[0002] As a supplier of small and medium-sized parts, we mainly undertake the manufacturing of parts such as bolts, cover nuts and slot wedges. There are many types of these parts, and the production plan fluctuates greatly, which makes scheduling complex. The current project technology and production scheduling methods cannot respond quickly and dynamically. The specific manifestations are as follows: 1. The production and operation process is not transparent. Production site data and quality inspection data are transmitted through paper records, and traceability needs to be improved. 2. Some of the equipment in the existing workshop is outdated, and quality stability is affected by human factors. Assembly upgrades are needed, and automation and digital transformation are needed to improve processing accuracy and efficiency. 3. The existing inventory management model requires a large storage area. At the same time, there is no real-time record of material collection and release, and there is a lack of full life cycle management of material manufacturing and warehousing.

DETAILED DESCRIPTION

[0017] In the description of this specification, it should be noted that if the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. appear, the orientation or position relationship indicated is based on the orientation or position relationship shown in the drawings, or is the orientation or position relationship in which the product of this specification is usually placed when used. It is only for the convenience of describing this specification and simplifying the description, and does not indicate or imply that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be understood as a limitation on this specification.

[0018] Furthermore, the use of terms such as "horizontal" and "vertical" in this specification does not necessarily imply that a component must be absolutely horizontal or suspended, but rather that it can be slightly tilted. For example, "horizontal" simply refers to a direction that is more horizontal than "vertical," and does not imply that the structure must be completely horizontal, but rather that it can be slightly tilted.

[0019] In the description of this specification, it should also be noted that, unless otherwise clearly stipulated and limited, the terms "setting", "installation", "connection" and "connection" should be understood in a broad sense. For example, the connection can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be a connection between the internal parts of two components.

[0020] Example 1 like Figure 1-Figure 5 As shown, a flexible intelligent production system for bolts, cover nuts, and slot wedges includes a production control system 1, a three-dimensional warehouse 2, an AGV 3, and multiple production lines; the details are as follows.

[0021] In this embodiment, the production control system 1 can automatically import or manually input production orders; the production control system 1 is connected to the three-dimensional warehouse 2 and multiple production line signals, that is, the production control system 1 transmits the production order to the warehouse control system 21 of the three-dimensional warehouse 2 and the production line corresponding to the production order.

[0022] In this embodiment, the three-dimensional warehouse 2 has a scheduling stacker 22, a warehouse management system 21 and an entry and exit handover position 23. The command input end of the warehouse management system 21 is signal-connected to the command output end of the production management system 1, that is, the warehouse management system 21 re-obtains the production order from the production management system 1, and then parses the production order to determine the specifications of the blank parts required to produce the corresponding products, and determines the position of the cargo box 17 containing the blank parts in the three-dimensional warehouse 2 according to the specifications of the blank parts; the command output end of the warehouse management system 21 is signal-connected to the scheduling stacker 22 and AGV3, that is, the warehouse management system 21 sends the corresponding scheduling instruction to the scheduling stacker 22, and the scheduling stacker 22 dispatches the cargo box 17 containing the blank parts to the entry and exit handover position 23; AGV3 simultaneously obtains the handling instruction from the warehouse management system 21, and AVG transports the cargo box 17 (containing the blank parts) at the entry and exit handover position 23 to the loading station 7 of the corresponding production line.

[0023] It should be noted that the cargo frame 17 can accommodate materials of the same type but different sizes.

[0024] In this embodiment, the multiple production lines include at least a first production line 4 for producing large bolts, a second production line 5 for producing small bolts and cover nuts, and a third production line 6 for producing slot wedges. The large bolts and small bolts have different size specifications; there are also multiple different size specifications in the large bolts, small bolts, and cover nut products. For example, the blank specifications for producing large bolt products are "diameter range 85-130mm, length 510-980mm", the blank specifications for producing small bolt products are "diameter range 30-85mm, length 150-510mm", and the blank specifications for producing cover nut products are "diameter range 35-135mm, length 55-200mm, or diameter range 145-240mm, length 205-340mm".

