Description

Technical Field

[0001] This invention relates to the field of PCB board lamination technology, and in particular to a high-efficiency PCB board lamination device for production lines. Background Technology

[0002] PCBs are made of polyimide or polyester film as the substrate and are characterized by high wiring density, light weight, thinness, and good flexibility. PCBs enable circuit miniaturization and visualization, playing an important role in the mass production of fixed circuits and the optimization of electrical appliance layout.

[0003] The PCB manufacturing process comprises three stages: design, manufacturing, and assembly. The design stage utilizes techniques such as layered layout and interactive routing, using software to generate schematics and PCB files. The manufacturing stage involves processes such as copper-clad laminate etching (commonly using ferric chloride etching), multilayer board lamination, and laser drilling. High-frequency circuit boards use ceramic substrates to improve thermal conductivity. The assembly stage requires balancing wiring complexity and cost. Single / double-sided boards utilize plated through-holes for optimized connections, while miniaturization relies on high-density wiring and electromagnetic shielding technology.

[0004] Multilayer board lamination is one of the important steps in PCB manufacturing. After the inner layer circuitry of the PCB is completed, the inner core board, PP (prepreg material) and outer copper foil are stacked in the design order through a special positioning method. They are then heated and laminated according to the procedures and conditions specified in the process to form a complete multilayer board structure. Finally, a laminating machine is used to laminate the multilayer PCB board.

[0005] The current PCB multilayer board pressing process is mainly achieved by a system of multiple devices working in coordination. However, with the increasing demand for automated production, the high frequency and continuous nature of production, coupled with wear and tear from frequent use of mechanical structures and system malfunctions, can affect the reliability of the coordination between equipment systems. This can easily lead to PCB multilayer boards failing to meet the actual product production requirements after pressing. Furthermore, the PCB board pressing device (publication number CN114567977B) utilizes an upper pressing mechanism, upper mold assembly, lower mold group, layout mechanism, and control device to achieve automatic loading, unloading, and pressing without manual operation. While the control device ensures the automation level of the PCB pressing device, its reliance on the coordination of the control system also reflects the aforementioned problems. Therefore, how to provide a high-efficiency PCB board pressing device for production lines is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0006] One objective of this invention is to provide a high-efficiency PCB board lamination device for production lines, in order to solve the problem that existing PCB multilayer board lamination devices, under the increasingly strong demand for automated production, are limited by the high frequency and continuous nature of production work, the wear and tear caused by frequent use of mechanical structures, and the possible failures that may occur during system use, which affect the reliability of the mutual coordination between equipment systems and easily lead to the problem that the PCB multilayer boards cannot meet the actual product production requirements after lamination.

The fifth guide rod is slidably connected to the interior of the first seat plate, and the fixed plate is assembled to the bottom of the crossbeam.

[0011] Preferably, a hook block is assembled between the two hook strips, and an isosceles trapezoidal groove is provided on the top of the suspension plate frame. Positioning slots are provided on both inner walls of the isosceles trapezoidal groove and are located inside the suspension plate frame. The cross-sections of the positioning slots and the hook block are both right-angled trapezoids, and the hook block is adapted to be connected inside the positioning slot.

[0012] Preferably, two positioning sliders are provided on the inner sidewall of the long side of the cross frame, and the top of both ends of the suspension plate frame are integrally formed with a second guide rod; the two second guide rods are respectively slidably connected inside the two positioning sliders arranged opposite each other.

[0013] Preferably, the top of the support base has a movable slot, and two support rollers are arranged on the inner side of the support base. The same roller support frame is arranged on the outer side of both ends of the two support rollers. Two first limiting grooves are opened in the inner side of both ends of the support base. A motor is assembled and connected to one end of one of the support rollers. Two slides are assembled and connected to the side of the motor near the support base. A positioning slider is integrally formed on the surface of the slide away from the motor. Two second limiting grooves are opened in the inner side of one corner of the support base. The two ends of the support roller pass through the inner side of the two roller support frames and extend into the inner side of the two opposing first limiting grooves. The two positioning sliders are slidably connected to the inner side of the two second limiting grooves. One side of the two positioning sliders is assembled and fixed to the roller support frame.

