[0039] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0040] 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 1 The continuous grid structure shown. After the stamping is completed, the plate continues to move forward, so that the stamped continuous grid structure comes out of the stamping equipment, and the following 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.

[0041] 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. For this reason, the present application proposes a new continuous grid structure to solve the problem that the existing continuous grid structure is easy to deform and has low processing accuracy.

[0042] Embodiment 1:

[0043] like Figure 2 As shown, this embodiment provides a continuous grid structure, 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.

[0044] Specifically, Figure 2 As 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.

[0045] 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 first grid 110 via a first connection structure.

[0046] 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 second grid 210 via a second connection structure.

[0047] 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 third grid 310 via a third connecting structure.

[0048] like Figure 3As shown, the first connection structure in this embodiment specifically includes: a first pole ear body 510 and a second pole ear body 520. The first end of the first pole ear body 510 is integrally connected to the first grid 110, and the second end of the first pole ear body 510 is cuttable and connected to the second grid 210. The first end of the second pole ear body 520 is integrally connected to the second grid 210, and the second end of the second pole ear body 520 is cuttable and connected to the first grid 110.

[0049] The second connection structure includes: a first vertical portion 610, a transverse portion 620, and a second vertical portion 630. The first end of the first vertical portion 610 is cut and connected to the second grid 210. The first end of the transverse portion 620 is connected to the second end of the first vertical portion 610. The first end of the second vertical portion 630 is connected to the second end of the transverse portion 620, and the second end of the second vertical portion 630 is cut and connected to the third grid 310.

[0050] The third connection structure includes: a third pole ear body 710 and a fourth pole ear body 720. The first end of the third pole ear body 710 is integrally connected to the third grid 310, and the second end of the third pole ear body 710 is cuttable and connected to the fourth grid 410. The first end of the fourth pole ear body 720 is integrally connected to the fourth grid 410, and the second end of the fourth pole ear body 720 is cuttable and connected to the third grid 310.

[0051] In this embodiment, the specific structure of the second connection structure can be the same as the connection structure of the second row of grids and the third row of grids in the prior art continuous grid. However, this embodiment improves the connection structure of the first row of grids and the second row of grids, and the connection structure of the third row of grids and the fourth row of grids in the continuous grid.

[0052] Specifically, the first connection structure of the present embodiment includes two parallel first pole ear bodies 510 and second pole ear bodies 520, and two parallel third pole ear bodies 710 and fourth pole ear bodies 720. Compared with two directly connected pole ear bodies, the two parallel pole ear bodies can effectively shorten the width of the continuous grid, which can reduce the width by about 30 mm. Since the width of the continuous grid is reduced, the size of the subsequent processing equipment of the continuous grid can also be reduced, and then subsequent processing equipment with higher processing accuracy can be used, which ultimately makes the subsequent processing accuracy of the grid higher. In addition, compared with the two directly connected pole ear bodies, the parallel pole ear bodies have a shorter connection length and are less likely to deform, which ultimately makes the deformation of the subsequent grid small.

[0053] Embodiment 2:

[0054] This embodiment is further improved on the basis of Embodiment 1, specifically:

[0055] like Figure 4As shown, the second grid 210 of this embodiment includes a second grid frame, the second grid frame is provided with a first groove 211, and the first vertical portion 610 is connected to the second grid frame through the first groove 211. The first groove 211 is similar to being obtained by partially bending the second grid frame. The first groove 211 can accommodate part of the first vertical portion 610, so that the distance between the second grid 210 and the third grid 310 is shorter.

[0056] 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 second groove 311, and the second vertical portion 630 is connected to the third grid frame through the second groove 311. The second groove 311 is similar to being obtained by partially bending the third grid frame, and the second groove 311 can accommodate part of the second vertical portion 630, further shortening the distance between the second grid 210 and the third grid 310.

[0057] In summary, the arrangement of the first groove 211 and the second groove 311 can reduce the spacing between the second grid row 200 and the third grid row 300, thereby reducing the overall width of the continuous grid. When the overall width of the continuous grid is reduced, a smaller subsequent processing device can be used, thereby increasing the subsequent processing accuracy of the grid.

[0058] In addition, the width of the first groove 211 is greater than the width of the first vertical portion 610 , that is, the first vertical portion 610 is only connected to a portion of the groove body in the width direction of the first groove 211 . This arrangement facilitates subsequent cutting of the first vertical portion 610 and the first groove 211 .

[0059] The width of the second groove 311 is greater than the width of the second vertical portion 630 , that is, the second vertical portion 630 is only connected to a portion of the groove body in the width direction of the second groove 311 . This arrangement facilitates subsequent cutting of the second vertical portion 630 and the second groove 311 .

[0060] Furthermore, the first grid 110 of the present embodiment includes a first grid frame, the first grid frame is provided with a third groove, and the second pole ear body 520 is connected to the first grid frame through the third groove. The second grid frame is also provided with a fourth groove, and the first pole ear body 510 is connected to the second grid frame through the fourth groove. The third groove is similar to being obtained by partially bending the first grid frame from the view, and the fourth groove is similar to being obtained by partially bending the second grid frame from the view. The third groove can accommodate part of the second pole ear body 520, and the fourth groove can accommodate part of the first pole ear body 510.

[0061] The fourth grid 410 includes a fourth grid frame, the fourth grid frame is provided with a fifth groove, and the third tab body 710 is connected to the fourth grid through the fifth groove. Figure 6 As shown, the third grid frame is further provided with a sixth groove 312, and the fourth pole ear body 720 is connected to the third grid through the sixth groove 312. The fifth groove is similar to being obtained by partially bending the fourth grid frame, and the sixth groove 312 is similar to being obtained by partially bending the third grid frame. The fifth groove can accommodate part of the third pole ear body 710, and the sixth groove 312 can accommodate part of the fourth pole ear body 720.

[0062] The setting of the third groove and the fourth groove makes the distance between the first grid 110 and the second grid 210 shorter, and the setting of the fifth groove and the sixth groove 312 makes the distance between the third grid 310 and the fourth grid 410 shorter, thereby further reducing the overall width of the continuous grid, thereby allowing the subsequent processing accuracy of the grid to be higher.

[0063] In addition, the width of the third groove is greater than the width of the second pole ear body 520, that is, the second pole ear body 520 is only connected to a portion of the groove body in the width direction of the third groove. This arrangement facilitates subsequent cutting of the second pole ear body 520 and the third groove.

[0064] The width of the fourth groove is greater than that of the first tab body 510 , that is, the first tab body 510 is only connected to a portion of the groove body in the width direction of the fourth groove. This arrangement facilitates subsequent cutting of the first tab body 510 and the fourth groove.

[0065] The width of the fifth groove is greater than the width of the third tab body 710 , that is, the third tab body 710 is connected to a portion of the groove body in the width direction of the fifth groove. This arrangement facilitates subsequent cutting of the third tab body 710 and the fourth groove.

[0066] The width of the sixth groove 312 is greater than the width of the fourth tab body 720 , that is, the fourth tab body 720 is connected to a portion of the sixth groove 312 in the width direction. This arrangement facilitates subsequent cutting of the fourth tab body 720 and the sixth groove 312 .

[0067] 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.
