Description

Technical Field

[0001] This utility model relates to the field of electronic circuit manufacturing technology, specifically to an auxiliary tooling for copper-clad laminate lamination that can accurately position prepreg. Background Technology

[0002] In the field of electronic circuit manufacturing, copper-clad laminate (CCL) is an important basic material, and its quality directly affects the performance of electronic products. During the lamination process, the precise positioning of the prepreg and the CCL is crucial; it is a key step in ensuring the quality of CCL lamination and guaranteeing the stability and reliability of electronic products.

[0003] Traditional copper-clad laminate (CCL) lamination auxiliary tooling has revealed numerous problems in practical applications. Positioning methods are often crude, relying on manual operation based on experience, making high-precision positioning difficult. This leads to frequent misalignment and displacement of the prepreg and CCL during lamination, severely impacting the electrical performance of the CCL, resulting in high defect rates and increased production costs. Furthermore, traditional tooling lacks flexibility, with cumbersome and complex adjustment processes requiring significant time and manpower, making it difficult to adapt to the production needs of different prepreg and CCL specifications. Facing the current trend of miniaturization and high performance in electronic products, higher demands are placed on CCL lamination quality and production efficiency; existing lamination auxiliary tooling can no longer meet the industry's needs. Utility Model Content

[0004] The purpose of this invention is to provide an auxiliary tooling for copper-clad laminate lamination that can accurately position prepreg sheets, so as to solve the problems mentioned in the background art.

[0005] The technical solution of this utility model is: a copper-clad laminate laminating auxiliary tooling for accurately positioning prepreg, comprising two sets of support columns, the upper ends of the two sets of support columns being fixedly connected to the same worktable, the surface of the worktable having two symmetrically arranged sliding grooves, the lower part of the worktable having two symmetrically arranged strip-shaped limiting plates, the lower surface of the support columns having two symmetrically arranged L-shaped sliding plates slidably connected, the side walls of the two L-shaped sliding plates having strip-shaped grooves, the side walls of the two strip-shaped limiting plates being fixedly connected to the same fixing plate, the surfaces of the two L-shaped sliding plates having two symmetrically arranged rotating rods rotatably connected, the upper ends of the two rotating rods being fixedly connected to L-shaped rotating plates.

[0006] Preferably, an electric push rod is fixedly connected to the lower surface of the fixed plate, and a fixed block is fixedly connected to the side wall of the L-shaped sliding plate on the left side, with the output end of the electric push rod fixedly connected to the side wall of the fixed block.

[0007] Preferably, a fixed round rod is fixedly connected to the lower surface of the support column, and a strip-shaped linkage plate is rotatably connected to the surface of the fixed round rod. Two symmetrically arranged connecting rods are rotatably connected to the surface of the strip-shaped linkage plate, and the other ends of the two connecting rods are rotatably connected to the inner wall of an adjacent L-shaped sliding plate.

[0008] Preferably, the lower surface of the L-shaped rotating plate is rotatably connected to two symmetrically arranged adjusting wheels, and the adjusting wheels are slidably connected to the surface of the worktable.

[0009] Preferably, the inner walls of the two L-shaped sliding plates are fixedly connected to two symmetrically arranged tension spring shells. The lower end of the rotating rod passes through the upper end of the tension spring shell and extends into the interior. A tension spring is fixedly connected to the surface of the tension spring shell, and the other end of the tension spring is fixedly connected to the inner wall of the tension spring shell.

[0010] Preferably, a support assembly is fixedly connected to the upper surface of the workbench, and a cylinder is fixedly connected to the upper surface of the support assembly.

[0011] Preferably, the two ends of the two strip-shaped limiting plates are fixedly connected to the side walls of the adjacent support columns, and the surface of the strip-shaped limiting plates is slidably connected to the inner wall of the strip groove.

