Detailed Implementation

[0041] Various exemplary embodiments of this application will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of this application.

[0042] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the scope of this application and its application or use.

[0043] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0044] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0045] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0046] First, it should be noted that the X, Y, and Z directions mentioned in the embodiments of this application are referred to in the appendix. Figure 1 , Figure 4 , Figure 5 and Figure 9 The marked directions. Among them, the axes in the X direction, Y direction, and Z direction intersect each other.

[0047] like Figures 1-9 As shown, according to a first aspect of the embodiments of this application, a cutting device 100 is provided, including a cutting mechanism 1 and a driving mechanism 2; the cutting mechanism 1 includes a first mounting component 11, a first cutting component 12 and a second cutting component 13, the first cutting component 12 and the second cutting component 13 are disposed opposite to each other and are slidably connected to the first mounting component 11; the driving mechanism 2 includes a driving component 21, a second mounting component 22, a third mounting component 23, a first elastic component 24 and a guide component 25, the driving end of the driving component 21 is connected to the second mounting component 22, the second mounting component 22 and the third mounting component 23 are connected through the first elastic component 24, the first mounting component 11 is disposed on the side of the third mounting component 23 away from the second mounting component 22, and the guide component 25 is slidably connected to the first cutting component 12 and the second cutting component 13 respectively.

[0048] The cutting device 100 in this application is suitable for cutting welding strips, and can also be used to cut other strip-shaped materials (such as metal wires). The embodiments of this application are described using the cutting of welding strips as an example.

[0049] like Figure 1 , Figure 5 and Figure 8 As shown, the cutting device 100 includes a cutting mechanism 1 and a driving mechanism 2; the cutting mechanism 1 is used to cut the welding strip, and the driving mechanism 2 is used to drive the cutting mechanism 1 to move in the Z direction, and to drive the first cutting assembly 12 and / or the second cutting assembly 13 to move in opposite directions or towards each other in the X direction to cut the welding strip.

[0050] Specifically, taking the example of the first cutting blade assembly 12 and the second cutting blade assembly 13 moving in opposite directions, the cutting blade mechanism 1 includes a first mounting assembly 11, a first cutting blade assembly 12, and a second cutting blade assembly 13; the first cutting blade assembly 12 and the second cutting blade assembly 13 are arranged opposite each other along the Y direction, the first cutting blade assembly 12 is slidably connected to the first mounting assembly 11 along the X direction, and the second cutting blade assembly 13 is slidably connected along the X direction. When the first cutting blade assembly 12 and the second cutting blade assembly 13 move in opposite directions along the X direction, the welding strip can be cut.

[0051] The drive mechanism 2 includes a drive assembly 21, a second mounting assembly 22, a third mounting assembly 23, a first elastic component 24, and a guide assembly 25. The second mounting assembly 22 is located at the drive end of the drive assembly 21, and the drive assembly 21 can drive the second mounting assembly 22 to move along the Z direction. The third mounting assembly 23 is connected to the second mounting assembly 22 through the first elastic component 24. The first mounting assembly 11 is located at the end of the third mounting assembly 23 away from the second mounting assembly 22. The guide assembly 25 is located on the side of the second mounting assembly 22 close to the third mounting assembly 23, and the guide assembly 25 is connected to the first cutter assembly 12 and the second cutter assembly 13 respectively. Therefore, when the drive assembly 21 drives the second mounting assembly 22 to move upward along the Z direction, the second mounting assembly 22 drives the third mounting assembly 23 to move upward along the Z direction, thereby driving the first mounting assembly 11 to move upward along the Z direction. Thus, the cutter mechanism 1 will move upward along the Z direction accordingly. When the cutting mechanism 1 moves upward in the Z direction to a preset position, the third mounting component 23 will no longer move in the Z direction, and the cutting mechanism 1 will no longer move in the Z direction. The driving component 21 continues to drive the second mounting component 22 to move upward in the Z direction, which will compress the first elastic component 24 and the guide component 25 to move upward in the Z direction. This will drive the first cutting component 12 and the second cutting component 13 to move in opposite directions in the X direction, thereby cutting the welding strip. After the welding strip is cut, the driving component 21 drives the second mounting component 22 to move downward in the Z direction, which will drive the guide component 25 to move downward in the Z direction. The first cutting component 12 and the second cutting component 13 will move in opposite directions in the X direction, thereby returning to the original position. The driving component 21 continues to drive the second mounting component 22 to move downward in the Z direction, which will drive the third mounting component 23 to move downward in the Z direction, thereby resetting the cutting mechanism 1.

