Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of copper-clad plate processing, in particular to a copper-clad plate laminating forming system based on a multi-region independent pressurizing structure. BACKGROUND

[0002] In the current high-speed development of the electronic information industry, as the core basic material of printed circuit boards, the quality and performance of copper-clad plates play a decisive role in the reliability and stability of printed circuit boards. The laminating forming process is a key link in the production process of copper-clad plates. In this process, pre-stacked prepregs of the same specification are laminated with copper foil under certain temperature and pressure to form copper-clad plates with specific electrical and mechanical properties.

[0003] In the laminating process of copper-clad plates, accurate positioning and fixing of raw materials is a key link to ensure product quality. The traditional limiting method mainly uses side extrusion single-dimension fixing strategy, which fixes the raw materials by setting fixed baffles on the side of the laminating equipment processing table. However, side extrusion limiting is prone to uneven stress on the raw materials, which may cause deviation or wrinkles during the laminating process, affecting the laminating effect. When the laminating pressure is large, the edges of the raw materials are prone to warping, misplacement and other problems, which may cause uneven thickness, circuit deviation and other quality problems in the finished copper-clad plate, seriously affecting the electrical performance and reliability of the product.

[0052] The principles and advantages of the copper clad laminate lamination system based on a multi-zone independent pressurization structure:

[0053] Raw material limiting process:

[0054] During the lamination pretreatment stage, the operator uses an external conveying device to transport the raw materials to be laminated (including pre-laminated semi-cured sheet substrates and copper foil) to the lamination processing table 2 in sequence according to the lamination process requirements. After the transportation is completed, the telescopic unit on the top of the support frame 3 cooperates with the guide mechanism to drive the lamination block 41 to feed in the direction of the raw materials. Docking plates 412 are set on both sides of the lamination block 41, and the docking plates 412 preferentially form initial contact with the abutment frame 61. As the lamination block 41 moves vertically downward, the docking plates 412 completely abut the top surface of the abutment frame 61. The abutment frame 61 can slide inside the processing table 2, and the compression spring between the docking plate 412 and the edge extension plate is a high-rigidity strong spring. When the abutment frame 61 contacts the docking plate 412, the initial contact force has not yet exceeded the pre-tightening threshold of the compression spring, so the docking plate 412 continues to drive the abutment frame 61 to move downward.

[0055] With the vertical movement of the abutment frame 61, the inclined surface thereof forms a line contact with the rollers 64 on the surface of the sliding block 62, and based on a force transmission mechanism, the abutment frame 61 generates a horizontal thrust directed to the center of the workbench to the rollers 64. The sliding block 62 drives the limiting block 52 to translate along the guide hole 51 to the direction of the raw material through the movable rods 63. Since the two movable rods 63 in the sliding block 62 are staggered in an up-down manner, interference during the movement of the limiting block 52 can be effectively avoided, and accurate positioning of the limiting block 52 to the raw material is ensured. The limiting block 52 is symmetrically arranged in four groups, and the guide hole 51 is arranged along the diagonal direction of the machining table 2. When two groups of abutment frames 61 are synchronously lowered, the four groups of limiting blocks 52 are synchronously fed along the guide hole 51 to the four corners of the raw material, realizing the positioning and constraint of the four edges of the raw material.

[0056] It is worth noting that a single group of limiting blocks 52 adopts an L-shaped structure design, and the side edge thereof forms an adaptive constraint when it is attached to the corner of the raw material. In addition, the two side surfaces of the limiting block 52 are machined with guide sliding slopes. The slopes form a dynamic guide structure during the feeding process of the limiting block 52. Even if there is a slight deviation in the initial positioning, dynamic calibration can be achieved through slope sliding, reducing the need for manual calibration and improving positioning accuracy and efficiency.

[0057] Locking process of the limiting block 52:

[0058] In the initial state, the locking block 534 is in the unlocked state, that is, the bottom surface of the locking block 534 is attached to the top surface of the machining table 2. At this time, the counterweight frame 532 is at the highest initial height. When the limiting block 52 completes the positioning and feeding along the guide hole 51 and reaches the position of the locking hole 531, the counterweight frame 532 slides downward along the guide groove on the surface of the limiting block 52 under the action of its own gravity. When the limiting block 52 moves to the position directly above the locking hole 531, the counterweight frame 532 drives the locking block 534 to be completely inserted into the locking hole 531, forming a mechanical interlocking structure and realizing the rigid positioning and locking of the limiting block 52. This locking mechanism can effectively prevent the raw material clamping stress from exceeding the standard due to over-positioning of the limiting block 52, and avoid quality defects caused by material deformation during the lamination process.

[0059] When the locking block 534 is completely inserted into the locking hole 531, the limiting block 52 and the adjusting part 6 form a rigid linkage. As the telescopic mechanism continues to drive the lamination block 41 to move downward, the contact force between the abutment frame 61 and the butt joint plate 412 gradually increases and exceeds the pre-tightening force threshold of the compression spring. At this time, the compression spring enters the elastic compression stage, and the lamination block 41 can continue to feed in the direction of the raw material, and then the auxiliary mechanism in the lamination block 41 performs lamination processing on the laminated raw material.

