Automatic automobile trim coating device with sewing thread

Abstract

The invention provides an automatic automobile trim coating device with a sewing thread. The coating device comprises a lower mold and an upper mold. The upper mold is provided with a lifting mechanism, and side pushing mechanisms for clamping workpieces on the lower mold are arranged on both sides of the lower mold. The lower mold comprises a lower mold body, lateral lower molds, a lower mold mounting plate, sewing thread middle jacking molds, a main spring component and an auxiliary spring component. Two symmetrical sewing thread middle jacking mold mounting grooves are formed in edge positions, close to both sides, of the lower mold body. The sewing thread middle jacking molds are mounted in the sewing thread middle jacking mold mounting grooves. The automatic automobile trim coating device has the advantages that the sewing thread middle jacking molds with positioning and suction functions and the side pushing mechanisms are added to the lower mold, automatic coating of trim products can be realized; front and back edges of a cover are sucked by vacuum suckers to guarantee the shape stability of the sewing thread during coating, the position degree and flatness of the sewing thread after coating are also ensured, and accordingly, the products meet quality standards.

Description

technical field [0001] The invention relates to the technical field of automobile interior trim covering, in particular to an automatic covering device for automobile interior trim with a sewing thread. Background technique [0002] In the coating and bonding process of various leather materials for automotive interior parts, manual coating and bonding and existing automatic hemming equipment are the most commonly used, because the corresponding automotive interior parts often have complex structures and uneven profiles. In the case of rules and other conditions, the efficiency of manual covering is low and the covering effect is not good. The sewing thread of existing automotive interior products is usually the shape of a single top thread after sewing with double skins, and the hemming mechanism currently on the market usually has double skins. After sewing, the shape and positioning of the single top thread is difficult and the position accuracy is unstable. The quality d...

[0002] In the coating and bonding process of various leather materials for automotive interior parts, manual coating and bonding and existing automatic hemming equipment are the most commonly used, because the corresponding automotive interior parts often have complex structures and uneven profiles. In the case of rules and other conditions, the efficiency of manual covering is low and the covering effect is not good. The sewing thread of existing automotive interior products is usually the shape of a single top thread after sewing with double skins, and the hemming mechanism currently on the market usually has double skins. After sewing, the shape and positioning of the single top thread is difficult and the position accuracy is unstable. The quality defect problem, the patent number 201320744155.2, discloses a utility model patent named "A Line Alignment Tool for Automotive Interior Parts Products". This patent solution can be compared It is good to ensure the position accuracy of the sewing thread, but it needs to be pre-coated by hand. After pressing the sewing thread with a thread setting knife, it can be covered manually. The disadvantage is that manual participation cannot be avoided, and it has a negative effect on the proficiency of personnel. High requirements, complex operation

Patent No. 201320772843.4 also discloses a utility model patent titled "Positioning device for soft-coated skin sewing thread of automobile door panel interior". Positioning, but it cannot solve the problem of serial movement of the skin due to stress (mistouch) during the coating process
