Description

Technical Field

[0001] This application belongs to the field of welding strip processing technology, specifically relating to a welding strip shearing mechanism and a welding strip fixing and shearing device. Background Technology

[0002] Segmented circular welding strips are produced using the latest segmented rolling process. They are high-efficiency segmented welding strips consisting of circular segments and flat segments. The circular segments are welded to the front of the solar cell, while the flat segments are welded to the back of the solar cell. This reduces the spacing between solar cells, thereby reducing the size of the module and saving material costs at the module end. Furthermore, using flat welding strips on the back of the solar cell reduces welding stress, minimizes microcracks at the edges of the solar cell during welding, and effectively reduces the occurrence of incomplete or misaligned welding on the back of the solar cell.

[0003] Before performing string welding on the welding strips, the entire welding strip needs to be cut to a suitable length for welding. In the existing technology, a single-blade cutter is usually used to cut multiple parallel welding strips as a whole. However, after long-term use, this cutting method inevitably results in some welding strips not being cut due to uneven wear on different parts of the cutter blade or cutter displacement, which affects the quality of the finished product.

[0004] Therefore, it is necessary to improve the existing technology to overcome the aforementioned defects. Utility Model Content

[0021] Furthermore, the positioning element has a plurality of evenly spaced positioning grooves, through which the welding strip passes;

[0038] Example 1:

[0039] Please see Figure 1 As shown, a welding strip shearing mechanism 6 includes a first shearing component 61, a second shearing component 63 that can connect with and cooperate with the first shearing component 61 to shear the welding strip, and a first drive plate 64 connecting the first shearing component 61 and the second shearing component 63. The first drive plate 64 can drive the first shearing component 61 and the second shearing component 63 to move alternately under the drive of an external force. In this embodiment, the alternate movement means that one side of the first shearing component 61 and the second shearing component 63 are always in contact with each other and move in opposite directions relative to the contact surfaces.

[0040] The first shearing component 61 has several evenly arranged first shearing openings 611, and a first blade 6111 is provided on one side of each first shearing opening 611. The second shearing component 63 has several evenly arranged second shearing openings 631, and a second blade 6311 is provided on one side of each second shearing opening 631. The first shearing openings 611 and the second shearing openings 631 are arranged in a one-to-one correspondence. The first blade 6111 and the second blade 6311 are located on opposite sides. When shearing the welding strip, the welding strip first passes through the corresponding first shearing opening 611 and the second shearing opening 631. Then, the first driving plate 64 drives the first shearing component 61 and the second shearing component 63 to move alternately, so that the welding strip can be sheared by the first blade 6111 and the second blade 6311 that move close to each other. This enables the simultaneous and individual shearing of multiple parallel welding strips, ensuring a good shearing effect for each welding strip and improving the quality of the finished product.

[0041] Specifically, the first shearing member 61 has a first connecting portion 612 at its end away from the first shearing opening 611, and a first groove 6121 is formed on the first connecting portion 612. The second shearing member 63 has a second connecting portion 632 at its end away from the second shearing opening 631, and a second groove 6321 is formed on the second connecting portion 632. Both the first groove 6121 and the second groove 6321 are inclined.

[0042] Furthermore, a first roller 641 and a second roller 642 are correspondingly provided on the first drive plate 64, which can be placed in the first slot 6121 and the second slot 6321. In this embodiment, the first slot 6121 and the second slot 6321 are inclined from top to bottom in a direction from being far apart to being close to each other. When the first drive plate 64 is driven to rise or fall by an external force, the first roller 641 and the second roller 642 can slide in the first slot 6121 and the second slot 6321 respectively, so as to drive the first shearing component 61 and the second shearing component 63 to move alternately, thereby driving the first blade 6111 and the second blade 6311 to move from being far apart to being close to each other or far apart, so as to cut the welding strip and place the welding strip.

[0043] In this embodiment, the first shearing component 61 and the second shearing component 63 are actually two identical components, which are assembled in reverse order during docking, thereby reducing the number of components and facilitating later maintenance and replacement.

[0044] The first shearing component 61 and the second shearing component 63 are respectively provided with a first through hole 613 and a second through hole 633 on both sides. The welding strip shearing mechanism 6 also includes a fixing member 8 passing through the first through hole 613 and the second through hole 633. The first shearing component 61 and the second shearing component 63 are connected to the external connecting seat by the fixing member 8. The length of the first through hole 613 and the second through hole 633 is greater than the diameter of the fixing member 8, so that the fixing member 8 can move within the first through hole 613 and the second through hole 633, ensuring that the first shearing component 61 and the second shearing component 63 can move alternately to achieve shearing.

[0045] Example 2:

[0046] Please see Figures 2 to 6As shown, a welding strip fixing and cutting device includes a connecting base 11 suitable for connection with an external machine body, a clamping assembly 1 disposed on the connecting base 11, positioning assemblies 2 disposed on both sides of the clamping assembly 1, and a welding strip cutting mechanism 66 disposed next to the clamping assembly 1. The clamping assembly 1 includes clamping parts 12 disposed on the connecting base 11. The welding strip to be cut is first positioned by the positioning assembly 2 and then clamped and fixed by the clamping parts 12. Then, the welding strip cutting mechanism 66 completes the cutting, thereby ensuring that all parts of the welding strip except the cut are fixed by the clamping assembly 1 during cutting, preventing twisting and deformation of the welding strip during the cutting process, and ensuring the quality of the finished product. The welding strip cutting mechanism 6 is the same as the welding strip cutting mechanism 6 described in Embodiment 1.

