Description

Technical Field

[0001] The present invention relates to the technical field of copper clad laminate lamination, and in particular to a multi-layer co-extruded copper clad laminate lamination system based on an aligned structure. Background Art

[0002] Copper-clad laminate (CCL) is a sheet material made by impregnating electronic fiberglass cloth or other reinforcing materials with resin, coating one or both sides with copper foil, and then heat-pressing. It acts as the "foundation" of electronic circuits, providing support and electrical connections for the various electronic components on a printed circuit board (PCB). CCL is the core substrate material for PCBs. Its manufacturing process involves laminating multiple layers of material, which are then cured by heat and pressure using a heating plate.

[0003] In the prior art, lamination equipment for multi-layer copper clad laminates mostly uses a manual method of placing the multi-layer copper clad laminates layer by layer, and then inserting positioning pins into corresponding positioning holes to achieve loading and alignment operations. Manual loading and alignment operations are inefficient, especially for thicker copper clad laminates, which require high handling strength. Manual operations are subject to inevitable errors, and alignment errors can lead to internal layer offsets in the final product, causing signal transmission abnormalities or even short circuits, affecting product quality and reliability. Summary of the Invention

[0030] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0031] The present invention will be further described below with reference to the embodiments.

[0032] Example:

[0033] See also Figures 1-9 The present invention provides a technical solution: a multi-layer co-extruded copper clad laminate system based on an aligned structure, comprising:

[0034] The placement portion 1 includes a workbench 11, which is fixedly connected to a support plate 13 via a supporting column 12 provided on its upper surface. There are multiple supporting columns 12. The upper surface of the workbench 11 is fixedly connected to a side panel 14. There are two side panels 14, which are symmetrically distributed on both sides of the supporting column 12. The side panels 14 are slidably connected to a positioning member 15 for clamping an external copper-clad laminate via an electric slide rail 141 provided on the side of the side near the supporting column 12.

[0035] The pressing part 2 includes a frame 21 fixed to the upper surface of the workbench 11, and the frame 21 is slidably connected to a pressing plate 23 via a lifting rod 22 provided on the lower surface thereof;

[0036] Among them, the positioning member 15 includes a sliding seat 151 that is slidably connected to the inside of the electric slide rail 141. The sliding seat 151 is arranged in several groups in the vertical direction, and each group of sliding seats 151 is provided with two. The two sliding seats 151 are symmetrically distributed on both sides of the supporting column 12. The sliding seat 151 is slidably connected to the connecting column 152 through a sliding groove opened therein. The side of the connecting column 152 away from the sliding seat 151 is fixedly connected to a pressure plate 153, and a spring 154 is sleeved on the circumferential outer surface of the connecting column 152.

[0037] The heights of the multiple support columns 12 are designed to be gradually varying, with the lowest column 12 on the side closest to the frame 21 and the highest column 12 on the side further away from the frame 21. The support plate 13 is connected to a ball bearing 131, which contacts the lower surface of the external copper-clad laminate, through a rolling groove on its upper surface. The highest point of the ball bearing 131 on the upper surface of the frontmost support plate 13 is slightly higher than the upper surface of the workbench 11.

[0038] The pressure plate 153 is rotatably connected to a connecting rod 155 on one side close to the sliding seat 151. A sliding cavity 1511 is provided on the outer surface of the sliding seat 151. A placement cavity 1512 connected to the interior of the sliding cavity 1511 is provided inside the sliding seat 151. The outer end of the connecting rod 155 extends into the interior of the sliding cavity 1511 and is fixedly connected to a rotating block 156.

[0039] An arc groove 1513 is provided on the inner wall surface of the sliding cavity 1511, and an arc strip 1561 is fixedly connected to the outer surface of the circumference of the rotating block 156, which slides in contact with the inner wall of the arc groove 1513. The sliding seat 151 is rotatably connected to a rotating tooth 157 mounted on the outer surface of the connecting rod 155 on one side close to the pressure plate 153. The rotating tooth 157 is slidably connected to the outer surface of the connecting rod 155 through a protrusion provided on the inner wall surface. The diameter of the placement cavity 1512 is larger than the diameter of the sliding cavity 1511.

