Description

Technical Field

[0001] This invention relates to the field of welding technology, specifically to a high-efficiency welding device and method. Background Technology

[0002] The field of welding technology is rapidly developing towards intelligent manufacturing and automation. The combination of high-efficiency processes such as laser welding and arc welding with multi-axis robotic arms and station rotation mechanisms has become a cutting-edge trend in the industry. The industry's requirements for the automation level, operating efficiency, welding accuracy and process linkage of welding equipment are also continuously increasing.

[0003] However, current automated welding equipment still has many technical limitations, making it difficult to meet the demands of large-scale, high-precision industrial production.

[0004] The equipment is mostly used for single-station operation. Double-sided welding requires a complex flipping mechanism, which can easily cause process interruption. In addition, the welding mechanism has insufficient adjustment flexibility and poor plate compatibility.

[0005] Secondly, the integration of the feeding, welding and unloading processes is low, and most of them are independent control modules. The process connection requires manual or transfer mechanism assistance, and it is impossible to achieve fully automated closed-loop operation.

[0006] Secondly, the plate positioning and bonding mechanism has poor linkage with the workstation rotation and welding operations, requiring a separate positioning process. Furthermore, the bonding accuracy of some mechanisms is insufficient, which can easily lead to plate misalignment and poor weld quality, requiring subsequent manual correction.

[0007] Secondly, the redundant design of the transmission and reset mechanisms, along with the separate control of multiple drive sources, can easily lead to asynchronous actions, which increases the manufacturing cost and energy consumption of the equipment, and reduces its operational stability and accuracy.

[0008] To avoid the aforementioned problems affecting efficient welding, a high-efficiency welding equipment and method are proposed to solve the existing problems. Summary of the Invention

The bottom of the inner cavity of the work station slide cavity is provided with a second slide groove that is slidably adapted to the second adjusting plate, and a second spring is fixedly connected between the second slide groove and the second adjusting plate.

[0018] This invention discloses a method for using a high-efficiency welding device, specifically including the following steps:

[0019] S1. Start the first electric telescopic rod. The first electric telescopic rod drives the U-shaped frame to extend. After the U-shaped frame moves to its limit, the welding gun inside the U-shaped frame will enter the welding area at the work station slide cavity. Then, by adjusting the third electric telescopic rod up and down and extending the second electric telescopic rod in two stages, the double-sided welding of the plate to be welded in the corresponding work station can be completed.

[0020] S2. During the movement of the U-shaped frame, the U-shaped frame synchronously drives the movable frame to move. The movable frame moves closer to the half gear and meshes with the half gear. During the meshing process of the half gear, it will drive the rotating column to rotate. The rotating column synchronously drives the flat push plate and T-shaped push plate to move through the first push frame and the second push frame respectively. The movement of the flat push plate will push the plate placed on the top of the feeding conveyor belt into the top of the workpiece bearing slide on the right side which is in an unloaded state.

[0021] The movement of the T-shaped pusher plate will push the plate that has been welded on the top of the rear workpiece bearing slide to move until the welded plate enters the top of the unloading conveyor belt;

[0022] As the toothed plate continues to move, the half gear and the toothed plate finish meshing. At this time, the flat push plate and the T-shaped push plate will push the first push frame and the second push frame to reset by their own reset, causing the rotating column to reset to its original rotation position.

[0023] When the toothed plate initially moves, it engages with the half gear through the positioning and guidance of the L-shaped stop, the back plate, and the cover plate. As the toothed plate continues to move, the L-shaped stop connected to the toothed plate will enter the interior of the inclined groove through the through-hole, causing the toothed plate to move away from the half gear. When the first electric telescopic rod drives the U-shaped frame to reset, the corresponding toothed plate will return to its original position in a state away from the half gear. Specifically, the L-shaped stop slides inside the inclined groove and finally pushes open the cover plate and moves back to the front side of the back plate when the inclined groove climbs up, thus creating a prerequisite for the next unidirectional drive of the rotating column.

[0024] S3. After the two welding guns have completed the double-sided welding of the plate by adjusting the up and down of the third electric telescopic rod and the two-stage movement adjustment of the second electric telescopic rod, the third electric telescopic rod, the second electric telescopic rod and the first electric telescopic rod are reset in sequence. The reset of the extension end of the first electric telescopic rod drives the U-shaped frame to reset. After the U-shaped frame is reset, the control button on the front side of the vertical plate will be pressed. After the control button is triggered, the stepper motor is automatically started. After the stepper motor starts, it drives the station rotary table to rotate 90 degrees intermittently through the output shaft.