[0012] This utility model provides an improved auxiliary tooling for copper-clad laminate lamination that can accurately position prepreg sheets. Compared with the prior art, it has the following improvements and advantages:

[0013] Firstly, this invention utilizes an electric push rod to drive an L-shaped sliding plate to slide on the lower surface of a support column, thereby rotating a rotating rod and an L-shaped rotating plate. Simultaneously, an adjusting wheel slides on the worktable surface, and in conjunction with the limiting action of the sliding groove and the strip-shaped limiting plate, precisely positioning the prepreg and copper-clad laminate in the appropriate positions. This precise positioning effectively reduces material offset and misalignment during lamination, ensuring a perfect fit between the copper-clad laminate and the prepreg, thus significantly improving the quality and stability of the laminated product.

[0014] Secondly, this invention incorporates a tension spring shell and a tension spring, which buffer and adjust the rotation of the rotating rod, making the L-shaped rotating plate rotate more smoothly and flexibly. Furthermore, the application of electric push rods and cylinders enables the entire positioning and lamination process to be completed automatically, reducing the difficulty and error of manual operation and improving work efficiency.

[0022] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0023] This utility model provides an improved auxiliary tooling for copper-clad laminate lamination that can accurately position prepreg sheets. The technical solution of this utility model is as follows:

[0024] like Figure 1 - Figure 4 As shown, the copper-clad laminate lamination auxiliary tooling for precisely positioning prepreg includes two sets of support columns 1. The upper ends of the two sets of support columns 1 are fixedly connected to the same worktable 2. The surface of the worktable 2 has two symmetrically arranged sliding grooves 3. The lower part of the worktable 2 has two symmetrically arranged strip-shaped limiting plates 4. The lower surface of the support column 1 is slidably connected to two symmetrically arranged L-shaped sliding plates 5. The side walls of the two L-shaped sliding plates 5 are each provided with strip-shaped grooves 6. The side walls of the two strip-shaped limiting plates 4 are fixedly connected to the same fixing plate 7. The surfaces of the two L-shaped sliding plates 5 are rotatably connected to two symmetrically arranged rotating rods 8. The upper ends of the two rotating rods 8 are fixedly connected to L-shaped rotating plates 9.

[0025] Furthermore, an electric push rod 10 is fixedly connected to the lower surface of the fixed plate 7, and a fixed block 11 is fixedly connected to the side wall of the left L-shaped sliding plate 5. The output end of the electric push rod 10 is fixedly connected to the side wall of the fixed block 11. The electric push rod 10 can precisely control the power output. By connecting with the fixed block 11, it can stably push the left L-shaped sliding plate 5 to move, thereby driving the movement of the relevant parts of the entire tooling. This enables precise adjustment of the tooling structure position, facilitating better positioning and fixing of the prepreg and copper-clad laminate during the lamination process, and improving positioning accuracy and operational convenience.

[0026] Furthermore, a fixed round rod 12 is fixedly connected to the lower surface of the support column 1. A strip-shaped linkage plate 13 is rotatably connected to the surface of the fixed round rod 12. Two symmetrically arranged connecting rods 14 are rotatably connected to the surface of the strip-shaped linkage plate 13. The other ends of the two connecting rods 14 are rotatably connected to the inner wall of the adjacent L-shaped sliding plate 5. When one side of the L-shaped sliding plate 5 moves under the action of the electric push rod 10, the linkage structure between the connecting rod 14 and the strip-shaped linkage plate 13 can drive the other side of the L-shaped sliding plate 5 to move synchronously in the opposite direction. This ensures the coordination and symmetry of the movement of the two sets of L-shaped sliding plates 5, so that the tooling always maintains a stable structural state during the adjustment process. This is beneficial for symmetrical and precise positioning of the prepreg and improves the lamination auxiliary effect.

[0027] Furthermore, the lower surface of the L-shaped rotating plate 9 is rotatably connected to two symmetrically arranged adjusting wheels 16. These adjusting wheels 16 are slidably connected to the surface of the worktable 2. The arrangement of the adjusting wheels 16 allows the L-shaped rotating plate 9 to move more smoothly on the surface of the worktable 2, reducing frictional resistance to its movement. This allows for more flexible and rapid response to tooling adjustments, improving the efficiency of tooling adjustments, reducing component wear, extending the tooling's service life, and contributing to efficient and precise positioning of the prepreg.

