Description

Technical Field

[0001] The invention relates to the field of manufacturing systems, and in particular to a flexible manufacturing system for an unmanned workshop. Background Art

[0002] With the development and popularization of automated production, the production efficiency of manufacturing has also been managed in a refined manner. However, the existing automated production generally adopts an assembly line structure to achieve full-process automated production or assembly, thereby improving production efficiency.

[0003] Correspondingly, its production space requirements are higher, and the area occupied is also larger. At the same time, in actual production, when a problem occurs or the efficiency is reduced in one of the processes, its production efficiency will also decrease exponentially. Therefore, there are certain defects in the manufacturing logic.

[0004] At the same time, when the production line needs to be changed or other models need to be produced, the adjustment cycle is long, that is, multiple processes need to be adjusted one by one and the connection of each process needs to be achieved. The debugging cycle is long, so the disadvantages are also more obvious;

[0005] Moreover, this type of production line is generally non-standard customized, so there are great limitations in actual production applicability. Therefore, the cost is high and the investment cycle is long, which affects the efficiency of the equipment.

[0006] Moreover, in an actual production line, one of the machines is a general-purpose machine, such as a marking machine. When one production line is used up, it needs to be moved to the next production line for use. This situation is more troublesome to use and the movement is also more cumbersome. Of course, there are also those who purchase multiple machines, so the corresponding production cost will increase accordingly, and the rate of return on machine purchase will also decrease, affecting the enthusiasm for production. Summary of the invention

[0007] The main purpose of the present invention is to propose a flexible manufacturing system for an unmanned workshop, which aims to achieve flexible coordination between various processes through the cooperation between the production end of the flexible manufacturing system and the transfer robot, thereby improving assembly efficiency or production efficiency. The control system can adjust the workload between various processes according to the efficiency difference between various processes, thereby achieving high efficiency and high turnover rate.

[0008] To achieve the above object, the present invention proposes a flexible manufacturing system for an unmanned workshop, comprising:

[0009] Production end, the production end is provided with 1+N, and each production end is provided with at least one unit, the layout of each production end is flexibly arranged by the production process and the spatial area, the production end can be movably set or fixedly set, and each production end has a predetermined production rhythm;

[0010] The transfer robot is used to load and unload materials from multiple units at the production end.

[0011] A transfer robot, which is used to circulate between various production ends and realize the turnover of materials or production ends;

[0012] A flexible control device, which can obtain production data of the production end, position data of the transfer robot and the transfer robot, and can control and regulate the production rhythm of the production end;

[0013] When there is a difference in production rhythm between production ends, the flexible control device controls the ratio or production efficiency between the working units and the idle units at the production ends to ensure that the production rhythm between the various production ends is at a predetermined value.

[0014] In the actual design, the production end can assemble materials or produce parts of materials, and then assemble them. Unlike the existing flexible manufacturing system, the production end of this design can be mobile or fixed. When it is mobile, the production end can be set on the transfer robot, thereby realizing the composition of the material production chain.

[0015] The production chain can produce multiple different materials together or multiple material production chains can share one production end, thereby effectively reducing the purchase cost of the machine while ensuring production efficiency;

[0016] The production chains can be arranged in an array, with multiple long production chains in parallel or in a herringbone pattern, thereby improving production efficiency while reducing material turnover time, thereby improving production efficiency;

[0017] Specifically, the transfer robot can be set between two production ends to achieve rapid production of materials. At the same time, even when the production of a certain material stops, the production end can be effectively improved to cooperate with the production of the next material, thereby reducing the idle rate of the production end and improving the return on investment of the equipment;

[0018] At the same time, the transfer robot can realize the transfer of production end and also realize material production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] like Figures 1 to 6 As shown, a flexible manufacturing system for an unmanned workshop includes:

[0031] Production end, the production end is provided with 1+N, and each production end is provided with at least one unit, the layout of each production end is flexibly arranged according to the production process and the spatial area, and the production end can be movably set or fixedly set;

[0032] The transfer robot is used to load and unload materials from multiple units at the production end.

[0033] A transfer robot, which is used to circulate between various production ends and realize the turnover of materials or production ends;

[0034] A flexible control device, which can obtain production data of the production end, position data of the transfer robot and the transfer robot, and can control and regulate the production rhythm of the production end;

[0035] When there is a difference in production rhythm between production ends, the flexible control device controls the ratio or production efficiency between the working units and the idle units at the production ends to ensure that the production rhythm between the various production ends is at a predetermined value.

[0036] In the actual design, the production end can assemble materials or produce parts of materials, and then assemble them. Unlike the existing flexible manufacturing system, the production end of this design can be mobile or fixed. When it is mobile, the production end can be set on the transfer robot, thereby realizing the composition of the material production chain.

