Abstract
Description
Technical Field
[0001] The invention relates to the technical field of material feeding, and in particular to a group material feeding method for a surface mounting process. Background Art
[0002] Surface-Mount Technology (SMT) is an electronic assembly technology that directly mounts electronic components on the surface of a printed circuit board (PCB). It is a key technology in the modern electronic manufacturing industry. Compared with traditional through-hole insertion technology, it can achieve miniaturization, high performance and high reliability of electronic products. Its process flow includes: printing, placement, soldering, inspection and rework.
[0003] At present, the conventional production flow of PCB boards in the SMT process is: after the production of one model of products is completed, and then the products of another model are produced, the warehouse will first prepare all the materials of one model, and then prepare the materials of another model. The warehouse will separate the products of different models for wear and loss, and the production line will separate the products of different models for "Changeover action", that is, the production process of switching from one product to another, which includes operations such as adjusting the machinery and equipment, changing the mold, resetting the parameters; then the products of different models are produced separately. Summary of the invention
[0004] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a group feeding method for surface mounting process. Products of different models are grouped together to prepare materials, and then they are produced separately. The common materials between different models can be prepared in one time in the warehouse and sent to the production line for use, thereby reducing the number of times the common materials are repeatedly prepared and the wear and tear caused by repeated distribution, while reducing the conversion time and improving the production efficiency of the production line.
[0005] In order to achieve the above object, the technical solution adopted by the present invention is: A grouped material feeding method for a surface mount process first obtains materials required for the production of different products through a material preparation table; then the same common materials are screened out, and a general material preparation table after the materials are grouped and merged is prepared; and then, according to the general material preparation table, the common materials of different products are placed on the same machine and the same station for production, and different materials are placed on their respective corresponding machines and stations for production.
[0006] Optionally, when preparing materials in the warehouse, the common materials of different products are grouped and combined into the same tray according to the overall material preparation list, and then sent to the production line for use.
[0007] Optionally, materials are delivered between the warehouse and the production line by manual labor, automated guided vehicles or conveyor belts.
[0008] Optionally, for the common materials of multiple machine models, the warehouse staff can prepare them all at once, and the production line staff can combine the common materials and install them on the machines for use at one time.
[0009] Optionally, there are two types of products, A and B, which are produced by machine type A and machine type B respectively; the common materials of product A and product B are placed on the same machine and station for production.
[0010] Optionally, when preparing materials in the warehouse, the common materials of product A and product B are grouped together and combined into the same tray of materials and sent to the production line for use.
[0011] Beneficial Effects
[0012] In the present invention, products of different machine types are grouped together and combined to prepare materials through group feeding, and then produced separately; so that the common materials between different machine types can be prepared at one time in the warehouse and sent to the production line for use, thereby reducing the number of times the common materials are repeatedly prepared and the wear and loss caused by repeated distribution, while reducing the conversion time and improving the production efficiency of the production line. BRIEF DESCRIPTION OF THE DRAWINGS
[0013] Figure 1 It is a schematic flow chart of a group feeding method for a surface mounting process according to an embodiment of the present invention. DETAILED DESCRIPTION
[0014] The present invention will now be further described in detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.
[0015] like Figure 1 As shown, a grouped material feeding method for surface mounting process is firstly used to obtain materials required for the production of different products through the material preparation table; then the same common materials are screened out, and a general material preparation table after the materials are grouped and merged is prepared; and then, according to the general material preparation table, the common materials of different products are placed in the same machine and the same station for production, and different materials are placed in their respective corresponding machines and stations for production.
[0016] Through the group feeding method, products produced by different models are grouped together to prepare materials, and then produced separately; the common materials between different models can be prepared in one go in the warehouse and sent to the production line for use, thereby reducing the number of repeated preparations of common materials and the wear and tear caused by repeated distribution, while reducing conversion time and improving the production efficiency of the production line.
[0017] For the common materials of multiple machine models, the warehouse staff prepares them all at once, and the production line staff combines the common materials and prepares them and installs them on the machine for use at one time, changing the traditional process of preparing materials for each product separately and producing them separately. The products of multiple different machine models are grouped in the preparation of materials, replacing the original production process of repeated preparation of common materials for multiple machine models, repeated release of wear and tear, and repeated loading and unloading of materials.
[0018] This method can reduce the number of times common materials are repeatedly prepared and the wear and tear caused by repeated distribution, and reduce the repeated loading and unloading processes of common materials, thereby reducing changeover time and improving production line production efficiency.
