Description
Technical Field
[0001] This utility model belongs to the field of copper clad laminate production technology, specifically, it relates to an adhesive application device suitable for copper clad laminate production. Background Technology
[0002] Copper-clad laminate is a plate-shaped material made by impregnating electronic fiberglass cloth or other reinforcing materials with resin glue, covering one or both sides with copper foil, and then hot-pressing it. It is also called copper-clad board. Various types and functions of printed circuit boards are made by selectively processing, etching, drilling, and copper plating on copper-clad boards to create different printed circuits.
[0003] In current copper clad laminate processing, the substrate is usually directly sent to the glue tank for impregnation. Since the surface of the substrate may be covered with dust and impurities, impregnation in the glue tank can easily contaminate the glue, shorten the glue's shelf life, and increase costs. Furthermore, since drying needs to be carried out in an oven, the substrate surface comes into contact with air during the process of sending the substrate from the glue tank to the dryer, which can easily attract dust and impurities, severely reducing the quality of the finished product.
[0004] Therefore, it is necessary to provide a coating equipment for copper-clad laminates to solve the above-mentioned technical problems. Utility Model Content
[0005] The purpose of this invention is to provide a coating equipment suitable for copper clad laminate production, which can clean the substrate before dipping and prevent the substrate from being contaminated with dust and impurities before drying, thus effectively improving production quality.
[0006] The objective of this utility model is achieved through the following technical solution.
[0007] A coating equipment suitable for copper clad laminate production includes: a cleaning component comprising a dust collection box having a first opening and a second opening, two dust collection rollers symmetrically arranged inside the dust collection box, the dust collection rollers being connected to a drive motor, and multiple brushes evenly distributed around the outer periphery of the dust collection rollers; and a coating impregnation tank for holding the coating solution, the tank having an inlet on one side and an outlet and a return outlet on the other side, the inlet communicating with the second opening, the return outlet being located below the outlet, and multiple guide rollers inside the coating impregnation tank. At least one of the guide rollers is immersed in the adhesive liquid; the scraping assembly includes a transfer box installed on the side of the impregnation tank, the transfer box encloses the discharge port and return port inside, and communicates with the interior of the impregnation tank through the discharge port and return port, the transfer box has a connection port on the side away from the impregnation tank, two scrapers are symmetrically arranged inside the transfer box, and an inclined guide plate is provided at the bottom of the transfer box; an oven is located on the side of the transfer box away from the impregnation tank, and the inlet of the oven is connected to the connection port.
[0008] In the above technical solution, during specific implementation, the copper-clad laminate substrate is fed by a material roller and enters the dust removal box through the first opening. Two dust removal rollers are symmetrically arranged vertically. The substrate passes between the two dust removal rollers. The dust removal rollers can rotate, allowing the brushes on their surfaces to scrub both sides of the substrate, removing dust and impurities adhering to the substrate surface. Subsequently, the substrate enters the impregnation box through the second opening and the feed port. Under the guidance of the guide rollers, it is immersed in the adhesive, allowing the adhesive to penetrate and adhere evenly to the substrate. After impregnation, the substrate enters the transfer box through the discharge port. The transfer box is equipped with two scrapers symmetrically arranged vertically. The substrate passes between the two scrapers, and the scrapers remove excess adhesive from the substrate and smooth the adhesive layer, ensuring a uniform adhesive layer thickness. The scraped adhesive falls onto the guide plate and, guided by the guide plate, returns to the impregnation box through the return port. After adhesive application, the substrate enters the drying oven through the connection port to dry the substrate and cure the adhesive, thus completing the adhesive application process. This application incorporates a cleaning component to clean the surface of the substrate before impregnation, preventing dust and impurities on the substrate from contaminating the adhesive and ensuring the quality of the impregnation. Furthermore, a transfer box is installed between the impregnation tank and the drying oven to prevent the substrate from directly contacting air during transport to the drying oven after impregnation, thus avoiding the re-absorption of dust and impurities and ensuring the quality of the finished product. Simultaneously, a guide plate is installed inside the transfer box, and through the guide plate and the return port on the impregnation tank, the adhesive scraped off by the scraper can be returned to the impregnation tank, reducing adhesive waste and saving costs.
