The position of the sprocket 33 in the rotational direction is detected by detecting the position of the slit plate 35 in the rotational direction.
Further, the detection device 60 can detect the speed of the sprocket 33 in the rotational direction by detecting the amount of change per unit time in the position of the sprocket 33 in the rotational direction. Detection data of the detection device 60 indicating the position and speed in the rotational direction of the sprocket 33 is output to the control device 50.
The carrier tape 11 is conveyed in the conveying direction by the rotation of the sprocket 33. The speed of the sprocket 33 in the rotation direction is substantially equal to the speed of the carrier belt 11 in the conveyance direction. The control device 50 can detect the speed of the carrier tape 11 in the conveying direction based on the speed of the sprocket 33 in the rotating direction detected by the detection device 60.
The detection device 60 may detect the position and speed of the sprocket 34 in the rotational direction, or may detect the position and speed of both the sprocket 33 and the sprocket 34 in the rotational direction.

The optical sensor 80 can detect the end surface 11T of the carrier tape 11 in the conveying direction of the conveying mechanism 30.
Fig. 9 is a perspective view schematically showing an example of the optical sensor 80 according to the present embodiment. As shown in fig. 6 and 9, the optical sensor 80 includes: an emission unit 81 that emits detection light; and a light receiving unit 82 disposed at a position where at least a part of the detection light emitted from the emitting unit 81 can be received. The injection unit 81 is disposed on the-Z side of the carrier tape 11 conveyed by the conveying mechanism 30. The light receiving unit 82 is disposed on the + Z side of the carrier tape 11 conveyed by the conveying mechanism 30. The emission portion 81 and the light receiving portion 82 are supported by the main frame 20. As shown in fig. 6, in the present embodiment, the light receiving unit 82 is supported by the main frame 20 via the support member 83. The relative positions of the emission portion 81 and the light receiving portion 82 are fixed.

The emitting portion 81 may be disposed on the + Z side of the carrier tape 11, and the light receiving portion 82 may be disposed on the-Z side of the carrier tape 11.
The carrier tape 11 has an end surface 11T. The length of the carrier tape 11 wound around the reel 104 is limited. As shown in fig. 9, the carrier tape 11 is provided in the non-storage portion 15 to form an end surface 11T. The end surface 11T is provided on the downstream side in the conveying direction of the carrier tape 11. The end surface 11T of the carrier tape 11 includes an end 15T of the non-storage portion 15 in the conveying direction. The end surface 11T of the carrier tape 11 includes an end portion of the outer tape 13 disposed on the same plane as the end portion 15T of the non-storing portion 15 of the base tape 12.
The optical sensor 80 detects the position of the end surface 11T of the carrier tape 11 conveyed by the conveying mechanism 30. The conveying mechanism 30 conveys the carrier tape 11 so that the end surface 11T of the carrier tape 11 passes through the optical path of the detection light between the emitting portion 81 and the light receiving portion 82. The end surface 11T of the carrier tape 11 is moved by the conveying mechanism 30 from the upstream side in the conveying direction to the downstream side in the conveying direction with respect to the optical path of the detection light of the optical sensor 80. In the state where the detection light is emitted from the emitting portion 81, the light receiving state of the detection light by the light receiving portion 82 before the end surface 11T of the carrier tape 11 passes through the optical path of the detection light and the light receiving state of the detection light by the light receiving portion 82 after the end surface 11T of the carrier tape 11 passes through the optical path of the detection light are different. Before the end surface 11T of the carrier tape 11 passes through the optical path of the detection light, the carrier tape 11 is not present between the emitting portion 81 and the light receiving portion 82. The light receiving unit 82 receives the detection light emitted from the emitting unit 81 at the 1 st light receiving amount. After the end surface 11T of the carrier tape 11 passes through the optical path of the detection light, the carrier tape 11 is present between the emission portion 81 and the light receiving portion 82. At least a part of the detection light emitted from the emitting portion 81 is blocked by the belt 11, and the light receiving portion 82 receives the detection light emitted from the emitting portion 81 at the 2 nd light receiving amount smaller than the 1 st light receiving amount.

