Description

DETAILED DESCRIPTION OF THE INVENTION TECHNICAL FIELD OF THE INVENTION The present invention relates to an automatic electrical component insertion machine that can automatically insert various types of electrical components onto printed circuit boards.

"Prior Art and Problems" As a parts supply method for an automatic electric parts insertion machine that inserts electric parts into a printed circuit board,
Taping (attaching lead wires of electrical components to tape)
This is a method in which a group of assembled electrical parts (component collection band) is stored in a magazine in many bands and of various types, and the electrical parts are taken out one by one from there and transported and supplied to the insertion head using a fan arm or a turning machine. This method is better than a supply method in which parts are stacked individually (individually) and stored in a hopper in the magazine, and from there, parts are passively fed to the insertion tube using air, their own weight, or a circulating belt using a chute or pipe as a guide path. It is also superior in terms of reliability of supply, prevention of damage to parts, and stability of supply speed.

In addition, regarding taping of parts, if parts are arranged sequentially in advance according to the order of insertion, even if a mistake occurs in supplying the parts to the insertion head, inserting the parts from the insertion head to the printed circuit board, or installing them due to some reason, the parts can be replaced with normal parts and the parts can be properly installed. There is a drawback that it is not possible to return to insertion operation. Due to these circumstances, there is currently an insertion machine using the above-mentioned feeding method in which electrical parts of the same type are taped.
1, JP-A-51-116968, JP-A-51-11
No. 5655, etc. However, these methods involve moving the entire large and heavy magazine for parts to be supplied to the insertion head and facing the conveyor arm or rotating disk gripping tool, which causes problems such as inertia, alignment with the conveyor arm and rotating disk, wear, etc. Due to various problems, there is a limit to the following movement of the insertion head, and the insertion machine cannot be increased in speed very much.

In addition, the parts supply system disclosed in JP-A No. 51-115655 involves sequentially arranging the parts from the magazine onto a rotating disk in the order in which they were inserted, which eliminates the disadvantages of sequential taping. Not only is it troublesome to replace parts due to errors in parts insertion, but also the parts transport device on the insertion head side is forced to move back and forth in a complicated manner, and the process of receiving parts into the insertion head is complicated. Intermediary conveyance equipment and requirements for the movement, etc.
The structure and operation require a long time to supply parts. 1

The above is an outline of the main configuration of the feeding device 20 of the present invention in the insertion machine 1, and each of the members 21 to 95 will be explained in detail below.

First, regarding the configuration of the magazine 21 and the electrical parts drawer 26, at the rear of the main body base 1, the magazine 21 uses the frame 11 as a fixed support frame at both ends, and has various parts collection bands Bl, B2, A creel 24 for storing windings is fitted in a rotatable manner, and the front edge 25'' of the bottom plate 25 facing the table 2 side is connected to the rotating disc 46 (hereinafter simply referred to as a disc). It has a concave shape with the axis 49'' as a radius, and faces the outer circular edge of the disk at a constant distance J'', and on the front edge there are the same number of component drawers 26 (hereinafter simply called drawers) as the creel 24. holders) are lined up at equal intervals that match the installation extension line (radial line) of each gripper 50 on the disk 46, and guide rollers 27 are arranged from each creel 24 to these.
. . . , part collection bands Bl, B 2 .

