Description

[0002] A sorting robot is a robot equipped with sensors, objective lenses and electronic optical systems. It can quickly sort goods. Currently, sorting robots used for parts usually sort parts through the adsorption force of suction cups, and the adsorption force of suction cups depends on the speed of the exhaust fan.

However, during the parts sorting process, the exhaust fan needs to be exhausted at all times. However, long-term operation of the exhaust fan will affect the speed of the exhaust fan, which will cause the adsorption weight of the parts to gradually decrease and affect the accuracy of parts sorting.

When the L-shaped blocking block coincides with the connecting groove, the output end of the third drive motor will be blocked from rotating. When the L-shaped blocking block is separated from the connecting groove, the rotation of the output end of the third drive motor will drive the second circular connecting block to rotate.

[0013] Preferably, a method for using a parts sorting robot comprises the following steps:

[0014] S1. First, the parts that need to be sorted are placed on the upper end surface of the first conveyor belt according to the caliber of the parts grasped by each mechanical claw assembly, and then the first drive motor is started to drive the first conveyor belt to rotate, thereby driving the parts to move. When the parts move to the middle part of the first correction plate and the second correction plate, when the caliber of the parts is larger than the caliber of the space formed by the first correction plate and the second correction plate, the second return spring and the third return spring are contracted, and then the first correction plate is rotated around the first circular rotating rod, and the second correction plate is driven to rotate around the second circular rotating rod, so as to correct the parts. Then, when the first correction plate and the second correction plate form a funnel shape and move to the middle position of the mechanical claw, the first drive motor is stopped, and the parts stop moving forward.

[0015] S2. When the part moves to the middle part of the mechanical claw, the third driving motor at one end of the guide assembly is started to rotate and the second conveyor belt is started to rotate, thereby driving the second circular connecting block to rotate, and then driving the rotating rod to rotate. As the rotating rod rotates, the first rotating belts in the plurality of mechanical claw assemblies are driven to rotate, thereby driving the bidirectional threaded rod to rotate, and then driving the mechanical claw to move along the slide groove toward the middle part of the bidirectional threaded rod. When the upper ends of the mechanical claws are in contact, the part is clamped;

[0016] S3. After the mechanical claw clamps the part, starting the second drive motor will drive the trigger block to rotate and the circular rotating block to rotate. As the circular rotating block rotates, the mechanical arm will move along the arc-shaped guide block, thereby driving the mechanical claw assembly to move and driving the rotating rod to move along the arc-shaped slide slot until the mechanical arm coincides with the first rectangular slide slot opened by the first rectangular support block at the other end of the arc-shaped guide block. During the coincidence of the mechanical arm and the first rectangular slide slot, a thrust will be generated on the L-shaped blocking block, thereby driving the reset spring to perform a contraction operation;

[0017] S4. When the robotic arm coincides with the first rectangular groove opened in the first rectangular support block at the other end of the arc-shaped guide block, the L-shaped blocking block is separated from the connecting groove, and the parts clamped by the robotic claw are moved to the upper end surface of the second conveyor belt, and the rotating rod is connected to the second connecting groove. At this time, the third drive motor connected to the other end of the guide assembly rotates counterclockwise, so that the robotic claw moves toward the two ends of the two-way threaded rod, thereby releasing the fixation of the parts, and then allowing the second conveyor belt to drive the parts to move, and then starting the second drive motor to rotate, thereby driving the robotic arm to return to its original position, so that the trigger block coincides with the trigger groove opened at one end of the controller, and then starting the first drive motor and driving the first conveyor belt to continue rotating, and performing the next step of parts sorting operation.

