[0095] Further, as shown in Figure 6 and Figure 7 As shown, the transfer trolley 3c includes a first mobile base 31c and a grabbing device 32c, the grabbing device 32c is arranged on the first mobile base 31c, and the grabbing device 32c is used for grabbing and transferring the workpieces 7c, so that the first mobile base 31c can drive the grabbing device 32c to move flexibly, for example, to approach the position of the transferred workpieces 7c, thereby reducing the difficulty of the grabbing device 32c transferring the workpieces 7c. In addition, the material transfer trolley 6c includes a second mobile base 61c and a temporary storage support 62c, the temporary storage support 62c is arranged on the second mobile base 61c, and the workpieces 7c are adapted to be placed on the temporary storage support 62c. That is, the temporary storage support 62c can temporarily store the workpieces 7c, and the second mobile base 61c can drive the temporary storage support 62c to move flexibly, for example, when the temporary storage support 62c temporarily stores the workpieces 7c to be processed, the second mobile base 61c can drive the temporary storage support 62c to the feeding position of the automatic feeding and discharging system 100c, and the second mobile base 61c can also drive the temporary storage support 62c to the discharging position of the automatic feeding and discharging system 100c to receive the processed workpieces 7c, and after the workpieces 7c are loaded, the second mobile base 61c can drive the temporary storage support 62c to move to carry away the processed workpieces 7c. Optionally, the first mobile base 31c can be an AGV (automatic guided vehicle), and the second mobile base 61c can be an AGV (automatic guided vehicle) or a trolley.

[0096] The workpieces 7c temporarily stored on the material transport trolley 6c are suitable to be sequentially transferred by the transfer trolley 3c to the feeding and discharging platform 2c and then conveyed to the buffer platform 1c through the feeding and discharging platform 2c.

The grabbing device 32c grabs the processed workpieces 7c on the conveying station 23c and transfers and conveys the processed workpieces 7c to the temporary storage bracket 62c of the material transport trolley 6c. When the number of the processed workpieces 7c on the temporary storage bracket 62c reaches a certain amount, the second moving base 61c drives the temporary storage bracket 62c to move to carry away the processed workpieces 7c, so as to realize automatic discharging of the processed workpieces 7c.

[0100] It should be noted that the material transfer trolley 6c can be one, that is, the material transfer trolley 6c can temporarily store and carry the workpiece 7c to be processed and also temporarily store and carry the processed workpiece 7c, which is beneficial to reduce the number of material transfer trolleys 6c, thereby saving the investment cost of the automatic feeding and discharging system 100c. Of course, the material transfer trolley 6c can also be provided with multiple material transfer trolleys 6c, which include a material transfer trolley 6c for temporarily storing and carrying the workpiece 7c to be processed and a material transfer trolley 6c for temporarily storing and carrying the processed workpiece 7c, which is beneficial to improve the carrying efficiency of the workpiece 7c.

[0101] According to the automatic feeding and discharging system 100c of the embodiment of the present application, the workpiece 7c is transferred between the material transfer trolley 6c and the feeding and discharging platform 2c through the transfer trolley 3c, and the feeding and discharging platform 2c and the buffer platform 1c can transfer the workpiece 7c to each other, so that the automatic feeding and discharging of the workpiece 7c can be realized, the labor intensity of the workpiece 7c in the processing process is reduced, the production and processing efficiency of the workpiece 7c is improved, the labor cost is reduced, and the safety of production is improved to a certain extent.

The number of conveying stations 23c is the same as and corresponds to the number of buffer stations 12c of each buffer bin 11c.

[0103] That is, the feeding and discharging platform 2c and the buffer platform 1c can be arranged along the first direction S1, and in the second direction S2, the conveying station 23c can correspond to the buffer station 12c one by one, so that the conveying station 23c can convey the workpiece 7c to be processed to the corresponding buffer station 12c along the first direction S1, and the buffer station 12c can convey the processed workpiece 7c to the corresponding conveying station 23c along the opposite direction of the first direction S1, which is beneficial to reduce the difficulty of transferring the workpiece 7c between the conveying station 23c and the buffer station 12c.

[0104] In addition, during the feeding process of the workpieces 7c to be processed, the transfer trolley 3c can sequentially transfer the workpieces 7c to be processed on the transport trolley 6c to all the conveying stations 23c, and after the workpieces 7c to be processed are placed on all the conveying stations 23c, the driving module 22c drives the plurality of conveying stations 23c to synchronously convey the plurality of workpieces 7c to be processed on the plurality of conveying stations 23c to all the storage stations 12c on one of the layers of the storage platform 1c; during the discharging process of the workpieces 7c processed, all the storage stations 12c on one layer of the storage magazine 11c can synchronously convey the workpieces 7c processed and stored to all the conveying stations 23c of the feeding and discharging platform 2c. Therefore, the feeding and discharging efficiency of the workpieces 7c is improved.

[0105] According to some embodiments of the present application, as shown in Figure 4 and Figure 8 The storage platform 1c comprises a first support frame 13c, a storage mechanism 14c and a first lifting mechanism 15c, the storage mechanism 14c comprises a plurality of layers of storage magazines 11c arranged in sequence in the up-down direction, and the first lifting mechanism 15c is arranged on the first support frame 13c and connected with the storage mechanism 14c to drive the storage mechanism 14c to lift. That is, the height position of the plurality of layers of storage magazines 11c is adjustable, which facilitates to reduce the difficulty of conveying the workpieces 7c to the storage magazine 11c and the difficulty of outputting the workpieces 7c from the storage magazine 11c.

[0106] Specifically, when the feeding and discharging platform 2c conveys the workpieces 7c to be processed to the storage platform 1c, the first lifting mechanism 15c can drive the storage mechanism 14c to lift, so that one of the layers of storage magazines 11c is docked with the feeding and discharging platform 2c, and the workpieces 7c to be processed are conveyed to the plurality of storage stations 12c of the layer of storage magazines 11c through the conveying stations 23c; after all the storage stations 12c on the layer store the workpieces 7c, the first lifting mechanism 15c can control the storage mechanism 14c to lift, so that the idle storage magazine 11c is docked with the feeding and discharging platform 2c, and the above process is repeated until all the storage stations 12c store the workpieces 7c to be processed; when the storage platform 1c conveys the workpieces 7c processed to the feeding and discharging platform 2c, the first lifting mechanism 15c can first drive the storage mechanism 14c to lift, so that one of the layers of storage magazines 11c is docked with the feeding and discharging platform 2c, and the workpieces 7c processed are conveyed to the plurality of conveying stations 23c through the plurality of storage stations 12c on the layer of storage magazines 11c; after the workpieces 7c processed on all the storage stations 12c of the layer of storage magazines 11c are conveyed, the first lifting mechanism 15c drives the storage mechanism 14c to lift, so that the other storage magazines 11c storing the workpieces 7c processed are sequentially docked with the feeding and discharging platform 2c, so as to output all the workpieces 7c processed on the storage platform 1c.

[0107] According to some embodiments of the present application, each buffer station 12c comprises a buffer base plate 121c and a transmission assembly 122c arranged on the buffer base plate 121c and used for transmitting the workpiece 7c, and further comprises an auxiliary support 123c arranged on the buffer base plate 121c and located on opposite sides of the transmission assembly 122c, the auxiliary support 123c comprising a support block 124c extending along the transmission direction of the transmission assembly 122c and a plurality of support wheels 125c arranged on the support block 124c and spaced along the extension direction of the support block 124c. That is, the workpiece 7c can be placed on the auxiliary support 123c and the transmission assembly 122c, the side of the workpiece 7c facing the buffer base plate 121c is located on the transmission assembly 122c and the support wheels 125c, the workpiece 7c is in rolling contact with the support wheels 125c, the transmission assembly 122c conveys the workpiece 7c along the transmission direction, and the auxiliary supports 123c located on both sides of the transmission assembly 122c prevent the workpiece 7c from overturning relative to the transmission direction while the workpiece 7c pushing the support wheels 125c to roll can better reduce the friction in the conveying of the workpiece 7c, thereby improving the stability of the transmission of the workpiece 7c and reducing the driving force required for the transmission of the workpiece 7c.

