Description

Technical Field

[0001] This utility model relates to the field of carbon fiber plate processing technology, specifically to a surface spraying device for carbon fiber plates. Background Technology

[0002] Fiberboard is made by impregnating and hardening carbon fibers arranged in the same direction with resin to form carbon fiber sheets. It can effectively solve the problems of difficult construction and large amount of work in multi-layer carbon fiber cloth. It has good reinforcement effect and convenient construction. Using high-quality carbon fiber raw materials and good base resin, carbon fiber sheets have good properties such as high tensile strength, corrosion resistance, shock resistance and impact resistance. At present, a spraying process is required in the processing of carbon fiber sheets.

[0003] Authorization announcement number CN110918352B discloses a surface spraying device for carbon fiber sheets. This device primarily controls the position of the spray head through transverse and longitudinal lead screws in the spraying assembly. When the alignment of the transverse and longitudinal lead screws is insufficient, a stepper motor controls the reciprocating rotation of the spray head, increasing the spraying stroke. The device also uses a flipping motor in the clamping assembly to rotate the upper and lower clamping molds, allowing processing on both the upper and lower surfaces of the carbon fiber sheet. The device utilizes the cooperation of an upper pressure plate and a limiting plate, eliminating the need for manual separation of the upper and lower pressure plates, thus saving manpower. However, in actual use, the device still has the following drawbacks:

[0004] The aforementioned patent mainly uses a flipping motor in the clamping assembly to drive the upper and lower clamping molds to flip, so that both the upper and lower surfaces of the carbon fiber sheet can be processed. However, when clamping and flipping the carbon fiber sheet, multiple drive structures are required to position the sheet, which not only increases the consumption of structural driving force and cost, but also makes it difficult to calibrate and fix the carbon fiber sheet within the clamping structure when loading and unloading the sheet, and it is also difficult to detach the sheet from the clamping structure, increasing the difficulty and inconvenience of loading and unloading the sheet. Furthermore, when performing spraying operations on the surface of the sheet, existing spraying is usually fixed. When dealing with larger carbon fiber sheets, the spraying structure prioritizes the area to be sprayed, which can easily lead to uneven local spraying of the sheet and affect the quality of the finished carbon fiber sheet. Utility Model Content

[0005] The purpose of this invention is to provide a surface coating device for carbon fiber plates to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a surface spraying device for carbon fiber plates, comprising a frame, wherein a first servo motor and a positioning adjustment mechanism are respectively provided on one side of the frame, an electric push rod and an auxiliary positioning mechanism are respectively provided on the other side of the frame, and a horizontal displacement component is provided on the top of the frame;

A pressing rod is sleeved on one end of the mounting base, and a connecting plate is provided on one end of the pressing rod, and the connecting plate is movably connected to the movable rod.

[0009] Preferably, the horizontal displacement component includes a top plate, which is disposed on the top of the frame. A second servo motor is provided at the bottom of one side of the top plate. A first gear is provided at the output end of the second servo motor. A threaded shaft is sleeved on one side inside the top plate. A second gear that meshes with the first gear is provided on one side outside the threaded shaft. A matching moving block is provided on the outside of the threaded shaft. A spraying mechanism is provided at the bottom of the moving block.

[0010] Preferably, the spraying mechanism includes a movable base, which is disposed at the bottom of the movable block. The movable base is equipped with a drive motor, and the output end of the drive motor is provided with an incomplete gear. A through groove is opened at the bottom of the movable base, and guide grooves are opened on both sides of the inner side of the through groove. An internal gear plate is slidably disposed on the inner side of the two guide grooves. The internal gear plate meshes with the incomplete gear. A connecting seat is provided at the bottom of the internal gear plate, and a spraying head is provided at the bottom of the connecting seat.

[0011] Preferably, the bottom of the inner side of the frame is provided with a rotating seat, and the rotating seat is provided with a placement platform. The inner side of the placement platform is provided with a groove to facilitate the storage of the sprayed carbon fiber board and to facilitate the handling of multiple fiber boards.

[0012] Preferably, the top of the bidirectional threaded rod extends out of the U-shaped seat and is provided with a throttle. The U-shaped seat is provided with a protective shell, which covers the outside of the throttle, thereby increasing the operability and protective effect of the structure.

[0013] Preferably, the positioning adjustment mechanism and the auxiliary positioning mechanism are on the same horizontal plane and opposite each other. The first clamping block and the second clamping block are L-shaped structures. The L-shaped clamping blocks facilitate the inner side of the L-shaped clamping blocks to abut against the side of the carbon fiber plate, thereby stably positioning the plate.

[0014] Preferably, a hidden groove is provided on one side of the top plate, and the spraying mechanism is housed inside the hidden groove. By setting the hidden groove, the spraying mechanism is housed in it when loading and unloading the carbon fiber plate, thereby avoiding obstruction during the loading and unloading of the plate.

