Description

The present invention relates to a cover tape cutting device that cuts a cover tape that is peeled off from a carrier tape having a parts storage portion for storing parts and is discharged, a parts supply device and a parts mounting device provided with the cover tape cutting device.

Conventionally, a component mounting device has a configuration in which components supplied by a component supply device are picked up by a mounting head and mounted on a board. As the parts supply device, a tape feeder that conveys a carrier tape containing parts and supplies the parts to a predetermined part take-out position is often used. The carrier tape used in the tape feeder consists of a base tape on which a parts storage part for storing parts is formed and a cover tape that is attached to the base tape and encloses the parts in the parts storage part. It is peeled off from the base tape before reaching the part removal position.

The cover tape peeled off from the base tape is sent to a collection chamber provided in the tape feeder for collection, and is pulled out by an operator for disposal. When the operator collects the cover tape, if the carrier tape is still in use in the tape feeder, one end of the cover tape will be stuck to the base tape, so the operator will have to cut the cover tape. Must be pulled out of the collection room. In Patent Document 1 below, a tape feeder capable of cutting a cover tape pulled out from a collection chamber by pressing it from below against a cutter provided in the vicinity of the opening of the collection chamber at the upper part of the collection chamber. It is shown. Patent Document 2 discloses a tape feeder that cuts a cover tape collected in a collection chamber by sandwiching it between a fixed blade and a movable blade.

In this reciprocating movement, the mounting head 15 picks up the component BH supplied by the tape feeder 14 by the nozzle 15N and mounts it at a predetermined position on the substrate KB.

As described above, in the first embodiment, the mounting head 15 is a component mounting portion for taking out the component BH supplied by the tape feeder 14 which is a component supply unit and mounting the component BH on the substrate KB. When the mounting head 15 mounts all the component BHs to be mounted on the board KB, the board transport unit 12 operates to carry the board KB out of the component mounting device 1.

While the component mounting device 1 is operating as described above, each tape feeder 14 extends the cover tape 24 peeled off at the cover tape peeling portion 36 rearward from the cover tape peeling portion 36 (FIG. FIG. 5) Discharge within. The discharge passage 37 is connected to a collection chamber 38 provided at the rear of the tape feeder 14, and the cover tape 24 discharged to the discharge passage 37 by the cover tape peeling portion 36 is sent to the collection chamber 38 and collected.

In FIG. 4, a door 39 is provided at the rear of the tape feeder 14. The door 39 is rotatable around the vertical axis and opens and closes the rear opening of the collection chamber 38. Therefore, the worker OP can take out the cover tape 24 sent to the collection chamber 38 and dispose of it by opening the door 39.

In FIGS. 4 and 5, a cover tape cutting device 40 is provided at a position slightly rear of the cover tape peeling portion 36 inside the tape feeder 14. The cover tape cutting device 40 is a device that cuts the cover tape 24 that has been peeled off by the cover tape peeling portion 36 and discharged into the discharge path 37. The operator OP cuts the cover tape 24 and separates the cover tape 24 from the carrier tape 22 (base tape 23) before pulling out the cover tape 24 from the collection chamber 38, so that the cover tape from the collection chamber 38 is separated. The recovery of 24 can be facilitated. The present embodiment is characterized by the configuration of the cover tape cutting device 40, which will be described below.

In FIGS. 5, 6 and 7, the cover tape cutting device 40 includes a guide member 41, a clamp portion 42, a cutter unit 43, and a cutter operating portion 44. The guide member 41 is composed of a member that constitutes a part of the upper part of the tape feeder 14, and is a guide space 41S that is open downward and a guide portion side that extends in the vertical direction and communicates with the guide space 41S. It is provided with a rod insertion hole 41H.

In FIGS. 6 and 7, the clamp portion 42 has two clamp members (fixed side) arranged so as to face the positions where the cover tape 24 discharged to the discharge path 37 is sandwiched in the thickness direction (here, the vertical direction). It is equipped with a clamper 51 and a movable side clamper 52). The fixed side clamper 51 is located below the discharge path 37 which is the discharge path of the cover tape 24, and the movable side clamper 52 is located above the discharge path 37. The upper surface 51S (FIG. 7) extending in the lateral direction (Y-axis direction) of the fixed side clamper 51 forms a part of the discharge path 37 of the cover tape 24.

