[0002] Carbon fiber sheet is a sheet formed by impregnating carbon fiber with resin and then hardening it.

Carbon fiber sheet also has the advantages of light weight and high flexibility during use.

[0003] Chinese patent CN102173061B discloses a liquid resin degassing method and device for vacuum infusion molding of composite materials. The mixed resin enters a set degassing device, and the resin flows through the multi-layer spiral laminar flow plates inside the degassing device.

DETAILED DESCRIPTION

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] As introduced in the background technology, there are deficiencies in the prior art. In order to solve the above technical problems, the present application proposes a vacuum infusion device and a infusion method for the production of carbon fiber panels.

[0041] Example 1

[0042] See also Figure 1 - Fig. 9 A vacuum infusion device comprises a device body 1, a first vacuum chamber 2, a vacuum mechanism 4, a separation mechanism 5 and a feeding mechanism 6, wherein the first vacuum chamber 2 is provided inside the device body 1, the vacuum mechanism 4 is installed on one side of the device body 1, the separation mechanism 5 is installed inside the device body 1, the feeding mechanism 6 is installed outside the device body 1, the second vacuum chamber 3 is installed inside the first vacuum chamber 2, and the molding mechanism 7 is installed inside the second vacuum chamber 3;

[0043] The interior of the second vacuum chamber 3 is connected to the interior of the first vacuum chamber 2 through a partition mechanism 5, the output end of the vacuum mechanism 4 passes through the device body 1 and the top of the second vacuum chamber 3 to communicate with the interior of the second vacuum chamber 3, and the output end of the feeding mechanism 6 passes through the device body 1 and the top of the second vacuum chamber 3 to communicate with the interior of the molding mechanism 7;

[0044] The molding mechanism 7 includes a pouring bin 71, a transmission connection column 710 and a limiting sleeve 712. The pouring bin 71 is rotatably mounted at the bottom of the second vacuum bin 3, and the limiting sleeve 712 is fixedly mounted at the top of the second vacuum bin 3. The limiting sleeve 712 is slidably mounted with the transmission connection column 710. When the pouring bin 71 slides inside the limiting sleeve 712, it can drive the pouring bin 71 to rotate inside the second vacuum bin 3.

[0045] The vacuum mechanism 4 can evacuate the interior of the first vacuum chamber 2 and the second vacuum chamber 3, the separation mechanism 5 can control the connection between the interior of the second vacuum chamber 3 and the interior of the first vacuum chamber 2, the feeding mechanism 6 can inject the infusion raw material into the interior of the molding mechanism 7, and when the raw material inside the molding mechanism 7 gradually increases, it can drive the transmission connecting column 710 to move upward inside the limiting sleeve 712, and when the transmission connecting column 710 moves upward inside the limiting sleeve 712, it can drive the infusion chamber 71 to rotate inside the second vacuum chamber 3.

[0046] Before the infusion operation, the carbon fiber and the resin matrix must be mixed in a certain proportion to form an infusion raw material which is stored in the feeding mechanism 6. When the infusion operation is performed, the first vacuum chamber 2 and the second vacuum chamber 3 are first evacuated by the vacuum mechanism 4, and then the first vacuum chamber 2 and the second vacuum chamber 3 are separated by the separation mechanism 5. Then, the infusion raw material is poured into the infusion chamber 71 by the feeding mechanism 6. When the infusion raw material in the infusion chamber 71 gradually increases, the transmission connecting column 710 can be driven to move upward. When the transmission connecting column 710 moves upward inside the limiting sleeve 712, it can drive the infusion chamber 71 to rotate inside the second vacuum chamber 3. When the infusion chamber 71 rotates, the position of the feeding mechanism 6 remains unchanged, which can make the directions of carbon fibers in different layers of the carbon fiber sheet intertwine with each other during the infusion process, thereby increasing the overall strength of the carbon fiber sheet and preventing the carbon fiber sheet from cracking along the direction of the carbon fiber during use.

[0047] Example 2

[0048] The difference from the above embodiment is that, please refer to Figure 1 - Figure 5 The vacuum mechanism 4 includes a vacuum pump 41, a vacuum tube 42 and a vacuum joint 43. The vacuum pump 41 is fixedly installed on the side of the device body 1, and the vacuum joint 43 is fixedly installed on the top inside the second vacuum chamber 3. One end of the vacuum tube 42 is fixedly connected to the output end of the vacuum pump 41, and the other end of the vacuum tube 42 passes through the device body 1 and the top of the second vacuum chamber 3 and is fixedly connected to the vacuum joint 43.

