[0031] The rack 101 can be arranged on the transmission mechanism 2, the rack 101 is built by aluminum alloy, forms a light and stable bearing frame, and is used for bearing a plurality of trays 102. The tray 102 is made of injection molding process, is designed with a plurality of specifications of placing grooves and suction interfaces. The plurality of specifications of the placing grooves of the tray 102 are optimized and designed according to the size and shape of the substrate, ensure that the substrate does not shift or tilt during the placing process, and the structure is as shown in Figure 12 and Figure 13 .

[0032] When the rack 101 is placed on the first conveying line 211, the first driving assembly 2113 drives the rack 101 to stop at the first stop device 2114, and the first check device 2116 is immediately raised to prevent the rack 101 from sliding backward. The lifting conveying line 33 is connected with the first conveying line 211 under the drive of the servo motor 321, and after the first stop device 2114 is lowered, the first driving assembly 2113 continues to drive the rack 101 to move to the lifting conveying line 33, and the third check device 334 is immediately raised to fix the position of the rack 101. At this time, the rack 101 has completed the transfer from the first conveying line 211 to the lifting conveying line 33. The lifting conveying line 33 is raised to the specified height under the drive of the servo motor 321, the feeding device 2127 is started and the tray 102 is taken out from the rack 101, and then it is pushed to the roller 47 on the fourth main support 43. The tray 102 rolls along the roller 47 until it touches the third stop device 44, and after the feeding device 2127 returns to the original position, the limiting device 45 is started and the tray 102 is centered and positioned by the limiting rod 454. At this time, the tray 102 is ready for the sample preparation process. After the sample preparation is completed, the tray 102 is put back on the fourth main support 43, and the limiting device 45 is started again to ensure the accurate position of the tray 102. Then, the push device 46 is started and the tray 102 is pushed back to the original position in the rack 101, so as to ensure the consistency of the position of the tray 102 in the rack 101 before and after the sample preparation. After the lifting conveying line 33 is raised to be connected with the second conveying line 212, the third driving assembly 333 drives the rack 101 to the second driving assembly 2123, the rack 101 moves to the second stop device 2124 and stops, and the second check device 2126 is immediately raised to prevent the rack 101 from sliding backward, completing the whole sample preparation process.

[0033] In order to enable those skilled in the art to better understand and implement the present application, the specific implementation principles of the present application are further described below in conjunction with a specific application scenario.

[0034] Firstly, the substrate is manually placed in the placing groove of the tray 102, and the tray 102 is stacked on the rack 101. The full tray 102 is placed on the first conveying line 211, and the first transmission assembly 2113 starts to operate under the drive of the first driving unit 2112. The first transmission assembly 2113 pushes the rack 101 to move along the length direction of the first main support 2111 by friction. When the rack 101 approaches the first stop device 2114, the first distance measuring sensor 2115 detects the position of the rack 101 in real time and transmits the signal to the control system. When the rack 101 reaches the specified position, the controlled first non-return device 2116 is lifted by the pneumatic push rod to prevent the rack 101 from continuing to advance. At the same time, the first stop device 2114 with a spring mechanism automatically resets to prevent the rack 101 from sliding back due to inertia. At this time, the position of the rack 101 on the first conveying line 211 is accurately fixed.

[0035] Subsequently, the lifting conveying line 33 moves along the slide rail 323 under the drive of the servo motor 321 and is connected with the first conveying line 211. After the connection is completed, the first stop device 2114 is lowered, the first transmission assembly 2113 is restarted, and the rack 101 is pushed onto the lifting conveying line 33. The third non-return device 334 is immediately lifted to fix the position of the rack 101, and the third main support 331 limits the rack 101. The lifting conveying line 33 is accurately controlled by the lead screw 322 and is lifted in the vertical direction to the height of the connection with the second conveying line 212. The height distance between the inductive devices 51 is consistent with the height distance between the trays 102. In this process, the inductive devices 51 are used in cooperation with the inductive sheets 52 to ensure the accuracy of the lifting height, so as to adapt to the transmission requirements of different specifications of the rack 101.

[0036] When the lifting conveying line 33 is connected with the feeding platform 4, the feeding device 2127 is started. The electric push rod pushes the electric suction cup to approach the tray 102, the vacuum generator generates negative pressure, and the electric suction cup firmly adsorbs the tray 102. Subsequently, the electric push rod takes out the tray 102 from the rack 101 and pushes it to the roller 47 on the fourth main support 43. The tray 102 rolls on the roller 47 until it touches the third stop device 44 to stop. After the feeding device 2127 returns to the original position, the limiting device 45 is started. The electric sliding block 452 is an integrated driving component, which moves linearly along the guide rail 451 under the drive of the built-in motor, drives the limiting frame 453 and the limiting rod 454 to move to the center of the tray 102. The limiting rod 454 is connected with the fourth main support 43 through the linear bearing to ensure smooth movement and no jamming phenomenon, so as to realize the center positioning of the tray 102. After the positioning is completed, the external automatic grabbing mechanism transfers the tray 102 to the sample preparation station for sample preparation.

[0037] After the sample preparation process is completed, the tray 102 is placed back on the fourth main support 43. The limiting device 45 is activated again to ensure the accurate position of the tray 102. Then the push-back device 46 is activated, and the second electric sliding block moves linearly along the second guide rail under the drive of the built-in motor, and drives the flexible push block to push the tray 102 back to the original position in the rack 101. The flexible push block is made of silica gel material, which avoids damaging the surface of the tray 102 and ensures the stability of the pushing process. Then the lifting conveying line 33 continues to rise to the next tray 102 flush with the feeding platform 4, and the above steps are repeated until all the trays 102 on the rack 101 are completed.

[0038] After all the trays 102 on the rack 101 are completed, the lifting conveying line 33 rises to the second conveying line 212 and is connected, the third check valve 334 is lowered, and the third transmission assembly 333 is activated, while the rack 101 is pushed onto the second transmission assembly 2123. The second transmission assembly 2123 drives the rack 101 to move to the second stop device 2124 and stop, and the second check valve 2126 is raised to prevent the rack 101 from sliding backward, and the whole sample preparation process is completed. The external logistics trolley is connected with the second conveying line 212, and after pressing the material taking button, the second check valve 2126 is lowered, and the rack 101 is taken from the second conveying line 212 to complete the unloading. Then the lifting conveying line 33 is lowered and connected with the first conveying line 211, and the second rack 101 flows into the first conveying line 211, and the above steps are repeated to complete the sample preparation.

[0039] Through the above steps, it can be seen that through the cooperation of various components, the automatic transmission, accurate positioning and efficient recycling and storage of the rack 101 and the tray 102 are realized. Among them, the design of the stop device and the check valve effectively prevents the deviation or backward sliding of the rack 101 and the tray 102 during the transmission process; the limiting device 45 ensures the consistency of the position of the tray 102 through the linear motion of the limiting rod; and the push-back device 46 takes into account the protection of the tray and the pushing accuracy through the design of the flexible push block. These designs together improve the efficiency and accuracy of the building coating test plate sample preparation, reduce manual intervention, and optimize the substrate management process.