[0052] The cutting device 100 in this embodiment can realize the movement of the cutting mechanism 1 along the Z direction through the driving mechanism 2, and drive the first cutting component 12 and the second cutting component 13 to move in opposite directions to cut the welding strip; it can realize the continuous operation of the cutting device 100 to reduce the working cycle and improve the working efficiency, and also make the structure of the cutting device 100 more compact and reduce the space occupied by the cutting device 100.

[0053] The first elastic component 24 can be a helical spring.

[0054] In one optional embodiment, the first cutter assembly 12 has a first groove 1231, and the second cutter assembly 13 has a second groove 1331. The first groove 1231 is an inclined groove, and the second groove 1331 is an inclined groove. The guide assembly 25 includes a first mounting part 251, a first bearing 252, and a second bearing 253. The first mounting part 251 is disposed on the second mounting assembly 22. The first bearing 252 and the second bearing 253 are spaced apart in the first mounting part 251 along the X direction. The first bearing 252 is slidably connected to the first groove 1231, and the second bearing 253 is slidably connected to the second groove 1331. Specifically, when the first bearing 252 moves along the first groove 1231, the second bearing 253 moves along the second groove 1331, thereby driving the first cutter assembly 12 and the second cutter assembly 13 to move towards or away from each other.

[0055] In one specific embodiment, such as Figure 1 , Figure 2 and Figure 8 As shown, the first slide groove 1231 and the second slide groove 1331 are spaced apart along the X direction. The distance between the ends of the first slide groove 1231 and the second slide groove 1331 near the drive mechanism 2 in the X direction is a first distance L, and the distance between the ends of the first slide groove 1231 and the second slide groove 1331 away from the drive mechanism 2 in the X direction is a second distance H. The first distance L is greater than the second distance H. The first mounting part 251 is disposed on the side of the second mounting assembly 22 near the third mounting assembly 23. The first bearing 252 is disposed on the first mounting part 251, and the axial direction of the first bearing 252 is the same as the Y direction. The second bearing 253 is disposed on the first mounting part 251, and the axial direction of the second bearing 253 is the same as the Y direction. The first bearing 252 and the second bearing 253 are spaced apart along the X direction. The first bearing 252 is slidably connected to the first slide groove 1231, and the second bearing 253 is slidably connected to the second slide groove 1331. When the guide assembly 25 moves upward in the Z direction, the first bearing 252 moves relative to the first slide groove 1231 from the end near the drive mechanism 2 to the end away from the drive mechanism 2, and the second bearing 253 moves relative to the second slide groove 1331 from the end near the drive mechanism 2 to the end away from the drive mechanism 2. The first cutter assembly 12 and the second cutter assembly 13 will move in opposite directions in the X direction, thereby cutting the welding strip. In this embodiment, by sliding the bearings and slide grooves, the Z-direction movement of the first cutter assembly 12 and the second cutter assembly 13 can be changed to the X-direction movement, thereby cutting the welding strip. The structure is simple and easy to install.

[0056] In another specific embodiment, the first slide groove 1231 and the second slide groove 1331 are spaced apart along the X direction. The distance between the ends of the first slide groove 1231 and the second slide groove 1331 near the drive mechanism 2 in the X direction is a first distance L, and the distance between the ends of the first slide groove 1231 and the second slide groove 1331 away from the drive mechanism 2 in the X direction is a second distance H. The first distance L is smaller than the second distance H.

[0057] To further explain, the first cutter assembly 12 and the second cutter assembly 13 move simultaneously, that is, the first cutter assembly 12 and the second cutter assembly 13 move towards the middle position of the solder strip at the same time, so that the solder strip will not bend during the cutting process.

