[0040] An embodiment of the present application provides a coding device. Figure 1 The present invention is a three-dimensional schematic diagram of an embodiment of the coding device of the present invention from one angle. The coding device includes a coding housing 100, a cover 200, a displacement drive assembly 300, a coding carriage assembly 400, and a controller. The coding housing 100 has an opening 110, and an opening sensor 120 is provided at the edge of the opening 110. The cover 200 includes a trigger 210. The cover 200 has a closed state and an open state. Figure 1 In the closed state, the cover body 200 covers the opening 110 .

[0041] Figure 2 , Figure 3 1 is a three-dimensional schematic diagram of the cover body in an open state in an embodiment of the inkjet device of the present application. In the open state, the cover body 200 exposes the opening 110, and the trigger member 210 causes the cover opening sensor 120 to generate a cover opening sensing signal.

[0042] The cover opening sensor 120 may be a contact switch, and the trigger 210 may be, for example, a trigger arm that can contact the contact switch in the cover-closed state and leave the contact switch in the cover-opened state. In some other embodiments, the cover opening sensor 120 may be other sensors, such as a photoelectric sensor, a magnetic sensor, or an electromagnetic sensor, and the type of the trigger 210 matches the type of the cover opening sensor 120, so that the trigger 210 can trigger the cover opening sensor 120.

[0043] The displacement driving assembly 300 is disposed in the coding housing 100. The coding carriage assembly 400 is installed in the coding housing 100 through the displacement driving assembly 300, and the displacement driving assembly 300 can drive the coding carriage assembly 400 to move along the first direction X.

[0044] The controller 500 is electrically connected to the cover opening sensor 120 , the displacement driving assembly 300 and the inkjet carriage assembly 400 . Figure 4 The schematic diagram of the electrical connection structure of the components in one embodiment of the inkjet device of the present application is shown in FIG. The controller 500 is configured to: after receiving the printing task information, control the displacement drive component 300 to drive the inkjet carriage component 400 to move and control the inkjet carriage component 400 to spray the code to perform the printing operation; after receiving the cover opening sensing signal, control the inkjet carriage component 400 to stop spraying the code and control the displacement drive component 300 to drive the inkjet carriage component 400 to move to the first preset position to stop the printing operation.

[0045] According to the inkjet device of the embodiment of the present application, the edge of the opening 110 of the inkjet housing 100 is provided with a cover opening sensor 120, and the cover body 200 includes a trigger member 210. The cover body 200 has a closed state and an open cover state. In the open cover state, the cover body 200 exposes the opening 110, and the trigger member 210 causes the cover opening sensor 120 to generate an open cover sensing signal. The controller 500 is configured to control the displacement drive component 300 to drive the inkjet carriage component 400 to move and control the inkjet carriage component 400 to spray code after receiving the printing task information, so as to perform the printing operation. The controller 500 is also configured to control the inkjet carriage component 400 to stop spraying code and control the displacement drive component 300 to drive the inkjet carriage component 400 to move to the first preset position after receiving the cover opening sensing signal, so as to stop the printing operation. Therefore, after the printing job has started, if the cover body 200 is opened, the cover opening sensor 120 generates a cover opening sensing signal, and the controller 500 controls the displacement drive assembly 300 and the inkjet carriage assembly 400 to stop the printing job. The inkjet carriage assembly 400 no longer continues to perform the printing job and moves back and forth, providing cover opening protection when the cover is opened, thereby eliminating safety hazards after the cover body 200 is opened.

[0046] In some embodiments, the controller 500 is configured to: after receiving the cover opening sensing signal, control the coding carriage assembly 400 to stop coding, and control the displacement drive assembly 300 to drive the coding carriage assembly 400 to move first to the original printing position and then to the cover opening position, wherein the cover opening position of the coding carriage assembly 400 corresponds to the opening 110, so that the opening 110 exposes the coding carriage assembly 400.

[0047] like Figure 2 After receiving the cover opening sensing signal, the displacement driving component 300 drives the inkjet carriage component 400 to move to the original printing position. Figure 3, the coding carriage assembly 400 first moves to the original printing position and then continues to move to the cover opening position. When the coding carriage assembly 400 is at the cover opening position, the opening 110 exposes the coding carriage assembly 400, so that it is convenient to operate the coding carriage assembly 400 through the opening 110, such as maintaining the coding carriage assembly 400. In this embodiment, by combining the recognition of the cover opening by the cover opening sensor 120 and the control of the coding carriage assembly 400 and the displacement drive assembly 300 by the controller 500, the coding carriage assembly 400 can move to the opening 110 after the coding device is opened, so that it is more convenient to maintain the coding carriage assembly 400. After receiving the cover opening sensing signal, the displacement drive assembly 300 drives the coding carriage assembly 400 to move to the original printing position first, and then drives the coding carriage assembly 400 to move to the cover opening position based on the original printing position, thereby ensuring the position accuracy of the coding carriage assembly 400 reaching the cover opening position.

