With the rapid development of the electronics industry, demand for ACLs is increasing, and the requirements for product performance are also becoming increasingly demanding. Traditional production processes often rely on manual operation or semi-automated equipment for lamination, which is not only inefficient but also difficult to ensure consistent and stable product quality.

Therefore, they cannot be understood as limiting the present invention.

[0028] Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The technical solutions of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. It should be noted that the technical features involved in the different embodiments of the present invention described below may be combined with one another as long as they do not conflict with one another.

[0029] Example 1: An automatic pressing device for producing aluminum-based copper-clad laminates, such as Figure 1 、 Figure 2 、 Figure 3 and Figure 7As shown, it includes a base frame 1 and a pressure plate 2. The base frame 1 is the load-bearing carrier of the pressing equipment. The top of the base frame 1 is fixedly connected to the pressure plate 2. The pressure plate 2 is used to place the plates to be pressed (aluminum base plate and copper plate); it also includes a pillar 3 fixedly installed on one side of the pressure plate 2. The top of the pillar 3 is fixedly connected to the side facing the pressure plate 2. The bottom of the top frame 4 is fixedly assembled with a hot pressing plate 6 through a hydraulic cylinder 5. The hot pressing plate 6 is located just above the pressure plate 2. The hot pressing plate 6 is used to press the stacked plates on the pressure plate 2. The pressure plate 2 is close to the pillar 3. A positioning plate 7 is provided at the top corner edge of the side. The positioning plate 7 is an "L"-shaped plate with a vertical angle. The positioning plate 7 is used to regularize and align the stacked plates on the pressure plate 2. The positioning range of the positioning plate 7 is larger than the hot pressing range of the hot pressing plate 6. A feeding mechanism 8 for conveying the plates is provided on both sides of the base frame 1 away from the top corner of the positioning plate 7; the feeding mechanism 8 includes a fixed block 81 fixedly connected to the bottom surface of the pressure plate 2, and a rodless cylinder 82 is fixedly installed on the fixed block 81. The two rodless cylinders 82 on the base frame 1 are vertically distributed, and the rodless cylinders 82 slide on Assemble the slider 83, the top of the slider 83 is fixedly connected to the mounting plate 84, and the mounting plate 84 is equipped with a roller conveyor 9. The first cylinder 85 is fixedly installed on both sides of the bottom surface of the mounting plate 84. The piston rods of the first cylinder 85 are all upwardly penetrated through the mounting plate 84 and connected to the roller conveyor 9. When the roller conveyor 9 is synchronously driven by the first cylinder 85 to be lifted up to the pressure plate 2, the rodless cylinder 82 drives the roller conveyor 9 on the mounting plate 84 to move toward the top surface of the pressure plate 2 of the base frame 1 through the slider 83. According to the actual pressing size of the plate , adjust the two roller conveyors 9 on the pressure plate 2 to the appropriate feeding position and then stop, and use the two roller conveyors 9 to transfer the aluminum substrate and copper plate and other plates to be pressed to the pressure plate 2 in the pressing order. Under the folding angle of the positioning plate 7 and the square limit of the two roller conveyors 9, the plates can be accurately stacked on the pressure plate 2, saving the work of repeatedly aligning the newly stacked plates when pressing the multi-layer composite plates. Finally, use the hydraulic cylinder 5 to drive the hot pressing plate 6 to press down on the plate on the pressure plate 2 to complete the hot pressing operation of the aluminum-based copper clad plate.

[0030] like Figure 3-Figure 5As shown, the roller conveyor 9 includes a fixed plate 91 installed on the top of the mounting plate 84, and the piston rod of the first cylinder 85 passes through the mounting plate 84 and is connected to the fixed plate 91. Side plates 92 are installed on both sides of the fixed plate 91, and multiple drive shafts 93 are installed at intervals between the side plates 92 on both sides. A synchronous wheel 931 is fixedly installed on one side of the roller body of the drive shaft 93, and a synchronous belt 94 is wrapped around the periphery of the synchronous wheel 931. A transmission cylinder 95 is assembled on the drive shaft 93, and a motor 96 is fixedly installed on the outer side of the side plate 92 on one side. The output shaft of the motor 96 is connected to one of the drive shafts 93, and the motor 96 drives one of the drive shafts 93. Through the synchronous wheel 931 and the synchronous belt 94, each drive shaft 93 between the side plates 92 can synchronously drive the transmission cylinder 95 to rotate, so that the transmission cylinder 95 can smoothly transport the placed plates to the pressure plate 2 for stacking.

