Description

Technical Field

[0001] This utility model relates to the field of copper clad laminate production technology, specifically to a pre-pressing device for copper clad laminates. Background Technology

[0002] Copper clad laminate, also known as copper foil laminate or CCL for short, is a core upstream material in PCB manufacturing. It has a strong interdependence with PCB. The main material of printed circuit boards is copper clad laminate, which is composed of a substrate, copper foil, and adhesive. During its manufacturing, it often needs to be pre-pressed to make it more efficient for practical use.

[0003] In existing equipment, the inability to perform back-and-forth rolling pre-pressing results in incomplete internal pre-pressing, reducing the quality of the copper-clad laminate and consequently decreasing pre-pressing efficiency. Furthermore, the inability to stabilize the copper-clad laminate during pre-pressing leads to edge warping, causing damage and affecting its efficient use. Therefore, we propose a copper-clad laminate pre-pressing device to address these issues. Utility Model Content

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] Please see Figure 1-5 A pre-pressing device for copper-clad laminates includes a base 1, a fixing structure 2 on the upper surface of the base 1, support plates 3 fixedly installed at both ends of the upper surface of the base 1, and a pre-pressing structure 4 at the top of the support plates 3.

[0024] The fixing structure 2 is used to fix the copper-clad laminate, and the pre-pressing structure 4 is used to pre-press the copper-clad laminate by rolling it back and forth.

[0025] Reference Figure 1-3As shown, the fixed structure 2 includes a hydraulic cylinder 21. There are two hydraulic cylinders 21. The two hydraulic cylinders 21 are fixedly installed at both ends of the upper surface of the equipment base 1. The output end of the hydraulic cylinder 21 is fixedly connected to a fixed plate 22. The two ends of the fixed plate 22 are fixedly connected to pressure plates 23. The bottom of the middle end of the pressure plate 23 is fixedly connected to a rubber pad 24. The outer walls of both ends of the pressure plate 23 are symmetrically fixedly connected to spring bodies 25.

[0026] In this embodiment, the copper-clad laminate is placed on the surface of the workbench 5, and then the hydraulic cylinder 21 is activated. The hydraulic cylinder 21 drives the fixed plate 22 and the pressure plate 23 to move downward through the output end, so that the rubber pad 24 at the bottom of the pressure plate 23 is more stable when pre-pressing the copper-clad laminate, while preventing the phenomenon of warping and reducing the damage caused to it, which can improve the efficiency during pre-pressing.

[0027] Reference Figure 1-3 As shown, the pre-compression structure 4 includes a connecting plate 41. The two ends of the lower surface of the connecting plate 41 are fixedly connected to the top of the support plate 3. A T-shaped groove 42 is provided on the lower surface of the connecting plate 41. A connecting hole 43 is provided on the right outer wall of the connecting plate 41. The connecting hole 43 and the T-shaped groove 42 are connected. A hydraulic cylinder 44 is fixedly installed inside the connecting hole 43. A T-shaped slider 45 is fixedly connected to the output end of the hydraulic cylinder 44. The outer wall of the T-shaped slider 45 is movably connected to the inside of the T-shaped groove 42. A cylinder 46 is fixedly connected to the bottom of the T-shaped slider 45. A movable structure 47 is provided at the output end of the cylinder 46.

[0028] In this embodiment, cylinder 46 is a bidirectional cylinder. The inlet and outlet ends of cylinder 46 are connected to one side of the external reversing valve through compressed air pipes. The other side of the reversing valve is connected to the air inlet of an external air pump through compressed air pipes. In addition, the control terminal of the reversing valve is connected to the control output terminal of the external programmable controller 32 through a cable. Therefore, the programmable controller 32 controls the reversing valve to switch the direction of air supply and exhaust in cylinder 46, thereby realizing the extension and retraction of the push rod of cylinder 46.

