  Hereinafter, an embodiment of an electronic component mounting apparatus will be described based on the drawings. FIG. 1 is a plan view of the electronic component mounting apparatus 1. The electronic component mounting apparatus 1 is divided into a total of four blocks (reference numerals are basically only LU blocks): two blocks LU and LD on the left and right and two blocks RU and RD on the right. Each block is provided with a number of known tape feeders, a component supply area 13, a mounting head 6, a mounting head fixed to the mounting head body 11 that moves on a rail 18 for left and right movement constituted by a linear motor, In addition, in order to correct the position of the suction nozzle 8 shown in FIG. 2 of each mounting head 6 when mounted on the substrate, a component recognition camera 19 that captures the suction holding state of the components of the suction nozzle 8 is provided. The left and right blocks are each provided with a vertical movement rail 16 constituted by a linear motor in which a mounting head body 11 common to the upper and lower blocks moves up and down. Further, in the center, there are four chutes 5 for transporting the substrate P, the upper two chutes 5c and 5d are for the upper block substrate transport line U, and the lower two chutes 5a and 5b are for the lower block. The substrate transport line D is configured. The substrate P is distributed by the delivery unit 17 and carried into the substrate transport line U or D.

  FIG. 2 shows the lower part of the mounting head 6 in the present embodiment, and mainly shows the suction nozzle portion 7 provided at the tip thereof. A plurality of suction nozzles 7 are provided on the mounting head 6 (12 in this embodiment), and FIG. 2 shows 7α and 7β arranged diagonally. Since both nozzles have the same structure, the subscripts α and β will be omitted unless necessary.

  The mounting head 6 is fixed to the mounting head body 11 via a mounting head base at an upper portion (not shown), and a selection device that selects a plurality of suction nozzles on the mounting head base and only the selected suction nozzle are provided. A lifting device that moves up and down is fixed.

  The lower part of the apparatus head 6 is roughly divided into a suction nozzle unit 7, a suction nozzle selection unit 61, an air switching valve 62 for switching between air suction and blowing provided for each nozzle, and the presence of the suction nozzle 8. And a line sensor unit 63 that detects the presence / absence of components in the suction nozzle 8 and a suction posture (suction state), and a θ rotation unit 64 that rotates θ to detect the posture and the like of the suction nozzle 8.

  The suction nozzle selection unit 61 includes a nozzle support piece 61 b that is supported by a first cylindrical body 66 b that can rotate around a turning shaft 66 a and supports a support roller 61 a provided at the tip of each suction nozzle unit 7. This nozzle support piece 61a has a notch formed in an angle (approximately 30 °) divided into the number (12) of the suction nozzles 8 in the circumferential direction, and is lifted and lowered at this notch position by a lifting device. A possible lifting support piece 61c is provided. When the first cylindrical body 66b is rotated, only the support roller 61a fixed to each suction nozzle portion 7 is rotated without changing the position of each suction nozzle portion 7. Accordingly, the lifting support piece 61b also rotates with the rotation of the first cylindrical body 66b, and the suction nozzle portion of the support roller 61a on the lifting support piece 61b, 7α in FIG. Accordingly, when the lifting support piece 61b is lowered according to the thickness of the electronic component to be sucked and mounted, only the selected suction nozzle 7α is lowered by a predetermined stroke according to the thickness of the electronic component.

  The line sensor unit 63 protrudes downward from the center of the suction head 6 to detect the presence / absence of a component and a suction posture (suction state) detection unit, a thickness detection unit of electronic components, and a detection of the presence of the suction nozzle 8. It serves as a means (nozzle diameter detection means) and is provided at a substantially central portion of each mounting head 6. Although not shown, the line sensor unit 63 reflects light from an emitting element such as an LED to a conical reflector provided at the lower part thereof, and the reflected light is provided outside the suction nozzle 8. The light receiving unit includes a plurality of light receiving elements (not shown) that are CCD elements.

  The θ rotating portion 64 has a coil 64a1 having a stator side 64a and a magnet 64b1, and is separated by a rotor side 64b indicated by a hatched portion, and can be rotated by a bearing 64c. The θ rotation unit 64 is a mechanism for detecting the suction posture, the thickness of the electronic component, and the like together with the line sensor unit 63 described above. Therefore, the line sensor unit 63 is fixed to the rotor side 64b, and the suction nozzle unit 7 and the air switching valve 62 described later are not fixed. Since the rotor side 64b is basically a contrast, only the left half is shown by hatching.

