Description

Technical Field

[0001] This invention relates to the field of copper clad laminate coating technology, and more particularly to an intelligent coating apparatus for FCCL production. Background Technology

[0002] Copper clad laminates are generally divided into two main categories: rigid copper clad laminates and flexible copper clad laminates. Three-layer flexible copper clad laminates (FCCLs) are composed of materials such as metal conductor foils and insulating base films. In the current FCCL production process, the metal conductor foils need to be coated, that is, adhesive is sprayed onto the surface of the metal conductor foils. In the current coating process, a coating roller is used to drive the metal conductor foils to rotate in an adhesive tank, so that the adhesive is adsorbed onto the surface of the metal conductor foils to achieve the coating process. During the process of the coating rollers driving the metal conductor foils to rotate in the adhesive tank, the adhesive is prone to adhering to the inside of the metal conductor foils, causing the adhesive to solidify on the inside of the metal conductor foils, making the metal conductor foils unusable and affecting the coating yield.

[0003] Meanwhile, in the existing coating process, the adhesive is subjected to wave motion when the coating roller rotates, causing the adhesive to shake violently and splatter everywhere, which affects the coating yield and makes the equipment difficult to clean and maintain. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies, such as adhesive adhering to the inner side of the metal conductor foil during the rotation of the coating roller in the glue tank, which renders the metal conductor foil unusable, and the fact that the adhesive is subjected to wave motion due to the rotation of the coating roller during the coating process, causing the adhesive to shake violently and splatter everywhere, thus affecting the product yield, this invention provides an intelligent coating device for FCCL production.

[0005] Technical solution: An intelligent FCCL coating device includes a housing and a coating roller; the coating roller is arranged inside the housing; a conveying roller is connected to the left side of the housing; a take-up roller is connected to the right side of the housing; an adhesive inlet is arranged on the right side of the housing; a metal conductor foil is conveyed on the coating roller; it also includes a scraper, a flow stabilizer, and a flow stabilization system; the scraper is arranged inside the housing for cleaning excess adhesive during the coating process; the flow stabilizer is arranged inside the housing for preventing turbulent flow of adhesive; the flow stabilization system is arranged inside the housing for slowing down the flow rate of adhesive.

[0006] To further explain, the scraper has a left cutting edge; the scraper has a right cutting edge; and the scraper has a groove on both the front and rear sides, with the groove located to the right of the left cutting edge.

[0007] To further explain, the flow stabilizer is equipped with several floats, which are connected to the flow stabilizer by ropes.

[0008] To further explain, the flow stabilization system includes a baffle plate; a baffle plate for intercepting adhesive is installed inside the housing, and the baffle plate is located to the left of the feed inlet.

[0009] To further explain, the flow stabilization system also includes a first flow stabilization plate and a second flow stabilization plate; the first flow stabilization plate, used to slow down the flow rate of the adhesive, is fixedly connected to the inner side of the housing; the first flow stabilization plate has several flow holes on its left side; the second flow stabilization plate is installed on the inner side of the housing; the second flow stabilization plate has several adhesive passage holes on its left and right sides.

[0010] To further explain, the current stabilizer is equipped with a brush.

[0011] To further explain, the baffle plate is equipped with scraper grooves.

[0012] To further explain, based on a front-to-back view, the flow hole is oriented with the left side higher than the right.

[0013] Further explanation: It also includes a defoaming roller; a defoaming roller is installed inside the housing; the defoaming roller passes through the right side of the first flow stabilizer plate; the defoaming roller is higher than the liquid level line.

[0014] To further explain, it also includes a glue suction device, an air pump, and a return glue pipe; a glue suction device is installed on the scraper; an air pump is installed on the glue suction device; a return glue pipe is connected to the air pump, and the lower side of the return glue pipe is located to the right of the defoaming roller.

[0015] Compared with the prior art, the present invention has the following advantages: the present invention achieves the cleaning of adhesive carried by the coating roller during the rotation of the coating roller and the transfer of the metal conductor foil by the scraper during the coating process, preventing the adhesive from adhering to the outer surface of the coating roller and the inner side of the metal conductor foil, thereby improving the coating yield.

[0016] During the coating process, the adhesive is divided into upper and lower layers by a flow stabilizer, which slows down the flow rate of the adhesive inside the housing, prevents the adhesive from flowing turbulently inside the housing, and improves the coating yield.

[0017] During the process of the adhesive being fed into the inner side of the housing through the inlet, the flow rate of the adhesive is slowed down by the baffle plate, which further slows down the flow rate of the adhesive inside the housing, prevents the adhesive from flowing turbulently inside the housing, and further ensures the yield of the coating.

