Description

Technical Field

[0001] The present invention relates to the technical field of laser welding, and in particular to a laser welding device for metal part processing. Background Art

[0002] In the field of metal part processing, laser welding, as an efficient and precise welding technology, is widely used in many industries such as automobile manufacturing, aerospace, and electronic equipment due to its many advantages such as fast welding speed, small heat-affected zone, and high weld quality. With the continuous improvement of industrial automation and intelligence levels, higher requirements are also put forward for the performance and functions of laser welding devices. It is not only necessary to ensure the welding quality, but also to improve production efficiency, reduce operation difficulty and labor costs.

[0003] In terms of clamping, the clamping devices of most devices are simply designed and have limited precision. Most use fixed-size or single-form components, making it difficult to adapt to metal workpieces of different shapes, sizes, and materials. Facing irregularly shaped workpieces, the clamping is unstable and prone to shaking and displacement, affecting the welding precision and quality. Moreover, some clamping devices will damage the surface of the workpiece, affecting the appearance and strength performance.

[0004] In terms of position adjustment, the positioning system of the device has low precision and cannot accurately adjust the workpiece to the required position, resulting in welding deviation and misalignment. The position adjustment mechanism is cumbersome to operate and slow in speed. In production scenarios where frequent part replacement or welding position adjustment is required, manual adjustment is time-consuming and laborious, reducing production efficiency and increasing labor intensity.

[0005] In the loading process, traditional manual or simple mechanical-assisted loading methods are inefficient and have large errors. Manual loading is likely to place the workpiece in an inaccurate position. The loading device lacks an alignment and positioning function, and it is difficult to ensure the position and posture of the workpiece before entering the welding area. Extra adjustment and correction are required, increasing the production time cost. Moreover, in batch production, the existing loading methods are difficult to achieve automation and continuity, and cannot form an efficient production line with subsequent processes.

[0006] During flipping welding, some devices do not have a flipping device. For multi-sided welding, it is necessary to manually take out, flip, and reinstall, which is a cumbersome process and easily damages the workpiece. For some devices with a flipping device, the mechanism design is unreasonable, the flipping speed is slow, the stability is poor, the operation is complex, the requirements for personnel skills are high, and the training cost is large.

[0007] In the unloading stage, most are manual operations. It is a safety hazard and slow for operators to enter the equipment area to pick up parts, affecting the continuous operation of the equipment. Some unloading devices are simply designed and lack automated and intelligent control. They cannot automatically classify and unload, easily causing workpiece accumulation and chaos, increasing the workload of sorting and reducing production efficiency.

[0008] In summary, there are many problems in the existing laser welding equipment during metal part processing, which restrict the development and application of laser welding technology. Therefore, developing new equipment has practical significance and market value. Summary of the Invention

[0009] In view of the above situation, to overcome the defects of the existing technology, the present invention provides a laser welding equipment for metal part processing, which effectively solves the problems of poor clamping adaptability and easy damage to parts, low positioning accuracy and cumbersome adjustment, low feeding efficiency and large error, inconvenient flipping, potential safety hazards during unloading, low efficiency and poor automation of the existing laser welding equipment.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] 1. In the present invention, by controlling the rotation and telescopic movement of the electric push rod, the right side of the frame body is tilted downward to drive the bottom plate to tilt synchronously. When feeding, only the bottom of the workpiece needs to be aligned with the frame body, and it is not necessary to align both ends completely, which significantly improves the feeding efficiency.

[0024] 3.

And because the bottom plate is fixed, the rotation of the frame body will not cause interference, which is convenient for laser welding of the other side of the workpiece.

[0025] 4. After welding is completed, control the electric push rod to rotate so that the gas enters the rectangular tube. Under the action of air pressure, the clamping plates move outward simultaneously to release the clamping. Then the control valve cuts off the connection with the telescopic tube, the cylinder is communicated with the outside, the electric push rod rotates and extends to make the frame body move horizontally to the left, and the left electric push rod contracts to make the frame body tilt, and the workpiece slides down relying on the inclined bottom plate to realize rapid blanking.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0039] As Figures 1 - 10 presented, the present invention proposes a laser welding device for metal part processing:

