[0002] Prepreg, also known as "PP sheet," is one of the primary materials used in multilayer board production. It's primarily composed of resin and reinforcement materials, which can be categorized into fiberglass cloth, paper-based materials, and composite materials. Prepreg used in multilayer printed circuit boards mostly utilizes fiberglass cloth as the reinforcement. Prepreg is a thin sheet of treated fiberglass cloth, impregnated with a resin adhesive, and then heat-treated to bring the resin to its B (semi-solid) stage. It softens under heat and pressure and solidifies upon cooling.

[0003] After searching, it was found that the Chinese patent with publication number CN216884830U discloses a device for heating semi-cured sheets. This utility model can simultaneously drive the movement of the first electric heater, the second electric heater and the third electric heater by adjusting the rotation of the screw rod, and can heat the trays on the first bracket, the second bracket and the third bracket at the same time, thereby improving the heating uniformity of multiple groups of trays.

[0004] After the prepreg is heated, the temperature in the oven is still relatively high, and the tray carrying the prepreg is thermally conductive. During this process, people are prone to burns when operating, which needs to be improved. Utility Model Content

A C-shaped block 3 is provided in the inner cavity of the device body 2, and the C-shaped blocks 3 are arranged in a symmetrical multi-layer arrangement, and a tray 4 is inserted between two opposite C-shaped blocks 3.

[0032] like Figure 2 、 Figure 3 As shown, a moving rod 5 is symmetrically arranged on the back of the tray 4, and a limiting plate 6 is connected to the side of the moving rod 5 away from the tray 4, and the limiting plate 6 is slidably connected to the device body 2, and an elastic member 7 is connected between the outer wall of the limiting plate 6 and the inner wall of the device body 2, and a magnetic door 8 is hinged on the front of the device body 2, and a transparent window is provided on the magnetic door 8, through which the heating status of the semi-cured sheet can be easily observed.

[0033] Specifically, the elastic member 7 can be selected as a spring according to actual conditions, so as to facilitate the moving rod 5 to move back to the initial position when no external force is applied.

[0034] Specifically, the glass fiber cloth impregnated with resin glue is placed on the tray 4, and multiple trays 4 are pushed and inserted between two opposite C-shaped blocks 3. Then the magnetic door 8 is closed, and the wall of the magnetic door 8 is against the tray 4. The tray 4 is pushed further into the device body 2. The moving rod 5 is pushed backward by the thrust of the tray 4 and compresses the elastic part 7. As the magnetic door 8 is completely closed, the glass fiber cloth is heated in the heating chamber of the device body 2. After the heating is completed, the magnetic door 8 is opened to move it away from the tray 4. Under the elastic action of the elastic part 7, the moving rod 5 extends outward and moves back to the initial position, pushing the tray 4 out a certain distance. There is no need to put your hands into the device body 2, which makes it easy to take out the tray 4 to cool the glass fiber cloth into a semi-cured sheet.

[0041] The fan 18 and the electric heating wire 20 cooperate with each other to blow hot air into the ventilation pipe 19. The hot air passes through the ventilation pipe 19 and then through the through hole into the heating chamber of the device body 2 to heat the material; through the ventilation slots 21 on the wall of the tray 4, the air in the device body 2 can flow up and down during heating, so that each tray 4 is heated evenly.

[0042] like Figure 6 As shown, a baffle 22 is provided between the ventilation pipe 19 and the movable seat 1, an electric push rod 23 is provided on one side of the ventilation pipe 19, and the telescopic end of the electric push rod 23 is connected to the outer wall of the baffle 22; the baffle 22 is located at the top opening of the movable seat 1, and a filter is fixedly installed on one side of the movable seat 1 to prevent external dust from entering the heating chamber of the device body 2 during heating.

[0043] Specifically, a controller can be installed in combination with a circuit to control the operation of the fan 18, the electric heating wire 20 and the electric push rod 23, and the specific circuit is selected according to actual conditions; the movement of the baffle 22 is controlled by the electric push rod 23 to change the shielding area of the baffle 22 for the top opening of the movable seat 1, thereby controlling the air volume in the ventilation pipe 19 and realizing the control of the temperature in the heating chamber of the device body 2.
