Description

Technical Field

[0001] This invention relates to the field of PCB board lamination technology, and in particular to a PCB board lamination machine. Background Technology

[0002] A PCB (Printed Circuit Board) is the support structure and electrical connection carrier for electronic components, and is an indispensable part of electronic equipment. Currently, PCBs are mainly produced using a lamination process. In the lamination process, a layer of copper foil is laid on the lower mold of the laminator, followed by the first layer of prepreg (also called PP board), the core board, and the second layer of prepreg in sequence. Finally, another layer of copper foil is placed on top to complete the layout. The upper mold then presses the arranged copper foil and core board together to form the PCB.

[0003] However, currently, the layout of prepreg and core board in the PCB lamination process is mostly done manually. Furthermore, workers need to perform dust removal on the prepreg and core board before lamination, which requires workers to have a high level of proficiency to meet the company's production capacity. Therefore, whenever front-line workers leave or are reassigned, it can take several weeks for a new employee to master and become proficient in layout, dust removal, and other tasks. Thus, improvements to the existing PCB lamination machines are necessary.

[0004] In summary, the present invention aims to provide a pressing machine that can replace workers in the layout and dust removal of prepreg and core board. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the present invention aims to provide a PCB board laminating machine that has the advantages of arranging and electrostatically removing prepreg and core board, allowing workers to focus solely on loading materials, making it extremely easy to operate.

[0006] The technical solution of the present invention is implemented as follows: a PCB board pressing machine includes a lower mold assembly, an upper mold assembly, a lifting mechanism for controlling the lifting and lowering of the upper mold assembly, and a heating module disposed in the lower mold assembly and the upper mold assembly. The pressing machine of the present invention also includes a layout dust removal device, which includes a feeding device and a layout chamber that is controlled to move and lift by the feeding device. The typesetting chamber includes a chamber body, a workstation rotatably disposed within the chamber body and having at least three workstations for fixing prepregs or core boards, and a dust removal structure; the dust removal structure has an air outlet chamber formed within the chamber body and air outlet holes distributed on the inner wall of the chamber body, and the air outlet chamber is connected to an air supply source through an air supply pipe. The bottom of the silo is provided with a discharge port, and each station can pass through the discharge port in sequence and loosen the semi-cured sheet or core board when rotating.

[0007] Preferably, the feeding device includes a moving track, a moving seat slidably connected to the moving track, and a lifting structure mounted on the moving seat; The moving track is equipped with a rack and a limiting slide rail, and a moving seat gear controlled by a first motor is rotatably connected to the moving seat. The moving seat gear meshes with the rack.

[0008] Preferably, the lifting structure includes a lifting rail, a mounting base slidably connected to the lifting rail, and a lead screw structure mounted on the movable base; the lead screw structure is arranged parallel to the lifting rail, and the lead screw bearing seat of the lead screw structure is connected to the mounting base.

[0009] Preferably, the typesetting compartment includes a compartment body, at least three workstation structures with said workstations, a support structure for supporting and driving the rotation of each workstation structure, and a dust collection structure rotatably disposed at the center of the compartment body and capable of controlling the rotation of the support structure. Among them, each workstation structure can be controlled by the support structure to retract towards the dust collection structure or disperse towards the inner wall of the silo; after the workstation structure retracts and cooperates with the dust collection structure, the workstation structure can be controlled by the dust collection structure to rotate and control each workstation to pass through the discharge port in sequence; after the workstation structure disperses, the workstation and the inner wall of the silo with the air outlet are inclined. The outer wall of the silo is provided with a feeding port, and a movable sealing plate is provided at the feeding port.

[0010] Preferably, the dust collection structure includes a dust collection shaft rotatably mounted at the center of the chamber by a second motor and a dust collection port formed on the dust collection shaft; a chuck is fixedly connected to the dust collection shaft, and one end of the dust collection shaft is connected to a dust collection source through a dust collection pipe.

[0011] Preferably, the compartment body has a disassembly port on one side, and the support structure includes: The cover plate is compatible with the disassembly port and can be detachably connected to the compartment body; The turntable is rotatably mounted on the cover plate; The motor cavity is located inside the cover plate; The turntable is rotatably connected to a plurality of first gears corresponding to the structure of each workstation and a second gear that meshes with each first gear and is driven by a third motor. The turntable is fixedly connected to a support shaft sleeved on the suction shaft. The support shaft has a support shaft opening corresponding to the suction port, and a shaft head that cooperates with the chuck is provided at one end of the support shaft.

