Description

Technical Field

[0001] This utility model relates to the field of prepreg production technology, and in particular to a resin uniform coating device for a prepreg impregnation machine. Background Technology

[0002] Prepreg is a key material in the manufacture of multilayer printed circuit boards. It is made by pre-impregnation of resin (such as epoxy resin) and reinforcing materials (such as fiberglass cloth) and is in a partially cured state (stage B) to facilitate subsequent compression molding.

[0003] Patent CN215321283U discloses an impregnation device for producing copper-clad laminate prepreg, comprising an impregnation assembly, a vertical plate, a first roller assembly, and a second roller assembly. While this patent uses a limiting plate to position the glass cloth outside the roller body, preventing it from tilting during impregnation and ensuring normal operation of the device, uneven resin coating can occur due to surface wrinkles or unevenness. Furthermore, after resin coating, uneven resin distribution, even bubbles or uneven thickness, can arise from fluctuations during transport, thus affecting the quality of subsequent curing and lamination processes.

[0004] Therefore, a resin uniform coating device for a prepreg impregnation machine is needed. Utility Model Content

[0005] In order to overcome the shortcomings of existing patents, such as uneven resin coating caused by surface wrinkles or unevenness of glass cloth during impregnation, and uneven resin distribution, even bubbles or uneven thickness, due to the fluctuations during the transportation process after resin coating, which affects the quality of subsequent curing and lamination processes, this utility model provides a resin uniform coating device for a prepreg impregnation machine.

[0006] The technical solution of this utility model is: a resin uniform coating device for a semi-cured sheet impregnation machine, comprising a support frame, a motor, a conveyor, a support frame, a water pump, a high-pressure nozzle, a connecting pipe, and a drying component. A motor is installed on the front right side of the support frame, and a conveyor is installed inside the support frame. The output shaft of the motor is connected to the conveyor. Two support frames are fixedly connected to the left side of the support frame. A water pump is installed on the front side of the support frame, and a connecting pipe is connected to the top of the water pump. A high-pressure nozzle is installed at one end of the connecting pipe inside the support frame. A drying component is installed inside the support frame to dry the semi-cured sheet, keeping the resin coated on its surface in a semi-dry state. The device also includes a fixed rod, rollers, and a scraper. A fixed rod is slidably installed on the left side inside the support frame, and rollers are rotatably installed on the fixed rod. A scraper is slidably installed in the middle position inside the support frame.

[0007] In one embodiment, the drying assembly includes a fixing frame and an ultraviolet lamp, with the fixing frame installed inside the right side of the support frame and the ultraviolet lamp installed inside the fixing frame.

[0008] In one embodiment, the support frame is further provided with a hinge, a limiting plate, a rubber plate, and a locking plate. A hinge is installed on one side of the support frame, and a limiting plate is hinged to the hinge. The limiting plate can contact the support frame. A rubber plate is adhered to the inner wall of the limiting plate. Locking plates are fixedly connected to both sides of the limiting plate and are locked to the support frame.

[0009] In one embodiment, a handle is also included, with the handle fixedly connected to the side of the limiting plate away from the support frame.

[0010] In one embodiment, an isolation frame is also included, with the isolation frame provided at the front of the support frame, the isolation frame blocking the water pump.

[0011] In one embodiment, a bellows is also included, and the pump connector is connected to and communicates with the bellows.

[0012] Compared with the prior art, this utility model provides a resin uniform coating device for a prepreg impregnation machine, which has the following beneficial effects: 1. By contacting the material with the roller, the wrinkles on it are smoothed out, ensuring the stability of the coating process; the scraper adjusts the thickness of the sprayed resin to ensure that the resin is evenly distributed on the surface of the material, avoiding problems such as bubbles or uneven thickness caused by uneven coating, thereby improving the quality of resin coating.

[0013] 2. When the material is conveyed to the right side of the support frame, the ultraviolet lamp dries the material coated with resin, so that the resin can be cured quickly and kept in a semi-dry state for easy subsequent processing.

