Under the combined action of the first and second impregnation rollers, simultaneous impregnation of both sides of the prepreg can be achieved. This integrated operation improves the continuity, automation level, and overall processing efficiency of the impregnation process.

Description

Technical Field

[0001] This utility model relates to the technical field of copper clad laminate processing equipment, and more specifically, to an impregnation device for prepreg for copper clad laminates. Background Technology

[0002] Prepreg, also known as "PP sheet", is one of the main materials in the production of multilayer boards. It is mainly composed of resin and reinforcing materials. The reinforcing materials are divided into several types such as fiberglass cloth, paper base, and composite materials. Most of the prepregs (bonding sheets) used to make multilayer printed circuit boards use fiberglass cloth as the reinforcing material.

[0003] The currently used prepreg dipping equipment can only perform dipping on one side of the material and cannot perform double-sided dipping simultaneously. This operation mode has limited efficiency, resulting in longer production cycles and reduced resource utilization, making it difficult to meet the needs of high-efficiency and large-scale production. This technical limitation not only affects the continuity of the overall process flow, but may also cause potential problems in terms of dipping uniformity and quality consistency, highlighting the inadequacy of the existing equipment's automation level and easily reducing its working efficiency. Utility Model Content

[0005] (II) Technical Solution To achieve the advantages of simultaneously impregnating both sides of the prepreg with adhesive, resulting in high work efficiency and automation, the specific technical solution adopted by this utility model is as follows: An impregnation device for prepreg in copper-clad laminates includes a tank. A second motor is fixedly mounted on the front surface of the tank, and a second impregnation roller is fixedly connected to the output end of the second motor. Connecting frames are fixedly connected to both sides of the tank, and electric push rods are fixedly mounted on both sides of the lower top surface of the connecting frames. A push plate is fixedly connected to the output end of the electric push rod, and a first impregnation roller is fixedly mounted at the middle position of the bottom surface of the push plate. A spray pipe is fixedly connected to the bottom surface of the push plate on one side of the first impregnation roller, and a spray nozzle is fixedly mounted on the spray pipe. A pump body is fixedly mounted on one side of the top surface of the connecting frame, and the pump body is connected to the tank through a suction pipe and to the spray pipe through a delivery pipe.

[0006] Furthermore, the bottom surface of the tank is provided with legs on both sides, and a horizontal plate is fixedly connected between the legs. A shaft seat is fixedly installed at the middle position of the top surface of the horizontal plate, and a rotating rod is installed in the shaft seat. The top end of the rotating rod passes through the bottom surface of the tank and is fixedly connected with an agitator. A first motor is fixedly installed on one side of the bottom surface of the tank, and a synchronous pulley is fixedly installed on the output end of the first motor and the rotating rod. A synchronous belt is installed between the synchronous pulleys.

[0007] Furthermore, through openings are provided on both sides of the connecting frame.

[0008] Furthermore, there are multiple nozzles, which are evenly distributed on the spray pipe, and the spray pipe and nozzles are matched with the first dip roller.

[0012] (III) Beneficial Effects Compared with the prior art, the present invention provides an impregnation device for prepreg in copper clad laminates, which has the following advantages: (1) In this utility model, starting the second motor located on the front surface of the tank body can drive the second dip roller to rotate to participate in the dip operation. At the same time, the pump body at the top of the connecting frame is turned on, and the adhesive liquid is drawn from the tank body through the extraction pipe and transported to the spray pipe at the bottom of the push plate through the conveying pipe. The adhesive liquid is evenly sprayed onto the surface of the first dip roller by the nozzle on the spray pipe. The position of the push plate is adjusted by the electric push rod so that the first dip roller contacts the prepreg. Under the combined action of the first dip roller and the second dip roller, the simultaneous dip of the prepreg on both sides can be achieved. This integrated operation improves the continuity, automation level and overall processing efficiency of the dip process.

[0013] (2) In this utility model, starting the first motor located on one side of the bottom of the tank can drive the synchronous wheel to rotate, and then drive the rotating rod to rotate through the synchronous belt. The stirring blade at the top of the rotating rod will continuously stir the adhesive in the tank. This stirring process enhances the fluidity of the adhesive in the tank, effectively prevents the adhesive from coagulating or settling, and ensures the stability of the adhesive properties and the normal progress of the impregnation process.

[0018] According to an embodiment of the present invention, an apparatus for impregnating a prepreg for copper-clad laminates is provided.

