(9) Referring to FIG. 1A, FIG. 1B, and FIG. 1C at the same time, in the present embodiment, a mold separation device 100 includes a carrying mechanism 110 (such as a carrying stage), a scraping mechanism 120, and two separation mechanisms 130. The carrying mechanism 110 is adapted to carry a first mold 10 and a second mold 20 bonded to the first mold 10. The scraping mechanism 120 is disposed at an edge S1 of the carrying mechanism 110 and is adapted to scrape off a spilled glue 30 produced when the first mold 10 is bonded to the second mold 20 (refer to FIG. 3A and FIG. 3B). The separation mechanisms 130 are disposed at the edge S1 of the carrying mechanism 110 and are located on two opposite sides of the scraping mechanism 120. The separation mechanisms 130 are adapted to pull open the first mold 10 and the second mold 20 so that the first mold 10 and the second mold 20 are separated from each other (refer to FIG. 3C, FIG. 3D, and FIG. 3E).

(10) In detail, the mold separation device 100 of the present embodiment is adapted to separate the first mold 10 and the second mold 20, wherein a material of the first mold 10 is, for example, nickel, and the first mold 10 may be regarded as a master mold, and a material of the second mold 20 is, for example, quartz, and the second mold 20 may be regarded as a sub-mold. As shown in FIG. 3A, a thickness T1 of the first mold 10 in the present embodiment is embodied as smaller than a thickness T2 of the second mold 20, wherein the thickness T1 of the first mold 10 is, for example, 3 mm, and the thickness T2 of the second mold 20 is, for example, 9 mm, but the invention is not limited hereto. Herein, the second mold 20 includes an indented portion 24 indented towards the first mold 10 to define an indented space S with the first mold 10, and the spilled glue 30 produced when the first mold 10 is bonded to the second mold 20 is located in the indented space S.

(11) Referring to FIG. 1A, FIG. 1B, and FIG. 1C again, the mold separation device 100 of the present embodiment further includes a working platform 140, wherein the working platform 140 includes a platform surface 142, an accommodating recess 144, and a spin table 146. A height difference H exists between a bottom surface 145 of the accommodating recess 144 and the platform surface 142, and the spin table 146 is located on the platform surface 142. The carrying mechanism 110 is assembled on the spin table 146, the scraping mechanism 120 is located in the accommodating recess 144, and the separation mechanisms 130 are assembled on the platform surface 142.

(12) As shown in FIG. 1A and FIG. 1B, the carrying mechanism 110 is provided to carry the first mold 10 and the second mold 20 adhered to each other, wherein the carrying mechanism 110 fixes the first mold 10 on itself through buckle members 40. Herein, the carrying mechanism 110 is, for example, a carrying mechanism having a vacuum-pumping function for further positioning the first mold 10 and the second mold 20 thereon on the carrying mechanism 110. Moreover, since the carrying mechanism 110 is assembled on the spin table 146 of the working platform 140, the spin table 146 can be spun to simultaneously spin the carrying mechanism 110 and the first mold 10 and the second mold 20 carried on the carrying mechanism 110. Herein, a method of spinning the spin table 146 involves, for example, manually spinning or spinning the spin table 146 through automatic control of a computer program, both of which fall into the scope to be protected by the invention.

(13) As shown in FIG. 1C, the scraping mechanism 120 of the present embodiment includes a blade tool 122 and an adjustment base 124. The adjustment base 124 includes a distance controlling member 125, an angle controlling member 127, and a height controlling member 129. The blade tool 122 is disposed on the adjustment base 124. A distance between the blade tool 122 and the spilled glue 30 is adjusted by the distance controlling member 125. A blade angle of the blade tool 122 is adjusted by the angle controlling member 127. A blade height of the blade tool 122 is adjusted by the height controlling member 129. In other words, a user may use the distance controlling member 125, the angle controlling member 127, and the height controlling member 129 to adjust cutting depths and angles of the blade tool 122 to prevent damage to the first mold 10 and the second mold 20.

(14) Moreover, referring to FIG. 1B and FIG. 1C, each of the separation mechanisms 130 of the present embodiment includes a first separation part 132, a second separation part 134, and a pull controlling member 136. The first separation part 132 and the second separation part 134 are disposed on the pull controlling member 136, and the second separation part 134 is adapted to be moved relatively to the first separation part 132 by a vertical distance D through the pull controlling member 136 (refer to FIG. 3D). Preferably, the two separation mechanisms 130 are arranged to have an included angle of 70° (calculated based on central axis lines of the separation mechanisms 130) for the most desirable force applying range, but the invention is not limited hereto.

(15) In addition, referring to FIG. 1A, FIG. 1B, and FIG. 1C again, the mold separation device 100 of the present embodiment further includes a blocking plate 150 assembled on the platform surface 142 of the working platform 140. The blocking plate 150 is located at another edge S2 of the carrying mechanism 110 opposite to the edge S1 and is configured to abut edges of the first mold 10 and the second mold 20 to protect the first mold 10 and the second mold 20. Herein, the blocking plate 150 is, for example, fixed on the platform surface 142 through two locking members 155, but the invention is not limited hereto.

