Description

Technical Field

[0001] The utility model relates to the technical field of automobile manufacturing, in particular to a workpiece sorting device for an automobile parts production line based on vision. Background Art

[0002] In recent years, with the rapid development of electronic technology and computer technology, the software and hardware technology of machine vision has also developed rapidly, and the application scope of machine vision has become wider and wider. Machine vision can replace and surpass the human eye, and its addition can realize more powerful and efficient functions.

[0003] Cars are widely used in people's daily lives and have become the preferred means of transportation for people. The demand for cars has greatly increased, and the demand for various auto parts has also greatly increased. The production line is indispensable in the production process of auto parts. As the demand increases, the production speed must also follow up. Most of the existing production lines are manually sorted, and manual sorting will inevitably result in many missed inspections. In addition, long-term inspections will cause eye fatigue, which will also cause missed inspections of auto parts. Due to the slow speed of manual sorting, high missed inspection rate, and poor reliability, it is obvious that it can no longer meet the existing sorting needs. Utility Model Content

[0004] The purpose of the utility model is to provide a workpiece sorting device for an automobile parts production line based on vision, which can effectively reduce the fault tolerance rate in the sorting process and effectively improve the sorting efficiency to meet the growing demand for automobile production.

[0005] To achieve the above-mentioned purpose, the utility model provides a vision-based workpiece sorting device for an automobile parts production line, comprising a workbench, a conveying component is provided above the workbench, a detection component is provided above the conveying component, a sorting component is provided at the end of the conveying component, and a fixed bracket is provided at the bottom of the workbench.

[0021] Embodiment 1

[0022] like Figure 1-3 As shown, the utility model provides a workpiece sorting device for an automobile parts production line based on vision, including a workbench 1, a conveying assembly is arranged above the workbench 1, the conveying assembly includes a conveyor belt 2, and electric shafts 3 are arranged on both sides of the conveyor belt 2. The rotation of the electric shaft 3 can drive the conveyor belt 2 to move, thereby driving the workpiece to move to the right. The two ends of the electric shaft 3 are arranged above the workbench 1 through a fixing rod 4, and a gap is left between the workbench 1, thereby facilitating the rotation of the electric shaft 3 and the conveyor belt 2. One end of the right electric shaft 3 is connected to the output end of the motor 17, and the motor 17 can drive the electric shaft 3 to rotate.

[0023] A detection component is provided above the conveying component, and the detection component includes a U-shaped fixing frame 5, which is fixed on the workbench 1 and spans above the conveyor belt 2. A scanning unit 15 is provided at the crossbeam of the U-shaped fixing frame 5, and the scanning head of the scanning unit 15 is vertically arranged with the conveyor belt 2. The workpieces to be sorted enter the conveyor belt 2 regularly, which can facilitate subsequent sorting. The workpieces to be sorted move to the right with the conveyor belt 2. When passing directly under the scanning unit 15, the scanning head can scan and identify the workpieces, and then the scanning unit can transmit the identified image to the central controller 16.

[0024] A sorting assembly is provided at the end of the conveying assembly, and the sorting assembly includes two inclined slideways, namely, a first slideway 6 and a second slideway 7. The entrance ends of the two slideways intersect, and a partition plate 8 is provided at the entrance end of the slideway. One side of the partition plate 8 is fixed to the entrance end of the slideway by a rotating rod 9. A rotating motor 13 is provided at the bottom of the slideway through a first fixed frame 12, and the output end of the rotating motor 13 is connected to the rotating rod 9. The rotating direction of the partition plate 8 can be controlled by the rotating motor 13, and finally the running track of the workpiece on the slideway can be changed, so that the workpiece can be sorted.

[0025] The workbench 1 is provided with a central controller 16, which is electrically connected to the scanning unit 15 and the rotating motor 13. Before sorting the workpieces, a standard part model will be imported into the central controller 16 to facilitate the subsequent workpiece sorting. The central controller 16 can compare the recognized image with the imported standard part model. If the workpiece recognized by the scanning head is flawless and standard, the central controller 16 controls the rotating motor 13 to rotate forward, so that the partition plate 8 rotates counterclockwise until the edge of the partition plate 8 contacts the inner wall of the slideway, and the workpiece with better quality slides out of the first slideway 6 and finally enters the finished product collection box;

[0026] If the scanned workpiece is defective, the partition plate 8 is controlled to rotate clockwise until the edge of the partition plate contacts the inner wall of the slideway, and the inferior workpiece slides away from the second slideway 7 and finally enters the defective collection box. Figure 1 The schematic diagram of the middle partition plate 8 shows this situation.

[0027] A fixed bracket 10 is provided at the bottom of the workbench 1, and the height of the fixed bracket 10 can be adjusted as needed, so that the height of the workbench 1 and the conveyor belt 2 can be changed to meet various needs.

[0028] The auto parts sorted in the device are some small devices, and the devices can be placed stably on the conveyor belt 2. When the devices are transferred to the conveyor belt 2, the upward surface of the devices is fixed. The upward surface of the devices is prone to defects during the production process, which can facilitate the identification of the scanning unit 15.

[0029] Embodiment 2

[0030] A six-axis robot arm 11 is provided on the left side of the workbench 11, and a vacuum suction cup 14 is provided at the head end of the six-axis robot arm 11. When the use site of the device is limited and the workpieces to be sorted cannot be normally sent into the transmission component through the front conveyor belt, the six-axis robot arm 11 can be used to place the unsorted workpieces one by one on the conveyor belt 2 in the transmission component.

[0031] Therefore, the utility model adopts the above-mentioned vision-based workpiece sorting device for automobile parts production line, which can effectively reduce the fault tolerance rate in the sorting process, and at the same time can effectively improve the sorting efficiency to meet the growing demand for automobile production.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that they can still modify or replace the technical solution of the utility model with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of the utility model.