The control device 50 can detect the timing at which the end surface 11T of the carrier tape 11 passes through the optical path of the detection light based on the light receiving state of the detection light by the light receiving portion 82 of the optical sensor 80. The control device 50 can detect the position of the end surface 11T of the carrier tape 11 in the conveying direction of the conveying mechanism 30 based on the light receiving state of the detection light of the light receiving unit 82 of the optical sensor 80. The control device 50 determines that the light receiving amount of the detection light received by the light receiving unit 82 of the optical sensor 80 is changed from the 1 st light receiving amount to the 2 nd light receiving amount, and that the end surface 11T of the carrier tape 11 passes through the optical path of the detection light. When the light receiving amount of the detection light received by the light receiving unit 82 of the optical sensor 80 changes from the 1 st light receiving amount to the 2 nd light receiving amount, the control device 50 determines that the end surface 11T of the carrier tape 11 is positioned on the optical path of the detection light.
The speed of the carrier tape 11 conveyed to the conveying mechanism 30 is detected by the detecting device 60. The control device 50 can calculate the position of the end surface 11T of the carrier tape 11 in the conveying direction after the end surface 11T of the carrier tape 11 passes through the optical path of the detection light based on the position of the end surface 11T of the carrier tape 11 detected by the optical sensor 80 and the speed of the carrier tape 11 detected by the detection device 60.
In fig. 9, the size D of the non-storing section 15 in the conveying direction is known data. The dimension D is a distance in the conveying direction between an end 15T of the non-accommodating portion 15 defining the end surface 11T of the carrier tape 11 and a boundary 15U of the accommodating portion 14 adjacent to the non-accommodating portion 15. The end 15T defines an end of the non-storage portion 15 on the downstream side in the transport direction, and the boundary 15U defines an end of the non-storage portion 15 on the upstream side in the transport direction. The dimension D can be measured using a measuring jig or measuring device.
The control device 50 can calculate the timing at which the boundary 15U passes through the optical path of the detection light of the optical sensor 80, based on the position of the end surface 11T of the carrier tape 11 detected by the optical sensor 80, the speed of the carrier tape 11 detected by the detection device 60, and the size D of the non-storage portion 15, which is known data. The control device 50 can calculate the position in the conveying direction of the boundary 15U of the non-storage portion 15 after the boundary 15U of the non-storage portion 15 passes through the optical path of the detection light based on the position of the end surface 11T of the carrier tape 11, the speed of the carrier tape 11, and the size D of the non-storage portion 15.
Next, the peeling mechanism 40 will be explained. Fig. 10 is a perspective view schematically showing an example of the peeling mechanism 40 according to the present embodiment.

The guide member 43 is supported by the main frame 20. The carrier tape 11 is guided by the surface 44 of the guide member 43. The surface 44 comprises: an inclined surface 44A inclined in the + Z direction toward the + Y direction; and a flat surface 44B connected to an end of the inclined surface 44A on the downstream side in the conveying direction and parallel to the XY plane.
An opening 45 is formed in a part of the inclined surface 44A. The optical sensor 80 detects the end surface 11T of the carrier tape 11 passing over the opening 45. The injection portion 81 is disposed on the-Z side of the opening 45. The light receiving portion 82 is disposed on the + Z side of the opening 45. The light receiving unit 82 is supported by the main frame 20 via a support member 83. The light receiving unit 82 may be supported by the guide member 43 via the support member 83. The detection light emitted from the emitting portion 81 passes through the opening 45. The light receiving unit 82 is disposed at a position where the detection light emitted from the emitting unit 81 and passing through the opening 45 can be received.
The peeling member 41 is disposed downstream of the optical sensor 80 in the conveyance direction. As shown in fig. 5, 6, and the like, the peeling member 41 is disposed between the sprocket 33 and the sprocket 34 in the conveying direction. The supply position SM is defined on the downstream side in the conveyance direction of the peeling member 41.
