In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0064] Such as Figure 1As shown, this embodiment provides a processing production line for shaft workpieces. In the figure, the X direction represents the first horizontal direction, the Y direction represents the second horizontal direction, and the first horizontal direction is perpendicular to the second horizontal direction. The processing production line for shaft workpieces includes a first processing machine tool 10, a second processing machine tool 20, a first carrier car 30, a transfer station 40, a first robotic arm device 80, a main conveying mechanism 50, a second carrier car 60, a plurality of third processing machine tools 70, and a second robotic arm device 90. Among them, the first processing machine tool 10 and the second processing machine tool 20 are arranged opposite to each other along the first horizontal direction (i.e., the X direction), and the first processing machine tool 10 and the second processing machine tool 20 can respectively perform the first processing and the second processing on the workpiece 200. The first carrier car 30 can load the workpiece 200 and transport the workpiece 200 between the first processing machine tool 10 and the second processing machine tool 20. The first carrier car 30 and the transfer station 40 are arranged opposite to each other along the second horizontal direction (i.e., the Y direction), that is, the first processing machine tool 10, the second processing machine tool 20, the first carrier car 30, and the transfer station 40 are arranged in a quadrilateral structure. The first robotic arm device 80 is arranged between the first processing machine tool 10 and the second processing machine tool 20 and can convey the workpiece 200 between the first carrier car 30, the first processing machine tool 10, the second processing machine tool 20, and the transfer station 40. The second carrier car 60 and the transfer station 40 are arranged opposite to each other along the second horizontal direction. The main conveying mechanism 50 extends along the second horizontal direction and is arranged between the transfer station 40 and the second carrier car 60. A plurality of third processing machine tools 70 are respectively arranged on one side or both sides of the main conveying mechanism 50 along the second horizontal direction. The second robotic arm device 90 is arranged on the main conveying mechanism 50, and the main conveying mechanism 50 can drive the second robotic arm device 90 to move along the second horizontal direction so that the second robotic arm device 90 conveys the workpiece 200 between the transfer station 40, the third processing machine tools 70, and the second carrier car 60.

[0065] When the processing production line for shaft workpieces in this embodiment is in use: The first carrier cart 30 can move to other positions to obtain the workpieces 200 to be processed, and then the first carrier cart 30 moves between the first processing machine tool 10 and the second processing machine tool 20. Then, the first robotic arm device 80 can sequentially complete: grasping the workpiece 200 on the first carrier cart 30 and placing it on the first processing machine tool 10 for processing, grasping the workpiece 200 processed by the first processing machine tool 10 and placing it on the second processing machine tool 20 for processing, and grasping the workpiece 200 processed by the second processing machine tool 20 and placing it on the intermediate transfer table 40. The second robotic arm device 90 can complete: grasping the workpiece 200 on the intermediate transfer table 40 and placing it into any one of the third processing machine tools 70 for processing, placing the workpiece 200 processed by the third processing machine tool 70 into another third processing machine tool 70 for continuous processing or placing it into the second carrier cart 60. When a certain number of workpieces 200 are accumulated on the second carrier cart 60, the second carrier cart 60 then transports the workpieces 200 together to other positions.

[0066] In the processing production line for shaft workpieces in this embodiment, the first carrier cart 30, the first processing machine tool 10, the second processing machine tool 20, and the intermediate transfer table 40 are arranged in a quadrilateral structure, enabling the first robotic arm device 80 to complete loading, unloading, and transfer on the first carrier cart 30, the first processing machine tool 10, the second processing machine tool 20, and the intermediate transfer table 40. The main conveyor mechanism 50 is provided to enable the second robotic arm device 90 to move along the second horizontal direction to complete loading, unloading, and operation on the intermediate transfer table 40, the third processing machine tool 70, and the second carrier cart 60. Therefore, the entire production process of the shaft workpieces does not require manual operation and has a high degree of automation. In addition, by providing the intermediate transfer table 40, the actions of the entire production line are divided into two segments, and the first robotic arm device 80 and the second robotic arm device 90 can simultaneously perform loading, unloading, and rotation of the workpiece 200, thereby greatly improving the production efficiency of the shaft workpieces.

