Device and method for pressure-molding anti-overheating csp fluorescent membrane

A device for pressure-molding an anti-overheating CSP fluorescent membrane, comprising a frame (12), a mould pressing device (13), a force measuring device (14), a control device (15), and a feeding device (16), wherein the mould pressing device is disposed in the frame (12), and the force measuring device (14) is disposed at a bottom of the mould pressing device (13);

• the control device (15) and the feeding device (16) are disposed outside the frame (12);
• the force measuring device (14) is implemented by a force sensor and a capture card;
• the feeding device (16) is implemented by a motor screw drive, a pneumatic drive or a hydraulic drive;
• and the control device (15) is implemented by a closed loop servo-control system and an industrial computer;
• the mould pressing device (13) comprises an upper pressing mould, an upper clamp (3), a lower pressing mould, a guide post (4), an elastic supporting structure (10), and a lower clamp (5);
• the upper pressing mould comprises an upper pressing mould body (1) and an upper pressing mould heating device (2);
• the lower pressing mould comprises a lower pressing mould body (6) and a lower pressing mould heating device (7);
• the upper pressing mould heating device (2) is disposed in the upper pressing mould body (1), and heats the upper pressing mould body (1) during pressure-molding;
• and the lower pressing mould heating device (7) is disposed in the lower pressing mould body (6), and heats the lower pressing mould body (6) during pressure-molding;
• the upper clamp (3) is fixed in a lateral surface of the upper pressing mould body (1) close to the lower clamp (5);
• the lower clamp (5) and the lower pressing mould body (6) are connected by the elastic supporting structure (10);
• when the moulds are not clamped, the elastic supporting structure (10) is not subjected to a mould clamping force, and a bottom surface of the lower clamp (5) is separated from an upper surface of the lower pressing mould body (6);
• when the moulds are clamped, the elastic supporting structure (10) is subjected to the mould clamping force, and shrinks and deforms, so that the bottom surface of the lower clamp (5) is contacted with the upper surface of the lower pressing mould body (6);
• and the upper surface of the lower clamp (5) is a smooth surface;
• and
• the upper pressing mould and the lower pressing mould are mounted at the guide post (4), and by means of controlling the feeding device (16), the upper pressing mould or the lower pressing mould moves on the guide post (4) and the clamped or separated moulds are precisely positioned;
• and when the moulds are not clamped, the upper pressing mould and the lower pressing mould are in a separated state.
