Abstract

The invention relates to etching equipment, in particular to printed circuit board (PCB) etching equipment for production of an electronic display screen. The PCB etching equipment, which can be usedfor reducing labor intensity of a worker, is high in etching efficiency and is convenient to operate, for the production of the electronic display screen is provided by the invention. In order to solve the technical problem, the PCB etching equipment for the production of the electronic display screen comprises a left rack, a first pipeline, a first one-way valve, a support rod, a bottom plate, amobile device, a lifting device, a rotation device, a liquid transmission device and a second one-way valve, wherein the left rack is welded at a left side of the top of the bottom plate, and the liquid transmission device is arranged at a lower part of a right side of the left rack. By the PCB etching equipment, the rotation direction of an electric winding wheel is controlled, the effects of rapidly collecting and placing a PCB is achieved by matching of the electric winding wheel and a first spring, a rotation motor is controlled to rotate, a cam and a second spring are matched with each other, an etching liquid is stirred by rotating rotation blades, so that the PCB and the etching liquid are in full contact, and the etching efficiency is improved.

Description

technical field [0001] The invention relates to an etching device, in particular to a PCB etching device for electronic display screen production. Background technique [0002] The display screen is composed of several display units (unit display panels or unit display cabinets) that can be combined and spliced, plus a set of appropriate controllers (main control board or control system). Therefore, display panels (or unit boxes) of various specifications can be combined with controllers of different control technologies to form many kinds of LED displays to meet the needs of different environments and different display requirements. [0003] PCB, the Chinese name is printed circuit board, also known as printed circuit board, is an important electronic component, a support for electronic components, and a carrier for electrical connections of electronic components. Because it is made using electronic printing, it is called a "printed" circuit board. [0004] Etching is the...
