Description

Technical Field

[0001] This invention relates to the field of rigid-flex PCB processing technology, and in particular to a lamination apparatus and method for controlling the migration of residual adhesive at the interface in rigid-flex PCBs. Background Technology

[0002] Rigid-flex boards are made by laminating rigid and flexible circuit boards together. They inherit the excellent mechanical support of rigid circuit boards and the dynamic bending properties of flexible circuit boards. Lamination is a crucial process in the production of rigid-flex boards, which mainly uses high temperature and high pressure to firmly bond multiple layers of rigid and flexible materials together.

[0003] However, the following problems exist when laminating rigid-flex PCBs: under heating and pressurizing conditions, the semi-cured sheet or adhesive film at the interface of the boards may produce excessive resin overflow due to excessive fluidity, i.e., residual adhesive migration. The adhesive may migrate to non-bonded areas, such as the edge of the press plate, which may lead to product contamination or even defects such as short circuits. Therefore, this application proposes a lamination device and method for controlling the migration of residual adhesive at the interface of rigid-flex PCBs. Summary of the Invention

[0004] The purpose of this invention is to address the problem of adhesive migration to non-bonding areas in the prior art by proposing a lamination device and method for controlling the migration of residual adhesive at the interface in rigid-flexible laminates.

[0005] In a first aspect, the present invention provides a lamination device for controlling the migration of interfacial residual adhesive in a rigid-flexible laminate, comprising a processing table, a support plate threadedly connected to the top of the processing table, a housing fixedly connected to the top of the processing table, a cylinder mounted on the top of the housing, and a molding plate drivenly connected to the output end of the cylinder, and further comprising:

[0006] A connecting ring is rotatably connected to the top of the processing table. Multiple sets of fixing recesses are fixed to the top of the connecting ring. A square tube is fixed to the top of each set of fixing recesses. A square rod is slidably connected inside the square tube. A connecting rod is slidably connected inside the square rod. A connecting plate is fixed to the end of the connecting rod near the support plate. A sponge is fixed to the end of the connecting plate away from the connecting rod.

[0007] An inclined block is fixed to the end of the square rod away from the connecting rod. A displacement mechanism is provided on the periphery of the molding plate. When the molding plate moves upward, it drives the inclined block to move, so that the sponge is separated from the adhesion of the support plate.

[0008] The elastic mechanism, connected to the inclined block, is used to make the sponge adhere to the support plate when the displacement mechanism releases control of the inclined block;

[0009] The rotating mechanism, connected to the connecting ring, is used to control the rotation of the connecting ring, so that the sponge rotates along the outside of the tray to clean the residual adhesive generated during hot pressing.

[0010] Optionally, the displacement mechanism includes a horizontal plate, two sets of fixed rods, a side plate, an annular plate, and a guide rod. The horizontal plate is attached to the top of the molding plate. The two sets of fixed rods are respectively fixed to both sides of the bottom end of the horizontal plate. The side plate is fixed to the bottom end of the fixed rods. The annular plate is fixed to the side plate and is attached to the inclined block. The guide rod slides through the interior of the side plate and is fixed to the top of the processing table.

[0011] Optionally, the elastic mechanism includes a top plate and a spring, the top plate being fixed to the top end of the square tube, and the spring being fixed between the inclined block and the top plate.

[0012] Optionally, the rotating mechanism includes a motor, a spur gear, and an internal gear ring. The motor is installed inside the processing table, the spur gear is fixedly connected to the output end of the motor, and the internal gear ring is fixedly connected to the inner wall of the connecting ring, with the spur gear meshing with the internal gear ring.

[0013] Optionally, two sets of retaining plates are fixed to the end of the connecting plate away from the sponge. Each set of retaining plates has a retaining groove inside. A triangular block is set inside the retaining groove. An installation mechanism is set on the outside of the square rod. The installation mechanism is used to move the triangular block so that the triangular block is inside the retaining groove, thereby fixing the position of the connecting plate.

