  The present invention relates to a component suction position setting gauge that can be used to set a component suction position when a component supplied to a component mounting apparatus is picked up by a component suction nozzle from a component supply tape in which the component is stored. And a component suction position setting method.

  An example of a component mounting apparatus is shown in FIG. In the figure, a component mounting apparatus 50 includes a component supply unit 51 that supplies components to be mounted, a mounting head 53 that takes out components from the component supply unit 51 and mounts them on a circuit board 52, and conveys the mounting head 53 to a predetermined position. A robot 54, a substrate holding unit 56 that carries in and holds the circuit board 52, a control unit 57 that controls the overall operation, and an input terminal 58 that inputs necessary control data by an operator. A component supply device 30 capable of sequentially supplying the components 10 is attached to the component supply unit 51.

  In the technical field of component mounting, in order to take out the supplied component 10 and mount it on the circuit board 52, there is a component suction nozzle (hereinafter referred to as “nozzle”) 1 that sucks and holds the component using negative pressure. Widely used. In the example shown in FIG. 4, four nozzles 1 are mounted on the mounting head 53, and each nozzle 1 performs from the removal of the component 10 to mounting.

  5A to 5C show an example of the nozzle 1. In the figure, the nozzle 1 has a connecting portion 2 for connecting to a mounting head 53 located at the upper side in the longitudinal direction, and an adsorbing portion 3 for adsorbing components under the same. Between the upper connecting part 2 and the lower suction part 3, two flanges 4 into which an attaching / detaching tool (not shown) is inserted when attaching / detaching the nozzle 1 to / from the mounting head 53 are provided. Depending on the shape, size, etc. of the component 10 to be sucked, the nozzle 1 mounted on the mounting head 53 can be replaced using the mounting / demounting tool. A component suction surface 6 orthogonal to the longitudinal axis (center axis) 5 of the nozzle 1 is formed at the lower end portion of the suction portion 3, and this component suction surface 6 contacts the upper end surface of the component 10 during suction.

  FIG. 5B shows the suction part 3 in an enlarged manner. As shown in the drawing, in the suction portion 3, a lower cylindrical portion 13 extends from the upper cylindrical portion 12, and an inverted truncated pyramid portion 14 extends further downward from the lower cylindrical portion 13 to form a rectangular component suction surface 6 at the tip. Connected to. A suction hole 7 shown in the bottom view of FIG. 5C is opened in the component suction surface 6 located at the tip of the suction portion 3. Between the suction hole 7 and the upper opening 9 (see FIG. 5A) formed in the upper end surface 8 of the connecting portion 2, an air passage 15 (partially indicated by a broken line) formed in the nozzle 1 is provided. Are fluidly connected to each other. At the time of component suction, the nozzle 1 is brought into contact with the component 10 so that the center of the suction hole 7 coincides with the target component suction position of the component 10, and the component mounted on the component suction surface 6 using the negative pressure supplied from the mounting head 53. 10 is adsorbed. At the time of component mounting, the component 10 is separated from the component suction surface 6 and mounted using the positive pressure supplied from the mounting head 53.

  Next, FIG. 6 shows an example of the component supply tape 20 that continuously supplies components to the component mounting apparatus 50. In the figure, the component supply tape 20 includes a base tape 21 that houses the component 10 and a cover tape 22 that covers the base tape 21. When supplying components to the component mounting apparatus 50, the component supply tape 20 has feed holes 24 that are used to sequentially convey and drive the component supply tape 20 toward the component mounting apparatus 50. It is provided at intervals.

  Similarly, the base tape 21 is provided with concave component storage portions 23 formed by embossing at equal intervals in the longitudinal direction. The component 10 is stored in the component storage portion 23 and is covered and protected by a cover tape 22 attached to the base tape 21. The cover tape 22 prevents the component 10 from dropping from the component storage unit 23 or being displaced in the component storage unit 23 until it is peeled off from the base tape 21 later. The component supply tape 20 configured as described above is wound around a reel 25 and loaded into a component supply device described later.

