Description

Technical Field

[0001] The present invention relates to the technical field of industrial automation equipment, specifically an intelligent grinding workstation for middle components. Background Art

[0002] The middle component grinding workstation is a common device in modern industrial production, mainly used for processing various workpieces such as beveling, surface polishing, and grinding. Through the automated grinding workstation, production efficiency can be improved, manual operations can be reduced, and the surface quality and consistency of the workpieces can be enhanced. With the continuous growth of industrial automation requirements, the grinding workstation is gradually developing towards high precision and high efficiency to meet the processing needs of different types of workpieces.

[0003] The existing middle component grinding workstation usually consists of a grasping mechanism, a grinding mechanism, and a control system. The grasping mechanism is responsible for transporting the workpiece from the loading area to the grinding area, and the grinding mechanism performs surface treatment on the workpiece through fixed grinding tools. The working principle of this device is to control the grasping and grinding operations through a preset program to achieve the automated handling and processing of the workpiece.

[0004] The existing middle component grinding workstation has deficiencies in workpiece identification and positioning, grasping stability, and flexible adaptability of the device. Firstly, due to the lack of precise visual scanning and real-time control, the device often has inaccurate identification problems when processing workpieces with different shapes and positions. Secondly, the single adsorption method of the grasping mechanism causes the workpiece to be prone to offset or instability during transportation, affecting the grinding accuracy. In addition, traditional grasping and grinding equipment lacks flexibility when facing workpieces of different specifications and is difficult to automatically adjust to meet diverse production requirements. Summary of the Invention

[0005] In view of the deficiencies of the prior art, the present invention provides an intelligent grinding workstation for middle components, which solves the problems of inaccurate identification, unstable grasping, and poor adaptability of the existing equipment.

[0006] To achieve the above objectives, the present invention is realized through the following technical solutions: An intelligent grinding workstation for middle components, including:

[0007] A workpiece, which is the target component to be processed in the device;

[0008] A grasping mechanism, which is arranged outside the workpiece, used to provide an area for placing the workpiece and achieve the automated handling of the workpiece without manual operation by employees. The grasping mechanism includes a movable z-axis module and a magnetic adsorption component. The magnetic adsorption component is located at the bottom of the z-axis module, and the magnetic adsorption component is used to adsorb the workpiece. The z-axis module is used to lift or lower the workpiece, and can keep the workpiece stable during the processing with the combined action.

[0009] A vision scanning system, fixedly connected to the bottom of the crossbeam of the grasping mechanism, is used to realize automatic identification and pose analysis of workpieces, so as to assist the grasping and handling of the transportation mechanism and the grasping mechanism, and avoid ineffective processing at the same time;

[0010] A grinding mechanism, arranged in the middle of the grasping mechanism, is used for automatically chamfering and surface grinding operations on the transported workpieces.

[0011] Preferably, the grasping mechanism includes two guide rails. A grasping truss is slidably connected to the upper sides of the two guide rails. A z-axis module is slidably connected to the crossbeam of the grasping truss. The output end of the z-axis module is fixedly connected to a connecting plate. A plurality of telescopic cylinders are fixedly connected to the bottom of the connecting plate. The output end of the telescopic cylinder is slidably connected to a cylinder plunger. A magnetic attraction assembly is fixedly connected to the end of the cylinder plunger away from the telescopic cylinder. The magnetic attraction assembly includes a plurality of partitions. The partitions are fixedly connected to the outside of the telescopic cylinder. A plurality of sliding rods are slidably connected to the middle of the partitions. The bottom ends of the sliding rods are fixedly connected to electromagnets. A locking nut is threadedly connected to the outer periphery of the sliding rods. A return spring is sleeved on the outer periphery of the sliding rods. The return spring is fixedly connected between the partition and the electromagnet.

[0012] Preferably, a discharging position is arranged on one side of the loading position away from the vision scanning system.

