Description

Technical Field

[0001] This application relates to the field of integrated circuit manufacturing technology, and in particular to a production equipment for a multilayer printed circuit board with an embedded radio frequency 6G communication filter. Background Technology

[0002] With the development of 6G communication technology, radio frequency filters, as core components of high-frequency signal processing, need to be embedded inside multi-layer printed circuit boards to reduce signal loss and improve integration.

[0003] In the existing technology, in the production of this type of multilayer printed circuit board, after the filter is embedded in the core inner layer board, it needs to be transferred, and then PP sheets are placed on the top and bottom sides of the inner layer board by hand before entering the lamination operation. This process is fragmented, and the whole process from board supply to board removal is time-consuming, which cannot meet the needs of large-scale mass production and limits production efficiency.

[0004] To address these issues, we propose a production equipment for multilayer printed circuit boards with embedded RF 6G communication filters. Summary of the Invention

[0005] The purpose of this application is to address the technical problem in existing multilayer printed circuit board (PCB) manufacturing processes where the embedding of filters and the placement of PP sheets are separate processes, resulting in limited production efficiency. Compared to existing technologies, this application provides a production device for multilayer PCBs with embedded 6G radio frequency communication filters, comprising: A board feeding mechanism is used for horizontally inputting an inner layer board, the inner layer board having pre-machined embedded grooves that match the filter and undergoing browning treatment; The tablet pressing mechanism is used to clamp the filter from the feeding mechanism and press it down into the inner recess. The transfer mechanism is used to horizontally receive the inner layer plate from the plate supply mechanism and transfer it to the area below the tablet pressing mechanism; The insert mechanism is used to transfer the inner layer plate that has been pressed into the filter from the transfer mechanism, and insert the lower PP plate and the upper PP plate into the two sides of the inner layer plate respectively by flipping action. The ejection mechanism is used to horizontally output the inner layer plates with the lower and upper PP sheets inserted on both sides.

[0006] Furthermore, the transfer mechanism includes a support base plate horizontally fixed on the frame. The support base plate is disposed below the pressing mechanism. A slide table is slidably connected to the bottom of the support base plate near the inserting mechanism. The two ends of the slide table extend out from both sides of the support base plate and are fixed with rotating seats. Each rotating seat plate is rotatably connected with a flipping side plate. The two sets of flipping side plates are symmetrically arranged. A horizontal feeding plate is slidably connected to the side of the support base plate near the feeding mechanism. The width of the horizontal feeding plate plate is smaller than the width of the inner layer plate. The flip side plate and the horizontal feeding plate move synchronously towards or away from each other on the support base plate. The end of the flip side plate near the horizontal feeding plate is fixed with a rotating shaft that matches the rotating seat. An eccentric slider is fixed on the rotating shaft. Guide side plates are also fixed on both sides of the support base plate. The guide side plates are provided with guide grooves that cooperate with the eccentric sliders. The guide grooves are used to drive the flip side plate to move away from the horizontal feeding plate to the maximum stroke. When the flip side plate rotates in the direction close to the horizontal feeding plate, the entire flip side plate flips.

[0007] Furthermore, a double-ended lead screw is rotatably connected to the bottom of the support base plate. The double-ended lead screw is driven by a servo motor. A first nut seat that cooperates with the double-ended lead screw is provided on the slide table. A second nut seat that cooperates with the double-ended lead screw is fixed to the bottom of the horizontal feeding plate. The bottom of both ends of the slide table is fixed with a first slider. The frame is fixed with side slide rails that cooperate with the first sliders on both sides of the support base plate. Two sets of middle slide rails are symmetrically fixed on the top of the support base plate. The bottom of the horizontal feed plate is fixed with a second slider that cooperates with the middle slide rails.

[0008] Furthermore, the top of the flip side plate is provided with a support groove, the distance between the opposite groove edges of the two sets of flip side plates is equal to the width of the inner layer plate, and the opposite side of the two sets of flip side plates is also provided with a mating side edge, the relative distance between the mating side edges of the two sets of flip side plates is equal to the width of the horizontal feeding plate. The horizontal feeding plate has a second stop edge fixed on the side away from the input direction of the inner layer plate. The top of the horizontal feeding plate is provided with several third suction holes. The flipping side plate has a first stop edge fixed on the side away from the input direction of the inner layer plate. When the flipping side plate moves close to the horizontal feeding plate to the minimum stroke, the first stop edge and the second stop edge are flush. The bottom of the support groove and the top surface of the horizontal feeding plate are on the same horizontal plane. At this time, the horizontal feeding plate is used to support the middle area of ​​the inner layer plate, and the support groove is used to support the two side areas of the inner layer plate, so as to realize the overall support of the inner layer plate. The support groove is also provided with an inlet on the side opposite to the input direction of the inner layer plate; The top of the flip-up side plate is provided with a first adsorption hole.

