Anti-deviation HDI circuit board multi-layer pressing device

Abstract

This invention discloses an anti-displacement HDI circuit board multilayer lamination processing device, including a lamination cabinet, a base frame, and a lamination assembly. The lamination assembly is used to laminate prepreg, copper foil, and core board. This invention features a wedge-shaped block on the side of the second L-shaped plate facing the center of the limiting rod, which is engaged in an annular groove, ensuring that the second lamination plate always maintains a fixed state on the copper foil, prepreg, and core board. The first, second, and third lamination plates work together to laminate the copper foil, prepreg, and core board, preventing displacement during lamination. It also eliminates the need for additional fixing devices, solving the problem of uneven surfaces caused by the prepreg rebounding after being laid flat in flat equipment, resulting in poor adhesion between the prepreg and the copper foil and core board, leading to slippage, displacement, and delamination during subsequent lamination.

Description

Technical Field

[0001] This invention belongs to the field of circuit board processing, and specifically relates to a multilayer lamination processing device for HDI circuit boards that prevents misalignment. Background Technology

[0002] In existing technologies, during the processing of multilayer circuit boards, copper foil, prepreg, and core board are stacked manually or by machine. Due to the plasticity of the prepreg itself, local bulges or wavy shapes may occur during transportation and storage. After the flattening equipment flattens and smooths the prepreg, there is no fixed measure to fix it in place, which causes the deformed part of the prepreg to spring back again, and the surface still has unevenness. This results in poor adhesion between the prepreg and the copper foil and core board, leading to slippage, misalignment, and delamination in subsequent lamination, resulting in quality problems.

[0044] The right-side limiting unit includes a second electric push rod 408, a fourth fixing plate 409, a fixing cylinder 414, a trapezoidal block 415, a fixing ring 416, a second L-shaped plate 417, a wedge block 418, and an elastic telescopic rod 419; two symmetrically arranged second electric push rods 408 are fixedly connected to the upper right side of the second pressing plate 407; the telescopic ends of the two second electric push rods 408 are jointly fixedly connected to the fourth fixing plate 409; two symmetrically arranged fixing cylinders 414 are fixedly connected to the lower side of the fourth fixing plate 409; four trapezoidal blocks 415 are equidistantly fixed around the lower circumference of the fixing cylinders 414; the upper right side of the second pressing plate 407 Two symmetrical fixing rings 416 are fixedly connected, each located below a fixing cylinder 414. Four elastic telescopic rods 419 are fixedly connected at equal intervals around the inner wall of the fixing rings 416. A second L-shaped plate 417 is fixedly connected to the telescopic end of each of the four elastic telescopic rods 419. A wedge block 418 is fixedly connected to the side of each of the four second L-shaped plates 417 facing the center of the limiting rod 403, and all four wedge blocks 418 are in contact with the limiting rod 403. A wedge block 418 is fixedly connected to the upper side of each of the four second L-shaped plates 417, and each of the four wedge blocks 418 is in contact with a trapezoidal block 415.

[0045] During operation, the second electric push rod 408 is retracted, causing the fourth fixed plate 409, fixed cylinder 414, and trapezoidal block 415 to move downwards. This causes the trapezoidal block 415 to press against the wedge block 418 on the upper side of the second L-shaped plate 417, thereby moving the second L-shaped plate 417 towards the inner wall of the fixed ring 416. This compresses the elastic telescopic rod 419, causing the wedge block 418 on the side of the second L-shaped plate 417 facing the center of the limiting rod 403 to separate from the limiting rod 403. Then, the second pressing plate 407 is removed from the limiting rod 403 through the existing clamping and lifting mechanism, separating the second pressing plate 407 from the first pressing plate 401. Next, the second drive motor 314 is started, and the output shaft of the second drive motor 314 drives the transmission column of the flat gear 315. Gear 313 rotates, driving the splined shaft 309 to rotate the thin pressure plate 310, making it parallel to the side of the first pressing plate 401. This prevents the thin pressure plate 310 from obstructing the copper foil laying. The copper foil is then laid flat on the first pressing plate 401 using existing laying equipment. Next, a prepreg is laid flat on the copper foil. Due to the prepreg's inherent plasticity, it may bulge or waviness during transportation and storage. The laying equipment, after smoothing the prepreg, lacks proper fixing, causing the deformed prepreg to spring back, resulting in surface unevenness. This leads to poor adhesion between the prepreg, copper foil, and core board, causing delamination during subsequent pressing and resulting in quality problems. When the prepreg is laid flat and smoothed, the second drive motors 314 at any two diagonal positions of the first pressing plate 401 are reversed, causing the spline shaft 309 to drive the thin pressure plate 310 to rotate to its initial position. Then, the first electric push rod 311 is extended to push the third fixing plate 312 downward, causing the spline shaft 309 to drive the thin pressure plate 310 downward until the thin pressure plate 310 presses onto the prepreg. Thus, the two thin pressure plates 310 press down on the two corners of the prepreg, fixing the flattened prepreg and keeping it in close contact with the copper foil. Then, the core board is placed on the prepreg manually or using existing feeding equipment. Finally, the second drive motors 314 at the other two diagonal positions of the first pressing plate 401 are reversed. The spline shaft 309 drives the thin pressure plate 310 to rotate to the upper corner of the core plate. Then, the first electric push rod 311 is controlled to extend and push the third fixing plate 312 downward, so that the thin pressure plate 310 presses onto the core plate. The core plate presses down on the prepreg and fixes it. Then, the second drive motor 314 below the thin pressure plate 310 pressing on the prepreg is started, so that the thin pressure plate 310 separates from the prepreg. At this time, the two thin pressure plates 310 pressing on the core plate press down on the core plate, thereby fixing the prepreg. This cycle is repeated. Each time, the two diagonally opposite thin pressure plates 310 of the first pressing plate 401 cooperate to fix the prepreg. Then, another prepreg is laid flat on the core plate. Finally, another copper foil is laid flat on the top prepreg.At this point, the thin pressure plates 310 at two diagonal positions of the first pressing plate 401 press onto the copper foil, fixing the laminated prepreg and core board;

