Description

Technical Field

[0001] The present invention relates to the technical field of welding, in particular to automatic steel plate welding equipment. Background Art

[0002] With the rapid development of society, the types of products that need to be welded are increasing, and people's requirements for product quality are constantly improving, which makes people's demand and requirements for automatic welding equipment increasingly higher.

[0003] When welding steel plates, a laser gun is usually used to melt the steel plate material and the solder. The molten welding wire and the material body are mixed to form a molten pool. The molten pool cools and solidifies to form a weld. When welding the ends and tails of the steel plate welds, the molten pool is affected by the surface tension of the liquid, which usually causes gaps at the ends and tails of the welds. The gaps at the ends or tails of the welds increase the risk of cracking of the parts during subsequent stamping. To solve this problem, the invention patent with application number CN202410146739.7 provides a laser wire-filling welding device and a welding method. The welding device fills the gap by adding solder. The method controls the wire feeding speed and the wire feeding time according to different steel plates to avoid too little or too much solder affecting the welding quality. When brazing steel plates, the solder is usually placed at the weld by a paste dispenser. Therefore, it is difficult to control the amount of solder, resulting in the problem of gaps at the ends and tails of the welds still being prone to occur during the brazing process of the steel plates.

[0004] In order to avoid the occurrence of notches at the ends and tails of welds and ensure the welding quality of steel plates, an automatic steel plate welding device is proposed. Summary of the Invention

[0005] The purpose of the present invention is to provide an automatic steel plate welding equipment. In order to avoid the occurrence of notches at the ends and tails of the welds, the hot-melt solder inside the molten pool is adsorbed and drained during the welding process so that the hot-melt solder can flow to the ends and tails of the welds, thereby avoiding the occurrence of notches at the ends and tails of the welds and ensuring the welding quality of the welds.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A steel plate automatic welding device includes a traveling device, a lifting device, and a laser gun. The traveling device is equipped with a lifting device, the lifting device is provided with a laser gun, the lifting device is provided with a drainage device with two drainage plates, the drainage device is used to drive the two drainage plates to respectively fit the edges of the steel plates on both sides, and the lifting device is provided with a cleaning piece, which is used to clean the residual solder on the drainage plates.

[0008] The drainage device is arranged to make the drainage plate adhere to the two sides of the steel plate, so that in the welding process, the drainage plate can adsorb the hot melting filler on the drainage plate through the surface tension of the liquid, guide the filler to the two sides of the steel plate weld through the drainage plate, and then make the filler more easily enter the steel plate weld, so as to ensure the filler on the two sides of the steel plate weld, thereby ensuring the welding quality of the weld, and the cleaning piece can clean the residual filler on the drainage plate, avoid the filler from caking to affect the adhesion of the drainage plate to the steel plate and affect the drainage effect, and thus ensure the welding quality of the steel plate.

[0009] Preferably, the drainage device comprises a mounting seat and a swing rod, the mounting seat is mounted on the lifting device, two swing rods are rotatably mounted on the mounting seat, the swing rod is a telescopic rod with a spring inside, two guide rails are formed in the mounting seat, square-shaped sliding blocks are slidably mounted in the guide rails, rotating shafts are mounted on the sliding blocks, the swing rods are rotatably connected with the rotating shafts, the drainage plates are fixedly connected with the sliding blocks, the guide rails are divided into vertical portions, inclined portions and flat portions, the flat portions are respectively communicated with the vertical portions and the inclined portions, the inclined portions are communicated with each other at one end away from the flat portions, torsion springs are connected between the swing rods and the mounting seat, and driving pieces are arranged on the mounting seat and connected with the swing rods.

[0010] The driving pieces and the swing rods can swing in the guide rails to control the up-down movement and horizontal movement of the two drainage plates, so that the drainage plates can contact the end of the steel plate weld, and thus the drainage can be performed by the drainage plates, while at the tail of the weld, the drainage can be performed by the drainage plate on the other side, and the torsion springs and the telescopic rods with springs inside can make the drainage plates move transversely and press the steel plate when the drainage plates move to the flat portions, so that the drainage plates can still adhere to the steel plate during the movement of the travelling device, thereby ensuring the continuity of the operation of the equipment, which not only ensures the operation efficiency of the equipment, but also ensures the one-time forming of the weld and the welding quality.

