[0044] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0045] To address the issues of high costs and inconsistent quality associated with manual label pasting on outdoor units, this invention provides a UV inkjet printing system. By developing a control system and integrating it with Onepass UV inkjet printing technology, the system enables automated production of printed products that meet diverse production needs, ultimately achieving flexible UV inkjet printing.

[0046] like Figures 1-7 As shown, specifically, the UV inkjet printing system includes a first transmission and transport module, a UV inkjet printing module 2, a second transmission and transport module, a transfer module 3, and a sensing and identification module; wherein:

[0047] The second transmission and transport module is located next to the first transmission and transport module for transporting materials to be assembled. Specifically, the second transmission and transport module and the first transmission and transport module are arranged in parallel with a spacing between them, with the spacing being sufficient to meet the working radius of the transfer module 3.

[0048] The sensing and identification module is located on the second transmission and transport module, used to transmit the printing information of the materials to be assembled to the UV printing module 2. It should be noted that the second transmission and transport module transports two types of materials: one type includes the process board and the external machine, and the other type consists only of the process board, used to regulate the production rhythm. Only when the process board and external machine are transported does the material need to be printed on the panel 300 before the panel 300 is placed on the external machine; when the material consists only of the process board is transported on the second transmission and transport module, no printing on the panel 300 is required, and it is released directly. This part of the control is an action executed by the control module and will not be elaborated further here. When the control module determines whether panel 300 printing is required (i.e., whether the transmitted material is a process board plus an external unit), information binding must be performed manually before the material enters the conveyor line. The system then generates printing information for that material. If the transmitted material is only a process board, information binding is unnecessary, and printing-free information is generated in the system. When the sensing module identifies the material, the system compares the identified information with the information in the system. If the information matches printing-free information, the printing module controls panel 300 printing; otherwise, no action is taken, and the second transmission and transport module directly transports the process board to the next station.

[0049] The UV printing module 2 is mounted on the first transmission and transport module to perform surface printing on the transported materials. It should be noted that the UV printing module 2 in this embodiment can be implemented using existing products, and no modifications are necessary; therefore, further details are omitted. Furthermore, to achieve precise printing, the UV printing module 2 needs to be equipped with a visual recognition or visual positioning mechanism 13 and a visual inspection system. These systems identify the areas on the panel 300 to be printed, then control the UV printing module 2 to move to the starting printing position for precise printing. The visual recognition or visual positioning mechanism 13 can be a camera, a video camera, etc., or it can be implemented using existing structures used for positioning or recognition in various fields. The visual inspection unit is used to determine the quality of the printing on the panel 300.

[0050] The transfer module 3 is positioned between the first and second transmission transport modules to place the printed material into the material to be assembled. Specifically, the transfer module 3 includes a robotic arm.

[0051] This invention achieves automated printing using Onepass UV inkjet printing technology, saving on the costs of purchasing printed materials and labor, including the cost of purchasing printed materials, the cost of employees pasting printed materials, and the cost of employees operating the UV inkjet printing equipment; it ensures consistent and stable product quality, and while maintaining production efficiency, the printing effect can guarantee that the product will not fade or discolor for 10 years in the face of external weathering; it achieves "fast in, fast out" production, with the printing cycle controlled within 8-9 seconds, reducing the number of employees by 1, and lowering costs by 30% compared to traditional manual label pasting.

[0052] As a further improvement of this utility model, the sensing and identification module includes a first RFID sensor and a second RFID sensor arranged at intervals.

[0053] It should be noted that the first RFID sensor and the second RFID sensor have the same structure, but are set separately. The distance between them is such that the time required for the process board and the external unit to be transferred from the first RFID sensor to the second RFID sensor on the second transmission and transport module is equal to the time required for a panel 300 to go from preparation to printing completion.