[0058] In one alternative implementation, such as Figure 1 and Figure 3 As shown, the second mounting component 22 and the third mounting component 23 are arranged at intervals along the Z direction; the drive mechanism 2 also includes a first adjustment component 27, which is used to adjust the distance between the second mounting component 22 and the third mounting component 23 in the Z direction; specifically, since the second mounting component 22 and the third mounting component 23 are connected by a first elastic component 24, the preload of the first elastic component 24 can be adjusted by adjusting the distance between the second mounting component 22 and the third mounting component 23 through the first adjustment component 27.

[0059] In one alternative embodiment, the first adjustment component 27 includes a screw threadedly connected to the second mounting component 22 and the third mounting component 23 along the Z direction. The distance between the second mounting component 22 and the third mounting component 23 can be adjusted by adjusting the size of the screw screw screwed into the third mounting component 23.

[0060] In another alternative implementation, such as Figure 1 , Figure 3 and Figure 4 As shown, the second mounting component 22 and the third mounting component 23 are arranged at intervals along the Y direction; as Figure 1As shown, the second mounting assembly 22 and the third mounting assembly 23 are arranged at intervals in the Y direction; specifically, the cutting device 100 also includes a mounting mechanism 3, which includes a first mounting plate 31. The second mounting assembly 22 is mounted on the first mounting plate 31 via a first sliding assembly 34, and the second mounting assembly 22 can move relative to the first mounting plate 31 in the Z direction via the first sliding assembly 34. The third mounting assembly 23 is mounted on the first mounting plate 31 via a second sliding assembly 35, and the second mounting assembly 22 can move relative to the first mounting plate 31 in the Z direction via the second sliding assembly 35. The height of the sliding component 34 in the Y direction is greater than that of the second sliding component 35 in the Y direction, so the second mounting component 22 and the third mounting component 23 can be arranged at intervals in the Y direction. Since the first mounting component 11 of the cutting mechanism 1 is mounted on the third mounting component 23, and the first cutting component 12 and the second cutting component 13 are connected to the guide component 25 mounted on the second mounting component 22, the second mounting component 22 and the third mounting component 23 are arranged at intervals in the Y direction, which facilitates the connection between the guide component 25 on the second mounting component 22 and the first cutting component 12 and the second cutting component 13.

[0061] Further explanation: The first adjustment assembly 27 includes a second mounting portion 271 and a first adjustment rod 272. The second mounting portion 271 includes a first mounting block 2711 and a second mounting block 2712. The first mounting block 2711 is connected to the second mounting block 2712, and the second mounting block 2712 is located on the side of the second mounting assembly 22 away from the third mounting assembly 23. The first adjustment rod 272 is connected to the second mounting block 2712 and abuts against the second mounting assembly 22. Since the second mounting assembly 22 and the third mounting assembly 23 are arranged at intervals in the Z and Y directions, the first mounting block 2711 is located in the Y direction on the second mounting assembly 2712. Between the second and third mounting components 22, the second mounting block 2712 is located on the side of the second mounting component 22 away from the third mounting component 23 in the Z direction, and the second mounting block 2712 protrudes or is flush with the second mounting component 22 in the Y direction; the first mounting block 2711 is connected to the second mounting block 2712, and the first adjusting rod 272 is threadedly connected to the second mounting block 2712. The first adjusting rod 272 can abut against the second mounting component 22. By adjusting the size between the first adjusting rod 272 and the second mounting component 22, the distance between the second mounting component 22 and the third mounting component 23 can be adjusted to adjust the preload of the first elastic component 24.

[0062] To further explain, on the one hand, by adjusting the preload of the first elastic component 24, the position of the first bearing 252 in the first slide groove 1231 and the position of the second bearing 253 in the second slide groove 1331 are adjusted. Specifically, when the first cutter assembly 12 and the second cutter assembly 13 are first adjusted and then aligned, the first bearing 252 is placed in the first slide groove 1231 and the second bearing 253 is placed in the second slide groove 1331. The positions of the second mounting component 22 and the third mounting component 23 will then change. The positions of the first bearing 252 in the first slide groove 1231 and the second bearing 253 in the second slide groove 1331 will also change. Therefore, by adjusting the distance between the second mounting component 22 and the third mounting component 23, the first bearing 252 in the first slide groove 1231 and the second bearing 253 in the second slide groove 1331 can be adjusted to a suitable position. On the other hand, the elastic force of the first elastic component 24 is also the driving force supporting the movement of the third mounting component 23. By adjusting the preload of the first elastic component 24, the first elastic component 24 can support the third mounting component 23.

