Technical Field
[0001] This invention relates to the field of copper clad laminate processing equipment, and specifically to a copper clad laminate lamination and composite processing equipment. Background Technology
[0002] Copper clad laminate (CCL) is a core material for manufacturing printed circuit boards (PCBs). It typically consists of a substrate, copper foil, and adhesive, and the layers are bonded together using a high-temperature, high-pressure lamination process. In the actual lamination process, the stacked substrate and copper foil are placed between the upper and lower hot press plates of a hot press. Under heating and pressure, the adhesive melts, flows, and cures, thus achieving interlayer bonding.
[0003] However, existing copper clad laminate (CCL) lamination processes commonly suffer from a series of defects caused by adhesive overflow and insufficient venting. Specifically, during hot pressing, under high temperature and pressure, some of the adhesive between the substrate and the copper foil overflows from the side of the CCL. This overflowing adhesive easily adheres to the surface of the hot press plate and the supporting parts of the processing table. When a lamination cycle ends and the hot press plate is removed from the product, the high-temperature adhesive adhering to the hot press plate has not yet fully cured and has a certain degree of fluidity. It may flow or drip along the surface of the hot press plate to the working area that was originally in contact with the next batch of upper layer material to be pressed. If this part of the adhesive gradually cools and solidifies after flowing, it will form hard residue. During the next lamination, this cured residue will be trapped between the hot press plate and the upper layer material. Under high pressure, this causes uneven stress on the copper foil or substrate of the upper layer material, resulting in extrusion deformation, indentation, or even damage. If the adhesive that adheres to and flows into the area has not yet cured, it will remelt and bond with the surface of the upper material during subsequent hot pressing, thus forming an unintended additional adhesive film layer on the surface of the upper material, which seriously affects the appearance, thickness uniformity and subsequent processing performance of the copper clad laminate.
[0004] Meanwhile, during the lamination process, as the adhesive flows and fills the space between the substrate and the copper foil, air bubbles are often trapped or generated within it. Due to the relatively closed structure formed by the copper foil and the substrate, and the fact that the adhesive remains highly viscous even at high temperatures, these air bubbles are difficult to effectively escape from the interlayer. These trapped air bubbles form voids after the adhesive cures, resulting in porosity within the copper-clad laminate. This weakens the product's dielectric properties, interlayer bonding strength, and reliability, becoming a significant hidden danger affecting the quality of the copper-clad laminate. Summary of the Invention
[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a copper clad laminate lamination and composite processing equipment, so as to effectively avoid product defects caused by adhesive overflow, reduce interlayer air bubbles and voids, and improve the lamination quality and yield of copper clad laminates.
[0006] The objective of this invention can be achieved through the following technical solutions: A copper clad laminate lamination processing equipment includes a support frame and a base plate, and the equipment further includes: A hot press plate is provided, and a hydraulic cylinder is installed on the bracket. The output end of the hydraulic cylinder is provided with a connecting rod, and the end of the connecting rod is provided with a hot press plate. The defoaming component is mounted on the periphery of the connecting rod, and a winding mechanism that drives the defoaming component to move up and down is mounted on the bracket.

The cleaning assembly has four sets and is slidably installed in the four sets of sliding grooves. Initially, the four sets of cleaning assemblies are located at the four corners of the copper-clad board to be laminated. The cleaning assembly includes an upper scraper and a side scraper for cleaning the adhesive. The driving assembly includes four sets of driving assemblies installed on the defoaming assembly and the base plate. The defoaming assembly moves downward to drive the cleaning assembly to clean the adhesive on the bottom of the hot press plate and the side of the copper clad laminate.
