Abstract

PROBLEM TO BE SOLVED: To mainly make it possible to correctly recognize a component by suppressing erroneous recognition of components caused by component data showing that terminal sizes and inter-terminal pitches of existing terminals of the components are approximately the same and their numbers of terminals are different.SOLUTION: When a plurality of pieces of component data show that position coordinates and terminal sizes of existing terminals of the pieces of component data are approximately the same and their numbers of terminals are different, a virtual terminal definition for defining the absence of a terminal in one piece of component data is added to a position at which no terminal exists in the one piece of component data and a terminal exists in another piece of component data. In the case of performing picture processing on an imaged picture of a component P by using a piece of component data to which a virtual terminal definition is added, it is determined that the picture processing is successful when it is recognized that terminals exist at all positions having a terminal definition and it is recognized that no terminal exist at all positions having a virtual terminal definition. Thereby, identification of a plurality of component similar to each other is enabled, making it possible to prevent erroneous recognition of components.SELECTED DRAWING: Figure 9

By the way, bump parts and lead parts such as BGA (Ball grid array) and QFP (Quad Flat Package) have substantially the same terminal size and terminal position (or pitch between terminals). There are several things that differ. For this reason, when recognizing a component terminal (feature) from a captured image, a terminal having a size specified by the component data is specified on the specified terminal position (or on the inter-terminal pitch) in the captured image. Depending on whether or not the number of terminals can be recognized, the type of component can be identified. However, depending on the imaging conditions, the appearance of some terminals may be unclear and the terminals may not be recognized, or those similar objects may be misrecognized as terminals due to the reflection of marks or wiring patterns attached to parts. In some cases, it is not easy to correctly recognize the terminals (features).

The present invention mainly suppresses misrecognition of components due to component data in which the terminal size and pitch between terminals or terminal positions of existing terminals are substantially the same and the number of terminals is different, so that the components can be recognized correctly. And

As shown in FIG. 2, the substrate transfer device 30 is configured as a dual-lane transfer device provided with two substrate transfer paths in this embodiment. The substrate transfer device 30 is installed at the center in the front-rear direction (Y-axis direction) of the support base 14. Moreover, the board | substrate conveyance apparatus 30 is provided with the belt conveyor apparatus 32, and the board | substrate S is conveyed from the left of FIG. A backup plate 34 that can be lifted and lowered by a lifting device (not shown) is provided at the center of the substrate transporting device 30 in the substrate transporting direction (X-axis direction). When the substrate S is transported above the backup plate 34 by the substrate transport device 30, the backup plate 34 is raised by driving the lifting device to back up the substrate S from the back surface side.

As shown in FIG. 3, the head 50 includes a Z-axis actuator 52 that moves the suction nozzle 51 in the Z-axis (up and down) direction, and a θ-axis actuator 54 that rotates the suction nozzle 51 around the Z-axis. The suction port of the suction nozzle 51 is selectively communicated with either the vacuum pump 58 or the air pipe 59 via the electromagnetic valve 57. The control device 70 drives the electromagnetic valve 57 so that the suction port of the suction nozzle 51 communicates with the vacuum pump 58, so that negative pressure is applied to the suction port and the component P can be sucked.

The parts camera 60 is disposed on the support base 14 on the front side of the substrate transfer apparatus 30. When the part P sucked by the suction nozzle 51 passes above the part camera 60, the parts camera 60 images the part P and outputs the obtained captured image to the control device 70. The control device 70 performs image processing on the captured image captured by the parts camera 60 to identify whether or not the component P sucked by the suction nozzle 51 is a correct component, or the component P is a suction nozzle.

The second illumination device 68 is used as illumination when the component P images a bump component having a bump (hemispherical) terminal such as BGA. Thereby, illumination light can be uniformly applied to the bump terminals, and a good captured image can be obtained. For example, a CCD (charge coupled device) or a CMOS (complementary metal oxide semiconductor) can be used as the imaging device 62.

The control device 70 is configured as a microprocessor centered on the CPU 71, and includes a ROM 72, an HDD 73, a RAM 74, and an input / output interface 75 in addition to the CPU 71. These are electrically connected via a bus 76. The control device 70 includes a position signal from the X axis position sensor 47 that detects the position of the X axis slider 42, a position signal from the Y axis position sensor 49 that detects the position of the Y axis slider 44, and a mark camera 56. An image signal, an image signal from the parts camera 60, and the like are input via the input / output interface 75. On the other hand, the control device 70 moves the control signal to the component supply device 20, the control signal to the substrate transfer device 30, the drive signal to the X-axis actuator 46 that moves the X-axis slider 42, and the Y-axis slider 44.

