Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a hopper type magazine configured to store chip parts and to supply the stored chip parts one by one in a predetermined direction. The present invention relates to a hopper type magazine that is optimal for use in a component feeder of a chip component mounting device that automatically mounts chips onto electronic circuit boards.

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. Chip component mounting devices are now being used as devices that automatically mount chip components onto electronic circuit boards. In such an apparatus, chip parts are supplied one by one from a magazine of a parts supply machine to a chucking head, and the chucking head grasps and mounts the supplied parts one by one.

However, due to a change in the board mounted by the chip component mounting device, (a) there is a change in the sorting sequence by type of chip components to be supplied, and (b) it becomes necessary to supply a new type of chip component. When this occurs, a so-called setup change occurs in which the magazines are rearranged. This setup change work is essential for efficient operation of the chip component mounting apparatus.

However, a conventional magazine is composed of a parts supply pipe and a magazine case, and during the above-mentioned setup change, it is necessary to remove the magazine case from the parts supply pipe and discharge the parts remaining in the pipe. However, discharging the chip parts from inside the pipe takes a lot of time and is not easy to work with, and it is difficult to confirm whether the chips have been completely discharged or not, and the discharged parts are not completely recovered. It had the disadvantage that it could scatter inside the equipment and cause trouble.

Purpose of the Invention The present invention was made in order to eliminate the above-mentioned drawbacks.The purpose of the present invention is to make it possible to attach and detach the magazine together with the parts supply pipe, thereby significantly reducing the time required to rearrange the magazines for changing types. In addition, it is possible to prevent problems associated with chip parts scattering, etc., and chip parts can be taken out from the magazine extremely easily and reliably by the chucking head. Another object of the present invention is to provide a hopper type magazine that can effectively introduce chip parts stored in the hopper into a parts supply pipe.

SUMMARY OF THE INVENTION In order to achieve the above-mentioned objects, the present invention includes a hopper case section having a hopper for storing chip parts, a guide member with a retainer that guides the hopper case section so as to be able to slide up and down, and a guide member for the guide member. A magazine lower member fixed to the lower part, and a parts supply pipe having one end fixed to the magazine lower member and the other end slidably guided up and down in a through hole in the bottom of the hopper and communicating with the inside of the hopper. and a component delivery member with a return spring that is slidably provided to receive the chip components at the component outlet of the magazine lower member communicating with the component supply pipe and send them out in a predetermined direction. The component feeding member has a chip component receiving through hole that is approximately the same in shape as the chip component and is slightly larger, and in order to allow the chuck claw of the chuck head to pass through this through hole, A cutout hole is provided that extends from one side of the through hole to the other side across the through hole and has an opening at an end of the component feeding member.

With the above configuration, the magazine can be attached and removed together with the parts supply pipe, so there is no need to eject parts from the parts supply pipe when rearranging the magazines, and the time required to rearrange the magazines is therefore greatly reduced. At the same time, troubles associated with parts scattering, etc. are prevented, and chip parts can be taken out from the magazine extremely easily and reliably by the chucking head, and chips stored in the hopper can be taken out very easily and reliably. Parts can be effectively introduced into the parts supply pipe.

Embodiments Hereinafter, reference examples (FIGS. 1 to 10 and FIGS. 13A to 14B) and examples of the present invention applied to a chip component mounting apparatus having two sets of chucking heads in the mounting head will be described. (Figures 11 and 12)
will be explained based on the drawings.

(Schematic explanation of the entire chip component mounting device) In FIGS. 1 to 3, reference numeral 1 denotes a chip component mounting head, which has two sets of chucking heads 2 and 3 at mutually orthogonal positions. 4,
5, and is attached to a rotation shaft 6 which is rotated 90 degrees left and right alternately. According to the rotation of this rotation shaft 6, two sets of tracking heads 2,
3 move between a horizontal position and a vertical position, and in the horizontal position, rotary parts feeders 7 provided on the left and right

Attach the chip parts on top. Note that this board 9
Adhesive for temporarily attaching chip parts is applied to the top by screen printing etc. in advance, and
- By moving the Y-table 8, chip parts are mounted in a preprogrammed order.

In addition, each of the rotary parts feeders 7a and 7b includes
A plurality of magazines 10a, 10b, etc., which are classified according to the size and shape of chip parts, are attached, and the required magazines are moved to predetermined parts supply positions according to the above program. The chip parts in the magazine are then delivered to rotary parts feeders 7a and 7b.
Component delivery devices 11a and 11 provided in each of
The parts are fed out one by one from the parts supply ports 12a and 12b to the chuck portions of the chuck heads 2 and 3 by means of the part b.

