Semi-automated sublimation printing apparatus
View Patent ↗A dye sublimation apparatus is disclosed. The apparatus is configured to either print one or more images onto transfer media, or to print images directly onto products. A selected product to receive the image(s) is positioned on a platen configured to receive one or more types of such products into channels matching those products' dimensions. Proper positioning of the transfer media (or the product, when directly printed) is facilitated by aligning fiducial markers printed on the transfer media and/or product with one or more lights disposed on the platen. The apparatus comprises one or more heating platens configured to sublimate one or more sides of the product in a single thermal cycle with a predetermined temperature, pressure, and duration based on properties of the product. The product platen is translated inside and out of the apparatus by a reversible motor.
1. An apparatus for sublimating an image on a product, comprising:
a dye sublimation transfer printer configured to print a digital image file representing an image on a sheet of transfer media;
a platen configured to receive and secure the product for sublimation,
wherein the platen is configured to receive one or more different types of products into dedicated channels designed to fit the dimensions of each type of product;
at least one light disposed on the platen to assist with alignment of one or more markers printed onto the transfer media;
one or more heating platens configured to engage the transfer media and sublimate the printed image onto one or more sides of the product;
a housing substantially enclosing the dye sublimation transfer printer, platen, light, and one or more heating platens in a manner that prevents a user from contacting the enclosed components; and
a user interface device configured to confirm selection of the image to be printed.
2. The apparatus of claim 1 , wherein the platen further comprises one or more clamps configured to secure at least a portion of the transfer media into contact with the platen.
3. The apparatus of claim 1 , wherein the platen further comprises one or more clamps configured to secure at least a portion of the product into contact with the platen.
4. The apparatus of claim 1 , further comprising:
a reversible motor configured to translate the platen to various positions within the apparatus; and
a controller configured to control the motion of the motor.
5. The apparatus of claim 4 , wherein the reversible motor is configured by the controller to translate the platen from a position within the housing to a position outside of the housing for loading or removal of the product.
6. The apparatus of claim 1 , wherein the apparatus further comprises:
a lever arm assembly configured to transfer pressing force to the one or more heating platens;
a reversible motor configured to generate the pressing force and operate the lever arm assembly; and
a controller configured to control the motion of the motor.
7. The apparatus of claim 6 , wherein the lever arm assembly and the one or more heating platens are coupled together by at least one or more springs with a known spring constant.
8. The apparatus of claim 1 , wherein the one or more heating platens sublimate the printed image onto one or more sides of the selected product in a single thermal cycle, the thermal cycle including a predetermined temperature, pressure, and duration.
9. The apparatus of claim 8 , further comprising a controller including one or more processors,
wherein the controller is configured to automatically determine one or more of the temperature, pressure, or duration of the thermal cycle based upon one or more properties of the product to be sublimated.
10. The apparatus of claim 9 , wherein the properties of the product to be sublimated are accessed automatically from a memory or database associated with the user interface device.
11. The apparatus of claim 9 , wherein the properties of the product to be sublimated are determined by the apparatus by reading an indicia printed on the product containing the properties.