[0019] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figures 1-4As shown, an impregnation device for a prepreg for copper-clad laminates according to an embodiment of the present invention includes a tank 1. A second motor 20 is fixedly installed on the front surface of the tank 1, and a second impregnation roller 11 is fixedly connected to the output end of the second motor 20. Connecting frames 2 are fixedly connected to both sides of the tank 1, and electric push rods 7 are fixedly installed on both sides of the lower top surface of the connecting frames 2. A push plate 8 is fixedly connected to the output end of the electric push rod 7, and a first impregnation roller 10 is fixedly installed at the middle position of the bottom surface of the push plate 8. A spray pipe 18 is fixedly connected to the bottom surface of the push plate 8 on one side of the first impregnation roller 10, and a nozzle 19 is fixedly installed on the spray pipe 18. A pump body 9 is fixedly installed on one side of the top surface of the connecting frames 2, and the pump body 9 is connected to the tank 1 through a suction pipe and to the spray pipe through a delivery pipe. The system is connected in section 18. A second motor 20 on the front surface of the start-up tank 1 drives the second dip roller 11 to rotate, thus performing dip coating on the prepreg. A pump 9 on the top surface of the connecting frame 2 is activated, and the pump 9 transports the adhesive from the tank 1 through a suction pipe to a spray pipe 18 on the bottom surface of the push plate 8. The adhesive is then sprayed onto the first dip roller 10 through nozzles 19 on the spray pipe 18. An electric push rod 7 is activated, moving the push plate 8. When the first dip roller 10 contacts the prepreg, the combined use of the first and second dip rollers 10 and 11 allows for simultaneous dip coating on both sides of the prepreg, improving work continuity and automation, thereby increasing processing efficiency.

[0020] Please see Figure 1 The bottom surface of the tank 1 is provided with support legs 6 on both sides, and a horizontal plate 14 is fixedly connected between the support legs 6. A bearing seat is fixedly installed at the middle position of the top surface of the horizontal plate 14, and a rotating rod 4 is installed in the bearing seat. The top end of the rotating rod 4 passes through the bottom surface of the tank 1 and is fixedly connected to an agitator 5. A first motor 17 is fixedly installed on one side of the bottom surface of the tank 1, and a synchronous pulley 15 is fixedly installed on the output end of the first motor 17 and the rotating rod 4. A synchronous belt 16 is installed between the synchronous pulleys 15. When the first motor 17 on one side of the bottom surface of the tank 1 is started, the first motor 17 drives the synchronous pulley 15 to rotate. Through the use of the synchronous belt 16, the rotating rod 4 can be driven to rotate, so that the agitator 5 at the top end of the rotating rod 4 rotates in the tank 1. Through the use of the agitator 5, the adhesive in the tank 1 can be agitated, increasing the fluidity of the adhesive in the tank 1 and preventing the adhesive from solidifying in the tank 1, thereby maintaining its normal use.

[0021] Please see Figure 1 and Figure 4 The two sides of the connecting frame 2 are provided with through openings 3, which facilitates the conveying and impregnation of the prepreg.

[0022] Please see Figure 1 and Figure 2 There are multiple nozzles 19, and the multiple nozzles 19 are evenly distributed on the spray pipe 18. The spray pipe 18 and the nozzles 19 are matched with the first dip roller 10. By using the nozzles 19, the adhesive can be evenly sprayed onto the first dip roller 10. By using the first dip roller 10 and the second dip roller 11, both sides of the prepreg can be dipped in adhesive at the same time.

[0023] Please see Figure 1 and Figure 3 There are multiple support legs 6, and the multiple support legs 6 are evenly distributed in pairs on both sides of the bottom surface of the tank body 1. The support legs 6 are fixedly welded to the tank body 1. The support legs 6 support the tank body 1 and can maintain the stability of the tank body 1 during use.

[0024] Please see Figure 1 The first dip roller 10 is matched with the second dip roller 11. By using the first dip roller 10 and the second dip roller 11 together, both sides of the prepreg can be dipped simultaneously, which helps to improve its working efficiency.

[0025] Please see Figure 1 and Figure 3 A discharge pipe 13 is fixedly connected to one side surface of the tank 1, and a valve 12 is fixedly installed on the discharge pipe 13. By opening the valve 12 on the discharge pipe 13, the material in the tank 1 can be discharged.

[0026] The control switch control circuit can be implemented by simple programming by those skilled in the art. It is common knowledge in the field. Since it is only used and not modified, the control method and circuit connection will not be described in detail.

[0027] Working principle: The second motor 20 on the front surface of the tank 1 is activated, driving the second dip roller 11 to rotate, thus dipping the prepreg in adhesive. Simultaneously, the pump 9 on the top surface of the connecting frame 2 is activated, pumping the adhesive from the tank 1 through a suction pipe to a spray pipe 18 on the bottom surface of the push plate 8. The adhesive is then sprayed onto the first dip roller 10 through nozzles 19 on the spray pipe 18. The electric push rod 7 is activated, moving the push plate 8. When the first dip roller 10 comes into contact with the prepreg, the adhesive is applied through the first dip roller 10 and the second dip roller... The combined use of 11 allows for simultaneous impregnation of both sides of the prepreg, improving the continuity and automation of the work and thus increasing processing efficiency. Specifically, by activating the first motor 17 on one side of the bottom surface of the tank 1, the first motor 17 drives the synchronous pulley 15 to rotate. Through the use of the synchronous belt 16, the rotating rod 4 is driven to rotate, causing the agitator 5 at the top of the rotating rod 4 to rotate in the tank 1. The agitator 5 agitates the adhesive in the tank 1, increasing the fluidity of the adhesive in the tank 1 and preventing the adhesive from solidifying in the tank 1, thereby maintaining its normal use.
