Description

The present invention relates to a punching device and a positioning / adjusting device thereof. For example, the punching device is suitable for punching a paper sheet as a stationery or a film tape for movies or a flexible printed wiring board for mounting electronic components. Carrier tape (TAB (Tape Automated Bonding) tape, COF (Chip on Film) tape, BGA (Ball Grid Array)
Tape, CSP (Chip Size Package) tape, ASIC (Application Specific Integrated Circuit) tape, double-sided wiring tape (hereinafter simply referred to as “film carrier tape for mounting electronic components” or “film carrier tape”), wide tape or sheet F
The present invention relates to a punching device suitable for displaying a defect such as a defective preliminary mark hole at a predetermined position of a defective piece before inspection in a PC (Flexible Printed Circuit) inspection, and a positioning adjustment device thereof.

  With the development of the electronics industry, the demand for printed wiring boards for mounting electronic components such as IC (Integrated Circuit) chips and LSI (Large Scale Integrated Circuit) chips is increasing rapidly. Recently, as a method for mounting these electronic components, film carrier tapes for mounting electronic components such as TAB tape, COF tape, BGA tape, ASIC tape, double-sided wiring tape, and multilayer wiring tape are used. The same mounting method was adopted. In particular, flats such as liquid crystal display elements (LEDs) and PDPs (plasma display panels) that require high definition, thinning, and narrowing of the frame area of liquid crystal screens such as personal computers, mobile phones, and liquid crystal televisions. Its importance is increasing in the electronics industry using display panels and the like.

  Furthermore, recently, the demand for film carrier tapes for mounting electronic components has greatly increased with the shift to color liquid crystal displays for mobile phones, and film carriers in the field of print control for printers connected to personal computers. The demand for tape has also increased significantly.

  Such a film carrier tape for mounting electronic parts is generally manufactured through processing steps such as an etching / resist peeling step, a solder resist processing step, an electrical inspection step, and an appearance inspection step.

  In the inspection process of electronic component mounting carrier tape, for example, in the electrical inspection process and appearance inspection process, when the inspection result is judged to be defective, the electronic component such as an IC chip of the defective piece is mounted as a customer-specified defect display. Basically, the above-mentioned electronic parts cannot be mounted by cutting out the parts to be mounted. However, a fixed small through-hole or ink that temporarily becomes a defective preliminary mark on the defective piece is automatically in-line at a predetermined position. Perforated or marked.

  The reason for this is that the customer-specified defect display differs in display method and display size for each customer as well as for each product type. In addition, it is for automatically punching out the defect indication mark specified by the customer using the respective molds. By doing so, it is possible to facilitate the defect display management of the film carrier tape for mounting electronic components, reduce the management defect, and improve the production efficiency.

By the way, when inspection such as visual appearance inspection of the film carrier tape for mounting electronic components is performed, for example, when a defect such as a foreign object or a bent inner lead or a defective wiring pattern is detected, the operator A hand-held manual punching device as shown in Patent Document 1 is held, and a defective preliminary mark hole is formed at a predetermined position of a defective piece of the electronic component mounting film carrier tape in which a defect is detected.

Usually, this defective preliminary mark hole is generally formed at the center in the width direction of the film.
And, as described above, the defective piece with the provisional defective preliminary mark hole is detected at the predetermined position designated by the customer of the film carrier tape, for example, when the defective preliminary mark hole is detected before shipping, for example, A punching hole is newly formed as a defective display at a predetermined position in a region where the device hole is present. After the final shipment inspection is performed, the electronic component mounting film carrier tape including the defective piece is wound around a reel and shipped to a customer.

  In such a conventional hand-held manual punching device for hand-held, the positioning means in the width direction and the longitudinal direction of the tape is insufficient, and the alignment is performed by visual inspection. Therefore, it is difficult to accurately align and drill a defective preliminary mark hole.

For this reason, the position where the defective preliminary mark hole is drilled may be shifted by about ± 1.2 mm, and the defective preliminary mark hole is drilled in the defective piece. As a result, a misregistration piece that is not recognized as an error will be formed. As a result, the misalignment defective piece is erroneously determined as a normal piece, and a normal defect display is not provided at a predetermined position designated by the customer, which may cause a problem in quality assurance.
Japanese Patent Laid-Open No. 08-47873

  In view of such a situation, the present invention can accurately align the position in the width direction and the position in the longitudinal direction with respect to the defective piece of the electronic component mounting film carrier tape in which the defect is detected. For example, it is possible to cope with either the position passing through the center of the sprocket hole or the intermediate position between the sprocket hole and the adjacent sprocket hole, and a defective preliminary mark hole at the correct position. An object of the present invention is to provide a punching that can be perforated and a positioning adjustment device thereof.

