Description

Technical Field

[0001] The present invention relates to the technical field of laser welding, and particularly to a laser welding pressing device. Background Art

[0002] Laser welding is a welding method that uses a laser beam with a high energy density as a heat source to join two or more workpieces together. The laser beam is focused on the area to be welded, causing the material to quickly melt and fuse, forming a strong connection. This welding technology belongs to modern advanced manufacturing technology and can achieve high-precision and high-quality connections, and has been widely used in many industrial fields.

[0003] In the related technical field of the patent pressing device with the publication number CN218745792U, particularly a laser welding pressing device, which includes a working platform, a first pressing assembly, and a second pressing assembly; the first pressing assembly includes a lower presser, a control seat, a driving rod, and a first driving motor arranged in sequence from top to bottom, and the second pressing assembly includes a presser, a left-right adjuster, and a second driving motor. This disclosure greatly improves the pressing accuracy for different materials or workpieces by setting the working platform, the first pressing assembly, and the second pressing assembly.

[0004] During the use of the above device, it is difficult to quickly load the workpieces to be welded. Quick loading is one of the key links to ensure the continuous and efficient operation of the production line. If the loading speed is slow, it will directly lead to a slower rhythm of the entire laser welding production line, a reduction in the number of welded workpieces that can be completed per unit time, an extension of the production cycle of each workpiece, an inability to fully utilize the performance of the laser welding equipment, a decrease in the utilization rate of the equipment, and thus a significant reduction in the overall production efficiency. Therefore, a laser welding pressing device is proposed to solve the above-mentioned problems. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a laser welding pressing device in view of the deficiencies in the above-mentioned prior art.

[0006] To solve the above technical problems, the technical solution adopted by the present invention is: a laser welding pressing device, including a workbench, a clamping device is arranged at the bottom of the workbench, a cleaning device is arranged at the bottom of the workbench, and a discharging device is arranged at the bottom of the workbench; the clamping device includes a support plate, a cylinder, a moving plate, a top rod, an upper moving table, a fixing plate I, a hinged plate I, and a clamping plate. The support plate is fixedly connected to the bottom of the workbench, the cylinder is fixedly connected to the top of the support plate, the moving plate is fixedly connected to the telescopic end of the cylinder. By driving the moving plate to move through the cylinder, rapid feeding of the workpiece can be achieved. When the workpiece can be fed rapidly, the rhythm of the entire laser welding production line can be accelerated. During the laser welding process, pressing the workpiece is to ensure the position accuracy and welding quality of the workpiece during welding. If the feeding speed is fast, the utilization rate of the equipment is improved, thereby enhancing the production efficiency of the entire laser welding process. The top rod is fixedly connected to the top of the moving plate, the upper moving table is fixedly connected to the top of the top rod, the fixing plate I is fixedly connected to the bottom of the upper moving table, the hinged plate I is hinged to the inner wall of the fixing plate I through a torsion spring, the clamping plate is fixedly connected to the left side of the hinged plate I, the outer wall of the hinged plate I is slidably connected to the inner wall of the workbench, the bottom of the clamping plate is in contact with the top of the workbench, the circumferential surface of the top rod is slidably connected to the inner wall of the workbench, and the top of the moving plate is in contact with the top of the workbench. The movement of the hinged plate I drives the movement of the clamping plate. By moving the upper moving table up and down, the workpiece is squeezed and pressed, so that the workpiece is clamped to ensure the accuracy of the welding position. During the laser welding process, the clamping of the workpiece can firmly fix the workpiece at a predetermined position. When the pressing operation is performed, appropriate clamping can prevent the workpiece from displacing in the horizontal and vertical directions, ensuring the accuracy of the welding position.

