The movable plate 509 is connected to the inner wall of the base 1, and the movable plate 509 is in contact with the vibrating circular plate 511. Before the device is started, the connecting rod nut to be welded is placed on the top area of ​​the reciprocating screw rod 501. At this time, the device will start, the motor 4 will start, and the output end of the motor 4 will drive the reciprocating screw rod 501 to rotate. The rotation of the reciprocating screw rod 501 will drive the movable round block 503 on the surface of the reciprocating screw rod 501 to rotate, and the movable round block 503 will drive the long connecting block 504 to rotate, but at this time the long connecting block 504 is in contact with the inner wall of the base 1 and is limited by the base 1 so that the long connecting block 504 can only slide on the inner wall of the base 1, so that the movable round block 503 can only move back and forth left and right through the reciprocating groove on the surface of the reciprocating screw rod 501. When the movable circular block 503 is turned on, the long connecting block 504 will move back and forth left and right.

During the upward movement, movable plate 509 contacts the bottom of vibrating circular plate 511. At this time, movable plate 509 continues to rise and strikes vibrating circular plate 511, causing it to vibrate. This shakes off the welding slag and drops it through the opening of vibrating circular plate 511 itself into the conical open column 703 at the bottom. This allows the device to clean the welding slag on vibrating circular plate 511 to a certain extent after long-term welding, ensuring that the welding slag on the top of vibrating circular plate 511 does not affect the quality of the next welding, thereby improving the smoothness of the device.

[0016] The pushing mechanism 6 includes a connecting cylinder 601, a protective cover 602, and a roller 603. One end of the connecting cylinder 601 is fixedly connected to the rear side of the long connecting block 504, and the protective cover 602 is fixedly connected to the other end of the connecting cylinder 601. The roller 603 is rotatably connected to the inner wall of the protective cover 602. When the device is started, the motor 4 is started, and the motor 4 drives the reciprocating screw 501 to rotate. The reciprocating screw 501 drives the long connecting block 504 to move. During the movement of the long connecting block 504, the long connecting block 504 drives the connecting cylinder 601 to move, and the movement of the connecting cylinder 601 drives the protective cover 602 to move. The movement of the protective cover 602 drives its own roller 603 to move, and the roller 603 is connected to the top of the base 1. 603 is in contact with the outside of the welding machine, and the protective cover 602 is in contact with the outside of the welding machine. When the protective cover 602 drives the roller 603 to move, the roller 603 will rotate and roll under the contact and movement with the surface of the base 1, making the movement of the protective cover 602 smoother and smoother. After the connecting cylinder 601 drives the protective cover 602 to move a distance, the protective cover 602 can isolate most of the welding area. The isolation protection of the protective cover 602 can prevent the human eye from contacting the strong light during laser welding and causing damage to the human eye.