[0018] During the process of the coating roller rotating and causing the adhesive to move in waves, the adhesive is divided into three parts by the first flow stabilizer and the second flow stabilizer. At the same time, the flow rate of the adhesive is slowed down by the flow holes and the glue passages opened on the left and right sides of the second flow stabilizer, which prevents the adhesive from flowing turbulently inside the shell and improves the coating yield.

[0019] During the coating process, air bubbles are adsorbed by the bristles on the defoaming roller, causing the bubbles to rotate with the defoaming roller. When the bubbles come into contact with air above the liquid level during the rotation, the bubbles break, thus eliminating the bubbles and preventing them from affecting the coating and causing the adhesive to not be completely adsorbed onto the surface of the metal conductor foil, ensuring the integrity of the coating.

[0020] During the operation of the scraper, the adhesive intercepted on the right blade and groove is sucked up by the adhesive suction device. Then, the sucked adhesive is sent into the inner side of the housing through the return pipe by the air pump, so as to realize the recycling of adhesive and reduce the cost of coating.

Detailed Implementation

[0031] First, it should be noted that in different described embodiments, the same components are given the same reference numerals or the same component names. The disclosure contained throughout this specification can be applied semantically to the same components having the same reference numerals or the same component names. The location descriptions selected in the specification, such as upper, lower, lateral, etc., also refer to the directly described and illustrated figures and are semantically applied to the new location when the location changes.

[0032] Example 1

[0033] like Figures 3-5 As shown, an intelligent FCCL production coating device includes a housing 1 and a coating roller 2; the coating roller 2 is arranged inside the housing 1; a conveying roller is connected to the left side of the housing 1; a take-up roller is connected to the right side of the housing 1; an adhesive inlet is arranged on the right side of the housing 1; and a metal conductor foil 5 is conveyed on the coating roller 2.

[0034] It also includes a scraper 3, a flow stabilizer 4, and a flow stabilization system; the scraper 3 is provided inside the housing 1; during the coating process, the scraper 3 cleans the adhesive carried by the coating roller 2 during rotation and the metal conductor foil 5 during transport, preventing the adhesive from adhering to the outer surface of the coating roller 2 and the inner side of the metal conductor foil 5, thereby improving the coating yield; the flow stabilizer 4 is provided inside the housing 1 to prevent turbulent flow of the adhesive; during the coating process, the flow stabilizer 4 separates the adhesive into upper and lower layers, slowing down the flow rate of the adhesive inside the housing 1, preventing large-scale turbulent flow of the adhesive inside the housing 1, and improving the coating yield; the flow stabilization system is provided inside the housing 1; during the coating process, the flow stabilization system further slows down the flow rate of the adhesive inside the housing 1, preventing large-scale turbulent flow of the adhesive inside the housing 1, and improving the coating yield.

[0035] The scraper 3 is provided with a left cutting edge 3001 and a right cutting edge 3002. A groove 3003 is provided on both the front and rear sides of the scraper 3, with the groove 3003 located to the right of the left cutting edge 3001. During the coating process, the left cutting edge 3001 intercepts the adhesive carried by the coating roller 2 during its rotation, collecting the adhesive in the groove 3003 to prevent it from adhering to the inner side of the uncoated metal conductor foil 5 along with the surface of the coating roller 2. The right cutting edge 3002 intercepts the adhesive carried by the inner side of the coated metal conductor foil 5, preventing it from adhering to the inner side of the coated metal conductor foil 5, thus ensuring the coating yield.

[0036] The flow stabilizer 4 is equipped with several floats 4001, which are connected to the flow stabilizer 4 by a pull rope. During the process of the coating roller 2 rotating to make the adhesive move in waves, the floats 4001 interfere with the movement of water particles in the adhesive, disrupt the water flow structure of the adhesive, reduce wave energy, prevent adhesive from splashing, and improve the coating yield.

[0037] It also includes a first drive component 101 and a second drive component 102; a first drive component 101 is installed on the front and rear sides of the housing 1, and the first drive component 101 is an electric push rod; before coating begins, the first drive component 101 drives the coating roller 2 to move up and down to adjust its position, so as to match the tension generated by the conveying roller and the take-up roller; a second drive component 102 is installed on the front side of the housing 1, and the drive component is fixedly connected to the flow stabilizer 4. The second drive component 102 is a motor; the second drive component 102 drives the flow stabilizer 4 to move slowly.