[0040] The arc groove 1513 is close to the placement cavity 1512 and adopts a flared design. The outer surface of the arc strip 1561 is

[0041] The entire arc strip 1561 can be designed as a curved arc path composed of multiple bead-shaped protrusions that fit the inner wall surface of the arc groove 1513, and the bead-shaped protrusions and the inner wall surface of the arc groove 1513 are both smooth in design, with low friction.

[0042] The upper surface of the pressing plate 23 is fixedly connected to an L-shaped rod 24, and the outer end of the L-shaped rod 24 is fixedly connected to a gear rod 25. The gear rod 25 is rotatably connected to a pawl 251 through a rotating shaft arranged inside it. The outer surface of the rotating shaft is sleeved with a torsion spring 252 connected to the inside of the pawl 251. The outer surface of the gear rod 25 is fixedly connected to a limiting plate 253 that fits in contact with the upper surface of the pawl 251. In the initial state, under the action of the torsion spring 252, the upper surface of the pawl 251 fits in contact with the lower surface of the limiting plate 253. There are multiple pawls 251.

[0043] The upper surface of the side plate 14 is slidably connected to a lifting plate 16, and the lower surface of the lifting plate 16 is fixedly connected to a rack 161 meshing with the outer surface of the rotating tooth 157. Several groups of racks 161 are provided on the lower surface of the lifting plate 16. The number of racks 161 is the same as the number of sliding seats 151. The racks 161 near the front side are longer, and the racks 161 near the rear side are shorter. The racks 161 as a whole adopt the same structural design as the gear rod 25. The outer surface of the racks 161 is provided with a pawl 251, a torsion spring 252 and a limit plate 253 for driving the rotating tooth 157 to rotate in one direction.

[0044] The workbench 11 is slidably connected to the compression column 17 via a vertical groove provided on the upper surface thereof. An elastic member 171 connected to the lower surface of the compression column 17 is provided at the bottom of the inner wall of the vertical groove.

[0045] The process of aligning and loading multiple layers:

[0046] In actual applications, a circuit board is composed of multiple copper-clad laminates, dielectric layers, and other layers. Loading is completed using a conveying device such as an external robotic arm, and multiple layers of laminates to be laminated are placed simultaneously on the upper surface of a pallet 13 in order (the width of the pallet 13 is smaller than the width of the laminates). The top layer is placed on the upper surface of the pallet 13 farthest from the rack 21 (the rear side), and the bottom layer is placed on the upper surface of the pallet 13 closest to the rack 21 (the front side). The remaining intermediate layers are placed in order. The height of the supporting column 12 farthest from the rack 21 (the rear side) is the highest, and the heights of the remaining supporting columns 12 are gradually lowered, and the distances between two adjacent supporting columns 12 are equal.

[0047] The positioning member 15 is provided with multiple groups of sliding seats 151 , which are arranged in an array in the vertical direction. Each group of sliding seats 151 can correspond to a layer of layer boards. Each group is provided with two sliding seats 151 , which are symmetrically distributed on both sides of the supporting column 12 .

[0048] In the initial state, the positioning member 15 is located near the supporting column 12. The upper group of sliding seats 151, which slide in the electric slide rail 141, slides to both sides of the rearmost supporting column 12. The second upper group of sliding seats 151 slides to both sides of the second supporting column 12 from the back to the front. The remaining sliding seats 151 are arranged in sequence, with the top group of sliding seats 151 sliding to both sides of the frontmost supporting column 12. The multiple groups of pallets 13, shelves, and sliding seats 151 are stacked in a stepped manner. The lifting plate 16 is initially in an ascending state. Multiple groups of racks 161 are fixedly connected to the lower surface of the lifting plate 16. The heights of the multiple groups of racks 161 also adopt a gradient design. The racks 161 at the rear are lower, while the racks 161 at the front are higher. The lowest point of the racks 161 is higher than the upper surface of the upper sliding seat 151 (this does not affect the movement of the sliding seat 151 within the electric slide rail 141). The rack 161 and the gear rod 25 adopt the same structural design. In this state, one rack 161 corresponds to a set of sliding seats 151 one by one. The outer surface of the rack 161 close to the rotating tooth 157 is also rotatably connected to the pawl 251 through the rotating shaft.

