Description

Technical Field

[0001] The present invention relates to the technical field of laser welding positioning, and specifically relates to a laser welding machine tool for mechanical processing. Background Technique

[0002] A laser welding positioning device generally refers to a device that ensures the stability of an object during the laser welding process to guarantee the welding accuracy. In the traditional laser welding process, the object cannot be stably fixed and clamped, resulting in the inability to guarantee the stability and accuracy during welding.

[0003] The patent with the patent announcement number CN215747223U discloses a laser welding machine tool for mechanical processing. A connecting support column is installed at the lower end of the water storage tank, and four connecting support columns are provided. An anti-slip rubber base is installed at the lower end of the connecting support column, and four anti-slip rubber bases are provided. A positioning box body is installed at the upper end of the water storage tank. A water injection protrusion is installed on one side of the positioning box body. A water injection port is installed at the upper end of the water injection protrusion. A baffle is installed at the upper end of the positioning box body, and two baffles are provided. A transmission gear is installed on one side of the positioning box body. A stepping motor is installed at the lower end of the transmission gear. A telescopic fixing column is installed on the inner wall of the positioning box body. A four-jaw centering column is installed at one end of the telescopic fixing column. This patent avoids the problems that the existing laser welding positioning device cannot adjust the angle for multi-faceted processing of parts during operation, and the irritating odor generated during welding overflows, causing air pollution.

[0004] However, this device still has deficiencies: Although this device can adjust the angle for multi-faceted processing of parts, for the orientation calibration between the workpiece and the welding head, it needs to be manually adjusted by the staff, which extends the positioning time before welding the workpiece to a certain extent, and is likely to cause the positioning accuracy between the welding part of the workpiece and the welding head to decrease, resulting in poor welding quality. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides a laser welding machine tool for mechanical processing, which solves the problems raised in the above background technique.

[0006] To achieve the above object, the present invention is realized through the following technical solutions: A laser welding machine tool for machining, including a cabinet, a welding mechanism is provided on the top of the cabinet, an air flow groove is provided inside the welding mechanism, drive components are provided at both ends of the welding mechanism, a drying mechanism is provided at the bottom edge of the inner wall of the cabinet, and desiccant particles are built in the drying mechanism. An electric telescopic rod is fixedly installed on one side of the drive component close to the cabinet, and a chute plate is fixedly installed on one side of the telescopic end of the electric telescopic rod close to the center of the welding mechanism. A smoke-proof device for absorbing welding fumes is arranged around the chute plate, and an anti-interference device for ensuring a constant humidity inside the welding mechanism is arranged below the smoke-proof device. A number of trapezoidal clips are symmetrically and slidably installed inside the chute plate. A number of rubber rollers are rotatably installed on one side of the trapezoidal clip close to the center of the chute plate. A U-shaped shovel frame is fixedly installed on one side of the bottom end of the chute plate close to the trapezoidal clip. A number of cross bars are fixedly installed at equal intervals inside the U-shaped shovel frame, and elastic telescopic plates are penetrated and rotatably installed on the outer walls of the cross bars.

