Mode for Carrying Out the Invention

[0009] Hereinafter, as a mode for carrying out the present invention, examples of the present invention will be described in detail with reference to the drawings.

[0010] FIG. 1 shows a component mounter 10. The component mounter 10 is a device for performing component mounting work on a circuit substrate 12. The component mounter 10 includes a device main body 20, a substrate conveyance and holding device 22, a component mounting device 24, a mark camera 26, a parts camera 28, a loose component supply device 30, a component supply device 32, and a control device (see FIG. 3) 36. Examples of the circuit substrate 12 include a circuit board and a three-dimensional structure substrate, and examples of the circuit board include a printed wiring board and a printed circuit board.

[0011] The device main body 20 is composed of a frame 40 and a beam 42 mounted on the frame 40. The substrate conveyance and holding device 22 is disposed at the center in the front-rear direction of the frame 40 and has a conveyance device 50 and a clamp device 52. The conveyance device 50 is a device for conveying the circuit substrate 12, and the clamp device 52 is a device for holding the circuit substrate 12. Thereby, the substrate conveyance and holding device 22 conveys the circuit substrate 12 and fixedly holds the circuit substrate 12 at a predetermined position. In the following description, the conveyance direction of the circuit substrate 12 is referred to as the X direction, the horizontal direction perpendicular to that direction is referred to as the Y direction, and the vertical direction is referred to as the Z direction. That is, the width direction of the component mounter 10 is the X direction, and the front-rear direction is the Y direction.

[0012] The component mounting device 24 is disposed on the beam 42 and has two work heads 60, 62 and a work head moving device 64. Each work head 60, 62 has a suction nozzle (see FIG. 2) 66 and holds a component by the suction nozzle 66. As shown in FIG. 2, the work head moving device 64 has an X-direction moving device 68, a Y-direction moving device 70, and a Z-direction moving device 72. Then, by the X-direction moving device 68 and the Y-direction moving device 70, the two work heads 60, 62 are integrally moved to an arbitrary position on the frame 40. Further, each work head 60, 62 is detachably attached to sliders 74, 76, and the Z-direction moving device 72 individually moves the sliders 74, 76 in the vertical direction. That is, the work heads 60, 62 are individually moved in the vertical direction by the Z-direction moving device 72.

[0013] As shown in FIG. 2, the mark camera 26 is attached to the slider 74 in a downward-facing state and is moved in the X-direction, Y-direction, and Z-direction together with the work head 60. Thereby, the mark camera 26 images an arbitrary position on the frame 40. Further, as shown in FIG. 1, the parts camera 28 is disposed between the base material conveying and holding device 22 and the component supply device 32 on the frame 40 in an upward-facing state. Thereby, the parts camera 28 images the components held by the suction nozzles 66 of the work heads 60, 62.

[0014] The loose component supply device 30 is disposed at one end of the frame 40 in the front-rear direction. The loose component supply device 30 is a device that aligns a plurality of components scattered in a scattered state and supplies the components in an aligned state. That is, it is a device that aligns a plurality of components in an arbitrary posture to a predetermined posture and supplies the components in the predetermined posture.

[0015] The component supply device 32 is disposed at the other end of the frame 40 in the front-rear direction. The component supply device 32 has a tray-type component supply device 86 and a feeder-type component supply device 88. The tray-type component supply device 86 is a device that supplies components placed on a tray (not shown). The feeder-type component supply device 88 is a device that supplies components by a tape feeder 90.

[0016] As shown in FIG. 3, the control device 36 includes a controller 100, a plurality of drive circuits 102, an image processing device 104, and a control circuit 106. The plurality of drive circuits 102 are connected to the transport device 50, the clamp device 52, the work heads 60, 62, the work head moving device 64, the tray-type component supply device 86, the feeder-type component supply device 88, and the loose component supply device 30. The controller 100 includes a CPU, a ROM, a RAM, etc., and is mainly a computer, and is connected to the plurality of drive circuits 102. Thereby, the operations of the base material transport and holding device 22, the component mounting device 24, etc. are controlled by the controller 100. Also, the controller 100 is connected to the image processing device 104. The image processing device 104 processes the image data obtained by the mark camera 26 and the parts camera 28, and the controller 100 acquires various information from the image data. Further, the controller 100 is connected to the display device 108 via the control circuit 106. Thereby, an arbitrary image is displayed on the display device 108 by the controller 100. Note that a production program 110 is stored in the controller 100, and the controller 100 controls the operations of the base material transport and holding device 22, the component mounting device 24, etc. according to the production program 110 to execute the component mounting operation on the circuit board 12. In the component mounter 10, various components can be mounted on the circuit board 12. The case of mounting a lead component (see FIG. 4) 120 on the circuit board 12 will be described below.