[0049] In this state, the distance between the outer surface of the sliding seat 151 and the pressure plate 153 is relatively close, the rotating block 156 is inside the placement cavity 1512, the outer surface of the arc strip 1561 does not contact the inner wall of the arc groove 1513, the spring 154 is in a compressed state, and the distance between the two pressure plates 153 distributed on the left and right in each group is the largest, which is greater than the width of the layer plate, and the positioning member 15 is in a contracted state as a whole.

[0050] The driving base provided next to the side plate 14 drives the lifting plate 16 and the rack 161 to descend. For example, the right positioning member 15 in each group has the pawl 251 on the surface of the rack 161 located in front of the rotating tooth 157 in the positioning member 15. During the descent, the pawl 251 on the outer surface of the rack 161 is in a horizontal position under the action of the torsion spring 252, and the upper surface of the rack 161 is in contact with the limit plate 253. The outer surface of the rack 161 is provided with a plurality of ratchets 251, which can drive the rotating tooth 157 to rotate counterclockwise. During the descending process of the rack 161, the ratchets 251 engage with the tooth grooves on the surface of the rotating tooth 157 one by one, driving the rotating tooth 157 to rotate counterclockwise around its own axis. Since the circumferential inner surface of the rotating tooth 157 is fixedly connected with a protrusion embedded in the outer surface of the connecting rod 155, the rotation of the rotating tooth 157 will drive the connecting rod 155 to rotate counterclockwise synchronously. Correspondingly, during this process, the rotating block 156 also rotates counterclockwise in the placement cavity 1512.

[0051] During the rotation of the rotating block 156, the arc bar 1561 slides against the inner wall surface of the placement cavity 1512 close to one end of the pressure plate 153 until it reaches the outward expansion slot of the arc groove 1513 at the outer end of the arc bar 1561. Under the action of the counterclockwise rotating tooth 157, the arc bar 1561 enters the interior of the sliding cavity 1511 and fits against the inner wall of the arc groove 1513. The rack 161 no longer slides downward. The compression force of the spring 154 is released. The spring 154 is set to be strong. Under the action of the spring 154, the pressure plate 153 moves toward the side close to the support plate 13. The entire arc strip 1561 can be designed with a curved arc path composed of multiple bead-shaped protrusions that fit the inner wall surface of the arc groove 1513. The outer surface of the bead-shaped protrusions and the inner wall surface of the arc groove 1513 are both smooth and have low friction. When the spring 154 is released, the rotating block 156 and the connecting rod 155 move synchronously to the left under the action of the pressure plate 153, and the rotating block 156 and the rotating tooth 157 rotate counterclockwise during the movement.

[0052] During the rotation of the rotating tooth 157, the rack 161 remains stationary. After the tooth groove of the rotating tooth 157 is in contact with the outer end of the pawl 251, the pawl 251 is forced to rotate clockwise around the shaft by a certain angle, and the torsion spring 252 sleeved on the outer surface of the shaft is in a compressed state. The side of the pressure plate 153 close to the support plate 13 adopts a segmented design, with the upper half adopting an inclined surface design and the lower half adopting a vertical surface design. The vertical surface is used to clamp the side wall of the layer. The pressure plate 153 is expanded outward under the action of the spring 154. The vertical surfaces of the pressure plates 153 on the left and right sides simultaneously mate with the side walls of the layer, achieving the center alignment of the layer. Multiple sets of positioning members 15 in the expanded state simultaneously achieve the center positioning of the multi-layer layer, and the multi-layer layer achieves the left and right alignment action. The driving base drives the lifting plate 16 to rise and reset, and the pawl 251 on the rack 161 swings clockwise around the shaft to a certain angle, and the torsion spring 252 is compressed. During this process, the rotating tooth 157 is not affected, and the pressure plate 153 still maintains the clamping action on the layer board.

