Description

Technical Field

[0001] This utility model relates to the field of battery assembly technology, specifically to a peripheral welding integrated machine and a battery assembly system. Background Technology

[0002] With the development of the electronics industry, the application range of prismatic blade batteries is becoming increasingly wide. For assembly lines of prismatic blade batteries, improving assembly speed has become an industry consensus. However, traditional equipment has reached its design bottleneck and cannot meet the demand for increased production capacity of ultra-high-speed assembly lines.

[0003] Currently, traditional press-fitting and pre-spot welding integrated machines for prismatic battery assembly lines generally suffer from several pain points:

[0004] Firstly, most high-speed production lines in the industry achieve high capacity by stacking more workstations. At the same time, the transfer of products between workstations also becomes a limiting factor in assembly speed. In addition, the equipment occupies a large area, and the workstations and stations are numerous and densely distributed, making maintenance and repair inconvenient.

[0005] Secondly, the OEE of individual machines and the OEE of the entire line are low, the ramp-up cycle of the assembly line is particularly long, and the equipment under the traditional design concept has reached a bottleneck, making equipment iteration and innovation inevitable.

This enables high-speed and stable production in cell assembly. The ring-shaped assembly line design reduces the equipment's footprint. The use of rotating station components for transfer between stations provides maximum convenience for later maintenance and repair, while reducing the distance of personnel working and the number of on-site operators. This results in a significant improvement in the OEE of both individual machines and the entire production line.

At the same time, it reduces the distance of personnel working and the number of on-site operators, and achieves a significant improvement in the OEE of single equipment and the entire line.

[0022] The simplified design of the equipment mechanism modules in this application, combined with the integrated battery cell clamping fixture and magnetic levitation transportation technology, enables the processing of various functional modules, thereby significantly improving the OEE of single-machine equipment and the entire production line, reducing the ramp-up period for later equipment entry, and ensuring stable and efficient production.

[0023] This application introduces magnetic levitation transportation technology for the design of ultra-high-speed production lines. After gaining a deep understanding of the characteristics of battery cell assembly lines, it innovatively and disruptively redesigns existing battery cell assembly lines by adopting an integrated design of conveyor jig transportation and processing. This maximizes the high flexibility, intelligence, modularity, high speed, and high acceleration characteristics of the magnetic levitation system, achieving an extremely simplified design for ultra-high-speed assembly lines.

[0041] Reference Figure 1 and Figure 2 The magnetic levitation conveyor production line is arranged in a ring shape, with the ends connected. A cell clamping fixture (not shown in the figure) is installed above the magnetic levitation conveyor production line. The bottom of the cell clamping fixture is equipped with a magnetic levitation mover connected to the magnetic levitation conveyor production line. During operation, the magnetic levitation conveyor production line can drive the cell clamping fixture along the production line to pass through the above-mentioned processing stations in sequence for corresponding processing. The above-mentioned processing stations are arranged around or outside the magnetic levitation conveyor production line according to the conveying sequence. Fixture rotation station 1 (3), fixture rotation station 2 (13), fixture rotation station 3 (15), and fixture rotation station 4 (27) are respectively installed at the four corner positions of the ring-shaped magnetic levitation conveyor production line for the turning of the cell clamping fixture.

[0042] Reference Figure 1 and Figure 2Both the battery cell loading robot 1 and the battery cell unloading robot 26 are conventional loading and unloading robots in the field. This application has not made any improvements to them, so the detailed principles will not be described in detail. The battery cell loading robot 1 is installed at the battery cell loading station 2, and the battery cell unloading robot 26 is installed at the unloading station 25. The battery cell loading robot 1 can pick up and load the battery cells at the battery cell loading station 2 onto the battery cell clamping fixture.

[0043] Reference Figure 1 and Figure 2 The structures of the jig rotary stations 1-3, 2-13, 3-15, and 4-27 are the same. Taking jig rotary station 1-3 as an example, a base (not shown in the figure) is set at the bottom of the rotary station. A rotary motor is set at the bottom of the base, and a magnetic levitation conveyor line in the shape of "I" is set at the top of the base. When the jig is transported from the magnetic levitation conveyor line to jig rotary station 1-3, the rotation direction of the rotary motor at the bottom can be used to adjust the conveying direction of the battery clamping jig. The principle of the other jig rotary stations is the same as above.

