[Industrial applications]
The present invention supplies taped electronic componentsapparatusIn particular, it relates to speeding up of supply and improvement of durability.
[0002]
[Prior art]
The taped electronic component is one in which the electronic component is held on a tape. For example, electronic components are accommodated in each of the component accommodating recesses formed at equal intervals in the carrier tape, and the openings of these component accommodating recesses are closed by a cover film attached to the carrier tape, so that the carrier tape can be fed. The electronic component is prevented from jumping out of the component receiving recess.
[0003]
One type of electronic component supply cartridge that supplies an electronic component as such a taped electronic component includes a cartridge configured as follows. (A) a holding device for holding a taped electronic component container for receiving a taped electronic component and sequentially feeding out the taped electronic component from the tip; (b) a driving member movable in both forward and reverse directions; And (d) attaching the drive member in the forward direction to feed the taped electronic component based on the forward movement of the drive member without transmitting the movement of the drive member in the reverse direction to the taped electronic component. It is configured to include an urging means for urging and (e) a stopper for defining a forward movement limit of the driving member.
[0004]
The electronic component supply cartridge described in Japanese Patent Publication No. 53958/1990 is one example. In this electronic component supply cartridge, the drive member is a drive lever that can rotate in both forward and reverse directions, and the drive lever is rotated by the drive lever rotation device when the taped electronic component is fed. The drive lever rotation device includes, for example, an engagement member that can rotate in both forward and reverse directions around an axis parallel to the rotation axis of the drive lever, and an engagement member rotation device that rotates the engagement member. And the engagement member is disposed on the front side in the positive rotation direction of the drive lever. The drive lever is biased in the forward direction by the biasing means, and the stopper limits the forward movement limit.
If the engaging member is rotated in the forward direction away from the drive lever, the drive lever is rotated in the forward direction by the urging means, and the taped electronic component is fed. Further, if the engaging member is rotated in the opposite direction, the drive lever is forcibly rotated in the opposite direction by the engaging member against the urging force of the urging means to feed the taped electronic component. Preparations are made. The preparation is to cause a state in which the taped electronic component is fed when the drive lever is rotated in the forward direction. For example, as described in the section of the embodiment, the feeding mechanism of the taped electronic component is provided. In the case where is constituted by a ratchet wheel, a sprocket, or the like, it is necessary to allow the ratchet pawl to move over the number of teeth of the ratchet wheel required for feeding the taped electronic component.
By defining the forward rotation limit of the drive lever by the stopper, the leading electronic component of the electronic components held on the tape of the taped electronic components is always moved to a fixed component removal position. The taped electronic component is sent by the urging force of the urging means, and the urging means follows the urging force necessary for feeding the taped electronic component, that is, the tape by following the forward rotation of the engaging member without delay. It has an urging force for sending the chemical electronic components.
[0005]
[Problems to be solved by the invention]
Therefore, when the drive lever is rotated in the opposite direction against the biasing force of the biasing means, a load is applied to the drive lever and the drive lever rotating device based on inertia and friction of the feed mechanism and the drive lever. In addition, a load based on the urging force of the urging means is also applied. As the feed speed of the taped electronic component increases, the urging force needs to be increased in order to increase the followability of the drive lever, and the load applied to the drive lever and the drive lever rotation device increases, There is a problem that the durability and abrasion resistance must be increased, and the cost increases.
A similar problem occurs when the driving member moves linearly, or when a driving member moving device that moves the driving member by linearly moving the engaging member is used.
The present invention can supply an electronic component at a high speed, and can provide a driving member and a driving member moving device with high durability and wear resistance and at a low cost.apparatusIt has been made as an issue to provide.
[0006]

The drive member is moved in the forward direction by the engagement of the engagement member with the second engagement portion during the movement in the forward direction, and the drive member is further moved in the forward direction after the engagement member is stopped. While the movement is prevented by the stopper, when the engaging member moves in the reverse direction, the driving member is biased by the engagement of the engaging member with the first engaging portion. The size is selected so that it can be moved in the opposite direction against the urging force of the means.
[0007]
[Action]
Electronic component supply configured in this wayIn the device,The engagement member of the driving member moving device,Engagement with the first engagement portion and the second engagement portion of the drive member so as to be relatively movable for a limited distance in the movement direction of the drive memberLet me beYou. In that state,The engagement memberIn either directionWhen movedThe engagement member isThe drive member is engaged with the first engagement portion or the second engagement portion, and is forcibly moved in either the forward or reverse direction. When the driving member is moved in the forward direction, the taped electronic components are sentIsHowever, the movement of the driving member in the forward direction is defined by the stopper.You.The engaging member stops moving before the movement of the driving member is stopped by the stopper, and thereafter the driving member is urged by the urging means to move to a position regulated by the stopper, and in this state, the engaging member is engaged. Gaps are formed between the member and the first and second engagement portions.
