Description

Technical Field

[0001] This application relates to the field of visual recognition technology, and in particular to an intelligent visual recognition system. Background Technology

[0002] The shape and dimensional accuracy of shell-type workpieces affect the aesthetics of the assembled equipment. Generally, after the assembly of shell-type workpieces is completed, visual inspection is required to identify and form a model file, which is then compared with a standard model to determine the processing error.

[0003] However, existing intelligent vision recognition systems have the following drawbacks: for example, the positioning accuracy of moving the workpiece from the installation position to the detection position depends too much on the accuracy of the lead screw, which makes the cost of intelligent vision recognition systems high. Summary of the Invention

[0004] The purpose of this application is to provide an intelligent visual recognition system that utilizes a common lead screw structure for high-precision positioning and detection.

[0005] To achieve the above objectives, this application provides an intelligent visual recognition system, including a device body, a moving component, and a recognition module. A recognition cavity is provided on one side of the device body. The moving component is installed inside the recognition cavity and is used to move the workpiece to the detection position inside the recognition cavity. The recognition module is installed inside the recognition cavity and is used to scan and recognize the workpiece at the detection position.

[0006] Specifically, the moving component includes a base platform, a lead screw assembly, a mounting platform, a positioning block, and a limiting block. The base platform is fixedly connected to the bottom of the recognition cavity. The lead screw assembly is mounted on the top of the base platform, and the mounting platform is connected to the moving platform of the lead screw assembly via a rubber block. A positioning block is fixedly connected to the base platform at a position corresponding to the detection position. A limiting block corresponding to the positioning block is fixedly connected to the mounting platform.

[0007] In the above scheme, the movable stage of the lead screw assembly is connected to the mounting stage via rubber blocks. The mounting stage, which supports the workpiece, can move slightly relative to the movable stage of the lead screw assembly. When the workpiece is actually moved, the limiting block and the positioning block on the mounting stage cooperate to position it. This structural design makes the positioning accuracy of the mounting stage independent of the accuracy of the lead screw assembly. Ordinary lead screw assemblies can complete the high-precision movement of the workpiece to the detection position, meet the scanning and detection requirements of the recognition module, and reduce the cost of the intelligent vision recognition system.

[0008] As a preferred embodiment, a grating door is fixedly installed at the opening of the identification cavity of the main body of the device. The grating door is used to sense whether there are foreign objects at the opening of the identification cavity, so as to ensure the safety of the operation of the main body of the device.

[0009] As another preferred embodiment, the recognition module includes a five-axis robotic arm and a scanning box. The five-axis robotic arm is fixedly connected to the inner wall of the recognition cavity, and the scanning box is installed at the moving end of the five-axis robotic arm.

[0010] The scanning box is moved by a five-axis robot, enabling it to identify the shape and size of the workpiece from all directions and multiple angles.

[0011] Further preferably, a supplementary light is provided on one side of the scanning box, which can illuminate the working process of the scanning box and ensure the scanning effect.

[0012] As a preferred embodiment, the lead screw assembly includes a lead screw component rotatably mounted on a base platform and driven by a servo motor, and a movable stage cooperating with the lead screw component. The movable stage is slidably engaged with the base platform. The servo motor drives the lead screw component to rotate, and the lead screw component cooperates with the movable stage, thereby driving the movable stage to move linearly.

[0013] In a further preferred embodiment, a side frame is fixedly connected to the side of the mobile platform, and a sliding member is fixedly connected to the bottom of the side frame; a guide member is fixedly installed on the top of the base platform, and the guide member slides in cooperation with the sliding member to further increase the stability of the mobile platform's movement.

[0014] In a further preferred embodiment, a plurality of frames are fixedly installed on the top of the mounting platform, and the plurality of frames form a support system corresponding to the workpiece, and the support system formed by the plurality of frames supports the workpiece.

[0015] Furthermore, each of the mold frames is fixedly connected to the top of a protective block made of plastic, which can effectively prevent the mold frame from damaging the workpiece.

[0016] Compared with the prior art, the beneficial effects of this application are as follows:

[0017] (1) By connecting the moving stage of the lead screw assembly to the mounting stage through rubber blocks, the mounting stage used to support the workpiece can move slightly relative to the moving stage of the lead screw assembly. When the workpiece is actually moved, the limiting block and the positioning block on the mounting stage cooperate to position it. This structural design makes the positioning accuracy of the mounting stage independent of the accuracy of the lead screw assembly. Ordinary lead screw assemblies can complete the high-precision movement of the workpiece to the detection position, meet the scanning and detection requirements of the recognition module, and reduce the cost of the intelligent vision recognition system.

[0018] (2) By fixing and installing a grating door at the opening of the identification cavity of the main body of the equipment, the grating door is used to sense whether there are foreign objects at the opening of the identification cavity, so as to ensure the safety of the operation of the main body of the equipment.
