[0043] For example, Figure 1As shown, two transport lines 111 can be arranged side by side on the machine body 110, and the two transport lines 111 can be extended in the front-rear direction; a storage area 140 and a conveying area 150 are provided on the transport line 111, and the conveying area 150 can be located in front of the storage area 140; a plurality of tray racks 120 can be stored on the right transport line 111, and a plurality of tray racks 120 can be stored in the storage area 140; a limiting area with an upper opening is formed in the tray rack 120, and a plurality of trays are stacked up and down in the limiting area; a conveying assembly 130 can be arranged on the machine body 110 and located on one side of the transport line 111, and each transport line 111 can correspond to a conveying assembly 130. When the docking station 100 is working, the AGV cart 200 can dock with the docking station 100, and a plurality of tray racks 120 loaded with blanks are placed in the storage area 140 of the right transport line 111. The right transport line 111 transports one of the tray racks 120 in the storage area 140 to the handling area 150, and the left handling component 130 transports the tray rack 120 loaded with finished workpieces on the AGV cart 200 to the handling area 150 of the left transport line 111. At the same time, the right handling component 130 transports the tray rack 120 in the handling area 150 to the AGV cart 200. Furthermore, the AGV trolley 200 can receive the material tray rack 120 on the docking platform 100 to realize the transportation of multiple material trays, so that the AGV trolley 200 and the docking platform 100 can realize the handling of multiple material trays at one time to meet the loading and unloading needs of multiple CNC machine tools, reduce the docking frequency of the AGV trolley 200 and the docking platform 100, and improve the processing efficiency of the CNC machine tool group.

[0044] Furthermore, the tray rack 120 includes a bottom plate 121 and a plurality of stoppers 122, the stoppers 122 are arranged at intervals along the edge of the bottom plate 121, and the stoppers 122 and the bottom plate 121 surround and form a stop zone. Figure 2 As shown, the chassis 121 can be rectangular, and a stopper 122 is installed at each of the four corners of the rectangular bottom plate. The chassis 121 and the four stoppers 122 surround and form a stopper area, and the opening of the stopper area faces upward. Furthermore, multiple trays can be stacked up and down in the stopper area.

[0045] In some embodiments of the present invention, the transport assembly 130 is disposed below the transport line 111. The transport assembly 130 includes an adjustment structure and a support plate 134. The adjustment structure includes a first driver 131, a guide rail 132, and a second driver 133. The output end of the first driver 131 is connected to the guide rail 132. The support plate 134 is slidably disposed on the guide rail 132. The first driver 131 is used to drive the guide rail 132 to perform lifting movements, so that the support plate 134 carries and drives the material tray rack 120 in the storage area 140 to perform lifting movements. The output end of the second driver 133 is connected to the support plate 134 and is used to drive the support plate 134 to slide along the guide rail 132, so that the support plate 134 drives the material tray rack 120 to move to the AGV trolley 200. For example, Figure 2 As shown, the transport assembly 130 can be arranged directly below the transport area 150; the guide rail 132 can extend in the front-rear direction, the output end of the first driver 131 is connected to the bottom end of the guide rail 132, the second driver 133 is fixedly mounted on the guide rail 132, and the support plate 134 is slidably mounted on the guide rail 132. After the AGV trolley 200 is docked with the docking station 100, the transport line 111 can transport the material tray rack 120 in the storage area 140 to the transport area 150, the first driver 131 can drive the guide rail 132 to move upward, and then the support plate 134 can carry the material tray rack 120 in the transport area 150 and drive the material tray rack 120 to rise to a certain height, then the second driver 133 can drive the support plate 134 to move forward along the guide rail 132, at this time, the support plate 134 can drive the material tray rack 120 to move forward, so that the material tray rack 120 moves to the AGV trolley 200. By using the conveying component 130 to realize the conveying of the material tray rack 120 between the conveying area 150 and the AGV cart 200, the complexity of the manipulator on the AGV cart 200 can be reduced, and the area on the AGV cart 200 for storing the material tray rack 120 can be increased, so that the AGV cart 200 can convey more material trays at a time, thereby reducing the frequency of docking between the AGV cart 200 and the docking platform 100, so as to improve the processing efficiency of the CNC machine tool group.

[0046] Specifically, the first driver 131 and the second driver 133 may both be cylinders.

