Description

Technical Field

[0001] The utility model relates to the technical field of detection and positioning, in particular to a high-precision detection and positioning manipulator. Background Art

[0002] High-precision detection and positioning manipulators are one of the important devices in the field of industrial automation. By combining advanced sensor technology, control algorithms and mechanical structures, they can achieve high-precision detection, positioning and operation in complex working environments, and are widely used in many industries such as automobile manufacturing, electronic assembly, food processing, and pharmaceutical packaging.

[0003] In the prior art, the detection plate is usually directly installed at the bottom end of the lead screw. When the manipulator controls the detection plate to contact the product detection surface, the height of the product may be inconsistent during the product conveying process. Since the manipulator is controlled by the system and has high precision, the problem that the detection plate does not fit the product detection surface may occur during the actual detection process, which may lead to inaccurate product positioning and thus detection errors.

[0004] Therefore, it is urgent to improve the high-precision detection and positioning manipulator to solve the above existing problems. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a high-precision detection and positioning manipulator. The ball screw drives the detection plate to slide downward through the transition plate. When the detection plate contacts the product detection surface, the ball screw can continue to slide downward until the bottom end of the detection plate is completely attached to the product surface. At this time, the transition plate continues to slide downward, and the guide post extends out from the upper end of the transition plate. The spring can buffer the pressure generated by the ball screw to prevent product damage, effectively solving the problem that the detection plate does not fit the product due to the height error of the product, making the product positioning more accurate, and thus reducing the detection error.

[0006] In order to achieve the above purpose, the main technical solutions adopted by the utility model include:

[0023] The following will cooperate with the drawings and embodiments to detail the implementation manners of the present application, so as to fully understand the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects and implement accordingly.

[0024] As Figures 1 - 4 shown, the high-precision detection and positioning manipulator provided in this embodiment includes a manipulator body 1. A ball screw 2 is slidably arranged at the output end of the manipulator body 1. The manipulator body 1 is used to drive the ball screw 2 to slide downward. A transition plate 3 is fixedly connected to the bottom end of the ball screw 2. Flanges 4 are fixedly installed on the upper sides around the transition plate 3. A guide post 5 is slidably arranged inside the flange 4. The guide post 5 penetrates through the transition plate 3 and the flange 4 and extends below the transition plate 3. The guide post 5 has a guiding function. The cooperation between the guide post 5 and the flange 4 can prevent the detection plate 6 from tilting. The bottom end of the guide post 5 is fixedly connected to a detection plate 6. A spring 7 is fixedly arranged between the detection plate 6 and the transition plate 3. The spring 7 is sleeved outside the guide post 5. On the one hand, the spring 7 resets the detection plate 6, and on the other hand, it can buffer the pressure on the ball screw 2;

[0025] Among them, the ball screw 2 drives the detection plate 6 to slide downward through the transition plate 3. When the detection plate 6 contacts the product detection surface, the ball screw 2 can continue to slide downward until the bottom end of the detection plate 6 is completely attached to the product surface. At this time, the transition plate 3 continues to slide downward, and the guide post 5 extends out from the upper end of the transition plate 3. The spring 7 can buffer the pressure generated by the ball screw 2 to prevent product damage, effectively solving the problem that the detection plate 6 does not fit the product due to the height error of the product, making the product positioning more accurate, thereby reducing the detection error.

[0026] Furthermore, as Figure 1 , Figure 2 and Figure 3As shown in the figure, a limit ring 21 is fixedly connected to the bottom side of the ball screw 2. A connecting block 8 is fixedly installed on the outer side of the limit ring 21. The bottom end of the connecting block 8 is fixedly installed on the upper end of the transition plate 3 by bolts. An arc-shaped clamping block 9 is fixedly installed on the upper side of the connecting block 8 by bolts. The limit ring 21 is fixedly arranged inside the connecting block 8 and the arc-shaped clamping block 9. The bottom end of the ball screw 2 is fixedly connected to the upper end of the transition plate 3 through the connecting block 8 and the arc-shaped clamping block 9. The arc-shaped clamping block 9 and the connecting block 8 can clamp the limit ring 21, thereby realizing the connection between the ball screw 2 and the transition plate 3. When repairing and replacing the detection plate 6, only need to remove the arc-shaped clamping block 9 and the connecting block 8, then the detection plate 6 can be taken off, which is more convenient and faster than the traditional screw installation method.

[0027] Furthermore, as Figure 1 and Figure 4 shown, the manipulator body 1 includes a large arm 10 and a robotic arm 11 rotatably arranged at the output end of the large arm 10. A small arm 12 is rotatably arranged at one end of the robotic arm 11 away from the large arm 10. The ball screw 2 penetrates through the small arm 12 and extends to the upper and lower sides of the small arm 12. The detection plate 6 is arranged below the small arm 12 and can cover different movement ranges. An integrated interface 14 is fixedly arranged at the upper end of the small arm 12. The integrated interface 14 is convenient for accessing the system, which is beneficial to improving the flexibility of the manipulator body 1;

[0028] At the same time, as Figure 1 and Figure 4 shown, a bellows 13 is rotatably connected to the large arm 10. One end of the bellows 13 away from the large arm 10 is rotatably connected to the upper end of the small arm 12; the bellows 13 is used to protect the cable. The pipeline joints at both ends of the bellows 13 are rotatably connected to the upper ends of the large arm 10 and the small arm 12 at 90 degrees, which can reduce the torsional stress of the cable and extend the service life.

[0029] Still further, as Figure 1 and Figure 4 shown, two sliding plates 15 are fixedly installed at the bottom end of the manipulator body 1. The manipulator body 1 is slidably arranged on the linear slide rail on the side of the conveyor through the sliding plates 15. A distance sensor 16 is fixedly installed on one side of the sliding plate 15, which is convenient for the manipulator body 1 to be installed on the production line. The distance sensor 16 is used to measure the stroke of the manipulator body, which can greatly improve the detection efficiency of the product.

[0030] As Figures 1 - 4 shown, the principle of the high-precision detection and positioning manipulator provided in this embodiment is as follows:

[0031] The manipulator body 1 is used to drive the ball screw 2 to slide downward. The ball screw 2 drives the detection plate 6 to slide downward through the transition plate 3. When the detection plate 6 contacts the product detection surface, the ball screw 2 can continue to slide downward until the bottom end of the detection plate 6 is completely attached to the product surface. At this time, the transition plate 3 continues to slide downward, and the guide post 5 extends from the upper end of the transition plate 3. The spring 7 can buffer the pressure generated by the ball screw 2 to prevent product damage. When repairing and replacing the detection plate 6, only the arc-shaped block 9 and the connecting block 8 need to be removed, and then the detection plate 6 can be taken off, which is convenient and fast.