[0063] like Figure 1 and Figure 3 As shown, in an optional embodiment, the cutting device 100 further includes a mounting mechanism 3, the third mounting component 23 is slidably connected to the mounting mechanism 3, and the second mounting component 22 is slidably connected to the mounting mechanism 3; the mounting mechanism 3 provides support for the third mounting component 23 and the second mounting component 22.

[0064] The driving mechanism 2 further includes a limiting component 26, which is disposed on the mounting mechanism 3. The limiting component 26 is located on the side of the third mounting component 23 away from the second mounting component 22, and the third mounting component 23 can abut against the limiting component 26. Specifically, the limiting component 26 is disposed on the mounting mechanism 3, and the limiting component 26 is located on the side of the third mounting component 23 away from the second mounting component 22. It can be understood that the limiting component 26 is located above the third mounting component 23 in the Z direction. When the driving component 21 drives the second mounting component 22 to move upward in the Z direction, the third mounting component 23 will abut against the limiting component 26. When the third mounting component 23 abuts against the limiting component 26, the third mounting component 23 will no longer move in the Z direction. The driving component 21 continues to drive the second mounting component 22 to move in the Z direction, and the second mounting component 22 will compress the first elastic component 24, thereby driving the first cutter component 12 and the second cutter component 13 to move in the X direction through the guide component 25 disposed on the second mounting component 22.

[0065] In one specific embodiment, such as Figure 3As shown, the mounting mechanism 3 also includes a first side plate 32 and a second side plate 33. The first side plate 32 and the second side plate 33 are spaced apart on the first mounting plate 31 along the X direction, or the first side plate 32 and the second side plate 33 are spaced apart along the X direction. The first side plate 32 and the first mounting plate 31 are not connected. The second side plate 33 and the first mounting plate 31 are not connected. The second mounting component 22 and the third mounting component 23 are both located between the first side plate 32 and the second side plate 33. The limiting component 26 includes a first limiting part 261 and a second limiting part 262. The first limiting part 261 is located on the first side plate 32 and the second limiting part 262 is located on the second side plate 33. The third mounting component 23 can abut against the first limiting part 261 and the second limiting part 262 on both sides in the X direction, thereby limiting the movement distance of the third mounting component 23 in the Z direction.

[0066] In an optional embodiment, the limiting component 26 can adjust its relative position with the mounting mechanism 3; that is, the limiting component 26 can adjust its own position on the mounting mechanism 3, thereby adjusting the distance by which the third mounting component 23 moves upward in the Z direction, so as to adjust the moving distance of the cutting mechanism 1 in the Z direction according to actual needs.

[0067] In one specific embodiment, the limiting component 26 includes a limiting member and an adjusting member. The limiting member is adjustable on the mounting mechanism via the adjusting member, and the adjusting member can adjust the position of the limiting member. Specifically, the limiting member is disposed on the adjusting member, which is screwed into the mounting mechanism 3. By adjusting the size of the adjusting member screwed into the mounting mechanism 3, the distance between the limiting member 263 and the mounting mechanism 3 can be adjusted, thereby adjusting the distance the third mounting component 23 moves upward in the Z direction. Thus, the moving distance of the cutting mechanism 1 in the Z direction can be adjusted according to actual needs.