[0011] Preferably, the drainage plate is provided with an inner concave arc surface, the width of the inner concave arc surface is less than the thickness of the steel plate, a memory alloy piece is arranged inside the inner concave arc surface, and the memory alloy piece expands when heated.

[0012] The inner concave arc surface is arranged, and the width of the inner concave arc surface is less than the thickness of the steel plate, so that a closed space is formed between the inner concave arc surface and the steel plate, and thus more filler can be accommodated, and the memory alloy piece is arranged to expand and press the filler inside the closed space into the weld, thereby improving the filling effect of the weld and further ensuring the welding quality of the weld.

[0013] Preferably, the cleaning component includes a cleaning chamber opened on the mounting seat, an opening is provided on the cleaning chamber, the opening cooperates with the guide plate, a nozzle facing the opening is provided above the cleaning chamber, an air supply device is connected to the nozzle, an electromagnetic heating coil is provided inside the cleaning chamber, a discharge port is provided below the cleaning chamber, and a cleaning rail is provided at the connection between the vertical portion and the inclined portion.

[0014] By setting up the electromagnetic heating coil, the solder on the drain plate can be melted, and by jetting air through the nozzle, the solder on the drain plate can be cleaned, thereby avoiding solder residue and preventing the residual solder from being contaminated and affecting the quality of the weld. By cleaning the drain plate with gas, the cooling speed of the memory alloy sheet can be accelerated, and the memory alloy sheet can be quickly contracted, so that the memory alloy sheet can quickly enter the working state, thereby ensuring the working efficiency of the equipment.

[0015] Preferably, the straight portion of the guide rail located behind the first direction is inclined along a direction perpendicular to the first direction, and the projected length along the direction perpendicular to the first direction is greater than half the width of the guide plate. A transverse portion is connected between the straight portion and the inclined portion of the guide rail located in front of the first direction, and the transverse portion is inclined along a direction perpendicular to the first direction, and the projected length of the transverse portion along the direction perpendicular to the first direction is greater than half the width of the guide plate.

[0016] By tilting the straight portion along the first direction and projecting the length of the straight portion along the perpendicular first direction greater than half the width of the guide plate, the guide plate can move a distance greater than half the width of the guide plate along the perpendicular first direction when the straight portion of the guide plate behind the first direction slides, thereby causing the guide plate to separate from the weld in the direction of shear, thereby avoiding the problem that when the guide plate moves along the first direction and separates from the weld, the solder inside the weld is carried away due to the adsorption force of the guide plate, thereby causing the solder inside the weld to be missing and the quality of the weld to be reduced. When the guide plate moves when it is bonded to the steel plate, the vibration generated by the movement can improve the flow effect of the solder, making it easier for the solder to enter the weld, further ensuring the welding quality of the weld. The setting of the horizontal portion can also enable the guide plate located in front of the first direction to move along the direction perpendicular to the first direction when it moves along the vertical portion, thereby also ensuring the quality of the weld.

[0017] Preferably, the side and top of the opening are provided with a slope 1, a step is provided below the opening, the step is inclined upward, and an inclined shape is provided below the cleaning chamber. The slope 1 above the opening is parallel to the step, and the height of the slope 1 from the step in the vertical direction is equal to the height of the guide plate, the cleaning rail is parallel to the slope 1, and the slider is provided with a chamfer that cooperates with the cleaning rail.

[0018] The setting of the steps can prevent the hot-melt solder inside the cleaning chamber from flowing out, thereby preventing the flowing solder from adhering to the normal operation of the equipment on the guide rail. The inclined surface above the opening is parallel to the steps, and the vertical distance is equal to the height of the guide plate, so that the side edges of the guide plate can fit with the opening, thereby preventing the airflow from flowing out from the edge of the guide plate, causing the hot-melt solder to splash onto the guide rail and affect the movement of the guide plate. The guide plate is fully fitted with the opening, which can increase the pressure inside the cleaning chamber, so that the hot-melt solder can be quickly discharged through pressure, thereby preventing the hot-melt solder from solidifying and clogging the discharge port.

