Description

Technical Field

[0001] This application relates to the field of PCB manufacturing equipment technology, and more specifically, to a lamination and hot melt integrated machine. Background Technology

[0002] In the manufacturing process of PCB (printed circuit board), there is a process called pre-stacking. Its purpose is to align each core board and PP (prepreg) of the multilayer board and then fix them in place by heat fusion. This way, there will be no misalignment problem during lamination.

[0003] Because PCBs consist of multiple layers, the stacking of core boards and PP sheets is repeatedly required during production to obtain the desired PCPCP structure (where P stands for PP and C for core board). Currently, the method used is to separate PP sheets and core boards of different stacking positions and specifications before stacking, and employees take them out in sequence to avoid problems such as overstacking, understacking, or misplacement. This operation method heavily relies on the work skills and attitude of employees to avoid PP sheet or core board stacking errors, and cannot completely prevent abnormal situations. In actual production, problems of misplacement or understacking have occurred many times. To prevent defective PCB products from entering the market due to stacking errors, an additional person is needed to count the number of PP sheets stacked on each board to ensure that the quantity and position of PP sheets are correct. However, this method is inefficient, slow, and has high labor costs, making it difficult to meet production needs. Summary of the Invention

It should be noted that the following embodiments can be referenced, borrowed from, or combined with each other. Identical terms, similar features, and similar implementation steps in different embodiments will not be repeated.

[0067] The lamination and hot-melt integrated machine provided in this application is intended to solve at least one technical problem existing in the prior art.

[0068] Optionally, such as Figures 1-21 As shown, the integrated lamination and hot-melt machine of this application includes: a feeding module for combining PP and core board 5 to form a CPC pre-stacked structure; a transfer module 2 for transferring the CPC pre-stacked structure and CPC units; a hot-melt module 3 for hot-melting the CPC pre-stacked structure transferred by the transfer module 2 to form CPC units to be transferred by the transfer module 2; and a unloading module for stacking PP on the CPC units transferred by the transfer module 2 to form a PCPCP structure for unloading. This integrated machine achieves integrated hot-melt lamination of boards, eliminates manual loading and unloading errors through process fusion, and improves overall process stability.

[0069] Optionally, the feeding module includes a first feeding platform 11, a second feeding platform 14, a combination platform 16, and a transfer unit. The first feeding platform 11, the second feeding platform 14, and the combination platform 16 are located on both sides of the transfer unit. The first feeding platform 11 is used to place the core board 5, and the second feeding platform 14 is used to place the PP. The transfer unit is used to transfer the core board 5 from the first feeding platform 11 and the PP from the second feeding platform 14 to the combination platform 16 to form a CPC pre-stacked structure. The transfer unit can sequentially move the core board 5 from the first feeding platform 11 and the second feeding platform 14 to the combination platform 16 according to the stacking sequence to achieve the initial stacking of the core board 5 and the PP.

[0070] Optionally, the core plates 5 on both sides of the PP in the CPC structure can be the same or different. Specifically, there can be two first loading platforms 11, with the core plates 5 they support positioned differently within the CPC structure. When forming the CPC structure, the core plate 5 serving as the bottom of the CPC structure can be removed from one of the first loading platforms 11, and the core plate 5 serving as the top of the CPC structure can be removed from the other first loading platform 11. The two first loading platforms 11 can be located on the same side of the transfer unit and along the movement path of the transfer unit.

[0071] Optionally, the second loading platform 14 and the combination platform 16 can be located on the same side of the transfer unit, while the first loading platform 11 is located on the other side of the transfer unit.

[0072] Optionally, a first limiting member 111 may be provided around the top of the first loading platform 11. The position of the first limiting member 111 can be determined according to the size and shape of the core board 5, and the first limiting member 111 is used to confine the core board 5 within a fixed area. The core boards 5 on the first loading platform 11 can be placed manually by stacking them. When placing the core boards 5, the first limiting member 111 is used to ensure that the core boards 5 can be located within the fixed area.

[0073] Optionally, the first loading platform 11 may include a first table surface 113, and the first limiting member 111 and the core plate 5 may be disposed on the top of the first table surface 113.