  Therefore, the suction nozzle unit 7 is lowered and the electronic component 30 is sucked and taken out from the component supply unit 13 (see FIG. 1). After the lift, the line sensor unit 63 is rotated by the θ rotation unit 64 and sucked during the rotation. Since the electronic component 30 attracted by the nozzle portion 7α is located between the reflector and the light receiving unit, the presence / absence detection of the component is detected by detecting the height position of the lower end surface of the electronic component 30 at a plurality of positions. It is possible to detect the suction posture, detect the thickness of the part sucked and held by the suction nozzle 8α, and the like.

Next, the suction nozzle portion 7 will be described with 7α. The suction nozzle unit 7 is roughly divided into a suction nozzle body 9 and a suction nozzle 8 that can be attached to and detached from the suction nozzle body 9. Since the suction nozzle 8 will be described in detail later, the suction nozzle body 9 will be described here.
The suction nozzle body 9 has a cylinder 91 fixed to the support roller 61 a, an elongated suction passage 92 inside the cylinder 91, and a nozzle holder 93 that fixes the suction nozzle 8 at the tip of the suction passage 92. Further, a circled portion shown in the middle of the cylinder 91 is a bearing provided between the rotor side 64b. The nozzle holder 93 surrounds an insertion portion 83 of the air filter 10 of the suction nozzle, which will be described later, and also serves as a leakage preventing means for preventing air leakage from the insertion portion. The drawer part A in FIG. 2 is an enlarged view of the vicinity of the nozzle holder 93. The suction nozzle 8 is attached to the nozzle main body 9 by engaging an engagement portion 93a provided on the nozzle holder 93 at the tip of the cylinder 91 with an engaging projection 82b of the adsorption nozzle 8 described later.

  Next, the air switching valve 62 will be described. The air switching valve 62 moves the valve body 62a1 up and down with a solenoid 62a2 to control the suction and blowing of air from the suction nozzle portion 7α. Further, on the upstream side of the air switching valve 62, a suction nozzle body filter portion 62b for protecting the solenoid 62a2 is provided. The air switching valve 62 and the suction nozzle body filter portion 62b are provided adjacent to each suction nozzle portion 7 in a pair. In FIG. 2, since the air switching valve of the suction nozzle portion 7α is complicated, it will be described using the valve of the suction nozzle portion 7β. Note that the air switching valve 62 and the suction nozzle body filter part 62b do not move up and down, and the suction nozzle part 7 moves up and down. The state of the suction nozzle portion 7α shown in FIG. 2 indicates the state of suction of air that sucks the electronic component 30, and the flow when the flow of air at that time is substituted by the valve of the suction nozzle portion 7β is indicated by arrows. . The flow of air from the suction passage 92 is controlled by a valve 62a, passes through a hollow pivot 66a, and communicates with a vacuum source (not shown). Conversely, in the case of air blowing, the air supply source (not shown) communicates with the hollow turning shaft 66a, and the passage is selected by the valve 62a and communicates with the suction nozzle 8.

3A and 3B show the suction nozzle 8 and the air filter 10 according to the present embodiment. FIG. 3A is a perspective view, FIG. 3B is an external view of the suction nozzle 8, and FIG. A cross-sectional view and (d) a top view of an insertion portion to be described later are shown. The suction nozzle is 8, a fitting portion 82 for fitting the suction nozzle into the nozzle holder 93 described above, an insertion portion 83 for inserting the air filter from the side of the nozzle, and a convex shape that is gripped when the suction nozzle 8 is attached and detached. It consists of a grip portion 84 having an elongated shape and a suction portion 86 provided with a nozzle hole 85 at the tip. Further, inside the suction nozzle 8, there is a suction passage 81 for suctioned air whose diameters become narrower 81a, 81b, 81c toward the tip of component suction.
The fitting part 82 is divided into a plurality of parts (in the figure, divided into four parts) as shown in the figure (a), and the gripping part 84 is formed by the spring force of the divided part 82a and the locking convex part 82b provided at the tip. It has a structure that can be attached to and detached from the nozzle holder 93 by artificially applying a force to the nozzle holder 93.

  As shown in FIGS. 2C and 2D, the insertion portion 83 has an insertion groove 83A for inserting the air filter 10 from the side and a suction passage hole 83c that forms a part of the air suction passage 81a. Of course, the diameter of the suction passage hole 83c needs to be smaller than the diameter Df of the air filter. As shown in FIG. 4D, the insertion groove 83A is provided on the opposite side of the insertion hole with an insertion hole 83a having a diameter D2 and a height T2 substantially the same as the diameter Df and thickness Tf of the air filter 10. An extrusion rod insertion hole 83b for inserting the extrusion rod when the air filter 10 is removed is provided.

  The adsorbing portion 86 has a smaller outer diameter toward the tip. Corresponding to the outer diameter, there is a suction passage 81 having suction passages 81a to 81c whose diameter decreases toward the tip. As a result, for example, even a small component of 0.2 mm × 0.4 mm can obtain a sufficient suction force and can be reliably suctioned. However, in the case of relatively large parts, it is not always necessary to reduce the diameter.