The pushing mechanism 6 also includes a pulley 1 604, a belt 605, a pulley 2 606, a reciprocating screw rod 2 607, a long connecting block 608, a movable connecting plate 609, The push scraper 610, the fixed seat 611, the pulley 1 604 are fixedly connected to the circumferential surface of the reciprocating screw rod 1 501, the belt 605 is connected to the surface of the pulley 1 604 for transmission, the pulley 2 606 is connected to the inner wall of the belt 605 for transmission, the reciprocating screw rod 2 607 is fixedly connected to the inner wall of the pulley 2 606, the fixed seat 611 is fixedly connected to the top of the base 1, the reciprocating screw rod 2 607 is rotatably connected to the inner wall of the fixed seat 611, the long connecting block 608 is movably connected to the circumferential surface of the reciprocating screw rod 2 607, one end of the movable connecting plate 609 is rotatably connected to the inner wall of the long connecting block 608, the push scraper 610 is rotatably connected to the other end of the movable connecting plate 609, the roller 603 is in contact with the top of the base 1, and the push scraper 610 is connected to the welding table 51 0 contact, the long connecting block 608 is in contact with the base 1. After the welding is completed, the reciprocating screw rod 1 501 will drive the pulley 1 604 to rotate, and the rotation of the pulley 1 604 will drive the belt 605 to move, and the belt 605 will drive the pulley 2 606 to rotate. The rotation of the pulley 2 606 will drive the reciprocating screw rod 2 607 to rotate, and the rotation of the reciprocating screw rod 2 607 will drive the long connecting block 608 to rotate, but the long connecting block 608 is in contact with the top of the base 1 and is limited by the base 1. At this time, the long connecting block 608 can only move back and forth left and right through the reciprocating groove on the surface of the reciprocating screw rod 2 607. The left and right reciprocating movement of the long connecting block 608 will drive the movable connecting plate 609 to move, and the movement of the movable connecting plate 609 will drive the push scraper 610 to move.Because the movable connecting plate 609 is rotatably connected to the inner wall of the long connecting block 608 and is also rotatably connected to the bottom of the pushing and scraping plate 610, during the movement of the movable connecting plate 609, the movable connecting plate 609 will drive the pushing and scraping plate 610 to move back and forth along the surface of the welding table 510. After the pushing and scraping plate 610 moves a certain distance, it will push the welded parts, making it easier to collect the welded parts, avoiding the safety hazards caused by workers getting too close to the welding arm 2 during manual collection, and also reducing the cost of manual collection.

[0017] Working principle: Before the device is started, the connecting rod nut to be welded is placed on the top area of ​​the reciprocating screw rod 501. At this time, the device will start, the motor 4 will start, and the output end of the motor 4 will drive the reciprocating screw rod 501 to rotate. The rotation of the reciprocating screw rod 501 will drive the movable round block 503 on the surface of the reciprocating screw rod 501 to rotate, and the movable round block 503 will drive the long connecting block 504 to rotate. However, at this time, the long connecting block 504 is in contact with the inner wall of the base 1 and is limited by the base 1 so that the long connecting block 504 can only slide on the inner wall of the base 1, so that the movable round block 503 can only move left and right through the reciprocating groove on the surface of the reciprocating screw rod 501. The movable circular block 503 will also drive the long connecting block 504 to move back and forth left and right. The reciprocating left and right movement of the long connecting block 504 will drive the elastic telescopic rod 505 to move back and forth left and right. The elastic telescopic rod 505 will drive the three-sided clamping block 506 to move back and forth left and right. During the movement of the three-sided clamping block 506, the three-sided clamping block 506 will contact the connecting rod nut in the top area of ​​the vibrating circular plate 511 and push and squeeze the connecting rod nut. At this time, the three-sided clamping blocks 506 on the left and right sides approach each other at the same time, and the two three-sided clamping blocks 506 squeeze the connecting rod nut at the same time. The inner side of the three-sided clamping block 506 is set to a triangle. The two three-sided clamping blocks 506 At the same time, they gather together and can wrap around both sides of the nut that fixes the connecting rod nut, ensuring that when the connecting rod nut is laser welded, the connecting rod nut that needs to be welded will not be offset, thereby improving the accuracy of the device in laser welding, ensuring the quality of the parts after welding, and reducing welding waste. After the three-sided clamping block 506 clamps and welds the parts, when the long connecting block 504 moves back and forth horizontally, the movement of the long connecting block 504 will drive its own pushing block 507 to move. After the pushing block 507 moves a certain distance, the pushing block 507 will contact the moving plate 509 and squeeze and push the moving plate 509. The pushing block 507 will squeeze and push the moving plate 509 during the movement. Plate 509 makes the movable plate 509 rise and move along the inner wall of the fixed block 2 508. During the rising process, the movable plate 509 will contact the bottom of the vibrating circular plate 511. At this time, the movable plate 509 continues to rise, and the movable plate 509 will knock the vibrating circular plate 511, causing the vibrating circular plate 511 to vibrate, and the welding slag after welding will be shaken off and fall into the conical open column 703 at the bottom through the opening of the vibrating circular plate 511 itself. After the equipment has been welding for a long time, the welding slag at the vibrating circular plate 511 can be cleaned to a certain extent, ensuring that the welding slag on the top of the vibrating circular plate 511 cannot affect the quality of the next welding, thereby improving the smoothness of the device.