[0068] like Figure 10 As shown, in another specific embodiment, the limiting component 26 includes a threaded rod 263, a first nut 264, and a second nut 265. The mounting mechanism 3 has a mounting hole, and the threaded rod 263 is partially inserted into the mounting hole. The first nut 264 is located on the side of the mounting mechanism 3 away from the third mounting component 23 and is screwed onto the threaded rod 263. The second nut 265 is located on the side of the mounting mechanism 3 close to the third mounting component 23 and is screwed onto the threaded rod 263. The first nut 264 and the second nut 265 can prevent the threaded rod 263 from disengaging from the mounting hole. By adjusting the position of the first nut 264 and the second nut 265 on the threaded rod 263, the position between the threaded rod 263 and the mounting mechanism 3 can be adjusted, thereby adjusting the distance by which the third mounting component 23 moves upward in the Z direction. Thus, the movement distance of the cutting mechanism 1 in the Z direction can be adjusted according to actual needs.

[0069] In one particular implementation, the drive assembly 21 is a linear motor 211, a cylinder, or a hydraulic cylinder.

[0070] like Figure 3 As shown, in another specific embodiment, the drive assembly 21 includes a motor 211, a drive wheel 212, a driven wheel 213, a conveyor belt 214, a lead screw 215, and a nut seat 216. The drive wheel 212 is connected to the output end of the motor 211. The driven wheel 213 is spaced apart from the drive wheel 212. The conveyor belt 214 is fitted over the driven wheel 213 and the drive wheel 212. The lead screw 215 is connected to the driven wheel 213. The nut seat 216 is rotatably connected to the lead screw 215. The motor 211 and the lead screw 215 are spaced apart along the X direction. The second mounting assembly 22 is connected to the nut seat 216. The axis of the lead screw 215 is the same as that in the Z direction. Specifically, the axes of the output end of the motor 211, the drive wheel 212, and the lead screw 215 are aligned. The axis of the driven wheel 213 is the same as the axis in the Z direction. The nut seat 216 is rotatably connected to the lead screw 215, and the second mounting assembly 22 is connected to the nut seat 216. Therefore, when the lead screw 215 is driven to rotate around its own axis by the motor 211, the nut seat 216 will move in the Z direction, thus driving the second mounting assembly 22 to move in the Z direction. In this embodiment, the lead screw 215 and the motor 211 are arranged at intervals in the X direction. The lead screw 215 and the motor 211 are connected by the driving wheel 212, the driven wheel 213 and the conveyor belt 214. The nut seat 216 is rotatably connected to the lead screw 215 and is connected to the second mounting assembly 22. While driving the second mounting assembly 22 to move in the Z direction, the drive assembly 21 can be reasonably arranged so that the structure of the drive mechanism 2 is more reasonable and compact.

[0071] The nut seat 216 can be a single component; or, the nut seat 216 can include a first component and a second component. The first component is rotatably connected to the lead screw 215, and the second component is connected to the first component. The second component has a light hole through which the lead screw 215 passes. The second component is connected to the second mounting assembly 22. The motor 211 drives the lead screw 215 to rotate around its own axis. The first component moves relative to the lead screw 215 in the Z direction to drive the second component to move in the Z direction, thereby driving the second mounting assembly 22 to move in the Z direction.

[0072] In one alternative implementation, such as Figures 5-9As shown, the first mounting assembly 11 further includes a first mounting base 111 and a second mounting base 112. The first mounting base 111 and the second mounting base 112 are disposed opposite each other along the Y direction. The first mounting base 111 and the second mounting base 112 are connected by a connecting assembly 113. The first cutter assembly 12 is slidably connected to the first mounting base 111 along the X direction, and the second cutter assembly 13 is slidably connected to the second mounting base 112 along the X direction. Specifically, the first mounting base 111 and the second mounting base 112 are arranged opposite to each other along the Y direction. The first mounting base 111 and the second mounting base 112 are connected by a connecting component 113, which can restrict the movement of the first mounting base 111 and the second mounting base 112 in the X and Z directions. The first cutting component 12 is located on the side of the first mounting base 111 close to the second mounting base 112 and can slide relative to the first mounting base 111 in the X direction. The second cutting component 13 is located on the side of the second mounting base 112 away from the first mounting base 111 and can slide relative to the second mounting base 112 in the X direction. In this embodiment, the first mounting base 111 and the second mounting base 112 can move relative to each other in the Y direction, thereby avoiding the distance between the first cutting component 12 and the second cutting component 13 in the Y direction being too large or too small.

