Description

Technical Field

[0001] The invention relates to the technical field of composite material impregnation, in particular to a full-automatic impregnation machine. Background Art

[0002] The impregnation system is widely used in the PCB industry. For example, the PP (prepreg) used in the copper clad laminate field is made by impregnating sheet materials such as paper or fiber fabrics and glass fibers with liquid resin. The resin-impregnated reinforcement material is heated and dried to make PP. It has the characteristics of strong design, light weight, high degree of automation, and high production efficiency. It is widely used in aerospace, civil engineering, sports and leisure, rail transportation, energy and power, etc. The impregnation of glass fiber cloth with resin determines the glue content of the fiber cloth and the mechanical strength after impregnation. The glue content and strength of the fiber cloth affect the comprehensive mechanical properties of the final product. Therefore, the impregnation process and equipment have an important influence on the performance of PP.

[0003] For example, the patent with publication number CN206873099U and name "A carbon fiber impregnation mechanism" includes a wire feeding frame, a wire feeding shaft, a dipping tank, guide rollers, a winding frame, a winding frame and a motor. The wire feeding frame is symmetrically arranged with several wire feeding shafts, the wire feeding shaft is wound with carbon fiber, a winding frame is arranged on the upper end of the winding frame, one side of the winding frame is connected to the motor output shaft, the carbon fiber passes through the dipping tank and is connected to the winding frame, and several guide rollers are arranged inside the dipping tank. The guide rollers are used to ensure that all the carbon fiber raw materials pass through the glue, so that the fiber cloth can be quickly impregnated with glue.

[0004] The glass fiber dipping effect has an important influence on the performance of PP and is a key step in the molding process. For example, in the above-mentioned patent, most of the prior art adopts open dipping when dipping the fiber cloth, that is, the resin is poured into the dipping tank, and the fiber cloth passes through the dipping tank. During the dipping, the glue liquid basically remains static, and the reinforcing material has a porous structure with a large number of tiny air masses inside its pores. When the glass fiber cloth is immersed in the resin glue, these small air masses cannot be discharged, so that a large number of tiny gases will remain inside the liquid resin attached to the surface of the reinforcing material to form small bubbles, so that the manufactured PP has quality defects such as microbubbles, weaving, and pinholes.

DETAILED DESCRIPTION

[0028] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0029] See also Figure 1-8The fully automatic glue dipping machine comprises a shell 1, a stirring mechanism is rotatably arranged at the bottom of the shell 1, a support plate 25 is fixedly arranged in the shell 1, a push plate 24 for pushing the glue liquid through the glass fiber cloth 3 is slidably arranged on the support plate 25, a feeding mechanism is arranged on the outer wall of the shell 1, a second lower pressing plate 35 is slidably arranged in the shell 1, and a driving mechanism is arranged in the shell 1. The driving mechanism drives the push plate 24 to move and drives the second lower pressing plate 35 to move downward at the same time, and squeezes out the bubbles in the glass fiber cloth 3 and the glue liquid by increasing the pressure. During the movement of the second lower pressing plate 35 and the push plate 24, the feeding mechanism is driven to quantitatively add glue liquid into the shell 1; the shell 1 is set to a "concave" shape, the second lower pressing plate 35 is above the push plate 24, the liquid level of the glue liquid is lower than the height of the push plate 24 in the initial state, and the support plate 25 is lower than the height of the liquid level, and the feeding mechanism is arranged. The mechanism is used to add glue into the shell 1. Two guide rollers 8 for changing the traveling direction of the glass fiber cloth 3 are rotatably arranged in the shell 1. A recovery device capable of driving the glass fiber cloth 3 forward and making the glass fiber cloth 3 tight is arranged above the shell 1 (this is the prior art, not shown in the figure, and will not be described in detail here). When in use, the glass fiber cloth 3 is inserted from the end of the shell 1 away from the push plate 24 and passes under the two guide rollers 8, and then passes through the second lower pressing plate 35, so that the glass fiber cloth 3 is in the shape of a "J". The glass fiber cloth 3 is unwound in a taut state by the recovery device, and appropriate resin glue is poured into the shell 1 so that the liquid level of the glue is at one-half of the push plate 24. The glass fiber cloth 3 is pulled to move by the recovery device. During the movement, the glass fiber cloth 3 drives the push plate 24 to reciprocate on the support plate 25 through the driving mechanism, such as Figure 2 As shown, when the push plate 24 moves toward the direction close to the glass fiber cloth 3, the glue between the glass fiber cloth 3 and the push plate 24 will be pushed to the side of the glass fiber cloth 3 away from the push plate 24, so that the glue passes through the hole in the middle of the glass fiber cloth 3, thereby squeezing out the gas in the hole of the glass fiber mesh, and at the same time making the glue fully adhere to the mesh of the glass fiber cloth 3, part of the gas discharged from the hole of the glass fiber cloth 3 will float to the surface of the glue, and another part will adhere to the surface of the glass fiber cloth 3, preventing the glue from adhering to the glass fiber cloth 3, or forming micro bubbles in the glue adhering to the glass fiber cloth 3, affecting the product quality. While the driving mechanism drives the push plate 24 to move back and forth, the driving mechanism drives the second The lower pressure plate 35 moves back and forth up and down, and the second lower pressure plate 35 fits tightly against the inner wall of the shell 1. When the second lower pressure plate 35 moves downward, the air on the upper part of the glue liquid is squeezed to increase the air pressure between the second lower pressure plate 35 and the glue liquid. At this time, the pressure in the glue liquid increases, and the gas attached to the surface of the glass fiber cloth 3 and part of the gas in the holes of the glass fiber cloth 3 move toward the upper surface of the glue liquid, which greatly reduces the generation of microbubbles. At the same time, by increasing the pressure of the glue liquid, the bubbles originally in the glue liquid and the bubbles squeezed out from the holes of the glass fiber cloth 3 can rise quickly. The push plate 24 cooperates with the second lower pressure plate 35 to enable the feeding mechanism to continuously replenish the glue liquid into the shell 1, without the need for manual addition of glue liquid.