[0040] The present invention includes a machine platform 102. A support platform 103 is provided on the top of the machine platform 102. The support platform 103 serves as the core working base. A laser welding machine 104 is provided at the rear side of the top of the support platform 103. The equipped focusing lens and high-power laser emitter can accurately perform micron-level welding operations, and can achieve accurate welding operations from millimeter level to micron level, meeting the processing requirements of workpieces with different materials. A receiving platform 101 is provided on the left side of the machine platform 102 for receiving the welded materials. A support plate 105 is provided on the top of the machine platform 102. The position of the support plate 105 remains unchanged to provide support for the above components. A loading plate 107 is provided on the top of the support plate 105. A lead screw 106 is provided at the bottom of the loading plate 107. The lead screw 106 is rotatably connected to the support plate 105. The lead screw 106 is rotated by a motor. The rotation of the lead screw 106 can enable the loading plate 107 to move left and right on the top of the support plate 105 for long-distance loading and unloading of materials. Other components achieve small-scale movement and angle adjustment. A support component is provided at the middle top of the loading plate 107 to support the bottom of the material. An adjustment component is provided at the rear top of the loading plate 107. A connecting plate 304 is provided at the top of the adjustment component. A frame 305 is provided at the front end of the connecting plate 304. The adjustment component can change the position of the connecting plate 304 and drive the frame 305 to flip, realizing the front and back side switching of the workpiece to be welded.

[0041] An active telescopic rod 401 is provided at the bottom of the adjustment component. The active telescopic rod 401 can actively expand and contract according to requirements. A driven component is provided at the front end of the active telescopic rod 401. A rectangular tube 406 is provided at the top of the driven component. The rectangular tube 406 is connected to the frame 305. Two clamping plates 504 are provided on the left side of the rectangular tube 406. The two clamping plates 504 are arranged symmetrically left and right with the center line of the rectangular tube 406 as the axis of symmetry. Through the cooperation of the active telescopic rod 401 and the driven component, the two clamping plates 504 can move simultaneously inward or outward to complete the clamping of workpieces of different sizes.

[0042] The support assembly includes a first spring 201. The bottom of the first spring 201 is connected to the support plate 105. The top of the first spring 201 is provided with a bottom plate 202. The first spring 201 can support the bottom plate 202. The bottom plate 202 can be raised or lowered and tilted in any direction. When subjected to non-uniform loads, the bottom plate 202 automatically completes horizontal correction through the differential compression amounts of the springs. At the same time, the ball joint allows the bottom plate 202 to maintain surface flatness in the tilted state.

[0043] The adjustment assembly includes a second rack 310. The right side of the second rack 310 is connected to the active telescopic rod 401. The telescopic movement of the active telescopic rod 401 can drive the two second racks 310 to move left and right. The bottom of the second rack 310 is provided with two second gears 309. The second rack 310 can drive the second gears 309 at the bottom to rotate, thereby realizing the angle adjustment of the two electric push rods 302. There is a vertical plate 301 behind the two second gears 309. The bottom of the vertical plate 301 is connected to the support plate 105. The two second gears 309 are arranged symmetrically left and right with the center line of the vertical plate 301 as the axis of symmetry. There is an electric push rod 302 behind each second gear 309. The top of the electric push rod 302 is connected to the connecting plate 304. The two electric push rods 302 perform synchronous telescopic movements. The vertical plate 301, the electric push rods 302, and the connecting plate 304 form a parallelogram structure. When the two electric push rods 302 rotate to the right and extend simultaneously, they can drive the connecting plate 304 at the top to move horizontally to the right and lower in height while moving. Subsequently, the two electric push rods 302 rotate to the left and shorten in length at the same time, realizing the horizontal movement of the connecting plate 304 to the right. When the connecting plate 304 moves to the middle position, laser welding is performed. After the welding is completed, the two electric push rods 302 continue to rotate to the left and actively extend simultaneously, causing the connecting plate 304 to move to the left and lower in height for the material removal operation after welding.

[0044] The front end of the top of the right electric push rod 302 is provided with a first gear 306. The first gear 306 is rotatably connected to the connecting plate 304. The bottom of the first gear 306 is provided with a first rack 303. The right side of the first rack 303 is provided with an electric telescopic rod 307. The front end of the electric telescopic rod 307 is connected to the connecting plate 304. The first gear 306 is connected to the frame 305. The first gear 306 is fixedly connected to the frame 305 through a pin shaft. When the two electric push rods 302 rotate, they will not drive the frame 305 to rotate. Only when the electric telescopic rod 307 actively telescopic drives the first rack 303 to move, and then drives the meshing first gear 306 to rotate, can the angle adjustment of the frame 305 be realized to adapt to different states.