[0017] Specifically, according to the command of the controller 100 in accordance with the production program 110, the substrate transfer and holding device 22 transfers the circuit substrate 12 to the working position, and at that position, the clamping device 52 fixedly holds the circuit substrate 12. Next, according to the command of the controller 100 in accordance with the production program 110, the mark camera 26 moves above the circuit substrate 12 and images the circuit substrate 12. Thereby, the controller 100 acquires information regarding the positions of a pair of through holes (see FIG. 4) 122 formed in the circuit substrate 12. The through holes 122 are round holes with a circular cross-sectional shape, and the inner diameter of the through holes 122 is larger than the outer diameter of the leads (see FIG. 4) 128 of the lead component 120 by a predetermined dimension.

[0018] Also, according to the command of the controller 100 in accordance with the production program 110, the discrete component supply device 30 or the component supply device 32 supplies the lead component 120 at a predetermined supply position. As shown in FIG. 4, the lead component 120 generally includes a block-shaped component body 126 and two leads 128 extending from the bottom surface of the component body 126. Then, according to the command of the controller 100 in accordance with the production program 110, either of the working heads 60, 62 moves above the component supply position, and the suction nozzle 66 sucks and holds the component body 126 of the lead component 120. Subsequently, according to the command of the controller 100 in accordance with the production program 110, the working heads 60, 62 move above the parts camera 28, and the parts camera 28 images the lead component 120 held by the suction nozzle 66. Thereby, information regarding the tip positions of the pair of leads 128 is obtained. Subsequently, according to the command of the controller 100 in accordance with the production program 110, the working heads 60, 62 move above the circuit substrate 12, and the holding posture of the held component is adjusted based on information such as the position of the through holes 122 formed in the circuit substrate 12 and the tip positions of the leads 128 of the lead component 120 held by the suction nozzle 66. At this time, the movement and the adjustment of the holding posture of the working heads 60, 62 are performed so that the positions of the pair of through holes 122 formed in the circuit substrate 12 and the tip positions of the pair of leads 128 of the lead component 120 held by the suction nozzle 66 coincide in the vertical direction within the horizontal plane.

[0019] Then, in response to the commands of the controller 100 according to the production program 110, when the work heads 60, 62 move so that the positions of the pair of through holes 122 and the tip positions of the pair of leads 128 are aligned in the vertical direction, the work heads 60, 62 descend. As a result, as shown in FIG. 4, the tip portions of the pair of leads 128 of the lead component 120 are inserted into the pair of through holes 122 of the circuit base material 12. In this way, in the component mounter 10, the lead component 120 is mounted on the circuit base material 12 by inserting the leads 128 of the lead component 120 into the through holes 122 of the circuit base material 12.

[0020] However, the leads 128 of the lead component 120 may be deformed during the manufacturing process, when being set in the tape feeder 90, or when being separated from the taped component in the tape feeder 90. In such a case, as shown in FIG. 5, since the tip positions of the pair of leads 128 of the lead component 120 and the positions of the pair of through holes 122 of the circuit base material 12 cannot be aligned in the vertical direction, there is a risk that the pair of leads 128 cannot be inserted into the pair of through holes 122.

