Feeding frame of printed circuit board

Abstract

The invention discloses a feeding frame of a printed circuit board. The feeding frame comprises a main plate assembly and an auxiliary plate assembly which are arranged right opposite to each other, the feeding frame further comprises side frames symmetrically arranged on two sides of the length direction of the main plate assembly, each side frame comprises cross beams arranged parallel with themain plate assembly, and the cross beams are mounted on the main plate assembly through at least two vertically arranged upright posts; the auxiliary plate assembly is mounted on the cross beams of the two side frames; the opposite sides of the main plate assembly and the auxiliary plate assembly are provided with plate grooves which are opposite to each other, the plate grooves are arranged in the width direction of the main plate assembly and the auxiliary plate assembly in a penetrating mode, and the plate grooves are arranged in equal distance in the length direction; and each upright postcomprises a main upright post and an auxiliary upright post telescopically arranged on the main upright post, and locking mechanisms used for locking and fixing the auxiliary upright posts relative to the main upright posts are further mounted on the main upright posts. The feeding frame has the advantages of being ingenious in structural design, convenient to operate and use, good in universality, high in repeated utilization rate, and beneficial to reducing investment cost.

Description

technical field [0001] The invention relates to the technical field of integrated circuit board production and manufacturing, in particular to a material loading rack for printed circuit boards. Background technique [0002] The printed circuit board is mainly responsible for providing the wiring circuit for the electrical connection of electronic components. The manufacturing process of the printed circuit board includes multiple processes. Due to the large number of electronic components soldered on the printed circuit board and their different characteristics, the electronic components need to be soldered in batches , In order to ensure the consistency of welding quality, automatic welding equipment is usually used to complete the placement and welding of electronic components, and the printed circuit board is transported to the automatic welding equipment through a conveyor belt. At present, in order to automatically load the printed circuit boards onto the conveyor belt...

AI Technical Summary

Problems solved by technology

At present, in order to automatically load the printed circuit boards onto the conveyor belt, the printed circuit boards are first layered on the shelf slots of the loading rack. However, due to the different widths of different types of printed circuit boards, the same loading rack It cannot be applied to different types of printed circuit boards, which makes the universality of the loading rack poor, the utilization rate is low, and the input cost is high
