Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of aluminum substrate production and processing, and in particular to intelligent aluminum-based copper-clad laminate pressing and molding equipment. Background Art
[0002] Aluminum-based copper-clad laminate (also known as aluminum substrate) is a type of raw material. It is made of electronic fiberglass cloth or other reinforcing materials impregnated with resin or a single resin as an insulating adhesive layer, coated on one or both sides with copper foil, and then hot-pressed. This sheet material is called a copper-clad aluminum laminate, or simply aluminum-based copper-clad laminate. As the substrate material in printed circuit board (PCB) manufacturing, aluminum-based copper-clad laminate primarily serves as interconnect, insulation, and support for the PCB, significantly affecting signal transmission speed, energy loss, and characteristic impedance within the circuit. The performance, quality, processability, manufacturing level, manufacturing cost, and long-term reliability and stability of the PCB depend heavily on the aluminum-based copper-clad laminate. However, the production and processing structure of traditional aluminum-based copper-clad laminates is simple, resulting in poor performance.
[0003] The published patent "CN 111452481 B, an aluminum substrate foil pressing device" records that "the present invention relates to the field of aluminum substrate production and processing, and specifically to an aluminum substrate foil pressing device, comprising a positioning table, a loading assembly for feeding the aluminum substrate, a transmission assembly for feeding the copper foil, a pressing assembly, a discharge conveyor belt and four first photoelectric sensors for positioning and pressing between the aluminum substrate and the copper foil. The positioning table is arranged between the loading assembly and the transmission assembly, and the feeding direction of the loading assembly is perpendicular to the feeding direction of the transmission assembly. The pressing assembly is arranged on the side of the transmission assembly. The four first photoelectric sensors are all arranged on the pressing assembly. The positioning table and the transmission assembly are also provided with four second photoelectric sensors corresponding to each first photoelectric sensor. The loading assembly includes a loading conveyor belt. The present invention solves the problem of inaccurate fitting between the aluminum substrate and the copper foil, improves the accuracy of pressing between the aluminum substrate and the copper foil, and improves the production efficiency of the aluminum substrate."
[0004] However, the aluminum substrate pressing device of the prior art still has the following shortcomings: First, although the aluminum substrate pressing device of the prior art has solved the problem of inaccurate lamination to a certain extent, it is bulky in structure, complicated to operate, and relatively troublesome to transport. The equipment occupies a large space and has low space utilization, which has caused a sharp increase in equipment manufacturing costs and processing costs, and the cost-effectiveness is not high. Furthermore, it is impossible to reasonably coordinate and manage the transportation of substrates and copper foil, the cleaning of raw materials, glue coating-squeegeeing, positioning and tightening-pressing, adjusting the copper foil cutting area and pressing temperature control. At the same time, the aluminum substrate pressing device of the prior art lacks the adaptability to process aluminum substrates of different sizes. That is, it can only process aluminum substrates of a single model and cannot arbitrarily adjust and cut the copper foil to adapt to the production of aluminum substrates of different models and specifications.