The peeling member 41 has a leading end portion 41T facing the upstream side in the conveying direction. The tip portion 41T includes a blade edge of the peeling member 41. The peeling member 41 has a pointed tip portion 41T. The dimension of the peeling member 41 in the X-axis direction gradually becomes larger toward the downstream side in the conveying direction. Further, the dimension of the peeling member 41 in the Z-axis direction gradually increases toward the downstream side in the conveying direction. The size of the peeling member 41 in the X-axis direction indicates the width of the peeling member 41. The dimension of the peeling member 41 in the Z-axis direction indicates the thickness of the peeling member 41. The front end 41T of the peeling member 41 can enter between the base tape 12 and the outer tape 13.
The peeling member 41 is displaceable in the Z-axis direction. The peeling member 41 is not displaced in the Y-axis direction. By adjusting the position of the peeling member 41 in the Z-axis direction and moving the carrier tape 11 in the + Y direction by the conveying mechanism 30, the tip portion 41T of the peeling member 41 can enter between the base tape 12 and the outer tape 13 from the end surface 11T of the carrier tape 11. Further, the peeling member 41 may be displaced in the Y-axis direction.
The driving device 42 moves the peeling member 41 so that at least a part of the outer tape 13 is separated from the base tape 12 after the leading end portion 41T of the peeling member 41 enters between the base tape 12 and the outer tape 13. The driving device 42 includes, for example, an actuator such as a solenoid. The driving device 42 may include a piezoelectric element as an actuator.
After the leading end portion 41T of the peeling member 41 enters between the base tape 12 and the outer tape 13, the driving device 42 moves the peeling member 41 in the Z-axis direction intersecting the plane 44B and the lower surface of the base tape 12 opposite to the plane 44B, so that at least a part of the outer tape 13 is separated from the base tape 12. The driving device 42 moves the peeling member 41 in the Z-axis direction in a state where the lower surface of the outer tape 13 is in contact with the peeling member 41.

Although not shown in fig. 10, a part of the sprocket pin of the sprocket 33 and a part of the sprocket pin of the sprocket 34 are disposed in the opening 46. The sprocket 33 is disposed downstream of the peeling member 41 in the conveying direction. The sprocket 34 is disposed upstream of the peeling member 41 in the conveying direction. The supply position SM is defined between the sprocket 33 and the sprocket 34 on the downstream side in the conveyance direction from the peeling member 41.

Next, a method of supplying the electronic component C according to the present embodiment will be described. Fig. 12 is a flowchart showing an example of a method of supplying the electronic component C according to the present embodiment. Fig. 13 is a side sectional view schematically showing an example of the operation of the peeling mechanism 40 according to the present embodiment. Fig. 14 and 15 are plan views each schematically showing an example of the operation of the peeling mechanism 40 according to the present embodiment.
The reel 104 wound with the tape carrier 11 is loaded on the reel holder 103. The data specific to the carrier tape 11 is stored in the storage device 50B. As the data specific to the carrier tape 11, size data indicating at least the size D of the non-storage portion 15 is stored in the size data storage portion 56 of the storage device 50B. The size data acquisition unit 53 acquires the size data of the non-storage unit 15 from the size data storage unit 56 (step S10).
Further, distance data indicating the distance L between the optical path of the detection light of the optical sensor 80 in the conveying direction and the tip portion 41T of the peeling member 41 is stored in the distance data storage unit 57. The distance data obtaining unit 54 obtains the distance data from the distance data storage unit 57 (step S20).
The end surface 11T of the carrier tape 11 is fed to the tape feeder 10 through the inlet 21. The control section 55 outputs a control signal for conveying the carrier tape 11 to the motor drive device 70 so that the carrier tape 11 supplied to the tape feeder 10 via the inlet 21 is conveyed to the peeling mechanism 40 (step S30).
The motor drive device 70 drives the drive motor 37 based on the control signal. The sprocket 39 is rotated by the operation of the drive motor 37, and the end surface 11T of the carrier tape 11 is conveyed to the optical sensor 80.
The motor drive device 70 drives the drive motor 31 based on the control signal. By the operation of the drive motor 31, the sprocket 33 and the sprocket 34 rotate respectively.
The detection device 60 detects the rotational speed of the sprocket 39 and the rotational speed of the sprocket 33. The rotational speed of the sprocket 39 and the rotational speed of the sprocket 33 show the speed of the carrier tape 11 conveyed by the conveying mechanism 30. The speed data acquiring unit 52 acquires the speed data of the carrier tape 11 from the detecting device 60 (step S40).