[0054] As a further improvement of this utility model, the first transmission and transportation module includes belt conveyors A11 and B12 arranged in sequence. Belt conveyors A11 and B12 operate independently and are each driven by a set of motors, thus forming a belt conveyor system with two sets of motors independently controlled. The UV printing module 2 is movably arranged beside belt conveyor A11 and can move left, right, up, and down relative to belt conveyor A11. In this embodiment, the UV printing module 2 can be controlled by a cross slide 21 to drive the UV printing module 2 to move horizontally along the X-axis and move vertically along the Y-axis. The transfer module 3 is arranged between belt conveyor B12 and the second transmission and transportation module.

[0055] As a further improvement of this utility model, in order to achieve precise printing and prevent displacement or swaying of the panel 300 during movement, in this embodiment, the first transmission and transport module further includes a positioning mechanism 13, a first photoelectric sensor 14, a second photoelectric sensor, a translation component 15, and a placement platform 16; wherein:

[0056] Positioning mechanisms 13 are installed on both sides of the belt conveyor A11 to position the material left and right.

[0057] The first photoelectric sensor 14 is disposed on the side of the conveyor belt A11 to sense the material being transported to the position; furthermore, the first photoelectric sensor 14 is disposed directly opposite the UV inkjet printing module 2, so that when the material moves to the position of the UV inkjet printing module 2, it can be sensed by the first photoelectric sensor 14 so that the material can accurately stop in place.

[0058] In this embodiment, a support platform 18 is also provided on the side of the belt conveyor A11 to support the control components of the first photoelectric sensor 14 and the stopper 17.

[0059] The placement platform 16 is located beside the end of the conveyor belt B12 and is used to hold the sprayed material and the second photoelectric sensor.

[0060] The second photoelectric sensor is installed on the placement platform 16 and faces the end of the belt conveyor B12 to sense the material that has been transported to the designated location.

[0061] The translation component 15 is disposed between the conveyor belt B12 and the placement table 16 to translate the material from the conveyor belt B12 onto the placement table 16.

[0062] As a further improvement of this utility model, the positioning mechanism 13 includes a first positioning plate 131, a second positioning plate 132, a push plate 133, and a pneumatic propulsion machine 134; wherein:

[0063] The first positioning plate 131 is fixed to one side of the belt conveyor A11;

[0064] The pneumatic propulsion machine 134 is fixed on the other side of the belt line A11, and the pneumatic propulsion machine 134 is connected to the second positioning plate 132 through the push plate 133, which can drive the second positioning plate 132 to move back and forth in a way that approaches or moves away from the first positioning plate 131.

[0065] As a further improvement of this utility model, the positioning mechanism 13 also includes a stopper 17 disposed at the front end of the second positioning plate 132. In this embodiment, the stopper 17 includes a baffle and a telescopic cylinder; the baffle is rotatably disposed beside the belt line A11 via a rotating shaft to form a horizontal seesaw structure, and the telescopic cylinder is placed on the support platform 18, and the telescopic cylinder is connected to the end of the baffle closest to the rotating shaft, which can drive the baffle to rotate 90 degrees in the horizontal direction.

[0066] Of course, the stopper 17 can also adopt other structures. For example, the stopper 17 includes a baffle and a telescopic cylinder; the telescopic cylinder is connected to the baffle and can drive the baffle to move vertically up and down relative to the belt line A11; or, the stopper 17 includes a baffle and a motor, the drive shaft of the motor is connected to the baffle, and can drive the baffle to rotate horizontally when the motor rotates. Of course, other structures can also achieve this function, and this utility model does not specifically limit them.

[0067] This utility model's UV inkjet printing system includes an RFID sensing and receiving system, an RFID reading and writing system, two independent motor control systems, and a fixture system (translation component 15). Utilizing this control system, it achieves perfect control over all equipment in the entire UV inkjet printing process, keeping the printing cycle time within 8-9 seconds, thus realizing a "fast in, fast out" production mode. This system, combined with Onepass inkjet printing technology, solves the problems of traditional UV printing's manual operation, long working hours, and low efficiency, perfectly integrating UV printing technology with assembly line production. This achieves the goals of reducing manpower, increasing efficiency, and lowering costs, while simultaneously realizing a revolutionary breakthrough in UV direct printing technology, meeting the demands of a rapidly developing market for new quality productivity changes, and enhancing product competitiveness.

