[0015] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.
[0016] In some embodiments, according to the bottom guard plate preparation device of the embodiment of the present utility model, the bottom guard plate preparation device includes an infiltration box 1, a molding mechanism and a control mechanism. The infiltration box 1 is connected to a first vacuum pump 2 and a pressure relief valve. The infiltration box 1 is used to infiltrate the material, the first vacuum pump 2 is used to form a vacuum environment in the infiltration box 1, and the pressure relief valve is used to send outside air into the infiltration box 1. The molding mechanism includes a mold, a transfer part, a heating part and a second vacuum pump. The transfer part places the infiltrated material into the mold, the second vacuum pump is used to vacuum the mold, the heating part is connected to the mold to heat the mold, and the control mechanism includes a vacuum gauge 4 and a temperature sensor. The vacuum gauge 4 is connected to the vacuum part to detect the vacuum degree of the mold, and the temperature sensor is used to detect the temperature of the mold. The infiltration box 1 improves the infiltration effect by vacuum infiltration. The resin can penetrate into the micropores of the material more quickly, thereby improving the impregnation efficiency and reducing the occurrence of defects such as bubbles and pores. The mold of the molding mechanism completes the molding of the material through vacuuming and heating. The transfer part is used to transfer the infiltrated material into the mold to improve production efficiency. The control mechanism detects the state of the mold through the vacuum gauge 4 and the temperature sensor to facilitate adjustment to meet the production needs of different materials. The vacuum gauge 4 can be a mechanical vacuum gauge 4. The vacuum environment helps the resin to penetrate the material more evenly and improve product quality. By removing air, a bubble-free environment is provided for the resin, thereby reducing pores and defects. The combination of the heating element and the vacuum pump ensures uniform heating and compaction of the material during the curing process, reducing internal defects. The heating of the mold helps to speed up the curing speed and improve production efficiency.
[0017] The bottom guard plate preparation device according to the embodiment of the utility model has the advantages of high impregnation efficiency and high product quality.
[0018] In some embodiments, the bottom guard plate preparation device also includes a pre-processing mechanism, which includes a pre-pressing box and a pre-heating component. The pre-pressing box is used to compact the material, and the pre-heating component is used to heat the material in the pre-pressing box.
[0019] Specifically, the pre-processing mechanism is used to pre-process the material to improve the material quality, reduce the gas inside the material and increase the material temperature. The compacted material produces fewer bubbles and defects during the infiltration process, and preheating can increase the subsequent processing speed.
[0020] In some embodiments, the bottom guard plate preparation device further includes a conveying member, which is used to convey the material in the pre-pressing box to the infiltration box 1.
[0021] Specifically, the conveying member can be a conveyor belt or a robotic arm. The robotic arm clamps the pre-processed materials to improve production efficiency, reduce manual participation, shorten material processing time, and reduce operational errors.
[0022] In some embodiments, the preheating element is an infrared heater or a microwave heater.
[0023] Specifically, infrared heaters heat materials through infrared radiation, quickly and evenly raising their temperature. Microwave heaters use microwave energy to directly heat the interior of the material, improving heating efficiency and uniformity. Both heaters heat without direct contact with the material, allowing for greater flexibility in their installation location.
[0024] In some embodiments, multiple pairs of rollers are provided in the pre-pressing box, and the rollers are used to compact the material.
[0025] Specifically, pressurization can reduce air voids in the material and improve the density and uniformity of the material.
[0026] In some embodiments, the infiltration box 1 includes a working chamber 11 and a liquid storage chamber 12. The liquid storage chamber 12 is connected to the top of the working chamber 11 through a first pipeline. The working chamber 11 is connected to the liquid storage chamber 12 through a second pipeline. The vacuum pump is connected to the working chamber 11 through a pipeline for vacuuming, and the pressure relief valve is connected to the working chamber 11.
[0027] Specifically, the infiltration tank 1, by providing a working chamber 11 and a liquid storage chamber 12, separates the resin storage area from the material infiltration area, reducing resin contamination and protecting resin quality. Vacuum infiltration of the material is performed within the working chamber 11. A vacuum pump creates a negative pressure environment within the working chamber 11, and a pressure relief valve regulates the pressure within the working chamber 11 to allow for the introduction of ambient air after infiltration. Two pipelines, forming a loop between the working chamber 11 and the liquid storage chamber 12, recycle the resin within the working chamber 11, reducing waste.
[0028] In some embodiments, the control mechanism further includes a control panel 3 , which is electrically connected to the vacuum gauge 4 , the temperature sensor, and the vacuum pump.
[0029] Specifically, the control panel 3 may be provided with a display screen to display parameters such as pressure and temperature for the convenience of adjustment and control by the staff. The control panel 3 helps the staff to monitor and adjust the vacuum degree and temperature in real time, thereby ensuring the stability and repeatability of the process.
[0030] In some embodiments, the bottom guard plate preparation device also includes an anti-static mechanism, which includes an electrostatic eliminator and a grounding chain. The electrostatic eliminator is located next to the infiltration box 1 to eliminate static electricity of the material. One end of the grounding chain is connected to the outer surface of the infiltration box 1, and the other end of the grounding chain is connected to the ground.
[0031] Specifically, the anti-static mechanism can prevent static electricity from damaging materials or finished products. The static eliminator blows ionized air onto the surface of the material to neutralize static electricity. The grounding chain connecting the equipment and the ground can eliminate static electricity accumulation and improve product quality.