The end surface 11T of the carrier tape 11 fed from the inlet 21 to the tape feeder 10 is conveyed to the optical sensor 80 by the rotation of the sprocket 39. The optical sensor 80 detects the position of the end surface 11T of the carrier tape 11.
Fig. 13(a) schematically shows a state in which the end surface 11T of the carrier tape 11 conveyed to the conveying mechanism 30 is disposed on the optical path of the detection light of the optical sensor 80. The conveying mechanism 30 conveys the carrier tape 11 so that the end surface 11T of the carrier tape 11 passes through the optical path of the detection light between the emitting unit 81 and the light receiving unit 82. The end surface 11T of the carrier tape 11 moves from the upstream side in the conveying direction to the downstream side in the conveying direction with respect to the optical path of the detection light of the optical sensor 80. The optical sensor 80 detects the position of the end surface 11T of the carrier tape 11 conveyed by the conveying mechanism 30. In the state where the detection light is emitted from the emitting portion 81, the light receiving state of the detection light by the light receiving portion 82 before the end surface 11T of the carrier tape 11 passes through the optical path of the detection light is different from the light receiving state of the detection light by the light receiving portion 82 after the end surface 11T of the carrier tape 11 passes through the optical path of the detection light. The detection data of the optical sensor 80 is output to the control device 50.
The position data acquisition unit 51 acquires the timing at which the end surface 11T of the carrier tape 11 passes through the optical path of the detection light of the optical sensor 80, based on the light receiving state of the detection light of the light receiving unit 82 of the optical sensor 80. The position data acquiring unit 51 acquires position data indicating the position of the end surface 11T of the carrier tape 11 in the conveying direction of the conveying mechanism 30 based on the light receiving state of the detection light by the light receiving unit 82 of the optical sensor 80 (step S50).
The control unit 55 calculates the position of the end surface 11T of the carrier tape 11 in the conveying direction after the end surface 11T of the carrier tape 11 passes through the optical path of the detection light of the optical sensor 80 based on the position data of the end surface 11T of the carrier tape 11 acquired by the position data acquiring unit 51 and the speed data of the carrier tape 11 acquired by the speed data acquiring unit 52.
The control unit 55 calculates the time at which the end surface 11T of the carrier tape 11 reaches the tip end portion 41T of the peeling member 41 after passing through the optical path of the detection light of the optical sensor 80, based on the position data of the end surface 11T of the carrier tape 11 acquired by the position data acquisition unit 51, the speed data of the carrier tape 11 acquired by the speed data acquisition unit 52, and the distance data between the optical path of the detection light of the optical sensor 80 and the tip end portion 41T of the peeling member 41 acquired by the distance data acquisition unit 54.
Fig. 13(B) schematically shows a state where the end surface 11T of the carrier tape 11 conveyed to the conveying mechanism 30 reaches the leading end portion 41T of the peeling member 41. The position of the peeling member 41 in the Z-axis direction is adjusted so that the leading end portion 41T of the peeling member 41 enters between the base tape 12 and the outer tape 13 of the carrier tape 11 conveyed by the conveying mechanism 30. The peeling member 41 is disposed downstream of the end surface 11T of the carrier tape 11 in the conveying direction. The leading end 41T of the peeling member 41 faces the upstream side in the conveying direction. Therefore, by conveying the carrier tape 11 to the downstream side in the conveying direction by the conveying mechanism 30, the leading end portion 41T of the peeling member 41 can enter between the base tape 12 and the outer tape 13.
In the following description, the position of the peeling member 41 in the Z-axis direction before the leading end portion 41T of the peeling member 41 enters between the base tape 12 and the outer tape 13 is referred to as an initial position as appropriate.
After the leading end portion 41T of the peeling member 41 enters between the base tape 12 and the outer tape 13 of the carrier tape 11 conveyed by the conveying mechanism 30, the control section 55 outputs a control signal for moving the peeling member 41 to the driving device 42 so that at least a part of the outer tape 13 is separated from the base tape 12 (step S60).