[0025] It should be noted that for the first and second production lines 4 and 5, the cargo frame 17 includes a pallet 19 having a tray body, within which a first mounting member 192 and a second mounting member 193 are slidably connected in the same direction. The first mounting member 192 can slide away from and toward each other to accommodate the lengths of large bolt blanks of varying specifications. V-shaped support members 191 of the same specification are removably mounted on both the first and second mounting members 192 and 193. The V-shaped angles of the support members 191 of varying specifications vary, and by replacing the support members 191, the V-shaped angles can be varied to accommodate the diameters of large bolt blanks of varying specifications. Both the first and second mounting members 192 and 193 are detachably connected to the tray body. The first and second mounting members 192 and 193 can be removed, allowing blanks of small bolts and cover nuts to be directly stacked within the pallet 19. Thus, adjustment of the pallet 19 can accommodate different material sizes, increasing the flexibility of the entire production system.

[0026] For the tray 19, a slide groove can be opened in the tray 19, the first mounting member 192 is installed on the first slide 196, and the second mounting member 193 is installed on the second slide 195. The first slide 196 and the second slide 195 are both slidably connected to the slide groove to realize the sliding connection between the first mounting member 192 and the second mounting member 193 disk body.

[0027] For the third production line 6, the cargo frame 17 includes a material frame having a plurality of material levels 18 arranged in an array. The blanks for producing slot wedges are placed in the material levels 18. Each material level 18 can hold one blank. The cross-sectional dimensions of the material level 18 can be adjusted to accommodate the production of slot wedges of different specifications and sizes, thereby increasing the flexibility of slot wedge production.

[0028] In summary, the flexible intelligent production system can process materials of the same type and different sizes thanks to the design of the cargo frame 17.

[0029] Furthermore, each production line has its own production line control system 14, such as the first production line 4 has a first production line control system 14, the second production line 5 has a second production line control system 14, and the third production line 6 has a third production line control system 14; the production line control system 14 is connected to the production control system 1 by signal, obtains the production order from the production control system 1, and determines the required blank specifications based on the production order; matches the required blank specifications with the blank specifications on the loading station 7; if the blank specifications match, the corresponding product is produced; if the blank specifications do not match, the corresponding product is not produced.

[0030] To sum up, both the production control system 1 and the production line control system 14 can record production site data, making the production and operation process transparent and traceability improved; the entire production process is fully automated, improving product production accuracy and efficiency; by utilizing the information interaction between the warehouse control system 21 and the production control system 1, real-time recording of material access and storage records is achieved, improving the manufacturing and warehousing life cycle management of materials; that is, by constructing a common digital production line for bolts, cover nuts and slot wedges, the small and medium-sized batch production needs of core parts products with multiple varieties and sizes can be met, the manufacturing efficiency of products can be improved, manual intervention in the manufacturing process can be reduced, the controllability and transparency of production can be enhanced, the quality and delivery stability can be improved, and the production cost can be reduced.

[0031] Example 2 Based on Example 1, a specific implementation method that can be implemented is further proposed.

[0032] A feasible implementation method is that the cargo frame 17 is provided with an RFID card for storing the specifications of the blank parts, and each production line loading station 7 is provided with an RFID reader / writer, which can read the specification information of the blank parts in the RFID card and write the specification information of the blank parts into the RFID card, and the RFID reader / writer is connected to the corresponding signal generated by the production line control system 14. After the RFID reader / writer reads the specification information of the blank parts, it transmits the blank part information to the corresponding production line control system 14, and the production line control system 14 matches the specification information of the blank parts with the specifications of the blank parts required by the production order.

[0033] A feasible implementation method is that the first production line 4 and the second production line 5 both have a visual guidance device 8. Since the blank of the bolt is a cylinder, the visual guidance device 8 of the first production line 4 and the second production line 5 is preferably a device that can provide 3D visual guidance; since the blanks for producing slot wedges are mostly rectangular, they are placed in the material position 18 of the cargo frame 17, so the visual guidance device 8 of the third production line 6 can be a planar visual guidance; the visual guidance device 8 is installed directly above the loading station 7, and the installation height is adjustable (which can be achieved through a guide rail), and it can obtain image information of the blank at the loading station 7, thereby obtaining the position information of the blank in the cargo frame 17; in the same production line, the visual guidance device 8 is connected to the production line control system 14 of the production line by signal, that is, the image information is transmitted to the production line control system 14, and the production line control system 14 controls the handling robot group 9 to transport the blank to the next production process according to the image information.

[0034] In one feasible embodiment, the first production line 4, the second production line 5, and the third production line 6 each further include a handling robot group 9 and a production machine tool group. The handling robot group 9 can be composed of at least one handling robot, which can be a 6-axis articulated robot, model R-200ic-210F or M-900iB-360. The handling robot group 9 is assembled between the corresponding loading station 7 and the production machine tool group in the production line, and the loading station 7 and the production machine tool group are both installed within the handling range of the handling robot group 9. The handling robot group 9 and the production machine tool group are both connected to the production line control system 14 by signal. That is, the handling robot group 9 can transport the blanks at the loading station 7 to the production machine tool group for processing under the control of the production line control system 14. Specifically, for the first production line 4, the second production line 5, and the third production line 6, the handling robot in the handling robot group 9 located between the loading station 7 and the production machine tool group performs handling based on image information obtained by the corresponding production line control system, and the production machine tool group performs precise processing of the product under the control of the production line control system 14.

[0035] It should be noted that the first production line 4 , the second production line 5 , and the third production line 6 can be equipped with sliding rails as needed, and the handling robots in the handling robot group 9 can be installed on the sliding rails to adapt to the layout of each equipment.

[0036] A feasible implementation method is that the first production line 4, the second production line 5, and the third production line 6 are respectively further provided with a positioning device 12, which is installed in the handling range of the handling robot group 9 and is located between the loading station 7 and the production machine tool group. The positioning device 12 can position the blank to ensure the assembly accuracy of the blank after it is transported by the handling robot group 9 and enters the production machine tool group; specifically, the positioning device 12 has a positioning plate, and the end face of the blank is affixed to the positioning plate. Based on the positioning plate, the position of the handling robot group 9 contacting the blank can be determined, further ensuring the installation accuracy of the blank installed in the production machine tool group, and further ensuring the processing accuracy; on the other hand, for blanks of different sizes, this method can achieve the same position of the handling robot group 9 contacting the blank to the end face of the blank (the end face affixed to the positioning plate), thereby achieving the same assembly of blanks of different specifications in the production machine tool group, that is, the end face of the blank (the end face affixed to the positioning plate) can be used as the base surface for assembly.

[0037] Furthermore, for the first production line 4 and the second production line 5, since the blank of the bolt is a cylinder, the positioning device 12 is a positioning platform, which has a supporting surface for supporting the blank. The supporting surface is inclined relative to the horizontal plane, and the positioning surface is perpendicular to the supporting surface and perpendicular to the inclination direction of the supporting surface, so that the blank can fit with the positioning plate under the action of its own gravity.

[0038] Furthermore, for the third production line 6, since the blank of the slot wedge is a polygonal cylinder, the positioning device 12 can be a conveyor table, and the positioning plate is assembled at the end face downstream of the conveyor table, and the blank of the slot wedge can be fitted with the positioning plate under the transportation action of the conveyor table.

[0039] A feasible implementation method is that the first production line 4, the second production line 5, and the third production line 6 also include a cleaning station and a unloading station 15 respectively, and the cleaning station and the unloading station 15 are both installed in the handling range of the handling robot group 9, that is, the handling robot group 9 can transport materials (blanks or finished products) to the cleaning station or / and the unloading station 15, and can also move materials out from the cleaning station or / and the unloading station 15; and are located downstream of the production machine tool group in sequence, that is, the materials at the cleaning station and the unloading station 15 are finished products, and the blanks are processed by the production machine tool group to form corresponding products, such as large bolts, small bolts, cover nuts or slot wedges; the products are transported to the cleaning station, and burrs, metal chips and other impurities are removed at the cleaning station, and then transported to the unloading station 15 by the handling robot group 9.

