Description

Technical Field

[0001] The present invention relates to a taping device for enclosing electronic components by attaching a cover tape to a carrier tape in which the electronic components are placed in pockets.

Background Art

[0002] When enclosing electronic components that have undergone a predetermined inspection such as an electrical characteristic inspection with a carrier tape and a cover tape and shipping them, a taping device for attaching a cover tape to a carrier tape in which the electronic components are placed in pockets is used (see Patent Documents 1 and 2). The carrier tape with the cover tape attached is wound around a drum, and the drum is replaced at the timing when the carrier tape wound around the drum reaches a predetermined length.

[0003] Since the replacement of the drum is performed with the taping device stopped, the process of enclosing the electronic components in the carrier tape is also stopped while the drum is being replaced. To avoid this stop of the enclosing process of the electronic components, it is conceivable to adopt a design in which two taping devices are provided and a component transfer device capable of transferring the electronic components to the two taping devices is provided, and while replacing the drum corresponding to one of the taping devices, the enclosing process of the electronic components is performed by the other taping device.

[0004] Also, if a plurality of taping devices are prepared and a component transfer device capable of transferring the electronic components to the plurality of taping devices is provided, the electronic components can be ranked based on the inspection results, and carrier tapes in which only the electronic components of the same rank are enclosed can be generated in the number of ranks.

Embodiments for Carrying Out the Invention

[0010] Subsequently, with reference to the attached drawings, embodiments embodying the present invention will be described to facilitate understanding of the present invention. As shown in FIGS. 1, 2, and 3, a taping device 10 according to an embodiment of the present invention includes carrier tapes S1, S2 into which electronic components W are respectively loaded into pockets P1, P2, a tape lane 11 through which a cover tape T1 attached to the carrier tape S1 is fed, and a tape lane 12 through which a cover tape T2 attached to the carrier tape S2 is fed. Details will be described below.

[0011] As shown in FIGS. 1, 2, and 3, the taping device 10 includes a plate-shaped movable base 16 that is reciprocally movable in the X-axis direction along linear guide rails 14, 15 fixed to a base 13, and a plate-shaped movable base 19 that is reciprocally movable in the Y-axis direction perpendicular to the X-axis direction along linear guide rails 17, 18 fixed to the movable base 16. In the present embodiment, both the X-axis direction and the Y-axis direction are horizontal directions.

[0012] A driving means 20 for applying a force in the X-axis direction to the movable base 16 is attached to the base 13, and a driving means 21 for applying a force in the Y-axis direction to the movable base 19 is attached to the movable base 16. In the present embodiment, the driving means 20 (and also the driving means 21) is configured to have a ball screw and a motor that applies a rotational force to the ball screw, but is not limited thereto.

[0013] Linear guide rails 22 and 23 along the X-axis direction are respectively fixed to the movable table 19. The guide rails 22 and 23 are parallel, and a cubic movable unit 24 is attached to the guide rails 22 and 23 so as to be reciprocally movable along the guide rails 22 and 23. A driving means 25 for applying a force in the direction (X-axis direction) along the guide rails 22 and 23 to the movable unit 24 is attached to the movable table 19. The driving means 25 is also configured to have a ball screw and a motor, similar to the driving means 20 and 21, but is not limited thereto.

[0014] As shown in FIG. 3, the movable unit 24 is provided with pulleys 26, 27, 28, and 29 at the upper part, which are respectively given rotational force from servo motors (not shown). The pulleys 26 and 27 are equal in position in the X-axis direction and are arranged at intervals in the Y-axis direction. The pulley 28 is arranged adjacent to the pulley 26 in the X-axis direction, and the pulleys 28 and 29 are the same in position in the X-axis direction and are arranged at intervals in the Y-axis direction.

[0015] Near the movable unit 24, a first tape supply drum around which an empty carrier tape S1 with no electronic component W in the pocket P1 is wound, and a first tape take-up drum around which the carrier tape S1 enclosing the electronic component W and the cover tape T1 are wound are arranged. Near the movable unit 24, further, a second tape supply drum around which an empty carrier tape S2 with no electronic component W in the pocket P2 is wound, and a second tape take-up drum around which the carrier tape S2 enclosing the electronic component W and the cover tape T2 are wound are arranged.