[0009] Furthermore, the insert mechanism includes a drive shaft, which is disposed between the ejection mechanism and the transfer mechanism and is driven to rotate on the frame by a stepper motor. Several flip trays are fixed on the drive shaft at equal angles, and the width of the flip trays is equal to the width of the horizontal feed plate. The flipping tray has a third stop edge fixed on the side away from the drive shaft, and the side of the flipping tray used to support the inner layer plate is also provided with a second suction hole. The drive shaft is also fixed with bowl-shaped baffles on both sides of the flip tray, and the minimum distance between the two sets of bowl-shaped baffles is equal to the width of the inner layer plate.

[0010] Furthermore, the number of the flipping trays is in sets, the maximum flipping angle of the flipping side plate is forty-five degrees, and the drive shaft rotates at fixed angles of forty-five degrees. When the flip tray is rotated and inserted between the two sets of flip side plates, the plane of the flip tray with the second suction hole and the plane of the flip side plate with the first suction hole are located on the same plane, and the third stop edge abuts against the bottom edge of the inner layer plate that flips and tilts with the flip side plate.

[0011] Furthermore, a first conveyor belt and a second conveyor belt are respectively provided on the top two sides of the insert mechanism. The output ends of the first conveyor belt and the second conveyor belt are arranged opposite each other and inclined downwards. The first conveyor belt and the second conveyor belt are respectively used to transport the lower PP sheet and the upper PP sheet between adjacent flipping pallets.

[0012] Furthermore, the tablet pressing mechanism includes an XYZ linear module fixed on the frame, and a clamping fixture is fixed to the output end of the XYZ linear module.

[0013] Furthermore, the feeding mechanism includes several equidistant first long shaft roller groups and two symmetrically arranged first short shaft roller groups. The relative distance between the two first short shaft roller groups is equal to the width of the horizontal feeding plate, and the distance between the rollers on the two first short shaft roller groups is less than the width of the inner layer plate. The plate ejection mechanism includes several equidistantly arranged second long-axis roller groups and two symmetrically arranged second short-axis roller groups. The relative distance between the two groups of second short-axis roller groups is equal to the width of the flipping tray, and the distance between the rollers on the two groups of second short-axis roller groups is less than the width of the inner layer plate.

[0014] Compared to existing technologies, the advantages of this application are: This invention achieves the transfer of the inner layer plate between the plate supply mechanism and the insert mechanism by adjusting the horizontal feeding plate and the flipping side plate in the transfer mechanism to move closer or further apart. During this process, the pressing mechanism is connected to realize the embedding action of the filter, and the insert mechanism is connected to complete the transfer and PP sheet insertion process synchronously. The entire process of plate supply, embedding, transfer, inserting, and plate removal is completed without manual transfer. The process connection time is short, which meets the needs of large-scale production and has high production efficiency. Attached Figure Description

[0017] The embodiments will be described clearly and completely with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments in this application without creative effort are within the scope of protection of this application.

[0018] Example: This invention provides a production equipment for a multilayer printed circuit board with an embedded RF 6G communication filter. Please refer to [link / reference]. Figure 1 - Figure 12 This application uses the frame 9 as the installation reference and integrates a plate feeding mechanism 1, a pressing mechanism 2, a transfer mechanism 3, a plate insertion mechanism 4, a plate ejection mechanism 5, a first conveyor belt 6, and a second conveyor belt 7 to collaboratively complete the processing of embedding the filter 82 in the inner layer plate 8 and bonding the PP sheets on both sides. The filter 82 is a 6G radio frequency communication filter, including: The board feeding mechanism 1 horizontally inputs the pre-processed inner layer board 8 with embedded grooves 81 and browning treatment, providing a qualified base material for subsequent processing; The tablet pressing mechanism 2, which is not shown in the diagram of the supporting feeding mechanism, is linked with the equipment to clamp the filter 82 and precisely press it down into the inner groove 81 of the inner layer plate 8; The transfer mechanism 3 receives the inner layer plate 8 conveyed by the plate supply mechanism 1, completes horizontal transfer and angle flipping, and connects the pressing and inserting processes. The insert mechanism 4 receives the inner layer plate 8 with the filter 82 embedded in it from the transfer mechanism 3, and inserts the lower PP sheet 61 and the upper PP sheet 71 in stages on both sides of the inner layer plate 8 through a rotation action. The ejection mechanism 5 horizontally outputs the inner layer board 8 after the PP sheet insertion is completed, and transfers it to the subsequent lamination process.

