Description

Technical Field

[0001] The invention relates to the technical field of plate and strip welding, and in particular to an extremely thin plate and strip shaping device for a laser welding machine. Background Art

[0002] With the continuous upgrading of my country's industrial equipment, in the iron and steel metallurgical industry, more and more plate and strip post-processing production lines such as coating and plating lines, continuous annealing lines, and inspection lines will use laser welding machines (such as an automatic laser cutting and welding machine for the head and tail of the material strip and its processing technology disclosed in the application number 202410214139.X). In these extremely thin plate and strip production lines, laser welding machines play a vital role. Their function is to weld the tail of the previous roll of strip steel and the head of the next roll of strip steel in the plate and strip production line together to achieve continuous operation of the production line. Compared with traditional narrow lap resistance welding machines, the advantages of laser welding machines are fast welding speed, small weld heat affected zone, and no super-thick weld, which is conducive to the unit to produce better quality products. The plate and strip shaping device is an important component of the laser welding machine. Its main function is to press and flatten the head and tail of the plate and strip to be welded, realize laser welding, and continuously shape the plate and strip at the same time, so as to avoid the high and low staggered layers of the plate and strip to be welded, which is conducive to laser welding.

[0003] Existing strip shaping devices such as Figure 1 As shown, it includes a lower support wheel mechanism 100' and an upper support wheel mechanism 200', the lower support wheel mechanism 100' includes two lower wheel rims 110', the two lower wheel rims 110' are arranged opposite to each other, and a first V-shaped area 120' with an opening width gradually increasing from top to bottom is formed between the two lower wheel rims 110', and the two lower wheel rims 110' can rotate around their rotation axes, and the upper support wheel mechanism 200' includes two upper wheel rims 210', the two upper wheel rims 210' are arranged opposite to each other, and One-to-one correspondence with the two lower rims 110', a second V-shaped area 220' with an opening width gradually increasing from bottom to top is formed between the two upper rims 210', and the laser head 1' is arranged in the second V-shaped area 220'. The two upper rims 210' can move up and down, and can rotate around their rotation axes. The two upper rims 210' correspond one-to-one with the two lower rims 110' to form two shaping stations, and the belt head 2' and the belt tail 3' pass through the two shaping stations respectively. The above-mentioned plate and strip shaping device is installed as a whole on the frame. When the two upper rims move downward to the preset position, the plate and strip shaping device moves horizontally in a straight line under the drive of the driving mechanism. The two upper rims press the belt head and the belt tail respectively and then rotate. At this time, the laser beam emitted by the laser head converges at the joint of the belt head and the belt tail, realizing the function of continuous shaping of the plate and strip while laser welding, avoiding adverse effects such as high and low misalignment during plate and strip welding.

[0004] However, the plate strip shaping device is designed for medium and thick plates, and is only suitable for continuous shaping of plates and strips when laser welding medium and thick plates, but not for continuous shaping of plates and strips when laser welding ultra-thin plates. The upper tangent of the lower wheel rim is used as the positioning reference for the height direction of the plate and strip. It is difficult to adjust the upper tangents of the two lower wheel rims to the same height and parallel to each other, which easily causes the ultra-thin plates to have high and low layering, which is not conducive to laser welding. In addition, the overall mechanical structure of the device is relatively large, and the upper wheel rim has a large rotational resistance due to its large deadweight. In addition, since the upper wheel rim needs to move up and down, it has a driving mechanism and a certain downward pressure, which further increases the rotational resistance of the upper wheel rim. When shaping an ultra-thin plate and strip, it is easy to squeeze the plate and strip, causing wrinkles and changes in the gap between the joints, which is not conducive to laser welding. Summary of the invention

[0005] The purpose of the present invention is to overcome the above-mentioned technical deficiencies and propose an ultra-thin plate and strip shaping device for a laser welding machine to solve the technical problem that the upper tangent line of the lower wheel rim is used as the positioning reference in the height direction of the plate and strip in the prior art, which easily causes the ultra-thin plates to have high and low layer misalignment. The upper wheel rim has a large rotational resistance, and when shaping the ultra-thin plate and strip, it is easy to squeeze the plate and strip, causing wrinkles and changes in the gap between the joints, which is not conducive to laser welding.

