[0048] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0049] See also Figures 1-4 The utility model provides the following technical solutions: a composite density board curing device, including two belt conveyors 1, a UV light curing mechanism 2 is fixed on the top of the two belt conveyors 1, and also includes: a support platform 3, a turning mechanism 4 and a transfer mechanism 5.

[0050] Further, by Figure 1As shown, in this embodiment, the support platform 3 is located on one side of the belt conveyor 1, and the flip mechanism 4 is fixed on the top of the support platform 3, which is used to drive the density board to flip 180 degrees. The transfer mechanism 5 is fixed on the top of the support platform 3, which is used to transfer the flipped density board to another belt conveyor 1. After adopting the above scheme, when in use, the density board to be cured is placed on the first belt conveyor 1 for transportation, and the UV light curing mechanism 2 is used to cure the density board. After the curing is completed, the density board is moved out of the UV light curing mechanism 2, and then the flip mechanism 4 is used to drive the density board to flip 180 degrees. , and then the flipped density board is transferred to another belt conveyor 1 through the transfer mechanism 5, and the other side of the density board is cured by the UV light curing mechanism 2. After the curing is completed, the density board is transferred to the next workstation on the belt conveyor 1. The utility model is divided into two curing steps. The density board is driven to flip 180 degrees by the set flipping mechanism 4, and the flipped density board is transferred to another belt conveyor 1 by the transfer mechanism 5. There is no need to take out the density board for flipping, and the curing efficiency is greatly improved. The front and back sides of the density board are cured respectively, which improves the product quality.

[0051] It should be noted that the above scheme is only a preferred implementation scheme of the present invention and is not used to limit the present invention. It can be seen from the accompanying drawings that the conveying directions of the two belt conveyors 1 are perpendicular to each other. In actual use, the conveying directions of the two belt conveyors 1 can also be parallel to each other, and the two belt conveyors 1 can be staggered. Therefore, there is no need to set up a transfer mechanism 5, and the flipping requirements can be met to a certain extent.

[0052] Optionally, by Figure 1 and Figure 4 As shown, in this embodiment, the UV light curing mechanism 2 includes: a tunnel box 21, a mounting plate 22, a UV lamp tube 24 and a No. 1 vertical cylinder 25. The tunnel box 21 is fixed to the top of the belt conveyor 1, and an inlet 211 and an outlet 212 are respectively processed at both ends of the tunnel box 21. The mounting plate 22 is located in the tunnel box 21, and the UV lamp tube 24 is fixed to the lower part of the mounting plate 22 by a fixing column 23. The No. 1 vertical cylinder 25 is fixed to the top of the tunnel box 21, and the piston rod of the No. 1 vertical cylinder 25 passes through the tunnel box 21 and is fixedly connected to the mounting plate 22. After adopting the above scheme, when the density board moves to the bottom of the UV lamp tube 24, the No. 1 vertical cylinder 25 is started to push the UV lamp tube 24 downward, so that the UV lamp tube 24 is close to the density board, and then the UV lamp tube 24 is turned on. The UV lamp tube 24 emits ultraviolet light to cure the density board. After curing is completed, the density board continues to be transported.

[0053] Preferably, by Figure 1 and Figure 4As shown, in this embodiment, the UV light curing mechanism 2 also includes: a No. 1 guide column 26, two No. 1 guide columns 26 are symmetrically fixed to the top surface of the mounting plate 22, and the No. 1 guide columns 26 pass through the tunnel box 21. After adopting the above scheme, the two No. 1 guide columns 26 are used to guide the mounting plate 22, thereby improving the stability of the mounting plate 22.

[0054] Preferably, by Figure 1 and Figure 4 As shown, in this embodiment, multiple UV lamp tubes 24 are fixed at equal intervals on the lower part of the mounting plate 22, and each UV lamp tube 24 is fixedly connected to the mounting plate 22 using two symmetrically distributed fixing columns 23. After adopting the above scheme, the utility model adopts a three-UV lamp tube 24 design, which has high curing efficiency.