  Finally, in addition to the functions described above, the gripping portion 84 has a function of fixing the suction nozzle to an air filter insertion jig described later when the air filter 10 is mounted. Therefore, it has an elongated convex shape on the insertion hole 83a side.

  FIG. 4 is a perspective view showing an embodiment of the air filter insertion jig 2 for inserting the air filter 10 into the suction nozzle 8 described above. The air filter insertion jig 2 is roughly composed of a cartridge part 3 which is an air filter supply means and an air filter insertion part 4 for inserting the air filter 10 into the suction nozzle 8.

FIG. 5 is a diagram showing the cartridge unit 3. The cartridge part 3 is roughly composed of a cartridge 31 containing a plurality of air filters 10 and an air filter sending part 32 for sending the plurality of air filters 10 to a desired position of an air filter insertion part 4 to be described later. The cartridge 31 includes two plate-like cases 31a having semicircular elongated recesses, a cylindrical stock portion 31b formed by two semicircular recesses when the two cases 31a are combined, and the two cases. Is composed of fixing screws 31c for fixing the both sides of the stock portion 31b. In the above configuration, the air filter can be easily set in the cartridge 31 by placing a plurality of air filters on the semicircular portion of the case 31a and combining the two cases.
The air filter delivery unit 32 sandwiches the delivery rod 32a for feeding the air filter 10, the handle 32b for pushing the delivery rod, the coupling rod 32c for connecting the delivery rod and the handle, the case 32d and the cartridge 31 from both sides, and the air filter delivery. 4 includes a fixing leg 32e shown in FIG.
Therefore, the air filter 10 in the stock part 31b can be sent out one by one by artificially pushing the handle 32b.

  In the above embodiment, the handle 32b is artificially pushed, but by applying a certain force in the delivery direction with a spring or the like, if there is a gap at the tip of the stock part 31b, the air filter 10 is automatically inserted into the gap. May be sent out automatically.

  On the other hand, as shown in FIG. 4, the air filter insertion portion 4 is roughly divided into a base block 41, an insertion portion 42 for inserting the air filter 10 into the suction nozzle 8, and a suction nozzle 8 fixed to the air filter insertion portion 4. It consists of a nozzle fixing part 43.

  FIG. 6 is a cross-sectional view taken along line AA shown in FIG. 4 and shows the state of the air filter insertion portion 4 and the cartridge 31 when the cartridge portion 3 is set in the air filter insertion portion 4. FIG. 7 is a perspective view when the upper portion of the air filter insertion portion 4 is removed.

  The insertion portion 42 extends from a slide claw 42a and a slide claw 42a which are artificially operated slide gripping portions, and the tip thereof has a width and thickness slightly smaller than the diameter Df and the thickness Tf of the air filter 10. A plate-shaped filter insertion rod 42b having a slide claw 42a, a nozzle removal rod 42c for separating the suction nozzle 8 from the nozzle fixing portion 43 after the air filter 10 is inserted into the suction nozzle 8, and a slide claw There is a pressing means provided between 42a and the nozzle fixing portion and having a return force in the direction of arrow C. The pressing means includes a pressing spring 42d and a guide groove 42f (see FIG. 7). The tip end side of the filter insertion rod 42b is slightly thinned for easy insertion. The lengths of the filter insertion rod 42b and the nozzle removal rod 42c are such that when the filter insertion rod 42b completes the insertion of the air filter 10 into the suction nozzle 8, the nozzle removal rod 42c contacts the side of the air filter. To do. When the slide claw 42a is further pushed toward the suction nozzle side, the nozzle release rod 42c pushes the side portion of the air filter 8, and when the slide claw 42a comes into contact with the stopper portion 43c, the suction nozzle 10 is moved to the air filter insertion portion. 4 can be removed.

  Further, as shown in FIG. 7, the base block 41 has a cylindrical shape for aligning the slide claw guides 41a and the nozzle fixing portions 43 provided on both sides of the slide claw in order to define a slide path 42e of the slide claw. A protrusion 41b, a screw hole 41c for fixing the nozzle fixing portion 43, a slide surface 41d (see FIG. 7) on which the insertion rod 42b slides, and a nozzle release rod through hole 41e (see FIG. 6) on which the nozzle release rod 42c moves. Have.