[0007] Preferably, the cleaning device includes a guide plate, a first spring, a vertical plate, a brush, a concave plate, a second fixing plate, and a push plate. The guide plate is slidably connected to the inner wall of the upper moving table. The first spring is fixedly connected to the left side of the guide plate. The brush is fixedly connected to the bottom of the guide plate. After the brush moves to brush off impurities and rust on the workpiece, when laser welding and pressing are carried out, it can provide a cleaner surface for the subsequent welding process. The presence of impurities and rust will introduce defects during welding, such as pores, slag inclusions, etc., affecting the continuity and strength of the weld. After removing these impurities, in the pressed state, the laser beam can better act on the pure metal surface of the workpiece, making the weld fusion more sufficient and uniform, improving the quality and strength of the weld. After the workpiece is welded, the vertical plate is fixedly connected to the front of the brush. The concave plate is fixedly connected to the top of the workbench. The second fixing plate is fixedly connected to the left side of the upper moving table. The push plate is fixedly connected to the front of the vertical plate. The bottom of the push plate is in contact with the top of the workbench. The front of the first spring is fixedly connected to the rear of the second fixing plate. The welded workpiece is quickly discharged through the movement of the push plate. When the push plate can quickly move to discharge the welded workpiece, the technological process of the entire laser welding production line can proceed smoothly. This means that once the welding and pressing operations are completed, the workpiece can quickly leave the welding station, making room for the next workpiece to be welded to enter and perform pressing and welding operations, reducing the waiting time and improving the overall production efficiency of the equipment.

[0008] Preferably, the discharging device includes a third fixing plate, a Z-shaped plate, an inclined plate, and a second spring. The third fixing plate is fixedly connected to the front of the push plate. The Z-shaped plate is fixedly connected to the right side of the third fixing plate. The inclined plate is fixedly connected to the right side of the Z-shaped plate. The second spring is fixedly connected to the bottom of the upper moving table. The discharging device further includes a contact plate, a scraping plate, a pressing plate, and a second hinged plate. The contact plate is fixedly connected to the bottom of the second spring. The scraping plate is fixedly connected to the bottom of the contact plate. The movement of the scraping plate quickly scrapes off the welding slag adhering to the workpiece. Welding slag is a by-product that may be generated after laser welding. Its adhesion to the workpiece will affect subsequent welding operations. When the scraping plate moves to scrape off the welding slag, when subsequent laser welding and pressing are carried out, it can prevent the welding slag from entering the new weld, reducing the possibility of slag inclusions in the weld. Slag inclusions will reduce the strength, toughness, and sealing performance of the weld, affecting the performance of the welded joint. Timely removal of the welding slag can ensure the quality of the subsequent weld, making the weld more firm and reliable. The pressing plate is fixedly connected to the left side of the scraping plate. The second hinged plate is hinged to the inner wall of the workbench through a torsion spring. The bottom of the pressing plate is in contact with the top of the second hinged plate. The bottom of the scraping plate is in contact with the top of the workbench. The movement of the scraping plate drives the movement of the pressing plate, so that when the pressing plate moves, it presses the second hinged plate to form an inclined sliding track, enabling the workpiece to smoothly enter the collection box for collection.

[0009] The present invention adopts the above technical solution, which can bring the following beneficial effects: 1. For the adjustable laser welding pressing device, through the mutual cooperation among the support plate, cylinder, moving plate, ejector rod, upper moving table, fixed plate I, hinged plate I, and clamping plate, when the device is started, the moving plate is driven by the cylinder to move to achieve rapid feeding of the workpiece. When the workpiece can be rapidly fed, the rhythm of the entire laser welding production line can be accelerated. During the laser welding process, pressing the workpiece is to ensure the position accuracy and welding quality of the workpiece during welding. If the feeding speed is fast, the utilization rate of the equipment is improved, thereby enhancing the production efficiency of the entire laser welding process. The movement of the hinged plate I drives the movement of the clamping plate, and the workpiece is squeezed and pressed by the up and down movement of the upper moving table, so that the workpiece is clamped to ensure the accuracy of the welding position. During the laser welding process, the clamping of the workpiece can firmly fix the workpiece at a predetermined position. When the pressing operation is performed, appropriate clamping can prevent the workpiece from displacing in the horizontal and vertical directions, ensuring the accuracy of the welding position.

[0010] 2. For the adjustable laser welding pressing device, through the mutual cooperation among the guide plate, spring I, vertical plate, brush, concave plate, fixed plate II, and push plate, when the brush moves and brushes off the impurities and rust on the workpiece, a cleaner surface can be provided for the subsequent welding process during the laser welding pressing. The presence of impurities and rust will introduce defects such as pores and slag inclusions during welding, affecting the continuity and strength of the weld. After removing these impurities, in the pressed state, the laser beam can better act on the pure metal surface of the workpiece, making the weld fusion more sufficient and uniform, improving the quality and strength of the weld. When the workpiece welding is completed, the welded workpiece is rapidly discharged by the movement of the push plate. When the push plate can rapidly move and discharge the welded workpiece, the technological process of the entire laser welding production line proceeds smoothly. This means that once the welding and pressing operations are completed, the workpiece can quickly leave the welding station, making room for the next workpiece to be welded to enter and perform the pressing and welding operations, reducing the waiting time and improving the overall production efficiency of the equipment.

