Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of automobile interior parts production, in particular to a vacuum activation auxiliary tooling. Background Art
[0002] The automobile industry in China has developed rapidly, and the new energy vehicles are being updated at an increasingly fast pace. There are not only high requirements for the performance of automobiles, but also higher requirements for the comfort of automobile interiors. The involved part processes are more complex, and there are also higher requirements and challenges for the feasibility of production and manufacturing.
[0003] The production process of the hot melt adhesive instrument panel 3D mesh and skin covering process with stitches in an automobile is generally as follows: 3D mesh and skin roller gluing → 3D mesh and skin punching → 3D mesh manual fitting → 3D mesh vacuum activation (the activation temperature of the hot melt adhesive is high, and only the mold pressing tool is used to heat and activate the glue, resulting in a too long production beat. Therefore, the 3D mesh activation process is added to reduce the mold pressing beat and improve the production efficiency) → skin sewing (functional line + decorative line) → skin pre-pasting for alignment (using an alignment tooling, which is convenient for manual operation and has good stitch quality) → hot pressing + cold pressing integrated edge wrapping (the glue is activated and the equipment automatically reversely wraps and closes the corners, reducing manual labor) → trimming the redundant skin + manual reverse wrapping of the corners that cannot be collected by the equipment → finished product.
[0004] Most of the covering parts in the existing technology market are still mainly covered with water-based glue. Although the covering process of hot melt adhesive has been relatively mature, the market penetration rate is low. There are great differences in the activation temperature and performance of the two kinds of glue. For example, the activation temperature of the hot melt adhesive is high, and the viscosity is large after being completely activated. Therefore, higher requirements are imposed on the techniques of the covering personnel compared with water-based glue. During covering, problems such as poor covering of the skin edge due to poor covering of the 3D mesh covering edge are likely to occur, and it is more difficult to repair the defects after covering. For the already covered products, it is unacceptable to users that the covered 3D mesh and skin are defective due to the activation process. Therefore, it is very necessary to develop tooling to improve the qualified rate of the activated products. Summary of the Utility Model
[0005] Aiming at the problems of the deficiencies in the existing technology, the utility model provides a vacuum activation auxiliary tooling to solve them.
[0006] The technical solution adopted by the utility model is as follows:
[0007] A vacuum activation auxiliary tooling, comprising a bottom plate, a base, a bearing, a shielding plate, a turning plate, a connecting block, a magnet and a tooling fixture. The bottom plate is installed on a vacuum activation device, the tooling fixture is fixed on the bottom plate, the bearing is fixed on the bottom plate through the base, one side of the turning plate is fixedly connected to the shielding plate by screws, and the other side is fixedly connected to a shaft core, which is inserted into the bearing shaft hole. The magnet is fixed on the tooling fixture, and a magnet is also fixed on the turning plate corresponding to the position of the magnet, which can be attracted to the magnet.
[0008] The shielding plate is lengthened by being fixedly connected through a connecting block.
[0009] The vacuum activation auxiliary tooling of the present utility model is scientifically and reasonably designed, simple and practical in structure, convenient to use, safe and reliable in function, and low in manufacturing cost. It solves the problem that in the coating of automotive instrument panel covering parts on a vacuum activation device, poor coating at the edge of the skin is likely to occur due to poor 3D mesh coating edges, and ensures the improvement of the first-pass rate of products.

[0015] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described below are only used to explain the present utility model. In these descriptions, the key words that need to be noted include "tooling fixture", "shielding plate", "turning plate", "magnet" and "insertion connection", etc. These are only for the convenience of describing the present utility model and simplifying the description, and therefore cannot be understood as limitations to the present utility model.
[0016] As Figure 1 and Figure 2As shown, the vacuum activation auxiliary tooling of the present invention is used to solve the problem of poor skin edge covering caused by poor 3D mesh (labeled as M in the accompanying drawings) covering during covering of automobile dashboards on vacuum activation equipment. The poor 3D mesh covering edge is solved by the present invention. The present invention includes a base plate 1, a base 2, a bearing 3, a baffle 4, a flip plate 5, a connecting block 6, a magnet 7 and a jig T. The base plate 1 is installed on the vacuum activation equipment, the jig T is fixed on the base plate 1, and the bearing 3 is fixed on the base plate 1 through the base 2. One side of the flip plate 5 is fixedly connected to the baffle 4 by screws, and the other side is fixedly connected to the shaft core. The shaft core is inlaid with the shaft hole of the bearing 3, forming a structure in which the flip plate 5 and the base plate 1 are hinged. The flip plate 5 and the baffle 4 can be flipped by relying on the bearing 3. Figure 2 As shown, the magnet flip plate 5 is fixed to the mold T. A magnet is also fixed to the flip plate 5 at the position corresponding to the magnet 7, which can be attracted to the magnet 7. For larger automobile instrument panel components, the two shields 4 are fixedly connected by a connecting block 6 to extend them, or further supported by adding a base 2, bearings 3, and flip plate 5 to ensure that they can cover all edges of the covered 3D mesh during use.
[0017] See also Figure 3 As shown, when using the present invention, the vacuum activation equipment is used to initially apply the 3D mesh to the automotive instrument panel product C (frame), which is then placed in a mold T. Next, the flip plate 5 of the vacuum activation auxiliary tooling is flipped over, and the shielding plate 4 is pressed and covered over the edge of the 3D mesh. The flip plate 5 is then secured by magnets 7. Because the shielding plate 4 covers and covers the edge of the 3D mesh, the vacuum activation equipment then heats and activates the 3D mesh glue, resulting in a smooth, flat 3D mesh-covered edge.
[0018] The above is only one embodiment of the present invention. Those skilled in the art will readily appreciate that the present invention may have various modifications and variations, which are not exhaustively described here. However, any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of protection claimed by the present invention.