[0016] The surface coating device for carbon fiber plates proposed in this utility model has at least the following beneficial effects:

[0017] 1. Through the structural cooperation of the first servo motor and the auxiliary positioning mechanism, an active clamping structure and an auxiliary clamping structure can be formed respectively. The first servo motor drives the positioning adjustment mechanism to rotate, thereby flipping and adjusting the carbon fiber plate for double-sided spraying adjustment. The electric push rod is used to move the auxiliary positioning mechanism horizontally to adjust and fix the carbon fiber plate according to different lengths. This causes the carbon fiber plate to be finally fixed under the elastic structure of the two sets of first clamping blocks in the positioning adjustment mechanism and the two sets of second clamping blocks in the auxiliary positioning mechanism, so that the carbon fiber plate is sprayed in a horizontal state. When the sprayed carbon fiber plate is unloaded, the fiber plate can be rotated to a vertical state so that the fixing force of the bidirectional threaded rod on the first clamping block can be slightly loosened to remove the plate. With the first and second clamping blocks in a vertical state, it is convenient to insert the next set of plates into the fixed structure for calibration and positioning, improving the convenience of loading and unloading the carbon fiber plate and the stability in the horizontal placement state.

[0018] 2. Through the structural cooperation of the horizontal displacement component and the spraying mechanism, the spraying mechanism can be moved horizontally under the adjustment of the horizontal displacement component, so that the spraying structure can move and spray on the surface of the fiberboard. During this process, the structural meshing of the incomplete gear and the internal gear plate is used to make the connecting seat move back and forth in the through groove, so that the multiple spraying heads can spray the surface of the carbon fiber board more evenly and comprehensively, avoiding uneven local spraying on the surface of the carbon fiber board, which would affect the finished quality of the board.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0027] Please see Figure 1-6 The present invention provides an embodiment of a surface spraying device for carbon fiber plates, comprising a frame 1, a first servo motor 2 and a positioning adjustment mechanism 3 respectively on one side of the frame 1, an electric push rod 4 and an auxiliary positioning mechanism 5 respectively on the other side of the frame 1, and a horizontal displacement component 6 on the top of the frame 1.

[0028] The positioning adjustment mechanism 3 includes a U-shaped seat 31, which is located at the output end of the first servo motor 2. A bidirectional threaded rod 32 is sleeved on the inner side of the U-shaped seat 31, and a matching first clamping block 33 is symmetrically arranged on the outer side of the bidirectional threaded rod 32. A limiting groove 34 is opened on one side of the inner side of the bidirectional threaded rod 32, and the two first clamping blocks 33 are limited and engaged with the limiting groove 34.

[0029] The auxiliary positioning mechanism 5 includes a turntable 51, which is connected to the output end of the electric push rod 4. A mounting base 52 is provided on one side of the turntable 51. A guide rod 53 is provided on the inner side of the mounting base 52. Springs 54 and second clamping blocks 55 are symmetrically provided on the outer side of the guide rod 53. A hinge seat 56 is provided on one side of the two second clamping blocks 55. A movable rod 58 is provided on the outer side of the hinge seat 56. A pressing rod 57 is sleeved on one end of the mounting base 52. A connecting plate is provided on one end of the pressing rod 57. The connecting plate is movably connected to the movable rod 58.

[0030] The positioning adjustment mechanism 3 and the auxiliary positioning mechanism 5 are on the same horizontal plane and face each other. The two first clamping blocks 33 and the second clamping block 55 are L-shaped structures. The L-shaped clamping blocks make it easy for the inner side of the L-shaped clamping blocks to abut against the side of the carbon fiber plate, thereby stabilizing the plate.

[0031] The horizontal displacement component 6 includes a top plate 61, which is set on the top of the frame 1. A second servo motor 62 is provided on the bottom of one side of the top plate 61. A first gear 63 is provided at the output end of the second servo motor 62. A threaded shaft 65 is sleeved on one side inside the top plate 61. A second gear 64 that meshes with the first gear 63 is provided on one side outside the threaded shaft 65. A matching moving block 66 is provided on the outside of the threaded shaft 65. A spraying mechanism 7 is provided at the bottom of the moving block 66.

[0032] The spraying mechanism 7 includes a movable base 71, which is located at the bottom of the movable block 66. A drive motor 72 is mounted on the movable base 71, and an incomplete gear 73 is mounted at the output end of the drive motor 72. A through groove 78 is opened at the bottom of the movable base 71, and guide grooves 74 are opened on both sides of the inner side of the through groove 78. An internal gear plate 75 is slidably mounted on the inner side of the two guide grooves 74. The internal gear plate 75 meshes with the incomplete gear 73. A connecting seat 76 is located at the bottom of the internal gear plate 75, and a spraying head 77 is located at the bottom of the connecting seat 76. The incomplete gear 73 slides horizontally inside the through groove 78. Multiple sets of spraying heads 77 are provided, and the multiple sets of spraying heads 77 are vertically downward and arranged inside the connecting seat 76, which facilitates the reciprocating movement of multiple sets of spraying heads 77 and improves the uniformity of spraying.

