[0035] Please refer to Figures 1 to 11 , is a CNC machining automatic production line of an embodiment of the invention, used for machining workpieces. Please refer to Figure 1 and Figure 2 The CNC machining automatic production line includes a conveying area 100, a processing area 200, a loading and unloading area 300, a conveyor line 400, a CNC machine tool 500 and a first AGV 600. The loading and unloading area 300 is located between the conveying area 100 and the processing area 200. The conveyor line 400 is provided in the conveying area 100, and the conveyor line 400 is used to convey the workpiece. The CNC machine tool 500 is provided in the processing area 200, and the CNC machine tool 500 is used to process the workpiece. The first AGV 600 is provided in the loading and unloading area 300, and the first AGV 600 is used to transfer the workpiece from the conveyor line 400 to the CNC machine tool 500, or to transfer the workpiece from the CNC machine tool 500 to the conveyor line 400.

[0036] In the above-mentioned CNC machining automatic production line, the conveyor line 400 is used to convey the workpiece, the CNC machine tool 500 is used to process the workpiece, and the first AGV600 is used to transfer the workpiece from the conveyor line 400 to the CNC machine tool 500, or to transfer the workpiece from the CNC machine tool 500 to the conveyor line 400, thereby realizing full automation and integration of workpiece transportation, loading, processing and unloading, with a high degree of automation, effectively reducing labor usage, reducing labor costs, improving work efficiency, and increasing production capacity.

[0037] Further, the conveying area 100, the loading and unloading area 300 and the processing area 200 are arranged in parallel, that is, the conveying area 100 and the processing area 200 are respectively located on opposite sides of the loading and unloading area 300. The conveying direction of the conveying line 400 is consistent with the length direction of the conveying area 100.

[0038] Since different processing techniques for different workpieces or different processing techniques for the same workpiece are completed by different CNC machine tools, there are multiple CNC machine tools 500, and multiple CNC machine tools 500 are arranged in parallel and spaced in the processing area 200, and the types of multiple CNC machine tools 500 are all different. It can be understood that multiple CNC machine tools 500 are used to complete different work tasks, that is, multiple CNC machine tools 500 are used to process workpieces with different processes. Multiple CNC machine tools 500 can work synchronously, that is, the CNC machining automatic production line can perform multiple tasks synchronously, effectively improving efficiency. Specifically in this embodiment, the number of CNC machine tools 500 is three, and the types of the three CNC machine tools 500 are all different.

[0039] The number of the first AGVs 600 is equal to the number of the CNC machine tools 500 , so when there are multiple CNC machine tools 500 , there are also multiple first AGVs 600 of the same number, and the multiple first AGVs 600 can synchronously execute different work tasks.

[0040] Please refer to Figure 3 and Figure 4 The first AGV 600 includes a first AGV body 610 and a first working module 620. The first working module 620 is detachably connected to the first AGV body 610. The first AGV body 610 is used to drive the first working module 620 to walk. The first working module 620 is used to complete the specified work task. The first working module 620 can be a single-arm module 621 or a double-arm module 622. It can be understood that the single-arm module 621 is a single-arm manipulator, and the double-arm module 622 is a double-arm manipulator. By modularizing the functional structure of the first AGV 600, the first working module 620 with different functions can be switched on the first AGV body 610 according to the needs, so as to realize loading and unloading of different workpieces, effectively saving costs.

[0041] Please refer to Figure 8Specifically, a connection module 40 is provided on the top of the first AGV body 610. The first working module 620 is provided above the AGV, and a locking module 30 is provided on the bottom of the first working module 620, and the locking module 30 cooperates with the connection module 40 to lock. There are multiple connection modules 40, and multiple connection modules 40 are distributed at intervals on the top of the first AGV body 610. There are multiple locking modules 30, and the locking modules 30 are distributed at intervals on the bottom of the first working module 620, and the locking modules 30 and the connection modules 40 are locked one by one. By providing multiple locking modules 30 and multiple connection modules 40, and locking the locking modules 30 and the connection modules 40 one by one, the stability of the connection between the first working module 620 and the first AGV body 610 is effectively improved.