In addition, the control device 70 is connected to the management device 80 so as to be capable of bidirectional communication, and exchanges data and control signals with each other.

The management device 80 is, for example, a general-purpose computer, and includes a CPU 81, a ROM 82, an HDD 83, a RAM 84, an input / output interface 85, and the like. These are electrically connected via a bus 86. An input signal is input to the management apparatus 80 via an input / output interface 85 from an input device 87 such as a mouse or a keyboard. Further, an image signal to the display 88 is output from the management device 80 via the input / output interface 85. The HDD 83 stores a production plan for the substrate S. Here, the production plan of the board S defines which parts are to be mounted on the board S in which order in each component mounting machine 10, and how many boards S on which such parts are mounted are produced. Plan. This production plan includes substrate data relating to the substrate to be produced, head data relating to the head 50 to be used, nozzle data relating to the suction nozzle 51 to be used, component data relating to the component to be mounted, mounting position data relating to the mounting position of each component, and the like. ing. The management apparatus 80 creates a production plan based on data (production number, board data, component data, mounting position data, etc.) input by the operator via the input device 87, and the created production plan is stored in each component mounting machine 10. Send to.

FIG. 5 is an explanatory diagram showing an example of component data stored in the HDD 83. The component data is input by the operator using the input device 87 and is stored in the HDD 83 each time. As shown in the figure, the component data includes a component type indicating the type of the component P such as a bump component or a lead component, a body size indicating the external size of the component P, and a size (terminal diameter) of a terminal (bump terminal or lead terminal). The terminal size, the number of terminals, the position coordinates of each terminal, the pitch between terminals, and the like are included. The component data also includes a terminal definition that defines the presence of a terminal depending on the position coordinates of each terminal and the pitch between terminals. Furthermore, virtual part definitions may be added to the component data. The virtual terminal definition defines that no terminal exists at a specified position, and is added to the component data by a component data creation process described later. Although the details of the terminal definition and virtual terminal definition of the component data will be described later, the type of the component P is identified from the captured image obtained by capturing the component P sucked by the suction nozzle 51 with the parts camera 60 before the mounting. Used when

Next, the operation of the component mounting system 1 (component mounter 10) of the embodiment configured as described above will be described. FIG. 6 is a flowchart illustrating an example of a component mounting process executed by the CPU 71 of the control device 70. This process is executed when the start of production is instructed by the operator. The control device 70 receives the production plan transmitted from the management device 80, and executes component mounting processing according to the received production plan.

When the component mounting process is executed, the CPU 71 of the control device 70 first performs a suction operation for sucking the component P supplied from the component supply device 20 to the suction nozzle 51 (S100). Here, the suction operation is specifically performed by controlling the XY robot 40 so that the suction nozzle 51 mounted on the head 50 comes directly above the component P, and then the suction nozzle until the suction port contacts the component P. The Z-axis actuator 52 is driven and controlled so that 51 descends, and the electromagnetic valve 57 is driven and controlled so that a negative pressure acts on the suction port of the suction nozzle 51. Subsequently, the CPU 71 drives and controls the XY robot 40 so that the part P sucked by the suction nozzle 51 moves above the parts camera 60 (S110), and images the part P with the parts camera 60 (S120).

Next, the CPU 71 acquires part data related to production from the received production plan (S130), and uses the acquired part data to image the image illustrated in FIG. 7 with respect to the captured image obtained in S120. Processing is performed (S140). Here, the description of the component mounting process is interrupted, and the details of the image processing will be described.

When the image processing is executed, the CPU 71 acquires the acquired component data definition (terminal definition, virtual terminal definition) (S200), and determines whether the acquired definition includes a virtual terminal definition (S210). ). If the CPU 71 determines that the virtual terminal definition is not included, the CPU 71 searches for a peripheral pixel at a position with the terminal definition in the captured image captured at S120 of the component mounting process (S220), and sets the terminal at all the positions with the terminal definition. It is determined whether or not it has been recognized (S230). Specifically, the process of S220 is a process of extracting the pixel values (luminance values) of the peripheral pixels at the position where the terminal definition is present, and the process of S230 is specifically the extracted pixel value equal to or greater than the threshold value. This is a process for determining whether or not there is. Here, the component P is usually subjected to low reflection processing so that reflection of irradiation light is suppressed. For this reason, the captured image obtained by imaging the part P is an image in which the terminal portion appears white and the other body portions appear black. Therefore, when the pixel value at a certain position of the terminal definition is equal to or greater than the threshold value, it can be determined that the pixel is a pixel in which the terminal is reflected. However, when a mark, a character, a logo, or the like is attached to the component P, these also appear whitish, so the pixel value of the pixel in which they appear may be equal to or greater than a threshold value. In this embodiment, by narrowing down to peripheral pixels at a position with a terminal definition and determining whether or not the pixel value is equal to or greater than a threshold value, a mark other than a terminal, a character, a logo, or the like is erroneously recognized as a terminal. It is preventing this.