[0030] In another embodiment of the present invention: the first lower pressing plate 34 is fixedly arranged on the second lower pressing plate 35, a fixing plate 7 is arranged between the first lower pressing plate 34 and the second lower pressing plate 35, the fixing plate 7 is fixedly connected to the inner wall of the shell 1, and the fixing plate 7, the first lower pressing plate 34 and the second lower pressing plate 35 are all provided with through grooves 9 for the glass fiber cloth 3 to pass through; the first lower pressing plate 34 is slidably connected to the inner wall of the shell 1, the first lower pressing plate 34 is tightly abutted against the inner wall of the shell 1, and the glass fiber cloth 3 is exactly in the middle position of the through groove 9 when in a taut state, and there is a very small gap between the edge of each through groove 9 and the glass fiber cloth 3, and the glass fiber cloth 3 After the cloth 3 is immersed in the glue and then comes out of the glue, there will be excess glue attached to the surface of the glass fiber cloth 3 to form liquid beads that move with the glass fiber cloth 3. If the liquid beads are not cleaned, bulges will be formed on the surface of the glass fiber cloth 3 after drying and fixing, causing the resin on the surface of the glass fiber cloth 3 to be uneven. A plurality of one-way valves 6 are fixedly arranged on the shell 1, and each one-way valve 6 is located between the second lower pressure plate 35 and the fixed plate 7. The gas in the shell 1 can go out from the one-way valve 6, but the gas cannot enter the shell 1 through the one-way valve 6. When the second lower pressure plate 35 moves downward to increase the pressure in the shell 1, the first lower pressure plate 34 also moves downward accordingly. At this time, the first The air between the lower pressing plate 34 and the fixed plate 7 is squeezed, and a negative pressure is generated between the second lower pressing plate 35 and the fixed plate 7, so that the air between the first lower pressing plate 34 and the fixed plate 7 quickly flows to the space between the second lower pressing plate 35 and the fixed plate 7 through the through groove 9 on the fixed plate 7. When the air flows downward from the through groove 9 on the fixed plate 7, the liquid droplets on the glass fiber cloth 3 passing through the fixed plate 7 can be blown off, and the glue on the glass fiber cloth 3 can be leveled. During the downward movement of the second lower pressing plate 35, part of the air between the second lower pressing plate 35 and the glue overflows from the through groove 9 on the second lower pressing plate 35 to Part of the gas between the fixed plate 7 and the second lower pressing plate 35, and between the first lower pressing plate 34 and the fixed plate 7 flows out through the through grooves 9 on the first lower pressing plate 34. It should be noted that the speed at which the second lower pressing plate 35 and the first lower pressing plate 34 move downward to increase the pressure is much faster than the speed at which the through grooves 9 release the gas to reduce the pressure. When the second lower pressing plate 35 moves upward, negative pressure is generated between the second lower pressing plate 35 and the glue, and between the first lower pressing plate 34 and the fixed plate 7. At this time, the gas flows downward rapidly through the through grooves 9 on the first lower pressing plate 34 and the second lower pressing plate 35, thereby blowing off the liquid droplets on the glass fiber cloth 3.

