[0026] Beneficial Effects
[0027] The continuous grid of the embodiment of the present specification has a first grid row and a second grid row connected by a single first pole ear body. Compared with the connection arrangement of two pole ear bodies, the width of the continuous grid can be shortened, so that the subsequent processing of the continuous grid can use smaller processing equipment, which can ultimately improve the subsequent processing accuracy of the grid; and compared with the two directly connected pole ear bodies, the connection length of the single pole ear body is shorter and less prone to deformation, which ultimately reduces the deformation of the subsequent grid.
[0028] Further or more detailed beneficial effects will be described in detail in conjunction with specific examples in the specific implementation manner. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.
[0036] In the prior art, the method for making a grid is generally as follows: first, a portion of a roll of plate is fed into a stamping device, and the stamping device stamps the portion of the plate located inside it into a shape such as Figure 6 The continuous grid structure shown in the figure. After the stamping is completed, the plate continues to move forward, so that the stamped part of the continuous grid comes out of the stamping equipment, and the remaining part of the plate enters the stamping equipment for stamping. The continuous grid coming out of the stamping equipment will also undergo subsequent processing (such as coating with lead paste), and after the subsequent processing, the continuous grid will be cut to obtain a single grid.
[0037] Since the existing continuous grid is relatively wide, the size of the subsequent processing equipment is relatively large, and the processing accuracy of the large-sized processing equipment is relatively low, which makes the processing accuracy of the final grid relatively low. In addition, in the existing continuous grid, the grid plates are directly connected to each other through two tab bodies, and the connection is long and easy to deform. Therefore, the present application proposes a new continuous grid structure to solve the problem that the existing continuous grid is easy to deform and has low processing accuracy.
[0038] Embodiment 1:
[0039] like Figure 1 As shown, this embodiment provides a continuous grid, including: a first grid row 100, a second grid row 200, a third grid row 300 and a fourth grid row 400. Since the width of the coil is fixed, the number of grid rows is still four.
[0040] Specifically, Figure 1As shown, the first grid row 100 includes a plurality of first grids 110. Generally, the length of the first grid row 100 is the same as the length of the coil. The number of first grids 110 on the first grid row 100 is large.
[0041] The second grid row 200 includes a plurality of second grids 210. The length of the second grid row 200 is the same as that of the first grid row 100, and the second grids 210 are arranged one-to-one with the first grids 110. Each second grid 210 is connected to the corresponding first grid 110 via a first connection structure.
[0042] The third grid row 300 includes a plurality of third grids 310. The length of the third grid row 300 is the same as that of the second grid row 200, and the third grids 310 are arranged one-to-one with the second grid row 200. Each third grid 310 is connected to the corresponding second grid 210 via a second connection structure.
[0043] The fourth grid row 400 includes a plurality of fourth grids 410. The length of the fourth grid row 400 is the same as that of the third grid row 300, and the fourth grids 410 are arranged one-to-one with the third grids 310. Each fourth grid 410 is connected to the corresponding third grid 310 via a third connecting structure.
[0044] like Figure 2 As shown, the first connection structure in this embodiment specifically includes: a first tab body 510 .
[0045] The first end of the first tab body 510 is integrally connected to the first grid 110 , and the second end of the first tab body 510 is cuttable and connected to the second grid 210 .
[0046] like Figure 3 As shown, the second connection structure in this embodiment specifically includes: a second tab body 520 and a third tab body 530 .
[0047] The first end of the second tab body 520 is integrally connected to the second grid 210 , and the second end of the second tab body 520 is cuttable and connected to the third grid 310 .
[0048] The first end of the third tab body 530 is integrally connected to the third grid 310 , and the second end of the third tab body 530 is cuttable and connected to the second grid 210 .
[0049] like Figure 4 As shown, the third connection structure in this embodiment specifically includes: a fourth electrode ear body 540 .
[0050] The first end of the fourth tab body 540 is connected to the fourth grid 410 in an integral manner, and the second end of the fourth tab body 540 is connected to the third grid 310 in a cuttable manner.