[0045] The driven component includes a piston rod 402. The rear end of the piston rod 402 is connected to the active telescopic rod 401. A cylinder 404 is provided outside the piston rod 402. The bottom of the cylinder 404 is connected to the support plate 105. While driving the second rack 310 to move, the active telescopic rod 401 can drive the piston rod 402 to move left and right. When the piston rod 402 moves, the gas inside the cylinder 404 can be discharged or inhaled.

[0046] A control valve 407 is provided on the right side of the cylinder 404. The control valve 407 can control the communication state between the cylinder 404 and the telescopic tube 405. When the control valve 407 is closed, the through hole at its top will be opened synchronously to connect the cylinder 404 with the outside. When the control valve 407 is in communication with the telescopic tube 405, the through hole at the top of the control valve 407 will not be connected to the outside. The telescopic tube 405 is provided at the top of the control valve 407. The top of the telescopic tube 405 is connected to the rectangular tube 406. The telescopic tube 405 can be correspondingly elongated according to the rotation of the frame 305. An electromagnetic plate 403 is provided at the top of the cylinder 404. The electromagnetic plate 403 can generate a magnetic force after being energized to adsorb and fix the bottom plate 202, and does not generate a magnetic force when not energized.

[0047] A second spring 501 is provided in the middle of the rectangular tube 406. Two electromagnetic blocks 502 are provided outside the second spring 501. The electromagnetic blocks 502 are generally composed of a coil, an iron core and an armature, etc. The iron core and the armature are generally made of soft magnetic materials. When the coil is energized, a magnetic field is established to generate magnetic flux, and the iron core and the armature are magnetized to generate electromagnetic suction. The two electromagnetic blocks 502 are arranged symmetrically front and back with the center line of the rectangular tube 406 as the axis of symmetry. When the gas inside the rectangular tube 406 increases, the two electromagnetic blocks 502 will be pushed to move outward simultaneously under the action of air pressure. When the gas inside the rectangular tube 406 decreases, the two electromagnetic blocks 502 will be pulled to move inward simultaneously under the action of the second spring 501. A cross bar 503 is provided outside the electromagnetic block 502. The outside of the cross bar 503 is connected to the clamping plate 504. The electromagnetic block 502 drives the fixedly connected cross bar 503 to move inward, so as to realize the clamping of the workpiece by the two clamping plates 504. When the position of the workpiece needs to be finely adjusted, the fixed positions of the two electromagnetic blocks 502 are correspondingly controlled, and the center point position of the two clamping plates 504 is completed in cooperation with the active telescopic rod 401.

[0048] Specifically, when it is necessary to receive materials, control the two electric push rods 302 to rotate to the right at the same time, and the two electric push rods 302 extend synchronously, so that the clamping plate 504 moves slightly to the right. Subsequently, the right electric push rod 302 contracts, driving the right side of the frame 305 to tilt downward. While tilting, it will press the bottom plate 202 at the bottom to tilt synchronously. At this time, the feeding operation is carried out. Since the bottom plate 202 is tilted, at this time, only the bottom of the workpiece needs to be aligned with the frame 305, and it is not necessary for the worker to align both ends completely, which improves the feeding efficiency. Subsequently, the two electric push rods 302 rotate to the left and contract while moving, so that the frame 305 can always maintain a horizontal movement and move to the initial position, that is, the bottom of the laser welding machine 104. While the two electric push rods 302 rotate to the left, the piston rod 402 also moves to the left, generating negative pressure inside the cylinder 404. At this time, the control valve 407 is in a connected state, and the gas inside the rectangular pipe 406 can be pumped into the cylinder 404. Under the action of the second spring 501, the two electromagnetic blocks 502 can be pulled to move inward at the same time, and the workpiece is centered and clamped by the two clamping plates 504, and then laser welding is carried out.

