Description

An adhesive coating device for copper clad laminates Technical Field

[0001] This utility model relates to the technical field of adhesive coating equipment, specifically an adhesive coating device for copper clad laminates. Background Technology

[0002] Copper clad laminates are generally divided into two main categories: rigid copper clad laminates and flexible copper clad laminates. Rigid copper clad laminates are usually composed of reinforcing materials and copper foil. During the processing of rigid copper clad laminates, the reinforcing materials are impregnated with resin and then dried in an oven to form a prepreg. Copper foil is coated with adhesive on one side and attached to the upper and lower surfaces of the prepreg. The laminates are then pressed together under high temperature and high pressure.

[0003] Currently, existing copper clad laminate coating equipment has some shortcomings in use. For example, the flow control of the adhesive liquid during the coating process is not precise enough, which can easily lead to uneven coating thickness and affect the quality of the copper clad laminate. At the same time, the structure of the equipment is not flexible enough and it is difficult to adapt to the coating requirements of copper clad laminates of different specifications and thicknesses. Therefore, we propose a copper clad laminate coating equipment to solve the above problems. Summary of the Invention

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] Please refer to Figures 1-4. A copper-clad laminate adhesive coating device includes a worktable 1 and a U-shaped frame 2 mounted on the upper surface of the worktable 1.

The output ends of the two hydraulic cylinders 31 pass through the interior of the U-shaped frame 2. A U-shaped plate 32 is fixedly installed on the output end of the hydraulic cylinder 31. Limiting blocks 33 are fixedly installed on the outer walls of both ends of the U-shaped plate 32. A coating roller 34 is rotatably connected inside the U-shaped plate 32.

[0027] In this embodiment, the programmable controller 9 starts the drive motor 5, which drives the unwinding roller 6 to rotate, releasing the copper-clad laminate to be coated and conveying it to the area below the coating roller 34 via the guide mechanism; the drive motor 7 synchronously drives the winding roller 8 to keep the copper-clad laminate taut and complete the winding after coating.

[0028] Based on the thickness of the copper clad laminate, the programmable controller 9 controls the output end of the hydraulic cylinder 31 to extend and retract, driving the U-shaped plate 32 to slide up and down along the limiting groove 4, adjusting the gap between the coating roller 34 and the surface of the copper clad laminate, and determining the target coating thickness.

[0029] Referring to Figures 3 and 4, the control structure 35 includes an adhesive tank 351. The outer wall of the adhesive tank 351 is fixedly installed on the upper surface of the U-shaped plate 32. A liquid level sensor 352 is fixedly installed inside the adhesive tank 351. A metering pump 353 is fixedly connected to the bottom of the adhesive tank 351. The metering pump 353 is fixedly installed inside the U-shaped plate 32. A main pipe 354 is fixedly connected to the bottom end of the metering pump 353. A branch pipe 355 is fixedly connected to the bottom end of the main pipe 354.

[0030] In this embodiment, the adhesive in the adhesive tank 351 is quantitatively extracted by the metering pump 353, and then distributed to several adhesive distribution pipes 355 through the main pipe 354. The adhesive is evenly sprayed onto the surface of the coating roller 34, and then the coating roller 34 coats the copper-clad laminate area by rolling. The liquid level sensor 352 is used to monitor the liquid level in the adhesive tank 351 in real time. When the liquid level is lower than the set threshold, a signal is sent to the programmable controller 9.

[0031] Referring to Figures 1-3, symmetrical limit grooves 4 are provided inside the U-shaped frame 2, and limit blocks 33 are slidably connected inside the limit grooves 4.

[0036] In use, the programmable controller 9 starts drive motor 5, which drives the unwinding roller 6 to rotate, releasing the copper-clad laminate to be coated. The laminate is then conveyed to the coating roller 34 via the guide mechanism. Drive motor 7 synchronously drives the take-up roller 8 to keep the copper-clad laminate taut and complete the winding after coating. According to the thickness of the copper-clad laminate, the programmable controller 9 controls the output end of the hydraulic cylinder 31 to extend and retract, driving the U-shaped plate 32 to slide up and down along the limiting groove 4, adjusting the gap between the coating roller 34 and the surface of the copper-clad laminate, and determining the target coating thickness. The adhesive in the adhesive tank 351 is quantitatively extracted by the metering pump 353 and distributed to several adhesive branch pipes 355 through the main pipe 354, which are evenly sprayed onto the surface of the coating roller 34. Then, the coating roller 34 coats the area of ​​the copper-clad laminate to be coated by rolling.