[0019] For more specific details, please refer to [the relevant documentation]. Figure 4 - Figure 7 The transfer mechanism 3 includes a support substrate 31, which is horizontally fixed to the frame 9 and serves as a support structure for the transfer mechanism 3. Its position is directly below the pressing mechanism 2 to ensure the vertical alignment of the filter 82 when it is embedded. The guide side plate 32 is symmetrically fixed on both sides of the support base plate 31, and the guide groove 321 is opened on the plate to provide trajectory constraints for the flipping action of the flipping side plate 33. Two sets of symmetrically arranged flip side plates 33 are provided, and a support groove 333 is provided on the top. The support groove 333 matches the two sides of the inner layer plate 8 and is used to support the two side edges of the inner layer plate 8. A first stop 332 is provided on the side of the flip side plate 33 away from the feeding direction to limit the end point of the inner layer plate 8. A rotating shaft 335 is fixed at one end near the horizontal feeding plate 34. An eccentric slider 336 is sleeved on the rotating shaft 335. The eccentric slider 336 is embedded in the guide groove 321 to realize the linkage of displacement and flipping. Specifically, there is a height difference between the start and end points of the guide groove 321. If the axial distance between the eccentric slider 336 and the rotating shaft 335 is L, then the height difference between the start and end points of the guide groove 321 is L*sin45°. The top of the flip side plate 33 is also provided with a first adsorption hole 331, which fixes the inner layer plate 8 by vacuum adsorption; the two sets of flip side plates 33 are provided with mating side edges 337 on the opposite side, and the distance between the two sets of mating side edges 337 matches the width of the horizontal feeding plate 34 to ensure that the two are seamlessly connected. The horizontal feeding plate 34 is slidably connected to the side of the support substrate 31 near the feeding mechanism 1. The bottom is connected to the middle slide rail 38 of the support substrate 31 through the second slider to achieve horizontal sliding. The side of the horizontal feeding plate 34 away from the feeding direction is provided with a second stop 341. When it is flush with the first stop 332, it forms a complete inner layer plate 8 limiting structure. The top of the horizontal feeding plate 34 is provided with a third adsorption hole 343. The slide table 35 is slidably connected to the bottom of the support base plate 31 near the insert mechanism 4. Both ends extend out of the support base plate 31 and fix the rotating seat 351. The rotating seat 351 is rotatably engaged with the rotating shaft 335 of the flip side plate 33. The bottom of the slide table 35 is engaged with the side slide rail 37 of the frame 9 through the first slider 352 to ensure smooth sliding. The double-ended lead screw 36 is rotatably connected to the bottom of the support base plate 31 and is driven by a servo motor. The threads at both ends of the screw body are rotated in opposite directions and respectively cooperate with the first nut seat 353 of the slide table 35 and the second nut seat 342 of the horizontal feed plate 34 to realize the synchronous approach or departure of the slide table 35 and the horizontal feed plate 34.

[0020] Please refer to this first. Figure 8 The insert mechanism 4 includes a drive shaft 44, which is rotatably connected to the frame 9 and located between the plate ejection mechanism 5 and the transfer mechanism 3. It is driven to rotate by a stepper motor. In this embodiment, there are 6 sets of flip trays 41, which are evenly fixed on the drive shaft 44 at equal angles. The width of the flip tray 41 is the same as that of the horizontal feeding plate 34. A third stop 411 is provided on the side away from the drive shaft 44 for edge limiting when receiving the inner layer plate 8. The receiving surface of the flip tray 41 is provided with a second adsorption hole 42, which fixes the inner layer plate 8 by vacuum adsorption. Two sets of bowl-shaped baffles 43 are symmetrically fixed on the drive shaft 44, located on both sides of the flip tray 41, with the minimum spacing matching the width of the inner layer plate 8 to prevent the inner layer plate 8 from shifting laterally; Please refer to this first. Figure 1 The first conveyor belt 6 and the second conveyor belt 7 are respectively set on the top two sides of the insert mechanism 4, with their output ends facing each other and tilting downwards, respectively conveying the lower PP sheet 61 and the upper PP sheet 71 between adjacent flipping pallets 41.