[0016] That is, in the present embodiment, two (an example of N) tape supply drums and tape take-up drums are respectively provided. However, N is an integer of 2 or more. The first tape supply drum and the first tape take-up drum correspond to the pulleys 26 and 27. The carrier tape S1 is hung on the pulleys 26 and 27 and is intermittently sent from the first tape supply drum toward the first tape take-up drum by repeating the rotation and temporary stop of the pulleys 26 and 27.

[0017] The second tape supply drum and the second tape take-up drum correspond to pulleys 28 and 29. The carrier tape S2 is wound around the pulleys 28 and 29, and is intermittently sent from the second tape supply drum toward the second tape take-up drum by the repeated rotation and temporary stop of the pulleys 28 and 29. The control of the rotation and temporary stop of pulleys 26 and 27 and the control of the rotation and temporary stop of pulleys 28 and 29 are independent of each other. Therefore, the movement and stop of each of the carrier tapes S1 and S2 can also be independently controlled. For example, one of the carrier tapes S1 and S2 can be moved while the other is stopped. Note that the first and second tape supply drums and the first and second tape take-up drums are not shown in the drawings. Also, in FIGS. 1 and 5, the description of the electronic components W in the pockets P1 and P2 is omitted.

[0018] In the present embodiment, the conveyance path through which the carrier tape S1 is sent from the first tape supply drum toward the first tape take-up drum is defined as tape lane 11, and the conveyance path through which the carrier tape S2 is sent from the second tape supply drum toward the second tape take-up drum is defined as tape lane 12. The tape lanes 11 and 12 are arranged in parallel. That is, in the present embodiment, there are two tape lanes 11 and 12 (an example of N lanes), which are arranged in parallel.

[0019] In the vicinity of the taping device 10 including the base 13, the movable bases 16 and 19, the driving means 20, 21, and 25, and the movable unit 24, as shown in FIGS. 1 and 2, there is provided a component conveyance device 30 that transfers the electronic components W acquired from the outside and supplies them to the tape lanes 11 and 12. The component conveyance device 30 includes a conveyance unit 31 that acquires the electronic components W from the outside (in the present embodiment, a wafer sheet U, but not limited thereto), a conveyance unit 32 that acquires the electronic components W from the conveyance unit 31, and a conveyance unit 33 that acquires the electronic components W from the conveyance unit 32.

[0020] The transfer unit 31 includes a rotating body 34 and a plurality of suction nozzles 35 arranged at equal intervals along a virtual circumference centered on the rotating body 34. Each suction nozzle 35 sucks the electronic component W by vacuum pressure and releases the sucked electronic component W by opening to the atmosphere or blowing air. The transfer units 32 and 33 also have the same configuration as the transfer unit 31, and each has a rotating body 34 and the same number of suction nozzles 35 as the transfer unit 31. In the present embodiment, the transfer units 31, 32, and 33 are arranged such that the rotation axes of their respective rotating bodies 34 are parallel, but other arrangements are also possible, and the number of transfer units does not have to be three.

[0021] In the present embodiment, as shown in FIG. 2, the suction nozzle 35 of the transfer unit 31 acquires and sucks the electronic component W from the wafer sheet U at the 3 o'clock position, and moves to the 9 o'clock position together with the electronic component W by the counterclockwise rotation of the rotating body 34 of the transfer unit 31, and gives the electronic component W to the suction nozzle 35 of the transfer unit 32. The transfer unit 32 also gives the electronic component W acquired from the transfer unit 31 to the transfer unit 33 by the same operation as the transfer unit 31. In the transfer unit 33, the suction nozzle 35 moves to the 6 o'clock position by the counterclockwise rotation of the rotating body 34, and the sucked electronic component W is put into the pocket P1 of the carrier tape S1 arranged on the tape lane 11 or the pocket P2 of the carrier tape S2 arranged on the tape lane 12.