[0013] Preferably, the grinding mechanism includes two support plates. Both of the two support plates are located in the middle of the grasping mechanism. Rack bars are fixedly connected to the upper sides of the two support plates. A grinding truss is slidably connected to the support plates through slide rails. Two driving motors I are fixedly connected to the outside of the grinding truss. The output ends of the two driving motors I are fixedly connected to gears. The gears are meshed with the rack bars. A z-axis module II is slidably connected to the crossbeam of the grinding truss. A driving motor II is fixedly connected to the moving end of the z-axis module II. The output end of the driving motor II is fixedly connected to a grinding head. The grinding head is in contact with the workpiece.

[0014] Preferably, a belt transportation mechanism is arranged above the loading position and the discharging position, which is used to transport workpieces, so as to realize loading and unloading operations.

[0015] Preferably, the grinding head includes a variety of replaceable grinding tools, which can automatically select appropriate grinding tools for operation according to processing requirements. The grinding head is connected to the driving motor II through bolts.

[0016] Preferably, the vision scanning system includes an image processing module. The image processing module analyzes the image data to generate the position information and pose parameters of the workpiece, and transmits the information to the control systems of the grasping mechanism and the grinding mechanism.

[0017] Preferably, the image processing module analyzes the geometric features of the workpiece through a built-in image analysis algorithm to determine the edge, contour, shape, size, and spatial attitude of the workpiece.

[0018] Preferably, the vision scanning system further includes a control unit, which is connected between the image processing module and the control system of the grasping mechanism. The control unit is used to receive the position information and attitude parameters of the workpiece, and generate control instructions by analyzing these data to guide the grasping mechanism to perform accurate grasping and handling operations.

[0019] Preferably, the image processing module of the vision scanning system is equipped with a programmable interface, which can adjust the resolution, scanning range, and image processing parameters of the camera according to production requirements to adapt to workpieces of different specifications and shapes.

[0020] Working principle: When in use, after the workpiece is sent to the loading area, the vision scanning system captures the image of the workpiece through a high-resolution camera, and uses the image processing module to analyze the position information and attitude parameters of the workpiece, and transmits them to the control systems of the grasping mechanism and the grinding mechanism. At this time, under the action of the guide rail and the grasping truss, the grasping mechanism drives the magnetic adsorption component to move above the workpiece, and drives the z-axis module 1 to move the magnetic adsorption component downward. First, the electromagnet contacts the workpiece, so as to grasp the workpiece. When processing workpieces of different shapes, by driving the telescopic cylinder to contract, the electromagnet compresses the return spring, so that the electromagnet lifts and does not contact the workpiece. At this time, it can be avoided that the redundant electromagnet grabs the table for placing the workpiece when grasping the workpiece;

[0021] At the same time, through the cooperation of the support plate and the grinding truss, the z-axis module 2 can be moved in parallel. The z-axis module 2 can move the driving motor 2 up and down. At the same time, under the action of the driving motor 2, the grinding head can rotate, so as to cooperate with the grasping mechanism to move the workpiece above the grinding head and then adjust the position, so as to complete the processing operation of the workpiece;

[0022] After the processing is completed, the workpiece is placed above the unloading position and the unloading work is carried out. The loading and unloading operations are both belt conveying mechanisms, and the belt conveying mechanism is a prior art and will not be elaborated in this article.

[0023] The present invention provides an intelligent grinding workstation for middle components. It has the following beneficial effects:

[0024] 1. Through the coordination of the vision scanning system and the control unit, the present invention realizes the accurate identification and real-time positioning of the workpiece, and cooperates with the efficient linkage of the grasping mechanism and the grinding mechanism, making the workpiece handling and processing processes automated and integrated, improving production efficiency and processing accuracy.

[0025] 2. By combining the magnetic attraction component and the cylinder lifting, the present invention realizes the stable grasping and handling of workpieces. Regardless of how the shape and weight of the workpieces change, it can ensure the position stability during operation, thereby improving the operation reliability of the equipment.