[0049] The separation mechanism 5 includes a connecting pipe 51, which is fixedly installed inside the side wall of the second vacuum chamber 3, a mounting seat 52 is fixedly installed inside the connecting pipe 51, a separation spring 53 is fixedly connected to one side of the mounting seat 52, a separation block 54 is fixedly connected to the movable end of the separation spring 53, a separation connecting rod 55 is slidably installed inside the mounting seat 52, a separation card block 56 is fixedly installed outside the separation connecting rod 55, and a separation handle 57 is fixedly connected to one end of the separation connecting rod 55;

[0050] One end of the separation connecting rod 55 is rotatably connected to the separation block 54 , and the other end of the separation connecting rod 55 is fixedly connected to the separation handle 57 .

[0051] One end of the separation connecting rod 55 passes through the side wall of the device body 1 and is fixedly connected to the separation handle 57. The separation connecting rod 55 is clamped with the side wall of the device body 1 through the external separation clamping block 56. When the separation connecting rod 55 moves, it can drive the separation block 54 to move synchronously.

[0052] The outer diameter of the partition block 54 is the same as the diameter of the inner wall of the connecting pipe 51 . When the partition block 54 moves into the connecting pipe 51 , the inner wall of the connecting pipe 51 can be blocked.

[0053] Before the perfusion operation is performed, the first vacuum chamber 2 and the second vacuum chamber 3 are closed. At this time, the separation block 56 is engaged with the inner side wall of the device body 1, and the separation block 54 is located outside the connecting pipe 51. The first vacuum chamber 2 and the second vacuum chamber 3 are connected through the connecting pipe 51. Then, the vacuum pump 41 is started to evacuate the inside of the first vacuum chamber 2 and the second vacuum chamber 3 through the vacuum pipe 42 and the vacuum joint 43. After the first vacuum chamber 2 and the second vacuum chamber 3 are evacuated, the separation handle 57 is pulled. The separation handle 57 is pulled and rotated. When the separation handle 57 is rotated, the separation block 56 is rotated and engaged with the outer side of the device body 1. When the separation handle 57 is pulled, the separation block 54 can be driven to move to the inside of the connecting pipe 51. At this time, the separation spring 53 contracts, and the separation block 54 moves to the inside of the connecting tube 51 to seal the connecting tube 51, thereby separating the first vacuum chamber 2 and the second vacuum chamber 3. When vacuum infusion is carried out inside the second vacuum chamber 3, if any of the first vacuum chamber 2 and the second vacuum chamber 3 has poor sealing, the inside of the second vacuum chamber 3 can be kept in a vacuum state, thereby ensuring the production quality of vacuum infusion. After the infusion is completed, the first vacuum chamber 2 is opened and the separation handle 57 is rotated. When the separation handle 57 rotates, it drives the separation block 56 to rotate and no longer engages with the outside of the device body 1. At this time, the separation spring 53 rebounds and drives the separation block 54 to move to the outside of the connecting tube 51, so that the first vacuum chamber 2 and the second vacuum chamber 3 are restored to be connected.

[0054] Example 3

[0055] The difference from the above embodiment is that, please refer to Figure 2 - Figure 7 The feeding mechanism 6 includes a storage bin 61, a feeding pipe 62 and a fixed connecting pipe 63. The storage bin 61 is fixedly installed on the outside of the device body 1, and the fixed connecting pipe 63 is fixedly installed on the top of the second vacuum bin 3. One end of the feeding pipe 62 is connected to the discharge end of the storage bin 61, and the other end of the feeding pipe 62 passes through the device body 1 and the top of the second vacuum bin 3 and is fixedly connected to the fixed connecting pipe 63. A sliding connecting pipe 66 is slidably installed on the outside of the fixed connecting pipe 63, and a discharge port 67 is fixedly connected to the bottom of the sliding connecting pipe 66. A block connecting frame 64 is fixedly installed on the inside of the fixed connecting pipe 63, and a sealing block 65 is fixedly connected to the bottom of the block connecting frame 64.

[0056] The inner side of the sliding connection pipe 66 is slidably mounted on the outside of the fixed connection pipe 63, and the outer side of the sliding connection pipe 66 is connected to the molding mechanism 7. The filling material in the storage bin 61 passes through the feeding pipe 62, the fixed connection pipe 63 and the sliding connection pipe 66 and then enters the molding mechanism 7 through the discharge port 67.

[0057] The sealing block 65 is fixedly installed at the bottom of the fixed connecting tube 63 through the block connecting frame 64. The outer diameter of the sealing block 65 is the same as the inner diameter of the discharge port 67. The inner diameter of the sliding connecting tube 66 is larger than the outer diameter of the sealing block 65. When the sliding connecting tube 66 moves up and down outside the fixed connecting tube 63, it can drive the discharge port 67 to move synchronously.