[0022] Here, taking the arrangement area of the pocket P1 or the pocket P2 into which the electronic component W can be put by the transfer unit 33 into the pocket P1 of the carrier tape S1 or the pocket P2 of the carrier tape S2 as the insertable area R, the driving means 25 can move the movable unit 24 (tape lanes 11, 12) so that either one of the pocket P1 of the carrier tape S1 or the pocket P2 of the carrier tape S2 is arranged in the insertable area R.

[0023] The insertable area R is an area composed of both an area where the electronic component W can be surely inserted into the pocket P1 or the pocket P2 and an area where, although uncertain, it is possible to insert the electronic component W. In the present embodiment, the insertable area R is larger than the size of one pocket P1 (the sizes of the pockets P1 and P2 are equal), but is of a size that cannot accommodate two pockets P1, two pockets P2, or the pockets P1 and P2 adjacent in the X-axis direction. Therefore, only one of the pockets P1 or one of the pockets P2 is arranged in the insertable area R.

[0024] The driving means 25 horizontally moves the movable unit 24 by an interval between the center in the width direction of the tape lane 11 and the center in the width direction of the tape lane 12 in the X-axis direction with respect to the movable table 19 by one operation. Therefore, as shown in FIG. 1, when the driving means 25 operates in a state where one pocket P1 is arranged in the insertable area R, as shown in FIG. 4, one pocket P2 is arranged in the insertable area R, and as shown in FIG. 4, when the driving means 25 operates in a state where one pocket P2 is arranged in the insertable area R, as shown in FIG. 1, one pocket P1 is arranged in the insertable area R. Accordingly, the driving means 25 switches the tape lanes 11 and 12, a part of which is arranged in the insertable area R.

[0025] Also, as shown in FIG. 2, in the vicinity of the conveyance unit 32, an electrical characteristic inspection unit 36 that performs an electrical characteristic inspection on the electronic component W adsorbed by the suction nozzle 35 of the conveyance unit 32 is fixed to a support member (not shown) in the vicinity of the conveyance unit 33, and imaging means 37 and 38 for performing imaging are respectively fixed to a support member (not shown). As shown in FIG. 5, the imaging means 37 is connected to a defect detection unit 40 that detects an abnormality in the appearance such as cracking or chipping of the electronic component W based on the image of the electronic component W imaged by the imaging means 37. The imaging means 38 is connected to a position detection unit 41 that detects the position of the electronic component W with respect to the conveyance unit 33 based on the image of the electronic component W imaged by the imaging means 38.

[0026] In the vicinity of the movable unit 24, as shown in FIG. 3, imaging means 44 (an example of processing means for performing predetermined processing on the carrier tape S1 or the carrier tape S2), which images either the empty pocket P1 of the carrier tape S1 arranged in the insertable region R or the empty pocket P2 of the carrier tape S2 arranged in the insertable region R via the light reflecting members 42 and 43, is fixed to a support member (not shown). As shown in FIG. 5, the imaging means 44 is connected to a position detection unit 45 that detects the position of the pocket P1 or the pocket P2 arranged in the insertable region R based on the image captured by the imaging means 44.

[0027] The electrical characteristic inspection unit 36 and the defect detection unit 40 are connected to a control means 46 connected to the drive means 20, 21, 25. The control means 46 can be constituted by a CPU, a memory, etc. In the present embodiment, based on the inspection result of the electrical characteristic inspection unit 36 and the detection result of the defect detection unit 40, the control means 46 selects either the pocket P1 of the carrier tape S1 or the pocket P2 of the carrier tape S2 as the insertion destination of the next electronic component W for the transport unit 33, moves the movable unit 24 on the movable table 19 by controlling the drive means 25, and arranges the selected pocket P1 or pocket P2 in the insertable region R.