[0074] Optionally, a first fixing structure and a first base 112 may be provided at the bottom of the first tabletop 113. The first fixing structure may include a second slide rail 116, a first slide block 114, a third slide rail 117, and a second slide block 115. The second slide rail 116 and the second slide block 115 are fixed to the bottom of the first tabletop 113, with the second slide block 115 located at the end of the second slide rail 116 and spaced apart. The third slide rail 117 and the first slide block 114 are fixed to the first base 112, with the first slide block 114 located at the end of the third slide rail 117 and spaced apart. The first slide block 114 and the second slide block 115 are located on different sides of the first tabletop 113, and the second slide rail 116 is opposite to the third slide rail 117. The top of the first slide block 114 is slidably embedded in the second slide rail 116, and the bottom of the second slide block 115 is slidably embedded in the third slide rail 117. This structure, which allows for slight adjustment of the position of the first tabletop 113, fixes the first tabletop 113 to the first base 112.

[0075] In one embodiment, the number of the second slide rail 116 and the third slide rail 117 can both be two. The two second slide rails 116 at the bottom of the first table 113 are arranged in parallel, and the second slide rails 116 are perpendicular to the direction of the transfer unit to transfer the core plate 5.

[0076] Optionally, in order to detect whether the transfer unit is transferring the core board 5 from the first loading table 11 or whether the core board 5 is manually placed on the first loading table 11, or other actions performed on the first loading table 11, a first detection component 118 may also be provided around the first table surface 113. The first detection component 118 may include a laser emitting device, a reflecting device, and a detection device. These devices may be set at the four corners of the first table surface 113, and determine whether the first table surface 113 is currently in an operation execution state (such as the transfer unit removing the core board 5 or the core board 5 being manually placed) by detecting whether the emitted or reflected laser is blocked.

[0077] Optionally, the structure of the first loading platform 11 can be the same as that of the second loading platform 14, both of which are provided with a first limiting member 111, a first table surface 113 and a first fixing structure.

[0078] Optionally, to further secure the PP, the second loading platform 14 may also be provided with a second limiting member 141 in addition to the first limiting member 111. The second limiting member 141 may include a limiting cylinder 1411 and a limiting seat 1412. A limiting opening 142 is provided at a position corresponding to the second limiting member 141 on the first platform 113. The second limiting members 141 are located on both sides of the first platform 113. When it is necessary to secure the PP, the limiting cylinder 1411 pushes the limiting seat 1412 into the limiting opening 142 and abuts against the side of the PP to secure it. The limiting seat 1412 may also have multiple protrusions on the side near the PP. These protrusions can form an arranged toothed structure, which further enhances the securing effect.

[0079] Optionally, the platform of the assembly table 16 may be provided with multiple air holes, which are located within the placement area of ​​the CPC structure. The assembly table 16 has a gas transmission pipe communicating with the air holes inside. The CPC structure is placed on the assembly table 16 via vacuum adsorption through this structure. The assembly table 16 may be located on the side of the second loading platform 14 near the hot melt module 3.

[0080] Optionally, multiple limiting protrusions 161 may be provided around the placement area to restrict the movement of the CPC structure. These limiting protrusions 161 protrude from the surface of the assembly table 16. When the CPC structure moves, the limiting protrusions 161 abut against the sides of the CPC structure. Vacuum adsorption on the table surface and the limiting protrusions 161 prevent the materials (core board 5 and PP) from shifting during the stacking process.

[0081] In one embodiment, in order to facilitate the transfer module 2 to clamp the CPC structure on the assembly table 16, multiple clamping slots corresponding to the transfer module 2 can be provided on both sides of the CPC structure placement area. When the transfer module 2 needs to clamp the CPC structure, the part of the transfer module 2 used to clamp the CPC structure extends into the clamping slot to contact the bottom side of the CPC structure, thereby realizing the clamping of the CPC structure.

[0082] Optionally, the feeding module further includes a first calibration platform 12 and a second calibration platform 15. The first feeding platform 11 and the first calibration platform 12 are located on the same side of the transfer unit, while the second calibration platform 15, the second feeding platform 14, and the combination platform 16 are located on the other side of the transfer unit. The first calibration platform 12 is used to calibrate the core board 5 transferred by the transfer unit so that the core board 5 transferred to the combination platform 16 is the calibrated core board 5. The second calibration platform 15 is used to calibrate the PP transferred by the transfer unit so that the PP transferred to the combination platform 16 is the calibrated PP. The first calibration platform 12 is located on the side of the first feeding platform 11 closer to the hot melt module 3, and the second feeding platform 14, the second calibration platform 15, and the combination platform 16 are arranged sequentially from farthest from the hot melt module 3.

[0083] Optionally, the first calibration table 12 may have multiple air holes on its surface. During calibration, the air holes are used to adsorb the core plate 5 to fix the core plate 5.