[0048] In some embodiments, the inkjet printer further includes an original position sensor, which is disposed on the inkjet printer housing 100 and is electrically connected to the controller 500. When the inkjet printer carriage assembly 400 moves to the original printing position, the original position sensor is triggered, so that the original position sensor generates an original position arrival signal. The original position sensor can be a contact switch, a photoelectric sensor, a magnetic sensor, or an electromagnetic sensor.

[0049] In some embodiments, the controller 500 is configured to: after receiving the cover opening sensing signal, control the displacement drive component 300 to drive the coding vehicle component 400 to move toward the original printing position until the original position arrival signal is received, and after receiving the original position arrival signal, control the displacement drive component 300 to drive the coding vehicle component 400 to move in a preset direction and a preset distance, so that the coding vehicle component 400 reaches the cover opening position.

[0050] Figure 5 The figure is a three-dimensional schematic diagram of the displacement drive assembly and the inkjet carriage assembly in one embodiment of the inkjet device of the present application. In some embodiments, the displacement drive assembly 300 includes a first stepper motor 330, and the first stepper motor 330 is used to drive the inkjet carriage assembly 400 to move. The controller 500 controls the preset distance of the inkjet carriage assembly 400 by controlling the number of running steps of the first stepper motor 330. Therefore, after opening the cover, the controller can control the displacement drive assembly 300 to accurately drive the inkjet carriage assembly 400 to the cover opening position.

[0051] like Figure 4In some embodiments, the controller 500 includes a first processor 510 and a second processor 520. The first processor 510 is electrically connected to the cover opening sensor 120, and the second processor 520 is electrically connected to the first processor 510, the displacement drive assembly 300, and the coding carriage assembly 400. The first processor 510 can receive print task information and cover opening sensing signals and send them to the second processor 520. The second processor 520 is used to control the movement of the displacement drive assembly 300 and control the coding carriage assembly 400 to spray.

[0052] like Figure 1 In some embodiments, the inkjet printer further includes a display panel 600, which is disposed outside the inkjet printer housing 100, and the display panel 600 is electrically connected to the controller 500. The controller 500 is configured to control the display panel 600 to display the cover opening information after receiving the cover opening sensing signal. In this embodiment, the display panel 600 is electrically connected to the first processor 510. When the cover body 200 is opened, the trigger member 210 causes the cover opening sensing member 120 to generate a cover opening sensing signal, and the first processor 510 controls the display panel 600 to display the cover opening information after receiving the cover opening sensing signal, and sends the cover opening sensing signal to the second processor 520. The second processor 520 controls the inkjet printer carriage assembly 400 to stop inkjet printing and controls the displacement drive assembly 300 to drive the inkjet printer carriage assembly 400 to move to the first preset position to stop the printing operation.

[0053] The controller 500 includes at least one processor. In this embodiment, the controller 500 includes a first processor 510 and a second processor 520. In some embodiments, the controller further includes a memory. The memory is electrically connected to the at least one processor, and instructions are stored in the memory. The at least one processor calls the instructions in the memory so that the controller 500 executes control of the inkjet printer.

[0054] The above-mentioned processor may include a central processing unit (CPU), or an application specific integrated circuit (ASIC), or may be configured to implement one or more integrated circuits of the embodiments of the present application.

In appropriate cases, the memory may include a removable or non-removable (or fixed) medium. In appropriate cases, the memory may be inside or outside the integrated gateway disaster recovery device. In a specific embodiment, the memory is a non-volatile solid-state memory. In a specific embodiment, the memory includes a read-only memory (ROM). In appropriate cases, the ROM may be a mask-programmed ROM, a programmable ROM (PROM), an erasable PROM (EPROM), an electrically erasable PROM (EEPROM), an electrically rewritable ROM (EAROM), or a flash memory, or a combination of two or more of these.

[0056] In one example, the controller 500 may also include a communication interface and a bus. The processor, memory, and communication interface are connected through the bus and communicate with each other. The communication interface is mainly used to implement communication between modules, devices, units, and / or equipment in the embodiments of the present application.

[0057] The bus includes hardware, software or both, and the parts of the online data flow billing equipment are coupled to each other. For example, but not limitation, the bus may include accelerated graphics port (AGP) or other graphics bus, enhanced industrial standard architecture (EISA) bus, front-end bus (FSB), hypertransport (HT) interconnection, industrial standard architecture (ISA) bus, infinite bandwidth interconnection, low pin count (LPC) bus, memory bus, micro channel architecture (MCA) bus, peripheral component interconnection (PCI) bus, PCI-Express (PCI-X) bus, serial advanced technology attachment (SATA) bus, video electronics standard association local (VLB) bus or other suitable bus or two or more of these combinations. In suitable cases, the bus may include one or more buses. Although the present application embodiment describes and shows a specific bus, the application considers any suitable bus or interconnection.

