[0002] In the field of photovoltaic cell manufacturing in the semiconductor industry, welding multiple cell wafers with solder tapes is a key process operation. During this process, precise cutting of the solder tapes plays a crucial role in ensuring the welding quality and production efficiency of the cell wafers.

[0003] Currently, there are various deficiencies in the existing solder tape cutting technologies. On the one hand, when some cutting devices are not in operation, their cutting components cannot be hidden and are exposed around the solder tapes. This not only easily causes interference with other components during production, affecting the normal operation of the equipment, but also may cause accidental damage to the solder tapes, thereby reducing the quality and usability of the solder tapes. On the other hand, there are also certain defects in the drive systems of the existing solder tape cutting devices. Some drive systems have complex structures, high costs, and great maintenance difficulties, requiring professional technicians for operation and maintenance. At the same time, the stability and reliability of some drive systems are poor, prone to failures, and affecting the continuity and stability of production. Summary of the Invention

[0075] The present invention is further described in detail below in conjunction with specific embodiments:

[0076] The present invention is further described in detail below in conjunction with specific embodiments:

[0077] like Figure 1As shown, a cutting method mainly performs actions using a cutting structure composed of a first cutter 1 and a second cutter 2 arranged in a fitting manner; 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 abut against; the second cutter 2 includes a connecting portion 201 and a cutting portion 202, the cutting portion 202 protrudes 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.

[0078] Based on the above cutting structure, in one embodiment, in combination with Figure 1 as shown, the cutting method is as follows:

[0079] S1. In the initial state, set the working height, specifically as shown by the dotted line in Figure 1 , 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 there is a certain distance 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.

[0080] 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 relatively, 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 does not coincide with the orthographic projection of the cutting linear body 003 in the length direction of the first blade portion 11; it should be noted that the definition of the "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 adopt a combination of at least a single-segment straight line path and / or at least a single-segment arc path. The traversal area of the second blade portion 21 moving along the first path 001 covers the mounting area 101 on the first blade portion 11. At this time, since both the first blade portion 11 and the second blade portion 21 are below the working height and the cutting linear body 003 is not in the mounting 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.

[0081] S3. Relative movement occurs between the cutting structure and the cutting wire body 003. In this embodiment, the cutting structure moves towards the cutting wire body 003, that is, the first cutter 1 and the second cutter 2 perform synchronous lifting movements, so that the first cutting edge 11 reaches the working height, and the second cutting edge 21 is higher than the working height. At this time, the second cutting edge 21 moves to the side facing the cutting wire body 003, and the cutting wire body 003 abuts on the carrying area 101 of the first cutting edge 11. During this movement process, since there is no overlap between the orthographic projections of the second cutting edge 21 and the cutting wire body 003 in the length direction of the first cutting edge 11, the first cutter 1 and the second cutter 2 will not interfere with the cutting wire body 003 during the lifting process.

[0082] S4. The second cutting edge 21 moves in the reverse direction along the first path 001. Since the traversal area of the second cutting edge 21 moving along the first path 001 covers the carrying area 101, the second cutting edge 21 will pass through the cutting wire body 003, thereby completing the cutting of the cutting wire body 003. It should be noted that in order to ensure that the cutting wire body 003 can be smoothly cut off, the length of the second cutting edge 21 is not less than the width of the cutting wire body 003. The above S1 - S4 complete a cutting cycle. As shown in Figure 1 During this cutting cycle, the cutting wire body 003 can always be at the same height, and the cutting action can be completed by the actions of the first cutter 1 and the second cutter 2.

[0083] In another embodiment, as shown in Figure 2 The cutting method is as follows:

[0084] S1. Set the working height, as specifically shown by the dotted line in Figure 2 In the initial state, the cutting wire body 003 is above the working height. The first cutting edge 11 and the second cutting edge 21 are on the same side of the cutting wire body 003 and are at a certain distance from the cutting wire body 003 in height. At this time, the first cutting edge 11 is at the working height, and the second cutting edge 21 is below the working height. Specifically, the first cutting edge 11 faces the cutting wire body 003, the second cutting edge 21 faces away from the cutting wire body 003, and the second cutting edge 21 is on the side of the first cutting edge 11 facing away from the cutting wire body 003.