[0031] like Figure 6 As shown, the top frame 4 is an "I"-shaped frame and is fixedly equipped with multiple hydraulic cylinders 5. The piston rods of the hydraulic cylinders 5 are all connected to the hot pressing plate 6. The multiple hydraulic cylinders 5 synchronously drive the hot pressing plate 6 to press it downward on the pressure plate 2, so that the hot pressing plate 6 can apply uniform pressure to various positions of the plate for hot pressing, thereby improving the quality of the hot pressing of the plate.

[0032] like Figure 3 、 Figure 4 and Figure 9 As shown, a limiting plate 10 is assembled at the end of the fixed plate 91 facing the pressure plate 2, and a group of transmission cylinders 95 close to the pressure plate 2 are tangent between the plate surface of the limiting plate 10 and the side plate 92, and the limiting plates 10 on the two roller conveyors 9 are perpendicular to each other. When the rodless cylinder 82 drives the roller conveyor 9 to move on the pressure plate 2, the limiting plate 10 at the end of the roller conveyor 9 cooperates with the positioning plate 7 to form a square limiting area on the pressure plate 2 according to the size of the stacked plates, so that the plates can be accurately aligned and stacked on the pressure plate 2.

[0033] like Figure 1 and Figure 6 As shown, the hot pressing plate 6 is composed of a pressure plate 61 and an electric heating tube 62. The pressure plate 61 is connected to the piston rods of multiple hydraulic cylinders 5 on the top frame 4. The top surface of the pressure plate 61 is curved and provided with an electric heating tube 62. The electric heating tube 62 is evenly arranged on the pressure plate 61. After the electric heating tube 62 is energized, the heat is evenly transferred to the pressure plate 61, so that the pressure plate 61 can efficiently and evenly heat the insulating medium layer between the plate materials, thereby ensuring the consistency of the pressing quality of each finished plate.

[0034] like Figure 2 and Figure 8As shown, a slide groove 31 is provided in the pillar 3, and an electric push rod 72 is fixedly installed on one side of the pillar 3. The piston rod of the electric push rod 72 is connected to the positioning plate 7 through a connecting rod 71. The connecting rod 71 is located in the slide groove 31 of the pillar 3. The electric push rod 72 is used to drive the positioning plate 7 to lift on the pressure plate 2. When the plate is pressed on the pressure plate 2, the electric push rod 72 drives the limit plate 10 to lift and disengage from the pressure plate 2 through the connecting rod 71. The limit plate 10 is not on the pressure plate 2 to limit the finished plate, thereby facilitating the discharge of the pressed finished plate from the pressure plate 2.

[0035] When using this automatic pressing equipment to press aluminum-based copper-clad laminates, the operator first adjusts the position of the feeding mechanism 8 according to the specifications of the sheets to be pressed, and first synchronously pushes the roller conveyor 9 to the height flush with the pressure plate 2 through the first cylinder 85 on the two mounting plates 84, so that the fixed plate 91 of the roller conveyor 9 can slide and fit on the top surface of the pressure plate 2, and then activates the rodless cylinders 82 on both sides, and drives the corresponding sliders 83 to slide horizontally or vertically along the base frame 1 respectively through the rodless cylinders 82. The sliders 83 drive the roller conveyor 9 on the mounting plate 84 to move to the position of the size of the sheet to be pressed on the top surface of the pressure plate 2, and ensure that the feeding path accurately corresponds to the stacking area on the pressure plate 2. After completing the preliminary positioning, the operator places the aluminum substrate and copper sheet coated with the insulating dielectric layer on the roller conveyors 9 at the two locations in the pressing order. After starting the motor 96, the drive shaft 93 rotates synchronously through the synchronous belt 94 to link all the transmission cylinders 95 The plate is rotated and smoothly transported to the surface of the pressure plate 2. During the movement of the plate from the roller conveyor 9 to the pressure plate 2, the plate that slides onto the pressure plate 2 is constrained by the "L"-shaped corner of the positioning plate 7 and the vertical limit plates 10 at the ends of the roller conveyors 9 on both sides, and is gradually stacked into a multi-layer structure with neat edges. When all the pressed plates are stacked on the pressure plate 2, the rodless cylinders 82 on both sides are controlled to adjust the position of the roller conveyor 9 according to the size of the pressed plates, so that the roller conveyor 9 can avoid the downward pressure stroke of the hot pressing plate 6. Then the hot pressing plate 6 is synchronously driven downward by multiple hydraulic cylinders 5 on the top frame 4, and the evenly distributed electric heating tubes 62 in the pressure plate 61 of the hot pressing plate 6 are energized and heated, and heat and pressure are applied to the stacked layers of plates at the same time. Under constant temperature and balanced pressure, the insulating medium layer between the plates gradually melts and solidifies, realizing a close combination of the aluminum base and the copper plate, ensuring the flatness and bonding strength of the plates after pressing.