Alternate rotation of the mounting head 1 every 90 degrees, feeding of the parts by the parts delivery devices 11a and 11b,
A series of operations such as vertical movement of the chucking heads 2 and 3 and pressing of the gripped parts onto the board 9 are performed by a cam 115a driven by a motor 13 via a reducer 14 shown in FIG. The driving members 16a, 16b, etc., which are interlocked with the cam 215b, etc., are driven in order. Opening/closing of switches that operate in connection with these sequential operations and confirmation of operations related to the program are performed using cam switches 19a, 19b, etc. provided on a cam switch shaft 18 driven via a cam shaft 17. It is done by folding.

(Schematic description of the chip component mounting head) Next, the chip component mounting head 1 is attached to the rotation shaft 6 (FIG. 3) that alternately rotates 90 degrees left and right, as shown in FIGS. 4 and 5. The holding member 25 is made up of a cross-shaped holding member 25, and the two sets of chucking heads 2 and 3 are attached to the holding member 25 in mutually perpendicular positions. The intersection point O of the orthogonal central axes 26 and 27 of these two sets of tracking heads 2 and 3 coincides with the axis of the rotation shaft 6. Each of the chuck heads 2 and 3 includes a chuck portion 43 that can grip a chip component and slide inside the holding member 25, and a chuck portion 43 that can slide within this chuck portion 43 and holds the component gripped by the chuck portion 43 on the board 9.
It is composed of a push part 44 that pushes out upward.

The distal end of the chuck portion 43 has L facing each other.
Letter-shaped fixed side chuck 47 and rotating side chuck 48
The rotary side chuck 48 is configured to be rotatable around a fulcrum pin 51. A tension spring 52 is connected between these chucks 47 and 48.
A wide pawl 53 is provided at the tip of the stationary chuck 47, and a narrow pawl 54 is provided at the tip of the rotating chuck 48. The rotating chuck 48 on the opposite side of the claw 54 with respect to the fulcrum pin 51 is extended in an L-shape in a direction parallel to the fulcrum pin 51, and a pressed portion 56 for opening and closing the chuck is formed in this extended portion. ing. Furthermore, the push part 44
A push rod 66 is provided between the chucks 47 and 48 at the tip thereof, and is slidable between the chucks 47 and 48.

The chuck portions 43 and push portions 44 of the chucking heads 2 and 3 are perpendicular to each other, but are configured to slide within the holding member 25 without interfering with each other. Further, reference numeral 105 shown in FIG. 4 is a sensor attached to the holding member 25 and activated by the pressed portion 56 of the chuck 48 on the rotating side. The sensor 105 confirms the chuck state from when the component is turned on until it is gripped and mounted on the board 9.

Next, as shown in FIG. 1 and FIG.
6 is configured to come into contact with a pressing member 101a provided on the stationary side separately from the mounting head 1, thereby causing the rotating side chuck 48 to move against the tension spring 52 as indicated by the dashed line. Open as shown. 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 tip part is closed by the claw 5.
It was checked between 3.54 and 3.54. The tracking head 2 then rotates 90 degrees and stops at the mounting position while still being checked (Figure 6). 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 1
02a, and the push rod 102a is configured to be pressed via a compression spring. ) Therefore, the chuck part 43 and the push part 44 are moved downward together with the chucked chip part 104 against the compression springs 61 and 79, and the chuck part 43 is at a position where it has no choice but to come into contact with the board 9. Stop. However, since the push section 44 can move forward independently, it continues to move forward and the push rod 66 at the tip of the push rod 66 pushes the tip part 1.
04 onto the substrate 9. However, since the chuck part 43 starts to move forward at this time, the chip part 1
04 is detached from the claws 53 and 54 and attached to the board 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.

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. Then, by alternately rotating the mounting head 1 90 degrees left and right, the tracking head 2
and 3 alternately repeat the operation of receiving parts and the operation of mounting the supplied parts.

Note that the chuck 4 on the rotating side of the chucking head 3
8 is opened by the pressing member 101b.
This is done in the same way as in a.

(Description of parts supply machine) As shown in Figs. 2, 7, and 8, the rotary parts supply machine 7, (7a and 7b are collectively referred to as 7)
I will explain about it.