[0019] Preferably, the upper and side edges of the guide plate on one side of the cleaning chamber are provided with beveled chamfers, and mutually connected bevels 2 and 3 are provided below the guide plate, and the beveled chamfer 1 and the beveled chamfer 3 are located on the same side of the guide plate, and the multiple beveled chamfers are respectively parallel to the multiple beveled chamfers 1, and the beveled chamfer 2 is parallel to the step, and the beveled chamfer 2 extends to the bottom of the beveled chamfer, and the inclination angle of the beveled chamfer 3 is smaller than the inclination angle of the step.

[0020] By setting an oblique chamfer parallel to the first bevel, the contact area between the side, top and opening of the guide plate can be increased, and the setting of the second bevel parallel to the step can increase the contact area between the bottom of the guide plate and the opening, improve the sealing effect at the opening, and further prevent the airflow from flowing out of the edge of the guide plate, causing the hot melt solder to splash onto the guide rail and affect the movement of the guide plate. The second bevel extends to the bottom of the oblique chamfer, so that the sealing surfaces of the side, top and bottom are all in the same vertical direction, thereby avoiding gas leakage. The setting of the third bevel, and the inclination angle of the third bevel is smaller than the inclination angle of the step, so that when the second bevel is in contact with the step, there is a certain gap between the third bevel and the step, thereby avoiding the hot melt solder residue, which causes the guide plate to be unable to move after the solder solidifies.

[0021] Preferably, the rocker arm is divided into a movable part and a fixed part, the movable part is slidingly and sealingly connected to the fixed part, an exhaust hole is provided on the fixed part, and the movable part is rotatably connected to the rotating shaft.

[0022] The movable part of the rocker arm is slidingly and sealingly connected to the fixed part, and an exhaust hole is provided on the sliding part. Therefore, when the guide plate is popped out by the spring force, the air outlet of the exhaust hole can be set to slow down the extension and retraction speed of the movable rod, thereby avoiding the guide plate from popping out quickly and hitting the steel plate, causing large vibration of the steel plate, and avoiding the instability of the molten pool formed by the vibrating solder, thereby avoiding incomplete penetration of the weld or air entering the weld, thereby ensuring the welding quality.

[0023] Preferably, the length of the chamfer is greater than the length of the first inclined surface, and when the chamfer is in contact with the first inclined surface, both sides of the chamfer protrude from the first inclined surface.

[0024] By having the chamfer protrude from the bevel one on both sides when the chamfer fits with the bevel one, the chamfer can be squeezed against the bevel one during the movement of the drain plate, thereby effectively improving the sealing between the drain plate and the opening and preventing overflow of residual solder. The inner side of the drain plate protrudes from the bevel one, so that the width of the drain plate edge is smaller than the minimum width of the opening, so that the drain plate edge will not contact the bevel one during movement, thereby preventing the solder on the drain plate from adhering to the bevel one, which may easily cause the drain plate to adhere to the mounting base and become unable to move.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] 1. Through the setting of the drainage device, the drainage plate is attached to both sides of the steel plate. In this way, during the welding process, the hot melt solder can be adsorbed onto the drainage plate by the adsorption force of the drainage plate, and then the solder is guided to both sides of the steel plate weld through the drainage plate, making it easier for the solder to enter the steel plate weld, thereby ensuring the filling effect of the solder on both sides of the steel plate weld, thereby ensuring the welding quality of the weld. After welding is completed, the residual solder on the drainage plate is cleaned by the cleaning piece to ensure the sustainable operation of the equipment.

[0027] 2. By setting a step under the opening, the internal solder can be prevented from flowing out to the guide rail and solidifying, thereby affecting the movement of the guide plate. The setting of the chamfer and the second bevel of the guide plate can ensure the sealing between the guide plate and the opening, prevent the air flow from flowing out from the edge of the guide plate, and further prevent the hot melt solder from splashing onto the guide rail and affecting the movement of the guide plate.

[0028] 3. During the drainage process, the drainage device sets an inclined straight portion and an inclined horizontal portion inside the two guide rails, so that the drainage plate can move laterally during the drainage process, and then the drainage plate can be separated from the weld in the direction of shear, so as to avoid the problem that when the drainage plate moves along the weld direction and separates from the weld, the solder inside the weld is carried away due to the adsorption force of the drainage plate, thereby resulting in the loss of solder inside the weld and the deterioration of the weld quality. When the drainage plate is attached to the steel plate, it moves laterally, and the vibration generated by the movement can improve the flow effect of the solder, making it easier for the solder to enter the weld, further ensuring the welding quality of the weld.

