The following examples are intended to illustrate the novel aspects of the present invention in more detail, but are not intended to limit the scope of the present invention in any way.
Referring to fig. 1, fig. 1 is a schematic diagram illustrating an operation of a system for manufacturing a light reflecting module of a light emitting keyboard according to an embodiment of the present invention.
The novel manufacturing system is suitable for manufacturing the reflective module of the light-emitting keyboard, in other words, the novel manufacturing system is used for manufacturing the reflective module with the reflective sheet R, the light guide sheet G and the shielding sheet S, but the novel manufacturing system is not limited thereto.
The novel manufacturing system comprises a first receiving device I1, a second receiving device I2, a third receiving device I3, a first material pasting device A1 and a second material pasting device A2. The first material pasting equipment A1 is adjacently arranged on the first receiving equipment I1 and the second receiving equipment I2; the second pasting device A2 is adjacently arranged on the first pasting device A1 and the third receiving device I3.
Please refer to fig. 1 and fig. 2 together, wherein fig. 2 is a schematic diagram illustrating an operation of the first receiving apparatus I1 according to an embodiment of the present invention. The first receiving apparatus I1 disclosed in fig. 2 includes a first punch I11 and a first stripping roller I12. The first receiving apparatus I1 receives the tape of the reflective sheet R having the reflective sheet R, and forms a first penetration hole H1 penetrating the reflective sheet R at the reflective sheet R.
In detail, the reflective sheet tape includes a reflective sheet R, and a first upper protective layer R1 and a first lower protective layer R2 covering both sides of the reflective sheet R. The cutter of the first punch I11 of the first receiving apparatus I1 punches the first upper shield layer R1 and the reflective sheet R to form a first through hole H1 in the reflective sheet R. The first through hole H1 shown in fig. 1 and 2 is only an exemplary illustration, and the first through hole H1 may be a plurality of through holes, which should not be construed as a limitation to the present invention.
With continued reference to fig. 1 and 2, after the reflector R forms the first through hole H1, the first stripping roller I12 of the first receiving apparatus I1 strips the first lower shielding layer R2 from the reflector R, thereby removing the waste remaining in the first through hole R1 when the first upper shielding layer R1 and the reflector R are punched.
Please refer to fig. 1 and fig. 3A together, wherein fig. 3A is a schematic diagram illustrating an operation of the second receiving apparatus I2 according to an embodiment of the present invention. The second receiving apparatus I2 disclosed in fig. 3A receives the light guiding sheet strip having the light guiding sheet G, and a second penetrating hole H2 is formed in the light guiding sheet G to penetrate the light guiding sheet G.
Specifically, the light guide sheet tape includes a light guide sheet G, and a first protection layer G1 and a second protection layer G2 covering two different sides of the light guide sheet G. When the light guide sheet G for manufacturing the reflective module is obtained, the material of the first protective layer G1 and the second protective layer G2 covering both sides thereof is usually Polyethylene (PE), but the material property (e.g., ductility) of the PE may cause the Polyethylene to be broken during the drawing process, thereby affecting the manufacturing process of the reflective module of the light-emitting keyboard. Therefore, the second receiving apparatus I2 according to the present invention preferably includes a second stripping roller I21 and a third stripping roller I22 for stripping the first protective layer G1 and the second protective layer G2 from the light guiding sheet G, respectively, so as to replace the material of the protective layer covering the light guiding sheet G with a more ductile material.
After the first protective layer G1 and the second protective layer G2 are peeled off, the first feeding roller I23 of the second receiving apparatus I2 covers the first releasing layer G3 on one side of the light guiding sheet G, and the second feeding roller I24 of the second receiving apparatus I2 covers the second releasing layer G4 on the first releasing layer G3 (i.e., the first releasing layer G3 is located between the light guiding sheet G and the second releasing layer G4). The material of the first release layer G3 and the second release layer G4 is preferably polyethylene terephthalate (PET), but the present invention is not limited thereto.
Next, the cutter of the second punch I25 of the second receiving apparatus I2 punches the light guiding sheet G and the first release film layer G3 to form a second through hole H2 in the light guiding sheet G.
Please refer to fig. 3A and fig. 3B together, wherein fig. 3B is a top view illustrating an operation of the first pressure reducing device I26 of the second receiving device I2 according to an embodiment of the present invention.
The first chamfering unit I26 of the second receiving unit I2 is configured to chamfer the light guide sheet G, the first release film layer G3, and the second release film layer G4 in such a manner as to align with the outer frame of the reflective sheet R, and after chamfering, the long sides of the light guide sheet G on the opposite sides are aligned with the long sides of the reflective sheet R on the opposite sides.
In the embodiment shown in fig. 3A, the second punch I25 is disposed before the first reducing device I26, that is, if the second punch I25 is disposed before the first reducing device I26 in terms of operation flow, but the second punch I25 may also be disposed/operated after the first reducing device I26, which is not limited by the invention.
With continued reference to fig. 3A, after the light guide sheet G and the first stripping layer G3 are punched and the light guide sheet G is cut into desired shapes, the fourth stripping roller I27 of the second receiving apparatus I2 strips the second stripping layer G4 from the first stripping layer G3. Next, the fifth stripping roller I28 of the second receiving apparatus I2 peels the first stripping layer G3 from the light guiding sheet G, thereby removing waste remaining in the second through hole H2 when the first stripping layer G3 and the light guiding sheet G are punched together.
Referring to fig. 1 and fig. 4, fig. 4 is a schematic diagram illustrating an operation of a first material sticking apparatus a1 according to an embodiment of the present invention.
