Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a component mounting apparatus for automatically mounting 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. As a device for mounting (mounting) chip components onto this electronic circuit board, a sequential mounting method is generally adopted in which chip components are mounted one by one according to a predetermined order so that it can quickly respond to changes in types such as changes in the board. has been done.

However, many of the mounting heads conventionally used for this sequential mounting method are of the suction pick-up type, and although this type is good for square chips with a flat suction surface, it is difficult to handle cylindrical chips. There is a drawback that it cannot be handled. For this reason, chucking type devices have also been used, but conventionally these devices have their own drive source, so they tend to be bulky.

Additionally, this type of equipment is often required to be capable of handling chip parts of different sizes and shapes, such as cylindrical chips and square chips, at the same time. For this reason, rotary types with multiple tracking heads and double head types with two tracking heads arranged in parallel at predetermined positions have been used, but these have complicated mechanisms. However, the disadvantage was that the device became larger.

Furthermore, if the size or shape of the chip part to be gripped differs, the chuck head must be replaced with one that has a size or shape suitable for the chip part. However, a mounting head with only one set of tracking heads is difficult to use, whereas a mounting head with two sets of tracking heads is
Since the combination of the two sets is often changed, it is especially desirable that the device be easily replaceable.

Purpose of the Invention The present invention has been made in view of the above-mentioned circumstances, and one object thereof is to provide a mounting head with two sets of tracking heads, so that the mounting head can be mounted without having a special drive source itself. It is an object of the present invention to provide a component supply device equipped with a miniaturized mounting head in which chip components can be reliably chucked and mounted by a drive source provided separately from the head.

Another object of the present invention is to provide the mounting head with two sets of chucking heads at mutually orthogonal positions, so that chip parts of different sizes and shapes can be handled simultaneously, and these chucking heads The purpose is to make it easy to replace.

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides

Each set of chucking heads includes a fixed chuck for gripping a chip component, a rotating chuck, and a first chuck for urging the rotating chuck in the gripping direction. a chuck section provided with a biasing means; a push section disposed between the two chucks for pushing out the chip component gripped between the chucks; and a push section for biasing the chuck section and the push section in the backward direction, respectively. and second and third biasing means for pressing the rotating chuck in the component supply position so that the rotating chuck opens against the first biasing means. The first pressing means, the chuck section and the push section located at the component mounting position rotated 90 degrees from the component supplying position move forward onto the board against the second and third urging means, respectively. Second and third pressing means for pressing the chuck portion and the push portion, respectively, are further provided separately from the mounting head, and the rotating side chuck is configured to press the first chuck at the component supply position. is opened against the first urging means by the pressure of the pressing means, and when the component is rotated in the mounting direction from the component supply position, it is released from the first pressing means and the first urging means is opened. By being closed by means,
The chuck part and the push part, which are configured to grip the chip parts supplied between the two chucks and which are in the part mounting position, are pressed by the second and third pressing means. The chuck is moved over the substrate against the urging means of the chuck, so that the chip component between the two chucks is mounted on the substrate.

With the above configuration, the mounting head is provided with two sets of tracking heads, and the tracking heads are configured to be operated by a power source provided separately from the mounting head. , it becomes possible to downsize the mounting head.

Also, the two sets of chucking heads in the mounting head allow chip parts of different sizes and shapes to be handled simultaneously, and these chucking heads can be easily replaced.

The intersection point O of 6 and 27 coincides with the center of the rotating shaft 6, and this rotating shaft 6 is perpendicular to each of the central axes 26 and 27.

The holding member 25, which forms a cross shape as described above when combined, is attached to the connecting bolts 28a, 2 as shown in FIG.
When 8b is removed, as shown in Figures 7 and 8,
It is divided into two sets of assemblies 30 and 31 in which chucking heads 2 and 3 are respectively assembled into two sets of holding members 25a and 25b having U-shaped recesses 29a and 29b, respectively. Note that the through holes 32a and 32b shown in FIG.
This is an insertion hole for a connecting bolt that fixes the rotary shaft 6 to the rotating shaft 6.

Next, since the two sets of assemblies 30 and 31 have substantially the same configuration, one of them 30 will be explained with reference to FIGS. 6 and 8.