[0005] Second, existing aluminum substrate laminating devices have a simple structure and inadequate cleaning of the substrate and copper foil. Dust or impurities on the copper foil and substrate surfaces can easily cause bubbles to form during lamination, resembling bubbles on a cell phone screen protector, which negatively impacts the aesthetics and significantly reduces the quality of the copper-clad laminate. Third, as is well known, temperature and pressure are key factors influencing the lamination process. Existing aluminum substrate laminating devices have a simple structure and relatively simple temperature control. Excessively high or low temperatures can easily lead to insufficient lamination, impairing the quality of the aluminum substrate, and making it difficult to ensure consistent production and processing. Therefore, in order to achieve not only improved cost-effectiveness of equipment production and processing, but also rapid and convenient adjustment to accommodate the production and processing requirements of various aluminum substrate models and specifications, while also pre-treating and cleaning the substrate and copper foil raw materials and intelligently adjusting and controlling the temperature required for lamination, an intelligent aluminum-based copper-clad laminate laminating molding device is needed. Summary of the Invention

[0036] Example: Figures 1 to 10 As shown:
[0037] An intelligent aluminum-based copper-clad laminate pressing and forming device, the pressing and forming device comprises a support frame 1 and a conveying structure 2. The support frame 1 is distributed left and right, such as Figure 1 As shown: In this embodiment, the support frame includes a support frame of a rectangular structure and support legs arranged at the lower end of the support frame. The conveying structure 2 is arranged on the support frame 1, and is configured to drive the substrate to move from left to right for transmission. Specifically, the conveying structure 2 includes an active roller 21, a driven roller 22, a transmission roller 23, a drive motor 24 and a conveyor belt 25. The active roller 21 is rotatably arranged on the right side of the support frame 1, and the driven roller 22 is rotatably arranged on the left side of the support frame 1. The transmission rollers 23 are evenly distributed in plurality and are arranged on the support frame 1, and are located between the active roller 21 and the driven roller 22. The drive motor 24 is arranged on the support frame 1, and the output shaft is connected to the active roller 21; the conveyor belt 25 is arranged between the active roller 21 and the driven roller 22. For details, refer to Figure 2 The drive motor adopts a servo control motor and is connected to a control switch. With this configuration, when the drive motor is started, it drives the active roller and the conveyor belt to rotate, thereby completing the movement of the substrate material.
[0038] like Figure 3As shown in this embodiment, a glue coating structure 3 is also provided on the support frame 1 for coating the substrate with glue, facilitating the lamination and forming between the copper foil and the substrate. This avoids the inconvenience of manual glue coating or automated glue coating on a glue coating production line requiring transfer and lamination. The glue coating structure 3 comprises a photoelectric sensor a31, a glue coating frame 32, a glue coating box 33, a liquid pump 34, a glue coating nozzle 35, and a glue scraper 36. The photoelectric sensor a31 is mounted on the support frame 1 and electrically connected to the liquid pump 34. It detects whether the substrate has moved to a designated position and determines whether to trigger the liquid pump to complete the glue coating process. The glue coating frames 32 are arranged front and back on the support frame 1, and the glue coating box 33 is mounted on the glue coating frame 32, perpendicular to the direction of substrate transport. The glue coating box's input is connected to an external glue source via a liquid infusion tube 37. The liquid pump 34's input is connected to the liquid infusion tube 37, and its output is connected to the glue coating box 33. Multiple glue coating nozzles 35 are evenly distributed throughout the glue coating box 33. In this embodiment, an electromagnetic flow control valve can also be installed at the connection of the glue spray nozzle, and the electromagnetic flow control valve also maintains a signal connection with the photoelectric sensor a, thereby achieving precise glue flow control. With this configuration, when the photoelectric sensor a detects that the substrate has reached a specified position, namely the right end of the substrate, a trigger starts the start signal to the liquid pump, which begins to drive the glue liquid to the glue spray nozzle. The substrate maintains uniform movement, and the glue spray nozzle sprays a preset amount of glue onto the substrate, thereby improving the lamination effect and processing quality between the copper foil and the substrate.
[0039] Among them, Figure 4 As shown: the scraper 36 is used to evenly spread the glue on the aluminum substrate. The scraper 36 includes a fixed plate 361, a scraper plate 362 and an adjustment part 363. The fixed plate 361 is horizontally distributed and one end is fixedly connected to the glue coating frame 32; the fixed plate is located on the right side of the glue coating frame. The scraper plate 362 is movably arranged on the fixed plate 361 through the adjustment part 363. In this embodiment, the scraper plate is mainly composed of a scraper distributed above and a scraper distributed below. Specifically, the adjustment part 363 includes an adjustment motor 364, a rotating shaft 365, an adjustment gear 366 and a rack 367. The adjustment motor 364 is arranged on the fixed plate 361, and the adjustment motor also adopts a servo control motor to facilitate precise control of the movement amount. Of course, in this embodiment, manual adjustment can also be adopted by replacing the adjustment motor with a handwheel, which will not be repeated here.
