Description

Technical Field

[0001] The utility model relates to the technical field of automation, in particular to an automatic loading and unloading device for workpieces. Background Art

[0002] With the rapid development of the manufacturing industry, the speed of product updates and iterations is getting faster and faster. For the discrete processing industry, higher requirements are placed on the flexibility of automated processing, as well as higher requirements on automated debugging speed, processing efficiency, and repeated positioning accuracy.

[0003] Traditional fixed-installation automation units are difficult to teach, have low flexibility, are difficult to modify after fixed installation, have a long cycle, and are not suitable for discrete processing of multiple varieties and small batches. The 3D vision-guided composite robotic arms on the market have poor repeatability and high difficulty in posture control. Since the positioning accuracy of vision-guided systems is at the millimeter level, they have poor adaptability to scenarios that require high repeatability and are difficult to debug.

The loading and unloading robot arm realizes the automatic loading and unloading of the workpieces under the control of the control element, without introducing unnecessary errors, thereby reducing the error rate in processing. In addition, the material bin and the loading and unloading robot arm are arranged on a movable frame, which can realize the movement of the automatic loading and unloading device of the workpiece between different stations. Since the movable frame is not fixedly installed on the ground, when the station needs to be switched, it only needs to disconnect the power supply and communication to quickly disassemble and install it to the station to be processed. It has high flexibility, solves the problem that the automation unit is difficult to adapt to complex production conditions, simplifies the complexity of debugging for switching stations, and improves debugging efficiency and processing efficiency.

[0008] Furthermore, it also includes a visual acquisition element for identifying the characterization information of the workpiece to be processed and performing angle correction on the workpiece to be processed.

[0009] By adopting the above-mentioned technical means, the visual acquisition element is used to identify the characterization information and correct the angle, so as to quickly confirm the processing program suitable for the workpiece to be processed, and through angle correction, the processing accuracy of the workpiece to be processed is guaranteed.

[0010] Furthermore, the visual acquisition element includes a substrate and a line scan camera, an industrial camera and a rotatable support column fixed on the substrate. The information acquisition ends of the line scan camera and the industrial camera are both pointed to the rotatable support column.

[0013] By adopting the above-mentioned technical means, the L-shaped positioning part is used to realize the rapid positioning of the rectangular material tray, thereby ensuring that the relative position accuracy between the loading and unloading robot arm and the rectangular material tray can quickly meet the design requirements, so that after switching the work station, the grasping point can be quickly confirmed, thereby improving the processing efficiency.

[0014] Furthermore, a plurality of anti-slip feet are fixed to the bottom end of the movable frame.

[0015] By adopting the above technical means, the movable frame is effectively prevented from moving on the ground, and the horizontality of the top surface of the movable frame can be adjusted by selecting highly non-slip feet, with a simple structure and low cost.

[0016] Beneficial effects of the utility model:
