Description

Improve three proofings lacquer and pollute dress mechanism Technical Field The utility model relates to the technical field of main board processing, in particular to a mechanism for improving pollution of three-proofing paint. Background In the field of electronic manufacturing, spraying paint is a critical surface treatment process in the production process of a motherboard (such as a computer motherboard) to provide a protective layer and an aesthetic effect. In the conventional spraying operation, since varnish is easily left on the work table, a jig plate is often used to fix the main plate and shield the non-spraying area of the work table, to prevent contamination and to ensure the accuracy of spraying. However, the design of the existing fixture plate has a certain limitation that the mechanism for fixing the main plate often interferes with the movement path of the paint head, so that the paint head cannot completely cover certain areas of the main plate, and the uniformity and the integrity of spraying are affected. This problem is particularly acute in the manufacture of precision electronic components, as any localized spray defects can adversely affect the performance or appearance of the product. Disclosure of utility model This section is intended to outline some aspects of embodiments of the utility model and to briefly introduce some preferred embodiments.