  When the size of the component 10 is very small, the base tape 21 does not have to be provided with a component storage portion 23 by an embossed portion formed by embossing, and the paper base tape 21 is simply punched into the hollow punched portion. There is also a punching-type component supply tape 20 that houses the component 10 and protects it from the front and back with a cover tape 22.

  FIG. 7 shows an example of a component supply device 30 that attaches the above-described reel 25 and sequentially supplies components to the component mounting device 50. In the figure, a component supply device 30 includes a main body portion 31 that can be attached to a component supply portion 51 (see FIG. 4) of a component mounting device 50, and a reel attachment portion that attaches a reel 25 around which the component supply tape 20 is wound. 32, a tape transport drive unit 33 that pulls and transports the component supply tape 20 from the reel 25, and a cover tape recovery unit 34 that recovers the cover tape 22. A support pin 35 that holds the reel 25 rotatably is fixed to the reel mounting portion 32.

  FIG. 8 shows an outline of a mechanism for transporting the component supply tape 20 drawn from the reel 25 inside the component supply device 30. After the component supply tape 20 is pulled out from the reel 25, the component supply tape 20 is conveyed by driving the drive wheels 36 of the tape conveyance drive unit toward the component extraction position 37 located on the right side on the conveyance path 38. In the component supply apparatus 30 shown in FIG. 8, the drive wheel 36 of the type driven by the rotation of the motor 41 through the worm gear 49 is used. In addition, a mechanical system using a ratchet or an air cylinder is used. There are various drive systems such as fluid system. The teeth provided at equal intervals on the outer periphery of the drive wheel 36 are engaged with the feed holes 24 of the component supply tape 20 described above, and the component supply tape 20 is intermittently transported and driven by a predetermined distance. Yes.

  The operation of the component supply apparatus 30 configured as described above is as follows. 7 and 8, the component supply tape 20 is pulled out from the reel 25 that is rotatably attached to the support pin 35, and the feed hole 24 of the component supply tape 20 is connected to the teeth of the drive wheel 36 in the tape conveyance drive unit 33. It is engaged. The component supply tape 20 is conveyed toward the component mounting apparatus 50 by intermittent rotation driving of the drive wheel 36 by a driving source such as a motor 41 synchronized with the operation of the component mounting apparatus 50. A shutter 39 (FIG. 8) for protecting the component 10 is provided at the component removal position 37, and the nozzle 1 (not shown) of the component mounting apparatus descends from above the component removal position 37 in synchronization with the opening of the shutter 39. Then, the component 10 is sucked out from the component supply tape 20. The cover tape 22 that has previously protected the component 10 is peeled off in accordance with the movement of the shutter 39 immediately before the component take-out position 32, and is wound and collected by a reel of a cover tape collecting unit 34 that is intermittently driven to rotate. . In addition, the base tape 21 that has finished conveying the components is continuously conveyed by the drive wheels 36 and collected in a collection box (not shown) below.

  9A to 9C show various shapes of components 10 (10a to 10c) housed in the component supply tape 20, and target component suction positions 11 (11a to 11a) when the components 10 are sucked by the nozzle 1. 11c). Here, the component suction position 11 means a surface position on the component 10 that coincides with the center position of the suction hole 7 of the nozzle 1 shown in FIG. 5C when the component 10 is sucked by the nozzle 1. As the shape of the component 10, in addition to the substantially square or rectangular component 10a as shown in FIG. 9A, non-target variants such as connectors and shields as shown in FIGS. 9B and 9C are used. Parts 10b and 10c are included. The component shapes shown in the figures are merely examples. In order to stably supply these variously shaped parts 10, it is required to correctly set the target part suction position 11 according to the part shape so that the part 10 does not tilt or fall off during part suction. .