[0058] like Figure 5 The displacement driving assembly 300 includes a first guide rail 310 , a guide rail base 320 , a first stepper motor 330 , and a transmission member 340 .

[0059] The first guide rail 310 extends along the first direction X, and the inkjet character carriage assembly 400 is installed on the first guide rail 310. The guide rail base 320 is arranged in the inkjet character housing 100, and the first guide rail 310 is installed on the guide rail base 320. The first stepper motor 330 is installed on the guide rail base 320. The transmission member 340 transmits and connects the first stepper motor 330 with the inkjet character carriage assembly 400, so that the first stepper motor 330 can drive the inkjet character carriage assembly 400 to move along the first guide rail 310. In this embodiment, the transmission member 340 includes a gear set and a belt transmission assembly. In some other embodiments, the transmission member 340 can be other structures connected between the first stepper motor 330 and the inkjet character carriage assembly 400.

[0060] Figure 6 This is a three-dimensional schematic diagram of another angle of an embodiment of the coding device of the present application. Figure 6 One side outer surface of the coding housing 100 includes a printing surface 130 , and the printing surface 130 is provided with a coding opening 131 .

[0061] Figure 7 1 is a three-dimensional schematic diagram of a coding carriage assembly in an embodiment of a coding device of the present application. In some embodiments, the coding carriage assembly 400 includes a carriage 410 and a front-rear drive assembly 420. The carriage 410 includes an inkjet head 411 capable of spraying ink. The front-rear drive assembly 420 is used to drive the carriage 410 to move in a direction perpendicular to the printing surface 130, so that the inkjet head 411 can protrude from the coding opening 131 or be recessed in the coding opening 131.

[0062] In the above embodiment, the front and rear drive components 420 are used to drive the carriage 410 to move in a direction perpendicular to the printing surface 130, so that the inkjet head 411 can protrude from the coding opening 131 or be recessed in the coding opening 131. When the surface to be coded of the object to be coded is concave, the front and rear drive components 420 drive the carriage 410 to move so that the inkjet head 411 protrudes from the coding opening 131, ensuring that there is a suitable coding distance between the inkjet head 411 and the concave surface to be coded. When the surface to be coded of the object to be coded is convex, the front and rear drive components 420 drive the carriage 410 to move so that the inkjet head 411 is recessed in the coding opening 131, ensuring that there is a suitable coding distance between the inkjet head 411 and the convex surface to be coded. Therefore, the coding device can adaptively adjust the coding distance according to whether the surface to be coded is concave or convex, or when there are other printing requirements, so as to ensure stable coding quality and improve the coding effect.

[0063] In some embodiments, the controller is configured to: after receiving the print task information, control the front and rear drive components 420 to drive the carriage 410 to move until the inkjet head 411 is 2 mm to 5 mm away from the surface of the object to be coded.

[0064] In the above embodiment, the front and rear drive components 420 can drive the carriage 410 to move in a direction perpendicular to the printing surface 130. After receiving the printing task information, the controller controls the front and rear drive components 420 to drive the carriage 410 to move until the inkjet head 411 is 2 mm to 5 mm away from the surface to be coded of the object to be coded, so that there is an optimal coding distance between the inkjet head 411 and the surface to be coded, thereby ensuring stable coding quality.

[0065] In some embodiments, the front-rear drive assembly 420 includes a carriage base 421, a driving member 422, and a reciprocating transmission member 423. The carriage 410 is movably disposed on the carriage base 421 in a direction perpendicular to the printing surface 130. The driving member 422 is mounted on the carriage base 421. The reciprocating transmission member 423 connects the driving member 422 with the carriage 410, so that the driving member 422 can drive the carriage 410 to move.

[0066] In some embodiments, the carriage 410 further includes a support frame 412 and an ink cartridge 413 . The support frame 412 is connected to the front and rear drive assembly 420 . The inkjet head 411 is installed on the support frame 412 . The ink cartridge 413 is detachably installed on the support frame 412 .

[0067] like Figure 6 In this embodiment, the reciprocating transmission member 423 is a screw assembly, which includes a screw 4231 and a movable block 4232 that cooperates with the screw 4231. The screw 4231 is installed on the carriage base 421 and extends in a direction perpendicular to the printing surface 130. The screw 4231 is connected to the driving member 422, and the movable block 4232 is connected to the carriage 410. The driving member 422 drives the screw 4231 to rotate so that the movable block 4232 moves along the extension direction of the screw 4231.

[0068] like Figure 6 In this embodiment, the driving member 422 is a second stepping motor 422a. The second stepping motor 422a rotates when powered on, thereby driving the lead screw 4231 to rotate.