The upper part supply section 114 has flanges 13 on the upper and lower sides.
an outer central member 138 having a diameter of 6,137 and fitted around the outer periphery of the inner central member 125; Plate member 1
It consists of 39. A ring-shaped stepped outer edge portion 140 of the upper disc member 139 is provided with a lock member for attaching a magazine, which will be described later, at a position corresponding to the escapement 132. A fitting hole 141 and a rod insertion hole 142 are provided at predetermined positions of the upper disc member 139 in positions corresponding to the positioning pin 129 and the female screw hole 130, respectively. On the other hand, three vertical guide shafts 143 are fixed to the upper flange 136 of the outer center member 138 around the circumference, and the upper cylindrical guide member 144 is slidably inserted into the outer periphery of the vertical guide shaft 143. A horizontal plate 146 is attached to the flange 145. Between this horizontal plate 146 and the outer central member 138, three tension springs 147 for return are stretched around the circumference, and these tension springs 147
Normally, the horizontal plate 146 is biased by the roller 12.
2 has been contacted. Further, a holding plate 148 is fixed to the upper part of the vertical guide shaft 143 to connect these parts, and a handle 149 that can be raised and lifted is attached to this holding plate 148.

On the other hand, a handle 150 is provided at the upper part at a position corresponding to the female threaded hole 130 and the insertion hole 142, and a male thread 1 screwed into the female thread 130 is provided at the lower part.
A connecting rod 152 is provided with a connecting rod 51 formed therein. That is, this connecting rod 152 is connected to the holding plate 14.
8 and the inner central member 138 are guided by bearings 153 and 154 provided on the upper flange 136, respectively, and are configured to be movable up and down, and a cylindrical spring receiver 155 with a single flange is inserted into the lower step from below. A compression spring 156 is further inserted into the outer periphery. Therefore, the connecting rod 152 is inserted into the insertion hole 1.
42 into the female screw hole 130, the cylindrical spring receiver 155 descends as it is screwed in, and when its lower end surface contacts the washer 157 on the upper surface of the upper disc member 139, the connecting rod 152 is not screwed in any further. Stop. That is, the cylindrical spring receiver 155 serves as the bolt head of the bolt, and since it is tightened via the compression spring 156, the screw 151 will not loosen. 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 eighth
As shown in the figure, the upper part supply section 114 can be easily removed from the lower sorting rotation section 113.

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 which will be described later are attached, and these remain as they are when the upper part 114 is attached and detached, so that the positioning of the rotating part for the above-mentioned attachment and detachment will not be disturbed.

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.

On both sides of the guide groove 223, presser plates 224a and 224b, which extend inward from the groove 223 from both sides, are attached with bolts 226 via compression springs 225. A rod-type stopper 227 is provided downward in the center of the guide groove 223, and the stopper 227 is biased by a compression spring 228 so that its head protrudes into the guide groove 223 from below. There is. The head of the stopper 227 is formed with an inclined surface 229 facing in the direction in which the magazine is inserted, and the stopper 227 is provided with a rotation stopper (not shown).

Next, when the lower end of the magazine is inserted into the guide groove 223, since the taper 221 is formed at the entrance of the guide groove 223, the guide legs 211a and 211b resist the compression spring 225 and press the presser plates 224a and 22b. It is inserted between the holding plates 224a, 224b and the guide groove 224 while being lifted. Therefore, if the magazine is pushed in as it is, the magazine will move forward, and when its bottom surface comes into contact with the inclined surface 229 of the stopper 227, the magazine will push down the stopper 227 and move forward. And a recess 230 formed on the bottom surface of the lower member 203 of the magazine.
When the stopper 227 and the
0, the magazine stops, and in this state, the magazine is fixed so as not to move up and down, front and back, left and right, and is accurately positioned.

Therefore, when the hopper case 201 is pressed against the compression spring 215 in this state, the hopper case 201 is guided by the guide shaft 202 and slides up and down, and when the pressure is released, the spring force 215 causes the hopper case 201 to move back. do. Therefore, by continuing this operation, the inside of the hopper 205 is connected to the parts supply pipe 20.
4 moves up and down, and the entry of the component into the pipe 204 is facilitated.

On the other hand, when removing the magazine from the parts feeder,
Stopper 227 protruding below the mounting plate 222
When the knob 231 is pulled downward, the stopper 2
27 and the recess 230 are released, the magazine can be easily removed together with the guide shaft 202, component supply pipe 204, escapement 218, etc. by sliding the magazine toward the removal side.

As mentioned above, since the guide shaft 202 is prevented from coming off, the hopper case 20
1 and the lower member 203 will not be separated unexpectedly.

In the magazine of this embodiment, the escapement 218 is integrated with the magazine, so no matter how you change the arrangement of the magazine in the parts feeder, as long as the parts fed into the hopper 205 are the same, the parts and the escapement will be separated. The interaction with the ment always remains the same.