[0014] Optionally, the installation mechanism includes a guide plate, two sets of guide rods, an L-plate, and a spring. The guide plate is fixedly connected to the triangular block. Both sets of guide rods slide through the guide plate. The end of the guide rod away from the guide plate is fixedly connected to the outside of the square rod. The L-plate is fixedly connected to the end of the guide rod away from the square rod. The spring is fixedly connected between the square rod and the guide plate.

[0015] Optionally, a tension plate is fixedly connected to the outer side of the fixing rod, and a spring is fixedly connected between the tension plate and the processing table.

[0016] Optionally, the inclined block and the annular plate are made of polyoxymethylene.

[0017] Optionally, the sponge is made of high-density open-cell polyurethane material.

[0018] Secondly, the present invention provides a method for controlling the migration of interface residual adhesive in a rigid-flex plate, applied to a lamination apparatus for controlling the migration of interface residual adhesive in a rigid-flex plate as described in the first aspect, the method comprising the following steps:

[0019] S1. Place the sheet material and prepreg to be laminated on the surface of the pallet, and control the cylinder to move the molding plate downward to perform the lamination operation on the sheet material and prepreg.

[0020] S2. The control of the displacement mechanism is released when the molding plate moves down. The displacement mechanism then falls due to gravity. At this time, the compression of the inclined block by the displacement mechanism ends, and the elastic mechanism pulls the inclined block to move.

[0021] S3. The inclined block moves the connecting rod through the square rod, and the connecting rod moves the sponge through the connecting plate, so that the sponge fits against the outside of the tray and absorbs the glue that overflows and adheres to the edge of the tray.

[0022] Compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0023] This invention, through the structural design of a displacement mechanism and an elastic mechanism, enables the displacement mechanism to release the pressure on the inclined block during the pressing operation of the molding plate, while the elastic mechanism drives the sponge to adhere to the edge of the plate, forming a flexible sealing barrier that effectively prevents glue from overflowing and absorbs excess seepage. After the molding plate rises, the sponge is simultaneously withdrawn, realizing automated operation of spill suppression and cleaning.

[0024] Furthermore, the sponge is driven to move in a circular motion along the edge of the tray by a rotating mechanism to remove residual adhesive that overflows during the lamination process, effectively preventing adhesive from contaminating non-bonding areas. During the cleaning process, the high-density polyurethane sponge can also perform preliminary polishing on the edges of the board while rotating continuously, achieving efficient synergy between cleaning and surface treatment, and significantly improving the overall quality of the laminated products.

[0034] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0035] In the description of this invention, it should be understood that the terms "upper," "lower," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component positioned centrally in the connection.

[0036] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0037] like Figure 1 and Figure 2As shown, the present invention proposes a lamination device for controlling the migration of residual adhesive at the interface in a rigid-flexible laminate, comprising a processing table 1, which supports the components at the top. The top of the processing table 1 is threadedly connected to a support plate 2. During the lamination process, the sheet material to be laminated and the prepreg are first placed on the surface of the support plate 2 and aligned with the edge of the support plate 2. It should be noted that the laminate material and the prepreg in this embodiment are all circular structures. The support plate 2 is threadedly connected, which facilitates the replacement of support plates 2 of different sizes to adapt to rigid-flexible laminates of different sizes. The top of the processing table 1 is fixedly connected to a housing 3, and a cylinder 4 is installed on the top of the housing 3. The housing 3 serves as a protective element and supports the cylinder 4. The output end of the cylinder 4 is driven by a molding plate 5. When the cylinder 4 is running, it can drive the molding plate 5 to move downward, thereby cooperating with the sheet material and the prepreg aligned with the support plate 2 to be hot-pressed together to form a rigid-flexible laminate. It should be noted that the lamination process in this embodiment is all existing technology and is mature, and will not be elaborated further.