[0018] When the device is started, the motor 4 will start, and the motor 4 will drive the reciprocating screw 501 to rotate, and the reciprocating screw 501 will drive the long connecting block 504 to move. During the movement of the long connecting block 504, the long connecting block 504 will drive the connecting cylinder 601 to move, and the movement of the connecting cylinder 601 will drive the protective cover 602 to move, and the movement of the protective cover 602 will drive its own roller 603 to move, and the roller 603 will contact the top of the base 1. In the process of the protective cover 602 driving the roller 603 to move, the roller 603 will contact the surface of the base 1 and move. The protective cover 602 rotates and rolls under the action of the movement, making the movement of the protective cover 602 smoother and smoother. After the connecting cylinder 601 drives the protective cover 602 to move a distance, the protective cover 602 can isolate most of the welding area. The isolation protection of the protective cover 602 can prevent the human eye from contacting the strong light during laser welding and causing damage to the human eye. At the same time, it can improve the device during welding, reduce the influence of external factors on welding, and improve the safety performance of the device welding. After the welding is completed, the reciprocating screw rod 501 will drive the pulley 604 to rotate, and the rotation of the pulley 604 will drive As the belt 605 moves, the belt 605 drives the pulley 2 606 to rotate, and the rotation of the pulley 2 606 drives the reciprocating screw rod 2 607 to rotate, and the rotation of the reciprocating screw rod 2 607 drives the long connecting block 608 to rotate, but the long connecting block 608 contacts the top of the base 1 and is limited by the base 1. At this time, the long connecting block 608 can only move back and forth left and right through the reciprocating groove on the surface of the reciprocating screw rod 2 607. The left and right reciprocating movement of the long connecting block 608 drives the movable connecting plate 609 to move, and the movement of the movable connecting plate 609 drives the push scraper 610 to move. The movable connecting plate 609 is rotatably connected to the inner wall of the long connecting block 608, and the movable connecting plate 609 is also rotatably connected to the bottom of the pushing scraper 610. Therefore, during the movement of the movable connecting plate 609, the movable connecting plate 609 will drive the pushing scraper 610 to move back and forth along the surface of the welding table 510. After the pushing scraper 610 moves a certain distance, the pushing scraper 610 will push the welded parts, making the welded parts easier to collect, avoiding the safety hazards caused by the worker being too close to the welding arm 2 during manual collection, and also reducing the cost of manual collection.