[0053] The layer board is still placed on the upper surface of the support plate 13, and the electric slide rail 141 in the side plate 14 drives the positioning piece 15 to move toward the pressing part 2. During this process, the lower surface of the layer board contacts the circumferential outer surface of the ball 131, and the two produce rolling friction. The contact area is small, and the friction force on the lower surface of the layer board is small, which avoids obvious scratches, burrs or local thinning on the copper foil surface due to lateral pulling, thereby ensuring the integrity of the circuit pattern.

[0054] Under the action of the electric slide rail 141, multiple groups of sliding seats 151 are moved to the bottom of the frame 21 until the front side edges of the multi-layer boards between the positioning parts 15 are in contact with the outer surface of the compression column 17. The multiple groups of sliding seats 151 continue to move forward a small distance to align the multiple boards in the front and rear directions, and their front sides are in the same vertical plane and are in contact with the outer surface of the compression column 17. At this time, the multiple groups of sliding seats 151 are also completely overlapped in the vertical direction.

[0055] The process of hot pressing multi-layer laminates:

[0056] Initially, the press plate 23 is at a higher position within its travel range. After the multi-layered plate is positioned below the frame 21 under the action of the positioning member 15, the hydraulically driven lifting rod 22 below the frame 21 is activated to move downward, and the press plate 23, which is fixedly connected to the output end of the lifting rod 22, moves downward synchronously. Under the action of the press plate 23, the L-shaped rod 24 drives the gear rod 25 to slide toward the positioning member 15 below.

[0057] During this process, the positioning member 15 remains in the expanded state, stably clamping the multiple layers above the workbench 11 until a pawl 251 located at the bottom of the outer surface of the gear rod 25 approaches the outer surface of the rotating tooth 157. Taking the positioning member 15 on the right side as an example, the pawl 251 on the outer side of the gear rod 25 is located behind the rotating tooth 157. During the descent of the gear rod 25, the pawl 251 engages with the tooth grooves on the surface of the first rotating tooth 157, driving the rotating tooth 157 to rotate clockwise around its own axis. Since the inner surface of the circumference of the rotating tooth 157 is fixedly connected to a protrusion embedded in the outer surface of the connecting rod 155, the rotation of the rotating tooth 157 will drive the connecting rod 155 to rotate clockwise synchronously. Correspondingly, during this process, the rotating block 156 also rotates clockwise in the placement cavity 1512. The pawl 251 on the outer surface of the gear rod 25 can drive the rotating tooth 157 to rotate clockwise by more than 180 degrees.

[0058] During the clockwise rotation of rotating block 156, the outer surface of curved strip 1561 slides against the inner wall of arc groove 1513, driving rotating block 156 as a whole toward the right side of placement chamber 1512 until the outer surface of curved strip 1561 clears the inner wall of arc groove 1513 and enters placement chamber 1512. As the clockwise rotation continues, the raised outer end of curved strip 1561 on the outer surface of rotating block 156 comes into contact with the inner wall of placement chamber 1512 near pressure plate 153. Curved strip 1561 temporarily locks rotating block 156 against the inner wall of placement chamber 1512. Accordingly, connecting rod 155 and pressure plate 153 also move closer to placement chamber 1512, minimizing the distance between pressure plate 153 and the outer surface of sliding seat 151. Spring 154 is compressed again, increasing the distance between the two pressure plates 153 in each group, and the upper positioning member 15 is deployed. Since the pressing plates 153 on the left and right sides move outward at the same time, the distance between the two pressing plates 153 is greater than the width of the layer plate, and the layer plate slides downward under the action of gravity using the clamping force.

