Description

Technical Field

[0001] The utility model relates to a laser welding machine, in particular to a multi-station laser welding machine. Background Art

[0002] Laser welding is a device that uses a high-energy-density laser beam as a heat source for welding. It is widely used in precision machining, aerospace, automotive manufacturing, medical equipment, and other fields, and is highly favored due to its many unique advantages.

[0003] Most existing welding machines can usually only perform welding operations at one workstation, resulting in only one pair of weldments being welded at a time. This requires more downtime for loading and unloading a pair of weldments, greatly reducing overall production efficiency. In addition, when welding a pair of weldments, it is necessary to weld the front and back joints of the pair of weldments. After the front joint is welded, the machine needs to be stopped and manually flipped over to weld the back joint of the pair of weldments, further increasing operation time and labor intensity.

[0004] Therefore, a multi-station laser welding machine is particularly needed to solve the above problems. Utility Model Content

[0024] The following description is merely a preferred embodiment of the present invention and does not limit the scope of protection of the present invention.

[0025] Example: A multi-station laser welding machine, such as Figures 1-6As shown, it includes a first electric slide 1, a second electric slide 101, an electric slide 102, a servo motor 103, a welding head 2, a base 3, a baffle 5, a rotating rod 6, a drive motor 10, a support plate 11, a disc 12, a stepping motor 13, a connecting rod 14 and a clamping assembly. The first electric slide 1 is connected to the top left of the base 3 near the edge by means of bolts, the second electric slide 101 is slidably connected to the upper part of the first electric slide 1, the electric slide 102 is slidably connected to the front of the second electric slide 101, the servo motor 103 is connected to the outside of the right end of the electric slide 102 by means of bolts, the welding head 2 is connected to the output shaft of the servo motor 103 by means of a key connection, and the support plate 11 is fixed to the top right of the base 3 near the edge. The driving motor 10 is connected to the upper inner part of the base 3 by bolts, the rotating rod 6 is connected to the output shaft of the driving motor 10 by key connection, and multiple baffles 5 are connected to the outer upper end of the rotating rod 6 by welding, and multiple baffles 5 are distributed at intervals in the circumferential direction. The disc 12 is connected to the outer lower end of the rotating rod 6 by welding. A plurality of workstations are provided on the disc 12, and the bottom surface of the disc 12 is in rotational contact with the top surface of the support plate 11. The bottom surfaces of the multiple baffles 5 are in contact with different positions of the top surface of the disc 12 respectively. A plurality of connecting rods 14 are connected to the disc 12 by welding, and the plurality of connecting rods 14 are distributed at intervals in the circumferential direction. The stepping motor 13 is connected to the middle position of the connecting rod 14 by bolt connection, and the clamping assembly is arranged on the output shaft of the stepping motor 13.

[0026] like Figure 4-Figure 6 As shown, the clamping assembly includes a bidirectional cylinder 15, a connecting plate 16, a splint 17, a top plate 18, a screw 21 and a rotating block 22. The bidirectional cylinder 15 is connected to the output shaft of the stepper motor 13 by bolts, and the top plate 18 is connected to the outer lower side of the bidirectional cylinder 15 by welding. The two connecting plates 16 are respectively connected to the two telescopic rods of the bidirectional cylinder 15 by key connections. The splint 17 is rotatably connected to the bottom of the connecting plate 16. Each top plate 18 is located between every two laterally aligned connecting plates 16. The screw 21 is threadedly connected between the splint 17 and the connecting plate 16. The rotating block 22 is rotatably connected to the top of the connecting plate 16, and the rotating block 22 is threadedly connected to the screw 21.

[0027] like Figure 1 As shown, a controller 301 is also included, which is connected to the right front side of the outside of the base 3 by bolts, and the controller 301 is electrically connected to the first electric slide rail 1, the second electric slide rail 101, the electric slide seat 102, the servo motor 103, the welding head 2, the drive motor 10, the stepper motor 13 and the bidirectional cylinder 15.

[0028] like Figure 5As shown, it also includes a slide rod 19 and a second spring 20. Multiple slide rods 19 are slidably connected to the side of the splint 17 facing the top plate 18. Multiple slide rods 19 are distributed in a rectangular array, and a second spring 20 for assisting reset is connected between the slide rod 19 and the splint 17. A rubber block is provided at one end of the slide rod 19 close to the two-way cylinder 14 to prevent the slide rod 19 from scratching the weldment 1201.

