Mobile phone key spraying device

Abstract

The invention discloses a mobile phone key spraying device. The mobile phone key spraying device comprises an ink supply pump, ink dollies, more than two spray guns and connection pipelines, wherein the ink dollies comprise an ink dolly A and an ink dolly B; the more than two spray guns are divided into a spray gun group A and a spray gun group B; the connection pipelines comprise a connection pipeline A and a connection pipeline B; the ink dolly A and the spray gun group A are connected to the ink supply pump by the connection pipeline A; and the ink dolly B and the spray gun group B are connected to the ink supply pump by the connection pipeline B. The mobile phone key spraying device can be obtained by simple reconstruction of the existing spraying device, can effectively reduce material waste and time waste in pipeline changing and can improve an equipment utilization rate.

Description

technical field [0001] The invention relates to production equipment for mobile phone keys, in particular to a spraying device for mobile phone keys. Background technique [0002] The mobile phone button is a part on the mobile phone for function control operation, such as figure 1 The mobile phone button structure shown is a common one in the prior art, and the whole process from production to shipment is as follows: [0003] 1. Forming: use rubber material to form multiple frame-shaped plastic substrates connected together; [0004] 2. Printing: printing ink on the surface of the plastic substrate to form a primer layer 2; [0005] 3. Spraying the bottom: spray ink on the primer layer 2 to form the appearance ink layer 3; [0006] 4. Spraying surface: spray ink on the appearance ink layer 3 to form a protective ink layer 4; [0007] 5. Die-cutting: Die-cut a plurality of connected frame-shaped plastic base materials into a single button base material (1) through stampi...

AI Technical Summary

Problems solved by technology

Existing spraying equipment such as figure 2 As shown, usually each ink supply pump corresponds to a pipeline with four spray guns, and the ink in the ink trolley is delivered to the pipeline through the ink supply pump, and sprayed on the plastic substrate by the spray gun to supply a kind of ink; In order to avoid pollution during line change, the entire line and spray gun must be thoroughly cleaned, and the residual ink in the pipeline and spray gun is discarded, which wastes a lot of materials and time; moreover, every change must be cleaned