[0012] Preferably, the shaft head has a chuck cavity for the chuck to enter, and suitable limiting ribs and limiting grooves are provided on the mating surfaces of the chuck and the chuck cavity.

[0013] Preferably, the workstation structure includes: The workstation frame is coaxially connected to the first gear via a shaft. The work station slot is recessed on the work station frame and is equipped with several vacuum suction cups; A vacuum chamber is formed on the workstation frame and is connected to a vacuum suction cup; The vacuum chamber is connected to a vacuum source via a vacuum tube.

[0014] Preferably, the workstation frame is provided with a dust discharge chamber located between adjacent workstation slots, and the outlet of the dust discharge chamber can be connected to the dust suction port after the workstation frame is retracted.

[0015] Preferably, an ion air knife is installed on the wall of the dust removal chamber, and the ion air knife and the air outlet chamber are connected to an ion air generator through an air supply pipe.

[0016] The present invention has at least the following beneficial effects: 1. The typesetting chamber of this invention can remove dust from the prepreg (hereinafter referred to as PP board) and core board after loading. During the dust removal process, the typesetting chamber moves synchronously to the lower module and completes the dust removal after moving to the lower module position. Then, the typesetting chamber puts the PP board and core board into the lower module in sequence for typesetting to complete the typesetting. In actual operation, the worker first puts a layer of copper foil into the lower module, then uses the layout chamber for layout, and finally the worker lays another layer of copper foil. During the pressing process of the upper and lower modules, the worker feeds the layout chamber to prepare for the next round of pressing.

[0017] 2. The workstation structure of the present invention can be folded up and dispersed under the control of the support structure. More specifically, the workstation structure can maintain two modes under the control of the support structure. In the folded state (or mode), the rotation of the workstation structure is used for orderly layout and dust removal of the layoutd PP boards and core boards. In the dispersed state (or mode), the rotation of the workstation structure will bring the workstation closer to the feeding port, making it easier for workers to feed materials. At the same time, it also brings workers closer to the air jet holes distributed on the inner wall of the layout chamber, making it easier to receive the ion wind ejected from the air jet holes, which helps to remove impurities from the PP boards and core boards.

[0018] 3. In the dispersed state (or mode), the present invention supplies the ion wind ejected from the jet hole to the surface of the PP board or core board at an inclined angle, which makes it easier to remove impurities from the surface of both. At the same time, in the dispersed state, the dust suction port on the dust suction shaft is exposed, and the two ends of the dust discharge chamber on the workstation frame correspond to the exhaust side and the dust suction port of the workstation. Therefore, the impurities that are separated from the PP board or core board by the ion wind can flow from the dust discharge chamber to the dust suction port on the exhaust side of the workstation and be successfully sucked away.

[0019] 4. The present invention also installs an ion air knife in the dust removal chamber of the workstation frame. The ion air knife is used to remove dust from the PP board or core board after layout. Moreover, as the workstation frame rotates as a whole, the ion air knife also rotates. The rotation allows the ion air knife to blow air onto the PP board and core board at different angles to improve the dust removal effect. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Example 1, Reference Figures 1-10 As shown: This embodiment discloses a PCB board laminating machine, including a frame 10, a lower mold assembly, an upper mold assembly, a lifting mechanism for controlling the lifting of the upper mold assembly, a heating module disposed in the lower mold assembly and the upper mold assembly, and a layout dust removal device.

[0024] First, refer to Figure 1 In this embodiment, a fixed plate 16 is fixed on the frame 10 by a support column 15. The lifting mechanism is a cylinder 13 on the fixed plate 16. A lower pressure plate 12 is installed at the output end of the cylinder 13. The lower pressure plate 12 is slidably connected to the support column 15. An upper mold positioning plate (not shown) and an upper mold assembly (not shown) are installed at the bottom of the lower pressure plate 12. The lower pressure plate, the upper mold positioning plate, and the upper mold assembly constitute the upper mold assembly of this embodiment. The heating module is a heating tube set in the upper mold assembly. The lower mold assembly is a lower mold assembly 11 installed on the frame 10. The lower mold assembly 11 has a placement cavity and is also equipped with a heating tube inside. The upper mold assembly and the lower mold assembly are mutually compatible.