In FIGS. 6 and 7, the movable clamper 52 has a horizontally elongated portion 52Y extending in the lateral direction (Y-axis direction) and two pressing portions 52T extending downward from both ends of the horizontally elongated portion 52Y. The two pressing portions 52T fix the cover tape 24 at two locations (FIG. 7), an upstream position PJ and a downstream position PK along the discharge path (discharge path 37) of the cover tape 24, by the respective lower end surfaces 52S. This is the part that is pressed against the side clamper 51. A movable member-side rod insertion hole 52H extending in the vertical direction is provided in the central portion of the horizontally long portion 52Y.

The movable side clamper 52 is guided by the guide member 41 so that it can move in the guide space 41S of the guide member 41 in the forward direction toward the fixed side clamper 51 and in the backward direction away from the fixed side clamper 51. ing. As described above, in the present embodiment, the guide member 41 is located at a position facing the fixed side clamper 51 with the movable side clamper 52 interposed therebetween, and the movable side clamper 52 moves with respect to the fixed side clamper 51 (movement in the forward direction). And movement in the backward direction) is to guide.

In FIGS. 6 and 7, the cutter unit 43 includes a cutter base 61 and a cutter 62. The cutter base 61 is made of a member having a shape extending in the Y-axis direction, and is provided between two pressing portions 52T included in the movable side clamper 52. The base of the cutter 62 is attached to the cutter base 61, and the cutting edge 62K is directed downward. As described above, in the present embodiment, the cutter base 61 is a cutter holding portion for holding the cutter 62. The cutter unit 43 (that is, the cutter 62) moves between the two pressing portions 52T included in the movable clamper 52 in the forward direction toward the fixed clamper 51 and in the backward direction away from the fixed clamper 51. Is possible.

The cutter operation unit 44 is a member for pressing the cutter 62 against the cover tape 24, and is made of a rod-shaped member here. One end (lower end) side of the cutter operation portion 44 is connected to the cutter base 61, and penetrates the movable side clamper 52 (movable member side rod insertion hole 52H) and the guide member 41 (guide portion side rod insertion hole 41H) upward. The other end (upper end) side protrudes upward from the guide member 41.

In FIGS. 6 and 7, between the guide member 41 and the movable clamper 52, a first as a first attracting means that exerts a first attracting force that attracts the movable clamper 52 to the guide member 41. A magnet M1 and a second magnet M2 are provided. Further, between the movable clamper 52 and the cutter 62 (cutter unit 43), a third magnet M3 as a second attracting means that exerts a second attracting force that attracts the cutter 62 to the movable clamper 52. And a fourth magnet M4 is provided.

In FIGS. 6 and 7, the first magnet M1 is provided inside the guide member 41, and the lower surface is exposed to the outside. The second magnet M2 is provided at a position facing the first magnet M1 in the movable side clamper 52. The second magnet M2 exposes the polar side attracting the first magnet M1 from the upper surface of the horizontally long portion 52Y of the movable side clamper 52. Therefore, the movable side clamper 52 is attracted to the guide member 41 by the attractive force (first attractive force) between the first magnet M1 and the second magnet M2, and the cutter operation unit 44 is not operated. In the state (non-operated state), the upper surface of the horizontally elongated portion 52Y comes into contact with the guide member 41 from below (FIG. 6).

In FIGS. 6 and 7, the third magnet M3 is provided in the movable side clamper 52, and the lower surface is exposed to the outside. The fourth magnet M4 is provided at a position in the cutter base 61 facing the third magnet M3. The fourth magnet M4 exposes the polar side attracting the third magnet M3 from the upper surface. Therefore, the cutter 6262 (cutter unit 43) is attracted to the movable side clamper 52 by the attractive force (second attractive force) between the third magnet M3 and the fourth magnet M4, and the cutter operation unit 44 is moved. In the non-operated state, the upper surface is in contact with the lower surface of the horizontally long portion 52Y of the movable side clamper 52 (FIG. 6).

The magnetic properties of the first magnet M1, the second magnet M2, the third magnet M3, and the fourth magnet M4 are the attractive force between the third magnet M3 and the fourth magnet M4 (that is, the second magnet M4). The attractive force) is set to be larger than the attractive force (that is, the first attractive force) between the first magnet M1 and the second magnet M2. Therefore, when the cutter operation unit 44 is pressed downward from the non-operated state in which the cutter operation unit 44 is not operated, the cutter unit 43 is moved downward before being separated from the movable side clamper 52. The clamper 52 is separated downward from the guide member 41. Therefore, when the cutter operating unit 44 in the non-operated state is operated and the cutter 62 moves in the forward direction, the movable clamper 52 first moves against the first attracting force by the first attracting means to cover the cover. The tape 24 is pressed against the fixed side clamper 51, and then the cutter 62 moves against the second pulling force by the second pulling means and operates to cut the cover tape 24.