[0036] Example 2: Based on Example 1, Figure 2 、 Figure 8 and Figure 9As shown, a discharge mechanism 11 is provided on the pressure plate 2, and the discharge mechanism 11 includes a support plate 111, a second cylinder 112 and a lifting plate 113. A plurality of openings are spaced apart on the surface of the pressure plate 2. The bottom surface of the pressure plate 2 is fixedly connected to the support plate 111. A second cylinder 112 having the same number of openings as the pressure plate 2 is fixedly installed on the support plate 111. A lifting plate 113 is installed on the piston rod of the second cylinder 112. The lifting plates 113 are respectively slidably embedded in the openings of the pressure plate 2. The top surface of the lifting plate 113 is initially flush with the surface of the pressure plate 2. When discharging, the electric push rod 72 first drives the positioning plate 7 to separate from the pressure plate 2, and controls the extension of the piston rod of the second cylinder 112 at the appropriate position according to the size of the finished pressed plate. The second cylinder 112 drives the lifting plate 113 to lift one side of the finished plate upward from the opening of the pressure plate 2. After being lifted, the finished plate will slide out from the pressure plate 2 at an angle, and finally the slid-out finished plate can be collected through the collection container.

[0037] like Figure 5 and Figure 10 As shown, the transmission cylinders 95 assembled between the side plates 92 of the roller conveyor 9 are set as two symmetrical groups, the drive shaft 93 is a spline shaft, and the two groups of transmission cylinders 95 and the corresponding drive shafts 93 are splined. The two groups of transmission cylinders 95 and the side plates 92 on the same side are rotatably matched, and the side plate 92 where the motor 96 is located and the fixed plate 91 are fixedly connected. The side of the fixed plate 91 away from the limit plate 10 is fixedly equipped with a multi-stage push rod 12, and the push rod of the multi-stage push rod 12 is connected to the side plate 92 away from the motor 96. The side plate 92 is driven to move by the multi-stage push rod 12, so that the spacing between the two groups of transmission cylinders 95 on the side plate 92 can be changed along the drive shaft 93, so that the transmission cylinder 95 of the roller conveyor 9 can adapt to the transportation of plates of different sizes.

[0038] After the pressing operation of the multi-layer sheet is completed, the hot pressing plate 6 is driven by the hydraulic cylinder 5 to lift and reset to the initial height, and the electric push rod 72 is activated at the same time. The electric push rod 72 drives the positioning plate 7 on the pressure plate 2 through the connecting rod 71 to gradually lift up from the edge of the sheet and separate from the pressure plate 2, thereby releasing the top angle limit of the finished sheet. Then the discharging mechanism 11 is started, and the operator selects the opening position corresponding to the bottom of the pressure plate 2 according to the size of the finished product, and controls the second cylinder 112 at the appropriate position to push the lifting plate 113 upward from the opening of the pressure plate 2, so that one side of the finished sheet on the pressure plate 2 is lifted and forms an inclined angle. Under the action of gravity, the sheet slides away from the pressure plate 2 along the inclined surface and falls into a preset collection device or a conveyor belt for subsequent processing, completing the automatic discharging. If it is necessary to change the production specifications of different plates, the operator can adjust the spacing between the two sets of transmission cylinders 95 on the roller conveyor 9 through the multi-stage push rod 12 to adapt to plates of different widths. At the same time, the rodless cylinder 82 re-drives the roller conveyor 9 to move to the newly set feeding position on the pressure plate 2 to ensure the accurate stacking of the next batch of plates. At the same time, the positioning plate 7 is reset to the edge of the pressure plate 2 under the drive of the electric push rod 72, and the hot pressing plate 6 re-enters the standby state, so that the equipment is ready to enter a new round of pressing operation. The whole process takes into account the dual needs of efficient production and flexible changeover through mechanical limit, automatic transmission and modular adjustment, avoiding the trouble of repeated adjustment of positioning when pressing multi-layer plates of different sizes, and significantly improving the pressing production efficiency of aluminum-based copper clad laminates.
