Description

Technical Field

[0001] This utility model relates to the field of automotive parts processing, and in particular to an automated laser welding production equipment. Background Technology

[0002] In the field of new energy vehicle electric drive system component manufacturing, copper plate tubes, as key conductive components, require welding to achieve a permanent connection between the plate and the tube. Currently, the process involves operators first mechanically assembling and positioning the tube and plate, and then using TIG (tungsten inert gas welding) or MIG (methane inert gas welding) to weld the connection area, thereby completing the processing of the component. However, the high-temperature electric arc during the welding process causes metal vapor and shielding gas to react, producing harmful gases containing ozone, nitrogen oxides and metal fumes, which can cause irreversible occupational health damage to the operator's respiratory system. Furthermore, welding quality is highly dependent on the operator maintaining continuous and stable hand gestures and visual focus. This high-intensity work mode can easily lead to visual fatigue and muscle strain, resulting in problems such as decreased welding speed and poor weld consistency as working time increases, ultimately restricting production efficiency.

The platform 41 is provided with a feeding area 411, a transfer area 412, and a receiving area 413. In this embodiment, the transfer area 412 is preferably located between the feeding area 411 and the receiving area 413, so that the feeding area 411, the transfer area 412, and the receiving area 413 are arranged in a straight line.

The reciprocating motor 421 is fixedly connected to the bottom of the platform 41, the first pulley is rotatably connected to the bottom of the platform 41, and the output shaft of the reciprocating motor 421 is fixedly connected to a second pulley. A transmission belt 422 is fitted on the first pulley and the second pulley. Furthermore, a guide rail is fixedly connected to the bottom of the platform 41, the guide rail is parallel to the through groove 414, the transmission belt 422 is parallel to the through groove 414, a slide block is slidably connected to the guide rail, and the transmission belt 422 is fixedly connected to the slide block; a lifting cylinder 423 is provided on the reciprocating assembly 42, the lifting cylinder 423 is fixedly connected to the slide block, and a lever 424 is fixedly connected to the output shaft of the lifting cylinder 423, the lever 424 is located in the through groove 414; the output shaft of the reciprocating motor 421 drives the transmission belt 422 to move back and forth through the second pulley, so that the slide block slides back and forth on the guide rail, driving the lifting cylinder 423 and the lever 424 to move back and forth between the feeding area 411, the transfer area 412 and the receiving area 413.

[0026] The feeding area 411 is equipped with a feeding rack 43, which includes four first supports. The first supports are located at the four corners of the feeding area 411. The feeding rack 43 has a first opening, which is located on two of the first supports. The first supports are installed on the platform 41 at a certain angle. When multiple trays are stacked in the four first supports, the first supports will guide the trays to be arranged in a stepped staggered manner, thereby preventing the edge of the lower tray from getting stuck in the bottom of the upper tray. The height of the first opening only allows one tray to pass through. Furthermore, a receiving rack 44 is provided in the receiving area 413. The receiving rack 44 includes four second supports, which are located at the four corners of the receiving area 413. A second opening is provided on the receiving rack 44, which is located on two of the second supports. Both the first opening and the second opening are close to the transfer area 412. The height of the second opening is only allowed to pass through one tray. Furthermore, the platform 41 is provided with slots. In this embodiment, it is preferred that there are two slots, which are arranged at intervals and pass through the platform 41. The slots are located in the receiving area 413. The platform 41 is provided with a push cylinder 45, which is placed on the table surface of the workbench 1 and fixedly connected thereto. The output shaft of the push cylinder 45 is fixedly connected to a push rod 451. The middle part of the push rod 451 is fixedly connected to the output shaft of the push cylinder 45.

Furthermore, both sides of the receiving area 413 are rotatably connected to limit plates 46. The limit plates 46 are equipped with coil springs, which are located at the rotatable connection between the limit plates 46 and the platform 41. The two ends of the coil springs respectively abut against the limit plates 46 and the platform 41. The coil springs push the limit plates 46 to rotate toward the receiving area 413. The limit plates 46 are provided with rotation restrictions. When the limit plates 46 stop rotating, there is a gap of one tray height between the limit plates 46 and the bottom of the receiving area 413. The reciprocating motor 421 drives the paddle 424 to move below the feeding area 411. The output shaft of the lifting cylinder 423 pushes the paddle 424 to rise, so that it touches and supports the bottom tray located in the feeding area 411. Then, the reciprocating motor 421 drives the paddle 424 and the tray to move below the transfer area 412. During this process, the paddle 424 pulls the tray out from the first opening and transfers it into the transfer area 412. When the reciprocating motor 421 drives the paddle 424 to move to the area below the receiving zone 413, the paddle 424 simultaneously pulls the material tray out of the transfer zone 412 and into the receiving zone 413 through the second opening; then the output shaft of the lifting cylinder 423 pulls the paddle 424 down to reset, so that it is separated from the material tray; the output shaft of the push cylinder 45 drives the push rod 451 through the corresponding slot, pushing the material tray up. During the rising process of the material tray, the two ends of the material tray push the two limiting plates 46 to rotate and open on the platform 41, so that the material tray rises smoothly above the limiting plates 46; after the pushing force of the material tray is lost, the coil spring drives the limiting plates 46 to reset, and under the limitation of the rotation angle, the limiting plates 46 are below the material tray; after the output shaft of the push cylinder 45 pulls the push rod 451 to reset, the material tray is stably placed on the limiting plates 46, so that the material tray is stored between the four second supports; Through the above process, the entire operation of automatically removing the material tray from the feeding rack 43 and transferring it to the receiving rack 44 via the transfer area 412 is realized.

[0027] The platform 41 is equipped with a two-dimensional moving mechanism 47 and a gripper 473. The two-dimensional moving mechanism 47 includes a second traveling device 471 and a second lifting device 472. In this embodiment, the second traveling device 471 and the second lifting device 472 are preferably both lead screw devices. Lead screw devices are existing mature technologies and will not be described in detail in this embodiment. The second traveling device 471 is fixedly connected to the receiving rack 44. The second traveling device 471 is placed horizontally and a second connecting seat is slidably connected to the second traveling device 471. The second lifting device 472 is fixedly connected to the second connecting seat. The second traveling device 471 and the second lifting device 472 are perpendicular to each other. Furthermore, the gripper 473 is slidably connected to the second lifting device 472, and the second traveling device 471 drives the second lifting device 472 to perform translational reciprocating motion through the second connecting seat. The second lifting device 472 drives the gripper 473 to perform lifting motion. The second traveling device 471 drives the gripper 473 to move back and forth between the top of the clamping assembly and the top of the transfer area 412, and the second lifting device 472 drives the gripper 473 to descend and approach the clamping assembly or the transfer area 412.

The first lifting device 31, the first traveling device 32, and the rotating component work together to drive the laser welding device 34 to adjust to the processing position facing the fixture component; the turntable motor 211 adjusts the rotation angle of the disc body 22 through the gearbox 21 to change the angle of the fixture component; the multi-axis linkage mechanism 3 works in coordination with the turntable mechanism 2 to complete the welding between the copper plate and the copper tube by the laser welding device 34; after the welding is completed, the multi-axis linkage mechanism 3 drives the laser welding device 34 to withdraw, and the sensor 24 detects the weld. The reciprocating component 42 of the unloading mechanism 6 operates, pulling the empty material tray into the transfer area 412; its two-dimensional moving mechanism 47 drives the gripper 473 to move above the clamping component, clamping the welded copper plate and copper tube assembly, and transferring and placing them into the empty material tray in the transfer area 412.
