Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work all belong to the protection scope of the present invention.
As shown in fig. 1-8, the utility model provides a production facility of a clamping and stacking type laminated battery, which comprises a liftable workbench 1, a diaphragm fixing roller 2, a diaphragm conveying roller 3, two pressing mechanisms 4 and two grabbing mechanisms 5; the diaphragm fixing roller 2 is fixedly arranged on the workbench 1 and used for fixing one end of a diaphragm; the diaphragm conveying roller 3 is fixedly arranged above the workbench 1 and used for unreeling the diaphragm.
The two pressing mechanisms 4 are oppositely and alternately arranged on two sides of the workbench 1, each pressing mechanism comprises two pressing parts which are arranged at intervals, and the pressing parts of the two pressing mechanisms 4 are arranged above the workbench 1 in a staggered manner; on one hand, the two pressing mechanisms horizontally carry out staggered shaping on the diaphragm, so that the diaphragm is provided with a plurality of conical protruding parts; on the other hand, the positive plate or the negative plate fed by the grabbing mechanism 5 is vertically pressed with the diaphragm.
The two grabbing mechanisms 5 are oppositely arranged on two sides of the workbench 1; the grabbing mechanism 5 is used for grabbing the positive plate 100 or the negative plate 200, bending the positive plate 100 or the negative plate 200 along the central line and sending the bent positive plate 100 or the bent negative plate 200 into an area between two pressing parts of a pressing mechanism, so that the surface of the positive plate 100 or the negative plate 200 is abutted to the surface of the diaphragm; the grabbing mechanism 5 is used for grabbing the positive plate 100 or the negative plate 200 from a pole piece box for placing the positive plate or the negative plate, pre-shaping the positive plate 100 or the negative plate 200, namely, bending the positive plate 100 or the negative plate at a certain angle and then sending the bent plate into a region between two pressing parts arranged at intervals of the pressing mechanism, and because the width of the positive plate 100 or the negative plate 200 shown in the figure is large, the plate cannot be placed between the pressing parts and abutted against a diaphragm without being bent, and the attaching area of the plate and the diaphragm cannot be increased.
Wherein, each pressing part of the pressing mechanism moves towards the upper surface direction of the workbench 1 respectively to press the positive plate 100 or the negative plate 200 and the diaphragm. As can be seen from the figure, every time a group of positive plates and negative plates are pressed in a clamping and laminating manner, the lamination on the upper surface of the workbench 1 can be increased by a certain height, and the overall height of the two pressing mechanisms 4 and the two grabbing mechanisms 5 cannot be changed along with the whole height, so that after one section of the positive plate, the negative plate and the diaphragm are pressed in each pressing manner, the workbench descends by a certain height, and the two pressing mechanisms 4 and the two grabbing mechanisms 5 cannot interfere with the pressed positive plate, the pressed negative plate and the diaphragm. After the positive electrode sheet 100 or the negative electrode sheet 200 is pressed with the separator, the whole pressed separator is bent in an S shape, and the positive electrode sheet 100 or the negative electrode sheet 200 is approximately in a U shape, so as to be integrally attached to the bent part of the separator and further extend to the surface of the non-bent part of the separator.
As shown in fig. 2 to 4 and fig. 8, two pressing mechanisms 4, for distinguishing the marks, are denoted by 4A and 4B, each of the pressing mechanisms 4A and 4B includes a first pressing portion 41 and a second pressing portion 42, which are independent of each other, and the distance between the first pressing portion 41A and the second pressing portion 42A of the pressing mechanism 4A is adjustable, and similarly, the distance between the first pressing portion 41B and the second pressing portion 42B of the pressing mechanism 4B is adjustable. The first pressing parts 41 and the second pressing parts 42 of the two pressing mechanisms 4 are arranged in a staggered manner, that is, the pressing parts 41A, 41B, 42A and 42B are arranged in a staggered manner, so that the diaphragm passing through the two pressing mechanisms 4A and 4B sequentially forms a first bending part 101, a second bending part 102, a third bending part 103 and a fourth bending part 104 from bottom to top; the second bent portion 102 is located between the first pressing portion 41A and the second pressing portion 42A; the third bent portion 103 is located between the first pressing portion 41B and the second pressing portion 42B, and as can be seen from the figure, the second bent portion 102 and the third bent portion 103 have an isosceles tapered structure and have the largest inclined membrane attachment area. When the grasping mechanism 5 grasps the bent positive electrode sheet 100 or negative electrode sheet 200 to make the shape of the positive electrode sheet 100 or negative electrode sheet 200 similar to the second bent part 102 or third bent part 103, the grasping mechanism 5 further abuts the positive electrode sheet 100 or negative electrode sheet 200 against the separator at the second bent part 102 or third bent part 103; the first pressing portion 41 and the second pressing portion 42 are vertically moved toward the upper surface of the table 1. In order to fix the position of the positive plate 100 or the negative plate 200 and prevent the positive plate 100 or the negative plate 200 from sliding relative to the separator, an adhesive area may be preset at the edge position of the blank area of the positive plate 100 or the negative plate 200, so as to perform pre-positioning with the separator better, and the positive plate or the negative plate will not be separated from the separator even if the grabbing mechanism 5 is removed.