[0014] 3. By rotating the limiting plate upwards, the clamping plate engages with the support frame, thereby limiting and fixing the material roll to prevent it from shifting or detaching during transportation, which would affect the coating effect. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1: A resin uniform coating device for a prepreg impregnation machine, please refer to... Figures 1-6 The system includes a support frame 1, a motor 2, a conveyor 3, a support frame 4, a water pump 5, a high-pressure nozzle 6, a connecting pipe 7, and a drying assembly. The motor 2 is installed on the front right side of the support frame 1. The conveyor 3 is located inside the support frame 1, and the output shaft of the motor 2 is connected to the conveyor 3. Two support frames 4 are fixedly connected to the left side of the support frame 1. The water pump 5 is installed on the front side of the support frame 1, and the top of the water pump 5 is connected to and connected to the connecting pipe 7. A high-pressure nozzle 6 is installed at one end of the connecting pipe 7 inside the support frame 1. The drying assembly is located inside the support frame 1 and dries the semi-cured sheet to keep the resin coating on its surface semi-dry. The drying assembly includes a fixed frame 8 and an ultraviolet lamp 9. The drying assembly is located on the right side inside the support frame 1. A fixed frame 8 is installed, and an ultraviolet lamp 9 is installed inside the fixed frame 8. A fixed rod 14 is slidably installed on the left side inside the support frame 1, and a roller 15 is rotatably installed on the fixed rod 14. A scraper 16 is slidably installed in the middle of the support frame 1. Pulling the fixed rod 14 and the scraper 16 upward can adjust the distance between the roller 15, the scraper 16 and the conveyor 3, so as to adapt to materials of different thicknesses. An isolation frame 18 is set at the front of the support frame 1 to shield the water pump 5 and protect it from accidental contact with the water pump 5 during operation. The connector of the water pump 5 is connected to and connected to a corrugated pipe 19, which provides a certain degree of flexibility for easy connection with the resin container.

[0024] When this device is needed, first place the material roll on the support frame 4, then pull the material to flatten it and place it on the conveyor 3. Next, start the motor 2. The output shaft of the motor 2 rotates to drive the conveyor 3. During the conveying process, the roller 15 contacts the material, smoothing out the wrinkles and ensuring the stability of the coating process. The material continues to be conveyed to the area below the high-pressure nozzle 6. At this time, the water pump 5 runs and injects the resin into the high-pressure nozzle 6 through the connecting pipe 7. The resin is then evenly sprayed onto the surface of the material through the high-pressure nozzle 6. As the material is conveyed, the scraper 16 adjusts the thickness of the sprayed resin to ensure that the resin is evenly distributed on the surface of the material, avoiding problems such as bubbles or uneven thickness caused by uneven coating, thereby improving the quality of resin coating. Finally, when the material is conveyed to the right side of the support frame 1, the ultraviolet lamp 9 dries the material after coating with resin, allowing the resin to cure quickly and keeping it in a semi-dry state for easy subsequent processing.

[0025] Example 2: Based on Example 1, please refer to... Figure 1 , Figure 4 and Figure 5 A hinge 10 is installed on one side of the support frame 4. A limiting plate 11 is hinged to the hinge 10. The limiting plate 11 can contact the support frame 4. A rubber plate 12 is adhered to the inner wall of the limiting plate 11. A clamping plate 13 is fixedly connected to both sides of the limiting plate 11. The clamping plate 13 is engaged with the support frame 4. A handle 17 is fixedly connected to the side of the limiting plate 11 away from the support frame 4. The handle 17 is used to increase the force point and facilitate the adjustment of the position of the limiting plate 11, thereby realizing the limiting and fixing of the material roll.

[0026] After placing the material roll on the support frame 4, hold the handle 17 and rotate the limiting plate 11 upwards so that it contacts the support frame 4. At this time, the clamping plates 13 on both sides of the limiting plate 11 engage with the support frame 4, thereby limiting and fixing the material roll to prevent it from shifting or falling off during the conveying process and affecting the coating effect.

[0027] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. All equivalent substitutions made within the principles of this utility model should be included within the protection scope of this utility model. Contents not described in detail in this utility model are existing technologies known to those skilled in the art.