[0021] Please refer to this first. Figure 12 The tablet pressing mechanism 2 includes an XYZ linear module 21 fixed to the frame 9 and a clamping fixture 22 at its output end. The XYZ linear module 21 achieves precise displacement in three-dimensional direction, and the clamping fixture 22 is used to stably clamp the filter 82 and press it down to embed it into the inner groove 81.

[0022] It should be noted that the feeding mechanism 1 consists of several equidistantly arranged first long-axis roller groups 11 and two symmetrical first short-axis roller groups 12. The relative distance between the two first short-axis roller groups 12 is consistent with the width of the horizontal feeding plate 34, so that the horizontal feeding plate 34 can be moved between the two first short-axis roller groups 12. The distance between the rollers on the two first short-axis roller groups 12 is less than the width of the inner layer plate 8, ensuring that when the horizontal feeding plate 34 is moved between the two first short-axis roller groups 12, the rollers on the first short-axis roller groups 12 abut against the bottom sides of the inner layer plate 8 and still have the conveying function. The unloading mechanism 5 consists of several equidistantly arranged second long-axis roller groups 51 and two symmetrical second short-axis roller groups 52. The relative distance between the two second short-axis roller groups 52 is consistent with the width of the flipping pallet 41, so that the flipping pallet 41 can rotate between the two second short-axis roller groups 52. The roller distance between the two second short-axis roller groups 52 is less than the width of the inner layer plate 8, ensuring that the rollers abut against the bottom sides of the inner layer plate 8 and still have the conveying function.

[0023] In the process of using this invention, the inner layer board 8, which has been pre-processed with embedded grooves 81 and has undergone browning treatment, is horizontally conveyed by the first long-axis roller group 11 and the first short-axis roller group 12 of the board feeding mechanism 1. Since the spacing of the first short-axis roller group 12 matches the horizontal feeding plate 34, please refer to [link to relevant documentation]. Figure 9 and Figure 10When the horizontal feeding plate 34 and the flipping side plate 33 move away from each other, the horizontal feeding plate 34 moves between the two sets of first short shaft roller groups 12. Since the inner layer plate 8 conveyed by the first long shaft roller group 11 is transferred to the horizontal feeding plate 34 through the relay of the first short shaft roller group 12, when the inner layer plate 8 touches the second stop edge 341, this process can be monitored by a displacement sensor. Specifically, the displacement sensor is a photoelectric sensor used to sense the position of the edge of the inner layer plate 8. When the inner layer plate 8 is detected to be in position, the third adsorption hole 343 starts vacuum adsorption to adsorb the inner layer plate 8. At the same time, the horizontal feeding plate 34 and the flipping side plate 33 move closer to each other. The horizontal feeding plate 34 supports the inner layer plate 8 and inserts the two sides of the inner layer plate 8 into the support groove 333 along the inlet 334 of the flipping side plate 33.

[0024] After the inner layer plate 8 is in place, the first adsorption hole 331 starts vacuum adsorption, and the third adsorption hole 343 maintains vacuum adsorption, thereby fixing the inner layer plate 8 on the horizontal feeding plate 34 and the support groove 333. At this time, the horizontal feeding plate 34 supports the middle of the inner layer plate 8, and the support groove 333 supports both sides, achieving stable support in the whole area and avoiding deformation of the inner layer plate 8. At this time, the XYZ linear module 21 of the tablet pressing mechanism 2 drives the clamping fixture 22 to move to the feeding mechanism, clamps the 6G RF filter 82, moves to the top of the inner embedded groove 81, and presses down to embed the filter 82 into the inner embedded groove 81. The supporting substrate 31 provides stable support for the embedding action. After the embedding is completed, the clamping fixture 22 is reset and waits for the next embedding action.