[0033] A hidden groove is provided on one side of the top plate 61. The spraying mechanism 7 is housed inside the hidden groove. By setting the hidden groove, the spraying mechanism 7 is housed in it when loading and unloading the carbon fiber plate, thereby avoiding the loading and unloading of the plate.

[0034] Example 1, as Figure 1-2As shown, a rotating seat is provided at the bottom of the inner side of the frame 1, and a placement platform is provided on the rotating seat. The inner side of the placement platform is provided with a groove. By setting the rotating seat and the placement platform on the bottom surface of the frame 1, the placement platform is made to rotate on the rotating seat. When the plate is being picked up, by making the clamping structures of the two sets of first clamping blocks 33 and second clamping blocks 55 perpendicular, the carbon fiber plate can be made to fall into the groove in the placement platform after contacting the clamping and fixing of the first clamping block 33. Under the rotation adjustment of the structure, multiple carbon fiber plates can be accommodated. After accommodating multiple carbon fiber plates, the placement platform can be removed from the rotating seat for the handling of the carbon fiber plates.

[0035] Example 2, as Figure 1-3 As shown, the top of the bidirectional threaded rod 32 extends out of the U-shaped seat 31 and is equipped with a throttle. The U-shaped seat 31 is equipped with a protective shell, which covers the outside of the throttle. By setting a protective shell on the rotating structure of the U-shaped seat 31, the spraying structure of the spraying mechanism 7 is protected from being covered by the bidirectional threaded rod 32. This prevents the operator from contacting the spray coating adhering to the surface of the bidirectional threaded rod 32 when manually rotating it, thus increasing the protectiveness of the structure.

[0036] Working principle: This is used in the surface coating device for carbon fiber plates;

[0037] When the carbon fiber plate is being sprayed, the two sets of first clamping blocks 33 of the positioning adjustment mechanism 3 and the two sets of second clamping blocks 55 of the auxiliary positioning mechanism 5 can be rotated to a vertical state. At this time, the carbon fiber plate can be vertically inserted into the clamping structure of the two sets of first clamping blocks 33 and second clamping blocks 55. When the carbon fiber plate contacts the second clamping block 55, the second clamping block 55 can be adjusted to adapt to the width of the carbon fiber plate through the elastic connection of the two sets of springs 54 and the second clamping block 55, thereby assisting in the positioning of the plate. By rotating the bidirectional threaded rod 32, the two sets of first clamping blocks 33 can be driven to approach each other under the limit of the limiting groove 34, thereby clamping and fixing the plate. Then, by starting the first servo motor 2, the U-shaped seat 31 is driven to rotate, causing the bidirectional threaded rod 32 to drive the carbon fiber plate fixed by the positioning adjustment mechanism 3 and the auxiliary positioning mechanism 5 to rotate and adjust, so that the top and bottom surfaces of the fiber plate can be sprayed respectively.

[0038] During the spraying operation, the second servo motor 62 is started to drive the first gear 63 and the second gear 64 to mesh, causing the threaded shaft 65 to rotate. Then, the moving block 66 can be horizontally displaced with the rotation of the threaded shaft 65, causing the moving block 66 to drive the spraying mechanism 7 to move on the fixed carbon fiber plate surface. At the same time, the start of the drive motor 72 drives the incomplete gear 73 to rotate, causing the incomplete gear 73 to mesh with the internal gear plate 75, allowing the internal gear plate 75 to move horizontally back and forth inside the two sets of guide grooves 74. This causes the internal gear plate 75 and the spraying head 77 at the bottom of the connecting seat 76 to move back and forth, so that the spraying head 77 can spray the carbon fiber plate comprehensively under the action of back and forth movement and the horizontal movement of the horizontal displacement component 6, improving the uniformity and efficiency of spraying.

[0039] After both sides of the carbon fiber plate are coated, the plate can be adjusted to a vertical state by rotating the first servo motor 2. By canceling the clamping and positioning of the bidirectional threaded rod 32 and the two sets of first clamping blocks 33, the fixation on one side of the plate can be released, causing one side of the plate to tilt downward. By pressing the pressing rod 57, the two sets of movable rods 58 and hinge seats 56 can be moved, causing the two sets of hinge seats 56 to drive the second clamping block 55 to elastically extend and retract outside the guide rod 53, so as to cancel the fixation on the other side of the carbon fiber plate, thereby stabilizing the plate feeding. Then, the carbon fiber plate to be coated is reloaded, and this process is repeated to achieve high-precision and high-efficiency carbon fiber plate coating.