  The attachment hole 60 in the central portion of the film regulating plates 16a and 16b is attached to the drilling reference hole 45 of the flat main frame 14. That is, the positions of the pin members 62 and 62 with respect to the flat main frame 14 are uniquely determined depending on which hole of the four reference holes 45 the film restricting plates 16a and 16b are attached to.

Each component of the positioning adjustment according to the present embodiment is configured as described above. Hereinafter, the positioning adjustment in the case of actually making a hole will be described.
First, the electronic component mounting film carrier tape T has, for example, three types having a width K of 35 mm, 48 mm, and 70 mm. Further, there are two positions for providing the defective preliminary mark hole 70 as shown in FIGS. 7 (A) and 7 (B). That is, although the position on the axis passing through the middle of the tape width K is common, the position where the defective preliminary mark hole of the tape T is formed is, for example, as shown in FIG. Furthermore, it is assumed that either the intermediate position between the sprocket hole 50a and the adjacent sprocket hole 50a or the position passing through the center of the sprocket hole 50a as shown in FIG.

  The defective preliminary mark hole 70 in the tape T shown in FIGS. 7A and 7B is formed at the drilling reference hole 45, the first pin insertion hole 50A, and the second pin insertion hole 50B. The position of the defective preliminary mark hole can be changed to an arbitrary position by changing the position of.

When the tape width K and the position where the defective preliminary mark hole 70 is to be opened are determined, preparation for attaching the film regulating plate 16 is performed before the hole is opened.
Now, assume that the tape width K is 35 mm, and the position where the defective preliminary mark hole 70 is opened is an intermediate position between the sprocket hole 50a and the adjacent sprocket hole 50a (position in FIG. 7A).

In this case, the shorter film regulating plate 16b is used. Then, as shown in FIG. 11, the film restricting plate 16b is first disposed on the back side of the main frame 14, and the screw member 64 is inserted into the mounting hole 60 so that the tip of the screw member 64 is connected to the front end of FIG. As shown to (A), it is screwed together in the drilling reference hole 48b of the flat main frame 14. At this time, the tip of the screw member 64 does not protrude from the upper surface of the flat main frame 14. Therefore, even if the tape T is placed on the flat main frame 14, the tip of the screw member 64 does not damage the tape T.

  When the screw member 64 is inserted into the perforated reference hole 48b, the two pin members 62 and 62 formed on the substantially U-shaped film restricting plate 16b become straight as shown in FIGS. 6 and 8A. It is arranged at the intersection of the DD line and the H row and at the intersection of the straight line DD and the J row. And these pin members 62 and 62 pass through the hole of the intersection, and are projected on the flat main frame 14.

After setting the film regulating plate 16b in this way, the sprocket holes 50a, 50a of the tape T are inserted into the pin members 62, 62 from the right side of the figure. Thereafter, if a punching operation is performed, a desired defective preliminary mark hole 70 can be formed at the position shown in FIG.

When the tape width is 48 mm, the short film regulating plate 16b is used as in the case of the 35 mm width tape.
That is, when the defective preliminary mark hole 70 having a tape width of 48 mm is provided at an intermediate position between the sprocket hole 50a and the adjacent sprocket hole 50a, the film restricting plate 16b is formed as shown in FIG. Attach to. At this time, the pin members 62 and 62 are disposed at the intersection of the straight line EE and the H row and the intersection of the straight line EE and the J row. After setting the film regulating plate 16b in this way, the sprocket holes 50a, 50a of the tape T are inserted into the pin members 62, 62. Thereafter, if a punching operation is performed, a desired defective preliminary mark hole 70 can be formed at an intermediate position between the sprocket holes 50a and 50a shown in FIG.

Similarly, in the case where the defective preliminary mark hole 70 is provided at a position passing through the center of the sprocket hole 50a on the tape T having a width of 48 mm, the attachment hole 60 of the film regulating plate 16b is attached to the drilling reference hole 46a.