[0014] Preferably, the bottom inner wall surfaces at both ends of the bearing base are integrally formed with support strips, and two fourth guide rods are provided inside the center of each of the two roller bearing frames. A third spring is sleeved on the outside of each of the two fourth guide rods. The bottom of the fourth guide rod is threaded to the inside of the support strip, and the third spring is supported between the roller bearing frame and the support strip.

[0015] Preferably, a pressure sleeve is integrally formed on the bottom surface of the pressure plate on the side away from the center of the bearing base. An upright arm is assembled to the outside of the pressure sleeve. A second guide rod is integrally formed at the bottom of the upright arm. A third guide rod and the pressure sleeve are sleeved on the outside of the second guide rod. The third guide rod is supported between the upright arm and the pressure sleeve. The second guide rod is movably connected to the inside of the roller bearing frame and the support strip. The pressure sleeve is movably connected to the inside of the guide side plate and the bearing base.

[0016] Preferably, the two carrying rollers protrude upwards inside the movable slot, guiding the load frame to move from the roller conveyor to the top of the two carrying rollers, and the motor is located in the direction of the load frame moving to the top of the two carrying rollers.

[0017] The beneficial effects of this invention are: I. This invention uses a pressing cylinder to control the assembly base to move the pressing plate to the bottom. The synchronous pressing frame applies pressure to the top of the pressing plate, which in turn applies pressure to the protrusion on the drive rack via a second spring. When the drive rack drives the two driving gears to rotate, the driven gear drives the limiting clamping arm to rotate slightly. Finally, the end of the limiting clamping arm away from the suspension frame abuts against the positioning side frame, clamping and fixing the positioning side frame. As the pressing cylinder continuously controls the assembly base and pressing plate to move the pressing panel to the bottom, the second spring is compressed. This allows the pressing plate to continue moving to the bottom via the pressing panel while the positioning side frame is held in place by the two limiting clamping arms, thus supporting the PCB board pressing work. Furthermore, because there are fewer systems involved in the collaborative work, fewer moving parts in the positioning of the carrier, and a smaller range of motion, and the carrier is continuously moved by the roller conveyor, it is beneficial for efficient PCB board pressing. 2. The present invention pushes the suspension plate frame to the top, so that the suspension plate frame applies pressure to the inclined surface of the two hook blocks at the top. The hook blocks use the hook bar to drive the first seat plate to compress the fourth spring. With the help of the fourth spring, the hook blocks reach the positioning slot and are adapted to the inside of the positioning slot, which restricts the suspension plate frame and the locking component from disengaging. This can provide convenience for the assembly and disassembly of the cooperative positioning component at the bottom of the cross frame. Third, in this invention, the upright arm assembled to the bottom of the pressure plate applies pressure to the pressure sleeve via a third guide rod. During the process of the pressing cylinder controlling the assembly base, pressing seat plate, and pressing panel to move to the bottom, the third guide rod first transmits pressure to make the pressure sleeve push the roller support frame to move to the bottom, compressing the two third springs, so that the roller support frame carries the two support rollers to move to the bottom and retracts into the inner side of the support base, so that the top of the support rollers does not contact the bottom of the carrier. Then the third guide rod is compressed between the pressure sleeve and the upright arm, without affecting the pressing cylinder to perform the PCB board pressing work through the assembly base, pressing seat plate, and pressing panel.