[0002] The battery liquid cooling plate is used for transferring heat generated in the battery working process to the cooling liquid flowing through the internal cooling channel of the battery liquid cooling plate through the direct or indirect contact between the battery core or module and the aluminum surface, so that high-efficiency heat dissipation is achieved. The design can quickly lead out the heat and prevent the battery temperature from being too high.

[0003] The surface of the battery liquid cooling plate has an oxide layer, and the oxide layer needs to be removed. In the prior art, a flow line is generally used to remove the oxide layer on different surfaces of the battery liquid cooling plate. However, for the long-strip-shaped battery liquid cooling plate, it is inconvenient to fix due to the too long length, and the general flow line cannot adapt to the long-strip-shaped battery liquid cooling plate, and the turning of the surface is inconvenient, which finally affects the removal efficiency of the oxide layer of the battery liquid cooling plate, that is, affects the roughening efficiency of the battery liquid cooling plate.

[0066] The beneficial effects are: the carrier module 01 can adapt to the long strip-shaped battery liquid cooling plate, the position of the upper end of the carrier module 01 relative to the lower end can be adjusted by the adjusting device 14, ensuring the synchronization rate of the upper end and the lower end of the battery liquid cooling plate, and improving the precision of subsequent laser roughening processing; the floating module 02 can prevent the upper end of the carrier module 01 from contacting the first annular line 11, ensuring that the carrier module 01 can slide smoothly on the first annular line 11 and the second annular line 12, and improving the transportation efficiency of the battery liquid cooling plate.

[0067] The first annular line 11 comprises: an upper guide rail line 111; an upper sliding seat 112, one end of the upper sliding seat 112 being slidably connected to the upper guide rail line 111; and an upper ring line 113, the upper ring line 113 being located above the upper guide rail line 111.

[0069] The number of the lower sliding seats 122 corresponds to the number of the upper sliding seats 112. One or more rollers j8 are arranged on the upper sliding seat 112 and the lower sliding seat 122 respectively. The rollers in the upper sliding seat 112 are connected to the upper guide rail line 111 and can slide on the upper guide rail line 111. The rollers in the lower sliding seat 122 are connected to the lower guide rail line 121 and can slide on the lower guide rail line 121.

[0070] Any two adjacent upper sliding seats 112 have the same spacing; any two adjacent lower sliding seats 122 have the same spacing.

[0072] The beneficial effects are that the staff can adjust the position of the upper ring line 113 in the x direction through the adjusting device 14, adjust the position of the upper slide 112 sliding on the upper guide rail line 111, and make the position of the lower slide 122 corresponding to the upper slide 112 on the lower guide rail line 121 consistent with the y direction of the upper slide 112, that is, the upper slide 112 and the lower slide 122 are collinear in the y direction, and the position of the upper slide 112 relative to the lower slide 122 is synchronized.

[0073] The synchronization module 15 includes a first transmission gear 151, a transmission rod 152, and a second transmission gear 153; the first transmission gear 151 is engaged on the lower guide rail line 121; the second transmission gear 153 is engaged on the upper guide rail line 111; and the two ends of the transmission rod 152 are respectively connected to the first transmission gear 151 and the second transmission gear 153.

[0078] The upper end of the carrier module 01 is provided with a fixed plate 011, and on the fixed plate 011, corresponding to the positions of the clamping grooves 026 in the first floating block, the second floating block 023, the third floating block 024, and the fourth floating block 025, respectively, a clamping piece 012 is arranged, and the clamping piece 012 can slide up and down in the clamping groove 026.

[0079] It should be noted that the first annular line 11 cannot be made completely parallel to the second annular line 12. Therefore, the height of the first annular line 11 relative to the second annular line 12 is not consistent at various positions. Therefore, the aforementioned inconsistency in height is compensated by the sliding of the card 012 up and down in the card slot 026.

[0080] In the embodiments of this application, the number of slots 026 on the first floating block, the second floating block 023, the third floating block 024, and the fourth floating block 025 is set to three, and the middle slot 026 of the three slots 026 engages with the card 012.

[0082] The first narrow-face roughening module 2 is located outside the annular transport module 1; the first dust extraction module 3 is located outside the annular transport module 1 and on one side of the first narrow-face roughening module 2, and is used to remove dust from the battery liquid cooling plate after it has been processed by the first narrow-face roughening module 2.

[0083] like Figure 9 As shown,

[0084] In terms of specific structure, the first narrow-faced texturing module 2 and the second narrow-faced texturing module 9 are basically the same, both including a first lifting device 21 and a first laser 22 connected to the first lifting device 21. The first lifting device 21 can drive the first laser 22 to slide up and down at the first lifting device 21.

[0091] It should be noted that in the embodiments of the present application, the third laser 52 on the second wide surface texturing module 5 and the third wide surface texturing module 6 has a large number of part structures at the lower end, so that the descending height of the third laser 52 on the second lifting device 51 is limited, i.e. the third laser 52 cannot act on the lower end face of the battery liquid cooling plate in the side direction, so the first wide surface texturing module 4 and the fourth wide surface texturing module 7 are provided to perform texturing processing on the lower end face of the battery liquid cooling plate in the side direction.

[0092] As Figure 13 shown,

[0093] In addition, a cleaning module 03 is arranged on one side of the second narrow surface texturing module 9, for cleaning the carrier module 01 and the battery liquid cooling plate on the carrier module 01, the cleaning module 03 including a bracket 031 and an air knife 032 connected to the bracket 031, a plurality of air knives 032 being arranged along the vertical direction of the bracket 031, and the air knives 032 are equidistantly arranged between the air knives 032, the air knives 032 being capable of being driven by an external gas supply device.