[0055] Optionally, by Figure 1 and Figure 2 As shown, in this embodiment, the flip mechanism 4 includes: a bearing seat 41, a flip frame 42, a motor fixing plate 43, a servo motor 44, a No. 1 lifting plate 45, a No. 1 vacuum suction cup 46 and a No. 2 vertical cylinder 47. The two bearing seats 41 are fixed at intervals on the top of the support platform 3. The flip frame 42 is rotatably connected between the two bearing seats 41. The motor fixing plate 43 is fixed on the top of the support platform 3. The servo motor 44 is fixed on the motor fixing plate 43 to drive the flip frame 42 to flip. The No. 1 lifting plate 45 is located below the flip frame 42. The No. 1 vacuum suction cup 46 is fixed on the No. 1 lifting plate 45. The No. 2 vertical cylinder 47 It is fixed to the top of the turning frame 42, and the piston rod of the No. 2 vertical cylinder 47 passes through the turning frame 42 and is fixedly connected to the No. 1 lifting plate 45. After adopting the above scheme, when in use, the No. 1 vacuum suction cup 46 is connected to the vacuum pump using a hose. When the density board moves to the bottom of the No. 1 lifting plate 45, the No. 2 vertical cylinder 47 is started, and the No. 2 vertical cylinder 47 drives the No. 1 lifting plate 45 to move downward, so that the No. 1 vacuum suction cup 46 is against the density board, and the vacuum pump is started, and the No. 1 vacuum suction cup 46 is used to suck the density board. Finally, the servo motor 44 is started, and the turning frame 42 is driven to turn by the servo motor 44, so that the density board is turned 180 degrees.

[0056] It should be noted that, as mentioned above, when the conveying directions of the two belt conveyors 1 are parallel to each other, the turning requirement can be met to a certain extent without setting up a transfer mechanism 5. However, if this solution is adopted, after the density board is flipped 180 degrees, the No. 1 vacuum suction cup 46 will be located below the density board, which is inconvenient to place the density board on the belt conveyor 1.

[0057] It should be further explained that, in principle, a single belt conveyor 1 can also meet the work requirements. At this time, the flipping mechanism 4 needs to be set in the tunnel box 21, and there is no need to set the transfer mechanism 5. However, because the density board has a certain length and width, in order to avoid the density board hitting the UV lamp 24 when flipping, it is necessary to increase the height of the tunnel box 21 so that the UV lamp 24 can be lifted to a higher position. However, it is also inconvenient to put the density board back on the belt conveyor 1. By changing the No. 1 vacuum suction cup 46, for example, replacing the No. 1 vacuum suction cup 46 with a pneumatic clamp, although the above problems can be solved, the use effect is not ideal, and the pneumatic clamp needs to be movable in the horizontal and vertical directions, which is more troublesome and inconvenient to operate in the narrow space of the tunnel box 21.

[0058] Preferably, by Figure 1 and Figure 2 As shown, in this embodiment, the flip mechanism 4 also includes: a No. 2 guide column 48, two No. 2 guide columns 48 are symmetrically fixed to the top surface of the No. 1 lifting plate 45, and the No. 2 guide columns 48 pass through the flip frame 42. After adopting the above scheme, the two No. 2 guide columns 48 are used to guide the No. 1 lifting plate 45 to ensure the stability of the No. 1 lifting plate 45.

