Description

Technical Field

[0001] This utility model relates to the field of mechanical processing equipment technology, and in particular to an anti-deviation component for a robot bending workstation. Background Technology

[0002] In the field of machining equipment technology, robotic bending workstations have become the core equipment for bending plate-type workpieces due to their high degree of automation and outstanding processing efficiency. Their core technical goal is to ensure the stable and controllable dimensional and angular accuracy of the workpiece after bending, so as to adapt to the needs of subsequent assembly and actual use.

[0003] Chinese patent publication CN110722070B discloses a robotic bending workstation, including a raw material area, a finished product area, a control component, a bending machine, a robot, a vision recognition device for identifying the shape and size of parts to be processed in the raw material area, and a suction fixture for holding the parts. The vision recognition device and the suction fixture are installed at the output end of the robot. The vision recognition device includes a CCD camera and a photoelectric positioning switch for cooperating with the CCD camera to identify the size of the parts. The vision recognition device sends the recognition data to the control component, which retrieves the processing program based on the received recognition data and controls the bending machine, robot, and suction component to process the parts. This robotic bending workstation can identify the shape and size of the parts to be processed and automatically retrieve different processing programs, reducing manual intervention and improving work efficiency.

[0004] However, the aforementioned patent documents lack the effect of adaptive offset and cannot guarantee that the plate will not shift during the bending process. Therefore, we propose an anti-offset component for a robotic bending workstation to solve the above problems. Utility Model Content

[0005] The main objective of this invention is to provide an anti-deviation component for a robot bending workstation, which can effectively solve the problems mentioned above.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] An anti-deviation component for a robot bending workstation includes a mounting component, a deviation component mounted at the rear of the mounting component, a clamping component mounted on the outer surface of the deviation component, a transmission component mounted inside each of the four clamping components, and a drive component mounted at the front of the mounting component.

[0008] Preferably, the mounting assembly includes a mounting base, with two mounting plates 1 mounted at both the front and rear ends of the mounting base, and mounting plates 2 mounted at the right ends of the two mounting plates 1 located on the right side.

[0009] Preferably, the offset assembly includes a motor, which is mounted on the rear end of the mounting plate 2 located at the front. The two mounting plates 1 located on the same side have threaded rods mounted on their adjacent ends. The right ends of the two threaded rods are each mounted with a pulley 1 via a shaft. The outer surfaces of the two pulleys 1 are each mounted with a belt 1.

[0010] Preferably, the clamping assembly includes four sliding shells, two of which are located on the same side are mounted on the outer surface of the threaded rod located in the same part, a mounting shell is mounted on the upper end of each of the four sliding shells, a threaded column is mounted in the inner cavity of each of the four mounting shells, a clamping plate is mounted on the outer surface of each of the four threaded columns, and a limit plate is mounted on the end of each of the four clamping plates away from the mounting base.

[0011] Preferably, the transmission assembly includes eight pulleys 2. Two pulleys 2 located in the same part are installed inside the sliding housing located in the same part. The outer surfaces of the two pulleys 2 located in the same part are jointly mounted with belt 2. The upper ends of the four pulleys 2 far from the center are all mounted with bevel gear 1. The outer surfaces of the four bevel gear 1 are all mounted with bevel gear 2. The inner surfaces of the four bevel gear 2 are all mounted with four locking blocks.

[0012] Preferably, the drive assembly includes a second motor, which is mounted on the front end of the second mounting plate located at the rear. The two mounting plates on the same side are each mounted with a mating rod at their close ends. The right ends of the two mating rods are each mounted with a pulley three via a shaft. The outer surfaces of the two pulley three are each mounted with a belt three.

[0013] Preferably, the output end of the motor is connected to the right end of the threaded rod located at the front via a coupling, and both pulleys are mounted on the right end of the mounting base.

