Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a chip component mounting device that automatically mounts chip components onto an electronic circuit board.

Background technology and its problems As the demand for smaller and thinner electronic devices increases, the configuration of electronic circuits shifts from the conventional configuration of electronic components with lead wires to high-density packaging circuits using chip components. There is a tendency. There are two types of devices for mounting (mounting) chip components onto this electronic circuit board: a batch method in which a plurality of chip components are mounted at the same time, and a sequential method in which chip components are mounted one by one in a predetermined order. The batch method is suitable for mass production of a small number of products, but tends to lack flexibility when changing product types such as changing the board, whereas the sequential method has the advantage of being able to quickly respond to product changes. ing.

On the other hand, there are two methods of applying adhesive for temporarily fixing chip parts to the board: screen printing and dispenser.When using screen printing, a screen corresponding to the pattern of the board is prepared in advance. Since it is necessary, the cost will be high if the production volume is small.

On the other hand, when using a dispenser, the substrates to which adhesive has already been applied and the substrates to be applied are lined up in parallel at predetermined positions on an X-Y table, and these substrates are Place the mounting head and dispenser head in the predetermined relative positions above, and set the X-Y position according to the program.
By moving the table, mounting of chip components and application of adhesive to each of the above-mentioned boards were performed in parallel and sequentially. After completion of the process, the substrate coated with adhesive is moved under the mounting head, and the same operation is repeated again. However, this method requires space for at least two substrates, which inevitably increases the size of the device.

Purpose of the Invention The present invention was made in view of the above circumstances, and its purpose is to provide a sequential installation method that can quickly respond to changes in product types, and a method for applying adhesive using a dispenser. To provide a chip component mounting device which can downsize the device by simultaneously mounting the chip components onto a board and applying adhesive, and which can achieve the same mounting speed as the conventional system.

SUMMARY OF THE INVENTION In order to achieve the above objects, the present invention includes a set of chucking heads capable of grasping a chip part and pressing the gripped chip part in the installation direction, and a set of dispenser heads for applying an adhesive. and a chip component mounting head which is supported so as to be rotatable by 90 degrees to the left and right about the intersection of the central axes, and at least one magazine. and a chip component feeder that supplies the chip components one by one to the chucking head, and by alternately rotating the chip component mounting head by 90 degrees, the chucking head can feed the chip components one by one. While receiving the chip parts from the supply machine, the dispenser head applies the adhesive onto the substrate, and the chucking head applies the supplied chip parts onto the applied adhesive. The configuration is such that the operation of putting on the device is performed alternately.

With the above configuration, the chucking head and the dispenser head are attached to one rotating chip component mounting head, and the application of adhesive and the mounting of chip components are performed alternately. , it is only necessary to place one substrate on the XY table, thus making it possible to downsize the entire device. Moreover, the chucking head receives parts while the adhesive is being applied, and the mounting is performed without wasted waiting time, ensuring a mounting speed comparable to that of the conventional parallel type.

Embodiment An embodiment of the present invention will be described below based on the drawings.

It is attached to a rotation shaft 6 which is pivoted by bearings 4 and 5 and rotates 90 degrees left and right alternately. Then, in response to the rotation of the rotation shaft 6, the chucking head 2 grabs the chip component supplied from the rotary component feeder 7 on the left side in FIG. The chip component is mounted on the board 9 on the table 8. On the other hand, when the chucking head 2 is mounting the chip parts, the dispenser head 3 is rotated counterclockwise in FIG. 1 and retracted, and the chucking head 2 receives the parts. An adhesive is applied in between, and the application of the adhesive and the mounting of the chip parts are performed alternately. The movement of the XY table 8 is then performed in a preprogrammed order.

In addition, the rotary parts feeder 7 includes a plurality of magazines 1 divided according to the size and shape of chip parts.
0 is attached, and the required magazines are moved to predetermined parts supply positions according to the above program. The chip parts in the magazine are fed out one by one from a part supply port 12 to the chuck section of the chucking head 2 by a parts delivery device 11 provided in the rotary parts feeder 7.

A series of operations such as rotation of the mounting head 1 alternately every 90 degrees, feeding of the component by the component delivery device 11, vertical movement of the tracking head 2, and mounting of the gripped component onto the board 9 are performed as follows.