[0047] In some embodiments of the present invention, reference Figure 1 and Figure 3Two limiting structures 160 are provided on the transport line 111, and a storage area 140 is formed between the two limiting structures 160. The limiting structures 160 can prevent the tray racks 120 from entering or leaving the storage area 140. A plurality of tray racks 120 are stored in the storage area 140. By providing the limiting structures 160, after the transport line 111 drives a tray rack 120 to move from the storage area 140 to the handling area 150, the limiting structures 160 can restrict the subsequent tray racks 120 from continuing to enter the handling area 150, thereby improving the problem of multiple tray racks 120 entering the handling area 150 at one time.

[0048] Specifically, refer to Figure 3 The limiting structure 160 includes a third driver 161 and abutment 162. The output end of the third driver 161 is connected to the abutment 162. The third driver 161 is arranged on the side of the transport line 111. Under the drive of the third driver 161, the abutment 162 can move toward the middle of the transport line 111 to block the tray rack 120 from entering or leaving the storage area 140. When the tray rack 120 needs to enter or exit the storage area 140, the third driver 161 can drive the abutment 162 to move in the left and right directions to move away from the middle of the transport line 111, so that the tray rack 120 can freely enter or leave the storage area 140; when it is necessary to restrict the tray rack 120 from entering or leaving the storage area 140, the third driver 161 can drive the abutment 162 to approach the middle of the transport line 111. At this time, the abutment 162 can block the tray rack 120 from moving along the transport line 111.

[0049] Furthermore, the limiting structure 160 may include two third drivers 161 and two abutment members 162, the third drivers 161 correspond to the abutment members 162 one by one, and the two third drivers 161 are respectively arranged on the left and right sides of the transport line 111. Under the drive of the third drivers 161, the abutment members 162 can move in the left and right directions to approach or move away from the middle of the transport line 111.

[0050] The production line according to the second embodiment of the present invention comprises the docking station 100 according to the first embodiment of the present invention.

[0051] In some embodiments of the invention, reference Figure 1The production line also includes an AGV trolley 200 and a CNC machine tool group; the AGV trolley 200 includes a trolley body 210 and a handling robot 220, the handling robot 220 is arranged on the trolley body 210, and a carrying area 230 is provided on the trolley body 210; the CNC machine tool group includes a plurality of CNC machine tools; wherein the trolley body 210 is provided with a walking mechanism so that the AGV trolley 200 can be docked with the docking station 100 or each CNC machine tool respectively, when the AGV trolley 200 is docked with the docking station 100, the handling assembly 130 can drive the material tray rack 120 to move between the handling area 150 and the carrying area 230, when the AGV trolley 200 is docked with the CNC machine tool, the handling robot 220 can drive the material tray to move between the CNC machine tool and the carrying area 230. Furthermore, driven by the traveling mechanism, the AGV trolley 200 can dock with the docking platform 100 to receive the tray rack 120 loaded with blanks on the docking platform 100. Then, driven by the traveling mechanism, the AGV trolley 200 can dock with the idle CNC machine tool. The AGV trolley 200 can receive the tray loaded with finished workpieces in the CNC machine tool, and transport the tray loaded with blanks to the CNC machine tool, until all the trays loaded with blanks on the AGV trolley 200 are transported into the CNC machine tool for processing.

[0052] Reference Figure 4 According to the processing method of the third aspect of the present invention, which is applied to the production line provided by the second aspect of the present invention, the processing method includes but is not limited to the following steps:

[0053] Step S100: a reset step, resetting the AGV 200 so that the unloaded portion of the load-bearing area 230 forms a first station, and the portion of the load-bearing area 230 carrying the unloaded material tray rack 120 forms a second station;

[0054] It can be understood that the first station is used to receive the tray rack 120 fully loaded with blanks on the docking station 100, and the empty tray rack 120 on the second station is used to receive the tray loaded with finished workpieces in the CNC machine tool.