[0025] In addition to the above, the frame 10 of this embodiment should also be equipped with a controller. The controller's display panel 20 is located on the outside of the frame. The frame 10 is also equipped with a start button 21 and several control buttons 22. The controller of this embodiment is used to control the lifting mechanism, the heating module and the typesetting dust removal device. By using each control button, the lifting mechanism, the heating module and the typesetting dust removal device can be used through the controller.

[0026] Of course, to ensure the use of this embodiment, the telescopic shaft (or lower pressure plate 12) of the cylinder in this embodiment is equipped with a pressure sensor connected to the controller, and the fixed plate 16 is also equipped with a sensor transmitter 16a. The pressure sensor can detect the pressure intensity of the cylinder pressing down and feed the pressure value back to the display panel through the sensor transmitter.

[0027] The above is a brief description of the basic structure of the existing pressing machine in this embodiment. Since the upper mold assembly, lower mold assembly, heating module, lifting mechanism and controller are mature existing technologies, their specific structures will not be described in detail in this embodiment.

[0028] The core technical point of this embodiment is that a typesetting dust removal device 3 (such as...) is added to the existing pressing machine. Figure 2 As shown in the figure, the typesetting dust removal device 3 in this embodiment includes a feeding device 30 and a typesetting bin 31 that is controlled by the feeding device 30 to move and rise and fall. The typesetting chamber 31 includes a chamber body 310, a workstation rotatably disposed within the chamber body 310 and having three stations for fixing prepregs or core boards, and a dust removal structure. In this embodiment, the dust removal structure has an air outlet chamber 40 formed within the chamber body 310, and air outlet holes 41 are distributed on the inner wall of the chamber body 310. The air outlet chamber is connected to an air supply source through an air supply pipe 42. In this embodiment, the air supply source is selected as an ion wind generator (such as an ion fan). The ion fan sends ion wind into the air outlet chamber through the air supply pipe and sprays it out through the air outlet holes 41. In this embodiment, the bottom of the hopper 310 is provided with a discharge port 310a. Each station can pass through the discharge port 310a in sequence and release the semi-cured sheet or core board when rotating. That is, when the station transports the semi-cured sheet or core board to above the discharge port 310a, the station temporarily stops rotating and releases the semi-cured sheet or core board so that both can be discharged from the hopper 310 through the discharge port.

[0029] refer to Figures 1-4 The feeding device 30 of this embodiment includes a moving rail 300 fixed on the frame 10, a mounting cavity 301 provided in the moving rail 300, a moving seat 303 slidably connected to the moving rail 302 via a slider 302, and a lifting structure installed on the moving seat 303. The moving track 300 (installation cavity 301) is provided with a rack 304 and a limiting slide rail 305. There are two limiting slide rails 305 arranged in parallel within the moving track 300. The slider 302 is slidably connected to the limiting slide rail 305, and the moving seat is installed on the slider 302. In this embodiment, there is a height difference between the rack 304 and the limiting slide rail 305, which can prevent the rack from affecting the sliding of the slider 302. In this embodiment, a moving seat gear 307 controlled by a first motor 306 is rotatably connected to the moving seat 303. The moving seat gear 307 meshes with a rack 304. The first motor 306 is mounted on the moving seat. Thus, when the first motor drives the moving seat gear 307 to rotate clockwise or counterclockwise, the moving seat can be controlled to move forward or backward by means of the engagement between the moving seat gear and the rack (it should be defined that moving forward means moving towards the lower module, and vice versa).

[0030] The lifting structure of this embodiment includes a lifting rail 308 mounted on a movable seat, a mounting seat 309 slidably connected to the lifting rail 308, and a lead screw structure mounted on the movable seat 309. The lead screw structure is arranged parallel to the lifting rail 308, and the lead screw bearing seat of the lead screw structure is connected to the mounting seat 309. More specifically, the lead screw structure includes a lead screw motor 309a and a lead screw 309b rotatably connected to the movable seat and controlled by the lead screw motor 309a. A lead screw bearing seat 309c is adapted to be connected to the lead screw 309b, and the lead screw bearing seat 309c is connected to the mounting seat 309. The mounting seat 309 is controlled by the lead screw structure to perform lifting and lowering movements.