  In the case of a substantially square or rectangular component 10a as shown in FIG. 9A, the center position of the component 10 that is normally the intersection of diagonal lines can be set as the component suction position 11a except when the weight is extremely unevenly distributed. It is. On the other hand, in the case of irregularly shaped parts 10b and 10c as shown in FIGS. 9B and 9C, the operator appropriately sets the appropriate part suction positions 11b and 11c according to the shape. For example, in the case of FIG. 9B, the target component suction position 11b is set at the approximate center of gravity position that is offset from the center position of the component storage portion 23 in consideration of the difference between the left and right shapes of the component 10b. On the other hand, in the case of FIG. 9C, the component 10 does not physically exist in the vicinity of the center of gravity, and the component cannot be adsorbed at this position. The component suction position 11c is set above.

  When the target position 11 is determined, the operator uses the input terminal 58 (see FIG. 4) provided in the component mounting apparatus 50 to input the position information. In this case, for the substantially square or rectangular component 10a as shown in FIG. 9A, the suction position 11a is the center of the component 10a, so that the control unit 57 of the component mounting apparatus 50 automatically picks up the suction position. Set. On the other hand, in the case of irregularly shaped parts 10b and 10c as shown in FIGS. 9B and 9C, the operator moves from the center position of the part to the longitudinal direction of the part supply tape 20 (up and down direction in the figure), and Expecting an offset amount in the width direction (same as the left and right direction) orthogonal to this, the component suction positions 11b and 11c are set by inputting this offset amount. That is, the setting of the component suction position 11 generally means the setting of the offset amount from the center position of the component 10. Once the component suction position 11 is set, the operator activates the component mounting apparatus 50, observes the component suction status, and if it can be confirmed that there is no problem, the operator starts continuous operation under the same conditions. If the component suction is unstable, the operator re-enters the offset amount and repeats the same procedure to find an appropriate component suction position (see, for example, Patent Document 1).

  In the example shown in FIGS. 9A and 9B, the feed holes 24 are provided on both sides in the width direction of the component supply tape 20, whereas in the example shown in FIG. 9C, the feed hole 24 is on one side. Only provided. This is defined by the JIS standard (C 0808-3), and the tape width W (shown in Fig. 9 (a)) is only on one side up to 24mm, and on the wider side (32mm or more) on both sides 24 is provided. At this time, from the feed hole 24 located on the left side with respect to the conveying direction indicated by the arrow 27 to the center position of the component 10 (that is, the center position in the width direction of the component storage portion 23 provided in the component supply tape 20) The distance is defined based on a slightly different standard when the feed hole 24 is on both sides and when it is only on one side.

  For example, when the tape width is 24 mm (feed hole only on one side), the distance to the center position is 11.5 mm from the feed hole 24, while when the tape width is 32 mm (feed hole on both sides), the distance is 28.4 It is set to mm. From this calculation, the central position of the component 10 in the tape width direction is closer to the left side feed hole 24 by 1.3 mm when the feed hole 24 is provided on both sides and the feed hole 24 is provided only on one side. . This means that when the feed hole 24 on the left side of the drawing is used as a positioning reference, a deviation occurs between the feed hole 24 on both sides and the one on only one side. The specifications of the feed holes 24 are stipulated in the JIS standard such that the hole diameter is 1.5 mm, the pitch Po between the feed holes is 4 mm, and the feed hole 27 on the right side with respect to the conveying direction 27 is a long hole. ing.

Here, the wide component supply tapes 20a and 20b shown in FIGS. 9A and 9B and the narrow component supply tape 20c shown in FIG. 9C have different scales (FIG. 9C). ) Is drawn). Actually, both of the dimensions of the feed holes 24 are 1.5 mm, and the pitch Po of the feed holes 24 is also 4 mm.

  There has been a problem in setting the component suction position by the operator described above. That is, conventionally, an operator generally receives the component supply tape 20, and sets the target component suction position 11 at the site after looking at the specifications of the component supply tape 20 and the shape of the component 10. In particular, in the case of a processing manufacturer or the like who performs component mounting under commission, there are few opportunities to give detailed information on the component 10, and therefore the component suction position 11 currently depends on the setting according to the operator's amount. In such a case, the operator usually applies a steel measure or the like at hand to the component supply tape 20, and considers the shape of the component 10 and estimates the offset amount from the center position of the component 10 based on the reading of the steel measure. Yes.