[0042] Please refer to Figure 3 and Figure 7 , further, an AGV top plate 611 is provided on the top of the first AGV body 610, specifically, the AGV top plate 611 is screwed to the top of the first AGV body 610. A plurality of connection modules 40 are mounted on the AGV top plate 23. A module bottom plate 623 is provided on the bottom of the first working module 620, specifically, the module bottom plate 623 is screwed to the bottom of the first working module 620. A plurality of locking modules 30 are mounted on the module bottom plate 623. During assembly, a plurality of connection modules 40 are first mounted on the AGV top plate 23, and then the AGV top plate 23 is mounted to the top of the first AGV body 610, a plurality of locking modules 30 are first mounted on the module bottom plate 623, and then the module bottom plate 623 is mounted to the bottom of the first working module 620. It can be understood that by modularizing multiple connection modules 40 and the AGV top plate 611 and then assembling them onto the first AGV body 610, and by modularizing multiple locking modules 30 and the module bottom plate 623 and then assembling them onto the first working module 620, assembly is convenient and efficient.

[0043] Please refer to Figure 8 and Fig. 9The locking module 30 includes a male seat 31 and a locking mechanism 32 disposed on the male seat 31. The male seat 31 is fixedly embedded in the module bottom plate 623 and is screwed to the module bottom plate 623. The connecting module 40 includes a female seat 41 and a buckle block 42. The female seat 41 is fixedly embedded in the AGV top plate 611 and is screwed to the AGV top plate 611. The female seat 41 is provided with a slot 411 plugged with the male seat 31. The buckle block 42 is disposed on the inner side wall of the slot 411. The buckle block 42 is used to buckle the locking mechanism 32. Specifically, during the process of installing the first working module 620 on the first AGV body 610, one end of the male seat 31 is inserted into the slot 411 of the female seat 41, and the locking mechanism 32 is buckled with the buckle block 42, so that the locking module 30 and the connecting module 40 are locked together, thereby locking the first working module 620 on the first AGV body 610.

[0044] Please refer to Figures 8 to 10 Further, the male seat 31 includes a shell 311 and a convex ring 312 arranged on one end of the shell 311, the convex ring 312 is connected to the shell 311, and a gap 313 is provided on the side wall of the convex ring 312, and the gap 313 runs through the inner and outer sides of the convex ring 312. The locking mechanism 32 includes a cam block 33, the cam block 33 is arranged in the gap 313, and the middle part of the cam block 33 is pivotally connected to the convex ring 312, that is, the cam block 33 can rotate relative to the convex ring 312. A buckle groove 421 is provided on the buckle block 42. When the locking module 30 and the connecting module 40 are in a locked state, the convex ring 312 is inserted into the slot 411, the shell 311 and the female seat 41 are fitted, and one end of the cam block 33 is buckled in the buckle groove 421.

[0045] Specifically in this embodiment, there are two gaps 313, which are respectively arranged on opposite sides of the convex ring 313; there are two cam blocks 33, which are respectively arranged in the gaps 313 and pivotally connected to the convex ring 313; there are two buckle blocks 42, which are respectively arranged on opposite sides of the slot 411; one ends of the two cam blocks 33 are respectively buckled into the buckle grooves 421 on the two buckle blocks 42, which is beneficial to strengthen the locking effect between the locking module 30 and the connecting module 40.

[0046] Please refer to Fig. 9 and Fig.10In some embodiments, the cam block 33 is arranged in an L shape. Specifically, the cam block 33 includes a rotating portion 331, a swinging portion 332 connected to the rotating portion 331, and a buckling portion 333 connected to the rotating portion 331. The rotating portion 331 is arranged in the gap 313 and is pivotally connected to the convex ring 312. The swinging portion 332 and the buckling portion 333 are respectively located at opposite ends of the rotating portion 331, that is, the swinging portion 332, the rotating portion 331 and the buckling portion 333 form an L-shaped structure. The swinging portion 332 extends into the convex ring 312. When the locking module 30 and the connecting module 40 are in a locked state, the buckling portion 333 extends to the outside of the convex ring 312 and buckles in the buckle groove 421. When the locking module 30 and the connecting module 40 are in an unlocked state, the buckling portion 333 is located in the gap 313. In this embodiment, the rotating portion 331, the swinging portion 332 and the buckling portion 333 are integrally formed.

[0047] In some embodiments, the locking mechanism 32 further includes an actuating assembly 34 for driving the cam block 33 to rotate. Specifically, the actuating assembly 34 is disposed in the housing 311, and one end of the actuating assembly 34 extends into the convex ring 312. The other end of the cam block 33 extends into the convex ring 312 and is movably connected to the actuating assembly 34. Specifically, the swinging portion 332 of the cam block 33 is movably connected to the actuating assembly 34. It can be understood that during the locking process, the actuating assembly 34 drives the swinging portion 332 to move, thereby driving the rotating portion 331 to rotate, thereby driving the buckling portion 333 to extend out of the convex ring 312 and buckle into the buckle groove 421.

