[0009] To more clearly illustrate the technical solutions of the embodiments of this application, the accompanying drawings used in the embodiments will be briefly introduced below. It should be understood that the following drawings only show some embodiments of this application and should not be regarded as a limitation of the scope. For those skilled in the art, other related drawings can be obtained based on these drawings without creative effort.

[0011] Figure 2 This is the circuit diagram of this utility model. Detailed Implementation
[0012] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.
[0013] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.
[0014] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0015] In the description of this application, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this application is in use. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0016] Furthermore, terms such as "horizontal," "vertical," and "sag" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.
[0017] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "set up," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0018] like Figure 1-2As shown, a printhead cascading circuit based on a SATA cable includes a SATA port, multiple SATA-IN ports, and multiple SATA-OUT ports. The SATA port is located inside the motherboard, while the SATA-IN and SATA-OUT ports are respectively located inside the printhead board. The SATA port of the motherboard is connected to the SATA-IN port of the adjacent printhead board, and the SATA-OUT port of the printhead board is connected to the SATA-IN port of the adjacent printhead board. Encoded switches are provided between the SATA port and the SATA-IN port, and between the SATA-OUT port and the SATA-IN port for control. This invention integrates SATA-IN and SATA-OUT ports into the printhead board, allowing adjacent printhead boards to communicate and simultaneously control multiple printheads for printing. The circuit is simple, with low manufacturing and maintenance costs, and the SATA cable has good shielding, fundamentally improving EMC resistance.
[0019] In this embodiment, the encoding switch control is a hexadecimal encoding switch control; the SATA lines are controlled by rotating the hexadecimal dial (0-F) of the encoding switch. The dial directly corresponds to the SATA device, and a single rotation can complete the instant switching of channels 1-16. Each SATA line and its circuit are independently controlled, and the anti-interference capability is strong.
[0020] In this embodiment, the headboard has a built-in SATA Device controller, which is electrically connected to the SATA-IN port and the SATA-OUT port respectively; each headboard has a built-in SATADevice controller to receive and parse data.
[0021] This invention employs data synchronization and triggering, transmitting hardware trigger signals through Pin 11 in the SATA power cable to ensure synchronized operation of multiple nozzles (error <0.1μs); and utilizes SATA's Spread Spectrum Clocking (SSC) and timestamp marking to ensure consistent data timing.
[0022] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