[0007] As a further embodiment of the present invention: the cleaning assembly further includes a sliding plate, a mounting plate, and an extrusion block. The sliding plate is slidably installed in the slide groove, the mounting plate is fixed on the top of the sliding plate, the extrusion block is slidably installed on the mounting plate, a pneumatic telescopic rod is connected between the mounting plate and the extrusion block, the pneumatic telescopic rod is connected to an external pneumatic adjustment mechanism, the top of the extrusion block is wedge-shaped, the upper scraper is obliquely slidably installed on the top of the extrusion block, and a side scraper is slidably installed on the side of the extrusion block. When the upper scraper and the side scraper move, they respectively clean the adhesive on the bottom of the hot press plate and the side of the copper-clad laminate.
[0008] As a further embodiment of the present invention: the top of the upper scraper is provided with an upper scraper, the two sides of the upper scraper are symmetrically provided with side scrapers one and two sides of the side scraper, and the bottom of the side scraper is provided with a lower scraper. The upper scraper elastically abuts against the bottom of the hot press plate, the two side scrapers one and two side scrapers elastically abut against the side of the copper-clad laminate, and the lower scraper abuts against the top of the bottom plate.
[0009] As a further embodiment of the present invention: the bottom of the upper scraper is provided with a notch, the notch is wedge-shaped, a slider is provided at the notch, an inclined groove is provided at the top of the extrusion block, the slider and the inclined groove are slidably engaged, an elastic element two is connected between the slider and the inclined groove, a support plate is provided on the side of the side scraper, an expansion groove is provided in the extrusion block, the support plate and the expansion groove are slidably engaged, an elastic element three is connected between the support plate and the expansion groove, and the side scraper, the second side scraper and the lower scraper are all located in the notch.
[0010] As a further embodiment of the present invention: the driving assembly includes a connecting plate, a pressure rod and a fixed cylinder. The connecting plate is connected to the defoaming assembly. The pressure rod is fixed on the connecting plate and kept vertical. The fixed cylinder is fixed on the base plate. An air outlet pipe is provided on one side of the fixed cylinder. A push plate is provided on the mounting plate. The end of the air outlet pipe abuts against the push plate. A piston is slidably installed inside the fixed cylinder. An elastic element is connected between the piston and the bottom of the inner cavity of the fixed cylinder.
[0011] As a further aspect of the present invention: four sets of mounting slots are provided on the base plate, the mounting slots are connected to the sliding grooves, and an elastic element is connected between the mounting slots and the sliding plate in the sliding grooves.
[0012] As a further aspect of the present invention: the defoaming component includes a central hammer and an outer frame hammer. The central hammer is slidably mounted on the periphery of the connecting rod. The outer frame hammer is provided in several groups, and the size of the several groups of outer frame hammers gradually increases from the inside to the outside. The innermost outer frame hammer is slidably sleeved around the central hammer, and the several outer frame hammers on the outside are layered together from the inside to the outside.
[0013] As a further embodiment of the present invention: a group of connecting plates, pressure rods and fixing cylinders in a group of driving components are provided with several groups of connecting plates respectively fixed around the center hammer and several outer frame hammers, the connecting plates are staggered, and the bottom of the outer frame hammer is provided with an embedding groove to accommodate the connecting plates.
[0014] The beneficial effects of this invention are: (1) By cooperating with the cleaning component and the driving component, when the defoaming component falls, the pressure rod compresses the air in the fixed cylinder to form a high-speed airflow, which pushes the slide plate to move along the slide groove. This drives the upper scraper and the side scraper to scrape the bottom of the hot press plate, the side of the copper-clad laminate and the top of the base plate, respectively. This achieves synchronous automatic cleaning of the overflow adhesive during the hot pressing process, avoiding the residue of adhesive from causing the upper material to be squeezed and deformed, producing indentations or forming an additional adhesive film layer during the next hot pressing, thus greatly improving the product yield and surface quality.
[0015] (2) By setting up a defoaming component, the present invention uses the center hammer and the outer frame hammer to fall and strike the hot press plate in sequence during the hot pressing process, which can squeeze out the bubbles between the copper clad laminate layers from the inside to the outside. At the same time, the repeated impact vibration helps the bubbles to float and overflow, thereby effectively reducing the defects of interlayer bubble voids and improving the dielectric properties and interlayer bonding reliability of the copper clad laminate.