[0018] Compared with the prior art, the advantages of the present invention are:

[0019] 1. In the present invention, the parts are clamped by starting the third drive motor connected to one end of the guide assembly, and then the second drive motor is started to drive the manipulator assembly to move along the arc-shaped guide block. When the manipulator arm coincides with the first rectangular slide groove opened at the other end of the guide assembly, the L-shaped blocking block is separated from the connecting groove, and the third rectangular connecting block connected to one end of the rotating rod is coincident with the second connecting groove. At this time, the third drive motor connected to the other end of the guide assembly is started to rotate counterclockwise to release the clamping of the parts. In this way, the guide assembly and the manipulator assembly can produce a linkage effect. At the same time, when the L-shaped blocking block is separated from the connecting groove, the mechanical claw will clamp and release the clamping operation on the parts, so that the mechanical claw can operate intermittently, thereby improving the service life of the sorting robot and improving the clamping accuracy of the sorting robot.

[0020] 2. In the present invention, the initial spacing of the mechanical claws is equal, and then the third drive motor connected to one end of the guide assembly is started to drive the rotating rod to rotate, thereby driving the mechanical claws to move along the middle part of the bidirectional threaded rod. When the upper ends of the mechanical claws are in contact, the spacing of the mechanical claws in several mechanical claw assemblies will gradually decrease, and the difference between the initial spacing of the mechanical claws and the final spacing of the mechanical claws is equal to the range of the part clamping aperture, thereby increasing the diversity of part sorting and further improving the sorting efficiency of the sorting robot.

[0021] 3. In the present invention, when the part moves to the middle part of the first correction plate and the second correction plate, when the diameter of the part is larger than the diameter of the space formed by the first correction plate and the second correction plate, the second return spring and the third return spring will be contracted, so that the first correction plate can rotate around the first circular rotating rod, and the second correction plate can be driven to rotate around the second circular rotating rod, so as to perform a correction operation on the part. In this way, the part is corrected during the movement and the part is moved to the middle part of the mechanical claw, which provides the prerequisite for the mechanical claw assembly to clamp the part and improves the sorting efficiency of the sorting robot.

[0035] See also Figure 4 The driving component 305 includes a third driving motor 306, the output end of the third driving motor 306 is provided with a connecting groove 307, and the output end of the third driving motor 306 is connected to a second circular connecting block 308, the second circular connecting block 308 is provided with a second connecting groove 309 at one end facing the first conveyor belt 1, one end of the third driving motor 306 is connected to an L-shaped blocking block 310, the end of the L-shaped blocking block 310 away from the third driving motor 306 is connected to a return spring 311, and the second circular connecting block 308 is provided with an entrance at one end facing the rotating rod 406.

[0036] The connecting groove 307 is matched with the L-shaped blocking block 310, and the second connecting groove 309 is matched with the rotating rod 406. When the L-shaped blocking block 310 coincides with the connecting groove 307, the output end of the third driving motor 306 is blocked from rotating.

[0038] Specifically, the third driving motor 306 connected to one end of the guide assembly 3 is started to drive the rotating rod 406 to rotate, thereby driving the mechanical claw 412 to move along the middle part of the bidirectional threaded rod 411, and then clamping the parts, and then starting the second driving motor 401 to drive the manipulator assembly 4 to move along the arc-shaped guide block 301.

[0040] Specifically, when the part moves to the middle part of the first correction plate 903 and the second correction plate 905, when the diameter of the part is larger than the diameter of the space formed by the first correction plate 903 and the second correction plate 905, the second return spring 902 and the third return spring 907 will be contracted, so that the first correction plate 903 can rotate around the first circular rotating rod 904, and the second correction plate 905 can be driven to rotate around the second circular rotating rod 906, so as to correct the part.