The chuck head 2 includes a chuck part 43 that grips the chip component and can slide inside the through holes 37 and 38 of the holding member 25a and the semicircular groove 34, and a chuck part 43 that can slide inside the chuck part 43. The push part 44 pushes out the part gripped by the part 43.

The chuck portion 43 includes a rectangular parallelepiped end portion 45 having a substantially rectangular parallelepiped shape, a hollow rod 46 fixed thereto, and an L-shaped fixed side chuck 47 and a rotating side chuck 48 attached to the rectangular parallelepiped end portion 45 and facing each other. It consists of This fixed side chuck is fixed to the end portion 45 of the rectangular parallelepiped with bolts 49.
The rotating chuck 48 is rotatably attached to the end portion 45 of the rectangular parallelepiped via a fulcrum pin 51 that is locked by an E-ring 50. And both chuck 4

A wide claw 53 is provided at the tip of the fixed side chuck 47.
Furthermore, narrow claws 54 are provided at the tips of the rotating chucks 48, respectively. The end of the rotating chuck 48 on the opposite side of the claw 54 with the fulcrum pin 51 in between is extended in an L-shape in a direction parallel to the pin hole 55, and a pressed part 56 for opening and closing the chuck is provided in this extended part. is formed, and when this part is pressed, chuck 4
8 is configured to open. On the other hand, the outer diameter of the hollow rod 46 is equal to the diameter of the through hole 3 of the holding member 25a.
It is formed in a size that can slide inside 7, 38,
A through hole 57 is formed inside the rectangular parallelepiped, which penetrates the entire rectangular parallelepiped including the end portion 45 in the axial direction. and the holding member 2 in the central part of the hollow rod 46.
A semicircular notch 59 having a notch surface 59a perpendicular to the insertion direction of the pin 51 is formed in the portion of the pin 5a that moves within the semicircular groove 34. A male thread 60 is formed on the outer surface of the end of the hollow rod 46. To attach the chuck portion 43 to the holding member 25a, the hollow rod 46 is inserted into the through holes 37 and 38.
The compression spring 61 is inserted into the end of the protruding hollow rod 46. Then, screw the round nut 63 with the flange 62 into the external thread 60 of the hollow rod 46, compress the compression spring 61 between it and the holding member 25a, and fix the round nut 63 in a predetermined position with the set screw 64. , the chuck portion 43 is biased toward the backward motion side, and is held stationary at a position where the end surface of the rectangular parallelepiped end portion 45 abuts against the holding member 25a. As described above, when this chuck portion 43 is pressed from the outside against the compression spring 61, it can slide within the holding member 25a.

Next, the push rod 44 is composed of a push rod 66 and a hollow rod 67, and the push rod 66 has a flat plate portion 68 at the tip and a
It consists of a circular flange portion 69 and a rod portion 70 which continue to the flange portion 69 and the rod portion 70. Both sides of the flat plate part 68 on the thick side are disposed between the chucks 47 and 48, and the tip of the flat plate part 68 is formed in a size and shape according to the shape of the chip part to be gripped. In the case of the embodiment, a chevron-shaped recess 71 suitable for pressing the circumferential surface of the cylindrical chip is formed. A female screw hole 72 is provided inside the end of the rod portion 70 in the axial direction. On the other hand, hollow rod 67
The outer periphery of the cap is slidable within the through hole 57 of the chuck portion 43, and a hollow cap 73 is fixed to one end. Inside this hollow rod 67, a cap 73 is provided in the axial direction.
an inner hole 75 large enough for the compression spring 74 to be inserted, and the rod portion 70
An inner surface hole 76 in which the inner surface can slide, and an inner surface hole 77 having an inner diameter larger than this inner surface hole 76 are formed. And the hollow rod 4 in the middle part of the hollow rod 67
A semicircular notch 78 similar to this notch is formed at a position corresponding to the semicircular notch 59 of No.6.

