Excellent automatic PCB placing method

Abstract

The invention discloses an excellent automatic PCB placing method. The excellent automatic PCB placing method comprises the following steps: a, setting inductors P and Q; b, reading the PCB information; c, automatically placing the plate; and d, automatically adjusting the position. According to the invention, PCBs of any size can be produced according to a front-back fixed interval when moving on a horizontal conveying line, the board placing efficiency is improved, a segmented offset placing mode is adopted for small-size PCBs, manual intervention is not needed, the accuracy is high, frequent use of part of grinding wheels in a back-section grinding process is prevented, the loss uniformity of equipment is improved, and the production cost is reduced. The device is uniform in abrasion of rear-end equipment, stable in grinding uniformity of the equipment, high in production efficiency, long in service life of the brush roll and capable of saving cost, does not need to frequently stop a line to brush the brush roll, can realize accurate fixed-point blanking, can reduce the running track of a blanking manipulator, is convenient for the manipulator to accurately and quickly grab and blank, improves the productivity, and is suitable for large-scale popularization and application. And the requirements of the actual production process are better met.

Description

technical field [0001] The invention relates to the technical field of PCB production, in particular to an excellent PCB automatic board placement method. Background technique [0002] PCB is more and more widely used and has many unique advantages, such as high density, high reliability, designability, producibility, testability, assembly and maintainability, etc., as the most widely used electronic components product. [0003] Disadvantages of the existing technology: [0004] At present, in the field of PCB manufacturing, there are mainly two types: manual manual board placement and robotic automatic board placement. Manual manual board placement is greatly affected by personnel subjectivity and wastes manpower. The PCB board is easy to tilt, and the board spacing is uneven. : Compare the length A of the PCB size with the width L of the horizontal line. If A≤L, the PCB board is placed horizontally into the track; if A>L, the PCB board is placed vertically into the tr...

Problems solved by technology

The logic of placing boards left and right is that the first board is placed on the far left of the track, the second board is placed on the far right of the track, and so on. The odd number of boards is placed on the far left, and the even number of boards is placed on the far right. The automatic placement of the manipulator cannot Realize the fixed distance between the front and back of the board of all sizes, resulting in waste of production capacity; when the width of the PCB size is smaller than the width of the horizontal line body, since the position of the needle of the manipulator is fixed, after the process of pressing and trimming the board, the two sides of the board The thickness will be thicker than that of the middle part of the plate, the friction between the thicker area and the grinding wheel is greater, and the degree of wear is relatively deep, resulting in the part of the rear grinding wheel not touching the plate surface, so the loss of the grinding equipment itself is Uneven, resulting in poorer and worse grinding uniformity of the equipment. Although the grinding wheel will be ground through the corresponding device to ensure the uniformity of the surface of the grinding wheel, it will further accelerate the wear of the grinding wheel;

[0005] At the same time, due to the use of different positions for placing the boards, although there are certain rules, the adjacent boards are located on both sides of the conveying track, resulting in the need to set two different feeding points during the feeding process, and set the corresponding manipulator to run regularity, which reduces work efficiency to a certain extent