[0041] A method for using a parts sorting robot comprises the following steps:

[0042] S1. First, the parts that need to be sorted are placed on the upper end surface of the first conveyor belt 1 according to the caliber of the parts grasped by each mechanical claw assembly 408, and then the first drive motor 8 is started to drive the first conveyor belt 1 to rotate, thereby driving the parts to move. When the parts move to the middle part of the first correction plate 903 and the second correction plate 905, when the caliber of the parts is larger than the spatial caliber formed by the first correction plate 903 and the second correction plate 905, the second return spring 902 and the third return spring 907 will be contracted, and then the first correction plate 903 will rotate around the first circular rotating rod 904, and the second correction plate 905 will be driven to rotate around the second circular rotating rod 906, so as to correct the parts. Then, when the first correction plate 903 and the second correction plate 905 form a funnel shape and move to the middle position of the mechanical claw 412, the first drive motor 8 is stopped, and the parts stop moving forward;

[0043] S2. When the part moves to the middle part of the mechanical claw 412, the third driving motor 306 at one end of the guide assembly 3 is started to rotate and the second conveyor belt 6 is started to rotate, thereby driving the second circular connecting block 308 to rotate, and then driving the rotating rod 406 to rotate. As the rotating rod 406 rotates, the first rotating belts 410 in the mechanical claw assemblies 408 are driven to rotate, thereby driving the bidirectional threaded rod 411 to rotate, and then driving the mechanical claw 412 to move along the slide groove toward the middle part of the bidirectional threaded rod 411. When the upper ends of the mechanical claws 412 are in contact, the parts are clamped;

[0044] S3. After the mechanical claw 412 clamps the part, starting the second drive motor 401 will drive the trigger block 402 to rotate and the circular rotating block 403 to rotate. As the circular rotating block 403 rotates, the mechanical arm 405 will move along the arc-shaped guide block 301, thereby driving the mechanical claw assembly 408 to move and driving the rotating rod 406 to move along the arc-shaped slide groove 302, until the mechanical arm 405 coincides with the first rectangular slide groove 304 formed by the first rectangular support block 303 at the other end of the arc-shaped guide block 301. During the coincidence of the mechanical arm 405 and the first rectangular slide groove 304, a thrust will be generated on the L-shaped blocking block 310, thereby driving the reset spring 311 to retract.

[0045] S4. When the robot arm 405 coincides with the first rectangular slide groove 304 opened in the first rectangular support block 303 at the other end of the arc-shaped guide block 301, the L-shaped blocking block 310 is separated from the connecting groove 307, and the parts clamped by the mechanical claw 412 are moved to the upper end surface of the second conveyor belt 6, and the rotating rod 406 is connected to the second connecting groove 309. At this time, the third driving motor 306 connected to the other end of the guide assembly 3 is rotated counterclockwise, so that the mechanical claw 412 moves toward the two ends of the two-way threaded rod 411, thereby releasing the fixation of the parts, and then allowing the second conveyor belt 6 to drive the parts to move, and then start the second driving motor 401 to rotate, thereby driving the robot arm 405 to return to its original position, so that the trigger block 402 coincides with the trigger groove opened at one end of the controller 7, and then starts the first driving motor 8 and drives the first conveyor belt 1 to continue rotating, and performs the next step of parts sorting operation.

[0046] Specifically, the initial spacing of the mechanical claws 412 is equal, and then the third drive motor 306 connected to one end of the guide assembly 3 is started to drive the rotating rod 406 to rotate, thereby driving the mechanical claws 412 to move along the middle part of the bidirectional threaded rod 411. When the upper ends of the mechanical claws 412 are in contact, the spacing of the mechanical claws 412 in several mechanical claw assemblies 408 will gradually decrease, and the difference between the initial spacing of the mechanical claws 412 and the final spacing of the mechanical claws 412 is equal to the range of the part clamping diameter, thereby increasing the diversity of part sorting and further improving the sorting efficiency of the sorting robot.