[0029] Reference Figure 2 , 5 As shown, the movable structure 47 includes a connecting block 471. The top of the connecting block 471 is fixedly connected to the output end of the cylinder 46. A T-shaped annular groove 472 is provided at the bottom of the connecting block 471. A T-shaped column 473 is movably connected inside the T-shaped annular groove 472. A buffer spring 474 is sleeved on the outer wall of the T-shaped column 473. A U-shaped seat 475 is fixedly connected to the bottom end of the T-shaped column 473. A roller 476 is movably installed inside the U-shaped seat 475.

[0030] In this embodiment, after the copper-clad laminate is placed on the workbench 5, the programmable controller 32 starts the cylinder 46. The cylinder 46 drives the connecting block 471, T-shaped column 473, U-shaped seat 475 and roller 476 to move downward through the output end, so that the bottom of the roller 476 presses against the surface of the copper-clad laminate. Then the programmable controller 32 starts the second hydraulic cylinder 44. The second hydraulic cylinder 44 drives the T-shaped slider 45 to move inside the T-shaped slide groove 42 through the output end, so that the T-shaped slider 45 drives the cylinder 46 and the movable structure 47 to move, so that the roller 476 pre-presses the copper-clad laminate. At the same time, the roller 476 and the U-shaped seat 475 can abut against the copper-clad laminate due to their own gravity, so as to improve the efficiency of pre-pressing the copper-clad laminate.

[0031] Reference Figure 1 , 2 As shown in Figure 4, a symmetrical rectangular groove 31 is provided on the inner side of the support plate 3, a programmable controller 32 is fixedly installed on the outer wall of the support plate 3, and a workbench 5 is fixedly installed on the upper surface of the equipment base 1.

[0032] In this embodiment, hydraulic cylinder 21 is a single-piston hydraulic cylinder. The inlet and outlet of the hydraulic cylinder are connected to one side of an external liquid directional valve via oil pressure pipes, and the other side of the external liquid directional valve is connected to the inlet and outlet of a hydraulic pump via oil pressure pipes. This allows the output of hydraulic cylinder 21 to move up and down. Since there are two hydraulic cylinders 21, the outputs of the two hydraulic cylinders 33 can simultaneously rise or retract in the same direction. Therefore, this will cause a movement between the external liquid directional valve and the hydraulic pump. A flow divider / combiner valve is installed between the pipelines of hydraulic cylinder 21 to ensure that the oil inlet and outlet of hydraulic cylinder 21 are evenly distributed. The inlet and outlet of hydraulic cylinder 21 are connected to the branch inlet and outlet of the external flow divider / combiner valve through oil pressure pipes. The main inlet and outlet of the external flow divider / combiner valve are connected to one side of the external liquid directional valve through oil pressure pipes. Similarly, hydraulic cylinder 44 is designed in the same way as hydraulic cylinder 21. It should be noted that the external liquid directional valve is an externally connected independent design and is an existing technical solution.

[0033] Reference Figure 1 , 2 As shown in Figures 3 and 5, hydraulic cylinder 21 and hydraulic cylinder 44 are electrically connected to programmable controller 32, and programmable controller 32 is electrically connected to cylinder 46.

[0034] In use, the copper-clad laminate is placed on the surface of the workbench 5, and then the hydraulic cylinder 21 is activated. The hydraulic cylinder 21 drives the fixed plate 22 and the pressure plate 23 to move downward through the output end, making the rubber pad 24 at the bottom of the pressure plate 23 more stable when pre-pressing the copper-clad laminate, while preventing edge warping and reducing damage to it, thus improving the efficiency of pre-pressing. Then, the cylinder 46 is activated through the programmable controller 32. The cylinder 46 drives the connecting block 471, T-shaped column 473, U-shaped seat 475 and roller 4 through the output end. 76 moves downward, pressing the bottom of roller 476 onto the surface of the copper-clad laminate. Then, programmable controller 32 activates hydraulic cylinder 2 44. Hydraulic cylinder 2 44 drives T-shaped slider 45 to move inside T-shaped groove 42 through its output end. T-shaped slider 45 drives cylinder 46 and movable structure 47 to move, so that roller 476 pre-presses the copper-clad laminate. At the same time, roller 476 and U-shaped seat 475 can abut against the copper-clad laminate due to their own gravity, thus improving efficiency when pre-pressing the copper-clad laminate.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
