[0029] The present invention is further described in detail below in conjunction with specific embodiments: The present invention is further described in detail below in conjunction with specific embodiments: like Figure 1 As shown, a cutting method mainly adopts a cutting structure composed of a first cutter 1 and a second cutter 2 which are arranged in close contact to perform an action; the first cutter 1 has a first blade portion 11, and the first blade portion 11 has a mounting area 101 for the cutting linear body 003 to be abutted; the second cutter 2 includes a connecting portion 201 and a cutting portion 202, the cutting portion 202 is arranged to protrude from the connecting portion 201 in the length direction of the first blade portion 11, and the cutting portion 202 has a second blade portion 21.

[0030] Based on the above cutting structure, in one embodiment, combined with Figure 1 As shown, the cutting method is as follows: S1. In the initial state, set the working height, as follows Figure 1 As shown by the dotted line in the figure, the cutting linear body 003 is at the working height, the first blade portion 11 and the second blade portion 21 are on the same side of the cutting linear body 003, and are a certain distance away from the cutting linear body 003 in height, that is: the first blade portion 11 and the second blade portion 21 are below the working height, the first blade portion 11 faces the cutting linear body 003, the second blade portion 21 faces away from the cutting linear body 003, and the second blade portion 21 is on the side of the first blade portion 11 facing away from the cutting linear body 003.

[0031] S2, the second blade portion 21 moves along the first path 001 to the side of the first blade portion 11 facing the cutting linear body 003, so that the second blade portion 21 and the first blade portion 11 are arranged opposite to each other, and the vertical height between the two is greater than the height of the cutting linear body 003; and the orthographic projection of the second blade portion 21 in the length direction of the first blade portion 11 and the orthographic projection of the cutting linear body 003 in the length direction of the first blade portion 11 do not overlap; it should be noted that the definition of "first path 001" is the moving path of the second blade portion 21 relative to the first blade portion 11, and the first path 001 can be a combination of at least a single straight path and / or at least a single arc path. The traversal area of ​​the second blade portion 21 moving along the first path 001 covers the loading area 101 on the first blade portion 11. At this time, since the first blade portion 11 and the second blade portion 21 are both below the working height, the cutting linear body 003 is not in the mounting area 101 , so in this state the movement of the second blade portion 21 along the first path 001 does not interfere with the cutting linear body 003 .

[0032] S3, the cutting structure and the cutting linear body 003 move relative to each other. In this embodiment, the cutting structure moves toward the cutting linear body 003, that is, the first cutter 1 and the second cutter 2 move synchronously, so that the first blade 11 reaches the working height and the second blade 21 is higher than the working height; at this time, the second blade 21 moves to the side facing the cutting linear body 003, and the cutting linear body 003 is against the mounting area 101 of the first blade 11. During this movement, since the orthographic projections of the second blade 21 and the cutting linear body 003 in the length direction of the first blade 11 do not overlap, the first cutter 1 and the second cutter 2 will not interfere with the cutting linear body 003 during the lifting process.

[0033] S4, the second blade 21 moves in the opposite direction along the first path 001. Since the traversal area of ​​the second blade 21 along the first path 001 covers the loading area 101, the second blade 21 will pass through the cutting linear body 003, thereby completing the cutting of the cutting linear body 003. It should be noted that in order to ensure that the cutting linear body 003 can be cut smoothly, the length of the second blade 21 is not less than the width of the cutting linear body 003. The above S1-S4 completes a cutting cycle, combined with Figure 1 As shown, during the cutting cycle, the cutting linear body 003 can always be at the same height, and the first cutter 1 and the second cutter 2 can complete the cutting action.