[0007] The electric push rod is provided at the bottom of the inner wall of the cabinet, and a workbench is fixedly installed on the top of the telescopic end of the electric push rod, and the workbench is located inside the welding mechanism, and the drying mechanism is located below the air flow slot, and the electric telescopic rod is located inside the welding mechanism. Springs are provided between the trapezoidal clamps and the slide plate, and the bottom of the U-shaped shovel frame contacts the top of the workbench, and the interior of the elastic telescopic plate and the cross bar are provided with torsion springs for resetting the elastic telescopic plate. The workpiece is placed on the top of the workbench, and the electric telescopic rod is started. The telescopic end of the electric telescopic rod drives the slide plate to move toward the center direction of the welding mechanism, and the slide plate drives the trapezoidal clamp to move synchronously. As the trapezoidal clamp gradually approaches the workpiece, the inclined surface of the trapezoidal clamp contacts the outer wall of the workpiece to generate a resistance force, and the trapezoidal clamps at both ends generate a resistance force when they are subjected to force synchronously. With the help of the continuous extension of the telescopic end of the electric telescopic rod, the trapezoidal clamp is prompted to slide along the inside of the slide plate toward the direction away from the center of the welding mechanism, and the spring elastic force between the trapezoidal clamp and the slide plate is relied on to cause the trapezoidal clamp to apply an extruding clamping force to the workpiece during the horizontal sliding process, and the trapezoidal clamp drives The rubber roller moves synchronously, and friction is generated when the rubber roller contacts the outer wall of the workpiece. At this time, the rubber roller rotates inside the trapezoidal clamp. During the rotation of the rubber roller, the trapezoidal clamp is convenient for clamping the workpiece, and the friction between the trapezoidal clamp and the workpiece is increased by relying on the rubber characteristics. After clamping is completed, the electric push rod is started, and the telescopic end of the electric push rod drives the workbench to retract downward. When the driving component drives the electric telescopic rod to rotate, the workpiece rotates synchronously; when the slide plate moves toward the center of the welding mechanism, it drives the U-shaped shovel frame to move synchronously. The U-shaped shovel frame slides along the top of the workbench and shovels at the bottom of the workpiece through its own inclined surface. Relying on the shoveling and guiding of the U-shaped shovel frame, the workpiece is caused to move slightly upward. At this time, the friction between the workpiece and the outer wall of the rubber roller increases, and the U-shaped shovel frame drives the cross bar to move synchronously during the horizontal movement. The cross bar drives the elastic telescopic plate to move synchronously. The telescopic end of the elastic telescopic plate is higher than the top of the U-shaped shovel frame. When the telescopic end of the elastic telescopic plate contacts the bottom of the workpiece, a resistance force is generated. At this time, the elastic telescopic plate rotates along the outer wall of the cross bar, and its own telescopic end will be close to the bottom of the workpiece as the workpiece is pressed and slid.

[0008] According to the above technical solution, the anti-smoke device includes a gear, the interior of the gear passes through and is fixedly installed on the outer wall of the fixed end of the electric telescopic rod, a transmission wheel is rotatably installed on the inner wall of the welding mechanism, a reciprocating screw is fixedly installed inside the transmission wheel, and a smoke exhaust component is passed through and movably installed on the outer wall of the reciprocating screw.

[0009] According to the above technical solution, the transmission wheel is meshed with the gear, and the smoke exhaust component is slidably installed on the inner wall of the welding mechanism away from the gear. When the electric telescopic rod rotates, it drives the gear to rotate, and the gear drives the transmission wheel to rotate along the inner wall of the welding mechanism. The transmission wheel drives the reciprocating screw to rotate. When the reciprocating screw rotates, it drives the smoke exhaust component installed on the inner wall of the welding mechanism to slide horizontally and reset through the non-self-locking spiral groove on its outer wall.

[0010] According to the above technical solution, a transmission plate is hinged to one side of the smoke exhaust assembly close to the center of the welding mechanism through a torsion spring. An activated carbon plate is slidably installed at the bottom of the transmission plate. A humidity sensor is hinged to one end of the transmission plate close to the center of the welding mechanism. The humidity sensor is slidably installed on the inner wall of the welding mechanism on the side away from the reciprocating lead screw. When the smoke exhaust assembly moves horizontally, it drives the transmission plate to move synchronously. During the movement of the transmission plate, it is limited by the humidity sensor. At this time, the hinge shaft of the transmission plate starts to rotate. The transmission plate uses the hinge shaft as the axis to cause the humidity sensor to slide downward along the inner wall of the welding mechanism. At this time, the transmission plate drives the activated carbon plate to move synchronously.

[0011] According to the above technical solution, the anti-interference device includes a plurality of inclined plates. The tops of the plurality of inclined plates are all hinged to the bottom of the humidity sensor. A sliding plate is hinged to the bottom of the inclined plate. A return frame is hinged to one side of the inclined plate close to the reciprocating lead screw through a torsion spring.

[0012] According to the above technical solution, a torsion spring is provided between the top of the inclined plate and the bottom of the humidity sensor. The bottom of the sliding plate contacts the bottom of the inner wall of the welding mechanism. The top of the return frame is hinged to the bottom of the activated carbon plate. When the humidity sensor moves downward along the inner wall of the welding mechanism, it drives the inclined plate to move synchronously. During the movement of the inclined plate, it is limited by the sliding plate. At this time, the hinge shaft of the inclined plate starts to rotate. The inclined plate uses the hinge shaft as the axis to push the sliding plate to slide horizontally along the bottom of the inner wall of the welding mechanism. The sliding plate drives the return frame to move synchronously. During this process, the transmission plate drives the activated carbon plate to gradually approach the return frame along an arc trajectory. The return frame pushes the activated carbon plate to move along the inclined surface of the transmission plate towards the smoke exhaust assembly.

