the operation of rotating the turntable 301 back and forth by 180 degrees is repeated, and at this time, the four films are all arranged in a staggered manner, so that the staggered edge stacking of the four edges of each film and the previous film is realized, and the staggered effect schematic diagram of the staggered edge stacking of the films by using the steps is shown in fig. 8.
In the function of the mechanical misalignment stacking device designed in the example, the device obtains the metalized films released along the parallel direction, the color mark identification points on the films are identified and positioned through the color mark sensors, the films are made to be located at corresponding positions, the rectangular patterns of the cut metalized films are kept, and the obtained laminated films are adsorbed and positioned. Thus, after the cutting to obtain the precise position parameters of the metallized film in the mechanical device, the adsorption disc moves along the vertical direction to reach the position for stacking the film, and the position corresponds to the position parameters for placing the film. The function of edge staggering in the mechanical film stacking is completed by the diagonal offset of 180 degrees of rotation each time through an eccentric turntable at the position of stacking the films in a mechanical device. The requirement for placing the capacitor lamination is met through repeated, efficient and accurate mechanical movement.
Because of the diaphragm of the three-dimensional array capacitor, the laminated film needs to be staggered and stacked on 4 sides, and two rectangular films with positive and negative polarities are staggered and walk in the diagonal direction
Unit lengthAnd staggering the working modes of one unit.
Therefore, the mechanical type staggered edge stacking device of the embodiment applies a precise mechanical design and keeps position parameters in a mechanical structure; the problem of repeated placement is solved by applying the precision of mechanical motion; in the implementation process, the color code positioning points in the automation technology are matched and applied, and the on-line scanning positioning technology is adopted, so that the identification and alignment of the film by machinery are realized.
The staggered edge stacking device has the advantages of low manufacturing cost and high working efficiency, meets the requirement of repeated film stacking, and can finish the preparation of the stacked capacitor.
