Description

Technical Field

[0001] The utility model relates to the technical field of circuit board manufacturing, and particularly relates to a plate arranging auxiliary machine. Background Art

[0002] In the context of the rapid evolution of the electronics industry, the manufacturing technology of multi-layer circuit boards has become a key factor driving the innovation of high-tech products. In the traditional manufacturing process, the transformation from single-layer boards to multi-layer structures, especially the tight interlayer bonding of Core (core board), prepreg (PP), and copper foil through vacuum lamination technology, is the core step to ensure the high performance and high reliability of circuit boards. Although vacuum lamination technology has been widely used in the production of multi-layer circuit boards to utilize high temperature and pressure to melt the PP material and achieve effective bonding between the core board and copper foil, there are still many bottlenecks in its pre-material preparation and lamination process. Especially in the manual or semi-automatic board stacking process, it not only takes time and effort but also easily introduces human errors, such as interlayer alignment deviation, bubble residue, etc., which will directly affect the electrical performance and mechanical strength of the final product.

[0003] In the production process of traditional multi-layer circuit boards, a large amount of manual labor is often relied on, especially in the stacking process of core boards, prepregs, and copper foils. This manual operation method is not only inefficient, limited by the differences in manual skills, but also prone to problems such as stacking misalignment and bubble inclusion. In particular, for copper foils with a small thickness, during the manual laying operation, the copper foil is prone to wrinkles, resulting in an uneven surface, seriously affecting the yield and electrical performance of the circuit board. Although there are some automated or semi-automated devices on the market to assist in the stacking operation of multi-layer circuit boards, these devices generally have problems such as poor adaptability, complex operation, and high maintenance costs. For example, some devices cannot effectively cope with the elastic deformation of copper foil materials, resulting in uneven laying and affecting subsequent lamination operations.

[0035] In the context of the rapid evolution of the electronics industry, the manufacturing technology of multilayer circuit boards has become a key factor driving the innovation of high-tech products. In the traditional manufacturing process, the transformation from single-layer boards to multilayer structures, especially the tight interlayer bonding of Core (core board), prepreg (PP), and copper foil through vacuum lamination technology, is the core step to ensure the high performance and high reliability of circuit boards. Although vacuum lamination technology has been widely used in the production of multilayer circuit boards to utilize high temperature and pressure to melt the PP material and achieve effective bonding between the core board and copper foil, there are still many bottlenecks in its preliminary material preparation and lamination process. In particular, the manual or semi-automatic board stacking process is not only time-consuming and laborious but also prone to human errors, such as interlayer alignment deviation and bubble residue. These problems will directly affect the electrical performance and mechanical strength of the final product.

[0036] In the production process of traditional multilayer circuit boards, a large amount of manual labor is often relied on, especially in the stacking process of core boards, prepregs, and copper foils. This manual operation method is not only inefficient, limited by the differences in manual skills, but also prone to problems such as stacking misalignment and bubble inclusion. In particular, for copper foils with a small thickness, during the manual laying operation, the copper foil is prone to wrinkles, resulting in an uneven surface, seriously affecting the yield and electrical performance of the circuit board. Although some automated or semi-automated devices have emerged in the market to assist in the stacking operation of multilayer circuit boards, these devices generally have problems such as poor adaptability, complex operation, and high maintenance costs. For example, some devices cannot effectively handle the elastic deformation of copper foil materials, resulting in uneven laying and affecting subsequent lamination operations.

[0037] Therefore, as Figure 1 and Figure 2As shown in the figure, the present utility model provides a platen auxiliary machine, which includes a workbench 100, a laying assembly 200 installed on the workbench 100, and a driving assembly installed on the workbench 100. Among them, the laying assembly 200 includes a sliding seat 210, an unwinding motor, a copper foil reel 220, a tension roller 230, and a pushing roller 240. The sliding seat 210 is slidably installed on the workbench 100. The unwinding motor, the copper foil reel 220, the tension roller 230, and the pushing roller 240 are all installed on the sliding seat 210 and are located above the workbench 100. Specifically, the unwinding motor is placed inside the sliding seat 210, and a power shaft 280 located outside the sliding seat 210 is connected to the driving shaft of the unwinding motor. Specifically, the copper foil reel 220 is installed on the power shaft 280. Driven by the unwinding motor, the power shaft 280 and the copper foil reel 220 rotate together. In addition, the copper foil reel 220 winds a copper foil sheet 300. The pushing roller 240 is located below the tension roller 230. The open end of the copper foil sheet 300 is wound around the tension roller 230 and reversely wound to the other side of the pushing roller 240. In application, the driving assembly is connected to and drives the laying assembly 200 to move linearly forward. The unwinding motor is connected to and drives the copper foil reel 220 to rotate, and the copper foil is wound around the tension roller 230 to lay the copper foil forward onto the workbench 100. In further application, the driving assembly is connected to and drives the laying assembly 200 to move linearly backward. The unwinding motor is connected to and drives the copper foil reel 220 to rotate, and the side wall of the copper foil is pushed by the pushing roller 240 to lay the copper foil backward onto the workbench 100. Optionally, the driving assembly includes a linear module (not shown in the figure). The sliding seat 210 is installed at the output end of the linear module. A common linear module adopts a motor and a lead screw drive structure, which can accurately control the linear movement of the sliding seat 210. By adopting a stable and programmable linear drive method, the movement control of the sliding seat 210 is more accurate and fast, improving the automation level and intelligence degree of the equipment, facilitating the realization of variable movement speed control, and adapting to more diverse production requirements. For example, when the operator presses the operation button, the driving assembly drives the laying assembly 200 to lay the copper foil sheet 300 forward. Then, the operator places the pp board, the core board, and the pp board stacked on the copper foil sheet 300. Next, when the operator presses the operation button again, the driving assembly drives the laying assembly 200 to lay the copper foil sheet 300 backward. It is easy to understand that during the forward laying and the backward laying, the driving assembly needs to drive the copper foil reel 220 to rotate along the side facing the tension roller 230 to release the copper foil.