[0038] As one implementation method, such as Figure 3 - Figure 7As shown, the laminating device also includes a connecting ring 6 rotatably connected to the top of the processing table 1. The connecting ring 6 can rotate along the top of the processing table 1. Multiple sets of fixing recesses 7 are fixedly connected to the top of the connecting ring 6. When the connecting ring 6 rotates, it can also drive the multiple sets of fixing recesses 7 to rotate synchronously. A square tube 8 is fixedly connected to the top of each set of fixing recesses 7. The rotation of the fixing recesses 7 drives the square tube 8. A square rod 9 is slidably connected inside the square tube 8. A connecting rod 10 is slidably connected inside the square rod 9. The rotation of the square tube 8 can drive the square rod 9 and... The connecting rod 10 rotates, and a connecting plate 11 is fixedly connected to one end of the connecting rod 10 near the support plate 2. A sponge 12 is fixedly connected to the end of the connecting plate 11 away from the connecting rod 10, allowing the sponge 12 to move in a circular motion along the support plate 2. An inclined block 13 is fixedly connected to the end of the square rod 9 away from the connecting rod 10. A displacement mechanism is provided on the periphery of the molding plate 5. When the molding plate 5 moves upward, it drives the inclined block 13 to move, causing the sponge 12 to disengage from the support plate 2. In the initial state, the molding plate 5 drives the displacement mechanism to the extreme position of upward movement. At this time, the displacement mechanism... The inclined block 13 is in a compressed state and is located at the top of the inclined block 13. The elastic mechanism is connected to the inclined block 13. When the displacement mechanism releases its control over the inclined block 13, the sponge 12 adheres to the support plate 2, while the elastic mechanism is in a deformed and elastic state. When the cylinder 4 drives the molding plate 5 to move down for lamination, the control of the molding plate 5 on the displacement mechanism is released, and the displacement mechanism will fall naturally. The falling of the displacement mechanism ends the compression of the inclined block 13, and the elastic mechanism will pull the inclined block 13 towards the support plate 2. The movement of the inclined block 13 will... The square rod 9 moves along the inside of the square tube 8, and the square rod 9 also moves the connecting rod 10. The moving connecting rod 10 then moves the sponge 12 through the connecting plate 11, so that the sponge 12 is attached to the outside of the tray 2, that is, to the edge of the material to be pressed. It should be noted that the sponge 12 is slightly higher than the material to be laminated. Then, when the molding plate 5 presses the material on the surface of the tray 2, the sponge 12 and the edge of the tray 2 form a physical barrier to prevent the glue in this area from overflowing. At the same time, the glue that overflows under pressure will be absorbed by the sponge 12.

[0039] Furthermore, such as Figure 3 , Figure 4 and Figure 5As shown, the rotating mechanism in the laminating device is connected to the connecting ring 6 and is used to control the rotation of the connecting ring 6 so that the sponge 12 rotates along the outer side of the tray 2 to clean the residual adhesive generated during hot pressing. After the sponge 12 is attached to the outer side of the tray 2, the rotating mechanism runs. When the rotating mechanism runs, it drives the connecting ring 6 to rotate. The rotation of the connecting ring 6 drives the fixed concave block 7 to rotate. The rotation of the fixed concave block 7 drives the square tube 8 to rotate. The rotation of the square tube 8 drives the connecting plate 11 to rotate through the connecting rod 10, so that the sponge 12 moves in a circle along the tray 2. At this time, multiple sets of sponges 12 can wipe along the outer side of the tray 2 to wipe the adhesive overflowing during the lamination of the board evenly, thereby preventing the adhesive from migrating to the non-bonding area. In addition, the sponge 12 is made of high-density open-pore polyurethane material. This material is widely used in cleaning wipes, precision device cleaning and polishing pads. Therefore, when the sponge 12 rotates continuously, the edges of the board can also be simply polished.

