Abstract

A mold separation method includes the following steps: providing a mold separation device including a carrying mechanism, a scraping mechanism, and two separation mechanisms, wherein the scraping mechanism is disposed at an edge of the carrying mechanism, and the separation mechanisms are disposed at the edge of the carrying mechanism and are located on two opposite sides of the scraping mechanism; placing a first mold and a second mold bonded to the first mold on the carrying mechanism; causing the scraping mechanism to scrape off a spilled glue produced when the first mold is bonded to the second mold; and after scraping off the spilled glue, causing the separation mechanisms to pull open the first mold and the second mold so that the first mold and the second mold are separated from each other.

First claim

What is claimed is:

1. A mold separation method comprising:
providing a mold separation device, the mold separation device comprising:
a carrying mechanism;
a scraping mechanism disposed at an edge of the carrying mechanism;
two separation mechanisms disposed at the edge of the carrying mechanism and located on two opposite sides of the scraping mechanism, wherein each of the two separation mechanisms comprising a blade tool, and the blade tool is mounted in a fixed position; and
a working platform comprising a platform surface, an accommodating recess, and a spin table, wherein a height difference exists between a bottom surface of the accommodating recess and the platform surface, and the spin table is located on the platform surface;

placing a first mold and a second mold bonded to the first mold on the carrying mechanism;
causing the scraping mechanism to scrape off a spilled glue produced when the first mold is bonded to the second mold; and
after scraping off the spilled glue, causing the separation mechanisms to pull open the first mold and the second mold so that the first mold and the second mold are separated from each other.

2. The mold separation method as recited in claim 1 , wherein the carrying mechanism is assembled on the spin table, the scraping mechanism is located in the accommodating recess, and the separation mechanisms are assembled on the platform surface, the step of causing the scraping mechanism to scrape off the spilled glue produced when the first mold is bonded to the second mold comprising:
moving the scraping mechanism close to the spilled glue produced when the first mold is bonded to the second mold; and
spinning the spin table to spin the carrying mechanism, the first mold, and the second mold through the spin table and cause the scraping mechanism to scrape off the spilled glue produced when the first mold is bonded to the second mold.

3. The mold separation method as recited in claim 1 , wherein the mold separation device further comprises a blocking plate, and after placing the first mold and the second mold bonded to the first mold on the carrying mechanism and before causing the scraping mechanism to scrape off the spilled glue produced when the first mold is bonded to the second mold, the mold separation method further comprises:
assembling the blocking plate on the platform surface, wherein the blocking plate is located at another edge of the carrying mechanism opposite to the edge and is configured to abut edges of the first mold and the second mold.

4. The mold separation method as recited in claim 1 , wherein the mold separation device further comprises a vacuum on button and a vacuum off button, and the vacuum on button and the vacuum off button are disposed on the working platform and are located on the platform surface, the mold separation method further comprising:
pressing the vacuum on button to generate a vacuum adsorption force between the first mold and the carrying mechanism after placing the first mold and the second mold bonded to the first mold on the carrying mechanism and before assembling the blocking plate on the platform surface; and
pressing the vacuum off button to remove the vacuum adsorption force between the first mold and the carrying mechanism after causing the separation mechanisms to pull open the first mold and the second mold.

5. The mold separation method as recited in claim 1 , wherein the scraping mechanism comprises a blade tool and an adjustment base, and the adjustment base comprises a distance controlling member, an angle controlling member, and a height controlling member, the blade tool is disposed on the adjustment base, a distance between the blade tool and the spilled glue is adjusted by the distance controlling member, a blade angle of the blade tool is adjusted by the angle controlling member, and a blade height of the blade tool is adjusted by the height controlling member.

6. The mold separation method as recited in claim 1 , wherein each of the separation mechanisms comprises a first separation part, a second separation part, and a pull controlling member, the first separation part and the second separation part are disposed on the pull controlling member, and the second separation part is adapted to be moved relatively to the first separation part by a vertical distance through the pull controlling member.

7. The mold separation method as recited in claim 6 , wherein the step of causing the separation mechanisms to pull open the first mold and the second mold comprises:
moving the separation mechanisms close to the carrying mechanism;
causing the first separation part of each of the separation mechanisms to abut an upper surface of the first mold;
adjusting each of the pull controlling members to move each of the second separation parts relatively to the first separation parts by a vertical distance to abut a lower surface of the second mold; and
constantly adjusting each of the pull controlling members to constantly vertically move each of the second separation parts relatively to the first separation parts and pull open the first mold and the second mold so that the first mold and the second mold are separated from each other.

8. The mold separation method as recited in claim 1 , wherein a thickness of the first mold is smaller than a thickness of the second mold.

9. The mold separation method as recited in claim 1 , wherein the second mold comprises an indented portion indented towards the first mold to define an indented space with the first mold, and the spilled glue produced when the first mold is bonded to the second mold is located in the indented space.