[0013] According to the above technical solution, a hollow plate is fixedly installed at the bottom of the sliding plate. A U-shaped ladder is fixedly installed at the bottom of the hollow plate. The bottom of the U-shaped ladder contacts the bottom of the inner wall of the drying mechanism. I-shaped rollers are symmetrically and rotatably installed inside the U-shaped ladder. The outer walls at both ends of the I-shaped rollers contact the bottom of the inner wall of the drying mechanism. An angular plate is fixedly installed on one side of the I-shaped roller close to the axis of the U-shaped ladder. When the sliding plate slides horizontally, it drives the hollow plate to move synchronously. The hollow plate drives the U-shaped ladder to move horizontally inside the drying mechanism. The U-shaped ladder drives the I-shaped rollers to move synchronously. When the two ends of the I-shaped rollers contact the bottom of the inner wall of the drying mechanism, frictional force is generated. At this time, the I-shaped rollers start to rotate by the frictional force. When the I-shaped rollers rotate, they drive the angular plate to revolve. When the angular plate revolves, it flips the desiccant particles inside the drying mechanism. That is, the longer the welding time of the workpiece, the more frequent the flipping frequency of the angular plate to the desiccant particles, and the dry air flow is discharged into the welding mechanism through the air flow groove.

[0014] The present invention provides a laser welding machine tool for machining. It has the following beneficial effects: (1) The present invention realizes multi-directional adjustment welding of workpieces through the cooperation of an electric telescopic rod, a chute plate, a trapezoidal clamp, a rubber roller, a U-shaped shovel frame, a cross bar, and an elastic telescopic plate, optimizing the practicality of the equipment. At the same time, the trapezoidal clamp realizes automatic centering positioning and stable clamping of the workpiece, eliminating the need for manual adjustment of the workpiece orientation by the staff, simplifying the work process of the staff, improving the precise positioning between the welding position required by the workpiece and the welding head, and ensuring the welding quality. And relying on the pushing of the U-shaped shovel frame, the rubber roller can be closely attached to the outer wall of the workpiece, that is, enhancing the clamping strength of the trapezoidal clamp on the workpiece, and the elastic telescopic plate increases the supporting force of the U-shaped shovel frame on the bottom of the workpiece, avoiding the phenomenon of the workpiece falling when making a circular motion.

[0015] (2) Through the setting of the anti-smoke device, the present invention effectively expands the activity range of the smoke exhaust component through the cooperation of an electric telescopic rod, a gear, a transmission wheel, a reciprocating lead screw, a smoke exhaust component, a transmission plate, an activated carbon plate, and a humidity sensor. That is, when welding the workpiece, the smoke exhaust component will gradually move to the welding position of the workpiece, timely extracting the smoke generated during welding, avoiding the smoke from blocking the line of sight of the workpiece personnel and making it difficult to adjust the welding plan in a timely manner according to the actual welding situation. At the same time, it avoids the erosion of the weld by smoke particles and reduces the weld strength. And it effectively expands the monitoring range of the humidity sensor for the humidity inside the welding mechanism at the beginning of the welding work, improving the comprehensiveness of the humidity monitoring inside the welding mechanism, avoiding the increase in the probability of pores in the weld due to the imbalance of humidity control on the inner wall of the welding mechanism, and preventing the reduction of the welding quality of the equipment for the workpiece.

[0016] (3) Through the setting of the anti-interference device, the present invention promotes the activated carbon plate to be closer to the smoke gathering place through the cooperation of a humidity sensor, an inclined plate, a sliding plate, a return frame, a hollow plate, a U-shaped ladder frame, an I-shaped roller, and an angular plate, purifying the harmful or irritating substances in the smoke, improving the emission standard of welding smoke, avoiding the harm to the health of external staff caused by the direct emission of untreated smoke, and at the same time improving the environmental protection standard of the equipment. At the same time, relying on the dry gas to effectively dry the moisture generated inside the welding mechanism during the long-term welding process, and using the humidity sensor to strictly monitor the moisture inside the welding mechanism, avoiding the increase in the possibility of welding laser scattering due to the humidity index being greater than the constant index, and at the same time avoiding the damage of the welding components due to moisture erosion and reducing their own use accuracy.

