Description

Technical Field

[0001] The utility model relates to the technical field of ultraviolet UV curing, in particular to an ultraviolet UV curing device. Background Art

[0002] Curing generally refers to the curing conditions or requirements of coatings (paints), inks, adhesives (glue) or other potting sealants that need to be cured by ultraviolet light, which is different from heating curing, crosslinking agent (curing agent) curing, natural curing, etc.

[0003] According to an ultraviolet UV curing device disclosed in announcement number CN218013893U, it includes a workbench, and a frame is arranged on the top of the workbench; by placing the workpiece on the connecting seat, the first rack and the second rack respectively drive the first clamping plate and the second clamping plate installed on the first connecting plate and the second connecting plate to move toward the workpiece, clamp and fix the workpiece, and through the action of the driven gear, the connecting column drives the clamping assembly and the workpiece to rotate.

[0004] The above-mentioned document clamps the workpiece from two sides by means of two plate-shaped first clamping plates and second clamping plates when limiting the position of the workpiece. However, different application scenarios result in different specifications of the workpiece, and the plate-shaped first clamping plates and second clamping plates can only limit workpieces of one specification. This results in that when the curing equipment encounters a workpiece with a cylindrical structure, it is difficult for the first clamping plates and the second clamping plates to fit the workpiece together, thereby affecting the stability of the curing equipment. After the workpiece is limited, the rotation of the connecting column drives the clamping assembly and the workpiece to be limited. However, the rotation of the clamping assembly cannot flip the workpiece, which results in that the ultraviolet lamp can only cure one side of the workpiece, thereby affecting the curing efficiency of the workpiece. Utility Model Content

[0005] The utility model aims to solve the problem that the curing equipment in the prior art can only clamp workpieces of one specification, and proposes an ultraviolet UV curing device.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A UV curing device comprises a curing device, which comprises an operating table, a frame, a conveyor belt, a workbench, and a curing end head. A motor is fixedly mounted on the frame, and a rotating shaft 1 is fixedly connected to the output end of the motor. A rotating shaft 2 is rotatably mounted on the frame. Limit blocks are fixedly mounted on the rotating shaft 1 and the rotating shaft 2, and a moving rod is installed in the limiting block. A bracket is fixedly mounted on the moving rod, and a clamping plate for supporting a workpiece is fixedly mounted on the bracket. A pressure plate for applying pressure to the workpiece is connected to the bracket through a moving part.

[0008] Preferably, the first rotating shaft is horizontally arranged corresponding to the second rotating shaft, and the moving rod is horizontally arranged.

[0009] Preferably, a slot corresponding to the moving rod is formed on the limit block, and a locking bolt corresponding to the moving rod is threadedly connected to the limit block.

[0010] Preferably, the moving part comprises a screw rod rotatably mounted on the bracket, and a matching nut is provided on the sliding sleeve of the screw rod, and the pressure plate is provided on the nut.

[0012] Preferably, the clamping plate and the pressure plate are arranged above the workbench, and the clamping plate and the pressure plate are plate-shaped or arc-shaped structures that are compatible with the workpiece.

[0013] Compared with the prior art, the utility model has the following advantages:

[0014] 1. The utility model selects the specifications of the clamping plate and the pressure plate so that the clamping plate and the pressure plate can limit workpieces of different specifications, thereby increasing the contact degree between the clamping plate, the pressure plate and the workpiece, so that the workpiece can maintain a certain stability during processing.

[0015] 2. The utility model provides corresponding rotating shaft 1 and rotating shaft 2 on the frame. When the clamping plate and the pressure plate limit the workpiece, the rotating shaft 1 is driven to rotate by the motor, and the rotating shaft 1 drives the rotating shaft 2 to rotate through the workpiece, so that the rotating shaft 1 and the rotating shaft 2 can drive the workpiece to rotate evenly during rotation, and then the curing end can evenly cure the workpiece, effectively improving the efficiency of curing the workpiece.
