Description

Technical Field

[0001] This utility model relates to the field of aluminum-based copper clad laminate processing technology, and in particular to an adhesive coating device for aluminum-based copper clad laminate processing. Background Technology

[0002] Aluminum-based copper clad laminate, also known as aluminum substrate, is a composite material widely used in the electronics industry. It is mainly used as the substrate material for printed circuit boards (PCBs) in the electronics industry, and has a significant impact on the performance, quality, manufacturability, cost, and long-term reliability of the PCBs.

[0003] The adhesive coating process can protect aluminum-based copper-clad laminates from environmental factors such as moisture, dust, and corrosion. For example, Chinese Patent Publication No. CN215395785U discloses a wood board adhesive coating machine for uniform coating. It includes a base, with a transport platform fixedly mounted on the top. The transport platform consists of transport rollers, a conveyor belt, and a drive motor. Support plates are located on both sides of the transport platform. A movable groove is located on one side of the support plate, and a mounting plate is located on one side of the movable groove. Adhesive coating rollers are movably mounted on one side of the mounting plate, and feeding rollers are located on one side of the adhesive coating rollers. A cylinder is fixedly mounted on one side of the top of the mounting plate, and the mounting plate is fixedly connected to the telescopic head at the bottom of the cylinder. A storage box is fixedly mounted on the top of the mounting plate near the cylinder, with a top cover on one side of the top cover and a feeding port on one side of the top of the storage box. A stirring rod is located inside the storage box. This invention uses a glue-applying roller to apply glue to the wood board twice, achieving uniform glue application on the wood board surface through two applications. This invention provides the advantage of uniform glue application, solves the problems mentioned in the background art, and has high practical value.

[0004] In practice, the coating roller and the conveying roller work together to coat and convey aluminum-based copper-clad laminates. However, after use, the excess adhesive on the surfaces of the coating roller and the conveying roller cannot be cleaned. Over time, the adhesive tends to solidify and become difficult to clean, affecting the efficiency and quality of the next processing. Utility Model Content

[0008] The processing table is also equipped with a mounting frame on top. The mounting frame moves laterally by adjusting the components to clean the adhesive on the surface of the glue-spreading roller and the glue-coating roller using a scraper.

[0009] The mounting bracket is also equipped with a cleaning component via an elastic structure, which is used to clean the adhesive residue adhering to the scraper.

[0010] Furthermore, the adjustment component includes a connecting seat, the two ends of the mounting frame are bent toward the glue feeding mechanism to form a bent portion, and the connecting seat is fixedly connected to the side of the mounting frame away from the bent portion.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figure 1-6 A coating device for processing aluminum-based copper-clad laminates includes a processing table 1, a conveying device 2 and a coating device 3 on the top of the processing table 1, the coating device 3 includes a support frame 31, a glue feeding mechanism 32 is provided in the support frame 31, and a glue spreading roller 33 and a glue coating roller 34 are rotatably connected below the glue feeding mechanism 32.

[0026] The top of the processing table 1 is also provided with a mounting frame 4. The mounting frame 4 is moved laterally by the adjustment component 5 so as to use the scraper 6 to clean the adhesive on the surface of the glue-spreading roller 33 and the glue-coating roller 34.

[0027] The mounting bracket 4 is also provided with a cleaning component 8 via an elastic structure 7, which is used to clean the adhesive on the scraper 6.

[0028] Furthermore, the adjustment component 5 includes a connecting seat 51, the two ends of the mounting frame 4 are bent toward the glue feeding mechanism 32 to form a bent portion 41, and the mounting frame 4 is fixedly connected to the connecting seat 51 on the side away from the bent portion 41. The top of the processing table 1 is fixedly connected to the two sides of the bottom of the mounting frame 4 with slide rails 52, and the connecting seat 51 is slidably connected in the slide rails 52.

[0029] Furthermore, a positioning glass bead 53 is embedded on the side of the connecting seat 51, and a pair of through holes 521 are provided on the side of the slide rail 52 to match the telescopic column end of the positioning glass bead 53.