[0040] As one implementation method, such as Figure 5 , Figure 6 and Figure 7 As shown, the displacement mechanism includes a horizontal plate 14, two sets of fixing rods 15, a side plate 16, an annular plate 17, and a guide rod 18. The displacement mechanism is described in detail below:

[0041] The horizontal plate 14 is attached to the top of the molding plate 5. Initially, the molding plate 5 and the horizontal plate 14 form a supporting state, that is, the molding plate 5 pushes the horizontal plate 14 upward. When the molding plate 5 moves downward, the pushing force on the horizontal plate 14 ends, and the horizontal plate 14 falls under the action of gravity. The two sets of fixing rods 15 are respectively fixed to both sides of the bottom end of the horizontal plate 14. The side plate 16 is fixed to the bottom end of the fixing rod 15. The annular plate 17 is fixed to the side plate 16, and the annular plate 17 is attached to the inclined block 13. At this time, the tension of the horizontal plate 14 on the fixing rod 15 ends, and the fixing rod 15 then... As the horizontal plate 14 moves downwards, the fixed rod 15 also moves downwards, causing the side plate 16 and the annular plate 17 to move downwards simultaneously. The downward movement of the annular plate 17 ends the compression of the inclined surface of the inclined block 13. The inclined block 13 then moves towards the support plate 2 under the action of the elastic mechanism, causing the sponge 12 to adhere to the outside of the support plate 2. It should be noted that the limit distance of the inclined block 13's movement is such that its inclined surface will not leave the control area contacted by the annular plate 17 when it moves upwards. The guide rod 18 slides through the interior of the side plate 16 and is fixed to the top of the processing table 1. The arrangement of the guide rod 18... The side plate 16 acts as a guide when it moves, ensuring that it moves vertically along the outside of the guide rod 18 to prevent wobbling. When the molding plate 5 finishes lamination and moves upward, it will contact the horizontal plate 14 again after moving a certain distance. The horizontal plate 14 will then be subjected to force and move upward, which in turn will drive the fixing rod 15 to move upward. The upward movement of the fixing rod 15 will then drive the annular plate 17 to move upward through the side plate 16. The upward movement of the annular plate 17 will then press the inclined surface of the inclined block 13 again. The inclined surface of the inclined block 13 will be subjected to force and move away from the support plate 2. The inclined block 13 moves in the opposite direction. The resetting mechanism will drive the connecting rod 10 to reset via the square rod 9. It should be noted that there is significant friction between the connecting rod 10 and the square rod 9. Therefore, when the square rod 9 resets, the friction force can drive the connecting rod 10 to reset. The resetting of the connecting rod 10 will then drive the sponge 12 to reset via the connecting plate 11, causing the sponge 12 to detach from its contact with the outer side of the tray 2, facilitating the loading and unloading of the board. The inclined block 13 and the annular plate 17 are made of polyoxymethylene, which has high rigidity and hardness, excellent wear resistance, and a low and stable coefficient of friction, making it suitable for the scenarios required in this implementation.

[0042] Furthermore, such as Figure 5 and Figure 7 As shown, the elastic mechanism includes a top plate 19 and a spring 20. The elastic mechanism is described in detail below:

[0043] The top plate 19 is fixed to the top of the square tube 8. When the annular plate 17 presses the inclined block 13, the inclined block 13 is in a direction away from the support plate 2. The spring 20 is fixed between the inclined block 13 and the top plate 19. At this time, the inclined block 13 will cooperate with the top plate 19 to pull the spring 20 to deform and generate elastic potential energy. After the annular plate 17 is released from the pressure on the inclined block 13, the spring 20 will release the elastic potential energy, thereby pulling the inclined block 13 to move towards the sponge 12. The sponge 12 finally adheres to the outside of the support plate 2.

[0044] Furthermore, such as Figure 3 As shown, the rotating mechanism includes a motor 21, a spur gear 22, and an internal gear ring 23. The rotating mechanism is described in detail below:

[0045] The motor 21 is installed inside the processing table 1. The spur gear 22 is fixedly connected to the output end of the motor 21. When the motor 21 runs, it drives the spur gear 22 to rotate. The internal gear ring 23 is fixedly connected to the inner wall of the connecting ring 6, and the spur gear 22 meshes with the internal gear ring 23. The rotation of the spur gear 22 will drive the internal gear ring 23 to rotate. The rotation of the internal gear ring 23 will eventually drive the connecting ring 6 to rotate, so that multiple sets of sponges 12 can perform wiping operations along the outer side of the tray 2.