[0025] The rotating table drives several workpiece bearing slides to change positions. The movement of the workpiece bearing slides drives the column to move. The column slides slide up and down on the stepped annular groove track on the surface of the ring plate through guide rollers.

[0026] As the original right-side workpiece carrier slide moves to the front, the guide rollers on the bottom column surface move from the high half-ring groove of the stepped annular groove track to the low half-ring groove, causing the original left-side workpiece carrier slide to descend as it moves to the front. When the workpiece carrier slide carrying the unwelded plate descends inside the work station slide cavity, the first and second extrusion grooves at the top of the workpiece carrier slide will respectively squeeze the first and second adjustment plates, causing the two plates to be welded at the top of the workpiece carrier slide to fit together through the centering adjustment of the first and second adjustment plates and the sliding assistance of the drag-reducing balls, so that the weld can be welded subsequently.

[0027] When the original left-side workpiece bearing slide moves to the rear, the guide roller on the bottom column surface will move from the lower half-ring groove of the stepped ring groove track to the upper half-ring groove, causing the workpiece bearing slide to return to its original height and release the center clamp on the welded plate so as to connect the unloading action of the T-shaped push plate.

[0028] Beneficial effects

[0029] This invention provides a high-efficiency welding device and method. Compared with existing technologies, it has the following advantages:

[0030] (1) The high-efficiency welding equipment and method, by setting a double-sided welding adjustment mechanism, a plate positioning and bonding mechanism and an automatic loading and unloading mechanism on the top of the base, enables the device to achieve high coordination between the double-sided welding adjustment mechanism, the plate positioning and bonding mechanism and the automatic loading and unloading mechanism. This enables the device to organically integrate and precisely trigger multiple processes such as welding adjustment, automatic plate positioning and bonding, loading of plates to be welded, unloading of finished plates and station rotation in the entire welding operation process. The actions of each mechanism are linked in sequence without any gaps, thereby achieving the effect of automated closed-loop operation of the entire welding operation process. This completely breaks the limitations of traditional equipment where single-process independent operation and manual or transfer mechanism assistance are required between processes, and greatly improves the efficiency, continuity and automation level of the overall welding operation.

[0031] (2) The high-efficiency welding equipment and method, by setting a slide guide column and slide return spring that are compatible with the workpiece bearing slide inside the work station slide cavity, and combining the high and low position track adjustment design of the plate positioning and fitting mechanism, enables the workpiece bearing slide to automatically complete lifting, clamping and material release actions during work station switching. The overall structure design is compact and the action is smoothly connected. There is no need to configure additional independent drive components for lifting and clamping. This simplifies the overall structure of the equipment, reduces the difficulty and cost of daily maintenance of the equipment, and further improves the efficiency and smoothness of work station switching.

[0032] (3) The high-efficiency welding equipment and method adopt a design mode of single drive source triggering multiple mechanism linkage with the first electric telescopic rod as the core. The action of the welding adjustment mechanism is used as the core trigger point to synchronously drive a series of supporting actions such as loading, unloading, station rotation, and plate positioning. This replaces the traditional equipment design of multiple drive sources controlling each mechanism separately, reduces the design redundancy of transmission and reset mechanisms, reduces the manufacturing cost and operating energy consumption of the equipment, and avoids problems such as asynchronous action and connection error caused by poor coordination of multiple drive sources. This greatly improves the stability of equipment operation and the accuracy of action execution. Attached Figure Description

[0059] This invention discloses a method for using a high-efficiency welding device, specifically including the following steps:

[0060] S1. Start the first electric telescopic rod 501. The first electric telescopic rod 501 drives the U-shaped frame 502 to extend. After the U-shaped frame 502 moves to its limit, the welding gun 505 inside the U-shaped frame 502 will enter the welding area at the work station slide cavity 3. Then, by adjusting the third electric telescopic rod 504 up and down and extending the second electric telescopic rod 503 in two stages, the double-sided welding of the plate to be welded in the corresponding work station can be completed.