[0006] In order to achieve the above technical objectives, the technical solution of the present invention provides an ultra-thin strip shaping device for a laser welding machine, comprising: Two clamping mechanisms are arranged opposite to each other, and include a reference piece and a clamping piece. A gap is formed between the two reference pieces, and the gap is used for the light beam of the laser head to pass vertically from top to bottom. The lower part of the reference piece has a clamping section away from the gap and a shaping section close to the gap. The clamping piece is arranged in the clamping section, and the tape head or tape tail is placed on the clamping piece. The clamping piece can move up and down to clamp the tape head or tape tail together with the reference piece. The two shaping mechanisms are relatively arranged directly below the laser head and correspond one-to-one to the two shaping intervals. The two shaping mechanisms and the laser head can perform synchronous reciprocating linear horizontal movement along the length direction of the gap in the horizontal plane. The shaping mechanism includes a roller, which is rotatably abutted against the head or tail of the belt.

[0007] Furthermore, the bottom surface of the reference member is a horizontal plane, and the top surface of the clamping member is a horizontal plane.

[0008] Furthermore, a horizontal tangent line of the roller extends along the length direction of the gap.

[0009] Furthermore, the shaping mechanism also includes a base, a wheel frame, at least two guide rods and an elastic component. The two bases and the laser head can make synchronous reciprocating linear horizontal movements in a horizontal plane along the length direction of the gap. The wheel frame is arranged above the base, and the roller is rotatably arranged on the wheel frame. Each of the guide rods is arranged at intervals along the length direction of the gap. The lower end of each of the guide rods slides through the base, and the upper end of each of the guide rods is hinged to the bottom of the wheel frame so that the wheel frame can rotate along the width direction of the gap and the inclination angle of the roller can be adjusted. The elastic component includes at least two first elastic members and a second elastic member. Each of the first elastic members is respectively sleeved on the corresponding guide rods, the lower end of each of the first elastic members is connected to the base, and the upper end of each of the first elastic members is connected to the wheel frame so that the top of the roller is higher than the lower surface of the reference member. The second elastic member is arranged on the outside of each of the first elastic members, the lower end of the second elastic member is connected to the base, and the upper end of the second elastic member is connected to the wheel frame so that the roller is in a vertical state.

[0010] Furthermore, the elastic component also includes at least two spacers, each of which is slidably mounted on the corresponding guide rod and is located above the first elastic member, and the upper end of the first elastic member is connected to the spacer.

[0011] Furthermore, the shaping mechanism also includes at least two limiting members, each of which is detachably connected to the lower end of each of the guide rods in a one-to-one correspondence to limit the up and down movement distance of the guide rods.

[0012] Furthermore, the shaping mechanism also includes at least two second connecting members, one end of each of the second connecting members is hinged to the upper end of each of the guide rods in a one-to-one correspondence, and the other end of each of the second connecting members is hinged to the bottom of the wheel frame.

[0013] Furthermore, the shaping mechanism also includes a positioning member, which is arranged between the base and the wheel frame, and the lower end of the positioning member is detachably fixedly connected to the base, and the second elastic member is sleeved on the positioning member.

[0014] Furthermore, the lower surface of the end portion of the reference member has an inclined structure.

[0015] Furthermore, the ultra-thin plate and strip shaping device for the laser welding machine also includes a driving mechanism, which is connected to the two bases and the laser head, and is used to drive the two bases and the laser head to perform synchronous reciprocating linear horizontal movement along the length direction of the gap in the horizontal plane.