[0028] In the present embodiment, the electronic components W whose results of both the electrical characteristic inspection and the appearance inspection are both at a rank (good rank) of a predetermined level or higher are inserted into the pocket P1 of the carrier tape S1, and the electronic components W whose any one of the same results is at a rank lower than the predetermined level are inserted into the pocket P2 of the carrier tape S2. When the pocket P1 corresponding to the tape lane 11 is arranged in the insertable region R, the imaging means 44 can image the corresponding pocket P1, and when the pocket P2 corresponding to the tape lane 12 is arranged in the insertable region R, the imaging means 44 can image the corresponding pocket P2. That is, the imaging means 44 is shared for the two rows of tape lanes 11 and 12.

[0029] In the present embodiment, for imaging means 44 which is an example of processing means, a lane moving mechanism that moves two rows of tape lanes 11 and 12 and arranges either one of the two rows of tape lanes 11 and 12 at an imaging possible position (an example of a processable position) where the imaging means 44 can perform imaging (predetermined processing) on the tape lane 11 (or tape lane 12) is constituted by guide rails 22 and 23 and driving means 25.

[0030] Also, taking the position of pocket P1 (or pocket P2) within the insertable region R where the transport unit 33 can surely insert the electronic component W as the target position, movement amount calculation means 47 for calculating the moving direction and moving amount of the movable unit 24 for arranging the pocket P1 (or pocket P2) arranged in the insertable region R at the target position is connected to the position detection units 41 and 45. In the present embodiment, the movement amount calculation means 47 derives the target position based on the position of the electronic component W with respect to the transport unit 33 to be inserted into the pocket P1 (or pocket P2) next (that is, the detection result of the position detection unit 41). Note that, depending on the equipment, a target position common to each electronic component W is determined.

[0031] Each time an empty pocket P1 is arranged in the insertable region R due to the movement of the carrier tape S1 by the pulleys 26 and 27, the movement amount calculation means 47 derives the moving direction and moving amount of the movable unit 24 for arranging the pocket P1 at the target position corresponding to the pocket P1. The reason for deriving the moving direction and moving amount of the movable unit 24 for each individual pocket P1 is that the position of the pocket P1 when arranged in the insertable region R differs (strictly speaking, is different) for each pocket P1.

[0032] The same applies to the pocket P2. Each time an empty pocket P2 is arranged in the insertable region R due to the movement of the carrier tape S2, the movement amount calculation means 47 derives the moving direction and moving amount of the movable unit 24 for arranging the pocket P2 at the target position. Therefore, the taping device 10 includes a moving amount calculation means 47 for deriving the moving direction and moving amount of the two tape lanes 11 and 12 for arranging the empty pocket P1 or the empty pocket P2 at the target position based on the images captured by the imaging means 38 and the images captured by the imaging means 44.

[0033] The defect detection unit 40 and the position detection units 41 and 45 can be configured by a chip or the like on which an image processing program is installed, and the moving amount calculation means 47 can be configured by a CPU, a memory, and the like. The control means 46 and the moving amount calculation means 47 are connected, and the control means 46 arranges the pocket P1 (or the pocket P2) arranged in the insertion possible region R at the target position by adjusting the position of the movable unit 24 by the operation of the driving means 20 and 21 based on the derivation result of the moving amount calculation means 47. In the present embodiment, the tape lanes 11 and 12 are integrally translated in parallel by the operation of the driving means 20 and 21.

[0034] Hereinafter, a process of inserting the electronic component W (hereinafter, also referred to as "target electronic component W") into the empty pocket P2 in a state where the empty pocket P1 is arranged in the insertion possible region R will be described. (1) At the timing when the transport unit 33 transports the target electronic component W to the insertion possible region R, the control means 46 moves the movable unit 24 by controlling the driving means 25 and arranges one pocket P2 in the insertion possible region R.

[0035] (2) The imaging means 44 images the pocket P2 arranged in the insertion possible region R, and the position detection unit 45 detects the position of the pocket P2 from the captured image. (3) The moving amount calculation means 47 obtains the target position based on the position of the target electronic component W detected by the position detection unit 41 and the position of the pocket P2 detected by the position detection unit 45 based on the captured image of the imaging means 38, and derives the moving direction and moving amount of the movable unit 24 for arranging the pocket P2 at the target position.