Further, the nozzle fixing portion 43 will be described mainly with reference to FIG. The nozzle fixing portion 43 includes an upper block 43A and a lower block 43B.
The upper block 43A fixes an insertion rod moving path groove 43a and a cartridge 31 for forming a moving path in which the filter insertion rod 42b moves, and discharges the air filter 10 to the insertion rod moving path groove 43a at the tip side thereof. A cartridge fixing groove 43b (see FIG. 4) having a discharge port 43b1 for carrying out, a guide hole 43c1 for the aforementioned pressing spring 42d, a stopper portion 43c that serves as a stopper by defining the operating range of the slide claw 42a, and a suction nozzle 8 has an upper installation portion 43d into which the fitting portion 82 and the insertion portion 83 are inserted, and a screw hole 43e (see FIG. 4) for fixing the upper block 43A to the base block 41. The insertion rod moving path groove 43a may be provided on the slide surface of the base block at 41d without being provided in the upper block.

  On the other hand, the lower block 43B is formed of the upper surface of the lower block and the base block 41, and includes an air filter fixing portion 43h for inserting and fixing the gripping portion 84 of the air filter 10 and a release rod on which the nozzle release rod 42c moves. There are screw holes (not shown) for fixing the movement path hole 43 i and the lower block 43 B to the base block 41.

  FIG. 8 shows a mounting flow for mounting the air filter 10 using such an air filter insertion jig 2, and FIG. 9 shows the state at that time. In FIG. 9, in order to facilitate understanding, a perspective view excluding the upper wind block 43 </ b> A of the nozzle fixing portion 43 is shown.

  First, (1) the suction nozzle 8 is removed from the suction nozzle body 9. (2) The push rod is inserted from the push rod insertion hole 83b of the suction nozzle 8, and the used air filter is pushed out. Thereafter, (3) the portion on the insertion hole 83a side of the gripping portion 84 of the suction nozzle 8 is inserted into the air filter fixing portion 43h, and the suction nozzle is fixed to the air filter insertion jig 2 (FIG. 9 (a)). (4) The slide claw 42a is operated, and one air filter is pushed out from the cartridge 31 by the filter insertion rod 42b in the manner of dropping the dart, and inserted into the insertion groove 83A of the suction nozzle (FIG. 9 (b)). (5) When the slide claw 42a is further pushed to the suction nozzle side, the nozzle detachment bar 42c pushes the side portion of the air filter, and the suction nozzle 10 is removed from the air filter insertion portion 4 (FIG. 9 (c)). At this time, the slide claw 42a contacts the stopper portion 43c and cannot be pushed any further. (6) The suction nozzle 8 is mounted on the suction nozzle body 9.

  In the above flow, the set time of one air filter is about ten seconds corresponding to about 1/6, which is 50 seconds shorter than the conventional one, and it can be carried out reliably even if it is not an expert. The number of suction nozzles is 60 per electronic component mounting device, and the shortening effect is as large as about 50 minutes by simple calculation. The conventional method sometimes fails, and there is a problem of perseverance associated with detailed work, and the actual effect is expected to be several times.

  In the above flow, each suction nozzle is performed one by one. However, a plurality of suction nozzles may be mounted on the mounting head 6, and the above flow may be performed in units of the plurality.

  In the above embodiment, the cartridge is provided in order to improve the work efficiency. However, if the number of air filters to be inserted is small, the work is carried out while directly placing the air filter on the tip of the air filter insertion rod. May be. Therefore, the cartridge portion is not necessarily required.

  According to the embodiment described above, the air filter can be easily replaced with a simple structure in which the air filter is inserted from the side into the suction nozzle side portion, and an electronic component mounting apparatus with a high operating rate can be provided.

  Further, according to the embodiment described above, it is not necessary to provide an extra component such as an O-ring in the mounting head, and it is possible to provide an electronic component mounting apparatus having a suction nozzle portion that can be applied to a small component.

Further, in the present embodiment described above, the suction nozzle holder serves to prevent air leakage during suction of the suction nozzle 8 as shown in the drawing (enlarged view) of FIG.
As described above, in the above-described embodiment, the air leakage prevention means at the time of suction is provided in the suction nozzle main body, but a partly spaced ring may be inserted outside the insertion portion of the suction nozzle to serve as the air leakage prevention means.
Further, in the case of a small part of 0.2 mm × 0.4 mm or 0.3 mm × 0.6 size, when the side surface of the air filter is made of an epoxy material as an air filter, no leakage preventing means is necessary. Depending on the material of the filter or the size of the part to be adsorbed, it is possible to mount the part with peace of mind by providing a leakage prevention means.

  In the present embodiment described above, since the air filter can be provided in the suction nozzle, the air passage between the suction nozzle 8 and the filter 62b, for example, dust is attached to the suction passage 92, or the passage becomes narrower. Can prevent clogging. As a result, there is no need to periodically remove and clean the suction nozzle body on which the suction nozzle is mounted, and an electronic component mounting apparatus with a high operating rate can be provided.