[0040] Furthermore, the products on the unloading station 15 can be transported to the stereoscopic warehouse 2 for storage again through AGV3, or can be quality inspected through random inspection. The process after the unloading station 15 is not the focus of this solution and will not be explained in detail here.

[0041] In one feasible implementation, the loading station 7 and unloading station 15 of the third production line 6 are equipped with proximity sensors 16 for detecting the presence of a cargo frame 17. These proximity sensors 16 are signal-connected to the production line control system 14 of the third production line 6. When a cargo frame 17 is placed at the loading station 7 or unloading station 15, the proximity sensors 16 receive a signal, which is then transmitted to the production line control system 14 of the third production line 6. After the production line control system 14 confirms the presence of a cargo frame 17 at the loading station 7, it uses a handling robot group to move the slot wedge blank to the positioning device 12. After the production line control system confirms the presence of a cargo frame 17 at the unloading station 15 and that all material positions 18 within the cargo frame 17 contain slot wedges, it feeds back the signal to the production control system 1, which then notifies the AVG 3 to proceed with the transportation.

[0042] A feasible implementation method is that the production machine tool group includes a first processing machine tool 10 and a second processing machine tool 11 arranged in sequence. The first processing machine tool 10 is used as a machine tool for rough processing or processing one end or one side of the blank, and the processing basis is the blank; the second processing machine tool 11 is used as a machine tool for fine processing or processing the other end or the other side of the blank, and the processing basis is the product output by the first processing machine tool 10; a workpiece buffer table 13 is installed between the first processing machine tool 10 and the second processing machine tool 11, and the buffer table 13 is used to solve the contradiction between the processing speeds of the first processing machine tool and the second processing machine tool. Usually, the processing speed of the first processing machine tool 10 is faster than that of the second processing machine tool 11. Therefore, when there is no new processing position in the second processing machine tool 11, the product processed by the first processing machine tool 10 can be placed on the buffer table 13 for temporary storage; the first processing machine tool 10, the workpiece buffer table 13, and the second processing machine tool 11 are all installed within the handling range of the handling robot group 9, that is, the material handling is realized by the handling robot group 9.

[0043] It should be noted that, for the first production line 4 , the second production line 5 , and the third production line 6 , a transport robot can be installed between the first processing machine tool 10 and the second processing machine tool 11 to transfer materials in the first processing machine tool 10 to the second processing machine tool 11 .

[0044] Example 3 A flexible intelligent production process for bolts, cover nuts, and slot wedges, using the flexible intelligent production system for bolts, cover nuts, and slot wedges described in any one of the embodiments 1-2, includes the following steps: S1: Production control system 1 obtains the production order and sends it to the three-dimensional warehouse 2 and the corresponding production line; S2: After receiving the production order, the warehouse control system 21 sends a dispatch instruction to the dispatch stacker 22 according to the production order. The dispatch stacker 22 dispatches the cargo frame 17 containing the blank to the inbound and outbound transfer position 23 and sends a handling instruction to the AGV 3; S3: After receiving the transport instruction, AGV3 transports the cargo frame 17 containing the blank from the inbound and outbound transfer position 23 to the loading station 7 of the corresponding production line; S4: After the production line control system 14 in the corresponding production line obtains the corresponding production order, it determines the specifications of the blank and matches them with the specifications of the blank on the loading station 7; if the specifications of the blank match, the corresponding product is produced; if the specifications of the blank do not match, the corresponding product is not produced.

[0045] The present invention is not limited to the aforementioned specific embodiments, but extends to any new features or any new combination disclosed in this specification, as well as any new method or process steps or any new combination disclosed.