[0031] refer to Figures 2-3 as well as Figures 6-9 The typesetting chamber 31 in this embodiment includes a chamber body 310, a workstation structure with three workstations, a support structure for supporting the workstation structure, and a dust collection structure rotatably located at the center of the chamber body and capable of controlling the rotation of the support structure. The outer wall of the chamber body 310 is provided with a loading port 310b, and a movable closing plate 310c is provided at the loading port 310b. The closing plate 310c has a protrusion 310d for easy movement, and a magnet 310e is hidden inside the protrusion 310d. A magnetic block 310f (a metal block that can be attracted by a magnet) is provided inside the edge of the loading port 310b. When the closing is moved, the closing plate is fixed to the top or bottom by the attraction between the magnet and the magnetic block (e.g., ...). Figure 6 and Figure 7 (State), and the hopper 310 is provided with an opening that communicates with the feed port 310b. When the closing plate moves, it can move through the opening. To ensure smooth movement of the closing plate 310c, the inner wall of the feed port 310b is provided with a limiting groove 310g. The two sides of the closing plate 310c slide within the limiting groove 310g, and a limiting slot 310h is provided on the lower inner wall of the feed port 310b. When the closing plate is closed, the bottom of the closing plate is inserted into the limiting slot 310h. The top of the limiting groove 310g is through-hole, and the bottom of the limiting groove communicates with the limiting slot.

[0032] In this embodiment, the mounting base 309 is provided with a seat opening 309a larger than the discharge port, and the hopper body is detachably connected to the mounting base 309 by bolts.

[0033] The vacuuming structure of this embodiment includes a vacuuming shaft 51 rotatably disposed at the center of the chamber 310 by the second motor 50 and a vacuuming port 52 formed on the vacuuming shaft 51; a chuck 53 is fixedly connected to the vacuuming shaft 51, and one end of the vacuuming shaft 51 is connected to a vacuuming source (an existing vacuum cleaner) through a vacuuming pipe 54.

[0034] In this embodiment, the compartment is divided into a first compartment 61 and a second compartment 62 by a partition 63. The top of the compartment is provided with a heat dissipation vent communicating with the first compartment 61. The partition 63 is provided with a communication port, and the inner wall of the communication port is provided with an annular groove 63a. A rotating disk 63b is provided at the communication port, and the edge of the rotating disk 63b is provided with an annular track 63c that moves within the annular groove 63a, so that the rotating disk can rotate on the partition. In this embodiment, the second motor is installed in the first compartment 61. The opening of the first compartment 61 is detachably connected to the first compartment plate 61a by bolts, and the center of the first compartment plate 61a is provided with a compartment plate opening 61b.

[0035] In this embodiment, the suction shaft 51 is coaxially fixed with the rotating disk, and a first pulley 64 is connected to the suction shaft. A second motor drives a second pulley 65. A belt is connected between the first pulley and the second pulley. The second motor controls the rotation of the rotating disk and the suction shaft through the pulley assembly.

[0036] In this embodiment, the opening of the second compartment 62 is detachably connected to a second compartment plate 62a via bolts. The second compartment plate 62 serves as the support structure in this embodiment, and a rotatable support plate 620 is provided on the second compartment plate 62. The workstation structure in this embodiment includes a fixing frame 68 fixed to the support plate 620 and a fixing shaft 69 with one end fixedly connected to the support plate 620. The fixing frame 68 has a regular hexagonal cross-section, and three spaced surfaces of the fixing frame 68 are provided with workstation slots 68a (workstations in this embodiment). The width of the work station slot for placing the core board is smaller than the width of the work station slot for placing the PP board. The width and length of the work station slot are adapted to the corresponding core board and PP board, respectively. The work station slot forms the work station in this embodiment. A vacuum chamber 68b is provided in the fixed frame. Several vacuum suction cups 680b connected to the vacuum chamber are provided in the work station slot. A vacuum tube 68c connected to the vacuum chamber 68b is provided on the fixed frame. In order to facilitate the adsorption of each work station slot, a vacuum valve is also provided on each vacuum tube. A control button for controlling each vacuum valve is provided on the frame.

[0037] The frame of this embodiment is also equipped with a control button for controlling the second motor. Each time the control button is pressed, the second motor rotates 60 degrees.