A plurality of cross bars 12 are equidistantly and fixedly installed inside the U-shaped shovel frame 11. The outer walls of the plurality of cross bars 12 all penetrate and are rotatably installed with elastic telescopic plates 13.

[0021] An electric push rod 4 is provided at the bottom of the inner wall of the cabinet 1. The top of the telescopic end of the electric push rod 4 is fixedly installed with a workbench 5. The workbench 5 is located inside the welding mechanism 2. The drying mechanism 6 is located below the air flow groove. The electric telescopic rod 7 is located inside the welding mechanism 2. Springs are provided between several trapezoidal clamps 9 and the chute plate 8. The bottom of the U-shaped shovel frame 11 is in contact with the top of the workbench 5. A torsion spring for resetting the elastic telescopic plate 13 is provided between the inside of the elastic telescopic plate 13 and the cross bar 12. Through the above cooperation, multi-directional adjustment welding of the workpiece is realized, the practicability of the equipment is optimized. At the same time, the trapezoidal clamp 9 realizes automatic centering positioning and stable clamping of the workpiece, without the need for staff to manually adjust the orientation of the workpiece, simplifies the work process of the staff, improves the precise positioning between the welding position required by the workpiece and the welding head, and ensures the welding quality; through the above cooperation, relying on the pushing of the U-shaped shovel frame 11, the rubber roller 10 can be closely attached to the outer wall of the workpiece, that is, the clamping strength of the trapezoidal clamp 9 on the workpiece is enhanced, and the elastic telescopic plate 13 increases the supporting force of the U-shaped shovel frame 11 on the bottom of the workpiece, avoiding the phenomenon of the workpiece falling when making a circular motion.

[0022] When in use, place the workpiece on the top of the workbench 5, start the electric telescopic rod 7, the telescopic end of the electric telescopic rod 7 drives the slide plate 8 to move toward the center of the welding mechanism 2, and the slide plate 8 drives the trapezoidal clamp 9 to move synchronously. As the trapezoidal clamp 9 gradually approaches the workpiece, the inclined surface of the trapezoidal clamp 9 contacts the outer wall of the workpiece to generate a resistance force, and the trapezoidal clamps 9 at both ends are subjected to force synchronously to generate a resistance force. With the help of the continuous extension of the telescopic end of the electric telescopic rod 7, the trapezoidal clamp 9 is prompted to slide along the inside of the slide plate 8 away from the center of the welding mechanism 2, and the spring force between the trapezoidal clamp 9 and the slide plate 8 is relied on to prompt the trapezoidal clamp 9 to contact the workpiece during the horizontal sliding process. The extrusion clamping force is applied, and the trapezoidal clamp 9 drives the rubber roller 10 to move synchronously. When the rubber roller 10 contacts the outer wall of the workpiece, friction is generated. At this time, the rubber roller 10 rotates inside the trapezoidal clamp 9. During the rotation of the rubber roller 10, the trapezoidal clamp 9 is convenient for clamping the workpiece, and the friction between the trapezoidal clamp 9 and the workpiece is increased by relying on the rubber characteristics. After the clamping is completed, the electric push rod 4 is started, and the telescopic end of the electric push rod 4 drives the workbench 5 to retract downward. When the driving component 3 drives the electric telescopic rod 7 to rotate, the workpiece rotates synchronously. Through the above cooperation, the multi-directional adjustment welding of the workpiece is realized, the practicality of the equipment is optimized, and the trapezoidal clamp 9 is effective for the workpiece. The automatic centering positioning and stable clamping are now implemented, and the staff does not need to manually adjust the workpiece orientation, which simplifies the staff's work process, improves the precise positioning between the welding point and the welding head required for the workpiece, and ensures the welding quality; when the slide plate 8 moves toward the center direction of the welding mechanism 2, it drives the U-shaped shovel frame 11 to move synchronously, and the U-shaped shovel frame 11 slides along the top of the workbench 5 and shovels at the bottom of the workpiece through its own inclined surface. Relying on the shoveling and guiding of the U-shaped shovel frame 11, the workpiece is caused to move slightly upward. At this time, the friction between the workpiece and the outer wall of the rubber roller 10 increases, and the U-shaped shovel frame 11 drives the cross bar 12 synchronously during the horizontal movement The cross bar 12 drives the elastic telescopic plate 13 to move synchronously, and the telescopic end of the elastic telescopic plate 13 is higher than the top of the U-shaped shovel frame 11. When the telescopic end of the elastic telescopic plate 13 contacts the bottom of the workpiece, a resistance force is generated. At this time, the elastic telescopic plate 13 rotates along the outer wall of the cross bar 12, and its own telescopic end will be close to the bottom of the workpiece as the workpiece is pressed and slid by friction. Through the above cooperation, the U-shaped shovel frame 11 is pushed to enable the rubber roller 10 to be close to the outer wall of the workpiece, that is, the clamping strength of the trapezoidal clamp 9 on the workpiece is enhanced, and the elastic telescopic plate 13 increases the supporting strength of the U-shaped shovel frame 11 on the bottom of the workpiece to avoid the workpiece from falling when it makes a circular motion.