[0040] Furthermore, the rotating shaft 365 is rotatably arranged in the fixed plate 361 and maintains a front-to-back distribution. The adjusting gear 366 is sleeved and installed on the rotating shaft 365; the rack 367 is arranged on the scraper plate 362, and the adjusting gear 366 and the rack 367 are kept in meshing transmission; a scale indicator line is also provided on one side of the scraper plate 362. The purpose of such a setting is that the glue coating thickness required for substrates of different specifications and models is different. The staff will adaptively adjust the glue coating thickness according to the specifications and models of the substrates in the initial stage. Specifically, when the adjustment motor is started, it will drive the rotating shaft to rotate synchronously, and the adjustment gear on the rotating shaft will drive the scraper plate to move under the action of the meshing transmission. The forward and reverse movement of the adjustment motor will drive the scraper plate to move up and down, thereby adjusting the appropriate glue coating thickness requirement.
[0041] like Figure 2 As shown: In this embodiment, an electrostatic dust collector 4 is also installed on the support frame 1 on the left side of the glue coating frame 32 through a bracket; it is used to clean the raw material substrate below. Among them, the electrostatic dust collector 4 is arranged on the left side of the glue coating frame, so as to ensure the cleanliness of the substrate before glue coating. Electrostatic dust removal is a gas dust removal method. When the dust-laden gas passes through a high-voltage electrostatic field, it is electrically separated. After the dust particles combine with negative ions and carry negative charges, they tend to discharge and deposit on the anode surface. It is used to purify gas or recover useful dust particles in metallurgy, chemistry and other industries. A dust collection method that uses an electrostatic field to ionize the gas so that the dust particles are charged and adsorbed on the electrode. In a strong electric field, air molecules are ionized into positive ions and electrons. When the electrons rush to the positive electrode, they encounter dust particles, causing the dust particles to be negatively charged and adsorbed to the positive electrode and collected.
[0042] like Figure 1 As shown: A positioning and fastening structure 5 is provided on one side of the support frame 1, and the positioning and fastening structure is located on the right side of the glue coating frame. The positioning and fastening structure 5 is configured to complete the positioning and fastening of the aluminum substrate when the aluminum substrate is transported and moved to the preset position of the support frame 1. Specifically, as Figure 5 As shown, the positioning and securing structure 5 comprises a photoelectric sensor b51, a rotating lead screw 52, a rotating motor 53, a fixing rod 54, a connecting arm 55, and a securing plate 56. The photoelectric sensor b51 is positioned on one side of the support frame 1 and is used to detect when the aluminum substrate has reached a predetermined position and transmit a trigger signal to the rotating motor 53. The rotating lead screw 52 is rotatable and disposed front and rear on the support frame 1. The lead screw 52 is divided into two equal sections, with the threads of the front and rear sections rotating in opposite directions. The lead screw and the support frame are capable of relative rotation but not relative movement (achieved through keyway engagement).
[0043] like Figure 5As shown, the rotating motor 53 is mounted to the support frame 1 via a bracket, and its output shaft is connected to the rotating screw 52. The fixed rod 54 is rotatably mounted on the rotating screw 52 and maintained in a vertical position. A positioning rod 57 is also provided at the bottom of the fixed rod 54. The positioning rod 57 is arranged parallel to the rotating screw 52 and fixedly connected to the support frame 1. The positioning rod 57 and the fixed rod 54 can move relative to each other, thus ensuring that the fixed rod can only move in one direction. Simultaneously, the forward and reverse motion of the rotating screw drives both fixed rods to move inward or outward simultaneously. A connecting arm 55 is mounted on the fixed rod 54 at one end and connected to the securing plate 56 at the other end, which is arranged horizontally. The length of the connecting arm can also be adjusted telescopically, so that even if the fixed rod is located outside the support frame, the securing operation can be completed. The fixed rod 54, connecting arm 55, and securing plate 56 are arranged as two sets that are adapted to be mounted and symmetrically distributed front to back.