[0051] First, the first connection structure of this embodiment includes only one pole ear body (i.e., the first pole ear body 510, which serves as the pole ear body of the first grid 110). Compared with the two pole ear bodies in the prior art, the width of the continuous grid can be shortened, which can be reduced by about 15 mm (i.e., one pole ear body).
[0052] Secondly, the third connection structure of this embodiment also only includes one pole ear body (i.e., the fourth pole ear body 540, which serves as the pole ear body of the fourth grid 410). Compared with the two pole ear bodies in the prior art, the width of the continuous grid can be further shortened, which can be reduced by about 15 mm (i.e., one pole ear body).
[0053] Finally, the second connection structure of the present embodiment includes two parallel arranged second pole ear bodies 520 and third pole ear bodies 530 (the second pole ear body 520 serves as the pole ear body of the second grid 210, and the third pole ear body 530 serves as the pole ear body of the third grid 310). Compared with the second connection structure in the prior art (including a first vertical portion, a transverse portion and a second vertical portion, the first end of the first vertical portion is cuttable and connected to the second grid 210, the first end of the transverse portion is connected to the second end of the first vertical portion, the first end of the second vertical portion is connected to the second end of the transverse portion, and the second end of the second vertical portion is cuttable and connected to the third grid 310), although the second connection structure of the present embodiment does not reduce the width between the second grid 210 and the third grid 310, the second connection structure enables both the second grid 210 and the third grid 310 to have pole ear bodies.
[0054] In summary, the setting of the first connection structure and the second connection structure of this embodiment can effectively shorten the overall width of the continuous grid, which can reduce the width by about 30 mm, and the setting of the third connection structure of this embodiment can ensure that each grid has its own pole ear body. Since the overall width of the continuous grid is reduced, the size of the subsequent processing equipment of the continuous grid can also be reduced, and then the subsequent processing equipment with higher processing accuracy can be used, which ultimately makes the subsequent processing accuracy of the grid higher. In addition, there is a single pole ear body between the first grid 110 and the second grid 210 and between the third grid 310 and the fourth grid 410. Compared with the two pole ears directly connected in the existing structure, the length of the connection is shorter and less likely to deform, which ultimately makes the deformation of the subsequent grid small.
[0055] Embodiment 2:
[0056] This embodiment is further improved on the basis of Embodiment 1, specifically:
[0057] like Figure 5 As shown, the third grid 310 of this embodiment includes a third grid frame, the third grid frame is provided with a first groove 311, and the fourth pole ear body 540 is connected to the third grid frame through the first groove 311. The first groove 311 is similar to being obtained by partially bending the third grid frame. The first groove 311 can accommodate part of the fourth pole ear body 540, so that the distance between the third grid 310 and the fourth grid 410 is shorter.
[0058] In this embodiment, the width of the first groove 311 is greater than the width of the fourth pole ear body 540. The third grid 310 also includes a third grid transverse rib and a third grid vertical rib arranged inside the third grid frame, and the width direction of the first groove 311 is the same as the setting direction of the third grid transverse rib. The fourth pole ear body 540 is only connected to a portion of the groove body in the width direction of the first groove 311, and this setting facilitates the subsequent cutting of the fourth pole ear body 540 and the first groove 311 (i.e., the third grid 310).
[0059] Furthermore, the third grid frame of this embodiment is also provided with a second groove, and the second pole ear body 520 is connected to the third grid frame through the second groove. The second grid 210 includes a second grid frame, and the second grid frame is provided with a third groove, and the third pole ear body 530 is connected to the second grid frame through the third groove.
[0060] The second groove is similar to being obtained by partially bending the third grid frame, and the third groove is similar to being obtained by partially bending the second grid frame. The second groove can accommodate part of the second pole ear body 520, and the third groove can accommodate part of the third pole ear body 530. This arrangement makes the distance between the second grid 210 and the third grid 310 shorter.
[0061] In this embodiment, the width of the second groove is greater than the width of the second pole ear body 520, and the width direction of the second groove is the same as the setting direction of the third grid transverse rib. The second pole ear body 520 is only connected to a portion of the groove body in the width direction of the second groove 3, and this setting facilitates the subsequent cutting of the second pole ear body 520 and the second groove (i.e., the third grid 310).