[0108] In some embodiments of the present application, the transmission assembly 122c is two groups of belt conveying mechanisms 10a spaced along the conveying direction perpendicular to the transmission direction of the transmission assembly 122c, each group of belt conveying mechanisms 10a comprising a conveying belt 101a and a driving wheel 102a and a driven wheel 103a, the driving wheel 102a and the driven wheel 103a being arranged along the conveying direction of the transmission assembly 122c and rotatably arranged on the buffer base plate 121c, the conveying belt 101a being arranged around the driving wheel 102a and the driven wheel 103a, the buffer base plate 121c being provided with a guide groove arranged between the two groups of belt conveying mechanisms 10a, the extension direction of the guide groove being consistent with the conveying direction of the transmission assembly 122c, the workpiece 7c being provided with two pins matched with the guide groove, the driving wheels 102a of the two groups of belt conveying mechanisms 10a being connected through a transmission connecting shaft 104a, each layer of transmission assembly 122c being provided with a driving motor 105a corresponding to the transmission connecting shaft 104a, and the transmission connecting shaft 104a is driven to rotate by the driving motor 105a to drive the two belt conveying mechanisms 10a to rotate synchronously.

[0109] According to some embodiments of the present application, as Figure 9As shown, the conveying station 23c comprises a conveying bottom plate 231c, an upper and lower conveying assembly 232c and a cushion assembly 233c. The conveying bottom plate 231c is arranged on the conveying table 21c, and the upper and lower conveying assembly 232c is arranged on the conveying bottom plate 231c. The driving module 22c is connected with the upper and lower conveying assembly 232c of all the conveying stations 23c to drive the upper and lower conveying assembly 232c of all the conveying stations 23c to synchronously convey the workpiece 7c. The cushion assembly 233c comprises two cushions 234c arranged on opposite sides of the upper and lower conveying assembly 232c to support the edges of the workpiece 7c. That is, when the workpiece 7c is placed on the conveying station 23c, the side of the workpiece 7c facing the conveying bottom plate 231c is located on the upper and lower conveying assembly 232c and the cushions 234c. The upper and lower conveying assembly 232c conveys the workpiece 7c along the conveying direction, and the cushions 234c arranged on the two sides of the upper and lower conveying assembly 232c can effectively prevent the workpiece 7c from overturning relative to the conveying direction of the upper and lower conveying assembly 232c, thereby improving the stability of conveying the workpiece 7c by the conveying station 23c. In addition, all the upper and lower conveying assemblies 232c share the driving module 22c, which can better reduce the number of driving modules 22c, save the investment cost of the upper and lower conveying platform 2c, better ensure the synchronization of the plurality of upper and lower conveying assemblies 232c, and has low maintenance difficulty.

[0110] In the embodiment, each upper and lower conveying assembly 232c of each conveying station 23c can be individually connected with one driving module 22c. That is, each upper and lower conveying assembly 232c of each conveying station 23c corresponds to an independent driving module 22c. Thus, the driving module 22c drives the corresponding upper and lower conveying assembly 232c to convey the workpiece 7c, so that each conveying station 23c can independently convey the workpiece 7c. When part of the driving modules 22c fails, the remaining driving modules 22c can normally operate, thereby avoiding interference between the plurality of conveying stations 23c, and improving the reliability of the upper and lower conveying platform 2c.

[0111] Further, the adjacent sides of the two adjacent conveying stations 23c are provided with a partition plate 235c between the adjacent pads 234c, the upper end surface of the partition plate 235c is higher than the upper surface of the pad 234c, and the partition plate 235c is used to limit the deviation of the workpiece 7c in the conveying direction. That is, the two adjacent conveying stations 23c can be spaced apart by the partition plate 235c, and the workpiece 7c is limited on both sides by the partition plate 235c on both sides of the conveying station 23c, so that the workpiece 7c is always located between the partition plates 235c during conveying, thereby limiting the conveying direction of the workpiece 7c. For example, when the conveying station 23c is connected to the buffer station 12c, the workpiece 7c to be machined on the conveying station 23c can accurately enter the corresponding buffer station 12c, or the machined workpiece 7c on the buffer station 12c can accurately enter the corresponding conveying station 23c, thereby achieving accurate conveying of the workpiece 7c. In addition, the partition plate 235c can better space the workpieces 7c on the conveying stations 23c on both sides, thereby avoiding interference when the two adjacent conveying stations 23c convey the workpieces 7c, and facilitating the stability of the workpiece 7c conveying.

[0112] According to some embodiments of the present application, as shown in Figure 6 、 Figure 10 and Figure 11 , the gripping device 32c includes a mechanical arm 4c and a gripper 5c, one end of the mechanical arm 4c is connected to the first moving base 31c, and the gripper 5c is provided at the other end of the mechanical arm 4c. The gripper 5c includes a mounting plate 51c, a gripper driving mechanism 52c, and at least one pair of clamping blocks 53c, and the gripper driving mechanism 52c is provided on the mounting plate 51c. The mechanical arm 4c can adopt a multi-joint mechanical arm, such as a 6-joint. That is, the gripper 5c is connected to the mechanical arm 4c through the mounting plate 51c, which can better reduce the connection difficulty of the gripper 5c and the mechanical arm 4c, facilitate the assembly difficulty of the gripping device 32c, and reduce the maintenance difficulty of the gripping device 32c in the later period. In addition, the position and angle of the gripper 5c can be flexibly adjusted through the mechanical arm 4c, so that the gripper 5c can accurately move to the position of grasping or releasing the workpiece 7c, thereby achieving accurate transfer of the workpiece 7c. Among them, the clamping block 53c can be provided with one pair, two pairs or three pairs, etc., which can be flexibly set according to the size and transfer requirements of the workpiece 7c, which is not specifically limited here.

[0113] The clamping jaw driving mechanism 52c is configured to drive the pair of clamping blocks 53c to move away from or close to each other to clamp or release the workpiece 7c. Each clamping block 53c is provided with a clamping mechanism 54c configured to clamp the workpiece 7c. Here, the clamping block 53c is taken as an example of a pair. When the grabbing device 32c grabs the workpiece 7c, the clamping jaw driving mechanism 52c can drive the two clamping blocks 53c to move away from each other, so that the two clamping blocks 53c can be located on the opposite sides of the workpiece 7c, for example, the width direction. The clamping jaw driving mechanism 52c drives the two clamping blocks 53c to move close to each other until the workpiece 7c is supported on the clamping mechanism 54c, and the clamping mechanism 54c further clamps the workpiece 7c, thereby limiting the freedom of the workpiece 7c, which is beneficial to ensure the stable transfer of the workpiece 7c. When the grabbing device 32c releases the workpiece 7c, the clamping mechanism 54c can first release the clamping action on the workpiece 7c, and the clamping jaw driving mechanism 52c drives the two clamping blocks 53c to move away from each other, thereby releasing the clamping action of the two clamping blocks 53c on the workpiece 7c, so as to place the workpiece 7c at a specified release position.

