Description

Technical Field

[0001] This utility model relates to the field of industrial robot technology, and in particular to an industrial robot visual positioning anti-deviation device. Background Technology

[0002] Industrial robots are multi-jointed manipulators or multi-degree-of-freedom machines designed for industrial applications. They can perform tasks automatically, relying on their own power and control capabilities to achieve various functions. They can be commanded by humans or operate according to pre-programmed procedures. Modern industrial robots can also act according to principles and guidelines established by artificial intelligence technology, playing a vital role in modern industrial production.

[0003] In modern industrial production, industrial robots are being used more and more widely. Among them, the vision positioning system plays a crucial role as a key part of industrial robots to achieve precise operation. However, existing industrial robots cannot center the grip during the vision positioning process. The robot needs to adjust the gripping position multiple times to try to grasp correctly. This increases the operation time of a single workpiece. Moreover, defective products caused by gripping deviation need to be reprocessed or processed, further wasting time and resources and reducing overall production efficiency.

[0004] To address the aforementioned issues, we have developed an industrial robot visual positioning anti-deviation device. Utility Model Content

[0005] This utility model discloses an industrial robot visual positioning anti-deviation device, which aims to solve the technical problems in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An industrial robot visual positioning anti-deviation device includes a base and an industrial robotic arm. The industrial robotic arm is disposed above the base. The output shaft of the industrial robotic arm is fixedly connected to a U-shaped frame. Two sliding rods are fixedly connected inside the U-shaped frame. Two clamping plates are slidably connected between the outer sides of the two sliding rods. A rack is fixedly connected to one end of each clamping plate on the side closest to each other. A first motor is fixedly connected to one side of the U-shaped frame. The output shaft of the first motor extends into the interior of the U-shaped frame and is fixedly connected to gears. All gears are meshed with the racks.

[0008] By setting a first motor to drive the gear to rotate, the gear meshes with the rack, and the rotation of the gear causes the two clamping plates to slide relative to or away from each other along the sliding rod, thereby realizing the clamping and releasing operation of the object. This enables the industrial robot to stably grasp and transport objects, improving work efficiency. The U-shaped frame provides stable support for the entire clamping structure, and the sliding rod ensures the smoothness of the clamping plate sliding, ensuring the reliability of the clamping process.

[0009] In a preferred embodiment, a support frame is fixedly connected inside the U-shaped frame, and a visual positioning sensor is fixedly connected to the outside of the support frame.

[0010] By installing visual positioning sensors fixed on the support frame, the position information of the object can be obtained in real time. Based on this information, precise positioning can be performed, and the movements of the industrial robotic arm can be adjusted to ensure that the gripper accurately holds the object, effectively preventing the object from shifting and improving the accuracy and precision of positioning.

[0011] In a preferred embodiment, four fixed plates are fixedly connected to the top of the base, and a conveyor belt is arranged between the four fixed plates. The industrial robotic arm is used in conjunction with the conveyor belt. A second motor is fixedly connected to the outer side of one of the fixed plates, and the output shaft of the second motor is fixedly connected to the drive roller of the conveyor belt.

[0012] By setting a second motor to drive the active roller of the conveyor belt to rotate, the conveyor belt can be driven to run. The conveyor belt can transport items into the working range of the industrial robotic arm, realizing continuous material transportation. When the industrial robotic arm is used in conjunction with the conveyor belt, it can realize automated material gripping and handling, improving production efficiency.

[0013] In a preferred embodiment, mounting brackets are fixedly connected to both sides of the bottom of the industrial robotic arm, and the mounting brackets are threadedly connected to the base by mounting screws.

[0014] By setting the industrial robotic arm to be threadedly connected to the base via mounting brackets and mounting screws, the industrial robotic arm can be firmly fixed to the base, ensuring the stability of the industrial robotic arm's operation. At the same time, it is also convenient to disassemble and install when the industrial robotic arm needs to be repaired or replaced.

[0015] In a preferred embodiment, anti-slip pads are fixedly connected to the adjacent sides of both clamping plates.

[0016] By fixing anti-slip pads on the side where the two clamping plates are close together, the anti-slip pads can increase the friction between the clamping plates and the items when clamping them, preventing the items from slipping during the clamping process and further improving the stability of the items being clamped.

[0017] In a preferred embodiment, a controller is fixedly connected to the top of the base, and the industrial robotic arm, the first motor, the visual positioning sensor, and the second motor are all electrically connected to the controller.

[0018] By setting up a controller, the movement of the industrial robotic arm and the first motor can be controlled based on feedback information from the visual positioning sensor, enabling precise grasping and handling of items, improving production efficiency and reducing errors from manual operation.