[0049] If it is necessary to finely adjust the center position of the workpiece before laser welding, assuming that it is necessary to adjust the position of the workpiece forward at this time, then control the active telescopic rod 401 to contract, drive the electric push rod 302 to rotate to the right, and realize the horizontal movement of the frame 305 to the right (become the workpiece feeding state in the previous paragraph). Subsequently, the rear electromagnetic block 502 is energized to generate magnetic force and adsorb with the rectangular pipe 406. The position of the rear electromagnetic block 502 remains unchanged, and the gas in the cylinder 404 enters the rectangular pipe 406, thereby pushing the front electromagnetic block 502 forward. When it moves to the predetermined position, the front electromagnetic block 502 is energized to generate magnetic force and adsorb with the rectangular pipe 406. Subsequently, the rear electromagnetic block 502 is de-energized and the magnetic force disappears. Under the action of the second spring 501, the rear electromagnetic block 502 will be pulled forward, so that the rear clamping plate 504 moves forward and pushes the workpiece forward to complete the adjustment of the center position of the workpiece, and then continue to carry out laser welding.

[0050] When it is necessary to weld the other side of the workpiece, first control the two electric push rods 302 to contract, press the bottom plate 202 through the frame 305, and at the same time, the electromagnetic plate 403 is energized to generate magnetic force to adsorb the bottom of the bottom plate 202, and fix the bottom plate 202 at the lowest position. Subsequently, the two electric push rods 302 extend to drive the frame 305 to rise, and control the electric telescopic rod 307 to extend to realize the rotation of the frame 305 by 180 degrees, complete the flipping of the workpiece, and carry out laser welding on the other side of the workpiece. And because the bottom plate 202 is fixed at the lowest point, there will be no interference when the frame 305 rotates.

[0051] After welding is completed, control the two electric push rods 302 to rotate to the right. While rotating, gas enters the inside of the rectangular tube 406. At this time, under the action of air pressure, the two clamping plates 504 move outward simultaneously to release the clamping of the workpiece. Subsequently, the control valve 407 cuts off the connection with the telescopic tube 405, and the air cylinder 404 communicates with the outside. Then, the electric push rod 302 rotates to the left and elongates simultaneously to ensure the horizontal movement of the frame 305. When it moves to the left, control the left electric push rod 302 to contract. The frame 305 becomes inclined and presses the left side of the bottom plate 202 to also incline downward. Subsequently, the workpiece slides to the left relying on the inclined bottom plate 202 to achieve rapid blanking.

[0052] It should be noted that: by controlling the rotation and telescoping of the electric push rod 302, the right side of the frame 305 inclines downward to drive the bottom plate 202 to incline synchronously. When discharging the material, only the bottom of the workpiece needs to be aligned with the frame 305, and it is not necessary to align both ends completely, which significantly improves the discharging efficiency. During the process of the electric push rod 302 rotating and contracting to the left, negative pressure is generated inside the air cylinder 404, and the gas inside the rectangular tube 406 is pumped into the air cylinder 404. Under the action of the second spring 501, the electromagnetic block 502 is pulled to move inward to realize the centering clamping of the clamping plate 504 on the workpiece, ensuring the accurate welding position. When fine adjustment of the central position of the workpiece is required, through the cooperation of controlling the active telescopic rod 401, the energized state of the electromagnetic block 502, and the second spring 501, precise adjustment of the workpiece in the front and back directions can be achieved to meet different welding requirements. When welding the other side of the workpiece is required, control the electric push rod 302 to contract and press down the frame 305, and the electromagnetic plate 403 is energized to adsorb the bottom plate 202 to fix its position. Then, the electric push rod 302 elongates to drive the frame 305 to rise and rotate 180 degrees to complete the flipping of the workpiece. And because the bottom plate 202 is fixed, the rotation of the frame 305 will not cause interference, which is convenient for laser welding of the other side of the workpiece. After welding is completed, control the electric push rod 302 to rotate so that gas enters the inside of the rectangular tube 406. Under the action of air pressure, the clamping plates 504 move outward simultaneously to release the clamping. Then, the control valve 407 cuts off the connection with the telescopic tube 405, and the air cylinder 404 communicates with the outside. The electric push rod 302 rotates and elongates to make the frame 305 move horizontally to the left. The left electric push rod 302 contracts to make the frame 305 inclined, and the workpiece slides down relying on the inclined bottom plate 202 to achieve rapid blanking.