[0014] Preferably, the output end of the second motor is connected to the right end of the mating rod located at the rear via a coupling, both pulleys are mounted on the right end of the mounting base, and the outer surface of both mating rods has four sliding grooves.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. This device, through its designed offset and clamping components, can achieve the effect of clamping and fixing the plate. The core requirement of robot bending is to achieve precise control of dimensions and angles. Plate offset is the main cause of precision failure. The clamping and fixing function can eliminate this problem at its source, eliminate dimensional errors, and after clamping, the plate is rigidly positioned and its relative position with the bending mold and robot gripper is fixed. This avoids the deviation of key dimensions such as bending edge length and relative distance of hole positions caused by plate offset. At the same time, clamping and fixing can ensure that the plate fits the mold in the same position every time, improve the pass rate of batch processing angles, reduce secondary corrections, and eliminate the need to correct offset defects by manual grinding and pressure after bending. It can directly achieve the standard in one process and reduce the cost of subsequent processes.

[0017] 2. This device can achieve anti-offset compensation through its designed transmission and drive components. After the plate is bent, there will inevitably be material springback. Clamping alone cannot eliminate the angular offset caused by this physical characteristic. The anti-offset compensation component can automatically start the motor to make the clamping component and transmission component slide as a whole through real-time angle detection and robot path correction, thereby offsetting the positioning reference error and avoiding the need for immediate clamping and fixing due to accumulated deviation, which would lead to subsequent bending deviation.

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] Example 1, as Figure 1 - Figure 6 As shown, an anti-offset component for a robot bending workstation includes a mounting component 1, an offset component 2 mounted at the rear of the mounting component 1, a clamping component 3 mounted on the outer surface of the offset component 2, a transmission component 4 mounted inside each of the four clamping components 3, and a drive component 5 mounted at the front of the mounting component 1.

[0027] When implementing this solution, the operator first installs the device in the bending workstation system. Then, when the plate needs to be bent, the robot moves the plate between the clamping components 3. The system then activates the drive component 5, which drives the transmission component 4 and the clamping component 3 to slide and clamp the plate, thus initially preventing the plate from shifting during bending.

[0028] During the subsequent bending process, the robot monitors the bending process. When the plate is about to shift, the robot system drives the offset component 2 to rotate. The offset component 2 then moves the clamping component 3, causing the clamping component 3 to move in the opposite direction of the plate's impending shift. This achieves the effect of compensating for the shift. In this process, not only is force used to clamp the plate, but also skill and feedback are employed to reduce the problem of the plate shifting during the bending process.

[0029] Specifically, in order to clamp and fix the plates, such as Figure 2 As shown, in this solution, the mounting component 1 includes a mounting base 11. Two mounting plates 12 are mounted on the front and rear ends of the mounting base 11, and mounting plates 13 are mounted on the right ends of the two mounting plates 12 located on the right side.

[0030] For further details, please refer to [link / reference]. Figure 3 and Figure 5The clamping assembly 3 includes four sliding shells 31. Two sliding shells 31 located on the same side are mounted on the outer surface of the threaded rod 22 located in the same part. Mounting shells 32 are mounted on the upper end of each of the four sliding shells 31. Threaded posts 33 are mounted inside the cavities of each of the four mounting shells 32. Clamping plates 34 are mounted on the outer surfaces of each of the four threaded posts 33. Limiting plates 35 are mounted on the ends of the four clamping plates 34 away from the mounting base 11.

[0031] For further details, please refer to [link / reference]. Figure 5 and Figure 6 The transmission assembly 4 includes eight pulleys 41. Two pulleys 41 located in the same part are installed inside the sliding housing 31 located in the same part. The outer surfaces of the two pulleys 41 located in the same part are jointly mounted with belts 42. The upper ends of the four pulleys 41 far from the center are all mounted with bevel gears 43. The outer surfaces of the four bevel gears 43 are all mounted with bevel gears 44. The inner surfaces of the four bevel gears 44 are all mounted with four locking blocks 45.

[0032] For further details, please refer to [link / reference]. Figure 4 The drive assembly 5 includes a second motor 51, which is mounted on the front end of a second mounting plate 13 located at the rear. Two mounting plates 12 on the same side are each mounted with a mating rod 52 at their close ends. The right ends of the two mating rods 52 are each mounted with a pulley 53 via a shaft. The outer surfaces of the two pulleys 53 are each mounted with a belt 54.

