  First, an electronic component mounting apparatus will be described with reference to FIG. The electronic component mounting apparatus 1 is an apparatus for mounting electronic components on a substrate, and includes four mounting portions 3 inside a housing 2. A substrate transport rail 4 is provided at a substantially central portion of the electronic component mounting apparatus 1, and the substrate is carried into the housing 2 from one side wall 5 along the substrate transport rail 4 and the electronic component is mounted. It is carried out from the other side wall 6. Two mounting portions 3 are arranged side by side on both sides of the substrate transport rail 4. Four doors 7 that open and close corresponding to each mounting portion 3 are formed on the upper portion of the housing 2. The operator opens the door 7 and performs maintenance and inspection work such as repair and adjustment of the mechanical system inside the housing 2 and replacement of consumable parts.

Touch panels 8 and 9 are provided at symmetrical positions with respect to the substrate transport rail 4 at the top of the housing 2. Among these, the touch panel 8 is arranged on the front side 1a of the electronic component mounting apparatus 1, and the touch panel 9 is arranged on the rear side 1b. The front-side touch panel 8 is an operation input unit through which an operator inputs commands and information related to the operation of the two mounting units 3 on the front side 1a, and the operator performs a machine trouble that occurs in the electronic component mounting measure 1. This is an error countermeasure display unit that visually displays effective error countermeasure information to be displayed. The same applies to the rear side touch panel 9. Further, an indicator lamp 10 is arranged on the side wall 6 side of the upper part of the housing 2. The indicator lamp 10 lights up in green when all four mounting parts 3 are operating safely, for example, lights up in red when any one of the mounting parts 3 is defective, and the operator is far away. Even if it exists, the work status of the electronic component mounting apparatus 1 can be notified.

  Next, a mechanism system inside the housing 2 of the electronic component mounting apparatus 1 will be described with reference to FIG. Each mounting unit 3 includes a parts feeder 21, a mounting head 22, an XY robot mechanism 23, an electronic component recognition unit 24, and a nozzle stocker 25 as main equipment.

  The parts feeder 21 is an electronic component supply unit that supplies a plurality of stored electronic components to a pickup position by the mounting head 22 in a posture capable of being picked up. A plurality of parts feeders 21 are mounted on each mounting unit 3.

  The mounting head 22 is attached to the XY robot mechanism 23. The XY robot mechanism 23 is a transfer head moving unit that moves the mounting head 22, and horizontally moves the mounting head 22 above the parts feeder 21 and the substrate 26. The mounting head 22 lowers the nozzle 27 to contact the upper surface of the electronic component supplied by the parts feeder 21, and sucks the inside of the nozzle 27 to attract the electronic component to the nozzle 27. The electronic component sucked by the nozzle 27 is picked up when the nozzle 27 is raised, and is transported to above the substrate 26 by driving the XY robot mechanism 23. The mounting head 22 mounts the electronic component on the upper surface of the substrate 26 by lowering the nozzle 27 again.

  The electronic component recognition unit 24 and the nozzle stocker 25 are arranged on the movement path of the transfer head 22. The electronic component recognition unit 24 is an electronic component recognition unit that captures an image of an electronic component that moves vertically upward and recognizes the position and orientation with respect to the nozzle 27 by shape recognition. As a result of the shape recognition, when a deviation of the position and orientation of the electronic component from the normal one is confirmed, the position and orientation of the electronic component are corrected by adjusting the position of the mounting head 22 and the angle of the nozzle 27, and then the substrate 26. If the electronic component is found to be unable to be repaired such as chipping or cracking, the mounting head 22 is moved to the disposal location of the electronic component and the electronic component is discarded.

  The nozzle stocker 25 stores a plurality of nozzles 28 having different sizes and shapes. These nozzles 28 are compatible with the nozzles 27, and the mounting head 22 returns the nozzles 27 to the nozzle stocker 25 when the mounted nozzles 27 do not correspond to the types of electronic components, and instead replaces the electronic components. Nozzles 28 corresponding to the types are attached.

  Next, a control system of the electronic component mounting apparatus 1 will be described with reference to FIG. The equipment control unit 30 performs drive control of each equipment constituting the electronic component mounting apparatus 1 such as the parts feeder 21, the mounting head 22, the XY robot mechanism 23, the electronic component recognition unit 24, and the nozzle stocker 25 described above.

The equipment control unit 30 includes an error type specifying unit 30a. The error type specifying unit 30a causes a machine trouble based on the driving state of each equipment when a machine trouble occurs in the electronic component mounting apparatus 1. The error type is identified and transmitted to the error countermeasure display control unit 31 as error type information. Further, the equipment control unit 30 includes an equipment state specifying unit 30b. The equipment state specifying unit 30b determines which equipment state, that is, the electronic component mounting apparatus 1 is based on the driving state of each equipment of the electronic component mounting apparatus 1. Whether such work has been performed is specified, and is transmitted to the error countermeasure display control unit 31 as equipment state information. In this way, the facility control unit 30 functions as an error type identifying unit that identifies the type of error that caused the machine trouble and a facility state identifying unit that identifies the facility state of the electronic component mounting apparatus 1 when the machine trouble occurs. To do.