[0011] 3. The adjustable laser welding pressing device cooperates with the third fixing plate, Z-shaped plate, inclined plate, contact plate, second spring, scraping plate, pressing plate, and second hinge plate. The movement of the scraping plate quickly removes the welding slag adhering to the workpiece. The welding slag is a by-product that may be generated after laser welding. Its adhesion to the workpiece will affect subsequent welding operations. When the scraping plate moves to remove the welding slag, during subsequent laser welding pressing, it can prevent the welding slag from entering the new weld seam, reducing the possibility of slag inclusion in the weld seam. Slag inclusion will reduce the strength, toughness, and sealing performance of the weld seam, affecting the performance of the welded joint. Timely removal of the welding slag can ensure the quality of the subsequent weld seam, making the weld seam stronger and more reliable. The movement of the scraping plate drives the movement of the pressing plate, causing the pressing plate to press the second hinge plate to form an inclined landslide track when moving, enabling the workpiece to smoothly enter the collection box for collection.

Detailed Embodiment

[0014] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0015] Please refer to Figures 1-7 An embodiment of the present invention is: a laser welding pressing device, including a workbench 1, a clamping device 2 is arranged at the bottom of the workbench 1, a cleaning device 3 is arranged at the bottom of the workbench 1, and a discharging device 4 is arranged at the bottom of the workbench 1; the clamping device 2 includes a support plate 201, a cylinder 202, a moving plate 203, a top rod 204, an upward moving platform 205, a first fixing plate 206, a first hinged plate 207, and a clamping plate 208. The support plate 201 is fixedly connected to the bottom of the workbench 1, the cylinder 202 is fixedly connected to the top of the support plate 201, and the moving plate 203 is fixedly connected to the telescopic end of the cylinder 202. When the device is started, the moving plate 203 is driven to move by the cylinder 202. The moving plate 203 moves, and by placing the workpiece on the moving plate 203, the cylinder 202 drives the moving plate 203 to move to achieve rapid feeding of the workpiece. When the workpiece can be rapidly fed, the rhythm of the entire laser welding production line can be accelerated. During laser welding, pressing the workpiece is to ensure the position accuracy and welding quality of the workpiece during laser welding. If the feeding speed is fast, it means that more workpieces can be sent into the laser welding station for pressing and laser welding operations per unit time, reducing the waiting time of the equipment due to too long feeding time, improving the utilization rate of the equipment, and thus enhancing the production efficiency of the entire laser welding process. The top rod 204 is fixedly connected to the top of the moving plate 203, the upward moving platform 205 is fixedly connected to the top of the top rod 204, the first fixing plate 206 is fixedly connected to the bottom of the upward moving platform 205, the first hinged plate 207 is hinged to the inner wall of the first fixing plate 206 through a torsion spring, the clamping plate 208 is fixedly connected to the left side of the first hinged plate 207, the outer wall of the first hinged plate 207 is slidably connected to the inner wall of the workbench 1, the bottom of the clamping plate 208 is in contact with the top of the workbench 1, the circumferential surface of the top rod 204 is slidably connected to the inner wall of the workbench 1, and the top of the moving plate 203 is in contact with the top of the workbench 1. By moving the upward moving platform 205 up and down to drive the first fixing plate 206 to move, the first fixing plate 206 moves to drive the first hinged plate 207 to move, and the first hinged plate 207 moves to drive the clamping plate 208 to move. By moving the upward moving platform 205 up and down, the workpiece is squeezed and pressed, so that the workpiece can be clamped to ensure the accuracy of the welding position. During laser welding, the clamping of the workpiece can firmly fix the workpiece in a predetermined position. When the pressing operation is performed, proper clamping can prevent the workpiece from displacing in the horizontal and vertical directions, ensuring the accuracy of the welding position. In this way, the laser beam can accurately act on the part that needs laser welding, avoiding the deviation of the weld from the designed position due to the displacement of the workpiece, ensuring the shape and dimensional accuracy of the laser welding joint, and improving the welding quality.