Fig. 13(C) schematically shows a state where the peeling member 41 which has entered between the base tape 12 and the outer tape 13 starts moving. As shown in fig. 13(C), the drive device 42 moves the peeling member 41 in the + Z direction so that at least a part of the cover tape 13 is separated from the base tape 12 in a state where the cover tape 13 and the peeling member 41 are in contact.
As described above, the control unit 55 can calculate the time when the end surface 11T of the carrier tape 11 reaches the tip end portion 41T of the peeling member 41 based on the position data of the end surface 11T of the carrier tape 11 acquired by the position data acquiring unit 51, the speed data of the carrier tape 11 acquired by the speed data acquiring unit 52, and the distance data acquired by the distance data acquiring unit 54. Therefore, the control section 55 can output a control signal for starting the movement of the peeling member 41 in the + Z direction to the driving device 42 after the leading end portion 41T of the peeling member 41 enters between the base tape 12 and the outer tape 13.
In the present embodiment, the driving device 42 starts the movement of the peeling member 41 after the leading end portion 41T of the peeling member 41 enters the end portion 15T of the non-storage portion 15 and before the leading end portion reaches the storage portion 14.
The control unit 55 calculates the position in the conveying direction of the boundary 15U between the non-storage portion 15 and the storage portion 14 after the end surface 11T of the carrier tape 11 passes through the optical path of the detection light of the optical sensor 80, based on the position data of the end surface 11T of the carrier tape 11 acquired by the position data acquisition unit 51, the speed data of the carrier tape 11 acquired by the speed data acquisition unit 52, and the size data of the non-storage portion 15 acquired by the size data acquisition unit 53.
Further, the control unit 55 calculates the timing at which the boundary 15U between the non-storage portion 15 and the storage portion 14 reaches the tip portion 41T of the peeling member 41 after the end surface 11T of the carrier tape 11 passes through the optical path of the detection light of the optical sensor 80 based on the position data of the end surface 11T of the carrier tape 11 acquired by the position data acquisition unit 51, the speed data of the carrier tape 11 acquired by the speed data acquisition unit 52, the size data of the non-storage portion 15 acquired by the size data acquisition unit 53, and the distance data acquired by the distance data acquisition unit 54. Thus, the control unit 55 can output a control signal for starting the movement of the peeling member 41 in the + Z direction to the driving device 42 after the front end portion 41T of the peeling member 41 enters between the base tape 12 and the outer tape 13 and before the front end portion 41T of the peeling member 41 reaches the accommodating portion 14 (boundary 15U).
In the present embodiment, the drive device 42 moves the peeling member 41 by a predetermined amount in the + Z direction from the initial position. The predetermined amount is, for example, 1[ mm ] or more and 3[ mm ] or less. In the following description, the position of the peeling member 41 in the Z-axis direction when moving from the initial position by a predetermined amount in the + Z direction is appropriately referred to as a predetermined position.
The driving device 42 stops the peeling member 41 at the predetermined position after moving the peeling member 41 from the initial position to the predetermined position. That is, the driving device 42 moves the peeling member 41 by a predetermined amount in the + Z direction from the initial position, and then maintains the position of the peeling member 41 in the Z axis direction at a predetermined position. The driving device 42 maintains the peeling member 41 at a predetermined position after moving the peeling member 41 in the + Z direction from the initial position so that the peeling member 41 continuously supports at least a part of the outer seal tape 13 during the conveyance of the carrier tape 11 by the conveying mechanism 30.
As shown in fig. 14, the peeling member 41 is disposed on the-X side with respect to the centers of the adhesive 17 and the adhesive 18 in the X-axis direction. As shown in fig. 14, from the state in which the end surface 11T of the carrier tape 11 is disposed on the upstream side in the conveying direction from the leading end portion 41T of the peeling member 41, the carrier tape 11 moves to the downstream side in the conveying direction, and after the leading end portion 41T of the peeling member 41 enters between the base tape 12 and the outer tape 13, the peeling member 41 moves by a predetermined amount in the + Z direction. Thereby, as shown in fig. 15, the outer tape 13 is partially peeled off from the base tape 12. In the present embodiment, the bonding of the base tape 12 and the outer tape 13 by the adhesive 17 is released in a state where the bonding of the base tape 12 and the outer tape 13 by the adhesive 18 is maintained.
