Description

Technical Field

[0001] The utility model relates to a detection device, in particular to a detection device based on a micro-electromechanical scanning galvanometer, belonging to the technical field of scanners. Background Art

[0002] In the process of processing and producing parts, in order to improve the quality, it is necessary to inspect their surfaces. The current inspection method is to transport the workpiece to a fixed inspection station and then measure and inspect its surface. During the transportation process, the parts will inevitably tilt and deviate from the path, that is, it cannot be guaranteed that the parts can enter the inspection station vertically, so that the scanning mechanism cannot scan and inspect the parts at the optimal angle, resulting in deviations in detection accuracy.

[0003] Chinese patent application number: CN202121310119.0 discloses a product scanning and detection device for an automated production line, in order to solve the problem that the detection and scanning device on the existing automated production line cannot meet the scanning and detection operations at multiple angles. A lower conveying mechanism is provided at the lower part of the main body of the scanning and detection device, and a reserved groove is provided on the upper end surface of the main body of the scanning and detection device. A rotating disk is provided inside the reserved groove, and a second fixed rod body is provided on both sides of the rotating disk, and there are two second fixed rod bodies. The two second fixed rod bodies are rotatably connected to the rotating disk through a second rotating shaft body, and there are two second rotating shaft bodies. A third fixed rod body is provided on the lower end surface of the two second fixed rod bodies, and the third fixed rod body is rotatably connected to the second fixed rod body through a third rotating shaft body, and there are two third rotating shaft bodies. The lower end surfaces of the two third fixed rod bodies are provided with telescopic rod bodies.

[0004] This patent sets up a conveyor disc and a conveyor rotating belt, so that the product can be transported in time after being inspected by the device. However, due to the lack of a positioning structure for the product, the products manually placed on the conveyor disc cannot ensure that each component can be placed in a straight line on the inspection station, so that the scanning mechanism cannot scan and inspect the components at the optimal angle, resulting in a deviation in the inspection accuracy. Therefore, we propose a detection device based on a micro-electromechanical scanning galvanometer. Utility Model Content

[0022] See also Figure 1-Figure 3 The embodiment of the utility model provides a detection device based on a micro-electromechanical scanning galvanometer, including a conveying mechanism 1 and a scanning mechanism 4. A positioning assembly 6 is arranged on the top of the conveying mechanism 1. The positioning assembly 6 includes a bracket 61. The bracket 61 is fixedly installed on the top of the conveying mechanism 1. The inside of the bracket 61 is rotatably connected with a bidirectional screw rod 62. The outer wall of the bidirectional screw rod 62 is symmetrically threaded with two sliding rods 63. The bottom ends of the two sliding rods 63 extend to the outside of the bracket 61 and are fixedly connected with a positioning rod 64. The bottoms of the two positioning rods 64 are in contact with the surface of the conveying mechanism 1. One end of the bidirectional screw rod 62 extends to the outside of the bracket 61 and is fixedly connected with a handle 65. By rotating the handle 65, the handle 65 drives the bidirectional screw rod 62 to rotate, the bidirectional screw rod 62 drives the slide rod 63 to slide, and the slide rod 63 drives the positioning rod 64 to slide, so that the two positioning rods 64 can be adjusted according to the width of the parts, so that the parts can enter the scanning area in a straight line state for inspection one by one, thereby improving the inspection accuracy of the parts; the surface of the conveying mechanism 1 is slidably connected to the guide rod 8, and the inner wall of the bracket 2 is symmetrically fixedly connected to two rows of lights 5. By setting the row of lights 5, the scanning mechanism 4 can inspect the parts in an environment with sufficient light, thereby improving the inspection accuracy, and the touch screen 12 is electrically connected to the telescopic rod 3, the scanning mechanism 4 and the motor 10 respectively.

[0023] Furthermore, an L-shaped bracket 7 is fixedly connected to the top of the conveying mechanism 1, a motor 10 is fixedly connected to the top of the L-shaped bracket 7, a vertical rod 9 is fixedly connected to the top of the guide rod 8, an output end of the motor 10 passes through the L-shaped bracket 7 and is fixedly connected to the top of the vertical rod 9, and two boxes 11 are provided at the bottom of the conveying mechanism 1. The motor 10 drives the vertical rod 9 to rotate, and the vertical rod 9 drives the guide rod 8 to rotate, thereby realizing the diversion of qualified parts and defective parts, reducing labor, and realizing automatic sorting; a touch screen 12 is fixedly connected to the outer wall of the conveying mechanism 1, a bracket 2 is fixedly connected to the top of the conveying mechanism 1, a telescopic rod 3 is fixedly connected to the bottom of the bracket 2, and the telescopic end of the telescopic rod 3 is fixedly connected to the top of the scanning mechanism 4.

[0024] Working principle: first turn the handle 65, the handle 65 drives the bidirectional screw 62 to rotate, the bidirectional screw 62 drives the slide bar 63 to slide, the slide bar 63 drives the positioning rod 64 to slide, so that the distance between the two positioning rods 64 is slightly larger than the width of the parts to be detected, and then the parts are placed on the conveying mechanism 1, and the parts begin to be conveyed. It should be noted that the end of the positioning rod 64 close to the beginning of the conveying mechanism 1 is set as an inclined surface, that is, the distance between the two positioning rods 64 is large at first and then small. At this time, the parts enter along the slope of the positioning rod 64. Due to the rear half of the two positioning rods 64 At this time, the parts are corrected along the inner wall of the positioning rod 64, that is, the parts can enter the scanning area in a straight line. At the same time, under the illumination of the row of lights 5, the scanning mechanism 4 scans and detects the parts. The qualified parts fall into the front box 11 along the angle of the guide rod 8. If the detected parts are defective, the touch screen 12 controls the motor 10 to rotate in the opposite direction, so that the guide rod 8 rotates 90 degrees counterclockwise. At this time, the defective parts fall into the rear box 11 along the angle of the guide rod 8, thereby reducing the workload of manual sorting.