[0030] In this embodiment, when the telescopic column end of the positioning glass bead 53 engages with the through hole 521 near the support frame 31, a pair of scrapers 6, driven by the mounting frame 4, come into contact with the glue-spreading roller 33 and the glue-applying roller 34. Then, because the glue-spreading roller 33 and the glue-applying roller 34 are in contact and rotate in the same direction, the scraped glue is collected in the collection box 9 under the action of gravity.

[0031] Conversely, when the telescopic column end of the positioning glass bead 53 engages with the through hole 521 on one side of the principle support frame 31, a pair of scrapers 6 disengage from the glue-spreading roller 33 and the glue-applying roller 34.

[0032] Furthermore, the scraper blade 6 is made of plastic or rubber.

[0033] More specifically, the top of the bending portions 41 on both sides is fixedly connected to the scraper 6, wherein the glue-spreading roller 33 and the glue-applying roller 34 are attached to each other and rotate in the same direction, and a pair of scrapers 6 are attached to the glue-spreading roller 33 and the glue-applying roller 34 respectively. A collection box 9 for collecting glue is also placed on the top of the processing table 1.

[0034] In general, the two sides of the bending portion 41 are provided with guide grooves 411 that connect the sides, the cleaning component 8 is slidably connected to the guide grooves 411 and avoids the scraper 6 through the relief groove 81;

[0035] The cleaning component 8 has a collection chamber inside, and a scraping groove 82 adapted to the scraper 6 is located in the middle of the chamber.

[0036] Finally, the elastic structure 7 includes a deformation groove 71. A pair of deformation grooves 71 with connecting sides are provided on both sides of the guide groove 411. A limiting protrusion 72 is provided inside the deformation groove 71 on the movable side. The cleaning member 8 is located between the limiting protrusions 72 on both sides, and the cleaning member 8 abuts against and slides against the limiting protrusions 72.

[0037] In this embodiment, the mounting bracket 4 is preferably made of a deformable material such as rubber or plastic. The cleaning component 8 is positioned between the limiting protrusions 72 on both sides to prevent free sliding. When the cleaning component 8 slides, the adhesive on the side of the scraper 6 is pushed into the collection cavity by the scraper groove 82. The adhesive is cleaned by disassembling the cleaning component 8.

[0038] Furthermore, as the adhesive accumulates at the bottom of the scraper blade 6, to prevent the adhesive from shifting to the other side of the scraper blade 6 when pushed, one side of the bottom of the scraper groove 82 can extend towards one side of the scraper blade 6 and abut against the bending part 41, further increasing the contact area between the scraper groove 82 and the adhesive.

[0039] Working method: During operation, the aluminum-based copper-clad laminate is conveyed to the bottom of the glue coating device 3 by the conveying device 2. The glue feeding mechanism 32 feeds glue to the glue spreading roller 33 and the glue coating roller 34. The glue spreading roller 33 and the glue coating roller 34 are attached and rotate in the same direction to apply glue to the aluminum-based copper-clad laminate.

[0040] After the glue is applied, when the telescopic column end of the positioning glass bead 53 engages with the through hole 521 on the side near the support frame 31, a pair of scrapers 6, driven by the mounting frame 4, come into contact with the glue-spreading roller 33 and the glue-applying roller 34. Then, because the glue-spreading roller 33 and the glue-applying roller 34 are in contact and rotate in the same direction, the scraped glue is collected in the collection box 9 under the action of gravity.

[0041] Conversely, when the telescopic column end of the positioning glass bead 53 engages with the through hole 521 on one side of the principle support frame 31, a pair of scrapers 6 disengage from the glue-spreading roller 33 and the glue-applying roller 34.

[0042] Then, the cleaning component 8 contacts and slides against the limiting protrusion 72 through the deformation groove 71. While the cleaning component 8 is sliding, it scrapes the adhesive at the bottom of the scraper 6 into the collection cavity through the scraper groove 82.

[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
