Perforating device

Abstract

A punching device is provided to improve the productivity in an image processing and a punching process of a high speed and a high accuracy. A guiding device(c2) of an optical system toward a camera body is swung centering the camera body. Reflecting portions(9a,9b) are installed in the guiding device of the optical system to reflect an image of a projected photographed portion. Thereby, the camera photographs by moving in a high speed and the shaking or the inclination of the image by a vibration are not generated. Therefore, an image processing and a punching process are performed with a high accuracy in a short time. By photographing the photographed portion by swing, the punching efficiency and the productivity are improved.

Description

technical field [0001] The present invention relates to a punching device for punching various workpieces such as printed circuit boards, thin-walled substrates, and ceramic printed circuit boards. Background technique [0002] Such a punching device includes a camera unit that captures a point such as a marker. [0003] As a specific example of the punching device, there is a structure in which a punch and a camera unit opposite to the punch are provided at the shooting point, and a punching mechanism coaxial with the punch and the lens and capable of swinging is formed between the punch and the lens of the camera unit ( For example, Patent Document 1 (refer to Japanese Patent No. 2561059 (page 1, first figure))); the punch and die of the punching unit and the camera unit along the A structure that oscillates in the horizontal direction (for example, Patent Document 2 (see Japanese Patent No. 2851001 (page 1, FIG. 2 )) and the like. [0004] In addition, there is also a s...

Problems solved by technology

[0007] However, in the piercing device of the swing piercing method in Patent Document 1, in order to swing the heavy piercing mechanism, there is almost no vibration in the movement when moving to the same axis as the die in Patent Document 3, and more precision is required. There is still room for improvement in high perforation processing

[0008] In this regard, the punching device of the swinging camera method in Patent Document 2 is considered to be suitable for punching requiring high precision because the camera unit is small in size and light in weight. Due to the durability of the unit, image processing during alignment cannot be performed with high precision due to focal shift or image distortion due to vibration, and it is not particularly suitable for punching that requires high precision.

[0009] In addition, when there are a plurality of imaging points for aligning the perforated portions, there is a problem in Patent Documents 1 to 3 that each point must be moved directly below the camera unit, which takes tact time for alignment.
