Detailed Description
The embodiment of the jig for printing curved glass according to the present invention will be further described with reference to fig. 2 to 4.
The utility model provides a tool for curved surface glass printing, includes bottom plate 31, be provided with fixed positioning plate 32 and slip positioning plate 33 on the bottom plate 31, form fixed curved surface glass 2's locating area 34 between fixed positioning plate 32 and the slip positioning plate 33, sliding connection just is provided with locking mechanical system between the two between slip positioning plate 33 and the bottom plate 31.
During printing, the whole jig moves along with the conveying track and carries the curved glass 2 to the lower part of the flexible pad printing roller 1 for printing.
The distance between the sliding positioning plate 33 and the fixed positioning plate 32 is adjusted according to the size of the curved glass 2 to be slightly larger than the curved glass 2, the curved glass 2 is placed in the positioning area 34, the sliding positioning plate 33 is slowly moved to the curved side surface of the curved glass 2 to abut against the fixed positioning plate 32 and the sliding positioning plate 33, then the sliding positioning plate 33 is locked by a locking mechanism, the curved glass 2 is limited in the positioning area 34 at the moment, wherein the height of the upper surfaces of the fixed positioning plate 32 and the sliding positioning plate 33 is preferably basically the same as the height of the curved side surface of the curved glass 2 or slightly lower than the height of the curved side surface of the curved glass 2, and when the curved side surface of the curved glass 2 passes through the lower part of the flexible pad printing roller 1, even if the extrusion force of the flexible pad printing roller 1 is larger, the curved side surface of the curved glass 2 is supported by the fixed, the above fixing method is also applicable to glass with only one side being a curved surface.
The locking mechanism comprises an adjusting screw rod 311, the adjusting screw rod 311 is rotatably connected with the bottom plate 31, the adjusting screw rod 311 is in threaded connection with the sliding positioning plate 33, fine threads are adopted between the adjusting screw rod 311 and the sliding positioning plate 33, and the sliding positioning plate 33 can be finely adjusted.
In the embodiment, the locking mechanism is mainly used for fixing the position of the sliding positioning plate 33, so that the side surface of the curved glass 2 abuts against the fixed positioning plate 32 and the sliding positioning plate 33, and a large extrusion force is not required during the abutting, so that the locking mechanism can also adopt the matching of a locking pin and a locking hole, and a plurality of locking holes are pre-arranged on the sliding positioning plate 33 and the bottom plate according to the size of the common curved glass 2; or the locking mechanism can also directly adopt a spring and can be automatically adjusted according to the size of the curved glass 2.