  Therefore, the component suction position 11 set by such a method can include a large error. For example, when a steel measure is applied, the direction becomes unstable and the right angle cannot be determined correctly with respect to the component supply tape 20. When applied obliquely, a deviation from the center position of the component 10 with respect to the transport direction 27 may occur. In this case, the error increases as the component supply tape 20 becomes wider. Furthermore, since it is difficult to correctly apply the steel measure to the center position also in the width direction of the part, variations easily occur in the left-right direction. As described above, when the target component suction position 11 is set by the conventional method, stable component supply cannot be performed at the time of trial when the component mounting apparatus 50 is operated, and the trial operation is performed by resetting the offset amount. Is repeated, and wasteful labor and time are required, which causes a reduction in equipment operation rate. Conventionally, it is not uncommon to require half a day and extremely one day just by correctly setting the component suction position 11.

  The present invention solves the above-described problems in the prior art, and can be easily used in the field when an operator sets a target component suction position. An object of the present invention is to provide a component suction position setting gauge and a component suction position setting method that can be set.

  The present invention provides a positioning means that can reliably perform positioning in the longitudinal direction of the component supply tape and the width direction orthogonal thereto with reference to the component supply tape itself or a feed hole provided in the component supply tape, By providing a component suction position setting gauge with a scale that can easily and accurately read the offset amount in both directions from the center position of the component, it solves the problems of the conventional technology, more specifically Includes the following:

  That is, according to one aspect of the present invention, a component suction position is set when a component transported to a component supply device and supplied to a component mounting device is taken out from a component supply tape containing the component by using a component suction nozzle. A main body portion made of a transparent substantially rectangular flat plate member, a position specifying scale formed in the main body portion so as to be visible, a longitudinal axis of a component supply tape, and a right angle to the axis Positioning means formed on the main body portion for positioning the main body portion along an axis in the width direction of the component supply tape, and applying the main body portion to the component supply tape using the positioning means. Further, the present invention relates to a gauge that determines a component suction position of a component stored in the component supply tape using the scale.

  The positioning means uses at least two of the feed holes provided continuously along the longitudinal direction of the component supply tape to convey and drive the component supply tape, or at least one of the feed holes and the component The said main-body part can be positioned using the one end side extended in the longitudinal direction of a supply tape. More specifically, the positioning means is provided in the main body portion in alignment with a bent portion bent in an L shape from the main body portion along one end in the width direction of the component supply tape, and a feed hole of the component supply tape. The pin, the hole, the mark, the slit portion, the claw portion, or any combination thereof can be used.

  The positioning means may include positioning means for applying to the component supply tape provided with the feed holes on both sides in the width direction, and positioning means for applying to the component supply tape provided with the feed holes only on one side in the width direction. Good. In this case, when the conveying direction of the component supply tape is the same, the positioning means rotates the gauge 180 degrees on the plane of the main body portion, so that the feed hole and the component supply tape provided on both sides in the width direction have a width. It can be selectively applied to any one of the component supply tapes provided only on one side of the direction.

  The scale provided on the gauge is a grid-like scale based on the longitudinal axis and the width axis printed on the film printed on the main body part or attached to the main body part. can do. The grid-like scale includes a plurality of vertical axis directions along the longitudinal direction of the component supply tape and a horizontal axis direction along the width direction of the component supply tape, which are orthogonal to each other every 2 mm pitch or every 0.1 inch pitch. In order to improve visibility, it is preferable to form the straight line.

