Description

Technical Field

[0001] The utility model relates to the technical field of copper clad laminate production, in particular to an anti-static weighable prepreg lamination device for copper clad laminates. Background Art

[0002] Copper Clad Laminate (CCL for short) is a product made of wood pulp paper or glass fiber cloth as reinforcing materials, impregnated with resin, covered with copper foil on one or both sides, and hot pressed. Copper Clad Laminate is a basic material in the electronics industry, mainly used for processing and manufacturing printed circuits (PCB), and widely used in electronic products such as televisions, radios, computers, computers, and mobile communications. However, prepreg is one of the main raw materials in the production of copper clad laminates, which mainly plays an insulating role. The prepreg is made of treated glass fiber cloth, impregnated with resin glue, and then heat treated (pre-baked) to make the resin enter a semi-cured state. Copper Clad Laminate is made by laminating the above-mentioned prepreg with copper foil on one or both sides under high temperature and high pressure conditions.

[0003] However, there are diversified requirements for the thickness of existing copper clad laminates. Copper clad laminates will use different numbers or types of prepregs according to the needs. When copper clad laminates need to use different types of prepregs, the loading of prepregs becomes inconvenient, which affects the production efficiency of the device. In addition, when the prepregs are being loaded, there is no good anti-static and weighing. The prepregs are not only easily affected by static electricity, but also have certain requirements for their weight when loading and stacking. It is time-consuming and laborious to measure them one by one manually. Secondly, after the copper clad laminate is hot-pressed and stacked with the prepreg, the copper clad laminate is relatively hot and inconvenient to take out. Therefore, we propose an anti-static and weighable prepreg stacking device for copper clad laminates. Utility Model Content

The support frame on the loading device is pushed to slide on the slide slot by the No. 1 electric telescopic rod, so that the suction cup moves to the top of the No. 2 anti-static tray and aligns with the semi-cured sheet or copper clad laminate to be adsorbed. At this time, the air pump is started, and the air pump generates suction in the plurality of suction cups at the lower end of the connecting plate through the connecting pipe, and as the No. 2 electric telescopic rod drives the connecting plate to adjust its height, the semi-cured sheet or copper clad laminate is sucked up, so that the device can load semi-cured sheets of different quantities or different types as needed.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] 1. When the copper clad laminate and the prepreg are to be hot-pressed, the required prepreg is first placed in the No. 2 anti-static tray on the storage device. The anti-static tray adds special polymer chains to the raw materials to make the finished product have permanent static dissipation performance. The finished product has good mechanical strength and heat resistance, good impact resistance, strong chemical corrosion resistance, and will not change its anti-static performance due to the environment, time and temperature. In addition, the two partitions set in the No. 2 anti-static tray can divide it into multiple storage spaces, so that the device can store copper clad laminates or different types of prepregs. The prepreg is stored, and then the support frame on the loading device is pushed to slide on the slide groove through the No. 1 electric telescopic rod, so that the suction cup moves to the top of the No. 2 anti-static tray and aligns with the semi-cured sheet or copper clad laminate to be adsorbed. At this time, the air pump is started, and the air pump generates suction in several suction cups at the lower end of the connecting plate through the connecting pipe, and the No. 2 electric telescopic rod drives the connecting plate to adjust its height, thereby sucking up the semi-cured sheet or copper clad laminate, so that the device can load different quantities or different types of semi-cured sheets according to needs, thereby improving the practicability of the device.

[0017] 2. After the prepreg is sucked up and the support frame moves to the top of the weighing device, the air pump stops generating suction, and the prepreg is placed in the No. 1 anti-static tray on the weighing device. At this time, the prepreg is weighed by the weight sensor to prevent the prepreg from not meeting the specifications. After weighing, the prepreg that meets the specifications is sucked up again and placed in the hot pressing seat on the ejection device as the support frame slides. The loading steps are repeated. After the prepreg and the copper clad laminate are all placed as needed, the hot pressing plate is heated by the electromagnetic heater on the hot pressing device. At this time, the No. 3 electric telescopic rod pushes the hot pressing plate downward into the hot pressing groove, thereby completing the hot pressing and lamination of the copper clad laminate.

[0018] 3. After the copper clad laminate is laminated by hot pressing, two fans on the heat dissipation device blow air toward the vents through the air outlets thereon, thereby accelerating the heat dissipation efficiency of the mounting frame. After the air is blown, the hot pressing seat and the copper clad laminate thereon are ejected by the hydraulic cylinder, thereby facilitating the unloading of the copper clad laminate.
