Description

Technical Field

[0001] This utility model relates to the field of laser welding machine technology, and specifically to a laser welding machine wire feeding device. Background Technology

[0002] With the continuous upgrading of my country's industrial equipment, more and more production lines, such as high-strength steel production lines, stainless steel production lines, and silicon steel production lines, are adopting laser welding machines. In these strip production lines, the welding machine plays a crucial role, connecting the tail of one coil of strip steel to the head of the next, enabling continuous operation of the production line. However, compared to other sheet metal production lines, these lines have poorer weldability, thus placing higher demands on the welding machine. Achieving good weld quality is essential, making the wire feeder device extremely important.

[0003] Laser welding machines typically include a drive system, a wire feeding mechanism, and protective components. During welding, the wire feeding mechanism and protective components are driven by two independent systems. That is, the two protective components need to move downwards to the welding position first, and then the wire feeding mechanism moves downwards to the welding position. If the movement sequence is incorrect, the wire feeding mechanism and the protective components will collide, damaging the wire feeding mechanism and affecting its service life. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and provide a laser welding machine wire filling device, which solves the problem that the movement of the wire filling mechanism and the protective component are independent in the prior art, and that collisions are easy to occur between the wire filling mechanism and the protective component.

[0005] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution:

[0006] This utility model provides a wire-filling device for a laser welding machine, comprising:

[0007] A filler mechanism, comprising a mounting base and a filler element, the filler element being movably connected to the mounting base and capable of vertical movement relative to the mounting base; and,

[0008] Two adjustment mechanisms are respectively located on opposite sides of the filling mechanism. Each adjustment mechanism includes a telescopic member and a protective member. The movable end of the telescopic member is connected to the protective member. Both sides of the filling member abut against the protective member so that the protective member supports the filling member and restricts the filling member from sliding downward relative to the mounting base. The two telescopic members drive the two protective members to rise and fall respectively, so that the filling member can slide relative to the mounting base, and the filling member can maintain contact with at least one protective member.

[0009] In some embodiments, the filler includes a movable part and a filler nozzle, the movable part being movably connected to the mounting base, the filler nozzle being fixedly connected to the movable part, and the opposite sides of the movable part being able to abut against the two protective members respectively.

[0010] In some embodiments, the movable part includes a sliding plate, an adjusting plate, and two protrusions. The sliding plate is slidably connected to the mounting base along a first direction, and the adjusting plate is slidably connected to the sliding plate along a second direction, wherein the first direction and the second direction are perpendicular to each other. The two protrusions are disposed on opposite sides of the adjusting plate and can respectively abut against the two protective members. The adjusting plate is fixedly connected to the filler nozzle.

[0011] In some embodiments, the end of the protrusion that abuts against the protective member is arc-shaped.

[0012] In some embodiments, at least one locking module is provided on each of the opposite sides of the slide plate, and the adjusting plate can be fixed between the two opposite locking modules.

[0013] In some embodiments, the locking module includes a mounting block and a locking rod. The mounting block is fixedly connected to the slide plate, and the locking rod is threadedly rotatably connected to the mounting block. By rotating the locking rod, one end of the locking rod can abut against the adjusting plate.

[0014] In some embodiments, the adjusting plate is provided with clearance grooves on both sides, and one end of the locking rod can extend into the clearance groove and abut against the adjusting plate.

[0015] In some embodiments, a grip is slidably provided on one of the mounting blocks, and one end of the grip is connected to the adjustment plate. By pushing or pulling the grip, the adjustment plate can be driven to slide back and forth in a second direction.

[0016] In some embodiments, the protective member includes a base and a protective block. The base is connected to the movable end of the telescopic member, and the protective block is connected to the base. When the two bases abut against the two protrusions respectively, the filler nozzle is located between the two protective blocks, and a welding space corresponding to the filler nozzle is formed between the two protective blocks.

[0017] In some embodiments, the protective block is rotatably connected to the base, and the protective block is generally wheel-shaped.