[0067] In this embodiment, the first processing machine tool 10 is a numerically controlled lathe, the second processing machine tool 20 is a high-frequency machine, and the third processing machine tool 70 is a numerically controlled grinding machine. The numerically controlled lathe, the high-frequency machine, and the numerically controlled grinding machine can all be any one of the existing technologies and are not limited herein. In other embodiments, the specific types of the first processing machine tool 10, the second processing machine tool 20, and the third processing machine tool 70 can be adjusted according to actual processing requirements and are not limited herein.

[0068] Optionally, as Figure 1As shown in the figure, the processing production line for shaft workpieces includes four third processing machines 70, two of which are arranged along the second horizontal direction and are disposed on one side of the main conveying mechanism 50, and the other two third processing machines 70 are arranged along the second horizontal direction and are disposed on the other side of the main conveying mechanism 50. When the second robotic arm device 90 grabs the workpiece 200 from one third processing machine 70, the workpiece 200 can be placed into another third processing machine 70 for continuous processing according to the actual processing technology, or directly move along the main conveying mechanism 50 to the second carrier car 60 and be placed on the second carrier car 60.

[0069] Preferably, as Figure 2 shown, the first carrier car 30 includes a limit base 32, a car body 31 and a limit support 33. The limit support 33 is fixed on the car body 31, and a V-shaped card slot is arranged on the limit support 33. The workpiece 200 can be clamped in the V-shaped card slot, so as to ensure that the workpiece 200 is stably supported on the car body 31, and the car body 31 can drive the workpiece 200 to move. The limit base 32 is fixed on the ground and is located between the first processing machine 10 and the second processing machine 20. The car body 31 can move to the limit base 32 and be limited inside the limit base 32, so as to ensure the position of the car body 31 and the workpiece 200 thereon is determined, and further ensure that the first robotic arm device 80 can accurately grab the workpiece 200 from the car body 31. Specifically, as Figure 2 shown, the limit base 32 includes a limit frame 321 and a guiding component 322. The limit frame 321 forms a "U"-shaped structure, and the car body 31 can be inserted into the limit frame 321 from the open side of the limit frame 321. The guiding component 322 is arranged on the side of the limit frame 321. Specifically, the guiding component 322 includes a plurality of rollers. When the car body 31 is pushed into the limit frame 321, the rollers rollingly cooperate with the side wall of the car body 31, so that the process of inserting the car body 31 into the limit frame 321 is smoother.

[0070] Preferably, the structures of the first robotic arm device 80 and the second robotic arm device 90 are the same, so as to reduce the design cost of the entire processing production line for shaft workpieces. The following takes the first robotic arm device 80 as an example to describe its structure in detail:

[0071] As Figure 3As shown in the figure, the first robotic arm device 80 includes a base mechanism 81, a robotic arm body 82, and a clamping mechanism 83. Among them, the base mechanism 81 is fixed on the ground and is located between the first processing machine tool 10 and the second processing machine tool 20. The robotic arm body 82 is arranged on the base mechanism 81, and the base mechanism 81 can drive the robotic arm body 82 to rotate around the axis in the vertical direction. The clamping mechanism 83 is connected to the output end of the robotic arm body 82, and the clamping mechanism 83 can clamp at least one workpiece 200. When the first robotic arm device 80 clamps the workpiece 200 from the first carrier cart 30, the base mechanism 81 first drives the robotic arm body 82 to rotate so that the clamping mechanism 83 faces the first carrier cart 30. Then, the robotic arm body 82 drives the clamping mechanism 83 to move to a position where it docks with the workpiece 200 on the first carrier cart 30. Then, the clamping mechanism 83 clamps the workpiece 200. Finally, the base mechanism 81 and the robotic arm body 82 cooperate to drive the clamping mechanism 83 to place the workpiece 200 into the first processing machine tool 10. It can be understood that the process of the first robotic arm device 80 transporting the workpiece 200 in the first processing machine tool 10 to the second processing machine tool 20 and transporting the workpiece 200 in the second processing machine tool 20 to the intermediate transfer station 40 is similar to the above process and will not be elaborated here.

