Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a pin punching device that is used for both a single-layer substrate and a multilayer substrate, and is a multi-layer printed circuit board that is processed by an NC machine, that is, an automatic machine of a numerical control system. , And various other printed circuit boards (hereinafter simply referred to as “boards”)
When setting one or more sheets at a predetermined position on an automatic machine, a guide pin is used to position the holes for driving the pins and align the hole positions of the multi-layer board with pre-drilled holes. Can be performed by a single device.

[Conventional technology]

Generally, when mounting various substrates on an automatic machine, positioning pins are set up near the opposite side edges of the substrate and inserted into holes on the other side to perform positioning without misalignment. Conventionally, positioning pins are provided on a substrate, regardless of whether it is a double-sided substrate or a single-sided substrate, and a hole for driving the base of the positioning pin is formed. After the guide pins are inserted through the pin holes to align the holes of the plurality of substrates, positioning pins are driven in, whereby the circuits of the stacked substrates are properly positioned.

[Problems to be solved by the invention]

However, in the above-mentioned double-sided board or single-sided board, a hole for driving the base of the guide pin is formed,
In the case of multi-layered boards, in order to insert the pins into the pre-opened pin holes and align the hole positions of multiple boards, processing is performed by dedicated machines or manuals that are suitable for each application. I was

Therefore, there have been problems such as poor workability in positioning the hole for pin driving and alignment of the processed pin hole, taking up space, and increasing the cost.

[Means for solving the problem]

Therefore, the present invention is provided to solve the problems of the prior art and to achieve the object of the invention. In a pin punching device that is used as a double-sided or single-sided board and a multi-layer board, a plurality or a plurality of pins are provided at predetermined positions on a work table. A single drilling hole is drilled, a pin punching machine is provided immediately above the drilling hole, and a pin drilling machine is arranged immediately below the drilling hole, and at a predetermined distance from the drilling machine. , The hole guide pin inserter is connected, the hole puncher / guide pin inserter is movably hooked to the guide rail via a horizontal moving mechanism, and the switching mechanism is used for the pin puncher. Alternatively, the guide pin insertion machine can be moved to the position of the drill through hole and stopped.

[Action]

The operation based on the above means will be described. First, in the case of a single-layer board, regardless of whether it is a single-sided board or a double-sided board, the positions where holes are to be drilled on both sides or on one side are aligned with the respective drill holes on the work table, and then the clamps on the pin driving machine side Press and fix with. Next, the pin drilling machine disposed immediately below the work table is advanced to the drill through hole position along the guide rail by the horizontal moving mechanism, and then stopped. Subsequently, by the operation of the advance / retreat mechanism of the pin drilling machine, the drill bit advances upward, and is inserted into the drill through hole, and then a hole is formed in the substrate. When the drilling is completed, the drill bit is lowered and returns to the original position. When the return is completed,
When the pin driver directly above the worktable is driven, the base of the pin is driven into the hole that has been drilled beforehand and stands up.

Next, in the case of a multilayer board, the pin drilling machine is horizontally moved in a direction away from the drilling hole position with the drill bit retreated downward, and at the same time, the guide pin inserting machine is moved by the guide pin inserting machine. And stops at the drill through hole position.

Next, by the operation of the advance / retreat mechanism of the guide pin insertion machine, the guide pin advances upward, is inserted into the drill through hole, and projects upward from the work table surface. Then, in the protruding state, the pin holes of the multilayer board are fitted to the guide pins projecting from the work table surface to perform positioning. Then, it is fixed on a work table with a clamp.
Subsequently, after the guide pin is lowered and returned to the original position, when the pin driving machine directly above the work table is driven, a positioning pin is supplied from the pin driving machine side, and the end thereof is previously opened. It is driven into the pin hole and is erected.
