Description

Technical Field

[0001] This utility model relates to the field of battery module assembly technology, and in particular to a flight welding device. Background Technology

[0002] In the automated production line for battery module assembly, there is a BSB welding process for the cell terminals. This process uses laser welding to weld the battery strips to the cell terminals, enabling the cells of the battery module to be connected in series and parallel.

[0003] Currently, existing flying welding equipment has the following main shortcomings: (1) When using static welding process, the servo module or robot moves the galvanometer to a position and stops to weld four pieces. Because welding needs to be stopped, the welding efficiency is not high. (2) The piece detection mechanism is directly installed on the copper nozzle crossbeam. The force generated by the downward pressure of the copper nozzle will force the copper nozzle crossbeam to deform, which will result in the inaccuracy of the measured data of the piece detection mechanism. (3) In order to improve the battery energy of the same volume pack, the market adopts module-less battery packs. With the increase in the number of cells, especially the module-less stacking method, the cumulative error of the horizontal and vertical cells in the battery pack is large, which affects the alignment of the copper nozzle. (4) The copper nozzle replacement requires manual removal of the old copper nozzle and then installation of the new copper nozzle, which is time-consuming and labor-intensive, and the replacement efficiency is low. Utility Model Content

[0038] The present invention will now be further described with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0039] like Figure 1 and Figure 2As shown, a flying welding device includes a frame 100, two crossbeams 200 parallel to each other and internally disposed at the top of the frame 100, a robot 300 disposed on one side of the frame 100, a welding mechanism 400 installed at the end of the robot 300, a copper nozzle pressure mechanism 500 installed on the inner sides of the two crossbeams 200, a blister detection mechanism 600 disposed between the two crossbeams 200, a two-dimensional motion mechanism 700 installed on the frame 100 and driving the crossbeams 200 to perform YZ-axis motion, and a three-dimensional motion mechanism 800 installed on the frame 100 and driving the blister detection mechanism 600 to perform XYZ-axis motion. Each crossbeam 200 has multiple copper nozzle pressure mechanisms 500. Two crossbeams 200 press down on two rows of copper nozzles 533 in a stepping motion. While the robot 300 is welding one row of copper nozzles 533, the other crossbeam 200 presses down on the next row of copper nozzles 533 to be welded. This ensures that the pressing of the copper nozzles 533 coincides with the welding time, eliminating the need to stop welding and significantly reducing cycle time, thus greatly improving welding efficiency. Simultaneously, the three-dimensional motion mechanism 800 independently drives the metal strip detection mechanism 600, eliminating the need for it to move with the crossbeams 200. This avoids the adverse effects of crossbeam 200 deformation, making the data measured by the metal strip detection mechanism 600 more reliable, more accurate, and better compatible with subsequent products of different sizes.

[0040] Specifically, the welding mechanism 400 includes a galvanometer, a camera, a laser rangefinder, and an air knife, which are existing technologies and will not be described in detail here; the film inspection mechanism 600 adopts existing technologies.

[0041] like Figure 1 , Figure 5 and Figure 7 As shown, the copper nozzle pressurizing mechanism 500 includes a transverse plate 510, a mounting plate 520, a copper nozzle assembly 530, a pressurizing assembly 540, an X-axis fine-tuning assembly 550, and a Y-axis fine-tuning assembly 560. The transverse plate 510 is slidably mounted on the inner side of the crossbeam 200, and the mounting plate 520 is slidably mounted on the side of the transverse plate 510 away from the crossbeam 200. The copper nozzle assembly 530 is slidably mounted on the bottom end of the mounting plate 520, and the pressurizing assembly 540 is mounted on the top center of the transverse plate 510 with its driving end facing downward and connected to the mounting plate 520. The X-axis fine-tuning assembly 550 is disposed at the top of the crossbeam 200 to drive the transverse plate 510 to move along the X-axis of the crossbeam 200. The Y-axis fine-tuning assembly 560 is disposed between the mounting plate 520 and the copper nozzle assembly 530 to drive the copper nozzle assembly 530 to move along the Y-axis of the mounting plate 520. By setting the X-axis fine-tuning component 550 and the Y-axis fine-tuning component 560, the copper nozzle component 530 is finely adjusted to absorb the cumulative error of the horizontal and vertical rows of cells in the battery pack, thus improving its versatility. Specifically, the pressurization component 540 can be a cylinder.

