Description

Technical Field

[0001] The present invention relates to the technical field of visual detection, and more particularly to a device and method for detecting the surface flatness of an electrical cabinet door. Background Art

[0002] After the processing of the electrical cabinet door is completed, the flatness quality of the plate needs to be identified. The flatness detection device is a device that uses optical principles to detect the flatness of the surface of an object. The industrial camera captures the surface of the plate and transmits the image to the controller. The flatness of the plate is judged based on the image information. The detection results can help people determine whether the detected item is qualified.

[0003] At present, the flatness and defect detection of electrical cabinet doors are mostly carried out with the naked eye. Staring at the electrical cabinet doors for a long time is likely to cause visual fatigue and mental fatigue, and is prone to misjudgment. At the same time, there is also a prior art method of conveying the electrical cabinet doors to the bottom of the detection device for detection by a conveyor belt. This detection method cannot detect defects on the back of the electrical cabinet doors. In order to realize the detection of the back of the electrical cabinet doors, the electrical cabinet doors need to be clamped and turned over. During the clamping and turning process, the electrical cabinet doors are easily pinched and deformed, affecting the quality of the electrical cabinet doors and the normal implementation of subsequent flatness and defect detection.

[0045] Working principle of the second embodiment: By placing the electrical cabinet doors to be inspected one by one on the surface of the conveyor belt 25, in the initial state, under the elastic force of the arc spring 42, the bottom of the arc block 41 is driven to press against the surface of the baffle 39. At this time, the first active roller 49 is placed under the transfer rod 75, and the surface of the conveyor belt 25 is flush with the surfaces of the driven rollers 48 on the conveying part 6. The drive motor 27 is controlled to start to drive the corresponding transmission roller to rotate, thereby driving the conveyor belt 25 to transmit the electrical cabinet door closest to the conveying part 6 to the conveying part 6. The drive motor 27 is turned off and the servo motor 53 on the corresponding conveying part 6 is controlled to start, driving the first active roller 49 to rotate, so that the electrical cabinet door is transported to the inner wall of the U-shaped seat 36, completing the transportation of the electrical cabinet door.

[0046] The control starts the rotating motor 34 to drive the rotating part 5 to rotate, so that the corresponding conveying part 6 and the placed electrical cabinet door rotate into the visual inspection room 2. At this time, the visual inspection part is facing the surface of the electrical cabinet door; the fill light 69 is respectively arranged on both sides of the industrial camera 68, and the fill light 69 is used to illuminate the surface of the electrical cabinet door. The surface condition of the electrical cabinet door is photographed by the industrial camera 68, and the image is transmitted to the controller 28. The flatness of the electrical cabinet door and defect detection are judged according to the image information. The detection results can facilitate people to judge whether the inspected items are qualified.

[0047] In the initial state, the square tube 12 is placed above the rotating rod 14. At this time, the transfer part 13 is placed obliquely above the conveying part 6. At the same time, the driven roller 48 on the transfer part 13 is placed below the sliding column 44 (that is, the transfer part 13 is in an inverted state); after completing the detection of the surface of the electrical cabinet door, the third electric push rod 58 is controlled to start and drive the ear plate 57 together with the fixed plate 17 to move toward the direction close to the conveying part 6. During this process, the first ball head 20 first slides along the inside of the straight guide groove 15, and the second ball head 45 is squeezed by the fixed plate 17, driving the transfer part 13 to move toward the direction close to the conveying part 6, until the two mounting plates 43 slide along the surface of the U-shaped seat 36 in the flat state. After the first ball head 20 slides from the straight guide groove 15 into the spiral groove 16, the transfer part 13 continues to move toward the conveying part 6. It rotates while moving in the direction close to the conveying part 6, driving the U-shaped seat 36 to rotate synchronously, until the transfer part 13 rotates to the bottom of the conveying part 6, the two fit together, and the electrical cabinet door inside the conveying part 6 falls into the transfer part 13, with the back of the electrical cabinet door facing upward and aligned with the visual inspection part. At this time, the arc spring 42 is compressed, and the corresponding conveying part 6 is in an inverted state (that is, the first active roller 49 is placed above the transfer rod 75). The control starts the rotating motor 34 to drive the rotating part 5 to rotate 90°, so that the conveying part 6 in the inverted state rotates away from the visual inspection room 2. In this process, under the elastic reset force of the arc spring 42, the conveying part 6 is driven to rotate and reset, and the back of the electrical cabinet door is inspected for flatness and defects through the visual inspection part, thereby improving the inspection efficiency and accuracy.

