Embodiment Construction

[0029] In order to describe the technical content, structural features, achieved goals and effects of the present invention in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings.

[0030] see figure 1 , a visual alignment method for a solder paste printing machine in this embodiment, comprising steps:

[0031] S1. Set the standard position image data corresponding to the designated area on the PCB board to be printed. Any area can be designated as the designated area. Generally, a certain pad will be designated as the designated area;

[0032] S2, obtain the actual position image data of the specified area on the PCB board to be printed from the fixed position, because the image data of the specified area is obtained from the fixed position, so the acquisition equipment such as the CCD camera that collects the image data can be fixed, so can Quickly and accurately collect the image data of the actual position, and a...

Abstract

The invention discloses a vision aligning method of a solder paste printing press. The method comprises the following steps: S1, setting standard position image data corresponding to an appointed area on a PCB (Printed Circuit Board) to be printed; S2, acquiring practical position image data of the appointed area on the PCB to be printed from a fixed position; S3, comparing the acquired practical position image data with the standard position image data so as to acquire deviation data of the practical position and the standard position; and S4, adjusting the position of the PCB according to the deviation data so as to position the appointed area on the PCB in the standard position. The invention further discloses the solder paste printing press which comprises an image sensor which is fixedly arranged on a circumferential side between the PCB and a mold plate. According to the solder paste printing press and the vision aligning method, the image data of the appointed area can be acquired from the fixed position, the speed for acquiring the image data is improved, mechanical structures for supporting acquisition equipment such as a CCD (Charge Coupled Device) image sensor to move along an X-axis and a Y-axis are reduced, the structure is simple, and the cost is lowered.

Description

technical field [0001] The invention relates to the field of solder paste printing of PCB boards, in particular to a solder paste printing machine and a visual alignment method thereof. Background technique [0002] Existing solder paste printing machines generally include visual image system, platform correction system, PCB transport and clamping system, scraper system, screen frame system and cleaning system. in, [0003] The PCB transportation and clamping system is used to transport the PCB board to the set position and clamp and fix it, and then carry out the image acquisition and alignment of the vision system. [0004] The screen frame system includes a template and a clamping device. The template is provided with a hole corresponding to the solder paste printing position of the PCB board, which is used to align the fixed PCB board pad for solder paste printing. The template is usually made of steel mesh or silk screen. made. [0005] The visual image system is use...