[0037] The production chain can produce multiple different materials together or multiple material production chains can share one production end, thereby effectively reducing the purchase cost of the machine while ensuring production efficiency;

[0038] The production chains can be arranged in an array, with multiple long production chains in parallel or in a herringbone pattern, thereby improving production efficiency while reducing material turnover time, thereby improving production efficiency;

[0039] Specifically, the transfer robot can be set between two production ends to achieve rapid production of materials. At the same time, even when the production of a certain material stops, the production end can be effectively improved to cooperate with the production of the next material, thereby reducing the idle rate of the production end and improving the return on investment of the equipment;

[0040] At the same time, the transfer robot can realize the transfer of production end and also realize material production efficiency.

[0041] Specifically, the production end is manufacturing equipment, assembly equipment or testing equipment, and the manufacturing equipment is plastic molds, CNC equipment, and welding equipment.

[0042] Specifically, the production end is manufacturing equipment, assembly equipment and / or testing equipment, and the manufacturing equipment is plastic molds, CNC equipment and / or welding equipment.

[0043] The areas can be divided according to the characteristics of the production end, such as gas pollution, noise, etc., that is, the production ends can be in areas that do not interfere with each other, thereby reducing pollution or interference; and different equipment can be combined or coordinated with each other. When flexibly coordinated, for example, a welding device can be connected to different assembly equipment at the same time.

[0044] Of course, in the field of testing equipment, when a material needs to be tested for multiple parameters, multiple production ends are required for testing. Then the duration of different processes is also different. The corresponding flexible control device can add equipment at the location where the process duration is longer, thereby improving the efficiency of the production end. Then the next production end can guarantee its predetermined efficiency, effectively improving the rhythm of the entire equipment.

[0045] In an embodiment of the present invention, the flexible control device is a virtual model, and the virtual model is connected to each production end and the transfer robot in a one-to-one correspondence and displayed in the virtual model one by one.

[0046] The virtual model can monitor the data of each production end and the transfer robot as well as the production position in real time, and obtain the production relationship and adjust the production rhythm through the virtual model.

[0047] In one of the designs, a virtual model can be established, and the production data of each production end (such as qualification rate, production materials, and machine parameters, etc.), production items, and production rhythm can be recorded; of course, it is best if each material has a traceability code, so that in automated production, when defects or problems with the material are discovered in time, they can be modified or improved immediately.

[0048] And by simulating production between the virtual model and the production end, the predetermined production value is obtained to ensure accurate production data. When the virtual model continues to learn (that is, obtain real-time production data and adjust the predetermined production rhythm and production materials), the actual production value is adjusted;

[0049] This allows you to continuously obtain accurate production returns;

[0050] When the data has a good reference model, when it is transferred to the production end of other materials, the virtual model can also obtain more accurate production rhythm or production data, thereby effectively improving the value of the flexible manufacturing system;

[0051] Of course, specifically, the virtual model corresponds one-to-one with the production end and the transfer robot, which can realize real-time monitoring of the data and stability of the production end and realize unmanned production.

[0052] Specifically, the production end can mix multiple materials for production or produce a single material, that is, it can be mixed production or single material production. For example, if two materials both need to use the same parts or the same detection device, then the materials can use the production end together, thereby reducing the procurement cost of the equipment and improving the stability of the equipment while ensuring the production rhythm.

[0053] In an embodiment of the present invention, the transfer robot is a workstation robot or a multi-axis manipulator;

[0054] The transfer robot includes an AGV vehicle equipped with a transfer silo.

[0055] The transfer robot is a workstation robot, a ground rail robot, a mobile composite robot or a multi-axis manipulator.

[0056] Of course, the multi-axis manipulator can also be installed on the AGV cart, and the use of the silo can achieve stable and rapid turnover of materials, thereby improving the material turnover rate.

[0057] In actual automated production, the silo is the key to design, thereby ensuring work efficiency.

[0058] The workstation robot is preferably a fixed structure (such as a clamping device, a multi-axis manipulator, etc.); the ground rail robot is mainly used for point-to-point material transfer; the transplanting device is mainly used for point-to-face, where the face is point-to-face or face-to-point, and the face can be understood as multiple units at the production end or multiple production ends.

[0059] Specifically, the virtual model can store data and information on the production side, including equipment parameter data, production items, and production rhythm on the production side.

[0060] When the production cycle is less than 60S, a workstation robot is used to load and unload materials in one unit or between two units at each production end;

[0061] When the production cycle is less than 60 seconds and less than 300 seconds, rail robots are used to load and unload materials between multiple units at each production end;

[0062] When the production cycle is less than 300S, mobile composite robots are used to load and unload materials between multiple units at each production end.