[0059] The layer plate at the top (first layer plate) slides down to the upper surface of the layer plate (second layer plate) between the second group of positioning members 15. Since the outer surface of the pressure plate 153 away from the sliding seat 151 adopts a segmented design, the lower half adopts a vertical surface design to achieve clamping of the layer plate from the left and right sides, and the upper half of the pressure plate 153 adopts a slope design. When the group of positioning members 15 (first positioning members 15) located above is locked to the expanded state under the action of the gear rod 25, the first layer plate falls vertically onto the sloped surfaces of the two pressure plates 153 in the second group of positioning members 15 (second positioning members 15) from the top.

[0060] The pressing plate 23 continues to move downward, and the pawl 251 on the outer surface of the gear rod 25 contacts the outer surface of the rotating tooth 157 in the second positioning member 15, and repeats the above action to drive the rotating tooth 157 to rotate clockwise. The arc bar 1561 causes the rotating block 156, the connecting rod 155 and the pressure plate 153 to gradually shrink, and the inclined surface distance of the upper half of the outer surface of the two pressure plates 153 in the second positioning member 15 gradually increases. The left and right sides of the lower surface of the first layer of plate contact the inclined surfaces of the two pressure plates 153 in the second positioning member 15, and the lower surface of the first layer of plate moves vertically to fit with the upper surface of the second layer of plate. Under the action of the inclined surface, the two sides of the first layer of plate and the second layer of plate are completely aligned.

[0061] At this point, in the second positioning member 15, the rotating block 156 enters the interior of the placement cavity 1512 under the action of the arc groove 1513, and the second positioning member 15 is also locked to the retracted state under the action of the arc strip 1561. The two pressure plates 153 in the second positioning member 15 simultaneously expand outward, and the first layer and the second layer simultaneously fall between the pressure plates 153 in the next positioning member 15 (the third positioning member 15). The gear rod 25 continues to move downward following the pressing plate 23 and gradually puts the third positioning member 15 in the expanded state. The above process is repeated, so that multiple layers gradually fit with the upper surface of the next layer from top to bottom, thereby achieving alignment and fitting of multiple layers. Multiple groups of positioning members 15 are locked in the retracted state during the downward pressure of the pressing plate 23, so that when the subsequent pressure plates 153 slide to the initial position (on both sides of the corresponding support plate 13), they still remain in the retracted state to avoid interference with the layers.

[0062] After the multiple layers of laminates are aligned and stacked, the pressing plate 23 presses the stacked laminates together to form a whole. As the pressing plate 23 moves downward, the lower surface of the pressing plate 23 contacts the upper surface of the compression column 17, driving the compression column 17 to slide downward, compressing the elastic member 171. The elastic member 171 preferably uses a compression spring. The compression column 17 can always provide limiting support during the stacking of multiple laminates. An empty slot is provided on the upper surface of the workbench 11 at the vertical projection of the rack rod 25 and the rack 161. When the pressing plate 23 presses the multiple layers of laminates together, the lower end of the rack rod 25 enters the empty slot to prevent collision.

[0063] In summary, the laminate lamination equipment has the following advantages:

[0064] Advantage 1: The top layer is placed on the rearmost support plate 13, the bottom layer is placed on the frontmost support plate 13, and the middle layers are arranged in sequence, with the height difference of the supporting columns 12, forming a clear layered structure, providing a foundation for subsequent alignment. The loading and alignment of the multiple layers of the next circuit board can be completed while the previous circuit board is being pressed, reducing production waiting time and eliminating the need to stack multiple layers vertically below the pressing plate 23, thereby improving production efficiency.