[0023] See also Figures 1 - 8 , based on the above embodiment, another embodiment of the present invention further includes a smoke prevention device 14; The smoke prevention device 14 includes a gear 141. The gear 141 is internally penetrated and fixedly installed on the outer wall of the fixed end of the electric telescopic rod 7. A transmission wheel 142 is rotatably installed on the inner wall of the welding mechanism 2. A reciprocating lead screw 143 is fixedly installed inside the transmission wheel 142. A smoke exhaust component 144 is penetrated and movably installed on the outer wall of the reciprocating lead screw 143.

[0024] The transmission wheel 142 meshes with the gear 141. The smoke exhaust component 144 is slidably installed on the inner wall of the welding mechanism 2 on the side away from the gear 141. Through the above cooperation, the movement range of the smoke exhaust component 144 is effectively expanded. That is, when welding a workpiece, the smoke exhaust component 144 will gradually move to the welding position of the workpiece, timely extract the smoke generated during welding, avoid the smoke blocking the sight of the workpiece and the operator, making it difficult to adjust the welding plan in time according to the actual welding situation, and at the same time avoid the smoke particles eroding the weld and reducing the weld strength.

[0025] A transmission plate 145 is hinged to the smoke exhaust component 144 on the side close to the center of the welding mechanism 2 through a torsion spring. An activated carbon plate 146 is slidably installed at the bottom of the transmission plate 145.

[0026] During use, when the electric telescopic rod 7 rotates, it drives the gear 141 to rotate. The gear 141 drives the transmission wheel 142 to rotate along the inner wall of the welding mechanism 2. The transmission wheel 142 drives the reciprocating lead screw 143 to rotate. When the reciprocating lead screw 143 rotates, it drives the smoke exhaust assembly 144 to slide horizontally along the inner wall of the welding mechanism 2 and reset through the non-self-locking spiral groove on its outer wall. Through the above cooperation, the activity range of the smoke exhaust assembly 144 is effectively expanded. That is, when welding a workpiece, the smoke exhaust assembly 144 will gradually move to the welding position of the workpiece, timely extract the smoke generated during welding, avoid the smoke from blocking the line of sight of the workpiece and the operator, making it difficult to adjust the welding plan in a timely manner according to the actual welding situation, and at the same time avoid the smoke particles from eroding the weld seam and reducing the weld strength. When the smoke exhaust assembly 144 moves horizontally, it drives the transmission plate 145 to move synchronously. During the movement of the transmission plate 145, it is limited by the humidity sensor 147. At this time, the hinge shaft of the transmission plate 145 starts to rotate, and the transmission plate 145 makes the humidity sensor 147 slide downward along the inner wall of the welding mechanism 2 with the hinge shaft as the axis. At this time, the transmission plate 145 drives the activated carbon plate 146 to move synchronously. Through the above cooperation, the monitoring range of the humidity inside the welding mechanism 2 by the humidity sensor 147 at the beginning of the welding operation is effectively expanded, improving the comprehensiveness of the humidity monitoring inside the welding mechanism 2, avoiding the increase in the probability of pores in the weld seam due to the imbalance of humidity control on the inner wall of the welding mechanism 2, and preventing the reduction of the welding quality of the equipment for the workpiece.