[0068] As a further improvement of this utility model, the translation component 15 includes a gantry frame 151, a guide rail 152, a fixing frame 153, and a suction cup 154; wherein:

[0069] Gantry 151 is installed between conveyor belt B12 and placement platform 16;

[0070] Guide rail 152 is installed on top of gantry frame 151;

[0071] The fixing bracket 153 is slidably mounted on the guide rail 152;

[0072] Suction cups 154 are located at the four corners of the bottom of the mounting bracket 153 and are used to adsorb the four corners of the panel 300.

[0073] To facilitate transmission and reduce power consumption, in this embodiment, the belt conveyor A11 includes an inclined conveyor body 111 and a flat conveyor body 112 arranged sequentially. The panel 300 can slide down the inclined conveyor body 111 by gravity, or a motor can be installed inside the inclined conveyor body 111 for transmission.

[0074] As a further improvement of this utility model, the first positioning plate 131 and the second positioning plate 132 are provided with outwardly bent guide portions 135 at the end positions of the inclined plane line 111 to ensure that the panel 300 will not fall to the ground when it falls from the inclined plane line 111 to the flat plane line 112, thus ensuring the smooth transfer and good positioning of the panel 300.

[0075] This utility model's UV inkjet printing system breaks through the original cumbersome and inefficient printing process to automated printing (without the need for manual parameter adjustment or command issuance). By using this inkjet printing system, UV inkjet printing technology is perfectly integrated with the production line, achieving the goal of reducing personnel and production costs, while realizing a "fast in, fast out" production mode and ensuring the production line's cycle time.

[0076] Example 1:

[0077] In this embodiment, a flexible UV inkjet printing system is provided, including a first transmission and transport module consisting of belt conveyor B12 and belt conveyor A11 from left to right. Belt conveyor A11 is further composed of a planar line body 112 and an inclined plane. The material to be printed is transported from the right inclined plane body 111 to the planar line body 112. After printing is completed on the planar line body 112, it is transported to the leftmost belt conveyor B12. When the printed material is transported to belt conveyor B12, it is picked up by a suction cup 154 ​​and placed on a placement table 16 along a guide rail 152, waiting for a robotic arm to pick it up and send it to the second transmission and transport module.

[0078] The UV inkjet printing module 2 consists of a printing bracket and an inkjet printing device. The printing bracket is responsible for supporting the inkjet printing device and the cross slide 21 that moves the inkjet printing device up and down and left and right.

[0079] A positioning mechanism 13 is installed on the conveyor belt A11. The positioning mechanism 13 consists of a first photoelectric sensor 14, a stopper 17, a first positioning plate 131, a second positioning plate 132, a pusher plate 133, and a pneumatic propulsion machine 134. The first photoelectric sensor 14 and the stopper 17 are placed on a support platform 18 next to the conveyor belt A11. One side of the first positioning plate 131 in the left and right positioning part is fixed to one side of the conveyor belt A11, and the second positioning plate 132 on the other side is matched with the pusher plate 133 and the pneumatic propulsion machine 134. When the material to be printed arrives at the first photoelectric sensor 14, the first photoelectric sensor 14 receives a signal, and the system controls the stopper 17 to extend and block the material to be printed. The pneumatic propulsion machine 134 pushes the pusher plate 133 to complete the left and right positioning of the material to be printed, preparing for the positioning of the printing equipment.

[0080] like Figure 8 As shown, the working method of the UV inkjet printing system of this utility model is as follows:

[0081] Order information collection:

[0082] The UV inkjet printing system is equipped with a dedicated RFID sensing and receiving system. After completing the previous printing job, the equipment will automatically identify the information based on the order information transmitted by RFID and retrieve the corresponding template from the pre-edited pattern library according to the pattern required by the order information.

