Description

Technical Field

Currently, most repair shops use manual adhesive application and handheld laser welding, separate equipment. This manual process is often unregulated and of relatively low quality, impacting the safety of the repaired battery.

[0033] In this embodiment, the welding assembly uses a galvanometer welding head and a welding nozzle fixed on the same plate. A compression spring buffers and compensates for product flatness errors, ensuring accurate welding focal length and reducing welding defects. The welding assembly 12 includes a welding slide plate 17 connected to the sliding plate of the X-axis servo module 4. A vertical welding module base plate 18 is connected to the welding slide plate 17. A first Z-axis servo module 19 is connected to the welding module base plate 18. A welding connecting plate 20 is connected to the sliding block of the first Z-axis servo module 19. A linear guide pair 21 is connected to the welding connecting plate 20. The linear guide pair 21 is slidably connected to a galvanometer fixing plate 22 via a slider. A welding limiting block 23 is connected to the top of the welding connecting plate 20. The galvanometer... A guide shaft 26 is connected to the top of the fixing plate 22. The upper end of the guide shaft 26 is connected to the welding limiting block 23. A compression spring 25 is fitted on the guide shaft 26. A galvanometer lens 26 is connected to the galvanometer fixing plate 22. An air knife 27 is connected to the galvanometer lens 26. A copper nozzle fixing plate 28 is connected to the bottom of the galvanometer fixing plate 22. A welding copper nozzle 29 is connected to the copper nozzle fixing plate 28. A first rib 16 is connected between the welding module base plate 18 and the welding slide plate 17. A second rib 30 is connected between the copper nozzle fixing plate 28 and the galvanometer fixing plate 22.

[0034] Among them, the welding components can achieve height error compensation, and the compression spring 25 can be automatically compressed, which can accommodate a product flatness error of 15mm.

[0035] In this embodiment, the glue application assembly 11 includes a glue application slide plate 37, which is connected to the sliding plate of the X-axis servo module 4. A vertical glue application module base plate 36 is connected to the glue application slide plate 37. A second Z-axis servo module 31 is connected to the glue application module base plate 36. A transition plate 32 is connected to the second Z-axis servo module 31 via a sliding block. A glue application head positioning plate 34 is connected to the bottom of the transition plate 32. A glue application head 33 is connected to the glue application head positioning plate 34. A third rib plate 35 is connected between the glue application head positioning plate 34 and the transition plate 32. A drag chain fixing sheet metal 38 connected to the second drag chain 6 is connected to the glue application slide plate 37.

[0036] In this embodiment, the trolley positioning assembly 14 includes a trolley column 40, which is connected to the ground by bolts 41. A trolley longitudinal beam is connected to the trolley column 40, a trolley guide plate 42 is connected to the trolley longitudinal beam, a guide wheel 43 is connected to the trolley guide plate 42, a trolley limiting plate 45 is connected to the end of the trolley longitudinal beam, and a positioning bolt 44 is connected to the trolley longitudinal beam.

[0037] In one embodiment, the trolley assembly 13 includes a trolley frame 46, with casters 47 connected to the bottom of the trolley frame 46 and stops 48 connected to the side of the trolley frame 46.

[0038] The working principle of this invention is as follows:

[0039] In practice, a forklift is used to manually load the trolley. The forklift lifts the trolley and pushes it into the trolley positioning mechanism. After the trolley is lowered, four positioning bolts support it, and the wheels are off the ground to ensure the flatness of the trolley's positioning. This prevents errors caused by uneven ground, which could affect gluing and welding. After the trolley is positioned, the trajectory program is manually edited point by point, followed by gluing or welding. Once the work is completed, the forklift is used to manually lift and remove the trolley, and new trolley components are loaded.

[0040] like Figure 5 As shown, the operator applies adhesive to the bottom of the battery tray 49 according to the working principle described above.

[0041] like Figure 6 As shown, the battery module 50 is placed on the car frame 46. The operating principle is the same as the specific work described above, and will not be repeated here. Welding is performed using the welding head assembly 12. During welding, the first Z-axis servo module 19 drives the welding copper nozzle 29 to press down and tighten the product.

[0042] This invention employs a large-format gantry structure with both horizontal and vertical dimensions, accommodating larger power battery pack sizes. It integrates adhesive coating and laser welding into a single composite process, resulting in low equipment cost and a small footprint. A trolley-style loading and unloading structure ensures rapid loading and unloading, improving efficiency. A galvanometer welding head and welding nozzle are fixed to the same plate, with a compression spring used to buffer and compensate for product flatness errors, ensuring accurate welding focal length and reducing welding defects.

[0043] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0044] In the description of this application, it should be noted that the terms "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use. They are used only for the convenience of describing this application and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0045] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or vertical, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0046] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "set up," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0047] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