  In this case, among the straight lines in the horizontal axis direction of the grid-like scale, a straight line that coincides with the center position of the component, a straight line that is separated from the straight line by 10 mm pitch or 0.5 inch pitch, and the grid-like scale Of the straight lines in the vertical axis direction, at least one of the straight lines that coincide with the center position in the width direction of the components stored in the component supply tape of various dimensions in a state of being positioned by the positioning means, Can be displayed thicker than the straight line. It is preferable that the thickly displayed straight line and the other straight lines are colored differently from each other in order to improve visibility by the operator. Specifically, one of the thickly displayed straight line and the other straight line can be colored red, and the other can be colored yellow. The bold line in the vertical axis direction of the grid-like scale may be displayed with an arrow indicating the conveyance direction of the component supply tape.

  The gauge for setting the component suction position described above can be made by either injection molding or plate molding of a synthetic resin material. The synthetic resin material can be polycarbonate. Further, it is convenient to make the gauge approximately the size of a business card.

  Another aspect of the present invention is a method of setting a component suction position when a component stored in a component supply tape is taken out by using a component suction nozzle in component mounting, for transporting and driving the component supply tape. At least two of the feed holes provided continuously along the longitudinal direction of the component supply tape, or at least one of the feed holes and one end side extending in the longitudinal direction of the component supply tape. And using the feed hole to align the horizontal axis with the center position of the longitudinal part. The orthogonal coordinates of the vertical axis along the longitudinal direction and the horizontal axis orthogonal to the longitudinal direction are obtained. Further, the present invention relates to a method for determining a component suction position using a grid-like scale based on the orthogonal coordinates.

  By implementing the present invention, it becomes possible for the operator to set the component suction position in a short time and with high accuracy in accordance with the specifications of the component supply tape and the specifications of the component at the component mounting processing site. It can contribute to improvement of operating rate and stable quality of component mounting.

  A component suction position setting gauge (hereinafter also simply referred to as “gauge”) according to a first embodiment of the present invention will be described with reference to the drawings. 1A and 1B show a gauge according to the present embodiment. FIG. 1A is a plan view and FIG. 1B is a side view. In both figures, the gauge 60 is a substantially rectangular plate-like main body 61, a plurality of pins 62 (62 a or 62 b) serving as positioning means protruding from the main body 61, and components formed on the surface of the main body 61. The scale 63 is used when the suction position 11 is set.

  Of these, the main body 61 is preferably made by, for example, injection molding using a transparent synthetic resin material such as polycarbonate. The scale 63 is formed by printing directly on the surface of the main body 61 or by attaching a film on which the scale 63 is printed to the main body 61.

  In FIG. 1A, the plurality of pins 62a provided at the right end are pitches that can be engaged with the feed holes 24 of the component supply tape 20 shown in FIG. 6 (in the JIS standard, (4 × n) mm. ) In a straight line. In the example shown in the figure, four pins 62 a are provided, and the two pins 62 a in the central portion thereof are formed in two continuous feed holes 24 sandwiching the center position of the component 10 in the longitudinal direction of the component supply tape 20. Engageable. Further, the two pins 62a near the upper and lower end portions are disposed so as to be able to engage with the feed holes 24 located at a distance of 5 pitches from each of the two central portions.

  The position and number of these pins 62a can be arbitrarily set. However, when the gauge 60 is applied to the component supply tape 20, the gauge 60 is accurately set in the longitudinal direction of the component supply tape 20 and in the width direction perpendicular thereto. It is preferable that at least a pair of pins 62a is provided at positions as far as possible in the longitudinal direction so that positioning is possible. Accordingly, the two pins 62a in the central portion are not necessarily required for positioning, but it is convenient to have them when aligning the gauge 60 with the longitudinal center position of the component 10 described above.

  Next, the scale 63 is basically composed of straight lines orthogonal to the grid, based on the orthogonal coordinates of the vertical axis along the longitudinal direction of the component supply tape 20 and the horizontal axis along the width direction perpendicular thereto. Has been. In the illustrated example, straight lines are drawn at 2 mm pitch intervals in both the vertical and horizontal directions, and on the horizontal axis, a thick line is drawn every 10 mm span with reference to the center position of the component 10 so that the length can be read at a glance. . On the vertical axis, when the plurality of pins 62a are engaged with the feed holes 24 of the component supply tape 20 as described above, each of the component supply tapes 20 having a width of 32 mm, 44 mm, 56 mm, and 72 mm (according to JIS standards) is provided. The lines corresponding to the center position in the width direction of the housed component 10 are indicated by bold lines. Further, these vertical thick lines are arrows, which clearly indicate the conveying direction of the component supply tape 20.