[0016] The cleaning device 3 includes a guide plate 301, a first spring 302, a vertical plate 303, a brush 304, a concave plate 305, a second fixing plate 306, and a push plate 307. The guide plate 301 is slidably connected to the inner wall of the upper moving table 205. The first spring 302 is fixedly connected to the left side of the guide plate 301. The brush 304 is fixedly connected to the bottom of the guide plate 301. The movement of the upper moving table 205 drives the guide plate 301 to move up and down. When the guide plate 301 moves, it will contact the concave plate 305, causing the guide plate 301 to move backward. The movement of the guide plate 301 drives the brush 304 to move. The movement of the brush 304 brushes off the impurities and rust on the workpiece to be welded. When the brush 304 moves and brushes off the impurities and rust on the workpiece, during laser welding and pressing, it can provide a cleaner surface for the subsequent welding process. The presence of impurities and rust will introduce defects during welding, such as pores and slag inclusions, affecting the continuity and strength of the weld. After removing these impurities, in the pressed state, the laser beam can better act on the pure metal surface of the workpiece, making the weld fusion more sufficient and uniform, improving the quality and strength of the weld. When the laser welding of the workpiece is completed, the vertical plate 303 is fixedly connected to the front of the brush 304. The concave plate 305 is fixedly connected to the top of the workbench 1. The second fixing plate 306 is fixedly connected to the left side of the upper moving table 205. The push plate 307 is fixedly connected to the front of the vertical plate 303. The bottom of the push plate 307 contacts the top of the workbench 1. The front of the first spring 302 is fixedly connected to the rear of the second fixing plate 306. The movement of the brush 304 drives the vertical plate 303 to move. The movement of the vertical plate 303 drives the push plate 307 to move. The movement of the push plate 307 quickly discharges the welded workpiece. When the push plate 307 can move quickly and discharge the welded workpiece, the technological process of the entire laser welding production line proceeds smoothly. This means that once the welding and pressing operations are completed, the workpiece can quickly leave the laser welding station, making room for the next workpiece to be laser welded to enter and perform pressing and welding operations, reducing the waiting time and improving the overall production efficiency of the equipment.

[0017] Working principle: When the device starts, the cylinder 202 drives the moving plate 203 to move. As the moving plate 203 moves, by placing the workpiece on the moving plate 203 and driving the moving plate 203 to move through the cylinder 202, rapid feeding of the workpiece is achieved. When the workpiece can be rapidly fed, the rhythm of the entire laser welding production line can be accelerated. During the laser welding process, clamping the workpiece is to ensure the position accuracy and welding quality of the workpiece during welding. If the feeding speed is fast, it means that more workpieces can be fed into the laser welding station for clamping and welding operations per unit time, reducing the waiting time of the equipment caused by too long feeding time, improving the utilization rate of the equipment, and thus enhancing the production efficiency of the entire laser welding process. By moving the upper moving platform 205 up and down, the fixed plate one 206 is driven to move. When the fixed plate one 206 moves, the articulated plate one 207 is driven to move. When the articulated plate one 207 moves, the clamping plate 208 is driven to move. By moving the upper moving platform 205 up and down, the workpiece is squeezed and clamped, so that the workpiece is held, ensuring the accuracy of the welding position. During the laser welding process, the clamping of the workpiece can firmly fix the workpiece at a predetermined position. When the clamping operation is performed, appropriate clamping can prevent the workpiece from displacing in the horizontal and vertical directions, ensuring the accuracy of the welding position. In this way, the laser beam can accurately act on the part to be welded, avoiding the deviation of the weld from the designed position due to the displacement of the workpiece, ensuring the shape and dimensional accuracy of the welded joint, and improving the laser welding quality.