[0044] Reference Figure 3 The structures of short-side addressing station 1 (4), long-side addressing station 1 (7), short-side addressing station 2 (11), and long-side addressing station 2 (17) are the same. Taking short-side addressing station 1 (4) as an example, its specific structure is introduced. The structures and principles of the other addressing stations are similar: Short-side addressing station 1 (4) includes a base 41, an addressing linear module 42, a vertical rod 43, a cover 44, an addressing camera 45, a horizontal rod 46, and a connecting rod 47. The addressing linear module 42 is installed on the top of the base 41. The moving direction of the addressing linear module 42 is consistent with the output direction of the magnetic levitation conveyor line. The vertical rod 43 is installed on the linear slide of the addressing linear module 42. The top of the vertical rod is connected to the horizontal rod 46 through the connecting rod 47. The horizontal rod 46 is set parallel to the magnetic levitation conveyor line at its bottom. Addressing cameras 45 are installed at both ends of the horizontal rod 46. The cover 44 is located directly below the addressing camera 45. The short-side addressing station and the long-side addressing station trace the welding path of the short or long side of the battery cell. Since each fixture may have a different shape, the position of the short or long side may be different. The corresponding coordinates are taken by a CCD addressing camera and sent to the system for position addressing.

[0045] Reference Figure 7 The short-side plasma cleaning station 15, long-side plasma cleaning station 18, short-side plasma cleaning station 212 and long-side plasma cleaning station 218 have the same structure and are used to clean the short and long sides of the battery, respectively. The specific structure of the short-side plasma cleaning station 15 is introduced as an example. The structure and principle of the other cleaning stations are the same.

[0046] The short-side plasma cleaning station 5 includes a horizontal linear module 51, a lifting module 52, a cleaning bracket 53, a connecting frame 54, a plasma cleaning gun 55, and a connecting plate 56. The bottom of the horizontal linear module 51 is supported by the cleaning bracket 53. The moving direction of the horizontal linear module 51 is consistent with the output direction of the magnetic levitation conveyor line. The linear slide of the horizontal linear module 51 is connected to the lifting module 52, and the lifting module 52 can be raised and lowered perpendicular to the output direction of the magnetic levitation conveyor line. The linear slide of the lifting module 52 is connected to the connecting plate 56 through the connecting frame 54. The plasma cleaning guns 55 are installed at both ends of the connecting plate 56. The outlet of the plasma cleaning gun 55 is directly facing the battery cell clamping fixture on the magnetic levitation conveyor line for plasma cleaning of the battery cells. The top of the plasma cleaning gun 55 is used to connect to the plasma cleaning machine.

[0047] Reference Figure 3 The short side welding station 16, long side welding station 10, short side welding station 26 and long side welding station 20 have the same structure and are used to weld the two short sides and two long sides of the battery, respectively. The specific structure of the short side welding station 16 is introduced as an example. The structure and principle of the other welding stations are the same.

[0048] The short-side welding station 6 includes a welding nozzle 61, a Z-axis lifting module 62, a Y-axis linear module 63, an X-axis linear module 64, and a support column 65. The bottom of the X-axis linear module 64 is supported by the support column 65. The movement direction of the X-axis linear module 64 is consistent with the output direction of the magnetic levitation conveyor line. The linear slide of the X-axis linear module 64 is connected to the Y-axis linear module 63, and the movement direction of the Y-axis linear module 63 is perpendicular to the movement direction of the X-axis linear module 64. The linear slide of the Y-axis linear module 63 is connected to the Z-axis lifting module 62, and the linear slide of the Z-axis lifting module 62 is connected to the welding nozzle 61. The welding nozzle 61 is located above the cell clamping fixture on the magnetic levitation conveyor line. The position of the welding nozzle 61 can be adjusted by the Z-axis lifting module 62, the Y-axis linear module 63, and the X-axis linear module 64 so that it is directly facing the short or long side of the cell to facilitate precise welding.

[0049] Reference Figure 5 The long-side welding inspection station 21 includes a first inspection profiler 211, a second inspection profiler 212, and a support frame 213. The first inspection profiler 211 and the second inspection profiler 212 are mounted on the support frame 213 and are located directly above the magnetic levitation conveyor production line. This application provides two sets of inspection profilers, which can simultaneously inspect the long sides of two sets of battery cells, improving efficiency by 50%. Of course, three or more sets can also be set, depending on the actual situation. This application only provides one implementation direction.

[0050] The short side welding inspection station 22 also uses a profilometer for inspection, and the principle is the same as that of the long side welding inspection station 21. It also has two sets of profilometers, which can simultaneously inspect the two short side profiles of the same cell.

[0051] Reference Figure 4 The long-side rolling station 23 includes a rolling support 231, rolling rollers 232, and a rolling Z-axis module 233. The rolling Z-axis module 233 is installed on one side of the rolling support 231. The rolling Z-axis module 233 is a linear module, and its linear slide is connected to the rolling support 231. That is, the rolling Z-axis module 233 can drive the rolling support 231 to move up and down in the vertical direction. Both ends of the rolling support 231 are equipped with retractable rollers for rolling the long side of the battery cell.