[0028] Furthermore, two symmetrically arranged tension spring shells 15 are fixedly connected to the inner walls of both L-shaped sliding plates 5. The lower end of the rotating rod 8 passes through the upper end of the tension spring shell 15 and extends into the interior. A tension spring 17 is fixedly connected to the surface of the tension spring shell 15, and the other end of the tension spring 17 is fixedly connected to the inner wall of the tension spring shell 15. The elasticity of the tension spring 17 enables the rotating rod 8 and the connected L-shaped rotating plate 9 to have the ability to automatically reset. After the tooling completes one positioning operation, when the external force is removed, the tension spring 17 can drive the L-shaped rotating plate 9 back to the initial position, facilitating the next positioning adjustment, improving the continuity and convenience of tooling operation, and also enhancing the stability and reliability of the tooling structure.

[0029] Furthermore, a support assembly 18 is fixedly connected to the upper surface of the workbench 2, and a cylinder 19 is fixedly connected to the upper surface of the support assembly 18. The output end of the cylinder 19 penetrates the surface of the support assembly 18 and extends into its interior. A square block 20 is fixedly connected to the output end of the cylinder 19. The cylinder 19 can provide stable and adjustable pressure, and the square block 20 can tightly press the prepreg and the copper-clad laminate together, meeting the pressure requirements of the lamination process. The support assembly 18 provides a stable mounting and support structure for the cylinder 19, ensuring the stability and accuracy of the pressing process, helping to improve the lamination quality, ensuring a good adhesion between the prepreg and the copper-clad laminate, and achieving precise lamination operation.

[0030] Furthermore, the two ends of the two strip-shaped limiting plates 4 are fixedly connected to the side walls of the adjacent support columns 1, and the surface of the strip-shaped limiting plates 4 is slidably connected to the inner wall of the strip-shaped groove 6. The cooperation between the strip-shaped limiting plates 4 and the strip-shaped groove 6 plays a role in limiting and guiding. During the movement of the L-shaped sliding plate 5, the strip-shaped limiting plates 4 restrict the movement trajectory of the L-shaped sliding plate 5, so that it can only slide along the direction of the strip-shaped limiting plates 4, ensuring the straightness and stability of the movement of the L-shaped sliding plate 5, thereby improving the accuracy of the tooling positioning, ensuring that the prepreg can be accurately positioned during the lamination process, and avoiding problems such as displacement.

[0031] Working principle: Initially, the prepreg and copper-clad laminate are placed on the workbench 2. The electric push rod 10 is activated, with its output end connected to the fixing block 11 on the side wall of the left L-shaped sliding plate 5. When the electric push rod 10 is working, it pushes the left L-shaped sliding plate 5 to slide along the lower surface of the support column 1. Due to the linkage between the strip linkage plate 13 and the connecting rod 14 rotatably connected to the fixed round rod 12, the right L-shaped sliding plate 5 slides synchronously in the opposite direction. At this time, the strip groove 6 on the side wall of the L-shaped sliding plate 5 slides along the strip limiting plate 4, which plays a limiting and guiding role. During the sliding process of the L-shaped sliding plate 5, it drives the rotating rod 8 rotatably connected to the surface to rotate. The L-shaped rotating plate 9 at the upper end of the rotating rod 8 rotates accordingly. The adjusting wheel 16 on the lower surface of the L-shaped rotating plate 9 slides on the surface of the workbench 2, assisting the L-shaped rotating plate 9 to rotate smoothly. The tension spring 17 inside the tension spring housing 15 connects the lower end of the rotating rod 8 to the inner wall of the tension spring housing 15, playing a buffering and adjusting role, making the L-shaped rotating plate 9 rotate more smoothly, thereby assisting in the fine-tuning and bonding of the prepreg and copper-clad laminate placed on the workbench 2, achieving precise positioning. After positioning is completed, the cylinder 19 is activated. The cylinder 19 is fixed on the support component 18, which is located on the upper surface of the workbench 2. The output end of the cylinder 19 passes through the support component 18 and connects to the square block 20, pressing down to perform lamination on the precisely positioned prepreg and copper-clad laminate, completing the entire lamination process.
