Description

Technical Field

[0001] This utility model relates to the field of laser welding equipment technology, specifically to a laser cutting and welding integrated machine. Background Technology

[0002] In modern continuous manufacturing industries such as consumer electronics, lithium batteries, and photovoltaic modules, a continuous supply of metal strip is crucial for ensuring the efficient operation of production lines. In the current production process, when a roll of strip is about to run out and a new reel needs to be replaced, the tail of the old strip needs to be cut, aligned, and welded to the head of the new strip.

[0003] However, existing cutting and welding equipment uses a blade shearing method to cut the strip, which causes mechanical damage to the strip during the cutting process, resulting in burrs on the cut end face, affecting the welding effect and the strength of the strip. At the same time, the blade will wear out during use and needs to be replaced regularly. When replacing the blade, the entire machine needs to be shut down and waiting, which will affect continuous production.

[0004] In addition, there may be micro-protrusions in the weld area after laser welding, which may pose a risk of jamming the flow channel fixture or scratching the material strip during high-speed winding and transmission. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, this utility model provides a laser cutting and welding integrated machine that integrates multiple processes such as feeding, positioning, clamping, cutting, welding, and weld leveling on the same equipment, realizing automated continuous production and greatly improving production efficiency. At the same time, it can avoid frequent machine stops for blade replacement due to wear of traditional cutters, ensuring the continuity of production. Moreover, the end face of the laser-cut strip is flat and burr-free, improving welding quality and strip strength. Finally, by setting up a weld leveling mechanism, the flatness of the welded product can be guaranteed, avoiding the risk of jamming the flow channel fixture or scratching the strip during high-speed winding and transmission.

[0040] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.

[0041] Reference Figure 1 This utility model provides a laser cutting and welding integrated machine, which includes a frame 1, a conveying mechanism 2, a pressing mechanism, a cutting and welding mechanism 4, and a weld leveling mechanism 5.

[0042] Reference Figure 2 The conveying mechanism 2 is used to convey the first material belt and the second material belt. It is set on the frame 1 and includes two feeding platforms 21 and a first driving component 22 for driving the two feeding platforms 21 to move independently. Each of the two feeding platforms 21 is provided with a positioning component 23, which is used to drive the first material belt or the second material belt to align with the edge.

[0043] Furthermore, the pressing mechanism includes two pressing belt assemblies 3, which are respectively disposed on two feeding platforms 21. The two pressing belt assemblies 3 are used to press the first material belt and the second material belt respectively.

[0044] Furthermore, the cutting and welding mechanism 4 is used to cut the ends of the first strip and the second strip and weld the first strip and the second strip together. It includes a first support 41, a second drive assembly 42 and a laser cutting and welding head 43. The first support 41 is mounted on the frame 1, and the second drive assembly 42 is mounted on the first support 41. The second drive assembly 42 is used to drive the laser cutting and welding head 43 to move along the width direction of the first strip or the second strip.

[0045] Furthermore, the weld leveling mechanism 5 is used to flatten the weld after welding.

[0046] First, the first and second material strips are placed on two feeding platforms 21 respectively. The two positioning components 23 push the first and second material strips close to one side of the reference edge to achieve edge alignment and ensure the consistency of the first and second material strips in the width direction.

[0047] Then, the two pressing assemblies 3 press the first and second material strips onto the corresponding feeding platforms 21 to prevent deviation during subsequent processing.

[0048] Next, the first drive assembly 22 drives the feeding platform 21 carrying the first strip to move to the cutting station. At this time, the feeding platform 21 carrying the second strip is in the avoidance position. Then, the laser cutting head 43 emits a laser for cutting. The second drive assembly 42 drives the laser cutting head 43 to move along the width direction of the first strip to cut off the end of the first strip and form a flat end face.

[0049] Subsequently, the first drive assembly 22 drives the two feeding platforms 21 to move together, so that the feeding platform 21 carrying the second material strip moves to the cutting station, and the feeding platform 21 carrying the first material strip is in the avoidance position. Then, the laser cutting head 43 emits a laser for cutting, and the second drive assembly 42 drives the laser cutting head 43 to move along the width direction of the second material strip to cut off the material head at the end of the second material strip to form a flat end face.