[0084] Optionally, the first calibration stage 12 may further include a detection frame 121 and a first calibration component 122. The bottom of the detection frame 121 may be fixed to one side of the table surface of the first calibration stage 12, and the top of the detection frame 121 extends above the table surface. The first calibration component 122 is disposed on the detection frame 121 and opposite to the table surface. The first calibration component 122 acquires images of the core board 5 on the table surface and calibrates the core board 5 based on the images, thereby achieving CCD visual calibration. The first calibration component 122 may include a CCD camera. The images captured by the camera determine the position of the core board 5 so that the transfer unit can transfer the core board 5 in the correct manner (e.g., adsorbing the core board 5 to a specific position so that the core board 5 can be correctly stacked with the PP).

[0085] Optionally, the second calibration table 15 may also be provided with air holes on its surface. These air holes are located around the PP placement area on the table, and the PP placed in the PP placement area by the vacuum adsorption unit is used to prevent it from moving.

[0086] Optionally, the second calibration table 15 can calibrate the PP placed on it using a mechanical calibrator. The second calibration table 15 may include a mechanical calibrator structure equipped with a pusher cylinder 152 and a pusher component 151. This mechanical calibrator structure can be arranged around the PP placement area to achieve PP position calibration.

[0087] In one embodiment, a pusher cylinder 152 is fixed below the table surface of the second calibration table 15, and the drive end of the pusher cylinder 152 is connected to the pusher component 151. A pusher groove 153 is provided on the table surface, and the top of the pusher component 151 extends into the pusher groove 153. The pusher cylinder 152 pushes the pusher component 151 to move within the pusher groove 153. The pusher groove 153 is located on the side of the PP fixing area. During calibration, the pusher cylinder 152 drives the pusher component 151 close to the PP placement area and contacts the side of the PP to push it into the PP placement area, allowing the PP to be positioned at a predetermined position within the PP placement area, thus achieving the calibration of the PP.

[0088] Optionally, a second detection component 154 may be provided on the table surface of the second calibration table 15. The second detection component 154 may be set at the four corners of the table surface and detect whether there is a PP placed on the second calibration table 15 or whether it is necessary to remove the PP on the second calibration table 15. Then, the mechanical clapper structure is controlled to move (such as calibrating or releasing the PP) according to the detection result.

[0089] Optionally, the transfer unit includes a first transfer machine and a second transfer machine 17, which are located between the first loading platform 11 and the second loading platform 14. The first transfer machine is used to transfer the core board 5 to the first calibration platform 12 and to transfer the calibrated core board 5 to the assembly platform 16. The second transfer machine 17 is used to move the PP to the second calibration platform 15 and to move the calibrated PP to the assembly platform 16.

[0090] Optionally, the second calibration table 15 and the combination table 16 are located on the same side of the second transfer machine 17; the first transfer machine includes a first sub-transfer machine 131 and a second sub-transfer machine 132. The transfer direction of the first sub-transfer machine 131 is the same as that of the first transfer machine, and it is used to transfer the core board 5 to the first calibration table 12; the transfer direction of the second sub-transfer machine 132 is perpendicular to that of the first sub-transfer machine 131, and it is used to transfer the calibrated core board 5 to the combination table 16.

[0091] In one embodiment, the first calibration platform 12 is arranged opposite to the combination platform 16, and the second sub-transfer machine 132 is arranged between the combination platform 16 and the hot melt module 3.

[0092] Optionally, to reduce costs, the first sub-transfer machine 131 and the second sub-transfer machine 132 can operate in the same way as the second transfer machine 17. The first transfer machine and the second transfer machine 17 can pick up the material on the loading platform (first loading platform 11 and second loading platform 14) by adsorption and transfer the material to the corresponding calibration platform. After calibration by the calibration platform, the material after calibration on the calibration platform is adsorbed and then transferred to the combination platform 16.

[0093] Optionally, both the second transfer machine 17 and the first transfer machine may include a first lifting driver (which can be a linear motor or a cylinder), an adsorption bracket, and a suction cup. The driving end of the first lifting driver is connected to the adsorption bracket, and the bottom of the adsorption bracket is equipped with a suction cup. After the second transfer machine 17 moves the adsorption bracket above the second loading platform 14 or the second calibration platform 15, the first lifting driver drives the adsorption bracket to descend, thereby causing the suction cup on the adsorption bracket to contact the PP to achieve adsorption of the PP. When it is necessary to place the PP, the first lifting driver drives the adsorption bracket to descend, thereby causing the PP adsorbed by the suction cup on the adsorption bracket to contact the platform surface. Then, the suction cup is controlled to release the PP to achieve the PP placement. The adsorption and placement method of the core board 5 is the same as the adsorption and placement method of the PP.