[0034] In another embodiment, in combination Figure 2 As shown, the cutting method is as follows: S1. Set the working height, as follows Figure 2 As shown by the dotted line in the figure, in the initial state, the cutting linear body 003 is above the working height, the first blade portion 11 and the second blade portion 21 are on the same side of the cutting linear body 003, and are a certain distance in height from the cutting linear body 003. At this time, the first blade portion 11 is at the working height, and the second blade portion 21 is below the working height. Specifically, the first blade portion 11 faces the cutting linear body 003, the second blade portion 21 faces away from the cutting linear body 003, and the second blade portion 21 is on the side of the first blade portion 11 facing away from the cutting linear body 003.

[0035] S2, the second blade portion 21 moves along the first path 001 to the side of the first blade portion 11 facing the cutting linear body 003, so that the second blade portion 21 and the first blade portion 11 are arranged opposite to each other, and the vertical height between the two is greater than the height of the cutting linear body 003; and the orthographic projection of the second blade portion 21 in the length direction of the first blade portion 11 and the orthographic projection of the cutting linear body 003 in the length direction of the first blade portion 11 do not overlap; the traversal area of ​​the second blade portion 21 moving along the first path 001 covers the carrying area 101 on the first blade portion 11. At this time, since the cutting linear body 003 is above the working height and is not in the carrying area 101, the movement of the second blade portion 21 along the first path 001 in this state will not interfere with the cutting linear body 003.

[0036] S3. Relative movement occurs between the cutting structure and the cutting linear body 003. In this embodiment, the cutting linear body 003 moves toward the cutting structure, that is, the cutting linear body 003 moves downward to the mounting area 101 and reaches the working height. In this state, the second blade portion 21 faces one side of the cutting linear body 003, and the cutting linear body 003 is against the mounting area 101 of the first blade portion 11.

[0037] S4, the second blade 21 moves in the opposite direction along the first path 001. Since the traversal area of ​​the second blade 21 along the first path 001 covers the loading area 101, the second blade 21 will pass through the cutting linear body 003, thereby completing the cutting of the cutting linear body 003. It should be noted that in order to ensure that the cutting linear body 003 can be cut smoothly, the length of the second blade 21 is not less than the width of the cutting linear body 003. The above S1-S4 completes a cutting cycle, combined with Figure 1 As shown, during the cutting cycle, the first blade portion 11 is always at the same height, and the cutting of the linear body 003 can be achieved based on the movement of the second cutter 2 and the cutting linear body 003.

[0038] In other embodiments, in step S3 , “relative movement between the cutting structure and the cutting linear body 003 ” may also mean that the cutting structure and the cutting linear body 003 synchronously move toward each other until the cutting linear body 003 abuts against the mounting area 101 of the first blade portion 11 .

[0039] Based on the disclosure of the above-mentioned embodiments, in the present application, it can be used not only for cutting a single cutting linear body 003, but also for cutting multiple cutting linear bodies 003. At this time, multiple second cutters 2 need to be set. In order to ensure that multiple cutting linear bodies 003 can be cut synchronously, the number of second cutters 2 / second blade portions 21 is not less than the number of cutting linear bodies 003; multiple second blade portions 21 are distributed along the length direction of the first blade portion 11. At the same time, combined with the relative movement of the first cutter 1 and the second cutter 2, it can be seen that when multiple second cutters 2 are set, in order to avoid interference between the second cutter 2 and the cutting linear body 003, the width of the overall structure of the protruding first blade portion 11 after the second cutter 2 moves along the first path 001 is less than the distance between adjacent cutting linear bodies 003.

[0040] As for the number of the first blade portions 11, a single continuous first blade portion 11 may be used, or a plurality of first blade portions 11 arranged in segments may be used. It is only necessary to ensure that a carrying area 101 for carrying the cut linear body 003 can be formed on the first blade portion 11.

[0041] Based on the above cutting method, the present application also discloses a cutting structure, such as Figure 3 , Figure 4 As shown, it includes a first cutter 1, a second cutter 2, and a cutting drive module 3.