[0114] Further, the mounting plate 51c is further provided with a CCD camera 33c configured to scan the workpiece 7c to obtain workpiece 7c information. The workpiece 7c is provided with a two-dimensional code storing the workpiece 7c information, which can include information to be processed, such as the number and position of holes in the workpiece 7c. Therefore, during the transfer of the workpiece 7c, the CCD camera 33c can timely obtain the workpiece 7c information and upload it to the processing equipment 200c, so that the processing equipment 200c can perform specified processing operations on the workpiece 7c according to the workpiece 7c information, thereby better saving the difficulty of entering the workpiece 7c information, and the entering speed is fast, which is beneficial to improve the processing efficiency of the processing equipment 200c. In addition, it can better save the labor input of information input, and can better avoid the risk of manual input information error, which is beneficial to improve the reliability of workpiece 7c processing. Moreover, during the feeding process of the workpiece 7c to be processed, the CCD camera 33c obtains the workpiece 7c information and judges whether the information of the transferred workpiece 7c is consistent with the workpiece 7c information in the feeding request of the processing equipment 200c, that is, the grabbing device 32c only transfers the workpiece 7c in the feeding request of the processing equipment 200c, so as to ensure the accuracy of feeding.

[0115] In addition, the grabbing device 32c further comprises a support base and a temporary storage platform arranged on the support base. During the machining of the workpiece 7c by the machining equipment 200c, machining records and the like can be recorded in the workpiece 7c information. Therefore, when the workpiece 7c is machined with errors, the CCD camera 33c can obtain error information when the workpiece 7c is transferred by the grabbing device 32c. The grabbing device 32c can temporarily place the workpiece 7c with error information on the temporary storage platform, so as to distinguish the workpieces 7c machined correctly and with errors, that is, the grabbing device 32c can better reject the workpieces 7c machined with errors. In addition, when the position and placement direction of the workpiece 7c grabbed by the grabbing device 32c is opposite to the preset direction, the workpiece 7c can be first grabbed and transferred to the temporary storage platform, and then the gripper 5c is clamped and grabbed from below the workpiece 7c by the mechanical arm 4c. The mechanical arm 4c continues to drive the gripper 5c and the workpiece 7c to flip, so that the workpiece 7c is placed on the feeding and discharging platform 2c in the preset direction. Alternatively, the temporary storage platform comprises a vertical rod and a cross beam arranged on the support base. The vertical rod is arranged on the support base, and the cross beam is arranged on the vertical rod and away from the support base. The cross beam is used for supporting the workpiece 7c. In some embodiments of the present application, the feeding and discharging platform 2c further comprises a placing rack arranged above the conveyor table 21c. When the grabbing device 32c grabs the workpiece 7c containing error information, the workpiece 7c machined with errors can be placed on the placing rack for temporary storage.

[0116] Alternatively, the gripper driving mechanism 52c is a gas cylinder, an electric cylinder, a belt driving mechanism or a lead screw feeding mechanism. In a specific example, the gripper driving mechanism 52c is a gas cylinder. That is, the two opposite clamping blocks 53c are driven by the gas cylinder to move close to or away from each other. The distance between the two clamping blocks 53c can be accurately controlled, so as to ensure that the two clamping blocks 53c can stably clamp the workpiece 7c while avoiding that the clamping force of the two clamping blocks 53c is too large to damage the workpiece 7c.

[0117] Alternatively, the clamping mechanism 54c comprises a first pressing cylinder 55c and a second pressing cylinder 56c arranged on the clamping block 53c. The first pressing cylinder 55c comprises a first cylinder 551c and a first pressing block 552c. The first cylinder 551c is arranged on the clamping block 53c and can drive the first pressing block 552c to extend and retract. The second pressing cylinder 56c comprises a second cylinder 561c and a second pressing block 562c. The second cylinder 561c is arranged on the clamping block 53c and can drive the second pressing block 562c to extend and retract and rotate. The workpiece 7c is adapted to be clamped in a clamping space 57c defined by the first pressing block 552c and the second pressing block 562c. The second pressing block 562c is rotatable between a clamping position and a release position. In the clamping position, the second pressing block 562c is opposite to the first pressing block 552c. In the release position, the second pressing block 562c is staggered with the first pressing block 552c and located on the side of the clamping block 53c away from the clamping space 57c.

[0118] That is, in the releasing position, the second pressing block 562c is staggered with the first pressing block 552c, i.e. the clamping space 57c is open on the side opposite to the first pressing block 552c, so that at least part of the workpiece 7c can be put into the clamping space 57c through the open position, the second cylinder 561c drives the second pressing block 562c to rotate to the clamping position, the opposite side walls of the first pressing block 552c and the second pressing block 562c are located on the opposite sides (such as the thickness direction) of the workpiece 7c, the first cylinder 551c drives the first pressing block 552c to move, the second cylinder 561c drives the second pressing block 562c to move, so that the first pressing block 552c and the second pressing block 562c approach each other, until the opposite side walls of the first pressing block 552c and the second pressing block 562c respectively abut the two sides in the thickness direction of the workpiece 7c, to limit the activity freedom of the workpiece 7c in the thickness direction; when releasing the workpiece 7c, the first cylinder 551c drives the first pressing block 552c to move, the second cylinder 561c drives the second pressing block 562c to move, so that the first pressing block 552c and the second pressing block 562c move away from each other, the second cylinder 561c drives the second pressing block 562c to rotate to the other side of the clamping block 53c, and the workpiece 7c can be released from the side of the clamping space 57c opposite to the first pressing block 552c.

[0119] In one specific example, as shown in Figure 11 the first pressing cylinder 55c is arranged on the inner side of the clamping block 53c, and the second pressing cylinder 56c is arranged on the outer side of the clamping block 53c, when the second pressing block 562c is in the clamping position, part of the second pressing block 562c extends out of the inner side of the clamping block 53c, the part of the second pressing block 562c extending out of the clamping block 53c is arranged opposite to the first pressing block 552c, and the second pressing block 562c is located on the side of the first pressing block 552c away from the mounting plate 51c, the first pressing block 552c and the second pressing block 562c are adapted to clamp on the two sides in the thickness direction of the workpiece 7c, and the two opposite clamping blocks 53c are adapted to clamp on the two sides in the length direction or the width direction of the workpiece 7c, so that the clamping jaw 5c can at least clamp and fix the workpiece 7c from two directions, to ensure the stable transfer of the workpiece 7c.

[0120] In another specific example, the clamping mechanism 54c includes the first pressing cylinder 55c arranged on the clamping block 53c and the support body arranged on the clamping block 53c, and the first pressing cylinder 55c and the support body are arranged opposite to each other in the up-down direction. Thus, the first pressing block 552c can be driven by the first cylinder 551c of the first pressing cylinder 55c to move towards or away from the support body in the up-down direction, so as to clamp or release the workpiece 7c in the up-down direction, and the structure is simple and conducive to saving the production cost of the clamping mechanism 54.

[0121] The automatic machining production line 1000c according to an embodiment of the present application will be described below with reference to the accompanying drawings.

[0122] As shown in Figure 1 andFigure 2 As shown, the automatic processing production line 1000c according to an embodiment of the present invention includes: processing equipment 200c, automatic loading and unloading system 100c, and transport vehicle 300c.

[0123] Among them, such as Figure 12 As shown, the processing equipment 200c is used to process the workpiece 7c.

