[0015] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0016] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0017] Example 1: As Figure 1 - Figure 4 As shown, this utility model provides an automated material transfer device for printing electrical panels, including a printing mechanism 1. A material transfer mechanism 2 is provided on one side of the printing mechanism 1. The material transfer mechanism 2 includes a fixed frame 21, a material carrier 22, a cylinder 23, a limiting plate 24, and a clamping plate 25. A servo motor 3 is installed on the inner wall of the fixed frame 21. The material carrier 22 is rotatably installed on the top surface of the fixed frame 21. The output shaft end of the servo motor 3 is fixedly connected to the center of the bottom surface of the material carrier 22. Four limiting plates 24 are provided and are arranged in a circular row on the top surface of the material carrier 22. The cylinder 23 is fixedly installed on the top surface of the material carrier 22. The clamping plate 25 is fixedly connected to the end of the telescopic rod of the cylinder 23.

[0018] The specific settings and functions of this embodiment are described in detail below. The material carrier 22 serves as a platform for supporting the electrical panel. Its top surface cooperates with the limiting plate 24 and the clamping plate 25 to achieve panel positioning and clamping. By being fixedly connected to the output shaft of the servo motor 3, it can rotate with the servo motor 3 to achieve circumferential material transfer, transporting the panel from the loading position to the printing position, and then from the printing position to the unloading position, realizing automated and high-precision material transfer, avoiding the errors and low efficiency of manual material transfer. Four limiting plates 24 are set and installed in a circumferential row on the top surface of the material carrier 22. The adjacent limiting plates 24 form a positioning area that matches the size of the electrical panel, which can circumferentially limit the electrical panel placed on the material carrier 22, prevent the panel from shifting during material transfer or printing, and ensure the accuracy of the subsequent printing position.

[0019] Example 2: Figure 1 - Figure 4 As shown, the printing mechanism 1 includes a support frame 11, a connecting frame 12, a cylinder 13, a traction block 14, a printing screen 15, and a connecting platform 16. The connecting frame 12 is movably installed on the inner wall of the support frame 11. The printing screen 15 is fixedly installed on the bottom surface of the connecting frame 12. The cylinder 13 is installed on the end face of the connecting frame 12. The traction block 14 is slidably connected to the inner wall of the connecting frame 12. The traction block 14 is fixedly connected to the end of the telescopic rod of the cylinder 13. The connecting platform 16 is fixedly connected to the outer wall of the traction block 14. A second cylinder 161 is installed on the bottom surface of the connecting platform 16. The bottom end of the telescopic rod of the second cylinder 161 is fixedly connected to a connecting rod. A connecting plate 162 is fixedly connected to a scraper 163 on its bottom surface. A guide rod 17 is fixedly connected to the inner wall of the support frame 11. The back of the connecting frame 12 is movably sleeved on the outer wall of the guide rod 17. A cylinder 18 is installed on the inner bottom surface of the support frame 11. The top end of the telescopic rod of the cylinder 18 is fixedly connected to the back of the connecting frame 12. A fixing plate 26 is fixedly connected to the side wall of the fixing frame 21. A cylinder 27 is installed on the top surface of the fixing plate 26. A limit block 28 is fixedly connected to the end of the telescopic rod of the cylinder 27. A slot 29 is opened on the side wall of the loading platform 22. The limit block 28 is inserted into the inner wall of the slot 29.

[0020] The overall effect of this embodiment is that cylinder 18, through the extension and retraction of the telescopic rod, drives the connecting frame 12 to rise and fall along the guide rod 17, which can flexibly adjust the distance between the printing screen 15 and the panel: before printing, the printing screen 15 is brought close to the panel surface to ensure that the ink can fully penetrate the panel; after printing, the printing screen 15 is quickly moved away from the panel to avoid friction between the screen and the panel, which could cause smudging of the printed pattern or scratches on the panel surface. Cylinder 13 drives the traction block 14 to slide horizontally along the inner wall of the connecting frame 12. The traction block 14 drives the connecting table 16 and the scraper 163 to move synchronously, which can control the scraping speed and stroke of the scraper 163. The stroke matches the length of the printing screen 15 to ensure that the ink can evenly cover the screen pattern area. In the printing mechanism 1, cylinder 2161 adjusts the height of connecting plate 162 to control the contact pressure between scraper 163 and printing screen 15, ensuring clear printing patterns without omissions or overprints. The temporary fixing structure of the material carrier 22 is formed by fixing plate 26, cylinder 527 and limiting block 28: when the material carrier 22 drives the panel to the printing position, cylinder 527 pushes the limiting block 28 to insert into the slot 29 on the side wall of the material carrier 22, realizing the positioning and locking of the material carrier 22, preventing the material carrier 22 from rotating during the printing process and causing printing misalignment, further improving printing accuracy. After printing is completed, all components of the printing mechanism 1 are reset, the limiting block 28 is disengaged from the slot 29, and the material transfer mechanism 2 then rotates the panel to the unloading position.

[0021] The operating method and working principle of this device are as follows: In the initial state, the loading platform 22 is in the position to be loaded, and cylinders 23, 27, 161, and 18 are all in the retracted state. The scraper 163 is away from the printing screen 15, and the printing screen 15 is in a high position. The electrical panel to be printed is placed between the four limiting plates 24 on the top surface of the loading platform 22, and the device is started. The telescopic rod of cylinder 23 extends, pushing the clamping plate 25 to clamp the panel, completing the panel fixing. The servo motor 3 starts, driving the loading platform 22 to rotate along the top surface of the fixing frame 21 until the panel moves to the printing position directly below the printing mechanism 1. The telescopic rod of cylinder 27 extends, pushing the limiting block 28 into the slot 29 of the loading platform 22, locking the loading platform 22. The telescopic rod of cylinder 18 extends, driving the connecting frame 12 to move downward along the guide rod 17, so that the printing screen 15 adheres to the surface of the panel. The telescopic rod of cylinder 2 161 extends, pushing the scraper 163 downward to adhere to the printing screen 15; simultaneously, the telescopic rod of cylinder 1 13 extends, driving the traction block 14, connecting platform 16, and scraper 163 to move along the connecting frame 12, and the scraper 163 scrapes over the printing screen 15 to complete the panel printing; after printing, the telescopic rod of cylinder 2 161 retracts, driving the scraper 163 away from the printing screen 15; the telescopic rod of cylinder 1 13 retracts, driving the scraper 163 to reset; the telescopic rod of cylinder 3 18 retracts, driving the connecting frame 12 and the printing screen 15 to reset upward; the telescopic rod of cylinder 5 27 retracts, driving the limit block 28 to disengage from the slot 29, unlocking the loading platform 22; the servo motor 3 starts again, driving the loading platform 22 to rotate to the unloading position, the telescopic rod of cylinder 4 23 retracts, releasing the panel and completing the unloading; then the loading platform 22 rotates back to the waiting position to enter the next work cycle.

[0022] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields.
