Description

  The present invention relates to a method of automatically peeling a cover tape from a subsequent carrier tape introduced next to a preceding carrier tape by a tape feeder that supplies components to a pickup position of a component mounting machine, and the automatic The present invention relates to a tape feeder that can realize peeling.

  2. Description of the Related Art In a component mounter that mounts components on a board, a tape feeder is known as one of devices that supply components to a pickup position where the component mounter holds the components. This tape feeder is a device that sequentially feeds components to the pick-up position of a component mounting machine by intermittently transferring (pitch feeding) a long belt-like carrier tape in which components are accommodated in each of the recessed portions arranged in a row. It is. The component mounter picks up the component supplied by the tape feeder by a transfer head having a plurality of nozzles that can hold the component by vacuum suction or the like.

  By the way, the carrier tape is composed of a long strip-shaped base tape in which concave portions for accommodating components are arranged in a row and a long strip-shaped cover tape for sealing the concave portions for accommodating the components, The tape feeder includes a mechanism that peels the cover tape from the base tape and exposes a recess in which a component is accommodated, upstream of the pickup position in the carrier tape transfer direction.

  For example, Patent Document 1 describes a tape feeder provided with a peeling blade for partially peeling a cover tape from a carrier tape in the width direction of the carrier tape in the vicinity of the pickup position.

  In this way, if the cover tape can be automatically peeled off from the subsequent carrier tape introduced into the tape feeder as the succeeding carrier tape using the peeling blade, the leading edge of the succeeding carrier tape is placed at the trailing edge of the preceding carrier tape. The so-called splicing work of pasting the tape in the butted state can be omitted, and the work of replenishing the carrier tape to the tape feeder can be performed.

JP 2011-2111169 A

  When introducing the following carrier tape into the tape feeder without splicing work, the tip of the peeling blade is brought into contact with the tip of the carrier tape, and the peeling blade is bitten between the base tape and the cover tape in the stuck state. Thus, an initial process is required in which the tape feeder autonomously automatically peels the tip of the cover tape from the base tape. However, in the initial process, there may be a problem that the cover tape cannot be peeled from the base tape.

  Therefore, the inventor of the present application, as a result of repeated experiments and research on the initial process, the cover tape is not peeled when the rear end of the preceding carrier tape remaining in the tape feeder interferes with the peeling blade. It came to find out that a malfunction is easy to occur.

  The present invention was made on the basis of the new knowledge found by the inventor, and in the initial step of peeling the tip of the cover tape from the base tape, a cover that can suppress the occurrence of a problem that the cover tape is not peeled from the base tape. An object is to provide a tape peeling method and a tape feeder.

  In order to achieve the above object, a cover tape peeling method according to the present invention transfers a carrier tape consisting of a base tape having a recess for housing a component and a cover tape for sealing the recess in the forward direction of the transfer direction. The component is moved toward a component supply position where the component is taken out from the carrier tape while peeling the cover tape from the base tape by a peeling blade provided at a position inserted between the base tape and the cover tape. In the tape feeder to be sequentially supplied, among the plurality of carrier tapes that are sequentially sent in the forward direction by the tape feeder, the forward direction toward the component supply position follows the preceding carrier tape that is sent in advance. A cover tape peeling method for introducing the subsequent carrier tape to be sent to An engagement step of engaging the subsequent carrier tape with a sprocket that is upstream of the peeling blade in the forward direction of the transfer direction for transferring the tape and that positions the concave portion of the carrier tape in the transfer direction; By driving the sprocket forward in the forward direction and transporting the subsequent carrier tape in the forward direction, the end of the preceding carrier tape already attached to the tape feeder and the leading end of the subsequent carrier tape are moved. An extruding step of abutting and pushing the end of the preceding carrier tape to the downstream side in the forward direction from the cutting edge of the peeling blade; and driving the sprocket in the reverse direction opposite to the forward direction to drive the succeeding carrier The succeeding carrier tape is continued until the tip of the tape is located upstream of the edge of the peeling blade in the forward direction. After the reverse flow step and the reverse flow step, the sprocket is driven forward in the forward direction to transfer the subsequent carrier tape again in the forward direction, and the cover tape is removed by the peeling blade. And a re-transfer process for peeling from the base tape.

