Embodiment:
Below in conjunction with accompanying drawing, the present invention is elaborated, heat-curable glue of the present invention is pasted solidification equipment, as shown in Figure 1, comprises pedestal 1 and is arranged on pedestal 1 interior ultrasonic vibration installation and Liqiud-gas mixing device.Wherein the structure of ultrasonic vibration installation as shown in Figure 3, is made of elastic plate 3 and piezoelectric ceramic piece 9.The Liqiud-gas mixing device structure is made of shell 6, inlet pipe 7, escape pipe 8, gas-liquid mixture 11 as shown in Figure 5, and its housing 6 can be selected elastomeric material.Ultrasonic vibration installation is fixed on the upper end of pedestal 1, the groove that is processed to form with the upper surface of pedestal 1 consists of ultrasonic vibration groove 2, Liqiud-gas mixing device is arranged in ultrasonic vibration groove 2, lower end at pedestal 1 is processed to form groove, the upper surface of groove is the lower surface of elastic plate 3, and piezoelectric ceramic piece 9 sticks on the lower surface of elastic plate 3.Also can place one deck matrix supporting pad 4 on elastic plate, matrix supporting pad 4 preferred rubber pads are processed to form some matrix standing grooves 5 at the upper surface of rubber pad.Liqiud-gas mixing device the input steam after, the temperature of whole device, gross weight reach invariable after, be positioned on the viscose glue matrix that is placed in the rubber pad surface groove.
The present invention utilizes the elastic plate in the inverse piezoelectric effect excitation ultrasound vibrating device of piezoelectric ceramics to carry out reciprocal micro breadth oscillation, form a plane of oscillation at the elastic plate upper surface, and by rubber pad, the micro breadth oscillation of the plane of oscillation is passed to viscose glue matrix in the groove that is placed on rubber pad, the glue-line between mutual viscose glue matrix is evenly distributed at sticking veneer; Next utilizes the mode of Liqiud-gas mixing device input steam to apply constant pressure for the viscose glue matrix, heat-curable glue required continuous in the matrix taping process is provided, make simultaneously the bondline thickness compression between mutual viscose glue matrix and evenly distribute, gas-liquid mixed rubber device inner chamber is full of the gas-liquid mixture of steam, liquid in addition, in this moment, cavity temperature is the boiling point of liquid, for the curing of heat-curable glue provides constant temp; At last, increase the scantlings of the structure ratio of solidification equipment, at the some grooves of the surface working of rubber pad, can realize the mass production of matrix viscose glue.Therefore, the heat-curable glue solidification equipment of proposition of the present invention has following characteristics:
(1) solidify for the heat-curable glue of matrix adhered layer constant temperature is provided, the height of temperature becomes liquid after by steam cooling, then is determined by the boiling point of liquid gasification, changes by add the impurity temperature-adjustable in steam or liquid;
