Automated 5G (the 5th generation wireless systems) base station ceramic filter production line

Abstract

The invention discloses an automated 5G (the 5th generation wireless systems) base station ceramic filter production line, and relates to the technical field of 5G communication. The production line comprises a drilling station, a grinding station, an ultrasonic wave cleaning station, a sliver paste spraying station, a single chip detection station, a stacking station, a sintering and forming station and an unloading package in sequence, wherein the sliver paste spraying station comprises a plurality of single-surface spraying groups, and each single-surface spraying group comprises spraying equipment, a second dryer and an overturning machine, and the spraying equipment, the second dryer and the overturning machine are connected in sequence. By use of the production line, spraying equipment is used for firstly obtaining the three-dimensional model of each end surface of monolithic ceramic, sliver paste spraying can be carried out on a corresponding end surface according to the parameters of the three-dimensional model, a hole structure arranged on the end surface can be favorably avoided, a concave-convex structure on the end surface can be favorably processed, and the sliver paste guarantees to be evenly sprayed and even in thickness. In addition, the whole production line is provided with various detection machines to carry out checkout and quality control on products. The whole product line realizes full automation production, and labor cost is greatly lowered.

Description

technical field [0001] The invention relates to the technical field of 5G communication, and more specifically refers to an automatic 5G base station ceramic filter production line. Background technique [0002] In the 3G / 4G period, the base station consists of three parts: the baseband processing unit BBU, the radio frequency processing unit RRU, and the antenna feeder system. In the 5G era, the three major components of the base station have undergone significant changes: (1) the BBU is split into a CU-DU two-level architecture; (2) the RRU is combined with a large-scale array antenna to form an active antenna AAU; (3) the original BBU part physical Layer functions are placed in the AAU. Among them, the filter, which is one of the key radio frequency devices, is particularly important in the technological upgrade of the 5G era. [0003] In the 3G / 4G era, the metal coaxial cavity filter is the mainstream choice in the market: the base station filter is a key component of ...

Problems solved by technology

In order to improve the performance of the ceramic filter, the silver paste layer is printed on the surface of the ceramic filter. The processing of the printed silver paste layer at home and abroad is relatively complicated and traditional. It is necessary to design a matching printing plate for ceramic filters of different specifications, resulting in Each product upgrade requires a corresponding upgrade of the production line (that is, to prepare a new batch of printing p