[0042] like Figure 5 , Figure 7and Figure 8 As shown, the copper nozzle assembly 530 includes a top plate 531, a tooling plate 532, copper nozzles 533, and dust collection pipes 534. The top end of the top plate 531 is slidably connected to the bottom end of the mounting plate 520, and the bottom end of the top plate 531 is connected to the tooling plate 532. Several copper nozzles 533 are arranged in an array at the end of the tooling plate 532 away from the crossbeam 200. Multiple dust collection pipes 534 are installed at the end of the top plate 531 away from the crossbeam 200. Specifically, a slag-blocking sheet metal is also installed at the end of the tooling plate 532 away from the crossbeam 200.

[0043] like Figures 4-8 As shown, the X-axis fine-tuning assembly 550 includes an X-axis slide plate 551, an X-axis rack 552, an X-axis motor 553, and an X-axis gear 554. The X-axis slide plate 551 is slidably mounted on the top of the crossbeam 200 and connected to the top of the transverse plate 510. The X-axis rack 552 is mounted on the top of the crossbeam 200 and positioned below the X-axis slide plate 551. The X-axis motor 553 is mounted on the X-axis slide plate 551, and its output end is connected to the X-axis gear 554. The X-axis gear 554 meshes with the X-axis rack 552. During operation, the X-axis motor 553 drives the X-axis gear 554 to rotate. Because the X-axis gear 554 meshes with the X-axis rack 552, the X-axis slide plate 551 is forced to slide along the X-axis of the crossbeam 200, thereby driving the copper nozzle pressure mechanism 500 to slide and fine-tune along the X-axis of the crossbeam 200.

[0044] like Figure 7 and Figure 9 As shown, the Y-axis fine-tuning assembly 560 includes a Y-axis lead screw 561, a Y-axis nut 562, and a Y-axis motor 563. The Y-axis lead screw 561 is rotatably mounted on the top of the copper nozzle assembly 530. The Y-axis nut 562 is sleeved on the Y-axis lead screw 561, and the top of the Y-axis nut 562 is connected to the bottom of the mounting plate 520. The Y-axis motor 563 is mounted on the top of the copper nozzle assembly 530, and its output end is connected to the Y-axis lead screw 561. During operation, the Y-axis motor 563 drives the Y-axis lead screw 561 to rotate, forcing the Y-axis lead screw 561 and the Y-axis nut 562 to move axially, thereby causing the copper nozzle assembly 530 to slide and fine-tune along the Y-axis of the mounting plate 520.

[0045] like Figure 1 , Figure 3 and Figure 4As shown, the two-dimensional motion mechanism 700 includes a lifting plate 710, a longitudinal transfer plate 720, a lifting drive assembly 730, and a longitudinal transfer drive assembly 740. Two lifting plates 710 are respectively installed at both ends of the crossbeam 200. The longitudinal transfer plate 720 is slidably installed on the inner side of the top of the frame 100, with one end of the longitudinal transfer plate 720 near the crossbeam 200 slidably connected to the lifting plate 710. The lifting drive assembly 730 is distributed on the crossbeam 200 and the lifting plate 710 to drive the lifting plate 710 to perform Z-axis movement along the longitudinal transfer plate 720. The longitudinal transfer drive assembly 740 is installed at the top of the frame 100 to drive the longitudinal transfer plate 720 to perform Y-axis movement along the frame 100. Specifically, the longitudinal transfer drive assembly 740 has a similar structure to the X-axis fine-tuning assembly 550, and will not be described again here.

[0046] like Figure 3 , Figure 4 and Figure 6 As shown, the lifting drive assembly 730 includes a lifting screw 731, a lifting nut 732, a steering gear 733, a synchronous shaft 734, and a lifting motor 735. The lifting screw 731 is rotatably mounted on the side of the lifting plate 710 away from the longitudinal transfer plate 720. The lifting nut 732 is sleeved on the lifting screw 731. The synchronous shaft 734 is rotatably mounted on the opposite outer side of the crossbeam 200. There are two synchronous shafts 734, which are spaced apart along the X direction. The opposite outer ends of the synchronous shafts 734 are respectively connected to the bottom end of the lifting screw 731 through the steering gear 733. The lifting motor 735 is mounted in the middle of the crossbeam 200. The output end of the lifting motor 735 is respectively connected to the opposite inner ends of the two synchronous shafts 734. One end of the lifting nut 732 passes through the square hole 711 opened on the lifting plate 710 and is connected to the longitudinal transfer plate 720. During operation, the lifting motor 735 drives the two synchronous shafts 734 to rotate synchronously, which in turn drives the two lifting screws 731 to rotate through the steering gear 733, forcing the lifting screws 731 and the lifting nut 732 to move axially, thereby causing the lifting plate 710 to slide along the longitudinal plate 720 in the Z direction.