[0062] The width of the third groove is greater than the width of the third pole ear body 530. The second grid 210 also includes a second grid transverse rib and a second grid vertical rib arranged inside the second grid frame, and the width direction of the third groove is the same as the setting direction of the second grid transverse rib. The third pole ear body 530 is only connected to a portion of the groove body in the width direction of the third groove, and this arrangement facilitates the subsequent cutting of the third pole ear body 530 and the third groove (i.e., the second grid 210).
[0063] Furthermore, the second grid frame is further provided with a fourth groove, and the first pole ear body 510 is connected to the second grid frame through the fourth groove. The fourth groove is similar to being obtained by partially bending the second grid frame from a view. The fourth groove can accommodate part of the first pole ear body 510, and this arrangement makes the distance between the first grid 110 and the second grid 210 shorter.
[0064] In this embodiment, the width of the fourth groove is greater than the width of the first pole ear body 510, and the width direction of the fourth groove is the same as the setting direction of the second grid transverse rib. The first pole ear body 510 is only connected to a portion of the groove body in the width direction of the fourth groove, and this setting facilitates the subsequent cutting of the first pole ear body 510 and the fourth groove (i.e., the second grid 210).
[0065] In summary, the arrangement of the first groove 311, the second groove, the third groove and the fourth groove can make the spacing between the first grid row 100 and the second grid row 200, the spacing between the second grid row 200 and the third grid row 300, and the spacing between the third grid row 300 and the fourth grid row 400 smaller, which will make the overall width of the continuous grid smaller. When the overall width of the continuous grid is reduced, a smaller size of subsequent processing equipment can be used, thereby making the subsequent processing accuracy of the grid higher.
[0066] Furthermore, two adjacent first connection structures are symmetrically arranged; two adjacent second connection structures are symmetrically arranged; and two adjacent third connection structures are symmetrically arranged.
[0067] like Figure 2 As shown, the first pole ear body 510 on the first first grid 110 on the left is symmetrically arranged with the first pole ear body 510 on the second first grid 110 on the left; the first pole ear body 510 on the second first grid 110 on the left is symmetrically arranged with the first pole ear body 510 on the second first grid 110 on the right; the first pole ear body 510 on the first first grid 110 on the right is symmetrically arranged with the first pole ear body 510 on the second first grid 110 on the right.
[0068] like Figure 3 As shown, the second pole ear body 520 and the third pole ear body 530 on the first second grid 210 on the left are symmetrically arranged with the second pole ear body 520 and the third pole ear body 530 on the second second grid 210 on the left; the second pole ear body 520 and the third pole ear body 530 on the second second grid 210 on the left are symmetrically arranged with the second pole ear body 520 and the third pole ear body 530 on the second second grid 210 on the right; the second pole ear body 520 and the third pole ear body 530 on the first second grid 210 on the right are symmetrically arranged with the second pole ear body 520 and the third pole ear body 530 on the second second grid 210 on the right.
[0069] like Figure 4 As shown, the fourth pole ear body 540 on the first fourth grid 410 on the left is symmetrically arranged with the fourth pole ear body 540 on the second fourth grid 410 on the left; the fourth pole ear body 540 on the second fourth grid 410 on the left is symmetrically arranged with the fourth pole ear body 540 on the second fourth grid 410 on the right; the fourth pole ear body 540 on the first fourth grid 410 on the right is symmetrically arranged with the fourth pole ear body 540 on the second fourth grid 410 on the right.
[0070] This arrangement ensures that the entire continuous grid has good structural stability, thereby further reducing the deformation of the continuous grid.
[0071] The above embodiments are only for describing the preferred implementation of the utility model, and are not intended to limit the concept and scope of the utility model. Without departing from the design concept of the utility model, various modifications and improvements made by ordinary persons in the art to the technical solution of the utility model should fall within the protection scope of the utility model, and the technical contents of the utility model for protection have been fully recorded in the claims.