[0061] S2. During the movement of the U-shaped frame 502, the U-shaped frame 502 synchronously drives the movable frame 707 to move. The movable frame 707 gradually moves closer to the half gear 719 and meshes with the half gear 719. During the meshing process of the half gear 719, it will drive the rotating column 704 to rotate. The rotating column 704 synchronously drives the flat push plate 702 and the T-shaped push plate 703 to move through the first push frame 705 and the second push frame 706 respectively. The movement of the flat push plate 702 will push the plate placed on the top of the feeding conveyor belt 701 into the top of the workpiece bearing slide 4 on the right side, which is in an unloaded state.

[0062] The movement of the T-shaped pusher 703 will push the plate after welding on the top of the rear workpiece bearing slide 4 to move until the welded plate enters the top of the unloading conveyor belt 720.

[0063] As the toothed plate 710 continues to move, the meshing stroke between the half gear 719 and the toothed plate 710 ends. At this time, the flat push plate 702 and the T-shaped push plate 703 will push the first push frame 705 and the second push frame 706 to reset by their own reset, causing the rotating column 704 to reset its original rotation position.

[0064] When the toothed plate 710 initially moves, it engages with the half gear 719 through the positioning and guidance of the L-shaped stop 715, the back plate 711, and the cover plate 713. As the toothed plate 710 continues to move, the L-shaped stop 715 connected to the toothed plate 710 will enter the interior of the inclined groove 712 through the through port 716, causing the toothed plate 710 to move away from the half gear 719. When the first electric telescopic rod 501 drives the U-shaped frame 502 to reset, the corresponding toothed plate 710 will return to its original position in a state away from the half gear 719. Specifically, the L-shaped stop 715 slides inside the inclined groove 712 and finally pushes open the cover plate 713 and moves back to the front side of the back plate 711 when the inclined groove 712 is climbing, thus creating a prerequisite for the next one-way drive of the rotating column 704.

[0065] S3. After the two welding guns 505 have completed the double-sided welding of the plate by adjusting the height of the third electric telescopic rod 504 and the two-stage movement adjustment of the second electric telescopic rod 503, the third electric telescopic rod 504, the second electric telescopic rod 503 and the first electric telescopic rod 501 are reset in sequence. The reset of the extension end of the first electric telescopic rod 501 drives the U-shaped frame 502 to reset. After the U-shaped frame 502 is reset, it will press the control button 509 on the front side of the vertical plate 508. After the control button 509 is triggered, it controls the stepper motor 507 to start automatically. After the stepper motor 507 starts, it drives the station rotary table 2 to rotate 90 degrees intermittently through the output shaft.

[0066] The rotating table 2 drives several workpiece bearing slides 4 to change positions in turn. The movement of the workpiece bearing slides 4 drives the column 607 to move. The column 607 slides up and down on the stepped annular groove track 610 on the surface of the ring plate 609 through the guide roller 608.

[0067] As the original right-side workpiece-bearing slide 4 moves to the front, the guide roller 608 on the surface of its bottom column 607 moves from the high half-ring groove of the stepped annular groove track 610 to the low half-ring groove, causing the original left-side workpiece-bearing slide 4 to descend as it moves to the front. When the workpiece-bearing slide 4 carrying the unwelded plate descends inside the work station slide cavity 3, the first extrusion groove 603 and the second extrusion groove 605 on the top of the workpiece-bearing slide 4 will respectively squeeze the first adjusting plate 602 and the second adjusting plate 604, causing the two plates to be welded on the top of the workpiece-bearing slide 4 to fit together through the centering adjustment of the first adjusting plate 602 and the second adjusting plate 604, and with the assistance of the drag-reducing ball 606, so that the weld can be welded later.

[0068] When the original left-side workpiece bearing slide 4 moves to the rear, the guide roller 608 on the surface of its bottom column 607 will move from the lower half-ring groove of the stepped ring groove track 610 to the upper half-ring groove, causing the workpiece bearing slide 4 to return to its original height and release the center clamp on the welded plate so as to connect the unloading action of the T-shaped push plate 703.