[0063] Specifically, the production end data includes production end information, parts information, and material completion time, wherein the material completion time includes the material production time and / or material assembly time, and the material completion time defines the production tact. When the number of units is 1+N, the production tact is 1 / 1+N. That is, the number of units can reduce the production tact, thereby ensuring the consistency of the tact between each production end. Although the tact of the unit can be controlled singly, its production efficiency has an upper limit, and when the upper limit is exceeded, its unqualified rate will also decrease accordingly;

[0064] Therefore, the requirements for testing will also increase, and the corresponding testing equipment required in the production end will also increase. Therefore, through the virtual model, the productivity can be accurately known, and the return on investment can be obtained.

[0065] In an embodiment of the present invention, a positioning structure or an origin positioning device is provided between the transfer robot and the production end, thereby ensuring the production accuracy between each process to ensure the stability of production.

[0066] When the manufacturing system is an assembly device, the production end includes a manufacturing supply end and an assembly end, and multiple manufacturing supply ends cooperate with a single assembly end.

[0067] When the manufacturing system is a production equipment, in the actual production end, the production of a material needs to go through multiple production ends, such as CNC production end and sheet metal production end. However, in the actual production process, when the processing time of one of the production ends is long, the production rhythm can be effectively reduced by increasing the number of units at the production end, thereby achieving the production needs of the next process, that is, ensuring that the rhythm is consistent or appropriate.

[0068] The production end, transfer robot and flexible control device use an internal local area network or a 5G+WIFI network to achieve data interaction.

[0069] exist Figure 1 In the embodiment, the production end ① of the flexible manufacturing system is provided with multiple units, and the production end ② has only one unit. In actual processing, the production rhythm of the production end ① is slower, so adding units can make the production rhythm of the production end ① and the production end ② consistent, and transfer robots (such as multi-axis manipulators) can also be used between the production ends.

[0070] exist Figure 2 In the embodiment, the flexible manufacturing system includes multiple different production lines ①, ②, and ③, but the multiple production lines share a production line in one of the processes, wherein the production line is arranged on a transfer robot (such as a ground rail robot), so as to realize switching between the various production lines, wherein the shared production line can be a marking machine, a packaging machine, etc.

[0071] exist Figure 3In the embodiment, the flexible manufacturing system includes multiple different production lines ①, ②, and ③, where the materials or processes of one production end can be suitable for different production lines and can be used as a common production end to supply different production lines, thereby reducing the procurement cost of equipment and improving the turnover and storage of materials. At this time, a single production end corresponds to different production line production ends (where the production ends are located in different production lines and have different processes). At this time, it is more convenient to load and unload materials by using an AGV cart in conjunction with a transfer robot located at the production end.

[0072] exist Figure 4 In the embodiment, the flexible manufacturing system is used to produce a mobile phone back panel.

[0073] The multiple units at the production end ① are die-casting equipment, which can be multiple processes or a single process, thereby realizing the sheet metal processing of the back plate;

[0074] The multiple units at the production end ② are fine grinding equipment, which can achieve fine processing of the initial processing of the back plate;

[0075] The multiple units at the production end ③ are CNC equipment, which perform deep processing on the back panel to form preliminary materials;

[0076] The multiple units at the production end ④ are spraying equipment, which perform the final processing on the back panel and form the finished product. The location distribution of each production end may not be distributed in sequence according to the assembly line, and the number of units at each production end may also be different. Among them, the CNC equipment is generally the one with the slowest production rhythm. Therefore, the number of units at this production end can be increased at this time to ensure the consistency of the production rhythm between each production end.

[0077] For example, each unit within the production end ① can use a transfer robot to realize material processing between each unit. When the material processing at the production end ① is completed, it can be placed in the unloading bin or the transfer robot can directly place the material in the transfer bin of the AGV robot, and then the AGV robot moves the material to the production end ②, and then the transfer robot at the production end ② moves the material from the transfer bin to the loading bin of the production end ②.

[0078] Figure 5 and Figure 6 The present invention is an embodiment of the cooperation between a transfer robot and a transfer robot.

[0079] The transfer robot may be a multi-axis manipulator;

[0080] Of course, the transfer robot can also be a conveyor belt, such as the combination of an AGV trolley and a conveyor belt (generally, the transport quantity of this structure is small), or the silo and the transfer robot can be integrated into the transfer robot;

[0081] The transfer robot is preferentially used as a silo (which can be a transfer silo), and the loading and unloading robot is arranged on the production end (the position of the loading and unloading robot can also be arranged with upper and lower silos), and then the materials are moved to the transfer robot.

[0082] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