[0060] It is worth noting that the locking hole 531 adopts an asymmetric structural design, with a vertical positioning plane close to the raw material side and a guiding inclined surface away from the raw material side. When the locking block 534 is embedded in the locking hole 531, the positioning plane of the locking block 534 forms a surface contact constraint with the plane of the locking hole 531, and the limit block 52 is prevented from continuing to move through the principle of mechanical interference. When the limit needs to be released, the locking block 534 smoothly detaches from the locking hole 531 under the action of the component force generated along the inclined surface, realizing the rapid reset of the limit mechanism. This asymmetric locking structure realizes unidirectional rigid constraint and bidirectional motion control in the limit process through mechanical geometric design, effectively improving the stability and reliability of the lamination process.

[0061] Limit switching process:

[0062] As the counterweight frame 532 moves downward along the guide groove toward the locking hole 531, the push plate 533 on the counterweight frame 532 slides along the inclined surface of the movable frame 522. Through the motion conversion of the inclined surface mechanism, the movable frame 522 is driven to perform a linear feed motion along the through hole toward the raw material, and the outer elastic member is subjected to tensile deformation. During this process, the lever mechanism 526 in the movable hole synchronously drives the abutment plate 525 to perform a slight displacement away from the raw material, so that a controllable gap is formed between the side wall of the limit block 52 and the edge of the raw material. At the same time, the roller 523 in the movable frame 522 extends and forms a line contact constraint with the corresponding side wall of the raw material, realizing the conversion from the initial surface contact limit to the line contact limit. This conversion mechanism effectively avoids adhesive overflow and contamination of the limit component during the lamination process by reducing the actual contact area between the limit structure and the raw material, thereby reducing the frequency of equipment maintenance.

[0063] During the reset phase after the lamination operation is completed, when the telescopic assembly drives the laminating block 41 upward and away from the workpiece, the limiting unit 5 and the adjusting unit 6 perform the reset action. As the limiting block 52 moves in the opposite direction along the guide hole 51, the gear 527 at the end of the roller 523 meshes with the rack 528 on the inner wall of the through-hole, driving the roller 523 to rotate. Simultaneously, the protrusion 529 inside the movable frame 522 creates a scraping action against the outer circumference of the roller 523, removing any residual adhesive from the surface of the roller 523 through mechanical friction. This ensures the cleanliness of the roller 523 surface and prevents residual adhesive from affecting the accuracy of subsequent lamination operations.

[0064] The present invention adopts the adjusting portion 6 and the limiting portion 5, which has the following advantages:

[0065] Advantage one, when the laminating part 4 moves downward, the adjusting part 6 is triggered to act, and the limiting block 52 is driven to slide along the guide hole 51 to the four corners of the raw material. The limiting block 52 is designed in an L shape, and the inner side abutting plate 525 is attached to the edge of the raw material through an elastic element, and three-dimensional positioning is realized by using mechanical limiting principle, eliminating the risk of raw material deviation. Through the four limiting blocks 52 distributed along the center circle of the processing table 2, independent limiting of the four corners of the raw material is formed, avoiding the uneven stress problem caused by traditional side extrusion.

[0066] Advantage two, the limiting block 52 adopts an L-shaped structure, and the two side surfaces are processed with guide sliding slope surfaces. During the feeding process of the limiting block 52, the slope surfaces form a dynamic guide structure, so that even if there is a slight deviation in the initial positioning, dynamic calibration can be realized through slope sliding, reducing the need for manual calibration and improving the positioning accuracy and efficiency.

[0067] Advantage three, the counterweight frame 532 in the locking part 53 is attached to the movable frame 522 through the push plate 533, and when the limiting block 52 is in place, the locking block 534 is inserted into the locking hole 531 to form rigid locking. The combined effect of gravity and slope friction ensures that the limiting block 52 remains fixed during the entire laminating process. This design can effectively prevent the raw material clamping stress from exceeding the standard due to over-positioning of the limiting block 52, avoid material deformation during the laminating process due to excessive stress, and thus reduce the occurrence of quality defects.

[0068] Advantage four, when the traditional surface contact limiting occurs, the large-area contact between the limiting block 52 and the edge of the raw material may block the overflow of the overflow glue of the semi-solid sheet during heating, causing the overflow glue to accumulate between the limiting block 52 and the raw material, and forming adhesion after cooling. The linear contact design of the roller 523 reduces the contact area, allowing the overflow glue to flow out along the linear gap between the roller 523 and the edge of the raw material, avoiding local glue accumulation. The overflow glue can freely overflow onto the surface of the processing table 2, rather than being trapped between the limiting block 52 and the raw material, thereby reducing the adhesion between the edge of the raw material and the limiting block 52 after laminating, and reducing the risk of copper foil tearing caused by adhesion during product peeling.

[0069] Advantage five, during the resetting stage after the completion of the laminating operation, the gear 527 at the end of the roller 523 is engaged with the rack 528 on the inner wall of the through hole to drive the rotation of the roller 523. At the same time, the protrusion 529 inside the movable frame 522 rubs against the outer circumferential surface of the roller 523, removing the residual adhesive on the surface of the roller 523 through mechanical friction effect, ensuring the cleanliness of the surface of the roller 523 and avoiding affecting the precision of subsequent laminating operations.

[0070] The sixth advantage is that the locking hole 531 adopts an asymmetric structure, and the side close to the raw material is a vertical positioning plane, and the side far from the raw material is a guide inclined plane. When the locking block 534 is embedded into the locking hole 531, the positioning plane forms a surface contact constraint with the plane of the locking hole 531, and the displacement of the limiting block 52 is prevented. When the limiting is released, the locking block 534 is separated from the locking hole 531 under the action of the inclined plane component force. Through mechanical geometric design, one-way rigid constraint and two-way motion control of the limiting process are realized, and the stability and reliability of the laminating process are improved.