[0033] For further details, please refer to [link / reference]. Figure 4 The output end of motor 2 51 is connected to the right end of the mating rod 52 located at the rear via a coupling. Both pulleys 3 53 are installed on the right end of the mounting base 11. The outer surface of both mating rods 52 has four sliding grooves.

[0034] When implementing this solution, the operator first installs the device in the bending workstation system. Then, when the plate needs to be bent, the robot moves the plate between the clamping plate 34 and the sliding shell 31. The system then starts motor 51, which drives the mating rod 52, pulley 53, belt 54, locking block 45, bevel gear 44, bevel gear 43, belt 42, pulley 41, and threaded post 33 to rotate. As a result, the clamping plate 34 moves the limiting plate 35, clamping the plate and fixing it in place, thus initially preventing the plate from shifting during bending.

[0035] Example 2, which can achieve anti-offset compensation based on Example 1.

[0036] Specifically, in order to achieve anti-offset compensation, such as Figure 2 and Figure 3As shown, in this scheme, the offset component 2 includes a motor 21, which is installed at the rear end of the mounting plate 13 located at the front. The two mounting plates 12 located on the same side are both fitted with threaded rods 22 at their close ends. The right ends of the two threaded rods 22 are fitted with pulleys 23 via shafts. The outer surfaces of the two pulleys 23 are fitted with belts 24.

[0037] For further details, please refer to [link / reference]. Figure 2 and Figure 3 The output end of motor 21 is connected to the right end of threaded rod 22 located at the front via a coupling, and both pulleys 23 are mounted on the right end of mounting base 11.

[0038] During the implementation of this solution, the robot monitors the bending process during the subsequent bending of the plate. When the plate is about to deviate, the robot system drives motor 21 to start, which in turn drives threaded rod 22, pulley 23 and belt 24 to rotate. As a result, threaded rod 22 causes sliding shell 31, mounting shell 32, threaded column 33, clamping plate 34 and limiting plate 35 to move, so that sliding shell 31 moves in the opposite direction of the plate's impending deviation. This achieves the effect of compensating for the deviation when clamping plate 34 clamps the plate. In this process, not only is force used to clamp the plate, but also skill and feedback are used to reduce the problem of plate deviation during bending.

[0039] The device requires the installation of various sensors, which are existing technologies: laser displacement sensor (model: Keyence LK-G series) and pressure sensor (model: HBM P3MB); while the monitor for real-time monitoring of the bending process is an existing technology: Tube Qualify.

[0040] In summary, the implementation process of this utility model is as follows:

[0041] The operator first installs the device in the bending workstation system. Then, when the plate needs to be bent, the robot moves the plate between the clamping plate 34 and the sliding shell 31. The system then starts motor 51, which drives the mating rod 52, pulley 53, belt 54, locking block 45, bevel gear 44, bevel gear 43, belt 42, pulley 41 and threaded column 33 to rotate. As a result, the clamping plate 34 moves the limiting plate 35 to clamp the plate, thus fixing the plate and initially preventing the plate from shifting during bending.

[0042] During the subsequent bending process, the robot monitors the bending process. When the plate is about to shift, the robot system drives motor 21 to start, which in turn drives threaded rod 22, pulley 23, and belt 24 to rotate. Threaded rod 22 then causes sliding shell 31, mounting shell 32, threaded column 33, clamping plate 34, and limiting plate 35 to move. This causes sliding shell 31 to move in the opposite direction of the plate's impending shift, thus achieving the effect of compensating for the shift when clamping plate 34 clamps the plate. In this process, not only is force used to clamp the plate, but also skill and feedback are employed to reduce the problem of plate shifting during bending.

[0043] It should be noted that the specific installation methods, circuit connection methods, and control methods of motor 21 and motor 51 used in this utility model are all conventional designs, and will not be described in detail here.