Next, in order to attach the push part 44 to the holding member 25a, the hollow rod 67 with the compression spring 79 fitted around the outer periphery is inserted from the round nut 63 side into the through hole 57 of the chuck part 43 attached to the holding member 25a as described above. Insert. On the other hand, with both chucks 47 and 48 removed, push rod 66, which has a compression spring 74 fitted around the outer periphery of rod portion 70, is attached to chuck portion 43.
The hollow rod 67 is inserted into the inner holes 75 and 76 from the rectangular parallelepiped end 45 side. Then, by screwing the bolt 81 into the female threaded hole 72 through the washer 80 from the semicircular notch 78 side and adjusting it, the push rod 66 and the hollow rod 67 are connected. (The removed chucks 47 and 48 are attached to the end portion 45 of the rectangular parallelepiped as described above.) At this time, the compression spring 79 is disposed between the round nut 63 of the chuck portion 43 and the cap 73, and the compression spring 79 is 61, the spring force is weaker than 61. Therefore, the push section 44 as a whole is urged toward the backward motion side by the compression spring 79, and the tip of the flat plate section 68 of the push rod 66 is held in a predetermined relationship position with both pawls 53, 54. . And the push section 44 is
When pressed in the forward direction against the compression spring 79,
The inside of the through hole 57 of the chuck part 43 is inserted into the chuck part 43.
It is slidable in the forward movement direction separately and independently. Also, since the hollow rod 67 is connected to the push rod 66 via the compression spring 74 in the forward direction,
Even if the push rod 66 stops on the substrate, it is also possible for only the hollow rod 67 to move forward independently.

Next, when the chuck part 43 and the push part 44 are attached to the holding member 25a as described above, the notch surfaces 59a, 7 of the semicircular notches 59, 78 of both
8a coincides with the bottom surface 33 of the U-shaped recess 29a of the holding member 25a (the hollow rod 67 is rotated appropriately) to obtain an assembly 30 as shown in FIG. 7.

Next, referring to FIG. 8, the assembly 3 in which the dispenser head 3 is assembled as shown in FIG.
1 will be explained.

The holding member 25b differs from the holding member 25a in that a notch 83 for the rotating chuck lever 48 is not formed, and other than this point, it is completely the same as the holding member 25a, so it has the same function as the holding member 25a. are given the same reference numerals and their explanation will be omitted.

Next, the dispenser head 3 includes a removable case 84 for storing adhesive, and a case mounting member 85 that is integrated with the case 84 and is slidable within the through holes 37, 38 and semicircular groove 34 in the holding member 25b.
and a hollow rod 86 fixed to this mounting member 85.

The case 84 is a cylindrical container having a discharge port 87 protruding from its tip.
Contact plates 88a and 88b that protrude further than the protruding length of the discharge port 87 are provided on both sides of the discharge port 87. A male thread 89 for mounting is formed at a predetermined position on the outer periphery, and an inner surface 9 is formed inside the cylinder.
A press lid 91 that can be slid on is provided.

The case mounting member 85 is also formed in a cylindrical shape, and a female thread 92 is formed inside the case mounting member 85. The case 84 screwed into the female thread 92 is sealed by an O-ring 93 provided on the same inner surface. ing. Further, a recess 94 is formed inside the case mounting member 85 and communicates with the case 84 into which the case 84 is screwed, and an air supply port 95 is provided that communicates with the recess from the outer periphery of the case mounting member 85. This air supply hole 95 is formed as a female threaded hole, and is configured so that an air supply pipe (not shown) into which compressed air is sent periodically is connected to this air supply hole 95. Note that the end of the case mounting member 85 opposite to the case mounting side is sealed, and its outer periphery 96 is formed to be able to slide inside the through hole 38 of the holding member 25b, and a hollow hole with the same outer diameter is formed in this portion. It is integrally connected to the rod 86.

Next, the hollow rod 86 has almost the same structure as the hollow rod 46 of the chuck part 43, and the compression spring 61, round nut 63, etc. are also attached to the chuck part 4.
Since these parts are exactly the same as those in No. 3, the same reference numerals are given to these same parts and the explanation thereof will be omitted.
Similarly, the dispenser head 3 is attached to the holding member 25b in the same manner as in the chuck portion 43 to obtain the assembly 31 of FIG. be. In addition, in the dispenser head 3,
The equivalent of the push section 44 in the chucking head 2 is not used.