  For example, it is assumed that the gauge 60 is applied to the component supply tape 20a indicated by the two-dot chain line in FIG. The tape width of this component supply tape 20a is 72 mm. The gauge 60 is applied to the component supply tape 20a by engaging a plurality of pins 62a with the corresponding feed holes 24. At this time, the two pins 62 a at the center are engaged with the two feed holes 24 arranged with the center position in the vertical direction of the component 10 interposed therebetween. Since the pitch of the feed holes 24 is 4 mm, the center line of the horizontal axis is far from the center position of the component 10 when the gauge 60 is engaged with one wrong feed hole 24 at the center position. Therefore, the operator can easily notice an error in the engagement position.

  With the pin 62a of the gauge 60 engaged with the feed hole 24 of the component supply tape 20a and the gauge 60 applied to the component supply tape 20a, the vertical and horizontal axis directions of the scale 63 printed on the gauge 60 are respectively It is positioned in the longitudinal direction of the component supply tape 20a and the width direction orthogonal thereto. From the intersection of the thick line at the center position of the horizontal axis and the thick line of the vertical axis labeled “72” (when the tape width is 72 mm), the operator can store the component 10 stored in the component supply tape 20. Center position C1 can be recognized.

  Based on this central position, the shape of the component 10 that can be seen through from the transparent gauge 60 is taken into consideration, and the operator sets target adsorption positions 11a to 11c as shown in FIGS. 9A to 9C, for example. The amount of offset from the center position C is visually read from the scale 63. In order to facilitate reading by the operator at this time, various measures are incorporated in the gauge 60 of the present embodiment.

  The first is that vertical and horizontal grid-like straight lines have a pitch of 2 mm. This facilitates reading, and ensures the accuracy necessary for setting the target suction position. For example, if these straight lines are drawn every 1 mm pitch, the scale may be too close and it may be difficult for the operator to read. In particular, there are many cases where it is not always possible to ensure sufficient illumination at the manufacturing site, and reading can be even more difficult. When the pitch is 2 mm, it can be read visually with an accuracy of 1/4 (that is, 0.25 mm) or 1/5 (that is, 0.20 mm) of the pitch. And with respect to the setting of the component suction position 11, the use with this accuracy is sufficiently possible. When the pitch is 3 mm or more, the reading accuracy is lowered. For the same reason, it is preferable that the pitch is 0.1 inch (about 2.54 mm) in the case of inch standard, and the thick line on the horizontal axis is preferably set every 0.5 inch.

  Next, each straight line of the scale 63 is such that the fine line is colored yellow and the thick line is colored red, thereby making it easy to read the scale 63 with respect to the background. The color used for the component supply tape 20 is not particularly specified, but normally white or black is used. By using the scale 63 with the color arrangement, the scale 63 can be easily distinguished even when applied to the component supply tape 20, and the distinction between the thin line and the thick line is also facilitated. In addition, as for the above-mentioned color scheme, one of a thin line and a thick line should just be red, and the other should be yellow. Alternatively, other colors that facilitate discrimination with respect to the background may be combined.

  Furthermore, as described above, the conveying direction of the component supply tape 20 is indicated by an arrow on the bold line on the vertical axis. As a result, when the gauge 60 is applied to the component supply tape 20, the operator mistakenly positions the gauge 60 in the reverse direction.

  As described above, when the feed holes 24 are provided on both sides in the width direction of the component supply tape 20 or only on one side, the distance from the feed hole 24 to the center position in the width direction of the component 10 is about 1.3 mm. There is a gap. Therefore, the positioning pin 62a described so far cannot be used for the narrow component supply tape 20 in which the feed hole 24 is provided only on one side. In the present embodiment, in response to this, a plurality of positioning pins 62b that can be used for the narrow component supply tape 20 in which the feed holes 24 are provided only on one side are separately provided on the right side of the drawing.

