Description

Technical Field

[0001] This utility model belongs to the field of copper electrode plate flattening technology, and particularly relates to a flattening device for copper electrode plates. Background Technology

[0002] In precision manufacturing fields such as semiconductor leadframes, electronic connectors, and electroplated anodes, copper electrode plates are core functional components, and their flatness directly determines the assembly accuracy and electrical performance of subsequent processes. Due to uneven distribution of internal stress and springback effect during metal stamping, electrode sheets are prone to complex warping shapes such as edge curling and wavy deformation. By eliminating residual stress and reshaping the planar reference through flattening processes, product yield can be significantly improved, providing the necessary foundation for micron-level processing.

[0003] Existing flattening devices rely on manually controlled spring clamping mechanisms and screw drive systems, resulting in a significant trade-off between efficiency and accuracy. Operators must repeatedly turn the screw to drive the pressure plate downwards, while simultaneously observing the fluctuations of the dial indicator to determine the horizontal state. This process has three major drawbacks: firstly, manual adjustment makes it difficult to ensure that the pressing component moves horizontally downwards, easily causing indentations on the copper surface; secondly, visual judgment is subject to subjective errors.

[0035] The driving component 1 drives the first bevel gear transmission box 2, which in turn drives the two second bevel gear transmission boxes 3, and then the two second bevel gear transmission boxes 3 drive the screw jack 4 to move.

[0036] Further optimization of the scheme: the micro-compensation component includes a connecting plate 6, the top of the connecting plate 6 is rotatably connected to the bottom end of the lead screw 5, and a piezoelectric actuator 7 is fixedly installed at the bottom of the connecting plate 6.

[0042] The scheme is further optimized. The frame component includes a top plate 13, and side plates 14 are fixed to both sides of the top plate 13. The side plates 14 are parallel and symmetrically arranged. A bottom plate 15 is fixed between the bottoms of the side plates 14.

[0043] The support assembly and the pressure roller 12 below the pressure plate 10 work together to flatten the copper electrode plate.

[0044] The scheme is further optimized. The support assembly includes several support rollers 16. The two ends of the support rollers 16 are rotatably connected to the two side plates 14 respectively. The support rollers 16 and the pressure rollers 12 are arranged in a one-to-one correspondence.

[0051] The distance values ​​at different positions of the lower pressure plate 10 can be obtained by the laser range sensor 23, thereby determining whether the lower pressure plate 10 is in a horizontal state.

[0052] During use, an external drive mechanism first provides pulling and dragging force to the strip-shaped copper electrode plate, such as a winding machine or other equipment that can perform this function.

[0053] Then, the drive unit 1 can be a motor. The drive unit 1 drives the first bevel gear transmission box 2 and the second bevel gear transmission box 3 to indirectly drive the screw 5 on the screw jack 4 to press down the lower pressure plate 10, completing the coarse adjustment and quick positioning.
