Description

Technical Field

[0001] The utility model relates to the technical field of automobile accessories, in particular to a vacuum adsorption platform that saves the amount of hot melt adhesive. Background Art

[0002] With the development of the automobile industry, people have higher and higher requirements for the comfort, functionality and environmental quality of the interior space of the car. In order to meet better usage requirements, more and more car companies have adopted hot melt adhesive as the adhesive for bonding car interiors. Specifically, the existing car interiors mainly refer to car roofs, dashboards, ABC columns, interior door panels, seats, and trunk lids. In the process of automobile manufacturing, car companies use hot melt adhesive to compound surface materials onto the skeleton, thereby improving the comfort of car driving. As a key process in the entire process, the platform hot melt adhesive roller is the main equipment for evenly coating hot melt adhesive on the surface material to be bonded.

[0003] In the current process, workers place pre-cut fabrics on a mobile platform and fix them by means of chucks, hooks or double-sided tape. After starting the gluing process, the mobile platform feeds the fabric into the glue rolling unit, and the hot melt adhesive is transferred to the fabric through the contact between the fabric and the glue roller. In this process, since the surface of the glue roller is fully covered with hot melt adhesive, the surface of the fabric after gluing is also covered with hot melt adhesive, which makes it impossible to apply only the designated area according to the customer's needs. In addition, for the subsequent cutting and compounding processes, the areas that do not contact the skeleton or do not need adhesive will also waste hot melt adhesive. In the subsequent sewing process, due to the long-term work of the sewing steel needle during sewing, the temperature of the steel needle will reach about 70-80°C. This temperature will soften the glue and bring it to the other side of the epidermis along with the sewing thread, so that if there is hot melt adhesive in the seam area, there will be a problem of glue penetration, resulting in defective products. Therefore, the existing process has limitations. Utility Model Content
