[0057] Wherein: the ink spray terminal is fixedly mounted on the second sliding block.

[0058] In this embodiment, the first sliding block and the second sliding block are driven to move based on a single-axis driver driving a lead screw mechanism.

[0059] The structure of the flat automatic printing device in this embodiment is as follows Figure 2 As shown in FIG. 1 , the device mainly consists of three parts: a device frame 1, a conveying mechanism 2, and a printing mechanism 3. Figure 3 As shown, the equipment frame 1 is composed of the following parts: the electronic control components and the pneumatic component mounting plate are placed in the chassis, the remaining space is used for wiring, and the indicator light and acrylic plate are installed on the outer cover. Figure 4 As shown, the mechanism is mainly composed of a synchronous belt conveyor, a mounting base 31, a single-axis drive, a clamping plate 24, etc., and is used to convey the products to be processed (parts, such as Figure 1 As shown in the figure, it moves horizontally along the X-axis direction. The servo motor drives the synchronous belt to achieve the conveying of parts of various models and volumes in the production requirements; the servo motor drives the single-axis driver and the clamping plate 24 to guide the parts running on the synchronous belt to prevent the parts from deflecting during operation and affecting the printing. The actual operation of the mechanism is stable, ensuring the consistency of the appearance after the ink is printed. The printing mechanism 3 and its components are as follows Figure 5As shown, the mechanism is mainly composed of a single-axis driver, a servo motor, an inkjet printer nozzle 4, etc., X and Y two printing mechanisms 3, the nozzle 4 mounting block is fixed on two high-strength single-axis drivers, the single-axis driver is equipped with a servo motor drive, and the tool is moved in the X-axis and Y-axis through the single-axis driver, and the nozzle 4 is advanced and withdrawn. The repeated positioning accuracy is ±0.01mm, and the qualified rate has reached 100% after production verification.

[0060] See also Figure 4 The conveying mechanism 2 of this embodiment is used to convey the products to be processed horizontally along the X-axis direction, which is achieved by driving the synchronous belt with a servo motor. The mechanism meets the production requirements for conveying parts of various models and volumes, and runs stably, ensuring the appearance consistency requirements after ink printing.

[0061] See also Figure 5 The printing mechanism 3 of this embodiment is mainly composed of a single-axis driver, a servo motor, an inkjet printer nozzle 4, etc. The X and Y printing mechanisms 3 and the nozzle 4 mounting blocks are fixed on two high-strength single-axis drivers. The single-axis driver is equipped with a servo motor drive. The tool is moved in the X-axis and Y-axis through the single-axis driver, and the nozzle 4 is advanced and withdrawn. The repeated positioning accuracy is ±0.01mm, and the qualified rate has reached 100% after production verification.

[0062] Electronic control system: The technical difficulty in the electrical aspect is how to ensure the repeated positioning accuracy of the logo.

[0063] Development of programs for fine-tuning the printing position and production statistics accurate to year / month / day / hour.

[0064] In order to solve the problem of repeated positioning accuracy of equipment printing, this embodiment uses Omron's 1mm optical fiber sensor as the detection probe for sensing incoming materials. Compared with ordinary sensors and photoelectric switches, the optical fiber sensor has a smaller volume, a smaller detection area (1mm), and a higher sensitivity, ensuring that the signal delay error of the workpiece when passing through the sensor is small, while improving the scanning cycle of the PLC internal cycle, which can ensure the repeated positioning accuracy of the equipment printing. In short, the speed of the workpiece moving on the conveyor belt 25 is fixed, ensuring the time for the workpiece to pass through the sensor to the nozzle 4 each time, thereby ensuring the repeated positioning accuracy of the printing.

[0065] The principle of equipment printing: the workpiece sends out a photoelectric signal after passing through the sensor. After receiving the signal, the equipment delays for a period of time (waiting for the workpiece to move to the position of the nozzle 4) before spraying out the ink. When the printing is offset during the processing of the equipment, it is necessary to adjust the position of the printing mark by modifying the delay parameters. In order to facilitate the workers to debug the parameters, a set of algorithm programs that associate time and distance are developed by using macro instructions (similar to C language) in the HMI to realize the automatic association between the printing correction distance and the delay time, which is convenient for actual workers to operate. In order to improve the accuracy of the equipment's statistical production, accurate to year / month / day / hour, a statistical production program is developed by using macro instructions (similar to C language) in the HMI, so that the equipment can view the production of every hour of the day, the production of every day of the month, and the production of every month of the year.