[0052] Example 2

[0053] This embodiment also discloses a battery assembly system, including the peripheral welding integrated machine in Embodiment 1.

[0054] The specific operating principle of this application is as follows:

[0055] First, the battery cell loading robot 1 picks up battery cells from the logistics line and places them onto the battery cell clamping fixture on the magnetic levitation conveyor line at the battery cell loading station 2. Then, driven by the magnetic levitation conveyor line, the battery cell clamping fixture is moved to the fixture rotation station 3 for turning. After that, it enters the short side addressing station 4 for CCD addressing of the welding trajectory of the first short side of the battery cell. Since each fixture may have a different shape, the position of the short side may be different. The corresponding coordinates are captured by CCD and sent to the system for accurate addressing. After addressing, it enters the short side plasma cleaning station 5 for plasma cleaning of the first short side. After plasma cleaning, it enters the short side welding station 6 for welding of the first short side of the battery cell. Welding is carried out while the product is running in the fixture.

[0056] After the first short side welding is completed, the cell is moved to the long side addressing station 7 by the magnetic levitation conveyor line for CCD addressing of the first long side. After addressing, it enters the long side plasma cleaning station 8 for plasma cleaning of the first long side. After plasma cleaning, it enters the reversing station 9, where the cell clamping fixture is reversed. The reversal here is performed according to the needs of the production line and the cell. If no reversal is required, no reversal is needed. Then, the cell continues to be moved to the long side welding station 10 by the magnetic levitation conveyor line for follow-up welding of the first long side. At this time, the first short side and the first long side have completed addressing, plasma cleaning and welding. Then, the addressing, plasma cleaning and welding of the other short side and long side are performed.

[0057] Then, driven by the magnetic levitation conveyor line, it continues to move to the short side addressing station 211 for CCD addressing of the second short side. After addressing is completed, it enters the short side plasma cleaning station 22 for plasma cleaning of the second short side. Then, it enters the fixture rotation station 23 for turning the magnetic levitation conveyor line. Then, it continues to move to the reversing station 24, and under the action of the reversing station 24, the cell clamping fixture is reversed. The reversal here is performed according to the needs of the production line and the cell. If no reversal is required, no reversal is required. Then, driven by the magnetic levitation conveyor line, it continues to move to the fixture rotation station 35 for turning the magnetic levitation conveyor line. Then, it enters the short side welding station 26 for follow-up welding of the second short side.

[0058] After the second short side welding is completed, the cell is moved to the long side addressing station 2 (17) by the magnetic levitation conveyor line for CCD addressing of the second long side. After addressing, it enters the long side plasma cleaning station 2 (18) for plasma cleaning of the second long side. After plasma cleaning, it enters the reversing station 3 (19) for reversing the cell clamping fixture. The reversing here is based on the needs of the production line and the cell. If no reversing is required, it is not necessary. Then, it continues to be moved to the long side welding station 2 (20) by the magnetic levitation conveyor line for follow-up welding of the second long side of the cell. After the second long side welding is completed, the cell enters the long side welding station in sequence. The inspection station 21 and the short side welding inspection station 22 monitor the 3D contour after welding. Then, the long side rolling station 23 rolls and shapes the long side of the welded battery cell. The long side is then rolled. The cells then enter the reversing station 24 to reverse the direction of the fixture and return it to its initial state (reset). The cells then enter the battery cell unloading station 25 to unlock and unload the processed cells. The battery cell unloading robot 26 unloads the processed cells onto the logistics line. Finally, the empty fixture continues to move into the fixture rotation station 27 to turn. The empty fixture then returns to the battery cell loading station 2 to start the next round of processing. This cycle repeats continuously.

[0059] It should be noted that in the initial state, the fixture moves with the first long side in the forward direction. After completing the welding process of the first long side, it can be rotated 90 degrees by reversing station 1 to move with the short side in the forward direction. After completing the welding process of the first short side, it can be rotated 90 degrees by reversing station 2 to move with the second long side in the forward direction. After completing the welding process of the second long side, it can be rotated 90 degrees by reversing station 3 to move with the second short side in the forward direction. After completing the welding process of the second long side, it can be rotated 90 degrees by reversing station 4 to move with the first long side in the forward direction back to the initial state. The reversing stations 1, 2, 3, and 4 have the same structure. A rotary motor can be installed inside the battery cell clamping fixture to realize the rotation of the fixture. This application does not limit this.

[0060] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