The holding member 25a has the U-shaped recess 29.
A semicircular groove 34 running in the longitudinal direction approximately at the center of the bottom surface 33 of a, and through holes 37 and 38 passing through U-shaped protrusions 35 and 36 on an extension of the semicircular groove 34 are formed. has been done. Note that through hole 3
Bearings 39 and 40 are provided on the inner surfaces of the grooves 7 and 38, and a semicircular groove 41 is formed approximately at the center of the semicircular groove 34 and perpendicular to the groove 34.

The chuck head 2 includes a chuck portion 43 that grips the chip component and is slidable in the through holes 37 and 38 of the holding member 25a and the semicircular groove 34, and a chuck portion 43 that is slidable within the chuck portion 43. The pusher section 43 pushes out the part gripped by the pusher section 44.

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 is composed of. This stationary side chuck is fixed to the rectangular parallelepiped end 45 with a bolt 49, and the rotating side chuck 48 is fixed to the rectangular parallelepiped end 45 via a fulcrum pin 51 that is locked by an E ring 50.
It is rotatably mounted on the A tension spring 52 constituting the first urging means of the present invention is stretched between both chucks 47 and 48, and a wide claw 53 is provided at the tip of the fixed chuck 47, and a wide claw 53 is provided at the tip of the chuck 47 on the fixed side. A narrow claw 54 is provided at the tip of each of the claws 48 . 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 in its entirety, including the end portion 45, in the axial direction. A semicircular notch 59 having a notch surface 59a perpendicular to the insertion direction of the pin 51 is formed in the central portion of the hollow rod 46 in the portion of the holding member 25a that moves within the semicircular groove 34. There is. 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, and a compression spring 61, which constitutes the second biasing means of the present invention, is attached to the end of the protruding hollow rod 46. Insert. And a round nut 63 with a flange 62
is screwed into the male thread 60 of the hollow rod 46, the compression spring 61 is compressed between it and the holding member 25a, and the round nut 63 is fixed in a predetermined position with the set screw 64, so that the chuck part 43 can be reciprocated. The end face of the rectangular parallelepiped end portion 45 is held stationary at a position where it is in contact with the holding member 25a. This chuck part 4
As described above, when 3 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 threaded hole 72 is provided inside the end of the rod portion 70 in the axial center direction. On the other hand, the outer circumference of the hollow rod 67 is connected to the through hole 5 of the chuck portion 43.
A hollow cap 73 is fixed to one end. Inside this hollow rod 67, in the axial direction, there is an inner hole 75 large enough for a compression spring 74 to be inserted in order from the opposite side of the cap 73, and an inner hole 75 in which the rod portion 70 can slide. The surface hole 76 and this inner surface hole 76
An inner surface hole 77 having a larger inner diameter is formed. A semicircular notch 78 similar to this notch is formed in the middle of the hollow rod 67 at a position corresponding to the semicircular notch 59 of the hollow rod 46.

Next, in order to attach the push part 44 to the holding member 25a, as described above, insert the third biasing means of the present invention into the through hole 57 of the chuck part 43 attached to the holding member 25a from the round nut 63 side on the outer periphery. Insert the hollow rod 67 fitted with the constituting compression spring 79. On the other hand, with both chucks 47 and 48 removed, push the push rod 66 with the compression spring 74 fitted around the outer periphery of the rod portion 70 from the side of the rectangular parallelepiped end 45 of the chuck portion 43 to the inner holes 75 and 76 of the hollow rod 67. Insert into. and semicircular notch 78
If the bolt 81 is inserted into the female threaded hole 72 through the washer 80 and adjusted from the side, the push rod 66
and hollow rod 67 are connected. (After removal, the 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 61 Configured for a weaker spring force. 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. . When pushed in the forward direction against the compression spring 79, the push part 44 can slide in the reciprocating direction within the through hole 57 of the chuck part 43, independently of the chuck part 43. Further, since the hollow rod 67 is connected to the push rod 66 through the compression spring 74 in the reciprocating direction, even if the push rod 66 stops on the substrate, only the hollow rod 67 can 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. Since the assembly 31 is obtained in the same way, the U of the holding members 25a, 25b is
When the letter-shaped recesses 29a and 29b are placed inside and aligned at right angles to each other, the bottom surfaces 33 of the recesses 29a and 29b are formed.
Both holding members 2 are held in close contact with each other, and the U-shaped protrusions 35 and 36 hold both side surfaces 98 of the other.
5a and 25b are combined. Therefore, the connecting bolts 28a and 28b are inserted into the through holes 9 on the side of the holding member 25b.
7a, 97b to the female screw hole 99 of the holding member 25a.
By screwing into holes 99a and 99b, they are connected to form a mounting head 1 having two sets of tracking heads 2 and 3. Further, the rotation shaft 6 is fitted into the circular recess 100 (FIG. 4) for centering of the holding member 25a, and the coupling bolts are inserted into the through holes 32a and 32b and inserted into the female rotation hole. When screwed in, the mounting head 1 is fixed to the rotation 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 able to move into the grooves 41.

