Description

Composite high-temperature cloth for transmission of laminating machine and laminating machine

Technical Field

The utility model relates to a laminator equipment technical field, in particular to laminator of novel high temperature cloth and this high temperature cloth of use of laminator transmission usefulness.

Background

With the rapid development of photovoltaic modules, the demand for high-power solar panels increases, and with the increase in power of solar panels, the size of the solar photovoltaic modules constituting the solar panels also increases, with the currently common specification being 2.5m in length by 1.5m in width. In order to adapt to the change of the size of the photovoltaic module, the size of the laminating machine is larger and larger, the number of the single conveying assemblies of each laminating machine is generally 7-8, the weight of each conveying assembly of the laminating machine is up to 500kg, the task of conveying the photovoltaic module is completed by high-temperature cloth, and the requirements on the strength and the wear resistance of the high-temperature cloth serving as a conveying part are higher and higher. The heavier the weight of the photovoltaic module transmitted, the thicker the thickness of the high-temperature cloth adopted, and in the conventional application at present, the thickness of the high-temperature cloth is 0.35mm, and the high-temperature cloth with the specifications of 0.4mm, 0.5mm and 0.7mm is also provided according to the different requirements of the transmission weight and the wear resistance. The high-temperature cloth is arranged on the pull rod and needs to penetrate through the whole working cavity of the laminating machine, and the upper cover of the laminating machine is pressed on the high-temperature cloth when the upper box and the lower box are closed. As is well known, when a working cavity of a laminating machine works, the working cavity of the laminating machine needs to be vacuumized, the vacuum pressure reaches 10-20Pa, sealing rubber strips are arranged on the periphery of an upper cover of the working cavity, the rubber strips arranged along the running direction, namely long-edge sealing rubber strips, are in direct contact with a lower cavity iron plate for sealing, and the rubber strips arranged at two ends of the upper cover and perpendicular to the running direction, namely short-edge sealing rubber strips, are pressed on high-temperature cloth. In order to prevent the adhesive solution from adhering to the silica gel plate during lamination, the laminator generally also is provided with upper circulation high temperature cloth for isolating the photovoltaic module from the silica gel plate to protect the silica gel plate, the thickness of the upper high temperature cloth is 0.25mm, 0.35mm and 0.5mm generally, when the upper box and the lower box are closed, the sealing rubber strips of the two short edges are pressed on the two layers of high temperature cloth, the sealing structure at the sealing rubber strips of the two short edges is sealing rubber strips, the upper high temperature cloth, the lower high temperature cloth and the lower box plate, the thicker the high temperature cloth is, the rougher the high temperature cloth is, the more the number of layers between the sealing rubber strips and the lower box plate is, the poorer the sealing effect between the sealing rubber strips of the short edges and the lower box plate is, and the poorer the sealing effect of the working cavity is caused. In order to improve the sealing performance of the working cavity, the thickness of the high-temperature cloth needs to be reduced as much as possible, the smoothness of the high-temperature cloth needs to be increased, and the number of layers needs to be reduced. In order to improve the sealing performance of the working cavity and simultaneously avoid the problem of vacuum adsorption between the lower high-temperature cloth and the table top, in the prior art, the lower surface of the high-temperature cloth generally used for transmission adopts a rough surface, the upper surface of the high-temperature cloth adopts a smooth surface, and the thickness of the high-temperature cloth is increased. The rough surface of high temperature cloth and minor face joint strip correspond the department and should set the smooth surface to in order to improve the leakproofness between minor face joint strip and the lower boxboard down, and the rough surface can release vacuum state after the lamination is accomplished rapidly. The scheme of arranging the smooth surface is divided into two schemes, namely, gluing the position of the rough surface of the high-temperature cloth, which is used for sealing with the adhesive tape, to form the smooth surface, and sticking a thin high-temperature adhesive tape to the position to form the smooth surface. By adopting the two schemes, time and labor are wasted during gluing, the glue needs to be coated for many times, the glue needs to be uniform, the durable time is short when the high-temperature adhesive tape is pasted, the high-temperature adhesive tape needs to be replaced periodically, the labor intensity of workers is increased, and the working efficiency is reduced. In addition, in order to obtain a smooth surface on the upper surface of the high-temperature cloth, the upper surface of the lower high-temperature cloth needs to be coated, the thicker the coating is, the higher the cost is, and the thickness of the common coating is 0.25mm, so that the thickness of the high-temperature cloth is increased overall, the overall thickness of the high-temperature cloth between the sealing rubber strip and the lower box plate reaches at least 0.8mm, the sealing effect is poor, the smooth sealing surface is arranged on the rough surface, the operation process is increased, and the working efficiency is reduced.