[0031] Specifically, the driving mechanism includes driven gears 16 rotatably arranged on both sides of the shell 1, and a driving rod 17 is rotatably arranged on each driven gear 16, and a connecting frame 23 is fixedly arranged on the push plate 24, and a movable plate 21 is slidably arranged on both sides of the shell 1, and each movable plate 21 is fixedly connected to the connecting frame 23, and each movable plate 21 is provided with an arc groove 22 that cooperates with the driving rod 17; each driving rod 17 is located in each arc groove 22 in a one-to-one correspondence. When in use, the two driven gears 16 are rotated at the same time. When the two driven gears 16 rotate, the movable plate 21 is driven to reciprocate through the corresponding arc groove 22, thereby driving the push plate 24 to reciprocate through the connecting frame 23.

[0032] Furthermore, lifting frames 33 are fixedly provided on both sides of the first lower pressure plate 34, and a slider 32 is fixedly provided on one end of each lifting frame 33 close to the driven gear 16, and each slider 32 is slidably connected to the housing 1, and a connecting plate 31 is rotatably provided on each slider 32, and one end of each connecting plate 31 away from the slider 32 is rotatably connected to each driving rod 17 in a one-to-one correspondence; when the driven gear 16 rotates, the corresponding end of the connecting plate 31 is driven up and down by the driving rod 17, and then the corresponding slider 32 is driven up and down, thereby driving the first lower pressure plate 34 and the second lower pressure plate 35 to reciprocate up and down. In the initial state, each driving rod 17 is at the top end of the corresponding arc groove 22, and the curvature of the arc groove 22 is less than 180 degrees. Figure 3 As shown, when in use, the two driven gears 16 are driven to rotate clockwise, and each driving rod 17 first moves downward along the corresponding arc groove 22. At this time, the moving plate 21 will not move. When the driving rod 17 moves to the lower end of the arc groove 22, the driven gear 16 continues to rotate clockwise. During the process of the driving rod 17 rotating upward from the bottom of the arc groove 22 to the middle of the arc groove 22, the driving rod 17 drives the moving plate 21 to move left. At this time, the push plate 24 moves in the direction close to the glass fiber cloth 3. During the process of the driving rod 17 rotating upward from the middle position of the arc groove 22 to the top of the arc groove 22, the moving plate 21 moves left to the initial position. Since the holes of the glass fiber cloth 3 are small, the reflux speed of the glue pushed to the left side of the glass fiber cloth 3 by the push plate 24 is limited without applying external force. The second lower pressing plate 35 moves downward and squeezes the glue by air pressure to accelerate the reflux of the glue, which is convenient for the push plate 24 to push the glue next time.

[0033] In another embodiment of the present invention, a screw rod 11 is rotatably provided on the bottom wall of the housing 1, a first bevel gear 12 is fixedly provided on the top of the screw rod 11, a synchronization rod 14 is rotatably provided in the housing 1, a second bevel gear 13 meshing with the first bevel gear 12 is fixedly provided on the synchronization rod 14, and driving gears 15 are fixedly provided at both ends of the synchronization rod 14; each driving gear 15 meshes with each driven gear 16 in a one-to-one correspondence, a servo motor 2 is fixedly provided at the bottom of the housing 1, and the output end of the servo motor 2 is fixedly connected to the screw rod 11, and the servo motor 2 drives the screw rod 11 to rotate. When the screw rod 11 rotates, the glue at the bottom of the housing 1 can be flipped upward, so that the glue at the bottom of the housing 1 can be fully utilized, and the ingredients in the glue can be prevented from flocculating, and the various ingredients in the glue can be fully mixed. When the screw rod 11 rotates, the second bevel gear 13 is driven to rotate through the first bevel gear 12, and the second bevel gear 13 drives the synchronization rod 14 to rotate. When the synchronization rod 14 rotates, it can drive the two driving gears 15 to rotate synchronously, and then the two driven gears 16 rotate synchronously.

[0034] In another embodiment of the present invention: the feeding mechanism includes a feeding box 4 fixedly arranged on the shell body 1, a feeding pipe 43 is fixedly arranged on the side of the shell body 1 close to the feeding box 4, a connecting pipe 49 is fixedly connected between the feeding pipe 43 and the feeding box 4, and a pushing column 44 is slidably arranged in the feeding pipe 43; the feeding pipe 43 passes through the shell body 1 and is connected to the inside of the shell body 1, the pushing column 44 is slidably arranged at the end of the feeding pipe 43 away from the shell body 1, the feeding pipe 43 is connected to the feeding box 4 through the connecting pipe 49, and a one-way valve 6 is also fixedly arranged in the connecting pipe 49 (not marked in the figure), through the one-way valve 6 in the connecting pipe 49, the glue can only flow from the feeding box 4 to the feeding pipe 43, and a semipermeable membrane that only allows air to pass through is fixedly arranged on the upper surface of the feeding pipe 43, and the pressure in the feeding pipe 43 is balanced by the semipermeable membrane.