[0016] (3) In this invention, the upper scraper and the side scraper of the cleaning component are kept in elastic contact with the bottom of the hot press plate and the side of the copper-clad laminate by pneumatic telescopic rod and elastic component. This can not only adapt to the thickness change during the hot pressing process, but also assist in positioning the stacked materials while scraping off the adhesive, preventing side slippage. Combined with the elastic component in the chute, the cleaning component can perform multiple reciprocating cleanings under the action of airflow and rebound. Under the action of intermittent airflow generated by the sequential falling of the center hammer and the multi-layer outer frame hammer, multiple thorough cleanings are achieved within a single lamination cycle. Even during the upward movement of the hot press plate, the cleaning continues, which significantly improves the effect of removing excess adhesive. Attached Figure Description

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0021] like Figure 1-8 As shown, a copper clad laminate lamination processing equipment includes a support 1 and a base plate 2. The equipment also includes: A hot press plate 4 and a support 1 are mounted with a hydraulic cylinder 3. The output end of the hydraulic cylinder 3 is provided with a connecting rod 31, and the end of the connecting rod 31 is provided with a hot press plate 4. Defoaming component 5, defoaming component 5 is installed on the periphery of connecting rod 31, and a winding mechanism 6 is installed on bracket 1 to drive defoaming component 5 to move up and down; The cleaning component 7 has four sets of sliding grooves 21 on the base plate 2. The four sets of sliding grooves 21 are located around the copper plate to be laminated. The cleaning component 7 has four sets and is slidably installed in the four sets of sliding grooves 21 respectively. Initially, the four sets of cleaning components 7 are located at the four corners of the copper plate to be laminated. The cleaning component 7 includes an upper scraper 75 and a side scraper 76 for cleaning the adhesive. Four sets of drive assemblies 8 are installed on the drive assembly 8, the defoaming assembly 5 and the base plate 2. The drive assembly 8 drives the cleaning assembly 7 to clean the adhesive on the bottom of the hot press plate 4 and the side of the copper clad laminate by moving the defoaming assembly 5 downward.
[0022] In one embodiment, the winding mechanism 6 uses a winding roller and a connecting rope to connect to the defoaming component 5, so that the defoaming component 5 can fall freely during unwinding and move upward during winding. The winding mechanism 6 can also be other components that can achieve the above-mentioned movements.
[0023] In practical application, the stacked substrate and copper foil are placed on the base plate 2. Simultaneously, the four cleaning components 7 are adjusted to the four corners of the stacked substrate and copper foil. Then, the hydraulic cylinder 3 is activated, causing the connecting rod 31 to move the hot press plate 4 downwards, pressing the stacked substrate and copper foil, thus completing the lamination of the copper-clad laminate. During the hot pressing process, the winding mechanism 6 causes the defoaming component 5 to fall freely. The downward movement of the defoaming component 5 causes the four driving components 8 to drive the four cleaning components 7 to clean the bottom of the hot press plate 4, the top of the base plate 2, and the sides of the copper-clad laminate. This effectively removes any excess adhesive during the hot pressing process, preventing residual adhesive on the bottom of the hot press plate 4, the top of the base plate 2, and the sides of the copper-clad laminate. This also effectively prevents the stacked upper material from being deformed by pressure during the next hot pressing, resulting in indentations, damage, or additional adhesive layers, thereby improving the hot pressing quality of each copper-clad laminate. In addition, when the defoaming component 5 falls freely and collides with the top of the hot press plate 4, the defoaming component 5 can further enhance the hot pressure and squeeze out the air bubbles between the materials, thereby effectively preventing voids from appearing in the copper clad laminate and ensuring the performance and quality of the copper clad laminate.