[0047] like Figure 1 , Figure 12 and Figure 13As shown, the three-dimensional motion mechanism 800 includes a crossbeam 810, a Z-axis plate 820, a Y-axis plate 830, an X-axis plate 840, a Z-axis drive assembly 850, a Y-axis drive assembly 860, and an X-axis drive assembly 870. The crossbeam 810 is arranged parallel to each other between two crossbeams 200. There are two Z-axis plates 820, which are respectively installed at both ends of the crossbeam 810. The Y-axis plate 830 is slidably installed on the inner side of the top of the frame 100. The end of the Y-axis plate 830 near the crossbeam 810 is slidably connected to the Z-axis plate 820. There are two X-axis plates 840, which are respectively slidably installed at both ends of the crossbeam 810. The components are mounted on both sides of the crossbeam 810. A Z-axis drive assembly 850 is positioned between the Z-axis plate 820 and the Y-axis plate 830 to drive the Z-axis plate 820 to move along the Y-axis plate 830 in the Z direction. A Y-axis drive assembly 860 is mounted at the top of the frame 100 to drive the Y-axis plate 830 to move along the frame 100 in the Y direction. An X-axis drive assembly 870 is mounted at the top of the crossbeam 810 to drive the X-axis plate 840 to move along the crossbeam 810 in the X direction. A plate detection mechanism 600 is mounted on the side of the X-axis plate 840 away from the crossbeam 810. Specifically, the Y-axis drive assembly 860 and X-axis drive assembly 870 have similar structures to the X-axis fine-tuning assembly 550; the Z-axis drive assembly 850 has a similar structure to the Y-axis fine-tuning assembly 560.

[0048] During operation, the two-dimensional motion mechanism 700 drives two crossbeams 200 to press down on two rows of copper nozzles 533 in a stepping manner. When the robot 300 drives the welding mechanism 400 to weld one row of copper nozzles 533, the other crossbeam 200 presses down on the next row of copper nozzles 533 to be welded, thus achieving continuous welding.

[0049] like Figure 7 , Figures 9-11 As shown, the copper nozzle assembly 530 also includes a male connector 535, a female connector 536, a locking ring 537, and a stop lock 538. The male connector 535 is mounted on the top plate 531, and the female connector 536 is mounted on the tooling plate 532. The bottom end of the male connector 535 is pneumatically inserted into the female connector 536. The locking ring 537 is installed in the first through hole 5311 in the top plate 531, and the stop lock 538 is installed in the second through hole 5321 in the tooling plate 532. The top end of the stop lock 538 extends into the second through hole 5321, and the locking tongue at the top of the stop lock 538 engages with the locking ring 537. The design of the locking ring 537 and the stop lock 538 effectively prevents accidental drop of the tooling plate 532 due to manual button operation or power / gas outages, thereby avoiding the risk of short circuit in the battery cell. Specifically, the stop lock 538 is prior art, and its specific structure will not be described in detail here.

[0050] like Figure 10 and Figure 11As shown, the copper nozzle assembly 530 also includes two positioning pins 539, which are respectively installed diagonally at the bottom of the top plate 531. The positioning pins 539 are inserted into the positioning holes 5322 opened in the tooling plate 532. The cooperation between the positioning pins 539 and the positioning holes 5322 enables the precise assembly of the tooling plate 532 and the top plate 531.

[0051] like Figure 2 , Figure 14 and Figure 15 As shown, the flying welding device also includes a cutting and changing mechanism 900 and a lifting and positioning mechanism 1000. The cutting and changing mechanism 900 is located below the tooling plate 532 and is used for changing the tooling plate 532. The lifting and positioning mechanism 1000 is centrally located within the frame 100 and is located below the tooling plate 532 for lifting and positioning the cutting and changing mechanism 900. The cutting and changing mechanism 900 enables automatic changing of the copper nozzle 533, greatly improving changing efficiency.

[0052] like Figure 14 As shown, the Chopper changeover mechanism 900 includes a changeover bracket 910, an AGV trolley 920, a changeover seat 930, and impact pins 940. The AGV trolley 920 is installed at the bottom center of the changeover bracket 910 to pull the changeover bracket 910. Several changeover seats 930 are installed at the top of the changeover bracket 910 and are spaced apart along the width direction of the changeover bracket 910. Multiple impact pins 940 are installed on the changeover seats 930 and are spaced apart along the length direction of the changeover seats 930. Specifically, the changeover seats 930 are arranged in four rows, with multiple new tooling plates 532 placed on the outer rows of changeover seats 930 on both sides.

