[0062] In the strip processing process, to improve material utilization, two discarded strips are usually welded together to form a continuous strip for reuse. This not only reduces material waste but also improves production efficiency and cost-effectiveness.

[0063] In existing technologies, strip welding devices typically include a shearing mechanism and a welding mechanism on the machine base. First, the shearing mechanism simultaneously cuts two strips, removing irregular end faces to ensure consistency in the cut surfaces of the two strips. After shearing, the welding mechanism moves to the strips to perform welding, thus completing the welding of the two strips.

[0064] However, the welding quality of existing strip welding devices is unstable, which easily leads to low production efficiency.

[0065] This utility model proposes a strip welding equipment 100, which aims to solve the problems of unstable welding quality and low production efficiency.

[0066] Please see Figures 1 to 6In one embodiment of this utility model, a strip welding device 100 is used for strip welding. One end of the strip forms a connected welding section and a shearing section. The strip welding device 100 includes: a machine base 1, a shearing and pressing mechanism 2, and a welding and pressing mechanism 3. The machine base 1 forms a shearing area 111 and a welding area 112. The shearing and pressing mechanism 2 includes a shearing component 21, a first positioning component 23, and a shearing and pressing component 22. The first positioning component 23 is disposed on the machine base 1 and is positioned corresponding to the shearing area 111. The first positioning component 23 has a first contact surface 2331. The shearing component 21 is disposed on the machine base 1 and includes a cutter module 210 disposed in the shearing area 111. The shearing and pressing component 22 is disposed on the machine base 1 and is adjacent to the shearing component 21. The welding and pressing mechanism 3 is disposed on the machine base 1 and corresponds to the welding area 112, and is used to weld the welding sections of the two strips in the welding area 112. The shearing section abuts against the first contact surface 2331 and is aligned, and the shearing pressing assembly 22 presses the material strip so that the shearing assembly 21 drives the cutter module 210 to move closer to or away from the shearing section for shearing the shearing section.

[0067] In this embodiment, please refer to Figures 1 to 3 The machine base 1 not only serves as the supporting structure for the strip welding equipment 100, but also includes a shearing area 111 and a welding area 112. The shearing area 111 cuts off the sheared segments to ensure the flatness of the end faces to be welded, while the welding area 112 welds the sheared strips together. The shearing and pressing mechanism 2 includes a shearing component 21, a first positioning component 23, and a shearing and pressing component 22. The first positioning component 23 provides a precise positioning reference for the strip through a first abutment surface 2331, enabling the sheared segments to align with the first abutment surface 2331. After the shearing and pressing component 22 presses the strip, the cutter module 210 approaches and cuts off the sheared segments, preparing for the subsequent welding process. The welding and pressing mechanism 3 then welds the two sheared strips together within the welding area 112. The two strips are positioned by contacting the first contact surface 2331, which ensures the consistency of the shearing surface, avoids the requirement to shear the two strips at the same time, improves the flexibility of operation and the precision of shearing, and thus ensures the welding quality and improves the production efficiency.

[0068] In one embodiment, the machine base 1 has a clearance hole 1111 located in the shearing area 111. The first positioning component 23 includes a positioning drive 231, a positioning base 232, and a positioning plate 233. The positioning drive 231 is disposed on the machine base 1 and adjacent to the clearance hole 1111. The positioning base 232 is connected to the output end of the positioning drive 231. The positioning plate 233 is disposed on the positioning base 232, and at least a portion of the positioning plate 233 is located within the clearance hole 1111. First abutment surfaces 2331 are formed on opposite sides of the positioning plate 233. The positioning drive 231 drives the positioning base 232 to move the positioning plate 233 within the clearance hole 1111, forming a first position and a second position relative to the cutter module 210, thus enabling the shearing and pressing mechanism 2 to have a positioning state and a shearing state. In the positioning state, the positioning plate 233 is located in the first position, and the shearing section is aligned with the first contact surface 2331, and the shearing pressing assembly 22 presses the material strip; in the shearing state, the positioning plate 233 is located in the second position, and the shearing assembly 21 drives the cutter module 210 to approach the shearing section to shear the shearing section.

[0069] This is understandable; please refer to [link / reference]. Figures 3 to 5 The positioning drive 231 drives the positioning base 232, causing the positioning plate 233 to move vertically within the clearance hole 1111 to form a first position and a second position. When the positioning plate 233 is in the first position, the shearing and pressing mechanism 2 is in a positioning state, with part of the positioning plate 233 protruding from the clearance hole 1111, allowing the shearing section to abut against one side of the positioning plate 233, i.e., against the first abutment surface 2331, thereby completing the positioning of the strip. When the positioning plate 233 is in the second position, the shearing and pressing mechanism 2 is in a shearing state, with the top of the positioning plate 233 located within the clearance hole 1111, thus preventing the positioning plate 233 from interfering with or colliding with the cutting module 210 during the shearing process.