[0059] Optionally, by Figure 1 and Figure 3 As shown, in this embodiment, the transfer mechanism 5 includes: a fixed frame 51, a horizontal linear module 52, a slide 53, a vertical linear module 54, a lifting frame 55, a second lifting plate 56 and a second vacuum suction cup 57. The fixed frame 51 is fixed to the top of the support platform 3, the horizontal linear module 52 is fixed on the fixed frame 51, the slide 53 is fixed on the slider of the horizontal linear module 52, the vertical linear module 54 is fixed to the bottom of the slide 53, the lifting frame 55 is fixed on the slider of the vertical linear module 54, the second lifting plate 56 is fixed to the bottom end of the lifting frame 55, and the second vacuum suction cup 57 is fixed on the second lifting plate 56. After adopting the above scheme, when in use, the second vacuum suction cup 5 7 Use a hose to connect the vacuum pump. When the density board is flipped 180 degrees, first start the horizontal linear module 52 to move the No. 2 vacuum suction cup 57 to the top of the density board. Then start the vertical linear module 54 to make the No. 2 vacuum suction cup 57 press against the density board, and start the vacuum pump. Use the No. 2 vacuum suction cup 57 to suck the density board. Then start the vertical linear module 54 to lift the density board. Then start the horizontal linear module 52 again to transfer the density board to the top of the second belt conveyor 1. Then start the vertical linear module 54 again to move the density board down close to the belt conveyor 1. Finally, place the density board on the belt conveyor 1 for the second curing. At this time, the No. 2 vacuum suction cup 57 is reset.

[0060] Preferably, by Figure 1As shown, in this embodiment, it also includes: a baffle 11, the baffle 11 is fixed to the top of the belt conveyor 1 and is located behind the discharge port 212. After adopting the above scheme, the baffle 11 is used to position the density board to ensure that the position of the density board when it is against the baffle 11 is just opposite the position of the flip mechanism 4.

[0061] It should be noted that the belt conveyor 1, UV lamp tube 24, vertical cylinder No. 1 25, servo motor 44, vertical cylinder No. 2 47, horizontal linear module 52 and vertical linear module 54 are all conventional commercially available equipment with built-in power switches. Those skilled in the art can make routine selections according to usage needs. Their working principles are common knowledge known to those skilled in the art and have been fully disclosed by the existing technology, so they will not be elaborated on in this article.

[0062] The circuit connection involved in the present invention is a common means used by those skilled in the art, and technical inspiration can be obtained through a limited number of experiments, and it belongs to the widely used existing technology.

[0063] Components not described in detail herein are prior art.

[0064] The working principle and use process of the present invention are as follows: When the curing device of the present invention is used, the density board to be cured is placed on the first belt conveyor 1 for transportation. When the density board moves to the position directly below the UV lamp 24, the first vertical cylinder 25 is started to push the UV lamp 24 downward, so that the UV lamp 24 is close to the density board. Then, the UV lamp 24 is turned on, and the UV lamp 24 emits ultraviolet light to cure the density board. After the curing is completed, the density board continues to be transported.

[0065] After the density board is against the baffle 11, the second vertical cylinder 47 is started, and the first lifting plate 45 is driven downward by the second vertical cylinder 47, so that the first vacuum suction cup 46 is against the density board, and the vacuum pump is started, and the first vacuum suction cup 46 is used to suck the density board. Finally, the servo motor 44 is started, and the servo motor 44 drives the turning frame 42 to turn over, so that the density board is turned 180 degrees.

[0066] Then, the horizontal linear module 52 is started to move the second vacuum suction cup 57 to the top of the density board. Then, the vertical linear module 54 is started to make the second vacuum suction cup 57 press against the density board, and the vacuum pump is started to use the second vacuum suction cup 57 to suck the density board. Then, the vertical linear module 54 is started to lift the density board. Then, the horizontal linear module 52 is started again to transfer the density board to the top of the second belt conveyor 1. Then, the vertical linear module 54 is started again to move the density board down close to the belt conveyor 1. Finally, the density board is placed on the belt conveyor 1 for the second curing. At this time, the second vacuum suction cup 57 is reset.

[0067] After curing is completed, the density board is transferred to the next station on the belt conveyor 1;

[0068] The utility model is divided into two curing processes. The density board is driven to flip 180 degrees by the provided flipping mechanism 4, and the flipped density board is transferred to another belt conveyor 1 by the transfer mechanism 5. There is no need to take out the density board for flipping, and the curing efficiency is greatly improved. In addition, the front and back sides of the density board are cured respectively, thereby improving the product quality.
