Definitions
- the present invention relates to a method and an apparatus for peeling a protective film affixed to a glass substrate surface used for a liquid crystal display or the like.
- a glass substrate used for a liquid crystal display is obtained by cutting out and using a plurality of glass substrates for a single large glass substrate. Due to the recent increase in size, this large glass substrate is transported in a stacked state when it arrives at the factory, and is placed in the manufacturing process. And when using a glass substrate, it takes out one piece from the large-sized glass substrate in the state where a plurality of sheets were stacked. For this reason, a protective film for preventing scratches is attached to the front and back surfaces of each glass substrate, and the protective film is peeled off during processing.
- the present invention has been made in view of the above-mentioned problems of the prior art.
- the consumption power of the adhesive tape, the protective film attached to both sides of the glass substrate can be easily and reliably peeled off.
- An object of the present invention is to provide a film peeling method and apparatus that enables efficient film peeling.
- the adhesive tape cassette unit 28 includes a feed reel 31 and a take-up reel 32 for the adhesive tape 30.
- the adhesive tape 30 fed from the feed reel 31 passes through the guide roller 34, turns to contact with the peeling head 40 where the tape back surface 38 which is not the adhesive surface 36 is slidably contacted, passes through the other guide roller 34, and is then wound up. Wrapped around 32.
- These members are housed in a substantially rectangular plate-shaped case 42, but the peeling head 40 is positioned so that the adhesive surface 36 of the adhesive tape 30 protrudes outside the case 42! / ⁇ The
- the adhesive tape 30 is not attached to the entire length of the protective film 54 and peeled off, it is easy to process.
- the adhesive tape 30 used to peel off the edge of the protective film 54 sticks out slightly from the edge of the protective film 54 and sticks to the edge of the protective film 54. Air enters, is easily lifted, and the protective film 54 is reliably peeled off.
- the area of only the end face part of the peeling head 40 is used, the amount of the adhesive tape 30 used is small, and the cost can be reduced.
- the film peeling apparatus of the present invention is not limited to the above embodiment, and when the film chuck apparatus holds the peeled protective film, the edges located at both ends in the width direction of the glass substrate are Either one of them may be held in addition to what is held at the same time.
- the peeling processing unit may be installed in a series of steps of the glass substrate. It may also be used for peeling off protective films on substrates other than glass substrates.