[0085] S2. The second blade part 21 moves along the first path 001 to the side of the first blade part 11 facing the cutting linear body 003, so that the second blade part 21 is arranged opposite to the first blade part 11, and the vertical height between the two is greater than the height of the cutting linear body 003; moreover, the orthographic projection of the second blade part 21 in the length direction of the first blade part 11 does not coincide with the orthographic projection of the cutting linear body 003 in the length direction of the first blade part 11; the traversal area of the second blade part 21 moving along the first path 001 covers the mounting area 101 on the first blade part 11. At this time, since the cutting linear body 003 is above the working height and not in the mounting area 101, the movement of the second blade part 21 along the first path 001 in this state will not interfere with the cutting linear body 003.

[0086] S3. Relative movement occurs between the cutting structure and the cutting linear body 003. In this embodiment, the cutting linear body 003 moves towards 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 part 21 faces the side of the cutting linear body 003, and the cutting linear body 003 abuts on the mounting area 101 of the first blade part 11.

[0087] S4. The second blade part 21 moves in the reverse direction along the first path 001. Since the traversal area of the second blade part 21 moving along the first path 001 covers the mounting area 101, the second blade part 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 smoothly cut off, the length of the second blade part 21 is not less than the width of the cutting linear body 003. The above S1 - S4 complete a cutting cycle. As shown in Figure 1 In the shown figure, during this cutting cycle, the first blade part 11 is always at the same height. Based on the movement of the second cutter 2 and the cutting linear body 003, the cutting of the cutting linear body 003 can be realized.

[0088] In other embodiments, in step S3, "relative movement occurs between the cutting structure and the cutting linear body 003" can also be that the cutting structure and the cutting linear body 003 move towards each other synchronously until the cutting linear body 003 abuts on the mounting area 101 of the first blade part 11.

[0089] 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.

[0090] 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.

[0091] 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.

[0092] 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 .

[0093] 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.

[0094] In this embodiment, in combination with Figure 7 , Figure 8 As shown, there are multiple second cutting knives 2, which are arranged along the length direction of the first cutting knife 1, that is, the second cutting edges 21 of the multiple second cutting knives 2 are distributed in the first direction. The width a of each second cutting knife 2 is less than the distance b between two adjacent loading areas 101. Furthermore, the second cutting knife 2 can move upward through the space between two adjacent cut wire bodies 003, avoiding interference between the second cutting knife 2 and the cut wire body 003. Of course, in combination with Figure 8 As shown, in the application scenario, the second cutting knife 2 does not completely move above the first cutting knife 1. Therefore, it is only necessary to ensure that the width of the overall structure where the second cutting knife 2 protrudes above the first cutting edge 11 is less than the distance between two adjacent loading areas 101.

[0095] As Figures 3 - 5 shown, the cutting drive module 3 is connected to the second cutting knife 2, driving the second cutting knife 2 to reciprocate along the first path 001, and the traversing area where the second cutting edge 21 moves along the first path 001 covers the loading area 101.

[0096] Specifically, the cutting drive module 3 includes a guide member 31, a stop member 32, and a driving member 33.

[0097] As Figure 5 , Figure 9 shown, the guide member 31 is fixedly connected to the second cutting knife 2 directly or indirectly. In this embodiment, the guide member 31 is fixedly connected to or integrally formed with the first movable plate 22, thereby realizing the indirect fixed connection between the guide member 31 and the second cutting knife 2. The movement of the second cutting knife 2 can be realized through 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 cutting knife 1, and at least part of the second guide groove 35 is arranged in 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, the lower guide groove 352 is arranged in 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.

[0098] As Figure 5 shown, the stop member 32 is relatively fixed to the first cutting knife 1 and is accommodated in the second guide groove 35. In this embodiment, the stop member 32 is fixed on the base 12, has a cylindrical structure, and extends into the second guide groove 35. The stop member 32 can slide relatively in the second guide groove 35.

[0099] As Figure 9 , Figure 10As shown, the output end of the driving member 33 has a toggling member 332 that moves in a circular motion. The toggling member 332 has a cylindrical structure and is accommodated in the first guiding groove 34. The toggling member 332 can slide relative to the first guiding groove 34. The driving member 33 is 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. The toggling member 332 is eccentrically installed relative to the central axis of the rotating shaft 331.

[0100] Generally speaking, in this application, the connecting ends of the toggling member 332 and the stopper 32 are respectively located on different sides of the guiding member 31. The connecting end of the stopper 32 is fixed on the base 12 and extends from one side of the base 12 into the second guiding groove 35. The connecting end of the toggling member 332 is arranged on the rotating shaft 331 and extends from one side of the rotating shaft 331 into the first guiding groove 34. The base 12 and the rotating shaft 331 are respectively located on both sides of the guiding member 31. Furthermore, based on the action of the driving member 33, the toggling member 332 can drive the guiding member 31 to move. Due to the cooperation between the stopper 32 and the second guiding groove 35, the guiding member 31 can only move along a rated movement path (the first path 001).

