DETAILED DESCRIPTION

[0034] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The UV curing device and method involved in the present invention are not limited to the various structures described in the following embodiments. All other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0035] like Figure 1-7 As shown, in one embodiment, a UV curing device is proposed, including a base 1, a housing 101 is installed on the upper end of the base 1, a conveying assembly 2 is arranged on the front and rear sides of the housing 101, a flip assembly 3 is arranged in the base 1, the flip assembly 3 includes a clamping mechanism 31, a flipping mechanism 32 and a transfer mechanism 33, the clamping mechanism 31 includes a guide rod 311, a connecting seat 312, a rotating frame 314, a flip frame 316, a sliding rod 317, a tension spring 319, a clamping shell 318 and a top rod 3110, a plurality of guide rods 311 are slidably connected in the base 1, the connecting seat 312 is installed on the upper end of the guide rod 311, an output end of an electric push rod 313 installed at the lower end of the base 1 is fixedly connected to the connecting seat 312, and the rotating frame 314 is installed on the upper end of the connecting seat 312 A connecting shaft 315 is rotatably connected in the rotating frame 314, and the flip frame 316 is installed between the connecting shafts 315. Two sets of slide bars 317 are respectively installed on the upper and lower sides of the flip frame 316. A pair of clamping shells 318 are slidably connected on the circumferential surface of the slide bars 317. Multiple tension springs 319 are installed between the clamping shells 318 and the flip frame 316. Multiple push rods 3110 are slidably connected in the base 1, and the push rods 3110 are used to lift the clamping shells 318 located above; the flipping mechanism 32 includes a servo motor 321, a drive shaft 322 and a first sprocket group 323. The servo motor 321 is installed in the rotating frame 314, and the drive shaft 322 is installed at the output end of the servo motor 321. The drive shaft 322 is connected to the connecting shaft 315 through the first sprocket group 323.

[0036] When the embodiment of the present invention is actually used, the material to be cured is placed on the conveying component 2, and the ultraviolet lamp 102 on the front side will first cure the upper part of the material, and then the material will move to the flip component 3. At this time, the clamping shell 318 located at the top can be lifted up by the action of the top rod 3110, so that enough space can be left between the clamping shells 318 on the upper and lower sides, and the material can be moved to the clamping shell 318 located at the bottom. At this time, the electric push rod 313 can be controlled to operate, and the electric push rod 313 will push the connecting seat 312 and the rotating frame 314 upward to move upward, and the two clamping shells 318 will move upward to separate the upper clamping shell 318 from the top rod 3110. At this time, the clamping shells 318 on the upper and lower sides can be pulled together by the action of the tension spring 319 and the sliding rod 317. The servo motor 321 is controlled to operate, and the servo motor 321 controls the connecting shaft 315 to rotate one hundred and eighty degrees under the action of the driving shaft 322 and the first sprocket, thereby driving the turning frame 316 and the upper and lower clamping shells 318 to rotate at the same time, so that the material can stably complete the direction flipping, and then the electric push rod 313 is controlled to retract and reset, so that the turning frame 316 and the clamping shell 318 are lowered and reset. When the clamping shells 318 on the upper and lower sides are lowered and reset, during the reset process of the lower clamping shell 318, the push rod 3110 will lift the upper clamping shell 318 again, and release the clamping fixation of the material after the material flips direction. After the lower clamping shell 318 is completely reset, the material can be continuously transported under the action of the transfer mechanism 33 to complete the solidification effect on the other side.

[0037] In one case of an embodiment of the present invention, since the two clamping shells 318 are respectively arranged on the upper and lower sides of the flip frame 316, when the flip frame 316 rotates, the two clamping shells 318 will be driven to flip directions at the same time, and the clamping shell 318 originally located at the upper side and the clamping shell 318 originally located at the lower side will swap positions.

[0038] like Fig.10 As shown, as a preferred embodiment of the present invention, limit rods 3111 are installed on both the upper and lower sides of the clamping shell 318, and the limit rods 3111 are used to limit the position of the clamping shell 318 located below.