  According to this, it is possible to push the preceding carrier tape that interferes with the peeling blade to a position where it does not interfere with the peeling blade by simply controlling the forward drive and reverse drive of the sprocket arranged upstream in the forward direction from the peeling blade. Can do. Therefore, after the tip of the carrier tape is transferred to the upstream side in the forward direction with respect to the peeling blade, when the carrier tape is re-transferred in the forward direction, the cutting edge of the peeling blade is accurately cut between the base tape and the cover tape. Therefore, it is possible to suppress as much as possible the occurrence of a problem that the cover tape cannot be peeled off in the initial step.

  In addition, when the error information indicating that the component cannot be removed from the subsequent carrier tape is received from the component mounter to which the tape feeder is attached after the retransfer step, the backflow step and the retransfer step are performed again. May be carried out.

  According to this, without overlooking the phenomenon that the cover tape is not peeled off, the peeling operation of the tip of the cover tape in the initial process can be performed again, and the operation of the component mounting machine can be maintained without relying on human hands. It becomes possible.

  In order to achieve the above object, a tape feeder according to the present invention transports a carrier tape comprising a base tape having a recess for housing a component and a cover tape for sealing the recess in the forward direction of the transport direction. And a peeling blade that is inserted between the base tape and the cover tape, toward the component supply position where the component is taken out from the carrier tape while peeling the cover tape from the base tape by the peeling blade. Among the plurality of carrier tapes that are sequentially supplied in the forward direction and are sequentially sent in the forward direction, and the subsequent tapes that are sent in the forward direction toward the component supply position after the preceding carrier tape that is sent in advance. A tape feeder for introducing a carrier tape, wherein the carrier tape is transferred in the forward direction of the transfer direction. It is already attached to the tape feeder by transferring the carrier tape, which is upstream of the separating blade, for transferring and positioning the carrier tape and the subsequent carrier tape introduced to the tape feeder in the forward direction. The end of the preceding carrier tape and the tip of the subsequent carrier tape are brought into contact with each other, and the end of the preceding carrier tape is pushed downstream in the forward direction from the cutting edge of the peeling blade. The extrusion control unit to control, and the sprocket so as to perform a reverse flow operation of transporting the subsequent carrier tape in the reverse direction until the tip of the subsequent carrier tape is positioned upstream in the forward direction from the cutting edge of the peeling blade. A reverse flow control unit for controlling the reverse flow, and after the reverse flow operation, the subsequent carrier tape is moved forward again. And sending, characterized in that it comprises a re-transfer control unit for controlling the sprocket so as to peel off the cover tape by the peeling blade.

  According to this, since the tape feeder autonomously controls the drive of the sprocket arranged upstream in the forward direction with respect to the peeling blade, the peeling can be done without burdening the software processing of the component mounting machine. The preceding carrier tape that interferes with the blade can be extruded, the subsequent carrier tape can be transferred in the reverse direction, and the carrier tape can be transferred again in the forward direction. Therefore, it is possible to suppress as much as possible the occurrence of problems that the cover tape cannot be peeled off in the initial process.

  Further, based on the error information indicating that the component cannot be taken out from the subsequent carrier tape received from the component mounter to which the tape feeder is attached, the retry control unit and the re-transfer control unit function again. It does not matter if it has a part.

  According to this, just by receiving an error message from the component mounting machine, the tape feeder that has transferred the component held on the subsequent carrier tape to the pickup position autonomously performs a retry operation to peel off the tip of the cover tape. Therefore, it is possible to maintain the operation of the component mounter without overlooking the phenomenon that the cover tape is not peeled off and without relying on human hands.

  In addition, implementing the program for making a computer perform each process which the said cover tape peeling method includes also corresponds to implementation of this invention. Of course, implementing the recording medium in which the program is recorded also corresponds to the implementation of the present invention.

  According to the present invention, the cover tape can be automatically peeled off with a high probability simply by inserting the subsequent carrier tape into the tape feeder, so even a beginner can easily replenish the carrier tape with the tape feeder, In addition, it is possible to reduce the number of people who monitor and operate the component mounting machine.

  FIG. 5 is a perspective view schematically showing the vicinity of the peeling blade of the tape feeder with the cover tape omitted.

  FIG. 6 is a side view schematically showing the vicinity of the peeling blade of the tape feeder.