Since the assemblies 30 and 31 are obtained as described above, when the holding members 25a and 25b are aligned at right angles to each other with the U-shaped recesses 29a and 29b inside, the bottom surfaces 33 of the recesses 29a and 29b are brought into close contact with each other. , both holding members 25 are held in such a manner that the U-shaped protrusions 35 and 36 hold both side surfaces 98 of the other party.
a and 25b are combined. Therefore, the connecting bolt 2
8a and 28b through the through hole 97 on the side of the holding member 25b.
a, 97b to the female screw hole 99 of the holding member 25a.
By screwing into the parts a and 99b, the two are combined to form a mounting head 1 comprising a pair of chucking heads 2 and a pair of dispenser heads 3. Furthermore, a circular recess 10 for centering the holding member 25a
0 (FIG. 4), and insert the coupling bolts into the through holes 32a and 32b and screw them into the female screw holes of the rotation shaft, the mounting head 1 will rotate. It is fixed to the shaft 6 (not shown).

Note that the bolt head of the bolt 81 is connected to the holding member 2.
When the holding members 5a and 25b are combined, they are disposed within the semicircular grooves 41 of the holding members 25a and 25b, and are configured to be movable within the grooves 41.

In this way, the mounting head 1 is structured so that it can be divided into two parts, the assembly 30 incorporating the tracking head 2 and the assembly 31 incorporating the dispenser head 3, making it easy to attach and detach. Therefore, the chuck head 2 can be easily replaced in response to changes in the size and shape of the chip parts.

In addition, in the coupled state, the cross-shaped mating surfaces of the chuck part 43 and the hollow rods 47 of the chuck part 43 and the push part 44 and the hollow rod 86 of the dispenser head 3 have a semicircular shape 59, Since the notch 78 is provided, both can freely reciprocate without being interfered with by each other.

(Explanation of Operation of Mounting Head) Next, the chip component mounting operation and adhesive application operation of the mounting head 1 will be explained with reference to FIGS. 1, 3, 5, and 9.

As shown in FIGS. 1 and 5, when the tracking head 2 is rotated to the component supply position, that is, to the horizontal position, the pressed portion 56 of the rotating chuck 48 is rotated.
is configured to come into contact with a pressing member 101 provided on the stationary side separately from the mounting head 1, so that the chuck 48 on the rotating side resists the tension spring 52 as shown by the dashed line. It will be opened like this. When the parts are supplied between the claws 53 and 54 and the chuck head 2 starts rotating in the direction of arrow a, the rotating chuck 48 is released from the pressure of the pressing member 101. 48 is tension spring 5
2, the tip part is closed by claws 53, 54.
You will be asked in between. Then, while checking, the checking head 2 rotates 90 degrees and stops at the mounting position. Here, the first and second push levers 102 and 103 shown in FIG. 3 rotate in conjunction with the cam 15, and this rotation causes the push rod 10 at the tip
2a and 103a move downward at substantially the same speed to press down the round nut 63 at the head of the chuck portion 43 of the chuck portion 2 and the cap 73 at the head of the push portion 44, respectively. (Although not shown, the push rod 103a is configured to be able to move freely within the push rod 102a, and
02a is configured to be pressed via a compression spring. ) Therefore, as shown in FIG. 9A, the chuck portion 43 and the push portion 44 are moved downward together with the chucked chip part 104 against the compression springs 61, 79, and the chuck portion 43 and the push portion 44 are moved downward as shown in FIG. 9B. 43 stops at the position where it comes into contact with the substrate 9 or not. However, since the push portion 44 can move forward independently as described above, it continues to move forward, and the push rod 66 at its tip presses the chip component 104 onto the substrate 9. However, at this time, the chuck portion 43 starts to move backward as shown in FIG. When this installation is completed, the pushbutton part 4
4 also begins to move back, and the chuck part 43 and push part 4
4. Both return to the backward movement position (Fig. 9D).