[0124] Among them, such as Figure 13 and Figure 14 As shown, the transport cart 300c is adapted to transfer workpieces 7c between the buffer platform 1c of the automatic loading and unloading system 100c and the processing equipment 200c. The transport cart 300c has a receiving and dispatching port 301c. The receiving and dispatching port 301c of the transport cart 300c is adapted to dock with the buffer platform 1c to receive workpieces 7c to be processed and / or transfer processed workpieces 7c to the buffer platform 1c. The receiving and dispatching port 301c of the transport cart 300c is adapted to dock with the inlet and outlet port 210c of the processing equipment 200c to transfer workpieces 7c to be delivered to the processing equipment 200c and / or receive processed workpieces 7c output by the processing equipment 200c. Specifically, the workpiece 7c to be processed is transferred and transported to the buffer platform 1c by the material transport trolley 6c, the transfer trolley 3c and the loading and unloading platform 2c. When the transport trolley 300c docks with the buffer platform 1c, the buffer platform 1c can transport the workpiece 7c to be processed to the transport trolley 300c. The transport trolley 300c receives the workpiece 7c to be processed from the buffer platform 1c and temporarily stores the workpiece 7c to be processed in the transport trolley 300c. The transport cart 300c can transport and transfer the temporarily stored workpieces 7c to the processing equipment 200c. The transport cart 300c moves to the position where it docks with the processing equipment 200c and docks with the processing equipment 200c. At this time, the receiving and dispatching port 301c of the transport cart 300c is opposite to the inlet and outlet port 210c of the processing equipment 200c. The transport cart 300c can transport and transfer the temporarily stored workpieces 7c to the processing equipment 200c for processing, thereby realizing the automatic feeding of the workpieces 7c to be processed.

[0125] When the machining device 200c has finished machining the workpiece 7c, the transport trolley 300c can move to a position in abutment with the machining device 200c and abut with the machining device 200c, the machining device 200c transfers the machined workpiece 7c to the transport trolley 300c, after the transport trolley 300c receives the machined workpiece 7c, the transport trolley 300c moves to a position in abutment with the buffer platform 1c and abuts with the buffer platform 1c, the transport trolley 300c can transfer the temporarily stored machined workpiece 7c to the buffer platform 1c through the receiving and feeding port 301c, and the machined workpiece 7c is concentrated and transported to a designated position through the feeding and discharging platform 2c, the transfer trolley 3c and the material trolley 6c, so that the automatic discharging of the machined workpiece 7c can be realized.

[0127] According to some embodiments of the application, as shown in Figure 2 and Figure 14 The machining device 200c is provided with multiple machining devices 200c, and the multiple machining devices 200c are arranged in one or more rows along a straight line, for example, the automatic machining production line 1000c can include multiple machining devices 200c arranged in one row along a straight line, the automatic machining production line 1000c can also include two rows of multiple machining devices 200c arranged along a straight line, the automatic machining production line 1000c can also include three rows of multiple machining devices 200c arranged along a straight line, which is not specifically limited here.

That is, the automatic feeding and discharging system 100c and all the processing devices 200c in one row of processing devices 200c are arranged in a straight line, and the walking path 600c can accurately guide the transport trolley 300c to move to the position close to the in-out port 210c of each processing device 200c, that is, the docking position of the processing device 200c, so as to realize accurate navigation of the transport trolley 300c, and can reduce the docking difficulty of the transport trolley 300c and the processing device 200c. In addition, when the transport trolley 300c transports the workpiece 7c to be processed to one row of processing devices 200c or receives the processed workpiece 7c from one row of processing devices 200c, the transport trolley 300c can walk in a straight line, so that the walking path 600c is simple, and the control difficulty of the transport trolley 300c is reduced.

[0129] In some embodiments of the present application, the plurality of processing devices 200c are arranged in two rows in a straight line, the in-out ports 210c of the two rows of processing devices 200c are oppositely arranged, the walking path 600c is approximately in the shape of "U" when the transport trolley 300c is provided with the receiving and discharging port 301c on one side only, and the automatic feeding and discharging system 100c is located on one side of the arrangement direction of one row of processing devices 200c. When the transport trolley 300c transfers the workpiece 7c to be processed to the plurality of processing devices 200c, the transport trolley 300c starts from the starting point of the walking path 600c (that is, the position of the automatic feeding and discharging system 100c), walks along the corresponding walking path 600c of one row of processing devices 200c, and transfers the workpiece 7c to be processed to the processing device 200c by docking with the plurality of processing devices 200c respectively, turns at the end of the current row of processing devices 200c (that is, the side of the current row of processing devices 200c away from the automatic feeding and discharging system 100c), so that the receiving and discharging port 301c faces the other row of processing devices 200c, and continues to walk in a straight line to sequentially transfer the workpiece 7c to be processed to the plurality of processing devices 200c in the other row.

[0130] Further, as shown in FIG. 6, the automatic feeding and discharging system 100c is provided with a plurality of receiving and discharging ports 301c, and the plurality of receiving and discharging ports 301c are arranged in a straight line. Figure 14 and Figure 15As shown, the bottom surface of the transport trolley 300c is provided with a positioning sensor 302c, which is used to identify the walking path 600c, the walking path 600c includes a positioning code set 610c provided on the ground, the positioning code set 610c includes a plurality of walking positioning codes 611c, a first docking positioning code 622c and a second docking positioning code 623c. For example, the walking positioning code 611c can be a two-dimensional code printed or pasted on the ground. During the walking process of the transport trolley 300c, the walking positioning code 611c is collected by the positioning sensor 302c of the transport trolley 300c, and the walking direction of the transport trolley 300c is adjusted in real time, so that the transport trolley 300c can walk stably along the walking path 600c.

[0131] In addition, the ground adjacent to one side of the buffer platform 1c is provided with the first docking positioning code 622c. When the positioning sensor 302c identifies the first docking positioning code 622c, the transport trolley 300c stops walking to dock with the buffer platform 1c. The first docking positioning code 622c can be a two-dimensional code printed or pasted on the ground. Specifically, during the walking process of the transport trolley 300c along the walking path 600c, when the positioning sensor 302c of the transport trolley 300c identifies the first docking positioning code 622c, it indicates that the transport trolley 300c has moved to the side of the buffer platform 1c for docking. The transport trolley 300c stops walking to dock with the buffer platform 1c. The first docking positioning code 622c can be used to accurately control the transport trolley 300c to stop at the side of the buffer platform 1c for docking, thereby facilitating the docking with the buffer platform 1c.

[0132] In addition, the ground adjacent to one side of the buffer platform 1c is provided with the first docking positioning code 622c. When the positioning sensor 302c identifies the first docking positioning code 622c, the transport trolley 300c stops walking to dock with the buffer platform 1c. The first docking positioning code 622c can be a two-dimensional code printed or pasted on the ground. Specifically, during the walking process of the transport trolley 300c along the walking path 600c, when the positioning sensor 302c of the transport trolley 300c identifies the first docking positioning code 622c, it indicates that the transport trolley 300c has moved to the side of the buffer platform 1c for docking. The transport trolley 300c stops walking to dock with the buffer platform 1c. The first docking positioning code 622c can be used to accurately control the transport trolley 300c to stop at the side of the buffer platform 1c for docking, thereby facilitating the docking with the buffer platform 1c.

[0133] Further, as shown in FIG. 6, the buffer platform 1c is provided with a plurality of buffer positioning codes 612c, which are arranged in a plurality of rows and columns on the buffer platform 1c. The buffer positioning codes 612c can be two-dimensional codes printed or pasted on the buffer platform 1c. During the walking process of the transport trolley 300c along the walking path 600c, the buffer positioning codes 612c are collected by the positioning sensor 302c of the transport trolley 300c, and the walking direction of the transport trolley 300c is adjusted in real time, so that the transport trolley 300c can walk stably along the walking path 600c. Figure 12 , Figure 13 and Figure 16As shown, the side of the transport trolley 300c adjacent to the material receiving and delivery port 301c is provided with a distance measuring sensor 303c and a photoelectric sensor 304c, the side of the buffer platform 1c adapted to be docked with the transport trolley 300c is provided with a first distance measuring reflector and a first positioning reflector strip (not shown in the figure), and the side of the processing equipment 200c adjacent to the material receiving and delivery port 210c is provided with a second distance measuring reflector 220c and a second positioning reflector strip 230c.