[0047] The welding strip fixing and shearing device also includes a first driving component 62 connected to the welding strip shearing mechanism 6. The driving end of the first driving component 62 extends to drive the driving plate 64 to move towards or away from the first shearing component 61 and the second shearing component 63. In this embodiment, the first driving component 62 is a cylinder.

[0048] It is worth noting that in this embodiment, two sets of clamping components 1 are provided, and the welding strip cutting mechanism 6 is disposed between the two sets of clamping components 1, thereby strengthening the fixing effect through the clamping action of the two sets of clamping components 1. In other embodiments, the number of clamping components 1 can be selected according to the actual situation, as long as it meets the actual needs, and no specific limitation is made here.

[0049] As described above, the connecting seat 11 extends to both sides to form an extension portion 111, and the positioning component 2 is installed on the extension portion 111. The positioning component 2 includes a positioning element 21 connected to the extension portion 111. Each set of positioning components 2 includes two parallel positioning elements 21, thereby further enhancing the positioning and fixing effect.

[0050] In other embodiments, the number of positioning elements 21 on each group of positioning components 2 can be selected according to the actual situation, such as one or more, as long as the actual needs can be met, and no specific limitation is made here.

[0051] The positioning component 21 has a number of evenly spaced positioning grooves 211. When positioning the welding strip, the welding strip passes through the positioning grooves 211. In this embodiment, the corresponding positioning grooves 211 on the two sets of positioning components 2 are on the same extension line, so that a welding strip passes through the positioning grooves 211 on four positioning components 21 at the same time to ensure positioning accuracy.

[0052] The connecting seat 11 has a mounting cavity 112, and the clamping component 12 is installed in the mounting cavity 112, with at least a portion of the clamping component 12 protruding outside the mounting cavity 112 to clamp the welding strip. The clamping component 12 includes a first gripper 121, a second gripper 122, and an elastic element 123 disposed between the first gripper 121 and the second gripper 122. A shaft 113 is disposed within the mounting cavity 112, and the first gripper 121 and the second gripper 122 are mounted on opposite sides of the shaft 113. Under external force, they can rotate relative to the shaft 113, compressing the elastic element 123 to store energy, thereby releasing the welding strip using the clamping component 12. After the external force disappears, the first gripper 121 and the second gripper 122 rotate again relative to the shaft 113 under the elastic action of the elastic element 123, thus clamping the welding strip using the clamping component 12. In this embodiment, the elastic element 123 is a spring.

[0053] Specifically, the clamping component 12 also includes a second drive plate 124 for driving the first gripper 121 and the second gripper 122 to rotate. A drive groove 1241 is formed on the second drive plate 124. One end of the first gripper 121 and the second gripper 122 connected to the elastic member 123 is placed in the drive groove 1241. The diameter of the drive groove 1241 gradually decreases from the opening inward. Under the drive of external force, the second drive plate 124 can move towards and away from the clamping component 12, thereby driving the first gripper 121 and the second gripper 122 to rotate relative to the shaft 113, thereby realizing the drive of the clamping component 12 to open or clamp the welding strip.

[0054] To drive the second drive plate 124, the welding strip fixing and shearing device further includes a second drive component 3 disposed on the connecting seat 11. The drive end 31 of the second drive component 3 is connected to the second drive plate 124. The extension and retraction of the drive end 31 can drive the second drive plate 124 to move towards or away from the clamping component 12, thereby realizing the drive operation. In this embodiment, the second drive component 3 is a cylinder. In other embodiments, corresponding drive components, such as electric cylinders, oil cylinders, or hydraulic cylinders, can be selected according to actual conditions, as long as they can meet the actual needs. No specific limitation is made here.

[0055] It is worth noting that a guide post 4 is provided at the end of the second drive plate 124 away from the clamping component 12, and a guide hole 5 is provided on the connecting seat 11. The guide post 4 and the guide hole 5 cooperate to guide, so that the driving process of the second drive plate 124 is more stable.

[0056] In summary, the welding strip cutting mechanism and welding strip fixing and cutting device of this utility model comprises a first cutting component, a second cutting component that engages with the first cutting component to cut the welding strip, and a drive plate connecting the first and second cutting components. The drive plate can drive the first and second cutting components to move alternately under external force. The first cutting component has several evenly arranged first cutting openings, and a first cutting edge is provided on one side of each first cutting opening. The second cutting component has several evenly arranged second cutting openings, and a second cutting edge is provided on one side of each second cutting opening. The first and second cutting openings are arranged in a one-to-one correspondence, and the first and second cutting edges are located on opposite sides. The welding strip passes through the corresponding first and second cutting openings to be cut by the first and second cutting edges, thereby enabling the simultaneous and individual cutting of multiple parallel welding strips, ensuring good cutting effect for each welding strip, and improving the quality of the finished product.

[0057] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, those skilled in the art can make other variations or modifications without creative effort, and all such variations or modifications should fall within the protection scope of this utility model.