[0018] By moving the upper moving platform 205, the guide plate 301 is driven to move up and down. When the guide plate 301 moves, it will contact the concave plate 305, causing the guide plate 301 to move backward. When the guide plate 301 moves, the brush 304 is driven to move. By moving the brush 304, the impurities and rust on the workpiece to be welded are brushed off. When the brush 304 moves and brushes off the impurities and rust on the workpiece, a cleaner surface can be provided for the subsequent welding process during laser welding and clamping. The presence of impurities and rust will introduce defects during welding, such as pores and slag inclusions, affecting the continuity and strength of the weld. After removing these impurities, in the clamped state, the laser beam can better act on the pure metal surface of the workpiece, making the weld fusion more sufficient and uniform, and improving the quality and strength of the weld. When the laser welding of the workpiece is completed, by moving the brush 304, the vertical plate 303 is driven to move. When the vertical plate 303 moves, the push plate 307 is driven to move. By moving the push plate 307, rapid discharging of the welded workpiece is achieved. When the push plate 307 can move quickly and discharge the welded workpiece, the technological process of the entire laser welding production line can proceed smoothly. This means that once the welding and clamping operations are completed, the workpiece can quickly leave the laser welding station, making room for the next workpiece to be laser welded to enter and perform clamping and welding operations, reducing the waiting time and improving the overall production efficiency of the equipment.

[0019] Please refer toFigures 1-7 , on the basis of the above embodiment, in another embodiment of the present invention, the discharging device 4 includes a third fixing plate 401, a Z-shaped plate 402, an inclined plate 403, and a second spring 405. The third fixing plate 401 is fixedly connected to the front part of the pushing plate 307. The Z-shaped plate 402 is fixedly connected to the right side of the third fixing plate 401. The inclined plate 403 is fixedly connected to the right side of the Z-shaped plate 402. The second spring 405 is fixedly connected to the bottom of the upward moving table 205. The discharging device 4 further includes a contact plate 404, a scraping plate 406, a pressing plate 407, and a second hinged plate 408. The contact plate 404 is fixedly connected to the bottom of the second spring 405. The scraping plate 406 is fixedly connected to the bottom of the contact plate 404. The movement of the pushing plate 307 drives the movement of the third fixing plate 401. The movement of the third fixing plate 401 drives the movement of the Z-shaped plate 402. The movement of the Z-shaped plate 402 drives the movement of the inclined plate 403. When the inclined plate 403 moves, it will contact the contact plate 404, causing the contact plate 404 to move downward. The movement of the contact plate 404 drives the movement of the scraping plate 406. The movement of the scraping plate 406 enables the welding slag attached to the workpiece to be quickly scraped off. The welding slag is a by-product that may be generated after laser welding. Its attachment to the workpiece will affect subsequent welding operations. When the scraping plate 406 moves to scrape off the welding slag, when laser welding is pressed subsequently, it can prevent the welding slag from entering a new weld seam, reducing the possibility of slag inclusion in the weld seam. Slag inclusion will reduce the strength, toughness, and sealing performance of the weld seam, affecting the performance of the welded joint. And timely removal of the welding slag can ensure the quality of subsequent weld seams, making the weld seams more firm and reliable. The pressing plate 407 is fixedly connected to the left side of the scraping plate 406. The second hinged plate 408 is hinged to the inner wall of the workbench 1 through a torsion spring. The bottom of the pressing plate 407 contacts the top of the second hinged plate 408. The bottom of the scraping plate 406 contacts the top of the workbench 1. The movement of the scraping plate 406 drives the movement of the pressing plate 407, causing the pressing plate 407 to press the second hinged plate 408 to form an inclined landslide track when it moves, enabling the workpiece to smoothly enter the collection box for collection.

[0020] Working principle: The movement of the push plate 307 drives the movement of the third fixed plate 401. The movement of the third fixed plate 401 drives the movement of the Z-shaped plate 402. The movement of the Z-shaped plate 402 drives the movement of the inclined plate 403. When the inclined plate 403 moves, it will contact the contact plate 404, causing the contact plate 404 to move downward. The movement of the contact plate 404 drives the movement of the scraper 406. The movement of the scraper 406 enables the slag adhering to the workpiece to be quickly scraped off. The slag is a by-product that may be generated after laser welding. Its adhesion to the workpiece will affect subsequent laser welding operations. When the scraper 406 moves to scrape off the slag, when subsequent laser welding and pressing are carried out, the slag can be prevented from entering the new weld, reducing the possibility of slag inclusion in the weld. Slag inclusion will reduce the strength, toughness and sealing performance of the weld, affecting the performance of the welded joint. And timely removal of the slag can ensure the quality of the subsequent weld, making the weld more firm and reliable. The movement of the scraper 406 drives the movement of the pressing plate 407, causing the pressing plate 407 to press the second hinged plate 408 to form an inclined landslide track when it moves, enabling the workpiece to smoothly enter the collection box for collection.