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0021] Example 1: The technical solution in this application embodiment addresses the problem that, with the increasing demand for automated production, the PCB multilayer board laminating device is limited by the high frequency and continuous nature of production work. This, coupled with wear and tear from frequent use of the mechanical structure and potential system malfunctions, affects the reliability of the inter-system coordination, leading to issues where the laminated PCB multilayer boards fail to meet actual product production requirements. The overall approach is as follows: To address the problems existing in the prior art, the present invention provides a schematic diagram of a high-efficiency PCB board lamination device for a production line, referring to... Figures 1 to 9 As shown, Figure 12 As shown, it includes a pressing assembly 1, a bearing base 6 at the bottom of the pressing assembly 1, a roller conveyor 4 outside the bearing base 6, two columns 3 are assembled and connected to the top of each of the two sides of the roller conveyor 4, the top of the four columns 3 are assembled and connected to the same cross frame 2, a coordinating positioning assembly 7 is provided between the cross frame 2 and both ends of the bearing base 6, a carrying rack 5 is movably connected to the top of the roller conveyor 4, and guide side plates 10 are assembled and connected to the top of both ends of the bearing base 6. Both cooperative positioning components 7 include a suspension plate frame 701. A drive rack 708 is provided on the side of the suspension plate frame 701 facing the center of the support base 6. Both sides of the drive rack 708 are meshed with drive gears 704. A driven gear 703 is meshed on the side of the drive gear 704 away from the drive rack 708. A limit clamping arm 702 is assembled and connected on the side of the driven gear 703 away from the suspension plate frame 701. A protrusion 709 is integrally formed on the surface of the side of the drive rack 708 facing the suspension plate frame 701. A pressure plate 705 is slidably connected inside the side of the suspension plate frame 701 facing the center of the support base 6. A first guide rod 707 is pin-connected inside the pressure plate 705. A second spring 706 is sleeve-connected to the outside of the first guide rod 707. The pressing assembly 1 includes a pressing cylinder 101. The bottom of the movable end of the pressing cylinder 101 is assembled with an assembly base 105. The bottom of the assembly base 105 is assembled with a pressing seat plate 103. The top of each of the four corners of the pressing seat plate 103 is assembled with a first positioning rod 102. A synchronous pressing frame 108 is assembled between the two first positioning rods 102 located at one end of the cross frame 2. The synchronous pressing frame 108 is Y-shaped. The first positioning rods 102 are slidably connected inside the cross frame 2. The shelf 5 includes a base plate 502, and positioning side frames 501 are assembled and connected to the top of both ends of the base plate 502. The protrusion 709 is slidably connected to the inside of the pressure plate 705 and the outside of the first guide rod 707. The second spring 706 is supported between the top of the pressure plate 705 and the top of the protrusion 709. By positioning the end of the synchronous pressure frame 108 away from the first positioning rod 102 at the top of the pressure plate 705, when the pressing cylinder 101 controls the assembly base 105 to drive the pressing seat plate 103 to move to the bottom under the guidance of the four first positioning rods 102, the synchronous pressure frame 108 presses against the pressure plate 705. The top pressure of 05 causes the pressure plate 705 to press against the protrusion 709 on the drive rack 708 by means of the second spring 706, which causes the drive rack 708 to drive the two drive gears 704 to rotate, thereby driving the driven gear 703 to drive the limiting clamp arm 702 to rotate slightly. Finally, the pressing assembly 1 presses the PCB board on the top of the base plate 502, and the end of the limiting clamp arm 702 away from the suspension plate frame 701 abuts against the positioning side frame 501, which restricts the movement of the rack 5 on the top of the support base 6. Meanwhile, after the two limiting clamping arms 702 on a collaborative positioning component 7 clamp the two ends of the positioning side frame 