[0018] Compared with the prior art, the present invention provides a laser welding machine wire filling device, in which the wire filling component is movably connected to the mounting base and can move up and down relative to the mounting base. The movable end of the telescopic component is connected to the protective component, and the two sides of the wire filling component abut against the protective component so that the protective component supports the wire filling component and restricts the wire filling component from sliding downward relative to the mounting base. The two telescopic components drive the two protective components to move up and down respectively, so that the wire filling component can slide relative to the mounting base. The wire filling component can maintain contact with at least one protective component, ensuring that mechanical collisions are not likely to occur between the wire filling component and the protective component, and the probability of failure is lower.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0025] To address the technical problem that the movements of the wire filling mechanism and the protective component are independent, and that collisions easily occur between them, this invention provides a wire filling device for a laser welding machine. This device reduces the likelihood of mechanical collisions between the wire filling mechanism and the protective component, lowers the probability of failure, and thus extends the service life of the wire filling mechanism.

[0026] Please see Figures 1-5 , Figures 1-5According to one embodiment of the present invention, a wire-filling device for a laser welding machine includes a wire-filling mechanism 1 and two adjusting mechanisms 2. The wire-filling mechanism 1 includes a mounting base 11 and a wire-filling component 12. The wire-filling component 12 is movably connected to the mounting base 11 and can move up and down relative to the mounting base. The two adjusting mechanisms 2 are respectively disposed on opposite sides of the wire-filling mechanism 1. The adjusting mechanism 2 includes a telescopic component 21 and a protective component 22. The movable end of the telescopic component 21 is connected to the protective component 22. The two sides of the wire-filling component 12 abut against the protective component 22 so that the protective component 22 supports the wire-filling component 12 and restricts the wire-filling component 12 from sliding downward relative to the mounting base. The two telescopic components 21 drive the two protective components 22 to move up and down respectively, so that the wire-filling component 12 can slide relative to the mounting base 11, and the wire-filling component 12 can maintain contact with at least one of the protective components 22.

[0027] It should be noted that one of the welding steps is for the laser welding machine's clamps to move the strip to the welding position, where wire feeding is performed simultaneously. If the wire feeding deviates during this step, the welding wire cannot be accurately placed into the weld, leading to situations such as the welding wire not being completely melted by the laser, wire misalignment (piled up on one side and missing on the other), or the welding wire not contacting the laser, which will inevitably affect the welding quality.

[0028] In actual use, the two telescopic members 21 drive the two protective members 22 to descend until the two protective members 22 come into contact with the two strips to be welded. At this time, the filler 12 can be aligned with the weld between the two strips. When the thickness of the two strips is different, one protective member 22 can come into contact with the thicker strip during the descent, while the other protective member 22 can continue to descend and separate from the filler 12 until it comes into contact with the thinner strip, ensuring that the filler 12 is aligned with the weld between the two strips.

[0029] In this specific embodiment, the mounting base 11 is not limited to a specific structure. When in use, the mounting base 11 needs to be fixed. The mounting base 11 is provided with a slide rail, and the filler 12 is slidably connected to the mounting base 11 through the slide rail.

[0030] It should be noted that the filler 12 is not limited to a specific structure, as long as it can fill the weld with welding wire, no further details will be provided here.

[0031] In this specific embodiment, the filler 12 includes a movable part 121 and a filler nozzle 122. The movable part 121 is movably connected to the mounting base 11, and the filler nozzle 122 is fixedly connected to the movable part 121. The opposite sides of the movable part 121 can respectively abut against the two protective members 22.

[0032] Specifically, the movable part 121 includes a sliding plate 1211, an adjusting plate 1212, and two protrusions 1213. The sliding plate 1211 is slidably connected to the mounting base 11 along a first direction, and the adjusting plate 1212 is slidably connected to the sliding plate 1211 along a second direction, with the first direction and the second direction being perpendicular to each other. The two protrusions 1213 are located on opposite sides of the adjusting plate 1212 and can respectively abut against the two protective members 22. The adjusting plate 1212 is fixedly connected to the filler nozzle 122.

[0033] It should be noted that the height of the filler nozzle 122 can be adjusted by sliding the slide plate 1211 along the first direction, and the horizontal position of the filler nozzle 122 can be adjusted by sliding the adjustment plate 1212 along the second direction.

[0034] Based on the above scheme, the end of the protrusion 1213 that abuts against the protective member 22 is arc-shaped. In this specific embodiment, the protrusion 1213 is a support bolt. Since the center of laser welding and the center of the movable end of the telescopic member are not on the same straight line, when the movable end of the telescopic member extends to the lower position, there will be a force that causes the protective member 22 to tilt and twist. If the bottom of the protrusion 1213 is a normal bolt style (flat), then a small amount of tilting and twisting will cause the filler nozzle to change in height. Therefore, designing the bottom of the support bolt as arc-shaped can greatly reduce the error caused by deformation during the use of the device.