[0094] Optionally, the second transfer machine 17 may further include a translation driver 1314, a translation rail 1315, and a second lifting frame. The second lifting frame is movably fixed on the translation rail 1315. The translation driver 1314 is disposed on one side of the translation rail 1315 and is connected to the transfer bracket 21 via a transmission connection, thereby driving the transfer bracket 21 to move along the translation rail 1315. The first lifting driver may be fixed on one side of the lifting frame, and the suction bracket is fixed to the drive end of the first lifting driver.

[0095] In one embodiment, the translation track 1315 of the second transfer machine 17 can be arranged along the arrangement direction of the second loading platform 14, the second calibration platform 15 and the combination platform 16. The translation driver 1314 can drive the translation bracket to move according to the received instructions, so that the suction cup on the adsorption bracket can move to the platform corresponding to the instructions to achieve the adsorption or placement of PP.

[0096] Optionally, in the second transfer machine 17, the adsorption bracket may include a first support rod 1311 and a second bracket, and the number of lifting drivers may be two. Both the first support rod 1311 and the second bracket are provided with suction cups, and the lifting drivers connected to the first support rod 1311 and the second support rod 1312 are different.

[0097] Optionally, the second lifting frame may include two lifting columns 171 and a translation base. The bottom of the lifting column 171 is fixed to the translation base, and the translation base is movably fixed to the translation track 1315 and is connected to the translation driver 1314. Each lifting column 171 is provided with a first lifting driver, and the lifting columns 171 connected to the first support rod 1311 and the second support rod 1312 are different.

[0098] Optionally, the structure of the first sub-transfer machine 131 can be the same as that of the second sub-transfer machine 132.

[0117] The following section will further explain the workflow of the composite hot melt machine.

[0118] In one embodiment, the workflow of the all-in-one machine includes:

[0119] ① Loading and CPC Pre-stacking: Core boards 5 and PP are manually placed on their respective loading platforms (first loading platform 11, second loading platform 14). The lower CORE (core board 5 at the bottom of the CPC structure) is transferred to the first calibration platform 12 by the first sub-transfer machine for calibration. After calibration, the first sub-transfer machine picks up the calibrated core board 5 and transfers it to the assembly platform 16. The PP on the second loading platform 14 is transferred to the second calibration platform 15 by the second transfer machine. After mechanical calibration, it is picked up by the second transfer machine and transferred to the assembly platform 16. The upper CORE (core board 5 at the top of the CPC structure) completes calibration and transfer according to the same process, and finally the CPC structure is assembled on the assembly platform 16.

[0120] ② Hot melt: The transfer module 2 picks up the pre-stacked CPC structure from the assembly table 16 and transfers it to the hot melt machine for hot melt curing to form a preliminary PCB stacking unit, ensuring the interlayer bonding strength.

[0121] ③ Material feeding and PCPCP assembly: After hot melting, the third transfer machine on the right side picks up the PP and performs CCD correction through the third correction table 42. It then continues to pick up the PP and transfer it to the carrier platform 411 of the trolley (discharge unit 41). The transfer module clamps the CPC unit and transfers it above the PP already placed on the carrier platform 411. The third transfer machine then picks up another third-corrected PP and places it above the CPC unit, forming a PCPCP structure. The finally pre-stacked unit products are staggered at approximately 3 cm intervals and evenly arranged above the carrier platform 411 of the discharge unit 41, completing the material feeding.

[0122] The lamination and hot melt integrated machine of this application has the following advantages:

[0123] ① Fully automated process: Achieve full-chain automation of "feeding-correction-assembly-hot melting-stacked discharge".

[0124] ② Integrated hot-melt stacking: Process integration eliminates errors caused by manual loading and unloading, and improves the overall process stability.

[0125] ③ Efficiency and precision: Visual CCD correction and mechanical positioning are used to ensure accurate material alignment. Vacuum adsorption and limiting components on the table prevent material from shifting during stacking.

[0126] Breaking away from the limitations of traditional manual intervention and process fragmentation, it achieves "high precision, high efficiency, and high compatibility" in the PCB lamination process, and is especially suitable for the current PCB industry's mass production needs for thinner, multilayer boards.