[0048] Further, the actuating assembly 34 includes a lifting driving member 341 and a movable block 342 connected to the lifting driving member 341, one end of the movable block 342 is provided with a slot 347, the slot 347 is arranged along the circumference of the movable block 342, and the end of the movable block 342 provided with the slot 347 is located in the convex ring 312. One end of the cam block 33 extending into the convex ring 312 is buckled into the slot 347, that is, the swinging portion 332 is movably buckled into the slot 347. It can be understood that when the lifting driving member 341 drives the movable block 342 to make the swinging portion 332 move up and down, the rotating portion 331 rotates counterclockwise or clockwise relative to the convex ring 312, so that the buckling portion 333 of the cam block 33 rotates to the outside of the convex ring 312 and buckles into the buckling slot 421, or the buckling portion 333 of the cam block 33 is separated from the buckling slot 421 and rotated into the gap 313.

[0049] The lifting drive member 341 includes a rotary driver 343 disposed in the housing 311 and a screw rod 344 connected to the rotary driver. The rotary driver 343 is a motor. One end of the screw rod 344 extends into the convex ring 312. The movable block 342 is sleeved on the screw rod 344 and is threadedly connected with the screw rod 344. One end of the movable block 342 away from the slot 347 is movably inserted into the housing 311. A stopper 314 is disposed in the housing 311. The stopper 314 is disposed corresponding to the movable block 342. The stopper 314 is used to limit the rotation of the movable block 342. Therefore, when the rotary driver 343 drives the screw rod 344 to rotate, the movable block 342 has a tendency to rotate synchronously with the screw rod 344. However, due to the restriction of the stopper 314 on the movable block 342, the movable block 342 cannot rotate, so that the movable block 342 moves up and down along the axial direction of the screw rod 344, thereby driving the cam block 33 to rotate clockwise or counterclockwise.

[0050] Please refer to Fig. 9 and Fig.11 Specifically, a limit plate 345 is provided at one end of the movable block 342 away from the slot 347, and the limit plate 345 has straight edges 346 on opposite sides. Fig. 9 There are two stop blocks 314, which are arranged on the bottom of the shell 311, and the stop blocks 314 are in contact with the straight edges 346 of the limit plate 345 respectively. The limit plate 345 is restricted by the stop blocks 314 so that the limit plate 345 cannot rotate. Even if the movable block 342 cannot rotate with the screw rod 344, the rotational motion is converted into linear motion, so that the movable block 342 moves up and down along the axial direction of the screw rod 344.

[0051] Please refer to Figure 8 In some embodiments, a locating pin 35 is provided on the top of the male seat 31, and a locating hole 412 is provided on the female seat 41, and the locating pin 35 is correspondingly plugged into the locating hole 412. Specifically, the locating pin 35 is provided on one end of the shell 311 facing the female seat 41. It can be understood that when the locking module 30 and the first working module 620 are in a locked state, the bottom of the shell 311 fits with the top of the female seat 41, and the locating pin 35 is inserted into the corresponding locating hole 412, which effectively improves the stability of the locking between the locking module 30 and the connecting module 40. Further, the number of the locating pins 35 is two, and the two locating pins 35 are respectively arranged on opposite sides of the bottom of the shell 311, that is, the two locating pins 35 are arranged at intervals around the convex ring 312. The number of the locating holes 412 is two, and the two locating holes 412 are relatively arranged on opposite sides of the top of the female seat 41.

[0052] Please refer to Fig. 9The locking module 30 further includes a circuit board 36, which is disposed on the male seat 31. Specifically, the male seat 31 further includes an annular plate 315 and a mounting plate 316. The annular plate 315 is disposed on one end of the housing 311 away from the convex ring 312. The circuit board 36 is disposed in the annular plate 315, and the mounting plate 316 covers one end of the annular plate 315 away from the housing 311. The circuit board 36 is connected to the rotary driver 343 by telecommunication. The circuit board 36 is also used to connect to the remote controller signal, that is, the remote controller remotely sends a signal to the circuit board 36, and the circuit board 36 controls the operation of the actuating assembly 34 according to the signal.

