Abstract
The utility model relates to a cutter special for a printed circuit board, which is used for slotting of printed circuit boards and comprises a base board (1) and a plurality of blades (2), wherein the base board (1) is in an annular structure, the blades (2) are distributed on the peripheral surface of the base board (1), the cross sections of the blades (2) are triangular, the triangular bottom surfaces of the blades (2) are arranged on the peripheral surface of the base board (1), and the included angle at the top of each of the blades (2) is 12-18 degrees. The cutter special for the printed circuit board is good in cutting effect and higher in smoothness of cut surfaces.
Description
(1) technical field
The utility model relates to a kind of printed circuit board (PCB) dedicated tool, is used for printed circuit board (PCB) is slotted.
(2) background technology
Printed circuit board (PCB) is widely used in electronic applications, when printed circuit board, normally prints out some identical circuit boards on large-sized sheet material, utilizes the groove cutter that it is carried out the V-shaped groove cutting subsequently, so that the client is cut apart it.Conventional groove cutter, its top angle is 30～45 °, so big angle, though the wearability of groove cutter is better, but for printed circuit board (PCB), because angle is excessive, cutting effect is bad, cause otch that circuit board injustice behind the burr is arranged, influence is stacked and carrying, and after the chip surface increasing, cutting output increases, it is big that the smear metal heat becomes, and produces environmental pollution.
(3) summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of good cutting effect and the higher printed circuit board (PCB) dedicated tool of cutting surface smoothness are provided.
The purpose of this utility model is achieved in that a kind of printed circuit board (PCB) dedicated tool, described cutter includes substrate and blade, described substrate is a loop configuration, described some blades are distributed on the outer edge surface of substrate, the cross section that described blade is is a triangle, the triangle bottom surface of described blade is arranged on the outer edge surface of substrate, and the top angle theta of described blade is 12～18 °.
The beneficial effects of the utility model are:
Because the top angle of the utility model cutter is 12～18 °, than conventional cutter, utilizes low-angle cutting, can guarantee cutting effect preferably, make that the cutting surface smoothness is better.
(4) description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model blade joint schematic diagram.
Among the figure:
(5) specific embodiment
Referring to Fig. 1, the utility model relates to a kind of printed circuit board (PCB) dedicated tool, described cutter includes substrate 1 and blade 2, described substrate 1 is a loop configuration, described some blades 2 are distributed on the outer edge surface of substrate 1, and the cross section that described blade 2 is is a triangle, and the triangle bottom surface of described blade 2 is arranged on the outer edge surface of substrate 1, the top angle theta of described blade 2 is 12～18 °, as shown in Figure 2.
Claims (1)
1. printed circuit board (PCB) dedicated tool, it is characterized in that: described cutter includes substrate (1) and blade (2), described substrate (1) is a loop configuration, described some blades (2) are distributed on the outer edge surface of substrate (1), the cross section that described blade (2) is is a triangle, the triangle bottom surface of described blade (2) is arranged on the outer edge surface of substrate (1), and the top angle theta of described blade (2) is 12～18 °.