A parts sorting robot according to claim 5, characterized in that: The correction component (9) comprises a fifth rectangular connecting block (901), one end of the fifth rectangular connecting block (901) away from the second rectangular connecting block (404) is connected to a second return spring (902), one end of the second return spring (902) away from the second rectangular connecting block (404) is connected to a first correction plate (903), a front end of the first correction plate (903) is connected to a first circular rotating rod (904), and one end of the first correction plate (903) away from the second return spring (902) is connected to a second correction plate (905), a front end of the second correction plate (905) is connected to a second circular rotating rod (906), and one end of the second correction plate (905) away from the first correction plate (903) is connected to a third return spring (907), and one end of the third return spring (907) away from the second correction plate (905) is connected to a sixth rectangular connecting block (908).

7. A method for using a parts sorting robot, according to the parts sorting robot according to claim 6, characterized in that: The following steps are involved: S1. First, the parts to be sorted are placed on the upper end surface of the first conveyor belt (1) according to the diameter of the parts grasped by each mechanical claw assembly (408), and then the first drive motor (8) is started to drive the first conveyor belt (1) to rotate, thereby driving the parts to move. When the parts move to the middle part of the first correction plate (903) and the second correction plate (905), when the diameter of the parts is larger than the diameter of the space formed by the first correction plate (903) and the second correction plate (905), the second correction plate (905) will be moved to the middle part of the first correction plate (903) and the second correction plate (905). The positioning spring (902) and the third return spring (907) perform a contraction operation, thereby causing the first correction plate (903) to rotate around the first circular rotating rod (904), and driving the second correction plate (905) to rotate around the second circular rotating rod (906), thereby performing a correction operation on the part, and then when the first correction plate (903) and the second correction plate (905) form a funnel shape and move to the middle position of the mechanical claw (412), the first drive motor (8) is stopped, and the part stops moving forward; S2. When the part moves to the middle part of the mechanical claw (412), the third driving motor (306) at one end of the guide assembly (3) is started to rotate and the second conveyor belt (6) is started to rotate, thereby driving the second circular connecting block (308) to rotate, and then driving the rotating rod (406) to rotate. As the rotating rod (406) rotates, the first rotating belts (410) in the plurality of mechanical claw assemblies (408) are driven to rotate, thereby driving the bidirectional threaded rod (411) to rotate, and then driving the mechanical claw (412) to move along the slide groove toward the middle part of the bidirectional threaded rod (411). When the upper ends of the mechanical claws (412) are in contact, the part is clamped; S3. After the mechanical claw (412) clamps the part, starting the second drive motor (401) will drive the trigger block (402) to rotate and the circular rotating block (403) to rotate. As the circular rotating block (403) rotates, the mechanical arm (405) will be driven to move along the arc-shaped guide block (301), thereby driving the mechanical claw assembly (408) to move and driving the rotating rod (406) to move along the arc-shaped slide groove (302) until the mechanical arm (405) and the first rectangular slide groove (304) formed on the first rectangular support block (303) at the other end of the arc-shaped guide block (301) overlap. During the overlap of the mechanical arm (405) and the first rectangular slide groove (304), a thrust is generated on the L-shaped blocking block (310), thereby driving the return spring (311) to perform a contraction operation; S4. When the mechanical arm (405) overlaps with the first rectangular slot (304) formed on the first rectangular support block (303) at the other end of the arc-shaped guide block (301), the L-shaped blocking block (310) is separated from the connecting groove (307), and the part held by the mechanical claw (412) is moved to the upper end surface of the second conveyor belt (6), and the rotating rod (406) is connected to the second connecting groove (309). At this time, the third driving motor (306) connected to the other end of the guide assembly (3) is reversely rotated. The clockwise rotation causes the mechanical claw (412) to move toward the two ends of the bidirectional threaded rod (411), thereby releasing the fixation of the parts, and then allowing the second conveyor belt (6) to drive the parts to move, and then starting the second drive motor (401) to rotate, thereby driving the mechanical arm (405) to return to its original position, so that the trigger block (402) and the trigger groove opened at one end of the controller (7) coincide, and then starting the first drive motor (8) and driving the first conveyor belt (1) to continue rotating, and then performing the next step of the parts sorting operation.