[0037] See also Figures 1 to 7 The present invention provides a steel plate automatic welding equipment, the technical solution is as follows:

[0038] A steel plate automatic welding equipment, reference Figure 1 、 Figure 2 、 Figure 4 、 Figure 6 、 Figure 7, including a traveling device 1 and a lifting device 2, the traveling device 1 is electrically driven, the lifting device 2 is driven by a cylinder, and a laser gun 3 is installed on the lifting device 2; when in use, the lifting device 2 drives the laser gun 3 to move downward, so that the laser gun 3 is 6 mm away from the steel plate 13, at this time, the laser gun 3 is turned on to heat-melt the solder, so that the solder melts and penetrates into the weld, and then the traveling device 1 drives the laser gun 3 to move horizontally, so that the solder of the weld can be completely hot-melted, thereby completing the welding of the steel plate 13; a drainage device 4 is provided on the lifting device 2, and the drainage device 4 includes a mounting seat 42 provided on the lifting device 2, and a rocker arm 43 is rotatably installed on the mounting seat 42, and both ends of the rocker arm 43 are telescopic rods with built-in springs, and two guide rails 44 are provided on the mounting seat 42, A square-shaped slider 45 is slidably installed inside the guide rail 44, and a rotating shaft 46 is installed on the slider 45. The movable end of the rocker arm 43 is rotatably connected to the rotating shaft 46, and the guide plate 41 is fixedly connected to the slider 45. The guide rail 44 is divided into a vertical portion 441, an inclined portion 442 and a straight portion 443. The two ends of the straight portion 443 are respectively connected to the vertical portion 441 and the inclined portion 442, and the inclined portion 442 is connected to the end of the vertical portion 441 that is not connected to the straight portion 443. A torsion spring is connected between the rocker arm 43 and the mounting seat 42, and a driving member is provided on the mounting seat 42. The driving member is connected to the rocker arm 43. The driving member adopts a motor. Of course, the driving member can also adopt other power components, as long as it can drive the rocker arm 43 to rotate. A chamfer that matches the inclined portion 442 is provided on the slider 45;When welding, the driving member drives the rocker arm 43 at the rear of the traveling device 1 to rotate, so that the guide plate 41 on this side moves along the inclined portion 442 to the straight portion 443 under the guidance of the guide rail 44, and then moves along the straight portion 443 to fit the side of the weld of the steel plate 13. When welding, the guide plate 41 absorbs the solder on the weld and drains the solder downward through the guide plate 41, thereby filling the gap at the end of the weld. As the traveling device 1 moves, the torsion spring is compressed. When the guide plate 41 moves along the straight portion 443 to the inclined portion 442, the driving member drives the rocker arm 43 to swing upward. At this time, the rocker arm 43 contracts to make the slider 45 enter the inclined portion 442. , so that the drainage moves upward along the inclined portion 442 and separates from the side wall of the steel plate 13, and finally enters the uppermost portion of the inclined portion 442, thereby preventing the drainage plate 41 from interfering with the welding of the steel plate 13. When the driving device 1 drives the laser gun 3 to move to the end of the weld, the driving device 1 moves the front swing rod 43 to rotate, so that the side drainage plate 41 moves downward along the inclined portion 442. When the drainage plate 41 moves to the straight portion 443, the driving device continues to drive the drainage plate 41 to move horizontally along the straight portion 443 until the drainage plate 41 is in contact with the side wall of the steel plate 13 and the torsion spring is compressed. The driving device stops working, and as the driving device 1 moves, the swing rod 43 is driven by the force of the torsion spring. The slider 45 is pushed to move toward the side of the steel plate 13 so that the guide plate 41 is always in contact with the steel plate 13, thereby performing the drainage operation and ensuring the quality of the end of the weld. When the guide plate 41 moves to the vertical portion 441, the laser gun 3 moves to the end of the weld, and the slider 45 moves to the vertical portion 441. At this time, the driving member drives the rocker 43 to swing toward the vertical portion 441, which can squeeze the rocker 43 to contract and move the slider 45 to the top of the vertical portion 441, so that the guide plate 41 is separated from the steel plate 13 and ready for the next welding operation. The device can make the guide plate 41 move horizontally to squeeze the steel plate 13, so that the guide plate 41 can still be in contact with the steel plate 13 during the movement of the driving device 1. The plate 13 remains in a fitted state, thereby ensuring the continuity of the equipment operation, which not only ensures the operating efficiency of the equipment, but also ensures that the weld is formed in one go and the welding quality is guaranteed; the straight portion 443 of the guide rail 44 located at the rear of the first direction is inclined along the first direction perpendicular to the first direction, and the projected length along the first direction perpendicular to the first direction is greater than half the width of the guide plate 41, and a transverse portion 444 is connected between the straight portion 443 and the inclined portion 442 of the guide rail 44 located at the front of the first direction. The transverse portion 444 is inclined along the first direction perpendicular to the first direction, and the projected length of the transverse portion 444 perpendicular to the first direction is greater than half the width of the guide plate 41. The first direction is the moving direction of the traveling device 1, which is indicated by s in the figure;When the drainage plate 41 moves along the inclined flat portion 443, because the flat portion 443 is arranged along the first direction, the drainage plate 41 moves transversely during the movement, and when the drainage plate 41 moves along the transverse portion 444, because the transverse portion 444 is arranged along the first direction, the drainage plate 41 also moves transversely during the movement, and when the drainage plate 41 is attached to the steel plate 13, the vibration generated by the movement can improve the flow effect of the solder, so that the solder can more easily enter the weld, further ensuring the welding quality of the weld, and the projection length of the inclined flat portion 443 and the transverse portion 444 along the first direction is greater than half the width of the drainage plate 41 by 5 mm, so that when the drainage plate 41 moves transversely, the drainage plate 41 moves transversely away from the weld, so that the drainage plate 41 moves away from the weld in the shearing direction, thereby avoiding the problem that when the drainage plate 41 moves along the first direction, the solder in the weld is taken away due to the adsorption force of the drainage plate 41, thereby causing the solder in the weld to be missing and causing the quality of the weld to decrease; the drainage plate 41 is provided with an inner concave arc surface 6, the width of the inner concave arc surface 6 is less than the thickness of the steel plate 13, and the inner concave arc surface 6 is provided with a memory alloy piece 7, the memory alloy piece 7 expands when heated, and the memory alloy transformation temperature is 120°C; the inner concave arc surface 6 is provided, and the width of the inner concave arc surface 6 is less than the thickness of the steel plate 13, so that a closed space is formed between the inner concave arc surface 6 and the steel plate 13, and therefore more solder can be accommodated, and the memory alloy piece 7 is provided, so that when the solder contacts the memory alloy piece 7, the temperature of the memory alloy piece 7 is higher than 120°C, so that the memory alloy piece 7 expands and squeezes the solder in the closed space into the weld, thereby improving the filling effect of the weld and further ensuring the welding quality of the weld; the swing rod 43 is divided into a movable portion 431 and a fixed portion 432, the movable portion 431 and the fixed portion 432 are in sliding sealing connection, the fixed portion 432 is provided with an exhaust hole 433, and the movable portion 431 is in rotational connection with the rotating shaft 46; the movable portion 431 and the fixed portion 432 of the swing rod 43 are in sliding sealing connection, and the exhaust hole 433 is arranged on the sliding portion, so that when the drainage plate 41 is ejected by the spring force, the exhaust amount can be controlled through the exhaust hole 433, thereby slowing down the extension and retraction speed of the movable rod, so as to avoid the drainage plate 41 from being ejected quickly and hitting the steel plate 13 or the drainage plate 41 from being extended and retracted quickly to cause vibration, which can not only avoid the solder from splashing due to the vibration of the drainage plate 41, but also avoid the molten pool formed by the solder from being unstable, thereby avoiding the problem of incomplete penetration of the weld or air entering the weld, and thus ensuring the welding quality.