[0009] In one example of this invention, the two dust removal rollers rotate in opposite directions.
[0010] In the above technical solution, when the two dust removal rollers rotate, the brushes on them can sweep the dust and impurities on both sides of the substrate to the side of the dust removal box away from the second opening, preventing the dust and impurities from falling into the impregnation box and contaminating the adhesive. At the same time, it also facilitates the unified collection of dust and impurities in the future.
[0011] In one example of this invention, the drive motor is mounted on the outside of the dust collection box.
[0012] In the above technical solution, the drive motor is installed outside the dust collection box, which facilitates the inspection and maintenance of the drive motor.
[0013] In one example of this utility model, the cleaning component further includes a vacuuming device, which is located on top of the dust collection box and has a suction nozzle located at the top of the dust collection box.
[0014] In the above technical solution, the dust collection device can use the dust collection nozzle to suck up the dust and impurities inside the dust collection box, and quickly suck away the dust and impurities brushed off by the dust collection roller to prevent them from remaining inside the dust collection box.
[0015] In one example of this utility model, the bottom of the dust collection box has a drain outlet.
[0016] In the above technical solution, the drain outlet is used to quickly discharge dust and impurities from the dust removal roller located on the lower side.
[0017] In one example of this invention, the end of the scraper is provided with an elastic adhesive layer.
[0018] In the above technical solution, the elastic adhesive layer is located at the end of the scraper close to the substrate. By setting the elastic adhesive layer, the scraping effect can be guaranteed while avoiding hard contact between the scraper and the substrate, so as to avoid damaging the substrate.
[0019] In one example of this utility model, the lower sidewall of the reflux port is an inclined wall.
[0020] In the above technical solution, by tilting the lower sidewall of the return port, it is beneficial for the adhesive to flow into the impregnation tank.
[0021] In one example of this utility model, the top of the impregnation tank is provided with an openable and closable cover.
[0022] In the above technical solution, the impregnation tank can be opened through the cover plate to replenish the adhesive inside the impregnation tank.
[0023] In one example of this utility model, the side of the impregnation tank is provided with an observation window.
[0024] In the above technical solution, the working status and remaining amount of adhesive inside the dipping tank can be observed through the observation window, which facilitates timely replenishment of adhesive.
[0025] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0026] This invention, by incorporating a cleaning component, can clean the surface of the substrate before impregnation with adhesive, preventing dust and impurities adhering to the substrate from contaminating the adhesive, ensuring the quality of the impregnation, extending the service life of the adhesive, and saving costs.
[0027] This invention provides a transfer box between the impregnation box and the drying oven, which can prevent the substrate from directly contacting the air during the process of sending it to the drying oven after impregnation, thereby avoiding the re-adsorption of dust and impurities and ensuring the quality of the finished product.
[0028] The transfer box of this utility model is equipped with a guide plate. Through the guide plate and the return port on the impregnation tank, the glue scraped off by the scraper can be sent back to the impregnation tank, reducing glue waste and saving costs. Attached Figure Description

Detailed Implementation
[0036] To facilitate understanding of this invention, a more comprehensive description will be provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of the invention. However, this invention can be implemented in many different forms and is not limited to the embodiments described herein.