[0050] Next, the first drive assembly 22 drives the feeding platform 21 carrying the first strip to approach the feeding platform 21 carrying the second strip, so that the end face of the first strip abuts against the end face of the second strip. At this time, the laser cutting and welding head 43 switches the laser mode and emits a laser for welding. The second drive assembly 42 drives the laser cutting and welding head 43 to move along the width direction of the first strip or the second strip, welding the ends of the first strip and the second strip together.

[0051] After welding is completed, the first drive assembly 22 drives the two feeding platforms 21 to move together, so that the weld between the first strip and the second strip moves to the weld pressing station, and the weld leveling mechanism 5 flattens the weld after welding.

[0052] Therefore, this embodiment of the invention integrates multiple processes such as feeding, positioning, pressing, cutting, welding, and weld leveling onto a single device, achieving automated continuous production and greatly improving production efficiency. Furthermore, the two positioning components 23 align the first and second strips at their edges, ensuring welding accuracy. By setting a laser cutting and welding head, the cutting and welding processes of the strip can be combined, making the equipment compact. This also avoids frequent downtime for blade replacement due to wear of traditional cutters, ensuring continuous production. Moreover, the laser-cut strip has a smooth, burr-free end face, improving welding quality and strip strength. Finally, the weld leveling mechanism 5 ensures the flatness of the welded product, avoiding the risk of jamming the flow channel fixture or scratching the strip during high-speed winding and transmission.

[0053] In some preferred embodiments, the first drive assembly 22 includes a dual-movement linear module, and two feeding platforms 21 are respectively disposed on the two movers of the dual-movement linear module.

[0054] Understandably, the dual-mover linear module can independently control the movement of the two movers, which in turn drive the two feeding platforms 21 to perform linear motion. This results in a compact structure and improves the positioning accuracy of the first and second material strips.

[0055] Reference Figures 1 to 3 In some preferred embodiments, the pressing assembly 3 includes a second support 31, a first cylinder 32, and a pressing claw 33. The second support 31 is mounted on the feeding platform 21, the first cylinder 32 is mounted on the second support 31, and the pressing claw 33 is located at the telescopic end of the first cylinder 32. The pressing claw 33 is elongated, and its length extends along the width direction of the first or second strip. By driving the pressing claw 33 to descend as a whole through the first cylinder 32, it is possible to ensure that the first or second strip is pressed in the width direction. Moreover, the driving method of the first cylinder 32 is simple and quick, reducing the manufacturing cost of the equipment.

[0056] Furthermore, the pressure claw 33 includes an elongated support base 331 and a plurality of pressure blocks 332 disposed at the bottom of the elongated support base 331. The plurality of pressure blocks 332 are arranged sequentially along the length direction of the elongated support base 331, and a floating component 333 is disposed between the elongated support base 331 and the pressure blocks 332.

[0057] It is understandable that by setting the floating component 333, uneven pressing caused by uneven surface of the first or second material strip, impurities on the surface, or unevenness of the feeding platform 21 can be avoided. At the same time, it can also buffer the impact of the pressure block 332 on the first or second material strip, and prevent indentations or damage to the surface of the first or second material strip.

[0058] Specifically, the floating component 333 includes two bolts 3331 and two springs 3332. The shank of the bolt 3331 has a smooth shaft section and a threaded section. The elongated support base 331 is provided with two vertical through holes corresponding to the position of each pressure block 332. The top of the pressure block 332 is provided with two threaded holes corresponding to the through holes. The smooth shaft section passes through the through holes and can slide up and down. The spring 3332 is sleeved on the outer periphery of the smooth shaft section. The threaded section is threadedly connected to the threaded hole. The two ends of the spring 3332 abut against the bottom of the elongated support base 331 and the top of the pressure block 332, respectively.