[0035] Furthermore, a fixed frame 42 is fixedly provided on one side of the shell 1 close to the feeding pipe 43, a first rotating frame 41 is fixedly provided on the side of the connecting frame 23 away from the driven gear 16, a second rotating frame 45 is fixedly provided on the end of the feeding pipe 43 away from the shell 1, a moving block 46 is slidably provided in the second rotating frame 45, and a rotating frame 48 is rotatably provided on the fixed frame 42; the middle part of the rotating frame 48 is rotatably connected to the fixed frame 42, and the bottom end of the rotating frame 48 is movably connected to the first rotating frame 41, that is, the rotating frame 48 can be moved in the first rotating frame 41. The rotating frame 48 can slide on the first rotating frame 48 and rotate on the first rotating frame 48. The top of the rotating frame 48 is movably connected with the moving block 46. When the driven gear 16 drives the moving plate 21 and the connecting frame 23 to move away from the glass fiber cloth 3 through the arc groove 22, the bottom of the rotating frame 48 is moved away from the feeding pipe 43 through the first rotating frame 41, so that the moving block 46 pushes the pushing column 44 to move toward the shell 1 through the rotating frame 48, so that the glue in the feeding pipe 43 is pushed into the shell 1.

[0036] Furthermore, a blocking plate 39 is rotatably arranged inside the shell 1, an abutment rod 36 is fixedly arranged at the bottom of the second lower pressure plate 35, and a spring 47 is fixedly arranged between the moving block 46 and the pushing column 44; the feeding pipe 43 passes through the shell 1, and the blocking plate 39 is used to block the feeding pipe 43. In the initial state, the feeding pipe 43 is blocked by the blocking plate 39. When the push plate 24 moves in the direction close to the glass fiber cloth 3, the moving block 46 is driven to move in the direction away from the shell 1 through the rotating frame 48, and the feeding pipe 43 is blocked by the blocking plate 39. Figure 3 and Figure 6 At this time, the spring 47 makes the push column 44 on the right side of the connecting pipe 49. At this time, the glue in the feeding box 4 can enter the feeding pipe 43 through the connecting pipe 49. When the push plate 24 moves away from the glass fiber cloth 3, the moving block 46 moves toward the shell 1. Since the feeding pipe 43 is full of glue at this time, the push column 44 will not move when the moving block 46 moves toward the shell 1, and the spring 47 will be compressed. With the rotation of the driven gear 16, when the driving rod 17 moves upward from the middle of the arc groove 22 to the top of the arc groove 22, the moving plate 21 moves to the right. When the driven gear 16 continues to rotate to the limit, the driving rod 17 drives the second lower pressure plate 35 to move downward through the connecting plate 31. During the downward movement of the second lower pressure plate 35, the abutment rod 36 presses the sealing plate 39 away from one end of the feeding pipe 43, so that the sealing plate 39 that blocks the end of the feeding pipe 43 is lifted upward, thereby releasing the feeding pipe 43. At this time, the spring 47 extends, and the glue in the feeding pipe 43 is pushed into the shell 1 through the pushing column 44. The connecting pipe 49 is blocked while the pushing column 44 moves, thereby ensuring that the glue injected into the shell 1 each time remains within a certain range.