[0055] Step S200: a blank transfer step, in which the material tray rack 120 loaded with blanks in the transfer area 150 is transferred to the first station;

[0056] Step S300: loading and unloading step, driving the AGV 200 to move, and docking the AGV 200 with the CNC machine tool, so that the tray loaded with finished products on the CNC machine tool is transported to the empty tray rack 120 at the second station, and the tray in the tray rack 120 at the first station is transported to the CNC machine tool;

[0057] Step S400: a transfer docking step, in which the state of the tray rack 120 in the first station on the AGV 200 is judged. If the tray rack 120 in the first station on the AGV 200 is in an unloaded state, the AGV 200 is driven to dock with the docking station 100;

[0058] Step S500: Finished workpiece transfer step, moving the tray rack 120 on the second station to the transfer area 150;

[0059] It can be understood that when the material tray rack 120 in the first workstation on the AGV trolley 200 is in an empty state, the material tray rack 120 in the second workstation on the AGV trolley 200 is full of finished workpieces. At this time, the AGV trolley 200 needs to dock with the docking platform 100 to unload the material tray rack 120 on the second workstation on the AGV trolley 200 to the docking platform 100.

[0060] Step S600: repeat the above-mentioned resetting step, blank transfer step, loading and unloading step, transfer docking step and finished workpiece transfer step until all the blanks on the docking station 100 are processed.

[0061] It can be understood that after repeating the resetting step, the blank transfer step, the loading and unloading step, the transfer docking step and the finished workpiece transfer step, the blanks in the loading tray rack 120 of the docking platform 100 can be gradually processed into finished workpieces, and the AGV trolley 200 can transport the blanks on the docking platform 100 to an idle CNC machine tool for processing, and transport the finished workpieces in the CNC machine tool to the docking platform 100. Through the cooperation of the docking platform 100 and the AGV trolley 200, loading and unloading of the CNC machine tool group is realized, thereby improving the processing efficiency of the CNC machine tool group.

[0062] In some embodiments of the present invention, reference Figure 5 In step S200, the following steps are included but are not limited to:

[0063] Step S210: driving the material tray rack 120 to move from the storage area 140 to the transport area 150;

[0064] Step S220: transporting the material tray rack 120 in the transport area 150 to the first station through the transport assembly 130.

[0065] It can be understood that a plurality of tray racks 120 loaded with blanks are stored in the storage area 140, and the transport line 111 can drive the tray racks 120 in the storage area 140 close to the handling area 150 to move so that the tray racks 120 move into the handling area 150, and then, the first driver 131 can drive the guide rail 132 to move upward so that the support plate 134 on the guide rail 132 supports the tray racks 120 in the handling area 150, and then, the second driver 133 can drive the support plate 134 to move forward along the guide rail 132 to transport the tray racks 120 loaded with blanks to the first workstation of the AGV trolley 200. Furthermore, after the AGV trolley 200 is docked with the docking station 100, the docking station 100 can automatically transport the material tray rack 120 carrying the blanks to the first workstation of the AGV trolley 200, thereby simplifying the structure of the transport robot 220 on the AGV trolley 200 to increase the space on the AGV trolley 200 for storing the material tray rack 120, thereby improving the transport efficiency of the AGV trolley 200.

[0066] In some embodiments of the present invention, reference Figure 6 In step S300, the following steps are included but are not limited to:

[0067] Step S310: Acquire status information of each CNC machine tool in the CNC machine tool group;

[0068] Step S320: according to the status information of each CNC machine tool, drive the AGV 200 to move to the CNC machine tool in an idle state, and dock the AGV 200 with the CNC machine tool;

[0069] Step S330: transport the tray containing the finished product in the CNC machine tool to the tray rack 120 on the second station, and transport the tray in the tray rack 120 on the first station to the CNC machine tool.

[0070] It is understandable that the production line also includes a controller, which is electrically connected to the AGV trolley 200 and the CNC machine tool respectively. The CNC machine tool group includes multiple CNC machine tools. When there is a CNC machine tool that has completed processing, the CNC machine tool can transmit the status information to the controller, and then the controller can obtain the position of the idle CNC machine tool. The controller can control the AGV trolley 200 to move to the idle CNC machine tool and dock with the idle CNC machine tool. Then, the AGV trolley 200 can take out the carrier plate carrying the finished workpiece in the idle CNC machine tool, and move the carrier plate carrying the blank on the AGV trolley 200 to the CNC machine tool. Then, the AGV trolley 200 can obtain the information of the idle CNC machine tool in time, and complete the unloading of the finished workpiece and the loading of the blank in the idle CNC machine tool in time, so as to improve the processing efficiency of the CNC machine tool group.