[0046] Then, using the existing clamping and lifting mechanism, the second pressing plate 407 is placed back onto the four limiting rods 403. Next, the two third electric push rods 410 are controlled to retract, causing the T-shaped plate 411 to move the third pressing plate 412 downwards, pressing the middle of the copper foil with the third pressing plate 412. This fixes the prepreg and core board under the copper foil, preventing them from shifting. At this point, there is a gap between the second pressing plate 407 and the thin pressing plate 310. The second drive motor 314 is then started, aligning the four thin pressing plates 310 with one side of the first pressing plate 401, preventing the second pressing plate 407 from being blocked from contacting the uppermost copper foil. Then, the lifting mechanism drives the third... The second pressing plate 407 moves downward, making its lower side flush with the lower side of the third pressing plate 412. As the second pressing plate 407 moves downward, it pushes the ring 404 downward, compressing the return spring 405. Then, the second electric push rod 408 is extended and reset, causing the fourth fixing plate 409 to drive the fixing cylinder 414 and trapezoidal block 415 to rise and reset. Then, the elastic telescopic rod 419 releases its elastic force, causing the second L-shaped plate 417 to drive the wedge block 418 to reset. The wedge block 418 on the side of the second L-shaped plate 417 facing the center of the limiting rod 403 is stuck in the annular inclined groove 002, thus keeping the second pressing plate 407 in a fixed state for the copper foil, prepreg, and core board.

[0047] By controlling the extension and retraction of the hydraulic cylinder 209, the pressure block 210 is aligned with the limiting groove formed between the two adjacent limiting blocks 406. Then, the translation unit drives the support plate 304 and the carrying plate 305 to move rearward until the front of the first pressing plate 401 is behind the electric clamp 207. Next, the two lifting mechanisms drive the first fixed plate 203, the second electric slide rail 204, the second electric slider 205, the second fixed plate 206, and the electric clamp 207 to move downward, so that the electric clamp 207 is aligned with the second pressing plate 407. Then, the two second electric sliders 205 are controlled to simultaneously move on the two second electric slide rails 206. 04. Slide the upper part of the slide to the rearward direction, so that the electric clamp 207 clamps the second pressing plate 407. Then, the first drive motor 306 starts. With the reference from right to left, the output shaft of the first drive motor 306 rotates 90 degrees clockwise, so that the first L-shaped plate 307 drives the positioning plate 308 to rotate, thereby preventing the positioning plate 308 from blocking the movement of the first pressing plate 401. Then, control the two second electric sliders 205 to continue sliding to the rearward direction, thereby pushing the first pressing plate 401 to move to the rearward direction, so that the pressing block 210 is located in the limiting groove formed between the two adjacent limiting blocks 406, so that the second insertion port 402 is inserted into the first insertion port 401. Inside port 212, the first insertion port 212 is connected to an external power source via a spring wire. The first insertion port 212 can move synchronously with the extension and retraction of the hydraulic cylinder 209. Then, the electric clamp 207 releases the second pressing plate 407, the second electric slider 205 slides back to its original position, the first electric slider 202 slides upward to its original position on the first electric slide rail 201, and the third electric slider 303 slides back to its original position. Then, another first pressing plate 401 is placed on the carrier plate 305, and the above operation is repeated to perform the pre-pressing layering work, which cooperates with another second pressing plate 407 for fixation. The sliding of the first electric slider 202 is controlled by the control of the first electric slider 202. The electric clamp 207 is positioned at different heights, allowing the first pressing plate 401 and the second pressing plate 407 to be placed into different pressing units. This enables multiple pressing units to perform pressing work simultaneously, improving work efficiency. The first pressing plate 401, the second pressing plate 407, and the third pressing plate 412 are all equipped with built-in heating systems. The second pressing plate 407 maintains temperature synchronization with the third pressing plate 412 through the data connection line 413, ensuring pressing quality. By controlling the extension of the hydraulic cylinder 209, the first pressing plate 401, the second pressing plate 407, and the third pressing plate 412 work together to press the copper foil, prepreg, and core board.