  As shown in these drawings, the peeling blade 210 is located downstream of the sprocket 206 in the forward direction (Y-axis direction) in the forward direction (Y-axis direction positive side) and upstream in the forward direction (Y-axis direction negative). It is a mechanism portion that is inserted between the base tape 304 and the cover tape 307 relatively toward the side of the tape and peels the cover tape 307 from the base tape 304 by the force that the tape feeder 200 transports the carrier tape 300. The peeling blade 210 is attached to the main body 201 via the bracket 208 on the main body 201 of the tape feeder 200. The peeling blade 210 is attached so as to be disposed between the base tape 304 and the cover tape 307 of the carrier tape 300 that is transported while sliding on the tape running path 204 of the main body 201, and the cover tape 307 of the base tape 304 is attached. It is arranged in a state slightly separated from the lower surface of the tape running path 204 on the surface side opposite to the surface to be attached. Further, the peeling blade 210 is urged by a urging member 281 toward the lower surface side of the tape traveling path 204 and is movably attached in a direction away from the tape traveling path 204.

The first guide body 213 and the second guide body 214 function as a guide member that forms a transfer path of the peeled cover tape 307, and a base in which components are stored by the transfer of the base tape 304 is provided. This is a portion that guides the cover tape downstream of the peeling blade 210 in the forward direction of the transfer direction while exposing the concave portion 305 of the tape 304.

  FIG. 7 is a block diagram showing details of a functional unit of the feeder control unit together with a mechanism unit and the like.

  As shown in the figure, the components are sequentially supplied toward the pickup position P where the components are taken out from the carrier tape 300, and the plurality of carrier tapes 300 that are sequentially sent in the transfer direction of the carrier tape 300 are sent in advance. In the tape feeder 200 that introduces the succeeding carrier tape 311 that is sent in the forward direction toward the pickup position P after the preceding carrier tape 312, the feeder control unit 209 of the tape feeder 200 includes an extrusion control unit 291 and a backflow control. Unit 292 and a re-transfer control unit 293. In the present embodiment, the feeder control unit 209 includes an information communication unit 294 and a retry unit 295.

  As shown in FIG. 8, the extrusion control unit 291 moves the subsequent carrier tape 311 that is the subsequent carrier tape 300 introduced into the tape feeder 200 in the forward direction (positive direction in the Y-axis direction in the drawing), The end of the preceding carrier tape 312 which is the preceding carrier tape 300 already attached to the tape feeder 200 is brought into contact with the tip of the succeeding carrier tape 311 and the end of the preceding carrier tape 312 is peeled off as shown in FIG. It is a processing unit that controls the rotation of the sprocket 206 so as to push the blade 210 toward the downstream side in the forward direction (the positive side in the Y-axis direction) with respect to the blade edge (the blade edge body 211).

  Specifically, the extrusion control unit 291 recognizes the position of the leading end of the introduced subsequent carrier tape 311 based on a signal from the sensor 220 disposed in the tape traveling path 204 and transfers the subsequent carrier tape 311 to the sprocket 206. The position of the tip of the subsequent carrier tape 311 is accurately controlled from the sprocket 261 (see FIG. 2), the amount of rotation of the sprocket 206, and the like.

  The backflow control unit 292 acquires information indicating that the extrusion control unit 291 has transferred the subsequent carrier tape 311 in the forward direction of a predetermined length, and the tip of the subsequent carrier tape 311 is in the forward direction with respect to the cutting edge of the peeling blade 210. It is a processing unit that controls the sprocket 206 so as to transport the subsequent carrier tape 311 in the reverse direction until it is located upstream (Y-axis direction negative side).

  The retransfer control unit 293 acquires information indicating that the backflow control unit 292 has transferred the subsequent carrier tape 311 in the reverse direction by a predetermined length, and transfers the subsequent carrier tape 311 in the forward direction as shown in FIG. The processing unit controls the sprocket 206 so that the cover tape 307 is peeled off by the peeling blade 210.

  As described above, when the leading carrier tape 312 interferes with the peeling blade 210, for example, when the leading edge of the trailing carrier tape 311 sinks below the rear end of the leading carrier tape 312, the peeling blade 210 is slightly lifted. When the peeling blade 210 is slightly lifted by wrinkles generated in the preceding carrier tape 312 pushed out by the subsequent carrier tape 311, the cutting edge of the peeling blade 210 is located between the base tape 304 of the subsequent carrier tape 311 and the cover tape 307. It is possible to avoid the problem that the cover tape 307 cannot be peeled off by the peeling blade 210 without being inserted.