[0021] Therefore, before the leads of the lead component are inserted into the through-holes, an insertion determination is executed to determine whether the leads of the lead component can be inserted into the through-holes. Note that the description of the insertion determination is made using the lead component 140 shown in FIG. 6 instead of the lead component 120. The lead component 140 generally includes a block-shaped component body 142 and eight leads 144 extending from both side surfaces of the component body 142. Four of the eight leads 144 extend from one side surface of the component body 142, and the remaining four of the eight leads 144 extend from the other side surface of the component body 142. And the eight leads 144 extending from both side surfaces of the component body 142 are bent downward at a right angle. For this reason, the tips of the eight leads 144 are arranged in two rows as shown in FIG. 7 from a viewpoint below the lead component 140, and the tips of the four leads 144 in each row are arranged at equal intervals. For this reason, the eight through-holes 146 into which the eight leads 144 of the lead component 140 are inserted are formed in two rows in the circuit base material 12 as shown in FIG. 8, and the four through-holes 146 in each row are arranged at equal intervals. Also, the through-holes 146 are round holes with a circular cross-sectional shape, and the inner diameter of the through-holes 146 is larger than the outer diameter of the leads 144 of the lead component 140 by a predetermined dimension.

[0022] In the following description, the direction in which the tips of one row of leads 144 and one row of through-holes 146 are arranged is described as the Y direction, and the direction in which the tips of one row of leads 144 are arranged and the direction orthogonal to one row of through-holes 146 are described as the X direction. Also, as shown in FIG. 7, the tip positions of the eight leads 144 arranged in two rows indicate the standard values of the lead component 140. That is, FIG. 7 shows the tip positions of the eight leads 144 of the lead component 140 in a state where all of the eight leads 144 are bent as per the standard values and there is no distortion, twist, curvature, warping, etc. Note that the tip position of the lead 144 is the position of the lead that is first inserted when the lead 144 is inserted into the through-hole 146.

[0023] In the production program 110, an allowable range 148 that is larger than the outer diameter dimension of the lead by a predetermined dimension is set at the tip position of the lead located at the standard value position. The allowable range 148 is arranged concentrically with the lead located at the standard value position and has a circular shape with a diameter larger than the lead diameter. For this reason, the clearance between the lead diameter of the lead located at the standard value position and the allowable range 148 is constant in the radial direction of the allowable range 148. That is, the allowable range 148 is the same in the X - direction range and the Y - direction range, and is the common range of the X - direction range and the Y - direction range. Also, the radial dimension of the allowable range 148 is the same as the inner diameter of the through - hole 146. And eight allowable ranges 148 with such an arrangement and dimensions are set in the production program 110.

[0024] Based on the allowable range 148 set in the production program 110 and the imaging data of the lead component 140, an insertion determination is made as to whether the lead 144 can be inserted into the through - hole 146. Specifically, when the lead component 140 held by the suction nozzle 66 is imaged by the parts camera 28, the controller 100 calculates the tip positions of the eight leads 144 of the lead component 140 based on the imaging data. Then, the controller 100 determines whether all of the calculated tip positions of the eight leads 144 are within the allowable range 148.

[0025] At this time, for example, as shown in FIG. 7, when all of the tip positions of the eight calculated leads 144 are within the allowable range 148, the controller 100 determines that the eight leads 144 of the lead component 140 can be inserted into the eight through holes 146. Then, the mounting operation of the lead component 140, for which it has been determined that the eight leads 144 can be inserted into the eight through holes, to the circuit base material 12 is executed according to the above-described procedure. On the other hand, as shown in FIG. 9, when all of the tip positions of the eight calculated leads 144 are not within the allowable range 148, that is, when even the tip position of one of the eight leads 144 is not within the allowable range, the controller 100 determines that the eight leads 144 of the lead component 140 cannot be inserted into the eight through holes 146. Then, the lead component 140, for which it has been determined that the eight leads 144 cannot be inserted into the eight through holes, is discarded into the waste box.

[0026] However, all of the eight through holes 146 into which the eight leads 144 of the lead component 140 are inserted may not be round holes as shown in FIG. 8. For example, there may be a case where eight through holes 150 as shown in FIG. 10 are formed in the circuit base material 12 in order to insert the eight leads 144 of the lead component 140. The eight through holes 150 are formed in two rows in the circuit base material 12, and four through holes 150 are arranged at equal intervals in each row. Also, the direction in which the four through holes 150 are arranged in one row is the Y direction, and the direction orthogonal to the direction in which the four through holes 150 are arranged in one row is the X direction. Then, the four through holes 150a arranged in one of the two rows are circular round holes, and the inner diameter of the through hole 150a is larger than the outer diameter of the lead 144 of the lead component 140 by a predetermined dimension. Also, the four through holes 150b arranged in the other row of the two rows are long holes, and the inner dimension in the X direction is longer than the inner dimension in the Y direction. Note that the inner dimension of the through hole 150b in the Y direction is the same as the inner diameter of the through hole 150a, and the inner dimension of the through hole 150b in the X direction is about three times the inner diameter of the through hole 150a.