[0038] Example 2

[0039] Based on Example 1, such as Figures 6-8 As shown, the flow stabilization system includes a baffle plate 201; the baffle plate 201 is installed inside the housing 1 and is located to the left of the feed inlet; during the process of the adhesive entering the inside of the housing 1 through the feed inlet, the baffle plate 201 slows down the flow rate of the adhesive, further slows down the flow rate of the adhesive inside the housing 1, prevents the adhesive from generating large-scale turbulence inside the housing 1, and ensures the coating yield.

[0040] The flow stabilization system also includes a first flow stabilizing plate 202 and a second flow stabilizing plate 203; the first flow stabilizing plate 202 is fixedly connected to the inner side of the housing 1; a plurality of flow holes 20201 are opened on the left side of the first flow stabilizing plate 202; the second flow stabilizing plate 203 is installed on the inner side of the housing 1; a plurality of glue passage holes are opened on the left and right sides of the second flow stabilizing plate 203; during the process of the coating roller 2 rotating to make the adhesive move in waves, the adhesive on the right side of the first flow stabilizing plate 202, the adhesive between the first flow stabilizing plate 202 and the second flow stabilizing plate 203, and the adhesive on the right side of the second flow stabilizing plate 203 are separated into three parts by the first flow stabilizing plate 202 and the second flow stabilizing plate 203. At the same time, the flow velocity of the adhesive is slowed down by the flow holes 20201 and the glue passage holes opened on the left and right sides of the second flow stabilizing plate 203, preventing the adhesive from generating large-scale turbulence inside the housing 1 and improving the coating yield.

[0041] The flow stabilizer 4 is equipped with a brush 4002. During the rotation of the coating roller 2, air is injected into the adhesive. The air bubbles generated on the surface of the adhesive are captured by the brush 4002 as the flow stabilizer 4 moves from left to right. The air bubbles are adsorbed onto the brush bristles and move synchronously from left to right, thus capturing the air bubbles on the left and below the coating roller 2. This prevents the air bubbles from floating on the surface of the adhesive and ensures the purity of the adhesive.

[0042] The baffle plate 201 is provided with a scraper groove 20101; during the process of the flow stabilizer 4 conveying from left to right, the air bubbles adsorbed on the brush 4002 are scraped off by the scraper groove 20101. Driven by the air inside the air bubbles, the air bubbles float upward along the baffle plate 201 to the top of the inner side of the first flow stabilizer plate 202, thereby collecting the air bubbles adsorbed on the brush 4002, preventing the air bubbles from flowing back, and ensuring the collection effect of the air bubbles.

[0043] With a front-to-back view as a reference, the flow hole 20201 is oriented with the left side higher than the right side. During the rotation of the coating roller 2, air is injected into the adhesive, and bubbles are generated on the surface of the adhesive. Since the adhesive liquid level on the left side of the flow hole 20201 is higher than that on the right side, the adhesive on the left side of the flow hole 20201 flows to the right side of the flow hole 20201 through the left-high-right-low shape of the flow hole 20201, causing the bubbles to concentrate at the top inner side of the first flow stabilizer plate 202. This achieves the collection of bubbles on the left side of the flow hole 20201, further enhancing the collection of bubbles on the surface of the adhesive and ensuring the purity of the adhesive.

[0044] It also includes a defoaming roller 204; a defoaming roller 204 is installed inside the housing 1; the defoaming roller 204 passes through the right side of the first flow stabilizer 202; as Figure 6 As shown, the defoaming roller 204 is above the liquid level 1001. During the coating process, the bristles on the defoaming roller 204 adsorb air bubbles, causing the air bubbles to rotate clockwise synchronously with the defoaming roller 204. When the air bubbles come into contact with the air above the liquid level 1001 during the rotation, the air bubbles break, thus eliminating the air bubbles and preventing them from affecting the coating process. This would prevent the adhesive from being completely adsorbed onto the surface of the metal conductor foil 5, ensuring the integrity of the coating.

[0045] Example 3

[0046] Based on Example 2, such as Figure 1 , Figure 2 and Figure 9As shown, it also includes a glue suction device 301, an air pump 302, and a return glue pipe 303; the glue suction device 301 is installed on the scraper 3; the air pump 302 is installed on the glue suction device 301; the return glue pipe 303 is connected to the air pump 302, and the lower side of the return glue pipe 303 is located to the right of the defoaming roller 204; during the operation of the scraper 3, the glue suction device 301 sucks up the adhesive intercepted on the right blade surface 3002 and the groove 3003, and then the air pump 302 passes the sucked adhesive through the return glue pipe 303 into the inner side of the housing 1, realizing the recycling of adhesive and reducing the cost of coating.