In this way, the mounting head 1 is structured so that the assembly 30 or 31 incorporating the chucking head 2 or 3 can be divided into two parts, and since it can be easily attached and detached, the size and shape of the chip parts can be easily adjusted. The tracking heads 2, 3 can be easily replaced according to changes.

In addition, in the coupled state, the chuck portions 43 of the chuck portions 2, 3 and the hollow rods 46, 47 of the push portion 44 have their cross-shaped mating surfaces cut into semicircular shapes 59, 78. , both can freely reciprocate without being interfered with by each other.

(Explanation of Operation of Mounting Head) Next, the chip component mounting 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.
However, it is configured to abut against a pressing member 101a provided on the stationary side separately from the mounting head 1, so that the rotating side chuck 48 resists the tension spring 52 as shown by the dashed line. It will be opened like this.
In addition, this pressing member 101a constitutes the 1st pressing means in this invention with the pressing member 101b mentioned later. 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 101a. 48 is closed by a tension spring 52, and the chip part is chucked between pawls 53,54. 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 rods 102a and 103a at the tips to move downward at approximately the same speed. , and presses down the round nut 63 on the head of the chuck portion 43 of the chuck head 2 and the cap 73 on 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 interior of the push rod 102a, and the push rod 102a is configured to be pressed via a compression spring.) Press lever 102 and push rod 102a
constitutes a second pressing means in the present invention, and the second pressing lever 103 and push rod 103
a constitutes the third pressing means in the present invention. Therefore, as shown in FIG.
3 and the push part 44 are reciprocated downward together with the chucked chip part 104 against the compression springs 61 and 79, and the chuck part 4 is moved as shown in FIG. 9B.
3 stops at the position where it comes into contact with the board 9 or not. However, since the push section 14 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 part 43 starts to move backward as shown in FIG. 9C, so the chip part 104
are detached from the claws 53 and 54 and attached to the substrate 9. When this attachment is completed, the pusher portion 44 also begins to move backward, and both the chuck portion 43 and the pusher portion 44 return to the backward movement position (FIG. 9D).

Then, the tracking head 2 rotates in the direction of arrow b again to receive the parts, but this time, the tracking head 2 that was receiving the parts during the above-mentioned mounting operation of the tracking head 2 3 comes to the mounting position, and the chip parts are mounted in the same manner as above. As the mounting head 1 alternately rotates 90 degrees left and right, the tracking heads 2 and 3 alternately repeat the operation of receiving parts and the operation of mounting the supplied parts.

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

Furthermore, the opening of the rotating side chuck 48 of the chucking head 3 at the component supply position is performed in the same manner as described above by the pressing member 101b which is positioned symmetrically with the pressing member 101a sandwiching the mounting head 1. It will be done.

In this way, the external pressing members 101a, 101b
The chucks 48 on the rotating side are opened by the chucks 48, and the chucks 48 of the chucks 2, 3 are opened by the first and second pressing levers 102, 103 on the outside.
3 and the push section 44 are configured to move forward. Therefore, since the mounting head 1 itself has a structure that does not require a driving source, the mounting head 1
becomes extremely small, and the entire device is accordingly miniaturized.

Also, although it is equipped with two sets of tracking heads, these two sets of tracking heads 2 and 3 are 90
Since the structure is such that it can be attached to a single mounting head 1 that rotates left and right at every turn, the entire device is more compact compared to a device that uses two tracking heads in parallel, and yet it can be mounted on a single mounting head 1 that rotates from side to side. performance.