[0019] In addition, materials are distributed between warehouses and production lines by manual labor, automated guided vehicles or conveyor belts. The production lines here are existing technologies, that is, where materials are processed.
[0020] Manual delivery is suitable for materials with small volume, light weight, short delivery distance and low delivery frequency, and is suitable for material delivery during slow production cycles. When material delivery requires high accuracy and efficiency, and the environment permits, AGV (automatic guided vehicle) is a good choice. AGV can automatically drive along a preset route to transport materials from the warehouse to the designated location of the production line. For production lines with continuous production and relatively stable material supply, conveyor belts are a commonly used delivery method, which can also be used to complete the delivery of materials between warehouses and production lines.
[0021] In the prior art, each machine model prepares materials separately, and the common materials between different machine models will be prepared multiple times on the same day, and the wear and tear of the common materials of different machine models will be issued multiple times; that is, the products of different machine models are programmed separately, and the common materials with the same material number in the products of different machine models are placed on different machines and different stations for production, as shown in Table 1-1 and Table 1-2.
[0022] Table 1-1 Model A: 70CVB00411E-SMT Loading list (Parts preparation list)
[0023] Table 1-2 Model B: 70CVB00412-SMT Loading list (material preparation list)
[0024] According to Table 1-1 and Table 1-2, there are two types of products, A and B, which are produced by machine A and machine B respectively; and in the prior art, the materials of product A and product B are prepared using two preparation tables, 45% of the materials of the two models are common materials, and the common materials of product A and product B are placed on different machines and stations for production; and when preparing materials in the warehouse, they are divided into 2 trays and then sent to the production line for use.
[0025] After adopting the method proposed in the present invention, multiple products are grouped into production programs, materials are prepared in groups, and common materials with the same material number in different products are placed on the same machine and the same station for production, that is, the common materials of product A and product B are placed on the same machine and station for production, as shown in Table 2-1.
[0026] Table 2-1 Grouped feeding: 70CVB00411E-SMT+70CVB00412-SMT Loading list (Material preparation list)
[0027] It can be seen from Table 2-1 that all materials for product A and product B are prepared using one material preparation master list; the common materials for product A and product B are placed on the same machine and production station for production, and when the warehouse prepares materials, the common materials of different products are grouped and combined into the same tray of materials according to the material preparation master list, and then sent to the production line for use; that is, when the warehouse prepares materials, the common materials for product A and product B are grouped and combined into the same tray of materials and sent to the production line for use.
[0028] The following is a comparative explanation of the methods before and after improvement in terms of material preparation quantity, wear and tear, and conversion time in combination with actual applications, as shown in Table 2-2, Table 2-3, and Table 2-4.
[0029] Table 2-2 Comparison of material quantities
[0030] Table 2-3 Wear and tear comparison table
[0031] Table 2-4 Conversion time comparison table
[0032] Before grouping: Stock quantity: 62 rolls (product A) + 61 rolls (product B) = 123 rolls; Loss quantity: 1560 pieces (product A) + 1520 pieces (product B) = 3080 pieces; Total time: 18 minutes (product A) + 18 minutes (product B) = 36 minutes.
[0033] After grouping: Stock quantity: 62 rolls (product A) + 5 rolls (product B) = 67 rolls; Loss quantity: 1560 pieces (product A) + 100 pieces (product B) = 1660 pieces; Total time: 18 minutes (product A) + 10 minutes (product B) = 28 minutes.
[0034] From this we can see that: The number of stock materials saved by grouping is 123-67=56 rolls, and the stock quantity saved is 45.6%. By reducing the stock quantity, cost reduction and efficiency improvement are achieved; The number of lost pieces saved by grouping is 3080-1660=1420, which is 46.1%; by reducing the loss, the cost increase is avoided and the profit is increased; The time saved by grouping is 36-28=8 minutes, and the total time saved is 22.2%. By reducing the changeover time, the loading and unloading actions during the changeover can be reduced, thereby improving production efficiency.
[0035] In summary, the group feeding method proposed in the present invention can realize fast, efficient and high-quality production of products in the surface mounting process, reduce the number of times of preparing common materials for different products, reduce the loss of common materials, reduce the production line conversion time, and improve the production line production efficiency.
[0036] Based on this, the problems of repeated preparation of common materials between different models on the same day, repeated installation and supply of common materials, and repeated distribution and loss of common materials can be solved. The loading and unloading actions during conversion can be reduced, the conversion actions can be completed quickly, the production line efficiency can be improved, and the products can be ensured to be produced on time, on demand, with guaranteed quality and quantity, thereby improving customer satisfaction.