[0042] like Figure 5 , Figure 7 As shown, the first cutter 1 has a first blade portion 11, the first blade portion 11 is arranged along a preset first direction, and the first blade portion 11 has a mounting area 101 for the cutting linear body 003 to abut against; Figure 5 As shown, the first cutter 1 is fixed on a base 12 , and a cavity 121 is formed on the base 12 . The first cutter 1 is fixed in the cavity 121 , and the first blade portion 11 protrudes out of the cavity 121 .

[0043] like Figure 5 , Figure 6 As shown, the second cutter 2 is mounted on the first movable plate 22, fixedly connected or integrally formed with the first movable plate 22, and accommodated in the cavity 121. The second cutter 2 includes a connecting portion 201 and a cutting portion 202, the cutting portion 202 is arranged protruding from the connecting portion 201 in the length direction (first direction) of the first blade portion 11, and the cutting portion 202 has a second blade portion 21; in this embodiment, the second cutter 2 is constructed as an L-shaped structure, of course, in other embodiments, the second cutter 2 can also be sickle-shaped, T-shaped, etc., but it must be ensured that the second cutter 2 has a second blade portion 21 arranged downward in the direction shown in the figure; thereby, it can be ensured that the first blade portion 11 and the second blade portion 21 can achieve cutting of the cutting linear body 003 during the relative movement and staggering process.

[0044] In this embodiment, combined with Figure 7 , Figure 8 As shown, there are multiple second cutters 2 arranged along the length direction of the first cutter 1, that is, the second blades 21 of the multiple second cutters 2 are distributed along the first direction, and the width a of each second cutter 2 is smaller than the distance b between two adjacent mounting areas 101, so that the second cutter 2 can move upward through the space between two adjacent cutting linear bodies 003, avoiding interference between the second cutter 2 and the cutting linear body 003. Of course, combined with Figure 8 As shown, in the application scenario, the second cutter 2 does not completely move above the first cutter 1 , so it is only necessary to ensure that the width of the overall structure of the second cutter 2 protruding above the first blade portion 11 is smaller than the distance between two adjacent mounting areas 101 .

[0045] like Figure 3-Figure 5 As shown, the cutting drive module 3 is connected to the second cutter 2 to drive the second cutter 2 to reciprocate along the first path 001 , and the traversal area of ​​the second blade portion 21 moving along the first path 001 covers the loading area 101 .

[0046] Specifically, the cutting drive module 3 includes a guide member 31 , a stop member 32 , and a drive member 33 .

[0047] like Figure 5 , Fig. 9 As shown, the guide member 31 is fixedly connected with the second cutter 2 in a direct or indirect manner. In this embodiment, the guide member 31 is fixedly connected or integrally formed with the first movable plate 22, thereby realizing an indirect fixed connection between the guide member 31 and the second cutter 2. The movement of the second cutter 2 can be realized by the movement of the guide member 31. The guide member 31 has a first guide groove 34 and a second guide groove 35. The first guide groove 34 is parallel to the length direction of the first cutter 1, and at least part of the second guide groove 35 is arranged along an inclined direction. In this embodiment, the second guide groove 35 includes an upper guide groove 351 and a lower guide groove 352; the length direction of the upper guide groove 351 is perpendicular to the first direction, and the lower guide groove 352 is arranged along an inclined direction, and an obtuse angle is formed between the length directions of the upper guide groove 351 and the lower guide groove 352.

[0048] like Figure 5 As shown, the stopper 32 is relatively fixed to the first cutter 1 and accommodated in the second guide groove 35. In this embodiment, the stopper 32 is fixed to the base 12, has a columnar structure, and extends into the second guide groove 35. The stopper 32 can slide relatively in the second guide groove 35.

[0049] like Fig. 9 , Fig.10As shown, the output end of the driving member 33 has a toggle member 332 that performs circular motion. The toggle member 332 is a columnar structure and is accommodated in the first guide groove 34. The toggle member 332 can slide relatively in the first guide groove 34. The driving member 33 adopts a combination of a motor and a reducer, and is fixedly connected to the base 12 through a frame. The output end of the driving member 33 is connected to a rotating shaft 331 that rotates along the central axis, and the toggle member 332 is eccentrically installed relative to the central axis of the rotating shaft 331.

