Description

Technical Field

[0001] The utility model relates to the technical field of carbon fiber material processing, in particular to a carbon fiber material bonding fixture. Background Art

[0002] Carbon fiber material refers to high-strength and high-modulus fibers with a carbon content of more than 90%. It is made of acrylic and viscose fibers as raw materials and is made through high-temperature oxidation and carbonization. It has the best high-temperature resistance among all chemical fibers and is an excellent material for manufacturing high-tech equipment such as aerospace. Carbon fiber boards are made of high-quality carbon fiber raw materials and good basic resins. They have good properties such as high tensile strength, corrosion resistance, shock resistance, and impact resistance. Bonding fixtures are used when processing carbon fiber boards to facilitate the combination of multiple carbon fiber boards according to product needs.

[0003] When using the existing carbon fiber material bonding fixture, one of the carbon fiber plates is generally positioned and fixed by the fixture first, and then adhesive is applied to the rough surface on its top, and then the other carbon fiber plate is driven closer to the side of the carbon fiber plate on the fixture, and the bonding operation of the two carbon fiber plates is achieved by squeezing the transmission component. In this process, since there is no pre-pressing component on the outside of the carbon fiber plate, it is impossible to limit it in advance from the outside of the carbon fiber plate before the bonding operation. This causes occasional offset during the assembly of the carbon fiber plates. In mild cases, the staff needs to scrape off the glue and re-bond it. In severe cases, the carbon fiber plates will be scrapped, resulting in a waste of resources, which is not conducive to the bonding work of the carbon fiber plates. Utility Model Content