9. A method of using a high-efficiency welding equipment, characterized in that: Specifically, the following steps are included: S1. Start the first electric telescopic rod (501). The first electric telescopic rod (501) drives the U-shaped frame (502) to extend. After the U-shaped frame (502) reaches its limit of movement, the welding gun (505) inside the U-shaped frame (502) will enter the welding area at the work station slide cavity (3). Then, by adjusting the third electric telescopic rod (504) up and down and extending the second electric telescopic rod (503) in two stages, the double-sided welding of the plate to be welded in the corresponding work station can be completed. S2. During the movement of the U-shaped frame (502), the U-shaped frame (502) synchronously drives the movable frame (707) to move. The movable frame (707) gradually moves closer to the half gear (719) and meshes with the half gear (719). During the meshing process of the half gear (719), it will drive the rotating column (704) to rotate. The rotating column (704) synchronously drives the flat push plate (702) and the T-shaped push plate (703) to move through the first push frame (705) and the second push frame (706) respectively. The movement of the flat push plate (702) will push the plate placed on the top of the feeding conveyor belt (701) into the top of the workpiece bearing slide (4) on the right side, which is in an unloaded state. The movement of the T-shaped push plate (703) will push the plate after welding on the top of the rear workpiece bearing slide (4) to move until the welded plate enters the top of the unloading conveyor belt (720); As the toothed plate (710) continues to move, the meshing stroke of the half gear (719) and the toothed plate (710) ends. At this time, the flat push plate (702) and the T-shaped push plate (703) will push the first push frame (705) and the second push frame (706) to reset by their own reset, causing the rotating column (704) to reset to its original rotation position. When the toothed plate (710) initially moves, it engages with the half gear (719) through the positioning and guidance of the L-shaped stop (715), the back plate (711) and the cover plate (713). As the toothed plate (710) continues to move, the L-shaped stop (715) connected to the toothed plate (710) will enter the interior of the inclined groove (712) through the through-hole (716), causing the toothed plate (710) to move away from the half gear (719). When the first electric telescopic rod (501) drives the U-shaped frame (502) to reset, the corresponding toothed plate (710) will return to its original position in a state away from the half gear (719). Specifically, the L-shaped stop (715) slides inside the inclined groove (712) and finally pushes open the cover plate (713) when it climbs the inclined surface of the inclined groove (712) and moves back to the front side of the back plate (711) to prepare for the next one-way drive of the rotating column (704). S3. After the two welding guns (505) are adjusted up and down by the third electric telescopic rod (504) and the second electric telescopic rod (503) are adjusted in two stages to complete the double-sided welding of the plate, the third electric telescopic rod (504), the second electric telescopic rod (503) and the first electric telescopic rod (501) are reset in sequence. The extension end of the first electric telescopic rod (501) is reset, which drives the U-shaped frame (502) to reset. After the U-shaped frame (502) is reset, it will press the control button (509) on the front side of the vertical plate (508). After the control button (509) is triggered, it controls the stepper motor (507) to start automatically. After the stepper motor (507) starts, it drives the station rotary table (2) to rotate ninety degrees through the output shaft in a single intermittent motion. The rotating table (2) drives several workpiece bearing slides (4) to rotate in different positions. The workpiece bearing slides (4) move and drive the column (607) to move. The column (607) slides up and down in the stepped annular groove track (610) on the surface of the ring plate (609) through the guide roller (608). During the process of the original right-side workpiece bearing slide (4) moving to the front side, the guide roller (608) on the surface of its bottom column (607) will move from the high half-ring groove of the stepped ring groove track (610) to the low half-ring groove, causing the original left-side workpiece bearing slide (4) to descend during the process of moving to the front side. When the workpiece bearing slide (4) carrying the unwelded plate descends inside the station slide cavity (3), the first extrusion groove (603) and the second extrusion groove (605) on the top of the workpiece bearing slide (4) will squeeze the first adjustment plate (602) and the second adjustment plate (604) respectively, causing the two plates to be welded on the top of the workpiece bearing slide (4) to be aligned by the centering adjustment of the first adjustment plate (602) and the second adjustment plate (604) and the sliding assistance of the drag-reducing ball (606), so that the weld can be welded later. When the corresponding original left-side workpiece bearing slide (4) moves to the rear side, the guide roller (608) on the surface of its bottom column (607) will move from the lower half-ring groove of the stepped ring groove track (610) to the upper half-ring groove, causing the workpiece bearing slide (4) to return to its original height and release the center clamp on the welded plate so as to connect the unloading action of the T-shaped push plate (703).