[0036] (4) The control means 46 controls the drive means 20 and 21 based on the derivation result of the movement amount calculation means 47 to adjust the position of the movable unit 24 in the X-axis direction and the Y-axis direction, and arranges the pocket P2 within the insertable region R at the target position. (5) The transport unit 33 inserts the target electronic component W into the pocket P2 arranged at the target position.

[0037] Further, instead of imaging the empty pocket P1 (or pocket P2) arranged in the insertable region R, the imaging means 44 may image the empty pocket P1 (or pocket P2) before being arranged in the insertable region R. For example, when the imaging means 44 images the pocket P1 (or pocket P2) one upstream side of the insertable region R, the movement amount calculation means 47 associates the position of the pocket P1 (or pocket P2) detected by the position detection unit 45 based on the captured image of the imaging means 44 with the corresponding tape lane 11 (in the case of pocket P2, associates the position of pocket P2 with the corresponding tape lane 12) and stores it, and uses the stored position (position information) of the pocket P1 (or pocket P2) for deriving the movement direction and movement amount of the movable unit 24 (tape lanes 11, 12) for arranging the pocket P1 (or pocket P2) at the target position.

[0038] In this case, the control means 46 controls the drive means 20 and 21 (and also the drive means 25 if switching of the tape lanes 11 and 12 is necessary) at the timing when the tape lane 11 moves by the pulleys 26 and 27 (the timing when the pocket P1 one upstream side of the insertable region R moves into the insertable region R) to adjust the position of the movable unit 24 and arranges the pocket P1 one upstream side of the insertable region R at the target position.

[0039] Also, after the electronic component W is inserted into the pocket P1, when inserting the next electronic component W into the pocket P2, based on the image captured when the corresponding pocket P2 is arranged one upstream side of the insertion possible region R, the moving direction and the moving amount of the movable unit 24 for arranging the pocket P2 at the target position are derived using the position of the pocket P2 detected and stored associated with the tape lane 12.

[0040] In addition to this, the imaging means 44 may be designed to image the empty pocket P1 (or pocket P2) before being arranged in the insertion possible region R, that is, a plurality of pockets P1 (or pocket P2), together with the pocket P1 (or pocket P2) arranged in the insertion possible region R, or may image one or a plurality of pockets P2 together with one or a plurality of pockets P1. In that case, for example, the positions of the plurality of pockets P1 and P2 can be detected in one image.

[0041] In the step (1) above, instead of performing the process of switching from the state where the pocket P1 is arranged in the insertion possible region R to the state where the pocket P2 is arranged in the insertion possible region R by moving the movable unit 24 with respect to the movable table 19 under the control of the driving means 25, it can be performed by moving the movable body 16 with respect to the base table 13 under the control of the driving means 20. In this case, a lane moving mechanism that moves the two rows of tape lanes 11 and 12 and arranges either one of the tape lanes 11 and 12 at a processable position where the processing means can perform a predetermined process is constituted by the guide rails 14 and 15 and the driving means 20.

[0042] Conversely, in the step (4) above, instead of performing the process of matching the X-axis direction position of the pocket P2 with the X-axis direction position of the target position by moving the movable body 16 with respect to the base table 13 under the control of the driving means 20, it can also be performed by moving the movable unit 24 with respect to the movable table 19 under the control of the driving means 25.

[0043] Therefore, it is possible to omit either the mechanism for moving the movable body 16 in the X-axis direction with respect to the base 13 by the driving means 20 or the mechanism for moving the movable unit 24 in the X-axis direction with respect to the movable base 19 by the driving means 25. However, since the movement in the X-axis direction in the step (1) and the movement in the X-axis direction in the step (4) differ in the amount of movement and the required movement accuracy, it is preferable to provide mechanisms with different designs suitable for each movement in the X-axis direction. In the present embodiment, such a preferable configuration is adopted.