If the CPU 71 determines in S230 that it has recognized that the terminal exists at all the positions where the terminal is defined, it determines that the image processing has been successful (determines that the component P sucked to the suction nozzle 51 is a correct component. (S240), the image processing is terminated, and if it is determined that the presence of a terminal cannot be recognized at any one of the positions with the terminal definition, it is determined that the image processing has failed (the suction nozzle 51 is sucked). The determined part P is determined not to be a correct part) (S250), and the image processing is terminated.

FIG. 8 is an explanatory diagram for explaining how image processing is performed on a captured image using component data. As shown in the figure, when image processing is performed on a captured image obtained by imaging the bump component B using the component data of the bump component B, terminals are present at all positions where the terminal definition is present as illustrated. Therefore, the image processing is successful. On the other hand, using the same bump component B component data, the bump component A having the same position coordinates (inter-terminal pitch) and terminal size where the bump component B and the terminal are present and the number of terminals is imaged. Even when image processing is performed on a captured image, since it is recognized that terminals exist at all positions where the terminal definition exists, the image processing succeeds. That is, with only the terminal definition of the component data of the bump component B, since the image processing is successful for both the bump component A and the bump component B, the bump component may not be recognized correctly.

When determining that the virtual terminal definition is included in the definition acquired in S210, the CPU 71 searches for a peripheral pixel at a position where the terminal definition exists in the captured image, similarly to S220 and S230 (S260). It is determined whether or not it has been recognized that a terminal exists at all of certain positions (S270). If the CPU 71 determines that the terminal exists at all the positions with the terminal definition, then the CPU 71 searches for a peripheral pixel at the position with the virtual terminal definition in the captured image (S280). It is determined whether or not it can be recognized that there is no terminal at all the positions (S290). The process of S280 is specifically a process of extracting pixel values (luminance values) of peripheral pixels at a position where the virtual terminal is defined, and the process of S290 is specifically the extracted pixel value is less than the threshold value. It is the process which determines whether it is. If the CPU 71 determines that the terminal does not exist at all positions where the virtual terminal definition exists, the CPU 71 determines that the image processing is successful (S240), and ends the image processing. The CPU 71 determines that the terminal exists at any one of the positions with the terminal definition in S270, or determines that the terminal does not exist at any one of the positions with the virtual terminal definition in S290. If it is determined that the image could not be recognized, it is determined that the image processing has failed (S295), and the image processing is terminated.

FIG. 9 is an explanatory diagram illustrating a state in which image processing is performed on a captured image using component data to which a virtual terminal definition is added. As shown in the figure, when image processing is performed on a captured image obtained by imaging the bump component B using the component data of the bump component B, terminals are present at all positions where the terminal definition is present as illustrated. Since it is recognized that there is no terminal at any position where the virtual terminal definition exists, the image processing succeeds. On the other hand, by using the same component data of the bump component B, a bump component A having the same terminal position coordinates (inter-terminal pitch) and terminal size where the bump component B and the terminal exist and the number of terminals is the same. When image processing is performed on a captured image, it is recognized that terminals exist at all positions with terminal definitions, but it is recognized that terminals also exist at positions with virtual terminal definitions. Therefore, the image processing fails. As described above, by adding the virtual terminal definition to the component data, it is possible to identify a plurality of bump components having the same terminal position coordinates (inter-terminal pitch) and terminal size but different numbers of terminals.

Returning to the component mounting process, when the CPU 71 performs the image processing in S140, the CPU 71 determines whether the image processing is successful (S150). If the CPU 71 determines that the image processing has failed, it outputs an error (S160) and ends the component mounting process. Note that the process of S160 is performed by transmitting error information regarding a component difference error to the management apparatus 80. The management device 80 that has received the error information displays a warning screen on the display 88 and emits a warning sound, thereby notifying the operator of a component difference error. On the other hand, if the CPU 71 determines that the image processing is successful, the CPU 71 calculates the amount of suction displacement of the component P based on the captured image (S170), and corrects the mounting position based on the calculated amount of suction displacement (S180). Then, a mounting operation for mounting the component P sucked by the suction nozzle 51 on the mounting position of the substrate S is performed (S190), and the component mounting process is ended. Here, the mounting operation is specifically performed by driving and controlling the XY robot 40 so that the component P sucked by the suction nozzle 51 is directly above the mounting position of the substrate S, and then the component P is mounted on the substrate S. The Z-axis actuator 52 is driven and controlled so that the suction nozzle 51 descends until it comes into contact with the position, and the electromagnetic valve 57 is driven and controlled so that a positive pressure acts on the suction port of the suction nozzle 51.