[0101] In this application, since the second cutter 2 will move relative to the first cutter 1, a guiding assembly must be provided. Therefore, there are an indirectly arranged first guiding assembly 100 and a second guiding assembly 200 between the first cutter 1 and the second cutter 2. The first guiding assembly 100 is arranged parallel to the first direction. The second guiding assembly 200 is arranged perpendicular to the first direction.

[0102] Since in this embodiment, the second guiding groove 35 includes an upper guiding groove 351 and a lower guiding groove 352; therefore, in combination with Figure 12 As shown, when the toggling member 332 is in the first guiding groove 34 and the stopper 32 is in the upper guiding groove 351, the movement makes the second cutter 2 move only relative to the second guiding assembly 200, that is, move in the vertical direction, which is Figure 12 between the states (b) and (c) in Figure 12 where the second cutter 2 only moves vertically; when the toggling member 332 is in the first guiding groove 34 and the stopper 32 is in the lower guiding groove 352, the movement makes the second cutter 2 move synchronously along the first guiding assembly 100 and the second guiding assembly 200, that is, move obliquely, which is

[0103] Regarding the specific connection method, a second movable plate 23 is installed on the first movable plate 22 or the guide member 31, and the first guiding assembly 100 is used for connection. Since the first movable plate 22 is fixedly connected to the guide member 31, the second movable plate 23 can be directly movably connected to the first movable plate 22 or directly movably connected to the guide member 31; the second movable plate 23 is directly or indirectly connected to the first cutting knife 1 through the second guiding assembly 200. Since the first cutting knife 1 is fixed on the base 12, the second movable plate 23 can be movably connected to the base 12. Specifically, as Figure 4 shown, in this embodiment, a first guiding assembly 100 distributed along the first direction is provided between the second movable plate 23 and the guide member 31, and a second guiding assembly 200 distributed perpendicular to the first direction is provided between the second movable plate 23 and the base 12, and the second guiding assembly 200 is provided on both end faces of the cavity 121 along the first direction.

[0104] In one cutting mode, "relative movement occurs between the cutting structure and the cut wire body 003" means that the first cutting knife 1 and the second cutting knife 2 perform synchronous lifting movements. Therefore, in this embodiment, as Figure 3 、 Figure 4 shown, the cutting structure further includes a lifting drive module 4. The lifting drive module 4 can adopt a lifting cylinder to drive the first cutting knife 1, the second cutting knife 2 and the cutting drive module 3 to lift and lower synchronously; the output end of the lifting drive module 4 is directly or indirectly fixedly connected to the base 12.

[0105] Specifically, the base 12 is installed on the lifting plate 13, and the output end of the lifting drive module 4 is fixedly connected to the lifting plate 13. And by providing a frame 14, a third guiding assembly 300 is provided between the lifting plate 13 and the frame 14 to realize the guiding of the lifting movement.

[0106] In the application scenario, since the first cutting knife 1 and the second cutting knife 2 are used to cut the cut wire body 003, and the cut wire body 003 in this application is a "welding tape", in order to ensure that the welding tape can accurately abut on the carrying area 101, as Figure 11 shown, a drainage component 5 is also fixedly installed above the frame 14. The drainage component 5 is located on the side of the first cutting knife 1 away from the second cutting knife 2; the drainage component 5 has a drainage groove 53 through which the material passes, and the material passing through the drainage groove 53 is carried on the carrying area 101 of the first cutting knife 1.

[0107] Specifically, the drainage component 5 includes a drainage plate 51 and a cover plate 52, and the drainage groove 53 is formed on the upper end face of the drainage plate 51 and / or the lower end face of the cover plate 52. The width of the drainage groove 53 gradually increases from the side close to the first cutting knife 1 to the side away from the cutting knife.

[0108] Based on the above cutting method and cutting structure, the present application mainly realizes the movement of the guiding member 31 along the central trajectory of the second guiding groove 35 through the mutual cooperation among the guiding member 31, the stopping member 32, and the driving member 33 with a single power source, and further realizes the reciprocating movement of the second cutter 2 along a predetermined trajectory. Moreover, during the reset process of the second cutter 2, reasonable avoidance with the cut linear body 003 can be achieved, and the movement is simple and ingenious. During the working process, in the non-cutting state, the cutting structure can be completely hidden under the cut linear body 003 without interfering with other process operations.
