Description

Technical Field

[0001] The utility model relates to the technical field of industrial robots, in particular to a visual positioning device for an industrial robot. Background Art

[0002] Industrial robots are multi-joint manipulators or multi-degree-of-freedom machine devices widely used in the industrial field. They have a certain degree of automation and can achieve various industrial processing and manufacturing functions by relying on their own power and control capabilities.

[0003] In the actual use of existing industrial robots, corresponding visual positioning devices are needed to position products to ensure the accuracy of product grasping. Most of the existing visual positioning devices are visual positioning cameras. In actual use, due to the presence of dust in the factory working environment, dust will adhere to the surface of the positioning camera, thereby affecting the accuracy of positioning, and then affecting the accuracy of robot grasping. In addition, most visual cameras are directly fixed with bolts, which is not convenient for disassembly, inspection and maintenance. Therefore, we propose a visual positioning device for industrial robots. Utility Model Content

[0009] As a preferred embodiment of the utility model, a groove is provided on one side wall of the limiting plug, a steel ball is arranged in the groove, a spring is fixed to the bottom of the steel ball, the tail end of the spring is fixedly connected to the bottom of the inner cavity of the groove, a circular groove is provided on the inner wall of the limiting slot corresponding to the steel ball, and the steel ball is clamped in the circular groove.

[0010] By adopting the above technical solution, the limiting plug block and the limiting slot can be limited after being plugged in, thereby ensuring the stability of the connection. At the same time, when disassembly is required, the steel ball can compress the spring to disengage from the circular groove by pulling, so that disassembly is not hindered.

[0011] As a preferred embodiment of the utility model, bolts are threadedly penetrated on both sides of the outer wall of the movable rod, and one end of the bolt is rotatably connected to a corresponding position of a side wall of the brush plate.

[0013] As a preferred embodiment of the present invention, mounting holes are provided at four corners of the surface of the mounting plate.

[0014] By adopting the above technical solution and setting the mounting holes, it is convenient to install and fix the entire device.

[0015] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0016] The technical solution of the present application is an industrial robot visual positioning device, which can drive the screw to rotate through the screw motor, drive the screw slider to move, and thus drive the movable rod to move back and forth, so that the brush plate inside the movable rod can be used to wipe the visual camera, so as to achieve automatic cleaning, ensure the accuracy of the visual camera to capture the picture, and then ensure the grasping accuracy of the industrial robot, and at the same time, the rotating bolt can adjust the fit between the brush plate and the visual camera, so as to ensure the cleaning effect;

At the same time, after installation, the steel ball can be stuck in the matching circular groove under the push of the spring, thereby ensuring the stability of the connection and avoiding falling off.