  In FIG. 1A, the arrangement method of the plurality of pins 62b is the same as the pin 62a described above, and is arranged so as to be engageable with the feed holes 24 of the narrow component supply tape 20. . For example, it is assumed that the gauge 60 is applied to a narrow component supply tape 20b indicated by a two-dot chain line in the figure. Actually, the direction of the gauge 60 is rotated 180 degrees on the drawing so that the conveying direction is upward, so that the direction is the same as described above. However, for convenience of drawing, the component supply tape 20b is conveyed at this time. The direction is displayed downward. For this reason, the arrow which shows the conveyance direction shown on the thick line of a vertical axis | shaft is also displayed facing the downward direction. If the conveyance direction of the component supply tape 20 is in the same state, a wide component with feed holes 24 provided on both sides is obtained by rotating one gauge 60 180 degrees on the plan view shown in FIG. It is possible to selectively use either a supply tape or a narrow component supply tape provided with a feed hole 24 only on one side.

  The procedure for setting the component suction position 11 in the case of the component supply tape 20b in which the feed hole 24 is provided only on one side is the same as that described above. The pin 62b is engaged with the feed hole 24 of the component supply tape 20b. In the example shown in the drawing, the width of the component supply tape 20b is 24 mm, so that the center position C2 of the component 10 can be easily determined by the intersection of the bold arrow on the vertical axis with “24” and the center position of the component on the horizontal axis. Can be identified. After that, the component suction position 11 can be set by determining the offset amount using the scale 63 according to the shape of the component 10.

  In addition, in the gauge 60 concerning this Embodiment, the other countermeasures which considered the user's convenience in addition to the visibility countermeasure of the scale 63 mentioned above are also folded. For example, the entire size of the gauge 60 is approximately the size of a business card, which facilitates storage and handling for the operator. The size of the business card here refers to the size that can be easily stored in a pocket of business clothes or a business card holder. More specifically, the size is 55mm x 90mm as a standard, plus or minus 10mm for each length and width. The size including the allowable width of. Further, as shown in FIG. 1A, a metric scale and an inch scale are provided on both sides in the longitudinal direction, respectively, for convenience in use for various applications. The material is flexible as the above-mentioned polycarbonate, and the plate thickness is reduced to enable easy handling.

  In this embodiment, one gauge 60 can be used for two types of component supply tapes 20 of one side and one on both sides. Of course, it is also possible. In addition, in the example shown in FIG. 1A, the tape width is limited to 12 mm, 16 mm, 24 mm in the case of one-side feed holes, and 32 mm, 44 mm, 56 mm, 72 mm in the case of double-side feed holes. This is the same up to the setting according to the JIS standard, and the same can be applied to the component supply tape 20 having other width dimensions as required. The same applies to the component supply tape having a width dimension based on inches.

  In the example shown in FIG. 1A, the center position of the horizontal axis of the component 10 is positioned between the two pins 62 at the center of the plurality of pins 62 (62a or 62b). Even if the component feed pitch (P shown in FIG. 9A) corresponding to the length of one component 10 in the vertical direction is an odd multiple of the pitch of feed holes 24 (Po), it is an even multiple. However, it is because the center position of the component is stipulated in the JIS standard so that it is always in the middle of the two pins 62 in the center portion. However, the present invention can be applied even when the center position of the horizontal axis of the component 10 matches the position of the pin 62 outside the JIS standard. In this case, the pin 62 in the central part is made into one and it arrange | positions so that it may correspond to the center position of the said component 10, and other pins 62 are separated from the pin 62 in the said central part by (4xn) mm. What is necessary is just to arrange | position so that it may become.