[0065] Advantage 2: During the pre-loading layer alignment process, when the rack 161 descends, the pawl 251 drives the rotating gear 157 to rotate, driving the connecting rod 155 and the rotating block 156, so that the pressure plate 153 moves toward the support plate 13 under the release force of the spring 154. The vertical surfaces of the left and right pressure plates 153 clamp the side walls of the layer to achieve center alignment in the left and right directions. The multiple racks 161 are designed with a gradient height (low on the back and high on the front). When descending, they only drive the rotating gear 157 of the corresponding layer to rotate, avoiding interference between the positioning members 15 on different layers. Ensure that the positioning members 15 of each layer perform the clamping action independently in sequence, improve the stability of the system, enable each layer of the layer to be aligned independently, avoid position deviation when multiple layers of plates are stacked, and improve the overall alignment accuracy. Even if the lifting plate 16 is reset, the positioning member 15 remains in the expanded state, and the pressure plate 153 clamps the two sides of the layer to prevent the plate from loosening during movement.

[0066] Advantage 3: Before hot pressing, the positioning members 15 are in an expanded state, stably clamping the multiple layers above the workbench 11, ensuring that the layers are positioned stably and will not shift during the descent of the pressing plate 23. The descent of the pressing plate 23 drives the gear rod 25 to move, and the pawls 251 on the outer surface of the gear rod 25 engage with the transfer teeth 157 of the layer-by-layer positioning members 15, driving the multiple groups of positioning members 15 to retract layer by layer from top to bottom, allowing the layers to slide downward under the action of gravity, achieving layer-by-layer release and ensuring the stability of the layers during the release process. In this state, the positioning members 15 are tightly engaged with the inner wall of the placement cavity 1512 through the curved bars 1561 and locked in the retracted state, ready for the next movement to the sides of the support plate 13 to clamp the layers.

[0067] Advantage 4: The upper half of the pressure plate 153 is an inclined surface, and the lower half is a vertical surface. The vertical surface is used to clamp the side walls of the layers. When the layers fall, the inclined surface of the pressure plate 153 can guide them to align with the edges of the lower layers (for example, when the first layer falls on the second layer, the inclined surface ensures that the left and right edges overlap). No additional guide structure is required, and the vertical alignment of multiple layers of layers is automatically completed by the mechanical structure.

[0068] Advantage 5: Copper-clad laminates are thick and heavy. If they are only moved horizontally to align multiple layers, the upper and lower layers will rub against each other. Since the copper foil on the surface of the copper-clad laminate is usually thin, this friction can cause microscopic scratches or burrs on the copper foil surface. Scratches become weak points during circuit conduction, increasing resistance or causing short circuit risks. For delicate circuits, it can also damage the integrity of the circuit pattern. In addition, the friction caused by the horizontal movement between the two layers can generate metal debris, resin particles, or fiber dust, which can remain between the layers. After lamination, these contaminants can form void cores, resulting in reduced insulation between the layers or causing long-term reliability issues such as leakage due to moisture. The gear rod 25 moves downward, allowing the multiple groups of positioning members 15 to unfold layer by layer, and the inclined surface of the pressure plate 153 is used to guide the upper layer of the layer, so that the multi-layer boards are vertically and accurately aligned to avoid mutual friction; and when the layer materials are moved, the lower surface contacts the ball 131 on the support plate 13, and rolling friction replaces sliding friction. The contact area is small and the friction force is low, which can prevent the layers from causing scratches, burrs or local thinning on the copper foil surface due to mutual friction, thereby ensuring the integrity of the circuit pattern.

[0069] Advantage 6: Multiple laminates are aligned horizontally by the pressing plate 153, and moved forward and backward by the sliding seat 151, allowing the front ends of the laminates to align with the compression pillars 17. This achieves multi-dimensional positioning, ensuring that the laminates are in the same vertical plane before lamination, and improving overall accuracy after lamination. The positioning member 15 can accommodate laminates of varying widths within a certain range, offering a wide range of applicability.

[0070] Advantage 7: The number of sliding seats 151 in the positioning member 15 can be adjusted according to the number of layers of the layer board. The gradient design of the bearing column 12 and the rack 161 can be expanded to multiple layers accordingly, with strong compatibility and applicable to the production of circuit boards with different layer numbers and specifications.