[0016] Compared with the prior art, the beneficial effects of the present invention include: when in use, the belt head and the belt tail are placed on two clamping members respectively, and then the clamping members are operated to move upward until the clamping members and the corresponding reference members clamp the belt head or the belt tail together, and the joints and gaps of the belt head and the belt tail correspond to each other, and then the two shaping mechanisms and the laser head are operated to perform synchronous reciprocating linear horizontal movement in the horizontal plane along the length direction of the gap, and the two rollers and the laser head gradually approach the two clamping mechanisms and continue to move horizontally. Since the rollers can be aligned with the belt head or the belt tail, the two shaping mechanisms and the laser head can be moved horizontally. The tail of the belt rotates and abuts against it, so that the head or tail of the belt can be shaped, and the light beam emitted by the laser head passes through the gap to weld the joint. The ultra-thin plate and strip shaping device used for the laser welding machine adopts a roller to press the head or tail of the belt on a fixed reference plane, ensuring that the head and tail of the belt to be welded can be highly aligned in the high and low directions, effectively ensuring the accuracy of ultra-thin plate welding, and adopting a lightweight roller design. The roller rotation resistance is very small. When the roller continuously rotates to shape the ultra-thin plate, the gap of the ultra-thin plate will not be squeezed and changed.

DETAILED DESCRIPTION

[0017] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0018] The present invention provides an ultra-thin strip shaping device for a laser welding machine, the structure of which is as follows: Figure 2 - Figure 5 As shown, it includes two clamping mechanisms 100 and two shaping mechanisms 200. The two clamping mechanisms 100 are arranged opposite to each other. The clamping mechanism 100 includes a reference member 110 and a clamping member 120. A gap 111 is formed between the two reference members 110. The gap 111 is used for the light beam of the laser head 1 to pass vertically from top to bottom. The lower part of the reference member 110 has a clamping section 112 away from the gap 111 and a shaping section 113 close to the gap 111. The clamping member 120 is arranged in the clamping section 112. The clamping member 120 is used to place the tape head 2 or the tape tail 3, and the clamping member 120 can move up and down to clamp the tape head 2 or the tape tail 3 together with the reference member 110; the two shaping mechanisms 200 are relatively arranged directly below the laser head 1, and correspond one to one with the two shaping intervals 113, and the two shaping mechanisms 200 and the laser head 1 can make synchronous reciprocating linear horizontal movements in a horizontal plane along the length direction of the gap 111, and the shaping mechanism 200 includes a roller 210, and the roller 210 is rotatably abutted against the tape head 2 or the tape tail 3.

[0019] When in use, the tape head 2 and the tape tail 3 are placed on the two clamping members 120 respectively, and then the clamping members 120 are operated to move upward until the clamping members 120 and the corresponding reference members 110 clamp the tape head 2 or the tape tail 3 together, and make the joints of the tape head 2 and the tape tail 3 correspond to each other in the gap 111, and then the two shaping mechanisms 200 and the laser head 1 are operated to make synchronous reciprocating linear horizontal movements in the horizontal plane along the length direction of the gap 111, and the two rollers 210 and the laser head 1 gradually approach the two clamping mechanisms 100 and continue to move horizontally. The belt head 2 or the belt tail 3 rotates and abuts against each other, so that the belt head 2 or the belt tail 3 can be shaped, and the light beam emitted by the laser head 1 passes through the gap 111 to weld the joint. The ultra-thin plate strip shaping device used for the laser welding machine adopts the roller 210 to press the belt head 2 or the belt tail 3 on a fixed reference plane, ensuring that the belt head 2 and the belt tail 3 to be welded can be highly flush in the vertical direction, effectively ensuring the accuracy of ultra-thin plate welding, adopting the lightweight design of the roller 210, the rotation resistance of the roller 210 is very small, and when the roller 210 continuously rotates to shape the ultra-thin plate, the gap of the ultra-thin plate will not be squeezed and changed.