[0039] REFERENCE Figures 1 to 6, a cleaning member 5 is provided inside the mounting seat 42, and the cleaning member 5 includes two cleaning chambers 51 opened on the mounting seat 42, and the two cleaning chambers 51 are respectively located on one side of the two vertical parts 441, and an opening 52 is provided on the cleaning chamber 51, and the opening 52 cooperates with the guide plate 41. A nozzle 53 facing the opening 52 is provided above the cleaning chamber 51, and an air supply device is connected to the nozzle 53. The air supply device is a compressed air system that can provide high-speed gas to the nozzle 53. An electromagnetic heating coil 54 is provided inside the cleaning chamber 51, and a discharge port 55 is provided below the cleaning chamber 51. A cleaning rail 56 is provided at the connection between the vertical part 441 and the inclined part 442; when the slider 45 moves to the uppermost part of the vertical part 441, the driving The component drives the rocker rod 43 to move to the side of the cleaning rail 56. At this time, the slider 45 can drive the guide plate 41 to move to the side of the cleaning chamber 51. Then, the electromagnetic heating coil 54 is set to melt the solder on the guide plate 41, and the nozzle 53 is sprayed with air to clean the solder on the guide plate 41 by blowing the air flow, thereby avoiding solder residue, thereby avoiding the residual solder from being contaminated and affecting the quality of the weld. By cleaning the guide plate 41 with gas, the cooling speed of the memory alloy sheet 7 can be accelerated, so that the memory alloy sheet 7 can shrink quickly, so that the memory alloy sheet 7 can quickly enter the working state, thereby ensuring the working efficiency of the equipment; the side and top of the opening 52 are provided with a bevel 8, and the bottom of the opening 52 is provided with a bevel 8. There is a step 9, which is inclined upward. The cleaning chamber 51 is provided with an inclined shape below. The inclined surface 8 above the opening 52 is parallel to the step 9, and the vertical distance between the inclined surface 8 and the step 9 is equal to the height of the guide plate 41. The cleaning rail 56 is parallel to the inclined surface 8, and the slider 45 is provided with a chamfer that matches the cleaning rail 56. The setting of the step 9 can prevent the hot melt solder inside the cleaning chamber 51 from flowing out, thereby preventing the outflowing solder from adhering to the guide rail 44 and the normal operation of the equipment. The inclined surface 8 above the opening 52 is parallel to the step 9, and the vertical distance is equal to the height of the guide plate 41, so that the sides of the guide plate 41 can fit with the opening 52, thereby preventing the airflow from flowing out of the edge of the guide plate 41, causing heat to accumulate. The molten solder splashes onto the guide rail 44 and affects the movement of the guide plate 41. The guide plate 41 is completely fitted with the opening 52, which can increase the internal pressure of the clean chamber 51, so that the hot-melt solder can be quickly discharged by pressure, thereby preventing the hot-melt solder from solidifying and clogging the discharge port 55. The guide plate 41 is located on one side of the clean chamber 51. The upper and side edges are provided with chamfers 10. The lower side of the guide plate 41 is provided with a second chamfer 11 and a third chamfer 12 connected to each other. The third chamfer 12 and the chamfer 10 are located on the same side of the guide plate 41. The multiple chamfers 10 are respectively parallel to the multiple first chamfers 8. The second chamfer 11 is parallel to the step 9, and the second chamfer 11 extends to the bottom of the chamfer 10. The inclination angle of the third chamfer 12 is smaller than the inclination angle of the step 9.By setting an oblique chamfer 10 parallel to the inclined surface 1 8, the contact area between the side, top and opening 52 of the guide plate 41 can be increased, and the setting of the inclined surface 2 11 parallel to the step 9 can increase the contact area between the bottom of the guide plate 41 and the opening 52, improve the sealing effect at the opening 52, and further prevent the airflow from flowing out of the edge of the guide plate 41, causing the hot melt solder to splash onto the guide rail 44 and affect the movement of the guide plate 41. The inclined surface 2 11 extends below the oblique chamfer 10, so that the sealing surfaces of the side, top and bottom are all in the same vertical direction, thereby avoiding gas leakage. The setting of the inclined surface 3 12, and the inclination angle of the inclined surface 3 12 is smaller than the inclination angle of the step 9, so that when the inclined surface 2 11 is in contact with the step 9, there is a certain gap between the inclined surface 3 12 and the step 9, thereby avoiding the hot melt solder residue and the solder solidification. The problem of the guide plate 41 being unable to move after the deformation is solved; the length of the chamfer 10 is greater than the length of the bevel 8, and when the chamfer 10 and the bevel 8 are in contact, both sides of the chamfer 10 protrude from the bevel 8; by having both sides of the chamfer 10 protrude from the bevel 8 when the chamfer 10 and the bevel 8 are in contact, the chamfer 10 can be pressed against the bevel 8 during the movement of the guide plate 41, thereby effectively improving the sealing between the guide plate 41 and the opening 52 and preventing the overflow of residual solder. The inner side of the guide plate 41 protrudes from the bevel 8, so that the width of the edge of the guide plate 41 is smaller than the minimum width of the opening 52, so that the edge of the guide plate 41 will not contact the bevel 8 during the movement, thereby preventing the solder on the guide plate 41 from adhering to the bevel 8, which can easily cause the guide plate 41 to adhere to the mounting seat 42 and become unable to move.

