Abstract

A screen film applicator includes a seat, a positioning member, and a first mechanism, the latter two of which are disposed on the seat. The seat has a track and a positioning portion arranged beside the track. The positioning member is movable with respect to the positioning portion for clamping a communication device. The first mechanism includes a top fixing member disposed on the seat, a moving carriage movable along the track, a bottom fixing member synchronously movable with the moving carriage, and a roller movable with the moving carriage. The top and the bottom fixing members are configured to respectively fix a top releasing film and a bottom releasing film respectively adhered on two opposite sides of a soft screen film. When the moving carriage is moved away from the top fixing member, the roller can gradually press the soft screen film onto the communication device.

Claims

1. A screen film applicator, comprising:

a seat having a track and a positioning portion arranged at one side of the track for positioning a communication device;

a positioning member disposed on the seat, wherein the positioning member is movable with respect to the seat, and the positioning member and the positioning portion are configured to clamp the communication device; and

a first mechanism disposed on the seat for allowing a soft screen film to be adhered onto the communication device, wherein the first mechanism includes;

a top fixing member disposed on the seat, wherein the top fixing member is configured to fix a top releasing film adhered on the soft screen film;

a moving carriage movable along the track of the seat;

a bottom fixing member movable with the moving carriage, wherein the bottom fixing member is configured to fix a bottom releasing film adhered on the soft screen film; and

a roller synchronously movable with the moving carriage, wherein when the moving carriage is moved away from the top fixing member, the roller is configured to gradually press the soft screen film onto the communication device.

2. The screen film applicator as claimed in claim 1, wherein the first mechanism further includes a manipulating bar installed on the moving carriage, and the bottom fixing member is installed on the moving carriage, wherein when the moving carriage is moved away from the top fixing member, the manipulating bar is synchronously moved with the moving carriage and is configured to be pressed toward the seat along the moving carriage.

3. The screen film applicator as claimed in claim 2, wherein the top fixing member includes a plurality of top positioning pillars disposed on the seat and a covering plate pivotally connected to the seat, the top positioning pillars are configured to respectively insert into holes formed on a portion of the top releasing film, and the covering plate and the seat are configured to clamp the portion of the top releasing film.

4. The screen film applicator as claimed in claim 2, wherein an end of the bottom fixing member is connected to the moving seat, and the bottom fixing member includes an elongated rod, a plurality of bottom fixing pillars disposed on the rod, a magnetic block embedded in the rod and arranged between two of the bottom fixing pillars, and a magnetic cover movably connected to the rod, wherein the bottom fixing pillars are configured to respectively insert into holes formed on a portion of the bottom releasing film, and the magnetic cover and the magnetic block are detachably connected to each other for clamping the portion of the bottom releasing film.

5. The screen film applicator as claimed in claim 1, wherein the moving carriage includes a limiting carrier, the limiting carrier has a hole formed on a bottom surface thereof, the seat includes a plurality of positioning balls corresponding in position to the bottom surface of the limiting carrier, the positioning balls are spaced away from each other and are arranged in one row parallel to the bottom surface of the limiting carrier, and the hole of the limiting carrier is configured to selectivity sleeve at one of the positioning balls.

6. The screen film applicator as claimed in claim 1, wherein the positioning member includes a T-shaped shaft disposed on the seat, a reinforcing sheet, a longitudinal linear guideway, and a transversal linear guideway, wherein the reinforcing sheet, the longitudinal linear guideway, and the transversal linear guideway are fastened to the seat, the longitudinal linear guideway and the transversal linear guideway are interconnected to each other, and the reinforcing sheet is fixed to the T-shaped shaft and one of the longitudinal linear guideway and the transversal linear guideway.

7. The screen film applicator as claimed in claim 2, wherein the positioning portion is a concavity recessed on a top surface of the seat, the positioning member includes an L-shaped abutting portion movable in the concavity, and the abutting portion and an inner corner of the concavity are configured to respectively clamp two diagonal corners of the communication device.

8. The screen film applicator as claimed in claim 1, further comprising a second mechanism disposed on the seat for allowing a glass screen film to be adhered onto the communication device, wherein the first mechanism and the second mechanism are not manipulated at the same time, and the second mechanism includes:

a stand disposed on the seat; and

an inhaling member installed on the stand, wherein the inhaling member is manipulatable to suck the glass screen film.

9. The screen film applicator as claimed in claim 8, wherein the stand is movable along the track of the seat, and the inhaling member is synchronously moved with the stand and is configured to be pressed toward the seat along the stand for sucking the glass screen film.

10. The screen film applicator as claimed in claim 8, wherein the second mechanism includes a plurality of positioning pillars disposed on a portion of the seat between the positioning potion and the track, the positioning pillars are arranged in one row, and the positioning pillars are configured to insert into holes formed on a releasing plate adhered to the glass screen film.