[0134] In the process of the transport trolley 300c moving along the walking path 600c, when the positioning sensor 302c of the transport trolley 300c recognizes the first docking positioning code 622c, it means that the transport trolley 300c has moved to the side to be docked with the buffer platform 1c, and the transport trolley 300c stops at the position of the first docking positioning code 622c. When the distance measuring sensor 303c on the transport trolley 300c detects that the distance between the first distance measuring reflector on the buffer platform 1c reaches a first preset value, and the detection light emitted by the photoelectric sensor 304c is reflected by the first positioning reflector strip and then reflected back to the photoelectric sensor 304c, it means that the transport trolley 300c is docked with the buffer platform 1c in place. If the distance measuring sensor 303c on the transport trolley 300c detects that the distance between the first distance measuring reflector on the buffer platform 1c is not within the first preset value range or the photoelectric sensor 304c does not receive the detection light reflected by the first positioning reflector strip, it means that the transport trolley 300c does not accurately stop at the position to be docked with the buffer platform 1c. The transport trolley 300c can be controlled to automatically adjust the position so that the distance measuring sensor 303c on the transport trolley 300c detects that the distance between the first distance measuring reflector on the buffer platform 1c reaches the first preset value, and the detection light emitted by the photoelectric sensor 304c is reflected by the first positioning reflector strip and then reflected back to the photoelectric sensor 304c.

[0135] In the process of the transport trolley 300c moving along the walking path 600c, when the positioning sensor 302c of the transport trolley 300c recognizes the second docking positioning code 623c, it means that the transport trolley 300c moves to the side of the in-out port 210c of the processing equipment 200c, and the transport trolley 300c stops at the position of the second docking positioning code 623c. When the distance between the ranging sensor 303c on the transport trolley 300c and the second ranging reflector 220c on the processing equipment 200c reaches the second preset value, and the detection light emitted by the photoelectric sensor 304c is reflected by the second positioning reflector 230c and returned to the photoelectric sensor 304c, it means that the transport trolley 300c is docked with the processing equipment 200c. If the distance between the ranging sensor 303c on the transport trolley 300c and the second ranging reflector 220c on the processing equipment 200c is not within the second preset value range, or the photoelectric sensor 304c does not receive the detection light reflected by the second positioning reflector 230c, it means that the transport trolley 300c is not accurately stopped at the position for docking with the processing equipment 200c. The transport trolley 300c can be controlled to automatically adjust the position so that the distance between the ranging sensor 303c on the transport trolley 300c and the second ranging reflector 220c on the processing equipment 200c reaches the second preset value, and the detection light emitted by the photoelectric sensor 304c can be reflected by the second positioning reflector 230c and returned to the photoelectric sensor 304c.

The storage device 306c is arranged on the walking device 305c. The walking device 305c can drive the transport trolley 300c to move to a position for docking with the buffer platform 1c, and transport the processed workpiece 7c to the buffer platform 1c or receive the workpiece 7c to be processed output by the buffer platform 1c through the docking with the buffer platform 1c.

Any layer of the storage bin 331c can be located at the in-out position through the lifting of the storage mechanism 330c. The in-out position refers to that the workpiece 7c in the storage bin 331c located at the in-out position can be transferred out of the storage bin 331c through the receiving and feeding port 301c, or the workpiece 7c can be moved into the storage bin 331c located at the in-out position through the receiving and feeding port 301c.

[0138] That is, the storage device 306c includes multiple storage stations 332c arranged along the horizontal direction and the up-down direction, and multiple workpieces 7c can be transported into the multiple storage stations 332c for storage, so as to better improve the storage capacity of the transport trolley 300c, and the workpieces 7c are transferred through the storage stations 332c, so that the transport trolley 300c can automatically transport the workpieces. In addition, the second lifting mechanism 340c can flexibly adjust the height position of the multiple layers of storage bins 331c, for example, the multiple layers of storage bins 331c can be raised, or the height of the multiple layers of storage bins 331c can be lowered, so that one of the storage bins 331c is located at the feeding and discharging position, for example, the storage bin 331c at the feeding and discharging position can be aligned with the receiving and feeding port 301c, so that the workpiece 7c can be transported through the receiving and feeding port 301c to the multiple storage stations 332c of the storage bin 331c aligned with the receiving and feeding port 301c, or the workpiece 7c on the multiple storage stations 332c of the storage bin 331c aligned with the receiving and feeding port 301c can be output through the receiving and feeding port 301c, which facilitates the transportation of the workpiece 7c on the multiple layers of storage bins 331c.

[0139] The number and position of the receiving and feeding port 301c can be set according to the layout mode of the processing equipment 200c. In one specific embodiment, as shown in Figure 14 The automatic processing production line 1000c includes multiple processing equipment 200c, and the buffer platform 1c and the multiple processing equipment 200c are arranged in a straight line, that is, the buffer platform 1c and the multiple processing equipment 200c are located on the same side of the transport trolley 300c, wherein the feeding and discharging port 210c of the processing equipment 200c and the docking position of the transport trolley 300c and the buffer platform 1c are located on the same side, the transport trolley 300c moves on the side of the processing equipment 200c provided with the feeding and discharging port 210c, and the shell 380c is provided with the receiving and feeding port 301c on the side close to the automatic feeding and discharging system 100c and the processing equipment 200c, so that the transport trolley 300c can walk in a straight line to transfer the workpiece 7c between the buffer platform 1c and the processing equipment 200c.

[0140] In another specific example, as shown in Figure 2As shown, the automatic machining production line 1000c includes two rows of linearly arranged machining devices 200c, the buffer platform 1c is located on one side of the arrangement direction of one row of machining devices 200c, the inlets and outlets 210c of the two rows of machining devices 200c are oppositely arranged, the transport trolley 300c is movable between the two rows of machining devices 200c, the docking position of the transport trolley 300c and the buffer platform 1c is located on the side of the buffer platform 1c facing the other row of machining devices 200c, and the two sides of the shell 380c are provided with the receiving and feeding ports 301c, so that the transport trolley 300c can transport the workpieces 7c to be machined to the two rows of machining devices 200c or receive the machined workpieces 7c from the two rows of machining devices 200c when moving linearly between the two rows of machining devices 200c, that is, the transport trolley 300c does not need to turn around during the transfer of the workpieces 7c, so that the walking route of the transport trolley 300c can be simplified, and the control difficulty is low.

[0141] Optionally, the number of the buffer stations 12c of each layer of the buffer storage bins 11c is the same as and one-to-one corresponds to the number of the storage stations 332c of each layer of the storage bins 331c. Specifically, when the transport trolley 300c is docked with the buffer platform 1c, the workpieces 7c to be machined on the buffer stations 12c of one layer of the buffer storage bins 11c can be simultaneously transported to the storage stations 332c of one layer of the storage bins 331c through the receiving and feeding ports 301c for storage, so as to realize the rapid batch output of the workpieces 7c buffered by one layer of the buffer storage bins 11c; or the machined workpieces 7c on the storage stations 332c of one layer of the storage bins 331c can be simultaneously transported to the buffer stations 12c of one layer of the buffer storage bins 11c through the receiving and feeding ports 301c for buffering, so as to realize the rapid batch output of the workpieces 7c stored by one layer of the storage bins 331c, and facilitate to improve the transfer efficiency of the workpieces 7c between the buffer platform 1c and the transport trolley 300c.