[0040] Working principle: Reference Figures 1 to 7, when welding, solder is applied on the weld seam by a paste dispenser. After the solder coating is completed, the lifting device 2 and the laser gun 3 are started. At this time, the lifting device 2 pushes the laser gun 3 to move so that the laser gun 3 is 6 mm away from the surface of the steel plate 13. During the downward movement of the lifting device 2, the driving part is started to swing the rocker 43 located behind the first direction. At this time, the slider 45 moves along the inclined portion 442 to the straight portion 443, and then moves along the straight portion 443 until it is in contact with the steel plate 13. At this time, the laser gun 3 can be started to perform the welding operation. The guide plate 41 can now drain the hot melt solder. After the welding starts, the welding seam of the traveling device 1 moves at a uniform speed. At this time, the steel plate 13 squeezes the guide plate 41, and at this time, the slider 45 moves along the straight portion 443. The straight portion 443 of the side guide rail 44 is tilted perpendicular to the first direction, so that the slider When the block 45 moves along the straight portion 443, it drives the guide plate 41 to move laterally in a direction perpendicular to the first direction and squeezes the torsion spring so that the guide plate 41 always fits the steel plate 13. As the traveling device 1 moves, the guide plate 41 is squeezed and moves to the connection between the inclined portion 442 and the straight portion 443. At this time, the guide plate 41 moves laterally and disengages from the weld. At this time, the driving member is started, causing the rocker arm 43 to swing toward the inclined portion 442, thereby causing the rocker arm 43 to move obliquely upward, thereby disengaging from the steel plate 13, and thus will not interfere with the movement of the traveling device 1. When the slider 45 moves to the top of the inclined portion 442, the driving member continues to drive the rocker arm 43 to rotate, causing the slider 45 to move along the cleaning rail, so that when the guide plate 41 moves to the opening 52, it moves obliquely downward along the inclined surface 8, so that the guide plate 41 completely closes the opening 52, and the driving member stops.

