To achieve the above object, the present application mainly comprises: the circuit board cutting mechanism comprises a driving unit, a base, a first cutter and a second cutter.

In a preferred embodiment, the driving unit is a motor mechanism disposed beside the base.

In a preferred embodiment, the base is used for installing the driving unit, the first tool and the second tool.

In a preferred embodiment, the first tool is disposed beside the base, and is preferably disposed in an upright manner, but not limited thereto.

In a preferred embodiment, the second tool is disposed beside the base, and is preferably arranged in an upright manner, but not limited thereto; the second cutter is positioned below the first cutter.

In a preferred embodiment, the first tool and the second tool have different diameters, one having a relatively larger diameter and the other having a relatively smaller diameter.

In a preferred embodiment, the diameter of the first tool is relatively larger than the diameter of the second tool.

In a preferred embodiment, the diameter of the first tool is relatively smaller than the diameter of the second tool.

In a preferred embodiment, the first cutting tool has a first cutting edge on its edge.

In a preferred embodiment, the second cutting tool has a second cutting edge disposed on the rim thereof.

In a preferred embodiment, the rotation speeds of the first and second tools are preferably equal.

In a preferred embodiment, the first cutting edge and the second cutting edge are respectively located at the left side and the right side of a central vertical line formed between the first cutting edge and the second cutting edge in the vertical direction, and are in an abutting or slightly abutting relationship with each other.

In a preferred embodiment, a pressing unit is disposed adjacent to a side edge of the base for pressing the circuit board.

The utility model has the advantages that:

the utility model discloses the diameter configuration relation of two cutters in the mechanism is cut in the utilization change, the rim collapse phenomenon among the prior art can be effectively solved. Therefore, when the circuit board is cut, compared with the prior art, the process of the roll cutting operation has stable cutting structure, can effectively reduce the collapse of the board edge and greatly improve the cutting flatness and quality of the board edge. Through the realization of aforementioned main objective, this application indirect can make the defective rate of processing very reduce, and then reduce unnecessary consume, create the profit.

Detailed Description

Now, the structure of the circuit board cutting mechanism for cutters with different diameters of the present invention is composed, and the functions that can be generated by the mechanism are described in detail below with reference to the accompanying drawings.

Referring to fig. 1 and 2, the present application provides a circuit board cutting mechanism for cutting tools with different diameters, which includes a driving unit 1, a base 2, a first tool 3 and a second tool 4. Wherein, the driving unit 1 is a motor mechanism, which is arranged beside the base 2; the base 2 is used for arranging the driving unit 1, the first cutter 3 and the second cutter 4; the first cutter 3 is arranged beside the base 2 and is preferably arranged in a vertical shape; the second cutter 4 is arranged beside the base 2 and is preferably arranged in an upright shape; the second tool 4 is located relatively below the first tool 3; the first tool 3 and the second tool 4 have different diameters, one of which has a relatively larger diameter and the other of which has a relatively smaller diameter, in this embodiment, the diameter of the first tool 3 is relatively slightly larger than that of the second tool 4, and of course, the diameter of the first tool 3 may also be relatively slightly smaller than that of the second tool 4; the edge of the first cutter 3 is provided with a first blade 31, and the edge of the second cutter 4 is provided with a second blade 41; the first blade 31 and the second blade 41 are respectively located on the left and right sides of a central vertical line (as shown in fig. 2) formed between the first blade 31 and the second blade 41 in the vertical direction, and are in almost abutting or slightly abutting relation with each other.

As shown in fig. 3, a pressing unit 5 is disposed adjacent to the edge of the base 2, and can be used to clamp a circuit board 9.

In the application, a circuit board 9 is sent to a preset position, and the pressing unit 5 is used for clamping and positioning the circuit board 9 so as to avoid sliding or displacement (figure 3); then, the driving unit 1 is operated, the first cutter 3 and the second cutter 4 are in a rotating state, and the first cutter 3 and the second cutter 4 can perform rolling shearing operation relative to the circuit board 9 by matching with the displacement of the base 2 relative to the circuit board 9; because the first cutter 3 of this application sets for different diameters for second cutter 4, and sets for equally because of the rotational speed of this first cutter 3 and second cutter 4, consequently the operation of roller shear is laborsaving than current structure, when carrying out the cutting of thicker circuit board 9 very much, the process of roller shear operation is fairly stable, can effectively reduce the problem that the board limit collapsed among the prior art really, promotes the board limit and cuts roughness and quality by a wide margin.

Although the present invention has been described with reference to the foregoing embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention. The foregoing description of the preferred embodiments of the present application is provided for the purpose of illustration only, and not for the purpose of limitation, as defined by the appended claims.