Then, the chucking head 2 again rotates in the direction of arrow b to receive parts, but this time the dispenser head 3, which had been retracted, comes to the mounting position. Here, the first and second push levers 102 and 103 shown in FIG. (The push rod 103a has nothing to press in this case, but it moves forward in the same way as described above.) Therefore, the dispenser head 3 slides within the holding member 25 and moves toward the substrate 9, and stops at a position where the abutment plates 88a, 88b at the tips thereof either come into contact with the substrate 9 or not. At this time, the cam 15
The valve opens in conjunction with the air supply pipe, and compressed air flows into the case 84 from the air supply hole 95 through the air supply pipe.
A predetermined amount of adhesive is applied onto the substrate 9. Although this period is very short, when this application is completed, the valve is closed again by the cam 15, and the press lever 102 moves back, so that the dispenser head 3 also moves back. Then, the dispenser head 3 rotates 90 degrees in the direction of arrow a (to the side opposite to the parts feeder 7), and the chucking head 2 returns to the mounting position.

In this way, the chucking head 2 and the dispenser head 3 are alternately moved to the mounting position by the rotation of the holding member 25, and the mounting of chip components and the application of adhesive are alternately repeated.

Note that when the push portion 44 presses the chip component onto the substrate 9, the compression springs 74 and 79 are compressed to absorb the impact at this time. Further, the tip of the chuck portion 43 and the tip of the dispenser 3 are set so as to be pushed down to a position where they may or may not come into contact with the substrate 9, but due to some error, these tips may not touch the substrate 9. Even if it comes into contact with
This error is absorbed by the compression spring in the push rod 102a, and the impact force is also alleviated.

In this way, the rotating side chuck 48 is opened by the external pressing member 101, and the chuck portion 43 and the push portion of the chucking head 2 are opened by the external first and second pressing levers 102, 103. 44 and the dispenser head 2 are configured to move forward. Therefore, since the mounting head 1 itself does not need to have a driving source, the mounting head 1 can be made very small, and the entire device can be miniaturized accordingly.

In addition, since the structure is such that one set of each of the tracking head 2 and the dispenser head 3 is provided on one loading head 1 that rotates left and right by 90 degrees, these heads are arranged in parallel. The integrated mounting head 1 itself is reduced in size, and the entire device is thereby reduced in size. Moreover, since adhesive application and chip component mounting are performed alternately, there is no wasted waiting time, so a mounting speed comparable to that of the conventional parallel type can be ensured.

Next, reference numeral 105 shown in FIG. 4 is a holding member 25a.
This sensor 105 is a sensor attached to

3 and 54 are gripping the tip part, the protrusion 106 is pressed by the pressed portion 56 of the rotating chuck 48.
is configured to turn on when pressed. However, this sensor 105 is attached to the holding member 25.
a (may be the rectangular parallelepiped end 45 of the chuck portion 43)
The rotating side chuck 18 is attached to the end portion 45 of the rectangular parallelepiped, and the sensor 105
and the rotating side chuck 48 always rotate together by 90 degrees. Therefore, the sensor 105 should always be on until the tracking head 2 opens at the component supply position, grips a component, rotates 90 degrees, and mounts the component on the board 9. That is, if the sensor 105 turns off during this time, it is a signal that the part is not gripped, so this sensor 10
5, the chuck state of the component is constantly checked until the component is gripped and mounted on the board 9.

Further, on the outer edge of the horizontal plate 146, a magazine holder 158 made of iron is arranged vertically downward at a predetermined magazine pitch along the circumference.

With the above structure, when the threaded portion 151 of the connecting rod 152 and the female threaded portion 130 are uncoupled, the upper part supply section 114 and the lower sorting rotation section 113 are disengaged. Therefore, by raising the handle 149 and lifting it upward, the first
As shown in FIG. 1, the upper part supply section 114 can be easily removed from the lower sorting rotation section 113. To connect the two, align the fitting hole 141 with the positioning pin 129, align the inner surface 159 of the outer central member 138 with the outer surface 160 of the inner central member 125, push down the upper component supply section 114, and press the upper component supply section 114 onto the lower sorting rotation section 113. It should be placed on. Then, by turning the connecting rod 152 to connect the two, the two are connected in the vertical direction.