[0037] Please refer to Figures 1 to 4A coating equipment suitable for copper clad laminate production includes a cleaning component 1, a coating tank 2, a coating scraping component 3, and an oven 4. The cleaning component 1 includes a dust collection box 11, which has a first opening 111 and a second opening 112. Two dust collection rollers 12 are symmetrically arranged inside the dust collection box 11, and each dust collection roller 12 is connected to a drive motor 13. Multiple brushes 121 are evenly distributed around the outer periphery of each dust collection roller 12. The coating tank 2 is used to hold the coating solution. One side of the coating tank 2 has an inlet 21, and the other side has an outlet 22 and a return outlet 23. The inlet 21 communicates with the second opening 112, and the return outlet 23 is located below the outlet 22. Multiple guide rollers 24 are arranged inside the coating tank 2, at least one of which... The guide roller 24 is immersed in the adhesive liquid; the scraping assembly 3 includes a transfer box 31 installed on the side of the impregnation tank 2. The transfer box 31 covers the discharge port 22 and the return port 23 inside, and communicates with the inside of the impregnation tank 2 through the discharge port 22 and the return port 23. The transfer box 31 has a connection port 311 on the side away from the impregnation tank 2. Two scrapers 32 are symmetrically arranged inside the transfer box 31. The bottom of the transfer box 31 has an inclined guide plate 33. The drying oven 4 is located on the side of the transfer box 31 away from the impregnation tank 2. The inlet of the drying oven 4 is connected to the connection port 311.
[0038] It is understandable that, such as Figure 1 and Figure 2 As shown, the left and right sides of this gluing equipment are equipped with rollers (not shown in the figure) for driving the copper-clad laminate substrate 5 to move. The first opening 111 is located on the left side of the dust collection box 11, the second opening 112 is located on the right side of the dust collection box 11, the inlet 21 is located on the left side of the impregnation box 2, and the outlet 22 is located on the right side of the impregnation box 2. The left and right sides of the drying oven 4 are respectively provided with an inlet and an outlet. When performing the gluing operation, the substrate 5 is driven from left to right by the rollers to pass through the dust collection box 11, the impregnation box 2, the transfer box 31 and the drying oven 4 to complete the gluing.
[0039] In practice, the substrate 5 is fed through the material rollers and enters the dust collection box 11 through the first opening 111. Two dust collection rollers 12 are symmetrically arranged vertically. The substrate 5 passes between the two dust collection rollers 12. The dust collection rollers 12 can rotate, causing the brushes 121 on their surfaces to brush the upper and lower surfaces of the substrate 5, removing dust and impurities adhering to the surface of the substrate 5. Subsequently, the substrate 5 enters the impregnation box 2 through the second opening 112 and the feed port 21. Under the guidance of the guide rollers 24, it is immersed in the adhesive, allowing the adhesive to penetrate evenly and adhere to the substrate 5. After impregnation... The substrate 5 enters the transfer box 31 through the discharge port 22. The transfer box 31 is equipped with two scrapers 32 arranged symmetrically at the top and bottom. The substrate 5 passes between the two scrapers 32. The scrapers 32 scrape off the excess adhesive on the substrate 5 and smooth the adhesive layer to ensure uniform adhesive layer thickness. The scraped adhesive falls onto the guide plate 33 and returns to the impregnation tank 2 through the return port 23 under the guidance of the guide plate 33. The substrate 5 after scraping enters the drying oven 4 through the connection port 311 to dry both sides of the substrate 5 and cure the adhesive. This completes the adhesive application process. This application, by setting up a cleaning component 1, can clean the surface of the substrate 5 before impregnation with adhesive, avoiding contamination of the adhesive by dust and impurities attached to the substrate 5, and ensuring the quality of impregnation. In addition, a transfer box 31 is set between the impregnation tank 2 and the drying oven 4 to prevent the substrate 5 from directly contacting the air during the process of being sent to the drying oven 4 after impregnation, thereby avoiding the re-adsorption of dust and impurities and ensuring the quality of the finished product. At the same time, a guide plate 33 is set inside the transfer box 31. Through the guide plate 33 and the return port 23 set on the impregnation tank 2, the adhesive scraped off by the scraper 32 can be sent back to the impregnation tank 2, reducing the waste of adhesive and saving costs.
[0040] Preferably, four guide rollers 24 are provided, two of which are located above the surface of the adhesive liquid and at the same height, and the other two guide rollers 24 are immersed in the adhesive liquid and at the same height. The guide rollers 24 guide the substrate 5 to be uniformly impregnated with adhesive.
[0041] Preferably, the first opening 111 and the second opening 112 are at the same height, which facilitates the substrate 5 to pass through the dust collection box 11 in a horizontal state, ensuring that the two dust collection rollers 12 are in full and uniform contact with both sides of the substrate 5, thus ensuring the cleaning effect.