[0072] In this embodiment, the base mechanism 81 includes a base body and a rotation driving source. The robotic arm body 82 is connected to the output end of the rotation driving source, so that the rotation driving source can drive the robotic arm body 82 to rotate around the axis in the vertical direction. Specifically, the rotation driving source can be a motor. The robotic arm body 82 can be any six-axis robotic arm in the prior art, and its specific structure and working principle will not be elaborated here.

[0073] Preferably, as Figure 3 shown, the clamping mechanism 83 includes a support assembly 831 and at least two clamping parts 832. Among them, the support assembly 831 is connected to the output end of the robotic arm body 82, and the clamping parts 832 are connected to the support assembly 831. Each clamping part 832 can act independently to clamp or release the workpiece 200, and the robotic arm body 82 can drive the support assembly 831 to rotate so that any one of the clamping parts 832 can pick up or place the workpiece 200 from a preset position. It should be noted that the preset position can be the position where the workpiece 200 is fixed on the first carrier cart 30, the first processing machine tool 10, or the second processing machine tool 20.

[0074] Taking the loading and unloading of the clamping mechanism 83 on the first processing machine tool 10 as an example, the operation of the clamping mechanism 83 will be described as follows: Among the two clamping parts 832 of the clamping mechanism 83, one clamping part 832 clamps the workpiece 200 clamped from the first carrier cart 30, and the other clamping part 832 is in an unloaded state. When the clamping mechanism 83 moves to the first processing machine tool 10, first make the unloaded clamping part 832 face the workpiece 200 in the first processing machine tool 10 and grab the workpiece 200, and then the robot arm body 82 drives the clamping mechanism 83 to rotate, so that the clamping part 832 that originally clamped the workpiece 200 places the workpiece 200 into the first processing machine tool 10. That is to say, by setting the clamping mechanism 83 to include two clamping parts 832, the first robot arm device 80 can complete the actions of unloading the processed workpiece 200 and loading the workpiece 200 to be processed together, thereby greatly improving the working efficiency of the first robot arm device 80 and also improving the working efficiency of the entire processing production line of shaft workpieces.

[0075] In this embodiment, as Figure 4 shown, the support assembly 831 includes a connecting plate 8311 and two connecting seats 8312. Among them, the connecting plate 8311 is connected to the output end of the robot arm body 82, and the robot arm body 82 can drive the connecting plate 8311 to rotate. The two connecting seats 8312 are respectively connected to the connecting plate 8311, and each clamping part 832 is correspondingly connected to one connecting seat 8312.

[0076] Preferably, as Figure 4 and Figure 5 shown, the clamping part 832 includes a fixed clamping assembly 8321, two movable clamping assemblies 8322 and a clamping drive source 8323. Among them, the fixed clamping assembly 8321 is connected to the support assembly 831, the two movable clamping assemblies 8322 are respectively movably connected to the support assembly 831, and the clamping drive source 8323 is connected to the support assembly 831. The clamping drive source 8323 can drive the two movable clamping assemblies 8322 to approach each other and drive the movable clamping assembly 8322 to approach the fixed clamping assembly 8321 to clamp the workpiece 200. One fixed clamping assembly 8321 and two movable clamping assemblies 8322 can clamp the surface of the shaft workpiece 200 from at least three positions, so as to more conveniently and reliably clamp workpieces 200 with different shaft diameters.