Note that the fitting hole 141 is long in the radial direction and formed into a long hole that fits perfectly in the rotational direction, so it is easy to connect during the above connection, and there is no deviation in the rotational direction after connection, so that the upper part 114 is connected to the lower part 113. It is positioned accurately in the rotational direction, and rotational torque is transmitted from the lower part 113 to the upper part 114. Furthermore, as mentioned above, the upper part 114 and the lower part 113 are connected to the inner surface 159 of the outer central member 138 and the inner central member 125.
Since this is done by fitting with the outer surface 160 of the outer surface 160, the two do not shift in the radial direction due to this fitting. That is, the upper part 114 is precisely positioned and coupled to the lower part 113. On the other hand, the lower sorting rotating section 113 has a gear 1 necessary for positioning the rotating section.
28 and an origin described later are attached, and these remain as they are when the upper part 114 is attached or detached, so that the positioning of the rotating part will not be disturbed due to the above-mentioned attachment or detachment.

Next, as described above, the lower sorting rotation section 113 is rotationally driven by the motor 111 together with the upper component supply section. Similarly, the origin detection sensor 161 provided on the fixed side
is used. That is, the origin of the rotation side that should be the reference is detected by this sensor 161, the rotation of the motor 111 from this origin is counted, and when this count matches the programmed one,
Motor 111 is configured to be stopped. Also, in conjunction with the cam 15, a rotating lever 120 is provided.
When the magazine 10
The hopper case part 166 is the parts supply pipe 16
It moves up and down relative to 7. Although the details will be described later, the escapement 132 is pressed by the rotation of the rotation lever 134 which is also linked to the cam 15.

(Description of Hopper Type Magazine) An embodiment of the hopper type magazine 10 will be described with reference to FIGS. 12 and 13.

The magazine 10 is molded from synthetic resin or the like, and includes an upper hopper case 166, a guide shaft 168 that guides the hopper case 166 in a vertically slidable manner, and a magazine lower member 169 attached to the lower end of the guide shaft 168. The component supply pipe 167 is attached to the lower member 169 and communicates with the inside of the upper hopper case 166.

The hopper case 166 has a narrow box shape, and is provided with a hopper 170 having a bottom surface inclined at a predetermined angle.The hopper case 166 has an outlet at the bottom of the hopper 170 that guides a component supply pipe 167 in the vertical direction.

It is an L-shaped lever that is installed inside the lower member 169 so as to be rotatable around a fulcrum pin 178 fixed to the lower member 169, and is normally biased by a compression spring 179 so that one end 180 of the lever is attached to the part. Exit 175 is closed. However, when the magazine 10 is attached to the component feeder 7 and the other end 181 of the shutter 177 is placed on the component feeder 7, the shutter 177 rotates counterclockwise against the compression spring 179. Then, the component outlet 175 is opened.

A stopper 182 consisting of a pin screwed into the guide shaft 168 is fixed to the guide shaft 168, and the forward protrusion of this pin 182 engages with a long hole 166a formed in the front surface of the hopper case 166. In some cases, the guide shaft 16
8 is prevented from slipping out.

Next, the mounting and locking of the magazine 10 on the component supply machine 7 will be explained.

At the bottom of the vertical magazine holder 158 provided in the component feeder 7, there is a horizontal guide groove 184 with a groove width corresponding to the thickness of the hopper case 166 of the magazine 10, and a cutout groove 185 for the component feed pipe 167. A horizontal holder 186 is provided.

On the other hand, the lower disc member 127 of the parts supply machine 7
A lower protrusion 18 of the magazine lower member 169 is attached to the outer edge 131 of the magazine 10 at each mounting pitch of the magazine 10.
A cutout 188 into which the side surface of the lower annular member 135 is fitted is formed, and the escapement 132 is disposed and configured to slide on the upper surface of the lower annular member 135 that is visible through the cutout 188. A ring-shaped edging member 189 (not shown) is attached to the front surface of this notch 188, that is, to the outer circumferential surface of the outer edge portion 131, in which a portion where the escapement 132 enters and exits is notched (not shown).

Further, the outer edge 140 of the upper disc member 139 has a recessed portion in the center, and guide surfaces 190 that are inclined in the magazine direction (forward) are formed on the protruding side plates. A lock member 192 with a notch 191 formed on the lower surface of each end.
is attached by a guide bolt 193.
The locking member 192 is guided through the elongated hole 194, and the stepped circumferential surface 19 of the upper disc member 139 is
A compression spring 196 tensioned between the magazine and the magazine 5 urges it forward, that is, toward the magazine side. The locking member 192 has a distal end formed at a protruding edge 19 formed on the outer periphery of the stepped outer edge 140.
It is normally stopped by contacting 9,
Also, the release lever 19 is attached to this lock member 192.
7 is installed.