[0058] When the filling operation is performed, the filling material enters the fixed connecting pipe 63 from the inside of the storage bin 61 along the feeding pipe 62, and then enters the inside of the filling bin 71 through the sliding connecting pipe 66 and the discharge port 67. When the filling material in the filling bin 71 gradually increases, the position of the filling turntable 74 rises. When the position of the filling turntable 74 rises, it can drive the sliding connecting pipe 66 to move upward outside the fixed connecting pipe 63, so that the filling operation can be performed layer by layer. When the filling turntable 74 moves to the highest point, the sealing block 65 is located inside the discharge port 67 and seals the bottom of the discharge port 67. The height of the discharge port 67 can be adjusted according to the height of the filling material in the filling bin 71 at any time during the filling process, and the filling port can be sealed in time after the filling is completed to prevent excess filling material from entering the filling bin 71, which can effectively prevent bubbles from appearing inside the filling material during the filling process and improve the filling quality.

[0059] Example 4

[0060] The difference from the above embodiment is that, please refer to Figure 6-Figure 9The molding mechanism 7 includes a pouring bin 71, a card block sliding seat 76 and a limiting sleeve 712. The pouring bin 71 is rotatably mounted at the bottom of the second vacuum bin 3, and the limiting sleeve 712 is fixedly mounted on the top of the second vacuum bin 3. The upper mounting plate 72 is slidably mounted inside the pouring bin 71, and a pouring molding plate 73 is slidably mounted inside the pouring bin 71. A pouring turntable 74 is rotatably mounted inside the pouring molding plate 73, and a transmission ring 75 is fixedly mounted inside the upper mounting plate 72. The card block sliding seat 76 is rotatably mounted on the top of the pouring turntable 74. A transmission card block 77 is slidably mounted on the top of the card block sliding seat 76. A card block spring 78 is fixedly connected to the inner side of the transmission card block 77. A connecting column fixing seat 79 is fixedly mounted on the top of the connecting column fixing seat 79. A transmission connecting column 710 is fixedly connected to the top of the connecting column fixing seat 79. A limiting card block 711 is fixedly mounted on the outside of the transmission connecting column 710, and a limiting sliding groove 713 is provided inside the limiting sleeve 712.

[0061] The exterior of the sliding connection tube 66 is fixedly connected to the interior of the pouring dial 74 .

[0062] The bottom of the connecting column fixing seat 79 is a hollow structure. Two transmission blocks 77 are slidably installed on the top of the block sliding seat 76. The inner sides of the two transmission blocks 77 are connected to each other through the connecting column fixing seat 79 via the block spring 78. The outer sides of the transmission blocks 77 are engaged with the transmission ring 75. The width of the bottom opening of the connecting column fixing seat 79 is greater than the width of the forming mechanism 7.

[0063] When the transmission block 77 contacts the sliding connection tube 66 , the transmission block 77 can be retracted toward the inner side of the connection column fixing seat 79 .

[0064] The outer portion of the transmission connection column 710 is engaged with the limiting slide groove 713 inside the limiting sleeve 712 through the limiting clamping block 711. When the transmission connection column 710 moves up and down, the limiting clamping block 711 can move along the limiting slide groove 713 to drive the connection column fixing seat 79 to rotate. When the connection column fixing seat 79 rotates, the clamping block sliding seat 76 can be driven to rotate. When the clamping block sliding seat 76 rotates, the upper mounting plate 72 can be driven to rotate through the transmission clamping block 77 and the transmission ring 75. When the upper mounting plate 72 rotates, the filling bin 71 can be driven to rotate.

[0065] The perfusion turntable 74 is fixedly mounted on the outside of the sliding connection tube 66 , and the bottom of the perfusion turntable 74 is flush with the bottom of the sliding connection tube 66 .

[0066] When the filling material inside the filling bin 71 increases during the filling operation, the upper mounting plate 72, the filling forming plate 73 and the filling turntable 74 can be driven to move upward synchronously. When the filling turntable 74 moves upward, the block sliding seat 76 can be driven to move synchronously. When the block sliding seat 76 moves upward, the transmission connecting column 710 can be driven to slide inside the limiting sleeve 712 through the connecting column fixing seat 79. When the transmission connecting column 710 slides inside the limiting sleeve 712, the limiting block 711 can slide along the limiting slide groove 713 to drive the transmission connecting column 710 to rotate. When the transmission connecting column 710 rotates, it can be fixed by the connecting column The seat 79 drives the block sliding seat 76 to rotate, and when the block sliding seat 76 rotates, it can drive the transmission block 77 to rotate. When the transmission block 77 rotates, it can drive the upper mounting plate 72 through the transmission ring 75, thereby driving the filling bin 71 to rotate as a whole. When the filling bin 71 rotates, the filling turntable 74 is fixedly connected to the discharge port 67 and does not rotate with the filling bin 71. When the filling bin 71 rotates, the filling raw material enters the inside of the filling bin 71 from the fixed discharge port 67, which can make the directions of the carbon fiber layers of the successfully filled plate staggered, thereby increasing the overall strength of the carbon fiber plate and effectively preventing the carbon fiber plate from cracking during use and processing.