[0039] When the embodiment of the present invention is actually used, the clamping shells 318 can be pulled closer to each other under the action of the tension spring 319. At this time, the upward movement position of the lower clamping shell 318 is restricted by the action of the limit rod 3111, so that the transfer mechanism 33 in the lower clamping shell 318 can maintain a high degree of alignment with the conveying component 2, which is convenient for the transfer of materials.

[0040] like Figure 7 and 8As shown, as another preferred embodiment of the present invention, a plurality of through grooves 4 and telescopic grooves 401 are provided in the clamping shell 318, the telescopic grooves 401 are connected to the through grooves 4, the telescopic grooves 401 are slidably connected with inclined blocks 402, a first spring 403 is installed between the inclined blocks 402 and the telescopic grooves 401, and the top rod 3110 is slidably connected with the through grooves 4.

[0041] When the embodiment of the present invention is actually used, under the action of the first spring 403, the first spring 403 will push the inclined block 402 to extend out of the telescopic slot 401. When the two clamping shells 318 clamp the material and flip the direction, during the descending process, the push rod 3110 will first push the inclined block 402 to retract, and then pass through the through slot 4 opened on the surface of the lower clamping shell 318, and then will support the inclined block 402 in the upper clamping shell 318, so that the position of the upper clamping shell 318 cannot be lowered, thereby achieving the effect of lifting the upper clamping shell 318 after the lower clamping shell 318 descends and resets, leaving space between the clamping shells 318 to facilitate the entry and exit of materials.

[0042] like Figure 2 , 7 As shown in Figures 9 and 9, as another preferred embodiment of the present invention, a rotating base 5 is installed at the lower end of the base 1, and a gear 501 is rotatably connected inside the rotating base 5. A first tooth groove 502 is opened on the surface of the guide rod 311, and a second tooth groove 503 is opened on the surface of the top rod 3110, and the gear 501 is meshed with the first tooth groove 502 and the second tooth groove 503.

[0043] When the embodiment of the present invention is actually used, when the electric push rod 313 drives the connecting seat 312 to move upward, it will also drive the guide rod 311 to move upward. At this time, under the action of the gear 501, the first tooth groove 502 provided on the surface of the guide rod 311 will drive the gear 501 to rotate. After the gear 501 rotates, the gear 501 will drive the position of the push rod 3110 to drop under the action of the second tooth groove 503. When the material is flipped, the position of the push rod 3110 is controlled to drop to avoid motion interference caused by the push rod 3110 when the clamping shell 318 rotates, and at the same time reduce the space range required for the material flipping movement. On the contrary, when the clamping shell 318 below is lowered and reset, the push rod 3110 will move upward to lift the clamping shell 318 above, thereby releasing the clamping effect on the material.

[0044] like Fig.10 and 11 As shown, as another preferred embodiment of the present invention, the transfer mechanism 33 includes a connecting rod 331, a connecting roller 332 and a connecting belt 333, the connecting rod 331 is rotatably connected in the clamping shell 318, the connecting roller 332 is installed on the circumferential surface of the connecting rod 331, and the connecting belt 333 is connected between the connecting rollers 332.

[0045] When the embodiment of the present invention is actually used, the connecting rod 331 is controlled to rotate under the action of the transfer mechanism 33, and the connecting rod 331 will drive the connecting roller 332 to rotate, and the connecting roller 332 will drive the connecting belt 333 to rotate. In cooperation with the conveying component 2, the material can be transferred to the connecting belt 333. When the clamping shells 318 on the upper and lower sides clamp the material to flip the direction, it will not affect the position of the uncured side of the material. At the same time, after the material is flipped, the material can be stably moved to the conveying component 2 to cure the other side of the material.

[0046] like Figure 3 and 12 As shown, as another preferred embodiment of the present invention, a plurality of guide shafts 504 are slidably connected in the machine base 1, a connecting plate 505 is installed at the upper end of the guide shaft 504, a second spring 506 is installed between the connecting plate 505 and the machine base 1, a connecting frame 507 is installed at the upper end of the connecting plate 505, a rotating rod 508 and a driven shaft 509 are rotatably connected in the connecting frame 507, the rotating rod 508 is connected to the output end of the driving motor 5010 installed at the upper end of the connecting plate 505, the rotating rod 508 and the driven shaft 509 are connected via a second sprocket set 5011, a first friction wheel 5012 is installed on the circumferential surface of the driven shaft 509, and a second friction wheel 5013 is installed on the circumferential surface of the connecting rod 331.