[0044] With such an arrangement, when the photoelectric sensor b detects that the substrate is transported to the pre-calibrated position of the positioning and fastening structure, it triggers the start of the drive motor and the rotating motor; the drive motor stops, and the conveyor belt and the substrate remain stationary. Synchronously, when the rotating motor starts, it will drive the rotating screw to rotate synchronously, so as to analyze the positioning and fastening movement of the substrate: when the rotating motor rotates forward, it will drive the rotating screw to rotate synchronously clockwise, and then drive the two symmetrically distributed fixed rods to move inward synchronously, that is, it will drive the two symmetrically distributed fastening plates to move synchronously to complete the positioning and fastening of the substrate. The structural design is reasonable and the operation is simple, which provides a favorable foundation for the subsequent pressing process. In this embodiment, the control method of the photoelectric sensor and the liquid pump, the drive motor, and the rotating motor can be realized by automatic control through a PLC controller; the control circuit and working principle of the PLC controller can be realized by simple programming by technicians in this field, which belongs to common knowledge in this field and will not be elaborated.
[0045] like Figure 6 As shown: In this embodiment, a fixing frame 6 is further provided in the middle of the support frame 1. The fixing frame 6 is in an L-shaped structure, and a hole is provided on one side of the fixing frame so as not to affect the transmission movement of the substrate on the conveyor belt. A vertically distributed telescopic arm 61 is also provided on the horizontal side of the fixing frame 6, and the telescopic arm extends downward. The telescopic arm 61 includes a telescopic sleeve 611, a telescopic rod 612 and a compression spring 613. One end of the telescopic sleeve 611 is connected to the fixing frame 6, and the other end is connected to the telescopic rod 612 through the built-in compression spring 613; the other end of the telescopic rod 612 is connected to the cutting plate 62. This arrangement is used to assist in driving the cutting plate to move up and down, thereby completing the cutting operation of the copper foil. The copper foil is very thin and only requires a small amount of pressure to cut.
[0046] like Figure 6As shown: The bottom end of the telescopic arm 61 is also connected to a cutting plate 62, which is a rectangular frame structure, and the lower end surface of the cutting plate 62 is also provided with a cutting knife 63 that can adapt to the aluminum substrate and adjust the cutting of the copper foil. Specifically, an adjustment structure 64 is also provided between the cutting plate 62 and the cutting knife 63. Figure 8 The figure shows an inverted installation of the cutting blade. The adjustment structure 64 includes a guide slot 641, a guide post 642, a bolt plate 643, and a securing bolt 644. The guide slot 641 defines the lower end surface of the cutting plate 62. The guide post 642 is mounted on the cutting blade 63 and is adapted to be mounted and movably disposed within the guide slot 641. The bolt plate 643 is mounted on one side of the guide post 642, and the two are integrally formed. The securing bolt 644 passes through the bolt plate 643 and is fixedly connected to the cutting plate 62, allowing the cutting blade 63 to move inward and outward. A scale 65 is also provided on one side of the guide slot 641, and a marking protrusion 66 is provided on one side of the bolt plate 643. The marking protrusion 66 has a triangular cross-section. This arrangement allows for adaptive adjustment of the area enclosed by the cutting blades by adjusting the distribution of the installed cutting blades, that is, the length and width of the corresponding substrate. Of course, there are many specifications and models of cutting knives. The staff can identify the substrate processing model in the initial stage to know the length and width of the substrate, and adjust the distribution of the cutting knife on the lower end surface of the cutting board accordingly.