[0070] In another embodiment, since the cutting surface of the cutter module 210 in contact with the material strip has a certain thickness, a groove is formed on the cutting surface. When the cutter module 210 moves relative to the positioning plate 233, the positioning plate 233 can enter the groove, thereby avoiding interference between the two. At this time, the positioning plate 233 does not need to move.

[0071] In this embodiment, the positioning plate 233 has an inverted T-shaped cross-section. The horizontal plane of the positioning plate 233 is fixed to the positioning base 232, and the opposite sides of the vertical plane of the positioning plate 233 form a first abutment surface 2331. Of course, the cross-section of the positioning plate 233 can also be L-shaped, I-shaped, or other shapes.

[0072] In one embodiment, the machine base 1 is provided with a through hole 116 near the clearance hole 1111, and a linear bearing 235 is provided in the through hole 116. The first positioning component 23 also includes a first guide post 234 provided on the positioning base 232, and the first guide post 234 is movably inserted through the linear bearing 235.

[0073] In this embodiment, please refer to Figure 4 and Figure 5 Along the extension direction of the clearance hole 1111, two through holes 116 are formed at intervals on both sides of the clearance hole 1111. A linear bearing 235 is installed in each of the two through holes 116. The output end of the positioning drive member 231 passes through a linear bearing 235 and is connected to one end of the positioning base 232. A first guide post 234 passes through the other linear bearing 235 and is connected to the other end of the positioning base 232. The positioning drive member 231 drives the positioning base 232 to move the first guide post 234 in the vertical direction.

[0074] Understandably, the positioning base 232 and the positioning drive 231 are located opposite each other on the machine tool 1. To avoid interference between the positioning drive 231 and the movement of the cutter module 210, the connection between the positioning drive 231 and the positioning base 232 is located at one end of the positioning base 232, and the output end of the positioning drive 231 passes through the through hole 116 via a linear bearing 235, thereby allowing the positioning base 232 to move vertically relative to the machine tool 1 under the drive of the positioning drive 231. Correspondingly, a first guide post 234 is provided at the other end of the positioning base 232 to ensure the stability of the positioning base 232 during movement.

[0075] In another embodiment, the positioning base 232 and the positioning drive 231 can be simultaneously located below the machine base 1. In this case, no matter where the connection between the positioning drive 231 and the positioning base 232 is located on the positioning base 232, the positioning drive 231 will not interfere with the movement of the cutter module 210.

[0076] In one embodiment, the shearing region 111 forms a receiving cavity 115, and a clearance hole 1111 is formed in the bottom wall of the receiving cavity 115. The shearing assembly 21 also includes a shearing drive 211, which is disposed on the machine base 1 and corresponding to the shearing region 111. The cutter module 210 includes an upper cutter and a lower cutter. The upper cutter 212 is disposed at the output end of the shearing drive 211. The lower cutter 213 is disposed in the receiving cavity 115, and the lower cutter 213 is disposed opposite to the upper cutter 212. The lower cutter 213 has a clearance space 214, which communicates with the clearance hole 1111. In the shearing state, the shearing drive 211 drives the upper cutter 212 to approach the lower cutter 213 to shear the shearing segment.

[0077] In this embodiment, please refer to Figure 3 and Figure 4 There are two sets of lower cutters 213, which are respectively located on both sides of the receiving cavity 115. A clearance space 214 is formed between the two sets of lower cutters 213. When the upper cutter 212 moves relative to the lower cutter 213, part of the upper cutter 212 can enter the clearance space 214, thereby avoiding motion interference. The clearance hole 1111 is located in the receiving cavity 115 and between the two lower cutters 213. When the positioning plate 233 moves in the vertical direction, the positioning plate 233 can protrude out of the clearance hole 1111 and enter the clearance space 214.

[0078] Optionally, a guide groove 1151 is also formed on the side wall of the clearance space 214, and the upper cutter 212 can slide along the guide groove 1151, thereby improving the stability of the upper cutter 212 when moving relative to the lower cutter 213.

[0079] In another embodiment, there is only one set of lower cutters 213, and the lower cutters 213 are U-shaped. The lower cutters 213 are arranged to form a clearance space 214. The upper cutter 212 and the positioning plate 233 can both be inside the lower cutter 213 and move vertically relative to the lower cutter 213.

[0080] In another embodiment, both the upper cutter 212 and the lower cutter 213 are connected to the shearing drive 211. Driven by the shearing drive 211, the upper cutter 212 and the lower cutter 213 can move relative to each other simultaneously to shear the segment. Optionally, the upper cutter 212 and the lower cutter 213 form a scissor structure, and applying pressure to the same end of both causes the other end of both to shear the segment.