[0077] Preferably, as Figure 5As shown, the fixed clamping assembly 8321 includes a fixing member 83211 and two first pressing members 83212. The fixing member 83211 is connected to the support assembly 831, the two first pressing members 83212 are connected to the fixing member 83211, and the pressing surfaces of the two first pressing members 83212 are arranged at an angle. The movable clamping assembly 8322 includes a movable member 83221 and a second pressing member 83222. The movable member 83221 is movably connected to the support assembly 831, the second pressing member 83222 is connected to the movable member 83221, and the pressing surfaces of the two second pressing members 83222 are arranged at an angle. The two first pressing members 83212 arranged at an angle and the two second pressing members 83222 arranged at an angle can respectively clamp the workpiece 200 from four circumferential positions of the shaft-like workpiece 200, thereby further improving the reliability of the clamping of the workpiece 200 by the clamping portion 832.

[0078] Furthermore, the first pressing member 83212 and the second pressing member 83222 are made of a flexible material, so as to prevent the surface of the workpiece 200 from being damaged due to the too tight clamping force of the clamping portion 832, thereby improving the yield rate of the workpiece 200. Specifically, the first pressing member 83212 and the second pressing member 83222 can be made of rubber material.

[0079] In this embodiment, as Figure 5 shown, both the clamping driving source 8323 and the fixed clamping assembly 8321 are fixedly connected to the corresponding connecting seat 8312, and the movable clamping assembly 8322 is movably connected to the connecting seat 8312. Specifically, the fixing member 83211 is fixedly connected to the connecting seat 8312, and the movable member 83221 is movably connected to the connecting seat 8312.

[0080] Preferably, as Figure 5 shown, the first end of the movable clamping assembly 8322 (i.e., the end of the movable member 83221 connected with the second pressing member 83222) is used to clamp the workpiece 200, and the middle part of the movable clamping assembly 8322 (i.e., the middle part of the movable member 83221) is hinged to the support assembly 831. The clamping portion 832 further includes two connecting rods 8324. One end of each connecting rod 8324 is hinged to the output end of the clamping driving source 8323, and the other end is hinged to the second end of the movable clamping assembly 8322. When the clamping driving source 8323 outputs a linear motion, the two movable clamping assemblies 8322 rotate around the hinge axis between them and the support assembly 831, so that the first ends of the two movable clamping assemblies 8322 approach each other and also approach the fixed clamping assembly 8321 at the same time. That is, the clamping portion 832 of this embodiment realizes the driving of the two movable clamping assemblies 8322 in two directions of approaching each other and approaching the fixed clamping assembly 8321 through one clamping driving source 8323, with a simple structure and low cost. In this embodiment, the clamping driving source 8323 can be a linear cylinder.

[0081] In this embodiment, the structure of the second robotic arm device 90 is exactly the same as that of the first robotic arm device 80, and will not be described in detail here. As Figure 6 shown, the difference is that the base mechanism 81 of the second robotic arm device 90 is arranged on the main conveying mechanism 50, so that the main conveying mechanism 50 can drive the entire second robotic arm device 90 to move along the second horizontal direction.

[0082] As Figure 7 shown, the main conveying mechanism 50 includes a support base 51, a first transmission member 52, a second transmission member 54 and a conveying drive source 53. The support base 51 is fixed on the ground, the base mechanism 81 of the second robotic arm device 90 is slidably connected to the support base 51, the first transmission member 52 is arranged on the support base 51 and extends along the second horizontal direction, the conveying drive source 53 is connected to the second robotic arm device 90, the second transmission member 54 is connected to the output end of the conveying drive source 53, the second transmission member 54 is in transmission cooperation with the first transmission member 52, and the conveying drive source 53 can drive the second transmission member 54 to rotate, so that the second transmission member 54 and the entire second robotic arm device 90 move along the second horizontal direction together. In this embodiment, the conveying drive source 53 is a motor, the motor is connected to the base mechanism 81 of the second robotic arm device 90, and the output shaft of the motor passes through the base mechanism 81 to be located below the base mechanism 81. The first transmission member 52 is a rack, the second transmission member 54 is a gear, when the conveying drive source 53 drives the gear to rotate, the gear moves along the rack, and then the second robotic arm device 90 moves. On the one hand, the transmission direction of the gear and the rack can meet faster movement. On the other hand, when the conveying distance is long, the rack can be spliced by multiple sections, which is more convenient to use.

