Abstract

The present application provides a position alignment device for an inner layer PCB board and relates to the field of PCB board processing. It comprises a pre-position fixing mechanism and an X-ray identification mechanism. The pre-position fixing mechanism is used to align the PCB board in the middle position. It includes a support frame installed in a feeding transport unit. A position fixing base that slides at an arbitrary angle along the horizontal direction is installed at the top of the support frame. A material plate is mounted on the top end of the position fixing base. A set of first adsorption members is mounted in the middle of the material plate. The X-ray identification mechanism is installed in a housing and includes support plates located on both sides of the middle of the feeding transport unit. An X-ray camera module facing the material plate is vertically installed on the support plates. The present application performs position information analysis by reading the position fixing target and direction indicator of the inner layer of the PCB board through the X-ray camera module. Furthermore, it discharges the PCB board to be cut to a batch position and batch direction through position adjustment of a first position correction unit, a second position correction unit, and a pre-position fixing mechanism. Position fixing is implemented by directly using an inner layer target and direction indicator without requiring punching.

Description

Alignment Device for Inner-Layer PCB The present invention relates to the field of PCB board processing, and more specifically, to a position alignment device for an inner layer PCB board. After compression and lamination, the PCB boards must be trimmed at the edges. The CCD alignment machine, located on the related trimming and polishing production line (position aligner + trimming and polishing machine + chamfering machine + other equipment), typically uses through-holes to fix the position of the PCB board, while simultaneously inputting the relevant trimming data into the machine. The detailed steps are as follows. 1. Turn on the power switch of the equipment so that the equipment is placed in a material standby state; 2. Enter relevant information for the plate requiring cutting; 3. Place the plate at the material loading position of the cutting grinder; 4. The position aligner uses upward suction to transport the plate to the position fixing platform; 5. The CCD catches up the through-hole to fix the position, calculates the position where the two target holes deviate from the central axis, and again performs correction through upward suction and rotation and displacement of the moving cutting; 6. The position aligner transports the plate to the cutting grinder through upward suction to perform the cutting. While this processing method can achieve position fixation for PCB boards, it also has a defect in that position fixation and cutting cannot be performed on PCB boards where through-hole position fixation has not been achieved during the actual production process.
