  In step S8, it is displayed on the display of the terminal 42 that the component arrangement in the cassette is wrong (NG). In response to this display, the operator corrects the arrangement of the components in the cassette by changing the reels in the cassette so that they are in the correct arrangement.

  By executing the component mounting confirmation flow described above, the cassette and reel can be recognized while the component and reel are mounted on the cassette, and therefore, what components are stored in which reel position in the cassette. It is possible to correctly recognize whether or not it has been performed, and it is possible to mount the correctly recognized component on the printed circuit board, and as a result, it is possible to eliminate mounting errors. In addition, even if the actual machine mounter on the production line is in operation, it is possible to confirm the mounting position of the components in the cassette by executing the above component mounting confirmation flow away from the production line. And workability can be improved.

  FIG. 11 is a flowchart of cassette loading confirmation on a cart according to an embodiment of the present invention. The process of this flowchart is a process performed after loading a cassette in the cart as a cassette setup operation before actually mounting the part on the printed circuit board by the actual mounter, and the parts attached to a plurality of cassettes in the cart Is a process for confirming whether or not is installed in the correct cart lane position. If it is determined after the execution of this process that the cassette is not mounted at the correct lane position, the process of this flowchart is executed again after replacing the cassette in the cart.

  In step S11, the operator inputs from the terminal 43 the figure number of the printed board that designates the printed circuit board on which the component is to be mounted, and the mounter number that designates the mounter of the actual machine on which the component is mounted on this printed board. The component mounting information storage table shown in FIG. 9 can be transferred from the server 40 to the terminal 43 by the process of step S11. By referring to this table and executing the following processing steps, it is possible to determine whether or not the cassettes are correctly arranged in the cart.

  In step S <b> 12, the cart ID is acquired from the tag 88 by the automatic matching device 47. Since there are four carts to be mounted on the mounter of this embodiment shown in FIG. 1B, the cart is mounted in the mounter by obtaining the cart identification data (cart ID) stored in the tag attached to each cart. The position of each cart can be identified.

  In step S13, the collation lane range in the cart 87 is set. If there are four carts and each cart has 70 lanes, the lanes for the cart with cart ID 1 in the cart for checking whether the cassette arrangement in the cart is correct as the verification lane range 1 to 70, lanes 71 to 140 are set for a cart with a cart ID 2, lanes 141 to 210 are set for a cart with a cart ID 3, and lanes 211 to 280 are set for a cart with a cart ID 4.

  In step S <b> 14, the cassette ID and the part drawing number stored in the tag 86 of the cassette 80 are acquired by the automatic matching device 47. The antenna 85 in the automatic matching device 47 is self-propelled to read the tag 86, associate the position of the antenna 85 with the lane position on the cart 87, and further read information such as the cassette ID read by the antenna 85 and the antenna 85 at that time. By associating the position, it is determined which cassette is mounted at which lane position on the cart 87.

  In step S15, the cassette ID or component diagram in the component mounting information storage table stored in the server 40 is communicated with the server 40, and the cassette ID or component diagram acquired from the tag 86 in step S14 by the automatic verification device 47. The number is checked for each lane. By this processing, the cassette is stored in the cart by collating the cassette arrangement in the cart with the cassette used in the actual machine mounter and the cassette arrangement in the cart read by the automatic collating device 47. It can be confirmed whether or not the lane position is attached in the correct arrangement.

In step S16, if the collation results in step S15 match, it is determined that the cassette arrangement in the cart is correct, that is, the cassettes in the cart are arranged in the correct lane position, and the process proceeds to step S17. Then, it is determined that the cassettes in the cart are arranged in the wrong lane position, and the process proceeds to step S18.
In step S17, the display of the terminal 43 displays that the cassette arrangement in the cart is correct (OK).
In step S18, the display of the terminal 43 displays that the cassette arrangement in the cart is wrong (NG). In response to this display, the operator corrects the cassette arrangement in the cart by replacing the cassettes in the cart so that they are in the correct arrangement.

  By executing the cassette loading confirmation flow described above, the cassette ID and the component diagram number for identifying the cassette mounted on the plurality of lanes by reading the cassette ID and the component diagram number are read. Since the cassette ID or part diagram number in the part mounting information storage table that defines the arrangement of cassettes to be mounted on the cart used in the actual machine mounter is collated, when the cassette is mounted at the correct lane position in the cart Work time can be shortened and workability can be improved, and mistakes in mounting components on a printed circuit board due to work mistakes when mounting a cassette to a lane can be avoided. Furthermore, even when the actual machine mounter on the production line is in operation, the cassette loading position in the cart can be confirmed by executing the above cassette loading confirmation flow away from the production line, so that work efficiency is improved. And workability can be improved.

  In the embodiment described above, an example using a wireless IC tag and an antenna that receives data recorded on the wireless IC tag has been described. However, a barcode is used instead of the wireless IC tag, and a barcode reader is used instead of the antenna. May be used.
