 112 is communicated to an information request from the communication unit 118 such as “please specify an eigenvalue such as head mounting position error”. A first communication system that performs serial communication with relatively complicated contents such as a response from the unit 116, and a second communication system that transmits and receives signals with a strong demand for immediacy (for example, signals that change only to 0 and 1). , And the communication unit 150 of the diagnostic head 120 can perform communication similar to that of the communication unit 116. The computer 152 includes a CPU 154, a RAM 156, and a ROM 158. By fulfilling the functions shown in the functional block diagram of FIG. 11, abnormalities in the positive and negative pressures supplied to the diagnostic head 120, the voltage / current of the power supply A diagnosis unit 140 is configured to perform abnormality diagnosis such as abnormality, communication abnormality, and head moving device 58 abnormality.

When executing abnormality diagnosis, it is desirable to first confirm that there is no abnormality in communication. Even when an abnormality other than communication is found, information to that effect needs to be transmitted to the communication unit 118 of the main body side control unit 114 and displayed on the display device 16. This is because the display may not be performed properly.
In the present embodiment, first, a diagnosis is made as to whether there is an abnormality in the second communication system, and if there is no abnormality, a diagnosis is made as to whether there is an abnormality in the first communication system. The first communication system and the second communication system can each have a dedicated communication line, or can share the same communication line. Further, the communication units 118 and 150 may be unidirectional output or bidirectional output regarding the first communication system and the second communication system.

  The abnormality diagnosis of the second communication system is performed by loopback. The communication unit 150 of the diagnostic head 120 transmits, for example, one pulse signal to the communication unit 118 of the main body side control unit 114, and the second communication is performed depending on whether the one pulse signal is sent back from the communication unit 118 to the communication unit 150. A determination is made as to whether the system is normal or abnormal. The transmission of the 1-pulse signal in the communication unit 150, the return of the 1-pulse signal in the communication unit 118, and the presence / absence of the return of the signal in the communication unit 150 may be performed by a hardware circuit, It is also possible to be performed automatically. In any case, the result of the determination that it is normal, that is, the normal diagnosis result is transmitted to the communication unit 118 by the second communication system, and based on this, the display device 16 displays that the second communication system is normal. Done. On the other hand, when the second communication system is not normal, the normal diagnosis result is not transmitted to the communication unit 118 by the second communication system, so that the display device 16 displays that the second communication system is abnormal. . The display of the diagnosis result of the communication system of the display device 16 is set as “abnormal” in the initial setting, and when the normal diagnosis result is transmitted to the communication unit 118 by the second communication system, “normal. It is changed to the display of “Yes”.

  The abnormality diagnosis of the first communication system is performed by executing at least one of the erroneous transmission inspection methods such as parity check, checksum, CRC check (Cyclic Redundancy Check) and the like normally used for the erroneous transmission inspection of serial communication. For example, the communication unit 150 of the diagnostic head 120 serially transmits the value of “diagnostic head mounting position error” stored in the computer 152 in advance to the communication unit 118 and received by the communication unit 118. This value is sent back to the communication unit 150 as it is by serial communication, and the computer 152 executes the above-described erroneous transmission inspection method, thereby performing abnormality diagnosis of the first communication system. Instead of causing the computer 152 to execute the erroneous transmission inspection method, it is also possible to diagnose an abnormality using a commercially available LSI (Large Scale Integration). Regarding the transmission of the abnormality diagnosis result to the communication unit 118 by the first communication system and the display of the diagnosis result on the display device 16, the above description for the second communication system is applied as it is.

  Next, the positive and negative pressure abnormality diagnosis will be described. The switching unit control unit 170 of the diagnosis unit 140 constituted by the computer 152 controls the compound pressure switching unit 126 with a preset time chart via the drive circuit 172 (see FIG. 10), and the compound pressure sensor unit. 124 is communicated with the negative pressure supply passage and the positive pressure supply passage in order from the state of communication with the atmospheric pressure passage, and then returned to the state of communication with the atmospheric pressure passage. The pressure value converted by the D converter 146 is stored in the data storage unit 174. An example is shown in FIG. This pressure value is compared with each threshold value stored in the pressure database 176 in advance in the comparison / determination unit 178, and the presence / absence determination of the abnormality and the estimation of the cause of the abnormality are performed. For example, the pressure database 176 includes a negative pressure threshold value, an atmospheric pressure threshold value, a rise time that is a time required to reach the negative pressure threshold value from the atmospheric pressure, and a maximum negative pressure value until the atmospheric pressure threshold value is reached. Threshold values such as the fall time, the total time that is the time from the start of rising until reaching the atmospheric pressure threshold value, and the maximum negative pressure value are stored, and these threshold values are converted by the A / D converter 146. Based on the measured pressure value, the presence or absence of abnormality is determined, and if there is an abnormality, the cause is estimated. For example, in the example shown in FIG. 12, since the leak occurs due to deterioration of the seal member, the rise time is abnormally long, while the fall time is abnormally short, but the maximum negative pressure value is negative. The pressure threshold value is exceeded, and information indicating that the negative pressure supply device is normal but a seal member deterioration abnormality has occurred is transmitted to the main body side control unit 114 via the communication unit 150, and the display device 16 is displayed.