[0027] When attempting to insert the eight leads 144 at the tip positions shown in FIG. 9 into such eight through holes 150, as shown in FIG. 11, all eight leads 144 can be inserted into the eight through holes 150. That is, although all eight leads 144 of the lead component 140 cannot be inserted into the eight through holes 146 shown in FIG. 8, all eight leads 144 of the lead component 140 can be inserted into the eight through holes 150 shown in FIG. 10. However, even though all eight leads 144 can be inserted into the eight through holes 150, when the insertion determination is made using the above-described allowable range 148, it is determined that all eight leads 144 cannot be inserted into the eight through holes 150. In view of such a situation, a through hole 150b, that is, an elongated hole-shaped allowable range, is set.

[0028] Specifically, a setting screen 160 for the allowable range shown in FIG. 12 is displayed on the display device 108. On the setting screen 160 for the allowable range, the tip positions of the eight leads 144 of the lead component 140 in a state where all eight leads 144 are bent according to the standard values, that is, the tip positions 162 of the leads according to the standard values, are displayed. Note that information regarding the tip positions 162 of the leads according to the standard values of the lead component 140 is set in the production program 110, and based on the information regarding the tip positions 162 of the leads according to the standard values set in the production program 110, the setting screen 160 for the allowable range is displayed. The tip positions 162 of the leads according to the standard values of the eight leads 144 are arranged in two columns, and four tip positions 162 of the leads according to the standard values in each column are arranged at equal intervals in a state of extending in the Y direction. Among the eight tip positions 162 of the leads according to the standard values arranged in two columns, four tip positions 162 of the leads according to the standard values in one of the same columns are referred to as the tip positions 162a in the first column, and four tip positions 162 of the leads according to the standard values in the other of the same columns among the eight tip positions 162 of the leads according to the standard values arranged in two columns are referred to as the tip positions 162b in the second column.

[0029] Then, on the tolerance range setting screen 160, there are a first-column setting area 164a for setting the tolerance range of the tip position 162a of the first column among the tip positions 162 of the leads according to eight standard values, and a second-column setting area 164b for setting the tolerance range of the tip position 162b of the second column among the tip positions 162 of the leads according to eight standard values. In each of the first-column setting area 164a and the second-column setting area 164b, there are an X-direction input field 166 for inputting the tolerance range in the X direction and a Y-direction input field 168 for inputting the tolerance range in the Y direction. Then, when the operator inputs numerical values into the X-direction input field 166 and the Y-direction input field 168 in each of the first-column setting area 164a and the second-column setting area 164b, the tolerance range of the tip position of the leads of the lead component 140 is set. Note that the numerical values input into the X-direction input field 166 and the Y-direction input field 168 are values corresponding to the inner dimensions of the eight through holes 150 shown in FIG. 10.

[0030] Specifically, for example, when the inner diameter of the four round-hole-shaped through holes 150a into which the four leads 144 of the lead component corresponding to the tip position 162a of the first column are inserted is 3 mm, the operator inputs "3" into each of the X-direction input field 166 and the Y-direction input field 168 in the first-column setting area 164a. That is, the same numerical value is input into the X-direction input field 166 and the Y-direction input field 168. By this input, as shown in FIG. 13, four tolerance ranges 170a arranged concentrically with the four tip positions 162a of the first column are displayed on the tolerance range setting screen 160. The four tolerance ranges 170a are displayed in a round-hole shape with an X-direction dimension of 3 mm and a Y-direction dimension of 3 mm. That is, the four tolerance ranges 170a are displayed in a shape corresponding to the through holes 150a.

