Problems solved by technology

[0003] 1. Manually inserting the Flex soft board into the BMU board not only has the risk of the socket of the BMU board being squeezed and damaged, but also easily leads to the scrapping of the BMU board, and is inefficient. In order to meet the needs of the production line, labor costs need to be increased; 2. Manual installation Inserting, it is impossible to insert to the same depth, and the error is large, which affects the subsequent station test results and reduces the pass rate of the BMU board; 3. Since the BMU board is small, it needs to be picked up with tweezers, and the surface of the BMU board is easy to leave Indentation and bruising affect the quality

Embodiment Construction

[0048] The general idea of ​​the technical solutions in the embodiments of the present application is as follows: the risk of damage to the BMU board is reduced by the automatic insertion of the manipulator, and the insertion time is shortened; through the set first offset threshold, second offset threshold, third offset threshold Offset threshold and width range Check the offset and total offset of the BMU board and the Flex board, and check the actual width after the BMU board and the Flex board are plugged together to avoid excessive offset. As a result, the plugging fails, and the situation that the plugging is not in place or the plugging is too far is found in time, so as to improve the accuracy, efficiency and quality of the plugging of the BMU board and the Flex soft board.

[0049] Please refer to Figure 1 to Figure 3 As shown, a preferred embodiment of a visual guidance-based automatic plugging method of the present invention includes the following steps:

Abstract

The invention provides an automatic insertion method and system based on visual guidance, and belongs to the technical field of BMU board testing. The method comprises the steps that S10, an offset threshold value and a width range are set; step S20, performing visual calibration on the BMU board and the Flex soft board to obtain reference coordinates; s30, placing the BMU board and the Flex soft board on a jig and rotating the BMU board and the Flex soft board to a preset angle; s40, the PLC obtains the BMU coordinates of the BMU board through the upper camera, and after the Flex soft board is sucked to the photographing position of the lower camera through the mechanical arm, the Flex coordinates of the Flex soft board are obtained through the lower camera; s50, after the PLC verifies the BMU coordinates and the Flex coordinates through the offset threshold value and the reference coordinates, the manipulator is controlled to automatically insert the Flex soft board into the BMU board; and step S60, the actual width after insertion is obtained through the upper camera, and the actual width is verified by using the width range. The method has the advantages that the precision, the efficiency and the quality of opposite insertion of the BMU board and the Flex soft board are greatly improved.

Description

technical field [0001] The invention relates to the technical field of BMU board testing, in particular to an automatic plugging method and system based on visual guidance. Background technique [0002] In the 3C field, the BMU board is a PCBA board used to protect the battery, and the BMU board needs to be tested after production. To test the BMU board, the Flex soft board needs to be inserted into the BMU board. The traditional method of manual insertion has the following disadvantages: [0003] 1. Manually inserting the Flex board to the BMU board not only has the risk of the socket of the BMU board being squeezed and damaged, but also easily leads to the scrapping of the BMU board, and the efficiency is low. In order to meet the needs of the production line, labor costs need to be increased; 2. It cannot be inserted to the same depth, and the error is large, which affects the test results of subsequent stations and reduces the pass rate of the BMU board; 3. Since the BM...