[0038] The fixed frame 68 in this embodiment is also provided with a dust collection chamber 68d located between adjacent workstation slots. One end of the fixed shaft 69 is provided with a shaft head 69a that is adapted to the chuck 53. The shaft head has a chuck cavity for the chuck 53 to enter, and a matching limiting rib 53a and a limiting groove are provided on the mating surface of the chuck 53 and the chuck cavity (when the chuck and the chuck cavity are mated, the support plate can be driven to rotate through the chuck and the fixed shaft). The fixed shaft 69 is provided with a shaft side opening 69b corresponding to the dust collection port 52a, and the shaft side opening is connected to the dust collection chamber 68d.

[0039] refer to Figures 7-8 as well as Figure 10 In this embodiment, the partition and the side wall of the suction shaft are respectively provided with three through holes 630b for each vacuum tube to pass through. The suction shaft head 510a of the suction shaft 51 in this embodiment is also provided with three through holes 630b. The suction shaft head 510a is connected to the suction tube 54. The fixing frame in this embodiment is provided with three vacuum tubes. Each vacuum tube passes through the through hole on the partition, the through hole on the suction shaft and the through hole on the suction shaft head, and passes out of the chamber body from the chamber plate opening 61b of the first chamber plate and connects to the vacuum generating device. A sealing ring 630c is provided at each through hole position.

[0040] refer to Figures 7-9 In this embodiment, during assembly of the support structure, workstation structure, and chamber, the fixed shaft and the dust suction shaft are aligned (the shaft side opening 69b of the fixed shaft is aligned with the dust suction port 52 on the dust suction shaft, and a sealing ring is provided on the inner wall of the fixed shaft). Then, the fixing frame is pushed into the second chamber until the shaft head of the fixed shaft engages with the chuck. Then, bolts are tightened to fix the second chamber plate, and then the layout chamber is fixed on the mounting frame.

[0041] refer to Figures 1-10 During production, the worker opens the sealing plate, then controls the second motor to drive the fixing frame to rotate via the control button, and places two PP boards and a core board into the respective work station slots. Then, the worker controls the vacuum valve to fix the core board and PP board. After the loading is completed, the worker controls the fixing frame to rotate so that the work station slot with the PP board is at the bottom, and then closes the sealing plate to complete the loading action.

[0042] After the material is loaded, the worker lays a layer of copper foil in the lower module and then presses the start button. After the start button is pressed once, the controller controls each mechanism in this embodiment to work according to the following instructions: S1: The first motor controls the rotation of the moving seat gear, thereby driving the typesetting compartment forward until it is above the lower module and then stops moving forward; S2: During the forward movement of the typesetting chamber, the ion air generator and the vacuum cleaner are activated. The ion air generator sends ion air into the air outlet chamber and sprays it out from the air outlet. The vacuum cleaner then sucks up the dust through the suction port and suction chamber. At the same time, the second motor controls the fixed frame to rotate one revolution. While rotating, the ion air blows towards the PP board and core board for electrostatic dust removal. The impurities are then sucked away through the suction chamber to complete the dust removal. After the dust removal is completed, the second motor, the ion air generator and the vacuum cleaner stop. S3: The screw motor controls the layout bin to descend and bring the discharge port closer to the lower module until the lower module is inside the discharge port and the mounting base abuts against the table below the lower module; S4: Subsequently, each vacuum valve opens in sequence, and the second motor controls the rotation of the fixing frame to place the PP board, core board and another PP board into the lower module in sequence. After completion, the lead screw motor controls the typesetting chamber to rise, and then the first motor controls the typesetting chamber to retreat to its original position.

[0043] In instruction S4, the first vacuum valve opens, then the PP board is placed into the lower module. The second motor then controls the rotating frame to rotate until the core board is positioned below. The frame stops, then the second vacuum valve opens, and the core board is placed into the lower mold base. Similarly, the last PP board is placed into the lower module. After the typesetting chamber retracts, the worker lays the final layer of copper foil and then controls the upper module to descend for pressing. During the pressing process, the worker returns to the typesetting chamber to reload.