The drawer 26 has component collection bands Bi, B2, etc. on the circumference.
Feed protrusion 29 that meshes with the small hole 28 (drilled at a parallel pitch between parts P... to be held) of...
A roller 30 having ... is integrally fitted with a ratchet wheel 31 and is rotatably fitted into a pivot pin 32 extending from the bottom plate 25, and is guided by a guide 33 to move forward and backward a small amount with respect to the gripper 50. The feed ball 37 on the circular intervening plate 36 rotates through the pin 35 by the pushing plate 34, which is rotated by the pushing plate 34.
By scratching one tooth of the ratchet 31 and rotating the roller 30 by one part in one reciprocating motion, the parts collection band Bl,
In addition to bringing the parts B2... to the delivery position K on the front end of the push plate 34 facing the gripper 50, there is also a fixing device that stands upright from the push blade 38 on the lower surface of the front end of the push plate 34 and the front end of the bottom plate 25. The blade 39 engages with the push plate when it moves forward, and the part P is at the delivery position K.
. Cut the lead wire at the lower end and separate it from the parts collection band B.
Further, the push plate 34 is moved back from the delivery position K by a restoring spring 40 stretched between the tail end and the bottom plate 25, and the stop pin 41 at the tail end is moved back.
When the opposing gripper 50 moves forward to the delivery position K, the driving member 59 moves the swinging rod 62 to the chain line 62'' via the rod 42, and then moves to the chain line 43''. It is pushed by an arm 43 and moves forward to the delivery position K. Next, regarding the configuration of the rotating disc 46 and the gripper 50,
The disk 46 is connected at its center to the lower end of a vertical shaft 49 which is rotated by a pulse motor 22 via transmission gears 48, 48' with a bracket 47 at the center of the insertion machine as a bearing, and the entire circumference is equally divided radially. Each gripper 50 is attached to the long groove 51...
The base 52 of the holder is slidably disposed in a loose manner, and the gripper is placed in a standby position H where the tip of the return spring 58 between the hooks 52'' and 46'' protruding from the lower surface is sunk into the outer edge of the disc, and one gripper When the container 50 matches the insertion position S of the insertion head 10, the other gripper is in the standby position H and the drawer 2 is placed on the bottom plate 25.
6, and that pair of extractor and gripper is selected for feeding during one cycle of the inserter. Further, the disk 46 is operated by the pulse motor 22 energized by an insertion preparation command from a numerical control device (not shown), from the time when the transfer of parts between the drawer 26 and the gripper 50 is completed to the time when the insertion head 10 starts operating. Within the time period, the gripper 50 holding the electrical component to be inserted (hereinafter referred to as the insertion part) is rotated by the rotation angle that brings it to the insertion position S of the insertion head 10, and the gripper 50 holding the electric component to be inserted (hereinafter referred to as the insertion part) is rotated by the rotation angle to bring it to the insertion head of the gripper holding the next insertion part. The disk remains stationary until it is time to transport it, and then the disk is moved to the center T of the 26 group of drawers.
When a part is delivered in the left quadrant (L), it rotates counterclockwise, and when a part is delivered in the opposite right quadrant (R), it rotates clockwise. The above motion is called a near rotation. Next, regarding the configuration of the gripper 50 and its opening member, the gripper 50 described above has two movable pieces that pull together a stationary plate 53 at the front end of the base 52 by a closing spring 56 at a location in front of the shaft pins 54, 5C. 55,5
5", and the notches 5 on both sides of the front end of the immovable plate 53
3a, 53b and beak portions 55a, 5 at the tip of the movable piece that cover these.
5a'', and the lead wire of the part P is held between the opening cam (member )5
7,57'' and opens, and the drawer 2 is opened at position K.
The lead wires of the parts pushed out by the pushing plate 34 of 6 are received in the notches 53a, 53b, and the movable piece 5 is moved back as it retreats.
Close the 5,55″ opening and firmly clamp the lead wire of the part.
These operations are performed when moving forward from the standby position H by the drive member 59 described below.

In order to increase the reliability of parts delivery, opening cams 57, 57'' that can be reversed in one direction are designed to prevent the tail ends 55b, 55b'' of the movable pieces from passing through the same track when the gripper moves forward and backward. , the gripper may be closed early.Furthermore, the relationship between the gripper 50, the driving member 59, and the selection switch member 69 will be explained.

Drive members 559 radially arranged in each gripper 50
. . . is a spring 63 and a stop plate 6 attached to the lower end of the fan rod 62 which is the pivot pin 61 on the horizontally long crosspiece 60 of the frame 47.
A pushing rod 65 whose rotation is restricted only in the opposite direction to the vertical axis 49 is supported by a joint 64 having a length of 3''. The switch member 6 rests in contact with the pin 67 and selects the top trochanter 68.
9, and in this state, the lower end pushing rod 65 is brought into contact with the gripper base 52 at the standby position H. 70 is a main bevel gear that is loosely fitted on the vertical shaft 49, and a sub-shaft 9 that branches from the drive shaft (not shown) for the insertion head 10 through intermediate bevel gears 9'', 71, 72 and an intermediate short shaft 73.
and intermediate bevel gears 74, 75, 76.
, the spline shafts 77 of the selection switch members 69 in each of the drive members 59 are rotated synchronously via the intermediate long shafts 75''.

