[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a perforating unit for a tape-like material, more specifically, for TAB (Tape Automated Bonding), TCP (Tape Carrier Package) T-BGA (Tape Ball Grid Array), T-CSP (Tape Chip Size Package) in a semiconductor device. The present invention relates to a perforation unit incorporated in a perforating device for a tape-shaped material such as a flexible substrate such as BGA (Ball Grid Array) or CSP (Chip Size Package) or a ceramic green sheet.
[0002]
[Prior art]
As the tape punching device described above, the prior arts disclosed in JP-A-10-180691 and JP-A-10-180692 are already known.
In this prior art, a perforating unit and a tension mechanism for sandwiching the tape-like material and applying a tension are provided between a feeding mechanism for feeding the roll material of the tape-like material and a winding mechanism for winding it. The basic configuration is such that the punching unit is controlled in the Y-axis direction while the tape-like material is quantitatively fed in the X-axis direction by a pair of upper and lower feed rollers, one of which is a pinch roller, and punching is performed with a punch with a required drilling pattern.
And the tape-like material moves in parallel in the Y-axis direction due to friction with the punch, etc., and there is a slight difference in frictional resistance between the pair of upper and lower feed rollers, the feeding mechanism (feeding roll), and the winding mechanism (winding roll). Similarly, the edge detection means for detecting the parallel movement of the tape-like material is arranged on both sides (above both longitudinal edges of the tape-like material), and the feeding mechanism (feeding roll) and winding by the output signal of the edge detection means. The mechanism (winding roll) is simultaneously controlled in the plus or minus direction (Y-axis direction) to correct it.
By the way, this type of tape-like material was based on widths of 30 mm, 48 mm, and 96 mm, but nowadays, there is a wide tape-like material having a width dimension of, for example, about 300 mm. There are many voices of users who want to drill a large number of product holes for each processing area partitioned in the vertical and horizontal directions of the tape-like material, and countermeasures are urgently seen.
[0003]
However, in order to meet the demand, a gang die equipped with a centering camera is installed in the punching unit as in the conventional case, and the punching unit itself is orthogonal to the feed direction (X-axis direction) of the tape-like object. The drilling unit is configured to be controllable in two directions (Y-axis direction), and is based on centering data obtained by centering camera imaging of a reference mark that is performed every time a fixed amount of tape-like material is fed intermittently. It is only necessary to correct itself in the X and Y axis directions. However, in the method in which the perforating unit to be weighted is controlled to move in the two directions, it is controlled by a drive mechanism having a large output in both the X axis direction and the Y axis direction. It is necessary to do this, and it is difficult to say that it is suitable for improving the positioning accuracy and perforating with high accuracy.
In addition, in order to correct the positional deviation of the tape-like material in the Y-axis direction as described above, a separate drive source is required to move the feeding mechanism (feeding roll) and the winding mechanism (winding roll) itself. To do.
Further, the pair of feed rollers are made of rubber in detail, and have a property of easily causing a slip between the pair of feed rollers. Therefore, in practice, the surface of the tape-like material is printed by increasing the contact pressure so that the entire length in the longitudinal direction of the roller is in strong contact with the entire length of the tape-like material. If there is, there is a risk of damaging the printing.
[0004]
[Problems to be solved by the invention]
The present invention has been made in view of the above-mentioned conventional circumstances, and the purpose of the process is to batch-drill a large number of product holes with a gang die for each processing area partitioned on the vertical and horizontal rows of a wide tape-like product. As a means of controlling the gang die in the direction (X axis direction) orthogonal to the tape feed direction (X axis direction), a high output drive mechanism is not required and the product holes are accurately punched in each processing area. An object of the present invention is to provide a perforating unit suitable for this purpose.
Another object is to provide a perforating unit having a simple structure for correcting displacement in a direction (Y-axis direction) perpendicular to the feeding direction (X-axis direction) of the tape-like material.
Yet another object is to provide a perforation unit that does not impair the quality of the tape.
[0005]
[Means for Solving the Problems]
As technical measures taken to solve the above purpose , A flexible tape-like perforation unit having an internal hollow mold housing frame that has a tape-like material loading / unloading port and that can be corrected in the tape feed direction (X-axis direction). And a gang die comprising a die set having a driving drive unit, a punch holding die, and a die holding die housed in the die housing frame, and the gang die is orthogonal to the feeding direction (X-axis direction) of the tape-like object. Controllable in direction (Y axis direction) There is something that was made. The gang die includes a centering camera that images and centers a reference mark for drilling each processing area attached to a tape-like object.