[0142] Optionally, as shown in FIG. 9, the buffer platform 1c includes a plurality of buffer storage bins 11c arranged in a plurality of layers, and each buffer storage bin 11c includes a plurality of buffer stations 12c arranged in a row. Figure 20As shown, the processing equipment 200c has a plurality of processing stations 250c arranged in a horizontal direction, and the number of the processing stations 250c is the same as and corresponds to the number of the storage stations 332c of each layer of the storage bins 331c. That is, when the processing equipment 200c requests feeding, the transport trolley 300c is docked with the processing equipment 200c, and the transport trolley 300c can simultaneously transport the workpieces 7c to be processed on the plurality of storage stations 332c of the layer of the storage bins 331c to the plurality of processing stations 250c of the processing equipment 200c through the material receiving and feeding port 301c and the in-out material port 210c of the processing equipment 200c, so that the rapid feeding of the workpieces 7c to be processed can be realized; after the workpieces 7c are processed, the transport trolley 300c is docked with the processing equipment 200c, and the processing equipment 200c can simultaneously transport the processed workpieces 7c on the plurality of processing stations 250c to the plurality of storage stations 332c of the layer of the storage bins 331c through the in-out material port 210c and the material receiving and feeding port 301c of the transport trolley 300c, so that the rapid feeding of the processed workpieces 7c can be realized. In addition, the processing equipment 200c can simultaneously process a plurality of workpieces 7c on the plurality of processing stations 250c, which is beneficial to improving the processing efficiency of the processing equipment 200c.

[0143] Optionally, as shown, Figures 17-19 The storage device body 310c includes an in-out material mechanism 350c, which includes a driving unit 360c and a plurality of in-out material transmission units 370c arranged in a horizontal direction. The driving unit 360c is connected to all the in-out material transmission units 370c to drive all the in-out material transmission units 370c to synchronously transmit the workpieces 7c. The number of the in-out material transmission units 370c is the same as and corresponds to the number of the storage stations 332c of each layer of the storage bins 331c. All the storage stations 332c of the storage bin 331c located at the in-out material position are detachably connected to the corresponding in-out material transmission unit 370c. When the storage station 332c of the storage bin 331c located at the in-out material position is connected to the corresponding in-out material transmission unit 370c, the in-out material mechanism 350c can drive all the storage stations 332c of the storage bin 331c located at the in-out material position to synchronously transmit the workpieces 7c.

[0144] Specifically, when the transport trolley 300c is conveying the workpieces 7c, the second lifting mechanism 340c drives the second support frame 320c to lift so that one layer of the storage bins 331c is located at the feeding and discharging position, and controls the plurality of feeding and discharging transmission units 370c of the feeding and discharging mechanism 350c to be in transmission connection with the plurality of storage stations 332c on the current storage bin 331c, and the driving units 360c drive all the feeding and discharging transmission units 370c to synchronously convey the workpieces 7c on all the storage stations 332c. After the workpieces 7c on the storage bin 331c located at the feeding and discharging position are conveyed, the plurality of feeding and discharging transmission units 370c of the feeding and discharging mechanism 350c are separated from the plurality of storage stations 332c on the storage bin 331c, and the second lifting mechanism 340c drives the second support frame 320c to lift so as to drive another layer of the storage bins 331c to the feeding and discharging position to convey the workpieces 7c. In this way, the interference risk caused by the transmission connection between the storage stations 332c and the feeding and discharging transmission units 370c during the lifting of the second support frame 320c can be avoided, and the reliability of the storage device 306c can be improved.

[0145] Optionally, the storage device body 310c comprises a driving assembly for driving the storage stations 332c to convey the workpieces 7c, and the driving assembly comprises a plurality of driving mechanisms, wherein the number of the driving mechanisms is the same as and one-to-one corresponds to the number of the storage bins 331c, i.e., each driving mechanism can drive all the storage stations 332c on the corresponding storage bin 331c to convey the workpieces, so as to improve the conveying efficiency of the storage device body 310c for the workpieces 7c. Alternatively, the number of the driving mechanisms is the same as and one-to-one corresponds to the number of the storage stations 332c, i.e., each driving mechanism can drive the corresponding storage station 332c to convey the workpieces, so that the storage stations 332c can output a specified number of workpieces 7c according to the demand of the machining equipment 200c, and the interference between the plurality of storage stations 332c can be avoided, and the reliability of the transport trolley 300c can be improved.

[0146] Further, as Figures 21-22As shown, the storage station 332c includes a storage base 333c and a conveying assembly 334c arranged on the storage base 333c and configured to convey the workpieces 7c, each of the in-out conveying driving units 370c includes a mounting base 371c and a clutch assembly 372c arranged on the mounting base 371c, the clutch assembly 372c includes a driver 373c and a transmission member 374c connected with the driver 373c to drive the transmission member 374c to move between an engagement position and a disengagement position, all the transmission members 374c are connected with the driving unit 360c, when the transmission member 374c is located at the engagement position, the transmission member 374c is drivingly connected with the corresponding conveying assembly 334c, the driving unit 360c drives the corresponding conveying assembly 334c to convey the workpieces 7c through the transmission member 374c, when the transmission member 374c is located at the disengagement position, the transmission member 374c is disengaged from the conveying assembly 334c. That is, the clutch assembly 372c is one-to-one corresponding to the plurality of storage stations 332c on the one layer of the storage bin 331c at the in-out position, and the in-out conveying driving unit 370c can be drivingly connected or disengaged from the corresponding conveying assembly 334c through the clutch assembly 372c.

[0147] Specifically, when the transport trolley 300c conveys the workpieces 7c, the drivers 373c of all the clutch assemblies 372c drive the corresponding transmission members 374c to remain at the disengagement position, the second lifting mechanism 340c drives the second support frame 320c to lift so that one layer of the storage bin 331c is located at the in-out position, then the drivers 373c of all the clutch assemblies 372c drive the corresponding transmission members 374c to the engagement position, the plurality of in-out conveying driving units 370c are one-to-one drivingly connected with the plurality of conveying assemblies 334c of the current storage bin 331c, and the driving unit 360c drives all the transmission members 374c to rotate to drive all the conveying assemblies 334c on the current storage bin 331c to convey the workpieces 7c. After the workpieces 7c on the current storage bin 331c are conveyed, the drivers 373c of all the clutch assemblies 372c drive the corresponding transmission members 374c to the disengagement position, for example, the transmission members 374c are completely spaced apart from the conveying assemblies 334c at this time, that is, the plurality of in-out conveying driving units 370c are disengaged from the plurality of conveying assemblies 334c, so that the interference risk between the conveying assemblies 334c and the in-out conveying driving units 370c caused by the lifting of the second support frame 320c can be avoided, and the reliability of the storage device 306c is improved.

[0148] Further, the transmission assembly comprises at least one conveying mechanism 335c, the conveying mechanism 335c comprises a docking gear 336c, the transmission member 374c comprises a transmission bracket 375c and a gear transmission mechanism 376c, the gear transmission mechanism 376c is arranged on the transmission bracket 375c, all the gear transmission mechanisms 376c are drivingly connected with the driving unit 360c, the driver 373c is connected with the corresponding transmission bracket 375c to drive the transmission bracket 375c to move between the docking position and the separated position, when the transmission bracket 375c is located at the docking position, the gear transmission mechanism 376c is engaged with the corresponding docking gear 336c, when the transmission bracket 375c is located at the separated position, the gear transmission mechanism 376c is separated from the docking gear 336c. That is, through the cooperation of the gear transmission mechanism 376c and the docking gear 336c, the conveying mechanism 335c and the in-out conveying transmission unit 370c are drivingly connected or separated, so that the transmission structure is simple.