[0059] Understandably, the spring 3332 provides preload, keeping the pressure block 332 in its lowest position under natural conditions. When the first cylinder 32 extends to drive the pressure claw 33 to descend as a whole, the bottom of the pressure block 332 first contacts the first or second material strip on the feeding platform 21. Then, the first cylinder 32 continues to extend, and the pressure block 332 is fixed by the supporting resistance. The elongated support seat 331 continues to descend. At this time, the spring 3332 is compressed, and the optical axis section of the bolt 3331 slides in the through hole of the support seat. The elastic force of the spring 3332 acts on the pressure block 332, causing the pressure block 332 to press the first or second material strip onto the feeding platform 21. Thus, it can be ensured that the first and second material strips can be pressed by the pressure block 332 at every position in the width direction.

[0060] Furthermore, the bottom of the elongated support base 331 is provided with a first receiving groove, and the top of the pressure block 332 is provided with a second receiving groove. The first receiving groove and the second receiving groove are respectively used to receive the two ends of the spring 3332. The first receiving groove and the second receiving groove respectively provide radial positioning for the two ends of the spring 3332, preventing the spring 3332 from being misaligned or tilted during operation, ensuring that the clamping force applied by the spring 3332 to the pressure block 332 is always vertically downward, and improving the reliability of the equipment.

[0061] In some preferred embodiments, the second drive assembly 42 includes a transverse linear module, the output end of which is provided with a mounting plate 421, and the laser cutting and welding head 43 is disposed on the mounting plate 421. The transverse linear module can drive the mounting plate 421 and the laser cutting and welding head 43 to perform high-speed, high-precision reciprocating linear motion along the width direction of the first or second strip, thereby improving the stability during laser cutting and welding.

[0062] Reference Figure 1 In some preferred embodiments, a laser (not shown in the figure) is provided in the frame 1. The laser cutting head 43 includes a laser isolator 431, a scanning galvanometer 432 and a focusing lens group 433. The laser emitted by the laser enters the laser isolator 431, causing the laser isolator 431 to generate a collimated spot and reach the focusing lens group 433 through the scanning galvanometer 432 to output a focused laser beam.

[0063] Reference Figure 4 In some preferred embodiments, the weld leveling mechanism 5 includes a third support 51, a second cylinder 52 disposed on the third support 51, a support 53 disposed on the telescopic end of the second cylinder 52, and a pressure roller 54 rotatably connected to the support 53. The third support 51 is disposed on the mounting plate 421.

[0064] Understandably, after laser welding is completed, the weld seam between the first and second strips moves directly under the pressure roller 54. Then, the second cylinder 52 drives the support 53 and the pressure roller 54 to descend, causing the pressure roller 54 to press the weld seam. Subsequently, the transverse linear module drives the mounting plate 421 and the weld seam leveling mechanism 5 to move along the width direction of the first strip. The pressure roller 54 rolls along the length direction of the weld seam to flatten it. This saves repositioning time and improves production efficiency. Moreover, the weld seam leveling mechanism 5 and the laser cutting head 43 share the same transverse linear module, making the equipment compact and saving space and cost.

[0065] Reference Figure 1 and Figure 5 In some preferred embodiments, an auxiliary feeding mechanism 6 is also provided on the frame 1. The auxiliary feeding mechanism 6 includes a fourth bracket 61, a support roller 62, a rubber roller 63, and a rotating handwheel 64. The fourth bracket 61 is provided on the frame 1. The support roller 62 and the rubber roller 63 are rotatably connected to the fourth bracket 61. The rubber roller 63 is located directly above the support roller 62. The top of the support roller 62 is flush with the top of the feeding platform 21. The rotating handwheel 64 is connected to one end of the rubber roller 63 through a reduction gear set 65.

[0066] Understandably, the material strip passes between the support roller 62 and the rubber roller 63. The operator can easily transport and guide the first or second material strip to the feeding platform 21 by rotating the rotary handwheel 64, which drives the rubber roller 63 to rotate through the reduction gear set 65, or transport the welded material strip to the outside. This reduces the labor intensity of the operator. At the same time, the rubber roller 63 can provide flexible friction drive to avoid hard scratches on the surface of the material strip. The support roller 62 is flush with the feeding platform 21, so that the material strip can transition smoothly.

[0067] The above is a detailed description of the preferred embodiments of the present utility model. However, the present utility model is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
