Embodiment

See also Fig. 1, the coat peeling unit 10 that the utility model one preferred embodiment is provided is in order to remove the film 14 on the plate 12, this plate 12 is the Polarizer of a rectangle in present embodiment, and this coat peeling unit 10 includes a bearing platform 20, a slide 30, an adhesive tape 40, a fixture block 50, a waste station 60 and a briquetting 70.

This bearing platform 20 is to use for 12 bearings of this plate, and wherein this film 14 is the tops that are positioned at this plate 12, and this bearing platform 20 can be established most hole or suckers inhaled, and utilizes just plate 12 location of negative pressure.

This slide 30 is to be located at this bearing platform 20 tops horizontally slidingly, this slide 30 is provided with one for section's wheel 32, one contact wheel 33 and rewinding wheel 34, this slide 30 also can displacement between a lower position and a high position, this adhesive tape 40 is to be wound on this applicator wheel 32, and this contact wheel 33 of pile warp and being wound on this rewinding wheel 34, when this slide 30 was positioned at lower position, the adhesive tape 40 on this contact wheel 33 was to paste the film 14 that is butted on this plate 12, as shown in Figure 2; When this slide 30 returned back to the high position, the adhesive tape 40 on this contact wheel 33 can stick the film on the plate 12 14, as shown in Figure 3.When this applicator wheel 32 is rotated with this rewinding wheel 34, the renewable adhesive tape that is wound in outside this contact wheel 33, this moves and carries out at every turn after removing a film 14.

This fixture block 50 is to be slidedly arranged on this slide 30, and this fixture block 50 is to have an erection part 52 and a horizontal portion 54 of stretching is extended by these erection part 52 bottoms, and this fixture block 50 is whole L-shaped.This fixture block 50 can displacement between a clip position and a separation point position, when this fixture block 50 is positioned at the separation point position, as shown in Figure 3, this fixture block 50 is to separate with this contact wheel 33 (and this adhesive tape 40), when this fixture block 50 is positioned at clip position, as shown in Figure 4, this fixture block 50 is to paste and be butted on this contact wheel 33 bottoms with its horizontal portion 54 of stretching, and this adhesive tape 40 is held between this contact wheel 33 and this fixture block 50.This fixture block 50 by the sequence of movement that the separation point position moves to clip position is: move vertically downward, move horizontally again and move vertically upward.

This waste station 60 is the belows that are positioned at these bearing platform 20 sides and are positioned at these slide 30 mobile routes, in order to bearing by the film 14 that removes on the plate 12, this waste station 60 can be driven and lifting, is positioned at a predetermined altitude to keep the end face that is deposited in these waste station 60 upper films 14.This briquetting 70 can be driven displacement between a high position and a lower position, when this briquetting 70 is positioned at lower position, is the film 14 that is pressed against on this waste station 60.

During practical operation, earlier a plate 12 is placed on this bearing platform 20, as shown in Figure 1, then drive this slide 30 and be displaced downwardly to lower position, make these contact wheel 33 outer adhesive tapes 40 paste the film 14 that is butted on this plate 12, as shown in Figure 2, drive then on this slide 30 and move to the high position, one end of this film 14 can be sticked by this adhesive tape 40 and break away from this plate 12, as shown in Figure 3, then driving this fixture block 50 makes it arrive clip position, at this moment, these adhesive tape 40 1 ends will be held between this contact wheel 33 and this fixture block 50, as shown in Figure 4, then drive this slide 30 and make the displacement to the right of its level, as shown in Figure 5, this film 14 will be torn off by these plate 12 surfaces this moment, till complete and these plate 12 disengagings, this slide 30 continues displacement to the right, the film 14 that will be torn off is carried into this waste station 60 tops, as shown in Figure 6, then drives this briquetting 70 and is displaced downwardly to lower position, this film 70 will be pressed against between this briquetting 70 and this waste station 60 this moment, drive this fixture block 50 simultaneously and make it arrive the separation point position, as shown in Figure 7, last, driving this slide 30 continues to move to right, this film 70 can break away from this adhesive tape 40, so constantly carries out, and film 70 will be stacked on this waste station 60, this waste station 60 can be subjected to drive gradually and reduce, and the apical side height of these films 14 is remained unchanged.

Thus, the coat peeling unit 10 that the utility model provides whenever removes the film 14 of a plate 12, only need consume a bit of adhesive tape, obviously reduces the adhesive tape consumption than known structure, can effectively reduce manufacturing cost, in addition, the design of this fixture block 50 can more firmly attach to film 14 on the adhesive tape 40, therefore, adopt the comparatively cheap general adhesive tape of price, can reach effect of the present utility model, so will further cut down finished cost, thereby reach the purpose of this utility model.