[0047] like Figure 7 As shown: In this embodiment, a movable pressing structure 7 is also provided in the center of the cutting plate 62, and the pressing structure 7 includes a base 71, a heating plate 72, a resistance wire 73, a spring 74 and a clamping rod 75. The base 71 is horizontally distributed and connected to the fixed frame 6 through a cylinder 76; in this way, the cylinder can drive the base to move up and down. Among them, the cylinder is the main drive, the telescopic arm is auxiliary, and the movement of the cutting plate is the effect brought about by the movement of the cylinder. The heating plate 72 is arranged at the lower end of the base 71 and is made of graphite thermal conductive material; graphite is a high-temperature stable material with a very high thermal conductivity coefficient of up to 1600W / (m·K), so graphite is widely used in high heat conduction, high thermal conductivity and heat dissipation and other fields. With this arrangement, the base acts as a buffer to ensure that the force on the heating plate is avoided from impact. The heating plate uses graphite thermal conductive material, which makes the temperature control required for substrate processing and pressing more precise. In this embodiment, a guide structure is preferably provided between the cutting plate and the base. The guide structure includes a guide plate and a guide groove. The guide plate is provided on the base, and the guide groove is provided on one side of the cutting plate. The two are matched and installed to ensure the sliding stability between the base and the cutting plate. A baffle is also provided at the upper end of the cutting plate to limit the movement of the base.
[0048] The resistance wire 73 is arranged in the heating plate 72, and the temperature of the heating plate 72 is detected in real time by the temperature detection probe 78; the temperature detection probe is arranged on one side of the heating plate for temperature detection. The temperature detection probe is electrically connected to the resistance wire. In this embodiment, the control method of the temperature detection probe, the resistance wire and the cylinder drive is to achieve automatic control through a PLC controller; the working principle of the PLC controller is common knowledge in this field, so it will not be described in detail. Figure 7 As shown, the cutting plate 62 is provided with a slot 77 on the side opposite the base. A spring 74 is mounted in this slot, with one end connected to a lever 75. The lever 75 has inclined surfaces on both its upper and lower sides. Under normal conditions, the spring is naturally extended, with the majority of the lever positioned outside the slot. Initial contact between the base and the upper inclined surface of the lever creates sufficient friction. The spring's elastic force is sufficiently strong that, as the cylinder moves downward, the base moves downward simultaneously, leaving the cutting plate below the base in contact. During this process, the cutting plate and base move downward simultaneously until the cutting plate contacts the copper foil, encountering a certain amount of resistance. At this point, the cutting plate, thrust from above, gradually completes cutting the copper foil below and begins contacting the raw substrate. Simultaneously, the base continues to move downward under the action of the cylinder, and the base and cutting plate begin to move relative to each other. The downward movement of the base compresses the lever box, contracting until the base and heating plate move downward, completing the pressing of the copper foil and the raw substrate. During this pressing process, the temperature of the heating plate is controlled by a temperature detection probe and heating with a resistance wire. The overall downward pressure of the substrate and the heating plate is adjusted and controlled by the cylinder. At the same time, the cylinder can be connected to a time relay to complete the pressing for a preset time.
[0049] like Figure 9 As shown: In this embodiment, a conveying frame 8 is also provided on one side of the support frame 1. The conveying frame 8 is distributed front to back, and is provided with a rotatable main shaft 81, a middle shaft 82 and a secondary shaft 83 in sequence from back to front. That is, the conveying frame is distributed vertically to the support frame. Such an arrangement saves space while not delaying the continued transportation of the finished aluminum substrate after the pressing process, making the operation convenient and saving time and effort. The main shaft 81 is used to place the rolled copper foil and is connected to a first motor 85; with such an arrangement, the first motor drives the main shaft to rotate, releasing the copper foil raw material for transportation. The secondary shaft 83 is used to wind and recycle waste copper foil scraps and is connected to a second motor 86. In this embodiment, the height of the middle shaft is lower than the height of the main shaft, and the height between the secondary shaft and the middle shaft is level. Such an arrangement is conducive to the tensioning and straightening horizontal operation of the copper foil.
