Labeling mechanical hand based on PCB robot production line

Abstract

The invention discloses a labeling mechanical hand based on a PCB robot production line. The labeling mechanical hand comprises a base, a first drive device, a second drive device and a third drive device mounted on the second drive device. According to the labeling mechanical hand provided by the invention, the first drive device drives a first lead screw to rotate through a first motor, so that the second drive device is driven to move back and forth; the second drive device drives the third drive device to rotate by 360 degrees, so that labeling process requirements of different angles are met; an air cylinder solid valve group drives a pressure head air cylinder group to act, so that a guide rod moves downwards; when a sucking disc stops moving downwards after being in contact with a PCB, a connecting plate continuously pushes a buffer spring to compress downwards as a result of working stroke of the pressure head air cylinder group, so that a label is compacted and is firmly adhered on the PCB, and therefore, the label is prevented from being in hard contact with the PCB to damage precise circuit boards or components and parts, and the good protection effect is achieved. The labeling mechanical hand further has the advantages of being simple in structure, low in manufacturing cost, and stable in reliable in operation.

Description

technical field [0001] The invention relates to the field of automation equipment, in particular to a labeling manipulator based on a PCB board (circuit board) robot production line. Background technique [0002] In recent years, with the continuous development of the domestic economy, labor costs have risen accordingly, and my country's manufacturing manpower advantage is no longer there. Under the background of manufacturing upgrading, "machine substitution" to improve the intelligence of manufacturing industry has become a new trend. At present, the automation rate of my country's 3C industry is still low, and there is still a huge demand for automation transformation. 3C products consist of a large number of components (for example, a mobile phone includes touch screen, display panel, main board PCB, battery, middle board, back cover and other large components, as well as other small components such as camera and structural components), and they are basically non-standar...

Problems solved by technology

However, the related parts manufacturing technology and complete machine assembly technology (such as mobile phone shell, glass, cover plate, etc.) have quite mature technology and equipment, high repetition of processing content, high labor intensity, and conform to the characteristics of automation transformation. 3C industry Automation upgrading and transformation will be the blue ocean of intelligent transformation

[0003] Disadvantages of the existing production line: 1) If the positioning of the sheet is not accurate, the product defect rate is high; 2) The production line produces a single product, and the change of the production line tooling and fixture changes greatly and the cycle is long; 3) It is impossible to break through a single station to complete different types of labels Automatic labeling

However, because the existing PCB production line process is completed by a single-suction head labeling machine, there are deficiencies in terms of labeling speed, labeling flexibility, and labeling reliability, and it also increases the cost of the PCB production line.