[0050] In general, in the present application, the connecting ends of the toggle member 332 and the stopper member 32 are arranged on different sides of the guide member 31, and the connecting end of the stopper member 32 is fixed on the base 12 and extends from one side of the base 12 to the second guide groove 35. The connecting end of the toggle member 332 is arranged on the rotating shaft 331 and extends from one side of the rotating shaft 331 to the first guide groove 34, and the base 12 and the rotating shaft 331 are arranged on both sides of the guide member 31. Furthermore, based on the action of the driving member 33, the toggle member 332 can drive the guide member 31 to move, and due to the cooperation between the stopper member 32 and the second guide groove 35, the guide member 31 can only move according to the rated movement path (first path 001).

[0051] In the present application, since the second cutter 2 will move relative to the first cutter 1, a guide assembly must also be provided, and thus a first guide assembly 100 and a second guide assembly 200 are indirectly provided between the first cutter 1 and the second cutter 2; the first guide assembly 100 is provided in parallel with the first direction; and the second guide assembly 200 is provided in perpendicular to the first direction.

[0052] In this embodiment, the second guide groove 35 includes an upper guide groove 351 and a lower guide groove 352; Fig.12 As shown, when the toggle member 332 is in the first guide slot 34 and the stopper 32 is in the upper guide slot 351, the second cutter 2 moves only along the second guide assembly 200, that is, it moves in the vertical direction. Fig.12 Between the state (b) and the state (c), the second cutter 2 moves only in the vertical direction; when the toggle member 332 is in the first guide groove 34 and the stopper 32 is in the lower guide groove 352, the second cutter 2 moves synchronously along the first guide assembly 100 and the second guide assembly 200, that is, it moves obliquely. Fig.12 Between the state (a) and the state (b), the second cutter 2 moves obliquely.

[0053] As for the specific connection method, the second movable plate 23 is installed on the first movable plate 22 or the guide member 31, and the first guide assembly 100 is used for connection. Mainly because the first movable plate 22 is fixedly connected to the guide member 31, the second movable plate 23 can be directly and movably connected to the first movable plate 22, and can also be directly and movably connected to the guide member 31; the second movable plate 23 is directly or indirectly connected to the first cutter 1 through the second guide assembly 200, and because the first cutter 1 is fixed on the base 12, the second movable plate 23 can be movably connected to the base 12. Specifically, as Figure 4 As shown, in this embodiment, a first guide assembly 100 distributed along the first direction is arranged between the second movable plate 23 and the guide member 31, a second guide assembly 200 distributed perpendicular to the first direction is arranged between the second movable plate 23 and the base 12, and the second guide assembly 200 is arranged on both side end surfaces of the cavity 121 along the first direction.

[0054] Since in one cutting mode, "relative movement between the cutting structure and the cutting linear body 003" means that the first cutting knife 1 and the second cutting knife 2 are synchronously lifted, in this embodiment, Figure 3 , Figure 4 As shown, the cutting structure also includes a lifting drive module 4, which can use a lifting cylinder to drive the first cutter 1, the second cutter 2 and the cutting drive module 3 to rise and fall synchronously; the output end of the lifting drive module 4 is directly or indirectly fixedly connected to the base 12.

[0055] In detail, the base 12 is mounted on the lifting plate 13, and the output end of the lifting drive module 4 is fixedly connected to the lifting plate 13. In addition, by setting the frame 14, a third guide assembly 300 is provided between the lifting plate 13 and the frame 14 to achieve the guidance of the lifting movement.

[0056] In the application scenario, since the first cutter 1 and the second cutter 2 are used to cut the cutting linear body 003, the cutting linear body 003 in this application is a "welding strip".
