Description

Spindle, Router Apparatus and Cutting Bit The present invention relates to a spindle, a router device, and a cutting bit used for cutting a substrate. Generally, in order to improve production efficiency in a substrate manufacturing process such as a printed circuit board, a routing process can be performed in which a continuous array board, in which multiple printed circuit boards are arranged on a single panel, is cut and separated into multiple individual printed circuit boards using a substrate cutting device such as a router device. In the case of such router devices, a substrate is cut with a cutting bit mounted on one end of the spindle. The cutting portion of the cutting bit used to cut the substrate is a part that protrudes a certain length from one end of the spindle. When the service life of the cutting portion is exhausted, it must be replaced with a new cutting bit. However, due to the limited length of the cutting portion, the service life of the cutting bit is short, resulting in a problem of a short replacement cycle. FIG. 1 is an exemplary diagram showing a router device according to one embodiment of the present invention. FIG. 2 is an exemplary diagram showing a spindle used in a router device according to one embodiment of the present invention. FIG. 3 is an exemplary diagram showing a cutting bit according to one embodiment of the present invention. FIG. 4 is an exemplary diagram showing the fastening structure of a spindle support head and a cutting bit according to one embodiment of the present invention. FIGS. 5 to 9 are exemplary diagrams illustrating the operation process of a router device. FIG. 10 is an exemplary diagram showing a cutting bit according to another embodiment of the present invention. FIG. 11 is an illustrative diagram showing a cutting bit according to another embodiment of the present invention. Hereinafter, preferred embodiments of the present invention will be described as follows with reference to the attached drawings. FIG. 1 is an exemplary diagram showing a router device according to an embodiment of the present invention, FIG. 2 is an exemplary diagram showing a spindle used in a router device according to an embodiment of the present invention, FIG. 3 is an exemplary diagram showing a cutting bit according to an embodiment of the present invention, and FIG. 4 is an exemplary diagram showing a fastening structure between a support head of a spindle and a cutting bit according to an embodiment of the present invention. Referring to FIGS. 1 to 3, a router device according to one embodiment of the present invention may include a spindle (100) used to cut a substrate (B), a control area (A2), and a transfer robot (R). The above substrate (B) may have a plurality of unit substrates (UB) arranged thereon. For example, the above substrate (B) may be a series of printed circuit boards in which a plurality of unit printed circuit boards are arranged. A bridge (not shown) may be positioned between adjacent plurality of unit substrates (UB), and the substrate (B) may be cut along the bridge (not shown) using a cutting bit (200) to be described later.