Next, reference numeral 105 shown in FIG. 4 indicates a holding member 25.
a and 25b, respectively, and this sensor 105 detects when the chuck 48 on the rotary side is open and both claws 53, 54 are gripping the chip part. The protrusion 106 is pressed and turned on. However, this sensor 105
is attached to the holding member 25a (which may be the rectangular parallelepiped end 45 of the chuck portion 43), and the rotating side chuck 48 is attached to the rectangular parallelepiped end 45,
The sensor 105 and the rotating chuck 48 always rotate together through 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 component is not being gripped, so the chucking state of the component is always maintained until the component is gripped by the sensor 105 and mounted on the board 9. It is confirmed.

(Description of Parts Delivery Apparatus) Next, the delivery and mounting of chip parts will be described with reference to FIGS. 10A to 11B.

Magazine 10 (10a, 10b collectively referred to as 10
An escapement (feeding member) is used to receive the chip parts supplied one by one from the parts supply pipe 167 of the chuck head 2 (same as for chuck head 3) and to feed the received parts between the chuck claws of the chuck head 2 (the same applies to chuck head 3). 132 and a pivot lever 134 are used. The escapement 132 is provided at each mounting position of the magazine 10 on the rotating side of the parts supply machine 7 (7a, 7b are collectively referred to as 7),
The rotating lever 134 is provided only at the component supply 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. For example, in the case of a square chip (rectangular chip) 239, the tip of this component receiving portion 233 has a shape as shown in FIG. 10B.
A rectangular through hole 240 having the same rectangular shape as the chip to be supplied and slightly larger, that is, a rectangular through hole 240 with a shape and size suitable for inserting the descending component as is.
is formed. A rectangular notch hole 242 passing approximately through the center of the through hole 240 and having an opening 241 at an 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 fixed receiving position, and while being held in the through hole 240, the component 239 is inserted into the upper surface 234 of the guide member of the component feeder 7.
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 pawl 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 242 and moves in the direction of arrow a while holding and chucking the head of the component 239. Therefore, the part 239 is the 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, and the escapement 13 returns to the predetermined component receiving position by the spring force. When it returns, chip parts 2 will appear again.
39 descends from the magazine and is inserted into the through hole 240, the escapement 132 is pushed by the rotating lever 134 and moves forward again, and the chuck pawl 53 of the tracking head 2 returns. 54
In between, the operation of sending out the parts is repeated.

What is shown in FIGS. 11A and 11B 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.

In the figure, reference numeral 187 is a lower protrusion of the magazine 10, and reference numeral 177 is a rotary lever-type shutter provided therein for opening and closing the component outlet, and reference numeral 180 is a shutter.
is its tip, and reference numeral 189 is the parts feeder 7.
This is a member provided on the front side of the magazine 10 for positioning.

Effects of the Invention As explained above, in the present invention, the mounting head has two sets of chucking heads, and the openings of the rotating side chucks of these chucking heads are provided separately from the mounting head. The chuck portion and the push portion are moved back and forth onto the substrate by the first pressing means, and the mounting head is moved by separately provided second and third pressing means, respectively. In this way, the operation related to the mounting operation of the mounting head is performed by a power source provided separately from the mounting head, except for the energizing means provided in the mounting head, and the mounting head itself is powered by a power source. This is extremely advantageous because the mounting head can be made very compact.

In addition, the mounting of the chip component on the board is not only done by opening and closing the chuck, but also by pressing the push part that is located between the two chucks and pushes out the chip component gripped between the two chucks. This ensures that the chip components are mounted on the board.

Further, two sets of tracking heads are provided on the holding member at mutually perpendicular positions, and the holding member is configured to be separable into two assemblies each having a U-shaped cross section and each having one set of the above-mentioned tracking heads. has been done. For this reason, the two sets of chucking heads can simultaneously handle chip parts of different sizes and shapes, and can mount them with high efficiency.

Furthermore, since the chucking head can be easily replaced together with the two separate holding members, changes in the size and shape of the chip parts can be quickly dealt with. can be installed very efficiently.
