The main body 20 has a transparent opening / closing cover 23 so that the work status can be confirmed.

  The main body 20 has a so-called dual line in which electronic components are taken out from different component supply carts 50 by two mounting heads and mounted on different substrates. In general, from the standpoint of safety, an open / close cover 23 is provided to prevent workers from accessing the apparatus during operation, and the left and right sides are independently centered around the center of the main body 20 like a bird's wing. It is designed to open and close. In the present embodiment, the operation cannot be started unless the two parts supply carts 50 are installed and the opening / closing cover 23 is closed.

Hereinafter, the configuration and operation of the electronic component mounting apparatus 100 mainly including the main body 20 will be described with reference to the drawings.
FIG. 2 is a plan view of the electronic component mounting apparatus 100 in which two component supply carts 50 are installed in the main body 20. There are component supply areas 3 in which the component supply cart 50 can be installed on both upper and lower sides of the paper surface of the electronic component mounting apparatus 100.

  The main body 20 has a drawing upper line and a drawing lower line of a center line CL indicated by a one-dot chain line, and mounts electronic components on the board P that has been independently conveyed by the board conveyor 7 of the conveying apparatus 2.

  Twelve suction nozzles 5 for sucking the electronic components are mounted on the circumference of the mounting head 6 for mounting the electronic components. The mounting head 6 picks up electronic components from a plurality of feeders 40 placed on the feeder fixing portion 53 of the component supply cart 50 installed in the component supply area 3, moves to a predetermined position on the substrate P, and mounts it.

  During the movement, the mounting head 6 recognizes the reference point of the substrate P at a predetermined position of the substrate P by the substrate recognition camera 8 provided, and electronic components are picked up based on the reference point of the substrate P. The position to be mounted on the substrate P can be determined. In addition, the mounting head 6 is imaged through the upper part of the component recognition camera 10 during its movement, and the suction state of the electronic component is inspected. If a suction abnormality is found, the electronic component is discharged into the discharge box 12. To do.

  In order to move the mounting head 6 as described above, the main body 20 has, for example, an X and Y moving mechanism constituted by a linear motor. The X moving mechanism includes an X stator (not shown) provided on the X beam 4A or 4B and an X mover 11 included in the mounting head. This is realized by moving freely on 4B. On the other hand, the Y moving mechanism is composed of a Y stator (not shown) provided on both sides of the Y beams 1A and 1B, and a mover 9 provided on both ends of the X beam 4A or 4B. The movement of the mounting head 6 is realized by the X beams 4A and 4B freely moving on the Y beams 1A and 1B.

  In the electronic component mounting apparatus 100 having the above-described configuration, the mounting head 6 sucks the electronic component from the feeder 40, moves to a predetermined position on the substrate P by the X, Y moving mechanism, and mounts the electronic component on the substrate P. To do. Some trouble may occur during this series of production operations, and the apparatus may be stopped in a state where a work-in-process substrate exists, and production may be interrupted. In this case, after the trouble has been resolved, it is necessary to resume production from the last step after mounting. This resumption of production operation after production interruption is hereinafter referred to as production resumption.

  FIG. 3 is a diagram showing an example of a restart confirmation screen 30 displayed on the monitor 21 shown in FIG. 1 when production is restarted. In the following description and FIG. 3, when indicating the mounting head 6 on the upper side of the paper and its related information shown in FIG. 2, the subscript A is added, and when showing the mounting head 6 on the lower side of the paper and its related information. Is suffixed with B. In addition, the suffixes A and B are not added when the contents of both mounting heads are shown and when the contents related to both mounting heads are shown.

  The restart confirmation screen 30 includes final mounting step information 31 that indicates the state of the final mounting step of the mounting head 6 at the time of production interruption, and mounting state information 32 that indicates the mounting state of the electronic component mounted on the substrate P by the mounting head 6. , A production resumption button 39a, a production resumption suspension button 39b for suspending production resumption, and an image adjustment button 39c for adjusting the image display of the mounting state information 32.

  The final mounting step information 31 further includes step information 37 representing information on the final mounting step of the mounting head 6 at the time of production interruption, and mounting setting information 38 for instructing mounting of the electronic component and holding the instruction content. In the present embodiment, the step information 37 includes electronic component mounting position information 33 and component information 34 indicating information on the mounted electronic component. On the other hand, the mounting setting information 38 determines whether or not an electronic component is mounted based on the mounting state information 32, and a button 35 for mounting and a button for not mounting that the operator touches to determine the mounting setting of “mounting / not mounting”. 36. The component information 34 includes the number of the feeder 40 that supplied the electronic component and the component ID, and the mounting position information 33A of the mounting head 6A is F217 and C1005T05B0-12345, respectively. Reference numeral 39b denotes a cancel button. When this button is touched, the display of the restart confirmation screen is temporarily ended.

  In FIG. 3, the mounting head 6A is being mounted at the time of production interruption or immediately after processing. Therefore, in order to ask the operator to determine whether or not there is mounting, mounting position information 33A and part information 34A as step information 37A are displayed. Further, the button 35A for mounting and the button 36A for not mounting setting which are the mounting setting information 38A for easy understanding of the selection contents are highlighted in red. On the other hand, since the mounting head 6B is not subjected to mounting processing when production is interrupted, the final mounting step information 31B is not displayed or highlighted.