[0083] Preferably, as Figure 7 shown, the main conveying mechanism 50 further includes a guide rail 55 and a slider 56. The guide rail 55 is connected to the support base 51 and extends along the second horizontal direction. The slider 56 is connected to the base mechanism 81 of the second robotic arm device 90 and is slidably matched with the guide rail 55. By setting the guide rail 55 and the slider 56, the movement direction of the second robotic arm device 90 can be accurately guided, and then it is ensured that the second robotic arm device 90 accurately grabs the workpieces 200 on the intermediate transfer table 40 and the third processing machine tool 70.

[0084] In some usage scenarios, the second robotic arm device 90 needs to directly place the workpiece 200 in each third processing machine tool 70 into the second carrier cart 60. Every time the second robotic arm device 90 grabs a workpiece 200 from the third processing machine tool 70, it needs to move towards the second carrier cart 60 once, resulting in a low working efficiency of the second robotic arm device 90. In order to further improve the working efficiency of the shaft workpiece processing production line, as Figure 1As shown in the figure, the shaft workpiece processing production line further includes an auxiliary conveying mechanism 100. The auxiliary conveying mechanism 100 extends along the second horizontal direction and is arranged on one side of the main conveying mechanism 50. The auxiliary conveying mechanism 100 can receive the workpiece 200 on the second robotic arm device 90 and convey the workpiece 200 to one end close to the second carrier trolley 60.

[0085] After the second robotic arm device 90 takes out the workpiece 200 in one of the third processing machines 70, the workpiece 200 can be first placed on the auxiliary conveying mechanism 100. The second robotic arm device 90 can continue to execute grasping the workpiece 200 from the transfer table 40 or grasping the workpiece 200 from other third processing machines 70. During this process, the auxiliary conveying mechanism 100 cooperates with the second robotic arm device 90 to move in the second horizontal direction to ensure that each workpiece 200 grasped by the second robotic arm device 90 can be received. After the second robotic arm device 90 grasps all the workpieces 200 in all the third processing machines 70, the second robotic arm device 90 and the auxiliary conveying mechanism 100 move together to one end of the second carrier trolley 60. Finally, the second robotic arm device 90 places the last workpiece 200 it grasped and all the workpieces 200 on the auxiliary conveying mechanism 100 onto the second carrier trolley 60 one by one. By providing the auxiliary conveying mechanism 100, the number of reciprocating movements of the second robotic arm device 90 along the main conveying mechanism 50 can be reduced, thereby improving the working efficiency of the second robotic arm device 90 and further improving the working efficiency of the entire shaft workpiece processing production line.

[0086] Specifically, as Figure 1 shown, the auxiliary conveying mechanism 100 includes a bearing assembly 101 and a conveyor belt assembly 102. The conveyor belt assembly 102 extends along the second horizontal direction and is arranged on one side of the main conveying mechanism 50. The bearing assembly 101 can bear and limit a plurality of workpieces 200. The conveyor belt assembly 102 can drive the bearing assembly 101 to reciprocate along the second horizontal direction, so that it can move along the second horizontal direction together with the second robotic arm device 90, and further can receive each workpiece 200 grasped by the second robotic arm device 90. Specifically, the bearing assembly 101 includes a bottom plate and a support member. The bottom plate is connected to the conveyor belt assembly 102. The support member is arranged on the bottom plate and has a V-shaped groove. The workpiece 200 can be stuck in the V-shaped groove, so that the support member can reliably limit the workpiece 200.

[0087] In this embodiment, the structure of the second carrier trolley 60 is the same as that of the first carrier trolley 30, and will not be described in detail here.

For those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation manners and application scopes.