[0006]
In this means, a tape-like object is intermittently fed in a certain amount in the X-axis direction, and a gang die is controlled and moved in the Y-axis direction to secure a plurality of centering cameras in a row in the width direction of the tape-like object. Each time an image is taken by positioning it directly above each fiducial mark in the processing area, the mold receiving frame is corrected in the X-axis direction with the centering data and the gang die is corrected in the Y-axis direction, and the punch holding mold is lowered. Then, product holes are drilled in batches for each processing area.
[0007]
And According to the present invention, A flexible tape-like perforation unit having an internal hollow mold housing frame that has a tape-like material loading / unloading port and that can be corrected in the tape feed direction (X-axis direction). A gang die formed of a die set including a punch holding die and a die holding die, which is housed in the die housing frame, and a striking drive unit is provided in the mold housing frame so as not to move, and the gang die is driven by striking The impact transmission force can be transmitted to the part, and can be supported so as to be controllable in a direction (Y-axis direction) perpendicular to the tape feed direction (X-axis direction). Here, providing the striking drive unit immovably on the mold housing frame means that the striking driving force can be transmitted to the gang die but does not move in both the X-axis direction and the Y-axis direction.
[0008]
With this means, the control dynamic load in the Y-axis direction can be suppressed to be smaller than that when the gang die is controlled and moved in the Y-axis direction together with the striking drive unit.
[0009]
And , The front space of the mold housing frame is configured to be able to communicate with the loading / unloading port by opening and closing the front plate of the mold housing frame that constitutes the front opening edge in the Y-axis direction of the loading / unloading port in the mold housing frame. In addition, the guide post having the gang die as a die set is fixed to the punch holding die side, and the lower end of the guide post is guided with respect to the die holding die so that the punch holding die is higher than that at the time of punching. When the guide post is raised, the lower end of the guide post may come out of the die holding die, and a tape-like object insertion / extraction space may be formed between the lower end of the guide post and the die holding die.
[0010]
With this means, when trouble occurs due to breakage of the punch or the like, the tape-like material can be extracted into the front space of the mold holding frame without intentionally cutting the tape-like material.
[0011]
More , A tape guide part is integrally extended horizontally at least at the carry-in port of the mold housing frame toward the upstream side, and the tape guide part wraps and guides the part from the lower surface of the tape-like object to both longitudinal edges. It is preferable to be configured in a form. Here, the drive source of the pair of upper and lower feed rollers uses a servo motor, a pulse motor or the like that can electrically control the rotation amount of the feed roller, and a type that drives only one feed roller, There is a type in which the driving force is transmitted to the feed roller, and in this case, the other feed roller may be configured to communicate with the drive source by a transmission means (gear, belt) or the like.
[0012]
By adopting such means, the tape guide portion integrally provided in the mold housing frame is tape-shaped in the direction (Y-axis direction) perpendicular to the feeding direction (X-axis direction) of the tape-like material. Prevent misalignment of objects.
[0013]
Also , The tape guide unit is provided with a pair of upper and lower feed rollers that sandwich the tape-like object from above and below and intermittently feed it to the gang die with a certain amount, and the pair of upper and lower feed rollers are provided at locations other than the processing area of the tape-like object. It is more preferable that the rollers are arranged to be sandwiched and at least one of the roller surfaces of the feed roller is processed into a rough surface. Here, the processing on the rough surface refers to engraving knurled eyes, flat eyes, glazed eyes, check eyes, or the like, or performing surface treatment in an uneven shape. Further, the portion other than the processing area of the tape-like product is a non-processing area that is not punched by a gang die with a required product hole drilling pattern. That is, in the wide tape-like object of the present invention that divides a plurality of rows of processing areas in the width direction, both edge portions and the band-like portions between the rows are non-working areas. Furthermore, when the arrangement is made such that a portion other than the processing area of the tape-like material is sandwiched, the upper feed roller is arranged so that the roller surface is in direct contact with the non-processing area on the upper surface of the tape-like material. In addition, the lower feed roller is configured such that the roller surface comes into contact with the lower surface of the tape-like material through a contact opening formed in a sliding contact plate portion (lower surface portion) where the lower surface of the tape-like material is in sliding contact with the tape guide portion.