At this time, the outer cylinder 701 is stationary, and the inner cylinder 702 rotates inside the outer cylinder 701. The welding slag and impurities on the surface of the vibrating circular plate 511 will fall into the interior of the conical open column 703 through the opening at the top of the vibrating circular plate 511, and then be pushed by the knocking of the movable plate 509. The vibrating circular plate 511 will drive the conical open column 703 to rise. After the force of the movable plate 509 ends, the conical open column 703 will be reset by gravity. This movement will have a certain vibration effect on the conical open column 703, so that the welding slag and debris inside the conical open column 703 can slide into the interior of the outer cylinder 701 through the slope inside the conical open column 703. At this time, the rotation of the inner cylinder 702 will drive the welding slag and debris to rotate to the bottom, so that the welding slag and debris can pass through the bottom of the outer cylinder 701 The opening at the bottom falls into the internal area of ​​the collection box 708, which can ensure that the welding slag and debris after welding are gathered to a certain extent, and avoid the welding slag and debris being scattered on the inner walls around the collection box 708, increasing the difficulty of subsequent cleaning of welding slag and debris, reducing the difficulty of manual cleaning, and improving the efficiency of the device. At the same time, the rotation of the inner cylinder 702 will separate the agglomerated welding slag and disperse it for easy subsequent recycling. The detection mechanism 7 also includes an L-plate 704, a hinged cylinder 705, a knocking plate 706, and an inclined block 707. The L-plate 704 is fixedly connected to the front side of the long connecting block 504, the hinged cylinder 705 is rotatably connected to the inner wall of the welding table 510 by a torsion spring, the knocking plate 706 is fixedly connected to the inner wall of the hinged cylinder 705, and the inclined block 707 is fixedly connected At the top of the knocking plate 706, the L plate 704 contacts the base 1, the knocking plate 706 contacts the welding table 510, the outer cylinder 701 contacts the inner cylinder 702, the knocking plate 706 contacts the inner wall of the base 1, and the outer cylinder 701 is fixed to the inner wall of the collection box 708 through the connecting rod. At the same time, during the movement of the long connecting block 504, the long connecting block 504 will drive the L plate 704 to move. After the L plate 704 moves a certain distance, the L plate 704 will contact the inclined block 707 and squeeze and push the inclined block 707. The L plate 704 pushes the inclined block 707 to move through its own arc area. The movement of the inclined block 707 will drive the knocking plate 706 to rotate to a certain position with the hinged cylinder 705 as the center. When the pushing and squeezing force of the L plate 704 ends,The hinged cylinder 705 is reset by the torsion spring, and the knocking plate 706 knocks on the welded parts during the reset process to test the quality of the welded parts. The knocking test can be used to evaluate the uniformity and integrity of the weld and ensure that there are no defects caused by overheating, uneven cooling or improper operation, thereby ensuring the strength and reliability of the welded joint and improving the efficiency of the device.

[0020] Working principle: When the device is started, the rotation of the reciprocating screw 501 will drive the inner cylinder 702 to rotate, and the outer cylinder 701 is rotatably connected to the circumferential surface of the welding table 510. At this time, the outer cylinder 701 is stationary, and the inner cylinder 702 rotates inside the outer cylinder 701. The welding slag and impurities on the surface of the vibrating circular plate 511 will fall into the interior of the conical open column 703 through the opening at the top of the vibrating circular plate 511. Then, after being knocked and pushed by the moving plate 509, the vibrating circular plate 511 will drive the conical open column 703 to rise. Under the force structure of the moving plate 509, the inner cylinder 702 rotates inside the outer cylinder 701. After the beam is bundled, the conical open column 703 will be reset by gravity. This movement will have a certain vibration effect on the conical open column 703, so that the welding slag and debris inside the conical open column 703 can slide into the interior of the outer cylinder 701 through the slope inside the conical open column 703. At this time, the rotation of the inner cylinder 702 will drive the welding slag and debris to the bottom, so that the welding slag and debris can fall into the inner area of ​​the collection box 708 through the opening at the bottom of the outer cylinder 701, which can ensure that the welding slag and debris after welding are gathered to a certain extent, and avoid the welding slag and debris being scattered in the collection box. The inner wall around 708 increases the difficulty of cleaning the subsequent welding slag and debris, reduces the difficulty of manual cleaning, and improves the efficiency of the device. At the same time, the rotation of the inner cylinder 702 will separate the agglomerated welding slag, making it easier to disperse and facilitate subsequent cleaning. At the same time, in the process of moving the long connecting block 504, the long connecting block 504 will drive the L plate 704 to move. After the L plate 704 moves a certain distance, the L plate 704 will contact the inclined block 707 and squeeze and push the inclined block 707. The L plate 704 pushes the inclined block 707 to move through its own arc area, and the inclined block 707 The movement will drive the knocking plate 706 to rotate to a certain position with the hinged cylinder 705 as the center. When the pushing and squeezing force of the L plate 704 ends, the hinged cylinder 705 will be reset by the torsion spring. The knocking plate 706 will knock on the welded parts during the resetting process to detect the quality of the welded parts. Through the knocking detection, the uniformity and integrity of the weld can be evaluated to ensure that the weld has no defects caused by overheating, uneven cooling or improper operation, thereby ensuring the strength and reliability of the welded joint and improving the utilization efficiency of the device.