[0024] Furthermore, the cleaning component 7 also includes a slide plate 71, a mounting plate 72, and an extrusion block 74. The slide plate 71 is slidably installed in the slide groove 21, the mounting plate 72 is fixed to the top of the slide plate 71, and the extrusion block 74 is slidably installed on the mounting plate 72. A pneumatic telescopic rod 73 is connected between the mounting plate 72 and the extrusion block 74. The pneumatic telescopic rod 73 is connected to an external pneumatic adjustment mechanism. The top of the extrusion block 74 is wedge-shaped. An upper scraper 75 is obliquely slidably installed on the top of the extrusion block 74. A side scraper 76 is slidably installed on the side of the extrusion block 74. When the upper scraper 75 and the side scraper 76 move, they respectively clean the adhesive on the bottom of the hot press plate 4 and the side of the copper-clad laminate.
[0025] The upper scraper 75 is provided with an upper scraper 751 at the top, and side scrapers 751 are symmetrically provided on both sides of the upper scraper 75. Side scrapers 76 are symmetrically provided with side scrapers 761 on both sides, and a lower scraper 762 is provided at the bottom of the side scraper 76. The upper scraper 751 elastically abuts against the bottom of the hot press plate 4, and both side scrapers 752 and side scrapers 761 elastically abut against the side of the copper-clad laminate. The lower scraper 762 abuts against the top of the base plate 2.
[0026] The upper scraper 75 has a notch 753 at its bottom, which is wedge-shaped. A slider 754 is provided at the notch 753. A groove 741 is provided at the top of the extrusion block 74. The slider 754 and the groove 741 are slidably engaged. An elastic element 742 is connected between the slider 754 and the groove 741. The side scraper 76 has a support plate 763 on its side. A telescopic groove is provided inside the extrusion block 74. The support plate 763 and the telescopic groove are slidably engaged. An elastic element 764 is connected between the support plate 763 and the telescopic groove. The side scraper 76, the second side scraper 761, and the lower scraper 762 are all located inside the notch 753.
[0027] In practical application, after the stacked substrate and copper foil are placed on the base plate 2, the length of the pneumatic telescopic rod 73 is adjusted by the external pneumatic adjustment mechanism. The pneumatic telescopic rod 73 pushes the extrusion block 74 toward the side of the stacked substrate and copper foil. Then, the pneumatic telescopic rod 73 is brought to a stable state. At this time, the pneumatic telescopic rod 73 acts as a spring, so that the upper scraper 75 and the side scraper 76 elastically abut against the side of the stacked substrate and copper foil. This can also clamp the stacked substrate and copper foil, ensuring that the stacked substrate and copper foil are placed in the correct position, and at the same time, preventing the stacked substrate and copper foil from slipping during hot pressing, thus ensuring the quality of hot pressing. During hot pressing, the downward movement of the hot press plate 4 will squeeze the upper scraper 75, causing the upper scraper 75 to move downward. Due to the inclined sliding cooperation between the upper scraper 75 and the extrusion block 74, the extrusion block 74 moves towards the pneumatic telescopic rod 73 and squeezes the pneumatic telescopic rod 73. With the cooperation of the second elastic element 742 and the third elastic element 764, the upper scraper 75 and the side scraper 76 are always elastically resisted against the sides of the stacked substrate and copper foil. When the defoaming component 5 moves downward and activates the drive component 8, the drive component 8 will push the slide plate 71 to slide along the slide groove 21. During the sliding of the slide plate 71, the upper scraper 751... The adhesive on the bottom of the hot press plate 4 will be scraped off. The side scraper 1 752 and the side scraper 2 761 work together to scrape off all the adhesive on the sides of the stacked substrate and copper foil. The bottom scraper 762 will scrape up the adhesive on the base plate 2. The scraped adhesive is away from the bottom of the hot press plate 4, the top of the base plate 2 and the sides of the copper clad laminate, thus effectively avoiding the presence of adhesive residue on the bottom of the hot press plate 4 and the top of the base plate 2 after hot pressing. This effectively prevents the stacked upper material from being squeezed and deformed during the next hot pressing, resulting in indentations, damage or additional adhesive film layers, thereby improving the hot pressing quality of the copper clad laminate each time.