[0014]
According to this means, intermittent constant feeding of the tape-like material by driving the feed roller is performed without slipping on the rough surface applied to the roller surface of one or both of the feed rollers.
In addition, a tape-like material having unevenness in printing or the like can be sent without damaging the printing or the like.

When the punch holding die 22 is lifted higher than the time of drilling by using the space 123, the lower end of the post body 35 is a die holding die ( In detail, the die pad 321) 32 is pulled out, and an insertion / removal space 100 ′ of the tape-like object 100 is formed between the lower end of the post body 35 and the extension arm 324.
Since the front plate 71 constitutes the front edge of the carry-in entrance 11 and the carry-out port 21, the front plate 71 is removed so that a tape-like shape can be obtained without cutting when trouble such as a perforation error occurs. The object 100 can be extracted from the carry-in port 11 and the carry-out port 21 to the front space of the mold housing frame 1.
In this embodiment, the front plate 71 is not provided, and the front plate 71 is moved away from the front side by making the front surface of the mold holding frame 1 open and the carry-in port 11 and the carry-out port 21 cut out from the front side. Without removing, the tape-like object 100 may be extracted from the insertion / removal space 100 ′.
Further, in the case of this embodiment, the tape guide portion 3 having a structure in which the tape guide portion 3 is not provided or the tape-like object 100 can be pulled out and inserted using the flexibility thereof from above. Need to use. The latter case can be easily dealt with by adopting a configuration of the tape guide portion 3 in which the connecting rod 17e is not installed.

(B) extends the extension arms 324 and 227 only rearward. An area indicated by a two-dot chain line is an attachment-corresponding surface with the gang die 2, and a processing area E in which a plurality of gang dies 2 are secured in a row in the width direction (Y-axis direction) of the tape-like object 100 in the same manner as described above. When the control movement is performed in the Y-axis direction so as to be positioned directly above the processing area E on both sides of the above, the two pairs of front and rear guide posts (specifically, post bodies 35) 5 are the length of the tape-like object 100. As in the first, second, and third embodiments, the extension arms 324 and 227 are extended with a necessary length that does not collide with the edge.
Although not shown in the figure, the extension arms 324 and 227 may be extended only forward from the die plate 323 and the punch plate 223, and the structure may be completely opposite to that shown in FIG. 9B.
In the case of the configuration shown in FIG. 9B, unlike FIG. 9A, the tape-like object 100 is moved forward of the mold housing frame 1 during an accident without forming the insertion / extraction space 100 ′ of the tape-like object 100. Can be extracted into space.

A gang die composed of a die set having a driving unit, a punch holding die, and a die holding die is provided on the frame so as to be controllable in a direction (Y axis direction) perpendicular to the tape feed direction (X axis direction). Because of the configuration, only the gang die is used during the control operation in the Y-axis direction so that the gang die is aligned with a plurality of processing areas that are partitioned in a row in the width direction of a tape-shaped article having a wide width (for example, 300 mm width). Compared with the case where the drilling unit itself equipped with a gang die is controlled to move in both the X and Y axis directions, a high output drive mechanism is not required for the control movement in the Y axis direction. It is possible to provide a punching unit of the preferred tape-like product in terms of a degree positioning drilling performed.
Pa A holding-type striking drive unit is provided in the mold housing frame so as not to move, and the gang die can transmit a striking transmission force to the striking drive unit, and the tape feed direction (X-axis direction) When supported so as to be controllable in an orthogonal direction (Y-axis direction), the entire weight of the striking drive unit does not become a load of gang die control motion, and a further small output drive mechanism (in the Y-axis direction) Control with a drive mechanism) becomes possible.
Pa When a perforation error occurs due to breakage of the punch, etc., it can be conveniently handled by pulling it out from the mold housing frame to its front space without cutting the tape-like material.
(Claim 4) In the case where the tape guide portion is integrally extended horizontally at least at the carry-in port of the mold housing frame toward the upstream side, the feeding mechanism and the winding mechanism are controlled by the drive source. Without incurring an increase in equipment costs due to the large scale as in the past, the position of the tape-like object (direction perpendicular to the feeding direction of the tape-like object (Y-axis direction) )) Can be prevented.
Ma In addition, since at least one roller surface of the feed roller is processed into a rough surface, it does not slip, and the quantitative intermittent feed of the tape-like material to the punching unit of the present invention is not only highly accurate, but also printing. Can be performed while maintaining the required drilling quality.