[0025] After the filter 82 is embedded, the third adsorption hole 343 closes the vacuum adsorption, while the first adsorption hole 331 maintains vacuum adsorption. The servo motor drives the double-headed lead screw 36 to rotate, which, through the first nut seat 353 and the second nut seat 342, drives the slide table 35 and the horizontal feeding plate 34 to move away synchronously along the side slide rail 37 and the middle slide rail 38, respectively. During this process, the horizontal feeding plate 34 moves towards the plate feeding mechanism 1 to receive the next inner layer plate 8; the flipping side plate 33 moves towards the insert mechanism 4. During the displacement, the eccentric slider 336 of the flipping side plate 33 slides along the guide groove 321 of the guide side plate 32. Due to the change in the height difference of the guide groove 321, the eccentric slider 336 drives the rotating shaft 335 to rotate, causing the flipping side plate 33 to flip towards the horizontal feeding plate 34. Finally, the flipping angle stabilizes at 45°, and the inner layer plate 8 tilts synchronously with the flipping side plate 33.

[0026] The stepper motor of the insert mechanism 4 drives the drive shaft 44 to rotate 45°, causing a set of flipping trays 41 to be inserted between two sets of flipping side plates 33. At this time, the plane of the flipping tray 41 with the second suction hole 42 and the plane of the flipping side plate 33 with the first suction hole 331 are on the same plane, and the third stop 411 abuts against the bottom edge of the inclined inner layer plate 8. At this time, the first suction hole 331 releases the vacuum, the second suction hole 42 is activated, and the inner layer plate 8 is smoothly transferred onto the flipping tray 41. The bowl-shaped baffle 43 restricts the inner layer plate 8 from both sides to prevent displacement.

[0027] As the drive shaft 44 continues to rotate 45°, it causes the inner layer plate 8 to flip. At the same time, the horizontal feeding plate 34 receives the next inner layer plate 8 and moves closer to the flipping side plate 33 again to perform the next cycle of mating action. Please refer to this first. Figure 11 When the flipping pallet 41 drives the inner layer plate 8 to flip upward, before reaching the highest point, the inner layer plate 8 adheres to the surface of the flipping pallet 41 due to gravity and the adsorption force of the second adsorption hole 42. At this time, the first conveyor belt 6 transports the PP sheet 61 between adjacent flipping pallets 41 carrying the inner layer plate 8. When the flipping pallet 41 drives the inner layer plate 8 to flip past the highest point, the second adsorption hole 42 removes the adsorption force. During the flipping process, the inner layer plate 8 and the lower PP sheet 61 will move away from the supporting flipping pallet 41 due to gravity and deflect to the back of the next flipping pallet 41. At this time, the second conveyor belt 7 transports the upper PP sheet 71 between the inner layer plate 8 and the supporting flipping pallet 41. Because the output end of the conveyor belt is inclined, the upper PP sheet 71 naturally adheres to the surface of the inner layer plate 8 by gravity, achieving flat insertion.

[0028] It should be noted that, in this embodiment, a visual inspection device can be installed on the pressing mechanism 2 to monitor the embedding yield of the filter 82. When the detected defective product is detected, the first conveyor belt 6 and the second conveyor belt 7 of the corresponding stage will no longer transport PP sheets. The inner layer plate 8 transported separately on the unloading mechanism 5 is easy to identify and can be directly rejected by the robotic arm, so as to improve the lamination yield.

[0029] After the PP sheet is inserted, the inner layer plate 8 rotates with the drive shaft 44 to the plate ejection mechanism 5. Since the vacuum of the second adsorption hole 42 has been released at this time, the two sides of the inner layer plate 8 with the PP sheet sandwiched between the upper and lower sides come into contact with the rollers of the second short shaft roller group 52. Using the conveying force of the rollers and the friction between the PP sheet and the browned inner layer plate 8, the inner layer plate 8 is horizontally output to the subsequent lamination process.

[0030] At the same time, the drive shaft 44 drives the next set of empty flip trays 41 to rotate to the receiving position. The slide table 35 of the transfer mechanism 3 and the horizontal feeding plate 34 move away from each other and reset synchronously, ready to receive the next inner layer plate 8 and enter the next production cycle.

[0031] This invention achieves the transfer of the inner layer plate 8 between the plate supply mechanism 1 and the insert mechanism 4 by moving the horizontal feeding plate 34 and the flipping side plate 33 closer or further apart in the transfer mechanism 3. During this process, the pressing mechanism 2 is connected to realize the embedding action of the filter 82, and the insert mechanism 4 is connected to complete the transfer and PP sheet insertion process. The entire process of plate supply, embedding, transfer, inserting, and plate removal is completed. The entire process does not require manual transfer, the process connection time is short, which meets the needs of large-scale production and has high production efficiency.

[0032] The above description is only the best implementation method adopted in this application in combination with current practical needs, but the scope of protection of this application is not limited thereto.
