Description

Technical Field

[0001] The invention belongs to the technical field of automated production, and relates to an automatic material matching system for precision optomechanical and electrical products used in assembly production. Background Art

[0002] With the annual increase in the output of precision optomechanical products, ensuring product quality and improving production efficiency have become the top priorities in the production of precision optomechanical products. For precision optomechanical products, their performance level depends on the performance of optomechanical components. In scientific research and production, it is found that optimizing matching and matching according to specific rules for specific performance indicators of optomechanical components can greatly improve the performance of precision optomechanical products. Therefore, after the dispatcher receives the optomechanical components from the warehouse, he needs to extract the specific performance indicators and number information from the corresponding reports and certificates into an EXECL, and sort them in ascending or descending order. After sorting, according to the different matching rules of each model of precision optomechanical products, the optomechanical components are allocated to each precision optomechanical product, and finally the final precision optomechanical product matching table is sorted out, and it is provided to the assembler together with the optomechanical components. During the assembly process of precision optomechanical products, the assembler finds the required physical objects from many optomechanical components according to the matching table and assembles them.

[0003] Usually, precision optomechanical products involve 6 to 25 types of optomechanical components, and there are differences between each type of precision optomechanical products. The above operations are completely completed manually, which may be time-consuming, inaccurate matching, wrong picking, or missing picking, affecting production progress.

[0004] In the prior art, "Distribution method, distribution vehicle, computer-readable storage medium and electronic device" (application number: 202010197095.6) proposes to select the load-bearing station that is used preferentially on the main body, bind the order to the corresponding encoding part, and realize the distribution of goods, thereby reducing physical exertion during the distribution process.

[0005] In the "Logistics distribution method and device, storage medium and electronic equipment" (application number: 202210021738.0), multiple outbound orders are combined into waves, and picking tasks are generated according to the waves, which realizes the merging of multiple waves and improves the distribution efficiency.

[0006] In the "Item Sorting Method and Device" (application number: 202111629219.4), the item sorting type is first determined, and different types of sorting tasks are generated according to the sorting type, and bound to different types of grids, thereby improving the picking efficiency of the grid station sorting operation.

[0007] In summary, existing research on distribution systems, equipment and methods is currently mainly aimed at automatic scheduling and optimization control inside distribution cabinets, and does not involve specific application method innovations in production scenarios, especially assembly production preparation scenarios, and the system innovations proposed thereby.

[0008] Therefore, the use of automated means to automatically match the optomechanical components of precision optomechanical products is of great significance for improving the production efficiency and quality of the assembly process. Summary of the invention

[0009] The technical problem solved by the present invention is: to overcome the shortcomings of the prior art and propose an automatic material matching system for precision optomechanical and electrical products for assembly production, to automatically match the optomechanical and electrical components of precision optomechanical and electrical products, and to achieve automatic matching and comprehensive management and control of the physical flow and information flow of materials to be assembled.

[0015] Furthermore, the intelligent material information collection module includes a paper certificate scanning and input submodule and an information identification submodule;

[0016] The paper certificate scanning and input submodule is composed of a scanner with self-feeding function and the ability to output double-layer PDF files and a host machine, which can realize the automatic scanning of paper certificates of batch materials and the function of uploading electronic files;

[0017] The information identification submodule extracts the material number, material specification, material batch, and material key indicator information in the key fields from the electronic files uploaded to the host computer, and uses a combination of barcode recognition extraction and OCR text recognition extraction to output and save the identified and extracted material information in a predetermined format and send it to the automated material assembly module.

[0018] Furthermore, the automated material assembly module includes a data input and output module, a database, and a data processing module;

[0021] The data processing module optimizes and matches the material indicators contained in the database according to the set material matching algorithm, generates a material matching table, and sends it to the material physical distribution hardware subsystem through the database and data input and output modules.

