Mechanism for producing end edge guide angle of golden finger on circuit board

Abstract

A mechanism used for preparing guide angle of end edge on gold finger at circuit board consists of a frame, a tool being set on frame and being set with a numbers of openings, a platform being set on frame near a side of tool and being set with a circuit board and a driver to move platform to tool to let said openings correspond to gold finger on circuit board, a cutter being set on frame near to another side of tool and being used to cut tail end of gold finger at corresponding locations of said openings for cutting out a vertical slope guide angle at tail end of gold finger.

Description

technical field [0001] The invention relates to a mechanism for making the edge chamfering of gold fingers on a circuit board, in particular to a mechanism that can eliminate the tolerance of a circuit board, so that the end edges of the gold fingers on the circuit board can be cut into neat vertical The mechanism of the inclined chamfer in the direction of the direction. Background technique [0002] Generally, after the circuit is printed on the existing circuit board, it will be cut at the appropriate position of the circuit board according to the factory requirements of the product. The circuit board will have burrs at the cut position, which will cause the circuit board to short-circuit, etc. Failure, causing the circuit board to be damaged and unusable, especially after the circuit board is cut at the position with gold fingers, a small piece of conductive wire will remain at the end of these gold fingers, and these conductive wires may overlap to the phase. The adjac...

Problems solved by technology

[0005] But the interface is only conveyed by the upper and lower conveyor belts. When the interface is subjected to a resistance, the interface will be deflected, so that the cutter cannot cut the correct lead angle on the interface, and then the metal of the interface will be cut. Finger surfaces of varying lengths, such as figure 1 As shown, furthermore, the interface cannot be pressed flat by the upper and lower conveyor belts, making the interface uneven, especially where the interface is provided with gold fingers. When the knife cuts the gold of the interface At the end of the finger, the cutting depth of the tool on the interface will be different, so that after the interface is cut, the golden finger will be uneven and of different lengths, such as figure 1 As shown, in this way, the interface will not be able to comply with the factory regulations, resulting in loss of manufacturing costs for the industry