[0029] like Figure 1-Figure 2 As shown, it also includes a collecting frame 4, a fence plate 7, a first spring 8 and a scraper 9. The fence plate 7 is connected to the top of the base 3 by welding, and the fence plate 7 is located below the baffle 5 and the disc 12. An opening for discharging is provided on the left side. Multiple scrapers 9 are slidably connected to the inside of the lower end of the rotating rod 6, and the bottom surface of the scraper 9 contacts the top surface of the base 3. A first spring 8 for assisting reset is connected between the scraper 9 and the rotating rod 6. A collecting frame 4 is inserted into the left side of the outside of the base 3, and the opening of the fence plate 7 is directly opposite to the top of the collecting frame 4, so that metal debris falling out of the opening falls into the inside of the collecting frame 4, and the length of the collecting frame 4 is greater than the length of the opening.

[0030] First, write the operating program of the first electric slide 1, the second electric slide 101, the electric slide 102, the servo motor 103 and the welding head 2 into the controller 301, and then put a pair of weldments 1201 together and place them on the support plate 11, so that the joint of the pair of weldments 1201 forms a V-shaped angle. At this time, the V-shaped angle contacts the top plate 18, so that the pair of weldments 1201 are limited. Then rotate the turning block 22 clockwise to move the screw 21 upward and disconnect it from the splint 17, release the lock between the splint 17 and the connecting plate 16, and then rotate the splint 17 to a suitable angle until its slope is aligned with the edge of the weldment 1201. After alignment, rotate the turning block 22 counterclockwise to move the screw 21 downward and reconnect it to the splint 17, and then the splint 17 After the weld is firmly clamped, the first electric slide rail 1 and the second electric slide rail 1 are started and shut down, so that the output shaft of the drive motor 10 is intermittently driven to rotate the disc 12 90 degrees clockwise, so that the other three clamping components are directly above the support plate 11, and the above steps are repeated to clamp the other three pairs of welds 1201, and then the first electric slide rail 1 and the second electric slide rail 1 are started. The slide rail 101 and the second electric slide rail 101 slide left and right to the appropriate position according to the set path, and the electric slide seat 102 slides downward to the appropriate position according to the set path until the welding head 2 is aligned with the front splicing of a pair of weldments 1201, and then the welding head 2 and the servo motor 103 are started. The output shaft of the servo motor 103 drives the welding head 2 to rotate to the appropriate angle according to the set path, and completely welds the front splicing of the pair of weldments 1201. After the welding of the front splicing is completed, the servo motor 103 and the welding head 2 are automatically turned off. At this time, the stepper motor 13 is started, and the output shaft of the stepper motor 13 drives the two-way cylinder 15 to rotate 180 degrees according to the set path, so that the pair of weldments 1201 are turned over. After turning over, the welding head 2 and the servo motor 103 are started again. The servo motor 103 and the output shaft of the servo motor 103 drive the welding head 2 to reverse to the appropriate angle and reset according to the set path, and completely weld the reverse joint of the pair of weldments 1201, thereby completing the welding operation of a pair of weldments 1201, and then repeat the above steps to make multiple pairs of weldments 1201 be located under the welding head 2 in sequence for welding operations. When multiple pairs of weldments 1201 are welded, repeat the above steps to make multiple pairs of weldments 1201 aligned with the support plate 11 in turn, control the two telescopic rods of the two-way cylinder 15 to extend, and make the two connecting plates 16 drive the two clamps 17 to move outward to release a pair of weldments 1201, and the second spring 20 then returns to its original state, prompting the slide bar 19 to pop out from the inside of the clamp 17, and finally remove the weldment 1201.

[0031] It is worth noting that during the welding process, the baffle 5 plays a protective role to prevent the splashing slag from falling on the unwelded pair of weldments 1201. At the same time, the generated metal debris will fall on the base 3 and be intercepted by the fence plate 7. When the next batch of weldments 1201 are welded, the rotating rod 6 drives the scraper 9 to rotate clockwise to scrape the metal debris on the base 3, so that these metal debris fall out of the opening of the fence plate 7 and fall into the collection frame 4. When the scraper 9 rotates, under the action of the first spring 8, it clings to the inner wall of the fence plate 7 to fully scrape the metal debris.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