[0020] As a preferred embodiment, please refer to Figure 2 and Figure 3 The bottom surface of the reference member 110 is a horizontal plane, and the top surface of the clamping member 120 is a horizontal plane, so that the belt head 2 or the belt tail 3 clamped by the clamping member 120 and the reference member 110 can maintain a flat state.

[0021] As a preferred embodiment, please refer to Figure 3 and Figure 4 The horizontal tangent of the roller 210 extends along the length direction of the gap 111, so that the roller 210 can rotate to shape the extremely thin plate.

[0022] As a preferred embodiment, please refer to Figure 3 and Fig.10The shaping mechanism 200 also includes a base 220, a wheel frame 230, at least two guide rods 240 and an elastic component 250. The two bases 220 and the laser head 1 can make synchronous reciprocating linear horizontal movements in a horizontal plane along the length direction of the gap 111. The wheel frame 230 is arranged above the base 220, and the roller 210 is rotatably arranged on the wheel frame 230. Each of the guide rods 240 is arranged at intervals along the length direction of the gap 111. The lower end of each of the guide rods 240 slides through the base 220, and the upper end of each of the guide rods 240 is hinged to the bottom of the wheel frame 230, so that the wheel frame 230 can rotate along the width direction of the gap 111 and the roller 210 can rotate. The inclination angle of the wheel 210 is adjustable. The elastic component 250 includes at least two first elastic members 251 and a second elastic member 252. Each of the first elastic members 251 is respectively sleeved on the corresponding guide rod 240. The lower end of each of the first elastic members 251 is connected to the base 220, and the upper end of each of the first elastic members 251 is connected to the wheel frame 230, so that the top of the roller 210 is higher than the lower surface of the reference member 110. The second elastic member 252 is arranged on the outer side of each of the first elastic members 251. The lower end of the second elastic member 252 is connected to the base 220, and the upper end of the second elastic member 252 is connected to the wheel frame 230, so that the roller 210 is in In the vertical state, the structure of the shaping mechanism 200 enables the roller 210 to have the function of lateral rotation, ensuring that the roller 210 can always fit closely to the bottom surface of the reference member 110. The structure of the shaping mechanism 200 also enables the roller 210 to have the function of floating up and down. At the same time, the structure of the shaping mechanism 200 provides a driving force for the lateral rotation adjustment function of the roller 210, ensuring that the roller 210 can always fit closely to the bottom surface of the reference member 110. Because the lateral center of the guide rod 240 coincides with the roller 210, and the position of the wheel frame 230 is offset to the outside of the roller 210, the lateral rotation force of the entire shaping mechanism 200 in the free state is The roller 210 is uneven, with the outer side being heavier. The function of the second elastic member 252 is to provide a lateral force for the lateral rotation of the roller 210 to offset the unbalanced gravity when it is biased toward the outside, so that the entire shaping mechanism 200 is balanced, and the roller 210 can be arranged vertically in the initial state. When the roller 210 contacts the plate strip, the first elastic member 251 and the second elastic member 252 are both compressed. After the roller 210 contacts the plate strip, there is an upward pressing force. In addition, the roller 210 has the function of lateral rotation, and can be freely adjusted back to the center under the action of the first elastic member 251 and the second elastic member 252, thereby achieving the purpose of continuously shaping the plate strip while welding the plate strip.

[0023] As a preferred embodiment, please refer to Figure 3 and Fig.10 The elastic component 250 also includes at least two spacers 253, each of which is slidably mounted on the corresponding guide rod 240 and is located above the first elastic member 251. The upper end of the first elastic member 251 is connected to the spacer 253 so that the first elastic member 251 applies a force to the wheel frame 230 through the spacer 253.

[0024] As a preferred embodiment, please refer to Figure 3 and Fig.10 The shaping mechanism 200 also includes at least two limit members 260, each of which is detachably connected to the lower end of each guide rod 240 in a one-to-one correspondence to limit the up and down movement distance of the guide rod 240, so that the guide rod 240 can move up and down within a range.