[0046] As one implementation method, such as Figure 8 As shown, two sets of retaining plates 24 are fixed to the end of the connecting plate 11 away from the sponge 12. Each set of retaining plates 24 has a retaining groove 25 inside. A triangular block 26 is set inside the retaining groove 25. In the initial state, the triangular block 26 is inside the retaining groove 25. At this time, when the connecting rod 10 is moved out of the square rod 9, the retaining plate 24 will be blocked by the triangular block 26 and cannot be disassembled, thus realizing the function of fixing the connecting rod 10 to the square rod 9. This ensures that the connecting rod 10 will not detach from the square rod 9 when the sponge 12 is working. An installation mechanism is provided on the outside of the square rod 9. The installation mechanism is used to move the triangular block 26 so that the triangular block 26 is inside the retaining groove 25 and fixes the position of the connecting plate 11. When it is necessary to disassemble the sponge 12 for cleaning, it is only necessary to move the triangular block 26 by moving the installation mechanism. The triangular block 26 will detach from the retaining groove 25, and the retaining plate 24 can be moved so that the connecting plate 11 drives the connecting rod 10 to detach from the square rod 9, and the sponge 12 can be disassembled for cleaning.

[0047] Furthermore, such as Figure 8 As shown, the installation mechanism includes a guide plate 27, two sets of guide rods 28, an L-plate 29, and a spring 30. The installation mechanism is described in detail below:

[0048] The guide plate 27 is fixedly connected to the triangular block 26. When the connecting rod 10 is separated from the square rod 9, the guide plate 27 is moved towards the square rod 9. Both sets of guide rods 28 slide through the guide plate 27. The end of the guide rod 28 away from the guide plate 27 is fixedly connected to the outside of the square rod 9. The guide plate 27 will then move along the outside of the guide rod 28. The movement of the guide plate 27 will cause the triangular block 26 to disengage from the inside of the slot 25. At this time, the triangular block 26 stops blocking the slot plate 24, and the connecting rod 10 can be moved to separate the connecting rod 10 from the square rod 9. The L-plate 29 is fixedly connected to the end of the guide rod 28 away from the square rod 9. The spring 30 is fixedly connected to the square rod 9. Between the guide plate 27 and the guide plate 27, and when the guide plate 27 moves, the guide plate 27 will also squeeze the second spring 30, causing the second spring 30 to deform under force and generate elastic potential energy. After the guide plate 27 is released, the second spring 30 will release the elastic potential energy and push the triangular block 26 to reset. When the connecting rod 10 is installed into the square rod 9 next time, the clamping plate 24 will squeeze the inclined surface of the triangular block 26, and the triangular block 26 will deform under force. When the triangular block 26 and the slot 25 are on the same plane, the compression of the triangular block 26 by the clamping plate 24 ends, the second spring 30 will release the elastic potential energy, and the triangular block 26 will reset to be inside the slot 25, thereby realizing the function of quick installation of the connecting rod 10 and the square rod 9.

[0049] Furthermore, such as Figure 6 and Figure 7 As shown, a tension plate 31 is fixedly connected to the outer side of the fixed rod 15. In the initial state, the fixed rod 15 is at its maximum upward distance, and the fixed rod 15 simultaneously drives the tension plate 31 to its maximum upward position. A spring 32 is fixedly connected between the tension plate 31 and the processing table 1. The spring 32 is in a state of tensile deformation under the pull of the tension plate 31. When the fixed rod 15 moves down, the spring 32 can release elastic potential energy, pulling the tension plate 31 down. The tension plate 31 will then pull the fixed rod 15 down, avoiding instability due to gravity alone. With the elastic potential energy of the spring 32, it is ensured that the fixed rod 15 will not descend slowly due to excessive friction, thus accelerating the separation speed of the annular plate 17 and the inclined block 13.