[0044] Example 2 differs from Example 1 in that the workstation structure in Example 2 is no longer composed of a fixed frame fixed to the support plate, as follows: refer to Figures 11-17 In this embodiment, the support structure is rotatably connected to three workstation structures with workstations; each workstation structure can be controlled by the support structure to retract toward the dust collection structure or disperse toward the inner wall of the silo; after the workstation structure retracts and cooperates with the dust collection structure, the workstation structure can be controlled by the dust collection structure to rotate and control each workstation to pass through the discharge port in sequence; after the workstation structure disperses, the workstation and the inner wall of the silo with the air vent are inclined.

[0045] The compartment 310 in this embodiment has a disassembly port on one side (equivalent to the cavity opening of the second compartment in embodiment 1), and the support structure in this embodiment includes: The cover plate 70 (equivalent to the second compartment plate in Embodiment 1) is adapted to the disassembly port and detachably connected to the compartment body 310 by bolts; Turntable 71 is rotatably mounted on cover plate 70; The motor cavity 72 is located inside the cover plate 70, and the cover plate is provided with heat dissipation holes that communicate with the motor cavity; Among them, the turntable 71 is rotatably connected to three first gears 73 corresponding to the structure of each work station, and second gears 75 meshing with each first gear 73 and driven by a third motor 74; A support shaft 80 is fixedly connected to the center of the turntable 71 and sleeved on the suction shaft 51. The support shaft 80 is provided with a support shaft opening 81 corresponding to the suction port 52 (equivalent to the shaft side opening in embodiment 1), and a shaft head that cooperates with the chuck 53 is provided at one end of the support shaft 80. The shaft head of the support shaft and the mating surface of the chuck are also provided with a limiting groove and a limiting rib.

[0046] The workstation structure in this embodiment includes: The workstation frame 90 is coaxially connected to the first gear 73 via shaft 91; The workstation slot 68a (the workstation in this embodiment) is recessed on the workstation frame 90 and is provided with several vacuum suction cups 680b; Vacuum cavity 68b is formed on workstation 90 and is connected to vacuum suction cup 680b; The vacuum chamber 68b is connected to a vacuum source (vacuum generating device) via a vacuum tube 68c. The layout of the vacuum tube in this embodiment is the same as that in embodiment 1. The only difference is that after the vacuum tube is laid out, sufficient length needs to be reserved in the second chamber to ensure that the workstation frame can move.

[0047] In this embodiment, the workstation frame 90 is provided with a dust discharge chamber 92 located between adjacent workstation slots. The outlet of the dust discharge chamber 92 can be connected to the dust suction port 52 through the support shaft opening 81 after the workstation frame 90 is retracted.

[0048] In this embodiment, an ion air knife 93 is installed on the wall of the dust removal chamber 92. The ion air knife 93 and the air outlet chamber 40 are connected to an ion air generator (such as an ion fan) through an air supply pipe. In this embodiment, due to the addition of the ion air knife, three additional through holes need to be set in the partition, the suction shaft, and the suction shaft head. These through holes are used for the air supply pipe of the ion air knife to be laid out and uniformly pass out from the opening of the first compartment plate. In order to avoid affecting the dust collection, the vacuum tube and the air supply pipe of the ion air knife are arranged close to the inner wall of the suction shaft when they are laid out in the suction shaft, so as to avoid these pipes affecting the connection between the suction shaft and the suction pipe.

[0049] It should be noted that, for better control, a two-position five-way valve can be used to configure the air supply pipes of the ion air knife and the air supply pipes of the air outlet chamber. The inlet (P port) of the two-position five-way valve is connected to the ion blower, and the other four outlets are respectively connected to the air supply pipes of the three ion air knives and the air supply pipes of the air outlet chamber. That is to say, the three ion air knives can be controlled to spray air individually, while the air outlet chamber in this embodiment sprays air into the second chamber simultaneously.

[0050] In this embodiment, the turntable 71 has an annular slide rail on its edge, and an annular groove for the annular slide rail to move on the inner wall of the motor cavity of the cover plate. That is, the cooperation method between the turntable and the cover plate is the same as the installation method between the partition and the chamber. In addition, a motor plate 71b is fixed on the turntable by a support column 71a, and a third motor is fixed on the motor plate. The support column is located between adjacent first gears and does not affect the cooperation between the first gear and the second gear. The turntable also has a limiting column 71c, and a limiting arc groove 71d is provided on the second gear 75. The limiting column moves in the limiting arc groove, and the limiting arc groove determines the rotation stroke of the second gear. When the workstation frame is closed (refer to...), the rotation path is determined by the limiting arc groove. Figure 14 The limiting post is located at one end of the limiting arc groove. When the workstation frame is dispersed and unfolded (refer to...), Figures 15-17 The limiting post is positioned before the other end of the limiting arc groove, thus preventing the workstation frame from over-expanding and touching the inner wall of the second compartment.