[0053] When the first AGV body 610 needs to be separated from the first working module 620, Fig.10 Taking the left cam block 33 as an example, the lifting drive member 341 drives the movable block 342 to descend. When the movable block 342 descends, it drives the swinging part 332 to descend, and the rotating part 331 rotates clockwise, so that the buckling part 333 rises. In this way, the buckling part 333 disengages from the buckle groove 421 and moves into the gap 313. At this time, the locking module 30 and the first working module 620 are in an unlocked state, and the first AGV body 610 and the first working module 620 can be separated, that is, the first working module 620 can be replaced. When the first AGV body 610 needs to be connected to the first working module 620, the lifting drive member 341 drives the movable block 342 to rise. When the movable block 342 rises, it drives the swinging part 332 to rise, and the rotating part 331 rotates counterclockwise, so that the buckling part 333 falls. In this way, the buckling part 333 moves to the outside of the convex ring 312 and buckles into the buckle groove 421. At this time, the locking module 30 and the first working module 620 are in a locked state, so that the first AGV body 610 and the first working module 620 can be detachably connected. Fig.10 .

[0054] Please refer again Figure 1 and Figure 2 In some embodiments, the CNC machining automatic production line further includes a feeding area 700 and a second AGV 800. The feeding area 700 is located at the upstream end of the conveying area 100. Specifically, the feeding area 100 is located at one end of the conveying area 100, the loading and unloading area 300 and the processing area 200. The space distribution is compact, which effectively reduces the space occupation. The second AGV 800 is arranged in the feeding area 700, and the second AGV 800 is used to transfer the workpiece from the feeding area 700 to the conveying line 400.

[0055] Please refer to Figure 5 and Figure 6The second AGV 800 includes a second AGV body 810 and a second working module 820. The second working module 820 is detachably connected to the second AGV body 810. The second AGV body 810 is used to drive the second working module 820 to walk. The second working module 820 is used to complete the specified work task. The second working module 820 can be a roller module 821 or a traction module 822. By modularizing the functional structure of the second AGV 800, the second working module 820 with different functions can be switched on the second AGV body 810 according to the needs, so as to be able to transfer different types of workpieces, effectively saving costs. It should be noted that the specific connection method between the second working module 820 and the second AGV body 810 is the same as the specific connection method between the first working module 620 and the first AGV body 610, which will not be repeated here.

[0056] Please continue to refer to Figure 1 and Figure 2 Further, the CNC machining automatic production line also includes a fence 900, which encloses the conveying area 100, the loading and unloading area 300 and the processing area 200. The fence 900 is provided with a feed port 910, a discharge port 920 and an inlet and outlet 930. The feed port 910 connects the feed area 100 and the conveying area 100, and the discharge port 920 is arranged at one end of the fence 900 away from the feed port 910. The discharge port 920 connects the conveying area 100 and the outside of the fence 900. One end of the conveying line 400 extends out of the feed port 910, that is, one end of the conveying line 400 extends from the feed port 910 to the conveying area 100. The inlet and outlet 930 connects the feed area 100 and the loading and unloading area 300, so that the operator can directly enter and exit the loading and unloading area 300 from the feed area 100 through the inlet and outlet 930, which brings certain convenience to the operator.

[0057] Furthermore, a partition wall 940 is arranged between the conveying area 100 and the loading and unloading area 300, and a loading port 950 and a unloading port 960 are arranged on the partition wall 940. The loading port 950 and the unloading port 960 are both connected to the conveying area 100 and the loading and unloading area 300, and the loading port 950 is arranged at one end of the partition wall 940 close to the feed port 910, and the unloading port 960 is arranged at one end of the partition wall 940 close to the discharge port 920.

[0058] It can be understood that the second AGV 800 transfers the workpiece to be processed from the feed port 910 to the conveyor line 400. The conveyor line 400 conveys the workpiece from the feed port 910 to the discharge port 920. When the workpiece to be processed passes through the loading port 950, the first AGV 600 grabs the workpiece to be processed from the loading port 950 and transfers it to the CNC machine tool 500, that is, the first AGV 600 loads the workpiece to be processed from the conveyor line 400 to the CNC machine tool 500. After the CNC machine tool 500 completes the processing of the workpiece, the first AGV 600 grabs the processed workpiece from the CNC machine tool 500 and transfers it to the conveyor line 400 from the unloading port 960, that is, the first AGV 600 unloads the workpiece processed on the CNC machine tool 500 to the conveyor line 400. The conveyor line 400 continues to transport the processed workpiece toward the discharge port 920. An external mechanism takes the workpiece processed on the conveyor line 400 away from the discharge port 920 .