[0031] For example, when the inner dimension in the X direction of the four long-hole-shaped through-holes 150b into which the four leads 144 of the lead component corresponding to the tip position 162b of the second column are inserted is 10 mm, "10" is input into the input field 166 in the X direction of the setting area 164b of the second column. Further, when the inner dimension in the Y direction of the four long-hole-shaped through-holes 150b is 3 mm, "3" is input into the input field 168 in the Y direction of the setting area 164b of the second column. That is, different numerical values are input into the input field 166 in the X direction and the input field 168 in the Y direction. As a result, four allowable ranges 170b arranged concentrically with the four tip positions 162b of the second column are displayed on the allowable range setting screen 160. The four allowable ranges 170b are displayed in a shape corresponding to a long hole with an X dimension of 10 mm and a Y dimension of 3 mm. That is, the four allowable ranges 170b are displayed in a shape corresponding to the through-holes 150b. After the eight allowable ranges 170 are displayed on the allowable range setting screen 160, when the OK button 176 is operated, the numerical values input into the input fields 166 in the X direction and the input fields 168 in the Y direction of the setting area 164a of the first column and the setting area 164b of the second column are set in the production program 110 as the allowable range of the lead component 140.

[0032] In this way, on the allowable range setting screen 160, by the operator individually inputting the value in the X direction and the value in the Y direction corresponding to the inner dimension of the through-hole 150, an allowable range corresponding to the long-hole shape can be set. That is, on the allowable range setting screen 160, by the operator individually inputting the range in the X direction and the range in the Y direction of the allowable range, an allowable range corresponding to the long-hole shape can be set. As a result, it becomes possible to appropriately execute the determination as to whether the eight leads 144 of the lead component 140 can be inserted into the eight through-holes 150 including the long holes as shown in FIG. 10.

[0033] Also, on the tolerance setting screen 160, tolerances 170a for the tip positions 162a of each of the four leads in the first column are set according to the standard values, and tolerances 170b for the tip positions 162b of each of the four leads in the second column are set according to the standard values. This makes it possible to reduce the work of numerical input by the operator. Furthermore, the amount of data to be set can also be reduced. That is, for example, when the operator sets tolerances for each of the eight tip positions including the tip position 162a in the first column and the tip position 162b in the second column, it is necessary to individually input the tolerance in the X direction and the tolerance in the Y direction according to each of the eight tip positions. That is, the tolerance input needs to be performed eight times. On the other hand, on the tolerance setting screen 160, the operator can input the tolerance in the X direction and the tolerance in the Y direction for the tip positions 162a of each of the four leads in the first column together, and input the tolerance in the X direction and the tolerance in the Y direction for the four tip positions 162b in the second column together. That is, on the tolerance setting screen 160, the input of the tolerance in the X direction and the tolerance in the Y direction only needs to be performed twice. This makes it possible to reduce the work of numerical input by the operator and also reduce the amount of data to be set.

[0034] Note that the display device 108 is an example of a display device. The lead component 140 is an example of a lead component. The lead 144 is an example of a terminal. The through hole 150 is an example of an insertion hole. The tolerance setting screen 160 is an example of a setting screen.

[0035] Furthermore, the present invention is not limited to the above-described embodiments, and can be implemented in various forms with various changes and improvements based on the knowledge of those skilled in the art. For example, in the above embodiment, the operator inputs the range in the X direction and the range in the Y direction within the allowable range together according to the tip position 162a of the leads in the first column conforming to the standard value, and inputs the range in the X direction and the range in the Y direction within the allowable range together according to the tip position 162b of the leads in the second column. On the other hand, the operator may individually input the range in the X direction and the range in the Y direction within the allowable range according to each of the tip positions of the eight leads conforming to the standard values. Specifically, a tolerance setting screen 180 shown in FIG. 14 is displayed on the display device 108. On the tolerance setting screen 180, the tip positions 182 of the eight leads conforming to the standard values are displayed in the same arrangement as the tip positions 162 of the eight leads conforming to the standard values on the tolerance setting screen 160. Further, on the tolerance setting screen 180, tolerance setting areas 184a to 184h for setting the tolerance for each of the tip positions 182a to 184h of the eight leads conforming to the standard values are displayed, and in each of the tolerance setting areas 184a to 184h, an X-direction input field 186 for inputting the tolerance range in the X direction and a Y-direction input field 188 for inputting the tolerance range in the Y direction are displayed. Then, when the operator inputs numerical values into the X-direction input fields 186 and the Y-direction input fields 188 in each of the tolerance setting areas 184a to 184h, the tolerance range is set for each of the eight leads 144. In this way, by setting the tolerance range for each of the eight leads 144, it is possible to appropriately set the tolerance range corresponding to through-holes of various shapes.