501, the pressing cylinder 101 continues to control the assembly base 105 and the pressing seat plate 103 to move to the bottom, and uses the first positioning upright 102 to drive the synchronous pressing frame 108 to apply pressure to the top of the pressing upright plate 705, so that the second spring 706 is compressed, maintaining the state of the two limiting clamping arms 702 clamping the positioning side frame 501, and not affecting the PCB board pressing work that the pressing seat plate 103 continues to move to the bottom; Secondly, to prevent damage to the PCB board caused by the pressure plate 103 applying pressure to the bottom of the PCB board under the control of the pressure cylinder 101, such as... Figure 4 As shown, a pressing panel 104 is provided at the bottom of the pressing base plate 103. Second positioning rods 107 are welded to the top of the four corners of the pressing panel 104. A first spring 106 is sleeved to the outside of the second positioning rods 107. The first spring 106 is supported between the pressing base plate 103 and the pressing panel 104. Bolts are welded to both long sides of the pressing panel 104. The bolts are slidably connected to the inside of the pressing base plate 103. Nuts are threaded to the outside of the bolts to prevent the bolts from coming out of the inside of the pressing base plate 103. The pressing panel 104 can be assembled to the bottom of the pressing base plate 103. When the pressing cylinder 101 applies pressure to the PCB board using the mounting base 105, the pressing base plate 103, and the pressing panel 104, the first spring 106 can be compressed to reduce the pressure between the pressing base plate 103 and the pressing panel 104, thus preventing the PCB board from being damaged by pressure. In some examples, a locking assembly 12 is provided between the top of both ends of the two suspension plate frames 701 and the bottom of the cross frame 2. The locking assembly 12 includes a fixed plate 1201, a movable plate 1202 slidably connected to the bottom of the fixed plate 1201, two sides of the movable plate 1202 bending down to form hooks 1208, a first seat plate 1204 bending down in the middle of the movable plate 1202, a second seat plate 1205 bending down in the middle of the fixed plate 1201 and passing through the interior of the movable plate 1202, a fifth guide rod 1206 threadedly connected to the interior of the second seat plate 1205, and a fourth spring 1207 sleevedly connected to the exterior of the fifth guide rod 1206. A hook block 1203 is assembled between the two hook bars 1208. An isosceles trapezoidal groove is provided on the top of the suspension plate frame 701. Positioning slots 14 are provided on both inner walls of the isosceles trapezoidal groove and are located inside the suspension plate frame 701. The cross sections of the positioning slots 14 and the hook block 1203 are both right trapezoidal. The fifth guide rod 1206 is slidably connected inside the first base plate 1204, and the fixed plate 1201 is assembled and connected to the bottom of the cross frame 2. When the suspension plate 701 applies pressure to the inclined surface of the two hook blocks 1203 at the top, the hook blocks 1203 use the hook bar 1208 to drive the first base plate 1204 to compress the fourth spring 1207. The fourth spring 1207 stores pressure to make the hook blocks 1203 reach the positioning slot 14. The hook blocks 1203 are adapted to be connected inside the positioning slot 14 to prevent the suspension plate 701 and the locking component 12 from disengaging. When the locking component 12 is assembled and fixed to the bottom of the cross frame 2, the co-positioning component 7 can be assembled to the bottom of the cross frame 2, and the disassembly of the co-positioning component 7 is facilitated. Secondly, to ensure that the collaborative positioning component 7 is vertically installed to the bottom of the crossbeam 2, such as... Figure 8 As shown, two positioning sliders 13 are provided on the inner side wall of the long side of the cross frame 2. The top of both ends of the suspension plate frame 701 are integrally formed with second guide rods 710. By making the two second guide rods 710 slide and connect to the two opposing positioning sliders 13 respectively, the vertical up and down movement of the suspension plate frame 701 can be guaranteed.