[0149] Specifically, when the transport trolley 300c conveys the workpieces 7c, all the drivers 373c drive the transmission members 374c to keep at the separated position, the docking gears 336c are completely spaced apart from the gear transmission mechanisms 376c, the second lifting mechanism 340c drives the second support frame 320c to lift, so that one of the storage bins 331c is located at the in-out position, all the drivers 373c of the clutch assemblies 372c drive the corresponding transmission brackets 375c to the docking position, a plurality of gear transmission mechanisms 376c are engaged with a plurality of docking gears 336c of the current storage bin 331c one by one, and the driving unit 360c drives all the gear transmission mechanisms 376c to rotate to drive all the conveying mechanisms 335c on the current storage bin 331c to convey the workpieces 7c. After the conveying of the workpieces 7c on the current storage bin 331c is completed, all the drivers 373c of the clutch assemblies 372c drive the corresponding transmission brackets 375c to the separated position, and all the gear transmission mechanisms 376c are separated from the corresponding docking gears 336c, that is, a plurality of in-out conveying transmission units 370c are separated from a plurality of conveying assemblies 334c, so that the interference risk caused by the engagement of the docking gears 336c and the gear transmission mechanisms 376c during the lifting of the second support frame 320c can be better avoided, and the reliability of the storage device 306c is improved.

[0150] Further, each of the in-out material transmission units 370c comprises a transmission shaft 377c penetrating through a corresponding transmission support 375c, the transmission support 375c being rotatable relative to the transmission shaft 377c, the driver 373c being connected with a push plate 378c of the corresponding transmission support 375c, the driver 373c driving the transmission support 375c to rotate between the abutting position and the separated position through the push plate 378c, each of the gear transmission mechanisms 376c being coaxially arranged on the corresponding transmission shaft 377c, the driving unit 360c being connected with one of the transmission shafts 377c to drive all the transmission shafts 377c to rotate synchronously. That is, the transmission shafts 377c of the plurality of in-out material transmission units 370c are all transmissionally connected, the driver 373c being capable of driving the push plate 378c to extend or retract, so as to drive the transmission support 375c to rotate relative to the transmission shaft 377c through the push plate 378c. For example, the push plate 378c is connected with one end of the transmission support 375c away from the transmission shaft 377c, so that the push plate 378c can drive the one end of the transmission support 375c away from the transmission shaft 377c to rotate relative to the transmission shaft 377c, so that the one end of the transmission support 375c away from the transmission shaft 377c can be close to or away from the abutting gear 336c, so that the gear transmission mechanism 376c on the transmission support 375c can be engaged with or separated from the abutting gear 336c. Secondly, the abutting position and the separated position can be two limit positions in the process of the transmission support 375c rotating relative to the transmission shaft 377c, so as to accurately control the position of the transmission support 375c. For example, when the transmission support 375c is in the abutting position, the gear transmission mechanism 376c can be fully engaged with the abutting gear 336c, so as to prevent the transmission support 375c from moving excessively to cause the gear transmission mechanism 376c and the abutting gear 336c to be excessively pressed against each other.

[0151] In some embodiments of the present application, the mounting bottom plate 371c is arranged on the second support frame 320c, the in-out material mechanism 350c is located on one side of the storage mechanism 330c adjacent to the material receiving and sending opening 301c, each of the in-out material transmission units 370c further comprises a matching transmission assembly 379c arranged on the mounting bottom plate 371c, the matching transmission assembly 379c being used for supporting and transmitting the workpiece 7c, the workpiece 7c being transferable between the matching transmission assembly 379c and the corresponding conveying assembly 334c when the transmission member 374c is in the abutting position, the matching transmission assembly 379c penetrating through the corresponding transmission shaft 377c, the driving unit 360c driving the matching transmission assembly 379c to transmit the workpiece 7c through the transmission shaft 377c, so that the matching transmission assembly 379c can be connected between the plurality of conveying assemblies 334c located in the in-out material position and the material receiving and sending opening 301c, avoiding the workpiece 7c from being unable to accurately pass through the material receiving and sending opening 301c, so as to realize the stable conveying of the workpiece 7c. Wherein, the matching transmission assembly 379c and the conveying assembly 334c can be the belt conveying mechanism 10a.

[0152] In some embodiments of the present application, the number of layers of the buffer bins 11c is the same as the number of layers of the storage bins 331c, and specifically, the buffer mechanism 14c buffers the workpieces 7c to be processed, and the transport trolley 300c stores the processed workpieces 7c, wherein one layer of the buffer bins 11c in the buffer platform 1c is empty and / or one layer of the storage bins 331c in the storage mechanism 330c is empty. For example, when one layer of the buffer bins 11c is empty, the storage mechanism 330c can first transport the processed workpieces 7c on one layer of the storage bins 331c to the empty buffer bin 11c, and then control the buffer mechanism 14c to ascend and descend so that the buffer bin 11c buffering the workpieces 7c to be processed is aligned with the empty storage bin 331c, and the workpieces 7c to be processed are transported to the empty storage bin 331c. The above process is repeated until all the processed workpieces 7c in the storage mechanism 330c are exchanged with all the workpieces 7c to be processed in the buffer mechanism 14c. The structure of the buffer platform 1c can be the same as that of the storage device 306c.

[0153] According to some embodiments of the present application, as shown in Figure 20 、 Figure 23 and Figure 24 , the processing equipment 200c comprises a workbench 240c, and the workbench 240c is provided with a tool placement area 241c. The automatic processing production line 1000c further comprises a tool changing buffer platform 400c, and the tool changing buffer platform 400c comprises a third mobile base 410c, a placement table 420c and a grabbing mechanism 430c. The third mobile base 410c is movable on the ground, and the placement table 420c is arranged on the third mobile base 410c. The placement table 420c has a first storage area 421c and a second storage area 423c. The first storage area 421c is used for storing tools to be used, and the second storage area 423c is used for storing used tools.

[0154] That is, the third mobile base 410c can drive the tool changing buffer platform 400c to move on the ground, so as to improve the moving flexibility and movable range of the tool changing buffer platform 400c. In one specific example, the processing equipment 200c is provided with a plurality of processing equipment 200c, which are distributed in a processing site. Therefore, the third mobile base 410c can drive the tool changing buffer platform 400c to the positions of the plurality of processing equipment 200c, so that the tool changing buffer platform 400c can cooperate with the plurality of processing equipment 200c to perform tool changing work, so that the working range of the tool changing buffer platform 400c is wide, and the number of the tool changing buffer platforms 400c can be reduced, thereby reducing the purchase cost of the tool changing buffer platforms 400c.

[0155] The to-be-used tool is a tool meeting the machining requirements, and the used tool is a tool that does not meet the machining requirements due to wear and the like. In this way, by placing the to-be-used tool and the used tool in different areas, the risk of tool change errors caused by the to-be-used tool and the used tool being mixed can be avoided, and the reliability of the tool change buffer platform 400c can be improved.