[0081] In one embodiment, the upper cutter 212 forms an inclined cutting surface on one side relative to the lower cutter 213. By providing an inclined cutting surface, it helps to reduce the resistance encountered during shearing, making the shearing smoother.

[0082] Alternatively, the cutting surface of the upper cutter 212 can also be set to a horizontal plane, but this setting will result in greater resistance.

[0083] In one embodiment, the shearing and pressing assembly 22 includes two sets, which are respectively disposed on opposite sides of the cutter module 210. Each set of shearing and pressing assembly 22 includes a shearing and pressing drive 221, a first connector 222, and multiple pressing blocks 223. The shearing and pressing drive 221 is disposed on the machine base 1. The first connector 222 is disposed at the output end of the shearing and pressing drive 221. The multiple pressing blocks 223 are connected to the first connector 222 and arranged along the extending direction of the first connector 222. The shearing and pressing drive 221 drives the first connector 222 to move the pressing blocks 223 to press the material strip in the shearing area 111.

[0084] Generally, to achieve the material pressing function, only one pressure plate is needed to press the strip. However, in the shearing and pressing mechanism 2, after pressing the strip, a shearing step is still required. During the shearing process, the strip is also subjected to horizontal shearing force. If a pressure plate is used for pressing, the pressure on the strip may not be sufficient, causing the strip to shift during the shearing process. This affects the consistency of the shearing surfaces of the two strips, and consequently affects the quality of the final welding.

[0085] To address the aforementioned issues, this embodiment may refer to... Figure 4 The shearing and pressing assembly 22 is provided with a plurality of pressing blocks 223, which are arranged along the extension direction of the first connector 222. Compared with the traditional single pressing plate pressing the entire shearing section, the use of multiple pressing blocks 223 reduces the contact area with the material strip, thereby generating greater pressure and improving the pressing effect when the output power is constant.

[0086] In one embodiment, the machine base 1 includes a base plate 11 and a mounting base 12 disposed on the base plate 11. The base plate 11 has a shearing area 111 and a welding area 112. The shearing and pressing assembly 22 is mounted on the mounting base 12. The output end of the shearing and pressing drive 221 is connected to the middle of the first connecting member 222. The two ends of the first connecting member 222 are provided with second guide posts 224, which are movably mounted on the mounting base 12. The shearing and pressing drive 221 drives the first connecting member 222 to move the second guide posts 224.

[0087] In this embodiment, please refer to Figure 1 and Figure 2 The machine base 1 is also equipped with a mounting base 12, which is used for mounting the shearing and pressing mechanism 2 and the welding pressing structure. This allows the shearing and pressing mechanism 2 and the welding pressing structure to be set parallel to each other on the machine base 1, making the strip welding equipment 100 more aesthetically pleasing and saving space. The mounting base 12 not only strengthens the structural strength during installation and ensures the coordinated operation of various components, but also facilitates disassembly and maintenance.

[0088] This is understandable; please refer to [link / reference]. Figure 4 In order to improve the stability of the shearing and pressing assembly 22 when it moves, the output end of the shearing and pressing drive 221 is connected to the middle of the first connector 222. The two ends of the first connector 222 are provided with second guide posts 224, and the second guide posts 224 are mounted on the mounting base 12 through linear bearings 235.

[0089] In one embodiment, the welding area 112 is provided with a welding cavity 1122, and the bottom wall of the welding cavity 1122 is provided with a positioning hole 1121. The welding pressing mechanism 3 includes a welding assembly 31, a second positioning assembly 33, and a welding pressing assembly 32. The welding assembly 31 is disposed on the machine base 1 and is disposed corresponding to the welding area 112. The welding pressing assembly 32 is disposed on the machine base 1 and is disposed adjacent to the welding assembly 31. The second positioning assembly 33 is disposed on the machine base 1 and has two opposing second abutment surfaces 331. The second positioning assembly 33 drives the two second abutment surfaces 331 to pass through the positioning hole 1121 and enter the welding cavity 1122 to form a third position and a fourth position relative to the welding assembly 31, so that the welding pressing mechanism 3 has an aligned state and a welding state. In the alignment state, the two second abutment surfaces 331 are located in the third position, and the welding sections of the two strips are respectively abutted and aligned with the two second abutment surfaces 331; in the welding state, the two second abutment surfaces 331 are located in the fourth position, and the welding assembly 31 moves along the extension direction of the positioning hole 1121 to weld the two strips.

[0090] This is understandable; please refer to [link / reference]. Figure 3 and Figure 6 The welding pressing mechanism 3 positions the two strips using the second positioning component 33, the structure of which is similar to that of the first positioning component 23 and will not be described in detail here. After the two strips are positioned, the welding pressing component 32 presses the strips tightly onto the welding area 112, and finally the welding component 31 completes the welding.

