Example 1

Referring to fig. 1, the membrane guide mechanism for high-speed wide-width lamination of the present embodiment is shown. Specifically, the diaphragm guide mechanism includes a first linear drive assembly 1, a second linear drive assembly 2, and a guide roller assembly 3.

Wherein the guide roller assembly 3 is arranged above the lamination table 5. And specifically, the guide roller assembly 3 comprises at least one pair of guide rollers 31, the pair of guide rollers 31 are arranged in parallel, and the gap between the two rollers is the position of the diaphragm roller. During lamination, the membranes are guided through the rollers from the roller gaps of the guide rollers 31 arranged in pairs and are stacked on the lamination table 5.

More specifically, the guide roller 31 is a strip-shaped roller longer than a conventional roller and is designed to accommodate the lamination of the wide and large cells, so as to guide the separator of the wide and large cells. In addition, the planes of any pair of guide rollers 31 are parallel to the table surface of the lamination table 5, so that the guide function of the diaphragm along the width direction in the lamination process through the rollers is kept balanced, and the phenomenon of uneven stress or inclination of the guide is avoided.

Since the length of the guide roller 31 is longer than that of a common roller, that is, the length-diameter ratio is larger, and the wide diaphragm is more easily deformed or shaken in the process of guiding the wide diaphragm, by providing two or more pairs of guide rollers 31, the guide rollers 31 can be more stable in guiding the wide diaphragm through the rollers, and the guidance of the wide diaphragm is better. Furthermore, the roller gaps of the at least one pair of guide rollers 31 are located in the same vertical plane. In this embodiment, the guide roller assembly 3 comprises two pairs of guide rollers 31. And in a specific implementation, the number of pairs of guide rollers 31 can be adapted according to the width amplitude variation of the actual diaphragm.

The first linear drive assembly 1 and the second linear drive assembly 2 serve as driving power for driving the guide roller assembly 3 for high-speed linear reciprocating movement of the laminations. Furthermore, optionally, in order to achieve a good linear driving effect, the first linear driving assembly 1 and the second linear driving assembly 2 are linear modules, and the linear directions of the linear modules are perpendicular to the axial direction of the guide roller 31. The first linear driving assembly 1 and the second linear driving assembly 2 are symmetrically arranged at two ends of the guide roller assembly 3 and are respectively in transmission connection with two ends of the guide roller assembly 3, in particular to the guide roller 31 in the guide roller assembly 3. The first linear driving assembly 1 and the second linear driving assembly 2 are controlled by servo linkage, have good responsiveness, and can synchronously drive the guide roller 31 in the guide roller assembly 3 to reciprocate along the axial direction of the vertical roller without delay so as to guide the lamination of the diaphragm.

In a specific arrangement, the guide roller assembly 3 is connected with the first linear driving assembly 1 and the second linear driving assembly 2 through the roller mounting support plate 4, so that the first linear driving assembly 1 and the second linear driving assembly 2 can be in effective transmission connection with the guide roller assembly 3, and the guide roller assembly 3 and the lamination table 5 are kept at a corresponding space distance to meet the space requirement of lamination. One end of the roller mounting plate 4 is fixed on the linear driving component and can be driven by the linear driving component to move linearly; and the end part of the guide roller 31 in the guide roller assembly 3 is fixedly connected and arranged on the other end of the roller mounting plate 4, so that the guide roller 31 can synchronously and linearly move along with the roller mounting plate 4 under the drive of the linear drive assembly, and the guide roller 31 is suspended above the lamination table 5.

In the embodiment, in order to facilitate the arrangement of the lamination table 5 and the components for laminating the press plates and the like, and simultaneously save the occupied space of the mechanism arrangement, the first linear driving component 1 is arranged above the guide roller assembly 3, the second linear driving component 2 is arranged below the guide roller assembly 3, and the first linear driving component 1 and the second linear driving component 2 are arranged in a central symmetry manner. So, make the setting that is used for components such as lamination clamp plate of enough space reservation of the one side of being close to first linear drive assembly 1 of lamination platform 5, can make simultaneously that first linear drive assembly 1 is installed unreeling and fixed the structure of passing the roller at the diaphragm, save the setting occupation space of this mechanism.

Referring to fig. 2a and 2b, the membrane guide mechanism of the present embodiment is used to perform high-speed lamination of wide and large cells, specifically, to perform lamination guide on a lamination table 5 for wide membranes. The lamination table 5 is kept fixed, positive plates and negative plates which are distributed at intervals and are separated by the diaphragm 6 are arranged on the diaphragm 6, after the diaphragm 6 is unreeled and passes through the fixed roller 7, the diaphragm 6 passes through the rollers from the roller passing gaps of the guide rollers 31 which are arranged in pairs and are guided to the roller assembly 3, then the guide rollers 31 which are arranged in pairs are driven by the first linear driving assembly 1 and the second linear driving assembly 2 in a synchronous high-response mode to perform high-speed lamination linear reciprocating motion along the left side and the right side, and therefore the guide diaphragm 6 is in a Z shape to perform rapid lamination. Because the first linear driving assembly 1 and the second linear driving assembly 2 perform high-response and delay-free synchronous driving on the two ends of the guide rollers 31 which are arranged in pairs, the long guide rollers 31 can always keep good stability and rigidity in the high-speed lamination linear reciprocating motion process, and the phenomenon of swinging or shaking can not occur, so that high-speed lamination of a wide and large battery cell is realized, the lamination precision is high, and the lamination efficiency of the wide and large battery cell is greatly improved. And based on the high responsiveness, high synchronism and high stability of this diaphragm guiding mechanism for the noise that produces is little in the high-speed lamination direction drive process of the big electric core of broad width based on this diaphragm guiding mechanism carries out, and machine resonance is showing and is reducing, is favorable to improving the life of machine.