[0156] Further, the grabbing mechanism 430c is arranged on the placement table 420c, and is used to transfer the tool in the first storage area 421c to the tool placement area 241c and transfer the used tool in the tool placement area 241c to the second storage area 423c. That is, the grabbing mechanism 430c can transfer the to-be-used tool in the first storage area 421c to the machining device 200c, so that the machining device 200c can timely replace the used tool with the to-be-used tool, to ensure that the machining device 200c can continuously and effectively perform machining operations. After the machining device 200c replaces the used tool, the grabbing mechanism 430c can transfer the used tool replaced by the machining device 200c to the second storage area 423c, so as to realize centralized recovery of the used tool and facilitate subsequent handling and other operations. In this way, the automation level of the tool change buffer platform 400c can be improved, and the human input during tool change of the machining device 200c can be saved.

[0157] Optionally, the first storage area 421c is provided with a first conveying assembly 422c for supporting and conveying the tool assembly to a preset position of the first storage area 421c, and the second storage area 423c is provided with a second conveying assembly 424c for supporting and conveying the tool assembly to a preset position of the second storage area 423c. The tool assembly includes a tool and a tool seat for accommodating and supporting the tool, or the tool assembly includes a tool and a tool box for storing the tool.

[0158] The preset position of the first storage area 421c refers to a position facilitating the grabbing of the tool assembly by the grabbing mechanism 430c or a position meeting the close arrangement of multiple tool assemblies, for example, a position close to the grabbing mechanism 430c on the first storage area 421c, and the preset position of the second storage area 423c refers to a position away from the grabbing mechanism 430c on the second storage area 423c or a position meeting the close arrangement of multiple tool assemblies. The tool in the tool assembly can be a to-be-used tool or a used tool, that is, the tool assembly can be a to-be-used tool assembly or a used tool assembly.

[0159] That is, the tool assembly to be used can be placed on the first conveying assembly 422c, the first conveying assembly 422c conveys the tool assembly to be used towards the direction close to the grabbing mechanism 430c, so that the grabbing mechanism 430c can transfer the tool assembly to be used to the machining device 200c, which can reduce the difficulty of the grabbing mechanism 430c to transfer the tool assembly to be used. In addition, the grabbing mechanism 430c can transfer the tool assembly used on the machining device 200c to the second conveying assembly 424c of the second storage area 423c, the second conveying assembly 424c conveys the tool assembly used away from the grabbing mechanism 430c, so that the tool assembly used can be avoided to be stacked in the area close to the grabbing mechanism 430c, and the grabbing mechanism 430c can place the tool assembly used in the area close to the grabbing mechanism 430c on the second storage area 423c, which can reduce the difficulty of the grabbing mechanism 430c to release the tool assembly used. In addition, the first conveying assembly 422c and the second conveying assembly 424c can automatically convey the tool assembly to the arrangement position, so that the plurality of tool assemblies can be arranged in the first storage area 421c or the second storage area 423c.

[0160] Therefore, the difficulty of the grabbing mechanism 430c to transfer the tool assembly can be reduced, and the working radius of the grabbing mechanism 430c can be shortened, so that the interference risk of the grabbing mechanism 430c during the transfer process can be reduced. In addition, the tool seat can accommodate the tool, which can improve the safety of the tool during the transfer process. In a specific example, referring to the figure, a plurality of tool boxes are arranged on the tool seat in sequence, and each tool box is used to place a specified number and type of tools. Therefore, the tool assembly can be customized to arrange the tools according to the tool requirement of the machining device 200c, which can improve the application range of the tool assembly. In addition, the first conveying assembly 422c and the second conveying assembly 424c can convey the tool seat to convey the plurality of tool boxes at the same time, and the grabbing mechanism 430c can transfer the tool seat to transfer the plurality of tool boxes at the same time, which can improve the transfer efficiency of the tool. Alternatively, the tool box is directly placed on the first conveying assembly 422c and the second conveying assembly 424c, and the grabbing mechanism 430c can place the tool box in the corresponding tool seat.

[0161] Specifically, the first conveying assembly 422c includes a belt conveying mechanism or a roller conveying mechanism, and the second conveying assembly 424c includes a belt conveying mechanism or a roller conveying mechanism.

[0162] That is, the first conveying assembly 422c and the second conveying assembly 424c can include a belt conveying mechanism 10a, and the tool assembly can be conveyed by the belt conveying mechanism. Of course, the first conveying assembly 422c and the second conveying assembly 424c can also include a roller conveying mechanism, so that the tool assembly can be conveyed by the roller conveying mechanism. Therefore, the stability of the tool seat conveying can be ensured.

[0163] Optionally, the placing table 420c is provided with a boss 425c, the grabbing mechanism 430c is arranged on the boss 425c, and the first storage area 421c and the second storage area 423c are located on opposite sides of the boss 425c along the first direction S1. That is, the first storage area 421c, the boss 425c and the second storage area 423c are arranged along the first direction S1, the first storage area 421c is located on one side of the boss 425c along the first direction S1, and the second storage area 423c is located on the other side of the boss 425c along the first direction S1 away from the first storage area 421c. The boss 425c is located between the first storage area 421c and the second storage area 423c.

[0164] Therefore, the interference between the first storage area 421c and the second storage area 423c can be well avoided, so as to avoid the tool changing error caused by the confusion between the to-be-used tool and the used tool, and the grabbing mechanism 430c located on the boss 425c is located between the first storage area 421c and the second storage area 423c, so that the working range of the grabbing mechanism 430c can cover the first storage area 421c and the second storage area 423c at the same time, thereby saving the number of grabbing mechanisms 430c and reducing the production cost of the tool changing and caching platform 400c. In addition, the grabbing mechanism 430c is located at a higher position compared with the first storage area 421c and the second storage area 423c, so that the interference to the movement of the grabbing mechanism 430c can be well avoided, thereby improving the reliability of the tool changing and caching platform 400c.

The mobile carrier 510c can adopt an AGV (Automatic Guided Vehicle), and a plurality of mobile carriers 510c can be provided.

[0166] Therefore, the fourth transfer trolley 500c can better transport the to-be-used tool to the tool changing and caching platform 400c and move the used tool on the tool changing and caching platform 400c, so that the automation level of the tool changing and caching system can be improved, and the labor input during the tool changing process of the machining equipment 200c can be saved.

[0167] Specifically, the mobile carrier 510c can move on the ground, so that the moving flexibility and movable range of the fourth transfer trolley 500c can be improved. The tool assembly can be better supported by the storage rack 520c and the third conveying assembly 530c, so that the fourth transfer trolley 500c can be moved to the tool changing and caching platform 400c after loading the to-be-used tool according to the tool changing demand of the machining equipment 200c and is connected with the first storage area 421c, so that the loaded to-be-used tool can be transmitted to the first storage area 421c under the driving of the third conveying assembly 530c, so that the to-be-used tool can be transferred to the machining equipment 200c by the grabbing mechanism 430c for the machining equipment 200c to change. When the used tool on the second storage area 423c needs to be moved, the fourth transfer trolley 500c moves to the side of the second storage area 423c of the tool changing and caching platform 400c and is connected with the tool changing and caching platform 400c, and then the used tool on the second storage area 423c is conveyed to the storage rack 520c by the third conveying assembly 530c, and the fourth transfer trolley 500c is driven to the tool recycling point by the mobile carrier 510c.

[0168] The third conveying assembly 530c includes a belt conveying mechanism 10a or a roller conveying mechanism. Therefore, the stability of the tool conveying can be better ensured.

Therefore, the conveying capacity of the third conveying assembly 530c can be better improved, that is, the third conveying assembly 530c can convey a plurality of tools at the same time, and the driving force of the third conveying assembly 530c is stronger, which is beneficial to improving the conveying efficiency of the tool. Secondly, the plurality of belt conveying mechanisms 10a can be synchronously driven. Therefore, the stability and efficiency of the third conveying assembly 530c can be improved.