[0091] In one embodiment, the welding assembly 31 includes a slide rail module 311 and a welding head 312. The slide rail module 311 is disposed on the machine base 1 and corresponds to the welding area 112. The welding head 312 is disposed at the output end of the slide rail module 311. The slide rail module 311 drives the welding head 312 to move along the extension direction of the positioning hole 1121.

[0092] This is understandable; please refer to [link / reference]. Figure 6 The sliding rail module 311 enables the welding head 312 to move along the extension direction of the welding area 112. The sliding rail module 311 can be a linear motor or a cylinder. In this embodiment, laser welding head 312 is used for welding.

[0093] In one embodiment, the welding clamping assembly 32 includes two sets, which are respectively disposed on opposite sides of the slide rail module 311. Each set of welding clamping assemblies 32 includes a welding clamping drive 321, a second connector 322, and a clamping plate 323. The welding clamping drive 321 is disposed on the machine base 1. The second connector 322 is disposed at the output end of the welding clamping drive 321. The clamping plate 323 is connected to the second connector 322. The welding clamping drive 321 drives the second connector 322 to move the clamping plate 323 to clamp the material strip in the welding area 112.

[0094] In this embodiment, please refer to Figure 3 and Figure 6 The welding pressing assembly 32 presses the strip tightly against the welding area 112. The structure of the welding pressing assembly 32 is similar to that of the shearing pressing assembly 22. However, since the strip is not subjected to horizontal shearing force at this time, a pressing plate 323 can be used for pressing.

[0095] Optionally, a plurality of pressing blocks 223 may be provided on the second connector 322 for pressing.

[0096] In one embodiment, a welding clamping drive 321 is mounted on a mounting base 12. The output end of the welding clamping drive 321 is connected to the middle of the second connector 322. The first connector 222 has third guide posts 324 at both ends, and the third guide posts 324 are movably mounted on the mounting base 12. The welding clamping drive 321 drives the second connector 322 to move the third guide posts 324 vertically.

[0097] Understandably, in order to improve the stability of the welding pressure assembly 32 when it moves, the output end of the welding pressure drive 321 is connected to the middle of the second connector 322. The two ends of the second connector 322 are provided with third guide posts 324, and the third guide posts 324 are mounted on the mounting base 12 through linear bearings 235.

[0098] In one embodiment, the machine base 1 is provided with a first strip stop 113, which corresponds to the shearing area 111 and is used to limit the side of the strip in the shearing area 111. Alternatively, the machine base 1 is provided with a second strip stop 114, which corresponds to the welding area 112 and is used to limit the side of the strip in the welding area 112.

[0099] In this embodiment, please refer to Figure 1 and Figure 2To ensure the strip enters the shearing zone 111 vertically, a first strip stop 113 is provided at the edge of the shearing zone 111, with the side of the strip abutting against the first strip stop 113. Furthermore, the first strip stop 113 ensures that the strip enters the shearing zone 111 at a consistent position each time. Through the cooperation of the first strip stop 113 and the first abutment surface 2331, the strip is positioned in a fixed position, ensuring the consistency of the shearing surfaces of the two strips. The second strip stop 114 has a similar structure to the first strip stop 113 and performs the same function, so it will not be described in detail here.

[0100] The working process of strip welding equipment 100 is as follows:

[0101] The first contact surface 2331 rises, and through the cooperation of the first strip stop 113 and the first contact surface 2331, a strip is positioned in the shearing area 111. The shearing and pressing assembly 22 presses the strip in the shearing area 111. The first contact surface 2331 falls, and the shearing assembly 21 cuts off the cut section of the strip. The shearing and pressing assembly 22 is then lifted, resulting in a cut strip. The second contact surface 331 rises, and through the cooperation of the second strip stop 114 and the second contact surface 331, the welding section of the strip is positioned on one side of the welding area 112. Then, another cut strip is obtained in the same way. Using the second strip stop 114 and the second contact surface 331, the second strip is positioned on the other side of the welding area 112. Finally, the second contact surface 331 falls, and the welding assembly 31 moves along the extension direction of the positioning hole 1121 to weld the two strips together. The welding and pressing assembly 32 is then lifted, resulting in a continuous strip.

[0102] The technical solution of this utility model positions the strip material through the first abutting surface 2331 of the first positioning component 23, and the shearing and pressing component 22 presses and fixes the strip material within the shearing area 111. The upper cutting blade 212 of the shearing component 21 moves closer to or further away from the shearing section to shear the shearing section. The two strip materials are positioned by abutting the first abutting surface 2331, which ensures the consistency of the shearing surface, thereby avoiding the requirement to shear the two strip materials at the same time, improving the flexibility of operation and the accuracy of shearing, and thus ensuring the welding quality.

[0103] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