[0022] Furthermore, the set material assembly algorithm is specifically as follows:

[0024] For each component required for the precision optomechanical products that do not require component index matching at all, sort them in order of material code from small to large, select a group of components with the smallest material code as the components of the first set of optomechanical products; select a group of components with the second smallest material code as the components of the second set of optomechanical products; ...; select a group of components with the largest material code as the components of the Mth set of optomechanical products; finally complete the material matching of all the required M sets of precision optomechanical products, and obtain a material matching table;

[0025] 2) For precision optomechanical products that require all or part of the components to match the indicators, the material assembly algorithm for optomechanical components is:

[0026] For components with index matching requirements, logarithmic operations are performed on the indicators required to be assessed for each type of component and multiplied by the characteristic coefficient to obtain the conversion index values ​​of each type of component; the conversion index values ​​of each type of component are sorted in ascending order, and the empirical assembly rules of optomechanical products are referred to, including the conversion index values ​​of n types of components are taken from the largest to the smallest, and the partial material matching relationship of M sets of products is obtained; the conversion index values ​​of n-1 types of components are taken from the largest to the smallest, and the conversion index values ​​of another type of components are taken from the smallest to the largest, and the partial material matching relationship of M sets of products is obtained; ...; the conversion index values ​​of one type of component are taken from the largest to the smallest, and the conversion index values ​​of n-1 types of components are taken from the smallest to the largest, and the partial material matching relationship of M sets of products is obtained;

[0027] For components that do not require indicator matching, the material matching relationship of the remaining components of M sets of products is obtained according to the material matching algorithm of precision optomechanical products that do not require indicator matching of components, and the material matching table of multi-axis integrated precision optomechanical products is summarized; n and M are both positive integers greater than 1.

[0028] Furthermore, the material matching table generated by the data processing module is uploaded to the MOM or MES production execution management system through the software interface.

[0029] Furthermore, the material physical distribution hardware subsystem includes an automated material distribution mechanism and an adaptive buffer feeding mechanism;

[0030] The automated material distribution mechanism has the function of accurately transferring the components and subassemblies of each set of precision optomechanical products to the corresponding material boxes according to the material matching table, wherein each material box corresponds to the components and subassemblies of a set of precision optomechanical products; after receiving the matching control signal of the automated material distribution mechanism, it automatically sends an I / O request signal to the adaptive buffer loading mechanism, and the adaptive buffer loading mechanism returns an I / O response signal when the conditions are met, thereby starting the material transfer and distribution operations.

[0031] Furthermore, the adaptive buffer feeding mechanism comprises:

[0032] The frame is used to fix the various components of the adaptive buffer feeding mechanism and to connect with the conveyor belt of the automatic material distribution mechanism;

[0033] The material storage drawer, which serves as the initial storage area for materials loaded in manual batches, is fixed on the rack;

[0034] The material lifting mechanism, as a mechanism for automatically adjusting the height of the material, is fixed on the frame and has a tray that can move up and down;

[0035] The handling module assembly is a motion actuator that moves the material from the material lifting mechanism to the conveyor belt of the automatic material spreading mechanism after the material is grabbed, and is fixed on the frame;

[0036] The material grabbing component, as the end effector for automatically grabbing and placing materials, is fixed on the moving part of the handling module component, and includes electric or pneumatic grippers and electric or pneumatic suction cups.

[0037] Furthermore, the material storage drawer has a hollow structure at the bottom, the non-hollow part of the bottom edge is used to support the materials loaded in batches manually, and the hollow part is used for the up and down movement of the material lifting mechanism and the materials it supports.

[0038] Furthermore, the tray size of the material lifting mechanism is smaller than the bottom hollow structure of the material storage drawer, and can extend upward from the hollow structure to lift the materials loaded in manual batches and move them upward.

[0039] The beneficial effects of the present invention compared with the prior art are:

[0040] (1) The automatic matching system for precision optomechanical products proposed in the present invention solves the problem that the manual search, input, and calculation of data are time-consuming and error-prone due to the fact that the matching data is not bound to the physical object during the assembly preparation process of precision optomechanical products, and the manual search and placement of physical objects for single product number management is time-consuming and error-prone;

[0041] (2) The present invention solves the problem that the data of the component certificates of precision optomechanical products have long been stored in paper documents and data utilization requires manual search and entry through the combined application of self-feeding paper scanning and output of double-layer PDF files, specific field OCR recognition and data barcode recognition, thereby realizing the paperless certification of the component certificates of precision optomechanical products;