[0019] In a preferred embodiment, the base is fixedly connected to four support legs at its bottom, and a reinforcing rod is fixedly connected between each pair of support legs.

[0020] By fixing the support legs to the bottom of the base, a stable support is provided for the entire device. The reinforcing rod connects the two corresponding support legs, which enhances the connection strength between the support legs, improves the overall stability of the device, and ensures that the device will not shake or tilt during operation.

[0021] The industrial robot visual positioning anti-deviation device provided by this utility model has the following advantages:

[0022] In this invention, the first motor drives the gear to rotate. Since the gear meshes with the rack, the rotation of the gear causes the two clamping plates to slide relative to or away from each other along the sliding rod, thereby realizing the clamping and releasing operation of the object. This enables the industrial robot to stably grasp and transport objects. After achieving centering clamping, the robot can accurately grasp and place the workpiece without multiple adjustments, saving operation time. Moreover, precise clamping can reduce downtime and readjustment caused by positional deviation, making the production process smoother and more efficient. Compared with traditional devices, it greatly improves the operation quality and efficiency. Attached Figure Description

The gears 8 are all meshed with the rack 6.

[0032] In this embodiment: the first motor 7 drives the gear 8 to rotate.

[0035] In a preferred embodiment, four fixed plates 11 are fixedly connected to the top of the base 1, and a conveyor belt 12 is arranged between the four fixed plates 11. The industrial robotic arm 2 is used in conjunction with the conveyor belt 12. A second motor 13 is fixedly connected to the outer side of one of the fixed plates 11, and the output shaft of the second motor 13 is fixedly connected to the drive roller of the conveyor belt 12.

[0036] In this embodiment, the second motor 13 drives the active roller of the conveyor belt 12 to rotate, thereby driving the conveyor belt 12 to run. The conveyor belt 12 can transport items to the working range of the industrial robotic arm 2, realizing continuous material transport. The industrial robotic arm 2 and the conveyor belt 12 work together to realize automated material gripping and handling, improving production efficiency.

[0037] In a preferred embodiment, mounting brackets 14 are fixedly connected to both sides of the bottom of the industrial robotic arm 2, and the mounting brackets 14 are threadedly connected to the base 1 by mounting screws 15.

[0038] In this embodiment, the industrial robotic arm 2 is threadedly connected to the base 1 via the mounting bracket 14 and mounting screws 15, which allows the industrial robotic arm 2 to be firmly fixed on the base 1, ensuring the stability of the operation of the industrial robotic arm 2. At the same time, it is also convenient to disassemble and install when the industrial robotic arm 2 needs to be repaired or replaced.

[0039] In a preferred embodiment, anti-slip pads 16 are fixedly connected to the sides of the two clamping plates 5 that are close to each other.

[0040] In this embodiment, the anti-slip pad 16 is fixed on the side of the two clamping plates 5 that are close to each other. When clamping an item, the anti-slip pad 16 can increase the friction between the clamping plate 5 and the item, prevent the item from slipping during the clamping process, and further improve the stability of the item clamping.

[0041] In a preferred embodiment, a controller 17 is fixedly connected to the top of the base 1, and the industrial robotic arm 2, the first motor 7, the visual positioning sensor 10, and the second motor 13 are all electrically connected to the controller 17.

[0043] In a preferred embodiment, four support legs 18 are fixedly connected to the bottom of the base 1, and a reinforcing rod 19 is fixedly connected between each pair of support legs 18.

[0045] Working principle: During use, the industrial robotic arm 2 is fixed to the base 1 by the mounting bracket 14 and mounting screws 15. The operator issues a command through the controller 17 to start the second motor 13, which drives the conveyor belt 12 to start running and transport the workpiece to be processed to the work area. The visual positioning sensor 10 collects and analyzes the position, posture and other information of the workpiece, calculates the movement path and angle of the industrial robotic arm 2, and drives the U-shaped frame 3 to move to a suitable position above the workpiece. The output shaft of the first motor 7 drives the gear 8 to rotate. Since the gear 8 is meshed with the rack 6 on the two clamping plates 5, the rotation of the gear 8 causes the two clamping plates 5 to slide towards the center on the sliding rod 4. The anti-slip pads 16 on the two clamping plates 5 contact the workpiece and gradually clamp the workpiece to prevent it from shifting or falling during transportation. After achieving centering clamping, the robot can accurately grasp and place the workpiece without multiple adjustments, saving operation time. Moreover, precise clamping can reduce downtime and readjustment caused by position deviation, making the production process smoother and more efficient. Compared with traditional devices, it greatly improves the operation quality and efficiency.
