Description

Technical Field

[0001] This invention belongs to the field of electromechanical equipment assembly technology, and particularly relates to a method for fitting and assembling printed circuit boards in narrow spaces. Background Technology

[0002] As industrialization deepens, enterprises need to continuously produce diverse products to meet the needs of different market players in order to survive in the market. The diversified demands of market players have greatly enriched the range of products produced. Modern industrial products often integrate mechanical structures, electrical control systems, and application software. The product lifecycle typically includes project initiation, requirements analysis, feasibility analysis, design and development, manufacturing, assembly, debugging, packaging, and sales. To improve operational efficiency, the lifecycles of the mechanical structure, electrical control, and application software components of an electromechanical product often proceed simultaneously. However, the design, development, and manufacturing times for these components differ significantly. The design, development, and manufacturing process for the electrical control system generally includes integrated circuit layout design, integrated circuit board fabrication, electronic component mounting, and electronic component soldering, while the mechanical structure... The design, development, and manufacturing process of the mechanical structure includes: designing the overall mechanism, drawing engineering drawings of each component, material cutting, machining, welding, heat treatment, surface treatment, and partial assembly. It is evident that compared to the electrical control system, the mechanical structure involves more steps and takes longer to design, develop, and manufacture. If a manufacturing error or processing error occurs in any step of the mechanical structure process, it often results in insufficient assembly space for the electrical control system during the final assembly process, or even makes assembly impossible. In such cases, completely overhauling the mechanical structure would inevitably require even longer rectification time, which is counterproductive. Therefore, during the final assembly process of electromechanical products, to compensate for errors in the mechanical structure during the early processing stages, the electrical control system should be rectified as much as possible. The design of the electrical control system should be adjusted to ensure compatibility with the mechanical structure, thereby maximizing the company's operational efficiency. Summary of the Invention

[0003] To address the aforementioned technical problems, this invention provides a method for fitting and assembling printed circuit boards in narrow spaces.

[0004] This invention provides a method for fitting and assembling printed circuit boards in narrow spaces, comprising the following steps: Step 1: Provide the circuit board; Step 2: Process the circuit board described in Step 1 to obtain a printed circuit board. The printed circuit board consists of multiple rigid plates and multiple flexible plates, and the flexible plates are connected between two adjacent rigid plates. Step 3: Fold, bend, or twist the flexible plate of the printed circuit board described in Step 2 to produce a multi-fold circuit board, and make the length direction of the multi-fold circuit board coincide with the preset feature trajectory line; Step 4: Use fasteners to install the multi-fold circuit board described in Step 3 into the narrow space.

[0005] In step one, multiple rigid regions, multiple flexible regions, and multiple cutting regions are drawn on the surface of the circuit board. The multiple rigid regions and multiple flexible regions are distributed along preset feature leads, and any flexible region is connected between two adjacent rigid regions, and any rigid region is connected between two adjacent flexible regions.

[0006] The feature lead is a multi-fold line that bends and meanders multiple times along the width direction of the circuit board.

[0007] The rigid region, flexible region, and cutting region are all rectangular in shape, and the length direction of the rigid region coincides with the width direction of the circuit board, and the length direction of the flexible region coincides with the length direction of the circuit board.

[0008] The circuit board described in step one is rectangular in shape.

[0009] In step one, the distribution design of wires and electronic components is also carried out within the rigid region.

[0010] Step one is performed on a computer using the Altium Designer software.

[0011] The characteristic trajectory line mentioned in step four is a straight line segment, a multi-curved line segment, or a multi-fold straight line segment.

[0012] The fasteners mentioned in step four include bolts, nuts, flat washers, and elastic washers.

[0013] The beneficial effects of this invention are as follows: By using the technical solution provided by this invention, a flexible plate is set on the circuit board, so that the surface of the circuit board can be folded along the flexible plate while ensuring that it can support enough electronic components and wires, thus making a three-dimensional multi-fold circuit board. The multi-fold circuit board can be more easily installed in the narrow space of electromechanical products, improving the assembly fit between the circuit board structure and the mechanical mechanism, and laying the foundation for improving the business efficiency of enterprises.

[0016] The technical solution of the present invention will be further described below with reference to the accompanying drawings, but the scope of protection claimed is not limited thereto; This invention provides a method for fitting and assembling printed circuit boards in narrow spaces, such as... Figures 1 to 3 As shown, it includes the following steps: Step 1: Provide circuit board 1; Step 2: Process the circuit board 1 from Step 1 to obtain the printed circuit board 5. The printed circuit board 5 is composed of multiple rigid plates 6 and multiple flexible plates 7, and the flexible plates 7 are connected between two adjacent rigid plates 6. Step 3: Fold, bend or twist the flexible plate 7 of the printed circuit board 5 in Step 2 to make a multi-fold circuit board, and make the length direction of the multi-fold circuit board coincide with the preset feature trajectory line. Step 4: Use fasteners to install the multi-fold circuit board from Step 3 into the narrow space.

[0017] By using the technical solution provided by this invention, flexible plates are set on the circuit board, so that the surface of the circuit board can be folded along the flexible plates while ensuring that it can support enough electronic components and wires, thus creating a three-dimensional multi-fold circuit board. The multi-fold circuit board can be more easily installed in the narrow space of electromechanical products, improving the assembly fit between the circuit board structure and the mechanical mechanism, and laying the foundation for improving the business efficiency of enterprises.

[0018] Specifically, in step one, multiple rigid regions 2, multiple flexible regions 3, and multiple cutting regions 4 are drawn on the surface of the circuit board 1. The multiple rigid regions 2 and multiple flexible regions 3 are distributed along the preset feature leads, and any flexible region 3 is connected between two adjacent rigid regions 2, and any rigid region 2 is connected between two adjacent flexible regions 3.

[0019] Furthermore, the preferred feature leads are multi-fold lines that bend and meander multiple times along the width direction of the circuit board 1. The rigid region 2, flexible region 3, and cutting region 4 are all rectangular in shape, with the length direction of the rigid region 2 coinciding with the width direction of the circuit board 1, and the length direction of the flexible region 3 coinciding with the length direction of the circuit board 1. In step one, the circuit board 1 is rectangular. Using the technical solution of this invention, the flexible plate 7 is made of polyimide and epoxy resin laminate. By setting the flexible plate 7, the original rectangular circuit board 1 can be folded, twisted, or bent along the flexible plate 7 to form a three-dimensional multi-fold circuit board. While ensuring sufficient surface area for electronic components and wires on the surface of the multi-fold circuit board, compared to the original rectangular circuit board, the multi-fold circuit board has a narrower width and a longer length, making it easier to install into electromechanical products. Furthermore, the manufacturing cycle of the multi-fold circuit board is shorter, facilitating rectification. When assembly errors or mistakes occur in the final assembly process of the electromechanical products produced by the enterprise, the rectification and correction time can be minimized, improving the enterprise's operating efficiency.

[0020] In addition, during step one, the distribution design of wires and electronic components is also carried out within rigid zone 2. Step one is performed on a computer using Altium Designer software.

[0021] Specifically, the feature trajectory line in step four can be a straight line segment, a multi-curved line segment, or a multi-bend straight line segment. The fasteners in step four include bolts, nuts, flat washers, and elastic washers.