[0038] It should be noted that by setting the laying component 200 and combining it with a precise driving component, the precise laying of the copper foil in both forward and reverse directions is achieved. When used in conjunction with manually placing the core board and pp board on the workbench 100, the operation is convenient. The copper foil can smoothly cover the core board and the pp board without wrinkles, which also improves the material utilization rate and the continuity of manual operations. Moreover, through the coordinated action of the unwinding motor, the tension roller 230, and the pushing roller 240, the stable control of the copper foil tension is ensured, avoiding the problem of material deformation caused by uneven tension, and laying a solid foundation for the subsequent vacuum lamination process.

[0039] Referring again to Figure 1 and Figure 2 , the tension roller 230 is swingably arranged on the sliding seat 210, which can better play a tensioning role on the copper foil sheet 300, improving the adaptability and accuracy of the laying of the copper foil sheet 300, reducing the problems of material deformation or uneven laying caused by uneven tension, and thus improving the quality and production efficiency of the multi-layer circuit board. Specifically, the sliding seat 210 is equipped with a swing arm 250. One end of the swing arm 250 is rotatably arranged on the sliding seat 210, and the other end is hinged to the tension roller 230. Thus, the tension roller 230 can rotate around the connection point of the swing arm 250 and the sliding seat 210. For example, an extension rod extending along the thickness direction of the swing arm 250 is fixedly connected to the outer side wall of the swing arm 250. The extension rod is inserted into the sliding seat 210 and is rotatably matched with the sliding seat 210. Thus, the tension roller 230 can rotate around the center line of the extension rod. Or, the sliding seat is fixedly connected with a fixed rod, and a slot hole is arranged on the outer side wall of the swing arm. The fixed slot is placed in the slot hole and is slidably matched with the slot hole (not shown in the figure). Thus, the tension roller can swing. It is easy to understand that when the copper foil sheet 300 is wound around the tension roller 230, it will exert a pressure on the tension roller 230. For example, when the copper foil sheet 300 released by the rotation of the copper foil supply reel 220 becomes longer, the pressure on the tension roller 230 becomes smaller. When the copper foil supply reel 220 rotates in the direction away from the unwinding direction, it will recover the copper foil sheet 300, and the pressure on the tension roller 230 becomes larger. Furthermore, the tension roller 230 swings adaptively under the action of the force to drive the copper foil sheet 300 to be in a tensioned state and make its surface flat.

[0040] In some embodiments, there are two swing arms 250, and a balance roller 260 is connected between the two swing arms 250. The balance roller 260 is located at one end of the connection between the swing arm 250 and the sliding seat 210 away from the tension roller 230. Referring to the seesaw structure, thus, during the tensioning process, the two sides of the swing arm 250 are evenly stressed, preventing skew or over-tensioning, and improving the stability of the mechanical system and the uniformity of copper foil laying. In addition, by replacing the balance roller 260 with different weights, the swinging performance of the tension roller 230, such as the swinging amplitude, can be adjusted.

[0041] In some applications, the unwinding motor is suitable for driving the copper foil material wheel 220 to rotate along the side away from the tensioning roller 230, and cooperates with the tensioning roller 230 to tension the copper foil, thereby optimizing the release tension control of the copper foil, ensuring that the copper foil will neither relax due to too low tension nor be damaged due to too high tension during the laying process, and improving the continuity and accuracy of the copper foil laying. Specifically, when laying the copper foil 300 on the front side, the unwinding motor first drives the copper foil material wheel 220 to rotate along the side facing the tensioning roller 230 to release the copper foil 300. After a period of time, the unwinding motor drives the copper foil material wheel 220 to rotate along the side away from the tensioning roller 230 to shrink the copper foil 300. As a result, the overall effect of the copper foil 300 laying operation on the front side is better.

[0042] Refer to Figure 2 In some embodiments of the utility model, the sliding seat 210 is connected to a limiting roller 270, and the limiting roller 270 is located on the swing path of the swing arm 250, which effectively limits the movement range of the swing arm 250, avoids the risk of mechanical collision or excessive swing, and improves the safety and stability of the equipment operation. At the same time, it also helps to maintain the positioning accuracy of the tensioning roller 230, thereby improving the reliability and efficiency of the copper foil laying operation.

[0043] like Figure 3 As shown, in some embodiments of the utility model, there are two laying components 200 and two driving components, and the laying components 200 are arranged one-to-one with the driving components, so that the plate arrangement auxiliary machine can perform two independent laying operations at the same time, and adopts a dual feeding setting. The operator can conveniently change materials for one group of laying operations without stopping the other group, thereby ensuring the continuity of production and significantly improving production efficiency.

[0044] Refer to Figure 3 In some embodiments of the utility model, the workbench 100 is fixedly mounted with a linear guide rail 110, and the sliding seat 210 is fixedly mounted with a slider, and the slider and the linear guide rail 110 slide in cooperation, ensuring that the linear motion of the sliding seat 210 is stable and accurate, improving the overall positioning accuracy and motion smoothness of the equipment, reducing mechanical wear, extending the service life of the equipment, and also facilitating the maintenance and adjustment of the equipment. Specifically, the length direction of the linear guide rail 110 is parallel to the length direction of the workbench 100, optimizing the spatial layout of the equipment and reducing the occupation of the working space.

[0045] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