  The error countermeasure display control unit 31 performs processing for reading out information regarding error countermeasures from the error countermeasure database 32 and transmitting the information to the error countermeasure screen display unit 33. The error countermeasure database 32 stores an error countermeasure storage unit that associates error countermeasure information with a combination of a plurality of patterns of equipment states and a plurality of patterns of error types in association with errors assumed in the electronic component mounting apparatus 1. Function as.

  An error countermeasure table 34 is stored in the error countermeasure database 32. As shown in FIG. 4, the error countermeasure table 34 is in the form of a matrix table in which the equipment state is arranged in the vertical direction and the error types are arranged in the horizontal direction, and error countermeasure information is written in a column where these intersect. The error countermeasure information is associated with all types of errors that are expected to occur in the electronic component mounting apparatus 1 and all equipment states where the errors are expected to occur, and is most effective for the combination thereof. Text data is used so that the operator can confirm possible error countermeasures.

  For example, an overload error in which the nozzle 27 descends beyond the lower limit height during the suction operation is caused by using an electronic component that is thinner than the electronic component that should be handled or a position that is different from the suction position where the nozzle 2 is supposed to be. The cause of the error is thought to be the suction operation. Therefore, in the column 35 where “overload” and “suction operation” of the error countermeasure table 34 intersect, text data “confirm component thickness” and “confirm suction position” are written as error countermeasure information. . Thus, it is necessary to complete the error countermeasure table 34 by performing in advance an operation for writing error countermeasures that are considered to be most effective for all error types and equipment states as text data. Since the error countermeasure table 34 can add or rewrite data, it can be updated at any time, for example, by increasing / decreasing items of error types and equipment states, or rewriting error countermeasure information.

  In FIG. 3, the error countermeasure search unit 36 searches the error countermeasure database 32 based on the equipment state information and error information transmitted from the equipment control unit 30 to the error countermeasure display control unit 31, and the corresponding error from the error countermeasure table 34. Read countermeasure information. The read error countermeasure information is transmitted to the error countermeasure screen display unit 33.

  FIG. 5 is an example of an error information screen displayed on the touch panels 8 and 9. A plurality of information display frames 38 to 43 are set on the screen 37 of the touch panels 8 and 9. Of these, the operation state of the electronic component mounting apparatus 1 is displayed in real time in the uppermost information display frame 38, indicating that the electronic component mounting apparatus 1 is in an “error stop” state in which the operation is temporarily stopped due to the occurrence of an error. ing. The information display frame 39 one level below displays information for notifying the operator that an error has occurred in the electronic component mounting apparatus 1. Further, detailed information regarding an error that has occurred in the electronic component mounting apparatus 1 is displayed from the information display frame 40 at the lower level to the information display frame 43 at the lowest level.

  Among these, the information display frame 40 displays an error type. Here, it is shown that the error is an overload among the head abnormalities together with the error code. The information display frame 41 below this one level displays the location where the error occurred. Further, the information display frame 42 at the lower level is an error countermeasure display frame for displaying an error countermeasure to be performed by the operator. Here, the text data “check component thickness” and “confirm suction position” read from the error countermeasure table 34 are displayed. Is displayed again in the expressions “Check the thickness of the part” and “Check the suction position”. The lowermost information display frame 43 displays the equipment state when an error occurs.

  Next, the flow of error processing in the electronic component mounting apparatus 1 from when a machine trouble occurs until error countermeasures are displayed will be described with reference to the flowchart of FIG. A machine trouble occurs during operation of the electronic component mounting apparatus 1 (ST1). The error countermeasure display control unit 31 identifies the type of error that caused the machine trouble (ST2). Moreover, the equipment state of the electronic component mounting apparatus 1 when a machine trouble occurs is specified (ST3). The error countermeasure search unit 36 searches the error countermeasure database 32 based on the error type and the equipment state specified by the error countermeasure display control unit 31 (ST4). The error countermeasure screen display unit 33 displays the error countermeasure information read from the error countermeasure table 34 by searching the error countermeasure database 32 on the touch panels 8 and 9 (ST5).

  The equipment control unit 30, the error countermeasure display control unit 31, the error countermeasure database 32, the error countermeasure screen display unit 33, and the error countermeasure search unit 36 constituting the electronic component mounting apparatus 1 are for the machine trouble that has occurred in the electronic component mounting apparatus 1. An error countermeasure display device 50 (see FIG. 3) that displays error countermeasures is configured. The error countermeasure display device 50 can be incorporated in a device other than the electronic component mounting device 1, for example, a printing device or a coating device for printing or applying an electronic component bonding agent such as solder on a substrate. It can be used as a device that informs the operator by visually displaying error countermeasures for the machine trouble that has occurred.

  According to the present invention, error countermeasures against machine troubles are stored in an error countermeasure storage unit in association with a combination of a plurality of patterns of equipment states and a plurality of patterns of error types, and equipment state information when a machine trouble occurs is stored. And necessary error countermeasure information based on the two types of information of the error type that caused the machine trouble is read from the error countermeasure storage unit and displayed visually, so that the calculation for error countermeasure display This has the advantage of simplifying the process and reducing the time taken from the occurrence of a trouble to the error countermeasure display, and is particularly useful in the mounting field where production is performed using a plurality of facilities in the apparatus.