[0008]
As described above, most of the feeding of the taped electronic component is performed by forcibly moving the driving member by the driving member moving device, and the urging means performs the tape forming at the end stage of the feeding of the taped electronic component. What is necessary is just to have an urging force large enough to move the electronic component, and it is possible to make the urging force smaller than before. In particular, if the driving member moves to a position defined by the stopper due to the inertia imparted to the driving member and the feed mechanism during the forcible movement, the biasing means causes the driving member to contact the stopper. Later, it can have a very small biasing force to prevent it from returning in the opposite direction.
When the engaging member is moved in the opposite direction, the driving member is moved against the urging force of the urging means to prepare for feeding the taped electronic component. Since the power is small, the load applied to the driving member and the driving member moving device can be small.
[0009]
【The invention's effect】
As described above, according to the present invention, it is possible to supply the electronic component at high speed while reducing the urging force of the urging means, and it is possible to reduce the load on the driving member and the driving member moving device. The driving member and the driving member moving device need to have a strength capable of withstanding a load based on large inertia when the taped electronic component is sent at a high speed. The load can be reduced to the extent that the urging force can be reduced, the durability and wear resistance are improved, and the electronic component supply cartridge and the driving member moving device can be configured at low cost.

Have been.
[0034]
The drive lever 86 is rotated by a drive lever rotation device 200 (see FIG. 2) provided at the component supply position of the index table. The drive lever rotation device 200 has an engagement lever 202 and an engagement lever rotation device 204 for rotating the engagement lever 202. The engagement lever 202 is attached to the frame 206 so as to extend downward on a shaft 208 rotatably mounted on an axis parallel to the rotation axis of the drive lever 86, and has an engagement roller 210 at its lower end. Is rotatably mounted.
[0035]
Another lever 212 is attached to the shaft 208 so as to extend substantially horizontally, and is rotatably connected to a lower end portion of an elevating rod 214 arranged vertically. The other end of a lever 216 whose one end is rotatably attached to the frame 206 by a shaft 215 is rotatably connected to the upper end of the lifting rod 214. A driven roller 220 as a cam follower is rotatably mounted on the lower surface of the intermediate portion in the longitudinal direction of the lever 216, and is pressed against the cam surface 226 of the cam 224 by a spring 222 disposed between the lever 216 and the frame 206. ing. The cam 224 is rotated by an index motor that rotates the index table, and the engagement lever 202 is rotated in the forward or reverse direction via the lever 216, the lifting rod 214, and the lever 212.
[0036]
The cam surface 226 does not rotate the engagement lever 202 while the index table is rotated, stops the index table, moves the component suction head 110 up and down, and stores the electronic component 14 on the carrier tape 18. When taking out from the concave portion 28, the engagement lever 202 is rotated, and the drive lever 86 is rotated to feed the taped electronic component 16 and wind up the cover film 20.
[0037]
The drive lever 86 of the component supply cartridge 12 is urged by the spring 94 when the first and second engagement portions 190 and 192 are disengaged from the engagement lever 202, and moves to the clockwise rotation end. It is in a rotated state, and is also in this state when waiting for removal of the electronic component 14 by the component mounting head 110 during rotation of the index table. As described above, with respect to the component supply cartridge 12 waiting for the removal of the electronic component 14, the position of the engagement lever 202 is such that the engagement roller 210 is separated from both the first engagement portion 190 and the second engagement portion 192. It has been adjusted to be located. Therefore, when the component supply cartridge 12 is moved during rotation of the index table, and the one that supplies the electronic component 14 among the plurality of component supply cartridges 12 is positioned at the component supply position, the engagement roller 210 does not interfere. Instead, it fits between the first engaging portion 190 and the second engaging portion 192.
[0038]
Next, the operation will be described.
When the engagement lever 202 is rotated counterclockwise in FIG. 1, the drive lever 86 is rotated clockwise in FIG. 1, and the tape drive plate 82 is advanced. As a result, the rotating plate 64 is rotated counterclockwise, and the ratchet pawl 66 moves together with the rotating plate 64 to rotate the ratchet wheel 62, and the sprocket 58 is rotated to feed the taped electronic component 16.