[0073] The first mounting base 111 or the second mounting base 112 of the cutting mechanism 1 is disposed on the third mounting assembly 23. Preferably, the second mounting base 112 of the cutting mechanism 1 is disposed on the third mounting assembly 23. Specifically, the third mounting assembly 23 is provided with a first fixing base 231 and a second fixing base 232, which are spaced apart along the X direction. Both the first fixing base 231 and the second fixing base 232 are provided with a first connecting hole. The first mounting base 112 is provided with a plurality of second connecting holes 1122, which correspond to the first connecting holes. The cutting mechanism 1 is mounted on the third mounting assembly 23 by screwing screws into the first connecting holes and the second connecting holes 1122.

[0074] like Figure 7As shown, in an optional embodiment, the first mounting base 111 has a first through hole 1111 and a second through hole 1112, and a platform 1113 is formed between the first through hole 1111 and the second through hole 1112. The second through hole 1112 is closer to the second mounting base 112 than the first through hole 1111. The second mounting base 112 has a third through hole 1121. The axes of the first through hole 1111, the second through hole 1112, and the third through hole 1121 coincide. The inner diameter of the first through hole 1111 is larger than the inner diameter of the second through hole 1112, and the inner diameter of the second through hole 1112 is larger than the inner diameter of the third through hole 1121. The first through hole 1111, the second through hole 1112, and the third through hole 1121 are arranged concentrically.

[0075] The cutting mechanism 1 further includes a second adjusting component 14, which includes a second adjusting rod 142 and a second elastic component. The second adjusting rod 142 includes a first part 1421, a second part 1422, and a third part 1423 connected in sequence. The outer diameter of the first part 1421 is smaller than the outer diameter of the second part 1422, the outer diameter of the second part 1422 is smaller than the outer diameter of the third part 1423, and the outer diameter of the second part 1422 is larger than the inner diameter of the third through hole 1121. The second elastic component... The component is fitted onto the second part 1422 and located in the first through hole 1111. One end of the second elastic component abuts against the platform 1113, and the other end of the second elastic component abuts against the third part 1423. The first part 1421 is threadedly connected to the third through hole 1121. Specifically, the first part 1421 is screwed into the third through hole 1121 and threadedly connected to it. Because the outer diameter of the second part 1422 is larger than the inner diameter of the third through hole 1121, the second part 1422 will not be screwed into the third through hole 1121. Inside the through hole 1121, the end face of the second part 1422 near the first part 1421 abuts against the first mounting base 111 or the platform 1113. The second elastic component is sleeved on the second part 1422, that is, the second elastic component is located inside the first through hole 1111. One end of the second elastic component abuts against the platform 1113, and the other end of the second elastic component abuts against the third part 1423. The third part 1423 will press the second elastic component towards the second mounting base 112. Through the elastic force of the second elastic component, it will cause... The first cutting blade assembly 12, located on the first mounting base 111, moves closer to and adheres to the second cutting blade assembly 13, located on the second mounting base 112, to prevent relative movement between the first cutting blade assembly 12 and the second cutting blade assembly 13 in the Y direction. In other words, the first cutting blade assembly 12 and the second cutting blade assembly 13 are tightly adhered to each other under the elastic force of the second elastic component, ensuring relative sliding between them in the X direction while preventing relative movement in the Y direction. In this embodiment, different second elastic components can be replaced as needed, eliminating the tedious adjustment process of the gap between the first cutting blade assembly 12 and the second cutting blade assembly 13, thereby improving assembly and adjustment efficiency.

[0076] In one specific embodiment, the second elastic component includes only the elastic element 141, which can be a helical spring. In this embodiment, the second elastic component with different elastic coefficients can be replaced as needed, thereby eliminating the tedious adjustment process of the gap between the first cutter assembly 12 and the second cutter assembly 13, and thus improving the efficiency of assembly and adjustment.

[0077] In another specific embodiment, the second elastic component includes an adjusting shim 143 and an elastic element 141. The adjusting shim 143 abuts against the table surface 1113, one end of the elastic element 141 abuts against the adjusting shim 143, and the other end of the elastic element 141 abuts against the third part 1423. In this embodiment, when it is necessary to adjust the distance between the first cutter assembly 12 and the second cutter assembly 13, in addition to replacing the elastic element 141 with a different elastic coefficient, the adjusting shim 143 with a different thickness can also be replaced, thereby reducing the difficulty of adjustment and improving the adjustment efficiency.