[0025] As a preferred embodiment, please refer to Figure 3 and Fig.10 The limiting member 260 includes a washer 261 and two first nuts 262. The washer 261 is arranged below the base 220 and slidably sleeved on the guide rod 240. The lower end of the guide rod 240 is provided with a first thread. The two first nuts 262 are both arranged below the washer 261 and sleeved on the guide rod 240. The two first nuts 262 are both threadedly connected with the first thread. When the roller 210 is located at the initial position, the washer 261 abuts against the bottom surface of the base 220, so that the upward displacement distance of the guide rod 240 can be limited, and the structure of the limiting member 260 is convenient for disassembly and assembly.

[0026] As a preferred embodiment, please refer to Figure 3 and Fig.10 At least two guide holes 221 are formed on the base 220, and the lower ends of the guide rods 240 slide through the corresponding guide holes 221 respectively. The limiting member 260 also includes a steel ball sleeve 263, and each of the steel ball sleeves 263 is respectively arranged in the corresponding guide hole 221 and is respectively fixedly sleeved on the corresponding guide rod 240. When the roller 210 is located at the initial position, the top surface of the steel ball sleeve 263 abuts against the top surface of the guide hole 221, thereby further improving the limiting effect on the guide rod 240.

[0027] As a preferred embodiment, please refer to Figure 3 and Fig.10The shaping mechanism 200 also includes a first connecting member 270, one end of which is detachably fixedly connected to the roller 210, and the other end of the first connecting member 270 is hinged to the wheel frame 230, so that the roller 210 can rotate relative to the wheel frame 230. As a preferred embodiment, please refer to Figure 4 and Fig.10 The shaping mechanism 200 also includes at least two second connecting members 280, one end of each of the second connecting members 280 is hinged to the upper end of each of the guide rods 240, and the other end of each of the second connecting members 280 is hinged to the bottom of the wheel frame 230, so that the wheel frame 230 can rotate relative to each of the guide rods 240.

[0028] As a preferred embodiment, please refer to Fig.10 The wheel frame 230 is an L-shaped structure, which includes a vertical plate 231 and at least two ear seats 232. Each ear seat 232 is fixed to the inner side of the vertical plate 231. The vertical plate 231 is provided with a mounting hole. The first connecting member 270 includes a wheel shaft 271, a flat washer 272 and a bolt 273. The wheel shaft 271 has three steps. The inner ring of the roller 210 is installed on the first step of the wheel shaft 271 by interference fit and abuts against the second step of the wheel shaft 271. The third step of the wheel shaft 271 rotates through the mounting hole. The second step of the wheel shaft 271 abuts against the inner side of the vertical plate 231. The flat washer 272 is arranged on the outer side of the vertical plate 231. The bolt 273 passes through the flat washer 272 and is locked in the thread hole at the rear end of the wheel axle 271, ensuring that the wheel axle 271 will not have lateral displacement. The ear seat 232 is provided with a first through hole extending along the length direction of the gap 111, and the upper end of the guide rod 240 is provided with a second through hole. The second connecting member 280 includes a pin 281 and a second nut 282. The pin 281 rotates through the corresponding first through hole and the second through hole. The step at one end of the pin 281 abuts against the ear seat 232. The other end of the pin 281 is provided with a second thread. The second nut 282 is sleeved on the other end of the pin 281 and is threadedly connected with the second thread.

[0029] As a preferred embodiment, please refer to Figure 7When a downward force is applied to the shaping mechanism 200, the shaping mechanism 200 moves downward under the guidance of each of the guide rods 240. When the steel ball sleeve 263 slides downward, the steel ball sleeve 263 is away from the top surface of the guide hole 221, and there is a gap between its top surface and the top surface of the guide hole 221. The gasket 261 is also away from the bottom surface of the base 220. At this time, each of the first elastic members 251 is in a compressed state, and the second elastic member 252 is in a compressed state. When the applied external force is removed, the shaping mechanism 200 will move upward under the action of each of the first elastic members 251 and the second elastic member 252. When the steel ball sleeve 263 slides upward, the steel ball sleeve 263 is close to the top surface of the guide hole 221 until its top surface abuts against the top surface of the guide hole 221, and the gasket 261 also abuts against the bottom surface of the base 220, returning to its initial state.