[0037] Specifically, a fixing rod 37 is fixedly arranged in the shell 1, a torsion spring 38 is fixedly arranged between the fixing rod 37 and the blocking plate 39, and an arc plate 391 is fixedly arranged on the blocking plate 39; the torsion spring 38 enables the blocking plate 39 to block the port of the feeding pipe 43 in a natural state, and during the downward movement of the second lower pressure plate 35, the abutment rod 36 first abuts against the end of the blocking plate 39 away from the feeding pipe 43, so that the blocking plate 39 rotates, and then the port of the feeding pipe 43 is released, and as the blocking plate 39 rotates, the abutment rod 36 gradually separates from the blocking plate 39, and at this time, the torsion spring 38 is used to block the port of the feeding pipe 43. 8 makes the blocking plate 39 block the port of the feeding pipe 43 again. When the driving rod 17 moves upward from the bottom end of the arc groove 22, the abutting rod 36 also moves upward. When the abutting rod 36 moves upward and abuts against the blocking plate 39 again, it will drive the blocking plate 39 to rotate downward at the end close to the feeding pipe 43. At this time, the arc plate 391 can make the blocking plate 39 always block the feeding pipe 43 when the second lower pressure plate 35 moves upward. When the driving rod 17 moves from top to bottom from the top of the arc groove 22, the spring 47 is in a compressed state. There is glue in the feeding pipe 43. As the driving rod 17 moves downward, The second lower pressing plate 35 moves downward, thereby driving the blocking plate 39 to rotate through the abutment rod 36, thereby releasing the port of the feeding tube 43. At this time, the spring 47 is extended, and the glue in the feeding tube 43 is pushed into the shell 1 through the pushing column 44. As the second lower pressing plate 35 moves downward, the abutment rod 36 is separated from the blocking plate 39. At this time, the blocking plate 39 blocks the feeding tube 43 again through the torsion spring 38. When the driving rod 17 moves upward from the bottom end of the arc groove 22 to the middle of the arc, the moving plate 21 drives the moving block 46 to move away from the shell 1. At this time, the pushing column 44 moves away from the shell 1. When the driving rod 17 moves upward from the middle of the arc groove 22 to the top of the arc groove 22, the moving plate 21 moves toward the moving block 46. At this time, the moving block 46 is moved toward the shell 1 by the rotating frame 48, so that the spring 47 is compressed. As the driven gear 16 continues to rotate, the second lower pressing plate 35 moves downward again, and then the glue in the feeding tube 43 is pushed into the shell 1 again. Through the cooperation of the blocking plate 39 and the pushing column 44, the glue can be quantitatively supplemented into the shell 1 intermittently.

[0038] Vertical plates 26 are fixedly provided on both sides of the support plate 25, and a plurality of rotating rods 27 are rotatably provided between the two vertical plates 26. A rubber ring 5 is fixedly provided on one end of the shell 1 away from the vertical plates 26; the distance between the glass fiber cloth 3 and the inner wall of the shell 1 is reduced by the two vertical plates 26, so that more glue can pass through the glass fiber cloth 3 when the push plate 24 moves. When the push plate 24 pushes the glue to pass through the glass fiber cloth 3, the glass fiber cloth 3 is supported by the rotating rod 27 to prevent the glass fiber cloth 3 from bending and increasing the gap between the glass fiber cloth 3 and the inner wall of the shell 1, so as to ensure that more glue passes through the glass fiber cloth 3. The rubber ring 5 is provided at one end of the shell 1 away from the rotating rod 27, that is, the cloth inlet of the glass fiber cloth 3. The rubber ring 5 is in contact with the surface of the glass fiber cloth 3. The rubber ring 5 increases the sealing performance of the end of the shell 1 away from the rotating rod 27 by the rubber ring 5, so as to prevent the glue liquid level away from the end of the rotating rod 27 from rising rapidly when the second lower pressing plate 35 moves downward, so as to reduce the pressure between the second lower pressing plate 35 and the liquid level.

[0039] Working principle: The servo motor 2 drives the screw rod 11 to rotate, and when the screw rod 11 rotates, it drives the first bevel gear 12 and the second bevel gear 13 to rotate, and then drives the two driven gears 16 to rotate synchronously through the synchronization rod 14 and the driving gear 15. When the two driven gears 16 rotate, the driving rod 17 and the arc groove 22 cooperate to make the moving plate 21 reciprocate, and at the same time, the second lower pressing plate 35 is driven to move up and down through the connecting plate 31. In the process of the reciprocating movement of the moving plate 21, the glue in the feeding box 4 can be released into the feeding pipe 43 through the rotating frame 48, and it The glue is pushed into the shell 1 to replenish the glue, and the push plate 24 can be used to make the glue pass through the glass fiber cloth 3, squeeze out the bubbles in the glass fiber cloth 3, and make the glue fully infiltrate the glass fiber cloth 3. In the process of the second lower pressure plate 35 moving up and down, the pressure between the second lower pressure plate 35 and the glue can be increased, so that the bubbles attached to the surface of the glass fiber cloth 3 and the holes are pressed out, and the microbubbles on the surface of the glass fiber cloth 3 are reduced. At the same time, the glue droplets on the surface of the glass fiber cloth 3 can be blown off by the rapid flow of gas, and the rotation of the sealing plate 39 can be controlled to quantitatively replenish the glue into the shell 1.
