  Here, in the present embodiment, as illustrated in FIG. 1, the server 1 receives a plurality of component recognition data transmitted from the component mounting apparatus 2 on the transmission side by the communication unit 13 and accumulates it in the accumulation unit 12. It is configured as follows. Specifically, the server 1 is configured to accumulate not only a plurality of component recognition data of different types of components 20a but also a plurality of different component recognition data of the same type of components 20a.

  Moreover, in this embodiment, the control part 11 of the server 1 is comprised so that the parameter | index for selecting some component recognition data from the some component recognition data with respect to the same component 20a accumulate | stored may be shown. Specifically, the server 1 (control unit 11) is configured to rank and show some component recognition data based on a plurality of component recognition data for the same component 20a accumulated. That is, the server 1 (control unit 11) transmits an index for selecting component recognition data in response to a request from the receiving-side component mounting apparatus 2 or the PC 3, and displays the display unit of the receiving-side component mounting apparatus 2 27 or the display unit of the PC 3 is configured to display an index.

  The index for selecting the component recognition data includes, for example, the total number of times of recognition of the component 20a using the component recognition data, the recognition success rate, and the period when the component recognition data is used without being corrected. And the number of times the component recognition data has been imported from the server 1 to the component mounting apparatus 2. In addition, the control unit 11 is configured to rank and display some parts recognition data based on each index. For example, in the case of the display information example shown in FIG. 3, (ranking) information ranked based on the recognition success rate index is shown. In the example shown in FIG. 3, four component recognition data (NO. 1 to NO. 4) indices are displayed for the same component 20a. Further, when the component recognition data is selected by the user based on each index, the component recognition data such as the shape, dimension, dimensional tolerance, illumination level, threshold value, etc. of the component 20a is displayed.

  The server 1 (control unit 11) is configured to transmit component recognition data via the communication unit 13 in response to a request from the component mounting apparatus 2 or the PC 3 on the receiving side. The transmitted component recognition data is used to recognize the component 20a by the component mounting apparatus 2 or the PC 3 on the receiving side.

  Next, with reference to FIGS. 4 and 5, a process for evaluating the suitability of the component recognition data will be described.

  When the index of the component recognition data transmitted from the server 1 to the receiving side component mounting apparatus 2 or the PC 3 is displayed, the component recognition data is selected by the data user (user) in step S1 of FIG. The part recognition data import operation is performed. At this time, a plurality of component recognition data may be selected. In step S <b> 2, the component mounting apparatus 2 or the PC 3 accesses the database of the server 1. In step S3, the server 1 that has accessed the database transmits the component recognition data to the component mounting apparatus 2 or the PC 3, and causes the component mounting apparatus 2 or the PC 3 to import the component recognition data.

  When the suitability of the component recognition data is evaluated using the component mounting apparatus 2, an operation for sucking the component 20a by the component mounting apparatus 2 is performed by the data user in step S4. In step S5, the operated component mounting apparatus 2 sucks the component 20a and performs imaging of the sucked component 20a.

  When evaluating the suitability of the component recognition data using the PC 3, an image of the past component 20a that has been captured and stored in the PC 3 is used. That is, when the component mounting apparatus 2 is used, the component 20a corresponding to the component recognition data is actually picked up and imaged to evaluate the suitability of the component recognition data. On the other hand, when the PC 3 is used, the suitability of the component recognition data is evaluated based on an image captured in the past of the component 20a corresponding to the component recognition data.

  In step S6, an image of the component 20a is acquired in the component mounting apparatus 2 or the PC 3. In step S7, the data user performs a component recognition process execution operation. The operated component mounting apparatus 2 or PC 3 executes component recognition processing in step S8. Specifically, the recognition processing of the component 20a is performed based on the component recognition data received and imported from the server 1 in step S3 and the image of the component 20a acquired in step S6.

  In the component recognition process, for example, for the purpose of confirming the matching condition of the recognition data, a simple single recognition test (whether or not to recognize) is performed as the content of the recognition process. In this case, recognition success / failure, degree of matching of the defined shape of the component 20a, and an image obtained by superimposing the image of the component 20a and the defined shape are output as the component recognition trial results.

  Also, in the component recognition process, when the purpose is to confirm recognition robustness, the threshold value for determining the pixel value of the image and the setting of the illumination level at the time of imaging are changed as the recognition process content, and the recognition is performed multiple times. Is tried. In this case, the recognition success range (width) with respect to the threshold value and the illumination level setting at the time of imaging is output as the component recognition trial result. For example, as shown in FIG. 5, the result of successful recognition when the threshold value is changed is output based on the image of the component 20a whose illumination level is changed (levels 1 to 8) at the time of imaging. In this case, when the illumination level is level 4, the range (width) for recognizing the component 20a is increased. Therefore, if the illumination level is set to level 4 and t1 in the vicinity of the center of the threshold value that has been successfully recognized is set as the threshold value, even if there is a variation in the component 20a or a variation in imaging, the component can be reliably Component recognition data capable of recognizing 20a can be acquired.

  In the component recognition process, when the purpose is to confirm the recognition success rate, a plurality of recognitions are tried using the same component recognition data for a plurality of images of the component 20a. In this case, the recognition success number and the recognition success rate are output as the component recognition trial results.

  Note that the component recognition processing in step S8 of FIG. 4 may be tried in correspondence with a plurality of purposes among the above-mentioned purposes, or may be tried for each of a plurality of component recognition data.

  In step S9, the component recognition trial result is displayed by the component mounting apparatus 2 or the PC 3. In step S10, the data user who confirms the component recognition result determines the component recognition data to be adopted. In step S11, the data user performs an operation to reflect the part recognition data adopted in the production program. The operated component mounting apparatus 2 or PC 3 reflects (embeds) the adopted component recognition data in the production program in step S12. Steps S1 to S12 are repeated until the necessary part recognition data is evaluated and reflected in the production program.

  In the present embodiment, the following effects can be obtained.

Can be easily selected. Further, if the component recognition data is selected based on the recognition success rate, the component recognition data with high recognition accuracy of the component 20a can be easily selected. In addition, if the part recognition data is selected based on the period in which the part recognition data is used without being corrected, the part recognition data is considered to be used without being corrected in a long period of time and the degree of completion is high.
