Adjusting-calibrating-positioning method for PC board boring needle ringer

Abstract

This invention relates to a calibration and location method for PC board drill pin collar including: sticking a drill pin with a collar on a base for the drill, utilizing a side face CCD image generator to set a quasi-height above the drill base to let the vertical distance from the quasi-height to the top surface of the base equal to the standard collaring height of the collar, utilizing a ring squeezing piece to make the collar bottom to closely adhere to the top of the base and locate it, then using a lifter to push the pin till the needle part arrives at the quasi-position to avoid collide by the pin needles or broken so as to increase the collaring efficiency, accuracy and quality for drill pins.

Description

1. Technical field [0001] The invention relates to a method for adjusting drilling equipment, in particular to a method for adjusting, calibrating and positioning the collar of a drill pin on a PC board that has deviated from the height of the standard upper ring, and readjusting and positioning the collar of the PC board drill pin at the height of the standard upper ring. 2. Background technology [0002] Most of the existing PC board drilling preparation processes are completed by using drilling equipment to automatically grab the drill needle and perform boring processing. One, therefore, how to effectively control the machining depth and precision of the drilling equipment during boring and drilling is an important technical issue. [0003] In order to enable drilling equipment to perform high-precision drilling operations more effectively, micro-diameter drills for drilling PC boards are currently provided, such as figure 1 As shown, a collar 2 is sheathed at the prede...

Problems solved by technology

[0006] The above-mentioned existing collar adjustment calibration positioning means is to utilize the distance between the calibration collar 2 items 2' to the quasi-position height f of the CCD image visual device, and then add the predetermined collar thickness value s', as the collar thickness The standard height of the upper ring, this technical means and working principle, under the condition of the same ring thickness value, can achieve the implementation effect of adjusting the calibration positioning, however, if image 3 As shown, when the thickness value of the collar 2 is different, the actual positioning height h' of the collar will be different from the standard upper ring height h; in addition, in fact, the industry currently provides micro-diameter drills for PC board drilling The actual thickness of the collar used for nesting will be slightly thicker or thinner depending on the manufacturer. This situation often causes the drill bit to be automatically detected because it cannot be successfully obtained by the CCD image vision device. The focus position of the drill edge image is troubled by being listed as a defective product