[0041] When the laser gun 3 is 10 cm away from the end of the weld, the driving part is started again, and the rocker 43 in the first direction is driven to swing along the inclined portion 442. At this time, the slider 45 moves along the inclined portion 442 to the straight portion 443, and moves along the straight portion 443 to fit the steel plate 13. At this time, the driving part continues to rotate, so that the torsion spring is compressed. As the driving device 1 moves, the torsion spring pushes the rocker 43 to swing, so that the guide plate 41 always fits the steel plate 13. When the laser gun 3 moves to the end of the weld of the steel plate 13, the guide plate 41 can drain the solder to fill the gap at the end of the weld. When the solder is hot-melted, it stays still for 3 seconds, and then the driving part is started, driving the rocker 43 to move toward the vertical portion 441, and then the slider 45 enters the horizontal portion 444, so that when the guide plate 41 moves upward, the guide plate 41 moves in a direction perpendicular to the weld, so that the guide plate 41 laterally separates from the steel plate 13, and moves vertically to above the vertical part 441 after separating from the steel plate 13. When the rocker arm 43 moves to the uppermost part of the vertical part 441, the driving part drives the rocker arm 43 to rotate in the direction of the rocker arm 43, so that the slider 45 moves along the cleaning rail 56, thereby making the guide plate 41 on this side close the opening 52, and then the lifting device 2 contracts, and the driving device 1 drives the laser gun 3 to reset. In the process again, the two guide plates 41 cooperate with the openings 52 on both sides of the cleaning chamber 51. At this time, the electromagnetic heating coil 54 is turned on for heating for 10s, and at 5s, the air supply device provides compressed air to the nozzle 53 to clean the surface of the guide plate 41. After the electromagnetic heating coil 54 stops heating, the air supply device provides compressed air to the nozzle 53 for 15s to cool the extruded alloy sheet. At this time, the guide plate 41 can be cleaned, so that the welding equipment is ready to take over the operation next time.