[0053] like Figure 15 As shown, the lifting and positioning mechanism 1000 includes a base frame 1010, a lifting component 1020, a positioning component 1030, a correction component 1040, and a guide component 1050. There are two base frames 1010, which are arranged parallel to each other along the Y direction. The lifting component 1020 is located in the middle of the two base frames 1010 and is used to lift the changing bracket 910. The positioning component 1030 is located at both ends of the two base frames 1010. The correction component 1040 is located in the middle of the two base frames 1010 and is located outside the lifting component 1020 for correcting the shape of the changing bracket 910. The guide component 1050 is located on the opposite inner sides of the two base frames 1010 for guiding the changing bracket 910.

[0054] like Figure 16As shown, the lifting assembly 1020 includes a ramp 1021, a connecting rod 1022, a lifting block 1023, a roller 1024, a universal seat 1025, and a lifting cylinder 1026. The ramp 1021 is slidably mounted on the base frame 1010. There are two ramps 1021, which are spaced apart along the X direction. The two ramps 1021 are connected by the connecting rod 1022. The lifting block 1023 is located above the ramp 1021 and is slidably connected to the upright frame 1027 on the base frame 1010. The roller 1024 is mounted on the bottom end of the lifting block 1023 and rolls with the ramp surface of the ramp 1021. The universal seat 1025 is mounted on the top end of the lifting block 1023. The cylinder body of the lifting cylinder 1026 is mounted in the middle of the base frame 1010, and the drive end of the lifting cylinder 1026 is connected to the connecting rod 1022. During lifting, the lifting cylinder 1026 drives the two ramp blocks 1021 to slide in the X direction through the connecting rod 1022, forcing the roller 1024 to roll on the ramp surface of the ramp block 1021, thereby driving the lifting block 1023 to rise, and the ball bearings in the universal seat 1025 contact the changing bracket 910 for lifting.

[0055] like Figure 16 As shown, the positioning assembly 1030 includes a stop cylinder 1031, a stop member 1032, a positioning cylinder 1033, and a clamp 1034. The cylinder body of the stop cylinder 1031 is mounted on one end of the base frame 1010, and the positioning cylinder 1033 is mounted on the other end of the base frame 1010. The stop member 1032 is connected to the drive end of the stop cylinder 1031, and the clamp 1034 is mounted on the drive end of the positioning cylinder 1033. After the changeover bracket 910 is pulled between the two base frames 1010, the stop cylinder 1031 drives the stop member 1032 to extend and block, and then the positioning cylinder 1033 drives the clamp 1034 to rotate, thereby positioning the changeover bracket 910.

[0056] like Figure 16 As shown, the correction assembly 1040 includes a column 1041, a support plate 1042, a base plate 1043, a side push block 1044, and a side push module 1045. Two columns 1041 are installed at intervals in the middle of the base frame 1010, and are positioned outside the lifting assembly 1020. The support plate 1042 is installed at the top of the column 1041, and the base plate 1043 is installed in the middle of the support plate 1042. The side push block 1044 is slidably installed at the top of the base plate 1043, and the side push module 1045 is installed on the base plate 1043. The drive end of the side push module 1045 is connected to the side push block 1044. After the changing bracket 910 is lifted into position by the lifting assembly 1020, the side push module 1045 drives the side push block 1044 to move towards the changing bracket 910, thus correcting the position of the changing bracket 910.

[0057] like Figure 16As shown, the guide assembly 1050 includes a guide plate 1051 and guide wheels 1052. The guide plate 1051 is installed on the inner side of the base frame 1010, and there are several guide wheels 1052 arranged along the length of the guide plate 1051.

[0058] During the changeover process, the AGV trolley 920 pulls the changeover bracket 910 between the two base frames 1010. The lifting and positioning mechanism 1000 lifts and positions the changeover bracket 910. The two crossbeams 200 move to the middle of the changeover bracket 910, above the two rows of changeover seats 930 in the middle. The copper nozzle assembly 530 moves down, and the impact pin 940 enters the second through hole 5321, unlocking the impact lock 538. The locking tongue of the impact lock 538 and the locking ring 537 are no longer locked. At the same time, the air supply between the male connector 535 and the female connector 536 is no longer interrupted. Pneumatically, the tooling plate 532 is lowered onto the changing seat 930. Then, the two crossbeams 200 move to the two sides of the changing bracket 910, that is, above the two outer rows of changing seats 930. The top plate 531 moves down to contact the new tooling plate 532. The locking tongue of the bump lock 538 engages with the locking ring 537. At the same time, the male connector 535 and the female connector 536 are pneumatically connected to complete the changing. The lifting and positioning mechanism 1000 drives the changing bracket 910 to reset. Finally, the AGV trolley 920 pulls the changing bracket 910 out of the frame 100.