  The abnormality of the head moving device 58 is diagnosed as follows with respect to the presence or absence of aging of the guide of the head moving device 58 and the ball screw. After notification that the abnormality detection of the head moving device 58 should be started is performed from the main body side control unit 114 to the diagnostic head 120 via the communication units 118 and 150, the head moving device is controlled by the main body side control unit 114. 58 is operated in a pattern of either random excitation or sine excitation, and three analog outputs in the X, Y, and Z3 axis directions of the acceleration sensor unit 128 at that time are digitally converted by the A / D converter 148. Things are stored in the data storage unit 186. The frequency analysis unit 188 performs frequency analysis by FFT (Fast Fourier Transform) based on the stored digital output value, and the obtained result is compared with the data stored in the abnormal frequency database 190 in advance. In the determination unit 192, the presence / absence determination of the abnormality and the cause estimation when there is an abnormality are performed. FIG. 13 shows an example of the result of frequency analysis in the Y-axis direction that is the front-rear direction, in which both the aging deterioration of the guide and the aging deterioration of the ball screw have occurred. In FIG. 13, the solid line indicates the normal time, the broken line indicates the abnormal time, and the amplitude in the frequency region represented by the diagonal line rising to the right exceeds the threshold amplitude value represented by the alternate long and short dash line. It is determined that aging has occurred, and since the amplitude value in the frequency region represented by the slanting line to the right exceeds the threshold amplitude value represented by the two-dot chain line, aging of the ball screw has occurred. It is determined.

The abnormality of the power supply is detected as follows, for example. In the operating state of only the computer 152 and the operating state of both the computer 152 and the coupled switching unit 126, the voltage and current of the power line are detected by the voltage / current sensor unit 142 and the A / D converter 144, and data storage is performed. Stored in the unit 200. These stored voltage value and current value are compared with the standard values of voltage and current stored in advance in the voltage / current database 202, and if the absolute value of the difference exceeds the set value, the voltage or current An abnormality is detected.
The presence / absence of the abnormality of the head moving device 58, the abnormality of the power source voltage / current, and the estimation result of the cause of the abnormality are transmitted to the main body side control unit 114 via the communication unit 150 and displayed on the display device 16. The same as for abnormalities.

Although one embodiment of the claimable invention has been described in detail above, this is literally merely an example, and the claimable invention includes knowledge of those skilled in the art including the aspects described in the above [Aspect of the Invention] section. It can implement in the aspect which gave various changes based on this.
Specifically, in the embodiment described above, both the acquisition of information for diagnosing any abnormality and the diagnosis based on the acquired information are performed in the diagnosis unit 140 of the diagnosis head 120 in the embodiment described above. However, part or all of the diagnosis may be performed in the main body side control unit 114. In this case, detection values such as pressure, voltage, current, and acceleration are sent to the main body control unit 114 via the communication units 150 and 118.
The compound pressure switching unit 106 and its drive circuit are provided in the component mounting head 56, and the compound pressure switching unit 126 and its drive circuit 172 are also provided in the diagnostic head 120 correspondingly. This is because it is desirable to provide the component pressure switching unit 106 in the component mounting head 56 in order to reduce the supply delay of the negative pressure and the positive pressure to the suction nozzle 102 as much as possible. The driving circuit 126 may be provided in the main body side control unit 114 and shared. This is because there is no substantial delay problem.

Further, regarding communication abnormality, at least one of the communication unit 150 and the computer 152 of the diagnostic head 120 has a function of receiving a signal or information transmitted from the communication unit 118 and sending it back to the communication unit 118. It is also possible to make a diagnosis of the presence or absence of communication abnormality in the main body side control unit 114 based on the signal or information sent back. In this case, the “signal sent from the communication unit 118 or The function of receiving information and sending it back to the communication unit 118 can be considered as an information acquisition unit that acquires information for communication abnormality diagnosis.
Regarding communication, it is also possible to perform both acquisition and diagnosis of information for abnormality diagnosis in the main body side control unit 114. In addition to communication, all the information for diagnosing any abnormality can be sent to the overall control device, and the diagnosis can be performed there.

Moreover, in the said Example, although the movable member itself of the head moving apparatus 58 was made into the adapter 60 (it can also be considered that the adapter was comprised integrally with the movable member), as shown in FIG. It is also possible to separate the movable member 212 and the adapter 214 and attach the adapter 214 to the movable member 212 by a releasable fastening means such as a bolt 216.
Furthermore, by making the adapters larger than the mounting heads, etc., it is possible to selectively hold a plurality of types of mounting heads while holding the diagnostic units in the adapters. It is also possible to do.