[0036] Also, in the above embodiment, the tolerance range in the X direction and the tolerance range in the Y direction are input as individual tolerance ranges, but the tolerance range in the X direction and the tolerance range in the Y direction may be input as a common tolerance range. That is, for example, when "3" is input as the common tolerance range for the tolerance range in the X direction and the tolerance range in the Y direction, a circular tolerance range with a diameter of 3 mm is set. Thereby, the number of inputs can be reduced.

[0037] In the above embodiment, the operator inputs the allowable range, but the allowable range may also be automatically input. That is, for example, the circuit base material 12 is imaged by the mark camera 26 or the like, and the controller 100 calculates the dimensions in the X direction and the Y direction of the through hole based on the imaging data. Then, the controller 100 may set the allowable range by automatically inputting the allowable range using the dimensions in the X direction and the Y direction of the through hole.

[0038] In the above embodiment, the allowable range in the X direction and the allowable range in the Y direction are input as the allowable range. That is, the allowable ranges in two directions orthogonal to each other are input. However, it is not limited to two directions orthogonal to each other, and the allowable ranges in two directions that intersect each other and are not orthogonal to each other may be set as long as they intersect each other.

[0039] In the above embodiment, the eight leads 144 of the lead component 140 are arranged in two rows, and the allowable range of the tip positions of the four leads arranged in one row out of the eight leads 144 arranged in those two rows, and the allowable range of the tip positions of the four leads arranged in a row different from that row are set individually. On the other hand, for example, when a plurality of leads are arranged in three rows, the allowable range of the tip positions of the leads arranged in one row, the allowable range of the tip positions of the leads arranged in a row different from that row, and the allowable range of the tip positions of the leads arranged in a row different from those two rows may be set individually. Also, when a plurality of leads are arranged in three rows, for example, the allowable range of the tip positions of the leads arranged in one row and the allowable range of the tip positions of the leads arranged in two rows different from that row may be set individually. Further, for example, in a lead component in which a plurality of leads extend from each of the four side surfaces of a rectangular component body such as a QFP (Quad Flat Package), a plurality of leads are arranged in four rows along the four sides of the component body. In such a case, the allowable range of the tip position of each of the four rows of leads may be set individually, or the allowable range of the tip positions of the two rows of leads extending in the same direction and the allowable range of the tip positions of the two rows of leads orthogonal to the extending direction of those two rows may be set as each set. That is, as long as the allowable range of the tip positions of all the plurality of leads of the lead component can be set, the allowable range of the tip positions of the leads may be set for each row, or the allowable range of the tip positions of the leads in a plurality of rows may be set collectively.

[0040] In the above embodiment, the allowable range of the tip positions of the leads arranged in one row is set as the allowable range of the tip positions of one set of leads, but the allowable range of the tip positions of adjacent leads may be set as the allowable range of the tip positions of one set of leads. Also, the allowable range of the tip positions of the leads within a predetermined range may be set as the allowable range of the tip positions of one set of leads.

[0041] Also, on the tolerance setting screen 160, an X-direction input field 166 and a Y-direction input field 168 are simultaneously displayed in each of the setting area 164a in the first column and the setting area 164b in the second column. However, the X-direction input field 166 and the Y-direction input field 168 may be displayed at different timings. That is, for example, after the X-direction input field 166 is displayed and an arbitrary value is input to the X-direction input field 166, the X-direction input field 116 may be made non-displayed, and then the Y-direction input field 168 may be displayed on the setting screen 150.

[0042] In the above embodiment, a through hole is adopted as the insertion hole into which the lead is inserted. However, as long as it is a hole having an inner wall surface such as a bottomed hole or a recess, various insertion holes can be adopted.

[0043] Needless to say, various types of standards such as industrial standards, JIS standards, design standards, user standards, and manufacturer standards are applied to the standard values at the tip positions of the leads of the lead components in the embodiment.