To attach the magazine 10 to the parts supply machine 7,
With the guide shaft 168 fully raised and shortened, the hopper case 166 is first inserted into the guide groove 184 of the lower holder 186 of the magazine holder 158. In this way, the rubber magnet 173 on the back side will be attracted to the iron magazine holder 158, and the hopper case 166 will be attached to the magazine holder 158.
It is fixed at 8. Next, the lower part 169 of the magazine
Push the lower protrusion 187 downward to cut out the notch 18
8, the fulcrum pin 178 protruding from side to side will align with the inclined guide surface 1 of the locking member 192.
90, so that as the lower member 169 is pushed down, the locking member 192 compresses the compression spring 19.
6 and is moved backwards. and fulcrum pin 1
78 reaches the lower end of the inclined guide surface 190, the locking member 192 moves back and the fulcrum pin 178 enters the notch 191 at the lower end and is locked. At the same time, the end portion 181 of the shutter 177
Since it is placed on the upper surface 198 of the stepped outer edge portion 131 of No. 7, the shutter 177 rotates and the component outlet 175 is opened as described above.

That is, in this state, the lower member 168 is locked vertically by the lock of the fulcrum pin 178, circumferentially by the fitting between both sides of the notch 188 and the lower projection 187, and radially by the lock. Member 192
The front surface 187a of the lower protrusion 187 is pressed against the ring-shaped border member 189 by being biased by the lower protrusion 189, whereby the lower protrusion 187 is accurately positioned and fixed to the component feeder 7. Therefore, since the guide shaft 168 attached thereto is also fixed, when the magazine holder 158 moves up and down, the hopper case part 166 is guided by the fixed guide shaft 168 and moves up and down. In this way, hopper 1
Since the parts supply pipe 167 moves up and down inside the hopper 17, by continuing this operation, the hopper 17
Parts inside the pipe 167 are facilitated to enter the pipe 167.

Next, to remove the magazine 10, press the compression spring 196
When the release lever 197 is pushed against this, the lock member 192 is moved back and the fulcrum pin 178 is unlocked, so the lower member 169 is pulled upward in this state. Then, by pulling the hopper case 166 forward, the magazine 10 can be removed from the component supply machine 7 very easily, together with the guide shaft 168, the component supply pipe 167, and the like.
Since the stopper 182 is provided, the hopper case 166 will not accidentally slip out from the guide shaft 166 in this removed state.

Note that the lower member 169 of the magazine 10 is connected to the outer edge 140 of the upper disc member via the lock member 192.
Furthermore, since the hopper case 166 is attached to the magazine holder 158, the parts supply machine 7
When the upper component supply section 114 is attached and detached in , the magazine 10 is attached and detached together with the upper component supply section 114.

(Description of Parts Delivery Device) Next, the chip parts delivery device will be described with reference to FIG. 12 and FIGS. 14A to 15B.

In order to receive the chip parts supplied one by one from the component supply pipe 167 of the magazine 10 and send the received parts between the chuck claws of the chucking head 2, the escapement (feeding member) 132 and the rotating lever are used. 134 is used. The escapement 132 is provided at each mounting position of the magazine 10 on the rotating side of the component feeder 7, and the rotation lever 134 is provided only at the component feeding position on the fixed side.

The escapement 132 is formed into a long rectangular parallelepiped, and the component receiving portion 233 at the tip thereof is formed into a flat plate with a thickness approximately equal to the height of the chip component (the height of the component coming down from the component supply pipe 167 of the magazine). has been done. It is slidably provided in a guide groove 235 in the stepped outer edge portion 131 of the lower circular member 127 of the component feeder 7 and guided by the guide groove 235 and the upper surface 234 of the lower annular member 135. There is. and internal recess 236
A return compression spring 238 is inserted between a stopper 237 fixed to the outer edge 131 and is biased by this spring force.
The escapement 132 has its component receiving portion 233 connected to the component outlet 17 of the magazine 10.
5, so as to accurately return to a predetermined relative position and stop.