[0027] Please refer to Figures 1 - 8 , on the basis of the above embodiments, another embodiment of the present invention further includes an anti-interference device 15; The anti-interference device 15 includes a plurality of inclined plates 151. The tops of the plurality of inclined plates 151 are all hinged to the bottom of the humidity sensor 147. The bottom of the inclined plate 151 is hinged to a sliding plate 152. One side of the inclined plate 151 close to the reciprocating lead screw 143 is hinged to a return frame 153 through a torsion spring.

[0028] A torsion spring is provided between the top of the inclined plate 151 and the bottom of the humidity sensor 147. The bottom of the sliding plate 152 contacts the bottom of the inner wall of the welding mechanism 2. The top of the return frame 153 is hinged to the bottom of the activated carbon plate 146. Through the above cooperation, the activated carbon plate 146 is urged to be closer to the smoke gathering place, purify the harmful or irritating substances in the smoke, improve the emission standard of welding smoke, avoid the direct emission of untreated smoke from harming the health of external workers, and at the same time improve the environmental protection standard of the equipment.

[0029] A hollow plate 154 is fixedly installed at the bottom of the sliding plate 152. A U-shaped ladder 155 is fixedly installed at the bottom of the hollow plate 154. The bottom of the U-shaped ladder 155 is in contact with the bottom inner wall of the drying mechanism 6. The I-shaped rollers 156 are symmetrically and rotatably installed inside the U-shaped ladder 155. The outer walls at both ends of the I-shaped rollers 156 are in contact with the bottom inner wall of the drying mechanism 6. An angular plate 157 is fixedly installed on one side of the I-shaped roller 156 close to the axis of the U-shaped ladder 155. Through the above cooperation, the moisture generated inside the welding mechanism 2 during long-term welding is effectively dried by relying on the drying gas, and the moisture inside the welding mechanism 2 is rigorously monitored by means of the humidity sensor 147, so as to avoid the humidity index being greater than the constant index, thereby increasing the possibility of welding laser scattering, and at the same time avoiding damage to the welded parts due to moisture erosion, thus reducing their own use accuracy.

[0030] During use, when the humidity sensor 147 moves downward along the inner wall of the welding mechanism 2, it drives the inclined plate 151 to move synchronously. During the movement of the inclined plate 151, it is limited by the sliding plate 152. At this time, the hinge shaft of the inclined plate 151 starts to rotate. The inclined plate 151 pushes the sliding plate 152 to slide horizontally along the bottom inner wall of the welding mechanism 2 with the hinge shaft as the axis. The sliding plate 152 drives the loop frame 153 to move synchronously. During this process, the transmission plate 145 drives the activated carbon plate 146 to gradually approach the loop frame 153 along an arc trajectory. The loop frame 153 pushes the activated carbon plate 146 to move along the inclined surface of the transmission plate 145 towards the smoke exhaust assembly 144. Through the above cooperation, the activated carbon plate 146 is made to be closer to the smoke gathering place, purifying the harmful or irritating substances in the smoke, improving the emission standard of welding smoke, avoiding the harm to the health of external workers caused by the direct emission of untreated smoke, and at the same time improving the environmental protection standard of the equipment; when the sliding plate 152 slides horizontally, it drives the hollow plate 154 to move synchronously. The hollow plate 154 drives the U-shaped ladder 155 to move horizontally inside the drying mechanism 6. The U-shaped ladder 155 drives the I-shaped rollers 156 to move synchronously. When the two ends of the I-shaped rollers 156 are in contact with the bottom inner wall of the drying mechanism 6, friction is generated. At this time, the I-shaped rollers 156 start to rotate by friction. When the I-shaped rollers 156 rotate, they drive the angular plate 157 to revolve. When the angular plate 157 revolves, it flips the desiccant particles inside the drying mechanism 6. That is, the longer the welding time of the workpiece, the more frequent the flipping frequency of the angular plate 157 for the desiccant particles, and the drying air flow is discharged into the welding mechanism 2 through the air flow groove. Through the above cooperation, the moisture generated inside the welding mechanism 2 during long-term welding is effectively dried by relying on the drying gas, and the moisture inside the welding mechanism 2 is rigorously monitored by means of the humidity sensor 147, so as to avoid the humidity index being greater than the constant index, thereby increasing the possibility of welding laser scattering, and at the same time avoiding damage to the welded parts due to moisture erosion, thus reducing their own use accuracy.