[0042] It is understandable that, such as Figure 1 As shown, for ease of installation, the transfer box 31 in this embodiment has an opening on the left side, so that it can directly communicate with the interior of the impregnation tank 2 by covering the discharge port 22 and the return port 23. In other embodiments, a side wall can also be provided on the left side of the transfer box 31, and holes that cooperate with the discharge port 22 and the return port 23 can be opened on the side wall, which can also achieve the same technical effect.
[0043] Please refer to Figure 1 and Figure 3In this embodiment, the dust removal roller 12 located on the upper side rotates clockwise, and the dust removal roller 12 located on the lower side rotates counterclockwise. This allows the dust and impurities on both sides of the substrate 5 to be swept to the side of the dust removal box 11 away from the second opening 112, preventing dust and impurities from falling into the impregnation box 2 and contaminating the adhesive. At the same time, it also facilitates the unified collection of dust and impurities in the future.
[0044] Please refer to Figure 1 and Figure 3 In this embodiment, the cleaning component 1 also includes a dust collection device 14, which is located on the top of the dust collection box 11. The dust collection device 14 is provided with a dust collection nozzle 141 connected by a pipe. The dust collection nozzle 141 is located on the top of the inner side of the dust collection box 11. The dust collection device 14 can use the dust collection nozzle 141 to suck up the dust and impurities inside the dust collection box 11 and quickly suck away the dust and impurities brushed off by the dust collection roller 12 to prevent them from remaining inside the dust collection box 11.
[0045] Furthermore, due to the obstruction of the substrate 5, the dust and impurities brushed off the lower side of the substrate 5 are not easily sucked up by the dust suction nozzle 141. Therefore, a drain port 113 is opened at the bottom of the dust collection box 11 on the left side of the dust collection roller 12 to quickly discharge the dust and impurities brushed off by the dust collection roller 12 on the lower side to the outside of the dust collection box 11, so as to avoid the accumulation of dust and impurities inside the dust collection box 11.
[0046] It should be noted that the vacuuming device 14 is a common industrial vacuum cleaner in the prior art, and its specific structure will not be described in detail here.
[0047] Please refer to Figure 4 In this embodiment, the drive motor 13 is installed outside the dust collection box 11. Installing the drive motor 13 outside the dust collection box 11 facilitates the inspection and maintenance of the drive motor 13.
[0048] Please refer to Figure 2 In this embodiment, an elastic adhesive layer 321 is provided at the end of the scraper 32. The elastic adhesive layer 321 is located at the end of the scraper 32 near the substrate 5 and is made of rubber, thus having a certain degree of elasticity. By providing the elastic adhesive layer 321, the scraping effect is ensured while avoiding hard contact between the scraper 32 and the substrate 5, so as to avoid damaging the substrate 5.
[0049] Preferably, in order to ensure that all the adhesive scraped by the scraper 32 falls onto the guide plate 33, the scraper 32 is installed on the right side inside the transfer box 31, and the guide plate 33 is located on the left side of the scraper 32, which is conducive to fully recovering the adhesive scraped by the scraper 32.
[0050] Please refer to Figure 2 In this embodiment, the lower sidewall of the return port 23 is an inclined wall. By setting the lower sidewall of the return port 23 at an inclination, it is convenient for the adhesive to flow into the impregnation tank 2.
[0051] Please refer to Figure 1 and Figure 4 In this embodiment, the top of the impregnation tank 2 is provided with an openable cover plate 25, which can be used to open the impregnation tank 2 to replenish the glue inside the impregnation tank 2.
[0052] Furthermore, the side of the impregnation tank 2 is provided with an observation window 26. Through the observation window 26, the working status and glue level inside the impregnation tank 2 can be observed, making it convenient to replenish the glue in a timely manner.
[0053] Preferably, the side of the impregnation tank 2 is also provided with an openable door (not shown in the figure) to facilitate cleaning and maintenance of the interior of the impregnation tank 2.