More specifically, when the cutter operation unit 44 is not operated by the operator OP, the operator OP presses the upper end portion of the cutter operation unit 44 downward with the finger Fg (shown in FIG. 8A). Arrow P) First, the movable side clamper 52 moves in the forward direction (downward) against the attractive force (first attractive force) due to the magnetic force between the first magnet M1 and the second magnet M2. (Arrow Z1 shown in FIG. 8B). As a result, the movable side clamper 52 uses the lower end surface 52S of each of the two pressing portions 52T to apply the cover tape 24 to the cover tape 24 at two locations, the upstream side position PJ and the downstream side position PK along the discharge path 37. Clamp in the vertical direction (vertical direction) (FIG. 8 (b)).

After the clamp portion 42 clamps the cover tape 24, the cutter 62 then moves in the forward direction against the attractive force (second attractive force) due to the magnetic force between the third magnet M3 and the fourth magnet M4. It moves (arrow Z2 shown in FIG. 8C). As a result, the cutter 62 is pressed from above against the cover tape 24 between the upstream position PJ and the downstream position PK, and cuts the cover tape 24 (FIG. 8 (c)). When the cover tape 24 is cut, the cover tape 24 in the collection chamber 38 is separated from the base tape 23. Therefore, when the operator OP opens the rear door 39 of the tape feeder 14 and discards the cover tape 24 in the collection chamber 38, the worker OP can discard the cover tape 24 taken out from the collection chamber 38 as it is.

When the operator OP presses the cutter operation unit 44 downward, the operator OP releases the finger Fg from the cutter operation unit 44. When the operator OP releases the finger Fg from the cutter operation unit 44, the cutter unit 43 receives an attractive force (second attraction) between the third magnet M3 and the fourth magnet M4, which are the second attraction means. The movable side clamper 52 moves in the backward direction by the force), and the movable side clamper 52 moves in the backward direction by the attractive force (first attractive force) between the first magnet M1 and the second magnet M2 which is the first attractive means. Move to. Therefore, the movable side clamper 52 and the cutter unit 43 return to the original state (non-operating state) before the cutter operating unit 44 is pressed by the operator OP (FIG. 8A).

When the cutter 62 is pressed against the cover tape 24, the cutter base 61 comes into contact with the upper surface 51S of the fixed side clamper 51 so as to sandwich the cover tape 24 with the fixed side clamper 51 (FIG. 8 (c)). As a result, the cutter 62 cannot move further in the forward direction. At this time, the fixed side clamper 51 functions as a stopper that limits the movement of the cutter 62 in the forward direction. That is, in the present embodiment, the cutter 62 moves in the forward direction when the cover tape 24 is cut by the cutter base 61 as the cutter holding portion sandwiching the cover tape 24 and contacting the fixed side clamper 51. The range of movement is limited.

As shown in FIG. 8C, when the cover tape 24 is cut by the cutter 62, the cutting edge 62K of the cutter 62 is located below the upper surface 51S of the fixed side clamper 51, but FIGS. 5, 6 and FIGS. As shown in 7, the fixed side clamper 51 is provided with a relief groove 51M as a relief portion for avoiding interference with the cutter 62 that has moved in the forward direction, so that the cutting edge 62K of the cutter 62 is the fixed side clamper 51. Do not touch. That is, in the present embodiment, the cutter 62 is pressed against the cover tape 24 between the two locations (upstream position PJ and downstream position PK) where the relative displacement is regulated by clamping with the clamp portion 42 to cover the cover. A tension is generated in the tape 24, and the generated tension is used to cut the cover tape 24.

In such a configuration, the cutting edge 62K of the cutter 62 does not come into contact with anything other than the cover tape 24, and the force received by the cutter 62 is only the reaction force due to the tension acting on the cover tape 24. Therefore, as compared with the case where the cover tape 24 is cut by pressing the cutting edge 62K of the cutter 62 against the fixed side clamper 51, the load received by the cutting edge 62K of the cutter 62 is extremely small and is not easily deteriorated. Therefore, the cutter 62 has a long life, the frequency of replacement work can be reduced, and the work load and cost of the operator OP can be significantly reduced.

Further, since the cutter 62 is pressed against the cover tape 24 in a tensioned state to cut the cover tape 24, a tape member having a small thickness such as the cover tape 24 can be easily and surely cut. In the case of cutting by moving the two blade surfaces relative to each other like scissors, tension may not necessarily be applied to the cover tape 24, but since the thickness of the cover tape 24 is small, there is a gap between the two blades. It has to be extremely small in size, and it is difficult to manufacture such scissors at low cost.