Parts receiving section 233 of escapement 132
For example, there is a square chip (rectangular chip) 2 at the tip of the
In the case of No. 39, as shown in FIG. 14B, the chip has the same rectangular shape as the supplied chip but is slightly larger.
That is, a rectangular through hole 240 is formed with a shape and size suitable for inserting the descended component as it is. A rectangular notch hole 242 passing approximately through the center of the through hole 240 and having an opening 241 at the end is formed to intersect with the through hole 240 in the sliding direction of the escapement 132.

On the other hand, the chuck pawl 53 at the tip of the chuck portion of the chuck head 2 is formed wide enough to accommodate the component receiving portion 233 at the tip of the escapement 132, and the chuck pawl 54 is formed in the notch hole. The width is narrow enough to pass through 242.

Since it is configured as above, magazine 1
The component 239 supplied from 0 is inserted into the through hole 240 at the tip of the escapement 132 stopped at a predetermined receiving position, and while being held in the through hole 240, the component 239 is inserted into the upper surface 234 of the lower annular member 135.
placed on top. However, since this through-hole 240 is formed to have almost the same shape and dimensions as the chip component 239 to be inserted, the inserted chip component will not fall or become misaligned within this through-hole 240. . Therefore, from this state, the escapement 132 is pushed by the rotating lever 134.
Even when the tip part 239 is moved onto the chuck pawl 53, the chip part 239 remains in a stable state held within the through hole 240, and is moved onto the wide chuck pawl 53 in this state.

In this state, that is, when the component 239 is placed on the wide chuck claw 53, the escapement 132
When the chuck head 2 is rotated in the direction of the arrow a while being held in the through hole 240, the chuck pawl 54 on the rotation side is closed by the biasing force of the tension spring as described above, and the component 239 is released. Both chuck claws 53,
Checked within 54 hours. At the same time, the narrow chuck claw 54 passes through the notch hole 240 and moves in the direction of arrow a while holding and chucking the head of the component 239. Therefore, part 239 is escapement 13
Since the parts are chucked while being held in the through-hole 240 of No. 2 and then moved to the mounting position after passing through the through-hole 240, there is no possibility that the parts may fall over or become misaligned during chucking, resulting in a chucking failure. Never.

Note that when the chuck pawl 53 passes through the notch hole 242, the rotary lever 134 moves back, so that the escapement 132 is returned to a predetermined component receiving position by the spring 238. When it returns, the chip part 239 descends from the magazine again and enters the through hole 2.
Since it is inserted within 40, escapement 13
2 is pushed by the rotating lever 134 and moves forward again, and the chuck claw 5 of the tracking head 2 returns.
The operation of sending out the parts is repeated between 3 and 54.

What is shown in FIGS. 15A and 15B is a case where the component is a cylindrical chip 243, and in this case, a circular through hole 244 that fits the cylindrical chip 243 is formed. And chuck claw 54
As in the case of the square chip, the notch hole 242 through which the through hole 244 passes has an opening 241 at its end, with its center passing approximately through the center of the through hole 244, and
44, and the width of this rectangle is smaller than the diameter of the through hole 244. Therefore, it is clear that the same effects as in the case of the square chip can be achieved in this case as well.

Effects of the Invention As explained above, according to the present invention, the chip component mounting head, which is supported so as to be rotatable by 90 degrees left and right, has a pair of chuck heads and a pair of chuck heads that are orthogonal to each other at their axes. A dispenser head is provided, and the loading head alternately rotates 90 degrees so that while the charging head is being supplied with parts from a parts feeder having at least one magazine. The dispenser head is configured to alternately apply the adhesive onto the substrate and the chucking head to place the supplied component onto the applied adhesive. .

Therefore, as in the past, two boards are arranged in parallel,
In addition, there is no need to arrange the mounting head and dispenser head in parallel, and only one board can be placed on the X-Y table, making the entire device extremely small and extremely convenient to handle. It is advantageous.

In addition, as described above, since the application of adhesive and the mounting of chip components are performed alternately, there is no wasted waiting time, so that a mounting speed comparable to that of the conventional parallel type can be ensured.