(16) Moreover, the mold separation device 100 of the present embodiment further includes a vacuum on button 160 and a vacuum off button 170. The vacuum on button 160 and the vacuum off button 170 are both disposed on the working platform 140 and are located on the platform surface 142, wherein the vacuum on button 160 and the vacuum off button 170 are both electrically connected to the carrying mechanism 110 to thereby provide a vacuum adsorption force or remove the vacuum adsorption force.

(17) Referring to both FIG. 1A and FIG. 2, a mold separation method of an embodiment of the invention includes the following steps. First, in step S10, a mold separation device 100 is provided, wherein the mold separation device 100 includes a carrying mechanism 110, a scraping mechanism 120, and separation mechanisms 130. The scraping mechanism 120 is disposed at an edge S1 of the carrying mechanism 110, and the separation mechanisms 130 are disposed at the edge S1 of the carrying mechanism 110 and are located on two opposite sides of the scraping mechanism 120.

(18) Then, in step S20, a first mold 10 and a second mold 20 bonded to the first mold 10 are placed on the carrying mechanism 110, and the first mold 10 is fixed on the carrying mechanism 110 through buckle members 40. Next, a vacuum on button 160 is pressed to generate a vacuum adsorption force between the first mold 10 and the carrying mechanism 110 to further position the first mold 10 and the second mold 20 on the carrying mechanism 110.

(19) Afterwards, referring to FIG. 1A and FIG. 1C, a blocking plate 150 is assembled on a platform surface 142 of a working platform 140, wherein the blocking plate 150 is located at another edge S2 of the carrying mechanism 110 opposite to the edge S1 and is configured to abut and protect edges of the first mold 10 and the second mold 20. Herein, the blocking plate 150 is, for example, fixed at its position through locking members 155, but the invention is not limited hereto.

(20) Then, referring to FIG. 2, FIG. 3A, and FIG. 3B, in step S30, the scraping mechanism 120 is caused to scrape off a spilled glue 30 produced when the first mold 10 is bonded to the second mold 20. In detail, first, the scraping mechanism 120 is moved close to the spilled glue 30 produced when the first mold 10 is bonded to the second mold 20. Then, a spin table 146 (refer to FIG. 1B) of the working platform 140 is spun to spin the carrying mechanism 110, the first mold 10, and the second mold 20 through the spin table 146 to cause the scraping mechanism 120 to scrape off the spilled glue 30 produced when the first mold 10 is bonded to the second mold 20. In other words, the scraping mechanism 120 scrapes off the spilled glue 30 surrounding entire circles of the first mold 10 and the second mold 20.

(21) Afterwards, referring to FIG. 2 again, in step S40, after the spilled glue 30 is scraped off, the separation mechanisms 130 are caused to pull open the first mold 10 and the second mold 20 so that the first mold 10 and the second mold 20 are separated from each other. In detail, referring to FIG. 3C, first, the separation mechanisms 130 are moved close to the first mold 10 and the second mold 20 on the carrying mechanism 110. Next, referring to FIG. 3D, a first separation part 132 of each of the separation mechanisms 130 is caused to abut an upper surface 12 of the first mold 10. Then, each of pull controlling members 136 is adjusted to move each of second separation parts 134 relatively to the first separation parts 132 by a vertical distance D to abut a lower surface 22 of the second mold 20. Afterwards, referring to FIG. 3E, each of the pull controlling members 136 is constantly adjusted to constantly vertically move each of the second separation parts 134 relatively to the first separation parts 132 to pull open the first mold 10 and the second mold 20 so that the first mold 10 and the second mold 20 are separated from each other.

(22) Lastly, after the separation mechanisms 130 are caused to pull open the first mold 10 and the second mold 20, locking members 155 are unlocked to remove the blocking plate 150, and a vacuum off button 170 is pressed to remove the vacuum adsorption force between the first mold 10 and the carrying mechanism 110. At this moment, the mold separation device 100 has separated the first mold 10 and the second mold 20.

(23) In summary of the above, the mold separation device of the embodiments of the invention includes the scraping mechanism and the separation mechanisms. The scraping mechanism first scrapes off the spilled glue produced when the first mold is bonded to the second mold, and then the separation mechanisms pull open the first mold and the second mold so that the first mold and the second mold are separated from each other. Separating the first mold and the second mold through the mold separation device of the embodiments of the invention prevents damage to the master mold and the sub-mold and the issue of uneven glue in a subsequent glue coating process resulting from inserting the blade tool between the master mold and the sub-mold as conventionally required.

(24) Although the invention is disclosed as the embodiments above, the embodiments are not meant to limit the invention. Any person skilled in the art may make slight modifications and variations without departing from the spirit and scope of the invention. Therefore, the protection scope of the invention shall be defined by the claims attached below.
