Abstract

The invention discloses a printing equipment pneumatic device. The printing equipment pneumatic device comprises scrapers, scraper connecting devices and scraper control devices used for controlling the scraper connecting devices to move up and down, wherein each scraper connecting device comprises a scraper supporting shaft, a scraper connecting plate, a gland and a connecting device fixing plate, the scrapers are fixedly connected with the scraper connecting plates, the connecting device fixing plates are fixedly connected with the scraper control devices, the glands are tightly attached tothe outer side surfaces of the scraper connecting plates, and a balance block used for balancing one scraper is fixed to the inner side surface of each scraper connecting plate; each scraper control device comprises a transmission device, an upper mounting plate, a lower mounting plate and an air cylinder; the transmission devices control the upper mounting plates to move up and down; and the aircylinders and the connecting device fixing plates are fixedly connected with the lower mounting plates. The scraper connecting plates are in bearing connection with the scraper supporting shafts, andwhen the scrapers make contact with a steel mesh, the scraper connecting plates can drive the scrapers to rotate along the scraper supporting shafts so as to adjust the angles of the scrapers, so thatthe scrapers make full contact with the steel mesh, and the convenience and the practicability are achieved.

Description

[0001] This application is a divisional application of the Chinese patent application with the application number 201610654069.5 and the title of the invention "A Pneumatic Device for Printing Equipment" submitted on August 10, 2016. technical field [0002] The invention relates to the technical field of PCB board printing solder paste, in particular to a pneumatic device for printing equipment. Background technique [0003] In the process of PCB (Printed Circuit Board, printed circuit board) production and processing, printing solder paste is an important process. When printing solder paste, it is necessary to ensure full contact between the scraper and the stencil, and the strength is moderate, otherwise, the produced PCB is unqualified. With the existing pneumatic device of printing equipment, when the placement angle of the squeegee is wrong or the squeegee is slightly tilted, some parts of the stencil cannot be in contact with the squeegee, and the PCB produced by it i...