[0039]
The rotation of the engagement lever 202 stops before the drive lever 86 rotates and the ratchet pawl 66 hits the protrusion 112, and thereafter, the drive lever 86 is urged by the spring 94 to move the ratchet pawl 66 to the protrusion 112. , And in a state where the rotation is defined, the engagement roller 210 is separated from both the first engagement portion 190 and the second engagement portion 192. Further, the cover drive plate 98 is simultaneously advanced by the rotation of the drive lever 86, and the cover 52 is advanced together with the taped electronic component 16.
[0040]
When the drive lever 86 is rotated, the moving roller 142 moves, and loosens the cover film 20 located between the fixed roller 140 and the take-up reel 116. The amount of the slack is set to be equal to or longer than the length corresponding to the feed length of one pitch of the taped electronic component 16, and the taped electronic component 16 is fed without the cover film 20 being peeled off.
[0041]
Along with the rotation of the drive lever 86, a force is applied to the take-up lever 152 in a counterclockwise direction in FIG. 1, that is, a direction of turning in a direction opposite to the cover film winding direction. The rotation of the take-up lever 152 in the direction opposite to the cover film take-up direction is permitted by the first one-way clutch 160, and the rotation of the reel support member 164 in the same direction is prevented by the second one-way clutch 162. Only the take-up lever 152 rotates, and the reel supporting member 164, that is, the take-up reel 116 does not rotate.
[0042]
By the feeding of the taped electronic component 16, the electronic component 14 housed in the leading one of the at least one electronic component housing recess 28 from which the cover film 20 has been peeled is positioned in the notch 126 of the cover 52. At the same time, the both ends of the electronic component 14 in the direction orthogonal to the feed direction are covered by the tongue pieces 124 and are prevented from jumping out of the electronic component accommodating recess 28 to the component take-out position directly below the component suction head 110. Can be In this state, the component supply cartridge 12 waits until the component suction head 110 is moved to the component supply position by the intermittent rotation of the index table and the electronic component 14 is taken out.
[0043]
When the component suction head 110 is lowered to take out the electronic component 14, the cover 52 of the component supply cartridge 12 is retracted. At this time, the engagement lever 202 is rotated clockwise in FIG. 1, the drive lever 86 is rotated counterclockwise, and the tape drive plate 82 and the cover drive plate 98 are retracted. At this time, the ratchet pawl 66 only passes over the teeth 70 of the ratchet wheel 62 and does not rotate the ratchet wheel 62, the taped electronic component 16 is not retracted, only the cover 52 is retracted, and the electronic component 14 is removed from the notch 126. As a result, the component suction head 110 can take out the electronic component 14 from the component housing recess 28. Further, the next electronic component 14 is located in the notch 126.
[0044]
The component suction head 110 is moved down in synchronization with the retraction of the cover 52. The component suction head 110 is lowered at the timing of contact with the electronic component 14 before the tongue piece 124 retreats and comes off the electronic component 14. The electronic component 14 is sucked by the component suction head 110 while being covered with the tongue piece 124 and prevented from jumping out of the electronic component housing concave portion 28. The suction head 110 is raised to take out the electronic component 14 from the electronic component housing recess 28.
[0045]
When the drive lever 86 is rotated to retreat the cover 52, the moving roller 142 moves to the left in FIG. 1, and the slack of the cover film 20 previously given at the time of feeding the taped electronic component 16 is eliminated. At the same time, the take-up lever 152 is urged by the spring 158 to apply a clockwise turning force in FIG.
[0046]
The relative rotation of the take-up lever 152 in the cover film winding direction with respect to the reel support member 164 is prevented by the first one-way clutch 160, and the rotation of the second one-way clutch 162 in the cover film winding direction of the reel support member 164 is prevented. When the take-up lever 152 is pulled by the spring 158, the take-up lever 152 and the reel support member 164 rotate integrally, and the take-up reel 116 frictionally engaged with the reel support member 164 also moves. Then, the cover film 20 is wound up by one pitch of the taped electronic component 16.
[0047]
As the diameter of the cover film 20 wound around the take-up reel 116 increases, the rotation angle of the take-up reel 116 required to wind the cover film 20 by one pitch of the taped electronic component 16 increases. Become smaller. This change in the rotation angle is absorbed by the change in the size of the gap between the arm portions 144 and 154. After the cover film 20 has been peeled off by one pitch, the tension of the cover film 20 becomes greater than the urging force of the spring 158, and the take-up reel 116 and the take-up lever 152 do not rotate. A gap is formed between the cover film 20 and the outer diameter of the cover film 20.