[0047] When the embodiment of the present invention is actually used, when the clamping shell 318 below is reset, the second friction wheel 5013 located below will fit with the first friction wheel 5012, and at the same time, through the action of the guide shaft 504 and the second spring 506, the first friction wheel 5012 and the second friction wheel 5013 are stably fitted together. At this time, by controlling the operation of the drive motor 5010, the drive motor 5010 will drive the rotating rod 508 to rotate, and the rotating rod 508 will drive the driven shaft 509 to rotate under the action of the second sprocket group 5011, and the driven shaft 509 will drive the first friction wheel 5012 to rotate, and the first friction wheel 5012 will drive the second friction wheel 5013 to rotate, thereby achieving the effect of controlling the operation of the transfer mechanism 33 and completing the transfer of materials.

[0048] like Figure 1 and 3 As shown, as another preferred embodiment of the present invention, the conveying assembly 2 includes a conveying rod 201, a conveying roller 202 and a conveying belt 203. The conveying rod 201 is rotatably connected in the housing 101, the conveying roller 202 is installed on the circumferential surface of the conveying rod 201, and the conveying belt 203 is connected between the conveying rollers 202. The conveying belt 203 is flush with the connecting belt 333 located below.

[0049] When the embodiment of the present invention is actually used, by controlling the rotation of the conveying rod 201, the conveying rod 201 will drive the conveying roller 202 to rotate, and the conveying roller 202 will drive the conveyor belt 203 to rotate. When the material is placed on the conveyor belt 203, since the conveyor belt 203 is highly flush with the connecting belt 333 in the transfer mechanism 33, after the solidification treatment on one side of the material is completed, the material will then be transported to the transfer mechanism 33 to complete the effect of material flipping, and finally the material will be transported to the conveying component 2 again through the transfer mechanism 33 to complete the solidification treatment on the other side of the material.

[0050] like Figure 3 and 4 As shown, as another preferred embodiment of the present invention, a pair of ultraviolet irradiation lamps 102 are installed in the housing 101, and the ultraviolet irradiation lamps 102 are respectively located at the front and rear sides of the flip assembly 3.

[0051] In actual application, the embodiment of the present invention is provided with two groups of ultraviolet lamps 102. After curing one side of the material, the material can be turned over after passing through the flipping component 3, and then the other side of the material can be cured, thereby achieving the effect of completing the curing treatment on both sides of the material.

[0052] The present invention also provides a UV curing method, which specifically comprises the following steps:

[0053] Step 1: Place the material to be cured on the conveying component 2, and first cure the upper part of the material through the ultraviolet irradiation lamp 102 on the front side, and then move the material to the flipping component 3 to complete the direction flipping;

[0054] Step 2: After the material moves between the clamping shells 318, the top rod 3110 will lift the upper clamping shell 318 to leave space for the material to enter. When the clamping shell 318 moves upward, the clamping shells 318 on the upper and lower sides can be pulled closer to each other by the action of the tension spring 319 and the slide bar 317 to clamp and fix the material therein;

[0055] Step 3: By controlling the servo motor 321 to operate, the turning frame 316 and the upper and lower clamping shells 318 are driven to rotate simultaneously, so that the material can be turned stably in the direction;

[0056] Step 4: When the clamping shells 318 on the upper and lower sides are lowered and reset, during the reset process of the lower clamping shell 318, the push rod 3110 will lift up the upper clamping shell 318 again, and release the clamping fixation of the material after the material is turned over;

[0057] Step 5: Finally, the material can be stably moved to the conveying component 2 by the action of the transfer mechanism 33 again, and then the other side of the material is cured by the ultraviolet lamp 102 on the rear side.

[0058] Finally, a few points should be explained: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, which may refer to mechanical connection or electrical connection, or internal communication between two components, or direct connection.