  The information communication unit 294 is a processing unit that transmits and receives various types of information from the component mounting machine 100 via the connector 203.

  When the information communication unit 294 receives error information indicating that the component 302 cannot be removed from the subsequent carrier tape 311, the retry unit 295 causes the reverse flow control unit 292 and the retransfer control unit 293 to function, and the subsequent carrier tape After the component 302 held by 311 is transferred to the pickup position P, the tip of the subsequent carrier tape 311 is moved in the reverse direction until it is positioned upstream of the cutting edge of the peeling blade 210 in the forward direction in the transfer direction (see FIG. 10). It is a processing unit that transports and again peels the cover tape 307 by transporting the subsequent carrier tape 311 in the forward direction again.

  According to the above, the carrier tape 300 including the base tape 304 having the recess 305 for housing the components and the cover tape 307 for sealing the recess 305 is transferred in the forward direction of the transfer direction, and the base tape 304 and the cover tape are also transferred. A separation blade 210 inserted between the component tape 307 and the separation blade 210, while peeling the cover tape 307 from the base tape 304 by the separation blade 210, sequentially supplying the components toward the component supply position P where the components are taken out from the carrier tape 300, Of the plurality of carrier tapes 300 that are sequentially sent in the forward direction, the tape feeder 200 that introduces the subsequent carrier tape 311 that is sent in the forward direction toward the component supply position P after the preceding carrier tape 312 that is sent in advance. Is peeled off in the forward direction of the transfer direction for transferring the carrier tape 300. The sprocket 206, which is upstream of the blade 210 and performs the transfer and positioning of the carrier tape 300, and the subsequent carrier tape 311 introduced into the tape feeder 200 are transferred in the forward direction and are already attached to the tape feeder 200. Extrusion for controlling the sprocket 206 so that the end of the preceding carrier tape 312 and the end of the subsequent carrier tape 311 are brought into contact with each other and the end of the preceding carrier tape 312 is pushed downstream in the forward direction from the cutting edge of the peeling blade 210. Back flow that controls the sprocket 206 so as to perform a back flow operation in which the control unit 291 and the subsequent carrier tape 311 are transported in the reverse direction until the tip of the subsequent carrier tape 311 is positioned upstream of the cutting edge of the peeling blade 210 in the forward direction. After the controller 292 and the backflow operation, the subsequent key The subsequent carrier which is the carrier tape 300 by the peeling blade 210 is provided with a re-transfer control unit 293 that controls the sprocket 206 so that the rear tape 311 is transferred again in the forward direction and the cover tape 307 is peeled off by the peeling blade 210. The problem that the cover tape 307 of the tape 311 cannot be peeled can be suppressed as much as possible.

  Next, the cover tape peeling method will be described.

  FIG. 12 is a flowchart showing the flow of the cover tape peeling method.

  The components are sequentially supplied from the carrier tape 300 toward the pickup position P where the components are picked up, and among the plurality of carrier tapes 300 that are sequentially sent in the transfer direction of the carrier tape 300, the subsequent carrier tape 312 is followed by the preceding carrier tape 312. In the tape feeder 200 that introduces the subsequent carrier tape 311 that is fed in the forward direction toward the pickup position P, the component mounting machine 100 first introduces the subsequent carrier tape 311 among the plurality of tape feeders 200 that are attached. Is identified, and information specifying the carrier tape 300 that holds the type of the corresponding component 302 is notified (S101: notification step).

  The worker who has recognized the information introduces the corresponding subsequent carrier tape 311 into the corresponding tape feeder 200 (S102: introduction step). Specifically, the transfer hole 306 of the subsequent carrier tape 311 is engaged with the auxiliary sprocket 261.

  When the subsequent carrier tape 311 is introduced, the tape feeder 200 drives the auxiliary sprocket 261 and transfers the subsequent carrier tape 311 until reaching the sprocket 206 that positions the carrier tape 300 in the transfer direction with respect to the pickup position P. Then, the pin of the sprocket 206 is engaged with the transfer hole 306 of the subsequent carrier tape 311 (S103: engagement step).