[0030] As a preferred embodiment, please refer to Figure 6 When a rotational force is applied to the shaping mechanism 200 toward the outside, the wheel frame 230 and the roller 210 will swing to the corresponding position. At this time, the outer side of the bottom surface of the wheel frame 230 will press the spacer 253 downward, and the spacer 253 will move downward to press the first elastic member 251. The first elastic member 251 is in a compressed state, and a gap 111 is generated between the inner side of the bottom surface of the wheel frame 230 and the spacer 253. At this time, the second elastic member 252 is also in a compressed state. There is an upward force on the second elastic member 252. When the applied force is withdrawn, the first elastic member 25 1, the spacer 253 will apply an upward force to the outer side of the wheel frame 230. Since there is a gap 111 between the inner side of the wheel frame 230 and the spacer 253, the inner side of the wheel frame 230 is not subjected to the upward force. When the applied external force is removed, the upward force applied to the wheel frame 230 is all on the outer side, so the roller 210 will rotate and swing inward until the top of the spacer 253 completely contacts the bottom surface of the wheel frame 230, so that the roller 210 returns to a balanced state. When an inward rotational force is applied to the shaping mechanism 200, the result is similar to the above description and will not be repeated.

[0031] As a preferred embodiment, please refer to Figure 4 and Fig.10 The shaping mechanism 200 also includes a positioning member 290, which is arranged between the base 220 and the wheel frame 230. The lower end of the positioning member 290 is detachably fixedly connected to the base 220, and the second elastic member 252 is sleeved on the positioning member 290, so that the second elastic member 252 can be positioned.

[0032] As a preferred embodiment, please refer to Figure 4 and Fig.10 The positioning member 290 includes a pad 291 and a screw 292. The pad 291 is placed on the base 220. The screw 292 passes through the pad 291 and pushes into the base 220. The screw 292 is screwed to the pad 291 and the base 220. The second elastic member 252 is sleeved on the screw 292. The lower end of the second elastic member 252 is connected to the pad 291, so that the second elastic member 252 can be positioned to prevent the second elastic member 252 from being deformed.

[0033] As a preferred embodiment, please refer to Fig.10 A flow hole is formed between the two bases 220, and the flow hole corresponds to the laser head 1 for the laser beam to pass through. Since the laser beam is emitted in advance, the laser beam can pass through the flow hole and irradiate the receiving box below, thereby preventing the laser beam from irradiating the base 220 and causing damage to the base 220.

[0034] As a preferred embodiment, please refer to Figure 4 and Figure 5 The lower surface of the end of the reference member 110 has a slope 114 structure. When the two shaping mechanisms 200 and the laser head 1 gradually approach the two clamping mechanisms 100, the roller 210 will contact the slope 114. Under the pressure of the slope 114, the roller 210 will move downward until the roller 210 contacts the bottom surface of the reference member 110.

[0035] As a preferred embodiment, the clamping mechanism 100 also includes a driving component, which is connected to the clamping member 120 and is used to drive the clamping member 120 to move up and down, so that the clamping member 120 can work together with the reference member 110 to clamp the belt head 2 or the belt tail 3.

[0036] As a preferred embodiment, the ultra-thin plate and strip shaping device for a laser welding machine also includes a driving mechanism, which is connected to the two bases 220 and the laser head 1, and is used to drive the two bases 220 and the laser head 1 to perform synchronous reciprocating linear horizontal movement in a horizontal plane along the length direction of the gap 111.

