PCB (Printed Circuit Board) alignment device

Abstract

The invention relates to a PCB (Printed Circuit Board) alignment device, which comprises two transmission belts used for transmitting a PCB arranged thereon; a jig is arranged on the alignment assembly in a bearing manner; wherein the conveying belts are driven by an adjusting driver so as to adjust the distance between the two conveying belts, and the alignment assembly is located below the conveying belts; an alignment assembly comprises a jacking component for lifting the PCB and a horizontal adjusting component, and the jig is supported on the horizontal adjusting component; after the movable end of the jacking component jacks the PCB and separates the PCB from the conveying belts, the driver is adjusted to drive the two conveying belts so that the PCB can penetrate through the gap between the two conveying belts; after the jacking component jacks the PCB, the horizontal adjusting component drives the jig to be adjusted in the horizontal direction so that the jig can correspond to the PCB, and when the jacking component resets, the distance between the PCB and the jig is shortened, and finally the PCB is placed at the fixed position of the jig in a bearing mode.

Description

technical field [0001] The invention relates to the field of non-standard assembly, in particular to a PCB board alignment device. Background technique [0002] In the assembly process of the PCB board, especially in the reflow process of the PCB board, in order to ensure the strength of the solder joints on the PCB board, the PCB board needs to be placed in a reflow furnace to reflow the solder joints, and the PCB board Before the board is put into the reflow furnace, the PCB board needs to be loaded into the jig. In the actual assembly process, in order to limit the PCB board in the jig, there are often settings on the jig that can be connected to the components on the PCB to form a limit. The positioning block of the bit structure, specifically, often uses the PIN pin or the PIN hole on the PCB as the limiting part; however, the components on the PCB are often installed on the board by welding, which also easily leads to During the installation process, on the premise of...

[0002] During the PCB assembly process, especially in the PCB reflow process, in order to ensure the strength of the solder joints on the PCB, it is necessary to place the PCB on The solder joints are reflowed in the reflow furnace, and before the PCB board is put into the reflow furnace, the PCB board needs to be loaded into the jig, and in the actual assembly process, in order to limit the PCB board in the jig, Fixtures are often provided with positioning blocks that can be connected with components on the PCB to form a limiting structure. Specifically, PIN pins or PIN holes on the PCB are often used as limiting components; however, components on the PCB are often soldered. It is installed on the board in the same way, which also easily leads to deviations in the installation position of the components on each PCB board on the premise of ensuring the normal operation of the components during the installation process. At the same time, the position of the positioning block on the fixture It is fixed. Before loading the PCB board into the jig, adjust the position of the PCB board so that it corresponds to the jig. In this operation project, the mechanical arm is required to grab the PCB board and adjust the position of the PCB board, and finally load it into the However, at the same time, the volume of the robotic arm is relatively large, and the cost of the robotic arm is relatively high, which will easily lead to an increase in the volume of the device and an increase in manufacturing costs