Next, a part data creation process for creating part data to which a virtual terminal definition is added will be described. The creation of the component data is performed by the management device 80 based on the data input by the operator. FIG. 10 is a flowchart illustrating an example of component data creation processing executed by the CPU 81 of the management device 80.

When the part data creation process is executed, the CPU 81 of the management device 80 first selects one target data from the unprocessed part data group stored in the HDD 83 (S300), and the target data and the body size are selected. And similar data having a similar terminal size (substantially the same) is extracted from the component data group stored in the HDD 83 (S310). The process of S310 is a process of searching for and extracting component data in which the size differences between the body size and the terminal size from the target data are both within the error range. When the similar data is extracted in this way, the CPU 81 selects one comparison data from the unprocessed data among the extracted similar data (S320), and is illustrated in FIG. 11 using the selected target data and comparison data, respectively. The difference extraction process is executed to create component data to which the virtual terminal definition is added (S330).

When the difference extraction process of FIG. 11 is executed, the CPU 81 of the management device 80 generates a component image similar to the captured image by laying out the terminal image according to the definition of the target data (terminal definition) (S400). Subsequently, the CPU 81 generates a component image similar to the captured image by laying out the terminal image in accordance with the definition of the comparison data (terminal definition) (S410), and defines the target data for the generated component image of the comparison data. Then, the image processing shown in FIG. 7 is performed (S420). When the CPU 81 determines that the image processing is successful as a result of the image processing (S430), the CPU 81 generates a difference image by taking the difference between the component image of the comparison data generated in S410 and the component image of the target data generated in S400. Then, a virtual terminal definition is added at a position (difference position) where there is a difference image with respect to the target data (part data in which the virtual terminal definition is added to the target data is created) (S450), and the difference extraction process is performed. finish. On the other hand, if the CPU 81 determines that the image processing has failed in S430, the CPU 81 performs the image processing shown in FIG. 7 in the definition of comparison data for the component image of the target data generated in S400 (S460). If the CPU 81 determines that the image processing is successful as a result of the image processing (S470), the CPU 81 generates a difference image by taking the difference between the component image of the target data generated in S400 and the component image of the comparison data generated in S410. Then, a virtual terminal definition is added to a position (difference position) where there is a difference image with respect to the comparison data (part data in which the virtual terminal definition is added to the comparison data is created) (S490), and the difference extraction process is performed. finish. If the CPU 81 determines that the image processing has failed in S470, the CPU 81 ends the difference extraction processing without adding a virtual terminal definition.

Returning to the component data creation process, when the CPU 81 creates the component data by the difference extraction process in S330, the comparison data is set to the processed similar data (S340), and then whether there is unprocessed similar data or not. Is determined (S350). If the CPU 81 determines that there is unprocessed similar data, the CPU 81 returns to S320, selects one new comparison data, repeatedly executes the processes of S330 and S340, and determines that there is no unprocessed similar data. The target data is set as processed part data (S360), and then it is determined whether there is any other unprocessed part data that can become target data (S370). If the CPU 81 determines that there is other unprocessed component data, the CPU 81 returns to S300, selects new one target data, repeatedly executes the processing of S310 to S360, and there is no other unprocessed component data. If it is determined, the part data creation process is terminated.

FIG. 12 is an explanatory diagram showing a state in which component data to which a virtual terminal definition is added is created. As shown in the figure, the terminal definition of the bump component B is defined for the component image of the bump component A having the same position coordinates (or inter-terminal pitch) and terminal size as the bump component B and the terminal size and a large number of terminals. If the image processing of S420 or S460 of the difference extraction processing is performed, the image processing is successful. Therefore, a difference image is generated by taking the difference between the component image of the bump component A and the component image of the bump component B in S440 or S480 of the difference extraction process. The difference image is a terminal image representing a terminal that exists only in the bump component A. Therefore, a virtual terminal definition that defines that no terminal exists at the difference position is added to the component data of the bump component B. As a result, as shown in FIG. 9 described above, when image processing is performed on the captured image obtained by capturing the bump component B using the component data of the bump component B, the image processing can be successful. When image processing is performed on a captured image obtained by capturing the bump component A using the component data, the image processing can be failed.