[0044] Then, in the step (4), instead of performing the process of matching the Y-axis direction position of the pocket P2 with the Y-axis direction position of the target position by moving the movable base 19 with respect to the movable body 16 under the control of the driving means 21, it may be performed by moving the carrier tape S2 by the rotation of the pulleys 28 and 29 (for adjusting the Y-axis direction position of the pocket P1, it is performed by moving the carrier tape S1 by the rotation of the pulleys 26 and 27).

[0045] Further, in the present embodiment, as shown in FIGS. 3 and 4, on the downstream side of the insertable region R, an imaging means 48 for imaging the electronic component W in the pocket P1 of the carrier tape S1 without the cover tape T1 attached or the electronic component W in the pocket P2 of the carrier tape S2 without the cover tape T2 attached is fixed to a support member (not shown). Based on the captured image of the imaging means 48, it is determined whether the electronic component W protrudes from the pocket P1 or the pocket P2.

[0046] Then, a tape sticking means 49 is provided downstream of the position where the pocket P1 (or pocket P2) is imaged by the imaging means 48 (i.e., downstream of the insertable region R) to stick a cover tape T1 to the carrier tape S1 (or a cover tape T2 to the carrier tape S2) by pressure bonding or the like. Further downstream, an imaging means 50 for imaging the bonding portion of the cover tape T1 stuck to the carrier tape S1, i.e., the bonding portion between the carrier tape S1 and the cover tape T1 (or the bonding portion of the cover tape T2 stuck to the carrier tape S2, i.e., the bonding portion between the carrier tape S2 and the cover tape T2) is fixed to a support member (not shown).

[0047] The imaging means 48 and 50 are each also used for the two rows of tape lanes 11 and 12, and are an example of processing means for performing a predetermined process on the electronic component W inserted into the pocket P1 (or pocket P2). The tape sticking means 49 is also used for the two rows of tape lanes 11 and 12, and is an example of processing means for performing a predetermined process on the carrier tape S1 and the cover tape T1 (or the carrier tape S2 and the cover tape T2). Therefore, in the present embodiment, at least one processing means is provided that is also used for the two rows of tape lanes 11 and 12 and performs a predetermined process on any one or more of the carrier tapes S1 and S2, the electronic component W inserted into the pockets P1 and P2, and the cover tapes T1 and T2.

[0048] As described above, the embodiments of the present invention have been described. However, the present invention is not limited to the above-described forms, and all changes and the like that do not depart from the gist are within the scope of application of the present invention. For example, as a component transport device for transporting electronic components to a taping device, a component transport device 60 that suspends and supports an electronic component W as shown in FIG. 6 or other designed component transport devices can be adopted. Also, as shown in FIGS. 7 and 8, the tape lanes may be three or more columns (in the examples shown in FIGS. 7 and 8, three tape lanes 70, 71, and 72 are provided). The N tape lanes do not have to move integrally. As shown in FIGS. 8 to 10, a lane moving mechanism may be adopted to individually move N movable units (in the examples shown in FIGS. 7 to 10, three movable units 73, 74, and 75 each provided with a tape lane 70, 71, and 72), and each tape lane may be moved individually.

[0049] Furthermore, as shown in FIG. 11, a taping device 80 may be adopted in which tape lanes 81, 82, and 83 are arranged radially around a position Q in a plan view. In a plan view, the position where three extension lines obtained by extending the tape lanes 81, 82, and 83 intersect is set as the position Q. The tape lanes 81, 82, and 83 move so as to rotate around the position Q, and various adjustments are made so that one of the tape lanes 81, 82, and 83 is disposed directly below the transport unit 84.

[0050] Also, at least one processing means for performing a predetermined process on any one or more of the carrier tape, the electronic components placed in the pocket, and the cover tape, which is also used for the N tape lanes, may be provided. For example, only an imaging means for imaging either one or both of an empty pocket arranged in the insertable area and an empty pocket before being arranged in the insertable area is used as a processing means common to the N tape lanes, and N imaging means for imaging the electronic components in the pocket on the downstream side of the insertable area, a tape attaching means, and an imaging means for imaging the adhesive portion of the cover tape attached to the carrier tape may be provided respectively.