In the first embodiment, the first magnet M1 and the second magnet M2 generate a first attractive force that attracts the movable side clamper 52 to the guide member 41, and the third magnet M3 and the fourth magnet A second attracting force is generated by M4 to attract the cutter unit 43 to the movable side clamper 52, and each magnet (first magnet M1, second magnet M2, third magnet M3 and fourth magnet) M4) is an example, and a layout and a number of magnets other than the first embodiment may be used as long as the first attractive force and the second attractive force can be generated.

(Embodiment 2)
Next, Embodiment 2 of the present invention will be described. FIG. 9 shows the configuration of the cover tape cutting device 40A according to the second embodiment. The same components as those used in the cover tape cutting device 40 in the first embodiment are designated by the same reference numerals as those used in the first embodiment. In the second embodiment, all the configurations other than the cover tape cutting device 40A are the same as those in the first embodiment.

The difference between the cover tape cutting device 40A in the second embodiment and the cover tape cutting device 40 in the first embodiment is that the first pulling force that pulls the movable side clamper 52 toward the guide member 41 is exerted. It is composed of means and a second pulling means that exerts a second pulling force that pulls the cutter 62 (directly, the cutter base 61) to the movable side clamper 52. In the second embodiment, the first pulling means and the second pulling means are each composed of a tension spring (first spring S1 and second spring S2) as an elastic body.

Specifically, as shown in FIG. 9, the first spring S1 as the first pulling means has one end (upper end) side connected to the guide member 41 and the other end (lower end) side of the movable side clamper. It is connected to 52. Therefore, when the cutter operating unit 44 is not operated, the movable clamper 52 is pulled (upward) to the guide member 41 by the first spring S1 which is a tension spring. Further, in the second spring S2 as the second pulling means, one end (upper end) side is connected to the movable side clamper 52, and the other end (lower end) side is connected to the cutter base 61. Therefore, when the cutter operating unit 44 is not operated, the cutter 62 (cutter uni and 43) is pulled (upward) to the movable side clamper 52 by the second spring S2 which is a tension spring. There is.

The spring characteristics of the first spring S1 and the second spring S2 are such that the restoring force of the second spring S2 (that is, the second pulling force) is the restoring force of the first spring S1 (that is, the first pulling force). It is set to be larger than the pulling force). Therefore, when the cutter operation unit 44 is pressed downward from the non-operated state in which the cutter operation unit 44 is not operated, the cutter unit 43 is moved downward before being separated from the movable side clamper 52. The clamper 52 is separated downward from the guide member 41. Therefore, when the cutter operating unit 44 in the non-operated state is operated and the cutter 62 moves in the forward direction, the movable clamper 52 first pulls the first pulling force of the first pulling means (restoration of the first spring S1). The cover tape 24 is pressed against the fixed side clamper 51 by moving against the force), and then the cutter 62 resists the second attraction force of the second attraction means (the restoring force of the second spring S2). It operates to move and cut the cover tape 24.

More specifically, when the cutter operation unit 44 is not operated by the operator OP, the operator OP presses the upper end portion of the cutter operation unit 44 downward with the finger Fg (shown in FIG. 10A). Arrow P) First, the movable side clamper 52 moves in the forward direction against the restoring force (first attractive force) of the first spring S1 (arrow Z1 shown in FIG. 10B). As a result, the movable side clamper 52 covers the cover tape 24 at two positions along the discharge path 37, the upstream side position PJ and the downstream side position PK, by the lower end surface 52S (FIG. 9) of each of the two pressing portions 52T. Clamp in the thickness direction of the tape 24 (FIG. 10 (b)).

After the clamp portion 42 clamps the cover tape 24, the cutter 62 then moves in the forward direction against the restoring force (second pulling force) of the second spring S2 (shown in FIG. 10C). Arrow Z2). As a result, the cutter 62 is pressed from above against the cover tape 24 between the upstream position PJ and the downstream position PK, and cuts the cover tape 24 (FIG. 10 (c)). When the cover tape 24 is cut, the cover tape 24 in the collection chamber 38 is separated from the base tape 23. Therefore, when the operator OP opens the rear door 39 of the tape feeder 14 and discards the cover tape 24 of the collection chamber 38, the worker OP can discard the cover tape 24 taken out from the collection chamber 38 as it is.