After moving the peeling member 41 in the + Z direction from the initial position, the driving device 42 arranges the peeling member 41 at a predetermined position so that the bonding between the base tape 12 and the outer tape 13 by the adhesive 18 is maintained and the bonding between the base tape 12 and the outer tape 13 by the adhesive 17 is released while the carrier tape 11 is being conveyed by the conveying mechanism 30. Since the peeling member 41 is continuously disposed at a predetermined position in the Z-axis direction, the peeling member 41 can continuously support at least a part of the lower surface of the outer seal tape 13 during the conveyance of the carrier tape 11 by the conveying mechanism 30. The peeling member 41 can partially peel the outer cover tape 13 from the base tape 12 so that the bonding of the base tape 12 and the outer cover tape 13 by the adhesive material 18 is maintained and the bonding of the base tape 12 and the outer cover tape 13 by the adhesive material 17 is released.
As shown in fig. 15, the outer tape 13 is wound up at a supply position SM defined on the downstream side of the peeling member 41 in the conveying direction, and is retracted from the opening of the storage portion 14. Thus, the mounting head 5 can smoothly hold the electronic component C accommodated in the accommodating portion 14 at the supply position SM by the suction nozzle 4.
[ Effect ]
As described above, according to the present embodiment, after the leading end portion 41T of the peeling member 41 enters between the base tape 12 and the outer tape 13, the peeling member 41 is moved so as to separate at least a part of the outer tape 13 from the base tape 12, thereby peeling at least a part of the outer tape 13 from the base tape 12. Thus, when the peeling mechanism 40 is used to peel the outer tape 13 from the base tape 12, the peeling member 41 is prevented from coming into contact with the electronic component C held by the base tape 12. Therefore, the quality of the electronic component C is prevented from being degraded due to the contact between the peeling member 41 and the electronic component C, and the outer tape 13 is smoothly peeled from the base tape 12.
In the present embodiment, after the leading end portion 41T of the peeling member 41 enters between the base tape 12 and the outer tape 13, the peeling member 41 moves in the Z-axis direction while maintaining the position of the carrier tape 11 in the Z-axis direction. As described above, the carrier tape 11 is formed of a soft material and is easily flexed. Therefore, if the carrier tape 11 is moved in the Z-axis direction, the tip portion 41T of the peeling member 41 that has entered between the base tape 12 and the outer tape 13 may be separated from between the base tape 12 and the outer tape 13, or the peeling between the base tape 12 and the outer tape 13 may not be smoothly performed. According to the present embodiment, the peeling member 41 moves in the Z-axis direction with respect to the carrier tape 11 conveyed in the Y-axis direction, whereby the base tape 12 and the outer tape 13 are smoothly peeled.
Further, according to the present embodiment, the drive device 42 moves the peeling member 41 in the + Z direction intersecting the lower surface of the base tape 12 in a state where the lower surface of the outer cover tape 13 and the peeling member 41 are in contact with each other. That is, after the leading end portion 41T of the peeling member 41 enters between the base tape 12 and the outer tape 13, the peeling member 41 is moved in the + Z direction while supporting the outer tape 13 so as to be separated from the base tape 12 holding the electronic component C. Since the peeling member 41 peels at least a part of the base tape 12 and the outer tape 13 by moving the outer tape 13 in the + Z direction without moving the base tape 12 holding the electronic component C in the-Z direction, the contact between the peeling member 41 and the electronic component C held by the base tape 12 is sufficiently suppressed. Therefore, the quality of the electronic component C is prevented from being degraded due to the contact between the peeling member 41 and the electronic component C, and the outer tape 13 is smoothly peeled from the base tape 12.
