Description

  The present invention relates to a protective paper take-up core for taking up a protective paper peeled off from an adhesive film sheet.

  Among the semiconductor manufacturing processes, there is a film sheet pasting process in which an adhesive film sheet is stretched over a ring frame, and a semiconductor wafer is arranged and integrated on the adhesive film sheet. At this time, since the protective paper is peeled off from the adhesive film sheet, the protective paper is wound around the protective paper winding core and collected. As a prior art example in which such a protective paper take-up core is used, for example, there is a tape applicator described in JP-A-2002-176011. This tape applicator is equipped with a separator take-up roller (equivalent to a protective paper take-up core) and peels off a separator (equivalent to protective paper) for protecting the adhesive surface of the film from an unused tape (equivalent to an adhesive film sheet). However, the unused tape is fed out, and at the same time as the feeding out, the separator is wound around the separator winding roller.

The driving side fitting portion 15 is pressed to the cylindrical portion 151 at the end of the protective paper winding core 100 to complete the mounting.

Next, the winding operation of the protective paper winding device 43 will be described.
4A and 4B are explanatory diagrams of the use of the protective paper winding core 100. FIG. 4A is an explanatory diagram of attachment of the protective paper, and FIG. 4B is an explanatory diagram of removal of the protective paper.
The film sheet supply unit 42 shown in FIG. 2A feeds the film sheet and supplies the film sheet. At this time, the protective paper is peeled off from the adhesive surface of the film sheet, and the protective paper take-up device 43 causes the protective paper take-up core 100 to take up the protective paper.
Before starting the winding, first, as shown in FIG. 4 (a), the protective paper 60 is inserted and penetrated into the gap portion 140 so that the front end is protruded to the opposite side, and the protective paper 60 is wound to hold the front end. The leading end of 60 is wound (pressed) and held to form a winding start, and the protective paper 60 is fixed to the protective paper winding core 100. Since the start of winding is configured as described above, no fixed tape is required.

  Subsequently, as shown in FIG. 2A, when the driving unit 41 transmits the driving force, the film sheet supply unit 42 drives the protective paper take-up device 43 while feeding the film sheet to wind the protective paper 60. A take is made. Although the film sheet supply unit 42 and the protective paper take-up device 43 are operated in synchronization, even if an overrun of the protective paper take-up core 100 occurs, the driving side holding unit 10 is driven with respect to the protective paper take-up core 100. Overrun is absorbed by the side fitting part 15 slipping.

  Next, the removal of the protective paper 60 from the protective paper winding core 100 that characterizes the present invention will be described. When all the film sheets are unwound from the film sheet supply unit 42 and the winding by the protective paper winding device 43 is finished, the protective paper 60 is wound around the protective paper winding core 100 as shown in FIG. It is in the state where the shape winding part was formed. In this state, the protective paper take-up core 100 is removed from the protective paper take-up device 43 and then the protective paper 60 is removed. However, it is not easy to remove the protective paper 60 tightly wound around the protective paper take-up core 100.

  Therefore, as shown in FIG. 1 (i), the first divided body 170 and the second divided body 180 are moved in opposite directions to separate the distal end portions 154 and 164 from the connection portions 152 and 162 to separate them. As shown in FIG. 4B, when the first long body 150 and the second long body 160 are moved in the direction of the arrow c so as to reduce the gap 140, a sufficient space is formed and the first long body is formed. The body 150 and the second long body 160 can be pulled out from the scroll-shaped winding portion of the protective paper 60. The protective paper winding core 100 can be removed from the protective paper 60 by removing the two sets of the first divided body 170 and the second divided body 180 that have been disassembled from the protective paper 60. Furthermore, since the tip of the protective paper 60 is not tape-fixed as described above, the protective paper 60 can be removed while still being a scroll-like winding part.

  According to such a protective paper take-up core 100, the protective paper 60 can be easily removed in the form of a scroll-like winding part only by a simple pulling operation, thereby simplifying the operation. Furthermore, since the protective paper 60 remaining after the protective paper take-up core 100 is removed is a roll-shaped winding portion, the volume of waste is greatly reduced.

The gap 240 is formed between the notches 256 and 266 when the first long body 250 and the second long body 260 are combined as shown in FIG. As shown in c), the cylindrical core body 210 is formed at two opposing positions. The protective paper is fixed to the protective paper take-up core 200 by rotating the gaps 240 so that the front ends of the protective paper are pressed while the protective paper is inserted.
The use of the protective paper take-up core 200 is the same as in the previous embodiment, and is sandwiched between the driving side fitting portion 15 of the driving side holding portion 10 and the driven side fitting portion 27 of the driven side holding portion 20 described above. Therefore, even if the first fixing part 220 and the second fixing part 230 are not fixed to the core body 210 and are merely fitted, they can be installed in the protective paper winding device as described above. .

According to such a protective paper take-up core 200, the protective paper 60 can be easily removed only by a simple pulling operation, thereby simplifying the operation. Furthermore, the protective paper 60 remaining after the protective paper take-up core 100 is removed is in the form of a scroll, realizing a significant volume reduction as waste.
Furthermore, the first fixing part 220 and the second fixing part 230 are simplified as simple ring bodies (elastic bodies such as rubber bands, O-rings, metal rings, fastening bands), and it is only necessary to purchase inexpensive commercial products. Well, the manufacturing cost can be reduced.
Further, the first and second fixing portions of the cylindrical body described above with reference to FIG. 1 may be adopted and fitted into the core body 210.

The disassembled first divided body 680 and second divided body 690 can be removed from the protective paper 60, and the protective paper take-up core 600 can be removed from the wound portion of the protective paper 60.

According to such a protective paper take-up core 600, the protective paper 60 can be easily removed only by a simple pulling operation, thereby simplifying the operation. Further, the protective paper 60 remaining after the protective paper take-up core 600 is removed has a roll shape, and the volume of waste is greatly reduced.
Moreover, since the first long body and the second long body have an arc shape in the previous form, there is a possibility that the leading end of the protective paper may be caught inside the arc when the protective paper is inserted into the gap portion. The first long body 650 and the second long body 660 are manufactured from round bars, and the gap portion 640 has a wide drum shape at the entrance, so that the front end of the protective paper 60 can be easily passed.

The multiple forms of the protective paper winding cores 100 to 600 of the present invention have been described above.
In any of these forms, the work efficiency can be greatly increased by facilitating the removal work of the protective paper wound with simple ideas.
Furthermore, the volume of the waste can be reduced and the disposal work can be facilitated by using the removed protective paper as a scroll.