[0048] When the test result shows that it is qualified, the corresponding servo motor 53 is controlled to drive the second active roller 50 to rotate, thereby transporting the electrical cabinet door to the corresponding sorting part 4 and outputting it through the corresponding sorting part 4; when the test result shows that it is unqualified, the second electric push rod is controlled to start to drive the lifting plate 54 to slide down, and the corresponding servo motor 53 is started to drive the third active roller 51 to rotate, transporting the electrical cabinet door to the sorting part 4 on the other side, and outputting it through the corresponding sorting part 4, completing the automatic sorting of qualified and unqualified electrical cabinet doors.

[0049] After the sorting is completed, the third electric push rod 58 is controlled to retract and reset, pulling the pushing part 10 to move and reset in the direction away from the conveying part 6. During this process, the transfer part 13 rotates and resets, and is inverted and placed obliquely above the conveying part 6.

[0050] For example three, please refer to Figure 1-15, this embodiment three makes the following improvements on the basis of embodiment two. Specifically, the visual inspection part includes a square column 62 fixed to the top of the visual inspection chamber 2; an upper stopper 63 is fixed to the side surface of the square column 62, and a lower stopper 64 is fixed to its bottom; a lifting seat 65 is provided with a sliding function on the square column 62; an extrusion spring 66 mounted on the square column 62 is fixedly connected between the lifting seat 65 and the lower stopper 64; a mounting seat 67 is fixed to the side of the lifting seat 65; an industrial camera 68 is fixed to the bottom of the mounting seat 67; a fill light 69 is symmetrically fixed to the bottom of the mounting seat 67; an inclined guide plate 70 is fixed to the top of the mounting seat 67; a first straight guide plate 71 and a second straight guide plate 72 parallel to each other are fixed at both ends of the inclined guide plate 70; a connecting rod 73 is fixed to the side surface of the fixed plate 17; and a third ball head 74 is fixed to the end of the connecting rod 73.

[0051] Working principle of the third embodiment: When the transfer part 13 is moving, the third ball head 74 slides along the surface of the second straight guide plate 72, the inclined guide plate 70 and the first straight guide plate 71 in sequence, so that the mounting seat 67 together with the industrial camera 68 and the fill light 69 slide down, automatically adjusting the detection distance between the visual inspection part and the electrical cabinet door, ensuring that the two detection distances of the electrical cabinet door surface and the back are consistent, thereby improving the accuracy of the detection.

[0052] A detection method for a surface flatness detection device for an electrical cabinet door, comprising the following steps: T1. The electrical cabinet door is transported to the adjacent horizontal conveying part 6 through the conveying frame 23, and the rotating part 5 is controlled to rotate so that the electrical cabinet door is rotated into the visual inspection room 2 and is placed directly under the visual inspection part. The flatness defect of the surface of the electrical cabinet door in the conveying part 6 is inspected by the visual inspection part.

[0053] T2. After the surface of the electrical cabinet door is inspected, the pushing part 10 is controlled to move toward the direction close to the conveying part 6. During the sliding of the first ball head 20 in the straight guide groove 15, the transfer part 13 in a horizontal state slides to above the conveying part 6. When the first ball head 20 slides into the spiral groove 16, the transfer part 13 moves and rotates at the same time, driving the conveying part 6 to rotate. When the transfer part 13 rotates to the bottom of the conveying part 6, the electrical cabinet door in the conveying part 6 falls into the transfer part 13. At this time, the bottom surface of the electrical cabinet door faces upward, and the conveying part 6 is separated from the transfer part 13 by controlling the rotation of the rotating part 5, and its bottom surface is inspected by the visual inspection part.

[0054] T3. After completing the inspection of both sides of the electrical cabinet door, qualified products are output through one group of sorting parts 4, and unqualified products are output through another group of sorting parts 4 set opposite to each other.

The electrical cabinet door is conveyed to an adjacent horizontal conveying section via a conveying frame. The rotating section is controlled to rotate so that the electrical cabinet door is rotated into the visual inspection chamber and placed directly below the visual inspection section. The visual inspection section then performs a surface flatness defect inspection on the electrical cabinet door in the conveying section. T2. After the surface of the electrical cabinet door is inspected, the pusher is controlled to move toward the conveying section. As the first ball head slides in the straight guide groove, the horizontal transfer section slides above the conveying section. After the first ball head slides into the spiral groove, the transfer section moves and rotates, driving the conveying section to rotate. When the transfer section rotates to just below the conveying section, the electrical cabinet door in the conveying section falls into the transfer section. At this point, the bottom surface of the electrical cabinet door faces upward. The rotating section is controlled to rotate, separating the conveying section from the transfer section, and the bottom surface is inspected by the visual inspection section. T3.