[0022] In this embodiment, the pressing cylinder 101 controls the assembly base 105 to drive the pressing plate 103 (guided by four first positioning rods 102) to move to the bottom. The synchronous pressing frame 108 applies pressure to the top of the pressing plate 705, so that the pressing plate 705 applies pressure to the protrusion 709 on the drive rack 708 by means of the second spring 706. When the drive rack 708 drives the two driving gears 704 to rotate, the driven gear 703 drives the limiting clamping arm 702 to rotate slightly. Finally, the end of the limiting clamping arm 702 away from the suspension plate frame 701 abuts against the positioning side frame 501, clamping and fixing the positioning side frame 501, thus restricting the movement of the carrier 5 on the top of the bearing base 6. Meanwhile, as the pressing cylinder 101 continuously controls the assembly base 105 and the pressing seat plate 103 to move the pressing panel 104 to the bottom, the first positioning rod 102 drives the synchronous pressing frame 108 to apply pressure to the top of the pressing plate 705, so that the second spring 706 is compressed. Under the condition that the two limiting clamping arms 702 hold the positioning side frame 501, the pressing seat plate 103 can continue to move to the bottom with the help of the pressing panel 104 to perform PCB board pressing work.

[0023] Example 2: Based on Example 1, this application's embodiment describes the control state when the shelf 5 is transferred to the top of the support base 6. The overall concept is as follows: like Figure 2 , Figure 3 , Figure 5 , Figures 9 to 12 As shown, the top of the support base 6 is provided with a movable slot 9, and two support rollers 8 are provided on the inner side of the support base 6. The same roller support frame 715 is provided on the outer side of both ends of the two support rollers 8. Two first limiting grooves 17 are provided in the inner side of both ends of the support base 6. A motor 11 is assembled and connected to one end of one support roller 8. Two slides 16 are assembled and connected to the side of the motor 11 near the support base 6. A positioning slider 13 is integrally formed on the surface of the side of the slides 16 away from the motor 11. Two second limiting grooves 18 are provided in the inner side of one corner of the support base 6. The two support rollers 8 protrude upward inside the movable slot 9 to guide the load rack 5 to transfer from the roller conveyor 4 to the top of the two support rollers 8. The motor 11 is located in the direction where the load rack 5 is transferred to the top of the two support rollers 8. One side of each of the two positioning sliders 13 is assembled and fixed to the roller support frame 715. By having the two ends of the bearing roller 8 pass through the interior of the two roller support frames 715 and extend into the interior of the two opposing first limiting grooves 17, and the two positioning sliders 13 are slidably connected to the interior of the two second limiting grooves 18, the two roller support frames 715 can support the two bearing rollers 8 to move up and down. Secondly, in order to support the two bearing rollers 8 protruding from the top surface of the bearing base 6 inside the movable slot 9, as follows: Figure 9 and Figure 10 As shown, the bottom inner wall surfaces at both ends of the bearing base 6 are integrally formed with support strips 15. The interior of the center of each of the two roller bearing frames 715 is provided with two fourth guide rods 714. The exterior of each of the two fourth guide rods 714 is sleeved with a third spring 713. By connecting the bottom of the fourth guide rod 714 to the interior of the support strip 15 with threads, and with the help of the third spring 713, it can be supported between the roller bearing frame 715 and the support strip 15, so that the two roller bearing frames 715 can support the two bearing rollers 8 at a fixed height. Furthermore, in order to control the assembly base 105 to move the pressing plate 103 to the bottom using the pressing cylinder 101, when the first positioning rod 102 drives the synchronous pressing frame 108 to apply pressure to the top of the pressing plate 705, the two bearing rollers 8 are simultaneously controlled to move to the bottom and retract into the inner side of the bearing base 6, so that when the shelf 5 is on top of the bearing base 6, it is not affected by the rotating bearing base 6. Figure 9 and Figure 11 As shown, a pressure sleeve 711 is integrally formed on the bottom surface of the pressure plate 705 on the side away from the center of the bearing base 6. An upright arm 716 is assembled to the outside of the pressure sleeve 711. A second guide rod 710 is integrally formed at the bottom of the upright arm 716. A third guide rod 712 and the pressure sleeve 711 are sleeved on the outside of the second guide rod 710. By supporting the third guide rod 712 between the upright arm 716 and the pressure sleeve 711, when the pressure plate 705 moves to the bottom, it drives the upright arm 716 to the bottom. The movement applies pressure to the top of the roller support frame 715 via the pressure sleeve 711. After the two third springs 713 are compressed, the roller support frame 715 carries the two support rollers 8 and retracts them into the inner side of the support base 6, so that the top of the support rollers 8 does not contact the bottom of the carrier 5 (during this process, the two ends of the support rollers 8 slide inside the first limiting groove 17, while the positioning slider 13 slides inside the second limiting groove 18, and the motor 11 moves with the two support rollers 8 because it is assembled and fixed with the slide 16). Meanwhile, by supporting the third guide rod 712 between the upright arm 716 and the pressure sleeve 711, the second guide rod 710 is movably connected to the inside of the roller support frame 715 and the support strip 15, and the pressure sleeve 711 is movably connected to the inside of the guide side plate 10 and the support base 6. When the roller support frame 715 is pressed and supports the two support rollers 8 to move to the bottom, the third guide rod 712 is compressed. This does not affect the subsequent pressing cylinder 101 applying pressure to the PCB board through the pressing seat plate 103 and the pressing panel 104.