(Description of Parts Delivery Device) Next, the chip parts delivery device will be described with reference to FIG. 9 and FIGS. 13A to 14B.

In order to receive the chip parts supplied one by one from the component supply pipe 167 of the magazine 10 and to send the received parts between the chuck claws of the chucking head 2 (the same applies to 3), the escapement (feeding member) is used. ) 132 and a pivot lever 134 are used. Escapement 13
2 is provided at each mounting position of the magazine 10 on the rotating side of the component feeder 7, and the rotating 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 chip component height (the height of the component coming down from the component supply pipe 167 of the magazine). ing. 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. A compression spring 238 for return is inserted between the internal recess 236 and a stopper 237 fixed to the outer edge 131.
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. 13B, a rectangular through hole is used which has the same rectangular shape as the chip to be supplied but is slightly larger, that is, a shape and size suitable for inserting the descending part as it is. A hole 240 is formed. 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 part 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 part 239 is inserted into the upper surface 23 of the lower annular member 135.
4. 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 13 is pushed by the rotating lever 134.
2 moves onto the chuck claw 53, the chip part 239 remains in a stable state held within the through hole 240, and is moved onto the wide chuck claw 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 242 and moves in the direction of arrow a while holding and chucking the head of the component 239. Therefore, part 239 is escapement 1
Since the parts are chucked while being held in the through holes 240 of No. 32, and then moved to the mounting position through the through holes 240, the parts may fall over or become misaligned when chucked, resulting in a chuck failure. Nothing happens.

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 rotation lever 134 and moves forward again, and the chuck claw 55 of the tracking head 2 returns.
The operation of sending out the parts is repeated between 3 and 54.

What is shown in FIGS. 14A and 14B 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 magazine described in FIGS. 11 and 12 (embodiment of the present invention), the shape of the component receiving portion at the tip of the escapement 218 is exactly the same as that described above. The only difference is that the surface corresponding to the guide surface 234 in FIGS. 13A and 14A, on which parts are placed, is formed within the guide grooves 216, 217 of the lower member 203 of the magazine itself. Therefore, the magazine according to this embodiment of the present invention can achieve the same effects as the magazine according to the reference example.

Effects of the Invention As explained above, according to the present invention, the hopper case portion is connected to the magazine lower member via the guide member, and the component supply pipe fixed to the magazine lower member is communicated with the hopper in the hopper case portion. ing. A slidable component delivery member with a return spring is provided at the component outlet of the magazine lower member that communicates with the component supply pipe, and normally closes this component outlet. Therefore, the magazine is connected to the parts supply pipe,
Parts can be installed and removed in the specified mounting position without spilling them. Since the guide member is provided with a stopper, there is no possibility that the hopper case part will slip out and spill parts during attachment and detachment.

Therefore, according to the present invention, when rearranging magazines, it is no longer necessary to discharge the parts from the parts supply pipe as in the past, which greatly reduces the time required and also eliminates troubles such as parts flying off. This can be prevented and productivity can be significantly improved.

Further, according to the present invention, since the component feeding member is incorporated into the magazine lower member, if the shape of the component receiving portion of the component feeding member is matched to the shape of the components stored in the hopper, mutual interaction between the two is possible. The relationship remains constant. Therefore, when rearranging the magazines, there is no need to rearrange the component delivery members to match the magazines, which is advantageous because work efficiency is further improved.

Further, according to the present invention, in order to enable the chuck pawl of the chuck head to pass through the component receiving through hole of the component delivery member, the chuck claw is inserted from one side of the through hole to the other side. Since a cutout hole is provided that extends toward the side and has an opening at the end of the component delivery member, the chip component is fed into the chip component receiving through hole, which is approximately the same in shape as the chip component and is slightly larger. If the chip component is chucked with the pair of chuck claws of the chuck head and the chuck head is moved so that one of the chuck claws passes through the notch hole, the chip component can be removed from the component feeding member. It can be taken out directly by the chucking head, and this taking out operation is extremely easy and reliable.

Further, according to the present invention, the guide member to which the magazine lower member is fixed to the lower part thereof guides the hopper case part so as to be able to slide up and down, and the component supply pipe has one end fixed to the magazine lower member and the other end to which the guide member is fixed. is guided to be slidable up and down in the through-hole at the bottom of the hopper and communicates with the inside of the hopper, so the opening at the other end of the parts supply pipe is adapted to the vertical movement of the parts supply pipe relative to the hopper case. Therefore, the chip parts are moved up and down relative to the chip parts stored in the hopper, so that the chip parts can be effectively introduced into the part supply pipe.