Regarding the selection switch member 69, this spline shaft 77
A starting cam 78 having a profile and opening on the end surface and the circumferential surface which rotatably and slidably fit into the shaft 77 is in pressure contact with the bracket 79 on the end of the oblong crosspiece bearing the shaft 77 through the rotation support 8. 80, it has separated from the trochanter 68 of the fan rod. Then, the profile is constantly rotated with the profile facing under the movable piece 82 of the solenoid 81 that is energized by the insertion preparation command from the sequence control device (not shown) and rushes toward the chain line 82'', and rushes when the valley of the profile is reached. When the movable iron piece 82 of the solenoid 81 engages with the peak of the profile, the starting cam 78 moves to the chain line 7' opposite the trochanter 68 against the force of the compression spring 80, and the profile moves the fan rod 62 to the solid line. During the first rotation of the reciprocating movement between the chain line 62'' and the movable iron piece 82, the valley of the profile reaches the movable iron piece 82, and the return movement of the movable iron piece accompanying the demagnetization of the solenoid causes it to be pushed by the compression spring 80 and stand by. By returning to the position, the fanning rod 62 comes into contact with the stop pin 67 again and comes to rest.
When the fan rod 62 moves forward toward the chain line 62'', the push rod 65 pushes the tail end of the trunk 52 and the gripper 50 faces the puller 2.
6, and move the crimp arm 43 to the chain line 43'' on the gripper side via the rod 42.
Even after the gripping and drawing devices collide, the pushing rod 65 remains at the joint 6.
At step 4, the crimping arm is moved forward while being bent in the direction of x, and the above-mentioned state of contact between the two instruments is maintained until the gripper 50 is closed. As a result, the inserted part P at the delivery position K is kept under restraint by the two devices 26 and 50 from beginning to end at the position K, and the part can be quickly cut from the collection band B, delivered to the gripper 50, and held by the gripper. And it will be carried out reliably. Regarding the relationship between the gripper 50 and the latch member 83, from the time when the gripper 50 completes the holding of the inserted component as described above, the push plate 34 of the drawer 26 starts to return the fan rod 62 to its original position. During the accompanying retreat, the push plate 34 separates from the retainer 50, and at this time, the push plate 34 moves through the ratchet mechanisms 31, 37 and the intervening plate 36 to the gathering zone B.
A new part is sent from the creel 24 to the drawer delivery position K by one part, and continues to wait until the next operation.

On the other hand, while the gripper 50 is retreating, the protrusion 84 protruding from the center of the lower surface of the base 52 comes into contact with the latch 85 of the latch member 83, and the gripper 50 is prevented from retreating, and the tip that holds the component is moved to the insertion position S in the insertion head 10. It is regulated to a corresponding meeting position J. The latch 85 is rotatably attached to the bottom end of each elongated hole 51 in the disc 46, and is connected to the leaf spring 86 under the disc from below.
At the standby position H of the gripper 50, the protrusion 8
4 rests with its abdomen in contact with the lower surface of the gripper, and its tip extends to the center of the gripper, and when the gripper 50 advances to the delivery position K, the tip is retracted into the long groove 51 by the leaf spring 86 and its end The surface catches the protrusion 84. When the gripper 50 holding the part P is regulated to the mating position J, the disk 46 rotates and brings the gripper to the insertion position S under the insertion head 10, so that the part P is held without the gripper itself moving back and forth. Both automatically approach the chuck 10a, and soon the insertion head descends to clamp the head of the component with the chuck. Finally, the gripper 50 at the insertion position S, the release member 88, and the hooking member 95
Explain the relationship structure. There is also a gripper 50 on the insertion head side.
A release member 88 is provided to open the movable piece 55 of the gripper in the insertion position S to remove the component from the gripper.
, 55'' are pivotally supported on the frame 47 so as to face the flat tip portions 93a in front of the trapezoidal protrusions 89, 89'',
It also consists of a pushing rod 93 that presses against a release cam 90 on the countershaft 9 by a compression spring 92 that extends between the trochanter 91 and the bracket 12 of the head, and immediately after the chuck 10a of the insertion head holds the component, the tip 93a is swung counterclockwise at the upper part of the release cam 90 reaching the trochanter 91, thereby intervening between the trapezoidal protrusions 89, 89'' on the gripper and opening the movable pieces 55, 55''. At the same time, the vertical rod 96 penetrating the frame 47 of the hanging member 95 presses the trochanter 98 at the top of the removing cam 97 on the subshaft 9, causing the crimp 99 between the frame and the boss 96a to be released.
The tip of the latch 85 that has passed through the through hole 100 of the rotating disk descends against the ridge and pushes down the wing piece 101 of the latch 85, and the tip of the latch 85 that was holding the protrusion escapes from the long groove 51. The gripper 50 is designed to retreat to a standby position H. 1
Function: The feeding device 20 for an insertion machine according to the present invention has the respective parts and their related configurations as described above, and the functions thereof will be explained below.

First, each drawer 26 arranged on a concave circular bottom plate has one electrical component P attached to each component collection band Bl, B2, . . . .

