Description

Technical Field

[0001] This utility model relates to the field of surface mount technology for circuit boards, and in particular to a feeding and placement device for a main control circuit board. Background Technology

[0002] The main control circuit board is a key component in the control system, comprising the circuit board and the electronic components soldered onto it. In automated surface mount technology (SMT) production lines, circuit boards are typically placed at intervals on a feed rack using a feeding device. In existing technology, the width of the feed rack is usually designed to be adjustable to accommodate circuit boards of different sizes, but its length adjustment presents the following problems:

[0003] Too short a length: When the circuit board is too long, the part that extends out of the feed rack is prone to tilting, resulting in unstable placement;

[0004] Excessive length: When the circuit board is too short, it is difficult for operators to insert it accurately, reducing efficiency.

[0005] Therefore, there is an urgent need for a device that can flexibly adjust the length of the feed rack and improve placement stability. Utility Model Content

The hinge shaft is rotatably connected to the outer top plate, and the inner end of the outer top plate abuts against the outer wall of the vertical plate to assist in the insertion and removal of the insertion rod.

[0018] Synchronization adjustment mechanism:

[0019] An oblique component is welded to the lower wall of the lower plate. An oblique hole is made in the oblique component, and a movable rod is inserted into the oblique hole.

[0020] The lower end of the movable rod is connected to the movable lower plate, and a concave part is vertically provided on the movable lower plate.