[0069] Figure 8 This is a three-dimensional schematic diagram of a coding carriage assembly in an alternative embodiment of the coding device of the present application. In the alternative embodiment, the driving member 422 is a rotating handle 422b, and the rotating handle 422b can be rotated by hand, thereby driving the screw rod 4231 to rotate.

[0070] In this embodiment, after the cover 200 is opened, the coding carriage assembly 400 can move to the cover opening position, at which time the coding carriage assembly 400 is located at the opening 110, so that it is more convenient to replace the ink cartridge 413 of the coding carriage assembly 400.

[0071] The embodiment of the present application also provides a control method for a coding device, which is used to control the coding device of any of the aforementioned embodiments. The coding device includes a coding housing 100, a cover body 200, a displacement drive assembly 300, and a coding carriage assembly 400. The coding housing 100 has an opening 110, and an opening sensor 120 is provided at the edge of the opening 110. The cover body 200 includes a trigger member 210. The cover body 200 has a closed state and an open state. In the closed state, the cover body 200 covers the opening 110. In the open state, the cover body 200 exposes the opening 110, and the trigger member 210 causes the opening sensor 120 to generate an opening sensing signal. The displacement drive assembly 300 is disposed in the coding housing 100. The coding carriage assembly 400 is installed in the coding housing 100 through the displacement drive assembly 300, and the displacement drive assembly 300 can drive the coding carriage assembly 400 to move along the first direction X. The controller 500 is electrically connected to the cover opening sensor 120 , the displacement driving assembly 300 and the inkjet carriage assembly 400 .

[0072] In this embodiment, the control method of the coding device includes step S110 and step S120.

[0073] In step S110, after receiving the printing task information, the displacement driving component 300 is controlled to drive the coding carriage component 400 to move and control the coding carriage component 400 to perform coding to perform the printing operation.

[0074] In step S120, after receiving the cover opening sensing signal, the coding carriage assembly 400 is controlled to stop coding and the displacement driving assembly 300 is controlled to drive the coding carriage assembly 400 to move to the first preset position to stop the printing operation.

[0075] According to the control method of the inkjet device of the embodiment of the present application, a cover-opening sensor 120 is provided at the edge of the opening 110 of the inkjet housing 100, and the cover body 200 includes a trigger member 210. The cover body 200 has a closed state and an open state. In the open state, the cover body 200 exposes the opening 110, and the trigger member 210 causes the cover-opening sensor 120 to generate an open sensing signal. After receiving the printing task information, the displacement drive component 300 is controlled to drive the inkjet carriage component 400 to move and control the inkjet carriage component 400 to spray code to perform a printing operation. After receiving the cover-opening sensing signal, the inkjet carriage component 400 is controlled to stop spraying code and the displacement drive component 300 is controlled to drive the inkjet carriage component 400 to move to a first preset position to stop the printing operation. Therefore, after the printing job has started, if the cover body 200 is opened, the cover opening sensor 120 generates a cover opening sensing signal, the displacement drive assembly 300 and the coding carriage assembly 400 will stop the printing job, and the coding carriage assembly 400 will no longer continue to perform the printing job and move back and forth, providing cover opening protection when the cover is opened, thereby eliminating safety hazards after the cover body 200 is opened.

[0076] In some embodiments, after receiving the cover-opening sensing signal, the step S120 of controlling the inkjet carriage assembly 400 to stop inkjet printing and controlling the displacement driving assembly 300 to drive the inkjet carriage assembly 400 to move to the first preset position to stop the printing operation includes: after receiving the cover-opening sensing signal, controlling the inkjet carriage assembly 400 to stop inkjet printing, and controlling the displacement driving assembly 300 to drive the inkjet carriage assembly 400 to move to the original printing position first and then to the cover-opening position, wherein the cover-opening position of the inkjet carriage assembly 400 corresponds to the opening 110, so that the opening 110 exposes the inkjet carriage assembly 400. Therefore, after receiving the cover-opening sensing signal, the displacement driving assembly 300 drives the inkjet carriage assembly 400 to move to the original printing position first, and then drives the inkjet carriage assembly 400 to move to the cover-opening position based on the original printing position, thereby ensuring the position accuracy of the inkjet carriage assembly 400 reaching the cover-opening position. In this embodiment, by combining the recognition of the cover opening by the cover opening sensor 120 and the control of the coding carriage assembly 400 and the displacement drive assembly 300 by the controller 500, the coding carriage assembly 400 can move to the opening 110 after the cover of the coding device is opened, thereby making it more convenient to maintain the coding carriage assembly 400.

In the open state, the cover body 200 exposes the opening 110, and the trigger member 210 causes the opening sensor 120 to generate an opening sensing signal.