[0050] A method for controlling the migration of residual adhesive at the interface in a rigid-flex plate, the method comprising the following steps:

[0051] S1. First, place the sheet material and prepreg to be pressed on the surface of the tray 2, and control the cylinder 4 to drive the molding plate 5 to move down to perform lamination on the sheet material and prepreg.

[0052] S2. Subsequently, the control of the displacement mechanism is released when the molding plate 5 moves down. The displacement mechanism then falls due to gravity. At this time, the compression of the inclined block 13 by the displacement mechanism ends, and the elastic mechanism pulls the inclined block 13 to move.

[0053] S3, the inclined block 13 drives the connecting rod 10 to move through the square rod 9, and the connecting rod 10 drives the sponge 12 to move through the connecting plate 11, so that the sponge 12 fits against the outside of the tray 2 and absorbs the glue that overflows and adheres to the edge of the tray 2.

[0054] In this embodiment, the sheet material and prepreg to be pressed are first placed on the surface of the tray 2 and aligned with the edge of the tray 2. Initially, the annular plate 17 presses the inclined surface of the inclined block 13, while the spring 20 is in a deformed state. Then, the cylinder 4 moves to drive the molding plate 5 downward, cooperating with the sheet material and prepreg on the aligned surface of the tray 2 for lamination. When the molding plate 5 moves downward, the horizontal plate 14 is no longer pushed by the molding plate 5, and the horizontal plate 14 will fall under the action of gravity. At this time, the tension of the horizontal plate 14 on the fixing rod 15 ends, and the fixing rod 15 moves downward with the horizontal plate 14. When the fixing rod 15 moves downward, the side plate 16 and the annular plate 17 move downward synchronously. The downward movement of the annular plate 17 ends the pressing on the inclined surface of the inclined block 13, and the spring 20 releases its elastic potential energy, pushing the inclined block 13 towards the sponge 12. The movement of the inclined block 13... The square rod 9 will move along the inside of the square tube 8, and the square rod 9 will also move the connecting rod 10. The moving connecting rod 10 will then move the sponge 12 through the connecting plate 11, so that the sponge 12 is attached to the outside of the tray 2, that is, to the edge of the material to be pressed. At this time, the motor 21 is started. When the motor 21 runs, it drives the spur gear 22 to rotate. The rotation of the spur gear 22 will drive the internal gear ring 23 to rotate. The rotation of the internal gear ring 23 will eventually drive the connecting ring 6 to rotate. The rotation of the connecting ring 6 will drive the fixing concave block 7 to rotate. The rotation of the fixing concave block 7 will then drive the square tube 8 to rotate. The rotation of the square tube 8 will then drive the connecting plate 11 to rotate through the connecting rod 10, so that the sponge 12 moves in a circle along the tray 2. At this time, multiple sets of sponges 12 can wipe along the outside of the tray 2, and wipe the glue overflowing during the lamination of the material evenly.

[0055] Initially, the triangular block 26 is inside the slot 25. When the connecting rod 10 is moved out of the square rod 9, the locking plate 24 is blocked by the triangular block 26 and cannot be disassembled. When the sponge 12 needs to be removed for cleaning, the guide plate 27 is moved towards the square rod 9. The movement of the guide plate 27 causes the triangular block 26 to disengage from the slot 25. At this point, the triangular block 26 stops blocking the locking plate 24, allowing the connecting rod 10 to be moved, separating it from the square rod 9. Furthermore, as the guide plate 27 moves, it also compresses the spring 30, causing the spring to... Spring 30 deforms under force, generating elastic potential energy. After the guide plate 27 is released, spring 30 releases its elastic potential energy, pushing the triangular block 26 back to its original position. When the connecting rod 10 is installed into the square rod 9 next time, the clamping plate 24 will press the inclined surface of the triangular block 26, and the triangular block 26 will deform under force. When the triangular block 26 and the slot 25 are on the same plane, the pressure of the clamping plate 24 on the triangular block 26 ends, and spring 30 releases its elastic potential energy. The triangular block 26 will then return to its original position inside the slot 25, thus realizing the function of quick installation of the connecting rod 10 and the square rod 9.

[0056] The above-described embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