  Next, the extrusion controller 291 of the tape feeder 200 drives the sprocket 206 to rotate forward in the forward direction and transports the subsequent carrier tape 311 in the forward direction by a predetermined length. As a result, the end of the preceding carrier tape 312 already attached to the tape feeder 200 and the tip of the succeeding carrier tape 311 come into contact with each other, and the end of the preceding carrier tape 312 is more downstream in the forward direction than the cutting edge of the peeling blade 210. Extrude (S104: extrusion process).

  Next, the backflow control unit 292 drives the sprocket 206 in the reverse direction to the forward direction, and continues the subsequent carrier tape 311 until the tip of the subsequent carrier tape 311 is positioned upstream of the cutting edge of the peeling blade 210 in the forward direction. Are transferred in the reverse direction (S105: backflow process).

  By the extrusion process and the backflow process, interference with the peeling blade 210 by the preceding carrier tape 312 can be eliminated, and the distance between the peeling blade 210 and the tape running path 204 can be returned to a predetermined distance.

  After the backflow process, the re-transfer control unit 293 drives the sprocket 206 in the forward direction to transfer the subsequent carrier tape 311 in the forward direction, and peels the cover tape 307 from the base tape 304 by the peeling blade 210 (S106). : Re-transfer process).

  Based on the above, it becomes possible for the operator to automatically peel the cover tape 307 of the subsequent carrier tape 311 from the base tape 304 with high accuracy without performing complicated work such as splicing.

  Further, after the component 302 held on the subsequent carrier tape 311 is transferred to the pickup position P, it is determined whether error information is received from the component mounting machine 100 (S107: determination step), and error information is received. (S107: Y), the backflow process (S105) and the re-transfer process (S106) may be repeated (retry process).

  According to the above, the cover tape 307 can be automatically peeled from the subsequent carrier tape 311 with higher accuracy.

  In addition, this invention is not limited to the said embodiment. For example, another embodiment realized by arbitrarily combining the components described in this specification and excluding some of the components may be used as an embodiment of the present invention. In addition, the present invention includes modifications obtained by making various modifications conceivable by those skilled in the art without departing from the gist of the present invention, that is, the meaning described in the claims. It is.

  For example, the peeling blade 210 has been described as being attached by the bracket 208 via the biasing member 281, but is not limited to this configuration. For example, the peeling blade 210 may be fixedly attached to the main body 201 so as to be elastically deformable.

  The tape feeder 200 has a plate-like shape that covers the upper side of the base tape 304 on the downstream side in the forward direction of the peeling blade 210 and has a through hole corresponding to the recess 305 of the base tape 304 at the pickup position P. An upper member may be provided. The upper member is a member that presses the base tape 304 guided by the main body 201 of the tape feeder 200 from above, and the base tape 304 can be stably transferred by the upper member.

  Moreover, although the embossed type was illustrated as the carrier tape 300, the carrier tape 300 is the same not only in an embossed type but in a paper tape type.

  The first guide body 213 and the second guide body 214 may be rollers, and the shape of the rollers is not only a cylinder but also a cylinder or a cone as long as it is a member that can be guided by pressing the cover tape 307. It doesn't matter.

  Further, in the re-transfer process, the entire width of the cover tape 307 in the width direction (X-axis direction in the figure) may be peeled off from the base tape 304 by the peeling blade 210.

  Further, as shown in FIG. 13, a guide member 283 that forms a transfer path of the cover tape 307 to which the peeled cover tape 307 is transferred is provided, and the cover tape 307 is raised from the base tape 304 (positive in the Z-axis direction). It is also possible to guide the cover tape 307 to the upstream side in the forward direction of the transfer direction (the negative side in the Y-axis direction) while suppressing the movement of the guide tape 307 (guide process).

  Further, in order to forcibly transfer the cover tape 307, a transfer roller 282 that rotates while sandwiching the cover tape 307 may be provided.

  The tape feeder and the cover tape peeling method of the present invention can be used for a component mounting machine in which components are supplied by a carrier tape. The component mounter is a device for mounting a component on a substrate such as a printed board, a flexible substrate, or a ceramic substrate, a device for mounting a component on a liquid crystal panel, or the like.