[0050] like Figure 10As shown, a cleaning member 84 is provided on one side of the central axis 82. This cleaning member 84 is configured to perform electrostatic dust removal during copper foil transport. Specifically, the cleaning member 84 comprises two symmetrical cleaning support plates 841, a cleaning box 842, a cleaning shaft 843, a third motor 844, and an electrostatic precipitator 845. The cleaning support plates 841 are symmetrically arranged and mounted on the conveyor frame 8, providing a stable support. The cleaning box 842 is positioned between the two cleaning support plates 841 and is hollow, specifically with an open bottom to facilitate air intake. The electrostatic precipitator 845 is housed within the cleaning box 842, which houses a dust bag. The output end of the electrostatic precipitator is connected to the dust bag for dust collection. The cleaning shaft 843 is rotatably mounted at the lower end of the cleaning box 842, below the electrostatic precipitator 845. The third motor 844 is positioned within the cleaning box 842, with its output shaft connected to the cleaning shaft 843. In this way, the third motor drives the cleaning shaft to rotate, thereby completing the surface cleaning of the copper foil.
[0051] Reference Figure 10 As shown: a cleaning sponge 87 is wrapped and installed on the cleaning shaft 843 and the middle shaft 82. The cleaning shaft is sleeved with a cleaning sponge and protrudes outward from the cleaning box, and the copper foil is transmitted between the cleaning shaft and the middle shaft. During the cleaning operation, the speed of the third motor is greater than the speed of the first motor and less than the speed of the second motor. The copper foil will not be torn off while ensuring sufficient tension. The rotation of the third motor will drive the rotation of the cleaning shaft, and the synchronous electrostatic precipitator will start working. The cleaning sponges on the cleaning shaft and the middle shaft will start to electrostatically remove dust from the top and bottom of the copper foil to ensure the cleaning effect of the copper foil. This provides a strong foundation for the subsequent efficient pressing of the copper foil and the substrate, avoiding the problem of bubbling and delamination of the aluminum substrate, which will directly affect the quality of the finished product. In this embodiment, the control method of the first, second, and third motors and the electrostatic precipitator can be achieved by button start control through a control switch; this is common knowledge in the field, and this application document is mainly used to protect the mechanical device, so this application will no longer explain the control method and circuit connection in detail.
[0052] This pressing and forming equipment has a rational structural design. By providing a horizontally conveyed substrate structure and a vertically distributed copper foil structure, it improves the space utilization rate for aluminum substrate pressing. At the same time, it streamlines the raw material conveying operation and adds structures such as raw material cleaning, which enables convenient replacement and installation of cutting knife models and specifications, allowing for the arbitrary adjustment and cutting of copper foil to adapt to the production of aluminum substrates of different models and specifications. It has greater adaptability and can produce and process aluminum substrates of various specifications and models, making it more practical. The raw material substrates are pre-treated and cleaned in the initial stage of conveying by an electrostatic dust collector. The rational design facilitates the uniformity and neatness of subsequent glue coating. At the same time, the coordination of the cleaning support plate, cleaning box, cleaning shaft, third motor and electrostatic dust collector further ensures the cleanliness of the copper foil during transportation, avoiding the appearance of dust, which can cause bubbles during the bonding process between the copper foil and the substrate, and affect the quality of the aluminum substrate pressing. At the same time, the company further adopts the coordination of a heating plate made of graphite thermal conductive material, a resistance wire, and a temperature detection probe. The temperature detection probe detects the temperature of the heating plate in real time, and the resistance wire heats more evenly. The heating plate uses graphite thermal conductive material with high thermal conductivity and more efficient thermal conductivity. This intelligent temperature control adjusts the pressing temperature, greatly improving the pressing quality and operating efficiency of the aluminum-based copper-clad laminate. At the same time, it also achieves the goal of rationally coordinating the transportation of substrates and copper foil, cleaning of raw materials, glue coating-squeegeeing, positioning and tightening-pressing, and pressing temperature control. This integrated, streamlined structural design completes the pressing and assembly process of the aluminum-based copper-clad laminate, improves the pressing quality and efficiency of the aluminum-based copper-clad laminate, and further enhances the intelligence and automation level of the aluminum-based copper-clad laminate pressing.
