Through the mode, the rubber sheet stretching device disclosed by the invention shares a set of production equipment and a set of stretching die, can ensure that the relative position of the rubber sheet on the shielding cover is accurate, improves the production efficiency and reduces the production cost.
Description
Technical Field
The invention relates to the technical field of film lamination, in particular to a film and shield cover forming and rubberizing process.
Background
The original production process for attaching the film to the shielding case comprises the following steps: the film is produced by a set of mould, and a section of rubber disc is packed; the shielding cover is produced by another set of mould, and the other type of rubber disc is packed; meanwhile, at the delivery client, the shielding case is placed at the client, then the film is pasted manually, the unfolding shape of the shielding case is larger than the appearance of the film, the film and the shielding case are manually pasted outside the mold, as shown in fig. 1, due to artificial factors, when a product is pasted, the product is inaccurate in position and easily infected with quality risks such as dust and the like due to deviation of the placement position, so that the labor cost is increased, the production efficiency is reduced, the quality risks such as poor product pasting and the like are increased, and on the basis of the defects and the shortcomings, the existing technology is necessarily improved, and the film and shielding case forming pasting technology is designed.
Disclosure of Invention
The invention mainly solves the technical problem of providing a rubber sheet and shield cover molding rubberizing process, which shares a set of production equipment and a set of stretching die, can ensure that the relative position of the rubber sheet on the shield cover is accurate, improve the production efficiency and reduce the production cost.
In order to solve the technical problems, the invention adopts a technical scheme that: the forming and rubberizing process of the film and the shielding case comprises the following steps:
s1, the discharge ends of the shielding cover and the film strip are respectively determined to be in relative positions through corresponding positioning blocks, and the width of the film strip is smaller than that of the shielding cover strip;
s2, pointing the adhesive layer of the film material strip, and pressing the film material strip on the shielding case material strip through the shielding case material strip and an automatic pressing device;
s3, the laminating material in the step S2 enters an automatic cutting device, and the cutting knife cuts one side of the film material belt without the adhesive layer to separate the film into the required film shape;
s4, punching the shielding cover material belt attached with the film into a required unfolding shape by a blanking punch customized in a punching machine and a stretching die;
and S5, the punched shielding cover material belt passes through a drawing die, a positioning punch in the drawing die guides the punched unfolded material sheet to drawing stations with different parameters correctly to finish the continuous drawing action to achieve the effect of a finished product, and the finished product after drawing is filled into a packaging bag through scattered parts of a blanking station in the die.
Preferably, the automatic pressing device can adopt opposite extrusion rollers to press and discharge materials.
Preferably, the shape of the cutting knife is customized to be consistent with the shape of the film, and the height of the cutting knife is adjusted to ensure that the cutting knife does not touch the raw material of the shielding cover.
Compared with the prior art, the invention has the beneficial effects that:
one set of production equipment and a stretching die are shared, so that the relative position of the film on the shielding cover can be ensured to be accurate, the production efficiency is improved, and the production cost is reduced.