When the first receiving apparatus I1 is operated and outputs the reflective sheet R and the first upper protective layer R1 having the first through hole H1, and the second receiving apparatus I2 is operated and outputs the light guiding sheet G having the second through hole H2, the first pasting apparatus a1 according to the present invention receives the reflective sheet R and the first upper protective layer R1 output by the first receiving apparatus I1, and receives the light guiding sheet G output by the second receiving apparatus I2, and pastes the side of the reflective sheet R away from the first upper protective layer R1 to the light guiding sheet G. In detail, the first pasting device a1 aligns the first through hole H1 and the second through hole H2, so that the first through hole H1 and the second through hole H2 can be aligned with each other when the reflection sheet R is pasted on the light guide sheet G.
Referring to fig. 4, the first pasting machine a1 according to the present invention preferably has a first pasting roller a11 and a second pasting roller a12 for respectively applying pressure to the reflective sheet R and the light guide sheet G to paste the reflective sheet R and the light guide sheet G to each other. According to the first pasting device a1 of the present invention, if one of the reflective sheet R and the light guide sheet G is disposed on a fixed platform (e.g., a belt of a conveyor), the first pasting device a1 may have only one pasting roller to apply pressure to the reflective sheet R and the light guide sheet G to make them adhere to each other.
Please refer to fig. 1 and fig. 5A together, wherein fig. 5A is a schematic diagram of a third receiving apparatus I3 according to an embodiment of the present invention. The third receiving apparatus I3 disclosed in fig. 5A receives the strip of shielding sheets S and forms a third penetrating hole H3 penetrating the shielding sheets S in the shielding sheets S.
In detail, the shielding sheet strip includes a shielding sheet S and a second upper protective layer S1 and a second lower protective layer S2 covering both sides of the shielding sheet S. When the shielding sheet S for manufacturing the reflective module is obtained, the second upper protective layer S1 and the second lower protective layer S2 covering both sides thereof are typically polyethylene. Therefore, similar to the second receiving apparatus I2 shown in fig. 3A, the third receiving apparatus I3 of the present invention preferably includes a sixth stripping roller I31 and a seventh stripping roller I32 for stripping the second upper shielding layer S1 and the second lower shielding layer S2 from the shielding sheet S to replace the material covering the shielding sheet S, so as to subsequently replace the material covering the shielding layer of the shielding sheet S with a more ductile material.
With continued reference to fig. 5A, after the second upper shielding layer S1 and the second lower shielding layer S2 are stripped, the third feeding roller I33 and the fourth feeding roller I34 of the third receiving apparatus I3 cover the upper stripping layer S3 and the lower stripping layer S4 on the two opposite sides of the shielding sheet S. The upper release layer S3 and the lower release layer S4 are preferably Polyethylene Terephthalate (PET), but the present invention is not limited thereto.
When the shielding sheet S is obtained, the second upper shielding layer S1 and the second lower shielding layer S2 covering the two different sides of the shielding sheet S are made of a material with good ductility (for example, PET), the third receiving device I3 may be implemented without including the sixth stripping roller I31, the seventh stripping roller I32, the third feeding roller I33 and the fourth feeding roller I34.
Next, the cutter of the third punch I35 of the third receiving apparatus I3 punches the shield sheet S and the lower release layer S4 to form a third through hole H3 in the shield sheet S.
Please refer to fig. 5A and fig. 5B together, wherein fig. 5B is a top view illustrating an operation of the second pressure reducing device I36 of the third receiving device I3 according to an embodiment of the present invention. The second pressure reducing device I36 is configured to press the shielding sheet S, the upper release layer S3, and the lower release layer S4 against the outer frame of the reflection sheet R so that the long sides of the shielding sheet S are aligned with the long sides of the reflection sheet R shown in fig. 1 and 2.
The third punch I35 shown in fig. 5A is disposed before the second reducing device I36, but the third punch I35 may be disposed after the second reducing device I36, which should not be construed as a limitation of the present invention.
With continued reference to fig. 5A, after the punching of the shielding sheet S and the lower delaminating layer S4 and the chopping of the shielding sheet S, the upper delaminating layer S3 and the lower delaminating layer S4 are completed, the eighth stripping roller I37 of the third receiving apparatus I3 peels the upper delaminating layer S3 from the shielding sheet S, and thereby removes the scraps remaining in the third through hole H3 while punching the shielding sheet S and the lower delaminating layer S4 together.
Referring back to fig. 1 and fig. 6, fig. 6 is a schematic diagram illustrating an operation of a second material sticking apparatus a2 according to an embodiment of the present invention. After the first pasting device a1 finishes pasting and outputting the reflective sheet R and the light guide sheet G, and the third receiving device I3 outputs the shielding sheet S with the third through hole H3 and the lower release layer S4, the second pasting device a2 aligns the second through hole H2 and the third through hole H3, so as to accurately paste the shielding sheet S on the side of the light guide sheet G away from the reflective sheet R. The second pasting device a2 preferably has a third pasting roller a21 and a fourth pasting roller a22, and the second pasting device a2 is similar to the first pasting device a 1; the third pasting roller a21 and the fourth pasting roller a22 are similar to the first pasting roller a11 and the second pasting roller a12 of fig. 4, so the details of the arrangement and operation of the second pasting device a2, the third pasting roller a21 and the fourth pasting roller a22 are not repeated herein.
In summary, according to the manufacturing system of the reflective module of the light-emitting keyboard of the present invention, a Roll-to-Roll (Roll-to-Roll) manufacturing process can be implemented, so that the conventional manual method for positioning, assembling and detecting the reflective sheet, the light guide sheet and the shielding sheet can be avoided, thereby saving the labor cost and reducing the probability of human error.