[0037] In order to better understand the present invention, the following Figure 1 - Fig.10 The working principle of the technical solution of the present invention is described in detail: When in use, the tape head 2 and the tape tail 3 are placed on the two clamping members 120 respectively, and the driving assembly is controlled to drive the clamping member 120 to move upward, so that the clamping member 120 can work together with the reference member 110 to clamp the tape head 2 or the tape tail 3, and make the joints of the tape head 2 and the tape tail 3 correspond to the gap 111, and then the driving mechanism is controlled to drive the two bases 220 and the laser head 1 to move synchronously along the length direction of the gap 111 in the horizontal plane. The two bases 220 and the laser head 1 gradually move horizontally in a straight line, and the two bases 220 and the laser head 1 gradually approach the two clamping mechanisms 100. When the two shaping mechanisms 200 and the laser head 1 gradually approach the two clamping mechanisms 100, the roller 210 will contact the inclined surface 114. Under the pressure of the inclined surface 114, the roller 210 will move downward until the roller 210 contacts the bottom surface of the reference member 110. As the two bases 220 and the laser head 1 continue to move, the roller 210 will contact the tape head 2 or The roller 210 can be rotatably abutted against the belt head 2 or the belt tail 3, so that the belt head 2 or the belt tail 3 can be shaped. When the roller 210 contacts the plate strip, the first elastic member 251 and the second elastic member 252 are both compressed. After the roller 210 contacts the plate strip, there is an upward pressing force. In addition, the roller 210 has the function of lateral rotation, and can be freely adjusted back to the center under the action of the first elastic member 251 and the second elastic member 252, so that the plate strip can be continuously shaped while welding the plate strip. For the purpose of shaping, the light beam emitted by the laser head 1 passes through the gap 111 to weld the joint. The ultra-thin plate strip shaping device for the laser welding machine adopts the roller 210 to press the strip head 2 or the strip tail 3 on a fixed reference plane, ensuring that the strip head 2 and the strip tail 3 to be welded can be highly flush in the vertical direction, effectively ensuring the accuracy of ultra-thin plate welding. The roller 210 is lightweight in design, and the rotation resistance of the roller 210 is very small. When the roller 210 continuously rotates to shape the ultra-thin plate, the gap of the ultra-thin plate will not be squeezed and changed.

[0038] The ultra-thin strip shaping device for a laser welding machine provided by the present invention has the following beneficial effects: (1) The ultra-thin strip shaping device for the laser welding machine concentrates the driving force for the upward reset and the lateral rotation reset of the roller 210 on the same power source, making the overall structure simple and practical; (2) The ultra-thin strip shaping device for the laser welding machine, when the roller 210 contacts the strip, the first elastic member 251 and the second elastic member 252 are both compressed, and there is an upward pressing force after the roller 210 contacts the strip. The roller 210 has the function of automatic adjustment of up and down floating and lateral rotation. After the roller 210 presses the strip, it can automatically adjust the angle according to the situation of the reference surface, ensuring that the roller 210 always keeps the strip close to the reference surface, achieving the purpose of continuously shaping the strip while welding the strip, and can be freely adjusted back to the original position under the action of the first elastic member 251 and the second elastic member 252; (3) This ultra-thin strip shaping device for laser welding machine is used in ultra-thin strip online laser welding machine. It has a compact structure, reasonable layout, and complete functions. It can greatly improve the welding accuracy of ultra-thin plates, making the overall device more practical and stable, and more convenient for maintenance. In the future, it will be used in all ultra-thin plate laser welding machines of the company, which can greatly improve product performance and make the equipment more competitive in the market; (4) The ultra-thin plate strip shaping device used in the laser welding machine adopts the roller 210 to press the strip head 2 or the strip tail 3 on a fixed reference plane, ensuring that the strip head 2 and the strip tail 3 to be welded can be highly flush in the vertical direction, effectively ensuring the accuracy of ultra-thin plate welding. The roller 210 is lightweight in design, and the rotation resistance of the roller 210 is very small. When the roller 210 continuously rotates to shape the ultra-thin plate, the gap of the ultra-thin plate will not be squeezed and changed.
