Description

Technical Field

[0001] The utility model relates to the technical field of flat-panel UV spray printing processing equipment, in particular to a positioning mechanism for flat-panel UV spray printing processing. Background Art

[0002] Flatbed UV printing is a printing technology that uses UV ink to print directly on the surface of flat materials. UV printing technology combines inkjet printing and UV curing technology. UV ink is sprayed onto the surface of the flat plate through a high-precision nozzle, and the ink is quickly cured using a UV lamp to achieve high-quality printing effects. The positioning mechanism used in flatbed UV printing is a device specially designed for accurately fixing and positioning the flat plate. It ensures that the flat plate remains stable and accurately positioned during the UV printing process to meet high-precision printing requirements.

[0003] When using the existing flatbed UV inkjet printer, a flatbed is placed on an operating table, the flatbed is positioned according to the positioning lines on the operating table, and then the flatbed is UV inkjet printed by the UV inkjet printer. Since the existing positioning mechanism for flatbed UV inkjet printing only uses the positioning lines as position markers, the flatbed is positioned by manually fitting the edge of the flatbed to the positioning lines. Positioning by manually moving the flatbed is inefficient and has low positioning accuracy, which can easily cause deviations in the printing position and affect the printing quality. Utility Model Content

[0004] The utility model aims to provide a positioning mechanism for flatbed UV printing processing, so as to solve the problem of positioning by manually moving the flatbed during flatbed UV printing processing in the current market, as mentioned in the background art.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a positioning mechanism for flat-bed UV inkjet printing processing, comprising an operating table and a support column, the bottom end of the operating table is welded with a support column, the top end of the operating table is provided with four groups of connecting grooves, the bottom ends of the four groups of connecting grooves are welded with guide frames, two groups of servo motors are installed on the inner side of the support column, and the output ends of the two groups of servo motors are connected to threaded rods through couplings.

[0006] Preferably, the outer walls of the two groups of threaded rods are sleeved with two groups of connecting plates, and the inner sides of the four groups of connecting grooves are provided with push blocks extending to the outside of the top end.

[0007] Preferably, the outer wall of the push block is slidably connected to the inner wall of the connecting groove, and the inner wall of the connecting plate is threadedly connected to the outer wall of the threaded rod.

[0008] Preferably, a connecting frame is welded on the inner side of the supporting column, and the connecting frame is connected to the two groups of servo motors by bolts.

[0009] Preferably, the bottom ends of the four groups of push blocks are welded with square rods, the outer walls of the bottom ends of the four groups of square rods are sleeved with square tubes, and the bottom ends of the four groups of square tubes are welded to the top ends of the four groups of connecting plates.

[0010] Preferably, springs are provided inside the four groups of square tubes at the bottom ends of the square rods, sliding grooves are provided on both sides of the four groups of square tubes, and sliding blocks penetrating the sliding grooves are welded to the outer walls of the four groups of square rods.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. When the positioning mechanism positions the flat plate that needs UV printing processing, the flat plate is placed inside the four groups of push blocks, and two groups of servo motors drive two groups of threaded rods to reverse, and the two groups of threaded rods drive four groups of connecting plates to move, and the four groups of connecting plates drive the square tubes, square rods and push blocks to move, and two groups of push blocks clamp the two sides of the flat plate, and the other two groups of push blocks clamp the two ends of the flat plate, so that the positioning mechanism positions the flat plate, and the positioning mechanism can adjust the position of the flat plate at the same time. Through the adjustability of the threaded rod, the positioning mechanism can adapt to flat plates of various sizes, shapes and requirements, thereby improving the versatility and adaptability of the equipment, and facilitating the UV printer to perform UV printing processing on the flat plate.

[0013] 2. When the positioning mechanism needs to perform UV printing on a longer flat plate, the flat plate is placed on the top of the two sets of push blocks.