[0051] In this embodiment, both the outer walls of the support shaft and the outer walls of the suction shaft are fitted with sealing rings to improve the sealing between the workstation frame and the support shaft, as well as between the support shaft and the suction shaft.

[0052] refer to Figures 11-17 The advantages of this embodiment are: In this embodiment, the three workstation racks can be dispersed and retracted. The retracted state is used for unloading and when using the ion air knife, while the dispersed state is used for loading and dust removal of the core board and PP board via the air vents. Specifically: 1. In distributed mode (refer to) Figure 17 The workstation slots on the workstation rack are closer to the loading port, making it easier for workers to load materials; 2. In distributed mode (refer to) Figure 16 The work station slot is closer to the wall of the second chamber, which makes the core plate and PP plate closer to the air outlet, resulting in better dust removal. In addition, in the dispersion mode, when the work station slot passes through the air outlet's jet direction, the jet direction of the air outlet will be at an inclined angle to the core plate and PP plate, making it easier to carry away impurities.

[0053] In this embodiment, after the PP board or core board is placed into the lower module, the station frame is rotated so that the dust removal chamber aligns with the PP board or core board on the lower module. At this time, the ion air knife sprays air onto the PP board and core board in the lower module, and then the dust is sucked away by the dust removal chamber. In other words, after the material is loaded, the PP board and core board are dusted on one side in the layout chamber. After the PP board and core board are placed into the lower module, the other side of the PP board or core board is dusted using the ion air knife and the dust removal chamber.

[0054] During lamination, a layer of copper foil is first laid inside the lower mold. Workers then place the core board and PP board into the slots of each workstation through the loading port (see reference). Figure 17 After the material loading is completed, the work station slot containing the PP board is positioned at the bottom (see reference). Figure 14 Then press the start button, and the controller will operate the typesetting dust removal device according to the following instructions: Z1: The first motor controls the rotation of the moving seat gear, thereby driving the typesetting chamber forward until the typesetting chamber is above the lower module and then stops moving forward; Z2: During the forward movement of the typesetting chamber, the ion air generator and vacuum cleaner are activated. The ion air generator sends ion air into the air outlet chamber and sprays it out from the air outlet, while the vacuum cleaner sucks up dust through the suction port. At the same time, the third motor controls the dispersion of each workstation rack (see reference). Figure 15 Then, the second motor controls the support port to rotate one revolution via the suction shaft, and each workstation frame rotates one revolution accordingly. Simultaneously, ion air is blown onto the PP board and core board for electrostatic dust removal (see reference). Figure 16 Then, the impurities are sucked away through the suction port to complete the dust removal. After the dust removal is completed, the second motor, the ion wind generator and the vacuum cleaner stop, and the third motor drives the workstation frame to retract. Z3: The screw motor controls the layout bin to descend and bring the discharge port closer to the lower module until the lower module is inside the discharge port and the mounting base abuts against the table below the lower module; Z4: Subsequently, each vacuum valve opens in sequence, and the second motor controls the rotation of the support shaft to place the PP board, core board and another PP board into the lower module in sequence. After completion, the lead screw motor controls the typesetting chamber to rise, and then the first motor controls the typesetting chamber to retreat to its original position.

[0055] In instruction Z4, after the first PP board is placed in, the support shaft rotates, causing the first dust removal chamber to gradually rotate to the bottom. Then, the ion air knife in the dust removal chamber blows air to remove dust from the first PP board. Then, the dust is sucked through the dust removal chamber. After that, the support shaft continues to rotate and places the core board in. Then, the second dust removal chamber rotates to the bottom and removes dust from the core board. Finally, the support shaft continues to rotate and places the second PP board in. The third dust removal chamber rotates to the bottom and removes dust from the second PP board.

[0056] After the lower module layout is completed, the workers place the second layer of copper foil and then press it together.

[0057] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