[0048]
After the component suction head 110 takes out the electronic component 14 in this manner, the drive lever 86 is rotated clockwise in FIG. 1 by the counterclockwise rotation of the engagement lever 202, and the cover film 20 is peeled off. Of the at least one electronic component housing recess 28, the electronic component 14 housed in the first one is sent to the component pick-up position and is in a state of waiting for the next pick-up.
[0049]
When it is necessary to rotate the take-up reel 116 in a direction opposite to the cover film take-up direction, the take-up reel 116 is rotated in a direction opposite to the cover film take-up direction, and the frictional force between the take-up reel 116 and the reel support member 164. May be applied to the take-up reel 116.

It is necessary in various cases to rotate the take-up reel 116 in the direction opposite to the cover film take-up direction. For example, when attaching while taking up the cover film 20 when attaching the take-up reel 116 to the support shaft 150, if it is not possible to rotate the cover film 20 in the opposite direction, the amount taken up for attachment can be returned. In other words, the electronic component 14 that has been covered by the wound cover film 20 cannot be returned to the component take-out position, resulting in waste. Therefore, it is necessary to rotate the take-up reel 116 in a direction opposite to the cover film take-up direction, rewind the cover film, and return the electronic component 16 to the component take-out position to eliminate waste. In addition, if the take-up reel 116 cannot be rotated in the reverse direction, it is difficult to attach and remove the take-up reel 116.
[0051]
The take-up reel 116 is frictionally engaged with the reel support member 164, and the rotation of the reel support member 164 in the direction opposite to the cover film take-up direction is prevented by the second one-way clutch 162. By applying a relative rotation torque exceeding the frictional force between the reel support member 164 and the reel support member 164, the take-up reel 116 can be rotated in the direction opposite to the cover film winding direction, The electronic component 16 is not wasted when the take-up reel 116 is mounted, and the workability when mounting and removing is improved. The operation of rotating the take-up reel 116 in a direction opposite to the cover film take-up direction may be performed by an operator or may be performed automatically.

As is clear from the above description, in the present embodiment, the case 33 constitutes a taped electronic component container, the mounting body 34 provided on the cartridge body 50 constitutes a holding device, and the drive lever 86 drives It constitutes a member. The sprocket 58, the ratchet wheel 62, the rotating plate 64 and the tape driving plate 82 constitute a feeding mechanism, and together with the driving lever 86 and the driving lever rotating device 200 constitute a taped electronic component feeding device. Further, the spring 94 constitutes an urging means, and the projection 112 constitutes a stopper.
[0053]
In the above embodiment, the drive lever is rotatable around one axis, but may be linearly moved.
[0054]
Further, the drive lever moving device for moving the drive lever is not limited to the device in which the engagement member is rotated, but may be a device in which the engagement member is linearly moved to rotate or linearly move the drive lever.
[0055]
Further, in the above-described embodiment, the tape-formed electronic component 16 is sent by the rotation of the drive lever 86, and the take-up lever 152 is rotated so that the cover film 20 is taken up on the take-up reel 116. However, for example, as in the electronic component supply cartridge described in JP-B-2-53958, the take-up reel is rotated by a dedicated rotation drive device separate from the drive lever to take up the cover film. The present invention can also be applied to those that can be used.
[0056]
Further, in the above-described embodiment, provided between the reel support member and the take-up reel, the two are normally rotated integrally, but when a relative rotation torque of a predetermined magnitude or more is applied, The friction engagement device allowing relative rotation is constituted by an O-ring 168, and has the advantage of a simple structure and low cost. However, the friction member is in contact with one of the reel support member and the take-up reel, and the contact member is in contact with the other. As long as a frictional force is generated between the take-up reel and the reel support member, such as a member that is attached as possible and urges the friction member in the contact direction by an elastic member, any member can be adopted.
[0057]
Further, the friction engagement device is not limited to the reel support member, and may be provided on the take-up reel side, or may be provided on both.
[0058]
In the above-described embodiment, the component suction head 110 is provided on the index table, and the component supply cartridge 12 can be moved in a direction orthogonal to the feed direction of the taped electronic component 16. One of the supply cartridges is moved in a direction in which the component supply cartridges are arranged, and the other is moved in a direction intersecting the direction in which the component supply cartridges are arranged.PlaceThe component supply cartridge is immovably provided, and the component mounting head is provided so that the component suction head can be moved to an arbitrary position in one plane.In placeThe present invention can also be applied to the present invention.
[0059]
In addition, without departing from the scope of the claims, various modifications and improvements can be made to the present invention based on the knowledge of those skilled in the art.