[0035] It should be noted that, in order to limit the horizontal position of the filler nozzle 122, specifically, at least one locking module 3 is provided on each of the opposite sides of the slide plate 1211, and the adjusting plate 1212 can be fixed between the two opposite locking modules 3.

[0036] In this specific embodiment, two locking modules 3 are provided at intervals on both sides of the sliding plate 1211, that is, the adjusting plate 1212 is fixed by four locking modules 3. Specifically, the locking module 3 includes a mounting block 31 and a locking rod 32. The mounting block 31 is fixedly connected to the sliding plate 1211, and the locking rod 32 is threadedly rotatably connected to the mounting block 31. By rotating the locking rod 32, one end of the locking rod 32 can abut against the adjusting plate 1212.

[0037] It should be noted that the mounting block 31 has an internal thread, and the locking rod 32 has an external thread that engages with the internal thread. The position of the locking rod 32 can be adjusted by engaging the external thread with the internal thread. That is, when it is necessary to slide the adjusting plate 1212 in the second direction, the locking rod 32 can be rotated to make the two locking rods 32 move away from each other. When it is necessary to fix the adjusting plate 1212, the locking rod 32 can be rotated to make the two locking rods 32 move closer together.

[0038] In addition, both sides of the adjusting plate 1212 are provided with clearance grooves 121a, and one end of the locking rod 32 can extend into the clearance grooves 121a and abut against the adjusting plate 1212.

[0039] Based on the above scheme, a gripping rod 33 is slidably provided on the mounting block 31, and one end of the gripping rod 33 is connected to the adjusting plate 1212. Specifically, the operator can push and pull the gripping rod 33 to drive the adjusting plate 1212 to slide back and forth in the second direction, thereby adjusting the position of the adjusting plate 1212 and ensuring that the filler nozzle 122 is aligned with the weld position.

[0040] In this specific embodiment, the telescopic member 21 is a pneumatic cylinder. Of course, in other embodiments, the telescopic member 21 can also be an electric cylinder or a hydraulic cylinder. In addition, the mounting base is also provided with a sleeve, and the movable end of the telescopic member 21 is slidably connected to the sleeve.

[0041] Specifically, the protective component 22 includes a base 221 and a protective block 222. The base 221 is connected to the movable end of the telescopic component 21, and the protective block 222 is connected to the base 221. When the two bases 221 abut against the two protrusions 1213 respectively, the filler nozzle 122 is located between the two protective blocks 222, and a welding space corresponding to the filler nozzle 122 is formed between the two protective blocks 222.

[0042] In one embodiment, the protective block 222 is rotatably connected to the seat 221, and the protective block 222 is generally wheel-shaped, with the edge of the protective block 222 capable of rolling contact with the strip steel.

[0043] Specifically, the width between welding spaces can be designed according to actual needs. It should be noted that when the filler nozzle 122 is located in the welding space, the filler nozzle 122 will not contact the two protective blocks 222. When welding two strips, the two protective blocks 222 contact the two strips respectively. The two protective blocks 222 can block the high-temperature welding slag generated during the welding process, prevent welding slag and sparks from splashing to surrounding personnel or equipment, and reduce the risk of accidents such as fire and electric shock.

[0044] To better understand this utility model, the following is combined with... Figures 1 to 5 The technical solution of this utility model is described in detail below:

[0045] When welding two steel strips is required, the strips can be clamped and moved to the welding position using the clamps of the laser welding machine. Since the two protective components 22 descend under the driving force of the telescopic components, the synchronization of the two telescopic components 21 is often not ideal in actual use. If one protective component 22 moves first and the other moves later, the other protective component 22 will abut against a protrusion 1213. Therefore, the filler will not fall, and no mechanical collision will occur. The filler will move to the welding position along with the later-moving protective component 22, at which point welding can be performed. After welding is completed, the first-rising protective component 22 will drive the filler to move upwards together until both protective components return to their original positions, ending one work cycle. The process does not require interlocking; the orderly movement is achieved through the mechanical structure.

[0046] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