[0028] Furthermore, the drive assembly 8 includes a connecting plate 81, a pressure rod 82, and a fixed cylinder 83. The connecting plate 81 is connected to the defoaming assembly 5. The pressure rod 82 is fixed on the connecting plate 81 and kept vertical. The fixed cylinder 83 is fixed on the base plate 2. An air outlet pipe 831 is provided on one side of the fixed cylinder 83. A push plate 721 is provided on the mounting plate 72. The end of the air outlet pipe 831 abuts against the push plate 721. A piston 832 is slidably installed inside the fixed cylinder 83. An elastic element 833 is connected between the piston 832 and the bottom of the inner cavity of the fixed cylinder 83.
[0029] Four sets of mounting slots 22 are provided on the base plate 2. The mounting slots 22 are connected to the slide 21. An elastic element 23 is connected between the mounting slots 22 and the slide plate 71 in the slide 21.
[0030] In practical application, when the defoaming component 5 falls downwards, the connecting plate 81 will drive the pressure rod 82 to move downwards. The pressure rod 82 will squeeze the piston 832 in the fixed cylinder 83. After the piston 832 moves downwards, it will squeeze the air in the fixed cylinder 83, causing the air to be compressed and ejected from the air outlet pipe 831. The ejected high-speed airflow will push the push plate 721, causing the push plate 721 to drive the slide plate 71 to slide along the slide groove 21, thereby moving the upper scraper 75 and the side scraper 76 to clean the adhesive. During the movement of the slide plate 71, the elastic element 23 is stretched. When the elastic element 23 is stretched to its limit, the upper scraper 75 and the side scraper 76 have moved completely along the side of the copper-clad laminate once. At the same time, due to the length limitation of the slide groove 21, after the upper scraper 75 and the side scraper 76 are pushed and moved once, they still elastically resist the side of the copper-clad laminate. At this time, under the rebound action of the elastic element 23, the upper scraper 75 and the side scraper 76 move towards their initial position. This can clean the bottom of the hot press plate 4, the top of the base plate 2, and the side of the copper-clad laminate again, thereby improving the cleaning effect and further avoiding the residue of adhesive on the bottom of the hot press plate 4 and the top of the base plate 2 after the hot press is completed. This further effectively avoids the upper layer material being squeezed and deformed during the next hot press, resulting in indentations, damage, or the appearance of an additional adhesive film layer, thereby improving the hot press quality of the copper-clad laminate each time.
[0031] Furthermore, the defoaming component 5 includes a central hammer 51 and an outer frame hammer 52. The central hammer 51 is slidably mounted on the periphery of the connecting rod 31. The outer frame hammer 52 is provided in several groups, and the size of the several groups of outer frame hammers 52 gradually increases from the inside to the outside. The innermost outer frame hammer 52 is slidably sleeved on the periphery of the central hammer 51, and the several outer frame hammers 52 on the outside are layered together from the inside to the outside.
[0032] In one embodiment, the central hammer 51 and several outer frame hammers 52 each correspond to a set of winding mechanisms 6, so that the free fall and upward movement of the central hammer 51 and several outer frame hammers 52 are carried out independently.