Next, a processing flow for resuming production in the embodiment of the present invention will be described with reference to FIG. The description will be made based on the example shown in FIG.
When the operator operates a start switch (not shown) after the production interruption occurs, first, data for displaying the resumption confirmation screen 30 shown in FIG. 3 is automatically generated and displayed (Step 1 (hereinafter abbreviated as S1; hereinafter the same). )). Next, it is determined whether it is necessary to determine the mounting setting of “mounting / not mounting” for the mounting head 6A. The determination is made based on whether the final mounting step information exists in the final mounting step information 31A column of the restart confirmation screen 30 (S2). In the example of FIG. 3, since final mounting step information 31A of the mounting head 6A exists, the process goes to S3. If not, the process goes to S7 to determine the mounting head 6B.

  In the next S3, the operator determines whether or not to “wear”. If the electronic component to be mounted is already mounted on the substrate P, the electronic component is shown in the imaging screen displayed in the mounting state information 32 column. Conversely, when the electronic component is not mounted, the electronic component is not shown on the imaging screen. Therefore, the determination is made based on the presence / absence of an imaging screen of the electronic component. In the example of FIG. 3, since an imaging screen for electronic parts exists, the process proceeds to S4 and the button 36A that is not to be mounted is selected. If there is no electronic part imaging screen, go to S5 and select the button 35A to be mounted. After the selection, the selected button is changed from red to light blue, and the unselected button is changed from red to white so that the selected contents are highlighted. The imaging screen is obtained by the board recognition camera 8 fixed to the mounting head 6 shown in FIG. Alternatively, a predetermined pattern may be displayed if wearing is confirmed by imaging.

  The same processing as that for the mounting head 6A is performed for the mounting head 6B in S7 to S11. Next, the entire resumption confirmation screen 30 shown in FIG. 3 (for example, a screen shot of the entire displayed screen) is stored in the memory constituting the storage means built in the control device 28 (S12). Thereafter, after waiting for the cancellation of the production interruption factor (S13), the production resumption button 39a is touch-selected (S14), and the production operation is resumed. The cause of the production interruption may be canceled before the operator operates a start switch (not shown) after the production interruption occurs.

FIG. 5 shows a search process flow of the cause when a missing substrate on which no electronic component is mounted after production resumes.
First, the position of the missing part on the board (hereinafter referred to as a missing part) is grasped and input as missing part information (S1). Next, it is determined whether or not production is interrupted (S2). If there is a production interruption, the corresponding resumption confirmation screen 30 at the start of production is displayed again (S3). It is checked whether the position of the missing item matches the mounting position information 33 on the restart confirmation screen 30 (S4). If they do not match, the process returns to S1 to see if there is any other production interruption. If they match, the presence / absence of an electronic component imaging screen is checked in the mounting state information 32 column (S5). If there is an electronic component imaging screen, the display of the imaging screen is incorrect (S8). If there is no electronic component imaging screen, the mounting setting information is viewed (S6). If the button 35 to be mounted is light blue and “install” is selected, there is a problem with the apparatus itself that performs the mounting process. (S9). On the other hand, if the button 36 that is not mounted is light blue, that is, if it is selected that the button is not mounted, an operator selection error occurs (S7). In the above search processing flow, if there is no production interruption, or if the mounting position information 33 on the resumption confirmation screen 30 in all production interruptions is different from the missing item position, the cause of the missing item has nothing to do with production interruption. Is a problem of the operation of the apparatus itself (S9).

  The search processing is performed by a processing program (search means) built in the control device 28. In addition, among the causes of missing parts, erroneous display on the imaging screen is extremely rare. Therefore, S5 may be omitted from the above steps. Furthermore, if it is determined that the operation of the apparatus itself is a problem, the cause of this problem can be obtained by other methods.

  In the above description, the position of the missing item is input as the missing item information. Therefore, mounting position information 33 is provided as final mounting step information 31 to be searched. However, indirectly, other information may be used as long as the missing part position can be recognized as the final mounting step information 31. For example, the component library data for mounting the electronic component includes the mounting order and mounting position of the electronic component. Therefore, the mounting order can be used as the final mounting step information 31.

  In the above description, the position of the missing item is input as the missing item information. However, if the electronic component has a characteristic or the number of mounting points is small, the component ID can be used as the missing item information. In that case, the component ID can be used as the final mounting step information 31.

  In short, it is only necessary that the shortage information and the final mounting step information 31 are directly or indirectly in a one-to-one relationship or to a certain degree.

  In the above description, the control device 28 automatically determines S4, S5, and S6. However, the operator may make a determination using a man machine.

  According to the embodiment described above, the resumption confirmation screen 30 is stored, and when the shortage occurs, the resumption confirmation screen stored again is displayed, thereby clarifying the selection contents of the operator when resuming production. Thus, the cause of the shortage can be solved at an early stage, and an electronic component mounting apparatus and an electronic component mounting method having a high operating rate can be provided.

  Although the embodiments of the present invention have been described above, various alternatives, modifications, and variations can be made by those skilled in the art based on the above description, and the present invention is not limited to the various embodiments described above without departing from the spirit of the present invention. It encompasses alternatives, modifications or variations.