[0078] Among them, the elastic element 141 is a helical spring.

[0079] In one alternative implementation, such as Figure 7 As shown, the first cutter assembly 12 includes a first blade 121 and a first connecting seat 122, the first blade 121 being disposed on the first connecting seat 122, and the first connecting seat 122 being slidably connected to the first mounting seat 111; the second cutter assembly 13 includes a second blade 131 and a second connecting seat 132, the second blade 131 being disposed on the second connecting seat 132, and the second connecting seat 132 being slidably connected to the second mounting seat 112;

[0080] like Figure 6 As shown, the first blade 121 is provided with a plurality of first cutting edges 1211, and a first cutting edge 1212 is formed between two adjacent first cutting edges 1211. The second blade 131 is provided with a plurality of second cutting edges 1311 that correspond one-to-one with the first cutting edges 1211, and a second cutting edge 1312 is formed between two adjacent second cutting edges 1311. Specifically, multiple first cutting edges 1211 are spaced apart along the X direction, with a first cutting edge 1212 formed between two adjacent first cutting edges 1211. Multiple second cutting edges 1311 are spaced apart along the X direction, with a second cutting edge 1312 formed between two adjacent second cutting edges 1311. One first cutting edge 1211 and one second cutting edge 1311 are arranged opposite to each other in the Y direction. Each welding strip passes through the corresponding first cutting edge 1211 and second cutting edge 1311. The first and second cutting edges move in opposite directions along the X direction. Adjacent first cutting edges 1212 and second cutting edges 1312 move simultaneously toward the welding strip, thereby cutting the welding strip. Since there are multiple first cutting edges 1211 and multiple second cutting edges 1311, multiple welding strips can be cut simultaneously.

[0081] Furthermore, the simultaneous movement of the first blade 131 and the second blade 132, without affecting the working efficiency of the cutting device 100, increases the size of the first cutting edge 1211 (which can be understood as the distance between two adjacent first blades 1212) and the size of the second cutting edge 1311 (the distance between two adjacent second blades 1312). This facilitates the passage of the solder ribbon, reduces the probability of the solder ribbon rubbing against the first blade 1212 and the second blade 1312, and also reduces the amount of flux residue on the first blade 121 and the second blade 131, preventing contamination and corrosion of the first blade 121 and the second blade 131, thereby extending the service life of the cutting mechanism 1.

[0082] In an optional embodiment, the first cutter assembly 12 further includes a first sliding portion 123, a first groove 1231 disposed on the first sliding portion 123, and the first sliding portion 123 disposed on the side of the first connecting seat 122 away from the first blade 121; the second cutter assembly 13 further includes a second sliding portion 133, a second groove 1331 disposed on the second sliding portion 133, and the second sliding portion 133 disposed on the side of the second connecting seat 132 away from the second blade 131.

[0083] In an optional embodiment, the first cutter assembly 12 further includes a receiving groove 124, which is disposed on the first connecting seat 122 and is spaced apart from the first blade 121 in the same direction. Since flux adheres to the solder strip, the receiving groove 124 is used to receive flux dripping from the solder strip to prevent flux from seeping into the cutting device 100.

[0084] In one alternative implementation, such as Figure 1 and Figure 3 As shown, the guide mechanism 4 includes a guide rail 41, a slider 43, and a guide rail clamp 42. The slider 43 is mounted on the mounting mechanism 3 and is slidably connected to the guide rail 41. The mounting mechanism 3 can move relative to the guide rail 41 in the Y direction via the slider 43. The guide rail clamp 42 is mounted on the guide rail 41 and can lock the mounting mechanism 3 at any position on the guide rail 41 to prevent the drive mechanism 2 and the cutter mechanism 1 mounted on the mounting mechanism 3 from moving in the Y direction during operation.

[0085] According to a second aspect of the embodiments of this application, a string welding machine is provided, including the cutting device 100 described above.

Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of this application.