The component mounting system 1 of the embodiment described above extracts a plurality of component data in which the position coordinates (or inter-terminal pitch) and terminal sizes of existing terminals are substantially the same and the number of terminals is different. Thereby, it is possible to extract a plurality of component data that may be erroneously recognized. By using the extracted component data, it is possible to suppress erroneous recognition of the component P to be mounted and to recognize the component P correctly. Can do.

In addition, the component mounting system 1 of the embodiment does not exist in one component data among a plurality of component data in which the position coordinates (or pitch between terminals) and the terminal sizes of the existing terminals are substantially the same and the number of terminals is different. A virtual terminal definition that defines that no terminal exists for the one component data is added to the position (difference position) of the terminal that exists in the other component data. When image processing is performed on the captured image of the component P using the component data to which the virtual terminal definition is added, it is recognized that the terminal exists at all positions where the terminal definition exists, and there is a virtual terminal definition. By recognizing that image processing has been successful when it is recognized that there are no terminals at all positions, a plurality of similar parts can be identified, and erroneous recognition of parts can be prevented. . In addition, the component mounting system 1 according to the embodiment narrows the range for recognizing the terminal to a position where the terminal definition is present and a position where the virtual terminal definition is present, thereby reflecting a mark or a wiring pattern attached to the component P. Can be prevented from being erroneously recognized as a terminal.

In the embodiment, in the difference extraction process of FIG. 11, a component image is generated according to the comparison data definition, image processing is performed with the target data definition for the generated comparison data component image, and the component image is defined according to the target data definition. And the image processing is performed with the definition of the comparison data on the component image of the generated target data, so that the position coordinates and the pitch between the terminals existing between the target data and the comparison data are substantially the same. It is determined whether or not there is, but the present invention is not limited to this, and it exists between these by directly comparing the position where the target data is defined and the position where the comparison data is defined. It is good also as what determines whether the position coordinate of terminals and the pitch between terminals are substantially the same.

In the embodiment, the virtual terminal definition is automatically added to the component data by executing the component data creation processing of FIG. 10, but the present invention is not limited to this. For example, by executing the component data creation process of the modified example illustrated in FIG. 13, similar data having similar terminal sizes and terminal position coordinates (or inter-terminal pitches) is searched for and displayed in a list. Further, it is possible to support additional input of the virtual terminal definition by the operator.

When the component data creation process of FIG. 13 is executed, the CPU 81 of the management device 80 selects one target data from the unprocessed component data group among the component data stored in the HDD 83 (S500). Similar data is extracted that is close (substantially the same) to the selected target data and whose terminal size and position coordinates (or inter-terminal pitch) are close to each other and whose body size is close to each other (S510). Then, the CPU 81 sets the target data as the selected part data (S520), and determines whether there is unselected part data (S530). If the CPU 81 determines that there is unselected component data, the CPU 81 returns to S500, selects new one target data, and repeatedly executes the processing of S510 and S520. On the other hand, if the CPU 81 determines that there is no unselected component data, the CPU 81 displays a list of component data for each similar data similar to each other (S540). FIG. 14 is an explanatory diagram showing an example of the component data display screen 90. The component data display screen 90 is associated with a component data display area 92 for displaying similar data (component images) having substantially the same size and position coordinates (or inter-terminal pitch) in thumbnail format for each similar data. A detailed display instruction for calling up a tab area 94 in which a plurality of tabs are arranged and details of the component data displayed in the component data display area 92 (for example, detailed display of component type, body size, terminal size, number of terminals, etc.) Region 96. Switching of component data (similar data) to be displayed in the component data display area 92 can be performed by placing the cursor on one of the plurality of tabs in the tab area 94 and clicking the mouse.

Then, the CPU 81 determines whether or not a part data selection operation has been performed by the operator (S550) and whether or not a virtual terminal addition operation has been performed (S560). If it is determined that a terminal input operation has been performed, a virtual terminal definition is added at the input position of the selected component data (S570), and the component data creation process is terminated. FIG. 15 is an explanatory diagram showing how a virtual terminal definition is added to component data using the component data display screen 90. As shown in the figure, the virtual terminal definition is added by placing the cursor 98 on the position where the operator wants to add the virtual terminal definition and clicking the mouse (see FIGS. 14A and 14B). "Can be performed by clicking the mouse (see FIG. 14C). The addition of the virtual terminal definition can be canceled by setting the cursor 98 to “No” and clicking the mouse.