The grippers 50 on the rotating disk 46 face each other at a delivery position K and a standby position H. Now, when the electrical component to be inserted is designated by the insertion preparation command, a pair of solenoid 81 and pulse motor 22 of the selection switch member 69 corresponding to this are energized, and the movable iron piece 82 is moved to the profile of the starting cam 78. make it stand out. Now, from the counter shaft 9 to the intermediate bevel gears 9'', 71, 72, 70, 74, 75,
76 and splined shaft 77, actuating cam 78 rotates and actuates drive member 59 and crimp arm 43 with its profile. Then, the electrical parts P are moved forward to the drawer to move the opposing grippers to the delivery position K where they collide with each other. The delivery will be made. At this time, the electric component P. The push blade 38 and fixed blade 3
It is cut at 9 and held by a gripper 50. When the drive member 59 moves from the high part of the profile to the low part, the push plate 34 returns to its origin and the ratchet mechanism 3
1, 37 feeds the collection band B for one part and creates a new electrical part P. to the delivery position K. On the other hand, the gripper 50 is prevented from retracting by the latch member 83 on the way back from the delivery position K, and is restricted to the receiving position J corresponding to the insertion position S of the insertion head 10. After the above-described transfer operation, the rotating disk 46 is rotated around by the pulse motor 22, and the gripper 50 holding the electric component P is brought to the insertion position S under the insertion head 10 and indexed and stopped. (The above-mentioned indexing technique for the rotating disc 46 is based on a known NC control device.) As a result, the electric component/item P can be automatically brought under the chuck 10a without the need for the gripper itself to advance or retreat. Shortly thereafter, the insertion head descends and is chucked. Immediately after this chucking, the release cam 90 of the release member 88 opens the gripper via the pushing rod 93, and the vertical rod 96 of the latch/unhook member 95 releases the latch 85 by the release cam 97. , the gripper 50 is now retreated to the initial transfer position H, and the transfer and supply operation of the electrical component P from the drawer to the insertion head is completed. As described above, parts can be supplied from the gripper on the rotating deck to the insertion using the chuck 10a of the simple insertion head.
This is done by the lowering gripping operation of the gripper 50 and the component releasing and retracting operation of the gripper 50, so that the parts can be delivered to the insertion head reliably and quickly. Since it has retreated from S to the standby position H, it is lowered to the bottom of the printed circuit board 3 without any hindrance, and after inserting the component, it is raised.

The next electrical component P to be supplied is selected by energizing the electromagnetic solenoid 81 of the selection switch member 69 of the drawer that has the corresponding electrical component, and the selection is completely free. Different parts can be supplied randomly, and the same part can be supplied continuously.

1. As described above, when the feeding device of the insertion machine of the present invention is used, a group of multiple types of component collecting bands each taped with the same type of electrical components is pulled out from a fixed magazine and placed on the bottom plate of the insertion machine. The drawers are guided to each drawer arranged at equal intervals on a concave arc, and grips movable in the outer radial direction are arranged at equal intervals on the entire circumference of the rotating disk facing the concave arc of the bottom plate. The overhead frame of each gripper facing the above-mentioned drawer has a delivery position where the gripper, which has been retracted to the standby position, collides with the drawer to receive and hold the electrical component. Each drive member is provided with a selection switch member for selectively operating a drawer and a pair of grippers in response to an insertion preparation command. In addition to being equipped with a latch member that waits and holds the electrical component 4 that has been received and clamped in the forward motion at the mating position, each drawer is equipped with a ratchet mechanism that advances the component collection band one component at a time by actuation of a drive member. The insertion head for inserting electrical parts is placed in a position where the gripper meets the rotating disk side without a bottom plate. A release member is provided at an insertion position corresponding to the insertion position, and a release member and a latch member of the gripper are provided at this insertion position to release the electrical component after holding the insertion head against the gripper that rotates around from the drawer side and arrives. The rotary disk is supported by a vertical shaft frame and connected to a pulse motor for indexing, and this pulse motor is connected to a subshaft etc. The electric component is connected to the drive member, selection switch member, release member, hanging member, etc., and is rotated from the drawer by one selection switch member arbitrarily selected by the insertion preparation command and energization of the pulse motor. After the magazine is delivered to the gripper on the disk, the insertion head is rotated and fed by the rotation of the rotating disk, making it possible to move the magazine body unlike conventional devices.
In addition to solving the problems of large inertia, mismatching of delivery parts, and wear that occur due to the manufacturing process, different parts can be supplied at random, and the same parts can be supplied continuously, so it is possible to eliminate defective parts in the event of an unexpected accident. Replacement is simple and easy, parts feeding into the insertion head is quick and reliable with a rotating rotating disk, and parts release and retraction are provided in the gripper so that only a simple downward gripping movement of the insertion head is required. Because of the high-speed operation, parts can be delivered to the insertion head reliably and quickly, and it exhibits many excellent effects as a parts feeding device for insertion machines that insert electrical parts at high speed.