[0024] In this embodiment, because the third spring 713 is supported between the roller support frame 715 and the support bar 15, the two roller support frames 715 can support the two support rollers 8 at a fixed height. The two roller support frames 715 support the two support rollers 8 on the inner side of the movable slot 9, protruding from the top surface of the support base 6. The vertical arm 716 assembled to the bottom of the pressure plate 705 applies pressure to the pressure sleeve 711 with the help of the third guide rod 712. The pressing cylinder 101 controls the assembly base 105, the pressing seat plate 103, and the pressing panel 104 to move to the bottom. During the process, the third guide rod 712 first transmits pressure to push the roller support frame 715 to the bottom using the pressure sleeve 711, compressing the two third springs 713, so that the roller support frame 715 carries the two support rollers 8 to the bottom and moves into the inner side of the support base 6, so that the top of the support rollers 8 does not contact the bottom of the carrier 5. Then the third guide rod 712 is compressed between the pressure sleeve 711 and the upright arm 716, without affecting the pressing cylinder 101 to perform the PCB board pressing work through the assembly base 105, pressing seat plate 103, and pressing panel 104.

[0025] Specifically, when using this device to perform operations: First, the third spring 713 is used to support the roller support frame 715 and the support bar 15, so that the two roller support frames 715 can support the two support rollers 8 at a fixed height, and the two roller support frames 715 support the two support rollers 8 on the inside of the movable slot 9 and protrude on the top surface of the support base 6. Then, the rack 5 is conveyed to the top of the support base 6 by the roller conveyor 4, and the support roller 8 driven by the motor 11 guides the base plate 502 to move towards the top of the support base 6. At the same time, the rack 5 moves to the center of the top of the support base 6 by means of two guide side plates. Subsequently, the pressing cylinder 101 controls the assembly base 105 to drive the pressing seat plate 103 to move to the bottom. With the help of the synchronous pressing frame 108, pressure is applied to the top of the pressing plate 705, so that the pressing plate 705 applies pressure to the protrusion 709 on the driving rack 708 with the help of the second spring 706. When the driving rack 708 drives the two driving gears 704 to rotate, the driven gear 703 drives the limiting clamping arm 702 to rotate slightly. Finally, the end of the limiting clamping arm 702 away from the suspension plate frame 701 abuts against the positioning side frame 501 to clamp and fix the positioning side frame 501. Meanwhile, the upright arm 716 assembled to the bottom of the pressure plate 705 applies pressure to the pressure sleeve 711 with the help of the third guide rod 712. The pressure is transmitted by the third guide rod 712, causing the pressure sleeve 711 to push the roller support frame 715 to move to the bottom, compressing the two third springs 713, so that the roller support frame 715 carries the two support rollers 8 to move to the bottom and is retracted into the inner side of the support base 6, so that the top of the support rollers 8 does not contact the bottom of the frame 5. Immediately afterwards, the first positioning rod 102 drives the synchronous pressing frame 108 to apply pressure to the top of the pressing plate 705, which compresses the second spring 706. While the two limiting clamping arms 702 hold the positioning side frame 501, the supporting pressing base plate 103 continues to move to the bottom with the help of the pressing panel 104 to perform PCB board pressing work. Meanwhile, the third guide rod 712 is compressed between the pressure sleeve 711 and the upright arm 716, which does not affect the pressing cylinder 101 from performing the PCB board pressing work through the assembly base 105, the pressing seat plate 103, and the pressing panel 104.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
