[0035] The scraping device adopts the design form of an executive manipulator 1, a pressure contact structure 2 and a glue discharging structure 3. The executive manipulator 1 is used as a reference. The executive manipulator 1 has two intersecting X-directions, Y-directions and Z-directions. The executive manipulator 1 is used as a driving mechanism to drive its executive end 10 to move relative to the plastic isolation board 4. The executive manipulator 1 drives the executive end 10 to perform a scraping operation on a specific position of the plastic isolation board 4, which is convenient for pasting and fixing the FPC flexible circuit board and the aluminum target on the plastic isolation board, thereby completing the assembly process of the CCS integrated busbar. The FPC flexible circuit board is used to collect information such as the temperature and voltage of the battery, and the copper-aluminum busbar is a conductive part used to realize high-voltage series-parallel connection between the battery cells.

[0036] In this embodiment, the X direction refers to the length direction of the plastic isolation board 4, the Y direction refers to the width direction of the plastic isolation board 4, and the Z direction refers to the direction perpendicular to the board surface of the plastic isolation board 4. It should be noted that in other embodiments, the X direction and the Y direction are not limited to the length direction and the width direction of the plastic isolation board 4. The X direction and the Y direction intersect vertically in the board surface of the plastic isolation board 4, and the Z direction can be set perpendicular to the board surface direction of the plastic isolation board 4. In addition, the angle between the X direction and the Y direction in the range of 80° to 90° falls within the protection scope defined by "vertical" in the present utility model.

[0039] In this embodiment, a Z-direction guide rail 24 is provided on the base 21, and the slider 22 is movably mounted on the Z-direction guide rail 24. The buffer 23 is a cylindrical compression spring, and the expansion and contraction direction of the cylindrical compression spring is arranged to extend along the Z direction. The slider 22 is movably mounted on the base 21 through the Z-direction guide rail 24, which ensures the Z-direction movement accuracy of the slider 22 and the rubber scraper 32. Moreover, the cylindrical compression spring can generate a stable elastic pressure on the slider 22, ensuring that the rubber scraper 32 effectively contacts the plastic isolation plate 4 and evenly applies the glue. In order to meet different usage requirements, the buffer is not limited to the cylindrical compression spring.

When the notch 325 of the shaping sheet 323 partially overlaps with the glue flow groove 320 of the fixed block 321, a glue outlet 324 is formed for the glue liquid to be discharged smoothly. By changing the thickness of the shaping sheet 323 and the width of the notch 325, the glue discharge speed, the glue scraping thickness, the glue scraping width and other parameters can be adjusted.