When the operator OP presses the cutter operation unit 44 downward, the operator OP releases the finger Fg from the cutter operation unit 44. When the operator OP releases the finger Fg from the cutter operation unit 44, the cutter unit 43 moves in the backward direction by the restoring force (second pulling force) of the second spring S2 which is the second pulling means. The movable side clamper 52 moves in the backward direction by the restoring force (first attractive force) of the first spring S1 which is the first attractive means. Therefore, the movable side clamper 52 and the cutter unit 43 return to the original state (non-operating state) before the cutter operating portion 44 is pressed by the operator OP (FIG. 10A).

Also in the second embodiment, as in the case of the first embodiment, when the cutter 62 is pressed against the cover tape 24, the cutter base 61 is placed on the upper surface 51S of the fixed side clamper 51 so as to sandwich the cover tape 24 between them. Contact (FIG. 10 (c)). Further, as in the case of the first embodiment, the fixed side clamper 51 is provided with a relief groove 51M as a relief portion for avoiding interference with the cutter 62 that has moved in the forward direction, so that the cutting edge of the cutter 62 is provided. 62K does not come into contact with the fixed side clamper 51.

As described above, in the cover tape cutting devices 40 and 40A provided in the tape feeder 14 of the component mounting device 1 in the first and second embodiments, the carrier tape 22 discharged to the discharge path 37 is the discharge path. It is clamped by the clamp portion 42 at two locations along the upstream side position PJ and the downstream side position PK along 37, and the cutting edge 62K of the cutter 62 is pressed between the two clamped locations to cut. .. Since the cover tape 24 is clamped at two points by the clamp portion 42 and the cutter 62 is pressed in a state where tension is applied, it is not necessary for the operator OP to pull out from the collection chamber 38 of the tape feeder 14 and pull it at the time of cutting. .. Therefore, the cover tape 24 can be easily cut without being pulled out from the collection chamber 38 of the tape feeder 14 and without pulling the cover tape 24 by hand.

Further, since the cutter 62 is pressed against the cover tape 24 in a tensioned state for cutting, a tape member having a small thickness such as the cover tape 24 can be easily and surely cut. Further, since the cutter 62 only comes into contact with the cover tape 24 and receives a reaction force due to the tension acting on the cover tape 24, it is less likely to deteriorate and has a long life.

Further, in the cover tape cutting devices 40 and 40A provided in the tape feeder 14 of the component mounting device 1 in the present embodiment, the cutter operation unit 44 is connected to the cutter 62, and further, between the cutter 62 and the movable side clamper 52. The movable side clamper 52 and the guide member 41 are connected by a magnetic force or an attractive force due to the restoring force of the elastic body, and the operator OP presses the cutter operation unit 44 (one operation). The cover tape 24 can be clamped and cut only by performing an action), and the work of cutting the cover tape 24 by the operator OP becomes easy.

Although the embodiments of the present invention have been described so far, the present invention is not limited to those described above, and various modifications and the like are possible. For example, in the first embodiment described above, both the first attracting means and the second attracting means are made of magnets, and in the second embodiment, both the first attracting means and the second attracting means are both. Although it was made of a spring, one of the first pulling means and the second pulling means may be made of a magnet and the other may be made of a spring. Further, if the first pulling means pulls the movable side clamper 52 toward the guide member 41 and the second pulling means pulls the cutter 62 toward the movable side clamper 52 material. , The first attracting means and the second attracting means do not have to be magnets or springs.

Further, in the above-described first and second embodiments, the fixed side clamper 51 and the movable side clamper 52 are arranged so as to face each other vertically, but this is an example and is not necessarily arranged so as to face each other vertically. You may. Further, the vertical position of the fixed side clamper 51 and the movable side clamper 52 may be opposite to each other, and the cover tape 24 may be cut by moving the cutter 62 in the forward direction from the lower side to the upper side.

Further, in the above-described first and second embodiments, the cutter operation unit 44 that presses the cutter 62 against the cover tape 24 is pressed by the operator OP with a finger to perform a linear operation, but this is an example. , It may be operated by another method. For example, the piston rod of the cylinder may be used as the cutter operating unit 44, or the cutter operating unit 44 may be operated via a separately provided link mechanism, wire, or the like. Alternatively, the cutter operation unit 44 may be operated by electric force using an electric actuator such as a motor. Further, the main body that operates the cutter operation unit 44 may be a separately provided robot or the like in addition to the operator OP.

Further, in the above-described first and second embodiments, the tape feeder 14 is said to be an autoload type, but it does not necessarily have to be an autoload type, and a manual load type (a worker OP manually attaches the carrier tape 22). It may be a type that is loaded on the tape feeder 14.

Provided are a cover tape cutting device, a component supply device, and a component mounting device that can easily and reliably cut the cover tape without pulling it by hand.