In the present embodiment, the tip portion 41T of the peeling member 41 enters between the base tape 12 and the outer tape 13, and after the peeling member 41 moves by a predetermined amount in the + Z direction from the initial position, the position of the peeling member 41 in the Z axis direction is maintained at a predetermined position. Thus, after the peeling member 41 has moved by a predetermined amount in the + Z direction from the initial position, the peeling member 41 can continuously support at least a part of the lower surface of the outer seal tape 13 during the conveyance of the carrier tape 11 by the conveyance mechanism 30. Therefore, for example, as described with reference to fig. 15, the outer tape 13 can be partially peeled off from the base tape 12 so that the bonding between the base tape 12 and the outer tape 13 by the adhesive 18 is maintained and the bonding between the base tape 12 and the outer tape 13 by the adhesive 17 is released. Further, by adjusting the position of the peeling member 41 in the Z-axis direction, the outer tape 13 can be peeled off from the base member 12 as a whole, so that, for example, both the bonding of the base tape 12 and the outer tape 13 by the adhesive 17 and the bonding of the base tape 12 and the outer tape 13 by the adhesive 18 are released. As described above, the peeling state of the base tape 12 and the outer tape 13 is adjusted by adjusting the predetermined position of the peeling member 41 in the Z-axis direction.
In the present embodiment, the movement of the peeling member 41 is started after the leading end 41T of the peeling member 41 enters the end 15T of the non-storage portion 15 and before the leading end reaches the boundary 15U between the storage portion 14 and the non-storage portion 15. This sufficiently suppresses contact between the electronic component C housed in the housing portion 14 and the peeling member 41.
In the above-described embodiment, the optical sensor 80 is disposed upstream of the peeling member 41 in the conveying direction, and the timing at which the end surface 11T of the carrier tape 11 reaches the leading end portion 41T of the peeling member 41 is adjusted by calculating the time at which the end surface 11T of the carrier tape 11 reaches the leading end portion 41T of the peeling member 41 based on the distance L between the optical path of the detection light of the optical sensor 80 and the leading end portion 41T of the peeling member 41. The position of the optical path of the detection light of the optical sensor 80 and the position of the leading end portion 41T of the peeling member 41 may be substantially equal in the conveying direction. That is, the distance L may be substantially zero. In this case, the timing of starting the movement of the peeling member 41 can be determined without considering the distance L.
In the above-described embodiment, the peeling member 41 is movable obliquely in the X-axis direction. Fig. 16 is a front view schematically showing an example of the operation of the peeling mechanism 40 according to the present embodiment. In fig. 16, after the front end portion 41T of the peeling member 41 enters between the base tape 12 and the outer tape 13, the driving device 42 may move the one end portion 41A of the peeling member 41 in the X-axis direction by the 1 st distance H1 from the initial position in the + Z direction, and move the other end portion 41B of the peeling member 41 by the 2 nd distance H2 different from the 1 st distance H1 from the initial position in the + Z direction, so that the one end portion of the outer tape 13 in the width direction of the carrier tape 11, that is, the X-axis direction is separated from the base tape 12, and the other end portion of the outer tape 13 is not separated from the base tape 12. The position of the peeling member 41 may be maintained after the one end portion 41A of the peeling member 41 is moved by the 1 st distance H1 in the + Z direction from the initial position and the other end portion 41B of the peeling member 41 is moved by the 2 nd distance H2 in the + Z direction from the initial position. In a state where one end portion (-X side end portion) of the outer seal tape 13 in the X axis direction is bonded to the base tape 12 by the adhesive 17, and the other end portion (+ X side end portion) of the outer seal tape 13 in the X axis direction is bonded to the base tape 12 by the adhesive 18, the one end portion 41A (-X side end portion) of the peeling member 41 in the X axis direction is moved from the initial position in the + Z direction by the 1 st distance H1, and the other end portion 41B (+ X side end portion) of the peeling member 41 is moved from the initial position in the + Z direction by the 2 nd distance H2 shorter than the 1 st distance H1, whereby the bonding of the one end portion of the outer seal tape 13 and the base tape 12 by the adhesive 17 can be released in a state where the bonding of the other end portion of the outer seal tape 13 and the base tape 12 by the adhesive 18 is maintained.
In the above embodiment, after the leading end portion 41T of the peeling member 41 enters between the base tape 12 and the outer tape 13, the peeling member 41 may be moved in the-Z direction so that at least a part of the outer tape 13 is separated from the base tape 12 in a state where the base tape 12 and the peeling member 41 are in contact with each other. In this case, at least a part of the outer cover tape 13 and the base tape 12 can be peeled off.