[0033] In practical application, when the hot press plate 4 presses the stacked substrate and copper foil together, the winding mechanism 6 first causes the central hammer 51 to fall freely, and then causes several outer frame hammers 52 to fall freely from the inside out. This allows the hot press plate 4 to be struck sequentially from the inside out, thereby squeezing out the air bubbles inside the copper-clad laminate from the inside out, effectively preventing voids inside the copper-clad laminate and ensuring its performance and quality. At the same time, this repeated, intermittent vibration can help the air bubbles escape, thereby further preventing voids inside the copper-clad laminate. In addition, when the center hammer 51 and the outer frame hammer 52 fall freely and strike the hot press plate 4, they can shake off the adhesive adhering to the bottom of the hot press plate 4. Combined with the cleaning of the upper scraper 75 and the side scraper 76, the cleaning effect can be further improved.
[0034] Furthermore, the connecting plate 81, pressure rod 82 and fixing cylinder 83 in a set of drive components 8 are provided with several sets. Several sets of connecting plates 81 are respectively fixed to the periphery of the central hammer 51 and several outer frame hammers 52. The several connecting plates 81 are staggered. The bottom of the outer frame hammer 52 is provided with an embedding groove 521 to accommodate the connecting plate 81.
[0035] In practical application, this embodiment uses several fixed cylinders 83 and pressure rods 82. When the central hammer 51 and several outer frame hammers 52 fall freely in sequence, the air in the fixed cylinders 83 is intermittently ejected at high speed. This, combined with the elastic element 23, causes the slide plate 71 to return to its original position. This allows the cleaning component 7 to repeatedly clean the bottom of the hot press plate 4, the top of the base plate 2, and the sides of the copper-clad laminate during a single hot pressing process, further improving the cleaning effect. At the same time, the interval between the falling of the outer frame hammers 52 can be controlled so that during the upward movement of the hot press plate 4 after hot pressing, the outer frame hammers 52 continue to fall freely, ensuring that the hot press plate 4 is cleaned during the upward movement, further improving the cleaning effect.
[0036] Working principle: First, the stacked substrate and copper foil are placed on the base plate 2, and the four cleaning components 7 are moved to the four corners of the copper-clad laminate. The pneumatic telescopic rod 73 is adjusted by the external pneumatic adjustment mechanism, causing the extrusion block 74 to move forward. This allows the upper scraper 751, side scraper one 752, side scraper two 761, and lower scraper 762 to elastically abut against the bottom of the hot press plate 4, the side of the copper-clad laminate, and the top of the base plate 2, respectively, clamping and positioning the stacked material. The hydraulic cylinder 3 is activated, and the connecting rod 31 drives the hot press plate 4 downwards for lamination. During lamination, the winding mechanism 6 first releases the central hammer 51 for free fall, followed by the sequential release of several outer frame hammers 52 from the inside out. The central hammer 51 and the outer frame hammers 52 strike the hot press plate 4 in sequence, squeezing and vibrating to expel interlayer air bubbles from the inside out. When the central hammer 51 and each outer frame hammer 52 move downwards, they drive the corresponding pressure rods 82 downwards via their respective connecting plates 81. The pressure rods 82 push the pistons 832 inside the fixed cylinder 83 to compress air. The high-pressure airflow is ejected from the air outlet pipe 831, pushing the push plate 721 and causing the slide plate 71 to slide along the slide groove 21. At the same time, the elastic element 1 23 is stretched, thereby driving the upper scraper 75 and the side scraper 76 to move. The upper scraper 751 scrapes off the adhesive at the bottom of the hot press plate 4, the side scraper 1 752 and the side scraper 2 761 scrape off the adhesive on the side of the copper-clad laminate in turn, and the lower scraper 762 scrapes off the adhesive on the top of the bottom plate 2. When the slide plate 71 moves to its limit position, it moves in the opposite direction under the rebound action of the elastic element 1 23, realizing reciprocating cleaning. As the central hammer 51 and multiple outer frame hammers 52 fall in sequence, multiple sets of pressure rods 82 compress multiple sets of fixed cylinders 83 in sequence, generating multiple intermittent air jets, driving the cleaning component 7 to perform multiple reciprocating scrapings, and can continue cleaning during the upward movement of the hot pressure plate 4, thereby completely removing the excess adhesive.