[0083] The specific implementation is as follows: An RFID sensor chip is stored on the process board, and a corresponding barcode is present on the external machine body. Before being transported to the second transmission module, the RFID sensor chip on the process board and the barcode on the machine body are manually scanned and the information is bound, thereby generating the information to be printed in the system control unit. Two RFID sensors are installed on the second transmission module: the first RFID sensor, after sensing the RFID signal (process board chip) on the process board, transmits the signal to the printing equipment, and the system controls the printing equipment to retrieve the corresponding template for printing; the second RFID sensor, after sensing the RFID signal on the process board, transmits the signal to the robotic arm, preparing to grasp the printed panel 300. If the process board is empty, there is no need to bind the external machine information with the process board information. The signal received by the sensor only contains the information of the process board, and the signal transmitted to the equipment (printing equipment, robotic arm, suction cup 154) does not contain any information related to the external machine. After system identification, the empty board will be released directly.

[0084] Printing preparation:

[0085] The printhead used in UV printing module 2 is an innovative improvement on traditional UV printheads, consisting of multiple integrated printheads and a dedicated printhead control system. Of course, the printheads in UV printing module 2 can also be implemented using existing technology. After receiving order information, the printing equipment automatically adjusts the position and orientation of each printhead on the integrated printhead according to the pattern template. After the panel 300 is positioned horizontally, the equipment automatically performs vertical positioning based on the height of the panel 300, adjusting the printhead height to ensure the distance between the printhead and the panel 300 is within the set range.

[0086] Printing is in progress:

[0087] After adjusting the position and height of the printhead, open the ink pipeline valve to spray out the ink of the corresponding color, completing the printing of the pattern in one go.

[0088] Equipment return to its proper place:

[0089] After completing the printing job, the equipment automatically returns to its original set height, receives and reads the next order information, and prepares for the next printing.

[0090] Positioning and transmission modules:

[0091] 300 positioning operation for unprinted panel:

[0092] Belt conveyors A11 and B12 are controlled by two independent motor control systems. Belt conveyor A11 is equipped with photoelectric control stoppers 17, left and right end clamping and positioning mechanisms 13, and top positioning (used in conjunction with a visual recognition component in the printing module, such as a camera or webcam, to locate the position). After the panel 300 is transported from the belt conveyor ramp onto belt conveyor A11, it is transported forward along the left and right end clamping (positioning mechanisms 13). After triggering the first photoelectric sensor 14, the control system receives the signal transmitted by the first photoelectric sensor 14, controls the stopper 17 to extend and block the panel 300, and simultaneously controls the motor system of belt conveyor A11 to stop running, ensuring that the panel 300 stops stably. The control system controls the left and right positioning mechanisms 13 to work, clamping the panel 300 and preparing it for printing.

[0093] Complete the transportation of 300 inkjet-printed panels:

[0094] After printing is completed, the printing system transmits a signal indicating that printing is complete. The visual inspection system checks the printing effect. If it is qualified, the control system controls the stopper 17 and the positioning mechanism 13 to retract, and controls the motor system of the conveyor belt A11 to operate, transporting the panel 300 to the conveyor belt B12. After the panel 300 is transported to the photoelectric sensing area on the conveyor belt B12 (that is, the area that the second photoelectric sensor can recognize), a photoelectric signal is triggered. The system receives this signal and controls the motor system of the conveyor belt B12 to stop running. Then, the translation component 15 moves and uses the suction cup 154 ​​to pick up the panel 300, and then moves it to the placement table 16, releasing the panel 300, waiting for the robot arm to pick up the printed panel 300 to the second transmission and transport module. If the visual inspection of the printing effect is unqualified, an alarm is issued.

[0095] Work efficiency: From the start of printing to the completion of printing, it should be controlled within 8-9 seconds.
