That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model discloses an automated cutting and bonding device for motherboard Mylar, comprising a support plate 1, a coating shell 2, a Mylar sheet 3, an extrusion frame 4, and a cutting frame 6. The coating shell 2 is disposed inside the support plate 1, and a crossbar is installed in the middle of the coating shell 2. The crossbar and the coating shell 2 form a coating groove 20 that are interconnected. The Mylar sheet 3 is placed on the coating shell 2. The cutting frame 6 is disposed inside the extrusion frame 4 and is horizontally opposite to the coating shell 2. A rubber frame 5 is installed inside the extrusion frame 4. An air extraction shell 7 is disposed inside the cutting frame 6. Multiple suction cups 17 communicating with the inner cavity of the air extraction shell 7 are installed on the side of the air extraction shell 7 facing the coating shell 2. The inner side of the support plate 1 is provided with a positioning groove 14 that matches the length and width of the motherboard at the position opposite the coating shell 2.

[0022] In this embodiment, the support plate 1 is arranged in a "U" shape. A first cylinder 13 is installed on one vertical end of the support plate 1. The piston rod of the first cylinder 13 passes through the support plate 1 and is fixedly connected to the paint shell 2. Multiple injection pipes 15 connected to the paint tank 20 are installed on the side of the paint shell 2 away from the Mylar film 3. The other end of the injection pipe 15 is connected to a metering pump through a hose.

[0023] In this embodiment, the length and width inside the rubber frame 5 are greater than the length and width of the coating shell 2. A first fixing plate 10 is installed at one end of the rubber frame 5. A second cylinder 12 is installed on the top of the support plate 1 directly opposite the first fixing plate 10 via a bracket. The piston rod of the second cylinder 12 is installed on the first fixing plate 10.

[0024] In this embodiment, the cutting frame 6 has a sharp cutting part at one end facing the coating shell 2, and a second fixing plate 9 is installed at one end of the cutting frame 6. The top of the support plate 1 has a notch directly opposite the second fixing plate 9. A third cylinder 11 is installed on the notch, and the piston rod of the third cylinder 11 passes through the notch and is installed on the second fixing plate 9.

[0025] In this embodiment, a fourth cylinder 8 is installed on the top of the support plate 1, and the piston rod of the fourth cylinder 8 passes through the support plate 1 and is installed on the suction shell 7.

[0026] In this embodiment, an air extraction pipe 16 is installed on the other side of the air extraction shell 7. The other end of the air extraction pipe 16 is connected to a vacuum adsorption pump via a hose. An exhaust pipe 18 is also installed on the other side of the air extraction shell 7. A solenoid valve 19 is installed on the exhaust pipe 18. After the bonding is completed, the solenoid valve can be opened to allow the gas inside the air extraction pump to be discharged, causing the suction cup to lose its suction force, thereby separating it from the Mylar sheet.

[0027] In use, the Mylar sheet is placed on the paint, and the main board is placed in the positioning slot. Then, the second cylinder is activated, causing the piston rod of the second cylinder to extend and push the extrusion frame and rubber frame to descend. Since the length and width of the inner cavity of the rubber frame are slightly larger than the length and width of the paint shell, during the descent, the friction between the rubber frame and the Mylar sheet causes the excess four sides of the Mylar sheet to bend downward and fit tightly against the side of the paint shell. During the descent, the friction also causes the Mylar sheet to be pulled outward. After the extrusion frame descends to a certain extent;

[0028] Then start the fourth cylinder, which will extend the piston rod of the fourth cylinder and drive the suction port to descend until the suction cup makes multiple points of contact with the Mylar film. After the vacuum adsorption pump is started, the suction force generated will enable the suction cup to adsorb and fix the Mylar film.

[0029] Next, start the metering pump. The metering pump can inject the glue into the paint tank. As the amount of glue increases, the glue will rise in the paint tank until it comes into contact with the Mylar sheet, so that the glue can be applied to the four sides and the middle of the Mylar sheet to ensure the subsequent bonding strength.

[0030] Then, the second cylinder is activated, causing its piston rod to extend and lower the cutting frame. The lowered cutting frame cuts off the excess Mylar sheet. After cutting, the extrusion frame and the cutting frame return to their original positions, and the first cylinder is activated, causing its piston rod to retract and move the coating shell away from below the suction shell. At this point, the fourth cylinder is activated again, causing the adsorbed Mylar sheet to descend and adhere to the main board.

[0031] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