  FIG. 2 shows another aspect of the component suction position setting gauge according to the present embodiment. In the illustrated gauge 60a, auxiliary scales 64 capable of reading the width dimension of the component supply tape 20 are provided at the upper and lower ends of the figure in place of the previous metric scale and inch scale. If the operator is accustomed to component mounting, the width dimension can be determined immediately by just looking at the component supply tape 20, but in some cases the width dimension may not be known. In such a case, by using the auxiliary scale 64 as shown in FIG. 2, when the feed hole 24 is engaged with the corresponding pin 62a or 62b, the feed hole 24 is on the opposite side in the width direction. By reading the position of the end side of the component supply tape 20 from the auxiliary scale 64, the width dimension of the component supply tape 20 can be confirmed without error. And the center position of the component 10 can be known using the thick vertical line of the scale 63 displaying the read width dimension. The other contents of the gauge 60a are the same as those described so far.

  Next, a component suction position setting gauge according to a second embodiment of the present invention will be described with reference to the drawings. In the present embodiment, various gauges including positioning means that can replace the positioning pins 62 shown in the previous embodiment are disclosed. Therefore, the elements other than the positioning means are the same as those described in the previous embodiment.

  In FIG. 3A, positioning holes 65 (65a, 65b) are provided in place of the positioning pins 62. The operator can determine the component suction position 11 (not shown) by aligning the at least two holes 65 with the feed hole 24 of the component supply tape 20. In some cases, a fixing jig made of a plurality of bar members arranged at the same pitch may be separately provided, and the feed hole 24 and the positioning hole 65 may be simultaneously inserted into the bar member to be positioned and fixed. By adopting such a type of gauge 60, there is no need to make pins 62 as shown in FIG. 1 (a) by injection molding, and it is easy to mold simply by punching a plate-like member, reducing costs. can do.

  Note that a positioning mark may be printed (or pasted) instead of the hole 65, and the mark and the feed hole 24 may be aligned. In FIG. 3A, a positioning hole 65a for a wide component supply tape 20 provided with feed holes 24 on both sides in the width direction, and a positioning hole 65b for a narrow component supply tape 20 provided with feed holes 24 only on one side. Are displayed separately. In the following alternatives, only one of them is displayed and the other is omitted. However, it can be similarly applied to both the wide and narrow component supply tapes 20.

  In the example shown in FIG. 3B, an L-shaped bent portion 66 is provided at the end of the gauge 60. During positioning, the bent portion 66 is pressed against one end side in the width direction of the component supply tape 20 to position the gauge 60 in the longitudinal direction of the component supply tape 20 (and the width direction perpendicular thereto). it can. With respect to the component center position, a slit portion 67 (which may be a hole) is provided and can be aligned with the feed hole 24. In this alternative, processing can be performed by molding a plate-like member, but injection molding may be used. In the case of injection molding, at least one pin 62 (see FIG. 1A) may be provided instead of the slit portion 67 (or hole).

  In the case shown in FIG. 3B, the longitudinal direction of the tape and the width direction perpendicular to the tape are positioned by pressing the L-shaped bent portion 66 against the component supply tape 20, and therefore the slit portion 67. If there is at least one (or hole), alignment with the center position of the component 10 is possible.

  In the example shown in FIG. 3C, a plurality of claw portions 68 bent from the end surface in the width direction of the gauge 60 are provided. Since the claw portion 68 is formed with a pitch and a size that can be fitted into the feed hole 24, the gauge 60 can be easily positioned by engaging both of them. Further, the processing of the plate-like member makes the molding easier than the injection molding. In the example shown in FIG. 3D, a plurality of slit portions 69 are formed at the terminal to enable alignment with the feed hole 24.

  The alternatives shown in FIGS. 3A to 3C and the pin 62 shown in FIG. 1A are collectively referred to as positioning means for positioning the gauge 60 with respect to the component supply tape 20. . The pins 62 and their alternatives can be used alone or in any appropriate combination.

  By using the component suction position setting gauge according to each of the embodiments of the present invention described above, the operator can press the scale measure and set the component suction position with the amount of scale. Improvement and workability can be improved.
